Alcoholic Beverage

It is powerful and addictive this liquid is taken orally and often consumed in bundant quantities. Surveys say that adolescents and young adults are likely to drink. There are three basic types of alcoholic drinks are: Beer, Wine, Spirit. Their difference is what each is made of and percentage of alcohol content. Beer is made from fermented grains and has 3 to 6 percent of alcohol content while is made from fermented fruits and have alcohol content of 11 to 14 percent. Spirits are made from fermented distilling products. It usually contains 40-50 percent of alcohol.American Council Education says 12 ounce glass of beer, 5 ounces of wine and 1. 5 ounce shots f spirits contains the same amount of alcohol. Beer, wine and spirit have the same potential for intoxication and addiction. When a person consumes alcohol the drug acts on nerve cells deep in the brain. These are the well known signs that a person is drunk: the smell of alcohol on breath, irritability, loss of physical coordinati on, violent behaviour, loss of balance, incoherent speech, loss of consciousness, slowed thinking, blackouts, and Euphoria, an extreme happiness.According to the American Psychiatric Association, (1994) that alcohol use is continued despite knowledge of aving a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by alcohol. Frequent binge drinking or getting severely drunk more than twice is classed as alcohol misuse. According to research done through international surveys, the heaviest drinkers happen to be the United Kingdom's adolescent generation. Alcohol abuse affects about 10% of women and 20% of men in the United States, most beginning by their mid-teens.In Antipolo City, Philippines, many teenagers are now facing the problems of being addicted to alcoholic beverages. One major cause is depression and family problems. Teenagers who are facing this kind of problem suffer in terms of heath like disorders in their eating h abits. Other illnesses and diseases which they may have are liver cancer, migraines, and various sicknesses associated with their physiques. Where an alcoholic has experienced a sense of withdrawal in the same time period. According to http://www. sciencedaily. com/articles /a/alcoholism. tm alcoholism is the consumption of preoccupation with alcoholic beverage to the extent that this behaviour interferes. The chronic alcohol caused by alcoholism can result in sychological or physiological disorder. It is also called world's mostly drug use problems. Alcoholism is often progressive diseases says Ehrlich (2011). A person who is alcoholic typically craves for alcohol and drink and increases his tolerance for alcohol stated by Stoppler (2011) For this reason according to Langham (2010) they are causes of teen alcoholism depend on genetics and life experienced.Teens begin drinking before the age 15 according to Butler (2006) are more likely to develop a dependency on alcohol than those who begin drinking 21 years old. According to Langham (2010) following reason of alcoholism in teens is: Genetics or Family History, meaning a teenager comes from families who its family members are addictive in or emotional abuse in home but also in school. Another basis of alcoholism in teens is peer pressure, teens experience this kind of reason when a teenager feels that she or he is not accepted because there is something wrong to his or her personality or maybe he or she becomes alcoholic because of friends.Lack of parental support is one of the sources, teenager who regularly experiences this kind of trait is a person ho regularly experience harsh discipline, criticism, hostility and rejection of his or her parents and the foremost reason of alcoholism in teens is depression, a teenager convince himself or herself that alcohol will take away his or her sadness and make her feel better stated by Boyles (2012).If its so, this causes may lead to some teenagers in different dange rous effect like: decreasing of paying attention, difficulties in memory, drunk driving, suicide attempt, engaged in sexual activity , poor hygiene, breaking curfews, Hiding in their room, becoming verbally or physically busive toward others according to Palmera (2009)To understand teenagers. Parekh (2009) says that parents seek for understanding; they must always use the open communication for teens. To care by letting them be who they are, gaining the trust of the adolescent.

Indian Removal Act Essay

Known as having adopted an Indian child as his son, Andrew Jackson was quite fond of the Indian race; however, with pressure to expand westward, he needed to transfer the Indians farther west and soon became their worst enemy. Andrew Jackson’s Indian Policy was to move the Indians westward as peacefully as possible, for the tribes that stayed in the East Coast were annihilated. Also, moving them West will help them live longer, and there is a fair exchange for the tribes moving. Another important component is the gain of Western lands and the addition of American power; this will add on to America’s size and increase America’s authority. Jackson validates his actions by saying he will pay for the land the Indians inhabit, pay for their long journey West, also known as the Trail of Tears, and support them a little while their settling in. President Jackson also said if they move west, they will enjoy sovereignty forever. Jackson made the point that with the Indians gone there will be less conflict between them and state governments, it will allow for prosperous populations and cities to flourish, and the free land will add another line of defense for America. President Jackson’s attitude toward the Indians in his speech reveals that he wants the Indians gone so America can gain land and grow stronger. He uses words like â€Å"Red Men† and â€Å"Savages† to describe them, so they seem like outcasts. He makes it sounds like the Indians are a nuisance and if they move, they will prosper as a people. Jackson says, â€Å"†¦perhaps cause them gradually†¦to cast off their savage habits and become an interesting, civilized, and Christian community.† Overall, Jackson wants the Indians gone for his own benefit. He refers to them as uncivilized, uninteresting, and having savage habits, and was proving that he is just looking for a gain for his country, not the native people who have lived there forever.

Being Heard

Being Heard Being heard Is something Important because It gives your audience a chance to see different sides of yourself. Being heard could do as little as make someone feel content or very Important. Listening to one another could be very useful In that we obtain Information, understand, listen for enjoyment and last but not least learn. In a recent article that Ive read, Talking a stranger through the night by Sherry Antihistamine, a great portion of the message that she sends out, has all to do about listening.Making someone feel heard makes him or her feel understood and a connection has been built. As a young student that I am, I have yet to learn many useful tools that my parents, peers and most importantly my professors will teach me in the near future. Through that learning journey it is their Job to listen to us students in order for them to have fulfilled their task. What I believe I can bring to the table are many things. Personally I am very experienced In starting over having moved three times. My very first move was fromSpain to Chile, Chile to New Jersey and New Jersey to Texas. And here I am, big latexes. For all of my life I resented my parents for having to put me through all those moves but as I grew older, fonder and a tab wiser Im very thankful for everything. Many people would kill to start over or even move to a different country and my parents were able to give me that. Yes, starting over does suck but the beauty of it is that you get a chance to become a better and newer person. Meet new people and learn a new totally different type of culture than your own.One of my professors once told me that we all have a chance in going out to the world and making something of ourselves; Be a new person A new you. I am very thankful for the life that god has given to me. Even through the little bumps along the road, It makes you a stronger person right? Well I believe so. Life Is full of surprises. Every single human being In this planet has something unique to offer to the table. Not all of us are the same thats what makes every single person special. Some of us may be great at math or great at writing and some may not be DOD at those things at all.This is when we listen and learn from those who can teach us to become better. So to answer your question yes, you should listen to every single one of us. Give us a chance. Even if were wrong thats where you correct us and we then learn. Lets take Martin Luther King Jar. For example. He wrote an incredibly outstanding speech and spoke out and people took chance to believe in him but especially listen. How are people supposed to make a difference if their isnt anyone to be there to take a chance and listen.By starred Being heard is something important because it gives your audience a chance to see content or very important.

Did the Nazi corrupt 'volkish' ideals Discuss Essay

Did the Nazi corrupt 'volkish' ideals Discuss - Essay Example By the 1930’s Volkism had come to imply much more than its initial concepts of culture, heritage and value of a race to the German populous. The anti-Semitism and subsequent deeds that typifies Hitler’s reign had been building up among the German people for decades. The acceptance of the German public of Hitler and his government though irrational, was not unexplainable. To understand to what extent the Nazi Party distorted or extended the volkish ideology to fit its own agenda, one must first appreciate the original meaning and evolution of the concept prior to and during the rise of the Third Reich. This paper will briefly explain the history of volkish thought, its correlation to and how it became intertwined with the Nazi regime and explore the question; was Volkism a gentile concept unwittingly used as an of tool for propaganda or is it the underlying reason for the public sanctioning of aggressive military measures and racism? As the industrial age swept across Europe in the mid-1800’s it brought society new opportunities but also inadvertently served to increase the individual’s feeling of remoteness and a loss of personal belonging (Mosse, 1964, p. 13). As Germany became modernized, its people began to feel alone in their own culture and began to desire closer association to their community. â€Å"Joining the Volk was a way to intellectually rebel against this new, modern world. The Volk was an intermediary between the extremes of individuality and the quest for cosmic identity† (Mosse, 1964, p. 15). A major aspect in the Volk concept centered around the sense of belonging and familiarity along with a strong connection with the rural, pastoral locations of the homeland. Germans of the Volk saw themselves as biologically bonded to those of their community, country and was as one with spirit of the countryside from which they were born. This relationship with the natural surroundings legitimized a

Should the US Taxpayer Bail Out the US Automobile Industry Term Paper

Should the US Taxpayer Bail Out the US Automobile Industry - Term Paper Example Besides there exist questionable approaches and elements within the framework of most of the top US automakers, which if supported by a bailout, stand to persist. The fact is that the American automakers seek money from the US taxpayers to retain their status quo, rather then for embarking upon an ambitious program to weed out the inefficiencies and lacunas existing within their setup (Gattuso and Loris 1). The politicians prefer to justify such emergency measures by citing the massive losses incurred by the US automakers. Off course their exists ample truth in such claims. In October, the sales of GM fell by 45 percent (Gattuso and Loris 1). The Chrysler and Ford also reported respective plummeting of sales by 34.9 and 30.2 percent (Gattuso and Loris 1). The automakers ascribe this drastic drop in sales to the existing credit crunch. Still, one can not deny the reality that the US automakers did take many shoddy decisions before the credit crunch that unleashed the current crisis (Gattuso and Loris).

South Africas Native Population Essay Example | Topics and Well Written Essays - 1250 words

South Africas Native Population - Essay Example Eventually, South Africa's native population took over and the dominant group is no longer the white minority in that country. A dominant group is defined by who holds economic, political, social, or coercive power over the minority. b. A minority group is defined as the group that is dominated by the dominant group. Again, in South Africa, the minority groups were 90% of the population while the dominant group was only 10% of the overall population. The dominant group has the power over the minority group despite the numbers of either group. In South Africa, 10% of the population held the power over 90% of the population. C. Racial categories are considered social because they are a division of people based upon appearance only. Before genetics race was considered proof that there was a significant difference between peoples. Genetics proved that despite outward differences in appearance all people were part of one genetic race. Differences in appearance are the outward adaptation to climate or region. Racial categories are still used to divide peoples and those who hold prejudices against others base their prejudices upon the assumption that one racial make up is inferior to another. Again, genetics does not support this belief. Another reason race is a social issue is because it is easy to point to someone and point out their differences. Most often race is an issue for the dominant group and is defined by the dominant group. d. The main difference between race and ethnicity is that race is defined by the dominant group whereas ethnicity is self defined. Ethnicity can be defined by language, cultural activities, and religion. Sometimes ethnicity is defined by physical characteristics such as clothing or modesty. Ethnic groups located in the United States include Hispanics, American Indians, Jews, African Americans, and white Americans. Ethnicity can be identified by how people celebrate (Christmas for example.) and how people mourn their dead. Many African Americans share a common desire for foods that have been passed down from one generation to another. These include fried chicken and collard greens. Many Mexican Americans still prefer Mexican fare such as tortillas and refried beans. And, as more and more cultures assimilate in the United States the identification as American can include foods considered 'American' such as hot dogs and apple pie. Question 2 Three social paradigms exist. Each paradigm describes human behavior and society. Social scientists use social paradigms to explain their viewpoints about what is happening in society and why. Paradigms describe only and cannot be enacted or made to happen. Figure 1 (Fox Valley Technical College 2000) a. The Conflict Paradigm The social conflict paradigm is characterized by conflict and inequality. It is a paradigm that seeks to answer such questions as what are the social inequalities, where does the conflict exist, and are their winners or losers The conflict paradigm asserts that society is made up of everyday interactions. The best way to think of it is as a society of 'haves' and 'have-nots'. For example, when driving along the highway you can almost bet on what the income level or socioeconomic class a person is in by looking at the car they drive.  

Choose an invention.describe and evaluate the effects it has had on a Essay

Choose an invention.describe and evaluate the effects it has had on a particular area of human life - Essay Example Computers have indeed done much to better the way people happen to do things. In that respect, it is really heartening to acknowledge that healthcare is an aspect of human life that has been totally revolutionized by the advent of computers, and computers have actually totally transformed the modern healthcare.1 It is a fact that in the area of healthcare, health records of patients do play a very important role. In that context, computers have totally redefined the record keeping in the field of healthcare.2 Health records of patients are not only vital for management of maladies of individual patients, but they are also important to predict larger societal healthcare trends. Before the invention of computers the record keeping in healthcare happened to be manual. It was not only very tedious to register and maintain the records of thousands of patients, but it was also utterly difficult to retrieve the health records of individual patients when required. However, with the invention of computers, things have totally changed. Computers have digitalized the recording and filing of patient records, thereby making it much more efficient, practical and faster. Computer generated and stored patient records not only happen to be more lasting and reliable, but it is much easier to retrieve the rec ords of specific patients. In fact with the computer assisted record keeping, it takes only a second to retrieve the health records of any patient. The computer assisted record keeping also assures that in the event of any man made or natural calamity, the health records of patients remain safe and secure at the offsite data storage locations. The other way in which the computers have positively influenced healthcare is by empowering the patients and by extending the reach of healthcare. In the earlier times even the most basic healthcare information was not easily available. However, with the advent of computers in the area of healthcare, computers have become a readily

Evaluating the revenue recognition practices undertaken by the Assignment

Evaluating the revenue recognition practices undertaken by the software company - Assignment Example For this case, they need to bring this revenue down so that they can show the stakeholders the true financial statements according to the laid down rules in the International Accounting Standards. There are various accounting concepts and principles that were not adhered to by Isoft company thus why they showed higher revenue than they had actually realised. This paper will critically evaluate the revenue recognition practices which had been used by Isoft and it will also include an analysis of the potential economic and social consequences of these practices. For once, revenue should be earned. This means that anticipated incomes also referred to as receivables should not be recognized until such a time when they have been realized. According to the American accounting association, the term income includes realized net income add and not income only. Isoft Ltd might have overlooked this prudence concept regarding income. (Lynn, 2004) Even if the income elements are expected in the normal course of operations of the firm, a degree of judgement and probability need be attached in making the final conclusion on whether or not to include that income or else the turnover shall be overstated if that income does not materialize. Such items may include doubtful debts, exaggerations of the useful lives of some plant and equipment, etc. Apart from the probability of earning the income so anticipated, recognition as to whether that income should be able to be measured reliably should also be taken into account. Income recognition practices require that income should be measured reliably and with certainty. And if Isoft did not make reasonable estimate, then the whole items of income should have been excluded from the financial statements all together. However they should have included/shown the existence of the income items as a footnote to the accounts. (Wood and Sangster, 1999) Also related to the measurements is the cost at which a firm records its expenses which will have a direct influence to the recognized income. Isoft might have understated their reliability and expenses which is not prudent Another principle of income recognition is that of distinguishing revenue incomes from capital gains. Revenue incomes are those incomes generated from the principle income generating operations of the firm whereas capital gains are those gains made as a result of investments and or even disinvestments. Isoft might have included such capital gains as: Proceeds from sale of assets and Gains on disposals of plant and equipments in its income statements thus overstating revenue. This is a fundamental error that normally arises as a result of poor accounting knowledge on the side of accountants. The income recognition practices stipulate that only revenue incomes should be recognized in the income statements, capitalizing the capital items. 1 It should also not be forgotten that revenues should be matched with cost/ expenses incurred in realizing that income. Isoft did not employ clear cut-offs in apportioning of income and expenses to various financial problems. For instance, they might have wholesomely recognized a given income say rental income, some of which might have been rent in arrears for prior periods for previous debtors for earlier years making good their payments this year. For this case, Isoft should have only recognised rental income that pertain the current

Revolution of 1912 in China Research Paper Example | Topics and Well Written Essays - 500 words

Revolution of 1912 in China - Research Paper Example Much of the pandemonium and chaos resulted due to ineffective and failed attempted of the Qing Dynasty to modernize China in terms of female participation in politics and fulfilling the requirements of the Railway Protection Movement which concerned those Chinese people who were against the decision of the Qing government to nationalize railway development projects and transfer their control to foreign banks. Also, the decision made by the Qing government to mobilize imperial troops in an effort to oppress the people who were behind the Railway Protection Movement and the Movement for females political participation finally culminated in overthrowing the imperial rule, backfired on the Qing Dynasty itself because this action stimulated many other revolutionaries too who went ahead with their aim and never looked back (Reynolds 164). This much is clear from the historical accounts that the 1912 Chinese Revolution began as a consequence of a large number of internal systematic disorders which rapidly got out of hand due to which a great number of revolutionaries got murdered by the imperial troops but still a great many other revolutionaries went on to ensure the death of the imperial ruling system. Actually, the revolutionaries were of this mental approach that the imperial government was doing nothing potent or significant to modernize China in accordance with the international standards rather it was keeping China from progressing rapidly into a powerful economy giant on the world map. It was with this intention of modernizing China that the revolutionaries became fearless to openly oppose the Qing government and stand up against various atrocities committed by the imperial troops with the result that 1912 became the birth year of the Republican era. The Qing government headed by the last imperial ruler Puyi m obilized imperial troops against revolutionaries because people in large number in different states began disregarding Puyi and

Bshs305 R2 Ethical Scenario Essay Example for Free

Bshs305 R2 Ethical Scenario Essay Read the following scenario: Shannon is a juvenile probation officer with the Department of Juvenile Justice. Recently, she covered her coworker, Janet’s client load, while Janet was on vacation. Shannon met with several of Janet’s clients. After meeting with clients, she discovered a pattern in which the clients would report that they have not seen Janet in 2 to 3 months. However, the case files reflected face-to-face contact with all of her clients, despite what her clients stated. When Shannon investigated further, she found that the client notes were all at the same day and time, which is unlikely. Further, several of Janet’s clients needed referrals for counseling, but Janet never completed them and has not followed up to ensure her clients are receiving the necessary services. Janet is a close friend of Shannon. Shannon does not want to get Janet in trouble but realizes something must be done. Answer, in a 75- to 100-word response, each of the following questions: 1. What are the ethical issues involved in the scenario? Human service professionals are obligated to provide high-quality service to their clients. Most codes of ethics indicate that the helper’s first responsibility is to enhance and protect the client’s welfare. One of the ethical standard is the human service professional’s responsibility to clients. Standard 2: â€Å"Human service professionals’ respect the integrity and welfare of the client at all times. Each client is treated with respect, acceptance, and dignity†. Unfortunately in this scenario Janet failed to respect her clients’ welfare. She not only had issues of breaking several ethical codes she literally failed her moral responsibility. 2. What client rights are involved in the scenario? The client has a right to actively participate in their treatment plan. They are privy to view their personal chart which would show them the fabricated notes of the helper. The system failed this client and the client is able to request for a new helper. Although the client has a right to a professional disclosure statement as to see the qualifications of his helper, chances are this helper would not disclose their unethical behavior. 3. What, if any, client rights were violated? I feel the clients rights were violated by the misguided treatment of the helper. The client was not treated with dignity, respect or integrity. They were violated in a as â€Å"helpers are ethically obligated to provide quality services†. Also the helping professional is committed to helping clients develop to the best of their abilities. The helper was not even servicing the client and in that aspect the client has been violated on several different levels of ethical codes. Ethical Decision Scenario BSHS/305 Version 2 2 4. How you would use the ethical decision-making model to address or resolve the situation? First of I would identify the problem which are two issues, first one is the clients are not receiving necessary services. Second issue is Janet lied on legal documents. I would review the ethical guidelines and consult with a co-worker as to how I should proceed with the probable course of action. I would then select the course of action and follow through with my obligation to assure clients receive due services and I would make sure Janet does not make this mistake again. I would report Janet’s actions to my supervisor and hope Janet understands that I am just doing my job.

Acoustic Cryptanalysis of RSA and Its Counter Measure

Acoustic Cryptanalysis of RSA and Its Counter Measure Prof. J P Agrawal Saurabh Sharma Siddharth Gupta ABSTRACT Acoustics has come up as a new vulnerability in the field of information security. The RSA encryption algorithm, although h very hard to break mathematically, has been broken recently by using acoustics and power analysis of emanations. Acoustic Cryptanalysis is the side-channel attack which targets implementations of cryptographic algorithms. The cryptographic algorithms are quite secure at the mathematical level, but inadvertently leak secret information through signatures in power consumption, electromagnetic emanations, timing variations, and acoustical emanations. This paper presents a software based countermeasure which is based on application of specific mitigation techniques to ensure that even if there is leakage of information it would bear minimal useful information. INTRODUCTION Acoustic cryptanalysis is a form of side channel attack that aims at deriving the private key in a public key cryptography system using acoustical vibrations of a laptop. A side channel attack is basically an attack that gives attacker an additional channel of information about the system, the noise generated by computers is one such potential channel other channels include keystroke acoustic emanations, acoustic emanations from printers, power analysis via the USB port and timing attacks. Side channel attacks can only be performed on public key cryptography system because the encrypted text i.e. ciphers text depends upon the text that is encrypted. So while decryption the cipher text produces a unique acoustic spectrum which helps the attacker to extract the key. In this case we put our emphasis on a different source of computer noise i.e. vibration of electronic components like capacitors and transistors in the circuit of the CPU. These acoustic vibrations are related to the system activity since the amount of power drawn from the CPU depends upon the operation which is performed. As a study case, we will focus on the GnuPG (GNU Privacy Guard), a cross-platform, open-source implementation of the OpenPGP Standard. We will demonstrate a key extraction attack that can extract 4096-bit RSA secret keys when used by GnuPG running on a laptop computer by analyzing the vibrations generated by the computer during decryption of chosen cipher texts. RELATED WORK Analysis of acoustical vibrations is relatively a newer practice commonly used in military context such as identification of vehicles through the sound signature of their engine. Similarly computer programmers monitor the functioning of their systems by listening to sound generated by mechanical components. Some of the successfully implemented experiments involving side channel attacks include : à ¯Ã¢â‚¬Å¡Ã‚ · Electromechanical ciphers. à ¯Ã¢â‚¬Å¡Ã‚ · Keyboard acoustic emanations. à ¯Ã¢â‚¬Å¡Ã‚ · Acoustic emanations from printers. à ¯Ã¢â‚¬Å¡Ã‚ · Power analysis. à ¯Ã¢â‚¬Å¡Ã‚ · Power analysis via the USB port. à ¯Ã¢â‚¬Å¡Ã‚ · Timing attacks. THE EXPERIMENTAL SETUP (A) laptop on which the decryption is being performed (B) Brà ¼elKjà ¦r 4190 microphone capsule mounted on a Brà ¼elKjà ¦r 2669 preamplifier held by a flexible arm. (C) Brà ¼elKjà ¦r 5935 microphone power supply and amplifier, (D) National Instruments MyDAQ device with a 10 kHz RC low-pass filter cascaded with a 150 kHz RC high-pass filter on its A2D input (E) laptop computer performing the attack. Here, the microphone power, amplification and some filtering are done by an integrated, battery operated Brà ¼elKjà ¦r 5935 microphone power supply. After a self-built 10 kHz RC low-pass filter cascaded with a 150 kHz RC high-pass using capacitors and resistors, A2D conversion is done by the compact, USB-operated National Instruments MyDAQ device. The MyDAQ device captures at 200 K sample/sec. The Brà ¼elKjà ¦r 5935 amplifier is limited to a frequency of 100 kHz. OBSERVING THE ACOUSTIC LEAKAGE 1. Distinguishing various CPU operations We can distinguish between various operations performed by CPU by analyzing the low bandwidth leakage of acoustical emanations. Our analysis begins by taking into account simple operations like: HLT (CPU sleep), MUL (integer multiplication), FMUL (floating-point multiplication), main memory access (forcing L1 and L2 cache misses), and REP NOP (short-term idle). We concluded that these operations exhibit a unique frequency spectrum on execution. 2. Distinguishing various code lengths These acoustical emanations can also determine the length of loop being executed. For example the leakage produced by a code executing 10000 ADD instructions in an infinite loop will have a different acoustic spectrum than a program executing 20000 ADD instructions in an infinite loop. 3. Leakage source The observed acoustical emanations are not caused by the rotation of the fan, hard seeks or audio speakers as it is verified by disabling these components. Rather it is caused by the capacitors and resistors in the power regulation circuit of the CPU. The precise source of the emanations is difficult to characterize, since it is different in every machine and it is typically located in hard to reach places. Acoustic localization is also difficult due to mechanical coupling of capacitors and resistors and because of acoustic reflections due to other components. PERFORMING THE ATTACK The attacker sends an encrypted email to the target machine. This email when received by the target machine undergoes the process of decryption so as to extract the data that has been sent. The email which is sent involves sending a chosen ciphertext, it cannot have any random data in it. The data which is sent via the email has to be a specially crafted ciphertext. Through this attack we try to get the ‘q’ i.e. one of the prime factor of the key ‘n’. Enigmail provides an integrated graphical user interface and handles e-mail encoding and user interaction; the actual cryptography is done by an external GnuPG executable. Received e-mail messages are decrypted upon the user’s request. In addition and by default, Enigmail automatically decrypts incoming e-mail messages. Thus, an attacker can send a suitably-crafted e-mail message to the victim, containing a chosen ciphertext. When this e-mail message is fetched by the target computer, the attacker observes the acoustic emanations during decryption, and obtains a bit of the secret key. The attacker then sends additional e-mail messages, until all key bits are recovered. If the messages are backdated or made to look like spam messages, they may even go unnoticed. But this doesn’t affects our attack as it will still be decrypted by the email client. Choosing the ciphertext q is a 2048 bit number q2048 q2047 q2046 q2045†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ q2 q1 GnuPG always generates RSA keys in which the most significant bit of q is set, i.e., q2048 = 1. Considering we know the first i-1 bits of q e.g. i=4 , we know q2048 q2047 q2046 =110 Now we need to find the next bit of q , which can be 0 or 1 So , we create a ciphertext with first i-1 bits equal to that of first i-1 bits of q, the next bit 0 and the remaining bits to be 1 q2048 q2047 q2046 0 111111†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.11111 Recording the emmisions We use our experimental setup to record the acoustic emissions that are created during the decryption. Placing the microphone with respect to the laptop body has a large influence on the obtained signal. Laptops have cooling system for heat dissipation. It has a fan that requires large intake of air and some exhaust holes. Also, there are other holes and gaps for ports such as USB, Express Card slot, SD card reader, and Ethernet port. Any of these ports can be used as a position for the microphone. Typically, the best microphone placement is near the Ethernet port or the fan exhaust vent. We record the sound using the LABVIEW software. We compute the sliding-window Fourier transform of the trace, yielding a sequence of spectra, and then aggregate these spectra by taking the median value of each bin. (The use of median effectively rejects temporally-local outliers, such as transient spikes.) The spectrum is truncate to the frequency range of interest (determined manually). Extracting the key The most significant bit of a prime number is always 1. Using this fact we create a desired ciphertext and obtain the power frequency templates for 0 and 1. Thus, if the attacker were to have two spectrum templates describing the leakage of zero and one bits, he could classify an unknown signal by checking the similarity between it and the templates he has. Concretely, in our case a template is a vector of real numbers describing the signal power at each frequency bin. The classification is based on computing the correlation of the Fourier spectrum of the leakage with the two templates. Recall that q is chosen to be a prime such that its most significant bit is always set to one. Moreover, this information is known to an attacker. Thus, obtaining an example of a leakage of a one bit can be done by measuring the leakage resulting from the decryption of g2048;1. Obtaining an example of a leakage of a zero bit is more tricky. This is because the attacker does not know in advance the location of the first zero bit in q. However, this problem can be easily avoided. Consider any number l such that q 2048 1). Notice that the reduction of l modulo q is equivalent to computing l q and will cause the bits of the result to be random thus achieving a similar spectrum as the sound of zero bits of q at the beginning of the attack. After this we compare the data acquired with the templates of 0 and 1 and the output of the comparison gives one bit of the q. Then this attack has to repeated 2048 times to get all the bits of q. These templates are updated dynamically in the matter of 20 bits. After receiving the acoustic spectrum of every attack bit we try to match the frequencies with the ones in the predefined templates. Whenever we get a matching frequency we check it’s corresponding value for power if this value is in range according the given threshold of the template we classify the bit as 0 or 1. By repeating this same procedure to attack every bit we obtain all the 2048 bits of prime q and in turn find the key. COUNTER MEASURE Cipher text randomization : One countermeasure that is effective in stopping our attack ciphertext randomization. If we have a cipher text c, instead of decrypting c immediately what we can generate a 4096 bit random value r, compute re and then decrypt re* c and multiply the result by r^-1. Since ed = 1 mod (n) It does not stop the attacker from extracting the key but it masks the original key so that even if the attacker is able to extract the key he doesn’t has the correct key. In implementation we have used the random library of python. Using this library random.randint(range) generates a random integer which can be multiplied to the value of cipher text and it changes the acoustic spectrum of the ciphertext which masquerades the original key. Why software based countermeasures are better than hardware based countermeasures? Enforce a proper layering can seem to be an effective countermeasure. Unfortunately, such low-level physical leakage prevention, is most of the times, impractical due to the significantly bad cost vs. security tradeoff because of the following reasons : (1) Suitable manipulation at the higher levels can amplify any leakage remnants, similar to what we do in our chosen-ciphertext attack (2) Low-level mechanisms try to protect all computation, even though most of it is insensitive or does not induce easily-exploitable leakage (3) Essential performance-enhancing mechanisms produce leakage as an inevitable side effect.

Maine’s Commercial Lobster Industry Essay -- Business Essays

Maine’s Commercial Lobster Industry Summary Scientists predict a major population crash of Maine lobsters in the near future, due to over-harvesting, increasing demand, and a lack of successful regulatory measures reflecting such factors. The attempt to introduce various policy measures creating more limited access to the resource has been largely ineffective due to the unique ecological, economic, and social characteristics of the state. Further complicating the issue is the matter of thriving lobster populations during recent years when other marine wildlife populations are experiencing severe losses along the same region of the eastern seaboard. This paper examines the conflict between lobster fishermen, scientists, and policy makers regarding attempts to work toward a more sustainable lobster fishing industry. Introduction The issue of Maine lobster fishing is an ideal case illustrating the challenge of the "tragedy of the commons", since the lobsters belong to no one until caught. They have been harvested commercially in New England (the "birthplace" of the nation’s fisheries) since the 1800’s. At that time, they "were so plentiful they could be caught by hand or, with less hazard (because the average lobster was so large), with a gaff, a pole with a large hook stuck in the end" (Formisano, 13). Since the early 19th century, the industry adopted more efficient techniques (such as the use of lobster "pots", or traps, and boats that could carry lobsters over longer distances) to capture more lobsters faster. This led to a significant population decline by the late 1800’s, prompting the first lobster regulation (prohibiting the harvesting of egg-bearing females). Lobster populations remained relatively st... ...Globe 4 Mar. 1995: 14 Larabee, John, and Richard Price.

Comparing Wilfred Owens Poem, Dulce et Decorum Est and Stings Song, C

Comparing Wilfred Owen's Poem, Dulce et Decorum Est and Sting's Song, Children's Crusade Is it really sweet and fitting to die for one's country? This may seem glorious to some, but to those who have studied World War I and its terrible consequences, this seems a lie. The poet Wilfred Owen was a participant in this war, and wrote the poem "Dulce et Decorum Est" ("It is sweet and fitting [to die for one's country]") to his poet friends about the voracity, hopelessness, and futility of war, and the desperate plight of the soldiers involved. Almost seventy-five years later, the popular artist Sting worried about the world in which his son was growing up, a world in which older, experienced adults took advantage of innocent children to increase their own power. Using World War I as a comparison to his own time, he wrote the song "Children's Crusade" about these scheming, power-hungry people. Both these poets describe a war in which children were abused, controlled by other's selfish wants. Although Sting mainly uses strong allusions to describe the soldiers' loss of innocenc e, Owen's poem uses jarring, tangible images of reality that are emotionally more universal. As in other effective poetry, Sting uses strong language to convey the world's cruelty toward the innocent. He describes the soldiers in the war using the phrases "Virgins with rifles" (3), "Pawns in a game" (5), "Marching through countries they've never seen" (2). These phrases appeal to parental nature and sense of decency. "Virgins" suggests not only a feeling of inno-cence, but a feeling of virtue about to be lost. Sting uses the phrase "the flower of England, face down in the mud" (11), giving us a beautiful, fresh image to symbolize these young soldiers. He t... ...s a general anti-war feeling, which is only one of the points that form his argument, instead of a feeling for the plight of the children of his day. The theme of heroin addiction remains unknown to most. Sting does wield effective images, as does Owen, but as Sting's allusions remain unknown, Owen's tailoring to basic human emotions makes us regret the soldiers' loss of innocence.

Banning Smoking

Utilitarian holds that actions are justifiable if they result in the greatest possible happiness for the greatest number. As such, every human action can be said to be based upon this principle. However, there are instances where the society has accommodated practices that have proved to result in the greatest amount of harm to the greatest number of individuals. The most notable of such practices is public smoking. Smoking is not only irritating to the non-smoker but also harmful to the smoker.Research indicate that in America alone, smokers consume close to five hundred billion cigarettes per annum with more than four-hundred thousand deaths every year being attributed to this consumption (Slovic, 2001). With this regard, the society has every reason to invest all its energies in making sure that this practice is stopped since it is the single most preventable cause of premature death in many countries. As such, the society, through its most powerful institution, the government, is justified in not only banning public smoking but smoking in general.The World Health Organization predict that the number of deaths as a result of tobacco smoking will rise from four million people to ten million by the year twenty thirty (World Health Organization, 1997). In other words, if smoking is not banned, many individuals are going to lose their lives. There is no doubt that tobacco possess serious health risks. Anecdotal evidence of possible harms from this habit begun to be gathered shortly after it was introduced in Europe even though it was until the eighteenth and nineteenth century that physicians started publishing observations of serious life threatening hazards (Proctor, 2004).It was during this period that cancer of the mouth, nose and lips became associated with tobacco snuff. In France in the year eighteen fifty's, a physician by the name Etienne-Frederic Bouisson discovered that the majority of his patients suffering from cancer of the mouth were pipe smokers (Shephard, 1982). In Berlin, Rudolf Virchow also reported the same observations shortly after (Ibid, 234). By the end of the century, cancer of the lips, tongue, mouth, jaw, nasal cavities and pharynx were so common to cancer specialists that medical students wrote widely on the topic-then famously know to physicians as â€Å"Smokers' cancers† (Cortyl, 1897).Despite these inherent dangers, the society has continued to tolerate this silent killer. However, it is the responsibility of the government to protect its people from exposure to any dangers. With regard to this, many governments have failed. The practice ought to have been banned immediately after the first reports but this has not been the case. Actually, tobacco consumption increased in the late nineteenth and twentieth centuries with the invention of machines that could roll thousands of cigarettes per day (Viscusi, 1992).Coupled with the invention of safety matches, the habit quickly became popular. Instead of the government considering the health consequences of the habit, they quickly recognized the drug as a source of tax revenue. This has continued into this period with the result of furthering the use of the drug. However, some states in the United States banned the use of the drug as they recognized the reality of its dangers but the bans became lifted in the 1920s. During this period, there seemed to be much ignorance among the majority population with regard to the actual consequences of tobacco smoking.As such, the governments of the time may be excused on their treatment of the issue. In recent times though, there has been a stream of significant developments concerning the understanding of tobacco smoking and its harmful consequences. More understanding have been achieved with regard to secondary smoking and the consequences on the fetus when a pregnant mother engages in the habit. Very surprising and disturbing findings concerning the observed impacts of smoking or nicotine depend ence on twelve to thirteen year olds after days or weeks of light smoking (DiFranza et al, 2000).It was also discovered in the recent past that tobacco companies have been concealing the risks associated with smoking in their attempt to lure young people into smoking. All over the world, the manufacturers and merchants of tobacco have put their own economic interests above the health and lives of a million consumers to whom they sell their products. It is known that all these tobacco products contain nicotine which is unquestionably the element that is responsible for the most persistent and widespread drug dependence. There is no doubt about the fact that tobacco kills.It accounts for one death in every ten seconds (Slama, 1995). The majority of the victims die in their prime life and if the trend continues, as have been projected by the World Health Organization, tobacco will account for one death after every three seconds. The habit did not come as a product of chance. It has bee n furthered by effective marketing policies of the industry that have been applied in many countries. The consumption of tobacco is expensive in the long run, not just in terms of human health but also in terms of finance.Even with the short term benefits of the tobacco industry in mind, the net loss that is being suffered every year by the world community as a result of smoking is estimated at two hundred thousand million dollars (Stratton, 2001). This is not a small amount of money and if it could be harnessed, it would be enough to double the current health care expenditure in the developing parts of the world. However, it is the responsibility of the health care sector to create awareness on the actual dangers of tobacco use. Since tobacco is an international commodity, the war against it must therefore be worldwide.Public health is one of the sectors that has been worst hit by the habit. With this regard, the habit directly or indirectly impacts on the national budget of many c ountries. The problem affects every section of the society and every age and every single member of the society faces its grave consequences. It is thus the responsibility of the government to make sure that every single member of the society of protected from death that can be easily avoided. The major reasons for the call to ban tobacco are not founded on empty grounds. They have been driven through the centuries by the concrete evidence on its health effects.It is amazing that regardless of the centuries of research evidence and findings concerning the dangers of the drug, many countries still treats the issue with less seriousness. Cancer has been rated among the deadliest diseases. The world is trying to find ways of countering this condition but has turned its back on the actual causes. There is numerous evidence that indicates that smoking causes cancer and thus, there is absolutely no way that the society will pretend to fight cancer without addressing such issues as banning smoking.The rise of lung cancer and coronary heart disease that were once rare was noticed in the twentieth century and an attempt to explain such increases revealed that smoking was among their causes. However, it would be wrong to assert that the medical findings and reports were understood by the public and in situations where they were published, the tobacco industries countered such claims with assurances on the safety of smoking, at times using such reports to convince the consumers to change brands.Going by the utilitarian principle, there is no doubt that all the arguments supporting the ban of smoking should be treated with much sensitivity as the health of real human individuals is at stake. The human race does not need any further proof as to the harms and dangers of smoking and thus, every government should ban the use of tobacco so that a healthy society is realized. Tough measures should be taken against the tobacco industry as they blatantly deceive the majority into death in the name of making profits.In the mid twentieth century, individuals involved in tobacco industry were quoted as saying that they would quit the business if it was established that it poses serious health risks to the smokers. Almost half a decade later, even with enough evidence that smoking is dangerous to ones health; the industries are still alive and making millions of shillings while the majority perish. Instead of being in the forefront of informing its consumers of the dangers, the tobacco industry has tried every conceivable deceit to cover up the dangers and win over more consumers.This responsibility of protecting the citizens from the harmful effects of tobacco can thus not be entrusted in the hands of the business people but in the hands of the most superior institution of the society, the government. The government would thus do much justice to its citizens by banning smoking. References Cortyl, J. (1897) Du Cancer des fumeurs. Paris: Henri Jouve, (Translated by Edmond Gwan). Proctor, R. (2004).

Physicians Clash over Medical Ethics in Death Penalty Cases Essay

The news clipping is mainly about the dilemma doctors face. They are trained to save people. They did not choose their profession to punish law-violating citizens. Specifically, this topic has been given hype by Dr. Marc Stern who quit on his job of being the head doctor in the state of Washington’s prison whose responsibilities included maintaining the lethal injection table in order for the next death sentence. In the past several years, according to the article, medical ethics and death penalty has clashed. There are a number of instances in the past where doctors bailed out of the execution causing delay in the death penalty; case in point: Michael Morales. The article also stated that the problem does not stop here. This ethical dilemma against professional participation needs careful and further study. Capital punishment and justice would be difficult to serve if all doctors are concerned about ethics. Experts went as far as predicting capital punishment could end because of this ethical issues. Ethical dilemma The whole article is about ethical dilemma. Doctors do not want to continue participating in capital punishment (overseeing death penalties) as this poses ethical issues for them. Most of them belive the punishment is cruel and unusual. Also, doctors are trained to save lives and not to end it. Personal thoughts on the matter I understand that being an object to end another person’s life when one is trained to help save it could have severe impact on one’s conscience. The human world has become civilized enough over the course of history to preserve one another. It is even more emphasized in a doctor’s profession where preservation of mankind has been his chosen field and career. However, if all doctors feel this way, I can see the nation revolting. Without a trained professional in the death sentence chamber, there is no way an execution will happen. I can foresee various forms of protests because somehow, justice must be served according to the laws of the state. The person in death sentence was found guilty of an offense that demerits him his life. The family and friends of his victim/s have turned into the law for support to the injustice done to them. The law cannot fail these people because doctors cannot do their state-given responsibilities. There must be some doctors out there that are willing to do the job. I am not saying that the state must find conscienceless professional so that the death penalty can still be observed. There must be some doctors in the field that understand their moral obligations and their obligations to the state. Like it or not, the prosecution must be finished. They cannot let the convicted criminal die in the hands of non-professionals nor can they let the families and friends of the victims live in injustice.

Determination of Dissolved Oxygen in a Water Sample Essay

To find out the oxygen content of a water sample by adding MnSO4 and alkaline KI into the solution. Mn2+ was oxidized into Mn3+. Then Mn3+ was reduced back into Mn2+ and I- was oxidized to I2. The solution was titrated against sodium thiosulphate solution and the oxygen content could be calculated. Result Trial 1 Trial 2 Final burette reading (cm3) 19.26 38.42 19.82 38.35 Initial burette reading (cm3 0.10 19.50 0.74 19.82 Volume of Na2S2O3 added (cm3) 19.16 18.92 19.08 18.53 Data being used for calculation Calculation No of moles of Na2S2O3 used = 2S2O32- + I2 –> S4O62- + 2I- No. of moles of I2 in 100 cm3 solution = = 1.1825 2Mn(OH)3 + 2I- + 6H+ –>I2 + 2Mn2+ + 6H2O No. of moles of Mn(OH)3 in 100 cm3 solution = 1.1825 X 2 = 2.365 4 Mn(OH)2 + O2 + 2 H2O 4 Mn(OH)3 No. of moles of O2 in 100 cm3 solution = 2.365 Oxygen content = 18.92 mg dm-3 Discussion Reason of filling the whole volumetric flask During the experiment, the water sample was allowed to fill with the whole volumetric flask, this is because we have to prevent oxygen from dissolving from the air into the water sample. Reason of using a magnetic stirrer When conducting the experiment, insoluble manganese (III) hydroxide was formed. It would dissolve in potassium iodide so we have to use a magnetic stirrer to speed up the reaction process. As a magnetic stirrer could stir the solution without spilling, it is very good to be used in this situation. Source of error As the manganese (II) sulphate and potassium iodide solution was added into the flask with over flowing. There will be loss of solution in this process. The chemicals added might be not enough and it will affect the experiment result. We cannot avoid oxygen in air from dissolving into the solution as the mouth of volumetric flask could still allow oxygen to diffuse in. Only one set of data could be used beside trials.

National Savings Essay

â€Å"National saving can be used domestically or internationally. Explain the basis of this statement, including the benefits to the nation of each use of its saving. † First of all, let’s understand the concept of national savings. In economics, a country’s national savings is the sum of private savings (i. e. personal savings) plus the business savings (i. e. undistributed corporate profits) and public savings (i. e. tax revenues less public expenditure). (economicswebinstitute. org, 2003) & (Wikipedia. org, 2008). So in simple words, what people save i. e. hen they avoide to consume all their income, is called â€Å"personal savings†. These savings can remain on the bank accounts for future use. For the economy as a whole, national saving is the portion of the nation’s income not used for private and public consumption. Just as for people, saving for the national economy is the act of setting some of current income aside for the future instead of spending it for current consumption. (Gao. gov, 2001). So the savings left in bank accounts are an important part of money. This money could be used by banks, which can decide to finance businesses. The amount of money used for investment depends on the deposits, which banks receive. So an increase of personal savings and/or corporate profits could increase investment. Companies which do not distribute a certain part of its corporate profits, will keep that money in bank accounts also for future business opportunities. Domestic investment could be investment in new factories and equipment, which can increase productivity of the nation’s workforce. The increased productivity, in turn, will lead to higher wages and greater economic growth over the long term. Gao. gov, 2001). So we come to the first conclusion that if national savings increase, a country through its banks could invest more in its economy and finance more projects and support the economy. In general, more national saving will increase a nation’s capacity to produce more goods and services and generate higher income in the future. (Gao. gov, 2001). This phenomenon has been seen in a couple of Asian countries, where the saving rate of households was very high like in Russia, Japan and China, which were able to industrialize quickly. It seems also that there is a close association between national savings and domestic investment in developing countries. These countries are in desperate need for cash to invest in infrastructure and boost its economy including industry, service, etc. Before going to the international market and asking for loans, these countries will first of all make use of every penny that they can find in their banks. So one of the main findings, is that national saving provides resources for a nation to invest domestically. Traditionally, there has been a strong relation between domestic savings and investment ratios. feweb. vu. nl, 2009) The question now is: will these resources be used only in the country itself or could they be used elsewhere. In a closed economy the national savings will definitely be reinvested in the domestic economy. But this is only in theory, since nowadays we can not really find a 100% closed economy anymore! There are countries that have high net saving surpluses and which need to invest it. These countries are sometimes too small to be able to offer the right investment opportunities for this huge liquidity. Countries in the Arabian Peninsula like Qatar, UAE or Kuwait are the best example. In addition, capital is getting very mobile and can be moved easily from one country to another and invested abroad. (wikipedia. org, 2008). With all that money floating around looking for an investment, it doesn’t seem that domestic savings are all that important any more. (socrates. berkeley. edu, 2011). Let’s elaborate more on the benefits of investing the national savings abroad? We agree that the sum of national saving and saving borrowed from abroad represents the total amount of resources available for investment. This investment could be used to purchase capital goods like plant, equipment, software, houses, and inventories, by businesses and governments. (socrates. berkeley. edu, 2011). So what are the benefits of investing the national savings abroad? Will this really lead to improving domestic economy and increase the wealth of the people? An investment abroad does indeed increase the nation’s wealth and will generate income. This income could be again reinvested in the domestic country or abroad. One of the very obvious examples is the economy of the GCC countries. Qatar is one of the smallest and wealthiest countries in the world. Its main wealth comes from oil and gas, which accounts for more than 90% of its GDP. Qatar invested huge billions in its domestic economy (infrastructure, refineries, ports, real estate, preparation for world cup 2022, etc). It still has huge amount of money, which could be invested strategically. It currently, invests billions of petrodollars in all 5 continents. It has bought shares in big companies in all kind of industries (oil and gas, banks, luxury, airlines, soccer etc). By doing so, it will even help other companies and countries invest in successful businesses and boost their economies. The other countries probably have national savings which are lower than the needed domestic investment. They will borrow from foreign savers (in this case Qatar) to compensate the difference. Qatar will also repatriate this money or even reinvest it. This is a way to create more wealth to Qatar and the Qatari people of the next generations. A similar phenomenon is seen in other GCC countries, Singapore or Norway which have the so called sovereign wealth funds, that move huge amount of money from one place to another searching for the best investment opportunities. National savings is beneficial for each nation,, which needs to invest in its domestic economy. It’s also important for other nations, which borrow the money in the international capital market. By doing so, they can make use of the capital flows to invest in their economies and pay back the loans. So in total the world economy is more dynamic. Huge amount of money go to where the investment opportunities are. As a conclusion, we can say that national savings and the resulting investment have huge implications on the wealth of a nation and of course on the well being of people in current and future generations.

Rolls-Royce Aviation and the Development of TotalCare Case Study

Rolls-Royce Aviation and the Development of TotalCare - Case Study Example As the paper outlines over a period of just a few years, Rolls-Royce managed to be a compliant supplier to American Airlines and found significant business success and profitability in the process. However, Rolls-Royce maintained a strong thirst for extra profit and began to assume more risk than they originally thought they could handle. Such total care packages, as that of American Airlines, required significant internal investment into labour, facilities management and even technical support in order to provide this new extended service and maintenance contract philosophy. Realising that Rolls-Royce had found success, their largest competitors began to change their own business models to reflect similar total care packages to the B2B customers. This eroded the short-term competitive advantage which had been recently held by Rolls-Royce and threatened their market share. Added to this the costs of maintaining maintenance workshops, Rolls-Royce required a new competitive advantage i n order to remain an engine sales leader in this airline industry. This paper discusses that Rolls-Royce has focused the majority of its efforts into innovating actual service delivery to its customers, but has failed to create a marketing strategy which appeals to the psychographic characteristics of its clients. The company does not understand how to utilise promotion effectively to make the sales agreements more of a client relationship which provides mutual value to both businesses. Thus, the business has lost its previous competitive edge.

THE IMPACT OF THE TRANSFORMATIONAL LEADERSHIP STYLE ON EMPLOYEE Essay - 1

THE IMPACT OF THE TRANSFORMATIONAL LEADERSHIP STYLE ON EMPLOYEE TURNOVER WITHIN A RETAIL ENVIRONMENT - Essay Example The study will measure quantifiably by use of assessment tools. The research question is: Transformational Leadership: Transformational leaders are able to inspire followers to by granting individualized attention to their followers, considering their needs and abilities, playing an especially important role in the followers† growth and development (Robbins & Judge, 2005; Zacharatos, Barling, & Kelloway, 2000). Idealized influence: A form of leadership behavior that results in leaders becoming role models for their followers. The leaders are admired, respected and trusted. Followers identify with the leaders and wish to emulate them (Bass & Avolio, 1993) In idealized influence, behaviour of the leaders is very influential and it makes the followers to walk on the path chosen by the leaders. Thus the leaders are followed willingly by the people. Inspirational motivation: Leadership behaviors that motivate and inspire followers in their work by providing a challenging work environment. Leaders provoke followers to imagine an attractive future for themselves (Bass & Avolio, 1993) Intellectual stimulation: Strategy the results in followers becoming more innovative and creative within an organization. (Bass & Avolio, 1993) The characteristic of Intellectual Stimulation in the leaders exposes his or her ability to stimulate the intellectual capacity of the people. Those who are really genius and their intellectuality and knowledge is definitely a blessing for the attainment of the organizational goals then the leaders motivate such people to use their intellectual potentials for the growth of the organization. Individualized consideration: Individualized consideration is also one of the characteristics of the transformational leaders.

Code of Ethics - Research Paper Example The issues have always been whether to disclose such information and to whom. For instance, is it proper to place critical loggers on devices on the network to capture all that the user types? Or say so as to see all that is shown screen capture programs those are some of privacy ethical issues that have been of concern. The other ethical issue has been promising more than they can deliver or even taking advantage of client’s ignorance to charge more fees through data manipulation. Today, IT organization can install technology to make client’s network more secure but not very secure in reality. Yet there has been the dilemma of whether to replace the present firewall just to have more billable hours. Some firms promising more than they can actually achieve to gain reputation. The final loyalty has been connected to loyalty. IT organizations with contacts for multiple clients have ethical issues to deal with. For example, should they obtain information about one of their clients that can directly affect the other client, where should their loyalty

Relational Data Model - Assignment Example The attribute "is leader" should be removed from the table Candidate because this information already exists in the table Party. It is possible to get to know if a Candidate is leader of any party with looking through references to leaders in the table Party. .. First_name Middle_name Last_name address gender date of birth Party Pk_id Fk_leader name address date established Candidate Pk_id Fk_electorate Fk_party First_name Middle_name Last_name address gender date of birth is leader Second normal form (2NF) further addresses the concept of removing duplicative data: Meet all the requirements of the first normal form. Remove subsets of data that apply to multiple rows of a table and place them in separate tables. Create relationships between these new tables and their predecessors through the use of foreign keys. (Chapple 2005) So, personal information, such as name (first, middle, last), address, gender, and date of birth can be taken apart into separate table Person. It also should have a primary key named Pk_id. Then tables Elector and Candidate should reference to it via secondary (foreign) key Fk_person. Therefore there are 5 tables in the relational database schema for the 2NF: Person Pk_id First_name Middle_name Last_name address gender date of birth Electorate Pk_id unique name number of registered voters Elector Pk_id Fk_electorate Fk_party_vote Fk_candidate_vote Fk_person Party Pk_id Fk_leader name address date established Candidate Pk_id Fk_electorate Fk_party Fk_person is leader Third normal form (3NF) goes one large step further: Meet all the requirements of the second normal form. Remove columns that are not dependent upon the primary key. (Chapple 2005) The attribute "is leader" should be removed from the table Candidate because this information already exists in the table Party. It is possible to get to know if a Candidate is leader of any party with looking through references to leaders in the table Party. There's no attributes that are not dependent upon the primary key.

Case study ( Criminology ) - Essay Example This is not the first ethical case against Judge Jones as in late 2012; he was involved in an investment fraud case and was federally indicted. The consequences that time were suspension with pay and the case is still in the trial stage. Even though in this article only the Judge’s unethical behaviour has been mentioned, the prosecutor also had unethical conduct. She allowed the Judge to go ahead with hearing her cases and even helping her with case reassignment which she knew was wrong both ethically and criminally. Both parties (judge and prosecutor) were aware of the conflict of interest their romantic relationship presented to their work relationships but yet they simply were ignorant about it. They instead chose to use their romantic involvement and power of the black robe to give an upper hand to the prosecutor in the cases as well as prevent her from getting overworked hence the reassignment. The Judge romantic relationships or not holds a position in office where he is supposed to uphold equality, fairness and integrity not to mention ethics. In this case, he used the same office to break all the above mentioned virtues instead of upholding them all because of a romantic involvement with an officer of the court. Their behaviour set a bad example, creates mistrust and damage the confidence of the public towards law officers and the justice system in general. There are several measures which can be taken to prevent a repeat of the unethical behaviour like the one witnessed in the above case or even of other unethical behaviour likely to be manifested in the courtroom. The first of these is to prohibit ant romantic involvement between colleagues in the justice system unless they do not share the same court like Judge Jones and the prosecutor. This is as a way to avoid a repeat of the behaviour of the judge and encourage fairness as opposed to favouritism. The other way is to be conducting regular background and updated information on

Assignment - Zara CaseQuest - Research Paper Example The management at the company understands that the industry is dynamic and many factors continue to drive the change including customer needs and supply. However, supply is second to customer demands. The top management holds that the company must provide what the market demands and not vice versa (Bower, 2002). Zara has various opportunities and resources that would help the group meet its goals in the process of satisfying clients. The company maintains close management of with tight running of the process of production. To achieve this, Zara maintains both manufacturing and design processes in-house. The only exception is having strategic partnerships situated next to the head offices. Across Europe, the company keeps more than eighty percent of its production in-house with Spain having the least at fifty because of being close to the headquarters. Furthermore, the company enters into agreements with local manufacturers to strategically chase the clients appearing elusive. The agreements help in timely delivery of products as well as services. The company maintains flexibility by designing and producing more than twelve thousand new products to the market every year (Casadesus-Masanell, 2006). This is in addition to the benefits emanating from proximity. Application of these strategies makes the work of chasing to achieve their targets besides satisfying consumer needs. Value chasers are intangible and tangib le in terms of benefits received by stakeholders. From the tangible perspectives Inditex that owns Zara operates a net margin of slightly more than eleven percentile both in the market capitalization and operational activities. The working capital in terms of its net is healthy running more than one hundred and thirty-three thousand Euros. The exemplary performance in the financial sector demonstrates the prowess of Zara to run business in the industry. Within four years up to the turn of the century, the

Relationship amalysis paper - Essay Example Perhaps the constant communication that we have nurtured over the months could be responsible for the harmonious relationship that we have had. Essentially, H and I have been good friends since we first stepped into the same room. This actually means that even though we have had difficulties in our relationship at given occasions, we have always injected concerted efforts to make the relationship successful. Since H and I share the same room but not the same course, we rarely spend time together unless it is a weekend or in occasions where both of us are free at the same time. With this in mind, it is worthy to note that our relationship had had its successes in the same measures it has had its failures. Speaking of failures, it is important to note that H and I have had our fair share of communication problems in our relationship. Essentially, H is an international student meaning that he studies English as a second language. In this respect, there is always communication breakdown due to some elements of language barrier. Since H is very fluent in Chinese and not eloquent in the English language, we had had to seek a third party for interpretation of certain phrases and concepts. In the spirit of improving on this, H and I have resolved to incorporate more of sign language in addition to him registering for English classes that would lead to improvement in his spoken and written English. Besides the challenge of language barrier, I have to confess that my friend H is high-tempered and had poor listening skills. This has really hampered our relationship in the sense that sometimes he misconstrues what I say to him and this has particularly led to great confrontations in the past es pecially considering his bad temper. His poor listening skill has always landed my relationship with him into the murky waters in the sense that we almost broke up our relationship in the last two months. I have tried to improve on this challenge by minimizing the level

Case Study Example With the Freemium Pricing Strategy in place, it was obvious that the company’s user base would definitely increase. The strategy worked effectively in that Dropbox managed to grow from at least 4 million Dropbox users in January 2010 to more than 200 million users by November 2 years later. In as much as the company never revealed its exact revenues, it was reported by an industry analysts that the company made more than $400 million by 2012. Five years after it was launched, it can be reported that Dropbox was valued at more than 4 billion dollars. This means that the company benefited from the strategy. Alternatively, the company managed to secure a large share of Dropbox users especially for the cloud storage. This therefore enabled the company management to switch its attention to corporate customers. First, the strategy led to overcrowding with minimal competitors. Alternatively, getting users was somehow tough because of bureaucratic delays especially in making them integrate the services. There is also the notion that the freemium strategy would end being a costly affair for the company. It was feared that the strategy would leave the company with thousands of freeloaders and higher operating costs. It was also difficult to get individuals pay since most mainstream users were not used to paying for the services. Another challenge of this strategy is that the company might suffer from value perception of the services. The fact that the basic package is free, most users might have the perception that any other version that company offers has little value. Lastly, issues with competition are common. After the success of the freemium strategy, Houston started to target the corporate customers directly. Whereas the consumer Dropbox version started at only $120 per year, the business type was estimated to cost more than $800 on a yearly basis for users. Termed as the Dropbox for Business version, the strategy featured

Plato Analysis Essay Example for Free

Plato Analysis Essay Platos The Republic centers on a simple question: is it better to be just than unjust? In answering this overlying question, Socrates outlines the ideal city and how justice is a virtue of that city. From there, he characterizes justice as a virtue of the soul. It is while he is discussing the soul that Socrates begins to define the different types of souls. Rather than comparing and contrasting each soul, Plato quickly jumps into contrasting the tyrannical soul with the aristocratic soul ? the most unjust with the most just. In Book IX of Platos The Republic, Socrates describes a man in an awful state asserting that the worst of souls is the tyrant. This accurate assertion can be seen through the consideration of not only the tyrants personal characteristics but also the negative ______ he contributes to the city. In Book VIII of Platos Republic, the five types of people are presented in parallel to the fives types of regimes. The most inferior of the five regimes is tyranny. Correspondingly, the tyrannical soul is then the most inferior person. Socrates examines the steady decline from one regime to the next, starting with the fall from aristocracy to timocracy when factions arise between auxiliaries and guardians. This decline comes because of injustice and the spirit of the auxiliaries not abiding by the edicts of reason. Further decline due to an excess of desire and the degradation of spirit ultimately leads to tyranny. This is the most wretched of all the regimes as the tyrant is the most wretched of souls. Book IX of The Republic begins with a story of two young men whose lives take opposite paths. The first is raised in a home more Spartan than Athenian, born to a parsimonious father who honors the money-making desires while despising the ones that arent necessary but exist for the sake of play and showing off (572c). The son rebels against his austere upbringing, and revels in the company of subtler men who delight in the pleasures of the world (572c). However, because the young man has been brought up to abhor such worldliness, in the end he chooses a middle path ? neither illiberal nor hostile to law ? having become what Plato describes as a man of the people (572d). This introduction is important, because Plato uses the young man previously described to contrast the second. The second man is perhaps the son of the first, raised in moderation, to appreciate both the diligence of work and the joy of pleasure. When the same influences, friends, and ideas that changed his father begin to work on him, this young man does not have the inner moral courage to chart his own path. With his father urging moderation and his friends encouraging irresponsibility, the young man is torn between the two. Herein lies the downfall of the man ? the dread enchanters and tyrant-makers who espouse reckless pleasure-seeking realize that they will not win him over with continued persuasion, so they seek to make him a slave to his own desires (573a). Plato calls these desires love, but lust may be a more apt description (573b). Having now become a drone, the young man is imbued with desire to satisfy the temporal passions that bring momentary pleasure (573b). This desire drives him insane. He has madness as his bodyguard, and runs amuck, eliminating those whose own decency contrasts with his own lack thereof, killing them out of shame. The tyrant is characterized as the worst of souls because of his personal attributes that are detrimental and undesirable to any man. Drunken, erotic, and melancholic, he lives solely to satisfy the passions and desires that run rampant in his mind (573c). This man does little good by himself or his fellowmen, and, if given the opportunity, would become the most terrible of rulers. Plato defines this man to be his tyrant and describes him as the most miserable person in society. Socrates and Glaucon characterize the person ruled by lawless attitudes as enslaved, having the least amount of control to what he wants. The tyrant is full of confusion and regret, fearful and poor, with an insatiable appetite (577c-578a). To any human being, it would be least desirable to become a person as described above who is never satisfied. The greatest control an individual can obtain is control over their own thoughts and desires. Without this control, a person is miserable and relies on the outside world to fill his appetite. To illustrate the idea that a tyrant is simply one whose passions are out of control, Plato compares the tyrant to a drunken man. Just as a drunken man has a tyrannical spirit, so a man drunk on his own lustful desires has the same (573c). The tyrannical soul is seen as enslaved because it desires satisfactions that solely depend on external circumstances. As long as these desires continue to consume the tyrant and are never completely satisfied, the tyrant is least able to do what he wants. By virtue of not being able to do what he wants, the tyrant is full of confusion and disorder. This man is in an awful state and lives only in misery. By showing the development of the tyrant from undisciplined childhood to irrational adulthood, Plato shows his reader the warning signs that accompany such a person. He describes the despots of the ancient world for what they were: lustful men whose bodily appetites reign over their personal lives and the societies unfortunate enough to be at their command. Socrates explains that the only thing worse than the tyrannical soul is the tyrannical soul who goes public and becomes the political tyrant (578c). Socrates continues, The man who is mad and deranged undertakes and expects to be able to rule not only over human beings but gods, too (573c). With this phrase, Socrates begins to show why the reader should be wary of the rise of a political tyrant. He describes how a tyrants rule is bad for those he rules over. Having gotten the idea that he should rule over both men and gods, the tyrant uses this power, once obtained, to satisfy his selfish desires. Feasts, revels, parties, courtesans, and everything else of the sort, are hallmarks of his reign (573d). Such living, however, rapidly depletes his income and resources, and he is then forced to obtain resources from others which consequently becomes to the city. The tyrannical man can only give so much to the people of the city. He will therefore enlist them in necessary and just wars to continue his popularity and to account for the poor economy. These just wars serve to perpetuate the continual need for a tyrant. Because the tyrants actions displease those who helped set him up, he must gradually do away with them until he is left without a friend or foe. Socrates contrasts this to the work of a doctor. A doctor is seen as helpful and needed because he takes off the worst of the body and leaves the rest (567c). However, the tyrant does the opposite, taking off the best and leaving the worst. This is a necessity for him to rule; consequently, he hurts the city. The tyrant, slave to his love, or personal passions, becomes a tyrant over others. He begins to find those with means and seeks to deprive them of it, usually by force. He is addicted to his desires, racked with pains and aches when he cannot fill them (Plato, 263). No one is immune to his wild demands. He will victimize his own parents, claiming he deserves to get the better of his father and mother (574a). If they resist, they will meet the same fate as anyone else who opposes the madman. In short, his childhood of moderation has become a career of chaos. The tyrant is a slave to himself and his desires in the city. The moral of Platos argument is clear. Even a small minority of tyrants can cause trouble within a community. Plato suggests that in times of war, tyrants flock to the battlefront, volunteering their services to distant tyrants as mercenaries and bodyguards (Plato, 264). But in times of peace, they remain at home and comprise a class of lawless criminals. Thieves, burglars, cutpurses, pickpockets, temple robbers, kidnappers, all are tyrants waiting for their chance to take power (Plato, 265). Platos warning to society is to teach temperance and philosophy to the rising generation, so that they do not become tyrants and lead their city into ruin. In an age where democracy was a new and rare commodity, the threat of becoming subject to a tyrant in ancient Greece was very real indeed. Philosophers like Plato tried to discover how the tyrants of the age became so, so that they could avoid coming under their power. Having philosophically defined tyrants as evil and unjust in the realm of philosophy, Plato uses logic in Book IX of The Republic to support the assumption that totalitarian societies, like those of Athenss neighbors, suffer under the reign of such leaders. This argument will later lead to his assertion that philosophers are the best leaders a state can have. Bound by ethics and reason, philosopher-kings would ensure that society is properly educated, supremely tolerant, and, most importantly, true to the ideal of justice that Plato holds dear.

Object databases are a niche field within the broader DBMS market dominated by relational database management systems (RDBMS). Object databases have been considered since the early 1980s and 1990s but they have made little impact on mainstream commercial data processing, though there is some usage in specialized areas. When database capabilities are combined with object-oriented (OO) programming language capabilities, the result is an object database management system (ODBMS). Todays trend in programming languages is to utilize objects, thereby making OODBMS ideal for OO programmers because they can develop the product, store them as objects, and can replicate or modify existing objects to make new objects within the OODBMS. Information today includes not only data but video, audio, graphs, and photos which are considered complex data types. Relational DBMS arent natively capable of supporting these complex data types. By being integrated with the programming language, the programmer can maintain consistency within one environment because both the OODBMS and the programming language will use the same model of representation. Relational DBMS projects using complex data types would have to be divided into two separate tasks: the database model and the application. As the usage of web-based technology increases with the implementation of Intranets and extranets, companies have a vested interest in OODBMS to display their complex data. Using a DBMS that has been specifically designed to store data as objects gives an advantage to those companies that are geared towards multimedia presentation or organizations that utilize computer-aided design (CAD). Some object-oriented databases are designed to work well with object-oriented programming languages such as Python, Perl, Java, C#, Visual Basic .NET, C++, Objective-C and Smalltalk; others have their own programming languages. ODBMSs use exactly the same model as object-oriented programming languages. Advantages: The main benefit of creating a database with objects as data is speed. OODBMS are faster than relational DBMS because data isnt stored in relational rows and columns but as objects. Objects have a many to many relationship and are accessed by the use of pointers. Pointers are linked to objects to establish relationships. Another benefit of OODBMS is that it can be programmed with small procedural differences without affecting the entire system. This is most helpful for those organizations that have data relationships that arent entirely clear or need to change these relations to satisfy the new business requirements. This ability to change relationships leads to another benefit which is that relational DBMS cant handle complex data models while OODBMS can. Disadvantages: Slower and more difficult to formulate than relational. Lack of interoperability with a great number of tools/features that are taken for granted in the SQL world, including but not limited to industry standard connectivity, reporting tools, OLAP tools, and backup and recovery standards. Lack a formal mathematical foundation, unlike the relational model, and this in turn leads to weaknesses in their query support. Applications: Object databases based on persistent programming acquired a niche in application areas such as engineering and spatial databases, telecommunications, and scientific areas such as high energy physics and molecular biology. They have made little impact on mainstream commercial data processing, though there is some usage in specialized areas of financial services.[6][7] It is also worth noting that object databases held the record for the Worlds largest database (being the first to hold over 1000 terabytes at Stanford Linear Accelerator Center)[8] and the highest ingest rate ever recorded for a commercial database at over one Terabyte per hour. Another group of object databases focuses on embedded use in devices, packaged software, and real-time systems. http://shine.yahoo.com/channel/none/oodbms-object-oriented-database-management-system-basics-533483/ /************************************** Observations from a Tech Architect: Enterprise Implementation Issues Solutions by Craig Borysowich  (Chief Technology Tactician) Enterprise Technology Architect Craig Borysowich shares the challenges and achievements of enterprise solution design and more Enterprise Technology Architect Craig Borysowich shares the challenges and achievements of enterprise solution design and implementation. ..less Blog Main  /   Archive  /   Invite Peers   RSSRSS for Posts  /   RSS for Comments Previous Entry / Next Entry Some Pros Cons of Relational Databases Craig Borysowich  (Chief Technology Tactician)  posted  5/1/2008 | Comments  (0) http://images.ittoolbox.com/vt/icons/thumbsup.pngLike (0) Please Sign In or Register to like this blog. Working Share Share The relational model for databases provides the basic DBMS characteristics. In addition, an RDBMS also conforms to Codds model. Relational Database Characteristics Dr. Codd established 12 rules to which a DBMS must conform to be considered relational. DBMSs vary in the way in which they comply with these rules, however, commercial relational databases generally conform to these rules. Strengths of RDBMS Flexible and well-established. Sound theoretical foundation and use over many years has resulted in stable, standardized products available. Standard data access language through SQL. Costs and risks associated with large development efforts and with large databases are well understood. The fundamental structure, i.e., a table, is easily understood and the design and normalization process is well defined. Weaknesses of RDBMS Performance problems associated with re-assembling simple data structures into their more complicated real-world representations. Lack of support for complex base types, e.g., drawings. SQL is limited when accessing complex data. Knowledge of the database structure is required to create ad hoc queries. Locking mechanisms defined by RDBMSs do not allow design transactions to be supported, e.g., the check in and check out type of feature that would allow an engineer to modify a drawing over the course of several working days. http://it.toolbox.com/blogs/enterprise-solutions/some-pros-cons-of-relational-databases-24144 /******************************* The Advantages of a Relational Database Management System ds_0ecbc811-e864-4fed-a7c6-5a46ff28cd3fContributor By Deborah Lee Soltesz, eHow Contributing Writer Article Rating: (0 Ratings)   Email   Facebook   Twitter   StumbleUpon Add to Favorites   Print   Share I want to do this! Whats This? RDBMSs provide user access control and data integrity features. data security image by dinostock from Fotolia.com   RDBMSs provide user access control and data integrity features. A Relational Database Management System (RDBMS) is a software system that provides access to a relational database. The software system is a collection of software applications that can be used to create, maintain, manage and use the database. A relational database is a database structured on the relational model. Data are stored and presented in a tabular format, organized in rows and columns with one record per row. Data Structure The table format is simple and easy for database users to understand and use. RDBMSs provide data access using a natural structure and organization of the data. Database queries can search any column for matching entries. Multi-User Access RDBMSs allow multiple database users to access a database simultaneously. Built-in locking and transactions management functionality allow users to access data as it is being changed, prevents collisions between two users updating the data, and keeps users from accessing partially updated records. Privileges Authorization and privilege control features in an RDBMS allow the database administrator to restrict access to authorized users, and grant privileges to individual users based on the types of database tasks they need to perform. Authorization can be defined based on the remote client IP address in combination with user authorization, restricting access to specific external computer systems. Network Access RDBMSs provide access to the database through a server daemon, a specialized software program that listens for requests on a network, and allows database clients to connect to and use the database. Users do not need to be able to log in to the physical computer system to use the database, providing convenience for the users and a layer of security for the database. Network access allows developers to build desktop tools and Web applications to interact with databases. Speed The relational database model is not the fastest data structure. RDBMS advantages, such as simplicity, make the slower speed a fair trade-off. Optimizations built into an RDBMS, and the design of the databases, enhance performance, allowing RDBMSs to perform more than fast enough for most applications and data sets. Improvements in technology, increasing processor speeds and decreasing memory and storage costs allow systems administrators to build incredibly fast systems that can overcome any database performance shortcomings. Maintenance RDBMSs feature maintenance utilities that provide database administrators with tools to easily maintain, test, repair and back up the databases housed in the system. Many of the functions can be automated using built-in automation in the RDBMS, or automation tools available on the operating system. Language RDBMSs support a generic language called Structured Query Language (SQL). The SQL syntax is simple, and the language uses standard English language keywords and phrasing, making it fairly intuitive and easy to learn. Many RDBMSs add non-SQL, database-specific keywords, functions and features to the SQL language.
