online education Essays - Educational Psychology, Distance Education

Today, in our modern world, the word ?innovation? is in use almost every day. It is always something new going on in every sphere of our life. The most important innovation in education of last century was online education. There are a lot of disputing abut advantages, and disadvantages of extend education, however there are three major strengths characterizing education on the web; flexibility, cost effectiveness, and privacy. The first strength and the major one, is flexibility, and easy access to learning. Whether you are in Asia, Europe, Africa, or anywhere else e-education will always be with you (the only thing you need is the internet). Mark Kassop, the author of the article ?Ten ways Online education Matches or Surpasses, Face ? to - Face learning?, notes: The height of this flexibility may be the well-publicized eArmyU.com program?. All students are on active duty, and they belong to military units throughout the world?. In a recent class of 25 students, the participants were located in Europe, Asia, The South pacific, Alaska, Hawaii, and all Kovaleva 2 four time zones in the continental united States.(360) Also student with families or jobs do not have enough time to attend school. In this case way web education might be the only one solution. ?The advantages of online learning,? emphasizes Kassop, ?include ample opportunities for students to pursue coursework at any time that fits into their busy lives? (360). The second advantage of web learning is cost effectiveness. In the most of the countries high education is not free. The average tuition fee is depends on country, but usually very high. Not a lot of people can afford a bachelor, or master degree. In many cases young people prefer to work after high school, than to apply for college. Alfred Bork in his article at ?The Well Crafted Argument? points out: In developing countries, learning often happens only on a very limited scale because these societies cannot afford learning with the methods currently employed. Even in developed countries, the cost of learning is becoming a problem. Current systems for learning cannot adequately grow to meet society?s needs. (341) Kovaleva 3 Online education is more affordable, than a traditional ?face to face? one. Students can save money, and still get high quality education without leaving their houses. The third advantage of leaning online is ?anonymity?. A lot of students at the traditional college system are ?hiding? their points of view: somebody is shy, somebody just do not want to share theirs opinion. The online education gives students around the world to share their experience, discuss problems, and simply chart without any F2F connection. It helps a lot of people to ?open? themselves, and to be social. Mark Kassop believes that: Many online students have indicated that this is the first time they have ever ?spoken up? in class and that they enjoy the opportunity? Many instructors have also observed that the relative ?anonymity? of online discussions helps create a level playing field for women, homosexuals, student with physical handicaps, and members of other potentially marginalized groups?.(358) Therefore we have three major advantage of web education, that helps student all around the world to have not only affordable, flexible education, but also an education that helps them to open their minds, and to be self-conscious.

Making A New Deal essays

Making A New Deal essays Lizabeth Cohen wants to prove that Chicago workers created a working class during the depths of the Great Depression. Unfortunately, the means she chooses to prove her case do not completely convince me. In Cohens hefty Making a New Deal she posits a transition of Chicagoans from ethnic, employer-loyal workers in 1920s to members of a common culture who articulated a class consciousness in the 1930s. She asserts that workers needed to overcome ethnicity before they could realize class, but then backs away from this claim. In the end, Cohens ambivalence, the rosy picture she paints of the New Deal era, and her overemphasis of class consciousness all weaken the book. The books central theme holds that ethnicity had to be overcome if working-class unity was to be attained. Cohen plants seeds of theoretical discontent within this framework that undermine her basic argument. For instance, in Chapter 3, Encountering Mass Culture, Cohen argues that mass culture and consumption standardized American life in the 1920s. But then she retreats from this sweeping generalization, equivocating that the impact of mass culture depended on the social and economic contexts in which it developed and the manner in which it was experienced (101). Despite the prevalence of mass culture it did not make working-class Chicagoans feel any less Polish, Jewish, or black or any less of a worker (158). Yet Cohen shows that even as ethnic workers listened to radio programs and shopped at chain grocery stores that were not supposed to influence them (in Cohens opinion), they began to have more in common with their co-workers of different ethnicity and race (157). Either ethni city or class has to prevail here, and I am not sure Cohen knows which one she prefers. I admire Cohens effort to present a positive picture of ethnic and black cultures by presenting their resiliency, but she understa...

Changing Of Life Essay Example | Topics and Well Written Essays - 1000 words

Changing Of Life - Essay Example In these regards, there were a lot of daily tasks that I took for granted. For instance, simple things like fixing my car I never took care of, because I had always relied on my brother whenever there was a problem that was needed. For instance, I recall one incident where we were driving to visit a family friend. During the trip, one of the tires went out on our car. My brother immediately got out of the vehicle, opened the trunk, and began to change the tire. After my brother's accident, he was not able to accomplish tasks such of this. A few months after his accident we were driving to visit another individual and a tire went out on the vehicle. For an instant, I looked to my brother expecting him to jump out of the car and change the tire but instead came to realize that this time I would have to learn how. We rolled the window down and my brother explained to me the exact steps I needed to take in order to change the tire. This has I learned the process and would be able to acco mplish it in future situations. While this situation with changing tires is one incident, it reflects the large change that took place in my life after my brother's accident. Slowly, I began to learn a lot of skills that I had never had to learn before. My life had truly changed. From this point on I would no longer be able to simply watch television or engage in random past-time activities. My new lifestyle involved becoming more active in day-to-day activities. I learned to become more engaged in daily activities.

An introduction for the germination experiment Lab Report

An introduction for the germination experiment - Lab Report Example Seed germination process is comprised of several steps. First, the seed absorbs water from the surrounding environment through osmosis. Water absorbed activates enzymes, increases the rate of respiration and leads to duplication of plant cells. Secondly, the chemical energy stored as starch is converted to sugar and serves the embryo as food during the process of germination. The embryo is nourished and enlarged resulting in seed coat burst. Lastly, a root tip known as the radicle emerges from the seed and grows downwards to anchor the seed. The radicle enables the embryo to absorb water and minerals from the soil (Jirage 1). A study on the effects of treatment on seed germination will be carried out as a laboratory experiment. The experiment will involve a non-dominant maize seed and a treatment acid. The experiment will comprise three setups. The first set-up will involve low level of the acid and the second will contain high levels of the acid. The third set-up will be a control- experiment that will not involve any treatment. Pre-treating with an appropriate concentration of Gibberellic acid (hormone G A3) plays an import role in the induction of tolerance to salinity. Additionally, it helps the seed overcome the environmental stress, such as osmotic effects, nutritional imbalance and ionic toxicity. This can be achieved through strong root and shoot length that gives a response to salt stress (Jamil

Discuss the role of the motor cortex in movement. 1500 Words Essay

Discuss the role of the motor cortex in movement. 1500 Words - Essay Example The motor cortex plans voluntary actions – it helps in initiating, planning, controlling and maintaining voluntary movement of skeletal muscles, coordinates sequences of movements and relay commands to the appropriate sets of lower motor neurons to execute the desired actions. Diseases or traumas on this part of the brain have adverse effects on the patient. Presently, such diseases include Apraxia, which causes an inability to initiate purposeful learned movement in response to external commands despite the ability and desire to perform the movement, and Parkinson’s and Huntington’s disease – characterized by loss of the ability to initiate movement or stop it once initiated plus the occurrence of uncontrollable movement. Modern man, Homo sapiens, has an average cranial capacity of 1350cc far more than all his other earlier ancestors. This increased cranial capacity is credited for his higher intellectual ability over other animals and primates. The brain serves many functions in the body, from thought to emotions, waking and sleeping, respiration, memory, controlling actions just to mention but a few and can thus be considered as the central control for the whole body. Like all other living things, man also moves around in search for food, flight from danger or for pleasure. Movement is a function of muscular flexion and extension all which are under the control of the brain – except for reflexive movements, which are controlled by the spinal cord and mainly help maintain posture and balance without involving the conscious mind. The brain is divided into six main parts; the cerebral hemispheres, hypothalamus, thalamus, cerebellum and the brain stem – mid brain, pons and medulla oblongata, each of which has its different functions (Marieb, 2000). The cerebellum contains a region known as the motor cortex in the precentral gyrus that helps in initiating, planning and controlling voluntary movement of skeletal muscles. The motor cortex is further

Militant Abolitionism In 1830s

Militant Abolitionism In 1830s During the colonial era, Quakers Society of Friends had a difficult time convincing North American people that slaveholding was against Christian doctrines. However, the age of Enlightenment and the American Revolution led many Americans into fighting for slaves rights. Northern states also started a gradual emancipation of their slaves. The federal government also prohibited slavery in the Northwestern Territories in 1787 and in 1808 banned trans-Atlantic slave trade. However, despite the abolition of slavery in these two areas, antislavery agitation dropped off due to the increasing profitability of southern slavery. The birth of the Movement and its Activities The modern American militant abolition movement began in the early 1830s as a result of religious revivalism popularly known as the Second Great Awakening. Abolitionists thought of slavery as a product of an individual sin by Revivalist tenets. These tenets believed that emancipation was the only price for repentance. Later on, abolitionists realized that slavery was receiving moral support with some racial prejudice. Immediately, the abolitionists lobbied to change the nations racial discriminatory practices. Abolitionists tried to reach and convert people during the 1830s. Founded in 1833, the American Anti-Slavery Society recruited tens of thousands of members from all parts of America. The Abolitionists condemned slavery on moral grounds and pursued immediate emancipation of all slaves. National religious institutions and individual slaveholders, who were the chief targets, rejected the abolition appeals. Opponents went further to suppress antislavery agitation through enactments from the church and state. African American activists joined the new campaign. Some, like Brown, had many records of public opposition to racial discrimination in the north and the colonization movement. Fugitive slaves, such as William Wells Brown and Fredrick Douglass, provided strong antislavery testimony. However, black abolitionists encountered patronizing views and attitudes from the white abolitionists. Hence, many turned to self-help and civil rights groups, while others concentrated on separatist projects. Many women braved public disapproval and joined the abolitionist campaign. Women are known to be veterans of moral reform activities, and principles of religion and republican ideology inspired them. Like their African American counterparts, these women faced opposition within the movement. Women were first barred from the American Anti-slavery movements, but in response, they formed local organizations through which they channeled their concerns and sponsored antislavery events such as bazaars and picnics. Due to the widespread rejection of the anti-slavery program, many abolitionists changed their moral persuasion strategy. Most of them led by William Lloyd Garrison abandoned their churches. According to Garrison, churches had become hopelessly corrupted by slavery. Women participated in American Anti-slavery society after 1840. Maria Weston and Lydia Maria were among the many women who served in the groups operations and main office duties. Religious and political abolitionists also emerged in late 1830s. Non-Garrison abolitionists grouped in a new organization known as The American and Foreign Anti-Slavery Society. The abolitionists lobbied religious institutions, and by 1840, they had an organized Methodist, Presbyterian and Baptist antislavery movements. Political antislavery campaigns also intensified during this period. Abolitionists petitioned legislatures and interrogated political candidates on slavery-related issues. Antislavery Efforts before 1830 Abolitionist feelings were strong during the American Revolution and the upper south by 1820s. However, the abolitionist movement never coalesced into a militant crusade until 1830s. In the previous decade, before 1830, much of the north underwent social disruptions associated with the spread of commerce and manufacturing. Powerful evangelical religious groups arose to impact spiritual direction to the society. These preachers stressed the importance of ending sinful doings and practices and the responsibility of every individual in upholding Gods will in the society. Lyman Beecher, Nathaniel Taylor, and other preachers, on what came to be called The Second Great Awakening, organized massive religious revivals in the 1820s. This came later to be the main impetus of the resurgence of abolitionism. By 1830s, William Lloyd Garrison, Theodore D. weld, Lewis Tappan, Arthur, and E. Wright had spiritually been nourished by revivalism and had taken up the cause for immediate emancipation Conclusion The main objective of the abolitionists was to end racial discrimination, segregation, and immediate emancipation of slaves. The religious favor of the Second Great Awakening partly fuelled racial abolitionism. This prompted many people to start advocating for immediate emancipation on religious grounds. As time went on, abolitionist ideas spread in northern churches. Politics of 1830s also contributed to the regional animosity between the South and the North, leading to a civil war.

Shakesperean Clothing Essay -- essays research papers

Have you ever looked at a picture of your parents when they were your age? Or maybe your grandparents from way back when? Well, judging by how much we laugh at their goofy clothes and ridiculous shoes, not to mention the hilarious hairstyles, styles have changed a lot. We?ve gone from high waists to low waists, baggy shirts to shirts that could fit your little sister, from bellbottoms to skin-tight jeans, and from voluminous hair to straight and silky locks. Yes, style can change a lot in a few decades and if you think that's a lot of change, try going back a few centuries, to the times of Shakespeare! Back then, the women wore a lot more clothes than we do, that?s for sure! The style included a chemise, stockings (hose), a corset or bodice, a hooped skirt called a Farthingale, a roll (rowle), a stomacher, a petticoat (or a few), a kirtle, and a forepart as underclothes. For over-clothes, they wore a gown, separate sleeves, a ruff, a cloak, shoes, and a hat. I never wear that many layers. Can you imagine how warm it would be in those clothes all day in the middle of July? As f...

Social Network Marketing & Its Effectiveness

Introduction The objective of this review is to explore what the research says about social network marketing and its effectiveness. The first wave of internet revolution (web 1. 0) brought consumers e-commerce. The second wave, Web 2. 0 evolved into a much robust and interactive experience, allowing consumers to participate and share information effectively, Social network media such as Facebook, Tweeters, etc. have grown rapidly. Users are not only teens but also adults. The popularity of smartphones, hand-held tablet computers, computer notebooks also help the increase in popularity of using these sites.For instance, social net work media have replaced e-mails to become the most popular communication tools. To marketing practitioners, this wave of digital revolution cannot be ignored. More than that Web 2. 0 enable consumers to generate content and share. This change is totally different from conventional marketing, in which firms generate content or messages to bombard users and potential users (such as advertising). It is now not a question of whether a company should use digital media, but how they can maximize the benefit from the rise of these new media network.It may not mean that conventional marketing tools such as advertising will be replaced overnight, but social network media should be able to synergize conventional promotional tools. Thus, naturally the question of tracking and measuring social network media and its ROI will be asked, which will be addressed in this paper. The use of social network media in consumer marketing is well established. Its application in education, healthcare, and also in pharmaceutical promotion are also explored. Word of Mouth Marketing To begin with, the concept of word of mouth marketing is explored.Marketers recognized that the conversations among customers are powerful influence of product adoptions (Ryan and Gross 1943; Rogers 1962). Traditionally, marketers develop message to influence selective consumers (who may be early users) and these consumers help propagate the product message to other consumers. More sophisticated marketers will identify influencers in the group of potential consumers (or opinion leaders) and influence them. Thereafter, these opinion leaders can help propagate marketers' message to other consumers.In web 2. 0 err, consumers will participate in the whole marketing communication process. They will coproduce content to be shared in their chosen network. Hence, Word of Mouth model has evolved from a consumer-to-consumer process in the past to a opinion leader to consumer model, and most recently, a network coproduction model (Figure 1. ) Marketers do not only influence the selective consumers (opinion leaders) in the launch phase, but also have to monitor the process of consumer to consumer messaging.The coproduction model of word of mouth marketing is further depicted by Adrian Palmer and Nicole Koenig-Lewis. In their article â€Å"An experiential, social network-ba sed approach to direct marketing†, the authors proposed a framework of 3 elements of the social network environment – the seller, the customer and the community (Figure 2). In this model, the traditional interface for direct marketings has been between the seller and the customers, represented by the hatched area. With the introduction of the community element, the customer interacts with self-selected communities.Sellers need to interact with selected communities to achieve a variety of benefits, including spreading of positive word of mouth and gathering information about buyers' needs and preferences. The challenge is how to balance the interest of the sellers, the customers and the community, and this is represented in the overlapping area of the 3 circles. Figure 2. Direct marketing in a social network Success Factors for Social Network Sites Shu-Chuan Chu and Yoojung Kim studied the determinants of consumer engagement in social networking sites (Chu & Kim 2011).Ba sed on literature review, the authors identifies 5 determinants – tie strength, homophily, trust, normative and informational interpersonal influence as important antecedent to eWOM behavior in SNSs. Tie Strength Tie strength refers to â€Å"the potency of the bond between members of a network† (Mittal et al. 2008, p. 196). Example of strong tie strength is family members, whereas weak tie strength is colleagues. Strong tie were more likely to be activated for the flow of referral behavior. The hypothesis is that SNS users' perceived tie strength with their contacts is positively related to their engagement n eWOM behaviors in SNSs.Homophily Homophily refers to the degree to which individuals who interact with one another are congruent or similar in certain attributes (Rogers & Bhowmik 1970). The assumption is that people with simailar characteristics, such as age & character may come together to form community. Hence, the hypothesis is that SNS users' perceived homoph ily with their contacts is positively related to their engagement in eWOM behaviours in SNSs. Trust Trust is defined as ‘a willingness to rely on an exchange partner in whom one has confidence' (Moorman et al. 1993, p. 82).In todays popular SNS, users share information with their own real network and thus, significantly increase the level of trust. Therefore, the hypothesis is SNS users' perceived trust in their contacts is positively related to their engagement in eWOM behaviors in SNSs. Normative influence Normative influence refers to the tendency to conform to the expectations of others. It affects attitudes, norms and values (Burnkrant & Cousineau 1975). The hypothesis is that SNS users' susceptibility to normative influences is positively related to their engagement in eWOM behaviors in SNSs. Informational influenceInformational influences, on the other and, denote the tendency to accept information from knowledgeable others and be guided in product, brand and store sear ch (Bearden et al. 1989; Deutsch & Gerard 1955). The hypothesis is that SNS users' susceptibility to informational influences is positively related to their engagement in eWOM behaviors in SNSs. These factors were tested in an on-line survey of the college students on their 3 operationalized engagement: opinion seeking, opinion giving and opinion passing. The findings of the study are: Tie strength is positively associated with eWOM behavior.On the other hand, a negative relationship was found between homophily and eWOM in SNSs. Trust is found to be positively impact engagement with eWOM. Normative and informational influences are important for the engagement, but informational influence in opinion giving is not determined. Implications: The results from this study suggest that advertisers must take social relationship factors into account and develop personalized marketing communications strategies to fulfil SNS users' needs. Insight into Network Co-production of Product Messaging That marketers may not have full control in the product messaging in social etwork marketing, Kozinets, de Valck, Woinicki & Wilner studied a mobile phone launch campaign using social network media (blogs) (Kozinets, de Valck, Woinicki & Wilner 2010). 83 bloggers were seeded with a new mobile phone and their blogs were monitored for 6 months. The bloggers were selected based on their traffic on their blogs. There is no obligation for the bloggers to write or not write. This study gave detailed analysis of the posts and provide good insight and lessons learnt from a commercial program used in social network media. The study found that bloggers can be categorized based on their character style.For instance, in the study at least 4 types are identified, 1. citizen journalist, 2. loving mother, 3. satirical exhibitionist, and 4. the making-ends-meet professional blogger. Four narrative strategies are identified (Figure 3) – evaluation, embracing, endorsement and explanation. Whic h strategy to be adopted depends on the blogger's character, the governing norm in the community and the commercial element in the WOMM. The study found that the motivation for consumers to participate in the co-production of WOM are more complex and culturally embeded, shaped by communal interests and communicative orientations and charged with moral hazard.WOM communicators demonstrate their need to balance inherent commercial-communal tensions while being consistent with the character elements of their ongoing narratives. It is also found that WOMM message and their attendant meanings will be altered by communicators in ways taht are attuned to a range of different individual and communal factors. The managerial implications from the study are the followings. Firstly, managers should pay attention to not only the quantity (so-called amplification by advertising professional), but also quality of the consumer-generated messages.Secondly, consumers that play the role of communicato rs should be further explored, classified and devloped. Thirdly, managers should proactively explore the norms assococaited with the communication network. Marketer also need to rethink whether some degree of control must be imposed in a WOM campaign. For instance, in the current study, that bloggers are free to write and even disclose their relationship with the firm can generate negative WOM and distrust in the community. More important this study also suggests that managers have an opportunity to encoruage particular narrative stategies that may be ideal for their product.Figure 3 Social Network Marketing vs Traditional Marketing? Studies shown that social network marketing (word of mouth marketing) and traditional marketing work synergistically (Onishi & Manchanda 2012; Trusov, Bucklin & Pauwels 2008). In a Japanese study, how blogs and advertising interact during product launch in movie and cell phone categories were studied. The study found that advertising will stimulate blog ging activities during product pre-launch, and effect is less apparent post launch (Onishi & Manchanda 2012).In another study (Trusov, Bucklin & Pauwels 2008), electronic word of mouth (eWOM) programs of a social network site were compared with PR programs (media appearance and Events) in terms of the effectiveness in generating new sign-ups. The founding is that eWOM is more effective than media appearance and events. However, it is also observed that eWOM and PR work synergistically. The studies also showed that blogging and eWOM effects are more long-lasting. The effectiveness of Social Media MarketingIn the article by Hoffman and Fodor (Hoffman & Fodor 2010), the authors attempted to address the ROI metric of social network marketing. As social network sites are now easily measured by search of your brand's blogs or data mining, quantative measurement seems to be ppssible. Some people may want a simple direct short term sales against direct costs. The authors caution whether thi s is a suitabke measurement of social network effectiveness. Nevertheless, we know that Social network marketing can substituted traditional marketing.As traditional marketing such as TV advertising is expensive, by allocating a certain amount of promotional budget to digital marketing can definitely reduce cost and achieve more or less same results. Another benefit of social network marketing is the improvement of market research by direct communicating with users and thus, significantly saving the amount of market research costs. To meaningfully measure ROI of social media marketing, the authors suggest to begin with identifying the objectives of a particular social marketing campaign in order to take into consideration of different nature of social network media (figure 4).In short, brand awareness, brand engagement and word of mouth effect can be measured.

revolutions of 1848 essays

revolutions of 1848 essays The revolutions of 1848 occurred in almost every country of Europe. The revolutions left all of the countries involved wondering why it had happened and just exactly what it was that had happened. People were revolting against the extensive government control that dominated their lives. The people who determined the laws of a constitutional monarchy were virtually all nobles and upperclassmen. The people wanted to be represented equally so that they would not be treated unfairly concerning matters such as taxes, punishments, and employment. The revolutions of 1848 were not successful in the fact that nothing good came of them, but they were successful in the sense that some changes were made in favor of the revolutionists. The goals of the revolutionaries of 1848 were to get better lower-class representation for the peasants. They were tired of being treated so poorly when they were the ones that supported the country the most of all classes. The first hint of a revolution being near was the period of famine that racked Europe in 1846. The prices of grain were driven up due to its dearth. The famine of Europe affected everyone, including the poor, workers, employers, and investors. Likewise, people all over the continent were crying out for a more democratic nation. The people of Europe began to revolt, following the example set by the French Revolutionists and the revolts in Poland in 1846. They demanded freedom of speech and freedom of assembly, saying that both were inalienable rights of men. Parisians protested against their governments repressive acts. The people of Prussia were building barricades in Berlin as a way of protesting their government. There were protesters all over Europe trying to get away from repressive matters and unequal opportunities for employment and government offices. Very few of these issues were changed with all of the revolts. One thing that the revolts did create was the creation of a gap...

Explanation of Homomorphic Encryption

Explanation of Homomorphic Encryption Abstract Homomorphic encryption has been created to improve services in cloud computing. The encryption will enable organizations to use cloud computing in analyzing and mining data. Public cloud providers need the intervention of homomorphic encryption to promote security on the access of information.Advertising We will write a custom research paper sample on Explanation of Homomorphic Encryption specifically for you for only $16.05 $11/page Learn More Researchers have suggested that this system has the ability of analyzing information without decrypting (Geiselmann Steinwandt, 2002). It shows that homomorphic encryption develops a key that performs mathematical operations on encrypted data and enables the same results on unencrypted information (Kalai, 2003). Therefore, the connection between functions on unencrypted data and operations to be done on encrypted information in defined as homomorphism. Studies have showed that this invention would be used to provide security on the Internet because many people access this media to seek information. The growth of technology has made people consult the Internet using cloud providers such as Google and Yahoo. Communication Homomorphic encryption assists companies to encrypt their database of emails and post them to the cloud. The cloud assists the company to use the stored information to confirm how its workers are collaborating. Initially, when a firm is installing the new system, it may be able to run a few basic programs. However, as it continues with the system, it can apply it to all other operations. This indicates that after the data has been stored in the database, it can be downloaded without exposing any information (Lipmaa, 2005). The access of information on the Internet may be dangerous because other competitors may be able to access policies that the firm plans to initiate to dominate the market. Companies have classified information which should not be accessed by everyone. Therefore, when competitors are able to get such information, they can use it against the company. The company should device a safety device which will protect data from other cloud users. Some systems break down, and, as a result, people are able to get information stored. In this case, homomorphic encryption protects such information from being reached as the system is being reset. Firms face competition from other companies, which offer similar goods or services (Limpaa, 2005). These competitors will work to outshine other so as win customers and dominate the market. The company may use the information acquired to develop strategies so as to fulfill its interest.Advertising Looking for research paper on programming? Let's see if we can help you! Get your first paper with 15% OFF Learn More The above information shows that homomorphic encryption promotes business by safeguarding the firm’s data. Homomorphic encryption enables programs to be effectiv ely evaluated so as produce encryption on the output. The system has an enormous impact on outsourcing of private programs such as cloud computing. During the invention period, the system was challenging because people did not believe in full homomorphic encryption. It was supporting evaluation of an unlimited number of additions but could offer functions to one multiplication. The homomorphic encryption scheme is given as c =pq + m where c symbolizes the cipher text, m the marked text message, p is the key and q the random number (Mulmuley Sohoni, 2002). Addition, subtraction, and multiplication described the function of homomorphic encryptions. This system is efficient in arithmetic because it involves small numbers, which could be solved in parallel. Arithmetic performance is improved with the application of Residue Number System, RNS. Security Homomorphic computations are designed to function on data without exposing or accessing actual modulus so as to ensure security of data in programs. It promotes the confidentiality of data by adding confusion to the modulus. This indicates that, in cloud computing, homomorphic encryption transforms the modulus randomly through multiplication. Gentry (2010) indicates that a fully homomorphic encryption scheme was announced in 2009. This scheme supported evaluation of low polynomials on encrypted data (Endsuleit, Geiselmann, Steinwandt, 2002). According to Craig, the security of this scheme overlooked two problems, which were low weight sum problems and worst case on ideal lattices. The cipher texts in Gentry’s scheme did not depend on the length of the operations that evaluated encrypted data. Instead, it relied on the number of operations the computation time performed. Homomorphic computation promotes confidentiality by distributing the program to various clouds, and it verifies that the outcome of the cloud is exactly valid (Canetti, Krawczyk, Nielsen, 2003).Advertising We will write a custom rese arch paper sample on Explanation of Homomorphic Encryption specifically for you for only $16.05 $11/page Learn More This shows that homomorphic encryption prevents clouds from tampering with the module. It follows by developing a strategy to each cloud, which can reduce the impact of security because of collusion. This shows that researchers at every level were working on how to protect data from being accessed by unnecessary people. Cloud computing involves a network of machines to a single program for efficient monitoring and significant service delivery. However, these machines are independent in their operation. Therefore, homomorphism promotes confidentiality of information. It protects them from being reached by other machines on the Internet, and protects the security of data. Last but least, homomorphic encryption can make the computation on multiple systems so as to compare results. The client can use several ways to make sure that the cloud does not acces s the module set because it can affect the confidentiality of the program. References Canetti, R., Krawczyk, H. Nielsen, J.

Offshore Drilling in Alaska Essay Example | Topics and Well Written Essays - 1500 words

Offshore Drilling in Alaska - Essay Example On 31th March, 2010, President Obama projected to open vast stretches of American coastlines to natural gas and oil drilling, much of it for the initial time, in an ostensible bid to win political backing for climate and energy legislation. However, that idea stimulated distress among environmentalists and warmish support from Republicans remained a tight set back by the enormous oil slick generated in April 2010. â€Å"The commotion, at the Gulf of Mexico drilling rig, blasted and sank off the coast of Louisiana, killing 11 workers and left four others in critical conditions† (U.S. 26). A pipe leak a mile deep discharged out what the government ultimately estimated to be nearly 5 million barrels of oil in the Alaska, making it the biggest accidental spill in world history (U.S. 27). In response to this spill, the government put in place suspension on deep water gas and oil drilling, a step that arose as a setback to the oil industry and infuriated Atlanta communities reliant on offshore drilling for income and jobs. Later, the government announced that it indented to end the suspension and issuing new guidelines that tighten standards for blowout preventers, well design, safety certification, worker training and emergency response. In the end of 2010, pulling back more from Mr. Obama original plan, the government rescinded its decision to enlarge offshore oil exploration along the Atlantic Coast. The drilling would continue under suspension for those zones for at least the subsequent 7 years, until sturdier safety and environmental standards remain in place. However, drilling would continue in western and central Gulf of Mexico, though, under a fresh set of safeguards initiate after the deadly oil spill and BP explosion (U.S. 34). In April, last year, a year subsequent to BP spill began the far - maligned federal agency accountable for policing Atlanta offshore drilling had reshaped with a strong new director. â€Å"It now had an awkward new title (the Bureau of Ocean Energy Management, Regulation and Enforcement) and a bundle of stricter safety regulations† (U.S. 8). The agency was endeavoring to put several distance between themself and the industry it controls. However, even those running it accepted that it would be for years before they could create a robust regulatory system able to minimize risks to workers and the proximal environment while still allowing offshore exploration. In November 2011, the Barrack Obama administration announced its planned 5 - year strategy for offshore oil and gas drilling, which calls for launching new areas in Alaska but blocks development along the West and East Coasts. The plan upset environmentalists but fell far petite of what the oil production and its Congressional devotees demanded (U.S. 8). Some of the pros of the oil drilling in Alaska include noise pollution. Seismic waves sent on the ground tell analyzers where oil reserves may be lying. This noise pollution may cause whales a nd other cetaceans, like dolphins, to strand themselves on shore. The drilling also brings with it noise pollution to the surrounding neighbors. As we have seen in the paragraphs above, drilling comes with a high probability of oil spills. The oil spills has such widespread effects in an ecosystem that it is unmanageable for humans to remedy, though, we can try to clean up the polluted environment

Electronic medical record implementation in correctional facilities Assignment

Electronic medical record implementation in correctional facilities - Assignment Example A carefully designed and well managed continuous monitoring program may effectively transform an otherwise static electronic medical records technology. Monitoring also helps in determining emerging risks and barriers during the implementation process. This offers fundamental information to the relevant change managers and the corrective facility officials to identify risks, take mitigations actions, and make credible decisions with regard to the operation of the electronic medical records. While implementing electronic health records in correctional facilities, two main methods will be employed to monitor the change process. These are the issue log monitoring and surveys. Issue log monitoring One approach to monitor the implementation of electronic health record is to employ the issue log or to make an extra log for concerns. Concerns in the case of electronic health records refer to the matters that are not directly actionable or solvable. Taking that the staff and the implementing teal are meticulous in reporting record keeping and information technology related matters, the frequency and severity of issues may signal an emerging problems. This is especially so when sudden increases in a certain concern are observed in a single area. If the management or the change facilitator compares the issues arising or issues log with the risk register that identifies risks associated with electronic records change, certain aspects in the issues log will stand out and may be construed as increasing risks potential. This calls for a contingency plan to be instituted to deal with the problem that may arise (Schwalbe, 2006). Surveys Surveys in form of questions to monitor fundamental elements of electronic health records offer a structured manner to monitoring organizational change risks. In this manner; the change implementation team makes a assessment premeditated to draw out feedback from the organization and the staff on their perception of the project. Survey also hel ps to identify the organizational change factors that may contribute to the success or failure of the implementation effort. By carrying out surveys and assessment at various intervals and comparing results from assessment to assessment, the implementing team can swiftly establish areas that necessitate more consideration and intercession. While making and conducting an assessment, it is essential to represent extra time and cost to the electronic records technology, various benefits needs to be considered. One benefit is that gathering time and cost information forces regular and system review of the project as it is perceived by the impacted employees and patients. As the analysis is employed from time to time, it can be enhanced and reused (Schwalbe, 2006). Additionally, the analysis can speedily gather feedback from a large part of the organization, enhancing the visibility of the electronic records implementation project and minimizing unexpected or unwarranted reactions. The r elationship between the organization’s related processes, systems, and personal or professional roles and their affect on EHR The provision of electronic health records in correctional facilities is an increasingly involving exercise. Complexities arise due to the complexities of correctional facility services and systems, as well as the various processes and relationships. Electronic health r
