Essay about The Pros and Cons of Outsourcing - 3739 Words

Introduction This paper is a general overview of outsourcing. It explores when to outsource and what advantages and disadvantages a public manager may face when deciding whether to outsource. I have chosen references to support this text that are both academic and colloquial. Indeed it was a discovery to learn that Outsourcing had become a well-developed academic area of study. My prior study of the subject revolved around personal conversations and non-academic magazine articles. It may be interesting to note that an internet search using key words, privatization + government in both Yahoo and Dogpile failed to bring up a specific government agency devoted to outsourcing or privatization. In the private sector there were†¦show more content†¦Examples: everything from construction of aircraft carriers and management of nuclear weapons facilities to provision of landscaping services. Thus outsourcing/privatization may be considered broad encompassing terms while, contracting out may be a variant and subcategory in the sense that the goods and services may still be owned by the parent organization. For example, The Navy may have contracted out XYZ Iron Works to build an aircraft carrier, but the Navy still owns it. The Post Office on the other hand is a quasi-independent organization, formerly run by the government but is now privatized. At other times the privatization/contracting out distinction is more apparent. The researchers found that successful state and local government reform plans seek to eliminate or privatize functions that are not essential. Where privatization is not practical, they introduce competition by contracting out the service.3 In other words, a task is either wholly turned over to a private organization to run or is given partly to a private agency to run for a set period of time. I will explore both of these issues, i.e. contracting out and privatization/outsourcing as many of the features of both overlap in terms of the decision making of public managers.

Oscar Fingal O Flahertie Wilde - 1533 Words

n Dublin, Ireland, Oscar Fingal O’Flahertie Wilde was born on October 16, 1864. His two parents were William Wilde, a Victorian doctor, and Jane Francesca Elgee, an artistic revolutionary. They also gave birth Willie Wilde and Isola Wilde, who eventually died at the age of ten. Overall, Wilde grew up in a family full of intelligence and creativity. Because Wilde was raised with many intellectuals in his environment, he had the advantage of an advanced education beyond his years. As an eleven year old boy, he attended Portora Royal School in which he showed great, scholarly achievements. He found his interests in Greek subject matters and also earned awards as a full-fledged scholar. At a adolescent age, he was able to pursue his career as a young scholar by attending Trinity College, where his interests peaked in the classics. He then received a scholarship to Magdalen College of Oxford in 1874. During this time, Wilde went through a great metamorphosis in which he had found himself. Through his professors, he found beliefs of truth and beauty; that art should be valued and adored for its own sake. However, Professor Pater became the most prominent influence to Wilde’s development and pursuit of his sense of self. He emphasized that individuals should lead a life of sensual pleasure, and Wilde wanted to do this through a rtistic means. By 1848, he graduated with a completed degree and had written a poem called â€Å"Ravenna†. With this poem, Wilde won the Newdigate Prize,Show MoreRelated A Comparison of Oscar Wilde and Dorian Gray Essay1330 Words   |  6 PagesComparison of Oscar Wilde and Dorian Gray      Ã‚   One novel that stands out as literary masterpiece is The Picture of Dorian Gray by Oscar Wilde.

Climate Change Is The Single Biggest Environmental And...

Climate change is the single biggest environmental and humanitarian crisis of our time. Our Earth’s temperature is climbing at an alarming rate. Earth s average temperature has risen by 1.4 °F over the past century, and is projected to rise another 2 to 11.5 °F over the next hundred years. The planet is seeing the devastating effects of a warmer earth; warmer oceans, melting ice caps, and rising sea levels. As these and other changes become more pronounced in the coming decades, they will likely present challenges to our society and our environment. When the sun’s radiation reaches our atmosphere, some is reflected back into space and some passes through and is absorbed by the Earth. This causes the surface of the Earth to warm up. Heat released from the Earth is radiated outward and absorbed by greenhouse gases in the atmosphere. This process prevents heat from disappearing into space and keeps Earth warm enough to sustain life. Some human activities, such as burni ng fossil fuels, intensify the warming effect by releasing additional greenhouse gases into the atmosphere. These gases include carbon dioxide, methane, and nitrous oxide. Carbon dioxide is considered a relatively weak gas; however, so much of it is released that it has the largest impact on the enhanced greenhouse effect. Carbon dioxide is primarily produced by the burning of fossil fuels in cars, power plants, and factories.

Diversity, Diversity And Inclusion Are Common Design Elements

For the successful execution in innovation, diversity and inclusion are common design elements in five theories: absorptive capacity, actor-network, agency, attachment, and attribution theories. Through these five theories, I would like to share my thoughts about why diversity and inclusion are common elements in five theories, which make a huge difference in innovation. Here are the details: Absorptive capacity supports diversity and inclusion that recognizes the value of new knowledge, assimilates it, and uses it toward achieving innovation. In order to be innovative, we need to help our team better absorb and use new knowledge to accomplish our innovative goals. Through diversity, absorptive capacity greatly impacts the ideas of technological change, which grows a company’s profitability. For example, 70% of Google’s engineers are Black or Asian American. This diversity led it to the No. 1 market share holder in the IT Software industry, by achieving one of the highest profitabilities. In absorptive capacity, diversity increases new business opportunities that come from diverse people. A diverse approach using absorptive capacity has both positive and negative effects. It increases numbers of new ideas. At the same, it takes a long time to communicate, understand, and trust each other in a team. Staying within a comfort zone is easy and does not take time because we are used to doing that, without thinking.

Distributed Systems Transactions Parallel -Myassignmenthelp.Com

Question: Discuss About The Distributed Systems Transactions Parallel? Answer: Introduction Webb's Store is the retail store located in Australia. Webb wants to grow and furnish their business activities and thus for better marketing growth, they have planned to migrate to the cloud. They are in a dilemma whether the cloud computing will help them the benefits or not (Beck, Hao Campan, 2017). They are also concerned about how they should adopt the cloud in a secure way. The report will showcase the security concerns that are associated with the move of Webb from the SQL server to IaaS cloud architecture. The benefits, as well as the issues correlated with the database and cloud architecture, will be discussed in the report. The backing up of data, retrieval and storage of data in the cloud will be elaborated in the report. The recommendations will be grandstand as well and this recommendation will help Webb whether they should adopt the cloud technology or not, what advantages they can get as a result of this cloud technology. Security deployment to protect this migration of database to IaaS instance Webb if adopt cloud technology they will have to face the issues like data breaches and the data breaches generally occur by means of hijacking ones accounts, illegal access to APIs, and malware and worms attack (Shufeng Xu, 2012). These are the breaches are carried out by the hackers. For this reason, to protect the database from illegal access, following steps must be followed. Proper follow-through of the network: The database admins must be aware of the data where Webbs data will be stocked, the database admin must label those data so that those can be acquired from the database whenever needed (Azam et al., 2013). Network information security: A set of rules and regulations must be set for each employee and the customers also their access to the database must be set to a certain extent (Dinh et al., 2013). Security Intelligence techniques and procedures: The Event Management techniques and the Security Intelligence should be incorporated to detect any faults residing within the defence system (Sadooghi et al., 2017). Along with that suitable cryptographic technologies must be used to add more security to the system. Benefits and issues related to deployment of these security measures Benefits of security measures To become secured from the DDoS attack- The cloud security solutions is responsible to secure both the database and the system from DDoS attack and thus via security measures, the authenticity and the authorization can be assured. Security assurance of the information- Cloud security solutions are capable of securing Webbs data from all kinds of threats and risks. iii. Regulatory compliance- The cloud security solutions assist Webb to monitor the advanced cloud infrastructure, in this way the financial data residing within the database can be secured (Varia Mathew, 2014). Suitable solutions- The server can get crashed and this can mishaps can be averted by cloud solutions escalation. Later Webb can scale back to cut down the huge cost while the huge cloud traffic gets over. Enabling 24x7 services- Webb can communicate with the customers all the time throughout day and night 24x7 with the help of cloud solutions (Dillon Vossen, 2015). Cost- Webb do not have to bear extra cost for hardware and software products, they only have to pay for the cloud platform which they will hire from Amazon. vii. Integrity- The data integrity shows that data must be stored honestly and securely and since Amazon is brand name offering services to customers for a longer period of time, they can assure the data integrity solutions for sure. The major issue they will have to face that they will have to pay the heavy amount of money to the cloud vendors for ensuring the security of their office system and database (Muthui SISAT, 2013). Risks associated with migrating database to the cloud with respect to- The risks associated with the database are- Data breaches- Webb's data can be compromised if their data gets hacked by the hackers and the intruders, Webb can get into trouble and their reputation can suffer. Webb, for this reason, can heavy loss. Accounting hijacking of customers and employees- Webb's database contains the important sensitive information of the company's employees and the customers (Tsai et al., 2014). If those data get hijacked by phishing or any other means the company, as well as company's database, can be at risks. Malware attack- The attack carried out by malware, virus and the worm can make the entire Webb database susceptible to attack. The IaaS infrastructure The risks correlated with IaaS Cloud are- Misconfigure- Webb's existing hardware and software can misconfigure with the cloud vendor's framework and so they need the updated hardware and software solutions. Vulnerable issues- The Elastic Workload protector procedure by three procedures Remediate, Scan and Prioritize methods can detect the IaaS framework components which are susceptible to risks. Shadow-IT- This Shadow-IT involves the non-usage of dormant assets for a longer period of time, the usage of Amazon AWS services which is the beta mode, usage of the server which remains idle for a long time (Manvi, Shyam, 2014). In this scenario, Webb will use the cloud server provided by the cloud vendor so they will not use the database anymore which they are using right now. Thus this unused database can be a matter of concern. Communications between Webbs and their IaaS database in the cloud Webb must use the IaaS cloud architecture provided by Amazon AWS. Amazon is known to provide the best cloud solutions among all the vendors. Therefore, they can be benefitted using the Amazon web services. They will provide the required hardware and software solutions for Webb, Webb just needs to make minimum changes in their prevalent system framework and database to comply with the proposed cloud framework model of Amazon (Gai, Steenkamp, 2014). Amazon is known to cater the best cloud advanced technology solutions along with that the security benefits and Webb are sure to enjoy the features. Backing up data to the Cloud The threats and the security risks associated with backup of data are- Webb will need a strong bandwidth to both upload and download data that is how they can keep backup of their data. Webb has to keep in mind they have to spend money heavily for the fast bandwidth. The data can be compromised while it is being transmitted. iii. Also due to the breakdown of the server, there will be a chance of data loss. Storage of data in the Cloud The data if transmitted via insecure unencrypted network there is a chance of data breaches. During deployment of data in the cloud, Webb must be careful enough of the file they are storing if they are not stored properly the intruders can gain access to the important data that belongs to that file will be exposed (Manvi, Shyam, 2014). Retrieval of data from the cloud The high bandwidth is required to download files and to work upon. The data downloaded from the cloud database may contain the virus contained in the file must be checked. The following benefits that Webb can acquire are- Webb's database can be scaled to gain maximum throughput and along with that, the profitable services can be gained. As Amazon will take the maximum responsibility to maintain and update the database, so Webb will not have to think to spend on hardware and software (Manvi, Shyam, 2014). iii. The cloud security solutions will be catered by Amazon, so, once again Webb can stay safe and secure and will not have to think about the data being getting compromised. Their IaaS infrastructure Webb adopting the Amazon AWS cloud services definitely can stay ahead of their times. They can get a competitive edge. Moreover, they do not have to bear heavy expenses for the hardware and the software (Sharma et al., 2017). They just need few hardware and software changes to integrate their existing framework model to their Amazon cloud framework model. Since Amazon is a global brand they just need to trust Amazon. Their Ms SQL Server 2012 R2 cloud instance Amazon RDS for SQL server caters the facility so that Webb can utilise the capabilities of their SQL database to the utmost. The physical security must be assured to safeguard al hardware, software elements from illegal access (Dillon Vossen, 2015). The digital certificate also comes handy while question arises for the database security. Their Cloud network infrastructure Amazon is known for catering smart solutions for clouds and also the advanced security. The latest configuration system is required by Webb to enhance their business operations (Varia Mathew, 2014). The latest configuration systems include latest software and hardware components and integration is absolutely necessary to execute the apps and performs the associated tasks. Their Cloud backup and restore infrastructure Webb's data will be transacted through a secure channel over the internet thus all kind of data breaches and intruders' attacks can be mitigated with the help of Amazon AWS's advanced cloud solutions (Sharma et al., 2017). Conclusion It can be concluded from the above discourse that Webb can get immense benefits simply by switching to the cloud. The Amazon AWS has a lot to offer to Webb and the consultant Webb hire must acknowledge Web about the potential benefits of the Amazon AWS cloud architecture. Webb can get a competitive edge over others while conducting their business activities in both Australia and New Zealand. The advanced security solutions associated with Webb's switching of their SQL database to IaaS cloud has been portrayed in details in the report. The risks, threats as well as the advantages involved within the framework and the database has been explained in the report. The threats correlated with the backing up of data, storage and retrieval of data has been elaborated in the report. Also, the recommendations have been made on the procedures that Webb must follow to utilise the Amazon AWS cloud fruitfully in their premises.

The Great Gatsby, written by Scott F. Essay Example For Students

The Great Gatsby, written by Scott F. Essay The Great Gatsby, written by Scott F. Fitzgerald in the 1920s is the epitome of the Jazz Age, a phrase coined by the author himself. In the novel, Fitzgerald uses many literary elements to accurately portray the time period in which he lived including setting, characters, diction, and many symbols, which form the majority of the analytical portion of the story. In fact, many of the characters in the book double as a symbol, in order to strengthen a particular motif or theme within the novel. The most apparent, recurring and powerful theme in the book is the corruption of the American Dream during the Jazz Age. Even though many scholars believe that Fitzgerald is promoting the Dream, he is actually condemning it and what it stands for. This theme is used in conjunction with the motif of appearance versus reality to criticize further the single green light, minute and far away 25 that many Americans have strived for: financial success, fame, power and glory. Fitzgerald masterfully uses the character Gatsby to show the illusion that is the American Dream that, in reality, is an extremely corrupt and greedy practice during the extravagant and flagrant era of the 1920s. Primarily, Fitzgerald uses Gatsby to show the corruption and the greed that consumes and destroys the followers of the Dream. When Gatsby realizes that he is not able to be with Daisy in his youth because of his social class, he decides to pave his own way by climbing to her social class. Formerly James Gatz, he the sort of Jay Gatsby that a seventeen-year-old boy would be likely to invent, and to this conception he was faithful to the end 95, beginning his search for a higher social class. Gatsby is willing to give up the institution of family and his heritage in order to gain monetary wealth like many of the immigrants coming over to America to make a living. This vice of Gatsbys assist the readers negative view towards the main character and further criticizes the idea of the American Dream, because of the priority of money over family values. After his departure from Cody, Gatsby earns his money from obviously crooked proceedings. Even with his crimes not being known, it can be assumed that he is a villain and breaks existing laws. This can be seen when his party guests speculate over whether he killed a man or if he was a German spy in the war 47. This corrupt portrayal of Gatsby is confirmed later in the story through the shady character of Meyer Wolfsheim, the Jewish gambler with cufflinks made from the finest specimens of human molars 70, showing yet again the corruption that Gatsby uses to gain his wealth; whereas The Dream advocates hard work to gain your success and wealth. Although Gatsby himself is a very disillusioned man, Fitzgerald also expresses his loathing toward the American Dream by what Gatsby is actually chasing, Daisy. After Gatsby recounts to Nick his story  of past times with Daisy, Nick responds to a motivated Gatsby by declaring that one cannot repeat the past, as Gatsby is trying to do. Disillusioned, Gatsby defends his actions when he says cant repeat the past?à ¢Ã¢â€š ¬Ã‚ ¦ of course you can, attempting to counter Nicks statement. Through this quote, Fitzgerald reveals the impossibility of the American Dream, which for Gatsby, is Daisy. The followers of the Dream are mislead and will never realize their goal, the same way as Gatsby cannot repeat his past times with his dream. Later, at one of the climactic sections of the book, Daisy is forced to choose between Tom and Jay. .u2e489b10bbf62a51d67af32d2e083252 , .u2e489b10bbf62a51d67af32d2e083252 .postImageUrl , .u2e489b10bbf62a51d67af32d2e083252 .centered-text-area { min-height: 80px; position: relative; } .u2e489b10bbf62a51d67af32d2e083252 , .u2e489b10bbf62a51d67af32d2e083252:hover , .u2e489b10bbf62a51d67af32d2e083252:visited , .u2e489b10bbf62a51d67af32d2e083252:active { border:0!important; } .u2e489b10bbf62a51d67af32d2e083252 .clearfix:after { content: ""; display: table; clear: both; } .u2e489b10bbf62a51d67af32d2e083252 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u2e489b10bbf62a51d67af32d2e083252:active , .u2e489b10bbf62a51d67af32d2e083252:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u2e489b10bbf62a51d67af32d2e083252 .centered-text-area { width: 100%; position: relative ; } .u2e489b10bbf62a51d67af32d2e083252 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u2e489b10bbf62a51d67af32d2e083252 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u2e489b10bbf62a51d67af32d2e083252 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u2e489b10bbf62a51d67af32d2e083252:hover .ctaButton { background-color: #34495E!important; } .u2e489b10bbf62a51d67af32d2e083252 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u2e489b10bbf62a51d67af32d2e083252 .u2e489b10bbf62a51d67af32d2e083252-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u2e489b10bbf62a51d67af32d2e083252:after { content: ""; display: block; clear: both; } READ: Araby- Vanity EssayEventually she states, that she did love him once- but she loved too 126, and eventually choosing to flee Long Island with Tom. Through her actions, Fitzgerald shows the fleeting American Dream, the dreamer never achieving his goal, just as Gatsby never claims Daisy for his own. Daisies voice is highly significant in displaying the corrupt value of the Dream, which is solely based on gaining material goods and nothing else. After meeting Daisy at Nicks house, Nick observes how her voice held him most, with its fluctuating feverish warmth, because it could not be over-dreamed- that voice was a deathless song 93. Daisys voice here entrances Gatsby, and is the one thing that Gatsby will never stop loving about her. Fitzgerald is probably alluding to the sirens, the ancient mythical creatures that sang sailors to their deaths by captivating them with their magical voices; and thus giving a highly critical view to Daisy and her deathless voice. Further on in the novel, Nick realizes what it is about Daisys voice that fascinates Gatsby so much. It full of money-that the inexhaustible charm 115 that draws Gatsby closer to her, that is her power over him. Gatsby is entranced by material goods, like much of the population during the prosperous twenties, and Fitzgerald uses these quotes to exploit the defects of greed and materialism in his character. By developing Gatsby and his goals, Fitzgerald exposes the fantasy of the American Dream and the corruption within it. Even though millions of immigrants came to America in pursuit of economic wealth, to turn their rags to riches, nearly none of them succeeded in achieving the Dream that so many sought. The Dream is truly a dream, something that one would think of subconsciously when asleep. Monetary wealth is never gained easily and as Fitzgerald demonstrates, requires corrupt means to achieve, completely destroying the illusion that is the American Dream, the green light, the orgastic future that year by year recedes before us. It eluded us then, but thats no matterà ¢Ã¢â€š ¬Ã¢â‚¬ tomorrow we will run faster, stretch out our arms farther. . . .
