You MUST submit the assignments using the Word document(s) provided you. You may not use any other word processor, except Microsoft Word. Do not use Open Office DOCX files.

When an instructor has possession of an electronic document it is very easy to detect plagiarism. Many instructors use Turnitin assignments, which is applicable to assignments that permit cut-and-paste as this assignment. It is very easy to compare multiple copies of word documents (see link below). Microsoft provides a variety of FREE anti-plagiarizing tools. And there is a wide variety of tools that can analyze hidden information within a Word document (see sample link below). Changing fonts, margins and spacing does not do it anymore. Even when individuals try to artificially change content, a Word document contains hidden markers that may provide an audit trail to find previous authors and computer systems who have edited the document.

Fight crime. Unravel incidents... one byte at a time. http://computer-forensics.sans.org/community/papers/gcfa/computer-forensics-investigation-image-file-analysis_170 Why am I providing some of this detailed information? There are several reasons.
1) The real world exists outside this class. A student in this class must be aware of the dangers when organizations or individuals provide electronic copies to others, e.g., an email attachment.
2) The objective of this assignment is to "introduce" minimal knowledge that is required in the real world. If you do not acquire this minimal knowledge, you will significantly harm your employment, income, promotion and retention potentials. If you do not want to do the hard work, I can recommend a better alternative to plagiarism - get a new major or career plan. Perhaps you can star in a reality TV show.
3) The majority of my students will exert the effort and submit excellent assignments. I will use many of the previous tools as time permits to ensure that you do not steal their grade. I really don't understand why a student would provide a student with a copy of their assignment when they are competing in the same job market. In my class both the original author and the plagiarizer will be punished.

If you do not have a copy of WORD, you may use VMWARE VIEW (available from the RMU website) to access a virtual lab computer which contains any software needed for this course. http://www.rmu.edu/web/cms/departments-offices/administration-services/it/Pages/vmware-view.aspx NEVER STORE ANY DOCUMENTS ON THE DESKTOP OF VMWARE VIRTUAL COMPUTER. You will lose your document. It is preferable to store you documents on a local flash drive.

Since the quiz and test questions are based on your researched answers, I would recommend that you refer to any quiz questions on the assignment topics to ensure that your assignment answer is complete. Some quiz answers will NOT be provided to you unless 75% of your answers from practice attempts are correct.

A little background information. What is a DB2 Storage Group?

DB2storage groups are a set of volumes on disks that hold the data sets in which tables and indexes are stored.

After you define a DB2 storage group, DB2 stores information about it in the DB2 catalog. (This catalog is not the same as the integrated catalog facility catalog that describes DB2 VSAM data sets). The catalog table SYSIBM.SYSSTOGROUP has a row for each storage group, and SYSIBM.SYSVOLUMES has a row for each volume. With the proper authorization, you can retrieve the catalog information about DB2 storage groups by using SQL statements.

When you create table spaces and indexes, you name the storage group from which space is to be allocated. You can also assign an entire database to a storage group. Try to assign frequently accessed objects (indexes, for example) to fast devices, and assign seldom-used tables to slower devices. This approach to choosing storage groups improves performance.

Once a DB2 Storage Group has been created, DB2 must allocate storage volumes between Table Space (Volumes where tables are stored) and Index Space (Volumes where Indexes are stored.) After DB2 Storage Groups, Table and Index Spaces are designated one can define a DB2 database.

DB2® databases are a set of DB2 administrative structures that include a collection of tables, their associated indexes, and the table spaces in which they reside. You define a database by using the CREATE DATABASE statement. Finally users can create tables, indexes and other DB2 objects.

The bottom line is DB2 administrative process starts with the DB2 Storage Group, which is nothing but a simple z/FS volume. Can a DB2 Storage Group share space with use sequential and PDS data sets. Yes, but in the real world this may not be desirable

8. Data structures are elements that are required to use DB2. Using the following tables describe the following DB2 Data Structure (which is listed from most inclusive to the least inclusive). DB2 Data Structures | Description | Databases | | Storage Groups | | Table Spaces | | Tables | | Views | | Indexes | |

-------------------------------------------------

5. Compare Java Servlets versus Enterprise Java Beans. Answer =>
-------------------------------------------------

-------------------------------------------------

Using J2EE terminology a J2EE operates in a Java Virtual Machine (JVM). From an architectural point-of-view a JVM is roughly equivalent to a z/OS address space. Each JVM or address space is isolated from each other. In batch processing an address can only execute one batch program. However, CICS (a transaction manager) can execute many different CICS applications - all located in one address space. In fact, there may be multiple CICS regions (different address spaces) that may work together to provide more band-for-the-buck, i.e. scalability. However, it important to notice that in a CICS there is a CICS boss which manages the address space and executes CICS transactions.

A WebSphere JVM works the same way. Within WebSphere Application Server for z/OS, a logical application server can consist of multiple JVMs, each executing in a different address space. These address spaces are called servant regions (SR), each containing one JVM. If a servant region abends, another servant region can take over the incoming requests in a multiple-servant environment.

The Servant Region (SR) is a JVM that does the work - executes applications. These applications can be Servlets, Java Server Pages, or EJBs. A Control Region (CR) is a second type of JVM. A CR manages the servant regions. A basic WebSphere server has a least one CR (the boss) and one or more SR (workers). What makes WebSphere special as compared to J2EE is that Websphere is also designed to work with the z/OS Workload Manager (WLM) and multiple z/OS logical Partitions. The job of WLM is to automatically provide a designated level of performance. Besides adjusting paging and memory allocation the WLM can simply start another worker to get better performance, i.e., start another Servant Region.

-------------------------------------------------

-------------------------------------------------

14. In a Network Configuration, how many WAS nodes are there? Answer =>
-------------------------------------------------

-------------------------------------------------

15. What is the function of a WebSphere Node Agent? Answer =>
-------------------------------------------------

-------------------------------------------------

A little explanation to supplement the text book.
The text book indicates that a WAS Cell is of a collection nodes with a single administrative domain. This gets to be a little confusing. Is a cell another type of boss? Is a node agent another type of boss? I thought the Control Region was the boss. Yes, they are all bosses, but you need to know the "boss of what?"

Let's say that a WAS contains a SR, which contains multiple flight information J2EE applications. In a base configuration, the Control Region communicates with HTTP and routes the web application requests to the SR for execution. It is a few weeks before spring break and WLM determines we need more workers (SR). The WLM may start another SR or they may other SR on this WAS that previously started. Therefore, the Control Region is the boss of performance. The CR will route the web application request to the SR that balance the work load (the least used SR).

To continue, suppose that a second WAS is started in the given LPAR. This WAS specializes in the execution rental car web applications. Now we have two WAS servers, but only one HTTP server. In a base configuration there is only one WAS. Now we need a boss to route the HTTP request to the correct application server. To remind you one more time - more than one WAS under a common administrative control is call a NODE, and a node agent is different type of boss. The Node Agent routes the HTTP request between different application servers. Node agents have nothing to do with performance

However, a Node Agent never works by itself. It needs the help of the Deployment Manager. The deployment manager provides the central point of contact with the web. In a base configuration, the individual application server was responsible for this task. A second job of Deployment Manager is to route the request to a node, which contains an application server, which contains the requested application. If there is only one node this task is simple.

In a large scale WebSphere application deployment, there may be more than one node. A second WebSphere Node may be located in a different LPAR. Remember, that each LPAR contains independent copies of z/OS or other operating systems. A second node may be assigned to another LPAR which is under control of a different z/OS operating system. Extending our previous example, assume a second WebSphere Node is created in a second LPAR. This node contains application servers which contain hotel reservation applications and travel service applications. Now the Deployment Manager, which receives the HTTP request, must now route to nodes located in different LPARs, or different operating system boundaries. There is only one entry point from the web, but there may be multiple physical machines, LPARS, nodes and servant regions. Now J2EE can be extended to include the Workload Manager, Sysplex and Parallel Sysplex designs.

...Thesis: American labor markets are in decline because of global outsourcing which has created jobs overseas, with fewer regulations for the environment and lower costs of operation.   Introduction: Outsourcing can happen to almost anyone. It happened to me. I woke up like any other morning. Went to McDonalds for a cup of coffee and then headed to work. Unlike every other morning though I came to work with my department shut down with no warning and an emergency meeting to tell us that we have been outsourced and are not longer needed. Many American jobs everyday are being outsourced to other countries thus hurting the economy of America and the countries that are getting the jobs. Outsourcing is the practice by which a company hires another company to do some aspect of its work. In this presentation I am going to talk to you about three main points: What are the benefits to companies pursuing an outsourcing agenda, the drawbacks to companies pursuing an outsourcing agenda and the drawbacks to the U.S. economy of the pattern of outsourcing. I. What are the benefits to companies of pursuing an outsourcing agenda? a. According to Farrell (2002) At the top of the list, is the financial impetus.

Assignment 3 Market Model Patterns of Change

...Assignment 3 Market Model Patterns of Change Professor Koros Strayer University The Industry and General Pattern of Change Of Market Model The fast paced industry surrounding health insurance in the United States has experienced rapid growth. There are numerous providers representing a competitive marketplace where no single entity rules over prices. However, the industry is undergoing massive transformation processes and slowly evolving into an oligopoly, where only a few large firms will eventually control market dynamics. Throughout the years there has been more than 500 mergers involving health insurers (Bakhtiari, 2010). Although many small insurance companies operate in the market, the industry Led by WellPoint, 12 health plans cover two-thirds of the enrolment in the U.S. commercial-insurance market (Bloomberg News, 2010) . There are reports that predict over 100 insurers with 200,000 members or less could be pushed out of business, because smaller insurers are unable to invest in the infrastructure and technology to effectively manage care (Bakhtiari, 2010). The good news is that small companies are being merged with larger companies rather than going out of business. The Long and Short Run Behaviors in a “Market Economy” We understand there is no single theory to explain oligopoly behavior, however for this comparison; we will use the Kinked-Demand theory of Oligopoly. The kinked demand model assumes that other firms will ignore the increase, if one......

It increases degree of interdependence among the nations. According to Swedish author Thomas Larsson, “Globalization is the process of world shrinkage, of distances getting shorter, things moving closer. It pertains to the increasing ease with which somebody on one side of the world can interact, to mutual benefit, with somebody on the other side of the world” (Larsson, 2011) There is relationship between Globalization and economic growth. Globalization play important role in international trade. It brought entire world close to each other, which increase competition at international level. It helped to developed new technology, to increased productivity of industries and their workers, also raised workers wages and it lead to economic growth of every countries. (Haase, 2012) The major impact of globalization was reduction in trade barriers and countries open their economy for free trade. First, European and American people experience globalization which increased their per capita income. This was lead to inequality between developed nations and developing nation, because international trade benefited to developed nations and developing nations were not get any benefit from it. But, after 1980s, developing nations like china, India, also involved in the process of globalization and started manufacturing products.......

Hr Outsourcing

...Phida HR OUTSOURCING The Human Resources department or support systems are responsible for personnel sourcing and hiring, applicant tracking, skills development and tracking, benefits administration and compliance with associated government regulations. A human resources department is a critical component of employee well-being in any business, no matter how small. HR responsibilities include payroll, benefits, hiring, firing, and keeping up to date with state and federal tax laws. Any mix-up concerning these issues can cause major legal problems for your business, as well as major employee dissatisfaction. But small businesses often don't have the staff or the budget to properly handle the nitty-gritty details of HR. Because of this, more and more small businesses are beginning to outsource their HR needs. HR outsourcing services generally fall into four categories: PEOs, BPOs, ASPs or e-services. The terms are used loosely, so a big tip is to know exactly what the outsourcing firm you're investigating offers, especially when it comes to employee liability. A Professional Employer Organization (PEO) assumes full responsibility for your company's HR administration. Business Process Outsourcing (BPO) is a broad term referring to outsourcing in all fields, not just HR. Application service providers (ASPs) host software on the Web and rent it to users--some ASPs host HR software. E-services are those HR services that are web-based. Both BPOs and ASPs are often......

India recently opened it’s economy in the last decade from a closed market in 1991.Globalisation has certain impacts on the economy which include economic convergence, economic growth & development, quality of life, distribution of income and wealth. There have been strategies put in place to promote economic growth and development which include. International Convergence International convergence is the tendency of economies becoming more similar in the ways they operate, their consumption patterns, structure of output, economic performance and government systems. The impact of this is an increase in trade dependency with economies formed open and deregulated markets as well as an increase in trade. A positive impact from increased trade is greater efficiency in resource allocation for NIE such as India. Indian exports have grown more than 25% per year to over $100 billion in 2006. (1)It has also led to an increase in level of output as GDP growth for India in 2007 was 9%. (2). As Indian companies began trading on the world market they were forced to become more efficient to allow them to be more competitive.

...BUSINESS PROCESS OUTSOURCING ABOUT BPO BPO stands for Business Process Outsourcing. There is a common misconception that B.P.O. and call centers, mean one and the same. A call centre is a remote location in India wherein calls made by customers abroad are routed to India by means of telecommunication equipments. This call is answered by call centre agents who are trained to speak in an accent which the customer can understand. This accent is commonly referred to as Neutral Accent Coming to the term Business Process Outsourcing, let us understand the term in a simple way by breaking it up. There is a business.

Question 1 - Mattel & Toy Recall (a)

...Question 1: From the case, the characteristics of the toy industry: 1. Seasonal Demand Demand for toys is usually correlated with festive celebrations in a country. One close example is Christmas day which falls in December annually. Coincide with this celebration, significant portion of the toy’s annual sales usually happen towards the end of the year especially in those countries that are dominated by those that celebrate Christmas. The impacts of the seasonal pattern towards the industry are critical as most manufacturers have to consider several factors that lead to sales. The huge demand at certain period of time requires thoughtful planning and smooth execution as minor mistakes can lead to loss of millions of sales value. Just imagine within short period of time toy manufacturers have to produce millions of toys. This requires good management of supplies and synchronization between supplies and production as to minimize costs and ensuring efficiency. Not to forget issues of quality management and lastly the impacts or magnitude of logistic management to the toy manufacturers. 2.

India and Outsourcing

...providers to assume a different identity. They take on a western name, learn to talk with an accent, learn about western cultures to help them deal with western clients. This is forcing Indians to live fake western lives while physically being a part of the Indian reality. What is now emerging is a new dominant culture that is taking over that has changed ways of dressing, speaking, and thinking and has injected a new urban culture with the values of the modernized West. Indians are conforming to the processes of globalization in the name of progress. The cost is losing their identity, culture, heritage and traditions. Some of these cultural changes are reflected in values and religious practices, social interaction and roles and spending patterns. These changes also affect the US companies that have chosen to align or outsource with companies in India. Indians traditionally value peaceful co-existence, spirituality, respect for elders, nature, art, seeking prosperity, strong family ties and hospitality. It is highly collective in terms of society and family and less importance given to individualism. Indian myths, legends and stories stress that good human beings think of the welfare of others before their own. With the impact of call centers, globalization with its emphasis on individualism and secularism is promoting worldviews that differ from the traditional route and has left the Indian youth with a spiritual void and a mix of cultural identities.

Outsourcing

...Outsourcing 1/60 ABSTRACT: The main focus of this project is investigating and exploring the impact of outsourcing on one of the most iconic Danish companies (LEGO), which attracted our attention during the preparation of this project. We decided to focus on a single case study, because we felt that dividing our efforts by investigating more than one company, would not allow us to focus in sufficient detail on the domino effects that outsourcing can have on a singular institution. The main question of this project is “How could LEGO improve the Make-or-buy- decision and the relationship management when it comes to outsourcing”? In order to answer the main question, we must consider two sub-questions stemming from the main issue, namely: “How could LEGO improve the decision-making-process to outsource by taking more influencing factors into consideration?” and “What could LEGO have done differently in its relationship to the outsourcing vendor Flextronics”. We used the Case Study Research method to work on these questions. Doing that, we reviewed theories, which explained the phenomenon of outsourcing on a theoretical basis. After creating a theoretical framework and the database, we analyzed the case (LEGO) for parallels between the theories and their practical experience. Finally, we were able to drawn some conclusions to both the central and subsidiary questions initially posed. In summary, it can be said that LEGO did not take all aspects into...

...The international division of labour refers to the breaking up of the production process in different locations around the world. It can involve a firm setting up offshore branches or divisions in different countries, outsourcing tasks to businesses in other countries, or outsourcing employment to individuals in other countries using technology. Firms have a range of options available to them globally: choosing to produce in a rich country versus a poor country, an urban area versus a non-urban area, outsourcing different functions to different locations, using technology to outsource functions without relocation. Advantages of Global division of labour - Access to a much larger labour force for firms - More competitive labour market drives down labour costs, eg. Wages and working conditions such as sick leave – this leads to falling average costs, increased profits, rising income, employment and economic growth - Increased employment opportunities for employees in developing countries - Increased wages for employees in developing countries - Potential for employees to organise globally to share information and to improve wages and working conditions | Disadvantages of global division of labour - Loss of jobs for employees in the home country - ‘race to the bottom’ of wages due to international competition for employees in import-competing industries -Exploitation of employees in developing countries, leading to poor working conditions, job insecurity,...
