Assignment In Client Server Architecture Information Technology Essay

Assignment In Client Server Architecture Information Technology Essay This report focuses on understanding the problems being faced by the Information System (IS) department of Hures as well as other Organisations dealing with human resource and management. Such organizations, private or public, continuously collect and process data (information) using technologies available at an increased rate and store the information in computerized systems. To maintain such information systems becomes difficult and extremely complex, especially as scalability-issues arise. Such problems identified are required to be sorted and find out the solutions. Therefore from the scenario given, the measures were taken into considerations to minimize problems in communication mechanism. The client server architecture was established in the beginning to improve productivity, efficiency and information handling. Nevertheless, the Hures Information System department experienced difficulties as the stored information grew leading to the need of establishing peer to peer architecture, intranets and extranets for security purposes. QUESTION ONE Do you think the problems faced by Hures are unique? Why or why not? The difficulty faced by Hures IS department is not peculiar to them rather the underlying technology. In a distributed environment they were working on, the client server technology had problems when it comes to the extension or scaling servers to accommodate additional loads that were initially not envisaged. Client-server architecture consists of series of clients connected to a common server mounted at some remote or nearby location. Hence when there are load increments in the distributed environment, it usually tends to cause problems that make the architecture difficult to scale accordingly. Moreover, for all users on the network the rate of data transfer might go down, and sometimes a powerful and expensive computer needs to be installed and integrated into the system in an attempt to improve scalability and availability of the server. Nevertheless, for every application under heavy loading, numerous computers may be needed. It is customary to utilise one computer to each server application under medium loading, so as to prevent the extent of damage, for example in the occasion of system failure or violation of privacy and security. Client and servers when connected together to form a network that would facilitate better communication is referred to as a client server architecture. A client is an application or system that accesses a (remote) service on another computer system known as a server by way of a network. Hence servers by their operation receive a message from client and work on them and then return the responses to the client. For instance, file server, web server, mail server and web browser are servers and client respectively (Harkey et aL, 1999). QUESTION TWO Suggest alternative architectures that could be used to overcome the problems faced by Hures current Client/Server technology. Increasingly need of users accessing to network resources (i.e. information) virtually for anything held on a database through a common interface. The network supports between the user and that information. Therefore, distributed system is one of the most ideal for location of resources or database transparency. In general, a server and client systems consist of two major parts which are software and related hardware. On a controlled and shared ground to the clients, servers host resources and make them available. This allows access to server content to be controlled in a much better and secured manner. Basically, client/server architecture is a two tier technology which means that it has two nodes namely a client and a server. In order to improve communication between the client and the server, a third node or interface called a middleware is introduced between the client and the server. This is technically a better design as the middleware which is a form of software between the client and the server processes data for clients such as web browsers e.g. internet explorer, mozilla firefox and safari which are all web client. Middleware store data for user applications enabling a comparatively better design that facilitate server scalability as the processing of requests has been separated by balancing the load on different servers (Harkey, et al, 1999). The role of Middleware in a Client-Server Architecture is illustrated in the figure below: Introducing the middleware results in the design of a three-tier architecture which later can be extended to an n-tier. The n-tier architecture has the disadvantages of impacting or increasing traffic congestion and reducing the design robustness. N-tier architecture becomes more difficult to run and test software than the two-tier architecture due to device congestion resulting in communication difficulties. The increased load in n-tier architecture could lead to overloading of the network. Apart from the mentioned disadvantages n-tier architecture has number of advantages which include: better security control, increased flexibility, user friendly, easy upgradeability and scalability compared to the two tier architecture (Harkey, et al, 1999) The implementation of an n-tier distributed computing architecture will be a solution to overcome problems faced by Hures. N-tier architecture has the potential to provide better, more timely information across the enterprise at a lower cost than the current combination of PC LAN, two-tier client/server, or mainframe applications that have been developed in most organizations. For n-tier architecture to be effective, three key components need to be present: Empowerment of the developer to integrate a distributed computing architecture within existing databases, tools, and components. Certainty of efficient network traffic. Mechanisms to handle load balancing to distribute the work across many servers. The n-tier client/server architecture provides an environment which supports all the benefits of both the one-tier approach and the two-tier approach, and also supports the goals of a flexible architecture. The three tiers refer to the three logical component parts of an application, not to the number of machines used by the application. An n-tier application model splits an application into its three logical component types-presentation logic, business logic, and data access logic, where there may be any number of each of the component types within an application. The application components communicate with each other using an abstract interface, which hides the underlying function performed by the component. This infrastructure provides location, security, and communication services for the application components. The n-tier client/server architecture provides an environment which supports all the benefits of both the one-tier approach and the two-tier approach, and also supports the goals of a flexible architecture. The technology should be able to handle future growth. Hures should carry out n-tier client/server technology to solve their partitioning problems. N-tier client/server architecture is an evolution of the traditional 2-tier and 3-tier models, and is suitable for large business applications where many users share common data and operations on them. Peer to Peer The structure of peer to peer network architectures, they do not have a fixed server responsible for blocking and routing request to and from nodes unlike client server architecture. Peer-to-peer networks are simple and easy to implement. However they fail to render the same performance under heavy loads. Distributed computing, instant messaging and affinity communities are all examples of peer to peer network architecture (Deal, 2005). QUESTION THREE One of the suggestions proposed by Hures IS department is the use of intra net web technology. Examine the pros and cons of such an idea. Intranet can be described as a private version of the internet or network connectivity. It is based on TCPIIP protocols configured for a particular organization system, usually a corporation, accessible only by the organizations members, employees, or others with permission to do so. An intranet website looks and acts just like any other Web sites, but the firewall surrounding an intranet fends off unauthorized access. Like the Internet, intranets are used to share information over a network (Douglas, 2005). Intranet is privately owned computer network that utilizes Internet protocols and network connectivity. It is safe and secure in sharing part of organizational operations such as marketing, administrative information or other matters concerned with the organization and its employees. The techniques, concepts and technologies associated with the internet such as clients and servers running on the Internet protocol suite are employed in building an intranet. HTTP, FTP, e-mail and o ther Internet protocols are also applied. Usually intranets are restricted to employees of the particular firm, while extranets tend to have wider scope so that they can be accessed by customers, suppliers or other authorized agents. On the other hand, intranets like other technologies have their own merits and demerits. Below are some of the advantages and disadvantages of this technology (Stallings and Slyke, 1998). The pros and cons (advantages and disadvantages respectively) for Hures using intranet web Technology were accounted for as follows: Advantages Intranet serves as an effective communication tool within the organization, both vertically and horizontally thereby promoting a common corporate culture where every user is accessing the same information available on a common platform. Intranet enables proper time management, since organizations are capable to make adequate information available to employees on the intranet. This way, employees are able to connect to relevant information within the effective time. Increases the productivity levels of workforce by allowing them to locate and view information faster. It also enables them to use applications relevant to the task at hand. Also, web browsers such as Internet Explorer or Firefox help users to readily access data from any database the organization makes available, subject to security provisions within the companys workstations thereby improving services to users. Intranets have cross-platform capability which enables it to adequately support different types of web browsers irrespective of their backbone be it Java, Mac or UNIX. This ability enhances collaboration since every authorized user is capable of viewing information on the site thereby promoting teamwork. Provide a comparatively cost-effective means for network users to access information or data through a web-browser instead of preparing physical documents like manuals, internal phone list or even ledges and requisition forms. Publishing on the web permits critical corporate knowledge such as company policies, business standards, training manuals etc to be secured and easily accessed throughout the company using hypermedia and other web technologies. It facilitates the business operations and management. Increasingly they are being used as a platform for developing and deploying applications that support business operations and decision making across the whole enterprise. (Goldberg, 1996) QUESTION FOUR Do you think the popularity of intranets and the Internet pose threats to traditional Client/Server systems? Intranet and Internet become popular to some extent because they pose some threats to the traditional Client/server systems. It is true that Internet and intranet are both web technologies. A few years ago, the typical office environment consisted of PCs were connected to a network, with servers providing file and print services. Remote access was awkward, and profitability was achieved by use of laptop computers. Terminals attached to mainframes were prevalent at many companies as well with even fewer remote access and portability options. (Silberschtuz, 2004) Currently the secure intranets are the fastest-growing segment of the Internet comparatively much less expensive to build and manage compared to the private networks. Usually private networks are based on proprietary protocols with mostly client server architecture. An extranet creates a secure tunnel between two companies over the public Internet. It is also used to connect remote employees to corporate network by the use of Virtual Private Networks (VPNs). Also intranets are increasingly being used for tools and applications delivery, which facilitate group work and teleconferencing to an enhanced collaboration within the organizations. In order to increase productivity of organizations, sophisticated corporate directories, sales and CRM tools and project management, are all taking advantage of intranet technology (Robert, et al, 1999). Conclusion The problems faced by Hures like other organization including private and public,which are continuosly collecting and storing data in accelerated rate. The above answers on respective four questions discussed on as follows: If the problems experienced by Hures since 1985 up to now are unique or not, comparing to other organizations, such problems experienced were due to growth of business demands in information systems (IS). For example, Hures was forced to downsize the IS from mainframe to Client/Server network resulted in higher efficiency and profit. Nevertheless the problems arise on the server scaling due to loading capacity, forced the company to incur much cost on implementation of distributed environment with more powerful desktop machines. These problems are not unique because all organizations demand changes in IS while they grow up in business. Secondly, the alternative architectures have been discussed about solving the problems of Heures as well as other organizations in information systems. Therefore, distributed system has been suggested which is the most ideal for location of resources or database transparency in networking environment. Thirdly, the intranet web technology as the special network for special organization suggested by Hures IS department, was discussed on its pros and cons which can be relied on for proper construction of networks in any organization. Finally, we have seen that the popularity of intranets and the Internet pose threats to traditional Client/Server systems since the most fastest growing firms with sophisticated systems have taken advantages of Intranet and Internet technologies to facilitate the efficiency in networking and higher production.

What is happiness

In our current world, as we all regard, money is the tool for getting things we need and want. Everyone uses it and suppressing the money is both tangible and intangible. We work for months and years to have money to buy specific things. ‘A man wants to earn money In order to be happy, and his whole effort and the best of a life are devoted to the earning of that money†. (â€Å"The Myth of Sisyphus â€Å". 1942) Lots of human beings are spending their money to buy some products and services because they believe having these stuffs will make them happy.But what if they wrong? What if there is no real happiness come from money? As far as I am concerned, money is only tool not a purpose while achieving the happiness. Some say ‘ You can't be happy without money because It unlocks everybody'. According to them life offers every kind of opportunity and happiness to the wealthy people. Unfortunately, money can only buy temporary happiness. For reaching more permanent joy and felicity, you need values that are more important than money. First of all, the most essential feature to underline is that there is an illusion and wrong perspective about rich people.Some poor people assert that they would be much more happy If they have lots of money. They watched the celebrities and other wealthy people life on TV or reading from magazines and prejudiced about they are always happy as they look Like on TV. There are lots of famous people Like director Tony Scott, Kurt Cabin, Marilyn Monroe and recently Robin Williams committed suicide due to stress and smashed under the burden of being celebrity. All of these people had huge money when they were alive but suffered from stressful life. As a factual consequence of this,it leads these people to depression.We shouldn't forget that there could be some situations that your money don't work such as: Health. Suppose that, you are rich and earning millions of dollars. In case of Illness, you could easily vault some high-tech medical center and might receive the best treatment,however, there are many diseases which aren't able to cured by medical researchers yet. If you have these kind of incurable disease, it doesn't matter whether you have money or not. You wish to be more healthy instead of being a rich so your money don't buy your health and your happiness Indirectly.In a recent survey inducted by Harvard researchers, it has been detected that money Is not the first priority for people. According to participants who also declared they are happy from their life, money took 3rd or 4th place in their priority ranking. Being healthy, living peaceful life and being with someone you love are ahead of money in that survey. As a factual consequence of this, we can easily say that you can be happy with ordinary income level. Another example is difference between people living in rural and urban areas. In contrast to people living in urban areas and metropolis who has moreIncome, rural living people are more happy and far away from stress. When you each other because of the mutual benefit. In most cases, boy has more money than girl. He think indulging a girl and buying her precious gifts make them happy but money makes the people greedy. Girl starts to want more expensive things so it gives lots of damage their engagement and happiness. Relationships based on money and benefit instead of targeting happiness and respect usually causes irreversible consequences. You will never know what will happen. In case of bankruptcy and poorness, can you sure that you will be as happy as before?To my own view, even if you have millions of dollars, there are still some values and things that you can't afford. Considering the strongly related to the topic of money, we can not ignore that we can still be happy without having a huge money account, mansions or luxury cars. Some poor people dream about being a rich one day and they usually tough ‘ Without money you can't realize your dreams ' but there are more urgent priorities like health,friendship and little happiness that you can't buy with money. Money creates more like temporary, abstract happiness.

Technology And The Dark Web - 936 Words

As technology has propelled forward in our exploration of knowledge relating to computers and their science it is understandable that there are still areas of this field which may yet remain unexplored. One particular field being the Dark Web, which has been defined as an area of the deep web which has, â€Å"been intentionally hidden and is therefore inaccessible through standard [web] browsers.† (Brightplanet.) Although this web has evolved over the course of many years, possibly dating back to the 1990s and the development of onion routing, it has advanced itself into an industry which no one could have ever predicted. Further as well delve deeper into this developmental occurrence known as the Dark Web, I feel that we must ask ourselves how this has evolved into what we know it as today and whether or not it represents our future or past in dealing with the internet activities. As with many events and activities being related to the creation of technology, a few different aspects of it can be tied back to the government. In this case, the Dark Web may be directly related to the, â€Å"creation of ‘Onion Routing’ by the United States Naval Research Laboratory, which was the first step toward the Tor Project.† Nevertheless, this was only the first step to be taken in the greater evolution of the Dark Web, for instance the creation of Freenet which was developed by Ian Clarke allowed more individual to access this otherwise unknown area of the web.

Essay on Sense And Sensibility Themes - 901 Words

quot;Sense and Sensibilityquot; In Jane Austen’s Sense and Sensibility there is a theme that runs along with males in the novel. The first born sons are forced to deal with the promotions and abilities that come along with the laws of primogeniture, yet even with all they get they do not lead an altogether happy life. The men that are quot;first-bornquot; are in fact too swayed by the power and obligation that comes with their estates. In the novel the first sons are viewed in a negative light, yet the second-born sons have less responsibility to be what society wants them to be and are allowed to be his own. Although Edward Ferrars, is a firstborn, his mother disinherits him because of his lack of focus and ability to be all she†¦show more content†¦After John receives the inheritance and the estate, he is from then on viewed in a negative manner. He is a weak man and is constantly influenced by his petty, greedy and mean wife. quot;He was not an ill-disposed young man, unless to be rather coldhear ted and rather selfish to be ill disposed†¦Had he married a more amiable woman, he might have been more respectable than he was: he might even have been made amiable himself. But Mrs. John Dashwood was a strong caricature of himself: more narrow-minded and selfish.quot;(p 3). His choice of wife, a systematic marriage for money and social stature affects his ability to be viewed as a decent character and he is viewed as a whole with his wife, which degrades him even more so. nbsp;nbsp;nbsp;nbsp;nbsp;As far as the Ferrars Brothers are concerned, Edward is the first-born son who quot;seemed to be a second Willoughbyquot; (p 224) but loses his position when he refuses to marry Lucy Steele a rich heiress and wanting to in turn marry Elinor. quot;Mr. Ferrars has suffered from his family†¦he has been entirely cast off by them for persevering in his engagement with a very deserving young woman.quot;(p 243).

Environmental Risk Introduction Plastic bags have been around for ages now and have a multitude of different uses. Since the 1960s, people of all ages have been using these multi-purpose bags for a variety of purposes including shopping, carrying personal items and for dumping garbage (Sugii, 2008). Plastic bags are mostly single-use items which consumers can dispose off once used and took the world by storm once introduced, replacing the popular paper bags. Plastic Bags what makes them useful? Plastic bags are made from a thin layer of plastic textile or film, the most popular being Polyethylene, and sealed together by adhesives or heat-sealed. They are available in a variety of design options to offer all kinds of convenience to the consumer. Some have hard or soft handles in order to offer carrying convenience while others boast easy-to-open and seal options to keep its contents airtight. Examples of such bags include the popular Ziploc bags which are often used to refrigerate edible contents while keeping them airtight. Moreover, plastic bags are leak-free and can be used to transport frozen and wet items without worrying about leakage during transportation. The bags can also be developed in different colors and with messages, which do not wear off very quickly, thus making them popular with businesses, which like to offer their own branded shopping bags to customers.

Guidelines for Writing the Three Major Parts Free Essays

Guidelines for Writing the three major parts of the Literature Review (Introduction, Literature, and Discussion) follow. Directions Do not begin typing until you see the level heading – An Overview and Purpose in your template. The Guidelines are organized by LECTURES and INSTRUCTIONS. We will write a custom essay sample on Guidelines for Writing the Three Major Parts or any similar topic only for you Order Now Lectures and related reading material are included to assist in developing each part of the Review. Where there is to be writing, there are specific Instructions as what is to be included under each heading. Instructions appear in a box. Each instruction is numbered. Respond to ALL NUMBERED INSTRUCTIONS. Introduction to the Literature Insert Your Brief Topic before the Colon: An Overview and Purpose Lecture Note: This section is revised with each new submission of a draft. The introductory section should describe the topic (problem area, guiding concept, theme or research question or problem) that is being reviewed. Aim for an â€Å"eye catching opening sentence†. Sometimes this is a dramatic expression of a number to catch the reader’s attention such as the prevalence of a disease, crime rate, school drop out rate, or sales volume. Be sure the topic is focused on the literature that will be reported. Briefly define the key concepts. Introduce these immediately. The topic should be sufficiently focused to permit an in-depth, substantial investigation, relevant to an area of advanced study/global leadership that guides a range of inquiry, results in an extensive search of scholarly literature, and generation of questions for further inquiry. The purpose of a literature review is presented in the introduction. Bourner (1996) reports the following Purposes – of a literature review – (reasons for a review of the literature) before embarking on a research project. These reasons include: †¢ to identify gaps in the literature †¢ to avoid reinventing the wheel (at the very least this will save time and it can stop you from making the same mistakes as others) †¢ to carry on from where others have already reached (reviewing the field allows you to build on the platform of existing knowledge and ideas) †¢ to identify other people working in the same fields (a researcher network is a valuable resource) †¢ to increase your breadth of knowledge of your subject area †¢ to identify seminal works in your area to provide the intellectual context for your own work, enabling you to position your project relative to other work †¢ to identify opposing views †¢ to put your work into perspective †¢ to demonstrate that you can access previous work in an area †¢ to identify information and ideas that may be relevant to your project †¢ to identify methods that could be relevant to your project Bourner, T. (1996 ). The research process: Four steps to success in T. Greenfield (Ed. ), Research methods: Guidance for postgraduates (pp. 7-11). London: Arnold. Retrieved 8-13-02 from Royal Melbourne Institute of Technology RMIT University http://www. ib. rmit. edu. au/tutorials/literature/litrev. html As you attempt to define concepts (variables) and their relationships to other variables, if applicable, identify causal (independent) variables and effects (dependent variables). You may also identify other variables that can be contextual, intervening, or mediating (see Creswell, pp. 94-95 or other texts). After you introduce the topic area properly (instructions follow), you will develop a succinct one-sentence purpose of the review. Three examples of a concluding purpose statement in the overview are: Example 1: The purpose of this review is to critically analyze the theoretical and empirical literature on web-based instruction as an instructional method in distance education, with an emphasis on effectiveness studies that focus on instructional effectiveness, student learning outcomes, retention, student perceptions of this method of course delivery, and to identify areas of future scholarly inquiry. In this example, the causal variable (independent) is â€Å"instructional method of web-based instruction† and the effects (dependent variable) are instructional effectiveness, student learning outcomes, retention, and student perceptions. Example 2: The purpose of this critical analysis of theoretical and empirical literature is to (a) examine historical and current literature to evaluate whether gender workplace bias exists; (b) explore the impact such a bias would have on women in the workplace, specifically women moving up the corporate ladder; and, (c) identify any theoretical or empirical gaps in the literature for the purpose of suggesting future areas of scholarly inquiry. In this example, the causal variable (independent) is â€Å"gender bias against women in the workplace† and the effect (dependent variable) is mobility up the corporate ladder. Example 3 (Review carefully): The purpose of this critical analysis of theoretical and empirical literature is explore the influence of organizational leadership and other factors on organizational performance, in for-profit and not-for profit service organizations, and to identify areas of future scholarly inquiry. In this example, the causal variables (independent) are â€Å"organizational leadership† and â€Å"other factors†, contextual (intervening or mediating) variables are the type of organization (product versus service) and profit/non-profit, and the effect (dependent variable) is organizational performance. Please note in developing your purpose statement, that the purpose statement begins with The purpose of †¦. and concludes with a statement related to identifying future areas of scholarly inquiry. 9 Instructions: Writing An Overview and Purpose (Follow precisely) *Review Blackboard Forum 5. Use your information and faculty comments for strengthening, as a guide to develop your Overview and Purpose (see items #1-9 below). *Draft 1 is due Week 3. Review Forum 6. You will get a great start if you develop this well. 1. Using the template: a. Develop a preliminary title for the Review and include on the title page. The title should include the main concepts and themes (and/or key theories) for this review. Remember this is a critical analysis of the literature NOT a research study!!!! In no area of this paper, should you refer to this Review of Literature as a research study!!!!!! b. For the Introduction to the Literature, insert a brief subtitle preceding the colon for the level heading: ___: Overview and Purpose. 2. Under the Overview and Purpose, introduce the paper with an â€Å"eye catching† opening sentence for the first paragraph. 3. After the â€Å"eye catching† opening sentence, briefly – describe the topic (problem area, guiding concept, theme). Get to the point – don’t let the reader guess what the review is about –a few sentences. 4. Next include brief definitions of each of the major concepts and cite references for these definitions in appropriate APA format. BE BRIEF – this is not the literature but an introduction to it! Anything you present in the introduction is developed in depth in the Review of the Literature. 5. Next, very briefly, attempt to identify how the literature explains these variables and their relationships to other variables. Include as many as possible variables because this will help in constructing a literature map. The map will show relationships between the variables as you describe here. – Begin with the following: The causal variables (independent are) †¦ The effects (dependent/outcome variables are†¦ Contextual (intervening or mediating) variables that further impact the dependent or outcome variables are †¦. 6. Discuss how the topic area was identified and your reasons (point of view) for selecting the topic area to conduct your critical analysis of the literature. Review the Guidelines: How to Start – Select a Topic and Overview and Purpose, including purposes identified by Bourner (1996). Begin with the following: The topic area of ____ was selected because___. 7. Explain what you want to know about the topic. Review Hart, 1999, p. 14 (Questions the Review Can Answer). Begin with the following: Some questions to be answered through this critical analysis of the literature are:†¦Ã¢â‚¬ ¦ 8. Answer the following: Is the topic about the problems in a discipline or field of study, the processes in a discipline or field of study, or the practices in a discipline or field of study? Processes can refer to various epistemologic processes to develop knowledge (also See Hart, 1999, p. 4). Introduce this clearly so the reader knows what you are speaking about. Begin with the following: The problem area of †¦ is about†¦Ã¢â‚¬ ¦ 9. Conclude the Overview and Purpose with a clearly formulated statement of purpose of the literature review. Use the examples in the guidelines, as a guide to develop this. Make this clear (see examples in the previous lecture note).

Organization of the Review, Scope, and Library Research Plan Organization of the Review Lecture Collect appropriate articles, read critically, identify concepts, theories, and themes, and think about the best way to present your topic. Write these concepts, theories, and themes down (see your Blackboard forum 5 submission and instructor response. Develop a Literature Map. This is a Content Map (Concept Map or Mind Map): All students will have a literature map that will guide the organization of the review and literature search. Build (draw) a visual picture of the concepts and their relationships, which results in a literature map. These evolve from your topic, key concepts, ideas, theme, and/or purpose. Don’t introduce new information or concepts. It should first be introduced in the overview. The literature map is presented in-depth here. There are many methods to organize the review, which often change as you learn more about the topic. Concept Mapping – Representing information in diagram form where key words are linked by lines. These lines are then labeled to express the relationship between the terms. The resulting ‘map’ shows links between key ideas and can then be read through to clarify relationships between key terms. . Definition and Purpose of a Literature Map. This map is a visual/graphic representation of concepts, ideas, and themes that serve to guide thinking. In this case, the purpose is to guide the search and organizational presentation of your review. This map serves to: i. Develop ideas for your review ii. Show relationships and interrelationships between the con cepts, theories, and themes – and if so, what type of relationships iii. Assist in organizing old knowledge and integrating it with new knowledge iv. Guide your literature search plan/strategy v. Identify subtitles (subheadings) to organize your literature review so that you can communicate your ideas systematically. vi. A literature/content map is a creative, intuitive, and artistic endeavor to see how things fit – to generate alternatives. It is also analytical and critical, based on what you are finding in the literature.

Within this folder is information on PowerPoint Presentation and Student Examples. Most of the student examples include literature maps for RES 702 (RES600) students. Organizing the review of the literature by themes, theories, or major concepts and related concepts provides a â€Å"frame for the central topic† to organize. In this case, you may proceed inductively or deductively. http://trochim. human. cornell. edu/kb/dedind. htm Exercise in Deductive/Inductive thinking: http://www2. sjsu. edu/depts/itl/graphics/induc/ind-ded. html#3b For example, a deductive approach might start with the broader view or concept(s) then move to the specific topic area. Example FOLLOWS: A literature map (Figure 1) is used to guide the library search for theoretical and empirical literature about distance learning. The map shows a deductive pattern of the major themes, using an â€Å"interaction line style† type of graphic organizer. Beginning with the broadest concept of distance education, web-based instruction interacts with student characteristics, which leads to evaluation of effectiveness of web-based instruction in distance education. . . Other concepts and their relationships to guide the review are . . †¦Ã¢â‚¬ ¦. Other Organizational Methodologies for Reviews: While RES 702 students are asked to develop literature maps that serve to organize the review, with more scholarly experience and depending upon the topic, you could also present the Review using an â€Å"opposing view† or â€Å"methodological appr oach†. This is not expected now. c. The literature map generates an outline for the Review of the Literature Review â€Å"Why do an Outline, and Basic Outlining skills: http://www. und. du/instruct/wstevens/PROPOSALCLASS/PATRAS. html http://www. mnstate. edu/wasson/ed603/ed603lesson5. htm An outline provides a blueprint, skeleton, or a roadmap for the final written review. An outline is an organizational process that is a logical description of the important components of the literature review. It provides a visual and conceptual design for writing. 1. Identify the main points in the order they should be presented. 2. Differentiate each main heading into logical subheadings. 3. Use further subdivisions if necessary. IT IS STRONGLY SUGGESTED THAT YOU INCLUDE A SECTION ON MEASUREMENT OF YOUR MAJOR VARIABLES. REPORT SOME OF THE MAJOR METHODS, TOOLS, OR INSTRUMENTS THAT HAVE BEEN USED IN PRIOR STUDIES TO MEASURE THE KEY CONCEPTS IN YOUR OUTLINE. Notice in the outline that follows, a sub-level heading is measurement of leadership and organizational performance. In the Review of the Literature section, you would then describe the tools whether qualitative or quantitative, and reliability, validity (quantitative tools), and trustworthiness of qualitative tools. Run a Proquest or Google search such as: â€Å"measurement leadership†. This saves you time in the QP and literature in the †dissertation† where you need to know how your variables have been studied and measured. It is best to have MORE detail in these themes. You can always change later. Example of an Outline: (Let us say that the following concepts are present in the literature map which could be Chain of Events, Clustering, or Interaction Outline. This is an example of an outline (quite detailed). It includes the major concepts that can be used for the literature search, and the outline is placed in the 2nd part of this Review (Review of the Literature) to organize how to present the literature.

Just respond to questions 1-7. . After you design the literature map, begin with the statement: A literature map (Figure 1) is used to guide the library search for theoretical and empirical literature in this review about ___. 1. Next, describe the specific type of organizer that you used to design your map (for example, cluster, chain of events, cycle, etc). To do this, you need to review this syllabus on line , and click the different URL links of examples of visual or graphic organizers (review preceding lecture which provides several types). 2. Identify the specific the concepts, theories, and themes that are in your literature map. 3. Next, briefly, describe the relationships between these concepts, theories and themes (such as what leads to what? Which are the causal, outcome and/or intervening variables? Are the concepts organized inductively or deductively? This all refers to the concepts, theories, and themes in your literature map. 4. Next explain that in addition to guiding the literature search, the literature map serves to identify themes, theories, and concepts that will organize the Literature Review. Present these theories, concepts, and themes in outline form, differentiating each main heading into logical subheadings. (Keep it simple). . Due for draft 1, go to the next major section (Review of the Literature) – insert these themes/concepts as level headings/sublevel headings in outline form. They serve to organize the Review of the Literature. Use appropriate APA (see p. 113 of APA) level headings. An example using APA level headings, is shown in the next major section of these guidelines. The concepts and themes for the example, uses the outline of themes previously discussed (leadership and organizational performance). 6. Insert the Figure 1, Literature Map at the end of this discussion of the Organization of the Review (before Scope and Context). . Make sure that you develop your literature map in a software application that can be copied and pasted into your Microsoft word document containing your paper. b. Make sure the map is an appropriate size and fits within the required paper margins. c. The Figure and #, and Title (Literature Map) belong at the bottom, centered: Figure 1 Literature Map Your goal is to have the map well-developed in draft 1 and finalized in (draft 2). It is expected that this map will change as you â€Å"tighten† and â€Å"organize your literature review in the next section† as well as well as in your qualifying paper. Refine this part with each new draft (and particularly as your literature map evolves). Scope and Context Lecture This section lets the reader know what is and is not included in your literature review (scope). The topic is described in such a way that an appropriate context for the review of the literature is established, in a meaningful, logical way. The key terms here are included/excluded. You can restate the theories, concepts and constructs that you will include and obvious theories, concepts and constructs you won’t include (Look at your problem and topic area). Identify what might be included in the search in terms of types of organizations (public/private; for-profit, not for profit; service/product; types of businesses, types of educational institutions); populations such as young versus old; gender; cultural groups; countries; or type of occupation. The major types of scholarly literature to review are: empirical studies, review articles (critical analysis), theoretical articles/books, methodological articles, and case studies. These types of literature may be in the form of a book, hard copy journal articles, and electronic journal articles. The following are different types and forms of literature: Periodical Abstract in a primary source, Abstract in a secondary source, Periodical (hard copy), Periodical (electronic), Non-periodical (Book), Non-periodical (chapter in a book), Proceeding of meetings or symposia, Doctoral Dissertations (including abstracts), Unpublished work, Audio-Visuals, Newspaper, Government documents, and Electronic Media. Instructions for Writing the Scope and Context 1. As you write this, discuss what is and is not included. Regarding the topic or problem area, discuss what is and is not included in terms of concepts/theories, applications to different populations and settings. 1. Identify the forms (not types) of publications that are included. You don’t need to name specific articles, but identify the forms of literature to be included. 2. Identify the discipline(s) you are focusing in (e. g. , education, health, business, criminal justice, accounting, sociology)? Included specialized areas within these disciplines, such as: gender theories in sociology, accounting ethics, special education for specified populations, urban violence, etc. 3. Identify the scope in terms of the years (period of time) that your literature review covers and exclusions. 5. Discuss whether you are limiting your review to U. S. literature, and/or Global literature. For global literature, identify the â€Å"countries†. If seminal books are emphasized, include the titles. Refine this part with each new draft (and particularly as your literature expands). Library Research Plan and Strategy Lecture THIS IS THE PLAN, NOT THE REVIEW OF THE LITERATURE!! The review is presented in the second major section (Review of the Literature) Searching the Literature: A good review of the literature is dependent upon knowledge of the use of indexes and abstracts, the ability to conduct exhaustive bibliographic searches, and ability to organize the collected data meaningfully. Information literacy skills assist with information seeking and retrieval methods and scholarly communication. Recognize scholarly and peer reviewed journals (See Week 1 Lecture) The e-Learning tutorials about Lynn Library can assist research students with the development of literature reviews using electronic databases, abstracts, bibliographic software, Internet searching, Library catalogue searching, subject resources, off-campus searching, and research and writing skills. You need to complete the tutorials. Library Research Plan/Strategy: In reporting your library plan/strategy, identify concepts, themes (key words) or descriptors and search the relevant databases for research on your topic. Be consistent with the Literature map concepts and themes. Focus your search on primary scholarly works including: empirical, theoretical, critical/analytic, or methodological inquiry. Recognize the differences between these types of scholarly inquiry. Review dissertation abstracts. Did you do a Lynn Library catalog search on the topic (at Lynn)? Did you search selected journals? Did you limit the search to peer-review journals? Did you limit the search to certain years? If you are having difficulty in your library search, you may make an appointment with the Reference Librarian who may assist in building effective search strategies. When visiting the Library, you should come prepared with your search words. Requesting Materials: It is suggested that you read the abstracts before requesting the materials from the Librarian, because certain abstracts may provide enough information to help you make a decision on the material’s relevance. Expect that you will obtain more literature than you will need to include in your literature review. Quantity, however, is not as important as selecting appropriate literature, that is of value and relevant. While many published review articles may have more than 100 cited references, due to time constraints in the course, the expectation is a minimum of 20 â€Å"relevant†, scholarly citations in the text of your paper. Do not go overboard. Quality and relevance is what counts. Don’t use references from â€Å"consulting firms† or firms that are â€Å"promoting† their products or services. Look for scholarly publications. Types and Forms of Literature: Minimum Requirements i. The preference is that you review a variety of types and forms of literature so that you many learn to: ii. Search for and evaluate different types and forms information iii. Integrate a variety of types information in the text of your paper iv. Recognize classic (seminal) works as well as current literature Give yourself time to read the material; do not make a library request for everything at once. Readings: Search Strategy worksheet: http://library. humboldt. edu/infoservices/sstrawrksht. htm http://www. noodletools. com/debbie/literacies/information/5locate/adviceengine. html http://www. lynn. du/clientuploads/Library/Graduatestudentsmanual. doc 11 Instructions for Writing the Library Research Plan and Strategy In a Review, a discussion of the plan or strategy you used to develop your literature search is presented. Don’t discuss what you â€Å"will† do, but rather â€Å"what you did†. 1. Identify the descriptors (concepts, themes, theories, phrases/key words) used to search the relevant databases for research on your topic. Include â€Å"themes† or groups of words used in the search plan. Add the terms â€Å"theory† or â€Å"research† to your themes when you are searching. You should uses many â€Å"themes† to limit the search. Example of a theme for a library search: â€Å"leadership organizational performance research†. Try to include several themes. 2. Report databases used in your library search. 3. Indicate which of the following types of primary scholarly works were reviewed: empirical, theoretical, critical/analytic, or methodological inquiry (aim to obtain all of these)? 4. Were secondary citations of references used in your paper? Explain Why? Review APA p. 247 to understand a secondary citation of a source. Remember that these need to be limited. In your dissertation, you need to mostly use primary sources of literature. Remember that if you report literature from secondary sources in your paper use (as cited in __). 5. Explain if you reviewed dissertation abstracts (yes/no). If so, on what topics, which abstracts? You should use these. 6. Explain if you did a Library catalog search on the topic (at Lynn or where? ) Yes/ or no 7. Provide the titles of the key journals reviewed. (Put these titles in Italics). 8. Indicated whether or not you limited the search to peer-reviewed journals? . Indicate if you limited the search to certain years? If so, which years? 10. Refer the reader to the example of a library Search Print-out that you will place in Appendix A. 11. Report any problems encountered in your library search and how these problems were managed. Refine this part with each new draft. Interest, Significance, and Rationale for the Critical Analysis Lecture In this last part of the introduction to the literature review, you explain the importance and significance of the Review that will follow. As you read more, you will find more rationale as to why this review is important. Provide a transition sentence from this Introduction to the Review of the Literature. Then end with a statement that explains how the Review will conclude in the Discussion section. Example of concluding statement: As an emerging method of instructional delivery in higher education, and one that continually evolves with the growth in technology, it is important to understand its impact on learning, retention, instruction, and students. This critical analysis of the literature concludes with a summary and interpretation of theoretical, empirical, and methodological literature, conclusions, and recommendations for future scholarly inquiry into web-based instruction in distance education. 4 Instructions for Writing the Interest, Significance, and Rationale for the Critical Analysis 1. Discuss if the topic is of limited interest, regional, national, or perhaps of global interest? Explain why? You can include personal interest based on experience and potential applications. 2. Describe why it is worth studying (or examining)? 3. Indicate that the presentation of the Review of the Literature follows 4. Develop a concluding statement (see example above, in lecture) to the effect that a synopsis and interpretations, conclusions, and recommendations are presented at the end of the review in the discussion section. Refine this part with each new draft. Review of the Literature About ___ (add your topic) Lecture This is the second major part of this critical analysis. This has a long lecture. Now is the time to write â€Å"your in-depth Literature Review†. You laid the foundations for this section in the Introduction to the Review, to organize your review according to those themes. Present the theoretical literature (theories, model, constructs, concepts) about those themes, and empirical literature (studies) regarding those themes, in a proper manner. Follow the instructions (see presenting theoretical literature, and presenting empirical literature) in this Review of the Literature section. If you present the literature appropriately in this body of the review, then you will have information to present in the Discussion of the Literature. If you don’t, this Review falls apart. Only literature presented in this Review of the Literature can be analyzed in the next section, Discussion of the Literature. You will save a stitch in time, if you follow instructions and learn how to present theories, and how to present studies, including the authors stated limitations and recommendations for future inquiry, in addition to your critique of those studies. †¢ General comments: The theoretical and empirical literature is summarized, analyzed, evaluated, and synthesized in a more in-depth â€Å"coherent† manner within organized headings and sublevel headings. Specifically, information ertaining to theoretical, empirical, methodological, critical review, and case studies about the topic is reported. As reported previously, expect that you will obtain more literature than you will need to include in your literature review. Quantity, however, is not as important as selecting appropriate literature to present, that is of value and relevant. While many published Review articles may have more than 100 cited references, due to time constraints in the course, the expectation is a minimum of 20 â€Å"relevant†, scholarly citations in the text of your paper. This will increase to 50 references in the qualifying paper. It certainly isn’t unusual to have over 100 references in a dissertation. Do not go overboard. Quality and relevance is what counts. Don’t use references from â€Å"consulting firms† or firms that are â€Å"promoting† their products or services. Look for scholarly publications. As you present literature in your â€Å"word† document, it is okay to talk to yourself. Make notes in the document to your self. You can use different font colors or highlights for these messages to yourself. o Perhaps you want to leave a message to yourself to review a particular article that you didn’t yet have the chance to review, or o you want to search another theme. Or you read an article, but didn’t have a chance yet to write about it – jot down notes o Use the word file as a tool where you keep all information in one place. You will find this technique very helpful in developing the qualifying paper, and in developing the your dissertation. The i nstructor does not mind (and in fact encourages you do to this, even in final copies0. Just make the messages â€Å"neat† – and not to distracting) Of utmost importance, is that you present your review appropriately. Practice doing it correctly immediately or you will be WASTING time (having to redo it later). Your review must be organized within the headings/sublevel headings. Insert the outline developed in the Introduction to the Review. Make sure that the outline is consistent with the organization of themes, concepts add theories in your literature map. †¢ It is ok if you reorganize or rename the themes, but make the changes if the Organization of the R (and literature map, in the prior section). You want the Introduction to the Review, Review of the Literature, and the Discussion section all to be â€Å"internally consistent† with one another. †¢ Instructions follow on how to present CRITICALLY present, theoretical and empirical literature. FOLLOW THESE INSTRUCTIONS. Quotations and Paraphrasing and Critical Analysis †¢ This is a literature review, and not your opinion. Almost all of what you say is referenced, except when you are introducing themes and concepts, and critiquing the theoretical or empirical literature (using appropriate criteria – which is explained later †¢ Reminder: Make sure that you adhere to ethical responsibilities of providing accurate information and communicate effectively. Include â€Å"quote marks† for information that is word for word from another literature source follow APA for (Author, year, p. x). For information that is paraphrased, reference the source as (Author, year). †¢ Whether you are referencing a quote or paraphrased information, NOTE THE LOCATION OF THE â€Å"PERIOD†. IT IS NOT BEFORE THE PARENTHESES BUT AFTER. †¢ Do not copy any material that is word for word or paraphrase without citing sources. †¢ Limit your quotations. We do not w ant a â€Å"summary† or â€Å"copy† of the literature. †¢ You cannot present a â€Å"string of quotes†. (Quote after quote after quote). IMPORTANT: If you paraphrase as you write (it must truly be paraphrasing), cite the (author(s), year. A good way to make sure that you paraphrase is to: †¢ Read material Move the material away from your eyesight †¢ Write out what you recall. †¢ Note: Paraphrasing is not changing the order of words. †¢ Review the Required Information Literacy Tutorial which discusses plagiarism. Review the following URLs about Plagiarism, Student Writing, Citing Sources, and Paraphrasing (IMPORTANT to Review) Plagiarism and Student Writing Paraphrasing, citing sources, use of quotations, plagiarism: http://www. ipl. org/div/aplus/linkciting. htm http://depts. washington. edu/psywc/handouts/pdf/plag1. pdf http://www. hamilton. du/academics/resource/wc/usingsources. html †¢ REFERENCE list and BIBLIOGRAPHY list o Add t he complete bibliographic citation of the article you reviewed to your REFERENCE list in appropriate APA format. Don’t wait until the end when the report is due. This is often one of the worst problems, â€Å"trying to find references†. o REFERENCE list – This contains all literature â€Å"referenced in your paper. o BIBLIOGRAPHY list – This contains all literature reviewed, but NOT referenced in your paper. o If you review literature, but don’t reference it â€Å"immediately† in your paper, place it on your BIBLIOGRAPHY. If you eventually reference in your paper, all you need to do is to cut and paste from the BIBLIOGRAPHY list, to the REFERENCE list. o Literature reviewed is placed on either the REFERENCE or the BIBLIOGRAPHY list, NOT BOTH! Organization of the Review of the Literature †¢ There are no sublevel headings given to you in the template. †¢ The concepts and themes in your literature map AND THE OUTLINE serve as the basis to organize this section. BE CONSISTENT. Insert for draft 1. o Use your literature map and evolving outline to organize these sublevel headings (subtitles) of the literature review. Remember that the concepts and themes in your literature map are theoretical in nature. Thus, in developing the Review, present the concepts and themes conceptually first followed by empirical studies that support or do not support the theoretical formulations. (see guidelines that follow for presenting theoretical and empirical literature) o Follow the organization that you described. If you alter the organization, concepts and themes in this part of the review, go back to the introduction and make the corresponding changes (in the introduction – organization, map, and outline). APA: Organize in a logical, meaningful and orderly manner. Use frequent APA level subheadings to connect main ideas and topics covered in a logical sequence (see APA publication manual for examples, pp. 111-113). The main ideas are concepts and sub-concepts in your literature map. The template for this paper uses five levels of headings (depicted on APA p. 113). The rationale for five level headings i s that you may continue with this Review as your qualifying paper and but more importantly, it may become part of the Second Chapter of a Dissertation (REVIEW OF THE LITERATURE). See p. 13 of APA First Idea, Theme, or Topic (Second Level APA heading, centered italics) First Subconcept or Theme Related to First Idea and Topic (Third Level APA, Left Italics) Related Subconcept or theme (Fourth Level APA, indent ? inch, italics, lower case, end with period). Related Subconcept or theme. Second Subconcept or Theme Related to First Idea and Topic (Third Level APA) Second Idea and Topic First Subconcept or Theme Related to Second Idea and Topic (Third Level APA) Second Subconcept or Theme Related to Second Idea and Topic (Third Level APA) An example follows (next page) Example to organize the review: for the topic the influence of organizational leadership on organizational performance (organized with appropriate APA level headings), and which follow the topical outline presented in the organization of the review (see Introduction to the Literature). Note there are 4 major themes (centered, italics) to organize this review. †¢ In the presentation of the literature review, the first two themes (Leadership and Organizational Performance) would contain â€Å"rich† theory. Who developed the theories, when? how are the concepts in the theories defined? What are the propositions in the theories (statements of relationships), and have propositions in the theories been tested in empirical studies. (See presentation of theoretical literature – and internal and external criticism) †¢ The second two themes Factors Influencing Organizational Performance and Leadership and Performance of Organizations would primarily focus on empirical studies that test the propositions in theories. (See presentation of empirical literature Leadership Classical, Progressive, Risk Leadership Theories Traits and Characteristics of Leaders Leadership, Power and Influence Gender and Equity Issues in Leadership Practice Cultural Issues and Leadership Developing Teams Leading Organizational Change Organizational Leadership Development; Strategic Leadership Leadership Measurement Organizational Performance Dimensions of Organizational Performance Organizational climate.

THIS IS AN ABSOLUTE MUST to understand and apply General Comments Literature reported in the Introduction of this critical analysis (should be very little), but ANY LITERATURE DISCUSSED IN THE INTRODUCTION must also be discussed here in the Review of the Literature – in depth, and linked with the appropriate concept (subtitle). †¢ Present clearly to let the reader know if you are presenting a theory about something (theoretical literature) or a study about something (empirical literature, empirical study, research study). When you don’t use the term â€Å"study about†, it is generally assumed that you are speaking of someone’s theory. The critical analysis review distinguishes between an author’s theorizing or suggesting (author’s interpretations) versus author’s research findings (testing theories). †¢ Always introduce the type of literature you are reporting such as: theoretical literature, empirical literature. For empiric al literature, specify the type of study. This information is usually found in the abstract of the article. For empirical literature introduce as: i. Empirical – Quantitative, Qualitative, Mixed ii. Empirical – Methodological iii. Empirical – Experimental, non-experimental; case study, historical, etc. v. Empirical – Descriptive, exploratory, predictive, explanatory, Reporting Theoretical Literature (IMPORTANT) Kerlinger (1973) presented a helpful definition of a theory that has â€Å"withstood† time. A theory is a set of interrelated constructs (concepts, definitions and propositions) that present a systematic view of phenomena by specifying relations among the variables, with the purpose of explaining and predicting phenomena. Immanuel Kant provided this famous quote: â€Å"Experience without theory is blind but theory without experience is mere intellectual play† http://www. oop. uvic. ca/ArwrCoop/stuprepoverheads/1_Orientation/tsld003. h tm Criteria that can be used to evaluate theories including theoretical frameworks, conceptual models or conceptual frameworks may be organized into internal and external criticism. a. Internal Criticism (of theories) 1. Semantics (Meaning – or definition – given to the elements such as concepts, constructs, variables): Semantics evaluates Clarity, Consistency, Correspondence between theoretical and operational definitions, and intersubjectivity (which is whether similar meanings are used by other scholars). . Syntax: (Logical Structure and Relationships Between the Elements) 1. What are the types of statements (propositions)? laws, postulates, theorems, principles, hypotheses, assumptions, empirical generalizations 2. What are the types of relationships: Time ordered, probabilities, conditional, causal, or concurrent? 3. What are the signs of the relationships? : position; inverse (negative) 4. Note: It is the propositions that are tested in theories, reformulated as hypotheses. 3. Method of Theory Development (What is the method used in theory building – 1. Induction (Grounded theory, codification, definitional reduction or prepositional reduction); Deduction; Synthesis; Logical empirical approach) 2. Patterns: Is there a schematic model depicting the relationships between the concepts? If not, can you diagram the pattern of relationships between the key concepts? 3. Level of theory development: What kinds of outcomes are produced from the theory – (knowledge, principles, solutions, problems)? a. Conceptual framework (definitions only), model (shows relationships between the concepts), and/or a theory (well developed propositions, well linked together, with evidence of empirical support? ) b. Is it Descriptive, exploratory, explanatory, predictive, prescriptive b. External Criticism of a Theory 1. Social Significance: 1. Value to society; theory addresses essential issues in the discipline; 2. Lends itself to further research 3. Efficacy of the theory over another in achieving desired outcomes 2. Social Utility: 1. Pragmatic Adequacy: Is it useful? Does it contribute to understanding? Does it generate new knowledge, provide direction to in professional practice, research, education (pertinent to your topic)? 2. Scope: Is it narrow or broad? What is the degree of generality or abstractness and how does this affect is usefulness (pertinent to your topic)? 3. Complexity/Parsimony: 1. Does it explanation and interrelated many variables? 2. Could a simpler theory achieve the same purpose (parsimonious)? 4. Discrimination: 1. Can the theory be applied to more than one discipline, or is it unique to one discipline? . If it is borrowed from another discipline, are boundary lines demarcated? (example –a variety of disciplines use systems theory) 5. Empirical Validity 1. Does empirical evidence support the theory? Cite some studies. (Is there congruence between theoretical claims and empirical evidence? ) 2. Do results indicate confirmation, verification, support corroboration, or disconfirmation, failure to support the theory? 6. Social Congruence: 1. Does the theory fit with reality? 2. Is it accepted by society? a. When you are reporting theoretical literature, select criteria from the internal and external critical approaches to adequately address your description. Present theories systematically: YOU MUST DO THIS FOR ALL THEORETICAL LITERATURE. 1. First provide a good description of what the author stated about the theory, model, framework, construct or concept. –Example: 1. Introduce the title of the book(s) or theoretical article(s) in your own words which describes the theory (not studies). Next: 2. Begin with the internal critical analysis: a. Report the major concepts and constructs and how these are defined by the author (Semantics) b. Present how the author relates the concepts to one another (Syntax). These are propositions. c. Does the author explain how was the theory developed: Induction (Grounded theory, codification, definitional reduction or prepositional reduction); Deduction; Synthesis; Logical empirical approach) d. Explain how patterns of relationships between the concepts are explained: Is there a schematic/visual model depicting the relationships between the concepts? . Secondly, report what the theorist (or other authors) stated about the External critical review: Social Significance (important), Complexity/Parsimony-simple, Discrimination, Empirical Validity (important) and Social Congruence. It is extremely important that you indicate what the author said about empirical validity: Do they report empirical studies to support the theoretical explanations? When presenting classic or recent theories pertinen t to your topic, you may certainly describe the theory, but also describe the work done to test those theories. 2. Finally, you may provide your critique comments to the above – ie what needs to be strengthened in the theory? Determine if you can succinctly identify key strengths and limitations, and perhaps areas that can be improved? Can you see the linkages between the theory, practice, and research? Does this help to understand a fairly common student question: â€Å"How do we use these models and theories in practice? † Provide a balanced appraisal and sufficient detail (particularly with major theories) so that readers have enough information to draw their own conclusions. Reporting Empirical Studies (Critical! ) – Review the Instructions (you should be familiar with the information based on your critique – consult the worksheets for questions) Reporting methodological studies, you may follow the empirical approach. But focus on: the method being proposed – what method is being targeted? Is it a design? A different sampling approach? Is it a method to measure concepts? Introduce the study title (in your own words), the purpose, and present as above. Reporting Case studies may include use of prior data, or secondary analysis of data for a new study. It may also include a single subject or single organization if a case study. You may follow the above empirical approach is presenting– but be quite clear in presenting whether the authors are using someone else’s data or their own or a single subject or organizational design. Reporting Review Articles (Critical Analysis of the Literature, or Meta-analysis). First Describe what the author said: Introduce the title (in your own words). Describe the purpose of the review and its scope, including the library research plan used to obtain the literature. What sources of information were used (literature, observations)? Present the results, conclusions and future areas of inquiry needed (example: future studies) as reported by the author. Secondly, discuss your critique of the article. Note: Meta-Analyses conduct statistical analysis of other studies (analysis of analyses) General Pointers †¢ Important Note: It is so critical for you to get in the habit, very early on in this process, of presenting theoretical and empirical literature appropriately and systematically. If you do, you will find it easy to develop a nice state of the art of the literature, formulate interpretations, identify important gaps, develop conclusions, and generate recommendations for future study (which is presented in the Discussion section of this report). That is your path toward successfully completing this course, moving on toward a successful qualifying paper (whether or not you stay with the topic), and understanding the dissertation. If you don’t present the literature systematically and appropriately, the review falls apart and can’t be completed. So, plan ahead, follow directions, and you will find your path to success!! Generally, related articles and research findings should be presented together (under the appropriate sublevel heading). o Report areas of agreement and disagreement. o Only a little space should be used to report minor studies. As possible, group together minor studies that have similar results, methodologies, strengths and/or weakn esses. †¢ Major empirical studies or seminal writings (theories). It is appropriate to present major studies or seminal writings individually in more detail. †¢ As you write, you will need to integrate and synthesize the results in some logical manner. You don’t need to report everything that you read! When reading and evaluating the research studies for possible inclusion in your review, determine the relevance, worth and significance of studies to your topic. †¢ While you initially identified some topic, theme, or point that you wanted to develop, you may find that a new or different theme is evolving not initially considered. This may be a reformulation of your topic. If you have questions if this arises, contact the instructor. †¢ The review should contain fairly recent work (post 1995, and preferably 2000+). While older information can be relevant, the review should aim to provide current knowledge (a â€Å"state of the art review†). Remember y ou need to have the â€Å"most recent literature† if it is to be â€Å"state of the art†. o You will find that there are classic studies or theoretical papers repetitively cited in the literature. These are the classic (or seminal) examples of literature in the field. While you would certainly want to refer to these in your review, it would be redundant–and probably irrelevant–for you to review them. It is generally permissible to use secondary sources for some Seminal Literature. Remember that if you do not read the original (primary source) article/theory, but rather you are reporting what someone else says, it is found in a secondary source (use appropriate APA referencing format, as cited in). There should be a limited number of secondary sources in your report. †¢ As you write the Review, you will see that you are generating ideas for the Discussion section- next part – (Interpretations, Conclusions and Recommendations). You can â€Å"jump† to the Discussion as you have further understanding the literature. Do it concurrently while writing this part. You will see that you are summarizing, analyzing, critiquing and relating each literature sources logically to a concept or theme related to the area of inquiry. You are finding a meaningful way to organize the review. You are organizing, integrating and synthesizing the literature and preparing to generate your discussion of conclusions and recommendations! †¢ A good review of the lit erature is more than simply a summary of the research. It is both a critical evaluation of the existing research and a synthesis of that work. You will need to synthesize the literature in some logical manner. This is a skill that develops with practice. As you write things down, review it to see if you are integrating, evaluating, and synthesizing. Are you identifying opposing views, contradictory findings, and gaps in the literature (what questions are being suggested)? Are you bringing clarity to the issues? These will be clearly presented in the Discussion of the analysis, so lay the foundation in this part of the review. †¢ You will see that you are summarizing, but also analyzing, critiquing and relating each literature sources logically to a concept or theme related to the area of inquiry. You are finding a meaningful way to organize the review. You are organizing, integrating and synthesizing the literature! 5 â€Å"big† Instructions on Writing the Review of the Literature About†¦ 1.

In the last 20 years, the theory has been revised and adapted to ___ by ____. Several empirical studies by ___, led to refinement in the theory. Brown (2000) developed a schematic model depicting these direct and indirect relationships among concepts, which continues to be examined today (Smith, 2004). This theory is socially significant addressing essential issues about ___ in the discipline of ___, and is useful in explaining, predicting, and discriminating among those with ___ and those without ___. Thus it is a well-developed guide to ___. The theory has a good balance between simplicity and complexity, contributing to its usefulness. Studies by __ verify the propositions of __. The major proposition with conflicting results in empirical studies is ___. The theory has been adapted to ___ situations and __ populations. This is the predominant theory used to examine ____ with well-developed propositions and strong empirical support. Competing theories are ___ (cite reference).
