Testing a model of the relationships among organizational performance, IT-business alignment and IT governance.

Testing a model of the relationships among organizational performance, IT-business alignment and IT governance.

Date: December 2003
Creator: Sanchez Ortiz, Aurora
Description: Information Technology (IT) is often viewed as a resource that is capable of enhancing organizational performance. However, it is difficult for organizations to measure the actual contribution of IT investments. Despite an abundance of literature, there is an insufficiency of generally applicable frameworks and instruments to help organizations definitively assess the relationship among organizational performance, IT-business alignment, and IT governance. Previous studies have emphasized IT-business alignment as an important enabler of organizational effectiveness; however, the direct and indirect effects of IT governance have not been incorporated into these studies. The purpose of this study was (1) to propose a new model that defines the relationships among IT governance, IT-business alignment, and organizational performance, (2) to develop and validate measures for the IT governance and IT-business alignment constructs, and (3) to test this IT Governance-Alignment-Performance or "IT GAP" model. This study made some novel contributions to the understanding of the factors affecting organizational performance. The quest for IT-business alignment in the MIS literature has been based on the presumption that IT contributes directly to organizational performance. However, this study found that although IT-business alignment does contribute to organizational performance, IT governance is an important antecedent of both IT-business alignment and organizational ...

A theory for the measurement of Internet information retrieval.

A theory for the measurement of Internet information retrieval.

Date: May 1999
Creator: MacCall, Steven Leonard
Description: The purpose of this study was to develop and evaluate a measurement model for Internet information retrieval strategy performance evaluation whose theoretical basis is a modification of the classical measurement model embodied in the Cranfield studies and their progeny. Though not the first, the Cranfield studies were the most influential of the early evaluation experiments. The general problem with this model was and continues to be the subjectivity of the concept of relevance. In cyberspace, information scientists are using quantitative measurement models for evaluating information retrieval performance that are based on the Cranfield model. This research modified this model by incorporating enduser relevance judgment rather than using objective relevance judgments, and by adopting a fundamental unit of measure developed for the cyberspace of Internet information retrieval rather than using recall and precision-type measures. The proposed measure, the Content-bearing Click (CBC) Ratio, was developed as a quantitative measure reflecting the performance of an Internet IR strategy. Since the hypertext "click" is common to many Internet IR strategies, it was chosen as the fundamental unit of measure rather than the "document." The CBC Ratio is a ratio of hypertext click counts that can be viewed as a false drop measure that determines ...

Toward an Ideal Library: A Synthesis of Wilson's Library and Information Policy and Gilbert's Performance Matrix

Toward an Ideal Library: A Synthesis of Wilson's Library and Information Policy and Gilbert's Performance Matrix

Date: August 2008
Creator: Koremura, Yuka
Description: Inquiry about ideal library was sought by interdisciplinary approach from human competence derived from performance engineering by Gilbert (1978), and the library information policy by Wilson (1977). With Wilson's insights into the field of library and information science (LIS), this work demonstrated the synthesis of Wilson and Gilbert: engineering as common ground. One of the central concerns in LIS, utilization of knowledge, is re-conceptualized as Gilbert's view of performance, which reflected at different vantage points. Four leisurely theorems are introduced for his view of performance engineering, which produce human competence. The performance matrix is the application tool that represents Gilbert's theorems of performance engineering. It is used to clarify vantage points about the library, and constructed a model of the performance engineering system of ideal library. Based upon the model, two applications were made. One is to apply the performance matrix to the existing academic library. Another is to apply the performance matrix for building a special collection. These two applications show that the performance matrix is capable to analyze existing performance system as well as designing and building a performance system.

The transformative library: A narrative inquiry into the outcomes of information use.

The transformative library: A narrative inquiry into the outcomes of information use.

Date: December 2008
Creator: Kenney, Brian
Description: This qualitative study uses narrative analysis to explore the outcomes of information seeking and use among public library users. Twelve women between the ages of 51 and 72, all residents of Fayetteville, Arkansas who self-identified as regular library users, were interviewed to gather their life stories and their experiences using the public library. The participants in this study used information to enable learning and, often, a change in their affective state. The participants used the new information they encountered constructively, to engage with the knowledge and experience they possessed; this use of information always involved reflection, dialogue, or both. The outcomes from these actions are the creation of new knowledge, a change in the participants' meaning schemes, and/or an affective change. In addition, the narratives strongly suggest that information seeking and use by adults in public libraries can sometimes facilitate or, on its own, precipitate a perspective transformation and the adoption of new meanings. Overall, the findings support Mezirow's theory of transformative learning as a model for understanding information use and outcomes among users of the public library. The major implications of this study are two-fold. One, it introduces to information science Mezirow's theory of transformative learning which could provide ...

Tsunami disaster response: A case analysis of the information society in Thailand.

Tsunami disaster response: A case analysis of the information society in Thailand.

Date: December 2009
Creator: Aswalap, Supaluk Joy
Description: The December 2004 Indian Ocean Tsunami wrecked thousands of lives, homes, and livelihoods - losses that could have been avoided with timely and better information. A resource such as information is needed at a fundamental level much like water, food, medicine, or shelter. This dissertation examines the development of the Thai information society, in terms of the share of information workforce and the level of diffusion of information and communication technologies (ICT), as well as, the role of the Thai information society in response to the tsunami disaster. The study combined the historical and political economy analyses in explaining factors influencing the growth of information workforce and the development of ICT in Thailand. Interviews conducted in 2007-08 revealed the Thai information society responded to the 2004 Tsunami - the first global internet-mediated natural disaster - in two areas: on-site assistance in collecting and recording identification information of tsunami disaster victims and on-line dissemination of disaster relief information. The effectiveness of ICT institutions in providing the tsunami disaster relief efforts and increasing the development of the information society were assessed using statistical procedures analyzing the perceptions of the Internet-based survey respondents. The disaster effects on survey respondents were also assessed. The ...

University Students and the Internet: Information Seeking Study

University Students and the Internet: Information Seeking Study

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Shamo, Esmaeel
Description: This study explored university students' information needs and seeking behaviors on the Internet. A Web-based survey was administrated one time. Two hundred responses were received from the target sample within the two weeks period of the study. Data were analyzed with descriptive statistics, factor analysis, and graphical representation. The study explored various issues related to the usability, preferences, and activities of the Internet, such as searching tools, e-mail, search engines, and preferred primary sources of everyday-life information needs. The study explored the perceptions of the students toward the Internet and the traditional library. Kuhlthau's model of the information-seeking process, which includes six stages and affective components, was utilized and modified in the construction of the Web survey. A study by Presno (1998), which includes the four types of Internet anxiety, was utilized in the construction of the Web survey. With regard to the six stages of Kuhlthau model, the majority of the respondents experienced stage 5, which was about information gathering; stage 3 had the next highest number of respondents. Very few respondents experienced stages 1 and 2. There was a systematic pattern in which, the earlier the stages the respondents were in, the more negative adjectives they selected, and ...

User Acceptance of North Central Texas Fusion Center System by Law Enforcement Officers

User Acceptance of North Central Texas Fusion Center System by Law Enforcement Officers

Date: December 2010
Creator: Odabasi, Mehmet
Description: The September 11 terrorist attacks pointed out the lack of information sharing between law enforcement agencies as a potential threat to sound law enforcement in the United States. Therefore, many law enforcement agencies as well as the federal government have been initiating information sharing systems among law enforcement agencies to eradicate the information sharing problem. One of the systems established by Homeland Security is the North Central Texas Fusion Center (NCTFC). This study evaluates the NCTFC by utilizing user acceptance methodology. The unified theory of acceptance and the use of technology is used as a theoretical framework for this study. Within the study, user acceptance literature is examined and various models and theories are discussed. Furthermore, a brief information regarding the intelligence work done by law enforcement agencies are explained. In addition to the NCTFC, several major law enforcement information systems are introduced. The data for this study comes from the users of the NCTFC across the north central Texas region. Surveys and interviews are used to triangulate data. It is found in this study that performance expectancy and effort expectancy are important indicators of system use. Furthermore, outreach and needs assessment are important factors in establishing systems. The results ...

User-Centered Evaluation of the Quality of Blogs

User-Centered Evaluation of the Quality of Blogs

Date: August 2011
Creator: Chuenchom, Sutthinan
Description: Blogs serve multiple purposes, resulting in several types of blogs that vary greatly in terms of quality and content. It is important to evaluate the quality of blogs, which requires appropriate evaluation criteria. Unfortunately, there are minimal studies on framework and the specific criteria and indicators for evaluating the quality of blogs. Moreover, quality is related to user perception, and should therefore be evaluated by the receivers. This dissertation examines the criteria and indicators that blog users consider important for evaluating the quality of blogs, and develops a user-centered framework for evaluating quality by conducting user surveys and post-survey email interviews. The personal characteristics that affect the users’ choices of criteria to evaluate the quality of blogs are examined as well. The study’s findings include 1) the criteria that users consider important when evaluating the quality of blogs are content quality, usability, authority, and blog credibility; 2) the indicators that blog users consider most important for evaluating the quality of blogs are understandability, accuracy, believability, currency, ease of use, and navigation; and 3) gender, education level, age, profession, purpose of use, and specific interests affect the user’s choices of criteria for evaluating the quality of blogs. Future research may involve ...
