Why Do People Use Or Not Use An Information Technology: An Interpretive Investigation On The Adoption And Use Of An Electronic Medical Records System, Li Long
Theses and Dissertations
In the literature of information technology acceptance, much empirical evidence exists that is inconsistent with Technology Acceptance (TA) Models. The purpose of this study is to find out why the extant TA models fail to predict in reality as they purport to in theory. This research argues that the extant literature has not been able to explain how individuals actually form their perceptions about using an information technology. Since past research attempting to do this has been unsuccessful or empirically refuted, this research uses an interpretive case study to investigate the experiences of professionals’ adoption and use of an information …
An Integrated Knowledge Discovery And Data Mining Process Model, Sumana Sharma
An Integrated Knowledge Discovery And Data Mining Process Model, Sumana Sharma
Theses and Dissertations
Enterprise decision making is continuously transforming in the wake of ever increasing amounts of data. Organizations are collecting massive amounts of data in their quest for knowledge nuggets in form of novel, interesting, understandable patterns that underlie these data. The search for knowledge is a multi-step process comprising of various phases including development of domain (business) understanding, data understanding, data preparation, modeling, evaluation and ultimately, the deployment of the discovered knowledge. These phases are represented in form of Knowledge Discovery and Data Mining (KDDM) Process Models that are meant to provide explicit support towards execution of the complex and iterative …
Shaping Strategic Information Systems Security Initiatives In Organizations, Gurvirender Tejay
Shaping Strategic Information Systems Security Initiatives In Organizations, Gurvirender Tejay
Theses and Dissertations
Strategic information systems security initiatives have seldom been successful. The increasing complexity of the business environment in which organizational security must be operationalized presents challenges. There has also been a problem with understanding the patterns of interactions among stakeholders that lead to instituting such an initiative. The overall aim of this research is to enhance understanding of the issues and concerns in shaping strategic information systems security initiative. To be successful, a proper undertaking of the content, context and process of the formulation and institutionalization of a security initiative is essential. It is also important to align the interconnections between …
An Ontology Centric Architecture For Mediating Interactions In Semantic Web-Based E-Commerce Environments, Manoj Thomas
An Ontology Centric Architecture For Mediating Interactions In Semantic Web-Based E-Commerce Environments, Manoj Thomas
Theses and Dissertations
Information freely generated, widely distributed and openly interpreted is a rich source of creative energy in the digital age that we live in. As we move further into this irrevocable relationship with self-growing and actively proliferating information spaces, we are also finding ourselves overwhelmed, disheartened and powerless in the presence of so much information. We are at a point where, without domain familiarity or expert guidance, sifting through the copious volumes of information to find relevance quickly turns into a mundane task often requiring enormous patience. The realization of accomplishment soon turns into a matter of extensive cognitive load, serendipity …
Developing A Multi-Objective Decision Model For Maximizing Is Security Within An Organization, Jeffrey Lee May
Developing A Multi-Objective Decision Model For Maximizing Is Security Within An Organization, Jeffrey Lee May
Theses and Dissertations
Numerous IS researchers have argued that IS Security can be more effectively managed if the emphasis goes beyond the technical means of protecting information resources. In an effort to adopt a broader perspective that accounts for issues that transcend technical means alone, Dhillon and Torkzadeh (2006) present an array of 9 fundamental and 16 means objectives that are essential for maximizing IS security in an organization. These objectives were derived using a value-focused thinking approach and are organized into a conceptual framework. This conceptual framework provides a rigorous theoretical base for considering IS security in a manner that accounts for …
Power Relationships In Information Systems Security Policy Formulation And Implementation, Michael Stephen Lapke
Power Relationships In Information Systems Security Policy Formulation And Implementation, Michael Stephen Lapke
Theses and Dissertations
This thesis argues that organizational power impacts the development and implementation of Information Systems (IS) Security policy. The motivation for this research stems from the continuing concern of ineffective security in organizations, leading to significant monetary losses. IS researchers have contended that ineffective IS Security policy is a precursor to ineffective IS Security (Loch et al. 1992; Whitman et al. 2001; David 2002; Solms and Solms 2004). Beyond this pragmatic aspect, there is a gap in the literature concerning power relationships and IS Security policy. This research intends to bridge the gap. The dissertation is a two phased study whereby …
Impact Of The Investments In Information And Communication Technologies On Total Factor Productivity In The Context Of The Economies In Transition, Sergey Samoilenko
Impact Of The Investments In Information And Communication Technologies On Total Factor Productivity In The Context Of The Economies In Transition, Sergey Samoilenko
Theses and Dissertations
The goal of this research is to establish a link between investments in information and communication technology (ICT) and economic growth in the context of countries that are currently classified by the international community as transitional economies (TE). More specifically, in this study we focus on the relationship between ICT and one of the determinants of economic growth, total factor productivity (TFP). Neoclassical growth accounting and the theory of complementarity provide the theoretical framework on which we build this research. By combining the data obtained from two sources, the World Bank Database and the IT Yearbook, we were able to …
An Integrative Approach For Examining The Determinants Of Abnormal Returns: The Cases Of Internet Security Breach And Ecommerce Initiative, Francis Kofi Andoh-Baidoo
An Integrative Approach For Examining The Determinants Of Abnormal Returns: The Cases Of Internet Security Breach And Ecommerce Initiative, Francis Kofi Andoh-Baidoo
Theses and Dissertations
Researchers in various business disciplines use the event study methodology to assess the market value of firms through capital market reaction to news in the public media about the firm's activities. Capital market reaction is assessed based on cumulative abnormal return (sum of abnormal returns over the event window). In this study, the event study methodology is used to assess the impact that two important information technology activities, Internet security breach and ecommerce initiative, have on the market value of firms. While prior research on the relationship between these business activities and cumulative abnormal return involved the use of regression …
The Impact Of Relational Model Bases On Organizational Decision Making: Cases In E-Commerce And Ecological Economics, Elizabeth White Baker
The Impact Of Relational Model Bases On Organizational Decision Making: Cases In E-Commerce And Ecological Economics, Elizabeth White Baker
Theses and Dissertations
This dissertation explores reifying the management science concept of organizations as a collection of decisions. Organizational management entails resource allocation activities that can be formulated in terms of elementary relational functions. All elasticity-type formulations, most generic "production" functions, and various projection models that organizations might require (such as sales forecasts) can all be represented by elementary relational functions. Therefore, information systems in organizations can be representative of relationships between decision requirements, as theorized in relational model bases. A relational model-base structure acts as an integrative device by relating an organization's elementary relational functions to each other, with all that is …
Rebuilding Theories Of Technology Acceptance: A Qualitative Case Study Of Physicians' Acceptance Of Technology, Jon T. Blue
Rebuilding Theories Of Technology Acceptance: A Qualitative Case Study Of Physicians' Acceptance Of Technology, Jon T. Blue
Theses and Dissertations
The Technology Acceptance Model has been widely applied and has been quite successful at explaining the behavioral intention to use technology in many organizations. One of the most significant variables in the Technology Acceptance Model is perceived ease of use. The Technology Acceptance Model purports that perceived ease of use contributes to the behavioral intention to use technology. Additionally, the model purports that perceived ease of use is an antecedent of perceived usefulness. In the adoption and use of technology by physicians, previous studies show that the Technology Acceptance Model predictions have been incorrect. Specifically, the aforementioned perceived ease of …
Development Of A Theoretical Model Based Upon Factors Influencing A Firm's Suitability For Organizational Evolution, Ronald T. Sones
Development Of A Theoretical Model Based Upon Factors Influencing A Firm's Suitability For Organizational Evolution, Ronald T. Sones
Theses and Dissertations
Early motion pictures resembled theatre productions on film. Decades would pass before the techniques of special effects and editing evolved to provide the type of movie often shown today. Similarly, early television looked like a radio show where the audience could observe the speakers. Ford's Model T, a "horse-less" carriage. seemed to be designed for a harness. In these examples, successful companies learned how to harness and exploit the power of new technologies--others companies became victims. Companies of the current economy must recognize they face a similar watershed. According to Tom Stewart, the economy effectively transitioned into the Information Age …

Positivism: A Discredited Model Of Science Still In Use In The Study And Practice Of Management, Allen S. Lee
Positivism: A Discredited Model Of Science Still In Use In The Study And Practice Of Management, Allen S. Lee
Information Systems Publications
This paper examines the positivist model of science and the reasons for which philosophers of science have abandoned it. However, despite its discredited status, positivism remains the espoused mode of science in the study and practice of management. The paper will provide examples, identify the harmful consequences, and suggest alternative models.
