Interpersonal relations — a theory of interdependence

The major change in the second edition of this book is the addition of a new chapter on probabilistic retrieval. This chapter has been included because I think this is one of the most interesting and active areas of research in information retrieval. There are still many problems to be solved so I hope that this particular chapter will be of some help to those who want to advance the state of knowledge in this area. All the other chapters have been updated by including some of the more recent work on the topics covered. In preparing this new edition I have benefited from discussions with Bruce Croft, The material of this book is aimed at advanced undergraduate information (or computer) science students, postgraduate library science students, and research workers in the field of IR. Some of the chapters, particularly Chapter 6 * , make simple use of a little advanced mathematics. However, the necessary mathematical tools can be easily mastered from numerous mathematical texts that now exist and, in any case, references have been given where the mathematics occur. I had to face the problem of balancing clarity of exposition with density of references. I was tempted to give large numbers of references but was afraid they would have destroyed the continuity of the text. I have tried to steer a middle course and not compete with the Annual Review of Information Science and Technology. Normally one is encouraged to cite only works that have been published in some readily accessible form, such as a book or periodical. Unfortunately, much of the interesting work in IR is contained in technical reports and Ph.D. theses. For example, most the work done on the SMART system at Cornell is available only in reports. Luckily many of these are now available through the National Technical Information Service (U.S.) and University Microfilms (U.K.). I have not avoided using these sources although if the same material is accessible more readily in some other form I have given it preference. I should like to acknowledge my considerable debt to many people and institutions that have helped me. Let me say first that they are responsible for many of the ideas in this book but that only I wish to be held responsible. My greatest debt is to Karen Sparck Jones who taught me to research information retrieval as an experimental science. Nick Jardine and Robin …

Purpose – The purpose of this study is to examine the use of the strategic management tool, Strengths‐Weaknesses‐Opportunities‐Threats or SWOT analysis, and to assess how the methodology has been used as well as changes to the methodology. The findings both for and against SWOT analysis should lead to a balanced view of the technique as well as yield ideas for needed theory building.Design/methodology/approach – Using the ABInform Global® database, academic peer‐reviewed articles were compiled indicating SWOT as one of the article's key index and search words.Findings – The use of SWOT analysis continues to permeate the academic peer‐reviewed literature. Research supports SWOT analysis as a tool for planning purposes. Over the past decade, SWOT research has focused on analyzing organizations for recommended strategic actions. As a methodology for strategic positioning, SWOT analysis has been extended beyond companies to countries and industries and is used in virtually every published business case positi...

The role of readiness for change in ERP implementation: Theoretical bases and empirical validation

In recognizing knowledge as a new resource in gaining organizational competitiveness, knowledge management suggests a method in managing and applying knowledge for improving organizational performance. Much knowledge management research has focused on identifying, storing, and disseminating process related knowledge in an organized manner. Applying knowledge to decision making has a significant impact on organizational performance than solely processing transactions for knowledge management. In this research, we suggest a method of knowledge-based decision-making using system dynamics, with an emphasis to strategic concerns. The proposed method transforms individual mental models into explicit knowledge by translating partial and implicit knowledge into an integrated knowledge model. The scenario-based test of the organized knowledge model enables decision-makers to understand the structure of the target problem and identify its basic cause, which facilitates effective decision-making. This method facilitates the linkage between knowledge management initiatives and achieving strategic goals and objectives of an organization.

Knowledge based decision making on higher level strategic concerns: system dynamics approach

Moderating effects of localization differences on ERP use: A socio-technical systems perspective

In recent years social media has become more and more popular all around the world. This study aims to examine the influence of social media in the e-commerce context and to find how it impacts users' visit intention and purchase intention. Through a questionnaire survey, we test and analyze the research model and its related hypotheses by making use of structural equation modeling. The results indicate that social media interaction ties and social media commitment positively affect normative social influence and informational social influence. The last one in turn influences visit intention and purchase intention in e-commerce. In conclusion, we discuss the research findings and suggest some implications for researchers and practitioners.

The Effects of Social Media on E-Commerce: A Perspective of Social Impact Theory

The introduction of enterprise systems (ES) frequently leads to organizational change, as it involves multiple stakeholders and is associated with fundamental organizational improvements cutting across functional and organizational boundaries. Recognizing that ES implementations are overshadowed by a high failure rate because of resistance to change, this study focuses on the development of readiness for change as a way to ease an IT-driven organizational change, including ES implementations. We find that readiness for change can be enhanced by boosting the relevant individuals' attachment to the organization and their perceived personal competence regardless of the focal ES package and its technological characteristics. We also find that readiness for change positively impacts ES usage intention together with the technological characteristics of the focal ES package. Theoretical and practical implications of the study are discussed along with its limitations.
