The Effects of Computer Support, Social Facilitation, and Arousal of Suspicion on Group Deceptive Communication

Unknown Date (has links)
Today's business organizations emphasize the importance of teamwork and collaboration within work groups more than ever before. Unfortunately, group interaction is not always positive. Very little research has been conducted to investigate the behavior and judgments of group members who are belong to group in which one of the members is deceptive. This study is one of the first attempts to look at this phenomenon, from both the deceiver and receiver sides. Groups of three student subjects engaged in a group negotiation task, with one of the group members randomly assigned the role of deceiver. Groups varied by the availability of computer-supported communication for discussion purposes, their physical proximity with one another, and the number of group members who were warned about the possibility of deception. Hypotheses were developed to predict the amount of deceptive activity and the level of deception detection displayed by group members in each of these circumstances. Results indicated that individuals lied more when using computers to communicate with others and when both of their group partners had been warned. Group members were not proficient at detecting lies in any of the conditions. Implications of these findings and their potential implications for research and practice are discussed. / A Dissertation submitted to the Department of Management Information Systems in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Summer Semester, 2004. / June 17, 2004. / Groups, Computers, CMC, Dispersion, Deception / Includes bibliographical references. / Joey F.

To Catch A Liar: A Cross-Cultural Comparison of Computer-Mediated Deceptive Communication

Unknown Date (has links)
Although much research related to deceptive behavior and its detection has been conducted in the last several years, little of it has focused on deception outside of a North American context. Similarly, most deceptive research has investigated face-to-face verbal communication and neglected computer-mediated communication. As a result, this dissertation is an effort to better understand how computer-mediated communication and espoused cultural values affect deceptive behavior and deception detection. The proposed research model posits relationships between computer-mediated communication media, cue detection, media familiarity, national culture, espoused cultural values, veracity judgment success, and deceptive behavior. An experiment was conducted which looked across two national cultures, Spain and the U.S. Participants served as judges by viewing stimulus tapes via a computer and giving veracity judgments either within or between cultures. Data were collected from a total of 210 subjects and analyzed using structural equation modeling, general linear modeling, and t-tests. Results suggest that Spanish judges were better able to detect deception within their own culture, whereas American judges were better able to detect deception across cultures. Furthermore, the espoused cultural values of masculinity and universalism increased deceptive behavior. Finally, computer-mediated communication was found to increase deceptive behavior relative to face-to-face communication. / A Dissertation submitted to the Department of Management Information Systems in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Summer Semester, 2009. / June 30, 2009. / Deception, CMC, Culture / Includes bibliographical references. / Joey F.

Towards Management Information System in public administration in Uganda

Matovu, James January 2006 (has links)
Thesis submitted in fulfilment ofthe requirements for the award of the Degree of Doctor of Philosophy (Library and Information Science) of the University of Zululand, 2006. / A study based in Uganda, examining and evaluating the theoretical and practical challenges in establishing a management information system (MIS) for public administration. The study focused on the information system at the Ministry of Health (MOH), and Ministry of Finance Planning and Economic Development (MFPED) in the case of Central Government; and that of local administration of five districts, namely, Arua, Bushenyi, Kampala, Masaka, and Mbale. The study involved administration of a survey questionnaire to 530 respondents as well as conducting face to face interviews with 53 respondents. This was on top of the review of the literature that included journal publications, monographs, institutional reports, and conference proceedings. Data collected was analysed using SPSS, Excel, and Epinfo software programs and was later interpreted accordingly. The findings of the study reveal that introduction of new public management, in particular, result oriented management trigger off the desire for the introduction of MIS public administration. Initial efforts towards MIS in public administration proved faulty due to lack of coordination. The effort also resulted in MIS programmes which are limited in scope as they are designed mainly for planning purposes. The steps towards review of the MIS program in 2002 aimed at establishing an integrated MIS program. The leading information needs of public administration were identified as financial management, capacity building, national policy, central government policy, economic conditions and HIV/AIDS. Despite the claim of having an MIS, the information system in place is said to be considerably lacking in the ability to supply adequate, well processed, timely, and easy to use data. The system was found to be lacking in the supply of grey literature, and value added data. Websites suffer from inadequate scope and limited currency. In-house databases by the established information system are non¬existent. The system suffers from the lack of a LAN system, meaning non-availability of online access for most people. It also surfers from undeveloped CD-ROM, and flash disk technology, meaning that information from databases is only accessible in printed form or on diskettes. The MIS programme also suffers from excessive donor dependence, resulting in the development of incompatible systems. Local governments in particular suffer from inadequate computer stock. Public administration, as a whole, suffers from inadequate computer accessories, a problem aggravated by lack of a LAN system to support resource sharing. It also suffers from inadequate computer literacy by both information resource personnel, and public administrators which then results in the under-utilisation of computer resources. To most respondents, the productivity of the MIS program is less that 30 percent of its potential. There is a need to; a) strengthen training in information management, including information gathering, knowledge management, indexing and abstracting service, information analysis and consolidation, and information repackaging; b) establish sectoral information analysis centres with legal deposit rights on government and non¬government publications, to assume management of the national websites and online databases; c) create a Ministry of Information and Communication Technology to elevate the information resource to a ministerial status; d) effect greater investment in group decision support systems as opposed to decision support systems; e) invest in information sharing networks as opposed executive information systems; f) emphasise information reporting and communication as opposed to production of decision models; g) increase government active participation in MIS programs demonstrated through independent budget lines in the national budget and lastly there is a need to integrate the various information systems into a public administration management information network (PAMIN). In conclusion, MIS for public administration is the only way to activate the critical role of information in public administration. Bearing in mind that MIS is computer based, and that the ICT industry is ever changing, the Uganda Government is faced with an uphill task of making MIS a success.

Spacecraft communication

Jaster, Rebecca H. 01 January 2000 (has links)
In many space projects, communication is the principal functional element [1]. Space communications systems are the electronic systems in spacecraft and their counterparts in ground stations (on Earth or on celestial bodies). These systems are required to transmit signals through space [2]. Space communications has played a vital role in the exploration and conquest of space. The need for space communication has evolved from expanding conventional systems for terrestrial communications and from the need to communicate with data-gathering spacecraft [3]. There are two important reasons for spacecraft communication. Space communication makes missions possible and is in the forefront of the development of any spacecraft. Without communication, space exploration would be useless. With the importance of communication in mind, I wanted to learn the elements of spacecraft communication from both the past and present. The three main questions that will be answered in the paper are: • How do we currently communicate with spacecraft? • What are the problems associated with communicating with spacecraft (i.e. delay, interference, and distance)? • How should the system compensate for the Doppler effect that will inevitably occur?

Individual characteristics and distance education success : investigating the role of psychological traits

Delalonde, Charles A. 01 January 2002 (has links)
This paper discusses the role that personality characteristics, specifically an individual's core self-evaluations, play in providing positive distance learning, performance and satisfaction. Drawing from the broader remote work research and the Distance Education Candidate Model (Van Slyke, Kittner, & Belanger, 1998) this paper conducted a field study using a survey instrument to measure the influence of an individual's core self-evaluations on the performance, and satisfaction of individuals involved in a distance-learning course. Data were collected from 142 undergraduate students who completed a web-based version of an introductory management information systems course. Results showed that core self-evaluations did not have an influence on the outcomes of distance-education as a whole. Yet, the research evidenced that computer self-efficacy, self-esteem or locus of control impacted satisfaction perceived performance and actual performance.

Toward an Explanation of the Effect of an Individuals' Culture on Learning Outcomes in a Distance Education Environment

Tupchiy, Anna 01 January 2004 (has links)
There has been much research done on the subject of distance learning; also the same can be applied to the studies of culture and its effect on how people work in groups. However, very little research has been done regarding culture's effects on the outcomes of distance learning. The goal of this research is to show whether cultural traits (individualistic-collectivistic) have an impact ( directly or indirectly) on learning outcomes (satisfaction, perceived learning and objective performance) in a distance education environment. Also, this research will look at the difference between the inherent culture and the sub-culture, which characterizes the community of the class.

The Operations Research Approach for an Effective Management Information System

Mutzman, Joel L. 01 January 1972 (has links) (PDF)
This report serves as an overview to the design of an effective Management Information System (MIS) by incorporating the modeling techniques of an Operations Research (OR) approach. It will be shown that the consideration of OR input requirements mixed with the information requirements for a data base existing at the everyday accounting and operational level creates a responsible management control and decision-making tool. This mix of OR and everyday information approach varies as a function of the managerial activities and the organizational level of effort. In lieu of designing a "total" MIS system, MIS designers should structure a loosely connected federation of MIS sub-systems using the appropriate mix which, for each of the operations, controlling, and planning activities, meets the problem-solvers' requirements. A discussion of the background, definitions, and attributes of MIS and OR will be made in Chapters I and II prior to merging these two entities into a unified concept. Chapter III will develop this concept. A manufacturing organization environment will serve as a point of reference for the formulation of models in the application areas of sales forecasting, production, manpower planning, inventory control, and machine center utilization. I am not proposing a "pipedream" non-realistic approach to a MIS system design that will solve all of management's problems. However, by planting the seeds of OR modeling techniques in the early phase of the design and development, the MIS system will, like a tree, in 3 to 5 years bear the fruit of today's careful planning.
