COMPUTER SUPPORTED INSTRUCTION IN STATISTICS: LONG RANGE IMPLICATIONS

This paper reports results of a study designed to measure the long-term impact of computer supported instruction in an introductory business statistics course. Very modest behavioral outcomes were found. Computer supported instruction led to strictly short-term positive attitudinal change toward computers and their value, strictly long-term positive attitudinal change toward quantitative methods and their value, and sustained positive attitudinal change toward computers as a teaching aid.     

SCHOOL ATTENDANCE AND CHILD LABOR—A MODEL OF COLLECTIVE BEHAVIOR

This paper investigates how community attitudes affect school attendance and child labor and how aggregate behavior of the community feeds back on the formation of schooling attitudes. The theory takes aggregate and idiosyncratic poverty into account as an important driver of absence from school and provides an explanation for why equally poor villages or regions can display very different attitudes towards schooling. Distinguishing between three modes of child time allocation, school attendance, work, and leisure, the paper shows how child labor productivity and the time costs of schooling contribute to the existence of a locally stable antischooling norm and how policy can exploit social dynamics and help a community to escape permanently from low attendance at school and child labor.     

THE EFFECTS OF GAME COMPLEXITY ON THE ACQUISITION OF BUSINESS POLICY KNOWLEDGE *

Certain cognitive and affective results obtained by three increasingly complex business games were examined. All simulations taught facts and concepts but the most complex simulation produced the greatest effect. More game complexity also brought about heightened challenge, lesser monotony, and greater decision-making comprehensiveness. Motivational and learning levels, however, were not linearly positive with increasing complexity. The intermediate game was as motivating as the complex one although it was inferior to the simple game as a teaching device. The complex game also experienced higher student mortality.     

An Evaluation of the Role and Performance of a Decision Support System in Business Education*

With the rapid growth in end-user computing, there has been an increasing demand on business schools to train managers in the use of computers for effective decision support. While computer-aided instruction (CAI) has been in vogue for over a decade, there are very few studies that evaluate the impact of computers on decision-making skills in a business education context. The study makes use of a controlled experiment to evaluate the impact of computers on the accuracy and quality of decision making in a business decision support context. It also addresses the relationships between decision performance and various student characteristics such as aptitude, attitude, domain experience, domain expertise, gender, and system experience. The study revealed that computer support positively influenced both dimensions of decision performance.     

The Role of Affect in Attitude Formation toward New Technologies: The Case of Stratospheric Aerosol Injection

This article analyzes determinants of technology acceptance and their interdependence. It highlights the role of affect in attitude formation toward new technologies and examines how it mediates the influence of stable psychological variables on the technology's acceptability. Based on theory and previous empirical evidence, we develop an analytical framework of attitude formation. We test this framework using survey data on attitudes toward stratospheric aerosol injection (SAI), a technology that could be used to counteract global warming. We show that affect is more important than risk and benefit perception in forming judgment about SAI. Negative and positive affect directly alter the perception of risks and benefits of SAI and its acceptability. Furthermore, affect is an important mediator between stable psychological variables—such as trust in governmental institutions, values, and attitudes—and acceptability. A person's affective response is thus guided by her general attitudes and values.     

HOW MANAGEMENT USERS VIEW INFORMATION SYSTEMS

The literature of management information systems suggests that substantial discord exists between management users and systems personnel. This paper describes the current attitudes of managers toward information systems and computers as reflected in seventy-five carefully structured interviews with managers from ten major companies. The author concludes that management user attitudes are quite favorable and do not reflect the predicted discord. In fact, the author believes that one of the major systems implementation problems of the future may be apathy rather than antipathy. The data collection was structured to indicate differences in attitudes on the part of users based on organizational level, functional area of work, type of activity, and type of environment.     

AN EVALUATION OF TWO MODELS OF UNDERGRADUATE STATISTICS

The paper reports on a large scale evaluation of two alternative models of undergraduate statistics courses. The traditional course orientation was compared with a problem-solving orientation in which the emphasis was on real world problem-solving, during the winter and spring quarters of 1973–74. The evaluation battery included behavioral and problem-solving skill measures. The findings indicate that improvements in statistics programs can be made.     

TEACHING EFFECTIVENESS IN THE DECISION SCIENCES: THE USE OF STUDENT EVALUATIONS

This article presents the results of an AIDS-sponsored investigation of teaching effectiveness in the decision sciences. Two national samples were employed in the study: a sample of 247 business school deans and a sample of 3,292 students from 32 different business schools. Included among the findings are that 87 percent of the deans responding indicate they require some sort of faculty teaching effectiveness evaluation, and that great care must be exercised when interpreting student ratings of an individual instructor's teaching effectiveness.     

The Role of Trust in the Affective Evaluation of Novel Risks: The Case of CO2 Storage

There is general recognition that trust and affect are closely connected concepts. Usually, affect is modeled as an antecedent of trust. In the present research, we will argue that, particularly in new situations, trust can also evoke affect toward a risky object. Using structural equation modeling, support was found for the hypothesis that trust influences attitudes through this process. In the present study, we analyzed attitudes toward (carbon dioxide) CO₂ storage. The role of affect appears to be moderated by the level of self-relevance. In the case of high self-relevance (storage nearby), people's attitudes appeared to be merely based on affective reactions and trust. This effect is much weaker under low self-relevance (CO₂ storage in general). In such a case, cognitive factors, more particularly beliefs concerning perceived benefits, were also taken into account in attitude formation.     

CURRICULUM DESIGN AND EVALUATION: INCORPORATING STUDENT PERSPECTIVES ON MAJORS AND CAREERS

In this paper the authors discuss the curriculum evaluation process. The use of student inputs to this process is supported. A demonstration is given of a methodology for analyzing student attitudes towards areas of study in the curriculum, and their perceptions of the relations between those areas of study and the job market.     

AN EMPIRICAL ASSESSMENT OF COMPUTER-ASSISTED DECISION ANALYSIS*

Decision analysis tools often are used in semistructured and ill-structured situations. While some researchers have argued that computerized decision analysis programs may improve decision quality in such situations, research support for this assertion is weak. In this laboratory study, business students used a computerized decision-analysis program with short strategic-management cases to prepare decision reports. Independent raters' perceptions of aided and unaided decision performance were contrasted, attitudes of students toward the program were assessed, individual differences were correlated with attitudes, and the program's impact on students' perceptions of their decision processes and performance was examined. Student attitudes toward the computerized aid were favorable, and individual differences in reactions generally were as predicted. However, the program did not improve the independent ratings of students' decision reports and recommendations. These findings suggest that computerized decision aids should be adopted cautiously. If such aids result in positive user affect and heightened decision confidence without corresponding improvements in decision quality, they may be dysfunctional. Rigorous research methodologies which incorporate independent evaluations of analyses and decisions are recommended for use in future research on computerized decision-analysis programs.     

TOWARD TEACHING EXCELLENCE IN THE DECISION SCIENCES*

Recently the National Commission on Higher Education Issues found serious problems with college-level teaching and recomended educational reforms. This paper describes one attempt at reform—namely, a course at Georgia State University on university teaching for College of Business doctoral students. The 45-hour seminar, based on a university teaching model, covers setting instructional objectives, lecture and discussion methods, teaching methods for higher-level learning, test construction, course evaluation instruments, and instructional and technological innovations. Previous studies have demonstrated repeatedly that teaching improvement seminars can improve teacher and student performance in the classroom. This paper discusses how the seminar could be implemented at other colleges of business administration, extended to faculty development workshops, and ultimately result in a master teacher or instructional professorship.     

Small firms and the information problem

Information is essential for decision-making and strategy by small and medium-sized enterprises. Hans Pleitner explores the content of information used by SMEs based on internal and external information and finds much deficiency. SMEs also have problems with the technicalities of handling information, although there has been a big take-up of personal computers. A lot depends on businessmen's attitudes, and these vary greatly. Dr Pleitner recommends that external institutions should try harder to encourage businessmen in the greater use of information and its technology.     

Conceptualizing leadership perceptions as attitudes: Using attitude theory to further understand the leadership process

Leadership is one of the most examined factors in relation to understanding employee well-being and performance. While there are disparate approaches to studying leadership, they share a common assumption that perceptions of a leader's behavior determine reactions to the leader. The concept of leadership perception is poorly understood in most theoretical approaches. To address this, we propose that there are many benefits from examining leadership perceptions as an attitude towards the leader. In this review, we show how research examining a number of aspects of attitudes (content, structure and function) can advance understanding of leadership perceptions and how these affect work-related outcomes. Such a perspective provides a more multi-faceted understanding of leadership perceptions than previously envisaged and this can provide a more detailed understanding of how such perceptions affect outcomes. In addition, we examine some of the main theoretical and methodological implications of viewing leadership perceptions as attitudes to the wider leadership area. The cross-fertilization of research from the attitudes literature to understanding leadership perceptions provides new insights into leadership processes and potential avenues for further research.     

Size,Skill and Sorting

Abstract. The rise in inequality between the 1970s and the 1990s and the persistent gap in pay between large and small employers are two of the most robust findings in the study of labor markets. Mainstream economists focus on differences in observable and unobservable skills to explain both the overall rising inequality and the size–wage gap. In this paper we model how increasing returns to skill can affect the size–wage gap both with constant sorting and with size‐biased, skill‐biased technological change (e.g. if large firms always had access to computers, but small firms gained access to computers with the rise of affordable personal computers). We analyze the Current Population Surveys from 1979 to 1993 to determine whether large and small employers are converging in terms of mean wages (the employer size–wage effect), wage structures by occupation and education, characteristics of employees, and wage structures by region. We find mixed evidence of convergence and no consistent support for any single version of human capital theory.     

User segmentation of online music services using fuzzy clustering

Given the rapid growth of the Internet, companies are trying to take advantage of its offerings, differentiate themselves from their competitors and be more competitive. These objectives can be achieved by providing personalized and enhanced customer service. As different people can use an online service for different reasons, fuzzy clustering can be useful to identify homogenous groups of potential users and to develop customized strategies for each group, thus enabling companies to increase the personalization of their services and to improve their customer service. This study focuses on the online music industry and presents an application of fuzzy clustering. The results show that there exist homogeneous groups among the potential users of an online music service and that there are differences among the groups with respect to their attitudes, interests, and opinions about the service and computers.

The teaching of business policy—A fresh approach

The artificiality of the circumstances in which much of management education takes place is exemplified in the teaching of business policy where the missing ingredient of responsibility is most crucial. The use of ready made cases compounds this problem by presenting the student with a partly identified problem and the information he must use in tackling it. A different approach in which students prepare their own studies of named companies and discuss their analysis and proposals with senior executives from those companies reduces to a worthwhile degree the artificiality of much business policy teaching. This paper discusses the problems of teaching in this field and describes an approach using the method described above.
