Getting from “just-in-case” to “just-in-time”: Insights from a simple model

Many factory managers are hesitant about implementing a just-in-time system due to concern about the dip in productivity that occurs. Here, a simple analytic model is used to study the trade-off between disruption and learning/improvement on a production line. While simple, the model is shown to capture many of the effects of just-in-time mentioned in the literature.Using insights from the model, an attempt is made to identify those factors to which successful implementation of just-in-time is most sensitive.     

Charity box collection schemes: The retailers' view

Most UK charities, both national and local, place boxes in outlets such as shops, bars, cafés, filling stations, banks and building societies. Usually the box is placed by a representative of the charity visiting the potential site and inviting whoever is on duty to accept the box. This research sampled 2,308 UK retailers in order to determine their perceptions of the boxes held on their premises, the number of boxes held, their location and security. From the responses to the survey the authors discuss the distribution of boxes over different retail types and analyse retailers perceptions.     

The way we live: understanding the acquisition of living skills to facilitate the consumer empowerment of young people in the 21st century

This research seeks to understand the perceived sources of acquisition of living skills by young people and to examine the formal and informal channels of acquisition. The study focuses particularly on the concept of living skills. These are the skills of transition, of growing up, and independence. For the purpose of the research the skills investigated are those associated (or formerly associated) with the school subject of Home Economics and were distilled from past curricula and documentation (DES, 1985; SCP, 1971). They cover three types of skill: social/interpersonal, cognitive and manual. Social skills include awareness of others, and a sense of responsibility, which is the basis of child‐care and showing tolerance of and concern and consideration for others. Cognitive skills are those associated with decision‐making and management, they involve thinking, reasoning and the use of knowledge. Manual skills are concerned with the use of the hands, with dexterity and with the achievement of specific goals, for example the ability to use tools and appliances with emphasis on the safe handling of them. They can also be linked to knowledge in terms of, for example aspects of food safety and hygiene. Research to date has failed to tackle the concept of acquisition of the skills of transition from home to independent living. Most research is focused on skills pertaining to a particular occupation role (Newman and Newman, 1988; Blustein et al., 1989; Nurmi et al., 1994) rather than those of living skills. Respondents were asked where they had learnt most about manual, cognitive and social skills. To facilitate analysis the channels were condensed to family (mother, father, other family members), community (friends, voluntary organisations), self (trial and error, television, books and magazines), taught (at school, university and work), with a final category of ‘never learnt’ (categories adapted from Macbeth, 1989). The findings revealed that the perceived acquisition of these living skills was through informal channels. From this research it can be argued that the family, being the main perceived source of acquisition of living skills creates the right time, the right place and facilitates exchange efficiencies. However, in this over‐dependence on an informal framework it is unlikely that discrepancies of skill provision can be alleviated. Additionally, standardisation may be difficult if not impossible to achieve. Compounding this is the tendency of young people to have to resort to self‐learning, which it could be argued is acceptable for some skills but not for those reliant on correct information input (such as food hygiene and nutrition).     

Certified public accountants: Ethical perception skills and attitudes on ethics education

This study investigated the proficiency of CPAs in recognizing and evaluating ethical and unethical situations. In addition, CPAs provided attitudes on ethics education. Respondents were asked to evaluate the ethical acceptability of CPA behavior as presented in six vignettes involving a variety of ethical dilemmas from questions of conflict of interest to questions of personal honor. The results tend to signify that CPAs can, to a degree, distinguish ethical and unethical behaviors. It appears that ethical behaviors and very specific unethical behaviors were more easily identified by practitioners. This may reveal uncertainty and apprehension as to exactly what constitutes unethical behavior since, in many circumstances, this resolution is made on a case-specific basis rather that via a universal rule. In addition, it is interesting to note that CPAs tend to picture themselves as more ethically-oriented than their peers.With respect to ethics education, the CPAs indicated that instruction in ethical concepts and literacy was important and should definitely be embodied in the accounting curriculum as well as at all educational levels. However, the CPAs were remarkably uncertain and ambivalent as to the qualifications of university faculty to provide this instruction and guidance.Suzanne Pinac Ward, CPA, is an Associate Professor of Accounting at the University of Southwestern Louisiana in Lafayette, LA 70504.

Constitutional Rules of Exclusion in Jurisdiction Formation

The rules under which jurisdictions (nations, provinces) can deny immigration or expel residents are generally governed by a constitution, but there do not exist either positive or normative analyses to suggest what types of exclusion rules are best. We stylize this problem by suggesting four constitutional rules of admission: free mobility, admission by majority vote, admission by unanimous consent, admission by a demand threshold for public goods. In a simple model we characterize the equilibria that result from these rules, and provide a positive theory for which constitutional rules will be chosen.     

Considerations in Ethical Decision-Making and Software Piracy

Individuals are faced with the many opportunities to pirate. The decision to pirate or not may be related to an individual's attitudes toward other ethical issues. A person's ethical and moral predispositions and the judgments that they use to make decisions may be consistent across various ethical dilemmas and may indicate their likelihood to pirate software. This paper investigates the relationship between religion and a theoretical ethical decision making process that an individual uses when evaluating ethical or unethical situations. An ethical decision making model was studied for general unethical scenarios and for the unethical behavior of software piracy. The research model was tested via path analysis using structural equation modeling and was found to be appropriate for the sample data. The results suggest that there is a relationship between religion and the stages of an ethical decision making process regarding general ethical situations and software piracy.     

Constructing useful theory: The case of Six Sigma

Organizational practices related to Six Sigma are believed to have resulted in improved organizational outcomes. The academic community, however, continues to lack understanding of the constructs and causal relationships underlying Six Sigma. Hence, discussion of Six Sigma is buffeted by anecdotal experience reported from practice. We evaluate Six Sigma through the lens of literature on theory development to explain why the Six Sigma constructs, assumptions, and causal relationships are inconsistent with theory development principles.
