The impact of culture on best-practice production/operations management

Significant work has been completed in arriving at what have been put forward as `best practices' for a variety of facets of production/operations management (POM). Organizations are becoming global in their operations. In this environment, there is a desire to learn from this 'proven' best practice and to use the generic ideas, concepts and techniques 'world-wide'. However, it is becoming apparent from a range of fragmented evidence that 'best practices' developed and successful in one context are not necessarily directly transferable to a comparable alternative. More detailed examination suggests that national culture has a significant role to play in determining the precise nature of a best practice in POM, and how universal it might be in its application. This paper examines structures within which to view facets of POM in order to identify one that will facilitate exploration of cultural issues. There follows an identification of what might be considered to be an appropriate range of cultural dimensions along which POM best practices may be considered. A review of the evidence from the literature of cultural impacts on aspects of POM is presented. This is used to support the development of a generic framework to examine this interface more comprehensively.     

Prevalence and correlates of problematic gambling among Danish adolescents

This study reports the findings from a national survey on gambling behaviour among Danish primary school children. A questionnaire was administered to 2,223 primary school students ranging in age from 11 to 17 years. The questionnaire contained a gambling screen (SOGS‐RA) and items that measure gambling behaviour, social network and cognitive perceptions. The prevalence of problem gambling was 1.29 per cent, while 4.5 per cent were categorised as at‐risk gamblers. The three most frequently reported reasons for gambling were to win money, to have fun and to socialise with family and friends. It is suggested that gambling may be linked to a masculine universe and that at‐risk gambling behaviour patterns may be part of a normal adolescent life in which gambling serves recreational or leisure purposes. Implications for further research and preventive measures are discussed.     

Objective and Reputational Rankings of Ph.D.-Granting Departments of Sociology, 1965–1982

Abstract

From its inception in 1965 until 1975 when it stopped publishing such studies, The American Sociologist (TAS) published numerous quality rankings of Ph.D.-granting sociology departments and several articles that compared different rankings. During these years TAS published far more rankings of sociology departments than did any other journal This article reviews these studies as well as the rankings of sociology departments found in three major multi-disciplinary rankings (Cartter, 1966; Roose and Andersen, 1970; Jones, Lindzey, and Coggeshall, 1982). It discusses the major methodological approaches used in these studies and reviews the debate among scholars regarding the most appropriate ways to rank departments. An analysis of the various objective and subjective rankings reveals that there is an elite group of seven departments that consistently rank at the top regardless of the ranking method employed.     

Generating Probabilistic Spatially-Explicit Individual and Population Exposure Estimates for Ecological Risk Assessments

Exposure to chemical contaminants in various media must be estimated when performing ecological risk assessments. Exposure estimates are often based on the 95th-percentile upper confidence limit on the mean concentration of all samples, calculated without regard to critical ecological and spatial information about the relative relationship of receptors, their habitats, and contaminants. This practice produces exposure estimates that are potentially unrepresentative of the ecology of the receptor. This article proposes a habitat area and quality-conditioned exposure estimator, E[HQ], that requires consideration of these relationships. It describes a spatially explicit ecological exposure model to facilitate calculation of E[HQ]. The model provides (1) a flexible platform for investigating the effect of changes in habitat area, habitat quality, foraging area, and population size on exposure estimates, and (2) a tool for calculating E[HQ] for use in actual risk assessments. The inner loop of a Visual Basic program randomly walks a receptor over a multicelled landscape--each cell of which contains values for cell area, habitat area, habitat quality, and concentration--accumulating an exposure estimate until the total area foraged is less than or equal to a given foraging area. An outer loop then steps through foraging areas of increasing size. This program is iterated by Monte Carlo software, with the number of iterations representing the population size. Results indicate that (1) any single estimator may over- or underestimate exposure, depending on foraging strategy and spatial relationships of habitat and contamination, and (2) changes in exposure estimates in response to changes in foraging and habitat area are not linear.     

Dispersion-diminishing transformations

Let D(σ) consist of matrices congruent to and dominated by a given matrix σ , and let T(σ) be the corresponding congruent transformations. These classes are characterized and their properties studied when σ is positive definite. Dispersion orderings are considered, including dispersion-diminishing linear transformations, concentration properties of which are shown. Arbitrary linear transformations are decomposed into contractions, isometries and dilations on subspaces relative to Mahalanobis norms. Applications are noted in statistical process control and linear inference     

Early retirement differences between Denmark and The Netherlands: A cross-national comparison of push and pull factors in two small European welfare states

The goal of this study is to give a comprehensive empirical account of push and pull factors, situated at various societal levels, which may influence people's early retirement. Factors in two contrasting European countries have been analysed and compared: Denmark, where the rate of early exit/retirement is relatively low, and The Netherlands, where this rate is relatively high. Our analysis, looking into possible explanations for the difference in rates, includes factors that operate at the macro or institutional level of the labour market and the social security system, at the meso level of firms and companies, and at the micro level of individual workers. In addition, we not only look into the effects of structural, objective factors, which impacts are usually analysed from an incentive perspective, but also into the effects of cultural factors, i.e. of preferences, attitudes and values. Cultural factors related to early exit have not been the object of much international comparison thus far, although their possible significance is readily acknowledged. The differences in retirement behaviour in Denmark and The Netherlands are explained by the fact that Danish workers, at all three levels, are less experiencing structural and cultural factors pushing them out of the labour market, as well as experiencing factors pulling them into retirement, compared to workers in The Netherlands.
