The Use of Native Categories in Management Research

This paper derives from the research project 'The Management of Cooperative Strategies', currently being undertaken by the authors. The authors are, respectively, a social anthropologist and an economist, who are trying to allow their different subject backgrounds to interact within the context of the research, and this paper is one result of this interaction. 'Native categories', or at least the idea of them under various other names, are an important notion within social anthropology, and this paper attempts to explore the usefulness, or otherwise, of the same idea within management research.     

Do poor people have a stronger relationship between income and mortality than the rich? Implications of panel data for health-health analysis

Articles developing health-health analysis have used the observation that richer people tend to face reduced mortality risk to estimate the break-even cost per life saved of health regulations. If government requires that the private sector spend more than this break-even cutoff, the risk of dying due to reduced health investment is increased by more than it will be reduced by the direct action of the health regulation. We use panel data to suggest that the relationship between income and the probability of death is greater for poor people than for the rich. As a consequence, break-even cutoffs are roughly twice as large for the richest 20% of the population than they are for the poorest 20%. The nonlinearity in the income-to-mortality linkage also implies that income transfers between income groups which are ignored in traditional cost-benefit analysis will affect the conclusions of health-health analysis significantly.     

Reliability,Validity, and Classification Accuracy of the DSM-5 Diagnostic Criteria for Gambling Disorder and Comparison to DSM-IV

The DSM-5 was published in 2013 and it included two substantive revisions for gambling disorder (GD). These changes are the reduction in the threshold from five to four criteria and elimination of the illegal activities criterion. The purpose of this study was to twofold. First, to assess the reliability, validity and classification accuracy of the DSM-5 diagnostic criteria for GD. Second, to compare the DSM-5–DSM-IV on reliability, validity, and classification accuracy, including an examination of the effect of the elimination of the illegal acts criterion on diagnostic accuracy. To compare DSM-5 and DSM-IV, eight datasets from three different countries (Canada, USA, and Spain; total N = 3247) were used. All datasets were based on similar research methods. Participants were recruited from outpatient gambling treatment services to represent the group with a GD and from the community to represent the group without a GD. All participants were administered a standardized measure of diagnostic criteria. The DSM-5 yielded satisfactory reliability, validity and classification accuracy. In comparing the DSM-5 to the DSM-IV, most comparisons of reliability, validity and classification accuracy showed more similarities than differences. There was evidence of modest improvements in classification accuracy for DSM-5 over DSM-IV, particularly in reduction of false negative errors. This reduction in false negative errors was largely a function of lowering the cut score from five to four and this revision is an improvement over DSM-IV. From a statistical standpoint, eliminating the illegal acts criterion did not make a significant impact on diagnostic accuracy. From a clinical standpoint, illegal acts can still be addressed in the context of the DSM-5 criterion of lying to others.     

Birth Weight And The Linear Statistical Model

Linear modals are used to disentangle the effects of several factors on the birth weight distribution of human infants. Parameters of interest include the overall mean and standard deviation, mean weights of infants of ‘low’ and ‘high’ birth weight; and proportions of ‘low weight’ infants. Conclusions vary strongly with the parameter concerned and in some instances are quite surprising.     

Themes on circulation in the third world

"This article focuses upon circulation, or reciprocal flows of people, with specific reference to Third World societies." Aspects considered include attempts to standardize terminology and to formulate typologies of population movement; the development of explanatory models of circulation and modernization, social networks, family welfare, and capitalism; and "the transfer of methods and concepts to societies and populations different from those from which they initially evolved and in which they were first tested."     

Meeting the Needs of the Adoption Triangle Through Open Adoption: The Birthmother

Open adoption is a relatively new and controversial practice. However, in many cultures this practice is traditional. In this first of a series of articles, the affect of open adoption upon birthparents is discussed. The open process facilitates appropriate grieving, enables decision making and furthers the growth of the birthmother.     

Comparative institutions and management resiliency in Latin American small-scale fisheries

Encroachment by commercial fleets on small-scale fishing territories throughout Latin America over the last half-century is increasing inter-sector conflict. Small-scale fishery production is crucial to communities that rely on fish as a key source of protein in daily consumption and for supplying increased demand. As the continued viability of local management is threatened, we need to properly understand under what conditions informal institutions are resilient. Seven published Latin American case studies test which model management principles correlate with resilience. Shoreline exchange is identified as an effective practice promoting reciprocity and rapid collective action in the face of external threats.
