A new regression model for bimodal data and applications in agriculture

We define the odd log-logistic exponential Gaussian regression with two systematic components, which extends the heteroscedastic Gaussian regression and it is suitable for bimodal data quite common in the agriculture area. We estimate the parameters by the method of maximum likelihood. Some simulations indicate that the maximum-likelihood estimators are accurate. The model assumptions are checked through case deletion and quantile residuals. The usefulness of the new regression model is illustrated by means of three real data sets in different areas of agriculture, where the data present bimodality.     

Objectivism and Bias on the Study of the Israeli–Palestinian Conflict

The author responds to reviews of his book, Planting Hatred, Sowing Pain: The Psychology of the Israeli-Palestinian Conflict. Reviewers argue that you cannot understand the psychology of this conflict from an objective perspective, without taking issues such as historical context and social justice in consideration. The author argues that this detachment is necessary in order to find a solution, since we need to move beyond an orientation to the past that amounts to a culpability paradigm, and into an orientation to the future and a resolution paradigm. Only after you achieve peace and build mutual trust, could the parties be ready to do soul searching and take responsibility for their past actions.     

Alcohol Consumption and Self-Control of Gambling Behaviour

This paper reports the results of a preliminary investigation into whether the drinking of alcohol contributes to impaired control of gambling behaviour. The sampling method consisted of a two-phase survey design, collecting data both prospectively within session and retrospectively via a take-home questionnaire. One hundred sixteen people were interviewed while in a gaming venue playing on an electronic gaming machine (egm) of whom 34 men and 11 women also returned take-home surveys. Comparisons of the sample to previous studies suggested that the sample was representative of the population of egm players. Results indicated a consistent theme of alcohol use contributing significantly to impaired control of gambling behaviour, with level of involvement (Corless & Dickerson, 1989) contributing the most significant variance in the independent variables. Limitations of the study are discussed, but the case is argued that this type of process research is essential in better understanding how these two types of popular leisure activities may interact, possibly leading to the previously recorded chronic, excessive alcohol intake and problematic gambling (e.g. McCormick, Russo, Ramirez & Taber, 1984).     

Street Youth Labour Market Experiences and Crime*

Dans le cadre de notre recherche, nous étudions la façon dont les expériences dans le marché du travail des jeunes sans‐abri et l'inter‐prétation qu'ils font du chômage sont liées à leur comportement criminel. À partir d'entretiens réalisés auprès d'un échantillon de 200 jeunes homines vivant dans la rue, les données recueillies indiquent que ces jeunes se sentent exclus du marché du travail du fait des expériences négatives qu'ils ont vécues. Ce phénomène est exacerbé par le chômage à long terme, qui détruit la motivation et conduit les jeunes à rechercher d'autres exutoires matériels. En outre, les jeunes en viennent à considérer le système social comme injuste et se sen‐tent inaptes à l'emploi, ce qui augmente le risque qu'ils participent à des activités criminelles. Les jeunes qui restent lies à la société tradi‐tionnelle et continuent de croire à l'idéologie dominante du mérite réagissent par la dépression ou la culpabilité menant à une fuite passive et favorisant le comportement criminel. En revanche, les jeunes qui refusent l'idéologie font étant d'un affect négatif minimal et met‐tent en valeur la supérioritý matérielle et sociale qu'ils accordent aux activités criminelles par rapport à l'emploi qu'ils ont pu occuper avant et qui leur était offert. Les conclusions de cet article s'appuient sur les théories de la contrainte, du contrôle et de la sous‐culture. The research explores how homeless street youths' labour market experiences and interpretations of unemployment are linked to criminal behavior. Using interviews with a sample of 200 male street youth, the data suggest that these youths become alienated from the labour market because of negative experiences in their jobs. This is exacerbated by long‐term unemployment that destroys motivation and leaves the youths looking for other material opportunities. Further, the youths come to see the social system as unfair and themselves as unemployable, making it more likely they will become involved in criminal activities. Those youths who remain bonded to the conventional society and continue to believe in the dominant meritocratic ideology respond with depression and guilt, which lead to a passive withdrawal and inhibit criminal behavior. In contrast, those youth who dismiss the ideology display minimal negative affect and reveal that criminal activities are superior both materially and socially to previous and available employment. Findings are discussed in terms of strain, control and subcultural theories.     

THE STRENGTH OF WEAK INDICATORS: A Response to Gilles, Brown, Geletta, and Dalecki

This article responds to Gilles, Brown, Geletta, and Dalecki's (1990) claim that the Legitimate Violence Index (LVX) is invalid because of problems with eight of its twelve indicators and because it is confounded with region and population density.     

CURRICULUM CHANGES TO MEET CHALLENGES: PREPARING MFT STUDENTS FOR MANAGED CARE SETTINGS

Fledgling therapists who graduate from family therapy traning programs will have to navigate the world of managed care. In this article, faculty of University of San Diego share changes in its accredited training program that prepare students for practice in an increasingly multidisciplinary world where health maintenence organizations and other versions of managed care predominate. The paper touches on contextual issues, provides a detailed outline of coursework presenting basic knowledge and skills involved in clinical pracice in a managed care environment, and comments on clinical placements and the challenge of helping the next generation of clinicans "fit" into the future of health care delivery while maintaining their unique identity as family therapists.     

Bargaining within the Supply Chain and Its Implications in an Industry

Our main objective is to investigate the influence of the bargaining power within a chain on its industry. As a building block, we first discuss the implications of bargaining within a single chain by considering an asymmetric Nash bargaining over the wholesale price (BW). We show that both Manufacturer Stackelberg (MS) and vertical integration (VI) strategies are special cases of the BW contract. We then develop the Nash equilibrium in an industry with two supply chains that use BW. We identify the profit‐maximizing (coordinating) bargaining power within this industry. We show that when a chain is not monopolistic, VI does not coordinate the chain and that the MS contract, where the manufacturer has all the bargaining power, is coordinating when competition is intense. We find that the main determinant of the equilibrium in mature industries is to respond well to the actions of the competing chain rather than to directly maximize the profit of each chain. That is, the equilibrium does not necessarily maximize the profit of the entire industry. While a coordination of the industry could then increase the profitability of both chains, such a coordination is likely against antitrust law. Moreover, if one chain cannot change its actions, the other chain may unilaterally improve its profitability by deviating from the equilibrium. Our results lead to several predictions supported by empirical findings, such as that in competitive industries chains will work “close to” the MS contract.     

Barriers to Training for Disabled Social Work Students

Disabled people wishing to enter Higher Education are confronted with a number of barriers, yet relatively little research has been carried out to identify the level and nature of such obstacles. The short study reported here was designed to examine policy and practice within a number of social work training institutions in Scotland. Interviews were held with disabled students and ex-students, course tutors and practice teachers. Barriers to training are identified in five main areas: first, the disabling physical environment; secondly, problems of typification (whereby global assumptions of impairment are made about individuals); thirdly, failure of equal opportunities policies; fourthly, the practice of treating all students in the same way, resulting in discrimination against a few; and, finally, self-censorship on the part of students. It is argued that the reluctance of some students to 'declare' an impairment is a rational response to the disabling policies pursued, albeit inadvertently, by institutions. The implications of these findings for policy and practice are discussed.     

The Drug‐Laden Balloon: U.S. Military Assistance and Coca Production in the Central Andes*

Objective. This article explores the empirical effects of U.S. drug policy on coca cultivation in the Central Andes. We assess the impact of U.S. military assistance on the production of coca in the Central Andes, while controlling for other explanatory variables that influence coca cultivation. Method. Using data from 1980–2001 for Colombia, Bolivia, and Peru, we perform a pooled cross‐sectional time‐series analysis. Results. The effects of U.S. military assistance on coca cultivation are not uniform across the Central Andes. Coca production decreased in Bolivia and Peru and increased in Colombia. Total coca production in the Central Andes, however, remained unchanged. Conclusion. This study is consistent with existing literature that points out the obstacles governments face as they attempt to suppress illicit goods. Specifically, our empirical findings support the idea of the “balloon effect,” whereby government efforts to “squeeze” illicit trade in one area result in the expansion of that trade elsewhere.
