A Bayesian growth and yield model for slash pine plantations

We formulate a traditional growth and yield model as a Bayes model. We attempt to introduce as few new assumptions as possible. Zellner's Bayesian method of moments procedure is used, because the published model did not include any distributional assumptions. We generate predictive posterior samples for a number of stand variables using the Gibbs sampler. The means of the samples compare favorably with the predictions from the published model. In addition, our model delivers distributions of outcomes, from which it is easy to establish measures of uncertainty, such as highest posterior density regions.     

Management Information Systems and Corporate Planning

If we accept the correlation between MIS and computer based systems then the corporate planner has to consider the impact on his own company of a major new function. In so far as computers and the associated highly paid staff are concerned, the planner is certainly threatened with a major cost growth area that develops a momentum of its own. He may need all his energy to contain this growth in highly expensive resources to a scale that matches the company's overall operations. On the other hand an emphasis on management information and redesigned systems may lead to radical redesign and improvement in profitability of a company's operations. These two aspects are different sides of the same coin and in the future the corporate planner will play a dominant part in determining whether a company enjoys the benefits as well as incurs the costs of a sophisticated MIS.     

Is obesity stigmatizing? Body weight, perceived discrimination, and psychological well-being in the United States

We investigate the frequency and psychological correlates of institutional and interpersonal discrimination reported by underweight, normal weight, overweight, obese I, and obese II/III Americans. Analyses use data from the Midlife Development in the United States study, a national survey of more than 3,000 adults ages 25 to 74 in 1995. Compared to normal weight persons, obese II/III persons (body mass index of 35 or higher) are more likely to report institutional and day-to-day interpersonal discrimination. Among obese II/III persons, professional workers are more likely than nonprofessionals to report employment discrimination and interpersonal mistreatment. Obese II/III persons report lower levels of self-acceptance than normal weight persons, yet this relationship is fully mediated by the perception that one has been discriminated against due to body weight or physical appearance. Our findings offer further support for the pervasive stigma of obesity and the negative implications of stigmatized identities for life chances.     

Remembering the lizard: reconstructing sexuality in the rooms of narcotics anonymous

The crack epidemic was devastating to poor American communities in part because of the destruction wrought by the system of exchanging sex for drugs, which was a key feature of the crack-use culture. Sex-for-drugs exchanges were often conducted under unsafe circumstances and were linked to the spread of AIDS and other STDs, as well as unplanned pregnancies. The existence of this alternative system of sexual relationships threatened the economic viability of established commercial sex work and undermined the status and power of women. Narcotics Anonymous (NA) meetings helped men and women recover from crack addiction through a well-described 12-step process. Described as the rooms, these time- and space-specific encounters helped people become sober in the context of neighborhoods that were centers of the drug trade. Because of the key role of sex in the crack culture, transformation of sexual relationships was essential to establishing and maintaining sobriety. The manner in which the rooms of NA influence the sexuality and lifeworld of addicted people is explored using Barker's theory of ecological psychology.     

Major factors influencing HIV/AIDS project evaluation

This article aimed at finding out if participatory processes (group discussions, enactments, and others) do make a valuable contribution in communication-based project implementation/evaluation and the fight against HIV/AIDS. A case study backed by documentary analysis of evaluation reports and occasional insights from interviews stood as the main methods. To identify values, the state of beneficiaries prior to and after project implementation/evaluation was compared. Participatory processes were noted to have created an enabling environment for project beneficiaries to become activists for social change, leading to the limiting of the spread of HIV/AIDS through sexual behavior and a change of attitude--the essence required for successful intervention. Group participatory processes were also noted to have contributed in overriding, to a great extent, limitations arising from sociodemographic differences in the attainment of project objectives and limitations arising from differences in forms of evaluation (internal versus external evaluators).     

Cost containment in complex social security systems: The limitations of targeting

Two aspects of the structure of existing social security systems limit the scope for containing costs by increasing targeting: the insurance principle, and the use of category membership to establish eligibility for benefits. The first aspect is antithetical to targeting because the most needy people are also the most likely to fail to establish an adequate contributions record. Some countries appear committed to maintaining the insurance principle because it is part of the fabric of the relationship between employers, employees and the State. The second aspect can be seen as an effective way of identifying groups whose income is likely to fall short of their needs. However, the primary function of category definition is to establish the legitimacy of claims—to examine why a shortfall of income in relation to needs has arisen, what personal responsibility the claimant bears, and what alternative mechanisms might be available. Several countries have revised category definitions in response to issues about the motivation and "deservingness" of claimants. We designate as "pseudo-targeting" reforms of this type, which are not likely to result in the allocation of a higher share of social expenditure to the worst-off. The scope for increasing targeting in existing systems is very restricted, reflecting the limitations of the concept. Non-categorical social assistance is the archetypal targeted benefit, and it has serious limitations. The obstacles to targeting are integral to the legitimation of social security. If targeting reforms undermine this legitimating structure, they risk undermining the claim on resources exercised by the social security system.     

Domestic Violence: A case of the Disappearing Victim?†

This article examines the current theoretical constructions of the phenomenon of domestic violence, and their therapeutic implications. It attempts to draw out the latent socio-political content of that theorizing, arguing that throughout the various approaches there is a consistent de-emphasizing of the woman's position as victim of the violent act. An alternative analysis is offered, one which recognizes gender inequality as fundamental to any understanding of domestic violence, and the implications for therapeutic work in this area are briefly explored.
