Health maintenance behaviors of individuals with severe and persistent mental illness in a state prison

The purpose of this grounded theory study is to define health and health-seeking behaviors of incarcerated individuals experiencing severe and persistent mental illness (SPMI) in a state prison. The strategies used to prevent loss of control and maintain health in the prison environment were examined. Nineteen incarcerated individuals with SPMI were interviewed in a state prison. Constant comparative analysis of the data revealed that while establishing a "fit" with the core variable "loss of control" and its identified properties, differences were found in the enactment of health maintenance behaviors related to properties in the prison environment. Several of these behaviors are inconsistent with behaviors expected of individuals in a community day treatment center and reflect a need for bridging programs to facilitate entry into the "free" world. Correctional nurses and mental health providers in this system can advocate for incarcerated individuals with SPMI by developing programs that provide cost-effective intermediate care and collaborating with community health systems for continuity of care. The findings related to alcohol and drug abuse among incarcerated individuals with SPMI challenges mental health providers in both correctional facilities and community-based programs to generate appropriate and effective substance abuse treatment programs for these individuals.     

Marijuana use and depression

The primary goal of this study is to examine the association between marijuana use and adult depressive symptomatology. The key independent variables examined are age of marijuana initiation, frequency of current marijuana use, the use of other licit and illicit drugs, and whether marijuana was used to cope with problems. The relationships among these variables are assessed using data from the Young Men and Drugs Survey (n = 1,941), a nationally representative sample of men from the 1944-1954 birth cohort. Results show that early marijuana initiation appears to be weakly associated with increased depression in adulthood. This effect, however, is mediated by educational attainment, employment status, marital status, and other drug use, notably alcohol and tobacco use. Adult frequency of marijuana use is not significantly associated with increased depression in adulthood. Finally, marijuana users who use the drug to cope with problems are more depressed than those who do not use to cope with problems.     

Policy challenges for child welfare in the new century

Recent changes in public policy reflect increased efforts to scapegoat poor women and children and to polarize the objectives of child protection and family preservation. This article challenges various stakeholders in the child welfare field to move beyond the quick-fix solutions and bureaucratic overregulation precipitated by horror stories of child abuse in the media. The new century presents an opportunity to pursue differential intervention strategies that protect children while empowering poor families and communities.     

Experiments with incentives in telephone surveys

In an effort to counter the problem of noncooperation, survey organizations are offering incentives to respondents with increasing frequency, some at the outset of the survey, as has traditionally been done in mail surveys, and some only after the person has refused, in an attempt to convert the refusal. This article reports on a series of experiments carried out over a period of about 2 years with a monthly telephone survey, the Survey of Consumer Attitudes, in an effort to increase response rates or reduce interviewer effort. We report on experiments with prepaid versus promised incentives; advance letters; and advance letters with prepaid incentives; and we also report on the effects of incentives on response quality, sample composition, response bias, interviewer and respondent expectations, and costs.     

Business planning: The gap between theory and practice

The author maintains that the gap between the theory and the practice of corporate planning is growing. He examines the planning systems currently used and concludes that corporate planning as advocated by the theorists is not being practised in any developed form by large corporations.     

Time lags and the weighted average cost of capital

This paper analyses the effect on the weighted average cost of capital of lags between the times of raising debt and equity finance. It shows the results of such lags when associated with differing levels of gearing and differing costs of debt and equity.     

A set covering approach to bus stop location

This paper considers the problem of locating bus stops in the context of a set covering problem. Zero-one integer programming models are suggested for use in the location of bus stops on new routes and for use in the location of express bus stops on current routes. The models may be used to locate the minimum number of (express) bus stops required to ensure that no passenger need walk more than a specified distance to reach an (express) bus stop. A modified version of the model is presented which enables the router to locate a specified number of (express) bus stops in such a manner that the total distance walked by all boarders is minimized.     

An application of multiple objective linear programming to media selection

A multiple objective linear programming (MOLP) method utilizing interval criterion weights is applied to the problem of media selection. Using this technique, it is possible to analyze a problem more explicitly in terms of the several objectives inherent in many media selection situations. In order to illustrate the interval criterion weights approach, a multiple objective hierarchical media selection model is presented and its computer results discussed. In addition to being able to deal more directly with different decision criteria, a distinguishing feature of the mathematical analysis applied here is that its output enables the media-planner to be presented with a small cluster of candidate media schedules (rather than just one). Then, from this list, the media-planner should be in a position to qualitatively make a final choice as a close approximation to his optimal solution.     

Small Worlds and the New ‘Social Physics’

Abstract In this article I explore the increasing overlaps between ‘sociology’ and ‘physics’ through analysing recent contributions to the social network literature concerned with exploring and explaining the so‐called ‘small world’ phenomenon. I show that this new social network literature, while very provocative, is insufficiently sociological and insufficiently complex. With regard to the former it is demonstrated that a key issue is that of meetingness and hence of travel in order to effect meetingness. Networks have, in other words, to be performed, and they have to come together from time to time, especially to talk. I further show that the small worlds literature is insufficiently complex. Social networks often involve combinations of mobilities and highly structured material immobilities. I conclude the article with an analysis of how a new ‘social physics’ based around the notion of ‘network’ might be established in an era in which time and space seem increasingly warped, bent and twisted into strikingly new topologies.
