The effects of seasonal demand on depot location

Many of the cost functions associated with depot location algorithms assume an overall demand for a fixed period, usually one year. This paper describes an investigation into the effect of high seasonality within such demand figures on the optimal location of storage facilities. The preliminary results indicate that a more flexible approach for certain products could be worthwhile.     

Grief as an Emotion and as a Disease: A Social-Constructionist Perspective

This paper examines grief as an emotion and contrasts it with an alternative conception of grief as a disease. Emotions and (to a lesser extent) diseases are constituted, in part, through their relation to social systems. Recently, there has been a trend toward "treating" grief within the health care system. As this trend continues, grief will inevitably accrue some of the aspects of a disease, and it will lose some of its meaning as an emotion. The theoretical and social implications of this shift in meaning are explored.     

Gynecological services utilization by contraceptive clients: a cost analysis

A cost analysis of gynecological service use by students enrolled in a prepaid health plan at the University of Massachusetts revealed that pregnancy and abortion-related services account for almost half of total costs. The medical records of 495 randomly selected students who presented for diaphragm care during 1980-81 were reviewed and 78% of these women were interviewed. 27% had had at least 1 pregnancy; in 15% of these cases, the pregnancy was diaphragm-related, yielding a Pearl Index of 9.75 pregnancies/100 woman-years of use. Overall, 25% of students (33% of seniors) had an abortion while at college. Study subjects made a total of 1483 visits to the gynecological service and saw an average of 3.3 practitioners. 67% of contraception-related visits were for diaphragm fits, checks, or replacements; 24% involved a change to pills. The average cost per visit for diaphragm fit or method change was $31.20 if the provider was a physician ($22.60 for a nurse practitioner); the cost for diaphragm follow up by a physician was $23.60 ($16.60 for a nurse practitioner). For seniors, the average cost to the health plan over 3.4 years of visits was $83.10 for contraception, $47.43 for pregnancy-related care and abortion counseling, and $100.51 for other gynecological problems (e.g., vaginitis, menstrual disorders) and the annual examination. The $231.04 total cost/senior represents half of the $460 paid in direct premiums. Further analysis is recommended to determine whether increased resource allocation to contraceptive counseling would reduce pregnancy-related costs.     

Shaken baby syndrome: assessment, intervention, & prevention

Child abuse and neglect continue to be parts of a disturbing reality in both the United States and the world. Despite significant advances in the identification and treatment of child abuse, health care professionals are still attempting to grasp the extent of the physiological and psychological effects of child maltreatment and injury. Child abuse, in all of its forms, is preventable, and more must be done to decrease its incidence. Shaken baby syndrome is one of the most deadly and devastating forms of child abuse and is characterized by a traumatic brain injury caused by the violent shaking of an infant. Recognition of high-risk families, combined with education of parents and other caregivers are key to prevention of shaken baby syndrome.     

A COMPUTER LANGUAGE FOR MATHEMATICAL PROGRAM FORMULATION

Using a Conversational Modelling Language (CML), a special computer language has been implemented to allow the specification of mathematical programming models and their parameterization. The language has been designed to be “natural” in the mathematical programming context and to include interfaces with computer routines, such as MPSX, for optimization. Features implemented include equation writing, preparation of computer input, automatic checking and removal of redundancies, and the ability to display solutions given sufficient specification of decision variables. Examples of the use of the language in building interactive decision support systems are given.     

Talking as a primary method of peer defusing for military personnel exposed to combat trauma

1. Humanitarian relief missions and military operations are unquestionably stressful and clearly have potential to affect the mental health of soldiers. 2. After being exposed to traumatic events, soldiers may develop acute stress reactions, a historically known phenomenon better recognized and understood today. 3. Although organized resources exist, they may not be accessible or appropriate. Soldiers are the most precious asset the military forces have and their peers may be the best and only resource available to them. 4. The need to ventilate and the relief that follows after talking about distressing events are evidence that defusing by talking should be encouraged after exposure to a traumatic event.     

Marketing segmentation research—An application to bank services

The research reported here analyses data relating to bank services obtained by a stratified random sampling technique using stepwise linear regression and canonical correlation for the purpose of illustrating the application of segmentation principles to marketing research.     

Solitude: An Exploration of Benefits of Being Alone

Christopher R. Long and James R. Averill, Solitude: An Exploration of Benefits of Being Alone, pp. 21–44.
Historically, philosophers, artists, and spiritual leaders have extolled the benefits of solitude; currently, advice on how to achieve solitude is the subject of many popular books and articles. Seldom, however, has solitude been studied by psychologists, who have focused instead on the negative experiences associated with being alone, particularly loneliness. Solitude, in contrast to loneliness, is often a positive state—one that may be sought rather than avoided. In this article, we examine some of the benefits that have been attributed to solitude—namely, freedom, creativity, intimacy, and spirituality. In subsequent sections, we consider the environmental settings and personality characteristics conducive to solitude, how time spent alone is experienced differently across the life span, and the potential dangers related to the attractiveness of solitude. We conclude with a brief discussion of the theoretical and practical implications of solitude.
