Large scale communication networks—Design and analysis

The paper discusses the problem of design and analysis of large scale communication systems. An iterative process, composed of a minimum cost network design algorithm and a network performance algorithm, is presented for the solution of these problems. Computational considerations, using these algorithms, are discussed.     

Physical aggression, forced sex, and stalking victimization by a dating partner: an analysis of the National Violence Against Women Survey

This study used the National Violence Against Women Survey (NVAWS) of women and men to estimate noncohabitating dating violence prevalence by type (physical, forced sex, and stalking), associations between dating violence and other types of interpersonal violence across the lifespan, and association of dating violence with longer-term mental health including substance abuse. Among respondents aged 18 to 65, 8.3% of 6,790 women and 2.4% of 7,122 men experienced physical aggression, forced sex, or stalking victimization by a dating partner. Few (20.6% of women and 9.7% of men) reported more than one type of dating violence. Childhood physical aggression by a parent or guardian was strongly associated with subsequent dating violence risk for men and women. Dating violence (physical aggression specifically) was associated with current depressive symptoms, current therapeutic drug use (antidepressants, tranquilizers, or pain medications), and current recreation drug use for women. Implications for parents, survivors, health care, and service providers are discussed.     

Assessing the effectiveness of strategic planning

This paper describes a method for assessing the effectiveness of strategic planning systems in terms of the results actually observed subsequent to planning activity. The paper explains in particular how, in making the assessment, one might cope with the fact of environmental change subsequent to the setting of planned goals. This ends oriented approach to measuring effectiveness is shown to be complementary to process oriented approaches and is illustrated by an example from the coal industry.     

Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands

Elissen AMJ, Van Raak AJA, Derckx EWCC, Vrijhoef HJM. Improving homeless persons' utilisation of primary care: lessons to be learned from an outreach programme in The Netherlands Faced with rising homelessness, countries around the world are in need of innovative approaches to caring for those without shelter, who, more often than not, suffer from severe health problems. We conducted a case study of an innovative Dutch Primary Care for the Homeless (PCH) programme to gain insight into clients' demographic characteristics, health problems and service use, and to develop an explanation for its success in increasing the latter. Our analyses are based on a combination of quantitative and qualitative data. The results of the study suggest that the success of the PCH programme can be explained by the providers' pragmatism and will to adapt their mode of care provision to the behavioural patterns and needs of their homeless clients.
