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.     

Workforce reentry for people with HIV/AIDS: intervention effects and predictors of success

Treatment that prolongs the lives of people with HIV/AIDS and improves their quality of life is relatively recent and little is known about factors that may predict their successful re-entry to the workforce. No data exist concerning the effectiveness of programs to assist people with HIV/AIDS in their efforts to return to work. We used logistic regression and Kaplan-Meier survival curves to predict return to work using data from 126 individuals who participated in an HIV/AIDS return to work program. Results from the 24 month follow-up revealed that program participation, general health, benefits status, and gender, predicted successful re-entry to the workforce. We discuss these findings in the context of the need for more explicitly-defined interventions, as well as the need for additional information on factors that may hinder or facilitate workforce re-entry among people with HIV/AIDS.     

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.     

Returning to work with HIV/AIDS: a qualitative study

In addition to being an outcome, workforce reentry is a process: People with HIV/AIDS attempting to go back to work must make initial decisions to engage in such an attempt, they then must go through a series of steps that may include re-education or retraining, job searches, résumé development, and other activities. Sustaining employment, in turn, entails its own set of activities. People attempting workforce reentry may also experience barriers on their journeys back to work, they may employ certain strengths to reach their goals, and they may use resources to facilitate preparation for work. Few studies have attempted to study this process. This study was designed to provide an initial attempt to study the process of workforce reentry. Abstracted information from the progress notes of 104 people with HIV/AIDS attempting workforce reentry was qualitatively analyzed using a grounded theory approach to identify themes. Three major themes emerged with reliability: Barriers to workforce reentry, staff-identified strengths, and resources used in workforce-reentry efforts. Although none predicted successful workforce reentry, participants in the study experienced substantial barriers in their workforce-reentry efforts, staff identified significant strengths, and participants used appropriate resources in their efforts to go back to work. Implications for workforce-reentry programs for people with HIV/AIDS are discussed.
