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.  相似文献

To help evaluate the risk of process reengineering failure and enhance the prospect of its success, three potential sources of influence on BPR initiatives and success are examined in this study. These include the innovative capacity of the organization, IS maturity and strategy-IS interface. It was found that while factors related to IT maturity and influence such as experience in mainframe and client/server computing may facilitate the decision to reengineer, they are not critical in the later stages of the initiative. On the other hand, factors having significant relationships beyond the initial decision include variables pertaining to innovative capacity of the organization and strategy-IS interface. These findings suggest that technical IT competence as a critical enabler is necessary but not sufficient for reengineering success. Based on study findings regarding the innovative capacity of the organization, guidelines for reengineering risk assessment are proposed. In addition, implications of the findings, limitations of the study and opportunities for further research are also discussed.  相似文献

With advances in life-extending medications and later- life infections, the number of older adults with HIV is increasing. Unfortunately, the synergistic effects of aging with HIV may place many people at risk of developing cognitive impairments which can disrupt everyday functioning. Fortunately, cognitive reserve may be maintained, or in some cases improved, by taking action to prevent or mitigate such loss. Preventative and treatment strategies that support biopsychosocial aspects of cognition include reducing alcohol and substance use; improving nutrition; diminishing the effects of comorbidities; increasing social contact; reducing depression and stress levels; engaging in cognitively stimulating activities; applying cognitive remediation therapies; and incorporating psychopharmacological interventions. Such strategies can improve the physiological integrity and health of the brain, thus supporting neuroplasticity and increasing cognitive reserve. Social workers are in a favorable position to recognize cognitive decline in clients and recommend or administer solutions to address such problems. A model for social workers advocating for older clients with HIV who have cognitive problems is provided.  相似文献

One strand in the current debate on AMT investment emphasises technical aspects of investment appraisal. Another calls for a broader focus on wider decision-making processes and strategic considerations. This paper seeks to merge both sets of concerns. It uses two empirical studies of AMT decisions in a number of companies. The first demonstrates specific linkages between manufacturing strategies and financial justifications. The second explores ways in which connections between finance and strategy are constructed and how they are understood and evaluated by decision-makers. We conclude that AMT proposals succeed by linking accounting information to strategic considerations throughout the investment decision process.  相似文献

As the number of older adults with HIV/AIDS increases, new challenges are emerging that threaten their ability to age with this disease. Threats of particular concern are depression and suicidal ideation. Studies show that those aging with HIV/AIDS have a number of stressors that tax their coping mechanisms, increasing vulnerability to depression and suicidal ideation. These stressors can be categorized into three areas. First, there are psychosocial stressors that can contribute to depression. Second, there are health and biochemical stressors that can contribute to depression, as well as compromise cognitive abilities needed to adapt to such stressors. Third, cognitive stressors may create predispositions to depression. In particular, certain cognitive abilities needed to cope with depression and suicidal ideation may be compromised by aging with HIV/AIDS. A model of these stressors is provided for didactic purposes, as well as to suggest implications for social work practice and research.  相似文献

ABSTRACT

With dramatic developments in the treatment of HIV/AIDS, life expectancy is increasing, resulting in more middle-aged and older adults living with this disease. Little is known about the problems, and especially the strengths, of those living and aging with HIV. Hardiness is used in the gerontological literature to describe and explain how people age successfully, despite traumatic life events and chronic diseases. Similarly, the concept of hardiness may be used to guide clinicians, researchers, and clients on how to age successfully with HIV. This article provides a review of hardiness in aging and HIV, and emphasizes its importance in facilitating successful aging with this disease. Conceptual and methodological concerns in studying hardiness and successful aging are addressed. Potential interventions and clinical implications for social work are posited for augmenting qualities of hardiness in people aging with HIV.  相似文献
