A survey of HIV/AIDS clients in Botswana, Africa, all of whom were receiving supportive counselling, was conducted. A total of 328 volunteer clients from randomly selected sites completed the survey related to client perceptions of counselling helpfulness, outlook on life, satisfaction with goal setting in counselling, experience of social stigma, and acceptance by family and others. Overall, clients were very positive concerning the benefits received from counselling, their relationship with their counsellor, the goal setting process, their family/friends support system and their present quality of life. The majority of clients did, however, indicate some level of feeling stigmatized by being HIV-positive. Additional major findings indicated that clients with family incomes of less than 10 K pula per year (around US$1 k) were less positive about their counselling and related experiences than were those with higher levels of family income, with the exception of social stigma where lower family income was associated with less perceived social stigma. Clients reporting counselling sessions lasting more than 15 min were generally more positive in their reactions to counselling and related experiences than were clients reporting sessions typically lasting 15 min or less. A discussion of the findings, along with recommendations for areas needing further study and attention, is provided.  相似文献

The aim of this paper is to present a reliability modeling and analysis of a two-unit system of a continuous casting (CC) plant. Real maintenance data of a steel production plant have been used for the purpose. Three types of failures were noted: repairable, replaceable and reconditioning/reinstallation. The two-unit system is operating in parallel, on full-reduced installed capacity. Upon the unit failure, an inspection is carried out to decide the type of maintenance task to be performed. Optimized reliability indices of the plant such as mean time to system failure, availability, expected busy periods of the repairman for various maintenance tasks, expected number of visits by the repairman, expected number of repairs, replacements and reconditioning/reinstallation are obtained. Semi-Markov processes and regenerative point techniques are used for the analysis. Profit incurred to the CC plant is also evaluated and related graphs are plotted to demonstrate the results.  相似文献

The first purpose of this study was to examine contemporaneous and longitudinal associations of maternal and paternal measures of family functioning with observational and self-report assessments of sibling conflict. The second purpose was to determine whether the ways in which families attempt to solve siblings' problems are associated with contemporaneous and longitudinal assessment of sibling conflict. The results indicate that paternal equality of treatment and family harmony during family discussions about sibling problems, as well as parents' perceptions of family cohesiveness, are associated with lower sibling conflict levels.  相似文献

In November 2012, 300 students came together in the Media School at Bournemouth University in the UK to report the US Presidential Election. Over the course of 10 days, students published 176 articles on a rolling news website, garnering more than 20,000 hits. On election night itself, students produced 10 h of live coverage on both TV and radio, airing 30 pre-recorded video packages and 35 pre-recorded radio packages. This experiential project adopted a so-called ‘live case’ methodology that encapsulated a high degree of application and a certain level of structure, which allowed for the ‘variety and uncertainty’ or reality to intervene. It also empowered and enabled students to reflect on and evaluate their individual experiences in light of their own learning styles. This paper will discuss the challenges and successes experienced during this experiential project, and will provide a nine-step guide on how others could replicate a similar project.  相似文献

A recent large scale educational aid program to the Philippines included the retraining of secondary chemistry teachers. Teachers were introduced to new content and to alternative teaching strategies. An initial resistance to change arose as it was perceived that the new approaches did not take into account very limited school facilities and very large teaching groups. The lecturing style of teaching, which predominates at all levels throughout the country, was seen as the most effective method to handle overwhelming classroom problems. Resistance was overcome after alternative teaching styles were modelled. This paper gives an overview of the aid program and outlines the introduced teaching strategies. It contends that Asian teachers have been largely unaffected by western educational aid due in part to the fact that such aid is rarely accompanied by the modelling of introduced strategies. Specialisations: primary teacher education, primary mathematics, pre- and in-service science education.  相似文献

Biotechnology has opened unprecedented avenues for exploring biological systems. One of the key techniques in genetic engineering is gene transfer, which involves transfer of recombinant DNA into plant cells to generate transgenic plants. Genes and genomes from a wide range of organisms are being manipulated for the benefit of mankind. Application of genetic engineering in agriculture has produced significant achievements such as yield improvement of major food crops.  相似文献

Abstract

This paper explores a proposal for an off-line e-learning platform that will provide a bridge for digitally unconnected students and educators to join the contemporary information and communications technology (ICT) intensive world. Individual remote and unconnected learners face a chicken and egg problem for engagement with contemporary e-learning offerings. Without connectivity, remote learners have no way of engaging with now common ICT intensified learning materials that are intended to teach them how to engage in an ICT intensive world! The paper takes systems approach to developing a solution that will fit into the world we have, and not one we wish we had in terms of infrastructure, economics and skills available in remote and developing regions. Digital learning courses are placed onto a portable e-learning environment that is not reliant on a constant network connection to function but retains interactivity, analytics and the ability to synchronise data with an educational institution when a connection is found.  相似文献
