Abstract

This study looks at the effect of current climate variability and projected future climate change to 2025 on New Zealand's energy industry (mainly electricity supply and demand) and at the wider economic implications of these effects. Electricity demand is modulated by climate largely through temperature, while electricity supply is modulated largely through rainfall and inflows to the major hydroelectricity‐generating lakes in the South Island. Six climate scenarios are examined with an energy model to determine the change in the demand for energy and the change in the composition of energy supply, especially with regard to the mix of electricity generation. The output from this model is then used as an input to a multi‐industry general equilibrium model of the New Zealand economy.

The modelling demonstrates that while the expected effects of projected climate change on the energy industry over the next two decades are reasonably significant, the flow‐on effects from the energy to the wider economy are negligible, albeit slightly favourable. Modelling of the effects of climate variability, which includes unusually cold years, unusually warm years, and variable precipitation, however, shows that unexpected adverse events do have a measurable economic impact, particularly if wage rates are inflexible. Export industries are particularly disadvantaged by higher energy costs, implying a need for adequate reserve generation capacity. Just how much reserve capacity is optimal is a topic for further research.

Climate change scenarios to 2050 and 2100 show much greater climatic effects than are expected over the next 20 years. These have not been modelled as the types and costs of electricity generation technologies that might become available beyond 20 years are extremely uncertain.  相似文献

Resumen

Este estudio fue diseñado para poner a prueba la hipótesis de reactancia-indefensión de Wortman y Brehm (según la cual los efectos producidos por la incontrolabilidad están mediados por la duración del evento incontrolable) en relación al funcionamiento corporal. Para ello, se eligió como principal variable dependiente el control de la respuesta electromiográfica de la musculatura frontal. Se utilizó un diseño factorial 3 (expectativa de control alta, baja y nula) X 2 (entrenamiento en incontrolabilidad corto y largo). Asimismo, se incluyeron medidas sobre «locus de control», estilo atribucional, percepción y estrategias de control. Los resultados obtenidos confirman parcialmente la hipótesis establecida y son discutidos dentro del ámbito de la Psicofisiologia Social.  相似文献

This article reports on how research activity helped describe and analyse ASW (Approved Social Worker) learning experience as well as acting as a catalyst for change and development in policy and practice in Northern Ireland. The paper contextualizes the study by outlining the legislation, the main features of the ASW role and the approach to ASW training in Northern Ireland, and by reviewing the literature on the efficacy and value of competence‐based learning. While the findings do not provide conclusive evidence that a competence‐based approach is inherently more effective than previous courses, they do indicate that candidates who were trained in this way were moderately more satisfied than those who had participated in non‐competence based programmes. The research also highlights the importance of the interrelationship between training, practice experience and support in developing and sustaining competence. The paper concludes with a review of the recommendations arising from the study and an analysis of the developments in training and regulations relating to practice experience and re‐approval of ASWs since publication of the research. The study is of contemporary interest given the proposed changes to the role of ASWs/Mental Health Officers in the context of the reviews of UK mental health law.  相似文献

This study investigates the liaison role in social work field education from the perspective of those presently working in that capacity at both the undergraduate and graduate levels from the United States and Puerto Rico (N?=?408). On average, undergraduate liaisons have more years of liaison experience, are more likely to be full‐time status, spend less time driving to sites, and devote more overall time to the role. Undergraduate program liaisons spend less time on problems and rate the quality of sites, field instructors, and overall levels of learning higher than graduate programs. Undergraduate liaisons report more institutional support, a higher level of value for field education in the curriculum, and a higher level of satisfaction with their liaison roles than graduate program liaisons.  相似文献

Abstract

This article describes a cultural mapping tool developed specifically for working with Aboriginal people experiencing mental health problems. The tool has broad scope, drawing from ecological and systems approaches. It will assist social workers to understand cultural and family obligations and build relationships with Aboriginal service users. Students learning about cultural diversity have expressed concern about asking culturally-sensitive questions. Australian human service workers typically state they feel inadequate in addressing Aboriginal culture in their practice approaches. The three components of the cultural mapping toolbox, (a) the social and emotional wellbeing cluster map, (b) the community and cultural diversity map, and (c) the migration map, provide social workers with a way of supporting a culturally connected lifestyle in contemporary society.  相似文献

Abstract

Aims: To apply the stress‐coping‐support perspective to the study of the effects of problem gambling in the family. Specifically, to examine the ways in which family members cope and the nature and sources of support they receive. To compare coping strategies of family members of gamblers with those of individuals living with other addictive behaviour in the family. Design: Cross‐sectional interview and questionnaire study of close relatives of problem gamblers. Participants: Sixteen close family members of gamblers from separate families, mainly parents and partners. Data: Semi‐structured interview; adapted version of the Coping Questionnaire (CQ). Findings: Data from the CQ and qualitative analysis of interview data suggested considerable use of ‘engaged’ (specifically controlling) ways of attempting to cope with such problems, comparable to the use of such strategies by relatives of people with alcohol or drug problems, but little use of ‘tolerant‐accepting’ and ‘withdrawal’ ways. Interview data on the support received (or not) by family members confirmed previous research showing that relatives of people with addiction problems often feel unsupported, but particularly appreciate positive emotional and practical support for themselves and their problem gambling relatives. Conclusions: The stress‐coping‐support perspective, previously applied to families with alcohol and drug problems, also offers an appropriate framework for understanding problem gambling and the family.  相似文献

Abstract

A growing literature indicates that organizational and work demands place pressure on the partners and families of volunteer workers as it does on paid workers. This study evaluated a conceptual model integrating work–family conflict and stress crossover theoretical frameworks, to investigate the mechanisms by which emergency service volunteer work, specifically, predicts outcomes for the partners of volunteers. Matched data from 102 couples in which one partner was an Australian emergency services volunteer – firefighter, ambulance officer or emergency rescue volunteer – were analysed using structural equation modelling analyses. Findings suggested that one mechanism by which inter-role conflict related to partner adjustment was through elevated withdrawn marital behaviour and decreased intimacy reported by the couple, which indirectly affected partners’ distress. This finding regarding withdrawn behaviour appears to be novel and may also be applicable to paid workers. Alternative mechanisms involving role overload and angry marital behaviour were not supported. These findings extend limited research which has adapted organizational theory to understand processes affecting volunteer workers, and advance conceptual accounts of the mechanisms through which the partners and families of workers are impacted by inter-role conflict.  相似文献
