Modern work is frequently characterized by jobs where adaptive performance (AP) is crucial for employees to succeed in light of new or altered task demands. This recognition has fueled growing interest in AP as a dimension of workplace performance. To this point, however, research on AP has evolved from disparate perspectives and methods, resulting in fragmentation and a less than coherent knowledge base. This paper presents a comprehensive review of research studies regarding the nomological network of individual AP. In doing so, we synthesize the current knowledge base surrounding correlates of AP, elucidate current ambiguities, and suggest directions for future research efforts. We conclude that although the extant AP literature has amassed a critical body of studies linking various predictors to successful AP outcomes, much remains unknown, most critically regarding the implications of different methods of assessing AP, the effects of different types of changes in the task environment, the process of AP, and the steps organizations can take to foster AP among their employees. We hope that our synthesis and analysis paves the way for efforts to address these important questions. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Adaptive co-management and learning are paramount for integrated flood risk management. Relevant literature focuses on adaptation at the level of physical and societal systems. The level of projects and programmes is largely overlooked, but they comprise interventions that adapt our physical systems and they provide opportunities for learning to contribute to transitions of societal systems. This paper aims to increase understanding on how learning takes place and can be stimulated within a programme. The mixed-method case study of Room for the River, a €2.3 billion programme for flood risk management, shows that a programme can be organised using various governance arrangements to stimulate learning and be a means for adaptive co-management to deliver upon environmental objectives.  相似文献

Adaptation takes place in both private and public sectors, or as an interrelation between the two, and often under the realm of public regulation. Thispaper uses the Swedish and the Norwegian electricity grid sector, as providers of a vital public good under strict public regulation, to analyse reforms' effects on adaptive capacity in this area. The paper shows that transformational changes in both sectors during the 1990s shifted both the formal organisational structure (rules and regulations), as well as the organisational culture, in the direction of economic efficiency. These two dimensions individually reduced adaptive capacity to climate change, although differently in the two countries. However, the formal structure and organisational culture also yielded substantial influence on each other. This leads to the conclusion that when designing public regulations and implementing reforms, organisational culture must be considered in the design. Also the paper contests previous findings in the literature by showing that under given conditions there exist some substitution between the two dimensions in influencing adaptive capacity, implying that both dimensions should be included when analysing adaptation since analysing them in isolation is likely to lead to wrong conclusions.  相似文献

In conflict‐affected situations, aid‐funded livelihood interventions are often tasked with a dual imperative: to generate material welfare benefits and to contribute to peacebuilding outcomes. There may be some logic to such a transformative agenda, but does the reality square with the rhetoric? Through a review of the effectiveness of a range of livelihood promotion interventions—from job creation to microfinance—this paper finds that high quality empirical evidence is hard to come by in conflict‐affected situations. Many evaluations appear to conflate outputs with impacts and numerous studies fail to include adequate information on their methodologies and datasets, making it difficult to appraise the reliability of their conclusions. Given the primary purpose of this literature—to provide policy guidance on effective ways to promote livelihoods—this silence is particularly concerning. As such, there is a strong case to be made for a restrained and nuanced handling of such interventions in conflict‐affected settings.  相似文献

Since the Rio conference, many countries and organisations, including the environmental movement, bilateral and multilateral institutions have endeavoured to carry out activities related to the implementation of Agenda 21. These have mostly been done with or without other outcomes of the conference. Several environmental management and sustainable development agenda have been pursued to halt the continually degrading environment. Other programmes have concentrated on outburst of economic development at the expense of the environment and the worsening poverty especially in the South. This paper therefore seeks to examine a paradigmatic shift in environmentalism, emphasising the link between agenda 21 and sustainable livelihoods. It seems though the history of the environmental movement has been forgotten after the Rio conference by the whole world. This might probably be due to complacency with the results of the UNCED conference. However, it is now obvious that clear objectives to implement the results of UNCED are almost lacking with little or no proper supervision, and further threatening the existence of mankind. The environmental movement and associated milestones have had significant impacts on the current status of the global commons. Regionally in most of southern Africa, livelihood issues are in the forefront of efforts to sustain environmental resources, and minimising proximate causes of global environmental change.  相似文献

甘肃河西内陆河流域社会化水资源稀缺评价   总被引:2,自引:0,他引:2  
水资源稀缺是我国经济社会发展所面临的严重制约因素。水资源稀缺评价是水资源管理中最基础性的工作。借助Karshenas模型对资源利用同经济发展之间的关系进行了诠释;在界定水资源管理阶段的基础上。引入社会适应性能力概念。着重论述了其内在结构及其度量指标。从而将水资源稀缺问题拓展到了社会经济领域。强调社会资源在水资源稀缺评价中的作用。同时。建立社会化水资源稀缺指数。并以甘肃省河西内陆河流域五市为例进行了实证研究.结果表明:嘉峪关市由于相对较高的社会适应性能力。其社会化水资源稀缺程度指数的相对排序得到改善;而武威市则因相对较低的社会适应性能力。社会化水资源稀缺指数的排序有所降低;金昌市和张掖市尽管社会化水资源稀缺指数的相对排序没有变化。但由于考虑了社会适应性能力。水资源稀缺程度得到有效的缓解。社会化水资源稀缺指数更能如实反映水资源状况。社会适应性能力是一种重要的资源。对缓解水资源紧缺程度具有重要的作用。  相似文献

At the Earth Summit in Johannesburg in 2002, partnerships were touted as one of the key routes to sustainable development. But can partnerships really deliver improvements to rural livelihoods? This paper reviews one set of claimed partnerships, those between forestry companies and local individuals or communities, to assess the benefits, and the costs, to local livelihoods. Most arrangements between forestry companies and local communities are not equitable enough to be called partnerships, so the term “deal” is preferred. Positive local impacts of company–community deals include sharing of risks, better returns to land than otherwise possible, opportunities for income diversification, access to paid employment, development of new skills, upgrading of local infrastructure and environmental improvement. However, company–community deals have not yet proved sufficient to lift people out of poverty. They remain supplementary rather than central to income generation. Furthermore, while some deals have resulted in greater cohesion and organisation among community groups, there is as yet little evidence of substantial increases in community bargaining power. Ways forward to increase returns to communities (and to their counterpart companies) centre on moving towards more equal partnerships, by raising community bargaining power, fostering the roles of brokers and other third parties, and developing equitable, efficient and accountable governance frameworks.  相似文献

Some Lessons Learned from Public Health on the Process of Adaptation   总被引:1,自引:1,他引:0  
Lessons learned from more than 150 years of public health research and intervention can provide insights to guide public health professionals and institutions as they design and implement specific strategies, policies, and measures to increase resilience to climate variability and change. This paper identifies both some modifications to public health systems that may enhance adaptive capacity, and lessons drawn from the history of managing environmental and other threats in the public health sector that may have relevance for other sectors as they design approaches to increase their adaptive capacity to more effectively cope with climate variability and change. The views expressed are the author’s own and do not represent official US EPA policy.  相似文献
