Financial capability is receiving increasing interest among policy makers, who wish to reduce problem debt and welfare dependency and increase savings and general skills. We examine whether financial capability has impacts on psychological health independent of income and financial resources more generally using a nationally representative survey. Data from the British Household Panel Survey 1991-2006 are used to construct a measure of financial capability, which we relate to respondents’ psychological health using the 12-item General Health Questionnaire. Estimates from within-group panel data models indicate that financial capability has significant and substantial effects on psychological health over and above those associated with income and material wellbeing more generally. For men, having low financial capability has an effect larger than that associated with being unemployed, while for women it is similar to that of being divorced. Furthermore having low financial capability exacerbates the psychological costs associated with unemployment and divorce, while high financial capability reduces these costs.  相似文献

This article examines the effectiveness of current risk management practices to reduce project risk using a multinational, multi‐industry study across different scenarios and cultures. A survey was administered to 701 project managers, and their supervisors, in seven industries and three diverse countries (New Zealand, Israel, and Japan), in multiple languages during the 2002–2007 period. Results of this study show that project context—industry and country where a project is executed—significantly impacts perceived levels of project risk, and the intensity of risk management processes. Our findings also suggest that risk management moderates the relationship between risk level and project success. Specifically, we found that even moderate levels of risk management planning are sufficient to reduce the negative effect risk levels have on project success.  相似文献

Abstract

There has been a lot of talk, discussion (and even buzz) on the Internet and in the library world recently on the whole issue of linked data and what it may mean, accomplish, and even change in the Internet and library worlds. This article will attempt to clarify what linked data is, some of the issues surrounding it, and explore some possible implications.  相似文献

Personality and organizational health: the role of conscientiousness   总被引:1,自引:0,他引:1  
Organizational health research identifies processes through which the work environment and individual differences combine to influence both individual and organizational outcomes. This study investigated the contribution of conscientiousness to organizational health. Research in the areas of occupational stress, work performance, and organizational climate was used to develop a framework for integrating different elements of organizational health. Within this framework, the work environment was assessed by perceptions of workload and role clarity ; individual well-being was assessed by psychological distress and job satisfaction ; and behaviour important for organizational success was assessed by contextual performance. Conscientiousness was investigated within the framework using self-reports from a sample of 104 Australian employees. Conscientiousness directly influenced contextual performance but did not influence well-being or perceptions of the work environment. Conscientiousness also reduced the impact of role clarity on both psychological distress and job satisfaction. The role of conscientiousness in a comprehensive model of organizational health is discussed.  相似文献

In the 1990s, the Jewish population of South Africa declined at an unprecedented rate in marked contrast to Jewish populations in other English-speaking countries.
Possible explanations include fear of political instability and political violence, deteriorating economic conditions and prospects, fear of directly discriminatory government policies, rising violent crime rates, and more permissive immigration policies in desirable destination countries.
All but the last of these factors appear to have played some role. However, only changes in violent crime rates provide an explanation for the unprecedented surge in net emigration, persisting even after a successful political and economic transition to majority black rule under moderate African National Congress governments.
Changes in crime rates also provide the most satisfactory explanation for related changes in internal migration patterns.  相似文献

Two sets of items from Albrecht et al. (1986) are used to examine small town residents’ attitudes about the environment and the economy. One scale measures a general growth ethic while the other measures attitudes concerning urban growth. Concern over the environment and the economy are assessed with items drawn from Blocker and Eckberg (1989). Results indicate that environmental concerns are a stronger influence on growth attitudes than are economic considerations and that certain sociodemographic variables are weakly associated with this tendency. In the small town population studied, which is in the process of making decisions about growth, environmental concerns play a stronger role in influencing attitudes about growth than do concerns over the economy.  相似文献

Most travel behaviour studies that seek to promote cycling define market segments based on socio-demographics, travel mode use or attitudes. They do not address the stages of change process in travel behaviour, whereas this information can be instrumental in influencing travel behaviour change. This paper adopts the stages of change model to identify potential cycling market segments and to analyse and profile each of the market segments based on socio-economic factors, current travel behaviour, attitudes, perceptions and motivations. A survey was conducted among 620 individual regular commuters in the city of Dar-es-Salaam. On the basis of cycling behaviour attitudinal-variable statements, as developed from the stages of change model, the survey data were classified in six different segments: pre-contemplation, contemplation, prepared for action, action, maintenance and relapse. The study revealed that the different segments have different needs and are motivated by different factors suggesting that they need to be treated in different ways. These market segments can have important implications for designing cycling policies and promotional strategies that best serve the needs of each segment. The results indicate that urban policies and marketing strategies which aim to promote bicycle use may first target the contemplation, prepared for action and action segments that are most motivated to change and willing to cycle.  相似文献

This article addresses the performance of the three largest Australian airports following their privatization. The airports represent cases of divestment of government business enterprises into privately-owned businesses each with differing ownership arrangements. The performances of the privatized airports are considered using financial data obtained from general purpose financial reports of the entities. There are significant implications for future divestment policies, including the value of divestment as a policy response in uncompetitive environments, the use of particular infrastructure investment models, and the nature of the linkage between ownership structure and financial performance.  相似文献

One of the basic functions of an MRP system is to issue rescheduling messages that urge the planner tospeed up or slow down open orders. It seems in practice that these messages are not used at all by planners. This is mostly due to the inaccuracy of MRP, that more or less ignores safety time, safety stocks and lotsize flexibility in the calculation of reschedule-in messages. Reschedule-out messages are usually ignored because planners do not see the value of the message. Other reasons for not adhering to rescheduling messages are a lack of maintenance of MRP parameters or simply the wrong use of the MRP function. In the future, MRP rescheduling functionality will be used even less than today, due to the changing role of MRP within the planning framework. With the uprise of finite capacity scheduling packages, MRP is being pushed one level upward in the planning hierarchy. This means that rescheduling functionalities for the short term will become completely obsolete in MRP systems.  相似文献
