Knowledge translation and exchange (KTE) is a process through which research evidence can more effectively inform decision making in policy and practice environments. A telephone survey of Canadian microbial food safety researchers was conducted in 2009 to examine aspects of researcher KTE activities with government policymakers. Overall, researcher awareness of and engagement in KTE activities was high, although engagement was mainly through end-of-research dissemination activities rather than throughout the research process (integrated knowledge translation) and engagement in some high-quality KTE activities was low. Government researchers were significantly more likely to engage in KTE activities with federal policymakers and did so with greater frequency than non-government researchers. 相似文献

Limited agricultural land potential, poorly integrated markets and low rural incomes are all interrelated problems for agricultural households in western China. Within the wide range of development options available, this paper focuses on the impact of forage-growing subsidies and reducing livestock feed trade barriers on agricultural household incomes and enterprise mixes in the Qingyang Prefecture of Gansu Province, China. A heterogeneous-agent model is used to assess the local consequences of these two policies. Data from a survey conducted in 2009 are used as inputs into the model. The results indicate that a simultaneous reduction in livestock feed trade barriers and an introduction of forage-growing subsidies lifts net household incomes by approximately 10%. Different scenarios have different impacts on incomes, land allocation decisions and grain purchases, with heterogeneity also found among household income responses. Livestock-development policies have the potential to lift household incomes however there are tradeoffs between income and grain self-sufficiency. 相似文献

The purpose of this paper is twofold. First, we try to identify whether women have different borrowing patterns from men when
trying to get into self-employment along with the factors that explain these different propensities. Second, we try to quantify
the impact of these differences in borrowing propensity on women’s willingness to become self-employed. The empirical analysis
is carried out on a sample of individuals drawn from the English Household Survey of Entrepreneurship, 2003. Our results show
that (1) women are less likely than men to seek external finance and that (2) gender differences in access to finance are
affecting adversely the transition into self-employment. 相似文献

To better illuminate aspects of stress that are relevant to the moral domain, we present a definition and theoretical model
of “moral stress.” Our definition posits that moral stress is a psychological state born of an individual’s uncertainty about
his or her ability to fulfill relevant moral obligations. This definition assumes a self-and-others relational basis for moral
stress. Accordingly, our model draws from a theory of the self (identity theory) and a theory of others (stakeholder theory)
to suggest that this uncertainty arises as a manager faces competing claims for limited resources from multiple stakeholders
and/or across multiple role identities. We further propose that the extent to which the manager is attentive to the moral
aspects of the claims (i.e., moral attentiveness) moderates these effects. We identify several consequences of managerial
moral stress and discuss theoretical, empirical, and practical implications of our approach. Most importantly, we argue that
this work paves an important path for considering stress through the lens of morality. 相似文献

Longitudinal panel studies of large, random samples of business start-ups captured at the pre-operational stage allow researchers to address core issues for entrepreneurship research, namely, the processes of creation of new business ventures as well as their antecedents and outcomes. Here, we perform a methods-orientated review of all 83 journal articles that have used this type of data set, our purpose being to assist users of current data sets as well as designers of new projects in making the best use of this innovative research approach. Our review reveals a number of methods issues that are largely particular to this type of research. We conclude that amidst exemplary contributions, much of the reviewed research has not adequately managed these methods challenges, nor has it made use of the full potential of this new research approach. Specifically, we identify and suggest remedies for context-specific and interrelated methods challenges relating to sample definition, choice of level of analysis, operationalization and conceptualization, use of longitudinal data and dealing with various types of problematic heterogeneity. In addition, we note that future research can make further strides towards full utilization of the advantages of the research approach through better matching (from either direction) between theories and the phenomena captured in the data, and by addressing some under-explored research questions for which the approach may be particularly fruitful. 相似文献

Policymakers need to know whether prediction is possible and, if so, whether any proposed forecasting method will provide forecasts that are substantially more accurate than those from the relevant benchmark method. An inspection of global temperature data suggests that temperature is subject to irregular variations on all relevant time scales, and that variations during the late 1900s were not unusual. In such a situation, a “no change” extrapolation is an appropriate benchmark forecasting method. We used the UK Met Office Hadley Centre’s annual average thermometer data from 1850 through 2007 to examine the performance of the benchmark method. The accuracy of forecasts from the benchmark is such that even perfect forecasts would be unlikely to help policymakers. For example, mean absolute errors for the 20- and 50-year horizons were 0.18 C and 0.24 C respectively. We nevertheless demonstrate the use of benchmarking with the example of the Intergovernmental Panel on Climate Change’s 1992 linear projection of long-term warming at a rate of 0.03 C per year. The small sample of errors from ex ante projections at 0.03 C per year for 1992 through 2008 was practically indistinguishable from the benchmark errors. Validation for long-term forecasting, however, requires a much longer horizon. Again using the IPCC warming rate for our demonstration, we projected the rate successively over a period analogous to that envisaged in their scenario of exponential CO2 growth—the years 1851 to 1975. The errors from the projections were more than seven times greater than the errors from the benchmark method. Relative errors were larger for longer forecast horizons. Our validation exercise illustrates the importance of determining whether it is possible to obtain forecasts that are more useful than those from a simple benchmark before making expensive policy decisions. 相似文献

Although various factors have been studied for their influence on consumers’ ethical judgments, the role of incidental emotions has received relatively less attention. Recent research in consumer behavior has focused on studying the effect of specific incidental emotions on various aspects of consumer decision making. This paper investigates the effect of two negative, incidental emotional states of anger and fear on ethical judgment in a consumer context using a passive unethical behavior scenario (i.e., too much change received). The paper presents two experimental studies. Study 1 focuses on the interaction of moral intensity (amount of change) and incidental emotion state in predicting the ethical judgment while study 2 investigates the underlying causal mechanism behind the process, using a mediation analysis. The results reveal a significant interaction between moral intensity and incidental emotion. Specifically, individuals in the state of incidental fear exhibit higher levels of ethical judgment as the moral intensity increases as compared to individuals in the state of incidental anger. Further, perceived control is found to mediate the relationship between emotional state and ethical judgment under higher moral intensity condition. 相似文献

This study investigates the impact of three relational benefits (i.e. financial benefits, human interaction benefits, preferential treatment benefits) on switching barriers, customer satisfaction, and behavioral loyalty for key accounts in the context of the air express delivery industry in Taiwan. Empirical results indicate that relational benefits impact switching barriers, switching barriers influence customer satisfaction and loyalty, and customer satisfaction effects loyalty. Findings also confirm most of the hypothesized moderating effects for relationship duration and transactional volume on the relationship between relational benefits and switching barriers. Specifically, long-term key accounts place greater emphasis on the human interaction and preferential treatment benefits. Key accounts that have less established relationships based on the length of business relationship place more importance on financial benefits. Financial benefits were found to have a positive influence on switching barriers only for low annual transactional volume clients, while both human interaction benefits and preferential treatment benefits have positive effects for both low and high transactional volume key accounts. 相似文献

We examine precautionary behavior, specifically compliance with environmental regulations, pollution abatement, and care spending, by firms facing two sources of insolvency risk. If poor profit or a liability triggers insolvency, then the firm forgoes a profitable future. The behavioral implications of this survival motive vary across firms. Firms for whom the principal insolvency risk is liability-related now choose precaution above the level chosen by the solvent firm. For firms whose primary insolvency risk is profit-related, the survival motive reinforces incentives for care below the solvent benchmark arising from the familiar judgment-proof effect. We also characterize how insolvency risks affect incentives to conceal adverse events linked to these choices, such as an accident or a regulatory violation. An understanding of these incentives is particularly important during recessionary periods when firms struggle to survive the downturn. 相似文献
