The ability of managers to identify and interpret challenges in the external environment is one of the micro-foundations of dynamic capabilities. The underlying literature on strategic issue interpretation suggests that interpreting environmental challenges as opportunities rather than threats is more likely to lead to proactive and innovative responses, but there are also potentially positive effects of threat interpretation, for instance high levels of commitment and risk-seeking behaviour. In this paper, I use the context of climate change to explore the link between threat interpretation and innovation in more detail. I use exploratory cluster analysis and illustrative case studies to develop a set of propositions to explain when threat interpretation can in fact encourage innovation. I identify two ethical mechanisms that positively mediate the relationship between threat interpretation and innovation: enlarged concept of responsibility to society and moral legitimacy. The paper contributes to the literature by identifying the importance of ethics in linking managerial interpretation to innovation, particularly in the context of global environmental and social challenges.  相似文献

Social scientists and rural development interventionists inTanzania and in Sub-Saharan Africa depend mainly on conventionalsample surveys; in part this is a legacy of their basic training.Participatory rural appraisal and intervention approaches offera varied range of methods. We ask ourselves whether the resultsfrom participatory, rapid appraisals are conflicting and differentto those from sample surveys? This paper compares results ofa Rapid Participatory Rural Appraisal (PRA) with a conventionalsample survey. These surveys were conducted at the end of 1995and mid-1996 respectively, to establish socio-economic well-beingranks in Njombe district. A comparison of results shows thatthe well-being ranks established using PRA are valid and theapproach is reliable. The three qualitatively established well-beingranks differed empirically in many socio-economic indicators.These include resource endowment, labour force size, agriculturalland, livestock ownership, forest woodlot management, perceptionof food insecurity, technological advances in agricultural productionand natural resource management systems. Results show that thelow well-being group and female-headed households are disadvantaged.The goal of the Hifadhi Ya Mazingira-Njombe project is to developenvironmentally sustainable crop and livestock husbandry practicesin the district. The well-being ranking exercise has strongimplications for the project's strategy. We discuss the adoptedmethodology and implications. The paper recommends that developmentprogrammes and workers in Tanzania and Sub-Saharan Africa oughtto extend their approaches. It is time to include more of theparticipatory, relatively rapid rural appraisal and interventiontechniques. Benefits that they may accrue are time saving, lowercosts, quality information and stakeholder involvement.  相似文献

Injury indicators can be used to give policy makers an estimate of the scale of injuries and their long-term effects. They can help compare injury levels in different areas and countries and can be used to help measure the effectiveness of interventions. Work on severity related indicators is promising. However there are no perfect indicators to date as many are hampered with difficulties in case definition and under reporting. For example, mortality rates are affected by improvements in care even if the incidence of an injury remains the same, the abbreviated injury scale (AIS) takes 10-20 minutes to code and so is not used in health service databases, surveys have problems with recall bias, definition of injury and response rates. If we accept that we need to make the best out of imperfect indicators and imperfect data then we should use multiple sources of data and accept that no one indicator can be used universally but needs to be selected for the purpose. For example, one possible new indicator of the incidence of non-fatal injury might be fracture data in the emergency department. Fractures are painful and so nearly always end up with a hospital attendance. This might give a means to compare incidence of non-fatal injury in different areas and countries. In conclusion, we need injury indicators to progress in injury prevention. Imperfect indicators can be used for targeting and evaluating interventions as long as we know and adjust for their limitations.  相似文献

We show how changes in the educational composition of the labourforce affect both the level and the behaviour over time of aggregateunemployment series. We also demonstrate that if it had notbeen for such changes, the US unemployment series would look'European' since the within-group unemployment series all havethat same appearance. We derive a natural-rate model of unemploymentfor two education groups, providing microfoundations for inter-groupdifferences in wages and unemployment, and evaluate its plausibilityin light of microeconomic evidence.  相似文献

Social security is based on the belief that all citizens should be protected by the state against the main vicissitudes of life: old age, unemployment, disability and sickness. The success of welfare programmes internationally in improving poverty, income distribution and unemployment is appraised. Income maintenance in South Africa, which is discriminatory and ineffective in meeting real human needs, is examined. Although welfare should not promote dependence, neither should it be so hard to come by as to punish the poor.  相似文献

On the efficiency of stock-based compensation   总被引:5,自引:0,他引:5  
When the market can observe the profitability of all projectswith equal precision, then with stock compensation (i) the weighton any given project in managerial compensation is independentof the marginal productivity of effort in the project; (ii)the projects that are the noisiest indicators of managerialeffort receive the most weight in compensation; and (iii) investorshave the greatest incentive to collect information about projectsthat are the noisiest indicators of managerial effort.  相似文献

Quality of life has been measured in many different ways for patients with chronic medical conditions. What is unique about the approach used here is that it uses suicide rates as a relatively objective measure of quality of life within the population of dialysis patients. Using a Heckman selection model, we estimate the relative suicide rates across patients undergoing both hemodialysis and peritoneal dialysis. Our empirical results show that patients on hemodialysis have relatively lower suicide rates after controlling for other factors. Specifically, our results indicate that 141 fewer suicides will occur for every 1,000 patients shifted from peritoneal to hemodialysis. Prior estimates of the higher costs of the latter modality yield an estimated expenditure of $42,043 per suicide avoided.  相似文献
