This study examined the mediating influence of protege‐initiated mentoring relationships on the relationship between personality and situational characteristics and mentoring received. Data were obtained from Hong Kong Chinese graduate employees (N=184) in their early career stage. Results of the regression analysis showed that protege‐initiated mentoring relationships mediated the relationship between the personality (extraversion) but not the situational (individual development culture and opportunities for interactions on the job) characteristics and mentoring received. In other words, extraversion was indirectly related to mentoring received through protege‐initiated mentoring relationships but individual development culture and opportunities for interactions on the job were directly related to mentoring received. Additionally, opportunities for interactions on the job indirectly influenced mentoring received through protege‐initiated mentoring relationships. Limitations of the study, implications of the findings and directions for future research are discussed. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

Framework for integrating indigenous and scientific knowledge for disaster risk reduction 总被引:2,自引:0,他引:2
A growing awareness of the value of indigenous knowledge has prompted calls for its use within disaster risk reduction. The use of indigenous knowledge alongside scientific knowledge is increasingly advocated but there is as yet no clearly developed framework demonstrating how the two may be integrated to reduce community vulnerability to environmental hazards. This paper presents such a framework, using a participatory approach in which relevant indigenous and scientific knowledge may be integrated to reduce a community's vulnerability to environmental hazards. Focusing on small island developing states it presents an analysis of the need for such a framework alongside the difficulties of incorporating indigenous knowledge. This is followed by an explanation of the various processes within the framework, drawing on research completed in Papua New Guinea. This framework is an important first step in identifying how indigenous and scientific knowledge may be integrated to reduce community vulnerability to environmental hazards. 相似文献

This paper reports on an examination of data on how local residents in Tuscaloosa, a mid‐sized city in the state of Alabama, United States, responded to Hurricane Ivan of September 2004. The evaluation revealed that an integrated connection to community‐level communication resources—comprising local media, community organisations and interpersonal networks—has a direct impact on the likelihood of engaging in pre‐hurricane preparedness activities and an indirect effect on during‐hurricane preparedness activities. Neighbourhood belonging mediated the relation between an integrated connection to community‐level communication resources and during‐hurricane preparedness activities. Neighbourhood belonging was determined to increase the likelihood of taking preparedness actions during Hurricane Ivan, but not prior to it. In addition, we discovered an interesting pattern for two different types of risk perceptions: social and personal risk perceptions. Social risk perceptions increase the likelihood of taking preventative steps before a hurricane while personal risk perceptions are positively related to engaging in preventative action during a hurricane. 相似文献

Community participation is becoming increasingly popular within the field of disaster management. International disaster policies, frameworks and charters embrace the notion that communities should play an active role in initiatives to identify vulnerabilities and risks and to mitigate those dangers, and, in the event of a disaster, that they should play a proactive part in response and recovery (see, for example, UNISDR, 1994; The Sphere Project, 2004; United Nations, 2005). A number of studies have investigated the participation of communities in disaster preparedness and mitigation efforts (see, for instance, Scott‐Villiers, 2000; Andharia, 2002; Godschalk, Brody and Burby, 2003), There is, however, limited reflection on the challenges to ensuring participation in the operational context of disaster response. This paper draws on a study of the policy and practice of participatory damage assessment in Fiji to identify and discuss the barriers to formal implementation of community participation in a post‐disaster context. 相似文献
