Four years after its inception, Workcare, the Victorian Government's new workers' compensation scheme, has failed to live up to its promise. Recent reforms have concentrated on identifying groups responsible for the ‘rorts’ and cost ‘blowouts’ of the scheme. It is argued that although this sort of intervention might make economic sense, it continues a tradition of scapegoating individual workers rather than trying to analyse the complex workings of such schemes. Several of the assumptions underlying Workcare (and similar systems) are discussed in order to demonstrate the potential for failure in any benefits delivery system based on status rather than need.  相似文献

Despite a recognized need for a global mindset, opportunities for US business school students to gain hands‐on diversity training regarding intercultural issues remain rare. The reasons for this neglect include a lack of agreement on how to teach intercultural awareness and a paucity of faculty qualified to do so. In order to introduce intercultural education into a core business course, students were offered the opportunity to participate in an extra‐credit project that required the development of a proposal for an international joint venture and afforded them the chance to learn about each other while pursuing a superordinate goal of value to each. Thirty‐nine cross‐cultural teams were created, each of which had a partner from the US and a partner from a different country. Both quantitative and qualitative analyses revealed that the value of the project was closely related to the amount of learning that reportedly took place in both the business and cultural realms. Importantly, 73% of the students reported a strong interest in meeting people from different cultures as a result of participation in the project.  相似文献

Cities are highly modified environments in which the only areas that resemble natural landscapes are urban parks with low human population density. Attempts are frequently made to maintain high bird diversity in cities for aesthetic or educational reasons. However, it remains unclear whether local site characteristics are important in determining bird assemblage composition or whether simplification of the assemblage is an inevitable consequence of the changes associated with human population density. From May 1998 to December 1999, we undertook bird counts at 521 points in Porto Alegre, Rio Grande do Sul, southern Brazil. Our main goal was to understand the pattern of distribution of the bird species richness and density within the city and determine which variables most affect species assemblages. We recorded 132 species belonging to 43 families that are common in Rio Grande do Sul and obtained quantitative data on 121 species in survey sites. The two most abundant species (House Sparrow, Passer domesticus and Rock dove, Columba livia) were exotics. Analysis based on a reduced subset of 134 points surveyed in spring/early summer suggested that there was a North–south gradient in assemblage structure. Variation in assemblage structure was also affected by the number of trees, urban noise and human population density. However, human population density had a much smaller effect on richness and assemblage structure than variables subject to management, such as tree density and noise levels. These results suggest that complex communities may be maintained in densely populated urban areas of sub-tropical South-America given adequate urban planning.  相似文献

In an attempt to assess the national impact of anti-war protest, 15 major anti-Vietnam demonstrations occurring in the United States from 1965 through 1971 were analyzed for their effects upon Gallup public opinion survey data, American troop strength, and American munitions expenditures. While weak and short-term counterproductive effects appeared for two opinion indicators, an equally likely conclusion is that the demonstrations had little or no lasting impact whatsoever. The possible reasons for this finding, and its social implications, are discussed.  相似文献

As the overall U.S. population expands outward from the central city and core suburbs and as people age in place, more seniors will reside in suburban and exurban locations. This research seeks to determine whether older adults who live in areas with differing urban forms experience travel pattern variations under controls for other factors related to travel. We analyzed data from a telephone survey of a random sample of seniors aged 75 years and older and we employed a unique approach for establishing the urban form of their residential settings. The results show that urban form does influence travel patterns, including the number of trips and transportation mode, and suggest that the construction of compact, mixed-use communities where today's older adults can age in place may be part of the solution to addressing the mobility needs of our aging population.  相似文献
