There is a lack of research investigating Pacific peoples' gambling within a New Zealand context. In this paper, data about gambling activity (rather than problem gambling) are presented from the first data collection point for a cohort of mothers who are part of the longitudinal Pacific Islands Families study. The results indicate that gambling behaviour could be influenced by cultural differences. For example, Tongans are more likely to gamble than Samoans, and those who undertake traditional gift giving customs are likely to spend more money on gambling than those who do not. This paper identifies a need for research on Pacific peoples' gambling to acknowledge ethnic-specific cultural influences on gambling practices. 相似文献

In this paper we analyse—theoretically and empirically—how the degree of private versus public ownership of firms affects
the degree of rent sharing between firms and their workers. Using a particularly rich linked employer-employee dataset from
Portugal, covering a large number of corporate ownership changes across a wide spectrum of economic sectors over more than
20 years, we find that rent sharing is significantly higher in firms with a larger share of private ownership. Estimates from
our most preferred empirical specification suggest that an increase in the private ownership share of 10 percentage points
increases (on average) the rent-sharing elasticity by 0.0002. Based on a theoretical analysis that incorporates union-firm
wage bargaining and efficiency wage effects within the same modelling framework, this result cannot be explained by private
firms being more profit oriented than public ones. However, the result is consistent with a scenario whereby privatisation
leads to less job security for workers, implying stronger efficiency wage effects. 相似文献

Plants in cities must cope with various anthropogenic environments that differ from surrounding landscapes. Moreover, the differences in biotic and abiotic conditions among these habitats filter species with suitable traits and niche requirements. Here we aim to identify those attributes that promote species occurrence across and within urban habitat types of large cities. Species composition of spontaneously occurring vascular plant species was recorded in 1-ha plots in seven different urban habitat types in each of 32 European cities. Each species was characterized in terms of dispersal type, growth form, height, seed bank longevity, seed mass, selected leaf traits and ecological indicators including Ellenberg indicator values, Grime’s life strategies, and immigration pathways using information from available species-trait databases. For each species, total frequency of occurrence across all plots and habitat frequency of occurrence across plots of given habitat types were calculated and regression trees were used to relate them to traits and ecological indicators. The most frequently occurring species in the cities tended to be human-dispersed, nutrient-demanding plants that prefer drier to mesic soil conditions. These species do not possess the S-strategy and usually produce seeds of low mass forming short-term persistent seed banks. Habitat-specific responses were also revealed, indicating the effects of between- and within-habitat heterogeneity on trends in species performance in cities. Such patterns can be overlooked when differences in species occurrences in particular urban habitat types are not considered; thus, habitat-specific responses can resolve inconsistencies found when whole urban floras are analysed as a whole. 相似文献

The sociology of occupations and professions manifests a clear tendency toward the use of theoretical perspectives which emphasize considerations of power, social control and negotiation. This is most clearly articulated in several substantive areas within the field, notably occupational expansionism, intra-occupational relations, and the environmental context of occupations. A survey of research in these areas suggests some tentative generalizations. Emerging out of this perspective is a view of occupational roles as dynamic and shifting, responding to external groups, and at the same time exhibiting enough flexibility to permit individuals the opportunity to negotiate the parameters of their roles. 相似文献
