Transnationalism is one of the widely-used concepts in the study of contemporary migrations. This article assesses the value of a transnational approach to the study of post-war Irish migration, when over a million people left Ireland, the vast majority travelling to Great Britain. The principal conclusion is that informal personal networks transcended the borders of the nation state and the Irish in Britain existed in a transnational social space which spanned the Irish Sea and included fellow-migrants, and family and friends living at home.  相似文献

ABSTRACT

A recent prevalence of high visibility catastrophic events has garnered increased attention to process safety issues. While the use of Behavior-Based Safety interventions demonstrate a reduction in workplace injuries by targeting employee behavior, we believe that process safety requires a greater focus on the behavior of leaders (e.g., creating and executing strategy). One effective method to begin targeting leader behavior for the improvement of process safety is to teach leaders about the principles of behavior, including ways by which the science may be applied within their own organizational models.  相似文献

A number of governments and public policy institutes have developed Quality of Life Indexes – statistics that attempt to measure the quality of life for entire states or regions. We develop 14 criteria for determining the validity and usefulness of such QOL indexes to public policy. We then review 22 of the most-used QOL indexes from around the world. We conclude that many of the indexes are successful in that they are reliable, have established time series measures, and can be disaggregated to study subpopulations. However, many fall short in four areas: (1) indexes vary greatly in their coverage and definitions of domains of QOL, (2) none of the indexes distinguish among the concepts of input, throughput, and output that are used by public policy analysts, (3) they fail to show how QOL outputs are sensitive to public policy inputs, and (4) none have examined convergent validity against each other. We conclude that many of these indexes are potentially very useful for public policy and recommend research to further improve them.  相似文献

An earlier study, based on data from Western countries, concluded that an international standard for life satisfaction could be stated as 75 ± 2.5 percentage of the measurement scale maximum score. This study presents a similar analysis based on data from countries representing all major geographic regions. It is reported that these data yield a more inclusive standard of 70 ± 5 percentage of scale maximum. While the major correlates of life satisfaction are found to be individualism and national wealth, the life satisfaction levels of some countries are distinctly anomalous in this regard. It is concluded that the narrow range of population data suggest that life satisfaction is held under homeostatic control. The anomalous levels of life satisfaction reported by some countries indicate caution in the interpretation of life satisfaction data as implying some desirable population state.  相似文献

Exposure Assessment of TSEs from the Landspreading of Meat and Bone Meal   总被引:1,自引:0,他引:1  
Recent changes in European legislation have meant that certain processed abattoir waste, which has been appropriately heat treated and ground to a specified particle size, can be spread on nonpasture agricultural land. This has opened the way for the potential landspreading of mammalian meat and bone meal (mMBM) derived from animals slaughtered for human consumption. This article reports on two separate case studies (Study 1 carried out in Great Britain (GB) and Study 2 carried out in Ireland) on the potential exposure to TSE infectivity following the spreading of abattoir waste (derived from animals slaughtered for human consumption) on nonpasture agricultural land. For Study 1, the average TSE infectivity on nonpasture agricultural land per year from sheep with scrapie was found to be higher (five orders of magnitude) than that estimated for BSE in cattle (3.9 x 10(-3) Ovine Oral ID(50)/ton of soil compared to 3.3 x 10(-8) Bovine Oral ID(50)/ton of soil). The mean estimate for BSE in sheep was 8.1 x 10(-6) Ovine Oral ID(50)/ton of soil. The mean level of infectivity in mMBM was assessed to be 1.2 x 10(-5) and 2.36 x 10(-5) ID(50)/ton of mMBM for Study 1 and 2, respectively. For Study 2 the spreading of mMBM was estimated to result in infectivity on nonpasture land of 1.62 x 10(-8) Bovine Oral ID(50)/m(3). The mean simulated probability of infection per year per bovine animal was 1.11 x 10(-9). Given the low infectivity density and corresponding low risks to bovines the spreading of mMBM could be considered a viable alternative for the utilization of mMBM.  相似文献

Two major predictors of subjective quality oflife (SQOL) in adults are known to beself-esteem and a sense of primary control.Moreover, secondary control is known to be animportant defence strategy when primary controlfails. This study aimed to determine whetherthese relationships also apply to children. Asample of 66 children aged from 5 to 12 yearswere compared on their use of primary andsecondary control and on their ratings of SQOLand self-esteem. SQOL was measured using theComprehensive Quality of Life Scale,self-esteem by using the CoopersmithSelf-Esteem Inventory, and primary andsecondary control were measured by codingchildren's responses to three short video clipsof children in stressful situations. It wasfound that younger children use more primarycontrol and less secondary control than olderchildren. However, five year olds were foundcapable of producing secondary controlstrategies. Contrary to expectation, primaryand secondary control did not predict eitherself-esteem or SQOL. However, self-esteempredicted SQOL as expected and no sexdifferences were found. These findingsemphasise important differences from the adultliterature and the reasons for this arediscussed.  相似文献
