The vast heterogeneity among nations in terms of economic and demographic characteristics is evident, despite being overlooked in some global studies. In this heterogeneity, it is possible to identify some distinct aggregate classes differing at some very fundamental level: developing (South) nations and developed (North) nations may have very different, asymmetric problems, goals and structures. This study investigates these two distinct groups of socio-economic systems, as they interact in a context of global sustainability. We identify population, economic growth, welfare gap, energy supply and pollution as key issues and analyze them using a systems perspective. A dynamic feedback model, which discriminates the two groups of nations, is constructed to study the dynamics of variables related to the above key issues. The model is tested using extensive data between the years 1980-2005. According to the reference behavior covering the period 1980-2050, it is not viable to close the welfare gap between North and South, given the current prevailing non-renewable-resource-based growth system. A non-renewable-resource-based system adopted by the economic system of growing South would take the global system even closer to its limits. It is observed that indicators like reserve-to-demand ratio fail to provide reliable signals for a timely transition to alternative resources, and a very serious economic recession due to resource scarcity is likely to develop in the next couple of decades. By coupling the demographic and economic dynamics, it is shown that an economic slowdown due to a resource scarcity may have a dramatic widening effect on the already existing welfare gap. Scenario and policy experiments verify the widely accepted importance of stabilizing the population growth in South, transition to alternative energy resources, and investment support to the South in this transition simultaneously in order to reduce the welfare gap between the two blocks. It is observed that enthusiastic targets for an energy transition may have a serious negative impact on the welfare level experienced in South, whereas an energy transition in South supported by North seems to have the most desirable outcome regarding the welfare gap. 相似文献

I analyse the role of ethnic and native human capital – defined, respectively, as the average years of schooling of ethnic groups and of natives within a specific region – and of ethnic concentrations in the educational attainment of second-generation immigrants in Germany. Compared to natives’ children, parents’ education has a small and insignificant effect on second-generation immigrants’ education. Ethnic concentrations have a negative effect, while ethnic capital is insignificant. The effect of native capital, too, is insignificant but much larger in magnitude than the effect of ethnic capital. For women, mother’s education is relatively more important. For men, ethnic concentrations constitute a stronger impediment to educational attainment than for women. 相似文献

Persuading users to try new technologies continues to be a problem confronting organisations and technology vendors alike. To better understand the process of new technology trial and adoption, several theoretical models have been proposed, of which the Technology Acceptance Model has gained significant support. However, research concerning tangible extrinsic rewards has not been explored. The primary goal of this research is to study the impact of tangible extrinsic rewards on various aspects of an intention to engage in an initial trial of a new technology. The theoretical model was tested on 284 students as subjects in a trial of a new technology. Results suggest that such incentives may be effective in increasing the behavioural intention to try a new technology. Results also identify that when incentives are provided, perceived ease of use and usefulness are the primary drivers towards intentions to try a new technology. 相似文献

This mixed methods case study discusses how the introduction of new technology changed the work of departmental administrators at a Swedish university, drawing on Cockburn's theories on gender and technology, viewing organisations as fields of contestation. This paper argues that jobs seem more fragmented with less discretion, as a result of computerisation. However, time saved by a new division of labour enabled by digitalisation has increased the possibilities for specialisation and job crafting. This new division of labour also led to increased tensions between academics, administrators and management. As the risks and possibilities connected to computerisation are matters of social relations, as much as being governed by technology, this paper adds to the debates on work and technology by exploring the complexity of social relations at work place level experienced by this overlooked group at the periphery of the managerial and academic power centres in academia. 相似文献
