The authors carried out, on the basis of data resulting from the DHS-MICS 2011, an analysis using the binomial logistic model. It comes out from this analysis that the significant explanatory variables are the age (which plays at the same time the role of variable of control), the religion, the ethnic group, the size of the household, the relationship with the head of household, the educational level (of the woman and the husband/partner), the occupational status of the husband/partner, the household's standard of living, and the marital status. According to the results obtained, it would be important to set up policies intended to reinforce the professionalization of the young woman and to fight against the sexist sociocultural norms and practices advocating the "sexual division" of labor.展开更多

Aim: The aim of this study was to examine the incidence of stroke in women, born outside as well as in Sweden. Furthermore, the aim was to examine how socio-economic factors, smoking, and physical activity could modify the risk for stroke. Method: Data from the “MalmöDiet and Cancer Study” was used for the analysis. In total, 16,857 women were included (14,849 of them born in and 2,008 born outside Sweden), aged 45 - 73 years with a mean age of 57.4 years. Result. A significantly increased relative risk (RR) was found for the incidence of stroke for current smokers in both Swedish-born and migrant women. In Swedish-born women the RR was 1.98 (CI: 1.66 - 2.36) and for migrant women the RR was 1.83(CI: 1.13 - 2.96). The adjusted relative risk for the incidence of stroke in Swedish-born women performing moderate/high physical activity was RR 0.71 (CI: 0.61 - 0.84) and for migrant women it was RR 0.77 (CI: 0.49 - 1.20). The relative risk in relation to low socio-economic circumstances (SES) was significant only for Swedish-born women (RR 0.85 [CI: 0.73 - 0.99]). Among currently smoking Swedish-born women with a low SES the RR was 1.27 (CI: 1.03 - 1.57) in comparison with smoking migrant women, whose RR was 1.68 (CI: 0.92 - 3.09). Conclusion: No differences were found indicating that migrant women in this population had a higher risk as compared to Swedish-born women. However, migrant smoking women were more vulnerable to stroke compared to Swedish-born women. Physical activity was effective in reducing the risk of stroke among the total population and especially in the Swedish-born women. To increase physical activity in middle-aged women, in both migrant and Swedish-born women, is a highly recommended public health strategy.展开更多

This is reshaping the overall pattern of life custom, cultural production, consumption and trade in a world increasingly filled with changes and economic diversity. In an age of globalization, often ask questions and discussions concerning about successes and vitalities of nations. Globalization and technological revolutions race ahead and transform the world, and how to traces the real business to success. There are thousands of good examples where any nations have shown entrepreneurial talents and have succeeded. It is culture that principally explains, in many cases, or geographical pattern where some countries are developing more rapidly and more successfully than others. How to explain economic success of this nation's miracles or simple the secret is creative entrepreneurships? This paper explores the complex interactions between the geographic pattern from one side and cultural, technological and social aspects of entrepreneurship from other side which generates the dynamic processes of the world economy. In this era of transformation, creativity and knowledge entrepreneurship are powerful tools of fostering economic progress and development.展开更多

文摘The Second Belt and Road Forum for International Cooperation has ushered in a new phase featuring the joint promotion of a comprehensive,high-quality Belt and Road construction.Advancing the construction of a high-quality Belt and Road is based not only on the solid achievements of its six years of consolidation and practical cooperation,but also on the guidance of China’s initiatives and proposals,general recognition by the countries along the Belt and Road,as well as the support and recognition from international organizations like the United Nations.However,the uncertainty and instability found in the ever-changing international environment,the suspicion and strategic competition from extraterritorial major countries,and other concrete problems appearing during its construction over the past six years have also posed certain challenges that cannot be ignored.The direction of its high-quality development in this new phase involves China’s proactive selection to face the changing international environment and curtail suspicions from the outside world,as well as to resolve the difficulties and problems it encounters along the way in a timely manner,which will ensure the long-term sustainability of the Belt and Road.Achieving this goal calls for long-term system engineering,wherein China should continue to play a steering role,and the convergence of the interests of the countries along the Belt and Road so as to fuse these nations,each with their own respective resources,closely together by building a regional value chain.In such a closely-knit community,high-quality infrastructure serves as the backbone,while diversified financing institutions and functions serve as the arteries.Meanwhile,institutional building should also be emphasized,which will ensure that the goals for building a high-quality Belt and Road are fulfilled at different levels.
文摘Globalization and information technologies are new realities that have brought profound changes in lifestyles worldwide. This is reshaping the overall pattern of life custom, cultural production, consumption and trade in a world increasingly filled with changes and economic diversity. In an age of globalization, often ask questions and discussions concerning about successes and vitalities of nations. Globalization and technological revolutions race ahead and transform the world, and how to traces the real business to success. There are thousands of good examples where any nations have shown entrepreneurial talents and have succeeded. It is culture that principally explains, in many cases, or geographical pattern where some countries are developing more rapidly and more successfully than others. How to explain economic success of this nation's miracles or simple the secret is creative entrepreneurships? This paper explores the complex interactions between the geographic pattern from one side and cultural, technological and social aspects of entrepreneurship from other side which generates the dynamic processes of the world economy. In this era of transformation, creativity and knowledge entrepreneurship are powerful tools of fostering economic progress and development.
