Mortality trends in the USSR from the middle of the nineteenth century to the present day are analyzed, with a focus on changes in life expectancy. The authors note that life expectancy increased up to 1964-1965, declined subsequently, and stabilized during the 1980s. Life expectancy has again started to rise since 1985. More detailed analyses of mortality differentials by sex and age and for the rural and urban populations are included. (SUMMARY IN ENG) 相似文献

数字化和人工智能在很大程度上作用于刑法中的罪责并改变了个人责任的基本概念。对于人类与机器人和人工智能系统之间的合作,要在个案中详细地审查:机器如何参与决定的作出,人类的行为空间如何发挥作用,以及个人的罪责是否被阻却或至少被极大地减轻。完全或在部分范围内让机器作出决定,会对罪责概念以及进一步对刑事责任产生许多问题,包括过失犯的预见可能性、客观归责、不当行为的可证明性等。在刑法上进行新的调整可能是有必要的,这涉及罪责、可归责性、可证明性和量刑,同时必须寻找刑法以外的其他解决方案,以持续防止数字化和人工智能系统对刑事责任的扩散。 相似文献

Bohning R 《The International migration review》1991,25(4):698-709
Migrant workers are less protected than nationals against the actions of states and employers. These workers therefore require special global protection of their rights while employed in countries other than their own. Accordingly, the UN International Labor Organization (ILO) is constitutionally charged with developing international measures to protect the interests of migrant workers from developing countries. The ILO, however, had little involvement in molding the International Convention on the protection of the Rights of All Migrants Workers and Members of their Families, adopted by the UN General Assembly in 1990. Instead, final adoption of the Convention stems largely from developing state dissatisfaction with the former 1975 ILO Migrant Workers Convention No. 143, and Mexican and Moroccan government machinations outside of the ILO in support of modifications. Convention No. 143 threatened to sever employment opportunities and hard foreign exchange remittances in North America and western Europe from illegally employed immigrant workers from developing countries. By working in the UN outside of the ILO, developing nations would enjoy automatic majority, and greater potential for success in reforming the Convention. Soon, developing nations squelched a delay tactic proffered by the Swedes, and succeeded in bringing the UN General Assembly to adopt resolution 34/172 in December 1979, which led to the establishment of an Open-Ended Working Group. This group then elaborated the 1990 Convention over 19 sessions. At the expense of the ILO and more developed nations, developing nations successfully challenged and changed the international order to benefit their peoples and national economies. Finally, the paper considers the interests of immigrant businesspeople and asylum seekers during or immediately upon entry to a foreign country, who are not specifically covered by the Convention. While the university of international humanitarian law suggests that businesspeople be included in the Convention, changes to the Convention will probably not be forthcoming. As for asylum seekers waiting for either refugee status or an interim-term engagement for work, the sensitive nature of this topic in certain countries precludes the adoption of inclusive documentation. 相似文献
