The intradural sagittal diameter at the second cervical vertebra (SD/C2) of 62 SIDS cases was measured myelographically. This SD/C2 proved to be dependent on body size, body weight, and age. A clear, age-dependent difference is to be found in the primarily narrow spinal canal. This parameter (SD/C2), which is more precisely defined in adults on the basis of clinical, radiological, and autopsical findings is assumed to have the value of 0.5 cm in the first 2 months, 0.6 cm in the third month, and 0.65 cm in the fourth month. The resulting potential danger to infants is dependent upon their position. The SD/C2, was significantly decreased in extension as compared to a neutral posture. With consideration of the primarily narrow spinal canal in the infant, there is, according to our measurements, a potential hazard for the infant in any further, significant shortening of the SD/C2. This is independent of the width of the spinal canal under maximal extension. We found individual cases in which the SD/C2 was decreased by almost 50% from the normal value in neutral position. No correlation was found between the primary width of the spinal canal and the degree of luminal reduction upon extension. 相似文献

The demise of the USSR led to the collapse of its centrally organised retail system. With this collapse the supply of consumer goods dried up, especially in the remote parts of the former USSR. At the same time the advent of capitalism offered a new institutional framework for independent retail activities. In the Kyrgyz Republic, where the economic liberalisation followed strictly the Washington Consensus, a large number of small shops emerged in both urban and rural areas. This study analyses the reasons for this boom in retail start-ups as well as the constraints the mainly inexperienced merchants encounter. As will be shown, any success in retail activities depends greatly on the performance of other economic sectors. The main goal of starting a retail business is to minimize risks within the overall livelihood strategies of households in rural Kyrgyzstan. 相似文献

Innovation by users is now understood to be an important part of innovative activity in the economy. In this paper we explore the implications of adding innovation by users to existing models of social welfare that currently assume innovation by manufacturers only. We find this addition removes several inefficiencies, and that social welfare is likely to be increased by the presence of user innovation. Implications for policies that can impact users' freedom to innovate are discussed. 相似文献

Implementing Democratic Equality in Political Parties: Organisational Consequences in the Swedish and the German Pirate Parties 下载免费PDF全文
Nicole Bolleyer Conor Little Felix‐Christopher von Nostitz 《Scandinavian political studies》2015,38(2):158-178
This article theorises and empirically assesses some important intra‐organisational implications of maximising democratic equality in political parties both between followers and members and between members and elites. They include weak member commitment, passivity of the rank‐and‐file membership and – depending on party structure – high levels of internal conflict. To substantiate the arguments, two parties that implement principles of democratic equality in their organisations are examined: the Swedish and German Pirate parties. These cases show, first, that while organisational structures implementing norms of equality allowed them to rapidly mobilise a considerable following, the same structures systematically reduced their capacity to consolidate support in the longer term – a weakness that might eventually put these parties' survival at risk. Second, they show that differences in the extent to which subnational units provide a foundation for member mobilisation helps to explain variation in the level of internal conflict experienced by these parties. 相似文献
