性向解释是在频率解释不能解决单个事件概率的情形下由波普尔提出来的。虽然波普尔的性向解释也没有解决为单个事件引入客观概率的问题,但与频率解释相比,它对概率论应用的情形提供了有用的扩展,并且“性向”这个术语并不仅仅适用于他自己的观点。由此,后期波普尔、米勒和费塞特发展了单个事例性向解释,吉利斯发展了长趋势性向解释。  相似文献

Bayesian acceptance sampling plans, which utilize prior information on the process variation, can be employed as an alternative to conventional types of plans for taking decisions on the disposition of submitted lots. A special type of double sampling inspection plans by attributes with small acceptance numbers using Bayesian methodology is presented in this paper emphasizing its significance over small acceptance number single sampling plans. The procedures for designing such sampling plans for specified degree of discrimination which would ensure protection to the producer and consumer are discussed with illustrations under the conditions for the application of gamma-Poisson distribution.  相似文献

This paper examines the implications for European music culture of the European Union’s (EU) Digital Single Market strategy. It focuses on the regulatory framework being created for the management of copyright policy, and in particular the role played by collective management organisations (CMOs or collecting societies). One of the many new opportunities created by digitalisation has been the music streaming services. These depend on consumers being able to access music wherever they are, but such a system runs counter to the management of rights on a national basis and through collecting organisations which act as monopolies within their own territories. The result has been ‘geo-blocking’. The EU has attempted to resolve this problem in a variety of ways, most recently in a Directive designed to reform the CMOs. In this paper, we document these various efforts, showing them to be motivated by a deep-seated and persisting belief in the capacity of ‘competition’ to resolve problems that, we argue, actually lie elsewhere – in copyright policy itself. The result is that the EU’s intervention fails to address its core concern and threatens the diversity of European music culture by rewarding those who are already commercially successful.  相似文献

本文将抽样调查资料与人口普查资料相结合,利用多种统计方法、多方案推算苏州市独生子女存量规模以及未来各年数量,并据此测算了未来各年政府可能的配套奖励性支出。研究结果表明:独生子女大规模进入婚育年龄将势必引起政策生育率的上升,未来各年政府用于独生子女家庭及其父母养老等计划生育政策奖励性支出将逐年增加.财政负担日益加重。建议政府对计划生育配套奖励政策适时进行调整,由现行的提供物质奖励向提供优质服务和社会保障转变。  相似文献

Using American Community Survey data from 2001, 2005, and 2010, this paper assesses the relationships between employment, race, and poverty for households headed by single women across different economic periods. While poverty rates rose dramatically among single-mother families between 2001 and 2010, surprisingly many racial disparities in poverty narrowed by the end of the decade. This was due to a greater increase in poverty among whites, although gaps between whites and Blacks, whites and Hispanics, and whites and American Indians remained quite large in 2010. All employment statuses were at higher risk of poverty in 2010 than 2001 and the risk increased most sharply for those employed part-time, the unemployed, and those not in the labor force. Given the concurrent increase in part-time employment and unemployment between 2000 and 2010, findings paint a bleak picture of the toll the last decade has had on the well being of single-mother families.  相似文献

This paper examines family interactions between mothers and children in single‐parent‐by‐choice (SPBC) families in Spain. The data is part of a larger multi‐sited ethnographic study focused on emergent family structures that examined families formed by women who began their family projects through adoption or assisted reproduction. Single‐mothers‐by‐choice formulate various socialization goals that are tied to the complexities of their non‐conventional family project. These goals are also realized in daily conversation, particularly when families talk about future events in their lives. Our findings expand existing family language socialization research in Western contexts, which has primarily focused on conventional two‐parent families, and invite developing a stronger dialogue between family language socialization research and current debates on changing kinship structures in post‐industrial societies. Este trabajo examina interacciones entre madres e hijos/as en familias de madres solteras por elección (MSPE) en España. Los datos provienen de una investigación etnográfica multi‐lugar más amplia centrada en modelo familiares emergentes que estudió a familias formadas por mujeres solas que han comenzado su proyecto familiar a través de la reproducción asistida o la adopción. La madres solteras por elección formulan varias metas de socialización que están ligadas a las complejidades y demandas de su proyecto familiar no convencional. Estos objetivos también se plasman en conversaciones cotidianas, especialmente cuando las familias hablan sobre eventos futuros en su vidas. Nuestros resultados amplían la investigación sobre socialización lingüística familiar en contextos occidentales, que se ha centrado principalmente en familias bi‐parentales convencionales, e invitan a desarrollar un diálogo más fructífero entre la investigación sobre socialización lingüística familiar y los debates actuales en torno a cambios en los patrones de parentesco en sociedades post‐industriales.
