The authors consider the optimal design of sampling schedules for binary sequence data. They propose an approach which allows a variety of goals to be reflected in the utility function by including deterministic sampling cost, a term related to prediction, and if relevant, a term related to learning about a treatment effect To this end, they use a nonparametric probability model relying on a minimal number of assumptions. They show how their assumption of partial exchangeability for the binary sequence of data allows the sampling distribution to be written as a mixture of homogeneous Markov chains of order k. The implementation follows the approach of Quintana & Müller (2004), which uses a Dirichlet process prior for the mixture. 相似文献

The primary purpose of this study is to typify the respondent strategies of the OECD countries based on the interconnected structure of income and employment guarantees. More specifically, this article seeks to typify welfare policies into four types (welfare-to-work, welfare emphasis, labour emphasis, market emphasis) based on the leniency of the pension system and active state intervention in employment security. With the resultant four types, this article then places them as the dependent variable while incorporating per capita GDP, aged dependency ratio, pension maturity level, union density, constitutional structure index and degree of decommodification as causal variables. Through this process, this article aims to derive the decisive variable for each type through qualitative comparative analysis. 相似文献

This paper examines the role of nonprofit organizations (NPOs) in the process of family policy formulation in eight member states and three applicant states of the European Union. Drawing upon interviews with representatives from the nonprofit sector, the author argues that the experiences of NPOs in family policy-making vary considerably between countries because of the way state–nonprofit relations operate. Social origins theory illustrates why these variations exist by pointing to broad societal influences on the nonprofit sector, but new empirical evidence presented here suggests that, in a particular policy field, other factors, such as the significance of the field on policy agendas, the strength of one particular organization in a specific cultural context, party ideology, and financial viability of the NPO, shape the role of organizations in the formulation of policies 相似文献

We compare husbands' and wives' views of the wantedness of their most recent pregnancy in the Philippines, a country where relatively high levels of unintended fertility persist. This research is an extension of earlier work that looked separately at individual men's and women's responses. We analyze survey data for 369 couples and find that those most at risk of experiencing a pregnancy that neither spouse wanted tended to be higher parity couples, those who were more fatalistic, those who were practicing Catholics who attended religious services frequently, and those among whom the husband was the sole breadwinner. Higher parity women and older women were also more apt to experience a pregnancy that was wanted by only 1 spouse. Women who had difficulty discussing sexual matters with their husbands were more likely than other women to have a pregnancy that their husbands wanted but they did not. 相似文献

党的形势政策观的价值取向,就是我党在分析形势进行政策活动时所指向的一定价值目标的活动过程。中国共产党在长期革命和建设实践中,总是以解放和发展生产力、代表人民群众的根本利益以及维护工人阶级的统治地位和阶级利益作为党的基本价值取向,它们同时也是党在分析形势进行政策活动过程中的基本价值取向。 相似文献

Abstract This article focuses on when and how states develop transnational policies. It presents a case study of a relatively small emigrant community, whose departure was not simply caused by poverty or crisis, but most recently by an economic and political debacle that questioned people's values and expectations. I focus on the state side of the equation and identify a shift in Argentina's policy after 2003, though also show how such policies came out of a long history of state intervention in population and migration and are now related to human rights concerns and the unfinished process of democratic consolidation. I argue that the state initiates political transnationalism, not migrants, and highlight the importance of some relatively unexplored factors in the understanding of the motivation, intensity and impact of the state's involvement, such as the characteristics of the emigrant community, the existence of specific political projects, the role of some domestic actors and processes, and the nature of international agreements. 相似文献

To ascertain the viability of a project, undertake resource allocation, take part in bidding processes, and other related decisions, modern project management requires forecasting techniques for cost, duration, and performance of a project, not only under normal circumstances, but also under external events that might abruptly change the status quo. We provide a Bayesian framework that provides a global forecast of a project's performance. We aim at predicting the probabilities and impacts of a set of potential scenarios caused by combinations of disruptive events, and using this information to deal with project management issues. To introduce the methodology, we focus on a project's cost, but the ideas equally apply to project duration or performance forecasting. We illustrate our approach with an example based on a real case study involving estimation of the uncertainty in project cost while bidding for a contract. 相似文献

美国对华贸易虽以保持稳定的经贸关系为基础,但迫于国际政治需要和国内的集团利益,还存在许多不确定性。因此,中国应当从宏观上对中美经贸关系拓展战略性思维,加强开展商务外交,构建和谐的国际经贸新秩序;从微观上,完善政府的商务职能,加强企业国际化能力,充分发挥行业协会的作用,多方面促使中美贸易朝正常化方向发展。 相似文献
