构建社会主义和谐社会符合穆斯林的宗教信仰和根本利益

和谐是人类普遍的追求,是历史发展的永恒主题。实现社会和谐,建设美好社会,是世界上各民族、各宗教孜孜以求的共同社会理想。现在党和国家提出构建社会主义和谐社会,那么中国穆斯林这样一个信仰伊斯兰教的中华民族的组成群体如何在构建和谐社会的过程中发挥自己的作用,作出应有的贡献?本文以宗教和社会主义相适应,各民族携手共建和谐社会这个角度,从对和谐社会的理解和认识、伊斯兰教的和谐观、中国穆斯林应该为构建社会主义和谐社会这一共同目标而不懈努力三个方面探讨了伊斯兰教和穆斯林群众对构建社会主义和谐社会应有的认识、态度及实践。

养猪业是农村经济的重要组成部分,是畜牧业的主导。山西省地处黄土高原,有发展养猪业的资源优势。运用简单比较法,对山西省生猪产品在不同的饲养方式下与全国生猪产品在同种饲养方式下进行对比分析,揭示了山西省生猪产品生产在成本、价格、收益方面与全国同指标(平均)水平对比的优(劣)势状况,畜产品质量安全状况,并提出提升山西省生猪产品竞争力的对策建议。     

On Block Ordering of Variables in Graphical Modelling

Abstract.  In graphical modelling, the existence of substantive background knowledge on block ordering of variables is used to perform structural learning within the family of chain graphs (CGs) in which every block corresponds to an undirected graph and edges joining vertices in different blocks are directed in accordance with the ordering. We show that this practice may lead to an inappropriate restriction of the search space and introduce the concept of labelled block ordering B corresponding to a family of B - consistent CGs in which every block may be either an undirected graph or a directed acyclic graph or, more generally, a CG. In this way we provide a flexible tool for specifying subsets of chain graphs, and we observe that the most relevant subsets of CGs considered in the literature are families of B -consistent CGs for the appropriate choice of B . Structural learning within a family of B -consistent CGs requires to deal with Markov equivalence. We provide a graphical characterization of equivalence classes of B -consistent CGs, namely the B - essential graphs , as well as a procedure to construct the B -essential graph for any given equivalence class of B -consistent chain graphs. Both largest CGs and essential graphs turn out to be special cases of B -essential graphs.     

论柏拉图“理念”论及其对中世纪基督教神学之影响

在柏拉图思想体系中,“理念”论是其核心,它充分彰显了古希腊人追问永恒、绝对之终极本体的渴求,尤其是其“两重世界”的划分和“善”的理念之绝对先验性和超越性以及“回忆说”表现出的一种神学倾向,与中世纪基督教思想一拍即合,为基督教中彼岸世界与上帝之“合理”存在和“光照论”提供了思想根基。在一定意义上说,柏拉图的“理念”论为中世纪基督教神学的产生提供了理论的核心。     

Understanding decisions about child maltreatment

To understand how decisions are made in abuse/neglect cases by the child welfare system, the authors asked child welfare experts and protective service line workers to make decisions about actual child abuse and neglect cases on the basis of written summaries of the cases. Respondents included 27 experts and 103 line workers. Regression analyses found that workers and experts emphasized the same case characteristics in making their decisions, but the decisions were not well structured in the sense that they were not well predicted by case characteristics. Individual experts and workers varied widely in the decisions they made on identical cases. The authors conclude that decision making in the child protective system is inconsistent, with errors of two kinds: failing to remove children from their families when that is called for and removing children when it is unnecessary. Progress must be made in developing decision-making criteria that are consistent, preserve family integrity, and promote the well-being of children.     

Computing Probabilities of Type I Error and Type II Error of Sequential Bayesian Procedures for Testing One-Sided Hypotheses

In this article, it is shown how to compute, in an approximated way, probabilities of Type I error and Type II error of sequential Bayesian procedures for testing one-sided null hypotheses. First, some theoretical results are obtained, and then an algorithm is developed for applying these results. The prior predictive density plays a central role in this study.     

Diminished tradition of return? Transnational migration in Bolivia's Valle Alto

One‐fifth of the Bolivian population lives abroad, and transnational behaviour strongly links their villages with destination communities. In this article we address whether the increasing difficulty of return migration (owing to legal and geographic barriers) results in diminished social and economic remittances to the country of origin. Results from a questionnaire survey of 417 households in the Valle Alto area of Cochabamba Department in 2007 reveal that monetary remittances account for one‐half of the income of active migrant families (and one‐quarter of income overall), and that transnational cultural ties remain strong. However, after ten years of cumulated time abroad the intention to return to Bolivia drops markedly along with economic and some social remittances. Closer analysis reveals that time abroad reduces these ties through the mediating forces of family members abroad, legal status, and home ownership abroad.     

The Philippine Male Aging Survey

The aging male is fast becoming a global concern. The problem is predicted to become a major health issue that should be addressed immediately in order to prevent disability, morbidity, and, more importantly, mortality. As part of its commitment to increase awareness and create interest in the care of Filipino aging males, The Philippine Society for the Study of the Aging Male Foundation, Inc. (PhiSSAM), a multi-specialty society established in 2000, embarked on a survey among Filipino physicians to determine their knowledge, attitudes, and practices regarding male aging. Results showed that the majority of doctors (about 87%) thought that men may experience andropause. Most would diagnose patients based on symptoms alone, while only 20–30% used testosterone levels to make a diagnosis of andropause. Decreased libido and less strong erections were the symptoms very closely associated with low testosterone. Of those doctors responding, 89% agreed that andropause can affect the quality of a man's life as much as menopause can affect a female; only 38% had already prescribed/instituted treatment for andropause. Of the 62% non-prescribers, 58% said they were either very likely or fairly likely to institute treatment in the future if there were more clinical trials, more medical information, and more information on drugs. Major concerns on testosterone replacement therapy included prostate cancer, benign prostatic hypertrophy, and heart disease. The findings in this pilot survey indicate a need among the doctors in the Philippines for education about andropause and the available treatments.     

ON GENDER GAPS AND SELF‐FULFILLING EXPECTATIONS: ALTERNATIVE IMPLICATIONS OF PAID‐FOR TRAINING

This paper presents a model of self‐fulfilling expectations by firms and households which generates multiplicity of equilibria in pay and housework time allocation for ex‐ante identical spouses. Multiplicity arises from statistical discrimination exerted by firms in the provision of paid‐for training to workers, rather than from incentive problems in the labor market. Employers' beliefs about differences in spouses' reactions to housework shocks lead to symmetric (ungendered) and asymmetric (gendered) equilibria. We find that: (1) the ungendered equilibrium tends to prevail as aggregate productivity in the economy increases (regardless of the generosity of family aid policies), (2) the ungendered equilibrium could yield higher welfare under some scenarios, and (3) gender‐neutral job subsidies are more effective that gender‐targeted ones in removing the gendered equilibrium.
