Family Structure and Children’s Economic Well-Being: Incorporating Same-Sex Cohabiting Mother Families

Research on family structure and child well-being rarely includes children in same-sex parent families, a notable omission since 28 % of female–female couple households contain children. Using the 2010–2013 pooled current population survey (CPS), we examined children’s economic well-being by family structure. These data were ideal for this study because they included a sizeable number of children in same-sex cohabiting mother families and the CPS measured both official and supplemental poverty, incorporating the cohabiting partner. Using the official poverty measure, children in same-sex cohabiting mother families were more likely to be poor than their counterparts in either different-sex cohabiting or married parent families. Using the supplemental poverty measure, children in same-sex mother families were no more likely to be poor than children in all other types of different-sex two-parent families.     

Is There a Link Between Poverty and Food Security?

The study examines cointegration and causal relationship between FDI, terrorism and economic growth in Pakistan using quarterly frequencies for the period 1988–2010. For empirical analysis data is divided into two sub-periods i.e. pre 9/11 (1988–2001) and post 9/11 (2002–2010) periods. The results show that long run cointegration holds between FDI, terrorism and economic growth. Granger causality results indicate that there is bidirectional short and long run causality between economic growth and FDI for both sub-samples. These findings are supported by variance decomposition and impulse response analysis. The findings suggest applicability of modernization theory to explain FDI and economic growth relationship. The results also reveal that terrorism has a deteriorating impact on FDI.     

独立院校医学生人文素质教育分析与对策研究

人文素质教育对于医学生的培养不容忽视。由于我国现行医学生选拔和培养模式、独立院校校园文化薄弱和“三本”学生自身特点等因素影响,独立院校医学生人文素质教育有待加强。独立医学院校应从深化教学改革、提高师资力量、建设校园文化、增强临床教学等四方面入手,努力提高医学生人文素养,不仅有利于医学生的成长成才,也有利于缓和当前的医患矛盾,更有助于推动医疗卫生事业的和谐发展。     

医学生医德教育的困境及对策

医德是保证社会医疗卫生事业健康发展的一个重要因素,而关于医德方面的教育也是医学教育中的重要组成部分之一。可以说,医德教育的好坏直接关系到社会医德风尚,但是从目前的形势上来看,在我国现行的医学生医德教育中实际上是存在着许多问题的,医德教育很多时候都是在困境中前行的。因此在本文中作者在对医德教育其重要意义进行了阐释的基础上就医学生医学教育中存在的诸多问题进行了剖析,并就这些问题提出了相应的解决方案和应对策略,旨在以此为提高医学生医德教育的质量提供一定的参照和指导。     

社会结构变迁与国家治理体系现代化

社会结构是不同社会力量的配置方式。国家治理现代化就是政党、国家、市场、社会不同要素功能的科学定位及其相互关系的均衡状态。考察我国社会结构变迁所经历的传统社会时期、社会主义革命时期、社会主义建设时期、改革开放时期不同阶段,能够发现社会结构变迁与国家治理体系演进逻辑的关系。要推进我国国家治理体系的现代化,必须保证政党、国家、市场、社会不同要素的结构合理化,注重多元主体的力量均衡与制约并构建协商共治体系。     

网络政治参与的实现路径分析

网络政治参与的兴起强烈地冲击和深刻地改变了传统的政治参与方式和政治参与行为,对当代中国政治发展带来了新的机遇和挑战。促进网络政治参与需要着力缩小数字鸿沟,实现网络政治参与的机会平等;构建电子政府,推进公民导向的政务流程再造;增加制度供给,突破制约网络政治参与的瓶颈;培育公民文化,提高公民政治素养,促进有序理性的网络政治参与;加强网络监管,强化政府网络服务功能和网络伦理道德建设。     

并购、吸收能力与企业创新绩效——基于我国医药上市公司数据的实证分析

本文使用2007-2010年我国医药上市公司企业数据,实证分析了企业并购、吸收能力对企业创新的影响。结果表明:在其他条件不变情况下,企业技术寻求型并购与企业创新绩效呈显著正向关系,这表明我国医药上市公司的并购创新效应显著;企业的技术吸收能力对企业并购的创新效应有正向调节作用;企业技术并购对企业R&D强度有显著正向影响;企业所处地区的市场化程度和产权保护水平对并购后企业的R&D强度有正向促进作用;同时企业并购的R&D强度也受到企业的成长性、资产专有性、企业规模等异质性因素的影响。     

社会冲突中的涉民族因素及其解决——兼论法治在民族地区的实现

在我国的社会冲突处置中,由于涉民族因素被赋予了"敏感"、"特殊"等政治属性,事件的衡平与定性往往被抬到政治决策的高度,法治的缺席导致冲突由单纯的法律关系演变成为复杂的政治关系。这种政治优先的冲突治理方式具有效率、秩序的优势,但劣势也非常明显:既不是制度创新,也不是政策替代,非制度化的治理逻辑甚至还抑制了民族地区的社会自我调节功能。在依法治理的角度,当前迫切需要建构统一的国家法治体系,以《民族区域自治法》为依据制定配套性程序规范、完善司法救济、加强规范政府行为的制度建设,以及促进民族地区法治共识的形成等。     

On the computation of the noncentral <Emphasis Type="Italic">F</Emphasis> and noncentral beta distribution

Unfortunately many of the numerous algorithms for computing the comulative distribution function (cdf) and noncentrality parameter of the noncentral F and beta distributions can produce completely incorrect results as demonstrated in the paper by examples. Existing algorithms are scrutinized and those parts that involve numerical difficulties are identified. As a result, a pseudo code is presented in which all the known numerical problems are resolved. This pseudo code can be easily implemented in programming language C or FORTRAN without understanding the complicated mathematical background. Symbolic evaluation of a finite and closed formula is proposed to compute exact cdf values. This approach makes it possible to check quickly and reliably the values returned by professional statistical packages over an extraordinarily wide parameter range without any programming knowledge. This research was motivated by the fact that a very useful table for calculating the size of detectable effects for ANOVA tables contains suspect values in the region of large noncentrality parameter values compared to the values obtained by Patnaik’s 2-moment central-F approximation. The cause is identified and the corrected form of the table for ANOVA purposes is given. The accuracy of the approximations to the noncentral-F distribution is also discussed. The authors wish to thank Mr. Richárd Király for his preliminary work. The authors are grateful to the Editor and Associate Editor of STCO and the unknown reviewers for their helpful suggestions.     

What shapes plant and animal diversity on urban golf courses?

Recent concern over increasing loss of biodiversity has prompted considerable interest in the role of urban green spaces as reservoirs of local biodiversity. This study assessed the diversity of three indicator taxa - plants, ants and birds - on golf courses spanning a wide range of environmental variation in terms of climate, elevation, course age, size and connectivity to native woodland. Species richness and community composition was further compared between contrasting on-course habitat types that reflect different management intensities. We identified a set of taxon-specific environmental correlates indicating an intricate interplay of landscape- and local-scale variables that affect local species diversity. Our results show that floristic diversity is positively associated with the amount of rainfall, whereas ant and bird diversity are related to local-scale factors, particularly the number of trees and the size of water features on a site. The amount of on-course native habitat was a strong predictor of plant and ant diversity and was also associated with the number of unique species at the site level; this reinforces the value of remnant habitat patches as local biodiversity reservoirs that represent mini hot-spots in an otherwise species-poor urban landscape. Community composition for all three taxa differed markedly between non-playing and playing areas, with boundary and remnant habitats generally having more diverse, species-rich communities. Our results suggest that local floral and faunal biodiversity on urban golf courses can be enhanced by creating woody non-playing areas and, especially, by preserving, restoring or expanding remnant habitats.
