On Old-Fashioned Versus Modern Homonegativity Distinction: Evidence From Poland

Psychological research on prejudice against homosexuals distinguishes between old-fashioned (traditional) and modern (contemporary) homonegativity, which differ with regard to their content, correlates, and consequences. The current research offers evidence for the validity of old-fashioned versus modern homonegativity distinction in the post-communist, East European context. In Studies 1 and 2 (Ns = 295 and 327, respectively) the Polish adaptations of the non-gendered and gendered Homonegativity Scale (Morrison, Parriag, & Morrison, 1999) and the Modern Homonegativity Scale (Morrison & Morrison, 2003) were developed. Furthermore, divergent (discriminant) validity of traditional and contemporary anti-homosexual prejudice was demonstrated. Old-fashioned and modern homonegativity exhibited differential relationships with social distance and support for same-sex couples’ relational rights.     

Residential mobility and the spatial dispersion of personal networks: Effects on social support

Using a representative national sample of personal networks, this article explores how the spatial dispersion of networks, residential mobility and social support are linked. Three issues will be addressed here. Firstly, how is the spatial dispersion of personal networks related to individuals’ social characteristics, network composition and residential mobility? Secondly, how do the spatial dispersion of networks, residential mobility and their combined effect influence the number and (thirdly) the structure of emotional support ties? Results showed that the extent of the support was affected neither by the geographical distribution of the networks nor by residential mobility. Living far from one's birthplace, however, exerted two distinct, and opposite effects on the support network structure. On the one hand, mobility led to high spatial dispersion of personal contacts, which in turn favored a sparsely knit network centered around the mobile individual. On the other hand, by controlling for the effect of distance between the contacts, we found that individuals that cited long-distance ties tended to be part of more transitive support networks than those that cited local ties. We interpreted the latter effect as evidence that transitive ties may survive greater spatial distances than intransitive ones. These findings are discussed in view of spatial mobility and social network research.     

Buffon's needle and the estimation of migration distances

A procedure is suggested for estimating migration distances from data on the proportion of migrants crossing regional boundaries. The method makes use of Buffon's needle, a problem in geometrical probability from the eighteenth century that was originally used as an empirical means of estimating π. The procedure is described for various scenarios that differ in their assumptions about region shape, the spatial distribution of population, and the distribution of migration distances. An application to migration distances in the United States is given, and additional attention is given to the estimation of intraregional migration distances.

Computation of finite population parameters and approximate probability values for multi-response randomized block permutation procedures (mrbp)

An algorithm is presented for computing the finite population parameters and the approximate probability values associated with a recently-developed class of statistical inference techniques termed multi-response randomized block permutation procedures (MRBP).     

Opportunities of the minimum Anderson–Darling estimator as a variant of the maximum likelihood method

We reveal that the minimum Anderson–Darling (MAD) estimator is a variant of the maximum likelihood method. Furthermore, it is shown that the MAD estimator offers excellent opportunities for parameter estimation if there is no explicit formulation for the distribution model. The computation time for the MAD estimator with approximated cumulative distribution function is much shorter than that of the classical maximum likelihood method with approximated probability density function. Additionally, we research the performance of the MAD estimator for the generalized Pareto distribution and demonstrate a further advantage of the MAD estimator with an issue of seismic hazard analysis.

竹亚科植物过氧化物酶和酯酶同工酶研究

用聚丙烯酰胺凝胶电泳方法分析竹亚科九属二十七种植物过氧化物酶和酯酶同工酶，结果表明：过氧化物酶同工酶谱在种间明显差异，各竹种有特征酶谱。其酶谱特征及酶谱距离可作为竹种分类特征之—，有助于竹种的分类，同时也可了解种间亲缘关系。而酯酶同工酶谱在种间差异小，不宜作竹种的分类特征，但也能反映出种间的亲缘关系。     

中国影子银行违约风险和防范机制研究——来自上市公司委托贷款数据的经验证据

本文运用中国上市公司披露的委托贷款公告数据，实证研究了影子银行的违约风险及其防范机制。数据显示，我国委托贷款的整体违约率为10.09%，远高于同期银行业金融机构的不良贷款率。进一步研究发现，与影子银行风险受信息因素影响的直觉一致，抵押条款和借贷距离会显著影响委托贷款违约率：其一，从抵押视角来看，抵押条款和贷款违约率显著正相关，这表明，为了防范事后的道德风险问题，贷款者会要求借款者提供抵押；其二，从借贷距离视角看，与近距离借贷（或同省借贷）相比，远距离借贷（或异省借贷）的违约风险相对较高，这揭示出，借贷距离越远，贷款者越难对借款者进行甄别和监督，从而推高了借款企业的违约概率。本文研究不仅为我国委托贷款这一影子银行机制的风险状况提供了直接的经验证据，而且对影子银行参与者如何有效防范风险和相关政府部门加强监管具有重要的借鉴意义。
