无时间性的真无限：黑格尔哲学初期的一个关键问题

1803年前，黑格尔对时间问题缺乏关注。相形之下，在1807年《精神现象学》中，他已将时间看作哲学的重要主题。为什么黑格尔从1795到1802年曾对时间问题无动于衷。在1795年左右，黑格尔主要关注爱的无限性问题。在其法兰克福时期和耶拿初期，他虽然看到了时间性的客观世界的地位，但却并未对此加以强调，而只是强调了主体性的爱与客体性的世界的统一的绝对自身。1802年，通过研究雅各比和康德关于时间问题的争论，黑格尔刻意歪曲了雅各比哲学中的时间问题的重要性，以自己的方式，将时间性的有限存在者问题与物自身问题连接进行考察，从而以一种哲学性的真无限问题策略性地取代了时间问题。这一策略运用与黑格尔原初性的哲学体系理解直接相关，由此，黑格尔将雅各比哲学与康德哲学一并归类为反思性哲学，并对之加以“超越”。     

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).     

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.     

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。     

Small area estimation for longitudinal surveys

Over the last few years many studies have been carried out in Italy to identify reliable small area labour force indicators. Considering the rotated sample design of the Italian Labour Force Survey, the aim of this work is to derive a small area estimator which borrows strength from individual temporal correlation, as well as from related areas. Two small area estimators are derived as extensions of an estimation strategies proposed by Fuller (1990) for partial overlap samples. A simulation study is carried out to evaluate the gain in efficiency provided by our solutions. Results obtained for different levels of autocorrelation between repeated measurements on the same outcome and different population settings show that these estimators are always more reliable than the traditional composite one, and in some circumstances they are extremely advantageous.The present paper is financially supported by Murst-Cofin (2001) Lutilizzo di informazioni di tipo amministrativo nella stima per piccole aree e per sottoinsiemi della popolazione (National Coordinator Prof. Carlo Filippucci).
