《大乘起信论》铃木大拙译本研究

1900年,铃木大拙以唐代实叉难陀的新译本《大乘起信论》为蓝本,将其从汉语转译成英文。译本将中国佛教大乘思想系统译介给西方,引起学界关注。文化层面上,铃木译本契合了当时的比较宗教学理路以及西方对理性主义进行反思的浪潮。文本策略方面,译文在"自我"与"他者"间达到了一种微妙的平衡,助推了译本的成功。铃木本人方面,译本成功的深层原因要归于其文化自觉——体现为宗教冲动和对东西方文化的体认两方面。     

双向互动发展模式下的“母亲教育”与社区建设

社区建设在近期的主要目标应当是进一步提高居民的自治能力和社区意识，有效整合社区资源以及培养居民互相关怀的传统美德。配合这一目标，社区工作必须摆脱传统工作思路的限制，在工作手段上不断寻求新的突破。母亲教育就是在此背景下提出的，它以科学育人与弘扬传统文化为使命，对促进家庭、邻里和谐，儿童的健康成长以及推动民间力量的发育上都有积极作用。它既拓展了社区工作的实践领域，同时也为社区建设提供了新的思路。     

基于面积直方图及交互信息测度论的医学图像检索方法

颜色直方图是基于内容的医学图像检索(CBMIR)中提取图像特征的一种重要方法,然而其完全丢弃了医学图像颜色的空间分布信息。为了有效地利用图像颜色的空间分布信息,本文提出了一种基于面积直方图及交互信息测度法的医学图像检索方法。该方法进一步分析了具有相同灰度的像素之间在空间分布上的差异,用其在图像中形成的主要连通区域的面积大小代替传统直方图中使用的像素总和,从而能够间接反映色彩的空间分布特征;同时,为了提高检索准确率,本文引进了交互信息测度方法。实验结果表明,本文提出的检索方法能够较为准确的反映医学图像的信息特征,从而提高了检索的鲁棒性、准确性和高效性。     

Entropy properties of record statistics

Record values can be viewed as order statistics from a sample whose size is determined by the values and the order of occurrence of observations. They are closely connected with the occurrence times of a corresponding non-homogenous Poisson process and reliability theory. In this paper, the information properties of record values are presented based on Shannon information. Several upper and lower bounds for the entropy of record values are obtained. It is shown that, the mutual information between record values is distribution free and is computable using the distribution of the record values of the sequence from the uniform distribution.     

A Rational Theory of Mutual Funds' Attention Allocation

The question of whether and how mutual fund managers provide valuable services for their clients motivates one of the largest literatures in finance. One candidate explanation is that funds process information about future asset values and use that information to invest in high‐valued assets. But formal theories are scarce because information choice models with many assets are difficult to solve as well as difficult to test. This paper tackles both problems by developing a new attention allocation model that uses the state of the business cycle to predict information choices, which in turn, predict observable patterns of portfolio investments and returns. The predictions about fund portfolios' covariance with payoff shocks, cross‐fund portfolio and return dispersion, and their excess returns are all supported by the data. These findings offer new evidence that some investment managers have skill and that attention is allocated rationally.     

Generalized additive modelling of sample extremes

Summary.  We describe smooth non-stationary generalized additive modelling for sample extremes, in which spline smoothers are incorporated into models for exceedances over high thresholds. Fitting is by maximum penalized likelihood estimation, with uncertainty assessed by using differences of deviances and bootstrap simulation. The approach is illustrated by using data on extreme winter temperatures in the Swiss Alps, analysis of which shows strong influence of the north Atlantic oscillation. Benefits of the new approach are flexible and appropriate modelling of extremes, more realistic assessment of estimation uncertainty and the accommodation of complex dependence patterns.     

Effects of a Solution-Focused Mutual Aid Group for Hispanic Children of Incarcerated Parents

Children of incarcerated parents are five to six times more likely to go to prison than their peers (Johnston, 1995). Yet, there is a lacuna in the literature that examines the effectiveness of interventions for children with an incarcerated family member. The purpose of the present study is to describe a solution-focused, mutual aid group intervention and to examine the effects of the group on the self-esteem of elementary-age Hispanic children of incarcerated parents when compared to a no-treatment comparison group. Implications for social work practice and research with this vulnerable population are addressed.     

《附释文互注礼部韵略》又音讹误考订

《附释文互注礼部韵略》是最能反映《礼部韵略》原貌的重要资料之一。据我们初步调查,传世的《附释文互注礼部韵略》主要有七种不同的版本,它们都没有经过细致校勘,各有衍误讹夺,尤其是不同版本间若干小韵在反切、又音上的差异,给利用该书研究宋代语音史和宋代韵书史带来了很多不便。我们旨在校正学者们常用的南宋绍定本又音之误,共勘正错讹532处,限于篇幅,仅选取40个颇具代表性的例证,按韵逐条详证。
