Weighted Searching Probability for Classes of Equivalent Search Designs Comparison

Search design is searching and estimating for a few non zero effects in a large set of effects along with estimation of elements in a set of unknown parameters. In presence of noise, the probability of discrimination between the true non zero effect from an alternative one depends on the design and an unknown parameter, say ρ. We develop a new criterion for design comparison which is independent of ρ and for a family density weight function show that it discriminates and ranks the designs precisely. This criterion is invariance to the variable noise which may be present between designs due to noise factors. This allows us to extend the design comparison to classes of equivalent designs.     

用一个ASP页面实现对多个数据库查询

在网站后台数据库查询程序设计中,本文解决了三个关键问题:(1)在表单内插入一个名称为“Send”的隐藏字段,将表单网页和表单处理程序合并为一个ASP程序,从而避免了用户多次查询时在两个页面之间的频繁切换。(2)在函数调用时,通过变换参数的方法实现了对不同数据库的选择查询。(3)利用数组存储技术和循环控制结构,将多种查询结果组织在同一个页面之内,不仅方便了用户浏览,而且减少了网页维护的负担。     

《搜神记》《世说新语》中的选择问句

本文考察《搜神记》《世说新语》中选择问句的格式、形式特征及在句意表达上的特点。通过对两书中这类问句的描写,从一侧面揭示出选择问句在中古汉语前期发展变化的一些情况。     

A hybrid genetic algorithm/mathematical programming approach to the multi-family flowshop scheduling problem with lot streaming

This paper presents a hybrid genetic algorithm/mathematical programming heuristic for the n-job, m-machine flowshop problems with lot streaming. The number of sublots for each job and the size of sublots are directly addressed by the heuristic and setups may be sequence-dependent. A new aspect of the problem, the interleaving of sublots from different jobs in the processing sequence, is developed and addressed. Computational results from 12 randomly generated test sets of 24 problems each are presented.     

博采异同遂混虚实——论干宝的小说理论与实践

自鲁迅《中国小说史略》问世以来,学界咸以为魏晋南北朝小说一如写新闻,并非有意创作。然细阅干宝的生平资料,细阅其《晋纪》、《搜神记序》及《搜神记》却会发现:号曰良史的干宝实爱搜神志怪;在那时就发现小说“难免失实”,划清了与历史散文的界限;其《搜神记》题材采自典籍者多荒诞失实;题材采自现实者实非写实而多虚构。干宝的创作实践了他的小说理论,已开有意为小说之先河,在中国小说史上具有里程碑式的意义。     

社会融合中的性别差异:流动人口工作搜寻时间的实证分析

文章以扩展传统的流动人口社会融合的静态研究视角,使用国家人口计生委2010年上半年流动人口动态监测调查数据,从男女农村流动人口工作搜寻时间的角度进一步比较农村流动人口融入流入地劳动力市场过程的性别差异及影响因素。文章采用持续时间模型,通过研究农村流动人口在流入地城市找工作所花费时间的影响因素,发现虽然在给定时间内,女性流动人口在流入地找到工作所花费的时间比男性要短,但女性找到高收入工作的概率要低于男性,而接受低收入工作的概率要大于男性,从而导致性别区隔的流动人口社会融入模式。     

高校图书馆日文古籍文献价值的开发与利用

高校图书馆拥有很多古旧文献、古籍资料,这些文献如果得到妥善的利用,将有很高的经济价值和研究价值。而这类文献中有部分日文原文资料,大部分都是1945年以前旧日文资料,本文以这些旧日文献资料为例,通过对这些珍贵文献资料的来源、出版地、作者和出版背景、文献类型、文献内容进行挖掘、整理、翻译、解析和研究,使其有价值的东西展现出来,旨在为读者提供系统、完整的外文文献检索,以便更好地服务于高校及社会的广大科研工作者,服务于教学与科研。     

Career Decision State and Assessment of RIASEC Interest Structure

The career decision state (CDS) was studied in relation to RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) profiles in Self-Directed Search results among college students (86 women, 27 men). Three CDS dimensions measured by the Career State Inventory (CSI; certainty, satisfaction, and clarity) were examined as predictors of RIASEC primary and secondary constructs. Significant, albeit modest, zero-order correlations (p < .05) emerged between clarity and 3 secondary constructs (i.e., consistency, commonness, and coherence). Results of regression analyses indicated that CSI dimensions predicted 1 secondary construct (i.e., commonness).     

Marriage,Labor Supply,and Home Production

We develop a search model of marriage where men and women draw utility from private consumption and leisure, and from a non‐market good that is produced in the home using time resources. We condition individual decisions on wages, education, and an index of family attitudes. A match‐specific, stochastic bliss shock induces variation in matching given wages, education, and family values, and triggers renegotiation and divorce. Using BHPS (1991–2008) data, we take as given changes in wages, education, and family values by gender, and study their impact on marriage decisions and intrahousehold resource allocation. The model allows to evaluate how much of the observed gender differences in labor supply results from wages, education, and family attitudes. We find that family attitudes are a strong determinant of comparative advantages in home production of men and women, whereas education complementarities induce assortative mating through preferences.
