多级评分聚类诊断法的影响因素

从测验和被试两个层面探讨了属性数目、属性层级关系、被试知识状态分布、属性层级误设和Q矩阵误设等因素对GRCDM的影响, 以进一步考察GRCDM的特性。研究发现：(1)GRCDM对属性数目无依赖, 随属性数目的增多判准率反而增高; (2)被试知识状态分布对GRCDM判准率高低无影响; (3)属性层级误设对GRCDM的影响与属性层级类型有关, 当属性层级为无结构型和发散型时, “属性层级关系错乱”的判准率降幅最大; (4)Q矩阵误设对GRCDM的影响因层级关系而异, 收敛型和发散型受影响较小, 无结构型和线型的判准率在属性既冗余又缺失时降幅最大。     

小学儿童语音意识与汉语拼音能力的关系

探讨了小学一、三、五年级儿童汉语和英语语音意识与汉语拼音水平的关系。结果发现 ,无论是汉语还是英语语音意识都与汉语拼音水平有显著的相关 ;拼音水平高与低组儿童在汉语和英语语音意识上差异显著 ;汉语拼音成绩较高地预测了汉语语音意识的水平 ,而对英语语音意识没有预测力。

The Conceptualization of Processes

There are various sources of the human conceptual system that pertain to causation. According to the realism of René Thom the attention network is attuned to existing patterns of singularities in space/time. According to cognitive linguistics the conceptual system is determined by the neural wiring and the embodied experience of the cognizer. Our concepts do therefore not necessarily reflect objective properties of space and time. In this paper I discuss the two positions and their relation. Following Len Talmy, I present a comparison between how causation is conceived in language and how it is conceived in science. Finally, the notion of agency and its relation to a basic causative sequence is discussed in more detail.     

内蒙古喀喇沁旗农民合作医疗支付意愿与支付能力分析

目的 通过对内蒙古自治区喀喇沁旗三个乡290户农民的调查,分析影响农民支付意愿和支付能力的主要因素。方法 使用相关回归分析。结果 发现农民对合作医疗支付意愿的需求价格弹性系数为-0.68,支付意愿与支付能力相互制约,统计学上有意义的影响因素包括农村居民的收入水平和保险意识。结论 说明农民对合作医疗的需求价格弹性仍属于缺乏弹性类,仍然需要进一步提高农民对合作医疗的支付意愿和支付能力。

Gambling behavior and gambling problems in Norway 2007

In Norway, legalized gambling is pervasive, easily accessible and socially accepted, particularly the participation in national lotteries. We conducted a stratified probability sample study during January–March 2007 (age group 16–74 years, N  = 3,482, response rate 36.1%) to assess gambling behavior and prevalence of problematic gambling by the NORC Diagnostic Screen (NODS). Overall, 67.9% of the study population had been engaged in past-year gambling and 0.7% were past-year problematic gamblers (NODS score 3+). Male gender, low educational level, single marital status, and being born in a non-Western country were variables positively associated with problematic gambling. Past-year problematic gamblers indicated the slot machine (34.6%) and Internet gambling (26.9%) as the most important games, while most non-problematic gamblers pointed out the lotteries (62.3%) as the most important game. The prevalence of self-reported sleeping disorders, depression and other psychological impairments was significantly higher among problematic gamblers. Gambling problems affect people's lives in multiple ways.     

Introduction

Neo-Fregean logicism seeks to base mathematics on abstraction principles. But the acceptable abstraction principles are surrounded by unacceptable (indeed often paradoxical) ones. This is the “bad company problem.” In this introduction I first provide a brief historical overview of the problem. Then I outline the main responses that are currently being debated. In the course of doing so I provide summaries of the contributions to this special issue.     

Perceptions of marital interaction and change during pregnancy: A typological approach

Much of the literature on the transition to parenthood suggests that pregnancy and childbirth arc associated with decreases in marital satisfaction. Recent developments, however, demonstrate that this decrease in couples' satisfaction may be complicated by a number of factors. Among other things, the way couples interact may play a central role in their adjustment to the changes typically associated with pregnancy and childbirth. The purpose of this study was to examine whether couples who espouse varying patterns of interaction also have differing experiences of changes in marital needs and concerns during pregnancy. Couples (N= 190) enrolled in childbirth classes completed a series of questionnaires including Fitzpatrick's Relational Dimensions Instrument and a measure assessing perceived changes in their marital needs and concerns. Results indicated that husbands and wives differed in terms of the amount of nurturance they felt they gave and received, their tendency to worry since pregnancy, and their views concerning their sexual relationship. When changes in needs and concerns were compared across the various couple types, a number of patterns emerged. Wives in Traditional, Separate/Traditional, and Separate/Independent marriages felt they received significantly more nurturance since pregnancy than did wives in Independent marriages. Husbands in Separate/Traditional relationships noted greater increases in worrying than did other husbands. Finally, although couples varied in the frequency of conflict reported, they did not differ with regard to changes in conflict or the influence of such changes on their marriages.
