Effects of Marriage and Children on Financial Risk Tolerance: A Synthesis of Family Development and Prospect Theory

Family development and prospect theory were used as a framework to predict variability in individuals' subjective financial risk tolerance within distinct family structures. Gender, age, and income were expected to interact with the main effects of family structure (marital status and children). Theory-generated hypotheses were examined in Study 1 (data from university housing respondents, n = 76) and Study 2 (the 1998 Survey of Consumer Finances, n = 4,305). One family structure main effect (child presence) was significant for investment risk tolerance in both studies. Family structure interactions (marital status × age and child × income) were significant for employment risk (Study 1), and child × age was significant for investment risk in Study 2.     

Assessing goodness-of-fit of categorical regression models based on case-control data

Demonstrated equivalence between a categorical regression model based on case‐control data and an I‐sample semiparametric selection bias model leads to a new goodness‐of‐fit test. The proposed test statistic is an extension of an existing Kolmogorov–Smirnov‐type statistic and is the weighted average of the absolute differences between two estimated distribution functions in each response category. The paper establishes an optimal property for the maximum semiparametric likelihood estimator of the parameters in the I‐sample semiparametric selection bias model. It also presents a bootstrap procedure, some simulation results and an analysis of two real datasets.     

网上购物风险来源、类型及其影响因素研究

从风险来源的角度深入地研究了网上购物感知风险类型与其相对强度,对于企业从风险来源上降低和管理网上风险具有重要的指导意义.文章发现消费者在网上购物时,风险主要来源于产品本身、远距离交易、互联网这种交易模式和网站这四个方面.研究结果揭示了,当消费者在网上购物的时候,所感受到最强烈的三个风险分别是,来自于产品本身的产品绩效风险、来自于远距离交易的服务风险和来自于网站的来源风险.最后,研究还发现,消费者网上购物感知风险的强弱与消费者的年龄、网络购物频率之间存在较强的相关性,年龄越大,感知风险越强;网上购物频率越高,感知风险越低.     

风险社会的来临与历史决定论的消解

风险社会的来临改变了人类的生存境遇和生活体验，也必将导致人们观念和行为方式的改变。对现代风险社会进行认真的反思，并将与“人为的不确定性”相联系的风险概念引入，可以消解历史决定论的思维定势，也可以为马克思历史唯物主义的真实意蕴及当代性的彰显提供全新的解释维度和现实根据。     

The potential of integrated modelling in conservation biology: A case study of the black‐footed albatross (Phoebastria nigripes)

Conservation biology aims at assessing the status of a population, based on information which is often incomplete. Integrated population modelling based on state‐space models appears to be a powerful and relevant way of combining into a single likelihood several types of information such as capture‐recapture data and population surveys. In this paper, the authors describe the principles of integrated population modelling and they evaluate its performance for conservation biology based on a case study, that of the black‐footed albatross, a northern Pacific albatross species suspected to be impacted by longline fishing     

语调变体解构

正确把握语调变体是言语交际成败的关键;口语中不同语调的使用表述了说话人不同的思想感情和态度.也正是这种语用语调的变异导致了语义理解和思想表达的细微差别,差之毫厘,谬以千里.本文从语调功能,常规语调运用及语调变体三个角度,以翔实的例句分析,对英语语调变体进行解构.     

供应链风险产生根源的理论分析

根据现有文献研究成果,结合实际调研分析,将供应链风险因素整理归纳为系统风险、供应风险、物流风险、信息风险、财务风险、管理风险、需求风险和环境风险。每种风险因素并非独立存在,而是相互影响、互为根源。其非线性叠加结果将会放大供应链整体风险水平。因此,必须认识到其存在的风险,只有在明确各种风险产生根源的基础上,才能恰当地制定、选择和采取有效措施,规避风险,确保供应链整体绩效稳步提高。     

荣辱观教育的实现方法

进行荣辱观教育是社会主义道德建设的重要任务。荣辱观教育需要坚持正确的荣辱衡量标准，明确义利的辩证统一关系；坚持道德价值的一元与多元的有机结合；坚持原则性与灵活性的结合，使荣辱观教育既具有内在的逻辑性和层次性，又具有现实针对性和可操作性。     

安置方式、人际交往与移民适应:江苏、浙江343户三峡农村移民的比较研究

本文依据对江苏、浙江两省6个县343户三峡外迁农村移民的调查数据，分析了相对集中与完全分散这两种不同的安置方式，以及由此所形成的两种不同的人际交往状况对外迁移民社会适应的影响。研究发现，从总体上看，移民在安置地的人际交往状况对移民的社会适应的影响十分显著。无论是移民之间的交往、还是移民与当地居民之间的交往，都会大大增强移民融入当地社会的程度。     

浅析高校普通话水平测试工作的科学化管理

高校普通话水平测试（PSC）工作的科学化管理能够保证测试质量、完成高水平测试工作，同时可以营造良好的学校语言文字氛围和推广及普及普通话。针对目前高校在PSC管理方面存在的问题，本文提出了制定健全的管理制度、实现普通话测试管理的科学化与信息化、积极探索现代化的普通话测试手段、加强对普通话测试员队伍的综合管理以及普通话测试的检查督导工作等措施。通过这几方面的措施确保PSC工作走向制度化、规范化、科学化。
