《现代汉语词典》(第5版)词类标注得失刍议

第5版《现代汉语词典》有两个突出的地方:在区分词与非词的基础上给词标注词类;名词、动词,尤其是形容词下标注附类。同时,文章认为存在以下几个方面问题:属性词的确认;词类失标或标注不当;对某些三音节习用单位的词和非词的处理不一致。     

Interacting mechanisms of time inconsistency

We interact two prominent behavioral mechanisms of time inconsistency that have been used to study inadequate saving: hyperbolic discounting and short-term planning. Hyperbolic discounting is a conventional way to model impulsive decision making, and short planning horizons have been used to represent myopia. One might expect that interacting both mechanisms within the same model would compound the inadequacy of saving. However, our key finding takes the form of a paradox: hyperbolic discounting does not affect consumption and saving allocations if the planning horizon is short and fixed, although it will affect allocations if the planning horizon is equal to the remaining life span. We demonstrate analytically that this finding is robust to the shape of the disposable income path, to the coarseness of the time grid, and to alternative forms of the period utility function.     

Status inconsistency in groups: How discrepancies between instrumental and expressive status result in symptoms of stress

This study examines whether a mismatch between the positions that individuals hold in different status hierarchies results in symptoms of stress. Prior research has focused on inconsistencies between socioeconomic status dimensions (e.g., education and income) and did not find a significant relation between status inconsistency and stress. In this paper, we build on research on role differentiation and propose to study the effect of inconsistencies between instrumental status and expressive status in group contexts. We hypothesize that people with an inconsistency between these status dimensions experience feelings of uncertainty and frustration in their interactions with others and this manifests in stress-related symptoms. We test this hypothesis with data collected in a medium-sized Dutch childcare organization (N = 93). Polynomial regression analysis, visualized in response surface plots, suggests that status inconsistent employees report higher levels of stress.     

货币政策规则的理论发展与启示

货币政策规则(尤其是"泰勒规则")自被提出以来,就深受关注,并在与"相机抉择"的政策决策原则的交锋中不断得到发展。现在的货币政策规则不再局限于货币当局设定固定的货币工具变量的狭隘涵义,而是指货币政策行为的一种指令性的向导,具体包括工具规则与目标规则。经济学家相信,与相机决策相比,规则性的政策能有效减少货币政策的动态不一致性。但是,现阶段在中国建立货币政策规则,尤其是实行通货膨胀目标规则的货币政策的条件并不成熟,而加快金融、财政和计划体制的改革,提高中央银行的独立性,增强政策的透明度,努力提高央行货币政策的一致性的信誉,则是我国的当务之急。     

Prior elicitation in the classification problem

Results are developed concerning the asymptotic behaviour of the Bayes classification rule as the number of unclassified observations grows without bound. It is shown that unclassified observations serve only to estimate the individual population parameters in an unlabeled sense and do not provide information about the labels that are attached to the populations. Prior construction is approached through investigation of prior odds over regions of the joint parameter space (across all populations) deemed likely to contain the true joint parameter vector. It is shown that consideration of these prior odds can lead to more robust a posteriori classification of individual observations.     

Resources,Family Organization,and Domestic Violence Against Married Women in Minya,Egypt

I evaluate the influence of household wealth, women's socioeconomic dependence, status inconsistency, and family organization on physical abuse in the prior year and attitudes about wife abuse and divorce among 2,522 married women in Minya, Egypt. Household wealth is negatively associated with physical abuse. Women who are dependent on marriage because they have sons and less schooling than their husbands are more likely to have experienced physical abuse and to report marginally more tolerance for such abuse. Women who are isolated from natal or biological kin and living with marital relatives are more likely to have experienced physical abuse. Findings underscore the role of women's dependence and social isolation in enabling physical abuse among women of all economic classes.     

组合评价方法的相对有效性分析及应用

Although it is an etfctive method for combination evaluation to solve the inconsistency from dif ferent evaluation conlcusions,different results will still be caused汕en adopting different combination evaluation methods,and this is a new inconsistency.On the basis of introducing the definition of validity and four assumptions,the paper shows an idea comparing different combination evaluation methods.validity through an example,and provides a way to solve the new inconsistency mentioned above.     

The Family Unpredictability Scale: Reliability and Validity

We developed the Family Unpredictability Scale (FUS) to better understand the factors that underlie the presence and consequences of family dysfunction. Familial unpredictability is defined as a lack of consistency in family behaviors and regulatory systems. Family researchers and therapists generated and evaluated items, which were self‐administered by married parents who had children aged 2 to 18 (N= 314 ). Principal‐components analysis yielded four subscales (discipline, nurturance, meals, and money; 22 items total) that were internally consistent; confirmatory factor analysis based on a separate subsample yielded an adequate preliminary representation of this factor structure. The FUS related significantly to known measures of family and individual functioning but not to social desirability. The present study provides preliminary reliability, construct validity, and concurrent validity for this new multidimensional, self‐report assessment of family unpredictability. Research and clinical implications are discussed.     

Cross‐Section Regression with Common Shocks

This paper considers regression models for cross‐section data that exhibit cross‐section dependence due to common shocks, such as macroeconomic shocks. The paper analyzes the properties of least squares (LS) estimators in this context. The results of the paper allow for any form of cross‐section dependence and heterogeneity across population units. The probability limits of the LS estimators are determined, and necessary and sufficient conditions are given for consistency. The asymptotic distributions of the estimators are found to be mixed normal after recentering and scaling. The t, Wald, and F statistics are found to have asymptotic standard normal, χ², and scaled χ² distributions, respectively, under the null hypothesis when the conditions required for consistency of the parameter under test hold. However, the absolute values of t, Wald, and F statistics are found to diverge to infinity under the null hypothesis when these conditions fail. Confidence intervals exhibit similarly dichotomous behavior. Hence, common shocks are found to be innocuous in some circumstances, but quite problematic in others. Models with factor structures for errors and regressors are considered. Using the general results, conditions are determined under which consistency of the LS estimators holds and fails in models with factor structures. The results are extended to cover heterogeneous and functional factor structures in which common factors have different impacts on different population units.
