性观念:70后和80后的比较——基于CGSS2005数据的分析

当前中国社会有关70后和80后之间的各种争论层出不穷,主要集中在性观念等道德观的层面,例如,许多人认为80后在性观念上面比70后更为开放,但是缺乏严谨的数据论证。因此,本文使用CGSS(中国综合社会调查)2005年的数据对此进行了分析,发现70后、80后这种基于年龄的代际概念并没有统计上的意义,即在控制相关变量后,这两个年龄阶段群体的性观念开放程度并不存在显著的差异。     

Predicting Future Commitment to Care for Frail Parents Among Employed Caregivers

A study of 133 full time employees with parent care responsibilities investigated various factors that could reduce this group's future caregiving commitment to aging parents. Study factors included: caregiver attributes, level of caregiving involvement, job stress, tensions between the caregiver and the dependent parent, caregiver's level of physical and mental strain, and limited support from family and friends. The relationship between the caregiver and the parent was the best predictor of sustained commitment to caregiving. One aspect of the employees' work experience made a small, but important contribution to respondents' future care plans. Those employees who frequently adjusted their work schedule and routine to accommodate parent care demands were less likely to sustain their caregiving commitment. Reasons for these findings are explored and implications for social policy and clinical practice are discussed.     

人性与自由情感——兼论奥斯卡影像美学

人类存在着两类不同性质的情感：自由情感和必然情感。所谓自由情感指的是刺激源和这种情感对象之间没有任何直接的利害关系条件下所产生的情感。美的本质就在于自由情感。奥斯卡艺术堪称电影艺术中的经典。奥斯卡奖近百年的评奖历史证明人性是社会大众和奥斯卡奖评委共同的最好的审美趣味激发源。其中爱情、亲情、友情是奥斯卡影像中最浓墨重彩的人性主题，是自由情感的主要源泉，也是奥斯卡影像美学的核心。     

Exponentiality test based on Renyi distance between equilibrium distributions

ABSTRACT

On the basis of Csiszar's φ-divergence discrimination information, we propose a measure of discrepancy between equilibriums associated with two distributions. Proving that a distribution can be characterized by associated equilibrium distribution, a Renyi distance of the equilibrium distributions is constructed that made us to propose an EDF-based goodness-of-fit test for exponential distribution. For comparing the performance of the proposed test, some well-known EDF-based tests and some entropy-based tests are considered. Based on the simulation results, the proposed test has better powers than those of competing entropy-based tests for the alternatives with decreasing hazard rate function. The use of the proposed test is evaluated in an illustrative example.

The Making of COBRS 2.0

Abstract

Recently introduced advances in microcomputer technology offer opportunities for improving child welfare agencies' access to powerful case assessment and program evaluation tools. This paper discusses the process of fitting a child behavior outcome measurement system to a menu driven microcomputer program. Traditional strategies for measuring outcome effectiveness, managerial priorities and operational constraints are examined in terms of their bearing on the introduction of new microcomputer technology. The developmental process is traced to show how these factors influenced the addition of a number of user options to the basic program to enhance its adaptability to specific agency needs. Initial user feedback indicated general satisfaction with the basic program and the applicability of its output, little or no experimentation, as yet, in adapting the system, and, a minor need to adjust the sequencing of operator activities to better fit the realities of agency work rhythms.     

Locally best invariant test for outliers in a gamma type distribution

It is shown that the locally best invariant test for the existence of outliers for scale parameters of the gamma distribution is given by Bartholomew's test for exponentiality which is the ratio of the sum of squares of the data to the square of the sample mean. The optimality robustness, including null and nonnull robustness of the test is shown. A small simulation study to compare the power among the other eight competitive tests for testing exponentiality is performed. It is seen that the locally best invariant test is not always best but is reasonably good. It is slightly better than Cochran's test and suffers less from the limiting masking effect.

Calculation of the expected lifetime lost due to an extra risk

Methods are given for estimating the average years of life lost when a person is discovered to be at risk from an extra hazard. The methods use the probability per year of the extra risk striking, and the mean and standard deviation of lifetime in the absence of the risk. The formulae are simple enough that only a hand‐held calculator is needed.
