Dimensionality of the Chinese Dyadic Adjustment Scale Based on Confirmatory Factor Analyses

Based on the responses of 1,501 Chinese married adults to the Chinese version of the Dyadic Adjustment Scale (C-DAS), confirmatory factor analyses showed that four factors were abstracted from the C-DAS (Dyadic Consensus, Dyadic Cohesion, Dyadic Satisfaction and Affectional Expression) and these four primary factors were subsumed under a second-order Dyadic Adjustment factor. Invariance of the factorial structure between men and women were also found. The findings suggest that the dimensions of marital adjustment assessed by the Dyadic Adjustment Scale [Spanier (1976). Journal of Marriage and the Family, 38, 15–28] can be replicated in the Chinese culture, although some minor refinement might be needed. The present findings also provide support for the use of the C-DAS for assessing marital adjustment in Chinese people.     

Unit training to increase support for military personnel with mental health problems

The present study examined the effectiveness of training designed to increase support toward military personnel with mental health problems. Soldiers from two Battalions (N?=?349) were randomly assigned by squad to receive the training (n?=?179) or to a survey-only control group (n?=?170). Soldiers completed survey assessments at baseline and three months later. Soldiers also completed an implicit association test assessing attitudes toward mental health treatment at the three-month follow-up. Results revealed that soldiers in the training condition reported an increase in supportive behaviours toward soldiers with mental health problems three months following the training, whereas there was no increase in soldiers assigned to the control group. Soldiers in the training condition were also marginally more likely to increase their own treatment seeking in the three months following the training. Discussion focuses on the importance of unit member support for military personnel with mental health problems and the implications for employees in other occupations characterised by the expectation for resilience.     

Revisiting Welfare States. Performance in Reducing Poverty through Longitudinal Multinational Comparison

This article presents the results of a comparative study on the effects of social welfare programs in selected developed countries. Using a fully comparable longitudinal data file from nationally representative household surveys, we estimate the poverty rate and poverty gap before and after social welfare transfers and taxes in order to identify the direct effects of social welfare on poverty. In general, the findings reveal that countries with conservative welfare regimes demonstrate higher poverty performance than do countries with liberal welfare regimes. In particular, the United States lagged behind through all periods under investigation, whereas Germany exhibited the highest performance in poverty reduction.     

Women's Attitudes Toward Family Formation and Life Stage Transitions: A Longitudinal Study in Korea

Although it is well documented that family attitudes become less traditional over cohorts, little is known about how individuals' attitudes change over time. More research also is needed on how the within‐individual changes relate to important life stage events such as marriage, childbirth, and transitions in education and work. Evidence is particularly lacking in Asian countries, which have socioeconomic and cultural contexts very different from those in the West. To fill these gaps in the literature, the authors analyzed the attitudes toward family formation of Korean women in their 20s and 30s (N = 6,042). Individual fixed effects regression using the panel data from the Korean Longitudinal Survey of Women and Families revealed that women became more traditional over time and that transitions to marriage and motherhood partly accounted for the change. These findings are explained within the context of very low fertility in Korea and have implications for other rapidly changing societies.     

Quality of Life in Older Adults: Benefits from Caring Services in Hong Kong

Many older adults are in need of care. Therefore, older people would generally benefit from the use of caring services, notably including home care, residential care, nursing, and medical services. The contributory factors underlying caring services tend to be a caring perspective that aspires to sustain older peoples social relationships and real-life involvement. To gauge the benefits from various social and health services, the present study relies on a large-scale survey of 3000 older adults in Hong Kong, using quality of life as a criterion. Results showed that an older adult who had used (ordinary or enhanced) home care services for a longer time turned out to have appreciably more improvement in quality of life. Besides, those who joined an interest group more frequently were higher in quality of life, including the health domain. On the other hand, frequent use of medical and meal-to-home services were signals that reflected problems detrimental to the older users quality of life. Despite this, the quality of clinics or hospitals, as perceived by the older adult, was the most beneficial. As such, caring services that foster older adults interests, cater to their health care needs, and embody quality can have principal contribution to their users quality of life.     

Simultaneous prediction intervals for multiple comparisons with a standard

k normal populations having common variance are used to construct two-sided and one-sided simultaneous prediction intervals for the differences between the future means of independent random sample from each of these populations compared to a standard. These prediction intervals are particularly useful if one has sampled the performance of several products and wishes to simultaneously predict the differences between future sample mean performance of these products and a standard with a predetermined joint probability. Methods on sample size determination are also given. The procedures are illustrated with a numerical example. Received: February 25, 2000; revised version: February 6, 2001     

佃农理论与南京大学

有关土地使用的合约问题一直是有争议的。以往学者们从传统理论上分析,总是认为租佃制是无效率的。可是他们不能解释为什么类似于租佃制的合约方式在近现代还很有生命力。从南京大学获得的各种土地合约的原始资料可以发现相反的结论,说明租佃制是有效率的。这些合约资料帮助我完成了博士论文,并使得我的论文更加精彩。经济学是解释现象的,我们应该解释那些现实的东西,而不应该只解释并不存在的东西。     

A study of sexual satisfaction and frequency of sex among Hong Kong Chinese couples

There have been several studies in Western societies on the causes and consequences of sexual satisfaction within marriage. Little is known, however about the marital sexual relationship in Chinese societies. Moreover, most published studies used married individuals rather than married couples as participants. The present study examined data from a well-established knowledge, attitude, and practice (KAP) survey of 1,124 Hong Kong Chinese couples on martial sexual relationship. A conceptual model was tested using structural equation modeling (SEM). Interest in sex was found to be the strongest predictor of both sexual satisfaction and frequency of sex for both husbands and wives. Among the sociodemographic variables, the following two were significantly associated with lower frequencies of sex: for wives, that of having a full-time job; and for husbands, the factor of age. Theoretical implications for research on the interplay among culture, marriage, and sex in non-Western societies are discussed.     

The effects of component commonality in an infinite horizon inventory model

This paper studies the effects of component commonality in the context of an infinite horizon inventory model. Three models are proposed that are characterized by different degrees of component commonality. Assuming the three models all follow the same inventory policy, exact service level measures are derived and incorporated into cost optimization problems. With the infinite horizon assumption, potential setup cost reductions can be evaluated due to the inclusion of common components. The results indicate that, as expected, commonality incurs significant cost savings; what is new and unique is that setup cost may increase or decrease when commonality is present. In addition, when the behaviour of the optimal solutions is examined, it is found that some of the well-known properties suggested by the existing one-period models do not hold for this infinite horizon model.     

Long Memory in Foreign-Exchange Rates

Using the Geweke–Porter-Hudak test, we find evidence of long memory in exchange-rate data. This implies that the empirical evidence of unit roots in exchange rates may not be robust to long-memory alternatives. Fractionally integrated autoregressive moving average (ARFIMA) models are estimated by both the time-domain exact maximum likelihood (ML) method and the frequency-domain approximate ML method. Impulse-response functions and forecasts based on these estimated ARFIMA models are evaluated to gain insight into the long-memory characteristics of exchange rates. Some tentative explanations of the long memory found in the exchange rates are discussed.
