This paper investigates the modelling and forecasting method for non-stationary time series. Using wavelets, the authors propose a modelling procedure that decomposes the series as the sum of three separate components, namely trend, harmonic and irregular components. The estimates suggested in this paper are all consistent. This method has been used for the modelling of US dollar against DM exchange rate data, and ten steps ahead (2 weeks) forecasting are compared with several other methods. Under the Average Percentage of forecasting Error (APE) criterion, the wavelet approach is the best one. The results suggest that forecasting based on wavelets is a viable alternative to existing methods. 相似文献

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. 相似文献

OBJECTIVE: The authors compared the predictive effects of acculturative stressors and meaning of life on life satisfaction between Chinese students in Australia and in Hong Kong. PARTICIPANTS: In 2006, the researchers recruited 606 Chinese students studying abroad at the University of Melbourne in Australia and at 6 universities in Hong Kong. METHODS: Participants completed a questionnaire that included measures of acculturative stressors, meaning of life, life satisfaction, and demographic information. RESULTS: The Australian sample experienced a significantly higher level of acculturative stressors than did the Hong Kong sample, but life satisfaction did not differ significantly between the 2 samples. Meaning of life had a strong positive contribution and acculturative stressors had a negative contribution in predicting life satisfaction in both samples. Meaning of life partially mediated the relationship between acculturative stressors and life satisfaction in both samples. CONCLUSIONS: The authors discuss the theoretical and practical implications for Chinese students studying abroad. 相似文献

Objective. This study investigates the role of parenting styles and social capital (parental involvement, intergenerational closure, expectation, and trust) in accounting for school performance among ethnic groups and across immigrant generations. Methods. Using data from the Adolescent Health Survey, we estimate fixed‐effects models to analyze students' grade‐point averages. We compare three generations of Asian students and three generations of Hispanic students to the third‐generation (native born with native parents) white students. Results. We find significant differences by both race/ethnicity and generational status in parenting styles and forms of social capital. However, while family socioeconomic status (SES) accounts for the achievement gap between foreign‐born Hispanic and the third‐generation white students, parenting styles and forms of social capital do not moderate any ethnic‐generational differences. Conclusions. Family influences, apart from SES, cannot explain ethnicity‐generation differences in school grades among Hispanic and Asian adolescents. This study provides conceptual clarification and empirical evidence for the significant but independent association between students' school grades and parenting styles on the one hand, and social capital on the other. 相似文献

Background: Depression was translated into Chinese as yiyu,with reference to the yu syndrome in traditional Chinese medicine.Literally meaning not flowing, entangled or clogged,yu, or stagnation in English, is, however, a constructdistinct from depression. Objective: The study aimed to explorethe construct of stagnation through scale development. Method:A concept-driven approach was adopted to generate candidateitems for the Stagnation Scale. Other measures were a validitychecking item, a Beck Depression Inventory (BDI) and a twelve-itemGeneral Health Questionnaire (GHQ-12). Respondents were recruitedby convenience and snowball sampling, resulting in 602 questionnairesbeing completed by adults between the ages of eighteen and sixty-five.Results: Exploratory factor analysis provided a three-factor,sixteen-item solution. The three factors were named Overattachment,Body-Mind Obstruction and Affect-Posture Inhibition. Cronbachsalphas of the entire scale and subscales ranged from 0.82 to0.91. Correlations of the scale total with the validity checkingitem, BDI and GHQ-12 were 0.71, 0.53 and 0.48, respectively.Stagnation showed a pattern of associations with demographicvariables different from depression. Conclusion: The StagnationScale has good psychometric properties, and has meaningful factorstructures. The evidence supports the contention that stagnationis a clinical syndrome distinct from depression. The new concepthas important implications for social work practice. 相似文献

When insurance firms can monitor with non-prohibitive costs the consumption of risk-influencing goods by an insured, they have incentives to tax-subsidize the insured's consumption of the goods. If the government cannot monitor at a lower cost than private insurers, intervention is neither needed nor desirable. Where the government does have a monitoring-cost advantage, it cannot achieve a constrained optimum by commodity tax-subsidies alone. It must also augment the level of insurance and, in some cases, prohibit private tax-subsidies by insurers. Such “invasive” intervention can be avoided if the government regulates the consumption of the risk-influencing goods. 相似文献
