This paper reports the results of a qualitative inquiry into the aetiology of anorexia nervosa in Hong Kong. These results are part of our main research project about family treatment and families with a daughter suffering from anorexia nervosa. This present qualitative study adopts a multiple case study approach (n = 8) and employs a multiple‐source data collection method, involving pre‐ and post‐family treatment interviews, clinical observations of the participants during the treatment sessions and home visits, as well as detailed field notes. The findings indicate that there are biological, psychological, socio‐cultural and familial interpretations of the aetiology of anorexia nervosa. This study challenges the dominant discourse on anorexia nervosa in Hong Kong, which states that the root of the disease lies in a desire for slenderness and beauty, and suggests instead that the aetiology of anorexia nervosa can be discovered only if approached from the systems level. Implications for social work practice are highlighted. 相似文献

In the past four decades, Hong Kong has seen a dramatic transformation of the social location of women in the public sphere,
with deep and far-reaching ramifications for courtship, marriage, fertility, conceptions of parenthood, familial power, and
equality and freedom. A sociology of the family is thus by necessity a sociology of women in particular, and of gender relations
in general. Indeed, recent developments in research on marriage and the family in Hong Kong reflect this new awareness. Using
rigorous sociological frameworks, this new line of research has begun to meet with some success in analyzing contemporary
social issues that are prominent in the public consciousness. This essay reviews studies of four topical areas: determinants
of the postponement of first marriage among women, the effect of live-in foreign domestic workers on family dynamics, violence
against women and children in the family, and the livelihood strategies of cross-border families. These studies have attempted
to integrate the interplay of the impact of a changing economy and society on the family and the role played by women in the
family. The resulting dynamic interactions amongst the members within the family and the changes they bring about become propellants
for change in the economy and society and pose new challenges. The family is indeed a troubled institution. It is so because
myriad public issues are being taken on, confronted, worked through, and acted out within the family. The agony, and indeed
the ecstasy, of the family is a reflection of the success, and failure, of society. 相似文献

The rate of employment for people with spinal cord injuries is relatively low, especially among Asians. To help individuals with spinal cord injuries return to work or retain employment, rehabilitation professionals must understand the barriers to employment and intervene to reduce or remove them. Hence, a focus group study was administered to 16 people with spinal cord injuries to explore return to work barriers. Various ideas, beliefs, responses, and values at different stages of work resettlement were elicited from both employed and unemployed participants, and then summarized. According to the results, several modifications of existing forms of rehabilitation intervention are necessary, as are further research directions. 相似文献

This study aimed to collect evidence on the structural and substantive validity, and test-retest reliability of the Chinese version of the Oswestry Disability Index (CODI). Seventy-nine patients suffering from chronic low back pain were assessed with the CODI. The results of explorative factor analysis primarily suggested a single-factor structure with nine out of 10 items (factor loading = 0.66-0.79). The sex life item was found to load on a different factor. The Cronbach's alpha of all 10 items was 0.81 (p<0.05). When the sex life item was removed from the analysis, the alpha value was increased to 0.89 (p<0.05). The test-retest reliability was estimated based on 56 participants who completed two administrations of CODI in 48 hours. The intraclass correlation coefficient (ICC) computed for the total CODI scores was 0.86 (95% C.I. = 0.81-0.91). The reliability estimated for the item scores using Kappa statistics ranged from a high of k=0.80 for the sitting item to a low of k=0.49 for the traveling item. Kappa statistics were not available for three items. The Chinese version of the Oswestry Disability Index demonstrated satisfactory validity and test-retest reliability, and so could be considered as an appropriate instrument for assessing chronic back pain-related disability in Chinese patients in Hong Kong. Further research should address the cross-cultural and measurement issues in regard to sex life in order to further improve the test content of the instrument. 相似文献

The correlation between social class and official delinquency is one of the more stable findings of sociological research. Consensus, conflict and organizational explanations of this correlation are examined with a coordinated set of survey, interview, and official data gathered in the central area of a middle-sized Canadian city. These data make possible the consideration of behavior and official rate-producing processes in a model that lends support to a combination of conflict and organizational perspectives. Consideration is given to the need for additional research using a similar frame-work in other types of community settings. 相似文献

The problem of discrimination between two stationary ARMA time series models is considered, and in particular AR(p), MA(p), ARMA(1,1) models. The discriminant based on the likelihood ration leads to a quadratic form that is generally too complicated to evaluated explicitly. The discriminant can be expressed approximately as a linear combination of independent chi–squared random varianles each with one degree of freedom, the coefficients, of which are eigenvalues of cumbersome matrices. An analytical solution which gives the coefficients approximately is suggested. 相似文献

We wish to test the null hypothesis if the means of N panels remain the same during the observation period of length T. A quasi-likelihood argument leads to self-normalized statistics whose limit distribution under the null hypothesis is double exponential. The main results are derived assuming that the each panel is based on independent observations and then extended to linear processes. The proofs are based on an approximation of the sum of squared CUSUM processes using the Skorokhod embedding scheme. A simulation study illustrates that our results can be used in case of small and moderate N and T. We apply our results to detect change in the “corruption index”. 相似文献

We propose a simulation-based Bayesian approach to the analysis of long memory stochastic volatility models, stationary and nonstationary. The main tool used to reduce the likelihood function to a tractable form is an approximate state-space representation of the model, A data set of stock market returns is analyzed with the proposed method. The approach taken here allows a quantitative assessment of the empirical evidence in favor of the stationarity, or nonstationarity, of the instantaneous volatility of the data. 相似文献

This is a survey article on known results about analytic solutions and numerical solutions of optimal designs for various regression models for experiments with mixtures. The regression models include polynomial models, models containing homogeneous functions, models containing inverse terms and ratios, log contrast models, models with quantitative variables, and mod els containing the amount of mixture, Optimality criteria considered include D-, A-, E-,φp- and Iλ-Optimalities. Uniform design and uniform optimal design for mixture components, and efficiencies of the {q,2} simplex-controid design are briefly discussed. 相似文献

AbstractRomantic relational aggression is related to numerous mental health consequences but risk and protective factors of perpetrating this type of aggression, historically, have been unclear. This study fills in the research gap by evaluating the impact of parental control, parental care, and peer social support on later perpetration in romantic relational aggression among 84 predominately Chinese college students. Results revealed the positive association between parental control and perpetration in romantic relational aggression, however, this association diminished in the presence of high peer social support (HSS). Despite insignificance in the main effect, parental care was negatively correlated with later perpetration in romantic relationship in the HSS group while a positive association was found in the low peer social support (LSS) group. These highlights provided evidences how parental control and parental care during childhood could be risk factors for later romantic relational aggression as well as how current social support from peer could serve as a protective factor on the negative influence from parent–child relationships. 相似文献
