Ethnic Integration and Spatial Segregation of the Chinese Population

Because of the overwhelming numerical dominance of the Han within the Chinese population and the highly localised distributions of most minority groups, it is difficult to assess the level of either segregation or ethnic integration in China in a systematic or meaningful manner. Previous studies have either been limited to mapping the locations of minority groups or have been based on provincial data, which for analytical purposes are too coarse to characterise the geographical distribution of minority populations at the sub-provincial level. In this paper, county-level data were used to calculate a diversity index for each county to illustrate the level of ethnic diversity. The results of these analyses indicate that high levels of diversity for a particular province are limited to a specific geographic region within it (especially along the international boundary and in some mountainous areas), rather than characterising the province as a whole. The approach used in this paper also employs a new measure based upon the idea of a standard deviational ellipse—a measure that is used to evaluate the level of spatial segregation between ethnic groups. An index illustrating the degree of spatial correlation between ethnic groups was derived for each province using county-level data. The results indicate that, although major population groups in southern and western China display a low level of spatial correlation (i.e. they are highly segregated), these same areas nevertheless exhibit relatively high levels of ethnic diversity.     

Do terrorist attacks affect ethnic discrimination in the labour market? Evidence from two randomized field experiments

Terrorist attacks are known to influence public opinion. But do they also change behaviour? We address this question by comparing the results of two identical randomized field experiments on ethnic discrimination in hiring that we conducted in Oslo. The first experiment was conducted before the 2011 terrorist attacks in Norway; the second experiment was conducted after the attacks. In both experiments, applicants with a typical Pakistani name were significantly less likely to get a job interview compared to those with a typical Norwegian name. But the ethnic gap in call‐back rates were very similar in the two experiments. Thus, Pakistanis in Norway still experienced the same level of discrimination, despite claims that Norwegians have become more positive about migrants after the far‐right, anti‐migrant terrorist attacks of 2011.     

Exposure to interpersonal racism and avoidance behaviours reported by Aboriginal and Torres Strait Islander people with a disability

Using the National Aboriginal and Torres Strait Islander Social Survey, this paper examines exposure to interpersonal racism and avoidance reported by Aboriginal and Torres Strait Islander people with disabilities. We find that in 2014–2015, 32 per cent of people aged 15–64 without a disability experienced racism compared with 42 per cent of those with a disability. Half of those living with an intellectual or psychological disability reported racism, and about 20 per cent of those with any disability avoided settings such as healthcare, education or the general public due to past instances of racism, relative to 11 per cent of those without a disability. After adjusting for confounding factors and complex survey design, presence of a disability was associated with a 1.6–1.8 odds increase in exposure to racism, more frequent racist exposure and avoidance. Disability was further associated with an approximate doubling of the odds of reporting multi-context avoidance and the likelihood of reporting both racism and avoidance in tandem. Severity of disability, higher numbers of disabling conditions and specific disability types were associated with increased odds of racism and avoidance. Independent of these effects, removal from one's natural family and identifying with homelands was strongly associated with racism and avoidance.     

A Qualitative Study of Parents’ and Children’s Views on Mediation

This qualitative study examined the benefits to children of family mediation for divorcing couples and the limitations of such mediation. To capture the perspectives of parents and their children, we invited 40 parents and 10 children to participate in the study. The parent informants reported that mediation improved the efficacy of their parenting and alleviated their children’s stress about their divorce. In contrast, the child informants felt they were powerless when involved in the mediation process and that they received limited support from the mediators. Strategies are proposed for improving the cultural applicability of mediation services for children in a Chinese society.

Elder mistreatment predicts later physical and psychological health: Results from a national longitudinal study

Stress process theory predicts that elder mistreatment leads to declines in health, and that social support buffers its ill effects. We test this theory using nationally representative, longitudinal data from 2,261 older adults in the National Social Life Health and Aging Project. We regress psychological and physical health in 2010/2011 on verbal and financial mistreatment experience in 2005/2006 and find that the mistreated have more anxiety symptoms, greater feelings of loneliness, and worse physical and functional health 5 years later than those who did not report mistreatment. In particular, we show a novel association between financial mistreatment and functional health. Contrary to the stress buffering hypothesis, we find little evidence that social support moderates the relationship between mistreatment and health. Our findings point to the lasting impact of mistreatment on health but show little evidence of a buffering role of social support in this process.     

Piecewise Cox models with right-censored data

We study a general class of piecewise Cox models. We discuss the computation of the semi-parametric maximum likelihood estimates (SMLE) of the parameters, with right-censored data, and a simplified algorithm for the maximum partial likelihood estimates (MPLE). Our simulation study suggests that the relative efficiency of the PMLE of the parameter to the SMLE ranges from 96% to 99.9%, but the relative efficiency of the existing estimators of the baseline survival function to the SMLE ranges from 3% to 24%. Thus, the SMLE is much better than the existing estimators.     

Use of the International Prostate Symptom Score (IPSS) in Chinese male patients with benign prostatic hyperplasia

Purpose: To test the psychometric properties of the International Prostate Symptom Score (Hong Kong Chinese version 2) (IPSS) in Chinese male patients with benign prostatic hyperplasia (BPH) under secondary care.

Methods: A prospective longitudinal study was done by interviewing subjects at baseline, at 2 week after baseline for assessing test–retest reliability and at 26 week after baseline for assessing responsiveness. All subjects were interviewed to complete a structured questionnaire including IPSS, Short Form-12 Health Survey version 2 (SF-12v2) and Depression Anxiety Stress Scale (DASS).

Results: The IPSS HRQOL score had weak correlations with SF-12v2 summary and DASS domain scores. For reliability analysis, Cronbach’s alpha coefficient was 0.90 for the seven symptom-related items. The intraclass correlation coefficients of the IPSS total symptom score and HRQOL score were 0.90 and 0.86, respectively. For sensitivity, statistically significant differences were detected between the subjects with BPH and those without for IPSS total symptom score (effect size?=?0.68) but not the IPSS HRQOL score. The areas under ROC curves for the IPSS total symptom and HRQOL scores were 0.67 and 0.60, respectively.

Conclusions: The IPSS was valid, reliable instrument in Chinese patients with BPH. The IPSS total symptom score, but not the HRQOL score, is sensitive in differentiating subgroups.     

Perceived social support in Chinese parents of children with attention deficit hyperactivity disorder in a Chinese context: Implications for social work practice

This article reports the results of a Hong Kong study (no. of parents = 121) which identified perceived social support (PSS), both overall and four types of support, of Chinese parents of children with attention deficit hyperactivity disorder (ADHD) and examined the impact of PSS on the interrelationship between the ADHD symptoms and parenting stress. The parents perceived support of their primary social network as more satisfactory than professionals’. Parenting stress of the high PSS group was lower than the low PSS group’s. The PSS-overall, parenting role, and the ADHD symptoms explained a significant variance of parenting stress. The results pave the way to develop a complex social work model in helping.     

Validation of the Chinese Version of the Gamblers’ Belief Questionnaire (GBQ-C)

A growing body of evidence is documenting the significant role of cognitive factors in influencing gambling behaviors. Although measures of cognitive biases have been developed, further validation of these scales is needed among non-Western samples. The 21-item Gamblers’ Belief Questionnaire was originally developed and validated by Steenbergh et al. (in Psychol. Addict. Behav., 16: 143–149, 2002). The scale then has been widely used in the gambling research of the West. The present study was designed to examine and validate the Chinese version of Gamblers’ Belief Questionnaire (GBQ-C) using 258 Chinese participants. Confirmatory factor analyses indicated the 2-factor model provided a good fit to the data as evidenced by various model fit indices (CFI?=?.91, RMSEA?=?.08 and SRMR?=?.05). Additional evidence for the validity of the GBQ-C was provided by significant correlations with other relevant measures (range .40–.75). In sum, the present study provides support for the GBQ-C as a valuable tool for assessing gambling cognitions among Chinese samples.
