Associated factors of post-stroke depression among Hong Kong Chinese: a longitudinal study

The aim of this study was to explore associated factors of post-stroke depression (PSD) among Chinese first-time stroke patients. A 6-month prospective design was adopted with data collected by face-to-face interviews and physical assessment at two observation time points: T1, within 48 h of admission to the rehabilitation hospitals and T2, 6 months after the first interview in the subject's current place of residence. The prevalence of PSD at T1 and T2 was found to be 69% and 48% respectively. Backward linear regression showed that five variables explained 55% of the variance of PSD at T2. Participants who had a higher level of depression at T2 tended to have a higher level of functional disability, less social companionship and poorer informational support. Those who had been homemaker at pre-morbid state and those who exhibited a higher level of depressive symptoms at T1 showed a higher level of depression at T2. The results of this study suggest that PSD could be a psychological condition arising from the disabling consequences and altered family roles caused by a stroke.     

Effects of rater goals on rating patterns: evidence from an experimental field study

The goal-based perspective of performance appraisals suggests that raters who pursue different goals give different performance ratings. Yet previous studies have not provided strong empirical evidence that there are different impacts of different goals on mean rating and discriminability, nor have they provided evidence of a goal-rating causality. The authors extend the literature by manipulating rater goals in the context of peer evaluations of graded group projects with a sample of 104 undergraduate students. They find that (a) pursuing a harmony goal increased mean rating and decreased discriminability, and (b) pursuing a fairness goal increased mean rating and decreased discriminability when the group projects had not ended and increased mean rating but did not change discriminability when the group projects had ended.     

Role of resilient personality on lower achieving first grade students' current and future achievement

This study investigated a measurement model of personality resilience and the contribution of personality resilience to lower achieving first grade students' academic achievement. Participants were 445 ethnically diverse children who at entrance to first grade scored below their school district median on a test of literacy. Participants were administered an individual achievement test in first grade and 1 year later. Confirmatory factor analysis confirmed a second-order latent construct of resilient personality defined by teacher-rated conscientiousness, agreeableness, and ego-resiliency that was distinct from measures of externalizing behaviors and IQ. Using latent structural equation modeling and controlling for baseline economic adversity, IQ, and externalizing symptoms, resilient personality predicted children's concurrent and future achievement (controlling also for baseline achievement in the prospective analyses). Model fit was invariant across gender.     

Response latency of gerbils and hamsters to nuts flavoured with bitter-tasting substances

The unconditioned reactions of Mongolian gerbils to peanuts rolled in sucrose octa-acetate (SOA) or denatomium benzoate (Bitrex) were studied in Experiment 1. Although SOA evokes as high a bitterness rating among humans as quinine salts, the gerbils' latency to ingest a nut flavoured with the former was similar to that to an unflavoured nut. Their oral latency to a nut that was flavoured with Bitrex was longer than to either an unflavoured one or one flavoured with SOA. However, the fact that they ingested a nut flavoured with the “most bitter substance known to man” within 70 sec after contact is surprising. Experiment 2 dealt with the effects of a peanut that was either unflavoured or flavoured with SOA or quinine and then paired with a LiCl injection. The oral latency of these gerbils to a nut conveying such flavours was assessed for six days after this conditioning. A nut flavoured with quinine acquired aversive properties but not ones that were flavoured with SOA or were unflavoured. Similar results were observed in Experiment 3, when hamsters were tested under comparable conditions. The theoretical implications of these results are discussed.     

Social Cynicism and Job Satisfaction: A Longitudinal Analysis

Social cynicism, a negative view about people and social institutions, was found to show a negative correlation with job satisfaction across societies. A preliminary study in Hong Kong showed that social cynicism and job satisfaction correlated negatively across individuals as well. To confirm the causal effect of social cynicism on job satisfaction, a longitudinal study in Shanghai, China, with three waves of surveys, was conducted. Results showed that social cynicism correlated negatively with job satisfaction measured concurrently, and was predictive of job satisfaction measured subsequently. Consistent with the buffering hypothesis, perceived well‐being was a significant moderator in that the negative relationship between social cynicism and job satisfaction was significant only when perceived well‐being was low. On s'est aperçu que le cynisme social (une vision négative des gens et des institutions sociales) entretenait une corrélation négative avec la satisfaction professionnelle quelle que soit la société. Une étude préliminaire à Hong‐Kong a montré que le cynisme social et la satisfaction professionnelle présentaient également une corrélation négative au niveau de l'individu. Dans le but de confirmer le statut causal du cynisme social sur la satisfaction professionnelle, on a mené une étude longitudinale en Chine, à Shanghai, avec trois enquêtes successives. Les résultats montrent que le cynisme social est négativement reliéà la satisfaction professionnelle mesurée au même moment et prédit la satisfaction professionnelle mesurée ultérieurement. En accord avec l'hypothèse portant sur la résistance aux aléas de l'existence, le bien‐être perçu est un modérateur actif dans la mesure où la relation négative entre le cynisme social et la satisfaction professionnelle n'est significative que lorsque le bien‐être perçu est médiocre.     

Attentional cueing by cross-modal congruency produces both facilitation and inhibition on short-term visual recognition

The attentional modulation of performance in a memory task, comparable to the one obtained in a perceptual task, is at the focus of contemporary research. We hypothesized that a biphasic effect (namely, facilitation followed by inhibition) can be obtained in visual working memory when attention is cued towards one item of the memorandum and participants must recognize a delayed probe as being identical to any item of the memorandum. In every trial, a delayed spiky/curvy probe appeared centrally, to be matched with the same-category shape maintained in visual working memory which could be either physically identical (positive trials) or only categorically similar (negative trials). To orient the participant's attention towards a selected portion of a two-item memorandum, a (tzk/wow) sound was played simultaneously with two lateral visual shapes (one spiky and one curved). Our results indicate that an exogenous attentional shift during perception of the memorandum, induced by a congruent audio–visual pairing, first facilitates and then inhibits the recognition of a cued item (but not of a non-cued item) stored in visual working memory. A coherent pattern of individual differences emerged, indicating that the amount of early facilitation in congruent-sound trials was negatively correlated with recognition sensitivity in no-sound trials (suggesting that the inverse effectiveness rule may also apply to memory) and positively correlated with later inhibition, as well as with the self-reported susceptibility to memory failures.     

Integrative Family and Systems Treatment with Parental Mental Illness: A Hong Kong Chinese Family

Integrative Family and Systems Treatment (I-FAST) is a systems-based, home-based, and strengths-oriented treatment model that has been developed and implemented within the community mental health system. Using a single case example, this paper discusses the application of I-FAST to a Chinese family in Hong Kong in which the mother was diagnosed with depression. The paper critically examines the deficit-based approach, widely used in the mental health field, which stigmatizes people with psychiatric disabilities. Treatment implications of families with parental mental illness in a Chinese context are discussed.     

替罗非班不同给药途径对DM合并急性STEMI患者PCI术后血小板α-颗粒膜蛋白及心肌灌注水平的影响

为探讨替罗非班不同给药途径对糖尿病（DM）合并急性ST段抬高型心肌梗死（STEMI）患者PCI术后血小板α-颗粒膜蛋白及心肌灌注水平的影响,对149例DM合并急性STEMI患者进行研究,测定并比较经静脉（A组）、冠脉给药途径（B组）和无替罗非班（C组）的患者术前及术中应用替罗非班后血小板α-颗粒膜蛋白GMP140浓度、造影结果、心肌酶及肌钙蛋白I水平峰值及峰值时间、心电图变化。结果显示A、B两组术中血小板α-颗粒膜蛋白浓度较术前明显降低（P〈0．05）,且B组较A组降低更明显（P〈0．05）,而C组未见明显变化（P〉0．05）,A、B两组术后即刻TIMI血流、2h sumSTR、心肌酶及肌钙蛋白Ⅰ峰值及峰值时间的变化均优于C组（P〈0．05）,且B组优于A组（P〈0．05）。因此,替罗非班可以降低血小板α-颗粒膜蛋白浓度和改善心肌灌注水平,与静脉途径给药相比,经冠脉给药更具有优势。
