Participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors is reviewed. We begin by tracing the origins of and defining both participatory action research and self-help/mutual aid. In so doing, the degree of correspondence between the assumptions/values of participatory action research and those of self-help/mutual aid for psychiatric consumer/survivors is examined. We argue that participatory action research and self-help/mutual aid share four values in common: (a) empowerment, (b) supportive relationships, (c) social change, and (d) learning as an ongoing process. Next, selected examples of participatory action research with psychiatric consumer/survivor-controlled self-help/mutual aid organizations which illustrate these shared values are provided. We conclude with recommendations of how the key values can be promoted in both the methodological and substantive aspects of future participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors.  相似文献

The defensive responses of roseate terns (Sterna dougallii) were studied during the middle of the breeding season when all reproductive stages (incubation, chick-hatching, chick-rearing) were represented, to determine the factors affecting levels of nest defense and whether terns responded differently towards a familiar versus an unfamiliar researcher. Defensive aggression generally varied as a function of researcher identity, time of day, section or location in the colony and nest density. These variables explained from 60 to 66% of the variation in defensive aggression. More terns mobbed one researcher with more dive attacks than the other researcher. Terns were more aggressive in areas where the chicks had just hatched and were most vulnerable. © 1993 Wiley-Liss, Inc.  相似文献

As Hong Kong develops into a knowledge-based economy, there is a strong increase in demand for highly educated and highly skilled workers. At the same time, many other countries are also experiencing shortages of highly-skilled workers as the development of hi-tech and information technology sectors have become an international trend. In this article, we study the changes in demand and supply of highly-skilled workers in Hong Kong and analyse the role that natural population growth, immigration, emigration, and return migration play in relation to the supply of highly-skilled workers. We also give an account of the policy responses of the government of the Hong Kong Special Administrative Region in its attempt to attract highly-skilled professionals as well as the challenges facing Hong Kong in the light of keen international competition.  相似文献

The establishment of counselling and psychotherapy as “evidence‐based” interventions is contingent on the effective implementation of randomised controlled trials (RCTs) in real‐world clinical settings. This paper identifies some of the pitfalls that led to the termination of a practical RCT in a community mental health setting. It reflects upon the significance of the lessons learned by drawing on similar challenges that are documented in the wider literature. Issues surrounding staff turnover, counsellor engagement and procedural clarity are discussed, as is the conflict between the time required for research procedures and counsellors’ clinical time constraints. In our recommendations, we recognise the decisive role of collaboration and counsellor motivation in research partnerships, and the significance of clinical relevance, communication, training and research co‐production in achieving them. Time commitment is identified as the pivotal challenge in the formation and maintenance of collaborative research, but one that also must be overcome for the advancement of the counselling and psychotherapy field.  相似文献

Although MECP2 was initially identified as the causative gene in classic Rett syndrome (RTT), the gene has now been implicated in several phenotypes that extend well beyond the clinically defined disorder. MECP2 mutations have been found in people with various disorders, including neonatal onset encephalopathy, X-linked recessive mental retardation (MRX), classic and atypical RTT, autism, and Angelman syndrome, as well as mildly affected females and normal carrier females. To make matters more complex, in approximately 20% of classic sporadic RTT cases and more than 50% of affected sister pairs, no mutation in MECP2 has been found. X-chromosome inactivation patterns can clearly affect the phenotypic expression in females, while the effect of the type and position of the mutation is more apparent in the broader phenotype than in RTT. Both males and females are at risk, although an excess of paternally derived mutations are found in most cases of classic RTT. Thus, because of the range of disparate phenotypes, the gene may account for a relatively large portion of mental retardation in the population.  相似文献

Information ambiguity is prevalent in organizations and may influence management decisions. This study examines, given imprecise probabilities or outcomes, how managers decide which department's performance to investigate further when they are provided with performance benchmarks expressed in numerical intervals. Seventy‐nine MBA students participated in two experiments involving investigation decisions. We presented participants with interval benchmarks of a firm's expenses. Being below or above the benchmark should have been seen as equally negative. We found that, when facing outcome ambiguity, our participants consistently preferred to investigate further those departments whose performance was described as having an ambiguous outcome (when the outcome's range was centered either below or above the interval benchmark). However, when facing probabilistic ambiguity, there were two predominant choice patterns: consistently choosing to investigate the department whose performance is described with an ambiguous probability, or consistently choosing to investigate the department with unambiguous performance. To gain further insight, we conducted a follow‐up study collecting written protocols of participants' reasons for making choices involving ambiguous performance information. The results show that our participants displayed similar decision‐making processes when facing outcome ambiguity and probabilistic ambiguity. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

An estimate of someone's IQ is a potentially informative personal datum. This study examines the association between external skull measurements and IQ scores, and uses the resulting regression equation to provide an estimate of the IQ of King Robert I of Scotland (Robert Bruce, 1274–1329). Participants were 48 relatively healthy Caucasian men (age 71–76 years) resident in Scotland. Using magnetic resonance imaging data, intracranial volume estimated from external skull length and width correlated greater than .5 (p < .001) with measured intracranial area, which correlates very highly with brain volume. IQ scores estimated from the National Adult Reading Test (NART) correlated .56 (p < .001) with measured intracranial area, and .49 (p < .01) with estimated intracranial volume based on external skull width and length. The partial correlation coefficient of this latter association was .25 (p = .09) after adjustment for measured intracranial area. Thus, actual intracranial area accounts for about 74% of the variance shared by NART and estimated intracranial volume. A cast of the skull of Robert Bruce was measured and its intracranial volume estimated. A regression equation between IQ and estimated intracranial volume, based on data from the 48 subjects, estimated the IQ of Robert Bruce at about 128 (95% confidence interval 106 to  130), i.e. almost two standard deviations above the mean. NART scores show a ceiling effect, so this estimated IQ might be an underestimate. Robert Bruce's estimated high IQ is congruent with his military, political and other intellectual achievements.  相似文献

In two experiments, events that were recorded using continuous duration recording (CDR) were rescored using 10‐s partial interval (PIR), 10‐s momentary time sampling (MTS) and 20‐s MTS. Results of Experiment 1 showed that data paths generated by each interval method produced conclusions about functional control that were similar to those based on CDR when using reversal designs; however, for multielement designs, 10‐s PIR was prone to showing differentiation between data paths that was not evident with CDR. Results of Experiment 2 showed that both 10‐s and 20‐s MTS yielded data paths on behavior–behavior relations (e.g., covarying responses) that were consistent with CDR whereas 10‐s PIR produced some behavior–behavior patterns that were not. In both experiments, 10‐s MTS generated data paths that were nearly identical to the respective CDR data paths. The implications of these findings for researchers and clinicians are briefly discussed. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献
