Housing First and Photovoice: Transforming Lives,Communities, and Systems

This article presents findings from a community‐based participatory evaluation of a Housing First program on the Island of O'ahu. In this study, clients in a Housing First program used Photovoice to evaluate the program and to advocate for progressive housing policies. Written together by members of the Housing First Photovoice group, this collaborative article describes the outcomes from both the Housing First program and the Photovoice project and demonstrates the ways in which participatory program evaluations can interact with client‐driven programs like Housing First to produce a cumulative, transformative impact. Findings suggest that community psychologists hoping to re‐engage with community mental health systems through enacting transformative change should consider taking a community‐based participatory approach to program evaluation because increased client voice in community mental health programs and their evaluations can have far‐reaching, transformative impacts for research, practice, and policy.     

网络道德建设:从虚拟走向现实

《新时代公民道德建设实施纲要》将网络道德建设作为新时代公民道德建设的重要内容,这是对互联网迈入新时代的自觉意识,对新时代网络空间属性、网络行为属性和网络道德属性深刻把握的反映。一"在因特网上没人知道你是一条狗"(简称"狗论I"),《纽约客》(1993年)的一幅漫画以一种耐人寻味的方式向人们展现了网络空间的虚拟性,网络作为虚拟空间似乎外在于现实空间。     

An expert–novice comparison of feature choice

Perceptual experts have learned to rapidly and accurately perceive the structural regularities that define categories and identities within a domain. They extract important features and their relations more efficiently than novices. We used fingerprint examination to investigate expert–novice differences in feature choice. On each fingerprint within our set, experts and novices selected one feature they thought was most useful for distinguishing a particular print and one feature they thought was least useful. We found that experts and novices often differed in the features they chose, and experts tended to agree more with each other. However, any such expert–novice difference appeared to depend on the image at hand typically emerging when salient or more conspicuous features of a fingerprint were unclear. We suggest that perceptual training ought to direct attention to useful features with the understanding that what is useful may change depending on the clarity of the stimuli.     

Cognitive performance,monetary incentive,and aggression

Individuals with impaired cognitive abilities associated with frontal lobe function have recently been shown to manifest increased aggression. This study investigated the effect of contingent money to inhibit aggression in these individuals. One hundred and forty males, aged 18–40, were ranked according to their performance on the Spatial Conditional Associative-Learning task. Forty-eight males (24 with scores in each of the upper and lower performance quartiles) participated in the full study. Half of the subjects competed in a Taylor aggression task where they received a monetary incentive for choosing lower shocks; the remainder competed without any monetary contingency. Aggression was defined as shock intensity delivered to a sham opponent. Shock intensity significantly increased as a main effect of lower cognitive performance, absence of monetary incentive, and provocation. In addition, provocation interacted significantly with test performance. Finally, individuals in the upper cognitive performance quartile showed significantly greater reductions of unprovoked aggression in response to monetary incentive. The results are discussed in terms of impairments in the ability to associate inhibitory influences in the formulation of behavioral strategies under aggressive conditions. © 1996 Wiley-Liss, Inc.     

Expectations and beyond: The nexus of AI instrumentality and brand credibility in voice assistant retention using extended expectation-confirmation model

AI-based voice assistants (AIVA) are capable of interpreting human speech and responding with useful information, aiding with tasks, and controlling other devices. The usage of these AIVAs has grown significantly worldwide. Despite this growth, studies on user behavior related to continued usage intention of AIVAs and effects on the long-term commercial sustainability of brands, remain low. What is less understood is the potential of AI instrumentality attributes and brand credibility components in provoking shifts in post-use behavior of AIVAs. This study proposes a model which expands on the Expectation-Confirmation Model for user continuance behavior of AIVAs, by integrating user's technology related traits, AI instrumentality attributes and brand credibility. To verify the research hypotheses, the study employed partial least square—structural equation modelling, based on 281 validated responses of a survey. This study highlights the significance of Optimism, Innovativeness, and Discomfort for post-adoption confirmation. Higher post-adoption confirmation is strongly associated with perceived intelligence, anthropomorphism, information quality, and system quality. Anthropomorphism and information quality are key factors for brand expertise, while anthropomorphism and system quality are significant for brand trustworthiness. The study confirms that brand expertise and trustworthiness lead to post-use satisfaction and use continuance intention. Understanding the antecedents of satisfaction and continuance intention extends the existing literature on AIVAs and provides valuable insights for academics and practitioners alike. Some implications for researchers and managers are discussed.     

新加坡华人在M.M.P.I的反应模式

本研究的结果显示中译及英文MMPI在新加坡使用时不但具颇高之信度,且两者可视作相等之版本。有关资料亦表明受中文教育和受英文教育的新加坡华人在MMPI上有不同的反应倾向。前者之剖析图属2.8类型,其选答模式与香港地区者相似。后者之剖析图则属8.9类型,其选答模式与美国者较为接近。 在比较中国与新加坡华人在量表的顺序排列时,发现后者在Ma量表之T分数占较高的等级,在Pa量表则占较低的等级。与香港地区比较时,则新加坡华人在Si量表之等级较高。有关量表顺序排列之等级相关則表明了受中文教育的新加坡华人与中国和香港地区之MMPI剖析图,有显著的相似性。但受英文教育的新加坡华人则仅男性之剖析图与香港地区者相似。进一步证实了受不同语文教育的新加坡华人在性格上有差异。 本研究收集的资料,不但可供解说测验之参考,亦可作为进一步效度研究的基础。在跨文化的研究上更提供了有用的资料。     

The diagnostic process,the diagnosis and homeostasis

In this paper I shall try to analyse appropriate logic and actual methods as a preliminary to developing expert systems that will simulate clinical diagnosis. It is doubtful that all diagnoses address the same kind of problem and hence no one logic will suffice. Sometimes the signs and symptoms manifest an underlying disorder that cannot be observed directly (“the substantialist model”); sometimes there seems to be no underlying disorder and the diagnosis is a rearrangement of the data (“the nominalist model”). In deciding their merits in the particular case, we must identify the sources of variation; what is meant by saying that the data are independent; and what can be meant by “wrong” diagnosis and misclassification. Problems arise in human diagnosis because the data may be false, even lies; because the known list of diseases is not exhaustive; and because the probability of multiple unrelated diseases increases with age. Special difficulties arise from homeostasis (which is fundamental in defining and understanding disease) because the primary disturbances may be hard to distinguish from the homeostatic responses to them.     

Health Promotion,Health Locus of Control,and Health Behavior: Two Field Experiments1

In spite of a sizable body of research on the effects of information promotions on health knowledge and health behavior, relatively little is known about how such efforts affect change (or why they do not). This paper addresses that problem by exploring the particular role that health locus of control (HLC) beliefs play in individual responses to health promotion efforts aimed at encouraging preventive health behaviors. Two field experiments are presented. The first experiment examined the extent to which HLC beliefs are related to differences in individual levels of health knowledge following the distribution of an informational booklet on health. Internals high on health value who received the information booklet demonstrated greater health knowledge three months later than did other subjects, although this difference was greater among men than among women. The second experiment explored how HLC beliefs interact with differently framed “control” messages to promote behavior change in breast self-examination (BSE). HLC beliefs interacted with the control language of the BSE promotional message and a neutral reminder to affect subsequent BSE practice. Together, these studies suggest a more influential role for health locus of control beliefs in shaping responses to health messages than has previously been documented in field settings.     

Further explorations of common-sense representations of common illnesses

A simple method is presented for measuring people's illness cognitions--their common-sense representations of common illnesses. Data were collected from 1,628 different respondents who described a recent illness form 1 to 3 separate times over a 17-month period. A free-clustering task performed by a set of naive participants confirmed that these cognitions fall into the five components that have been previously noted: identity, time line, consequences, cause, and cure. These five components are found to be reasonably stable over time and across different illness episodes. Several consequences of these illness cognitions, in terms of changes in health-locus-of-control beliefs and different propensities to visit a doctor, are also noted. Specifically, controllable attributions for getting sick and personal responsibility attributions for getting better are associated with increased beliefs in Self-Control Over Health and decreased beliefs in Chance Health Outcomes; people with strong Identity and Cure components in their common-sense representations of common illnesses have a greater propensity to visit a doctor when feeling ill.
