A music-based HIV prevention intervention for urban adolescents

OBJECTIVE: This research examines the process of conducting and evaluating a music-based HIV prevention intervention among urban adolescents, and is informed by the information, motivation, behavioral skills (IMB) model. DESIGN: Musically talented opinion leaders were recruited to write, record, and distribute HIV prevention themed music to their peers to increase HIV prevention motivation, behavioral skills, and behaviors. In this 3-month field experiment, participants were 306 students enrolled in health classes at each of three large multiracial urban high schools (one treatment school; two control schools). MAIN OUTCOME MEASURES: Measures of HIV prevention information, motivation, behavioral skills, and behaviors, both pre- and postintervention. RESULTS AND CONCLUSION: Results indicate that the intervention influenced several aspects of HIV prevention motivation, behavioral skills, and condom use and HIV testing behaviors. This research demonstrates that the incorporation of music into HIV prevention interventions for adolescents has the potential to be effective.     

The effects of varied retrieval cues on reminiscence in eyewitness memory

Eyewitnesses sometimes recall things at later interviews that they did not recall at previous interviews (reminiscence). When these cases are argued in the courtroom, attorneys may claim (and judges may warn jurors) that eyewitnesses who provide reminiscences are necessarily inaccurate witnesses. Consequently, their testimony may be prematurely discredited or dismissed. We examined here the role of varying the retrieval cues across interviews to account for reminiscence. Participants watched a videotaped mock crime and were tested for recall on two occasions using the same or different cues. Results supported the hypothesis that varying retrieval cues increases the amount of reminiscence. Furthermore, nearly all participants exhibited some reminiscence. Finally, reminiscence was not significantly correlated with overall accuracy of testimony. These findings suggest that many of the assumptions underlying legal tactics and judges' instructions regarding reminiscent inconsistencies are erroneous.

麻醉方式的临床决策

外科手术的进步离不开麻醉的配合,麻醉方式的抉择非常重要。如果麻醉达不到预期效果,不仅可以导致手术失败、也会给患者的身心带来伤害、甚至会由此引起医疗纠纷。科技进步、社会发展应运而生微创医学、医学人文学,这是社会的进步和必然趋势,也是麻醉方式选择的理论依据。     

Heidegger's Generative Thesis

Abstract: For William Blattner, Heidegger's phenomenology fails to demonstrate how a nonsuccessive temporal manifold can ‘generate’ the appropriate sequence of world‐time Nows. Without this he cannot explain the ‘derivative’ status of ordinary time. In this article I show that it is only Blattner's reconstruction that makes failure inevitable. Specifically, Blattner is wrong in the way he sets out the explanatory burden, arguing that the structure of world‐time must meet the traditional requirements of ordinary time logic if the derivation is to succeed. He takes this to mean: mundane ‘tasks’, the contents of world‐time nows, must form a transitive series, importing back into world‐time the very structure that Heidegger says is derived by its levelling‐off. I argue, instead, that world‐time nows, seen at the level of lived content, can be quite ‘irrational’ but this is perfectly consistent with the generative thesis. Adapting Blattner's useful suggestion that temporality is sequence building or ‘iterative’ I show that iteration does not manifest itself at the level of tasks but at the ‘existential’ level of my involvement in a task. Depriving that involvement of its expressive content is what accounts for the levelling‐off of the world‐time now and thus the derivation of the ordinary concept of time.     

Heidegger and the narrativity debate

One unresolved dispute within Heidegger scholarship concerns the question of whether Dasein should be conceived in terms of narrative self-constitution. A survey of the current literature suggests two standard responses. The first correlates Heidegger’s talk of authentic historicality with that of self-authorship. To the alternative perspective, however, Heidegger’s talk of Dasein’s existentiality, with its emphasis on nullity and unattainability, is taken as evidence that Dasein is structurally and ontologically incapable of being completed via any life-project. Narrativity imports into Being and Time commitments concerning temporality, selfhood, and ethics, which Heidegger rejects. Although both positions find good exegetic support for their conclusions, they can’t both be right. In this article, I navigate a path between these two irreconcilable positions by applying insights derived from recent debates within Anglo-American literature on personal identity. I develop an alternative thesis to Narrativism, without rejecting it outright, by arguing that Dasein can be analysed in terms of what I call “narratability conditions.” These allow us to make sense of the prima facie paradoxical notion of “historicality without narrativity.” Indeed, rather than reconciling the two standard positions, I hold that the tension between them says something important about Dasein’s kind of existence. Thus I conclude that while the narrativist question “Who ought I to be?” is perfectly legitimate within limits, what the existential analysis of the limits on narratability reveals is that no answer to this question can ever be definitive.     

Detecting true and false opinions: The Devil's Advocate approach as a lie detection aid

We examined the efficacy of a new approach to detect truths and lies in expressing opinions: the Devil's Advocate approach. Interviewees are first asked an opinion eliciting question that asks participants to argue in favour of their personal view. This is followed by a Devil's Advocate question that asks participants to argue against their personal view. People normally think more about reasons that support rather than oppose their opinion. Therefore we expected truth tellers to provide more information and shorter latency times in their responses to the opinion eliciting question than to the Devil's Advocate question. Liars are expected to reveal the opposite pattern as the Devil's Advocate question is more compatible with their beliefs than is the opinion eliciting question. In Experiment 1, we interviewed seventeen truth tellers and liars via the Devil's Advocate approach and measured the difference in number of words and latency times to the two questions. Our hypotheses were supported. In Experiment 2, 25 observers were shown these interviews, and made qualitative judgements about the statements. Truth tellers' opinion eliciting answers were seen as more immediate and plausible and revealed more emotional involvement than their Devil's Advocate answers. No clear differences emerged in liars' answers to the two types of question. We conclude that the Devil's Advocate approach is a promising lie detection approach that deserves attention in future research.     

Diagnostic Comorbidity in Adults With Generalized Anxiety Disorder: Impact of Comorbidity on Psychotherapy Outcome and Impact of Psychotherapy on Comorbid Diagnoses

The current study examined the impact of comorbidity on cognitive and behavioral therapies for generalized anxiety disorder (GAD) as well as the impact of these therapies on diagnoses comorbid to GAD. Seventy-six treatment-seeking adults with principal diagnoses of GAD received 14 sessions of therapy. Most (n = 46; 60.5%) of the sample had at least one comorbid diagnosis. Although the presence of comorbid diagnoses was associated with greater severity of GAD symptoms at pretreatment, greater severity of comorbid major depression, simple phobia, and social phobia was associated with greater change in symptoms of GAD in response to treatment, with no effect on maintenance of gains during a 2-year follow-up. Further, psychotherapy for principal GAD led to a reduction in number of comorbid diagnoses and in severity of social phobia, simple phobia, and major depression at posttreatment. At 2-year follow-up severity of social and simple phobia remained below pretreatment levels, whereas severity of depression was no longer significantly below pretreatment levels. These results suggest that although people with comorbid disorders enter treatment with more severe GAD symptomatology, they demonstrate greater change, and therefore such comorbidity does not diminish the efficacy of cognitive and behavioral therapies for GAD. In addition, the impact of these treatments for GAD may generalize to reduced severity of simple phobia, social phobia, and major depression; however, gains in severity of major depression are not maintained.
