Studied the responses of 788 students at a large metropolitan university on an anonymous questionnaire concerning marihuana. Ss' attitude toward marihuana shifted from strongly negative to strongly positive as frequency of marihuana use increased. With frequency of use controlled, attitude toward marihuana was even more favorable when other drugs had been tried, and also among Ss who were religiously inactive. 74% of the Ss had at least tried marihuana and 39% reported weekly or more often use. 34% of the weekly or more often users reported no experience with "ups" and "downs," hallucinogens, or opiates, and 14% who used all 3 of these reported no use of marihuana so the causal relationship, if any, was weak.

We must enter the second decade of AIDS with the knowledge that existing public health efforts have failed to stop the disproportionate spread of HIV disease among Americans of African descent. This article presents the cold epidemiological facts which lay bare the moral tragedy that Black Americans are being killed by a disease which is almost totally preventable. This paper discusses the primary behavioral risk factors for HIV infection and the context in which HIV disease emerged in the 1980s. Additionally, we present results from cross-sectional surveys of selected black populations to demonstrate how AIDS knowledge deficits and attitudinal barriers have shaped the perceptions of Black Americans toward needle exchange programs as an HIV prevention strategy advocated by public health authorities. A model that may be utilized to educate the Black community and facilitate their involvement in the development of needle exchange policy is described.  相似文献

Data from a 1999 national telephone survey with a probability sample of English-speaking US adults (N=1,335) were used to assess how support for HIV surveillance policies is related to AIDS stigma and negative attitudes toward groups disproportionately affected by the epidemic. Anonymous reporting of HIV results to the government was supported by a margin of approximately 2-to-l, but name-based reporting was opposed 3-to-l. Compared with other respondents, supporters of name-based surveillance expressed significantly more negative feelings toward people with AIDS, gay men, lesbians, and injecting drug users. More than one third of all respondents reported that concerns about AIDS stigma would affect their own decision to be tested for HIV in the future. Implications for understanding the social construction of illness and for implementing effective HIV surveillance programs are discussed.

Increasingly, the United States is becoming internationalized as a result of sophisticated communication technologies that put us in touch with countries known previously to only a few, through economic development and multinational investment, and by the immigration of people who are sometimes fleeing hostile homelands. US citizens, like others abroad, will need to be responsive to the demands of a multiethnic, multiracial, and multinational society. The challenges of this changing world can and will range from such dilemmas as ethical decisions of who can and will have access to expensive technology that saves and prolongs life; to the development of conflict management strategies for peaceful coexistence with neighbors whose behaviors, beliefs, and values are strongly shaped by their religious, cultural, and ethnic backgrounds and socioeconomic circumstances. With the inauguration of this section, US psychology is invited to consider its contribution to meeting the needs of a changing society.

This study assessed public attitudes toward organ allocation through vignettes that were varied by patient's ability to pay (insured or uninsured), gender, and smoking history (current, former, or never). Participants were 681 adults contacted at a state driver's license office who read a vignette about a heart transplant candidate and subsequently rated their likelihood and priority of offering transplantation. Results revealed main effects for patient smoking history exclusively. Post hoc analyses for likelihood of offering transplantation revealed that participants gave higher ratings for never smokers than current smokers. For priority of transplantation, analyses revealed higher ratings for never smokers than for both former smokers and current smokers. Results suggest that public opinion about organ allocation may include the consideration of smoking history but not ability to pay or gender.

College students' perceptions of generalized social support were investigated from a developmental perspective. 262 undergraduates completed questionnaires concerning general and relationship-specific social support. Questionnaires were mailed to students' parents and a sibling. Student reports of past and present parental relationships predicted parents' questionnaire return. Parents' views of students' personal characteristics predicted students' general perceptions of social support. Relationship-specific social support perceived from father but not mother was predicted by that parent's view of the student. Students' self-views and feelings of parental acceptance, variables theoretically associated with general social support, were also predicted by parents' views. Parental views of siblings did not in general predict student variables. Results are discussed in terms of relationship-based family antecedents of social support.

Asked 163 male and 165 female students to write stories to 1 of 3 versions of M. S. Horner's Thematic Apperception Test (TAT) verbal cue used to measure women's "motive to avoid success": a successful medical student who was a single female, a single male, or a married female. Ss then answered an objective questionnaire about the cue figure. Story protocols, classified as positive, mixed, or negative on the basis of success-related content, were significantly (p  相似文献

Numerous reports on the complications of craniofacial surgery have been published in the western world. However, relatively little such information concerning Oriental populations has been documented. We therefore set out to provide a retrospective analysis of all the complications of craniofacial surgery encountered during the 10-year period of 1986 to 1995 at Seoul National University Children's Hospital, the only children's hospital in Korea. Forty-nine children underwent 57 consecutive craniofacial procedures at our institution during 1986 to 1995. A retrospective chart analysis of the frequency and types of complications was performed. Mantel-Haenszel chi-square tests were then calculated for several factors, including age at surgery, duration of surgery, intraoperative losses of hemoglobin and hematocrit, total amount of blood transfusion, and the number of complications according to year, diagnosis, and operative procedure to find any significant correlation with the incidence of complications. Mortality was 1.8%. The major complication rate was 7.0% and included cases of visual loss and persistent cerebrospinal fluid leak. Analysis revealed the presence of several trends, including an increased incidence of complications with increased patient age at surgery, duration of surgery, and intraoperative loss of hematocrit. The number of complications was also noted to increase in cases with complex craniofacial synostosis syndromes (Crouzon's, Apert's Antley-Bixler, etc.) and tumors of the orbit and cranium. Finally, complications were noted to decrease in recent years, most likely due to the increased experience of our craniofacial team. Nevertheless, statistical analysis revealed that the incidence of complications correlated significantly only with increased duration of surgery (p < 0.05). The results of our study indicate that although craniofacial surgery in the Orient carries an inherent risk for significant complications, the risk can be minimized and the rate of mortality and major complications kept to an acceptable level by a careful and experienced craniofacial team. Groups at most risk for complications are those with a long duration of surgery.  相似文献

Results of 3 experiments with 202 undergraduates suggest that feeling empathy for a member of a stigmatized group can improve attitudes toward the group as a whole. In Exps 1 and 2, inducing empathy for a young woman with AIDS (Exp 1) or a homeless man (Exp 2) led to more positive attitudes toward people with AIDS or toward the homeless, respectively. Exp 3 tested possible limits of the empathy–attitude effect by inducing empathy toward a member of a highly stigmatized group, convicted murderers, and measuring attitudes toward this group immediately and then 1–2 wks later. Results provided only weak evidence of improved attitudes toward murderers immediately but strong evidence of improved attitudes 1–2 wks later.

A laboratory experiment and 2 field studies tested the hypothesis that alcohol affects attitudes and intentions toward drinking and driving. Sober and intoxicated participants completed a questionnaire assessing their attitudes and intentions to drink and drive in a number of situations. Results indicated that when asked general or noncontingent questions, sober and intoxicated participants were equally negative about this behavior. However, when a contingency was embedded in the question (e.g., "would you drink and drive only a short distance?"), intoxicated participants were significantly less negative about drinking and driving. These results are consistent with alcohol myopia (C. M. Steele & R. A. Josephs, 1990)—the notion that alcohol intoxication decreases cognitive capacity so that people are more likely to attend to only the most salient cues.

BACKGROUND: The qualities of visual perception and of motor reaction to the visual stimulus have never been studied in reference to the type of video-camera system (2-D vs 3-D) used during laparoscopy. METHODS: The study was designed in two parts. The first evaluated the ability of the eye to discriminate how objects are spaced relative to one another. The second investigated the motor reaction to the visual stimulus in an environment where depth was the preponderent cue. The tests were performed in a pelvi-trainer in which were inserted different modules built either for visual observation (Part 1) or for evaluation of motor ability (Part 2). Variables studied during Part 1 were the time required to do the test and the number of errors committed during its performance. The variable evaluated during Part 2 was the time needed to terminate the test. Each of these two parts of the study were completed alternating the 2-D and 3-D systems. A total of 304 observations were recorded. Statistics used were the paired t-test, the independent group t-test, and the Newman-Keuls multiple comparisons test. RESULTS: Results of Part 1 of the study confirm that visual perception varies significantly among individuals (n = 10) (p < 0.05) and that a true 3-D video-camera system facilitates visual perception when compared to a 2-D system (p < 0.001). Results of Part 2 of the study also show significant differences among participants (n = 9)(p < 0.05). The true 3-D system allowed significantly faster motor performances than the 2-D system (p < 0.001). CONCLUSION: Our experiment shows that the 3-D system allowed significant improvements in the execution of the evaluated parameters. Also noted were significant differences among participants in term of visual and motor skills.  相似文献

Attitudes toward hypnosis were assessed in 75 college students. 3 weeks later the students were required to participate in an experiment in which they were tested individually on the Barber Suggestibility Scale. The scale was administered under 3 experimental treatments with 25 Ss, ? with positive attitudes toward hypnosis and ? with nonpositive attitudes, assigned randomly to each treatment. The treatments were: Task Motivating Instructions, Hypnotic Induction Procedure, Direct Suggestions (Control). The findings confirmed Hypotheses 1 and 2 which stated: (a) Ss given either brief task motivating instructions or a procedure of the type traditionally termed a hypnotic induction show greater response to suggestions than Ss given neither task motivating insructions nor a hypnotic induction; and (b) brief task motivating instructions and an extended hypnotic induction procedure both elicit high levels of suggestibility.

From 15 farms, 1242 pigs (range per farm 12-169) were sent for slaughter at known times after their last feed. The time of feeding, quantity and type of last feed, time of loading, time in transit, distance travelled, time in lairage and time of slaughter, were recorded. The mean +/- SD stomach weight and wet stomach contents weight were 0.68 +/- 0.12 and 0.55 +/- 0.45 kg, respectively. There were 148 stomachs (11.9%) with wet contents weights > 1 kg, nine > 2 kg but < 3 kg, and one weighed 3.04 kg. The means and ranges for times from last feed to loading interval, time in transport, and time in lairage were 13.6 (0-40), 3.1 (0.75-6.0) and 4.1 (2.1-12.5) h, respectively. The mean and range for distance travelled was 193.1 (43-320) km. Ten stomachs were collected at random from a further load of pigs from one farm. They had been fed 0.64 kg dry pellets and were slaughtered 18.5 h later. The mean and range for wet stomach contents weight was 0.87 kg (0.24-1.33). Samples were dehydrated and the mean calculated stomach dry matter content for the 10 pigs was 127.4 +/- 69.1 g.  相似文献

Closantel is an anthelmintic which associates with plasma albumin and is useful for the control of sheep parasites, such as Haemonchus contortus, that ingest blood. However, the utility of closantel for parasite control has been threatened by the emergence of resistance. The mechanisms of resistance are unknown. A closantel-resistant and a closantel-susceptible isolate of H. contortus were compared with respect to the distribution and metabolism of closantel. Neither strain appeared to metabolise closantel in vitro or in vivo. Following treatment of infected sheep with radioactively labelled closantel, isotope levels in closantel-resistant adult H. contortus were significantly lower than in susceptible worms. This reduced accumulation of drug could contribute to closantel resistance by mechanisms such as reduced feeding, failure to dissociate the drug-albumin complex in the gut or increased efflux of closantel from resistant worms.  相似文献

The aims of treating patients with asthma are to relieve symptoms, to prevent symptoms and exacerbations, and to prevent long-term deterioration in lung function. It is the role of medical practitioners to inform the patient what asthma is, and to develop a plan to achieve the aims for the individual, recognizing that asthma is frequently a chronic, lifelong disease. Most patients can be diagnosed, assessed for severity and causes, and treated in primary care practices, however, sometimes help from an asthma clinic of a specialist is required. The most important management decision is to determine whether the patient needs inhaled corticosteroids; subsequently, decisions about dose, duration and method of delivery of treatment can be tailored to the individual depending on the preferences and social conditions of the patient. The aim of this article is to present the latest strategies for the management of asthma and the simplest methods for their implementation. Important new strategies include careful assessment of the severity; immediate introduction of a plan that is tailored of the individual and aimed at the possible reversing of the disease; detailed instructions for management of exacerbations and the combined use of inhaled corticosteroids with a long-acting bronchodilator. It is becoming clear that these strategies obviate dependence on oral corticosteroids in newly diagnosed asthmatic patients. Furthermore, relatively low doses of inhaled corticosteroids can be used to maintain good control if used in conjunction with other therapies. The role of newly developed antagonists to leukotrienes is not yet known but it may well be useful in mild asthma and in special forms of the disease, such as those sensitive to aspirin. In the future, the most important strategy will be to prevent the disease.  相似文献

The authors evaluated the impact of receiving social support on subsequent levels of perceived social support and psychological distress in 2 independent samples of victims of severe natural disasters: Hurricane Hugo (n?=?498) and Hurricane Andrew (n?=?404). A social support deterioration deterrence model was proposed that stipulated that postdisaster mobilization of received support counteracts the deterioration in expectations of support often experienced by victims of major life events. LISREL analyses of data collected 12 and 24 months after Hugo and 6 and 28 months after Andrew provided strong evidence for the hypothesized model: Perceived support mediated the long-term effects on distress of both scope of disaster exposure and postdisaster received support. Theoretical and application issues of social support are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)  相似文献

This study examined the mediating effects of the self-stigma associated with seeking counseling and attitudes toward seeking counseling on the link between perceived public stigma and willingness to seek counseling for psychological and interpersonal concerns. Structural equation modeling of data from 676 undergraduates indicated that the link between perceived public stigma and willingness to seek counseling was fully mediated by self-stigma and attitudes. Perceptions of public stigma contributed to the experience of self-stigma, which, in turn, influenced help-seeking attitudes and eventually help-seeking willingness. Furthermore, 57% of the variance in attitudes toward counseling and 34% of the variance in willingness to seek counseling for psychological and interpersonal concerns were accounted for in the proposed model.

Conducted an experimental simulation of an internation conflict in which 34 4-man teams participated. Ss were 136 undergraduates. Each team was subdivided into 2 decision makers (central roles) and 2 information handlers (peripheral roles). In keeping with the 1971 attitude change theory of B. E. Collins and M. F. Hoyt, it was predicted that this task allocation, with a possible additional factor of physical separation between subteams, would be a determinant of the players' emergent attitudes toward an opponent team. Results are consistent with the prediction. Teams which engaged in actions with aversive consequences for an opponent held more negative attitudes toward that opponent than teams which (although equal in all other respects) were prevented from directly engaging in these actions.
