Twelve pigeons were trained on matching-to-sample using either a 0-, 5-, 15-, 25-, or 60-sec intertrial interval. Eight of these 12 pigeons were given one of the following intertrial interval changes: 0 to 60, 0 to 5, 5 to 0, 60 to 0, 15 to 25, 5 to 15, 60 to 5, 5 to 1, 1 to 5, 1 to 25, and 25 to 1 sec. Most intertrial interval changes were repeated at least once. The 0-sec intertrial interval subjects failed to match beyond chance levels, while other intertrial interval values resulted in matching acquisition. Changes from 0 sec to other intertrial interval values increased and changes to 0 sec decreased matching performance. Changes to intertrial interval values other than 0 sec resulted in little change in matching accuracy once stable performance had been attained. 相似文献

This study examined risk factors associated with acquisition of sexually transmitted diseases (STDs) including HIV in adolescents, using the AIDS Risk Reduction Model. The study participants were 985 students who were 54% female, ethnically/racially diverse, had a mean age of 14.7 years, and were mostly 9th graders (74%). Logistic regression was used to predict sexual experience. Linear regression was used to predict risky sexual behaviors and condom use within the previous month. The results indicate that demographic factors are associated with being sexually experienced, but few demographics are associated with specific STD-related risk behaviors. STD and AIDS knowledge are not associated with any risk behaviors. Use of alcohol and drugs is associated significantly with being sexually experienced and sexual risk. The results also indicate that peer affiliation, perceptions of peer norms, perceptions of risk, perceptions of self-efficacy, and social support are associated with STD-related risk among sexually experienced youth. 相似文献

Narratives by survivors of abuse offer compelling entries into the experiences of abuse and its effects on health. Reading such stories can enlarge the clinician's understanding of the complexities of abuse. Furthermore, attention to narrative can enhance the therapeutic options for abuse victims not only in mental health arenas, but also in other medical contexts. In this article we define the genre of survivor narratives, examine one such narrative in particular (Push by Sapphire, 1996), and explore the clinical implications of narrative in abuse victims' clinical care. 相似文献

Queer theorists most commonly challenge conventional pictures of the stable self by pointing out ways in which the self can be opened towards others (i.e. “spatially” disrupted). This essay demonstrates how the recent work of Paul North on “primal distraction” supplies material for an expansion of this critique by allowing theorists to better understand how the self can also be “temporally” disrupted, its apparently smooth progression through time being in fact punctuated by fundamental discontinuities. Taking up a recent monograph by Kent Brintnall as a case study in the fruitfulness of bringing North’s work to bear on queer studies of religion and subjectivity, the article discusses distraction’s relevance not just for understanding queer temporality but also for reimagining theological problems in areas such as soteriology, eschatology, and mysticism. The article thus both sketches out a particular project for queer theory and points to the broader research programs in theory and theology that such a project enables. 相似文献

We established a general genetic counseling clinic (GCC) to help reduce long wait times for new patient appointments and to enhance services for a subset of patients. Genetic counselors, who are licensed in Tennessee, were the primary providers and MD geneticists served as medical advisors. This article describes the clinic referral sources, reasons for referral and patient dispositions following their GCC visit(s). We obtained patients by triaging referrals made to our medical genetics division. Over 24 months, our GCC provided timely visits for 321 patients, allowing the MD geneticists to focus on patients needing a clinical exam and/or complex medical management. Following their GCC visit(s), over 80 % of patients did not need additional appointments with an MD geneticist. The GCC allowed the genetic counselor to spend more time with patients than is possible in our traditional medical genetics clinic. Patient satisfaction surveys (n?=?30) were very positive overall concerning the care provided. Added benefits for the genetic counselors were increased professional responsibility, autonomy and visibility as health care providers. We conclude that genetic counselors are accepted as health care providers by patients and referring providers for a subset of clinical genetics cases. A GCC can expand genetic services, complement more traditional genetic clinic models and utilize the strengths of the genetic counselor health care provider. 相似文献
