In three experiments, using a total of 120 albino rats, we assessed whether transportation cues might evoke some of the freezing (i.e., defensive immobility) that we see in a context on a day following a footshock given immediately after placement in that context. The results suggested that immediate shock could directly condition strong fear to both simulated and actual transport cues. Although conditioning to transport cues explains some of the freezing that is seen on the test day, it does not explain all of it. We also found evidence that some of the freezing is due to conditioning to permanent features of the context in which the immediate shock is given. The results support a role for transport cues in theories of context conditioning and argue against shock-processing accounts of the conditioning deficit that results from immediate shock.  相似文献

Over the last twenty-five years, there has been an increase in the availability of published checklists and schedules which allow practitioners to identify the strengths of children and young people, including those with special educational needs. While helpful, these assessments are unable to tell us about the nature of contextual factors which support the expression of particular strengths. In this study, we took a situative perspective to explore how specific classroom practices facilitated strengths. A multiple case study design was used to analyse practices nominated by three children/young people with special educational needs. Qualitative analysis revealed how aspects of practice afforded the opportunity for each child to participate in ways which they equated with their strengths. This style of strength-based assessment led to a more sustained examination of supportive practice features than would have been achieved through interview alone.  相似文献

This study compared features and determined which of four end-user systems (PaperChase, GRATEFUL MED, Med-Base, or Compact Cambridge: MEDLINE) would best serve the Medical Sciences and Optometry Libraries of Indiana University in providing biomedical information to faculty and graduate students through MEDLINE. Cost, ease of use, retrieval, training needs, equipment requirements, and adequacy of documentation were examined. The study consisted of a comparison of the features of each system based on available documentation; a controlled search performed by the investigators on each system and on regular NLM MEDLINE; and a user study based on observations, questionnaires, and interviews with eleven library patrons who performed the same search of their choice on each of the four systems.  相似文献

The authors explored the relationship of gender, gender role identity, and type of relationship—same‐sex friendship, cross‐sex friendship, or romantic relationship—to relationship behaviors and beliefs among 429 college students. They discuss implications for individual and group counseling, consultation, and primary prevention on college campuses.  相似文献

Examining the Detroit episode of Anthony Bourdain’s CNN show, Parts Unknown, this study illuminates how the collective memory of the American dream is ironically projected onto Detroit, the metonymic city of America past. In order to identify the nostalgia of the American dream narrated in the show, we apply the dialectical approach to intercultural communication suggested by Martin and Nakayama and propose the imagined dialectics. Throughout our analyses, we contend that the imagined dialectic narrated in the Parts Unknown episode nostalgically frames Detroit’s past, which inevitably fetishizes its present. We ultimately argue that the nostalgia of the American dream epitomizes the lack of an intercultural and interregional understanding within the US and prevents us from democratic discussion for the betterment of the urban lives.  相似文献

This study reports on the content validation of the Community College Student Success Program Inventory (CCSSPI), a structured interview protocol for program personnel, designed to serve as a tool for researchers and practitioners alike to account for critical features of various types of student success programs in detailed and comparable ways across multiple sites. In all, 20 subject matter experts (SMEs) rated the relevancy and clarity of each item to ascertain essential program features. Content validity index (CVI) and scale-level index scores (S-CVI) were calculated. Results showed high to moderately high validity for items related to course goals, logistics, skills-focused curricular items, and academic and student services. Other contingent facets—collaborative and contextualized learning, co-curricular and community activities, ancillary instruction, and instructor role—were rated as less valid, depending on program goals. The instrument is recommended for use in multisite qualitative or mixed-methods research and institutional improvement.  相似文献
