Competition between ethanol-induced reward and aversion in place conditioning     

Cunningham CL  Smith R  McMullin C 《Learning & behavior》2003,31(3):273-280

Previous place conditioning studies in mice have shown that injection of ethanol immediately before a conditioned stimulus (CS+) produces conditioned preference, whereas injection of ethanol immediately after CS+ produces conditioned aversion. In the present experiments, we examined the learning that occurs when ethanol is injected in “ambiguous“ procedures that provide the opportunity for both types of conditioning. When ethanol was given midway through the CS (Experiments 1 and 2) or both before and after the CS (Experiment 3), the direction of place conditioning was the same as when mice were exposed only to whichever contingency occurred first (a primacy effect). That is, injection of ethanol in the middle of the CS conditioned aversion, whereas injection both before and after the CS conditioned preference. Because these results support the idea that ethanol elicits both aversive and rewarding effects, they are most consistent with conditioning theories that conceptualize unconditioned stimuli (USs) as events that can activate multiple representational components.  相似文献   

An Exploratory Evaluation of Conjoint Behavioral Consultation to Promote Collaboration Among Family,School, and Pediatric Systems: A Role for Pediatric School Psychologists

Pediatric school psychology is a relatively new subspecialty in the field; however, few specific, prescribed roles have been articulated, and fewer have yielded preliminary efficacy data. In this exploratory study, the acceptability and potential efficacy of conjoint behavioral consultation (CBC) as a model for linking families, schools, and pediatric settings to address concerns for children with medical issues were evaluated. Twenty-nine children, their parents, teachers, and consultants were involved in conjoint consultation, a model of cross-system collaboration to address shared concerns of medically referred children. In this structured indirect service delivery model, parents, teachers, and school psychology pediatric consultants worked collaboratively in interdisciplinary problem solving and joint decision making with extensive input regarding medical issues from a developmental pediatrician. Outcome measures included parent and teacher observations of child functioning across home and school settings as a result of consultation-mediated interventions and social validity indices assessing acceptability and consumer satisfaction. Results suggested that CBC is a socially valid procedure for addressing concerns of medically referred children across home and school systems. Both parents and teachers reported the consultation process to be highly acceptable. Preliminary effect size analyses of child outcomes, derived from uncontrolled case study designs, suggest generally positive effects across home and school, although limitations with the methodology preclude conclusive statements. Research is needed to determine the contexts and conditions under which the model is more or less effective using rigorous controlled trials.  相似文献

Power,Bodies and Identity: How different forms of physical education construct varying masculinities and femininities in secondary schools     

Carrie Paechter 《Sex education》2013,13(1):47-59

Physical education (PE) lessons are an important arena for the construction and consolidation of dominant and subordinate masculinities and femininities within schools. The gym, sports hall, playing field and associated areas such as changing rooms and showers function as sites both for the gendered display of hegemonic forms of heterosexual masculinity and for the subordination of alternatives. Femininities of different sorts are also played out through the acceptance and refusal of different forms of school PE and out-of-school exercise activities. This paper considers how different forms of physical education and sports in schools contribute to the construction and perpetuation of different forms of heterosexual masculinities and femininities. In it I attempt to map Frank's (1991, 1995) ideal types of bodily usage against activities in the male and female traditions of school PE. I look at the gender marking of Frank's ideal types and the corresponding PE, sports and fitness activities and at how the different bodily usages encouraged by different forms of secondary school PE permit and encourage the development of particular masculinities and femininities while discouraging others.  相似文献   

The Relationship Between College Students' Self-Reports of Class Participation and Perceived Instructor Impressions     

Scott A. Myers  Sean M. Horan  Carrie D. Kennedy-Lightsey  Paul E. Madlock  Robert J. Sidelinger  Kerry Byrnes 《Communication Research Reports》2013,30(2):123-133

The purpose of this investigation was to identify the extent to which college students' self-reports of their in-class participation are related to their impressions of instructors (i.e., credibility, attractiveness, and homophily). Participants were 223 undergraduate students enrolled in an introductory communication course at a large Mid-Atlantic university. Students' self-reports of their in-class participation were positively correlated with perceived instructor social attractiveness, physical attractiveness, background homophily, and attititude homophily, but not with perceived instructor competence, character, caring, and task attractiveness. Furthermore, class size, perceived instructor social attractiveness, and perceived instructor background homophily emerged as significant predictors of in-class participation.  相似文献   

This Little Piggy Went to Press: The American News Media's Construction of Animals in Agriculture     

Carrie Packwood Freeman 《The Communication Review》2013,16(1):78-103

This textual analysis examines the representations of farmed animals in national print and broadcast news discourse in over 100 stories published from 2000 to 2003. Findings show these American news media largely support the speciesist status quo by favoring elite viewpoints and failing to provide balance. Although exceptions are provided, news media often objectify nonhuman animals discursively through: 1) commodification, 2) failure to acknowledge their emotional perspectives, and 3) failure to describe them as inherently valuable individuals.  相似文献   

An Investigation of Student Response to a Potential Tuition Cap Increase at Casper College     

Elizabeth Davis  Thomas Aitchison  Eric Allen  Carrie Gomez  Sheree Laird  Kaja Raczyńska 《Community College Journal of Research & Practice》2013,37(2):192-198

Wyoming Community College Commission policy currently states any student enrolled for more than 12 credit hours will be charged tuition for only 12 credit hours. This policy is referred to as the tuition cap. In November 2010, the commission discussed increasing the tuition cap to 15 credits. An increase from 12 to 15 credits would have represented a 25% increase in tuition for students enrolled for 15 or more credits. Casper College president Dr. Walter Nolte commissioned a study to examine the impact such an increase would have on Casper College and its students. A survey instrument was designed to determine if students carrying more than 12 credit hours would reduce their enrollment credits and what sources of funding they would seek to defray the increased cost. Using a multistage sampling design, a sample of 67 Casper College course sections was selected to respond to the survey. The data were analyzed with logistic regression models, and the estimates were adjusted using sampling weights and a finite population correction. Analysis indicated that 42% of Casper College students would reduce their credit hours by an average of 3.3 credits. Approximately 58% of students would seek additional scholarships and 63% would seek increased work hours. The results of the study were presented to the Wyoming Community College Commission on October 28, 2011. In December 2011, the Commission announced a decision not to increase the tuition cap.  相似文献

Social Work and Law Interdisciplinary Service Learning: Increasing Future Lawyers’ Interpersonal Skills     

Stephanie K. Boys  Stephanie Q. Quiring  Evan Harris  Carrie A. Hagan 《Journal of Teaching in Social Work》2013,33(4):410-424

Social workers and attorneys both interact with persons from diverse backgrounds every day, yet although interpersonal skills are an essential focus of social work education, these skills are not addressed in legal education. Interdisciplinary courses in which social workers and lawyers learn interpersonal skills together and have an opportunity to practice them through service learning opportunities are a way to remedy a gap in legal education. The authors describe a project recently piloted at a large midwestern university in which law and graduate social work students participated in an interdisciplinary course with a service learning component requiring students to work together on cases. As one component of the clinic’s assessment, all students were pre- and posttested via an interpersonal skills survey. The law students showed statistically significant improvement in interpersonal skills at the end of the course. The results indicate a need for increased support for interdisciplinary education, specifically partnerships between the professions of law and social work.  相似文献
