In a discrete-trial two-choice conditional discrimination task, pigeons which received food for a correct choice following the presentation of one cue and water for a correct choice following another cue performed better than pigeons which received food and water equally often in both cases when delays of several seconds intervened between the conditional cue and choice stimuli presentations. These results suggest that feedback properties of reinforcer-specific expectancies can be important in conditional discrimination learning in pigeons. An additional finding was that wild-caught pigeons regularly exhibited a higher percentage of correct choices than domestic subjects. 相似文献

This research project used Freedom of Information requests to obtain public records from Alabama institutions about challenges to materials in public schools and public libraries. Challenges occur when a patron objects to certain content. In this analysis, we examine the records of challenges. The research questions were as follows: How many challenges occur in public schools and libraries? What is the nature of these challenges? Are there institutional or demographic factors that are correlated to the occurrence of challenges? In this exploratory study, the number of reported challenges was surprisingly low. We investigated whether reported challenges were related to certain institutional or demographic factors, but did not find any discernible relationships. The data suggest that most challenged material is retained, but that librarians may be self-censoring to reduce controversy in their collections. 相似文献

This paper examines responses to a framing shift from carbon capture and storage (CCS) to carbon capture, utilization, and storage (CCUS) within science and engineering professionals’ communication. We argue that the framing shift is a breach in the rhetorical boundaries of the CCS professional community that calls forth negotiation through responses that proactively support, resist, or acquiesce. This study offers a heuristic for examining scientific framing in expert-to-expert internal scientific rhetoric. It also contributes to contemporary research on the intersection of rhetoric of science and science, technology, and society; the social dimensions of CCS; energy communication; and applied communicative practices in scientific communities. 相似文献

The authors recruited college students (N = 648) and investigated relationships among academic and social self–efficacy, relational aggression from parents and peers, and nonsuicidal self–injury (NSSI). Results indicated that both types of self–efficacy were related inversely to NSSI. Academic self–efficacy mediated the relationship between parental emotional abuse and NSSI, whereas social self–efficacy mediated the relationship between peer victimization and NSSI. Clinical implications of these findings for college counselors are discussed. 相似文献

In late 2013 a new curriculum for Civics and Citizenship education was published by the Australian Curriculum and Assessment Reporting Authority for use in Australian schools. In line with previous curricular initiatives concerning education for citizenship in Australia a key rationale behind the new subject is the education of “active citizens”. Research evidence over the last 25 years paints a mixed picture regarding the extent to which the translation of policy intent has been successfully implemented within Australian schools. Exploring the new subject of Civics and Citizenship in Australia in the context of previous initiatives and existing research evidence, we explore the contested and complex nature of active citizenship around three key issues – the scope and form of action that constitutes citizenship in one’s communities, how young people themselves conceptualize and experience participation, the potential that active citizenship opportunities are interpreted as being synonymous with the use of active teaching and learning methods. On this basis we argue that the new curriculum provides some optimism for those committed to education for citizenship in Australian schools, but that this optimism needs to be tempered with a degree of caution. 相似文献
