Independence of neophobia and taste aversion learning     

Norman S. Braveman  Paul S. Jarvis 《Learning & behavior》1978,6(4):406-412

Animals were presented with (1) one solution which differed from that of the test solution, (2) a series of distinctly flavored solutions whose flavors differed from that of the test solution, or (3) with a flavored solution whose flavor was the same as that of the test solution. When animals received the solution whose flavor was the same as that of the test solution prior to a test for neophobia and prior to a conditioning trial, neophobia was reduced and aversions were weakened. However, when animals received a solution or a series of solutions whose flavors differed from that of the test solution, neophobia was reduced but conditioned aversions were unaffected. Presentations of solutions that differed from the test solution following aversion formation left the association between the taste of the test solution and the effects of the aversion-inducing treatment intact. In a final experiment it was discovered that neophobia was reduced as much when animals drank solutions whose flavors changed every third day as when they drank the same solution throughout testing.  相似文献   

Language use in kindergarten science lessons: language production and academic language during a video feedback coaching intervention in kindergarten science lessons     

Astrid Menninga  Marijn van Dijk  Annemie Wetzels  Henderien Steenbeek  Paul van Geert 《Educational Research and Evaluation》2017,23(1-2):26-51

This paper aims to gain insight into language production and academic language of 4- and 5-year-old students and their teachers in the course of a teacher intervention during kindergarten science education. The study is based on videotaped classroom observations, and specifically focuses on the academic language use of students (N_intervention = 18, N_controls = 26) and teachers (N_intervention = 5, N_controls = 5). The results suggest that this general teacher intervention yields interesting changes in language use and production. Patterns of change over time confirm the idiosyncratic and non-linear nature of these changes. Science lessons represent an appropriate context in which to acquaint students with academic language, which can be used as a basis to build upon more sophisticated language skills.  相似文献   

Principal Recruitment: An Empirical Evaluation of a School District’s Internal Pool of Principal Certified Personnel   总被引：1，自引：0，他引：1  

Paul A. Winter  James S. Rinehart  Marco A. Muñoz 《Journal of Personnel Evaluation in Education》2002,16(2):129-141

Applicant pools for principal vacancies are shrinking nationwide. This shortage of job applicants requires school districts to evaluate their internal pools of principal certified personnel. In this study, 194 certified individuals from a large school district responded to a survey measuring attraction to the job of principal, current job satisfaction versus expected satisfaction in the job of principal, barriers to pursuing the job, and recommended changes in the job. Few participants intended to apply for principal vacancies due to age (median=51), lack of self-reported capability to do the job, and satisfaction with the current job. Participants perceived their job satisfaction would decrease on assuming the job of principal relative to factors such as time with family and job security, and increase relative to factors such as salary and opportunity to experience varied activities. Implications for principal recruitment and recommendations for restructuring the job are discussed.  相似文献   

Role of recognition of prior learning for emerging economies: learning from a four sector pilot project in India     

Sandra Rothboeck  Paul Comyn  Partha S. Banerjee 《Journal of Education & Work》2018,31(4):394-408

Recognition of prior learning (RPL) has increasingly been recognised as a useful way to certify experience and competencies gained in the workplace informally. Particularly pertinent is RPL in the context of international migration or in economies, where system reforms seek to overcome challenges related to access to formal training and qualifications. India has the goal to skill 300 million of its growing workforce and provide them access at various levels to certification and further learning opportunities. As a part of the overall system reforms, the Government of India, jointly with the ILO, pilot tested RPL in four sectors in collaboration with the industry and built the foundation for wider replication for another 26 growth sectors by undertaking a tracer study and evaluation. This paper can empirically establish that RPL has had a positive effect on income opportunities, occupational safety, social status and openness to further learning. The paper further discusses the challenges encountered during the implementation of the RPL projects before concluding with recommendations, highlighting the aspects required for quality RPL in an emerging economy. It closes by emphasising the importance of conducting tracer studies to determine impact and the need to provide complementary training during the RPL process.  相似文献   

Deconstitutive rhetoric: The destruction of legal personhood in the Global War on Terrorism     

Michael Paul Vicaro 《Quarterly Journal of Speech》2016,102(4):333-352

This essay examines a set of memoranda, speeches, and other official discourse issued during the Global War on Terrorism that transformed the legal paradigm under which the enemy was defined and authorized new norms of conduct previously prohibited by law. It argues that these texts employ “deconstitutive rhetoric,” defined as discursive action that undermines the existing legal status of those to whom it refers and produces a disarticulate, destitute subject by denying the individual access to the civic forums in which rhetorical agency may be exercised. The essay begins with an analysis of the use of deconstitutive rhetoric in the decision to legally re-define Afghanistan as a “failed state” in order to absolve the United States of treaty obligations with that nation. It then addresses the emergence of “unlawful enemy combatant status,” a new legal category not recognized under the international laws of war. The essay concludes with a discussion the Obama administration’s detention and drone strike policies, which have continued to use deconstitutive rhetoric to undermine the legal status of those captured and killed in the Global War on Terrorism.  相似文献   

Sameness-difference judgments inSaimiri sciureus based on volumetric cues     

Paul Czerny  Roger K. Thomas 《Learning & behavior》1975,3(4):375-379

The rationale was to apply Piaget’s theory and methods to the study of the phylogenetic development of cognitive abilities. It was asked whether squirrel monkeys have the prerequisite skills for conservation of quantity, and, specifically, whether they might respond differentially to equivalent and unequivalent volumetric cues. All monkeys responded significantly and differentially to pairs of identical objects or pairs of objects similar only in volume vs. pairs of objects which differed in volume. It was concluded that squirrel monkeys have the prerequisite skills for the conservation of quantity. Discussion included methodological problems associated with demonstrating conservation in nonhumans as well as the potential usefulness of Piaget’s theory for phylogenetic studies of intelligence.  相似文献

Practicum Placement in a Counseling-Employment Agency for Disadvantaged Youth     

Paul A. Payne  Robert B. Mills 《Counselor Education & Supervision》1970,9(3):189-193

In order to emphasize the development of skills in helping the culturally disadvantaged, graduate students were given practicum placement in a Department of Labor-financed agency which gave counseling and employment training to disadvantaged youth. Students attended staff meetings, interviewed staff members concerning the work they performed, and discussed client contacts with caseworkers, in addition to interviewing agency clients. Increased awareness of problems, broadened conceptualizations, and expansion of interpersonal skills were seen as advantages of the practicum. Limitations included some lack of goal clarity and inefficiency of time use in dealing with this clientele.  相似文献
