Effects of varying trial distribution,intra- and extramaze cues,and amount of reward on proactive interference in the radial maze     

J. S. Cohen  S. Reid  K. Chew 《Learning & behavior》1994,22(2):134-142

Rats are typically less accurate in their arm selections in the radial maze over successive trials in a session (Roberts & Dale, 1981). In the present study, rats’ choice accuracy declined when such trials were separated by 2-min (massed) but not by 2-h (spaced) intertriai intervals. Changing intramaze visual/tactile arm stimuli (Experiments 1 and 3) or extramaze landmark stimuli (Experiment 4) between trials weakened the massed-trials effect, but changing the number of food pellets per arm, either alone or in conjunction with changes in intramaze cues (Experiments 2 and 3), did not. The rats also tended to avoid the spatial locations of their last four choices on a previous trial during their first four choices on a current trial, and more so with massed than with spaced trials. These findings indicate that intertriai proactive interference (PI) occurred only with massed trials and was weakened by changing intra- and extramaze cues between such trials.  相似文献   

Exploiting the Links between Theory and Practice: Developing Students' Cross-cultural Understanding through an International Study Tour to China     

Kate Hutchings  Pamela Jackson  Rob McEllister 《高等教育研究与发展》2002,21(1):55-71

This paper describes and critiques a study tour to China of undergraduate and postgraduate business students in a large business faculty in a university with an emerging focus on internationalisation through building links with global business and industry. The study tour was designed to fit with the emerging trend towards internationalisation of business education wherein universities perceive themselves as being international universities based in one city rather than city-based universities who have international students. The literature on the difficulties of cross-cultural understanding and adjustment when business people sojourn to other countries is well documented. Yet, the same difficulties being encountered by students on short-term cultural immersion tours are yet to be adequately documented. This paper serves to address this gap in the literature by examining the experiences of 50 Australian and international students when confronted with a three week immersion into China's business, cultural and social practices. The paper explores the contributions of the study tour to academic understanding of globalisation.  相似文献   

Social Constructivism and Asynchronous Text-Based Discussion: A Case Study with Trainee Teachers     

Kate Hawkey 《Education and Information Technologies》2003,8(2):165-177

The paper reports a case study using asynchronous text-based discussion. It considers the role of the tutor and discusses the extent to which online discussions can facilitate social constructivist approaches to instruction and the creation of knowledge. Participants were 17 trainee teachers studying on a post graduate teaching course. The asynchronous text-based discussion (using e-blackboard) focused on planning for progression in children's learning in history and culminated in the trainee teachers writing individual assignments on the topic. The paper analyses the different types of contributions made and reports on the trainees' evaluations of the benefits and limitations of using e-blackboard. It concludes with recommendations and areas for further research.  相似文献   

Grant‐maintained Heads’ Reflections on Opting Out     

Jonathan Cauldwell  Ivan Reid 《Educational studies》1996,22(2):245-260

This article summarises the views of 222 grant‐maintained (GM) school's head teachers’ experience of, and reasons for, their schools opting out of local authority control. The survey was conducted on the first 499 secondary schools to go GM. The article investigates issues such as admissions, finances and also the effects of GM status (GMS) on the relationships with, and roles of, local education authorities, the Department for Education, parents and governors. The article provides an overview of moves to GMS and highlights prior aims and reflections.  相似文献   

Audiogenic seizures in mice: Asymmetries of the preconvulsive running pattern and subsequent seizure     

Howard M. Reid  Robert L. Collins 《Learning & behavior》1982,10(3):321-324

Asymmetries in the progression of unilaterally and bilaterally induced audiogenic seizures were examined in DBA/2J and SJL/J mice. Both strains were found to exhibit consistent asymmetries in direction(s) of running as well as in the side of fall during a convulsion. This correspondence suggests that the bursts of running are an integral part of an audiogenic seizure. The incorporation of information on asymmetries of the locomotor prelude in future studies should prove valuable for understanding the physiological mechanisms of audiogenic seizure.  相似文献   

The recursive practice of research and teaching: reframing teacher education     

Rebecca Miles  Narelle Lemon  Donna Mathewson Mitchell  Jo-Anne Reid 《Asia-Pacific Journal of Teacher Education》2016,44(4):401-414

As a field, Teacher Education has lived with continued criticism from governmental and research bodies on the quality of professional preparation and the lack of a strong research base. We respond to such criticisms by considering possibilities for further exploration of the research of practice and the practice of research in both initial and continuing teacher education. As both a theoretical and methodological challenge, this is tied recursively with research and practice in teacher education, for teacher educators, about teacher education. We draw on the theoretical resources of practice theories, to argue that teacher education practice must be informed by the study of the practice of teaching as well as research addressing the teaching of practice. In conclusion, we make a methodological case for reframing the roles of teacher and researcher within a “thirdspace” to consider the practice of researching teaching as recursive and always regenerative.  相似文献   

Correlates of Work-Life Balance for Faculty Across Racial/Ethnic Groups     

Nida Denson  Katalin Szelényi  Kate Bresonis 《Research in higher education》2018,59(2):226-247

Very few studies have examined issues of work-life balance among faculty of different racial/ethnic backgrounds. Utilizing data from Harvard University’s Collaborative on Academic Careers in Higher Education project, this study examined predictors of work-life balance for 2953 faculty members from 69 institutions. The final sample consisted of 1059 (36%) Asian American faculty, 512 (17%) African American faculty, 359 (12%) Latina/o faculty, and 1023 (35%) White/Caucasian faculty. There were 1184 (40%) women faculty and 1769 (60%) men faculty. The predictors of worklife balance included faculty characteristics, departmental/institutional characteristics and support, and faculty satisfaction with work. While African American women faculty reported less work-life balance than African American men, the reverse was true for Latina/o faculty. In addition, White faculty who were single with no children were significantly less likely to report having work-life balance than their married counterparts with children. Faculty rank was a significant positive predictor of work-life balance for all faculty. Notably, the findings highlight the importance of department and institutional support for making personal/family obligations and an academic career compatible. Institutional support for making personal/family obligations and an academic career compatible was consistently the strongest positive predictor of perceived work-life balance for all faculty. In addition, satisfaction with time spent on research had positive associations with work-life balance for all faculty, highlighting how faculty from all racial/ethnic backgrounds value being able to spend enough time on their own research.  相似文献   

Navigating the discursive tensions of the public university: the case of a South African student     

Kate le Roux 《Teaching in Higher Education》2019,24(2):231-247

As public universities seek to be locally responsive and compete internationally, tensions arise between expansion and equity, and between discourses of neoliberalism and social justice. This article focuses on how students navigate these tensions, and the implications for how they can act, interact and be. Norman Fairclough’s three-level view of the social and language, and his method of critical discourse analysis are used to analyse longitudinal interviews with an undergraduate science student. This student is, on account of his home and schooling, considered ‘historically marginalised’ at an historically-white, English-medium South African university. The results show how the student navigates multiple positionings that draw on notions of class, language, independence, progress, choice, care, and so on. It is argued that while universities should support students to navigate some of these tensions, there is a need to re-imagine structuring discourses related to the ‘normal’, ‘independent’ university student.  相似文献   

Prediction of maximal oxygen uptake in sedentary males from a perceptually regulated, sub-maximal graded exercise test   总被引：2，自引：0，他引：2  

Eston R  Lambrick D  Sheppard K  Parfitt G 《Journal of sports sciences》2008,26(2):131-139

The purpose of this study was to assess the validity of predicting the maximal oxygen uptake (VO2(max)) of sedentary men from sub-maximal VO2 values obtained during a perceptually regulated exercise test. Thirteen healthy, sedentary males aged 29-52 years completed five graded exercise tests on a cycle ergometer. The first and fifth test involved a graded exercise test to determine VO2(max). The two maximal graded exercise tests were separated by three sub-maximal graded exercise tests, perceptually regulated at 3-min RPE intensities of 9, 11, 13, 15, and 17 on the Borg ratings of perceived exertion (RPE) scale, in that order. After confirmation that individual linear regression models provided the most appropriate fit to the data, the regression lines for the perceptual ranges 9-17, 9-15, and 11-17 were extrapolated to RPE 20 to predict VO2(max). There were no significant differences between VO2(max) values from the graded exercise tests (mean 43.9 ml x kg(-1) x min(-1), s = 6.3) and predicted VO2(max) values for the perceptual ranges 9-17 (40.7 ml x kg(-1) x min(-1), s = 2.2) and RPE 11-17 (42.5 ml x kg(-1) x min(-1), s = 2.3) across the three trials. The predicted VO2(max) from the perceptual range 9-15 was significantly lower (P < 0.05) (37.7 ml x kg(-1) x min(-1), s = 2.3). The intra-class correlation coefficients between actual and predicted VO2(max) for RPE 9-17 and RPE 11-17 across trials ranged from 0.80 to 0.87. Limits of agreement analysis on actual and predicted VO2 values (bias +/- 1.96 x S(diff)) were 3.4 ml x kg(-1) x min(-1) (+/- 10.7), 2.4 ml x kg(-1) x min(-1) (+/- 9.9), and 3.7 ml x kg(-1) x min(-1) (+/- 12.8) (trials 1, 2, and 3, respectively) of RPE range 9-17. Results suggest that a sub-maximal, perceptually guided graded exercise test provides acceptable estimates of VO2(max) in young to middle-aged sedentary males.  相似文献   

Regional creative industries policy-making under New Labour     

David Lee  David Hesmondhalgh  Kate Oakley  Melissa Nisbett 《Cultural Trends》2014,23(4):217-231

This article analyses creative industries policy in the English regions under New Labour (1997–2010). It examines the ideas behind regional creative industries policies (RCIPs) and their implementation. Focusing on the activities of the English regional development agencies, the primary bodies responsible for the implementation of creative industries policy in the British regions, the article places regional cultural policy during the New Labour period within its broader political, social and economic contexts. It explains and evaluates New Labour's RCIPs, arguing that creative industries policy at the regional level changed over the course of New Labour's three terms of office, becoming increasingly economistic at the expense of a more social democratic vision of regional equality and democracy. We identify three issues that were problematic for New Labour's RCIP: a reliance on the idea of “clusters”, commercialisation and shifting regional governance.  相似文献
