Sexual imprinting: The stability of mate preference in Japanese quail (Coturnix coturnix japonica)     

James E. Gallagher  Maureen Ash 《Learning & behavior》1978,6(3):363-365

This study investigated the persistence of a mate preference that resulted from early social experience.Coturnix males that achieved an imprinting criterion of selecting an imprint object (an albino conspecific hen) in 8 of 10 trials were then given one of three intervening treatments. Subjects were housed for 10 days with only normal hens or albino and normal hens, or they were isolated for the treatment period. A comparison of subsequent preference for the albino in a second series of 10 choice tests indicated that the strength of the imprinted bond is weakened with respect to the type of intervening experience. This outcome is discussed in terms of the persistence construct of the imprinting process.  相似文献

Quality in an Integrated Rural Development Program: the Sierra Leone experience     

Kingsley Banya 《Assessment & Evaluation in Higher Education》1995,20(2):213-224

As part of a longitudinal research study started in 1984, the purpose of this paper is to critically examine the issue of quality in an Integrated Rural Development project in Sierra Leone. An in-depth study was conducted (1990-93) to assess pre-service teacher quality, using two major indices: teacher knowledge base of subject-matter and teacher beliefs about teaching and classroom management. The results indicate that quality is affected by what knowledge teachers possess in a given subject area and their perceptions of teaching. This research is a departure from the traditional areas of looking at quality in education, that is from what happens to students in the education process to the issue of the quality of education teachers receive during their training.  相似文献   

‘I feel like I can do it now’: preservice teacher efficacy in a co-teaching community of practice     

Andrea M. Hawkman  Kathryn B. Chval  Laurie H. Kingsley 《Teaching Education》2019,30(1):86-104

Teacher efficacy, or teachers’ feelings about their abilities in the classroom, remains a major component of educational research. We know that despite participating in shared or similar experiences, some preservice teachers (PSTs) develop feelings of teacher efficacy and some do not. Yet, in-depth examinations into the specific practices of successful host schools are scarce in the deep field of teacher efficacy research. We examine the deliberate actions of one Midwestern elementary school to establish a climate and co-teaching process that deliberately seeks to foster PST success and feelings of confidence in the classroom. We also discuss implications for teacher education.  相似文献

The Effects of “Friend” Characteristics on Evaluations of an Activist Group in a Social Networking Context     

Qian Xu  Mike Schmierbach  Saraswathi Bellur  Erin Ash  Anne Oeldorf-Hirsch  Andrew Kegerise 《Mass Communication and Society》2013,16(3):432-453

Research suggests that individuals use cues about the popularity of a cause or group to make judgments. This bandwagon phenomenon has found particular support in online contexts. However, perceptions regarding the group may also depend on the identity of those supporters. We employed a 2 × 2 × 2 experiment to test the effect of number of affiliates and affiliate race and age on feelings toward the group, its page, and intended support. Results suggest that feelings are not subject to a consistent bandwagon effect but rather are moderated by race, with White participants exhibiting more positive feelings when seeing a page with few Black affiliates or many White affiliates. This result contrasts with findings for age, which serves to moderate only intended page use.  相似文献   

An exercise protocol that simulates the activity patterns of elite junior squash

Abstract

Squash is a popular racket sport that requires intermittent activity with frequent bursts of near maximal-intensity exercise. Consequently, effective physiological and thermoregulatory responses are important contributors to performance during squash match-play. Controlled field-based simulation protocols have been introduced in a growing number of sports, which allow sports scientists to investigate changes in physiology and the efficacy of various interventions in sport-specific contexts. This study aimed to develop an exercise protocol that simulates the physiological requirements of elite squash match-play. Eight elite junior squash players (age 16.2 ± 0.8 years, height 1.76 ± 0.06 m, body mass 61.3 ± 5.9 kg; mean ± s) completed the following in a randomized order: (1) a squash match against a player of similar standard and (2) a squash-specific incremental exercise protocol (multistage squash test [MST]) followed by the squash simulation protocol (SSP). The multistage squash test was continued for 18.0 ± 1.0 min and elicited near maximal post-MST heart rates, blood lactate concentrations and ratings of perceived exertion (198 ± 9 beats · min^?1, 5.7 ± 1.7 mmol · l^?1 and 18 ± 1, respectively). The SSP was 12.2 min in length compared with mean game length during competitive matches of 10.0 ± 1.6 min (P = 0.27). Peak heart rates were similar during the SSP and match-play (192 ± 11 and 189 ± 6 beats · min^?1, respectively; P = 0.44). Mean exercising heart rates were similar during the SSP (180 ± 8 beats · min^?1) and match-play (179 ± 13 beats · min^?1; P = 0.73). Peak blood lactate concentrations during the SSP and match-play were 3.5 ± 1.5 and 2.4 ± 1.2 mmol · l^?1 (P = 0.07), respectively. Peak ratings of perceived exertion during the SSP and match-play were similar (17 ± 2 and 17 ± 2, respectively; P = 0.64). It was concluded that the SSP closely replicated the demands of squash match-play in elite junior squash players. Furthermore, the SSP provides coaches and scientific support staff with a controlled squash-specific exercise protocol that has potential application in the objective investigation of a range of interventions such as training programmes, nutritional supplements and strategies to maintain core body temperature.  相似文献   

Knowing in action: Beyond communities of practice   总被引：2，自引：0，他引：2  

Ash Amin  Joanne Roberts 《Research Policy》2008,37(2):353-369

This paper engages with the recent turn in the social sciences towards communities of practice as a driver of learning and knowledge generation across a variety of different working environments. While agreeing with the broad reinstatement of situated social practice in thinking on the dynamics of knowledge capitalism, the paper takes issue with the increasingly homogeneous and instrumentalist use of the term communities of practice to encapsulate ‘knowing in action’. On the basis of an extensive review of the available literature, the paper argues for the importance of differentiating between different varieties of knowing in action. The paper notes the differences - in organisation, spatial dynamics, innovation outcomes, and knowledge processes - between four modes: craft or task-based knowing; epistemic or high creativity knowing; professional knowing; and virtual knowing. The proposed typology is used to illustrate the insight gained from such analytical precision, through a discussion of the spatial configuration of knowing in action, long assumed to require spatial proximity. It is shown that spatial and relational proximity - which can be struck at a distance - should not be treated as one and the same.  相似文献

How Families Use Questions at Dioramas: Ideas for Exhibit Design     

Doris Ash 《Curator: The Museum Journal》2004,47(1):84-100

This paper explores the role of questioning in scientific meaning‐making as families talk, look and gesture in front of realistic and artful dioramas at the Natural History Museum of Los Angeles County. The focus is on the ways questioning can either enable movement towards scientific understanding or hinder such progress. The socio‐cultural framework of this research emphasizes Vygotsky's interpretation of the zone of proximal development (zpd). Questions are viewed as tools for mediation in the zpd. This paper examines three families' dialogues, excerpted from a larger study of collaborative sense‐making among family groups in a natural history museum. It seeks to understand how collaborative dialogue meshes everyday understandings with canonical science, in this case through the use of questions.  相似文献
