This article explores the views of six higher education students with autism/Asperger syndrome. The research draws upon social identity theory to explore how participants made meaning of their label. There was consensus that information given at the point of diagnosis generally did not reflect their individual experiences. First‐hand accounts tended to be perceived as more personally relevant. The ‘Asperger’ identity was generally framed as fragile and inconsistent, leading some individuals to distance themselves from it. This may be problematic for a group that is already disadvantaged and isolated. However, participants conveyed strong self‐images regardless of how and whether they identified with their diagnosis, which was attributed to their relative privilege in achieving higher education and therefore experiencing success and achievement related to their personal strengths. In this article, Andrea MacLeod, Ann Lewis and Christopher Robertson, from the University of Birmingham, call for researchers and relevant services to involve autistic individuals directly in fostering a constructive ‘autism identity’.  相似文献

In this study an attempt was made to construct a multi-factor model predicting the development of reading literacy in the upper grades of primary school in the Netherlands for subgroups of 729 first language (L1) learners and 93 second language (L2) learners. Following a longitudinal design, it was explored to what extent the variation in reading literacy development in L1 and L2 from grade 4 to grade 6 can be explained from children’s word decoding, language, mathematics and nonverbal reasoning skills, reading motivation and self confidence as well as their home reading resources. The results showed that L1 and L2 learners differed in reading literacy skills, language, mathematics, and reasoning skills. Structural equation modelling showed that the reading literacy development in both L1 and L2 learners could be explained from decoding, language, mathematics and reasoning skills, as well as their motivation and self-confidence. A striking difference was the fact that home reading resources had an impact on reading literacy in L1 learners but not in L2 learners.  相似文献

Interdepartmental integration, the melding together of disparate functional areas within an organization, is believed to be associated with superior firm performance. However, the particular approach that human resource development practitioners should focus on to improve performance is not well‐understood. Our research assesses three alternative approaches to interdepartmental integration: the interaction, collaboration, and combination views. The interaction view suggests that successful interdepartmental integration is achieved primarily by increasing the volume of meetings and documented information exchange; the collaboration view prescribes teamwork, sharing, and the achievement of collective goals. The third view suggests that Successful integration involves a combination of interaction and collaboration. The results of a recent survey of functional managers are presented. The findings indicate that interaction and collaboration are both positively associated with performance and extendi previous empirical work by suggesting that, when viewed collectively, collaboration mediates the relationship between interaction and performance. Implications for practice and future research are discussed.  相似文献

Classroom Learning Environments and Students' Approaches to Learning   总被引:1,自引:0,他引:1  
Four hundred and eighty-four students from two metropolitan secondary schools completed the Learning Process Questionnaire, the Individualised Classroom Environment Questionnaire and the Learner Self Concept scale. Relationships between perceptions of the classroom learning environment, approaches to learning and self concept as a learner were investigated. Gender and level of schooling (junior high versus senior high) differences were examined. Results showed Deep Approaches to learning were significantly related to classroom learning environments which were perceived to be highly personalised and to be encouraging active participation in the learning process and the use of investigative skills in learning activities. High learner self concept was positively associated with Deep Approaches to learning and with classrooms perceived as high in Personalisation. It was negatively associated with Surface Approaches to learning. Differences in perceptions of learning environments and approaches to learning in relation to gender and level of schooling were small. The implications of these findings are discussed and strategies for facilitating Deep Approaches to learning are referred to. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

Performing arts organizations are characterized by different objectives other than revenue. Even if, on the one hand, theaters aim to increase revenue from box office as a consequence of the systematic reduction in public funds; on the other hand, they pursue the objective to increase its attendance. A common practice by theaters is to provide incentives to customers to discriminate among themselves according to their reservation price, offering a schedule of different prices corresponding to different seats in the venue. In this context, price and allocation of the theater seating area is decision variables that allow theater managers to manage their two conflicting goals to be pursued. In this paper, we introduce a multi-objective optimization model that jointly considers pricing and seat allocation. The framework proposed integrates a choice model estimated by multinomial logit model and the demand forecast, taking into account the impact of heterogeneity among customer categories in both choice and demand. The proposed model is validated with booking data referring to the Royal Danish theater during the period 2010–2015.  相似文献

Magnetic and inertial measurement units (MIMUs) may provide an accessible, three-dimensional, in-field alternative to laboratory-restricted marker-based motion capture. Existing upper limb MIMU models have predominantly been validated with low-velocity motion and their suitability for use with sport-based movements remains relatively untested. We propose a MIMU system approach to enable the estimation of anatomically meaningful and participant-specific elbow kinematics with considerations for use with cricket bowling. A novel standardised elbow reference posture of 90 degrees flexion and 0 deg pronation, and functional definition of elbow joint axes of rotation calibrated the MIMU method model before it was validated across three experiments: (1) simple elbow rotations with a mechanical linkage; (2) low-velocity elbow rotations in human participants; and (3) low-medium velocity sport-based movements in human participants. The proposed MIMU method demonstrated high elbow kinematic measurement agreement when compared with a criterion measure across all three conditions. However, during experiment 3, sensor components neared their measurement capacity and the MIMU method elbow flexion measurement variability increased. We conclude that the proposed MIMU method can estimate anatomically referenced, participant-specific joint angles, however, the hardware specifications of currently available systems may limit application in high-velocity/acceleration situations, preventing the measurement of cricket bowling in-field for now.  相似文献

Physiological characteristics of America's Cup sailors   总被引:2,自引:0,他引:2  
The aim of this study was to assess the physiological profile of America's Cup grinders and mastmen, by measuring energy expenditure during sailing and assessing their aerobic and anaerobic fitness. The study focused on estimating the energy used during grinding activity, by measuring oxygen uptake (VO(2)) during sail setting in real sailing conditions. In the laboratory, using an arm-cranking ergometer, we measured VO(2peak) during an incremental maximal exercise test and total energy expended during the effort and recovery phases of an all-out test that simulated grinding activity, in six grinders and mastmen and ten sailors of the same crew. Total energy used during grinding corresponded to 45% (s = 9) and 51% (s = 5) of that used in the all-out test (234 kJ, s = 21.7) for tacks and gybes, respectively. In both grinding activity and the all-out test, VO(2) increased during and after the effort. The "VO(2) top value" was 53% (s = 8.6), 68% (s = 5.5), and 78% (s = 3.1) of VO(2peak) (4.7 l . min(-1), s = 0.43) in tacks, gybes, and the all-out test, respectively. During fast sequences of grinding activity, the "VO(2) top value" reached 65% (s = 7.1) VO(2peak) in tacks and 91% (s = 3.3) VO(2peak) in gybes. Our results suggest that grinders and mastmen are characterized by a high anaerobic capacity but their performance can be improved by powering aerobic fitness, to increase this energy contribution to all-out efforts and to guarantee fast recovery when grinding activity is repeated with short rest intervals.  相似文献
