Recreational angling tournaments: participants' expenditures     

John Curtis  Stephen Hynes  Paul O'Reilly  Benjamin Breen 《Journal of Sport Tourism》2017,21(3):201-221

Fishing tournaments are a common feature in recreational angling across a wide range of target species in both fresh and salt waters. Tournaments are organised for a number of purposes, including as commercial enterprises; as fund-raising initiatives for angling clubs; for economic development purposes (e.g. tourism); as well as improve participants' skill levels. Most tournaments are confined to geographically small areas and usually occur over a small number of days, which can mean a pulse of economically significant activity in the local area. This paper analyses the nature of expenditure associated with angling tournaments, including travel, food and accommodation, and angling-related expenditures as a function of socio-economic and angler characteristics. Analysis based on 106 tournaments across Ireland during 2013 finds a clear 80/20 segmentation between ‘high’- and ‘low’-spend anglers and that the segmentation occurs across all fish target species considered. The analysis also finds that British coarse anglers participating at Irish angling tournaments spend considerably more than other anglers irrespective of target species or angler country of origin.  相似文献

Preferences of students with learning disabilities for alternative service delivery modes     

Susana Padeliadu 《欧洲特需教育杂志》2013,28(3):210-226

ABSTRACT

This study investigates the preferences of students with learning disabilities regarding the location in which they receive help and the person from whom to get help. The attitudes of students with learning disabilities towards school as a function of the time they spend in the mainstream and their characteristics were also investigated. Results of the structured interviews and survey statements of 150 students indicated that they preferred receiving extra help in the special education class from the special education teacher. Students’ preferences for setting or teacher were not related to age, sex, IQ or academic achievement level, nor to the time students spent in the mainstream. The students expressed a positive attitude towards school in general, and towards their teachers, their classmates and the schoolwork in particular.  相似文献   

Cultivation of taste and bounded rationality: Some computer simulations   总被引：2，自引：2，他引：0  

Roger A. McCain 《Journal of Cultural Economics》1995,19(1):1-15

One can approach the economics of the arts, as any field of applied economics, in either of two ways. First, one can treat economic theory and econometric technique as subjects settled by specialists in those fields, to be used in the ec onomics of the arts as they are given, very much as if one were studying the demand for maize. Alternatively, one can treat the economics of the arts as a field which may need and suggest its own developments in theory and technique, suitable to its spec ial problems and processes, from which general economic theory and econometric theory might in principle learn something. Perhaps this latter view is implausible, given the high state of development of economic theory and econometrics in the modern liter ature. Yet many of the advances embodied in these fields have come from particular areas of application-and the economics of maize has been a particularly fertile field.I am indebted to participants in the Seventh International Conference on Cultural Economics, Fort Worth, Texas, October 1992; to p articipants in the Seminar on the Economics of the Arts, Venice, Italy, December 1992; to participants in the conference of the Pennsylvania Economists' Association, Wiles-Barre, PA, June, 1993; to participants in the second conference on Simulating Soci eties, Siena, Italy, July 1993; to participants in the conference of the Society for the Advancement of Behavioral Economics, Rensselaerville, NY, August 1993; and to participants in the Third Conference on Artificial Intelligence in Economics and Manage ment, Portland, OR, August 1993, for useful comments on topics related to the research reported in this paper.

What and how teacher educators prefer to learn     

Jurriën Dengerink  Mieke Lunenberg  Quinta Kools 《师资教育杂志》2015,41(1):78-96

In which areas and domains do individual teacher educators prefer to work on their professional development? What kind of learning activities do they want to take on and with whom? Are there significant differences in these preferences between teacher educators? This article reports on a recent survey (N = 268) about the professional development of teacher educators and differences in learning preferences between less and more experienced teacher educators and between university-based and school-based teacher educators. Findings show, for example, that while most university-based teacher educators were mainly interested in improving their teaching, less experienced school-based teacher educators were more focussed on aspects such as coaching skills. In this study, ‘learning profiles’ have been developed for four categories of teacher educators. These profiles may help to create more meaningful arrangements for teacher educators’ initial education and further professional development in a context where teacher education is required to have a more school-based as well as a more research-based orientation.  相似文献   

How stable is the stratification of higher education in England and Scotland?     

David Raffe  Linda Croxford 《British Journal of Sociology of Education》2015,36(2):313-335

This paper asks whether the institutional hierarchies defined by ‘golden triangle’, other Russell Group, other pre-1992 and post-1992 universities in England, and by ancient, old and new universities in Scotland, have become weaker since the 1990s. Using indicators constructed from Universities and Colleges Admissions Service data for 1996–2010, the article finds a stable hierarchical relationship among the sectors within each country, with some indicators showing a slight widening of status differences between sectors towards the end of the period. The main exception was a slight ‘upgrading’ of new (post-1992) universities in Scotland early in the period. There was little change in the association of institutional sector with social class, but in England the association with private secondary schools became slightly stronger and the association with ethnicity weakened.  相似文献   

Development of the Preferences for College Counseling Inventory     

Gregory T. Hatchett 《Journal of College Counseling》2015,18(1):37-48

This study describes the development of the Preferences for College Counseling Inventory (PCCI). In addition to providing data about college students' preferences for the logistics of counseling and the demographic/professional background of a potential therapist, the PCCI also provides numerical scores on 3 scales (Therapist Expertise, Therapist Warmth, and Therapist Directiveness) that measure preferences for therapist dispositions and 2 scales (Task‐Oriented Activities and Experiential/Insight‐Oriented Activities) that measure preferences for counseling activities.  相似文献
