An Investigation of Value-, Impression-, and Outcome-Relevant Involvement on Attitudes,Purchase Intentions,and Information Seeking     

Brian L. Quick  Sarah N. Heiss 《Communication Studies》2013,64(3):253-267

This investigation explored the relationship between value-relevant (VRI), impression-relevant (IRI), and outcome-relevant involvement (ORI) on information-seeking behaviors, attitudes, and purchase intentions. Results revealed that grocery shoppers' (N = 175) ORI was positively associated with information-seeking behaviors, attitudes, and purchase intentions of foods high in fiber. Neither VRI nor IRI predicted attitudes or purchase intentions. Results are discussed with an emphasis on information seeking among the three types of involvement and message-design strategies with respect to promoting foods high in fiber.  相似文献   

(7) Need for a Municipal Library System for the City of Calcutta     

P. B. Roy  P. Raychaudhury 《International Information and Library Review》2013,45(1):43-49

Abstract

A study of the development of third generation Nigerian university libraries established between 1980-1984 was conducted during the latter part of the 1990/91 session. The study, which was carried out through the use of a questionnaire, personal visits, as well as informal discussions with the staff, had the objective of determining the similarities and dissimilarities in the growth of the libraries using indices such as governance, finance, stock and services, etc., as well as problems affecting their effective performance. The outcome of the study showed that there are more areas of similarities than dissimilarities in the ways they operate. Poor funding, scarcity of foreign exchange for the purchase of library materials from abroad, near absence of modern information retrieval technologies as well as theft and mutilation of materials, were found to constitute major problems to their rapid development. The recently negotiated World Bank loan for the Nigerian university sector designed to inject some US$120m for the purchase of books, journals and library equipment among others gives a ray of hope, though on a short-term basis. It is suggested that to take the university libraries out of the woods, massive injection of funds on a long-term basis is required.  相似文献   

Science and medicine of rowing: A review     

Roy J. Shephard 《Journal of sports sciences》2013,31(7):603-620

The biology and medicine of rowing are briefly reviewed. Effort in a 2000 -m race is about 70% aerobic. Because the boat (and in some instances a cox) must be propelled, successful competitors are very tall, with a large lean mass and aerobic power. Large hearts may lead to erroneous diagnoses of a cardiomyopathy. Large respiratory minute volumes must be developed by chest muscles that are also involved in rowing. The vital capacity is typically large, and breathing becomes entrained. Expiration cannot be slowed relative to inspiration (as normally occurs at high rates of ventilation) and the limiting flow velocity may be reached, with the potential for airway collapse. Performance is strongly related to the power output at the ‘anaerobic threshold’, and lactate measures provide a guide to an appropriate intensity of endurance training. Peak blood lactate levels are higher in males (commonly 11–19 mmol·l -1 and occasionally as high as 25 mmol·l -1) than in females (9–11 mmol·l -1), probably because males have a greater muscle mass in relation to blood volume. The skeletal muscles are predominantly slow twitch in type, developing an unusual force and power at low contraction velocities. Many rowers have a suboptimal diet, eating excessive amounts of fat. Lightweight rowers also have problems of weight cycling. Aerobic power and muscle endurance often change by 10% over the season, but such fluctuations can be largely avoided by a well-designed winter training programme. Injuries include back and knee problems, tenosynovitis of the wrist and, since the introduction of large blades, fractures of the costae.  相似文献   

Biology and medicine of soccer: An update     

Roy J. Shephard 《Journal of sports sciences》2013,31(10):757-786

Recent literature on the biology and medicine of soccer (primarily since 1990) has been accumulated by a combination of computer searching of relevant databases and review of the author's extensive files. From a total of 9681 papers, 540 were selected for closer scrutiny and 370 are discussed in the present review. These articles cover patterns of play and the resulting energy demands, the nutritional requirements of soccer, the anthropometric, physiological, biochemical and immunological characteristics of successful players, the influence of environmental stressors (heat, cold, hypoxia and time zone shifts), special features of female and junior competitors, selected issues in training, and the incidence and prevention of injuries. The information presented has important implications for the safety and success of soccer players; the challenge is now to ensure that this information is understood and acted upon by coaches and individual team members.  相似文献   

Prevalence of disordered eating in elite female athletes in team sports in Greece     

《European Journal of Sport Science》2013,13(9):1267-1275

ABSTRACT

The purpose of the study was to assess (a) the prevalence of disordered eating (DE) in elite female team sports players compared to non-athletes and (b) to compare DE prevalence in elite female players in basketball, volleyball and water polo. One hundred and seventy-five females were recruited (age 23.10?±?5.4, BMI 21.85?±?2.3?kg/m²), 53 were elite basketball players, 42 were elite volleyball players, 34 were elite water polo players and 46 were non-athletes. Participants completed the Eating Disorders Questionnaire (EDE-Q) and a physical activity questionnaire. The EDE-Q incorporates 36 statements which relate to the occurrence and frequency of key behaviours of eating disorders, under the following four subscales: Restraint, eating concern, shape concern and weight concern and a global score of disordered eating. No differences were found in the EDE-Q subscale score and global score between athletes and non-athletes. Only 6.2% of the total number of participants exhibited DE using the global score >2.3. Water polo players had significantly higher scores in the ‘eating concern’ subscale and in the frequency of key behavioural features of DE such as binge eating episodes and objective and subjective bulimic episodes, compared to volleyball and basketball players. In conclusion, team sport elite female players do not exhibit greater prevalence of DE compared to non-athletes. Water polo, a sport that emphasises leanness and control of body weight for international distinctions, is associated with a higher tendency to exhibit DE, when compared to other team sports.  相似文献
