The relationships among consumers’ ethical ideology,risk aversion and ethically-based distrust of online retailers and the moderating role of consumers’ need for personal interaction     

Isabel P. Riquelme  Sergio Román 《Ethics and Information Technology》2014,16(2):135-155

Consumer distrust is only recently beginning to be perceived as an important e-commerce issue and, unlike online trust, the nature and role of distrust is much less established. This study examines the influence of two important consumer characteristics (ethical ideology and risk aversion) on consumer’s ethically-based distrust of online retailers. Also, the moderating role of consumer’s need for personal contact with sales staff is tested. Results from 409 online consumers confirm that both relativist-based ethical ideology and risk aversion are strongly and positively related to consumers’ distrust. Interestingly, our findings show that positive effects of relativism and risk aversion on consumer’s distrust are moderated by consumers’ need for personal interaction, which is more pronounced for those consumers with a high need for personal interaction with retail salespeople.  相似文献   

Epidemiology of injuries in First Division Spanish football     

Javier Noya Salces  Pedro M. Gómez-Carmona  Diego Moliner-Urdiales  Manuel Sillero-Quintana 《Journal of sports sciences》2014,32(13):1263-1270

Abstract

The aim was to examine the injuries sustained by Spanish football players in the First Division and to compare injury-related variables in the context of both competition and training. The injury data were prospectively collected from 16 teams (427 players) using a specific web-based survey during the 2008/2009 season. A total of 1293 injuries were identified (145 were recurring injuries). The overall injury incidence was 5.65 injuries per 1000 h of exposure. Injuries were much more common during competition than during training (43.53 vs. 3.55 injuries per 1000 h of exposure, P < 0.05). Most of the injuries (89.6%) involved the lower extremities, and overuse (65.7%) was the main cause. Muscle and tendon injuries were the most common types of injury (53.8%) among the players. The incidence of training injuries was greater during the pre-season and tended to decrease throughout the season, while the incidence of competition injuries increased throughout the season (all P < 0.05). In conclusion, the results of this study suggest the need for injury prevention protocols in the First Division of the Spanish Football League to reduce the number of overuse injuries in the muscles and tendons in the lower extremities. In addition, special attention should be paid during the pre-season and the competitive phase II (the last four months of the season) in order to prevent training and competition injuries, respectively.  相似文献   

Return to play management after concussion in football: recommendations for team physicians     

Nina Feddermann-Demont  Dominik Straumann  Jiří Dvořák 《Journal of sports sciences》2014,32(13):1217-1228

Abstract

A concussion is a rare but potentially serious injury of football players. Thus, an immediate and valid diagnosis, estimate of severity and therapeutic management is required. To summarise the published information on management of concussion with respect to a safe return to play (RTP), a literature search was conducted. Current guidelines on concussion in sports and significant studies on concussion in football were analysed. After concussion, management and RTP decision should remain in the area of clinical judgement on an individualised basis according to the current international guidelines. If a concussion is suspected, the player should not be allowed to RTP the same day. The RTP programme should follow a gradual step-wise procedure. A concussed player should not RTP unless he/she is asymptomatic and the neurological and neuropsychological examinations are normal. Untimely RTP bears an increased risk of sustaining another more severe brain injury and repetitive brain injury of long-term sequelae. In football, the management of concussion should primarily follow the recommendations proposed by the Concussion in Sports Group. Information and education of players and their medical and coaching team help to protect the players’ health. Future studies on concussion should include validated and detailed information on RTP protocols.  相似文献   

Healthy Competition? The Public Interest in International Radiotelegraphy, 1919–1940     

Rita Zajácz Ph.D. 《广播与电子媒介杂志》2013,57(4):652-667

This article traces the definition of the public interest from the Navy Department through the FRC, to the FCC, with regard to the right mixture of competition and monopoly in international radiotelegraphy and identifies foreign policy as an important policy area where regulatory autonomy is enhanced. Policymakers defined the public interest independently of industry pressure because of internal divisions in the industry and, more importantly, because the strategic and international dimensions of the policy area brought the Navy Department into the regulatory mix and prompted the Commission to adopt a realist, rather than a liberal, framework.  相似文献   

The effects of inter-letter spacing in visual-word recognition: Evidence with young normal readers and developmental dyslexics     

Manuel Perea  Victoria Panadero  Carmen Moret-Tatay  Pablo Gómez 《Learning and Instruction》2012,22(6):420-430

Recent research has demonstrated that slight increases of inter-letter spacing have a positive impact on skilled readers' recognition of visually presented words. In the present study, we examined whether this effect generalises to young normal readers and readers with developmental dyslexia, and whether increased inter-letter spacing affects the reading times and comprehension of a short text. To that end, we conducted a series of lexical decision and continuous reading experiments in which words were presented with the default settings or with a small increase in inter-letter spacing. Increased spacing produced shorter word identification times not only with adult skilled readers (Experiment 1), but also with young normal readers (Grade 2 and Grade 4 children; Experiment 2) and, even to a larger degree, with readers with dyslexia (Experiments 3 and 4). These experiments suggest that slight increases in inter-letter spacing would improve the readability of texts aimed at children, especially those with dyslexia.  相似文献   

A Critique of Educational Research     

Pádraig Hogan 《牛津教育评论》2013,39(2):141-155

Abstract

Instrumentalist theories are older than liberal, reconstructionist or child‐centred ones and the concept of progress they embody seems very obvious at first sight: making schools and other educational institutions more relevant to social needs. In open market societies however social needs are even more fiercely contested than are intrinsic educational values or the needs of individual childen. When a social need is politically legitimated in newly closed societies, even resolute instrumentalists may blanch at what is required of schools, as Durkheim's disciples found in occupied France. In contemporary English‐speaking societies the paradox is noted that neo‐Marxists consider educational institutions to be instruments in the hands of the ‘ruling classes’ and to be part of an Ideological State Apparatus (ISA), whereas all those who may be defined as members of such ruling classes bemoan that these institutions are dysfunctional to the needs of industry and commerce and hostile to market societies.  相似文献   

Multimedia in modern language teacher education     

Manuel Jiménez Raya 《Educational Media International》2013,50(3-4):305-317

This paper discusses the professional development of primary modern language teachers through the use of new technologies. It explores the principles upon which the development of a multimedia learning environment (FLiP – Foreign Languages in Primary) was constructed. These entail principles of effective modern‐language teaching, principles of teacher education, and a conception of the effective teacher. In addition, ways in which technology can support the principles of effective professional development are discussed. Information technology can be extremely empowering, extremely motivating and extremely conducive to creating new and exciting teacher‐education environments. The most outstanding contribution is that multimedia environments can make teachers look beyond the immediate context thanks to the incorporation of indirect observation.Les multimédias dans la formation des enseignants en langues étrangères. Cet article discute le d´eveloppement professionnel des enseignants du primaire en langues modernes, grâce à l'utilisation des nouvelles technologies. Il explore les principes selon lesquels le développement d'un environnement multimédia a été construit (FLIP - Foreign Languages in Primary). Ils impliquent les principes de l'enseignement efficace des langues modernes, les principes de la formation des maîtres, et une conception du maître efficace. De plus, les façons dont la technologie vont soutenir les principes d'un développement efficace sont discutées. La technologie de l'information peut être très puissante, très motivante pour créer des nouveaux environnements excitants pour la formation des maîtres. La plus importante contribution est que les environnement mulitimédia amènent les maîtres à regarder au delà du contexte immédiat grâce à l'incorporation de l'observation indirecte.Multimedia in der Ausbildung von Lehrern für neue Sprachen. Dieses Papier erörtert die professionelle Entwicklung von Material zur Ausbildung von Grundstufenlehrern für moderne Sprachen durch die Verwendung neuer Technologien. Es vermittelt die Prinzipien, auf denen die Entwicklung einer Multimedia Lernumgebung ('FLIP - Foreign Languages in Primary') aufgebaut wurde. Diese enthalten Prinzipien modernen Sprachunterrichts, Prinzipien von Lehrerbildung und ein Konzept des 'wirksamen' Lehrers.

Universities,the Information Technology Challenge,and Open and Distance Learning in Central and Eastern Europe     

Tamás Lajos  András SzÛcs 《Higher Education in Europe》1998,23(2):177-185

The educational needs of eastern and central Europe can be met by distance education methods. The need to reform and to expand open and distance education possibilities led in 1990 to the founding in Budapest of EDEN, the European Distance Education Network. After 1990, the proponents of open and distance education were able to expand the scope of their activities as the result of expanding possibilities provided by the rapidly developing information and communication technologies. The pedagogical possibilities offered by these technologies are described with an emphasis on their democratizing tendencies, their ultimate inexpensiveness in terms of the total costs of different types of higher education, and their commercial possibilities. The setting up of the Distance Education Centre of the Technical University of Budapest is presented as a case study. Governments and institutions must find the best ways to use the information and communication technologies to integrate traditional higher education with open and distance learning techniques so as to offer the best possibilities at regional, national, and institutional levels.  相似文献
