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

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.     

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

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.     

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

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.     

A Critique of Educational Research

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.     

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

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.

Experiencing spiritual aspects outdoors in the winter: a case study from the Czech Republic using the method of systemic constellations

The article focuses on spirituality on two semantic levels: the first one analyses participants’ experiences during a winter expeditionary course on snowshoes and considers the question of whether residing in the winter landscape with a community of other people may acquire a spiritual dimension in spite of the non-religious environment. The second level verifies whether the trans-rational method of systemic constellations may be used as a research tool, that is, as a specific source for data collection (different from other sources and methods). The research applied a phenomenological approach to the analysis of unstructured interviews (n = 12) and constellation insights; the result confirmed indisputably that certain kinds of experiences obtained in a completely non-religious environment (namely, during a winter expedition on snowshoes in the mountains) can be considered spiritual. The answer to the second question is also positive, since the application of systemic constellations results in different data in comparison with their verbal acquisition. Symbolic images that point out the system and its unaccepted elements deepen the understanding of both the individual and the nature of their spiritual experience.
