Analysing the effect of digital technology on channel strategy, power and disintermediation in the home video market : the demise of the video store?

The antecedents of channel power (e.g. El-Ansary and Stern, 1972) and the impact of channel structure ( e.g. Anderson and Narus,1984) on channel dynamics have long been important topics within the channel literature. In addition to the theoretical and methodological contributions, research in these areas has helped channel managers to understand how power is generated and used in coordinating distribution strategies in different contexts. The study presented in this paper builds upon these previous literatures, which are first briefly reviewed below.

A survey on the relationship between trust and interest similarity in online social networks

A remarkable growth in quantity and popularity of online social networks has been observed in recent years. There is a good number of online social networks exists which have over 100 million registered users. Many of these popular social networks offer automated recommendations to their users. This automated recommendations are normally generated using collaborative filtering systems based on the past ratings or opinions of the similar users. Alternatively, trust among the users in the network also can be used to find the neighbors while making recommendations. To obtain the optimum result, there must be a positive correlation exists between trust and interest similarity. Though the positive relations between trust and interest similarity are assumed and adopted by many researchers; no survey work on real life people’s opinion to support this hypothesis is found. In this paper, we have reviewed the state-of-the-art research work on trust in online social networks and have presented the result of the survey on the relationship between trust and interest similarity. Our result supports the assumed hypothesis of positive relationship between the trust and interest similarity of the users.

Resistance is hopeless : assimilating queer theory

This paper seeks to assimilate Queer Theory: that is, to bring it within the gambit of a ‘mainstream’ or ‘dominant’ space: the academy. It does so by historicising Queer Theory, and investigating, if not what it is, then at least what it has been. This makes it possible to engage critically with Queer Theory. Suggesting that Queer Theory has often employed tropes of assimilation, the paper turns to another cultural site at which such language is popular - science fiction - in order to investigate the assumption of these metaphors. It goes on to suggest some of the assumptions about cultures which underlie these metaphors. Finally, it points to other sites in Queer Theory which undermines these assumptions, and provide other ways - quite uninterested in assimilation - in which to think Queer.

Indigenous knowledges : informing and supporting Indigenous students during their first year at university

This paper critically examines dominant discourses informing First Year Experience programs delivered for Aboriginal and Torres Strait Islander students participating in higher education. We interrogate traditional ‘deficit models’ through the recognition and acknowledgement of Indigenous knowledge at the cultural interface, the arena in which Aboriginal and Torres Strait Islander students encounter university for the first time. In this paper, we demonstrate how the First Year Experience programs for Indigenous students, developed and delivered by the Oodgeroo Unit, are conceptualised by Indigenous knowledges. By recognising Indigenous knowledges and experiences, and valuing these within the Western academy, we provide an alternative to these dominant mainstream discourses and perspectives for Indigenous students navigating their way through university. We argue that Indigenous standpoints provide tools through which Indigenous students can negotiate the cultural interface that exists within the university environment.

Rodent blood-stage Plasmodium survive in dendritic cells that infect naive mice.

Plasmodium spp. parasites cause malaria in 300 to 500 million individuals each year. Disease occurs during the blood-stage of the parasite’s life cycle, where the parasite is thought to replicate exclusively within erythrocytes. Infected individuals can also suffer relapses after several years, from Plasmodium vivax and Plasmodium ovale surviving in hepatocytes. Plasmodium falciparum and Plasmodium malariae can also persist after the original bout of infection has apparently cleared in the blood, suggesting that host cells other than erythrocytes (but not hepatocytes) may harbor these blood-stage parasites, thereby assisting their escape from host immunity. Using blood stage transgenic Plasmodium berghei-expressing GFP (PbGFP) to track parasites in host cells, we found that the parasite had a tropism for CD317+ dendritic cells. Other studies using confocal microscopy, in vitro cultures, and cell transfer studies showed that blood-stage parasites could infect, survive, and replicate within CD317+ dendritic cells, and that small numbers of these cells released parasites infectious for erythrocytes in vivo. These data have identified a unique survival strategy for blood-stage Plasmodium, which has significant implications for understanding the escape of Plasmodium spp. from immune-surveillance and for vaccine development.

Is Dawkins a modern-day Nicodemus?

This article applies a Wittgensteinian approach to the examination of the intelligibility of religious belief, in the wake of the recent attack on the Judeo-Christian religion by Richard Dawkins's book The God Delusion. The article attempts to show that Dawkins has confused religion with superstition, and that while Dawkins's arguments are decisive in the case of superstition, they do not successfully show religion to be a delusion. Religious belief in God is not like belief in the existence of a planet, and genuine religious faith is not like the belief in something for which there is not yet enough evidence, like belief in dark matter. The Christian doctrines of the resurrection and eternal life are misconstrued if they are understood as factual claims because they are then merely shallow superstitions, and not the great religious riddles they are meant to be.

How do our 'quicks' generate pace? A cross sectional analysis of the Cricket Australia pace pathway

Technique and physical contributions to ball delivery speed in fast bowling have been popular research topics in sports science. However, a common limiting factor of this work is the level of expertise of participants and lack of within bowler investigations (Salter et al., 2007). The relationship between technique, anthropometry and ball speed has not been comprehensively investigated among elite fast bowlers. The purpose of this study was to examine the relationship between technique, anthropometric variables and ball speed using both within- and betweenbowler analyses in a cross section of the Cricket Australia high performance pace pathway.

What the experts think : fast bowling expertise acquisition and talent development

For applied sport scientists charged with developing talented performers an essential requirement is to identify components contributing to the development and maintenance of expertise. Previous qualitative analysis has revealed several psychological (e.g., mental focus, goal-setting and selfevaluation), socio-cultural (e.g. community and family support, cultural influence), physical (e.g., strength, height) and environmental (e.g., access to facilities and climate) constraints on successful Olympian development (Abbott et al., 2005). Open-ended interviews with expert athletes and/or expert coaches have been used to reveal competencies of elite performers to derive factors associated with success (Durand-Bush et al., 2002). However, the influence of these factors is likely to be sport-specific due to different task constraints and the changing nature of the performer-environment relationship through practice, coaching and competing (Vaeyens et al., 2008). So far, only one study on expertise acquisition in cricket has been undertaken. Weissensteiner, et al. (2009) found that development of expertise in cricket batting in Australia may be facilitated by early unstructured play (i.e. ‘backyard cricket’), a wide range of sport experience during development, and early exposure to playing with seniors.
