DVD sales and the R-rating puzzle

In the last decade, attendance at movie theaters has been relatively stagnant, while sales of digital versatile discs (DVDs) have grown dramatically. In this paper, we look at the factors determining sales of individual DVDs in the United States. Using data on new motion pictures released on DVD between 2006 and 2008, we find the demand for new DVDs is price-inelastic and that DVD sales are counter-cyclical. We find that previous box office success has strong positive effects on DVD sales. Production budget also has a positive effect on DVD sales, albeit indirectly through its effect on box office revenues. Critical acclaim has significant positive effects on both box office revenue and DVD sales, but the effect is smaller in regard to DVDs. There is some evidence to suggest that DVD sales are higher for movies with more sexual content and more violent content and lower for movies with more profanity, but these effects are indirect through the changes in the box office of these movies. We find that sales of R-rated DVDs are not as dependent upon critical acclaim as movies of other ratings, and are thus less risky for movie studios to produce. Our findings provide another explanation for the R-rating puzzle.     

The controversy over change.

The full impact of twentieth century technology upon medical libraries was first felt in the late 1950s and early 1960s with the introduction of electronic automation into library methodology. During those years, often the aura of technology for the sake of technology prevailed, and medical librarians did little to inform themselves of capabilities, potentialities, and limitations in relation to cost-effective library usage of automation. Likewise, currently microforms and audiovisuals are frequently acquired for their own sake instead of for their capacity to transmit messages in the most effective and comprehensive way possible. Controversy has raged and still rages over the pros and cons of applying modern technology to library procedures and over the coexistence of the printed page with electronic media. New systems and methodologies, machine or manual, must realistically be evaluated in terms of increased service output by the library to its clientele. Regardless of technological sophistication, any machine that does not significantly contribute to that specific aim has no place in a library. The tradition of the medical librarian has always been to collect, organize, store, and disseminate information in the most efficient manner that the media of the times have had to offer.     

How to Choose the Best

This chapter deals with a crucial component of our position, the presumption that there are objective grounds for preferring one thing to another within the various cultural institutions we deal with, that there are better or worse symphonies, soufflés and theories of the atom. The task of showing this is more urgent for some institutions than others. While philosophers can doubt anything, most people are persuaded of the objectivity of our efforts to comprehend the physical world and to weigh, count and measure accurately in many areas of human activity. Again, when we are faced with a choice among functional objects or processes, most people will admit that we can ground a preference for a knife or an exercise routine on objectively established facts: sharpness, or measurable increase in strength. Here, certainly, various conflicting desiderata may enter and make actual decisions more difficult — the sharpest knife may also be the most expensive; we may need to worry about its safety features; it may be ugly; and so on. But many will doubt that our judgements of comparative worth for non-functional objects such as paintings or sonatas can claim a similarly objective basis. We shall, therefore, concentrate our efforts on the most doubted areas, but will begin with the less contentious, where we think it is useful to draw attention to the genuine problems some philosophers have stressed, to show in fact that what we believe to be popular unconcern deserves to be somewhat ruffled.     

How Not to Think About High Culture — A Rag-Bag of Examples

Defenders of high culture can be found invoking many and various allies. Many are, we think, out of place. These defences raise issues that we do not need to worry about or themselves create unnecessary difficulties for clarity of thought on these matters. In this chapter we will touch upon a number of such irrelevancies. We will begin by examining the assimilation of high culture to religion and religious concerns in the thought of Eliot and Scruton: this will allow us to indicate our stance on the place of religion in schools. We will then examine some psychological and sociological issues that Bantock has invoked in defending his secular vision of the role of culture, and conclude with Barrow's curious identification of culture with general intelligence.     

External load training does not alter balance performance in well-trained women

This study investigated the influence of external load training (ELT) on static and dynamic balance. Nineteen females stratified into two groups (ELT = 9, control = 10) completed three testing sessions over 6 weeks. The ELT group wore weighted vests (WV) of ~8% body mass for 32 h/week during daily living and three training sessions/week for 3 weeks. Following completion of ELT, a 3 week detraining (DET) phase was completed. Bilateral and unilateral static balance were assessed with eyes open and closed. Dynamic balance was assessed using the star excursion balance test (SEBT). Static and dynamic balance variables were analysed using a 2 (group) x 3 (time) between participants repeated measures ANOVA (p < 0.05). Results revealed significant reductions in average centre of pressure (COP) velocity in the control group on the non-dominant limb with eyes closed, and significantly greater reach distances in the ELT group on the SEBT for the posteromedial and medial directions on the dominant limb (p < 0.05). These findings suggest the ELT group did not significantly improve their balance in comparison to the control group. However, future research should further examine this unique, supplemental training method and the impact on balance performance.
