This paper explores the implications of thedevelopment and extension of national andinternational intellectual property regimes (IPRs) forthe liberal university. It argues that dynamics setinto motion by IPRs are eroding the university'sability to reproduce itself in two ways. On the onehand, IPRs are reducing the university's ability todraw on and to replenish the intellectual commonswhich is one fundamental precondition of its survival.IPRs are also preventing academics from fulfillingtheir public service mission which may undermine thepopular support for the university that is alsocrucial to its survival. These two mutuallyreinforcing developments are making it increasinglydifficult for the liberal university to continue on asit has. Indeed, they are producing a qualitativetransformation of the institution that will be verycostly to society, in both economic and social terms.The paper argues that although current developmentspose very serious threats to the liberal university'sfuture, there is still time to intervene in order topreempt or to alter them. The paper concludes with adiscussion of strategies that may enable the liberaluniversity to survive, if not flourish, in the currentcontext. In particular, a strategy of pursuing broadIP exemptions for universities isadvocated. 相似文献

Up to now, very few studies investigated the influence of gender on the depiction of emotions in children’s drawings. However, the literature on emotions reveals differences between boys and girls in various kinds of tasks (e.g. recognising emotional facial expressions, understanding an emotional situation, etc.). Therefore, we examined the impact of gender on the depiction of sadness and anger. We took into account children’s gender but also the gender of the character expressing the target emotion. Forty-four boys and forty-seven girls aged 7–8 and thirty-six boys and fifty-three girls aged 9–10 were asked to listen to stories where the main character (either a male or a female) was feeling sad or angry and then to draw the facial cues corresponding to the target emotion. Two methods were used to rate the drawings: judges assessed the correct vs. incorrect depiction of the two target emotions and a content analysis was then conducted on the correct drawings so as to reveal the type of facial cues used by children. By showing the major influence of children’s gender on their depiction of sadness and anger, our findings offer promising lines of research in educational and clinical settings. 相似文献

The strongest tradition of IR systems evaluation has focused on system effectiveness; more recently, there has been a growing interest in evaluation of Interactive IR systems, balancing system and user-oriented evaluation criteria. In this paper we shift the focus to considering how IR systems, and particularly digital libraries, can be evaluated to assess (and improve) their fit with users’ broader work activities. Taking this focus, we answer a different set of evaluation questions that reveal more about the design of interfaces, user–system interactions and how systems may be deployed in the information working context. The planning and conduct of such evaluation studies share some features with the established methods for conducting IR evaluation studies, but come with a shift in emphasis; for example, a greater range of ethical considerations may be pertinent. We present the PRET A Rapporter framework for structuring user-centred evaluation studies and illustrate its application to three evaluation studies of digital library systems. 相似文献

Previous nationally-representative research in Scotland found a j-shaped relationship between age and leisure sedentary time (ST): a decrease from young to middle-age, before rising steeply in older-age. This study investigated the effects of age and sex on weekday (including work) ST for all adults and stratified by work-status, and on weekend day ST. Differences in the relative contributions of component behaviours were also investigated. Responses from 14,367 adult (≥16 years) 2012–14 Scottish Health Survey participants were analysed using linear regressions. We found no j-shaped relationship between age and weekday ST. Instead, only 16–24 year olds reported lower levels than those over 75 years (6.6 (95% CI: 6.3–6.9) compared to 7.4 (95% CI: 7.2–7.6) hours/day; p < 0001). The j-shape was only evident in the stratified analysis amongst women not in work, and for weekend day ST for all groups. For those in work, work ST accounted for 45% of weekday ST. Television/screen ST made up over half of leisure ST on weekdays and weekend days, regardless of sex, age, or work-status. These results challenge our understanding of how ST varies by age. Interventions to reduce ST should consider differences in the relative contributions of ST behaviours by age and work-status. 相似文献
