Children's television: the soft underbelly of public service broadcasting

The provision of children's content should be a key constituent of the public service brand, but has often been viewed as a programme category at risk. Certainly in many countries children's television has moved from the 'scarcity' associated with terrestrial provision, to the 'plenty' of digital (see Ellis 2000). However in spite of a range of dedicated public service children's channels in Europe (CBeebies, Kika, Z@ppelin), domestically produced children's television in Europe is notoriously under-resourced if not marginalised. There is a pronounced reliance on imports (particularly on commercial television) notwithstanding the launch by US-owned multinationals (Disney, Nickelodeon, Cartoon Network) of localised versions of their children's television channels in many European countries. Within the broader context of global developments in children's media, this paper starts by outlining the recent and rapid crisis in British children's television and the factors that caused it. This was a crisis, which caught broadcasters and producers by surprise in the middle of 2006, but reflects many of the challenges faced by the children's television sector in other countries. It clearly demonstrated how a combination of the lack of regulatory protection, a change in commercial priorities among broadcasters, advertising restrictions, budgetary pressures and the competitive environment at home and abroad all combined to reinforce the trend towards a contraction of domestic production. The crisis also served to underline the dominance of the BBC - both as a representative of public service principles, and as the dominant producer and commissioner in the market. With the reasons underpinning the crisis explained, the paper will then analyse how the children's television community responded to the crisis and with what effect. Based on interviews, contemporary accounts and documentary evidence the paper will chart the converging and diverging views of broadcasters, producers, regulatory authority Ofcom, and a range of advocacy groups which represent children's interests and the industry. What arguments were elaborated in favour of protecting children's television as an integral part of the public service media brand? Can lessons be learned about how best to ensure the origination of children's media within a public service environment? Can developments in the UK be used to provide insight into how children's media might develop further?

Hierarchical structures: conducive or barrier to knowledge management?

This study examines managers‟ perceptions of Knowledge Management (KM) prior to implementation of KM-systems in a global insurance company and investigates whether Hierarchical structures are conducive to KM. Mixed methods are used, combining large scale surveying and case study using content analysis to organize the data into themes that provide the basis for arguments. Evidence suggests that managers strongly align their perception of KM with communication. Despite a multi-layered, hierarchical structure and strong middle management presence, organizational structure was not viewed as an issue. These factors are usually barriers to communication and organizational flexibility, yet managers believe that they may not inhibit KM becoming fully embedded. This evidence is contradicted by the results of a global KM study where silos, stovepipe and hierarchical structures were commonly cited as barriers. This contributes to the understanding of managerial mis-conceptions of knowledge as opposed to communication, and how organizations effectively share knowledge.

Why is “blindsight” blind? A new perspective on primary visual cortex, recurrent activity and visual awareness

The neuropsychological phenomenon of blindsight has been taken to suggest that the primary visual cortex (V1) plays a unique role in visual awareness, and that extrastriate activation needs to be fed back to V1 in order for the content of that activation to be consciously perceived. The aim of this review is to evaluate this theoretical framework and to revisit its key tenets. Firstly, is blindsight truly a dissociation of awareness and visual detection? Secondly, is there sufficient evidence to rule out the possibility that the loss of awareness resulting from a V1 lesion simply reflects reduced extrastriate responsiveness, rather than a unique role of V1 in conscious experience? Evaluation of these arguments and the empirical evidence leads to the conclusion that the loss of phenomenal awareness in blindsight may not be due to feedback activity in V1 being the hallmark awareness. On the basis of existing literature, an alternative explanation of blindsight is proposed. In this view, visual awareness is a “global” cognitive function as its hallmark is the availability of information to a large number of perceptual and cognitive systems; this requires inter-areal long-range synchronous oscillatory activity. For these oscillations to arise, a specific temporal profile of neuronal activity is required, which is established through recurrent feedback activity involving V1 and the extrastriate cortex. When V1 is lesioned, the loss of recurrent activity prevents inter-areal networks on the basis of oscillatory activity. However, as limited amount of input can reach extrastriate cortex and some extrastriate neuronal selectivity is preserved, computations involving comparison of neural firing rates within a cortical area remain possible. This enables “local” read-out from specific brain regions, allowing for the detection and discrimination of basic visual attributes. Thus blindsight is blind due to lack of “global” long-range synchrony, and it functions via “local” neural readout from extrastriate areas.

Discipline-specific writing for business students: Research, practice and pedagogy

In the past few years strong arguments have been made for locating academic writing in higher education within the students’ disciplinary contexts in the belief that a full understanding of the role and dynamic of writing can only be achieved if it is examined as a social practice in its context of production. This chapter reports on a study that examined the conceptualisations of writing for business by a group of undergraduate and postgraduate lecturers and students at the business school of a British university. Based on a critical analysis of the literature reviewed for the study, and the data collected, the chapter contributes to existing writing pedagogy with a number of research-informed transformative pedagogical applications for teaching discipline-specific writing for business. Such applications which combine context-oriented practices (e.g. raising awareness of the role of disciplinary values in shaping writing) and text-oriented activities (e.g. discipline-specific referencing) aim at influencing the pedagogic agenda for teaching writing in higher education. The chapter concludes with questions for reflection and discussion that provide an opportunity for readers to reflect upon their own teaching environment.

On the 'inherent' character of the right of states to self-defence

While there is no lack of studies on the use of armed force by states in self-defence, its qualification as an ‘inherent right’ in article 51 of the Charter of the United Nations has received little scholarly attention and has been too quickly dismissed as having no significance. The present article fills this gap in the literature. Its purpose is not to discuss the limits to which article 51 or customary international law submit the exercise of the right of self-defence by states, but to examine what its 'inherent’ character means and what legal consequences it entails. The article advances two main arguments. The first is that self-defence is a corollary of statehood as presently understood because it is essential to preserving its constitutive elements. The second argument is that the exercise of the right of self-defence must be distinguished from the right itself: it is only the former that may be delegated to other states or submitted to limitations under customary international law and treaty law. The right of self-defence, however, cannot be alienated and it takes precedence over other international obligations, although not over those specifically intended to limit the conduct of states in armed conflict or over non-derogable human rights provisions.
