Every Viewer has a Price: On the Differentiation of TV Channels

The authors analyzed the implications of targeted advertising on the equilibrium level of channel profile differentiation (e.g., in terms of political positioning), in free-to-air broadcasting industries. When consumers have no preferences over program content (e.g., entertainment vs. news) standard Hotelling type results apply. Market forces minimize differentiation while the optimal degree is at an intermediate level. As preferences over program content get somewhat stronger, the difference between optimal and market outcomes is initially reduced. However, when preferences over program content get more pronounced, minimal differentiation suddenly becomes optimal while market forces lead to excessive differentiation. Hence, policies aimed at increasing diversity are beneficial only when viewers care little about differences in program content.     

Advertising and Media Market Concentration

In media markets, the value of advertisement exposure depends on circulation, and media consumers' valuation is affected by advertising. This article analyzes media market competition in a duopoly framework. There exist symmetric and asymmetric equilibria in terms of firm size, and sometimes a natural monopoly may emerge. There is less scope for asymmetry when products are more differentiated. Some media exhibit public good features. This increases the scope for asymmetry when consumers value advertising positively. If their valuation is negative, only symmetric equilibria exist. Regulations limiting price competition increase the scope for natural monopoly.     

It is only an intervention,but it can sow very fertile seeds: graduate physical education teachers’ interpretations of critical pedagogy

The role that school health and physical education (HPE) plays in the making of physically active and healthy citizens continues to be rearticulated within the field of HPE practice. In Australasia, for example, this is evident in HPE curricula changes that now span almost two decades with ongoing advocacy for greater recognition of socially critical perspectives of physical activity and health. This paper reports on one part of a larger collaborative project that focused on how HPE teachers understand and enact socially critical perspectives in their practice. The paper draws on interview data obtained from 20 secondary school HPE teachers, all of whom graduated from the same physical education teacher education (PETE) programme in New Zealand, a programme that espouses a socially critical orientation. The teaching experience of the study participants ranged from 1 to 22 years of service. The preliminary analysis involved deduction of common themes in relation to the research questions and then, drawing on the theoretical framework of Bourdieu [1990. The logic of practice. Cambridge: Polity Press], these themes were analysed in more detail to gain insight into how and why the graduate teachers’ expressed their particular understanding of HPE and critical pedagogy. The findings suggested that this PETE programme did have some impact on the participant teachers’ perceptions of physical activity and health, and the role of socially critical thinking. However, there was also evidence to suggest that many of them did not have a clear understanding of the transformative agenda of critical pedagogy. We conclude by suggesting that although this PETE programme did plant ‘seeds’ that had an impact on the graduate teachers’ awareness and thinking about socially critical issues in relation to physical activity and health, it did not necessarily turn them into critical pedagogues.     

Older versions of the ROUGEeval summarization evaluation system were easier to fool

We show some limitations of the ROUGE evaluation method for automatic summarization. We present a method for automatic summarization based on a Markov model of the source text. By a simple greedy word selection strategy, summaries with high ROUGE-scores are generated. These summaries would however not be considered good by human readers. The method can be adapted to trick different settings of the ROUGEeval package.     

The UK National Student Survey: An amalgam of discipline and neo-liberal governmentality

The UK National Student Survey (NSS) has high status on the agenda of UK universities. Its rise in status is linked to its influence on national rankings and associated funding streams referenced to the Teaching Excellence Framework (TEF). Consequently, many universities have implemented further assessments of student satisfaction, thereby putting additional internal performative pressures on courses and individual lecturers. The research contribution of this article comprises an analysis of the NSS through Foucault's notion of ‘governmentality’, with a particular focus on his work on ‘discipline’ and ‘neo-liberal governmentality’. More specifically, by utilising qualitative data from interviews, research diaries and observations, it will be demonstrated how the NSS functions as a ‘disciplinary’ technology of government which subjects lecturers, departments and universities to intersecting panoptic gazes and perpetual ratings. In addition, the NSS can also be considered ‘neo-liberal’ in that it governs the academic population through narrow conceptions of ‘freedom’ and omnipresent competition. The article proposes that it is through the amalgamated forces of intersecting panoptic gazes, on the one hand, and neo-liberal free-market principles, on the other, that student feedback develops its power to govern.     

The walking rhythm of physical education teaching: an in-path analysis

Background: While studies of teaching frequently preserve an interest in teacher–pupil encounters that take place in certain spots, this article shows how teachers’ can be understood as in-path instructors, which is significant for student-based learning. This complements studies that have mainly focused on teachers instructional work taking place at certain spots.

Purpose: The purpose is to describe how a PE teacher’s rhythmic labouring of the diverse settings in the gym creates a learning environment. By examining emplacement (spatial) and empacement (temporal) as important aspects of how learning environments are constituted, this article contributes a framework for studying and analysing a teacher’s work from a moving vantage point.

Conclusions: Based on a video ethnographic approach and using a wearable camera attached to the teacher’s chest, the analysis of a station-wise lesson show how the teacher frequently covers a large part of the room and creates a web of educational challenges and possibilities. These brief encounters are identified as important tools that support each pupil’s rhythm and engagement in the learning activities and maintain the corporate rhythm of a class. Furthermore, by analysing the teacher’s temporal and spatial walking technique, which helps the pupils to transit between and accomplish practical exercises, the article highlights how the teacher’s ability to support pupils’ progression partly builds on a regional knowledge that is cultivated by the array of encounters.     

Videos Bridging Asia and Africa: Overcoming Cultural and Institutional Barriers in Technology-Mediated Rural Learning

Abstract

Will African farmers watch and learn from videos featuring farmers in Bangladesh? Learning videos on rice seed management were made with rural women in Bangladesh. By using a new approach, called zooming-in, zooming-out, the videos were of regional relevance and locally appropriate. When the Africa Rice Center (AfricaRice) introduced them to Africa in 2005, many scientists and civil servants thought that the videos would be culturally inappropriate and hence irrelevant to African smallholder farmers. However, African farmers who watched the videos did not experience cultural barriers. In fact, they enjoyed seeing another part of the world where farmers faced similar problems as theirs, and were able to solve these problems by themselves. To promote wider uptake of the videos a key challenge was to overcome the institutional barriers. Public sector agencies especially had to be convinced that African smallholders appreciated Asian videos. By watching the videos with farmers and listening to their feedback, the skeptical scientists and service providers changed their minds. By 2009, the Bangladeshi rice seed videos had been translated into 20 African languages and so became national products. Videos made according to the zooming-in zooming-out approach can bring farmer-to-farmer extension to a higher level of social aggregation.
