Dialectical Spaces in the Global Public Sphere: Media Memories across Generations
A decade ago, CNN and MTV emerged as new types of 'global' players, initiating and supporting a new global transnational community of 'news junkies' and music cultures from New York, to Tokyo, to Buenos Aires and Los Angeles. Today, access to international news is not only available in many countries around the world, but international channels have multiplied and created 'imagined communities' (Anderson, 1983), affecting new political alliances, conventional journalism and - increasingly - national public spheres. The following research report will discuss new issues of globalization and focus on the impact of media-related globalization processes on 'life-worlds' in various countries
Imagining biosocial communities: HIV, risk and gay and bisexual men in the North East of England
Many critics have charted an increasing biomedical and individualised approach to HIV prevention among gay and bisexual men, citing a significant shift in HIV policy and practice away from the community-based approaches to HIV prevention which characterised early responses. However, this dichotomous approach to âthe biomedical or the socialâ fails to capture the complex ways in which community-based approaches and sexual practice are already inextricably linked with the biomedical. This article explores how biomedical constructions of risk are embedded in the community-based bodily management and sexual practice of gay and bisexual men in the North East of England. Drawing on Paul Rabinowâs concept of âbiosocialityâ, the article proposes the notion of an imagined biosocial community: a community of gay and bisexual men who are affected by and at risk of HIV. Through this lens, the article explores how biomedical and sexual negotiations are situated in a broader history of illness, sexual politics and community. The article considers the importance of the biomedical in managing the body and the on-going significance of memory, community formation and identity in relation to âAIDSâ. It then explores how the interplay of these elements is deployed or threatened within these imagined community norms of sexual practice, where responsibility to others is critical. In paying attention to an imagined biosocial community, this article demonstrates how perceptions of and adherence to imagined community sexual practice remain critical in addressing risk of HIV in an increasingly biomedicalised context
Culturally responsive teacher actions to support PÄsifika students in mathematical discourse : a thesis presented in partial fulfilment of the requirements for the degree of Master of Education at Massey University, Palmerston North, New Zealand
This study examines culturally responsive teaching to support a group of PÄsifika students aged 11-13 years old in mathematical discourse. It builds on previous work which has advocated culturally responsive practices where students learn mathematics through collaborative interaction that fosters greater student participation, engagement, and potentially better achievement in mathematics. In this study, the teacherâs actions drew on PÄsifika cultural practices and the value of the family, respect, and collectivism. This was significant in the establishment of social and mathematical behaviours which were important in supporting the development of productive mathematical discourse. In addition, the communicative and participation structures within the classroom that lead to mathematics learning are also considered.
This study was situated in an inquiry classroom. A socio-cultural perspective provided the framework for analysing the classroom context. A case study approach drawing on a qualitative design was implemented. Data was collected through teacher and student interviews, classroom audio and video-recorded observations, and studentsâ written work. Detailed retrospective analysis of the data was undertaken to develop the findings of this classroom case study.
Significant changes were revealed in the shifts of student discourse from long silences and hesitation to asking valid questions and developing mathematical justification with appropriate language and specific terms. The explicit instructional practices developed and implemented by the teacher fostered greater collaborative communication and interaction between group members and this was important in how they made mathematical meaning. The findings provide insights into the multi-dimensional ways that teachers can draw on studentsâ cultural strengths, values, and practices as invaluable resources which potentially will make a difference in studentsâ mathematical learning
Bacteriological and epidemiological studies of campylobacter spp. in Swedish broilers
Campylobacter jejuni is the most frequently reported cause of bacterial gastrointestinal illness in humans in Sweden. Chicken products are considered an important risk factor for human infection. This thesis analyses and identifies sources and risk factors for colonisation of Campylobacter spp. in broilers at both farm level and slaughter. Slaughter groups with a low within-group prevalence were identified, split slaughter was confirmed as a risk factor and contamination of carcasses was shown to occur both during transport and during the slaughter process. Environmental campylobacter load was comparable on high and low incidence farms, indicating that hygiene regime is of greater importance than environmental load. Slaughter groups with a high within-flock prevalence had significantly higher campylobacter load in carcasses at slaughter than slaughter groups with a low degree of colonisation Campylobacter jejuni is the Campylobacter sp. predominantly found in broilers. Strain characterisation below species level, so-called subtyping, is a helpful tool in epidemiological studies, e.g. in determination of transmission routes. Certain subtypes were shown to be common in Sweden and may have a higher ability to survive in the environment around broiler houses. The results from phylogenetic analysis indicated that typing based on 16S rRNA sequencing is not always sufficient for differentiating between C. jejuni and C. coli. However, nine different 16S rRNA types were identified among 47 Swedish campylobacter isolates from broilers. About one-third of Swedish broiler producers seldom deliver any campylobacter-positive broilers to slaughter, demonstrating that it is possible to produce campylobacter-free chickens in Sweden. The factors identified as carrying the highest risk of producing campylobacter-positive broilers in Sweden were (i) insufficient general tidiness on the farm, (ii) split slaughter, (iii) an in-line position of the doors between the outside and access into broiler houses instead of an angled position. Furthermore, (iv) high risk farms often had other livestock such as cattle and pigs, and (v) high risk farms were more frequently situated in groves than in forest. Reducing the proportion of campylobacter-infected broiler flocks and the numbers of campylobacter on broiler carcasses would considerably lower the risk for consumers
The Future of Generic Biologics: Should the United States âFollow-Onâ the European Pathway?
The United States is embarking on a biotechnology drug revolution. In the last few decades, biotech drugs have saved millions of lives, and the market for these miracle cures continues to grow at an astronomical rate. Unfortunately, as the market for biotech drugs is skyrocketing, drug prices are following suit. As Congress strives to make these new drugs more affordable, it must not ignore significant safety concerns unique to these revolutionary therapies. Congress should follow the lead of the European Union to create an accessible pathway for generic forms of biotech drugs that includes strict regulatory measures to ensure drug safety and efficacy
