Tritrichomonas foetus: Prevalence study in naturally mating bulls in Switzerland

Switzerland is officially free from bovine Tritrichomonas foetus. While bulls used for artificial insemination (AI) are routinely examined for this pathogen, bulls engaged in natural mating, as well as aborted fetuses, are only very sporadically investigated, indicating that the disease awareness for bovine tritrichomoniasis is low. Natural mating in cattle is becoming increasingly popular in Switzerland. Accordingly, a re-introduction/re-occurrence of T. foetus in cattle seems possible either via resurgence from a yet unknown bovine reservoir, or via importation of infected cattle. The low disease awareness for bovine tritrichomoniasis might favor an unnoticed re-establishment of T. foetus in the Swiss cattle population. The aim of our study was thus to search for the parasite, and if found, to assess the prevalence of bovine T. foetus in Switzerland. We included (1) bulls over two years of age used in natural mating and sent to slaughter, (2) bulls used for natural service in herds with or without fertility problems and (3) aborted fetuses. Furthermore, the routinely examined bulls used for AI (4) were included in this study. In total, 1362 preputial samples from bulls and 60 abomasal fluid samples of aborted fetuses were analyzed for the presence of T. foetus by both in vitro cultivation and molecular analyses. The parasite could not be detected in any of the samples, indicating that the maximal prevalence possibly missed was about 0.3% (95% confidence). Interestingly, in preputial samples of three bulls of category 1, apathogenic Tetratrichomonas sp. was identified, documenting a proof-of-principle for the methodology used in this study.

Introduction XXIX European Seminar in Ethnomusicology: Cultural Mapping and Musical Diversity

«Cultural mapping» has become a central keyword in the UNESCO strategy to protect world cultural and natural heritage. It can be described as a tool to increase the awareness of cultural diversity. As Crawhall (2009) pointed out, cultural mapping was initially considered to represent the «landscapes in two or three dimensions from the perspectives of indigenous and local peoples». It thus transforms the intangible cultural heritage to visible items by establishing profiles of cultures and communities, including music traditions. Cultural mapping is used as a resource for a variety of purposes as broad as peace building, adaptation to climate change, sustainability management, heritage debate and management, but can also become highly useful in the analysis of conflict points. Music plays a significant role in each of these aspects. This year’s symposium invites to highlight, yet also to critically reassess this topic from the following ethnomusicological perspectives: - The method of cultural mapping in ethnomusicology What approaches and research techniques have been used so far to establish musical maps in this context? What kinds of maps have been developed (and, for example, how far do these relate to indigenous mental maps that have only been transmitted orally)? How far do these modern approaches deviate from the earlier cultural mapping approaches of the cultural area approaches that were still evident with Alan P. Merriam and in Alan Lomax` Cantometrics? In how far are the methods of cultural mapping and of ethnomusicological fieldwork different and how can they benefit from each other? - Intangible cultural heritage and musical diversity As the 2003 UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage pointed out in Article 12, each state signing the declaration «shall draw up, in a manner geared to its own situation, one or more inventories of the intangible cultural heritage, present in its territory and monitor these.» This symposium calls for a critical re-assessment of the hitherto established UNESCO intangible cultural heritage lists. The idea is to highlight the sensitive nature and the effects of the various heritage representations. «Heritage» is understood here as a selection from a selection – a small subset of history that relates to a given group of people in a particular place, at a specific time (Dann and Seaton 2001:26). This can include presentations of case studies, yet also a critical re-analysis of the selection process, e.g. who was included – or even excluded (and why)? Who were the decision makers? How can the role of ethnomusicology be described here? Where are the (existent and possible) conflict points (politically, socially, legally, etc.)? What kinds of solution strategies are available to us? How is the issue of diversity – that has been so strongly emphasized in the UNESCO declarations – reflected in the approaches? How might diversity be represented in future approaches? How does the selection process affect musical canonization (and exclusion)? What is the role of archives in this process? - Cultural landscape and music As defined by the World Heritage Committee, cultural landscapes can be understood as a distinct geographical area representing the «combined work of nature and man» (http://whc.unesco.org/en/culturallandscape/). This sub-topic calls for a more detailed – and general – exploration of the exact relation between nature/landscape (and definition of such) and music/sound. How exactly is landscape interrelated with music – and identified (and vice versa)? How is this interrelation being applied and exploited in a (inter-)national context?

Introduction: Sociolinguistics and tourism - mobilities, markets, multilingualism

In the introduction to this special issue on Sociolinguistics and Tourism, we focus on language in tourism as an important window into contemporary forms of economic, political, and social change. Our aim is twofold: (1) to establish and extend ‘sociolinguistics and tourism’ as another social and applied domain of sociolinguistic research; and (2) to use tourism as a lens for a broader discussion of the sociolinguistics of late modernity. To this end, we outline the contours of language and tourism research to date; we consider the (re)conceptualization of key thematics or notions in sociolinguistic research – such as ‘community’, ‘identity’, and ‘language’ itself – as particularly germane to the study of tourism's fleeting encounters; we examine the inevitable tensions between commodification and authenticity; and we explore the links between performances of ‘self’ and ‘other’, and the contestation of different identity positions with regard to social actors’ multilingual repertoires. We illustrate these issues with data examples from several tourist sites, where multilingual resources are deployed for identification, authentication and commodification. Finally, we briefly introduce the papers in this special issue and conclude by commenting on some sociolinguistic consequences of the study of language/s in tourism.
