Social stratigraphy in Late Iron Age Switzerland: Stable carbon, nitrogen and sulphur isotope analysis of human remains from Münsingen

The Iron Age cemetery of Münsingen in Switzerland with 220 abundantly equipped burials marked a milestone for Iron Age research. The horizontal spread throughout the time of its occupancy laid the foundation for the chronology system of the Late Iron Age. Today, skulls of 77 individuals and some postcranial bones are still preserved. The aim of the study was to obtain information about diet, mobility and social stratification of the individuals. Stable isotope ratios of carbon, nitrogen and sulphur were analysed for 63 individuals. For all of them C3 plants were found to be the staple food. There are significant differences between males and females in δ13C and δ15N values. This points to a gender restriction in the access to animal protein with males probably having more access to meat and dairy products. Differences in δ15N values were also observed for different age classes. δ34S values indicate a terrestrial-based diet with no significant intake of marine or freshwater fish. Seven adults with enriched δ34S values might have immigrated to Münsingen, four of which were found in the oldest part of the cemetery. Furthermore, possible changes of the vegetation are indicated by the more positive stable carbon ratios in the later phases. The results lead to the suggestion that especially males buried with weapons might have played a special role in the Iron Age society.

Sport as a means of immigrant youth integration: An empirical study of sports, intercultural relations, and immigrant youth integration in Switzerland

Der Beitrag geht der Bedeutung des Sports für die Integration von jugendlichen Einwanderern in die Aufnahmegesellschaft nach. Aufgrund von Daten einer Querschnittstudie bei 454 Jugendlichen der ersten Einwanderergeneration aus Gymnasien, Berufsschulen und Vorlehreeinrichtungen der deutschen Schweiz zeigen unsere Ergebnisse, dass der Sport für die meisten Jugendlichen mit Migrationshintergrund ein wichtiger Teil ihrer Freizeit darstellt, auch wenn der Anteil von Migrantinnen, die Mitglied eines Sportvereins sind, im Vergleich zu Migranten zweimal niedriger ausfällt. Zudem haben sowohl männliche wie weibliche Jugendliche mit Migrationshintergrund, die Sport in einem Sportverein ausüben, deutlich mehr persönliche Kontakte mit Schweizer Peers während ihrer sportlichen Aktivitäten. Jugendliche, die von häufigen persönlichen Kontakt mit Schweizer Peers im Sport berichten, haben auch deutlich mehr interkulturelle Kontakte in ihrer Freizeit generell und innerhalb des Kreises ihren engsten Freunde. Schließlich vermögen häufige Kontakte mit Schweizer Peers im Sport das Gefühl der jugendlichen Einwanderer, in der Schweiz integriert zu sein, zu erhöhen.

Courses in the language and culture of origin and their impact on youth development in cultural transition: A study among immigrant and dual heritage youth in Switzerland

Elena Makarova traces how the concept of intercultural education in German-speaking European countries promotes the inclusion of courses in the Language and Culture of Origin (LCO) for immigrant youth in the school curriculum of host countries. Such courses are assumed to have positive effects on the development of immigrant youth in the host country. Particularly, it has been suggested that participation in LCO courses increases the self-esteem of immigrant youth, facilitates the development of their bicultural identity and improves their integration in the host society. However, there is a lack of empirical evidence on the nature of the effects of LCO course attendance on the acculturation of immigrant youth and their cultural identity. Accordingly, the aim of the study detailed in the chapter is to examine the impact of immigrant youth’s attitudes towards LCO courses and of their attendance of such courses on their acculturation and cultural identity.

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.

The use of homeopathy in obstetrics in Switzerland

Objective In 1999, a first study conducted in the German speaking part of Switzerland revealed that homeopathy was used in 73% of the obstetrics. The aim of this follow-up study was to detect possible changes in the use of homeopathy since the first investigation, as well as to expand the survey to all regions of Switzerland in order to explore possible regional differences. Furthermore, the perceived positive and negative effects of homeopathy were of interest. Methods All maternity clinics (n = 119) and birthing centers (n = 25) in Switzerland were invited to participate in this online-survey (total N = 144). Results The data collection is still ongoing. Preliminary analyses show that of the 144 obstetrics contacted, 16 had shut down. 106 (82%) had returned the complete or partial questionnaire, whereof 86 (81%) were completed by maternity clinics and 20 (19%) by birthing centers. 70 (66%) questionnaires were returned from the German, 31 (29%) from the French and 5 (5%) from the Italian part of Switzerland. A total of 77 (73%) obstetrics indicated to apply homeopathy: 61 maternity clinics (71% of the responding ones) and 16 birth centers (80% of the responding ones). Clear regional differences in the use of homeopathy emerged: While 65 of the homeopathy-applying obstetrics were located in the German part of Switzerland (84% of the responding ones), only 11 (35% of the responding ones) and 1 (20% of the responding ones) were situated in the French and Italian regions respectively. More detailed results will be presented at the conference. Conclusion Preliminary results show that homeopathy is widely used in the obstetrics of Switzerland. Cultural differences appeared: Homeopathy is widely used in the German speaking part of Switzerland, while it is modestly employed in the French and Italian regions.

Dental fear and satisfaction with dental services in Switzerland.

OBJECTIVES Dental satisfaction is associated with continuity of dental care, compliance with dentist advice, and positive health outcomes. It is expected that people with higher dental fear might have less dental satisfaction because of more negative dental experiences. The objective of this study was to examine satisfaction and reasons for satisfaction with dental practitioners in Switzerland and variations by dental fear. METHODS A national sample of 1,129 Swiss residents aged 15-74 (mean = 43.2 years) completed a personal interview at their home with questions assessing dental fear, dental service use, general satisfaction with their dentist, and reasons for satisfaction or dissatisfaction. RESULTS Overall, 47.9 percent of participants responded that they were satisfied with their dentist and 47.6 percent that they were very satisfied. Satisfaction differed significantly by gender, language spoken, region of residence, and educational attainment. Greater dental fear was significantly associated with greater dissatisfaction with the dentist. The percentage of people who were very satisfied with the dentist ranged from 56.0 percent among people with no fear to 30.5 percent for participants with "quite a lot" of fear but was higher (44.4 percent) for people who stated that they were "very much" afraid of the dentist. The most common reasons attributed for satisfaction with dentists were interpersonal characteristics of the dentist and staff. People with "quite a lot" of fear were found to endorse these sentiments least. CONCLUSIONS Although higher dental fear was associated with more dissatisfaction with the dentist, the level of satisfaction among fearful individuals in Switzerland is still high.

Education for specialization in prosthodontics in Switzerland and the role of EPA.

Advertisement for any dental treatment was rare in Switzerland. Then the use of digital media became popular, particularly in the field of implant- and esthetic-dentistry. In parallel to the dental schools of public universities, private universities and companies built up centers for continuing education that issue specialists diplomas and M.Sc. degrees. Prosthodontics itself is characterized by many sub-disciplines that incorporated their own associations. These also offer graduate training curricula which diminish the significance of specialization in prosthodontics. Specialized prosthodontists do not have a financial benefit in Switzerland where dentistry is not supported by any insurance. In other European countries funding of prosthodontic treatment depends on their healthcare systems. There are four specialties in Dentistry recognized by the European Union (EU). Specialization in prosthodontics was introduced in Sweden already in 1982 and today it is declared in about 20 European countries, while for others no recognized program exists. Thus there are great variations with more recognized specialists in former east European countries. In Switzerland the prosthodontic specialization curriculum was developed and guided by the Swiss Society for Reconstructive Dentistry, and only in 2001 it became fully acknowledged by the Federal Department of Health. The four Swiss Universities offer the 3-year program under the supervision of the society, while the government remains the executive body. In 2003 EPA tried to set up guidelines and quality standards for an EPA recognized specialization. In spite of these attempts and the Bologna Reform in Europe, it appears that the quality standards and the level of education still may differ significantly among European countries.

Highlights in Analytical Chemistry in Switzerland: OMA & OPA - A Software Tool for Mass Spectrometric Sequencing of Nucleic Acids

Oligonucleotides comprising unnatural building blocks, which interfere with the translation machinery, have gained increased attention for the treatment of gene-related diseases (e.g. antisense, RNAi). Due to structural modifications, synthetic oligonucleotides exhibit increased biostability and bioavailability upon administration. Consequently, classical enzyme-based sequencing methods are not applicable to their sequence elucidation and verification. Tandem mass spectrometry is the method of choice for performing such tasks, since gas-phase dissociation is not restricted to natural nucleic acids. However, tandem mass spectrometric analysis can generate product ion spectra of tremendous complexity, as the number of possible fragments grows rapidly with increasing sequence length. The fact that structural modifications affect the dissociation pathways greatly increases the variety of analytically valuable fragment ions. The gas-phase dissociation of oligonucleotides is characterized by the cleavage of one of the four bonds along the phosphodiester chain, by the accompanying loss of nucleases, and by the generation of internal fragments due to secondary backbone cleavage. For example, an 18-mer oligonucleotide yields a total number of 272’920 theoretical fragment ions. In contrast to the processing of peptide product ion spectra, which nowadays is highly automated, there is a lack of tools assisting the interpretation of oligonucleotide data. The existing web-based and stand-alone software applications are primarily designed for the sequence analysis of natural nucleic acids, but do not account for chemical modifications and adducts. Consequently, we developed a software to support the interpretation of mass spectrometric data of natural and modified nucleic acids and their adducts with chemotherapeutic agents.

Opioid maintenance therapy in Switzerland: an overview of the Swiss IMPROVE study

BACKGROUND/AIMS: Switzerland’s drug policy model has always been unique and progressive, but there is a Need to reassess this system in a rapidly changing world. The IMPROVE study was conducted to gain understanding of the attitudes and beliefs towards opioid maintenance therapy (OMT) in Switzerland with regards to quality and Access to treatment. To obtain a “real-world” view on OMT, the study approached its goals from two different angles: from the perspectives of the OMT patients and of the physicians who treat patients with maintenance therapy. The IMPROVE study collected a large body of data on OMT in Switzerland. This paper presents a small subset of the dataset, focusing on the research design and methodology, the profile of the participants and the responses to several key questions addressed by the questionnaires. METHODS: IMPROVE was an observational, questionnaire-based cross-sectional study on OMT conducted in Switzerland. Respondents consisted of OMT patients and treating physicians from various regions of the country. Data were collected using questionnaires in German and French. Physicians were interviewed by phone with a computer-based questionnaire. Patients self-completed a paper-based questionnaire at the physicians’ Offices or OMT treatment centres. RESULTS: A total of 200 physicians and 207 patients participated in the study. Liquid methadone and methadone tablets or capsules were the medications most commonly prescribed by physicians (60% and 20% of patient load, respectively) whereas buprenorphine use was less frequent. Patients (88%) and physicians (83%) were generally satisfied with the OMT currently offered. The current political framework and lack of training or information were cited as determining factors that deter physicians from engaging in OMT. About 31% of OMT physicians interviewed were ≥60 years old, indicating an ageing population. Diversion and misuse were considered a significant problem in Switzerland by 45% of the physicians. CONCLUSION: The subset of IMPROVE data presented gives a present-day, real-life overview of the OMT landscape in Switzerland. It represents a valuable resource for policy makers, key opinion leaders and drug addiction researchers and will be a useful basis for improving the current Swiss OMT model.

Patterns of Religious Education Policy in Switzerland. The Long Arm of Distanced Christians?

In spite of its different cantonal jurisdictions and traditions, the development of religious education in Switzerland over the past decade has taken a common direction: the state has assumed a more active role in the field of religious education in public (state-run) schools. In this article, we ask the question: How do key social actors interpret these reforms and how do these interpretations relate to the social structure of religion in Switzerland, in particular with respect to the majority category of the so-called distanced Christians? Drawing on qualitative interviews with members of the schools’ teaching staff, school administrators, and church representatives, the article highlights a dominant interpretative pattern that frames the socially accepted representation of religion in public schools. Thus, rather than addressing the pedagogical dimension of religious education, we discuss the significance of this pattern for the debate on the public presence of religion in Switzerland and Europe.
