Social integration of Ethiopian and Eritrean women in Switzerland through informal sport settings
2021
This study investigated the role of informal sport settings (i.e. self-organised and non-voluntary sports clubs) in the social integration of Ethiopian and Eritrean women into Swiss society. Social integration seen as a multidimensional, interdependent process between the interaction of social bond, bridge and links; and two-way interaction between the migrant and local community. Thematic analysis of semi-structured interviews and focus group discussions (n���=���12, 18���51���years old) was used to understand the interplay between social integration and participation in informal sport settings. The findings indicated that such settings have become a crucial sphere for establishing and reb…
What Are the Success Factors of Multilingual Families? Relationships Between Linguistic Attitudes and Community Dynamics
2021
The research focuses on the influence of emotional, cognitive, and social climate on the language choices of multilingual families, and the impact they can have on their general well-being, intergenerational relationships, and the community context. The methodological framework of reference is Grounded Theory. Collected data concern language practices, attitudes, emotions, and generational, trigenerational, and social interactive dynamics of multilingual families. The results include key insights into the variables underlying the linguistic attitudes of multicultural families. Two Network Views suggest that linguistic attitudes, such as the conscious management of specific and complex dynam…
International retirement migration revisited: From amenity seeking to precarity migration?
2018
International retirement migration has become a multifaceted field of research since the end of the twentieth century. The term refers to mobilities in old age to other countries, upon reaching ret...
“As Many as Possible for as Long as Possible”—A Case Study of a Soccer Team That Fosters Multiple Outcomes
2021
The personal assets framework suggests that dynamic elements of (a) personal engagement in activities, (b) quality social dynamics, and (c) appropriate settings will influence an athlete’s long-term outcomes of performance, personal development, and continued participation in sport. The aim of the present study was to conduct a case study of a Norwegian age-restricted team that was successful in promoting participation, performance, and positive development for individual participants and to investigate how the dynamic elements of activities, social dynamics, and settings have led to these long-term outcomes. The results indicated that the case is a best-practice example of successful attai…
Influence of Biologically Oriented Preparation Technique on Peri-Implant Tissues; Prospective Randomized Clinical Trial with Three-Year Follow-Up. Pa…
2019
Purpose: The objective of this prospective randomized clinical trial (RCT) was to analyze and compare the clinical behavior of three types of prosthesis supported by single implants in the posterior region after three years functional loading. Materials and Methods: Seventy-five implants were divided into three groups according to the type of prosthetic restoration: screw-retained crown (Group GS); cemented crown without finishing line (biologically oriented preparation technique) (Group GBOPT); and conventional cemented crown with finishing line (Group GCC). The clinical behavior of each restoration type was analyzed after 3 years functional loading by analyzing radiographic peri-implant b…

ABSTRACT The vertical structuring of methanotrophic communities and its genetic controllers remain understudied in the water columns of oxygen-stratified lakes. Therefore, we used 16S rRNA gene sequencing to study the vertical stratification patterns of methanotrophs in two boreal lakes, Lake Kuivajärvi and Lake Lovojärvi. Furthermore, metagenomic analyses were performed to assess the genomic characteristics of methanotrophs in Lovojärvi and the previously studied Lake Alinen Mustajärvi. The methanotroph communities were vertically structured along the oxygen gradient. Alphaproteobacterial methanotrophs preferred oxic water layers, while Methylococcales methanotrophs, consisting of putative…
'Palaeoshellomics' reveals the use of freshwater mother-of-pearl in prehistory
2019
The extensive use of mollusc shell as a versatile raw material is testament to its importance in prehistoric times. The consistent choice of certain species for different purposes, including the making of ornaments, is a direct representation of how humans viewed and exploited their environment. The necessary taxonomic information, however, is often impossible to obtain from objects that are small, heavily worked or degraded. Here we propose a novel biogeochemical approach to track the biological origin of prehistoric mollusc shell. We conducted an in-depth study of archaeological ornaments using microstructural, geochemical and biomolecular analyses, including ‘palaeoshellomics’, the first…
Ancient cattle genomics, origins, and rapid turnover in the Fertile Crescent
2019
Cattle were domesticated ∼10,000 years ago, but analysis of modern breeds has not elucidated their origins. Verdugo et al. performed genome-wide analysis of 67 ancient Near Eastern Bos taurus DNA samples. Several populations of ancient aurochs were progenitors of domestic cows. These genetic lineages mixed ∼4000 years ago in a region around the Indus Valley. Interestingly, mitochondrial analysis indicated that genetic material likely derived from arid-adapted Bos indicus (zebu) bulls was introduced by introgression.Science, this issue p. 173Genome-wide analysis of 67 ancient Near Eastern cattle, Bos taurus, remains reveals regional variation that has since been obscured by admixture in mode…
A population genomics analysis of the native Irish Galway sheep breed.
2019
SUMMARYThe Galway sheep population is the only native Irish sheep breed and represents an important livestock genetic resource, which is currently categorised as “at-risk”. In the present study, comparative population genomics analyses of Galway sheep and other sheep populations of European origin were used to investigate the microevolution and recent genetic history of the breed. These analyses support the hypothesis that British Leicester sheep were used in the formation of the Galway breed and suggest more recent gene flow from the Suffolk sheep breed. When compared to conventional and endangered breeds, the Galway breed was intermediate in effective population size, genomic inbreeding a…
Cold adaptation drives population genomic divergence in the ecological specialist, Drosophila montana
2020
Funding: UK Natural Environment Research Council (Grant Number(s): NE/L501852/1, NE/P000592/1); Academy of Finland (GrantNumber(s): 267244, 268214, 322980), Ella ja Georg Ehrnroothin Säätiö. Detecting signatures of ecological adaptation in comparative genomics is challenging, but analysing population samples with characterised geographic distributions, such as clinal variation, can help identify genes showing covariation with important ecological variation. Here, we analysed patterns of geographic variation in the cold-adapted species Drosophila montana across phenotypes, genotypes and environmental conditions and tested for signatures of cold adaptation in population genomic divergence. We…
