The CHilean Automatic Supernova sEarch (CHASE)
The CHASE project started in 2007 with the aim of providing young southern
supernovae (SNe) to the Carnegie Supernova Project (CSP) and Millennium Center
for Supernova Studies (MCSS) follow-up programs. So far CHASE has discovered 33
SNe with an average of more than 2.5 SNe per month in 2008. In addition to the
search we are carrying out a follow-up program targeting bright SNe. Our fully
automated data reduction allows us to follow the evolution on the light curve
in real time, triggering further observations if something potentially
interesting is detectedComment: 4 pages, 2 figures, conference proceedin
Plantando, colhendo, vendendo, mas não comendo: práticas alimentares e de trabalho associadas à obesidade em agricultores familiares do Bonfim, Petrópolis, RJ.
Objetivo: verificar a prevalência de obesidade entre adultos das 86 famílias agricultoras de um bairro de Petrópolis, RJ, e analisar seus determinantes socioculturais. Métodos: estudo quantitativo e qualitativo sobre nutrição, práticas alimentares e de trabalho realizado em 2008. Dados antropométricos foram coletados por inquérito nutricional domiciliar e o material qualitativo por observação participante e entrevistas. Resultados: a prevalência de obesidade foi baixa (9,3%) entre os homens, mas bastante elevada entre as mulheres (29,9%). A prática agrícola local implica em atividade física leve para mulheres e intensa para homens. Essa diferença não é acompanhada na dieta, semelhante para homens e mulheres, com predomínio de alimentos de alto valor calórico. A produção familiar objetiva essencialmente a venda. A agricultura mercantil e a decorrente especialização dos cultivos favorecem comprar alimentos no mercado em vez de produzir para autoconsumo. Conclusão: os aspectos socioculturais e ocupacionais estudados podem ter contribuído para elevar a prevalência de obesidade nas mulheres e podem ser úteis no estudo de outros grupos com características semelhantes. Esta pesquisa ratifica a importância de estudar a obesidade em nível local, integrando abordagens quantitativas e qualitativas para identificar possíveis limitações e portas de entrada para ações de intervenção localmente relevantes
(I)Migrantes, diversidades e desigualdades no sistema educativo português : balanço e perspectivas
O objectivo do presente artigo consiste
em procurar transmitir um olhar sociologicamente informado no que concerne à situação portuguesa no domínio das políticas
educativas públicas e investigações produzidas relacionadas com o sistema educativo e a (i)migração, ou seja, com a tentativa de construção de uma educação
intercultural. Neste sentido, será realizada
uma análise descritiva e compreensivo-interpretativa da evolução desta
problemática em Portugal desde que a mesma se tornou objecto de reflexão por parte de investigadores/as e políticos nos finais da
década de oitenta, início da década de noventa do século XX. Nesta análise, será
dada ênfase às investigações e quadros teóricos produzidos e às medidas legislativas
e políticas educativas no domínio do tratamento da diferença cultural dentro do sistema educativo português.The aim of this article consists in attempting to
transmit a sociologically informed view in what the Portuguese situation in the field of public policies and research related to
the educational system and (im)migration are
concerned, that is, in attempting to construct an intercultural education. In this way, a descriptive and comprehensiveinterpretative
analysis of the evolution of this problem in Portugal will be realized, since the latter became an object of reflection on the part of researchers and politicians towards the end of the 80s, the beginning of the 90s of the XXth century. In this analysis, emphasis will be given on the research and theoretical frameworks produced and on the legislative measures and educational policies in the field of treating cultural difference in the
Portuguese educational system
Chromosome landmarks and autosome-sex chromosome translocations in Rumex hastatulus, a plant with XX/XY1Y2 sex chromosome system
Rumex hastatulus is the North American endemic dioecious plant with heteromorphic sex chromosomes. It is differentiated into two chromosomal races: Texas (T) race characterised by a simple XX/XY sex chromosome system and North Carolina (NC) race with a polymorphic XX/XY1Y2 sex chromosome system. The gross karyotype morphology in NC race resembles the derived type, but chromosomal changes that occurred during its evolution are poorly understood. Our C-banding/DAPI and fluorescence in situ hybridization (FISH) experiments demonstrated that Y chromosomes of both races are enriched in DAPI-positive sequences and that the emergence of polymorphic sex chromosome system was accompanied by the break of ancestral Y chromosome and switch in the localization of 5S rDNA, from autosomes to sex chromosomes (X and Y2). Two contrasting domains were detected within North Carolina Y chromosomes: the older, highly heterochromatinised, inherited from the original Y chromosome and the younger, euchromatic, representing translocated autosomal material. The flow-cytometric DNA estimation showed ∼3.5 % genome downsizing in the North Carolina race. Our results are in contradiction to earlier reports on the lack of heterochromatin within Y chromosomes of this species and enable unambiguous identification of autosomes involved in the autosome-heterosome translocation, providing useful chromosome landmarks for further studies on the karyotype and sex chromosome differentiation in this species
Functional Annotation of All Salmonid Genomes (FAASG): an international initiative supporting future salmonid research, conservation and aquaculture
We describe an emerging initiative - the 'Functional Annotation of All Salmonid Genomes' (FAASG), which will leverage the extensive trait diversity that has evolved since a whole genome duplication event in the salmonid ancestor, to develop an integrative understanding of the functional genomic basis of phenotypic variation. The outcomes of FAASG will have diverse applications, ranging from improved understanding of genome evolution, to improving the efficiency and sustainability of aquaculture production, supporting the future of fundamental and applied research in an iconic fish lineage of major societal importance

Multilocus DNA-fingerprinting using oligonucleotide probes (GATA)4 and (GGAT)4 in rainbow trout (Oncorhynchus mykiss)
Oligonucleotide probes (GATA)4 and (GGAT)4 for minisatellite loci produced DNA fingerprinting patterns which are unique in individual rainbow trout. These patterns can be used to monitor the efficiency of manipulation of production characters in gynogenetic individuals. The (GATA)4 probe produced highly individual patterns that differentiated individuals among gynogenetic offspring, and could be easily scored
Relearning to travel in Santiago: the importance of mobile place-making and travelling know-how
Cities today are experiencing constant, significant and abrupt infrastructural and spatial transformations. This is particularly evident in Metropolitan cities and more specifically, in cities in the Global South. Over the last decade, the implementation of Transantiago-a new public transport system-created greater awareness about the relevance of mobility practices in everyday life in the city. The intervention generated general unrest and particular daily challenges to Santiago’s residents requiring them to suddenly adapt, relearn and create ways of making sense of the complex situation that took place. It also generated major challenges for Transantiago implementers, who had to quickly react to the importance of everyday mobility experiences. Based on ethnographic research on mobility practices in Santiago de Chile prior and after Transantiago, this article presents the idea of mobile place-making as well as the various strategies urban travellers develop to adapt and create new ways of making sense of the city on a daily basis as it transforms. The results explore how travellers creatively find ways of learning or relearning to use new mobile spaces based on a travelling know-how which thickens the more mobility is practised, thus providing new possibilities within these places on the move
