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

The Predictors of Graduation: Social Skills, Mental Health, Academic Characteristics

Abstract: Not completing the undergraduate course in the time expected in the curricula can put the universities and students at a disadvantage, with a delay to enter the labor market. The aim was to identify predictors of graduation, considering social skills, mental health, initial academic performance and socio-demographic and academic characteristics. In total, 287 students participated, of both genders and fromthe humanities, exact and biological areas, who answered the instruments: Social Skills, Behaviors and Context Assessment Questionnaire for University Students, Short version of the Social Phobia Inventory, Beck Depression Inventory, and Structured Clinical Interview for DSM-IV. Predictors were: female, humanities area and average or above-average initial academic performance. The social skills and mental health differentiated the groups in the univariate analyses. This data suggests a need for attention to academic performance in the initial stages of the course, and preventive measures for male students of the exact and biological areas

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

Siguiendo trayectorias, dibujando trayectos. Construcción de diagramas desde la experiencia de los habitantes

La práctica de dibujar se ha constituido desde el comienzo como una práctica anterior a lo verbal. Así, los dibujos rescatan y revelan una forma de escritura diferente, que permite comunicar, mediante la representación en una superficie, distintos procesos, sensaciones e ideas. El presente artículo explica el proceso de dibujo de diagramas que representan el trayecto de una mujer por Santiago de Chile. A partir de él, se levanta la noción de experiencia espacial dentro del espacio de la movilidad, mediante la cual es posible desarrollar un método de dibujo que evoluciona con el registro y la representación de ella. Para lo anterior, se discutirá la idea de espacialidad, conceptualizada desde la idea de Massey. Desde allí se desarrolla la idea de trayecto, como la forma en la cual las trayectorias de movilidad se vinculan con la espacialidad y el cuerpo de los habitantes de la ciudad. Como caso de estudio, se utiliza el sombreo realizado a un individuo y a partir de eso, se discute la forma en la que la representación de estas trayectorias se vuelve una parte central del proceso de investigación.Proyecto Fondecyt N° 1090198 “Movilidad Cotidiana Urbana y Exclusión Social Urbana en Santiago de Chile
