This study evaluated the changes of cows’ milk fat fatty acids (FA) after transition from pasture to a total mixed ration (TMR) diet and back to pasture. Eight Holstein cows were used in a 52-d experiment divided into three periods. In period I (PI), cows grazed for 10 d and were supplemented with 5 kg head−1 day−1 of concentrate. On the 11th day, cows were moved to a barn and fed a TMR diet for the next 21 d (PII). On the 32nd day, cows were sent back to pasture for another 21 d (PIII) and received the same supplement of PI. Milk samples were taken on days 10 of PI and 2, 4, 7, 14 and 21 of PII and PIII. Total mixed ratio significantly increased dry matter intake and milk production and decreased milk fat content. Diet significantly affected the concentration of most FA in milk fat. Grazing pasture significantly increased the concentrations of 18:0, 18:1 c9, 18:1 t11, 18:2 c9,t11, 18:2 t11,c15, 18:3 c9,c12,c15, iso and anteiso branched-chain FA and sums of monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA). Concentrations of 12:0, 14:0, 16:0, 15:0, 17:0, 18:2 c9,c12 and the sum of saturated fatty acids (SFA) significantly increased with PII diet. Most FA and FA sums took 14–21 d to stabilise in PII and only 4–7 d after transition for pasture. This evolution pattern of milk fat FA suggests that the long historical feeding regimen is a factor that impacts on the time cows take to respond to different diets by changing FA composition, probably as a result of the adaptation time of rumen microbes.

ResumoA Escala de Condutas Antissociais e Delitivas tem vindo a ser usada em vários países como uma medida comportamental do desvio juvenil, evidenciando resultados muito consistentes. Este artigo apresenta e discute a análise da validade empírica da estrutura fatorial da sua versão Portuguesa. A amostra foi constituída por 443 estudantes, 305 do sexo feminino e 138 do sexo masculino, com idades compreendidas entre os 15 e os 23 anos de idade (M = 14,8; DP = 1,90; Mo = 20), maioritariamente de nacionalidade portuguesa (92,1%). Em 60,6% dos casos os/as estudantes frequentavam a universidade. Os resultados sugerem a adequação psicométrica do instrumento, corroborando a estrutura bifatorial proposta em estudos prévios. São discutidas as potencialidades da utilização do instrumento em Portugal. AbstractThe Scale of Antisocial and Criminal Conducts has been used in several countries as a behavioral measure, showing very consistent results. This paper presents and discusses the analysis of the empirical validity of the factorial structure of its Portuguese version. The sample was comprised of 443 students, 305 female and 138 male, aged between 15 and 23 years (M = 14.8; SD = 1.90; Mo = 20), mostly Portuguese (92%), and 60.6% were college students. Results suggest the psychometric adequacy of instrument, confirming the bi-factorial structure proposed in previous studies. Advantages of its use with the Portuguese population are discussed.

Summary The diet, feeding success (prey number and total volume per gut, and maximum prey width) and trophic niche width of the labrisomid blenny Auchenionchus variolosus (Valenciennes, 1836) was studied during its larval development (3.93–17.26 mm standard length). Individuals were collected in October 2012 and October 2013 in nearshore waters (

Resenha sobre o livro MULHERES E CRIME: PERSPETIVAS SOBRE INTERVENÇÃO, VIOLÊNCIA E RECLUSÃO organizado pelas professoras Sílvia Gomes e Rafaela Granja

Multidisciplinary research in the area of female crime and delinquency has increasingly focused on transgressive girls and women. Despite this, discussions on the link between gender and crime or delinquency still have a long way to go. In order to explore critically and reflectively the interdisciplinary views on this link, favouring a gender-sensitive reading, we proposed this book. Through the exploration of girls’ and women’s relationships with delinquency and crime, as well as with the justice system, our goal is to highlight the heterogeneity of girls’ and women’s experiences, while debating convergences and divergences between them. While obviously not ignoring international studies on the phenomena, the discussion produced here is focused on the Portuguese context, giving visibility to other geographies in scientific investigation.

This chapter is the result of a qualitative investigation in which the main goal was to understand the problem of feminine juvenile delinquency, by studying the experiences and the meanings of the transgressions in the life paths of girls under educational court orders (executed in a juvenile detention center or within the community) in Portugal. Through the voices of the girls it was possible to create profiles of the transgressive paths that show the heterogeneity of the phenomenon of feminine juvenile delinquency and propose a way of overcoming the victimization-versus-agency dichotomy.

Tendo por pano de fundo as profundas mudancas demograficas, sociais e economicas registradas nos ultimos anos no tecido (sub)urbano em Portugal, neste artigo promove-se um dialogo dinâmico entre duas investigacoes qualitativas desenvolvidas pelas autoras com criancas e jovens envolvidos em violencia e delinquencia na sociedade portuguesa. No entrecruzamento entre os principais resultados de ambas, centra-se o olhar sobre como criancas e jovens representam a sua participacao em atos de violencia e delinquencia em contexto urbano e como sentem a exposicao a violencia urbana. Ter em consideracao o olhar das criancas e dos jovens sobre os problemas sociais que os afetam abre horizontes que remetem para a sua compreensao como atores sociais na construcao da realidade e da mudanca social nas mais variadas dimensoes. Deste modo, as formas como percecionam, representam e se relacionam com desordens e violencia nos locais onde residem nao podem ser dissociadas dos processos de socializacao e modos de vida que ai desenvolvem e sobre os quais tambem intervem. Traz-se ainda para discussao a influencia da dimensao do genero nestas problematicas, salientando as diferentes expressoes que estes fenomenos assumem, bem como determinados contornos identificados no processo de aprendizagem social da delinquencia.

This study assesses seasonal variation in the morphology and diet of juveniles and adults of the Easter Island endemic goby Kelloggella disalvoi from intertidal pools during September-October 2015 (spring) and June-July 2016 (winter), utilizing geometric morphometric and gut-content analyses. A set of 16 landmarks was digitized in 128 individuals. Shape changes related to size changes (i.e. allometry) were low (18·6%) and were seasonally similar. Body shape changes were mainly dorsoventral (44·2% of variance) and comprised posteroventral displacement of the premaxilla and bending of the body. The latter included vertical displacement of the anterior portion of the first and second dorsal fins and the entire base of the caudal fin. Diets mainly comprised developmental stages of harpacticoid copepods (from eggs to adults), ostracods, isopods, gastropods and bivalves. Also, trophic niche breadth remained constant throughout development and did not vary between seasons. Nonetheless, significant dietary differences were detected in specimens collected during spring (main prey items: harpacticoid copepods and copepod eggs) and winter (harpacticoid copepods and copepod nauplii). Finally, there was weak but significant covariation between diet and morphology: molluscivores were characterized by having an inferior mouth gape, whereas planktivores had an anteriorly directed premaxilla.

Este artigo resulta da investigação que foi desenvolvida no âmbito da minha tese de doutoramento em Sociologia que procurou entender a problemática da delinquência juvenil feminina, especificamente as experiências e os significados da transgressão nos percursos de vida de raparigas. Assumindo como referente empírico as jovens em cumprimento de medidas tutelares educativas analisaram-se processos individuais e realizaram -se entrevistas, cujo cruzamento permitiu explorar os contextos e os discursos dominantes e traçar percursos transgressivos. This article results from a research that was developed as part of my doctoral thesis in sociology about the experiences and meaning of transgression in the life paths of girls. Assuming that the empirical referent of this study included girls in compliance with educational court orders, individual cases were analysed and interviews were carried out. Their intersection allowed for the exploration of contexts and dominant discourses, and of pathways of transgression. Cet article est le résultat de la recherche qui a été réalisé dans le cadre de ma thèse de doctorat en sociologie qui a eu pour but de comprendre le problème de la délinquance juvénile féminine, et en particulier les expériences et les significations de la transgression dans les trajets de la vie des jeunes filles. En ayant comme référence empirique des jeunes filles soumises à des mesures de tutelle éducative, nous avons analysé les dossiers individuels et réalisé des entretiens qui ont permis d’explorer les contextes et les discours dominants et de définir les parcours transgressifs.

Entre muitos desafios assumidos, com a independência do país em 1975, a Educação, enquanto aposta estratégica, constituiu-se na prioridade das prioridades face a uma população de 275.613, no ano de1979 ,em sua maioria analfabeta (63%). O Ensino B��sico elementar de quatro anos não acessível a todas as crianças, o ensino secundário circunscrito apenas a um número muito reduzido de alunos e um corpo docente para os dois níveis, na sua maioria sem formação adequada (apenas cerca de 19%, com formação considerada adequada).(Leia mais)

In this study, we compare Portuguese and Cape Verdean youths’ upholding of traditional beliefs about intimate partner violence (IPV) and the frequency of selfreported violent behavior in dating relationships. The sample (n =404) consisted of 183 Cape Verdean and 221 Portuguese secondary school students of both sexes (56 % female; mean age = 16). We used two questionnaires that had previously been validated in the Portuguese population. The results revealed that young Cape Verdean adolescents uphold stronger traditional beliefs than Portuguese adolescents do, but there were no differences in overall prevalence of abuse between the two samples. The relationship between traditional beliefs and self-reported violence was significant only in the Cape Verdean sample, suggesting that campaigns against IPV have not, so far, been as effective in Cape Verde as in Portugal. info:eu-repo/semantics/publishedVersion

Em resposta ao predomínio masculino nos estudos sobre delinquência juvenil, este artigo explora uma das suas faces invisíveis, aquela que é praticada por raparigas. Discutindo a “história única” que se tem construído sobre a delinquência juvenil feminina, apresentam-se resultados de uma pesquisa qualitativa, realizada no âmbito de uma tese de doutoramento, sobre experiências e significados da transgressão nos percursos de vida de raparigas em cumprimento de medidas tutelares educativas em Portugal. A elaboração de retratos sociológicos, a partir da análise dos processos individuais e das entrevistas realizadas, permitiu traçar perfis de percursos transgressivos que mostram a heterogeneidade da delinquência feminina e (re)colocam as jovens como sujeitos sociais. In response to the predominance of the male in studies on juvenile delinquency, this article explores one of the latter’s invisible faces — delinquency by girls. A discussion of the “single story” that has been constructed about female juvenile delinquency is accompanied by the presentation of results from qualitative research conducted as part of a doctoral thesis on experiences and meanings of transgression in the life paths of girls subject to youth custody, protection and re-education measures in Portugal. An analysis of individual processes and interviews allowed the author to draw up sociological portraits that in turn made it possible to outline transgressive paths which show the heterogeneity of female delinquency and (re)situate the young women as social subjects. En réponse à la prédominance masculine dans les études sur la délinquance juvénile, cet article aborde l’une de ses faces invisibles, celle qui est pratiquée par les filles. À contre-pied de “l’histoire unique ” construite autour de la délinquance juvénile féminine, cet article présente les résultats d’une recherche qualitative, menée dans le cadre d’une thèse de doctorat, sur les expériences et les significations de la transgression dans les parcours de vie de filles faisant l’objet de mesures éducatives au Portugal. L’élaboration de portraits sociologiques, à partir des dossiers individuels et des entretiens réalisés, a permis de tracer des profils de parcours transgressifs qui montrent l’hétérogénéité de la délinquance féminine et (re)situent ces jeunes filles en tant que sujets sociaux. En respuesta al predominio masculino en los estudios sobre la delincuencia juvenil, este artículo explora una de sus caras invisibles, aquella que es practicada por jovencitas. Discutiendo la “historia única” que se ha construido sobre la delincuencia juvenil femenina, se presentan resultados de una investigación cualitativa realizada en el ámbito de una tesis de doctorado sobre experiencias y significados de la transgresión en los trayectos de vida de jovencitas bajo contexto de medidas tutelares educativas en Portugal. La elaboración de retratos sociológicos a partir del análisis de los procesos individuales y de las entrevistas realizadas permitió trazar perfiles de trayectos transgresivos que muestran la heterogeneidad de la delincuencia femenina y (re)ubican a las jóvenes como sujetos sociales.

Com a devida vênia, por estar a meter a foice em seara alheia, pois souapenas uma diletante, quer da história, quer da literatura, defendo que existeuma relação intrínseca entre história e literatura, ou seja, ambas se subsidiam,sobretudo, se tivermos em atenção os países africanos, nos quais aindapersiste uma cultura de oralidade.

El calor de radiación depende de la emisividad del cuerpo y de la temperatura a la que éste se encuentra. En el caso de los productos que se generan por combustibles líquidos, se considera la emisividad luminosa, causada por la flama, y la emisividad no luminosa, producida por los gases. Se establece una comparación entre el cálculo de la emisividad no luminosa descrita por Michael Modest en su libro Radiative heat transfer y los cálculos propuestos por Prabir Basu, Cen Kefa y Louis Jestin, en su libro Boilers and burnes, design and theory. Además, se contrasta el total de la energía de radiación calculada por ambos métodos. The heat radiation emissivity is characterized by having the body and the temperature at which this is. In the case of products generated by liquid fuels should be considered luminous emissivity caused by the flame, and no light emissivity by gases. A comparison between the calculation of the non-luminous emissivity described by Michael Modest in his book Radiative heat transfer and the calculations proposed by Prabir Basu, Cen Kefa y Louis Jestin in their book Boilers and burnes, design and theory, is established. Furthermore, the total radiation energy calculated by both methods contrasts.

Introduction: the first birth is an event in the life of people and therefore in their development process. The implications that stem from changes arising on many different levels require a variety of parental responses. This makes studying the problems of parents in the care of infants during the first months of life a relevant issue. Objective: to determine the socio-demographic characteristics of parents with a one month old child and to identify the difficulties parents face in caring for their infants during the first months of life. Materials and methods: cross-sectional study, experimental, descriptive, with a non probabilistic sample of 88 parents. A questionnaire was applied in two parts, the first consisting of a socio-demographic and obstetrical configuration. The second part was applied to determine the difficulties of parents in the care of infants during the first months of life. Results and discussion: the study identifies and describes the difficulties experienced by parents in the care of newborns. It is essential to know the problems of parents during the first months of life of their infants in order to promote better adaptation strategies for their new roles and to develop better parenting skills.
