Social economy, youth and employment

Organizations of the Social Economy in Spain accounted for 13% of employment and 12% of GDP in 2013, according to the Spanish Confederation fo Social Economy. Also, according to various institutions and studies, the role of Social Economy has become relevant due to they represent a model promoting the creation of collective business projects with greater sustainability and potential than models of individual self-employment. However, despite all this, there are few academic studies or sectoral reports analyzing employment in this sector, especially in the case of youth employment. This study aims to fill this gap in the literature analyzing the scared available data in order to show the numbers and characteristics of youth employment in this sector. Results show the weight of youth employment in the Social Economy is higher than the economy overall.

Understandings of transnational families in debates on Migration and development

International migration sets in motion a range of significant transnational processes that connect countries and people. How migration interacts with development and how policies might promote and enhance such interactions have, since the turn of the millennium, gained attention on the international agenda. The recognition that transnational practices connect migrants and their families across sending and receiving societies forms part of this debate. The ways in which policy debate employs and understands transnational family ties nevertheless remain underexplored. This article sets out to discern the understandings of the family in two (often intermingled) debates concerned with transnational interactions: The largely state and policydriven discourse on the potential benefits of migration on economic development, and the largely academic transnational family literature focusing on issues of care and the micro-politics of gender and generation. Emphasizing the relation between diverse migration-development dynamics and specific family positions, we ask whether an analytical point of departure in respective transnational motherhood, fatherhood or childhood is linked to emphasizing certain outcomes. We conclude by sketching important strands of inclusions and exclusions of family matters in policy discourse and suggest ways to better integrate a transnational family perspective in global migration-development policy.

Anclaje, dinámicas e impactos territoriales de la cadena global de cítricos dulces en el nordeste argentino

El artículo analiza firmas insertas en circuitos globalizados de exportación de frutas frescas, así como la interfase empresas-territorios. Se focaliza en la producción argentina de cítricos dulces y particularmente en un espacio productivo, y se interesa por cómo se traduce la construcción de los circuitos globales en los espacios y actores locales. Para ello, desarrolla una tipología de empresas e indicadores de anclaje y recurre a una combinación de fuentes cuantitativas y cualitativas, con vistas a desentrañar la “caja negra” del comportamiento empresarial. Se concluye que existen diferentes grados de anclaje territorial y combinaciones variables de fijación y movilidad por parte de las empresas. La adopción de una modalidad de agricultura empresarial multilocalizada, orientada al aprovechamiento de las peculiaridades de los diferentes ambientes locales, conduce a la desarticulación de espacios en función de sus características productivas y de sus diversos contextos sociales e institucionales. De esta forma se promueve la conformación de agentes de características flexibles, transformando su reproducción en contingente.

Arteterapia en el final de la vida

El arteterapia permite una aproximación creativa biográfica particularmente valiosa en la etapa final de la vida. La persona enferma presenta múltiples necesidades – físicas, emocionales, sociales y espirituales – que solo una atención holística puede pretender abarcar, tal como lo contempla la filosofía de los cuidados paliativos. El arteterapeuta integrado en el equipo interdisciplinar contribuye a aliviar y acompañar el sufrimiento del paciente y su familia. Se presentan aquí las bases teóricas y la metodología de la intervención, así como el marco sanitario en el cual se inscribe.

Proyección y política cultural estadounidense en argentina (1928-1941)

El objetivo del artículo es analizar algunos aspectos de los orígenes de la “política cultural” estadounidense en Argentina. La atención se concentrará en el pasaje desde las declaraciones del presidente Hoover, que contribuyeron a favorecer un clima útil y propicio a la intensificación de los intercambios, a los primeros pasos concretos realizados en el periodo de la presidencia de Roosevelt. Se tratará, en particular, de individualizar las características de la cooperación establecida entre organismos estadounidenses y argentinos para favorecer la proyección cultural estadounidense en el país y el intercambio cultural entre Estados Unidos y Argentina, donde se iba intensificando la difusión de un sentimiento anti-imperialista, y que era entonces objetivo de formas de propaganda particularmente agresivas por parte de los regímenes totalitarios.

"Abhold, leid, gewillt"... ¿Son adjetivos? Estableciendo un corpus para un diccionario sintáctico alemán-español de adjetivos

Si se pretende elaborar un diccionario de adjetivos, ya sea este monolingüe o bilingüe, la primera tarea que se le impone al lexicógrafo es la de definir qué es un adjetivo, una cuestión que todavía hoy no ha sido resuelta satisfactoriamente. En alemán hay una serie de palabras que han sido descritas tradicionalmente como adjetivos en función exclusivamente predicativa, cuyo estatus como adjetivos es, sin embargo, cuestionado por algunos autores. En este artículo se trata de dilucidar si estas palabras realmente solo pueden aparecer en función predicativa, cómo se las describe en diccionarios y gramáticas y cuáles son sus principales correspondencias en español, a fin de decidir si deberían ser incluidas en un corpus destinado a la elaboración de un diccionario sintáctico de adjetivos alemán-español.

The activity of the feminist online publications: challenges for the transmission of the feminist culture in Spain

Traditionally, big media corporations have contributed to hiding the women’s movement itself, as well as its main claims and topics of discussion (Marx, Myra y Hess, 1995; Rhode, 1995; Mendes, 2011). This has led the feminist movement to develop its own media generally print publications, usually, with a very specialized character and reduced audience. This is similar to what has occurred with quality main stream media, asthese publications have had to adapt themselves to a new communicatiion context, because of the financial crisis and  technological evolution. Feminist media has found in the Internet an excellent opportunity to access citizens and communicate their messages. , In view of this scene of change and renovation,  this article offers the results of a qualitative analysis focused on the experiences of four feminist online media sites edited in Spain: Pikaramagazine.com, Proyecto-kahlo.com, Mujeresenred.net and Laindependent.cat. Besides exploring the characteristics and content of these sites, the article pays attention to the virality of their contents spread through Facebook and Twitter. The onclusion estimates their social impact, insofar as they symbolize the specialization, diversification and dialogue promoted by the Web.

Genome-wide association studies in oesophageal adenocarcinoma and Barrett's oesophagus: a large-scale meta-analysis

Background: Esophageal adenocarcinoma (EA) is one of the fastest rising cancers in western countries. Barrett’s Esophagus (BE) is the premalignant precursor of EA. However, only a subset of BE patients develop EA, which complicates the clinical management in the absence of valid predictors. Genetic risk factors for BE and EA are incompletely understood. This study aimed to identify novel genetic risk factors for BE and EA.Methods: Within an international consortium of groups involved in the genetics of BE/EA, we performed the first meta-analysis of all genome-wide association studies (GWAS) available, involving 6,167 BE patients, 4,112 EA patients, and 17,159 representative controls, all of European ancestry, genotyped on Illumina high-density SNP-arrays, collected from four separate studies within North America, Europe, and Australia. Meta-analysis was conducted using the fixed-effects inverse variance-weighting approach. We used the standard genome-wide significant threshold of 5×10-8 for this study. We also conducted an association analysis following reweighting of loci using an approach that investigates annotation enrichment among the genome-wide significant loci. The entire GWAS-data set was also analyzed using bioinformatics approaches including functional annotation databases as well as gene-based and pathway-based methods in order to identify pathophysiologically relevant cellular pathways.Findings: We identified eight new associated risk loci for BE and EA, within or near the CFTR (rs17451754, P=4·8×10-10), MSRA (rs17749155, P=5·2×10-10), BLK (rs10108511, P=2·1×10-9), KHDRBS2 (rs62423175, P=3·0×10-9), TPPP/CEP72 (rs9918259, P=3·2×10-9), TMOD1 (rs7852462, P=1·5×10-8), SATB2 (rs139606545, P=2·0×10-8), and HTR3C/ABCC5 genes (rs9823696, P=1·6×10-8). A further novel risk locus at LPA (rs12207195, posteriori probability=0·925) was identified after re-weighting using significantly enriched annotations. This study thereby doubled the number of known risk loci. The strongest disease pathways identified (P<10-6) belong to muscle cell differentiation and to mesenchyme development/differentiation, which fit with current pathophysiological BE/EA concepts. To our knowledge, this study identified for the first time an EA-specific association (rs9823696, P=1·6×10-8) near HTR3C/ABCC5 which is independent of BE development (P=0·45).Interpretation: The identified disease loci and pathways reveal new insights into the etiology of BE and EA. Furthermore, the EA-specific association at HTR3C/ABCC5 may constitute a novel genetic marker for the prediction of transition from BE to EA. Mutations in CFTR, one of the new risk loci identified in this study, cause cystic fibrosis (CF), the most common recessive disorder in Europeans. Gastroesophageal reflux (GER) belongs to the phenotypic CF-spectrum and represents the main risk factor for BE/EA. Thus, the CFTR locus may trigger a common GER-mediated pathophysiology.

Effet de l’environnement alimentaire bâti autour des écoles sur les comportements d’achat alimentaire des jeunes du secondaire

Le nombre de jeunes avec un surplus de poids est en hausse au Canada (Roberts, Shields, de Groh, Aziz et Gilbert, 2012). Les conséquences négatives de cette condition sont multiples pour le jeune, actuellement et pour son avenir. La recherche visant à comprendre les raisons de cette augmentation cible, entre autres, les environnements alimentaires dont le paysage scolaire. Des restaurants rapides et des dépanneurs sont dénombrés dans l’environnement alimentaire bâti en milieu scolaire (Lalonde et Robitaille, 2014). La présence et la concentration de commerces alimentaires dans le voisinage des écoles favorisent l’achat d’aliments et de boissons par les jeunes (He, Tucker, Gilliland, Irwin, Larsen, et Hess, 2012a; Robitaille, Paquette, Cutumisu, Lalonde, Cazale, Traoré et Camirand, 2015; Seliske, Pickett, Rosu et Janssen, 2013; Virtanen, Kivimäki, Ervasti, Oksanen, Pentti, Kouvonen, Halonen, Kivimäki, Vahtera, 2015). Pourtant, le lien causal entre le paysage alimentaire scolaire et les achats des jeunes n’est pas soutenu par la littérature scientifique actuelle. À Sherbrooke, un changement dans l’environnement alimentaire bâti est survenu en 2012 suite à l’implantation de commerces alimentaires en périphérie d’une école secondaire. Ce projet était une occasion exceptionnelle de valider si la modification naturelle de la densité alimentaire autour d’une école avait un effet sur les comportements d’achat des jeunes dans cet environnement. L’objectif de ce travail de maîtrise était de mesurer le lien entre les comportements d’achat des jeunes du secondaire dans l’environnement alimentaire bâti en milieu scolaire et la densité de certains commerces alimentaires circonscrite autour de leur école. L’hypothèse émise était que les jeunes dont l’école était entourée d’une densité plus élevée de commerces alimentaires étaient plus nombreux à acheter des aliments et des boissons dans ces commerces que les autres adolescents. Pour ce faire, un questionnaire auto-administré a été rempli en classe par des élèves de trois écoles secondaires sherbrookoises. Les données obtenues ont permis de documenter les comportements d’achat de près de 3 000 jeunes en 2013. Ces comportements d’achat ont été comparés à ceux collectés dans le Portrait des jeunes sherbrookois de 4 à 17 ans en matière d’alimentation et d’activité physique et sportive réalisé en 2008 (n = 3 867) (Morin et al., 2009a). Parallèlement, une cartographie des environnements alimentaires autour de chaque école participante à chaque temps a permis de décrire les densités alimentaires scolaires. Au regard de l’environnement alimentaire bâti en milieu scolaire, peu de liens existent entre la prévalence d’acheteurs le midi et la densité de restaurants rapides autour des écoles, selon nos résultats. Seul l’effet défavorable d’une très forte concentration en restaurants rapides (soit plus d’une douzaine) a émergé de nos résultats. De plus, aucune tendance n’a été décelée entre l’évolution du paysage alimentaire autour des écoles entre les deux temps et les changements dans les prévalences d’acheteurs. Ainsi, les efforts fournis pour diminuer la densité alimentaire en périphérie des écoles doivent être remis en question considérant le faible effet mesuré sur les comportements d’achat des jeunes dans notre étude. En ce qui trait aux comportements d’achat des jeunes, nos résultats ont montré que seule une faible proportion de jeunes était des consommateurs dans les environnements alimentaires scolaires. En effet, moins d’un jeune sur dix a acheté un aliment ou une boisson sur l’heure du midi dans un restaurant rapide dans la semaine sondée. Cette pratique ne semblait donc pas caractériser le régime alimentaire global des jeunes et ainsi, son influence réelle sur la hausse des taux d’obésité est incertaine (Macdiarmid, Wills, Masson, Craig, Bromley et McNeill, 2015). De plus, selon nos résultats, la prévalence des acheteurs au restaurant rapide durant une semaine typique a diminué entre les deux temps. D’un autre côté, la qualité nutritive des achats dans ces commerces durant une semaine s’était améliorée entre les deux temps. Cependant, les choix moins nutritifs étaient toujours achetés par plus de jeunes que les aliments et les boissons nutritifs. Les quantités achetées à chaque visite dans un restaurant rapide étant inconnues dans notre étude, il était difficile de statuer sur l’effet réel des achats sur les prévalences d’obésité. En conclusion, il demeure essentiel d’améliorer les habitudes alimentaires des jeunes, entre autres, dans les restaurants rapides lors d’une journée scolaire (Macdiarmid et al., 2015). Par conséquent, l’offre alimentaire dans l’environnement alimentaire bâti en milieu scolaire doit être bonifiée, par exemple en collaborant avec les commerçants alimentaires déjà établis. Il faut également maintenir les efforts déployés pour améliorer l’environnement alimentaire dans l’école et élaborer des stratégies pour que les jeunes mangent à la cafétéria de l’école.

β-N-methylamino-l-alanine (BMAA) and isomers: Distribution in different food web compartments of Thau lagoon, French Mediterranean Sea

The neurotoxin BMAA (β-N-methylamino-l-alanine) and its isomer DAB (2,4-diaminobutyric acid) have been detected in seafood worldwide, including in Thau lagoon (French Mediterranean Sea). A cluster of amyotrophic lateral sclerosis (ALS), a neurodegenerative disease associated with BMAA, has also been observed in this region. Mussels, periphyton (i.e. biofilms attached to mussels) and plankton were sampled between July 2013 and October 2014, and analyzed using HILIC-MS/MS. BMAA, DAB and AEG (N-(2-aminoethyl)glycine) were found in almost all the samples of the lagoon. BMAA and DAB were present at 0.58 and 0.83, 2.6 and 3.3, 4.0 and 7.2 μg g−1 dry weight in plankton collected with nets, periphyton and mussels, respectively. Synechococcus sp., Ostreococcus tauri, Alexandrium catenella and eight species of diatoms were cultured and screened for BMAA and analogs. While Synechococcus sp., O. tauri and A. catenella did not produce BMAA under our culture conditions, four diatoms species contained both BMAA and DAB. Hence, diatoms may be a source of BMAA for mussels. Unlike other toxins produced by microalgae, BMAA and DAB were detected in significant amounts in tissues other than digestive glands in mussels.

La première année d'insertion professionnelle des nouveaux enseignants du secondaire: comment se poursuit la construction de l'identité enseignante?

Des recherches récentes (Boies, 2012; Chong et Low, 2011; Riopel, 2006; Vallerand, 2008) ont démontré que les difficultés vécues par les enseignants lors de l’insertion professionnelle sont liées à la fragilité de leur identité professionnelle. Toutefois, peu de recherches ont étudié la construction identitaire des enseignants novices au cours de la première année d’insertion, ce que cette recherche exploratoire entend faire. Afin d’appréhender le processus dans son instantanéité, six enseignants novices du secondaire, cinq femmes et un homme, ont été suivis tout au long de leur première année d’insertion. Des données qualitatives ont été recueillies à l’aide de journaux de moments (Hess, 2006) tenus régulièrement ainsi qu'une entrevue semi-dirigée en début de première année. Nos résultats décrivent l’interaction entre les différentes sous-identités des novices (Day et Kington, 2008) constitutives de leur construction identitaire en proposant trois constats, c'est-à-dire l'unicité, la nécessité et la dualité des trois sous-identités au sein de l'articulation identitaire. Cette recherche contribue à une meilleure compréhension de l’expérience de la première année d’insertion et permet de proposer des améliorations à la formation initiale ainsi qu’aux mesures de soutien à l’insertion.

High resolution mass spectrometry for quantitative analysis and untargeted screening of algal toxins in mussels and passive samplers

Measurement of marine algal toxins has traditionally focussed on shellfish monitoring while, over the last decade, passive sampling has been introduced as a complementary tool for exploratory studies. Since 2011, liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been adopted as the EU reference method (No.15/2011) for detection and quantitation of lipophilic toxins. Traditional LC-MS approaches have been based on low-resolution mass spectrometry (LRMS), however, advances in instrument platforms have led to a heightened interest in the use of high-resolution mass spectrometry (HRMS) for toxin detection. This work describes the use of HRMS in combination with passive sampling as a progressive approach to marine algal toxin surveys. Experiments focused on comparison of LRMS and HRMS for determination of a broad range of toxins in shellfish and passive samplers. Matrix effects are an important issue to address in LC-MS; therefore, this phenomenon was evaluated for mussels (Mytilus galloprovincialis) and passive samplers using LRMS (triple quadrupole) and HRMS (quadrupole time-of-flight and Orbitrap) instruments. Matrix-matched calibration solutions containing okadaic acid and dinophysistoxins, pectenotoxin, azaspiracids, yessotoxins, domoic acid, pinnatoxins, gymnodimine A and 13-desmethyl spirolide C were prepared. Similar matrix effects were observed on all instruments types. Most notably, there was ion enhancement for pectenotoxins, okadaic acid/dinophysistoxins on one hand, and ion suppression for yessotoxins on the other. Interestingly, the ion selected for quantitation of PTX2 also influenced the magnitude of matrix effects, with the sodium adduct typically exhibiting less susceptibility to matrix effects than the ammonium adduct. As expected, mussel as a biological matrix, quantitatively produced significantly more matrix effects than passive sampler extracts, irrespective of toxin. Sample dilution was demonstrated as an effective measure to reduce matrix effects for all compounds, and was found to be particularly useful for the non-targeted approach. Limits of detection and method accuracy were comparable between the systems tested, demonstrating the applicability of HRMS as an effective tool for screening and quantitative analysis. HRMS offers the advantage of untargeted analysis, meaning that datasets can be retrospectively analysed. HRMS (full scan) chromatograms of passive samplers yielded significantly less complex data sets than mussels, and were thus more easily screened for unknowns. Consequently, we recommend the use of HRMS in combination with passive sampling for studies investigating emerging or hitherto uncharacterised toxins.

Obtenção de extratos de agaricus bisporus com ergosterol para incorporação em iogurtes e procedimentos de microencapsulação

Além de ser o cogumelo mais consumido no mundo, Agaricus bisporus é um dos cogumelos mais ricos em ergosterol, representando esta molécula quase 90% da sua fração de esteróis. Vários estudos têm atribuído ao ergosterol diferentes bioatividades, incluindo efeitos hipocolesterolémicos semelhantes aos exibidos pelos fitoesteróis. Isto torna o ergosterol uma molécula interessante para ser estudada como composto nutracêutico. Assim, este trabalho teve como objetivo avaliar o potencial de utilização dos extratos de A. bisporus ricos em ergosterol na produção de bebidas lácteas funcionais. Para o efeito, foram realizados testes de incorporação do extrato e do ergosterol puro em iogurtes que se compararam com bebidas lácteas funcionais comerciais (aditivadas com fitoesteróis). As amostras de A. bisporus foram submetidas a uma extração assistida por ultrassons e os extratos obtidos (IEXT), bem como a molécula de ergosterol em diferentes concentrações (IERG1 e IERG2), foram incorporados em iogurtes, e comparadas com amostras controlo (amostras de iogurte sem aditivos) (ICN) e iogurtes comerciais contendo fitoesteróis (ICP). Todas as amostras foram analisadas imediatamente após a incorporação (T0), e após sete dias de armazenagem a 4°C (T1), em relação aos parâmetros nutricionais, atividade antioxidante e propriedades citotóxicas em linhas celulares tumorais humanas e numa cultura primária de células de fígado de porco (não tumoral) para avaliação da toxicidade. O teor de ergosterol incorporado na forma pura, ou presente nos extratos, foi monitorizado por HPLC-UV. Adicionalmente, foi realizado um estudo de microencapsulação utilizando a técnica de coacervação, tendo o quitosano e o isolado proteico de soro como materiais encapsulantes. Num ensaio preliminar determinou-se o pH conducente a um maior rendimento de encapsulação e, seguidamente, verificou-se a influência da razão proteína:quitosano (P/Q) e da temperatura utilizada, no rendimento de encapsulação (Y1), na eficiência de encapsulação (Y2) e na carga (teor de ergosterol nas microesferas) (Y3). Posteriormente, o estudo foi realizado baseando-se nas melhores condições para encapsular ergosterol, sendo também avaliadas as respostas Y1, Y2 e Y3.

Posteriormente, o estudo foi realizado baseando-se nas melhores condições para encapsular ergosterol, sendo também avaliadas as respostas Y1, Y2 e Y3. As bebidas funcionalizadas com o extrato (IEXT) e com ergosterol na mesma concentração existente no extrato (IERG1) revelaram uma atividade antioxidante similar às bebidas comerciais com fitoesteróis. No entanto, as bebidas com ergosterol na mesma concentração do extrato de A. bisporus e de fitoesteróis (IERG2) revelaram uma atividade antioxidante superior. Além disso, apenas IEXT, IERG1 e IERG2 apresentaram um aumento na atividade antioxidante de T0 para T1, com destaque para a atividade exibida por IERG2, significando que o ergosterol e os extratos foram capazes de proteger a bebida láctea da oxidação, aumentando a vida de prateleira do produto. IERG2 foi a amostra que revelou a maior citotoxicidade para as linhas celulares tumorais, enquanto as bebidas com fitoesteróis mostraram a menor atividade, sem diferenças significativas entre T0 e T1. Os estudos de microencapsulação revelaram ainda que a técnica de coacervação permite obter cápsulas de distintos tamanhos e que as condições ótimas do processo ocorrem a pH 5,5, com temperatura de 55ºC e razão P/Q de 0,5, com um menor rendimento de encapsulação, mas com uma maior carga em ergosterol. Este trabalho contribuiu para o estudo do potencial da utilização de extratos de A. bisporus com ergosterol no desenvolvimento de novas bebidas funcionais. Constituiu um primeiro passo que necessita de estudos subsequentes relacionados com a avaliação da viabilidade da sua utilização ao nível industrial e demonstração clara da sua bioatividade in vivo.

Toxin and Growth Responses of the Neurotoxic Dinoflagellate Vulcanodinium rugosum to Varying Temperature and Salinity

Vulcanodinium rugosum, a recently described species, produces pinnatoxins. The IFR-VRU-01 strain, isolated from a French Mediterranean lagoon in 2010 and identified as the causative dinoflagellate contaminating mussels in the Ingril Lagoon (French Mediterranean) with pinnatoxin-G, was grown in an enriched natural seawater medium. We tested the effect of temperature and salinity on growth, pinnatoxin-G production and chlorophyll a levels of this dinoflagellate. These factors were tested in combinations of five temperatures (15, 20, 25, 30 and 35 °C) and five salinities (20, 25, 30, 35 and 40) at an irradiance of 100 µmol photon m−2 s−1. V. rugosum can grow at temperatures and salinities ranging from 20 °C to 30 °C and 20 to 40, respectively. The optimal combination for growth (0.39 ± 0.11 d−1) was a temperature of 25 °C and a salinity of 40. Results suggest that V. rugosum is euryhaline and thermophile which could explain why this dinoflagellate develops in situ only from June to September. V. rugosum growth rate and pinnatoxin-G production were highest at temperatures ranging between 25 and 30 °C. This suggests that the dinoflagellate may give rise to extensive blooms in the coming decades caused by the climate change-related increases in temperature expected in the Mediterranean coasts.
