Low temperature exposure of root system and inflorescence affected flowering and fruit set in 'Chardonnay' grapevines (Vitis vinifera)

The mechanisms by which low temperature affects flowering and fruit set of grapevines are poorly understood, as is the specific response of the grapevine root system and inflorescence to low temperature effects that reduce fruit set. This study aimed to determine the responses of the root system and inflorescence of the grapevine 'Chardonnay' to low temperature (10 degrees C) during flowering, and considered the possible mechanisms of low temperature effects on those parts. Temperature treatments of 10 degrees C or 20 degrees C were imposed to potted 'Chardonnay' grapevines in a glasshouse for up to two weeks during the early stages of flowering. When the root system alone was exposed to 10 degrees C (with the rest of the plant at 20 degrees C) during flowering, the number of attached berries and percentage fruit set were significantly reduced by 50 % than when the root system alone was exposed to 20 degrees C. Whereas, exposure of the inflorescence alone to 10 degrees C (with the rest of the plant at 20 degrees C) delayed flowering, allowed rachis to grow longer, and increased both the number of attached berries (from 22 to 62 per vine) and fruit set (from 8 % to, 20 %), than when the inflorescence alone was exposed to 20 degrees C. This study will enhance our understanding of the possible mechanisms of low temperature effects on grapevine fruit set and productivity.

La implicación del estudiante con la escuela

[Es]El objetivo de esta investigación ha sido analizar la implicación o compromiso de nuestros estudiantes con sus centros escolares. La implicación posee un componente conductual (la participación) y un componente psicológico (la identificación con el centro escolar). La muestra está compuesta por 656 alumnos de 14 colegios del País Vasco y Cataluña, divididos según diferentes tipologías de centro: 179 en pública-primaria, 151 alumnos en concertada-primaria, 203 alumnos en pública¬-secundaria y 123 alumnos en concertada-secundaria. Los resultados indican que las percepciones en las escalas de participación e identificación son más altas en los centros concertados, de primaria y con una sola línea educativa y modelo lingüístico. Así mismo hemos comprobado que existen correlaciones entre las dos dimensiones de la implicación y las variables independientes analizadas: autoconcepto y motivación académica, tipología de centro, trabajo de los profesores y el entorno familiar.

El rol de los contratos en viticulturas

[ES] A pesar de que los economistas han dedicado enorme esfuerzo a examinar la racionalidad de los contratos en agricultura, pocos estudios se han llevado a cabo en viticultura. Sin embargo, se observan diferencias contractuales en la producción de uva y vino. En el presente trabajo se analizan las estructuras contractuales actualmente utilizadas en varias regiones vitivinícolas. Independientemente de las características inherentes en los contratos, se obtiene que estos mecanismos permiten a las bodegas articular sus requisitos con respecto a la calidad de las uvas producidas por los agricultores.

Estudio taxonómico de las especies ibéricas del género Odiellus (Arachnida: Opiliones)

El género Odiellus Roewer, 1923, diagnosticable por un robusto tridente frontal y una excavación dorso-distal en el tronco del pene, alberga seis especies ibéricas. La elevada variabilidad detectada sugiere que hay más especies. En este trabajo se realiza la caracterización de las especies ibéricas, así como su estudio morfológico y morfométrico (haciendo hincapié en las del noreste ibérico), y la descripción de una nueva especie de Cataluña, usando para ello ejemplares conservados en la colección del Departamento de Zoología y Biología Celular Animal de la UPV/EHU, así como ejemplares capturados durante una campaña en el Macizo del Garraf entre el 1 y el 3 de noviembre del 2012. Los resultados muestran que las variables morfométricas estudiadas influyen de manera desigual en la varianza muestral, lo cual puede ser útil en futuros estudios a la hora de decidir distintos caracteres diagnósticos para cada una de las especies de Odiellus ibéricos.

Development and application of a high resolution liquid chromatographic method for the analysis of complex pigment distributions

Ternary and binary gradient systems have been developed for the high-performance liquid chromatographic analysis of complex pigment distributions typical of natural samples. Improved chromatographic resolution reveals significantly more pigment components in extracts from a sediment (Priest Pot, Cumbria, UK), a microbial mat (les Salines de la Trinital, South Catalonia, Spain) and a culture (C. phaeobacteroides) including novel bacteriochlorophyll derivatives. The methods developed are directly suited to LC–MS analysis and the automated acquisition of MS/MS data for pigments.

Factores determinantes del uso de Internet en la comercialización del aceite de oliva. Análisis del sector en Cataluña

Las cooperativas son entidades con una gran presencia económica y social en España, y tienen una gran influencia en la economía rural de las zonas donde están ubicadas. El principal objetivo del presente trabajo es el análisis del uso de las nuevas tecnologías por parte de las cooperativas agroalimentarias, centrándose en las productoras de aceite de oliva para determinar los principales factores que condicionan su comportamiento en la Red. En el presente estudio se analizan sus sitios web y se determina qué tipo de información aporta, tanto datos generales como datos de comercialización. A partir de los resultados obtenidos, se busca la relación que pueda existir entre el tamaño de la cooperativa, su actividad exportadora o la actividad de comercio electrónico con la presencia online, mediante una regresión logística. De esta manera podremos conocer si realmente la implantación de nuevas tecnologías en las cooperativas permite desarrollar una óptima actividad económica.

International on-line reciprocal peer tutoring to promote modern language development in primary schools

The paper reports data from an on-line peer tutoring project. In the project 78, 9–12-year-old students from Scotland and Catalonia peer tutored each other in English and Spanish via a managed on-line envi- ronment. Significant gains in first language (Catalonian pupils) modern language (Scottish pupils) and attitudes towards modern languages (both Catalonian and Scottish pupils) were reported for the exper- imental group as compared to the control group. Results indicated that pupils tutored each other in using Piagetian techniques of error correction during the project. Error correction provided by tutors to tutees focussed on morph syntaxys, more specifically the correction of verbs. Peer support provided via the on- line environment was predominantly based on the tutor giving the right answer to the tutee. High rates of impact on tutee corrected messages were observed. The implications for peer tutoring initiative taking place via on-line environments are discussed. Implications for policy and practice are explored

Tutoría entre iguales recíproca y virtual para la mejora de habilidades lingüísticas en español e inglés

This paper reports data from an on-line peer tutoring project, the objective being the learning and improvement of the Spanish and English language. Pupils aged between 9 and 12 years old from Scotland and Catalonia were paired for the purpose of each pupil acting as a tutor of their own language within his or her pair. The aim was to improve the knowledge and use of their own language (by correcting their tutee) as well as the modern language (through the help of their tutor) acting as tutors and also as a tutees. The research combines a quasi-experimental design, using control groups, and in depth analysis of the process throughout the exchanges (texts and corrections) and interviews with the subjects. The results show that the degree of help offered by the tutors appears to be a very relevant factor when assessing the improvement detected in the linguistic abilities. © 2010 Fundación Infancia y Aprendizaje.

Italian Canzone d'autore and Greek Entechno tragoudi: a comparative overview

‘Canzone d’autore’ is the name that a vast community of Italian music critics, authors, per-formers, producers agreed upon in the mid-1970s, to describe the Italian singer-songwriter genre. Singer-songwriters, who had been missing from Italian popular music – with very few exceptions – until the late 1950s, had become increasingly popular after 1958, and were dubbed ‘cantautori’ in 1960. The term, which propagated to Spain, Catalonia, and Latin Amer-ica, is still in use, but ‘canzone d’autore’ superseded it as a genre label, highlighting the con-nections between authorship and artistic value, implied in the already established notion of ‘Cinéma d’auteur’ from which it was derived.

The expression ‘entechno laiko tragoudi’ (‘art-folk song’) was coined in Greece by Mikis The-odorakis in the 1950s, to describe a new music genre combining the urban-folk musical idi-om with lyrics coming from high-art poetry. Although the origins of the genre are tied to the work of composers like Theodorakis and Hatzidakis who did not perform as singers, from the 1970s onwards entechno became the privileged field of new generations of Greek singer-songwriters. Dropping ‘laiko’ (folk) from its label, entechno expanded its musical influences outside the urban-folk repertory and transformed into the more all-encompassing contempo-rary ‘art song’.

Prevalência da C.trachomatis entre homens que fazem sexo com homens (HSH) que frequentam um centro clínico comunitário alternativo em Barcelona

RESUMO - Enquadramento: A infeção por Chlamydia trachomatis (CT) é considerada um grave problema de Saúde Pública. É causa de infeções sintomáticas tanto no homem como na mulher, bem como, de infeções assintomáticas que podem ter consequências muito graves a longo prazo. A presença de CT sem tratamento aumenta o risco de transmissão do vírus da imunodeficiência humana. Existem vários estudos publicados de prevalência da CT por todo o mundo, no entanto, estudos de prevalência da CT em populações assintomáticas, envolvendo homens que fazem sexo com homens (HSH) são raros na Europa. Assim, o presente estudo, ao estimar a prevalência e ao descrever as caraterísticas epidemiológicas e de conduta dos HSH, pretende contribuir para o plano de ação contra as IST´s e VIH na Catalunha, através de estratégias concretas para deteção e prevenção da CT. Métodos: Trata-se de um estudo observacional, transversal de prevalência da CT em HSH utentes de um serviço comunitário em Barcelona, com recurso a técnicas de diagnóstico de biologia molecular e a um questionário. Durante Março e Junho de 2015, foram recrutados 200 voluntários de um serviço comunitário em Barcelona que foram testados para CT e NG em três locais anatómicos através de uma PCR em tempo real utilizando o ensaio Anyplex™ CT/NG Real-time Detection. Resultados: O presente estudo permitiu uma caraterização da situação atual quanto á prevalência e aos fatores de risco associados á infeção por CT em HSH. A prevalência nesta população específica foi de 12,6% e os fatores risco associados foram o facto de serem VIH e praticarem sexo anal insertivo/recetivo com parceiro estável. Conclusões: Os resultados obtidos reforçam a necessidade do desenvolvimento de estratégias adequadas de controlo e prevenção da CT nesta população de risco, tais como: rastreios frequentes e tratamento dos casos positivos para quebrar a cadeia de transmissão, promoção da saúde, educação e notificação dos parceiros sexuais. Também demonstram a importância destes rastreios nos três locais anatómicos: uretra, reto e faringe.
