Contribución al conocimiento del polen y de las semillas del género Spergularia en Andalucía occidental

Se estudia al microscopio óptico y al microscopio electrónico de barrido el polen y las semillas de los nueve taxones del género Spergularia representados en Andalucía occidental. El polen resulta ser variable en tamaño y morfología, por lo que su interés taxonómico es sólo relativo si se compara con el de las semillas, que constituyen un carácter útil para la separación de taxones. Se elabora una clave dicotómica para la separación de las especies en función de los caracteres estudiados.

Dificultades y originalidad del género Hieracium en España

Se presentan parte de los estudios realizados con la inestimable ayuda de B. de RETZ en los herbarios P, DC y JACA. Esperamos despertar el interés de los botánicos españoles, esbozar también el área de algunos taxa españoles (H. castellanum, H. baeticum, H. lanigerum, H. granatense, etc.) para facilitar su búsqueda.Conviene seguir utilizando la nomenclatura de K.H. Zahn y lo razonamos bajo un aspecto utilitario y por la costumbre ya establecida al describir apomictos similares.

Réflexions sur l'appauvrissement des syntaxons aux limites chorologiques des unités phytosociologiques supérieurs et quelques-unes de leurs consequences

Con la ayuda de algunos ejemplos, se estudia el comportamiento de los sintáxones en los límites corológicos de las unidades fitosociológicas superiores; se muestra que, a medida que nos alejamos de su centro de gravedad, esas unidades pierden poco a poco sus especies y que, en sus límites corológicos, no quedan más especies características de unidades superiores para definir las comunidades. Se evocan entonces algunas consecuencias de esas observaciones: noción de combinación específica original, interpretación fitosociológica de los sintáxones, nomenclatura fitosociológica.

Effect of supplementation silage ("Festuca dolichophylla, Avena sativa and Vicia sativa") on weight gain and mortality in adult alpacas ("Vicugna pacos")

This study was conducted in order to evaluate the effect of supplementation with silage (Festuca dolichophylla, Avena sativa and Vicia sativa) on weight gain and mortality in adult alpacas, during the months of dry season (June to August) in Huancavelica region. 300 female alpacas 3 and 4 years of age (physiological state: pregnant) were used, which were assigned to the following treatments: SP, grazing only PSE15, grazing plus supplementation of 1.5 kg of silage. Alpacas were supplemented once daily. In each alpaca they were recorded live weight at the beginning and end of the experiment. The weight gain was -0.02 y 2.05 kg for SP and PSE15 respectively (p <0.001) treatments. Mortality was 5.3% and 2.7% for SP and PSE15 respectively (p=0.073) treatments. It can be concluded under the conditions of this trial silage supplementation has effect on weight gain and maybe also on mortality in alpacas.

Estucoqueratosis. A propósito de un caso

La estucoqueratosis es una patología dérmica que cursa con tumoraciones queratósicas asintomáticas, benignas, blanco-grisáceas y de pequeño tamaño. Éstas suelen localizarse en las extremidades (especialmente en las inferiores) en torno al tobillo. Su etiología es desconocida y su diagnóstico se realiza mediante una correcta anamnesis y exploración física ya que la morfología, localización y edad de presentación son claves para poder establecer un diagnóstico diferencial con otras afecciones aunque en caso necesario también se puede recurrir a la biopsia. Constituye una entidad clínica con especial interés podológico dada su frecuente aparición en las extremidades inferiores, de ahí la necesidad de conocerla y de saber realizar un correcto diagnóstico diferencial. Presentamos el caso de un varón de 45 años sin antecedentes dermatológicos que presenta estucoqueratosis en la extremidad inferior y que acude al Servicio de Dermatología del Hospital Naval de Ferrol.

Social Work and theatre: considering intersections

Theatre is a cultural and artistic form that involves a process of communication between creators and is received in a space and time located in the public sphere, which has meant that, over the centuries, it has acted as a space for expression, exchange and debate regarding all manner of ideas, causes and struggles. Implicit within this process are processes of expression, creation and reception, by way of which people demonstrate, analyse and question ways of seeing and understanding life, and ways of being and existing in the world. This gives rise to educational, cultural, social and political potential, which has been endorsed in numerous studies and investigations. In this work, in which theoretical orientation is established through a review of the relevant literature, we consider different intersections that occur between theatre and social work in order to also show that dramatic and theatrical expression offers substantive methodologies for achieving some objectives of social work, particularly in areas such as critical literacy, reflexivity and recognition, awareness raising, social participation, personal and/or community development, ownership of cultural capital and access to personal and social wellbeing.

The trade unions membership dynamics and union members’ trajectories

This text presents an analysis of aggregated membership’s dynamics for Spanish trade unions, using ECVT data, as well as union memberships’ trajectories, or members’ decisions about joining the organization, permanency and responsibilities, and subsequent attrition. For the analysis of trajectories we make use of information of the records of actual memberships and the record of quitting of CCOO, and of a survey-questionnaire to a sample of leavers of the same union. This study allows us to confirm a linkage between the decision and motivations to become union member, to participate in union activities, the time of permanency, and the motives to quit the organization. We also identify five types of union members’ trajectories, indicating that, far from views that assert a monolithic structure, unions are complex organizations.

Spanish Sociology and Anti-Semitism Between passed prejudice and key to civilization

There is a significant lack of sociological research in Spain about anti-Semitism. At the same time there are alarming anti-Semitic tendencies and anti-Jewish stereotypes which are above the European average. This article aims to explain this lack of sociological research about anti-Semitism in Spain. Therefore two types of explications are offered: on the one hand side some structural problems will be shown which sociology in general had since its beginnings and which complicate the understanding of anti-Semitism. Furthermore explications regarding the specific social and historic situation in Spain and of Spanish sociology in particular will be exposed. It will be shown that for its rationalistic character and with the exception of very few authors – who are considered marginalized for practical research – sociology in general has had enormous problems in understanding anti-Semitism. The specific historic situation, Francoism, the dispute about the historic memory and the delayed institutionalisation of sociology could also explain the lack of sociological interest in the topic especially in Spain. The article shows that the study of anti-Semitism is not only relevant for struggling against this burden of society in many of its variants. Furthermore, thinking about anti-Semitism can help sociology to recognise its own epistemological problems. It can serve to criticise and improve instruments of sociological research by showing the limitations of the sociological approach and to uncover the importance of interdisciplinary research for understanding specific social phenomena. In that sense, anti-Semitism, far from being a marginal subject, can be considered a key topic in the process of civilisation and it can help us to decipher the contemporary Spanish society.

The “re-socialization” of Gypsy women in the literacy courses aimed to the recipients of the Social Integration Revenue Policy of the Region of Madrid

This article studies the gender values that are promoted both in the literacy courses for gypsy women beneficiaries of the Social Integration Revenue Policy of the Region of Madrid and in the events that are organized for this group by public institutions and NGOs. The process of “socialization” that occurs in the educative groups for Gypsy women is focused on constructing an image of what it is to be a “Gypsy modern woman”. Through multiple mechanisms and discursive techniques a specific conception of gender equality is transmitted in these educative spaces. In addition to this, Gypsy women are continually urged to assume certain values and social practices (of gender identity, of "citizenship", of parenting, etc..), while an archetype of "Gypsy Woman" which condenses powerful stereotypes and prejudices about the "Gypsy culture" and the gender relations characteristics of this group is constructed.
