Challenges and opportunities for science journalists in adopting new technologies: the case of Spain = Retos y oportunidades para los periodistas científicos en la adopción de las nuevas tecnologías: el caso de España

This paper analyses the adoption of new information and communication technologies (ICTs) by Spanish journalists specialising in science. Applying an ethnographic research model, this study was based on a wide sample of professionals, aiming to evaluate the extent by which science journalists have adopted the new media and changed the way they use information sources. In addition, interviewees were asked whether in their opinion the Web 2.0 has had an impact on the quality of the news. The integration of formats certainly implies a few issues for today’s newsrooms. Finally, with the purpose of improving the practice of science information dissemination, the authors put forward a few proposals, namely: Increasing the training of Spanish science journalists in the field of new technologies; Emphasising the accuracy of the information and the validation of sources; Rethinking the mandates and the tasks of information professionals.

Composição tecidual dos cortes da carcaça de ovinos jovens e adultos

O objetivo deste trabalho foi avaliar a composição tecidual dos cortes da carcaça de ovinos jovens e adultos. Utilizaram-se 36 animais ½ Ile de France ½ Ideal (12 cordeiros não castrados, 12 ovelhas e 12 capões). Os animais foram criados em pasto de Tifton-85 e suplementados com concentrado em 1% em relação ao peso corporal. Os cordeiros foram desmamados com aproximadamente 17±0,87 kg de peso corporal e abatidos aos 32 kg, com aproximadamente cinco meses de idade; as ovelhas e os capões foram abatidos com aproximadamente 55±1,26 kg e 60 meses de idade. O corte da carcaça com maior porcentual de músculos foi o da perna, seguido da paleta e do lombo, entre as categorias animais estudadas. Os cordeiros apresentaram o maior porcentual de ossos, nos cortes da carcaça estudados, do que os animais adultos. As gorduras subcutânea, intermuscular e total, dos cortes da carcaça, foram maiores nos animais adultos do que nos jovens, e o lombo teve maior porcentual de gordura total, seguido da paleta e da perna. Concluiu-se que as categorias animais influenciam a composição tecidual dos cortes da carcaça, e o tecido adiposo é um dos principais responsáveis por tais diferenças.

The Social Politics of Fatherhood in Spain and France: a Comparative Analysis of Parental Leave and Shared Residence

The Social Politics of Fatherhood in Spain and France: A Comparative Analysis of Parental Leave and Shared Residence The article provides a comparative analysis of policy developments on leaves for fathers and joint custody in Spain and France in the last decade. These two types of measures have been selected because they are both widely recognised as main instruments to promote new fathering styles and consequently more gender equality in the European Union. While the rhetoric of choice has been developed in both countries in relation to maternal employment and childcare, with better results in France than in Spain, it remains to be seen to what extent choice will also be extended to fathers. Keywords: Fatherhood. Family. Comparative social policy. Parental leave. Joint custody.

Predicción del rendimiento en cortes, hueso y grasa en búfalos de agua en Venezuela

Los objetivos de este estudio fueron determinar la asociación entre rasgos de la canal y el rendimiento en cortes (RCD), rendimiento en hueso y recortes de grasa en búfalos de agua, y desarrollar ecuaciones predictivas para cada variable mencionada. Se utilizaron 48 búfalos de agua (24 castrados y 24 enteros), sacrificados a los 17, 19 y 24 meses de edad con mestizaje de razas Murrah y Mediterránea. Se evaluaron las variables de la canal y del rendimiento en cortes. Se realizaron: pruebas descriptivas, análisis de correlación, residuos y de regresión lineal múltiple. En los castrados, el acabado de grasa y la circunferencia del muslo explicaron la mayor variación en RCD. El espesor de grasa y el porcentaje de grasa renal fueron las variables mayormente asociadas con el rendimiento en hueso. En los enteros, el acabado de grasa y la longitud de la canal explicaron la mayor variación en RCD. El recorte de grasa se asoció más con acabado de grasa, y el rendimiento en hueso se asoció con la conformación. Las ecuaciones obtenidas lograron explicar más del 50% de la variación del RCD. Las ecuaciones para recorte de grasa y rendimiento en hueso tuvieron mayor fuerza predictiva.

An epidemiological study of dental agenesis in a primary health area in Spain: estimated prevalence and associated factors

Objectives: To evaluate the prevalence of dental agenesis and its possible association with other developmental dental anomalies and systemic entities. Setting and Sample Population: Descriptive transversal study, for which 1518 clinical records, of patients visited by the Odontological Service of the Primary Health Centre of Cassà de la Selva (Girona-Spain) between December 2002 and February 2006 were reviewed. The data were recorded in relation to the oral and dental anomalies and the associated systemic entities, between the ones referred as concomitant in literature. Results: Values of 9.48% (7.25% excluding the third molars) for dental agenesis and 0.39% for oligodontia were obtained. The presence of dental agenesis concomitant with some other forms of oral and dental anomalies was observed. Attention must be drawn to the fact that a greater number of concomitant systemic entities were observed in those patients that presented a severe phenotypical pattern of dental agenesis. Conclusions: The results of the present study do not differ from the ones reported in studies of similar characteristics among Occidental and Spanish populations. The relationship observed between certain systemic entities and developmental dental anomalies suggest a possible common genetic etiology

A comparison of the dental status and treatment needs of older adults with and without chronic mental illness in Sevilla, Spain

Objectives: To study the dental status and treatment needs of institutionalized older adults with chronic mental illness compared to a non-psychiatric control sample. Study Design: The sample size was 100, in which 50 were psychogeriatric patients (study group; SG) classified according to DSM-IV, with a mean age of 69.6 ± 6.7 years, and 50 non-psychiatric patients (control group; CG), with a mean age of 68.3 ± 6.9 years. Clinical oral health examinations were conducted and caries were recorded clinically using the Decayed, Missing and Filled Teeth Index (DMFT). Results were analyzed statistically using the Student"s t-test or analysis of variance. Results: Caries prevalence was 58% and 62% in SG and CG, respectively. DMFT index was 28.3 ± 6.6 in SG and 21.4 ± 6.07 in CG (p < 0.01). Mean number of decayed teeth was higher in SG (3.1) compared to CG (1.8) (p=0.047). Mean number of missing teeth were 25.2 and 16.4 in SG and CG respectively (p<0.05). DMFT scores were higher in SG in all the age groups (p < 0.01). Mean number of teeth per person needing treatment was 3.4 in SG and 1.9 in CG (p= 0.037). The need for restorative dental care was significantly lower in the SG (0.8 teeth per person) than in the CG (1.7 teeth per person) (p = 0.043). Conclusions: Institutionalized psychiatric patients have significantly worse dental status and more dental treatment needs than non-psychiatric patients.
