Explaining parental dedication to child care in Spain

The quality of the time dedicated to child care has potential positive effects on children’s life chances. However, the determinants of parental time allocation to child care remain largely unexplored, particularly in context undergoing rapid family change such as Spain. We assess two alternative explanations for differences between parents in the amount of time spent with children. The first, based in the relative resources hypothesis, links variation in time spent with children to the relative attributes (occupation, education or income) of one partner to the other. The second, derived from the social status hypothesis, suggests that variation in time spent with children is attributable to the relative social position of the pair (i.e. higher status couples spend more time with children regardless of within-couple difference).To investigate theses questions, we use a sample of adults (18-50) from the Spanish Time Use Survey (STUS) 2002-2003 (n=7,438). Limiting the analysis to adults who are married or in consensual unions, the STUS allows to assess both the quantity and quality of parental time spent with children. We find little support for the “relative resources hypothesis”. Instead, consistent with the “social status hypothesis”, we find that time spent on child care is attributable to the social position of the couple, regardless of between-parent differences in income of education.

Parental investments in children: how bargaining and educational homogamy affect time allocation

This study examines parental time investment in their children, distinguishing between developmental and non-developmental care. Our analyses centre on three influential determinants: educational background, marital homogamy, and spouses' relative bargaining power. We find that the emphasis on quality care time is correlated with parents' education, and that marital homogamy reduces couple specialization, but only among the highly educated. In line with earlier research, we identify gendered parental behaviour. The presence of boys is an important condition for fathers' time dedication, but primarly among lower educated fathers. To the extent that parental stimulation is decisive for child outcomes, our findings suggest the persistence of important inequalities. This emerges through our special attention to behavioural differences across the educational distribution among households.

Prevalence of alcohol-impaired drivers based on random breath tests in a roadside survey

Sobriety checkpoints are not usually randomly located by traffic authorities. As such, information provided by non-random alcohol tests cannot be used to infer the characteristics of the general driving population. In this paper a case study is presented in which the prevalence of alcohol-impaired driving is estimated for the general population of drivers. A stratified probabilistic sample was designed to represent vehicles circulating in non-urban areas of Catalonia (Spain), a region characterized by its complex transportation network and dense traffic around the metropolis of Barcelona. Random breath alcohol concentration tests were performed during spring 2012 on 7,596 drivers. The estimated prevalence of alcohol-impaired drivers was 1.29%, which is roughly a third of the rate obtained in non-random tests. Higher rates were found on weekends (1.90% on Saturdays, 4.29% on Sundays) and especially at night. The rate is higher for men (1.45%) than for women (0.64%) and the percentage of positive outcomes shows an increasing pattern with age. In vehicles with two occupants, the proportion of alcohol-impaired drivers is estimated at 2.62%, but when the driver was alone the rate drops to 0.84%, which might reflect the socialization of drinking habits. The results are compared with outcomes in previous surveys, showing a decreasing trend in the prevalence of alcohol-impaired drivers over time.

Parental altruism under imperfect information: Theory and evidence

Can we reconcile the predictions of the altruism model of the familywith the evidence on intervivos transfers in the US? This paper expandsthe altruism model by introducing e ?ort of the child and by relaxingthe assumption of perfect information of the parent about the labormarket opportunities of the child. First, I solve and simulate a modelof altruism under imperfect information. Second, I use cross-sectionaldata to test a prediction of the model: Are parental transfers especiallyresponsive to the income variations of children who are very attached tothe labor market? The results suggest that imperfect information accountsfor several patterns of intergenerational transfers in the US.

Modelling state dependence and feedback effects between poverty, employment and parental home emancipation among European youth

Youth is one of the phases in the life-cycle when some of the most decisivelife transitions take place. Entering the labour market or leaving parentalhome are events with important consequences for the economic well-beingof young adults. In this paper, the interrelationship between employment,residential emancipation and poverty dynamics is studied for eight Europeancountries by means of an econometric model with feedback effects. Resultsshow that youth poverty genuine state dependence is positive and highly significant.Evidence proves there is a strong causal effect between poverty andleaving home in Scandinavian countries, however, time in economic hardshipdoes not last long. In Southern Europe, instead, youth tend to leave theirparental home much later in order to avoid falling into a poverty state that ismore persistent. Past poverty has negative consequences on the likelihood ofemployment.

Adaptación psicosocial en niños adoptados internacionalmente: percepción personal y parental

Objetivo: Evaluar el nivel de adaptación psicosocial en la mediana infancia en ni nos adoptados internacionalmente en Espa na. Material y métodos: Ciento un menores adoptados internacionalmente (67% ni nas), de entre 8 y 12 a nos, y sus respectivos padres adoptivos (97 madres y 67 padres) completaron el Behavior Assessment System for Children (BASC). Se realizaron análisis descriptivos y de comparación de medias (t de Student y Anova) para examinar el efecto de las variables sexo, edad de adopción, edad actual y área de origen en las escalas y dimensiones globales del BASC para cada informante, y se efectuaron análisis de regresión lineal múltiple para conocer su valor predictivo. El acuerdo entre madres y padres se calculó mediante el coeficiente de correlación intraclase (CCI). Los porcentajes de menores en el rango normal y con sintomatología en las dimensiones globales se contrastaron con los teóricos mediante la prueba de la chi al cuadrado. Resultados: Se constata que los ni nos están en general bien adaptados, independientemente del informante. Existen diferencias adaptativas dentro de la normalidad según el área de origen,sexo y edad actual del los ni nos. El CCI presenta un intervalo entre 0,46 (satisfactorio) y 0,84 (excelente). En comparación con el grupo normativo, un mayor porcentaje de ni nos presenta desajuste escolar (24,8%; informado por los ni nos), problemas externalizados (el 27,8 y el 28,3%, informados por las madres y los padres, respectivamente) y dificultades comportamentales y adaptativas (el 28,4 y el 29,9%, respectivamente; informadas por los padres). Conclusiones: Entorno a un 25% de menores adoptados internacionalmente presenta dificultades en áreas adaptativas básicas, identificadas con claridad mediante el uso del BASC, que deben ser atendidas desde un enfoque psicológico y paidológico.

Oral tongue squamous cell carcinoma (OTSCC): alcohol and tobacco consumption versus non-consumption. A study in a Portuguese population

There has been an increase in the incidence of carcinoma of the tongue, particularly among alcohol and tobacco non-users. However, the number of studies that would allow a better understanding of etiological factors and clinical features, particularly in the Portuguese population, is very limited. This study was based on patients with squamous cell carcinoma of the anterior two thirds of the tongue that were treated at the Department of Head and Neck Surgery of the ¿Instituto Portugues de Oncologia de Lisboa - Francisco Gentil" IPOLFG) in Lisbon, Portugal, between January 1, 2001 and December 31, 2009. The patients were divided in alcohol and tobacco users and non-users in order to evaluate the differences between these 2 groups based on gender, age, tumor location, denture use, and tumor size, metastasis and stage. Of the 354 cases, 208 were users and 146 were non-users. The main location in both groups was the lateral border of the tongue. Denture use showed no significant effect in both study groups. It was possible to conclude that patients who did not drink or smoke were older and presented with smaller tumor size, lower incidence of ganglion metastasis and lower tumor stage compared with alcohol and tobacco users.

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.

Regulation of human class I alcohol dehydrogenases by bile acids

Class I alcohol dehydrogenases (ADH1s) are the rate-limiting enzymes for ethanol and vitamin A (retinol) metabolism in the liver . Because previous studies have shown that human ADH1 enzymes may participate in bile acid metabolism, we investigated whether the bile acid-activated nuclear receptor farnesoid X receptor (FXR) regulates ADH1 genes. In human hepatocytes, both the endogenous FXR ligand chenodeoxycholic acid and synthetic FXR-specific agonist GW4064 increased ADH1 mRNA, protein, and activity. Moreover, overexpression of a constitutively active form of FXR induced ADH1A and ADH1B expression, whereas silencing of FXR abolished the effects of FXR agonists on ADH1 expression and activity. Transient transfection studies and electrophoretic mobility shift assays revealed functional FXR response elements in the ADH1A and ADH1B proximal promoters, thus indicating that both genes are direct targets of FXR. These findings provide the first evidence for direct connection of bile acid signaling and alcohol metabolism.

Insulin-Like growth-factor 1 myocardial expression decreases in chronic alcohol consumption

Background Chronic alcohol ingestion may cause severe biochemical and pathophysiological derangements to skeletal muscle. Unfortunately, these alcohol-induced events may also prime skeletal muscle for worsened, delayed, or possibly incomplete repair following acute injury. As alcoholics may be at increased risk for skeletal muscle injury, our goals were to identify the effects of chronic alcohol ingestion on components of skeletal muscle regeneration. To accomplish this, age- and gender-matched C57Bl/6 mice were provided normal drinking water or water that contained 20% alcohol (v/v) for 1820 wk. Subgroups of mice were injected with a 1.2% barium chloride (BaCl2) solution into the tibialis anterior (TA) muscle to initiate degeneration and regeneration processes. Body weights and voluntary wheel running distances were recorded during the course of recovery. Muscles were harvested at 2, 7 or 14 days post-injection and assessed for markers of inflammation and oxidant stress, fiber cross-sectional areas, levels of growth and fibrotic factors, and fibrosis. Results Body weights of injured, alcohol-fed mice were reduced during the first week of recovery. These mice also ran significantly shorter distances over the two weeks following injury compared to uninjured, alcoholics. Injured TA muscles from alcohol-fed mice had increased TNFα and IL6 gene levels compared to controls 2 days after injury. Total protein oxidant stress and alterations to glutathione homeostasis were also evident at 7 and 14 days after injury. Ciliary neurotrophic factor (CNTF) induction was delayed in injured muscles from alcohol-fed mice which may explain, in part, why fiber cross-sectional area failed to normalize 14 days following injury. Gene levels of TGFβ1 were induced early following injury before normalizing in muscle from alcohol-fed mice compared to controls. However, TGFβ1 protein content was consistently elevated in injured muscle regardless of diet. Fibrosis was increased in injured, muscle from alcohol-fed mice at 7 and 14 days of recovery compared to injured controls. Conclusions Chronic alcohol ingestion appears to delay the normal regenerative response following significant skeletal muscle injury. This is evidenced by reduced cross-sectional areas of regenerated fibers, increased fibrosis, and altered temporal expression of well-described growth and fibrotic factors.

La evaluación de la efectividad del programa se realizó a través de los datos obtenidos por los participantes en sus respuestas a dos instrumentos antes y después de la intervención, el CEG y el ADCA-1. Se informa sobre los resultados obtenidos en la evaluación de la intervención, así como de sugerencias a tener en cuenta en actividades de prevención y promoción de la salud con poblaciones de educación secundaria.

Mortalidad atribuible al alcohol en Cataluña: 1994

Fundamento: El objetivo de este estudio es evaluar la contribución del consumo de alcohol a la mortalidad en Cataluña durante 1994, así como su contribución a las muertes prematuras. Métodos: En este estudio se han utilizado los datos de las causas de muerte en Cataluña durante 1994 del Servei d’Informació i Estudis de la Direcció General de Recursos Sanitaris del Departament de Sanitat I Seguretat Social de Catalunya. Las fracciones atribuibles al alcohol están basadas en las utilizadas en el estudio de la mortalidad relacionada con el alcohol en Estados Unidos en 1987. Resultados: El 5,3% de las muertes en Cataluña durante 1994 estuvieron relacionadas con el consumo de alcohol. Esta mortalidad fue del 6,5% entre los hombres y del 3,9% entre las mujeres. La categoría diagnóstica que más contribuyó al número de muertes fue la de las neoplasias malignas (29,3%). El estudio de las muertes prematuras muestra que los accidentes no intencionales son la causa más importante (52,3%). En esta categoría diagnóstica los accidentes con vehículos a motor son los principales responsables de los años potenciales de vida perdidos (APVP). La media de APVP por cada muerte atribuible al alcohol hasta la edad de 65 fue de 7,5. Conclusiones: Este estudio muestra la magnitud que tiene el alcohol como problema de salud pública en Cataluña.

Esterification of oleic acid catalayzed by an Aspergillus niger strain. Influence of water activity and alcohol concentration

Effects of water activity and 1-propanol concentration on synthesis of propyl oleate from oleic acid using Aspergillus niger cell-bound lipases in isooctane are described. A. niger produces lipases (EC 3.1.1.3) which partly bind to the mycelium during growth. Ester production was monitored for 72 hours at different 1-propanol concentrations and water activities. Aliquots were sequentially withdrawn and propyl esters were quantified using GC and methyl palmitate as an internal standard. In all assayed conditions A. niger cell-bound lipases catalysed propyl oleate synthesis, but at different degrees.

Spanish adaptation of the Expectancy Questionnaire (EQ) about alcohol effects in adolescents

Background: Alcohol-related expectancies are especially relevant in relation to alcohol consumption during adolescence. The main aim of this study was to adapt and translate into Spanish (Castilian) the Expectancy Questionnaire (EQ), and to study its psychometric properties in adolescents. Method: The sample was composed of 514 adolescents (57.20% female, mean age = 15.21; SD = .63) who completed the EQ and the alcohol consumption questionnaire AIS-UJI. Results: Confi rmatory factor analysis indicated that an eight-factor model, grouped into two general factors of positive and negative expectancies, had acceptable fi t indices. Cronbach’s alphas ranged from .75 to .96. Finally, the structural equation model showed that positive expectancies were positively related to alcohol use, whereas negative expectancies were negatively related to drinking. Conclusions: Results showed that the Spanish version of the EQ for adolescents is a valid and reliable questionnaire to measure expectancies about alcohol effects.
