Hacia una reformulación sistémica del “Síndrome de Alienación Parental”. Estudio de un caso.

El objetivo del presente estudio es realizar una lectura de una situación de alienación parental en un divorcio conflictivo desde un enfoque sistémico-relacional, respondiendo a la falta de modelos de intervención para dicha casuística y considerando poco holístico el planteamiento defendido bajo la categoría Síndrome de Alienación Parental (SAP), descrita por Gardner el año 1985. Se analizan con metodología cualitativa cinco sesiones de psicoterapia de una familia de tres miembros derivada judicialmente por el rechazo de la hija a mantener contacto con la madre. Atendiendo a sus respectivas narrativas en relación a la pareja, los resultados muestran una mitología compartida en el pasado y una ruptura de la misma, en el caso de la madre. Se observa una precaria gestión del cambio, así como un conflicto comunicacional que impide desarrollar nuevas estrategias narrativas tras la separación. Los resultados permiten apoyar la apertura de líneas de investigación que contribuyan a una reformulación del SAP desde una perspectiva más profunda que aprehenda la complejidad de lo llamamos las Prácticas Alienadoras Familiares (PAF).

Transitions in partnership and parental status, gender, and political and civic participation

Participation research has documented the effect of partner and parenthood status, thereby ignoring the dynamic aspect of status changes. Based on theoretical insights on changes in political resources and interest, this study looks at partnership and parenthood as dynamic characteristics. Using data from the Swiss Household Panel (SHP), it examines to what extent important life-cycle transitions in partnership and parental status influence various forms of political and civic participation and whether they affect men and women's participation differently. Our regression analyses reveal that particularly the entry into separation or divorce is a main key point driving change in political and civic participation. Its effect is also highly gendered. Following separation, women participate less in voting, whereas men's participation rates are not affected in a negative way. Separation even increases men's level of anticipated activism. Children entering or leaving the household do not seem to represent key points of change in political and civic participation of the couple. Yet, the transition to having school-aged children significantly increases some types of participation, at least for women.

The human Ia-associated invariant chain is synthesized in Ia-negative B cell variants and is not expressed on the cell surface of both Ia-negative and Ia-positive parental cells.

The expression of Ia-associated human Invariant (In) chain glycoproteins was studied in the Raji B cells as well as in their RJ 2.2.5 Ia-negative derived variant cells by using a specific rabbit anti-human In chain antiserum. Two-dimensional gel electrophoresis of immunoprecipitates from either biosynthetically labeled or surface labeled cells were analyzed. In addition, flow microfluorometric analysis of stained cells was performed. The results indicate that the In chain is constitutively produced in the Ia-negative B cell variant. Moreover, it appears that several forms of In chain-related molecules, with different charges and distinct m.w. are equally expressed in Ia-positive and Ia-negative B cells. Finally, no evidence could be obtained that the In molecular family was expressed on the cell surface of Ia-positive Raji and Ia-negative RJ 2.2.5 cells.

A longitudinal study of environmental tobacco smoke exposure in children: parental self reports versus age dependent biomarkers

Background: Awareness of the negative effects of smoking on children's health prompted a decrease in the self-reporting of parental tobacco use in periodic surveys from most industrialized countries. Our aim is to assess changes between ETS exposure at the end of pregnancy and at 4 years of age determined by the parents' self-report and measurement of cotinine in age related biological matrices.Methods: The prospective birth cohort included 487 infants from Barcelona city (Spain). Mothers were asked about maternal and household smoking habit. Cord serum and children's urinary cotinine were analyzed in duplicate using a double antibody radioimmunoassay. Results: At 4 years of age, the median urinary cotinine level in children increased 1.4 or 3.5 times when father or mother smoked, respectively. Cotinine levels in children's urine statistically differentiated children from smoking mothers (Geometric Mean (GM) 19.7 ng/ml; 95% CI 16.83–23.01) and exposed homes (GM 7.1 ng/ml; 95% CI 5.61–8.99) compared with non-exposed homes (GM 4.5 ng/ml; 95% CI 3.71–5.48). Maternal self-reported ETS exposure in homes declined in the four year span between the two time periods from 42.2% to 31.0% (p < 0.01). Nevertheless, most of the children considered non-exposed by their mothers had detectable levels of cotinine above 1 ng/mL in their urine.Conclusion: We concluded that cotinine levels determined in cord blood and urine, respectively, were useful for categorizing the children exposed to smoking and showed that a certain increase in ETS exposure during the 4-year follow-up period occurred.

Parental care time in four European countries: comparing types and contexts

The intensity of parental investments in child care time is expected to vary across families with different norms and time-constraints. Additionally, it should also differ across countries, since the abilities of parents to harmonize family and work vary by national context. In our opinion, however, this question remains inconclusive for two main reasons: 1) only some countries have been studied from a comparative approach; 2) previous studies have not paid enough attention to the analysis of how the conditional effects of education and employment affect parental investments.In this paper we used nationally representative time-use data from Denmark, Flanders, Spain and the United Kingdom (N=4,031) to explore how employment and education predict variations in child care time. IN Britain and Spain employment has a strong negative effect on fathers’ child care, but a weaker one in Flanders and particularly in Denmark. In contrast, maternal employment has a strong negative impact in all four countries. Education increases child care time significantly only among Spanish mothers and fathers, as well as British mothers. Nonetheless, we find that college-educated mothers under similar time-constraints increase substantially their expected child care time in Britain, Flanders and Spain; for fathers we find a more mixed picture. Routine child care activities are more sensitive to both maternal and paternal employment than interactive child care activities. Finally, we observe that working a public sector job generally increases a total time allocated to parental care, controlling for several demographic and socioeconomic variables.

Who benefits from parental leave in Spain? : a life course analysis

This paper analyses the extent to which individual and workplacecharacteristics and regional policies influence the use and duration ofparental leave in Spain. The research is based on a sample of 125,165people, and 6,959 parental leaves stemming from the ‘Sample ofWorking Life Histories’ (SWLH), 2006. The SWLH consists of administrative register data which include information from threedifferent sources: Social Security, Municipality and Income TaxRegisters. We adopt a simultaneous equations approach to analyse theuse (logistic regression) and duration (event history analysis) ofparental leave, which allows us to control for endogeneity and censoredobservations. We argue that the Spanish parental leave scheme increases gender and social inequalities insofar as reinforces genderrole specialization, and only encourages the reconciling of work andfamily life among workers with a good position in the labour market(educated employees with high and stable working status).

Productivities, preferences, and parental child care

We study the interplay of preferences and market productivities on parenting, and show the preferences, when identified, provide a better explanation of caring decisions than has, so far, been demonstrated in the literature. We qualify the standard finding the parental education in a key determinant of care by showing important interaction effects with marital homogamy. We find that homogamy has opposite effects on child care and couple specialization for high and low educated parents. Identification has been made possible by a unique couple-based time diary study for Denmark

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.

Apoyo a pantallas periféricas multiusuario: detección de presencias y gestión de la interacción

En este proyecto se han implementado dos sistemas: un sistema de gestión ytratamiento de la interacción multiusuario y un sistema de input mediante WebCam para lalocalización de usuarios, el cual se comunica con el sistema de gestión a través de XML. Se ha intentado conseguir un nivel de abstracción elevado de cara a que los futuros sistemas de interacción puedan añadir las funcionalidades implementadas para este proyecto.La idea nace de la limitación vigente de los sistemas interactivos que utilizan pantallasmultitouch ya que no existe ningún sistema que gestione a los múltiples usuarios que puedan interactuar al mismo tiempo en ellas. Se ha analizado el sistema de Vogel, en el cual se han intentado mejorar y solucionar ciertos aspectos de la interacción multiusuario.Se han diseñado e implementado dos métodos para tratar la gestión de la interacciónmultiusuario: sistema de elementos interactivos instanciables así como un sistema de cola (queue) dentro de los propios elementos interactivos. Todo ello basado en la idea de las áreasde interacción de los usuarios la cual es posible gracias al sistema de detección de presencias.Así pues, a través de este proyecto final de carrera se quiere mostrar que la interacciónmultiusuario en los sistemas interactivos periféricos puede gestionarse a través de diferentes métodos y de este modo mejorar la experiencia de los usuarios durante todo el proceso de interacción.

Diseño e implementación de 4SPPIces Tool: Una aplicación web para dar apoyo a la creación de actividades educativas colaborativas en entornos mezclados

La introducción de dispositivos tecnológicos como PDAs, móviles o portátiles, en la educación ofrece nuevas oportunidades para el aprendizaje. El uso apropiado de estas herramientas abre la posibilidad a un abanico de escenarios educativos colaborativos que no serían posibles sin la tecnología. Sin embargo, uno de los problemas principales que dificulta la adopción de estos dispositivos en entornos educativos reales es el comprender cómo aplicarlos de forma adecuada y beneficiosa para cubrir los objetivos de aprendizaje esperados. Para ello es necesario establecer vínculos entre educadores y tecnólogos para que este tipo de escenarios se puedan llevar a cabo. Por un lado, los educadores tienen conocimientos sobre prácticas educativas y, por otro lado, los tecnólogos pueden aportar con sus conocimientos acerca de las oportunidades que las tecnologías ofrecen. 4SPPIces es un modelo conceptual que tiene como objetivo establecer este puente entre las dos comunidades. Concretamente, se trata de un modelo que propone 4 factores interrelacionados que deben considerarse en el diseño de experiencias educativas colaborativas que combinen actividades dentro y fuera del aula: (1) el método pedagógico (Pedagiocal Method), (2) los participantes (Participants), (3) el espacio (Space) y (4) el historial (History). El objetivo de este proyecto es desarrollar una aplicación web para que educadores y tecnólogos colaboren en el diseño de escenarios basados en este modelo. Concretamente, este trabajo presenta el proceso de desarrollo de la aplicación así como algunas pruebas con usuarios para analizar la usabilidad y utilidad del sistema.

Influence d'une hospitalisation prénatale sur les facteurs de stress parentaux lors d'une naissance prématurée [Influence of prenatal hospitalization on parental stressful experience in the case of a premature birth].

OBJECTIVES: To investigate the influence of prenatal hospitalization before a premature birth, on the parental stressful experience, parental symptoms of post-traumatic stress and quality of parent-infant interaction during the hospitalization in neonatology. POPULATION AND METHODS: Population: 51 preterm infants born and 25 full term infants control. Four groups: controls, premature without prenatal hospitalization, premature with a short (<8 days) prenatal hospitalization and premature with a long (≥8 days) prenatal hospitalization. Instruments: the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS: NICU, Miles et al., 1993 [14]) and the Perinatal PTSD Questionnaire (PPQ, Quinnell and Hynan, 1999 [16]). RESULTS: When prenatal hospitalization of the mother occurred, parents acknowledged increased stress induced by the environmental factors during the infant's hospitalization. Furthermore, mothers from the group with a short prenatal hospitalization presented significantly more symptoms of post-traumatic stress. Parents presenting more symptoms of post-traumatic stress describe a significantly more difficult interaction with their infant in neonatology. CONCLUSION: This study highlights the necessity to deliver special care to women hospitalized shortly (<8 days) prior to the delivery of their premature baby. This group is at high risk of presenting post-traumatic stress symptoms, which could have a negative impact on the quality of parent-infant interactions.
