Treball final de carrera. Consisteix en la creació d'un portal web que permet als usuaris que s'hi registrin gestionar la seva economia domèstica a base de registrar i classificar les seves despeses i ingressos

Las narrativas del trabajo (versión 0.2)

Este texto recrea en forma de juego la idea de que la mujer se encuentra en un continuo de vida-trabajo. No existe "el ángel del hogar" y, por lo tanto, no hay representación de las tareas domésticas, pero éstas son un continuo que estructuran la vida de "b", ya que exigen un constante cuidado y orden. La teórica independencia de la mujer respecto a lo doméstico y el ser autónoma le han hecho adoptar el trabajo como forma de vida. Esta contribución cuestiona el concepto de trabajo y pone en evidencia las carencias de los términos "flexibilidad", "autonomía", "individualidad", etc.

El crèdit a la Catalunya dels segles XVI i XVII ; un estat de qüestió

Aquest treball és un recull de les principals aportacions que diferents autors realitzen en torn del crèdit durant l’alta edat moderna a Catalunya, en especial al món agrari. Aquests són dos segles d’endeutament creixent on diferents despeses que durant els segles anteriors estaven previstes per l’economia familiar esdevenen motiu de crisis. Una característica clau d’aquest període també és la creixent diferenciació social i els canvis en el model productiu pagès que aquest procés va comportar.

The economic relevance of climate variables in agriculture: The case of Spain

We estimate the impact of the different climate variables on the value of Spanish farmland. We distinguish between irrigated and non-irrigated lands and use data on temperature, precipitations, physical and socioeconomic characteristics to measure these effects on farm prices and in the number of hectares of farmland. We conclude presenting the main results of our analysis, region by region, and examining the policies that could be more effective to prevent undesired effects.

Memòria justificativa del treball realitzat durant l'estada a la University of California at Los Angeles (UCLA)

Projecte de recerca elaborat a partir d’una estada a la Graduate School of Education and Information Studies (GSEIS) de la University of California at Los Angeles (UCLA), Estats Units, entre gener i juny del 2007. En el context d’elaboració d’una futura tesi doctoral sobre la metodologia comunicativa crítica i la interacció persona-ordinador, la intenció ha estat aprofundir des d'una perspectiva internacional. La GSEIS i la UCLA en general conta amb innumerables recursos bibliogràfics així com amb professorat de reconegut prestigi internacional en la recerca vinculada a la barreja de temes com l'educació, la inclusió i la transformació social, la Comunicació, les TIC i el disseny de la Interacció Persona Ordinador; integració de disciplines en la que es mou la meva tesi doctoral. La possibilitat d'accedir a la Young Research Library, així com l'assistència a diverses conferències relacionades amb el meu àmbit d'estudi, la celebració de diverses tutories amb professorat de la GSEIS i d'altres departaments de la UCLA, i la invitació a participar del seminari de doctorat del professor Douglas Kellner, han contribuït de forma remarcable al meu projecte amb: aportacions de la literatura internacional i nombrosos exemples de bones pràctiques de projectes vinculats al Participatory Design com a metodologia en si mateixa desvinculada del Disseny Centrat en l'Usuari, un dels aspectes centrals de la meva tesi. Amb tot això vaig poder reforçar i desenvolupar quatre dels capítols de la meva dissertació, concretament els relacionats amb el context social i metodològic, i els que presenten el disseny de la Interacció Persona ordinador des d'un enfocament general així com el que es centra en el Disseny participatiu i les seves vinculacions amb la metodologia comunicativa crítica.

Association between GIS-based exposure to urban air pollution during pregnancy and birth weight in the INMA Sabadell Cohort

Background: There is growing evidence that traffic-related air pollution reduces birth weight. Improving exposure assessment is a key issue to advance in this research area.Objective: We investigated the effect of prenatal exposure to traffic-related air pollution via geographic information system (GIS) models on birth weight in 570 newborns from the INMA (Environment and Childhood) Sabadell cohort.Methods: We estimated pregnancy and trimester-specific exposures to nitrogen dioxide and aromatic hydrocarbons [benzene, toluene, ethylbenzene, m/p-xylene, and o-xylene (BTEX)] by using temporally adjusted land-use regression (LUR) models. We built models for NO2 and BTEX using four and three 1-week measurement campaigns, respectively, at 57 locations. We assessed the relationship between prenatal air pollution exposure and birth weight with linear regression models. We performed sensitivity analyses considering time spent at home and time spent in nonresidential outdoor environments during pregnancy.Results: In the overall cohort, neither NO2 nor BTEX exposure was significantly associated with birth weight in any of the exposure periods. When considering only women who spent < 2 hr/day in nonresidential outdoor environments, the estimated reductions in birth weight associated with an interquartile range increase in BTEX exposure levels were 77 g [95% confidence interval (CI), 7–146 g] and 102 g (95% CI, 28–176 g) for exposures during the whole pregnancy and the second trimester, respectively. The effects of NO2 exposure were less clear in this subset.Conclusions: The association of BTEX with reduced birth weight underscores the negative role of vehicle exhaust pollutants in reproductive health. Time–activity patterns during pregnancy complement GIS-based models in exposure assessment.

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.

The influence of genetic and environmental factors among MDMA users in cognitive performance

This study is aimed to clarify the association between MDMA cumulative use and cognitive dysfunction, and the potential role of candidate genetic polymorphisms in explaining individual differences in the cognitive effects of MDMA. Gene polymorphisms related to reduced serotonin function, poor competency of executive control and memory consolidation systems, and high enzymatic activity linked to bioactivation of MDMA to neurotoxic metabolites may contribute to explain variations in the cognitive impact of MDMA across regular users of this drug. Sixty ecstasy polydrug users, 110 cannabis users and 93 non-drug users were assessed using cognitive measures of Verbal Memory (California Verbal Learning Test, CVLT), Visual Memory (Rey-Osterrieth Complex Figure Test, ROCFT), Semantic Fluency, and Perceptual Attention (Symbol Digit Modalities Test, SDMT). Participants were also genotyped for polymorphisms within the 5HTT, 5HTR2A, COMT, CYP2D6, BDNF, and GRIN2B genes using polymerase chain reaction and TaqMan polymerase assays. Lifetime cumulative MDMA use was significantly associated with poorer performance on visuospatial memory and perceptual attention. Heavy MDMA users (>100 tablets lifetime use) interacted with candidate gene polymorphisms in explaining individual differences in cognitive performance between MDMA users and controls. MDMA users carrying COMT val/val and SERT s/s had poorer performance than paired controls on visuospatial attention and memory, and MDMA users with CYP2D6 ultra-rapid metabolizers performed worse than controls on semantic fluency. Both MDMA lifetime use and gene-related individual differences influence cognitive dysfunction in ecstasy users.
