Modelo formativo y competencias transversales: una propuesta para el Grado en Educación Social

El objeto de esta comunicación es presentar el modelo formativo de los estudios de Grado de la Facultad de Educación Social y Trabajo Social Pere Tarrés de la Universidad Ramón Llull, una vez se han desplegado los tres primeros cursos de las titulaciones de Grado. Pretendemos dar a conocer las competencias transversales comunes en todas las asignaturas así como las metodologías y las actividades utilizadas para facilitar el proceso de aprendizaje de los estudiantes. Queremos constatar, por un lado, que nuestra propuesta avala la integración del nuevo modelo educativo, recogido en el Plan Bolonia, donde la actividad del estudiante es uno de los ejes centrales de su proceso formativo y, por el otro, que nos permita dar un salto cualitativo en la formación que ofrecemos a los futuros profesionales de la acción social. Pretendemos garantizar la coherencia entre los contenidos de las asignaturas que forman una misma materia y los niveles de consecución de las competencias a lo largo del período de formación. Esto implica una tarea de coordinación y de trabajo en equipo entre los profesores que garantice la consecución de los contenidos evitando vacíos o solapamientos entre asignaturas.

Menores, educación y conflicto armado: un análisis desde la realidad africana 15 años después del Informe Machel

Si bien en los últimos años África Subsahariana ha registrado un notable descenso del número de conflictos armados, un buen número de países sigue padeciendo las consecuencias de la violencia armada, especialmente algunos contextos como el de la República Democrática del Congo, la región de Darfur (oeste de Sudán) o Somalia, por citar algunos ejemplos. Tal y como desde el ámbito institucional (Naciones Unidas u ONG) o el académico llevan señalando desde hace varios años, la principal víctima de la violencia suele ser la población civil, principalmente los menores y las mujeres. El presente artículo tiene como objetivo analizar el impacto que los conflictos armados africanos tienen en la infancia y en aspectos tan importantes como su educación. Este objeto de estudio cuenta en los últimos años con un importante referente como fue la publicación en el año 1996 del denominado «Informe Machel». Quince años después de la aparición de este documento, resulta de interés hacer un pequeño balance sobre algunos de los avances, déficits y principales retos de la protección de los menores en conflictos armados.

Goal recognition over POMDPs: inferring the intention of a POMDP agent

Plan recognition is the problem of inferring the goals and plans of an agent from partial observations of her behavior. Recently, it has been shown that the problem can be formulated and solved usingplanners, reducing plan recognition to plan generation.In this work, we extend this model-basedapproach to plan recognition to the POMDP setting, where actions are stochastic and states are partially observable. The task is to infer a probability distribution over the possible goals of an agent whose behavior results from a POMDP model. The POMDP model is shared between agent and observer except for the true goal of the agent that is hidden to the observer. The observations are action sequences O that may contain gaps as some or even most of the actions done by the agent may not be observed. We show that the posterior goal distribution P(GjO) can be computed from the value function VG(b) over beliefs b generated by the POMDPplanner for each possible goal G. Some extensionsof the basic framework are discussed, and a numberof experiments are reported.

Women's work histories in Italy: education as investment in reconciliation and legitimacy?

Within pre-enlargement Europe, Italy records one of the widest employment rate gaps between highly and poorly educated women, as well one of the largest differences in the share, among working women, of public sector employment. Building on these stylized facts and using the Longitudinal Survey of Italian Households (ILFI), we investigate the working trajectories of three cohorts of Italian women born between 1935 and 1964 and observed from their first job until they are in their forties. We use mainly, but not exclusively, event history analysis in order to identify the main factors that influence entry into and exit from paid work over the life course. Our results suggest that in the Italian context, where employment protection policies have also been used as surrogate measures to favour reconciliation between family and work, and where traditional gender norms still persist, education is so important for women's employment decisions because it represents an investment in 'reconciliation' and 'work legitimacy' over and above investment in human capital.

Temporary employment in advanced economies: drawing lessons from Spain

This study analyses the determinants of the rate of temporary employment in various OECD countries using both macro-level data drawn from the OECD and EUROSTAT databases, as well as micro-level data drawn from the 8th wave of the European Household Panel. Comparative analysis is set out to test different explanations originally formulated for the Spanish case. The evidence suggests that the overall distribution of temporary employment in advanced economies does not seem to be explicable by the characteristics of national productive structures. This evidence seems at odds with previous interpretations based on segmentation theories. As an alternative explanation, two types of supply-side factors are tested: crowding-out effects and educational gaps in the workforce. The former seems non significant, whilst the effects of the latter disappear after controlling for the levels of institutional protection in standard employment during the 1980s. Multivariate analysis shows that only this latter institutional variable, together with the degree of coordinated centralisation of the collective bargaining system, seem to have a significant impact on the distribution of temporary employment in the countries examined. On the basis of this observation, an explanation of the very high levels of temporary employment observed in Spain is proposed. This explanation is consistent with both country-specific and comparative evidence.

La evaluación de la creatividad publicitaria en el ámbito docente. Análisis teórico y proyecto de investigación

La docencia de la creatividad publicitaria convive con diversas contradicciones y vacíos. Si esto es propio de cualquier materia de estudio, aquí se suma el peculiar curso científico tanto de la creatividad como de la publicidad, dos fenómenos de descomunal repercusión social, cultural y económica, aparentemente asequibles, pero en gran medida desconocidos.El presente trabajo indaga en la posibilidad de sistematizar la evaluación de la creatividad publicitaria y estima el valor docente de dicha sistematización. En una primera fase se exploran los ámbitos de referencia que afectan al tópico, así comolas conexiones que establecen entre ellos, en la esfera académica y profesional. A continuación se orientan y discuten los hallazgos de la prospección, se formula una hipótesis y se diseña una investigación que conduzca a validarla o refutarla.

Productivity and the welfare of nations

We show that the welfare of a representative consumer can be related to observable aggregatedata. To a first order, the change in welfare is summarized by (the present value of) the Solowproductivity residual and by the growth rate of the capital stock per capita. We also show thatproductivity and the capital stock suffice to calculate differences in welfare across countries, withboth variables computed as log level deviations from a reference country. These results hold forarbitrary production technology, regardless of the degree of product market competition, and applyto open economies as well if TFP is constructed using absorption rather than GDP as the measureof output. They require that TFP be constructed using prices and quantities as perceived byconsumers. Thus, factor shares need to be calculated using after-tax wages and rental rates, andwill typically sum to less than one. We apply these results to calculate welfare gaps and growthrates in a sample of developed countries for which high-quality TFP and capital data are available.We find that under realistic scenarios the United Kingdom and Spain had the highest growth ratesof welfare over our sample period of 1985-2005, but the United States had the highest level ofwelfare.

Institutional constraints on organizations: The case of Spanish car dealerships

We study the effect of organizational choice and institutions on the performance ofSpanish car dealerships. Using outlet-level data from 1994, we find that verticallyintegrateddealerships showed substantially lower labor productivity, higher labor costs andlower profitability than franchised ones. Despite these gaps in performance, no verticallyintegratedoutlet was separated until 1994, yet the few outlets that were eventuallyseparated systematically improved their performance. We argue that the conversion ofintegrated outlets into franchised ones involved significant transaction costs, due to aninstitutional environment favoring permanent, highly-unionized employment relations. Inline with this argument, we find that the observed separations occurred in distributionnetworks that underwent marked reductions in worker unionization rates, following thelegalization of temporary labor contracts.

Public and private saving and investment

We decompose aggregate saving and investment into its publicand private components and then document a variety of ``stylized facts''associated with saving and investment rates for a sample of15 countries over the period 1975--1989. In order to seewhether these empirical relationships are consistent with aworld of perfect capital mobility we develop a multi--countrymodel with free trade in a riskfree bond and calibrate it tothe fifteen OECD countries. We pay special attential tomodeling the fiscal policy rules. The model performsremarkably well in accounting for a wide variety of timeseries relationships. Nonetheless the model is not able to capture the crosssectional aspect of the data. In particular, the model cannot accountfor both the large cross country correlation between aggregate saving and investmentrates and the very negative cross country relationship between the public andprivate saving minus investment gaps.

Serie estratigráfica de Liásico de la provincia de Girona

From several small stratigraphic sections, we have reconstituted the Liassic interval of the Girona Province (NE Spain). We have been able to identify paleontologically the Carixian (Jamesoni, Ibex, and perhaps, Davoei zones), the Lower Domerian (Stockesi zone), and the Middle Toarcian (possibily Variabilis zone, as well as Thouarsense and Insigne zones). The Lower Toarcian (Serpentinus zone) is represented by fossil remains no ‘in situ’. The lowest Toarcián (Tenuicos-tatum zone) as well as the Middle and Upper Domerian (Margaritatus and Spinatum zones respectively, are probably represented by stratigraphic gaps

Benchmarking for routines and organizational knowledge

We use best practice benchmarking rationales to propose a dynamic research design that accounts for the endogenous components of across-firms heterogeneous routines to study changes in performance and their link to organizational knowledge investments. We thus contribute to the operationalization of management theoretical frameworks based on resources and routines. The research design employs frontier measures that provide industry-level benchmarking in organizational settings, and proposes some new indicators for firm-level strategic benchmarking. A profit-oriented analysis of the U.S. technology industry during 2000-2011 illustrates the usefulness of our design. Findings reveal that industry revival following economic distress comes along with wider gaps between best and worst performers. Second stage analyses show that increasing intangibles stocks is positively associated with fixed target benchmarking, while enhancing R&D spending is linked to local frontier progress. The discussion develops managerial interpretations of the benchmarking measures that are suitable for control mechanisms and reward systems.

Differential regulation of RasGAPs in cancer

Ever since their discovery as cellular counterparts of viral oncogenes more than 25 years ago, much progress has been made in understanding the complex networks of signal transduction pathways activated by oncogenic Ras mutations in human cancers. The activity of Ras is regulated by nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs), and much emphasis has been put into the biochemical and structural analysis of the Ras/GAP complex. The mechanisms by which GAPs catalyze Ras-GTP hydrolysis have been clarified and revealed that oncogenic Ras mutations confer resistance to GAPs and remain constitutively active. However, it is yet unclear how cells coordinate the large and divergent GAP protein family to promote Ras inactivation and ensure a certain biological response. Different domain arrangements in GAPs to create differential protein-protein and protein-lipid interactions are probably key factors determining the inactivation of the 3 Ras isoforms H-, K-, and N-Ras and their effector pathways. In recent years, in vitro as well as cell- and animal-based studies examining GAP activity, localization, interaction partners, and expression profiles have provided further insights into Ras inactivation and revealed characteristics of several GAPs to exert specific and distinct functions. This review aims to summarize knowledge on the cell biology of RasGAP proteins that potentially contributes to differential regulation of spatiotemporal Ras signaling.

Superheavy nuclei in relativistic effective Lagrangian model

Isotopic and isotonic chains of superheavy nuclei are analyzed to search for spherical double shell closures beyond Z=82 and N=126 within the new effective field theory model of Furnstahl, Serot, and Tang for the relativistic nuclear many-body problem. We take into account several indicators to identify the occurrence of possible shell closures, such as two-nucleon separation energies, two-nucleon shell gaps, average pairing gaps, and the shell correction energy. The effective Lagrangian model predicts N=172 and Z=120 and N=258 and Z=120 as spherical doubly magic superheavy nuclei, whereas N=184 and Z=114 show some magic character depending on the parameter set. The magicity of a particular neutron (proton) number in the analyzed mass region is found to depend on the number of protons (neutrons) present in the nucleus.

Inclusion of soil erosion impacts in life cycle assessment on a global scale: application to energy crops in Spain

Purpose: Despite the fundamental role of ecosystem goods and services in sustaining human activities, there is no harmonized and internationally agreed method for including them in life cycle assessment (LCA). The main goal of this study was to develop a globally applicable and spatially resolved method for assessing land-use impacts on the erosion regulation ecosystem service.Methods: Soil erosion depends much on location. Thus, unlike conventional LCA, the endpoint method was regionalized at the grid-cell level (5 arc-minutes, approximately 10×10 km2) to reflect the spatial conditions of the site. Spatially explicit characterization factors were not further aggregated at broader spatial scales. Results and discussion: Life cycle inventory data of topsoil and topsoil organic carbon (SOC) losses were interpreted at the endpoint level in terms of the ultimate damage to soil resources and ecosystem quality. Human health damages were excluded from the assessment. The method was tested on a case study of five three-year agricultural rotations, two of them with energy crops, grown in several locations in Spain. A large variation in soil and SOC losses was recorded in the inventory step, depending on climatic and edaphic conditions. The importance of using a spatially explicit model and characterization factors is shown in the case study.Conclusions and outlook: The regionalized assessment takes into account the differences in soil erosion-related environmental impacts caused by the great variability of soils. Taking this regionalized framework as the starting point, further research should focus on testing the applicability of the method trough the complete life cycle of a product and on determining an appropriate spatial scale at which to aggregate characterization factors, in order to deal with data gaps on location of processes, especially in the background system. Additional research should also focus on improving reliability of the method by quantifying and, insofar as it is possible, reducing uncertainty.
