El significado de las ocupaciones en las personas mayores-jóvenes: algunas tendencias

Con la llegada del nuevo paradigma del “envejecimiento activo” planteado por la Organización Mundial de la Salud (OMS, 2002), estamos asistiendo a una nueva manera de enfocar el progresivo envejecimiento de la población. Este enfoque trata de fomentar la consecución de una esperanza de vida saludable y libre de discapacidad, gracias a la promoción de políticas y programas cuyos objetivos principales se centran en la independencia y en la autonomía a lo largo del proceso de envejecimiento. Acorde con este enfoque pensamos que las ocupaciones significativas son una buena herramienta para mantener la autonomía de estas personas al fomentar la prevención y la promoción de su salud, motivo por el cual desarrollamos este estudio. Los objetivos principales del presente estudio son conocer y comprender que ocupaciones adquieren un significado y satisfacción personal en las personas mayores-jóvenes, que han concluido su etapa laboral, que cuentan con buena salud y condiciones psicofísicas favorables y que viven de manera autónoma en la comunidad, así como explorar también si se establece en estas personas alguna vinculación entre las actividades que eligen desarrollar en la actualidad con su perfil e historia ocupacional previa. Por último, este estudio pretende conocer el tipo de gestión que cada persona prefiere para llevar a cabo las actividades cotidianas que les son más significativas, a partir de los contextos en los que se inscribe. El marco teórico se desarrolla a partir de la conceptualización aportada por diversos autores sobre el envejecimiento activo y la ciencia de la ocupación. La metodología utilizada es de carácter cualitativo, enfocado desde un paradigma constructivista. Los resultados del estudio muestran que se inicia tímidamente un cambio de tendencias en la elección y el significado que las personas mayores-jóvenes atribuyen a sus ocupaciones. Muestran también que las ocupaciones elegidas como más significativas por estas personas mantienen una vinculación con las que ya realizaban con anterioridad a la jubilación, con su historia o perfil 6 ocupacional previo. Y finalmente demuestran que el tipo de gestión que eligen para efectuarlas influye en la elección del entorno donde las llevan a término.

Destination image of Girona: an online text-mining approach

The main objective of this Master Thesis is to discover more about Girona’s image as a tourism destination from different agents’ perspective and to study its differences on promotion or opinions. In order to meet this objective, three components of Girona’s destination image will be studied: attribute-based component, the holistic component, and the affective component. It is true that a lot of research has been done about tourism destination image, but it is less when we are talking about the destination of Girona. Some studies have already focused on Girona as a tourist destination, but they used a different type of sample and different methodological steps. This study is new among destination studies in the sense that it is based only on textual online data and it follows a methodology based on text-miming. Text-mining is a kind of methodology that allows people extract relevant information from texts. Also, after this information is extracted by this methodology, some statistical multivariate analyses are done with the aim of discovering more about Girona’s tourism image

The underestimation of compliance to direct help requests explained by adaptive sampling

Helping behavior is any intentional behavior that benefits another living being or group (Hogg & Vaughan, 2010). People tend to underestimate the probability that others will comply with their direct requests for help (Flynn & Lake, 2008). This implies that when they need help, they will assess the probability of getting it (De Paulo, 1982, cited in Flynn & Lake, 2008) and then they will tend to estimate one that is actually lower than the real chance, so they may not even consider worth asking for it. Existing explanations for this phenomenon attribute it to a mistaken cost computation by the help seeker, who will emphasize the instrumental cost of “saying yes”, ignoring that the potential helper also needs to take into account the social cost of saying “no”. And the truth is that, especially in face-to-face interactions, the discomfort caused by refusing to help can be very high. In short, help seekers tend to fail to realize that it might be more costly to refuse to comply with a help request rather than accepting. A similar effect has been observed when estimating trustworthiness of people. Fetchenhauer and Dunning (2010) showed that people also tend to underestimate it. This bias is reduced when, instead of asymmetric feedback (getting feedback only when deciding to trust the other person), symmetric feedback (always given) was provided. This cause could as well be applicable to help seeking as people only receive feedback when they actually make their request but not otherwise. Fazio, Shook, and Eiser (2004) studied something that could be reinforcing these outcomes: Learning asymmetries. By means of a computer game called BeanFest, they showed that people learn better about negatively valenced objects (beans in this case) than about positively valenced ones. This learning asymmetry esteemed from “information gain being contingent on approach behavior” (p. 293), which could be identified with what Fetchenhauer and Dunning mention as ‘asymmetric feedback’, and hence also with help requests. Fazio et al. also found a generalization asymmetry in favor of negative attitudes versus positive ones. They attributed it to a negativity bias that “weights resemblance to a known negative more heavily than resemblance to a positive” (p. 300). Applied to help seeking scenarios, this would mean that when facing an unknown situation, people would tend to generalize and infer that is more likely that they get a negative rather than a positive outcome from it, so, along with what it was said before, people will be more inclined to think that they will get a “no” when requesting help. Denrell and Le Mens (2011) present a different perspective when trying to explain judgment biases in general. They deviate from the classical inappropriate information processing (depicted among other by Fiske & Taylor, 2007, and Tversky & Kahneman, 1974) and explain this in terms of ‘adaptive sampling’. Adaptive sampling is a sampling mechanism in which the selection of sample items is conditioned by the values of the variable of interest previously observed (Thompson, 2011). Sampling adaptively allows individuals to safeguard themselves from experiences they went through once and turned out to lay negative outcomes. However, it also prevents them from giving a second chance to those experiences to get an updated outcome that could maybe turn into a positive one, a more positive one, or just one that regresses to the mean, whatever direction that implies. That, as Denrell and Le Mens (2011) explained, makes sense: If you go to a restaurant, and you did not like the food, you do not choose that restaurant again. This is what we think could be happening when asking for help: When we get a “no”, we stop asking. And here, we want to provide a complementary explanation for the underestimation of the probability that others comply with our direct help requests based on adaptive sampling. First, we will develop and explain a model that represents the theory. Later on, we will test it empirically by means of experiments, and will elaborate on the analysis of its results.

Modeling and control of electromechanical systems

The material presented in the these notes covers the sessions Modelling of electromechanical systems, Passive control theory I and Passive control theory II of the II EURON/GEOPLEX Summer School on Modelling and Control of Complex Dynamical Systems.We start with a general description of what an electromechanical system is from a network modelling point of view. Next, a general formulation in terms of PHDS is introduced, and some of the previous electromechanical systems are rewritten in this formalism. Power converters, which are variable structure systems (VSS), can also be given a PHDS form.We conclude the modelling part of these lectures with a rather complex example, showing the interconnection of subsystems from several domains, namely an arrangement to temporally store the surplus energy in a section of a metropolitan transportation system based on dc motor vehicles, using either arrays of supercapacitors or an electric poweredflywheel. The second part of the lectures addresses control of PHD systems. We first present the idea of control as power connection of a plant and a controller. Next we discuss how to circumvent this obstacle and present the basic ideas of Interconnection and Damping Assignment (IDA) passivity-based control of PHD systems.

Group motivational intervention in overweight/obese patients in primary prevention of cardiovascular disease in the primary healthcare area

Background The global mortality caused by cardiovascular disease increases with weight. The Framingham study showed that obesity is a cardiovascular risk factor independent of other risks such as type 2 diabetes mellitus, dyslipidemia and smoking. Moreover, the main problem in the management of weight-loss is its maintenance, if it is achieved. We have designed a study to determine whether a group motivational intervention, together with current clinical practice, is more efficient than the latter alone in the treatment of overweight and obesity, for initial weight loss and essentially to achieve maintenance of the weight achieved; and, secondly, to know if this intervention is more effective for reducing cardiovascular risk factors associated with overweight and obesity. Methods This 26-month follow up multi-centre trial, will include 1200 overweight/obese patients. Random assignment of the intervention by Basic Health Areas (BHA): two geographically separate groups have been created, one of which receives group motivational intervention (group intervention), delivered by a nurse trained by an expert phsychologist, in 32 group sessions, 1 to 12 fortnightly, and 13 to 32, monthly, on top of their standard program of diet, exercise, and the other (control group), receiving the usual follow up, with regular visits every 3 months. Discussion By addressing currently unanswered questions regarding the maintenance in weight loss in obesity/overweight, upon the expected completion of participant follow-up in 2012, the IMOAP trial should document, for the first time, the benefits of a motivational intervention as a treatment tool of weight loss in a primary care setting.

Experiencias de interoperabilidad entre CRIS y repositorios en Catalunya

Toni Prieto, Técnico IC del Servicio de Bibliotecas y Documentación (SBD) de la UPC, en su presentación 'Experiencias de interoperabilidad entre CRIS y repositorios en Catalunya', describió la integración del repositorio UPCommons y del CRIS DRAC (Descriptor de la Recerca i l'Activitat Acadèmica) de la UPC. El resultado de esta integración es un esquema integrado de archivo CRIS/IR en dos fases, envío y revisión, en el que los metadatos se introducen en DRAC -para posteriormente ser transferidos, validados y enriquecidos si procede- y el archivo de texto completo asociado se realiza en UPCommons. De manera similar funciona la integración de GIR (Gestió Integral de la Recerca, basado en Universitas XXI Investigación) y el repositorio O2 en la UOC, permitiendo la asignación del identificador handle de un ítem en O2 a una referencia en GIR. Ambos sistemas, DRAC en la UPC y GIR en la UOC, están integrados en el Proyecto CVN de generación de CVs normalizados. Se mencionaron asimismo experiencias posteriores de integración CRIS/IR actualmente en curso en la Universitat de Barcelona y en la U Pompeu Fabra, y se mostró el impacto significativo de la estrategia de integración de sistemas sobre el ritmo de incorporación de contenidos a UPCommons.

eggNOG v4.0: nested orthology inference across 3686 organisms

With the increasing availability of various 'omics data, high-quality orthology assignment is crucial for evolutionary and functional genomics studies. We here present the fourth version of the eggNOG database (available at http://eggnog.embl.de) that derives nonsupervised orthologous groups (NOGs) from complete genomes, and then applies a comprehensive characterization and analysis pipeline to the resulting gene families. Compared with the previous version, we have more than tripled the underlying species set to cover 3686 organisms, keeping track with genome project completions while prioritizing the inclusion of high-quality genomes to minimize error propagation from incomplete proteome sets. Major technological advances include (i) a robust and scalable procedure for the identification and inclusion of high-quality genomes, (ii) provision of orthologous groups for 107 different taxonomic levels compared with 41 in eggNOGv3, (iii) identification and annotation of particularly closely related orthologous groups, facilitating analysis of related gene families, (iv) improvements of the clustering and functional annotation approach, (v) adoption of a revised tree building procedure based on the multiple alignments generated during the process and (vi) implementation of quality control procedures throughout the entire pipeline. As in previous versions, eggNOGv4 provides multiple sequence alignments and maximum-likelihood trees, as well as broad functional annotation. Users can access the complete database of orthologous groups via a web interface, as well as through bulk download.

Sink limitations to yield in wheat : how could it be reduced?

Further genetic gains in wheat yield are required to match expected increases in demand. This may require the identification of physiological attributes able to produce such improvement, as well as the genetic bases controlling those traits in order to facilitate their manipulation. In the present paper, a theoretical framework of source and sink limitation to wheat yield is presented and the fine-tuning of crop development as an alternative for increasing yield potential is discussed. Following a top-down approach, most crop physiologists have agreed that the main attribute explaining past genetic gains in yield was harvest index (HI). By virtue of previous success, no further gains may be expected in HI and an alternative must be found. Using a bottom-up approach, the present paper firstly provides evidence on the generalized sink-limited condition of grain growth, determining that for further increases in yield potential, sink strength during grain filling has to be increased. The focus should be on further increasing grain number per m2, through fine-tuning pre-anthesis developmental patterns. The phase of rapid spike growth period (RSGP) is critical for grain number determination and increasing spike growth during pre-anthesis would result in an increased number of grains. This might be achieved by lengthening the duration of the phase (though without altering flowering time), as there is genotypic variation in the proportion of pre-anthesis time elapsed either before or after the onset of the stem elongation phase. Photoperiod sensitivity during RSGP could be then used as a genetic tool to further increase grain number, since slower development results in smoother floret development and more floret primordia achieve the fertile floret stage, able to produce a grain. Far less progress has been achieved on the genetic control of this attribute. None of the well-known major Ppd alleles seems to be consistently responsible for RSGP sensitivity. Alternatives for identifying the genetic factors responsible for this sensitivity (e.g. quantitative trait locus (QTL) identification in mapping populations) are being considered.

Relació entre la lateralitat i els aprenentatges escolars

Hi ha molts autors que relacionen els problemes d’aprenentatge d’un nen amb la seva lateralitat, i que atribueixen a la lateralitat contrariada, creuada o no definida els problemes en l’adquisició, entre altres, d’habilitats lectoescriptores. En aquest treball hem passat un test de lateralitat a 170 nens d’entre 6 i 7 anys (primer i segon de primària) amb proves de membre superior, membre inferior i ull, igual com de discriminació de dreta-esquerra i d’orientació espacial. Alhora, els professors tutors han valorat diversos ítems de l’aprenentatge escolar dels nens, amb qüestions sobre la seva comprensió lectora, el seu raonament matemàtic i la seva atenció a classe, entre d’altres. Segons els nostres resultats, els nens amb lateralitat homogènia destra són els que obtenen millors valoracions a tots els ítems d’aprenentatge respecte als homogenis esquerrans, els creuats i els no confirmats; els pocs casos que tenim d’homogenis esquerrans (un 3 % de la mostra) són els que tenen pitjors valoracions. A més a més, els nens que discriminen entre dreta i esquerra també tenen millors aprenentatges que no pas els que no ho fan; també s’orienten bé en l’espai en relació als que s’orienten malament.

Relación entre la lateralidad y los aprendizajes escolares

Muchos son los autores que relacionan los problemas de aprendizaje de un niño con su lateralidad, achacando a la lateralidad contrariada, cruzada o no definida los problemas en la adquisición, entre otras, de habilidades lecto-escritoras. En el presente trabajo hemos pasado un test de lateralidad a 170 niños de entre 6 y 7 años (primero y segundo de primaria) con pruebas de miembro superior, miembro inferior y ojo, así como de discriminación de derecha-izquierda y de orientación espacial. A su vez, los profesores tutores han valorado varios ítems del aprendizaje escolar de los niños, con cuestiones sobre su comprensión lectora, su razonamiento matemático y su atención en clase, entre otras. Según nuestros resultados, los niños con lateralidad homogénea diestra son los que obtienen mejores valoraciones en todos los ítems de aprendizaje con respecto a los homogéneos zurdos, los cruzados y los no confirmados, siendo los pocos casos que tenemos de homogéneos zurdos (un 3% de la muestra) los que tienen peores valoraciones. Además, los niños que discriminan entre derecha e izquierda también tienen mejor sus aprendizajes con respecto a los que no lo hacen, así como los que se orientan bien en el espacio con respecto a los que se orientan mal.

The Impact of a Character Posture Model on the Communication of Affect in an Immersive Virtual Environment

This paper presents the quantitative and qualitative findings from an experiment designed to evaluate a developing model of affective postures for full-body virtual characters in immersive virtual environments (IVEs). Forty-nine participants were each requested to explore a virtual environment by asking two virtual characters for instructions. The participants used a CAVE-like system to explore the environment. Participant responses and their impression of the virtual characters were evaluated through a wide variety of both quantitative and qualitative methods. Combining a controlled experimental approach with various data-collection methods provided a number of advantages such as providing a reason to the quantitative results. The quantitative results indicate that posture plays an important role in the communication of affect by virtual characters. The qualitative findings indicated that participants attribute a variety of psychological states to the behavioral cues displayed by virtual characters. In addition, participants tended to interpret the social context portrayed by the virtual characters in a holistic manner. This suggests that one aspect of the virtual scene colors the perception of the whole social context portrayed by the virtual characters. We conclude by discussing the importance of designing holistically congruent virtual characters especially in immersive settings.

Data-division-specific robustness and power of randomization tests for ABAB designs

This study deals with the statistical properties of a randomization test applied to an ABAB design in cases where the desirable random assignment of the points of change in phase is not possible. In order to obtain information about each possible data division we carried out a conditional Monte Carlo simulation with 100,000 samples for each systematically chosen triplet. Robustness and power are studied under several experimental conditions: different autocorrelation levels and different effect sizes, as well as different phase lengths determined by the points of change. Type I error rates were distorted by the presence of autocorrelation for the majority of data divisions. Satisfactory Type II error rates were obtained only for large treatment effects. The relationship between the lengths of the four phases appeared to be an important factor for the robustness and the power of the randomization test.

Addenda a la biografia i l'obra del pintor Joan Arnau Moret (1603-1693)

The present article treats of the painter Joan Arnau Moret, catalan painter of the 17th century. Aspects treat each other as the order of the great picture preserved in the cathedral of Barcelona with the iconography The de live ry o f the ke ys of the city of Barcelona to the Immaculate, the biographical news it extracted of the process of canonization of santa Maria of Cervelló or the professional relation that Joan Arnau joined with the prince Joan Josep d’Àustria newly finished the Segadors war (The Reapers’ War). Of them the study also announces a work – the Saint Cathe rine o f Ale xandria of the chapel of Saint Catherine of the cathedral of Girona – proposes to attribute four paintings more – the paintings of the altarpiece of The Saints fo ur Martyrs of the cathedral of Girona – and thinks about the controversial paintings of the altarpiece of the Castle of Vilassar and of the monastery of Sant Joan of the Abadesses. Finally, by means of the stylistic reading of the new works, which the author considers of the best of his catalogue, one tries to demonstrate that thesources of your figurative culture and stylistic are in the painting of Madrid of the first decades of the 17th century
