Desenvolupament de mesures per comparar transculturalment xarxes personals (USA i Estats Units)

Estudi elaborat a partir d’una estada a la Universitat de Florida durant Abril i Maig de 2006. “Application to Immigrant Populations in South Florida and Northeastern Spain" ha permès recollir les xarxes personals d’immigrants en els dos països mitjançant un qüestionari implementat amb un software desenvolupat ex professo per recollir i presentar visualment les dades. Es van revisar i assemblar les entrevistes i qüestionaris realitzats a Catalunya i a Estats Units (Miami i Nova York, especialment). Fins al moment s’han revisat i analitzat uns 450 casos. Un cop depurada i analitzada la informació obtinguda s’ha pogut disposar per primer cop de mesures globals pels diferents col•lectius estudiats. L'objectiu global del projecte és entendre les implicacions que les estructures de les xarxes personals tenen en relació a un conjunt de conductes (de salut, d'ús de la llengua, etx) i les autoconcepcions. En aquest sentit era necessari desenvolupar un seguit de mesures que permetessin comparar i documentar la variació de les estructures de les xarxes personals a diferents cultures, nivells socioeconòmics, gènere, religió, etc. i incorporar-les com a variables independents als models explicatius.En aquest moments s’està desenvolupant un índex basat en variables estructurals (número de components de la xarxa, densitat, grau d’intermediació, etc.) i variables de composició (proporció de persones diferents del país d’origen, entre d'altres). La idea és disposar d’un índex d’heterogeneïtat de la xarxa social comparable entre els diferents col•lectius. Malgrat que el treball continua, la principal conclusió a la que s’ha arribat és que al menys a Espanya a mida que passa el temps augmenta el nivell d’heterogeneïtat de les xarxes personals. És a dir, que desprès d’un ràpid procés de canvi i una fase de transnacionalitat la tendència és a reduir aquest nivell (pels costos socials i econòmics que comporta) depenent, naturalment, de factors com l’origen temporal (primera onada o successives), el tipus de col•lectiu i el sexe.

Noves tecnologies per l'estudi de l'arqueologia de Patagònia (Amèrica del Sud)

The goal of this project was the historical study of Patagonia, the southernmost human settled area of the world. Our aim has been the anlysis of those societies to understand how they maintained their socioeconomic system, that is to say, how social reproduction allowed resolving the basic contradiction between production and reproduction, which is characteristic of all hunter-gatherer societies. New computational technologies have allowed a bettwer integration of the big amount and diversity of data needed. We have analyzed the historical evolution of inter-group and intra-group social relationships among nomad patagonian societies. We have compared different social answers in front of the radical change of their immediate reality produced by european colonization. We have exhaustively analyzed the results of archaeological excavations from diferent regions. We have also integrated information from anthropology, ethnohistory and geography. We are developing computing programs to integrate geographical actual data with paleoenvironmental data about the dynamic nature of soil formation, vegetation, hidrography, etc., with information about the history of productive action and how products were distributed among different human groups.

Asymmetries in the opportunity structure. Intergenerational mobility trends in Europe

It remains unclear whether social mobility is increasing in the advancednations. The answer may depend on mobility patterns within very recentbirth cohorts. We use the inter-generational module in the 2005 EUSILCwhich allows us to include more recent cohorts. Comparingacross two Nordic and three Continental European countries, weestimate inter-generational mobility trends for sons both indirectly, viasocial origin effects on educational attainment, and directly in terms ofadult income attainment. In line with other studies we find substantiallymore mobility in Scandinavia, but also that traditionally less mobilesocieties, like Spain, are moving towards greater equality. We focusparticularly on non-linear relations. Most interestingly, we revealevident asymmetries in the process of equalizing life chances, inDenmark. The disadvantages associated with low social class originshave largely disappeared, but the advantages related to privilegedorigins persist.

Predictors of political orientation among US-born Mexican Americans: cultural identification, acculturation attitudes and socioeconomic status

With each passing election, U.S. political campaigns have renewed their efforts in courting the “Latino vote,” yet the Latino population is not a culturally homogenous voting bloc. This study examined how cultural identifications and acculturation attitudes in U.S. born Mexican Americans interacted with socioeconomic status (SES) to predict political orientation. Individuals who held stronger Mexican identity and supported biculturalism as an acculturation strategy had a more liberal orientation, while belonging to a higher SES group and holding stronger assimilation attitudes predicted a less liberal orientation. Mexican cultural identification interacted with SES such that those who held a weaker Mexican identity, but came from a higher social class were less liberal and more moderate in their political orientation. Weak Mexican identification and higher SES also predicted weaker endorsement of bicultural acculturation attitudes, which in turn, mediated the differences in political orientation. The acceptance of one’s ethnic identity and endorsement of bicultural attitudes predicted a more liberal political orientation. In light of these findings, political candidates should be cautious in how they pander to Latino constituents—referencing the groups’ ethnic culture or customs may distance constituents who are not strongly identified with their ethnic culture.

Married to intolerance: Attitudes towards intermarriage in Germany, 1900-2006

Marriage is amongst the biggest decisions in life. In general, there is a tendency towards assortative matching people marry others who are relatively similar to themselves. Intermarriage between different social, religious and ethnic groups in most societies is relatively rare (Blossfeld and Timm 2003). Where it occurs, it is associated with more rapid assimilation (Meng and Gregory 2005). The frequency of intermarriage can therefore serve as a useful indicator of tolerant attitudes towards a minority, and of the desire to integrate (Bisin, Topa, and Verdier 2004).In this paper, we analyze under which conditions intermarriage can be used as an indicator of tolerance, and whether such tolerant attitudes persisted in Germany during the last century. We combine information on individual-level attitudes from the German social survey (GESIS) with historical data on marriage patterns.

Low birthweight, preterm, and small for gestational age babies in Scotland, 1981-1984.

The aim was to examine the effect of maternal age, gravidity, marital status, previous perinatal deaths, and parental social class on babies born low birthweight, preterm, and small for gestational age. DESIGN--The study used data on discharge summaries from all maternity hospitals in Scotland. SETTING--The study was based on all singleton deliveries in Scotland. PARTICIPANTS--The analysis involved information on 259,462 singleton babies born during the four years 1981-84 in Scotland. MEASUREMENTS AND MAIN RESULTS--Previous perinatal death was found to be the strongest predictor for both preterm and low birthweight. Single mothers were at particularly high risk of having a small for gestational age baby and those who were previously married of having a preterm baby. Women aged less than 20 years old, those over 34 years old, nulligravidae, and those of parity 3 or more were also at increased risk of adverse pregnancy outcome. Mothers and fathers in manual social classes and those who could not be assigned a social class on the basis of their occupation were at increased risk for all three adverse outcomes studied. The babies of parents who were in manual occupations were twice as likely as those of parents in non-manual occupations to be small for gestational age and almost twice as likely to be low birthweight. CONCLUSIONS--Mother's social class is a risk factor for adverse pregnancy outcome independent of maternal age, parity, and adverse reproductive history, and also independent of father's social class. Information on both parents' occupations should be collected in maternity discharge systems.

Multimodal Strategies in Development.Predictive Value of early simultaneosgesture-speech comination

The present study investigates the predictive value of the early appearance of simultaneous pointing-speech combinations. An experimental task was used to obtain a communicative productive sample from nineteen children at 1;0 and 1;3. Infant’s communicative productions, in combination with gaze joint engagement patterns, were analyzed in relation to different social conditions. The results show a significant effect of age and social condition on infants’ communicative productions. Gesture-speech combinations seem to work as a strong communicative resource to attract the adult’s attention in social demanding communicative contexts. Gaze joint engagement was used in combination with simultaneous pointing-speech combinations to attract adults’ attention during social demanding conditions. Finally, the use of simultaneous pointing-speech combinations at 1;0 in demanding conditions predicted greater expressive vocabulary acquisition at 1;3 and 1;6. These results indicate that the use of gesture-speech combinations may be considered a significant step towards the early integration of language components.

Transcriptome analyses of primitively eusocial wasps reveal novel insights into the evolution of sociality and the origin of alternative phenotypes

BACKGROUND: Understanding how alternative phenotypes arise from the same genome is a major challenge in modern biology. Eusociality in insects requires the evolution of two alternative phenotypes - workers, who sacrifice personal reproduction, and queens, who realize that reproduction. Extensive work on honeybees and ants has revealed the molecular basis of derived queen and worker phenotypes in highly eusocial lineages, but we lack equivalent deep-level analyses of wasps and of primitively eusocial species, the latter of which can reveal how phenotypic decoupling first occurs in the early stages of eusocial evolution. RESULTS: We sequenced 20 Gbp of transcriptomes derived from brains of different behavioral castes of the primitively eusocial tropical paper wasp Polistes canadensis. Surprisingly, 75% of the 2,442 genes differentially expressed between phenotypes were novel, having no significant homology with described sequences. Moreover, 90% of these novel genes were significantly upregulated in workers relative to queens. Differential expression of novel genes in the early stages of sociality may be important in facilitating the evolution of worker behavioral complexity in eusocial evolution. We also found surprisingly low correlation in the identity and direction of expression of differentially expressed genes across similar phenotypes in different social lineages, supporting the idea that social evolution in different lineages requires substantial de novo rewiring of molecular pathways. CONCLUSIONS: These genomic resources for aculeate wasps and first transcriptome-wide insights into the origin of castes bring us closer to a more general understanding of eusocial evolution and how phenotypic diversity arises from the same genome.

Cultures familiars, mitjans digitals i joves. Restriccions explícites i implícites en la reproducció de l'avantatge generalitzat

La irrupció dels mitjans digitals està generant en les famílies amb adolescents noves formes d'estar junts i de relacionar-se amb l'exterior, que són viscuts sovint amb ansietat per part dels pares. Per estudiar les normes que tant els pares com els seus fills estan generant per regular-les, i com aquestes regulacions es relacionen amb la reproducció de l'avantatge i el desavantatge generalitzat, es proposa superar l'orientació restringida dels riscos i oportunitats i fixar-se en canvi en la manera comles cultures i identitats familiars generen equilibris particulars en les tensions normatives del treball, el consum i l'autenticitat. Mitjançant una recerca empírica qualitativa amb 23 famílies de dos centres d'educació secundària de l'àrea metropolitana de Barcelona, es constata que enlloc de buscar com normes o estils parentals concrets es relacionen amb diferents posicions socials, és preferible analitzar com les diferents cultures i identitats familiars regulen l'adquisició d'autonomia per part dels fills. Aspectes com la familiaritat i reflexivitat vers la tecnologia, l'establiment de rutines i horaris familiars o els contextos relacionals esdevenen així claus per entendre la reproducció de l'avantatge generalitzat. Aquests elements permeten contextualitzar dinàmicament la complexa combinació de les regulacions implícites i explícites en el procés de maduració dels fills.

La réciprocité comme stratégie pour gérer la faim et la précarité alimentaire

Le texte littéraire, examiné et contextualisé historiquement, offre des voies de compréhension des stratégies mises en oeuvre par une classe sociale afin de se perpétuer en période de crise. Ainsi, en considérant spécifiquement certaines des figures de la réciprocité, nous observons l’importance, non seulement des liens sociaux qui favorisent la reproduction sociale, mais aussi celle de l’alimentation comme moteur d’établissement de ces liens.

In memoriam Antonio Prevosti (1919-2011), a pioneer of genetics of natural populations

Prof. Dr. Antonio Prevosti was born on the 15th of February, 1919, at Barcelona where he grew up and lived with his wife Maria Monclús and his family until his death. Between the years 1939 and 1942 he registered at the University of Barcelona and finished his studies there with the"University Degree in Natural Science" obtaining the extraordinary award of his promotion. Immediately afterwards he started his research about the growth rate of Barcelona school children from two very different social groups at the Anthropology Laboratory of the University of Barcelona. The obtained results were published in his Doctoral Thesis (1948). Further investigations on quantitative traits in human populations improved his knowledge of statistical analyses and provided the basis for a scholarship from the Italian Ministry of Foreign Affairs to work at the Institute of Statistical and Demographical Sciences in Rome directed by Prof. C. Gini.

Del Estado-nación al Estado-marca. El rol de la diplomacia pública y la marca de país en el nuevo escenario de las relaciones internacionales

El establecimiento de relaciones entre países en un entorno global parece requerir nuevas estrategias que trascienden la tradicional diplomacia de Estado. La diplomacia pública deviene una renovada estrategia de proyección internacional, donde la marca de país ejerce un importante papel a modo de dispositivo aglutinador y de transmisión de identidades nacionales. De este modo, el nuevo “poder blando” de la representación geográfica parece transcurrir en el seno del debilitamiento del Estado-nación y en claro beneficio de una nueva forma de comunicar la identidad de un país más próxima a la intervención de diferentes agentes sociales que a la firma de tratados internacionales de competencia gubernamental. A partir de una revisión de la literatura existente, este artículo presenta un estado del arte relacionado con las nuevas estrategias de representatividad internacional llevadas a cabo por países y naciones.

La construcción de la marca ‘Qatar’ a partir del deporte: ‘sports place branding’ y prensa deportiva catalana

Los grandes eventos deportivos se han utilizado con fines promocionales para los territorios desde el siglo XIX. En este sentido, la Copa del Mundo de la FIFA de 2022, que se celebrará en Qatar, deviene una excusa ideal para el gobierno de la nación para legitimar su posicionamiento internacional, así como para participar activamente en el negocio mundial del fútbol. Además, desde 2011, Qatar Foundation (QF) ejecuta un acuerdo de patrocinio con el FC Barcelona, último campeón de la UEFA Champions League (ECL) y del Mundial de Clubes de la FIFA (2011), que le permitirá desarrollar proyectos sociales vinculados a la marca Barça en todo el mundo. Este artículo tiene el objetivo de analizar el posicionamiento internacional de Qatar, canalizado mediante un proceso de construcción de marca protagonizado por el deporte y proyectado a través de los medios de comunicación qataríes (AlJazzera) y los propios de los territorios donde el gobierno qatarí invierte, como es el caso de Cataluña.

Entrevista y urgencia social: un reto para las competencias profesionales del educador social

Si decimos que los seres humanos sólo son capaces de vivir como tales mediante la reconstrucción narrativa de sus experiencias, estamos teniendo en cuenta conceptos e ideas que recuerdan a algunos autores contemporáneos (Ricoeur, Gadamer) que defienden la importancia de ser reconocido como una creatura hecha de palabras. En la medida en que son interpretadas, traducidas, contextualizadas y ordenadas por los profesionales, la situación dialogal significativa cobra importancia. Desde esta perspectiva hemos planteado las asignaturas: Habilidades Sociales, Técnicas de Entrevista y Gestión de Situación de Crisis diseñadas para integrar los diferentes modelos teóricos y las variables que se presentan en la relación comunicativa con el usuario y en particular en la situación de entrevista. Se mostrará también el modo cómo en nuestro proceso formativo, basado en la simulación de situaciones, se fomenta el compromiso con el trabajo en equipo, la autocomprensión y enseña a crear un clima de trabajo cooperativo en el que se hace más eficaz la relación de ayuda. A través de la presentación en clase de un caso práctico en el cual se describen todos los procedimientos y las fases del que se compone el ejercicio de la práctica profesional –paso a paso-, se busca poner de manifiesto las competencias adquiridas, los modelos empleados y las habilidades sociales que han sido necesarias para afrontar con éxito la situación de urgencia social. Finalmente se deja abierta la cuestión sobre la manera en que incide y beneficia este aprendizaje en las futuras situaciones de manejo del estrés profesional (burn out).

Decomposing Cross-Country Gaps in Obesity and Overweight: Does the Social Environment Matter?

[cat] Una qüestió clau sobre la producció de salut relativament poc explorada es refereix a la influència dels factors socioeconòmics i mediambientals sobre el pes i l’obesitat. Aquesta problemàtica adquireix particular rellevància quan es comparen dos països Mediterranis com Itàlia i Espanya. És interessant adonar-se que l’obesitat a Espanya és 5 punts percentual més elevada al 2003 mentre que a l’any 1990 era aproximadament la mateixa en ambdós països. Aquesta article presenta una descomposició no lineal dels gaps o diferencials en taxes de sobrepès (índex de massa corporal – IMC- entre 25 i 29.9 9 kg/m2), obesitat classe 1 (IMC≥30 kg/m2) i classe 2 (IMC≥35 kg/m2) entre Espanya i Itàlia per gènere i grups d’edat. En explicar aquests gaps entre països aïllem les influències dels estils de vida, els efectes socioeconòmics i els mediambientals. Els nostres resultats indiquen que quan no es controla pels efectes mediambientals (efectes de grup o ‘peer effects’) els hàbits alimentaris i el nivell educatiu són els principals predictors del gaps totals entre països (36-52%), si bé aquests dos factors exerceixen un impacte diferenciat segons gènere i edat. Un tant paradoxalment, quan controlem pels efectes de grup aquests predictors perden la seva capacitat explicativa i els efectes de grup passen a explicar entre el 46-76% dels gaps en sobrepès i obesitat i mostren un patró creixent amb l’edat.
