Aquesta recerca està motivada per l’interès en les Mesures Penals Alternatives, concretament, en les suspensions judicials com a mesura més adient per a determinats subjectes amb perfils toxicològics i que requereixen d’una intervenció que es pot abordar en context comunitari. Per tal de valorar la seva eficà cia, l’equip d’investigadors s’ha centrat en els Ãndexs de reincidència i aquells factors que poden influir a partir de l’anà lisi estadÃstica d’una mostra de 237 subjectes sotmesos a l’obligació de tractament de deshabituació. Observant l’Ãndex de reincidència, en funció de l’anà lisi de variables sociopersonals i judicials dels subjectes, es busquen aquells indicadors que poden ser eficaços per reduir la comissió de nous fets delictius. Del resultats obtinguts, es conclou que variables com una bona adherència familiar, una estabilitat laboral aixà com la finalització correcta d’un tractament de deshabituació aporten uns nivells de reincidència baixos. Igualment, es justifica l’atorgament de suspensions judicials com a eina punitiva més eficaç per a aquells subjectes amb caracterÃstiques toxicològiques i necessitats rehabilitadores a causa de la seva addicció, atès que els nivells de reincidència obtinguts en aquesta recerca aporten uns Ãndexs més baixos que els nivells actuals de reincidència penitencià ria (cal tenir en compte, però, la diferència de perfils). Es conclou que aquestes mesures penals alternatives són una eina més integradora ja que es desenvolupen en l’entorn comunitari.

Esta investigación está motivada por el interés por las suspensiones judiciales como medida más adecuada para determinados sujetos con perfiles toxicológicos y que requieren una intervención que se puede abordar en un contexto comunitario. Con el fin de valorar su eficacia, el equipo de investigadores se ha centrado en los Ãndices de reincidencia y aquellos factores que pueden influir a partir del análisis estadÃstico de una muestra de 237 sujetos sometidos a la obligación de tratamiento de deshabituación. Observando el Ãndice de reincidencia, en función del análisis de variables sociopersonales y judiciales de los sujetos, se buscan aquellos indicadores que pueden ser eficaces para reducir la comisión de nuevos hechos delictivos. De los resultados obtenidos, se concluye que variables como una buena adherencia familiar, la estabilidad laboral o la finalización correcta de un tratamiento de deshabituación aportan unos niveles de reincidencia bajos Asimismo, se justifica el otorgamiento de suspensiones judiciales como herramienta punitiva más eficaz para aquellos sujetos con caracterÃsticas toxicológicas y necesidades rehabilitadoras debido a su adicción, dado que los niveles de reincidencia obtenidos en esta investigación aportan unos Ãndices más bajos que los niveles actuales de reincidencia penitenciaria (siempre teniendo en cuenta la diferencia de perfiles). Se concluye en este estudio que la aplicación de estas medidas penales alternativas son una herramienta más integradora debido a que se desarrolla dentro del entorno comunitario.

Despite the important benefits for firms of commercial initiatives on the Internet, e-commerce is still an emerging distribution channel, even in developed countries. Thus, more needs to be known about the mechanisms affecting its development. A large number of works have studied firms¿ e-commerce adoption from technological, intraorganizational, institutional, or other specific perspectives, but there is a need for adequately tested integrative frameworks. Hence, this work proposes and tests a model of firms¿ business-to-consumer (called B2C) e-commerce adoption that is founded on a holistic vision of the phenomenon. With this integrative approach, the authors analyze the joint influence of environmental, technological, and organizational factors; moreover, they evaluate this effect over time. Using various representative Spanish data sets covering the period 1996-2005, the findings demonstrate the suitability of the holistic framework. Likewise, some lessons are learned from the analysis of the key building blocks. In particular, the current study provides evidence for the debate about the effect of competitive pressure, since the findings show that competitive pressure disincentivizes e-commerce adoption in the long term. The results also show that the development or enrichment of the consumers¿ consumption patterns, the technological readiness of the market forces, the firm¿s global scope, and its competences in innovation continuously favor e-commerce adoption.

Activity decreases, or deactivations, of midline and parietal cortical brain regions are routinely observed in human functional neuroimaging studies that compare periods of task-based cognitive performance with passive states, such as rest. It is now widely held that such task-induced deactivations index a highly organized"default-mode network" (DMN): a large-scale brain system whose discovery has had broad implications in the study of human brain function and behavior. In this work, we show that common task-induced deactivations from rest also occur outside of the DMN as a function of increased task demand. Fifty healthy adult subjects performed two distinct functional magnetic resonance imaging tasks that were designed to reliably map deactivations from a resting baseline. As primary findings, increases in task demand consistently modulated the regional anatomy of DMN deactivation. At high levels of task demand, robust deactivation was observed in non-DMN regions, most notably, the posterior insular cortex. Deactivation of this region was directly implicated in a performance-based analysis of experienced task difficulty. Together, these findings suggest that task-induced deactivations from rest are not limited to the DMN and extend to brain regions typically associated with integrative sensory and interoceptive processes.
Identification-commitment inventory (ICI-Model): confirmatory factor analysis and construct validity
Resumo:
The aim of this study is to confirm the factorial structure of the Identification-Commitment Inventory (ICI) developed within the frame of the Human System Audit (HSA) (Quijano et al. in Revist Psicol Soc Apl 10(2):27-61, 2000; Pap Psicól Revist Col Of Psicó 29:92-106, 2008). Commitment and identification are understood by the HSA at an individual level as part of the quality of human processes and resources in an organization; and therefore as antecedents of important organizational outcomes, such as personnel turnover intentions, organizational citizenship behavior, etc. (Meyer et al. in J Org Behav 27:665-683, 2006). The theoretical integrative model which underlies ICI Quijano et al. (2000) was tested in a sample (N = 625) of workers in a Spanish public hospital. Confirmatory factor analysis through structural equation modeling was performed. Elliptical least square solution was chosen as estimator procedure on account of non-normal distribution of the variables. The results confirm the goodness of fit of an integrative model, which underlies the relation between Commitment and Identification, although each one is operatively different.

Planarians are a group of free-living platyhelminths (triclads) best-known largely due to long-standing regeneration and pattern formation research. However, the group"s diversity and evolutionary history has been mostly overlooked. A few taxonomists have focused on certain groups, resulting in the description of many species and the establishment of higher-level groups within the Tricladida. However, the scarcity of morphological features precludes inference of phylogenetic relationships among these taxa. The incorporation of molecular markers to study their diversity and phylogenetic relationships has facilitated disentangling many conundrums related to planarians and even allowed their use as phylogeographic model organisms. Here, we present some case examples ranging from delimiting species in an integrative style, and barcoding them, to analysing their evolutionary history on a lower scale to infer processes affecting biodiversity origin, or on a higher scale to understand the genus level or even higher relationships. In many cases, these studies have allowed proposing better classifications and resulted in taxonomical changes. We also explain shortcomings resulting in a lack of resolution or power to apply the most up-to-date data analyses. Next-generation sequencing methodologies may help improve this situation and accelerate their use as model organisms.

La aplicación de la resiliencia a la intervención social y educativa la ha convertido en un concepto aglutinador de muchos otros previamente investigados y presentes en la praxis profesional. La resiliencia aporta una mirada integradora que hace de ella una excelente metáfora del bienestar o la calidad de vida que los profesionales sociales contribuyen a desarrollar en los ámbitos en los que intervienen. En este artÃculo revisamos algunas buenas prácticas destacadas por educadores y educadoras sociales para la promoción de los factores protectores y exploramos, mediante la autopercepción de los estudiantes, en qué medida la formación universitaria capacita a los futuros profesionales para desarrollar actuaciones constructoras de resiliencia.

Encara que potser no en siguem conscients, en qualsevol interacció social, des de les més afectuoses fins a les més competitives, sempre ens comparem amb els altres, i comparem els altres amb els està ndards que tenim interioritzats, la qual cosa ens permet identificar-nos com a éssers individuals dins un entorn social i ens ajuda a trobar el lloc que més ens pot afavorir en cada situació concreta. Un treball que s"acaba de publicar a Integrative Systems, realitzat per Gayannée Kedia i els seus col·laboradors, de les universitats de Colònia (Alemanya), Cardiff (Gal·les) i Graz (Àustria), identifica els mecanismes neurals mitjançant els quals aquestes comparacions condicionen el sistema de recompensa del cervell i de retruc la imatge que construïm de nosaltres mateixos. Demostra que són a la base dels sentiments d"enveja i també del plaer que de vegades podem sentir per la dissort dels altres.

Correct species identification is a crucial issue in systematics with key implications for prioritising conservation effort. However, it can be particularly challenging in recently diverged species due to their strong similarity and relatedness. In such cases, species identification requires multiple and integrative approaches. In this study we used multiple criteria, namely plumage colouration, biometric measurements, geometric morphometrics, stable isotopes analysis (SIA) and genetics (mtDNA), to identify the species of 107 bycatch birds from two closely related seabird species, the Balearic (Puffinus mauretanicus) and Yelkouan (P. yelkouan) shearwaters. Biometric measurements, stable isotopes and genetic data produced two stable clusters of bycatch birds matching the two study species, as indicated by reference birds of known origin. Geometric morphometrics was excluded as a species identification criterion since the two clusters were not stable. The combination of plumage colouration, linear biometrics, stable isotope and genetic criteria was crucial to infer the species of 103 of the bycatch specimens. In the present study, particularly SIA emerged as a powerful criterion for species identification, but temporal stability of the isotopic values is critical for this purpose. Indeed, we found some variability in stable isotope values over the years within each species, but species differences explained most of the variance in the isotopic data. Yet this result pinpoints the importance of examining sources of variability in the isotopic data in a case-by-case basis prior to the cross-application of the SIA approach to other species. Our findings illustrate how the integration of several methodological approaches can help to correctly identify individuals from recently diverged species, as each criterion measures different biological phenomena and species divergence is not expressed simultaneously in all biological traits.

Comparative genomics of several strains of Erwinia amylovora, a plant pathogenic bacterium causal agent of fire blight disease, revealed that its diversity is primarily attributable to the flexible genome comprised of plasmids. We recently identified and sequenced in full a novel 65.8 kb plasmid, called pEI70. Annotation revealed a lack of known virulence-related genes, but found evidence for a unique integrative conjugative element related to that of other plant and human pathogens. Comparative analyses using BLASTN showed that pEI70 is almost entirely included in plasmid pEB102 from E. billingiae, an epiphytic Erwinia of pome fruits, with sequence identities superior to 98%. A duplex PCR assay was developed to survey the prevalence of plasmid pEI70 and also that of pEA29, which had previously been described in several E. amylovora strains. Plasmid pEI70 was found widely dispersed across Europe with frequencies of 5–92%, but it was absent in E. amylovora analyzed populations from outside of Europe. Restriction analysis and hybridization demonstrated that this plasmid was identical in at least 13 strains. Curing E. amylovora strains of pEI70 reduced their aggressiveness on pear, and introducing pEI70 into low-aggressiveness strains lacking this plasmid increased symptoms development in this host. Discovery of this novel plasmid offers new insights into the biogeography, evolution and virulence determinants in E. amylovora

Investigaciones recientes sugieren que en la adolescencia tienen lugar importantes cambios en la estructura,bioquÃmica y fisiologÃa del cerebro que podrÃan explicar la dificultad que experimentan los adolescentes en elcontrol de sus emociones asà como también otros rasgos de su comportamiento inestable. En este artÃculo presentamosalgunas investigaciones que establecen, asimismo, una correlación entre las reorganizaciones cerebrales quetienen lugar en el primer año de vida con signos de irritabilidad y desazón emocional que muestra el bebédurante este periodo. En ambos casos la dificultad de controlar los impulsos emocionales es susceptible de afectarla relación de los padres con el niño o joven. Discutimos la posible relevancia de esta coincidencia dentro de unaperspectiva evolucionista asà como la posible vulnerabilidad de estos perÃodos. Finalmente, apuntamos la necesidadde una teorÃa integradora del desarrollo humano y ofrecemos algunos puntos de debate
