Over the past decade, mindfulness practices have been used with increasing frequency as therapeutic components within cognitive behavioral treatment regimens. As is standard practice, prescriptive uses of mindfulness intervention are incorporated to improve end-state functioning by ameliorating problematic symptoms and conditions. Common change-targets include the control of cognitive and emotional content for purposes of enhancing psychological self-regulation and physical well-being. The term mindfulness applies to a heterogeneous range of practices, methods, and techniques. While there is no singular agreed upon definition for mindfulness, as a process concept, the term connotes an immediate, non-thetic access to events, wherein each occasioning event is experienced in toto within the broader contextual event-field, and distinct from intervening conceptual themes being noticed. Training in mindfulness practices may be conducted using individual, group, or small class formats. The current paper provides a meta-analytic review of 44 treatment outcome studies (extracted 1982 through 2006), which examines the clinical utility of mindfulness as the primary therapeutic approach. Results indicated that average effect sizes for mindfulness based interventions fell within the medium range for construct category variables examined (d = .56). These findings suggest that mindfulness training is a cost-effective treatment for a wide array of contemporary psychological problems and diagnoses, in addition to fostering positive psychology attributes such as quality and satisfaction with life. A critique of the research and recommendations for future research, including a need to examine the role of mindfulness as a tool for cultivating increased psychological acceptance and life satisfaction, is presented.

The appearance of ferromagnetic correlations among π electrons of phenanthrene (C14H10) molecules in the herringbone structure is proven for K doped clusters both by ab initio quantum-chemistry calculations and by the direct solution of the many-body Pariser-Parr-Pople Hamiltonian. Magnetic ground states are predicted for one or three additional electrons per phenanthrene molecule. These results are a consequence of the small overlap between the lowest unoccupied molecular orbitals (and lowest unoccupied molecular orbitals + 1) of neutral neighboring phenanthrene molecules, which makes the gain in energy by delocalization similar to the corresponding increase due to the Coulomb interaction.

Context. The open cluster NGC 7419 is known to contain five red supergiants and a very high number of Be stars. However, there are conflicting reports about its age and distance that prevent a useful comparison with other clusters. Aims. We intend to obtain more accurate parameters for NGC 7419, using techniques different from those of previous authors, so that it may be used as a calibrator for more obscured clusters. Methods. We obtained Strömgren photometry of the open cluster NGC 7419, as well as classification spectroscopy of ~20 stars in the area. We then applied standard analysis and classification techniques. Results. We find a distance of 4 ± 0.4 kpc and an age of 14 ± 2 Myr for NGC 7419. The main-sequence turn-off is found at spectral type B1, in excellent agreement. We identify 179 B-type members, implying that there are more than 1200 M⊙ in B stars at present. Extrapolating this to lower masses indicates an initial cluster mass of between 7000 and 10 000 M⊙, depending on the shape of the initial mass function. We find a very high fraction (≈40%) of Be stars around the turn-off, but very few Be stars at lower masses. We also report for the first time a strong variability in the emission characteristics of Be stars. We verified that the parameters of the red supergiant members can be used to obtain accurate cluster parameters. Conclusions. NGC 7419 is sufficiently massive to serve as a testbed for theoretical predictions and as a template to compare more obscured clusters. The distribution of stars above the main-sequence turn-off is difficult to accommodate with current evolutionary tracks. Though the presence of five red supergiants is marginally consistent with theoretical expectations, the high number of Be stars and very low number of luminous evolved B stars hint at some unknown physical factor that is not considered in current synthesis models.

Context. Young massive clusters are key to map the Milky Way’s structure, and near-infrared large area sky surveys have contributed strongly to the discovery of new obscured massive stellar clusters. Aims. We present the third article in a series of papers focused on young and massive clusters discovered in the VVV survey. This article is dedicated to the physical characterization of VVV CL086, using part of its OB-stellar population. Methods. We physically characterized the cluster using JHKS near-infrared photometry from ESO public survey VVV images, using the VVV-SkZ pipeline, and near-infrared K-band spectroscopy, following the methodology presented in the first article of the series. Results. Individual distances for two observed stars indicate that the cluster is located at the far edge of the Galactic bar. These stars, which are probable cluster members from the statistically field-star decontaminated CMD, have spectral types between O9 and B0 V. According to our analysis, this young cluster (1.0 Myr < age < 5.0 Myr) is located at a distance of 11+5-6 kpc, and we estimate a lower limit for the cluster total mass of (2.8+1.6-1.4) · 103 M⊙. It is likely that the cluster contains even earlier and more massive stars.

Context. VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Milky Way bulge and an adjacent section of the disk, and one of the principal objectives is to search for new star clusters within previously unreachable obscured parts of the Galaxy. Aims. The primary motivation behind this work is to discover and analyze obscured star clusters in the direction of the inner Galactic disk and bulge. Methods. Regions of the inner disk and bulge covered by the VVV survey were visually inspected using composite JHKS color images to select new cluster candidates on the basis of apparent overdensities. DR1, DR2, CASU, and point spread function photometry of 10 × 10 arcmin fields centered on each candidate cluster were used to construct color–magnitude and color–color diagrams. Follow-up spectroscopy of the brightest members of several cluster candidates was obtained in order to clarify their nature. Results. We report the discovery of 58 new infrared cluster candidates. Fundamental parameters such as age, distance, and metallicity were determined for 20 of the most populous clusters.

Two new hybrid molybdenum(IV) Mo3S7 cluster complexes derivatized with diimino ligands have been prepared by replacement of the two bromine atoms of [Mo3S7Br6]2− by a substituted bipyridine ligand to afford heteroleptic molybdenum(IV) Mo3S7Br4(diimino) complexes. Adsorption of the Mo3S7 cores from sample solutions on TiO2 was only achieved from the diimino functionalized clusters. The adsorbed Mo3S7 units were reduced on the TiO2 surface to generate an electrocatalyst that reduces the overpotential for the H2 evolution reaction by approximately 0.3 V (for 1 mA cm−2) with a turnover frequency as high as 1.4 s−1. The nature of the actual active molybdenum sulfide species has been investigated by X-ray photoelectron spectroscopy. In agreement with the electrochemical results, the modified TiO2 nanoparticles show a high photocatalytic activity for H2 production in the presence of Na2S/Na2SO3 as a sacrificial electron donor system.

Un argumento conocido es que las tecnologías de la información y las comunicaciones (TIC) han creado una brecha digital creciente entre las economías maduras y la de los países de menor desarrollo relativo. A su vez, se plantea con carácter de paradigma, que esta tendencia podría revertirse con la incorporación de incentivos al desarrollo local de industrias TIC en los países menos desarrollados. En los últimos años muchos gobiernos de países en vías de industrialización prestan creciente atención al desarrollo de industrias TIC en sus territorios. En esa promoción se observa, sin embargo, la persistencia de un viejo debate sobre las opciones de aplicar un fuerte “impulso masivo”, o impulsos “hacia adelante” y “hacia atrás”. Por ello resulta de gran interés el estudio de casos exitosos de desarrollo local de empresas TIC que permitan interpretar la naturaleza de las políticas de promoción y el impacto en cuanto a: (i) generación y fortalecimiento de eslabonamientos, con los proveedores, por un lado, y con la demanda, por el otro, (ii) diferenciación según el carácter nacional o multinacional de las empresas impulsoras, (iii) papel de las universidades e institutos de investigación, (iv) efectos sobre la generación de empleo directo e indirecto. Esta propuesta asume que existe la necesidad de comprender mejor el impacto del desarrollo local de ofertas TIC, la interrelación entre firmas locales, firmas locales y multinacionales y entre todas estas, y la capacidad doméstica de investigación, desarrollo e inversión. Un corpus de conocimiento de esta naturaleza es indispensable para que los responsables puedan diseñar las políticas públicas de incentivos adecuadas para generar los estímulos apropiados y contribuir al fortalecimiento del sector. Bajo este enfoque, es que el objetivo general del proyecto es investigar el impacto, en Córdoba, del paradigma TIC en la generación de una oferta local de firmas que elaboran productos y desarrollan servicios TIC, a partir de decisiones empresariales independientes, o como parte de una cadena productiva en la cual interviene una variedad de firmas locales e internacionales. La investigación estará centrada, por una parte, en el estudio de la evolución de los ordenamientos institucionales y legales para la promoción del sector TIC en el país y en Córdoba, y, por la otra, se focalizará en el análisis de los datos de fuente primaria sobre las firmas radicadas en el Gran Córdoba, que elaboran productos y desarrollan servicios TIC. El abordaje conjunto de ambos planos de análisis, permitirá contrastar la principal hipótesis de investigación que postula que, si se proveen entornos adecuados, orientados a facilitar los medios para superar las restricciones económicas, sociales, legales e institucionales, es posible lograr el desarrollo de cadenas productivas de firmas TIC, que generan impacto positivo en el medio local – principalmente el empleo - e integran a firmas domésticas y multinacionales, a centros de investigación, e incluso, a organizaciones de consumidores. Una segunda hipótesis a ser contratada en el trabajo, es que el desarrollo TIC en la provincia de Córdoba respondió a una estrategia de fuerte impulso masivo y servirá como evidencia empírica que contribuya al debate teórico sobre el tema. En la metodología se prevé realizar una recopilación de datos de fuentes secundarias del sector público y privado, a partir de la cual se elaborará un marco general para llevar a cabo la recolección de datos de fuentes primarias, mediante un conjunto de entrevistas en profundidad a informantes calificados y una encuesta a empresas TIC, nacionales y multinacionales, radicadas en el Gran Córdoba. El tratamiento y análisis de los datos comprenderá la elaboración de tablas, gráficos y cálculo de correlaciones e indicadores descriptivos, como así también la aplicación de modelos econométricos de riesgo y de supervivencia con fines predictivos. Los procesamientos se realizarán con el soft STATA.

Este trabalho aborda o tema dos clusters industriais - concentrações geográficas de empresas interligadas, fornecedores de produtos e serviços, empresas em setores afins e entidades que lhes estão associadas, como as universidades, entidades públicas, associações empresariais. A competitividade resulta da ação das empresas, e estas devem competir e cooperar para criar lucro económico, mas também gerar benefícios para a região e o país. O objetivo deste trabalho é demonstrar que a aplicação da teoria dos clusters no nosso país, - introduzida na sequência de um estudo pedido em 1994 ao criador desta teoria, o Dr. Michael Porter – teve efeitos muito positivos no desenvolvimento dos últimos 20 anos e que maiores poderiam ter sido esses efeitos, se tivesse sido feita a sua aplicação em todos os setores em que se identificavam vantagens competitivas da nossa economia. Foi realizada uma análise da evolução do mais reconhecido cluster, o da indústria do calçado, cujos resultados apontam para as estratégias a adotar em muitos outros setores da nossa economia. Numa extrapolação, fica claro que as regiões nacionais e os países que contam com clusters industriais são aqueles que apresentam desempenho superior, em termos de intensidade exportadora e valor acrescentado. Estas zonas apresentam ainda níveis elevados de riqueza e longevidade dos seus cidadãos. Em termos europeus, a Alemanha, que tem como grandes clusters os setores automóvel, da automação, da eletrónica e da pesquisa laboratorial, é o melhor exemplo deste facto.

Background: Adolescent depression prevention research has focused on mean intervention outcomes, but has not considered heterogeneity in symptom course. Here, we empirically identify subgroups with distinct trajectories of depressive symptom change among adolescents enrolled in two indicated depression preven- tion trials and examine how cognitive-behavioral (CB) interventions and baseline predictors relate to trajectory membership. Methods: Six hundred thirty-one participants were assigned to one of three conditions: CB group intervention, CB bibliotherapy, and brochure control. We used group-based trajectory modeling to identify trajectories of depressive symptoms from pretest to 2-year follow-up. We examined associations between class membership and conditions using chi- square tests and baseline predictors using multinomial regressions. Results: We identified four trajectories in the full sample. Qualitatively similar trajectories were found in each condition separately. Two trajectories of positive symptom course (low-declining, high-declining) had declining symptoms and were dis- tinguished by baseline symptom severity. Two trajectories of negative course (high-persistent, resurging), respectively, showed no decline in symptoms or de- cline followed by symptom reappearance. Participants in the brochure control condition were significantly more likely to populate the high-persistent trajectory relative to either CB condition and were significantly less likely to populate the low-declining trajectory relative to CB group. Several baseline factors predicted trajectory classes, but gender was the most informative prognostic factor, with males having increased odds of membership in a high-persistent trajectory rel- ative to other trajectories. Conclusions: Findings suggest that CB preventive interventions do not alter the nature of trajectories, but reduce the risk that adolescents follow a trajectory of chronically elevated symptoms.

The analysis of clusters has attracted considerable interest over the last few decades. The articulation of clusters into complex networks and systems of innovation -- generally known as regional innovation systems -- has, in particular, been associated with the delivery of greater innovation and growth. However, despite the growing economic and policy relevance of clusters, little systematic research has been conducted into their association with other factors promoting innovation and economic growth. This article addresses this issue by looking at the relationship between innovation and economic growth in 152 regions of Europe during the period between 1995 and 2006. Using an econometric model with a static and a dynamic dimension, the results of the analysis highlight that: a) regional growth through innovation in Europe is fundamentally connected to the presence of an adequate socioeconomic environment and, in particular, to the existence of a well-trained and educated pool of workers; b) the presence of clusters matters for regional growth, but only in combination with a good ‘social filter’, and this association wanes in time; c) more traditional R&D variables have a weak initial connection to economic development, but this connection increases over time and, is, once again, contingent on the existence of adequate socioeconomic conditions.

The objective of this research is to present cluster initiative approaches in post industrial regions characterized by similar economic history and challenges, with additional emphasis on their role in promoting innovation among regional businesses. The research is based on a comparison study of two environmental industry clusters: Environmental Technology Cluster (ET) from British West Midlands and ACLIMA from Spanish Basque Country. The study analyzes clusters' design and their role in fostering innovation based on environment industry clusters. In both regions environmental industry clusters represent strong potential for further dynamic development with grow opportunities driven by legislation introduced at EU, national or regional levels. The paper compares clusters' heterogeneity, goals and priorities, financing schemes, management structure, types of projects, character of private-public partnerships, challenges, as well as clusters' collaboration at regional/national/international levels. Also focus is given on how the clusters enhance innovation and what types of projects are executed by the regions in this field.

While many studies of franchising have examined the organizational antecedents of internationalization, few have examined how differences among markets lead to this internationalization. Studies linking environmental factors to the companies' decision to internationalize showed that various political, social and economic factors either attract or repel international franchising investment. We build on these studies' selected variables to understand the similarities and differences among international franchising markets. Using these variables, our results show that countries divide into eight clusters with similar international franchising market characteristics. A discussion of each cluster follows with implications for franchising research.
