    Inter-firm cooperation and innovation: The role of strategic alliances

    Get PDF
    The relationship between inter-firm cooperation and downscaling, outsourcing and multiple firm strategic alliances is explored conceptually and with data from innovative firms. Downscaling is related to cooperative outsourcing as a significant influence shaping inter- firm relations. Embedding cooperative outsourcing in interfirm strategic alliances is advantageous, particularly for small and medium-size firms. Network structures within alliances are important to consider, however, since they hold the key not only to the division of labour within an alliance, but also to the longevity of the alliance, cooperation, and the relations of trust that pervade transactions.

    [EN] The main aim of this study was to analyze the scientific productivity and collaboration between Old World wine-producing countries (Austria, Bulgaria, France, Germany, Greece, Hungary, Italy, Portugal, Romania, Spain, Switzerland) and New World wine-producing countries (Argentina, Australia, Brazil, Canada, Chile, Mexico, New Zealand, Peru, South Africa, United Sates, Uruguay) in viticulture and oenology through bibliometric analyses of articles included in the Science Citation Index Expanded database for the period 1994-2013. A number of 1527 research articles were published in 563 journals. The results highlight an important growth in the collaboration between countries during the second decade (2004-2013). Papers have been published in numerous journals belonging to several subject areas. Food Science and Technology, Horticulture and Biotechnology and Applied Microbiology appeared as the most productive research areas. A social network analysis of collaboration between these countries was also performed in order to analyze the most powerful scientific cooperation. (C) 2016 Elsevier Ltd.

    Declared experiences of risky sexual behaviors in relation to alcohol consumption in the first year of college

    Get PDF
    Fundamentos: En universitarios, el consumo de alcohol de mayor riesgo (borracheras y binge drinking (BD), tiene consecuencias negativas sobre su desarrollo y probablemente facilita conductas sexuales de riesgo. El objetivo de este trabajo fue estudiar si las conductas sexuales de riesgo al consumir alcohol (CSRA) se asocian a los consumos de mayor riesgo. Métodos: Estudio multicéntrico transversal con datos del Proyecto uniHcos, de universitarios de 1er año de 11 universidades españolas, entre los cursos 2011-2012 y 2017- 2018. Datos recogidos mediante cuestionario autoadministrado. Se realizó un análisis uni y bivariable, evaluando la significación estadística de las diferencias de prevalencia con chi-cuadrado. Se utilizó media y desviación típica para variables cuantitativas y como estadístico de contraste t de Student. Resultados: 9.862 participantes (72,2% mujeres). El 90,3% consumió alcohol y el 60,9% tuvo borracheras en último año; el 49% tuvo BD en el último mes. El consumo en el último mes y las borracheras fueron mayores en hombres y < 21 años. Las CSRA fueron superiores entre los que se emborracharon (15,7% sexo sin protección, 1,9% abuso sexual y 0,7% aprovecharse sexualmente) y consumieron en BD (17,1%, 1,9% y 0,7%). Las mujeres con ambos consumos de riesgo presentaron más abusos sexuales (2,2%), y los hombres fueron quienes más se aprovecharon sexualmente de otros (borracheras:1,2%; BD: 1,3%). Conclusiones: El consumo de alcohol está por encima de grupos similares. El BD tiene un patrón similar por género y edad. Las CSRA se asocian a los consumos de mayor riesgo, no detectándose en este grupo diferencias por género en sexo sin protección, sí en otras CSRA.Objective: In college students, higher risk alcohol consumption (drunkenness and binge drinking-BD) has negative consequences on their development and and probably facilitates risk sexual behaviors. The objective was to study if risky sexual behaviors when consuming alcohol (RSBA) are associated with higher risk consumption. Methods: Cross-sectional multicenter study with UniHcos Project, 1st year university students from 11 universities in Spain, academic years 2011-2012 to 2017-2018 data. This data were collected by self-administered questionnaire. A uni and bivariate analysis was performed, evaluated the statistical significance of the differences in prevalence with chi-square. Mean and standard deviation were used for quantitative variables and Student's t test statistic was used. Results: 9,862 subjects (72.2% women). 90.3% reported having consumed alcohol and 60.9% had drunk the last year, 49% BD in last month. It was deteded in men, significantly higher consumption in the last month and drunkenness. Last month consumption and drunkenness were significantly higher in men and in <21 years. The RSBA were significantly higher among who were drunk (15.7% unprotected sex, 1.9% sexual abuse and 0.7% taking sexual advantage) and had BD (17.1%, 1.9% and 0.7 %). Women with both risk consumptions had more sexual abuse (2.2%), and men had greater behaviors of taking sexual advantage of someone (drunk: 1.2%; BD: 1.3%). Conclusions: Alcohol consumption was above similar groups. BD consumption was similar by gender and age. Risk sexual behaviors appear mainly in problematic consumption. Gender differences are not detected in alcohol consumers in unprotected sex but deteded in the rest.Financiación: El estudio ha sido financiado por el Plan Nacional Sobre Drogas del Ministerio de Salud, Servicios Sociales e Igualdad.

    Technology and feminism : a strange couple

    Get PDF
    The "gender digital divide" constitutes a prolific research program that compares the differences between women and men in access to Information and Communication Technologies (ICT). Nevertheless, those using feminist socio-constructivist perspectives argue for the need to pay attention, not only to "access," but also to "design," in addition to considering social relations as something that is coded within technological artifacts. From this perspective, gender constitutes an integral part of technological production. This paper explores the co-constitution of gender and technology, considering a specific action-research experience. It is argued that the re-signification of gendered and technological codes drifts through: a) the opening of gendered and technological codes; b) the production of new cultural imaginaries that question hegemonic representations of gender; and c) the production of new subjectivities through the reorganization of socio-technical practices to develop performative acts that transform patriarchal relationsLa "brecha digital de género" constituye un prolífico programa de investigación que compara las diferencias entre mujeres y hombres en el acceso a las Tecnologías de Información y Comunicación. Las perspectivas socio-constructivistas feministas, sin embargo, abogan por la necesidad de prestar atención no sólo al "acceso", sino también al "diseño", y consideran las relaciones sociales como elementos codificados en el interior los artefactos tecnológicos. Desde esta perspectiva, el género constituye una parte integral de la producción tecnológica. Este trabajo explora la constitución conjunta de género y tecnología a partir de una experiencia de investigación-acción específica. Se argumenta que la resignificación de los códigos de género y tecnológicos se desplaza a través de: a) la apertura de los códigos de género y tecnológicos; b) la producción de nuevos imaginarios culturales que cuestionan las representaciones hegemónicas de género; y c) la producción de nuevas subjetividades a través de la reorganización de las prácticas socio-técnicas para el desarrollo de actos performativos que transforman las relaciones patriarcales

    Multi-messenger observations of a binary neutron star merger

    On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta

    Pooled analysis of WHO Surgical Safety Checklist use and mortality after emergency laparotomy

    Background The World Health Organization (WHO) Surgical Safety Checklist has fostered safe practice for 10 years, yet its place in emergency surgery has not been assessed on a global scale. The aim of this study was to evaluate reported checklist use in emergency settings and examine the relationship with perioperative mortality in patients who had emergency laparotomy. Methods In two multinational cohort studies, adults undergoing emergency laparotomy were compared with those having elective gastrointestinal surgery. Relationships between reported checklist use and mortality were determined using multivariable logistic regression and bootstrapped simulation. Results Of 12 296 patients included from 76 countries, 4843 underwent emergency laparotomy. After adjusting for patient and disease factors, checklist use before emergency laparotomy was more common in countries with a high Human Development Index (HDI) (2455 of 2741, 89.6 per cent) compared with that in countries with a middle (753 of 1242, 60.6 per cent; odds ratio (OR) 0.17, 95 per cent c.i. 0.14 to 0.21, P <0001) or low (363 of 860, 422 per cent; OR 008, 007 to 010, P <0.001) HDI. Checklist use was less common in elective surgery than for emergency laparotomy in high-HDI countries (risk difference -94 (95 per cent c.i. -11.9 to -6.9) per cent; P <0001), but the relationship was reversed in low-HDI countries (+121 (+7.0 to +173) per cent; P <0001). In multivariable models, checklist use was associated with a lower 30-day perioperative mortality (OR 0.60, 0.50 to 073; P <0.001). The greatest absolute benefit was seen for emergency surgery in low- and middle-HDI countries. Conclusion Checklist use in emergency laparotomy was associated with a significantly lower perioperative mortality rate. Checklist use in low-HDI countries was half that in high-HDI countries.Peer reviewe

    En Colombia, actualmente no existen parámetros claros para el diagnóstico de pacientes con talla baja, ni sobre el tratamiento de esta población con hormona de crecimiento recombinante humana (somatropina), lo cual se ve favorecido por la diversidad de programas de formación de profesionales en endocrinología pediátrica. En respuesta a esta problemática se realizó el primer acuerdo colombiano de expertos en talla baja liderado por la Asociación Colegio Colombiana de Endocrinología Pediátrica (ACCEP); este trabajo contó con la participación y el aval de expertos clínicos de importantes instituciones de salud públicas y privadas del país, además de expertos metodológicos del instituto Keralty, quienes garantizaron la estandarización del uso de la somatropina. Después de realizar una minuciosa revisión de la literatura, se propone la unificación de definiciones, un algoritmo diagnóstico, los parámetros de referencia de las pruebas bioquímicas y dinámicas, una descripción de las consideraciones de uso de la somatropina para el tratamiento de las patologías con aprobación por la entidad regulatoria de medicamentos y alimentos en Colombia y, por último, un formato de consentimiento informado y de ficha técnica del medicamento.In Colombia there are no guidelines for diagnosis and management of patients with short stature and for the use of recombinanthuman growth hormone, mainly caused by the diversity of training centers in pediatric endocrinology. In response to this situation,the Asociación Colegio Colombiana de Endocrinología Pediátrica leds the first colombian short stature expert committee in order tostandardize the use of human recombinant growth hormone. This work had the participation and endorsement of a consortium ofclinical experts representing the Sociedad Colombiana de Pediatría, Secretaría Distrital de Salud de Bogotá- Subred Integrada deServicios de Salud Suroccidente, Fundación Universitaria Sanitas, Universidad de los Andes and some public and private healthinstitutions in the country, in addition to the participation of methodological experts from the Instituto Global de Excelencia ClínicaKeralty. By reviewing the literature and with the best available evidence, we proposed to unify definitions, a diagnostic algorithm,biochemical and dynamic tests with their reference parameters, a description of the considerations about growth hormone use amongthe indications approved by regulatory agency for medications and food in Colombia and finally a proposal for an informed consentand a medication fact sheet available for parents and patients.https://orcid.org/0000-0002-7856-7213https://orcid.org/0000-0003-2241-7854Revista Nacional - Indexad
