Relación entre responsabilidad social y performance en las pequeñas y medianas empresas: Revisión bibliográfica

El interés suscitado por la responsabilidad social en el ámbito académico y profesional ha provocado que la misma sea objeto de discusión continua en multitud de foros. No obstante, su focalización evidencia un desarrollo desigual entre el ámbito de las grandes corporaciones y el de las Pequeñas y Medianas Empresas (pymes). Por ello, con la intención de contribuir al estudio de la Responsabilidad Social Empresarial (RSE) en el ámbito de las pymes, se ha llevado a cabo una revisión de aquellos trabajos que, tomando como muestra este tipo de organizaciones, han examinado la incidencia que determinados factores tienen en la adopción de un comportamiento socialmente responsable o cómo el desarrollo de prácticas sostenibles afecta al performance organizativo desde una perspectiva financiera. El análisis realizado permite corroborar cómo la figura del propietario gestor, con sus valores y creencias éticas, desempeña un papel fundamental en las elecciones estratégicas propias de un comportamiento sostenible y cómo la gestión responsable de las relaciones con los stakeholders incide positivamente sobre el performance. Aun cuando, como en toda revisión literaria, la búsqueda bibliográfica está sujeta a unos criterios subjetivos, los documentos seleccionados y los empleados de manera complementaria señalan dos posibles vías para incentivar la ejecución de prácticas sostenibles: reelaborar la normativa legal y ofrecer evidencias suficientes de cómo un comportamiento responsable puede originar mejoras competitivas.

Evolución geodinámica del Macizo Ibérico meridional (Zona de Ossa-Morena y Zona Centro Ibérica). XXV Reunión de la Comisión de Tectónica de la SGE (Sociedad Geológica de España)

La evolución geodinámica de zonas poliorogénicas es tanto más difícil cuanto más fragmentarios son los datos cartográficos que impiden correlacionar segmentos diferentes. Un buen ejemplo de ello son los numerosos modelos evolutivos y reconstrucciones paleogeográficas propuestos para la cadena hercínica. En el Macizo Ibérico la correlación entre áreas se ha intentado resolver con subdivisiones en zonas similares a las propuestas para otros macizos variscos. En las zonas más complejas se optó por una subdivisión en “Dominios”, a los que se llegó a equiparar con “terrenos” independientes, con evoluciones geodinámicas poco o nada relacionables. Un buen ejemplo de ello son las diversas propuestas de subdivisión de la Zona de Ossa-Morena, reflejo de las deficiencias cartográficas y de la dificultad de correlacionar cartografías anejas, delineándose mapas de difícil interpretación y leyendas muy complicadas con centenares de términos. Durante los últimos 10 años un equipo de la Universidad de Extremadura y la Universidad del País Vasco ha revisado sistemáticamente la cartografía geológica de Extremadura, obteniéndose un mapa continuo con una leyenda única, en la que todos los materiales están debidamente diferenciados, correlacionados y muchos de ellos datados. Este trabajo ha supuesto la culminación de más de 35 años dedicados de forma ininterrumpida a la investigación y cartografía geológica del Macizo Ibérico meridional. Ello ha permitido proponer una subdivisión mucho más sencilla y poner de manifiesto la falta de significado de la subdivisiones en Dominios y Unidades existentes en distintos trabajos.

Uptake and factors that influence the use of 'sit less, move more' occupational intervention strategies in Spanish office employees

Background: Little is known about the types of 'sit less, move more' strategies that appeal to office employees, or what factors influence their use. This study assessed the uptake of strategies in Spanish university office employees engaged in an intervention, and those factors that enabled or limited strategy uptake. Methods: The study used a mixed method design. Semi-structured interviews were conducted with academics and administrators (n = 12; 44 +/- 12 mean SD age; 6 women) at three points across the five-month intervention, and data used to identify factors that influenced the uptake of strategies. Employees who finished the intervention then completed a survey rating (n = 88; 42 +/- 8 mean SD age; 51 women) the extent to which strategies were used [never (1) to usually (4)]; additional survey items (generated from interviewee data) rated the impact of factors that enabled or limited strategy uptake [no influence (1) to very strong influence (4)]. Survey score distributions and averages were calculated and findings triangulated with interview data. Results: Relative to baseline, 67% of the sample increased step counts post intervention (n = 59); 60% decreased occupational sitting (n = 53). 'Active work tasks' and 'increases in walking intensity' were the strategies most frequently used by employees (89% and 94% sometimes or usually utilised these strategies); 'walk-talk meetings' and ` lunchtime walking groups' were the least used (80% and 96% hardly ever or never utilised these strategies). 'Sitting time and step count logging' was the most important enabler of behaviour change (mean survey score of 3.1 +/- 0.8); interviewees highlighted the motivational value of being able to view logged data through visual graphics in a dedicated website, and gain feedback on progress against set goals. 'Screen based work' (mean survey score of 3.2 +/- 0.8) was the most significant barrier limiting the uptake of strategies. Inherent time pressures and cultural norms that dictated sedentary work practices limited the adoption of 'walk-talk meetings' and ` lunch time walking groups'. Conclusions: The findings provide practical insights into which strategies and influences practitioners need to target to maximise the impact of 'sit less, move more' occupational intervention strategies.

Patterns of Impact Resulting from a 'Sit Less, Move More' Web-Based Program in Sedentary Office Employees

Purpose Encouraging office workers to 'sit less and move more' encompasses two public health priorities. However, there is little evidence on the effectiveness of workplace interventions for reducing sitting, even less about the longer term effects of such interventions and still less on dual-focused interventions. This study assessed the short and mid-term impacts of a workplace web-based intervention (Walk@WorkSpain, W@WS; 2010-11) on self-reported sitting time, step counts and physical risk factors (waist circumference, BMI, blood pressure) for chronic disease. Methods Employees at six Spanish university campuses (n=264; 42 +/- 10 years; 171 female) were randomly assigned by worksite and campus to an Intervention (used W@WS; n=129; 87 female) or a Comparison group (maintained normal behavior; n=135; 84 female). This phased, 19-week program aimed to decrease occupational sitting time through increased incidental movement and short walks. A linear mixed model assessed changes in outcome measures between the baseline, ramping (8 weeks), maintenance (11 weeks) and follow-up (two months) phases for Intervention versus Comparison groups. Results A significant 2 (group) x 2 (program phases) interaction was found for self-reported occupational sitting (F[3]=7.97, p=0.046), daily step counts (F[3]=15.68, p=0.0013) and waist circumference (F[3]=11.67, p=0.0086). The Intervention group decreased minutes of daily occupational sitting while also increasing step counts from baseline (446 +/- 126; 8,862 +/- 2,475) through ramping (+425 +/- 120; 9,345 +/- 2,435), maintenance (+422 +/- 123; 9,638 +/- 3,131) and follow-up (+414 +/- 129; 9,786 +/- 3,205). In the Comparison group, compared to baseline (404 +/- 106), sitting time remained unchanged through ramping and maintenance, but decreased at follow-up (-388 +/- 120), while step counts diminished across all phases. The Intervention group significantly reduced waist circumference by 2.1cms from baseline to follow-up while the Comparison group reduced waist circumference by 1.3cms over the same period. Conclusions W@WSis a feasible and effective evidence-based intervention that can be successfully deployed with sedentary employees to elicit sustained changes on "sitting less and moving more".

An approach version of fuzzy metric spaces including an ad hoc fixed point theorem

In this paper, inspired by two very different, successful metric theories such us the real view-point of Lowen's approach spaces and the probabilistic field of Kramosil and Michalek's fuzzymetric spaces, we present a family of spaces, called fuzzy approach spaces, that are appropriate to handle, at the same time, both measure conceptions. To do that, we study the underlying metric interrelationships between the above mentioned theories, obtaining six postulates that allow us to consider such kind of spaces in a unique category. As a result, the natural way in which metric spaces can be embedded in both classes leads to a commutative categorical scheme. Each postulate is interpreted in the context of the study of the evolution of fuzzy systems. First properties of fuzzy approach spaces are introduced, including a topology. Finally, we describe a fixed point theorem in the setting of fuzzy approach spaces that can be particularized to the previous existing measure spaces.

Proteomic Analysis of the Ubiquitin Landscape in the Drosophila Embryonic Nervous System and the Adult Photoreceptor Cells

Background Ubiquitination is known to regulate physiological neuronal functions as well as to be involved in a number of neuronal diseases. Several ubiquitin proteomic approaches have been developed during the last decade but, as they have been mostly applied to non-neuronal cell culture, very little is yet known about neuronal ubiquitination pathways in vivo. Methodology/Principal Findings Using an in vivo biotinylation strategy we have isolated and identified the ubiquitinated proteome in neurons both for the developing embryonic brain and for the adult eye of Drosophila melanogaster. Bioinformatic comparison of both datasets indicates a significant difference on the ubiquitin substrates, which logically correlates with the processes that are most active at each of the developmental stages. Detection within the isolated material of two ubiquitin E3 ligases, Parkin and Ube3a, indicates their ubiquitinating activity on the studied tissues. Further identification of the proteins that do accumulate upon interference with the proteasomal degradative pathway provides an indication of the proteins that are targeted for clearance in neurons. Last, we report the proof-of-principle validation of two lysine residues required for nSyb ubiquitination. Conclusions/Significance These data cast light on the differential and common ubiquitination pathways between the embryonic and adult neurons, and hence will contribute to the understanding of the mechanisms by which neuronal function is regulated. The in vivo biotinylation methodology described here complements other approaches for ubiquitome study and offers unique advantages, and is poised to provide further insight into disease mechanisms related to the ubiquitin proteasome system.

Magnetoresistance at artificial interfaces in the itinerant SrRuO3 ferromagnet

The magnetoresistance across interfaces in the itinerant ferromagnetic oxide SrRuO3 have been studied. To define appropriately the interfaces, epitaxial thin films have been grown on bicrystalline and laser-patterned SrTiO3 substrates. Comparison is made with results obtained on similar experiments using the double-exchange ferromagnetic oxide La2/3Sr1/3MnO3. It is found that in SrRuO3, interfaces induce a substantial negative magnetoresistance, although no traces of the low-field spin tunneling magnetoresistance are found. We discuss these results on the basis of the distinct degree of spin polarization in ruthenates and manganites and the different nature of the surface magnetic layer formed at interfaces.
