El debate como herramienta de aprendizaje
En el texto se presenta la experiencia derivada de la implementación del proyecto de innovación docente titulado. El debate como herramienta de aprendizaje. Con este proyecto se pretendía crear una experiencia de participación activa de los estudiantes en un recurso educativo: la realización de debates como herramienta para el aprendizaje. La utilización del debate puede ser una estrategia muy útil para el desarrollo intelectual del estudiante y para conectar los temas que se tratan en la universidad con los problemas sociales. De este modo la formación que recibe el alumnado va más allá de la mera adquisición de conocimientos y entronca directamente con el paradigma actual que entiende la universidad como una institución en la que se proporciona una formación integral a los estudiantes
The role of absorptive capacity and organizational unlearning in the link between social media and service dominant orientation
Purpose – This paper aims to study the relationship between the knowledge obtained in social networks
by firms together with the firms’ knowledge absorptive capacity and organizational unlearning as
influencers of service-dominant (S-D) orientation, as well as the mediating role of absorption capacity and
organizational unlearning in this process.
Design/methodology/approach – The sample amounts to 101 responding companies, obtained from
the SABI database. The companies belong to the service sector in Spain and have at least 50 employees
and 5 years or more of existence in the market. The model was estimated through partial least squares
structural equation modeling with smartPLS software 3.2.6.
Findings – The results show that the use of social media is very important for firms to acquire knowledge
and capabilities that help them to become S-D oriented. In addition, absorptive capacity and unlearning
processes are dynamic capabilities necessary to transform the knowledge acquired in social media and
to become S-D oriented.
Research limitations/implications – Companies’ managers draw conclusions that can generate great
value, while better meeting the needs and desires of the market, the more knowledge is obtained. In
addition, the use of the knowledge generated in this process will reduce the risk of sudden changes in the
market.
Practical implications – The more knowledge is gained using social networks, the better the companies’
managers will be able to draw conclusions that can generate great value, while at the same time better
satisfying the needs and desires of the market, and thus create capacities that allow the company to be
service-oriented. In addition, the use of these knowledge platforms strengthens the strategic advantage of
companies through the promotion of innovation and by relating dynamic capabilities with the orientation
toward sustainable development. As mentioned above, a process will be generated that will reduce the risk
of sudden changes in the market.
Originality/value – This is one of the few studies trying to study the antecedents of S-D orientation and
the first to study the direct effect of social media use, and the direct and indirect effect of absorptive
capacity and organizational unlearning on S-D orientation as dynamic capabilities.Foundation for Science and Technology UIDB/04630/202
Linking market orientation, innovation, unlearning and performance: A multiple mediation model.
Many studies uphold market orientation as a key factor in creating and sustaining a firm’s
competitive advantage. The present research model explores this topic further by including
within the model the links between organizations’ innovation outcomes, its process of
organizational unlearning and business performance. In particular, the model empirically tests
the mediating role of innovation outcomes and organizational unlearning in the relationship
between market orientation and business performance. The present study uses a sample of 145
firms from the Spanish automotive components manufacturing sector and employs partial
least squares (PLS) in order to test the research hypothese
Linking an unlearning context with firm performance through human capital
AbstractThe purpose of this paper is to examine the relationship among organisational unlearning, human capital and firm performance. In doing so, this paper comprehensively reviewed the literature on the unlearning concept, and developed and validated a model to measure unlearning in 112 companies listed on the Spanish Stock Exchange. The methodology involved the construction and analysis of a structural model using both subjective and objective criteria in our measurement variables, developed from a relevant literature review. Our findings show that managers need to develop an unlearning context process to create human capital, which is a primordial asset to improve firm performance
Exploring fitness centre consumer loyalty: differences of non-profit and low-cost business models in Spain
A number of studies have placed at the forefront variables that predict
the loyalty of clients in fitness centres. In fact, no study has analysed
the differences between these variables according to business
models. The objective of this study was to analyse the relationship
between quality, value, satisfaction and the future intentions of clients
of public and private low-cost fitness centres and their differences. A
questionnaire was administered to a sample of 1805 fitness centre
clients. A confirmatory factor analysis and multi-group analysis was
performed to test the difference between two invariance models. The
findings indicate a greater weight in facilities and employees of the
quality perceived from private low-cost fitness centres and a greater
weight in programmes from public fitness centres. Furthermore, the
relationship between the variables’ overall quality, perceived value,
satisfaction and future intentions had a greater influence in private
low-cost fitness centres than in public centres
La pobreza en América Latina: un análisis descriptivo del siglo XXI
La pobreza es un tema notable a nivel mundial y sobre todo para América Latina, siendo para las diferentes
administraciones un gran enigma aún sin zanjar. Son muchos los indicadores que existen para medirla, pero
ningún método es por sí solo suficiente, por lo que el uso combinado de los mismos puede ser la opción más
acertada para la cuantificación de la pobreza. Por ello, el objetivo de esta investigación es analizar y comparar
la pobreza, así como su evolución, en los países de América Latina desde el año 2000 hasta la actualidad.
Para lograrlo, se utiliza una serie de indicadores obtenidos del Banco Interamericano de Desarrollo (BID). De
un lado se compara el comportamiento, de manera indirecta, en términos de renta, y de otra se elabora un
índice, que de manera directa, mide el acceso a necesidades básicas de la población
Eficacia de la suplementación con β-hydroxy-β-methylbutyrate (HMB) en el deporte: actualización e implicación práctica
Introduction: although β-hydroxy-β-methylbutyrate
(HMB) is generally marketed as a supplement for increasing
muscle mass and strength, it is still not fully understood
how and in which particular sports and conditions
HMB can be more effective.
Aims: the primary purpose of this review is to update
and summarize the current knowledge about the usefulness
of HMB and to organize this information by different
sports with specific reference to sports with high
wear and tear phenomena as soccer, rugby or football.
Methods: a search was performed in PubMed database.
This review presents the results about HMB use in
sport.
Results: the articles identified in this review support
the notion that HMB could help to attenuate tissue catabolism
and initiate muscle anabolism particularly in untrained
individuals exposed to strenuous exercise or when
trained individual are exposed to periods of high physical
stress. HMB could therefore be applied in some specific
periods of athlete’s season where there are high-intensity
training periods, high density of competitions and little
recovery time between them, starting recovery phases
from an injury period and/or any other different situation
where performance or recovery could be affected by
a great catabolic environment.
Conclusion: this update contributes to clarify and define
possible mechanisms and/or effectiveness of HMB
supplementation related to endurance sports (i.e. cycling
and athletics), strength-power sports (i.e. resistance training,
football, rugby, soccer, judo, waterpolo and rowing)
and recreational activities.Introducción: aunque el β-hidroxi-β-metilbutirato
(HMB) se ha empleado generalmente como suplemento
para aumentar la masa muscular y la fuerza, es necesario
un mejor entendimiento de su función y averiguar en qué
deportes es más efectivo.
Objetivos: el objetivo principal de esta revisión es actualizar
y resumir el conocimiento existente en torno a la
utilización del HMB para clasificarla en función de cada
modalidad deportiva, con especial mención a aquellas
actividades con un alto grado de destrucción muscular,
como pueden ser el fútbol, el rugby o el fútbol americano.
Métodos: se utilizó la base de datos PubMed para la
búsqueda de artículos. Esta revisión presenta los resultados
sobre la utilización de HMB clasificados por deportes.
Resultados: la mayoría de los artículos seleccionados
sugieren que cuando una persona entrenada o no entrenada
se somete a un ejercicio intenso o diferente al habitual,
el HMB puede atenuar el catabolismo muscular
producido e iniciar los procesos anabólicos necesarios
para recuperar lo antes posible. De esta forma, el HMB
podría aplicarse en algunos momentos concretos de la
temporada deportiva en los que hubiera períodos con
entrenamientos de alta intensidad, o durante un periodo
con alta densidad competitiva y con poca recuperación
entre competiciones, o bien durante las primeras fases
de la readaptación física después de una lesión y/o durante
cualquier otra situación en la que el rendimiento o
la recuperación se pueden ver afectados por un entorno
altamente catabólico.
Conclusión: esta revisión pretende aclarar y definir
los posibles mecanismos por los que la suplementación
con HMB puede ser efectiva en deportes de resistencia
(ciclismo y carreras de fondo), en deportes de fuerza-potencia
(fútbol, yudo, waterpolo, remo, fútbol americano y
musculación) y en actividades deportivas recreacionales.This work was supported by the Andalusian Sports Medicine Centre (C.A.M.D.) through project no. EX-2005/07.

Adipose tissue-derived mesenchymal stem cells as a strategy to improve recovery after stroke
Introduction: Based on the positive results observed in experimental animal models, adipose
tissue-derived mesenchymal stem cells (AD-MSCs) constitute a promising therapy for stroke
treatment. However, several aspects need to be clarified to identify the optimal conditions for
successful clinical translation.
Areas covered: This review focuses on AD-MSC treatment for ischemic and hemorrhagic stroke
in experimental animal models. In addition, we will explore the optimization of treatment
conditions including AD-MSC production, administration routes and therapeutic windows for
their appropriate use in patients, and we will provide an update on clinical trials on this
therapy.
Expert opinion: Compared with other cell types, AD-MSCs have been less investigated in
stroke studies. Currently, experimental animal models have shown safety and efficacy with this
treatment after stroke. Due to several advantages of AD-MSCs, such as their abundance and
accessibility, they can be considered a promising strategy for use in patients. However, many
questions are still to be resolved regarding their mechanisms of action, immune system
modulation and the effects of AD-MSCs on all components of the brain that may be affected
after ischemic and hemorrhagic strokesThis project is supported by research grants PS12/01754 (Spanish Ministry of Science) and

Adipose Tissue and Inflammation
Adipose tissue is composed mainly by adipocytes and stromal-vascular fraction, which are composed by different cell types including macrophages. There are three types of adipose tissue: brown (BrAT), white (WAT), and beige (BeAT). BrAT is less abundant and is implicated in lipid oxidation and energy balance; BeAT has the pathway of adaptive thermogenesis, and WAT is endocrine in nature and lipid storage site and is implicated as an endocrine organ that secretes hormones and different molecules. These molecules are pro-inflammatory and anti-inflammatory factors, including the adipokines leptin, adiponectin, resistin, and visfatin, as well as cytokines and chemokines, such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, leptin, adiponectin, and others, are involved with the development of adipose tissue inflammation and obesity. This pathological condition, together with other factors such as oxidative stress, may develop insulin resistance and the pathogenesis of type 2 diabetes mellitus (T2DM)
El Greenwashing o como destapar estrategias comerciales de ventas falsas que se apoyan en una filosofía "verde"
En nuestro trabajo partimos del estudio de la forma en que las empresas utilizan el Green Marketing en su estrategia comercial, y como lo “verde” se integra como una filosofía que está impregnada en la cultura empresarial de la organización. Partiendo de lo anterior, hemos descubierto que en muchos períodos esta estrategia verde es un argumento para obtener mejores resultados, más que una idea interiorizada en la organización, a esto es lo que denominamos Greenwashing. A lo largo del artículo hemos revisado la literatura que existe sobre el tema objeto de estudio, y como resultado hemos desarrollado un completo modelo teórico utilizando las variables más relevantes encontradas en esta investigación, y que mejor pueden estudiar este fenómeno del Greenwashing.In our work, we start from the study of how companies use Green Marketing in their business strategy, and how the "green" is integrated as a philosophy that is impregnated in the business culture of the organization. Based on the above, we have discovered that in many periods, this green strategy is an argument for better results, rather than an idea internalized in the
organization, this is what we call Greenwashing. Throughout the article we have reviewed the literature that exists on the subject under study, and as a result we have developed a complete theoretical model using the most relevant variables found in this research, and that can best study this Greenwashing phenomenon
