Sobre el concepto y medida del tecnoestrés: una revisión

Vuitenes Jornades de Foment de la Investigació de la FCHS (Any 2002-2003)El presente trabajo pretende analizar los procesos de adaptación de las personas al uso continuado de las tecnologías de la información y comunicación (los sistemas, servicios, infraestructura o tecnologías propias de la información) en el mundo laboral y/o educativo superior. Las tecnologías de la información y la comunicación hacen más fácil el trabajo y la forma de vivir, pero también pueden producir efectos adversos como el “tecnoestrés”. El tecnoestrés puede caracterizarse por la ansiedad y/o renuncia para aceptar la tecnología. En nuestro trabajo analizamos el tecnoestrés considerándolo como un estado psicológico negativo asociado a la exposición a la tecnología y que genera un desajuste entre demandas y recursos laborales y/o personales (relacionados siempre con la tecnología). El tecnoestrés surge como resultado de una valoración subjetiva de las exigencias del entorno laboral y en concreto del uso de las nuevas tecnologías y presenta las siguientes dimensiones: Autoeficacia específica baja, distres (ansiedad hacia la tecnología); y actitudes negativas hacia las mismas. Se presentan finalmente aplicaciones prácticas y posibles desarrollos futuros en la investigación sobre el tema

Covid key figures and new challenges in the horeca sector: the way towards a new supply-chain

The profound impact of the coronavirus pandemic on global tourism activity and the hospitality industry has rendered statistical approaches on tourism-demand forecasting obsolete. Furthermore, literature review shows the absence of studies on the supply chain in the HoReCa (hotel, restaurant, catering) sector from a sustainability perspective that also addresses economic and social aspects, and not only environmental ones. In this context, the objective of this article is to carry out a prospective analysis on how the changes in the behaviour of consumers during the pandemic and the uncertainties regarding the exit from the health emergency can give rise to social trends with a high impact on the HoReCa sector in the coming years and, specifically, how they will affect the HoReCa supply chain. In the absence of investigations due to the proximity of what has happened, public sources and reports of international relevance have been identified and analysed from the future studies and strategic and competitive intelligence disciplines. The HoReCa sector in Spain has been chosen as field of observation. This analysis draws the future of the HoReCa sector, describes the changes in customer behaviour regarding food and beverages, explains the changes in distribution chains, and reflects on the impact of potential scenarios on the sector. The confluence of all these changes and trends can even configure a new supply chain in the hospitality sector with the emergence of new actors and the increase of access routes to a new final customer for whom security prevails in all its dimensions: physical, emotional, economic, and digital

Glucocorticoid treatment and endocrine pancreas function: implications for glucose homeostasis, insulin resistance and diabetes

Glucocorticoids (GCs) are broadly prescribed for numerous pathological conditions because of their anti-inflammatory, antiallergic and immunosuppressive effects, among other actions. Nevertheless, GCs can produce undesired diabetogenic side effects through interactions with the regulation of glucose homeostasis. Under conditions of excess and/or long-term treatment, GCs can induce peripheral insulin resistance (IR) by impairing insulin signalling, which results in reduced glucose disposal and augmented endogenous glucose production. In addition, GCs can promote abdominal obesity, elevate plasma fatty acids and triglycerides, and suppress osteocalcin synthesis in bone tissue. In response to GC-induced peripheral IR and in an attempt to maintain normoglycaemia, pancreatic β-cells undergo several morphofunctional adaptations that result in hyperinsulinaemia. Failure of β-cells to compensate for this situation favours glucose homeostasis disruption, which can result in hyperglycaemia, particularly in susceptible individuals. GC treatment does not only alter pancreatic β-cell function but also affect them by their actions that can lead to hyperglucagonaemia, further contributing to glucose homeostasis imbalance and hyperglycaemia. In addition, the release of other islet hormones, such as somatostatin, amylin and ghrelin, is also affected by GC administration. These undesired GC actions merit further consideration for the design of improved GC therapies without diabetogenic effects. In summary, in this review, we consider the implication of GC treatment on peripheral IR, islet function and glucose homeostasis.This study was supported by grants from the Spanish foundations Ministry of Science and Innovation (BFU2013-42789; BFU2011-28358)This study was supported by grants from the European Foundation for the Study of Diabetes (EFSD / BI Basic Program and the Albert Renold Fellowship)This study was supported by grants from the Brazilian National Council for Scientific and Technological Development (CNPq 471397 / 2011-3

Reactivando la Ciudad Fallera

Spanish fact-checking services: an approach to their business models

The proliferation of fact-checking services is a fast-growing global phenomenon, especially in Western countries. These services are the response of journalism to disinformation, that has transformed a common internal procedure of journalistic work in the core of a business directed to the general public, also offered to the companies of mass media and social media. Literature review shows that the research on fact-checking has focused on the origin, funding, relationship with the media, procedures, and experiences related to politics and COVID-19. However, the ownership structure of the fact-checking services has been superficially analysed and the business model of these platforms has not yet been studied in detail and depth. The objective of this article is to identify and analyse the business model of the nine Spanish active fact-checking services through a documentary research of public information sources and the information that these services give about themselves. This paper explains their ownership structure and income provenance, from open information sources. The findings are that the fact-checking services that depend on media groups are no strangers to the trend of opacity usual in these groups, but in the case of fact-checking services that are born as initiatives of journalists, the trend towards transparency is, in the majority of cases, clear. However, the information provided by the Spanish fact-checking services is deficient and does not allow us to discover their business models, except in the case of Newtral and, to a certain extent, Maldita

La adaptación de las empresas a la realidad COVID: una revisión sistemática

The sudden emergence of the COVID-19 pandemic has led to profound social and economic changes. Companies have been forced to pivot their business models to ensure their continuity. This study delves into the trends observed in the changes in business models during this crisis. The objective of this research has been to identify the factors behind the initiatives they have taken, as they will presumably be consolidated and will be the basis for disruptions unthinkable before the pandemic. A rapid systematic review has allowed to recover and summarize the results of the most relevant research in this field. Twenty-eight articles have been selected from the main scientific databases, Scopus and Web of Science, using the inclusion decision flowchart proposed by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). The main findings of qualitative analysis that has been carried out highlight the importance of technology, with the generalization of digital marketing and sales channels in companies, teleworking and consumption of technological products such as Artificial Intelligence; the adoption of innovations related to the value proposition, in most cases in the form of new products and services, as a more common form of consumer experimentation; and the generalization of collaborative initiatives among all actors in the business ecosystem.La súbita irrupción de la pandemia COVID-19 ha propiciado profundos cambios sociales y económicos. Las empresas se han visto obligadas a pivotar sus modelos de negocio para asegurar su continuidad. El presente estudio profundiza en las tendencias observadas en los cambios de los modelos de negocio durante esta crisis. El objetivo de esta investigación ha sido identificar los factores que se encuentran detrás de las iniciativas que han adoptado las empresas, pues presumiblemente se consolidarán y serán la base de disrupciones que eran impensables antes de la pandemia. Una rápida revisión sistemática ha permitido recuperar y resumir los resultados de las investigaciones más relevantes en este campo. Se han seleccionado veintiocho artículos de las principales bases de datos científicas, Scopus y Web of Science, utilizando el diagrama de flujo de decisiones de inclusión propuesto por PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis). Los principales hallazgos del análisis cualitativo que se ha realizado destacan la importancia de la tecnología, con la generalización de canales digitales de marketing y ventas en las empresas, el teletrabajo y el consumo de productos tecnológicos como la Inteligencia Artificial; la adopción de innovaciones relacionadas con la propuesta de valor, en la mayoría de las ocasiones en forma de nuevos productos y servicios, como forma más común de experimentación de cara al consumidor; y la generalización de iniciativas de colaboración entre todos los actores del ecosistema empresarial

Salvados: una nueva visión del género reportaje en televisión

En los últimos años, las cadenas generalistas de televisión españolas han apostado por incluir en sus parrillas numerosos programas que tienen como fundamento el género del reportaje, entre los que se encuentran Informe Semanal, Equipo de Investigación… Sin embargo, el programa Salvados, emitido en La Sexta y presentado por Jordi Évole, es el que destaca en los datos de las audiencias y de los seguidores en las redes sociales. En el presente trabajo se analizan las características y estrategias comunicativas de sus reportajes, que han llevado a Salvados a convertirse en un referente de los programas de reportajes informativos. Además, se estudia la evolución que ha experimentado el programa desde sus inicios en 2008 hasta la actualidad
