Turning teachers into entrepreneurship role models: development of a measurement scale of useful characteristics

The circumstances under which students consider their teachers of entrepreneurship as role models have not received in-depth exploration in the literature. This paper focuses on determining the main personal, professional and pedagogical characteristics that would turn teachers of entrepreneurship into role models and thereby improve the entrepreneurial intentions of students. A three-step empirical research process combining documentary, qualitative and quantitative methods is developed in order to propose and test a measurement scale of teacher characteristics that is reliable, valid and useful for causal modelling. A total of 26 characteristics are identified and classified into personal, professional and pedagogical categories

Metaverse Fashion Week de Decentraland. La sublimación de la moda en metaversos

La moda es un sector clave del tejido económico y cultural. El Covid-19 sirvió de estímulo para la aparición de vanguardistas soluciones tecnológicas. En este contexto, cobran visibilidad los mundos virtuales, entornos digitales replican el ámbito real. Se fija por objeto demostrar la viabilidad y recepción de estos espacios como formas de comunicar y hacer moda entre personas vinculadas a dicho sector. El escalafón final se halla en el abstracto concepto del metaverso, lugares donde algunos ven el futuro de la moda e Internet. Se realiza un estudio de caso apoyado en un cuestionario Likert de la Metaverse Fashion Week (Decentraland), evento pionero y paradigmático donde diversas firmas se reúnen para superar barreras espaciales y abordar una dimensión que implica la aparición de un mercado basado en lo virtual. Los resultados apuntan a que dichas narrativas han llegado a un punto suficiente de madurez y que su acogida será favorable entre el público especializado a medio plazo

Characterization of goat colostrum oligosaccharides by nano-liquid chromatography on chip quadrupole time-of-flight mass spectrometry and hydrophilic interaction liquid chromatography-quadrupole mass spectrometry

A detailed qualitative and quantitative characterization of goat colostrum oligosaccharides (GCO) has been carried out for the first time. Defatted and deproteinized colostrum samples, previously treated by size exclusion chromatography (SEC) to remove lactose, were analyzed by nanoflow liquid chromatography–quadrupole-time of flight mass spectrometry (Nano-LC-Chip–Q-TOF MS). Up to 78 oligosaccharides containing hexose, hexosamine, fucose, N-acetylneuraminic acid or Nglycolylneuraminic acid monomeric units were identified in the samples, some of them detected for the first time in goat colostra. As a second step, a hydrophilic interaction liquid chromatography coupled to mass spectrometry (HILIC-MS) methodology was developed for the separation and quantitation of the main GCO, both acidic and neutral carbohydrates. Among other experimental chromatographic conditions, mobile phase additives and column temperature were evaluated in terms of retention time, resolution, peak width and symmetry of target carbohydrates. Narrow peaks (wh: 0.2–0.6 min) and good symmetry (As: 0.8–1.4) were obtained for GCO using an acetonitrile:water gradient with 0.1% ammonium hydroxide at 40 ◦C. These conditions were selected to quantify the main oligosaccharides in goat colostrum samples. Values ranging from 140 to 315 mg L−1 for neutral oligosaccharides and from 83 to 251 mg L−1 for acidic oligosaccharides were found. The combination of both techniques resulted to be useful to achieve a comprehensive characterization of GCO.This work has been funded by Junta de Andalucía (project AGR2011-7626), CSIC (project i-link0827), Comunidad Autónoma de Madrid (Spain) and European funding from FEDER program (AVANSECAL-CM S2013/ABI-3028) and Fundación Ramón Areces.

Explaining residents' attitudes towards tourism and tourists: A new approach based on brand theory

ABSTRACT: Considering host communities as brands in the eyes of local people, our study examines how resident attitudes towards tourism and tourists are influenced by two brand factors: (a) equity perceptions related to their communities (i.e., brand equity) and (b) identification with their communities (i.e., brand identification). Our empirical results indicate that resident attitudes towards tourism are positively influenced by equity perceptions and identification, whereas attitudes towards tourists are positively influenced by attitudes towards tourism and identification with the community. These findings represent a step forward in better understanding how both types of resident attitudes are influenced by nontourism-related factors

Ciberacoso y ansiedad social en adolescentes: una revisión sistemática

El ciberbullying ha suscitado el interés de los investigadores en el campo de la psicología. Una de las variables que se ha estudiado en los últimos años en relación con el ciberbullying es la ansiedad social. Sin embargo, no se ha realizado una evaluación global y específica de los resultados en estas dos grandes áreas. El objetivo de este estudio es sintetizar los resultados de los estudios que analizan la asociación entre la ansiedad social y el ciberbullying. Se realizó una revisión sistemática de estudios publicados en Web of Science y PsycINFO. Los criterios de inclusión de los estu- dios fueron: (1) analizar la relación entre la ansiedad social y las experiencias de ciberbullying; (2) centrados en niños y adolescentes entre 9 a 19 años; (3) publicados entre 1996 a 2016; y (4) disponibles en inglés. De las 287 publicaciones encontradas inicialmente, 13 estudios cumplieron con los criterios de inclusión. En los estudios transversales se encontró que existe mayoritariamente una relación positiva entre AS y CB. Dos estu- dios concluyeron que la ansiedad social predice un aumento de las experiencias de cibervictimización. Cuatro estudios no encontraron la ansiedad social como consecuencia psicológica de las experiencias de cibervictimización; mientras que uno sí encontró relación. El ciberacoso generalmente no se relacionó con mayores niveles de ansiedad social. La mayoría de estudios indicaron que la ansiedad social es un factor de riesgo para la cibervictimización, y en menor medida una consecuencia de ésta. Investigaciones futuras con diseños longitudinales son necesarias para analizar las asociaciones bidireccionales de la ansiedad social y el ciberbullying

The importance of entrepreneurship education and its terminology

The analysis of the specialized literature on entrepreneurship education shows the existing doubts about its validity and the difficulty of comparing and generalizing the results obtained by previous research on this education, as there are many difficulties in its definition and terminology. Therefore, the objective of this work is to establish and delimit a definition that integrates the different perspectives existing in the previous literature and thus, to be achieved a unified language that contributes to define training programs that achieve the desire objectives, increase the entrepreneurial intentions and improve entrepreneurial skill

La relevancia de las partes interesadas, las noticias positivas de RSC y el valor de mercado de los bancos

ABSTRACT. This research explores the effects that media coverage of corporate social responsibility (CSR) news related to investor, customer, employee and community issues has on the market value of Spanish banks, measured as the impact generated in abnormal returns for these companies. We use an event study with a sample of 190 positive CSR articles published online between 2015 and 2018 in the most important Spanish business newspaper according to its diffusion rate. The findings demonstrate that positive CSR news related to investor, customer, employee and community issues generates positive abnormal returns for listed banks. In the [−1,+1] window, positive investor news has notably larger effects on the abnormal returns for these companies than positive news related to customer, employee and community issues, which have similar effects.RESUMEN. Esta investigación explora los efectos que la coberturamediática de las noticias de responsabilidad social corporativa (RSC), relacionadas con temáticas de inversores, clientes, empleados y sociedad, tiene sobre el valor de mercado de los bancos españoles, medido este indicador como el impacto generado en los retornos anormales de estas empresas en el mercado de valores. Para cumplir con este objetivo, utilizamos un estudio de eventos con una muestra de 190 artículos de RSC publicados entre 2015 y 2018 en la versión online del periódico económico español más importante según su tasa de difusión. Los resultados demuestran que las noticias de RSC relacionadas con temáticas de inversores, clientes, empleados y sociedad generan retornos anormales positivos para los bancos que cotizan en bolsa. En la ventana [–1,+1], las noticias positivas para los inversores tienen efectos notablemente mayores sobre los retornos anormales de estas empresas que las noticias positivas relacionadas con temáticas de clientes, empleados y sociedad, que tienen efectos similares

Positioning System for Fishing Fleets' Tracking and Assistance

The safety of people working at sea is a subject on which many studies have been carried out. One of the current improvements that has been implemented is the possibility of assigning medical support assistance vessels during specific periods of time, whilst undergoing certain activities or peak seasons in the industry such as fishing seasons. This article proposes an aid system that will support decision making when determining the positioning of such vessels at configurable time intervals, thus shortening the emergency response time. Real data from the vessels, such as coordinates, number of crew, type of fishing gear, etc., are used to carry this out. With the scope of testing the system out, real data from the Spanish fishing fleet in the Bay of Biscay and the medical support assistance vessels available to the Spanish State have been used throughout different seasons. The results obtained convey the “standby” positions for these vessels. The following study of this comparative positioning enables us to calculate the differences between the coordinates calculated by the system and the real positions specified throughout the fishing season. The study also reviews the possibility of improving the emergency response time that would be gained, by increasing the number of medical support assistance vessels for the same area, during the same period
