The influence of social capital on risk-taking propensity. A study on Chinese immigrant entrepreneurs

This paper studies the influence of social capital on immigrant entrepreneurs’ risk-taking propensity. The paper has a particular focus on Chinese immigrants and also explores the effects of the so-called “guanxi”, a specific form of social capital for Chinese communities. The empirical research is based on a survey conducted in 2012 on Chinese immigrant entrepreneurs in Andalusia (Spain). An ordinal logistic regression specification was employed to test the hypotheses. The results show that the Chinese immigrant entrepreneurs with greater structural, relational and cognitive social capital and better “guanxi” have a higher risk-taking propensity in their business activity

On the internationalization of SMEs and its contribution to Spain’s image abroad

Este artículo reivindica el papel de las PYME como actores estratégicos en la conformación de una buena imagen exterior de España. En el actual escenario de globalización, en el que la nacionalidad de las grandes corporaciones tiende a diluirse, las PYME podrían llegar a contribuir más establemente a la marca España por su vinculación más permanente y estrecha al territorio. Igualmente, en algunos contextos, como en el caso de Latinoamérica, las PYME podrían coadyuvar a una imagen más amable de España en el exterior. El trabajo presenta algunos rasgos esenciales del grado y tendencias de internacionalización de la PYME española. Desde esta perspectiva, el artículo analiza los mecanismos y condicionantes que delimitan la contribución potencial que las PYME pueden realizar a la marca España. Asimismo, se señalan algunas ventajas de asociar la imagen exterior de España a las PYME y algunas posibles iniciativas para mejorar la contribución de las PYME internacionalizadas a la marca España.This article vindicates the role of SMEs as strategic actors in shaping a good image of Spain abroad. In the current framework of globalization, the nationality of corporations tends to fade. Hence, SMEs could contribute more stably to improving the nation brand of Spain due to its more permanent and close linkage to the territory. Similarly, in some specific contexts, as in the case of Latin America, SMEs could contribute to a more friendly image of Spain abroad. The paper presents some essential characteristics and trends of the internationalization of Spanish SMEs. From this perspective, the article analyzes the mechanisms and factors which delimit the potential contribution that SMEs can make to the nation brand of Spain. Furthermore, the article points out some advantages of associating the external image of Spain with SMEs and some possible initiatives to enhance the contribution of internationalized SMEs to Spain’s national branding project

The phenomenon of sharenting and its risks in the online environment. Experiences from Czech Republic and Spain

The possibility for parents to share personal and sensitive information about their children, known as sharenting. This phenomenon is becoming more and more common and in recent years is spreading. The objectives of this paper were to analyse the type of content that parents publish about their children and to compare the sharenting behaviour of Czech and Spanish parents. A quantitative methodology was used in a sample of Czech and Spanish parents (N = 1,460). As part of the research, we monitored how many respondents are sharing, in what environment, through what services and what types of their children's material they share, and to whom they make it available. Among the results is that a large majority of parents publish photographs of their children on social networks accessible to their contacts, while not taking into account the privacy of the child. Finally, the main implications are discussed and a series of recommendations are collected for parents in order to avoid risks in the life of the minor

Mexican and Spanish university students’ Internet addiction and academic procrastination: Correlation and potential factors

The 21st-century problem of Internet addiction is increasing globally, but especially among university students. Not surprisingly, then, problematic Internet use is associated with university students’ academic procrastination. Because studies are scarce in Mexico and Spain has one of the highest rates of Internet addiction in Europe, this paper (i) analyzed the presence and degree of Internet addiction among university students in Mexico and Spain, (ii) determined potential sociodemographic factors influencing Internet addiction, and (iii) established the type of correlation between Internet addiction and academic procrastination. The cross-sectional study design used an online questionnaire to measure problematic Internet use and academic procrastination through convenience sampling at one university in Mexico and one in Spain. The questionnaire contained three sections: participants’ sociodemographic data, the Internet Addiction Test, and the Academic Procrastination Scale. The final sample comprised 758 university students, 387 from Mexico, and 371 from Spain, aged from 18 to 35 (M = 20.08, SD = 3.16). Results revealed similar prevalence rates of problematic and daily Internet use for leisure, potentially influencing Internet addiction in all three models (i.e., Mexico, Spain, and Total). Additionally, significant positive correlation was revealed between problematic Internet use and academic procrastination (p < .001). Finally, findings showed relevant data on Internet addiction’s prevalence in Mexican and Spanish university contexts, along with its influential sociodemographic factors.Aznar-DíazI, Romero-Rodríguez J-M, García-González A, Ramírez-Montoya M-S (2020) Mexican and Spanish university students’ Internet addiction and academic procrastination: Correlation and potential factors.

Purification of Starch Granules from Arabidopsis Leaves and Determination of Granule-Bound Starch Synthase Activity

Starch constitutes the most important carbon reserve in plants and is composed of branched amylopectin and linear amylose. The latter is synthesized exclusively by the Granule-Bound Starch Synthase (GBSS, EC 2.4.1.21). Here we report a readily reproducible, specific and highly sensitive protocol, which includes the isolation of intact starch granules from Arabidopsis thaliana leaves and the subsequent determination of GBSS activity. We have applied this method to study GBSS activity in diurnal cycles in vegetative growth and during the photoperiodic transition to flowering in Arabidopsis (Tenorio et al., 2003; Ortiz-Marchena et al., 2014).España,MINECO CSD2007-00057, BIO2008-02292, and BIO2011-28847-C02-00España, Junta de Andalucía P06-CVI-01450 and P08-AGR-0358

Representación del conocimiento experto de un tutor e-learning a través del mapa conceptual: Un modelo de buenas prácticas docentes

El presente proyecto de investigación versa sobre la captura y representación del conocimiento experto a través del mapa conceptual de un tutor e-learning, agente de buenas prácticas docentes. La metodología de trabajo es mixta, combina tanto instrumentos cuantitativos: cuestionario cerrado tipo Likert, como cualitativos: entrevista semiestructurada. El cuestionario fue elaborado ad hoc en base a las funciones y competencias del buen tutor e-learning recogidas por Yot y Marcelo (2013), aplicándose a una muestra de 13 tutores e-learning pertenecientes al departamento de tutorización de una Escuela de Negocios de Granada, donde se imparten enseñanzas de Educación Superior. Tras el análisis de los datos, se determinó a un e-tutor como agente de buenas prácticas en base a las respuestas satisfactorias y los criterios establecidos, al cual posteriormente se le realizó la entrevista para poder realizar una aproximación a su conocimiento experto sobre la tutorización e-learning. Los datos obtenidos del cuestionario se analizaron a través de la hoja de Excel, mientras que los de la entrevista mediante el software cualitativo Atlas.ti. Finalmente fueron representados en dos mapas conceptuales, uno referente a su experiencia docente y otro donde se recogen pautas de actuación sobre buenas prácticas docentes en tutorización e-learning. Además, el mapa de conocimiento generado sirve como modelo para el perfeccionamiento y formación inicial de nuevos formadores.Universidad de Granada. Facultad de Ciencias de la Educación.

Determination of Soluble Sugars in Arabidopsis thaliana Leaves by Anion Exchange Chromatography

Determination of soluble sugars is basic for the study of carbon metabolism in plants. Soluble sugar quantitation can be achieved by enzymatic methods implying different coupled reactions. Here we describe a simple method that allows rapid determination of the most abundant soluble sugars (glucose, fructose and sucrose) in Arabidopsis leaves by anion exchange chromatography. We have applied this method to study the levels of soluble sugars during the photoperiodic transition to flowering (Ortiz-Marchena et al., 2014).España, MINECO projects CSD2007-00057, BIO2008-02292, and BIO2011-28847-C02-00España, Junta de Andalucía P06-CVI-01450 and P08-AGR-0358
