Asegúrate: an intervention program against cyberbullying based on teachers' commitment and on design of its instructional materials

This article presents the impact on cyberbullying of the Asegúrate program. This educational program is based on the theory of normative social behavior, self-regulation skills,and the beliefs held by adolescents and consists in a whole package of strategies and resources to help teachers to include in the ordinary curricula. The evaluation of Asegúrate was carried out with a sample of 4779 students (48.9% girls) in 5th and 6th grade in primary education and compulsory secondary education (M = 12.76; SD = 1.67) through a quasi-experimental methodology, with two measures over time. The instrument used was the European Cyberbullying Intervention Project Questionnaire. The results show that the involvement in cyberbullying as cyber-victim,cyber-aggressor, and cyber-bully-victim increase without intervention, whereas it diminishes when intervention is carried out by the teachers who have received specific training and have used the didactic Asegúrate package. Additionally, the impact of the intervention on the different types of behaviors was analyzed, and the results show that Asegúrate is more effective with some forms than with others. Consequently, the Asegúrate program is effective for decreasing the prevalence of cyberbullying, but some modifications need to be made to impact on all the different forms it can take.Gobierno de España PSI2017-86723-RGobierno de España PSI2016-74871-

Commitment in University Students: Generator of Successful Professionals

The University has historically been regarded as the harbinger of values, human rights, and other noble pursuits. It is within this atmosphere that personal development, mutual respect, and collaboration are expected to flourish through commitment to work and study. Yet in order for meaningful and sustainable social, economic, and political changes to take root, the author opines that certain adjustments to the overall social fabric are occasionally required and can only be achieved through unyielding commitment — an essential value transmitted from person to person through both individual and collective reflection

Physical Treatments and Propolis Extract to Enhance Quality Attributes of Fresh-Cut Mixed Vegetables

The impact of individual and combined application of propolis extract (PE) plus ultrasound (ULT) or thermal treatment (TT) on the microbiological, nutritional, physicochemical and sensory quality of fresh-cut mixed vegetables for soup (celery, leek and butternut squash) stored at 5C was studied. The use of PE slightly reduced microbial growth, inhibited the activity of browning related enzymes and improved quality attributes during refrigerated storage. Moreover, PE was effective to reduce ascorbic acid losses in the product maintaining its nutritional quality. TT greatly lowered the initial microbial load (1.7–2.2 log units) and also reduced microbial growth on mixed vegetables extending its microbiological shelf-life to 5 days. Furthermore, TT inactivated browning enzymes improving visual quality; however, ascorbic acid degradation adversely affected nutritional quality. Meanwhile, ULT caused a significant microbial inactivation, reduced browning enzyme activity and also the inhibitory effect on polyphenoloxidase enzyme was enhanced by combining ULT with PE. Practical Applications: The use of natural agents, as propolis extract, along with physical treatments to preserve the quality of fresh-cut mixed vegetables for soup might be an interesting option to address the concerns of the consumer about the use of synthetic chemical antimicrobials potentially harmful for health.Fil: Alvarez, María Victoria.

Determinantes del tipo impositivo efectivo en el sector turístico: un modelo dinámico con datos de panel

This paper presents a dynamic model of the Effective Tax Rate (ETR) in the tourism sector. A dynamic model where the lagged endogenous variable ETR has been included as a regressor to identify the dynamic structure of the variable due to the existence of temporal adjustments between the short and long run in ETR payments has been estimated. The empirical analysis based on a panel data set over the 2008-2013 period explores the determinants of the ETR variable by using a Generalised Method of Moments (GMM) estimator controlling for heterogeneity in the tourism sector. The Arellano-Bond system GMM estimator has been used to estimate the model. The study seeks to shed light on the determinants of tax burden in the tourism sector covering the lack of studies on this topic. The findings obtained suggest that the ETR borne is determined by size, financing structure and type of entity. We deem the finding of the existence of non-linear relationships between ETR and size and financing structure relevant.Este artículo presenta un modelo dinámico para el Tipo Impositivo Efectivo (TIE) en el sector turístico. Este modelo dinámico ha sido estimado usando la variable endógena retardada TIE como regresor para identificar la estructura dinámica de dicha variable, debido a la existencia de ajustes entre el corto y largo plazo en los pagos del TIE. El análisis empírico basado en datos de panel en el periodo 2008-2013 explora los determinantes de la variable TIE utilizándose el estimador del Método Generalizado de Momentos (GMM) controlando la heterogeneidad en el sector turístico. El estimador de Arellano-Bond ha sido utilizado para estimar el modelo. Este estudio busca arrojar luz sobre los determinantes de las cargas impositivas en el sector turístico debido a la escasez de estudios en esta materia. Los resultados obtenidos sugieren que el TIE se encuentra determinado por el tamaño, la estructura financiera y el tipo de empresa. Igualmente consideramos relevante el hallazgo de relaciones no lineales entre el TIE y el tamaño y la estructura de financiación

El programa de ayuda entre iguales en el contexto del proyecto Sevilla Antiviolencia Escolar

El modelo de intervención que se propone en el Proyecto Sevilla Anti-Vio- lencia Escolar está orientado a la prevención de la violencia escolar mediante la aten- ción a la educación para la convivencia (Ortega, 1997). Sin embargo, no ha dejado de pensar en la atención a aquellos chicos/as que, por una u otra razón, están ya en una situación de riesgo y pueden verse implicados en problemas de malas relaciones, aislamiento o exclusión social por parte de sus compañeros/as. De esta forma, dentro del proyecto SAVE, se diseñaron tres líneas de actuación para trabajar con los escolares en riesgo: los círculos de calidad, la mediación en conflictos y los programas de ayuda entre iguales; éstos últimos inspirados en el modelo propuesto por Cowie y Sharp (1996). El artículo que se presenta es un informe del desarrollo de este último progra- ma en dos centros educativos de Sevilla, sus ventajas y la necesidad de resolver ciertas dificultades para posteriores intervenciones
