Las Tecnologías de la Información y Comunicación se han desarrollado con rapidez integrándose en la vida cotidiana de los adolescentes y los jóvenes. Por ello, esta investigación con diseño no-experimental y transversal analizó las diferencias por sexo en el uso problemático del internet, el cyberbullying y la ciber-violencia de pareja; así como la posible relación entre las variables mencionadas. La muestra fue conformada por 456 estudiantes, procedentes de dos universidades mexicanas, con edades entre 17 y 30 años (M = 19,86; DT = 2,12). Los resultados mostraron pocas diferencias entre hombres y mujeres; asimismo se presentaron correlaciones bajas positivas entre la mayoría de los indicadores de uso problemático de internet con ciberbullying; el uso problemático de internet y ciber-violencia de pareja; y entre ciberbullying y ciber-violencia de pareja. Se concluyó que las conductas violentas de jóvenes mediante nuevas tecnologías parecen generalizarse a las relaciones entre pares y de pareja. Se discuten los resultados destacando la necesidad de más estudios sobre estos fenómenos cada vez más presentes en jóvenes.
Rosehips (Rosa spp., Rosaceae) are wild rose bushes with more than 100 species. Its fruits vary in colour and size, depending on the species, and are recognised for their nutritional characteristics. Ten samples of Rosa canina L. and Rosa rubiginosa L. fruits were collected at different geographical points from Southern Chile. Nutrients such as crude protein and minerals and functional properties such as phenolic compounds, ascorbic acid, and also antioxidant activities were evaluated by HPLC-DAD-ESI-MS/MS. The results revealed a high content of bioactive compounds, primarily ascorbic acid (6.0 to 8.2 mg g−1 fresh weight (FW)), flavonols (427.9 ± 0.4 μg g−1 FW) and antioxidant activity. We established a relationship between the antioxidant activity using Trolox equivalent antioxidant capacity (TEAC), cupric reducing antioxidant capacity (CUPRAC) and 2,2-diphenyl radical (DPPH) methods and the concentration of uncoloured compounds, such as flavonols and catechin. This antioxidant activity was primarily associated with the samples from Gorbea, Lonquimay, Loncoche, and Villarrica localities, and all of them were of the species Rosa rubiginosa L. The results here obtained represent novel information of rosehip fruits. In this sense, the reported information about compounds and antioxidant activities in rosehip fruits allowed us to continue new lines of research in relation to the potential formulation of new functional foods and also in the treatment and/or prevention of some diseases.
Objective: The objective of this study was to identify pedestrian risk behaviors that result in traffic accidents and characterization of the accidents experienced by participants in this study to provide information for the generation of integral preventive strategies. Methods: The study was correlational, descriptive, and transversal and followed a quantitative approach divided into 2 stages. In the first stage, an observational study was performed to identify the manifested risk behaviors of pedestrians, which served as a basis for the construction and design of a questionnaire. In the second stage, the questionnaire was applied to a group of 1,536 participants. Pearson's correlation coefficient was applied to establish associations between gender and age with respect to risk behaviors. Results: The 3 behaviors that participants reported performing always or very often include using electronic gadgets (except mobile phones), not using a pedestrian crosswalk, and using a mobile phone. In addition, 18.5% were involved in at least one road accident as a pedestrian in the last 5 years. Of the total number of registered accidents, 21% resulted in pedestrian injuries, 48.3% of which were serious. These were due to external causes not related to human factors or unidentified (58.5%) and behavior factors as a whole (41.4%, 31.5% of which were caused by pedestrians). Pearson's correlation coefficient showed evidence of a correlation between age and risk behaviors. Conclusions: All subjects in this study performed several risky actions as pedestrians, at least occasionally, and at least one fifth had been involved in a road accident as a pedestrian. It is known that the surroundings can positively or negatively influence individuals' behaviors; therefore, once prevention measures are identified, it is possible to influence risk behaviors. Therefore, road safety education and the physical environment must be considered together, and efforts focused on optimum infrastructure also need to consider road safety education.
El estudio tiene como objetivo conocer la probabilidad de presentar adicción y los factores determinantes sobre el uso problemático del internet en estudiantes universitarios en la ciudad de H. Matamoros, Tamaulipas. Metodología: La población fue de 1,125 estudiantes y una muestra de 323, en una universidad pública, el instrumento utilizado fue el “Cuestionario de Uso Problemático de Internet” (CUPI) con un Alfa de Cronbach de 0.966, el diseño de estudio fue descriptivo, transversal. Resultados: se encontró que el factor de determinante “Anticipación” fue el que presento una mayor probabilidad de presentarse, y los de menor fueron “Pérdida de Control” y “Reconocimiento de Falta de Control.”
