Parenting practices as risk or preventive factors for adolescent involvement in cyberbullying: Contribution of children and parent gender
Literature points out the role of parenting on adolescent cyberbullying involvement. However, it is necessary to clarify how gender affects this relationship. The aim of this study has been to examine the relation between the adolescents’ perception about parenting practices, and their involvement in cyberbullying, bearing in mind both girls’ and boys’ gender and progenitors’ gender. The sample comprised 2060 Spanish secondary school students (47.9% girls; Mage = 14.34). Two-way ANOVA and binary logistic regression analyses were carried out. An effect of the interaction between sex and cyberbullying roles in maternal affection and communication, inductive discipline, and psychological control, as well as paternal promotion of autonomy and psychological control, was found. In general, it can be observed that the more negative results were found in cyber-aggressors, especially when this role is assumed by girls. The results of logistic regression analysis suggest that parenting practices explain better cyberbullying involvement in girls compared to boys, finding some important differences between both sexes regarding protective and risk factors. These findings highlight the importance of parenting practices to explain cyberbullying involvement, which supports the necessity of including family among the addresses of intervention programs.Gobierno de España PSI2016-74871-RGobierno de España PSI2015-64114-REuropean Research Council H2020 grant number 75517
Escritura y escrutinio paranoico en La invención de Morel de Adolfo Bioy Casares
En La invención de Morel (1940), Adolfo Bioy Casares presenta un personaje anónimo que, a lo largo del texto, se encargará de describir al detalle las condiciones de una isla deshabitada (en apariencia), al mismo tiempo que trata de asegurar su supervivencia. Sin embargo, por medio de este narrador no confiable, el autor argentino también toma en consideración los principios de géneros populares (la ciencia ficción, el relato policial, etc.) para conformar otra especie de forma literaria de base especulativa. Echando mano al recurso de la isla, del objeto del deseo inalcanzable (que se contempla y se persigue), del enigma, el doble y los fantasmas, esta novela contiene una serie de entrampamientos de los que tanto el lector como el mismo protagonista a cargo del diario tendrán que salir (cada cual a su manera). A fin de cuentas, se pretende explorar las irregularidades insulares en relación con el tiempo, la muerte, la violencia, el simulacro y el disfraz. Estos elementos, a su vez, desencadenan otras subestructuras que van de la definición de lugar y la superposición de utopía y distopía, la visión sentimental y la construcción y perdurabilidad de una memoria externa
Projecting the impacts of climate change on wheat yields in the UK and Germany and assessing modeling uncertainties
Climate change and variability are projected to negatively affect wheat production in Europe. The impacts of climate change are typically projected using global and regional climate models (GCMs and RCMs) and impact assessment tools such as crop models. However, this impact simulation chain can propagate uncertainty, as errors are introduced by GCMs, RCMs, and crop models. There are also many intermediate steps and decisions in the impact simulation process that are influenced by the different communities of practice that utilize climate and crop models. These differences in methods and approaches can also influence the range of future yield projections. Yield projections are thus considered inherently uncertain because of this cascade of uncertainty.
This interdisciplinary study projects the impacts of climate change on wheat yields in the UK and Germany, two key wheat-growing countries. Added value is found when using RCMs for downscaling temperature and precipitation simulations for the impact assessment. However, these GCM-RCM simulations are shown to have significant errors relative to observations, necessitating a bias correction (BC) step. Different BC methods are shown to be effective in improving simulations. Two BC calibration approaches, one that corrects RCM-only error and the other GCM-RCM error, are used to examine how different GCM-RCM combinations can affect projected changes in climate. Future climate projections are used in a multi-method crop modeling approach, and the uncertainty in the resulting yield projections is analyzed. Key findings are that wheat yields in the UK and Germany will be affected by changes in temperature and precipitation. However, these impacts are shown to be region-dependent and vary based on the crop modeling method, making the choice of crop modeling method a major contributor to uncertainty
Aggressive Driving Behaviours in Cannabis Users. The Influence of Consumer Characteristics
This study analysed dangerous driving behaviours in twenty young occasional cannabis
users through objective and self-reported data, studying the relationship between the two aspects.
Visual function was assessed in a baseline session and after smoking cannabis, as well as speed-related
behaviour in a driving simulator. The participants responded to questionnaires on sociodemographic
factors, their consumption profile, and the incidence of dangerous behaviours (Dula Dangerous
Driving Index; DDDI). After cannabis use, the results revealed a significant deterioration in visual
function. In terms of speed management, they showed significantly greater acceleration force in
the two different sections of the route, and they drove significantly faster. Our correlations indicate
that males and heavier users display more risky speed management. Likewise, the heavier cannabis
users admitted to increased dangerous driving behaviour, and an accident in the preceding year was
associated with a trend towards aggressive driving behaviour according to the DDDI questionnaire.
The findings of this study suggest that cannabis users adopt dangerous behaviours when driving,
despite the effect this drug has on certain important functions, such as vision. The results suggest a
need for awareness-raising and information campaigns
Relación del Control Glucémico, Función Cognitiva y las Funciones Ejecutivas en el Adulto Mayor con Diabetes Tipo 2: Revisión Sistemática
Aim: To review the available evidence to show the relationship between glycemic control, cognitive function and executive functions in the AM with T2D.Methods: The literature search was conducted in English and Spanish, in 14 databases, Open Access, and the Google search engine. Based on the model proposed by Cooper (2007), for the synthesis of the literature. The studies were assessed for validity through CASPe guide for case-control studies.Results: We analyzed correlation 11estudies 100% of the studies showed glycemic control relationship to cognitive impairment and executive function in AM with DT2. Studies agree that the AM with DT2 have cognitive impairment, compared with AM without DT2, therefore there is a deficit in the AM to perform executive functions.Conclusions: Based on the available evidence there is a significant relationship in glycemic control and cognitive impairment in the AM with DT2, also a lower performance in functional mobility and verbal fluency.Objetivo: Revisar la evidencia disponible que demuestre la relación que existe entre el control glucémico, función cognitiva y las funciones ejecutivas en el AM con DT2. Métodos: La búsqueda de la literatura se realizó en idioma inglés y español, en 14 bases de datos, Open acces, y en el buscador Google. En base al modelo propuesto por Cooper (2007), para la síntesis de la literatura. Los estudios fueron evaluados para su validez, a través de la guía CASPe para estudios de casos y controles. Resultados: Se analizaron 11estudios de correlación, el 100% de los estudios mostró relación del control glucémico con el deterioro cognitivo y la función ejecutiva en AM con DT2. Los estudios concuerdan que los AM con DT2 presentan deterioro cognitivo, comparado con los AM sin DT2, por lo tanto existe déficit en el AM al realizar las funciones ejecutivas.Conclusiones: Según la evidencia disponible existe una relación significativa en el control glucémico y el deterioro cognitivo en el AM con DT2, así mismo un menor desempeño en la movilidad funcional y la fluidez verbal
Diminutive and Nominal Aspect in Spanish
Indexación: Revista UNABEn este trabajo se aborda el tema del aspecto nominal y cómo
este influye en la formación del diminutivo de base nominal en
español. Con un acercamiento funcional a los datos, el análisis
aporta evidencia de que el español dispone de dos recursos para
diminutivizar nombres: el morfológico, mediante el uso del sufijo
-it, que puede ser aplicado a cualquier clase de nombre y puede ser usado para disminuir de manera tanto objetiva como
subjetiva a los nombres contables concretos, mientras que el
segundo recurso, que llamaremos morfosintáctico y que consiste
en añadir el mismo sufijo al núcleo nominal de una frase
delimitadora, propio de los nombres de masa, es más flexible en
cuanto a los efectos semánticos que puede producir.This paper addresses the issue of diminutives in Spanish and how
the nominal aspect influences their formation as well as the values
they can assume. The analysis provides evidence that Spanish
has two resources to create a diminutive from a noun; first, the
suffix -it, called morphological, which can be applied to any kind
of name and can be used to diminish concrete countable nouns
both objectively and subjectively; while the second, the morphosyntactic
resource, which adds the same suffix to the nominal
head of a bounded phrase —a characteristic of mass nouns—,
is more flexible concerning the semantic effects it can produce.http://revistahumanidades.unab.cl/wp-content/uploads/2013/07/A7.-CASTILLO-ORTIZ.pd
Percepciones del alumnado universitario sobre conciliación laboral y familiar
La finalidad del estudio que presentamos es conocer cuáles son las percepciones del alumnado universitario de la Facultad de Ciencias de la Educación en torno a la conciliación entre el mundo laboral y el mundo familiar. La conciliación es objeto de múltiples estudios desde una perspectiva reactiva. En este sentido, esta investigación asume un enfoque proactivo para anticiparse a las situaciones futuras de conciliación que puede experimentar el alumnado.
La investigación se ha llevado a cabo en una muestra de 51 estudiantes de la Facultad de Ciencias de la Educación (Universidad de Sevilla). La metodología empleada es la propia de un estudio descriptivo, transversal, de carácter exploratorio centrada en el cuestionario como estrategia de recogida de información. Los resultados obtenidos apuntan a que la conciliación es un aspecto muy valorado por los/as estudiantes y tienen un conocimiento parcial de medidas formales de conciliación, estrategias,…
No obstante, como veremos, hay algunos factores que indican la carencia de modelos de referencia entre el alumnado en cuanto a conciliación, un escaso desarrollo de habilidades personales para el manejo de situaciones en la que compatibilizar ambos dominios, así como preferencias en cuanto a estrategias y modos de afrontamiento que dificultan la conciliación
