Ciberviolencia en las relaciones de pareja: una revisión sobre su metodología de investigación
Authors: Rodríguez Domínguez Carmen , Pérez-Moreno Pedro J. , Durán Mercedes 
Published: April 2020

En los últimos años ha aumentado el interés por el estudio de la ciberviolencia en la pareja, sin embargo es necesario examinar la metodología de investigación que sustenta las evidencias obtenidas hasta el momento. Este artículo presenta una revisión sistemática de la literatura científica que analiza 30 instrumentos de medida de ciberviolencia en la pareja de adolescentes y jóvenes adultos utilizados a lo largo de estos años. Los principales resultados muestran una elevada pluralidad metodológica, conceptual y terminológica, observándose un reducido número de instrumentos con suficientes garantías psicométricas. Predominan los trabajos de procedencia estadounidense y, entre los instrumentos aplicados en muestras españolas, destaca una infrarrepresentación de indicadores de ciberviolencia de tipo sexual, lo que limita la comprensión de esta problemática. Esta investigación aporta información sobre el estado actual en el estudio de la ciberviolencia en la pareja y pone de relieve deficiencias metodológicas en la construcción del conocimiento en este campo de estudio. Este trabajo permite una mejor comprensión de la disparidad de resultados señalada por investigaciones previas, especialmente referidas a prevalencia, frecuencia y diferencias de género en este tipo de comportamientos violentos, además de sentar las bases para abordar el fenómeno desde el rigor científico.
The interest for the study of the cyber dating abuse has increased in the last years; however, it is necessary to examine the research methodology that supports the evidence obtained so far. This paper presents a systematic review of the scientific literature that analyzes 30 measuring instruments of cyber dating abuse in adolescent and young adults used along these years. The main results show a methodological, conceptual and terminological plurality, observing a small number of instruments with sufficient psychometric guarantees. The instruments come mostly from the United States, and of the instruments applied to Spanish samples, few include indicators of sexual cyber dating abuse, which limits the understanding of this problem. This research provides information on the current status of the study of cyber dating abuse and highlights methodological shortcomings in the construction of knowledge in this field of study. This study allows a better understanding of the disparity of results indicated by previous research, especially referring to prevalence, frequency and gender differences in this type of violent behavior, as well as laying the foundations for addressing the phenomenon from scientific rigor.

La calidad del aprendizaje en la Educación Superior depende, especialmente, de las habilidades de los estudiantes para regular su cognición. Esta regulación requiere habilidades cognitivas y metacognitivas, así como dimensiones motivacionales. Dada su relevancia en el rendimiento académico y el desarrollo de habilidades para el aprendizaje a lo largo de la vida, es importante aumentar la investigación en el campo. Este estudio pretende adaptar y validar una versión abreviada da dimensión Regulación de la Cognición del Metacognitive Awareness Inventory para estudiantes universitarios portugueses de primer año. Se empleó una muestra de 360 estudiantes y se identificó una estructura tridimensional (Planificación, 4 ítems; Estrategias, 7 ítems; y Monitoreo y evaluación, 7 ítems) con un factor de segundo orden (Regulación de la cognición). Los valores de consistencia interna de la escala reducida son aceptables para una escala de autoinforme y las correlaciones con el logro académico al final del primer año de la universidad garantizan su validez predictiva. Esta versión abreviada para medir la regulación de la cognición puede usarse en investigación junto con otros instrumentos en estudios más amplios y puede funcionar como una herramienta de diagnóstico para ayudar a los estudiantes en los desafíos de aprendizaje de la enseñanza superior.
The quality of learning in Higher Education is particularly dependent on students' skills in regulating their cognition. This regulation requires cognitive and metacognitive skills as well as motivational dimensions. Due to its relevance in explaining students' academic achievement and developing lifelong learning skills, it´s important to increase research in the area. This study aims to adapt and validate a short version of the Regulation of Cognition of Metacognitive Awareness Inventory to first-year Portuguese university students. A sample of 360 students was considered and was identified a three-dimensional structure (Planning, 4 items; Strategies, 7 items; and Monitoring and evaluation, 7 items) with a second-order factor (Regulation of Cognition). The internal consistency values of the reduced scale are within the acceptable parameters for a self-report scale and the correlations with academic achievement at the end of the first year of the university guarantee the predictive validity of the scale. This short version of regulation of cognition measure allows its use in research with other instruments in larger studies and can function as a diagnostic / screening tool to help students in higher education learning challenges.

Published: April 2020

El sexting es un fenómeno que consiste en el envío y la recepción de fotos, videos y/o mensajes de texto de naturaleza sexual a través de smartphones. Como en todos los demás países desarrollados, se está convirtiendo en una práctica cada vez más popular entre los adolescentes de España. Al tratarse de un fenómeno muy reciente todavía no existen muchos trabajos que hayan estudiado con profundidad su entidad y sus factores implicados. Por tanto, los dos objetivos de este estudio fueron determinar la prevalencia y analizar las variables explicativas del inicio y del mantenimiento de las conductas de sexting. La muestra estuvo formada por 784 adolescentes españoles (52% chicos y 48% chicas) con edades comprendidas entre los 12 y los 18 años (M = 14.44; DT = 1.61). Los resultados indican que el 24.4% ha practicado sexting en alguna ocasión, realizando esta conducta con una media de 2.32 personas (DT = 2.70). El análisis de regresión reveló que las actitudes positivas hacia el sexting, el nivel de impulsividad, la edad, ser hombre y el mantener una relación de pareja son variables que predicen la práctica del sexting. Estos resultados son muy importantes en la elaboración e implementación de estrategias preventivas que enfaticen el uso responsable de las TICS y las redes sociales.
Sexting is a recent phenomenon in which people send and receive photos, videos and/or text messages of sexual nature via smartphones or similar devices. Similar to other developed countries, it is becoming an increasingly popular practice among teenagers in Spain. Provided it has appeared very recently, scarce research has focused on examining in-depth factors involved in its initiation and maintenance. Therefore, the two main aims of this study were to determine its prevalence and to analyse the explanatory variables of the sexting behaviours. The sample consisted of 784 Spanish adolescents (52% boys and 48% girls) between 12 and 18 years of age (M = 14.44; SD = 1.61). The results showed that 24.4% have practised sexting at some time, with an average of 2.32 people (SD = 2.70). The regression analysis revealed that positive attitudes towards sexting, level of impulsivity, age, being male and having a partner are variables that predict engagement in sexting. These results are very important for designing and implementing preventive strategies that emphasise the responsible use of ICTs and social networks.

El objetivo de este trabajo es evaluar empíricamente la eficacia de un programa de intervención con mujeres víctimas de violencia de género. El programa en conjunto se enmarca dentro de las Terapias Contextuales, específicamente se ha utilizado la Psicoterapia Analítica Funcional, combinada con la Terapia de Aceptación y Compromiso y la Activación Conductual. Se ha llevado a cabo en formato grupal, durante 11 sesiones de 2 horas cada una. Participaron un total de 21 mujeres (de una media de edad de 45 años), que habían sufrido violencia física y/o abuso emocional por parte de sus parejas, en diferente grado e intensidad, y en diferentes momentos en sus vidas. Se ha utilizado un diseño intragrupo con medidas pre-post. Se realizaron tres grupos de tratamiento en diferentes ciudades con 6 a 8 mujeres cada uno. Para medir la intervención se ha aplicado el cuestionario Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM). Los resultados han mostrado una disminución estadísticamente significativa en la severidad del malestar, han disminuido los indicadores de riesgo de suicidio, y han mejorado las conductas problemáticas dentro y fuera de las sesiones, además de incrementarse la apertura hacia los demás. Se discute la utilidad de las terapias contextuales para mejorar la calidad de vida de mujeres maltratadas, y su utilidad de aplicación en grupos en las instituciones públicas.
The goal of this study is to empirically evaluate the efficacy of an intervention program with women victims of gender violence. Specifically, Functional Analytical Psychotherapy has been used, combined with Acceptance and Commitment Therapy, and Behavioral Activation. It has been carried out in group format, during 11 sessions of 2 hours each. A total of 21 women participated (an average of 45 years-old), who had suffered physical violence and/or emotional abuse by their partners, with different degrees and intensity, and at different moments of their lives. An intra-group design with pre-post measures was used. Three treatment groups were carried out in different cities with 6 to 8 women each one. To measure the intervention, the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) questionnaire was applied. The results has shown a statistically significant decrease in the severity of discomfort, decreased suicide risk indicators, improved problem behavior inside and outside sessions, and increased openness to others. The usefulness of contextual therapies to improve the quality of life of battered women and their usefulness for application in groups in public institutions are discussed.
Identité professionnelle et agressions dans les métiers spécialisés de la construction et du secteur manufacturier au Québec
Authors: Cloutier Geneviève , Marchand Alain 
Published: April 2020

Cette étude vise à mieux comprendre le lien entre identité professionnelle et agressions fondées sur le sexe et le genre dans les métiers spécialisés de la construction et du secteur manufacturier au Québec. Une limite importante dans la littérature s’avère être l’absence d’étude portant sur l’identité professionnelle et sa fragilisation. L’identité professionnelle englobe l’ensemble des pratiques et des coutumes qui procure une reconnaissance aux travailleurs dans l’exécution de leurs tâches, en plus d’une affirmation d’eux-mêmes au travail (Ashforth et Mael, 1989).
Des questionnaires ont été distribués dans sept chantiers de construction et dans quatre établissements manufacturiers, pour un total de 282 répondants. Les résultats des analyses multiniveaux, en considérant les variations entre les 54 équipes de travail, ont suggéré un effet direct de la déviance interpersonnelle sur les agressions psychologiques. Les résultats ont aussi révélé que l’identité professionnelle et sa fragilisation prédisposent aux agressions, notamment une faible intégration des différences dans l’équipe, ainsi qu’un soutien social insuffisant. Tandis qu’une utilisation des compétences plus forte et une faible préoccupation pour le groupe s’associent aux agressions sexuelles dans les métiers spécialisés. De plus, une faible estime publique du métier s’associe à des agressions physiques, alors que des demandes élevées au travail et l’insécurité d’emploi s’associent à des agressions psychologiques. Enfin, les modèles multiniveaux ont associé le fait d’être une femme aux agressions physiques et sexuelles.
Les conclusions de cette recherche corroborent l’importance d’agir sur les dimensions identitaires afin de réduire les agressions, particulièrement en misant sur l’inclusion des travailleurs dans les processus innovants et sur une plus grande ouverture de leur part aux nouvelles idées. Au niveau de la culture des métiers spécialisés, il serait également judicieux de privilégier les valeurs dites plus féminines basées sur la collaboration, l’empathie et le soutien.

Published: April 2020

Many large cities in North America have jurisdiction over licensing rules that shape the employment and health conditions of ride-hail and taxi drivers. Yet there is a lack of research on the role of licensing agencies relating to the occupational health and safety (OHS) of taxi drivers. Most taxi and ride-hail drivers in Canada are self-employed workers and are, by default, exempt from OHS and worker compensation laws. Additionally, municipal licensing regimes in Canada and the US have undergone various changes as a result of pressures from new platform-based ride-hail services, like Uber and Lyft.The analysis is part of a larger study on the health and safety conditions faced by ride-hail drivers. The research approach adopted a multi-level sampling and analysis strategy with the aim of connecting taxi drivers’ everyday work experiences to company and sector practices, and with various regulatory arenas, including municipal licensing, taxation and car insurance. In this paper, the analysis draws from in-depth interviews at these different levels: with taxi and ride-hail drivers, with taxi and ride-hail managers, and with key informants in government, law, insurance, tax and elsewhere.The paper identifies features and impacts of municipal deregulation in the era of on-demand taxi services, focusing on a large Canadian city in a province where municipal authorities regulate the vehicle-for-hire sector. The research identified regulatory changes that included removing centralized taxi vehicle inspections, cancelling mandatory driver training, and instigating rapid changes to competition in the taxi workforce by issuing unlimited numbers of ride-hail licenses. Our analysis indicates that regulatory changes adopted by the city administration have compounded work vulnerabilities and hazards for taxi drivers, while extending hazardous conditions to ride-hail drivers. These hazards suggest the need for interventions at a range of levels, actors and agencies, rather than solely by city licensing officials.

AbstractPerovskite materials serve as promising candidates for display and lighting due to their excellent optical properties, including tunable bandgaps and efficient luminescence. However, their efficiency and stability must be improved for further application. In this work, quasi‐two‐dimensional (quasi‐2D) perovskites embedded in different polymers are prepared by inkjet printing to construct any luminescent patterns/pictures on the polymer substrates. The optimized quantum yield reaches over 65% by polyvinyl‐chloride‐based quasi‐2D perovskite composites. In addition, as‐fabricated perovskite−polymer composites with patterns show excellent resistance to abrasion, moisture, light irradiation, and chemical erosion by various solvents. Both quantum yield and lifetime are superior to those reported to date. These achievements are attributed to the introduction of the PEA+cations to improve the luminance and stability of perovskite. This patterned composite can be useful for color‐conversion films with low cost and large‐scale fabrication.

AbstractRecently, a printable power source that can be implemented on demand in integrated circuitries has gained tremendous attention to facilitate next‐generation, form‐factor free, miniaturized electronic systems. Among various energy storage units, a solid‐state micro‐supercapacitor with in‐plane device architecture has been recognized as a viable candidate with characteristic advantages of long cycle life‐time, high frequency response, and fast charge/discharge rate. However, to date, high performance, all‐printed micro‐supercapacitors have rarely been reported owing to an absence of printable current collector materials that can sustain high voltage conditions. In this study, a multidimensional printable particle mixture comprising Ni nanoparticles, Ni flakes, and a photoreactive polymer, polyvinylpyrrolidone is proposed. The highly conductive, printed metallic current collector is generated with a conductive surface passivation layer in a timescale of 10−3 s by flash‐light sintering process. It is revealed that the resulting metallic current collector is stable at a voltage as high as 3 V in the carbon electrode‐based device, enabling the fabrication of an all‐printed solid‐state micro‐supercapacitor with an areal energy density of 79–23 mJ cm−2 at an areal power density of 0.4–12.8 mW cm−2. Arbitrarily designed device circuits can be generated on demand simply by using a digitally programmable printing process, without incorporation of additional interconnection lines.

AbstractDespite the ever‐growing demand for Li metals as next‐generation Li battery electrodes, little attention has been paid to their oxidation stability, which must be achieved for practical applications. Here, a new class of printable solid electrolyte interphase mimic (pSEI) for antioxidative Li metal electrodes is presented. The pSEI (≈1 µm) is directly fabricated on a thin Li metal electrode (25 µm) by processing solvent‐free, UV polymerization‐assisted printing, exhibiting its manufacturing simplicity and scalability. The pSEI is rationally designed to mimic a typical SEI comprising organic and inorganic components, in which ethoxylated trimethylolpropane triacrylate and diallyldimethylammonium bis(trifluoromethanesulfonyl)imide are introduced as an organic mimic (acting as a moisture‐repellent structural framework) and inorganic mimic (allowing facile Li‐ion transport/high Li+ transference number), respectively. Driven by the chemical/architectural uniqueness, the pSEI enables the thin Li metal electrode to show exceptional antioxidation stability and reliable full cell performance after exposure to humid environments.

Abstract[001]C‐Textured 0.55Pb(Ni1/3Nb2/3)O3–0.15PbZrO3–0.3PbTiO3 (PNN‐PZT) ceramics are prepared by the templated grain‐growth method using BaTiO3 (BT) platelet templates. Samples with different template contents are fabricated and compared in terms of texture fraction, microstructure, and piezoelectric, ferroelectric and dielectric properties. High piezoelectric performance (d33 = 1210 pC N−1, d33* = 1773 pm V−1 at 5 kV cm−1) and high figure of merit g33⋅d33 (21.92 × 10−12 m2 N−1) are achieved in the [001]C‐textured PNN‐PZT ceramic with 2 vol% BaTiO3 template, for which the texture fraction is 82%. In addition, domain structures of textured PNN‐PZT ceramics are observed and analyzed, which provide clues to the origin of the giant piezoelectric and electromechanical coupling properties of PNN‐PZT ceramics.

AbstractConventional bone composites consistently fail to mimic the chemical composition and integrated organic/inorganic structure of natural bone, lacking sufficient mechanics as well as inherent osteoconductivity and osteoinductivity. Through a facile surface coating process, the strong adhesive, tannic acid (TA), is adhered to the surface of the natural bone component, hydroxyapatite (HA), with and without the immobilization of in situ formed silver nanoparticles. Residual functional groups available on the immobilized TA substituents are subsequently covalently linked to the citrate‐based biodegradable polymer, poly(octamethylene citrate) (POC), effectively bridging the organic and inorganic phases. Due to the synergistic effects of the tannin and citrate components, the obtained citrate‐based tannin‐bridged bone composites (CTBCs) exhibit vastly improved compression strengths up to 323.0 ± 21.3 MPa compared to 229.9 ± 15.6 MPa for POC‐HA, and possess tunable degradation profiles, enhanced biomineralization performance, favorable biocompatibility, increased cell adhesion and proliferation, as well as considerable antimicrobial activity. In vivo study of porous CTBCs using a lumbar fusion model further confirms CTBCs' osteoconductivity and osteoinductivity, promoting bone regeneration. CTBCs possess great potential for bone regeneration applications while the immobilized TA additionally preserves surface bioconjugation sites to further tailor the bioactivity of CTBCs.

AbstractNanoenzymes perceive the properties of enzyme‐like catalytic activity, thereby offering significant cancer therapy potential. In this study, Fe3O4@MnO2, a magnetic field (MF) targeting nanoenzyme with a core‐shell structure, is synthesized and applied to radiation enhancement with using glucose oxidase (GOX) for combination therapy. The glucose is oxidized by the GOX to produce excess H2O2 in an acidic extracellular microenvironment, following which the MnO2 shell reacts with H2O2 to generate O2 and overcome hypoxia. Concurrently, intracellular glutathione (GSH)—which limits the effects of radiotherapy (RT)—can be oxidized by the MnO2 shell while the latter is reduced to Mn2+ for T1‐weighed MRI. The core Fe3O4, with its good magnetic targeting ability, can be utilized for T2‐weighed MRI. In summary, the work demonstrates that Fe3O4@MnO2, as a dual T1‐ and T2‐weighed MRI contrast agent with strong biocompatibility, exhibits striking potential for radiation enhancement under magnetic targeting.
