Perceived Reportability of Intimate Partner Violence against Women to the Police and Help-seeking: A National Survey.

The literature has consistently found that victims of intimate partner violence (IPV) against women are reluctant to make their situation visible and report it to the police. Whether victims perceive and define IPV behaviors as reportable is key to understanding in which cases the police are seen as potential providers of help or whether other potential sources of help (family, friends, professionals, etc.) are preferred. The purpose of the present study was to analyze the influence of perceived reportability of IPV on women's selection of the police as a source of help compared to not seeking help or selecting other sources of help. Structural equation modeling was applied to data from 479 female participants drawn from a nationally representative sample of 1,112 male and female Chilean adolescents and young adults conducted by the National Youth Institute of Chile. The results showed that perceived reportability was a significant predictor of choosing the police as a source of help compared to other informal sources of help, such as family and friends. However, perceived reportability did not affect help-seeking choices between the police and other formal help sources (psychologists, public services). Participants' IPV victimization and attitudes toward IPV also played a specific role in selecting the police as a source of help. These findings highlight the complexity of the visibility of women's IPV victimization to the police and the need to examine its explanatory mechanisms.

Las publicaciones científicas señalan sistemáticamente la reticencia de las víctimas de violencia de pareja contra las mujeres a hacer visible su situación y denunciarla ante la policía. El hecho de que las víctimas perciban y definan las conductas de violencia de pareja como denunciables es clave para comprender en qué casos se considera a la policía como posible proveedora de ayuda o si se prefieren otros potenciales proveedores de ayuda (familiares, amigos, especialistas, etc.). El objetivo de la presente investigación ha sido analizar la influencia de la percepción de la capacidad de denunciar la violencia de pareja en la selección de la policía como proveedora de ayuda por parte de las mujeres, en comparación con la falta de búsqueda de ayuda o la selección de otros proveedores de la misma. Se han analizado los datos de 479 mujeres participantes en el estudio de una muestra representativa nacional de 1,112 adolescentes y jóvenes chilenos de ambos sexos realizado por el Instituto Nacional de la Juventud de Chile. Los resultados mostraron que la capacidad de denuncia percibida predice la selección de la policía como proveedor de ayuda en comparación con otras fuentes informales de ayuda, como la familia o los amigos. Sin embargo, no pareció tener efecto en la selección de la búsqueda de ayuda comparar a la policía con otras fuentes formales de ayuda (psicólogos, servicios públicos). La victimización y las actitudes hacia la violencia de pareja también desempeñan un papel específico en la selección de la policía como proveedora de ayuda. Los resultados demuestran la complejidad de la visibilidad para la policía de la violencia en la pareja contra las mujeres y la necesidad de examinar sus mecanismos explicativos.

Organ xenotransplantation acceptance in veterinary students: A multicentric opinion study in Spain.

BACKGROUND: The shortage of available transplant organs has made it necessary to search for alternatives, one of which is xenotransplantation. However, the use of animal organs could face rejection from society and the personnel involved in its implementation. OBJECTIVES: (a) to analyze the attitudes of Veterinary Degree students in six Spanish Universities towards xenotransplantation; and (b) to determine the factors that affect its acceptance. METHODS: Of the 2815 students surveyed in the degree program, 2683 valid surveys were obtained. Attitudes towards organ xenotransplantation were evaluated using a validated questionnaire of organ donation. RESULTS: If xenotransplantation was confirmed as a clinical reality, 93% (n = 2493) of those surveyed would accept a xenotransplanted organ, whilst 7% would not. If the results of xenotransplantation were worse than those obtained with human donors and it entailed more risk, 12% (n = 318) would be in favor. 56% (n = 1497) of the students would accept a xenotransplantation provisionally pending the arrival of a human organ. Attitudes towards xenotransplantation were affected by the academic year in which a student was studying, with more favorable attitudes among students in the last year (88% in first year vs. 95% in fifth year; p < .001). More favorable attitudes are also observed depending on the attitude they have towards organ transplantation, with those students being more in favor of donating their organs when they die (94% vs. 88%; p < .001). CONCLUSION: Veterinary students would have a very favorable attitude toward xenotransplantation if these animal organs functioned as well as human organs. Therefore, these students could play an important role in the future promotion of this technique.

Shepherds View of Large Carnivore Recovery in the Pyrenees, Spain.

The studied farms are small family businesses, and so, in more than half of the cases, their continuity is not guaranteed. Livestock management is typical of a mountain system, in which the animals graze throughout the year in cultivated fields, sown meadows, forests near the farms, and mountain pastures during the three summer months. The herds always have the constant surveillance of a shepherd. Farmers consider the current infrastructure present in mountain grasslands insufficient to facilitate the management and care of their herd. Their activity conflicts with various species of wildlife, such as the wild boar, Sus scrofa, roe deer, Capreolus capreolus, or griffon vulture, Gyps fulvus, and large carnivores such as the brown bear, Ursus arctos, or the grey wolf Canis lupus, despite all of them taking preventive measures to defend their herds from predators. The most widely used prevention measures are the presence of mastiff dogs, Canis lupus familiaris, next to the herds and the use of electric fencing to lock up livestock at night. Farmers reject the presence of bears and wolves in their area, considering it a real threat to the continuity of their economic activity, which presents a high degree of vulnerability.

Advantages of using relevant nearly optimal solutions in multi-objective tuning of robust controllers.

This paper presents a new approach for the multiobjective optimal design of robust controllers in systems with stochastic parametric uncertainty. Traditionally, uncertainty is incorporated into the optimization process. However, this can generate two problems: (1) low performance in the nominal scenario; and (2) high computational cost. For the first point, it is possible to ensure that the controllers produce an acceptable performance for the nominal scenario in exchange for being lightly robust. For the second point, the methodology proposed in this work reduces the computational cost significantly. This approach addresses uncertainty by analyzing the robustness of optimal and nearly optimal controllers in the nominal scenario. The methodology guarantees obtaining controllers that are similar/neighboring to lightly robust controllers. Two examples of controller design are shown: one for a linear model and another for a nonlinear model. Both examples demonstrate the usefulness of the proposed new approach.

Urban Itineraries with Smartphones to Promote an Improvement in Environmental Awareness among Secondary School Students.

Our world is undergoing a series of changes that are taking it to an unsustainable situation. In addition to alerting the population, we must seek education towards a more sustainable world. This research proposes the realization in Alcoy (Spain) of some urban itineraries with mobile devices and with secondary school students, in order to promote an improvement in awareness and action on environmental problems. This activity aims, among other objectives, through informal learning and outside the classroom, to raise awareness among secondary school students about the environmental problems that threaten us. With the completion of a questionnaire, after carrying out these urban itineraries, the results of 214 students confirm that, with this type of activity, there is a notable improvement in the level of awareness and concern for environmental problems. It is also detected that men prefer these types of environmental awareness tests, compared to women, who prefer tests that have a more creative and artistic theme. It is worth continuing to propose this type of activity among students and improve their approach by forecasting, planning, and improving the training of the teachers involved in it.

Influence of Job Insecurity on Musculoskeletal Disorders: A Mediation Model with Nursing Aides.

Work-related musculoskeletal disorders are some of the most prevalent diseases in the world. They have a multifactorial aetiology encompassing ergonomic and psychosocial risk factors. The aim of this study is to analyse the way job insecurity and physical workload are linked to musculoskeletal disorders, as well as the mediating role other psychosocial work risks can have on this potential relationship. A parallel mediation path regression analysis was designed using a sample of 457 nursing aides. The influence job insecurity and physical workload has on the onset of musculoskeletal symptoms together with the variables which mediate this relationship were examined. The results prove that both independent variables explain the onset of musculoskeletal symptoms in these professionals. The influence exerted by job insecurity is mediated by the social support received at work and the demands of the job. However, when analysing the physical workload, the social support received at work is not relevant as a mediator in this relationship. Job insecurity and physical workload are significant variables on the occurrence of musculoskeletal symptoms. The data obtained supports the need to focus on physical and psychosocial factors in order to prevent these disorders.

IgA vasculitis with nephritis (Henoch-Schönlein purpura) after COVID-19: A case series and review of the literature.

COVID-19 most related glomerular disease to date seems to be collapsing glomerulopathy, mostly in young Afroamerican patients with APOL1 gene risk alleles. However, in our population, predominant in elderly Caucasian patients, most biopsied pathology since the beginning of the pandemic has been IgA nephritis or Schönlein-Henoch purpura. Since the description of the first case of this entity after SARS-CoV-2 infection by our research group, three more cases have arisen, which are described in the following article. In contrast to the rest of IgA vasculitis cases reported, our patients presented more renal function deterioration and all of them required immunosupresive therapy. Moreover, some showed incomplete recovery of renal function. This case series strengthens the hypothesis that SARS-CoV-2 infection may be another trigger of this pathology.

Peer Victimization, Peer Aggression and Depressive Symptoms over Time: A Longitudinal Study with Latent Growth Curves

Most empirical research on the relationship between peer victimization, aggression, and mental health has been conducted with correlational designs. Much of this research has also focused primarily on linking peer victimization with either the potential aggressive behaviors of victims or a deterioration in their mental health. This study analyzes the relationship between peer victimization, peer aggression, and depressive symptoms in adolescents over time. The participants are 194 adolescents (49.2% boys, 50.8% girls) aged between 10 and 13 years (M = 10.88, SD = 0.84). The results of the growth modeling analysis indicate that the trajectories are interconnected: as victimization decreases, adolescent aggression and depressive symptoms also decrease. In addition, it is observed that victimization decreased in the same way in boys and girls, while aggression and depressive symptoms showed a smaller reduction in girls. Finally, the results and their potential practical implications are discussed. (AU)

Dichos estudios se ha centrado principalmente en vincular la victimización entre iguales y los posibles comportamientos agresivos de las víctimas o el deterioro de su salud mental. El estudio analiza la relación entre la victimización entre iguales, la agresión entre iguales y la sintomatología depresiva en adolescentes a lo largo del tiempo. Participan 194 adolescentes (49.2% chicos, 50.8% chicas) con edades comprendidas entre 10 y 13 años (M = 10.88, DT = 0.84). Los resultados del análisis del modelo de crecimiento indican que las trayectorias están interconectadas: a medida que disminuye la victimización, también disminuyen la agresión y la sintomatología depresiva. Además, se observa que la victimización disminuye de la misma manera en chicos que en chicas, mientras que la agresión y la sintomatología depresiva muestra una reducción menor en las chicas. Finalmente, se discuten los resultados y sus posibles implicaciones prácticas. (AU)

Emergency surgical treatment for active bleeding and anemia in patients with hemorrhoidal disease.

INTRODUCTION: The purpose of the study is to describe the clinical and surgical characteristics of patients with hemorrhoidal disease (HD), anemia, and active bleeding in need of urgent surgery. METHODS: It is a descriptive, retrospective study of 510 patients between 2015 and 2019. Male and female patients diagnosed with HD. The records of these patients were reviewed, and we identified those who underwent emergency surgery due to active bleeding, anemia, shock, and other clinical problems. Statistical analysis was carried out with the SPSS version 24 software. RESULTS: Fifty-three (10.3%) patients met the criteria for presenting active hemorrhoidal bleeding at the time of review and clinical and biochemical data of anemia. Patients presented a mean hemoglobin of 7.5 g/dl. The most frequent degree of HD was Grade II. The treatment received in 92.5% of the cases was hemorrhoidectomy with the Ferguson technique; in 5.7% (3), a hemorrhoidectomy was performed with an advanced energy device, and 1.9% (1) underwent the Milligan-Morgan technique. CONCLUSIONS: Emergency hemorrhoidectomy is the treatment of choice for patients with severe active bleeding from HD.

INTRODUCCIÓN: El propósito del estudio es describir las características clínicas y quirúrgicas de los pacientes con enfermedad hemorroidal, sangrado activo y anemia con necesidad de cirugía. METODOLOGÍA: Se trata de un estudio descriptivo y retrospectivo de 510 pacientes de ambos sexos diagnosticados con enfermedad hemorroidal entre 2015 y 2019. Se revisaron los expedientes de los pacientes sometidos a cirugía urgente con presencia de sangrado, anemia, choque y otros problemas clínicos. El análisis estadístico fue realizado con el software SPSS version 24. RESULTADOS: El 10.3% (53) de los pacientes fueron diagnosticados con sangrado hemorroidal activo al momento de la revisión y con datos clínicos y bioquímicos de anemia. El promedio de hemoglobina de estos fue de 7.5 g/dl. La enfermedad hemorroidal grado II fue la más frecuente. Se realizó hemorroidectomia tipo Ferguson en el 92.5% (49) de los casos; 5.7% (3) fueron operados con energía avanzada y solo 1.9% (1) con la técnica Milligan-Morgan. CONCLUSIONES: La hemorroidectomia de urgencia es el tratamiento de elección en el sangrado activo severo por enfermedad hemorroidal.

Analysis of the Relationship between Satisfaction with the Coach and the Effect of Comparative Social Feedback in Elite Female Handball Players.

This research aims at studying the effect of comparative feedback on psychological variables (competence valuation, perceived competence, autonomous motivation, amotivation, subjective well-being) and performance (throwing speed and accuracy). A total of 73 handball players from the highest Spanish handball (Iberdrola League) category participated in this study. After previously rating satisfaction with their head coach, they were indiscriminately assigned to one of three different experimental conditions measuring feedback, positive, negative, and none. There were significant differences in competence valuation, perceived competence, autonomous motivation, and throwing speed in the three feedback groups, more concretely, low satisfaction with the head coach. Positive effects were found when there was low satisfaction with the coach and positive feedback on the competence valuation, autonomous motivation, and throwing speed compared to negative or no feedback. These results have important implications for optimizing coaches' behaviors in relation to athlete well-being and performance.

Dyadic Analysis of Emotional Intimate Partner Violence: An Estimation of Dyadic Patterns and Influencing Individual, Family, and Couple Factors

Background: The co-occurrence of intimate partner violence (IPV) has been usually determined by co-occurring reports of perpetration and victimization, but still not considering the interdependence of both members’ reports. The current research aimed to analyze the dyadic patterns of IPV perpetration and victimization, considering the influence of sexism toward women, family functioning, and relationship duration. Method: The sample involved 242 couples heterosexual couples. The Actor-Partner Interdependence Model was calculated to analyze the violent dynamics in the couple. For males, a couple-oriented pattern was identified, but for females the pattern was between couple-oriented and actor-only pattern. Results: These patterns remained stable when personal, family, and relational variables were included in the model, which present different effects on perpetration and victimization: males’ hostile sexism predicted higher levels of male IPV perpetration and victimization as well as higher levels of male and female victimization via male perpetration. Regarding family functioning, higher family good functioning predicted lower IPV perpetration in males and lower victimization in females. Finally, relationship length predicted higher levels of IPV perpetration of both couple members and higher victimization via perpetration. Conclusions: These results are discussed in light of the interdependence of couple members’ IPV perpetration and victimization. (AU)

Antecedentes: La coocurrencia de la violencia en la pareja (IPV) suele establecerse con el informe de ambos miembros de la pareja, pero rara vez se tiene en cuenta la interdependencia entre sus respuestas. El objetivo del trabajo ha sido analizar los patrones diádicos de la IPV teniendo en cuenta el sexismo hacia las mujeres, la funcionalidad familiar y la duración de la relación. Método: La muestra estaba compuesta por 242 parejas heterosexuales, utilizándose el Actor-Partner Interdependence Model para analizar los patrones diádicos. En el caso de los hombres se identificó el patrón orientado a la díada, mientras que el patrón de las mujeres parecía encontrarse entre el orientado a la díada y al actor. Resultados: Estos patrones se mantuvieron tras haber incluido el sexismo, el funcionamiento familiar y la duración de la relación: el sexismo hostil de los hombres predecía mayores niveles de perpetración en ellos y de victimización en ambos a través de la perpetración de los hombres. El buen funcionamiento familiar predecía una menor perpetración en los hombres y victimización en las mujeres. Finalmente la duración de la relación predijo mayores niveles de perpetración y victimización a través de la perpetración en ambos miembros de la pareja. Conclusiones: Se discuten los resultados a partir de la interdependencia de la IPV de ambos miembros de la pareja. (AU)

Vasculitis IgA con nefritis (púrpura de Schönlein-Henoch) tras COVID-19: una serie de casos y revisión de la literatura / IgA vasculitis with nephritis (Henoch-Schönlein purpura) after COVID-19: A case series and review of the literature

La patología glomerular más relacionada con enfermedad COVID-19 hasta la fecha parece ser la glomerulopatía colapsante, principalmente en pacientes de raza afroamericana y con alelos de riesgo para el gen APOL1. No obstante, en nuestra población, conformada por pacientes adultos mayores de raza caucásica, la patología más biopsiada desde el inicio de la pandemia ha sido la nefritis IgA o púrpura de Schönlein-Henoch.Desde la descripción del primer caso de esta entidad tras infección por SARS-CoV-2 por nuestro grupo de investigación hemos objetivado otros tres, los cuales se describen a continuación. En contraste con el resto de los casos publicados de vasculitis IgA, nuestros pacientes presentaban mayor deterioro de función renal y todos requirieron tratamiento inmunosupresor. Además, algunos presentaron recuperación incompleta de función renal. Esta serie de casos afianza la posibilidad de que la infección por SARS-CoV-2 sea un desencadenante más de esta patología. (AU)

A dataset of aerial photographs of 1972 from an irrigated area in Monegros, Spain.

Our dataset contains the scans of 278 paper prints of contacts from a photogrammetric flight of 1972, plus a diagram for the relative location of each of the photograms. The paper prints served three years later, i.e. in 1975, for studying the soils of an irrigated district. The entire flight covered about 705 km2, in the semiarid Central Ebro Basin, at the province of Huesca, Spain. The flight encompasses the 359 km2-irrigated district fed by the sections 2nd and 3rd of the first part of the Canal of Monegros, plus the westward conterminous non-irrigated lands until the border with the province of Zaragoza (Fig. 1). The Spanish Ministry of Agriculture throughout its now extinct branch Institute for Agrarian Reform and Development, i.e. IRYDA by its Spanish acronym, contracted a consulting company to produce a report [1] about the location of saline and non-saline soils of the district in 1975. The soil surveyors used the paper prints for preparing the report and marked some of the prints with color wax-pencil. Most of these marks locate the sampled sites but also appear geographical names, schematic highlights of some terrain features, and mentions to ongoing land levelling or similar works.

Immune responses to mRNA vaccines against SARS-CoV-2 in patients with immune-mediated inflammatory rheumatic diseases.

BACKGROUND: Patients with immune-mediated rheumatic diseases (IMRDs) are commonly treated with immunosuppressors and prone to infections. Recently introduced mRNA SARS-CoV-2 vaccines have demonstrated extraordinary efficacy across all ages. Immunosuppressed patients were excluded from phase III trials with SARS-CoV-2 mRNA vaccines. AIMS: To fully characterise B-cell and T-cell immune responses elicited by mRNA SARS-CoV-2 vaccines in patients with rheumatic diseases under immunotherapies, and to identify which drugs reduce vaccine's immunogenicity. METHODS: Humoral, CD4 and CD8 immune responses were investigated in 100 naïve patients with SARS-CoV-2 with selected rheumatic diseases under immunosuppression after a two-dose regimen of SARS-CoV-2 mRNA vaccine. Responses were compared with age, gender and disease-matched patients with IMRD not receiving immunosuppressors and with healthy controls. RESULTS: Patients with IMRD showed decreased seroconversion rates (80% vs 100%, p=0.03) and cellular immune responses (75% vs 100%, p=0.02). Patients on methotrexate achieved seroconversion in 62% of cases and cellular responses in 80% of cases. Abatacept decreased humoral and cellular responses. Rituximab (31% responders) and belimumab (50% responders) showed impaired humoral responses, but cellular responses were often preserved. Antibody titres were reduced with mycophenolate and azathioprine but preserved with leflunomide and anticytokines. CONCLUSIONS: Patients with IMRD exhibit impaired SARS-CoV-2 vaccine immunogenicity, variably reduced with immunosuppressors. Among commonly used therapies, abatacept and B-cell depleting therapies show deleterious effects, while anticytokines preserved immunogenicity. The effects of cumulative methotrexate and glucocorticoid doses on immunogenicity should be considered. Humoral and cellular responses are weakly correlated, but CD4 and CD8 tightly correlate. Seroconversion alone might not reflect the vaccine's immunogenicity.

Smartphone Addiction, Social Support, and Cybercrime Victimization: A Discrete Survival and Growth Mixture Model

In recent decades, criminological theories have identified a set of vulnerabilities in potential victims that seek to explain their victimization. When it comes to explaining cybercrime victimization, however, the important role that addiction to the vulnerabilities associated with technological devices can play has tended to be overlooked. In this paper we empirically link smartphone addiction, social support, and cyberfraud victimization in a nationally representative sample of 716 smartphone users followed for three years. The results of discrete survival and growth mixture models suggest that the probability of cyberfraud victimization is lower among users with a decrease in smartphone addiction and an increase in social support over the three years. These results allow us to suggest new avenues in the study of cybercrime victimization, with special emphasis on the psychosocial consequences that the deregulated use of these technological devices may entail. (AU)

En las últimas décadas, las teorías criminológicas han identificado una serie de vulnerabilidades en las víctimas potenciales que tratan de explicar su victimización. Sin embargo, cuando se trata de explicar la victimización por ciberdelincuencia, se ha tendido a pasar por alto el importante papel que puede desempeñar la adicción a los dispositivos tecnológicos y sus consecuencias psicosociales. En este trabajo relacionamos empíricamente la adicción a los smartphones, el apoyo social y la victimización por ciberdelincuencia en una muestra representativa a nivel nacional de 716 usuarios a los que se siguió durante tres años. Los resultados de los modelos de curvas de supervivencia para tiempo discreto y mixtura de crecimiento latente sugieren que la probabilidad de victimización por ciberfraude es menor entre los usuarios con una disminución de la adicción a los teléfonos inteligentes y un aumento del apoyo social a lo largo de los tres años. Estos resultados nos permiten sugerir nuevas vías en el estudio de la victimización por ciberdelincuencia, con especial énfasis en las consecuencias psicosociales que puede conllevar el uso desregulado de estos dispositivos tecnológicos.

Dating Violence Questionnaire for Victimization and Perpetration (DVQ-VP): An Interdependence Analysis of Self-Reports / Dating Violence Questionnaire for Victimization and Perpetration (DVQ-VP): un análisis de la interdependencia de los autoinformes en parejas

Antecedentes/Objetivo: Aunque existen instrumentos de medida de la violencia en la pareja (IPV), no se ha evaluado su validez considerando la interdependencia entre los autoinformes de victimización y perpetración con datos diádicos. El objetivo fue evaluar la validez y fiabilidad del Cuestionario de Violencia entre Novios (CuViNo) incluyendo la interdependencia entre los autoinformes de victimización y perpetración de los miembros de parejas actuales. Método: Seiscientas dieciséis parejas heterosexuales de adultos jóvenes participaron en el estudio. Cada participante respondió de manera independiente a las versiones de victimización y perpetración del CuViNo. Resultados: El modelo de interdependencia victimización-perpetración basado en datos diádicos mostró un buen ajuste a los datos e invarianza entre sexos. Todos los factores correlacionaron significativamente y fueron fiables. Conclusiones: El CuViNo es un instrumento válido y fiable para la medición independiente de perpetración y victimización de IPV en adolescentes y adultos-jóvenes, pero también para la medición interdependiente de ambas. El CuViNo también es invariante entre sexos, lo que permite comparar los resultados de hombres y mujeres. Estos resultados muestran la relevancia de tener en cuenta la interdependencia entre victimización y perpetración, así como de cuidar la excesiva confianza en los autoinformes individuales centrados en la perpetración o la victimización a la hora de alcanzar un conocimiento preciso.

Background/Objective: Although measurement instruments for intimate partner violence (IPV) are available, their validity considering the interdependence of victimization and perpetration self-reports based on dyadic reports has not been tested. The aim was to test the validity and reliability of a new version of the Dating Violence Questionnaire (DVQ–R) that includes the interdependence of victimization and perpetration self-reports using current couple information. Method: Participants were young adults comprising 616 current heterosexual couples. Each dyad member responded to the victimization and perpetration versions of the DVQ-R independently from their partner. Results: The victimization-perpetration interdependence model based on dyadic data showed a good fit to the data and was invariant across sexes. All the factors were significantly correlated with each other and were reliable. Conclusions: The DVQ is a valid and reliable measurement instrument for the independent assessment of IPV perpetration and victimization in adolescent and young adult populations and an interdependent measure of IPV victimization and perpetration. The DVQ–VP is invariant across sexes, which makes the results obtained for males and females comparable. These results show the relevance of considering perpetration and victimization together and emphasize the necessity to be cautious regarding the excessive reliability of individual self-reported perpetration or victimization to obtain more precise knowledge.
