Violencia sexual y jóvenes: «no es algo con lo que naces, sino con lo que aprendes» / Sexual violence and young people: “it is not something you are born with, but with what you learn”

Objetivo: Analizar las percepciones y experiencias de la población joven en España sobre la violencia sexual (VS), sus posibles causas, víctimas y perpetradores. Método: Estudio cualitativo basado en entrevistas semiestructuradas a 22 jóvenes de entre 18 y 24 años. Se llevó a cabo un análisis del contenido cualitativo. Resultados: En las narrativas juveniles destacan la indefinición y la inconcreción sobre lo que es la VS, excepto cuando mencionan la violación, la falta de consentimiento y el uso de la fuerza en las relaciones sexuales. Las chicas, interpeladas como principales víctimas, aportan una visión más amplia y vinculada a las desigualdades de género. En general, predomina la idea de que la VS es perpetrada por hombres contra mujeres en relaciones heterosexuales dentro y fuera de la pareja. En las explicaciones, conviven las referencias a factores tanto contextuales (ligados a las desigualdades de género y la construcción social de las relaciones sexuales) como conductuales (que incluyen el visionado de pornografía). También emergen algunas estrategias relacionadas con la educación sexual y afectiva. Conclusiones: En las percepciones de las personas jóvenes participantes en este estudio parecen convivir la ambigüedad con referencias explícitas a las diferentes formas en las que se manifiesta la VS y la influencia de las desigualdades de género. El sexo y la experiencia vital parecen influir en estas narrativas. Se requiere el fomento de una perspectiva más crítica sobre la construcción social de la VS y las relaciones íntimas en la población joven.(AU)

Objective: To analyse the perceptions and experiences of young people in Spain about sexual violence (SV), its possible causes, victims and perpetrators.Method: Qualitative study based on semi-structured interviews with 22 young people between 18 and 24 years old. A qualitative content analysis was carried out. Results: In the juvenile narratives, the lack of definition and accuracy about what SV is stands out, except for mentioning rape, lack of consent and use of force in sexual relations. The girls, self-perceived as the main victims, also break with these narratives by providing a broader vision and gender inequalities related. In general, the most prevailed idea is that VS is perpetrated by men against women in heterosexual relationships inside and outside the couple. Regarding explanations, references coexist to both contextual factors (linked to gender inequalities and the social construction of sexual relationships) and behavioural factors (which includes the viewing of pornography). Tentatively proposals for improvement related to sexual and affective education emerge. Conclusions: In the perceptions of the young people, ambiguity seems to coexist with explicit references to the different ways in which it manifests itself and the influence of gender inequalities. Sex and life experience appear to influence these narratives. It is necessary to promote a more critical perspective on the social construction of SV and intimate relationships in the young population.(AU)

Assessing the relationship between agency and peer violence among adolescents aged 10 to 14 years in Kinshasa, Democratic Republic of Congo and Blantyre, Malawi: A cross-sectional study.

BACKGROUND: Interpersonal violence has physical, emotional, educational, social, and economic implications. Although there is interest in empowering young people to challenge harmful norms, there is scant research on how individual agency, and, specifically, the "power to" resist or bring about an outcome relates to peer violence perpetration and victimization in early adolescence. This manuscript explores the relationship between individual agency and peer violence perpetration and victimization among very young adolescents (VYAs) living in two urban poor settings in sub-Saharan Africa (Kinshasa, Democratic Republic of Congo (DRC) and Blantyre, Malawi). METHODS AND FINDINGS: The study draws on two cross-sectional surveys including 2,540 adolescents 10 to 14 years from Kinshasa in 2017 (girls = 49.8% and boys = 50.2%) and 1,213 from Blantyre in 2020 (girls = 50.7% and boys = 49.3%). The sample was school based in Malawi but included in-school and out-of-school participants in Kinshasa due to higher levels of early school dropout. Peer violence in the last 6 months (dependent variable) was defined as a four categorical variable: (1) no victimization or perpetration; (2) victimization only; (3) perpetration only; and (4) both victimization and perpetration. Agency was operationalized using 3 scales: freedom of movement, voice, and decision-making, which were further divided into tertiles. Univariate analysis and multivariable multinomial logistic regressions were conducted to evaluate the relationships between each agency indicator and peer violence. The multivariable regression adjusted for individual, family, peer, and community level covariates. All analyses were stratified by gender and site. In both sites, adolescents had greater voice and decision-making power than freedom of movement, and boys had greater freedom of movement than girls. Boys in both settings were more likely to report peer violence in the last six months than girls (40% to 50% versus 32% to 40%, p < 0.001), mostly due to higher rates of a perpetration-victimization overlap (18% to 23% versus 10% to 15%, p < 0.001). Adolescents reporting the greatest freedom of movement (Tertile 3) (with the exception of girls in Kinshasa) had a greater relative risk ratio (RRR) of reporting a perpetrator-victim overlap (boys Kinshasa: RRR = 1.9 (1.2 to 2.8, p = 0.003); boys Blantyre: RRR = 3.8 (1.7 to 8.3, p = 0.001); and girls Blantyre: RRR = 2.4 (1.1 to 5.1, p = 0.03)). Adolescents with the highest decision-making power in Kinshasa also had greater RRR of reporting a perpetrator-victim overlap (boys: RRR = 3.0 (1.8 to 4.8, p < 0.001). Additionally, girls and boys in Kinshasa with intermediate decision-making power (tertile 2 versus 1) had a lower RRR of being victimized (Girls: RRR = 1.7 (1.02 to 2.7, p = 0.04); Boys: RRR = 0.6 (0.4 to 0.9, p = 0.01)). Higher voice among boys in Kinshasa (Tertile 2: RRR = 1.9 (1.2 to 2.9, p = 0.003) and Tertile 3: 1.8 (1.2 to 2.8, p = 0.009)) and girls in Blantyre (Tertile 2: 2.0 (1.01 to 3.9, p = 0.048)) was associated with a perpetrator-victim overlap, and girls with more voice in Blantyre had a greater RRR of being victimized (Tertile 2: RRR = 1.9 (1.1 to 3.1, p = 0.02)). Generally, associations were stronger for boys than girls, and associations often differed when victimization and perpetration occurred in isolation of each other. A main limitation of this study is that the cross-sectional nature of the data does not allow a causal interpretation of the findings, which need further longitudinal exploration to establish temporality. CONCLUSIONS: In this study, we observed that peer violence is a gendered experience that is related to young people's agency. This stresses the importance of addressing interpersonal violence in empowerment programs and of including boys who experience the greatest perpetration-victimization overlap.

Invariance of the WHO violence against women instrument among Kenyan adolescent girls and young women: Bayesian psychometric modeling.

INTRODUCTION: To make valid comparisons across groups, a measurement instrument needs to be measurement invariant across those groups. The present study evaluates measurement invariance for experience of violence among adolescent girls and young women (AGYW) in two informal settlements in Nairobi, Kenya. METHODS: We used survey data collected from 1,081 AGYW aged 15-22 years from two Nairobi's informal settlements of Korogocho (n = 617) and Viwandani (n = 464) in 2017 through DREAMS (an initiative aimed at reducing HIV incidence among AGYW with a core package of evidence-based interventions) impact evaluation project. Experience of violence was measured using the 15-item WHO's violence against women instrument, and factorial (non)invariance assessed within exploratory structural equation modeling (ESEM) framework. Cross-group measurement invariance was assessed using Bayesian Multiple Indicator Multiple Causes (MIMIC) model across site, age groups, self-reported invitation to participate in DREAMS, marital status, currently in school, education level, religion, ethnic groups, ever had sex, slept hungry at night past 4 weeks, and wealth index. RESULTS: The mean and median ages of the AGYW were 17.9 years and 17 years, respectively. About 59% reported having had sex and 58% of AGYW were in school. The percentage reporting each act of violence varied from 1.6% ("attacked you with a weapon") to 26.5% ("insult you or make you feel bad about yourself"). About 44% (n = 474) of participants experienced ≥1 acts of violence, and 2.7% (n = 29) experienced at least half of the 15 acts. The structure underlying the 15 items was configurally similar to that proposed by WHO, with three factors reflecting either psychological, physical, or sexual violence. Noninvariance was detected for five items-spread across the three domains. Three of five items showed noninvariance only for sleeping hungry at night in the past 4 weeks. As the majority of items did not show evidence of noninvariance, differences in latent mean scores likely reflect actual differences and may not be attributable to measurement artifacts. CONCLUSIONS: Using state-of-the-art statistical techniques on a widely used instrument for measuring exposure to violence among women, this study provides support for the subscales of psychological, physical and sexual violence in a Kenyan AGYW population. The instrument supports comparisons across groups within this population. This is crucial when comparing violence against girls/women prevalence rates and to understand challenges and exchange strategies to reduce abuse or violence experienced by AGYW, or women in general.

Patient reported outcomes 6 to 12 months after interpersonal violence: A multicenter cohort study.

PURPOSE: Violence continues to be a significant public health burden, but little is known about the long-term outcomes of these patients. Our goal was to determine the impact of violence-related trauma on long-term functional and psychosocial outcomes. METHODS: We identified trauma patients with moderate to severe injuries (Injury Severity Score, ≥9) treated at one of three level 1 trauma centers. These patients were asked to complete a survey over the phone between 6 and 12 months after injury evaluating both functional and psychosocial outcomes (12-item Short Form Survey, Trauma Quality of Life, posttraumatic stress disorder [PTSD] screen, chronic pain, return to work). Patients were classified as having suffered a violent injury if the mechanism of injury was a stab, gunshot, or assault. Self-inflicted wounds were excluded. Adjusted logistic regression models were built to determine the association between a violent mechanism of injury and long-term outcomes. RESULTS: A total of 1,050 moderate to severely injured patients were successfully followed, of whom 176 (16.8%) were victims of violence. For the victims of violence, mean age was 34.4 years (SD, 12.5 years), 85% were male, and 57.5% were Black; 30.7% reported newly needing help with at least one activity of daily living after the violence-related event. Fifty-nine (49.2%) of 120 patients who were working before their injury had not yet returned to work; 47.1% screened positive for PTSD, and 52.3% reported chronic pain. On multivariate analysis, a violent mechanism was significantly associated with PTSD (odds ratio, 2.57; 95% confidence interval, 1.59-4.17; p < 0.001) but not associated with chronic pain, return to work, or functional outcomes. CONCLUSION: The physical and mental health burden after violence-related trauma is not insignificant. Further work is needed to identify intervention strategies and social support systems that may be beneficial to reduce this burden. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

Violencia simbólica en Instituciones de Educación Superior. Experiencia de docentes de una Universidad Pública colombiana / Symbolic violence in higher education institutions. Experience of teachers from a public university

En las Instituciones de Educación Superior (IES) se presentan algunas formas de violencia directa, aunque poco se han estudiado otras formas de violencia como la simbólica. Objetivo: señalar, a partir de las experiencias de algunos docentes de educación superior, las manifestaciones de violencia simbólica presentes en su lugar de trabajo. Método: investigación de corte mixto enmarcada en el paradigma empírico analítico. Se utilizaron como instrumentos una encuesta estructurada aplicada a 200 docentes y una entrevista en profundidad en la que participaron cinco docentes de una IES pública en Colombia. Resultados: los hallazgos develan la presencia de ciertas formas de violencia simbólica en la IES que se traducen, principalmente, en limitaciones al ejercicio del libre desarrollo de cátedra, restricciones para opinar o presentar los puntos de vista, dificultades para el reconocimiento de la pluralidad ideológica, tratamiento diferencial por sexo y escasa importancia otorgada a algunas disciplinas. Conclusión: las universidades son estructuras jerárquicas de poder sobre las cuales pueden anidar formas particulares de violencia simbólica que exigen estrategias y líneas de acción particulares desde la gestión humana.

In Higher Education Institutions there are some forms of direct violence, although seldom nobody has been studied other forms of violence such as symbolic violence. Objective: to point out, based on the experiences of some higher education professors, the manifestations of symbolic violence present in their workplace. Method: research of mixed focus framed in the analytical empirical paradigm. The instruments used were a structured survey applied to 200 professors and an in-depth interview in which five professors from a public higher education institution in Colombia participated. Results: The findings reveal the presence of certain forms of symbolic violence in the HEI that are translated, mainly, in limitations to the exercise of the free development of the chair, restrictions to express their opinions or own points of view, difficulties in the recognition of ideological plurality, differential treatment by sex and not more importance given to some disciplines. Conclusion: universities are hierarchical structures of power on which special forms of symbolic violence can nest that require strategies and particular lines of action from human management.

Bullying in adolescents: role, type of violence and determinants. / Acoso escolar en adolescentes: rol, tipo de violencia y determinantes.

OBJECTIVE: To determine the prevalence of bullying and its determinants among adolescents attending school. METHOD: An analytical cross-sectional study was conducted with a sample of adolescents, who were selected using a multistage probability sampling, from 20 public educational institutions in a Colombian city, in which a simple and multivariate binomial regression was carried out. RESULTS: A total of 500 adolescents participated from which 50.4% were women and 53.2% in their middle adolescence. Verbal violence prevailed in 66.5%, followed by physical violence in 32.0% and social bullying in 30.6%. 69.5% of the adolescents have been witnesses, 35.8% victims, and 14.2% aggressors. 80.5% of the aggressors were victims of bullying. In the multivariate analysis, an association was found between being a victim and having disabilities (PR:2.4; CI: 1.6-3.7), verbal aggression in the home (PR: 1.7; CI: 1.2-2.3) and drug abuse (PR: 1.7; CI 1.1-2.8). Being an aggressor was also associated with being a victim (PR: 7.2; CI 3.6-14.3) and alcohol abuse (PR: 2.2; CI: 1.3-3.8). CONCLUSION: The frequency of bullying observed and the associated determinants demonstrate the persistence of this problem in adolescents and the need to develop a culture of appropriate and inclusive coexistence that goes beyond the school setting.

Co-occurrence of Dating Violence Victimization Subtypes: Assessing the Influence of Family Factors, Dating Attitudes, Risky Behaviors, and the Moderating Effect of Gender Among School-Aged Teens.

Using data from a nationally representative sample of school-aged teens (n = 795), this study examined covariates associated with three subtypes of dating violence victimization (physical violence, emotional abuse, and imposed isolation). We asked the research questions: What were the family factors, dating attitudes, and risky behaviors associated with three subtypes of dating violence victimization across two time points? Second, were these relationships moderated by gender? Overall, we found widespread co-occurrence of victimization. Contrary to our predictions, not all earlier experiences with dating violence victimization worsened or persisted overtime. Regarding family factors, we did not find substantial statistically significant effects on victimization, with the exception that greater openness with parents was associated with increased occurrence of emotional abuse at Wave 1. In terms of dating attitudes, we found that when respondents condoned violence against a girlfriend, they were more likely to experience physical violence victimization at both waves. Respondents who believed that it is okay to use violence to control a boyfriend's behavior were more likely to report emotional abuse at Wave 1. Similarly, respondents who believed that it is okay to date more than one person, as well as those who condoned sexual intercourse outside of a romantic relationship, were more susceptible to emotional abuse. Regarding risky behaviors, we found that the respondents' victimization experience did not increase with a greater sexual partner acquisition; rather, it exerted the opposite effect on their experience with physical violence victimization. These risky behaviors, however, were only statistically significant at Wave 1. Finally, the moderating effect of gender is noted in the study. Implications from the study are discussed.

The prevalence and patterns of exposure to interpersonal violence among men and women in Estonia.

BACKGROUND: To understand better the total burden of interpersonal violence on society, it is useful to assess the prevalence of interpersonal violence among both, men and women. Exposure to multiple forms of interpersonal violence, referred to as polyvictimization, has been associated with more severe health consequences than exposure to any form separately. The aims of this study were to assess the prevalence of emotional, physical and sexual interpersonal violence in childhood, adulthood and at both childhood and adulthood among men and women in Estonia, analyze the patterns of interpersonal violence and socio-demographic correlates of polyvictimization in adulthood by gender. METHODS: The analysis was based on two population-based, cross-sectional, self-administered surveys carried out among men and women in Estonia in 2014. In both surveys, the NorVold Abuse questionnaire was used to measure exposure to interpersonal violence. Men and women aged 18-44 were included to the analysis. RESULTS: Among men 66.6% and among women 54.2% had been exposed to at least one form of interpersonal violence during lifetime. Men had been more often exposed to isolated physical interpersonal violence, among women the distribution of different forms of interpersonal violence was more even and exposure to sexual violence was more common. The prevalence of polyvictimization in adulthood was two times higher among women compared to men and more socio-demographic correlates, were associated with it. Exposure to violence in childhood was associated with polyvictimization in adulthood across gender. CONCLUSIONS: The prevalence of interpersonal violence in Estonia is high among men and women. The most prevalent forms and patterns of interpersonal violence, however, differ by gender, as do the socio-demographic correlates. Screening for interpersonal violence, in childhood and adulthood, and gender-specific interventions are needed, especially for high-risk groups identified in this study. Primary prevention of childhood violence should be a priority, as it was associated with higher risk for exposure to violence later in life across gender.

Characteristics of interpersonal violence in adult victims at the Adult Emergency Trauma Centre (AETC) of Queen Elizabeth Central Hospital.

Introduction: Globally, the burden of interpersonal violence and its significant impact on mortality, morbidity and disability makes it a major public health problem which necessitates intervention. This article examines characteristics of victims of interpersonal violence and violent events in Malawi. The focus is on a population that has been traditionally neglected in literature. Methods: Queen Elizabeth Central Hospital (QECH) maintains a trauma registry with data that is prospectively collected. Patients offered trauma care after interpersonal violence from May 2013 to May 2015 were evaluated. Results: There were 1431 patients with violent events recorded at the Adult Emergency Trauma Centre (AETC) with a male predominance of 79.5%. The dominant age group was young adults between 25-29 years old (22%). Most attacks occurred during cold and dry season (46.9%) and most common location was on the road (37.2%). Alcohol use by victims was recorded in 10.5% of cases. Soft tissue injuries were the most common injuries sustained (74.1%). Most patients were treated as outpatients (80.9%). There were two deaths. At multivariate analysis, women had a lower risk of interpersonal violence as compared to men, (OR 0.82 [0.69-0.98]). Victims' use of alcohol was associated with increased risk of assault (OR 1.63 [1.27-2.10]). As compared to other places, odds of being assaulted were higher at home (OR 1.62 [1.27-2.06]) but lower at work (OR 0.68 [0.52-0.89) and on the road (OR 0.82 [0.65-1.03]). Odds of being assaulted were higher in the cold and dry season as compared to hot and dry season, (OR 1.26 [1.08-1.47]). Conclusion: Young males were most involved in interpersonal violence. Location of injury and seasonal variation were significant factors associated with interpersonal violence and most commonly sustained injuries were soft tissue injuries. These findings will help in identifying targeted interventions for interpersonal violence in Malawi and other low-and-middle-income countries (LMICs).

Secular Trends of Global Burden of Violence, 1990-2015: In Spite of Successes, Women and Children Are Highly Affected in Low- and the Middle-Income Countries.

BACKGROUND: Violence is a challenging modern epidemic worldwide. Less evidence is available on the populations most affected by violence in recent decades. The aim of the study was to ecologically investigate temporal trends of the global burden of violence according to gender, age group, and socio-demographic development. METHODS: Data on the age- and gender-specific rates of country-level disability adjusted life years (DALYs) attributable to different types of violence i.e. interpersonal violence (IV), and collective violence (CV) and legal interventions were retrieved from online database provided by the global burden of diseases project. Countries were categorized according to their socio-demographic index (SDI). Incidence rate ratio (IRR) per one year was estimated according to age groups, genders and SDI categories applying Poisson regression modeling. RESULTS: The highest decrease of the DALYs attributable to IV was observed for the under-five-years age group and then for 5-14-years in both genders, globally. Considering the CV, estimated IRRs were significant only for the under-five-years age group, which was at 1.30 (95% CI: 1.20, 1.40, per 10 years) for girls and 1.29 (95% CI: 1.21, 1.39, per 10 years) for boys. CONCLUSION: The rate of DALYs due to IV has been more decreasing among women and children during the recent decades. By the next 10 years, the attributed DALYs to CV would increase up to 120%. Children, adolescents and women are highly affected by CV in countries with middle-low and middle social development in the recent decades.

Classification and Prediction of Violence Against Chinese Medical Staff on the Sina Microblog Based on a Self-Organizing Map: Quantitative Study.

BACKGROUND: For the last decade, doctor-patient contradiction in China has remained prominent, and workplace violence toward medical staff still occurs frequently. However, little is known about the types and laws of propagation of violence against medical staff online. OBJECTIVE: By using a self-organizing map (SOM), we aimed to explore the microblog propagation law for violent incidents in China that involve medical staff, to classify the types of incidents and provide a basis for rapidly and accurately predicting trends in public opinion and developing corresponding measures to improve the relationship between doctors and patients. METHODS: For this study, we selected 60 cases of violent incidents in China involving medical staff that led to heated discussions on the Sina microblog from 2011 to 2018, searched the web data of the microblog using crawler software, recorded the amount of new tweets every 2 hours, and used the SOM neural network to cluster the number of tweets. Polynomial and exponential functions in MATLAB software were applied to predict and analyze the data. RESULTS: Trends in the propagation of online public opinion regarding the violent incidents were categorized into 8 types: bluff, waterfall, zigzag, steep, abrupt, wave, steep slope, and long slope. The communications exhibited different characteristics. The prediction effect of 4 types of incidents (ie, bluff, waterfall, zigzag, and steep slope) was good and accorded with actual spreading trends. CONCLUSIONS: Our study found that the more serious the consequences of a violent incident, such as a serious injury or death, the more attention it drew on the microblog, the faster was its propagation speed, and the longer was its duration. In these cases, the propagation types were mostly steep slope, long slope, and zigzag. In addition, the more serious the consequences of a violent incident, the higher popularity it exhibited on the microblog. The popularity within a week was significantly higher for acts resulting from patients' dissatisfaction with treatments than for acts resulting from nontherapeutic incidents.

Elaboración de un cuestionario de detección de casos de violencia de odio en urgencias hospitalarias / Preparation of a questionnaire to detect cases of hate violence in emergency rooms

OBJETIVO: En el marco del proyecto SIVIVO se propuso la elaboración de una herramienta que facilitase la detección, el registro y la descripción de casos de violencia de odio y sus consecuencias sobre la salud. MÉTODO: Se utilizó el método Delphi a dos vueltas con personas expertas pertenecientes a los ámbitos clínico-asistencial, salud pública, investigación epidemiológica, académico, administración y organizaciones no gubernamentales para evaluar la pertinencia de diferentes ítems mediante una escala Likert de 1 a 5, y los resultados se presentan como medianas y coeficientes de variación. RESULTADOS: Las preguntas mejor valoradas, con puntaciones ≥4, y que componen la versión final del cuestionario, son las relativas a las características sociodemográficas de la víctima, el tipo de lesiones, la descripción del incidente, las motivaciones percibidas por la persona agredida, posibles evidencias de odio, la intención de denunciar y la percepción del personal sanitario del motivo de la agresión. El pilotaje mostró la adecuación de las preguntas finalmente seleccionadas. CONCLUSIONES: La incorporación sistemática de esta herramienta puede ayudar a conocer la magnitud y las características de la violencia de odio y su repercusión en la salud. Esta información permitiría elaborar estrategias de prevención e intervención dirigidas, especialmente, a los sectores de población más expuestos a este tipo de violencia

OBJECTIVE: In the context of the SIVIVO project, the development of a tool to facilitate the detection, recording and description of cases of hate violence and its consequences on health was proposed. METHOD: A two-round Delphi method was used with experts from clinical-care, public health, epidemiological, academic, administration and non-governmental organizations to assess the relevance of different items using a Likert scale, presenting the results with medians and coefficients of variation. RESULTS: The best evaluated questions, with scores equal to or greater than 4, and which make up the final version of the questionnaire are the relative socio-demographic characteristics of the victim, the injuries, description of the incident, the motivations perceived by the aggrieved person, possible evidence of hatred, the intention to denounce and the perception of the health personnel of the motive for the aggression. The piloting showed the adequacy of the questions that were finally selected. CONCLUSIONS: The systematic incorporation of this tool can help us to learn the magnitude and characteristics of hate violence and its impact on health. This information would allow the elaboration of prevention and intervention strategies aimed, specifically, at the sectors of the population most exposed to this type of violence

[Interpersonal violence in Spain through national hospital discharge survey]. / La violencia interpersonal en España a través del Conjunto Mínimo Básico de Datos.

OBJECTIVE: To describe the epidemiology of interpersonal violence in Spain. METHOD: Descriptive study of the cases of patients with secondary diagnosis of aggression registered on a national hospital discharge database, between 1999 and 2011, using the codes from E960 to E969 of the ICD-9. The distribution by sex, age and type of discharge, associated morbidity, mortality and by autonomous community is described. The quality of the record is studied according to its temporal variation. RESULTS: The case profile of aggression in men (85%) is of a patient between 15 and 44 years old, who in 93.7% of cases requires urgent care and whose severity is moderate (95% discharge home). Two point five percent of patients are readmitted and death occurs in1.1%. The profile in women (15%) differs slightly, with an age between 31 and 52 years, 94% require urgent attention, although 96% have moderate severity; 3% are readmitted and 1.7% die. CONCLUSIONS: Although they need to be improved to avoid certain limitations, health information systems are a rich source of data that can be used for research in health and, through their results, for the development of prevention plans and intervention in matters of violence.

Expressions of school violence in adolescence / Manifestaciones de violencia escolar en la adolescencia

BACKGROUND: Research on school violence, which disserves the quality of the process of teaching and learning in schools, has increased in recent decades. The aims of this study were to identify the most prevalent types of school violence in Compulsory Secondary Education (CSE) according to the opinion of students, and to analyse differences in gender, school year, and the academic performance of the student informants. METHOD: The CUVE3-CSE questionnaire was applied to 4,943 CSE students (average age: 14.04; SD: 1.38) who are studying at 33 public and private schools. RESULTS: showed the predominance of classroom disruption and student-to-student verbal violence, as well as differences in the level of perceived violence according to the variables analysed (gender, school year and academic performance). CONCLUSIONS: The study underscores the wide-ranging typology of violence at schools, and its everyday occurrence in classrooms, which highlight the need for improving our understanding in order to enhance the efficacy of prevention and intervention programs

ANTECEDENTES: en las últimas décadas se han incrementado las investigaciones sobre violencia escolar, la cual perjudica la calidad del proceso de enseñanza-aprendizaje en los centros educativos. Esta investigación tiene como objetivos identificar los tipos de violencia escolar más habituales en la Educación Secundaria Obligatoria (ESO) y analizar las diferencias por género, curso escolar y rendimiento académico del alumnado respecto a los tipos de violencia. MÉTODO: se aplicó el cuestionario CUVE3-ESO a 4.943 estudiantes (media de edad: 14,04; DT: 1,38) que cursan ESO en 33 centros públicos y concertados. RESULTADOS: muestran un predominio de la disrupción en el aula y la violencia verbal entre el alumnado, así como diferencias en el nivel percibido de violencia en función de las variables analizadas (género, expediente académico y curso escolar). CONCLUSIONES: el estudio deja entrever cómo la violencia en contextos escolares presenta una tipología amplia y variada, ejercida de forma cotidiana en las aulas, por lo cual se debe seguir profundizando en su conocimiento para acrecentar la eficacia de las medidas de prevención e intervención

Achieving just outcomes: forensic evidence collection in emergency department sexual assault cases.

BACKGROUND: Achieving just outcomes in sexual assault cases is one of the most serious and complex problems facing the healthcare and justice systems. This study was designed to determine the prevalence and correlates of Sexual Assault Evidence Kit (SAEK) completion and release to police among sexual assault cases presenting to the ED. METHODS: Data for this retrospective study come from the Sexual Assault and Partner Abuse Care Programme (SAPACP) case registry (1 January to 31 December, 2015) at The Ottawa Hospital, a unique medical-forensic access point and the only facility offering SAEK collection in Ottawa. Bivariable and multivariable logistic regression models were conducted using ORs, adjusted ORs (AORs) and 95% CIs. RESULTS: In 2015, 406 patients were seen by the SAPACP and 202 (77.1%) were eligible for a SAEK. Among eligible cases, 129 (63.9%) completed a SAEK and 60 (29.7%) released the SAEK to police for investigation. Youth cases (≤24 years) had the highest odds of completing a SAEK (AOR 2.23, 95% CI 1.18 to 4.23). Cases who were uncertain of the assailant (AOR 3.62, 95% CI 1.23 to 10.67) and assaults that occurred outdoors (AOR 3.14, 95% CI 1.08 to 9.09) were most likely to release the SAEK to police. CONCLUSION: Even with access to specialised forensic evidence collection, many sexual assault survivors do not complete a SAEK, and even fewer release the evidence to police for investigation. The ED is a common entry points into the healthcare system, and this study has highlighted the need to strengthen services and reduce attrition along the health-justice continuum.

Levels of combatant control and the patterns of non-incumbent/insurgent violence experienced by civilians living in Sunni-Arab communities in Iraq (2004-2009).

This study explores how one social-structural variable, control over Sunni-Arab communities during the Iraq civil war, affected the types of violence used by insurgent/non-government actors that killed and injured civilians in these communities from January 2004 to December 2009. The study classifies three levels of control: (1) incumbent (government-supported) control, (2) insurgent control and (3) actively contested control. It uses Iraq Body Count (IBC) fatality data to characterize two general types of violence (selective and indiscriminate) evident during the Iraq conflict. It demonstrates that the type of violence committed by non-government actors was significantly (P > .01) different as related to the level of control insurgents had over territory. Primarily, insurgents/non-governmental actors used more selective forms of violence when insurgents controlled territory and more indiscriminate violence when incumbent (government-supported) forces controlled territory. Also, acts of indiscriminate violence cause considerably more injuries and death per act as compared to selective violence. Importantly, if control over territory has broadly generalizable effects on the types of violence that civilian's experience during civil war, than understanding this relationship could be useful when determining the types of medical assistance, medical supplies and training most needed in combat zones.

Fight Recognition in video using Hough Forests and 2D Convolutional Neural Network.

While action recognition has become an important line of research in computer vision, the recognition of particular events such as aggressive behaviors, or fights, has been relatively less studied. These tasks may be extremely useful in several video surveillance scenarios such as psychiatric wards, prisons or even in personal camera smartphones. Their potential usability has led to a surge of interest in developing fight or violence detectors. One of the key aspects in this case is efficiency, that is, these methods should be computationally fast. "Handcrafted" spatiotemporal features that account for both motion and appearance information can achieve high accuracy rates, albeit the computational cost of extracting some of those features is still prohibitive for practical applications. The deep learning paradigm has been recently applied for the first time to this task too, in the form of a 3D Convolutional Neural Network that processes the whole video sequence as input. However, results in human perception of other's actions suggest that, in this specific task, motion features are crucial. This means that using the whole video as input may add both redundancy and noise in the learning process. In this work, we propose a hybrid "handcrafted/learned" feature framework which provides better accuracy than the previous feature learning method, with similar computational efficiency. The proposed method is compared to three related benchmark datasets. The method outperforms the different state-of-the-art methods in two of the three considered benchmark datasets.
