Next- generation wireless communications are projected to integrate reconfigurable intelligent surfaces (RISs) to perpetrate enhanced spectral and energy efficiencies. To quantify the performance of RIS-aided wireless networks, the statistics of a single random variable plus the sum of double random variables becomes a core approach to reflect how communication links from RISs improve wireless-based systems versus direct ones. With this in mind, the work applies the statistics of a single random variable plus the sum of double random variables in the secure performance of RIS-based non-orthogonal multi-access (NOMA) systems with the presence of untrusted users. We propose a new communication strategy by jointly considering NOMA encoding and RIS’s phase shift design to enhance the communication of legitimate nodes while degrading the channel capacity of untrusted elements but with sufficient power resources for signal recovery. Following that, we analyze and derive the closed-form expressions of the secrecy effective capacity (SEC) and secrecy outage probability (SOP). All analyses are supported by extensive Monte Carlo simulation outcomes, which facilitate an understanding of system communication behavior, such as the transmit signal-to-noise ratio, the number of RIS elements, the power allocation coefficients, the target data rate of the communication channels, and secure data rate. Finally, the results demonstrate that our proposed communication can be improved significantly with an increase in the number of RIS elements, irrespective of the presence of untrusted proximate or distant users.

Jack the Ripper fictions tend to be realist in mode, making frequent use of the Victorian press and archives to depict the 1888 murders. At the same time, they marginalise and exploit the victims, defining them as silent testimonies to the power of the elusive perpetrator. In contrast, Alan M. Clark’s Jack the Ripper Victims Series (2011–2018), consisting of five novels devoted to one canonical victim each, shifts the focus and depicts their lives. This article outlines the way the fictionalisations of the five women’s lives bring to the fore five other ‘crimes’ or transgressions: addiction, domestic violence, unemployment, sex work, and homelessness, but also the way these texts replace what is sensational and formulaic in Ripperature with something more than mundane and gritty in the lived experience of everyday people, such as moments of personal joy or professional accomplishments. Drawing on Kate Mitchell’s approach to history, cultural memory, and neo-Victorian fiction, it argues that pre-dating the publication of The Five (2019), Clark managed to realistically re-present (make present) and represent (create a portrayal of) the late-Victorian crime of dismissing the women who were murdered.

The present questionnaire study explores the relationship between intimate partner violence (IPV), coping strategies, and psychological maladjustment for both female and male college students, as well as considering the effects of perpetrated IPV. College students are at risk for experiencing and perpetrating IPV, and coping skills may act as important risk and protective factors. In total, 333 (247 women, 86 men) undergraduate college students completed an online survey for research participation credit. Perpetrated intimate partner verbal aggression and experienced and perpetrated relationship violence were significantly correlated with somatization and depression, while for women, perpetrated verbal aggression was significantly correlated with somatization, depression, anxiety, and eating disorder symptoms. Experienced verbal aggression was significantly correlated with depression for women, while perpetrated verbal aggression was significantly correlated with anxiety for men. Path analyses with bootstrapped mediation tests found that, for men, the relationships between experienced violence and somatization and depression were significantly mediated by avoidant coping, while for women, the relationships between perpetrated verbal aggression and somatization, depression, anxiety, and eating disorder symptoms were significantly mediated by avoidant coping. Findings suggest that, particularly for women, the use of avoidant coping behaviors may exacerbate cycles of victimization by and perpetration of IPV that, in turn, lead to greater psychological distress. The present findings suggest that interventions to reduce IPV should put greater emphasis on the teaching of adaptive coping skills in couple relationships to help reduce the impulse to perpetrate violence, on top of coping skills to deal with experienced violence.

Cyberbullying entails multiple, problematic consequences for its victims. However, little is known about the factors that influence the dispersion of these damaging messages. Drawing on theories of social interaction, we argue that perpetrators disseminate messages containing sexist and racist slurs that reinforce stereotypical, social norms to enhance their online visibility. We collected cross-sectional and longitudinal samples of tweets (N = 539,558 and 248,497, respectively) that included either gender or Asian slurs. We find that tweets containing gender or Asian slurs that were more negative in sentiment had a significantly higher number of retweets than more positive tweets, thereby heightening a user’s online presence and the reach of their content. Two historical events unfolded during our study—the onset of COVID-19 and the murder of George Floyd by a police officer. Tweet negativity increased following both events. Our findings demonstrate the capacity of aggressive tweets to generate wide-ranging networks, a process which is exacerbated further by public crises. Results suggest that the practice of sending such messages is strategic. Perpetrators likely engage in cyberbullying, consciously or not, to increase their online attention. Moreover, this strategy appears to be successful. Full article

Background: Gender-based violence (GBV) is one of the most pronounced expressions of the unequal power relations between women and men. As a tool for action against this phenomenon, psychological intervention programs for perpetrators of GVB are offered. This is how reGENER@r was born; it is a two-month program based on psychoeducational and cognitive-behavioral strategies that is part of the alternative measures to GBV-related prison sentences. The purpose of this study is to assess the efficacy of the reGENER@r program on the variables of emotional intelligence, empathy, coping responses, emotional dependency, gender role conflict, and sexist beliefs. Method: To this end, a sample of 37 subjects convicted of crimes of GBV was collected, and a pre- and post-evaluation by means of self-report was carried out. Changes were examined for statistical significance and clinical significance. Results: Significant improvements were observed in the variables of cognitive avoidance, emotional attention, hostile sexism, and distorted thoughts about women and the use of violence. Conclusions: Limitations and implications of these findings are discussed, and some modifications are suggested such as making interventions longer, with a greater gender focus, adapted to the individual characteristics of the participants, and complemented with individual sessions.

Child maltreatment is a worldwide issue with serious consequences throughout life. Maltreated children tend to be at greater risk of developing aggressive and antisocial behaviours (e.g., violent behaviour in adulthood). The present study aims to analyse how temperament mediates the relationship between childhood trauma and sexual violence perpetration in adolescence. The present cross-sectional study was conducted with 252 Portuguese adolescent students between ages 11 and 20 years (n = 126 boys), of whom 126 self-identified as perpetrators of sexual violence. Overall, the results show that temperament mediated the relationship between emotional abuse and the perpetration of sexual violence. Limitations and implications for future studies were discussed. This study will be crucial for the development of intervention programs on violence and will help to explore these practices in intimate relationships. A better understanding of violence through the identification of variables of interest will allow a better understanding of this phenomenon, deepening the relational dynamics between the different genders.

Objectives: to examine the nature and context of discriminatory experiences among adolescents in Spain. Methods: A mixed study of discourse content analysis in 1000 randomly selected Spanish adolescents aged 12 to 16 years stratified by age, gender and territorial distribution. Data were analyzed to identify perpetrators, actions, and locations of discrimination. Results: Overall, 66% of adolescents reported witnessing or experiencing discrimination, primarily manifested through teasing, insults, and harassment. Peers were identified as the main perpetrators (73.9%), with schools being the primary context (69.4%) where discrimination occurs. Discrimination often lacked clear reasons (27.78%), but ethnicity (23.83%) and physical appearance (22.51%) were the most common factors, followed by gender (5.99%) or academic/ability issues (5.99%) or having an illness or developmental disorder (5.41%). Conclusions: Discrimination among adolescents is frequent, with racism and rejection of minority groups as the main causes. The findings underscore the need for interventions to address discriminatory behaviors in schools and broader society, with implications for adolescent well-being and mental health. Full article

In the wake of the advancements made in civil and human rights in the twentieth century, social movements have come to be regarded as a driving force behind social change. Nevertheless, evidence demonstrates that social transformations driven by certain citizen mobilisations do not always prove beneficial to the most marginalised groups. In January 2023, acts of vandalism were perpetrated against the buildings of public institutions in Brasilia. Similarly, anti-democratic mobilisations have been observed in Colombia against the peace agreement with the FARC and in Chile against the proposed more inclusive constitution. Globally, anti-democracy and other movements that are in opposition to human rights are gaining ground, and their effects are having a detrimental impact on the environment in which organisations that are advocating for excluded sectors are operating. However, Latin American perspectives of social and behaviour change (SBC) emphasise engagement with social movements to contribute to social justice, creating alliances to amplify the voices of those most affected without interfering with the organic nature of citizen-led movements. This prompts the following inquiries: Can we categorize as social movements those with popular roots but espousing hegemonic interests? How can the Latin American tradition of social movement action and reflection inform strategies for social change? How can SBC strategies counteract anti-human rights movements and empower social movements prone to inclusion? This essay addresses these questions. Full article

Over the years, there has been increasing interest in violence against women and its significant effects on victims. However, there has been comparatively little interest regarding violence against men and its effects within the workplace. This is despite the fact that scholarly research has highlighted the frequency of this phenomenon, further exacerbated by the poor functioning of support services, which intensifies distress among male victims. The present review focused on examining publications indexed in bibliographic databases (Scopus, PubMed, and Web of Science) from the years 2012–2023 to comprehend the contemporary landscape of academic literature concerning violence against men, along with its implications within the workplace. A total of 20 studies met inclusion criteria, and all selected papers focused on male victims of violence were included in this review. The results highlight the significant presence of male victims within the context of gender-based violence and harassment, domestic violence, and intimate partner violence. This literature review additionally highlights that social representation and gender stereotypes seem to contribute to the low demand for intervention by victims and the imbalance in their effects on the public and practitioners. Moreover, the results underscore the intricate and profound repercussions of violence against men within the workplace. This review, offering an overview of existing research in this field, emphasizes the necessity for future research to enhance understanding of quantitative methodologies and to facilitate specialized training for practitioners. Hence, it becomes imperative to actively identify interventions tailored to safeguarding the well-being of male victims of violence. Full article

This study examined the effectiveness of the virtual delivery of the Strength at Home (SAH) intervention program for intimate partner violence in a sample of 605 military veterans across 69 Veterans Affairs (VA) Medical Centers through a national implementation of the program. Outcome measures included physical IPV, psychological IPV, coercive control behaviors, post-traumatic stress disorder (PTSD) symptoms, and alcohol misuse. Significant pre-intervention to post-intervention reductions were found for all the outcomes, with similar effect size estimates relative to a prior investigation of in-person-delivered SAH through the same national VA implementation. Study findings suggest that the virtual delivery of SAH may be as effective as in-person delivery which has important implications for program access and impact. Full article

Beliefs that uphold patriarchal principles may influence individuals’ willingness to avoid conflict in their intimate-partner relationships, which can, in turn, increase the likelihood of intimate-partner economic violence. However, these associations remain underexplored in current research. This study examines these dynamics within a sample of 321 adults from the Ultra-Orthodox Jewish community—a patriarchal and traditional culture. Specifically, it examines associations among beliefs supporting patriarchal principles at the micro (gendered domestic roles), meso, and macro (institutional power of men and the inherent inferiority of women) levels; conflict avoidance; economic violence; and sex differences in these factors. Descriptive statistics were used to analyze sex differences in the study variables, and path analysis was used to examine the correlations between research variables for men and women. The findings indicate that beliefs in patriarchal ideologies were moderate across all levels but slightly higher among men. Men were significantly more likely than women to avoid conflict with their intimate partners. Beliefs in support of patriarchal ideologies were predictive of conflict avoidance, particularly among women. Contrary to prior research, this study revealed nonsignificant sex differences in the prevalence of economic-violence victimization. These findings, however, do not negate the role of sex-based dynamics in economic-violence victimization. We discuss the findings and the meanings assigned to conflict avoidance by men and women, while considering gender disparities of power and control. We suggest that men’s tendency to avoid conflict likely moderated their likelihood of perpetrating economic violence. Full article

In Rwanda, following the 1994 Genocide against the Tutsi, many people were found guilty of genocide crimes and imprisoned. Their children ended up in a situation of ambiguous loss during and after a parent’s imprisonment. The article presents the multidimensional impact of this loss on the everyday lives of these children and their families according to key themes as they emerged from an ethnographic study in which 21 children and their family members participated. Themes include changed family dynamics and family stress, economic deprivation, incomprehension of a parent’s criminal past, the social stigma of being a child of a génocidaire, and strategies used to make the loss bearable. The uniqueness of the ambiguous loss as experienced by children of perpetrators of genocide in Rwanda compared to those of perpetrators of the Holocaust or other mass crimes relates to an amalgam of factors specific for the context of post-genocide Rwanda; major ones being the severity of genocidal crimes and gacaca courts Rwanda chose as its main form of transitional justice. The case study illustrates how using the prism of intergenerational relations helps to understand some of the transformative and enduring effects of a crisis that deeply affects a society.

Gender-based violence (GBV) is an age-long issue plaguing societies all over the globe. Over the years, GBV perpetrated against women has been justified and legitimized by patriarchal and hegemonic masculine structures. This study explored the role of hegemonic masculinities and transnational cultural conflicts in creating a suitable environment for GBV against women newcomers from the continent of Africa. The study gathered perspectives of African immigrants and of the service providers working in immigrant-serving organizations. The paper adopts a qualitative approach and hinges on the transnationalism framework. This framework argues that immigrants maintain connections while transitioning to their destination countries. In such processes, immigrants carry with them their beliefs about cultural norms and hegemonic masculinity, of their country of origin. A total of 13 women immigrants and 20 service providers were purposively recruited to participate in the semi-structured interview. The interviews were recorded and transcribed verbatim. The data were analyzed thematically and organized using Nvivo version 12. Findings show that African immigrant women in Canada disproportionately bear the burden of GBV due to hegemonic masculinities. The construction of masculinity in immigrant populations is heavily reliant on the communities of origin. As such, the prevailing systems during and post migration such as—unstable residency status, fear of deportation, fear of social and family sanctions and stigmatization, economic dependence on their spouses, and fear of retaliation from their spouses creates an environment that supports toxic masculinity. The study recommends comprehensive and culturally sensitive programmes and services to support African immigrants affected by hegemonic masculinity and GBV. Full article

Gender-based violence is a public health issue influenced by culture and social values, which is why its comprehensive prevention requires addressing distorted beliefs and legitimising myths present in society. The aim of this study was, on the one hand, to design and validate the Gender-Based Violence Stereotypical Beliefs Scale (GBVSBS), and, on the other, to analyse the differences between men and women regarding these beliefs. The sample consisted of 404 university students from the Community of Madrid and Castilla-La Mancha (Spain), aged between 18 and 53 years. This study is based on a quantitative methodology and a cross-sectional design. The judgement of four specialists in the field supported the content validity of the items. Factorial analyses provided evidence for a two-factor model: myths about male perpetrators and myths about gender-based violence and female victims. The fit indices and reliability coefficients were adequate. Stereotypical beliefs about gender-based violence correlated with victim-blaming attitudes, and different levels of acceptance were found depending on gender. In conclusion, this study offers a valid and reliable instrument with which to analyse the sociocultural beliefs surrounding gender-based violence today, promoting the implementation of socio-educational interventions.

There is limited knowledge about time trends in cyberbullying involvement, and whereas previous studies have often focused on various mental health outcomes, possible outcomes of cyberbullying may concern a wide range of areas. A better understanding of cyberbullying development over time, as well as of the possible consequences, is needed for effective prevention and intervention efforts. The aims of this study were (i) to gain knowledge of time trends in cyberbullying among Norwegian adolescents, and (ii) to better understand how different forms of cyberbullying involvement is related to a variety of outcomes. Data from the Norwegian Ungdata surveys (2014–2016) were used to assess involvement in cyberbullying over time. Associations with cyberbullying involvement and four outcome variables (belief in a good and happy life, loneliness, school thriving, and depressive symptoms) were assessed using logistic regression analyses. Across years of study, the prevalence rates for cyberbullying involvement were 1.5% for perpetration, 3% for victimization, and 1% for perpetration-victimization. Compared with non-involvement, involvement in cyberbullying in any role was associated with poorer outcomes on all variables. Cyber-victims who were also perpetrators were less likely to have high levels of loneliness and depressive symptoms, compared to cyber-victims only. The prevalence of cyberbullying involvement among adolescents in Norway was relatively unchanged between 2014 and 2016. Cyberbullying involvement is associated with negative outcomes related to mental health, loneliness, school thriving, and beliefs in one’s personal future, and victims of cyberbullying appear to be the most vulnerable group.
