Preschool Aggression and Victimization: A Short-Term Longitudinal Analysis of the Immediate Social Environment.

Introduction: Preschool aggression, a significant concern, requires an in-depth examination beyond individual factors. This study explored the link between individual characteristics, immediate social environment variables, and the likelihood of preschoolers being nominated as aggressors or victims. The novelty of the study lies in its comprehensive longitudinal examination, using a multi-informant approach, of how family dynamics, peer relations, teacher-child interactions, and community factors are related to preschool aggression within the context of Bronfenbrenner's ecological system theory. Methods: Data was collected at two points, four months apart, to investigate the interplay among sociodemographic, individual, family, and school factors and subsequent child aggression. The study included 394 children (184 girls, 210 boys), aged 3 to 6 years (M = 4.36, SD = 0.87). Caregivers completed questionnaires on socioeconomic status, community relationships, children's emotional regulation, and family functioning. Teachers rated closeness with each child, while children nominated liked and disliked peers, as well as those exhibiting aggressive or victimized behaviour. Results: Logistic regression models revealed stronger associations between peer aggression and victimization and individual factors over microsystems. Surprisingly, community cohesion showed a robust positive link with an increased likelihood of children being nominated as victims, challenging the assumption that positive parenting practices and strong community cohesion always leads to positive outcomes for individuals. Discussion: The study advances theoretical understanding by examining how factors within preschoolers' microsystems influence aggressive behaviors, contributing to more holistic models for addressing preschool aggression and victimization in schools. The findings highlight the significance of targeted interventions, emphasizing early identification of aggression or victimization signs and customized programs for social and emotional skill development. Addressing parental stress and interparental conflict is crucial. Additionally, community-based initiatives, like strengthening support networks, play a pivotal role in fostering healthier social dynamics among preschoolers.

Attachment insecurity and breadcrumbing engagement in young adults: a cross-sectional, cross-country study in India and Spain.

BACKGROUND: Breadcrumbing, defined as the act of sending out flirtatious, but non-committal text messages to lure a sexual/romantic partner without expending much effort, has gained attention in popular culture and the media due to its relevance to contemporary dating dynamics. However, there is lack of evidence of the association between attachment insecurity and breadcrumbing This study aims to uncover the potential relationship between breadcrumbing engagement and attachment insecurity among Indian and Spanish young adults. METHODS: Data were collected through an anonymous online survey answered by 334 adults in India and by 348 adults in Spain aged between 18 and 40 years old. A linear regression model in both countries was run to examine breadcrumbing engagement and its relationship with the set of sociodemographic variables included in the study (participants' age and sex, sexual orientation, relationship status and educational level) and the two dimensions of attachment insecurity (anxious and avoidant). RESULTS: The results showed that insecure attachment, both anxious and avoidant, were associated with engaging in breadcrumbing in both the countries. However, there was a stronger association between anxious attachment and breadcrumbing in India compared to Spain, where the association was stronger between avoidant attachment and breadcrumbing. CONCLUSIONS: Findings from this study offer insight into an under-studied practice in the context of interpersonal relationships (i.e., breadcrumbing behaviour) and show the importance of attachment theoretical framework to hypothesize and analyse expectations regarding strategies to negotiate intimate relationships and the breadcrumbing experience particularly.

New insights in the Spanish gene pool of olive (Olea europaea L.) preserved ex situ and in situ based on high-throughput molecular markers.

In Spain, several local studies have highlighted the likely presence of unknown olive cultivars distinct from the approximately 260 ones previously described in the literature. Furthermore, recent advancements in identification techniques have significantly enhanced in terms of efficacy and precision. This scenario motivated a new nationwide prospecting effort aimed at recovering and characterizing new cultivated germplasm using high-throughput molecular markers. In the present study, the use of 96 EST-SNP markers allowed the identification of a considerable amount of new material (173 new genotypes) coming from areas with low intensification of production in different regions of Spain. As a result, the number of distinct national genotypes documented in the World Olive Germplasm Bank of IFAPA, Córdoba (WOGBC-ESP046) increased to 427. Likewise, 65 and 24 new synonymy and homonymy cases were identified, respectively. This rise in the number of different national cultivars allowed to deepen the knowledge about the underlying genetic structure. The great genetic variability of Spanish germplasm was confirmed, and a new hot spot of diversity was identified in the northern regions of La Rioja and Aragon. Analysis of the genetic structure showed a clear separation between the germplasm of southern and northern-northeastern Spain and indicated a significantly higher level of admixture in the latter. Given the expansion of modern olive cultivation with only a few cultivars, this cryptic germplasm is in great danger of disappearing. This underlines the fact that maintaining as many cultivars as possible will increase the genetic variability of the olive gene pool to meet the future challenges of olive cultivation.

Families, Parenting and Aggressive Preschoolers: A Scoping Review of Studies Examining Family Variables Related to Preschool Aggression.

BACKGROUND: A growing body of research has shown that children behave aggressively from an early age. In recent decades, such behaviour has become a focus of scientific interest, not only because of the adverse consequences of these interactions, but also because high levels of aggression, especially at an early age, may be a risk factor for the use of other forms of aggression, such as bullying, later on during their development. These behaviours are related not only to individual characteristics, but also to peer relationships, teacher behaviours, school variables, family factors and cultural influences. METHOD: In order to find out which family variables have been researched in relation to preschool aggression and which family variables are associated with perpetration and victimisation, a scoping review was conducted in accordance with the PRISMA guidelines. Four databases (Web of Science, Scopus, PubMed and PsycINFO) were used to map the studies published between 2000 and 2022. RESULTS: This scoping review included 39 peer-reviewed articles from an initial sample of 2002 of them. The majority of studies looked only at perpetration behaviours. The main family variables covered in the articles concern parental behaviours, adverse childhood experiences in the family environment, and the household structural and sociodemographic characteristics. CONCLUSION: This scoping review shows that different factors within the family environment increase the risk of developing aggressive and victimising behaviours in the preschool setting. However, the relationship between the family variables and preschool aggression is complex, and it may be mediated by other factors such as gender, child-teacher closeness or parent-child dyads.

Parenting Styles and Self-Esteem in Adolescent Cybervictims and Cyberaggressors: Self-Esteem as a Mediator Variable.

BACKGROUND: Family relationships and self-esteem are relevant variables into the understanding of cyberbullying. However, little is known about the mediating role of self-esteem in the connections between cyberbullying and parenting. The study had two goals: (1) to analyze the relation between being a cybervictim and/or cyberaggressor and self-esteem, parents' acceptance/coercion, and parenting styles and (2) to explore whether self-esteem is a mediator in the relationship between parents' acceptance/coercion and being a cybervictim/cyberaggressor. METHOD: The sample comprises 3026 Spanish adolescents (51.5% girls and 48.5% boys) aged 12-18 years (Mage = 14.39; SD = 1.69). The study has a cross-sectional design, retrospective ex-post with multiple measurements. RESULTS: (1) cybervictims and cyberaggressors have low self-esteem, and their parents have a low level of involvement/acceptance and a high level of coercion/imposition towards their sons/daughters, (2) participants whose parents were authoritarian obtained significantly lower scores in self-esteem and higher scores in cybervictimization/cyberaggression, whereas those whose parents were indulgent obtained significantly higher scores in self-esteem and lower scores in cybervictimization/cyberaggression, and (3) it was found a mediation of self-esteem in the relationship between the involvement/acceptance of both parents and being a cybervictim, as well as between the father's coercion/imposition and being a cyberaggressor. CONCLUSION: An adequate level of self-esteem, high parental acceptance/involvement, and a reasonably low level of coercion/discipline as the parenting style can have very positive effects on the prevention of cyberbullying.

Associations between Adverse Childhood Experiences within the Family Context and In-Person and Online Dating Violence in Adulthood: A Scoping Review.

Background: Adverse childhood experiences (ACEs) are a common pathway to risky behaviour, violence or re-victimisation, disability, illness, and premature mortality and, as such, may be associated with victimisation and perpetration of dating violence not only in adolescence but also in adulthood. Method: A scoping review was performed in accordance with PRISMA guidelines. Four databases (Web of Science, Scopus, PubMed, and PsycINFO) were used to search for studies published between 2000 and 2021 that analysed the relationship between adverse childhood experiences within the family context and the perpetration or victimisation of dating violence in adulthood. Results: The search yielded 599 articles, 32 of which met the inclusion criteria and were ultimately included in the review. Most of the study samples were from the United States. Most of the studies sampled university populations. The studies had a clear objective, were of an appropriate design, contained a detailed description of the sample, and used valid and reliable measurement instruments. Conclusion: This scoping review shows that the relationship between ACEs and perpetration and/or subsequent victimisation is complex and that, while adverse childhood experiences are a factor associated with adult dating violence, they are likely to coexist with other personal, family, and environmental problems. Therefore, adverse childhood experiences may not be a necessary or sufficient condition for experiencing dating violence.

Decarboxylative Allylic Alkylation of Phthalides: Stabilized Benzylic Nucleophiles for sp3-sp3 Coupling.

A new family of stabilized benzylic nucleophiles for the palladium-catalyzed decarboxylative allylic alkylation reaction has been developed. Allyl esters derived from 3-carboxyphthalides were found to undergo palladium-catalyzed deallylation and decarboxylation under mild reaction conditions, a process facilitated by the formation of a stabilized aromatic anion. The regioselective allylic coupling of this intermediate afforded a variety of functionalized phthalides in 73-96% yields.

Enantioselective Synthesis of (-)-10-Hydroxyacutuminine.

An enantioselective synthesis of (-)-10-hydroxyacutuminine is reported. Central to our strategy is a photochemical [2+2] cycloaddition that forges two of the quaternary stereocenters present in the acutumine alkaloids. A subsequent retro-aldol/Dieckmann sequence furnishes the spirocyclic cyclopentenone. Efforts to chlorinate the acutumine scaffold at C10 under heterolytic or radical deoxychlorination conditions led to the synthesis of an unexpected cyclopropane-containing pentacycle.

Bullying/Cyberbullying en Quinto y Sexto Curso de Educación Primaria: Diferencias entre Contextos Rurales y Urbanos / Bullying/cyberbullying in 5th and 6th year of primary education: Differences between rural and urban areas

El objetivo del estudio ha sido analizar las diferencias de bullying (tradicional y cyberbullying) en contextos rurales y urbanos. Ha participado un total de 2,162 estudiantes de 5º (52.7%) y 6º (47.3%) de Educación Primaria, un 49.3% en contexto urbano y 50.7% en contexto rural. Los resultados indican un porcentaje de intervención similar en colegios de contexto urbano y de contexto rural. Sin embargo, en los colegios rurales se ha encontrado una mayor prevalencia de víctimas de bullying verbal, exclusión y cyberbullying, mientras que en los colegios urbanos hay más alumnos que son agresores de bullying verbal y exclusión. En los colegios rurales la agresión va más dirigida a los compañeros del colegio, mientras que en los colegios urbanos se dirige hacia gente de fuera del colegio. Estos resultados indican que el tamaño de la población en la que se ubican las escuelas puede ser un factor relevante para la intervención.

The aim of this study is to analyse the differences between bullying and cyberbullying in rural and urban areas. The number of students who have participated in this research is 2,162: 52.7% in their 5th year of Primary Education in Spain (ages 10-11) and 47.3 % in their 6th year (ages 11-12) – 50.7% of them were living in the countryside and 49.3% in the city. Although the results showed that the impact of bullying/cyberbullying in rural and urban schools is very similar, some distinctive features have been identified: for example, in rural schools there are more victims of verbal bullying, exclusion, and cyberbullying, whereas in urban schools there is a clear trend of verbal bullying and exclusion. Depending on the context, there is also a significant pattern regarding the victims: in rural schools, victims of this type of abuse are schoolmates, but in urban schools victims and aggressors do not go to the same school. The results also show that the impact of this abuse depends on the size of the city/town where schools are located.

Relationship between Socio-Emotional Competencies and the Overlap of Bullying and Cyberbullying Behaviors in Primary School Students.

Digital life forms part of daily reality for young people. For this reason, traditional bullying in school has been reproduced in the online environment, resulting in an overlap of off- and online bullying. Research on socio-emotional competencies and bullying is revealing interesting results among students in secondary schools. However, studies involving primary school students are much scarcer. In addition, the majority of studies have been carried out based on an understanding of socio-emotional competencies as a unidimensional construct. In the present study, we examined the overlap between off- and online bullying victimization and the influence of the factors comprising socio-emotional competencies on this overlap. Participants comprised 1130 students (49.7% were boys and 50.3% were girls) from the fifth and sixth grades at 15 schools in the autonomous communities of Madrid and Castilla-La Mancha (Spain). The results indicate a high rate of overlap between off- and online bullying victimization, without significant gender differences. Poor relationship skills in boys and low self-management in girls were associated with being a victim of both traditional bullying and cyberbullying. The conclusions point to an interesting line of intervention and prevention, establishing a framework of confluence for social and emotional variables within the primary education context.

The Role of Social-Interpersonal and Cognitive-Individual Factors in Cyber Dating Victimization and Perpetration: Comparing the Direct, Control, and Combined Forms of Abuse.

The present study examined the relationship linking social-interpersonal factors (interpersonal dependency, social support, social skills), cognitive-individual factors (planning behavior and goal efficacy), and different victimization and perpetration forms of cyber dating abuse (direct abuse, control abuse, and the combination of both abuse types). The responses of 1,657 Spanish university students were analyzed (62.1% females, 37.1% males). The multinomial logistic regression model revealed similarities among the three victim groups and revealed that anxious attachment and lack of social support increased the likelihood of direct victimization, control victimization, and direct/control victimization. Differences were found in the three victim groups for social skills and planning behavior. Perpetration was significantly associated with anxious attachment in the three cyber dating perpetration forms. Differences were also found in emotional dependency, social support, and social skills among direct perpetrators, control perpetrators, and direct/control perpetrators. The results revealed that interpersonal and cognitive factors correlated with cyber dating victimization and perpetration.

A multicenter, observational study of pain and functional impairment in individuals with major depressive disorder in partial remission: the DESIRE study.

BACKGROUND: The study explores the association between pain and functional impairment in patients with partially remitted MDD, considering both clinician and patient reported outcomes. METHODS: Multicenter, observational, and cross-sectional study, with 583 outpatients with partially remitted MDD. Measures of pain intensity (VAS), functional impairment (SOFAS), depressive symptomatology (HAM-D6), and remission from MDD and functional status from a patient-centered perspective (RDQ) were collected. VAS scores (cut-off: 30) were used to divide the sample in two groups: no pain (n = 274) and pain (n = 309). Descriptive data, correlation and regression analyses were obtained. RESULTS: Functional impairment (SOFAS) and pain (VAS) were negatively and significantly correlated in the total sample, and in the group with pain. Lower pain predicted higher functioning. The pain sub-sample was older, less educated, with higher medical comorbidities, higher HAM-D6 scores, and lower functionality (SOFAS). In the RDQ, the pain group showed significantly higher scores in the symptom-related subscales, and lower scores in the subscales related to positive mental health, functioning and wellbeing. LIMITATIONS: Correlational and observational design. The criteria and instruments used to measure pain and to define a threshold might limit the generalizability of findings. CONCLUSIONS: Pain and functionality should be assessed and treated in patients with MDD in partial remission. Our results indicate that functionality should be assessed with a broader perspective, that also considers positive mental health features.

Adsorbate Isotherm Analysis by Reflection Anisotropy Spectroscopy on Copper (110) in Hydrochloric Acid.

Reflectance anisotropy spectroscopy (RAS) is a powerful optical probe that works on a polarization contrast basis. It can be operated in any environment, ranging from ultrahigh vacuum to vapor phases and liquids. The measured optical anisotropies are caused by several symmetry breaking effects and are exclusively assigned to the surface for otherwise bulk isotropic materials. In this work, we present a systematic study comprising in situ RAS-transient to assess the surface thermodynamics of the chloride adsorption on Cu(110) upon systematic variations of the applied electrode potentials in comparison to cyclic voltammetry (CV). Numerical time-derivatives of the measured RAS-transients are shown to be exclusively associated with electrical currents of those electrochemical reactions, which change the properties of the electrode surface. The recorded transient line-shapes track the Frumkin type isotherm properties related to chloride coverage. Both connections are theoretically discussed. Owing to the surface and interface specificity, RAS is shown to exhibit a high surface sensitivity. In particular, processes taking place in parallel, namely, the hydrogen evolution reaction (HER) as well as the copper dissolution as Cu+ and Cu2+, do not contribute to the RAS response.

Psychological Correlates of Ghosting and Breadcrumbing Experiences: A Preliminary Study among Adults.

The present study aimed to examine differences in three psychological constructs (satisfaction with life, loneliness, and helplessness) among adults experiencing ghosting and breadcrumbing. A sample of 626 adults (303 males and 323 females), aged from 18 to 40 years, completed an online survey asking to indicate whether someone they considered a dating partner had ghosted or breadcrumbed them in the last year and to complete three different scales regarding satisfaction with life, loneliness, and helplessness. The results showed than those participants who had indicated experiencing breadcrumbing or the combined forms (both breadcrumbing and ghosting) reported less satisfaction with life, and more helplessness and self-perceived loneliness. The results from the regression models showed that suffering breadcrumbing would significantly increase the likelihood of experiencing less satisfaction with life, and of having more feelings of loneliness and helplessness. However, no significant relation was found between ghosting and any of the examined psychological correlates.

Relations among Poly-Bullying Victimization, Subjective Well-Being and Resilience in a Sample of Late Adolescents.

: The present study examined the relations among poly-bullying victimization (experiencing multiple forms of peer bullying), resilience and subjective well-being. This study specifically examined late adolescents' resilience as a moderator of the relation between poly-bullying victimization and subjective well-being. In a region of central Spain, 1430 undergraduate students (64% females, 36% males), aged between 18 and 22 years, completed three self-reported measures, including bullying victimization experiences, self-reported subjective well-being and resilience. A substantial proportion of the participants (16.9%) reported being victims of poly-bullying. The results showed that the poly-bullying victimization group reported the poorest subjective well-being and the lowest resilience levels. The regression analyses revealed that resilience was significantly and positively associated with subjective well-being, and resilience moderated the association between poly-bullying victimization and subjective well-being. However, the relation was very weak and accounted for only an additional 1% of variance in the participants' subjective well-being. Future research should assess resilience trajectories of youth exposed to multiple forms of bullying victimization in order to better understand the potential protective effect of resilience over negative mental health outcomes.

Abuso online en el noviazgo y su relación con el abuso del móvil, la aceptación de la violencia y los mitos sobre el amor / Cyber dating abuse and its association with mobile abuse, acceptance of violence and myths of love

Resumen El presente estudio tiene como objetivo analizar la prevalencia y las diferencias en la frecuencia y cronicidad del abuso online en el noviazgo de acuerdo con distintas variables sociodemográficas. Además, se analiza su relación con los mitos del amor romántico, el abuso del móvil y la aceptación de la violencia. Usando una muestra de 1657 estudiantes universitarios, los resultados revelaron que el 43.3% de los encuestados fueron perpetradores y el 42% víctimas de al menos un comportamiento de abuso online en el noviazgo durante los últimos doce meses. Se encontraron diferencias significativas en el abuso online de acuerdo con el sexo, la edad, la orientación sexual, ingresos medios anuales familiares y el nivel educativo de los padres. Final mente, los resultados revelaron una relación significativa entre el abuso online en el noviazgo con el abuso del móvil, los mitos del amor romántico, y la aceptación de la violencia.

Abstract The present study aimed to analyze the prevalence, and the differences in the fre quency and chronicity of cyber dating abuse according to different sociodemographic variables. Additionally, the relationship of cyber dating abuse with the myths of romantic love, mobile abuse and acceptance of violence was analyzed. Using a sample of 1,657 university students, the results revealed that 43.3% of the respondents were perpetrators and 42% were victims of at least one behavior of dating online abuse during the last 12 months. Significant differences were found in cyber dating abuse according to sex, age, sexual orientation, family income and parent's educational level. Finally, the results revealed a significant relationship between cy ber dating abuse, mobile abuse, the myths of romantic love, and the acceptance of violence.

Associations between Feminine Gender Norms and Cyber Dating Abuse in Female Adults.

Gender norms and the co-occurrence of perpetration and victimization behaviors have been examined as key factors of female dating violence in offline contexts. However, these relationships have not been analyzed in digital environments. This is why the present study had a twofold objective: (1) exploring the co-occurrence nature of cyber dating abuse by examining to what extent victimization and perpetration overlap; (2) examining the associations between conformity to feminine gender norms and cyber dating abuse among female adults who are perpetrators or victims. The sample study included 1041 female university students (mean age = 20.51) from central Spain. The results indicated that 35.8% of the sample reported being a victim and a perpetrator of cyber dating abuse at the same time. Indeed, the hierarchical regression analyses revealed a close association between perpetration and victimization behaviors in both the direct and control forms of abuse examined. Our analyses did not reveal any significant associations between conformity to female gender norms and perpetration or victimization for any cyber dating abuse form examined. Our results are discussed in the light of previous research and after considering limitations, practical implications and future research directions.

Effectiveness of low-frequency electrical stimulation in proprioceptive neuromuscular facilitation techniques in healthy males: a randomized controlled trial.

BACKGROUND: Hamstring muscle injuries are common in the sports field, with lack of hamstring flexibility being a risk factor. Stretching the hamstring muscles is an important part of the training and rehabilitation programs used to prevent or treat injury and improve performance. We aim to compare the immediate and follow-up effect on hamstring muscle flexibility between 2 different stretching protocols, proprioceptive neuromuscular facilitation (PNF) stretching and PNF stretching combined with electrostimulation. A second aim is to determine whether physical activity level is related to flexibility. METHODS: Design of study: Single-blind, randomized controlled trial; Participants: 30 healthy volunteers (30 men, 18-39 years old); Intervention: A 6-session intervention program spanning over 2 weeks and 1-week and 3-week follow-up. The control group underwent PNF stretching with a voluntary contraction. The experimental group underwent PNF stretching but the muscle contraction was triggered with an electrical stimulation device (TENS); Main outcome measu: Hamstring muscles flexibility was assessed using the Modified Sit and Reach (MSR) and the Back Saver Sit and Reach (BSSR) tests. Physical activity level was evaluated with the short form of the International Physical Activity Questionnaire (IPAQ). RESULTS: Both groups showed an overall increase in hamstring muscle flexibility. However, when comparing flexibility gain between baseline and the end of the stretching program (session 6), and at the 1-week and 3-week follow-ups, only the experimental group showed significant differences. No correlation between the IPAQ score and the degree of hamstring muscle flexibility was observed. CONCLUSIONS: Hamstring muscle PNF stretching combined with electrical stimulation to trigger muscle contraction during the muscle contraction phase of the stretch achieves better flexibility results when compared to PNF alone.

Health Contributing Factors in Higher Education Students: The Importance of Family and Friends.

The aim of this study was to determine well-being and its relationship to social support from friends and family communication in university students. A cross-sectional study was conducted with 1679 university students aged 18⁻25 years from four universities in Spain. Logistical regression models were tested (p < 0.05). The students in the last year of university reported higher well-being scores in comparison with students in the previous years. Well-being was inversely related to family communication problems. Family communication and social support from friends were the factors that associated the most with better well-being. All the regression models were statistically significant and explained from 16% of the well-being in Year 4 students until 34% of the well-being in Year 1 students. Our findings could be useful for developing interventions to promote health in order to improve college students' well-being. It is important for strategies to be developed in mental and family health areas.

Padres, hijos e internet. Socialización familiar de la red / Parents, Children and Internet Use. Family Socialization on the Internet

Resumen Estudios previos muestran resultados dispares en relación con la efectividad de la mediación parental en el uso de Internet. El objetivo fue analizar la influencia de los padres sobre el empleo de la red que llevan a cabo los hijos. Participaron en el estudio 938 familias con hijos entre 12 y 17 años. El análisis de regresión destaca la importancia del modelaje de los padres. Los resultados obtenidos muestran que la acción de los padres sobre el empleo de Internet de los hijos está mediada por el empleo que ellos mismos realizan de Internet. Este estudio apunta a la necesidad de que los padres se impliquen en los procesos de socialización sobre el uso de Internet.

Abstract Previous research has shown mixed results regarding the effectiveness of parental mediation in the Internet use. The main purpose of this study was to analyze the influence of parents on adolescent's Internet use. Sample consisted in 938 Spanish families with adolescents aged between 12-to-17 years old. Regression analysis confirmed the relationship between adolescents' Internet use and family variables, emphasizing the importance of modeling performed by parents. Specifically, results showed that the effect of parents' actions over their children's Internet use is mediated by the parent's use of the Internet. This study points out the need for parents to be involved in the socialization processes related with Internet use.
