RESUMEN

Background: This paper aims to examine the efficiency of Mexico's dairy farms within its four regions of Tlaxcala Stated. Methods: The Envelopment Data Analysis (DEA) applied to the variable returns to a scale model (VRS) for the year 2020. Also, Examine the statistical accuracy of efficiency estimation using bootstrap resampling techniques. The results reveal that Tlaxcala's dairy farm efficiency, on the other hand, was adversely influenced by three inputs (costs): cost of investment in livestock, the total annual cost for feeding, reproduction, diseases and treatments, preventive medicine, sanitation, milking, fuel, and total labor. Results: The efficiency distribution among farms using VRS, CRS, and FDH technologies reveals varying patterns. Under VRS and CRS, the majority of farms exhibit high efficiency within the 0 to less than 0.2 range, while FDH displays a broader distribution, with notable efficiency at 1 and across various ranges. These findings highlight the diverse landscape of efficiency levels across different technological approaches within the agricultural sector, offering valuable insights for optimization strategies and resource allocation. Conclusions: The utilization of Bootstrap methodology enhances the reliability of efficiency assessments by providing robust statistical techniques that accommodate non-normal data distributions. By incorporating Bootstrap, decision-makers can obtain more accurate estimates of efficiency levels and confidence intervals, thereby making informed decisions regarding resource allocation and optimization strategies within the agricultural sector. As part of the study, provided The Policy suggestions.

RESUMEN

OBJECTIVE: This pilot randomized controlled trial evaluated the effectiveness of critical time intervention-task shifting (CTI-TS) for people with psychosis in Santiago, Chile, and Rio de Janeiro. CTI-TS is a 9-month intervention involving peer support workers and is designed to maintain treatment effects up to 18 months. METHODS: A total of 110 people with psychosis were recruited when they enrolled in community mental health clinics (Santiago, N=60; Rio de Janeiro, N=50). Participants within each city were randomly assigned to either CTI-TS or usual care for 9 months. Primary outcomes were quality of life, measured with the World Health Organization Quality of Life Assessment-Brief Version (WHOQOL-BREF), and unmet needs, measured with the Camberwell Assessment of Need (CAN), at 18-month follow-up. Results were analyzed according to intention-to-treat guidelines. Generalized estimating equations, with observations clustered within cities, and multiple imputation for missing data were used. RESULTS: At 18 months, both groups showed improved primary outcomes. In both unadjusted and fully adjusted analyses, no significant differences between CTI-TS and usual care (WHOQOL-BREF question on quality of life and CAN mean number of unmet needs) were found. CONCLUSIONS: Three factors might explain the lack of difference between CTI-TS and usual care: first-contact enrollment precluded rapport prior to randomization, a minority of patients were uncomfortable with peers being on the treatment team, and primary outcome measures may not have been sensitive enough to capture the effects of a recovery-oriented intervention. The results have implications for the design of transitional services for people with psychosis, especially in Latin America.

RESUMEN

School engagement is considered a key variable in promoting educational trajectories. Previous research shows that maintaining high levels of school engagement is fundamental, given its association with multiple academic results and lower-risk behaviors. This article aims to show how school engagement profiles (based on the behavioral, affective, and cognitive subdimensions) relate to academic achievement (math and language), contextual factors (family, teachers, and peer support), and gender. This study involved 527 students enrolled in the 1st year of secondary education in public schools in Chile. All students came from vulnerable schools. Our study used cluster analysis to identify students' profiles. We identified the existence of three different profiles of school engagement (high, medium, and low) considering the three subdimensions of school engagement (behavioral, affective and cognitive). Secondly, ANOVA analysis showed differences in language and math academic achievement scores between the profiles, where higher engagement students showed higher academic performance in language and math. These findings are consistent with previous studies showing that contextual factors strongly influence school engagement and better behavioral engagement in female than male students. It will discuss the pertinence of person-centered approaches focusing on combinations of variables within students rather than taking each variable as the focal point when analyzing goals. These techniques are a favorable methodological alternative to investigate why some students have better results than others instead of just ranking students by their performance. It will conclude with some future lines of research and practical implications.

RESUMEN

Resumen Introducción: El consumo se ha instaurado como medio de interacción social generando altos niveles de endeudamiento en la población chilena. Los adolescentes han sido especialmente sensibles a esto, producto que a través del consumo acceden a elementos simbólicos asociados a la construcción de la identidad. El objetivo de la presente investigación es determinar la existencia de relaciones entre valores materiales, susceptibilidad al efecto de pares y actitudes hacia el dinero con respecto a las actitudes hacia el endeudamiento hedónico en estudiantes secundarios chilenos. Método: La muestra es de 1297 estudiantes secundarios chilenos, el 46% es hombre y el 54% es mujer, correspondientes a las ciudades de La Serena, Coquimbo, Santiago y Temuco. Se aplicaron las escalas de Actitudes hacia el Endeudamiento, Materialismo para Adolescentes, Escala de Susceptibilidad a la Influencia de los Pares y la Escala de Actitudes hacia el Dinero. Los datos fueron analizados a través de una regresión lineal múltiple jerárquica. Resultados: Se evidencian relaciones estadísticamente significativas entre sexo, valores materiales, susceptibilidad al efecto de pares y las actitudes hacia el dinero con respecto al endeudamiento hedónico. Conclusiones: Los resultados obtenidos en este estudio entregan pistas al momento de abordar la educación financiera, donde debe considerarse que la cultura materialista del modelo económico neoliberal impacta en las actitudes, valores y propensión al endeudamiento de los adolescentes y posteriormente adultos.


Abstract Introduction: Consumer spending has established itself as a means of social interaction, generating high levels of indebtedness among the Chilean population. Adolescents have been especially sensitive to this situation, since through consumption they have access to symbolic elements associated with the construction of identity. The objective of this research is to determine the existence of relationships between material values, influence of peers, and attitudes towards money with regard to attitudes towards hedonic indebtedness in Chilean high school students. Method: Of a sample of 1297 Chilean high school students, 46% are men and 54% are women, corresponding to the cities of La Serena, Coquimbo, Santiago and Temuco. The scales of Attitudes towards Indebtedness, Materialism for Adolescents, Scale of Susceptibility to the Influence of Peers and the Scale of Attitudes towards Money were applied. The data were analyzed through a hierarchical multiple linear regression. Results: The results indicate that there is a statistically significant relationship between sex, material values, peer effect and attitudes towards money with respect to hedonic indebtedness. Conclusion: The results obtained in this study provide clues when approaching financial education in adolescents, where it must be considered that the materialistic culture of the neoliberal economic model impacts on the attitudes, values ​​and propensity to indebtedness of adolescents and later adults.

RESUMEN

BACKGROUND: With the increase in internet use, new forms of child victimization like Online Sexual Abuse (OSA) have emerged. Children and adolescents rarely disclose these incidents and most disclosure happens around peers. OBJECTIVE: This research addresses the perspective of adolescents (not victims of OSA), potential recipients of the disclosure, within the context of disclosure of OSA committed by either adult or peer perpetrators. METHODS: The study was performed in two stages. We interviewed adolescents in Scotland and then conducted focus groups with adolescents from Chile. PARTICIPANTS AND SETTING: 51 adolescents (6 from Scotland and 45 from Chile) aged 15-20 years participated. RESULTS: Despite differences in age and cultural contexts, there were similarities in responses. Obstacles of disclosure included lack of clarity of OSA, prior levels of personal vulnerability, and gender factors (stereotypes and stigmatization). On the other hand, the disclosure process would be easier for adolescents with more personal resources (e.g. self-confidence) and when they have a supportive social environment, which includes parents, but especially peers. CONCLUSION: Disclosure of OSA is considered similar to the disclosure of offline sexual abuse. However, differences such as a lack of clarity regarding the boundaries of the relationships on the Internet, and presence of a generational gap between adolescents and their parents or tutors in the use of internet makes early disclosure of OSA highly challenging. Plans to facilitate disclosure should consider different components: behavioral (risky behaviors), emotional (feelings of fear and shame) and cognitive (lack of information, self-blame, stigma). This should be focused on adolescents, potential recipients of disclosure (parents, authorities and peers) and society, where the prejudices and practices that prevent disclosure begin.

RESUMEN

This study tested culture-general and culture-specific aspects of adolescent developmental processes by focusing on opportunities and peer support for aggressive and delinquent behavior, which could help account for cultural similarities and differences in problem behavior during adolescence. Adolescents from 12 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States) provided data at ages 12, 14, and 15. Variance in opportunities and peer support for aggression and delinquency, as well as aggressive and delinquent behavior, was greater within than between cultures. Across cultural groups, opportunities and peer support for aggression and delinquency increased from early to mid-adolescence. Consistently across diverse cultural groups, opportunities and peer support for aggression and delinquency predicted subsequent aggressive and delinquent behavior, even after controlling for prior aggressive and delinquent behavior. The findings illustrate ways that international collaborative research can contribute to developmental science by embedding the study of development within cultural contexts.

RESUMEN

BACKGROUND: Although a significant amount of literature has explored peer sexual harassment in higher education, little is known about peer sexual harassment in primary and middle school. Among existing studies, most have examined individual student characteristics that predict peer sexual harassment without considering the importance of the classroom and school context, which may prevent or promote such harassment. OBJECTIVE: The purpose of this study was to identify individual and school-related factors predicting sexual harassment victimization. METHODS: A sample of 17,364 Chilean students from Grades 5 through 8 in 405 schools with low socioeconomic status answered instruments concerning peer sexual harassment, other types of peer victimization and discrimination, and perceptions of classroom and school climate and norms against sexual harassment. Data were analyzed through hierarchical multivariate regression. RESULTS: Experiences of being sexual harassed by other students were reported by 13.5 % of students, with higher frequencies in male students, students from Grades 5 and 6, and students with lower individual socioeconomic status. School-related experiences of being discriminated against due to sexual orientation, ethnic origin, and disability were the strongest predictors of sexual harassment victimization. CONCLUSION: We discuss how peer sexual harassment might be understood as a consequence of peer social discrimination based on sexism, racism, and ableism. We also discuss the need to provide inclusive school climate policies that allow all students to feel safe and included.

RESUMEN

O objetivo deste estudo foi analisar se os fatores sociodemográficos moderam a associação da prática de atividade física dos pais e dos amigos com o nível de atividade física dos adolescentes. Trata-se de um estudo epidemiológico transversal, realizado com 2.859 adolescentes (57,8% sexo feminino) de 14 a 19 anos de idade do município de João Pessoa, Paraíba. O nível de atividade física dos adolescentes e a prática de atividade física dos pais e dos amigos foram mensurados por questionários. A prevalência de adolescentes fisicamente ativos foi de 50,2% (IC95%: 47,3-53,1), sendo mais elevada no sexo masculino (66,3%; IC95%: 63,7-69,0) comparada ao feminino (38,4%; IC95%: 36,1-40,8). Os resultados da regressão logística binária demostraram que há associação entre a prática de ativida-de física dos pais e dos amigos e o nível de atividade física dos adolescentes (p < 0,001). No entanto, essa associação é moderada por fatores sociodemográficos (sexo e classe econômica). A magnitude da medida de associação entre a prática de atividade física dos amigos e a dos adolescentes foi mais elevada nos adolescentes do sexo masculino (OR = 5,02; IC95%: 2,73-9,26 vs. feminino OR = 2,21; IC95%: 1,55-3,14) e de classe econômica A/B (OR = 3,90; IC95%: 2,39-6,39 vs. classe C/D/E: OR = 2,27; IC95%: 1,53-3,37). A prática de atividade física da mãe se associou de forma significativa e positiva com o nível de atividade física nos adolescentes de classe econômica A/B (OR = 1,87; IC95%: 1,32-2,62). Conclui-se que os fatores sociodemográficos moderam a associação da prática de atividade física dos amigos e da mãe com o nível de atividade física dos adolescentes. A magnitude da associação entre essas variáveis variou com o sexo e a classe econômica dos adolescentes.


The objective of this study was to analyze if the sociodemographic factors moderate the association of physical activity practice of parents and friends, and the level of physical activity among adolescents. It was an cross sectional epidemiological study with 2,859 adolescents (57.8% female) 14-19 years old of the city of João Pessoa, Paraíba. The level of physical activity among adolescents and the physical activity of parents and friends were measured by questionnaires. The prevalence of physically active adolescents was 50.2% (95%CI: 47.3-53.1), being higher in males (66.3%; 95%CI: 63.7-69.0) compared to female (38.4%; 95%CI: 36.1-40.8). The results of binary logistic regression analysis showed that there is an association between physical activity of parents and friends and the level of physical activity among adolescents (p < 0.001). However, this association is moderated by sociodemographic factors (sex and economic class). The magnitude of the measure of the association between the practice of physical activity of friends and adolescents was higher in male (OR = 5.02; 95%CI: 2.73-9.26 vs. female OR = 2.21; 95%CI: 1.55-3.14) and A/B economic class adolescents (OR = 3.90; 95%CI: 2.39-6.39 vs. class C/D/E: OR = 2.27; 95%CI: 1.53-3.37). The physical activity of the mother was associated significantly and positively with the level of physical activity in adolescents of A/B economic class (OR = 1.87; 95%CI: 1.32-2.62). We conclude that sociodemographic factors moderate the association of physical activity from friends and from the mother with the level of adolescents physical activity. The magnitude of the association between these variables varied with sex and economic class of adolescents.

RESUMEN

Resumen El uso intensivo de internet puede contribuir a desarrollar disfunciones psicosociales graves en la adolescencia. El objetivo de esta investigación es analizar las relaciones de la percepción de eficacia académica con el uso de internet para ocio, los estilos de crianza y los problemas exteriorizados e interiorizados en la adolescencia (agresividad proactiva, reactiva, física y verbal, afiliación a pares rebeldes e inestabilidad emocional). Han participado 762 adolescentes de 12 a 17 años (M = 13.69; DT = 1.40; varones 52.8%). Utilizan internet en tiempo de ocio entre cero y 98 horas semanales, de ahí que la población se haya distribuido en cuartiles. Las variables se han obtenido a través de pruebas estandarizadas. Los análisis estadísticos se basan en metodología descriptiva y predictiva. Los resultados han permitido obtener tres conclusiones. Primera, el número de horas de internet para fines recreativos se relaciona con una peor eficacia académica percibida. Segunda, los adolescentes que usan Internet intensamente perciben más permisividad de los padres y menos apoyo y comunicación por parte de los padres. Estos adolescentes presentan más riesgo de conectarse con pares rebeldes y tienen índices más altos de inestabilidad emocional y agresividad (reactiva, proactiva, física y verbal). Tercera, la paternidad más punitiva, la agresividad y la afiliación a pares rebeldes aumentan el uso intensivo de Internet. Esta investigación corrobora la necesidad de una formación adecuada, dirigida a fomentar el apoyo y la comunicación paterno-filial para educar el uso racional y responsable de internet de ambos, padres y adolescentes.


Abstract The intensive use of the Internet can contribute to the development of serious psychosocial dysfunctions in adolescents. The purpose of this research is to analyze the relationships between achievement perceived with the leisure use of the internet, parenting, and externalized and internalized problems during adolescence (aggressiveness reactive, proactive, physical and verbal, affiliation with deviant peers and emotional instability). The sample is made of 762 adolescents from 12 to 17 years old (M = 13.69, SD = 1.40), with 52.8% of males and 47.2% of females. The use of internet in leisure time is between 0-98 hours per week. Hence the population has been distributed in quartiles. The variables have been obtained through standardized tests. Statistical analyzes are descriptive and predictive methodology. The analyses carried out have allowed us to obtain three conclusions. First, the number of hours of internet for recreational purposes is related to worse achievement perceived of the adolescent. Second, it has been found that adolescents who use Internet intensively greater perceived permissiveness of the parents and a lower support and communication with them. These adolescents present an increased risk of joining deviant peers and have higher rates of emotional instability and aggressiveness (reactive, proactive, and physical and verbal). Third, more punitive parenting, aggressiveness and affiliation with deviant peers boost the intensive use of the internet. This empirical research corroborates the need for adequate training aimed at fostering parental-child support and communication to educate the rational and responsible use of the Internet by both parents and adolescents.

RESUMEN

This study evaluated whether the relationship between socioeconomic status (SES) and moderate-to-vigorous physical activity (MVPA) is mediated by social support of peers and parents. A cross-sectional study included students (n = 1182) aged 11 to 18 years who were recruited in 2014 from public schools in Fortaleza, Brazil. Participants completed a questionnaire to assess all variables. Mediation analyses were performed to determine the role of parental support and peer support on the relationship between SES and MVPA. Also, moderated-mediation analyses with estimating of conditional indirect effects were performed in order to identify whether gender is a moderator of the mediating effect. A positive and significant association between SES and MVPA was found among Brazilian students, and social support of parents and peers were significant mediators of this relationship. Conditional indirect effects showed that both parental and peer support had a significant indirect effect among boys; only parental support had a significant indirect effect among girls. These results suggest that improving social support can help reduce the impact of SES on physical activity among Brazilian adolescents.

RESUMEN

Resumo A generalização do uso das redes sociais online, tem trazido oportunidades e constrangimentos ao mesmo tempo-ou até mais depressa-que a investigação e o conhecimento sobre este tópico. Neste trabalho, pretendemos explorer o papel de variáveis pessoais e psicossociais no uso do Facebook, recorrendo a um conjunto de questionários de autorrelato junto de uma amostra de 386 adolescentes portugueses. Os resultados obtidos permitem verificar diferenças na utilização em função do género, uma relação positiva com a idade, a autorregulação e autoestima, sendo a interação com pares da sua rede de contactos offline o mais forte preditor para o uso das redes sociais. Estes dados sugerem o papel desta aplicação como um meio para manter o contacto com os pares.


Abstract The widespread use of social networks has brought opportunities and constraints at the same time, even faster than research and knowledge on this topic. In this paper, we intend to explore the role of personal and psychosocial variables in Facebook use, considering a set of self-report questionnaires to a sample of 386 Portuguese adolescents. We found gender differences in social network use, a positive relationship with age, self-regulation and self-esteem, with peer interaction with offline contacts as the strongest predictor for social network use. These data suggest the role of this application as a mean to maintain contact with peers.

RESUMEN

Most studies tend to characterize peer influences as either positive or negative. In a sample of 1815 youth from 14 different schools in Caracas, Venezuela, we explored how two types of peer affiliations (i.e., deviant and drug-using peers) differentially mediated the paths from positive parenting to youth's externalizing behavior and licit and illicit drug use. We used Zero Inflated Poisson models to test the probability of use and the extent of use during the past 12 months. Results suggested that peer influences are domain specific among Venezuelan youth. That is, deviant peer affiliations mediated the path from positive parenting to youth externalizing behaviors, and peer drug-using affiliations mediated the paths to the drug use outcomes. Mediation effects were partial, suggesting that parenting explained unique variance in the outcomes after accounting for both peer variables, gender, and age. We discuss implications for the development of screening tools and for prevention interventions targeting adolescents from different cultures.

RESUMEN

The aim of this study is to analyze a set of socializing agents for sport and physical activities and to establish their relationship with leisure time sport and physical activities behaviors and practice patterns in samples of teenage students with different sociocultural backgrounds. The sample included 2168 students in their first year of secondary education, 423 of them being from Costa Rica, 408 from Mexico, and 1337 from Spain (1052 male students, 1037 female students, and 79 students who did not specify gender) aged 11-16 years old (M = 12.49; SD = .81). A validated questionnaire with questions about leisure time sport and physical activities and socializing agents was used. Descriptive, inferential, and multinomial logistic regression analyses were carried out with SPSS 17.0 to compare all three countries. Costa Rica had the most active students, best friends' inactivity, and unsupportive parents being the agents predicting inactivity and a low level of sport and physical activities. Mexico has a high dropout rate and inactive students exceed active ones; no agent predicts inactivity or sport and physical activities pattern. Spain has the highest level of sport and physical activities practice, and parents, siblings, and friends are predicting agents of inactivity together with unsupportive parents and friends.

RESUMEN

Los pares contribuyen a la presencia de insatisfacción corporal y conductas alimentarias anómalas, mismas que tienen su pico de ocurrencia durante la adolescencia; sin embargo, se ha sugerido que los pares pueden incidir desde edades más tempranas. Por ello, los propósitos de este estudio fueron: evaluar la influencia de pares, la interiorización del ideal corporal, la insatisfacción corporal y las conductas alimentarias anómalas en preadolescentes vs. adolescentes; y analizar la influencia de pares en la predicción de la insatisfacción corporal y las conductas alimentarias anómalas. Participaron 273 preadolescentes y 175 adolescentes, hombres y mujeres, quienes completaron cuatro cuestionarios, además de recabar su peso y estatura. La prueba t de Student solo reveló diferencias entre los grupos en índice de masa corporal, interacción con pares, interiorización del ideal corporal y conductas alimentarias anómalas, siendo los adolescentes quienes obtuvieron mayores puntuaciones en las primeras tres variables. Los análisis de senderos mostraron que en ambos grupos los pares tuvieron efecto directo sobre la insatisfacción corporal, misma que actuó como mediadora del efecto sobre el comportamiento alimentario. Se concluye que la insatisfacción corporal no difiere entre preadolescentes y adolescentes, y que en ambos la influencia de pares mostró ser un importante factor predictor.


Peers contribute to the development of body dissatisfaction and disordered eating behaviors, conditions that show their peak occurrence during the adolescence; however, literature has suggested that peers may influence since earlier ages. Therefore, the objective of this study was to evaluate peer influence, internalization of the body ideal, body dissatisfaction and disordered eating behaviors, in preadolescents vs. adolescents; and to analyze the peer influence in the development of disordered eating behaviors and body dissatisfaction. A total of 273 preadolescents and 175 adolescents' men and women answered four questionnaires, additionally weight and height was measured. The t Student test showed differences between groups only in body mass index, interaction with peers, internalization of body ideal and eating behaviors, being adolescents who obtained higher scores in the first three variables. Path analysis showed that in both groups peers influenced body dissatisfaction, which act as a mediator of disordered eating behavior. It is concluded that body dissatisfaction is not different between preadolescents and adolescents and in both groups peer influence was an important predictive factor.

RESUMEN

PURPOSE: The purpose of the study is to examine (1) whether family and peer marijuana use are independently related to adolescent marijuana use in Chile, (2) whether family and peer marijuana use are associated with adolescent marijuana dependence in adolescents using marijuana, and (3) whether the adolescent's age moderates the association between family or peer use and adolescent marijuana use and/or dependence. METHOD: This study used data from the National Survey on Drug Use in the General Population in Chile (a cross-sectional observational study), which was conducted in 2008 and 2010 in 4413 adolescents aged 12-19. Adolescents answered questions about their past-year marijuana use and dependence (ICD-10 criteria) and the marijuana use of their family and peers. Logistic regressions were performed while controlling for confounders. RESULTS: Adolescents who had a family member who used marijuana were five times more likely to use the drug. Adolescents with a close friend who used marijuana were eight times more likely to use marijuana. When adolescents were using marijuana, they were three times more likely to be dependent if they had a family member who used the drug. However, no significant relationship was found between peer use and dependence. No statistically significant interactions were found between family or peer use and age. CONCLUSION: Family and peer marijuana use was independently associated with adolescent's past-year marijuana use; however, only family marijuana use was statistically associated with adolescent's marijuana dependence.

RESUMEN

Se analizan los fenómenos del acoso escolar y el ciberacoso desde una perspectiva analítica y teórica. A partir de una definición consensuada de ambos conceptos, se intenta identificar los factores de riesgo en la génesis y desarrollo del acoso en las aulas, y los efectos que produce en los distintos implicados. Además, se presenta una síntesis de algunos de los principales trabajos de investigación realizados en la última década, y el estudio de las medidas educativas y penales que arbitra el ordenamiento jurídico español en la erradicación de la violencia escolar. Se concluye que la lucha contra el acoso requiere la intervención conjunta y coordinada de diferentes instancias: la familia, la comunidad educativa y los servicios de protección de menores, en la prevención y detección de situaciones de riesgo


The school harassment and ciberbullying phenomena are examined from an analytical and theoretical perspective. From a consensus definition of both concepts, an identification of risk factors in the genesis and development of intimidation in classrooms is intended in order to understand the impact and effects produced on the different individuals concerned. In addition, a synthesis of some of the main research works carried out in the past decade is offered, as well as the study of some educational and criminal measures and policies arbitrated by the Spanish legal system in the eradication of school violence. It is finally concluded that the fight against bullying, harassment and intimidation requires joint and coordinated intervention of different groups, authorities and bodies like families, the educational community and minor protection services in the prevention and detection of risk situations


Os fenômenos do assédio escolar e o ciberassédio são analisados de uma perspectiva analítica e teórica. De uma definição consensuada de ambos os conceitos, tenta-se identificar os fatores do risco na gênesis e no desenvolvimento do assédio nas aulas, e os efeitos que produzem nos diferentes implicados. Além, uma síntese de alguns dos trabalhos principais da pesquisa feitos na última década é apresentada, e também o estudo das medidas educativas e penais que arbitra o ordenamento jurídico espanhol na erradicação da violência escolar. Conclui-se que a luta contra o assédio requer a intervenção conjunta e coordenada de diferentes instâncias: a família, a comunidade educativa e os serviços da proteção dos menores, na prevenção e na detecção de situações do risco

RESUMEN

Resumen: La imagen corporal es un tópico relevante en el desarrollo de la identidad durante la adolescencia, donde los factores sociales son decisivos en la determinación de las expectativas individuales. Este estudio describe y analiza la percepción que mujeres adolescentes tienen acerca de la influencia de los aspectos socioculturales en su imagen corporal. El enfoque de investigación fue cualitativo, exploratorio y descriptivo, basado en la teoría fundamentada. Se entrevistó a cinco mujeres adolescentes de entre 16 y 18 años de edad. Los resultados muestran que existe una experiencia de la imagen corporal caracterizada por sentimientos ambivalentes y diferentes grados de insatisfacción corporal. En general, las participantes sobrevaloran la importancia del aspecto físico y, específicamente, la delgadez es considerada signo de atractivo, éxito y perfección; prototipo estético que favorece la insatisfacción corporal. Los parámetros socioculturales percibidos como más influyentes fueron los medios masivos de comunicación, especialmente las redes sociales digitales, que superan a los pares y a la familia. Se concluye que el fortalecimiento de la capacidad de juicio crítico para discernir entre los ideales corporales y los cuerpos reales podría favorecer la prevención de problemas alimentarios en las mujeres adolescentes.


Abstract: Body image is a relevant topic in the development of identity during the adolescence, where social factors are significant in determining individual expectations. This study aims to describe and analyze the perception that female adolescents have about the influence of sociocultural factors on their own body image. This research has a qualitative, exploratory and descriptive approach based on the Grounded Theory. Five adolescent girls aged between 16 and 18 years were interviewed. Results show that body image is characterized by ambivalent feelings and different degrees of body dissatisfaction. In general, participants overvalue physical aspects, for instance, thinness is believed as a sign of attractiveness, success and perfection, prototype linked to body dissatisfaction. The more influential sociocultural parameters were mass media, especially online social networks, peers and family. It is concluded that strengthening critical judgment skills to distinguish between the ideal body and the real body could enhance the prevention of eating disturbances in adolescent women.

RESUMEN

Objetivo. El presente estudio tuvo como objetivo evaluar la percepción de la creatividad en niños, padres y pares, y el efecto de estas percepciones sobre la producción creativa de los niños en actividades de papel y lápiz. Método. Participaron 359 alumnos de 9 a 13 años de diferentes escuelas y colegios de la provincia de Entre Ríos de la República Argentina. Para conocer la producción creativa, los niños completaron la prueba de figuras del Test de Pensamiento Creativo de Torrance Forma B. Para estudiar la valoración de los pares, padres y niños sobre la creatividad se aplicó el Sociograma "Compañero creativo", la Escala de Personalidad Creadora (versión heteroevaluación a los padres o tutores) y la versión autoevaluación a los niños de 11 a 13 años. Resultados. Los resultados mostraron que tanto la percepción parental (F (2, 356) = 6.55, p = 0.002), así como la evaluación que realizan los pares (F (2, 356) = 4.90, p = 0.008) sobre la creatividad mejoran la producción creativa del niño en las tareas de papel y lápiz. No se encontraron diferencias significativas en la producción creativa según la evaluación del niño sobre su propia creatividad. Conclusión. Los datos muestran la importancia cardinal de los factores contextuales, particularmente, la percepción de los padres y de los pares en los procesos de formación del yo en cuanto a las competencias y habilidades que son necesarias para realizar una actividad creadora.


Objective. The present study aimed at assessing the perception of creativity in children, parents and peers, as well as the effect of these perceptions on the child's creative output in paper-and-pencil activities. Method. The study involved 359 students aged 9-13 years from different schools and colleges of the province of Entre Ríos, Argentina. To know the creative production, children completed the Figural Torrance Test of Creative Thinking (TTCT; Torrance, Ball y Safter, 1992), Form B. To study the valuation of peers, parents and the own child on creativity, the Sociogram "Creative peer" for all children, the Creative Personality Scale (CPS; 2004, in its hetero-evaluation version for parents or guardians) and the Self-evaluation version for children aged 1113 years were administered. Results. The results showed that both parental perception (F (2, 356) = 6.55, p = 0.002) and peers' evaluation (F (2, 356) = 4.90, p = 0.008) on creativity improve the child's creative production in paper-and-pencil activities. No significant differences were found in the creative production according to the child's self-perception of his/her creativity. Conclusion. Data demonstrate the fundamental importance of contextual factors, mainly the perception of parents and peers in the process of the formation of the self, in terms of competencies and skills that are necessary to carry out a creative task.


Escopo. O presente estudo teve como objetivo avaliar a percepção da criatividade em crianças, pais e pares, e o efeito de estas percepções sobre a produção criativa das crianças em atividade de papel e lápis. Metodologia. Participaram 359 alunos de 9 a 13 anos de idade de diferentes escolas e colégios da província de Entre Ríos da República Argentina. Para conhecer a produção criativa, as crianças completaram a prova de figuras do Test de Pensamento Criativo de Torrence Forma B. Para estudar a valoração dos pares, pais e crianças sobre criatividade foi aplicado o Sociograma "Companheiro criativo", a Escala de Personalidade Criadora (versão heteroavaliação aos pais ou tutores) e a versão auto-avaliação às crianças de 11 a 13 anos de idade. Resultados. Os resultados mostraram que tanto a percepção parental (F(2,356) = 6.55, p = 0.002), assim como a avalição que foi feita pelos pares (F(2,356) = 4.90, p= 0.008) sobre a criatividade melhoram a produção criativa da criança em tarefas de papel e lápis. Não foram achadas diferenças significativas na produção criativa segundo a avalição da criança sobre sua própria criatividade. Conclusão. Os dados mostram a importância cardinal dos fatores contextuais, particularmente, a percepção dos pais e dos pares nos processos de formação do Eu em quanto às competências e habilidades que são necessárias para fazer uma atividade criadora.

RESUMEN

El objetivo de este estudio fue determinar un modelo de relaciones para predecir la ideación suicida de adolescentes escolarizados. Se propuso un modelo basado en la conducta suicida de los iguales, el apoyo del padre y de la madre, la violencia familiar y la depresión. La muestra estuvo conformada por 912 sujetos. Los resultados obtenidos mediante un path analysis indican que los adolescentes con síntomas de depresión optan por amigos con conductas suicidas y estos, además, aumentan directamente la probabilidad de ideación suicida.

RESUMEN

Este estudio describió y estableció diferencias del perfil estructural/dinámico familiar y social de adolescentes de acuerdo a la prevalencia de vida de uso de cannabis. Estudio cuantitativo, descriptivo transversal. Muestra no probabilística de 156 adolescentes incluidos en educación secundaria. Menor apoyo familiar, menor grado de confianza y consumo de sustancias ilegales caracterizó la dinámica de familias de quienes han probado cannabis al menos una vez en la vida. Una mayor cantidad de amigos de quienes han probado cannabis alguna vez consumen cannabis, alcohol, tabaco y otras sustancias. Las parejas de quienes han consumido cannabis no funcionan como factor de protección ya que consumen más sustancias que parejas de quienes nunca han probado cannabis. Los programas de prevención en uso de cannabis deben hacer mayor hincapié en el trabajo del aspecto dinámico de las familias y de los adolescentes en relación con sus pares incluyendo sus parejas.


This study described and established differences in the structural/dynamic family and social profile of adolescents according to the lifetime prevalence of cannabis. Quantitative, descriptive and cross-sectional study. Non-random sample of 156 adolescents included in secondary education. Low family support, less confidence and consumption of illegal substances characterized the dynamics of families of who have tried cannabis at least once in life. A greater number of friends of who have ever used cannabis use more cannabis, alcohol, tobacco and other substances. Couples of who have used cannabis not function as a protective factor as they consume more substances that couples who have never tried cannabis. Cannabis prevention programs have to do a greater emphasis on the work of the dynamic aspects of families and relationships of adolescents with their peers including their partners.
