Ecological-transaction model approach of adolescents’ parental maltreatment and peer-bullying: the moderating role of bullying at the classroom

INTRODUCTION: The present study examined the ecological-transactional model delineated by Cicchetti and Lynch (1993) and the nature of the association between adolescents’ parental maltreatment and victimization and bullying at school. METHOD: Multivariate multilevel regression analyses were conducted on a sample of 2.852 adolescents between the ages of 12 and 17 from 25 secondary schools. Data was nested across 133 classrooms. Classrooms level variables and individual variables in relationship to parental maltreatment, behavioural disorders, sex, and bullying and victimization were included in the analysis. RESULTS: Results indicated that adolescents who reported suffering violence at home, showed more vulnerability to becoming victims of bullying at school, with the relationship being moderated by the level of bullying in the classroom. It was also examined the role of behavioural disorders and a relation between these factors was found amongst the bullies but not the victims. DISCUSSION AND CONCLUSION: This study uses the systemic perspective of ecological-transactional model on child maltreatment to show the importance between the school and home microsystems in the perpetuation of victimization. The results imply that what children experience at home might cause emotional and behavioural differences in varying classroom climates at school. Therefore, understanding the interactions between systems’ transaction of socialisation mechanisms might contribute for effective anti-bullying programs

Análisis del Maltrato Físico en la Familia y su Influencia en Variables del Contexto Educativo [Analysis of the Physical Abuse in the Family and its Influence in Variables of the Educational Context]

This study analyzes the relationship between physical abuse in the family context and its influence on the educational context variables (academic performance and social behavior). A total of 2.852 students aged between 12 and 17 years participated in the study. The results highlight that the students who were abused in the family have higher numbers of fail marks, a lower level of social acceptance in the peer group as well as a greater involvement in the dynamics of bullying in both, the role of aggressor and as the victim. The results are discussed in relation to the importance of the type of family socialization based on coercion and abuse and behavior of students in the classroom

Acoso escolar y depresión: el efecto moderador del apoyo social, el rechazo y el perfil de la victimización

Peer relationships can be shaped as influential factors in the prevalence of bullying episodes. This research aims to analyze the effect of school bullying on the levels of depression of the victims and to what extent it is affected by social support and status in the group and by the profile of victimization. Several hierarchical linear regression analyses were calculated, in a sample of 1063 students aged 10 to 14 (47.8% of girls, M = 11.59 years, SD = 1.21 years), from 10 school of the Region of Madrid. The degree of influence of the studied variables was observed: lack of social support, peer rejection, withdrawal and impulsivity behaviors, and the relationship of all of them with victimization and depression. Findings revealed the influence of the lack of social support on the depression of victimized students. However, peer rejection did not show influence on the levels of depression of the victims. In addition, victimization associated with internalizing characteristics showed a greater association with depression than victimization associated with an externalizing profile.Las relaciones dentro del grupo de iguales pueden conformarse como factores influyentes en la prevalencia de los episodios de acoso escolar. Esta investigación tiene como objetivo analizar el efecto del acoso escolar sobre los niveles de depresión de las víctimas y en qué medida se ve afectado por el apoyo social, el estatus en el grupo y por el perfil de la victimización. Se calcularon varios modelos de regresión jerárquica lineal, en una muestra de 1063 alumnos, entre 10 y 14 años (47.8 % de chicas; M = 11.59 años, DT = 1.21 años), de 10 centros educativos de la Comunidad de Madrid. Se observó el grado de influencia de las variables estudiadas: falta de apoyo social, rechazo de los pares, conductas de retraimiento y de impulsividad, y la relación de todas ellas con la victimización y la depresión. Los resultados revelaron la influencia de la falta de apoyo social en los alumnos victimizados sobre la depresión. Sin embargo, el rechazo de los iguales no mostró influencia sobre los niveles de depresión de las víctimas. Además, las víctimas con características de tipo internalizante mostraron una mayor asociación con la depresión que las víctimas con características externalizantes

Brand personality as a consistency factor in the pillars of CSR management in the new normal

ABSTRACT During such a complex crisis as the one experienced by humanity since the first quarter of 2020, it is necessary to develop tools that contribute to creating the corporate image for organizations that are currently interested in being identified as brands with high social and environmental commitment. Likewise, elements that contribute to building strong brands during a context that has changed consumption priorities are required. For this reason, this paper aims at adapting the dimension of socially responsible brand personality (SRBP), proposed by Mayorga (2017), taking the situationexperienced dueto theCOVID-19 pandemicas anew context. The objectiveof thisresearch is to contribute to the management of corporate social responsibility (CSR) by providing, from a communicative perspective, a tool that optimizes the creation of a socially responsible image by the different stakeholders. The results allow us to conclude that there is a structural modification of the brand personality proposed by Mayorga, which can be presumed to be generated by the current environment, and which, therefore, can be established as a pillar of CSR management in the new normal, from a relational point of view. The findings clearly identify the virtue of integrity in brand personality, which is made up of two attributes, which, in turn, are made up of 17 traits that can identify a socially responsible brand

Diferencias sexuales en los rasgos de personalidad instrumentales y expresivos de adolescentes españoles

Extensive research has shown that people believe that men and women have different personality traits characterizing women with “expressive” traits and men with “instrumental” traits. Because of the controversial nature of this topic, this research examines sex differences in the expressive and instrumental traits of 634 adolescents aged between 14 to 18 years, who answered the Personal Attributes Questionnaire (Spence, Helmreich and Stapp, 1974). The results show sex differences in self-identification with traditional values usually attributed to the other sex, also a change in the sex role stereotypes values, being the overcoming of the sexist stereotype clearer for girls who identified themselves with more instrumental traits.Investigaciones señalan que la gente suele creer que hombres y mujeres tienen rasgos de personalidad diferentes caracterizando a las mujeres con rasgos “expresivos” y a los varones como “instrumentales”. Debido a lo controvertido del tema la presente investigación examina las diferencias sexuales en los rasgos instrumentales y expresivos de 634 adolescentes, con edades comprendidas entre 14 y 18 años, quienes cumplimentaron el Cuestionario de Atributos Personales (Spence, Helmreich y Stapp, 1974). Los resultados muestran diferencias entre sexos en la auto-identificación con los valores tradicionales habitualmente atribuidos al otro sexo al igual que un cambio en los estereotipos de rol sexual, siendo la superación del estereotipo sexista más clara para las chicas quienes se identifican con más rasgos instrumentales

The Use of P63 Immunohistochemistry for the Identification of Squamous Cell Carcinoma of the Lung

6 páginas, 2 figuras, 3 tablas.Introduction While some targeted agents should not be used in squamous cell carcinomas (SCCs), other agents might preferably target SCCs. In a previous microarray study, one of the top differentially expressed genes between adenocarcinomas (ACs) and SCCs is P63. It is a well-known marker of squamous differentiation, but surprisingly, its expression is not widely used for this purpose. Our goals in this study were (1) to further confirm our microarray data, (2) to analize the value of P63 immunohistochemistry (IHC) in reducing the number of large cell carcinoma (LCC) diagnoses in surgical specimens, and (3) to investigate the potential of P63 IHC to minimize the proportion of “carcinoma NOS (not otherwise specified)” in a prospective series of small tumor samples. Methods With these goals in mind, we studied (1) a tissue-microarray comprising 33 ACs and 99 SCCs on which we performed P63 IHC, (2) a series of 20 surgically resected LCCs studied for P63 and TTF-1 IHC, and (3) a prospective cohort of 66 small thoracic samples, including 32 carcinoma NOS, that were further classified by the result of P63 and TTF-1 IHC. Results The results in the three independent cohorts were as follows: (1) P63 IHC was differentially expressed in SCCs when compared to ACs (p<0.0001); (2) half of the 20 (50%) LCCs were positive for P63 and were reclassified as SCCs; and (3) all P63 positive cases (34%) were diagnosed as SCCs. Conclusions P63 IHC is useful for the identification of lung SCCs.This work was partially funded by grants from Fundacion Mutua Madrileña to EC, FLR, and LPA; CIBER Respiratory Disease to ALE (ISCIII-CB06/06); and Red Temática de Investigacion Cooperativa en Cancer (RTICC) to MSC (RD06/0020/0062).
