Resumo: O objetivo do presente trabalho foi avaliar a agressividade de ratos expostos concomitantemente ao cádmio (Cd) e ao estresse por imobilização (EI). Ratos Wistar, machos, provenientes do Biotério Central da Unesp, foram divididos em 2 grupos experimentais: A- animais intrusos (sem tratamento) e B- animais residentes, os quais receberam um dos seguintes tratamentos: acetato de sódio (controle); acetato de cádmio (solução a 50 ppm de Cd na água de beber); submetidos ao estresse por imobilização (30 minutos, 3 vezes ao dia, 5 dias por semana, durante 4 semanas); expostos ao Cd e concomitantemente submetidos ao estresse por imobilização. O comportamento de agressividade dos animais residentes foi avaliado ao final da última semana do experimento, baseando-se no paradigma do animal intruso/residente, segundo os seguintes parâmetros: número total de ataques (NTA), tempo de latência para a 1º mordida (TLM), tempo total de manifestações de ataques (TTMA) e escore de agressão composta (EAC). Após a avaliação do comportamento de agressividade, o sangue e o cérebro dos animais foram coletados para dosagem de Cd por espectrometria de absorção atômica. O nível de cádmio no sangue não se alterou, mas no cérebro foi aumentado. Observou-se que exposição ao Cd ou estresse por imobilização sozinhos, não modificaram o NTA, TLM, TTMA ou EAC, porém, exposição ao Cd e EI concomitantemente aumentou significantemente o NTA, TTMA e o EAC. Esses resultados sugerem que exposição dos ratos à baixa dose de Cd associado ao estresse por imobilização pode causar interação e provocar aumento da agressividade dos animais. Um possível papel da serotonina (5-HT) e nível aumentado de cádmio no cérebro, como mecanismos responsáveis pela agressividade anormal observada, é discutido. / Abstract: The aim of this study was to assess the aggressiveness in rats concomitantly exposed to cadmium (Cd) and stress by immobilization (EI). Male Wistar rats, 70 days old, from the Biotério Central - UNESP, Botucatu - SP, were allocated into 2 experimental groups: A-intruder animals (without treatment) and B-resident animals, which received one of the following treatments: sodium acetate (control); Cadmium acetate (50 ppm Cd in drinking water); stress by immobilization (30 min, three times per day, five days per week, during four weeks); Cd exposure and concomitant stress by immobilization. The aggressive behavior of resident rats was evaluated at the end of the last experimental week based on the intruder/resident animal paradigm, according to the following parameters: total number of attacks (TNA), latent time for the first bite (LTB), total time of attack manifestations (TTAM), and composed aggression score (CAS). After aggressive behavior assessement, blood and brains were collected to determine Cd through atomic absorption spectrometry. Cd level was not altered in the blood but increased in the brain. Cd exposure or EI, alone, did not modify TNA, LTB, TTAM or CAS but Cd exposure and EI, concomitantly, increased significantly TNA, TTAM and CAS. These results suggest that rat exposure to low Cd level associated with stress by immobilization may lead to interaction with consequent increased animal aggressiveness. A possible paper of serotonin (5-HT) and increased brain Cd levels as responsible mechanisms by the observed abnormal aggressiveness is discussed. / Orientador: José Ricardo de Arruda Miranda / Coorientador: Antonio Francisco Godinho / Banca: Ethel Lourenzi Novelli / Banca: João Lauro Viana de Camargo / Mestre

M.Ed. / The goal of this research study was to provide Psycho-Educational guidelines to assist adolescent learners to manage aggression in a constructive manner. The participants in this research study were adolescent learners at age of fifteen to seventeen years in Secondary Schools in the of Klerksdorp area. Adolescence is a phase in human development that is synonymous with change, namely, physical, emotional and cognitive changes. It is a crucial phase of development. Aggression is simply defined as a behavior that is intended to hurt someone either physically or psychologically (Weiten, 1992:397). However there are many theorists who define aggression differently but state anti-social behavior as a characteristic. The researcher wanted to formulate guidelines after exploring and describing the perceptions of black adolescence on aggression. It was because this aggressive behavior was impacting on their future successes. The research objectives were as follows: „« To explore and describe the perception of black adolescents of aggression in an informal settlement „« To formulate guidelines to assist black adolescents to manage aggression in a constructive manner. The qualitative research approach helps the researcher to understand and interpret adolescents¡¦ perception on aggression. The information gathered in this study would help determine topics for further research on adolescents¡¦ perceptions on aggression. Focus group interviews were conducted. This study was explorative and descriptive as it aimed to obtain adolescents¡¦ perceptions on aggression. The researcher attempted to find out how adolescents perceived aggression by conducting focus group interviews. Interviews were conducted with four groups. The major themes were: „« Black adolescents in an informal settlement school express different views on what aggression is „« Black adolescents in an informal settlement school experience forms and acts of aggression at school „« Black adolescents experience a sense of being so victimized in schools that it made their school lives miserable. „« View points that necessary structures should be put in place with the objective of providing guidelines to assist black adolescents in an informal settlement school to manage aggression in a constructive manner From the interviews conducted, recommendations were made to reduce the problems caused by aggression. / Prof. C.P.H.

M.A.(Psychology) / The principal aim of the present study was the determination of the role of aggression, the self concept and stereotyping in obesity. A subsidiary goal was to construct a scale for the measurement of stereotyping. A scale for the measurement of the stereotyping of obese women was constructed and applied to a general sample of 229 first year psychology students. This scale, namely the Attitude Questionnaire (AQ), comprised forty 7-point scales. The first 20 scales were designed to characterise obese women and the last 20 scales to characterise normal weight women. Separate item analyses were done for the first and the second parts of the scale. The first part of the scale yielded a reliability coefficient of 0,86 according to Kuder-Richardson Formula 20 and the second part a coefficient of 0,87. The first part of the scale was subjected to a factor analysis to determine its structure. It yielded a single second-order factor which was defined as "general stereotyping of obese women". Similarly the second part of the AQ yielded a single second-order factor which was defined as "general stereotyping of normal weight women". The scores of the student sample, in respect of the AQ,were used in order to determine their perception of obese women compared with normal weight women. The vector of means of obese women were contrasted with the vector of means of normal weight women and the difference between the two vectors was tested with the aid of Hotelling T2 (dependent test). The Hotelling T2 proved to be statistically significant and was consequently followed up by a series of t-tests. From the t-tests it transpired that the perception of the student sample of obese women was largely negative. A battery of tests comprising the Picture Situation Test (PST), the Buss-Durkee Hostility Inventory, the Adolescent Self-Concept scale (ASCS) and the newly constructed AQ, was administered to 50 obese women who were members of the . Weight Watchers organisation (experimental group) and 50 Weight Watchers organisation (experimental group) and 50 normal weight women who worked for a large cosmetic company (control group)
