Perturbações do comportamento alimentar em adolescentes e estilos de vida, sua relação com a percepção do auto-conceito e imagem corporal

Tendo como ponto de partida, o quadro conceptual esboçado a partir dos estudos revistos, procuramos nesta investigação analisar as perturbações do comportamento alimentar em adolescentes/estilos de vida, sua relação com a percepção do auto-conceito e imagem corporal. A amostra foi constituída por 405 alunos (232 do género feminino e 173 do género masculino) do ensino secundário (11º e 12º anos), com idades compreendidas entre os 15 e os 20 anos. Os participantes preencheram um questionário, dividido em 3 partes: sócio-demográfico/estilos de vida, escala sobre a percepção da imagem corporal – Relationship Between Body Image Percent Body Fat Among College Male Varsity Athletes and Non-athletes (Huddy, D. C.; Nieman, D. C. e Johnson, R. L. 1993 ) e escala da percepção do auto-conceito – The self-perception profile for college (Newman & Harter 1986). Neste estudo tivemos como principal objectivo, analisar as perturbações do comportamento alimentar/Índice de Massa Corporal a partir do impacto das variáveis psicológicas como: percepção do auto-conceito, imagem corporal, ambiente familiar, estilos de vida, numa amostra de adolescentes. A determinação do IMC mostra que a maioria dos adolescentes apresenta peso normal (71%). Apenas 14,3% apresentam excesso de peso, 3,2% tem obesidade moderada, 0,7%, obesidade grave e 0,5% obesidade mórbida. A avaliação baseada nas correlações entre as variáveis e entre as variáveis e as sub-escalas, revelaram que os adolescentes do género masculino apresentam uma média mais elevada a nível da percepção do auto-conceito do que o género feminino. Também uma percepção mais desfavorável do auto-conceito, está associada a um elevado índice de massa corporal. O grau de satisfação com o ambiente familiar revela uma mais favorável percepção do auto-conceito. Quanto à relação da percepção que os adolescentes têm relativamente ao auto-conceito e comportamentos afectos aos estilos de vida, há a ressaltar, que uma maior actividade física, está associada, a uma percepção menos favorável do auto-conceito. Os resultados evidenciam uma ausência de relações significativas entre a imagem corporal, o género e a idade. Também no nosso estudo não foi confirmada a hipótese de que a imagem corporal está correlacionada com o IMC. Em relação aos hábitos alimentares e IMC não foi possível comprovar esta hipótese, mas permitiu-nos conhecer alguns comportamentos alimentares.

Influência de um programa de exercícios específicos em estudantes de violino

Introdução: A elevada prevalência de problemas musculosqueléticos relacionados com a performance musical (PMRPM) em estudantes universitários de música, sobretudo violinistas, justifica uma abordagem preventiva junto destes, nomeadamente, através do exercício. Este deve ser específico e baseado nos padrões de movimento durante a performance musical do violinista. Objetivos: verificar a influência de um programa de exercícios específicos (PEE) nos sintomas relacionados com a prática musical, na incapacidade funcional e na autoperceção da performance física e musical, em estudantes universitários de violino. Métodos: estudo quase-experimental baseado num estudo piloto com 24 estudantes para pesquisa da sintomatologia, e 4 para análise cinemática e cinética do gesto técnico. No estudo principal participaram 22 violinistas divididos equitativamente, e por disponibilidade, entre grupo experimental (GE) e grupo de controlo (GC). O GE realizou o PEE bissemanalmente, durante 8 semanas. No momento inicial e após 8 semanas, os participantes preencheram: Questionário de Performance (incluiu Escala Visual Analógica), Disabilities of the Arm, Shoulder and Hand, Oswestry Disability Index versão 2.0, Pain Catastrophizing Scale e Escala de Borg Modificada. Resultados: do estudo piloto constatou-se que os sintomas mais frequentes, dor e fadiga, localizavam-se na cintura escapular, ombros e coluna lombar; os ombros aparentavam maior risco de PMRPM; era necessário aumentar a endurance dos mobilizadores dos membros superiores (principalmente deltóide) e relaxar os estabilizadores da coluna cervical (sobretudo trapézio superior). No final do PEE, o GE apresentou significativamente melhores pontuações do que o GC na percentagem de violinistas com “dor na coluna lombar esquerda” (p=0,007), frequência da dor (U=8,5; W=29,5; p=0,016), número de locais com sintomas (U=18; W=84; p=0,003) e amplificação (U=26; W=92; p=0,021). Conclusão: Um PEE pode produzir efeitos positivos na diminuição dos sintomas relacionados com a prática musical e incapacidade funcional, e na melhoria de alguns parâmetros da performance física autoreportada, em estudantes universitários de violino.

Promoção no ponto de venda: percepções e comportamentos do consumidor

Este estudo enquadra-se no âmbito do Marketing e Comportamento do Consumidor e tem como tema Promoção no Ponto de Venda. Esta investigação tem como objectivo conhecer a percepção e comportamento de grupos de consumidores face a promoções no ponto de venda. O desenvolvimento deste projecto procurou encontrar resposta para os objectivos de investigação propostos através da realização de um inquérito por questionário. Toda a investigação empírica teve por base os resultados obtidos através de 156 questionários online a consumidores, maiores de 18 anos, de super e hipermercados e centros comerciais. Foi utilizada uma amostra por conveniência, para a qual foi enviado questionário online através de email e redes sociais. Realizou-se então este estudo e os resultados demonstraram que as promoções continuam a motivar o consumo e a despoletar a compra imediata e em maior quantidade. Estas conclusões são diferenciadas face às categorias de produto, com maior interesse por parte do consumidor em relação às promoções nos bens essenciais e moda, e face às tipologias de promoção, cuja preferência de promoção são as que têm incidência no preço. No nosso estudo encontramos quatro segmentos de consumidores, que de uma forma global registam auto percepção de consumidores inteligentes, que procuram com a promoções optimizar a relação qualidade preço, e que são pouco impulsivos no consumo. Concluímos que as promoções no ponto de venda são técnicas de marketing em que os gestores de marketing devem continuar a apostar pois é um factor critico de sucesso no incremento de vendas.

A qualidade de vida e a satisfação dos utentes em unidades de internamento da Rede Nacional de Cuidados Continuados Integrados (RNCCI)

RESUMO - Enquadramento: Com o aumento da Esperança Média de Vida, e o consequente envelhecimento generalizado da população portuguesa, envelhecer com boa saúde e com elevada qualidade de vida, onde as pessoas com mais de 65 anos tenham a possibilidade de expressar todas as suas potencialidades e manterem um papel ativo na sua vida e na sociedade, é vincadamente um dos maiores desafios da sociedade contemporânea. Desta forma, foi imposto à sociedade e aos sistemas de saúde, a criação de novas estratégias, que promovessem a reabilitação, a autonomia e a qualidade de vida dos idosos. Nesta linha, surgiu em Portugal a criação da Rede Nacional de Cuidados Continuados Integrados, combinando os cuidados de saúde com o apoio social adequado a esta população. Objetivos: Num primeiro objetivo, pretende-se avaliar os diferentes domínios da autoperceção de qualidade de vida de indivíduos com idade igual ou superior a 65 anos, que se encontrem em período de internamento nas diferentes tipologias de Unidades de internamento da RNCCI (Unidade de Convalescença, Unidade de Média Duração e Reabilitação e Unidade de Longa Duração e Manutenção), bem como o seu grau de (in) dependência, de risco de falha de auto-cuidado, e de risco de quedas. Como segundo objetivo propomo-nos a avaliar o grau de satisfação desses mesmos utentes, relativamente à equipa de profissionais de saúde e aos aspetos organizacionais e serviços prestados pela Unidade da RNCCI, onde se encontram internados. Por último, pretendemos averiguar a existência ou inexistência de relação entre as demais variáveis em estudo com a tipologia de Unidade de internamento onde o utente se encontra a receber cuidados. Métodos: O presente estudo é caraterizado como um estudo quantitativo, de caráter exploratório, e de índole descritivo-correlacional, que visa descrever fenómenos e, posteriormente, identificar e explorar possíveis relações entre variáveis. O estudo centrou-se em indivíduos, com idade igual ou superior a 65 anos, internados em Unidades de Cuidados Continuados da Rede Nacional de Cuidados Continuados Integrados, tendo sido efetuados dois questionários distintos: um de satisfação, e um segundo instrumento de perceção da qualidade de vida, denominado de EasyCare, estando este já cientificamente validado a nível internacional e nacional. Foi obtida uma amostra de 35 utentes.

What nourishes the spirit of adolescents in the classroom? : a qualitative study into the gateways of adolescents' souls /

This thesis investigated the question, "What nourishes the adolescent spirit in the classroom?" Action research was conducted by the teacher of 16 grade 8 participants. By undergoing Kessler's (2000) "Passages Program," the students participated in 6 sessions which exposed them to a holistic intrapersonal curriculum. Student journal responses were documented after each session. The action researcher also kept journal reflections after each session. Upon completion of the 6 sessions, a postinterview was conducted which posed the research question. The research found that the adolescent spirit gets nourished through encouragement by the teacher, peers, and parents. This increases their competency, which increases their confidence, and ultimately their self-esteem goes up, which affects their selfconcept. In addition, the role of the teacher permeates every aspect of what nourishes the adolescent spirit in the classroom. In addition to the encouragement of the student, how a teacher teaches plays a vital role. A holistic approach to teaching provided the best atmosphere for the adolescent. It promoted creativity and choice, which stimulated the spirit of the adolescent. By working from a holistic philosophy, the teacher/action researcher created an environment conducive to teaching the whole person, which ultimately nourished the participants' spirit. The research highlighted that in order for this type of environment to exist the teacher needs to make a conscious and deliberate effort to look within and develop their inner self before they can begin to promote this type of classroom for the adolescents they teach. When teachers and students develop an inner life together, they can begin to work in harmony to achieve an atmosphere where the teaching and learning environment becomes one seamless transaction. Only then can one's whole potential be realized.

Exploring exploration : career identity development and temperment /

Career identity exploration is a central component of the lives of undergraduate university students. Although students are encouraged to explore, it is unclear whether different methods of exploration are better suited for certain individuals. In the present study, quantitative data were collected to examine the relationship between shyness and various methods of exploration. Two hundred fifty-seven university undergraduate students (29 male), ranging in age from 17-25 years completed a 60-minute self-report questionnaire. Shyness, identity, identity distress, subjective dimensions of exploration (satisfaction with exploration, reasons for not exploring, helpfulness of exploration methods), foci of exploration (non-social, social, self, and environmental), approaches to exploration (breadth, depth), and moderating variables (social support, sociability) were measured. Shyness was positively correlated with moratorium (high exploration, low commitment) and uncorrelated with the other identity statuses. Shyness was also positively correlated with identity distress, and a predicted interaction between shyness and identity diffusion predicting career identity distress was supported. Shyness was negatively correlated with satisfaction with amount of exploration engaged in to-date. In addition, shyness was correlated with the likelihood of selecting too stressful and too anxiety provoking as reasons for engaging in less exploration than one would like. Expected relationships between shyness and beliefs about, and engagement in, various methods of exploration were largely non-significant. Exceptions to this were the negative correlations between shyness and engagement in social exploration, and beliefs about the helpfulness of social self-exploration, both of which were significant at a trend level. A predicted interaction between shyness and social support predicting total social exploration was supported, showing that high social support buffers the negative relationship between shyness and exploration; such a moderating relationship did not exist, however, between sociability, shyness and social exploration. Results suggest that although shy university students are engaged in career exploration, they are experiencing feelings of distress and dissatisfaction with their career identity exploration and development. Thus, to help shy students become successfiil in their exploration, it is important for counsellors, family members, and peers to be aware of the feelings the individuals are experiencing and help them reduce the anxiety and stress associated with the exploration process. One promising method, supported by the results in this study, is by encouraging shy individuals to explore with social support.

The storying of an educator: the power of living legacy /

"I began these pages for myself, in order to think out my own particular pattern of living, my own individual balance of life, work and human relationships." Lindbergh (1983) p.9. In this thesis, I use self-study research as I focus on the topic of living legacy. This is a personal story, using narrative methodology and method as a means of uncovering and naming life lessons learned. I write to gain insight into my interpretation of the concept of living legacy - what living legacy means to me and why this concept is significant to me - and how living legacy impacts the person that I am in the present. Using a narrative lens, I inquire into stories that connect me to my spirit, my gender, education and theology, through my living legacy lessons, and I seek the impact these stories hold for me in my life today. I utilize a variety of methods including personal journals, course work, and arts-based research experiences as I explore the connections to my emerging perceptions ofmy living legacy lessons. This thesis represents the beginning of a continuing journey of self-discovery. I take the journey in order to uncover hidden and ongoing lessons of living legacy and the impact they have on the student and educator that I am.

Exploring female graduate students' multifaceted and intersecting roles and identities in a complex educational milieu /

This qualitative phenomenological investigation explored six female Master of Education students' critical understandings of their identity and role negotiations, and their perceptions of environmental conditions that facilitated or impeded their identity explorations and negotiations within the institution. The interweaving of Feminist and Women's Development theories enabled the data to be examined under different, yet complementary, lenses. The data collection strategies included: four to five in-depth semistructured interviews, three take-home activities (involving identity mapping, object and metaphor identification, and strategy development), and the compilation of extensive interview notes as well as researcher reflections. The combination of a constant comparative method and a voice-centered method were used in tandem to analyze the data. Together they uncovered five emergent themes: (a) intricate understandings of key terms; (b) life-long learning and transformative pathways; (c) gender issues; (d) challenges, tensions, and possibilities; as well as (e) personal, professional, and educational implications. The findings underscored the possibility for both a singular static identity and dynamic multifaceted identities to exist in tandem, and the emergence of natural or logical identity intersections, as well as disjointed or colliding identity intersections. Ultimately, it is the continuous negotiation of internal and external spheres that contributes to the complexity and multidimensionality of graduate students' identities.

An exploratory study of nurses' perceptions of their action learning experience /

Each year, the College of Nurses of Ontario (CNO) requires all registered nurses and registered practical nurses in Ontario to complete a Reflective Practice learning activity. In doing so, nurses are expected to perform a self- assessment, identify a practice problem or issue, create and implement a personal learning plan, and evaluate the learning and outcomes accomplished. The process and components of CNO's Reflective Practice program are very similar to an Action Learning activity. The purpose of this qualitative research was to explore the perceptions of 1 1 nurses who completed at least 1 Action Learning activity. Data analysis of their comments provided insight into their perceptions of the Action Learning experience, perceptions of the negative and positive characteristics of various activities within the Action Learning process, and perceptions of barriers or challenges within this experience. The author concluded that participants perceived their Action Learning activities to be a positive experience because the process focused on practice problems and issues, enhanced thinking about practice problems, and achieved practice-relevant outcomes. However, the results indicated that self-directed learning and journal writing were difficult activities for some participants, and some experienced negative emotional responses during reflection. The research concluded that barriers to implementation of Action Learning include a lack of understanding of the process and a perceived lack of support from employers.

Paradigms and prisons: a narrative of translation and transformation : my hero's journey from "at-risk" youth to teacher/learner in a jail setting /

All life is suffering. Life is the pursuit ofhappiness. These are two foundational Buddhist dictums that, in their simplicity, I have entirely misunderstood regarding their depth, misreading them as contradictory. Indeed, my superficial interpretations led me to Thoreau's life ofquiet desperation and deep depression. We come to know and bring understanding to our lives by storying them. My own Hero's Journey, the path from my egoic selftoward the universal Self, can be understood as the resultant translations and transformations. Inevitably each of us is involved in such a story, though most are unaware of the stages along our own Hero's journey. ' Narrative honours writing as a means of knowing. The contemplative reflection allows insight into our imprisoning paradigms, beliefs, behaviours, and blind spots. My research revisits and explores nodal experiences along my Hero's Journey through 4 categories: self, society, soil, and Self. While the value of this process of narrative inquiry lay in its ability to come to know and understand one's self, perhaps its greater value is of a more universal nature. My inquiry, while adding to the body of academic educational narrative literature, may also illuminate a path to educators, students, and all interested, encouraging a response to the call of their own Hero's journey. I am a teacher/learner in a jail setting, working with youth between the ages of 12 and 18 who have committed crimes such as armed robbery, assault, rape, and murder. As this thesis follows my continual development from egoic self/teacher/learner to universal Self/Teacher/Learner, it also enables me to both consciously and unconsciously open the ways in which I expand my care, compassion, and love to work with at-risk youth.

Construing social dimensions of personality development: nurses as educators

A convenience sample of twenty registered nurses was recruited from two' general hospitals and two community college nursing schools. Kelly's (1955) Personal Construct Theory provided the theoretical framework to discover how nurses perceived themselves as educators. The nurses completed a self-administered Self-Perception Inventory (Soares, 1983) to determine their perception of self as nurse and ideal self as nurse. In an interview, each of the nurses constructed a rank-order repertory grid adapted from Kelly's (1955) Role Repertory Construct Test. Twelve constructs derived from the Self-Perception Inventory (Soares, 1983) were ranked according to a list of ten elements common to a teaching situation. Rank order correlations among the constructs were determined with Spearman's rho. Using a dependent samples t-test, significant differences were found between perceptions of current and ideal self for staff nurses. Significant differences were also found between nurse educators' perceptions of self and ideal self as nurse. No significant differences were determined in perceptions of self as nurse and ideal self as nurse between the staff nurse and nurse educator groups with an independent samples t-test. However, observations of single constructs revealed that although several constructs are shared between the groups in the perception of self in a teaching situation, both groups hold constructs that operate exclusively in their separate domains. The nature and strength of the relationships between the common and unique constructs are different for each group. Nurses I self-perceptions appear to be influenced by the historical development of nursing, role socialization during nursing education, social expectations and gender issues in the health care system.

Values and the classroom teacher

This is a descriptive study of elementary school teachers' perceptions of values transmitted in classrooms. Through circulation of a survey to teachers in Public and Separate Schools in the "Golden I-Iorseshoe" distt-ict of SOLtthern Ontario (e}{clLtding Toronto), it was found that teachers do see themselves as promoting values which tend to be conceptual or knowledge-based and receptive and pertain to self-perception and personal growth. They also show a tendency t.o Lise nlore conceptL\al teachi ng strategies SLieri as discussiona The respondents had no clear opinion regarding student disposition toward values but did feel very influential in developing that disposition.

Pausing at the river's edge : a narrative inquiry into the practice of a reading teacher /

In this narrative self-study I retell and connect the stories ofmy personal journey with literacy from childhood to the present. I use narrative as both methodology and method as I story my life experiences and my personal encounters with literacy. The heart ofmy reflections comes from the pages of personal journals written and storied over many years of trying to make meaning of powerful literacy experiences in my life. Now, in going back through the stories and reconstructing meaning, I make connections between the memories along the journey and the place from which I now tell my story. The interpretations I construct give voice to beliefs 1 have lived by and illuminations to moments in time that I have come to see with new eyes as I have engaged in this inquiry. The journey and self-reflection within the pages of this inquiry provide understanding of the driving force behind my personal passion for literacy. I am better able to understand my motivations and share the stories that validate my personal and professional path through time.

Teacher attitudes and the emotionally-behaviourally disordered middle school student

Inclusionary practices prescribe that chl1dren, regardless of exceptional1ty shall benef1t from receiv1ng educational serv1ce 1n the context of the regular class sett1ng. The result1ng el1minat1on of separate spec1al classes could be v1ewed as an econom1c advantage. In point of fact, many school boards and d1str1cts 1n both Canada and the United States are mov1ng towards 1mplementat1on of inclusionary practice, possibly for the above stated reason. Regardless, 1nclusion as 1t relates to the emot1onally/behav1ourally disordered youth in our school systems may not be successful. Regular educat ion teachers may not be prepared profess1onally or personally to deal w1th this very special student population. Th1s study focused on teacher attitude 1n this regard. As well, poss1ble factors that may lead to successful 1nclusion of these students are examined. Of these, teacher exper1ence, educat10n spec1f1c to the d1sab1l1ty of emot1onal/behavioural d1sordered comb1ned w1th teacher self-perception of success appear to hold the greatest promise. In view of these findings, recommendat1ons are made for professional pract1ce and future research d1rect1ons.
