The relationship between a retention program and the persistence and graduation rates of first-generation low-income students at an urban, public university

The purpose of this study was to examine the relationship between participation in a retention program designed to promote academic and social integration and the persistence rates of first generation, low-income college students at an urban, public multiethnic university. Archival data were collected from the university’s Office of Institutional Research and the retention program office and included SAT/ACT scores, GPA, gender, ethnicity, and program participation data. A total of 292 first-generation, low-income students who were admitted to the university in the summer of 1999 were identified for the study. A group of 166 students were selected for the comparison group because they had not participated in the retention program; 126 students had participated in the retention program. ^ Three major research questions guided this study: (a) Are there differences in persistence rates and other academic characteristics of underprepared, low-income, first generation college students who participate and do not participate in the retention program?; (b) Does involvement in the retention program predict student persistence of first generation low-income, underprepared students?, and (c) Can predictors of GPA be identified for students in the retention program using program and descriptive variables? ^ A series of logistic regression analyses were conducted to assess the relationship between various retention services and the persistence and graduation rates of participants. The results showed that there were statistically significant relationships between participation and non-participation in the retention program and having higher GPAs and higher graduation and persistence rates. Of the four program features, participation in tutoring, workshops, and social events were found to be predictors of graduation. College GPA was also found to be a predictor of graduation for all students. The results also showed that women were more likely to graduate than men.^

Predicting the in-term persistence of community college English-as-a-second-language students

The English-as-a-second-language (ESL) community college student population has increased notably in the past decade, but a decreasing number of these students are completing courses, programs, or degrees (Erisman & Looney, 2008). These students come to college with unique background experiences, and once in college, deal with challenging linguistic, academic, and social integration issues. Though they are not linguistically homogenous, and they do not have a common purpose, ESL students share the common goal of attending community college to learn to speak English (Szelényi & Chang, 2002). Course completion is a primary measure of progress toward that goal, and is therefore an issue of concern for both ESL students and community colleges, which continue to be the access point for language-minority students progressing into higher education (Laden, 2004).^ The purpose of this study was to investigate the factors that predict in-term persistence of community college ESL students. A mixed methods research design consisting of two phases was utilized, and participants in this study were ESL students enrolled in a large community college in south Florida. Phase 1 students completed the Community College ESL Student Questionnaire (CCSEQ), which collected demographic data and data on entry characteristics, academic integration, and social integration. Discriminant and descriptive analyses were used to report the data collected in Phase I. Phase 2 students were a matching cohort of completing and non-completing students who participated in semi-structured interviews at the end of the term. Data collected in the interviews were analyzed thematically, using a constant comparative method as described by Glaser and Strauss (1967).^ Students’ self reported demographic data, background characteristics, goal commitment, and integration factors on the CCSEQ showed no significance between the students who completed the term and the students who did not complete the term. However, several differentiating themes emerged from the interview data, which indicated differences in goal commitment and integration between the two groups. The focus of non-completers on getting good grades rather than completing the course, and the commitment of completers to the goal of finishing the class in order to go forward, both raise questions for future research studies.^

The Influence of Psychological Predictors and Cognitive Behavioral Stress Management Intervention on Antiretroviral Therapy (ART) Adherence Among HIV-Positive Female Haitian Alcohol Users

Purpose: Over half the HIV-infected persons in the Caribbean, the second most HIV-impacted region in the world, live in Haiti. Using secondary data from a parent study, this research assessed the effects of psychological and social factors on antiretroviral therapy (ART) adherence among Haitian, HIV-positive, female alcohol users. Theoretical Foundation and Research Questions: Using the Theory of Planned Behavior/Reasoned Action and the Information, Motivation, Behavior skills model as guiding theoretical frameworks, the study examined the effectiveness of an adapted cognitive behavioral stress management (CBSM-A) intervention in improving ART adherence. The effect of psychological factors (depression, anxiety, beliefs about medicine, and social support), social factors (stigma, relationship status, and educational attainment), and alcohol on adherence to ART was assessed. Methods: The sample consisted of 116 female ART patients who were randomly assigned to the CBSM-A intervention or the wait-list control group. Participants completed intervention sessions as well as pre- and post-test assessments. Analyses of variance, t-tests, and point biserial correlations were used to test hypotheses. Results: Surprisingly, ART adherence rates significantly decreased for both groups combined [F (1, 108) = 8.79, p = .004]; there was no significant difference between the intervention and control groups with regard to the magnitude of change between baseline and post assessment. On average, depression decreased significantly among participants in the CBSM-A group only [(t (62) = 5.54, p < .001)]. For both groups combined, alcohol use significantly decreased between baseline and post-assessment [(F (1, 78) = 34.70, p < .001)]; there was no significant difference between the intervention and control groups with regard to the magnitude of change between baseline and post-assessment. None of the variables were significantly correlated with ART adherence. Discussion: Adherence to ART did not improve in this sample, nor were any of the variables significantly associated with adherence. The findings suggest that additional supportive and psychological services may be needed in order to promote higher adherence to ART among HIV-positive females. More research may be needed on this sample; a focus on mental health issues, partner conflict, family and sexual history may allow for better targeting and more successful interventions.

Prevalência e fatores associados à alteração vocal em idosos institucionalizados com capacidade cognitiva preservada

Voice disorders (VD) in the elderly can interfere negatively in communication, emotional well-being and quality of life, conditions that correspond to greater exposure to illness and social isolation bringing consequent economic impact for the health system. It is assumed that institutionalized confinement, weakness and morbidity associated to nursing home (NH) contribute to transform VD an especially prevalent condition in institutionalized elderly, including those without cognitive impairment. Thus, the aim of this study was to determine the prevalence and associated factors of VD in NH elderly residents without cognitive impairment. There is no epidemiological diagnostic instruments of VD for elderly populations, so the first step of this study was dedicated to prepare and analyze the psychometric properties of a short, inexpensive and easy to use questionnaire named Screening for Voice Disorders in Older Adults (Rastreamento de Alterações Vocais em Idosos—RAVI). The methodological procedures of this step followed the guidelines of the Standards for Educational and Psychological Testing and contemplated validity evidence based on test content, based on response processes, based on internal structure and based on relations with other variables, as well as reliability analysis and clinical consistency. The result of the validation process showed that the RAVI final score generate valid and reliable interpretations for the epidemiological diagnosis of VD in the elderly, which endorsed the use of the questionnaire in the second stage of the study, performed in ten NH located in the city of Natal, Rio Grande do Norte. At this stage, data from socioeconomic and demographic variables, lifestyle, general health conditions and characterization of the institution were collected. It was performed a bivariate analysis and it was calculated the prevalence ratio as a magnitude association measure, with a confidence interval of 95%. The variables with p-value less than 0.20 were included in the multiple logistic regression model that followed the Forward selection method. The odds ratio found in the multivariate model was converted into prevalence ratio and the level of significance was 5%. The sample consisted of 117 subjects with predominance of females and average of 79.68 (± 7.92) years old. The prevalence of VD was 39.3% (95% CI: 30.4-48.1%). The multivariate model showed statistically significant association between VD and depressive symptoms, smoking for a year or more and selfreported hearing loss. In conclusion, VD is a prevalent health condition in NH elderly residents without cognitive impairment and is associated with factors involving psychosocial, lifestyle and communicative disability that require attention of managers and professionals involved with NH environment. Strategies to encourage communication and social integration, actions to combat smoking and minimizing the effects of hearing loss could stimulate the physical well-being, emotional and mental health of institutionalized elderly population, contributing to the vocal and communicative maintenance, a more effective social inclusion and better overall health condition.

Health Knowledge, Attitudes, and Practices among Street Children in LMICs

Background: Worldwide, it is estimated that there are up to 150 million street children. Street children are an understudied, vulnerable population. While many studies have characterized street children’s physical health, few have addressed the circumstances and barriers to their utilization of health services.

Methods: A systematic literature review was conducted to understand the barriers and facilitators that street children face when accessing healthcare in low and middle income countries. Six databases were used to search for peer review literature and one database and Google Search engine were used to find grey literature (theses, dissertations, reports, etc.). There were no exclusions based on study design. Studies were eligible for inclusion if the study population included street children, the study location was a low and middle income country defined by the World Bank, AND whose subject pertained to healthcare.

In addition, a cross-sectional study was conducted between May 2015 and August 2015 with the goal of understanding knowledge, attitudes, and health seeking practices of street children residing in Battambang, Cambodia. Time location and purposive sampling were used to recruit community (control) and street children. Both boys and girls between the ages of 10 and 18 were recruited. Data was collected through a verbally administered survey. The knowledge, attitudes and health seeking practices of community and street children were compared to determine potential differences in healthcare utilization.

Results: Of the 2933 abstracts screened for inclusion in the systematic literature review, eleven articles met all the inclusion criteria and were found to be relevant. Cost and perceived stigma appeared to be the largest barriers street children faced when attempting to seek care. Street children preferred to receive care from a hospital. However, negative experiences and mistreatment by health providers deterred children from going there. Instead, street children would often self treat and/or purchase medicine from a pharmacy or drug vendor. Family and peer support were found to be important for facilitating treatment.

The survey found similar results to the systematic review. Forty one community and thirty four street children were included in the analysis. Both community and street children reported the hospital as their top choice for care. When asked if someone went with them to seek care, both community and street children reported that family members, usually mothers, accompanied them. Community and street children both reported perceived stigma. All children had good knowledge of preventative care.

Conclusions: While most current services lack the proper accommodations for street children, there is a great potential to adapt them to better address street children’s needs. Street children need health services that are sensitive to their situation. Subsidies in health service costs or provision of credit may be ways to reduce constraints street children face when deciding to seek healthcare. Health worker education and interventions to reduce stigma are needed to create a positive environment in which street children are admitted and treated for health concerns.

Literatura en el espacio público : Rivas y su obra: un punto de inflexión en la recuperación de la memoria histórica

Tras una revisión diacrónica del tratamiento del tema de la guerra civil en la narrativa gallega, el artículo analiza la función performativa que en ese contexto han desempeñado una serie de obras narrativas de Manuel Rivas y su eficacia como factores de legitimación y dinamización del proceso de recuperación de la memoria histórica. Como conclusión se propone considerar a Rivas como un emprendedor de la memoria (Jelin) y sus obras como 'lieux de memoire' (Nora) por su condición de artefactos culturales de integración social.

Football Talk: Sociological Reflections on the Dialectics of Language and Football

The paper examines the relationship between football and language from a sociological point of view. This has often been couched in negative terms but the paper argues that such a view distorts the majority of ‘Football Talk’. The discourse surrounding football within everyday interactions is often positive and integrative. ‘Football Talk’ acts as a lingua franca amongst football supporters. This language code is therefore both inclusive and exclusive.

‘New’ migrant identities: unravelling opportunities and restrictions

Labour and capital mobility from globalisation has given rise to significant increases in the reliance of migrant labour in established gateways, but also in new migration destinations. Many aspects of migrant incorporation in new migration destinations have received some attention, not least regarding employer and employee relations. Less attention has been focused on the construction of migrant as a marker of identification, although identities, particularly regarding gender and ethnicity, in the workplace have received considerable attention. This article aims to illuminate knowledge on how migration produces social change thereby responding to a call from Batnitzky et al. (2009, p. 1290) for additional attention on what ‘the practical and symbolic effects of migration are as people move across different structures and institutions of social control….’ Mindful of Goffman’s (1969, 1983) emphasis on individual interactions and experiences, it examines what it means to be a migrant in terms of everyday encounters and experiences. It investigates the array and interplay of internal and external processes that create migrant identities and the implications of this for social integration.

The paper argues that one of the paradoxes of globalisation, and of the associated increased levels of migrant labour, is the construction of the migrant identity that ultimately impedes social integration. It shows how the application of migrant identity (internally and externally) bestows a particular status that affects (options for) individual behaviour and subsequent actions and outcomes. The paper argues that while migrants value the migrant identity status because of the benefits that it brings, this status can also cause high levels of dissatisfaction among migrants and it can exclude migrants from wider benefits of full citizenship. Migrants have individual identification processes, but external forces, including social structures and institutions, also affect migrant identity. These forces help to shape individual expectations and standards, contributing to identity interruption and dissonance.

The paper is structured as follows: it uses social identity theory as a means of understanding what it is to be a ‘migrant’ in a new destination, while simultaneously recognising the inevitability of this generic label - migrants are an extremely heterogeneous group, made up of individuals with different experiences, values and so forth. The analysis considers the significance of context and of social interactions, thus paying attention to how identity is constructed and performed by the individual and also assigned by others. Empirical evidence is used to examine how having a migrant status affects individual prospects. The paper evaluates the extent to which patterns and processes of migration present an opportunity for social change, positive or negative.

Récits du vieillir « actif » et de la citoyenneté au quotidien : l’expérience des femmes aînées au Québec

Taken as a policy framework, active aging ranks high on most supranational bodies’ agenda. The new political economy of aging portrays “active” citizenship amongst seniors as a key challenge for the years to come. Our research focuses on, first, elderly women’s everyday ‘active’ practices, their meaning and purpose, in the context of Quebec’s active aging policy framework; and second, their day-to-day practical citizenship experiences. Informed by discourse analysis and a narrative approach, the life stories of women 60 to 70 years of age allowed for the identification of a plethora of distinctive old age activity figures. More specifically, four activity figures were identified by which respondents materialize their routine active practices, namely: (1) paid work; (2) voluntary and civic engagement; (3) physical activity; and (4) caregiving. Set against Quebec’s active aging policy framework, these patterns and set of practices that underpin them are clearly in tune with government’s dominant perspectives. Respondents’ narratives also show that active aging connotes a range of ‘ordinary’ activities of daily living, accomplished within people’s private worlds and places of proximity. Despite nuances, tensions and opposition found in dominant public discourse, as well as in active aging practices, a form of counter-discourse does not emerge from respondents’ narratives. To be active is normally the antithesis of immobility and dependence. Thus, to see oneself as active in old age draws on normative, positive assumptions about old age quite difficult to refute; nevertheless, discourses also raise identity and relational issues. In this respect, social inclusion issues cut across all active aging practices described by respondents. Moreover, a range of individual aims and quests underpin activity pattern. Such quests express respondents’ subjective interactions with their social environment; including their actions’ meaning and sense of social inclusiveness in old age. A first quest relates to personal identity and social integration to the world; a second one concerns giving; a third centers on the search for authenticity; whereas the fourth one is connected to a desire for freedom. It is through the objectivising of active practices and related existential pursuits that elderly woman recognize themselves as active citizens, rooted in the community, and variously contributing to society. Accordingly, ‘active’ citizenship experiences are articulated in a dialogic manner between the dimensions of ‘doing’, ‘active’ social practices, and ‘being’ in relation to others, within a context of interdependence. A proposed typology allows for the modeling of four ‘active’ citizenship figures. Overall, despite the role played by power relations and social inequality in structuring aging experiences, in everyday life ‘old age citizenship’ appears as a relational process, embedded in a set of social relations and practices involving individuals, families and communities, whereby elderly women are able to express a sense of agency within their social world.

Famílias Unipessoais Idosas: um estudo das redes sociais pessoais de idosos que vivem sós

Objetivos: O presente estudo tem como objetivo analisar as características estruturais, funcionais e relacionais-contextuais das redes sociais pessoais de famílias unipessoais idosas. Metodologia: Utilizámos para recolha de dados um questionário para caracterizar sociodemograficamente a amostra, o Instrumento de Análise da Rede Social Pessoal (versão para idosos) (IARSP-Idosos) (Guadalupe, 2010; Guadalupe e Vicente 2012) e a escala de solidão UCLA (Neto, 1989). Participantes: A amostra é constituída por 567 indivíduos com média de idades de 75,53 anos, maioritariamente do sexo feminino (63,0%; n = 357). Predominam os sujeitos casados (53,7%; n = 304), com filhos (87,8%; n = 498) e em situação de coabitação (n = 450; 79,4%). Contudo, 20,6% (n = 117) vivem sós, constituindo as famílias unipessoais. Resultados: As redes sociais dos idosos têm em média 7,99 elementos, predominantemente familiares (M = 76,89%). Os participantes percecionam um nível elevado de apoio por parte das suas redes. São redes coesas, pouco dispersas e os contactos entre os elementos são frequentes. As mulheres, os indivíduos solteiros, viúvos ou divorciados e os idosos sem filhos têm uma maior probabilidade de viverem sós (p < 0,05) e estes apresentam uma maior probabilidade de necessitar de apoio social formal (p < 0,05). As famílias unipessoais, quando comparadas com os que não vivem sós, apresentam um maior número de campos relacionais e maior proporção de relações de amizade e de vizinhança (p < 0,05). Têm menor perceção de apoio material e instrumental, informativo, companhia social, acesso a novos vínculos e reciprocidade de apoio (p < 0,05). Além disso, referem menor frequência de contactos e uma maior dispersão geográfica (p < 0,05). Nas famílias unipessoais, observou-se a existência de correlações negativas significativas (p < 0,05) entre a percepção de solidão e o tamanho da rede, a proporção das relações familiares na rede, o apoio emocional e informativo e a reciprocidade de apoio. CONCLUSÃO: Os idosos com famílias unipessoais percecionam menor apoio por parte das suas redes, tendo uma maior propensão à solidão. É fundamental, ao longo do ciclo vital, promover a quantidade e qualidade dos vínculos, no sentido de manter a efetividade do suporte das redes mesmo quando se vive só. / Objectives: The present study aims to analyze the structural, functional and relational-contextual characteristics of older single-person households. Methodology: We used as instruments a questionnaire to evaluate sociodemographic data, the Instrumento de Análise da Rede Social Pessoal (version for elderly people: IARSP-Idosos) (Guadalupe, 2010; Guadalupe e Vicente 2012) and the UCLA Loneliness Scale (Neto, 1989). Participants: The sample consists of 567 individuals with an average age of 75.53 years, mostly females (63.0%; n = 357). There is a predominance of married individuals (53.7%; n = 304) with children (87.8%; n = 498). Older people live mainly in cohabitation (n = 450; 79.4%), however 20.6% oh them live alone, constituting one-person households. Results: The elderly personal social networks have 8 elements, on average, with a predominance of family relationships (M = 76.89%). The participants perceived a high level of support from their networks. In general the networks are cohesive, with low dispersion and have frequent contacts. The women, single, widowed or divorced and childless elderly are more likely to live alone (p < 0.05) and to need social services support (p < 0.05). The single-person households, compared with those who do not live alone, have a greater number of relational fields and a higher proportion of friendships and neighborhood relations (p < 0.05). They have a lower perception of material and informative support, social company and acess to new ties and reciprocal support (p < 0.05). They also refer lowest frequency of contacts and a wider geographical dispersion (p < 0.05). In single-person households there was a negative significant correlation between the perception of loneliness and the social network size, the proportion of family relationships in the network, emotional and informational support and reciprocal support. Conclusions: The elderly single-person households perceived less support from their networks and a greater propensity to loneliness. It is critical to promot the quality of ties, rather then their quantity, throughout the life cycle, in order to maintain the network effectiveness even when the person lives alone.

A Família nas Redes Sociais Pessoais de Idosos

Objetivos: Analisar as caraterísticas sociodemográficas e das redes sociais pessoais dos idosos de acordo com a composição das redes centrada na família. Metodologia: Para caraterizar as redes sociais pessoais utilizámos o Instrumento de Análise da Rede Social e Pessoal – Idosos (IARSP-idosos) (Guadalupe, 2010; Guadalupe e Vicente, 2012) e um questionário para descrever sociodemograficamente a amostra. Participantes: A amostra é constituída por 567 idosos (M = 75,53 anos), com predominância do sexo feminino (64,1%). A maioria é casada (53,8%) e detém a 4ª classe (51,3%). Os participantes, na sua maioria, têm filhos (87,8%) e não vivem sós (79,4%). Resultados: As redes são compostas em média por 8 elementos, dominadas por laços familiares (M = 76,90%). São redes coesas, com relações interpessoais duradouras, com pouca dispersão geográfica e elevada frequência de contactos. O apoio percebido nas redes é sobretudo emocional e informativo. Quanto à sua composição, 43,7% dos idosos têm uma rede exclusivamente familiar, 53,4% redes com família e outros campos relacionais e apenas 2,8% apresentam redes sem família. Os idosos com 76-85 anos, casados e com agregado familiar numeroso têm maior probabilidade de pertencer a redes exclusivamente familiares. Os idosos mais jovens e divorciados tendem a pertencer a redes mais diversificadas, enquanto as mulheres e os indivíduos solteiros e sem filhos têm maior probabilidade de não ter laços familiares nas suas redes, compensando a sua ausência com relações de amizade e de vizinhança. As redes exclusivamente familiares estão associadas a maior perceção de apoio emocional, material e instrumental, companhia social e reciprocidade de apoio. As redes com família e outras composições caraterizam-se por ter mais elementos e uma maior dispersão geográfica. As redes sem família são as mais reduzidas e são normalmente homogéneas para o género feminino e a nível etário, no grupo idoso. Conclusões: Fica patente o papel central das famílias nas redes e no apoio informal. Contudo, será essencial potenciar a diversificação e manutenção dos vínculos promovendo o acesso a novos contactos ao longo de todo o ciclo vital, de forma a garantir uma rede social pessoal diversificada e efetiva, em vínculos e recursos, que complemente as necessidades e favoreça o bem-estar da pessoa idosa. / Objectives: To analyze the sociodemographical and personal social networks characteristics of the elderly according to the composition of the networks centered on the families. Methodology: For characterizing the personal social networks we used the Instrumento de Análise da Rede Social Pessoal (IARSP-Idosos) (Guadalupe, 2010; Guadalupe e Vicente, 2012) and for sociodemographic characteristics we used a questionnaire. Participants: The sample consisted of 567 elderly (M = 75.53 years), mainly female (64.1%). The majority are married (53.8%) and have the 4th grade (51,3%). Overall the participants have offspring (87.8%) and do not live alone (79.4%). Results: On average, the networks have 8 elements, mostly relatives (M = 76.90%). The networks are cohesive, long-lasting, have a low geographical spread and we observed a high frequency of contacts. The networks provide mostly emotional (M = 2.64) and informative support (M = 2.37). Regarding its composition, 43.7% of the elderly have an exclusively family network, 53.4% have networks with family members and other relational fields and only 2.8% have no relatives in their networks. The elderly whose age is between 76-85 years, married and with a large household are more likely to belong to exclusively family networks. Younger and divorced elderly tend to belong to more diverse networks, as women and individuals unmarried and without offspring are more likely to do not have family bounds in their networks, with a higher proportion of friends and neighbors. Exclusively family networks are associated with greater perception of emotional, material and instrumental support, social company and reciprocal support. Networks with family and other fields are characterized by having more elements and a greater geographical spread. The social networks without family are smaller and are usually homogeneous for female gender and age, in the elderly group. Conclusions: The role of families in providing informational support is clear. However, it will be essential to enhance the diversification and maintain ties that promote access to new contacts throughout our entire life, to ensure a diversified social network that will be effective in bonds and resources that complement the needs and encourages the well-being of the elderly.

An exploratory study of orthoptic student satisfaction in a blended learning environment

Purpose: To describe orthoptic student satisfaction in a blended learning environment. Methods: Blended learning and teaching approaches that include a mix of sessions with elearning are being used since 2011/2012 involving final year (4th year) students from an orthoptic program. This approach is used in the module of research in orthoptics during the 1 semester. Students experienced different teaching approaches, which include seminars, tutorial group discussions and e-learning activities using the moodle platform. The Constructivist OnLine Learning Environment Survey (COLLES ) was applied at the end of the semester with 24 questions grouped in 6 dimensions with 4 items each: Relevance to professional practice, Reflection, Interactivity, Tutor support, Peer support and Interpretation. A 5-point Likert scale was used to score each individual item of the questionnaire (1 - almost never to 5 – almost always). The sum of items in each dimension ranged between 4 (negative perception) and 20 (positive perception). Results: Twenty-four students replied to the questionnaire. Positive points were related with Relevance (16.13±2.63), Reflection (16.46±2.45), Tutor support (16.29±2.10) and Interpretation (15.38±2.16). The majority of the students (n=18; 75%) think that the on-line learning is relevant to students’ professional practice. Critical reflections about learning contents were frequent (n=19; 79.17%). The tutor was able to stimulate critical thinking (n=21; 87.50%), encouraged students to participate (n=18; 75%) and understood well the student’s contributions (n=15; 62.50%). Less positive points were related with Interactivity (14.13±2.77) and Peer support (13.29±2.60). Response from the colleagues to ideas (n=11; 45.83%) and valorization of individual contributions (n=10; 41.67%) scored lower than other items. Conclusions: The flow back and forth between face-to-face and online learning situations helps the students to make critical reflections. The majority of the students are satisfied with a blended e-learning system environment. However, more work needs to be done to improve interactivity and peer support.

Erosão dentária associada a distúrbios alimentares

Os distúrbios alimentares traduzem-se em comportamentos, quer pela falta, quer pelo excesso da ingestão de alimentos, sendo a anorexia nervosa e a bulimia as que mais frequentemente se verificam na população. O crescente aumento destes distúrbios, nomeadamente a obsessão pelos corpos magros, está relacionada com o impacto que os media têm na sociedade, uma vez que a magreza é vista como mecanismo de atracção sexual e de integração social. O diagnóstico das desordens alimentares não é fácil de ser efectuado, dado que os sinais são muitas vezes omitidos/ocultados pelos indivíduos. Os médicos dentistas podem ter um papel importante na sua detecção, dadas as manifestações precoces das alterações alimentares na cavidade oral. Há diversos sintomas comuns aos dois distúrbios alimentares como a erosão dentária, a hipersensibilidade dentinária, a hipertrofia das glândulas salivares e consequente hipossalivação, a cárie dentária, a doença periodontal, as mucosites, a candidíase oral e a queilite angular. Resultante do vómito induzido, há o aporte de ácido proveniente do conteúdo gástrico que induz alterações estruturais do esmalte e dentina, facilitando o processo de desgaste erosivo. Os fenómenos erosivos são uma das manifestações orais mais evidentes dos distúrbios alimentares. O conhecimento dos sinais, sintomas e da forma de evolução da erosão dentária, é imprescindível, e acaba por diferenciar a atuação profissional que possibilita um diagnóstico eficaz e o tratamento correto. A elaboração desta dissertação tem como objectivo reforçar a informação sobre estes fenómenos para que possam ser mais eficazmente prevenidos, diagnosticados e controlados/tratados. Para tal efectuou-se uma pesquisa na B-On, Medline/PubMed, sciELO, RCAAP e em livros, de informação válida sobre o tema. Interpôs-se limitação temporal e usaram-se as seguintes palavras-chave na seleção de artigos: “Dental erosion”, “Erosive wear”, “Anorexia”, “Bulimia”, “Eating disorders”.

Derby Adult Learning Service case study

Case study on how peer support tutor service leads to embedded use of technology in curriculum activities
