Thesis advisor: Alyssa Goldman / People’s needs for social engagement vary over the life course. Social engagement for individuals residing in memory care facilities is an important topic to research because this population benefits greatly from active participation in the communities in which they reside. This study examines the following research questions: To what extent does the facility in which adults with Alzheimer’s disease reside impact their social ties? How do the facilities differ in facilitating social engagement? I interviewed ten memory care facility employees across seven facilities in Massachusetts and found patterns in visitation for family members and friends of Alzheimer’s residents and social engagement for residents in memory care. Individual factors that affect visitation include family dynamics and disease progression. Structural factors that affect visitation include geographic location and religion. These findings are useful to inform policy and recognize increased opportunities for social engagement as an opportunity for facilities to slow disease progression. / Thesis (BA) — Boston College, 2023. / Submitted to: Boston College.

Contudo, o uso destes primatas implica numa série de questões éticas, incluindo as condições de seu cativeiro e os potenciais fatores da experimentação que podem acarretar dor, injúrias e estresse, interferindo diretamente no bem-estar do animal. O presente trabalho buscou avaliar as respostas comportamentais e endócrinas de sagüis-de-tufos-pretos (Callithrix penicillata) cativos, machos e fêmeas, frente à técnica de enriquecimento ambiental do tipo alimentar (tubo) e isolamento visual (barreira). As observações foram realizadas em uma amostra de seis fêmeas e seis machos adultos de C. penicillata mantidos no Centro de Biologia da Reprodução da Universidade Federal de Juiz de Fora, Minas Gerais, Brasil. As observações comportamentais foram realizadas antes, durante e depois da aplicação da técnica de enriquecimento, no período da manhã, iniciando entre 10 e 11 horas. A avaliação endócrina foi realizada através da mensuração dos níveis de cortisol presente nas amostras fecais dos animais. Tais análises foram realizadas no Laboratório de Dosagens Hormonais da Universidade Federal do Rio Grande do Norte. Para o enriquecimento alimentar foram encontradas alterações significativas que indicam que este foi eficaz reduzindo comportamentos de alimentação durante a exposição ao enriquecimento e reduzindo a agitação. Para este tipo de enriquecimento os machos se mostraram comportamentalmente mais reativos que as fêmeas e não houve diferença significativa para os níveis de cortisol. Com a utilização do enriquecimento social, foi verificado o conflito gerado com a proximidade entre indivíduos do mesmo sexo, sendo a fase com a barreira a que menos apresentou comportamentos indicativos de estresse, e as fêmeas apresentaram os menores valores para o cortisol. No confronto dos dados de machos e fêmeas, estas se mostraram mais reativas à presença de outras fêmeas, possivelmente pelo fato que sua estratégia reprodutiva ser reflexo do status social. Para os machos o isolamento foi um fator de estresse, uma vez que tiveram maior concentração de cortisol. / Non-human primates are often used in behavioral studies and in biomedical research as a model mainly because their phylogenic proximity to human beings. However, the use of non-human primates in researches implies in many ethical issues, including the captivity conditions and the potential aspects of the procedures that may cause pain, injuries and stress which can interfere with their welfare. The present research intended to analyze the behavioral and endocrine responses of six males and six females of captive black-tuffed marmosets (Callithrix penicillata) to a feeding (tube) and a visual isolation (barrier) environmental enrichment techniques. The animals belong to the colony maintained by Centro de Biologia da Reprodução of Universidade Federal de Juiz de Fora, in Juiz de Fora, Minas Gerais state, in Brazil. The behavior and hormonal data were collected before, during and after the exposure to environmental enrichment. The hormonal analysis of fecal cortisol was performed in the Laboratorio de Dosagens Hormonais of the Universidade Federal do Rio Grande do Norte. During the exposure to the feeding enrichment technique – FASE II, it was observed a decrease in movement and in ingestion of the regular diet by the animals. Besides, in this experiment, the male marmosets were more reactive than the females and no significant differences on cortisol levels were detected. Using the social enrichment (a visual barrier between the cages), it was verified the existence of conflicts between close same-sex animals, which decreased cortisol when the barrier was used. In this case, the marmoset females were more reactive to the enrichment probably because they compete to reproductive as a consequence of social dominance. For males the isolation seems to be a stressful situation since they increase cortisol on this situation.
