Clostridium beijerinckii is a spore-forming, obligate anaerobe that is capable of producing butanol, acetone and isopropanol. These industrial chemicals are traditionally known as solvents. The regulation of solventogenic fermentation is linked to the onset of sporulation, so that by the time the organism begins to produce solvents, it is also entering into spore formation and metabolic slowdown. The goal of this research project was to study the effect of placing the solvent-production genes from C. beijerinckii under the control of constitutive promoters from other genes, in an attempt to allow an earlier start of butanol production during the growth phase than is the case with the wild-type cells. The aldehyde dehydrogenase from C. beijerinckii NRRL B593 (ald) and alcohol dehydrogenase from C. beijerinckii NRRL B592 (adhA) were placed under the control of the promoter from the acid-producing operon (the BCS operon) in one vector, and under the control of the promoter from the ferredoxin gene in another. In both cases, aldehyde dehydrogenase activity was produced earlier in the growth phase in transformed cells, but alcohol dehydrogenase activity was not. The adhA gene from C. beijerinckii NRRL B592 was paired with the adhB gene from the same organism in a third vector, both under the control of the promoter from the BCS operon. In cells transformed with this vector, alcohol dehydrogenase activity was observed earlier in the growth phase than it was in wild-type NRRL B592 cells. / Ph. D.

Professional associations must have a significant level of membership to be effective. Georgia membership is increasingly low; therefore, ADHA cannot represent dental hygienists’ interests. This study determined factors that caused dental hygienists to continue to forgo membership in the ADHA. Several theoretical views of professional membership were considered. The sample was acquired from an unbiased systematic sampling of 50% (3,270) of registered dental hygienists and a convenience sampling of ADHA nonmembers at 2 continuing education seminars in Georgia. Data collection procedures included an electronic cover letter, consent form, and survey via Survey Monkey or hard copies for seminars. Three hundred sixteen participated yielded a 9.6% return rate. Participants were primarily women, holding associate degrees, and graduates of programs in Georgia. Participants worked full time in private practice, were satisfied with their working hours, and did not join GDHA because membership fee is too high or not sure of benefits offered. Twenty-one percent stated that lowering membership fee would entice them to join, and participants indicated they obtained their continuing education hours at the Hinman (52%) convention and online (27%).

[pt] O estudo tem como foco a negociação de identidades em situação de conflito em contexto de consulta médica pediátrica de crianças e adolescentes com diagnóstico de Transtorno de Déficit de Atenção e Hiperatividade (TDAH), em atendimento de rotina conduzido pela médica. O objetivo consiste em criar inteligibilidades sobre os conflitos familiares consequentes do transtorno e as identidades projetadas/negociadas por pais, crianças e adolescentes com TDAH, para si e para o outro. A pesquisa está ancorada em linhas teóricas da fala-em-interação em atendimento clínico. Situa-se na Linguística Aplicada das Profissões, em articulação com a Análise da Conversa Etnometodológica, em contexto institucional, com a Sociolinguística Interacional e com os estudos discursivos sobre identidades. A metodologia da pesquisa, de natureza qualitativa e interpretativista, com gravação em vídeo de quatro consultas pediátricas, tem caráter etnográfico, mediante observação participante na antessala de atendimento. Os dados foram transcritos de acordo com convenções da Análise da Conversa Etnometodológica. Os resultados das análises mostram a prática profissional da médica nos enquadres de consulta clínica e de orientação psicoeducativa. A médica realiza tanto atividades relacionadas a tarefas de avaliação física e comportamental das crianças e dos adolescentes, em ações que visam ao tratamento medicamentoso e psicológico do TDAH, quanto atos comunicativos como formuladora, mediadora e conselheira na intermediação de conflitos emergentes da inter-relação TDAH, família e escola, resultantes do comportamento dos filhos nas relações familiares e do baixo rendimento acadêmico destes no contexto escolar. Os pais se alinham junto à médica, no enquadre de transtornos escolares dos filhos, e estabelecem enquadres conflitantes junto aos filhos; projetam para si identidades cujos atributos oscilam entre participativos, compreensivos e responsáveis, e impacientes, frustrados e esgotados. As identidades que projetam para os filhos apresentam-se, por vezes, contraditórias, entre filhos amorosos, perspicazes e irritantes; e alunos inteligentes, ineptos e displicentes. As crianças e os adolescentes, embora se alinhem com a médica, nos enquadres de consulta e orientação, rejeitam o estigma de TDAH e projetam para si identidades de alunos e filhos respeitosos e intelectualmente capazes; e para seus pais, na maioria das vezes, de pais impacientes e exigentes em sua educação. O estudo proporciona maior entendimento da complexidade e das múltiplas atividades da atuação profissional da médica na consulta pediátrica, e contribui para uma melhor compreensão das experiências cotidianas de pais, crianças e adolescentes com TDAH, marcadas por conflitos desestruturantes da harmonia entre esses atores sociais nos contextos da escola e da família. / [en] The study focuses on the negotiation of identities during conflict situations in the context of pediatric appointments for children and teenagers diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), in routine care conducted by the doctor. The main purpose consists on creating intelligibilities about the family conflicts resultant from the disorder and the identities projected/negotiated by the parents, children and teenagers with ADHA, for themselves and others. The research is based on theoretical lines of speech-in-interaction regarding clinical care. It is situated on Professions Applied Linguistics, in articulation with the Ethnomethodological Conversation Analysis, in an institutional context, in Interational Sociolinguistics and on discursive studies about identities. The research methodology, of a qualitative and interpretive nature, with video recording of four pediatric appointments, has an ethnographic character, by a participant observation in the Doctor’s office waiting room. Data were transcribed in accordance with conventions of the Ethnomethodological Conversation Analysis. The analyzes results indicate the professional practice of the Doctor concerning clinical care and the psycho-educative orientation. The Doctor carries out activities related to physical evaluation and behavior tasks of children and teenagers, in actions that aim at the ADHA medicated and psychological treatment, and also the communicative acts as a formulator, mediator and advisor when intermediating conflicts emerging from the ADHA, family and school inter-relation, resultant from the behavior of the children in family relation and the their low academic performance in the school context. The parents align with the Doctor, in the framings of their children school disorders, and stablish conflicting framings together with their children; they project to themselves the identities whose attributes oscillate between participative, comprehensive and responsible, and impatient, frustrated and exhausted. The identities that project toward children are occasionally presented as contradictory, among the children considered lovely, insightful and annoying; and intelligent, inept and ungracious students. Children and teenagers, although being aligned with the Doctor, in the framings of appointments and orientation reject the ADHA stigma and project to themselves the identities of students and children considered to be respectful and intellectually capable; and for their parents, most of the time, identities of impatient and demanding parents regarding education. The study provides a greater understanding of the complexity and the multiple activities of the professional performance of the Doctor during the pediatric care, and contributes for a better understanding of the daily experiences of parents, children and teenagers with ADHA, marked by destabilizing conflicts of harmony between these social authors in the school and family contexts.
