Super-ego: ego tenant

The process of metapsychologic concepts development in Freud`s works is not linear; on the contrary, it oscillates, with comings and goings, temporary abandonments, ambiguities, contradictions. Within key metapsychology concepts, the concept of superego is certainly complex and troublesome, for not only it holds many definitions but its scope is also wide. From clinic to metapsychology, going across the theory of culture, the superego plays a role in all aspects of psychoanalytic investigation, misunderstandings appearing quite frequently, therefore, among those who comment it. In addition to it, Freud himself was no faithful historian of his own concepts. The present paper proposes to undo a few ambiguities in what concerns the evolution process of ego conception, beginning from a fundamental metapsychologic problem, which is the remake of the notion of ego. We support that changes in the ego theory were crucial to the elaboration of conceptual basis of super-ego in its legislative function. We will see that the super-ego begins its story as a discreet tenant to the ego to become tyrannical and usurper, threatening the ego integrity.

Determination of Tetracycline in Environmental Water Samples at a Graphite-Polyurethane Composite Electrode

A bare graphite-polyurethane composite was evaluated in the tetracycline (TC) determination in natural water samples. Using differential pulse voltammetry (DPV), a linear response was observed in the range of 4.00-40.0 mu mol L-1 with limit of detection of 2.80 mu mol L-1, without the need of surface renewing between successive runs. During the tetracycline determination in water samples, recoveries between 92.6 and 100% were found. The results for TC determination in water samples after a pre-concentration stage agreed with spiked value at a 95% confidence level according to student t-test.

Marco legal do Programa Nacional de Alimentação Escolar: uma releitura para alinhar propósitos e práticas na aquisição de alimentos

This essay aims to discuss the acquisition of food by the National School Feeding Program in light of its current legal framework with a view to promote healthy and culturally sound eating habits that help to improve the health of Brazilian school children and promote local development. The study presents an analysis of the current legislation of the National School Feeding Program, evidencing its intention to influence the Brazilian feeding system and the food pattern of its population using school meals, highlighting the gaps that challenge the achievement of major changes in the execution of the program. From this analysis and based on the high and growing consumption of ultra-processed foods in Brazil, and considering the disadvantages of these foods when compared with minimally-processed or fresh foods, a proposal is developed to guide the construction of a list of foods that is consistent with the current legal framework of the Program and its objectives. It is argued that the prevalence of minimally-processed or fresh foods in school meals can be a strategy to rescue the healthy-food heritage and strengthen local development if promoting family farming.

Ingestão habitual de vitamina K em adultos e idosos

OBJETIVO: O principal objetivo deste trabalho é avaliar a ingestão habitual de vitamina K em adultos e idosos. MÉTODOS: Foi realizado um estudo transversal com a participação de 173 indivíduos de ambos os sexos. A ingestão habitual de cada participante foi avaliada pela aplicação de três recordatórios 24h não consecutivos. As variabilidades intra e interpessoal foram avaliadas por meio do software PC-SIDE. RESULTADOS: A média de ingestão de vitamina K na amostra foi de 110,7µg/dia, com uma mediana de 99µg/dia; os idosos foram os que apresentaram maiores valores de ingestão, com uma mediana de 104µg/dia. O consumo de vitamina K entre adultos e idosos foi estatisticamente diferente (p=0,00), e o consumo de hortaliças apresentou forte correlação com o consumo de vitamina K total. CONCLUSÃO: Independentemente da faixa etária e do sexo, a ingestão de vitamina K foi insuficiente em quase metade da amostra, o que pode ocasionar um maior risco de inadequação dietética e acarretar problemas ósseos no futuro e/ou agravar os já presentes quando se trata da população idosa.

Xylella fastidiosa: An in vivo system to study possible survival strategies within citrus xylem vessels based on global gene expression analysis

Xylella fastidiosa inhabits the plant xylem, a nutrient-poor environment, so that mechanisms to sense and respond to adverse environmental conditions are extremely important for bacterial survival in the plant host. Although the complete genome sequences of different Xylella strains have been determined, little is known about stress responses and gene regulation in these organisms. In this work, a DNA microarray was constructed containing 2,600 ORFs identified in the genome sequencing project of Xylella fastidiosa 9a5c strain, and used to check global gene expression differences in the bacteria when it is infecting a symptomatic and a tolerant citrus tree. Different patterns of expression were found in each variety, suggesting that bacteria are responding differentially according to each plant xylem environment. The global gene expression profile was determined and several genes related to bacterial survival in stressed conditions were found to be differentially expressed between varieties, suggesting the involvement of different strategies for adaptation to the environment. The expression pattern of some genes related to the heat shock response, toxin and detoxification processes, adaptation to atypical conditions, repair systems as well as some regulatory genes are discussed in this paper. DNA microarray proved to be a powerful technique for global transcriptome analyses. This is one of the first studies of Xylella fastidiosa gene expression in vivo which helped to increase insight into stress responses and possible bacterial survival mechanisms in the nutrient-poor environment of xylem vessels.

The place of (explicit) grammar within the methods and approaches of foreign language teaching: in the north, in the centre or on the margins?

This article analyzes the role that has been attributed to grammar throughout the history of foreign language teaching, with special emphasis on methods and approaches of the twentieth century. In order to support our argument, we discuss the notion of grammar by proposing a conceptual continuum that includes the main meanings of the term which are relevant to our research. We address as well the issue of "pedagogical grammar" and consider the position of grammar in the different approaches of the "era of the methods" and the current "post-method condition" in the field of language teaching and learning. The findings presented at the end of the text consist of recognizing the central role that grammar has played throughout the history of the methods and approaches, where grammar has always been present by the definition of the contents' progression. The rationale that we propose for this is the recognition of the fact that the dissociation between what is said and how it is said can not be more than theoretical and, thus, artificial.

Processo maturacional, insatisfação corporal e comportamento alimentar inadequado em jovens atletas

Objetivo O objetivo deste estudo foi analisar a associação entre o processo maturacional, a insatisfação corporal e o comportamento alimentar inadequado, de acordo com o sexo, em jovens atletas. Métodos Participaram da pesquisa 580 indivíduos, de ambos os sexos, pertencentes a diferentes modalidades esportivas. Foram avaliados a maturação sexual, a maturação somática, a insatisfação corporal e o comportamento alimentar inadequado, por meio dos Critérios de Tanner, banco de Lohman, Body Shape Questionnaire e Eating Attitudes Test, respectivamente. O percentual de gordura foi estimado pela medição das dobras cutâneas, e a aferição de peso e de estatura foi utilizada para calcular o índice de massa corporal. Realizaram-se modelo Univariado de Covariância, regressão logística binária e regressão linear múltipla para análise dos dados. Resultados Os resultados demonstraram diferenças estatisticamente significativas (p<0,05) na insatisfação corporal entre os estágios maturacionais. Além disso, os meninos pré-púberes e púberes apresentaram maior probabilidade de insatisfação corporal em relação aos atletas pós-púberes (p<0,05), e o modelo de regressão logística mostrou associação entre os estágios maturacionais e o comportamento alimentar inadequado apenas no sexo masculino (p<0,05). Nas meninas, o processo maturacional explicou em 9% e 7% a variância da insatisfação corporal (p<0,05) e comportamento alimentar inadequado (p<0,05), respectivamente.

Dental health in Northern Chile's Atacama oases: Evaluating the Middle Horizon (AD 500-1000) impact on local diet

As one of the few areas apt for horticulture in Northern Chile's arid landscape, the prehistory of the Atacama oases is deeply enmeshed with that of the inter-regional networks that promoted societal development in the south central Andes. During the Middle Horizon (AD 5001000), local populations experienced a cultural apex associated with a substantial increase in inter-regional interaction, population density, and quantity and quality of mortuary assemblages. Here, we test if this cultural peak affected dietary practices equally among the distinct local groups of this period. We examine caries prevalence and the degree of occlusal wear in four series recovered from three cemeteries. Our results show a reduction in the prevalence of caries for males among an elite subsample from Solcor 3 and the later Coyo 3 cemeteries. Dental wear tends to increase over time with the Late Middle Horizon/Late Intermediate Period cemetery of Quitor 6 showing a higher average degree of wear. When considered in concert with archaeological information, we concluded that the Middle Horizon was marked by dietary variability wherein some populations were able to obtain better access to protein sources (e.g., camelid meat). Not all members of Atacameno society benefited from this, as we note that this dietary change only affected men. Our results suggest that the benefits brought to the San Pedro oases during the Middle Horizon were not equally distributed among local groups and that social status, relationship to the Tiwanaku polity, and interment in particular cemeteries affected dietary composition.

Consumo alimentar, estado nutricional e nível de atividade física em comunidade universitária brasileira

Objetivo Este estudo teve como objetivo avaliar a variabilidade e a frequência do consumo alimentar, o estado nutricional e o nível de atividade física em uma comunidade universitária brasileira. Métodos A amostra constitui-se de 303 voluntários (130 homens e 173 mulheres) pertencentes à comunidade universitária do interior de São Paulo e avaliada por meio da disponibilização pela Internet do Questionário de Frequência Alimentar do International Physical Activity Questionaire e por meio da coleta da descrição autorreferida do peso e da altura. Foi realizada análise descritiva dos dados, análise de frequência alimentar e teste do coeficiente de correlação de Spearman. Resultados Foram observados inadequação dos hábitos alimentares, sobrepeso e obesidade na amostra estudada. As correlações entre os grupos alimentares apresentaram valores de magnitude maiores no grupo de mulheres que se alimentam de forma mais adequada do que os homens, mas não foram observadas diferenças entre os sexos no nível de atividade física. Não houve correlação significativa entre grupos de alimentos consumidos, índice de massa corporal e nível de atividade física em ambos os sexos. Conclusão A comunidade universitária estudada apresentou baixo consumo de frutas, legumes e verduras, bem como consumo insuficiente de alimentos do grupo de cereais e leguminosas.
