Anorexia nervosa e bulimia nervosa: abordagem cognitivo-construtivista de psicoterapia

Abstract: Among the eating disorders, anorexia nervosa and bulimia nervosa are the ones that have made adolescent patients - often females and aged younger and younger - seek for help. This help is provided through a multidisciplinary treatment involving psychiatrists, psychologists and dietists. Psychotherapy has shown to be an efficient component for these patients' improvement. The present article aims at presenting a proposal of psychotherapeutic treatment based on a cognitive-constructivist approach.

Relativistic O ( q 4 ) two-pion exchange nucleon-nucleon potential: Configuration space

Abstract: We have recently performed a relativistic $O({q}^{4})$ chiral expansion of the two-pion exchange $NN$ potential, and here we explore its configuration space content. Interactions are determined by three families of diagrams, two of which involve just ${g}_{A}$ and ${f}_{\ensuremath{\pi}}$, whereas the third one depends on empirical coefficients fixed by subthreshold $\ensuremath{\pi}N$ data. In this sense, the calculation has no adjusted parameters and gives rise to predictions, which are tested against phenomenological potentials. The dynamical structure of the eight leading nonrelativistic components of the interaction is investigated and, in most cases, found to be clearly dominated by a well defined class of diagrams. In particular, the central isovector and spin-orbit, spin-spin, and tensor isoscalar terms are almost completely fixed by just ${g}_{A}$ and ${f}_{\ensuremath{\pi}}$. The convergence of the chiral series in powers of the ratio (pion mass∕nucleon mass) is studied as a function of the internucleon distance and, for $rg1\phantom{\rule{0.3em}{0ex}}\text{fm}$, found to be adequate for most components of the potential. An important exception is the dominant central isoscalar term, where the convergence is evident only for $rg2.5\phantom{\rule{0.3em}{0ex}}\text{fm}.$ Finally, we compare the spatial behavior of the functions that enter the relativistic and heavy baryon formulations of the interaction and find that, in the region of physical interest, they differ by about $5%$.

BSP/CGM algorithms for maximum subsequence and maximum subarray

Abstract: The maximum subsequence problem finds the contiguous subsequence of n real numbers with the highest sum. This problem appears in the analysis of DNA or protein sequences. It can be solved sequentially in O(n) time. In the 2-D version, given an n × n array A, the maximum subarray of A is the contiguous subarray that has the maximum sum. The sequential algorithm for the maximum subarray problem takes O(n 3) time. We present efficient BSP/CGM parallel algorithms that require a constant number of communication rounds for both problems. In the first algorithm, the sequence stored on each processor is reduced to only five numbers, so that the resulting values can be concentrated on a single processor which runs an adaptation of the sequential algorithm to obtain the result. The parallel algorithm requires O(n/p) computing time. In the second algorithm, the input array is partitioned equally among the processors and we first reduce each subarray to a sequence, and then apply the first algorithm to solve it. The parallel algorithm takes O(n 3/p) computing time. The good performance of the parallel algorithms is confirmed by experimental results run on a 64-node Beowulf parallel computer.

Educação Física no Ensino Fundamental: identificando o conhecimento de natureza conceitual, procedimentos e atitudinal

Abstract: The purpose of this study was to verify the knowledge characteristics to be learned in physical education classes in the four initial years of elementary education, identifying it in terms of its conceptual, procedural and attitudinal nature and discussing its pertinence in the scholastic environment. The pedagogical literature of the area was defined as the reference criterion to be investigated. Thirteen papers were selected and their content was analyzed. The scholastic knowledge, related to teaching physical education, is composed by facts, concepts, principles, procedures, norms, values and attitudes. However, these elements of knowledge were presented in a fragmented form and not always significant. A tendency was verified in prioritizing the knowledge related to procedural nature whereas the knowledge regarding the conceptualand attitudinal nature was superficially treated and seldom specific to physical education. Therefore, it is necessary to have an organized and systematized presentation of knowledge to be learned in physical education.

Estudo controlado da influência da atividade física em fatores de risco para doenças crônicas em indivíduos lesados medulares paraplégicos do sexo masculino

Abstract: O objetivo deste estudo foi comparar alguns parâmetros bioquimicos e de avaliacao nutricional, indicativo de risco de doencas cronicas em individuos lesados medulares com idade entre 18 e 45 anos. Foram avaliados 28 individuos divididos em dois grupos: praticantes de exercicio fisico (N=16) e sedentarios (N=12). Utilizou-se para analise a avaliacao do consumo alimentar, da composicao corporal e alguns parâmetros bioquimicos. Todos os parâmetros avaliados foram comparados atraves do teste t-student para variaveis independentes, assumindo como significativo o valor a < 0,05. O grupo sedentario apresentou uma tendencia a sobrepeso, a glicose plasmatica correlacionou-se com a adiposidade. No entanto, nao houve diferenca significativa entre a estimativa do gasto energetico basal e a ingestao calorica, o que sugere alteracao das necessidades energeticas. Ambos os grupos apresentaram valores diminuidos para a concentracao plasmatica de HDL-C e observou-se desbalanco na ingestao dos macronutrientes. Conclui-se que as formulas preditivas do gasto energetico basal superestimam os valores em lesados medulares, principalmente no grupo sedentario. A adequacao da dieta deve ser instituida independente de fatores de risco presentes. Futuros trabalhos poderiam estabelecer protocolos de avaliacao para este grupo populacional. Enquanto isso nao acontece, os metodos de avaliacao continuam incompletos e incertos.

As respostas de Berkeley ao ceticismo

Abstract: O artigo compara alguns aspectos da refutacao do ceticismo nos Principios e nos Tres dialogos. Embora normalmente nao se veja nenhuma diferenca importante entre essas obras, duas hipoteses sao defendidas aqui: de um lado, Berkeley desloca o foco de sua critica das ideias abstratas para a nocao de materia e, de outro, muda sua estrategia de combate, da enunciacao imediata da verdade para a lenta elaboracao das consequencias ceticas da nocao de materia. Berkeley’s answers to skepticism Abstract The topic of this paper is a comparison between Berkeley´s refutation of skepticism in the Principles and in the Three Dialogues. It is usually held that there is no philosophical difference between these two works. However, I suggest that not only Berkeley´s diagnosis of the causes of skepticism changes from his criticism of abstract ideas to the notion of matter, but also that he changes his strategy of refutation: from a direct statement of the truth of immaterialism to an examination of the consequences of the notion of matter.

Treinamento físico melhora a disfunção quimiorreflexa em ratos diabéticos por estreptozotocina

Abstract: O objetivo do presente estudo foi avaliar os efeitos do treinamento fisico na pressao arterial, na freq uencia cardiaca e na sensibilidade quimiorreflexa em ratos diabeticos por estreptozotocina. Os animais foram divididos em grupos controle (CS, n = 6), diabetico sedentario (DS, n = 6) e diabetico treinado (DT, n = 6). Uma semana apos a inducao do diabetes (Estreptozotocina, 50 mg/kg), ratos machos Wistar foram submetidos a um protocolo de treinamento fisico em esteira ergometrica por 10 semanas. Os sinais de pressao arterial foram gravados e processados em um sistema de aquisicao de dados (CODAS,1KHz). Cianeto de potassio (KCN,100 ug/kg) foi utilizado para avaliar a resposta bradicardica desencadeada pela estimulacao dos quimiorreceptores. A bradicardia e a hipotensao do diabetes (DS:274 ± 6 bpm e 94 ± 2 mmHg vs CS:332 ± 5 bpm e 108 ± 2 mmHg) foram atenuadas pelo treinamento fisico (DT:299 ± 5 bpm e 107 ± 2 mmHg). A resposta bradicardica foi menor nos ratos DS (33 ± 5 bpm) quando comparado aos ratos CS (182 ± 3 bpm) e DT (89 ± 10 bpm). Concluindo, o treinamento fisico reverteu a hipotensao e a bradicardia e melhorou a sensibilidade quimioreflexa em ratos STZ. Considerando que diabeticos com reflexos cardiovasculares anormais apresentam maior mortalidade que diabeticos com funcao reflexa autonomica normal, os resultados obtidos sugerem que o treinamento fisico pode contribuir para a reducao do risco cardiovascular nesta populacao devendo ser considerado no manejo do paciente diabetico

The truth according to James

Abstract: Pragmatist truth – as advocated e.g. by Peirce and James – is usually taken to integrate four key elements: (1) the value of truth is likened to some kind of utility; (2) truth is naturally taken to consist in correspondence; (3) truth is essentially linked to the possibility of knowledge; (4) truth is not relative but absolute. Critics have never tired to question the individual and collective consistency of these four constraints. The principal challenge issued to pragmatists (and many other essentially epistemic theories of truth) always consisted in developing viable interpretations of the key notions utility, correspondence, knowability and absoluteness that would render the pragmatist proposal at least consistent. I shall take up that challenge developing some ideas of James in a contemporary garb.
