Full textAbstract:
The factor structure of the Luria Nebraska Neuropsychological Battery (LNNB) Form II was examined. A principle components factor analysis was performed on a sample of 102 psychiatric and neurologic subjects. It was necessary to remove 45 items from the analysis due to perfect performance by most subjects. The results were orthogonally rotated to simple structure using a Varimax method of rotation, and then compared to previous LNNB Form I and Form II results. Thirty-three factors were generated in the Exploratory Factor Analysis (EFA) . There was a very high agreement with the factors from Form I. Only one new factor was identified that didn't have a comparable Form I factor, and this factor appears to have neurological support. The similarity of the factor solutions between the two forms supports the continued use of factors derived from Form I for the interpretation of Form II, and supports the underlying structure presupposed by Lurian constructs. The present study also tested the significance of the hypothesized factor structures through confirmatory factor analysis (CFA). No hypothesis about the underlying factor structure based on previous exploratory studies was supported. The CFA did suggest that the best factor solution to the LNNB Form II is one that (a) has correlated factors and (b) has items loading on more than one factor. The confirmatory results were interpreted as not supporting the current exploratory results, or the previous factor analytic results. Problems notwithstanding, researchers may be better directed to propose factor models for the LNNB that have correlated factors, and to work samples approaching the 10 to 1 recommended sample size for multivariate analysis. One conclusion that was drawn from the concurrence between the two Form II studies pertains to psychiatric populations used in both studies. It was necessary to exclude a large number of items in each study due to perfect performance by most of the subjects on those items. Most of the items removed were identical in both studies supporting the notion that a shortened version of the LNNB could be administered to psychiatric populations.

Full textAbstract:
Utilizada amplamente como agente terapêutico no tratamento da leucemia linfoblástica aguda (LLA), a L-Asparaginase II (ASNase) é uma enzima que atua diminuindo a concentração de asparagina livre no plasma. Dessa forma, impede o fornecimento de asparagina para a proliferação de células malignas, as quais ao contrário das células saudáveis, não conseguem sintetizar a asparagina. A ASNase utilizada atualmente no Brasil é importada, o que gera problemas com custo e abastecimento. Sendo assim, é notavelmente atrativa a procura por sistemas que apresentem níveis elevados de expressão de asparaginase e o encontro de formas de produzir tal enzima para um fácil acesso e, se possível, com menor potencial alérgico. Isso nos incentiva a estudar a produção biotecnológica de ASNase produzida em Escherichia coli BL21 (DE3) recombinante que super expressa esta enzima. O objetivo deste trabalho foi estabelecer, em agitador orbital e sistema descontínuo, os parâmetros do cultivo e indução da bactéria Escherichia coli BL21 visando à produção de ASNase, os quais serão úteis para futuros estudos em sistema descontínuo-alimentado. Nosso trabalho avaliou fatores que influenciam a fase de crescimento e/ou a fase de indução da E. coli BL21 (DE3): meio de cultivo baseado na composição elementar, controle do pH, uso de glicose ou glicerol como fonte de carbono, formação de acetato, tempo inicial e final da indução, permeabilização celular para secreção da ASNase, concentração de indutor, temperatura de pós-indução. Nós apresentamos uma estratégia para produção extracelular de ASNase em E. coli BL21 (DE3) pelo crescimento em meio Luria Bertani (LB) modificado para permeabilização celular. A produtividade volumétrica de ASNase extracelular foi 484 IU L h-1 em agitador orbital, correspondendo a 89 % de secreção após 24h de pós-indução com IPTG a 37 ºC. Isto representou rendimento 50 % maior para a ASNase total e 15,5 vezes mais secreção de ASNase em relação ao uso do meio LB modificado. Entretanto no cultivo em biorreator de 3 L nas mesmas condições (exceto a forma de aeração: 500 rpm de agitação e 1 vvm de vazão de ar, kLa = 88 h-1) operado em regime descontínuo foram obtidos resultados semelhantes aos cultivos em agitador orbital, sendo a produtividade volumétrica da ASNase extracelular igual a 525 IU L h-1 após 20 h de pós-indução. A biomassa obtida para agitador orbital e biorreator foi 3,26 e 2,63 g L-1, respetivamente. Por esse motivo, esses resultados foram considerados promissores para aumentar a produtividade nos futuros ensaios em biorreator operado em regime descontinuo-alimentado.Widely used as a therapeutic agent in the treatment of acute lymphoblastic leukemia (ALL), L-Asparaginase II (ASNase) is an enzyme that works by reducing the concentration of free asparagine in plasma. Thus, it prevents the delivery of asparagine to the proliferation of malignant cells, which unlike healthy cell, cannot synthesize asparagine. ASNase currently used in Brazil is imported, which causes problems with cost and supply. Thus, the search for systems with high levels of asparaginase expression and the finding of ways to produce this enzyme for easy access and, if possible, with a lower allergic potential, are strikingly attractive. This encourages us to study the biotechnological production of ASNase in recombinant Escherichia coli BL21 (DE3) which super expresses this enzyme. The objective of this work was to establish, in shaker and batch bioreactor system, growth and induction parameters of the Escherichia coli BL21 aiming the production of ASNase, which will be useful for future studies in a fed-batch system. Our work evaluated factors that influenced the growth and induction phase of E. coli BL21 (DE3): culture medium based on elemental composition, pH control, use of glucose or glycerol as carbon source, formation of acetate, initial and final induction time, cellular permeabilization for ASNase secretion, inducer concentration, post-induction temperature. We performed a strategy for extracellular production of ASNase in E. coli BL21 (DE3) by growing in modified Luria Bertani (LB) medium for cell permeabilization. The volumetric productivity of extracellular ASNase was 484 IU L h-1 on shaker, which reached 89% secretion at 24 h of post-induction with IPTG at 37°C. This represented an increase yield of 50 % regarding to the total ASNase formed and 15.5 times the ASNase secretion as compared to that attained with LB modified. While in batch 2L-bioreactor cultivation under the same conditions (except for the aeration employed: 500 rpm of stirring and 1 vvm of air flow, kLa = 88 h-1) it was obtained similar results in relation to shaker cultures. The volumetric productivity of extracellular ASNase was 525 IU L h-1 at 20 h of post-induction. The biomass obtained for shaker and bioreactor were 3.26 and 2.63 g L-1, respectively. For this reason, we consider these promising results to increase productivity in future studies in bioreactor operated as fed-batch regimen.

Full textAbstract:
The Luria-Nebraska Neuropsychological Battery (LNNB) was published in 1980 as an attempt to provide clinicians with a standardized version of the neuropsychological assessment and diagnostic procedures proposed by A. R. Luria and A, L. Christensen. Research on the LNNB included a series of factor analyses for each of eleven clinical scales. The analyses were completed on the combined scores obtained from a sample of normal, brain-damaged, and psychiatric populations.
A second version of the LNNB was published in 1985 as a largely parallel version of Form I, but included changes in stimulus materials, administration procedures, and scoring procedures. The present study completed factor analyses on same eleven clinical scales using data generated with the newer LNNB Form II. The statistical procedures and criteria employed in the present investigation were identical to those used earlier on Form I to allow for comparisons between the two resulting sets of factor structures. The patient populations were different, however, in that all subjects in the current study were receiving inpatient care in a private psychiatric hospital which specializes in long-term treatment.
Despite the changes in materials and procedures and the difference in subject parameters, the factors identified in the present investigation are similar to those seen in the Form I studies. However, two trends were observed when comparing the two sets of factor structures. First, in the present study several items were excluded from the statistical procedures because they were performed perfectly by almost everyone and the resulting scores lacked statistical variance. Second, more homogenous factors were obtained with the Form II analysis. That is, some of the complex LNNB Form I factors were reduced to two or more simpler factors. The results of the study lend support to Luna's conceptual model of higher cortical function and to the reliability of the LNNB as an assessment instrument.

B rucella lipopolysaccharide is an important component of virulence in
brucellosis. Recent research in macrophage models has shown that Brucella
LPS does not behave like classical LPS by stimulating potent inflammatory
responses. The central hypothesis of this work is that O-antigen is dynamic
signaling molecular and participates in complex interactions with the host to
promote productive infection. A corollary to this is that the host environment is
dynamic, and Brucella has evolved mechanisms to cope with changing
environments. In an effort to understand the contribution of Brucella LPS to
virulence and pathogenesis, the function of a metabolic locus important in the
synthesis of LPS has been demonstrated and complemented. The spontaneous
loss of LPS expression has been characterized. Contribution of LPS to
acquisition of the host environment in tissue culture and mouse models has
been explored. This work demonstrated that genes outside the O-antigen
biosynthesis ( manBA) cluster contribute to LPS biosynthesis. Further high frequency mutation involving manBA is partly responsible for observed
dissociation of Brucella strains. Finally, work herein attempts to look at the role
of LPS in acquisition of the host environment and shows that LPS is important
for recruiting particular cell populations within a host model of brucellosis.

A presente pesquisa, de natureza conceitual, procurou compreender a obra de A. R. Luria (1902-1977) como determinada pela concretude de seu contexto histórico, isto é, a Rússia pós-revolucionária como marco inicial de seus estudos e pesquisas e, posteriormente, a União Soviética sob o regime stalinista. Para isso, foi realizada uma extensiva pesquisa das publicações deste autor, evidenciando a crescente sistematização dos conceitos e método para a compreensão da constituição da consciência humana, tomando-se por base seus fundamentos filosóficos e epistemológicos. Os estudos de Luria foram organizados por etapas - antes de Vigotski, em conjunto com ele e após sua morte - devido ao aparente redirecionamento dado às suas pesquisas, durante o stalinismo, que o fez concentrar-se mais na área da neuropsicologia. Observou-se que suas obras mais conhecidas no Ocidente quando desligadas de seus fundamentos marxistas, vêm dando base a apropriações indevidas de seus conceitos e associações a autores cuja base epistemológica é contrária. Entende-se que apenas o resgate da obra luriana em seu conjunto, bem como de seus fundamentos marxistas possibilita compreender o funcionamento cerebral como materialização das funções psicológicas superiores, de origem cultural, opondo-se ao reducionismo biológico ou subjetivo, hegemônico na atualidade. Para esta empreita, foi demonstrado que Luria deu continuidade aos pressupostos vigotskianos em suas pesquisas sobre o funcionamento cerebral e suas patologias, a despeito do acirramento do stalinismo na União Soviética após a morte de Vigotski, em 1934, superando a compreensão do homem como mais uma espécie sujeita, em seu desenvolvimento, às condições de maturação de seu organismo biológico, e, portanto, limitada por tais condições que independem de aspectos sócio-culturais, em direção a uma...
The present research, of conceptual nature, aimed at understanding the work of A. R. Luria (1902 - 1977) as determined by the concreteness of its historical context, i.e., the postrevolutionary Russia as the initial mark for his studies and research and, subsequently, the Soviet Union under Stalinist regime. In order to do so, extensive research was done into this author s publications, evidencing the increasing systematization of concepts and method for the understanding of how the human conscience is constituted, having its philosophical and epistemological foundations as basis. Luria s studies were organized in stages - before Vigotski, along with him and after his death - due to the apparent redirection given to his research, during Stalinism, which made him focus more on the neuropsychological area. It was observed that his most renowned pieces in the West when disconnected of its Marxist foundations have been giving basis to improper appropriations of its concepts and associations to authors whose epistemological basis is contrary. It is understood that only the rescue of Luria s work in its whole, as well as its Marxist foundations, enables the understanding of the brain work as materialization of the superior psychological functions, of cultural origin, opposing to the biological or subjective reductionism, presently hegemonic. For this purpose, it was demonstrated that Luria continued with the Vigotskian postulations in his research on the brain work and its pathologies, despite the incitement of Stalinism in the Soviet Union after Vigotski's death in 1934, overcoming the comprehension of the human being as one more species subject, in its development, to the conditions of maturation in its biological organism, and, therefore, limited by such conditions which prevent the social-cultural aspects, towards a new way of understanding human...

Full textAbstract:
There is a growing appreciation for the insight mathematical models can yield on biological systems. In particular, due to the challenges inherent in experimental observation of disease progression, models describing the genesis, growth and evolution of cancer have been developed. Many of these models possess the common feature that one particular type of cellular population initiates a further, distinct population. This thesis explores two models containing this feature, which also employ branching processes to describe population growth. Firstly, we consider a deterministically growing wild type population which seeds stochastically developing mutant clones. This generalises the classic Luria- Delbruck model of bacterial evolution. We focus on how differing wild type growth manifests itself in the distribution of clone sizes. In our main result we prove that for a large class of wild type growth, the long-time limit of the clone size distribution has a general two-parameter form, whose tail decays as a power-law. In the second model, we consider a fully stochastic system of cells in a growing population that can undergo birth, death and transitions. New cellular types appear via transitions, examples of which are genetic mutations or migrations bringing cells into a new environment. We concentrate on the scenario where the original cell type has the largest net growth rate, which is relevant for modelling drug resistance, due to fitness costs of resistance, or cells migrating into contact with a toxin. Two questions are considered in our main results. First, how long do we wait until a cell with a specific target type, an arbitrary number of transitions from the original population, exists. Second, which particular sequence of transitions initiated the target population. In the limit of small final transition rates, simple, explicit formulas are given to answer these questions.

This dissertation, which has a bibliographical nature, was centered upon the analysis of the categories of labor and language in the work of Alexander Romanovich Luria. From the point of view of Marxian-Lukacsian ontology, it assumed labor as the act that founded human world and all the complexes which encompass human experience. Therefore, it elected as the main hypothesis, that labor, as the founding category of the social being, with the special participation of language, accounts for the origin of the conscientious activity and of the higher psychological functions in humans, both resulting from the necessities engendered by human activity itself. In this perspective, we tried to investigate to what extent the treatment ascribed by Luria to the categories of labor and language are consistent with the premises put by the ontology of social being, identifying, moreover, their relationship within the genesis and development of the higher psychological functions. Before discussing the main research questions, we considered of great importance to present Luriaâs biography, in order to place the historical context in which his ideas were fostered, attesting his affiliation with Vigotski and Leontiev, as well, in the field of historical-dialectical materialism. The results of the research indicated that the treatment given by Luria to the categories of labor and language agree with the fundamental ontological concepts, emphasizing labor as the primary category in relation to the other complexes, herein included the complex of language. In this context, labor, together with language, brought about human conscientious activity, developing in man, complex functions, which are not present in animals.

Le dernier pan de la these enumere les principaux themes ethiques de la pensee de l'auteur dont l'ideal de justice et charite constitue le fil conducteur. On peut remarquer que l'exegese de l'auteur le situe dans le courant de la pensee hassidique avec une coloration orientale qui le place parmi les grands maitres de la cabale et du hassidisme sepharadeThe aim of the thesis is to reveal the originality of rabbi yaacov abihserah. The first part retraces the main currents of the kabbalah and defines the sphere of influence within which he was active, following the tradition of rabbin isaac louria. The second part examines the specificity of the commentator's hermenentical method and his use of kabbalistic techniques such as "guematria" ans "notarigon" the third part presents the major ideas of the kabbalah treated by rabbi yaacov abihserah with the emphasis falling on the eschaatalogical process of the restoration of the divine presence. The las part of the thesis enumerates the leading ethical themes of the expositor's thought, which is permeated throughout with an ideal of justice and charity. Rabbi yaacov abihserah's exegetical work places him in the mainstream of chassidic thought, albeit with oriental overtones, and thus ranks him among the great masters of the kabbalah and sephardic chassidism

Full textAbstract:
Les modèles de mutations décrivent le processus d’apparitions rares et aléatoires de mutations au cours de lacroissance d’une population de cellules. Les échantillons obtenus sont constitués de nombres finaux de cellules mutantes,qui peuvent être couplés avec des nombres totaux de cellules ou un nombre moyen de cellules en fin d’expérience.La loi du nombre final de mutantes est une loi à queue lourde : de grands décomptes, appelés “jackpots”,apparaissent fréquemment dans les données.Une construction générale des modèles se décompose en troisniveaux. Le premier niveau est l’apparition de mutations aléatoires au cours d’un processus de croissance de population.En pratique, les divisions cellulaires sont très nombreuses, et la probabilité qu’une de ces divisions conduise à une mutation est faible,ce qui justifie une approximation poissonnienne pour le nombre de mutations survenant pendant un temps d’observation donné.Le second niveau est celui des durées de développement des clones issus de cellules mutantes. Du fait de la croissance exponentielle,la majeure partie des mutations ont lieu à la fin du processus, et les durées de développement sont alors indépendanteset exponentiellement distribuées. Le troisième niveau concerne le nombre decellules qu’un clone issu d’une cellule mutante atteint pendant une durée de développement donnée.La loi de ce nombre dépend principalement de la loi des instants de division des mutantes.Le modèle classique, dit de Luria-Delbrück, suppose que les développements cellulaires des cellules normales aussi bien que mutantess’effectue selon un processus de Yule. On peut dans ce cas calculer expliciter la loi du nombre final de mutantes.Elle dépend de deux paramètres, qui sont le nombre moyen de mutations et le paramètre de fitness (ratio des taux de croissance des deux types de cellules).Le problème statistique consiste à estimer ces deux paramètres au vu d’un échantillon denombres finaux de mutantes. Il peut être résolu par maximisation de la vraisemblance,ou bien par une méthode basée sur la fonction génératrice. Diviser l'estimation du nombre moyen de mutations par le nombre total de cellulespermet alors d'estimer la probabilité d’apparition d’une mutation au cours d’une division cellulaire.L’estimation de cette probabilité est d’une importancecruciale dans plusieurs domaines de la médecine et debiologie: rechute de cancer, résistance aux antibiotiques de Mycobacterium Tuberculosis, etc.La difficulté provient de ce que les hypothèses de modélisation sous lesquelles la distribution du nombre final de mutants est explicitesont irréalistes.Or estimer les paramètres d’un modèle quand la réalité en suit un autre conduit nécessairement à un biais d’estimation.Il est donc nécessaire de disposer de méthodes d’estimation robustes pour lesquelles le biais, en particulier sur la probabilité de mutation,reste le moins sensible possible aux hypothèses de modélisation.Cette thèse contient une étude probabiliste et statistique de modèles de mutations prenant en compte les sources de biais suivantes : durées de vie non exponentielles, morts cellulaires,variabilité du nombre final de cellules, durées de vie non-exponentielles et non-identiquement distribuées, dilution de la population initiale.Des études par simulation des méthodes considérées sont effectuées afin de proposer, selon les caractéristiques du modèle,l’estimation la plus fiable possible. Ces méthodes ont également été appliquées à desjeux de données réelles, afin de comparer les résultats avec les estimations obtenues avec les modèles classiques.Un package R a été implémenté en collaboration avec Rémy Drouilhet et Stéphane Despréaux et est disponible sur le CRAN.Ce package est constitué des différents résultats obtenus au cours de ce travail. Il contient des fonctions dédiées aux modèles de mutations,ainsi qu'à l'estimation des paramètres. Les applications ont été développées pour le Labex TOUCAN (Toulouse Cancer)Mutation models are probabilistic descriptions of the growth of a population of cells, where mutationsoccur randomly during the process. Data are samples of integers, interpreted as final numbers ofmutant cells. These numbers may be coupled with final numbers of cells (mutant and non mutant) or a mean final number of cells.The frequent appearance in the data of very large mutant counts, usually called “jackpots”, evidencesheavy-tailed probability distributions.Any mutation model can be interpreted as the result of three ingredients. The first ingredient is about the number of mutations occuring with small probabilityamong a large number of cell divisions. Due to the law of small numbers, the number of mutations approximately follows aPoisson distribution. The second ingredient models the developing duration of the clone stemming from each mutation. Due to exponentialgrowth, most mutations occur close to the end of the experiment. Thus the developing time of arandom clone has exponential distribution. The last ingredients represents the number of mutant cells that any clone developing for a given time will produce. Thedistribution of this number depends mainly on the distribution of division times of mutants.One of the most used mutation model is the Luria-Delbrück model.In these model, division times of mutant cells were supposed to be exponentially distributed.Thus a clone develops according to a Yule process and its size at any given time follows a geometric distribution.This approach leads to a family of probability distributions which depend on the expected number of mutations and the relative fitness, which is the ratio between the growth rate of normal cells to that of mutants.The statistic purpose of these models is the estimation of these parameters. The probability for amutant cell to appear upon any given cell division is estimated dividing the mean number of mutations by the mean final number of cells.Given samples of final mutant counts, it is possible to build estimators maximizing the likelihood, or usingprobability generating function.Computing robust estimates is of crucial importance in medical applications, like cancer tumor relapse or multidrug resistance of Mycobacterium Tuberculosis for instance.The problem with classical mutation models, is that they are based on quite unrealistic assumptions: constant final number of cells,no cell deaths, exponential distribution of lifetimes, or time homogeneity. Using a model for estimation, when thedata have been generated by another one, necessarily induces a bias on estimates.Several sources of bias has been partially dealed until now: non-exponential lifetimes, cell deaths, fluctuations of the final count of cells,dependence of the lifetimes, plating efficiency. The time homogeneity remains untreated.This thesis contains probabilistic and statistic study of mutation models taking into account the following bias sources:non-exponential and non-identical lifetimes, cell deaths, fluctuations of the final count of cells, plating efficiency.Simulation studies has been performed in order to propose robust estimation methods, whatever the modeling assumptions.The methods have also been applied to real data sets, to compare the results with the estimates obtained under classical models.An R package based on the different results obtained in this work has been implemented (joint work with Rémy Drouilhetand Stéphane Despréaux) and is available on the CRAN. It includes functions dedicated to the mutation models and parameter estimation.The applications have been developed for the Labex TOUCAN (Toulouse Cancer)

This study addresses the criticism leveled at A.C.T.
Mathematics teachers with regard to their failure to use
any other method of teaching than chalk-and-talk. By
considering the changed needs of society for mathematics
and the changed perceptions by society of education, the
criticism is placed in context.
The importance of spatial ability for mathematics is
examined in the context of theories of cognitive abilities
and its current under utilization within the classroom. On
the basis of the increased need to utilize more talent the
study was designed to operationalise in the classroom the
constructs of simultaneous and successive synthesis,
derived from Luria's model of brain functioning.
The question of gender differences in mathematics
achievment and spatial ability is addressed.
The possible role of the maturation of language in
determining differences in the acquistion of ability to
form simultaneous synthesis is briefly discussed.
The study was designed to utilize and enhance
simultaneous synthesis. By demonstrating an
Aptitude-Treatment Interaction it was intended to confirm
that students, who function at a high level in
simultaneous synthesis but at a low level in successive
synthesis, would achieve more with experience with spatial
activates than in a more traditional chalk-and-talk
classroom.
Gender differences in achievement were not found.
Gender differences in successive/simultaneous profiles
were found in accordance with theory predictions. The need
for the duration of longer treatment periods is briefly
discussed in the context of funding and the appearance of
greater efficiency of traditional teaching methods when
the students are functioning at the highest level of
symbolic thought.

Resumo: O objetivo central deste estudo refere-se a investigar os procedimentos matemáticos expressos oralmente pelos alunos na resolução de um problema de multiplicação, quando se busca o registro desses procedimentos pela escrita matemática aceita escolar e socialmente. Para abordar a questão investigativa: como acontece a passagem dos procedimentos de cálculo mental à escrita matemática, passando pela expressão oral, evidenciados na resolução de um problema referente a multiplicação na alfabetização de jovens e adultos? optamos por uma análise qualitativa dos dados produzidos.O trabalho de campo foi realizado com alunos de uma classe de alfabetização de jovens e adultos. O estudo apresenta a descrição dos encontros ocorridos no desenvolvimento das atividades do trabalho de campo, os diálogos em sala de aula e as produções dos alunos. O material alvo de análise consistiu dos registros do diário de campo da pesquisadora e dos registros produzidos pelos alunos, sendo analisado em três categorias: ¿ Procedimentos aditivos e procedimentos multiplicativos; ¿ A expressão oral de procedimentos e a produção de conhecimento matemático; ¿ A valorização do algoritmo escolar da multiplicação. Com as análises surgiram considerações que destacamos: a busca pela apropriação do algoritmo escolar da multiplicação por esses jovens e adultos como ato emancipador e conquista de autonomia; o papel da linguagem na apropriação desse conhecimento e o exercício da capacidade humana de ir além da experiência sensorial dando o salto rumo ao conhecimento racional
Abstract: The main objective of this study refers to investigate the mathematical procedure verbally expressed by the pupils in the resolution of a multiplication problem, when the register of theses procedures for the mathematical writing are accepted pertaining to school and socially. To approach the investigative question: how the pass of the procedures of mental calculate to mathematical writing happens, passing by the verbal expression, evidenced in a resolution of a problem referring to multiplication in the education of a young and adult people? We opt to nake a qualitative analysis of carried through with pupils of a young and adults education classroom. The study shows the description of the meetings accured during the activities of the work field, the dialogues in the classroom and the productions of the pupils. The material of analysis consisted of the registers of field of the researcher and the registers produced by the pupils, being analyzed in three categories: ¿ Aditives and multiplicatives procedures; ¿ The verbal expression of procedures and the production of mathematical knowledge; ¿ The valuation of school algorithm of multiplication.

Resumo: A presente pesquisa, de natureza conceitual, procurou compreender a obra de A. R. Luria (1902-1977) como determinada pela concretude de seu contexto histórico, isto é, a Rússia pós-revolucionária como marco inicial de seus estudos e pesquisas e, posteriormente, a União Soviética sob o regime stalinista. Para isso, foi realizada uma extensiva pesquisa das publicações deste autor, evidenciando a crescente sistematização dos conceitos e método para a compreensão da constituição da consciência humana, tomando-se por base seus fundamentos filosóficos e epistemológicos. Os estudos de Luria foram organizados por etapas - antes de Vigotski, em conjunto com ele e após sua morte - devido ao aparente redirecionamento dado às suas pesquisas, durante o stalinismo, que o fez concentrar-se mais na área da neuropsicologia. Observou-se que suas obras mais conhecidas no Ocidente quando desligadas de seus fundamentos marxistas, vêm dando base a apropriações indevidas de seus conceitos e associações a autores cuja base epistemológica é contrária. Entende-se que apenas o resgate da obra luriana em seu conjunto, bem como de seus fundamentos marxistas possibilita compreender o funcionamento cerebral como materialização das funções psicológicas superiores, de origem cultural, opondo-se ao reducionismo biológico ou subjetivo, hegemônico na atualidade. Para esta empreita, foi demonstrado que Luria deu continuidade aos pressupostos vigotskianos em suas pesquisas sobre o funcionamento cerebral e suas patologias, a despeito do acirramento do "stalinismo" na União Soviética após a morte de Vigotski, em 1934, superando a compreensão do homem como mais uma espécie sujeita, em seu desenvolvimento, às condições de maturação de seu organismo biológico, e, portanto, limitada por tais condições que independem de aspectos sócio-culturais, em direção a uma...

Abstract: The present research, of conceptual nature, aimed at understanding the work of A. R. Luria (1902 - 1977) as determined by the concreteness of its historical context, i.e., the postrevolutionary Russia as the initial mark for his studies and research and, subsequently, the Soviet Union under Stalinist regime. In order to do so, extensive research was done into this authors publications, evidencing the increasing systematization of concepts and method for the understanding of how the human conscience is constituted, having its philosophical and epistemological foundations as basis. Lurias studies were organized in stages - before Vigotski, along with him and after his death - due to the apparent redirection given to his research, during Stalinism, which made him focus more on the neuropsychological area. It was observed that his most renowned pieces in the West when disconnected of its Marxist foundations have been giving basis to improper appropriations of its concepts and associations to authors whose epistemological basis is contrary. It is understood that only the rescue of Lurias work in its whole, as well as its Marxist foundations, enables the understanding of the brain work as materialization of the superior psychological functions, of cultural origin, opposing to the biological or subjective reductionism, presently hegemonic. For this purpose, it was demonstrated that Luria continued with the Vigotskian postulations in his research on the brain work and its pathologies, despite the incitement of "Stalinism" in the Soviet Union after Vigotski's death in 1934, overcoming the comprehension of the human being as one more species subject, in its development, to the conditions of maturation in its biological organism, and, therefore, limited by such conditions which prevent the social-cultural aspects, towards a new way of understanding human...

McClanahan, Erin M. "The Contextualization of Tikkun Olam in American Reform Judaism." Digital Archive @ GSU, 2010. http://digitalarchive.gsu.edu/rs_theses/30.
Full textAbstract:
American Reform Judaism currently associates the Kabalistic term, tikkun olam, with one of its core principles, social justice. This association is relatively new, dating roughly to the 1950s. The appropriation of a Kabbalistic term by American Reform Judaism is unusual given the historical animosity of American Reform Judaism toward the Kabbalah. The purpose of this thesis to explain this appropriation by contextualizing the use of tikkun olam within American Reform Judaism. The method through which this will be accomplished is the analysis of official documents, journal articles and theological discussions found within the American Reform movement. The thesis concludes that American Reform Judaism chose to appropriate tikkun olam and associate it with social justice in order to locate social justice in a historically Jewish context. This reworking of the concept of social justice to place it within a specifically Jewish frame work reflects the theological shift which occurs in reaction to the Holocaust, fears over Jewish assimilation and other social factors taking place during the 1940s and 1950s.

O objetivo deste projeto de pesquisa foi contribuir para a melhor compreensao do impacto das malformacoes do CC sobre o desenvolvimento das funcoes cognitivas e comportamentais, por meio de um estudo clinico descritivo. Participaram deste estudo, 16 individuos, de ambos os sexos e entre 6 e 18 anos de idade, diagnosticados com malformacoes do CC, encaminhados para o ambulatorio de neuroplasticidade do NANI/CPN. Foram realizadas avaliacao das funcoes cognitivas e comportamentais e o desempenho nos testes foi comparado a normas por idade. Considerando tipo de malformacao, agenesia total do corpo caloso (ACC) foi identificada em 7 casos, sendo dois associados a Sindrome Alcoolica Fetal (SAF), agenesia parcial do corpo caloso (ACCP) em 7 e hipoplasia do corpo caloso (HCC) em dois. Desempenho intelectual compativel a idade foi detectado em 7 participantes (3 casos de ACC nao associados a SAF e 2 casos com HCC) e 56% da amostra apresentou defiCiência intelectual. O impacto dessas alteracoes cerebrais sobre o desenvolvimento cognitivo e comportamental foi menos grave nos participantes com ACC e HCC em comparacao aos individuos com ACCP. Presenca de ACC associada a sindrome alcoolica fetal esteve associada aos efeitos mais deleterios sobre o desenvolvimento. O maior prejuizo no grupo como um todo envolveu habilidades visoconstrutivas e, na esfera comportamental, a socializacao. As observacoes neurocomportamentais sugerem perfil semelhante ao do transtorno de aprendizagem nao-verbal e foram compativeis a Sindrome da Agenesia Primaria do Corpo Caloso, com a ressalva da grande variabilidade dos casos

O ano de 2013 marca o 70? anivers?rio da descri??o cl?ssica de Leo Kanner sobre o Autismo. Em 1994, na quarta edi??o do Manual Diagnostico e Estat?stico de Transtornos Mentais (DSM), o autismo foi inclu?do em uma nova classe diagn?stica denominada Transtornos Globais do Desenvolvimento (TGD), os quais incluem: o Transtorno Autista, Transtorno de Rett, Transtorno Desintegrativo da Inf?ncia, Transtorno Global do Desenvolvimento sem outra especifica??o e o Transtorno de Asperger. O DSM apresenta crit?rios bem espec?ficos que diferenciam os TGD, no entanto, estudos m?dicos discutem se o Transtorno de Asperger (TA) comp?e o Transtorno Autista, ou se ? qualitativamente distinto. Discute-se a reduzida valida??o emp?rica dos crit?rios diagn?sticos concernentes ao TA. Nessa perspectiva, o DSM ganhou uma quinta e pol?mica revis?o no ano de 2013. A pol?mica mudan?a centra-se na substitui??o de uma an?lise diagn?stica categorial para uma abordagem dimensional, a qual evidencia que a maior parte dos problemas psicopatol?gicos da inf?ncia e adolesc?ncia manifesta-se em um cont?nuo de frequ?ncia e intensidade. Diante da mudan?a na quinta edi??o do DSM, o presente estudo deparou-se com a problem?tica identificada no ?mbito cl?nico e cient?fico, qual seja, a heterogeneidade sintom?tica presente no espectro autista e, por conseguinte, as disson?ncias no estabelecimento de caracter?sticas cl?nicas e neuropsicol?gicas do espectro. Amparado pelo legado te?rico de Luria, buscou-se clarificar o perfil da cogni??o social, comportamento, s?cio afetividade e fun??es executivas em crian?as com diagn?stico de Transtorno Autista e Transtorno de Asperger, conforme crit?rios estabelecidos pelo quarta edi??o revisada do DSM. Para operacionaliza??o dos objetivos propostos, prop?s-se estudo multicasos de seis crian?as. O processo avaliativo foi composto por anamnese com os pais, entrevista com a escola e protocolo avaliativo composto por tarefas qualitativas e instrumentos psicom?tricos. A avalia??o neuropsicol?gica realizada foi guiada pela an?lise cl?nica-processual, conforme pressuposto te?rico de Luria. No tocante aos resultados, foi poss?vel identificar dificuldades nos relacionamentos sociais e no cotidiano escolar das crian?as avaliadas. De modo interdependente, falhas na teoria da mente, nas fun??es executivas e na linguagem versam como principais fragilidades neuropsicol?gicas dos grupos cl?nicos vigentes, notadamente do grupo que comp?e o Transtorno Autista. Os resultados encontrados demonstram que a cogni??o social e a habilidade social est?o altamente relacionadas. Ainda que se reconhe?am as limita??es inerentes ? proposi??o de pesquisas neuropsicol?gicas de vertente cl?nica/s?cio hist?rica, acredita-se que o desenho metodol?gico possibilitou compreender caracter?sticas neuropsicol?gicas das crian?as avaliadas, sem limitar-se ? mera descri??o. Espera-se que pais, profissionais cl?nicos e institui??es sociais, como a escola, compreendam a forma de individua??o do TGD, antes de classificarem ou proporem tratamentos as crian?as

Full textAbstract:
An indirectly heated solar drier fitted with a flat plate collector and a directly heated solar drier were compared with open air sun drying of cocoa beans under field conditions in St. Lucia. Sun drying was conducted on two surfaces, perforated steel and non perforated wood. The methods were examined for the ability to adequately dry fermented beans and effect on quality. Loading rates of 13.5, 26.9 and 40.4 kg/m$ sp2$ were examined.Temperature increases of 15$ sp circ$C and 20$ sp circ$C above ambient were achieved in the indirect and direct drier, respectively. The solar driers were more efficient than sun drying units at removing moisture throughout at loading rates of 26.9 and 40.4 kg/m$ sp2$ but only in the initial stages at 13.5 kg. External mould development was therefore reduced. Open air sun drying on the wooden surface proved more effective in the final stages at 13.5 kg/m$ sp2$.
The dried beans were of similar internal quality despite faster drying in the driers. The various drying methods and loading rates produced beans of similar pH while only loading rates affected titratable acidity differently. The direct solar drier achieved lower final moisture levels at high loads and was the cheaper alternative.

Full textAbstract:
This study investigated the response of the macrophytes in St Lucia Estuary, northern KwaZulu-Natal to drought. The present distribution of vegetation (2010 / 2011) was mapped and changes over time recorded from past aerial photographs. The changes in macrophyte cover in response to environmental factors (sediment and groundwater characteristics) was measured along four transects in 2010 and compared with results from previous years, in 2005 and 2006. In the current study, 1960 images were digitized to illustrate macrophyte distribution and cover of the Narrows, Makakatana and the Eastern Shores during a low rainfall period which started in 1958. The 2001 images were digitized to illustrate vegetation distribution and cover of the same area prior to the current drought which started in June/ July 2002. The 2008 images were digitized to illustrate vegetation distribution and cover of estuarine vegetation within the floodplain during the drought (after 6 years). The sites were visited in June 2011 for verification of the distribution and boundaries of each macrophyte habitat. The area covered by the water column varied over time. In 1960 during a low rainfall period the water was 32705 ha, 33320 ha in 2001 and reduced to 30443 ha in 2008. The area cover of inundated and dry reeds fluctuated with the water level. Under high water levels, low-lying areas such as Fanies Island and Selley‟s Lake were flooded and under low water levels, intertidal sand and mudflats were exposed and colonised by succulent salt marsh (Sarcocornia spp. and Salicornia meyeriana). Similar conditions were observed at Makakatana. Mangroves were observed from the mouth to the Forks. Avicennia marina was the dominant mangrove species and primary colonizer of dredge spoil. The area cover of mangroves in the vicinity of the mouth fluctuated as a result of fluctuating water levels, dredging operations, excavation of the Back Channel and Cyclone Gamede which killed intertidal vegetation. Between 2001 and 2008, mangrove expansion was faster in the Mfolozi Swamps area (± 1.4 ha yr -1) compared to the Narrows (± 0.4 ha yr -1). Long term monitoring transects were set up in 2005, at Makakatana, Charters Creek, Catalina Bay and at Listers Point to document changes in sediment conditions and vegetation cover. These were sampled in July 2005, October 2005, February 2006 and May 2010. Silt was the dominant particle size at Catalina Bay, Charters Creek and Makakatana. At Makakatana, average ground water salinity was 17.2 ± 6.6 ppt, 4.1± 4.9 ppt at Catalina Bay and 32.9 ± 19.3 ppt at Charters Creek. Drought resulted in the accumulation of salt on the surface sediment layer at Listers Point and Charters Creek due to low rainfall. Listers Point, the site with the lowest freshwater input and habitat diversity had the lowest macrophyte species richness with only three species. The dominant species at this site were Sporobolus virginicus and Chenopodium album L. which are highly salt tolerant species. Catalina Bay had the highest species richness (18 to 27); as a result of freshwater input via groundwater seepage from the sand dune aquifers on the Eastern Shores. Along the Eastern Shores, vegetation was dominated by species of Cyperaceae, Juncaceae and Juncaginaceae. Fluctuations in groundwater depth were observed at all sites, Listers Point groundwater depth in February 2006 was 80 cm and the ground water level was not reached during the May 2010 field trip. During the May 2010 field trip, the water column salinity of the St Lucia system was highly variable, Makakatana had the lowest water column salinity of 7.1 ppt, 42.1 ppt at Catalina Bay, 44 ppt at Charters Creek and Listers Point had the highest water column salinity of 95 ppt. An assessment of the changes in macrophyte cover along the transects showed that cover fluctuated in response to rainfall, water level and drought. At Listers Point, there was a continuous decline in the abundance of Sporobolus virginicus over time which was sparsely distributed in the first 40 m of the transect. Sarcocornia natalensis, a succulent and obligate halophyte, was recorded, in areas with high sediment conductivity. In May 2010, bare ground increased to an average percentage cover of 96.5% and was covered with dead organic matter and a salt crust at Listers Point. At Makakatana, there was a significant decrease in bare ground from July 2005 to May 2010 (H = 24.58, N = 197, p<0.001) as bare areas were colonized by salt marsh. Multivariate analysis showed that the abundance of Sporobolus virginicus was positively influenced by sediment moisture content and Paspalum vaginatum abundance was strongly influenced by the water column salinity. At Catalina Bay, low sediment conductivity at the groundwater seepage area resulted in terrestrial vegetation encroaching on estuarine vegetation. Sarcocornia natalensis became more abundant towards the water column. During the period of study, species richness at St Lucia ranged from 2 (Listers Point, May 2010) to 27 (Catalina Bay, February 2006). Salinity and water level fluctuation have a significant impact on the distribution of macrophytes at St Lucia during the drought. In saline areas salt marsh plants have colonized exposed shorelines and along the Eastern Shores groundwater seepage has increased macrophyte species richness. Low water levels have resulted in the exposure and desiccation of submerged macrophytes, which are replaced by macroalgae.

Full textAbstract:
Ten individuals of Cephalopholis cruentata, a marine serranid common on Caribbean coral reefs and important to artisanal reef fisheries, were implanted with acoustic transmitters on two reefs within the Soufriere Marine Management Area, St. Lucia. The mean home range area determined was 2120m2. Home range shape was non-circular, with a mean aspect ratio of 0.72. Neither home range size nor home range shape differed between the study sites or as a function of fish size. However, more active fish, as determined by movement per hour and displacement per hour, had larger home ranges.Use of space within the home range was characterised as activity rates (movement per hour), displacement rates (maximum distance between fish locations per hour), and preferential use of specific areas (% of position fixes in different areas). All fish demonstrated a clear preference for specific areas in their home range. Activity, displacement and % time spent in the preferred reef area were not correlated with fish size. Activity and displacement were higher by night than by day, and consistent with this, fish spent less time in their preferred home range area by night than by day. Given the home range size and movement patterns of C. cruentata determined in the study, the effectiveness of the marine reserve zones in the Soufriere Marine Management Area in protecting C. cruentata is assessed.

Full textAbstract:
The purpose of this research is to study how journalists in two Caribbean countries, Dominica and Saint Lucia, see their profession in a developing country where freedom of the press is high but where restrictions also occur. Through semi-structured in-depth interviews we will ask thirteen local journalists in the aforementioned countries what they think about journalistic values and ask for their thoughts on the journalists´ role and responsibility in society. We will also ask them about what limitations there might be to accomplish these ideals. Since every country differs from another, our study will lean on normative theories, and the study will be based on Hallin and Mancini's work Comparing media systems (2004) and their three models of media. According to the respondents in Saint Lucia and Dominica, the main role for the journalists is to report accurate, balanced and fair stories to the audience so that they can make informed decisions in their everyday life. However, the respondents in both countries face challenges in fulfilling these ideals where in Dominica the main challenge is access to information that prevents the press to work on a free basis. In Saint Lucia the respondents state that main obstacles are the “red tape”, i.e., the problematic bureaucratic procedure, that journalists have to deal with when trying to get information, and also threats such as lawsuits and pulled advertisement - something that prevents them from producing free and independent journalism.Detta är en Minor Field Study finansierad uppsats.

Full textAbstract:
Contrairement à une idée répandue, les questions légales et rituelles sont au centre des préoccupations des kabbalistes. Et, en retour, la littérature halakhique est très loin d'avoir ignoré le discours kabbalistique sur ces questions. Depuis les débuts de la kabbale, voire dans le Talmud déjà, les deux ordres de discours s'interpénétrent. Leur unité organique et la finalité messianique de leur dialectique trouve son expression la plus claire dans l'introduction du 'Ets Hayyim, principal texte de la kabbale lurianique. A la lumière des notions qui y sont exposées, et guidée par le concept de hiérohistoire emprunté à Henry Corbin, cette étude propose une relecture phénoménologique de trois points précis du rituel juif qui ont cristallisé autour d'eux l'essentiel des discussions sur les rapports entre kabbale et halakha. Il en résulte un regard nouveau sur les moteurs métahistoriques et eschatologiques de l'histoire des pratiques religieuses juivesContrary to a well-spread notion, legal and ritual issues are an important focus of kabbalistic discourse and the halakhic literature, in turn, is far from having negleted what the kabbalists had to say. Since the historic beginnings of kabbalah, and even in the Talmud, legal and symbolic discourses interpenetrate. Their organic unity and the messianic telos of their dialectics are best articulated in the introduction to the main text of Lurianic kabbalah, 'Ets Hayyim. In the light of the notions presented therein, and following the concept of hierohistory borrowed from Henry Corbin, this study proposes a phenomenological re-reading of three precise aspects of the Jewish ritual, which have crystallized the essential discussions about the relationship between halakhah and kabbalah. The result is a new outlook on the metahistorical and eschatological motives behind the history of Jewish religious practices

How does music teacher work in class with traditions in the school's world?
I sent out 53 questionnaires to music teacher that works with music in class, in order to find out what the school learn the students about our traditions. When I put together the questionnaires and the background material, I come among other thing until that three fourth dividing off the examined the music teachers do not appear to leave off some folded contained Lucia- and the Christmas tradition. Those music teachers who replied on the questionnaire seem not to notice the immigrant’s traditions.
In this exam work has I also overall and put together background materials, as among other things points on the value of traditions. They are is important by different reasons as for example to create a safe adolescence environment for the pupil.

Full textAbstract:
A decision support framework (DSF) to guide watershed management planning in St. Lucia was developed. The DSF, supported by three components, integrated physiographic criteria in spatially defining sustainable land management regimes, crop suitability based on agro-ecologic zoning criteria, and water quality modelling tools.In the first component, a methodology for agricultural and forestry land management zoning based on decision-rule frameworks was developed, employing GIS-based spatial multiple-criteria integration techniques. Land capability, recommended land management regimes, crop suitability and broad agricultural/forestry land utilization type zones were derived for the country. Sixteen broad agricultural and forestry land utilization types (LUTs) based on FAO agro-ecologic zoning guidelines were spatially defined over the island. These LUT zones represent relative suitability for rain-fed annual and perennial crop production, grazing and forestry.
In the second component, field research to quantify rainfall, runoff and erosion from two small watersheds under contrasting land management regimes was undertaken. Over the study period the erosion rate from an intensively cultivated, degraded agricultural watershed was 20 times that of a completely forested watershed. SCS curve numbers were evaluated for both watersheds based on rainfall-runoff relationships.
The third component demonstrated the application of a distributed-parameter hydrologic/water quality model, AnnAGNPS, in land management scenario evaluation, in terms of runoff and soil erosion. Data from the second component were used to calibrate and validate the model in simulation of daily runoff and erosion losses from the two watersheds over the study period. The model generally performed better in runoff simulation for the agricultural watershed compared to the forested watershed. Average annual erosion rates under current land management regimes were estimated at 73.3 and 7.2 t/ha for the agricultural and forested watersheds respectively. The model was applied to simulate runoff and erosion losses from the agricultural watershed under alternative sustainable land management regimes derived in the first component. Simulated average annual erosion losses were reduced to 9.2 t/ha.
This study demonstrated the application of efficient and powerful computer-based tools in the development of a decision support framework for watershed management planning for small islands.

Full textAbstract:
The purpose of this research was to explore the role of the school principal in St. Lucia in staff development. It also explored whether the role corresponded with the expectations of school teachers.Data was obtained through questionnaires administered to school principals and to school teachers respectively. For the most part, the data was analysed quantitatively. However, a small part of the data was analysed qualitatively using content analysis.
The findings show that generally, school principals play a positive role in staff development and this matches the expectations of teachers. This role takes the form of conducting orientation sessions for new staff, advising staff on teaching techniques, encouraging staff to pursue further studies, inviting their input in school related matters and preparing effective professional development day sessions.

Full textAbstract:
Three soil conservation systems: contour drainage, strip cropping, and terracing, were designed and established within separate plots on hillside farmlands in St. Lucia. A control plot with no form of soil conservation was also established. Topographic and soils surveys of these plots were conducted. Rainfall, runoff and soil loss were measured over one wet season. Crop yields and construction and maintenance costs were also determined.For rainfall amounts between 14.2 and 211.2 mm, runoff depths varied from 0.6 to 203.6 mm in the control plot, 2.1 to 199.2 mm in the contour drained plot, 3.2 to 155.1 mm in the strip cropped plot and 1.3 to 94.7 mm in the terraced plot. The largest amounts of runoff were most often recorded in the strip cropped plot, while on most occasions, the terraced plot produced the least runoff.
Soil loss rates varied from 0.01 to 1.77 kg/ha in the control plot, 0.07 to 16.88 kg/ha in the contour drained plot, 0.2 to 28.86 kg/ha in the strip cropped plot and 0.01 to 6.62 kg/ha in the terraced plot.
Construction costs per hectare were EC$5565 for the contour drainage system, EC $5425 for the strip cropped system and EC$6350 for the terraced system.
Further monitoring of the conservation systems is required for prediction of their long-term effectiveness in runoff and soil erosion control.

Full textAbstract:
Nuestra ciudad está en emergencia urbanamente hace varios años, cada gobierno que pasa genera más problemas y más diferencias en la población cuando la ciudad debería ser más inclusiva.
Este problema es el que hace surgir la UV-U (Unidad Vecinal - Urbana), que se emplazar en esta investigación en la zona antigua de la urbanización San Francisco de la Tablada de Lurín, distrito Villa María del Triunfo. Este barrio es muy antiguo e incoherentemente muy atrasado en su desarrollo urbano. No hay espacios públicos ni equipamiento correcto, no se dan actividades comunales distintas a partidos de fulbito, cada cuatro años en cada gobierno municipal se arreglan las pistas pero estas no duran más de dos años y medio.
La UV-U busca combatir cada uno de los problemas actuales y futuros. Para empezar el problema de vivienda. La población cada día crece más y en los siguientes años excederá por mucho los lotes, al no invertir en infraestructura las personas no tienen otra opción que invadir terrenos. Estos muchas veces pertenecen a áreas protegidas e intangibles por el municipio y se termina dañando el patrimonio cultural de la zona, o en su defecto se asientan en terrenos peligrosos a inundaciones o derrumbamientos. La UV-U se plantea en la parte alta de la ladera plana justo antes de empezar el cerro para convertirse en el nexo entre la vivienda en ladera y la vivienda por invasión dando una solución a estas personas que al no tener una casa bien estructurada terminan por no apropiarse de ella, descuidándola y dejando de lado la comunidad con su entorno.
Otro problema a solucionar es el espacio público. En la actualidad la ciudad no se integra a su entorno, las viviendas no tienen espacios de reunión. Últimamente las multifamiliares de departamentos se hacen más pequeñas y el espacio para la interacción social se reduce a corredores de circulación. La UV-U se generará mediante un espacio urbano que

------------------------------------------------------------------------------------------------------------------------------------------
integrara vivienda – espacio urbano – centro comunal, buscando darle a la población una mejor forma de apropiarse de su vivienda, teniendo el sentido de pertenencia no solo con departamento sino también con su espacio generador de urbanismo. Esta vía peatonal conectara cada bloque de vivienda a la vereda de la calle Vidal y jirón Cuzco, mientras que la calle San Martín será de acceso al centro comunal. Pero la idea del urbanismo en generar actividad para que funcione, por eso la losa deportiva, el comedor, los talleres, biblioteca, auditorios, jardín de niños y el centro comercial irán apareciendo mediante el recorrido del proyecto y según las necesidades del barrio. La actividad social se refuerza con actividades necesarias u opcionales que produzcan sociedad.
La identidad propia del barrio se tendrá en cuenta, dándole el sentido de autoconstrucción para el desarrollo del proyecto y teniendo en cuenta el uso de las azoteas para el cultivo de hortalizas que es realizado en muchas casas del barrio ya que el clima es un punto positivo a usar. Se plantea también darle identidad social mediante el centro comunal y espacios urbanos para así asegurar su uso aunque no se sea propietario de un inmueble.
Se quiere dar un funcionamiento económico y comercial al barrio, para esto se plantea tener un centro comercial en la esquina de calle Vidal con jirón Cuzco, restaurantes a lo largo de la calle Vidal y en jirón Cuzco tener viviendas taller. Aparte cada espacio de ingreso estará flanqueado por pequeños comercios que funcionaran como quioscos, estos se prestan para emprendedores que comienzan la actividad comercial.
El aporte que se da con la tesis va dirigido a la sociedad, comunidad y barrio. Creando un espacio heterogéneo, plural, con calidad de vida y con una diversidad cultural que enriquezca el proyecto. La arquitectura está para generar espacios no para generar ingresos.

After making an observation that young people wish to maintain traditions, but they themselves do not wish to attend, lead to a curiosity to examine if traditions serve any purpose for the young people of today. The discrepancies between that the young people say that it is important to preserve traditions versus that themselves do not wish to participate leads us to believe that traditions fills some kind of function but the question is – What function is this? The purpose of this research is to find out what purpose traditions have for young people and also look for the answer to why young people refrain from participating in certain traditions. The results are built from answers from interviews with 36 young people (19 girls and 17 boys) in the ages of 17 – 19 years old. Theoretical frames that helps answer the questions in this paper are represented by theories from Anthony Giddens, Pierre Bourdieu, Émile Durkheim and Erving Goffman. The results shows that traditions fills the following function, - maintaining social relationships and connections at different times and in different contexts, - contributing to interaction and connectedness, - legitimately be allowed to be family-oriented, - opportunity to provide a desirable appearance and a desired identity. The results also shows that traditions have a function to exclude when a person is not included in a social context The results show that choosing to refrain from participating has to do with that we live in a post–traditional society that opens up opportunities to make choices. Our desire to keep traditions is based on our upbringing and in our habits

O reprogramador neuromuscular Jig de Lucia evita que ocorram interferências oclusais, melhorando assim a avaliação das alterações e distúrbios na oclusão. No presente estudo, foram analisados 42 indivíduos dentados saudáveis, portadores de normo oclusão, respiradores nasais, Classe I de Angle, sem hábitos parafuncionais e disfunção temporomandibular, com a idade entre 21 a 40 anos em ambos os gêneros, com o objetivo de avaliar a atividade eletromiográfica dos músculos masseter e temporal, bilateralmente. Os registros eletromiográficos foram realizados com o eletromiógrafo MyoSystem-Br1. A avaliação foi executada antes da instalação do dispositivo de reprogramação neuromuscular na condição postural de repouso e após a sua instalação sobre dentes incisivos centrais superiores (11 e 21), apresentando contato incisal dos incisivos centrais inferiores na porção palatina do dispositivo nos seguintes períodos de tempo:0, 5 \', 10\', 15 \', 20\' e 30\'(minutos). Os dados foram submetidos à análise estatística (SPSS 17.0) com nível de confiança de 95% (p < 0,05). Os resultados evidenciaram alterações da atividade eletromiográfica dos músculos mastigatórios com o uso do Jig de Lucia nos determinados tempos de estudo da pesquisa, mas não havendo diferença estatisticamente significante para todas as comparações efetuadas. Os autores concluíram que o jig de Lucia altera a atividade eletromiográfica, podendo assim levar a uma reprogramação neuromuscular da mandíbula, muito importante para atividade clínica do cirurgião dentista no diagnóstico correto na posição oclusal.The Lucia\'s Jig neuromuscular reprogramming can eliminate occlusal interferences, thereby improving the evaluation of changes and disturbances in occlusion. In this study, we analyzed 42 healthy dentate subjects, patients with normo-occlusion, nasal breathing, Angle Class I, without deleterious habits and temporomandibular joint dysfunction, with age between 21 to 40 years in both genders, with the aim of evaluating the electromyographic activity of masseter and temporal muscles bilaterally. The electromyographic recordings were performed with the EMG-Br1 Myosystem. The evaluation was performed before placing the device in neuromuscular reprogramming of rest postural condition and after installation in the upper central incisors (11 and 21), incisal one contact the lower central incisor tooth in the palatine portion of the device in following time periods: 0, 5 \', 10\', 15 \'20\' and 30\'(minutes). Data were subjected to statistical analysis (SPSS 17.0) with a confidence level of 95% (p <0.05). The results showed changes in electromyographic activity of masticatory muscles using the Lucia\'s Jig in certain times of the research study, but there was no statistically significant difference for all comparisons. The authors concluded that the Lucia\'s Jig changes electromyographic activity and may thus lead to a neuromuscular reprogramming of the jaw, even very important clinical activity oral surgeon for the correct diagnosis in occlusal position.

Full textAbstract:
O presente trabalho tem por finalidade discutir a leitura que Lucia Miguel Pereira faz de Virginia Woolf em quatro ensaios, Dualidade de Virginia Woolf, Crítica e feminismo, O Big Ben e o carrilhão fantasista e Assombração, nos quais explora aspectos importantes dos ensaios e romances da escritora inglesa. Para Lucia Miguel Pereira, a nova forma do ensaio idealizada por Woolf consiste em uma renovação estética que a distingue de seus predecessores e contemporâneos pela união da linguagem crítica com a narrativa. Denominada de abordagem humanista pela crítica brasileira, a concepção de Woolf possibilita um espaço de criação artística capaz de envolver o leitor e estabelecer uma relação de intensa proximidade com ele. Entretanto, as explicações de natureza estética de Woolf, que congregam mito e movimento feminista para a criação dessa nova forma, são vistas por Pereira mais como resultado de uma visão pessoal da escritora do que como crítica literária propriamente dita. Com relação ao tempo ficcional, seguindo a sugestão de Lucia Miguel Pereira a respeito da necessidade de interação entre tempo cronológico e psicológico no romance, é feita uma leitura comparativa de To the lighthouse e Mrs. Dalloway, de Virginia Woolf, e Amanhecer, da autoria da escritora brasileira, a fim de demonstrar como ambas lidaram com a temporalidade no romance. O fio condutor da análise é a proposta estética de Woolf e o ponto de vista da crítica brasileira.This thesis aims at investigating Lucia Miguel Pereiras reading of Virginia Woolf in four of her articles, Dualidade de Virginia Woolf, Crítica e feminismo, O Big Ben e o carrilhão fantasista, and Assombração, in which she explores key aspects of the English writers essays and novels. According to Lucia Miguel Pereira, Woolfs essays are formally innovative and her renewal of the form distinguishes her from her predecessors and contemporaries. Such differences are reinforced by the simultaneous use of narrative and critical language, which raises the essay to status of an artistic creation, capable of involving the reader by means of an interaction and closeness which Pereira names as a humanistic approach. However, Pereira considers Woolfs explanations of her aesthetics, which include myth and feminism, as resulting much more from her very personal stance than as literary criticism as such. As for fictional time, taking up Lucia Miguel Pereiras suggestion about the necessary interaction between chronological and psychological time in the novel, we compare To the lighthouse and Mrs. Dalloway, by Virginia Woolf, and Amanhecer, by the Brazilian novelist, in order to demonstrate how both writers deal with temporality in the novel, bearing in mind Woolfs aesthetic proposal and the Brazilian critics point of view.

Full textAbstract:
O Jig de Lucia, considerado um reprogramador neuromuscular é um dispositivo confeccionado nos incisivos centrais superiores e, utilizado na clínica odontológica com finalidade de desocluir os dentes e consequentemente desprogramar o padrão de atividade neuromuscular evitando que ocorram interferências oclusais e, assim, possibilitando a melhor manipulação da mandíbula, como também, possibilitando a avaliação das alterações e distúrbios na oclusão dental. No presente estudo, foram analisados 33 indivíduos dentados saudáveis, portadores de disfunção temporomandibular muscular ou mista, respiradores nasais, com a idade entre 21 a 40 anos em ambos os gêneros, com o objetivo de avaliar a atividade eletromiográfica dos músculos masseter e temporal, bilateralmente antes e após a instalação do Jig de Lúcia por meio dos registros eletromiográficos. Para tanto foi utilizado o eletromiógrafo MyoSystem- Br1 e, a avaliação inicial foi executada antes da instalação do dispositivo de reprogramação neuromuscular na condição postural de repouso e após a sua instalação sobre dentes incisivos centrais superiores, apresentando contato da superfície incisal dos incisivos centrais inferiores na porção palatina do dispositivo nos seguintes períodos de tempo: 0, 5, 10, 15, 20 e 30 minutos. Os dados foram submetidos à análise estatística (SPSS 17.0) com nível de confiança de 95% (p < 0,05). Os resultados não mostraram alterações estatisticamente significativas em todas as situações analisadas eletromiograficamente.Lucia Jig, deemed as a neuromuscular re-programmer, is a device manufactured on the upper central incisors and, used in Odontology as a means of disoccluding the teeth and, consequently deprogramming the pattern of neuromuscular activity, avoiding occlusal interferences and, therefore, making it better the manipulation of the jaw, as well as allowing the assessment of dental occlusion alterations and disorders . In the present study, we analyzed 33 healthy dentate subjects, both genders, suffering from muscular or mixed temporomandibular disorder, nasal breathers, between 21 and 40 years old, aiming to assess, bilaterally, the electromyographic activity of the masseter and temporal muscles, before and after the installation of Lucia Jig, by means of electromyographic records. In order to do so, the MyoSystem-Br1 electromyograph was used and, the initial assessment was performed before the installation of the neuromuscular re-programming device, in resting posture condition and after its installation on the upper central incisors, showing contact of the incisal surface of the lower central incisors on the palate portion of the device on the following time periods: 0, 5, 10, 15, 20 and 30 minutes. The data were submitted to statistical analysis ( SPSS 17.0) with 95% confidence level ( p < 0.05). The results showed no statistical significant alterations in all electromyographically analyzed situations.

Neste trabalho apresentamos um assunto que tem contribuído em diversas áreas, o conhecido Problemas de Lurie. Para exemplificar sua aplicabilidade estudamos a Rede Neural de Hopfield e a relacionamos com o problema. Alguns teoremas são apresentados e um dos resultados do Problema de Lurie é aplicado ao modelo de Hopfield.In the present work we show some properties of the so called Luries type equation. We treat particularly the stability conditions problem, and show how this theory is applied in a Hopfield neural network.

A festa ? capaz de intermediar diferen?as sociais e culturais proporcionando novas linguagens entre os seus participantes. A festa religiosa tamb?m tem esta fun??o. Os atos festivos destinados aos santos podem ser incentivadores das novas intera??es sociais ocasionadas pelo evento. Partindo da?, este trabalho pesquisa tr?s festas religiosas que t?m como homenageadas, as santas: Nossa Senhora da Apresenta??o, representando a M?e de Jesus, em Natal, e a hist?ria da funda??o da Cidade, em 1599; Santa Luzia, uma m?rtir da It?lia, faz parte da devo??o popular na cidade de Mossor?, regi?o oeste do Rio Grande do Norte; e Sant Ana, m?e de Maria, ilustra com fervor a cultura caicoense, no Serid? do Rio Grande do Norte. Os objetivos desse estudo foram os seguintes: observar e comparar as festas em quest?o; estudar as festas no Brasil-col?nia; pesquisar as festas do Rio Grande do Norte, relatadas anteriormente, entre os anos de 2007 a 2009; apreender a hagiografia das padroeiras dessas cidades e, por fim, enfatizar os pontos em comuns, assim como as diferen?as existentes entre elas. A inspira??o metodol?gica foi trabalhada a partir de Peter Burke
