Atrás das grades: redes sociais, habitus e interação social no sistema carcerário do RN

Esta tesis trata de discutir y entender los diversos tipos de redes sociales y formas de interacción social presentes en el sistema penitenciario de Rio Grande do Norte. Nuestro problema se basa en un incremento significativo en las tasas de encarcelamiento y la prisión en Brasil y el mundo en los últimos diez años. Asimismo, la aparición del crimen organizado ya, en cierta medida, el control de las prisiones brasileñas, como el Comando Vermelho (CV) y el Primeiro Comando da Capital (PCC), una consecuencia directa de las terribles condiciones de las prisiones de Brasil y aumento de la violencia y el crimen en nuestro país. Para resolver el problema, se optó por utilizar las categorías de análisis de Michel Foucault (prisión y la disciplina), Pierre Bourdieu (habitus y campo), Ervirng Goffman (institución total, de interacción, de fachada y de equipo) y Mark Granovetter, Ricardo Abramovay e João Peixoto, entre otros, la nueva sociología económica (Redes, nodos y lazos) como principal apoyo. También construyó una revisión histórica de la cárcel en Brasil y Rio Grande do Norte hasta llegar al objeto. Esto, en términos de investigación cualitativa, se sumergió en el mundo de las prisiones Dr. Francisco Nogueira Fernandes, conocido como Penitenciario de Alcaçuz, ubicado en el municipio de Nísia Bosque, Rio Grande do Norte. Penitenciaría del Estado de origen, las casas de Alcaçuz seiscientos cuarenta y tres reclusos, divididos en cinco pabellones, un total de ciento cuarenta y siete células. Mediante la observación sistemática y la entrevista cualitativa s semi-estructurada como las principales fuentes de recopilación de datos, hemos tratado de explicar el universo que acabamos de analizar por las Ciencias Sociales. Nos dimos cuenta de que, para cumplir con la escena nacional, regaliz viola de manera flagrante lo que se denomina en la Constitución de 1988 y LEP (Ley de Ejecución Penal), sin tener en cuenta los derechos de los individuos a una porción de una oración con un mínimo de dignidad. Se ha demostrado que las personas que permean el universo proviene de un ambiente de la prisión, la sociabilidad violenta, sedo también tienen un habitus precario. La prisión, espacio disciplinario y un tipo específico de interacción social marcada por el control, contribuye a la profundización de habitus, pero que muestra que no es también como un espacio cerrado en absoluto, sino un lugar donde penetran las redes y dinámicas muy social. Al mismo tiempo, se encontró que más de la presencia de "grupos organizados" es el espacio en las cárceles para la interacción social y las redes sociales que pasan dentro y fuera de su espacio

O direito à informação jornalística: garantias constitucionais ao direito de ser informado no sistema brasileiro.

The freedom of social communication referred to those freedoms exercised under of the media. The journalism is professional activity responsible for factual information, real, pluralistic and of the public interest, directed diffusely to social orientation. The right of the information, characterized as diffuse right or of fruition by uncertain and numerous holders, is subdivided in the right of the inform, inform yourself and right to be informed. The journalists, as occupants of a enlarged spectrum concerning of right of the inform, have responsibility for the information they disseminate, devoir that puts on the basis of the constitutional right to be informed. This duty is divided with journalistic companies, when them realized. In the research, examined the existence of constitutional guarantees the right to be informed. To answer the question, realized research to support bibliographical and documentary. The guaranty is a empirical preoccupation coated with legality, since lends itself effect concretize a right. Traced so a panel of guarantees of institutional imprint, substantive and procedural. Treating of the institutional guarantees the right to information, it would refer to true institutions (as the free press) and may begin subjective rights. In the case of substantial guarantees, we would have access to information, the confidentiality of the fonts and the incensurable feature of journalistic information. A guarantee peculiar would be constitution of bodies responsible for monitoring the quality of the vehicles of communication. Trace it also a panel strict of procedural safeguards, such as public civil action, the security s warrant, and the rights of petition and answer.

Ativismo judicial e materialização das políticas públicas infanto-juvenis na constituição da república: Fixação de planos ideais de atuação para os atores do Sistema de Garantia de Direitos (SGD)

The research arose from the necessity of showing ways to be followed by the actors of the System Guaranteeing Rights of the Child and Adolescent (SGD), regarding the implementation of rights for young people, because the legislation in force in Brazil is currently considered a model around the world and, paradoxically, the fundamental rights of children and adolescents are not met, even with the constitutionally guaranteed priority. Thus, the study investigates the fundamentality rights for young people, enshrined in the Constitution of the Republic, as well as the ways of effectiveness of these rights through the actions of actors of the System Guaranteeing Rights, especially the judiciary. Focusing realized, studying theories of fundamental rights, especially Structuring a Theory of Law (Strukturiende Rechtslehre), Friedrich Müller, who emphasizes the need for analysis of social reality in the application of the rule of law. Study also the public budget and public policies concerning children and adolescents, with emphasis on preparation of budget laws and the process of discussion, deliberation, choice and implementation of public policies for children and teenagers. It then presents the typical functions of the members of System Guaranteeing Rights, as well as prepare a plan for optimum performance for each of the actors, with emphasis on analysis of the implementation of public policies at the municipal level. Finally, it analyzes the theory of separation of three powers, and discusses the positive and negative factors for judicial intervention, concluding that the Courts can consider the action activist, from finding the omission of the Executive and legislative branches, as regards the implementation of the rights of children and adolescents, as well as the rights of children and young people are not realized in most cases, due to the omission of actors of the System Guaranteeing Rights

A investigação criminal e a vedação ao anonimato no sistema jurídico brasileiro

The thesis, prepared with basis on deductive reasoning (through the utilization of general concepts of the fundamental rights theory) and on inductive logic (by means of the consideration of particular situations in which the theme has been approached) deals with the criminal investigation and the prohibition of anonymity in the Brazilian law system. The state criminal investigation activity presents not only a substantial constitutional basis, due to the objective dimension of fundamental rights (which imposes an obligation to protect these essential values), but also a formal constitutional basis, arising from the administrative principles of rule of law, morality and efficiency, referred to in article 37 of the Constitution. The criminal investigation, however, is not an unlimited pursuit, being restrained by the duty to consider fundamental rights that oppose to its realization. One of the limits of the state investigation activity, in the Brazilian law system, is the prohibition of anonymity, referred to in article 5°, IV, of the Constitution. This prohibition is a direct constitutional restriction to the freedom of expression that aims to ensure the credibility of the diffusion of ideas and prevent the abusive exercise of this fundamental right, which could harm both persons and the state, with no possibility of punishment to the offending party. Generally, based on this prohibition, it is affirmed that a criminal investigation cannot begin and progress founded on anonymous communication of crimes. Informations about crimes to the investigative authorities require the correct identification of the stakeholders. Therefore, it is sustained that the prohibition of anonymity also comprehends the prohibition of utilization of pseudonyms and heteronyms. The main purpose of this essay is to recognize the limits and possibilities in starting and conducting criminal investigations based on communication of crimes made by unidentified persons, behind the veil of anonymity or hidden by pseudonyms or heteronyms. Although the prohibition of article 5°, IV, of the Constitution is not submitted to direct or indirect constitutional restrictions, this impediment can be object of mitigation in certain cases, in attention to the constitutional values that support state investigation. The pertinence analysis of the restrictions to the constitutional anonymity prohibition must consider the proportionality, integrated by the partial elements of adequacy, necessity and strict sense proportionality. The criminal investigation is a means to achieve a purpose, the protection of fundamental rights, because the disclosure of facts, through the investigatory activity, gives rise to the accomplishment of measures in order to prevent or punish the violations eventually verified. So, the start and the development of the state criminal investigation activity, based on a crime communication carried out by an unidentified person, will depend on the demonstration that the setting up and continuity of an investigation procedure, in each case, are an adequate, necessary and (in a strict sense) proportional means to the protection of fundamental rights

O sistema de certificação do etanol brasileiro sob a ótica do princípio constitucional do desenvolvimento sustentável

The gradual inclusion of biofuels is a necessary change that countries must include in their energy mixes. Energy sources still widely used in the world, such as oil and coal, are endowed with a high pollution load to the environment, bringing damages to the water, to the air and to humans as well. In addition, although there are conflicting studies, they are also identified as major causes of the greenhouse effect and the global warming phenomenon. They are, moreover, finite sources of energy, given that its reserves will surely run out. However, even if the introduction of biofuels, such as ethanol, in the energy mix is crucial for the survival of the present and future populations, this insertion cannot settle so disorderly and, thus, one must ensure the quality of these resources and promote transparency in international trade. In this manner, a certification process for ethanol is essential to attest that this biofuel meets the sustainable requirements defined for its production. Hence, this study sought to address the importance of the adoption of certification in the ethanol industry, according to the principle of sustainable development, by analyzing the evolution of its concept, its combination with the fundamental objectives sculptured in the Constitution of 1988, its regulation under Brazilian laws and the need for a balance between economic activities and the mentioned principle. The work also encompassed the criteria used to establish certification standards and their participating actors, combined with a study of ongoing initiatives. Finally, the consequences of the adoption of a certification process for ethanol in Brazil were presented, both in terms of sustainable development and in international trade

Justiça restaurativa no sistema penal e processual penal como forma de concretização do estado democrático constitucional

Diante do atual modelo penal e processual penal não atender aos reclamos das partes interessadas, gerando um descrédito na Justiça de um modo geral, surge a Justiça Restaurativa como uma alternativa para solucionar tais problemas e como elemento de concretização do Estado Democrático Constitucional. A Constituição Federal de 1988 representa o símbolo maior do processo de democratização e de constitucionalização nacional. O Princípio da Dignidade da Pessoa contida no texto constitucional consiste num dos principais fundamentos da República Federativa do Brasil, funcionando como respaldo aos direitos e garantias fundamentais do cidadão, sobretudo na seara criminal. A partir do processo de constitucionalização nacional, ocorre uma releitura das legislações infra-constitucionais, que passam a ser interpretadas de acordo com o texto constitucional. Atualmente, a conjuntura jurídico-penal pátria está associada à ideia de garantismo, ligada ao conceito de Estado Democrático Constitucional. Apresenta-se a Justiça Restaurativa como um novo modelo de Justiça Penal, mais flexível e humanizado, visando além da aplicação da pena imposta pelo Estado, superar uma situação de conflito, na busca por resultados positivos no combate e redução da criminalidade, a satisfação da vítima e a mudança da cultura de violência, compatível com as diretrizes do Estado Democrático Constitucional. A partir da análise do direito internacional e de projetos e legislações nacionais envolvendo a Justiça Restaurativa, percebe-se a eficácia das medidas restaurativas na solução de conflitos dentro do Processo Penal, além da satisfação da vítima, do infrator e de familiares na participação dos encontros restaurativos, constituindo ferramenta de satisfação da dignidade humana, dentro de uma perspectiva humanista e garantista

Sistema eleitoral proporcional : uma proposta técnico-politica para o Brasil

The present work aims to analyze the several proportional electoral systems from the contemporaries democracies in order to, in the end, purpose a system that better fits to the constitutional Brazilian order. In this direction, we pursued to indicate the main virtues and imperfections in proportional electoral systems in use in more than two hundred countries, especially relating to the positive and negative effects that these systems inject in the party systems, in the governability and in the representativity. In order to collect elements, and also before getting to the work s main point, other issues were approached, even in a shortened way. Nevertheless, in a position taking, we conclude the work opting for a proportional electoral system that potencializes the constitutional principles of representativity and governability as well as prints a party system strong and strict, once these are the depositaries of a democracy compromised with the Brazilian society

Decomposição de culturas de cobertura no sistema plantio direto, manejadas mecânica e quimicamente

O sistema plantio direto preconiza o uso de culturas de cobertura para produção de massa seca sobre o solo. O presente trabalho teve por objetivo estudar a produção e a taxa de decomposição de duas coberturas vegetais - crotalária juncea (Crotalária juncea L.) e mucuna-cinza (Stilozobium niveum L) - em três sistemas de manejo (rolo-faca, triturador de palhas e herbicida), e a capacidade de campo efetiva dos manejos. O experimento foi realizado na área do Laboratório de Máquinas e Mecanização Agrícola (LAMMA), do Departamento de Engenharia Rural, UNESP, Jaboticabal - SP, com delineamento em blocos ao acaso, em esquema fatorial 3x2, originando seis tratamentos, com quatro repetições. Foram analisadas as produções de massa seca das culturas de cobertura antes e após o manejo, a velocidade de deslocamento e a capacidade de campo efetiva para cada conjunto (trator-equipamento). As análises dos valores obtidos permitiram verificar que o fator manejo não interfere na decomposição da massa seca das coberturas vegetais e que as duas culturas de cobertura apresentaram massas semelhantes aos 30; 70 e 125 dias após a semeadura, diferindo aos 97 dias, época na qual a crotalária apresentou maior quantidade de massa seca. Aos 30; 51 e 71 dias após o manejo, as massas secas das culturas foram semelhantes. O manejo com herbicida apresentou maior capacidade de campo efetiva.

Desempenho de cultivares de alface crespa em dois ambientes de cultivo em sistema hidropônico

Este trabalho foi desenvolvido em Ribeirão Preto-SP, de 06/02 a 07/04 de 2006. O objetivo foi avaliar o desempenho de cinco cultivares de alface (Pira Roxa, Belíssima, Locarno, Crespona Gigante e Verônica) em dois ambientes de cultivo (casa de vegetação climatizada e não climatizada) em sistema hidropônico NFT. O delineamento experimental foi em blocos casualizados para cada ambiente com três repetições sendo cinco cultivares. Os ambientes foram comparados por meio de análise conjunta. Avaliaram-se a massa fresca e seca da parte aérea, massas fresca e seca do caule, massa fresca e seca da raiz, número de folhas maiores que 10 cm e número total de folhas. Não houve efeito significativo da interação cultivares e ambientes, demonstrando que as cultivares tiveram comportamento similar em ambos os ambientes.

Crescimento econômico e restrição externa da economia brasileira: uma análise do padrão das exportações em relação ao BRIC e do Sistema de Inovação do Brasil (1980-2012)

This Master s Thesis aims to use the theoretical models of growth with restricted balance of payments, specifically Kaldor (1970) and Thirlwall (1979) models, to analyze the behavior and the pattern of specialization of Brazilian exports and imports in the last years. It is observed that, in some periods, the pattern of specialization has contributed in restricting long-term growth of the Brazilian economy. It has been hypothesized that overall this is due to lack of structural transformation policies. To achieve this goal, it analyzed the performance of Brazilian exports and imports disaggregating them according to their technological content. The basis for comparison was a group of countries to which Brazil is inserted in, the BRIC. In this regard, the work is a comparative analysis by using descriptive statistics. It is concluded that the low rate of GDP growth experienced by Brazil since the 1980s can be explained in part by the decoupling of the Brazilian National Innovation System (NIS) and the Brazilian productive structure. This would be reducing the income elasticity of exports and raising imports, causing a pattern of specialization intensive primary commodities and labor and low-skill labor

Declínio dos citros: algo a ver com o sistema de produção de mudas cítricas?

Na atualidade, a citricultura paulista enfrenta sérios problemas com o surgimento de novas enfermidades limitantes ao processo produtivo. Uma das alternativas para prevenir essas enfermidades é, seguramente, a produção de mudas certificadas, com borbulhas e sementes de assegurada qualidade genética e sanitária, produzidas em containers ou sacos plásticos, sob fiscalização dos órgãos competentes, garantindo-se, assim, a sanidade das mesmas. No entanto, tem-se verificado que grande parte do processo operacional de produção de mudas cítricas foi parcialmente adaptado da produção de essências florestais (eucalipto), onde se insere, principalmente, o emprego de tubetes com comprimento de 12 cm. Tal prática desencadeia uma grave deformidade morfológica no sistema radical das mudas cítricas, reduzindo o seu potencial de crescimento, quando são plantadas a campo, em local definitivo. Como a principal causa desencadeadora do declínio dos citros parece ser o estresse hídrico, plantas oriundas desse sistema de produção de mudas, mostram-se muito mais vulneráveis ao estresse e, conseqüentemente, a esta anomalia. Como atualmente todas as mudas produzidas no Estado de São Paulo provêm desse sistema de produção, seguramente o declínio dos citros tenderá a ser, futuramente, muito mais freqüente e severo nos casos de combinações vulneráveis à sua ocorrência.

O processo avaliativo institucional de desempenho do sistema público municipal de Teresina-PI (2001 a 2005): entre a lógica da excelência e a lógica da aprendizagem

This work focalize the institutional and educational evaluation, aiming to investigate the Municipal System Institutional Evaluation Performance of Teresina City Piauí (2001-2005), and to reflect about Institutional System Performance and its contribution to compose a new learning evaluation practice. In this sense, classifies elements about the evaluation practice in two Elementary Education municipal public schools, involving Education Municipal Bureau technicians as managers, pedagogues, teachers and students. Based on the ethnographic studies principles in the educational area, the work employs investigative procedures like document analysis, interviews with groups and individuals and also participator s comments. Intending to comprehend the complexity produced by the institutional and education evaluation processes, the wok reveals the Institutional Evaluation legal and educational political basis and the several positions assumed by the Learning Evaluation, as a classification tool or as a learning enhancement. This work points, as results, to a evaluation culture bipolarity carried out by the Municipal Education System as a explicit control and regulation toll, related to the classification and learning in a interaction process that operates both in the pressure and the reflection, as a culture practice established between excellence of logic and learning. The evaluation history has been construct on the evaluation actions dialectics, joint simultaneously between the Institutional Evaluation Performance and the learning evaluation. The senses, meanings and actions bipolarity is a interaction process product sustained between the institutional evaluation, under the scholar ranking application, and the learning evaluation. In this relativity, the teacher evaluation practice is found, ruled by interesting, thoughts and actions on the school evaluation, allowing a higher security and support to the learning results. Grounded in the researched reality, its possible to say that the teacher s evaluation practice is diversified, with different characteristics, when it is done in the learning search and in the learning intention. In the first case, reflects, rearranges and constructs new actions that lead the student to produce learning. In the second, shows the will, the wish of learning, but is a weak action, producing a not really significant learning and development; as a result, remains the mark approach as a determinant in the student future. The work s hope is to contribute not just to rethink these two evaluations dimensions the institutional and the learning ones but also to organize the school and to improve the pedagogic process

Efeito de herbicidas residuais, aplicados por vários anos consecutivos, na distribuição do sistema radicular da laranjeira Natal (Citrus sinensis.(L.) osbeck)

O presente trabalho foi desenvolvido com o objetivo de verificar a influência do uso contínuo de vários herbicidas residuais, sobre a distribuição das radicelas de laranjeiras Natal (Citrus sinensis (L.) Osbeck) enxertadas sobre limão Cravo (Cithus limonia Osbeck) e plantadas em janeiro de 1970. O experimento foi instalado no pomar de produção da Faculdade de Ciências Agrárias e Veterinárias do Campus de Jaboticabal (UNESP), em Latossol Roxo distrófico, com 1,6% de matéria orgânica e 51% de argila. O delineamento experimental utilizado foi o de blocos ao acaso, dentro de um esquema fatorial 11x 3x2x2, com três repetições. Os tratamentos utilizados, com as respectivas doses em kg do i.a/ha foram: fluometuron a 4,2; simazíne a 4,8; atrazine a 4,8; bromacil a 3,2;bromacil (40%) + diuron (40%) a 4,8; bromacil (53,3%) + diuron (27,6%) a 4,8; terbacil a 3,2; oxadiazon a 1,5; dichlobenil a 3,0 e 6,0; além de uma testemunha capinada. O estudo das radicel as foi feito pelo método do trado, tendo sido tomadas amostras de solo contendo radicelas, nas distâncias de 80, 160 e 240 cm do tronco, nas camadas de 0 a 15 cm e 15 a 30 cm de profundidade e em duas direções distintas (entrelinhas e entreplantas). Os resultados mostraram que as radicelas localizam-se superficialmente, com 70% delas nos primeiros 15 cm, do total encontrado na camada superficial de 0 a 30 cm de profundidade do solo. Cerca de 75% das radicelas situam-se até a distância de 160 cm do tronco. Na camada mais superficial do solo (0 a 15 cm), a quantidade de radicelas diminuiu de maneira acentuada, à medida que se afastou do tronco. Na camada de 15 a 30 cm de profundidade, ocorreu uma distribuição horizontal mais uniforme, comparada com a da camada de 0 a 15 cm. As radicelas das plantas do cultivar Natal distribuiram-se uniformemente, tanto na direção das plantas da linha vizinha, quanto nas das plantas de uma mesma linha, para o espaçamento de 7,0 m x 7,2 m. Não se detectaram diferenças estatisticamente significativas nas quantidades de radicelas entre as parcelas dos vários tratamentos com herbicidas, excluindo-se desta forma, qualquer efeito negativo de tais produtos químicos sobre o sistema radicular das laranjeiras.

O dia mais feliz da minha vida: a entrada na universidade segundo os alunos recém-ingressos no curso de Pedagogia da UFRN(2004.1)

The present work, based on the methodological principles of the Comprehensive Discourse Analysis, aimed, through the speech of twelve newly arrived students at the Pedagogy course of the Federal University of Rio Grande do Norte, to understand the moment students start university. It also aimed to analyze the relationship between the schools they were coming from and university entrance as well as the relationship between university and their new students. In the first part of the work, which focused on school knowledge, a comprehensive listening of the speeches of the students led primarily to a distinction, established by the students, between public and private schools, a distinction especially based on the view of superiority of private schools against public ones. The abovementioned interpretation is found in the discussion of the structural duality of Brazilian education which, historically, offers different pedagogical appliances among students of more priviledged social classes and those who come from lower levels of society. The overcome of this duality, aspired by the Brazilian Constitution of 1988, was stopped by the advent of a new economic model neoliberalism, which reinforced the differences between public and private when it prioritized the market on the economic, political and social relations, including educational projects. Impoverishment of public institutions and pauperization of the work of professors affected also the relationship between teachers and studens at the current institution. This is how the teacher becomes the greatest villain at the public management system. All of these references concerning differences in the quality of teaching at public and private schools, expressed by the students interviewed, however, were centered in the preparation for the entrance exam, called vestibular, thus showing a view that the relationship between the student and the school he came from is of a propedeutic kind and even so, reduced to a preparation for an entrance exam. In the second part of the work, which analyzed the relationship between newly arrived students and their university, it was noticed that the latter represents a whole new world. This world is seen as the change at the student´s social statute for now he is grown, takes more responsibilities and is socially respected. This change of attitude established by society and the discovery of a new world which requires more independence from the students, creates in them feelings of pride and fear and they feel insecure when it comes to making decision in the campus because now their decisions deliver a greater load of responsibility. This is when students understand they need to develop autonomy, which is seen, in this work, as the capacity to make conscious decisions. Nevertheless students expressed an understanding of autonomy as something that comes as a gift for those who enter university and not as a process that is constructed from social experiences. For these students, the need to be autonomous refers to the relationships with their teachers and the search for information. This search, however, is also related, according to interviews, to public school financial cuts, which penalize university, and to the lack of employers

Representações sociais de discentes sobre universidade: um estudo psicossocial entre ingressantes do vestibular e da seleção ProUni

Demand for access to higher education to put in test the education Brazilian system in view of the surplus of selective processes of public universities, people without option to pay their studies at this education level. In this context, it has arisen the University for All(Universidade para Todos)Program, the ProUni, from Ministry of Education - MEC, created by the Federal Government in 2004, and that it aims the granting of full and partial scholarships in private higher education institutions, graduate courses in sequential specific training, low-income Brazilians students who do not have higher-level degree. Created by the Provisional Measure No 213/2004 and institutionalized by Law No. 11096 of January 13, 2005, the ProUni offers, however, the exemption of some taxes to those institutions that join the program. This is one of the privileged time for the study of Social Representations by offering the researcher, a living laboratory, natural environment, the confrontation between the established and new. In time like this people are challenged to incorporate the new system to the pre-existing one, aiming it through a strangeness of what was so familiar. It is through this game of social forces that we developed the present study with 196 entering higher education, of these are 116 of selective vestibular system and 80 of the ProUni selective system. We opt by the procedures for data collection in order to have access to the circulating senses, in addition to the streamlined responses. With foundation in Abric, we perform the test the Free Association of Words, then analysed by the software and by EVOC Content of the type theme as Bardin. Besides, we require of the subjects, a writing on the study object university later analysed by the software ALCESTE. The results point out to a representation strongly rooted in social factors such as more traditional socio-cultural elements: the beliefs, values, the symbols. It is unique in both groups of subjects: among those entering by the selective ProUni system, there was a stronger anchor in that it does not make inquiries about the program. At the same time, there is a stronger presence of objectivation, entering the selective vestibular system in order that they explained with a value judgement on the programme. It is suggested further studies considering the embryonic state of social representation, as recent as the social purpose that triggered. It would be relevant even the replication of the same research with other people in order to strengthen the power of the theorising of empiria available
