Life imprisonment in penological perspective

Hlongwane, Amon Lemmy 11 1900 (has links)
The inmates who are serving life imprisonment are provided with the treatment programmes throughout their incarceration period until they are released from custody. In addition, they are afforded with their primary and secondary needs in prisons. Before the lifers are released from prison, pre-release programmes are presented to them in order to facilitate their reintegration process into the community. After the lifers are released from prisons on parole, the community corrections offices further facilitate their reintegration process into the community. / Penology / D. Litt. et Phil. (Penology)

No. of bitstreams: 0 / Este trabalho apresenta as medidas das taxas de reação nuclear ao longo da direção radial da pastilha combustível por irradiação e posterior espectrometria gama de um fino disco de UO2 com enriquecimento de 4,3% no reator IPEN/MB- 01. A partir de sua irradiação, a taxa de captura radioativa e de fissão foram medidas em função do raio do disco utilizando um detector HPGe. Colimadores de chumbo foram utilizados para esse fim. O disco de UO2 é inserido no interior de uma vareta combustível desmontável e esta é então colocada na posição central do núcleo do reator IPEN/MB-01 e irradiada durante uma hora sob um fluxo de nêutrons de aproximadamente 9 x 108 n/cm2s. Na espectrometria gama, 10 colimadores com diâmetros diferentes foram utilizados, consequentemente, as reações nucleares de captura radioativa que ocorrem nos átomos de 238U e as fissões que ocorrem em ambos 235U e 238U são mensuradas em função de 10 regiões distintas do disco combustível. Correções de eficiência geométrica devido à introdução dos colimadores no sistema de detecção HPGe foram estimados usando o código MCNP-4C. Alguns valores calculados da taxa de reação nuclear de captura radioativa e fissão obtidos pela metodologia de Monte Carlo, utilizando o código MCNP-4C, são apresentados e comparados aos dados experimentais apresentando boa concordância. Além de taxas de reação nuclear, os índices espectrais 28ρ e 25δ foram obtidos para cada raio do disco combustível. / Dissertacao (Mestrado) / IPEN/D / Instituto de Pesquisas Energeticas e Nucleares - IPEN-CNEN/SP

Aperfeiçoamento de métodos estatísticos em modelos de regressão da família exponencial / Further statistical methods in regression models of the exponential family

Alexsandro Bezerra Cavalcanti 03 August 2009 (has links)
Neste trabalho, desenvolvemos três tópicos relacionados a modelos de regressão da família exponencial. No primeiro tópico, obtivemos a matriz de covariância assintótica de ordem $n^$, onde $n$ é o tamanho da amostra, dos estimadores de máxima verossimilhança corrigidos pelo viés de ordem $n^$ em modelos lineares generalizados, considerando o parâmetro de precisão conhecido. No segundo tópico calculamos o coeficiente de assimetria assintótico de ordem n^{-1/2} para a distribuição dos estimadores de máxima verossimilhança dos parâmetros que modelam a média e dos parâmetros de precisão e dispersão em modelos não-lineares da família exponencial, considerando o parâmetro de dispersão desconhecido, porém o mesmo para todas as observações. Finalmente, obtivemos fatores de correção tipo-Bartlett para o teste escore em modelos não-lineares da família exponencial, considerando covariáveis para modelar o parâmetro de dispersão. Avaliamos os resultados obtidos nos três tópicos desenvolvidos por meio de estudos de simulação de Monte Carlo / In this work, we develop three topics related to the exponential family nonlinear regression. First, we obtain the asymptotic covariance matrix of order $n^$, where $n$ is the sample size, for the maximum likelihood estimators corrected by the bias of order $n^$ in generalized linear models, considering the precision parameter known. Second, we calculate an asymptotic formula of order $n^{-1/2}$ for the skewness of the distribution of the maximum likelihood estimators of the mean parameters and of the precision and dispersion parameters in exponential family nonlinear models considering that the dispersion parameter is the same although unknown for all observations. Finally, we obtain Bartlett-type correction factors for the score test in exponential family nonlinear models assuming that the precision parameter is modelled by covariates. Monte Carlo simulation studies are developed to evaluate the results obtained in the three topics.

Correções de auto-interação na teoria do funcional da densidade: investigação em modelos de sistemas de muitos corpos / Self-interaction corrections in density functional theory: investigation in models of many-body systems

Daniel Vieira 26 February 2010 (has links)
Neste trabalho utilizamos sistemas modelos no desenvolvimento, implementação e análise de funcionais orbitais da densidade, focando, em particular, nas correções de autointeração de Perdew-Zunger (PZSIC) e Lundin-Eriksson (LESIC). Aplicamos as correções de auto-interação ao funcional local (LDA) do modelo de Hubbard e de poços quânticos semicondutores, ambos unidimensionais, no caso estático e dependente do tempo, respectivamente. Para o modelo de Hubbard unidimensional, comparamos a LDA, LDA+PZSIC e LDA+LESIC, identificando o desempenho para energias e densidades do estado fundamental, com e sem impurezas locais, além do gap fundamental de energia. Em adição, averiguamos o desempenho diante de cargas fracionárias, estabelecendo conexões com o erro de delocalização da LDA. Mostramos a possibilidade da correta descrição das freqüências das oscilações de Friedel no modelo de Hubbard, além de investigar como a falha da LDA em reproduzir esse aspecto pode estar relacionada com os erros de auto-interação e delocalização. Investigamos ainda as diferentes possibilidades de implementação autoconsistente de qualquer funcional orbital da densidade, analisando a relação entre funcionais aproximados e suas implementações aproximadas. Nos poços quânticos, sob o enfoque dependente do tempo, analisamos a descontinuidade do potencial de troca e correlação ao variarmos o número de partículas, em dois processos distintos: a ionização eletrônica em um poço simples e dissociação de um poço duplo assimétrico. No último caso, avaliamos os efeitos da descontinuidade no número total de partículas em cada poço, revelando os mecanismos que resgatam a neutralidade elétrica durante processos de dissociação, com a correta carga final inteira. / In this work we use model systems to develop, implement and analyse orbital-dependent density functionals, focusing, specifically, on the self-interaction corrections (SICs) of Perdew and Zunger (PZSIC) and of Lundin and Eriksson (LESIC). These self-interaction corrections are applied to the local-density approximation (LDA) for the one-dimensional Hubbard model and for semiconductor quantum wells, in one-dimensional static and time-dependent situations. For the one-dimensional Hubbard model we compare LDA, LDA+PZSIC and LDA+LESIC, and investigate the performance of these approaches for ground-state energies, densities and energy gaps, with and without impurities in the system. We also consider the case of fractional charges, where a connection to the delocalization error of the LDA can be made. We show that in principle a correct description of the frequences of Friedel oscillations in the Hubbard model can be obtained from DFT, and investigate how the failure of the LDA in reproducing this is related to the selfinteraction and delocalization errors. Moreover, we investigate different procedures for the selfconsistent implementation of any orbital-dependent functional, and analyse the question of the interplay between an approximate functional and its approximate implementation. For quantum wells sytems we analyse, in a time-dependent framework, the discontinuity of the exchange-correlation potential under variation of the particle number in two different processes: the ionization of a simple quantum well and the dissociation of an asymmetric double well. In the latter case, we also consider the effect of changes in the particle number in each subwell, thus revealing the mechanism that restores electric neutrality during dissociation, with correct final charge.

Experiences of parents whose children have completed a diversion programme

Mankayi, Andile January 2007 (has links)
The goal of this research study was to explore and describe the experiences of parents whose children have completed the diversion programme in order to make recommendations to probation officers, social workers and people who facilitate the diversion programmes. The study focused on the Youth Empowerment Scheme programme (YES Programme) because it is the diversion programme mostly used in the Eastern Cape. The aim of the programme is to divert young people in trouble with the law away from the criminal justice system and to rehabilitate the young offenders by providing them with essential life skills that can address the offenders’ real problems. In the study the researcher made use of a qualitative research approach in an attempt to explore the experiences of parents whose children have completed the YES programme. The permission of the gatekeeper was sought before the study commenced. The researcher used purposive sampling to recruit participants. Data was collected by means of semi-structured interviews. In analysing the data, the researcher used the steps for qualitative data analysis as stated in Creswell (2003:192). Three main themes along with sub-themes and categories were identified during the process of data analysis. The main findings that emanated from this study were: the seemingly upcoming culture of lack of respect for authority on the part of the youth of today. Another major finding of this study is that the traditional function of families, notably, socialisation of young people within the family structure is on the wane. The recommendations that emanated from this study are: that the YES programme needs to be adjusted to address the specific needs of children that are referred to the YES programme and those of their families and communities. Family life should be strengthened through community development programmes that seek to address family problems of any nature, namely, material, psycho-social, economic, to mention just a few. Community development programmes should address fragile families through community development approaches that are comprehensive and integrated.

Macíková, Nela January 2017 (has links)
This thesis deals with accounting and reporting of selected operations in Equity. The object of interest are three balance sheet items: Reserve fund, Advance for a profit share and Other profit and loss of previous years. The theoretical part is focused on general characteristic of Equity, its basic items and structure of related Financial statements. The indispensable component of this part is also more detailed specification of these three items. Attention is mainly focused to the payments and settlement of advances for a profit share, or accounting view corrections of mistakes from previous years and changes in accounting methods. The practical part is focused on an analysis of the annual reports of the capital companies in 2013-2015. The result is the evaluation of the frequency of occurrence, the use and justification of the analysed items in the annual reports of the companies.

No. of bitstreams: 1 dissertacao_arnaldo_barbosa.pdf: 4326501 bytes, checksum: 074ad9bf93a2808b11dcf8631ded94a4 (MD5) Previous issue date: 2012-03-19 / The broad aim of this dissertation is critically develop a social and legal analysis of the actual, situation of the political system of imprisonment in the penitentiaries of Brazil. Specifically, the focus of the research is directed toward those people who were condemned to imprisonment through long length sentences, due to have been accused and convicted of serious crimes against individuals, the social order and its security. The hypothesis raised here based upon careful empirical observations is that the State, alone, is weak and unprepared to cope with programs of re-socialization of these people; there is no serious academic and educational strategies directed to help them to reach dignity and professional and social respectability; nor have been introduced effective policies toward a professional training, or re-training, in order to integrate them in industrial or commercial activities. By contrast, what has happened is that prisons have frequently be transformed in a web of delinquence, tying, inside and outside the prisons, criminal leaders and their gangs. So, once they leave prison, (when and if they do) they are again engaged in different types of criminal actions. Objectively, this research tries to conceive a new and revolutionary project, on the basis of establishing agreements between state partners and private ones, concentrating both money, social services, and technologies, able to provide educational and professional means and efforts, not only in order to low the level of criminality, but mainly to create new and more effective alternatives to the prisoners to reach moral, social and professional reintegration within the community, as well as regain their citizenship / Esta dissertação dedica-se ao estudo das consequências da aplicabilidade da pena privativa de liberdade e das condições de possibilidade de legitimá-la, através de propósitos ressocializadores. Parte-se do princípio de que a pena carcerária é um mal que ainda se apresenta necessário, e para tanto não merece total extinção, mas sim significativas reformas. Toma-se como base dessa hipótese a desvinculação dos crimes que atingem bens jurídicos de maior relevância e propostas alternativas de encarceramento. Como fundamento, analisa-se os reflexos do encarceramento e suas diferentes propostas, enquanto medida indutora à reincidência, pretendendo sugerir propostas de modificação dos caminhos que provocam o sempre crescente índice de reincidência, embasando-se na participação da sociedade nos processos de reconstrução da dignidade profissional do apenado e do egresso. Nesse contexto, sugere-se que as parcerias entre o poder público e a iniciativa privada haveriam por emprestar ferramentas hábeis a esse desiderato, sugerindo o estudo e a implementação de estratégias que minimizem os efeitos perniciosos da pena convencional. O propósito último é estabelecer processos interativos que liguem a sociedade ao infrator com vista à inclusão desse último à vida social

A study of variables associated with re-arrest among graduates of a juvenile diversion program

Holguin, Eileen Gail, O'Neill, Melody June 01 January 2001 (has links)
The Home Run Program that operates in San Bernardino County was developed to address rehabilitation of high-risk youthful offenders using a Multi-disciplinary Team (MDT) approach to treatment. Despite the fact the program was developed to address recidivism among a delinquent population, recidivism continues to be an issue for participants. This study evaluated specific social and demographic factors and the bearing they had on successful rehabilitation outcome.
