O USO DAS TECNOLOGIAS DA INFORMAÇÃO E COMUNICAÇÃO NO CAMPO OPERACIONAL DA GUARDA CIVIL METROPOLITANA DE SÃO PAULO DESAFIOS À GESTÃO DE PESSOAS

Esta dissertação apresenta um estudo exploratório sobre a experiência de implantação de um sistema digital de segurança. O estudo teve como locus a Guarda Civil Metropolitana de São Paulo e o objetivo geral da pesquisa é analisar o uso das tecnologias da informação e comunicação no campo operacional da organização. Primeiramente foi realizada a pesquisa bibliográfica para rastreamento de temas análogos. Foi possível verificar a escassez de estudos sobre as tecnologias da informação e comunicação na Segurança Pública no Brasil. Dos raros trabalhos encontrados o que deu inspiração para essa pesquisa foi o experimento realizado em Brasília, na área de Gestão do Conhecimento e da Tecnologia da Informação, que investigou a integração de sistemas de info rmações na Segurança Pública do Distrito Federal. Para a realização deste estudo de caso adotou-se a metodologia qualitativa com pesquisas bibliográfica, documental e de campo (entrevistas e observações diretas). Os resultados obtidos demonstram a necessidade de investimentos em tecnologias da informação e comunicação, objetivando a integração e a interoperabilidade das organizações de Segurança Pública. Os resultados também confirmaram os achados em pesquisas e estudos sobre a violência urbana que apontam que só os investimentos na estrutura técnica, em pessoal, em gestão de segurança, chamada política de combate à violência e à criminalidade, não resolve. É preciso urgência na gestão de políticas públicas integradas para combater as causas provocativas da violência e da criminalidade que são a miséria crescente, o desemprego, a falta de serviços públicos eficientes, em especial no setor da saúde e da educação e a ausência de políticas sociais, todos entendidos como violência.(AU)

INDIFERENÇA OU INJUSTIÇA DIVINA? EM BUSCA DE UMA COMPREENSÃO DO SOFRIMENTO HUMANO: UMA EXEGESE DE JÓ 24,7-12

O livro de Jó, cujo tema principal é a dor humana, mostra que as provações que Jó foi obrigado a suportar são absurdas e cruéis. Diante da realidade de sua existência, Jó percebe o universo como uma ausência do Deus em quem crê. A vida humana aparece caótica e as desigualdades sociais não encontram solução, a não ser na morte. Na obra, a explicação a cerca do sofrimento do inocente continuou arbitrária e permaneceu irrespondida. Contudo, a aflição gerada pela miséria total, pelo abandono e pela solidão fez Jó compreender a aflição das pessoas com as quais ele se identificou: o pobre, a viúva, o órfão, o faminto, todos aqueles que de alguma forma sofriam injustamente. Foi a partir dessa identificação que Jó lançou seu grito de protesto e denunciou os crimes cometidos pelos poderosos aos trabalhadores do campo e da cidade na sociedade de sua época, como mostra o capítulo 24,7-12. Jó não desprezou o próximo, nem se omitiu diante da violência contra seres humanos, mas engajou-se no combate do mal. Mal que pode ser entendido como tudo aquilo que contraria o dom mais preciso de Deus, o dom da vida.(AU)

Die Poetik des Extremen. Ausschreitungen einer Sprache des Radikalen:excesses of a language of radical

Gibt es eine Traditionslinie extremistischer Poetiken in der deutschsprachigen Literatur? Uwe Schütte untersucht anhand literarischer Texte ab dem späten 18. Jahrhundert den Konnex zwischen historischen Phänomenen wie Revolution, Krieg oder Terrorismus und extremen biografischen Umständen wie Schizophrenie für die Herausbildung radikaler Schreibweisen. Die Spannbreite der behandelten Autoren reicht dabei von der Klassikertrias Kleist, Hölderlin und Büchner über Schriftsteller des 20. Jahrhunderts wie Ernst Jünger oder Hans Henny Jahnn bis zu den Gegenwartsautoren Ernst Herbeck und Rainald Goetz. The study investigates aesthetic representations of extremism in German-language literature from around 1800 to the present. Its aim is to examine the interplay between three different areas: historical circumstances, (auto)biographical issues, and literary texts. Discussed are texts by both major and marginal writers from various genres, ranging from classics such as Heinrich von Kleist or Friedrich Hölderlin to the marginalised poet Ernst Herbeck or the contemporary writer Rainald Goetz. Subjects and factors considered include extremist phenomena in modern history (such as revolutions, wars, terrorism) and extreme individual experiences (such as suicide or schizophrenia) on the aesthetic domain(s) with regard to the production of literary discourses that could be considered as extremist. These manifest themselves in the development of what can be viewed as ‘radical poetics’, decidedly innovative styles of writing and moral or political transgression in fiction. Being the first critical attempt to trace the history of radical discourses in German literature, the study explores the validity of creating an aesthetic category of 'literary extremism'.

Divergent traditions, converging responses: immigration and integration policy in the UK and Germany

This contribution argues that although the UK and Germany have different historical traditions of immigration and integration, which continue to define policy responses in specific areas, recent developments show a distinct convergence in each country's policy goals and adopted policy instruments in this sector. It contends that both endogenous (demographic and skills shortages, integration deficits) and exogenous (influx of asylum seekers, terrorism) variables can be identified for this convergence. It also pinpoints the European Union as a growing source both of convergence and policy coordination in this field.

Strategies against racism: a comparison of a social movement and case studies of anti-racist policy and practice in the local state

The thesis compares two contrasting strategies employed with the aim of combating particular forms of racism within contemporary Britain. Both are assessed as political strategies in their own right and placed within the broader context of reformist and revolutionary political traditions. The sociology of social movements is examined critically, as are Marxist and post-Marxist writings on the role of human agency within social structures and on the nature of social movements. The history of the Anti Nazi League (ANL) in the late 1970s and its opposition to the National Front is considered as an example of anti-racist social movement based on the Trotskyist model of the United Front. The degree to which the Anti Nazi League corresponded to such a model is analysed as are the potential broader applications for such a strategy. The strategy with which the ANL is compared is the development of anti-racist and equal opportunities policies within local government in the 1980s, primarily by Labour-controlled local authorities. The theory of the local state and the political phenomenon of municipal socialism are discussed, specifically the role of various groups operating in and around local authorities in the formation and implementation of anti-racist policy and practice. Following this general discussion, two case studies in each of the areas of local authority housing, education and employment are explored to consider in depth the problems of specific anti-racist policies. In summation the efficacy of the two strategies are considered as parts of wider political currents in tandem with their declared specific objectives.

An evaluation of certain aspects of an occupational health service

This thesis has been concerned with obtaining evidence to explore the proposition that the provision of occupational health services as arranged at the present time represents a misallocation of resources. The research has been undertaken within the occupational health service of a large Midlands food factory. As the research progressed it became evident that questions were being raised about the nature and scope of occupational health as well as the contribution, in combating danger at work, that occupational health services can make to the health and safety team. These questions have been scrutinized in depth, as they are clearly important, and a resolution of the problem of the definition of occupational health has been proposed. I have taken the approach of attempting to identify specific objectives or benefits of occupational health activities so that it is possible to assess how far these objectives are being achieved. I have looked at three aspects of occupational health; audiometry, physiotherapy and pre-employment medical examinations as these activities embody crucial concepts which are common to all activities in an occupational health programme. A three category classification of occupational health activities is proposed such that the three activities provide examples within each category. These are called personnel therapy, personnel input screening and personnel throughput screening. I conclude that I have not shown audiometry to be cost-effective. My observations of the physiotherapy service lead me to support the suggestion that there is a decline in sickness absence rates due to physiotherapy in industry. With pre-employment medical examinations I have shown that the service is product safety oriented and that benefits are extremely difficult to identify. In regard to the three services studied, in the one factory investigated, and because of the immeasurability of certain activities, I find support for the proposition that the mix of occupational health services as provided at the present time represents a misallocation of resources.

An examination of organisational issues in third sector organisations which undertake nonviolent direct action

This thesis is an examination of organisational issues faced by Third Sector organisations which undertake nonviolent direct action. A case study methodology is employed and data gathered from four organisations: Earth First!; genetiX Snowball; Greenpeace; and Trident Ploughshares. The argument commences with a review of the literature which shows that little is known of the organising of nonviolent direct action. Operational definitions of 'organisation' and 'nonviolent direct action' are drawn from the literature. 'Organisation' is conceptualised using new institutionalism. 'Nonviolent direct action' is conceptualised using new social movement theory. These concepts inform the case study methodology in the choice of case, the organisations selected and the data gathering tools. Most data were gathered by semi-structured interview and participant observation. The research findings result from theory-building arising from thick descriptions of the case in the four organisations. The findings suggest that nonviolent direct action is qualitatively different from terrorism or violence. Although there is much diversity in philosophies of nonviolence, the practice of nonviolent direct action has much in common across the four organisations. The argument is that nonviolent direct action is an institution. The findings also suggest that new institutionalism is a fruitful approach to studies of these organisations. Along with nonviolent direct action, three other institutions are identified: 'rules'; consensus decision-making; and 'affinity groups'. An unanticipated finding is how the four organisations are instances of innovation. Tentative theory is developed which brings together the seemingly incompatible concepts of institutions and innovation. The theory suggests preconditions and then stages in the development of new organisational forms in new social movements: innovation. The three pre-conditions are: the existence of an institutional field; an 'institution-broker' with access to different domains; and a shared 'problem' to resolve. The three stages are: unlocking existing knowledge and practice; bridging different domains of practice or different fields to add, develop or translocate those practices; and establishing those practices within their new combinations or novel locations. Participants are able to move into and between these new organisational forms because they consist of familiar and habitual institutional behaviour.

Revisiting the role stress-commitment relationship:can managerial interventions help?

Purpose: The purpose of this paper is to investigate the moderating influences of empowerment and professional development on role stress-commitment relationships, while examining and confirming the effects of role stress on organisational commitment. Design/methodology/approach: The results are drawn from a cross-sectional survey of 184 front-line employees (FLEs) from a travel service organization. Multiple and moderated regression analyses were employed to test the hypothesised direct and interaction effects. Findings: The results show that role stressors influence affective organizational commitment in FLEs negatively. Role ambiguity did not, unexpectedly, influence continuance commitment positively, but role conflict did. Professional development and empowerment are important management tools that can be used to combat the detrimental effect of role stress on organizational commitment. The paper finds empowerment to be particularly useful in combating the dysfunctional effects of role ambiguity on affective commitment, while professional development is a key tool that helps to combat the dysfunctional effects of role conflict on affective and continuance commitment. However, there are caveats associated with the implementation of these management tools. Practical implications: It is important for management to understand role stress from the FLE perspective, and strategically use intervention tools to help moderate the effects of role stress on organizational commitment components. Originality/value: This study adds further support to the literature that role ambiguity and role conflict should be studied as distinct components of role stress because treating role stress as a single construct may result in suboptimal outcomes for managers, and misleading findings for researchers. In this context, the paper contributes to literature by investigating the moderating impact of empowerment and professional development on the role stress-affective commitment/continuance commitment relationships. The findings suggest that different managerial strategies are required to combat the effect of each of these role stressors on the affective and continuance components of commitment respectively. © Emerald Group Publishing Limited.

Government preparedness:using simulation to prepare for a terrorist attack

The heightened threat of terrorism has caused governments worldwide to plan for responding to large-scale catastrophic incidents. In England the New Dimension Programme supplies equipment, procedures and training to the Fire and Rescue Service to ensure the country's preparedness to respond to a range of major critical incidents. The Fire and Rescue Service is involved partly by virtue of being able to very quickly mobilize a large skilled workforce and specialist equipment. This paper discusses the use of discrete event simulation modeling to understand how a fire and rescue service might position its resources before an incident takes place, to best respond to a combination of different incidents at different locations if they happen. Two models are built for this purpose. The first model deals with mass decontamination of a population following a release of a hazardous substance—aiming to study resource requirements (vehicles, equipment and manpower) necessary to meet performance targets. The second model deals with the allocation of resources across regions—aiming to study cover level and response times, analyzing different allocations of resources, both centralized and decentralized. Contributions to theory and practice in other contexts (e.g. the aftermath of natural disasters such as earthquakes) are outlined.

Identifying the active phase in Cs-promoted MgO nanocatalysts for triglyceride transesterification

Background: Biodiesel is a clean-burning, renewable and biodegradable diesel fuel substitute derived from animal fats and plant oils, which may play an important role in replacing diminishing fossil fuel reserves and combating climate change. Conventional biodiesel production uses soluble base catalysts, such as Na or K alkoxides, to convert oils into fuel, and as a result requires energy intensive aqueous quench cycles to isolate the biodiesel product. Results: Cs-doping nanoparticulate MgO, prepared via a novel, supercritical sol-gel method, yields a solid base catalyst with improved activity for the transesterification of pure triacylglycerides (TAGs) and olive oil. Conclusion: Here, X-ray absorption spectroscopy (XAS) is used to probe the local chemical environment of Cs atoms in order to identify the nature of the catalytically active species as CsMg(CO)(HO). © 2013 Society of Chemical Industry.

Paediatric drug development:reformulation, in vitro, genomic and in vivo evaluation

Angiotensin converting enzyme (ACE) inhibitors lisinopril and ramipril were selected from EMA/480197/2010 and the potassium-sparing diuretic spironolactone was selected from the NHS specials list for November 2011 drug tariff with the view to produce oral liquid formulations providing dosage forms targeting paediatrics. Lisinopril, ramipril and spironolactone were chosen for their interaction with transporter proteins in the small intestine. Formulation limitations such as poor solubility or pH sensitivity needed consideration. Lisinopril was formulated without extensive development as drug and excipients were water soluble. Ramipril and spironolactone are both insoluble in water and strategies combating this were employed. Ramipril was successfully solubilised using low concentrations of acetic acid in a co-solvent system and also via complexation with hydroxypropyl-β-cyclodextrin. A ramipril suspension was produced to take formulation development in a third direction. Spironolactone dosages were too high for solubilisation techniques to be effective so suspensions were developed. A buffer controlled pH for the sensitive drug whilst a precisely balanced surfactant and suspending agent mix provided excellent physical stability. Characterisation, stability profiling and permeability assessment were performed following formulation development. The formulation process highlighted current shortcomings in techniques for taste assessment of pharmaceutical preparations resulting in early stage research into a novel in vitro cell based assay. The formulations developed in the initial phase of the research were used as model formulations investigating microarray application in an in vitro-in vivo correlation for carrier mediated drug absorption. Caco-2 cells were assessed following transport studies for changes in genetic expression of the ATP-binding cassette and solute carrier transporter superfamilies. Findings of which were compared to in vitro and in vivo permeability findings. It was not possible to ascertain a correlation between in vivo drug absorption and the expression of individual genes or even gene families, however there was a correlation (R2 = 0.9934) between the total number of genes with significantly changed expression levels and the predicted human absorption.

Nonlinear inverse synthesis technique for optical links with lumped amplification

The nonlinear inverse synthesis (NIS) method, in which information is encoded directly onto the continuous part of the nonlinear signal spectrum, has been proposed recently as a promising digital signal processing technique for combating fiber nonlinearity impairments. However, because the NIS method is based on the integrability property of the lossless nonlinear Schrödinger equation, the original approach can only be applied directly to optical links with ideal distributed Raman amplification. In this paper, we propose and assess a modified scheme of the NIS method, which can be used effectively in standard optical links with lumped amplifiers, such as, erbium-doped fiber amplifiers (EDFAs). The proposed scheme takes into account the average effect of the fiber loss to obtain an integrable model (lossless path-averaged model) to which the NIS technique is applicable. We found that the error between lossless pathaveraged and lossy models increases linearly with transmission distance and input power (measured in dB). We numerically demonstrate the feasibility of the proposed NIS scheme in a burst mode with orthogonal frequency division multiplexing (OFDM) transmission scheme with advanced modulation formats (e.g., QPSK, 16QAM, and 64QAM), showing a performance improvement up to 3.5 dB; these results are comparable to those achievable with multi-step per span digital backpropagation.

Analogical Reasoning Techniques in Intelligent Counterterrorism Systems

The paper develops a set of ideas and techniques supporting analogical reasoning throughout the life-cycle of terrorist acts. Implementation of these ideas and techniques can enhance the intellectual level of computer-based systems for a wide range of personnel dealing with various aspects of the problem of terrorism and its effects. The method combines techniques of structure-sensitive distributed representations in the framework of Associative-Projective Neural Networks, and knowledge obtained through the progress in analogical reasoning, in particular the Structure Mapping Theory. The impact of these analogical reasoning tools on the efforts to minimize the effects of terrorist acts on civilian population is expected by facilitating knowledge acquisition and formation of terrorism-related knowledge bases, as well as supporting the processes of analysis, decision making, and reasoning with those knowledge bases for users at various levels of expertise before, during, and after terrorist acts.

Criminals and terrorists in partnership:unholy alliance

The nexus between terrorism and organised crime consists in a strategic alliance between two non-state actors, able to exploit illegal markets, threaten the security of individuals, and influence policy-making on a global level. Recent Europol reports have pointed towards the importance of studying the links between organised crime and terrorist groups, and have underlined that the nature and extent of these connections have seldom been addressed from an academic perspective. Considering the degree of dangerousness that both organised crime and terrorism currently represent in the world, the collusion between these two phenomena is of urgent contemporary interest. Basing itself on geographical case-studies, this edited volume aims at contributing to the existing literature in three ways: by enriching the empirical knowledge on the nature of the crime-terror nexus and its evolution; by exploring the impact of the nexus within different economic, political and societal contexts; and by expanding on its theoretical conceptualization.

Fibre impairment compensation using artificial neural network equalizer for high-capacity coherent optical OFDM signals

We propose an artificial neural network (ANN) equalizer for transmission performance enhancement of coherent optical OFDM (C-OOFDM) signals. The ANN equalizer showed more efficiency in combating both chromatic dispersion (CD) and single-mode fibre (SMF)-induced non-linearities compared to the least mean square (LMS). The equalizer can offer a 1.5 dB improvement in optical signal-to-noise ratio (OSNR) compared to LMS algorithm for 40 Gbit/s C-OOFDM signals when considering only CD. It is also revealed that ANN can double the transmission distance up to 320 km of SMF compared to the case of LMS, providing a nonlinearity tolerance improvement of ∼0.7 dB OSNR.
