Metaphors in complexity theory and planning

This article reviews the use of complexity theory in planning theory using the theory of metaphors for theory transfer and theory construction. The introduction to the article presents the author's positioning of planning theory. The first section thereafter provides a general background of the trajectory of development of complexity theory and discusses the rationale of using the theory of metaphors for evaluating the use of complexity theory in planning. The second section introduces the workings of metaphors in general and theory-constructing metaphors in particular, drawing out an understanding of how to proceed with an evaluative approach towards an analysis of the use of complexity theory in planning. The third section presents two case studies – reviews of two articles – to illustrate how the framework might be employed. It then discusses the implications of the evaluation for the question ‘can complexity theory contribute to planning?’ The concluding section discusses the employment of the ‘theory of metaphors’ for evaluating theory transfer and draws out normative suggestions for engaging in theory transfer using the metaphorical route.

If the British left: agricultural policy outside the CAP?

If the Conservative party wins Britain’s General Election in 2015 the incoming Government intends to negotiate a new settlement with the EU, and then hold an in-out referendum. Opinion polls suggest a narrow majority would vote to leave. To exercise an informed choice the electorate would need to know what feasible alternatives are available, so that these can be assessed and debated. Furthermore, in the event of a no vote the Government must be ready to implement its alternative strategy: Plan B. This implies that both a new EU settlement, and Plan B, need to be negotiated concurrently. There has been no serious attempt to explain what Plan B would mean for UK farm policy. Would, for example, British farmers continue to receive the level of support that they currently enjoy; would support be more focussed on environmental objectives? WTO rules on most-favoured-nation treatment and regional trade agreements would apply. Could a WTO compatible agri-food trade agreement be negotiated with its former EU partners, or would Irish and Brazilian beef face the same tariff barriers on imports into the British market? For the EU, the loss of a major net contributor to EU finances could result in a re-examination of the CAP budget.

The stability and aggregation properties of the GTPase domain from human SEPT4

The septins are a family of conserved proteins involved in cytokinesis and cortical organization. An increasing amount of data implicates different septins in diverse pathological conditions including neurodegenerative disorders, neoplasia and infections. Human SEPT4 is a member of this family and its tissue-specific ectopic expression profile in colorectal and urologic cancer makes it a useful diagnostic biomarker. Thermal unfolding of the GTPase domain of SEPT4 (SEPT4-G) revealed an unfolding intermediate which rapidly aggregates into amyloid-like fibers under physiological conditions. In this study, we examined the effects of protein concentration, pH and metals ions on the aggregation process of recombinant SEPT4-G using a series of biophysical techniques, which were also employed to study chemical unfolding and stability. Divalent metal ions caused significant acceleration to the rate of SEPT4-G aggregation. Urea induced unfolding was shown to proceed via the formation of a partially unfolded intermediate state which unfolds further at higher urea concentrations. The intermediate is a compact dimer which is unable to bind GTR At 1 M urea concentration, the intermediate state was plagued by irreversible aggregation at temperatures above 30 degrees C. However, higher urea concentration resulted in a marked decay of the aggregation, indicating that the partially folded structures may be necessary for the formation of these aggregates. The results presented here are consistent with the recently determined crystal structure of human septins and shed light on the aggregation properties of SEPT4 pertinent to its involvement in neurodegenerative disease.

Automatic contour extraction from 2D neuron images

This work describes a novel methodology for automatic contour extraction from 2D images of 3D neurons (e.g. camera lucida images and other types of 2D microscopy). Most contour-based shape analysis methods cannot be used to characterize such cells because of overlaps between neuronal processes. The proposed framework is specifically aimed at the problem of contour following even in presence of multiple overlaps. First, the input image is preprocessed in order to obtain an 8-connected skeleton with one-pixel-wide branches, as well as a set of critical regions (i.e., bifurcations and crossings). Next, for each subtree, the tracking stage iteratively labels all valid pixel of branches, tip to a critical region, where it determines the suitable direction to proceed. Finally, the labeled skeleton segments are followed in order to yield the parametric contour of the neuronal shape under analysis. The reported system was successfully tested with respect to several images and the results from a set of three neuron images are presented here, each pertaining to a different class, i.e. alpha, delta and epsilon ganglion cells, containing a total of 34 crossings. The algorithms successfully got across all these overlaps. The method has also been found to exhibit robustness even for images with close parallel segments. The proposed method is robust and may be implemented in an efficient manner. The introduction of this approach should pave the way for more systematic application of contour-based shape analysis methods in neuronal morphology. (C) 2008 Elsevier B.V. All rights reserved.

Gas-Phase Acylium Ion Transfer Reactions Mediated by a Proton Shuttle Mechanism

The mechanism and the energy profile of the gas-phase reaction that mimics esterification under acidic conditions have been investigated at different levels of theory. These reactions are known to proceed with rate constants close to the collision limit in the gas-phase and questions have been raised as to whether the typical addition-elimination mechanism via a tetrahedral intermediate can explain the ease of these processes. Because these reactions are common to many organic and biochemical processes it is important to understand the intrinsic reactivity of these systems. Our calculations at different levels of theory reveal that a stepwise mechanism via a tetrahedral species is characterized by energy barriers that are inconsistent with the experimental results. For the thermoneutral exchange between protonated acetic acid and water and the exothermic reaction of protonated acetic acid and methanol our calculations show that these reactions proceed initially by a proton shuttle between the carbonyl oxygen and the hydroxy oxygen of acetic acid mediated by water, or methanol, followed by displacement at the acylium ion center. These findings suggest that the reactions in the gas-phase should be viewed as an acylium ion transfer reaction. (C) 2010 Wiley Periodicals, Inc. Int J Quantum Chem 111: 1596-1606, 2011

Myth and Society: Functions, Uses, and Abuses of Myth in Society

In this work, I will discuss the integral role that myth has in society and then, after presenting several examples of this thesis, I will examine how the integral nature of myth lends itself to certain societal abuses. These abuses often result in unjust social constructs that eventually become attributed to the myth. I would like to proceed in defense of myth; that is, that these constructs are not to be attributed to the myths themselves, rather, society has taken myth and applied it to suit its purposes, ignoring the context in which the myths originated. Hopefully this will raise society's current attitudes toward myth to a level of respect, and will also help to clear myth of its reputation as the origin of injustice and domination.

Modelagem dos tempos de falhas ao longo do calendário

Um dos modos de avaliar a confiabilidade de um produto é verificando o comportamento das falhas em testes de uso contínuo. Contudo, essa informação não permite saber em que data a falha ocorrerá. Para resolver esse impasse abordamos na presente dissertação a modelagem dos tempos de falha ao longo do calendário. A modelagem desses tempos permite uma melhor administração do sistema de garantia e assistência técnica, além de possibilitar a empresa estimar e monitorar a confiabilidade do produto. Para proceder com a modelagem, é preciso, inicialmente, conhecer a distribuição de três variáveis: o tempo de vida do produto, em horas de uso contínuo; o tempo de uso do produto, em horas por dia; e o intervalo de tempo entre a manufatura e a venda, em dias. Conhecendo o comportamento dessa variáveis duas alternativas de solução são apresentadas: (a) Modelagem via simulação de Monte Carlo e (b) Modelagem através de solução matemática fechada. São discutidos os casos em que há um ou vários grupos de clientes que utilizam o produto.

Como o marketing verde interfere na imagem da marca da indústria de celulose: o estudo de caso da aracruz celulose

The purpose of this work, is to analyze the principles underlying the pulp and paper industry, here portrayed by Aracruz Celulose S A, in the marketing standpoint, as far as it concerns being in harmony with nature and adapting its relations with the stakeholders, notably regarding the community of the State of Espírito Santo. As they form, indeed, part of the same discussion, the goal is to proceed with a detailed examination of the major aspects and conditions involved, based in its corporate communications, leading to the construction of a positive corporate brand. The results found throughout this study show that despite Aracruz and the communities¿ different goals, they converge regarding their interests towards the best practices in social and environmental practices, and a more objective communication. Industry and community can work together for a same benefit: the best relations of man towards Nature, and of man towards man. The examples here stated will endorse our perception as well as serve to evaluate the results of the measures adopted in this relationship. It could be verified how internal and external aspects of the organization influence the company¿s reputation, leading to important changes in attitude and in the production process. Pressures from stakeholders have contributed largely in helping Aracruz become more conscious of the important role it plays in the social-environmental universe of the State of Espírito Santo. The assessment of leading the process of communications within in-depth transparency have signaled that, despite a closer approach with its stakeholders, Aracruz still needs to fulfill an existing gap: an excellent rapport between the company and the communities where it influences still needs to be pursued, especially regarding communicating its activities.

Políticas públicas para radiodifusão e imprensa: ação e omissão do estado no Brasil pós-1964

The press and the State had developed, in Brazil, a relation of interdependence. Press and broadcasting corporations depend on state money for its survival and politicians depend on the press and the exposition in the media to communicate with their electorate. This relation of proximity affects the elaboration of public policies for the sector. This study analyzes public policies for broadcasting and the press since 1964, when it was established in the country the military regimen, a mark of a deep reform in the Communications. Public policies are debated in line with two dimensions - one relative to the infrastructure needed by the Communications, and another referring to the content of information. Our conclusion clarifies the urgency of a revision in the laws that regulate the media, many of which are not applicable anymore, and questions the independence of Brazilian parliamentarians to proceed with the necessary reforms and to the discussion about new public policies for the sector.

Privatização da Vale do Rio Doce: valores, manifestações e implicações

Este estudo investigou, na Companhia Vale do Rio Doce (CVRD), como os funcionários perceberam as mudanças ocorridas na empresa, as ações da alta administração e o que ocorreu com os valores na organização após o processo de privatização. O objetivo final da pesquisa foi verificar que valores norteiam as propostas administrativas da Vale após a privatização, e como se manifestam nas ações e na postura dos agentes na sede da empresa. O referencial teórico incluiu mudança organizacional, teoria dos valores e responsabilidade das ações administrativas, para compreender o contexto atual da empresa após a privatização. A pesquisa de campo foi concebida sob o paradigma do construtivismo, em busca de percepções e sentimentos subjacentes e manifestos em entrevistas e questionários a fim de explicitar os valores passados e presentes na organização e possibilidades de uma nova realidade. Uma abordagem fenomenológica complementar favoreceu a inserção da autora no mundo da vida dessa organização, facilitando a fluência do diálogo para a apreensão de manifestações e implicações dos valores das pessoas no processo de transição. As reflexões finais indicam a necessidade de um trabalho organizacional que envolva funcionários e alta administração com o propósito comum de redescoberta do significado próprio da organização. O Programa Vale Viver surge como uma tentativa nessa direção. Os valores "vestir a camisa", "valorizar a prata da casa" e "vencer desafios" acompanham o tempo de vida da cultura da Vale. O valor "vestir a camisa," cujo significado é compartilhamento autêntico, na atualidade é mais uma expectativa a ser retomada do que uma vivência. O valor "vencer desafios" está mais presente na área operacional e o valor "valorizar a prata da casa" aparece mais relacionado a programas como o Banco de OpOliunidades, reavivado pelo Vale Viver. Não significa que o Vale Viver seja a única saída para a retomada da confiança, da elevação da auto-estima e de uma articulação empregados e nova administração na construção de uma base comum de valores, mas é a possibilidade mais visível no momento em que a retomada do espírito da V ALE é fundamental para essa nova etapa de sua vida.

Auditoria operacional aplicada a sistemas municipais de saúde: um estudo a partir da experiência do Tribunal de Contas do Estado do Rio de Janeiro

This research aimed at evaluating the efficiency of a specific model of operational auditing, created to audit municipal health systems, which are part of the Sistema Único de Saúde in the State of Rio de Janeiro, the AOSMS. Thus, it attempted to find out whether they represent a valid method of auditing the performance of SUS in the State of Rio de Janeiro based on the isolated or combined utilization of efficiency and efficacy criteria, and to finalize, how the AOSMS may contribute to the improvement of the municipal management of SUS. The study is based on two references axes, as follows: criteria and paradigms of operational auditing according to what International Organization of Supreme Audit Institutions (INTOSAI) understands about this methodology and the evaluation method of health services proposed by Avedis Donabedian, based on the triad structure, process and result. The work consisted initially in verifying compatibility and evaluating potential of the parameters that constitute the AOSMS with the adopted references, in the light of the basic principles that inform the Brazilian Sistema Único de Saúde and afterwards in the submission of these parameters to the analytic categories created in this study with the intent of checking its adequacy and pertinacity to analyze public health systems. In order to reach its objective the research used the case study strategy of the TCE-RJ experience of holding operational audit in 39 municipal health systems in the State of Rio de Janeiro developed between 2000 and 2007. The result confirmed the hypothesis of the study and revealed how the AOSMS, considered as a valid methodology for its finality, may contribute for the improvement of the municipal management of SUS, reaffirming the potential of operational auditing to proceed with the evaluation of the performance of the Sistema Único de Saúde in the angle of external control, considering however that its application in Brazil, because of the external control model constitutionally adopted, must pass through due sociological reduction2.

Princípio republicano, cargo em comissão e clientelismo político nos municípios do estado do Rio de Janeiro: reflexões sobre a profissionalização da função pública no Brasil

A origem do comportamento orientado para a conquista de cargos públicos no Brasil remonta à formação dos primeiros povoados e vilas durante o período colonial. O nepotismo e o clientelismo político perpassam toda a história do País. Tendo como fio condutor o princípio republicano, buscou-se verificar até que ponto são os cargos em comissão utilizados no âmbito dos Municípios do Estado do Rio de Janeiro como estratégia para manter e atualizar práticas clientelísticas como o empreguismo e o nepotismo. A utilização de métodos e técnicas de análise documental e de conteúdo, em dispositivos legais produzidos pelos municípios estudados e em Relatórios de Inspeções Ordinárias neles realizadas pelo Tribunal de Contas do Estado do Rio de Janeiro, permitiu não só o proceder de uma análise qualitativa como o uso de técnicas quantitativas e representações gráficas dos achados, possibilitando uma leitura mais amena àqueles que têm pouco contato com a matéria. Essa complementaridade de métodos permitiu depreender que as ações empreendidas pelos gestores públicos, no que tange à utilização da livre nomeação, encontram-se na contramão da prática da cidadania, do igualitarismo, do respeito ao servir público. A pesquisa atestou que a quase totalidade dos municípios estudados se utiliza dos cargos em comissão de forma totalmente avessa à prevista constitucionalmente, servindo tais cargos, na verdade, para dar ingresso no serviço público a pessoas das relações do administrador, não para assessorá-lo, mas para aumentar renda familiar, cumprir compromissos de campanha e, até mesmo, para, em troca de votos, exercerem funções que por suas características deveriam ser oferecidas em concurso a toda sociedade. O estudo sugere, ao fim, um conjunto de medidas, baseadas em critérios fundamentados em princípios científicos de gestão, visando à valorização do servidor público, à redução do grau de politização da direção da administração pública e da apropriação patrimonialista dos postos de trabalho, à aceleração da profissionalização das funções públicas e a restringir o livre provimento de cargos em comissão, bem como a impingir sanções, por improbidade administrativa, aos que as desrespeitarem. Em que pese à importância de medidas preventivas, orientadas para o desenvolvimento de uma postura no sentido de um autêntico servir público, a tendência à permissividade precisa ser urgentemente afastada.

É necessário o conhecimento básico da organização, o contexto em que a mesma se enquadra, e de que forma deveremos atuar em seu desenvolvimento Para esta adota-se etapas onde analisamos o empreendimento, políticas ou diretrizes organizacionais, a metodologia de implantação sistemicas, associada às reais necessidades da empresa, bem como sua infraestrutura e capacidade de esforço

O poder legislativo na verificação da legitimidade constitucional do processo de construção das leis

It is known that, in the Democratic State of Law paradigm, one of the most instigating themes is the legitimity of the Law. It justifies the interest in reflecting about the Legislative Process instituted by the Brasilian 1988 Constitution, more specifically field of the constitutionality control as away to guaranty of the legitimity of the Law. The research that is developed here, intents to bring to reflection the basis and the ways the Legislative Power has to proceed to Constitutionality Control of the laws and of the Legislative Process. As the focus taken here is about the Legislative Power, it starts from the presupposed that only by the adoption of legislative process which has to be connected to a rational speech, that will evidence the Democratic and Procedimental Law dimensions, guarantee the possibility of the public and private spheres of life act in complementarity that is such needed to the stabilization of the social expectatives and the concretization of the Brazilian Constitution

Em busca do conhecimento da equipe de enfermagem na sua prática assistencial às vítimas de traumatismo raquimedular

The great demand of accidents resulting in victims with rachi-medullar traumatism (RMT) and the need for indetifying how they are being assisted, led us to proceed with this investigation. It had as its goal to identify and analyze the knowledge of nurses and nurse assistents regarding the nursing assistance to these patients. It consists of a descriptive exploratory study, with a quantitative method and prospective data. For its execution, 193 subjects were interviewed, 37 of them nurses and 157 nurse assistents in 02 hospitals of the metropolitan zone of Natal. The results reveal that the subjects are not coherent when questioned whether they are prepared to assist victim of RMT and the content described by order of piority regarding the steps followed in the assistance of these victims, both in the pre-hospital and hospital care. Thus, we observe that only 06 nurses and 07 assistents, described correctly all the steps necessary to pre-hospital care and only 01 nurse and 02 assistents registered all the steps in the correct sequence regarding the hospital care. We conclude that, in face of the obtained results, we can urgently modify this reality, improving the nursing staff and giving them better work conditions
