Envelhecimento bem-sucedido : processo de interação enfermeiro-pessoa idosa em cuidados de saúde primários

Com o envelhecimento demográfico e o natural aumento dos cuidados de enfermagem no âmbito gerontológico surge o interesse em responder como é que o enfermeiro interage com a pessoa idosa para que esta utilize a sua essência evidenciando comportamentos protetores e promotores de envelhecimento bem-sucedido? E ao objetivo: compreender o processo da interação enfermeiro-pessoa idosa que conduz à utilização de comportamentos protetores e promotores de envelhecimento bem-sucedido. Trata-se de um estudo naturalista de paradigma qualitativo, de pensamento indutivo, desenvolvido num contexto de cuidados de saúde primários. Observámos o processo de interação entre enfermeiro-pessoa idosa num Agrupamento de Centros de Saúde e em Centros de Dia/Convívio e completámos a informação com entrevista. Utilizámos o método de análise grounded theory segundo Corbin & Strauss[1] que prevê a triangulação de dados bem como o recurso a amostragem teórica. A interação enfermeiro-pessoa idosa estabelece-se num processo conjunto de recriação do cuidado gerontológico predispondo, favorecendo e reforçando o conhecimento sobre o cerne da vida. A pessoa idosa objeto de cuidados do enfermeiro vai construindo o seu vivido caminhando para a integridade, estabelecendo interação individual e social e intensificando vivências. De todo este processo de interação emerge o conceito central: clarificação do vivido.

Algorithm for generating defective graphene sheets

An algorithm is presented for the generation of molecular models of defective graphene fragments, containing a majority of 6-membered rings with a small number of 5- and 7-membered rings as defects. The structures are generated from an initial random array of points in 2D space, which are then subject to Delaunay triangulation. The dual of the triangulation forms a Voronoi tessellation of polygons with a range of ring sizes. An iterative cycle of refinement, involving deletion and addition of points followed by further triangulation, is performed until the user-defined criteria for the number of defects are met. The array of points and connectivities are then converted to a molecular structure and subject to geometry optimization using a standard molecular modeling package to generate final atomic coordinates. On the basis of molecular mechanics with minimization, this automated method can generate structures, which conform to user-supplied criteria and avoid the potential bias associated with the manual building of structures. One application of the algorithm is the generation of structures for the evaluation of the reactivity of different defect sites. Ab initio electronic structure calculations on a representative structure indicate preferential fluorination close to 5-ring defects.

Realistic mean field forward predictions for the integration of co-registered EEG/fMRI

Brain activity can be measured non-invasively with functional imaging techniques. Each pixel in such an image represents a neural mass of about 105 to 107 neurons. Mean field models (MFMs) approximate their activity by averaging out neural variability while retaining salient underlying features, like neurotransmitter kinetics. However, MFMs incorporating the regional variability, realistic geometry and connectivity of cortex have so far appeared intractable. This lack of biological realism has led to a focus on gross temporal features of the EEG. We address these impediments and showcase a "proof of principle" forward prediction of co-registered EEG/fMRI for a full-size human cortex in a realistic head model with anatomical connectivity, see figure 1. MFMs usually assume homogeneous neural masses, isotropic long-range connectivity and simplistic signal expression to allow rapid computation with partial differential equations. But these approximations are insufficient in particular for the high spatial resolution obtained with fMRI, since different cortical areas vary in their architectonic and dynamical properties, have complex connectivity, and can contribute non-trivially to the measured signal. Our code instead supports the local variation of model parameters and freely chosen connectivity for many thousand triangulation nodes spanning a cortical surface extracted from structural MRI. This allows the introduction of realistic anatomical and physiological parameters for cortical areas and their connectivity, including both intra- and inter-area connections. Proper cortical folding and conduction through a realistic head model is then added to obtain accurate signal expression for a comparison to experimental data. To showcase the synergy of these computational developments, we predict simultaneously EEG and fMRI BOLD responses by adding an established model for neurovascular coupling and convolving "Balloon-Windkessel" hemodynamics. We also incorporate regional connectivity extracted from the CoCoMac database [1]. Importantly, these extensions can be easily adapted according to future insights and data. Furthermore, while our own simulation is based on one specific MFM [2], the computational framework is general and can be applied to models favored by the user. Finally, we provide a brief outlook on improving the integration of multi-modal imaging data through iterative fits of a single underlying MFM in this realistic simulation framework.

The roles and competencies of HR managers in Slovenian multinational companies

Purpose – The HRM literature provides various typologies of the HR managers’ roles in organizations. The purpose of this paper is to examine how the roles and required competencies of HR managers in Slovenian multinational companies change when these companies enter the international arena. Design/methodology/approach – The authors explored the total population of 25 Slovenian multinational companies (MNCs) operating in Serbia. In these companies the authors conducted interviews with 16 expatriates working in branches in Serbia, sent questionnaires to the CEOs, and conducted a survey of 50 HR managers and interviews with 15 of them. The authors used a triangulation approach and analyzed the results by multivariate methods and content analysis. Findings – The authors found that the complexity of HR managers’ roles, and expectations of their competencies, increases with an increasing level of internationalization of companies. Orientation to people and conflict resolution are seen as elementary competencies needed in all stages of internationalization. The key competence is seen to be strategic thinking that, according to CEOs and expatriates, goes hand in hand with cultural sensitivity, openness to change and a comprehensive understanding of the international environment and business processes. Practical implications – These results can potentially be used for assessing the HRM roles and competencies in different stages of company internationalization, especially MNCs operating in the ex-communist states of Europe, and will help HR managers to support expatriates, CEOs and other employees working in branches abroad more efficiently. Originality/value – This study contributes to the review and evaluation of the quite limited research on HR managers’ roles and competencies in MNCs. It focuses on MNCs and outward internationalization in the Central and Eastern European region. It contributes to studies of the HR managers’ roles and competencies and is the first study to establish a set of roles and competencies for HR managers in Slovenian MNCs.

Typographic layout and first impressions: testing how changes in text layout influence reader's judgments of documents

This study explores how the typographic layout of information influences readers' impressions of magazine contents pages. Thirteen descriptors were used in a paired comparison procedure that assessed whether participants' rhetorical impressions of a set of six controlled documents change in relation to variations in layout. The combinations of layout attributes tested were derived from the structural attributes associated with three patterns of typographic differentiation (high, moderate, and low) described in a previous study (see Moys, 2014). The content and the range of stylistic attributes applied to the test material were controlled in order to focus on layout attributes. Triangulation of the quantitative and qualitative data indicates that, even within the experimental confines of limited stylistic differentiation, the layout attributes associated with patterns of high, moderate, and low typographic differentiation do influence readers' rhetorical judgments. In addition, the findings emphasize the importance of considering inter-relationships between clusters of typographic attributes rather than testing isolated variables.

Researching farmer behaviour in climate change adaptation and sustainable agriculture: lessons learned from five case studies

Understanding farmer behaviour is needed for local agricultural systems to produce food sustainably while facing multiple pressures. We synthesize existing literature to identify three fundamental questions that correspond to three distinct areas of knowledge necessary to understand farmer behaviour: 1) decision-making model; 2) cross-scale and cross-level pressures; and 3) temporal dynamics. We use this framework to compare five interdisciplinary case studies of agricultural systems in distinct geographical contexts across the globe. We find that these three areas of knowledge are important to understanding farmer behaviour, and can be used to guide the interdisciplinary design and interpretation of studies in the future. Most importantly, we find that these three areas need to be addressed simultaneously in order to understand farmer behaviour. We also identify three methodological challenges hindering this understanding: the suitability of theoretical frameworks, the trade-offs among methods and the limited timeframe of typical research projects. We propose that a triangulation research strategy that makes use of mixed methods, or collaborations between researchers across mixed disciplines, can be used to successfully address all three areas simultaneously and show how this has been achieved in the case studies. The framework facilitates interdisciplinary research on farmer behaviour by opening up spaces of structured dialogue on assumptions, research questions and methods employed in investigation.

'Rules of engagement’: how experiential learning facilitates the formation of a public–private partnership in Russia

Purpose – The purpose of this paper is to investigate to what extent one can apply experiential learning theory (ELT) to the public-private partnership (PPP) setting in Russia and to draw insights regarding the learning cycle ' s nature. Additionally, the paper assesses whether the PPP case confirms Kolb ' s ELT. Design/methodology/approach – The case study draws upon primary data which the authors collected by interviewing informants including a PPP operator ' s managers, lawyers from Russian law firms and an expert from the National PPP Centre. The authors accomplished data source triangulation in order to ensure a high degree of research validity. Findings – Experiential learning has resulted in a successful and a relatively fast PPP project launch without the concessionary framework. The lessons learned include the need for effective stakeholder engagement; avoiding being stuck in bureaucracy such as collaboration with Federal Ministries and anti-trust agency; avoiding application for government funding as the approval process is tangled and lengthy; attracting strategic private investors; shaping positive public perception of a PPP project; and making continuous efforts in order to effectively mitigate the public acceptance risk. Originality/value – The paper contributes to ELT by incorporating the impact of social environment in the learning model. Additionally, the paper tests the applicability of ELT to learning in the complex organisational setting, i.e., a PPP.

Twofold adaptive partition of unity implicits

Partition of Unity Implicits (PUI) has been recently introduced for surface reconstruction from point clouds. In this work, we propose a PUI method that employs a set of well-observed solutions in order to produce geometrically pleasant results without requiring time consuming or mathematically overloaded computations. One feature of our technique is the use of multivariate orthogonal polynomials in the least-squares approximation, which allows the recursive refinement of the local fittings in terms of the degree of the polynomial. However, since the use of high-order approximations based only on the number of available points is not reliable, we introduce the concept of coverage domain. In addition, the method relies on the use of an algebraically defined triangulation to handle two important tasks in PUI: the spatial decomposition and an adaptive polygonization. As the spatial subdivision is based on tetrahedra, the generated mesh may present poorly-shaped triangles that are improved in this work by means a specific vertex displacement technique. Furthermore, we also address sharp features and raw data treatment. A further contribution is based on the PUI locality property that leads to an intuitive scheme for improving or repairing the surface by means of editing local functions.

Front tracking with moving-least-squares surfaces

The representation of interfaces by means of the algebraic moving-least-squares (AMLS) technique is addressed. This technique, in which the interface is represented by an unconnected set of points, is interesting for evolving fluid interfaces since there is]to surface connectivity. The position of the surface points can thus be updated without concerns about the quality of any surface triangulation. We introduce a novel AMLS technique especially designed for evolving-interfaces applications that we denote RAMLS (for Robust AMLS). The main advantages with respect to previous AMLS techniques are: increased robustness, computational efficiency, and being free of user-tuned parameters. Further, we propose a new front-tracking method based on the Lagrangian advection of the unconnected point set that defines the RAMLS surface. We assume that a background Eulerian grid is defined with some grid spacing h. The advection of the point set makes the surface evolve in time. The point cloud can be regenerated at any time (in particular, we regenerate it each time step) by intersecting the gridlines with the evolved surface, which guarantees that the density of points on the surface is always well balanced. The intersection algorithm is essentially a ray-tracing algorithm, well-studied in computer graphics, in which a line (ray) is traced so as to detect all intersections with a surface. Also, the tracing of each gridline is independent and can thus be performed in parallel. Several tests are reported assessing first the accuracy of the proposed RAMLS technique, and then of the front-tracking method based on it. Comparison with previous Eulerian, Lagrangian and hybrid techniques encourage further development of the proposed method for fluid mechanics applications. (C) 2008 Elsevier Inc. All rights reserved.

Generating segmented meshes from textured color images

This paper presents a new framework for generating triangular meshes from textured color images. The proposed framework combines a texture classification technique, called W-operator, with Imesh, a method originally conceived to generate simplicial meshes from gray scale images. An extension of W-operators to handle textured color images is proposed, which employs a combination of RGB and HSV channels and Sequential Floating Forward Search guided by mean conditional entropy criterion to extract features from the training data. The W-operator is built into the local error estimation used by Imesh to choose the mesh vertices. Furthermore, the W-operator also enables to assign a label to the triangles during the mesh construction, thus allowing to obtain a segmented mesh at the end of the process. The presented results show that the combination of W-operators with Imesh gives rise to a texture classification-based triangle mesh generation framework that outperforms pixel based methods.

En studie om rehabilitering - en skamgörande process

The purpose of this essay is using theories about labeling and social bonds to study whether a measure of rehabilitation for the psychically disabled contributes to a return to a normal status as not-labeled. Partly we examine whether the activities organized by the regulation-ruled authorities during the work of rehabilitation lead to shame or pride, and partly how these activities are organized regarding the processes that lead to the emotions pride or shame among the participants. Method: qualitative semi-structured face-to-face interviews with professional rehabilitation-actors at the Public Employment Office (PEO), the Social Insurance Office (SIO), the Social Service (SOS), the Psychiatry and the Division of Labour Market (AME).Conclusions: the Psychiatry clients are treated with respect, may participate, and communication is characterized by attunement, therefore strong social bonds can be built. On the contrary, among the other examined activities, we found many elements that arouse shame. Since these are more ruled by regulations, the result is engulfment and demands on conformity, because the compromise-possibilities are almost non-existent. Psychically disabled persons are met by prejudice, ignorance, disrespect and a non-solidarity-language. To get help, the individual has to accept a label in form of a diagnosis, and this labeling leads to a negative self-image. Furthermore the psychically disabled persons are falling between two chairs because of a weak cooperation between the rehabilitation-actors. Bimodal alienation and triangulation contributes to the difficulties in cooperation.Result: the social bonds are not strong enough to achieve a rehabilitation-effect. Even if the treatment from each administrator is important, we find the explanation-level primarily in laws, rules and government, because the structure rules the rehabilitation-measures, with shame as a consequence. Since we found elements of shame institutionalized in the way of working at PEO, SIO, SOS and AME, it means that social bonds can never reach a level good enough for achieving pride and normalization from a deviance or labeled identity.

Patient participation : what it is and what it is not

In general, patient participation is regarded as being informed and partaking in decision making regarding one’s care and treatment. This interpretation is common in legislation throughout the Western world and corresponding documents guiding health care professionals, as well as in scientific studies. Even though this understanding of the word participation can be traced to a growing emphasis on individuals’ autonomy in society and to certain dictionary defi nitions, there are other ways of understanding participation from a semantic point of view, and no trace of patients’ descriptions of what it is to participate can be found in these definitions. Hence, the aim of this dissertation was to understand patients’ experience of the phenomenon of patient participation. An additional aim was to understand patients’ experience of non-participation and to describe the conditions for patient participation and non-participation, in order to understand the prerequisites for patient participation. The dissertation comprises four papers. The philosophical ideas of Ricoeur provided a basis for the studies: how communication can present ways to understand and explain experiences of phenomena through phenomenological hermeneutics. The first and second studies involved a group of patients living with chronic heart failure. For the fi rst study, 10 patients were interviewed, with a narrative approach, about their experience of participation and non-participation, as defi ned by the participants. For the second study, 11 visits by three patients at a nurse-led outpatient clinic were observed, and consecutive interviews were performed with the patients and the nurses, investigating what they experience as patient participation and non-participation. A triangulation of data was performed to analyse the occurrence of the phenomena in the observed visits. For paper 3 and 4, a questionnaire was developed and distributed among a diverse group of people who had recent experience of being patients. The questionnaire comprised respondent’s description of what patient participation is, using items based on findings in Study 1, along with open-ended questions for additional aspects and general issues regarding situations in which the respondent had experienced patient participation and/or non-participation. The findings show additional aspects to patient participation: patient participation is being provided with information and knowledge in order for one to comprehend one’s body, disease, and treatment and to be able to take self-care actions based on the context and one’s values. Participation was also found to include providing the information and knowledge one has about the experience of illness and symptoms and of one’s situation. Participation occurs when being listened to and being recognised as an individual and a partner in the health care team. Non-participation, on the other hand, occurs when one is regarded as a symptom, a problem to be solved. To avoid non-participation, the information provided needs to be based on the individual’s need and with recognition of the patient’s knowledge and context. In conclusion, patient participation needs to be reconsidered in health care regulations and in clinical settings: patients’ defi nitions of participation, found to be close to the dictionaries’ description of sharing, should be recognised and opportunities provided for sharing knowledge and experience in two-way-communication.

The Aiyagari model with liquidity shoch

Neste trabalho é desenvolvida uma versão do modelo de Aiyagari (1994) com choque de liquidez. Este modelo tem Huggett (1993) e Aiyagari (1994) como casos particulares, mas esta generalização permite dois ativos distintos na economia, um líquido e outro ilíquido. Usar dois ativos diferentes implica em dois retornos afetando o "market clearing", logo, a estratégia computacional usada por Aiyagari e Hugget não funciona. Consequentemente, a triangulação de Scarf substitui o algoritmo. Este experimento computacional mostra que o retorno em equilíbrio do ativo líquido é menor do que o retorno do ilíquido. Além disso, pessoas pobres carregam relativamente mais o ativo líquido, e essa desigualdade não aparece no modelo de Aiyagari.

Competências e habilidades relevantes para um chefe de unidade descentralizada de perícia da Polícia Federal

Esta pesquisa teve por objetivo apreender e analisar o perfil profissional dos que exercem funções de Chefia nas Unidades descentralizadas de Criminalística da Polícia Federal no Brasil, especificamente nos Setores Técnico-Científicos (SETECs) e nas Unidades Técnico-Científicas (UTECs), segundo a teoria de competências e habilidades. A releitura desses fundamentos, incluindo habilidades sociais nesse escopo, fortaleceu o embasamento teórico para análise dos resultados da etapa empírica desta dissertação. Essa postura, pode contribuir, na prática, para a construção de uma política de gestão de pessoas, baseada em competências, alinhada com o planejamento estratégico em desenvolvimento na organização, otimizando a designação para os cargos de liderança, sobretudo na área de Criminalística com suas especificidades. Além disso, as opções metodológicas qualitativas levaram a perceber tanto lacunas referentes às potencialidades de atuação dos profissionais sujeitos do estudo, quanto competências relevantes e presentes no perfil dos mesmos. Os resultados, ainda, favoreceram clarificar algumas competências técnicas e habilidades como sendo mais relevantes do que outras, diante das exigências peculiares ao exercício da função de Chefe do Setor de Perícia. A articulação das pesquisas bibliográfica, documental, de campo e o procedimento de triangulação de dados de entrevistas, análise documental, observação e aplicação de questionário - por meio do qual foi levantada a percepção dos sujeitos sobre suas funções – possibilitaram conclusões relevantes. Na teoria, ocorreu devido à melhor compreensão das relações entre competências e habilidades e, na prática, por esclarecer o panorama de avanços e limitações na gestão estudada. Conclui-se, pois que o Governo Federal promoveu avanços na política de recursos humanos do Serviço Público, no entanto, a implementação de um sistema moderno de gestão de pessoas ainda não foi consolidado, no Departamento de Polícia Federal. Isso fica evidenciado pela carência de competências primordiais para que os Chefes exerçam com excelência a função de gestores de Unidades de Perícia Técnica.
