An experimental and finite element poroelastic creep response analysis of an intervertebral hydrogel disc model in axial compression

A hydrogel intervertebral disc (lVD) model consisting of an inner nucleus core and an outer anulus ring was manufactured from 30 and 35% by weight Poly(vinyl alcohol) hydrogel (PVA-H) concentrations and subjected to axial compression in between saturated porous endplates at 200 N for 11 h, 30 min. Repeat experiments (n = 4) on different samples (N = 2) show good reproducibility of fluid loss and axial deformation. An axisymmetric nonlinear poroelastic finite element model with variable permeability was developed using commercial finite element software to compare axial deformation and predicted fluid loss with experimental data. The FE predictions indicate differential fluid loss similar to that of biological IVDs, with the nucleus losing more water than the anulus, and there is overall good agreement between experimental and finite element predicted fluid loss. The stress distribution pattern indicates important similarities with the biological lVD that includes stress transference from the nucleus to the anulus upon sustained loading and renders it suitable as a model that can be used in future studies to better understand the role of fluid and stress in biological IVDs.

O ENVELHECIMENTO, A TRANSFERÊNCIA DO CONHECIMENTO E AS RELAÇÕES INTERGERACIONAIS: UM ESTUDO EM EMPRESAS METALÚRGICAS DO ABC PAULISTA

Este estudo busca investigar e compreender o fenômeno do envelhecimento da população no Brasil e também como as organizações estão se preparando para o envelhecimento da sua força de trabalho e para a gestão e transferência do conhecimento acumulado por seus colaboradores. A questão que norteia este estudo é: a transferência do conhecimento acontece entre as gerações antes da saída de pessoas para a aposentadoria? Para responder a estas questões, os referenciais foram os estudos de Ferrigno (2006), Davenport e Prusak (2003) e Takeuchi e Nonaka (2008) que apresentam categorias norteadoras para esta pesquisa, delimitada em duas empresas metalúrgicas no ABC Paulista e no Sindicato da categoria. A metodologia utilizada neste estudo foi qualitativa, com pesquisa exploratório-descritiva, por meio da aplicação de entrevista semiestruturada. De acordo com a pesquisa realizada constatou-se que as organizações compreendem a importância de lidarem com o processo de envelhecimento da força de trabalho em seu contexto organizacional e que é preciso estabelecer práticas para disseminação do conhecimento gerado por seu principal ativo (seu colaborador com maior idade) e promover a relação de aprendizagem intergeracional e a transferência do conhecimento acumulado.

O BÔNUS PROFESSOR

Esta dissertação de mestrado fundamenta-se na pesquisa qualitativa e tem como objetivo a análise da ideologia do Bônus Mérito, instituído para os servidores públicos do Estado de São Paulo no início da década de 2000. Limitamos nossa análise à docência do ensino fundamental. As transformações econômicas, ocorridas a partir da década de 1980 nos países altamente industrializados, passam a exigir a melhoria do ensino dos países emergentes. Em conseqüência, a educação volta a ser revalorizada e a ter papel de destaque para os investimentos externos, através das agências e órgãos internacionais tais como: Bird, Unesco, Banco Mundial, PNUD. A ideologia do Bônus Mérito é um exemplo típico de transferência para o âmbito educacional de modelos de gestão das empresas privadas. Esta ideologia afeta a atividade docente, cujo desempenho é, doravante medido através de pontos, divisão de trabalho, impessoalidade, requalificação profissional etc. Efetivamente, em meio à globalização da economia e ao contexto político neoliberal, o governo do Estado de São Paulo optou, no período analisado, por seguir as determinações das grandes potências econômicas. O repasse de recursos financeiros recebidos pelo Estado para a efetivação das mudanças educacionais (diminuição da evasão, universalização das matrículas, aumento do número de alunos com aprovação) esteve condicionado às exigências das referidas agências e órgãos internacionais. Como é demonstrado neste trabalho, essa política relega a segundo plano o docente e sua prática de ensino. A explicitação do fundamento da ideologia do bônus no interior da escola pública visa demonstrar, em primeiro lugar, que o Bônus Mérito é um aparente benefício ao docente; e, em segundo lugar, que sua implantação não é outra coisa que o domínio econômico sobre o projeto educacional.

MANEJO TÉCNICO DO ATENDIMENTO PSICOLÓGICO EM AMBULATÓRIO DE REPRODUÇÃO HUMANA ASSISTIDA

O presente estudo teve por objetivos: descrever o manejo técnico do atendimento psicológico, ilustrado pelo caso de uma paciente infértil de um ambulatório de reprodução humana assistida; descrever as vicissitudes no campo analítico nestes atendimentos; e sistematizar esse manejo técnico em intervenções ambulatoriais em que se privilegia a compreensão das relações transferenciais. O instrumento utilizado para a coleta de dados foram os próprios atendimentos, ou entrevistas psicológicas, baseadas no método clínico de abordagem psicanalítica. A análise e a discussão dos resultados se basearam na apresentação de um único caso, que ilustrou a técnica que se objetivou sistematizar e descrever. É apresentado o caso da Sra. S., uma mulher de 41 anos, com parceiro em união estável há cinco anos, que realizava tratamento de infertilidade no ambulatório de reprodução humana. A paciente foi atendida pela psicóloga no próprio ambulatório durante o período da segunda tentativa de gravidez. Foram realizados efetivamente três (3) atendimentos e, no período de dois meses, a paciente não compareceu a três (3) sessões. Foram criadas cinco (5) categorias de análise: 1) Escuta; 2) Configuração de Queixa Psicológica; 3) Manejo dos Conflitos; 4) Manejo da Transferência; e 5) Enquadre. Estas categorias representaram elementos do atendimento. A divisão do atendimento em categorias teve propósito didático, no entanto, a sistematização do manejo deu-se a partir do desenvolvimento destas categorias, mas não numa ordem pré-estabelecida. A Escuta refere-se à capacidade do psicoterapeuta compreender a relação estabelecida com o paciente, assim como os elementos metapsicológicos depositados no campo, a partir de seu quadro de referência teórico-metodológico. A Configuração de Queixa Psicológica refere-se à aproximação do sofrimento psíquico e dos conflitos que subjazem à queixa orgânica ou manifesta. O Manejo dos Conflitos representa o modo como são interpretados e devolvidos a um paciente os conteúdos trazidos para a sessão. Ressalta-se, no manejo dos conflitos, a eleição de um foco de trabalho em que se privilegia a situação atual da vida do paciente relacionada especificamente à sua queixa. O Manejo da Transferência refere-se à forma como os aspectos transferenciais são compreendidos e devolvidos ao paciente. A neurose e psicose de transferência são evitadas e o trabalho é preferencialmente desenvolvido a partir da interpretação de situações extra-transferenciais. Por fim, o Enquadre engloba todos os aspectos formais e dinâmicos que constituem o campo emocional sobre o qual se trabalha. Este tipo de atendimento pode ser situado entre a entrevista psicológica e o atendimento em psicoterapia breve com objetivos e tempo limitados, variando de acordo com a qualidade adaptativa do paciente e sua motivação para o atendimento psicológico. Concluímos que este modelo de atendimento ambulatorial engloba aspectos tanto diagnósticos quanto de intervenção e que o papel do psicólogo neste contexto é auxiliar o paciente atendido a compreender sua queixa em seus aspectos latentes e manifestos, além de propiciar um espaço de escuta em que os conteúdos trazidos podem ser pensados e compreendidos

The significance of hand wash compliance on the transfer of dermal lipids in contact lens wear

Aim: The aim of this study was to assess the impact of hand washing regimes on lipid transference to contact lenses. The presence of lipids on contact lenses can affect visual acuity and enhance spoilation. Additionally, they may even mediate and foster microbial transfer and serve as a marker of potential dermal contamination. Methods and materials: A social hand wash and the Royal College of Nursing (RCN) hand wash were investigated. A 'no-wash regime' was used as control. The transfer of lipids from the hand was assessed by Thin Layer Chromatography (TLC). Lipid transference to the contact lenses was studied through fluorescence spectroscopy (FS). Results: Iodine staining, for presence of lipids, on TLC plates indicated the 'no-wash regime' score averaged at 3.4 ± 0.8, the social wash averaged at 2.2 ± 0.9 and the RCN averaged at 1.2 ± 0.3 on a scale of 1-4. The FS of lipids on contact lenses for 'no washing' presented an average of 28.47 ± 10.54 fluorescence units (FU), the social wash presented an average of 13.52 ± 11.12. FU and the RCN wash presented a much lower average 6.47 ± 4.26. FU. Conclusions: This work demonstrates how the method used for washing the hands can affect the concentration of lipids, and the transfer of these lipids onto contact lenses. A regime of hand washing for contact lens users should be standardised to help reduce potentially transferable species present on the hands. © 2011 British Contact Lens Association.

Informal boundary-spanning links and networks in successful technological innovation

The sources of ideas embodied within successful technological innovation has been a subject of interest in many studies since the 1950s. This research suggests that sources external to the innovating organisation account for between one and two-thirds of the inputs important to the innovation process. In addition, studies have long highlighted the important role played by the personal boundary-spanning relationships of engineers and scientists as a channel for the transference of such inputs. However, research concerning the role and nature of personal boundary-spanning links in the innovation process have either been primarily structurally orientated, seeking to map out the informal networks of scientists and engineers, or more typically, anecdotal. The objective of this research was to reveal and build upon our knowledge of the role, nature and importance of informal exchange activity in the innovation process. In order to achieve this, an empirical study was undertaken to determine the informal sources, channels and mechanisms employed in the development of thirty five award-winning innovations. Through the adoption of the network perspective, the multiple sources and pluralistic patterns of collaboration and communication in the innovation process were systematically explored. This approach provided a framework that allowed for the detailed study of both the individual dyadic links and morphology of the innovation action-sets in which these dyads were embedded. The research found, for example, that the mobilisation of boundary-spanning links and networks was an important or critical factor in nineteen (54%) of the development projects. Of these, informal boundary-spanning exchange activity was considered to be important or critical in eight (23%).

The strength of column-to-foundation joints in reinforced concrete

This thesis is concerned with the experimental and theoretical investigation into the compression bond of column longitudinal reinforcement in the transference of axial load from a reinforced concrete column to a base. Experimental work includes twelve tests with square twisted bars and twenty four tests with ribbed bars. The effects of bar size, anchorage length in the base, plan area of the base, provision of bae tensile reinforcement, links around the column bars in the base, plan area of column and concrete compressive strength were investigated in the tests. The tests indicated that the strength of the compression anchorage of deformed reinforcing steel in the concrete was primarily dependent on the concrete strength and the resistance to bursting, which may be available within the anchorage . It was shown in the tests without concreted columns that due to a large containment over the bars in the foundation, failure occurred due to the breakdown of bond followed by the slip of the column bars along the anchorage length. The experimental work showed that the bar size , the stress in the bar, the anchorage length, provision of the transverse steel and the concrete compressive strength significantly affect the bond stress at failure. The ultimate bond stress decreases as the anchorage length is increased, while the ultimate bond stress increases with increasing each of the remainder parameters. Tests with concreted columns also indicated that a section of the column contributed to the bond length in the foundation by acting as an extra anchorage length. The theoretical work is based on the Mindlin equation( 3), an analytical method used in conjunction with finite difference calculus. The theory is used to plot the distribution of bond stress in the elastic and the elastic-plastic stage of behaviour. The theory is also used to plot the load-vertical displacement relationship of the column bars in the anchorage length, and also to determine the theoretical failure load of foundation. The theoretical solutions are in good agreement with the experimental results and the distribution of bond stress is shown to be significantly influenced by the bar stiffness factor K. A comparison of the experimental results with the current codes shows that the bond stresses currently used are low and in particular, CPIlO(56) specifies very conservative design bond stresses .

State-of-the-art of ‘Lean’ in the aviation maintenance, repair, and overhaul industry

The increasing need for maintenance, repair, and overhaul (MRO) organizations to meet customers' demands in quality and reduced lead times is key to its survival within the aviation industry. Furthermore, with the unpredictability in the global market and difficulties with forecasting characteristic of the MRO industry there is an increased need for the reevaluation of the operation models of organizations within this sector. However, severe economic turmoil and ever-increasing global competition introduce the opportunity for the adoption of a resilient, tried, and tested business operation model such as 'Lean'. In order to understand this concept, its long-term viability, and its application within the aerospace MRO sector fully, this paper presents the state-of-the-art in terms of the adoption of Lean within the MRO industry by carrying out a systematic review of the literature. This paper establishes the common perception of Lean by the MRO industry and the measurable progress that has been made on the subject. Some issues and challenges are also highlighted including the misconceptions that arise from the direct transference of the perception of Lean from other industrial sectors into the aerospace MRO industry. The 'enablers and inhibitors' of Lean within the aviation industry are also discussed. This paper exposes the scarcity of the literature and the general lagging behind of the industry to the adoption of the Lean paradigm and thus highlights areas where further research is required. © 2011 Authors.

Maritime expressions:a corpus based exploration of maritime metaphors

This study uses a purpose-built corpus to explore the linguistic legacy of Britain’s maritime history found in the form of hundreds of specialised ‘Maritime Expressions’ (MEs), such as TAKEN ABACK, ANCHOR and ALOOF, that permeate modern English. Selecting just those expressions commencing with ’A’, it analyses 61 MEs in detail and describes the processes by which these technical expressions, from a highly specialised occupational discourse community, have made their way into modern English. The Maritime Text Corpus (MTC) comprises 8.8 million words, encompassing a range of text types and registers, selected to provide a cross-section of ‘maritime’ writing. It is analysed using WordSmith analytical software (Scott, 2010), with the 100 million-word British National Corpus (BNC) as a reference corpus. Using the MTC, a list of keywords of specific salience within the maritime discourse has been compiled and, using frequency data, concordances and collocations, these MEs are described in detail and their use and form in the MTC and the BNC is compared. The study examines the transformation from ME to figurative use in the general discourse, in terms of form and metaphoricity. MEs are classified according to their metaphorical strength and their transference from maritime usage into new registers and domains such as those of business, politics, sports and reportage etc. A revised model of metaphoricity is developed and a new category of figurative expression, the ‘resonator’, is proposed. Additionally, developing the work of Lakov and Johnson, Kovesces and others on Conceptual Metaphor Theory (CMT), a number of Maritime Conceptual Metaphors are identified and their cultural significance is discussed.

Docência Universitária: o professor agrônomo na construção de sua professoralidade

The aim of this study was to understand how does the teaching learning process of the agronomy professor from Universidade Federal de Uberlândia occurs, analyzing the relationship among training, knowledge and these professors professional identity. The questions which guided the research were: How does the professional identity of these professors are developed in the teaching learning process? Which are the main formation factors that influences this process? Which are the agronomy professors knowledge and how were them built and learned by these professionals in college? This is a research with a qualitative approach, in which most of the data was collected with the professors, through two questionnaires, a simplified and an in-depth one, as well as documents that depict the history of the institute and of the Agronomy department. To guide analysis, we have used, more than the scientific production in the area, the authors Cunha (2008), Tardif (2002), Pimenta (2005), Melo (2009, 2012), Malusá (2005), Pachane (2009), Magalhães (2012), Dubar (2005), Imbernón (2002),Nunez andRamalho (2008), Almeida andPimenta (2012) PimentaandAnastasiou (2002), Cavallet (1999) Pachane (2006), Behrens (2007) Isaia (2008), Malusá (2012) and Nóvoa (1999). The analysis indicated that the teaching learning process of the agronomy professor occurs since college, with the option of been a professor, and throughout their teaching career. Their challenges are related to work conditions, although, the dilemmas between the practices related to the conceptions of traditional and progressive pedagogy can be seen in their class, teaching and teaching learning process conception. Classes are considered by professors as an interaction place but also as a knowledge transference place. This research identifies the necessity of promote cooperation between teachers, so that, the collective and integrated work in formative spaces teachers will have the opportunity to develop the knowledge necessary for teaching. The implementation of institutional initial and continuous formation, through direct dialogue between undergraduate, graduate and training and professional development programs for teachers, with better work conditions will reflect in the constant improvement of training development within universities.

Development of the Oxide Ion Conductor Na0.5Bi0.5TiO3 (NBT) for Solid Oxide Cells

Na0.5Bi0.5TiO3 (NBT) is a well-known lead-free piezoelectric material with potential to replace lead zirconate titanate (PZT),1 however high leakage conductivity for the material has been widely reported.2 Through a combination of Impedance Spectroscopy (IS), O2- ion transference (EMF) number experiments and O18 tracer diffusion measurements, combined with Time-of-flight Secondary Ion Mass Spectrometry (TOFSIMS), it was identified that this leakage conductivity was due to oxygen ion conductivity. The volatilization of bismuth during synthesis, causing oxygen vacancies, is believed to be responsible for the leakage conductivity.3 The oxide-ion conductivity, when doped with magnesium, exceeds that of yttria-stabilized zirconia (YSZ) at ~500 °C,3 making it a potential electrolyte material for Intermediate Temperature Solid Oxide Cells (ITSOCs). Figure 1 shows the comparison of bulk oxide ion conductivity between 2 at.% Mg-doped NBT and other known oxide ion conductors.

As part of the UK wide £5.7m 4CU project, research has concentrated on trying to develop NBT for use in Intermediate Temperature Solid Oxide Cells (ITSOCS). With the aim of achieving mixed ionic and electronic conduction, transition metals were chemically doped on to the Ti-site. A range of experimental techniques was used to characterize the materials aimed at investigating both conductivity and material structure (Scanning Electron Microscopy (SEM), IS, X-ray Photoelectron Spectroscopy (XPS) and X-ray Absorption Spectroscopy (XAS)). The potential for NBT as an ITSOC material, as well as the challenges of developing the material, will be discussed.

Étude exploratoire du recours à des interventions médicales de type "lourd' pour soulager la souffrance existentielle en fin de vie

Au cours du siècle dernier, des améliorations au niveau des conditions de vie ainsi que des avancées importantes dans les sciences biomédicales ont permis de repousser les frontières de la vie. Jusqu’au début du XXe Siècle, la mort était un processus relativement bref, survenant à la suite de maladies infectieuses et avait lieu à la maison. À présent, elle survient plutôt après une longue bataille contre des maladies incurables et des afflictions diverses liées à la vieillesse et a le plus souvent lieu à l’hôpital. Pour comprendre la souffrance du malade d’aujourd’hui et l’aborder, il faut comprendre ce qu’engendre comme ressenti ce nouveau contexte de fin de vie autant pour le patient que pour le clinicien qui en prend soin. Cette thèse se veut ainsi une étude exploratoire et critique des enjeux psychologiques relatifs à cette mort contemporaine avec un intérêt premier pour l’optimisation du soulagement de la souffrance existentielle du patient dans ce contexte. D’abord, je m’intéresserai à la souffrance du patient. À travers un examen critique des écrits, une définition précise et opérationnelle, comportant des critères distinctifs, de ce qu’est la souffrance existentielle en fin de vie sera proposée. Je poserai ainsi l’hypothèse que la souffrance peut être définie comme une forme de construction de l’esprit s’articulant autour de trois concepts : intégrité, altérité et temporalité. D’abord, intégrité au sens où initialement l’individu malade se sent menacé dans sa personne (relation à soi). Ensuite, altérité au sens où la perception de ses conditions extérieures a un impact sur la détresse ressentie (relation à l’Autre). Et finalement, temporalité au sens où l’individu souffrant de façon existentielle semble bien souvent piégé dans un espace-temps particulier (relation au temps). Ensuite, je m’intéresserai à la souffrance du soignant. Dans le contexte d’une condition terminale, il arrive que des interventions lourdes (p. ex. : sédation palliative profonde, interventions invasives) soient discutées et même proposées par un soignant. Je ferai ressortir diverses sources de souffrance propres au soignant et générées par son contact avec le patient (exemples de sources de souffrance : idéal malmené, valeurs personnelles, sentiment d’impuissance, réactions de transfert et de contre-transfert, identification au patient, angoisse de mort). Ensuite, je mettrai en lumière comment ces dites sources de souffrance peuvent constituer des barrières à l’approche de la souffrance du patient, notamment par l’influence possible sur l’approche thérapeutique choisie. On constatera ainsi que la souffrance d’un soignant contribue par moment à mettre en place des mesures visant davantage à l’apaiser lui-même au détriment de son patient. En dernier lieu, j'élaborerai sur la façon dont la rencontre entre un soignant et un patient peut devenir un espace privilégié afin d'aborder la souffrance. J'émettrai certaines suggestions afin d'améliorer les soins de fin de vie par un accompagnement parvenant à mettre la technologie médicale au service de la compassion tout en maintenant la singularité de l'expérience du patient. Pour le soignant, ceci nécessitera une amélioration de sa formation, une prise de conscience de ses propres souffrances et une compréhension de ses limites à soulager l'Autre.

No Joke: Understanding Public Sentiment Toward Selling and Salespeople Through Cartoon Analysis

Unflattering representations of salesmanship in mass media exist in abundance. In order to gauge the depiction of selling in mass media, this article explores the nature and public perceptions of salesmanship using editorial cartoons. A theory of cartooning suggests that editorial cartoons reflect public sentiment toward events and issues and therefore provide a useful way of measuring and tracking such sentiment over time. The criteria of narrative, location, binary struggle, normative transference, and metaphor were used as a framework to analyze 286 cartoons over a 30-year period from 1983 to 2013. The results suggest that while representations of the characteristics and behaviors of salespeople shifted very little across time periods, changes in public perceptions of seller–buyer conflict, the role of the customer, and selling techniques were observed, thus indicating that cartoons are sensitive enough to measure the portrayal of selling.

An Investigation into the Implementation of CYP-IAPT Routine Outcome Measures in their First Year of Integration into Child Psychotherapy Practice

This thesis examines the impact on child and adolescent psychotherapists within CAMHS of the introduction of routine outcome measures (ROMs) associated with the Children and Young People’s Improving access to Psychological Therapies programme (CYP-IAPT). All CAMHS therapists working within a particular NHS mental health Trust1 were required to trial CYP-IAPT ROMs as part of their everyday clinical practice from October 2013-September 2014. During this period considerable freedom was allowed as to which of the measures each therapist used and at what frequency. In order to assess the impact of CYP-IAPT ROMs on child psychotherapy, I conducted semi-structured interviews with eight psychotherapists within a particular CAMHS partnership within one NHS Trust. Each statement was coded and grouped according to whether it related to initial (generic) assessment, goal setting / monitoring, monitoring on-going progress, therapeutic alliance, or to issues concerning how data might be used or interpreted by managers and commissioners. Analysis of interviews revealed greatest concern about session-by session ROMs, as these are felt to impact most significantly on psychotherapy; therapists felt that session-by-session ROMs do not take account of negative transference relationships, they are overly repetitive and used to reward / punish the therapist. Measures used at assessment and review were viewed as most compatible with psychotherapy, although often experienced as excessively time consuming. The Goal Based Outcome Measure was generally experienced as compatible with psychotherapy so long as goals are formed collaboratively between therapist and young person. There was considerable anxiety about how data may be (mis)used and (mis)interpreted by managers and commissioners, for example to end treatment prematurely, trigger change of therapist in the face of negative ROMs data, or to damage psychotherapy. Use of ROMs for short term and generic work was experienced as less intrusive and contentious.
