Análise do trabalho em agentes de contatopaciente: Investigação das táticas utilizadas

A análise do trabalho a que nos propusemos transforma as operações da ação analisada não em instrumento de referência para reproduzilas ou corrigilas, mas sim em instrumento de descoberta de alternativas diversas a partir das quais a ação se constrói. Nesse sentido, o objetivo deste trabalho é verificar as táticas utilizadas pelos agentes de contatopaciente no atendimento de internação em um hospital, no intuito de avaliar o distanciamento entre o trabalho prescrito e o trabalho efetivamente real. Para tanto, utilizouse a entrevista de explicitação como metodologia qualitativa. Também foi analisado o processo de atendimento ao paciente, identificandose tarefas, ações e recursos para obterse melhoria nos resultados com vistas na satisfação do cliente. As táticas específicas de contatocliente foram classificadas em três categorias, baseadas numa tipologia de cliente. A primeira consiste em alterar as demandas que recaem sobre o agente de contatopaciente; a segunda, em tentar impedir os remetentes de dirigir demandas ao agente de contatopaciente; e a terceira em evitar e incluir táticas que permitem ao agente manipular e alterar as demandas recebidas. Nesse sentido, nove táticas foram identificadas.

Assessing the safety of Pseudomonas putida introduction in the environment: an overview of ecotoxicological tests.

Risk assessment guidelines for the environmental release of microbial agents are performed in a tiered sequence which includes evaluation of exposure effects on non target organisms. However, it becomes important to verify whether environmental risk assessment from temperate studies is applicable to tropical countries, as Brazil. Pseudomonas putida is a bacteria showing potential to be used for environmental applications as bioremediation and plant disease control. This study investigates the effects of this bacteria exposure on rodents and aquatic organisms (Daphnia similes) that are recommended to be used as non-target organism in environmental risk assessments. Also, the microbial activity in three different soils under P. putida exposure was evaluated. Rats did not show clinical alterations, although the agent was recovered 16 h after the exposure in lung homogenates. The bacteria did not reduce significantly the reproduction and survival of D. similis. The soil enzymatic activities presented fluctuating values after inoculation with bacteria. The measurement of perturbations in soil biochemical characteristics is presented as an alternative way of monitoring the overall effects of the microbial agent to be introduced even in first stage (Tier I) of the risk assessment in tropical ecosystems.

A tomada de decisão policial nos grandes eventos desportivos

Não sendo possível ao ser humano adivinhar todos os perigos e evitá-los, este, muitas vezes, é confrontado com situações em que tem de dar respostas imediatas, decidir sob a influência de limitações de tempo, stress elevado, conhecimento incompleto, ou pressões sociais, institucionais e políticas. Os limites da mente humana obrigam o decisor a recorrer a estratégias de aproximação para lidar com a maioria das situações, o que resulta, por vezes, em erros e vieses nas avaliações e decisões. O decisor não procura soluções ideais mas sim satisfatórias, suficientes, que lhe permitam responder de forma célere, levando-o, por vezes, a pesquisar pouca informação e a decidir com base num único elemento informativo. Não conseguindo dissociar-se da sua condição humana, o decisor policial sofre das mesmas limitações que o comum cidadão. Realizou-se um estudo qualitativo, em contexto naturalista, sobre a tomada de decisão aplicado à actividade policial em grandes eventos desportivos, no intuito de melhor compreender o processo decisional. Os resultados obtidos revelam que o processo de decisão policial está dependente da capacidade do decisor avaliar os cursos de acção, pesquisar e gerir a informação necessária e antecipar cenários, projectando constantemente expectativas durante o policiamento. Para a realização de tais acções, a experiência e o conhecimento do decisor policial revelam-se factores fundamentais.

Estime de soi et autonomie

Ce mémoire est consacré à la condition de l’estime de soi telle que défendue par Paul Benson au sein de sa théorie substantielle de l’autonomie. Soulevant l’insuffisance des théories procédurales dans les cas d’oppressions, cette condition défend la nécessité de considérer les relations intersubjectives et le sentiment de mérite à agir au sein de la définition même de l’autonomie. En ce sens, les théories relationnelles permettent également de rendre compte de l’impact du contexte social sur les valeurs intériorisées par un agent, mais aussi sur la manière dont un agent s’évalue en fonction de ses expériences. Afin d’approfondir cette condition de l’estime de soi, j’étudie le rôle des émotions autoréflexives sur la perception d’un agent à l’égard de soi tout en soulevant comment ces dernières peuvent l’informer des valeurs qui lui sont propres, de celles provenant d’un contexte d’oppression. Dans un premier temps, j’explore en quoi consiste la condition de l’estime de soi selon Benson, son lien avec l’identité et comment elle met en lumière l’insuffisance des théories procédurales. Dans un deuxième temps, je la distingue des autres conceptions similaires telles que retrouvées dans les théories relationnelles tout en défendant que l’estime de soi n’est pas un phénomène affectif distinct, mais plutôt un jugement normatif s’élaborant à partir des expériences affectives vécues par un agent. Bien que défendant la thèse de Benson dans une perspective relationnelle, j’approfondis la définition de la condition de l’estime de soi en soulevant comment les émotions morales s’avèrent nécessaires pour qu’un agent soit autonome à l’égard de ses actions, de ses pensées et de ses valeurs.

Bionano Electronics: Magneto-Electric Nanoparticles for Drug Delivery, Brain Stimulation and Imaging Applications

Nanoparticles are often considered as efficient drug delivery vehicles for precisely dispensing the therapeutic payloads specifically to the diseased sites in the patient’s body, thereby minimizing the toxic side effects of the payloads on the healthy tissue. However, the fundamental physics that underlies the nanoparticles’ intrinsic interaction with the surrounding cells is inadequately elucidated. The ability of the nanoparticles to precisely control the release of its payloads externally (on-demand) without depending on the physiological conditions of the target sites has the potential to enable patient- and disease-specific nanomedicine, also known as Personalized NanoMedicine (PNM). In this dissertation, magneto-electric nanoparticles (MENs) were utilized for the first time to enable important functions, such as (i) field-controlled high-efficacy dissipation-free targeted drug delivery system and on-demand release at the sub-cellular level, (ii) non-invasive energy-efficient stimulation of deep brain tissue at body temperature, and (iii) a high-sensitivity contrasting agent to map the neuronal activity in the brain non-invasively. First, this dissertation specifically focuses on using MENs as energy-efficient and dissipation-free field-controlled nano-vehicle for targeted delivery and on-demand release of a anti-cancer Paclitaxel (Taxol) drug and a anti-HIV AZT 5’-triphosphate (AZTTP) drug from 30-nm MENs (CoFe2O4-BaTiO3) by applying low-energy DC and low-frequency (below 1000 Hz) AC fields to separate the functions of delivery and release, respectively. Second, this dissertation focuses on the use of MENs to non-invasively stimulate the deep brain neuronal activity via application of a low energy and low frequency external magnetic field to activate intrinsic electric dipoles at the cellular level through numerical simulations. Third, this dissertation describes the use of MENs to track the neuronal activities in the brain (non-invasively) using a magnetic resonance and a magnetic nanoparticle imaging by monitoring the changes in the magnetization of the MENs surrounding the neuronal tissue under different states. The potential therapeutic and diagnostic impact of this innovative and novel study is highly significant not only in HIV-AIDS, Cancer, Parkinson’s and Alzheimer’s disease but also in many CNS and other diseases, where the ability to remotely control targeted drug delivery/release, and diagnostics is the key.

On the adoption of privacy-enhancing technologies

We propose a model, based on the work of Brock and Durlauf, which looks at how agents make choices between competing technologies, as a framework for exploring aspects of the economics of the adoption of privacy-enhancing technologies. In order to formulate a model of decision-making among choices of technologies by these agents, we consider the following: context, the setting in which and the purpose for which a given technology is used; requirement, the level of privacy that the technology must provide for an agent to be willing to use the technology in a given context; belief, an agent’s perception of the level of privacy provided by a given technology in a given context; and the relative value of privacy, how much an agent cares about privacy in this context and how willing an agent is to trade off privacy for other attributes. We introduce these concepts into the model, admitting heterogeneity among agents in order to capture variations in requirement, belief, and relative value in the population. We illustrate the model with two examples: the possible effects on the adoption of iOS devices being caused by the recent Apple–FBI case; and the recent revelations about the non-deletion of images on the adoption of Snapchat.

Quando a morte antecede o nascimento: atuação do enfermeiro especialista em saúde materna e obstetrícia na assistência à mulher que vivência uma morte fetal

A perda gestacional é uma experiência dolorosa e complexa para a mãe/casal. O enfermeiro surge como promotor da adaptação á perda. Com esta intervenção, pretendo assegurar boas práticas de enfermagem na assistência às mulheres/casais em situação de perda gestacional. Foi realizado um estudo qualitativo em que se realizaram entrevistas a mulheres que vivenciaram perda gestacional e aos Enfermeiros Especialistas de Saúde Materna e Obstétrica como prestadores de cuidados. Os resultados mostram que os enfermeiros consideram a perda gestacional uma experiência difícil de vivenciar, identificando necessidades de formação. As mulheres referem diferenças na abordagem por parte dos enfermeiros aquando dos cuidados recebidos, falta de apoio e necessidade de encaminhamento após a alta hospitalar. Efetuou-se formação aos enfermeiros com peritos da área e desenvolveram-se procedimentos para uniformizar os cuidados. Foi criado um procedimento para uniformizar a prática e materiais de suporte para o apoio na prestação de cuidados de enfermagem; WHEN THE DEATH ANTECIPATES THE BIRTH: MIDWIVES' ROLE IN ASSISTANCE TO WOMENWHO EXPERIENCE FETAL DEATH. ABSTRACT: Pregnancy loss is a painful and complex experience to the mother/couple. The nurse is the promoting agent to the loss adaptation. With this project, I intend to ensure good nursing practices in assisting women/couples who experience a pregnancy loss. A qualitative study was performed, in which interviews were conducted to women who experienced a pregnancy loss and to nurse-midwives who provided care. Results demonstrated that nurse-midwives find pregnancy loss as a difficult experience, identifying educational needs. Women relate differences in the nurse-midwives’ approach during care, lack of support and the need of follow-up after hospital discharge. Nurse-midwives were subjected to training with experts and procedures were developed in order to standardize care. A practice standardizing procedure and educational materials were created to support nursing practice.

Characterization of medieval glass artefacts from Miranduolo site, Chiusdino, Italy

This archaeovitreological study deals with artefacts of Miranduolo site, Tuscany region (Italy), dated 1250-1350 AD. The Miranduolo site is a medieval hill-village dated from 7th to 14th century. The information obtained reveal that Miranduolo was under control of noble families, which displayed the social, economic and political power. It is marked by controlling the farmers and metal workers on the site, as well as having control over agricultural surpluses. No in situ glass workshop has been recovered, implying that the glass artefacts were imported. One aim of this work is application of SEM-EDS to visualize textural characteristics and thickness of the pristine glass and corrosion layers. Preliminary qualification and semi-quantification of major and minor chemical elements will provide the data on the glass group present and fluxes employed. The data obtained will be integrated with the one obtained by more sensitive techniques such as PIXE/PIGE and LA-ICP-MS. Twenty cross-sections of transparent glasses (colorless, azure, and different hues of yellow and) have been analyzed by VP-SEM. All the analyzed glasses display a homogenous matrix. Only four samples (MD 24, MD 139, MD 143, MD 259) show corrosion layers of various thickness with 2.25μm, 136-500 μm, 26.8 μm and 17.01 μm. EDS linescan analyses indicate strong depletion in the corrosion layers of Na and K, while Ca depletes to a minor extent. In general, both glass composition and the burial conditions were favorable for preservation. Samples can be classified as mainly plant ash Na-Ca-Si glasses made with both unpurified and purified Levantine ash. Only sample MD 243 is made from Barilla plant ash. Sample MD 139 cannot be classified into main compositional groups as K2O is 1.33 wt% and MgO 5.92 wt%. In 8 samples MnO content is lower than 0.8 wt%, meaning that in these samples MnO is naturally present. In other 12 samples, MnO above 0.8 wt% indicates deliberate addition as a decolorant agent to intentionally obtain different hues or the amount added was not successful in making the glass transparent. The results considering fluxes are compatible with archaeovitreological study from contemporary primary glass workshops in Tuscany. For determining the provenance of silica sources, further analysis with more sensitive techniques has to be carried out; Resumo: Este estudo “arqueovitreologia” lida com artefatos do local Miranduolo, região da Toscana (Itália), datados de 1250-1350 AD. O sitio de Miranduolo é uma colina vila medieval datada do séc.VII ao séc.XIV. As informações obtidas revelam que Miranduolo estava sob o controle de famílias nobres, que exibiu o poder social, económico e político. É marcado por controlar os agricultores e trabalhadores do metal no sitio, bem como ter controlo sobre os excedentes agrícolas. Não há na oficina de vidro in situ foi recuperado, o que implica que os artefactos de vidro foram importados. Um dos objetivos deste trabalho é a aplicação de SEM-EDS para visualizar características de textura e espessura das camadas de corrosão do vidro também como da áreas originais. qualificação preliminar e semi-quantificação de maiores e menores elementos químicos irá fornecer os dados sobre o grupo presente vidro e fluxos empregado. Os dados obtidos são integrados com os dados obtidos por meio de técnicas mais sensíveis, como PIXE / PIGE e LA-ICP-MS. Vinte secções transversais de vidros transparentes (incolor, azul celeste, e diferentes tons de amarelo) foram analisados por VP-SEM. Todos os vidros analisados exibir uma matriz homogénea. Apenas quatro amostras (MD 24, MD 139, MD 143, MD 259) mostram camadas de corrosão de várias espessuras com 2.25μm, 136-500μm, 26,8μm e 17,01μm. Análises Linescan EDS indicam forte esgotamento nas camadas de corrosão de Na e K, enquanto Ca esgota, em menor grau. Em geral, tanto a composição de vidro e as condições de depósito foram favoráveis para a preservação. As amostras podem ser classificados como vidros principalmente Na-Ca-Si feitas com cinzas de plantas do tipo levantino, não purificada e purificada. Apenas a amostra MD 243 é feita a partir de cinzas vegetais tipo “Barilla”. A amostra MD 139 não pode ser classificada em grupos principais de composição porque K2O é 1,33% em peso e MgO 5,92% em peso. Em 8 amostras, o teor de MnO é menor do que 0,8% em peso, o que significa que nestas amostras MnO está naturalmente presente. Em outras 12 amostras, MnO acima de 0,8% em peso indica adição intencional como um agente de colorante para obter intencionalmente diferentes matizes ou o valor acrescentado não foi bem sucedido em fazer o vidro transparente. Os resultados, considerando os fluxos são compatíveis com o estudo “arqueovitreologico” com as principais oficinas de vidro contemporâneos na Toscana. Para determinar a origem das fontes de sílica, uma análise mais aprofundada com técnicas mais sensíveis tem de ser levada a cabo.

Treatment with the vascular disruptive agent OXi4503 induces an immediate and widespread epithelial to mesenchymal transition in the surviving tumor

Epithelial to mesenchymal transition (EMT) is considered an important mechanism in tumor resistance to drug treatments; however, in vivo observation of this process has been limited. In this study we demonstrated an immediate and widespread EMT involving all surviving tumor cells following treatment of a mouse model of colorectal liver metastases with the vascular disruptive agent OXi4503. EMT was characterized by significant downregulation of E-cadherin, relocation and nuclear accumulation of b-catenin as well as significant upregulation of ZEB1 and vimentin. Concomitantly, significant temporal upregulation in hypoxia and the pro-angiogenic growth factors hypoxia-inducible factor 1-alpha, hepatocyte growth factor, vascular endothelial growth factor and transforming growth factor-beta were seen within the surviving tumor. The process of EMT was transient and by 5 days after treatment tumor cell reversion to epithelial morphology was evident. This reversal, termed mesenchymal to epithelial transition (MET) is a process implicated in the development of new metastases but has not been observed in vivo histologically. Similar EMT changes were observed in response to other antitumor treatments including chemotherapy, thermal ablation, and antiangiogenic treatments in our mouse colorectal metastasis model and in a murine orthotopic breast cancer model after OXi4503 treatment. These results suggest that EMT may be an early mechanism adopted by tumors in response to injury and hypoxic stress, such that inhibition of EMT in combination with other therapies could play a significant role in future cancer therapy.

Refining the process of agent selection through understanding plant demography and plant response to herbivory

Understanding plant demography and plant response to herbivory is critical to the selection of effective weed biological control agents. We adopt the metaphor of 'filters' to suggest how agent prioritisation may be improved to narrow our choices down to those likely to be most effective in achieving the desired weed management outcome. Models can serve to capture our level of knowledge (or ignorance) about our study system and we illustrate how one type of modelling approach (matrix models) may be useful in identifying the weak link in a plant life cycle by using a hypothetical and an actual weed example (Parkinsonia aculeata). Once the vulnerable stage has been identified we propose that studying plant response to herbivory (simulated and/or actual) can help identify the guilds of herbivores to which a plant is most likely to succumb. Taking only potentially effective agents through the filter of host specificity may improve the chances of releasing safe and effective agents. The methods we outline may not always lead us definitively to the successful agent(s), but such an empirical, data-driven approach will make the basis for agent selection explicit and serve as testable hypotheses once agents are released.

Letter written by Napoleon Buonaparte (Bonaparte) to Guillaume Thomas Francois Raynal, June 24, 1790

Translation: Sir, It will probably be difficult for you to remember among the many strangers who annoy you with their admiration of a person to whom you kindly made civilities last year1 during a pleasant conversation about Corsica. I would be grateful if you could take a look at this sketch of his history.2 I present here the first of two letters. If you agree to them, I will send you the end. My brother, whom I recommend not to forget his deputies' commission to escort Paoli to his country,3 and to come and receive a lesson in virtue and humanity, will give them to you. I respectfully your most humble and obedient servant.4 Buonaparte, artillery officer Ajaccio, [Corsica] June 24 the first year of freedom [1790]5 1 Relations between Napoleon and Raynal have begun in 1789, which seems to confirm a confidence to Las Cases ( Memorial of St. Helena , La Pléiade , vol. I, p. 83) . 2 Latest version of history project of Corsica : Letters on Corsica to Abbe Raynal . 3 Joseph is part of a delegation sent by the city of Ajaccio to host Paoli 's return from exile in London . In doing so he has to go through Marseille where Raynal resides. 4 Shipping autograph, National Archives , 400 AP Biography 1. In the first years of Napoleon Bonaparte (1840) , Coston gives a rough version of this letter that it dates from 1786 , which is impossible because Raynal did not return to France that ' in 1787. Published for the first time in the Memories of Lord Holland (1851) , shipping is now kept in the national Archives Napoleons funds . 5 The letter is dated "June 24, the first year of freedom" (the word "freedom" is underlined twice). Given the dates of stay in Corsica Napoleon, it seems that is present in Ajaccio the month of June in 1790.
