Os desafios de competitividade têm levado as organizações a estruturarem estratégias robustas de crescimento, consolidando a sua atuação em determinados setores ou mesmo levando à expansão das suas atividades para novos mercados e regiões geográficas. As combinações empresariais, caracterizadas por aquisições e fusões, tornam-se cada vez mais relevantes para a viabilização destas estratégias e passam a fazer parte integrante da agenda dos líderes empresariais. Diante dos baixos indicadores de efetividade verificados em operações desta natureza, torna-se importante refletir sobre a sua gestão e identificar as condições necessárias para que as novas configurações organizacionais implementadas resultem alinhadas às orientações estratégicas que motivaram a realização destas transações. Este trabalho insere-se neste tema ao propor um modelo de gestão da mudança organizacional advinda de combinações empresariais e a sua aplicação no setor de ciências da vida. As oportunidades características deste novo setor, com fronteiras ainda pouco estabelecidas, têm gerado uma série de movimentos de combinação em empresas tradicionais do setor químico, em busca de crescimento ou obtenção de indicadores mais elevados de competitividade. Ao propor o modelo de gestão...

Este trabalho busca analisar as condições de trabalho de pesquisadores no Brasil e na Argentina com o intuito de investigar a relação entre tais condições, a capacidade acadêmica e os indicadores ligados à ciência básica e aplicada e à inovação dos dois países. Por meio da análise do conteúdo de seis entrevistas com pesquisadores, sendo três argentinos e três brasileiros, no campo das ciências médicas e biomédicas, além do estudo da bibliografia sobre as mudanças no mundo do trabalho e no campo da ciência e da tecnologia, procuramos identificar em que a situação dos dois países se assemelha ou se distancia. Concluímos que a pressão pelo aumento da produtividade acadêmica tem os mesmos moldes nos dois países, assim como a implantação de critérios de avaliação voltados para o crescimento da produção científica foi acelerada na década de 1990, na esteira do receituário neoliberal que marcou a política e a economia do continente. Embora os dois países venham experimentando um crescimento nos recursos investidos em ciência e tecnologia, há diferenças importantes entre eles, relacionadas à regularidade da oferta de recursos, com vantagem para o Brasil, e à disponibilidade de recursos humanos altamente qualificados...

Greenhouse gas emission magnitudes, trends, and source contributions are highly uncertain, particularly at sub-national scales. As the world becomes increasingly urbanized, one potential strategy for reducing these uncertainties is to focus atmospheric greenhouse gas measurements in urban areas, where a multitude of emission processes occur, imposing a strong and persistent gradient in the local atmosphere, and contributing a significant fraction of global anthropogenic greenhouse gas emissions. This thesis explores the capabilities and requirements for characterizing and quantifying greenhouse gas fluxes in urban environments using atmospheric measurements and models. The first chapter uses an existing dataset of atmospheric carbon dioxide measurements from Salt Lake City, Utah to assess the capacity of an atmospheric measurement and modeling framework to detect changes in emissions from a city in the context of an emissions verification framework. The results of this work are then used to explore an alternative or complementary measurement strategy of atmospheric column measurements for urban emissions detection, which would be less sensitive than point measurements to the large variability present in urban atmospheres, but would also have more stringent accuracy requirements. The second chapter describes the development and maintenance of a network of greenhouse gas measurement stations in the Boston urban region...

The physicochemical properties of the secondary organic materials (SOMs) that constitute the particle phase have potentially important consequences for the growth, the reactivity, and ultimate fate of atmospheric organic aerosols, thereby affect climate, human health and visibility. A quantitative analysis of the physicochemical properties of the SOMs is important, but challenging. This thesis presents laboratory studies of α-pinene derived SOMs, which is one of the major components of secondary organic aerosols (SOAs) in the forests, by combing a flow tube reactor, aerosol particle mass analyzer (APM) and other online/offline measurement techniques. A water-jacketed constant temperature flow tube reactor was built to produce SOM particles grown from either condensation or coagulation. Different ratios of α-pinene enantiomers were mixed and injected into the flow tube reactor for dark ozonolysis. A matrix of organic precursor and ozone concentrations was designed and tested in order to determine the optimal concentration to switch between condensation and coagulation. Results show that at 51 ± 1 ppm O3, condensation is the dominant growth mechanism when the α-pinene concentration is 0.125 ± 0.001 ppm, and coagulation is the dominant growth mechanism when the α-pinene concentration increases to 1.00 ± 0.03 ppm. A combination of both growth mechanisms is observed when the α-pinene concentration is in between the described values. The study also proposed and tested the hypothesis that a 50:50 mixture of α-pinene enantiomers may result in SOM particles that have different physical properties...

Cette thèse porte sur l’évaluation de la cohérence du réseau conceptuel démontré par des étudiants de niveau collégial inscrits en sciences de la nature. L’évaluation de cette cohérence s’est basée sur l’analyse des tableaux de Burt issus des réponses à des questionnaires à choix multiples, sur l’étude détaillée des indices de discrimination spécifique qui seront décrits plus en détail dans le corps de l’ouvrage et sur l’analyse de séquences vidéos d’étudiants effectuant une expérimentation en contexte réel. Au terme de ce projet, quatre grands axes de recherche ont été exploré. 1) Quelle est la cohérence conceptuelle démontrée en physique newtonienne ? 2) Est-ce que la maîtrise du calcul d’incertitude est corrélée au développement de la pensée logique ou à la maîtrise des mathématiques ? 3) Quelle est la cohérence conceptuelle démontrée dans la quantification de l’incertitude expérimentale ? 4) Quelles sont les procédures concrètement mise en place par des étudiants pour quantifier l’incertitude expérimentale dans un contexte de laboratoire semi-dirigé ? Les principales conclusions qui ressortent pour chacun des axes peuvent se formuler ainsi. 1) Les conceptions erronées les plus répandues ne sont pas solidement ancrées dans un réseau conceptuel rigide.

This study develops a way to use the technology of video games to help teach people the violin. The unique characteristics of this research are to create a visual representation for music for violinists, to utilize pedagogy for violin education within a video game, and to use the Fast Fourier Transform to process input from an actual acoustic instrument and use the data to track user progress. Music games like JamGuru [9], Rocksmith [19], LittleBigStar [13], and Rock Band [18] have made strides in these areas of research; however, most of these technologies have not been applied to the violin. Expected results are that students' progress rate will increase as a result of playing the game. The input processing used in this research could be applied to areas where sound recognition is important. Furthermore, the concept of an adaptable game can be applied to other academic subjects.

The report of the World Commission on Forests and Sustainable Development [(1999) Our Forests, Our Future: Report of the World Commission on Forests and Sustainable Development (Cambridge Univ. Press, Cambridge, U.K.)] has called attention to a global need to restore the functional integrity of nature. The assumption that the biophysical world is capable of supporting any intensity of economic and political activity is now obviously wrong. The failures are seen as global changes such as the global climatic disruption now underway. The global disruptions are the product of cumulative local disruptions. Despite a conspicuous need, the scientific community has been slow in developing tools to appraise the functional integrity of landscapes. The proposal is advanced that the first steps deal with forests because they are so large in their influences on global biophysics. Analyses carried out by the commission are elaborated here as an index of functional integrity in the forest zone. The proposal is based on a simple, transparent approach. The scale is 0–100 with 100 as the nominal climax. Decrements and increments are applied as the structural and functional integrity of the landscape varies with whatever cause. The unit of area for these trials has been 10...

The brain representation of the body, called the body schema, is susceptible to plasticity. For instance, subjects experiencing a rubber hand illusion develop a sense of ownership of a mannequin hand when they view it being touched while tactile stimuli are simultaneously applied to their own hand. Here, the cortical basis of such an embodiment was investigated through concurrent recordings from primary somatosensory (i.e., S1) and motor (i.e., M1) cortical neuronal ensembles while two monkeys observed an avatar arm being touched by a virtual ball. Following a period when virtual touches occurred synchronously with physical brushes of the monkeys' arms, neurons in S1 and M1 started to respond to virtual touches applied alone. Responses to virtual touch occurred 50 to 70 ms later than to physical touch, consistent with the involvement of polysynaptic pathways linking the visual cortex to S1 and M1. We propose that S1 and M1 contribute to the rubber hand illusion and that, by taking advantage of plasticity in these areas, patients may assimilate neuroprosthetic limbs as parts of their body schema.

Accurate and rapid identification of perturbed pathways through the analysis of genome-wide expression profiles facilitates the generation of biological hypotheses. We propose a statistical framework for determining whether a specified group of genes for a pathway has a coordinated association with a phenotype of interest. Several issues on proper hypothesis-testing procedures are clarified. In particular, it is shown that the differences in the correlation structure of each set of genes can lead to a biased comparison among gene sets unless a normalization procedure is applied. We propose statistical tests for two important but different aspects of association for each group of genes. This approach has more statistical power than currently available methods and can result in the discovery of statistically significant pathways that are not detected by other methods. This method is applied to data sets involving diabetes, inflammatory myopathies, and Alzheimer's disease, using gene sets we compiled from various public databases. In the case of inflammatory myopathies, we have correctly identified the known cytotoxic T lymphocyte-mediated autoimmunity in inclusion body myositis. Furthermore, we predicted the presence of dendritic cells in inclusion body myositis and of an IFN-α/β response in dermatomyositis...

The widely used Born model describes the electrostatic response of continuous media using static dielectric constants. However, when applied to a liquid environment, a comparison of Born model predictions with experimental values (e.g., transfer free energies and pKa shifts) found that agreement is only achieved by using physically unrealistic dielectric constants for proteins, lipids, etc., and/or equally unrealistic atomic radii. This leads to questions concerning the physical origins for this failure of the Born model. We partially resolve this question by applying the Langevin–Debye (LD) model of a continuous distribution of point, polarizable dipoles, a model that contains an added dependence of the electrostatic response on the solvent's optical dielectric constant and both gas- and liquid-phase dipole moments, features absent in the Born model to which the LD model reduces for weak fields. The LD model is applied to simple representations of three biologically relevant systems: (i) globular proteins, (ii) lipid bilayers, and (iii) membrane proteins. The linear Born treatment greatly overestimates both the self-energy and the transfer free energy from water to hydrophobic environments (e.g., a protein interior). By using the experimental dielectric constant...

Online labor markets such as Amazon Mechanical Turk (MTurk) offer an unprecedented opportunity to run economic game experiments quickly and inexpensively. Using Mturk, we recruited 756 subjects and examined their behavior in four canonical economic games, with two payoff conditions each: a stakes condition, in which subjects' earnings were based on the outcome of the game (maximum earnings of $1); and a no-stakes condition, in which subjects' earnings are unaffected by the outcome of the game. Our results demonstrate that economic game experiments run on MTurk are comparable to those run in laboratory settings, even when using very low stakes.; Engineering and Applied Sciences; Psychology

Transient electric fields driven by intense lasers and particle beams play a key role in a number of applications from plasma-based particle accelerators to implosion dynamics of inertial fusion targets. Here, a method to map the 3D transient field structures with high resolutions both in time and space by use of picosecond electron bunches is presented. It is applied to measure the transient field evolution induced at a solid surface irradiated by a short pulse laser. This method can be applied to monitor field structures with much higher strength, which may find wide application in relevant research fields.

We study the bifurcation and chaos scenario of the macro-magnetization vector in a homogeneous nanoscale-ferromagnetic thin film of the type used in spin-valve pillars. The underlying dynamics is described by a generalized Landau-Lifshitz-Gilbert (LLG) equation. The LLG equation has an especially appealing form under a complex stereographic projection, wherein the qualitative equivalence of an applied field and a spin-current induced torque is transparent. Recently chaotic behavior of such a spin vector has been identified by Zhang and Li using a spin polarized current passing through the pillar of constant polarization direction and periodically varying magnitude, owing to the spin-transfer torque effect. In this paper we show that the same dynamical behavior can be achieved using a periodically varying applied magnetic field, in the presence of a constant DC magnetic field and constant spin current, which is technically much more feasible, and demonstrate numerically the chaotic dynamics in the system for an infinitely thin film. Further, it is noted that in the presence of a nonzero crystal anisotropy field chaotic dynamics occurs at much lower magnitudes of the spin-current and DC applied field.; Comment: 8 pages, 7 figures.

The ability of nonlinear dynamical systems to process incoming information is a key problem of many fundamental and applied sciences. Information processing by computation with attractors (steady states, limit cycles and strange attractors) has been a subject of many publications. In this paper we discuss a new direction in information dynamics based on neurophysiological experiments that can be applied for the explanation and prediction of many phenomena in living biological systems and for the design of new paradigms in neural computation. This new concept is the Winnerless Competition (WLC) principle. The main point of this principle is the transformation of the incoming identity or spatial inputs into identity-temporal output based on the intrinsic switching dynamics of the neural system. In the presence of stimuli the sequence of the switching, whose geometrical image in the phase space is a heteroclinic contour, uniquely depends on the incoming information. The key problem in the realization of the WLC principle is the robustness against noise and, simultaneously, the sensitivity of the switching to the incoming input. In this paper we prove two theorems about the stability of the sequential switching and give several examples of WLC networks that illustrate the coexistence of sensitivity and robustness.; Comment: 31 pages...

We investigate the ground state of a uniaxial ferromagnetic plate with perpendicular easy axis and subject to an applied magnetic field normal to the plate. Our interest is the asymptotic behavior of the energy in macroscopically large samples near the saturation field. We establish the scaling of the critical value of the applied field strength below saturation at which the ground state changes from the uniform to a branched domain magnetization pattern and the leading order scaling behavior of the minimal energy. Furthermore, we derive a reduced sharp-interface energy giving the precise asymptotic behavior of the minimal energy in macroscopically large plates under a physically reasonable assumption of small deviations of the magnetization from the easy axis away from domain walls. On the basis of the reduced energy, and by a formal asymptotic analysis near the transition, we derive the precise asymptotic values of the critical field strength at which non-trivial minimizers (either local or global) emerge. The non-trivial minimal energy scaling is achieved by magnetization patterns consisting of long slender needle-like domains of magnetization opposing the applied field; Comment: 38 pages, 7 figures, submitted to J.

The kidney's major role in filtration depends on its high blood flow, concentrating mechanisms, and biochemical activation. The kidney's greatest strengths also lead to vulnerability for drug-induced nephrotoxicity and other renal injuries. The current standard to diagnose renal injuries is with a percutaneous renal biopsy, which can be biased and insufficient. In one particular case, biopsy of a kidney with renal cell carcinoma can actually initiate metastasis. Tools that are sensitive and specific to detect renal disease early are essential, especially noninvasive diagnostic imaging. While other imaging modalities (ultrasound and x-ray/CT) have their unique advantages and disadvantages, MRI has superb soft tissue contrast without ionizing radiation. More importantly, there is a richness of contrast mechanisms in MRI that has yet to be explored and applied to study renal disease.

The focus of this work is to advance preclinical imaging tools to study the structure and function of the renal system. Studies were conducted in normal and disease models to understand general renal physiology as well as pathophysiology. This dissertation is separated into two parts--the first is the identification of renal architecture with ex vivo MRI; the second is the characterization of renal dynamics and function with in vivo MRI. High resolution ex vivo imaging provided several opportunities including: 1) identification of fine renal structures...

Real Social Science presents a new, hands-on approach to social inquiry. The theoretical and methodological ideas behind the book, inspired by Aristotelian phronesis, represent an original perspective within the social sciences, and this volume gives readers a set of studies exemplifying what applied phronesis looks like in practice. Flora Cornish finds that the book will benefit scholars, researchers and students who want to make a difference in practice, not just in the academy

A growing body of research shows that the overall quality of teaching and learning is improved when learners have the opportunity to become actively involved in the learning process through which ample opportunities are given to question, apply and consolidate new knowledge. With the dawning of a new South Africa in 1994, more emphasis was placed on learner-centred instruction and assessment which is the reason why policy documents such as the National Curriculum Statement (NCS) and the Curriculum and Assessment Policy Statement (CAPS) endorsed this educational approach. The aim of this study is to investigate through the observation of trainee teachers to what extent History and Social Sciences teachers have adjusted from their predominately traditional educational paradigm of transmitted and absorbed knowledge by passive learners to employ different learner-centred instructional and assessment practices that emphasise the responsibility of learning into actively engaging learners. By means of a structured questionnaire a small scale study (n=51) was done in urban, rural, township, and private schools in the North West and Gauteng provinces. The findings, inter alia, suggest that although History and Social Sciences teachers showed a willingness to utilise some of the learner-centred instruction strategies...
