Full textAbstract:
In this thesis the component parts of Marx's method are identified and clarified, his use of dialectics and materialism examined, and the scientific standing of his method assessed. It is argued that Marx's method is coherent, valid and scientific, and is based on a dialectical and materialist philosophy. The key themes of Marx's method identified include critique, abstraction, essence and appearance, inversion, and practice. Six theses of Marx's materialism are put forward: the realism thesis, the primacy of matter thesis, the naturalism thesis, the historical materialism thesis, the praxis thesis and the materialist methodology thesis. The core elements of dialectics are identified as change, connection and contradiction, and the outline of a non-Hegelian dialectic is sketched out. It is contended that the interpretations of dialectics and materialism presented constitute the underpinnings of Marx's method. The relations between the component parts of his method, and between them and the dialectical and materialist philosophical foundation are indicated, and the overall coherence of Marx's method asserted. Four conceptions of science - scientific positivism, critical rationalism, conventionalism and scientific realism - are identified and analysed, and Marx's method is compared and contrasted with them. Arguments for Marxism's scientificity are examined and assessed, and it is contended that Marx's method is compatible with the scientific realist conception of science.

Science benefits from substantial cognitive diversity because cognitive diversity promotes scientific progress toward greater accuracy. Without diversity of goals, beliefs, and methods, science would neither generate novel discoveries nor certify representations with its present effectiveness. The revolution in geosciences is a principal case study.The role of cognitive diversity in discovery is explored with attention to computational results. Discovery and certification are inseparable. Moreover, diverse scientific groups agree convergently, and their agreements manifest an explanatory defense akin to the explanatory defense of realism. Scientists accept representations as a matter of their instrumental success in individual scientific research. Because scientists are diverse, this standard of acceptance means that widespread acceptance involves widespread instrumental success. This success is best explained through the accuracy of topics of agreement.The pessimistic induction is addressed; it fails to undermine the explanatory defense because past scientific successes don't resemble present ones in their degree of instrumental success; to make this point, instrumental success of representations of caloric and of oxygen are compared.Cognitive diversity challenges the methodological uniformity of scientific practice. Science lacks uniform methods and aims, and it ought to. It is argued that there is no sound basis for thinking that science aims. Moreover, the growth of science itself is not the growth of knowledge. Scientific communities rather than individual scientists are the main certifiers of scientific results. Hence, since knowledge requires a certifying belief formation process but the process relevant to science is not realized individually, science does not progress toward knowledge. The epistemology of science is socialized, but remains broadly realist because, even without a method of inquiry, science develops accurate representations of unobservable nature.

Full textAbstract:
The case study as a scientific method is, and has been for a long time, a subject of heavy discussion in the scientific community. Some scientists disregard the study completely and argue that it’s nothing more than story-telling, while others claim that the case study is the most relevant research method there is. As with all scientific methods case studies have both advantages and disadvantages and the aim of this study is to present and discuss these.

Apesar dos inúmeros benefícios proporcionados pela prática científica ao mundo nos últimos anos, os profissionais e estudantes da Psicologia ainda se mostram resistentes ao uso do método científico na área. As origens de tais objeções e as variáveis que as influenciam ainda são incertas, fazendo-se necessário estudos que busquem investiga-las. A ideia principal apresentada neste estudo é a de que as concepções de ciência e método científico entre os profissionais e estudantes brasileiros de Psicologia são insuficientes. Para se testar as hipóteses derivadas dessa ideia, buscou-se avaliar essas concepções por meio de duas perguntas abertas sobre o tema e um questionário sociodemográfico. A amostra de respondentes ficou composta por 791 pessoas, estudantes (n = 407) e profissionais (n = 384) de todo Brasil, com idades entre 17 a 67 anos (M = 29,07; DP = 9,02), sendo 68,5 por cento do sexo feminino. As respostas foram analisadas por meio da Classificação Hierárquica Descendente e Análise Fatorial de Correspondências, com o auxílio da interface IRaMuTeQ. Os resultados revelaram que os participantes possuem concepções muito diversas em relação à ciência e ao método científico, predominando a noção de que a ciência é um método de aquisição de conhecimento, porém sem entrar em muitos detalhes sobre como se dá o funcionamento desse método. Ressalta-se a importância de um aprendizado aprofundado sobre metodologia científica nos cursos de Psicologia.
Despite the numerous benefits of scientific practice to the world in recent years, the professionals and students of the Psychology are still resistant to the use of the scientific method in this area. The origins of such objections and the variables that influence them are uncertain, requiring studies to investigate them. The main idea presented in this study is that the conceptions of science and scientific method among Brazilian professionals and students of Psychology are insufficient. In order to test the hypotheses derived from this idea, the aim of this study was to evaluate the psychology professionals and student s conceptions about science and scientific method through two open questions and a sociodemographic questionnaire. The sample of respondents was composed of 791 people, students (n = 407) and professionals (n = 384) from Brazil, aged between 17 and 67 years (M = 29.07, SD = 9.02), 68,5 percent women. The analysis of the texts occurred through the Descending Hierarchical Classification and Correspondence Factor Analysis with the aid of the IRaMuTeQ, an interface of textual analysis. The analysis revealed that the participants have very different conceptions about science and scientific method, dominating the notion that science is a method of acquiring knowledge, but without more details about how this method works. It is important to emphasize the importance of learning about scientific methodology in Psychology courses.

Full textAbstract:
Adolf Grunbaum and others have criticised Freudian Psychoanalysis (FPA) methodologically, because of the potential inferential liabilities of testing causal psychoanalytic claims in the interview sessions. Also, Grunbaum has prescribed scientific experimentation (especially prospective group-comparison studies) as the best means of overcoming these methodological deficiencies. I argue, firstly, that the opportunities for making reliable inferences (including some causal ones) in psychotherapeutic interviews are better than Grunbaum canvasses, though I do this for a theoretically weaker form of psychodynamic psychology than FPA (i.e. General Psychotherapeutic Counselling, or GPC). Secondly, 1 argue that there are substantial problems with and limitations of experimental methodology, both in itself and when applied to test the specific kinds of hypotheses psychotherapists are interested in. Grunbaum and others fail to draw adequate attention to the generic problems of experimentation. I argue that insofar as the acquisition of psychological knowledge is concerned, it is legitimate to distinguish two broad categories of inductive processes capable of providing it: (i) folk-psychological (or FP-) reasoning; and (ii) experimentation (including epidemiology). (By 'FP-reasoning' I mean the largely inherent capacity that human beings have for making inferences about the psychology of others or themselves, in folk-psychological terms.) I argue that FP-reasoning is in some respects inductively superior to experimentation. If this is correct, there ought to be no automatic methodological priority granted to experimentation in psychology and psychiatry. Various topics related to the above are developed. For example; (i) some problems of the practical application to the psychotherapeutic domain of a principle of causal relevance (provided by Grunbaum) are examined; (ii) a sketch for a model of testing for causal relevance in the special case of insults (provided by Grunbaum) is criticised, and an alternative model is proposed; (iii) some general problems of justifying FP knowledge-claims are discussed, and sceptical attitudes towards the acquisition of folk-psychological knowledge are criticised.

Full textAbstract:
The thesis explores the complex area between preservation of museum collections, and the need to allow access to the collections and the artefacts for researchers. The focus is on archaeological collections, and inorganic materials in particular. The aim is to illustrate the problems, as well as the opportunities, of archaeological scientific analysis when combined with museological sciences such as materiality and material culture studies, theories of object biographies, the concept of objects as actors, and the issue of silent objects. Exploring the exchange between the museological and the natural sciences to promote enhanced usage of collection artefacts, and to explore whether there are real barriers or if they are perceived due to a lack of mutual understanding. Methodologically it is a text based analysis of the research situation internationally and nationally in Sweden, with a case study comprised of observation of a research team that at the same time were making archaeometallurgical analyses of bronze age objects, and interviews with a small group connected to the areas of interest for this thesis. The sources have consisted of the material generated by the case study, as well as the text material used to provide the necessary background. By using text analysis, Actor-network theory, observation, and interviews, the discussions can revolve around the theoretical perspectives of materiality, object biography and silent objects, with the premise that sample analyses could bring back some context to an artefact. The findings indicate that the museum sector and other disciplines would greatly benefit from closer collaborations with each other and work more interdisciplinary. Museum collections harbour artefacts that could enrich the collective disciplines with their informative values, and with a mass of sampled and analysed context-less artefacts, new and fascinating patterns could emerge, leading to new discoveries. The findings also show that, in archaeology, this is already in motion, and the hope is that this develops on a larger scale in the museum sector as well.Den här uppsatsen undersöker det snåriga område mellan museers plikt att bevara samlingarna samt behovet att tillåta åtkomst för forskare till samlingarna och föremålen. Fokus ligger på arkeologiska samlingar, och oorganiskt material i synnerhet. Syftet är att belysa problemen, samt de möjligheter som arkeologisk vetenskaplig analys har att ge i kombination med museivetenskapliga begrepp såsom materialitet och materiell kultur, teorier om objektbiografi, objekt som aktörer och ”tysta” föremål. Uppsatsen utforskar utbyten mellan musei- och naturvetenskap som främjar ökad användning av föremål i samlingar, och undersöker om det finns verkliga hinder i utbytet eller om de endast är upplevda på grund av en bristande ömsesidig förståelse. Metodologiskt är det en textbaserad analys av forskningsläget internationellt och nationellt i Sverige, med en fallstudie bestående av observation av en forskargrupp som samtidigt gjorde arkeometallurgiska analyser av bronsåldersföremål, och intervjuer med en liten grupp personer med koppling till intresseområdena för denna uppsats. Källorna består av det material som genererats av fallstudien, samt den litteratur som gett den nödvändiga bakgrunden. Genom att använda textanalys, Actor-network theory, observation och intervjuer, kretsar diskussionerna runt teoretiska perspektiv som materialitet och materiell kultur, objektbiografi och ”tysta” föremål utifrån förutsättningen att analys kan återföra lite av en artefakts kontext. Resultaten visar på att museisektorn och andra discipliner i hög grad skulle tjäna på ett närmare samarbete och att arbeta mer tvärvetenskapligt. Museisamlingar inhyser föremål som skulle kunna berika de samlade disciplinerna med sina informativa värden, och med en mängd provtagningar och analyser av kontextlösa föremål kan nya och fascinerande mönster framträda, vilket i sin tur kan leda till nya upptäckter. Resultaten visar också att detta redan är satt i rörelse inom åtminstone arkeologin, men förhoppningen är att detta även kan ske i större skala inom museisektorn.

Doctoral thesis, Alma Mater Studiorum - Università di Bologna, 2018. http://amsdottorato.unibo.it/8330/1/giovannini_elisabettacaterina_tesi.pdf.
Full textAbstract:
This research project takes up the challenge of creating a system to document transparency of processes creating virtual 3D reconstructions. The virtual reconstruction of artefacts just designed, no longer existing, or nor fully documented is obviously a subjective process that simplifies a visualization of the original one. Nowadays, due to a growing number of multidisciplinary projects, scholars commonly recognize the importance of transparency in 3D virtual reconstructions.
The goal of this research project is defining a methodological procedure focused on the validation of the 3D reconstructive model and finding a methodological solution to visualize its multiple representations, defining standards from data processing through documentation to visualization of each 3D hypothetical reconstruction of Cultural Heritage (CH) artefacts.
Transparency and traceability of interpretation processes are necessary for a better understanding of knowledge embodied by 3D models and their visualizations. Transparency is also necessary for interdisciplinary communication and evaluation of results for the benefit of future generations.
The problem of interpretation which features reconstructions where multidisciplinary approaches is crucial to re-use information by those who own a different background but are called to collaborate on the same project.
In any research related to virtual reconstructions, the first step, acquiring a “pre-knowledge”, it is necessary to define a system where everyone can be user and creator of traceable knowledge.
The proposed methodology, named ”Virtual Reconstruction Information Management” (VRIM), aspires to systematize some general processes related to 3D Virtual Reconstructions (VR) and the management of data information related to those models.

Cheng, Mei-lin, and 鄭美蓮. "The effect of teacher questioning and the "questioning-exploration-experience" learning method on early scientific thinking." Thesis, The University of Hong Kong (Pokfulam, Hong Kong), 2011. http://hub.hku.hk/bib/B47055431.
Full textAbstract:
The “Questioning-Exploration-Experience” (QEE), a teaching and learning method underpinned by constructivist theory, was developed by Cheng and further refined by Cheng and Chan in 2001. This thesis documents and evaluates the effectiveness of five- to six-year-old children’s learning when a teacher used this method to promote children’s understanding of the concept of (air) motion. The evaluation was conducted in a preschool operated by a tertiary institution in Hong Kong, and a teacher who was experienced in using the QEE method and her 14 students participated in the study. They were observed for six days over a period of one month when children were working on a task of making a wind bell.
Under the QEE method, the children began the inquiry process by posing questions about constructing the wind bell. They then formulated hypotheses, tested them through exploration, and refined their questions repeatedly. The children reflected on their learning experiences in order to generate new questions. Teacher questioning was also a critical aspect of this process. The children and teacher spent a total of 323 minutes on the task and the sessions were videotaped. There was a total of 2,927 utterances in 863 conversational turns, and these were analyzed to examine the relationship between the levels of teacher questioning and the children’s responses to reflect the levels of children thinking. There were five of these levels identified. The first three are considered to involve lower-order thinking: level 1 ("yes/no"); level 2 ("what"); and level 3 (“elaborate") questions and responses. The next two can be considered as higher-order thinking: level 4 (“logical”) and level 5 ("critical") questions and responses. The results indicated that the teacher dominated the interactions and spoke 43% of the time, while children spoke for the remaining time (57%). Of the 139 minutes during which the teacher talked, she spent 97 minutes (70% of the time) posing 887 questions: level 1 was used the most often accounting for 41% of the interactions, followed by level 5 (17%), level 2 (16%), level 3 (14%), and level 4 (12%). The total time for which the children spoke was 184 minutes with 1653 responses. Children gave level 3 responses (28%) most frequently, followed by levels 2 (27%), 1 (26%), 5 (12%), and 4 (7 %), respectively.
The relationship between the teacher’s questions and children’s responses was analyzed. An exact correspondence between the level of teacher thinking and children’s responses occurred 46% of the time (398 turns). Simply put, when the teacher asked a question requiring a “what” response, the child typically gave “what” information. Within the 398 turns, 41% of this direct correspondence occurred at level 1, followed by 20% at level 2, 17% at level 5, 13% at level 3, and 9% at level 4. The greatest number of correspondences occurred with questions that required “yes/no” responses, and the least with “logical” questions.
In the QEE inquiry process, the teacher’s questioning had a strong influence on the children’s scientific thinking and played a critical role in promoting children’s knowledge construction. The teacher used questioning to define an area of inquiry, specify a problem to be solved, lead children to test hypotheses, evaluate their results and determine their understanding at various points during the process. Questioning, by both the teacher and the children, was critical in promoting the children’s scientific understanding.
The impact of QEE in fostering conceptual change in knowledge construction was traced along three paths. The first path in the questioning defined the central question of inquiry. The second path, exploration, was concerned with identifying the information needed to solve the problem. The third path, experience, involved restructuring the concepts of the central question to apply the new understanding in a new situation.
Findings also suggest that children’s knowledge construction is signified by the achievement of four elements: identification of a central question for inquiry, evaluation of the question about learning, provision of ways in which to answer the question, and critical reasoning.published_or_final_version

Full textAbstract:
Thesis advisor: Richard Cobb-StevensThesis advisor: Jean-Luc Solere
This dissertation attempts to locate the origins of Descartes' concept of mind in his early, unfinished treatise on scientific method, the Regulae ad directionem ingenii. It claims that one can see, in this early work, Descartes' commitment to substance dualism for methodological reasons. In order to begin an analysis of the Regulae, one must first attempt to resolve textual disputes concerning its integrity and one must understand the text as a historical work, dialectically situated in the tradition of late sixteenth and early seventeenth century thought. The dissertation provides this historical backdrop and textual sensitivity throughout, but it focuses on three main themes. First, the concept of mathesis universalis is taken to be the organizing principle of the work. This methodological principle defines a workable technique for solving mathematical problems, a means for applying mathematics to natural philosophical explanations, and a claim concerning the nature of mathematical truth. In each case, the mathesis universalis is designed to fit the innate capacities of the mind and the objects studied by mathesis are set apart from the mind as purely mechanical and geometrically representable objects. Second, Descartes' account of perceptual cognition, the principles of which are found in the Regulae, is examined. In this account, Descartes describes perception as a mechanical process up to the moment of conscious awareness. This point of awareness and the corresponding actions of the mind are, he claims, independent from mechanical principles; they are incorporeal and cannot be explained reductively. Finally, when Descartes outlines the explanatory bases of his natural science, he identifies certain "simple natures." These are the undetermined categories according to which actual things can be known. Descartes makes an explicit distinction between material simples and intellectual simples. It is argued that this distinction suggests a difference in kind between the sciences of the material world and the science or pure knowledge of the intellectual world. Though the Regulae is focused on physical or material explanations, there is a clear commitment to distinguishing this type of explanation from the explanation of mental content and mental acts. Hence, the Regulae demonstrates Descartes' early, methodological commitment to substance dualism

There is great potential for study of the experience of film by incorporating scientific research into the theorising process. In this work I outline my own values for theoretical work and provide discussion of the methodological goals and practices I will employ to utilise scientific research in film theorising and to meaningfully engage with that work. This includes a focus on strong argumentation, engagement with a broad scope of study on film, the production of applicable and assessable theories as well as robust theory construction. In addition to a description of practical applications towards these goals, the thesis will detail ways that a theorist may engage scientific work without being an expert in that field themselves. The work will examine the concept of ‘persistence of vision’ as a historical case study of the relationship between film theorising and scientific work. This includes a detailed examination of the evolution of different explanations for phenomena related to visual persistence and motion perception. Following this is a critique of the use of ‘persistence of vision’ within historical film theories as well as a description of a number of individuals who valued the incorporation of scientific work in the film theorising process.

Full textAbstract:
The entanglement of conceptual art practices, analytical philosophy and scientific enterprise is a unique provocation — exploring ideas of transference between the visual, the theoretical and the abstract. In this thesis, conducted in the dual modes of empirical (practice-led) and critical research, I aim to unpack these interrelationships — advocating for the recognition of a common, underlying methodological basis that cuts across disciplinary boundaries and activates disparate conceptual concerns. Traversing the historical lineage of conceptual praxis, I present Duchamp’s proto-experimental investigations as the genesis of subsequent conceptual endeavours, leading to the establishment of formal ‘idea art’ in the mid-twentieth century. In addition to an analysis of the visual modalities associated with such practices, I argue that these propositional works draw inevitably on the fields of analytical philosophy, logic, and, ultimately, science itself. In this, I suggest there is a borrowing of formalistic style — a deeply vested structural aesthetic and systematised approach to the development of conceptual works that deploy the mechanics of the ‘experiment’ to engage the viewer in the space of the mind. Such activities pivot irresistibly towards modes of performative action, which amass artefactual documentation as a result of an explicit testing of ideas in the field. These theoretical arguments are buttressed by a sequence of ‘experimental investigations’ — a visual practice developed to consider notions of time and space as measured against a set of self-reflexive metrics. These works were manifest as a set of performative actions that consider questions of interstitial tension that arise near states of disciplinary juncture. Ultimately, the objective of these inquisitions was an assessment of self — to test and in turn be tested in service to preconceived methodological schema.

Resumo: Em virtude da importância das revisões sistemáticas (RSs) como fonte de evidências para a prática na área da saúde, esse tipo de estudo tornou-se cada vez mais frequente. Além disso, requerem pouco recurso financeiro e podem ser realizados em um período menor de tempo quando comparado aos ensaios clínicos. Pesquisadores têm usado esse estudo como uma ferramenta para compilar e avaliar informação útil na tomada de decisões clínicas. Desta forma, facilitar o caminho destas pesquisas para a publicação é essencial uma vez que, um dos meios mais efetivos para a disseminação dos resultados de pesquisas científicas é a apresentação dos mesmos em revistas científicas de alto impacto. Verificar a proporção de revistas científicas da área de Medicina que publicam revisões sistemáticas, bem como, correlacionar seus respectivos fatores de impacto e, identificar se estas revistas solicitam diretrizes específicas para o relato dos achados das revisões sistemáticas. Para cada revista foi averiguado, na seção instruções para autores, a menção do aceite de revisões sistemáticas e exigência das diretrizes específicas de relato das RSs.

Abstract: Due to the importance of systematic reviews as a source of solutions for medical practice, this kind of study has been increasingly more frequent. Furthermore require little financial resources and can be performed in a shorter time compared to the experimental studies. Researchers have used this methodology as a tool to compile and evaluate information useful in making clinical decisions. To determine the proportion and the average impact factor of scientific journals in the field of medicine that publish systematic reviews and require that these works are in accordance with the PRISMA, MOOSE or STARD. We included all 625 scientific journals from 25 medical subspecialties available in Journals Portal Capes, classified areas Medicine I, II and III of Qualis bibliometric evaluator which includes the ISI impact factor. For each issue was examined the systematic review acceptance in the instructions for authors and requirement of target cheklists. When there was no mention of the acceptance, was consulted the content of the scientific journals to know which publish although not mention in instructions for authors. 437 (69,90%) scientific journals published systematic reviews; 135 (21,60%) with acceptance mention in the instructions for authors and 118 (27%) require submission of specific guidelines for reporting of RSs. 302 (48,30%) scientific journal do not mention in the instructions for authors, but publishing and 30,10% (188 journals) do not publish this kind of paper. Only 27% scientific journals require items to be reported in accordance with the specific forms for reporting RSs. The results show the wide acceptance of RSs in the analyzed journals. There is a tendency toward uniformity of editorial policy about publication of RSs and the impact of these scientific journals in the scientific environment. The low-requirement cheklists indicates that editors are not using these tools for evaluating and ...

Full textAbstract:
This thesis is concerned with that branch of the history of science which takes as its central problem the question of scientific progress, defined as the growth of knowledge and understanding about the world. It is an area of enquiry which has been suppressed, in recent years, by the development of historical methodologies which eschew all epistemological deliberations and their established ramifications. This thesis, therefore, addresses itself to the following areas. In Chapter One consideration is given to the degree to which the present ascendancy of contextual, social history of science depends upon formulating methodological strategies that deny the very legitimacy of a progress history of scientific ideas. These strategies are shown to depend upon the old definition of internalist, intellectual history of science. which drew upon related areas in the philosophy of science. Some basic arguments in favour of the possibility of progressive histories of scientific ideas, which have been ignored by the discipline as a whole. are rehearsed. Chapter Two is devoted to an account of how a present-day philosophy of science, aim-oriented empiricism, offers a solution to the problem of induction which, by demonstrating that scientific rationality has a historical dimension, provides a suitable historiographic framework for a progress-oriented history of scientific ideas. Chapter Three examines the work of Galileo in the light of this new historiographic framework.

Full textAbstract:
Fish such as the Leopard Shark (Triakis semifasciata) can be tagged on their fin, released back into the wild, and their location tracked though technologies such as autonomous robots. Timestamped location data about their target is stored. We present a way to procedurally generate an animated simulation of T. semifasciata using only these timestamped location points.
This simulation utilizes several components. Input timestamps dictate a monotonic time-space curve mapping the simulation clock to the space curve. The space curve connects all the location points as a spline without any sharp folds that are too implausible for shark traversal. We create a model leopard shark that has convincing kinematics that respond to the space curve. This is achieved through acquiring a skinned model and applying T. semifasciata motion kinematics that respond to velocity and turn commands. These kinematics affect the spine and all fins that control locomotion and direction. Kinematic- based procedural keyframes added onto a queue interpolate while the shark model traverses the path.
This simulation tool generates animation sequences that can be viewed in real-time. A user study of 27 individuals was deployed to measure the perceived realism of the sequences as judged by the user by contrasting 5 different film sequences. Results of the study show that on average, viewers perceive our simulation as more realistic than not.

Full textAbstract:
This mixed-method study examined the effects of the use of the Vocabulary Think Chart in seventh-grade science students' understanding of scientific vocabulary. Participants included 89 students who attended the only three regular Earth Science classes in the study site. Participants were assigned to the treatment and comparison group according to the teachers' wish on how they wanted to participate in the study. The experimental group received one week long preparation on the use of the Vocabulary Think Chart, followed by five weeks of using the strategy independently. Results of the study did not show a significant change on students' scientific vocabulary understanding and raised questions about vocabulary instruction in science classes. Discussion of the results revolves around the Treatment Teacher's influence in the study, time of intervention, and number of participants.Ph.D.

Full textAbstract:
The United States Army Corp of Engineers relies on accurate and detailed surface models for various construction projects and preventative measures. To aid in these efforts, it is necessary to work for advancements in surface model creation. Current methods for model creation include Delaunay triangulation, raster grid interpolation, and Hydraulic Spline grid generation. While these methods produce adequate surface models, attempts for improved methods can still be made.
A method for raster based spline creation is presented as a variation of the Hydraulic Spline algorithm. By implementing Hydraulic Splines in raster data instead of vector data, the model creation process is streamlined. This method is shown to be more efficient and less computationally expensive than previous methods of surface model creation due to the inherent advantages of raster data over vector data.

Thesis (MTech(Engineering))--Cape Peninsula University of Technology, 2011Reliable analytical results represent the pinnacle assessment of the quality of an analytical laboratory. Variability associated with the analytical method, or process known as selenium analysis which is being used at Western Cape Provincial Veterinary Laboratory (WC PVL), presents a critical quality problem. This is due to the narrow margin of safety between toxic and deficient doses for animal health. In addition, control features of this selenium process, were found to be limited. Limited control features represent ‘process waste’. To overcome the adverse impact of variation and limited control, steps towards process improvement present the best solution.The primary research objective of the research study is: “To establish an alternative accurate and safer digestion procedure within the ‘selenium analysis process, in order to attain quality improvement of the process”.The scientific method was employed to accomplish the research objective. The research design and methodology selected was based on the scientific PDCA cycle, and is known as Lean Six Sigma. A research hypothesis was set as H0 : Variation in process, time and control procedures have a direct impact on the disparity in selenium testing results. Research was able to test the hypothesis using scientific methodology which was empirical, inductive and deductive, systematic, relied on data and was fact based.Implementation of an alternative, more reliable and safer selenium analysis process is believed to result in reduced risks associated to the digestion procedure, while optimising selenium yield and ultimately translating into improved quality in terms of accuracy and precision, thus confidence in results.

Full textAbstract:
The science of behavior analysis relies heavily on direct observation. Human observers are typically used to measure behavior in applied settings. Although the use of human observers is beneficial in many regards, it also presents challenges. Of primary concern is the extent to which the data generated by observers actually corresponds to the behavioral events of interest, and the implications this may have in terms of replication. This study assessed the effects that labels, definitions, and examples and non-examples of two different modalities had on observer accuracy, consistency, and agreement. Results showed that current practices in observer training may require refinement to ensure high observer accuracy, consistency, and agreement. Suggestions for how to improve the desired stimulus control of observers are provided.

Full textAbstract:
This essay examines the argument given by Richard Dawid (2013, 2019) for the viability of non-empirical assessment of scientific theories. Dawid's argument is supposed to show that trust in a scientific theory can be justified without any direct empirical testing of the theory. This view is fundamentally different from what will be called the classical paradigm of theory assessment. The classical paradigm holds that only empirical testing can justify belief in a theory. It is argued in this essay that Dawid's argument does not provide sufficient reasons for claiming that non-empirical assessment can be seen as a valid form of justification of scientific theories. However, it is further argued that non-empirical assessment still can play an important role when evaluating the status of a theory that cannot yet be tested empirically.

Full textAbstract:
This thesis is concerned with the study of biomedical scientific research work that is intensely distributed, i.e. socially distributed across multiple institutions, sites, and disciplines. Specifically, this PhD probes the ways in which scientists co-operating on multi-sited crossdisciplinary projects, design, use and maintain information-based resources to conduct and coordinate their experimental activities. The research focuses on the roles of information artefacts, i.e. the tools, media and devices used to store, track, display, and retrieve information in paper or electronic format, in helping the scientists integrate their activities to achieve concerted action. To examine how scientists in globally distributed settings organise and co-ordinate their scientific work using information artefacts, a multi-method multi-sited study informed by different ethnographic perspectives was conducted focused on a large European crossdisciplinary translational research project in nanodiagnostics. Situated interviews with project scientists, participant observations and participatory learning exercises were designed and deployed. From the data analysis, several abstractions were developed to represent how the joined utilisations of key information artefacts support the co-ordination of experimental activities. Subsequently, a framework was developed to highlight key interactional strategies that need to be managed by experimenters when using artefacts to organise their work cooperatively. This framework was then used as a guiding device to identify innovative ways to design future digital interactive systems to support the co-ordination of intensely distributed scientific work. From this study, several key findings came to light. We identify the role of the experimental protocol acts as a co-ordinative map that is co-designed dynamically to disseminate various instantiations of experimental executions across sites. We have also shed light on the ways the protocol, the lab book and the material log are used jointly to support the articulation of scientific work. The protocol and the lab book are used both locally and across co-operating sites to support four repeatability and reproducibility levels that are key to experimental validation. The use of the local protocol / lab book dyads at each site is further integrated with that of a centralised material log artefact to enable a system of exchange of scientific content (e.g. experimental processes, intermediate results and observations) and experimental materials (both physical materials and key information). We have found that this integration into a co-ordinative cluster supports awareness and the articulation of experimental activities both locally and across remote labs. From this understanding, we have derived several sensitising tensions to frame the strategies that scientific practitioners need to manage when designing their multi-sited experimental work and technologists should consider when designing systems to support them: (1) formalisation / flexibility; (2) articulability / local appropriateness; (3) scrutiny / tinkering; (4) accountability / applicability; (5) traceability / improvisation and (6) lastingness / immediacy. Lastly, based on these tensions, we have suggested a number of implications for the design of interactive information artefacts that can help manage both local and multi-sited co-ordination in intensely distributed scientific projects.

This study attempts to examine evolutionary theory and creationism objectively without engaging in an apology for or a criticism of either. It compares the presuppositions and assumptions of both systems, and examines the role of faith in religion and in the scientific theory of evolution. After discussing the nature of the scientific method and the development of the theory of evolution, the study explores the dichotomy of faith and reason, the ways in which these operate in theories of intelligent design and theistic evolution, and the question of whether scientific evolutionary theory can be considered to be a secular religion. The thesis argues that acceptance of the scientific theory of evolution is as dependent upon a faith commitment as is adherence to religion, though the type and quality of the two respective faith systems are very different and, therefore, worthy of comparison and contrast. The study concludes that, while science and evolutionary theory share many of the same features and characteristics of faith and presumption, it is presently not appropriate to claim that evolutionary theory is a secular religion, and that when this opinion is asserted it is worthwhile to analyze the motivation, conscious and unconscious, involved.Thesis (PhD (Dogmatics))--North-West University, Potchefstroom Campus in association with Greenwich School of Theology, U.K., 2013.

A presente dissertação versa sobre como podemos identificar os Principia, escrito por Newton na sua versão final em 1726, como uma obra estritamente matemática e como podemos identificar a Óptica, 1703, como um livro que parte de experimentos para que fosse formulado. Para tanto apresento primeiramente uma contextualização de época de Newton, para que se apresente as preocupações de Newton na divulgação de suas teorias e então uma leitura estruturada dos Principia que visa explicar como ele é um livro matematicamente estruturado. Após isso apresento a leitura de algumas questões da Óptica visando apresentar como que os experimentos ajudam a compor o livro. Ao final, apresento uma conclusão dividida em três partes, a primeira uma conclusão sobre o método científico de Newton, a segunda uma conclusão que visa dar os últimos argumentos para uma leitura puramente matemática dos Principia e uma terceira que trata por fim sobre os experimentos com a Óptica.
This text is about how We can identify the Principia, writed by Newton in your final version in 1726, as a book strictly math and how We can identify the Optics, 1703, as a book which start from experiments to build on. To do it I show firstly a contextualization of Newton’s time, to show the concerns of Newton about the disclosure of his theories and then a structural read of the Principia to explain how it is mathematically structured. After it, I show a read of few questions from Optics to show how the experiments help to compose the book. In the end, I show a conclusion divided in three parts, the first is a conclusion about scientific method, and the second is to give final arguments to a read of pure math of Principia and, at least, the third that show last arguments to experiments in Optics.

The availability of high performance computing clusters has allowed scientists and engineers to study more challenging problems. However, new algorithms need to be developed to take advantage of the new computer architecture (in particular, distributed memory clusters). Since the solution of linear systems still demands most of the computational effort in many problems (such as the approximation of partial differential equation models) iterative methods and, in particular, efficient preconditioners need to be developed.
In this study, we consider application of incomplete LU (ILU) preconditioners for finite element models to partial differential equations. Since finite elements lead to large, sparse systems, reordering the node numbers can have a substantial influence on the effectiveness of these preconditioners. We study two implementations of the ILU preconditioner: a stucturebased method and a threshold-based method. The main emphasis of the thesis is to test a variety of breadth-first ordering strategies on the convergence properties of the preconditioned systems. These include conventional Cuthill-McKee (CM) and Reverse Cuthill-McKee (RCM) orderings as well as strategies related to the physical distance between nodes and post-processing methods based on relative sizes of associated matrix entries. Although the success of these methods were problem dependent, a number of tendencies emerged from which we could make recommendations. Finally, we perform a preliminary study of the multi-processor case and observe the importance of partitioning quality and the parallel ILU reordering strategy.Master of Science

Resumo: Os tópicos em Mecânica Quântica, ou Física/Química moderna apresentam complexa estrutura conceitual e filosófica. Há que se coordenar imagens contraditórias alpem de se admitir um caráter não determinístico, uma natureza enérgica descontínuo, elementos de probablidade além de postulados. O cenário educacional dos documentos oficiais tais tópicos reflete uma dicotonomia encontrada nas epistemologias das ciências Física e Química. Um olhar sobre a história do Método Científico ainda coloca a Mecânica Quântica como o cerne do fim de uma tradição determinista e o início do que Bachelard denominará de Novo Espírito Científico. Tal Espírito admite pressupostos metafisicos que são encontrados também nos trabalhos de Werner Heinsenberg. O presente trabalho busca então os elementos deste Novo Espírito entre outros elementos da epistemologia de Gaston Bechelard no ideário de licenciados de Física e Química. Como apoio para tal busca torna-se a fenomenologia como metodologia de análise de dados. Esta busca se dá num contexto especialmente construído para tal no que se denomina "atividade pedagógica do não". O presente trabalho constata que tais categorias encontram-se no discurso de licenciandos, todavia, a dialética admitida por Bachelard não é encontrada. Frente a problemas epistêmicos, verifica-se ainda a contradição filosófica, em que a ontologia ora é admitida, ora negada, ocorrendo o mesmo com a epistemologia. O ideário ainda admite múltiplas concepções para um mesmo conceito e obstáculos epistemológicos, assim como conta uma matemática intrincada dentro do processo científico defendido por Bachelard, o que se verifica é uma matemática instrumental fazendo parte de um ferramental que se constitui assim a Mecânica QuânticaAbstract: Quantum Mechanics topics, or Modern Physics / Chemistry topics presents complex philosophical and conceptual framework. It is necessary to coordinate conflictiong images in addition to admiting a non-deterministic character, a discontinuous energetic nature, elements of probability besides postulates. The educational setting of these official documents reflects an epistemological dechotomy that was found in the physics and chemistry sciences. A view of the history of Scientific Method still puts Quantun Mechanics as main reason of the deterministic tradition ending and as the same time the beginning of what is named bu Bachelard as New Scientific Spirit. This Spirit admits methaphysical assumptions that are also found in Werner Heisenberg's work looks for elements of quoted New Spirit among other elements of Gaston Bacherlard's epistemology concerning the ideals of non-graduated Physics and Chemistry students. As support for this research, phenomenology was taken as methodology of data analysis. This research happens into a context particularly made for what is called "pedagogical activity of denial." This current work shows that the referred categories always make part of non-graduated students discourse, and the dialectic admitted by Bachelard doesn't. In front of epistemic issues, there is a philosophical contradiction, where the ontology is admitted and also danied, what exactly happens to epistemology. The mindset still accepts multiple conceptions for the same idea and epistemological obstacles, such as an intricate mathematics in the scientific process supported by Bachelard. As result it is possible to find out an instrumental math making part of tools of what Quantun mechanics is constituted

Functional genetics is the study of the genes present in a genome of an organism, the complex interplay of all genes and their environment being the primary focus of study. The motivation for such studies is the premise that gene expression patterns in a cell are characteristic of its current state. The availability of the entire genome for many organisms now allows scientists unparalleled opportunities to characterize, classify, and manipulate genes or gene networks involved in metabolism, cellular differentiation, development, and disease.
System-wide studies of biological systems have been made possible by the advent of high-throughput and large-scale tools such as microarrays which are capable of measuring the mRNA levels of all genes in a genome. Tools and methods for the integration, visualization, and modeling of the large-scale data obtained in typical systems biology experiments are indispensable. Our work focuses on a method that integrates gene expression values obtained from microarray experiments with biological functional information related to the genes measured in order to make global comparisons of multiple experiments.
In our method, the integrated data is represented as a lattice and, using appropriate measures, a reference experiment can be compared to samples from a database of similar experiments, and a ranking of similarity is returned. In this work, support for the validity of our method is demonstrated both theoretically and empirically: a mathematical description of the lattice structure with respect to the integrated information is developed and the method is applied to data sets of both simulated and reported microarray experiments. A fast algorithm for constructing the lattice representation is also developed.Ph. D.

Full textAbstract:
According to Sterling et al., a batch scheduler, also called workload management, is an application or set of services that provide a method to monitor and manage the flow of work through the system [Sterling01]. The purpose of this research was to develop a method to assess the execution speed of workloads that are submitted to a batch scheduler. While previous research exists, this research is different in that more complex jobs were devised that fully exercised the scheduler with established benchmarks. This research is important because the reduction of latency even if it is miniscule can lead to massive savings of electricity, time, and money over the long term. This is especially important in the era of green computing [Reuther18]. The methodology used to assess these schedulers involved the execution of custom automation scripts. These custom scripts were developed as part of this research to automatically submit custom jobs to the schedulers, take measurements, and record the results. There were multiple experiments conducted throughout the course of the research. These experiments were designed to apply the methodology and assess the execution speed of a small selection of batch schedulers. Due to time constraints, the research was limited to four schedulers. x The measurements that were taken during the experiments were wall time, RAM usage, and CPU usage. These measurements captured the utilization of system resources of each of the schedulers. The custom scripts were executed using, 1, 2, and 4 servers to determine how well a scheduler scales with network growth. The experiments were conducted on local school resources. All hardware was similar and was co-located within the same data-center. While the schedulers that were investigated as part of the experiments are agnostic to whether the system is grid, cluster, or super-computer; the investigation was limited to a cluster architecture.

Full textAbstract:
Das wissenschaftliche Rechnen mit der Computersimulation hat sich heute als dritte Säule der wissenschaftlichen Methodenlehre neben der Theorie und dem Experiment etabliert. Aufgabe der Informatik im wissenschaftlichen Rechnen ist es, sowohl effiziente Simulationsalgorithmen zu entwickeln als auch ihre effiziente Implementierung. Die vorliegende Arbeit richtet ihren Fokus auf die effiziente Implementierung zweier wichtiger Verfahren des wissenschaftlichen Rechnens: die Schnelle Multipolmethode (FMM) für Teilchensimulationen und die Methode der finiten Elemente (FEM), die z. B. zur Berechnung der Deformation von Festkörpern genutzt wird. Die Effizienz der Implementierung bezieht sich hier auf die Ausführungszeit der Simulationen und den zur Ausführung notwendigen Energieverbrauch der eingesetzten Rechnersysteme. Die Steigerung der Effizienz wurde durch modellbasiertes Autotuning erreicht. Beim modellbasierten Autotuning wird für die wesentlichen Teile des Algorithmus ein Modell aufgestellt, das dessen Ausführungszeit bzw. Energieverbrauch beschreibt. Dieses Modell ist abhängig von Eigenschaften des genutzten Rechnersystems, von Eingabedaten und von verschiedenen Parametern des Algorithmus. Die Eigenschaften des Rechnersystems werden durch Ausführung des tatsächlich genutzten Codes für verschiedene Implementierungsvarianten ermittelt. Diese umfassen eine CPU-Implementierung und eine Grafikprozessoren-Implementierung für die FEM und die Implementierung der Nahfeld- und der Fernfeldwechselwirkungsberechnung für die FMM. Anhand der aufgestellten Modelle werden die Kosten der Ausführung für jede Variante vorhergesagt. Die optimalen Algorithmenparameter können somit analytisch bestimmt werden, um die gewünschte Zielgröße, also Ausführungszeit oder Energieverbrauch, zu minimieren. Bei der Ausführung der Simulation werden die effizientesten Implementierungsvarianten entsprechend der Vorhersage genutzt. Während bei der FMM die Performance-Messungen unabhängig von der Ausführung der Simulation durchgeführt werden, wird für die FEM ein Verfahren zur dynamischen Verteilung der Rechenlast zwischen CPU und GPU vorgestellt, das auf Ausführungszeitmessungen zur Laufzeit der Simulation reagiert. Durch Messung der tatsächlichen Ausführungszeiten kann so dynamisch auf sich während der Laufzeit verändernde Verhältnisse reagiert und die Verteilung der Rechenlast entsprechend angepasst werden. Die Ergebnisse dieser Arbeit zeigen, dass modellbasiertes Autotuning es ermöglicht, die Effizienz von Anwendungen des wissenschaftlichen Rechnens in Bezug auf Ausführungszeit und Energieverbrauch zu steigern. Insbesondere die Berücksichtigung des Energieverbrauchs alternativer Ausführungspfade, also die Energieadaptivität, wird in naher Zukunft von großer Bedeutung im wissenschaftlichen Rechnen seinComputer simulation as a part of the scientific computing has established as third pillar in scientific methodology, besides theory and experiment. The task of computer science in the field of scientific computing is the development of efficient simulation algorithms as well as their efficient implementation. The thesis focuses on the efficient implementation of two important methods in scientific computing: the Fast Multipole Method (FMM) for particle simulations, and the Finite Element Method (FEM), which is, e.g., used for deformation problems of solids. The efficiency of the implementation considers the execution time of the simulations and the energy consumption of the computing systems needed for the execution. The method used for increasing the efficiency is model-based autotuning. For model-based autotuning, a model for the substantial parts of the algorithm is set up which estimates the execution time or energy consumption. This model depends on properties of the computer used, of the input data and of parameters of the algorithm. The properties of the computer are determined by executing the real code for different implementation variants. These implementation variantss comprise a CPU and a graphics processor implementation for the FEM, and implementations of near field and far field interaction calculations for the FMM. Using the models, the execution costs for each variant are predicted. Thus, the optimal algorithm parameters can be determined analytically for a minimisation of the desired target value, i.e. execution time or energy consumption. When the simulation is executed, the most efficient implementation variants are used depending on the prediction of the model. While for the FMM the performance measurement takes place independently from the execution of the simulation, for the FEM a method for dynamically distributing the workload to the CPU and the GPU is presented, which takes into account execution times measured at runtime. By measuring the real execution times, it is possible to response to changing conditions and to adapt the distribution of the workload accordingly. The results of the thesis show that model-based autotuning makes it possible to increase the efficiency of applications in scientific computing regarding execution time and energy consumption. Especially, the consideration of the energy consumption of alternative execution paths, i.e. the energy adaptivity, will be of great importance in scientific computing in the near future

Full textAbstract:
The use and application of modeling and simulation (M&S) is pervasive in today's world. A key component in the application of models is to conduct appropriate verification and validation (V&V). V&V is conducted to make sure the model represents reality to the appropriate level of detail based on the questions posed. V&V techniques are well documented within the literature for observable systems, i.e. required data can be collected from the operations of the real system for comparison with the simulation results; however, V&V techniques for non-observable systems are limited to subjective validation. This subjective validation can be applied to the simulation outputs, operational validation, or towards the model development, conceptual validation. Oftentimes subjective operational validation of the simulation is the primary source of validation efforts. It is shown in this thesis that the sole reliance on subjective operational validation of the simulation can easily lead to the inaccurate acceptance of a model. In order to improve M&S practices for the representation of non-observable systems, models must be developed in a methodological manner that provides a traceable and defensible argument behind the model’s representation of reality. Though there is growing discussion within the recent literature, few methods exist on proper conceptual model development and validation. The research objective of this thesis is to identify a methodology to develop a model in a traceable and defensible manner for a system or system of systems that is non-observable. To address this research objective the proposal will address eight aspects of model development. The first is to define a set of terms that are common vernacular in the field of M&S. This is followed by the assessment of what defines a ‘good’ model and how to determine if the model is ‘good’ or not. This leads to a review of V&V and the observation that subjective validation in isolation is not sufficient for model validation. Next, a review of model development procedures is conducted and analyzed against a set of criteria. A selection is made using the Analytic Hierarchy Process (AHP). A procedure developed by Balci in 1986 is selected for the use in development of models for non-observable systems. Specific steps within Balci's 1986 procedure are investigated further to determine appropriate techniques that should be used when developing models of non-observable systems. These steps are system and objective definition, conceptual model, communicative model, and experimental models and results. Five techniques are identified in the literature that can be applied to system and objective definition: Soft Systems Methodology, Requirements Engineering, Unified Modeling Language, Systems Modeling Language, and Department of Defense Architecture Framework. These techniques are reviewed and selection is made using AHP. The System Modeling Language (SysML) is selected as the best technique to perform System an Objective Definition. Significant resources are devoted to the study of conceptual model development. Proposed in this thesis is a process to decompose the impacts of the system and apply subjective weightings in order to identify aspects of the system with significant importance. This approach enables the modeling of the system in question to the appropriate level of fidelity based on the identified importance of the system impacts. Additionally, this process provides traceability and defensibility of the final model form. Communicative model development is rarely addressed in the literature; however, many of the techniques used in system and objective definition can be applied to developing a communicative model. A similar study to the system and objective definition, AHP was utilized to make a selection. It was concluded that the Unified Modeling Language provides the best tool for creating a communicative model. In the final step, experimental models and results, the literature was found to be rich in techniques. A gap was found in the analysis of the outputs of stochastic simulations. Four questions resulted: 'which stochastic measures should be used in analyzing a stochastic simulation?', 'how many replications are required for an accurate estimation of the stochastic measure?', which least squares method should be used in the regression of a stochastic response?, and 'how many replications are required for an accurate regression of a stochastic measure? Heuristics are presented for each of these questions. A proof of concept is provided on the methodology developed within this thesis. The selected scenario is a Humanitarian Aid/Disaster Relief Mission, where the U.S. Navy has been tasked with distributing aid in an effective manner to the affected population. Upon application of the proposed methodology, it was observed that subjective decomposition and weighting of the scenario proved to be a useful tool for guiding and justifying the form of the eventual model. Shortcomings of the methodology were identified. The primary shortcomings identified were the linking of information between the steps of the model development procedure, and the difficulty in correctly identifying the structure of the system impacts decomposition. The primary contribution of this thesis is to the field of M&S. Contributions are made to the practice of conceptual model development, a growing discussion within the literature over the past several years. The contribution to conceptual model development will aid in the development models for non-observable systems. Additional contributions are made to the analysis of stochastic simulations.
The methodology presented in this thesis will provide a new and robust method to develop and validate models in a traceable and defensible manner.

Gender in Medical Careers: Role of Gender in Stereotypes and Research in Doctors’ Professional Lives
Gender relations constitute an important aspect of the contemporary labour market. With rising numbers of women in the work force, they have had to negotiate their gendered identities in the career advancement of their work lives. This thesis seeks to explore the role of gender in medical careers by looking at its impact in two dimensions; on the formation and perpetuation of gender-based stereotypes, and on the role of gender in research activity and scientific productivity. A mixed method approach, employing both qualitative and quantitative research methods, has been used to study the research objectives.
Gender inequality in the form of exclusionary processes and marginalisation mechanisms exist in all the medical specialisations in the composition and decision-making of research teams or collaborations and its subsequent consequences on research activity and scientific productivity. The formation of a research team, research collaboration, marginalisation of women from research groups, restriction of women from performing important research tasks or presence of informal ‘men’s club’ where men support each other’s interests are the invisible exclusionary processes and mechanisms which affect research activity and scientific productivity of male and female doctors. Significant gender differences also exist when it comes to first-authored publications. Additionally, a complex inter-relationship of these outlined issues with a doctor’s job position, specialisation and age can have implications on the scientific productivity of a medical doctor.
Gender roles and gender stereotypes are prevalent in the medical profession where conflicting roles can create tension between hospital personnel. Gender roles are differentiated for men and women in some aspects whereas in other aspects, significant differences between men and women were observed. Gender stereotypes are deeply embedded in a person’s mind-set and many actions, and even the very speech of doctors, show that sexist attitudes have been internalised by doctors and nurses. Female doctors consider themselves ‘lucky’ and rarely credit their own hard work for their successes or achievements. Female doctors try to ‘become like men’ in order to be successful in their careers. It is interesting that understanding and compassion, which are seen as traditionally feminine traits or ‘communal’ traits, are displayed by both men and women and not by women alone in the medical profession. Decisiveness and assertiveness, traditionally ‘masculine’ traits, are displayed more by men than women for low to medium levels of the traits. However, women exhibiting ‘masculine’ traits such as ambitiousness or aggressiveness may be judged harshly. It is not just gender, but a cross-section of age and gender too that affects stereotypes and relationships between doctors, in the doctor-nurse or doctor-patient relationship in the hospital work space.

A necessidade de obter solução de grandes sistemas lineares resultantes de processos de discretização de equações diferenciais parciais provenientes da modelagem de diferentes fenômenos físicos conduz à busca de técnicas numéricas escaláveis. Métodos multigrid são classificados como algoritmos escaláveis.Um estimador de erros deve estar associado à solução numérica do problema discreto de modo a propiciar a adequada avaliação da solução obtida pelo processo de aproximação. Nesse contexto, a presente tese caracteriza-se pela proposta de reutilização das estruturas matriciais hierárquicas de operadores de transferência e restrição dos métodos multigrid algébricos para acelerar o tempo de solução dos sistemas lineares associados à equação do transporte de contaminantes em meio poroso saturado. Adicionalmente, caracteriza-se pela implementação das estimativas residuais para os problemas que envolvem dados constantes ou não constantes, os regimes de pequena ou grande advecção e pela proposta de utilização das estimativas residuais associadas ao termo de fonte e à condição inicial para construir procedimentos adaptativos para os dados do problema. O desenvolvimento dos códigos do método de elementos finitos, do estimador residual e dos procedimentos adaptativos foram baseados no projeto FEniCS, utilizando a linguagem de programação PYTHONR e desenvolvidos na plataforma Eclipse. A implementação dos métodos multigrid algébricos com reutilização considera a biblioteca PyAMG. Baseado na reutilização das estruturas hierárquicas, os métodos multigrid com reutilização com parâmetro fixo e automática são propostos, e esses conceitos são estendidos para os métodos iterativos não-estacionários tais como GMRES e BICGSTAB. Os resultados numéricos mostraram que o estimador residual captura o comportamento do erro real da solução numérica, e fornece algoritmos adaptativos para os dados cuja malha retornada produz uma solução numérica similar à uma malha uniforme com mais elementos. Adicionalmente, os métodos com reutilização são mais rápidos que os métodos que não empregam o processo de reutilização de estruturas. Além disso, a eficiência dos métodos com reutilização também pode ser observada na solução do problema auxiliar, o qual é necessário para obtenção das estimativas residuais para o regime de grande advecção. Esses resultados englobam tanto os métodos multigrid algébricos do tipo SA quanto os métodos pré-condicionados por métodos multigrid algébrico SA, e envolvem o transporte de contaminantes em regime de pequena e grande advecção, malhas estruturadas e não estruturadas, problemas bidimensionais, problemas tridimensionais e domínios com diferentes escalas.The need for solving large linear systems arising from the discretization of partial differential equations modelling physical phenomena motivates the search for scalable numerical techniques. Multigrid algorithms are instances of such techniques.In order to provide a suitable assessment of the solution obtained by such algorithms, an error estimator must be associated to the numerical solution of the discretized problem. In this context, this thesis proposes the reutilization of the hierarchical matrix structures of transfer operators and the restriction to algebraic multigrid methods to speed up the process of solving the linear systems associated with the contaminant transport equation in saturated porous media. In addition, it features the implementation of residual estimates for problems involving constant or non-constant data, the regimes of small- or large-scale advection and the proposal of employing the residual estimates associated to the source term and to the initial condition to build adaptive procedures for the problem data. The development of the computer codes of the finite element method, residual estimator and adaptive procedures were based on the FEniCS project, using the programming language PYTHONR and developed on the Eclipse platform. The implementation of the algebraic methods with reutilization relied upon the libray PyAMG. Grounding on the idea of reutilizing the hierarchical structures, fixed and automatic parameters multigrid methods were proposed and extended to non-stationary iterative methods such as GMRES and BICGSTAB. The numerical results demonstrate that the residual estimator captures the behavior of the real error of the numerical solution, and provide adaptive algorithms for the data whose output mesh yields a numerical solution alike to that obtained from a uniform mesh with more elements. Moreover, the methods with reutilization are faster than those that do not reuse the structures. Besides, the efficiency of such methods can also be observed in the solution of an auxiliary problem, which is necessary for deriving the residual estimates in the regime of large-scale advection. These results encompass both the type SA algebraic multigrid method and those pre-conditioned by them. Moreover, they involve the transport of contaminants in regime of small- and large-scale advection, structured and non-structured meshes, bi- and tridimensional problems and domains with different scales.

Due to the importance of systematic reviews as a source of solutions for medical practice, this kind of study has been increasingly more frequent. Furthermore require little financial resources and can be performed in a shorter time compared to the experimental studies. Researchers have used this methodology as a tool to compile and evaluate information useful in making clinical decisions. To determine the proportion and the average impact factor of scientific journals in the field of medicine that publish systematic reviews and require that these works are in accordance with the PRISMA, MOOSE or STARD. We included all 625 scientific journals from 25 medical subspecialties available in Journals Portal Capes, classified areas Medicine I, II and III of Qualis bibliometric evaluator which includes the ISI impact factor. For each issue was examined the systematic review acceptance in the instructions for authors and requirement of target cheklists. When there was no mention of the acceptance, was consulted the content of the scientific journals to know which publish although not mention in instructions for authors. 437 (69,90%) scientific journals published systematic reviews; 135 (21,60%) with acceptance mention in the instructions for authors and 118 (27%) require submission of specific guidelines for reporting of RSs. 302 (48,30%) scientific journal do not mention in the instructions for authors, but publishing and 30,10% (188 journals) do not publish this kind of paper. Only 27% scientific journals require items to be reported in accordance with the specific forms for reporting RSs. The results show the wide acceptance of RSs in the analyzed journals. There is a tendency toward uniformity of editorial policy about publication of RSs and the impact of these scientific journals in the scientific environment. The low-requirement cheklists indicates that editors are not using these tools for evaluating and ...

Há que se coordenar imagens contraditórias alpem de se admitir um caráter não determinístico, uma natureza enérgica descontínuo, elementos de probablidade além de postulados. O cenário educacional dos documentos oficiais tais tópicos reflete uma dicotonomia encontrada nas epistemologias das ciências Física e Química. Um olhar sobre a história do Método Científico ainda coloca a Mecânica Quântica como o cerne do fim de uma tradição determinista e o início do que Bachelard denominará de Novo Espírito Científico. Tal Espírito admite pressupostos metafisicos que são encontrados também nos trabalhos de Werner Heinsenberg. O presente trabalho busca então os elementos deste Novo Espírito entre outros elementos da epistemologia de Gaston Bechelard no ideário de licenciados de Física e Química. Como apoio para tal busca torna-se a fenomenologia como metodologia de análise de dados. Esta busca se dá num contexto especialmente construído para tal no que se denomina atividade pedagógica do não. O presente trabalho constata que tais categorias encontram-se no discurso de licenciandos, todavia, a dialética admitida por Bachelard não é encontrada. Frente a problemas epistêmicos, verifica-se ainda a contradição filosófica, em que a ontologia ora é admitida, ora negada, ocorrendo o mesmo com a epistemologia. O ideário ainda admite múltiplas concepções para um mesmo conceito e obstáculos epistemológicos, assim como conta uma matemática intrincada dentro do processo científico defendido por Bachelard, o que se verifica é uma matemática instrumental fazendo parte de um ferramental que se constitui assim a Mecânica Quântica
Quantum Mechanics topics, or Modern Physics / Chemistry topics presents complex philosophical and conceptual framework. It is necessary to coordinate conflictiong images in addition to admiting a non-deterministic character, a discontinuous energetic nature, elements of probability besides postulates. The educational setting of these official documents reflects an epistemological dechotomy that was found in the physics and chemistry sciences. A view of the history of Scientific Method still puts Quantun Mechanics as main reason of the deterministic tradition ending and as the same time the beginning of what is named bu Bachelard as New Scientific Spirit. This Spirit admits methaphysical assumptions that are also found in Werner Heisenberg's work looks for elements of quoted New Spirit among other elements of Gaston Bacherlard's epistemology concerning the ideals of non-graduated Physics and Chemistry students. As support for this research, phenomenology was taken as methodology of data analysis. This research happens into a context particularly made for what is called pedagogical activity of denial. This current work shows that the referred categories always make part of non-graduated students discourse, and the dialectic admitted by Bachelard doesn't. In front of epistemic issues, there is a philosophical contradiction, where the ontology is admitted and also danied, what exactly happens to epistemology. The mindset still accepts multiple conceptions for the same idea and epistemological obstacles, such as an intricate mathematics in the scientific process supported by Bachelard. As result it is possible to find out an instrumental math making part of tools of what Quantun mechanics is constituted

This research addresses the historical development of the experimental physiology of Claude Bernard (1813-1878) by focusing on the continuities and discontinuities of his thought through the analysis of a manuscript entitled Philosophie, a compilation of reflections on a course on philosophy. It was possible to temporally and epistemologically distinguish two phases in this demarche. The first one corresponds to the years under the influence of François Magendie, thus comprising Bernard´s medical education and early research work. The second one begins by the time Bernard was recovering from a disease and whose first product was Introduction to the Study of Experimental Medicine, published in 1865. Analysis of Philosophie allowed identifying reflections significant to Bernard´s construction of the grounds of experimental science, leading to his founding concept, namely determinism. Similarly, it shows important differences between Bernard´s and Auguste Comte´s thought
Este trabalho mostra, no tempo histórico, o desenvolvimento da fisiologia experimental de Claude Bernard, abordando as continuidades e descontinuidades em sua obra, através da análise do manuscrito Philosophie, uma coletânea de reflexões do autor sobre um curso de filosofia. Foi possível localizar, temporal e epistemologicamente, o pensamento de Bernard em duas fases diferentes. A primeira corresponde a um período magendiano , abrangendo sua formação e seus primeiros trabalhos; a segunda, que se inicia por ocasião da convalescença de Bernard, e que se expressa através da publicação, em 1865, de Introdução ao Estudo da Medicina Experimental. A análise da obra Philosophie permitiu identificar reflexões importantes de Bernard sobre as bases ciência experimental, o determinismo e as diferenças entre seu pensamento e aquele de Auguste Comte

A presente Tese compreende uma análise de três componentes estreitamente relacionados do pensamento de Pierre Duhem (1861-1916), a saber, a historiografia da ciência, a filosofia da história e o método histórico. Na primeira parte, examinamos as relações essenciais estabelecidas entre o método histórico e a filosofia da história duhemianas. Na segunda, nossa atenção volta-se para o estudo de alguns aspectos da historiografia de nosso autor que têm sido negligenciados pela literatura secundária, em especial, a sua concepção das revoluções científicas. Acreditamos ser possível compor uma interpretação sintética que harmonize, sem incoerências, as afirmações que conduzem os comentadores a vê-lo como um continuísta estrito e, por outro lado, algumas passagens esquecidas que tendem a reforçar uma interpretação descontinuísta.The present Thesis encompasses an analysis of three closely related components of Pierre Duhems thought, namely, the historiography of science, the philosophy of history and the historical method. In the first part, we examine the essential relationships established between the Duhemian historical method and his philosophy of history. In the second part, our attention turns to the study of some aspects of Duhems historiography that have been neglected by the secondary literature, particularly, the Duhemian conception of scientific revolutions. We believe that it is possible to compose a synthetic interpretation that harmonizes, without inconsistencies, on the one hand, the assertions of the French historian that led the commentators to see him as a strict continuist and, on the other hand, some other forgotten passages that tend to reinforce a discontinuist interpretation.

The subject of this study is the effects of two types of teaching instruction: traditional and experimental teaching instructions based on the active teaching of physics. In this article is presented the problem solving teaching and the scientific method as a teaching instruction in active teaching of physics. - 232 -Scientific method that is the subject of this research is based on simple experiments in physics that do not require expensive equipment and can be implemented with minimum teaching resources that are available to every student. There are presented results of research carried out to study the effect of the applied educational instruction in physics, the result of the overall educational performance, durability of acquired knowledge and understanding of aspects of the nature of science and scientific research in relation to the traditional teaching. The study was conducted as a pedagogical experiment of parallel groups in a sample of sixth and eighth-graders, in schools "Miroslav Antic" and "Desanka Maksimovic" in Futog. The study of pedagogical documentation as well as the results obtained from initial test designed for the purpose of this research, formed the control and experimental groups matched for relevant educational parameters. Is done a comparison of the control group – the problem teaching, the control group - the scientific method and the problem teaching - the scientific method, in quantum, quality and efficiency of knowledge of the applied methods. The results were statistically analyzed. There existed significant differences in the durability of knowledge retention, faster and more thorough adoption of educational content using of the active teaching instruction in teaching physics than traditional teaching. Analysis of the results of the final test shows a positive trend understanding of almost all aspects of the nature of science in the experimental groups. The main drawback in the implementation of the teaching instruction students is individual differences in the speed of solving the problem, and the lack of adequate literature to support this form of teaching.
