Texte intégralHorseracing and its associated activity of gambling invites academic research of a multidisciplinary nature. Economics, psychology, mathematics and statistics are all fields that have investigated the two topics. In 1976 economists discovered a new body of data on which they could test their theories. For many years psychologists have investigated human behaviour in gambling situations. Mathematicians have developed optimal betting strategies. Statisticians have assisted in all the investigations as well as utilised decision theory, probability theory and regression analysis, in their own right, within the discipline. Why do academics devote their time to this subject? The furthering of knowledge in general in the above fields is important. Also, because the possibility of making money with relatively little work exists, people from all walks of life will be drawn to the intellectual challenge of finding winners. Researchers know that in order to derive money making systems, research on an academic scale is necessary. The amount of data available is phenomenal and although much of it is utilized by the public, some of it is not and that which is, is not always used in a consistent manner. The research in this work concentrates on all four fields mentioned above. A general, overview of the work done in each section is as follows. In chapters two and three, the betting market is examined within the framework of the efficient markets hypothesis. Tests of the three well known forms of efficiency are performed. In chapter four, within the framework of the expected utility hypothesis, the behaviour of gamblers is analysed. The investigation concentrates on behaviour observed at the racetrack, but draws ideas from other gambling situations as well. In chapter five, an investigation is made into horseraces, considering a race to be a sports event. This will consider the competing horses as athletes and will try and identify which fundamental factors are most important in determining the victor of such a race. In chapter six, some statistical theory, which has simple applications in horseracing is examined. In chapter seven, the economics of racetrack management is investigated.

Texte intégralMargot O'Toole, Imanishi-Kari's postdoctoral fellow at the time, was unable to reproduce some of the experimental results published in the paper and could not resolve this with her postdoctoral supervisor. Subsequently, O'Toole became convinced that there were serious errors in the paper and, shortly afterwards, the National Institutes of Health began officially investigating the questions she raised about it.
It may have been simply a character clash between Imanishi-Kari and O'Toole but partly due to the involvement of a figure such as Baltimore, this clash possibly ruined their careers, took 10 years to settle down, cost millions of dollars of public money, polarized the scientific community, and went down in history as one of the most widely followed cases of scientific fraud.
Based on statistical, forensic and other evidence, Imanishi-Kari was found guilty of scientific misconduct and banned from receiving public funding for 10 years. This was not the end of the matter, however, because Imanishi-Kari appealed the decision and was later exonerated.
In this thesis, we tell the statistical story by putting forward the statistical arguments that were used against Imanishi-Kari and the counterarguments to them.

Doctoral thesis, Norwegian University of Science and Technology, Faculty of Information Technology, Mathematics and Electrical Engineering, 2008. http://urn.kb.se/resolve?urn=urn:nbn:no:ntnu:diva-2191.
Texte intégralScientific Computing is the collection of tools, techniques, and theories required to solve on a computer, mathematical models of problems from science and engineering, and its main goal is to gain insight in such problems. Generally, it is difficult to understand or communicate information from complex or large datasets generated by Scientific Computing methods and techniques (computational simulations, complex experiments, observational instruments etc.). Therefore, support of Scientific Visualization is needed, to provide the techniques, algorithms, and software tools needed to extract and display appropriately important information from numerical data.
Usually, complex computational and visualization algorithms require large amounts of computational power. The computing power of a single desktop computer is insufficient for running such complex algorithms, and, traditionally, large parallel supercomputers or dedicated clusters were used for this job. However, very high initial investments and maintenance costs limit the availability of such systems. A more convenient solution, which is becoming more and more popular, is based on the use of nondedicated desktop PCs in a Desktop Grid Computing environment. Harnessing idle CPU cycles, storage space and other resources of networked computers to work together on a particularly computational intensive application does this. Increasing power and communication bandwidth of desktop computers provides for this solution.
In a desktop grid system, the execution of an application is orchestrated by a central scheduler node, which distributes the tasks amongst the worker nodes and awaits workers’ results. An application only finishes when all tasks have been completed. The attractiveness of exploiting desktop grids is further reinforced by the fact that costs are highly distributed: every volunteer supports her resources (hardware, power costs and internet connections) while the benefited entity provides management infrastructures, namely network bandwidth, servers and management services, receiving in exchange a massive and otherwise unaffordable computing power. The usefulness of desktop grid computing is not limited to major high throughput public computing projects. Many institutions, ranging from academics to enterprises, hold vast number of desktop machines and could benefit from exploiting the idle cycles of their local machines.
In the work presented in this thesis, the central idea has been to provide a desktop grid computing framework and to prove its viability by testing it in some Scientific Computing and Visualization experiments. We present here QADPZ, an open source system for desktop grid computing that have been developed to meet the above presented needs. QADPZ enables users from a local network or Internet to share their resources. It is a multi-platform, heterogeneous system, where different computing resources from inside an organization can be used. It can be used also for volunteer computing, where the communication infrastructure is the Internet. QADPZ supports the following native operating systems: Linux, Windows, MacOS and Unix variants. The reason behind natively supporting multiple operating systems, and not only one (Unix or Windows, as other systems do), is that often, in real life, this kind of limitation restricts very much the usability of desktop grid computing.
QADPZ provides a flexible object-oriented software framework that makes it easy for programmers to write various applications, and for researchers to address issues such as adaptive parallelism, fault-tolerance, and scalability. The framework supports also the execution of legacy applications, which for different reasons could not be rewritten, and that makes it suitable for other domains as business. It also supports low-level programming languages as C/C++ or high-level language applications, (e.g. Lisp, Python, and Java), and provides the necessary mechanisms to use such applications in a computation. Consequently, users with various backgrounds can benefit from using QADPZ. The flexible object-oriented structure and the modularity allow facile improvements and further extensions to other programming languages.
We have developed a general-purpose runtime and an API to support new kinds of high performance computing applications, and therefore to benefit from the advantages offered by desktop grid computing. This API directly supports the C/C++ programming language. We have shown how distributed computing extends beyond the master-worker paradigm (typical for such systems) and provided QADPZ with an extended API that supports in addition lightweight tasks and parallel computing (using the message passing paradigm - MPI). This extends the range of applications that can be used to already existing MPI based applications - e.g. parallel numerical solvers used in computational science, or parallel visualization algorithms.
Another restriction of existing systems, especially middleware based, is that each resource provider needs to install a runtime module with administrator privileges. This poses some issues regarding data integrity and accessibility on providers computers. The QADPZ system tries to overcome this by allowing the middleware module to run as a non-privileged user, even with restricted access, to the local system.
QADPZ provides also low-level optimizations, such as on-the-fly compression and encryption for communication. The user can choose from different algorithms, depending on the application, improving both the communication overhead imposed by large data transfers and keeping privacy of the data. The system goes further, by providing an experimental, adaptive compression algorithm, which can transparently choose different algorithms to improve the application. QADPZ support two different protocols (UDP and TCP/IP) in order to improve the efficiency of communication.
Free source code allows its flexible installations and modifications based on the particular needs of research projects and institutions. In addition to being a very powerful tool for computationally intensive research, the open sourceness makes QADPZ a flexible educational platform for numerous smallsize student projects in the areas of operating systems, distributed systems, mobile agents, parallel algorithms, etc. Open source software is a natural choice for modern research as well, because it encourages effectively integration, cooperation and boosting of new ideas.
This thesis proposes also an improved conceptual model (based on the master-worker paradigm), which makes contributions in several directions: pull vs. push work-units, pipelining of work-units, more work-units sent at a time, adaptive number of workers, adaptive time-out interval for work-units, and multithreading. We have also demonstrated that the use of desktop grids should not be limited to only master-worker applications, but it can be used for more fine-grained parallel Scientific Computing and Visualization applications, by performing some specific experiments. This thesis makes supplementary contributions: a hierarchical taxonomy of the main existing desktop grids, and an adaptive compression algorithm for remote visualization. QADPZ has also pioneered autonomic computing approach for desktop grids and presents specific self-management features: self-knowledge, self-configuration, selfoptimization and self-healing. It is worth to mention that to the present the QADPZ has over a thousand users who have download it (since July, 2001 when it has been uploaded to sourceforge.net), and many of them use it for their daily tasks (see the appendix). Many of the results have been published or are in course of publishing as it can be seen from the references.
Megler, Veronika Margaret. « Ranked Similarity Search of Scientific Datasets| An Information Retrieval Approach ». Thesis, Portland State University, 2014. http://pqdtopen.proquest.com/#viewpdf?dispub=3629331.
Texte intégralIn the past decade, the amount of scientific data collected and generated by scientists has grown dramatically. This growth has intensified an existing problem: in large archives consisting of datasets stored in many files, formats and locations, how can scientists find data relevant to their research interests? We approach this problem in a new way: by adapting Information Retrieval techniques, developed for searching text documents, into the world of (primarily numeric) scientific data. We propose an approach that uses a blend of automated and curated methods to extract metadata from large repositories of scientific data. We then perform searches over this metadata, returning results ranked by similarity to the search criteria. We present a model of this approach, and describe a specific implementation thereof performed at an ocean-observatory data archive and now running in production. Our prototype implements scanners that extract metadata from datasets that contain different kinds of environmental observations, and a search engine with a candidate similarity measure for comparing a set of search terms to the extracted metadata. We evaluate the utility of the prototype by performing two user studies; these studies show that the approach resonates with users, and that our proposed similarity measure performs well when analyzed using standard Information Retrieval evaluation methods. We performed performance tests to explore how continued archive growth will affect our goal of interactive response, developed and applied techniques that mitigate the effects of that growth, and show that the techniques are effective. Lastly, we describe some of the research needed to extend this initial work into a true “Google for data”.

Texte intégralGillrell, C. Scientific approach in clinical placement in nursing education. A phenomenographic study. Degree project in Care Science 15 credits. Malmö University: Faculty of health and society, Department of Care Science, 2015.It is a challenge for nursing students to identify the care needs of a patient. Current study has focused what the supervising nurse perceived to be the center of a scientific approach in nursing and how the phenomenon was communicated to the nursing students. The results showed variation in the purpose of a scientific approach. Some supervisors perceived that the purpose of the phenomenon was to identify care needs, others meant that the aim was to carry out nursing flexible based on factual knowledge and what was best for the patient. The strongest support for the goal of a scientific approach in nursing work was to provide the best and safest care for a specific patient. The phenomenon of scientific approach could be communicated, in the clinical placement, if given the time and space, and if the student had structured learning activities and reflection in action, and on action.

Texte intégralO conhecimento é o centro de operação das organizações, na atualidade. Este entendimento leva as organizações a reconhecerem explicitamente que o seu capital intelectual é fonte essencial de vantagem competitiva. A tendência atual é a de integração da organização, o que cria a necessidade de entendê-la como um todo sistêmico, implementando os novos conceitos e abordagens de forma adaptativa à realidade organizacional. A gestão do conhecimento, nessa nova abordagem, incorpora todos esses aspectos, tornando-se uma tarefa complexa que deve ser amplamente estudada para ser inserida na rotina da organização. Neste trabalho são abordados os comitês técnico-científicos, um instrumento julgado capaz de contribuir para a criação de um contexto de facilitação das atividades em grupo em organizações complexas de ensino e/ou pesquisa, tal como o Centro Técnico Aeroespacial, aqui tomado como estudo de caso. Diversos fatores organizacionais, culturais e comportamentais influenciam a implantação desse instrumento gerencial e necessitam ser analisados, a fim de se ter uma sistemática de implantação que tenha êxito. O objetivo da pesquisa foi a identificação de aspectos favoráveis e desfavoráveis à implantação dos comitês técnico-científicos no Centro. Esses fatores não devem ser considerados isoladamente. Para o sucesso da implantação dos comitês, o inter-relacionamento desses fatores deve ser analisado, contemplando uma visão sistêmica da organização. Pôde-se verificar também, nesta pesquisa, que os comitês são considerados importantes para as atividades do Centro Técnico Aeroespacial.

Texte intégralFue a partir de la publicación científica de la EFSA “Opinión científica sobre el riesgo existente para animales y la salud pública en relación a la presencia de toxinas de Alternaria en productos alimentarios y piensos” que surgió la idea de desarrollar esta Tesis Doctoral. En primer lugar, se escogieron dos industrias alimentarias de la provincia de Lleida y se inició la recolecta de muestres de tomate durante dos campañas con el objetivo de determinar la presencia de especies viables de Alternaria mediante la técnica PMA-qPCR y, a su vez, se analizó la presencia de dos micotoxinas de Alternaria (AOH y AME). En segundo lugar, se estudiaron dos componentes de la familia de proteínas Velvet (VeA y LaeA) y, paralelamente, se indagó en el metabolismo de les poliaminas en Alternaria alternata con el objetivo de encontrar nuevas diana útiles para el diseño de nuevos fungicidas. El segundo lugar, se analizaron los efectos del 1-metilciclopropeno en A. alternata infectando tomates en relación al crecimiento fúngico y a la producción de AOH y AME. Finalmente, se estudió la estabilidad de AOH y AME durante el proceso industrial de productos derivados de tomate
As a result of the publication of the EFSA’S scientific report, entitled “Scientific opinion on the risks for animal and public health related to the presence of Alternaria toxins in feed and food”, arose the idea of developing this Doctoral Thesis. The first steps were to assess the presence of viable Alternaria spp. using the PMA-qPCR technique and, additionally, analyze the occurrence of two Alternaria mycotoxins (AOH and AME). A second approach to the problem was to focus the study in analyzing two components of the Velvet family (VeA and LaeA) and, at the same time, the polyamine metabolism in order to find new targets useful to design new fungicides. Secondly, in a postharvest context, effects of 1-methylcyclopropene were analyzed on A. alternata infecting tomatoes in relation to fungal growth and mycotoxin production. Finally, the stability of AOH and AME along the industrial process of tomato derivate products was studied

Texte intégralReliable 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.
