Testo completoAbstract (sommario):
Interest in more accurate assignment of overhead costs to establish credible product/service cost profiles has assumed substantial prominence in much of the recent debates on management accounting practices. While the promotion of new cost management systems and in particular Activity Based Costing (ABC) has promised to address many of the perceived shortcomings of more traditional and long established techniques, the lack of its implementation success raises some concern as to the validity and value of these new system designs. A major purpose of this thesis is the development of a mathematical model that is capable of computing overhead allocations on the basis of organisational specific dimensions other than DLH.While almost all data bases suffer from data entry and omission errors, the information content contained in the data bases often forms the basis for management decisions without first confirming the accuracy of the data base content. The model has been successfully applied and tested to detect internal consistency and data element detail accuracy. Future research may test the applicability of the model with more diverse data bases to confirm its generalisability as an investigative as well as predictive model.Doctor of Philosophy (PhD)

O progresso de projetos anteriores salientou a necessidade de tratar o problema dos softwares para detecção, a partir de bases de dados de publicações científicas, de tendências emergentes de pesquisa e desenvolvimento. Evidenciou-se a carência de aplicações computacionais eficientes dedicadas a este propósito, que são artigos de grande utilidade para um melhor planejamento de programas de pesquisa e desenvolvimento em instituições. Foi realizada, então, uma revisão dos softwares atualmente disponíveis, para poder-se delinear claramente a oportunidade de desenvolver novas ferramentas. Como resultado, implementou-se um aplicativo chamado Citesnake, projetado especialmente para auxiliar a detecção e o estudo de tendências emergentes a partir da análise de redes de vários tipos, extraídas das bases de dados científicas. Através desta ferramenta computacional robusta e eficaz, foram conduzidas análises de frentes emergentes de pesquisa e desenvolvimento na área de Sistemas Geradores de Energia Nuclear de Geração IV, de forma que se pudesse evidenciar, dentre os tipos de reatores selecionados como os mais promissores pelo GIF - Generation IV International Forum, aqueles que mais se desenvolveram nos últimos dez anos e que se apresentam, atualmente, como os mais capazes de cumprir as promessas realizadas sobre os seus conceitos inovadores.

Includes bibliographical references.Evaluating the performance of organisations is essential to good planning and control. Part of this process is monitoring the performance of organisations against their goals. The comparative efficiency of organizations using common inputs and outputs makes it possible for organizations to improve their performance so that can operate as the most efficient organizations. Resources and outputs can be very diversified in nature and it is complex to assess organizations using such resources and outputs. Data Envelopment Analysis models are designed to facilitate this of assessment and aim to evaluate the relative efficiency of organisations. Chapter 2 is dedicated to the basic Data Envelopment Analysis. We present the following: * A review of the Data Envelopment Analysis models; * The properties and particularities of each model. In chapter 3, we present our literature survey on restrictions. Data Envelopment Analysis is a value-free frontier which has the of yielding more objective efficiency measures. However, the complete freedom in the determination of weights for the factors and products) relevant to the assessment of organisations has led to some problems such as: zero-weights and lack of discrimination between efficient organizations. Weight restriction methods were introduced in order to tackle these problems. The first part of chapter 3 in detail the motivations for weight restrictions while the second part presents the actual weight restriction rnethods.

Shi, H. (Henglin). "A GQM-based open research data technology evalution method in open research context". Master's thesis, University of Oulu, 2016. http://urn.fi/URN:NBN:fi:oulu-201605221853.
Testo completoAbstract (sommario):
Open Research Data is gaining popularity nowadays, and various research units and individuals are interested to join this trend. However, due to variety of Open Research Data technologies, they have found it is difficult to select proper ones for their specific requirements. Thus, a method for evaluating of Open Research Data related technologies is developed in this study for researchers to select proper ones.
Firstly, the theoretical knowledge of research data sharing and reusing barriers is resulted from a structured literature review. As a result, from the 19 primary studies, 96 instances of existing barriers are identified and classified to seven categories, where four of them are research data sharing barriers and rest of them are reusing barriers. This knowledge is regarded as an important resource for understanding researchers’ requirements on Open Research Data technologies, and utilized to develop the technology evaluation method.
Additionally, the Open Research Data Technology Evaluation Method (ORDTEM) is developed basing on the Goal/Question/Metric (GQM) approach and resulted research data sharing and reusing barriers. To develop this method, the GQM approach is adopted as the main skeleton to transform these barriers to measurable criterion. Consequently, the ORDTEM, which is consisting of six GQM evaluation questions and 14 metrics, is developed for researchers to evaluate Open Research Data technologies.
Furthermore, to validate the GQM-based ORDTEM, a focus groups study is conducted in a workshop. In the workshop, nine researchers who has the need to participate Open Research Data related activities are recruited to form a focus group to discuss the resulted ORDTEM. And by analysing the content of the discussion, 16 critical opinions are addressed which resulted eight improvements including one refinement on an existing metric and seven new metrics to ORDTEM.
Lastly, a testing process of applying ORDTEM to evaluate four selected Open Research Data technologies is implemented also for validating whether it can be used in solving real-world evaluation tasks. And more than the validation, this experiment also results the materials about usage of ORDTEM, which is useful for future adopters.
However, more than developing the solution to eliminate the difficulty of selecting technologies for participating Open Research Data movements, this study also provides two additional contributions. For one thing, resulted research data sharing and reusing barriers also direct the future effort to prompt Open Research Data and Open Science. Moreover, the experience of utilizing the GQM approach to transform existing requirements to evaluation criterion is possible to be studied for developing other requirement-specific evaluation.

Testo completoAbstract (sommario):
Advances and integration of information and communication technologies into healthcare systems offer new opportunities to improve public health worldwide. In Sweden, there are already unique possibilities for epidemiological research from registers because of a long tradition of centralized data collection into population-based registers and their allowance for linkage. The growing efficiency of automated digital storage provides growing volumes of archived data that increases the potential of analyses further. The purpose of this thesis can be divided into two parallel themes: illustrations and discussions of the use and usefulness of population-based registers on the one hand, and specific research questions in epidemiology and healthcare research on the other. The research questions are addressed in separate papers. From the Swedish Cancer Registry, 25 years of incidence data on testicular cancer was extracted for a large cohort. Record linkage to survey data on serum cholesterol showed a highly significant positive association, suggesting that elevated serum cholesterol concentration is a risk factor for testicular cancer. Since the finding is the first of its kind and because of wide confidence intervals further studies are needed to confirm the association. Östergötland County council’s administra-tive database (the Care Data Warehouse in Östergötland (CDWÖ)) provided data for preva-lence estimations of four common chronic diseases. The prevalence rate agreed very well with previous estimates for diabetes and fairly well with those for asthma. For hypertension and chronic obstructive pulmonary disease, the observed rates were lower than previous prevalence estimates. Data on several consecutive years covering all healthcare levels are needed to achieve valid prevalence estimates. CDWÖ data was also used to analyse the impact of diabetes on the prevalence of ischemic heart disease. Women had higher diabetes/non-diabetes prevalence rate ratios across all ages. The relative gender difference remained up to the age of 65 years and thereafter decreased considerably. The age-specific direct healthcare cost of diabetes was explored using data from the CDWÖ, the county council’s Cost Per Patient database and the Swedish Prescribed Drug Register. The cost per patient and the relative magnitude of different cost components varied considerably by age, which is important to consider in the future planning of diabetes management. The Cancer Registry was established mainly as a basis for epidemiological surveillance and research, exemplified in this thesis by a study on testicular cancer. In contrast, the newly established and planned healthcare databases in different Swedish counties are mainly for managerial purposes. As is shown in this thesis, these new databases may also be used to address problems in epidemiology and healthcare research.

Includes bibliographical references (pages 141-145).
In the design and operation of urban mobility systems, it is often desirable to understand patterns in traveler demand. However, demand is typically unobserved and must be estimated from available data. To address this disconnect, we begin by proposing a method for recovering an unknown probability distribution given a censored or truncated sample from that distribution. The proposed method is a novel and conceptually simple detruncation technique based on sampling the observed data according to weights learned by solving a simulation-based optimization problem; this method is especially appropriate in cases where little analytic information about the unknown distribution is available but the truncation process can be simulated.
The proposed method is compared to the ubiquitous maximum likelihood (MLE) method in a variety of synthetic validation experiments where it is found that the proposed method performs slightly worse than perfectly specified MLE and competitively with slight misspecified MLE. We then describe a novel car-sharing simulator which captures many of the important interactions between supply, demand, and system utilization while remaining simple and computationally efficient. In collaboration with Zipcar, a leading car-sharing operator in the United States, we demonstrate the usefulness of our detruncation method combined with our simulator via a pair of case studies. These tools allow us to estimate demand for round trip car-sharing services in the Boston and New York metropolitan areas, and the inferred demand distributions contain actionable insights.
Finally, we extend the detruncation method to cover cases where data is noisy, missing, or must be combined from different sources such as web or mobile applications. In synthetic validation experiments, the extended method is benchmarked against kernel density estimation (KDE) with Gaussian kernels. We find that the proposed method typically outperforms KDE, especially when the distribution to be estimated is not unimodal. With this extended method we consider the added utility of search data when estimating demand for car-sharing.

Testo completoAbstract (sommario):
Strategies for generalizing raster-based land cover data were investigated. Generalization strategies were studied as part of the U.S. Geological Survey's (USGS) Federal Land Information System (FLIS). Area filtering, category aggregation, resampling, and modal search and replace comprised the strategies tested on USGS Alaska Interim Land Cover data.
Generalization of the land cover data was deemed necessary for two reasons: 1) reduction in the volume of homogeneous land cover regions required for computer memory storage, and 2) simplification of the highly complex land cover map. The generalization strategies were evaluated based upon how well they maintained the integrity of land cover information while minimizing the number of homogeneous land cover regions. Maintenance of land cover information after application of a generalization strategy was measured by omission and commission errors, percent unchanged, Cohen's statistic, and the number of land cover regions.Master of Science

Visualization enables new forms of social expression beyond the support of scientific data analysis. Focusing on the expanded roles of computational visualization, I investigate the influences of computation on the aesthetics and the rhetoric of visualization through design research methods. My design research includes 1) the construction of knowledge by synthesizing literature from digital media studies, visual rhetoric, information visualization, graphic design history, and HCI and 2) research through practices and consequent critiques. Coded visualization is a new term that I coined to integrate the rhetoric and aesthetics of data visualization. I define it as a data-based interface whose visual form is an aesthetic space where messages are coded and interpreted with cultural references. I also suggest the design criteria of coded visualization, apply them to a design project, and critique how the current design of the project can be improved to fully exemplify the concept of coded visualization. This study on the rhetoric and aesthetics of visualization through design research contributes to digital media studies, design research, as well as information visualization.

Thesis, Virginia Tech, 1998. http://hdl.handle.net/10919/36880.
Testo completoAbstract (sommario):
Economic justification for rehabilitative services has resulted in the need for outcome based research which could quantify success or failure in individual patients and formulate baseline variables which could predict outcomes. The purpose of this study is to investigate the utilization of baseline clinical, exercise test, and psychosocial variables to predict clinically relevant changes in exercise tolerance of cardiac patients who participated in early outpatient cardiac rehabilitation. Clinical records were analyzed retrospectively to obtain clinical, psychosocial and exercise test data for 94 patients referred to an early outpatient cardiac rehabilitation program at a large urban hospital in the Southeast US. All patients participated in supervised exercise training 3d/wk for 2-3 months. A standardized training outcome score STO) was devised to evaluate training effect by tabulating changes in patients predicted VO2, body weight and exercising heart rates after 8-12 weeks of exercise based cardiac rehabilitation. STO = Predicted VO2 change + BW change- HR change. The Multi-Factorial Analysis was applied to derive coefficients in the STO formula so that the STO scores reflected the independent effects of BW, HR and Predicted V02 changes on training outcome. Patients were classified into one of three possible outcome categories based on STO scores, i.e. improvement, no change, or decline. Thresholds for classifying patients were the following; STO scores greater than or equal to 3 SEM above the mean = improved, (N= 40: 41%), STO scores less than or equal to 3 SEM below the mean = decline, (N=34: 35%), STO scores within 3 SEM= no change, (N=23: 24%). Multiple logistic regression was used to identify patient attributes predictive of improvement, decline, or no change from measures routinely collected at the point of admission to rehabilitation. The model for prediction of improvement correctly classified 70% of patients as those who improved vs. those who did not (sensitivity 70%, specificity 71%). This model generated the following variables as having predictive capabilities; recent CABG, emotional status, social status, calcium channel blocker, recent angioplasty, maximum diastolic BP, maximum systolic BP and resting systolic BP. The model for predicting those who declined vs. those who did not decline demonstrated higher correct classification rate of 74% and specificity (84%). This model generated the following variables as having predictive capabilities; social status, calcium channel blocker, orthopedic limitation, role function, QOL score and Digitalis. However, these models may include certain bias because the same observations to fit the model were also used to estimate the classification errors. Therefore, cross validation was performed utilizing the single point deletion method; this method yielded somewhat lower fraction correct classification rates (66%,69%) and sensitivity rates (56%,44%) for improvement vs. no improvement and decline vs. no decline groups respectively. Conclusion A combined set of baseline clinical, psychosocial and exercise measures can demonstrate moderate success in predicting training outcome based on STO scores in hospital outpatient cardiac rehabilitation. In contrast psychosocial data seem to account for more of the variance in prediction of decline than other types of baseline variables examined in this study. Baseline blood pressure responses both at rest and during exercise were the greatest predictors of improvement. However, cross validation of these models indicates that these results could be biased eliciting overly optimistic predictive capabilities, due to the analysis of fitted data. These models need to be validated in independent sample with patients in similar settings.Master of Science

Testo completoAbstract (sommario):
Introduction Symptoms are universally experienced and can be bothersome. There have been comparatively few studies of common symptoms in the UK general population. As a result, little is known about the current epidemiology of common symptoms in the UK. There are major methodological challenges to conducting an epidemiological study of common symptoms in the community. Current knowledge about the most appropriate methodological tools for collecting and interpreting data on symptoms is limited. A range of methods has been used in previous studies, but the most appropriate method is not known. An evaluation of the different methods that could be used for investigating common symptoms in the community was therefore required. Aims The overall aim of this study was to investigate and compare the use of different approaches to collecting epidemiological data on common symptoms, with a view to developing an evidence-base for the use of these different approaches. Methods A general review of methods used in epidemiological studies and a comprehensive review of methods used in previous epidemiological studies of symptoms were undertaken. The reviews informed the development of symptoms survey. Symptoms survey was conducted to collect epidemiological data on common symptoms in the community. A total of 1179 individuals was approached from four GP practices in the Aberdeen area and sent an invitation letter, information sheet and consent form. Potential participants were requested to select at least two data collection instruments from four options (postal questionnaire, diary, online questionnaire and telephone interview). All the instruments collected the same data (presence of symptoms, severity of symptoms, management of symptoms and quality of life). This allowed a direct comparison of the data collected by the various measures. Those agreeing to participate in the study were sent one of their chosen instruments in phase one of the study and a second (but different) one of their chosen instruments in phase two, which was conducted three weeks later.

Testo completoAbstract (sommario):
A small private secondary school in Mexico implemented periodic progress testing with the intention of individualizing education of its students. The relationship between teachers' use of Measures of Academic Progress (MAP) data and students' mathematics and reading gain scores was not known. The purpose of this study was to determine whether the frequency of teachers' use of MAP data or student profiles was related to students' MAP mathematics and reading test gain scores between 2 years of test administrations. The theoretical framework for the study was Dewey's, Kolb's, and Vygotsky's ideas on pragmatism and constructivism, which support students' opportunities for growth in learning through realization of their strengths and talents. The mathematics and reading MAP gain scores of 76 students were examined, along with 8 teachers' responses from a questionnaire on teachers' frequency of use of MAP data or student profiles. Data were analyzed using analyses of variance. Results indicated significant differences in students' MAP gain scores in reading when their teachers reported using MAP data at least once per week (F = 4.086, p = 0.001) or online student profiles at least once per month (F = 3.638, p = 0.013). Targeted training videos and materials were created to support teachers' use of MAP results to inform instruction at the study site. Implications for social change include encouraging teachers and administrators to meet the individual needs of students, which may result in increased student reading and mathematics scores, graduation rates, and latitude in vocation selection.

Testo completoAbstract (sommario):
Vertical line arrays (VLAs) deployed below the critical depth in the deep ocean can exploit reliable acoustic path (RAP) propagation, which provides low transmission loss (TL) for targets at moderate ranges, and increased TL for distant interferers. However, sound from nearby surface interferers also undergoes RAP propagation, and without horizontal aperture, a VLA cannot separate these interferers from submerged targets. A recent publication by McCargar and Zurk (2013) addressed this issue, presenting a transform-based method for passive, depth-based separation of signals received on deep VLAs based on the depth-dependent modulation caused by the interference between the direct and surface-reflected acoustic arrivals. This thesis expands on that work by quantifying the transform-based depth estimation method performance in terms of the resolution and ambiguity in the depth estimate. Then, the depth discrimination performance is quantified in terms of the number of VLA elements.

Testo completoAbstract (sommario):
The research focus of this paper discusses digital game-based learning as a novel learning approach and further emphasises on the empirical study of technologies motivating Chinese primary students to study and learn mathematics at home. Considering that digital game-based learning is still under development, the effects of it is still controversial. The aim of this research is to examine family users of digital game-based learning systems through online research methods. It is interesting to study this area from the family users’ perspective because of the online context. In China, the concept of education in the family environment is one full of challenges. The design of a digital game-based learning (DGBL) system needs to consider and balance both parents and young learners’ needs. In order to have a comprehensive understanding of the benefits and issues of a DGBL system in China, a qualitative study was employed with an interpretive research approach using online data collection methods. After analysing the empirical findings, the results of the study will be produced. They will help to examine whether DGBL is a favourable approach to aiding Chinese primary students to study mathematics and improve their academic performances at school. The outcomes of this study are expected to contribute to informatic research and design of future DGBL systems.

Testo completoAbstract (sommario):
Aims: To investigate the role of perinatal factors in determining childhood health, development and school performance. Methods: Probabilistically linked population-based birth, death, hospital, child development and school performance data was used to investigate the association between study exposures and outcomes for a cohort of infants’ liveborn in New South Wales, Australia, 2000-12. Study exposures were gestational age, mode of birth, infant feeding and severe neonatal morbidity (SNM). Study outcomes included children’s 1) health: child hospitalisation for gastroenteritis or any infection; 2) development at ages 4-6 years: special needs; vulnerable or at-risk in one of five developmental domains; or being vulnerable ≥2 domains; and 3) school performance at ages 7-9 years: test exemption; or performing < -1 standard deviation (SD) in reading or numeracy tests. Results: Birth at gestations <39-40 weeks, by labour induction or caesarean section were each associated with an increased risk of hospital admission for gastroenteritis, first and repeat hospitalisation for any infection, being developmentally high risk, or at an increased risk of poorer development in language and cognitive skills, basic literacy and basic numeracy. Formula feeding was associated with an increased risk of hospital admission for gastroenteritis or any infection. Infants with SNM compared to those without, had greater odds of special needs at school age or being exempt from Grade 3 reading and numeracy tests. SNM infants were more likely to have poorer physical and cognitive development and achieve reading and numeracy test scores >1 SD below the mean. Conclusion: We demonstrate that key perinatal factors; gestational age with birth before 39-40 weeks, mode of birth, planned birth, formula feeding and severe neonatal morbidity play an important role in child health and development.

Testo completoAbstract (sommario):
Ce document met l'accent sur la caractéristique des informations de la Chine dans l'environnement complexe de l'information, à la recherche empirique sur la relation entre l'information caractéristique de la Chine avec le marché boursier, outre d'étudier le modèle de diffusion de l'information concernant les différentes caractéristiques de la Chine sur le marché boursier. Les deux données transversales et série temporelles sont appliquées en mesurant la dépendance à partir du micro-indicateur, et en outre au niveau macro d'étudier la dépendance liée au phénomène unique de la Chine . Dans l'étude du niveau micro, nous choisissons le lien politique comme le mode variable de l'information de la Chine. Nous avons découvert que différents liens politiques ont donné lieu à différentes performances de l'entreprise, ce qui affecte plus le rendement des actions à la fois sur le temps et l'échelle du rendement anormal. Dans les tests de la dépendance au niveau macro, nous introduisons l'approche copula empirique dans l'immobilier, le marché de l'or et des actions. Notre résultat a détecté la dépendance univariée parmi les trois marchés bien qu'ils soient deux à deux indépendants. Enfin, nous avions établi un marché immobilier et boursier artificiel pour analyser la réaction du marché boursier avec la politique de l'immobilier basé sur les caractéristiques de la Chine. Basé sur la recherche ci-dessus, nous concluons que la caractéristique des informations de la Chine a un effet sur le marché financier tant au niveau micro et macro, et canalisés entre eux. Ainsi, nous devons tenir en compte ces caractéristiques dans l'étude de l'analyse du marché financier de la ChineAfter recent financial crisis, financial asset clustered and fell together, although there was not significant dependent relationship detected in academic research. lt is an indisputable fact that the correlation and dependence between financial asset and market is far more beyond our current knowledge. On stock market studies, in the current "Big data" world, the complexity and wide variety information calls for research on the particular kind of information and its effect on the stock market. Thus, we could further study the relationship and dependence among financial asset to detect the information diffusion pattern in financial market. To achieve this objective, exiting data sources and analytics required to be improved. This paper focuses on the China characteristic information in the complex information environment, to empirically research on the relationship of China characteristic information with stock market, and further study information diffusion pattern regarding to different China characteristics in stock market. Both cross-seclional and time series data are applied with measuring dependence from micro indicators, and further studied the on the macro level dependence related to China unique phenomenon. ln micro level study, we choose political connection as information which is particular China pattern. By non-parametric analysis, we conclude different political connections resulted in different stock performance. Then we considered stock analyst recommendations as aggregated information proxy, applying event study to test the stock reaction to information controlling for political connection and ratings. We discovered that different political connection affect stock retum both on the lime and scale of abnormal return. ln testing for macro level dependence, we introduce empirical copula approach with stock, real estate and gold market. Our result detected univariate dependence among the three market although they are pairwise independent. Finally, we constructed an agent-based artificial stock and housing market to test the stock market reaction with housing market policy based on China characteristics. Based on the above research, we conclude that China characteristic information do have effect on the financial market from both micro and macro level, and channeled between them. Thus, we need to consider these characteristic in studying China financial market issue

Testo completoAbstract (sommario):
This thesis explores the transformations of evidence in health research synthesis studies – studies that bring together evidence from a number of research reports on the same/ similar topic. It argues that health research synthesis is a broad and intriguing field in a state of pre-formation, in spite of the fact that it may appear well established if equated with its exemplar method – the systematic review inclusive of meta-analysis. Transformations of evidence are processes by which pieces of evidence are modified from what they are in the primary study report into what is needed in the synthesis study while, supposedly, having their integrity fully preserved. Such processes have received no focused attention in the literature. Yet they are key to the validity and reliability of synthesis studies. This work begins to describe them and explore their frequency, scope and drivers. A ‘meta-scientific’ perspective is taken, where ‘meta-scientific’ is understood to include primarily ideas from the philosophy of science and methodological texts in health research, and, to a lesser extent, social studies of science and psychology of science thinking. A range of meta-scientific ideas on evidence and factors that shape it guide the analysis of processes of “data extraction” and “coding” during which much evidence is transformed. The core of the analysis involves the application of an extensive Analysis Framework to 17 highly heterogeneous research papers on cancer. Five non-standard ‘injunctions’ complement the Analysis Framework – for comprehensiveness, extensive multiple coding, extreme transparency, combination of critical appraisal and critique, and for first coding as close as possible to the original and then extending towards larger transformations. Findings suggest even lower credibility of the current overall model of health research synthesis than initially expected. Implications are discussed and a radical vision for the future proposed.

Testo completoAbstract (sommario):
Evidence synthesis is considered a corner stone of modern health care and clinical practice. Systematic reviews of randomised trials, when undertaken with meta-analysis provide summary estimates on the effectiveness of interventions. However, the findings of meta-analysis are often limited by the selective reporting of primary studies, and the variations in population, intervention and outcomes. Furthermore, difficulties in disentangling the study and individual level associations in meta-analysis make them susceptible to ecological fallacy, and may lead to incorrect conclusions. Meta-analysis using Individual Participant Data (IPD) has the potential to overcome many of the above limitations, by using raw trial data. Access to IPD minimises problems from incomplete or incorrect reporting of trial outcomes, by verifying reported results, and by standardising the definition of outcomes where possible. Importantly, this allows detecting any variation in the effects of interventions according to characteristics of the participants. Amalgamated individual datasets assembled to address the effectiveness question, can be further used to explore secondary objectives such as the relationship between surrogate and clinical outcomes. This maximises the use of available clinical data, and addresses the problem of research waste. In this thesis, I evaluated the effects of diet and physical activity based interventions in pregnancy on maternal and offspring outcomes using both study-level and IPD meta-analyses, and assessed the differential effects of interventions on outcomes according to mother's BMI pre or in early pregnancy. I reviewed the variation in outcomes reported in this field, and developed composite outcomes for IPD meta-analysis. I also evaluated the relationship between weight gain in pregnancy and clinical outcomes in pregnancy using the IPD meta-analysis methodology. Aims The aim of this thesis was to evaluate the effects of diet and physical activity based interventions in pregnancy on clinical outcomes using standard and advance methods of evidence synthesis; assess the variation in outcomes and their clinical importance in a trial with those interventions and examine the relationship between gestational weight gain and important clinical outcomes. Methods Delphi methodology, systematic reviews of literature, and meta-analyses using study-level and individual participant data of randomised controlled trials (RCTs). Results Composite outcomes Developed composite outcomes comprise of four maternal (gestational diabetes, hypertensive disorders in pregnancy, preterm birth, caesarean section) and four offspring outcomes (stillbirth, small for gestational age, large for gestational age, and admission to neonatal intensive care unit). The components to assess maternal composite outcome were available in two-thirds (66.7%, 24/36) and for offspring composite in half (50%, 18/36) of the studies in the IPD meta-analysis. The effect of interventions was not statistically significant neither on the maternal nor on the offspring composite - Odds Ratio (OR) 0.90 (95% CI 0.79, 1.03) and OR 0.94 (95% CI 0.83, 1.08), respectively. The direction of the pooled effect was consistent between the composite and its components for the maternal composite and variable for the offspring outcomes. 6 Effects of diet and physical activity based interventions The IPD meta-analysis of 36 RCTs (>12 500 women) showed a significant effect of diet and physical activity based interventions in pregnancy in reducing gestational weight gain (Mean Difference -0.70 kg, 95% CI -0.92, -0.48) and chance of caesarean section delivery (OR 0.91, 95% CI 0.83, 0.99) in comparison to routine antenatal care. There was no effect of the interventions on any of the offspring complications. Incorporation of outcome data unavailable on study-level returned more modest magnitude of the summary estimates in comparison to effects obtained using study-level data of trials that shared IPD. The addition of study-level data from non-IPD trials changed the magnitude and the statistical significance of the summary effects on GDM - from OR 0.89 with only IPD (95% CI 0.72, 1.10; 27 studies, 9 427 women) to OR 0.76 (95% CI 0.65, 0.89; 59 studies, 16 885 women). It has also changed the funnel plot structure in the meta-analysis for gestational weight gain (Egger's test p = 0.04 with only IPD to p= 0.61). The IPD meta-analysis shows that the effects of diet and physical activity based interventions on the maternal and the offspring outcomes did not differ by women's BMI status. While the study-level meta-regression indicated that the interventions might reduce gestational weight gain stronger for the obese women - coefficient -0.22 (95% CI -0.33, -0.11) for each 10% change in the proportion of women in the obese class. Outcomes in trials with diet and physical activity based interventions 66 primary publications from trials with diet and physical activity based interventions in pregnancy reported 142 outcomes. Half of those outcomes appeared in the publications once (72/142). 'Critically important' outcomes are reported less often in comparison to 'non-critical' ones (15.5%, 22/142 vs 68.3%, 97/142). The overall quality of outcome reporting varied between trials with the least frequently provided information on the methods to improve the quality of outcome measures (33.3%, 22/66 publications). 7 Gestational weight gain and pregnancy outcomes IPD from 4 429 pregnant women randomised to the control arms of RCTs with diet and physical activity based interventions were available for the analysis. Women who most often exceeded the IOM recommendation belonged to the overweight (51.5%, 641/ 1 245 women) and the obese groups (44.5%, 695/ 1 562 women) while women with normal BMI most often gained below the recommended amounts (40%, 649/1 622 women). Each kilogram of gestational weight gain within the IOM ranges was not link with a change in the chances of preterm birth, caesarean section, or birth of LGA and SGA infant. Not achieving of the recommended weight was associated with the decreasing chance of giving birth to LGA infant with each kilogram below the lower limit among the obese women (OR 0.80, 95% CI 0.65, 0.99). Each kilogram of weight gain above the upper limit was associated with an increase in the chance of caesarean section (adjusted 1.04, 95% CI 1.01, 1.08) and delivering LGA infant (adjusted 1.08, 95% CI 1.05, 1.12) regardless on women's BMI status. Conclusions Diet and physical activity based interventions in pregnancy moderately reduced gestational weight gain and decrease the odds of caesarean delivery. Overall, IPD meta-analysis improved the robustness of the evidence synthesis of RCTs with diet and physical activity based interventions. However, more attention is needed for the data-related issues in IPD meta-analysis as the purported benefits of the method are not always practically realised. The use of the composite outcomes was hampered by the variable availability of important clinical outcomes. The introduction of minimal core outcome set would facilitate the comparison of the wide range of the evaluated interventions and improve implementation of the composite outcomes. Gestational weight gain was found to be associated with the odds of delivering LGA infant and caesarean section. Future research should aim to collect and report a minimal set of outcomes, and ensure better reporting of study conduct and its findings.

Approved for public release; distribution is unlimitedIn the field of human research, particularly in operational environments, data collection techniques are difficult. Researchers often focus their efforts on the data analysis and overlook the shortcomings of their data collection and storage methodologies. In order to demonstrate effective data collection and storage methodology in a representative human research process, the process used by human fatigue and performance researchers at the Human Systems Integration Lab at Naval Postgraduate School (NPS) served as a Proof of Concept. Most recent studies conducted at NPS provided a model of the current process. The Knowledge Value Added (KVA) methodology was used as a tool of comparison of the current process to the reengineered process. Information technologies including wireless physiological monitoring devices, web-based and mobile device data collection methods, and integrated data storage techniques were incorporated in the reengineering effort. The data storage process included the design of a standard relational database format allowing research teams to easily access their data. This repository also enables data to be archived for future use (e.g., meta-analyses). To demonstrate the reengineered process in an operational environment, a field fatigue study was conducted at the Naval Officer Indoctrination School (OIS) in Newport, Rhode Island.

The allocation of resources and the constant search for competitive advantages differentiators to reach best results are always business challenges. In the contemporary context, in order to achieve superior performance, it reinforces the company's need to have, and make good use, of scarce, valuable, non-substitutable and inimitable resources. These resources include brands, customer base, knowledge, ability and competence of the work teams, corporate culture, partnerships and operational processes established, among other intangible assets, usually arising from a long and risky development process. Mergers and acquisitions (M & A) arise, then, as an important strategic action, being an alternative means to obtain and accelerate the accumulation of these resources within the companies. That is the subject of this work, which discusses the importance of existing and intangible assets disclosed, previous to the M & A transactions, their classification into various types, measurement, and impact on the resulting firm's financial performance in long term. The overall objective of this thesis was to analyze how this performance, after a minimum period of 36 months of the event, is related to the existence, level of disclosure and the nature of intangible assets in the organizations involved. One hundred-eighteen (118) companies were investigated in fifty-nine (59) cases of M & A occurred in France between 1997 and 2007; the study reflects a multi-method research, pluralistic, on qualitative and quantitative aspects. Intangible assets disclosure indicators were built by applying the content analysis technique to financial and accounting reports provided by the companies prior to the events, as well as financial indicators (proxies) for the existence of intangibles were calculated. These indicators were initially confronted with each other and later their explanatory power in relation to financial ratios of growth and profitability (for the corporation and its shareholders), which are the analyzed dimensions of financial performance. Many methods for statistical analysis were used in the multivariate data analysis (correlations and factor analysis, multiple regressions) and in the structural equation modeling (SEM), via Partial Least Squares (PLS). A total of twelve models, with statistics significance, were established to express the relationship among the constructs examined. Best results were achieved in the models developed with variables of semantic origin, in detriment of those with financial indicators only. The results obtained in this thesis leads to deduce that, in this study, there are positive relationships between the existence and the disclosure of intangible assets by firms involved in the operations of M & A and subsequent financial performance, measured by the corporate profitability and the growth of the resulting organization. This suggests that the strategic choice for business growth via M & A operations is favorable to the accumulation of intangible assets in the firms, in search for better results.
A alocação de recursos e a constante busca por diferenciais competitivos, visando melhores resultados, são grandes desafios empresariais. No contexto contemporâneo, para obter desempenho superior, reforça-se a necessidade de a empresa dispor, e fazer bom uso, de recursos raros, valiosos, não-substituíveis e de difícil imitação. Dentre estes recursos, destacam-se aspectos como as marcas, a base de clientes, o conhecimento, a capacidade e competência das equipes de trabalho, a cultura corporativa, as parcerias e os processos operacionais estabelecidos, dentre outros ativos intangíveis, geralmente decorrentes de longos e arriscados processos de desenvolvimento. As fusões e aquisições (F&A) surgem, então, como movimentos estratégicos importantes, sendo meio alternativo para obter e acelerar a acumulação destes recursos nas empresas. É essa a temática deste trabalho, que discorre sobre a importância dos ativos intangíveis existentes e divulgados previamente às operações de F&A de empresas, sobre a classificação dos seus diversos tipos, a sua mensuração e o seu impacto sobre o desempenho financeiro da firma resultante, no longo prazo. O objetivo geral desta tese foi analisar como este desempenho, após prazo mínimo de 36 meses do evento, está relacionado à existência, ao nível de divulgação e à natureza dos ativos intangíveis das organizações envolvidas. Foram investigadas 118 empresas, em 59 casos de F&A ocorridos na França entre 1997 e 2007, em uma pesquisa multi-métodos, pluralística, nas vertentes qualitativa e quantitativa. Foram construídos indicadores de divulgação (disclosure) de ativos intangíveis, mediante aplicação da técnica de análise de conteúdos aos relatórios contábil-financeiros disponibilizados pelas empresas antes do evento, e calculados indicadores financeiros (proxies) para a existência de intangíveis. Estes indicadores foram inicialmente confrontados entre si e posteriormente quanto ao seu poder explicativo em relação aos índices financeiros de crescimento e de lucratividade (empresarial e para os acionistas), que são as dimensões analisadas do desempenho financeiro. Utilizaram-se métodos de análise estatística de dados multivariados (análises de correlações, fatoriais, regressões múltiplas) e modelagem em equações estruturais, via Partial Least Squares (SEM- PLS). Foram estabelecidos, no total, doze modelos com significância estatística para expressar o relacionamento entre os construtos examinados. Alcançaram-se melhores resultados nos modelos desenvolvidos com variáveis de origem semântica, em detrimento daqueles que utilizaram indicadores exclusivamente financeiros. Os resultados obtidos nesta tese permitiram deduzir que há relações positivas entre a existência e a divulgação de ativos intangíveis pelas firmas envolvidas nas operações de F&A estudadas e o posterior desempenho financeiro, mensurado pela lucratividade empresarial e pelo crescimento, da organização resultante. Isto sugere que a opção estratégica por crescimento empresarial via operações de F&A é favorável ao acúmulo de recursos intangíveis nas firmas, na busca por melhores resultados.

Testo completoAbstract (sommario):
This study sets out to interpret pupils’ and teachers’ perceptions about learning in visual arts in the context of the third year visual art class of one of the three specialist arts schools in Greece. The rationale for the research was to understand how pupils and teachers in this type of specialist arts school perceived the learning process, which could have some transfer value to other contexts of learning in the visual art subject. The research may contribute to the body of knowledge and the practice of art education in Greece, and possibly inform future curriculum development in the subject. In Greece, since 1985, the development of art education and pupils’ aesthetic understanding has been one of the five fundamental aims for secondary and primary education. To improve art education at the primary and secondary level, the Greek Ministry of National Education and Religious Affairs has undertaken several initiatives. One such initiative has been the development of specialist arts schools. These alternative specialist schools exist in several European countries. In 2003 the Greek Ministry of Education announced the establishment of the first arts school of the country. The year the research was conducted 2008-2009, three arts schools were operated in Greece. The research endeavoured to understand issues related to the learning process in one of the new specialist arts schools, as perceived by third year pupils (aged fourteen and fifteen years old) and their visual art teachers. The research used the interpretive research paradigm, as it is the most suitable method to explore the socio-cultural reality in which the pupils and teachers are situated. Qualitative data were collected using semi-structured interviews, observations, and focus groups. The analysis of findings revealed a learning experience very closely related with the philosophy and the content of the Greece’s national curriculum of visual art. However, according to the findings of this study further attention needs to be given to the issue of developing imaginative thinking, within the framework of the art curriculum. The study proposes an alternative version of the art curriculum, with a view to facilitating imaginative thinking, in the art curriculum of specialist arts schools in Greece as well as the teaching of art in normal secondary schools. It is hoped that the results of the study will offer ground for discussions and oppositions in the area of art education in Greece, in which area not much research has been undertaken. The study’s proposal for the revisions to the existing art curriculum for the specialist arts schools, as they are resulted from evidences embedded in pupils and teachers views, stress on the significance and the originality of the findings and for this reason it is hoped to concern the writing aspect of Greece’s future curriculum writers. This will add to the development of art education in Greece and further will foster relationships between the members of the particular school where the research was carried out.

This research used network remote monitoring technology on building energy. Digital electric meters were used to acquire the energy consumption data for building equipment. The data were transmitted to the university energy monitoring center through signal processing with certain communication protocol. The energy data thus acquired for the building equipment were analyzed for energy trend and energy use distribution. Further, the energy indices such as the unit area building energy use intensity (EUI ,kWh/m2yr) and unit area demand use intensity (DUI, W/m 2), etc, were analyzed and used for energy comparison and data base construction. This research also analyzes the building energy by using the authoritative dynamic building energy modeling program DOE-2. Some health buildings in the data base were used in the analysis. Results of computation were compared to those of the analysis, for major energy factors. Energy conservation potentials were explored with some energy saving measures for health buildings of different sizes. This research began with layout of building energy monitoring standard procedures, sample selection, building equipment survey, and year long hourly real time energy monitoring. The measured energy data were analyzed with DOE-2 for key energy factors and energy indices. The energy factors and energy indices were then compiled together with the measured data to be the energy data base for health buildings. This research also analyzed the effects of energy conservation measures. The data base thus built up in this research is unprecedented in Taiwan and will contribute to the understanding of the energy characteristics of health buildings. The research results and energy data thus built up are important to the energy management of health buildings in Taiwan.

Fechner, Harry H. E. "Data base accuracy and integrity as a precondition for overhead allocations". Thesis, 2004. http://handle.uws.edu.au:8081/1959.7/807.
Testo completoAbstract (sommario):
Interest in more accurate assignment of overhead costs to establish credible product/service cost profiles has assumed substantial prominence in much of the recent debates on management accounting practices. While the promotion of new cost management systems and in particular Activity Based Costing (ABC) has promised to address many of the perceived shortcomings of more traditional and long established techniques, the lack of its implementation success raises some concern as to the validity and value of these new system designs. A major purpose of this thesis is the development of a mathematical model that is capable of computing overhead allocations on the basis of organisational specific dimensions other than DLH.While almost all data bases suffer from data entry and omission errors, the information content contained in the data bases often forms the basis for management decisions without first confirming the accuracy of the data base content. The model has been successfully applied and tested to detect internal consistency and data element detail accuracy. Future research may test the applicability of the model with more diverse data bases to confirm its generalisability as an investigative as well as predictive model.
