Regionální disparity v uplatnění absolventů vysokých škol na trzích práce v krajích ČR / Regional disparities in the use of graduates in the labor markets in the regions NUTS 3 of the Czech Republic

Michalovská, Zdeňka January 2011 (has links)
This master thesis focuses on the issues of application of the graduates in the labor market. The main objective is to identify and evaluate disparities in the use of graduates in the labor markets in the regions NUTS 3 of the Czech Republic. To fulfill the main objectives and targets have been selected the partial targets namely: the recent development of the quantity of universities and their students from 1989 to the present, the current location of universities in the regions NUTS 3 and the development of graduates over time and according to type of university degree, programs disciplines and gender. The theoretical part is devoted to the definition of basic concepts, application of the relation of education to individuals in the labor market and educational system in the Czech Republic and especially is devoted to tertiary education. The practical part consists of analyzes of trends in the number of graduates from different perspectives andanalyzesthe applicationof universitygraduates,such as the analysis of supply and demand for university graduates and the amount of their income. Because of the result of analysis was possible to identify and evaluate a number of regional differences in the use of graduates in the labor markets in the regions NUTS 3. The differences are formulated at the end of the master thesis.

Komparativní analýza trendů meziregionální migrace obyvatel v České republice a v Rakousku v letech 1992-2010 / Comparative analysis of interregional migration trends in the Czech Republic and Austria in the period 1992-2010

Feřtrová, Jitka January 2012 (has links)
Internal migration is one of the possible ways to reduce unemployment within the country. The aim of this paper is to compare the volume of internal migration between NUTS II regions in the Czech Republic and Austria and to try to identify factors that act to the migration flows. The results show that Austria is characterized by increased internal migration, international migration, as well as commuting to work in another region. Since the Czech Republic all these indicators lagging behind, it is necessary to determine whether the internal migration of both states is influenced by the same factors. Specifically, the paper examined the relationship of interregional migration and the average disposable income, unemployment rate, number of vacancies, the size and distance of regions, using the method of multiple linear regression analysis. While in the Czech Republic the internal migration is motivated by economic factors, in Austria, the relationship of migration and selected variables was not confirmed. The paper finds that residents of Austria are more active in terms of migration, but this move has obviously other than economic incentives.

Vliv finanční krize na konvergenci regionů Spolkové republiky Německo

Konvalinová, Vendula January 2017 (has links)
This diploma thesis deals with the impacts of financial and economic crisis on thirty-eight NUTS 2 regions of Germany. This includes identifying trends in regional convergence/divergence for the reference period 2004-2013 and determining the probable cause of observed disparities. For this purpose, cluster analysis and beta-convergence analysis are applied and conducted for the periods before and at the start of the financial crisis and during the outbreak of the economic crisis and after its overcoming. The impacts of the crisis on economic development of each region are also investigated by using important macroeconomic indicators.

Ověření vztahu makroekonomických ukazatelů a počtu nařízených exekucí dle územního členění

Kotrbová, Denisa January 2018 (has links)
The diploma thesis deals with the question of how the economic development affects the ability of the indebted persons to repay the loans. The aim of this diploma thesis is to perform its own verification and subsequent proof of causality between the number of ordered executions and selected macroeconomic indicators in the time period 2010-2016. The research question will be answered whether there is a link between the macroeconomic indicators of the NUTS II CZ regions and the number of ordered executions. Literary research is focused on regional disparities, aspects of ordered executions, methods of executions, course of ordered executions and legislative modification. The subject of the empirical part is a multidimensional analysis of panel data, through which the obtained outputs are used to answer the research question.

Les structures en creux du site mésolithique d'Auneau "le Parc du Château" (Eure-et-Loir) : nouveau bilan et implications concernant le mode de vie des dernières populations de chasseurs-collecteurs en Europe / The Mesolithic pits at "Le Parc de Château" in Auneau (Eure-et-Loir - France) : a new report and its relationship with the latest European hunter-gatherer way of life

Verjux, Christian 30 January 2015 (has links)
Ce travail s'appuie sur un nouveau bilan concernant les 70 structures en creux mésolithiques du site du « Parc du Château » à Auneau (Eure-et-Loir), datées entre 8 000 et 5 500 ans avant J.-C. Leurs fonctions variées — sépultures, dépôts intentionnels de restes animaux, foyers en fosse, calages de poteau, extraction, stockage, dépotoirs — évoquent des installations d'une certaine durée. Une enquête étendue à une bonne partie de l'Europe permet de recenser plus d'une centaine d'autres sites mésolithiques livrant des structures analogues, parfois en grand nombre. Il en ressort une image très éloignée de la vision traditionnelle de ces sociétés (cf. chasseurs-collecteurs très mobiles aux campements temporaires sommairement aménagés). Deux types de structures retiennent particulièrement l'attention : les fosses destinées au stockage alimentaire enterré (cf. silos) laissent envisager une consommation différée de fruits à coque (noisettes, glands) permettant de s'affranchir des cycles saisonniers ; les fosses-dépotoirs attestent, quant à elles, une gestion des déchets évoquant des installations durables. On en déduit que le développement de stratégies de subsistance adaptées à un riche environnement post-glaciaire a pu favoriser la sédentarisation de certains groupes de chasseurs-collecteurs stockeurs dès le Mésolithique moyen — bien avant donc les premiers contacts avec les populations néolithiques. L'apparition des premiers cimetières en Europe constitue un autre indice très évocateur d'une restriction de la mobilité, également perceptible à travers certains impacts anthropiques sur le milieu et divers types d'équipement (outillage lourd, vannerie, pirogues, pêcheries). / Our research leans on new analysis about the Mesolithic pits discovered during the excavation at "le Parc du Château" in Auneau (Eure-et-Loir; France). These 70 pits date between 8.000 and 5.500 cal. BC. Their various functions — i.e. graves, faunal hoards, pit-hearths, post-holes, extraction, storage, rubbish dumps — evocate long duration settlements. A European survey links to record more than 100 sites With such features, sometimes very numerous. These new data provide an original pattern, quite different from the traditional models of very mobile hunter-gatherer and short time encampment. Two kinds of features seem to be especially significant: food storage pits (similar to silos) may have allowed a delayed consumption of nuts (hazelnut or acorn) providing the bulk of food during the season of scarcity; rubbish pits indicate waste management linked to long term dwellings. From our point of view new subsistence strategies related with rich post-glacial environmental resources may allow some storing hunter-gatherer groups to adopt a sedentary way of life Since the middle Mesolithic — i.e. several millennia before the first interactions with Neolithic populations. The emergence of actual cemeteries in Euro e at the same period reveals also decreasing mobility evidence likewise some anthropogenic impacts on the environment and various equipment such as heavy lithic tools, basketry, pirogue, fishery, and so on.

Analytical and experimental investigation of a flush moment end-plate connection with six bolts at the tension flange

Bond, Douglas Edward January 1989 (has links)
An analytical and experimental investigation was conducted to study the six bolt flush moment end-plate connection configuration which is used in steel frame construction. The limit states of plate yielding and bolt fracture were analyzed using yield-line theory to predict endplate thicknesses and a split-tee analogy to develop a method to predict bolt forces. Five experimental tests were conducted on four configurations within a matrix of geometric parameters. The predicted ultimate moment showed good . correlation to the yield moment obtained from the experimental deflection plots. The experimental bolt forces correlated well with the predicted bolt forces when plotted versus the applied moment. Additionally, an equation to model the moment-rotation relationship was developed from a regression analysis to determine the construction type suitable for a given connection configuration. Finally, a method of designing the six-bolt flush end-plate configuration is presented and an example given. / Master of Science

Performance of snug tight bolts in moment end-plate connections

Kline, Donald Paul 09 May 2009 (has links)
An experimental investigation was conducted to study the behavior of snug tight ASTM A325 bolts in moment end-plate connections for use in single story buildings. Wind loading was deemed to be the critical loading on snug tight bolt, moment end-plate connections. A test loading sequence was established based on a statistical analysis of the 50-year wind loading on low rise buildings. Eleven specimens, representing six end-plate configurations, were tested under cyclic loading covering expected wind loads in the range of 33 to 100 percent of the connection design (allowable stress design) moment. Following the cyclic loading, the specimens were statically loaded to failure, and the experimental strengths were compared with predicted strengths for connections with fully tightened A325 bolts. Additionally, the effect of snug tight bolts on connection stiffness are considered. Finally, recommendations for the use of snug tight bolts in moment end-plate connections were provided. / Master of Science

Time-to-Event Modeling with Bayesian Perspectives and Applications in Reliability of Artificial Intelligence Systems

Min, Jie 02 July 2024 (has links)
Doctor of Philosophy / With the fast development of artificial intelligence (AI) technology, the reliability of AI needs to be investigated for confidently using AI products in our daily lives. This dissertation includes three projects introducing the statistical models and model estimation methods that can be used in the reliability analysis of AI systems. The first project analyzes the recurrent events data from autonomous vehicles (AVs). A nonparametric model is proposed to study the reliability of AI systems in AVs, and a statistical framework is introduced to evaluate the adequacy of using traditional parametric models in the analysis. The proposed model and framework are then applied to analyze AV data from four manufacturers that participated in an AV driving testing program overseen by the California Department of Motor Vehicles. The second project develops a survival model to investigate the failure times of graphics processing units (GPUs) used in supercomputers. The model considers several covariates, the spatial correlation, and the correlation among multiple types of failures. In addition, unique spatial correlation functions and a special distance function are introduced to quantify the spatial correlation inside supercomputers. The model is applied to explore the GPU failure times in the Titan supercomputer. The third project proposes a new Markov chain Monte Carlo sampler that can be used in the estimation and inference of spatial survival models. The sampler can generate a reasonable amount of samples within a shorter computing time compared with existing popular samplers. Important factors that can influence the performance of the proposed sampler are explored, and the sampler is used to analyze the Titan GPU failures to illustrate its usefulness in solving real-world problems.

Association between Frequency of Consumption of Fruit, Vegetables, Nuts and Pulses and BMI: Analyses of the International Study of Asthma and Allergies in Childhood (ISAAC).

Wall, Clare R, Stewart, Alistair W, Hancox, Robert J, Murphy, Rinki, Braithwaite, Irene, Beasley, Richard, Mitchell, Edwin A 07 March 2018 (has links)
Diets which emphasize intakes of plant-based foods are recommended to reduce disease risk and for promoting healthy weight. The aim of this study was to examine the association between fruit, vegetables, pulses and nut intake and body mass index (BMI) across countries in adolescents (13-14 years) and children (6-7 years). Data from the International Study of Asthma and Allergies in Childhood; 77,243 children's parents and 201,871 adolescents was used to examine the association between dietary intake (Food Frequency Questionnaire) and BMI using general linear models, adjusting for country gross national index. Adolescents who consumed fruit, vegetables, pulses and nuts three or more times a week had a lower BMI than the never or occasional group; eating nuts three or more times a week, was associated with a BMI value of 0.274 kg/m² lower than the never group (p < 0.001). Compared to children who never or occasionally reported eating vegetables, those reporting that they ate vegetables three or more times per week had a lower BMI of -0.079 kg/m². In this large global study, an inverse association was observed between BMI and the reported increasing intake of vegetables in 6-7 years old and fruit, vegetables, pulses and nuts in adolescents. This study supports current dietary recommendations which emphasize the consumption of vegetables, nut and pulses, although the effect sizes were small. / Acknowledgments: This work was supported by Cure Kids New Zealand through a grant to E.A.
