Thesis have quantified the total number of students from 1999 until 3th March, 2015 who graduated within the excess year after the standard length of study (SDS). During the reporting period, the total number of finished studies in SDS plus anadditional semester totalled nearly 130,000 students, in SDS plus an additional one year were then finished 117,000 studies. The total number of failed studies, which ended up in the additional extra year in period is 40,000, of which 28,000 in SDS plus one semester and 12,000 in SDS increased by one year. Direct costs of the prolonged studies were estimated at 1.1 billion Kč for 2014. Of which 200 million are sunk costs to studies that have not been completed successfully. The work also calculated the opportunity costs in terms of revenue that could have Czech Republic earned, if the student have finished in SDS and have worked which was estimated at 4.7 billion Kč including both direct and indirect taxes.

La presente investigación tiene como objetivo analizar la influencia de la educación en la decisión de migrar internamente de un individuo en el Perú. En este caso, la variable educación es representada por la escolaridad promedio de la región, así como por la oferta educativa disponible. El periodo de análisis abarca los años comprendidos entre 2016-2020, dado que la migración reciente evalúa la residencia actual del individuo y el lugar donde residía cinco años atrás. En base a la teoría del capital humano, se plantea que la educación de la región de destino se comporta como un factor de atracción que mejora el bienestar del individuo, si este decide migrar. De esta manera, con la finalidad de evaluar la hipótesis planteada, se propone una estimación a través del modelo Logit, la que confirma que el nivel educativo de la región de destino es un factor significativo y de relación positiva con la decisión migratoria. / The present research aims to analyze the influence of education on an individual’s decision to internally migrate in Peru. In this investigation, the education variable is represented by the average schooling in the region, as well as by the regional education availability. The analysis period covers the years between 2016-2020, since recent migration evaluates the individual’s current residence and the place where he resided five years ago. Based on the human capital theory, it is proposed that education in the destination region behaves as a pull factor which improve the individual’s well-being if he decides to migrate. Thereby, a logit model is used to evaluate the hypothesis. The results confirm that the educational level of the destination region is a significant and positively related factor to the migration decision. / Trabajo de investigación

Sweden faces shortages in antibiotics. Shortages are caused due to a variety of reasons. Due to low profit margins and opportunity costs, antibiotic supply chains may experience a lack of competition. Lack of competition across the various stages of supply chains leads to fragility in the supply chain which ultimately results in shortages. Lack of communication is another such factor leading to shortages. Incorporating an AI/IT system across the supply chain would help prevent the occurrence of shortages by addressing such factors.  PLATINEA, an innovation platform, aims to address the threat of anti-microbial resistance by ensuring a steady supply of antibiotics. Their work package 4 is dedicated to eliminating risk factors or causes of shortages that arise from supply chains of antibiotics. PLATINEA has drafted a mind map to identify the risk factors or causes of shortages in Sweden. This thesis revolves around conducting a cost benefit analysis for implementing an AI/IT tool that addresses the risk factors and causes of shortages identified from the mind map that stem from the Swedish supply chains of antibiotics. A model consisting of a breakdown in costs and benefits was created. The model not only helped us frame the various costs and benefits, but also evolved during the research to help us structure our results better. An AI/IT tool has been devised keeping the risk factors and causes of shortage in mind. This tool has four versions that have varying levels of integration and automation. Semi-structured Interviews were conducted with experts in the field of artificial Intelligence and machine learning. calculation based on historical data were made to determine costs of shortages and to some extent, visualize the extent of costs involved in antibiotic resistance. Based on the information gathered from the interviews and literatures, the costs and benefits identified in the model are addressed, including the significant benefit of reducing cost of shortages.

As descargas atmosféricas causam prejuízos às concessionárias de energia elétrica, aos consumidores e à sociedade como um todo. Diferentes métodos podem ser utilizados para melhorar a confiabilidade do sistema elétrico e a qualidade da energia fornecida aos consumidores. Entretanto, as sobretensões atmosféricas variam em função de diversos parâmetros, de modo que a eficácia de determinada alternativa de proteção depende não apenas da configuração da rede, mas também das características da região, especialmente da densidade de descargas atmosféricas e da resistividade do solo. Consequentemente a relação custo-benefício correspondente a cada alternativa também depende das características de cada região. É importante, portanto, dispor de um modelo para realizar essas avaliações levando em conta todos os fatores envolvidos no processo, de forma a auxiliar as empresas de energia na tomada de decisões sobre investimentos em proteção contra descargas atmosféricas. Entretanto, modelos de análise de viabilidade que permitam a obtenção de conclusões econômicas amplas para dar suporte à tomada de decisões não são normalmente utilizados em função da complexidade dos fenômenos associados às descargas atmosféricas e à dificuldade na construção de modelagens econômicas neste contexto. Para preencher esta lacuna, este trabalho propõe um modelo para análise do custo e benefício da implantação de sistemas de proteção contra descargas atmosféricas em redes de distribuição considerando os investimentos, a redução da indisponibilidade e os custos evitados para a distribuidora e a sociedade. A análise financeira é feita com base na taxa interna de retorno dos investimentos e na razão entre custos e benefícios, o que facilita a análise de sensibilidade e permite determinar as condições nas quais a alternativa será viável. O modelo considera a indisponibilidade de energia e a inconfiabilidade do sistema a partir dos indicadores de duração equivalente de interrupção por unidade consumidora (DEC) e da frequência equivalente de interrupção por unidade consumidora (FEC), respectivamente. Os custos evitados devido à redução da indisponibilidade são tratados como benefícios. É utilizado para analisar as condições nas quais a aplicação de um determinado método de proteção em uma determinada rede é técnica e economicamente viável. Faz-se também uma análise de sensibilidade, sendo discutidas as influências de vários parâmetros nas relações custo-benefício correspondentes às regiões estudadas. O que na realidade não limita o modelo à análise de investimentos para melhoria do desempenho de redes de distribuição frente a descargas atmosféricas, mostrou-se prático e de grande utilidade na tomada de decisões quanto à realização de determinado investimento considerando as características da região e a efetividade do método de proteção analisado. / Lightning causes damages and losses to power companies, consumers, and the society as a whole. Different methods can be used to improve the power quality and the reliability of the electrical system. However, lightning overvoltages depend upon several parameters, so that the effectiveness of a certain protection alternative depends not only on the network configuration but also on the characteristics of the region, especially the ground flash density and the soil resistivity. Consequently, the cost-benefit ratio corresponding to each alternative depends also on the characteristics of each region. It is important, therefore, that the model for conducting these assessments be capable of taking into account all the factors involved in the process so that it can assist power companies in making decisions on investments in lightning protection. However, models of feasibility analysis that enable to obtain broad economic conclusions to support decision-making are not normally used due to the complexity of the phenomena associated with lightning overvoltages and the difficulty in constructing economic models in this context. For this reason this work proposes a model for the analysis of the cost and benefit of the implantation of lightning protection systems in distribution networks considering the investments, the reduction of the unavailability, and the costs avoided for the distribution power company and the society. The financial analysis is based on the internal rate of return on investments and the cost-benefit ratio, which facilitates the sensitivity analysis and allows for the determination of the conditions under which the alternative will be feasible. The model considers the energy unavailability and the unreliability of the system from the indicators of equivalent duration of interruption per consumer unit (DEC) and the equivalent frequency of interruption per consumer unit (FEC), respectively. The costs avoided due to the reduction of unavailability are treated as benefits. The model is used to analyze the conditions under which the application of a given protection method in a given network is technically and economically feasible. A sensitivity analysis is also done and the influences of several parameters on the cost-benefit ratios corresponding to the regions studied are discussed. However the model, which actually is not limited to the analysis of investments to improve the lightning performance of power distribution networks, has proved to be practical and very useful in the decision-makingregarding the realization of a given investment taking into account the characteristics of the region and the effectiveness of the protection method analyzed.

In this research, the hypothesis that the criminals migration to illegal activities was in the hope of earning more than the risks of the activity was not rejected. The option for the practice of crime of economic nature is a rational and individual one, with or without the influence of others, in face of the perception of costs and benefits such as those made by individuals in relation to others decisions of economic nature. The offenders make individual decisions when the results of criminal action fulfill their interest well or better than the collective action. The relation crime-unemployment did not prove to be so strong in this research, since the majority of the respondents were working when the practice of crime happened. The association of criminality with low level of education was confirmed; the majority of respondents have got only Educação Fundamental (first to four grades), what suggests that high levels of education and better jobs (well payment) can restrict or to retrain the criminality. We observed that more audacious criminal practices besides high levels of organization and planning are essential requisites to these tasks. The principal crime realized were: robbery deal in drugs, fraud, armed-robbery, abduction and extortion that the majority were realized by white young men from the State of Paraná, member of a religious community and having a family. The choice of the type of crime to be realized and the victims, was determined in function of material interest and possible earnings. The main personal motivation to act illegally vis-à-vis to legal was: the induction of friends, the greediness, to maintain the vice, the inconsequence and the wish of adventure, the difficult of money and the idea of easy earnings. The main factors of failure were: the informer, the police's action and their own failure; though, the failure do not refer to the punishment, but to the economic gains not reached. The research revealed that for most of respondents the illegal activity results in some degree of success and for a significant number the economic return was the expected, what justify the great number of relapsing. Finally, for the majority of them the Justice System was considered as insufficient to impede the criminal activity. / O objetivo deste trabalho consiste na análise do crime econômico no Paraná por meio de um estudo de caso nas Penitenciárias Central de Piraquara (PCP), Estadual de Piraquara (PEP) e Feminina de Piraquara (PFP), a partir de dados primários obtidos via aplicação de questionários/entrevistas a réus já julgados e condenados por crimes econômicos. Como corolário deste estudo, não se rejeitou a hipótese de que os criminosos migraram para as atividades ilegais na esperança de os ganhos esperados superassem os riscos da atividade. A opção pela prática do crime de natureza econômica é uma decisão individual tomada racionalmente, com ou sem influências de terceiros, em face da percepção de custos e benefícios, assim como os indivíduos fazem em relação a outras decisões de natureza econômica. Os criminosos agem individualmente quando os resultados da ação criminosa servem aos seus interesses tão bem, ou melhor, que a ação coletiva. A relação crime-desemprego não se constatou tão fortemente neste estudo, pois a maioria dos entrevistados estava trabalhando na época da prática do crime. A associação da criminalidade com o baixo nível de escolaridade foi confirmada, porquanto a maioria dos entrevistados possuía até o 1o grau, o que sugere que maiores níveis educacionais e melhores empregos (com maiores remunerações) podem vir a coibir e/ou tolher a criminalidade. Observou-se que práticas criminosas mais audaciosas e com maior nível de organização e planejamento fazem da educação um requisito essencial para execução de suas tarefas. Os principais crimes econômicos cometidos foram: roubo, latrocínio, tráfico de drogas, furto, estelionato, seqüestro e extorsão, concentrados na sua maioria nos homens brancos, paranaenses, jovens, tendo religião e família. A escolha do tipo de crime a ser praticado, bem como suas vítimas, foi determinado em função do interesse material e da possível renda auferida. Os fatores motivacionais que levaram o indivíduo a atuar no setor ilegal vis-à-vis o setor legal foram: a indução de "amigos", a cobiça/ambição/ganância, manter o sustento do vício, a inconseqüência e desejo de aventura, a dificuldade financeira e a idéia do ganho fácil. Os principais fatores que levaram ao insucesso foram: o dedo-duro (alcagüete), a ação da polícia e a falha própria - descuido, contudo o insucesso citado não se refere à punibilidade, e sim ao retorno econômico não alcançado. A pesquisa revelou que para a maioria dos entrevistados a atividade ilegal resultou em algum grau de sucesso e para um número significativo o retorno econômico foi o esperado, o que justifica o alto índice de reincidentes. Finalmente, o Sistema de Justiça foi considerado, pela maioria, como ineficiente para coibir a atividade criminosa.

Dynamics of carbon and phosphorus flows in arbuscular mycorrhizal symbiosis Mgr. Tereza Konvalinková (doctoral thesis) Abstract Arbuscular mycorrhizal fungi (AMF) are widespread and highly specialized root symbionts, which gain all of their carbon (C) from the hosts, supplying plants with mineral nutrients (particularly with phosphorus, P) in return. This thesis focuses on the size and flexibility of C and P flows in arbuscular mycorrhiza in relation to environmental conditions, in particular to light and P availability. The indications that the symbiotic flows are regulated actively by both partners are discussed. The main findings are presented as a compilation of separate scientific works (two research articles, one review and one book section). A glasshouse experiment has shown that both mycorrhizal benefits and mycorrhizal colonization of medic (Medicago truncatula) by an AMF species (R. irregularis) decline along the gradient of decreasing light intensity. Interestingly, morphological adaptation of medic to the long-term light deprivation was boosted by mycorrhiza, probably because of C demand of AMF and due to the improved nutrition of the mycorrhizal plants. On the other hand, sudden 6-day shading caused rapid decline of shoot P content of mycorrhizal plants, accompanied with the accumulation of P...
