This thesis is focused on the area of automated data mining. The aim of this thesis is a description of the area of automated data mining, creation of a design of an automated data mining tasks creation process for verification of set domain knowledge and new knowledge search, and also an implementation of verification of set domain knowledge of attribute dependency type influence with search space adjustments. The implementation language is the LMCL language that enables usage of the LISp-Miner system's functionality in an automated way. These data analyses were performed on data from air pollution monitoring. The design and implementation were successful and the created scripts could be used (with some manual changes in initial parameters) for analyses of another dataset as well.

This thesis deals with the development of mining and mining colonies in the Ostrava region and also deals with the interpretation of interviews with miners performing their profession in the Ostrava-Karviná mining district between years 1950 and 1994. It focuses not only on the development of the environment and mining conditions in the Ostrava region, but also reasons and motivations for choosing a demanding and often life-threatening profession, as mining is. The thesis is produced using inductive method, where the processes at the individual level apply to wider groups. Such processing allows me to process interviews with witnesses alongside traditional written sources. The finding of the thesis is the fact that there are three main motives for the choosing of mining profession, which are family tradition, the possibility of not participating in two-year compulsory military training and last but not least, the above-standard wage. The thesis offers another view on how workers in socialist Czechoslovakia lived.

No. of bitstreams: 1 Leandro Tavares2.pdf: 1287442 bytes, checksum: 7f5aa84748d1a824abe72b2b6940ffe2 (MD5) Previous issue date: 2014-09-09 / The work analyzes the media in the context of the Internet and outlines new methodologies for the study area in filtering meanings in the scientific realm of information flows from social networks, news media or any other device that allows storage and retrieval of structured information and unstructured. In an attempt to reflect on the ways that these information flows and develop mainly in the volume produced, the project scales the fields of meanings that this relationship appears in the theories and practices of research. The aim of this study is to contextualize the media area within a changing and dynamic reality that is the environment of the internet and make parallel before the applications already successful in other areas. With the method of case study three cases were analyzed under two conceptual keys to Web Sphere Analysis and the Web Science reflecting the opposing information systems in the discursive and structural aspect. This way observes what the Media has earned in order to view its objects of study in the environment of internet networks for these prospects. The research result shows that it is a challenge to the researcher Media seek new learning, but the feedback information in a collaborative environment that the Internet presents is fertile ground for research path, for data modeling wins analytical corpus when the set of tools promoted and driven by technology allows isolating contents and allows deepening the meanings and relationships. / O trabalho desenvolvido analisa a Comunicação Social no contexto da internet e delineia novas metodologias de estudo para a área na filtragem de significados no âmbito científico dos fluxos de informação das redes sociais, mídias de notícias ou qualquer outro dispositivo que permita armazenamento e acesso a informação estruturada e não estruturada. No intento de uma reflexão sobre os caminhos, que estes fluxos de informação se desenvolvem e principalmente no volume produzido, o projeto dimensiona os campos de significados que tal relação se configura nas teorias e práticas de pesquisa. O objetivo geral deste trabalho é contextualizar a área da Comunicação Social dentro de uma realidade mutável e dinâmica que é o ambiente da internet e fazer paralelos perante as aplicações já sucedidas por outras áreas. Com o método de estudo de caso foram analisados três casos sob duas chaves conceituais a Web Sphere Analysis e a Web Science refletindo os sistemas de informação contrapostos no quesito discursivo e estrutural. Assim se busca observar qual ganho a Comunicação Social tem no modo de visualizar seus objetos de estudo no ambiente das internet por essas perspectivas. O resultado da pesquisa mostra que é um desafio para o pesquisador da Comunicação Social buscar novas aprendizagens, mas a retroalimentação de informação no ambiente colaborativo que a internet apresenta é um caminho fértil para pesquisa, pois a modelagem de dados ganha corpus analítico quando o conjunto de ferramentas promovido e impulsionado pela tecnologia permite isolar conteúdos e possibilita aprofundamento dos significados e suas relações.

Today, agile development is broadly used within both small and large organizations worldwide. Transitioning to agile development in a large organization is a complex task that requires support from everyone in it. The Scaled Agile Framework (SAFe) is a framework meant to help integrate agile development within all parts of an organization. Regularly conducted assessments of how well an organization has integrated agile development can be a way to make sure the transition is happening as intended. These kinds of assessments are often called agile maturity assessments. SAFe includes such an assessment, but since the assessment is based on thoughts and reflections from members in the organization, doing the assessment can be difficult and may give unreliable results. This study aims to explore one way to support the assessment with objective data by generating visualizations of issue tracking data extracted from Jira and Github. The Inductive visual Miner, a plugin in the process mining software ProM, was used for the visualizations. A case study was conducted at the IT department of the Swedish Tax Agency. A slightly modified version of the methodology called the PM2 methodology was used to conduct the study. The modified methodology included six stages; a planning stage, a data extraction stage, a data processing stage, a mining and analysis stage, an evaluation stage and lastly, an improvement stage where an attempt was made to improve the visualizations based on the analysis and the evaluation. The planning stage was used to gain information about the work processes in the organization and what kind of data that may exist in the chosen data sources. A set of goal questions connected to the agile maturity assessment were generated, which the visualizations were expected to provide answers to. Data from six teams were then used to generate the visualizations. At first, the visualizations were explored and later evaluated in collaboration with the SCRUM-master in each team. The results in this study show that visualizations generated from issue tracking data using the Inductive visual Miner can be used to answer questions about time and order of events that are related to the agile maturity assessment within SAFe. However, additional analysis and reflections are needed to draw conclusions about the agile maturity from the information obtained from the visualizations. A set of requirements for the data used to generate this kind of visualizations is also proposed. The requirements were based on the results from all stages. / Agil utveckling används idag flitigt inom både små och stora organisationer över hela världen. Att gå över till agil utveckling i en stor organisation är en komplex uppgift som kräver stöd från alla inom den. Scaled Agile Framework (SAFe) är ett ramverk avsett att göra det lättare att integrera agil utveckling inom alla delar av en organisation. Regelbundet genomförda utvärderingar av en organisations användning av agil utveckling kan vara ett sätt att se till att övergången sker som planerat. Dessa utvärderingar kallas ofta agila mognadsmätningar. I SAFe ingår en sådan utvärdering, men eftersom utvärderingen baseras på tankar och reflektioner från medlemmar i organisationen kan det vara komplicerat att utföra utvärderingen och den kan ge icke pålitliga resultat. Syftet med denna studie är att utforska ett sätt att stödja den agila mognadsmätningen med objektiv data genom att generera visualiseringar av ärendehanteringsdata som extraherats från Jira och Github. En plugin kallad Inductive visual Miner i process mining-verktyget ProM används för denna visualisering. En fallstudie genomfördes på Skatteverkets IT-avdelning. En något modifierad version av metoden kallad PM2 -metoden användes för att genomföra studien. Den modifierade metoden inkluderade sex steg; ett planeringsskede, ett datautvinningsskede, ett databearbetningsskede, ett process mining- och analysskede, ett utvärderingsskede och slutligen ett förbättringsskede där ett försök till att förbättra visualiseringarna utifrån analysen och utvärderingen genomfördes. Planeringsstadiet användes för att få information om arbetsprocesserna i organisationen och vilken typ av data som kan finnas i de valda datakällorna. En uppsättning målfrågor kopplade till den agila mognadsmätningen formulerades. Detta var frågor som visualiseringarna förväntades ge svar på. Data från sex team användes sedan för att generera visualiseringarna. Visualiseringarna undersöktes först noggrant och utvärderades sedan i samarbete med SCRUM-mastern i varje team. Resultaten i denna studie visar att visualiseringar genererade från ärendehanteringdata med hjälp av verktyget Inductive visual Miner kan användas för att svara på frågor om tid och ordning av händelser i arbetsprocessen, som är relaterade till den agila mognadsmätningen inom SAFe. Ytterligare analyser och reflektioner behövs dock för att dra slutsatser om den agila mognaden utifrån informationen som erhålls från visualiseringarna. En uppsättning krav för den data som ska användas för att generera denna typ av visualiseringar föreslås också. Dessa krav är baserade på resultaten från alla steg i metoden.

The impact of a mandatory Part 48 training program on the health and safety knowledge level of newly employed inexperienced miners in Texas was studied. Part 48 training was defined by compliance with Mine Safety and Health Administration's (MSHA) mandatory health and safety training requirements. A two-group pretest, posttest research design was utilized. Group one individuals were newly employed inexperienced persons who received mandatory Part 48 training in accordance with MSHA guidelines. Group two subjects were newly employed inexperienced persons who worked for companies that were exempt from conducting a Part 48 training program. MSHA's health and safety knowledge inventory was utilized. A significant difference was found in the health and safety training program when compared with individuals who did not receive the training . A significant difference was also found in the posttest scores for eight of the ten subject areas of the MSHA health and safety knowledge inventory for persons who completed a Part 48 training program when compared to persons who did not receive the training . Analysis of gain scores resulted in significant differences in the same subject areas indicated by posttest scores. It was concluded that MSHA Part 48 did have a significant impact on the health and safety knowledge level of newly employed inexperienced miners. Additional implications noted relate to the impact of a Part 48 training program on accidents, productivity, absenteeism, turnover, job satisfaction and management styles; role of MSHA in miner training; development of new training materials; methods of training; and the evaluation of health and safety training programs.

It is examining the social construction of the idea of sustainable development and the importance that this issue has acquired social-environmental agenda in communication, especially to understand the transformations in the Brazilian advertising, and in particular, the time that the socioenvironmental commitment became the focus of construction of identity. Are studied regimes of visibility established considering the before and after the change of visual identity of the company, which was implanted in 2007. The corpus of work shall consist of advertisements in print media by mining between 1999 and 2011. Analyses verb-visuals to be developed will be based in plastic-semiotic discursive from Diana and Vicente Barros Pietroforte, as well as the social theory of discourse, from Norman Fairclough, in the communication contracts, as Patrick Charadeau points and the discursive theories from Ernesto Laclau, focusing the research on constructions of sense of environmental responsibility within a totalizing ideological discourse which selects this theme as a standard. From theorical considerations from Laymert Garcia dos Santos, Anthony Giddens, Luc Ferry and, in particular, Joan Martínez Alier, we will discuss the green discuss, the figures of the different currents of environmentalism and its implications in Brazilian advertising / Esta pesquisa investiga, nos respectivos contratos comunicacionais, os agendamentos temáticos da publicidade da mineradora Vale no estado do Maranhão. Trata-se de examinar a construção social da ideia de desenvolvimento sustentável e a importância que a temática socioambiental vem adquirindo na agenda comunicacional, sobretudo para compreender as transformações ocorridas na publicidade brasileira, e, em especial, o momento em que o compromisso socioambiental tornou-se o foco da construção identitária. São estudados os regimes de visibilidade estabelecidos considerando-se o antes e o depois da alteração da identidade visual da empresa, que se implantou em 2007. O corpus do trabalho será constituído pelos anúncios publicados pela mineradora na mídia impressa entre 1999 e 2011. As análises verbi-visuais a serem desenvolvidas embasar-se-ão na semiótica plástico-discursiva a partir de Diana Barros e Vicente Pietroforte, assim como na teoria social do discurso, de Norman Fairclough, nos contratos comunicacionais, conforme aponta Patrick Charaudeau e nas teorias discursivas de Ernesto Laclau, centrando a investigação nas construções dos sentidos de responsabilidade socioambiental dentro de um discurso ideológico totalizante que elege esse tema como estandarte. A partir de reflexões teóricas de Laymert Garcia dos Santos, Anthony Giddens, Luc Ferry e, em especial, Joan Martínez Alier, discutiremos a questão verde, as figuras das diferentes correntes do ambientalismo e suas implicações na propaganda brasileira

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Pretendemos com esse trabalho analisar as relações entre as Mineradoras e a sociedade civil local das regiões mineradoras, por meio principalmente da Teoria da Dependência. Tentamos refletir sobre os efeitos da atividade minério-exportadora nas populações locais e as maneiras de manutenção dessa ordem social. O estudo pode ser dividido em dois que se interrelacionam: 1) no primeiro, empreendemos uma discussão sobre o subdesenvolvimento, a dependência e a mineração num país semiperiférico como o Brasil; 2) no segundo, analisamos, especificamente, a conjuntura da instalação da Mina Apolo da Vale. Esta parte da pesquisa está baseada no trabalho de campo e na análise das entrevistas com os envolvidos no debate sobre a Mina Apolo e o Parque Nacional do Gandarela. Ao buscarmos nas relações de classe da região as razões para a manutenção da atividade mineira-exportadora, intentamos discutir o tipo de desenvolvimento que a mineração engendra. Partimos da hipótese de que são inúmeros os danos causados pela mineração à sociedade civil local, principalmente a longo e médio prazo. A população local e as classes populares não mobilizam um discurso contra-hegemônico, ou mesmo questionador, de ampla aceitação na sociedade civil local porque o discurso do desenvolvimento minerador e a dependência econômica da região frente à mineração desmobilizam os movimentos críticos e contrários às mineradoras. Esta dependência econômica é traduzida em dependência sócio-política. / We intend at this work to show the class relations between miner companies and local civil society, primarily through the Dependency Theory. We try to reflect about the social effects of the ore exports in local populations of the mining regions and the ways of maintaining this social order. Sometimes, we focused our analysis specifically in the city of Caeté where mitigates the Apolo Project of Vale SA. Our hypothesis is that there are numerous damage caused by mining to the local civil society. The local population and the working classes do not mobilize a counter-hegemonic discourse, or even questioning, wide accepted in the local community because of the discourse of progress and development and the economic dependency of the region to the mining demobilize the opposite movements to mining.
