Pela primeira vez incêndios florestais são identificados em uma associação de fácies contendo a Flora Dicroidium nos sedimentos avermelhados do Triássico Médio (Ladiniano) na parte sul da Bacia do Paraná (Formação Santa Maria, Rio Grande do Sul). A extensão geográfica dessa assembleia de plantas foi, assim, estendida no Gondwana brasileiro. As análises por petrografia orgânica, fluorescência, microscopia eletrônica de varredura (MEV) e microscopia eletrônica de varredura (tipo field emission gun - MEV-FEG) revelaram a presença recorrente de carvão vegetal (charcoal) na sucessão vertical de fácies relacionadas a um modelo deposicional de fluxos efêmeros de baixa densidade do tipo inunditos. O carvão microscópico (micro-charcoal) ocorre como fragmentos comuns em diferentes fácies, enquanto que o carvão vegetal macroscópico (macro-charcoal) é representado por espécimes tridimensionais de lenhos atribuídos a gimnospermas (Pinaceae?) e por fragmentos achatados, finos e alongados atribuídos a pteridospermas (rachises de Dicroidium?) Os valores médios de reflectância da inertinita entre 2,80-6,61 %Ro medidos nos fragmentos de macro-charcoal evidenciaram processos de queima de alta temperatura, envolvendo tanto incêndios na copa quanto na interface copa-superfície. A recorrência de fragmentos queimados em várias fácies do perfil estudado indica a ocorrência de incêndios regionais que afetaram tanto as comunidades meso-xerófilas distais quanto às associações proximais higro- mesófilas, compostas majoritariamente por espécimes da Flora Dicroidium. A integração dos resultados obtidos a partir das múltiplas análises dos fragmentos de charcoal é consistente com um teor de oxigênio atmosférico superior a 20%. / For the first time wildfires are reported from an association of different facies containing a Dicroidium flora from the Middle Triassic (Ladinian) red beds in the southern part of the Paraná Basin (Santa Maria Formation, Rio Grande do Sul state). The geographical extension of the Dicroidium plant assemblage has thus been extended in the Brazilian Gondwana. Analyses through petrography, fluorescence microscopy, scanning (SEM) and field emission gun scanning electron microscopy (FEG-SEM) revealed recurrent charcoal presence in a vertical facies succession of depositional cycles related to ephemeral prograding low density flows. Microscopic charcoal occurs as common fragments within different facies whereas macroscopic charcoal is represented by tridimensional wood specimens assigned to gymnosperms (Pinaceae?) and by flattened, thin, elongated remains assigned to pteridospermophytes (rachises of Dicroidium?). Average reflectance values between 2.80-6.61 %Ro measured in the macro-charcoals evidenced burning processes of high temperature, involving fires both in the crown and in the crown-surface interface. The recurrence of charcoal in several facies of the studied profile indicates regional wildfires, which affected hinterland, meso-xerophyllous coniferous assemblages and marginal hygro-mesophyllous Dicroidium-like assemblages. The integration of results obtained from the multiple charcoal analyses is consistent with atmospheric oxygen content higher than 20%.

O objetivo deste trabalho é analisar influências do Fit Estratégico para o alcance de acordos em negociações de Fusões e Aquisições (F&A). A metodologia envolveu pesquisa qualitativa com suporte quantitativo para desenvolver estrutura analítica que integrasse elementos de F&A e Negociação, permitindo identificar e avaliar 115 variáveis em 20 casos reais de negociações de F&As, 10 com Acordo Alcançado e 10 com Acordo Não Alcançado. Embora com limitações, o estudo alcançou os objetivos propostos identificando quatro Macrorrelações de Influência (MRI) principais: Existência de Fit Estratégico influencia positivamente a chance de acordo, através das Sinergias, assim como sua ausência influencia negativamente; Riscos e Impedimentos integram a Equação de Valor para o Comprador, quando eles ameaçam a captura de valor, podem inviabilizar a chance de acordo; Pressões Indutoras influenciam positivamente a chance de acordos em operações de F&As; e, Interesses Críticos Convergentes são condição precedente para o alcance de acordos em operações de F&As. Esta dissertação contribui para o desenvolvimento de uma visão integrada entre F&A e Negociação, permitindo uma conduta mais consciente, consistente e estratégica para alcançar acordos. Atenção particular é dada à MRI que envolve Fit Estratégico. Além de demonstrar ser forte fator de influência (82% dos casos com Fit atingiram acordo), a estrutura analítica quantitativa utilizada se revelou robusta (os resultados observados nos 20 casos confirmam estudo anterior com 218 casos de Shelton, 1988), apresentando aptidão para ser convertida em ferramenta de suporte à decisão, já que permite avaliar potencial sinérgico entre empresas e nichos de mercado. / The objective of this work is to analyze the influences of Strategic Fit in order to reach agreements in Mergers and Acquisitions (M&A) negotiations. The method involved a qualitative research with quantitative support to develop an analytical framework that integrates elements of M&A and Negotiation, allowing to identify and evaluate 115 variables in 20 actual cases of M&A negotiations of Which 10 Reached a Deal, and 10 Did Not Reach a Deal. Although with limitations, the study achieved its proposed objectives identifying four macro-relations of influence (MRI): Strategic Fit presence positively influences the chance of an agreement, through Synergies and its absence has a negatively influence; Risks and Impediments are part of the Value Equation to the Buyer, when threatening the capture of value they can prevent the chance of agreement; Inducing Pressures positively influences the chance of agreements in M&A transactions; and Critical Converging Interests is a pre-condition to reach agreements in M&A operations. This dissertation contributes to the development of an integrated view between M&A and Negotiation, enabling a more cognizant, consistent and strategic behavior in order to reach agreements. Particular attention is given to the MRI that involves Strategic Fit, as it proved a strong influencing factor (82% of cases with Strategic Fit reached an agreement). As well, the quantitative analytical framework used showed to be robust (results in the 20 cases studied in here confirmed a previous study by Shelton in 1988 of 218 cases) indicating potential to become a decision-supporting tool, since it allows the synergy potential evaluation between companies and market niches.

In this sense, environmental education proposes the construction of a responsible citizenship, stimulating fairer interactions between human beings and the other beings that inhabit the Planet, for the construction of a present and a sustainable, healthy and socially fair fuure. The objective of this paper was to investigate the presence of the environmental theme in public schools in Amazonas under the Science in School Program (PCE), an initiative of the Foundation for Research Support in Amazonas (FAPEAM), which aims to stimulate the scientific literacy of basic education of public schools and the involvement of their teachers with scientific practice. A total of 61 projects developed in 2014 and 2015 in public schools in the capital of Manaus and in nine municipalities (Atalaia do Norte, Borba, Coari, Iranduba, Itacoatiara, Nhamundá, Parintins, Tabatinga and Tefé) were analyzed in which was brought the theme of environment as their object of research. The results presented here were obtained from the analysis of edicts, decisions, projects and their respective reports. It could be noticed that this theme is not a priority in the projects developed, since only 8% of them, in the years of 2014 and 2015, brought this approach as a research theme. The most worked topics were garbage (28%), recycling (21%), environmental issues (16%), water (10%) and composting (10%). The majority of these projects were developed in Manaus (62%), in schools administered by the State Department of Education - SEDUC (83%) and with high school students (56%). Most of these projects were linked to the disciplines of Biology (26%), Geography (26%) and Science (19%). The main means used to carry out the activities were: bibliographic survey, workshops, collections and videos. The teachers coordinating the projects are mostly female (75%). All the professors have completed higher education, of which 31% have a postgraduate level of specialization (Lato Sensu) and 9% have a master's degree. Among the three politicalpedagogical macro-trends of Environmental Education, the pragmatic macro-trend was the one that stood out among the projects analyzed, followed by conservationist and critical. / Acreditamos que educação constitui-se como uma poderosa ferramenta de intervenção no mundo para a construção de novos conceitos e consequente mudança de hábitos. Neste sentido, a educação ambiental propõe a construção de uma cidadania responsável, estimulando interações mais justas entre os seres humanos e os demais seres que habitam o Planeta, para a construção de um presente e um futuro sustentável, sadio e socialmente justo. O objetivo deste trabalho foi averiguar a presença da temática ambiental nas escolas públicas do Amazonas no âmbito do Programa Ciência na Escola - PCE, que é uma iniciativa da Fundação de Amparo à Pesquisa no Amazonas-FAPEAM, que objetiva estimular a alfabetização cientifica de alunos da educação básica de escolas públicas e o envolvimento de seus professores com a prática científica. Foram analisados 61 projetos desenvolvidos nos anos de 2014 e 2015 em escolas públicas da capital Manaus e em nove municípios (Atalaia do Norte, Borba, Coari, Iranduba, Itacoatiara, Nhamundá, Parintins, Tabatinga e Tefé), que traziam a temática ambiental como objeto de pesquisa. Os resultados aqui apresentados foram obtidos a partir da análise de editais, decisões, projetos e seus respectivos relatórios. Pôde-se observar que esta temática não é prioridade nos projetos desenvolvidos, pois somente 8% deles, nos anos de 2014 e 2015, trouxeram esta abordagem como tema de pesquisa. As temáticas mais trabalhadas foram lixo (28%), reciclagem (21%), questões ambientais (16%), água (10%) e compostagem (10%). A grande maioria destes projetos foi desenvolvida em Manaus (62%), em escolas administradas pela Secretaria de Estado de Educação - SEDUC (83%) e com alunos do ensino médio (56%). A maior parte destes projetos estava vinculada às disciplinas de Biologia (26%), Geografia (26%) e Ciências (19%). Os principais meios utilizados para realização das atividades foram: levantamento bibliográfico, oficinas, coletas e vídeos. Os professores coordenadores dos projetos são em sua maioria do sexo feminino (75%). Todos os professores possuem formação superior completa, dos quais 31% possuem pós-graduação em nível de especialização (Lato Sensu) e 9% possuem titulação de mestre. Dentre as três macrotendências políticopedagógicas de Educação Ambiental, a macrotendência pragmática foi a que se destacou entre os projetos analisados, seguida da conservacionista e crítica.

Objetivando-se estudar o efeito da suplementação mineral no desenvolvimento reprodutivo de bubalinos do desmame aos 24 meses de idade, utilizaram-se 110 búfalos, distribuídos em três experimentos (A, B e C), que foram criados em três propriedades (GA, GB e GC) no Estado do Pará. Os experimentos A e B foram realizados em áreas de terra firme com pastagens cultivadas (Brachiaria brizantha cv. Marandu) em manejos rotacionado e extensivo, respectivamente, com capacidade de suporte e perfil nutricional da forragem, semelhantes. O experimento C foi desenvolvido em áreas de várzea na Ilha de Marajó, com pastagens nativas constituídas, principalmente, por Panicum sp, Axonopus sp e Paspalum sp. Em todas as propriedades dividiram-se os animais em dois grupos (experimento A: GA1 e GA2, experimento B: GB1 e GB2, e experimento C: GC1 e GC2) que foram mantidos a pasto com diferentes suplementações minerais. Os animais foram pesados a cada 28 dias e receberam distintos suplementos minerais: grupos GA2 e GB2 mistura mineral, a ser testada, indicada para búfalos; grupos GA1 e GB1 - misturas minerais utilizadas rotineiramente na fazenda e recomendadas para bovinos; GC1 animais não suplementados e GC2 mistura mineral indicada para búfalos criados em áreas de várzea com águas salobras. As sobras da mistura mineral foram recolhidas semanalmente para se calcular o consumo real da mesma. A cada 56 dias as circunferências escrotais, comprimentos, larguras e espessuras dos testículos foram mensurados, como também foi avaliada a disponibilidade quali-quantitativa da forragem. Aos 22 meses de idade, 77 búfalos foram submetidos a colheitas de sêmen semanais, nos meses de maio e junho de 2005 (n = 616 amostras de sêmen), através de eletroejaculação para se analisar as características físico-morfológicas do sêmen. No plasma seminal foram, determinadas as concentrações de Ca, P, Mg, Cu, Co, Fe, Zn e Mn. Após 14 meses de estudos constatou-se que tanto os animais do grupo GA2 como os do GB2 obtiveram um maior ganho de peso médio diário (p<0,0001). O grupo GA1 consumiu uma maior (p<0,0001) quantidade de mistura mineral, enquanto que para os grupos GB1 e GB2 não houve diferença significativa. As medidas testiculares do grupo GA2 foram significativamente maiores, ao final do estudo, do que as do grupo GA1, demonstrando com isso um efeito da suplementação mineral sobre estas variáveis. Para o grupo GB2 a espessura, a largura e o volume testicular foram significativamente maiores. As demais medidas não sofreram variações significativas. No experimento C não houve variação entre o peso e o ganho de peso para ambos os grupos. Isso provavelmente esta relacionado ao baixo consumo de mistura mineral pelo grupo GC2. Essa pequena diferença do peso entre os grupos GC1 e GC2 foi acompanhada por uma diferença não significativa nas medidas testiculares dos grupos. Deduz-se que devido as altas correlações positivas entre a circunferência escrotal (CE), o peso corporal e demais medidas dos testículos, a CE possa ser utilizada para predizer o tamanho testicular. Conclui-se ainda que a suplementação mineral testada exerceu efeito positivo sobre o peso e o ganho de peso médio diário dos animais dos experimentos A e B. Evidenciou-se médias significativamente maiores para as características físicas do sêmen dos animais que receberam a suplementação mineral testada (GA2) com exceção da concentração espermática. Para as características morfológicas do ejaculado, observou-se que os animais do grupo GA1 apresentaram médias significativamente maiores para o número total de espermatozóides anormais. Não foram verificadas diferenças significativas nas características físicas e morfológicas do sêmen dos grupos GB1 e GB2, com exceção do volume do ejaculado e da motilidade progressiva que foram significativamente maiores para os animais do grupo GB2. Observaram-se correlações significativas, porém baixas, entre a CE a algumas características do ejaculado. Conclui-se, portanto que houve influência da suplementação mineral nas características físicas e morfológicas do sêmen dos animais do experimento A, com melhores resultados para o grupo GA2, que consumiram a suplementação mineral testada; constatou-se, ainda, uma tendência de uma melhor qualidade no sêmen dos animais do grupo GB2. Foi possível averiguar que não houve diferença significativa para os constituintes macro e microminerais do plasma seminal de búfalos jovens, criados em pastejo rotacionado, exceto para os níveis de manganês que foram significativamente maiores para os animais do grupo GA2. Obtiveram-se os seguintes valores para Ca (14,32 ± 6,40 mg/dl), P (3,86 ± 3,30 mg/dl), Mg (11,64 ± 7,02 mg/dl), Zn (4,23 ± 1,35 &mu;g/ml), Fe (8,23 ± 2,38 &mu;g/ml), Cu (0,17 ± 0,07 &mu;g/ml), Co (0,06 ± 0,04 &mu;g/ml) e Mn (0,08 ± &mu;0,06 g/ml) contidos no plasma seminal de búfalos criados em pastejo rotacionado. Os animais do grupo GB2 apresentaram maiores níveis de fósforo e cobalto do que os do grupo GB1, que por sua vez obtiveram maiores teores de manganês. Encontraram-se os seguintes valores Ca (12,16 ± 2,97 mg/dl), P (4,01 ± 4,46 mg/dl), Mg (11,37 ± 6,48 mg/dl), Zn (4,02 ± 1,39 &mu;g/ml), Fe (6,73 ± 1,80 &mu;g/ml), Cu (0,07 ± 0,03 &mu;g/ml), Co (0,14 ± 0,06 &mu;g/ml) e Mn (0,17 ± 0,11 &mu;g/ml) contidos no plasma seminal de búfalos criados em sistema extensivo. Muito embora alguns minerais tenham apresentado correlações significativas com algumas características do ejaculado, essas foram baixas. Portanto não se observou uma variação quali-quantitativa nas concentrações físicas e morfológicas do ejaculado de búfalos jovens criados em pastejo rotacionado e sistema extensivo, em função da concentração de minerais no plasma seminal. / To objectify the study of the effect of mineral supplementation in the reproductive development of buffaloes of wean in the 24 months of age, were used 110 buffaloes, distributed in three experiments (A, B e C) created in three farms (GA, GB e GC) in the Para State. The experiments A e B were realized in areas of firm soil with cultivated pasture (Brachiaria brizantha cv. Marandu) in rotational and extensive management, respectively, with similar capacity of support and nutritional profile of the forage. The experiment C was developed in tilled plain areas in Marajo Island, with native pasture basically formed by Panicum sp, Axonopus sp e Paspalum sp. In all farms the animals were divided in two groups (A: GA1 e GA2 experiment, B: GB1 e GB2 experiment, and C: GC1 e GC2 experiment) which were maintained in the pasture with different mineral supplements. The animals were pondered in each 28 days and received different mineral supplements: GA2 and GB2 groups mineral blend, to be tested, indicated to buffaloes; GA1 and GB1 groups mineral blend used in a regular procedure in the farm and recommended to bovines; GC1 group not supplemented animals and GC2 group mineral blend indicated to buffaloes created in tilled plain areas with salutary waters. The remaining mineral blends were collected weekly to calculate the real use of the blends. In each 56 days the scrotal circumferences, lengths and widths of the testis were measured, and was evaluated the availablebility of the quality and the quantity of the forage, as well. In the 22 month of age, 77 buffaloes were submitted to weekly semen collects, in May and June of 2005 (n = 616 semen samples), trough electroejaculation to analyze the semen physic and morphologic characteristics. In the seminal plasma were determined the Ca, P, Mg, Cu, Co, Fe, Zn e Mn concentration. After 14 months of research both animal groups (GA2 and GB2 groups) got larger diary medium weight gain (p<0,0001). The GA1 group has consumed a larger (p<0,0001) quantity of mineral blend, although to the GB1 and GB2 groups there wasnt any significative difference. The testicular measurements of GA2 group were significatively larger, at the end of the research, as the GA1 group, proving that the effects of mineral supplement on these variants. To the GB2 group the thickness, the width and the testicular volume were significatively larger. The others measurements havent significant variations. In the C experiment there wasnt any variation between the weight and gain of weight to both groups. This is probably connected to low use of mineral blend by GC2 group. This insignificant difference of the weight between GC1 and GC2 group was followed by an insignificant difference in the testicular measurements of the groups. Due to high positive correlations between the scrotal circumference (SC), the weight of the body e others measurements, deduce that the SC can be used to predict the testicular size. It can be concluded, as well, that the tested mineral supplement carried out a positive effect on the weight and the gain of diary medium weight of the animals in the experiments A and B. The research proved significant bigger mean rates to the physical characteristics of the animals semen that received the tested mineral supplement (GA2) with exception of spermatic concentration. To the morphological characteristics of semen, it observed that the GA1 animal group showed significant mean rates larger to the total number of abnormal sperm. Significant differences werent noted in the physical and morphological characteristics of the semen of GB1 and GB2 groups, with exception of the volume of the semen and of the motility progressive which were significatively larger to the animals of GB2 group. Significant, but low correlations between the SC and some characteristics of the semen were observed. Consequently, it can be concluded, there were influence of the mineral supplement in the physical and morphological characteristics of the animals semen of A experiment, with better results to GA2 group , that consumed the tested mineral supplement; a tendency of a better quality of the animals semen of the GB2 group animals. Was possible to verify there werent important difference to the macro and micro mineral constituents of the seminal plasma of young buffaloes, created in rotational pasture system, except to the levels of manganese which were significatively larger to the GA2 group animals. The next values were obtained: to Ca (14,32 ± 6,40 mg/dl), P (3,86 ± 3,30 mg/dl), Mg (11,64 ± 7,02 mg/dl), Zn (4,23 ± 1,35 &mu;g/ml), Fe (8,23 ± 2,38 &mu;g/ml), Cu (0,17 ± 0,07 &mu;g/ml), Co (0,06 ± 0,04 &mu;g/ml) e Mn (0,08 ± 0,06 &mu;g/ml) contained in the seminal plasma of the buffaloes created in rotational pasture system. The GB2 group animals introduced larger levels phosphorus and cobalt than the GB1 group, which obtained larger values of manganese. The following values were also discovered: Ca (12,16 ± 2,97 mg/dl), P (4,01 ± 4,46 mg/dl), Mg (11,37 ± 6,48 mg/dl), Zn (4,02 ± 1,39 &mu;g/ml), Fe (6,73 ± 1,80 &mu;g/ml), Cu (0,07 ± 0,03 &mu;g/ml), Co (0,14 ± 0,06 &mu;g/ml) e Mn (0,17 ± 0,11 &mu;g/ml) contained in the seminal plasma of the buffaloes created in extensive system. In spite of some minerals have presented significant correlations with some characteristics of the semen, these ones were lows. Then a variation of the quality and the quantity of physical and morphological concentrations of the semen of young buffaloes created in rotational pasture system and extensive system werent observed.

Foi dada ênfase ao papel exercido pela Secretaria de Administração e Reforma do Estado SARE, escolhida como objeto do estudo de caso por ser responsável por fomentar um novo modo de atuação dos gestores ligados tanto à atividade-fim como à atividade-meio das instituições envolvidas nesse processo. Para tanto, algumas temáticas foram exploradas, tais como: as transformações de suas competências, ajustes na estrutura organizacional e os instrumentos utilizados no processo de implantação dessa mudança na administração pública estadual. De caráter descritivo e explanatório, o trabalho foi elaborado sob a forma de um estudo de caso, delineado a partir da experiência da autora como integrante da equipe técnica da Comissão de Reforma do Estado de Pernambuco. Tomou-se como referência os princípios balizadores do processo de Reforma do Estado, com ênfase no período de 1999 a 2005, tendo em vista a busca da consolidação da administração gerencial, voltada para resultados com foco no cidadão, e na melhoria da prestação dos serviços públicos. Assim, buscou-se fazer um levantamento teórico-conceitual das estruturas organizacionais e do processo de Reforma do Estado no mundo, no Brasil e em Pernambuco, construindo um arcabouço explicativo de como se deu a implantação desse novo modelo de atuação, tanto em termos conceituais como dos desenhos que foram efetivamente adotados. Como resultado, colocou-se em perspectiva os atores e os instrumentos direcionadores da mudança implementada pelo Governo de Pernambuco, à época. Foi feito um acompanhando da evolução e a metodologia adotada pelo Programa Pernambucano de Modernização da Gestão Pública PROGESTÃO. Destaque deve ser dado, ainda, à articulação prevista para a integração dos sistemas de planejamento, administração e finanças. Ao final, são tecidas considerações acerca da necessidade de se melhor compreender a cultura instalada, de se ampliar os espaços de participação da sociedade nesse processo e de obter comprometimento dos atores envolvidos

The IMRD structure with its constituents Introduction, Method, Results and Discussion is acknowledged as the norm for writing abstracts by most. Researchers need to adhere to the norm in order for their abstracts to function as effective advertisements for their research articles, and students need to comply with the norm should they want their abstracts to serve as connectors to the academic world. The aim of this thesis is to examine to what extent abstracts written in English by Swedish students adhere to the IMRD norm. A total of 40 bachelor’s thesis abstracts in English linguistics and physics were analyzed in terms of macro structure, the inclusion, exclusion and order of the constituent parts, and micro structure, the linguistic realization of the constituents. The results show that the English linguistics and physics abstracts fail to meet the requirements of the IMRD norm on several points. This suggests that the students are either unaware of the important function fulfilled by abstracts or need more guidance and practice. The conclusions are necessarily tentative since further research is required to provide a comprehensive picture, but still, the results suggest that Swedish students’ abstract writing needs to be given higher priority.

Despite the recent decreasing trend of most traditional types of crime, online property crime (OPC), referring to crime committed online with a financial orientation such as online frauds, scams, and phishing, continues to increase. According to the Internet Crime Complaint Center, the number of reported complaints about OPC have increased by approximately sixteen fold from 16,838 cases in 2000 to 288,012 cases in 2015, and referred financial losses have also increased about sixty times from $17.8 million in 2001 to $1 billion in 2015. The increase in OPC might be directly related to advanced online accessibility due to the accelerated progress of information and communication technology (ICT). Since the progress of ICT continues forward and the advanced ICT infrastructure can affect our routine activities more significantly, issues regarding OPC may become more various and prevalent. The present study aims to explore a macro-social criminogenic structure of OPC perpetration. Specifically, this study focused on exploring probable macro-social predictors of OPC rates and examining how effectively these possible macro-social predictors account for variance in OPC perpetration rates. In addition, this study explored possible predictors of macro-level online opportunity structure, which is expected to have a direct relationship with OPC rates. It also examined how much variance in online opportunity structure was explained by the included possible predictors. With these research purposes, the current study analyzed state-level data of the fifty states in the U.S. by applying a partial least square regression (PLSR) approach. The results indicated that predictors related to macro-social economic conditions such as economic inequality, poverty, economic social support, and unemployment had a significant association with OPC. As expected, indicators in the domain of economic inequality predicted greater OPC rates and those in the domain of economic social support were related to lower OPC rates. However, poverty and unemployment predictors were negatively associated with OPC, which is the opposite direction of the relationships between these predictors and traditional street crime. In addition, indicators of online opportunity structure were found to have a significantly positive relationship to OPC as expected. The PLSR model for predicting OPC applied in the current study accounted for approximately 50% of variance in OPC rates across states. For predictors of online opportunity structure, the results indicated that online opportunity was associated with state-level economic and socio-demographic characteristics. States with less poverty, more urban population, and more working age adults were more likely to report more online opportunities. The PLSR model for predicting online opportunity structure explained about 80% of variance in measured online opportunity. These results may imply that some types of macro-social conditions may have an indirect effect on OPC through online opportunity structure as well as their direct effects on OPC. Future study should pay more attention to examining structural relationships of macro-social contexts, online opportunity structure, and OPC to understand macro-level criminogenic mechanism of OPC.

The importance of traffic planning has, throughout the years, been in- creased, providing sustainable developments of traffic and infrastructural investments. The analysis of the current traffic situation and the evalua- tion of the effects of a future investment are crucial for the socio-economic benefits maintenance. These analyses and evaluations are most commonly done using traffic simulation models. One of the main traffic planning aims, nowadays, is to increase the number of public transport users against the number of private car users. This change in mode choice is called transition effect and could be beneficial both from an environmental and socio-economic perspective. This thesis aims to evaluate and improve the macroscopic traffic demand and transition model, used fot the city of Norrköping. Additionally, the thesis investigates if a general transition Logit model can be developed and which parameters are the most important to be included in a modal choice estimation. For the needs of this study, the traffic planning software Visum is used. The travel mode distribution is calculated by Logit models coded in Python-scripts integrated in Visum. Then, a traffic assignment is performed by Visum, computing new travel times as inputs to the Logit model and this iterative procedure continues until the system reaches an equilibrium. The thesis aims for a more reliable prediction of the transition effect by correcting the Python-scripts and estimating the parameters of the Logit model using data from surveys. The study shows that travel times is the most important factor for realistic results generation. However, the data used for the estimation of the Logit model parameters did not include sufficient information of travel times. The travel times had to be calculated, using two different methods, in order to be included in the estimation of new parameters. Although these methods could not provide any positive effects on the transition, they did prove the importance and significance travel time have when developing a traffic model. The result of the study invokes the importance to further develop the method of calculating travel times, when the input data is not sufficient, and shows that the travel time parameters are case specific.

Magister Legum - LLM / The impact of trade policies on the pursuit of gender equality is often ignored. Recognising the link between trade and gender, this dissertation aims to enhance the capacity of policy-makers to mainstream gender in trade policy and to help identify ways for using trade to respond to women's needs in South Africa. In order to meet this objective, it analyses the impacts that trade liberalisation has had on the economy and on gender in general and in South Africa in particular. In addition, it evaluates the impacts on men and women in order to see if trade has contributed to reducing, accentuating or perpetuating gender inequality in South Africa. Findings have confirmed that Trade liberalisation has had both positive and negative impacts on women and men. But, they have also demonstrated that trade liberalisation has affected women and men differently having negative influences on the pursuit of gender equality. The research has, however, concluded that the impact of trade liberalisation on the pursuit of gender equality is influenced by other key factors. As strategy to mainstream gender in trade policies, the research suggests that policy-makers should analyse the implications for women and men of any trade policy before adopting such policy. This analysis would help him/her to see the possible imbalances of the new policy and implement policies and programmes to eradicate them. Also, it will help him/her to identify possible ways for using trade to empower women. The research is based on the idea that the elimination of the existing inequalities will put women at the same stage with men and will, therefore, contribute to women's empowerment in South Africa. / South Africa

Introduction In Senegal, as in many countries, physicians are unevenly distributed. This situation leads to health inequalities, but the solutions adopted to distribute physicians equitably do not give satisfactory results. This situation pushes decision-makers and researchers to look for other solutions such as telemedicine. This technology-based solution is considered to be a good means to improve physician recruitment and retention in underserved areas, thus improving access to healthcare in these areas, but it is still underused in Senegalese health facilities. Objective This study aimed to identify the determinants of the use of telemedicine in Senegal. More specifically, it aimed to identify the individual (micro) and contextual (meso and macro) factors that influence the use of telemedicine in Senegal. Method The study involved mixed methods: a descriptive qualitative study involving individual interviews and a cross-sectional quantitative study involving questionnaires. The first method was used to study the individual (micro) factors such as physicians’ beliefs on the use of telemedicine and physicians’ perception of the impact of telemedicine on their recruitment and retention in underserved areas. It was also used to study the contextual meso (technical, organizational and ethical) and macro (financial, political, legal and socioeconomic) factors that influence the use of telemedicine. The second method was used to study participants’ intention to use telemedicine in their professional activities, another individual (micro) factor. This study included physicians working in public hospitals, those working in district health, and telemedicine projects managers. Qualitative data was collected through individual interviews, transcribed and imported into NVivo 10 where they were coded thematically. Quantitative data was collected by administering questionnaires and analyzed using SPSS 23. Results The results showed that telemedicine could contribute to, but could not guarantee the recruitment and retention of Senegalese physicians in underserved areas. It was found that physicians in Senegal have both positive and negative behavioural, normative and control beliefs that can encourage or discourage them from using telemedicine in their professional practice. The most salient behavioural beliefs were that telemedicine makes experts’ opinions accessible across distances (positive behavioural belief), but could lead to medical errors (negative behavioural belief). The most common normative beliefs were that their patients would most probably approve the use of telemedicine (positive normative belief) while their colleagues working in the public sector might disapprove of it (negative normative belief). The most reported control beliefs were that the use of telemedicine is easy (positive control belief), but could be time-consuming (negative control belief). For physicians in Senegal, the findings also demonstrate that the probability that they will use telemedicine in their professional activities is moderate and influenced by their perceived behavioural control which, in turn, is influenced by their positive and negative control beliefs. Finally, the results demonstrate that many contextual meso (technical, organizational and ethical) and macro (financial, political, legal and socioeconomic) factors influence the use of telemedicine in Senegal. Conclusion The results of this study can inform the choice of telemedicine development strategies. These strategies can help to promote the use of telemedicine in Senegal, which in turn can help to increase physician recruitment and retention in underserved areas, resulting in better access to healthcare and, and as a result improved population health.
