Det här examensarbetet inom lantmäteriteknik och geografisk IT syftar till att identifiera potentiellt förorenade områden i Torsby kommun med hjälp av GIS (geografiska informationssystem). GIS kan lagra, hantera, analysera och visualisera geografisk data. Miljöföroreningar är ett växande globalt problem och kommer framförallt från mänskliga aktiviteter. Föroreningar i form av PFAS (Per- och polyfluorerade alkylsubstanser), metaller och övriga organiska föroreningar utgör betydande risker för både miljön och människors hälsa. Flera av dessa föroreningar är kända som cancerogena och bioackumulerande. Vidare kan de dessutom vara persistenta, d.v.s. icke nedbrytbara, vilket medför att de kan orsaka skada under mycket lång tid. Data laddades ned från Lantmäteriet, Sveriges geologiska undersökning (SGU), Länsstyrelsen, Sveriges statistiska centralbyrå (SCB) samt Sveriges metereologiska och hydrologiska institut (SMHI). Dessa data inkluderade, markanvändning, jordarter, potentiella föroreningskällor, grundvattendata, utloppspunkter, enskilda vattentäkter, demografiska statistikområden och delavrinningsområden. Vidare bearbetades all data i ArcGIS Pro 3.2 för att anpassas till studiens syfte, därefter implementerades de i ArcGIS Online för att presenteras genom en interaktiv dashboard. För analys av potentiellt förorenade områden skapades buffertzoner runt de potentiella föroreningskällorna. Överlagringsanalyser utfördes därefter för att identifiera överlappande områden, som sedan riskanalyserades utifrån Crichtons risktriangel. Risktriangeln innefattar komponenterna: hot, exponering och sårbarhet, där hot är något som riskerar orsaka skada, exponering beskriver hur sårbara resurser kommer i kontakt med hotet och sårbarhet avser de resurser som påverkas mest av hotets eventuella skador. Resultatet från risktriangeln visade att: 1368,6 hektar (28,1%) av åkermarken i Torsby kommun ligger i potentiellt förorenade områden. 711,21 hektar (0,5%) våtmark, med särskilt rikt djur- och växtliv, ligger i potentiellt förorenade områden. C1030 är det DeSO-område (demografiskt statistikområde) som utgör den största risken för barn och ungdomars hälsa. C1030 är även det DeSO-område som utgör störst total risk i Torsby kommun. Området bör prioriteras för vidare utredning och eventuella åtgärder. GIS-teknik har effektivt identifierat och visualiserat potentiellt förorenade områden i Torsby kommun. Resultatet underlättar för beslutsfattare att prioritera områden för miljöövervakning och vattenkvalitetskontroll. Fortsatt arbete med omfattande analyser är dock avgörande för att skydda miljön och människors hälsa. / This thesis in land surveying technology and geographic information technology aims to identify potentially contaminated areas in Torsby Municipality using GIS (Geographic Information Systems). GIS technology enables the storage, management, analysis, and visualization of geographical data. Environmental pollution, predominantly originating from human activities, presents growing global challenges. Significant pollutants, including PFAS (Per- and Polyfluoroalkyl Substances), metals, and other organic contaminants, are of particular concern due to their non-degradable nature, posing long-term risks to both the environment and human health. Data were sourced from the Swedish Mapping, Cadastral and Land Registration Authority, the Geological Survey of Sweden, the County Administrative Boards, Statistics Sweden, and the Swedish Meteorological and Hydrological Institute. These datasets, encompassing land cover, soil types, potential pollution sources, groundwater, discharge points, private wells, demographic statistical areas, and sub-catchment areas, were processed in ArcGIS Pro 3.2 to align with the study’s objectives. Subsequently, they were implemented in ArcGIS Online to be presented through an interactive dashboard. The analysis involved creating buffer zones around potential sources of contamination. Overlay analyses were subsequently conducted to identify intersecting areas, which were then risk assessed using Crichton's risk triangle. This model considers threat, exposure, and vulnerability, with threats defined as potential sources of harm, exposure detailing how vulnerable resources interact with the threat, and vulnerability relating to the resources most affected by potential damage. Results from the risk triangle analysis indicated: 1368.6 hectares (28.1%) of agricultural land in Torsby Municipality are within potentially contaminated areas. 711.21 hectares (0.5%) of wetlands, rich in biodiversity, are affected. The DeSO-area C1030 presents the highest risk to children and youth health. C1030 also represents the highest overall risk within Torsby Municipality and should be prioritized for further investigation and possible intervention. GIS technology has effectively identified and visualized potentially contaminated zones, facilitating decision-making for environmental monitoring and water quality management. Continued comprehensive analyses are crucial for safeguarding the environment and public health.

Dans le Modèle Standard de la physique des particules, le mécanisme Cabibbo-Kobayashi-Maskawa (CKM) décrit le phénomène du mélange des quarks. De ses paramètres, l'angle gamma est celui connu avec la moins grande précision. Les mesures directes donnent une incertitude d'environ 15º, importante comparée à celle sur la valeur extraite des ajustements globaux, de 3º. Pour vérifier la cohérence du Modèle Standard, gamma doit être mesuré précisément. Cela est possible en utilisant des processus au niveau des arbres, où seules des contributions du Modèle Standard sont attendues, ou avec des processus impliquant des boucles, qui peuvent être sensibles à des effets au-delà. Des différences entre la mesure de gamma avec des diagrammes en arbres et avec des boucles pourraient être donc une indication de nouvelle physique. Cette thèse présente la première mesure des observables CP dans la désintégration B0 -> DK*0. Celle-ci est sensible à gamma du fait de l'interférence entre l'amplitude des diagrammes b -> u et b -> c, au niveau des arbres. L'asymétrie CP dans le mode B0 -> D(K+K-)K*0 et le rapport des largeurs partielles avec B0 -> D(K+pi-)K*0 sont mesurés avec 1 /fb de données récoltées par l'expérience LHCb en 2011,A_KK_d = -0,452 +/- 0,230 +/- 0,025 = A_CP+,R_KK_d = 1,360 +/- 0,366 +/- 0,075 = R_CP+. L'asymétrie CP du mode supprimé B0 -> D(K-pi+)K*0 et le rapport des largeurs partielles avec le favorisé B0 -> D(K+pi-)K*0 sont mesurés avec 3 /fb de données récoltées en 2011 et 2012,A_sup_d = -0,094 +/- 0,318 = A_ADS,R_d = 0,075 +/- 0,023 = R_ADS. Les études réalisées sur le système de déclenchement hadronique de l'expérience LHCb sont aussi présentées. / In the Standard Model of particle physics, the Cabibbo-Kobayashi-Maskawa (CKM) mechanism describes the quark mixing effect. The CKM gamma angle is one of the parameters of the Standard Model that are known less accurately. Direct measurements give an uncertainty of around 15º, large with respect to the uncertainty on the value extracted from global fits, of 3º. In order to test the Standard Model consistency, the gamma angle needs to be measured precisely. This can be done using processes at the tree-level, where only Standard Model contributions are expected, or using processes involving loop diagrams, which can be sensitive to physics beyond the Standard Model. Differences in the gamma measurement from tree and loop diagrams would be an indication of new physics. This thesis presents the first measurement of the CP observables in the B0 -> DK*0 decay. Sensitivity to gamma arises from the interference of the b -> u mediated amplitude with the b -> c one, at the tree-level. The CP asymmetry of the B0 -> D(K+K-)K*0 mode and the partial width ratio of this channel with respect to B0 -> D(K+pi-)K*0 are measured using 1 /fb of data collected by the LHCb experiment in 2011,A_KK_d = -0.452 +/- 0.230 +/- 0.025 = A_CP+,R_KK_d = 1.360 +/- 0.366 +/- 0.075 = R_CP+. The CP asymmetry of the suppressed B0 -> D(K-pi+)K*0 mode and the partial width ratio with respect to the favoured B0 -> D(K+pi-)K*0 are measured using the total 3 /fb of data collected in 2011 and 2012,A_sup_d = -0.094 +/- 0.318 = A_ADS,R_d = 0.075 +/- 0.023 = R_ADS. In addition, the studies performed on the hardware hadronic trigger of the LHCb experiment are also presented.

Le travail présenté dans cette thèse concerne l’étude des désintégrations en trois corps sans quark charmé des mésons beaux neutres, dont l’état final contient un K0S. Ce travail de recherche s’est réalisé dans le cadre de l’expérience LHCb au LHC, en analysant un échantillon d’événements de 3 fb−1 collecté dans le Run I du LHC. L’analyse d’amplitude de la désintégration B0→K0Sπ+π− représente la partie principale de ce travail de thèse. La mesure des amplitudes est effectuée au moyen d’une étude du plan de Dalitz de la désintégration intégrée dans le temps sans étiquetage de la saveur de la particule belle. Nous avons mesuré les rapports d’embranchements relatives des désintégrations quasi-deux-corps à partir de cette analyse de Dalitz. Egalement, nous avons mesuré l’asymétrie CP directe des désintégrations quasi-deux-corps B0→K*+(892)π−, B0→K0*+(1430)π−, B0→K2*+(1430)π− et B0→f0(980)K0S. Nous avons observé pour la première fois l’asymétrie CP directe dans la désintégration B0→K*+(892)π− avec une signifiance supérieure à cinq déviations standard. Cette mesure est en accord avec la moyenne mondiale, avec une précision améliorée. / Studies of charmless three-body decays of the neutral B mesons with a K0S in the final state are presented in this thesis. The analyses are performed with the full statistics recorded by the LHCb spectrometer during the Run I of the LHC. The amplitude analysis of the decay B0→K0Sπ+π− represents the main part of this thesis analysis. A time-integrated untagged Dalitz-Plot analysis of the decay is performed. The fit fractions of the quasi-two-body decays are obtained. Likewise, the direct CP asymmetries of the quasi-two-body decays B0→K*+(892)π−, B0→K0*+(1430)π−, B0→K2*+(1430)π− and B0→f0(980)K0S are obtained. The largest sensitivity is obtained for ACP (B0→K*+(892)π−). This measurement is the first observation of the CP asymmetry with a significance larger then five standard deviations. The measurement is in agreement with the world average, with an improved precision.

Au Québec, plusieurs jeunes-adultes et adultes décident à un moment donné de leur vie de s’inscrire à la formation générale des adultes (FGA) afin d’obtenir leur diplôme d’études secondaires (DES) ou de poursuivre leur parcours scolaire. L’objectif général de cette recherche est de comprendre la pratique d’enseignement la plus employée dans ce secteur -l’enseignement individualisé- et de permettre aux personnes qui la vivent au quotidien de pouvoir s’exprimer sur ses dimensions. Cette pédagogie particulière n’a pas fait l’objet d’une attention de la part de la recherche en formation générale des adultes. Dans le cadre de cette étude qualitative ethnographique, vingt informateurs ont été interviewés (dix apprenants et dix enseignants) et deux questionnaires, composés de quatre blocs chacun, leur ont été destinés. Pour atteindre le premier objectif spécifique de cette recherche, à savoir identifier les acteurs (enseignant-apprenant) du triangle pédagogique et décrire comment ils vivent leur relation dans l’enseignement individualisé, à la FGA, les composantes du triangle pédagogique de Houssaye ont été, dans un premier temps, utilisées et cela dans le but de connaitre les caractéristiques intrinsèques des formateurs et des apprenants ainsi que toutes les relations existantes entre eux. Ensuite, pour atteindre le deuxième objectif spécifique de cette recherche, à savoir mettre en lien les « perceptions » des acteurs du triangle pédagogique, en FGA, de l’enseignement individualisé au regard de l’autoformation, toutes les composantes de la théorie de l’autoformation de Carré ont été visées dans les questionnaires destinés aux informateurs. Les résultats révèlent que l’enseignement individualisé joint énormément la définition de l’autoformation éducative. / In Québec, many young adults and adults decide at some point in their lives to enroll in the adult education sector in order to obtain their high school diploma or to go further in their studies. The general objective of this research is to understand the teaching practice most used in this sector -individualized teaching and education- and to allow the people who live it on a daily basis to be able to express themselves on its dimensions. This particular pedagogy has not been the subject of attention by research in adult education. As part of this qualitative ethnographic study, twenty informants were interviewed (ten learners and ten teachers) and two questionnaires, consisting of four blocks each, were intended for them. To achieve the first specific objective of this research, namely to identify the actors (teacher-learner) of the pedagogical triangle and to describe how they live their relationship in individualized teaching, at adult education, the components of the educational triangle of Houssaye were, at first, used and this in order to know the intrinsic characteristics of the trainers and learners as well as all existing relationships between them. Then, to reach the second specific objective of this research, namely to link the "perceptions" of the actors of the pedagogical triangle, in FGA, of the individualized teaching with regard to the self-training, all the components of the theory of the self-training in Carré were included in the informant questionnaires. The results reveal that individualized teaching is a great complement to the definition of educational self-training.

Duwamish people are “the People of the Inside,” “the Salmon People”—Coast Salish people who occupied a large territory inside the Olympic Mountains and the Cascade range. Ninety Longhouses were situated where Seattle and several neighbouring cities now stand. Today, over six hundred Duwamish are urban Indigenous people without legal recognition as an American Indian tribe, still battling for rights promised by the Point Elliott Treaty of 1855. Portrayals of Duwamish history since the time of colonization are often incomplete or incorrect. A tribe member myself, I set out to record and present family stories concerning the period 1850 to the present from participants from six Duwamish families. I gathered histories told in the words of the people whose family experiences they are. It is history from a Duwamish perspective, in Duwamish voices. Collected family stories are recorded in the appendices to my dissertation. In my ethnographic study, I inquire as to what strengths have carried Duwamish people through their experiences since colonization. The stories reveal beliefs and practices which have supported the Duwamish people, and hopes for the future. Data was gathered using multiple methods, including fieldwork—visiting a master weaver; attending tribal meetings; and visiting historic sites—reading existing documents by Duwamish authors and by settlers, and interviewing, including looking at photos to elicit information. Five themes emerged from the data: Finding a True History; What Made Them Strong; Intermarriage; Working for the People; and Working with the Youth. These themes together constitute what I term the Indigenous Star of Resilience (see Figure One in Chapter Six). For me, this study has truly been swit ulis uyayus—“work that the Creator has wrapped around me” (Vi Hilbert, quoted in Yoder, 2004); work that is a gift. / Graduate / 0727 / 0452 / 0740 / juliemorgana@yahoo.ca

The study investigated South African Grade 10 Physical science learners’ reasoning about basic chemical phenomena at sub-microscopic level. The study adopted a non-experimental, exploratory and descriptive method and was principally guided by the ex-post facto research design using a concurrent embedded strategy of mixed qualitative and qualitative approach. A total of 280 grade 10 physical science learners in their intact classes and six of their teachers participated in the study. The 280 physical science learners comprised of 100 students from two top performing schools, 100 learners from two middle performing schools and the last 80 learners were drawn from two poor performing schools in Gauteng Department of Education’s Tshwane North District. A two-tier multiple-choice paper and pencil Test of Basic Chemistry Knowledge (TBCK) based on the three levels of chemical representation of matter was administered to the 280 physical science learners in their Grade 11 first term to collect both quantitative and qualitative data. In addition to the TBCK, focus group discussions (FGDs) with learners, teacher interviews and document analysis were used to triangulate data. The results revealed that most Grade 10 learners find it easy to identify pure elements and the solid state but find it difficult to negotiate between the three levels (macroscopic, sub-microscopic and symbolic) of chemical representation of matter. It became clear that learners experienced more difficulties in the concepts of basic solutions, acidic solutions, concentration and ionic compounds in solution. It also became apparent that some learners could not tell differences between a diatomic element and a compound indicating conceptual problems when they reason at particle level, and as a result they could not identify a mixture of elements. The results also indicated that the concepts of pure compounds and mixtures of compounds were not easy to comprehend as most learners took a pure compound for a mixture of atoms and a mixture of compounds for a mixture of elements. It is therefore concluded that learners find it difficult negotiating the three levels of chemical representation of matter. However, it is not clear whether the misconceptions the learners showed could be completely attributable to the concepts involved or the nature of the sub-microscopic models that were used in the test as it was also revealed that most teachers were not using sub-microscopic representations during instruction to enable learners to think at particle level. Furthermore, justifications to the multiple-choice tasks revealed lack of understanding of basic chemical concepts as well as language problems amongst learners as they could not clearly express their reasoning. Based on the results, some recommendations to educators, chemistry curriculum planners, teacher education and the chemistry education research field are suggested. / Science and Technology Education / D.

Nicknames have been analysed, recorded and processed in many diverse ways by different languages, scholars and communities. In Zulu, many works of similar type have all been the size of an article up until 1999. This research on the subject is one of the first done in this depth. Nicknames form part of a Zulu person's daily life. They identify him/her more than the real or legal name. They shape him/her more than any other mode of address. They influence behaviour, personality, interaction based activities and the general welfare of an individual. They discipline, they praise, they mock too. Surprisingly, they are regarded as play items. They are even termed playnames (izidlaliso). But they are as serious as any item that makes an individual to be a significant figure in the community. They are unique in the sense that they stick more obstinately on the victim should he/she try to get rid of them. They are capable of staying for life. They only vanish to give others a chance to feature on the same individual. They are so poetic. A talented onomastician can tell a full story about an individual without him grabbing what is being said about him just because the story is spiced with just a single figurative nickname. They haunt the whole arena of the parts of speech in a language, especially the Zulu language. They modify the well known meaning of words into special references that paint in bright colours the character of an individual. Zulu nicknames processes visit all possible languages and adapt items from into Zuluised special terms that a capable of inheriting an onomastic status. They originate even from the most sensitive sources like people's private lives. The only challenging area about nicknames is that bearers do not want to expose them to peale who are not known to them, even if they do not fall into a category of nicknames for ridicule. Finally, nicknames have been exposed here as linguistic items that organise the community into makers and bearers, and then users of nicknames. / African Languages / D.Litt. et Phil.

Nematode communities in black pepper (Piper nigrum L.) agricultural soil in Thanh An, Binh Phuoc province, were investigated. Soil samples were collected in February 2012 at 9 selected sites belonging to 3 pepper groves. The structure of nematode communities and critical ecological indices were determined to estimate environmental status. 26 genera were found. Of those, plant parasitic nematodes such as Meloidogyne, Helicotylenchus, Hoplolaimus, Psilenchus, and Tylenchidae always appear with high frequency and density, whereas the carnivorous nematodes were rarely detected. The nematode density correlates to the concentration of the total organic matter which correlates closely to the (Ba + Fu) proportion showed by the regression equation y = 0.0223x + 1.6819 with R2 = 1. The ecological triangle model, but not the maturity index (MI), apparently showed the status and processes (decomposition and mineralization) which may be happening in the soils of areas studied. The first grove is rich in nutrient but stressed by chemicals. The second grove is stable, with no chemical stress, but has low nutrient contents. The third grove is affected by chemicals but to a lesser extent than the first one. / Các quần xã tuyến trùng trong hệ sinh thái đất trồng tiêu ở khu vực xã Thanh An, tỉnh Bình Phước được nghiên cứu. Các mẫu đất được thu nhận trong tháng hai năm 2012 tại 9 điểm thuộc 3 vườn tiêu. Cấu trúc quần xã tuyến trùng và các chỉ số sinh thái đã được xác định để qua đó đánh giá trạng thái môi trường. Tổng cộng có 26 giống tuyến trùng được tìm thấy. Trong đó, các loài tuyến trùng ký sinh thực vật như Meloidogyne, Helicotylenchus, Hoplolaimus, Psilenchus, và tuyến trùng ăn nấm Tylenchidae luôn xuất hiện với tần suất và mật độ cao, trong khi tuyến trùng ăn thịt lại hiếm khi được phát hiện. Mật độ tuyến trùng tương quan với lượng chất hữu cơ tổng số mà nó tương quan chặt chẽ với với tỉ lệ nhóm (Ba + Fu) được thể hiện ở phương trình hồi quy là y = 0.0223x + 1.6819 với R2 = 1. Mô hình tam giác sinh thái, nhưng không phải chỉ số tăng trưởng MI, thể hiện rõ trạng thái và các quá trình (sự phân hủy và sự khoáng hóa) có lẽ đang diễn ra trong đất của khu vực được nghiên cứu. Vườn thứ nhất thì giàu dinh dưỡng nhưng bị áp lực bởi hóa chất. Vườn thứ hai khá ổn định, không chịu áp lực hóa chất, nhưng hàm lượng dinh dưỡng rất kém. Vườn thứ ba bị tác động bởi hóa chất nhưng ở mức độ thấp hơn vườn thứ nhất.

在2006年1月，立法院通過了總金額合計高達1410億水患治理特別條例、石門及其集水區整治特別條例。本文以許多民間非營利組織為監督治水預算成立的1410大禹治水聯盟為研究個案，希望能瞭解立法過程裡，民間聯盟如何監督公共政策？又如何打破國會與官僚的結盟結構，實際影響政策？本文採用深度訪談、報章資料與參與觀察等方式，藉由McAdam的政治機會結構理論為分析架構，以說明治水預算裡行動者擴編預算的動機與過程。並分析在立法院審查各階段治水聯盟的因應策略、實際行動和內部運作，以及監督成效。研究發現在地方水患陰影下，又面對官僚、國會與地方政府三者鐵三角般的互利合作，主張審慎監督的治水聯盟其實無力回天。一方面因議題範圍實在太大，無法動員特定地區相關者；另一方面也是鐵三角間同盟關係非常穩固，國會遊說發揮不了作用。故只能藉少數友好立委，在朝野協商爭取加入更多資訊公開、績效評估與公民參與機制。透過這些機制，在後續八年政策執行過程中找出更多公共參與和監督的著力點。藉此也讓原先僅有地區性互動的環保運動與社區大學運動在本案上交會。此新合作方向是否會對未來環保運動帶來新的在地網絡與群眾支持，值得後續觀察與研究。 / In January 2006, the Legislative Yuan passed the Special Enactment on Flood Management in Areas Susceptible to Floods and the Special Enactment on Restoration of Shi-Men and its Catchments Area amounting to NT$141 billion. This paper makes a study of the 1410 Ta-Yu Water Management Alliance formed by a number of civil non-profit organizations for the purpose of supervising and auditing the water management budget. The study seeks to understand how the civil alliance supervises public policies during the legislative process and how they break the alliance structure between the Legislative Yuan and bureaucracy to actually influence policies. By using McAdam’s political opportunity structure theory as its analysis structure, this paper gives an account of the motives and processes of activists in the creation of the water management budget through in-depth interviews, newspaper reports and participate observation. It also analyzes the countering strategies, activities, internal functioning and the results of the supervisory actions of the Water Management Alliance. This research discovered that in the face of the alliance’s proposition of prudent supervision could not be upheld in the face of mutual cooperation within the iron triangle of bureaucracy, the Legislative Yuan and local government. On one hand is the alliance’s inability to mobilize related parties in specific areas due to the issues covering too wide a range and on the other hand is the solid relationship within the iron triangle alliance and negates lobbying efforts in the Legislative Yuan. It is only by a few friendly legislators that mechanisms for the increased disclosure of information, performance evaluation and civil participation were added during negotiations between the ruling and opposition parties. Through these mechanisms it is hoped that more foothold for public involvement and supervision can be found in the following eight years of policy implementation. Also, such mechanisms would allow conservation movements and community college movements which used to be limited to territorial interactions to meet. Whether this new direction in cooperation brings new grassroot support for future environmental movements remains worthy of follow up observation and research.
