In 1990, creosote contamination was discovered at the location of a railroad tie treatment facility active in the 1950s until 1973. In 1997, a phytoremediation field study was implemented with the planting of 1,026 hybrid poplar trees and 36 cells of vegetated and unvegetated grass and legume treatments. The hybrid poplar tree phytoremediation system was designed to control infiltration and groundwater flow and enhance subsurface remediation. The grass phytoremediation system was designed to control erosion and enhance surface soil remediation. The overall objectives of this study were to: (1) assess the extent of subsurface remediation, (2) determine the mechanisms of remediation attributable to the hybrid poplar tree phytoremediation system and microbial degradation, (3) assess the effects of the grass phytoremediation system on surface soil remediation, and (4) determine the mechanisms of surface soil remediation resulting from the grass phytoremediation system. / Master of Science

Cette thèse examine l’imagination des systèmes de mesure de la performance au sein de l’industrie pharmaceutique. Par une observation participante étendue dans une grande entreprise pharmaceutique et des entretiens dans cette industrie, les trois articles de cette thèse explorent les influences intra et extra-organisationnelles qui agissent sur la forme et les raisons des systèmes de rémunération que les sociétés pharmaceutiques utilisent pour leur force de vente. Le premier article considère que les systèmes comptables émergent d’un ensemble d’inscriptions dramatisées qui mettent en scène, encadrent et médiatisent l’interaction entre les différents acteurs, internes et externes à l’organisation, qui participent à la fabrication d’un algorithme de rémunération. Le deuxième article théorise de quelle manière moral imaginaries sont constitués en objets comptables et comment les instruments comptables agissent comme médiateur moral. Il présente les systèmes émergents de mesure de la performance en tant que dispositifs de calcul moral façonnés par les imaginaires moraux contrastés de concepteurs hétérogènes. Le troisième article se concentre sur la manière dont les systèmes de mesure de la performance émergent et se stabilisent dans le contexte des marchés, afin d'explorer les infrastructures comptables au niveau de l’industrie que permettent aux acteurs organisationnels de visualiser, rendre compte et agir sur le marché lorsque ce dernier est invisible à pour ses participants. Pour que les systèmes de mesure de la performance fonctionnent sur un marché, il est nécessaire d’avoir une collaboration au sein du secteur, des opacités construites et des processus de (de)commercialisation de l’identité des acteurs. / This thesis examines the field-level imagining of Performance Measurement Systems in the pharmaceutical sector. By means of an extended participant observation in a Big Pharma company and interviews in the pharmaceutical sector, the three articles of this thesis explore the intra- and extra-organizational influences that act upon the shape and rationales of the compensation systems pharmaceutical companies operate for their sales-force. The first article explores accounting systems as emerging from a set of dramatized inscriptions that stage, frame, and mediate interaction among the different actors, internal and external to the organization, that participate in the fabrication of a compensation algorithm. The second article theorizes in what way moral imaginaries are constituted into accounting objects, and how accounting acts as a moral mediator. It shows emergent performance measurement systems as moral calculating devices that are shaped by, and engage with, the contrasting moral imaginaries of heterogeneous designers. The third paper brings the concern with how performance measurement systems emerge and stabilize in the context of markets, to explore the field-level accounting infrastructures that enable organizational actors to visualize, account for, and act upon the market when the market is invisible to its participants. For performance measurement systems to work in a market, it is suggested, they require field-level collaboration, constructed opacities, and processes of marketization and de-marketization of actors’ identities.

Agriculture is facing many challenges, such as decreased biodiversity, soil erosion, water scarcity, and social inequality, because of industrial farming and its focus on high yields at the expense of sustainability. This also includes Thailand and the province of Ratchaburi. There are, however, some farmers that have pursued sustainable agriculture in the region. The purpose of the study is therefore to investigate how these sustainable farming practices can contribute to increased prosperity, self-sufficiency, and an improved environment in Ratchaburi. Specifically, the study examines the strengths and weaknesses of sustainable agriculture in the region, as well as the opportunities and threats they face. Qualitative interviews were completed with farmers from three sustainable farms in the region. The results were analyzed with the help of PESTLE to describe the macro-factors that influence the agricultural environment .Thereafter a SWOT analysis was performed to highlight the strengths and weaknesses of each farm as well as relate these to the opportunities and threats identified in the PESTLE analysis. The study found that the key strengths were multi-crop cultivation, product development, self-sufficiency and broad knowledge combined with collaboration. Several weaknesses arose from small-scale operations, which also made it challenging to make use of the opportunity of niche markets. A major challenge is the relatively low demand for sustainable products. Future studies could further examine how organic certifications can impact the demand for sustainable products, as well as how small sustainable farms can effectively reach niche markets. / Jordbruk står inför många utmaningar, så som minskad biologisk mångfald, erodering, vattenbrist och social ojämlikhet, till följd av det industriella jordbruket och dess fokus på stora skördar på bekostnad av hållbarhet. Detta innefattar även Thailand och provinsen Ratchaburi. Däremot finns det en del bönder som trotsat de konventionella metoderna och bedriver hållbara jordbruk, främst genom diversifierade grödor och skapandet av naturliga ekosystem. Syftet med studien är därför att undersöka hur dessa hållbara jordbruk kan bidra till ökat välstånd, självförsörjning och förbättrad miljö i Ratchaburi. Mer specifikt undersöker studien vilka styrkor och svagheter hållbara jordbruk i regionen har, samt vilka möjligheter och hot de ställs inför. Metoden som användes var kvalitativa intervjuer med bönder från tre hållbara jordbruk i regionen för att sedan skapa en gemensam PESTEL-analys för gårdarna samt en SWOT analys för respektive gård. PESTEL-analysen beskriver och analyserar vilka makro-faktorer som påverkar deras omgivning, medan SWOT analysen lyfter fram styrkorna och svagheterna för gårdarna och analyserar deras möjligheter och hot, dels utifrån deras svar, dels utifrån PESTEL-analysen. Studien fann att de viktigaste styrkorna var bred kunskap, självförsörjning, samverkan, produktframtagning och en mångfald av grödor och produkter. De övergripande svagheterna var dålig tillgång till marknader samt småskalighet. Möjligheterna var att nå nya marknader, i samband med en ökad medvetenhet och efterfrågan på hållbara produkter, samt utnyttjande av subventioner och ökad användning av e-handel. De främsta hoten var konkurrens med andra jordbruk och stora industrier, kapital- och teknologiska begränsningar. Framtida studier kan vidare undersöka hur ekologiska certifieringar kan påverka efterfrågan på hållbara produkter, samt hur hållbara jordbruk kan nå till nischade marknader för deras produkter på bästa sätt.

This study was funded by a scholarship from the Swedish International Development Cooperation Agency (SIDA) as a Minor Field Study. The social economic development in Tanzania is a major challenge due to a continuing high rate of population growth. A growing   population   puts   increased   strain   on   healthcare,   food   supply   and   the environment.  Early childbearing limits women’s ability to educate themselves and contribute to society. The definition of family planning (FP) is to keep a sustainable population growth through reducing the family size. The government of Tanzania has developed  a  plan  for  FP,  which  includes  a  goal  that  60  percent  of  women  in reproductive age will use contraceptives in 2015. Healthcare professionals have a great potential to encourage lifestyles changes. It is therefore important to investigate the nurses’ experiences of teaching FP to increase the knowledge about their experiences. The aim of the study is to investigate nurses’ experiences of education about FP in the Rufiji district in Tanzania. This is a qualitative study and the data was collected through interviews using a semi structured open-ended question guide. The nurses’ experiences of teaching patients in FP concerns four different areas. Firstly, they have a variety of strategies to execute the education. Secondly, they describe what is necessary to create a meeting with the patient. Thirdly, the patients have needs that have to be met in a learning situation. Finally, even though it’s subtle, they empower the patient, which lays the foundation for making lifestyle changes. The key finding that the nurses spoke of as the  most  important  factor  when  teaching  is  the  importance  of  creating  a  good relationship with the patient.

Jordan is a developing country which is taking measures to make the situation in the society more equal between males and females. Former research has showed that it, worldwide, sometimes is great differences between the genders in the health care. This thesis illuminates how it is to work in an intensive care unit and if there are differences between male and female intensive care nurses influencing on the provided care. Twenty intensive care nurses from four intensive care units at Jordan University Hospital were included in the study. Both field notes and an observation schedule were used to gather data. The field notes captured the overall experience of working in the intensive care area and were analyzed by thematic content analyze. The observation schedule concentrated on how long time was spent and which activities were performed bedside. Data from the schedule was compared between the units and between male and female intensive care nurses caring for male and female intensive care patients. The field notes showed that even if the units were busy and crowed the silence and calmness were present. Cooperation was essential and trust and knowledge were spread. Often a warm and comfortable feeling surrounded the personnel and they seemed to like it at work. The observation schedule showed that in the medical and surgical intensive care units the intensive care nurses spent more time and performed a greater number of bedside activities compared to the pediatric and main intensive care units. Female intensive care nurses who cared for male intensive care patients performed less bedside activities and when they cared for a female intensive care patient they spent less time bedside compared to the other groups. In all the units and all the groups the most frequent performed activity was to have a look at the equipment, followed by have a look at the patient. The results can however be questioned since it is a small study accomplished by a single researcher, in some few intensive care units at one hospital. / Program: Specialistsjuksköterskeutbildning med inriktning mot intensivvård

Malaria is a big problem and a major cause of death and illness among children and adults in tropical countries (World Health Organization, 2010). It is the biggest threat for children in Kenya and leads to death in approximately 36,000 children (<5 yrs) every year. When infected with malaria; the patient ends up with some kind of self-care deficit and need access to health care.Research about how nurses can support self-care in patients with malaria is lacking. If no plan for how to take care of a patient with malaria exits, treatment can differ, which in turn can result in poorer outcome for the patient. The aim of the study was to investigate how the nurses at Moi District Hospital in Voi support self-care in patients diagnosed with malaria. The study was carried out with five qualitative semi-structured interviews. Data was analyzed with a deductive content analysis. The result showed that nurses teached and encouraged patients to perform self-care; they identified patient status, they acted for the patient, guided him or her and tried to provide a developmental environment. Teaching was the most common way to support self-care, probably because of lack of recourses. / Program: Sjuksköterskeutbildning

In recent years ICT has gotten sustained interest in which it’s seen as a tool for development andsocial transformation. There have been a rise of ICT4D (ICT for development) initiatives in theinternational arena. The Philippine organization Foundation for Media Alternatives (FMA) isworking with the intersection of ICT and women’s empowerment to advocate women’s rights andissues in the online space as well as increasing women’s strategic use of ICT. This paper is aMinor Field Study conducted in Quezon City, the Philippines, which explores FMA’s Gender andICT program. The aim of the study is to examine the strategies and practices for womenempowerment through ICT as well as mapping the major challenges in their work. The study wasconducted through observations and interviews with the members of FMA as well as women froman assisted urban poor community. The result outlines the main practices taken in the program toreach an understanding of the work done for women’s empowerment. Furthermore, the studyportrays that the full potential of the practices can’t be fulfilled due to the current environmentFMA are operating in. The experienced challenges in their work have been characterized into fivecommon areas; funding, the political environment, the cooperation, the unsafe online space andlastly the socioeconomical divide in the society.

A alelopatia, na qual uma espécie causa efeitos negativos sobre outra através da liberação de substâncias químicas, é um fenômeno que pode afetar comunidades vegetais. Em alguns casos, o estabelecimento de arbustos aromáticos em formações densas, com apenas poucas espécies ocorrendo em suas proximidades, é um padrão que tem sido relacionado aos efeitos fitotóxicos dos voláteis que os mesmos liberam. Em campos dos sul do Brasil, esse padrão de estabelecimento frequentemente ocorre para as espécies arbustivas aromáticas Heterothalamus psiadioides Less e Baccharis patens Baker, indicando a possibilidade de alelopatia. Dessa forma, o presente estudo teve como objetivo determinar se H. psiadioides e B. patens são fitotóxicas e se isso implica em efeitos negativos sobre a comunidade vegetal na qual os arbustos ocorrem. Em ensaios em laboratório, os efeitos dos voláteis liberados diretamente das folhas frescas e secas de H. psiadioides e B. patens foram testados sobre a germinação e o crescimento das plantas-alvo alface e cebola nas quatro estações do ano. Em um estudo em campo, foram avaliadas cobertura e biomassa vegetal, número de mudas, diversidade, riqueza, e variáveis de estrutura da vegetação no entorno de ambas as espécies arbustivas e onde não havia arbustos. Nos bioensaios, os voláteis de H. psiadioides e B. patens causaram inibição na porcentagem e velocidade de germinação e redução no tamanho da raiz e da parte aérea das plantas-alvo, sendo que folhas frescas apresentaram maior fitotoxidez. Esses parâmetros foram mais afetados por H. psiadioides que por B. patens em todas as estações, e os efeitos de ambas foram menores no verão. Em relação à investigação em campo, que objetivou avaliar os efeitos da espécie muito fitotóxica H. psiadioides sobre a comunidade vegetal, não foram observadas evidências de alelopatia. Houve maior riqueza e diversidade próximo a H. psiadioides, devido à menor cobertura de gramíneas dominantes. Variáveis de estrutura da vegetação e intensidade de luz explicaram os padrões observados de forma mais conclusiva que alelopatia. Esse estudo sugere que o potencial alelopático de plantas pode ser superestimado em bioensaios e que estudos em campo são necessários para demonstrar se efeitos alelopáticos são realmente relevantes em comunidades vegetais. Ainda, o trabalho ressalta a importância de conduzir estudos mais realistas em laboratório e de utilizar controles em estudos em campo. / Allelopathy, in which a species causes negative effects on another through the release of chemical substances, is a phenomenon that may affect plant communities. In some cases, the establishment of aromatic shrubs in dense stands, with few other species occurring in their surroundings, has been related to the phytotoxic effects of volatiles released by these shrubs. In South Brazilian grasslands, this pattern of establishment often occurs for the aromatic shrub species Heterothalamus psiadioides Less and Baccharis patens Baker, indicating the possibility of allelopathy. Thus, this study aimed to determine if H. psiadioides and B. patens are phytotoxic and if this implicates in negative effects on the plant community in which the shrubs occur. In laboratory assays, the effects of the volatiles released directly from fresh and dry leaves of H. psiadioides and B. patens on germination and growth of the target plants lettuce and onion were evaluated in four seasons. A field study was carried out, in which vegetation cover and biomass, number of seedlings, diversity, richness, and variables of vegetation structure were evaluated in the surroundings of both species and where there were not shrubs. In the bioassays, H. psiadioides and B. patens volatiles inhibited the germination rate and speed of germination and reduced the root and shoot length of the target plants, with fresh leaves showing higher phytotoxicity. These parameters were more strongly affected by H. psiadioides than by B. patens in all seasons, and effects of the both shrubs were lower in summer. In relation to the field investigation that aimed to quantify the effects of the highly phytotoxic H. psiadioides on the plant community, no evidences of allelopathy were found. Richness and diversity were higher near H. psiadioides, due to lower cover of dominant grasses. Variables of vegetation structure and light intensity explained vegetation patterns more conclusively than allelopathy. This study emphasizes that the allelopathic potential of plants can be overestimated in bioassays, and that field studies are necessary to elucidate if allelopathic effects are in fact significant in plant communities. Still, the relevance of conducting more realistic laboratory studies and of using controls in field studies is highlighted.

In contemporary software development, an emergent understanding of the problem domain and envisioned goals forms the basis of designing, testing and development activities. Lack of a common understanding of the domain can result in costly rework or client dissatisfaction. Research shows that the development of shared understanding in this context is a complex and error-prone process and there is room for improvement. Is this because practitioners are not following suggested practice from literature? Or are the actual barriers to shared understanding not being addressed by current tools and techniques? Is the development of shared domain understanding even viewed as problematic (or even important) by practitioners? These are some questions that need to be investigated in order to effectively design process improvements and tool support in this area, yet there is little information related to this. This study takes a multi-case study approach, which incorporate semi-structured interviews with representative from ten small-to-medium organisations. This study focuses on the vendor’s perspective and includes a mix of application domains. Result of the interviews is analysed to discover themes and patterns related to an analysis framework constructed from the literature review. The findings indicate that vendors perceive the process of developing shared application-domain understanding with their clients as being both problematic and important to a successful implementation. Twelve barriers have been identified from the analysis. The results also confirm that the process of sharing understanding development is generally perceived as being evolutionary and collaborative. This process is described by most interviewees comprises iterative phases of elicitation, confirmation and refinement of the understanding. A definite preference for face-to-face interaction is evident at regular times throughout development, particularly in early stages, although the importance of ad-hoc communications by phone or email, as domain knowledge needs arise, is also emphasised. Access to cooperative domain-expert throughout development is generally seen as a critical success factor. Several companies report using in-house domain-expert as client “proxies” in this regard. There is a mix of attitudes apparent regarding the direct communications of developers with client stakeholders. This ranged from insisting that developers are involved from initial elicitation and “kick-off” meetings, to “shielding” developers almost entirely from client. In terms of representations of understanding, participants relate natural-language, screen-shots, mock-ups, prototypes and product-demonstrations as the most useful artefacts for sharing and confirming understanding of the problem domain. They emphasise the importance of flexibility and client familiarity with the representations. In general, there is no clear separation between problem and solution spaces evident when the interviewees discussed representations of understanding, and the preference seems to be for concrete rather than abstract representations. In conclusion, comparisons between the findings and literature generally confirm contemporary thinking regarding domain knowledge sharing, although a number of barriers were given particular emphasis in this field study. The use of computer-based tool support is not widespread and the need to improve the domain knowledge sharing process and tool support in practice is widely acknowledged by the participants in this investigation. This study has identified some fruitful areas of research in this regard.
