Antimoine (Sb) et tellure (Te), sont des contaminants peu étudiés (isotopes stables) et leurs radionucléides artificiels peuvent être rejetés dans le milieu aquatique lors des accidents nucléaires. La connaissance de leurs comportements biogéochimiques respectifs est nécessaire à l'évaluation du risque radiologique post-accidentel.Ce travail présente des données originales sur le comportement biogéochimique de Sb et de Te dans les systèmes de transition continent-océan, tels que l'estuaire de la Gironde et la rivière du Rhône. Un suivi de 14 ans et des campagnes océanographiques dans le bassin versant de l’estuaire de la Gironde ont permis d’identifier des concentrations, des flux, et des réactivités (variabilités spatio-temporelles et distribution solide/liquide) plus élevés pour Sb que pour Te, mettant en évidence un comportement additif pour Sb et de soustraction pour Te le long des gradients de salinité et de turbidité estuariennes. Des expériences couplant l’adsorption d’isotopes marqués sur des matières en suspension (MES) et des extractions sélectives des phases porteuses, suggèrent que les formes apportées de Sb et de Te sont plus mobiles et potentiellement plus biodisponibles que leurs équivalents naturels. De plus, l’observation de la bioaccumulation non-négligeable de Sb et de Te naturels dans les huîtres sauvages à l’embouchure de l’estuaire permet d’envisager une absorption potentielle de leurs homologues radioactifs.Ainsi, le développement de scenarios de dispersion de radionucléides rejetés dans les zones de transition dépendra (i) de la position géographique de la source (Rhône) et/ou de la zone de turbidité maximale (ZTM; système fluvio-estuarien de Gironde), (ii) de la situation hydrologique pendant et post accident, ainsi que (iii) de la réactivité biogéochimique et des temps de demi-vies des radionucléides. Les premiers scénarios de dispersion de radionucléides dans l'estuaire de la Gironde suggèrent (i) un transport préférentiel de Sb dissous vers la zone côtière, et (ii) une forte rétention de Te radioactif dans la ZTM si la dernière est présente en aval du site d’accident, impliquant le risque de migration saisonnière de la radioactivité vers la ville de Bordeaux pendant l’étiage suivant. Ainsi, la dynamique intra estuarienne (marée, débit et migration de la ZTM) sera le facteur prédominant dans le devenir de Te radioactif, depuis son rejet jusqu’à sa désintégration complète en iode radioactif. L’ensemble de ce travail met en évidence la nécessité d’une évaluation plus approfondie de la radiotoxicité potentielle de Sb et Te lors de leurs rejets en milieu aquatique. / Antimony (Sb) and tellurium (Te) are relatively uncommon contaminants (stable isotopes) and may form short-lived fission products (radionuclides) released into the environment during nuclear power plants accidents. Little is known about their respective biogeochemical behaviours, necessary for general contamination studies and post-accidental radiological risk assessment.This work provides original knowledge on Sb and Te biogeochemical behaviour in highly dynamic continent-ocean transition systems: the Gironde Estuary and the Rhône River. Concentrations, spatial/temporal variations, solid/liquid partitioning (Kd), and fluxes are studied from long-term records at the watershed scale. Four estuarine sampling campaigns during contrasting hydrological conditions show higher Sb solubility and Te particle affinity in the estuary than in the upstream fluvial reaches. Historical records (1984-2017) in wild oysters from the estuary mouth do not show clear trends of past or recent contamination, but measurable bioaccumulation suggests that potential uptake of radionuclides is likely to occur. Combined adsorption experiments using isotopically-labelled (spiked) Sb and Te, and subsequent selective extractions of carrier phases from suspended particulate matter (SPM) suggest that spiked Sb and Te are more mobile and potentially bioaccessible than their environmental (inherited) equivalents. Radiotracer adsorption experiments using environmentally representative concentrations of both Gironde and Rhône systems underpin that highly soluble elements may show contrasting reactivity between inherited and spiked forms.Radionuclide dispersion will greatly depend on (i) the geographical position of the source (Rhône) and/or the maximum turbidity zone (MTZ; Gironde fluvial-estuarine system), (ii) the succession of hydrological situations during and after the accident, and (iii) the biogeochemical reactivity and half-lives of the radionuclides. First scenarios on hypothetical dissolved radionuclide dispersion in the Gironde Estuary suggest (i) low sorption of Sb to the SPM, implying a transport of radionuclides in dissolved phase towards the coast, and (ii) high retention of Te within the MTZ, especially for accidental releases during flood conditions, linking the fate of radioactive Te to long estuarine SPM residence times (1-2 years). Potential upstream migration of Te radionuclides in the MTZ towards the city of Bordeaux during the following summer season and Te decay into radioactive iodine warrants further evaluation of the associated potential radiotoxicity.

Per- and polyfluoroalkyl substances (PFASs) are a group of emerging chemicals which havereceived increasing attention due to their toxicity, persistent properties, and global distribution.In this study, sorption coefficients (Kd and KOC) of PFASs in an industrial site in Sweden wereevaluated. Sorption is a measures of the mobility of a substance in the subsurface, and is a keyfactor in environmental risk assessments. Sorption coefficients were calculated both from fieldsamples processed in laboratory batch tests, and from a simplified approach involving the totalconcentrations in soil and groundwater (field-derived). Soil was sampled from two locations ofthe site; C8 and M6. Field-derived values were calculated based on concentrations which werehistorically measured. The aim was to compare the two methods, and to compare the valueswith literature values as well as guideline sorption values established by the SwedishGeotechnical Institute (SGI). Sorption coefficients for PFHxA, PFHpA, PFOA, PFHxS, PFOS, 6:2 FTS and PFBS could beestablished. Results showed that laboratory-derived sorption coefficients were significantlyhigher than field-derived sorption coefficients. Laboratory-derived sorption values were alsohigher than to SGI’s preliminary sorption values. Comparing C8 and M6 KOC values toliterature values, PFHpA, PFHxA, and PFBS exhibit values above literature values. PFOA,PFHxS, PFOS exhibit KOC values within the range of literature values. According to thesorption coefficients, predictive scenarios of leaching through the unsaturated zone weremodelled, and it was concluded that leaching was higher in M6 compared to C8. The resultsalso showed that an increase in precipitation increased the leaching. / Per- och polyfluorerade alkylsubstanser (PFAS) är en grupp nyligen uppkomna kemikalier somhar fått ökad uppmärksamhet pga. deras toxicitet, ihärdiga egenskaper och globala utbredning.Detta examensarbete har studerat fördelningskoefficienter (Kd och KOC) för PFAS inom ettindustriområde i Sverige. Fördelningskoefficienter är ett mått på mobilitet av en substans iunderjorden, och det är en viktig komponent i riskbedömningar inom förorenad mark.Fördelningskoefficienter beräknades dels utifrån jordprover som tagits i fält och analyserats ilaboratorium med extraktionsmetoder, och dels utifrån ett förenklat tillvägagångssätt därberäkning skett med hjälp av tidigare uppmätta koncentrationer i jord och grundvatten.Jordprover från två områden inom industriområdet; C8 och M6, togs och analyserades.Fältbaserade fördelningskoefficienter beräknades utifrån koncentrationer som tidigare mättsvid brunnsinstallation och vid grundvattenövervakning. Målet med studien var att jämföra detvå metoderna, och dessutom jämföra fördelningskoefficienterna med motsvarande i värdenlitteraturen samt riktvärden för fördelningskoefficienter som Statens Geotekniska Institutet(SGI) arbetet fram. Fördelningskoefficienter för PFHxA, PFHpA, PFOA, PFHxS, PFOS, 6:2 FTS and PFBS kundeberäknas. Resultatet visade att laboratorie-baserade fördelningskoefficienter var betydligthögre än fältbaserade fördelningskoefficienter. Laboratorie-baserade fördelningskoefficientervar även högre än de preliminära riktvärden för fördelningskoefficienter som SGI etablerat. Vidjämförelse av fördelningskoefficienter för C8 och M6 kunde det konstateras att PFHpA,PFHxA, and PFBS hade högre värden än motsvarande i litteraturen. PFOA, PFHxS, PFOSvisade på värden som var inom intervallet av värdena från litteraturen. Med hjälp av deberäknade fördelningskoefficienterna modellerades prediktiva utlaknings-scenarier. Utifrånresultatet sker utlakningen i större grad i M6 jämfört med C8. Utlakningen ökade även vidförhöjd nederbörd.

Begreppet influencer blir mer och mer välkänt för varje dag. Begreppet syftar till ett yrke som vuxit fram i takt med internet. Även om det finns mycket information att tillgå kring fenomenet finns det många aspekter som fortfarande icke blivit belysta. Den information som finns att tillgå kring ämnet är inte heller i vetenskaplig tappning. Syftet med studien är att analysera och redogöra för hur influencer marketing kan påverka tillväxten för ett företag. Härtill studeras influencers inverkan på varumärkesbyggandet i relation till tillväxt. Följande kommer en fallstudie i samarbete med klädföretaget NA-KD presenteras. NA-KDs snabba tillväxt kommer förklaras med lämpligt teoretiska underlag och inte minst av medgrundaren själv. Det moderna sättet att marknadsföra via sociala medier med influencers kommer vidare att undersökas i ljuset av olika aspekter. Hur ett samarbete med en eller flera influencers ser ut kommer att undersökas med koppling till hur strategin har hjälpt NA-KD att växa under kort tid. Varumärkesutveckling och teorier kring ett företags tillväxt är två andra viktiga områden som kommer att studeras för att uppsatsen ska få en relevant och genomtänkt slutsats. Alla presenterade teorier kommer att kopplas till NA-KDs egna tillväxt. Metoden vald för följande uppsats är av den kvalitativa typen. Empiriinsamlingen kommer att bestå av en intervju med en medgrundare i fallföretaget, NA-KD. Vidare kommer företagets hemsida och Instagramkonton observeras, likaså kommer fyra utvalda influencers konton observeras. Även sekundär data så som NA-KDs årsredovisning samt en överskådlig presentation av ett par konkurrenter läggs fram. Efter analys av empirin trädde tydliga slutsatser fram. Kopplingar mellan influencer marketing och tillväxt blev ett klart faktum. Likaså blev samarbetet mellan företaget och person förtydligat. Det stod även klart att NA-KD ligger rätt i tiden och grundades när influencers redan vuxit fram och fått en stor inverkan. / The term influencer is becoming more and more known for each day. The term aims at a profession that has emerged in line with the internet. Although there is much information available about the phenomenon, there are many aspects that have not yet been illuminated. The information available on the subject is also not of scientific sort. The purpose of the study is to analyze and explain how influencer marketing can affect the growth of a company. In addition, influencers affect the brand building. Following thesis will consist of a case study in collaboration with the clothing company NA- KD. The rapid growth of NA-KD will be explained by appropriate theoretical evidence, and not least by the co-founder himself. The modern way of marketing through social media with influencers will be investigated in light of various aspects. How cooperation with one or more influencers looks will be investigated in conjunction with how the strategy has helped NA-KD grow in a short period of time. Brand development and theories about a company's growth are two other important areas that will be studied in order for the thesis to have a relevant and well-reasoned conclusion. All theories presented will be linked to NA-KD’s own growth. The method chosen for the following thesis is of the qualitative type. The empirical collection will consist of an interview with a co-founder of the chosen company, NA-KD. Furthermore, the company's website and Instagram accounts will be observed, as well as four selected influencer's accounts that will also be observed. As well as secondary data such as the NA-KD annual report and a review of a few competitors will be presented. After analysis of the empiric data, clear conclusions emerged. Linkages between influencer marketing and growth became a clear fact. Likewise, cooperation between the companies and individuals was clarified. It was also clear that NA-KD was founded when influencers had already grown and had a major impact. Following thesis will be in Swedish.

This thesis deals with practical implementation of photon mapping algorithm. To achieve better results some basic and some more advanced methods of global illumination has been examined. These time demanding algorithms are often practically unusable and their further optimization is necessary. Optimized ray tracer is essential for practical implementation. Computing diffuse interreflection by Monte Carlo sampling is also very time demanding operation. Therefore it is appropriate to use it along with proper interpolation.

This study analyses the discursive construction of part-time employment and the workers in it in the employmentand legal contexts in Britain and Japan, applying an analytical framework of the law developed from a post-structuralist feminist viewpoint. In doing this, this study contributes to knowledge in the field of legal studies by providing an account of the active role of the law in the area of employment,through the operation of discourse, in shaping and reshaping structural inequality which part-time women employees face in contemporary British and Japanese society. Evidence for this study is collected from statistical data, questionnaires and interviews with managers, interviews with a group of ex-part-time women workers pursuing a legal case and the close reading of legal materials in the two countries. From the examination of these data, two discourses are identified,which circulate in employment and legal institutions in both countries and which help to produce the differentiation between full-time and part-time employees. One discourse emphasises differencesin labour-related factors, such as working hours, job content and commitment, while the other emphasises differences in the gendered characteristics and domestic positions of men and women. I show that the two discourses operate within and across these institutions, constructing part-time employment as different from and inferior to full-time employment on both labour related and gender-related grounds, and legitimisingthe disadvantaged position of part-time employees. This discursive construction has brought about a gendered hierarchy within the law in which the inferior working pattern of part-time employment is gendered as women's, while the superior pattern of full-time employmentis gendered as men's. On the basis of this analysis, I argue that the law is one of the most influential discursive mechanisms which bring about and help to sustain the hierarchical gendering of society, contributing to the production and reproduction of unequal power relations between the sexes and between employers and part-time women employees.

The thesis focuses on comparative criminal evidence law and sets out to explore whether it is possible to devise rules of criminal evidence that would suit different jurisdictions. This work should be treated as an exploratory project as it aims to find a suitable approach and then test it using three different rubrics of evidence law – evidence of prior convictions, hearsay evidence and standard of proof. Those rubrics in six different jurisdictions will be examined. The thesis first discusses the mainstream dichotomous approach to comparative criminal procedure and evidence, concluding that the inquisitorial-adversarial distinction has by today lost much of its descriptive power and was never meant to be a normative model. Instead, the author finds that all Western style jurisdictions today are concerned with accurate fact-finding and in order to facilitate accurate fact-finding, should take into consideration the cognitive needs and abilities of fact-finders. Since for the most part human cognition is universally the same, this psychology-based approach can serve as a foundation for evaluating the evidentiary regulation – and unless some extra-epistemic factors prevail, should guide legislatures towards optimizing and unifying their evidentiary regulation. Based on the recent studies in legal psychology, the author offers recommendations that would be workable in all sample jurisdictions. This is in part possible because empirical research tends to debunk often-held beliefs about professional judges being far superior fact-finders immune from the cognitive biases and emotional appeal usually attributed to jurors.

In this paper, I will share in detail the entire process of creating my thesis film, The Woodshed. I will cover each step from writing and pre-visualization to producing, directing, production design, cinematography, editing, and sound. I will mainly focus on the style of directing I employed and the key decisions I made as an editor to best tell my story. I will then evaluate my decisions to determine the success of the project.

This thesis has investigated the offence of robbery. Specifically, the semi-systematic review analysed commercial armed robbery, grouping offenders in terms of an apparent scale of professionalism to amateurism. Within armed robbery, target hardening strategies appear to have reduced opportunities for professionals, with a corresponding increase in amateur armed robbers fuelled by drug habits. The empirical study found that levels of interaction used by an offender with a victim increased with offender age. Interaction was lower for a robbery committed in an external location and for offenders with previous convictions for offences against the person and property. The violence facet could not be labelled as a specific discriminatory predictor. The findings from the research and semi-systematic review distinguished between two types of robbery offender; a career professional and an amateur antisocial robber. A career professional is older and more experienced, more likely to offend in a commercial location, commit the crime in a planned and controlled manner, use high levels of interaction and lower levels of violence. An amateur antisocial robber is more likely to commit an offence outside, have previous convictions for offences against the person and property and/or be under the influence of an illegal substance. The offence is likely to be opportunistic and chaotic, characterised by high levels of violence and low levels of interaction. The Inventory of Offender Risk, Needs and Strengths (IORNS) psychometric measure was analysed. It has the potential to provide an assessment of a robbery offender‟s ongoing treatment and risk management. However, it requires further validation and reliability analysis before it is deemed appropriate in doing so. The case study highlighted the impact of cannabis misuse on a robbery offender‟s behaviour pattern and mental illness. Implications for offender treatment needs, future therapeutic intervention and risk management are discussed along with the need for further validation of the proposed model.

This thesis will consider UK labour law’s role in promoting fairness for carers. Building upon Fineman’s work, I will argue that caring relationships are of vital importance to society and should be supported by the state. The principle of justice as fairness, substantiated by the capabilities approach, will underpin this argument. I will focus upon modifying the workplace through care centric labour laws to achieve fairness for carers. Care centric legislation, developed by Busby, focuses upon promoting carers’ rights to work, rather than workers’ rights to care. Much of the analysis will focus upon reconciliation legislation, which aims to support people providing care within the paid workplace. This is because it has been the main way successive UK governments have aimed to help people reconcile these competing commitments. Although this body of legislation has gone some way towards achieving this, I will show that it could have done more. To make labour law care centric, something more radical is required. In this regard, I will analyse a right to care. To conclude, I will highlight the need for more empirical work in this context to further understand how fairness for all carers could be achieved.
