Abstract:
Skeletal muscle specification and differentiation programs are regulated by the myogenic regulatory factors which include Myf5, MyoD, myogenin and Mrf4. Upstream of the MRFs, the transcription co-activators and other intracellular and extracellular signals play crucial roles in regulating skeletal myogenesis. Histone acetyltransferase activity of p300 is required for Myf5 and MyoD expression. Furthermore, the MyoD core enhancer region is indispensable for MyoD expression. However, the mechanism by which p300 activates MyoD gene expression is to be determined. The histone acetyltransferase activity of p300 can be inhibited by small molecule inhibitors such as curcumin. Thus, using the inhibitor approach on stem cells is useful to investigate the role of p300 in activating MyoD expression during myogenesis. We here show that curcumin was able to inhibit stem cell determination and differentiation into skeletal myocytes. We also show that p300 is present, and histone acetylation is high at the core enhancer region. Therefore, we provide evidence that p300 is directly involved in MyoD gene expression during skeletal myogenesis.

Abstract:
The school environment is often the focus of healthy eating and physical activity policies intended to address childhood obesity. However, students are usually excluded from the development and implementation of such policies. The purpose of this study was to explore grade nine student perspectives regarding: supports and barriers to healthy eating and physical activity at school; strategies for improving the school nutrition and physical activity environments; and potential student contribution to the development, implementation, and evaluation of school-based policies. A qualitative approach utilizing focus groups and photovoice with 30 students from two schools in southern Alberta was used to collect data. Major themes included: access to healthy food choices; teacher influences; peer influences; access to physical activity opportunities; impact of marketing; and conflicting messages. Students can provide valuable insights to policy development, implementation and evaluation. Implications for future research and policy development are reviewed.

Abstract:
Gestillte Kinder sind über die Muttermilch mit persistenten organischen Schadstoffen (POPs) belastet. Tierexperimentelle Studien deuten auf eine besondere Empfindlichkeit des sich entwickelnden Immunsystems für POPs hin. Mögliche Effekte dieser Verbindungen auf den kindlichen Organismus sind bisher kaum untersucht. Es wurden potenzielle Einflüsse verschiedener POPs (PCDDs, PCDFs, PCBs, beta-HCH, HCB und pp-DDE) auf natürliche Killerzellen (NK-Zellen) und NK-Aktivität bei gestillten im Vergleich zu nicht gestillten Kindern untersucht. NK-Zellen sind eine Lymphozytensubpopulation (CD3-CD56/16+), die über ihre zytotoxische Aktivität allogene, virusinfizierte und maligne Zellen ohne vorherige Sensibilisierung töten kann. Es wurden 66 gesunde Kinder im Alter von 11-12 Monaten untersucht, davon waren 50 Kinder mindestens 4 Monate lang voll gestillt und 16 Kinder nicht gestillt. Aus einer Region mit bekannter erhöhter PCDD/PCDF-Belastung stammten 13 gestillte Kinder. Die NK-Zellzahlen wurden mittels Immunphänotypisierung am Durchflusszytometer bestimmt. Die Aktivität der NK-Zellen wurde mit einem nicht-radioaktiven, durchflusszytometrischen Zytotoxizitäts-Assay gemessen. Die POP-Konzentrationen im Blutfett der Probanden wurden kommerziell bestimmt. Weder bei den NK-Zellzahlen, noch bei der NK-Aktivität konnten zwischen den gestillten und nicht-gestillten Kindern signifikante Unterschiede im t-Test nachgewiesen werden. In Korrelationsanalysen zeigten sich keine signifikanten Einflüsse der POP-Konzentrationen auf NK-Zellzahlen und NK-Aktivität. Im Laufe der Untersuchung zeigte sich, dass der eingesetzte Zytotoxizitäts-Assay nur semiquantitative Daten lieferte. Die vorliegenden Ergebnisse und weitere Befunde bezüglich des Immunsystems der Probanden weisen darauf hin, dass die relativ hohe Belastung lange gestillter Säuglinge mit POPs nicht zu einer biologischen Wirkung im kindlichen Organismus führt. Angesichts der nachgewiesenen positiven Effekte des Stillens, kann diesbezüglich die bestehende Stillempfehlung bekräftigt werden.
Breast-fed infants are exposed to persistent organic pollutants (POPs) via breast milk. Animal studies indicate a special sensitivity of the maturing immune system to POPs. Possible effects of these compounds on the infantile organism are so far barely examined. Potential influences of several POPs (PCDDs, PCDFs, PCBs, beta-HCH, HCB and pp-DDE) on natural killer (NK) cells and NK activity of breast-fed infants in comparison to formula-fed infants were investigated. NK cells are a subset of lymphocytes (CD3-CD56/16+) that can kill allogeneic, virus-infected and malignant cells via their cytotoxic activity without prior sensitization. The study group consisted of 66 healthy infants examined at age 11 to 12 months, of which 50 infants were breast-fed and 16 infants were formula-fed. 13 breast-fed infants came from a region with known increased PCDD/PCDF-burden. Numbers of NK cells were measured by flow cytometric immunophenotyping. NK activity was analysed by a non-radioactive flow cytometric cytotoxicity assay. POP concentrations in the blood fat of the probands were calculated commercially. There were no significant differences between breast-fed and formula-fed infants concerning number and activity of NK cells in the t-test. Analysis of correlation showed no significant influences of POP concentrations on the number and activity of NK cells. In the course of the study the data obtained by the employed cytotoxicity assay proved to be only semiquantitative. The presented findings and further results concerning the immune system of the study subjects suggest that the relatively high burden of long-term breast-fed infants with POPs does not lead to a biological effect in the infantile organism. Regarding the proven positive effects of breast-feeding the existing recommendation to breastfeed can be encouraged.

"Ethyl pyruvate emerges as a safe and fast acting agent against Trypanosoma brucei by targeting pyruvate kinase activity."

Abstract:
Background: Human African Trypanosomiasis (HAT) also called sleeping sickness is an infectious disease in humans caused by an extracellular protozoan parasite. The disease, if left untreated, results in 100% mortality. Currently available drugs are full of severe drawbacks and fail to escape the fast development of trypanosoma resistance. Due to similarities in cell metabolism between cancerous tumors and trypanosoma cells, some of the current registered drugs against HAT have also been tested in cancer chemotherapy. Here we demonstrate for the first time that the simple ester, ethyl pyruvate, comprises such properties. Results: The current study covers the efficacy and corresponding target evaluation of ethyl pyruvate on T. brucei cell lines using a combination of biochemical techniques including cell proliferation assays, enzyme kinetics, phasecontrast microscopic video imaging and ex vivo toxicity tests. We have shown that ethyl pyruvate effectively kills trypanosomes most probably by net ATP depletion through inhibition of pyruvate kinase (Ki = 3.0±0.29 mM). The potential of ethyl pyruvate as a trypanocidal compound is also strengthened by its fast acting property, killing cells within three hours post exposure. This has been demonstrated using video imaging of live cells as well as concentration and time dependency experiments. Most importantly, ethyl pyruvate produces minimal side effects in human red cells and is known to easily cross the blood-brain-barrier. This makes it a promising candidate for effective treatment of the two clinical stages of sleeping sickness. Trypanosome drug-resistance tests indicate irreversible cell death and a low incidence of resistance development under experimental conditions. Conclusion: Our results present ethyl pyruvate as a safe and fast acting trypanocidal compound and show that it inhibits the enzyme pyruvate kinase. Competitive inhibition of this enzyme was found to cause ATP depletion and cell death. Due to its ability to easily cross the bloodbrain- barrier, ethyl pyruvate could be considered as new candidate agent to treat the hemolymphatic as well as neurological stages of sleeping sickness.

SAMMANFATTNING Bakgrund: Fysisk aktivitet främjar hälsan och medför positiva effekter för kroppen. Barns och ungdomars fysiska aktivitet påverkas av olika faktorer på individ- och omgivningsnivå. Faktorerna interagerar med varandra och påverkar den fysiska aktiviteten på olika sätt och i varierande grad, faktorerna kan delas in i olika system i den Ekologiska systemteorin. Det kan exempelvis handla om föräldrars och vänners attityder och hur den fysiska miljön är utformad. Syfte: Syftet med denna studie var att utifrån ett Ekologiskt systemteoretiskt perspektiv undersöka 20-åringars upplevelse av vilka faktorer som har haft betydelse för hur fysiskt aktiva de har varit från 11-års ålder fram till idag. Metod: Studien genomfördes med en kvalitativ design med induktiv ansats. Fem deltagare intervjuades utifrån en intervjuguide innehållande semistrukturerade frågor. Kvalitativ innehållsanalys användes för att analysera och tolka materialet. Resultat: Analysen resulterade i 4 kategorier med 14 underkategorier. Kategorierna blev: ”Engagemang i idrotten påverkas av inre känslor och yttre krav”, ”Att vara en del av gemenskapen”, ”Den fysiska miljön och de socioekonomiska förutsättningarnas inverkan” och ”Andra möjliga påverkande faktorer på utövande”. Slutsats: Resultatet visade att de faktorer som har störst påverkan finns inom micro- och exosystemen. Faktorerna varierar med åldern och innefattar främst föräldrar, vänner och tillgänglighet.
ABSTRACT Background: Physical activity promotes health, and will have positive effects for the body. Children and adolescents physical activity is influenced by different factors at individual and environmental level. The factors integrate with each other and affect the physical activity in different ways and can be divided into different systems according to the ecological systems theory. It could for example involve the attitudes of parents and friends and how the physical environment is designed. Aim: Based on Ecological systems theory the purpose of this study is to examine 20-yearolds experience of which factors that have had an impact on their physical activity from 11 years old until today. Method: The study was conducted with a qualitative design with inductive approach. Five participants were interviewed based on an interview guide containing semi-structured questions. Qualitative content analysis was used to analyze and interpret the material. Result: The analysis resulted in 4 categories with 14 subcategories. The categories were: "Involvement in sport is affected by internal feelings and external demands", "Being a part of the community", "The impact of physical environment and socioeconomic conditions" and "Other possible factors affecting the activity". Conclusion: The result showed that the factors with the greatest impact is within the micro and exosystems. The factors varies over time and focuses on parents, friends and availability.

Abstract:
I explore the relationships between hate group activity, community factors, and the likelihood of hate crime occurrence within a county area. I integrate considerations raised by Routine Activity and Social Control theorists as well as current hate crime literature to frame my concept of the hate manager, an agent of social control that utilizes hate crimes as a means of enacting extralegal self-help for hate groups. I explore the relationship between hate managers and hate crime by testing a model relating hate group activity and hate crime occurrences by location. Next, I correlate hate crime occurrences with hate group activity at the county level for the state of Virginia using public data. I find that a hate group's presence holds greater predictive power than nearly any other factor for hate crime likelihood. My findings illustrate the nature of hate crime as a means of social control; whereby hate groups act as a parochial order and maintain hierarchical relations between offenders and victims through means of disciplinary crimes. I conclude by outlining suggestions for future research into the role of the hate manager.
Master of Science
In my thesis, I ask the question of how hate groups methodically encourage where hate crimes occur. I do this by creating the concept of the hate manager. Hate managers are figures which influence would-be criminals into their illegal acts. They do this by stoking the fears necessary for them to act outside legal boundaries in reaction to some feeling of threat, an act known as self-help. Hate crimes, I argue, are a form of self-help where the feeling of threat is directed towards individuals belonging to some marginalized group. By looking at data collected by various agencies in the state of Virginia, I discover that the presence of a hate group in a county is a stronger predictor for such acts than any other factor for hate crime likelihood. By doing so, I demonstrate that hate crimes are a form of social control. That is, I argue that hate groups maintain a sense of order or ranking by means of illegal and disciplinary self-help in the form of hate crimes. I conclude my thesis by outlining suggestions for future exploration of the hate manager’s role.

Full text
Abstract:
Cette thèse a pour objectif de développer une méthode électrochimique permettant de cribler à haut débit des inhibiteurs d'enzymes. Pour cela, une enzyme cible a été sélectionnée pour son intérêt thérapeutique, la transcétolase (TK) : elle est impliquée dans de nombreuses pathologies (cancer, maladies neurodégénératives, diabète…) et dans la survie de certains parasites pathogènes. Afin de mesurer l'activité de la TK, deux systèmes rapporteurs ont été développés, à l'aide de plaques de criblage électrochimique (PCE) constituées de 96 électrodes indépendantes. Le premier système rapporteur repose sur un système bienzymatique nécessitant l'intervention d'une enzyme auxiliaire, la galactose oxydase (GAOx) sous forme libre ou immobilisée dans la laponite. Cette enzyme est capable d'oxyder les produits de réaction de la TK et de produire du peroxyde d'hydrogène. Le format 96 des PCE a permis d'optimiser rapidement la détection électrochimique par ampérométrie pulsée par intermittence (IPA) d'activité oxydase et seulement 10 minutes sont nécessaires pour réaliser 96 mesures simultanées. Parallèlement, afin d'exploiter au maximum le système à 96 électrodes, cette détection d'activité oxydase a également été réalisée, en 10 minutes par électrochimiluminescence. Cette méthode offre l'avantage d'être plus sensible et moins variable que par IPA, mais limite l'utilisation de matrice d'immobilisation d'enzymes. La GAOx a ensuite été utilisée pour mesurer l'activité TK, cependant, les conditions réactionnelles n'étant pas optimales en présence du système bienzymatique (TK-GAOx), des temps d'incubation longs sont nécessaires et sont peu adaptées au criblage d'inhibiteurs de la TK. Un second système rapporteur ne nécessitant plus d'enzyme auxiliaire et faisant intervenir uniquement un seul substrat de la TK a été optimisé. Ce système repose sur l'oxydation de l'intermédiaire réactionnel formé par la fixation du cofacteur (la thiamine pyrophosphate) et du substrat sur l'enzyme par le ferricyanure. Cette méthode permet de mesurer 96 activités TK en seulement 7 minutes et a aisément été utilisée pour cribler une bibliothèque de molécules. Le criblage de 1360 molécules a permis d'identifier un nouvel inhibiteur de cet enzyme, présentant une CI50 de 63 μM. Le système électrochimique a également été utilisé pour déterminer le mécanisme d'inhibition (non compétitive pure partielle) et la constante d'inhibition associée (3,4 μM). Ces résultats sont inédits dans le domaine de l'électrochimie et offrent un large éventail d'applications que ce soit pour le criblage d'activité enzymatiques ou d'inhibiteurs d'enzymes
This thesis focuses on the development of a new electrochemical method allowing the high throughputscreening of enzyme inhibitors. For this purpose, a target enzyme has been selected for its therapeutic interest,transketolase (TK): this enzyme is involved in many diseases (cancer, neurodegenerative diseases, diabetes ...) and inthe survival of pathogenic parasites. To measure TK activity, two reporter systems have been developed by usingelectrochemical plates, composed of 96 independent electrodes.The first one is based on a bienzymatic system, requiring the use of an auxiliary enzyme, galactose oxidase(GAOx), in its soluble form or immobilized in laponite. This enzyme is able to oxidize TK products and producehydrogen peroxide. The 96-well format allowed to quickly optimize the electrochemical detection of oxidase activityby intermittent pulse amperometry (IPA) of oxidase activity and only 10 minutes are required to perform 96simultaneous measurements. In parallel, in order to harness the 96-well electrochemical system, this detection ofoxidase activity was also carried out in 10 minutes using electrochemiluminescence. This method is more sensitiveand less variable than IPA but is limited to the use of soluble enzymes. However, the reaction conditions are notoptimal for the bienzymatic system (TK-GAOx): long incubation times are required and are poorly adapted for thescreening of TK inhibitors.A second reporter system no longer requiring an auxiliary enzyme and involving only one TK substrate hasbeen optimized. This system relies on the oxidation by ferricyanide of the reactional intermediate resulted of thebinding of the cofactor (thiamine pyrophosphate) and the substrate. This method allows to measure 96 TK activitiesin only 7 minutes and was easily used to screen an in-house chemical library. The screening of 1360 molecules leadto the identification of a new TK inhibitor with an IC50 of 63 μM. This electrochemical system was also used todetermine the mechanism of inhibition (partial non-competitive mechanism) and the associated inhibition constant(3.4 μM). These results are innovative in the field of electrochemistry and offer a wide range of applications forenzymatic activity screening or the screening of enzymes inhibitors

Abstract:
This research examines the relationship between race and exposure to online hate material. The utilization of websites, weblogs, newsgroups, online games, radio broadcasts, online newsletters and a myriad of other online platforms has proliferated race-based hate groups in the US (Shafer 2002). According to the Southern Poverty Law Center (SPLC), the number of hate groups has been on the rise since the 1990s and continues to gain momentum with the advent of social media (Potok 2017). Exposure to separatist ideologies has propelled these radical rightwing groups into the mainstream by way of social media platforms, as they are "the most active producers of online hate material" (Costello, Hawdon, Ratliff, and Grantham 2016: pg. 313). That dissemination of radical rightwing ideologies, such as white supremacy, racial purity and racial solidarity, exists is not enough in understanding what individuals are exposed to race-based hate ideologies in online platforms. Exposure is the key to understanding the growth of these race-based hate groups and ways of countering the efforts to disseminate radical rightwing ideologies due to its relationship to hate group emergence and persistence. More so, understanding how these groups target individuals and recruit through social networking sites can provide insight into exposure. Exposure to hate material aids groups in recruiting new members and victimizing potential targets. In the same manner, exposure to hate material is victimization of those who are exposed. In a sample collected by Costello et al. (2016a), of those exposed to hate material online nearly half centered on race. Thus, it is tantamount that research be conducted examining the role that race plays in determining who is exposed to hate material online, and how individuals react to hate material based on race. This dissertation will examine the importance of exposure to hate. Specifically, this dissertation will analyze survey data gathered from the Online Extremism Survey using logistic regression analysis and linear regression to understand exposure to hate material online and routine activity theory.

Abstract:
In what ways does the legal and political monitoring of “hate groups” and "hate group activities" benefit the American left? Possible victims of crimes? Law enforcement? The state? Specifically, in what ways does the Southern Poverty Law Center’s “hate map” challenge and/or reiterate relations of power and knowledge? This thesis offers a feminist critical analysis of hate group surveillance and the Southern Poverty Law Center’s mapping of hate. The Southern Poverty Law Center (SPLC) is a progressive legal advocacy group that aids in the surveillance of “hate groups” and legislation against “hate crimes.” I investigate the assumptions grounding the SPLC’s rhetorical use of the term “hate” and analyze their surveillance and mapping in order to add to the growing body of literature that that seeks to rethink the institution of whiteness and the relationship between progressive groups and law enforcement. The SPLC’s “Hate Map” offers a visualization of “hate” while simultaneously ignoring and obscuring racism. This thesis is meant to produce an alternative reading of this map and the SPLC’s hate group surveillance. Using a critical feminist framework that is intimately linked to critical race theory and anarchist criminology, I interrogate the SPLC’s methods of mapping and surveillance as well as their connection to law enforcement and governmentality. In analyzing SPLC’s “Hate Map” and their “Law Enforcement Resources” page, I contend that the SPLC's use of "hate" in lieu of racism is a reflection of their uncritical analysis of systematic racism and state violence associated with whiteness. While I recognize SPLC’s important role in combating crimes against marginalized groups through advocacy and legal aid, I contend that their rhetoric around “hate” and use of mapping and surveillance may potentially collude with governmentality and state violence against historically disenfranchised populations.

Abstract:
The pyrimidine biosynthetic pathway is essential and similar in all bacteria. The pathway from Pseudomonas is regulated by nucleotides which bind to the upstream region of the pyrBC’ gene complex. Work in our lab mapped the genes and showed that the pyrB and pyrC’ were part of an overlap complex. The Pseudomonas aeruginosa has one circular chromosome. A former Pseudomonas now called Burkholderia cepacia is similar to P. aeruginosa except that it contains three circular chromosomes (CI, CII, CIII) and one large plasmid. The primary chromosome named CI contains the pyrBC’. To our knowledge there has been no report of the activity of ATCase in Pseudomonas and contrasted with that of Burkholderia. Here, we compare the activity of ATCase in P. aeruginosa and B .cepacia. Cells of both organisms were grown in Pseudomonas minimal medium and in Enriched medium. The ATCase was extracted and partially purified from each sample. It is hypothesized that the B. cepacia has greater activity for ATCase than do the Pseudomonas.

Abstract:
“Affective Economies of Activism: Reimagining Anti-LGBTQ Hate Crime” is a critique of racism and misogyny within the contemporary LGBTQ movement. I argue that the mainstream LGBTQ movement’s narrow focus on street crimes against white gay men has resulted in a hyperreality that distracts us not only from the effects of the actual racialized violence that takes place, but also denies meaningful discussion of structural violence. This dissertation traces the origins of this exclusive and harmful discourse since the late 1960s with each chapter describing different forms of active resistance and possibilities for finding solutions today. I analyze publications gathered from special collections across the country; oral histories I conducted with activists in the South; documentary films; and queer online culture. My scholarship combines theory with everyday lived experience in order to bring social justice to the center of our field of vision. I do not only discuss and theorize about social justice, but also practice what I preach by engaging in archive activism and contributing to a grassroots LGBTQ history.

ABSTRACT

The purpose of the study was to examine, from the point of view of former research findings, what impact physical activity had on learning. I chose to make an explorative/inductive research, to get as much knowledge as possible from the studied presentation of problem, not to limit myself to a specific research theory. The result proved, that school personal and student experienced many positive effects from daily physical activities. The pupils were more pleased. There was more piece and quiet in the classroom. The ability of concentration increased. The social climate was more agreeable, and with this the developement of knowledge was inpacted. Most research scientists also talked about the importance of better self-reliance and good self-understanding as a result of physical activities. It was also mentioned, that the number of violation had decreased and that the results of the national test had improved. The conclusions were, that it was elementary that schoolboards considered, the alterations in Lpo- and Lpf 94 about daily physical activities, seriously. The leaders of the school area had to appropriate resources, that would make it possible for teachers, to make physical activities form an integral part of many subjects. To sum up, learning was impacted positively by physical activities, even if the reported results showed that further research would be needed.


SAMMANFATTNING

Syftet med studien var, att utifrån tidigare forskning, undersöka vilken påverkan fysisk aktivitet hade på lärande. Jag valde att göra en explorativ/induktiv undersökning, för att hämta så mycket kunskap som möjligt från det studerade problemområdet och inte begränsa mig till en specifik undersökningsteori. Resultatet visade, att skolans personal och elever upplevde många positiva effekter av daglig fysisk aktivitet. Eleverna var gladare. Det var lugnare i klassrummet. Koncentrationsförmågan ökade. Det sociala klimatet var behagligare, och med det påverkades kunskapsutvecklingen. De flesta forskare nämnde även betydelsen av ökat självförtroende och god självuppfattning, som resultat av fysisk aktivitet. Det framkom också, att antalet kränkningar hade minskat och att resultaten på de nationella proven hade blivit bättre. Slutsatser blev, att det var primärt att skolledning tog förändringarna, i Lpo och Lpf 94, om daglig fysisk aktivitet på allvar. Ledarna i skolans värld borde avsätta mer resurser, som möjliggör för lärare att ämnesintegrera fysisk aktivitet. Sammanfattningsvis, påverkades lärande positivt av fysisk aktivitet, även om resultaten som redovisades visade, att det krävdes ytterliggare forskning.

Abstract:
This thesis aims to investigate whether shopping is still a gendered activity in the 21st century. Past research in a number of social science disciplines with a focus on consumer affairs indicated that traditionally shopping was part of the woman’s domain and therefore it was seen as an activity only women engaged in. More current research has however suggested that shopping is no longer just a female activity, and asked for more research to be conducted into both male and female consumer behaviour. The present thesis focuses on recreational shopping and attempts to address the issue of male and female consumer behaviour by means of a multi-method approach. Chapter 1 summarises the background literature and provides the rationale for the research conducted in this thesis. Chapter 2 focuses on the methodological issues relating to the present studies provides a justification of each methodological approach used. Chapters 3 to 6 present the empirical work carried out for this thesis and Chapter 7 presents the conclusions drawn from the research carried out. In Chapter 3 we present an investigation of participants’ (27 men and 71 women) written accounts of past (good and bad) and ideal shopping experiences using thematic analysis. The findings show that women report higher overall shopping enjoyment than men, which is in agreement with previous research results. However, men and women describe similar obstacles and negative experiences that deter them from participating or wanting to participate in shopping activities, and they exhibit similar motivations when thinking about shopping. In contrast, all descriptions of ideal shopping experiences were highly idiosyncratic. The study presented in Chapter 4 explores the relationship between product involvement and shopping enjoyment. One hundred and seventy-four participants (69 men and 102 women) responded to an online questionnaire, which measured attitudes towards shopping in general and shopping in a high involvement situation. As in the previous study, the results showed that overall women reported much higher general shopping enjoyment than men. But when product involvement was high men reported a more positive attitude toward shopping than when just rating shopping in general. This suggests that the issue of gender differences in shopping enjoyment needed to be investigated further and that a more fine-grained approach to research in this area was required to explore the differences and similarities in the way that men and women approach this activity. In Chapter 5 we investigate potential differences and similarities in men and women’s conceptions of shopping. The first study in this chapter asked participants to list types of shopping or shopping activities as they came to mind and the second study utilised a free-sort task. Surprisingly, the results from the Chi-Square analysis of Study 3 and EXTREE and INDSCAL analysis of Study 4 showed that there are very few significant differences in how men and women view shopping. Thus, it seems both sexes appear to think about shopping in very similar (if not the same) ways. In order to address this question in more depth, the study presented in Chapter 6 took a different methodological approach. Here, a focus group study was carried out to explore what lies behind men and women’s conceptions of shopping. Three groups (N=19) of first year undergraduate students participated in focus groups and discussed what they thought and felt about shopping. Results showed that perceptions of what shopping is are very strong even amongst this group of young consumers. Finally, the results are reviewed in Chapter 7 together with their implications, limitations of the present research and possible future directions.

Abstract:
Syfte: Syftet med denna litteraturstudie var att genom en litteraturgranskning undersöka om ökad fysisk aktivitet har något samband med inlärningen och skolprestationerna hos barn i åldrarna 6-12 år. Metod: Litteratursökningen i databaserna CINAHL och Academic Search Elite resulterade i 15 artiklar som publicerats de senaste fem åren. Artiklarna har kvalitetsgranskats och därefter sammanställts. Resultat: Fysisk aktivitet i samband med inlärning har i ett flertal studier visat sig leda till positiva resultat genom snabbare svarstid, noggrannhet och uppmärksamhet. Barnen som deltog i aeroba aktiviteter blev mer uthålliga och kunde behålla fokus längre vid de kognitiva testerna. Det skolämne som en signifikant skillnad kunde utläsas i var matematik följt av stavning och läsning. Olika interventionsprogram för att främja barns fysiska aktivitet har visat en positiv effekt i skolresultat och kognitiva tester. Slutsats: Föreliggande litteraturstudie visar att en ökad fysisk aktivitet har en positiv inverkan på barns inlärning och skolresultat genom förbättrad koncentrationsförmåga och noggrannhet.

Abstract:
Afin de dépolluer et de réhabiliter les sols contaminés par des hydrocarbures aromatiques polycycliques (HAP), différentes techniques ont été développées durant les dernières décennies, mais leur impact sur les fonctions du sol est rarement pris en compte. L'objectif de ce travail était d'évaluer l'impact des traitements par oxydation chimique sur différents paramètres physico-chimiques et biologiques de terres contaminées aux HAP et de proposer des solutions pour restaurer le fonctionnement biologique des terres oxydées. Les différentes expérimentations de laboratoire et de terrain ont montré que l'efficacité des réactions d'oxydation chimique (réaction de Fenton et persulfate activé) sur la teneur en HAP dépendait de la disponibilité de la pollution et des propriétés physico-chimiques des terres. Par ailleurs, des processus d'acidification ont été observés sur des terres non carbonatées, altérant fortement et durablement les paramètres physico-chimiques et biologiques. Cette altération était plus forte après utilisation du persulfate activé, engendrant ainsi des pertes en éléments traces métalliques dans les eaux de percolations. L'apport de matériaux susceptibles d'augmenter le pH a permis la restauration des activités biologiques et la capacité des terres à supporter la végétation lorsque les terres ont fortement été acidifiées. L'association de traitements d'oxydation chimique et de refonctionnalisation pourrait présenter un moyen de réhabilitation efficace. Un indice, dont l'objectif était de représenter l'état du sol en fonction du poids accordé à différents paramètres, a été proposé et a permis d'évaluer les variations induites par les traitements d'oxydation et les procédés de refonctionnalisation
In order to clean up polycyclic aromatic hydrocarbon (PAH) contaminated soils, various techniques have been developed during the last decades, but their impact on soil functions was rarely considered. The objective of this study was to assess the impact of chemical oxidation treatments on different physico-chemical and biological parameters of PAH contaminated soil and to propose solutions to improve the biological functioning of oxidized soil. Various laboratory and field experiments have shown that the efficiency of chemical oxidation reactions (Fenton reaction and activated persulfate) on PAH concentrations depended on pollutant availability and soil physico-chemical properties. Besides, intense acidification processes have been observed on uncarbonated soil with a strong impact on soil physico-chemical and biological parameters. Moreover, this alteration was higher with activated persulfate treatment, leading to the loss of trace metals in water percolation. In the strongly acidified soil, the input of materials, suitable for pH increase, resulted in the restoration of biological activities and soil capacity to support vegetation. The association of chemical oxidation treatment and restoration techniques could present a good mean for soil rehabilitation. Finally, an index, which aimed to represent soil conditions based on the weight given to different parameters, was proposed and was used to evaluate changes induced by oxidation treatments and restoration techniques

Ancient Chinese herbal texts as far back as the 4th Century Zhou hou bei ji fang describe methods for the use of Qing Hao (Artemisia annua) for the treatment of intermittent fevers. Today, the A. annua constituent artemisinin is an important antimalarial drug and the herb itself is being grown and used locally for malaria treatment although this practice is controversial. Here we show that the ancient Chinese methods that involved either soaking, (followed by wringing) or pounding, (followed by squeezing) the fresh herb are more effective in producing artemisinin-rich extracts than the usual current method of preparing herbal teas from the dried herb. The concentrations of artemisinin in the extracts was up to 20-fold higher than that in a herbal tea prepared from the dried herb, but the amount of total artemisinin extracted by the Chinese methods was much less than that removed in the herbal tea. While both extracts exhibited potent in vitro activities against Plasmodium falciparum, only the pounded juice contained sufficient artemisinin to suppress parasitaemia in P. berghei infected mice. The implications of these results are discussed in the context of malaria treatment using A. annua infusions.

Abstract:
Les Archaea planctoniques contribuent de façon significative aux grands cycles biogéochimiques dans les écosystèmes aquatiques, néanmoins la structure des communautés actives ainsi que leurs variations saisonnières sont encore largement méconnues. En outre, la découverte de l’implication des Archaea dans le cycle de l’azote (Ammonia Oxidizing Archaea ou AOA), plus particulièrement dans le processus de nitrification a considérablement modifié la perception d’un processus autotrophe réalisé uniquement par des bactéries (Ammonia Oxidizing Bacteria ou AOB). Dans les écosystèmes marins, la large distribution des AOA suggère que ces microorganismes joueraient un rôle prépondérant dans le cycle de l’azote néanmoins, ces observations ne sont pas généralisables à l’ensemble des écosystèmes aquatiques en raison de leur grande diversité et/ou d'un manque d'informations et d’études sur certains d'entre eux. Ainsi, les objectifs de ce projet étaient i) d’étudier la structure spatiale et temporelle des communautés d’Archaea actives dans des écosystèmes aquatiques contrastés en termes d’apports anthropiques et/ou de gradients de salinité (lac, estuaire, milieu côtier) ; ii) de déterminer la contribution relative des Archaea au processus d’oxydation de l’ammonium, en comparaison avec celle des bactéries ; et iii) de mieux comprendre les paramètres environnementaux qui pourraient déterminer l’établissement des communautés d’AOA ou d’AOB
Aquatic Archaea are important players among microbial plankton and significantly contribute to biogeochemical cycles, especially nitrogen, but details regarding their community structure and seasonal activity and dynamics remain largely unexplored. In marine ecosystems, the widespread distribution of Ammonia Oxidizing Archaea (AOA) suggests that they probably play a major role in nutrients cycling. However, we cannot generalize these observations to all aquatic ecosystems because of their high diversity and/or a lack of information and studies on these organisms for some of these ecosystems. More precisely, lacustrine and coastal ecosystems were less studied while they are potentially subjected to strong anthropogenic impacts. Moreover, notable differences in terms of diversity and activity between marine and freshwater communities can be expected, considering the specific environmental parameters of each ecosystem. The objectives of this thesis were: i) to study the archaeal community structure across a temporal scale and assess the diversity of archaeal communities and AOA in diverse aquatic ecosystems along anthropogenic and/or salinity gradient (lacustrine, estuarine and coastal ecosystems); ii) to determine their relative contribution in ammonia oxidation, compared to Ammonia Oxidizing Bacteria (AOB) by looking at their spatial and temporal distribution and activity, and iii) to explore more precisely the environmental parameters that could drive AOA and/or AOB establishment

Abstract:
The racial violence between Navajos and whites in Farmington, New Mexico is historical. One of the first documented acts of racial violence was in 1875, when white settlers would take gunshots at Navajos for entertainment. This violent atmosphere continued throughout the years, and most notoriously in 1974 with the murders of three Navajo men by three white teenagers. This violence was part of an ongoing cycle of racism and hostility between Navajos and whites. The murders ignited local and national media frenzy, and Farmington was dubbed the "Selma, Alabama of the Southwest." Navajo citizens responded to the murders with activism and demonstrations in the streets of Farmington, and demanded justice and change. Throughout subsequent years, racism and racial violence continues and Navajos are still the targets of hate crimes. The purpose of this study is to examine and investigate the hate crimes that have been committed against Navajo people in Farmington and its neighboring towns. This study, in particular, analyzes the impacts that hate crime has on Navajo citizens. Interviews with Navajo victims of hate crime expand on the findings of a pilot interview. The research in this dissertation shows that the affects of hate crime are long lasting and impact not only the victims but also the entire Navajo Nation. As a result of the unrelenting hate crimes in Farmington, the Navajo Nation has created a human rights commission to investigate race relations in Navajo Nation border towns. This study addresses what steps the Navajo Nation and Navajo citizens have taken to combat and recover from racism and racial violence. Finally, this study proposes interventions to improve race relations.

Abstract:

Syftet med studien var att undersöka om studenter tror att deras fysiska aktivitetsnivå idag påverkats av ett medlemskap i en idrottsförening som barn, samt ta reda på deras egen upplevda aktivitetsnivå idag. Det är en kvalitativ deskriptiv undersökning och därför var intervjuer den mest lämpliga metoden att använda. Individuella intervjuer gjordes med tretton studenter på en högskola. Det framkom i resultatet att deltagarna hade inställningen att den fysiska aktivitetsnivån som äldre, kunde ha påverkats av ett medlemskap i en idrottsförening som barn och unga. Detta troddes bero på bland annat den positiva känsla som idrottande gav och som gjorde att fysisk aktivitet upplevdes som något bra och roligt. Även andra saker spelade in som sammanhållningen som fanns vid idrottande. Detta var i sin tur en orsak till att en positiv känslan för fysisk aktivitet infann sig. Det gick även att urskilja ett mönster mellan tidigare idrotter och hur deltagarna motionerade idag. De som till exempel spelat fotboll som yngre, använde det som en motionsform även idag, detta skedde både på eget organiserade träffar med vänner men också som träffar som var organiserade av utomstående.


The purpose of this study was to examine whether students' memberships in sports clubs has affected their attitudes towards physical activity and physical activity level. It was a qualitative descriptive survey based on individual interviews. Results showed that there was a pattern between the former sports membership and current patterns of physical activity.  For instance, those who liked playing football at a young age, continue to adopt the same type of exercise today. This pattern applies to other types of physical activity, with or without club membership. In addition, many respondents thought that a club membership at a young age could have an impact on their physical activity as adults. This was mainly due to the positive feeling that sportsmen perception, that physical activity was something good and fun. Social cohesion in sport was the one thing that many of those interviewed believed was a major reason why sports, was perceived as positive.

Abstract:
Dagens föränderliga samhälle ställer höga krav på organisationers anpassningsförmåga vilket i sin tur kräver att utformningen av arbetsplatser ska kunna möta denna föränderlighet. Ett kontorskoncept som vinner mark på alltfler svenska företag är det aktivitetsbaserade konceptet. På en aktivitetsbaserad arbetsplats, som är uppbyggd efter olika zoner, ska medarbetarna kunna välja plats som stödjer den arbetsuppgift som för tillfället utförs. Fördelarna med dessa arbetsplatser framförs vara minskad lokalyta, ökad kommunikation samt större produktivitet. Syftet med denna uppsats är att få en förståelse för hur medarbetarna i en offentlig organisation upplever den aktivitetsbaserade arbetsplatsen. Vidare vill vi undersöka om avsikten med införandet av det nya kontorskonceptet har infriats i medarbetarnas upplevelser. Undersökningen genomfördes på Kungälvs stadshus som nyligen har börjat arbeta aktivitetsbaserat. Undersökningen har en kvalitativ ansats där intervjuer och observationer har genomförts. De framträdande slutsatserna i undersökningen visar att respondenternas upplevelser av arbetsplatsen, i de flesta fall, inte var kopplade till det aktivitetsbaserade kontorskonceptet som sådant, utan istället till den fysiska miljön. Flertalet upplevde att arbetsplatsen fungerade bra i förhållande till deras arbete. Däremot framkom att upplevelsen av arbetsplatsen skiljde sig något åt beroende på respondenternas uppdrag. Det framkom även att medarbetarna inte utnyttjade arbetsplatsens alla resurser och var begränsade i sin rörlighet. Vidare infriades vissa av avsikterna med införandet av kontorskonceptet i respondenternas upplevelser, medan vissa inte gjorde det. Denna undersöknings värde ligger i att det forskningsaktuella läget är begränsat och att de flesta studier som gjorts på området är kvantitativt riktade. Vidare belyser undersökningen, det allt för sällan undersökta, medarbetarperspektivet.
Today’s changeable society requires a great deal of organizations adaptability which in turn puts high demands on the office design to meet this changeability. An office concept that is attaining more attention from Swedish organizations is the activity-based concept. At an activity-based workplace, which is made up by different activity-areas, the employee can choose a workstation that best supports the activity at hand. Some of the uttered pros of activity-based workplaces are the decrease in use of office space as well as the increase in communication and productivity. The purpose of this research is to receive an understanding for the employee’s experience of the activity-based workplace, in a public organization. We will furthermore view if the intentions with the implementation, of the office concept, are shown in the employees’ experiences. The research was carried out at Kungälvs stadshus who just recently started working activity-based. Interviews and observations, with a qualitative approach, were carried out. The major findings of this research was that the respondents experiences of the workplace, in most cases, weren’t connected to the activity-based concept as such. Instead it was connected to the physical environment. The majority of the respondents experienced that the workplace supported them in their work. However, the experiences differed some, due to the employee’s assignment. Another finding was that the employees didn’t use all the resources in the workplace and was restricted in their mobility. Further the research shows that some of the intentions, with the implementation of the office concept, are shown in the employees’ experiences and some of the intentions are not shown. The value of this research lies in the fact that the research in this area is limited and the research that exists is done with a quantitative approach. Furthermore, the research illuminates the, all too rarely researched employee-perspective.

Abstract:
Den här studien undersöker möjligheten att använda sig utav Human Activity Recognition (HAR) i ett mobilspel, Bamblup, som använder sig utav fysiska rörelser för att upptäcka om en spelare fuskar eller om denne verkligen utför den verkliga aktiviteten. Sensordata från en accelerometer och ett gyroskop i en iPhone 7 användes för att samla data från olika människor som utförde ett antal aktiviteter utav intresse. Aktiviteterna som är utav intresse är hopp, knäböj, stampa och deras fuskmotsvarigheter, fuskhopp, fuskknäböj och fuskstampa. En sekventiell modell skapades med hjälp av det öppna programvarubiblioteket, TensorFlow. Feature Selection gjordes i programmet WEKA (Waikato Environment for Knowledge Analysis), för att välja ut attributen som var mest relevanta för klassificeringen. Dessa attribut användes för att träna modellen i TensorFlow, vilken gav en klassificeringsprecision på 66%. Fuskaktiviteterna klassificerades relativt bra, och det gjorde även stampaktiviteten. Hopp och knäböj hade lägst klassificeringsprecision med 21.43% respektive 28.57%. Dessutom testades Random Forest klassificeraren i WEKA på vårt dataset med 10-delad korsvalidering, vilket gav en klassifieringsnoggranhet på 90.47%. Våra resultat tyder på att maskininlärning är en stark kandidat för att hjälpa till att identifiera fuskbeteenden inom fysisk aktivitetsbaserade mobilspel.
This study investigates the possibility to use machine learning for Human Activity Recognition (HAR) in Bamblup, a physical activity-based game for smartphones, in order to detect whether a player is cheating or is indeed performing the required activity. Sensor data from an accelerometer and a gyroscope from an iPhone 7 was used to gather data from various people performing a set of activities. The activities of interest are jumping, squatting, stomping, and their cheating counterparts, fake jumping, fake squatting, and fake stomping. A Sequential model was created using the free open-source library TensorFlow. Feature Selection was performed using the program WEKA (Waikato Environment for Knowledge Analysis), to select the attributes which provided the most information gain. These attributes were subsequently used to train the model in TensorFlow, which gave a classification accuracy of 66%. The fake activities were classified relatively well, and so was the stomping activity. Jumping and squatting had the lowest accuracy of 21.43% and 28.57% respectively. Additionally, the Random Forest classifier in WEKA was tested on the dataset using 10-fold cross validation, providing a classification accuracy of 90.47%. Our findings imply that machine learning is a strong candidate for aiding in the detection of cheating behaviours in mobile physical activity-based games.

Denna studie har studerat äldre individers sömn samt fysisk aktivitet förhållande till arbetsminne. Syftet med studien var att undersöka om det existerar ett samband mellan dessa. Frågeställningarna var om fysisk aktivitet påverkar arbetsminnet hos äldre människor och om sömn är en bidragande faktor till bättre arbetsminne. Datamängden för studien bestod av totalt 181 individer som var mellan 50-75 år. Metoden som användes i undersökningen var ett kvantitativt enkätformulär samt tre olika tester av deltagarnas arbetsminne. Statistisk analys av insamlad data genomfördes med hjälp av programmet SPSS. Resultatet visade ett signifikant samband mellan deltagarnas ålder och arbetsminne. Utbildningsnivå var även något som påverkade resultatet på arbetsminnestesterna för deltagarna. Dessvärre kunde slutsatsen dras om att sömn inte var positivt relaterat till arbetsminne. Ytterligare en slutsats var att fysisk aktivitet och ålder hade en korrelation men inget orsakssamband till deltagarnas arbetsminneprestation kunde förklaras.
This study has examined the sleep of older individuals as well as physical activity in relation to working memory. The aim of the study was to investigate whether a relationship exists between them. The research questions were whether physical activity affects the working memory of older people and whether sleep is a contributing factor to better working memory. Data set for the study consisted of a total of 181 individuals who were between 50-75 years old. The method used in the study was a quantitative questionnaire and three different tests of the participants working memory. Statistical analysis of data collected was carried out using the SPSS program. Results showed a significant relationship between the participants age and working memory. Level of education was also something that affected the results of the working memory tests for the participants. Unfortunately, it could be concluded that sleep was not positively related to working memory. Another conclusion was that physical activity and age had a correlation but no causal relationship to participants working memory performance that could be explained.

Abstract:
L'activité physique et l’alimentation participent à la régulation de l'horloge biologique et du sommeil. Récemment, ce sujet a suscité l’intérêt de plusieurs recherches. Cependant, les études restent presque exclusivement limitées aux adultes. L'adolescence est une période charnière de la vie pendant laquelle plusieurs troubles du sommeil émergent. L'obésité et le sport d'élite sont deux facteurs qui ont été associés séparément aux perturbations du sommeil et qui ont un impact négatif sur le développement holistique, avec une baisse des performances et une altération de l'état de santé des adolescents, tant physique (récupération, métabolisme, croissance, contrôle du poids) que cognitif (apprentissage, mémoire, prise de décision, vigilance). Par conséquent, le but de ce travail était d'explorer l'effet de l'activité physique et de la nutrition sur le sommeil parmi ces deux populations distinctes d'adolescents. L'altération des habitudes de sommeil chez les jeunes athlètes semble être davantage liée aux contraintes sportives telles que la compétition et les voyages. Cependant, l'exercice physique aigu améliore la qualité de la durée du sommeil dans les deux populations (athlète et obèse). De plus, l'alimentation semble être une alternative prometteuse pour améliorer la qualité du sommeil. Seuls trois jours d'alimentation contrôlée, fixés à l'apport alimentaire recommandé, ont permis de réduire le temps d’endormissement chez les adolescents obèses par rapport à la condition ad libitum. Enfin, des études contrôlées randomisées sont nécessaires pour étayer l'effet de certains nutriments sur le sommeil. L'étude PROTMORPHEUS permettra de mieux comprendre l'effet du rapport Trp/AAN des protéines sur le sommeil
Physical activity and ingested nutrients take part in the regulation of the internal clock andsleep physiology. Recently, there has been a surge of interest in this topic. However, studiesremain almost exclusively limited to adults. Adolescence is marked by critical transitionsthat may trigger several behavioral disturbances particularly with regard to sleep. A problemcompounded by an array of endogenous and exogenous factors forming the so called“Perfect Storm” of both altered sleep duration and quality. Obesity and elite sport are twofactors that have been separately associated with sleep disturbances, and have a negativeimpact on holistic development, with lowered performance and altered health status ofadolescents, both physical (recovery, metabolism, growth, weight control) and cognitive(learning, memory, decision-making, vigilance). Therefore, the purpose of this work was toexplore the effect of physical activity and nutrition on sleep among these two distinctadolescent populations. Altered sleep pattern in young athletes seems to be more related tosport constraints such as competition and travel. However, acute exercise improves sleepduration in quality in both populations (athlete and with obesity). Moreover, dietary intakeseems to be a promising alternative to improve sleep quality. Only three days undercontrolled feeding fixed at the recommended dietary allowance resulted in reduced sleeponset latency in adolescents with obesity compared to ad-libitum condition. Finally,randomized controlled studies are needed to support the effect of certain nutrients on sleep.PROTMORPHEUS study will bring a fuller understanding of the effect of proteintryptophan/large neutral amino acids ratio on sleep

Abstract:
Les méthodes de criblage haut-débit sur des cellules nécessitent de petits volumes afin de réduire les coûts et permettre une manipulation rapide des échantillons. En effet, une miniaturisation supplémentaire des technologies classiques de criblage haut-débit en plaques devient problématique à cause de l’évaporation et des forces capillaires. Pour surmonter ces limitations, on a développé des systèmes basés sur la microfluidique en gouttes où des cellules sont cultivées dans des microcompartiments aqueux indépendants entourés d’huile perfluorée inerte. Un tel système permet d’effectuer des analyses automatisées à l’échelle individuelle de chaque compartiment suite à un certain temps d’incubation comme le requiert les tests cellulaires à haut-débit. Nous nous sommes focalisés également sur le développement de tests fonctionnels pour le criblage d’anticorps comme par exemple les anticorps neutralisants le VIH (Virus de l’Immunodéficience Humaine) ou inhibant l’ECA (Enzyme de Conversion de l’Angiotensine). Les approches haut-débit pour la sélection d’anticorps utilisent le « phage display » ou des hybridomes. « Phage display » est une méthode efficace mais permet de sélectionner les anticorps pour leur activité de liaison et non pas de neutralisation. Les hybridomes permettent d’effectuer une sélection en fonction de l’activité neutralisante des anticorps, mais dans cette approche on est limité par le nombre de clones pouvant être sélectionnés. Le but de ce projet était d’établir un nouveau test permettant de sélectionner, au niveau de cellules uniques, des cellules sécrétrices d’anticorps (hybridomes). Ce système pourra être utilisé également pour le criblage de cellules B. Une fois établi, ce système pourrait être utilisé pour le criblage/sélection de beaucoup d’autres anticorps thérapeutiques
High-throughput, cell-based assays require small sample volumes to reduce assay costs and to allow for rapid sample manipulation. However, further miniaturisation of conventional microtiter plate technology is problematic due to evaporation and capillary action. To overcome these limitations, we developed droplet-based microfluidic platforms in which cells are grown in aqueous microcompartments separated by an inert perfluorocarbon carrier oil. Furthermore, this system allowed for an automated analysis of individual compartments subsequent to an incubation period as required for high-throughput, cell-based assays. In addition, we focused on the development of functional assays for screening antibody activity, e. G. Neutralisation of HIV or the inhibition of ACE-1. Common high throughput approaches for antibody screening use phage display or hybridoma cells. Phage display is powerful but based on binding properties rather than neutralising effects. Hybridoma cells allow for direct screening of neutralising activity, but are very restricted in the number of clones that can be screened due to their generation and proliferation as required for conventional screens. The aim of this study was the development of novel screening technology with the ultimate goal of screening single antibody-releasing cells (hybridoma cells). This system should also allow for direct B-cell screening. Once established, this technology could be used for the screening/ selection of many more therapeutic antibodies

Abstract:
Industrial processes have for a long time become more and more automated, this is no different in the mining industry. When excavating during mining operations special drill rigs are used to drill holes in the rock walls to be used for either explosives or bolts to support the structure. The study aimed to find out if it was possible to create an algorithm that would use the drill rigs telemetry data to estimate the number of holes it had created over specific time period. The main approach would be to see if machine learning could be used for the problem or if some other method could be theorised. Without the groundwork needed to create a proper machine learning algorithm a basic statistical approach was used to solve the problem, however since there were no actual reports containing the amount of holes a rig drilled the final solution is highly conjectural.

Abstract:
The objective of this qualitative study was to contribute to the understanding of how musical activities affect the participants' well-being and empowerment and to investigate which fac-tors contribute to that effect. Invitations were sent to 13 adult participants in a rock music school in the middle part of Sweden. 7 persons (4 men, 3 women) participated in the study. 4 themes were discussed in focus groups to highlight how informants were affected by the ac-tivity and what factors were important in the context. Results showed that music activities impact on participants' well-being and empowerment through several factors.Themes that appeared were: 1) focus on the present through music, 2) personal development, 3) meaningful leisure activity 4) the group properties. The group properties theme had four underlying themes: participation, equality, tolerance, cooperation toward common goals and leadership. The study has led to a greater understanding of how musical activities affect indi-vidual well-being and empowerment. A visualization of the participating forces that play a role in this effect has started and extended research with more suitable methods is needed to illuminate the individual factors and how they contribute to individual well-being and em-powerment.
Syftet med denna kvalitativa studie var att bidra till förståelsen om hur en musikgruppsverk-samhet kan inverka på deltagarnas välbefinnande och empowerment samt att undersöka vad i sammanhanget som kan ge upphov till denna inverkan.Missivbrev skickades till 13 vuxna deltagare i en rockmusikskola i mellersta Sverige och 7 personer (4 män, 3 kvinnor) deltog sedan i studien. 4 teman diskuterades i fokusgrupper i en strävan att synliggöra hur informanterna berörts av verksamheten samt vilka faktorer som varit betydelsefulla i sammanhanget. Transkriberingen av intervjuerna analyserades sedan genom att meningsbärande enheter plockades ut, kodades och delades upp i teman.Resultaten visade att en rockgruppsverksamhet har inverkan på deltagarnas välbefinnande och empowerment genom ett samlad inverkan av flera faktorer. De teman som framkom i fokus-grupperna med betydelse för denna inverkan är 1) fokus på nuet genom musiken, 2) personlig utveckling, 3) meningsfull fritidssysselsättning samt 4) gruppens egenskaper och under detta tema fanns fyra underliggande teman; delaktighet, likvärdighet, tolerans, samarbete mot ge-mensamt mål och ledarskapet. Studien har lett fram till en ökad förståelse om hur en musik-gruppsverksamhet inverkar på individers välbefinnande och empowerment. Ett avstamp till att synliggöra de medverkande krafterna som har en roll i denna inverkan har påbörjats och det behövs mer forskning med bättre lämpade metoder för att mer ingående belysa fenomenet

Abstract:
L'objectif de ces travaux était d'utiliser certains aspects de l'activité chimique et photochimique de télomères fluorés porteurs de fonctions azides, dans le but de promouvoir les synthèses de polymères thermostables et de nouveaux matériaux photoréticulés. En premier lieu, nous avons développé et caractérisé une nouvelle classe de poly(alkyl-aryl) éthers par une promotion de la compétition de la réaction de « Click » et de couplage de Hay. Par la suite, l'activité photochimique de ces composés fluorés a été étudiée et utilisée pour élaborer des matériaux photoréticulés. Les énergies libres des surfaces des films obtenus ont été calculées en utilisant le modèle d'Owens et Wendt. Les rugosités et les compositions de ces surfaces présentant des mouillabilités singulières ont été investiguées par le biais d'analyses par profilométrie, AFM et EDX. En dernier lieu, les synthèses et caractérisations de réseaux photoréticulés sont abordées. La post sulfonation de ces matériaux a conduit à la préparation de nouveaux électrolytes pour l'application pile à combustible dont les microstructures et propriétés physico-chimiques ont été étudiées
This work aims at using both chemical and photochemical activities of fluorinated telomers bearing azido end groups, to promote the synthesis of thermostable macromolecules and original photocrosslinked networks. In a first part, we have prepared and characterized a novel class of linear poly(alkyl aryl) ethers by the promotion of competitive “Click” reaction and Hay coupling. Then, the photolysis under UV irradiation of these fluorinated polymers was studied and used to generate photocrosslinked materials. The surface free energies of the resulting films were established using the Owens-Wendt model. The roughness and composition of the surfaces were investigated by profilometry, AFM and EDX analysis. Finally, the preparation under UV irradiation of original polymer networks was performed. The post-sulfonation of these materials allowed to prepare new proton exchange membranes for fuel cells application. The microstructures, physical and chemical properties of these electrolytes were investigated

Abstract:
Syftet med denna undersökning är att undersöka hur glanceable feedback kan implementeras i aktivitetsenheter för hundar för att skapa en bättre användarupplevelse och minska den teknologiska störningen i kommunikationen mellan människa och hund. Tidigare studier visar att utvecklingen hos aktivitetsenheter för hundar är långt ifrån lika framgångsrik jämfört med den för aktivitetsenheter för människor (Ramokapane, van der Linden & Zamansky, 2019; Väätäjä et al. 2018; Zamansky; et al. 2019). Väätäjä, et al. (2018) har påpekat vikten av att teknologin bakom aktivitetsenheten, så som mobiltelefoner, inte ska komma mellan hundägaren och hunden. Den får inte agera som ett störningsmoment som distanserar kommunikation eller interaktion mellan hund och människa (Väätäjä et al. 2018). Detta är idag oundvikligt i dagens aktivitetsenheter för hundar då användaren är helt beroende av mobiltelefonens tillhörande applikation (Väätäjä et al. 2018). Genom frågeställningen (Hur kan glanceable feedback appliceras i aktivitetsenhet för hundar för att ge hundägaren direkt information om hundens aktivitet?) undersöks hur glanceable feedback kan appliceras i aktivitetsenheter för hundar och undvika att kommunikation mellan hund och ägare störs med tekniken. Resultatet är aktivitetsenheten Good Boy. Enheten är försedd med en display och ett mekaniskt hjul som byter mellan de olika kategorierna distans/steg, puls/kroppstemperatur, info/kontaktuppgifter och led/lampa.
The purpose of this study is to investigate how glanceable feedback can be implemented in activity units for dogs to create a better user experience and reduce the technological disruption in human-dog communication. Previous studies show that the development of activity units for dogs is far from as successful as activity units for humans (Ramokapane, van der Linden & Zamansky, 2019; Väätäjä et al. 2018; Zamansky et al. 2019). Väätäjä, et al. (2018) have pointed out the importance of the technology behind the activity, such as the mobile phone, unit not coming between the dog owner and the dog. It must not act as a disturbance that distances communication or interaction between dog and human (Väätäjä et al. 2018). This is inevitable in today's activity units for dogs as the user is completely dependent on the mobile phone's associated application (Väätäjä et al. 2018).  The question (How can glanceable feedback be applied in an activity unit for dogs to give the dog owner direct information on the dog's activity?) Investigates how glanceable feedback can be applied in activity units for dogs and avoid that communication between dog and owner is disturbed by technology. The result is the Good Boy activity unit. The unit is equipped with a display and a mechanical wheel that switches between the different categories distance / step, pulse / body temperature, info /contact information and LED/lamp.

Full text
Abstract:
Cette thèse a démontré que les athlètes élites vivent en moyenne 7 ans de plus que la population générale, notamment en raison d’une réduction de 35 à 45% de la mortalité par maladies cardiovasculaires et par cancers. Ces résultats s’appuient sur l’analyse de l’ensemble des sportifs français (n= 3.600) ayant participé aux Jeux Olympiques depuis 1912 et au Tour de France depuis 1947. Des nouvelles méthodes en analyse de survie ont été mises au point pour investiguer ces cohortes qui ont la particularité de survivre mieux que leurs référents. A ces démonstrations s’ajoute le ralentissement de la progression de la longévité maximale humaine. Ce constat résulte de la comparaison des tendances de durée de vie de tous les olympiens depuis 1896 (n= 19.012) et des doyens de l’humanité (n= 1.205). Ces travaux répondent au besoin de mieux comprendre la relation dose-réponse de l’activité physique, médicament du 21ème siècle, en raison de son impact majeur sur la longévité des populations, ainsi qu’à l’intérêt d’explorer les marges d’augmentation possibles de cette longévité
Background and objectives: along their careers, elite athletes are subjected to specific constraints that distinguish them from the general population. Such constraints, related to the high intensity of their physical activity, their overexposure to injuries or particular lifestyle, may have long-term consequences on the athletes' health, and ultimately on their longevity. Thus, the main goals of the present study are the following: 1) to describe and analyze elite athletes’ longevity and specific causes of mortality in comparison with the general population and according to the type of effort they performed; and 2) to investigate their lifespan trends in comparison with the longest-lived humans in order to apprehend the current scenario of human longevity trends. Methods: we collected data on the biography and the athletic performances of all the French athletes who participated in the Olympic Games (OG) from 1912 to 2012 (n = 4708), and all the French cyclists who participated in the Tour de France (TDF) from 1947 to 2012 (n=786). Then, we verified their vital statuses through the National Registry of Identification of Physical Persons (RNIPP). For the deceased athletes, we obtained the causes of their deaths through the Centre for epidemiology on medical causes of death (CépiDc). We compared the athletes’ overall and specific mortality (according to the main chapters of the International Classification of Disease) with the French civilian life tables using Standardized Mortality Ratio (SMR) and the Kaplan-Meier methods. We adapted and applied the life years-lost method under the competing risk model to quantify differences on longevity due to major causes of death according to the athletes’ type of effort. Furthermore, we collected data on worldwide deceased Olympians participating in the OG from 1896 to 2012 (n=19 012) and on worldwide supercentenarians (>110 years) deceased between 1900 and 2013 (n= 1 205) in order to analyze their lifespan trends using a density analysis tool (total number of life durations per birth date). Findings and conclusion: French elite athletes show consistently lower mortality (≈40-50% lower) in comparison with their compatriots, whether female or male Olympians, or professional cyclists, mostly related with a lower cardiovascular (≈ 40-60% lower) and cancer mortality (≈ 45% lower). No excess mortality was observed in elite athletes for any of the specific causes of death we studied. French Olympians’ lower mortality results in an average of seven years of life saved in relation to the general population. This gain partitioned according to specific causes of deaths shows that cardiovascular longevity benefit is associated with the type of sports practiced during the Olympic career, favoring combined type of effort over very short- or very long-duration effort. In relation to cancer mortality, all types of effort studied were associated with better longevity. Despite their survival advantage, no Olympian in the world, up to date, has ever reached the status of a supercentenarian, as the longest-lived was 106 years old. The common lifespan trends between Olympians and supercentenarians indicate similar mortality pressures over both populations that increase with age, a scenario that is better explained by a biological “barrier” limiting further progression. The supercentenarians’ density trends show a current stagnation of the human longevity

ENGLISH ABSTRACT: Engagement in physical activity is a basic human right and has numerous benefits for mental well-being. Persons with disabilities are often denied this right due to a number of barriers existing on physiological, psychological and structural levels. Adolescents with motor impairments may be even further marginalised due to the physical nature of their impairment as well as being at a developmental stage where their opinions may not be taken into account based on their age. Research that has been conducted in this area has mostly focused on the accounts of parents and teachers with little voice being given to adolescents. This research aimed to explore the lived experiences of a group of adolescents with cerebral palsy (CP) and their involvement in physical activity. The sample group consisted of 15 adolescents with CP between the ages of 12 and 18 in the Western Cape. Semi-structured interviews were conducted with the participants. In addition, three staff members were interviewed in order to add a secondary layer of data to the study. The interviews were analysed using interpretative phenomenological analysis which aims to give voice to participants and to make meaning of these accounts through interpretation by the researcher. Five major themes emerged from the data, namely: (1) “When they call me cripple” – what it means to have a motor impairment, (2) My experience of physical activity – perceived benefits, facilitators and barriers to participation, (3) Protective factors and coping strategies employed by participants to overcome barriers to participation, (4) What I would like and what I recommend, and (5) Perceptions of staff members at the school. These themes were discussed through a theoretical framework focused on the psychological and social factors which influence an individual’s participation in (or avoidance of) physical activity. While this theoretical framework is based on able-bodied persons, it was interesting to compare the experiences of adolescents with CP. The findings were further discussed in comparison to the relevant literature, although the purpose of qualitative research is not to necessarily generalise findings. This discussion yielded similarities and differences in terms of experiences relating to barriers and facilitators to participation. In addition, the findings supported the notion that adolescents with disabilities know what they want and have valuable input to offer in terms of their own experiences. Recommendations include further studies being conducted with groups of adolescents with disabilities other than CP as well as in other areas of South Africa. This could give a more rounded understanding of the experiences of adolescents with disabilities and could better inform projects that could be developed.
AFRIKAANSE OPSOMMING: Betrokkenheid in fisiese aktiwiteit is ‘n basiese mensereg en het verskeie voordele vir verstandelike gesondheid. Mense wat gestremdhede het word dikwels ontken van hierdie reg, as gevolg van getalle struikelblokke wat bestaan op fisiologiese, sielkundige en strukturele vlakke. Adolessente met motoriese gestremdhede mag dalk nog meer gemarginaliseerde word as gevolg van die fisiese aard van hul gestremdheid, asook die feit dat hulle in ‘n ontwikkelings stadium is waar hulle opinie dalk nie in ag geneem word nie weens hulle ouderdom. Navorsing wat uitgevoer is in hierdie gebied het meestal gefokus op die mededeling van die ouers en onderwysers en het min stem gegee aan die adolessente self. Hierdie navorsing het daarop gemik om die beleefde ervaringe van ‘n groep adolessente met serebrale verlamming en hulle betrokkenheid in fisiese aktiwiteit te ondersoek. Die monster groep het bestaan uit 15 adolessente met serebrale verlamming tussen die ouderdomme van 12 en 18 in die Wes-Kaap. Semi- gestruktureerde onderhoude was gedoen met die deelnemers. Bykomend is daar ook onderhoude gedoen met drie personeellede om ‘n sekondêre vlak van data aan die studie te verleen. Die onderhoude was geanaliseer deur gebruik te maak van interpreterende fenomenologiese analise, wat daarop gemik is om ‘n stem te gee aan die deelnemers en om sin te maak van hulle beskrywinge deur interpretasie van die navorser. Vyf groot temas het na vore gekom uit die data, naamliks: (1) Wanneer hulle my verlam noem – wat dit beteken om ‘n motorise gestremdheid te hê, (2) My ondervinding van fisiese aktiwiteit – waargenome voordele, fasiliteerders en struikelblokke tot deelname, (3) Beskermende faktore en hanteringsvaardighede wat gebruik word deur die deelnemers om struikelblokke tot deelname te oorkom, (4) Waarvan ek sal hou en wat ek voorstel, en (5) Persepsies van personeellede by die skool. Hierdie temas was bespreek deur ‘n teoreties raamwerk wat gefokus is op die sielkundige en sosiale faktore wat ‘n individu se deelname aan (of vermyding van) fisiese aktiwiteit beïnvloed. Alhoewel hierdie teoretiese raamwerk gebaseer is op ongestremde persone, was dit interessant om die ondervindinge te vergelyk met adolessente met serebrale verlamming. Die bevindinge is verder bespreek in vergelyking met relevante literatuur, al is die doel van kwalitatiewe navorsing nie noodwendig om bevindinge te veralgemeen nie. Die bespreking het ooreenkomste, so wel as verskille ten opsigte van ondervindinge met betrekking tot hindernisse en fasiliteerders tot deelname opgelewer. Daarbenewens verleen die bevindinge ook ondersteuning aan die idee dat adolessente met gestremdhede weet wat hulle wil hê en dat hulle waardevolle insette het om te lewer in terme van hulle eie ervarings. Aanbevelings sluit in dat daar verdere studies gedoen moet word met ‘n groep adolessente wat ‘n gestremdheid anders as serebrale verlamming het, asook om verdere studies te doen in ander areas van Suid-Afrika. Dit sal ‘n meer afgeronde begrip van die ondervindinge van adolessente met gestremdhede lewer en sal ook beter instaat wees om projekte in te lig wat dalk ontwikkel mag word.

Abstract:
The main objective of this study was to determine which coping mechanisms have a higher impact on levels of stress in MSW graduate students. The distinctive aspect of this study was that the three primary points that were examined in MSW graduate students were spirituality, physical activity, and self-compassion. This study gathered quantitative data from students that were enrolled in the Master of Social Work program. There were a total of 102 participants in this study. A variety of bivariate analyses were conducted to assess the collected data. Significant outcomes from this study revealed that self-compassion was the best mitigator of stress levels. Spirituality was also found to be helpful in mitigating stress levels. Recommendations included the promotion of self-compassion in MSW graduate programs, along with agencies that provide additional training on self-compassion. Another important recommendation was for future studies to include date from other universities with MSW programs in order to expand and enrich the data.

Abstract:
Soaps operas, or daytime serials, have long been a staple of American culture. In April 2011, ABC-Disney announced the cancellation of All My Children and One Life to Live. Cancellations propelled the fans of these programs to launch efforts to save not only the shows, but the genre. Through the use of social media, websites, and traditional off-line activities that included calling and letter-writing, fans strived to make their voices heard. The study examines the creation of an online community and discourse through a textual-analysis case study of blogs on two fan activist websites. Dahlberg?s criteria for presence in an online public space and Habermas? public sphere allows for the presentation of ideas within a group to encourage a sense of democracy in a grassroots effort to be heard against corporate interests. The case study will examine a fan website, Sudz.Tv, as a group organized in a virtual public space.

Abstract:
Recent population studies provide evidence that individuals with high circulating insulin levels have a poor prognosis and/or increased risk of cancer development; however, laboratory studies concerning the role of insulin in breast cancer biology are sparse. We compared the growth of 4T1 murine breast cancer allografts in control mice, alloxan-induced hypoinsulinemic mice, and mice treated with the insulin/insulin-like growth factor-1 receptor tyrosine kinase inhibitor BMS-536924. Both interventions significantly decreased tumor growth versus control and decreased pathway activation downstream of the insulin receptor as reflected by Aktser473 phosphorylation status in the neoplastic tissue. Alloxan-treated mice exhibited signs of insulin deficiency, while BMS-536924-treated animals showed only minor metabolic derangements. Skeletal muscle displayed reduced pAktser473 in alloxan-treated mice. In contrast, BMS-536924 treatment increased pAktser473 in muscle. This raises the possibility that the relative lack of metabolic toxicity of BMS-536924 involves varying tissue levels of the drug. These results support the view that host insulin physiology is a potentially modifiable determinant of breast cancer behaviour.

Abstract:
The paper describes a study on reading aloud to a group of four women with mild or moderate dementia living in a nursing home. The purpose of the study was to examine what reactions the reading aloud creates and if the reactions are different if the literature is written in common Swedish or in easy-to-read Swedish. Original and easy-to-read version of the book "The Lady with the Camelias" by Alexandre Dumas was chosen for reading aloud. The study was conducted in two separate parts with four reading sessions in each part. All sessions were filmed with two cameras, one of them focusing the group and the other focusing one individual. Reader was a caregiver at the womens nursing home.The videofilms have been transcribed and the data has been worked up with a qualitative content analysis. The result has thereafter been analysed on the basis of Erving Goffman´s theory of presentation of self together with relevant research. The study shows that the reading aloud awakened many different reactions, especially among the most verbal women. Three out of four women show a greater amount and more varied reactions during the reading ssions with easy-to-read literature. Alas, it is not possible to draw any certain conclusions about the importance of easy-to-read. One reason is the restricted size of group. Another reason is the difference in picture material between the texts which affected the reader´s activity. In spite of these limitations, the study shows that reading aloud can be stimulating for persons with dementia, even in moderate stage. The study also shows that the reader plays an important part in contributing to reactions in the group and especially in the more severely demential women.

Abstract:
Une mesure précise de l’activité physique en conditions de vie libre est nécessaire pour une meilleure compréhension de ses relations avec la santé. Le premier objectif de ce travail thèse a été de valider l’Actiheart (qui combine la mesure de la fréquence cardiaque et du mouvement par accélérométrie) par rapport à l’eau doublement marquée (EDM). Nous montrons un bon niveau de concordance entre la dépense énergétique liée à l’activité physique (DEAP) estimée par l’Actiheart et l’EDM. Une individualisation de la relation entre la fréquence cardiaque et de la DEAP par un test d’effort est nécessaire pour une estimation fiable de la DEAP au niveau individuel et pour évaluer des changements de DEAP tels qu’induits par une intervention. En laboratoire, nous montrons que la précision de l’Actiheart est activité dépendante. Ceci nécessite la mise en place de leur reconnaissance par de nouveaux capteurs et modèles mathématiques. L’adiponectine est une hormone du tissu adipeux qui a un rôle dans le métabolisme énergétique et dont la sécrétion diminue avec l’obésité. Les effets de l’activité physique sont en revanche contradictoires dans la littérature. Le second objectif de ce travail a été d’évaluer l’effet de l’activité physique et d’une intervention avec contrôle du poids sur les taux plasmatiques d’adiponectine. Nous montrons que l’adiponectine totale et à haut poids moléculaire sont associées négativement à la variation du niveau d’activité physique. D’autres travaux sont cependant nécessaires pour comprendre les mécanismes qui sous-tendent cette modulation de l’adiponectine plasmatique qui ne semble pas liée à des variations de synthèse dans le tissu adipeux ou musculaire
Accurate measurements of physical activity in free living are needed to establish what dose of physical activity is necessary for obtaining a specific health benefits. The first aim of this work was to validate the Actiheart (which combines heart rate and accelerometry sensors) with doubly labeled water (DLW). We show a good level of concordance between physical activity energy expenditure (PAEE) estimated by Actiheart and DLW. Individualization of the relationship between heart rate and PAEE by an incremental test is needed for an accurate estimate of the PAEE at the individual level and to evaluate changes induced by an intervention. In laboratory, we show that the accuracy of Actiheart is activitydependent. This requires the establishment of their recognition from new sensors and mathematical models. Adiponectin, hormone secreted by adipose tissue, has a role in energy metabolism and its secretion decreases with obesity. However the effects of physical activity remain in contradiction in published studies. The second objective of this work was to evaluate the effect of physical activity and intervention with weight control on plasma adiponectin. We show that the total and high molecular weight adiponectin were negatively associated with modifications of the physical activity level. Further work is however necessary to understand the mechanisms underlying this modulation of plasma adiponectin which does not seem related to changes in synthesis in adipose tissue or muscle

Fredriksson, Mathias. "Obeskattade reserver : Har en förändring kring användandet och dynamiken mellan periodiseringsfonder och överavskrivningar inträffat?" Thesis, University of Gävle, Department of Business Administration and Economics, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:hig:diva-3818.

Full text
Abstract:

Syfte: År 2005 infördes en ny lag, att företagen som gjorde avsättningar till periodiseringsfonder var tvungna att beskatta en schablonintäkt som erhölls från de gjorda avsättningarna. Problemet som uppsatsen berör är huruvida användandet av överavskrivningar hade förändrats efter att lagen tillkom för periodiseringsfonder jämfört med tidigare. Dessutom fokuserades det också på vilka konsekvenser obeskattade reserver har fått före och efter att lagen trädde i kraft. Syftet med examensarbetet är att kartlägga hur företagens vanor kring avskrivningar över plan förändrades efter införandet av schablonintäkten på periodiseringsfonder, och om överavskrivningar kan anses som ett substitut till periodiseringsfonder istället för ett komplement.

 

Metod: En undersökning gjordes på företagen som är listade på börslistan ”large cap”. De åren som undersökningen omfattade var åren 2003, 2004, 2005 och 2006. Företagen som användes var redan förutbestämda, varför urvalet blev ett subjektivt urval. Anledningen till det var för att undersökningen ämnade skapa en stor insikt i Sveriges ledande börsföretags resultatplanering. De data som insamlades hämtades från företagens årsredovisningar, och data sammanställdes i tabeller och diagram.

 

Resultat & slutsats: Resultatet för undersökningen visade på att företagen hade ett lågt användande av resultatjusteringar redan under år 2003, och det fortsatte att avta allt eftersom åren gick, emellertid fanns en tendens att företagen ökade sitt användande under år 2006.

Periodiseringsfonder var mer vanliga att använda för alla år förutom år 2005. Med detta som underlag blev slutsatsen att överavskrivningar inte är ett substitut till periodiseringsfonder. Vidare tycks företagen inse att det är billigare för dem att inte använda sig av obeskattade reserver, och betala skatten direkt, eftersom färre gjorde avsättningar.

 

Förslag till fortsattforskning: I uppsatsen koncentrerades urvalet till att enbart omfatta Sveriges 60 största börsnoterade företag, och forskningen bör utvidgas till att omfatta ett mer representativt urval i Sveriges företagsklimat. Anledningen till det är för att kunna erhålla en statistisk säkerställning kring användandet av obeskattade reserver.

 

Uppsatsens bidrag: Uppsatsen har skapat en större förståelse kring obeskattade reserver och i vilken omfattning de används bland företagens som tenderar att bestämma praxis. Vidare har också djupare kunskap erhållits kring vilken av de två bokslutsdispositionerna som är mest användbar, samt skatters påverkan på företagens valmöjligheter.


Aim:  By the year 2005 a new law was introduced, the companies was now being charged with an interest income on the tax allocation reserve. The problem this thesis is based on is how the usage of excess depreciation had changed pre and post the new law was established because this tool do not have a fee for its usage. Additionally this thesis also focused on what consequences this law have had on the general usage of untaxed reserves. The purpose with the thesis is to get an understanding if the usage of excess depreciation changed after the tax allocation reserves was being taxed and if excess depreciation can be a substitute to tax allocation reserve instead of being a complement to it.

 

Method: A survey was performed, with the companies listed on the Stockholm stock exchange's large cap as the only objects in the survey. The sample of the survey was pre-decided; hence the sample of the survey was subjective, but also because the survey intended to create an insight in the income planning of the leading enterprises of the stock exchange in Stockholm. The years included in the survey were 2003, 2004, 2005 and 2006 and the data, foundation to the survey, was gathered from the companies' annual reports. 

 

Result & Conclusions: The result of the survey showed that the companies had a low usage of appropriations, already back in 2003, which continued to decrease as the years went by however in the year 2006 a tendency was that the companies had increased their usage of untaxed reserves. Tax allocation reserves were more frequently used in all the years except in the year 2005. With regard to this information following conclusions could be made: excess depreciation could not be seen as a substitute to the tax allocation reserve. Moreover, a decrease in the usage of untaxed reserves could also be seen, as the companies realised that it would be cheaper for them not using them.

 

Suggestions for future research: The survey was narrowed to just include the sixty largest companies traded on the Stockholm exchange; hence the research should be extended to include a more representative sample of all the companies in Sweden. The reason is to find out if the usage in appropriations has changed to the degrees of being statistically significant.

 

Contribution of the thesis: The thesis has produced a greater understanding about appropriations and to what degree the companies who set praxis are using them. Furthermore, a comprehension about which of the two appropriations that is the most useful has been received, and also how much taxes influence the choices made by companies.

Abstract:
La caractérisation des modules cis-régulateurs (CRM) ainsi que de leur activité sont essentiels pour comprendre la régulation des gènes au cours du développement des métazoaires. La technique de l'immunoprécipitation de la chromatine suivie du séquenage à haut débit de l'ADN (ChIP-seq) constitue une approche puissante pour localiser les CRM. Afin de localiser des facteurs génériques au sein de tissus spécifiques, nous avons développé une approche ChIP-seq sur des noyaux triés par cytométrie de flux et localisons des modifications post-traductionelles de l'histone H3, ainsi que l'ARN polymérase II (PolII) dans le mésoderme de la Drosophile. Nous montrons que les CRM actifs sont caractérisés par la présence d'H3 modifiés (K27Ac et K79me3) et de PolII. De plus, la présence et la forme des signaux correspondants à ces marques corrèlent dynamiquement avec l'activité des CRM. Enfin, nous prédisons la présence de CRM actifs et confirmons leur activité in vivo à 89%. Paralllement, nous étudions comment cinq facteurs essentiels au développement cardiaque se coordonnent en cis au sein du mésoderme dorsal, précurseur des mésodermes cardiaque (MC) et viscéral (MV). Nous démontrons que ces facteurs sont recrutés en tant que collectif au niveau des CRM cardiaques via un nombre limité de sites de fixation et en l'absence de contraintes architecturales. En outre, nous découvrons que ces facteurs cardiaques sont recrutés au niveau de CRM actifs dans le MV voisin et activement réprimés dans le MC, reflétant ainsi l'origine tissulaire commune de ces deux populations cellulaires. Nous concluons que les CRM impliqués dans le développement peuvent présenter une empreinte développementale.

Abstract:
Tuberculosis (TB) still remains a health problem globally with over a million new infections and a mortality rate of 1.5 million individuals annually (Hawn et al., 2014). The emerging multi-drug resistant (MDR) strains that accompany human immune deficiency virus (HIV) infection in high-incidence populations contribute significantly to the health burden of TB (Areeshi et al., 2014). The standard treatment that is advocated by the World Health Organization (WHO) for active tuberculosis includes long-term therapy that incorporates the use of isoniazid, rifampicin, pyrazinimide and ethambutol as front line drugs (WHO, 2013). Drug resistance against established treatment options for TB makes research into new forms of therapy an imperative in health care (Ntulela et al., 2009). South Africa is currently witnessing a high number of cases of drug-resistant TB. In some parts of the country, one in ten cases of TB is resistant to treatment. It is therefore essential to have new anti-tuberculosis agents, which can be readily and simply produced from some local source (Warner et al., 2014). A logical starting point for this research of new agents would be the herbal medicines which have been used for centuries in rural areas by local healers. Western developed countries have harvested ethno botanical knowledge and have produced drug therapies for conventional medicines for other ailments. The activity of extracts of the active plants and their properties still require study in animal models in order to assess their future as new anti-tuberculosis agents (Lall and Meyer, 1999). This study focuses on qualitative and quantitative experimental findings after the administration of a medicinal plant extract to animals. This will include daily observation of animals, recording of feed consumption, recording of animal weights, macroscopic examination of animals at necropsy, tissue harvesting, histological procedures and microscopy.
