Syftet med denna uppsats är att undersöka hur förhållandet mellan genus och sexualitet uttrycks i romantiska kärleksfilmer. Ur filmen 500 days of Summer har jag valt att analysera vissa scener där uttryck för en binär genusuppdelning och en normativ sexualitet förekommer, främst skildrat genom romantiska föreställningar om heterosexuell kärlek. Samtidigt har jag också funnit och valt material från filmen som visar på nästintill motsatsen till heteronormativitet och som kan ge förhoppningar om nya ideal inom den romantiska kärleksfilmen. 500 days of Summer är en väldigt ambivalent film, parallellt problematisk och nyskapande då den sitt bruk av filmgrepp både befäster men också bereder väg för nya tolkningar av genus och sexualitet. Följande uppsats är en undersökning i hur iscensättning av normativa ideal fungerar och tar sig uttryck i filmmediet och vilka begränsningar samt möjligheter detta erbjuder.

This study examines George Orwell's contribution to our understanding of imperialism and to political writing in general. The basic assumptions of the study are that for a creative writer plot performs essentially the same function as model-building does for the political scientist and the role of the imagination is paramount both in the drawing of a novelist's picture of environment and in a social scientist's selection of variables. To show how a creative writer can offer the student of politics an unusual perspective of various systems of government (in this case, imperialism), the study draws upon concrete examples from Orwell's novel Burmese Days and other of his related writings to illustrate a number of political science's theoretical concepts. The study is also concerned with showing how Orwell was a pacesetter, as it were, in rejecting jargon as a means of expression and instead pressing vigorously, particularly in his description of imperialism in Burmese Days, for a straightforward yet imaginative prose in describing political as well as other events. The study assumes that Orwell's plea is echoed in a succeeding generation by others such as Landau and asserts that Burmese Days has either rendered many of imperialism's more harmful clichés impotent or has at least exposed them to closer scrutiny. At the same time, despite Orwell's often vehement denunciation of imperialism, it is assumed that there is implicit in the dialogue of some of his characters a recognition that while the system of uninvited foreigners exploiting and governing another people's country may be morally repugnant, in the light of an all-embracing and privacy-invading industrialism British imperialism may have been the least offensive kind of such exploitation. The study argues that our understanding of the motivations for group behaviour may, in some cases such as imperialism, be best pursued through more intensive studies of individuals within the group rather than by investing all of our attention in observing the collective action of the group. The study has evolved not from the notion that a creative writer can ever replace the perhaps more disciplined approach of the social sciences in understanding our world, but that he can significantly aid the academic world in illustrating its theoretical concepts. Finally, it is the overriding conclusion of this study that the moderately experimental nature of its juxtaposition of social science theory and fiction is mutually beneficial to both the social scientist and the student of literature in offering them new perspectives in their respective fields of interest. / Arts, Faculty of / Political Science, Department of / Graduate

Adoption of glyphosate-resistant crops has resulted in increased glyphosate usage and decreased use of residual herbicides thus resulting in weed pressure shifts. Weeds that display multiple-resistance to glyphosate and other herbicide modes of action have become a concern in many parts of the United States. Incorporation of multiple herbicide resistance traits into multiple cropping systems, may facilitate weed resistance to additional herbicides. Furthermore, controlling volunteer crop stands containing multiple herbicide-resistance traits may be problematic in herbicide resistant crops. These volunteer crops will compete with the currently growing crop qualifying them as a weed. Therefore, this research was conducted to determine control options for: failed glyphosate resistant corn stands, and volunteer glyphosate resistant corn stands in glyphosate resistant cotton. Furthermore, research was conducted to determine what densities of glyphosate-resistant corn will cause cotton yield loss and if time of removal of these densities impacts cotton yield loss.

Studies were conducted on the effects of alcohol and opioids on the development of forensically important flies. In addition different methods of degree-day calculations and development thresholds were used to determine the effects on PMI estimates. The first study determined the effects of ethanol on the development of Phormia regina in vitro. Ground pork loin was treated with a 1, 5, or 10% ethanol solution to give an equivalent Blood Alcohol Concentration (BAC) of 0.01, 0.04, and 0.8 % w/v. A significant difference in the time for second instars to complete the stage was seen between the 1% treated and control. Significant differences were also found among pupal and adult weights between all treatments and the control. A significant difference was shown between growth curves of the 5% treated and control for third instar larvae using the Kolmogorov-Smirnov test. The ethanol content of Phormia regina in migrating third instar larvae that fed on treated meat was examined using headspace-gas chromatography (HSGC). All larvae had a content of 0.01% w/v, including the control. The effects of ante-mortem injection of oxycodone in pigs were examined with respect to insect succession patterns and the development rates of Phormia regina. Pigs were given a subcutaneous injection of oxycodone hydrochloride (3 mg/kg by weight) and antemortem blood samples were collected prior to and following drug injection. Shortly after death the carcasses were placed at an open field site and allowed to decompose in a field cage. Insect samples were collected from carcasses for seven days post-mortem and the collected data were used to develop occurrence matrices. The Simple Matching Coefficient showed that successional patterns were similar between treated and untreated animals. Loin and liver from the carcasses were used as rearing media for in vitro development studies of Phormia regina. Kolmogorov-Smirnov test showed that third instar P. regina maggots from treated loin tissue were significantly longer in length than maggots feeding on untreated loin tissue. A significant difference in time was found among larvae on loin for the time from eclosion to completion of the second instar. Significant differences were seen in the weight of adults reared on liver and loin. A chi-square for homogeneity showed that adults were biased towards males (2:1) from untreated loin tissue. A final study compared weather data sources, Accumulated Degree-Day (ADD) methods, and postmortem interval (PMI) estimations based on threshold and developmental data source. Four pigs were used for statistical comparisons. Pigs were taken to a test site and allowed to decompose in an experimental cage. Probes recorded ambient temperatures and body temperatures. Maggot sampling was completed every day for each pig. A three way factorial linear fit model was used to test for statistical differences. Significant differences were seen in the calculated ADD based on probe location and the development threshold used. The ADD calculated from local weather station locations: Kentland Farm, Moore Farm, and Blacksburg Airport were also compared. A significant difference in ADD was found in the main effects among locations (Airport 44.1 ADD, Kentland 37.5 ADD, Moore 48.6 ADD), as well as among the thresholds used (10,12.2, and 14°C). Different PMI estimations also resulted when using development data from different development studies on Phormia regina. / Ph. D.

The purpose of this study is to examine rural children's sedentary time during school days vs non-school days Currently, childhood obesity research has focused predominantly on urban-dwelling children. However, existing literature indicates that rural children have higher rates of obesity than their urban counterparts. There is a current lack of evidence investigating the obesogenic behaviors of rural children, such as physical activity levels, sleep duration, sedentary behaviors and diet. With this project, I aim to observe sedentary time (time spent sitting, screen time etc.) as research has shown that independent of physical activity, sedentary time is associated with weight gain. A secondary aim of this research is to test the Structured Days Hypothesis which states that children engage in less-favorable obesogenic behaviors (e.g., prolonged sitting, higher screen time) during non-school versus school-days due to the removal of ‘structure' during non-school days.

This thesis examines the relationship between working capital efficiency and firm profitability, and how this relationship is affected by economic fluctuations. In the existing literature, the relationship between working capital efficiency and firm profitability has been extensively researched. However, the impact of economic fluctuations on the relationship between working capital efficiency and firm profitability is sparsely researched. To the best of our knowledge, only Enqvist, Graham and Nikkinen (2014) have addressed the impact ofeconomic fluctuations on the relationship between working capital efficiency and firm profitability. This thesis is a replication of their study in another geographical setting, another time period and studying different types of firms. Using a sample of 2,589 firm-year observations of listed Swedish firms for the years 2000-2015, this thesis conducts multiple regression analysis to examine the relationship between working capital efficiency and firm profitability. The findings of this thesis propose that firms can enhance profitability by improving their working capital efficiency. However, the relationship between working capital efficiency and firm profitability does not appear to be significantly affected by economic fluctuations. This thesis contributes to the existing literature by further strengthening the understanding of the relationship between working capital efficiency and firm profitability. In addition, it also adds to the existing literature on the relationship between working capital efficiency and firm profitability in a Swedish context.

Busseola fusca is an indigenous lepidopteran pest species in tropical Africa, attacking several grain crops. Crop loss caused by this pest can be as high as 100 % depending on conditions. Despite it being a major pest in Africa, occurring in contrasting climatic zones, only a few studies have been published on its developmental biology. The effect of temperature on the development of B. fusca was studied at five different temperature regimes namely 15, 18, 20, 26 and 30 ± 1 °C and 70 ± 30 % relative humidity (RH) with 14L: 10D photoperiod. The number of instars for B. fusca was also determined. The most favourable temperature as well as the upper threshold temperature for larval development was found to be between 26 and 30 °C. Total development period was 152.6 to 52.6 days, respectively, at 15 °C, and 26 - 30 °C. The thermal constants for B. fusca was 99.50, 536.48, 246.25 and 893.66 °D and lower temperature threshold was 10.36, 8.14, 8.99 and 8.84 °C, for completion of the egg, larval, pupal, and egg-to-adult stages, respectively. The number of larval instars was determined by using head capsule widths that ranged from 0.31 - 2.68 mm. Clear distinctions of head capsule widths could be made from instar 1 to 3, yet overlapping occurred from instar 4 to 6. No distinction could be made between instars 7 and 8 in terms of head capsule width. All successive instars, except for instar eight, increased in size according to Dyar’s ratio. The effect of temperature on reproduction of B. fusca was studied at 15, 20, 26 and 30 ± 1 °C, 70 ± 30 % RH with 14L: 10D photoperiod. Oviposition occurred at all the temperatures evaluated, but no fertility was recorded at 30 °C. The total number of eggs laid by B. fusca females was 300 - 400 eggs and the optimum temperature for oviposition and fertility was determined to be between 20 and 26 °C. Results from this study on the thermal constants and lower and upper threshold temperatures of B. fusca can be used to predict the impact of climate change on the distribution and population growth of this pest. / MSc (Environmental Sciences), North-West University, Potchefstroom Campus, 2015
