The purpose of this research is to examine the longevity of the stereotype of the tragic mulatto in American film history. Specifically, my research focuses on the portrayals and perceptions of biracial actresses. Media informs, entertains, and influences how we, and especially youth, self-identify and interact with others. This research focuses on the portrayal of biracial actresses throughout film history. It is also important in its investigation of the perpetuation of the one-drop rule. In this research, I will examine if historical stereotypes of tragic mulatto are apparent in contemporary Hollywood film. The methodologies used in this research include a content analysis of films with biracial actresses and an online survey of respondents’ perceptions of four actresses. Statistical techniques used for analysis include ordinary least square regression and multinomial logistic regression. Findings suggest that the tragic mulatto stereotype is not blatant in contemporary Hollywood film, but issues of colorism may be apparent.

In this thesis, we discuss a new kind of polygon, which we call one-sided polygons. The shortest path between any pair of vertices of a one-sided polygon makes only left turns or right turns. We prove that the set of one-sided polygons is a superset of the star-shaped polygons and the spiral polygons. We also show that the set of one-sided polygons is a subset of the set of LR-visibility polygons. We present a linear time recognition algorithm for one-sided rectilinear polygons. We then discuss the searching of monotone and one-sided rectilinear polygons. We show that all one-sided polygons can be 1-searched and a search schedule can be given in linear time.

The main principle behind the working of delay tolerant networks (DTN) is the mobility of the nodes along with their contact sequences for exchanging data. Nodes which are a part of the DTN network can behave selfishly due to network reservation policy, especially when constrained to energy or storage space. Several forwarding protocols exist for spreading data but our focus is on the performance of popular data relaying protocols namely epidemic routing and two hop routing protocol in a situation where nodes exhibit various degrees of selfishness. Results of an analytical model show the performance advantage of epidemic routing over two hop routing decreases as the number of selfish nodes and intensity of the selfishness increases either deterministically or probabilistically. We practically asses the vulnerability of the above mentioned protocols using ONE simulator. We find that our result coincides with analytical results with some variations in the graph.

Abstract The fertility rate of Taiwan has been decreased year by year,a ministry of the interior announced the number of new born baby which was a record low below 200 thousand;a ministry of education proposed the bill of integrating kindergartens and nuesery schools to the legislative yuan for the first reading,it will be legally public school to recruit kids who from 0~6 years old,at the same time,the requisitions of operating threshold to private kindergarten owners has raised,otherwise the subsidies for tuition will be rescind;the government established policy of downward extension of one year compulsory education,but the big class(5~6) kids are the largest proportion for most of private kindergartens;individual counties to implement the nation primary free after school,others will follow a succession like this.

During the game of squash, the transfer of thermal energy to the squash ball is integral to increase the bounce height of the ball. This investigation involves the transfer of thermal energy to squash balls of the same brand and specification to observe the effect on hang time. Preliminary work involved determining the specific heat capacity of the squash balls. On completing the investigation, the results showed a linear relationship between the thermal energy applied and the hang time.

In Canada, parasitism in people and well-managed animal populations is less common now than a century ago, likely due to accessible anthelmintics, heightened public awareness, and improved sanitation. Some zoonotic parasites, such as Echinococcus canadensis are now rarely diagnosed in people, but persist mainly in northern populations where diagnostic services are limited. Veterinary services are also limited in these areas, and as a result, human and animal incidence data does not exist, is outdated, or underestimates the true incidence. We closed this knowledge gap in certain areas of western Canada by determining the prevalence of E. canadensis and other zoonotic parasites in wildlife (wolves [Canis lupus] and ungulates; Chapters 2 and 3), domestic dogs (Canis familiaris; Chapters 4 and 5), and people (Chapters 6-8). Using a One Health framework, we also explored parasite control practices and potential policy solutions for rural and remote communities (Chapters 8 and 9). During post-mortem examination, we observed E. canadensis in approximately 11% (11/105) of elk [Cervus canadensis], and 21% (34/165) of wolves. Our examination of historical post-mortem reports of ungulates demonstrated that E. canadensis is distributed throughout Canada, except for the high Arctic islands, the Maritime provinces, and the island of Newfoundland. Our analysis of dog feces collected throughout Saskatchewan suggested that patent taeniid (Taenia or Echinococcus spp.) infection was rare (0-4%), and that rural and northern dogs had higher endoparasitism than urban dogs. Sero-surveillance for four zoonoses (E. canadensis, Toxoplasma gondii, Trichinella, and Toxocara canis) by enzyme-linked immunosorbent assay indicated similar results - that people in northern SK (65% of 201) had higher exposure to one or more parasites than those in southern SK (12% of 113). Using patient health records, we reported annual incidence rates for clinical illness for the following zoonotic parasites: echinococcosis – 1.4/1 000 000; toxoplasmosis- 1.7/1 000 000; and toxocariasis-0.06/1 000 000. In the final chapter we compared the cost of treating human echinococcosis cases with a prevention program based on dosing dogs with praziquantel at 6 week intervals in the Kelsey Trail region, where human incidence is highest. Based on direct healthcare costs, such a program is not currently cost saving, but could become so if echinococcosis incidence increased. Preventative programs should be considered for high risk communities, which are often economically marginalized and lack appropriate resources to effectively control zoonotic parasitism. Putting One Health into action may require integrated human-animal healthcare services, introduction of community-based animal health workers, and increased transdisciplinary research to improve access to and uptake of preventative healthcare services for parasitic zoonoses in northern and remote communities.

Xbox One är en spelkonsol från företaget Microsoft och en uppföljare till Xbox 360. Konsolen presenterades officiellt vid en presskonferens den 21 maj 2013 och före presentationen så fanns det ett av många rykten om ett krav på att vara ständigt uppkopplad mot internet som rapporterades i media. Syftet med uppsatsen har varit att i utifrån efterförloppet av Microsofts premiärlansering av spelkonsolen Xbox One undersöka den diskursiva bild som nyhetsmedierna Forbes och Time använder för att skildra och rama in Xbox One under den första månaden efter produktens lansering. Vår frågeställning har varit: – Hur framställer Time och Forbes information om Xbox One, och ramar in detta under tidsperioden 21 maj – 21 juni 2013? Denna uppsats har utgått från teori om mediekonvergens som beskriver att konvergens förändrar relationen mellan existerande teknologier, industrier, marknader och publiker. För att nå ett resultat så har en diskursiv analys gjorts i nämnda nyhetsmedier utifrån Teun A. van Dijk och hans makro- och mikroperspektiv på en strukturell nivå inom den kritiska diskursanalysen.I resultatet framkom sju stycken huvudteman som vi valt att kalla mediesystem, DRM, övervakning/privacy, Xbox One som marknadsföringsverktyg, ekonomi, PR och policyförändring. Studiens resultat pekar i en riktning där begrepp som ägandeskap, övervakning, digitalisering av upphovsrättsligt material, konvergens, makt och kultur som en kommersiell vara existerar, och berör områden inom medie- och kommunikationsvetenskap där en digital konvergens skett som gjort spelkonsoler till ett multimedialt medium. I en överblick över samtliga artiklar analyserade utifrån ett framingperspektiv, och utifrån problemdefinitionen, så framkommer det att de två största inramade problemen är kring kommunikation och internet och de övergripande moraliska utvärderingarna under temat internet är att konsumenterna drabbas negativt av Microsofts policy kring Xbox Ones uppkopplingskrav mot internet.
