Evidence of Natural Bluetongue Virus Infection among African Carnivores
Bluetongue is an International Office of Epizootics List A disease described as the century\u27s most economically devastating affliction of sheep. Bluetongue (BLU) viruses were thought to infect only ruminants, shrews, and some rodents, but recently, inadvertent administration of BLU virus-contaminated vaccine resulted in mortality and abortion among domestic dogs. We present evidence of natural BLU virus infection among African carnivores that dramatically widens the spectrum of susceptible hosts. We hypothesize that such infection occurred after ingestion of meat and organs from BLU virus infected prey species. The effect of BLU virus on endangered carnivores such as the cheetah and African wild dog requires urgent investigation. Also, the role of carnivores in the epizootiology of this disease needs elucidation
Neutralizing antibodies and pathogenesis of hepatitis C virus infection.
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease worldwide. The interplay between the virus and host innate and adaptive immune responses determines the outcome of infection. There is increasing evidence that host neutralizing responses play a relevant role in the resulting pathogenesis. Furthermore, viral evasion from host neutralizing antibodies has been revealed to be an important contributor in leading both to viral persistence in acute liver graft infection following liver transplantation, and to chronic viral infection. The development of novel model systems to study HCV entry and neutralization has allowed a detailed understanding of the molecular mechanisms of virus-host interactions during antibody-mediated neutralization. The understanding of these mechanisms will ultimately contribute to the development of novel antiviral preventive strategies for liver graft infection and an urgently needed vaccine. This review summarizes recent concepts of the role of neutralizing antibodies in viral clearance and protection, and highlights consequences of viral escape from neutralizing antibodies in the pathogenesis of HCV infection
Storytelling and Networking on Tibet: Relationships between narratives, framing and networks within and between two oppositional issue networks
Thesis (Ph.D.)--University of Washington, 2014This study is centered on issues of storytelling, persuasion, and politics on websites: how stories are made accessible on the web and how these stories are asserted as truths. This study analyzes these issues through researching shared and contested online narratives in two competing issue networks concerning Tibet, Tibetan refugees and the Tibet Movement: an issue network in support of the Tibet Movement and an issue network based in the People's Republic of China (PRC) that generates English language propaganda in support of the Chinese Communist Party's (CCP) policies regarding the Tibet Autonomous Region (TAR) and Tibetan refugee relations. This dissertation project combines hyperlink network analysis (HNA) and website narrative analysis to analyze these two issue networks and the relationship between each issue network's narratives, framing strategies, network characteristics and linking practices. The results of this study will shed light on how narratives and frames are shared, contested and countered across and between issue networks and how narrative practices of persuasion are used to establish hyperlink network ties that construct web networks with specific political functions
Shifting logics of constructability and design : a study of emerging AEC integrated practices for enegry performance
In this paper, we analyze the practices of translation and synthesis for energy performance in building design. We use grounded theory method to collect and analyze qualitative interview and observation data to examine the difficulties of knowledge sharing and problem solving between builders and architectural and engineering designers. Extending the theory of disciplinary specific “institutional logics,” we show that designers and builders integrate their work in three ways: 1) by addressing gaps in their own knowledge that require information from a knowledge domain different from their own, 2) by synthesizing design and construction issues holistically, and 3) through integrating construction and design work practices. These insights offer evidence of shifts in the institutional logics that structure the construction and design disciplines.Non UBCUnreviewedFacultyOthe

The Role of Gender in Violence Experienced by Adults With Developmental Disabilities
Violence against people with developmental disabilities is a highly prevalent yet understudied phenomenon. In particular, there is a paucity of literature surrounding the role of gender and the experiences of men. Using a cross-sectional study design, we surveyed 350 people with diverse developmental disabilities about experiences of abuse, perpetrators of abuse, and their physical and mental health status. These data were analyzed to determine whether gender influenced these domains. Statistical methods included chi-square, independent t tests, logistic regression, and hierarchical multiple regressions. Male and female participants reported abuse at high rates, with 61.9% of men and 58.2% of women reporting abuse as children and 63.7% of men and 68.2% of women reporting abuse as adults. More women than men reported adult sexual abuse, but there was no gender difference in the prevalence of any other form of abuse. Women were more likely than men to identify an intimate partner as their abuser, although intimate partners represented the minority of abusers for both men and women. Violence was associated with worse health status regardless of participant gender. These findings confirm that violence is an important issue for both men and women with developmental disabilities. Although some expected gender differences arose, such as higher rates of adult sexual abuse and intimate partner violence against women, these differences were less pronounced than they are in the general population, and the overall picture of abuse was one of gender similarities rather than differences
