The vital role played by pictures and diagrams in modern communication is stated with the need for adequate substitutes so that visually impaired people can take full advantage of educational and career opportunities. The multiplicity of purposes to which pictures and diagrams can be put and the diversity of styles which result are discussed. Available methods for producing tactile versions of these (some devised and improved by the author) are described and provisionally evaluated.

The ultimate aim of this empirical study has been to investigate the obstacles visually impaired women in Tanzania face in their struggle for accessing and gaining education. It explores issues of culture, gender, disability, education and development, and examines the ways these interact with one another in shaping the lives of the women under discussion. These issues are conceptualised to establish the theoretical framework of the study. The epistemological and ontological position of the social model of disability has guided the conceptualisation and analysis of the problem under review. Using this model, this study critiques the way in which society perceives disabled people in general, and disabled women in particular. The social model approach emphasises a need to move society's perception of disability away from the medical model approach, which individualises disability. There are two main reasons for my choice of topic for this investigation. Firstly, the research is as much about my own experiences as it is about other visually impaired women. It is argued that the way the identity of visually impaired women is socially constructed, drawing on cultural understandings, social/economic and political barriers and society's negative attitudes towards sex and impairment, has served to inhibit their access to education. Secondly, I decided to research gender disparities in the provision of education for visually impaired persons because it has never previously (to my knowledge) been on research agendas of academics or disability activists in Tanzania. In setting the scene, the thesis starts by justifying the need for researching the problem of inaccessibility of visually impaired women to education in Tanzania. Semi structured interviews were used to generate the primary data for the study. 58 visually impaired women and 26 parents/guardians participated in the research, as well as other 36 key informants. Research findings reveal various obstacles visually impaired women in Tanzania encounter in their struggle for accessing and gaining education. These include cultural, social, economic, political and physicaldifficulties. The findings further highlight outcomes of the educational obstacles on the lives of visually impaired women; reviewing the coping strategies they use in their struggle for survival, and record their views about the ways their education could be improved. The study concludes by suggesting key issues for the way forward. Recommendations directed to all involved in the provision of education for visually impaired women are oriented toward changing attitudes and ensuring that education is their human right and not a matter of charity.

Edwardsiella ictaluri is the causative agent of enteric septicemia of catfish (ESC). Although some virulence mechanisms in E. ictaluri have been identified, further research is needed to discover new virulence genes, which could be used to develop safe and efficacious live vaccines. Here, we report production of growth deficient E. ictaluri mutants on complex agar media and identification of genes causing this growth deficiency. The overall goal of this project is to generate growth deficient E. ictaluri mutants and identify genes causing this growth deficiency on complex media. Mutants exhibiting slow growth in complex media may be potential candidates for vaccine development. In this study, 56 unique E. ictaluri genes have been identified. 32 of them showed host protein binding properties while 30 of them were found to be involved in bacterial virulence in other pathogenic bacteria.

Despite modest reductions over previous decades, improvements in impaired driving prevalence have stalled at problematic levels in recent years. Recent self-report data indicate that 20 percent of driving age individuals acknowledge operating a vehicle within two hours of alcohol consumption within the previous year and there are approximately 121 million episodes of impaired driving annually. Extant research has consistently identified specific subgroups, including men, young adults, and individuals with less education, as being high risk for driving under the influence. Additionally, researchers of impaired driving have discerned certain impaired driving-related attitudes and behaviors as important predictors of impaired driving. Despite a large and growing base of literature, impaired driving research has been notably atheoretical and restricted by samples limited to specific ages or geographic regions. Regardless of the prevalence of impaired driving episodes, the likelihood of apprehension for DUI remains low and little is known about how offenders respond to an impaired driving arrest. I address these limitations in the current study. Using nationally representative data from the National Survey of Drinking and Driving Attitudes and Behaviors, I consider the role of cognitive and behavioral predictors as mediating the association between key socio-structural indicators and impaired driving. To consider how individuals respond to DUI arrests, I performed an extensive qualitative content analysis on 627 DUI narratives from reddit (i.e., an online social forum) to consider how the arrest affects individuals apprehended for driving under the influence. Path analyses provide further support for previous studies, with men and young adults more likely to self-report impaired driving compared to females and older reference groups. Further, analyses indicate this increased likelihood of impaired driving by men and young adults was explained in part by differences in monthly alcohol consumption, binge drinking, supportive social networks, and more positive assessments of impaired driving. Analyses of DUI offenders indicate a stigmatizing effect of the DUI arrest, where offenders strategically attempt to deflect culpability for their role in attempts to minimize the range of perceived negative consequences. Overall, theoretical considerations and findings provide additional insight and areas of exploration for researchers and practitioners tasked with DUI mitigation efforts.
