African Language Publishing For Children In South Africa: Challenges For Translators, Viv Edwards, Jacob Marriote Ngwaru Jan 2011

African Language Publishing For Children In South Africa: Challenges For Translators, Viv Edwards, Jacob Marriote Ngwaru

Institute for Educational Development, East Africa

The commitment to multilingualism embedded in the 1996 South African Constitution has wide ranging implications for many aspects of education. This paper focuses on the dearth of teaching and learning materials in African languages required to deliver effective bilingual education, and on the potential role of translation in offering solutions for this problem. Drawing on an analysis of currently available African language books for children and interviews with educators, writers, publishers, translators and organisations concerned with book promotion, it explores issues which have emerged as critical for both the quality and availability of translation. Attention is drawn to the ways …


American Manpower: Work And Masculinity In The 1970s, Victoria Ludas Jan 2011

American Manpower: Work And Masculinity In The 1970s, Victoria Ludas

All Open Access Legacy Dissertations and Capstone Projects

This paper is about three things, as examined over the course of the 1970s: the changes in the state and dependability of work, the pressures of masculinity as felt by heterosexual white men over the age of 20 in the working and middle classes, and what occurred because of the relationship between work and that masculinity. To understand 3 the third, it is necessary to understand the first two, and what happened in both cases during the decade. Even disregarding the male-female dynamic in the increase in women at work, the state of employment changed in massive and permanent ways. …

Development Of A Nanoparticulate Drug Delivery Vehicle For Retinoic Acid, Noah Capurso Jan 2011

Development Of A Nanoparticulate Drug Delivery Vehicle For Retinoic Acid, Noah Capurso

Yale Medicine Thesis Digital Library

Retinoic acid (RA) is a small molecule capable of shunting developing T cells away from the Th17 lineage and towards the Treg phenotype, making it a potentially useful therapeutic for autoimmune and inflammatory diseases. However, therapy can be complicated by systemic toxicity and unpredictable bioavailability, making a targeted drug delivery vehicle for local therapy desirable. A promising approach is the use of nanoparticles, which have been demonstrated to increase potency and decrease toxicity of therapies in a variety of disease models including Th17 mediated diseases. We therefore constructed a nanoparticulate drug delivery platform from poly(lactic-co-glycolic acid) (PLGA) capable of encapsulating …


Development Of A Viral Vaccine Vector Expressing A P. Falciparum Erythrocyte Membrane Protein Domain To Target Severe Malaria, Sara Eve Crager Jan 2011

Development Of A Viral Vaccine Vector Expressing A P. Falciparum Erythrocyte Membrane Protein Domain To Target Severe Malaria, Sara Eve Crager

Yale Medicine Thesis Digital Library

There are an estimated 300-500 million cases of malaria every year, resulting in approximately 2 million deaths. Malaria mortality occurs primarily in children under the age of five, and is resultant from the development of severe malaria. Attempts to control P. falciparum malaria face rapidly escalating levels of resistance on two fronts: the parasite to anti-malarial drugs, and the mosquito vector to insecticides. Despite current prevention efforts, the global incidence of malaria continues to rise and there is a clear and urgent need for a malaria vaccine. Malaria vaccine efforts thus far have been largely unsuccessful in eliciting robust and …


Contextual Influences On Peer Acceptance And The Social Behavior Of Individuals With Intellectual Disabilities, Caroline Brooke Green Jan 2011

Contextual Influences On Peer Acceptance And The Social Behavior Of Individuals With Intellectual Disabilities, Caroline Brooke Green

Electronic Theses and Dissertations

Much attention has been paid to the social behavior of individuals with Intellectual Disability (IDs) due in part to its relevance to quality of life. Deficiencies in social skills are comamong persons with IDs and may include problem behaviors such as withdrawal, aggression, and difficulty communicating with others and social skills training programs have been developed to improve social functioning. However, these programs have generally assumed that the social behavior of persons with IDs should be the same as that of individuals without IDs, yet, relatively little is known about the nature of the relationships among individuals with IDs and …


Characterization Of Cis-Regulatory Elements Controlling Repo Transcription In Drosophila Melanogaster, Robert Johnson Jan 2011

Characterization Of Cis-Regulatory Elements Controlling Repo Transcription In Drosophila Melanogaster, Robert Johnson

Electronic Theses and Dissertations

The glial cells missing (gcm) gene has been identified as a "master regulator" of glial cell fate in the fruit fly Drosophila . However, the gcm gene is also expressed in and required for the development of larval macrophages and tendon cells, and lamina neurons in the adult CNS. Thus, the Gcm protein activates the transcription of different sets of genes in different developmental contexts. How the Gcm protein regulates these different outcomes is not known. My long-term goal is to identify proteins that collaborate with Gcm to promote the transcriptional activation of Gcm target genes specifically in glial cells, …


Design, Synthesis, Biological Evaluation And Metabolic Stability Studies Of Sigma Receptor Ligands, Rohit Bhat Jan 2011

Design, Synthesis, Biological Evaluation And Metabolic Stability Studies Of Sigma Receptor Ligands, Rohit Bhat

Electronic Theses and Dissertations

Sigma receptors represent a unique family of proteins that includes two subtypes: sigma-1 and sigma-2. Sigma-1 receptors have been implicated in the behavioral and motivational effects of psychostimulants as well as in the pathophysiology of depression and Alzheimer's disease. Sigma-2 receptors are widely expressed on many tumor cells and they are believed to play an important role in tumor cell proliferation. Therefore, sigma receptors are attractive targets for developing pharmaceutical agents directed to the treatment of psychostimulant abuse, cancer, Alzheimer's disease as well as diagnostic agents for cancer and brain imaging. A derivatized 2(3H)-benzothiazolone, (3-(2-(azepan-1-yl)ethyl)-6-propylbenzo[ d]thiazol-2(3H)-one) was reported to have …

Application Of A Novel Boronated Porphyrin (H2Ocp) As A Dual Sensitizer For Both Pdt And Bnct, Ryo Hiramatsu, Shinji Kawabata, Shin Ichi Miyatake, Toshihiko Kuroiwa, Michael W. Easson, M. Graça H. Vicente

Faculty Publications

Background: and Objective Boronated porphyrins have emerged as promising dual sensitizers for use in both photodynamic therapy (PDT) and boron neutron capture therapy (BNCT), by virtue of their known tumor affinity, low cytotoxicity in dark conditions, and easy synthesis with high boron content. Octa-anionic 5,10,15,20-tetra[3,5-(nido-carboranylmethyl)phenyl] porphyrin (H2OCP) is a boronated porphyrin having eight boron clusters linked to the porphyrin ring. To evaluate H2OCP's applicability to both PDT and BNCT, we performed an in vitro and ex vivo study using F98 rat glioma cells. Materials and Methods We examined the time-dependent cellular uptake of H 2OCP by measuring the boron concentration …

Virus-Derived Sirnas And Pirnas In Immunity And Pathogenesis, Shou Wei Ding, Rui Lu Jan 2011

Virus-Derived Sirnas And Pirnas In Immunity And Pathogenesis, Shou Wei Ding, Rui Lu

Faculty Publications

Cellular organisms have evolved related pathways for the biogenesis and function of small interfering RNAs (siRNAs), microRNAs and PIWI-interacting RNAs (piRNAs). These distinct classes of small RNAs guide specific gene silencing at both transcriptional and posttranscriptional levels by serving as specificity determinants. Small RNAs of virus and host origins have been found to modulate virus-host interactions by RNA interference (RNAi), leading to antiviral immunity or viral pathogenesis. Deep sequencing-based profiling of virus-derived small RNAs as products of host immune recognition not only allowed us to gain insight into the expansion and functional specialization of host factors involved in the antiviral …

Automated Scanning Probe Lithography With N-Alkanethiol Self-Assembled Monolayers On Au(111): Application For Teaching Undergraduate Laboratories, Treva T. Brown, Zorabel M. Lejeune, Kai Liu, Sean Hardin, Jie Ren Li, Kresimir Rupnik, Jayne C. Garno

Faculty Publications

Controllers for scanning probe instruments can be programmed for automated lithography to generate desired surface arrangements of nanopatterns of organic thin films, such as n-alkanethiol self-assembled monolayers (SAMs). In this report, atomic force microscopy (AFM) methods of lithography known as nanoshaving and nano-grafting are used to write nanopatterns within organic thin films. Commercial instruments provide software to control the length, direction, speed, and applied force of the scanning motion of the tip. For nanoshaving, higher forces are applied to an AFM tip to selectively remove regions of the matrix monolayer, exposing bare areas of the gold substrate. Nanografting is accomplished …


Oncogenic Potential Of Yin Yang 1 Mediated Through Control Of Imprinted Genes, Michelle M. Thiaville, Joomyeong Kim Jan 2011

Oncogenic Potential Of Yin Yang 1 Mediated Through Control Of Imprinted Genes, Michelle M. Thiaville, Joomyeong Kim

Faculty Publications

The transcription factor Yin Yang (YY) 1 is one of the most evolutionarily well-conserved DNA binding proteins that is ubiquitously expressed among different tissue types. YY1 functions as a critical regulator for a diverse set of genes, making its role in the cancerous environment elusive. Recent studies have demonstrated that clusters of YY1 binding sites are overrepresented in imprinted gene loci. These clustered binding sites may function as a molecular rheostat with respect to YY1 protein levels. YY1 levels were documented to be altered in various tumor tissues in conjunction with the transcriptional levels of the imprinted genes it regulates. …

The Large Decapitating Fly Pseudacteon Litoralis (Diptera: Phoridae): Successfully Established On Fire Ant Populations In Alabama, Sanford D. Porter, L. C. Graham, Seth J. Johnson, Larry G. Thead, Juan A. Briano

Faculty Publications

The large fire ant decapitating fly, Pseudacteon litoralis Borgmeier, from northeastern Argentina was successfully released as a self-sustaining biocontrol agent of imported fire ants in south central Alabama in 2005. Five years later, this fly is firmly established at the original release site and has expanded outward at least 18 km. Nevertheless, populations remain very low considering P. litoralis is one of the most abundant fire ant decapitating flies in large areas of its range in South America. The reasons for low densities and why we were only able to establish this fly at 1 of 9 release sites in …

Faculty Publications

Background A preliminary genome-wide linkage analysis of blood pressure in the Family Blood Pressure Program (FBPP) was reported previously. We harnessed the power and ethnic diversity of the final pooled FBPP dataset to identify novel loci for blood pressure thereby enhancing localization of genes containing less common variants with large effects on blood pressure levels and hypertension.MethodsWe performed one overall and 4 race-specific meta-analyses of genome-wide blood pressure linkage scans using data on 4,226 African-American, 2,154 Asian, 4,229 Caucasian, and 2,435 Mexican-American participants (total N = 13,044). Variance components models were fit to measured (raw) blood pressure levels and two …


Reverse Causation And Illness-Related Weight Loss In Observational Studies Of Body Weight And Mortality, Katherine M. Flegal, Barry I. Graubard, David F. Williamson, Richard S. Cooper Jan 2011

Reverse Causation And Illness-Related Weight Loss In Observational Studies Of Body Weight And Mortality, Katherine M. Flegal, Barry I. Graubard, David F. Williamson, Richard S. Cooper

Faculty Publications

In studies of weight and mortality, the construct of reverse causation has come to be used to imply that the exposure-outcome relation is biased by weight loss due to preexisting illness. Observed weight-mortality associations are sometimes thought to result from this bias. Evidence for the occurrence of such bias is weak and inconsistent, suggesting that either the analytical methods used have been inadequate or else illness-related weight loss is not an important source of bias. Deleting participants has been the most frequent approach to control possible bias. As implemented, this can lead to deletion of almost 90% of all deaths …

Clark, Daniel Strickman

Faculty Publications

The goal of this study was to evaluate the effectiveness of a public health educational campaign to reduce backyard mosquito-larval habitats. Three communities each, within two New Jersey counties, were randomly selected to receive: (1) both education and mosquito control, (2) education only, and (3) no education or mosquito control. Four separate educational events included a 5-day elementary school curriculum in the spring, and three door to door distributions of educational brochures. Before and after each educational event, the numbers of mosquito-larval container habitats were counted in 50 randomly selected homes per study area. Container surveys allowed us to measure …

“Describing Our Whole Experience”: The Statistical Philosophies Of W.F.R. Weldon And Karl Pearson, Charles H. Pence Jan 2011

“Describing Our Whole Experience”: The Statistical Philosophies Of W.F.R. Weldon And Karl Pearson, Charles H. Pence

Faculty Publications

There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a reading of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach …


Nietzsche’S Aesthetic Critique Of Darwin, Charles H. Pence Jan 2011

Nietzsche’S Aesthetic Critique Of Darwin, Charles H. Pence

Faculty Publications

Despite his position as one of the first philosophers to write in the “post- Darwinian” world, the critique of Darwin by Friedrich Nietzsche is often ignored for a host of unsatisfactory reasons. I argue that Nietzsche’s critique of Darwin is important to the study of both Nietzsche’s and Darwin’s impact on philosophy. Further, I show that the central claims of Nietzsche’s critique have been broadly misunderstood. I then present a new reading of Nietzsche’s core criticism of Darwin. An important part of Nietzsche’s response can best be understood as an aesthetic critique of Darwin, reacting to what he saw as …
