Southern Promise and Necessity: Texas, Regional Identity, and the National Woman Suffrage Movement, 1868-1920
This study offers a concentrated view of how a national movement developed networks from the grassroots up and how regional identity can influence national campaign strategies by examining the roles Texas and Texans played in the woman suffrage movement in the United States. The interest that multiple generations of national woman suffrage leaders showed in Texas, from Reconstruction through the ratification of the Nineteenth Amendment, provides new insights into the reciprocal nature of national movements. Increasingly, from 1868 to 1920, a bilateral flow of resources existed between national women's rights leaders and woman suffrage activists in Texas. Additionally, this study nationalizes the woman suffrage movement earlier than previously thought. Cross-regional woman suffrage activity has been marginalized by the belief that campaigning in the South did not exist or had not connected with the national associations until the 1890s. This closer examination provides a different view. Early woman's rights leaders aimed at a nationwide movement from the beginning. This national goal included the South, and woman suffrage interest soon spread to the region. One of the major factors in this relationship was that the primarily northeastern-based national leadership desperately needed southern support to aid in their larger goals. Texas' ability to conform and make the congruity politically successful eventually helped the state become one of NAWSA's few southern stars. National leaders believed the state was of strategic importance because Texas activists continuously told them so by emphasizing their promotion of women's rights. Tremendously adding credibility to these claims was the sheer number of times Texas legislators introduced woman suffrage resolutions over the course of more than fifty years. This happened during at least thirteen sessions of the Texas legislature, including two of the three post-Civil War constitutional conventions. This larger pattern of interdependency often culminated in both sides-the Texas and national organizations-believing that the other was necessary for successful campaigning at the state, regional, and national levels
Quantum Yield Calculations for Strongly Absorbing Chromophores

Siren songs or path to salvation? Interpreting the visions of web technology at a UK regional newspaper in crisis, 2006-11
A 5-year case study of an established regional newspaper in Britain investigates journalists about their perceptions of convergence in digital technologies. This research is the first ethnographic longitudinal case study of a UK regional newspaper. Although conforming to some trends observed in the wider field of scholarship, the analysis adds to skepticism about any linear or directional views of innovation and adoption: the Northern Echo newspaper journalists were observed to have revised their opinions of optimum Web practices, and sometimes radically reversed policies. Technology is seen in the period as a fluid, amorphous entity. Central corporate authority appeared to diminish in the period as part of a wider reduction in formalism. Questioning functionalist notions of the market, the study suggests cause and effect models of change are often subverted by contradictory perceptions of particular actions. Meanwhile, during technological evolution, the ‘professional imagination’ can be understood as strongly reflecting the parent print culture and its routines, despite pioneering a new convergence partnership with an independent television company
Identifying mRNA targets of microRNA dysregulated in cancer: with application to clear cell Renal Cell Carcinoma
BACKGROUND. MicroRNA regulate mRNA levels in a tissue specific way, either by inducing degradation of the transcript or by inhibiting translation or transcription. Putative mRNA targets of microRNA identified from seed sequence matches are available in many databases. However, such matches have a high false positive rate and cannot identify tissue specificity of regulation. RESULTS. We describe a simple method to identify direct mRNA targets of microRNA dysregulated in cancers from expression level measurements in patient matched tumor/normal samples. The word "direct" is used here in a strict sense to: a) represent mRNA which have an exact seed sequence match to the microRNA in their 3'UTR, b) the seed sequence match is strictly conserved across mouse, human, rat and dog genomes, c) the mRNA and microRNA expression levels can distinguish tumor from normal with high significance and d) the microRNA/mRNA expression levels are strongly and significantly anti-correlated in tumor and/or normal samples. We apply and validate the method using clear cell Renal Cell Carcinoma (ccRCC) and matched normal kidney samples, limiting our analysis to mRNA targets which undergo degradation of the mRNA transcript because of a perfect seed sequence match. Dysregulated microRNA and mRNA are first identified by comparing their expression levels in tumor vs normal samples. Putative dysregulated microRNA/mRNA pairs are identified from these using seed sequence matches, requiring that the seed sequence be conserved in human/dog/rat/mouse genomes. These are further pruned by requiring a strong anti-correlation signature in tumor and/or normal samples. The method revealed many new regulations in ccRCC. For instance, loss of miR-149, miR-200c and mir-141 causes gain of function of oncogenes (KCNMA1, LOX), VEGFA and SEMA6A respectively and increased levels of miR-142-3p, miR-185, mir-34a, miR-224, miR-21 cause loss of function of tumor suppressors LRRC2, PTPN13, SFRP1, ERBB4, and (SLC12A1, TCF21) respectively. We also found strong anti-correlation between VEGFA and the miR-200 family of microRNA: miR-200a*, 200b, 200c and miR-141. Several identified microRNA/mRNA pairs were validated on an independent set of matched ccRCC/normal samples. The regulation of SEMA6A by miR-141 was verified by a transfection assay. CONCLUSIONS. We describe a simple and reliable method to identify direct gene targets of microRNA in any cancer. The constraints we impose (strong dysregulation signature for microRNA and mRNA levels between tumor/normal samples, evolutionary conservation of seed sequence and strong anti-correlation of expression levels) remove spurious matches and identify a subset of robust, tissue specific, functional mRNA targets of dysregulated microRNA.Cancer Institute of New Jersy; New Jersey Commission for Cacner Research; Lineberger Comprehensive Cancer Center Tissue Procurement and Genomics Core Facility; Crawford Fun
