Cytomorphometric analysis of squames from oral premalignant and malignant lesions

Objective: Oral cytology is becoming increasingly important in the early diagnosis of oral cancer, including epithelial atypia. The aim of this study is to assess the whether the cytoplasmic diameter, nuclear diameter and their nuclear to cytoplasmic ratio are reliable parameters in exfoliative cytology in detecting premalignant and malignant lesions. Study design: Cell and nuclear diameter were measured from the squames of normal buccal mucosal and of oral leukoplakia, oral submucous fibrosis, oral lichen planus which were histologically benign and oral squamous cell carcinoma were measured using an ocular micrometer disc. The nuclear to cytoplasmic ratio in each of these were deduced from the values obtained and compared with the controls which were age, sex and site matched. The data were evaluated using statistical methods, namely‘t’ test and analysis of variance. Results: We obtained a statistically significant reduction in the mean cytoplasmic and nuclear diameter in all the four groups. The nuclear to cytoplasmic ratio revealed to be significant only in group 1, 2 and 4. Conclusion: The present study suggests that a decrease in the mean cytoplasmic diameter of exfoliated buccal mucosal cells could serve as an early indicator of dysplastic change especially in lesions which appear histologically benign

Analysis of Environmental and Social Scores on Firm Profitability, Lending and Dividends in Germany and the UK

This paper aims to investigate the effects of separate components of corporate social responsibility—social and environmental efforts in particular—on a firm’s operating profit margin, dividends per share and net debt. It also investigates whether such efforts can reduce firm exposure to market risk. One or a combination of these factors may consequently be responsible for lower expected returns on firms with greater ES ratings. For this purpose we study firms on the FTSE-100 and the HDAX from the period 2002-2014. Environmental and social scores for these firms are regressed against operating profit margin, dividends per share and net debt while controlling for relevant factors. The firms are then divided into groups based on their environmental and social rankings and we compare the covariance of their returns with market returns to gauge the relation of their sensitivity (beta) to ES scores. The results of the first part of the study indicate that ES scores are more strongly correlated with OPM, Div/Share and Net debt in HDAX than in FTSE-100. In addition there is a slight positive correlation between firm beta and ES scores, implying increased exposure to market risk.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format

Special Considerations in Gifted Identification: Increasing Access and Equitable Practices for Underrepresented Populations in an Urban School District

Low-socio economic and/or minority students are substantially unidentified for gifted education programs. The disparities in gifted education for underrepresented students persist despite the growth in schools across the country of low income and minority students. Despite efforts to tackle equity issues in gifted education the large gaps of disproportionality persist. Explanations for this occurrence of underrepresentation is linked to the general processes for identifying gifted students, which are based largely on norm referenced standardized tests, with a single score criterion and a referral process that relies heavily on teacher and parent nominations. These identification processes tend to overlook the cultural needs and differences of students from underrepresented groups. Special consideration process as a tool to bridge the access and opportunity gap for underrepresented students in being identified as gifted is examined in this study. This hypothesis is studied using the experiences of a large urban school district following the introduction of a systematic special considerations process pilot in four schools with high representation of underrepresented populations

A Map Based on the Institutions, Asylums, Etc. Binder

This project creates a map that displays the real life locations of the institutions pictured in our Institutions, Asylums, Etc. binder’s postcards and creates a website that displays the information of the map and some of the information from Veronica Bagley’s project. The David P. Campbell Postcard Collection, searchable at postcard.uakron.edu, is a key collection of the CCHP’s Institute for Human Science and Culture. The collection provides the raw material for this project

Middle School Students Experiences with Personal Learning Devices as it Relates to Reading Motivation: A Case Study

The purpose of this collective case study was to understand the experiences of middle grades students as they relate to reading motivation with personal learning devices. The guiding question was, how do middle school students describe their experiences with personal learning devices as it relates to their motivation to read? The sample population included a total of 15 students from grades sixth, seventh and eighth from a North Georgia middle school. The psychological needs aspect of Deci and Ryan’s self-determination relevant to reading motivation and Rosenblatt’s transactional reading theory in regard to efferent and aesthetic reading transactions served as the theoretical basis for the research. Data was collected from multiple sources including individual interviews, ELA journals, reports from the reading platform myON® and focus group interviews. Data analysis consisted of coding and categorizing information that was then used to conduct a cross case synthesis. The themes of tools, focus, purpose, choice, voice and nonlinear reading were extrapolated and used to inform the naturalistic generalization that technology does not encourage students to read of their own volition. Instead, middle grade students are inclined to read with devices because the tools and features allow differentiation of the reading process on many levels. The results of this study substantiated the notion that technology is best utilized within the context of well-planned engaging instruction that takes into consideration the individual needs, capabilities, and preferences of each learner
