In the context of educational transformation in South Africa the organic chemistry content of science textbooks needs to be mediated by the authors of the books profoundly and flexibly so as to provide for the diverse abilities and backgrounds of South African learners. This mediation requires critical interpretation of the curriculum documents [examination guidelines], representation and selection of the instructional ideas by using pedagogical content knowledge [PCK] so as to make the content accessible to the learners and to help them prepare for examinations. The purpose of this content analysis which used PCK as a theoretical framework was to establish how the grade12 organic chemistry content has been transformed for teaching and learning by the textbook authors and what teaching methods have been used, as not all the textbooks seem to cover the same content. To capture the PCK of the authors a representation of the content or CoRe was used for each of the books analysed using the Big Ideas from the text as well as the Bishop and Denley’s six knowledge bases of PCK. The study showed that although all the books analysed showed evidence of the authors’ PCK none of them mediated the content sufficiently to cater adequately for the learners’ needs.

Every year, thousands of Florida public high school graduates seek to enter Florida state colleges based on a single standardized placement test. This quantitative study sought to identify an actuarial model, based on multiple measures, as an alternative to standardized placement tests. The study, grounded on degree completion theories, examined high school students from the Miami-Dade metropolitan area and their performance in one first-year mathematics course in Miami Dade College during the Fall 2014 academic term. The study, using a sample size of 10,186 subjects, examined multiple predictor variables and one outcome variable to measure predictability of success in Intermediate Algebra. The study used descriptive statistics, multiple linear regression, and logistic regression to develop a multiple measure actuarial model. A quantitative analysis of archived student records was used in this study. The analysis revealed that the actuarial model, using gender, ethnicity, age, academic objective, academic load, high school GPA, high school mathematics gap, and high school mathematics curriculum composite score as predictor variables, was significant in predicting success in Intermediate Algebra. The actuarial model correctly classified 1,688 subjects who would fail Intermediate Algebra, achieving a hit rate of 75% in predicting failure in Intermediate Algebra. Similarly, the model achieved a hit rate of 54% when classifying subjects who would pass Intermediate Algebra. The improvement-over-chance index, I, was 44.8%, representing a 45% reduction in error when classifying subjects who would fail Intermediate Algebra. Thus, the actuarial model, with all its predictor variables, provides helpful guidance when advising incoming first-time-in-college (FTIC) students. / Includes bibliography. / Dissertation (Ph.D.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection

Globally there is a lack of radiologists, which results in unreported radiographic examinations, or a delay in reporting on radiographic images even in emergency situations. In order to mitigate and alleviate the situation, and optimise the utilisation of radiographers a red dot system was introduced in the United Kingdom, which later aided in the transformation of the role of radiographers in terms of formal reporting of various radiographic examinations. Although there is a shortage of medical practitioners and radiologists in South Africa the extended role of radiographers has not been yet realised for radiographers. At present, radiographers and medical practitioners work in collaboration to interpret and report on radiographic examinations informally, to facilitate effective and efficient patient management, but this is done illegally because the regulations defining the scope of the profession of radiography does not allow for such practice, putting radiographers and organisations at risk of litigation. In order to gain an in-depth knowledge of the phenomena, to enable the researcher to provide recommendations to the Professional Board of Radiography and Clinical Technology (PBRCT) of the Health Professions Council of South Africa (HPCSA), a qualitative, exploratory, descriptive, and contextual research study was undertaken. Radiographers and medical practitioners were interviewed in order to elicit rich descriptions of their experiences regarding reporting of trauma related radiographic images in the after-hours trauma units. Data were gathered using in-depth semi-structured interviews, and the data were analysed using kesch’s method of thematic synthesis. Three themes emerged from the data, namely the challenges radiographers and medical practitioners face in the after-hours trauma units respectively, with regards to reporting of trauma related adiographs, and suggestions were proposed to optimize the participation of radiographers with regard to trauma related radiographs in these units. A thick description and literature control was done using quotes from participants. Measures to ensure trustworthiness and ethical research practices were also implemented. Thereafter, recommendations were put forward for the PBRCT of the HPCSA, using current literature and inferences made from the findings of the study.

Currently 45.3% of cases diagnosed in Brazil are in an advanced stage worsening the prognosis. Therefore, the control of breast cancer should prioritize prevention and early detection through recommended tests: self examination (favoring corporal self) clinical examination and mammography as well as monitoring of the risk factors of this disease. Due to the close relationship between early diagnosis and improved prognosis this study aims to examine the practices of prevention of breast cancer in women aged 40 -69 years living in a community of São Luís - MA. This is a descriptive cross-sectional study with a quantitative approach performed in the period April to August 2014 with 265 women aged 40-69 years residing in the Town of Friars in Coroadinho in Maranhão São Luís. The results reveal that most of the women interviewed were aged 40-44 years (28.3%) incomplete primary education (40.4%) are married or in a stable relati onship (52.5%), brown (57, 7%) unemployed (49.8%) with family income less than minimum wage (55.5%). It was evidenced individual risk factors for breast cancer such as early menarche (22.6%) use of oral injectabl e or patch contraceptives (20%) nulliparity (2.6%) and late menopause (42.7%) makes TRH (20.6%). In the analysis of the environmental risk factors observed lower percentages of alcohol consumpt ion (35.1%) and smoking (21.1%) on the other hand the prevailing sedentary lifestyle (78.9%). The interviewees were overweight (44.9%) and abd ominal circumference greater than 88 cm (61.9%). Regarding preventive practice for early detection of breast cancer, considering the age range recommended for each examination, we observed the aged 40 to 49 years 73.1% underwent clinical examination followed by self-examination, while in women 50 and 69 years was the preferred mammography examination (68.3%). Women interviewed 53.2% reported illness in the last year most spontaneously sought medical care (87.6%) with the SUS primary health service referred (74.5%). We conclude that although there is good adherence to preventive practices for breast cancer the need for change in behavioral patterns that can be stimulated through the implementation of comprehensive and intersectoral measures, such as greater public disclosure of existing projects in the area aiming to stimulate physical activity, as this measure is a priority in the control of no ncommunicable chronic diseases such as breast cancer. / O câncer de mama é um problema de saúde pública cuja incidência vem aumentando vertiginosamente em praticamente todo o mundo. Atualmente 45,3% dos casos diagnosticados no Brasil já estão em estágio avançado, piorando os prognósticos. Portanto, o controle de câncer de mama deve priorizar ações de prevenção e detecção precoce através dos exames preconizados: o autoexame (favorecendo o autoconhecimento corporal), o exame clínico e a mamografia, além do monitoramento dos fatores de risco dessa patologia. Devido à estreita relação entre diagnóstico precoce e melhora no prognóstico da doença, o presente estudo visa estudar as práticas de prevenção do câncer de mama em mulheres na faixa etária de 40 a 69 anos, residentes em uma comunidade de São Luís - MA. Trata-se de um estudo descritivo, transversal, com abordagem quantitativa, realizado no período de abril a agosto de 2014, com 265 mulheres na faixa etária de 40 a 69 anos residentes na Vila dos Frades no Coroadinho, em São Luís - Maranhão. Os resultados revelam que a maioria das mulheres entrevistadas tem idade entre 40 a 44 anos (28,3%), ensino fundamental incompleto (40,4%), são casadas ou em união estável (52,5%), pardas (57,7%), desempregadas (49,8%), com a renda familiar menor que um salário mínimo (55,5%). Não foi evidenciado fatores de risco individuai s para câncer de mama como menarca precoce (22,6%), uso de anticoncepcional oral, injetável ou adesivo (20%), nuliparidade (2,6%), menopausa tardia (42,7%), faz TRH (20,6%). Na análise dos fatores de risco ambientais observaram-se baixos percentuais de etilismo (35,1%) e tabagismo (21,1%), por outro lado, prevalece o sedentarismo (78,9%). As entrevistadas estavam com sobrepeso (44,9%) e a circunferência abdominal acima de 88 centímetros (61,9%) . Quanto à prática preventiva para detecção precoce do câncer de mama, considerando a faixa etária preconizada para cada exame, observou -se a na faixa etária de 40 a 49 anos 73,1% realizaram o exame clínico seguido do autoexame, enquanto que em mulheres entre 50 e 69 anos a mamografia foi o exame preferencial (68,3%). Das mulheres entrevistadas, 53,2% relataram adoecimento no último ano, a maioria procurou espontaneamente assistência médica (87,6%), sendo o SUS o principal serviço de saúde referido (74,5%). Conclui-se que apesar de boa adesão às práticas preventivas do câncer de mama, há necessidade de mudança nos padrões comportamentais que podem ser estimulados através da implementação de medidas abrangentes e intersetoriais, como a maior divulgação de projetos públicos existentes na área, visando estimular a prática d e atividade física, pois essa medida é prioritária no controle de doenças crônicas não transmissíveis, a exemplo do câncer de mama.

The importance given to vocabulary in second language instruction and in theories of second language acquisition has increased greatly in the last fifteen years. It is thus important for second language teachers/researchers to have valid, useful methods of assessing the vocabulary needs and vocabulary knowledge of their students as well as valid and useful methods of assessing the efficacy of various methods and techniques of teaching and learning vocabulary. This study examines the usefulness and validity of a relatively new type of checklist vocabulary test method known as the 'YES/NO' method. In the YES/NO method, nonsense words are listed together with real test words. A subject's test score is calculated by applying both the percentage of real words checked and the percentage of nonsense words checked to a mathematical formula. Sixty-six students enrolled in a college-level Englishfor- academic-purposes (EAP) program took three vocabulary tests. Correlation was calculated between the participants' scores on the 'Structure' and 'Listening' subsections of the Comprehensive English Language Test (CELT) and the participants' scores on all three vocabulary tests scored both as YES/NO tests and as simple-checklist tests. The following three findings were noteworthy: (1) correlation between CELT subtest scores and vocabulary test scores was more consistent and stronger when the vocabulary tests were scored as simple-checklist tests compared to when they were scored as YES/NO tests, (2) few students scored above recommended exit-level scores on the CELT subtests but below 5,000 on the vocabulary tests, and (3) a 120-real-word vocabulary test correlated more consistently and strongly with the CELT subtests than either of two 60-real-word vocabulary tests. Three conclusions were made: (1) adult EAP students preparing to study at English-medium institutions of higher education need knowledge of the 5,000 most-frequent words [lemmas] of English, (2) the YES/NO method of testing the L2 vocabulary knowledge of adult EAP students is not better than the simple-checklist method, and (3) a good direction for work on the improvement of tests intended to measure the L2 vocabulary knowledge of adult EAP students may be to explore how to elicit valid responses on long simple-checklist tests.
