Abu Dhabi high school students’ interest in physics in different contexts was investigated with a survey conducted in connection with the international project, The Relevance of Science Education (ROSE). The sample consisted of 2248 students in public and private schools. Means of most items that belong to the school physics context for both girls and boys were below the score of (3.0). The most interesting topics for both genders were connected with fantasy items. The least interesting items (particularly for girls) were connected with artifacts and technological processes. Girls assigned the highest scores for “why we dream” and “life and death.” Boys assigned the highest scores for “inventions and discoveries” and “life outside of earth.” The main message of the study is that new curricular approaches and textbooks can be developed through combining technological and human contexts. The implications for curriculum development, teacher professional development programs, and other education strategies in Abu Dhabi are discussed in light of the ROSE survey. 相似文献

Hemoglobin E (beta-26Glutamic acid→Lysine) is the second most prevalent hemoglobin variant in the world. 293 blood samples from cases referred from several hospitals in the region of Andhra Pradesh were screened for the detection of hemoglobinopathies. Four samples were found to be in heterozygous state for Hb E condition. Mutation in two of these heterozygotes was analysed using a 722 base pair (bp) amplified DNA fragment from beta-globin gene and restriction enzyme Mnl 1. A 232bp DNA fragment was found to be associated with the Hb E mutation. 相似文献

The question of how academics in higher education institutions demonstrate they have the ability to teach and provide a high quality learning experience challenges the sector. Within this context, the use of professional dialogue for recognising teaching expertise is growing. This qualitative research explored how 16 academics valued their engagement in professional dialogue, and its impact as a developmental opportunity. The findings underline the importance of the relational and social aspects and value of this type of professional learning. 相似文献

Hypertension is the most important public health problem in developing countries and one of the major risk factors for cardiovascular
diseases, and it has been reported that hypertension is in part an inflammatory disorder and several workers have reported
elevated levels of CRP in hypertensive individuals. The main aim of the present study was to evaluate the association between
blood pressure and serum CRP levels across the range of blood pressure categories including prehypertension. A total of 104
patients and 63 control subjects were included in the present study. The level of CRP in the serum samples was estimated by
a high sensitivity immunoturbidometric assay. Standard unpaired student’s ‘t’ test was used for comparison of hs-CRP levels
between hypertensive patients and normotensive control subjects and between patient groups with different grades of hypertension
and different durations of hypertensive histories. The mean serum hs-CRP level in hypertensive patients was 3.26 mg/L compared
with 1.36 mg/L among normotensive control subjects (P<0.001). On comparison with normotensive control subjects, the hs-CRP
levels vary significantly both with grades and duration of hypertension, with most significant difference found in patients
with prehypertension (P<0.001), followed by Stage-I (P=0.01) and Stage-II(P=0.02) hypertensives. Significant difference in
hs-CRP levels was also found in patients with shorter duration of hypertensive history (≤ 1year) when compared with those
with ≥5 years of hypertensive history (P<0.01). Our study reveals a graded association between blood pressure and CRP elevation
in people with hypertension. Individuals with prehypertension or with shorter duration of hypertension (≤1 Year) had significantly
a greater likelihood of CRP elevation in comparison to chronic stage-I or stage-II hypertensives. 相似文献

This paper addresses the face recognition problem through a modification of the Fuzzy Fisherface classification method. In conventional methods, the relationship of each face to a class is assumed to be crisp. The Fuzzy Fisherface method introduces a gradual level of assignment of each face pattern to a class, using a membership grading based upon the K-Nearest Neighbor (KNN) algorithm. This method was further modified by incorporating the membership grade of each face pattern into the calculation of the between-class and within-class scatter matrices, termed as Complete Fuzzy LDA (CFLDA). The present work aims at improving the assignment of class membership by improving the parameters of the membership functions. A genetic algorithm is employed to optimize these parameters by searching the parameter space. Furthermore, the genetic algorithm is used to find the optimal number of nearest neighbors to be considered during the training phase. The experiments were performed on the Olivetti Research Laboratory (ORL) face image database and the results show consistent improvement in the recognition rate when compared to the results from other techniques applied on the same database and reported in literature. 相似文献

Novel influenza viruses are seen, internationally, as posing considerable health challenges, but public responses to such viruses are often rooted in cultural representations of disease and risk. However, little research has been conducted in locations associated with the origin of a pandemic. We examined representations and risk perceptions associated with swine flu amongst 120 Malaysian pig farmers. Thirty-seven per cent of respondents felt at particular risk of infection, two-thirds were somewhat or very concerned about being infected. Those respondents who were the most anxious believed particular societal "out-groups" (homosexuals, the homeless and prostitutes) to be at higher infection risk. Although few (4%) reported direct discrimination, 46% claimed friends had avoided them since the swine flu outbreak. Findings are discussed in the context of evolutionary, social representations and terror management theories of response to pandemic threat. 相似文献

The mobility of African students beyond national territories has become common worldwide. However, the underlying reasons motivating students to leave their countries of origin in pursuit of higher education in other developing nations and why these factors are important have not been fully explored. This study attempts to explore why and how African students travel to the United Arab Emirates for higher education. A push-pull factor theory of the international student’s choice of destination is developed to identify factors influencing the choices made by these students. The analytic hierarchy process is used to examine the relative importance of these factors. The findings of this quantitative study indicate that learning environment and geographic proximity are the two most important factors for African students, while other factors have a moderate impact. The findings contribute to a deeper and more comprehensive understanding of the needs and choices of existing and potential students from this continent, with a view to applying a segmentation approach to attract these students. 相似文献

Our attraction to another body increases if the body is symmetrical and in proportion. If a face or a structure is in proportion, we are more likely to notice it and find it beautiful. The universal ratio of beauty is the ‘Golden Ratio’, found in many structures. This ratio comes from Fibonacci numbers. In this article, we explore this concept along with its applications. 相似文献

The Community College Leadership Consortium is building the Bellwether Coalition for Instructional Leadership toward the development of a voluntary system of accountability for community colleges. In response to the Spellings Commission's national call for accountability in higher education, the consortium and its partners convened an Independent Policy Forum at the 2008 Community College Futures Assembly in Orlando, Florida. The Independent Policy Forum began to develop a set of recommendations to be communicated to the American Association of Community Colleges (AACC) during its 2009 annual meeting. Recommendations put forth by the forum will contain the founding principles for the nascent voluntary system of accountability for community colleges. 相似文献
