Urinary iodine levels in children (5–11 years) and in adult males and females (15–44 years) of three ecological zones (hilly, flood-prone and plains) of Bangladesh were analyzed to determine the status of biochemical iodine deficiency in the country. Data indicated that a large majority of the population all over Bangladesh have biochemical iodine deficiency urinary iodine excretion (UIE) less than the accepted cut-off level of 10 μg/dl. Adults were deficient to comparable degrees, 31.3% severely iodine deficient. The flood-prone zone was less affected: 71.7% children had iodine deficiency and 25% were severely deficient. Adults of this zone were less affected than the children. Iodine deficiency was least severe in the plain zone: 59.8% children were biochemically iodine deficient and of them 23.4% had UIE less than 2.0 μg/dl. In the case of the adults of this zone, 60.8% were biochemically iodine deficient and 20.6% had severe iodine deficiency. The results indicate that Bangladesh as a whole is an iodine deficient region, with the hilly zone being the most severely affected. Children were slightly more affected than the adults, and females were more affected than the males. 相似文献

An agenda-building model was examined for the question of Africaand terrorism. A path analysis compared real-world events (deathsand attacks attributed to terrorism), presidential emphasis,media coverage, and foreign aid for 20 African nations. Resultsshow a clear agenda-building trend—when nations were emphasizedwith a terrorism frame. Presidential emphasis of nationsinvolvement in terrorism influenced media coverage and the policyagenda. The findings also suggest that deaths attributed toterrorism influenced the news and policy agendas. Media coverageof nations with a terrorism frame influenced the policy agenda.Only one significant path coefficient was found in the analysisof agenda setting without terrorism framing: The more PresidentBush mentioned a nation in his public statements, the more TheNew York Times covered the country.

The purpose of this study was to translate the original version of the Epistemic Belief Inventory developed by Schraw, Bendixen, and Dunkle (2002) for pre-service teachers in a Turkish context and validate its construct. Studies on the epistemological beliefs of Turkish students have been heretofore limited in number and have been largely conducted using adapted versions of the Schommer (1990) instrument. First, the original questionnaire was translated from English to Turkish and then was scrutinized by experts in language, content, measurement, and evaluation. Then, the revised questionnaire was administered to 166 Turkish pre-service teachers. The results of exploratory factor analyses suggested 3 epistemological belief dimensions – quick learning, innate ability, and certain knowledge. The results of the study further revealed support for multidimensional theories of epistemological beliefs among pre-service teachers. In order to verify the results of the present study, further examination of pre-service teachers' epistemological belief systems is necessary. 相似文献
