Role of Explicit Teaching of Cognitive/Metacognitive Reading Strategies to Improve Reading Comprehension at the Elementary Level

This paper presents a summary of selected research on teaching cognitive and metacognitive reading strategies and their correlation to improved reading comprehension at the elementary level. It also reviews instructional programs, and describes implications for teaching. Study findings indicate that explicit teaching of cognitive/metacognitive reading strategies are effective in improving reading comprehension for students at the elementary level

Washburn extraction and width of the IUE point spread function

The Washburn Extraction Routine for low dispersion IUE spectra was reviewed. The shape of the point spread function (PSF) in low dispersion spectra is sufficiently well described by a gaussian function. The PSF is in large and small aperture essentially identical and values of sigma are presented. Several advantages of the extraction routine are mentioned

Evaluating the Effectiveness of Alternative Extension Methods: Triple-Bag Storage of Cowpeas by Small-Scale Farmers in West Africa

This study examined two questions related to the adoption of triple-bag storage technology for farmers storing cowpeas in West Africa. First the effect of an extension program, focused on village demonstrations, on adoption was considered. Second, the effect of radio messages to augment this extension program was analyzed. The results indicate that adoption was positively affected by the extension program and radio messages do augment the effectiveness.Effective extension methods, cowpeas, hermetic storage, Teaching/Communication/Extension/Profession,

CONSUMER ACCEPTANCE OF GMO COWPEAS IN SUB-SAHARA AFRICA

Cowpea is the most important indigenous African grain legume for both home use and as a cash crop. Because of its tolerance to drought it is especially important for the Sahel. Genetic transformation of cowpea with Bachilius Thurengius (Bt) genes to control pod boring insects has many advantages, but little is known of the potential consumer response. This paper analyzes and reports the results of a survey of 200 consumers in northern Nigeria in early 2003 concerning consumer awareness of and acceptance of biotechnology. Ninety percent of the respondents were aware of GM products. Those respondents who were most concerned about the ethics of genetic transformation were likely to disapprove of such products, while those individuals who identified international radio as an information source were more likely to approve of GM technology.Institutional and Behavioral Economics,

The Georgia Tech High Sensitivity Microwave Measurement System

As observations and models of the planets become increasingly more accurate and sophisticated, the need for highly accurate laboratory measurements of the microwave properties of the component gases present in their atmospheres become ever more critical. This paper describes the system that has been developed at Georgia Tech to make these measurements at wavelengths ranging from 13.3 cm to 1.38 cm with a sensitivity of 0.05 dB/km at the longest wavelength and 0.6 db/km at the shortest wavelength

Study of leakage currents in pCVD diamonds as function of the magnetic field

pCVD diamond sensors are regularly used as beam loss monitors in accelerators by measuring the ionization of the lost particles. In the past these beam loss monitors showed sudden increases in the dark leakage current without beam losses and these erratic leakage currents were found to decrease, if magnetic fields were present. Here we report on a systematic study of leakage currents inside a magnetic field. The decrease of erratic currents in a magnetic field was confirmed. On the contrary, diamonds without erratic currents showed an increase of the leakage current in a magnetic field perpendicular to the electric field for fields up to 0.6T, for higher fields it decreases. A preliminary model is introduced to explain the observations.Comment: 6 pages, 16 figures, poster at Hasselt Diamond Workshop, Mar 2009, accepted version for publicatio
