Telecommunications demand and spectrum management policy

The allocation of electromagnetic spectrum involves a substantial level of controversy both in the United States and Abroad. One often finds this controversy as an emotional one, especially because a multitude of variables that must be considered make it extremely difficult to evaluate competing requirements. This study explores certain verifiable methodology to forecast telecommunications demands for developing sound spectrum management policies.     

White wool,the growth of the ancient dye industry and an expanding colour vocabulary

The possible stimulus to the dye industry in antiquity provided by the breeding of sheep with a white fleece is linked to the development of a colour vocabulary apparent in ancient texts.     

Vocational training in the use of new technologies for people with disabilities

Following a brief review of the literature, details are given of an in-depth evaluation of a computer training centre called Microjob. This facility set out to integrate computer training, vocational guidance, functional assessment, placement in employment and post-placement support into a single service delivery package. In this paper the facility's outcome record is examined in relation to targets set for it, consideration is given to the special needs of home-based trainees, and specific difficulties faced by the project (including an inefficient management structure, inadequate staff training and a poor level of awareness of clients' special needs) are discussed.     

Feasibility of Manufacturing A Solid Dosage Form Using A Liquid Nonvolatile Drug Carrier: A Physico-Chemical Characterization

Experiments were performed to determine the formulation and manufacturing feasibility of three model solid capsule formulations using a spray-on liquid drug carrier. Methylparaben was used as a model low-dose drug in the liquid drug carrier. Formulations containing different amounts of liquid drug carrier were successfully encapsulated on the H&K 400 capsule filling machine. The formulations contained varying ratios of liquid (methylparaben-propylene carbonate solution) to solid (compressible sugar, NF), which ranged from 10.0 - 20.0 μL/450 mg. Physical characteristics (i.e. weight variation, dissolution, etc.) of the filled capsules were evaluated. The 20.0 μL liquid/450 mg solid ratio was found to be the best hard gelatin capsule formulation based upon its rapid dissolution profile and was equivalent to all other formulations tested with respect to weight variation and content uniformity.

Analogical reconstruction of the probability knowledge of Zimbabwean female secondary school students

Abstract

Analogies were used to facilitate reconstructing the probability knowledge of 54 culturally diverse, female, Zimbabwean secondary school students in cases where there were misconceptions in their comprehension of probability. Ten contextually appropriate misconception‐prone target situations were generated, together with their conceptually analogous counterparts, known as source or anchoring situations. The source analogues were designed to draw out those areas where student beliefs agreed with accepted mathematical theory. Students’ responses to the target situations indicated that probability misconceptions were common and that the source analogues were effective in providing anchors for mathematically correct ideas. The participants were interviewed and knowledge reconstruction was attempted using the source analogues. A success rate of 0.88 was achieved. Testing after one month indicated a stability rate of 0.82 for the reconstructed probability knowledge.
