Abstract: Covariance measures the dependence between two or more random variables. Stock market is a population consist mutually exclusive subsets (business sectors). Elements within these subsets are homogeneous in nature of business and heterogeneous between subsets. These sub sets or elements of the sub sets are not independent. Therefore occurrence or non occurrence of one event may depend on the others. This study focused on identifying the covariance structure of the Sri Lankan share market and making use it for forecasting returns. Covariance between   individual company returns, sector returns and total market returns were studied and regression analysis was conducted between variables with significant relationships.

Keywords: Covariance, correlation, homogeneous, heterogeneous, independent, mutually exclusive.

Abstract: This paper is part of a broad study that looked at the impact of hearing loss on literacy skills development. The paper explores the role of the home and the school in the development of literacy skills among learners with hearing impairments. The study employed mixed methods where both qualitative and quantitative techniques were used. However, the case study design largely underpinned the study.  The representative sample was composed of five educators (two teachers and three administrators) and 10 parents who were conveniently selected. Questionnaires, interviews and observation were the data gathering tools used. The results showed that no workshops were ever held to staff develop teachers on the teaching of students with hearing impairment. There was also no meaningful communication and direct contact between teachers of the deaf and parents of deaf children. The present curriculum does not support both English and Zimbabwe Sign Language needed for literacy development in student with hearing impairments. The study recommended that educators must be provided with solid training in Special Needs Education, at both pre-service and in-service levels. It was also recommended that Language development should be the primary consideration when teaching students who are pre-lingually deaf (either born deaf or became deaf before acquiring language). 

Keywords:  literacy development, hearing impairment, sign language, deaf, educators.
