Towards a mathematical system for extension education

A system of equations describing the relationship of change agent in extension education and client (e.g. a leader of a local community) is presented. The main task of the former is to ensure that he is able to transfer information to the latter, also learning difficulties involved and passing them into institutions of higher learning

Towards a mathematical system for extension education - II

A brief description is given of a mathematical model for use in extension education regarding fisheries in developing countries

Extent of trial of improved designs of lobster traps

The mean extent of trial of an improved design of lobster trap by 45 fishermen was 26.46. The cost of local traps and number of seasons used were both significantly negatively associated with the extent of trials; its relationship with the annual catch by indigenous trap approached significance. These three variables accounted for 59% of the variance in the extent of trial

Discriminant analysis of selected variables in the adoption of fish curing

Discriminant functions were worked out for adoption or non-adoption of five improved practices in fish curing. Four variables measured quantitatively formed the basis for discrimination. In four out of five equations, the selected variables were found to discriminate significantly between the adopters and non-adopters

Analysis of dimensions involved in the option of improved fish curing practices

A statistical analysis was made of the dimensions involved in the adoption of improved fish curing practices

On further improvement of the techinque of evaluating summer institutes

Data from an earlier study are reanalyzed to improve upon the evaluation measures of summer institutes. The Summer Institute Efficiency Index is improved by using weighted geometric mean using different ranks as weights for the several dimensions. The coverage utility index is improved by taking the ratings given by all the participants

Evaluation of a summer institute on fish processing technology

The utility of Summer Institute Efficiency Index (SIEI) is demonstrated using data from evaluation of a summer institute in fish processing. The SIEI worked to 76.16 showing high efficiency rating. The acquisition of skills appears to be independent of coverage and utility perception. The three dimensions of evaluation correlate highly with SIEI

Training needs of traditional marine fishermen in Kerala

Training needs of 80 fishermen in 25 subject areas revealed a mean training need score of 23.0l; 95% wanted to get trained. The training needs were fairly strong in all subject areas, with the highest demand being for fishery engineering. Training need was also high for areas related to fishery technology. Most of the fishermen preferred to have the training at their own village, and in the months of June or July for an average period of 20.85 days. Education and income were positively related to intensity of training needs whereas age, number of family members, number of employed family members and experience in fishing were negatively correlated with it. These six variables explained 27 of the variance in training need intensity

Effect of mass media on the adoption of fish curing

A study of two factors with two-way classification shows that the main effect of newspaper subscription on the adoption of improved practices in fish curing is significant. The effect of radio ownership appears to be masked by newspaper subscription. The interaction between the two factors was not significant. The study confirms the importance of mass media in adoption

Adoption of CIFT fishing boat designs

Information about the adoption of CIFT fishing boat designs was collected from 54 boat building yards of the country. The majority of the boats were built as per CIFT designs. The types of wood used and the designs were dependent upon each other. Other variables studied did not show significant effects upon the type of adoption. The CIFT designs were modified at some yards and these details are discussed
