This paper presents a scalable digital learning system that can store and provide Web access to digital contents from voluntaries, teachers, and institutions that lack resources or expertise to offer classes over the Internet. We use the server-cluster architecture as a way to create scalable and highly available solutions. However, hosting a variety of contents from different owners on such a ...

This study aims to analyze the determinants of vertical integration (ownership and contract-ing) among peasant farmers in Northern Algeria. The choice of asset control is between ownership and a simple contracting. Thus, the integration of vertical stages of agricultural produc-tion leads to higher gross margins, influences the choice of marketing and supply channels, and improves market partic...

The study was undertaken to examine the socio-economic profiles of women participated in farms and rice mills activities; to examine contribution of women to household income which reducing their poverty; to identify the factors influencing the level of family income in farms and rice mills labourers; and to identify the problems and constraints of farms and rice mills.

Declining yields of maize as a result of Striga infestation has necessitated a new technology known as Imazapyr-resistant maize (IRM) to contain the problem. As a result, research and development initiatives with substantial participation of the private sector to transfer this new technology to farmers have been made in western Kenya. This study therefore assesses the adoption of IRM variety an...

BACKGROUND To date, there have been a limited number of studies on the impact of government-incentivised farm animal welfare programmes or 'schemes', and on farmers' attitudes regarding such schemes. In this study, focus groups were used to gain insight into Irish farmers' perceptions of such a scheme for suckler cattle and its behavioural impacts on farmers. RESULTS The findings were categor...

Vegetable production constitutes an important sub-sector of the agricultural economy of KwaZulu-Natal. Most vegetables are cultivated in mixed-cropping types of farming systems. The technical efficiency of vegetable based cropping systems was estimated in order to identify the potential increase in production without incurring additional costs. The factors affecting technical efficiency and con...

Agricultural extension workers’ service has been placed as the central pattern of agricultural transformation in general and smallholder farmers in particular. Due largely to this commensurately known trend, identifying factors that determine farmers’ access to extension workers’ service and the effect of the service on crop yield was found to be imperative. Cross sectional data was collected t...

The majority of data concerning the control of food intake in mammals is derived from studies of laboratory rats. Some ingestive controls, identified in rats, seem to operate identically in most farm species. Other controls, which have been identified in nonrodent species, appear to be absent in the rat. Thinking about the neural control of ingestion in agricultural species is based almost enti...

Rotator cuff disease, among others damage of the supraspinatus tendon mainly caused by work overload, is a common problem in the population resulting in a high incidence of sick leaves. In the present survey we sought to compare the need for sick leaves in relation to different stages of supraspinatus tendon affection and in relation to five different groups of workers. Our study counted with t...
