Globally, ministries of agriculture, universities, and the private sector employ more than 600,000 extension agents (Swanson, Farmer, and Bahal 1990). In the past, extension services, largely public, were equated with the transfer of agricultural production technology in pre-determined “packages”. Extension systems are now understood to be much broader and more diverse, including public and pri...

Information systems relate to diverse applications, but, until recently, the use of this technology in agriculture and environment has been relatively behind the applications in the industrial sector. The publication of IJAEIS started in 2010 in order to promote the new research advances in information systems applied to agriculture and environment. This paper presents an overview of the differ...

Surveillance measures for human cases of Lyme disease in Wisconsin were compared and associated with tick distribution and vegetation coverage. During 1991-1994, 1,759 confirmed human cases of Lyme disease reported to the Wisconsin Division of Health were assigned a county of residence, but only 329 (19%) could be assigned with certainty a county of exposure. Distributions of cases by county of...

introduction: hospitals require a central monitoring and improve planning process in order to enhance patient care quality. regarding the current developments in health care systems, the question is which information system can support transformation of hospitals. this review article focuses on the capacity of enterprise resource planning (erp) systems for the transformation of hospitals. metho...

conclusions: the results of the present research indicates that the emphasis of the his evaluation moves from technical subjects to human and organizational subjects, and from objective to subjective issues. therefore, this issue entails more familiarity with more qualitative evaluation methods. in most of the reviewed studies, the main focus has been laid on the necessity of using multi-method...

This paper uses the introduction of barbed wire fences to the American Midwest in the late 19th century to estimate the effects of property rights on farmers’ production decisions. Farmers were both formally and informally required to build fences to secure exclusive land-use rights, yet preferred wooden fences had been prohibitively expensive in areas with little woodland. The introduction and...

The primary goal of our research is to develop key elements of a precision agriculture program applicable to high-value woody perennial crops, such as cranberries. These crop systems exhibit tremendous variability in crop yields and quality as imposed by variations in soil properties (water availability and nutrient deficiency) that lead to crop stress (disease development and weed competition)...
