A Discriminant Analysis of Factors Associated with The Adoption Of Certified Organic Farming By Smallholder Farmers in Kwazulu-Natal, South Africa AgEcon
Kisaka-Lwayo, Maggie.
Discriminant analysis was used to identify the characteristics that distinguish between fully-certified organic, partially-certified organic and non-organic farmers in Umbumbulu district, KwaZulu-Natal (KZN), South Africa (SA) during October- November 2004. 200 farmers interviewed were drawn by purposively selecting the 151 members of the Ezemvelo Farmers’ Organisation (EFO), and by random sampling 49 non-organic farmers in wards neighbouring EFO. Results from the two estimated discriminant functions suggested that farmers with higher household sizes, incomes, input costs per hectare and number of chickens owned, locations further from innovators and less risk aversion were more likely to be certified as organic. Household location should be considered in...

Femoral Functional Adaptation: A Comparison Between Hunter Gatherers and Farmers Using Geometric Morphometrics International Journal of Morphology
Püschel,Thomas A; Benítez,Hugo A.
The transition from hunting and gathering to agriculture has been associated with a gracilization in human form, especially in long bones. This has been interpreted as result of an increasingly sedentary lifestyle and reduced workload in the farming populations. However the majority of these evidences have been based on the application of different biomechanical techniques or the qualitative assessment of distinct morphological traits on attachment sites. Hence, this study tried to address whether is possible to distinguish between two different populations (hunter-gatherers and farmers) by quantifying their femoral morphology applying geometric morphometrics. We compared 16 male left femora belonging to two populations of Native Americans from the same...

Food Security and Poverty of the Rural Households In Kwara State, Nigeria AgEcon
Omotesho, O.A.; Adewumi, Matthew Olaniyi; Fadimula, K.S.
A fundamental challenge the world faces today is ensuring that millions of households living in poverty have access to enough food to maintain a healthy life. Africa over the years has been looking for ways to solving the problem of food security and it is an important topic in discussions of Africa leaders. While there are national data on food security and poverty, information on rural food security and poverty are not readily available especially in Nigeria. This study, therefore, employed discriminant analysis to examine the levels and the major determinants of food security and poverty among the rural households who are the major producers of food in Nigeria. Using the basic calorie and protein requirement per capita of households, our result revealed...

Sexual size dimorphism in Black-Browed Albatross (Diomedea melanophris) incidentally killed during longline operations Hornero
Gandini,Patricia; Frere,Esteban; García,M. Fernanda; Seco Pon,Juan P..
Black-Browed Albatross (Diomedea melanophris) displays little sexual dimorphism and although males are usually larger than females, sexing birds by direct observation is difficult. We evaluated sexual size dimorphism in this species and provided a reliable method to predict the sex of measured birds. Discriminant Analysis of six morphometric measurements of adult birds indicated that only three variables (bill depth, head width and nape) were the most accurate variables to use in a discriminant function model, predicting sex with 87% of reliability.
