Agricultural Service Firms: Organizational Characteristics and Linkages to Production Agriculture

Using data from the 1978 Census of Agriculture and the 1978 Census of Agricultural Services, this paper examines some of the organizational characteristics of firms in seven agricultural service industry subgroups. Using the 48 contiguous states as units of analysis, an ecological analysis attempts to identify structure characteristics of farm systems that give rise to, and foster development of, off-farm agricultural service firms. Results show that considerable variation exists in the organizational and labor force characteristics across the seven industry subgroups. Other findings indicate that the spread of agricultural services in a state is positively associated with the proportion of farmland controlled by nonfamily corporations and with large-scale farming. Energy intensity and mechanization, on the other hand, are inversely correlated with the incursion of agricultural services in a state. Recommendations for future avenues of research in this area are offered

CIVIC COMMUNITY APPROACHES TO RURAL DEVELOPMENT IN THE SOUTH: ECONOMIC GROWTH WITH PROSPERITY

The free market-based policies of the corporate community model have skewed economic development across the South. For many small, rural communities, the consequences of global capitalism have resulted in declining real wages, high underemployment, and increasing rates of income inequality. Backed by recent scholarship and grassroots movements that suggest both civic engagement and the presence of smaller-scale, locally controlled enerprises can help determine whether communities prosper or decline, this paper explores the links between social structure and rural development in the South. The goal is to expand our understanding of civic community theory as an alternative to the neoclassical economic model of development. Using a local problem-solving framework, we suggest that a departure from the traditional, neoclassical path of development is in order. We conclude that rural policy makers must establish a role for civic community in the rural development process if they wish to protect the welfare of workers and communities, while increasing the prospects of economic growth with prosperity.civic community, economic growth, rural development, social capital, Southern United States, Community/Rural/Urban Development, R11, O21, R58,

Reptilian Heart Development And The Molecular Basis Of Cardiac Chamber Evolution

The emergence of terrestrial life witnessed the need for more sophisticated circulatory systems. This has evolved in birds, mammals and crocodilians into complete septation of the heart into left and right sides, allowing separate pulmonary and systemic circulatory systems, a key requirement for the evolution of endothermy(1-3). However, the evolution of the amniote heart is poorly understood. Reptilian hearts have been the subject of debate in the context of the evolution of cardiac septation: do they possess a single ventricular chamber or two incompletely septated ventricles(4-7)? Here we examine heart development in the red-eared slider turtle, Trachemys scripta elegans (a chelonian), and the green anole, Anolis carolinensis (a squamate), focusing on gene expression in the developing ventricles. Both reptiles initially form a ventricular chamber that homogenously expresses the T-box transcription factor gene Tbx5. In contrast, in birds and mammals, Tbx5 is restricted to left ventricle precursors(8,9). In later stages, Tbx5 expression in the turtle (but not anole) heart is gradually restricted to a distinct left ventricle, forming a left-right gradient. This suggests that Tbx5 expression was refined during evolution to pattern the ventricles. In support of this hypothesis, we show that loss of Tbx5 in the mouse ventricle results in a single chamber lacking distinct identity, indicating a requirement for Tbx5 in septation. Importantly, misexpression of Tbx5 throughout the developing myocardium to mimic the reptilian expression pattern also results in a single mispatterned ventricular chamber lacking septation. Thus ventricular septation is established by a steep and correctly positioned Tbx5 gradient. Our findings provide a molecular mechanism for the evolution of the amniote ventricle, and support the concept that altered expression of developmental regulators is a key mechanism of vertebrate evolution

A review of the fossil record of turtles of the clade Pan-Carettochelys

Turtles of the total clade Pan-Carettochelys have a relatively poor fossil record that extends from the Early Cretaceous. The clade is only found in Asia during the Cretaceous, but spreads to Europe and North America during the Eocene. Neogene finds are restricted to Europe, Africa and Australia, whereas the only surviving species, Carettochelys insculpta, lives in New Guinea and the Northern Territories of Australia. The ecology of fossil pan-carettochelyids appears similar to that of the extant C. insculpta, although more primitive representatives were likely less adapted to brackish water. Current phylogenies only recognize three internested clades: Pan- Carettochelys, Carettochelyidae and Carettochelyinae. A taxonomic review of the group concludes that of 25 named taxa, 13 are nomina valida, 7 are nomina invalida, 3 are nomina dubia, and 2 are nomina nuda

Real Incomes of Rural Black and Hispanic Workers Fell Further Behind in the 1980's

The economic rebound in the 1980's left most rural areas behind, especially those in the South and West with large concentrations of blacks and Hispanics. While urban incomes for white men rose a little more than 1 percent in real terms from 1979-87, rural incomes declined by nearly 3 percent for white men, about 13 percent for black men in the rural South, and 16 percent for Hispanic men in the rural West

Factors Related to the Adoption of rBST Among a Population of Farmers in Ontario County, New York

A population of 50 dairy farms in Upstate New York was surveyed in 1993 to collect data on the organizational and structural characteristics of their farm businesses and households, including information about their attitudes towards rBST. In the fall of 1994, six months after rBST was approved for general use, this same population of farmers was resurveyed. Findings show that in 1994 one-half of the farmers were using rBST or planned to use it within one year. Compared to non-adopters, farmers who adopted rBST were generally larger, used more advanced dairy technologies, and reported higher production herd averages. Differences in attitudes and goals were also observed. Implications of rBST for the future organizational structure of New York dairies are discussed
