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

Food Availability and Food Deserts in the Nonmetropolitan South

Over the past thirty years, the structure of food retailing in the United States has changed dramatically. Local grocery stores that once served a small community or neighborhood are increasingly being replaced by regional or national chain grocers. In addition, big box general merchan- disers have also entered the retail grocery sector with the advent of hybrid superstores that combine groceries with a wide array of product lines. A key consequence of this restructuring is the growing uneven distribution of food retailers across rural America. For example, Kaufman reports that rural counties in the Lower Mississippi Delta average one supermarket per 190.5 square miles. Additionally, over 70 percent of the low income populations in this region must travel 30 or more miles to access the lower food prices offered by a supermarket or large grocery store. The remaining options included small grocers or convenience stores where consumers are likely to pay substan- tially higher prices for a smaller variety of lower quality foods [7]

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,

Effects of Biannual Azithromycin Mass Drug Administration on Malaria in Malawian Children: A Cluster-Randomized Trial.

Reductions in malaria morbidity have been reported following azithromycin mass drug administration (MDA) for trachoma. The recent Macrolides Oraux pour Reduire les Deces avec un Oeil sur la Resistance (MORDOR) trial reported a reduction in child mortality following biannual azithromycin MDA. Here, we investigate the effects of azithromycin MDA on malaria at the MORDOR-Malawi study site. A cluster-randomized double-blind placebo-controlled trial, with 15 clusters per arm, was conducted. House-to-house census was updated biannually, and azithromycin or placebo syrup was distributed to children aged 1-59 months for a total of four biannual distributions. At baseline, 12-month, and 24-month follow-up visits, a random sample of 1,200 children was assessed for malaria with thick and thin blood smears and hemoglobin measurement. In the community-level analysis, there was no difference in the prevalence of parasitemia (1.0% lower in azithromycin-treated communities; 95% CI: -8.2 to 6.1), gametocytemia (0.7% lower in azithromycin-treated communities; 95% CI: -2.8 to 1.5), or anemia (1.7% lower in azithromycin-treated communities; 95% CI: -8.1 to 4.6) between placebo and azithromycin communities. Further interrogation of the data at the individual level, both per-protocol (including only those who received treatment 6 months previously) and by intention-to-treat, did not identify differences in parasitemia between treatment arms. In contrast to several previous reports, this study did not show an effect of azithromycin MDA on malaria parasitemia at the community or individual levels

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
