This paper investigates mechanisms for the private provision of a public good which utilize competition to incentivize contributions. Theory predicts that “all-pay” competition is particularly effective for fundraising. Within this class of mechanisms different types of lotteries and all-pay auctions are analyzed and ranked. Four all-pay competition mechanisms are then examined in a laboratory ...

BACKGROUND Leadership is critical to making changes at multiple levels of the social ecological model, including the environmental and policy levels, and will therefore likely contribute to solutions to the obesity epidemic and other public health issues. The literature describing the relative leadership styles and strengths of women versus men is mixed and virtually all research comes from sec...

Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of human morbidity and mortality worldwide. The emergence in the last decade of a livestock-associated MRSA (LA-MRSA) clone which also has the capacity to cause zoonotic infections in humans has raised important questions regarding its origin and its potential to cause human epidemics. An important study by L. B. Price et al. [...

This study analyzed the influence of sustainable livelihood and environmental cognition on herdsmen’s production behaviors basis logistic model. The consequences illustrated that social capital followed by material capital, financial human has greatest impact behaviors, but natural played a vital role in promoting choice raising breeding scale. area quality grassland herdsman families’ could en...

husbandry practices in the United States have been industrialized, resulting in an increased number of large corporate and contract livestock operations raising thousands of animals in a single facility. Industrialized farms achieve economies of scale through specialization, increased size, and close confinement that allows high animal densities on relatively small land areas (1,2). These chang...

African swine fever (ASF) is rapidly becoming a grave threat to international livestock raising and pork production (I). During 1978 new foci of ASF appeared in Latin America, Malta, and Sardinia (2). The Latin American outbreaks do not appear to have followed the course of a previous outbreak on Cuba (3), during which the disease was eliminated relatively fast. Instead, ASF now appears establi...

Hydatid disease is a common parasitic infestation caused by the parasite Echinococcus granulosus. It is a serious health problem most frequently encountered in rural areas where domestic livestock-raising is common. Complete surgical excision is the gold standard treatment for hydatid cyst. Postoperative medical treatment with antihelminthic drugs (benzimidazole derivatives) are frequently comb...

There is concern that livestock operations for fattening cattle and raising hogs known as concentrated animal feeding operations (CAFOs) release substances into the air that have negative effects on the health of persons living nearby. These substances include dust containing endotoxin and other microbial products as well as ammonia, hydrogen sulfide and a variety of volatile organic compounds....

Although a "One Health" approach has been successfully implemented for emerging infectious zoonotic diseases with pandemic potential, we still lack a conceptual framework to address enzootic diseases like brucellosis. The vast majority of published brucellosis studies in the developing world rely solely on serology. An important shortcoming of brucellosis serology is the impossibility to infer ...
