The Euglenida consists mostly of free-living flagellates with very diverse modes of nutrition. A number of heterotrophic euglenids (e.g., Petalomonas and Ploeotia) are limited to bacteriotrophy (Fig. 1a–c) while others (e.g., Dinema and Peranema) are capable of ingesting eukaryotic prey (Fig. 1f). We use the label “eukaryotroph” to distinguish the latter taxa from the bacteriotrophs (Triemer an...

An application-level technique is described for farmer-worker parallel applications which allows a worker to be added or removed from the computing farm at any moment of the run time without affecting the overall outcome of the computation. The technique is based on uncoupling the farmer from the workers by means of a separate module which asynchronously feeds these latter with new “units of wo...

This paper proposes a methodological approach for eliciting farmers' utility functions. The methodology is non-interactive, in that the parameters defining the utility function are obtained by observing the actual behaviour adopted by farmers without resorting to the use of questions on random lotteries. The methodology recognises that the farmer attempts to achieve several objectives, most of ...

— This article investigates determinants and impacts of cooperative organization, using the example of smallholder banana farmers in Kenya. Farmer groups are inclusive of the poor, although wealthier households are more likely to join. Employing propensity score matching, we find positive income effects for active group members. Yet price advantages of collective marketing are small, and high-v...

An epidemiological and molecular investigation of a cutaneous suppurative infection with Staphylococcus aureus in a dairy farmer, occurring concurrently with an outbreak of clinical mastitis in his herd, was carried out. A common aetiology for the diseases in the farmer and his cows was established by combining clinical evidence with a molecular genomic analysis of the bacterial isolates using ...

This paper assesses the effectiveness of the traditional models of co-operation and analyses best practice in collaboration between farmers seeking to gain significantly greater scale and flexibility in an increasingly global food chain. By drawing upon broader strategic management thinking and relevant international practice, the study seeks to identify new models for farmer collaboration. The...

Timing nitrogen applications to the biological needs of a crop is an effective way to reduce nitrogen losses to the environment. However, this strategy may carry a production risk and conflict with farmers' economic objectives. A field-level production decision model was used to estimate on-farm costs associated with timing nitrogen applications for crop needs in Indiana. For a risk-neutral far...
