The global agricultural economy is changing. Commodity prices are declining, and producers increasingly supply complex value chains. There is growing interest in how farmers can benefit from emerging market opportunities. Farmers are encouraged to produce high value crops and engage in value-adding activities such as agro-processing. Farmer organization and collective action are often seen as k...

This paper describes an implementation of a large heterogeneous distributed parallel computation that counts the distribution of twin primes and calculates Brun’s constant and maximal distances between pairs of twin primes. Two primes are twins if they differ by two. It is not known if there are infinitely many twin primes but it was proven that the sum of their inverses converges to the value ...

In this brief rejoinder, we respond to Farmer, Monaghan, Misyak, and Christiansen (2011). We argue that the data still do not support the claim that reading time is affected by the phonological typicality of a word for its part of speech. We also question Farmer et al.'s claim that interleaving syntactic structures in an experiment modifies grammatically based syntactic expectations.

Understanding shallot seed systems is crucial for managing crop biodiversity on-farm where it of both private value to farmers and social significance future improvement the resilience farming system. Focus Group Discussion (FGD) was carried out in Cirebon-West Java, Brebes-Central Bantul-Yogyakarta S.R Nganjuk-East Java. In FGDs estimate that share formal sector total supply rarely exceeds 5%....

This study examines how smallholder coffee farmers’ perceptions may influence their engagement in peer mobilization and collective action. Forty farmers were interviewed the Central Highlands region of Peru using a closed-ended instrument. The sample was achieved purposive snowball sampling methods. Quantitative data on attitudes aspirations regarding working with peers, autonomy, external supp...

The flattening filter free (FFF) X-rays can provide much higher dose rate at the treatment target compared to the conventional flattened X-rays. However, the substantial increase of dose rate for FFF beams may affect the ion recombination correction factor, which is required for accurate measurements using ionization chambers in clinical dosimetry. The purpose of this work is to investigate the...
