Ownership, access and sequential investment

We extend the property-rights framework to allow for: a separation of the ownership rights of access and veto; and sequential investment. Parties investing first (ex ante) do so before contracting is possible. Parties that invest second (ex post) can contract on (at least some) of their investment costs. Along with this cost-sharing effect, the incentive to invest is affected by a strategic effect generated by sequential investment. Together these effects can overturn some of the predictions of the property-rights literature. For example, the most inclusive ownership structure might not be optimal, even if all investments are complementary

Quantum dots coordinated with conjugated organic ligands: new nanomaterials with novel photophysics

CdSe quantum dots functionalized with oligo-(phenylene vinylene) (OPV) ligands (CdSe-OPV nanostructures) represent a new class of composite nanomaterials with significantly modified photophysics relative to bulk blends or isolated components. Single-molecule spectroscopy on these species have revealed novel photophysics such as enhanced energy transfer, spectral stability, and strongly modified excited state lifetimes and blinking statistics. Here, we review the role of ligands in quantum dot applications and summarize some of our recent efforts probing energy and charge transfer in hybrid CdSe-OPV composite nanostructures

Effect of supplementation diets of slipery fish level fat on performance, milk yield and milk composition of F1 (Landrace X Yorkshire) sows

Twenty five F1 (Landrace x Yorkshire) sows parity of 2- 4 were used to determine the effect of catfish fat to late-pregnant and lactating sows on sow and their piglets’ performance. Sows were fed trial diets from 107 d of gestation until 21 d of lactation. Diets were: control without fish fat; 2% fish fat supplementation; 4% fish fat meal supplementation; 6 % fish fat meal supplementation; and 8 % 4% fish fat meal supplementation. The sow’s diet was made from the major ingredients including rice bran, corn meal, cassava meal and soy bean meal. Sows were fed 1.7 kg per day during gestation and 0.25 kg per piglet per day during lactation. Sows were were fed twice a day in the gestation and lactation period with diets containing 14.5 and 17.50 % of CP respectively. Calculated DE concentration in the diets was 13.0 –13.5 MJ per kg. Milk samples were obtained on d 3 and 20 of lactation. Milk from sows fed catfish fat increased n-3 fatty acids on d 3 and 20 of lactation. Results demonstrated that feeding catfish lard has significant effects on sow's milk yield, fatty acid profile and number and weight of weaned piglets

Partial food systems baseline assessment at the Vietnam benchmark sites

Using data collected from a cross-sectional study in Moc Chau, Dong Anh and Cau Giay districts in Vietnam, this report aims to elucidate specific components of local Vietnamese food systems along a rural to urban transect focusing specifically on (i) diets, (ii) nutrition status (anthropometry), (iii) consumer behavior, (iv) food environment, and (v) food flows
