Utilising feed effectors and automated feeders for semi‐intensive pacific white shrimp (Litopenaeus vannamei) production

open access: yesAquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 540-551, December 2022., 2022
Abstract Feed effectors have been suggested to improve the efficiency of plant‐based shrimp diets by increasing attractability and palatability. This research trial aimed to expand upon previous Pacific white shrimp (Litopenaeus vannamei) research involving plant‐based diets, feed effectors and passive acoustic monitoring (PAM) in a laboratory setting ...

Asset Prices and Asset Quantities [PDF]

open access: yesJournal of the European Economic Association, 2007
We propose an organizing framework that determines asset prices by equating household sector asset demand derived from an economic model to the observed supply of assets provided by other sectors. We then use a specific model of household asset demand to decompose historical changes in asset positions into changes in new asset supply and household ...

Do smaller chicken farms use more antibiotics? Evidence of antibiotic diffusion from Nigeria

open access: yesAgribusiness, Volume 39, Issue 1, Page 242-262, Winter 2023., 2023
Abstract Farmers across the world have been using antibiotics in poultry production for both therapeutic and nontherapeutic purposes since the mid 1900s. The literature on antibiotic diffusion and intensification is largely focused on developed countries in North America and Western Europe.

Risk, uncertainty, and asset prices [PDF]

open access: yesJournal of Financial Economics, 2005
We identify the relative importance of changes in the conditional variance of fundamentals (which we call 'uncertainty') and changes in risk aversion ('risk' for short) in the determination of the term structure, equity prices, and risk premiums.

Comparing Asset Pricing Factor Models under Multivariate t-Distribution: Evidence from China

open access: yesDiscrete Dynamics in Nature and Society, 2021
Factor models provide a cornerstone for understanding financial asset pricing; however, research on China’s stock market risk premia is still limited.

Approximate Equilibrium Asset Prices* [PDF]

open access: yesReview of Finance, 2010
Arguing that total consumer wealth is unobservable, we invert the (approximate) consumption function to reconstruct, in a world with Kreps-Porteus generalized isoelastic preferences, i) the wealth that supports the agents’ observed consumption as an optimal outcome and ii) the rate of return on the consumers’ wealth portfolio.

Forecasting Trends with Asset Prices [PDF]

open access: yesSSRN Electronic Journal, 2015
In this paper, we consider a stochastic asset price model where the trend is an unobservable Ornstein Uhlenbeck process. We first review some classical results from Kalman filtering. Expectedly, the choice of the parameters is crucial to put it into practice.

Regulating Asset Price Risk [PDF]

open access: yesSSRN Electronic Journal, 2011
There has been a long debate about whether speculators are stabilizing or not. We consider a model where speculators have a stabilizing role in normal times, but may also provoke large risk panics. The very feature that makes arbitrageurs liquidity providers in normal times, namely their tolerance of risk, enables a large increase in asset price risk ...

Modelling of a double‐scattering proton therapy nozzle using the FLUKA Monte Carlo code and analysis of linear energy transfer in patients treated for prostate cancer

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The dose‐averaged linear energy transfer (LETD) in proton therapy (PT) has in pre‐clinical studies been linked to the relative biological effectiveness (RBE) of protons. Until recently, the most common PT delivery method in prostate cancer has been double‐scattered PT, with LETD only available through dedicated Monte Carlo (MC ...

Experimental Research on Asset Pricing [PDF]

open access: yesSSRN Electronic Journal, 2013
AbstractThis paper discusses some of the literature on asset market behavior. We do not intend this paper to be an exhaustive survey, but rather a review of some of the more influential results and to illustrate to the nonspecialist reader the diversity of topics that have been pursued.
