A growth model of weight preferences, food consumption and public policy
Copyright @ 2013 Brunel University.In this paper we unify existing theories and empirical evidence on the origins of
obesity and examine the e¤ects of scal policy on the dynamic evolution of weight. We
build a dynamic general equilibrium growth model, with two sectors, one producing
food and the other producing a composite consumption good. Weight is a function of
rational choice as well as labor allocation between the two sectors. By estimating utility
from weight and calibrating the US economy we show that (i) technological advances
in agriculture decrease food prices and increase weight but not necessarily through
higher food consumption but through lower calorie expenditure, (ii) reducing capital
taxation, initially depresses weight levels through higher food prices; steady state food
consumption decreases due to a price substitution e¤ect but weight soars due to lower
calorie expenditure, (iii) reducing taxation on food increases food consumption and
weight levels in equilibrium. Labor reallocation towards the less sedentary sector on
one hand and higher income on the other function as contradictory forces
Distributed lag models for hydrological data
The distributed lag model (DLM), used most prominently in air pollution studies, finds application
wherever the effect of a covariate is delayed and distributed through time. We explore the use of modified formulations
of DLMs to provide flexible varying-coeficient models with smoothness constraints, applicable in any setting in which
lagged covariates are regressed on a time-dependent response. The models are applied to simulated flow and rainfall
data and to flow data from a Scottish mountain river, with particular emphasis on approximating the relationship
between environmental covariates and flow regimes in order to detect the influence of unobserved processes. It was
found that under certain rainfall conditions some of the variability in the influence of rainfall on flow arises through
a complex interaction between antecedent ground wetness and the time-delay in rainfall. The models are able to
identify subtle changes in rainfall response, particularly in the location of peak influence in the lag structure and offer
a computationally attractive approach for fitting DLMs

Persistent, symptomless, systemic, and seed-borne infection of lettuce by Botrytis cinerea
Experiments are presented which show that Botrytis cinerea, the cause of gray mould disease, is often present in symptomless lettuce plants as a systemic, endophytic, infection which may arise from seed. The fungus was isolated on selective media from surface sterilized sections of roots, stem pieces and leaf discs from symptomless plants grown in a conventional glasshouse and in a spore-free air-flow provided by an isolation propagator. The presence of B. cinerea was confirmed by immuno-labelling the tissues with the Botrytis-specific monoclonal antibody BC-12.CA4. As plants grew, infection spread from the roots to stems and leaves. Surface sterilization of seeds reduced the number of infected symptomless plants. Artificial infection of seedlings with dry conidia increased the rate of infection in some experiments. Selected isolates were genetically finger-printed using microsatellite loci. This confirmed systemic spread of the inoculating isolates but showed that other isolates were also present and that single plants hosted multiple isolates. This shows that B. cinerea commonly grows in lettuce plants as an endophyte, as has already been shown for Primula. If true for other hosts, the endophytic phase may be as important a component of the species population as the aggressive necrotrophic phase
Experimental evaluation of shockless supercritical airfoils in cascade
Surface Mach number distributions, total pressure loss coefficients, and schlieren images of the flow are presented over a range of inlet Mach numbers and air angles. Several different trailing edge geometries were tested. At design conditions a leading edge separation bubble was observed resulting in higher losses than anticipated. The minimum losses were obtained at a negative incidence condition in which the flow was accelerating over most of the supercritical region. Relatively minor differences in losses were measured with the different trailing edge geometries studied
