Application of a bioenergetic growth model to larvae of the pearl oyster Pinctada margaritifera L.
Provedor de dados: 5
Autores: Thomas, Yoann; Garen, Pierre; Pouvreau, Stephane.
We applied, for the first time, a dynamic energy budget (DEB) growth model to the larval phase in the pearl oyster Pinctada margaritifera var. cumingii (Linnaeus, 1758) to evaluate the impact of spatio-temporal variation in the atoll lagoon environment on its capacity for development. The specific parameters of the model, which represent ingestion, temperature effect and the relationship between length and biovolume of the larvae, were determined from experiments or taken from the literature. The interpretation of the values of these parameters allowed us to identify the underlying adaptive character trait: P. margaritifera larvae have a good capacity to exploit low food concentrations and a narrow range of thermal tolerance restricted to hydrobiological...

Experiments were performed on juvenile sole in controlled conditions in the aim of understanding how the biology of common sole may affect the accumulation and dilution of Polychlorinated biphenyls (PCBs). The fish were raised in optimal conditions and divided into two tanks: one control tank and one PCB tank. 4 PCB congeners were added to food for 3 months in the PCB tank; the soles were subsequently fed unspiked food for 3 months. Growth (length and weight) and PCB concentrations were monitored in both tanks and juvenile sole growth was not significantly affected by PCBs in our experimental conditions. We used the Dynamic Energy Budget (DEB) theory to model sole biology and paid special attention to model calibration through the wide use of data from the...

Analyzing Growth and Welfare Effects of Public Policies in Models of Endogenous Growth with Human Capital: Evidence from South Africa
Provedor de dados: 31
Autores: Badibanga,   Thaddee Mutumba.
Since the abolition of its Apartheid regime in 1994, South Africa has launched a massive program of education, which has been financed through resources representing on average 21% of the national budget or 7% of GDP. Today, the GDP share of public spending on education is 1.3 times the average of industrialized countries (5.4%) and almost twice that of developing countries (3.9%). In this paper, we simulate fiscal policy experiments to analyze the growth and welfare effects of a shift in the allocation of government expenditures between public spending on education and transfers as well as those of a change in the tax rate in a model of endogenous growth with human capital accumulation for the South African economy. The results of simulations demonstrate...
