The role of chemical cues in the host finding behaviour of Trissolcus basalis from a Conservation Biological Control perspective

In assessing successful biological control programs by parasitoids, the knowledge of important traits, such as the host finding capability, i.e. the ability to find host and food resources, play the key role. Moreover, parasitoids in their natural environment parasitoids deal with a variable mixtures of natural cues. Some chemical cues are used by the wasps to locate their hosts, some ones drive wasps to feeding resources. The parasitoid response to these cues can fluctuate according to biotic factors and abiotic condition. This dissertation focus in details on the role of two important tools, such as selective flowering plants as food resources to add within a crop area and the traces left…

Forecast Output Coincidence and Biproportion: Two Criteria to Determine the Orientation of an Economy. Comparison for France (1980-1997)

2002

International audience; The method of forecast output coincidence used to determine if sectors are demand-sided or supply-sided in an input-output framework mixes two effects, the structural effect (choosing between demand and supply side models) and the effect of an exogenous factor (final demand or added-value). The note recalls that another method is possible, the comparison of the stability of technical and allocation coefficients, generalized by the biproportional filter: if for a sector, after biproportional filtering, column coefficients are more stable than row coefficients, then this sector is declared as not supply-sided (but one cannot decide that it is demand-sided anyway), and …

The Influence of the Endogenous and Exogenous Factors on Credit Institutions’ Return on Equity

2015

Abstract The research’s purpose is to study the credit institutions’ performance, from the shareholders’ point of view, through return on equity (ROE). It aims to identify a dependency relationship between return on equity (ROE) and endogenous factors (the growth rate of credit portfolio, the growth rate provisions, the solvency ratio), on the one hand and, on the other hand between ROE and the exogenous ones (GDP and inflation rate). The research was done over an horizon of 10 years (2004-2013) on the evolution of the return on equity indicator of two credit institutions listed on Bucharest Stock Exchange (Carpathian Commercial Bank SA and Banca Transilvania SA), highlights their vulnerabi…
