Contrary to previous empirical studies that find a linear link between economic conditions and presidential approval, this study argues for and finds a nonlinear relationship. A threshold regression is used to assess potential nonlinear relationships between macroeconomic variables and presidential popularity. A quarterly data analysis for the 1960Q1–2012Q2 time period reveals that domestic fac...

Microfinance is gathering momentum to become a major force in India. The self-help group (SHG) model with bank lending to groups of (often) poor women without collateral has become an accepted part of rural finance. The paper discusses the state of SHG-based microfinance in India. With traditionally loss-making rural banks shifting their portfolio away from the rural poor in the post-reform per...

in order to evaluate the response of emergence rate of oil seed rape seedlings to temperature, a pot experiment was conducted to assess the relationship between emergence rate of three rape seed cultivars (apetalous flower, rgs003 and syn3) by using a non-linear regression against temperature variation. six models (tooth shape, segmented, beta, curve, quadratic and cubic) were used and the supe...

the ultimate goal of power system operation and planning is to increase power system reliability which enforces interconnected operation of power system. as a result of power system interconnection, the inter-area oscillation under different disturbances may cause power system partial or total blackout. dc-segmentation of interconnected power systems is a solution in which the topology of the n...

We measured the polarized and azimuthal dependencies of optical second harmonics generation (SHG) on polished surfaces of ZnSe(100) single crystal surface in air, using a fundamental wavelength of 1.06μm. By considering both, the bulkand surfaceoptical nonlinearities within the electric dipole approximation, we analysed the data for all four combination of pand s-polarized incidence and output....
