In this paper we show that, under the assumption that all the zeros of the L-functions under consideration are either real or lie on the critical line, one may considerably improve on the known results on Landau-Siegel zeros.

This paper aims to assess the possibility of predicting Croatian recessionary episodes using probit models. The authors first estimate a baseline static model using four leading indicators of recession (monetary base, unemployment, industrial production, and CROBEX stock market index). Lag lengths of up to 6 months are examined for each of the observed variables in the probit specification, and...

Based on epidemiological observations Barker et al. put forward the hypothesis/concept that an adverse intrauterine environment (involving insufficient nutrient supply, chronic hypoxia, stress, and toxic substances) is important risk factor for development of diseases later in life. The fetus responds to unfavorable with adaptive reactions, which ensure survival short run, but at expense initia...

In 1987, David Cairns proposed that a gradient of colony-based measures on seabirds could be used to assess food supply in the ocean. Measures closely tied to the ocean, such as foraging trip duration, would be sensitive to small declines in food supply while measures more closely tied with the nest site, such as reproductive success, would be sensitive to large declines in food supply. The con...

Abstract Spatial variations in light and nutrient availability usually lead to a heterogeneous distribution of periphyton biomass within streams, but the effects enrichment on heterogeneity are still poorly understood. We tested phosphorus quantity nutritional quality an environment with uneven conditions. Natural was grown at either high or low P supply circular running water flumes, each whic...

in today’s complex, dynamic and ever changing modern environment, all companies need to design and use strategies helping them to improve continuous performance, because in such a competitive environment, those companies which keep pace with changing and dynamic conditions of competitive market are able to survive. this study was conducted using descriptive – correlational methodology. the stud...
