Electroweak baryogenesis in a single Higgs doublet model is considered. A renormalization group-improved effective potential is used. The requirement that the created baryon asymmetry is not washed out leads to bounds on the Higgs mass which vary significantly with the top quark mass.

The objective of this paper is to investigate the short run as well as long run relationship between GDP, exports and imports for India using annual data from 1982 to 2016. Through this paper, I examine the four main hypotheses regarding the relation between exports, imports and economic growth. The first one is export-led growth hypothesis, the second one is the import-led growth hypothesis, the third one is the growth-led exports and lastly, the growth-led imports hypothesis. The Johansen’s cointegration is used to examine the long term relationship and empirical results indicate that there is a long run relationship between GDP, exports and imports. The short term relationship is measured using the Granger causality test and the statistical results suggest unidirectional causality from GDP to exports and GDP to imports in conformity with the growth-led exports and growth-led imports hypothesis respectively.

Interlocus sexual conflict (ISC) arises due to antagonistic interactions between the sexes. Recent evidence suggests that the intensity of ISC could reduce due to habitat complexity and spatial structure, especially if it results in reduced encounter rate between sexes. Hence, spatial structuring, a common attribute of most natural populations, can potentially bring down the intensity of ISC. We tested this theory using laboratory populations of Drosophila melanogaster. We set up cohorts in three-patch habitat systems as either interconnected (structured) or unconnected (unstructured). Following a fully crossed design, we measured ISC by comparing reproductive output and starvation resistance of singly mated females and those continuously housed with surplus males. We show that continued exposure to males leads to significant fitness costs, indicating ISC. The experimental habitat type did not affect ISC. However, we found significant reproductive and survival costs arising from structured population. Our results are also robust to the alteration in female condition. Therefore, it appears that spatial structure per se cannot decrease ISC, but impose additional survival costs. We further showed such survival cost to be sex-specific, possibly reflecting female-biased spontaneous dispersal.
