Industry Portfolio Volatility Connections and Industry Portfolio Returns
International Journal of Finance &Economics, EarlyView.ABSTRACT This paper tracks dynamic connections that form among daily US industry portfolio return volatilities using a Bayesian time‐varying parameter VAR model. Market participants often focus on sectors to filter vast amounts of information, and this focus results in cross‐industry return predictability. We characterise connections that form over the

Membership‐Making in Diverse Societies: Revisiting the Idea of Society as a Common Possession
Journal of Applied Philosophy, EarlyView.ABSTRACT The traditional aim of Western social democracy has been to create a society that is a ‘common possession’ of its members (in T.H. Marshall's words). Social democratic politics has therefore been both society‐making and membership‐making, orienting people to a shared society as an object of attachment and loyalty, and nurturing membership ...

The Journal of Wildlife Management, EarlyView.We used a population viability analysis to evaluate the influence of headstarting on recovery of the Rouge National Urban Park Blanding's turtle population. Completing the remaining 12 years of the 20‐year headstarting program is projected to approximately double population size relative to no further supplementation.

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.
