Since Dirac predicted in 1937 the possible variation of gravitational constant and other coupling constants from his large number hypothesis, efforts continue to determine such without success. Such focus on one while assuming all others pegged their currently measured values. We show that variations speed light [Formula: see text], Planck Boltzmann text] are interrelated: text]. Thus, constrai...

The study examined task interdependence as a structural factor, which influences the emergence of collective-efficacy versus self-efficacy as a team level construct. It tested for the differential effects of selfand collective-efficacy on team performance, and the effects of initial perceptions of selfand collective-efficacy and record of past performance on the development of their subsequent ...

In this paper, we examine the scope for international stock portfolio diversification, from the viewpoint of a United States representative investor, in regard to both the Asian and the European stock markets. Our findings indicate that despite correlation style evidence to the contrary, the European stock markets provide a superior long-term diversification opportunity relative to that provide...

OBJECTIVES We studied the impact of globalization on the making of health policy. Globalization is understood as economic interdependence among nations. The North American Free Trade Agreement is used as a marker to assess the effects of economic interdependence on binational health cooperation along the United States-Mexico border. METHODS We observed participants and conducted in-depth inte...

This paper investigates the dynamic evolution of tail risk interdependence among U.S. banks, financial services and insurance sectors. Life and non-life insurers have been considered separately to account for their different characteristics. The tail risk interdependence measurement framework relies on the multivariate Student-t Markov switching (MS) model and the multiple-conditional value-at-...

Extending research based on different-sex (i.e., heterosexual) couples, the authors explored associations between romantic relationship quality and depressive symptoms in a geographically diverse sample (N = 571) of U.S. adults in same-sex relationships. The authors also examined whether this association was moderated by individual characteristics (gender, age, and internalized heterosexism) or...
