I consider theories of gravity built not just from the metric and affine connection, but also other symmetric tensor. The Lagrangian densities are scalars built from them, and the volume forms are related to Cayley’s hyperdeterminants. The resulting diff-invariant actions give rise to geometric theories that go beyond the metric paradigm, and contain Einstein gravity as a special case. Examples contain theories with generalizeations of Riemannian geometry. The 0-tensor case is related to dilaton gravity. These theories can give rise to (...) new types of spontaneous Lorentz breaking and might be relevant for “dark” sector cosmology. (shrink)

Communication is central to leadership and determines how organizations function and how employees are motivated. Therefore, this research paper aims at comparing English language ability, and management skills, and other elements of leadership. This paper undertakes a qualitative approach wherein the authors review literature and numerous case studies from diverse industries to explore the role of English language proficiency in facilitating leaders to articulate a vision, mobilise people and get things done. At the same time, the paper considers how different (...) managerial approaches, including transformational and transactional leadership, depend on communication to be executed. High English language proficiency improves the message clarity and interpersonal communication, but it is the ability to find and implement effective management approaches that promotes creativity, teamwork, and effectiveness when working in a global environment. The present study demonstrates the co-dependency of language skills and strategic management for the accomplishment of organizational goals and aims. (shrink)
