Noether-Wald Charges in Critical Gravity
Indexación: Scopus.Critical Gravity theory is defined by a particular combination of quadratic couplings in the curvature added on top of 4D Einstein-Hilbert action with negative cosmological constant. As the Lagrangian is given by a Weyl-squared term, the asymptotic form of the curvature is not modified. The coupling of the W eyl 2 term is such the massive scalar mode is eliminated and the massive spin-2 mode become massless, rendering the theory consistent around the critical point. In the present work, we construct the Noether-Wald charges for the action of Critical Gravity. Such construction makes manifest a defining property of this theory: both the energy and entropy for Einstein black holes vanish identically. © Published under licence by IOP Publishing Ltd.We thank G.

The attitudes of Puerto Ricans toward the participation of women in the labor force of the island.
This study reviews historical current factors limiting Puerto Rican women in the area of educational preparation and in the island\u27s work force. Attitudes are identified in Puerto Rican society as well as reactions to the increasing role of women in the island\u27s work force. Three questions guided this study. (1) Is there evidence in the history of Puerto Rico indicating discrimination of women at work? (2) Have educational opportunities promoted or limited the participation of women in the island\u27s labor force? (3) Are Puerto Ricans\u27 attitudes obstacles deterring women from entry into occupations or professions traditionally male dominated? An instrument designed, tested and applied randomly on a cross section of voters in Jayuya and in Precinct Two of San Juan, provided a 68.66% return. After a careful analysis of the findings of the study the following conclusions could be made. (1) There is clear evidence in the history of Puerto Rico indicating discrimination towards women in the work place. This is evident in a perusal of the island\u27s political, economic, social and educational history. An analysis of data gathered by governmental agencies and findings of studies done by private and public work places show a limited number of higher management positions held by women. Prevalent discrimination is evident by the need to pass laws to protect the rights of women and to eliminate gender bias in the work place. The low representation of women in administrative positions as well as in legislative, judicial and other jobs in government, have further limited professional growth for women. (2) Even when educational opportunities for women have advanced their participation in the labor force, they have served to limit their participation in the work force by leading them into jobs and professions that are extensions of traditional roles. (3) Beliefs persist that minimize the capabilities and potentials of women, creating low expectations of their contributions to the labor force. This attitude plays a negative role in educational practices resulting in additional discrimination against women in Puerto Rico
Energy in higher-derivative gravity via topological regularization
Indexación: Scopus.We give a novel definition of gravitational energy for an arbitrary theory of gravity including quadratic-curvature corrections to Einstein's equations. We focus on the theory in four dimensions, in the presence of a negative cosmological constant, and with asymptotically anti-de Sitter (AdS) boundary conditions. As a first example, we compute the gravitational energy and angular momentum of Schwarzschild-AdS black holes, for which we obtain results consistent with previous computations performed using different methods. However, our method is qualitatively different due to the fact that it is intrinsically nonlinear. It relies on the idea of adding to the gravity action topological invariant terms which suffice to regularize the Noether charges and render the variational problem well-posed. This is an idea that has been previously considered in the case of second-order theories, such as general relativity and which, as shown here, extends to higher-derivative theories. Besides black holes, we consider other solutions such as gravitational waves in AdS, for which we also find results that are in agreement. This enables us to investigate the consistency of this approach in the non-Einstein sector of the theory. © 2018 authors.
