What does it mean to find the Face of the Franchise? Physical Attractiveness and the Evaluation of Athletic Performance
Previous research has shown how more attractive people reap more rewards in a variety of settings. We show that attractiveness as measured by facial symmetry leads to greater rewards in professional sports. National Football League quarterbacks who are more attractive are paid greater salaries and this premium persists after controlling for player performance.
How much measurement independence is needed in order to demonstrate nonlocality?
If nonlocality is to be inferred from a violation of Bell's inequality, an
important assumption is that the measurement settings are freely chosen by the
observers, or alternatively, that they are random and uncorrelated with the
hypothetical local variables. We study the case where this assumption is
weakened, so that measurement settings and local variables are at least
partially correlated. As we show, there is a connection between this type of
model and models which reproduce nonlocal correlations by allowing classical
communication between the distant parties, and a connection with models that
exploit the detection loophole. We show that even if Bob's choices are
completely independent, all correlations obtained from projective measurements
on a singlet can be reproduced, with the correlation (measured by mutual
information) between Alice's choice and local variables less than or equal to a
single bit.Comment: 5 pages, 1 figure. v2 Various improvements in presentation. Results

The local content of all pure two-qubit states
The (non-)local content in the sense of Elitzur, Popescu, and Rohrlich (EPR2)
[Phys. Lett. A 162, 25 (1992)] is a natural measure for the (non-)locality of
quantum states. Its computation is in general difficult, even in low
dimensions, and is one of the few open questions about pure two-qubit states.
We present a complete solution to this long-lasting problem.Comment: 9 pages, 3 figure
Being more honest but not necessarily more intelligent than others: Generality and explanations for the Muhammed Ali effect
Two questionnaire studies were conducted ({N} = 80 and {N} = 175) ti examine the structure and the social anchoring of the organizing principles of personal and governmental involvement concerning human rights. The results indicated that these organizing principles had, as hypothesized one abstract and one applied dimension. The second study evaluated the correlations between these dimensions and values. Results were consistent with Schwartz's (1992) model predicting both the internal structure of values and their relations with other variables. Amongst other results, self-transcendence values were positively correlated with the abstract involvements and the applied personal involvement, and negatively with the applied governmental involvement. The results concerning the links between different levels of social anchorings, particularly between the value types and variables such as religious affiliation and practice political preferences, and social and political activism were also presented and discussed
Preservation, Regulations, and Policy to Protect and Grow Baltimore’s Forests
Organizations and city agencies in Baltimore, MD are working together to better protect forests and trees through a combination of preservation efforts, policies, and regulations. Non-profit Baltimore Green Space (BGS), Baltimore’s Department of Recreation and Parks (BCRP), and Baltimore’s Office of Sustainability (BOS) have played major roles in this work. To further advance these efforts, a process is underway to propose new regulations that would better protect and mitigate impacts of development on trees and forested natural areas
