THE BRIDGE WEB SITE GROWING AND SUSTAINING PARTNERSHIPS BETWEEN OCEAN SCIENCE AND EDUCATION

When physicist Tim Berners-Lee and a team of fellow scientists at the European Center for High Energy Physics (CERN) launched the first-ever Web site in 1989, their goal was to make it easier for scientists to access research documents and scientific data (CERN, 2008). In 1998, Virginia Sea Grant educators at the Virginia Institute of Marine Science (VIMS) had a similar goal: to make ocean science educational resources and current research data more accessible to classroom teachers. The Virginia Sea Grant education team took the first step toward accomplishing this goal by launching a Web site of its own, called "Bridge." The name was inspired by the idea of a ship's bridge with a teacher at the helm, navigating "an ocean of marine education data." It also represents a bridge spanning the divide between the education and the ocean research communities, which is the essence of the Bridge project's mission

Variant supercurrent multiplets

In N = 1 rigid supersymmetric theories, there exist three standard realizations of the supercurrent multiplet corresponding to the (i) old minimal, (ii) new minimal and (iii) non-minimal off-shell formulations for N = 1 supergravity. Recently, Komargodski and Seiberg in arXiv:1002.2228 put forward a new supercurrent and proved its consistency, although in the past it was believed not to exist. In this paper, three new variant supercurrent multiplets are proposed. Implications for supergravity-matter systems are discussed.Comment: 11 pages; V2: minor changes in sect. 3; V3: published version; V4: typos in eq. (2.3) corrected; V5: comments and references adde

Comments on Supercurrent Multiplets, Supersymmetric Field Theories and Supergravity

We analyze various supersymmetry multiplets containing the supercurrent and the energy-momentum tensor. The most widely known such multiplet, the Ferrara-Zumino (FZ) multiplet, is not always well-defined. This can happen once Fayet-Iliopoulos (FI) terms are present or when the Kahler form of the target space is not exact. We present a new multiplet S which always exists. This understanding of the supersymmetry current allows us to obtain new results about the possible IR behavior of supersymmetric theories. Next, we discuss the coupling of rigid supersymmetric theories to supergravity. When the theory has an FZ-multiplet or it has a global R-symmetry the standard formalism can be used. But when this is not the case such simple gauging is impossible. Then, we must gauge the current S. The resulting theory has, in addition to the graviton and the gravitino, another massless chiral superfield Phi which is essential for the consistency of the theory. Some of the moduli of various string models play the role of Phi. Our general considerations, which are based on the consistency of supergravity, show that such moduli cannot be easily lifted thus leading to constraints on gravity/string models.Comment: 27 pages. v2: references added and minor changes. v3: minor changes. v4: minor clarification

An optically stimulated superconducting-like phase in K3C60 far above equilibrium Tc

The control of non-equilibrium phenomena in complex solids is an important research frontier, encompassing new effects like light induced superconductivity. Here, we show that coherent optical excitation of molecular vibrations in the organic conductor K3C60 can induce a non-equilibrium state with the optical properties of a superconductor. A transient gap in the real part of the optical conductivity and a low-frequency divergence of the imaginary part are measured for base temperatures far above equilibrium Tc=20 K. These findings underscore the role of coherent light fields in inducing emergent order.Comment: 40 pages, 23 figure

The Encoding of Temporally Irregular and Regular Visual Patterns in the Human Brain

In the work reported here, we set out to study the neural systems that detect predictable temporal patterns and departures from them. We used functional magnetic resonance imaging (fMRI) to locate activity in the brains of subjects when they viewed temporally regular and irregular patterns produced by letters, numbers, colors and luminance. Activity induced by irregular sequences was located within dorsolateral prefrontal cortex, including an area that was responsive to irregular patterns regardless of the type of visual stimuli producing them. Conversely, temporally regular arrangements resulted in activity in the right frontal lobe (medial frontal gyrus), in the left orbito-frontal cortex and in the left pallidum. The results show that there is an abstractive system in the brain for detecting temporal irregularity, regardless of the source producing it

The 12 Item Social and Economic Conservatism Scale (SECS)

Recent years have seen a surge in psychological research on the relationship between political ideology (particularly conservatism) and cognition, affect, behaviour, and even biology. Despite this flurry of investigation, however, there is as yet no accepted, validated, and widely used multi-item scale of conservatism that is concise, that is modern in its conceptualisation, and that includes both social and economic conservatism subscales. In this paper the 12-Item Social and Economic Conservatism Scale (SECS) is proposed and validated to help fill this gap. The SECS is suggested to be an important and useful tool for researchers working in political psychology

Reputation and identity conflict in management consulting

This is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.Based on a case study of a large consulting firm, this paper makes two contributions to the literature on reputation and identity by examining how an organization responds when its identity is substantially misaligned with the experience and perceptions of external stakeholders that form the basis of reputational judgments. First, rather than triggering some form of identity adaptation, it outlines how other forms of identity can come into play to remediate this gap, buffering the organization’s identity from change. This shift to other individual identities is facilitated by a low organizational identity context even when the identity of the firm is coherent and strong. The second contribution concerns the conceptualization of consulting and other professional service firms. We explain how reputation and identity interact in the context of the distinctive organizational features of these firms. Notably, their loosely coupled structure and the central importance of expert knowledge claims enable individual consultants both to reinforce and supplement corporate reputation via individual identity work

A search for the decay modes B+/- to h+/- tau l

We present a search for the lepton flavor violating decay modes B+/- to h+/- tau l (h= K,pi; l= e,mu) using the BaBar data sample, which corresponds to 472 million BBbar pairs. The search uses events where one B meson is fully reconstructed in one of several hadronic final states. Using the momenta of the reconstructed B, h, and l candidates, we are able to fully determine the tau four-momentum. The resulting tau candidate mass is our main discriminant against combinatorial background. We see no evidence for B+/- to h+/- tau l decays and set a 90% confidence level upper limit on each branching fraction at the level of a few times 10^-5.Comment: 15 pages, 7 figures, submitted to Phys.
