A Global Analysis of Electroweak Data (including Fermion Masses and Mixing Angles) in SO(10) SUSY GUTs
We present a global analysis of electroweak data, including fermion
masses and mixing angles, in SO(10) SUSY GUTs. Just as precision electroweak
data is used to test the Standard Model, the well determined Standard Model
parameters are the precision electroweak data for testing theories beyond the
Standard Model. In this talk we use the latest experimentally measured values
for these parameters. We study several models discussed in the literature. One
of these models provides an excellent fit to the low energy data with for 3 degrees of freedom. We present our predictions for a few selected
points in parameter space.Comment: 8 pages, LateX type, talk presented by S. Raby at the Fourth

The impact of SARS-CoV-2 in dementia across Latin America : A call for an urgent regional plan and coordinated response
The SARS-CoV-2 global pandemic will disproportionately impact countries with weak economies and vulnerable populations including people with dementia. Latin American and Caribbean countries (LACs) are burdened with unstable economic development, fragile health systems, massive economic disparities, and a high prevalence of dementia. Here, we underscore the selective impact of SARS-CoV-2 on dementia among LACs, the specific strain on health systems devoted to dementia, and the subsequent effect of increasing inequalities among those with dementia in the region. Implementation of best practices for mitigation and containment faces particularly steep challenges in LACs. Based upon our consideration of these issues, we urgently call for a coordinated action plan, including the development of inexpensive mass testing and multilevel regional coordination for dementia care and related actions. Brain health diplomacy should lead to a shared and escalated response across the region, coordinating leadership, and triangulation between governments and international multilateral networks
A Global chi^2 Analysis of Electroweak Data in SO(10) SUSY GUTs
We present the details of a global analysis of electroweak data,
including fermion masses and mixing angles, in SO(10) SUSY GUTs. Just as
precision electroweak data is used to test the Standard Model, the well
determined Standard Model parameters are the precision electroweak data for
testing theories beyond the Standard Model. In this paper we use the latest
experimentally measured values for these parameters. We study several models
discussed in the literature. One of these models provides an excellent fit to
the low energy data with for 3 degrees of freedom. We present
graphs of constant contours as functions of position in soft SUSY
breaking parameter space, as well as our predictions for a few selected points
in parameter space. We also study the sensitivity of our results to changes in
various parameters. Finally, we discuss the consequences of our work in the
context of a general MSSM analysis at the Z scale.Comment: 37 pages, Latex, 14 figures included in separate file

Competition and Prosociality: A Field Experiment in Ghana
Competitive bonuses are commonly used to promote higher productivity in the workplace. Yet, these types of incentives could have negative spillovers on coworkers' prosocial behavior in subsequent tasks. To investigate this question, we conduct a lab-in-the-eld experiment in Ghana. In a between-subjects design, participants complete a real-eort task under a competitive, threshold, or random payment while holding payment dierentials constant across treatments. Before and after, we measure prosociality through a public goods and a social value orientation game. Competition reduces prosociality when the dispersion of payments is high. However, when there is less at stake, competition does not aect prosociality
