Scaffolds and Generalized Integral Galois Module Structure
Let be a finite, totally ramified -extension of complete local
fields with residue fields of characteristic , and let be a
-algebra acting on . We define the concept of an -scaffold on ,
thereby extending and refining the notion of a Galois scaffold considered in
several previous papers, where was Galois and for
. When a suitable -scaffold exists, we show how to
answer questions generalizing those of classical integral Galois module theory.
We give a necessary and sufficient condition, involving only numerical
parameters, for a given fractional ideal to be free over its associated order
in . We also show how to determine the number of generators required when it
is not free, along with the embedding dimension of the associated order. In the
Galois case, the numerical parameters are the ramification breaks associated
with . We apply these results to biquadratic Galois extensions in
characteristic 2, and to totally and weakly ramified Galois -extensions in
characteristic . We also apply our results to the non-classical situation
where is a finite primitive purely inseparable extension of arbitrary
exponent that is acted on, via a higher derivation (but in many different
ways), by the divided power -Hopf algebra.Comment: Further minor corrections and improvements to exposition. Reference

A Human Capital Approach to Reduce Health Disparities
Objective: To introduce a human capital approach to reduce health disparities in South Carolina by increasing the number and quality of trained minority professionals in public health practice and research.
Methods: The conceptual basis and elements of Project EXPORT in South Carolina are described. Project EXPORT is a community based participatory research (CBPR) translational project designed to build human capital in public health practice and research. This project involves Claflin University (CU), a Historically Black College University (HBCU) and the African American community of Orangeburg, South Carolina to reduce health disparities, utilizing resources from the University of South Carolina (USC), a level 1 research institution to build expertise at a minority serving institution. The elements of Project EXPORT were created to advance the science base of disparities reduction, increase trained minority researchers, and engage the African American community at all stages of research.
Conclusion: Building upon past collaborations between HBCU’s in South Carolina and USC, this project holds promise for a public health human capital approach to reduce health disparities
Diffusive Atomistic Dynamics of Edge Dislocations in Two Dimensions
The fundamental dislocation processes of glide, climb, and annihilation are
studied on diffusive time scales within the framework of a continuum field
theory, the Phase Field Crystals (PFC) model. Glide and climb are examined for
single edge dislocations subjected to shear and compressive strain,
respectively, in a two dimensional hexagonal lattice. It is shown that the
natural features of these processes are reproduced without any explicit
consideration of elasticity theory or ad hoc construction of microscopic
Peierls potentials. Particular attention is paid to the Peierls barrier for
dislocation glide/climb and the ensuing dynamic behavior as functions of strain
rate, temperature, and dislocation density. It is shown that the dynamics are
accurately described by simple viscous motion equations for an overdamped point
mass, where the dislocation mobility is the only adjustable parameter. The
critical distance for the annihilation of two edge dislocations as a function
of separation angle is also presented.Comment: 13 pages with 17 figures, submitted to Physical Review
Non-contracting groups generated by (3,2)-automata
© Journal Algebra and Discrete Mathematics. We add to the classification of groups generated by 3-state automata over a 2-letter alphabet given by Bondarenko et al., by showing that a number of the groups in the classification are non-contracting. We show that the criterion we use to prove a self-similar action is non-contracting also implies that the associated self-similarity graph introduced by Nekrashevych is non-hyperbolic
ABET Accreditation of IS and IT Programs in 2013
The Accreditation Board for Engineering and Technology (ABET) has been accrediting engineering and computer science for many years. In recent years ABET has been accrediting Information Systems and Information Technology programs. ABET first accredited IS in 2000 and IT in 2003. ABET appears to have become the standard accreditation for IT and in the spring of 2014 there are 25 IT programs accredited by ABET. There are 38 IS programs accredited by ABET since 2000. This paper looks at the IS and IT ABET accredited programs and examines the common features and differences of these related accredited programs
Examination of Racial Disparities in Childhood Asthma Management Practices
Objective: To analyze asthma management plan practices for children with asthma in the United States considering race and other demographic and person-level characteristics.
Methods: Univariate/Bivariate/Multivariate analysis was performed to examine asthma management plan physician recommendations among children in the United States utilizing secondary data analysis of the 2002 and 2003 National Health Interview Survey.
Results: The majority of the study participants reported not having an asthma management plan at (59.00%). In multivariate analysis using SAS callable SUDAAN, Whites were significantly more likely to have an asthma management plan (OR=1.66, p=.0031).
Conclusion: Findings from this study indicate that Black and Hispanic children with asthma are less likely to have an asthma management plan. Mandating all insurers to provide an asthma management plan to children with asthma may reduce the race-based inequities and requiring emergency room physicians to provide children with an asthma management plan may target those children that do not have a plan
Glassy phases and driven response of the phase-field-crystal model with random pinning
We study the structural correlations and the nonlinear response to a driving
force of a two-dimensional phase-field-crystal model with random pinning. The
model provides an effective continuous description of lattice systems in the
presence of disordered external pinning centers, allowing for both elastic and
plastic deformations. We find that the phase-field crystal with disorder
assumes an amorphous glassy ground state, with only short-ranged positional and
orientational correlations even in the limit of weak disorder. Under increasing
driving force, the pinned amorphous-glass phase evolves into a moving
plastic-flow phase and then finally a moving smectic phase. The transverse
response of the moving smectic phase shows a vanishing transverse critical
force for increasing system sizes
Gender gaps in the path to adulthood for young females and males in six African countries from the 1990s to the 2010s
In this paper, we study on a comparative basis the school-to-work transition of young women and young men in six countries in sub-Saharan Africa, and we examine how this has evolved over recent years, based on the data collected by Demographic and Health Surveys. We examine educational attainments and the nature of early jobs young people are able to obtain, as well as considering their relationship to marriage and fertility outcomes, factors which are likely to be particularly relevant for young women. A pooled regression analysis shows that educational levels have increased substantially and gender gaps have narrowed in most countries. Access to better jobs has improved much more slowly with unchanging gender gaps in most countries, so that agriculture is still the dominant sector of employment for most young men and women. We model correlates of key educational outcomes and access to different types of jobs those controlling for individual- and household-level characteristics, including marital status, presence of children and wealth. Attaining a high level of education is unsurprisingly critical for access to the best jobs and is also associated with young women delaying marriage and childbearing
