Recent Developments: The Right to a Fair Cross-Section of the Community and the Black Box of Jury Pool Selection in Arkansas

A Washington County, Arkansas court conducted a hearing on October 15, 2018 on a criminal defendant’s motion to compel discovery to assure a fair and accurate cross-section of the community for the jury as guaranteed by the United States and Arkansas Constitutions. At the hearing, the jury coordinator for the Circuit Clerk’s office testified that counties may elect to use a state-sponsored jury selection computer program, or they may use proprietary programs. Washington County uses a proprietary computer program to select the jury pool from a list of registered voters. The clerk described how her office takes an extra step to follow up with property owners, thus making them more likely to be summoned for jury duty. When discussing individuals who cannot afford phone service or who do not have voice mail, she stated, “You can’t talk to them. So I don’t reach that person.” She did not know how individuals with criminal records are excluded from the pool so that individuals with duplicate names – which is common, for example, in the Hispanic community – are not excluded. When asked about her system of calling and leaving messages, she stated she does not have a translator because “I’ve never had anyone talk to me that I couldn’t understand.” Although the United States Supreme Court has noted that “without inspection, a party almost invariably would be unable to determine whether he has a potentially meritorious jury challenge,” the Washington County judge concluded that the details of the process and software used for creating the venire are “not discoverable in this case because. . .you have not presented any evidence you would find anything.

Energy-dependent Lorentz covariant parameterization of the NN interaction between 50 and 200 MeV

For laboratory kinetic energies between 50 and 200 MeV, we focus on generating an energy-dependent Lorentz covariant parameterization of the on-shell nucleon-nucleon (NN) scattering amplitudes in terms of a number of Yukawa-type meson exchanges in first-order Born approximation. This parameterization provides a good description of NN scattering observables in the energy range of interest, and can also be extrapolated to energies between 40 and 300 MeV.Comment: 18 pages, 7 figures, Final version accepted by Physics Review

Sensitivity of neutron radii in the ""sup208Pbnucleusandaneutronstartonucleon−"" sup 208_Pb nucleus and a neutron star to nucleon- sigma_-$ rho_ coupling corrections in relativistic mean field theory

We study the sensitivity of the neutron skin thickness, $S$, in a $^{208}$Pb nucleus to the addition of nucleon-sigma-rho coupling corrections to a selection (PK1, NL3, S271, Z271) of interactions in relativistic mean field model. The PK1 and NL3 effective interactions lead to a minimum value of $S$ = 0.16 fm in comparison with the original value of $S$ = 0.28 fm. The S271 and Z271 effective interactions yield even smaller values of $S$ = 0.11 fm, which are similar to those for nonrelativistic mean field models. A precise measurement of the neutron radius, and therefore $S$, in $^{208}$Pb will place an important constraint on both relativistic and nonrelativistic mean field models. We also study the correlation between the radius of a 1.4 solar-mass neutron star and $S$.Comment: 40 pages 13 figures. to be published in Physical Review

Patients’ Perspective of Patient-Centered Approach vs. Biomedical Approach

Evidence-based practice in audiology may consist of a patient-centered approach or a biomedical approach when offering individuals the results of hearing evaluations. Boisvert et al. (2017) and the Institute for Defense Analysis confirmed that audiologists preferred to select one approach. The question was if an audiology patient is presented with two options of explaining the hearing health issues, which model/approach will be his or her preference? Participants may have had unconscious biases related to race or gender that could have unknowingly impacted their perception of the videos. The results of this research will facilitate clinical understanding of individual preferences regarding hearing aid recommendations, leading to improved health outcomes. The author addressed the decisions patients and doctors may encounter specific to chosen approaches for interpreting hearing diagnostics to individuals. The question of preferred approaches for both patients and audiologists to hearing health care recommendations is emerging in the literature, and this study continues to address the preferences. Clinical implications, limitations, and future research needs were also discussed

Review of \u3ci\u3eThe Tallgrass Prairie Center Guide to Seed and Seedling Identification in the Upper Midwest. \u3c/i\u3eBy Dave Williams.

This book will please both practitioners of prairie restoration and more general prairie enthusiasts. It includes 72 grass and forb species, and the focus is clearly on species often found in tallgrass prairie plantings in the upper Midwest. The grasses and forbs are presented separately here, and for each group a morphological key is provided to divide the species into Key Characteristic Groups. Because these groups are based on morphological similarity, species within a group are often-but not always-closely related. Short and highly portable, the book covers the most common species in plantings. The only thing that would have delighted me more would have been having this type of information on even more species. Overall, this is an excellent resource, and one I look forward to using often

Transfer function of the modified Kramer system

The use of operational mathematics in the solution of engineering problems has grown tremendously in the last two decades, particularly during the last war. This has come about because of the facility with which problems which would be almost impossibly complicated or tedious to solve by classical methods can be solved using operational calculus. The operational calculus, particularly the Laplace transform method, has become especially useful in the field of servomechanisms and controls. Here the constantly increasing complexity of systems used has resulted in very high order differential equations. The fact that the Laplace transform method makes it possible to inject the boundary conditions into the initial equations is often a great advantage in their solution. In addition, the fact that much can often be learned about the behavior of a system by a study of its operational equations, without having to resort to an actual solution, makes this approach even more valuable. This paper proposes to develop the complete operational solution, or transfer function, of a specific control system, namely, the modified Kramer system for speed control of induction motors. This transfer function is derived as a basis for further study of the performance of the system, or of its components --Introduction, page 1
