Abstract Following the death on April 19, 2015 of Freddie Gray from injuries sustained while unarmed and in police custody, many citizens of Baltimore took to the streets and the National Guard was called into the city. A 2017 article published in the American Journal of Public Health measured the effect of this civil unrest on maternal and child health. I argue that this research does not acknowledge the full range of motivations, behaviors, aims and values that may have been inherent in this unrest. I first describe the article’s characterization of Baltimore’s unrest as community violence. I then provide a negative argument against employing this characterization alone, before providing positive arguments for two alternative characterizations—as protest and apt anger. Finally, I discuss upshots of considering these alternatives. Broadly, while viewing civil unrest as community violence focuses exclusive attention on victims of unrest, these alternatives direct attention to unrest participants, with implications for public health research and practice. While I focus on Baltimore’s 2015 unrest, the proposals raised here apply wherever civil unrest occurs.

Abstract We discuss opportunities in applying the resource-rationality framework toward answering questions in emotion and mental health research. These opportunities rely on characterization of individual differences in cognitive strategies; an endeavor that may be at odds with the normative approach outlined in the target article. We consider ways individual differences might enter the framework and the translational opportunities offered by each.

Community collaboration in research may lead to better methods, results, and dissemination of interventions. Little systematic research has examined specific factors that influence community-based organizations (CBOs) to collaborate in public health research. There is an urgent need to advance knowledge on this topic so that together, researchers and CBOs can minimize barriers to collaboration. This study advances a CBOfocused characterization of collaboration in HIV-prevention research. By focusing on the perspectives of 20 key informants in 10 HIV-prevention CBOs, qualitative data revealed factors that influenced their collaborations in four domains: (a) Researchers’ Characteristics (expertise, availability), (b) Collaborative Research Characteristics (ought to improve services and CBO infrastructure); (c) Community Partner—Researcher Relationships (resolving social and professional issues); and (d) Barriers to HIV-Prevention Research Collaboration (cultural and social disconnect between CBO and academia). To reduce barriers, researchers ought to enhance motivators that facilitate collaboration. To use the advantages of community-based research, prevention scientists and policy makers ought to embrace CBOs’ characterization of what makes health research genuinely collaborative.

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.

Amorphous materials are of current interest due to their desirable mechanical, electrical and magnetic properties. Furthermore, crystallizing amorphous alloys provides an avenue for discerning sequential and competitive phases thus allowing access to otherwise inaccessible crystalline structures. Previous studies have shown the benefits of using AEM to determine crystal structures and compositions of partially crystallized alloys. The present paper will discuss the AEM characterization of crystallized Cu-Ti and Ni-Ti amorphous films.Cu60Ti40: The amorphous alloy Cu60Ti40, when continuously heated, forms a simple intermediate, macrocrystalline phase which then transforms to the ordered, equilibrium Cu3Ti2 phase. However, contrary to what one would expect from kinetic considerations, isothermal annealing below the isochronal crystallization temperature results in direct nucleation and growth of Cu3Ti2 from the amorphous matrix.

A nickel-base superalloy is essentially a Ni/Cr solid solution hardened by additions of Al (Ti, Nb, etc.) to precipitate a coherent, ordered phase. In most commercial alloy systems, e.g. B-1900, IN-100 and Mar-M200, the stable precipitate is Ni3 (Al,Ti) γ′, with an LI2structure. In A lloy 901 the normal precipitate is metastable Nis Ti3 γ′ ; the stable phase is a hexagonal Do2 4 structure. In Alloy 718 the strengthening precipitate is metastable γ″, which has a body-centered tetragonal D022 structure.Precipitate MorphologyIn most systems the ordered γ′ phase forms by a continuous precipitation re-action, which gives rise to a uniform intragranular dispersion of precipitate particles. For zero γ/γ′ misfit, the γ′ precipitates assume a spheroidal.
