Collusion and Cynicism at the Urban Margins
This article examines the connections between participants in the illicit drug trade and members of state security forces to understand how they impact everyday understandings of the law. The authors used ethnographic fieldwork in a poor, high-crime district in Argentina and information gathered for a court case involving a drug trafficking group active in the same area as the basis for their research.

Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio)
This article is a study using crude oil as an example of an environmental stressor in adult zebrafish. The offspring obtained were then assessed for transgenerational epigenetic transfer of oil-induced phenotypes. The authors conclude that epigenetic transgenerational inheritance can lead to an immediate and simultaneous inheritance of both beneficial and maladaptive traits in a large proportion of the F1 larvae. The adaptive responses may help fish populations survive when facing transient environmental stressors.

Sarcoplasmic reticulum Ca²⁺-ATPase (SERCA) activity during the transition to endothermy in an altricial bird
Article describes SERCA activity in the pectoralis muscle and heart ventricle of red-winged blackbird (Agelaius phoeniceus) nestlings, fledglings and adults. Additionally, using a diet manipulation, the authors tested the hypothesis that muscle SERCA activity is affected by dietary fatty acid composition, as has been shown in some previous studies.

Managing Sudden Loss
Managers often face tough, emotional situations at work. One of the biggest is guiding employees and departments successfully through the loss of a coworker. Not only are there emotional components but there are also more technical and procedural responsibilities that may be overlooked. These facilities, technological, and human resources tasks need to be handled sensitively and in a timely manner. Remembering whom to contact, what property needs to be considered, and how to produce final paychecks are just a few of the concerns managers will face in a trying time. This guide aims to serve as a checklist of the basic components and tasks managers will face after the sudden loss of an employee.

UV and infrared absorption spectra and 248 nm photolysis of maleic anhydride (C₄H₂O₃)
This article investigates maleic anhydride (C₂H₂(CO)₂O, Furan-2,5-dione) that is emitted into or formed in the atmosphere during bio-mass burning events as well as being a photochemical degradation product of some aromatic volatile organic compounds. The photochemical fate of maleic anhydride, however, is presently not well enough characterized to enable modeling of its impact on the environment and human health. In this study, the room temperature UV and infrared absorption spectra of maleic anhydride were measured and quantified using several complementary calibration methods.

Building a Trusted Framework for Coordinating OA Monograph Usage Data
The Andrew W. Mellon Foundation recently funded a study of the landscape of usage data for open-access scholarly monographs and an investigation of the viability of creating a data trust for sharing of usage data among stakeholders in the publishing ecosystem. In spring 2019, the Book Industry Study Group (BISG) will publish a final white paper that takes into account feedback from the community during a consultation period. This presentation will provide a summary of the main findings and proposals of the forthcoming white paper.

Atomic layer deposition of h-BN(0001) multilayers on Ni(111) and chemical vapor deposition of graphene on h-BN(0001)/Ni(111)
Article studying atomic layer deposition. In situ direct, epitaxial growth of multilayers of hexagonal boron nitride (h-BN) and graphene without physical transfer is of significant interest for the scalable production of graphene/h-BN heterostructures for device applications. Deposition on magnetic substrates is of particular interest for spin tunneling applications. X-ray photoelectron spectroscopy and low energy electron diffraction demonstrate epitaxial atomic-layer deposition (ALD) of multilayer h-BN(0001) on Ni(111) and subsequent deposition of azimuthally-aligned multilayer graphene on h-BN(0001)/Ni(111) by chemical vapor deposition. Boron nitride ALD was accomplished with alternating cycles of BCl₃/NH₃ at a 600 K substrate temperature, and subsequent annealing in ultrahigh vacuum. Subsequent deposition of graphene was achieved by chemical vapor deposition using ethylene (CH₂CH₂) at 1000 K.

Psychosocial predictors of physical activity and health-related quality of life among Shanghai working adults
This article investigates the psychosocial predictors of physical activity and quality of life (QOL) among Shanghai working adults. Stress and social support from friends were two important sources of self-efficacy, all of which facilitated more physical activity participation. Lower stress, higher social support, and more physical activity may directly increase QOL among Shanghai working adults.

ICT in Higher Education: An Exploration of Practices in Malaysian Universities
Article investigating the use of information and communication technologies (ICTs) in education. To investigate this issue, the technology adoption and gratification (TAG) model was validated and used to examine Malaysian university teachers' adoption and gratification of ICT for teaching and research purposes and then used to investigate the moderating effect of universities in different regions. This paper confirms the utility of the TAG model for comparing teachers' adoption and gratification of ICT.
