Biomedical Journals' Standards for Digital Images in Biomedical Articles

Addeane Caelleigh
Standards for appropriate manipulation of digital data have developed more slowly than has the software for manipulating the images. Half of all cases now investigated by the federal Office of Research Integrity involve questions about digital images. The authors examined the instructions to authors and related material for 446 biomedical journals to identify their guidelines and/or requirements for digital data images. Half (50%) of the journals had no guidelines or only referred to 'art' (printed...

Transport of Large-Scale Poloidal Flux in Black Hole Accretion

John Hawley
We report on a global, three-dimensional GRMHD simulation of an accretion torus embedded in a large-scale vertical magnetic field orbiting a Schwarzschild black hole. This simulation investigates how a large-scale vertical field evolves within a turbulent accretion disk and whether global magnetic field configurations suitable for launching jets and winds can develop. We find that a “coronal mechanism” of magnetic flux motion, which operates largely outside the disk body, dominates global flux evolution. In this...

The notes from nature tool for unlocking biodiversity records from museum records through citizen science

Andrew Sallans, Andrew Hill, Robert Guralnick, Arfon Smith, Rosemary Gillespie, Michael Denslow, Joyce Gross, Zack Murrell, Tim Conyers, Peter Oboyski, Joan Ball, Andrea Thomer, Robert Prys-Jones, Javier de la Torre, Patrick Kociolek & Lucy Fortson
Legacy data from natural history collections contain invaluable and irreplaceable information about biodiversity in the recent past, providing a baseline for detecting change and forecasting the future of biodiversity on a human-dominated planet. However, these data are often not available in formats that facilitate use and synthesis. New approaches are needed to enhance the rates of digitization and data quality improvement. Notes from Nature provides one such novel approach by asking citizen scientists to help...

Overcoming the Fear of Gaming: A Strategy for Incorporating Games into Teaching and Learning

Rafael Alvarado
The effective use of games in academia requires a critical approach to the medium and a willingness to let go of the learning process and harness its outcomes

Accretion disk dynamics, photoionized plasmas, and stellar opacities

John Hawley
We present a brief review on the atomic kinetics, modeling and interpretation of astrophysical observations, and laboratory astrophysics experiments. The emphasis is on benchmarking of opacity calculations relevant for solar structure models, photoionized plasmas research, the magnetohydrodynamic numerical simulation of accretion disk dynamics, and a connection between radiation transport effects and plasma source geometry details. Specific cases of application are discussed with relevance to recent and proposed laboratory astrophysics experiments as well as Chandra and...

Structure and evolution of the global seafood trade network

Jessica Gephart & Michael Pace
The food production system is increasingly global and seafood is among the most highly traded commodities. Global trade can improve food security by providing access to a greater variety of foods, increasing wealth, buffering against local supply shocks, and benefit the environment by increasing overall use efficiency for some resources. However, global trade can also expose countries to external supply shocks and degrade the environment by increasing resource demand and loosening feedbacks between consumers and...

Model Language for Research Data Management Policies

William Corey, Nathan Hall, Wendy Mann & Tom Wilson
This proposal was drafted by a Working Group of the ASERL/SURA Research Data Coordinating Committee. The purpose of this document is to provide model language for universities to consider when drafting policy to support data management practices and infrastructure at their institutions. ASERL/SURA member institutions may not need all of the sections in this document. Each institution should include the sections that are relevant for their situation, and modify content as necessary. Much of this...

Lower neighborhood quality in adolescence predicts higher mesolimbic sensitivity to reward anticipation in adulthood

Marlen Gonzalez, Joseph Allen & James Coan
Life history theory suggests that adult reward sensitivity should be best explained by childhood, but not current, socioeconomic conditions. In this functional magnetic resonance imaging (fMRI) study, 83 participants from a larger longitudinal sample completed the monetary incentive delay (MID) task in adulthood (∼25 years old). Parent-reports of neighborhood quality and parental SES were collected when participants were 13 years of age. Current income level was collected concurrently with scanning. Lower adolescent neighborhood quality, but...

Resilience and recovery potential of duneland vegetation in the southern Kalahari

Abinash Bhattachan, Paolo D'Odorico, Kebonyethata Dintwe, Gregory Okin & Scott Collins
Many dune fields around the world have undergone alternating periods of mobilization and stabilization in response to changes in wind power and rainfall. However, in modern times disturbances associated with land use are believed to be a dominant factor contributing to the activation of stabilized vegetated dunes in drylands, while the reduction in human activities such as grazing and farming may lead to stabilization of once active dune fields. The Kalahari region of southern Africa...

PbSe quantum dot based luminescent solar concentrators

Dennis Waldron, Amanda Preske, Joseph Zawodny, Todd Krauss & Mool Gupta
The results are presented for luminescent solar concentrators (LSCs) fabricated with poly(lauryl methacrylate-co-ethylene glycol dimethacrylate) (P(LMA-co-EGDMA)) and Angstrom Bond, Inc. AB9093 acrylic epoxy matrix, high quantum yield (> 70%) PbSe quantum dots (QDs) and silicon photovoltaic (Si PV) cells. LSCs were tested under a lamp with broadband illumination, photon flux-matched to a standard solar spectrum and verified under a calibrated solar lamp source. The P(LMA-co-EGDMA) sample demonstrated the highest power conversion efficiency of any known...

The case for character displacement in plants

Carolyn Beans
The evidence for character displacement as a widespread response to competition is now building. This progress is largely the result of the establishment of rigorous criteria for demonstrating character displacement in the animal literature. There are, however, relatively few well-supported examples of character displacement in plants. This review explores the potential for character displacement in plants by addressing the following questions: (1) Why aren’t examples of character displacement in plants more common? (2) What are...

Secretory vesicles deliver Cdc42p to sites of polarized growth in S. cerevisiae

Keith Kozminski & Shubha Dighe
he activation and localization of the Rho-family GTPase Cdc42p at one pole of a cell is necessary for maintaining an axis of polarized growth in many animal and fungal cells. How the asymmetric distribution of this key regulator of polarized morphogenesis is maintained is not fully understood, though divergent models have emerged from a congruence of multiple studies, including one that posits a role for polarized secretion. Here we show with S. cerevisiae that Cdc42p...

Corporate Environmental Performance and Shareholder Value

Mark White
The role corporations should play in achieving social objectives is a topic with a lengthy history of debate. Significant recent interest has focused on the impact corporate activities have upon the natural world and the environment. This paper examines the link between corporate environmental responsibility--measured by environmental reputation indices--and shareholder wealth. Investors in a portfolio of firms enjoying above-average reputations for corporate environmental responsibility earn risk-adjusted returns significantly greater than either the overall market or...
