Las Vegas, NV, United States

University of Nevada-Las Vegas is a public research university located in the Las Vegas suburb of Paradise, Nevada, USA. The 358-acre campus is located approximately 1.5-mile east of the Las Vegas Strip. The university includes the Shadow Lane Campus, located just east of the University Medical Center of Southern Nevada, which houses the School of Dental Medicine— the only dental school in the state of Nevada. In addition, UNLV's law school, the William Boyd School of Law, is also the only law school in the state.Noted for its strong emphasis on science and technology, business management, and the law programs, the university is classified a "research-intensive university" by the Carnegie Foundation for the Advancement of Teaching. The William Harrah College of Hotel Administration is annually ranked among the top hospitality programs in the United States due to the university's proximity to the Las Vegas Strip. Its famed Thomas & Mack Center hosted the 2007 NBA All-Star Game, concerts, as well as lectures by Bill Clinton and Mikhail Gorbachev as part of various UNLV-affiliated lecture series. Wikipedia.

The physical nature of fast radio bursts (FRBs), a new type of cosmological transient discovered recently, is not known. It has been suggested that FRBs can be produced when a spinning supra-massive neutron star loses centrifugal support and collapses to a black hole. Here, we suggest that such implosions can happen in supra-massive neutron stars shortly (hundreds to thousands of seconds) after their births, and an observational signature of such implosions may have been observed in the X-ray afterglows of some long and short gamma-ray bursts (GRBs). Within this picture, a small fraction of FRBs would be physically connected to GRBs. We discuss possible multi-wavelength electromagnetic signals and gravitational wave signals that might be associated with FRBs, and propose an observational campaign to unveil the physical nature of FRBs. In particular, we strongly encourage a rapid radio follow-up observation of GRBs starting from 100 s after a GRB trigger. © 2014. The American Astronomical Society. All rights reserved. Source

Child Abuse and Neglect | Year: 2015

This article constitutes a 20-year update to a previous publication (. Pelton, 1994), which showed that there is overwhelming evidence that poverty and low income are strongly related to child abuse and neglect. Subsequent evidence shows that the relationship continues to be strong. In addition, there is further evidence since the 1994 publication that this relation is not substantially due to class bias. Yet it is suggested that class bias does exist within the system. There is also further evidence that decreases in child maltreatment follow increases in material supports, and that job loss bears a complex relationship to child maltreatment. Findings pertaining to racial bias within the child welfare system continue to be mixed, but leave no doubt that racial disproportionalities within the system are overwhelmingly related to racial disproportionalities in the poverty population. There is continuing evidence that children placed in foster care are predominantly from impoverished families, and that changes in the level of material supports are related to risk of placement. It is suggested that the fact that there are nearly one million children in out-of-home placement (foster care and child-welfare involved adoption, combined) is indicative of the continuing dysfunction of the child welfare system, and that the differential response paradigm has not altered this dysfunction. A proposal for a fundamental restructuring of the child welfare system is recommended and restated here. Prospects for such change are briefly discussed. Also, to reduce poverty, a previously proposed universal social dividend and taxation system is briefly discussed and recommended. © 2014 Elsevier Ltd. Source

Ecologists have studied plant succession for over a hundred years, yet our understanding of the nature of this process is incomplete, particularly in relation to its response to new human perturbations and the need to manipulate it during ecological restoration. We demonstrate how plant succession can be understood better when it is placed in the broadest possible temporal context. We further show how plant succession can be central to the development of a framework that integrates a spectrum of ecological processes, which occur over time scales ranging from seconds to millions of years. This novel framework helps us understand the impacts of human perturbations on successional trajectories, ecosystem recovery, and global environmental change. © 2014 Elsevier Ltd. Source

Magnetotactic bacteria (MTB) are widespread, motile, diverse prokaryotes that biomineralize a unique organelle called the magnetosome. Magnetosomes consist of a nano-sized crystal of a magnetic iron mineral that is enveloped by a lipid bilayer membrane. In cells of almost all MTB, magnetosomes are organized as a wellordered chain. The magnetosome chain causes the cell to behave like a motile, miniature compass needle where the cell aligns and swims parallel to magnetic field lines. MTB are found in almost all types of aquatic environments, where they can account for an important part of the bacterial biomass. The genes responsible for magnetosome biomineralization are organized as clusters in the genomes of MTB, in some as a magnetosome genomic island. The functions of a number of magnetosome genes and their associated proteins in magnetosome synthesis and construction of the mag- netosome chain have now been elucidated. The origin of magnetotaxis appears to be monophyletic; that is, it developed in a common ancestor to all MTB, although horizontal gene transfer of magnetosome genes also appears to play a role in their distribution. The purpose of this review, based on recent progress in this field, is focused on the diversity and the ecology of the MTB and also the evolution and transfer of the molecular determinants involved in magnetosome formation.

A new framework for thinking about the deformation behavior of rocks and other heterogeneous polycrystalline materials is proposed, based on understanding the patterns of stress transmission through these materials. Here, using finite element models, I show that stress percolates through polycrystalline materials that have heterogeneous elastic and plastic properties of the same order as those found in rocks. The pattern of stress percolation is related to the degree of heterogeneity in and statistical distribution of the elastic and plastic properties of the constituent grains in the aggregate. The development of these stress patterns leads directly to shear localization, and their existence provides insight into the formation of rhythmic features such as compositional banding and foliation in rocks that are reacting or dissolving while being deformed. In addition, this framework provides a foundation for understanding and predicting the macroscopic rheology of polycrystalline materials based on single-crystal elastic and plastic mechanical properties. © 2013 Macmillan Publishers Limited.
