Justice in Review: New Trends in State Sentencing and Corrections 2014-2015
In 2014 and 2015, 46 states enacted at least 201 bills, executive orders, and ballot initiatives to reform at least one aspect of their sentencing and corrections systems. In conducting this review of state criminal justice reforms, Vera found that most of the policy changes focused on three areas: creating or expanding opportunities to divert people away from the criminal justice system; reducing prison populations by enacting sentencing reform, expanding opportunities for early release from prison, and reducing the number of people admitted to prison for violating the terms of their community supervision; and supporting reentry into the community from prison. By providing concise summaries of representative reforms in each of these areas, this report serves as a practical guide for other state and federal policymakers looking to affect similar changes in criminal justice policy
Extrapolation of Animal Research Data to Humans: An Analysis of the Evidence
The ethical arguments against animal experimentation remain ever-strong. In addition, the scientific case against the use of animals in research grows more compelling, with exponential progress in the development of alternative methods and new research technologies. The Dutch authorities recently announced an ambitious, but welcome, proposal to phase out âthe use of laboratory animals in regulatory safety testing of chemicals, food ingredients, pesticides and (veterinary) medicinesâ by 2025, as well as âthe use of laboratory animals for the release of biological products, such as vaccinesâ (Netherlands National Committee for the protection of animals used for scientific purposes, NCad, 2016, p. 3). National government departments (e.g., the United Kingdom, UK, Home Office) have stated that alternatives to animals are now considered necessary for scientific as much as ethical reasons, also conceding that pressure exists within the research community to use animals in order to get published. Furthermore, only 20% of animal tests across the European Union (EU) each year are conducted to meet regulatory requirements, with the vast majority carried out as basic research (including basic medical research) or breeding of genetically modified (GM) animals at academic institutions (European Commission, 2013b)

Pedestrian injuries in collisions with pedal cycles in the context of increased active travel: Trends in England, 2005-2015.
Introduction: Increasing levels of active travel in the population brings many public health benefits, but may also change the risks of road injury for different road users. We examined changes in rates of pedestrian injuries resulting from collisions with pedal cycles and motor vehicles in England during 2005-2015, a period of increased cycling activity, and described the gender, age distribution and locations of pedestrians injured in collisions with pedal cycles and motor vehicles. Methods: Collisions data were obtained from police STATS19 datasets. We used two measures of cycle/motor vehicle use; miles per annum, and estimated average travel time, and assessed evidence for trends towards increase over time using Poisson regression analysis. Results: There were 3414 pedestrians injured in collisions with one or more pedal cycles in England during 2005-2015, 763 of whom were killed or seriously injured (KSI). This accounted for 1.3% of the total pedestrians KSI from all vehicles. Of those KSI in collisions with cycles, 62% were female; 42% over the age of 60; 26% were on the footway or verge and 24% were on a pedestrian crossing. There was a 6% (IRR 1.056; 95% CI 1.032-1.080, p < 0.001) annual increase in the pedestrian KSI rate per billion vehicle miles cycled in England over the time span. This increase was disproportionate to the increase in cycle use measured by vehicle miles or time spent cycling. Conclusions: Increases in cycling were associated with disproportionate increases in pedestrian injuries in collisions with pedal cycles in England, although these collisions remain a very small proportion of all road injury. Increased active travel is essential for meeting a range of public health goals, but needs to be planned for with consideration for potential impact on pedestrians, particularly older citizens
PbTi1-xPdxO3: A New Room-temperature Magnetoelectric Multiferroic Device Material
There have been a large number of papers on bismuth ferrite (BiFeO3) over the
past few years, trying to exploit its room-temperature magnetoelectric
multiferroic properties. Although these are attractive, BiFeO3 is not the ideal
multiferroic, due to weak magnetization and the difficulty in limiting leakage
currents. Thus there is an ongoing search for alternatives, including such
materials as gallium ferrite (GaFeO3). In the present work we report a
comprehensive study of the perovskite PbTi1-xPdxO3 with 0 < x < 0.3. Our study
includes dielectric, impedance and magnetization measurements, conductivity
analysis and study of crystallographic phases present in the samples with
special attention paid to minor phases, identified as PdO, PbPdO2, and Pd3Pb.
The work is remarkable in two ways: Pd is difficult to substitute into ABO3
perovskite oxides (where it might be useful for catalysis), and Pd is magnetic
under only unusual conditions (under strain or internal electric fields). The
new material, as a PZT derivative, is expected to have much stronger
piezoelectric properties than BiFeO3
Trends in Use of Scientific Workflows: Insights from a Public Repository and Recommendations for Best Practice
Scientific workflows are typically used to automate the processing, analysis and management of scientific data. Most scientific workflow programs provide a user-friendly graphical user interface that enables scientists to more easily create and visualize complex workflows that may be comprised of dozens of processing and analytical steps. Furthermore, many workflows provide mechanisms for tracing provenance and methodologies that foster reproducible science. Despite their potential for enabling science, few studies have examined how the process of creating, executing, and sharing workflows can be improved. In order to promote open discourse and access to scientific methods as well as data, we analyzed a wide variety of workflow systems and publicly available workflows on the public repository myExperiment. It is hoped that understanding the usage of workflows and developing a set of recommended best practices will lead to increased contribution of workflows to the public domain
Understanding the role of crystallographic shear on the electrochemical behavior of niobium oxyfluorides
The effects of shear planes in perovskite materials have been studied in order to identify their role in the electrochemical behavior of Liâș intercalation hosts. These planes modulate the structural stability and ionic transport pathways and therefore play an intimate role in the characteristics and performance of shear compounds. Herein, two Nb-based compounds, NbOâF and NbâOâF, were chosen as representative perovskite and shear derivatives respectively to investigate the role of crystallographic shear. A series of operando measurements, including X-ray diffraction and X-ray absorption spectroscopy, in conjunction with structural analysis, Raman spectroscopy, and detailed electrochemical studies identified the effect of shear planes. It was found that shear planes led to increased structural stability during Liâș (de)intercalation with shear layers being maintained, while perovskite layers were seen to degrade rapidly. However, disordering in the shear plane stacking introduced during delithiation ultimately led to poor capacity retention despite structural maintenance as Liâș diffusion channels are disrupted
