Transit Industry Gears Up and Responds to Climate Change Challenges

The transit industry in the United States is preparing for growth as the world deals with climate change and it is applying various methods to measure and monitor its impact on the environment. Working with local, state, and federal governments, transit agencies have adapted many commonsense solutions. Now the American Public Transportation Association is putting together standards and best practices to encourage the industry and inform the public about the benefits of public transportation to the environment, helping our nation join the rest of the world. It is also developing and applying new transit strategies that will attract more riders and reduce greenhouse gas emissions. Portland, Oregon's Tri-Met, New York's Metropolitan Transportation Authority, and the Utah Transit Authority are leading the industry. Portland, Oregon's Tri-Met General Manager, who chairs the industry's Sustainability Committee for the American Public Transit Association has been leading by example with an Environmental Management System that addresses greenhouse gas, pollution, waste, inefficiency, and congestion. New York and Utah are recording greenhouse gases with the Climate Registry. Many agencies are developing new strategies that are attracting more riders and experiencing an intermodal shift to buses and trains. Meanwhile, developing countries are able to increase service and pay for it by selling carbon credits.     

Adaptation and evaluation of the PrepFiler™ DNA extraction technology in an automated forensic DNA analysis process with emphasis on DNA yield, inhibitor removal and contamination security

Within the initial step of the forensic DNA analysis process, the DNA extraction efficiency and especially the removal of potential PCR inhibitors is crucial for subsequent steps, e.g. quantification by real-time PCR and amplification of short tandem repeats (STRs). The protocol of the PrepFiler™ Forensic DNA Extraction Kit was optimized for the application on a Tecan liquid handling workstation Freedom EVO^® 150. This modified application of the PrepFiler™ technology was compared with respect to DNA yield, sensitivity and the ability to remove potential PCR inhibitors to an established routine method working on the same liquid handling workstation based on ChargeSwitch^® Technology (CST) from Invitrogen.     

Children's Rights and the Politics of Food: Big Food Versus Little People

This article traces the battle in the United States during the Obama administration, continuing into the Trump administration, to protect children's rights to food. It explores barriers to development of sound, science‐based food policies, including the refusal to recognize food as a human right, anti‐science denialism, hostility toward government regulation, and relative powerlessness of children. It points to the role of a “Big Food Pyramid” composed of powerful food industry and large scale distribution and marketing interests in blocking sound policies in prenatal and infant nutrition, school lunches, SNAP and WIC, the marketing to children of high fat and fructose‐laden products, and campaigns to increase youth fitness. While predicting a continuing assault at the federal level on children's rights to safe and healthy foods, the article highlights the positive role of consumer demand in shaping marketing, labeling and production of food and opportunities for leaders in the food industry and in government at local, municipal and state levels to continue the battle for sound food policies.     

Characterizing the Performance of Pipe Bombs

Pipe bombs of steel or PVC fragment in reproducible patterns when similarly configured. The power of the explosion correlates with number, mass, and size of the fragments recovered, where a large number of small, low‐mass fragments indicate a high‐power event and vice versa. In discussing performance, describing pipe fragmentation pattern by fragment weight distribution mapping (FWDM) or fragment surface area distribution mapping (FSADM) was useful. When fillers detonated, detonation velocities of ~4.4 mm/μs were measured. In such cases, side walls of the pipe were thrown first; the average fragment velocity was ~1000 km/s. In deflagrations, the end cap was first thrown; fragment velocities were only ~240 km/s. Blast overpressures varied; at 10 feet, 2 × 12 inch steel pipes containing ~550 g of detonable mixture produced overpressures of 5–6 psi; similar nondetonating pipes produced less than 2 psi. Maximum fragment throw distances were 250–300 m, with an average of ~100 m.     

Job Stress,Job Involvement,Job Satisfaction,and Organizational Commitment and Their Associations with Job Burnout Among Indian Police Officers: a Research Note

Job burnout can negatively impact individual officers, the organization that employs the burned out officers, citizens with whom these officers directly interact, and the community more broadly. The vast majority of the empirical research on burnout has been based on Western police officers. The present study extends our understanding of the associations that job stress, job involvement, job satisfaction, affective commitment, and continuance commitment have with the three dimensions of burnout (emotional exhaustion, depersonalization, and a reduced sense of accomplishment) among Indian police officers. Ordinary least square (OLS) regression analysis was used to examine survey data from 827 police officers in the Sonipat and Rohtak districts of the Indian state of Haryana using a systematic random sample. The findings indicate that job involvement and job satisfaction were associated with lower levels of all three dimensions of burnout. Job stress was associated with emotional and reduced accomplishment burnout. High affective commitment was associated with lower levels of a reduced sense of personal accomplishment, while continuance commitment was associated with higher levels of emotional and depersonalization burnout. The results suggest that job stress, job involvement, job satisfaction, affective commitment, and continuance commitment have effects on burnout among Indian officers, as has been found among Western officers. As such, police scholars and administrators should focus on reducing job stress and continuance commitment and increasing job involvement, job satisfaction, and affective commitment among officers.     

A Carbon Dioxide Fatality from Dry Ice

Abstract:  This report documents a rare case of carbon dioxide intoxication in a young healthy male. The deceased hid in a small plastic container, size 1.5 × 1 × 1 m, and within 5 min he was located suffering convulsions and was reported as dead within minutes. Scene investigation revealed dry ice in the container. Autopsy findings were unremarkable. The probable cause of the convulsions was carbon dioxide intoxication due to both the dry ice sublimation and the small confined space in which he was hiding. This report emphasizes the significance of scene investigation in establishing the cause of the death.     

The Relationship Between Deprivation and Forensic Opportunities with Stolen Vehicles

Abstract:  Collection and interpretation of forensic intelligence (primarily through DNA and fingerprint identifications) is an integral part of the investigation of criminal offenses ranging from burglary and vehicle crime to major crime. The forensic contribution depends not only on the successful recovery of material, but also the ability to identify potential offenders and apply this intelligence to solve the crime. This study examines burglary and vehicle crimes investigated by Northamptonshire Police (U.K.) by analyzing relationships between deprivation of a crime location and the recovery and identification of DNA and fingerprint material. The results show that, for stolen vehicles, although significantly more forensic material (both DNA and fingerprints) is recovered and identified in more deprived neighborhoods, this does not lead to a corresponding increase in solved cases. These findings are considered in relation to previous studies, which have advocated the prioritization of resources at crime scenes most likely to yield forensic material.
