This paper examines the chief findings of research conducted on policies to foster off-hour deliveries (OHDs) in the New York City metropolitan area. The goal was to estimate the overall impacts of eventual full implementation of an OHD program. As part of the research, a system of incentives was designed for the receivers of deliveries the system combined Global Positioning System (GPS) remote sensing monitoring with GPS-enabled smart phones to induce a shift of deliveries to the off-hours from 7:00 p.m. to 6:00 a.m. The concept was pilot tested in Manhattan by 33 companies that switched delivery operations to the off-hours for a period of 1 month. At the in-depth interviews conducted after the test, the participants reported being very satisfied with the experience. As an alternative to road pricing schemes that target freight carriers, this was the first real-life trial of the use of financial incentives to delivery receivers. The analyses indicate that the economic benefits of a full implementation of the OHD program are in the range of $147 to $193 million per year, corresponding to savings on travel time and environmental pollution for regular-hour traffic as well as productivity increases for the freight industry. The pilot test also highlighted the great potential of unassisted OHD-that is, OHD made without personnel from the receiving establishment present-because almost all participants who used this modality decided to continue receiving OHD even after the financial incentive ended.

The joint RTCA SC-217/EUROCAE WG-44 committee completed the latest revisions of the AMDB user requirements and interchange specifications DO-272C and DO-291B in 2011. One of the major novelties is the introduction of the ASRN. The ASRN supports manual editing of taxi routes, data link transmissions of taxi routes, and highly detailed display of taxi routes in the cockpit. © 2013 IEEE.

Climatic Change | Year: 2011
In 2007, the CNA Military Advisory Board (MAB), an expert panel composed of 11 retired admirals and generals from the United States, identified climate change as a "threat multiplier" for instability in some of the most volatile regions of the world. (CNA MAB National security and the threat of climate change2007)The Department of Defense reached a similar conclusion in last year's Quadrennial Defense Review-a legislatively mandated analysis of the Defense Department's strategy and priorities. This document frames the long-term course for policy decision-making at the highest levels. The reports demonstrate that climate change and energy are now mainstream elements of national security planning, and can be assessed within the frameworks used to evaluate other threats, risks, and responses. However, the exact magnitude of the threat posed by climate change is difficult to calibrate in part because the language used by scientists to predict uncertainty and the confidence levels of judgments is not sufficiently clear. The defense community has a vast amount of experience exploring and dealing with uncertainty. Scientists trying to better describe the effects of climate change may be able to draw lessons from the defense community's approach to uncertainty including how to better communicate findings to wide audiences including policy-makers. © 2011 Springer Science+Business Media B.V.

Manufactured nanomaterials (MNs) are commonly considered to be commercial products possessing at least one dimension in the size range of 10 -9 m to 10 -7 m. As particles in this size range represent the smaller fraction of colloidal particles characterized by dimensions of 10 -9 m to 10 -6 m, they differ from both molecular species and bulk particulate matter in the sense that they are unlikely to exhibit significant settling under normal gravitational conditions and they are also likely to exhibit significantly diminished diffusivities (when compared to truly dissolved species) in environmental media. As air/water, air/soil, and water/soil inter medium transport is governed by diffusive processes in the absence of significant gravitational and inertial impaction processes in environmental systems, models of MN environmental inter medium transport behavior will likely require an emphasis on kinetic approaches. This review focuses on the likely environmental fate and transport of MNs in atmospheric and aquatic systems. Should significant atmospheric MNs emission occur, previous observations suggest that MNs may likely exhibit an atmospheric residence time of ten to twenty days. Moreover, while atmospheric MN aggregates in a size range of 10 -7 m to 10 -6 m will likely be most mobile, they are least likely to deposit in the human respiratory system. An examination of various procedures including the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory of colloidal particle suspension stability in water indicates that more sophisticated approaches maybe necessary in order to develop aquatic exposure models of acceptable uncertainty. In addition, concepts such as Critical Coagulation Concentrations and Critical Zeta Potentials may prove to be quite useful in environmental aquatic exposure assessments. © 2011 by the authors; licensee MDPI, Basel, Switzerland.

Identification and counting of different oxygen-containing functional groups in 40 small aromatic analytes, including a lignin monomer, was explored using a linear quadrupole ion trap (LQIT) mass spectrometer. The analytes were evaporated and ionized by negative-mode electrospray ionization (ESI). In an effort to cleave off all of the functionalities, one at a time, the deprotonated analytes were then subjected to multiple consecutive collision-activated dissociation (CAD) events until no more fragmentation was observed (up to MS 5). In most cases, the number and types of functionalities could be determined. This approach was demonstrated to be feasible on the high-performance liquid chromatographic (HPLC) time scale. Hence, valuable structural information can be obtained for previously unknown aromatic analytes directly in complex mixtures, such as lignin degradation products. © 2011 American Chemical Society.

This article addresses the gap in the literature on U.S. domestic terrorism and counterterrorism in the 1970s by examining a once-notorious but now largely forgotten terrorist group, the Black Liberation Army (BLA). An outgrowth of the Black Panther Party, the BLA was directly responsible for at least 20 fatalities, making it amongst the most lethal "homegrown" U.S. groups of the period. This article seeks to shed new light on the BLA by exploring its relatively short but violent trajectory. By focusing on the group's origins, operations, ideology, and structure, the BLA can be understood as part of a wider landscape of homegrown political violence. The BLA emerged during the waning phase of a protest cycle that included the civil rights, Black Power, and anti-war movements. Like other terrorist groups before and after, the BLA claimed to be acting in self-defense and on behalf of the people, presenting itself as an army resisting police occupation of minority communities. With the collapse of the extreme Left in the mid- 1970s, the BLA's prospects for creating a broader revolutionary base became remote. The article also examines law-enforcement responses to the BLA and the competing ways in which the Federal Bureau of Investigation and local police (and in particular, the New York Police Department) framed and countered the BLA threat. © Taylor & Francis Group, LLC.
