Formulating a Strategy for Securing High-Speed Rail in the United States, Research Report 12-03

This report presents an analysis of information relating to attacks, attempted attacks, and plots against high-speed rail (HSR) systems. It draws upon empirical data from MTI’s Database of Terrorist and Serious Criminal Attacks Against Public Surface Transportation and from reviews of selected HSR systems, including onsite observations. The report also examines the history of safety accidents and other HSR incidents that resulted in fatalities, injuries, or extensive asset damage to examine the inherent vulnerabilities (and strengths) of HSR systems and how these might affect the consequences of terrorist attacks. The study is divided into three parts: (1) an examination of security principles and measures; (2) an empirical examination of 33 attacks against HSR targets and a comparison of attacks against HSR targets with those against non-HSR targets; and (3) an examination of 73 safety incidents on 12 HRS systems. The purpose of this study is to develop an overall strategy for HSR security and to identify measures that could be applied to HSR systems currently under development in the United States. It is hoped that the report will provide useful guidance to both governmental authorities and transportation operators of current and future HSR systems

Issues of Selection in Human Survivorship: A Theory of Mortality Change from the Mid-Eighteenth to the Early Twenty First Century

Is variation in empirical mortality across populations consistent with a hypothesis of selec-tion? To examine this proposition an extended frailty mortality model is put forward; incor-porating biological frailty; a common non-parametric hazard, joint for men and women, rep-resenting endogenous mortality in terms of degenerative aging (senescence); and environ-mental influence on survivorship. As the model is fitted to empirical cohort mortality exhibit-ing extreme variation, biological aging is identified up to a multiplicative factor. Mortality of elected cohorts born in Sweden, Denmark, and Iceland during the past 250 years and in Japan any ten years between 1950 and 1990 is approached appropriately by the model. Reduced natural selection may account for a substantial part of the empirical mortality change in the course of the demographic transition. Survivorship in the late nineteenth and the twentieth century ties selection to major medical advances and rapid recent mortality decline, probably with consequences for future health and survivorship.biodemography; congenital frailty; selection; heterogeneity; cohort mortality; stochastic micro-simulation; longevity

An exploratory study into the effects of a 20 minute crushed ice application on knee joint position sense during a small knee bend.

Objectives The effect of cryotherapy on joint positioning presents conflicting debates as to whether individuals are at an increased risk of injury when returning to play or activity immediately following cryotherapy application at the knee. The aim of this study was to investigate whether a 20 minute application of crushed ice at the knee immediately affects knee joint position sense during a small knee bend. Design Pre and post-intervention. Setting University movement analysis laboratory. Participants Eleven healthy male participants. Main Outcome Measures Kinematics of the knee were measured during a weight bearing functional task pre and post cryotherapy intervention using three-dimensional motion analysis (Qualisys Medical AB Gothenburg, Sweden). Tissue cooling was measured via a digital thermometer at the knee. Results Results demonstrated significant reductions in the ability to accurately replicate knee joint positioning in both sagittal (P=.035) and coronal (P=.011) planes during the descent phase of a small knee bend following cryotherapy. Conclusion In conclusion a twenty minute application of crushed ice to the knee has an adverse effect on knee joint repositioning. Team doctors, clinicians, therapists and athletes should consider these findings when deciding to return an athlete to functional weight bearing tasks immediately following ice application at the knee, due to the potential increase risk of injury

Perceived information technology risks and attitudes

Risk has been a focal dimension in much of the debate about attitudes toward technology. In the present paper, the development of research on risk perception is reviewed, from its beginnings in the end of the 1960's. The received view on factors in risk perception is that of the psychometric model and social trust. It is pointed out that this approach gives only an incomplete understanding of risk and risk acceptance, and some missing elements are delineated, such as Tampering with Nature, which is an important factor in technology acceptance, and trust (or distrust) in science, and the embracing of alternative views on the nature of the world and knowledge (New Age). Several methodological points are also important. Risks should be studied with regard to one’s own personal (personal risk), and to others (general risk), because these dimensions often differ and they have different implications. It should also be observed that the most important risk aspect is severity of consequences of unwanted events or accidents, not their probability. When it comes to attitudes toward technology it is argued that the replaceability of a technology is an important factor. IT risks have been investigated in a major survey carried out with a representative sample of the Swedish population. The main finding was that IT risks were seen as pertinent mainly to others, implying that people (rightly or wrongly) perceived that they could protect themselves from IT risks. IT risks are finally regarded in the light of Stigma Theory, which has been devised to understand some social and political reactions to risks, and it is held that it is unlikely that IT will become a stigmatized technology, partly because it is seen as irreplaceable. Yet, many IT risks are very real and many people are aware of them. In particular, personal integrity is threatened and the very novelty of the technology involved is probably the cause why ethical and legal developments lag far behind. Initial one-sided positive statements about IT are likely to be followed by more sober assessments of this technology which brings many blessings but also an increasing number of serious risks.risk perception; information technology; attitudes toward technology

ZeroWasteWater: short-cycling of wastewater resources for sustainable cities of the future

Sewage treatment relies mainly on conventional activated sludge (CAS) systems, reaching sufficiently low pollutant effluent levels. Yet, CAS has a low cost-effectiveness and recovery potential and a high electricity demand and environmental footprint. By 2050, globally we have to solve severe water and phosphorus shortages while significantly decreasing greenhouse gas emissions. In this review and opinion paper, the ZeroWasteWater concept is proposed as a sustainable centralised technology train to short-cycle water, energy and valuable materials from sewage, while adequately abating pathogens, heavy metals and trace organics. Electrical energy recovery from anaerobic digestion of the organics present in sewage and kitchen waste (KW) has a value of 4.0 per inhabitant equivalent (IE) per year. In addition to sewerage improvements and water conservation, prerequisites include an advanced physico-chemical and/or biological concentration step at the entry of the sewage treatment plant. In the side stream, the recovery of phosphorus and carbon-sequestrating biochar from the digested sludge and of nitrogen from the digestate has a value of 6.3IE-1 year-1. Alternatively, recovery of biogas and materials can occur directly on source-separated black water. In the main stream, partial nitritation and anammox oxidise residual nitrogen. Moreover, two serial heat pumps recover thermal energy, valued at 6.9IE-1 year-1, cooling the water by 5 degrees C, and membrane technologies recover potable water at 65IE-1 year-1. Interestingly, ZeroWasteWater is expected to be economically viable. Key steps are to incorporate water chain management into holistic urban planning and thus produce a cradle-to-cradle approach that society will find acceptable

Teacher change and development during training in social and emotional learning programs in Sweden

The paper presents the results from a thematic analysis of the process diaries of teachers involved in teacher training in social and emotional learning (SEL) in Sweden. Twentynine out of the 122 diaries available were analyzed until saturation was reached. The following themes and sub-themes were extracted: development (professional and personal, and classroom climate), and concomitants of development (need for collaboration and unease). The themes and sub-themes are related to theoretical aspects of specialised teacher education and to the debate in Sweden on how to proceed with SEL programs, and more generally with life skills programs. The results suggest that training generates both general teacher improvement and better implementation of SEL programs.peer-reviewe

Designing and Operating Safe and Secure Transit Systems: Assessing Current Practices in the United States and Abroad, MTI Report 04-05

Public transit systems around the world have for decades served as a principal venue for terrorist acts. Today, transit security is widely viewed as an important public policy issue and is a high priority at most large transit systems and at smaller systems operating in large metropolitan areas. Research on transit security in the United States has mushroomed since 9/11; this study is part of that new wave of research. This study contributes to our understanding of transit security by (1) reviewing and synthesizing nearly all previously published research on transit terrorism; (2) conducting detailed case studies of transit systems in London, Madrid, New York, Paris, Tokyo, and Washington, D.C.; (3) interviewing federal officials here in the United States responsible for overseeing transit security and transit industry representatives both here and abroad to learn about efforts to coordinate and finance transit security planning; and (4) surveying 113 of the largest transit operators in the United States. Our major findings include: (1) the threat of transit terrorism is probably not universal—most major attacks in the developed world have been on the largest systems in the largest cities; (2) this asymmetry of risk does not square with fiscal politics that seek to spread security funding among many jurisdictions; (3) transit managers are struggling to balance the costs and (uncertain) benefits of increased security against the costs and (certain) benefits of attracting passengers; (4) coordination and cooperation between security and transit agencies is improving, but far from complete; (5) enlisting passengers in surveillance has benefits, but fearful passengers may stop using public transit; (6) the role of crime prevention through environmental design in security planning is waxing; and (7) given the uncertain effectiveness of antitransit terrorism efforts, the most tangible benefits of increased attention to and spending on transit security may be a reduction in transit-related person and property crimes
