This paper introduces a parameter-free clustering-based approach to detecting critical traffic road segments in urban areas, i.e., of spatially prolonged and high accident risk. In addition, it proposes novel domain-specific criterion for evaluating the clustering results, which promotes stability results through time inter-period spatial collocation, penalizes size selected clusters. To illust...

Analysis of fatality automobile accident data can be challenging in rural areas where a relatively small number of such accidents occurs on specific sections of highways. Combining crash data from the Fatality Analysis Reporting System (FARS) and highway networks and design specifications from the Oklahoma Department of Transportation (ODOT), this article employs Poisson regression analysis to ...

piratory failure may require mechanical ventilation to maintain oxygenation. Persistent hypoxemia may entail additional treatments, such as inhaled nitric oxide or high-frequency oscillation, but these treatments are not universally available. In contrast, ventilation in the prone position, first recommended in 1974, can be readily implemented in any intensive care unit (ICU), and clinicians sh...

Although several studies have used logit or probit models and their variants to fit data of accident severity on roadway segments, few have investigated accident severity at a railroad grade crossing (RGC). Compared to accident risk analysis in terms of accident frequency and severity of a highway system, investigation of the factors contributing to traffic accidents at an RGC may be more compl...

This paper describes the analysis of fatal accidents of Indian coal mines from April 1989 to March 1998. It is found that Indian mines have considerably higher accident and fatality rates compared to those in USA and South Africa, respectively. While open cast mines are generally known to be safer than underground mines, the Indian open cast mines are shown to be at least as hazardous to the wo...

People often claim they cannot remember, and other people often doubt those claims. For example, during his 2007 trial, Vice-Presidential Chief of Staff I. Lewis ‘‘Scooter’’ Libby claimed that he could not remember mentioning the identity of a Central Intelligence Agency employee to other government officials or reporters. Jurors found it difficult to believe that Libby could have forgotten hav...

Protein aggregation is being found to be associated with an increasing number of human diseases. Aggregation can lead to a loss of function (lack of active protein) or to a toxic gain of function (cytotoxicity associated with protein aggregates). Although potentially harmful, protein sequences predisposed to aggregation seem to be ubiquitous in all kingdoms of life, which suggests an evolutiona...

S100 proteins are small dimeric calcium-binding proteins which control cell cycle, growth and differentiation via interactions with different target proteins. Intrinsic disorder is a hallmark among many signaling proteins and S100 proteins have been proposed to contain disorder-prone regions. Interestingly, some S100 proteins also form amyloids: S100A8/A9 forms fibrils in prostatic inclusions a...

Abstract There is little empirical evidence on the predictive value of safety culture assessments (SCAs) in relation to how accident‐prone an organisation might be. Recently, Antonsen not just demonstrated a quantitative SCA mispredicted future outcomes, but actually showed inverse relationship between assessment and subsequent critical incident investigation findings. To add our understanding,...
