ABSTRACT This study investigated the efficacy of using inoculation theory in developing students' skills in resisting pressures involved with drinking and driving situations. Inoculation theory stems from psychosocial investigations that have demonstrated that resistance to specific opposing arguments can be increased if subjects are familiar with these arguments. The study sample was coihprise...

Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein (Cas) system facilitates targeted genome editing in organisms. Despite high demand of this system, finding a reliable tool for the determination of specific target sites in large genomic data remained challenging. Here, we report SSFinder, a python script to perform high throughput detection of spec...

German small-and-medium sized software companies are facing an increasing pressure by their users with regards to usability expectations. While some software companies still heavily emphasize functional aspects of their products, others have identified the potential of usability to differentiate themselves. The study has an exploratory nature and employs cluster analysis to investigate response...

This paper describes the development of a simulation model to assess the inventory requirements of alternative rail sleeper replacement strategies. The main aim of the model is to determine the optimal replacement strategy, given replacement costs and resultant train operating cost benefits. We consider the replacement problem under the following assumptions: The time to failure under constant ...

Recent terrorist attacks carried out on behalf of ISIS on American and European soil by lone wolf attackers or sleeper cells remind us of the importance of understanding the dynamics of radicalization mediated by social media communication channels. In this paper, we shed light on the social media activity of a group of twenty-five thousand users whose association with ISIS online radical propa...

BACKGROUND Handgrip strength is used to identify sarcopenia and frailty phenotypes, being a potential predictor of mortality in older adults. However, uniformity is lacking in the reference values. This study aimed to describe handgrip strength values of older population aged ≥65 years in Portugal, considering the possible influence of anthropometric parameters. METHODS A cross-sectional stud...

The hypothesis that cues related to subjects' current concerns can control attentional and cognitive processes during sleeping and dreaming was examined by presenting concernand nonconcern-related verbal stimuli to seven male subjects during sleep Stages 2 and REM. The taped dream reports were judged for stimulus incorporation by two independent raters. The results revealed that concern stimuli...

Rapidly deployable wireless networks consist of mobile base stations and less powerful mobile hosts. The mobile base stations have to maintain wireless connectivity while on the move along pre-de ned paths. Physical obstructions and wireless range limitations may prevent a pair of mobile base stations from establishing a wireless link. We study situations of distance-constrained mobility, and f...

A numerical model to predict train induced vibrations is presented. The dynamic computation considers mutual interactions in vehicle/track coupled systems by means of a finite and discrete elements method. The rail defects and the case of out-of-round wheels are considered. The dynamic interaction between the wheel-sets and the rail is accomplished by using the non-linear Hertzian model with hy...
