Abstract:
The work examines noise barriers and evaluates their effectiveness when changing their geometry and shape. Noise barriers are one of the most effective and widely used methods of reducing noise caused by road and railway transport. The effectiveness of the barrier depends on the materials used in the construction, the barrier’s height, geometry, shape, and the acoustic properties of the additional elements installed on top of the barriers. The aim of the work is to review and analyze the scientific literature, which would allow to evaluate the dependence of the acoustic characteristics of nois

Abstract:
Studies have been implemented in the literature to enhance the safety of traffic barriers by identification of the contributory factors to those crashes. However, almost all those past studies are subject to potential pitfalls of just answering the cause-and-effect question by traditional statistical methods, which fail to account for possible endogeneity. Modeling traffic barrier crash severity with traditional statistical methods might be biased as many parameters such as barrier’s types is endogenous to unseen factors including policy makers’ decisions in allocating those barriers.

Abstract:
Abstract Two main elements are essential in terms of road traffic safety. The first element is accident prevention and the second is the minimization of accident severity once a crash has occurred. Concrete safety barriers have very good anti-collision performance against roadside obstacles, relatively modest construction and maintenance costs, and low dynamic deflection and therefore are widely used in tunnels. Thanks to their characteristic redirective profile these barriers can redirect errant vehicles into their original lane after collisions. However insufficient research has been done fo

Abstract:
In most mega cities roadside barriers are used to protect receivers from noise pollution during recent years. Median noise barriers, like roadside noise barriers, can be employed to reduce the impact of traffic on roadside communities. In this study, a 2D boundary element method (BEM) is used to predict the insertion loss of different barrier models. It was shown that the performance of a median barrier along with a roadside barrier is affected if another road side barrier will be erected. However, it is possible to apply some new barrier designs to decline the negative effect of the extra roa

Background: The successful implementation of evidence-based practices (EBPs) in real-world settings requires an adaptive approach and ongoing process evaluation and tailoring. Although conducting a needs assessment during the preparation phase of implementation is beneficial, it is challenging to predict all barriers to EBP implementation that may arise over the course of implementation and sustainment.

Abstract:
Gay men may not be physically active at recommended levels to achieve health benefits. Thus, a need exists to identify general (i.e., common across populations) and population-specific barriers that hinder or stop gay men from participating in physical activity (PA). Salient barriers may be identified through the extent each barrier limits PA (i.e., barrier limitation) and the level of one’s confidence to overcome barriers and engage in PA (i.e., self-regulatory efficacy). The purposes of this study were to (1) provide a description of general and population-specific barriers to PA among suffi

"Barriers to Closure" was a series of narratives specifically focusing on reoccurring thoughts, fears and anxieties within the artist's life. Instilled when he was younger, these anxieties were never resolved, thus creating additional fears as he grew into adolescence. Eventually they transformed into an intricate obstacle causing resolution to be a difficult task.These narratives are presented in thick bronze frames which constrain the content into a limited space. The pieces are purposefully small due to the artist's personal restriction of revealing what needs to be seen. Therefore, the vie

While this may seem like a long time, it represents a rapid and radical change in construction terms.

Abstract:
Unlike previous empirical studies that focus on barriers to entry in international trade, we focus on barriers to exit as measured by passport costs for a cross-section of countries. We test four common theories on the determinants of such exit barriers and find that macroeconomic and brain-drain explanations do explain high barriers to exit. However, institutional and cultural hypotheses do not appear to be empirically robust explanations of such high barriers. Our findings hold when applying instrumental variables, changes in specification, and changes in cross-country periods.
