Do the benefits of transporting hazardous material by rail outweigh the costs and damage on the environment?
The following study into quantitative and ecological risk analysis of the transportation of hazardous chemicals by train across the United States. The study employs findings and conclusions made by former literature conducted over the effects of transporting hazardous material by rail and the environment. The study also analyses geographic data surrounding rail systems in the United States involved with transporting hazardous contents. Ecological features of these surroundings build towards probabilistic approximations of exposure to various spill cases the history of America’s rail system. This risk analysis integrated approximated cleanup expenses that accrued, effect of dispute on the distribution of soil, underground water, the contributions of yearly traffic, the rates of accidents, and deployed safety measures.
A number of factors influence the risk and scale of the criticality of the consequence of spilling hazardous material on the environment during transportation by rail. First, the difference in safety performance of the standard tank cabin layouts is a significant risk factor (Anand et al., 2006). The higher the difference in cabin miles among various hazardous materials, and the difference in yearly accident-induced spill rate. Second, in approximating the effect expenses, hazardous substances that dissolve less in water incur more soil and groundwater cleanup expenses due to longer remediation periods (Xie et al., 2012). Third, in approximating the evacuation expenses, hazardous material moved along routes with more populations incur more evacuation expenses. Lastly, scheduled delay expenses may range from 3 to 8% of the entire effects costs in contrast to from 76 to 88% of cleaning up hazardous substances spilled into the soil and groundwater (Spraggins, 2011).

Some of the identified reasons for this dramatic shift of roles is the increasing number of young, unmarried teen mothers, the HIV and AIDS pandemic which has wiped out most young parents leaving the children orphaned, the increasing number of divorce cases, child abuse, drugs and substance abuse to the extent of parents neglecting their children and even incarceration of the parents (Goodman and Silverstein, 2006).
Eighty thousand Americans are blind, due to glaucoma (4). A sizable number of glaucoma sufferers do not even know they have it. Regular screenings for glaucoma used to be highly encouraged, until scientists began to question whether the benefits were worth the risks of the screening.
How will these be used as a manager? How are they being implemented where one is currently employed? Management Issues Effectively Managing a Diverse Organization A. Brief Overview The concepts of managing and incorporating diversity have significantly influenced organizational performance.
This treatise explores the importance of open communication in establishing a healthy parental relationship. The process of conducting this research is commenced by a review of peer-reviewed, scholarly journals with topics focused on open communication. This treatise covers overlapping subject matters on communications which were consolidated by extracting the common denominator among these reviewed expositions.
An open-source software (OSS) is a kind of computer software which is in the form of source code. In the OSS, the source code, as well as rights that are commonly meant only for the copyright holders, can be acquired under the open-source license which allows the users to read, use, change, modify, and even distribute the software.
Open Access began during the 1990s, and since the year 2000, there have been new Open Access publishers coming online such as BioMedCentral, Public Library of Science, Hindawi and Bentham Open (Bjork, Welling, Laakso, Majlender, Hedlund, & Guonason, 2010, web).
Terrorism has highly been a negatively effective approach to the weak side involved in a conflict. Due to the groups’ small size and the secretive nature of the terrorist organizations, they give opponents unclear group to fight against or deter with its deeds (Burke & Cooper, 2008).
