The acquisition of energy resources is a necessity to power the nation, fuel its economy, and support its people. The introduction of hydraulic fracturing has created an energy boom in North America, revolutionizing the supply and demand of energy for the country. This article explores the fundamentals of the hydraulic fracturing process, the economic benefits, and the corresponding environmental impact of the practice. Furthermore, the article discusses the regulation of fracking on a local and federal level and offers a practical, balanced approach to limit the adverse environmental impacts of hydraulic fracturing while retaining its economic advantages.  相似文献

This study discusses different media strategies followed by the Islamic State in Iraq and Syria (ISIS). In particular, the study attempts to understand the way ISIS’s video game that is called “Salil al-Sawarem” (The Clanging of the Swords) has been received by the online Arab public. The article argues that the goal behind making and releasing the video game was to gain publicity and attract attention to the group, and the general target was young people. The main technique used by ISIS is what I call “troll, flame, and engage.” The results indicate that the majority of comments are against ISIS and its game, though most of the top ten videos are favorable towards the group. The sectarian dimension between Sunnis and Shiites is highly emphasized in the online exchanges, and YouTube remains an active social networking site that is used by ISIS followers and sympathizers to promote the group and recruit others.  相似文献

The article examines and analyzes the nature of deviations and distortions in the VAT system in Bangladesh. The article argues that the Bangladesh VAT introduced in 1991—with a view to maximize tax revenue by broadening tax base and curbing tax evasion while simplifying the process—has deviated significantly from standard and international best practices. It further argues that most of the deviations have their roots in the excise system of taxation that VAT has replaced and, while some of them produce ad hoc benefits in terms of generating revenue and easing compliance, most of them, besides eroding the coherence of the tax system, defeat the core principle of VAT—self assessment. The article concludes that if the process of adulterating VAT with so many ingenious adaptations and deviations is allowed to continue, the objective of VAT to evolve as an efficient tool for maximizing revenue will remain elusive.  相似文献

A utility-maximizing model of judicial behavior predicts that,all else equal, judges who have stronger preferences for publishingopinions, who have lighter workloads, or who are able to writepublishable decisions more efficiently are more likely to publishtheir decisions. Using federal district court judges' decisionsregarding the constitutionality of the Federal Sentencing Guidelines,this article presents empirical support for these predictions.Many judicial, institutional, and other characteristics areexamined that should be correlated with a judge's workload orwith a judge's taste for, or efficiency in, publishing opinions.These analyses find that, all else equal, judges who held priorpolitical positions, who received higher American Bar Association(ABA) ratings, who had lighter caseloads, who had longer tenures,who struck down the guidelines, or who had a greater chanceof promotion to a U.S. court of appeals were more likely topublish their decisions. In addition, judges' publication decisionswere significantly affected by the prior decisions of judgesin the same district, but little affected by those of judgesin other districts.  相似文献

This paper uses households' data from central region of Sudan to examine factors that affect infant and child mortality. The education of mother and father, community variables and household income per adult are used. For this purpose, a household survey was conducted to collect data on the variables of interest from a random sample withdrawn from the study population. 600 questionnaires were distributed to households in one province of the region (out of five) where there are seven localities. The data has been analyzed using different statistical and econometric methods, including ordinary least squares method. The ordinary least squares found that child mortality is inversely associated with household income per adult, community variables and parental education. The effect of mother's education is more significant than father's education, mother's age is also found to be the most important factor that influences child mortality.  相似文献
