Inventory of the Decapod Crustaceans (Crayfishes and Shrimps) of Arkansas with a Discussion of Their Habitats

The freshwater decapod crustaceans of Arkansas presently consist of two species of shrimps and 51 taxa of crayfishes divided into 47 species and four subspecies. The shrimps are represented by Macrobranchium ohione and Palaemonetes kadiakensis. The crayfish fauna is the largest of any state west of the Mississippi River reflecting the variety of habitats within Arkansas as a result of the geologic diversity in the state. The Ozark Plateaus and Ouachita provinces are dominated by the genus Orconectes, while in the Gulf Coastal Plain Procambarus is the most conspicuous group. Other crayfish stocks present include Cambarus, found predominantly in the Ozark Plateaus province, and Bouchardina, Cambarellus, Fallicambarus, and Faxonella which are largely restricted to the Coastal Plain. The crayfishes and shrimps live in a broad array of epigean lotic and lentic habitats. In addition, a troglobitic crayfish occupies limestone solution channels, and burrowing crayfishes inhabit the subsurface water table. General discussions of the taxonomy and geographic distributions of the genera are presented, including brief descriptions of habitats in Arkansas that are utilized by freshwater decapods. Only the conservation of a single species, the troglobitic crayfish Cambarus zophonastes, is of concern in the state

Moroccan transition strategies towards free trade with the EU in 2010

The general strategy is one of the liberalization of the economy and the government regulations that control it. Labor is exepected to be reallocated through free market mechanisms which encourage foreign investment. Concurrently a stratgey is being developed to supply the necessary human capital through a revaluationa and redirection of the educational system. Labor categories will experience significant shifts, but certain sectors may not shift adequately to meet demand. The analysis shows the misalignment of certain labor allocation strategies.There is a significant pent up demand in the country for European goods and services which will be substantially released with customs union. The challenge of the government is to develop globally competitive industries/companies which will find significant adavantage in free trade and be able to offset the increase in imports by a corresponding increase in exports. The government has identified some possible sectors for encouragement and assistance. A strategy for foreign investment in such sectors is being considered. Possible adjustments in strategy are outlined.

Effect of State E-Verify Laws on H2A Program Utilization

The United States enjoys a per-capita gross domestic product more than five times the size of Mexico (World Bank, 2015). Yet the immigration policies of the United States fail to recognize the incentives workers in Mexico have to immigrate, legally or otherwise, into the United States. The law alone fails to control the movement of people across a 1,900-mile land border. Immigration has contributed to the economic and cultural dynamism of the United States. In the short-run, it may create economic winners and losers, leading to domestic tension. After Congress debated and then rejected President George W. Bush’s immigration overhaul in 2007, state governments started adopting laws and rules targeting illegal immigrants. Many of those laws forced employers to use the electronic E-Verify system to check whether prospective hires were eligible to work in the United States. Typically, the primary goal was to bar illegal immigrants from the workforce. Additional goals included boosting the employment prospects and earnings of legal residents, and encouraging illegal immigrants to voluntarily leave markets governed by E-Verify requirements. Politicians focused particular attention on the U.S. agricultural industry, which is not surprising since U.S. Department of Agriculture surveys show roughly half the agricultural workforce is working in the country illegally. Farmers say they hire illegal workers because they cannot find enough U.S. workers to harvest labor-intensive produce and livestock. Supporters of the E-Verify law in Georgia said one of their policy goals was to encourage farmers to secure legal, foreign laborers through the federally run H2A visa program. The H2A system allows growers facing domestic labor shortages to import foreign laborers for up to 10 months, though the program is bureaucratically cumbersome and requires that cost-sensitive growers pay above-market wages. To determine whether E-Verify laws encourage H2A use, the author reviewed every state E-Verify law affecting the agricultural industry. After aggregating H2A usage data at the state level, the author conducted a fixed-effects regression that controls for years, monthly seasonal fluctuations, state effects, H2A wage costs, and the relative strength of a state’s E-Verify law. While there is anecdotal evidence that E-Verify laws may disrupt labor markets, there is little statistical evidence that state E-Verify laws cause farmers to increasingly rely on the H2A system. Surprisingly, there is statistical evidence that the strictest E-Verify laws may reduce H2A usage

A Technical, Musical, and Historical Analysis of Frederic Chopin’s Etudes, Op. 10

While learning the etudes I decided to write a paper discussing their musical and technical challenges that would serve as a guide in working through these challenges. This guide is intended for both performers of the etudes and teachers in helping their more gifted students

The oxidation of sulfur dioxide in a regenerative reactor

A novel dual-unit sulfuric acid converter is depicted that performs in cyclic operation in unsteady state. A mathematical model and IBM 1130 Computer program were developed to show the temperature and conversion profiles in commercial-sized vanadium oxide catalyst beds. In the catalytic oxidation of sulfur dioxide conversions of 95-97% were attained without benefit of conventional heat exchangers. A single exchanger operating in conjunction with the dual-unit system might attain conversions as high as 99%

The Interpretation of the Olivet Discourse by Ellen G. White and her Contemporaries

The purpose of this thesis is to define the methods Ellen White employed in interpreting the Olivet Discourse; and further to review the exposition that grew out of these methods. Once these methods have been identified and the exposition defined, these will then be contrasted and compared with other writers. These writers have been classified under four headings: the Millerite lecturers; Seventh-day Adventist writers; non-Seventh-day Adventist authors whose books were in her libraries, and finally non-Seventh-day Adventist authors whose books were not in her libraries
