Jet Makers: The Aerospace Industry from 1945 to 1972

This volume presents the history of the American jet aircraft manufacturing industry from World War II to 1972, documenting the evolution of its technology and covering the intricacies of its management, economics, and relations with the government. A valuable contribution to general aviation history, it also provides a unique opportunity to study the dynamic of a major U.S. industry. Charles D. Bright traces the momentous revolution of the aerospace era from birth to maturity, using as a base the jet aircraft industry. He investigates all significant aspects: the coming-of-age of aviation during World War II, including global transportation and aerodynamics; the development of jets and missiles from the Truman era to the Vietnam War; the controlling influence of national military strategy; the U.S. Air Force and other government markets; the mechanics of government procurement—bidding, pricing, buying; difficulties in the commercial airliner business; the ordering of technology and the prevailing “design or die” philosophy; and different systems of production through the years. Special attention is given to major problems such as the industry’s need for diversification and the skyrocketing costs that threaten to make aerospace products uneconomical. The conventional economic concerns of entry into and exit from the industry are treated in depth. Bright focuses on the overall economic pattern, from the first demand for aerospace machines for military, space, and commercial uses to the failures of recent times as the industry entered recession and peacetime equilibrium. He tells of the desperate competition among giants of the industry, those companies on the frontiers of technology that manufactured fixed-wing aircraft of their own design. This is the group that bore the brunt of adaptation to the jet age: Boeing, Curtiss-Wright, Douglas, Fairchild, General Dynamics, Grumman, Lockheed, martin, McDonnell, North American Northrop, and Republic. Central to the story are the reasons for Americas leadership in the jet age: enterprising business managers, scientists, and engineers; the pressure of economics; and manifold competition brought on by economics; and manifold competition brought on by the cold war. Bright points to an industry that has responded to incredible demands and that has shown the strength to weather storms. This volume is illustrated with fifty-five photographs depicting the growth in aircraft technology from 1945 to 1972. As a unique blend of aeronautic, economic, business, and military history, it will fascinate not only those connected with aviation and the aerospace industry, but also those interested in the history of technology, business management, and government-military-business relations. The Jet Makers received Honorable Mention in the 1977 History Manuscript award competition of the American Institute of Aeronautics and Astronautics. Description Lt. Col Charles D. Bright (1921–2014) was World War II Eighth Army Air Force lead B-17 navigator and flew fighter jets during the Korean War.

Incorporating Critical Thinking Skills Into the Language Arts Curriculum, Particularly in the Field of Detective Fiction

In this age of accelerated change and continuing complexity, there is a widely-recognized need to incorporate critical thinking skills into all aspects of everyday life and not simply as an optional philosophy class at the post-secondary level of American education. Chapter One of this culminating project investigates the historical roots of critical thinking, with a brief investigation into the history of bow education in America (with slight digressions such as Alcott/Emerson\u27s Temple School and John Dewey\u27s Chicago experiments) has historically failed to foster the development of critical thinking skills in America\u27s students by its centuries old tradition of emphasizing rote memorization, passive learning, and social indoctrination. Chapter Two discusses how the realization of the importance of critical thinking skills has affected teacher education programs and has rekindled debates regarding the content versus process approach to including critical thinking skills in the curriculum. This chapter also investigates the current renaissance regarding wait-time and the importance of cooperative learning in the classroom. Echoing Ralph Waldo Emerson\u27s :sentiments regarding education, Chapter Three discusses techniques to foster creative and critical reading skills in the high school student as well as critical thinking skills. Included in this chapter are lateral thinking puzzles, word games, and exercises to stimulate critical thinking. Chapter Four investigates the application of critical thinking exercises into a discussion of one of the most popular literary genres, detective fiction. This chapter also provides a transcript of the actual implementation of this approach in a Detective Fiction class at Saint Francis Borgia Regional High School in Washington, Missouri. Chapter Five reiterates the guiding principles of the Center for Critical Thinking and Moral Critique and how they apply to the inclusion of critical thinking skills into the language arts curriculum, specifically in the field of detective fiction

The Effects of Allium Sativum and Zingiber Officinale Extracts on Shigella Dysenteriae Isolated from Ready-To-Eat Fried Chicken Sold in Ihiala L.G.A, Anambra State

A number of reports have shown that foods vended on streets including fast foods meant for immediate consumption can have high incidence of pathogenic bacteria which can pose serious public health problems to the consumers and may result to different disease conditions. This study was undertaken to evaluate the effects of Allium sativum and Zingiber officinale seed extracts on Shigella dysenteriae isolated from ready-to-eat fried chicken sold in Ihiala L.G.A., Anambra State. A total of 21 samples were collected from street hawkers (9 samples) and fast foods (12 samples) joints and plated on Salmonella Shigella Agar (SSA) using pour plated method at appropriate growth conditions. The bacterial isolate was characterized and identified using colonial descriptions and biochemical reactions. The phytochemical constituents of the extracts of Allium sativum and Zingiber officinale were determined quantitatively using spectrophotometric method. Tube dilution method was used to determine the Minimal Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) using double-fold serial dilutions at concentrations 25mg/ml to 400mg/ml. The phytochemical analysis of Allium sativum and Zingiber officinale extracts revealed the presence of alkaloids, saponins, flavonoids, tannins, phenolics, steroids and cardiac glycosides. The ethanolic extracts of both plants showed more activity (9.00 mm, 10.70 mm) than their aqueous extracts (7.30 mm, 7.70 mm) and their activity differed significantly (p< 0.05) from that of the ciprofloxacin (21.30 mm). The MICs (200 mg/ml, 400 mg/ml; 200 mg/ml, 400 mg/ml) and MBCs (400 mg/ml, Nil; 400 mg/ml, Nil) values revealed the inhibitory activities of ethanolic and aqueous extracts of Allium sativum and Zingiber officinale and cidal activities of their ethanolic extracts. The study recommends personal and environmental hygiene as preventive measures against bacterial contamination of foods and suggests that Allium sativum and Zingiber officinale could be used as alternative therapy for diseases associated with Shigella dysenteriae

Effects of Inflation Targeting Policy on Inflation Rates and Gross Domestic Product in Ghana

Inflation targeting has been widely adopted in both developed and developing economies. The Bank of Ghana (BOG) formally adopted an inflation targeting regime as a major monetary policy framework in May 2007, becoming the second African country to do so after South Africa. This research paper sought to investigate the effect of inflation targeting policy on inflation rates and gross domestic product. The research adopted the quantitative method by comparing the effect of inflation targeting policy on inflation rates and gross domestic product in the pre inflation targeting period (2000-2006) and the post inflation targeting period (2007-2013). The resultsrevealed that there was a significant difference between the mean inflation rates for the two periods. The inflation rate for the post inflation targeting period is significantly less than the pre-inflation targeting period. It was also revealed that inflation targeting did not have a statistically significant effect on economic growth in Ghana. The study concluded that policy makers are encouraged to explore other policy alternative including inflation targeting regime to maximize production in the economy. Keywords: Inflation Targeting Policy, Inflation Rates, Gross Domestic Produc

Molecular Characterization of Enteroxigenicity Profiles of Enteric Bacteria Isolated from Chicken Feeds

This study focused on molecular characterization of enterotoxigenicity profiles of enteric bacteria isolated from different brands of commercially produced chicken feeds sold in Anambra State. A total of 1,536 different chicken feed samples (starter, growers, finisher and layers) were collected from the consumers, retailers and wholesalers and screened for the presence of enteric bacteria using pour plate technique. The isolates were characterized and identified using their colony descriptions, biochemical and molecular characteristics. Presence of enterotoxins among the isolates was detected using Polymerase Chain Reaction (PCR) amplification of Ltx1 and Ltx2 genes. The result of this study revealed that Escherichia coli O157:H7 SS52 (EC), Salmonella serovar Typhimurium U288 (ST), Escherichia coli SEC470 (ES), Salmonella serovar Enteritidis YU39 (SY) and Salmonella serovar Enteritidis FM366 (SE) were isolated from the feed samples. The PCR results showed significant (P<0.05)  amplification of heat labile-1 (Ltx1) and heat labile-2(Ltx2) enterotoxin genes from EC, SE and ST of which EC showed most pronounced results. Thus, this study has shown that EC, ST, ES, EY and SE were detected from the studied chicken feed samples. The PCR results have revealed regions that contained heat labile enterotoxins, of which this region was most significant in EC.
