The main objective of this thesis is to explore the evolution of U.S. commercial domestic aircraft operations from 1991 to 2010 and describe the implications for future U.S. commercial domestic fleets. Using data collected from the U.S. Bureau of Transportation Statistics, we analyze 110 different aircraft types from 145 airlines operating U.S. commercial domestic service between 1991 and 2010. We classify the aircraft analyzed into four categories: turboprop, regional jet, narrow-body, and wide-body. Our study consists of three parts. First, we compare the four aircraft classes and explore trends in available seat miles, revenue passenger miles, load factor, aircraft departures, average stage length, aircraft utilization, seat capacity, daily departures per aircraft, aircraft ground time, and fuel burn. Second, we examine each of the aircraft classes in detail and provide insights on specific aircraft types. Finally, we compare product offerings from competing aircraft manufacturers in both the regional jet and narrow-body aircraft classes. The results indicate that more than 150 wide-body aircraft have been shifted from the U.S. commercial domestic market to international service while narrow-body stage lengths have increased 50% over the 20 year period analyzed. In addition, the introduction of more than 1,390 regional jets in the late 1990s and 2000s allowed airlines to expand hub operations and increase frequency on routes between major cities. A 10% decline in the turboprop fleet coupled with the lack of turboprop replacement aircraft in the 30 to 50-seat category suggest a potential for future reductions in air service to some smaller cities. Lastly, increasing fuel prices threaten the growth of the U.S. commercial domestic fleet in the upcoming decade and could potentially cause a significant number of aircraft to be no longer economically viable.

Повний текст джерелаFinding ways to objectively measure welfare within different sectors of the beef industry is necessary to continually improve cattle welfare from birth to slaughter. The first objective of Study 1 was to benchmark cow-calf producer perspectives on management strategies and challenges that ultimately affect cattle welfare on ranches in the United States. The second objective of Study 1 was to quantify how producers are marketing their calf crop, their priorities when selecting replacements, and if producers saw value in handling and care guidelines. A total of 1,414 responses from cow-calf producers in 44 states were collected through a survey done in partnership with BEEF Magazine. Thirty questions were asked of producers to gather demographic information, producers’ current handling and health management practices, and how they prioritized industry challenges. As well as establish at what age and through what avenue producers are marketing their calf crop, and gauge producer perspectives on a quality assessment outlining handling and care guidelines.
After analyses of producer responses, it was concluded that the frequency of management methods and decisions are impacted by age, operation size, location, and BQA certification. A higher percentage of respondents who were BQA certified used electronic eartags, followed by freeze branding. A higher percentage of respondents not BQA certified used basic eartags and hot branding. 74.5% of respondents were preconditioning their calf crop. A higher percentage of respondents were preconditioning their calf crop that were BQA certified, than those who were not BQA certified. The most important beef industry challenge identified was cow-calf health and the biggest challenge to producer’s own operation was identified as land availability/price. The most important animal health issues on producers’ operations were identified as Bovine Respiratory Disease, flies, Pinkeye, and reproductive health. By producer age, calf/neonate health was identified as the biggest challenge for respondents under the age of 30. Respondents age 55-70 responded that Veterinary Feed Directive (VFD)/regulations was more of a challenge than any other age group. Respondents with 50 head or less or more than 1,000 head more frequently retained their calf crop through finishing and respondents with 51 to 200 head and 201 head to 500 head more frequently backgrounded and then sold their calf crop. 13.5% of respondents answered yes, a veterinarian had offered to administer a drug for pain management when castrating or dehorning. Of those 13.5% who responded yes pain management had been offered, 54.55% of respondents chose to use a pain relief method. A higher percentage of producers that precondition also indicated that they use a pain relief method when castrating or dehorning more frequently, though it was still a low percentage. Overall, 46.3% of respondents saw value in handling and care guidelines and 54.9% of respondents saw value in a program including source and age verification, a vaccination plan, and handling and care guidelines. Respondents who were BQA certified, had a beef cow inventory of 501 to 1,000 head, who preconditioned their calves and backgrounded them before selling, and who lived in the West more frequently saw value in a quality assessment outlining handling and care guidelines.
The objective of Study 2 was to examine the effects of captive bolt length and breed type on post-stun leg activity in cattle. A total of 2,850 Holstein (HOL) and non-Holstein British/Continental bred (NHOL) steers and heifers were observed post-stunning at a large commercial slaughter facility. A penetrating pneumatic captive bolt stunner was used with three different bolt lengths: CON, 15.24 cm; MED, 16.51 cm; and LON, 17.78 cm. Hind limb kicking, forelimb activity, take away belt stops, carcass swing and number of knife sticks during exsanguination were recorded for each animal from video recording. Hind limb and forelimb kicks observed ranged from 0 to 25 and 0 to 8, respectively. A significant main effect of treatment, breed type and an interaction between treatment and breed type on hind limb activity was found. Analysis of post-stun hind limb and forelimb activity indicated that increasing pneumatic captive bolt length does not decrease post-stun leg activity but alternatively can increase kicking when using the longest bolt tested in particular types of cattle, i.e. Holsteins. Other parameters associated with the shackling and hoisting process were impacted by breed type as well. There was a higher percentage of cattle experiencing take away belt stops and carcass swing in HOL as compared with NHOL. (Abstract shortened by ProQuest.)

This paper employs the two-stage approach to evaluate the banks’ performance persistence, operational risk (core capital ratio, price cost margin) and the demand management policies (monetary policy, fiscal policy) to investigate the nonlinear uncertainty effect. In the first stage, the banks’ performance was evaluated by slack-based super efficiency model, which describes the operating characteristics of banks’ multiple input-outputs. The nonlinear effect was estimated by panel smooth transition regression model with the transition variable of the U.S. leading indicator. The empirical result shows four useful results when leading indicator (LI) is below the threshold (0.9593): Firstly, the banks will face the operating recession if they are trying to increase their monopoly power in the market. The recovery is ineffective, even though the LI is higher than the threshold. Secondly, maintaining the core capital ratio results in decline of operating performance, but the negative impact is gradually improved while the economy is picking up. Thirdly, decreasing the fund rate may help improve the banks'' performance. However, the contribution is diminished, inch by inch, as the LI exceed the threshold. Finally, the national debt leads to increasing the long-term interest rate, which may help improve banks’ efficiency; however, the contribution is ineffective when economic is warming up. The policy suggestions, in our research, are including: 1.Maintaining the competitive financial environment may help the banks to improve their operating efficiency. 2. Formulating the flexible leverage ratio, in the different business cycle stage, could reduce the negative effect on banks. 3. Ideating a solution to the banks’ dilemma such as the higher cost of outside financing while maintaining the leverage ratio during the depression. 4. When the economy is in rescission, the quantitative easing monetary (fiscal) policy lead to decreasing (increasing) the short (long) term interest, which may help improve the banks’ efficiency.
