Description
The objective of this study was to investigate the generational differences among US commercial airline pilots regarding their attitudes toward safety. A survey was distributed to three different US airlines: one major commercial airline, one regional airline, and one charter airline. A total of 106 pilots participated in this study. The pilots were categorized into three groups of generations based on birth years: Baby Boomers: 1946-1964, Generation X: 1965-1980, and Generation Y: 1981-2000. Through the use of one-way Analysis of Variance (ANOVA), the results of the analyses found that there was no significant difference between the generations of pilots regarding safety attitudes. In the subcategory of self-confidence, the results indicated no significant differences between the different generations of pilots. However, in the subcategories of risk orientation and safety orientation, significant differences were detected among the three generations of pilots. Baby Boomers were found to have the lowest risk tolerance, while Generation Y had the highest. Conversely, Baby Boomers were found to have the highest safety orientation, with the lowest being that of Generation Y.

Description
The purpose of this study was to measure the effect of gendered communication on women's behavioral intentions regarding nonprofit and for-profit entrepreneurship. Women represent half of the U.S. workforce, but only about one third of all American entrepreneurs are women. Feminists have argued that because entrepreneurship is largely understood as a masculine activity, women — who are predominantly socialized to espouse a feminine gender role — are less likely to become entrepreneurs. Previous scholarship and the particular theoretical lens of social feminism suggest that communication about entrepreneurship that is congruent with a feminine gender role would lead to the recruitment of a greater number of women entrepreneurs. Findings of the current study, however, suggested the opposite, providing support for poststructuralist feminist theory. Women who viewed a feminine entrepreneurship recruiting brochure about entrepreneurship reported themselves to be more feminine and less likely to report intentions to become entrepreneurs than women who viewed a masculine entrepreneurship recruiting brochure. These findings suggested that feminine communication may prime women to think of themselves as feminine, which may then lead them to view themselves as not masculine enough to be entrepreneurs. The applications of these findings stretch beyond engaging more women in entrepreneurship and also extend to scholarship that investigates gender's effects on women's pursuit of other masculine careers, including those in science, technology, engineering, and mathematics. Until the larger discourse on entrepreneurship changes to be inclusive of femininity, it is unlikely that strategies that feminize entrepreneurial activity in controlled situations will have an effect on changing the patterns of women's entrepreneurial intentions.

Description
Multimodal presentations have been found to facilitate learning, however, may be a disadvantage for low spatial ability students if they require spatial visualization. This disadvantage stems from their limited capacity to spatially visualize and retain information from both text and diagrams for integration. Similarly, working memory capacity (WMC) likely plays a key role in a learner's ability to retain information presented to them via both modalities. The present study investigated whether or not the act of self-explaining helps resolve deficits in learning caused by individual differences in spatial ability, working memory capacity, and prior knowledge when learning with text, or text and diagrams. No interactions were found, but prior knowledge consistently predicted performance on like posttests. The author presents methodological and theoretical explanations as to the null results of the present study.

Description
Observational tutoring has been found to be an effective method for teaching a variety of subjects by reusing dialogue from previous successful tutoring sessions. While it has been shown content can be learned through observational tutoring it has yet to been examined if a secondary behavior such as goal-setting can be influenced. The present study investigated if observing virtual humans engaging in a tutoring session on rotational kinematics with embedded positive goal oriented dialogue would increase knowledge of the material and perpetuate a shift an observer's goal-orientation from performance avoidance goal orientation (PAVGO) to learning goal orientation (LGO). Learning gains were observed in pre to post test knowledge retention tests. Significant changes from pretest to posttest occurred across conditions for LGO. Additionally, significant changes from PAVGO pretest to posttest were observed in the control condition however PAVGO did not significantly change in the experimental condition.

Description
In 2004 the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, and Slovenia joined the European Union (EU) as part of the EU's greatest enlargement to date. These countries were followed by Bulgaria and Romania in 2007. One benefit of joining the EU was the freedom for residents in the new EU member states to migrate to western European nations, notably the United Kingdom (UK). A result of this new freedom was an increased need for air travel. The intersection of the expansion of the EU with the introduction of low-cost airline service was the topic addressed in this study. Yearly traffic statistics obtained from the UK Civil Aviation Authority were used to formulate a trend line of passenger volume growth from 1990 to 2003. Through a time series regression analysis, a confidence interval was calculated that established that, beginning with the year 2004, passenger volumes exceeded the probable margin of error, despite flat population growth. Low-cost carriers responded to these market conditions through the introduction of new flights across the region. These carriers modeled themselves after Southwest Airlines, a strategy that appeared to be more effective at meeting the needs of the post-accession travel boom. The result was a dramatic rise in both passenger volumes and low-cost airline routes in an east-west direction across the continent.

Description
The three most common errors related to communication during shift turnovers are during inspection, installation, and the minimum equipment list (MEL). Miscommunications during shift turnover could lead to a catastrophic disaster. Numerous accidents have occurred relating to shift turnover issues; therefore, the Federal Aviation Administration (FAA) has been studying this matter in order to avoid preventable miscommunication problems. It has also been suggested that communication skills be developed at 14 CFR Part 147 schools so that students can communicate effectively with others in their future field. In order to assess the communication issues of students at these schools, three investigative treatments were utilized to assess communication during shift turnover. The first treatment consisted of verbal communication only; the second treatment consisted of the use of a whiteboard and written report; and the third treatment consisted of the use of a template of a fire protection system diagram on a whiteboard along with a written report. This study involved 14 students from a community college in the southwest. Data collected focused on the confidence level of communicated information related to the assigned tasks within a given time period. Through the use of Analysis of Variance, the results of the analyses found that there was no significant difference between each treatment. The data sets for the team leaders and team members were separately analyzed while there appears to be an increase of ease of communication by the use of the whiteboard- indicating a need for further study- no significant differences were found between the three treatments. Discussion of possible causes as well as the need for future investigations is presented.

Description
The landscape of higher education is constantly evolving. Similar to a wave that washes ashore and transforms the shoreline, the same is occurring with higher education and its "shoreline". With the influx of technology and social media on college and university campuses, higher education institutions have had to grapple with whether or not to implement the technology (e.g. mobile devices) and the social mediums (e.g. Facebook, Twitter, YouTube) that accompany these technologies into the academic and social college experiences of the tech-savvy students enrolling in higher education institutions. Higher education's new shoreline is largely being produced by the new paradigms of technology and social media adopted by the Net Generation college student. The forces of the evolving nature of technology are having an enormous impact on higher education practitioners. The prolific transcendence of Smartphones, tablets, and social mediums and the expansion of broadband (e.g. Wi-Fi) are changing student expectations of how higher education practitioners engage, communicate, and connect with the Net Generation college student. The assumption that many higher education practitioners have of social media is that social media primarily consists of Facebook and Twitter. Arguably Facebook and Twitter comprise the primary social avenues students traverse when communicating with friends and family but additionally, these sites can also be utilized for academic and social purposes advantageous to colleges and universities in enhancing the college student experience. The purpose of this study is to understand and describe how the Net Generation college student uses social media in their academic and social college experiences. Through the use of a descriptive analysis, this action research study described how the Net Generation college student uses social media in their academic and social college student experiences.

Description
Assemblers and compilers provide feedback to a programmer in the form of error messages. These error messages become input to the debugging model of the programmer. For the programmer to fix an error, they should first locate the error in the program, understand what is causing that error, and finally resolve that error. Error messages play an important role in all three stages of fixing of errors. This thesis studies the effects of error messages in the context of teaching programming. Given an error message, this work investigates how it effects student’s way of 1) understanding the error, and 2) fixing the error. As part of the study, three error message types were developed – Default, Link and Example, to better understand the effects of error messages. The Default type provides an assembler-centric single line error message, the Link type provides a program-centric detailed error description with a hyperlink for more information, and the Example type provides a program centric detailed error description with a relevant example. All these error message types were developed for assembly language programming. A think aloud programming exercise was conducted as part of the study to capture the student programmer’s knowledge model. Different codes were developed to analyze the data collected as part of think aloud exercise. After transcribing, coding, and analyzing the data, it was found that the Link type of error message helped to fix the error in less time and with fewer steps. Among the three types, the Link type of error message also resulted in a significantly higher ratio of correct to incorrect steps taken by the programmer to fix the error.

Description
The Federal Flight Deck Officer (FFDO) program was mandated legislatively, as part of the Homeland Security Act of 2002. This study replicated earlier research that investigated pilots’ opinions of the current state of the FFDO program based on interviews. A Likert survey was created to allow simpler quantitative collection and analysis of opinions from large groups of pilots. A total of 43 airline pilots participated in this study. Responses to the Likert questions were compared with demographics, searching for significance through a Pearson chi-square test and frequencies were compared to earlier research findings. Significant chi-square results showed that those familiar with the program were more likely to agree the program should continue, it was effective, the screening and selection process of program applicants was adequate and the Federal Air Marshal Service’s management of the FFDO program was effective. Those with Military experience were more likely to disagree it was reasonable that FFDOs were required to pay for their own room and board during training or train on their own time. All those who shared an opinion agreed there should be a suggestion medium between FFDOs and their management. Unlike the prior study, all those familiar with the program agreed the weapons transportation and carriage procedures were adequate. Furthermore, all those who shared an opinion found the holster locking mechanism adequate, which was another reversal of opinion from the prior study. Similar to the prior study, pilots unanimously agree FFDOs were well trained and agreed that the program was effective and should continue.

Description
This thesis uses an aircraft aerodynamic model and propulsion data, which
represents a configuration similar to the Airbus A320, to perform trade studies to understand the weight and configuration effects of “out-of-trim” flight during takeoff, cruise, initial approach, and balked landing. It is found that flying an aircraft slightly above the angle of attack or pitch angle required for a trimmed, stabilized flight will cause the aircraft to lose speed rapidly. This effect is most noticeable for lighter aircraft and when one engine is rendered inoperative. In the event of an engine failure, if the pilot does not pitch the nose of the aircraft down quickly, speed losses are significant and potentially lead to stalling the aircraft. Even when the risk of stalling the aircraft is small, the implications on aircraft climb performance, obstacle clearance, and acceleration distances can still become problematic if the aircraft is not flown properly. When the aircraft is slightly above the trimmed angle of attack, the response is shown to closely follow the classical phugoid response where the aircraft will trade speed and altitude in an oscillatory manner. However, when the pitch angle is slightly above the trimmed condition, the aircraft does not show this phugoid pattern but instead just loses speed until it reaches a new stabilized trajectory, never having speed and altitude oscillate. In this event, the way a pilot should respond to both events is different and may cause confusion in the cockpit.
