The Factors That Motivated American Ground Forces to Fight during Combat in Vietnam

Many people debate the policies of the United States government with respect to the conduct of the Vietnam War. The war was unpopular, at best, and many argued that our military should not have fought for South Vietnam. So, what compelled American ground forces to fight an atypical enemy? This thesis explores the motivational factors that influenced the military ground forces on a daily basis. Past research conducted on previous wars serves as the guideline for the methodology used. Combat narratives are the data sources and references to motivational factors by the authors are the data. As a whole, the narratives examined in this study reveal that primary group, combat survival, leadership, and duty were all significant motivating factors with none of the four heavily outweighing the others. Additionally, the narratives were categorized with respect to the characteristics of the author and the author\u27s combat experience. Of those categories, rank produced the most significant differences among motivational factors between groups. Leadership was a prominent motivating factor for officers while enlisted men fought for the good of the primary group and for combat survival

Entry-level student affairs administrators\u27 attitudes toward mental illness in college students.

Calls for universities to better serve college students with mental illness have been growing. While a considerable literature base supports Corrigan\u27s (2004) Social Cognitive Model of Mental Illness Stigma and the complex relationship among stereotypes, prejudice, and discrimination, limited research has been conducted examining university administrators on attitudes toward and knowledge of mental illness in college students. Participants of the current study were 206 entry-level student affairs professionals who completed an online, modified version of Becker, Martin, Wajeeh, Ward, and Shern\u27s (2002) Mental Illness Awareness Survey. Simultaneous regression was used to determine the significance of seven demographic variables (gender, age, ethnicity, level of education, type of university, university enrollment size, and years of experience) on five dependent variables: fear towards students with mental illness, confidence in ability to help students with mental illness, awareness of campus services, referrals to campus services, and knowledge of psychological disabilities. None of the five regression models were significant, likely due to a restriction of range in several independent variables in the entry-level study population. Three independent variables were significant at the p \u3c .01 level, including employment at a large university on fear, and years of experience and possession of a master\u27s degree on awareness of campus services. Compared to faculty responses on the instrument in an earlier study (Becker et al., 2002), entry-level student affairs professionals demonstrated a trend towards more positive attitudes and knowledge. Findings suggest that administrators desire continued education on mental illness in college students, particularly on disorders including schizophrenia, personality disorders, and paranoia, as well as disorders more commonly seen and/or on the rise in college students such as attention deficit hyperactivity disorder, eating disorders, bipolar disorder, and posttraumatic stress disorder. Recommendations are offered for graduate preparation programs and professional development workshops. Current study limitations and gaps in the literature can be addressed in future research using broader student affairs populations while examining disclosure in social media, factors related to effective referrals, and student perceptions of discrimination

Component Performance Investigation of J71 Type II Turbines: III - Overall Performance of J71 Type IIA Turbine

The over-all component performance characteristics of the J71 Type IIA three-stage turbine were experimentally determined over a range of speed and over-all turbine total-pressure ratio at inlet-air conditions af 35 inches of mercury absolute and 700 deg. R. The results are compared with those obtained for the J71 Type IIF turbine, which was previously investigated, the two turbines being designed for the same engine application. Geometrically the two turbines were much alike, having the same variation of annular flow area and the same number of blades for corresponding stator and rotor rows. However, the blade throat areas downstream of the first stator of the IIA turbine were smaller than those of the IIF; and the IIA blade profiles were curve-backed, whereas those of the IIF were straight-backed. The IIA turbine passed the equivalent design weight flow and had a brake internal efficiency of 0.880 at design equivalent speed and work output. A maximum efficiency of 0.896 occurred at 130 percent of design equivalent speed and a pressure ratio of 4.0. The turbine had a wide range of efficient operation. The IIA turbine had slightly higher efficiencies than the IIF turbine at comparable operating conditions. The fact that the IIA turbine obtained the design equivalent weight flow at the design equivalent operating point was probably a result of the decrease in the blading throat areas downstream of the first stator from those of the IIF turbine, which passed 105 percent of design weight flow at the corresponding operating point. The third stator row of blades of the IIA turbine choked at the design equivalent speed and at an over-all pressure ratio of 4.2; the third rotor choked at a pressure ratio of approximately 4.

Component Performance Investigation of J71 Experimental Turbine VII: Effect of First-stator Adjustment; Over-all Performance of J71-97 Turbine with 87-percent-design Stator Area

The performance results, as well as a compressor-turbine match point study based on a particular mode of engine operation, are compared with those previously obtained with the same turbine having first-stator areas 70, 95.6, and 132 percent of design. Maximum efficiencies for all turbine configurations were high, on the order of 87 to 89 percent. The efficiencies obtained at the match points for the 87-, 95.6-, and 132-percent turbines were slightly lower. No match point for the 70-percent turbine was obtained because, with first-stator areas less than 75.5 percent of design, the turbine would develop insufficient work to drive the compressor at the match point

Investigation of Turbines Suitable for Use in a Turbojet Engine with High Compressor Pressure Ratio and Low Compressor-tip Speed VII : Experimental Performance of Modified Two-stage Turbine

Modifying the original turbine by closing down the first-rotor throat area and shrouding the first and second rotors resulted in an over-all increase in in efficiency of 3.5 percentage points. At equivalent design work and speed the rating and aerodynamic efficiences of the modified turbine were 0.825 and 0.846, respectively. The maximum rating and erodynamic efficiencies were 0.875 and 0.906, respectively. A radial survey indicated improved firstively. A radial survey indicated improved first and second-stage efficiencies but showed that the effective throat areas of the second stator and rotor were too large

Component Performance Investigation of J71 Experimental Turbine VIII : Effect of First-stator Adjustment; Internal Flow Conditions of J71-97 Turbine with 70-percent-design Stator Area

Results of a survey investigation of the J71-97 experimental three-stage turbine equipped with a first-stator area 70 percent pf design are presented and compared with the turbine with a first-stator area 97 percent of design
