William Mahone and the Confederate Command Style During the Siege of Petersburg, 1864-1865

William Mahone exemplified the audacity and adaptability acquired by southern commanders during the last year of the American Civil War. Mahone\u27s contribution to Confederate military operations during the siege of Petersburg, Virginia, from 1864-1865 played an important role in the Confederacy\u27s survival. During the siege, he was one of Lee\u27s most trusted and capable lieutenants. The findings of this study show that Mahone\u27s emergence as a superior divisional commander came about mainly because of his knowledge of the terrain surrounding Petersburg. This thesis discusses the way Mahone extended the life of the Confederacy. Four of Mahone\u27s engagements during the siege will be examined; additionally, I will explain how his knowledge and ability influenced Confederate successes during those engagements. Also discussed is Mahone\u27s place in the evolution of siege warfare and his contributions in the development of a limited offensive strategy. The primary sources used for this project include Mahone\u27s personal letters concerning his actions and the Official Records of the War of the Rebellion

Psychological testing in supervision of clinical pastoral training

Thesis (Ph.D.)--Boston UniversityThree trends in theological education today contribute to the significance of this study: the careful selection of students for theological schools; an increased interest in the close supervision of the student's personal growth. These appear to be the instigating factors underlying the extensive use of psychological testing being employed by theological schools. The purpose of this dissertation is to determine how extensively psychological testing is being used and what contributions testing can make to the supervision of students in clinical pastoral training (CPT). First an historical survey was made of the CPT movement with special reference to the Council for Clinical Training (CCT) and the Institute of Pastoral Care (IPC). The relationship to theological education was examined to gain perspective and see the context from which to focus more clearly on psychological testing in the supervisory process. The goals of CPT were examined and found to center around (1) the student's self-understanding, 2) the development of interpersonal and interprofessional relations, and 3) a pastoral identity with concomitant skills [TRUNCATED

Perceived Effectiveness of Audiographic Distance Education in Three Central Illinois High Schools

Audiographic conferencing is a distance education practice being used in schools. Audiographic conferencing utilizes hardware and software to provide interactive audio and data transmission between locations. This study was conducted to assess the perceived effectiveness of the components of audiographic distance education by teachers and students in three Central Illinois High Schools involved in utilizing audiographics as a delivery system in terms of hardware, software, teaching techniques, appropriateness of course content, delivery system, and student achievement. The study took place during the 1994-95, 1995-96 and 1996-97 school years utilizing a survey of a population of teachers and students involved in audiographic classes. Responses to the survey were received by 7 of the 7 teachers and 118 of the 128 students involved in audiographic classes. Teachers and students reported general satisfaction with audiographics by assigning the highest ratings (4 or 5) to most areas of the components of audiographic distance education identified in the research questions. Some students and teachers indicated lack of satisfaction with the hardware, teaching technique of interaction between student/teacher and between students and satisfaction with achievement by assigning it the lowest ratings (1 or 2). Eight-six percent of teachers and 33% of students assigned the highest ratings (4 or 5) to recommending continuation of the program of audiographics as a distance education delivery system. Recommendations as a result of the study included evaluating the audio systems at the schools involved for effectiveness; exploring applying the audiographic system to deliver the instruction over the Internet; providing in-service to audiographic instructors about teaching techniques; looking for alternate modes of assessment of student performance in audiographic classes; and continued systematic observation and data collection to determine whether to continue audiographic distance education

High temperature coarsening of Cr2Nb precipitates in Cu-8 Cr-4 Nb alloy

A new high-temperature-strength, high-conductivity Cu-Cr-Nb alloy with a CrNb ratio of 2:1 was developed to achieve improved performance and durability. The Cu-8 Cr4 Nb alloy studied has demonstrated remarkable thermal and microstructural stability after long exposures at temperatures up to 0.98 T(sub m). This stability was mainly attributed to the slow coarsening kinetics of the Cr2Nb precipitates present in the alloy. At all temperatures, the microstructure consists of a bimodal and sometimes trimodal distribution of strengthening Cr2Nb precipitates, depending on precipitation condition, i.e. from liquid or solid solution, and cooling rates. These precipitates remain in the same size range, i.e. large precipitates of approximately I pm, and small precipitates less dm 300 nm, and effectively pin the grain boundaries thus retaining a fine grain size of 2.7 micro-m after 100 h at 1323 K. (A relatively small number of Cr-rich and Nb-rich particles were also present.) This grain boundary pinning and sluggish coarsening of Cr2Nb particles explain the retention of good mechanical properties after prolonged holding at very high temperatures, e.g., 75% of the original hardness after aging for 100 h at 1273 K. Application of LSW-based coarsening models indicated that the coarsening kinetics of the large precipitates are most likely governed by grain boundary diffsion and, to a lesser extent, volume diffusion mechanisms

Analysis of Large Quasistatic Deformations of Inelastic Solids by a New Stress Based Finite Element Method

A new hybrid stress finite element algorithm suitable for analyses of large quasistatic deformation of inelastic solids is presented. Principal variables in the formulation are the nominal stress rate and spin. The finite element equations which result are discrete versions of the equations of compatibility and angular momentum balance. Consistent reformulation of the constitutive equation and accurate and stable time integration of the stress are discussed at length. Examples which bring out the feasibility and performance of the algorithm conclude the work

Changing Consumer Food Prices: A User's Guide to ERS Analyses

USDA's Economic Research Service (ERS) uses different economic models to estimate the impact of higher input prices on consumer food prices. The present study compares three ERS models. In the first two models, neither consumers nor food producers respond to market prices. We refer to these two models as short-run models. In the third model, both consumers and food producers respond to changing prices, and we refer to this model as a long-run model. Given published parameter estimates, we simulate the impact of a higher energy price on consumer food prices, and our empirical findings are consistent with our understanding of market responses. In the short run, we find that the full effect of an increase in the price of energy is fully (or nearly fully) passed on to consumers, because neither food producers nor consumers can immediately respond to changing prices. In the long run, however, the price response of food producers and consumers serves to mitigate the increase in consumer food prices.price-spread model, input-output model, variable-proportions model, food prices, energy prices, input prices, Demand and Price Analysis,

B662: Costs and Returns on Maine Broiler Farms

This bulletin, in addition to presenting some statistical data on the growth and development of the broiler industry in Maine, includes the results of a survey made in 1967 of a representative sample of Maine contract broiler growers. A sample of 180 out of the approximately 900 broiler farms in Maine was surveyed during the summer of 1967 to obtain operating results for 1966. From this sample, 103 farms supplied information that was analyzed in this study. The average Maine broiler farm in 1966 had 20,913 square feet of floor space, which was unoccupied for an average of 65 days during the year. The average farm started 105,166 birds and marketed 99,235 birds, of which 93 percent were broilers and 7 percent were roasters. Total land area was 90 acres per farm and very little land was used for cropland or for other livestock enterprises. Average cash receipts per farm were $10,097, average cash expenses were$4,322, and average net cash income was $5,775 per farm in 1966. Net cash income tended to become greater as the size of farm became larger, ranging from an average of$2,931 on the smallest farms to an average of $8,820 on the largest farms. Broiler payments received in 1966 averaged 45.4¢ per square foot of floor space and$95.70 per 1000 birds marketed.https://digitalcommons.library.umaine.edu/aes_bulletin/1031/thumbnail.jp
