Drake Passage summary report: Cruises on RRS "James Clark Ross", 1993-2000. Drake Passage repeat hydrography: WOCE Southern Repeat Section 1b - Elephant Island to Burdwood Bank.
No full textThis report documents five early cruises in the Drake Passage annual repeat series conducted by Southampton Oceanography Centre in collaboration with the British Antarctic Survey. The series began under the auspices of the World Ocean Circulation Experiment as southern repeat section SR1b with a SeaSoar (towed undulating profiler) occupation in 1992. We document cruises from 1993 (JR0a), 1994 (JR0b), 1996 (JR16), 1997 (JR27) and 2000 (JR47). The cruises were all hydrographic CTD sections across Drake Passage between Burdwood Bank and Elephant Island, comprising 30 stations. One cruise (JR27) was occupied at higher resolution with 52 stations; also additional chemical measurements were made. On two cruises (JR16 and JR27), a lowered acoustic Doppler current profiler (ADCP) was introduced to provide full-depth water velocity profiles. Other measurements (vessel-mounted ADCP, sample salinity, navigation, expendable athythermographs, etc.) are described in context
Deep boundary current disintegration in Drake Passage
No full textThe fate of a deep boundary current that originates in the Southeast Pacific and flows southward along the continental slope of South America is elucidated. The current transports poorly ventilated water of low salinity (a type of Pacific Deep Water; PDW), into Drake Passage. East of Drake Passage, the boundary current breaks into fresh anticyclonic eddies, nine examples of which were observed in mooring data from December 2009 to March 2012. The observed eddies appear to originate mainly from a topographic separation point close to 60°W, have typical diameters of 20–60 km and accompanying Rossby numbers of 0.1–0.3. These features are likely to be responsible for transporting PDW meridionally across the ACC, explaining the near-homogenization of Circumpolar Deep Water properties downstream of Drake Passage. This mechanism of boundary current breakdown may constitute an important process in the Southern Ocean overturning circulation
Immunogenicity of Staphylococcus Aureus Antigens Against Experimentally Induced Mastitis in the Mouse and Optimization of Antigen Production in Fermenter Culture
No full text69 leaves. Advisor: Dean HogansonCapsular antigens of "Staphylococcus aureus" Smith and 2-8 strains were evaluated for immunogenicity in mice. Cultural conditions necessary for maximum expression of the antigens were also defined. Actively growing "S. aureus" Smith strain culture was used to challenge lactating GF-1 strain mice which had been vaccinated with various capsule
antigen preparations. Capsule antigen production was evaluated using shaker flask and fermenter cultures. Immunogenicity evaluations using single vaccinations showed that semi-purified capsule preparations elicited a protective response against challenge. Mice vaccinated twice showed that oil and aluminum hydroxide adjuvanted capsule
antigens protected against challenge, but DDA (dimethyldioctadecylammonium bromide) adjuvanted capsule antigens resulted in more mastitis than non-vaccinated controls. Cultural evaluations showed that media high in nitrogen and
carbohydrate content and grown at pH 5.5 resulted in the greatest amount of capsule antigen production. Capsular antigens may be more useful in preventing "S. aureus" mastitis than whole cell preparations. Media containing high concentrations of nitrogen source and carbohydrate are necessary to obtain large amount of capsular antigen. A
culture pH of 5.5 promotes the production of additional antigens not found when grown at higher or lower pH levels

Control of Mode and Intermediate Water Mass Properties in Drake Passage by the Amundsen Sea Low
No full textThe evolution of the physical properties of Subantarctic Mode Water (SAMW) and Antarctic Intermediate Water (AAIW) in the Drake Passage region is examined on time scales down to intraseasonal, within the 1969–2009 period. Both SAMW and AAIW experience substantial interannual to interdecadal variability, significantly linked to the action of the Amundsen Sea low (ASL) in their formation areas. Observations suggest that the interdecadal freshening tendency evident in SAMW over the past three decades has recently abated, while AAIW has warmed significantly since the early 2000s. The two water masses have also experienced a substantial lightening since the start of the record. Examination of the mechanisms underpinning water mass property variability shows that SAMW characteristics are controlled predominantly by a combination of air–sea turbulent heat fluxes, cross-frontal Ekman transport of Antarctic surface waters, and the evaporation–precipitation balance in the Subantarctic zone of the southeast Pacific and Drake Passage, while AAIW properties reflect air–sea turbulent heat fluxes and sea ice formation in the Bellingshausen Sea. The recent interdecadal evolution of the ASL is consistent with both the dominance of the processes described here and the response of SAMW and AAIW on that time scale
From Military Express to Free Delivery: the Postal History of Des Moines, Iowa
No full textii, 359 leaves. Advisor: Walter R. HoufThe problem. The role of postal history on the urban frontier has not been adequately explored by urban historians. The inauguration of postal service in fledging Midwestern towns served to not only unite separated family and friends, to legitimize place names, and to introduce politics into communities, but through the mail towns were promoted, newspapers gathered the news, new businesses replenished their shelves, and politicians wooed the voters. A detailed examination of the first thirty years of postal service in Des Moines, Iowa, will help to determine how widespread the influence of the mail was on the urban frontier, and will reveal the continuous effort expended toward realizing
the goal of improved postal service.
Procedure. Daily newspapers and obscure Post Office Department reports constitute the basic sources for the small details that tell the story of postal service improvement. Therefore the main research of this study consisted of the reading of all available Des Moines newspapers published during the period, and searching out applicable
Iowa mail contract bid information in Post Office Department reports contained in the voluminous United States Congressional "serial set." Private papers of the postmasters and other politicians provided the political stories behind postmaster appointments.
Conclusions. The remarkable advance in postal service experienced by the city of Des Moines during the first thirty years of its existence
can be attributed to strategic location, energetic businessmen-postmasters, and a determined manipulation of the political process. In a narrower vein, the study shows that postal matters (delivery time, postal rates, postage stamps, stationery, and postcards) played a greater role in everyday life than urban historians have heretofore indicated. And surviving examples of early Des Moines covers (envelopes) and letters prove that postal efforts to unite the city with the greater American community succeeded.Author may be contacted for comments and/or questions at [email protected]
Transfer Pricing--Can It Effectively Be Applied To Computer Services?
No full text71 leaves. Advisor: David S. HabrThe problem. From a financial point of view, the
primary function of the data processing department is to maximize the benefit the firm receives from its data processing resources. Though such a goal may be generally accepted, it is not entirely clear how it is achieved. This thesis seeks to remedy this situation by applying transfer price
to computer services.
Procedure. The research procedure consisted of an
analysis of transfer price theory and its varied applications. Next, the most generally accepted methods of transfer price theory were applied to an actual computer processing site to determine if any were applicable.
Findings. Transfer pricing is most generally
applied in one of the following four alternatives: (1) market price, a price based on a competitive external market; (2) negotiated price, a price mutually agreed to by the parties involved; (3) marginal cost, a price based on costs that vary with output and; (4) full cost, price based on
variable and fixed costs of the supplying division. Three units of transfer were determined, batch processing, online processing and developmental. Given four objectives, transfer price must be equitable, reproducible,
understandable and return no profit or loss. Full cost approach was found to be the most applicable.
Recommendations. The transfer price system as developed herein be implemented in a test environment initially. Even though the full cost alternative appeared to be the "best," a hint of marginal cost was obvious. The marginal cost would be a horizontal line or a close approximation.
After a period of time, cost trends will substantiate the system or support the marginal cost approach
Learned Helpless to Mastery Orientation Transition Process
No full textv, 259 leaves. Advisor: S. Pike HallBackground: Individuals who explain their success and failure experience in the Mastery Oriented attributional pattern of ability and sufficient or insufficient effort, experience pride in their successes, feel they can repeat successful experiences, see a relationship between outcome and effort, and are willing to try achievement tasks again. Individuals who explain their
success and failure experience in the Learned Helpless attributional pattern attribute success to luck and ease of task, and failure to inability, experiencing shame in both their
success and failure experiences. They feel they cannot repeat success experiences or correct failure experiences. They do not see a relationship between outcome and effort; and to avoid negative emotional consequences, they are not willing to try achievement tasks again.
Because it is desirable to correct the debilitating consequence of lack of persistence and avoideance, the researcher looked at the causal factors that bring about a change in an individual from a state of Learned Helplessness to a state of Mastery Orientation by studying individuals who have experienced this change without experiencing intentional retraining strategies.
Methodology: In order to explore and/or discover the full breadth of the LH to MO change phenomena, the researcher chose to explore this change through the recollections of individuals revisiting experiences that occurred as a
consequence of simply going about their daily lives. The change phenomena, whatever they would eventually be found to be, were an enmeshed part of each participant's life story.
Therefore, the researcher chose to use the Naturalistic research methodology that provides for observation in the natural setting from which the data arises to create joint construction of reality.
Findings: Three patterns were found to be present across the participants: Pattern One: Accepting Person. Pattern Two: Critical Consciousness-Raising Event. Pattern Three: Sense of Responsibility.
Conclusions: Based on the findings it becomes evident that it is wise for advisors and professors in college settings to reevaluate their attitudes toward students and to recognize the
power of mutually respectful relationships in which students can feel safe and growth can occur. It would a1so be wise to set up classroom systems in which students can experience acceptance from their peers, learn to work cooperatively in noncompetitive environments, and have a place to practice new skills and ideas. It would also seem important to become involved in student's crisis circumstances and use them to teach responsibility and offer support and caring
An Analysis of the Leader Behaviors of Career-Bound and Place-Bound Public School Superintendents in Iowa
No full text165 leaves. Advisor: Dr. Richard LampshireTwo types of superintendents are defined in the literature. Place-bound superintendents are promoted from within their present systems; career-bound superintendents are elected from outside. This study was made to determine whether the two career types exhibit different leader behaviors.
The problem. The problem investigated was: Are there differences in either initiating structure or consideration behaviors between career-and place-bound superintendents?
Procedure. A Career Patterns Questionnaire was designed and administered to all Iowa public school superintendents. Based upon the returns from 418 (ninety-three percent) of them, two samples were drawn, one of each career type, and were stratified according to school district enrollment. The Leader Behavior Description Questionnaire was administered to selected administrative staff members of the 174 subject superintendents. Five variables were analyzed: years in present position; age at first superintendency; Structure score, Consideration score; and total LBDQ score.
Findings. Findings included:
1) Place-bound superintendents, compared to careerbound: a) had significantly longer terms in office; b} were significantly older in the largest and smallest districts when first attaining the superintendency; and c) were mildly higher in LBDQ scores, except in the next-to-smallest schools.
2) There were no significant differences in Structure, Consideration. or total LBDQ scores between the two career types.
3) Length of term in office was mildly negatively correlated with LBDQ scores. This negative correlation was stronger for place-bound men and for all structure scores.
4) Age at first superintendency was not strongly correlated with any of the leader behavior scores for either career type.
S} In the largest schools, 25.0 percent of superintendents were place-bound; in the smallest, 13.2 percent were place-bound.
6) Sixty-eight percent of all place-bound superintendents had been high school principals immediately before attaining their present superintendencies.
7) For all superintendents, Structure and Consideration scores were highly correlated.
8) Eighty percent of career-bound superintendents in the largest schools had previously been superintendents, whereas forty-six percent of career-bound superintendents in the smallest schools had previously been superintendents.
Conclusions. Conclusions included:
1) Place-bound superintendents wait longer for promotion than career-bound men, especially in the largest and smallest schools, and stay longer in their superintendencies.
2) The hypotheses of no differences in Initiating Structure or Consideration scores must be retained. 3) Total LBDQ scores are not significantly different between the two career types.
4) Length of term in office adversely affects administrative subordinates' perceptions of their superintendents' leader behaviors, especially Structure. This effect is accentuated by place-boundedness.
5) Age at first superintendency has no appreciable relationship to leader behavior scores. 6) Frequency of occurrence of place-boundedness is directly related to school district size. 7) The high school principalship is the main route to the superintendency for place-bound men.
8) Administrative staffs do not view Initiating Structure and Consideration as separate aspects of their leaders' behavior.
9) The smallest schools may serve as training grounds for career-bound superintendents.
Recommendations. Recommendations were:
1) This study should be replicated, designed so that a one-tailed test may be used, with ratings secured from board members and teachers to test for a halo effect among the administrative staffs of place-bound superintendents.
2) Superintendents, especially place-bound, should be aware that perceived levels of Initiating Structure and Consideration decline as their tenures increase.
J) Place-bound superintendents should consider moving after gaining experience in their home districts.
4) The superintendency in the smallest districts should be made more attractive to career-bound men, so that they stay longer
The Double-Vision of Imagination : An Appraisal of Surface and Substance in the Fiction of Henry James
No full text248 leaves. Advisor: Norman R. HaneThis study is concerned, primarily, with the faculty of the imagination, incidentally as a general concept, but chiefly in its application to the fictional and critical works
of Henry James. A number of these works have been consulted with the intention of deriving, and subsequently illustrating, a coherent inquiry into "the creative intelligence" as it fulfills its roles as a source of inspiration and a learning aid for the author, and as an ingredient of theme through which James urges his characters toward self-discovery and a wide
consciousness of the palpable and spiritual worlds outside themselves. Commensurate with this effort is the recognition (the implications of which are also shown) that the imagination, for James, was a double-chambered affair--one room containing the aesthetic "sense" and the other the capacity for a fine moral awareness--and that the "lucid reflector," the character most susceptible to enlightenment, must live simultaneously in both compartments.
The first chapter introduces and begins to trace the development of this dipolar imagination within one novel in particular, The Portrait of a Lady. This initial segment,
by enlisting a few philosophical assertions of
Immanuel Kant, Samuel Taylor Coleridge, and the psychologist, Carl G. Jung, also attempts to suggest the depth and breadth of the Jamesian purview of human nature and its potential for emotional and intellectual growth.
The second chapter concentrates upon the aesthetic stem of the imagination and, with evidence gathered from five novels and one long story--The American, The Tragic Muse,
Roderick Hudson, The Princess Casamassima, The Europeans and "The Aspern Papers"--examines the possible uses and limitations of an appreciation of beauty and a strong sense of
form and order among external appearances.
The third and final chapter incorporates analyses of six additional novels--The Sacred Fount, The Wings of the Dove, What Maisie Knew, The Spoils of Poynton, The Ambassadors
and The Golden Bowl--with the purpose of determining what constructive and/or destructive elements reside within the Jamesian characters who evince an operative familiarity with :"the moral sense." In conjunction with this investigation
of the imagination's second chamber, an attempt is made to describe, through example and proposition, the causes and effects of the creative synthesis whereby Henry James, through
his characters and through the painstaking exercise of his craft, unites the love of external beauty and formal harmony with a compassionate affirmation of inner meaning and human responsibility
