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

Characterizing and following eddies in Drake Passage
No full textDrake Passage, the gap between South America and Antarctica, is a very energetic region, with strong currents and numerous eddies. These eddies are important for mixing waters across the main three fronts, and for affecting the biological productivity in the region. We use weekly maps of colour images, sea level anomaly and geostrophic velocities to characterize physical and biological activity in the region surrounding Drake Passage. In particular, we note that the largest eddy kinetic energy occurs to the east of the passage and is principally in the area bounded by the mean Subantarctic Front (SAF) and the mean Polar Front, whilst the biological productivity is highest in coastal regions, with the SAF acting as a clear southern boundary. In a number of cases, cyclonic eddies detected by altimetry also show a strong signature in ocean color. Regular XBT (eXpendable BathyThermograph) surveys provide information on sub-surface structure, confirming the altimetric identification of features and showing that they often contain water masses originating from the other side of the front

Attitudes Toward Women as Administrators in the Des Moines, Iowa Public Schools
No full text113 leaves. Advisor: Dr. Richard LampshireThe problem. In a profession dominated in numbers by women, few women find their way to the top. There are relatively few women in positions of leadership or administration in education. The purpose of this study was to determine the attitudes of the school related community toward women as administrators in the Des Moines, Iowa public schools.
Procedure. Five segments of the Des Moines community were the population for this study. Sample groups were taken from: (1) students in fourth, eighth, and eleventh grades;
(2) parents of children in these grades; (3) teaching faculty from the schools attended by these students; (4) present administrators in these buildings; (5) personnel from the College of Education, Drake University. Sample groups were given an opinionnaire prepared by the author and consisting of twelve statements which describe tasks, roles or characteristics of administrators. Results were tabulated and the data analyzed. Textual summaries and tables appear in numerical and percentage form for ease of interpretation.
Findings. The study shows that men and women are considered equally able at public relations, at having ambition and a career commitment, at having insight into the needs of people. Women are perceived as working as well under women as under men, as being able to satisfy the community in assuming principalship of a school. Men and women are viewed as being equally able to make decisions and to organize effectively. Males are believed to be better disciplinarians by parents, students and older teachers, not, however, by the majority of the teaching faculty nor by administrators. Women are considered to be more sensitive, taking things more personally than men. Most segments of the study believed that young girls need successful women as models to emulate, and most segments also do not perceive the Des Moines schools as having a particular problem of sex bias or discrimination.
Conclusion. The findings of this study, when viewed as a whole, do not show any consistent negative attitudes toward women as administrators in the Des Moines, Iowa public Schools. On most of the questions asked, men and women were regarded by the subjects as equally able to perform tasks of leedership
