"The dynamic side of life": the emergence of Mary Coffin Ware Dennett as a radical sex educator
No full textIn 1915, Mary Ware Dennett wrote a significant yet little known sex education manual for her two sons entitled The Sex Side of Life, an Explanation for Young People.
In it, she defied convention by expressing her radical views about sexuality, first to her own two sons and later to the public. Dennett offered forthright and specific information about the physiological, scientific, moral and emotional aspects of sexuality at a time when sex education and sex educators, if they existed at all, typically attempted to repress or control sexuality, and education about it, rather than to inform.1 Many people
considered Dennett’s book radical because she challenged prevailing Victorian attitudes about sexuality, women and the transfer of culture. Additionally, she dared to express the view that sex was not just for procreation but was pleasurable. Dennett’s manual for her sons was copied and passed along to her son’s friends and to the children of her friends and colleagues. It was published in The Medical Review
of Reviews in 1918 and thousands of copies were distributed to institutions and individuals worldwide before she was arrested for sending obscenity through the mail in 1929. Fourteen years after publication, her arrest became a cause célèbre. Through narrative inquiry, the study researched Dennett’s transition from the private to the public side of life by looking at her cultural and intellectual heritage, personal life and the historical context of industrial capitalism. Dennett’s unequivocal conviction that all members of a truly democratic society have the right to know was
quite radical in its time. It is still radical today because implicit in that outlook is the belief that with knowledge, ordinary people have the ability and the responsibility to
chart their own course in life without control from those on top of the social hierarchy. Freire said, “A real humanist can be identified more by his trust in people, which engages him in their struggle, than by a thousand actions in their favor without that
trust.” Dennett was a true humanist, trusting in the ability of ordinary people. Nearly a century after publication, the lessons that surfaced from Dennett’s
transition from the private to the public side of life are still valid. The ability to actively engage with the world is critical for empowerment and active engagement can only occur with complete access to knowledge and information. Sexuality is part of the knowledge and comprehensive information that is necessary to experience The Dynamic Side of LifeEd.D.Includes bibliographical referencesby Lynn Ledere
Sociology's "One Law": Moral Statistics, Modernity, Religion, and German Nationalism in the Suicide Studies of Adolf Wagner and Alexander von Oettingen
No full textFrom the onset, moral statistics were influenced by religious discourse. During
the nineteenth century, Adolf Wagner discovered the "One Law" of sociology:
Protestants always kill themselves more often than Catholics. Deployed by his col
league, the Baltic nationalist theologian Alexander von Oettingen, it became a
moral-statistical plank in the modernity thesis and supported a Prussian master
narrative of history. Accordingly, it justified the unification of Germany according
to the small German model of a Kulturnation excluding Catholic Austria. This
interpretation, in turn, influenced subsequent generations of German sociologists,
who described modernity in idealist and spiritual terms. In this, they differed from
the more mechanistic and materialist theories of French sociologists, in particular

Gasströmungsverhalten in der tiefen Lunge unter superponierter Hochfrequenz Jet ventilation und Hochfrequenzoscillation
No full textAlthough superimposed high-frequency jet ventilation, SHFJV for short, has already achieved good clinical success, there has been little theoretical work on the method and no simulations have yet been performed using computational fluid dynamic simulations. SHFJV is an electrically controlled ventilation method in which a high-frequency gas flow is superimposed on a low-frequency gas flow. This creates a low-pressure plateau in addition to a high-pressure plateau, resulting in continuous delivery of small volumes of gas to the lungs during ventilation. Clinical studies have shown that this method leads to a faster recruitment of collapsed alveoli, thus improving patient oxygenation. In this work, a user-defined function (UDF) was created to control the application of ventilator-generated gas at the inlet and linked to a Navier Stokes Solver Suite. At the same time, a second function was used to mimic the physiological characteristics of the lungs, which allowed the gas flows in the lungs to be influenced. To calculate the flow patterns, the commercial software Fluent from ANSYS Inc. was used, and the Menter-SST-k-omega model was used as the turbulence model. An important part of working with simulation analysis is the validation of the system. Especially the functions that were programmed in the UDF had to be created and verified in single steps. The preliminary experiments were carried out on a straight tube model, while the main simulations were performed on several symmetric single-bifurcation geometries with up to eight lung tubes. The progression of results along these so-called generations allowed estimation of magnitudes for deeper lung regions. Parameters such as Womersley number and tidal volume also served as a basis for further analysis. In this diploma thesis, the influence of variable compliance on the flow behavior of two high-frequency ventilation techniques was investigated. Using the SST-k-omega tubulence model, the turbulent kinetic energies occurring in the bronchial system under variable lung compliance could be demonstrated.Obwohl die superponierte Hochfrequenzjetbeatmung, kurz SHFJV, bereits einen guten klinischen Erfolg verzeichnet, gibt es zu der Methode nur wenige theoretische Arbeiten und es wurden bisher auch keine Simulationen mittels nummerischer Strömungsmechanik durchgeführt. Bei der SHFJV handelt es sich um eine elektrisch kontrollierte Beatmungmethode bei der ein niederfrequenter Gasstrom von einem hochfrequenten Gasstrom überlagert wird. Dadurch entsteht zusätzlich zu einem Hochdruckplateau auch ein Niederdruckplateau, wodurch kontinuierlich kleine Gasvolumina während der Beatmung in die Lunge appliziert werden. Klinische Studien haben gezeigt, dass dieser Vorgang zu einer schnelleren Rekrutierung von kollabierten Lungenbläschen führt und damit die Oxygenierung bei Patienten verbessert wird. In dieser Arbeit wurde in einer benutzerdefinierte Funktion (UDF) eine Funktion erstellt, welche die Zufuhr des vom Beatmungsgerät erzeugten Gases am Einlass vorgibt und mit einer Navier Stokes Lösungssoftware verbunden. Gleichzeitig wurde mit einer zweiten Funktion die physiologischen Eigenschaften der Lunge immitiert, wodurch die Strömungen in der Lunge beeinflusst werden konnten. Um die Strömungsverläufe zu berechnen, wurde mit der kommerziellen Software Fluent von ANSYS Inc. gearbeitet. Das Menter-SST-k-omega Modell kam dabei als Turbulenzmodell zum Einsatz. Ein wichtiger Teil bei der Arbeit mit Simulationsanalysen ist die Validierung des Systems. Vor allem die Funktionen, die in der UDF programmiert wurden, mussten in einzelnen Schritten erstellt und kontrolliert werden. Die Vorversuche wurden an einem geraden Rohrmodell ausgeführt, während die Hauptsimulationen an mehreren symmetrischen Einzelverzweigungsgeometrien mit bis zu acht Lungenröhren durchgeführt wurde. Der Verlauf der Ergebnisse entlang dieser sogenannten Generationen ermöglichte eine Abschätzung der Größenordnungen für tiefere Lungenbereiche. Als Grundlage für weitere Analysen dienten auch Parameter wie die Womersley Zahl und das Tidalvolumen. Im Rahmen dieser Diplomarbeit wurde der Einfluss einer variablen Compliance auf das Strömungsverhalten zweier hochfrequenter Beatmungstechniken untersucht. Unter Verwendung des SST-k-omega Tubulenzmodells konnten auftretenden turbulenten kinetischen Energien im Bronchialsystem unter variabler Lungencompliance nachgewiesen werden
