The Success Factors in Male-Dominant Fields : The Case of Women in the U.S.Mänttäri, Annina January 2009 (has links)
Nearly a centennial after the granted women’s suffrage in the United States, almost 40 yearsfrom the start of the 70’s women’s right’s movements women have shown that they canobtain same level in education as men can and graduate with competitive skills as men.However, according to statistics that is when the equality seems to loose its balance. Despitethis there are women in this “Yes We Can”-era of where a former First Lady was verycompetitive in a Presidential Race, that with certain success factors compete effectively invarious male-dominant fields.

Transcriptional regulation of sex-dependently expressed renal organic anion transporter 1 and 3 / Transkriptionelle Regulation der geschlechtsabhängig exprimierten Organischen-Anionen-Transporter 1 und 3 in den NierenWegner, Waja 29 January 2013 (has links)
Organische-Anionen-Transporter (OATs) sind maßgeblich an der Ausscheidung von körpereigenen und körperfremden Substanzen über die Niere beteiligt. In Ratten, einem häufig verwendeten Tiermodell in präklinischen Studien, ist bekannt, dass die basolateral lokalisierten Organischen-Anionen-Transporter 1 (Oat1) und 3 (Oat3) in männlichen Tieren stärker und darüber hinaus Testosteron abhängig exprimiert werden. Beide Transporter sind an der Ausscheidung von organischen Anionen, einschließlich negativ geladener Medikamente wie zum Beispiel Adefovir, Furosemid oder Penicillin, beteiligt.
In den menschlichen Nieren zählen der OAT1 und der OAT3 zu den klinisch relevanten Transportern, deren Funktionen im Laufe neuer Medikamentenentwicklung berücksichtigt werden sollten. Für das Antibiotikum Penicillin wurde bei Frauen ein vermehrtes Auftreten von Nebenwirkungen im Vergleich zu Männern gezeigt. Dieses erhöhte Risiko könnte möglicher Weise auf einer geschlechtsabhängigen Expression des OAT1 und OAT3 zurückzuführen sein.
Ziel der vorliegenden Arbeit war es, den molekularen Mechanismus, der für die höhere Oat1 und Oat3 Expression in den männlichen Rattennieren verantwortlich ist, zu identifizieren.
Mit Hilfe von Luciferase assays wurde die Aktivierung von Ratten und menschlichen Oat1/OAT1 und Oat3/OAT3 Promotoren untersucht. Hierzu wurden zunächst Oat1/OAT1 und Oat3/OAT3 Promotorkonstrukte generiert, welche unterschiedlich lange Promotorregionen enthielten, und diese anschließend transient in OK oder LLC-PK1 Zellen transfiziert. Mittels Co-Transfektion potentieller transkriptioneller Regulatoren konnte deren Einfluss auf die Promotoraktivität von Oat1/OAT1 und Oat3/OAT3 untersucht werden.
Zur Identifikation geschlechtsabhängig exprimierter Gene in der proximalen Tubuluszelle der Rattennieren wurden von vier männlichen und vier weiblichen Tieren je eine Niere präpariert und deren RNA mit Hilfe eines microarrays und real-time PCR analysiert.
Im Rahmen dieser Arbeit konnte gezeigt werden, dass die bereits bekannte männlich dominierende Expression von Oat1 und Oat3 in Rattennieren nicht durch den klassischen Testosteron/Androgenrezeptor vermittelten, transkriptionellen Mechanismus reguliert wird. Vergleichbar zu den Ratten Oat1 und Oat3, zeigten auch die menschlichen OAT1 und OAT3 Promotoren keine Aktivierung durch den Testosteron/Androgenrezeptor-Komplex.
Während der Suche nach geschlechtsabhängig exprimierter transkriptioneller Regulatoren in der Rattenniere, konnte die Expression des Transkriptionsfaktors B-cell CLL/ lymphoma 6 (BCL6) erstmalig als männlich dominierend identifiziert werden. Die bereits bekannten Aktivatoren der Oats/OATs Expression, hepatocyte nuclear factor 1α (HNF1α), HNF1β und HNF4α zeigten keine geschlechtsabhängige Expression. Zudem konnte gezeigt werden, dass BCL6 die Promotoren der Ratten und menschlichen Oat1/OAT1 und Oat3/OAT3 aktiviert. Die BCL6-vermittelte Aktivierung von Oat1/OAT1 und Oat3/OAT3 erfolgt nicht über die bislang vorhergesagten BCL6-Bindungsstellen, aber möglicher Weise über Protein-Protein Interaktionen mit den Transkriptionsfaktoren HNF1 oder cAMP response element binding protein (CREB).
Zusammenfassend konnte gezeigt werden, dass der Transkriptionsfaktor BCL6 einen vielversprechenden Regulator der geschlechtsabhängigen Expression von Oat1 und Oat3 in Ratten darstellt. Es ist anzunehmen, dass BCL6 ebenso die humane OAT1 und OAT3 Expression reguliert.

Female Coaches’ Experiences of the Barriers and Strategies to Advancing as Elite Coaches in Swedish HandballPersson, Gabriella January 2024 (has links)
The present study aimed to (1) examine whether there is an underrepresentation of educated female coaches in Swedish handball and (2) highlight the barriers that contribute to the underrepresentation of female coaches as well as the strategies that can facilitate female involvement in a male-dominated culture, by starting from the feminist theory. A mixed methods methodology with a combination of quantitive descriptive analysis and qualitative semi-structured interviews was utilized. The quantitative analysis included 4010 coaches (1710 women and 2300 men) and showed a clear underrepresentation of educated female elite coaches (17%). The qualitative semi-structured interviews included 6 female coaches between the age of 28 and 59 (M=40.2, SD=11.6) who have all completed the Swedish Handball Federations coach education training level 5 and 6, which is aimed to senior and elite coaches. The results showed that female coaches experienced three general categories of barriers (1) the organizational system (e.g., the recruitment process); (2) external life factors (e.g., economic conditions) and (3) lack of enviromental support (e.g., psychological safety and trust). In addition, the result demonstrated that a two-dimensional approach: organizational and individual, is needed to deal with the perceived barriers. Future research should place emphasis on the experiences of female coaches at the sub-elite level and to ensure interventions are implemented and evaluated to ensure appropriate strategies can be utilized to keep and advance women in coaching at the sub-elite through to the elite level.

RECOGNIZING HER CHARACTERISTICS AS A LEADER: AN EXAMINATION OF THE SELF-ASSESSMENT OF WOMEN LEADERS AS SHAPED BY SOCIAL IDENTITY THEORY AND THE CONCEPT OF DOUBLE CONSCIOUSNESSGregory, John C 01 January 2017 (has links)
Women leaders are grossly underrepresented in police and Army organizations and relevant research suggests that women face the most significant challenges in reaching leadership positions in male dominant organizations. Although there have been recent policy changes to increase opportunities for women in police and Army organizations, women are still barely represented in senior command and primary staff positions in police and Army organizations. When women are underrepresented, particularly at the most senior ranks, there are implications regarding cultural, structural, and attitudinal challenges that simply should not still exist in these organizations. Using qualitative methods, this study examined the experiences of women leaders, specifically senior leaders, in selected police departments and representative Army commands and staff support agencies. Specifically, the study explored the characteristics of effective women leaders to assess the perceived group affiliation of these leaders as it relates to these leadership characteristics and personal assessments of their leadership capabilities. The findings revealed that women leaders possess a multitude of characteristics that have set the conditions for them to break through the “Glass Ceiling” despite the many challenges and obstacles that exist within male dominant organizations. The findings indicate that women leaders in police and Army organizations are care-givers, selfless servants, over-achievers, and great communicators. They identify themselves by their performance and leadership acumen as opposed to their gender, race, or any other demographic descriptors. The findings also suggest that women leaders continue to be faced with challenges and obstacles that make it extremely difficult for them to become senior leaders and navigate up the chain of command within their organization, which impacts their ability to influence policy changes that could address some of these cultural, structural, and attitudinal challenges.
