African American women judges on courts of general and appellate jurisdictions: a descriptive analysis, 1995
Get PDFThis is a study on African American women judges who serve on the general and appellate courts. This study addresses four questions: who and where they serve?; what were the recruitment and selections processes that netted the majority of these judges?; what are their attitude and perceptions of gender related issues?; and what were the barriers of those seeking the judiciary? This descriptive analysis is presented as a case study. The analysis is based on data collected from the universe of African American women judges and a random sample of non-African American women judges on these court levels. African American women judges have served less than five years. They reached the bench through an informal selection process at a younger age than their judicial counterparts. They serve in large cities where they are usually the only African American woman on their court and/or court level. They are Democrats and prescribe towards a liberal ideology, yet they do not consider themselves feminists. The gender issue is important, but the race issue supersedes. The research found few differences between black and white women judge
An investigation of the perceptions of teachers regarding the role of principal leadership in the effective implementation of technology, 2004
Get PDFIn this study, the views of teachers were sought regarding elementary principals' leadership style and teachers' implementation of technology, related to the state required Intech program. Sixty participants responded to a Level of Technology survey (LoTi). Teachers' views of their level of technology implementation in the classroom were described, with statistically significant differences present between those teachers trained in Intech and those teachers who have not been trained in Intech. A multiple regression procedure revealed that consideration and grade level were significant predictors of current instructional practices. The model indicated that the lower the consideration score and the lower the grade level reported, the higher the score obtained on the current instructional practices variable. No statistically significant relationship was yielded between the state-required Intech program and teachers' reported use of technology, as measured by the Loti framework. The findings from this study add to the current body of knowledge in several ways. Elementary principals' leadership style was found to be related to implementation of technology in the classroom setting. In addition, teachers trained in the Intech model differed in their technology practices within the classroom setting. Practitioners and researchers alike may find the results of this study useful
Examining the female leader in Octavia Butler's dawn and Fledgling, 2011
Get PDFThis study examines the prototypical female leader as constructed by Octavia Butler in her science fiction novels, Dawn and Fledgling. The premise of the study relates to the protagonists capacity to undergo arduous tasks in extraordinary circumstances so that they can ultimately lead their people into a revolutionized society. Overcoming enormous obstacles, including the rejection of the very people they must lead, proves that both protagonists, Lilith Ilypo, in Dawn, and Shori Matthews, in Fledgling, are the women of the future, created to lead human beings into a brave new world. The study further examines Butlers portrayal of the othemesses that continue to plague societies, despite the societies higher evolution, and concludes that only through continuous compromise will the world become unified. Butler indicates that the onerous task of achieving this ultimate unification lies on the shoulders of women who will serve as, what I term, the futures female Adams
Complex sphingolipid involvement in the expression of CYP1A1 activity in 3-methylcholanthrene-exposed HEPG2 cells, 2001
No full textPolycyclic aromatic hydrocarbons (PAHs), complex organic molecules that are the by-products of carbon-based fuel combustion, are carcinogenic upon biotransformation in the body. Cytochrome P450 1A1 (CYP1A1) is part of the enzyme system primarily responsible for the metabolism and biotransformation of PAHs in humans. In HepG2 cells (a human hepatoma cell line), it has been established previously in this laboratory that 3-methylcholanthrene (MC), a PAH, induces CYP1A1 activity 20 to 30 fold over control values. Also in those studies, MCs ability to induce this activity was significantly reduced by compounds that inhibit the synthesis of complex sphingolipids. However, addition of the synthetic short-chain sphingolipid C2-ceramide after inducer and inhibitor treatment restored CYP1A1 inducibility. This produced the current laboratory hypothesis that complex sphingolipids are involved in the signal transduction pathway used by MC to induce CYP1A1 activity. This research investigated the role that sphingolipids play in the inducibility of CYP1A1 by MC. Initially, the induction of CYP1A1 was examined by MC as a transcriptional event in these cells. Western blot analysis was used to determine whether CYP1A1 protein amounts fluctuate with CYP1A1 activity per the treatments used. Further studies included quantitative real-time reverse transcriptase PCR to quantitate the amount of CYP1A1 mRNA that resulted from each treatment. It was found that the action of the inhibitor of sphingolipid synthesis seems to be dependent on the presence of a heavy metal. It was also found that C2-ceramide, the prototype complex sphingolipid used, causes synergistic induction of CYP1A1 enzyme activity and that this synergism apparently results from actions at the level of the gene. Thus, it can be concluded that complex sphingolipids are involved in the transcriptional regulation of CYP1A1 expression
