Dutch Women In New Netherland And New York In The Seventeenth Century, Michael Eugene Gherke Dec 2001

Dutch Women In New Netherland And New York In The Seventeenth Century, Michael Eugene Gherke

Graduate Theses, Dissertations, and Problem Reports (ETD)

The European settlers who emigrated to America in the seventeenth century were decidedly patriarchal. Nevertheless, significant cultural differences in expressions of patriarchy among them existed. Specifically, the Dutch of New Netherland defined the gendered roles of women differently than did other European cultures. More than deputy-husbands, but less than full partner, seventeenth-century Dutch women in New Netherland were integral to the survival and promotion of their families' interests and preservation of the colony. English expropriation of New Netherland in 1664 and permanent acquisition in 1674 inaugurate a process of patriarchal acculturation that over time submerged the roles of Dutch women. …

Psychometric Properties Of The Social Interactions Questionnaire (Siq) In An Older Adult Sample, Kimberly Debra Kalish

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examined the psychometric properties of the Social Interactions Questionnaire (SIQ; Kalish & Edelstein, 1996), a quick and efficient tool to measure negative social interactions. Overwhelming evidence has emerged over the past decade indicating that negative social interactions (NSIs) are strongly related to measures of mental and physical health. A critique of existing measures of NSIs reveals long and cumbersome interviews that are comprised of some, but not all, of the critical elements of NSIs. The SIQ efficiently measures these critical elements, which include (a) perceived versus structural components of NSIs, (b) seven different types of NSIs, (c) overall …

Development Of A Micro-Dilution Tunnel System For In-Use, On-Board Heavy-Duty Vehicle Particulate Matter Emissions Measurement, Emily Deanna Cirillo Aug 2001

Development Of A Micro-Dilution Tunnel System For In-Use, On-Board Heavy-Duty Vehicle Particulate Matter Emissions Measurement, Emily Deanna Cirillo

Graduate Theses, Dissertations, and Problem Reports (ETD)

A novel portable particulate matter measuring system was designed, developed and qualified. The heavy-duty engine Federal Test Procedure (FTP) requires the use of a full-flow tunnel to measure particulate emissions from diesel fueled engines. However, a full-flow tunnel based constant volume sampler (CVS) system is not only expensive to build and maintain, it also requires a large work space. The portable micro-dilution system that could be used for measuring on-board, in-use emissions from heavy-duty vehicles would cost significantly less. The micro-dilution tunnel operates on the same principle as a full-flow dilution tunnel. The added advantage of the proposed design is …

Genetic Evaluation Of Cytochrome P450 Expression In Smoking And Nonsmoking Women, Satya Vijayanand Vadlamuri May 2001

Genetic Evaluation Of Cytochrome P450 Expression In Smoking And Nonsmoking Women, Satya Vijayanand Vadlamuri

Graduate Theses, Dissertations, and Problem Reports (ETD)

1. Regiospecific expression of CYP1A1 and CYP1B1 in human uterus of nonsmokers. The goal of this study was to investigate the expression of these isoforms in different regions of the human uterus. Expression was determined in the endometrium, endocervix and squamous (exocervix) regions from six nonsmoking women by using RT-PCR. The transcripts encoding for CYP1A1 were significantly higher (p < 0.05) in the squamous (exocervix) region compared to other areas. However the expression of CYP1B1 was significantly higher (p < 0.05) in the endometrium. CYP1B1 expression appeared to be extremely low in a woman in the secretory stage of the menstrual phase, relative to the endometrium of the other patients who were all in the proliferative stage at hysterectomy. It appears that variability in the expression of these isoforms may be responsible for the differential susceptibility to cancer in women.;2. Influence of menstrual phase and smoking status on expression of CYP1A1 and CYP1B1 in different regions of the uterus. The goal of this study was to investigate the expression of these isoforms in different regions of the uterus from smokers and nonsmokers. These results indicate that CYP1A1 and CYP1B1 are expressed variably in different regions of the human uterus. The expression of CYP1B1 may be susceptible both to hormonal control and cigarette smoking. The variability in the expression of these isoforms may be responsible for the differential susceptibility to cancer in some women.;3. The effect of menstrual phase on CYP3A expression in human endometrium. The CYP3A family consists of four closely related proteins. Of these, CYP3A3/4 is the most abundant P450 isoform and is responsible for metabolizing estrogen as well as a variety of therapeutic agents, whereas CYP3A7, the fetal liver form, is involved in the biosynthesis of estriol. The goal of this study was to evaluate the expression of these two major CYP3A isoforms in human uterine tissue during the proliferative (PROL) and secretory (SEC) phases of the menstrual cycle. Expression of CYP3A7 in endometrium appeared to be several fold higher (∼10-fold) in the proliferative phase compared to the secretory phase. CYP3A4 expression was comparable between the two phases of the menstrual cycle. The RTPCR results indicated differential expression of CYP3A7 in various phases of the menstrual cycle. These results indicate that CYP3A isoforms may be subject to hormonal regulation during the menstrual cycle in endometrium of premenopausal women. (Abstract shortened by UMI.).

English In The University Of Excellence, Joe Morris May 2001

English In The University Of Excellence, Joe Morris

Graduate Theses, Dissertations, and Problem Reports (ETD)

"The modern University," according to Bill Readings, "has had three ideas: the Kantian concept of reason, the Humboldtian idea of culture, and now the technobureaucratic notion of excellence." "Excellence" euphemistically describes the principle of the university as corporation, as geared toward revenue rather than ideology. This portrayal raises difficult questions for the humanities, as ideological domains. Taking Readings's The University in Ruins as a starting point, this study examines the English discipline within the "university of excellence," considering West Virginia University's department as a case study. It begins by charting the evolution of WVU's self-understanding, from an institution of culture …

Problem -Solving Communication Training And Behavioral Exchange For The Treatment Of Parent -Adolescent Conflict, Ethan Sage Long

Graduate Theses, Dissertations, and Problem Reports (ETD)

Elevated levels of parent-adolescent conflict have been associated with a number of adolescent problem behaviors. One treatment that appears to be effective in reducing family conflict is Problem Solving Communication Training (PSCT). Research has indicated that PSCT appears to be an effective and acceptable treatment program for reducing parent-adolescent conflict. However, researchers have suggested some possible limitations associated with PSCT treatment. Many of the identified limitations of PSCT potentially may be addressed with the inclusion of a Behavioral Exchange (BE) treatment component. Evidence supporting this hypothesis is provided by the documented success of Behavioral Marital Therapy, a treatment package that …
