Part I: Solid State Studies of Larger Calixarenes : Part II: Synthesis and Characterization of Metallocalixarenes

Part I: Solid State Studies of Larger Calixarenes : Part II: Synthesis and Characterization of Metallocalixarenes

Date: May 1998
Creator: Smith, Janna Marie
Description: Calixarenes are a class of macrocyclic compounds that have garnered interest in large part because of their ability to form host-guest complexes with various types of molecules. For all of the studies of complex formation by calixarenes, most of the work to date has concentrated upon the smaller calixarenes, and little is understood about the relationship between the complexes formed when in solution and that observed in the solid state. The first part of the study, presented in Chapter 3, is of the solid-state properties of two of the larger calixarenes, and in comparison to other reported structures reveals patterns to the observed conformations both in the solid state and in solution. The formation of metal complexes has also been investigated and has focused extensively upon the metals as guests. Thus, the ability of the calixarenes to act as ligands in inorganic complexes has been virtually untapped, despite the polyoxo binding site they can easily provide, and very few metallocalixarenes have been reported. The second part of this study goes beyond the simple solid-state properties of such compounds, and involves the synthesis of several metallocalixarenes as part of a project directed at the functionalization of calixarenes with the components of ...

Participant's perceptions of online staff development and learning tools.

Participant's perceptions of online staff development and learning tools.

Date: May 2003
Creator: Smolka, Jennifer
Description: This study analyzed participants in an online professional development and certification program can to see if they could predict the learning value of individual distance education tools. The Texas Center for Educational Technology (TCET) funded by the Texas Telecommunications Infrastructure Fund (TIF) designed the Technology Applications Certification Program (TACP). In the TACP, students are offered four graduate level classes which, when combined, meet the standards for the State Board for Educator Certification (SBEC) Technology Applications certification. The four courses that comprise the TACP are Computers in Education, Introduction to the Internet, Multimedia in Technology Applications, and Introduction to Video Technologies. The first course started in January 2002 with approximately 706 participants in 40 cohorts across the state of Texas. The TACP combines two different worlds of technology training. Half of the coursework was completed through asynchronous content and discussions, while the remaining classes were hands-on classes in local district computer labs. These face-to-face meetings enabled learners to get hands-on training with direct assistance. Between the online and face-to-face segments, a variety of learning tools were introduced to the participants. Participants were surveyed through the online Snapshot Survey in January and again in September.

Participation in a study-abroad program and persistence at a liberal arts university.

Participation in a study-abroad program and persistence at a liberal arts university.

Date: December 2003
Creator: Young, Denise York
Description: This study used a quasi-experimental design with 1,237 students to investigate the association between participation in a study-abroad program and persistence at a liberal arts university. The theoretical basis for the study was Tinto's Theory of Individual Departure. The independent variable of interest, also known as the treatment, was participation in the University of Dallas Rome Program during the sophomore year. The control group consisted of students who were qualified to participate in the Rome Program, but chose not to do so. The dependent variable was the number of fall and spring semesters enrolled as an undergraduate at the University of Dallas post-treatment through spring 2003. Nine variables that measured background characteristics, academic integration, and social integration explained 3.8% of the variation in number of semesters enrolled post-treatment. Participation in the Rome Program explained an additional 4.2%. In all of the statistical measures examined in this study (incremental increase in R2, b weights, adjusted β weights, and structure coefficients), there was evidence of an important positive association between participation in the Rome Program and persistence. Based on the b weight in the regression equation, holding all other variables constant, students who participated in the Rome Program persisted on average .83 ...

Participation in Student Financial Aid Programs during the Freshman Year and Persistence in a Private University

Participation in Student Financial Aid Programs during the Freshman Year and Persistence in a Private University

Date: August 1997
Creator: Munson, Leo W.
Description: The study determined the overall persistence rate of first-time full-time entrants into a mid-sized private university during the fall semesters 1989 to 1991 to the 2nd year (1990 to 1992). The study compared the retention rate of recipients and nonrecipients of a variety of financial aid programs. Included is a comparison of groups receiving various types of financial assistance and whether or not there are differences between the groups with respect to types of assistance, gender, ethnicity (African American, Hispanic, Anglo), high school grade point average, and national test scores (SAT, ACT). The types of assistance studied were categorized by academic scholarships, university-operated student employment, need-based grants, activity awards, entitlements, and loans. The question of whether renewal, elimination, or reduction in assistance relates to retention was also studied.

Participatory Design in Academic Libraries: New Reports and Findings

Participatory Design in Academic Libraries: New Reports and Findings

Date: February 2014
Creator: Council on Library and Information Resources
Description: This report looks at how staff at eight academic institutions gained new insight about how students and faculty use their libraries, and how the staff are using these findings to improve library technologies, space, and services. Participatory design is a relatively recent approach to understanding library user behavior. It is based on techniques used in anthropological and ethnographic observation. The report is based on a series of presentations at the second CLIR Seminar on Participatory Design of Academic Libraries, held at the University of Rochester’s River Campus June 5-7, 2013. Chapters focus on projects at the University of Colorado, Boulder; Colby College; University of Connecticut; Columbia University; Rush University Medical Center; Purdue University; Northwestern University; and the University of Rochester. David Lindahl, of the University of Missouri-Kansas City, provided the keynote.

Partisanship and Judicial Decision Making in U.S. Courts of Appeal

Partisanship and Judicial Decision Making in U.S. Courts of Appeal

Date: December 2002
Creator: Meaders, Eddie Loyd
Description: Partisanship is found in voter and Congressional behavior. Members of the federal judiciary should behave similarly. I utilize cases involving the Republican and Democratic parties from 1966 to 1997 and examine the voting behavior of federal Courts of Appeal judges. I utilize both cross tabulations and a Logit regression model to determine the likelihood appellate judges will vote for their own party and against the opposition.

Partner abuse: Health consequences to women.

Partner abuse: Health consequences to women.

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Warren, Ann Marie
Description: Intimate partner violence is endemic in the United States. According to the American Medical Association (1992), one-fifth to one-third of women will sustain violence from a partner or ex-partner in their lifetime. The relevant literature was organized by ICD-9-CM categories. This study examined the health consequences of partner abuse in a sample of community women using a sample consisting of 564 women in three ethnic groups. Because prior research has failed to account for variations by type of abuse on health consequences, this study assessed psychological abuse, violence and sexual aggression by women's partners. To determine whether or not different types of abuse had an effect on women's health, hierarchical regression analyses were conducted. The regression equations were calculated for women within each ethnic group to facilitate identification of similarities and differences and to control for ethnic differences in risk for specific diseases. The results were consistent with past research on health consequences of abuse and extended the prior literature by showing that psychological abuse had a pervasive effect on health conditions, distress and use of health care resources. Additionally, ethnic differences emerged. As expected, ethnicity appeared to function as a moderator. Clinical implications and recommendations are made for future ...
