Peptide-based hidden Markov model for peptide fingerprint mapping.

Peptide-based hidden Markov model for peptide fingerprint mapping.

Access: Use of this item is restricted to the UNT Community.
Date: December 2004
Creator: Yang, Dongmei
Description: Peptide mass fingerprinting (PMF) was the first automated method for protein identification in proteomics, and it remains in common usage today because of its simplicity and the low equipment costs for generating fingerprints. However, one of the problems with PMF is its limited specificity and sensitivity in protein identification. Here I present a method that shows potential to significantly enhance the accuracy of peptide mass fingerprinting, using a machine learning approach based on a hidden Markov model (HMM). This method is applied to improve differentiation of real protein matches from those that occur by chance. The system was trained using 300 examples of combined real and false-positive protein identification results, and 10-fold cross-validation applied to assess model discrimination. The model can achieve 93% accuracy in distinguishing correct and real protein identification results versus false-positive matches. The receiver operating characteristic (ROC) curve area for the best model was 0.833.

Perceived attractiveness and personality attributes: A gender and racial analysis

Perceived attractiveness and personality attributes: A gender and racial analysis

Date: May 2000
Creator: Olby, Brian C.
Description: Subjects rated 12 female body shapes with respect to their physical attractiveness, and the extent to which they would be expected to possess various personality characteristics. The shapes were varied using 3 levels of overall weight and 4 levels of body shapeliness. The sample was modified to control for socioeconomic factors and results are based on 297 undergraduates from Caucasian, African American, and Hispanic racial backgrounds. Loglinear analyses revealed that men and women, regardless of racial background, rated shapely underweight females as most physically attractive, sexy, and ideal for a woman, followed by normal weight figures of similar proportion. African Americans, women in particular, judged the shapely normal weight figures more favorably than the other subjects. Multidimensional scaling and subsequent frequency analyses showed that those figures judged as most attractive, sexy, and ideal were also expected to be fairly emotionally stable, and most successful and interpersonally competitive, but least faithful, kind, and family-oriented. Overweight female shapes, while rated as least physically attractive, sexy, and emotionally stable, were expected to be most family-oriented, kind, and faithful. Shapely normal weight figures were judged to be attractive and sexy, and were assumed to possess a moderate amount of the personality traits in question. ...

Perceived attributes of diffusion of innovation theory as predictors of Internet adoption among faculty members of Imam Mohammed Bin Saud University.

Perceived attributes of diffusion of innovation theory as predictors of Internet adoption among faculty members of Imam Mohammed Bin Saud University.

Date: May 2007
Creator: Almobarraz, Abdullah
Description: The Internet is the most common communication and research tool worldwide. Perusal of the World Wide Web quickly reveals the variety of information available. Internet adoption can be considered the late 20th century's most important event. In academic environments today, Internet use among faculty members has been widely expanded, with professors now integrating Internet technology into classroom activities. Imam Muhammad Bin Saud Islamic University (IMSU) is a pioneering public university in Saudi Arabia. Until recently, some faculty members at IMSU were unable to access the Internet through the university. It is important to study the effects of this delay on faculty members regarding research and academic activities. This study identified the statistically significant differences in demographic characteristics of Internet adopters and non-adopters among faculty members at IMSU, examined whether faculty members' perceptions of the Internet affected adoption, determined if the university administration's decisions impacted faulty members' decisions to adopt the Internet, identified factors motivating faculty members to adopt the Internet, identified obstacles influencing faculty members' decisions to use the Internet, and determined whether innovation characteristics as perceived by faculty members predicted Internet adoption. Using Rogers' diffusion of innovation theory, the influence of eight attributes were examined regarding Internet adoption among ...

Perceived barriers to faculty participation in distance education at a 4-year university.

Perceived barriers to faculty participation in distance education at a 4-year university.

Access: Use of this item is restricted to the UNT Community.
Date: August 2003
Creator: Hebert, Janet Gwen
Description: The purpose of this study was to identify perceived barriers to faculty participation in distance education courses in a 4-year university. The literature review was divided into four general areas, each of which may act as a barrier to faculty participation; training, administrators, rewards/compensation, and faculty characteristics/demographics. The research population consisted of 570 faculty and 59 administrators from the eight UNT schools/colleges. Dr. Kristin Betts developed the survey instrument in 1998 for similar research conducted at the George Washington University. Analysis of the collected data revealed that there was no statistically significant relationship found between faculty characteristics and faculty participation in distance education. Faculty participants and administrators disagreed on which factors, from a list of 34 items, had motivated faculty to participate in distance education. Nonparticipants and administrators disagreed on which of the factors, if not available, would be barriers to faculty participation in distance education. Participants and nonparticipants disagreed regarding the level to which selected rewards and compensations had motivated faculty to participate, and the lack of which would inhibit faculty participation in distance education. Finally, 71% of the participants had participated or planned to participate in distance education training compared to only 33% of the nonparticipants. It is ...

Perceived Change in Behavior Associated with Peer Feedback in Work Teams

Perceived Change in Behavior Associated with Peer Feedback in Work Teams

Access: Use of this item is restricted to the UNT Community.
Date: August 2005
Creator: DeJarnett, Nicole
Description: This study investigated if the use of a team feedback system resulted in peers perceiving a change in behavior. Personality variables such as conscientiousness, agreeableness, and extraversion were examined as possible moderators. Self-ratings and peer ratings were collected from 164 individuals through the use of the Center for Collaborative Organizations' Team Feedback System. Using polynomial regression, it was determined that time 1 peer ratings predicted behavior change and the combination of conscientiousness variables moderated peer perceived behavior change.

Perceived Effects of a Mid-length Study Abroad Program

Perceived Effects of a Mid-length Study Abroad Program

Date: May 2012
Creator: Corbin, Jill K.
Description: The focus of the study was the University of Dallas’ Rome Program, a mid-length study abroad program on the university’s campus in Rome, Italy. The program is designed to provide participants with the opportunity to encounter firsthand Western tradition by integrating the core curriculum through classroom teachings and class excursions, thus solidifying the foundation of the participants’ undergraduate education. Beyond this purpose, the Rome Program does not operate from established goals and objectives for student experience. I consulted relevant research literature to construct a schema of domains of development appropriate to this qualitative study. These domains were intellectual development, global perspective, career development, and spiritual development. I interviewed 20 University of Dallas seniors who participated in the mid-length study abroad program between fall 2009 and spring 2011, using an extended, semi-structured interview protocol. The participants included 11 females and 9 males; 19 White and 1 Hispanic. The findings were supported by subsequent review by 4 of the interviewed students. I found generally strong but inconsistent support for student development in each of the domains. A number of sub-themes are reported. Through the interviews, an additional theme of personal development emerged and is reported. Although the findings generally support the conclusion ...

Perceived features and similarity of images: An investigation into their relationships and a test of Tversky's contrast model.

Perceived features and similarity of images: An investigation into their relationships and a test of Tversky's contrast model.

Date: May 2005
Creator: Rorissa, Abebe
Description: The creation, storage, manipulation, and transmission of images have become less costly and more efficient. Consequently, the numbers of images and their users are growing rapidly. This poses challenges to those who organize and provide access to them. One of these challenges is similarity matching. Most current content-based image retrieval (CBIR) systems which can extract only low-level visual features such as color, shape, and texture, use similarity measures based on geometric models of similarity. However, most human similarity judgment data violate the metric axioms of these models. Tversky's (1977) contrast model, which defines similarity as a feature contrast task and equates the degree of similarity of two stimuli to a linear combination of their common and distinctive features, explains human similarity judgments much better than the geometric models. This study tested the contrast model as a conceptual framework to investigate the nature of the relationships between features and similarity of images as perceived by human judges. Data were collected from 150 participants who performed two tasks: an image description and a similarity judgment task. Qualitative methods (content analysis) and quantitative (correlational) methods were used to seek answers to four research questions related to the relationships between common and distinctive features ...

Perceived Racial Discrimination and Psychiatric Outcomes among Asian Americans

Perceived Racial Discrimination and Psychiatric Outcomes among Asian Americans

Date: December 2009
Creator: Varghese, Anita
Description: The present study related generational status, family dynamics, and perceptions of racial discrimination (PRD) to acute psychiatric outcomes among a nationally representative Asian American sample (N = 2095), using data from the National Latino and Asian American Study (NLAAS). High self-reports of PRD were correlated with endorsement of clinical depression and suicidality as predicted. Regression analyses suggested that high PRD, low family cohesion, and high family conflict served as significant predictors of poor mental health independently, but moderator hypotheses predicting the interaction of these factors were not supported. Clinical and research implications are provided.

Perceived Submaximal Leg Extension Forces of Young Adult Males

Perceived Submaximal Leg Extension Forces of Young Adult Males

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Ludke, Andrew William
Description: The purpose was to examine actual force (AF) productions of males for accuracy during leg extensions when given a random desired force (DF) ranging from 10-90% of maximal force (MF). Thirty males ranging from 18 to 30 years of age (M = 21.99 + 3.04), who had no previous experience with the test equipment, went through 9 randomly ordered submaximal efforts followed by a maximal effort. Correlations between AF and DF were high (r > .79) and test-retest was consistent between AF (r = .87) and MF (r = .90). Participants consistently undershot DF on both test and retest from 20-90% and overshot DF only at 10%. Power functions revealed exponents of less than 1, indicating that AF grows slower then DF for both test .70 (.95 CI = .63 - .77) and retest .66 (.95 CI = .60 - .73). The results replicate a prior study by Jackson, Martin, Koziris, Ludtke, and Dishman (2001) that used incremental rather than random increases in DF.
