Acculturation, Parental Control, and Adjustment among Asian Indian Women

Acculturation, Parental Control, and Adjustment among Asian Indian Women

Date: May 2007
Creator: Varghese, Anitha
Description: The present study examines the relationship between acculturation, parental control, and psychological adjustment among adult first and second-generation Asian Indian women who have immigrated, or whose parents have immigrated to the United States, from the Indian state of Kerala. Data from 73 participants indicate second-generation immigrants report poorer psychological adjustment than do their counterparts. Additionally, regression analyses reveal discomfort towards Kerala culture significantly predicts depressive symptoms, while high maternal control predicts self-esteem. Qualitative data were collected to provide richer understanding of immigrants' adaptation to the U.S. Implications of this research may impact mental health practitioners' ability to improve quality of life with Asian Indian women from Kerala.

Acculturative Processes and Their Impact on Self-Reports of Psychological Distress in Mexican-American Adolescents

Acculturative Processes and Their Impact on Self-Reports of Psychological Distress in Mexican-American Adolescents

Date: May 2003
Creator: Garrison, Lance A.
Description: The current study examined the effects of acculturative processes on the self-report of behavioral problems in Hispanic children ages 11-14. Acculturation was measured by the Acculturation Rating Scale for Mexican Americans-II (ARSMA-II) (ã Sage Publications, Thousand Oaks, CA, www.sagepub.com) (Cuellar, Arnold, and Maldonado, 1995) and the self-report of behavioral symptoms was assessed using the Youth Self-Report (ã T.M. Achenbach, Burlington, VT, www.aseba.com) (Achenbach, 1991). It was hypothesized that while both the linear and orthogonal categories of acculturation would account for a significant proportion of the variance in behavior problems in this age group, the orthogonal model would account for a larger proportion of variance due to its multidimensional nature. As well, it was hypothesized that the experimental Marginalization scales of the ARSMA-II would be predictive of behavioral problems. Multivariate analysis of variance was used to test these hypotheses and results were non-significant for the linear, orthogonal, and marginalization categories. The effects of the ethnic/cultural homogeneity of the region from which the sample was drawn, the buffering of social support, and the developmental aspects of ethnic identity are discussed as factors which may have influenced the potential impact of acculturative stress on psychological and behavioral functioning.

Accuracy and Efficiency in Computational Chemistry: The Correlation Consistent Composite Approach

Accuracy and Efficiency in Computational Chemistry: The Correlation Consistent Composite Approach

Date: August 2011
Creator: Wilson, Brent R.
Description: One of the central concerns of computational chemistry is that of efficiency (i.e. the development of methodologies which will yield increased accuracy of prediction without requiring additional computational resources – RAM, disk space, computing time). Though the equations of quantum mechanics are known, the solutions to these equations often require a great deal of computing power. This dissertation primarily concerns the theme of improved computational efficiency (i.e. the achievement of greater accuracy with reduced computational cost). Improvements in the efficiency of computational chemistry are explored first in terms of the correlation consistent composite approach (ccCA). The ccCA methodology was modified and this enhanced ccCA methodology was tested against the diverse G3/05 set of 454 energetic properties. As computational efficiency improves, molecules of increasing size may be studied and this dissertation explored the issues (differential correlation and size extensivity effects) associated with obtaining chemically accurate (within 1 kcal mol-1) enthalpies of formation for hydrocarbon molecules of escalating size. Two applied projects are also described; these projects concerned the theoretical prediction of a novel rare gas compound, FKrOH, and the mechanism of human glutathione synthetase’s (hGS) negative cooperativity. The final work examined the prospect for the parameterization of the modified embedded atom ...

Accuracy and Interpretability Testing of Text Mining Methods

Accuracy and Interpretability Testing of Text Mining Methods

Date: August 2013
Creator: Ashton, Triss A.
Description: Extracting meaningful information from large collections of text data is problematic because of the sheer size of the database. However, automated analytic methods capable of processing such data have emerged. These methods, collectively called text mining first began to appear in 1988. A number of additional text mining methods quickly developed in independent research silos with each based on unique mathematical algorithms. How good each of these methods are at analyzing text is unclear. Method development typically evolves from some research silo centric requirement with the success of the method measured by a custom requirement-based metric. Results of the new method are then compared to another method that was similarly developed. The proposed research introduces an experimentally designed testing method to text mining that eliminates research silo bias and simultaneously evaluates methods from all of the major context-region text mining method families. The proposed research method follows a random block factorial design with two treatments consisting of three and five levels (RBF-35) with repeated measures. Contribution of the research is threefold. First, the users perceived a difference in the effectiveness of the various methods. Second, while still not clear, there are characteristics with in the text collection that affect the ...

Accuracy of Self-Reported Height, Weight, and Calculated BMI and Resulting FITNESSGRAM® Healthy Fitness Zone Classification

Accuracy of Self-Reported Height, Weight, and Calculated BMI and Resulting FITNESSGRAM® Healthy Fitness Zone Classification

Access: Use of this item is restricted to the UNT Community.
Date: May 2006
Creator: Rowell, Chelsie Joyce
Description: The determination of adiposity in adolescents is often assessed with calculations of body mass indices (BMI). Researchers often obtain these measurements from self-reported (SR) values. The purpose of this study was to determine the accuracy of SR height, weight, and calculated BMI (from height and weight). SR and actual measured (ME) BMI values were compared with standards from the FITNESSGRAM® Healthy Fitness Zone (HFZ) classifications. SR height and calculated BMI were found to be accurate while SR weight was, on average, underreported by 4.77 lbs. Because of these errors in SR height and weight, accuracy of classification into the FITNESSGRAM® HFZ was compromised. Consequently, it is important that researchers ascertain actual values of height and weight when measuring adolescents rather than use those from self-reports.

Accuracy variations in human facial identification based on time of exposure.

Accuracy variations in human facial identification based on time of exposure.

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Cowle, Kenneth M.
Description: This study examined the relationship between time of exposure to the human face and accurate subsequent photo line-up identification. A volunteer group of 124 undergraduate students was divided into three approximately equal sized subgroups. The three groups were then exposed to a video or a portion of a video depicting a theft. Exposure times ranged from two minutes to 30 seconds. The subjects were then given a questionnaire and shown a photo line-up of the mock perpetrator and five foils. Subjects were asked to identify the perpetrator and mark that identification on the questionnaire. Results of the experiment indicated that the longer a subject was exposed the greater the possibility of an accurate identification.

Acting Ethically: Behavior and the Sustainable Society

Acting Ethically: Behavior and the Sustainable Society

Date: August 2007
Creator: Sewell, Patrick
Description: One of the most important factors for creating the sustainable society is that the individuals in that society behave in an environmentally sustainable fashion. Yet achieving appropriate behavior in any society is difficult, and the challenge is no less with regards to sustainability. Three of the most important factors for determining behavior have recently been highlighted by psychologists: personal efficacy, social influence, and internal standards. Because these three factors play a prominent role in behavior, it is necessary to examine what role they play in creating sustainability and how they may be utilized to achieve optimal behavior patterns. Ultimately, in order to achieve sustainability solutions must focus on individual action, realistic governmental regulation, and sustained, direct encounters with the natural world. While much time and energy has been spent on social influence and personal efficacy, less has been devoted to internal standards and this area needs more attention if there is to be any realistic attempt at creating proper behavior patterns.

Actinoplanes Philippinensis: Effect of Carbon Sources on Zoospore Production

Actinoplanes Philippinensis: Effect of Carbon Sources on Zoospore Production

Date: May 1968
Creator: White, Olivia
Description: Actinomycetes are able to utilize a great variety of carbohydrates, like sugar. The particular kind of sugar and its concentration has decisive effect on the growth of microorganisms. The proper nutritional media aids also in the production of spores. Based on this generalization, that the growth and sporulation of microorganisms are greatly influenced by the nature and the concentration of carbohydrates, an attempt has been made to study Actinoplanes philippinensis with respect to this influence.
