Culture and Anxiety: a Cross-Cultural Study

Culture and Anxiety: a Cross-Cultural Study

Date: December 1998
Creator: Abbassi, Amir
Description: By measuring interactions among and between anxiety and the independent variables of country of origin, gender, level of education, and age, this study attempted to gain insight into how students from different countries experience anxiety on a U.S. college campus. Results of the Multivariate Analysis of Variance (MANOVA) and the univariate test(ANOVA) indicated that the gender and level of education of the subjects made no significant difference. However, when it came to country of origin, there were significant differences between two of the cultural groups and respective anxiety level. Findings also support a positive correlation between age and anxiety levels, with the youngest participants having the lowest anxiety levels.

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces

Date: May 1999
Creator: Abbott, John C.
Description: The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata ...

An Analysis of Corporate Accounting and Reporting Practices in Bahrain

An Analysis of Corporate Accounting and Reporting Practices in Bahrain

Date: December 1993
Creator: Abdul-Rahim, Hassan M.
Description: The primary objective of this dissertation is to determine the factors that have shaped the corporate financial reporting practices in Bahrain. Prior researchers have offered two explanations, environmental factors and cultural importation, for the emergence of financial reporting practices in developing countries. The environmental explanation suggests that a nation's financial reporting practices will be shaped by its socioeconomic structure. The cultural importation explanation states that the desire for international legitimacy creates incentives for developing nation to adopt Western financial reporting practices. Bahrain provided an excellent environment in which to examine the two explanations since its public and closed corporations have similar economic characteristics. Only public corporations are legally required to publish financial reports. I posited that public corporations would try to gain legitimacy for their published reports by adopting Western standards, while closed corporations would not have a similar incentive. I used an interpretive framework to analyze the Bahrain socioeconomic environment and to examine the general financial reporting practices of Bahraini corporations. I found that closed corporations provided data responsive to the Bahraini environment. Public corporations, however, adopted International Accounting Standards. My analysis supported prior researchers7 findings that colonialism, the need for international legitimacy, and international audit firms were important ...

Forest Landscape Dynamics: a Semi-Markov Modeling Approach

Forest Landscape Dynamics: a Semi-Markov Modeling Approach

Date: August 1997
Creator: Ablan, Magdiel
Description: A transition model (MOSAIC) is used to describe forest dynamics at the landscape scale. The model uses a semi-Markov framework by considering transition probabilities and Erlang distributed holding times in each transition. Parameters for the transition model are derived from a gap model (ZELIG). This procedure ensures conceptual consistency of the landscape model with the fine scale ecological detail represented by the forest gap model. Spatial heterogeneity in the transition model is driven by maps of terrain with characteristics contained in a Geographic Information System (GIS) database. The results of the transition model simulations, percent cover forest type maps, are exported to grid-maps in the GIS. These cover type maps can be classified and used to describe forest dynamics using landscape statistics metrics. The linkage model-GIS enhances the transition model spatial analytical capabilities. A parameterization algorithm was developed that takes as input gap model tracer files which contain the percent occupation of each cover type through time. As output, the algorithm produces a file that contains the parameter values needed for MOSAIC for each one of the possible transitions. Parameters for the holding time distribution were found by calculating an empirical estimate of the cumulative probability function and using a ...

Application of Synthetic Peptides as Substrates for Reversible Phosphorylation

Application of Synthetic Peptides as Substrates for Reversible Phosphorylation

Date: August 1992
Creator: Abukhalaf, Imad Kazem
Description: Two highly homologous synthetic peptides MLC(3-13) (K-R-A-K-A-K-T-TK-K-R-G) and MLC(5-13) (A-K-A-K-T-T-K-K-R-G) corresponding to the amino terminal amino acid sequence of smooth muscle myosin light chain were utilized as substrates for protein kinase C purified from murine lymphosarcoma tumors to determine the role of the primary amino acid sequence of protein kinase C substrates in defining the lipid (phosphatidyl serine and diacylglycerol) requirements for the activation of the enzyme. Removal of the basic residues lysine and arginine from the amino terminus of MLC(3-13) did not have a significant effect on the Ka value of diacylglycerol. The binding of effector to calcium-protein kinase C appears to be random since binding of one effector did not block the binding of the other.

Female Inheritors of Hawthorne's New England Literary Tradition

Female Inheritors of Hawthorne's New England Literary Tradition

Date: August 1994
Creator: Adams, Dana W. (Dana Wills)
Description: Nineteenth-century women were a mainstay in the New England literary tradition, both as readers and authors. Indeed, women were a large part of a growing reading public, a public that distanced itself from Puritanism and developed an appetite for novels and magazine short stories. It was a culture that survived in spite of patriarchal domination of the female in social and literary status. This dissertation is a study of selected works from Nathaniel Hawthorne, Sarah Orne Jewett, and Mary E. Wilkins Freeman that show their fiction as a protest against a patriarchal society. The premise of this study is based on analyzing these works from a protest (not necessarily a feminist) view, which leads to these conclusions: rejection of the male suitor and of marriage was a protest against patriarchal institutions that purposely restricted females from realizing their potential. Furthermore, it is often the case that industrialism and abuses of male authority in selected works by Jewett and Freeman are symbols of male-driven forces that oppose the autonomy of the female. Thus my argument is that protest fiction of the nineteenth century quietly promulgates an agenda of independence for the female. It is an agenda that encourages the woman to ...

Bias in the Diagnosis and Treatment of Gay Males

Bias in the Diagnosis and Treatment of Gay Males

Date: December 1996
Creator: Adams, Pamela (Pamela Ann)
Description: The purpose of this study was to explore heterosexual bias in the diagnosis and treatment of gay males. Two hundred-fifty (134 males and 116 females) mental health professionals from the Division of Psychotherapy (29) of the American Psychological Association participated in the study. Participants were randomly assigned to one of two case history conditions, which presented a 35-year-old male seeking therapy. Both conditions were equivalent with regards to the presenting problem (i.e., diagnostic symptoms) with the exception of his significant other (i.e., gay vs. non-gay condition). Potential bias was measured through a diagnostic rating Likert scale and a treatment plan questionnaire. Other independent variables that could potentially have an effect on diagnostic ratings were explored, such as gender, year of graduation, and theoretical orientation of the respondents. Results of the statistical analyses failed to confirm evidence of heterosexual bias. Implications for further research and training are discussed.

Chronic Ventricular Sympathectomy : Effects on Myocardial Metabolism

Chronic Ventricular Sympathectomy : Effects on Myocardial Metabolism

Date: August 1993
Creator: Adix Longlet, Nancy J.
Description: Chronic ventricular sympathectomy elicits changes in the coronary circulation, myocardial oxygen consumption and size of infarction resulting fromcoronary occlusion. These changes indicate a change occurring in the basic metabolism of the heart in response to the removal of its sympathetic nervous input. This hypothesis was tested using two groups of dogs, a shamoperated control and a ventricular sympathectomized group. The sympathectomy procedure was an intrapericardial surgical technique which selectively removes ventricular sympathetic input. Four weeks after surgery, left ventricular tissue samples were obtained and rapidly frozen to -80°C. Selected metabolic variables were then compared between the two groups.

Effect of Task Appropriateness, Social Comparison, and Feedback on Female Goals, Performance, and Self-Confidence with a Motor Task

Effect of Task Appropriateness, Social Comparison, and Feedback on Female Goals, Performance, and Self-Confidence with a Motor Task

Date: May 1990
Creator: Adler, William P.
Description: Lenney (1977) concluded that achievement gender differences were predicted by females' lower self confidence and expectancies in competitive situations, identifying three variables that mediated female self confidence in achievement situations, (1) task appropriateness. (2) social comparison, and (3) feedback. The present study manipulated all three mediating variables with 240 undergraduate 18-25 year old female subjects with the pursuit rotor task that requires tracking a moving (40 rpm's) white light with a hand-held stylus for 60 seconds. Response measurement was based upon time on target. Subjects were tested over five trials while setting goals for each trial. Females were randomly assigned to a male appropriate, female appropriate, or gender neutral task condition, a competition or alone condition, and to one of four feedback conditions (no feedback, feedback about own performance only, feedback about own performance that provided the perception that subject was performing better than an opponent and/or average on each trial, or feedback about own performance that provided the perception that subject was performing poorer than an opponent and/or average on each of the five trials). Results from the 2 (social comparison) X 3 (task appropriateness) X 4 (feedback) ANOVA were contradictory to previous findings (Corbin, 1981; Petruzzello & Corbin, ...

Parental Cultural Mistrust, Background Variables, and Attitudes Toward Seeking Mental Health Services for Their Children

Parental Cultural Mistrust, Background Variables, and Attitudes Toward Seeking Mental Health Services for Their Children

Date: August 1990
Creator: Ahluwalia, Ekta
Description: Attitudes toward mental illness and the willingness to seek psychological treatment for their children among ethnic minority group parents were investigated. Participants consisted of black, Hispanic, Native American and Asian parents. All parents were given the Terrell and Terrell Cultural Mistrust Inventory, Cohen and Struening Opinions About Mental Illness Scale, Reid-Gundlach Social Services Satisfaction Scale, Fischer-Turner Attitudes Toward Seeking Professional Help Scale, and Ahluwalia Parents' Psychological Help-Seeking Inventory. A multiple regression model was used to explore the purpose of this study. Parental mistrust level, ethnicity, education, income level, and opinions about mental illness served as predictor variables. The criterion variables consisted of scores on the Social Services Satisfaction Scale and Attitudes Toward Seeking Professional Psychological Help Scale. The results indicated that the most significant predictor of psychological help-seeking was parental cultural mistrust level. Parents with higher cultural mistrust levels were less likely to seek help. Education was also predictive of black and Native American parents' help-seeking attitude and willingness to seek psychological help for their children. Black and Native Americans with lower levels of education were less willing to seek treatment for their children than members of those ethnic groups with higher levels of education. Ethnicity was also related to ...

"Beowulf": Myth as a Structural and Thematic Key

"Beowulf": Myth as a Structural and Thematic Key

Date: May 1990
Creator: Aitches, Marian A. (Marian Annette)
Description: Very little of the huge corpus of Beowulf criticism has been directed at discovering the function and meaning of myth in the poem. Scholars have noted many mythological elements, but there has never been a satisfactory explanation of the poet's use of this material. A close analysis of Beowulf reveals that myth does, in fact, inform its structure, plot, characters and even imagery. More significant than the poet's use of myth, however, is the way he interlaces the historical and Christian elements with the mythological story to reflect his understanding of the cyclic nature of human existence. The examination in Chapter II of the religious component in eighth-century Anglo-Saxon culture demonstrates that the traditional Germanic religion or mythology was still very much alive. Thus the Beowulf poet was certainly aware of pre-Christian beliefs. Furthermore, he seems to have perceived basic similarities between the old and new religions, and this understanding is reflected in the poem. Chapter III discusses the way in which the characterization of the monsters is enriched by their mythological connotations. Chapter IV demonstrates that the poet also imbued the hero Beowulf with mythological significance. The discussion in Chapter V of themes and type-scenes reveals the origins of ...

Perceptions of Student Affairs Services by Students and Student Affairs Personnel at Andrews University, Berrien Springs, Michigan

Date: December 1995
Creator: Akos, Hosea Dodo
Description: The purpose of this study was to investigate the perceptions of students and student affairs personnel of student affairs services at Andrews University's main campus in Berrien Springs, Michigan. A modified questionnaire, based on the work of Selgas and Blocker (1974) and Glenister (1977), was developed for this study. Eleven student services found in the Council for the Advancement of Standards for Student Services/Development Program's guidelines were included. A random sample of 280 students at Andrews University received surveys, with 165 (59%) responding. The 30 full-time student affairs personnel also received surveys, with 20 (67%) responding. Students and student affairs personnel rated their perceptions of student services, using 77 statements associated with these services. Services were rated on a 6-point scale in the categories of status of knowledge, relative importance, and effectiveness. Respondents were asked to include additional comments concerning the services and to provide biographical data. The following are some of the main findings: Significant differences between students' and student affairs personnel's status of knowledge of student services were found in career planning/employment, commuter programs/services, counseling services/substance abuse education, religious programs/services, student activities, and wellness/health. Significant differences between the two groups' perceptions of relative importance of student services were ...

Structural and Photoelectron Emission Properties of Chemical Vapor Deposition Grown Diamond Films

Structural and Photoelectron Emission Properties of Chemical Vapor Deposition Grown Diamond Films

Date: August 1998
Creator: Akwani, Ikerionwu Asiegbu
Description: The effects of methane (CH4), diborone (B2H6) and nitrogen (N2) concentrations on the structure and photoelectron emission properties of chemical vapor deposition (CVD) polycrystalline diamond films were studied. The diamond films were grown on single-crystal Si substrates using the hot-tungsten filament CVD technique. Raman spectroscopy and x-ray photoelectron spectroscopy (XPS) were used to characterize the different forms of carbon in the films, and the fraction of sp3 carbon to sp3 plus sp2 carbon at the surface of the films, respectively. Scanning electron microscopy (SEM) was used to characterize the surface morphology of the films. The photoelectron emission properties were determined by measuring the energy distributions of photoemitted electrons using ultraviolet photoelectron spectroscopy (UPS), and by measuring the photoelectric current as a function of incident photon energy.

Current and Future Trends in Computer Use in Elementary School Settings

Date: August 1999
Creator: Al-Awidi, Hamed M.
Description: The study examined current and future trends in computer use in elementary school settings. A survey instrument was developed and validated for distribution to a random sample of 200 technology coordinators in the public school districts in the state of Texas from whom 95 responses were received. The survey instrument was used to obtain information about five areas of computer use in elementary schools. These areas are: physical configurations, instructional uses, implementation issues, training and staff development, and Internet use. The study found that all public school districts that participated in the study have acquired computer hardware in their elementary schools. In addition, some other advanced computer technology components are starting to be found in elementary schools, such as teacher workstations, CD-ROM, interactive video, computer multimedia, LCD panels, and laser printers. Respondents reported that elementary school teachers in their districts have incorporated computers into their classrooms as an instructional tool and many changes have occurred in teachers’ teaching styles due to computers. However, there are some problems that hinder the effective use of computers. The major problem is lack of training. A high percentage of respondents, 81.3%, indicated that the majority of their elementary school teachers had completed less than ...

Perceptions of Managers in Kuwait on the Role of the Multinational Corporations in Change in Kuwait

Date: May 1990
Creator: Al-Daeaj, Hamad S. (Hamad Saleh)
Description: The purpose of this study is to investigate the perceptions of managers in Kuwait (both Kuwaiti and non- Kuwaiti) on the effects of multinational corporations (MNCs) in Kuwait and whether these effects were beneficial. The problem motivating this study is the effects that MNCs have on the social, cultural, political, legal, economic, business, and technological environments of their host countries, especially in developing nations. This study is based on a survey of the perceptions of 1,344 managers in Kuwait on the role of MNCs in changes in Kuwait. A review of the literature on MNCs and their relationships with their host countries is provided. This review focuses on four major environmental dimensions (Social-Cultural, Political-Legal, Business-Economic, and Technological) that are affected by MNCs. The factor analysis performed for this study supports this classification of the dimensions in the environment. An English questionnaire was developed from the list of major items in each of these dimensions. An Arabic version was developed using a "double-translation method." Both the English and Arabic versions of the questionnaire were pilot tested. The instrument proved to be reliable and valid. The study utilizes a 2 x 3 block design, categorizing subjects by nationality (Kuwaiti, other Arab, others) ...

A Structural Equation Analysis of Intergenerational Differences in Attitudes toward Individual Modernity in the United Arab Emirates: Implications for Cross-Cultural Research

Date: May 1997
Creator: Al-Ghazy, Faris M.
Description: It has been widely believed that modernity is a byproduct of a nuclear family system, a highly urbanized society, and a secular way of life. As such, developing countries are characterized as modern insofar as their social and cultural structures are able to correspond to these criteria. To examine the validity of these propositions, data on two randomly-selected generations--daughters and mothers in the United Arab Emirates--were generated.
