Applying Cognitive Load Theory to the Design of Online Learning.

Description: The purpose of the study was to investigate the application of cognitive load theory to the design of online instruction. Students in three different courses (N = 146) were measured on both learning performance and perceptions of mental effort to see if there were any statistically significant differences. The study utilized a quasi-experimental posttest-only control group design contrasting modified and unmodified instructional lessons. Both groups were given a posttest to measure knowledge gained from the lesson (cognitive domain of learning) and perceptions of mental effort involved. Independent samples t-tests were used to compare the mean performance scores of the treatment groups (i.e. the sections using redesigned materials) versus the control groups for all three courses. Cohen's d was also computed to determine effect size. Mental effort scores were similarly compared for each group on the overall cognitive load score, for a total of six data points in the study. Of the four hypotheses examined, three (H1, H2, H4) found no statistically significant difference between the experimental and control groups. Negative significance was found between the experimental and control group on the effect of modality (H3). On measures of cognitive load, no statistically significant differences were found.

The Representation of Hispanic Females in Gifted and Talented and Advanced Placement Programs in a Selected North-Central Texas Public High School

Description: Analysis of a particular north-central Texas public high school revealed a strong representation of Hispanic females in advanced academic programs, i.e., AP and GT in proportion to their representation in the overall student population. Research seems to indicate that a progressive approach to academic-potential identification; culturally effective mentoring, traditional Hispanic values, and newly emerging personal and social characteristics all seem to be contributing factors. This study seems to indicate that a new type of Hispanic female is emerging who is more assertive academically, more visible in the classroom, and less marriage-and-family oriented as might be believed by teachers, society, their peers, and perhaps even their parents.

A Contravention of Established Principles of Interspecific Allometric Metabolic Scaling in Developing Silkworms, Bombyx Mori.

Description: Established interspecific metabolic allometric relationships do not adequately describe the complexity and variable physiological states of developing animals. Consequently, intraspecific allometric relationships of oxygen consumption and carbon dioxide production as a function of body mass; the respiratory quotient; the function of the silk cocoon; and body composition were investigated for each distinct developmental stage of the silkworm, Bombyx mori. Whole animal O2 consumption in Bombyx ranged from 0.00064 + 0.000047 ml O2 .hr-1 at larval instar I to 0.77 + 0.06 ml O2 .hr-1 in pre-pupal, falling to 0.21+ 0.01 ml O2 .hr-1 in the pupae. Those instars having a significant relationship between O2 consumption as a function of body mass, the slope of the line relating O2 consumption to body mass varied between 0.99 and 1.02, while across all instars the slope was 0.82. Developmental allometry should be presented for individual developmental stages because the individual allometric exponents of the stages can be significantly different from the overall allometric exponent throughout development and in some cases, the overall allometric exponent can be a statistical artifact. The first larval instar of Bombyx mori has the lowest cross sectional area of high metabolic tissue of the midgut (27%) and had one of the highest percentages of some metabolically inert tissues (i.e. lipid, 7.5%). Body composition of the first instar does not support the idea that smaller mass animals having the highest O2 consumption are composed of a greater percentage of metabolically active organs when compared to larger animals. However, this developmental stage has the highest percentage of the mitochondrial marker cytochrome oxidase, which correlates well with the high O2 consumption rate of the smaller mass. Therefore, established interspecific principles should not be assumed to function as valid models for intraspecific developmental relationships of metabolism as a function of body mass. Developmental …

Establishing genetic and physiological baselines for the black-tailed prairie dog (Cynomys ludovicianus).

Description: The black-tailed prairie dog (Cynomys ludovicianus) has experienced dramatic declines over much of its historical range due to habitat loss, plague, poisonings, and shootings. Many populations now occur as isolated genetic relicts. A multiple locus genetic profile was obtained using microsatellite analyses of six polymorphic nucleotide repeats from 319 black-tailed prairie dogs collected from 16 colonies throughout the state of Texas. This assessment revealed that existing populations have sufficient variation at all six loci to verify the usefulness of this approach as a primary genetic tool in conservation and preservation. The data reveals regional-dependent frequency patterns as well as support for founder/bottleneck effects for several of the 16 sites. Although the prairie dog population in Texas as a whole may appear genetically diverse, considerable genetic divergence has already occurred among the subpopulations (FST = 0.164). Isolation by distance is supported by genic differentiation analysis (P < 0.001) and pairwise correlation analysis between genetic distance and geographic distance (P < 0.001). Prairie dogs from six (COC, LUBA, LUBC, LUBD, LUBE, and TAR) of the original 16 sites have been relocated or exterminated, or were in the process of being relocated. Results indicated the following colonies (COT, DAL, HOW, and HUD) are of sufficient size and possess ample genetic diversity to be characterized as candidate foundation populations for future preservation efforts. The proximity of small colonies (< 20 hectares) such as HEMB, LUBB, and PEC, to other colonies should be examined to determine if they are isolated or part of a metapopulation. Colonies (HAR, HEMA, and SCH) with low genetic diversity would be ideal candidates for supplementation. Alternatively, these colonies could be relocated or blended with other similar but genetically distinct colonies. Baselines for healthy, pet prairie dog hematology and blood chemistries were also established. Results signify that data gathered from pet …

Comparison of Bare Root vs. Potted Plants, Species Selection, and Caging Types for Restoration of a Prairie Wetland, and Quantitative Analysis and Descriptive Survey of Plant Communities and Associations at Lewisville Lake Environmental Learning Area (LLELA), Lewisville, TX

Description: Lewisville Lake Environmental Learning Area (LLELA) is an 809-hectare property in Denton County, TX. A study of the vegetation community identified 466 species in 104 families, with 25% of the species from only two families, Asteraceae and Poaceae. The property demonstrates the characteristics of an early successional community, dominated by weedy species. Prairie communities are dominated by Johnson grass and ragweed, with climax tall grass prairie communities only in areas that have been planted with native grass seed. Forest communities are similarly in an early successional stage, dominated by the hackberry-elm-ash alliance, with small remnants of native Cross Timbers found in isolated patches. Species richness and diversity were highest in the forests and lowest in the wetlands; evenness, though not different across ecosystems, demonstrated a strong seasonal component. The species list was compared with previously reported lists for Denton County, and 256 species identified had not been previously reported for the county. A wetland restoration study was conducted to determine if there was a difference in survival and growth between potted transplants with intact root systems and bare-root transplants. Two different mesh sizes were used for protection, and the success of the different caging was evaluated. Of eight species, only four survived through the second growing season. There was no significant difference in the success of the propagule types for Sagittaria latifolia. The treatments planted with intact root systems showed significantly higher growth and reproduction than the bare-root treatments for Eleocharis quadrangulata, Heteranthera dubia, and Vallisneria americana. There was no survival recorded in the coarse mesh cages, likely due to the presence of crayfish that are able to get through the coarser mesh and feed on the transplants.

Theory of ordering transformations in metals and minerals

Description: This dissertation presents an investigation of ordering in FCC based systems using the pair potential approximation in the ground state and mean field limits. The theoretical approach is used to explain the occurrence of observed equilibrium phases and characteristics of thermodynamic instabilities, in particular, spinodal ordering and decomposition. It is shown that the stability of non-integer domain sizes in long period superstructures such as Al{sub 3}Ti and Ag{sub 3}Mg may result from the tendency of a system to reduce the number of non-dominant ordering waves, thus producing domain sizes that have rational fraction form n/m. This conclusion is used to explain the domain size stability with respect to variations in temperature and electron concentration. The cation ordering in the precipitate phases in calcite and dolomite is analyzed by analogy with ordering in FCC based metals. The ordered phases in calcite and dolomite are shown to be consistent with pair potential minima at {l brace}100{r brace} and {l brace}1/2, 1/2, 1/2{r brace} positions in reciprocal space respectively. 32 refs., 6 figs.

Perceptions of importance of diagnostic competencies among educational diagnosticians.

Description: This research was two-fold in its purpose: the first purpose being to assess the perceived relevance of the current state competency standards adopted in Texas by the State Board for Educator Certification (SBEC) as they apply to the work of the educational diagnostician and the second being to examine the diagnostician's perceived ability of training institutions to prepare professionals for the field of special education evaluation. This study examined the perceptions of educational diagnosticians (N = 432) through the use of a survey instrument. Specifically the survey instrument was designed to assess diagnosticians' perceptions of importance of the SBEC competencies to special education evaluation in general, and to their practice in particular; the frequency with which they use the competencies; and their degree of training to meet the demands of the competencies through their preparatory program. Results indicate variability with regard to the perceived importance of the competencies and the degree of preparation to meet the demands of the competencies in practice.

Around the Fibonacci Numeration System

Description: Let 1, 2, 3, 5, 8, … denote the Fibonacci sequence beginning with 1 and 2, and then setting each subsequent number to the sum of the two previous ones. Every positive integer n can be expressed as a sum of distinct Fibonacci numbers in one or more ways. Setting R(n) to be the number of ways n can be written as a sum of distinct Fibonacci numbers, we exhibit certain regularity properties of R(n), one of which is connected to the Euler φ-function. In addition, using a theorem of Fine and Wilf, we give a formula for R(n) in terms of binomial coefficients modulo two.

Interest Differentiation and Profile Elevation: Investigating Correlates of Depression, Confidence, and Vocational Identity

Description: Using a correlational design, this study examined relationships among and between differentiation, profile elevation, gender and educational level (predictors) and depression, confidence, and vocational identity (criterion). Clients presenting for counseling services (n = 90) with a career concern at a large, metropolitan university were included in the study. Six assumptions were examined using three single hierarchical regression analyses to reveal relationships among and between variables. Two research assumptions were confirmed at the .05 level of significance. Bivariate correlations were computed to examine the structure coefficients. Beta weights and structure coefficients were examined to determine the relative contribution of the predictors in the regression model. Results indicated that differentiation, profile elevation, gender and educational level did not predict significant variance in depression and vocational identity. However, differentiation, profile elevation, and educational level did significantly predict confidence (p< .0001).

An Analysis of Changes in Perceptions of Certified Athletic Trainers from 1996 to 2006 on the Women in Athletic Training Survey

Description: This study investigates how perceptions vary in athletic trainers regarding issues pertaining to women in the profession. Subjects included 1500 male and 1500 female certified athletic trainers who responded to 44 demographic and perceptions survey items used to determine whether perceptions were different based on the respondent's gender. Results were compared to a previously disseminated survey in 1996 to also determine if perceptions had changed from 10 years earlier. Results regarding the presentation of awards and the attainment of leadership positions in the organization were also compared to actual data collected. The data suggested that males perceptions had not changed, but females' perceptions had changed, in that females perceived that opportunities had improved. Data regarding the number of females who had ascended to leadership positions or had received awards did not support these perceptions, however, and female athletic trainers continue to struggle to obtain equality in both of these areas. Additionally, homosocial reproduction continues to influence the decreased number of women who are hired into various jobs, or advance into leadership positions, maintaining patriarchy in the athletics arena and in the athletic training organizations. Results suggested that because athletic training has been dominated by men since its inception, patriarchy continues to influence the lack of ascension of women into leadership positions and awards recognition. Many women are choosing to leave the profession due to the gender role pressure that they can not sustain a career in athletic training and raise a family. Men's professional sports continue to reject the concept of hiring women to serve as athletic trainers with their athletes, which also continues to preserve a patriarchal environment.

Latino success stories in higher education: A qualitative study of recent graduates from a health science center.

Description: This study used qualitative research, particularly life history analysis, to determine the personal pathways of success for Latino students who chose to enter a health science center for graduate study and who graduated. By giving voice to individual success stories of Latino students, some of the influences on the life pathways of these graduates were determined. For the purposes of this study, success was defined as graduation from a health science center with either a doctor of philosophy, doctor of public health or doctor of osteopathic medicine degree. Four research subjects agreed to participate in this study from a possible 11 students from the graduating class of 2004-2005 at this health science center. Data were gathered through multiple in-depth interviews of the students themselves over a period of no more than one month for each participant. Data were analyzed using the mind mapping technique and Padilla's unfolding matrix. Findings indicate that each participant traveled a different pathway to achieve educational success although similarities did exist across participants. The influences of family background, cultural background, educational background and personal perceptions and goals did affect the pathways of these four Latino graduates. While three of four participants indicated that family was the most important influence on their academic success, all participants related the importance of family to their success, although their definitions of family seemed to vary and included the concepts of education, culture, and personal perceptions and goals. The concepts of family support of education and a culture of education within the family unit emerged as similar themes among study participants. Other similarities among participants were a high academic self-concept, a strong internal locus of control, the ability to create academic community, and a positive view of potentially negative situations. Individual themes emerged from the narratives within each category for each …

Equity in Texas Public Education Facilities Funding

Description: The need to establish appropriate, adequate, and decent educational facilities for school children across the nation has been well-established. The ability of school districts in each state to build these facilities has varied widely in the past. Historically, most facilities funding ability for school districts has come from the local community and has been tied to property wealth and the ability of the community to raise significant tax dollars to pay for school buildings. Responding to an expanding need for increased facilities funding and school funding litigation, the state of Texas added facilities funding mechanisms for public school facilities construction in the late 1990s. The purpose of this study was to determine whether or not the methods of facilities funding were equitable in the state of Texas. In this study, equity values were framed around three equity concepts established in school funding equity literature. These three concepts were (1) horizontal equity defined as the equal treatment of equals, (2) vertical equity defined as the unequal treatment of unequals, and (3) wealth neutrality defined as the absence of a relationship between school district wealth and the equal opportunity of students. The sample comprised 1,039 school districts in the state of Texas. Well-established equity measures were administered to data including capital outlays, weighted per pupil capital outlays, instructional facilities allotments, and school district wealth. Horizontal equity measures included the McLoone index, the Verstegen index, the federal range ratio, and the coefficient of variation tests. The Odden-Picus Adequacy index (OPAI) was administered to determine levels of vertical equity. Finally, wealth neutrality was determined utilizing the Pearson product-moment correlation test. Findings indicated that there were poor horizontal equity levels both in the top half and bottom half of the distribution of capital outlay spenders. A coefficient of variation test was administered to determine overall …

A status and vision investigation of US university piano pedagogy programs.

Description: The two major research questions were: “What is the current status of 20 prominent piano pedagogy programs?” and “what is the vision of an ideal future piano pedagogy program from the perspective of 20 piano pedagogy leaders?” Subjects were the leaders of the top 20 US university piano pedagogy programs. A survey study with interview questions was used as the instrument for the study. The results showed that faculty, curriculum, and teacher training were three top factors that contributed to the quality of the programs. Most interviewed subjects held a doctoral degree in music. The curricular content and degree options were diverse across the selected programs. The content of teacher training included private and group teaching. The perceived best qualifications of a piano pedagogy instructor were to have a balanced education. Most programs had small or little to no budget, however, the preparatory program was perceived to be an enhancement to teacher training program finances. The greatest challenges were faculty acquisition and financial limitations. Gaining more money was the most common improvement priority for programs. To envision an ideal future piano pedagogy program, most leaders stated that an ideal program should contain encourage: (1) collaborating with other divisions' faculty members for developing a diverse curriculum, (2) providing multiple types of teacher training, (3) offering knowledge that is highly pertinent to students' future careers, (4) continually adjusting topics in the curriculum, and (5) utilizing all the possible resources to establish up-to-date facilities. The chief obstacle was a lack of money. However, finding a major donor, and developing a preparatory program to generate money may help to overcome the obstacles. Having administrators with positive attitudes toward pedagogy could help programs to gain more resources. Encouraging students to participate in workshops and conferences could enrich the training. Several recommendations may help emerging pedagogy …

Predicting Weight Loss in Post Surgical Laparoscopic Banding Patients

Description: The present study was a retrospective chart review (N=128) that investigated the efficacy of profiles derived from the three factors of the Eating Inventory® test (EI) - cognitive restraint, disinhibition, and hunger - to predict successful weight loss in post surgical laparoscopic banding patients at 6 and 9 months post surgery. Although the EI is commonly used in bariatric presurgical assessment, few studies have found consistent relationships between presurgical factor scores and subsequent weight loss in this population. Based on restraint theory, 7 profiles (high CR, super high CR, high D, super high D, high H, super high H, and null) were derived from the raw scores on the subscales of the EI and tested for weight loss predictive ability using direct logistic regression. Results were mixed with high CR, super high CR, and null profiles accurately predicting successful weight loss. Raw scores on the three factors (cognitive restraint, disinhibition, and hunger) were tested individually for predictive ability using direct logistic regression. Overall results indicated that the profile model accurately predicted more cases than the general factor model. This study significantly contributes to both the bariatric presurgical assessment literature and the restraint theory literature. Suggestions for future research are offered.

Examining the effects of scheduled course time on mathematics achievement in high school students.

Description: This study was designed to determine the effects of two different schedule types on mathematics achievement in public high school students. The instruments used included the Texas Assessment of Knowledge and Skills, given annually to all students in grades 3 through 11, the Texas Algebra I end-of-course examination, given as a district option to Algebra I students, and student final course grades as determined by classroom teachers. The study compared students' performance in these three areas during the 2004-2005 academic year in one suburban school district in North Texas. The study considers the type of schedule, either traditional or 8-block, between students in teachers' classes who teach the same course on both schedules concurrently. This study also investigates a qualitative aspect by including a short opinion survey of teachers' perceptions regarding student academic performance, teacher satisfaction and retention, and the ability to accomplish curricular goals. Findings from this research suggest course schedule does not have significant effects on student academic performance as measured using analyses of covariance comparisons with a 0.05 alpha-level, leading to the conclusion that a particular course schedule does not adversely impact student performance on academic measures. However, in some comparisons conducted within the course of the research, statistically significant results emerged. Qualitative data generated from a survey of teacher perceptions regarding the benefits of the two scheduling types, traditional 50-minute verses alternating day 8-block, suggested teachers preferred a traditional schedule over that of a block schedule design. Most teachers who responded to the survey instrument expressed the perception that traditional daily meeting classes allowed their students to be more successful. Additional research into the effects of scheduling types on students academic performance are suggested and would include examining larger population samples, a narrower study of specific courses within the field of mathematics, or an expansion of …

An investigation of beliefs and practices of conservative Protestant parents and the cultural applicability of child parent relationship therapy.

Description: The purpose of this study was to conduct a survey to identify the beliefs and practices of conservative Protestant parents, which assisted in clarifying the assertions in the current literature regarding conservative Protestant parenting. Additionally, this researcher sought to determine the applicability of child parent relationship therapy (CPRT), a filial therapy model based upon the principles of child centered play therapy, for conservative Protestant parents by ascertaining the need for cultural modifications. Beliefs and practices of conservative Protestants were measured using the Protestant Parenting Inventory (PPI), an original instrument developed through a series of focus groups and pilot testings. The population comprised 148 mothers and fathers from 4 Southern Baptist churches in and around the Dallas/Fort Worth metroplex. Exploratory factor analysis was applied to the data in order to increase internal consistency estimates and percent of explained variance. Criterion coding of demographic data allowed a multiple regression analysis to determine which demographic variables were significant predictors of participant responses on the PPI. Descriptive statistics allowed the researcher to investigate the compatibility of conservative Protestants and CPRT. Results of this study both confirm and refute past findings regarding conservative Protestants. Results also revealed the need for some cultural modifications to CPRT in order to make it an acceptable parenting resource for conservative Protestant parents.

History and Demise of The University Foundation in St. Augustine, Florida: An Institutional Autopsy

Description: This is an historical study of an institution of higher education that existed in St. Augustine, Florida from 1942-1949. The name of the institution was The University Foundation, founded by George J. Apel, Jr. This institution had several higher education divisions functioning under its umbrella. These divisions were the St. Augustine Junior College, the Graduate Division, the American Theological Seminary and the University Extension College with evening courses and Home Study courses for vacation study. The information collected for this study was accomplished primarily by the process of studying archives and conducting personal interviews. Since this is a qualitative research study, the collected information was processed through the use of multiple data-collection methods, data sources and analyses which insured the validity of the findings of the study. This process is known as information triangulation. The results of this study provide answers to the circumstances and identities of the key players which led to the formation of The University Foundation. Issues relating to the mission, revenue streams, faculty, curricula, and the ultimate demise of The University Foundation were also addressed in this study. Recommendations are included for higher education administrators, faculty, researchers, fund-raisers, and others whose efforts may be directed toward the launching and operation of new Christian institutions of higher learning.

Effects of Three Interventions with International College Students Referred for Adjustment and Language Difficulties: A Preliminary Study

Description: This quasi-experimental study examined the effects of three interventions with international college students referred for adjustment and language difficulties. Fifty-four international students were assigned to treatment groups including expressive group counseling (n = 14), group speech therapy (n = 14), interdisciplinary counseling/speech intervention (n = 13), and the no treatment control (n = 13). Three null hypotheses were analyzed using a two factor repeated measures analysis of variance to determine whether the four treatment groups behaved differently across time according to pre- and posttest results of the ASR Total and Internalizing Problems scales and the CCSR total scores. Two null hypotheses were rejected at the alpha .05 level of statistical significance with large treatment effects. Post hoc analyses were conducted when a statistically significant interaction effect was found. The no treatment control group was established as a baseline to examine how each intervention group performed over time when compared to the no treatment control group. Results of the post hoc analysis for Total Problems indicated that international students in all three treatment groups demonstrated statistically significant improvements in total behavior problems at the alpha .025 level (Expressive counseling: p = .002, Speech: p = .01, and Interdisciplinary: p = .003) and large treatment effects (partial η2 = .33, .24, and .31, respectively), thus indicating all three may be considered effective mental health treatments to target international students' total behavior problems. Results of the post hoc analysis for Internalizing Problems indicated that the interdisciplinary counseling/speech intervention was statistically significant (p = .02) in lowering internalizing problems and had a large treatment effect (partial η2 = .22). The expressive group counseling intervention also demonstrated a large treatment effect (partial η2 = .15) although not a statistically significant level (p = .04). The large treatment effects obtained for both interventions highlight the benefit …

The Reciprocal Dunford-Pettis and Radon-Nikodym Properties in Banach Spaces

Description: In this paper we give a characterization theorem for the reciprocal Dunford-Pettis property as defined by Grothendieck. The relationship of this property to Pelczynski's property V is examined. In particular it is shown that every Banach space with property V has the reciprocal Dunford-Pettis property and an example is given to show that the converse fails to hold. Moreover the characterizations of property V and the reciprocal Dunford-Pettis property lead to the definitions of property V* and property RDP* respectively. Me compare and contrast results for the reciprocal Dunford-Pettis property and property RDP* with those for properties V and V*. In the final chapter we use a result of Brooks to obtain a characterization for the Radon-Nikodým property.

The Characteristics and Properties of the Threshold and Squared-Error Criterion-Referenced Agreement Indices

Description: Educators who use criterion-referenced measurement to ascertain the current level of performance of an examinee in order that the examinee may be classified as either a master or a nonmaster need to know the accuracy and consistency of their decisions regarding assignment of mastery states. This study examined the sampling distribution characteristics of two reliability indices that use the squared-error agreement function: Livingston's k^2(X,Tx) and Brennan and Kane's M(C). The sampling distribution characteristics of five indices that use the threshold agreement function were also examined: Subkoviak's Pc. Huynh's p and k. and Swaminathan's p and k. These seven methods of calculating reliability were also compared under varying conditions of sample size, test length, and criterion or cutoff score. Computer-generated data provided randomly parallel test forms for N = 2000 cases. From this, 1000 samples were drawn, with replacement, and each of the seven reliability indices was calculated. Descriptive statistics were collected for each sample set and examined for distribution characteristics. In addition, the mean value for each index was compared to the population parameter value of consistent mastery/nonmastery classifications. The results indicated that the sampling distribution characteristics of all seven reliability indices approach normal characteristics with increased sample size. The results also indicated that Huynh's p was the most accurate estimate of the population parameter, with the smallest degree of negative bias. Swaminathan's p was the next best estimate of the population parameter, but it has the disadvantage of requiring two test administrations, while Huynh's p index only requires one administration.

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

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) and type of organization (public and private). Since most of the variables in the study were measured using nominal and ordinal scales, mostly non-parametric statistics were used for data analysis. The major finding from this study was that managers in Kuwait perceive positive effects of MNCs on change in Kuwait, with the exception of the cultural environment. The favorable perceptions were about the MNCs1 effects on the change in business, economic, and technological environments in Kuwait. The results of the study should be beneficial to the Kuwaiti government, MNCs doing business in Kuwait, and also to cross-cultural researchers interested in …
