Improving Irt Parameter Estimates With Small Sample Sizes: Evaluating The Efficacy Of A New Data Augmentation Technique, Brett P. Foley

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The 3PL model is a flexible and widely used tool in assessment. However, it suffers from limitations due to its need for large sample sizes. This study introduces and evaluates the efficacy of a new sample size augmentation technique called Duplicate, Erase, and Replace (DupER) Augmentation through a simulation study. Data are augmented using several variations of DupER Augmentation (based on different imputation methodologies, deletion rates, and duplication rates), analyzed in BILOG-MG 3, and results are compared to those obtained from analyzing the raw data. Additional manipulated variables include test length and sample size. Estimates are compared using seven different …

Is The Export-Led-Growth Hypothesis, Valid For Egypt? A Time Series Approach, Nagwa Khashaba, Abdelhamid Mahboub, William Latham, Mostafa Aboelsoud

Economics

This research addresses important empirical questions regarding the relationship between Egyptian exports and Egyptian economic growth by extending the Dirtsakis’s model (Dritsakis, 2004, p. 1834) with the addition of the labor force into the model. The hypothesis to be tested is, does export expansion cause economic growth in Egypt? In other words, is the Export-Led-Growth (ELG) hypothesis valid for Egypt?

This study analyzes the issue of ELG hypothesis in Egypt using the VAR analysis, quarterly time-series data over the period 1991:q1-2009:q4. The results tend to favor the effectiveness and validity of the ELG hypothesis for Egypt.

Centennial Hills Active Adult Center Business Plan, K. C. Brekken, Jeff Buchanan, David Gordon, Doug Guild

UNLV Theses, Dissertations, Professional Papers, and Capstones

The economic indicators for the state of Nevada indicate a bleak financial future. The foreclosure rate of the Las Vegas Valley is five times the national average and the highest rate in the country (Hoak, 2010). Sales tax revenues continue spiraling down and fell by 6.6 percent in December 2009 from December 2008 (Garcia, 2010). State politicians face an estimated budget deficit of $3.5 billion. Local conditions are equally dire. The City of Las Vegas faces a budget shortfall of nearly $69 million for this fiscal year (Choate, 2010). City administrators struggle to find creative solutions to fill financial gaps …

Supporting Transition-Aged Youth: One State's Efforts, L. Kris Gowen

School of Social Work Faculty Publications and Presentations

Young adults need specialized services as they age out of children’s mental health care and into adult services. Starting in 1997, Connecticut began to address this need by creating a Young Adult Services (YAS) program, designed to assist those over 18 who had moderate to severe symptoms of mental illness. YAS provides comprehensive service delivery that includes clinical, residential, case management, vocational, and social rehabilitation supports. Major principles that guide the YAS program include: (1) services must be comprehensive and integrated—focusing on one issue without supporting a young adult in other aspects of his or her life is ineffective; (2) …

Perception Of Ecological Risk To Water Environments And How It Affects Water Consumption And Water Resource Management In Southern Nevada, Tanju Kiriscioglu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate is harsh in southern Nevada where there is (and has been) a drought alert in effect for over a decade now (Kerr, 2007; Southern Nevada Water Authority, 2009). Las Vegas Valley is a major center of population in the region (1.9 million people), receiving only 4.5 inches of average annual precipitation yet in need of securing more water resources in the near future (SNWA, 2009). Water resource management in southern Nevada is a challenge, especially when 90% of the area’s water needs are met by a single source, the Colorado River, the flow rates of which have been in …

Do Psychology Researchers Tell It Like It Is? A Microgenetic Analysis Of Research Strategies And Self-Report Accuracy, David F. Feldon

Instructional Technology and Learning Sciences Faculty Publications

Acquiring research skills is considered to be a highly challenging aspect of developing expertise in the social sciences. Because instruction and mentoring in these skills are typically grounded in the self-report of researchers, difficulties in learning the material may be due to the content and accuracy of these explanations. Using a mixed-method, microgenetic design, this study examines the explanations of problem-solving processes by researchers along a continuum of expertise during simulated experiment design and subsequent data analysis. Findings indicate that participants’ self-explanations are largely inaccurate. Further, frequency of inaccurate statements is positively associated with the frequency of abstract cognitive processes, …

Infants And Children With Hearing Loss Need Early Language Access, P. Kushalnagar, G. Mathur, C. J. Moreland, Donna Jo Napoli, W. Osterling, C. Padden, C. Rathmann

Linguistics Faculty Works

Around 96 percent of children with hearing loss are born to parents with intact hearing, who may initially know little about deafness or sign language. Therefore, such parents will need information and support in making decisions about the medical, linguistic, and educational management of their child. Some of these decisions are time-sensitive and irreversible and come at a moment of emotional turmoil and vulnerability (when some parents grieve the loss of a normally hearing child). Clinical research indicates that a deaf child's poor communication skills can be made worse by increased level of parental depression. Given this, the importance of …

Recognizing Indians: Place, Identity, History, And The Federal Acknowledgment Of The Ohlone/Costanoan-Esselen Nation, Philip Blair Laverty

Anthropology ETDs

Long considered extinct,' in 1992 the Ohlone/Costanoan-Esselen Nation (OCEN) began its bid to achieve federal acknowledgment as an American Indian tribe. This dissertation is a study of the history of the Native peoples of the Monterey Bay region and the current recognition efforts of OCEN. Using ethnographic and ethnohistorical methodologies and the fieldnotes of John Peabody Harrington as a key archive, it focuses on social and cultural aspects of identity change and community persistence, particularly in relation to land and place. It explores contemporary understandings of precontact political organization as they presently affect the Esselen Nation in the context of …

The Chilean Left In Power: Achievements, Failures, And Omissions, Evelyne Huber, Jennifer Pribble, John D. Stephens

Political Science Faculty Publications

In his introduction to this volume, Weyland locates the administrations of Socialist Presidents Ricardo Lagos (2000-06) and Michelle Bachelet (2006- 2010) closest to the moderate pole among current leftist governments in Latin America. We concur and hope to contribute to the discussion by elucidating the sources of this moderation and examining the performance of these governments in the areas of political management, economic policies, and social policies and labor market reforms. The Lagos and Bachelet governments have pursued similar market-friendly economic policies to their predecessors. Although both presidents have made important progress in overcoming the political institutionallegacies of Augusto Pinochet's …

Does Context Matter In Determining Psychological Abuse? Effects Of Pattern, Harm, Relationship, And Norms, Dana D. Dehart, Diane R. Follingstad, Alice M. Fields

Faculty and Staff Publications

This study explored contextual influences in determining whether psychologically aggressive actions constitute abuse. One hundred and thirty-one undergraduates completed measures of key experiences, attitudes, and traits, and rated abusiveness of behaviors in a series of vignettes. Vignettes varied contexts in which behaviors occurred, including whether the behavior was a pattern, whether there was harm to the recipient, characteristics of the initiator-recipient relationship, and whether behavior was normative. Results showed no effects for participants' gender, past experiences with psychological aggression, and traits or attitudes. Findings indicated that behaviors were rated as more abusive when harm to recipient was evident. Findings regarding …

Health And Growth: Causality Through Education, Rui Huang, Lilyan E. Fulginiti, E. Wesley Peterson

Department of Agricultural Economics: Faculty Publications

Purpose--The paper theoretically and empirically investigates the impact on human capital investment decisions and income growth of lowered life expectancy as a result of HIV/AIDS and other diseases. Design/methodology/approach--The theoretical model is a three-period overlapping generations model where individuals go through three stages in their life, namely, young, adult and old. The model extends existing theoretical models by allowing the probability of premature death to differ for individuals at different life stage, and by allowing for stochastic technological advances. The empirical investigation focuses on the effect of HIV/AIDS on life expectancy and on the role of health on educational investments …

System Dynamics Implementation Of An Extended Brander And Taylor-Like Easter Island Model, Takuro Uehara, Yoko Nagase, Wayne Wakeland

Complex Systems Faculty Publications and Presentations

We provide a system dynamics implementation of a dynamic ecological economics model. Dynamic economic models are often constrained to use functions, such as the Cobb-Douglas function, chosen “conveniently” to allow for analytic solutions. The C-D function, however, suffers from its fixed elasticity that does not allow for the substitutability between man-made capital and natural capital to change, which is vital for economic sustainability. Using system dynamics removes this constraint and enables more realistic ecological economics models containing functions not amenable to analytic solution. The base model is the natural resource and population growth model developed by Brander and Taylor (1998) …

"Some", And Possibly All, Scalar Inferences Are Not Delayed: Evidence For Immediate Pragmatic Enrichment, Daniel J. Grodner, N. M. Klein, K. M. Carbary, M. K. Tanenhaus

Psychology Faculty Works

Scalar inferences are commonly generated when a speaker uses a weaker expression rather than a stronger alternative, e.g., John ate some of the apples implies that he did not eat them all. This article describes a visual-world study investigating how and when perceivers compute these inferences. Participants followed spoken instructions containing the scalar quantifier some directing them to interact with one of several referential targets (e.g., Click on the girl who has some of the balloons). Participants fixated on the target compatible with the implicated meaning of some and avoided a competitor compatible with the literal meaning prior to a …

The study examined whether Google Scholar was able to find any links to full text, if open access versions of the articles were available and where these articles were being hosted. The results showed the archiving of articles is not a regular practice in the field, articles are not being deposited in institutional or subject repositories at a high rate and the overall the percentage of available open access articles in …

Investor Knowledge And Investment Barriers., Steven Doman

Student Works (2010-2019)

The world of investing in the various products related to the stock and bond markets is confusing for many people. This is a problem since financial investments often represent a large portion of an individual’s personal assets. As regulators begin to search for answers about what caused the economic crisis of 2008-2009 and try to pass regulations that will prevent it from happening again, investors will continue to look to the products of investment firms to help accomplish their financial goals. Unfortunately for investors, many will continue to choose investments based on very limited personal knowledge. Investment firms will in …
