Using Pratt's Importance Measures In Confirmatory Factor Analyses, Amrey D. Wu, Bruno D. Zumbo

Journal of Modern Applied Statistical Methods

When running a confirmatory factor analysis (CFA), users specify and interpret the pattern (loading) matrix. It has been recommended that the structure coefficients, indicating the factors’ correlation with the observed indicators, should also be reported when the factors are correlated (Graham, Guthrie, & Thompson, 2003; Thompson, 1997). The aims of this article are: (1) to note the structure coefficient should be interpreted with caution if the factors are specified to correlate. Because the structure coefficient is a zero-order correlation, it may be partially or entirely a reflection of factor correlations. This is elucidated by the matrix algebra of the structure …

A Double Ewma Control Chart For The Individuals Based On A Linear Prediction, Rafael Perez Abreu, Jay R. Schaffer

The relationships resulting from the dichotomization of multivariate normal data is a question that causes concern when using exploratory factor analysis. The relationships in an exploratory factor analysis are examined when multivariate normal data, generated by Monte Carlo methods, is dichotomized.

Power And Sample Size Estimation For Nonparametric Composite Endpoints: Practical Implementation Using Data Simulations, Paul M. Brown, Justin A. Ezekowitz

Journal of Modern Applied Statistical Methods

Composite endpoints are a popular outcome in controlled studies. However, the required sample size is not easily obtained due to the assortment of outcomes, correlations between them and the way in which the composite is constructed. Data simulations are required. A macro is developed that enables sample size and power estimation.

Some Remarks On Ricci Solitons, Ramesh Sharma, S Balasubramanian, N. Uday Kiran

Mathematics Faculty Publications

We obtain an intrinsic formula of a Ricci soliton vector field and a differential condition for the non-steady case to be gradient. Next we provide a condition for a Ricci soliton on a Kaehler manifold to be a Kaehler–Ricci soliton. Finally we give an example supporting the first result.

Efficacy Of North Haven’S Response To Intervention In Reducing Over-Identification Of Specific Learning Disabilities, Karyn B. Gallagher

EDL Sixth Year Theses

In 2006, a reauthorization of the Individuals With Disabilities Education Improvement Act led to changes in how the state of Connecticut determined special education eligibility for a student with a specific learning disability. The Response to Intervention (RTI) approach replaced of the discrepancy model in making this determination. This retrospective case study looked at the perceptions of North Haven Staff on the efficacy of the RTI process in reducing the over-identification of students with specific learning disabilities. A mixed-methods survey was administered to 337 professionals in North Haven, CT. Of the 86 responses received, 73 were determined to be useful …

The Influence Of Culturally Relevant Pedagogy In Mississippi Public Schools To Improve Adolescent African American Males' Literacy Achievement, Shawnese Davis

Dissertations

This study used a quantitative approach to measure Mississippi secondary teachers’ understanding and their extent of using culturally relevant pedagogy to increase students’ literacy performance, specifically African American males. The researcher identified school districts with 50% or more African American students. The data collected in this study was used to compare reading high growth (40%) school teachers’ use of culturally relevant pedagogical teaching approaches to determine if there was a statistically significant difference in their understanding and frequency of using culturally relevant pedagogy to increase students’ reading performance. A 38-statement survey instrument was adapted from McKinley’s Strategies and Behaviors of …

Mississippi Choices And The Influence Of Career And Technical Education, Charish Rene Pierce

Dissertations

Mississippi counselors serve in a variety of roles in order to meet the needs of all students. The role of the school counselor is to execute efforts to address each student’s academic, personal/social, and career development needs (ASCA, 2005). Middle and high school counselors are often tasked with activities that do not align with national and state standards for school counseling. Thus, these activities generate very little time for activities such as the Choices program and career development.

This study examined the middle and high school counselors’ usage of the Choices program. In addition, the research study explored middle and …

Historical Change Of Seagrasses In The Mississippi And Chandeleur Sounds, Linh Thuy Pham

Dissertations

Seagrasses are important coastal resources facing numerous stressors, and losses have been documented from local to global assessments. Under the broad theme of habitat loss and fragmentation, a study of historical change in total area and landscape configuration of seagrasses in the Mississippi and Chandeleur Sounds was conducted. Mapping data was collated from a multitude of previous projects from 1940 to 2011.

Comparisons of seagrass area among various studies that used different mapping methods can result in overestimation of area change and misleading conclusions of change over time. The vegetated seagrass area (VSA) data were generalized to a common resolution …

An Analysis Of Operant Conditioning And Its Relationship With Video Game Addiction, Daniel Vu

ART 108: Introduction to Games Studies

A report published by the Entertainment Software Association revealed that in 2015, 155 million Americans play video games with an average of two gamers in each game-playing household (Entertainment Software Association, “Essential Facts about the Computer and Video Game Industry”). With this massive popularity that has sprung alongside video games, the question must be asked: how are video games affecting today's people? With the current way some video games are structured, the video game rewards players for achieving certain accomplishments. For example, competitive video games reward players who achieve victories by giving them a higher ranking or other games display …

Quantum Econometrics: How To Explain Its Quantitative Successes And How The Resulting Formulas Are Related To Scale Invariance, Entropy, Fuzzy, And Copulas, Hung T. Nguyen, Kittawit Autchariyapanitkul, Olga Kosheleva, Vladik Kreinovich, Songsak Sriboonchitta

Departmental Technical Reports (CS)

Many aspects of human behavior seem to be well-described by formulas of quantum physics. In this paper, we explain this phenomenon by showing that the corresponding quantum-looking formulas can be derived from the general ideas of scale invariance, fuzziness, and copulas. We also use these ideas to derive a general family of formulas that include non-quantum and quantum probabilities as particular cases -- formulas that may be more adequate for describing human behavior than purely non-quantum or purely quantum ones.

Why Triangular Membership Functions Are Often Efficient In F-Transform Applications: Relation To Interval Uncertainty\\ And Haar Wavelets, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Fuzzy techniques describe expert opinions. At first glance, we would therefore expect that the more accurately the corresponding membership functions describe the expert's opinions, the better the corresponding results. In practice, however, contrary to these expectations, the simplest -- and not very accurate -- triangular membership functions often work the best. In this paper, on the example of the use of membership functions in F-transform techniques, we provide a possible theoretical explanation for this surprising empirical phenomenon.

How To Store Tensors In Computer Memory: An Observation, Martine Ceberio, Vladik Kreinovich

Departmental Technical Reports (CS)

In this paper, after explaining the need to use tensors in computing, we analyze the question of how to best store tensors in computer memory. Somewhat surprisingly, with respect to a natural optimality criterion, the standard way of storing tensors turns out to be one of the optimal ones.

Beyond Integration: A Symmetry-Based Approach To Reaching Stationarity In Economic Time Series, Songsak Sriboonchitta, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

Many efficient data processing techniques assume that the corresponding process is stationary. However, in areas like economics, most processes are not stationery: with the exception of stagnation periods, economies usually grow. A known way to apply stationarity-based methods to such processes -- integration -- is based on the fact that often, while the process itself is not stationary, its first or second differences are stationary. This idea works when the trend polynomially depends on time. In practice, the trend is usually non-polynomial: it is often exponentially growing, with cycles added. In this paper, we shod how integration techniques can be …

Why Sparse?, Thongchai Dumrongpokaphan, Olga Kosheleva, Vladik Kreinovich, Aleksandra Belina

Departmental Technical Reports (CS)

In many situations, a solution to a practical problem is sparse, i.e., corresponds to the case when most of the parameters describing the solution are zeros, and only a few attain non-zero values. This surprising empirical phenomenon helps solve the corresponding problems -- but it remains unclear why this phenomenon happens. In this paper, we provide a possible theoretical explanation for this mysterious phenomenon.

Infinite Free Resolutions And Blowup Algebras, Alessio Sammartano

Open Access Dissertations

This dissertation deals with questions concerning ideals and modules over graded or local noetherian commutative rings. The main results deal with the quantitative analysis of free resolutions, with particular emphasis on infinite ones, and with the structure of blowup algebras of certain determinantal ideals. In Chapter 3 we consider resolutions of ideals containing a regular sequence of powers of variables. Let S be a polynomial ring and R a complete intersection in S defined by pure powers of the variables. We prove that, in the Hilbert scheme parametrizing the closed subschemes of Proj(R) with a fixed Hilbert polynomial ℘, there …

The assessment builds upon existing soil-landscape mapping produced by van Gool and Kipling (1992), and Barnesby and Proulx-Nixon (2000). This report provides guidance to decision-makers and investors about areas with potential for irrigated horticulture.

The survey area for this assessment is east of Myalup, covering 37 800 hectares (ha). Johnston Road forms the northern boundary and the Brunswick River forms the southern boundary (Figure 1.1). The sandy soils of the …

Socializing With The Out-Group: Testing The Contact Hypothesis Among School Students In Bosnia And Herzegovina, Matthew Thomas Becker

Faculty and Student Publications

The purpose of this article is to test the contact hypothesis among self-identifying Bosniak, Croat, Serb, and Bosnian high school seniors in Bosnia and Herzegovina, using the Other-Group Orientation Scale (Roberts et al., 1999). This article finds that attending a ‘non-appropriate’ ethnic school statistically increases tolerance of out-group members, which conforms to the predictions of the contact hypothesis, originally put forth by Allport (1958). This field research also found that secondary schools are largely homogenous in the country, thus preventing high levels of cross-ethnic contact in schools, which was expected. This article represents the first post-war, countrywide quantitative testing of …

Investigating The Possible Effects Of State Takeover On Teacher Self-Efficacy In Low-Performing, Low-Ses School Districts In Arkansas, Pasty Ann Hughey

Theses and Dissertations from 2017

The purpose of this study was to investigate the differences in teachers’ level of self-efficacy based on the state takeover status of a school district. The design of this study was “group comparison research” (Gall, Gall, & Borg, 2015). The dependent variable was teachers’ level of self-efficacy and the independent variable was state takeover status. Data gathered for this study were teacher demographics and the level of teacher self-efficacy measured by the TSES instrument (Tschannen-Moran & Woolfolk Hoy, 2001). Three school districts in Arkansas were selected and matched on demographic variables and school academic measures. One district had recently been …

Changing Antimalarial Drug Sensitivities In Uganda, Stephanie Alexis Rasmussen

Dissertations, Masters Theses, Capstones, and Culminating Projects

Dihydroartemisinin-piperaquine (DP) has demonstrated excellent efficacy for the treatment and prevention of malaria in Uganda. However, resistance to both components of this regimen has emerged in Southeast Asia. The efficacy of artemether-lumefantrine, the first-line regimen to treat malaria in Uganda, has also been excellent, but continued pressure may select for parasites with decreased sensitivity to lumefantrine. To gain insight into current drug sensitivity patterns, ex vivo sensitivities were assessed and genotypes previously associated with altered drug sensitivity were characterized for 58 isolates collected in Tororo, Uganda from subjects presenting in 2016 with malaria from the community or as part of …
