Can Small Farmers Survive?: Problems Of Commercializing The Milk Value Chain In Pakistan, Erum Sattar

Journal of Food Law & Policy

Milk in Pakistan is infused with the self-understanding of a nation. British colonial administrators laid the modern-day foundations of the country’s structure through land grants to small farmers. In an agricultural country where nearly forty percent of the population remains food insecure, rearing animals is a way of life in the rural areas where milk remains an important source of animal protein. Selling the daily surplus that families don’t consume is a significant source of earnings for cash poor families – and here an unprecedented change is taking place within dairy management and milk procurement systems. The scale of this …

Development Of Deterioration Models For Street Pavement In Dallas-Fort Worth Metroplex, Mladjan John Grujicic

Civil Engineering Dissertations - Archive

Accurate prediction of pavement deterioration is vital for an efficient and cost-effective allocation of available budgets for keeping an agency’s road networks operating at a desirable level. Currently, most cities in the Dallas-Fort Worth Metroplex area are using the software PAVERTM and the associated performance models to predict future conditions as they do not have available reliable prediction models. However, the problem with this type of modeling is that the models are not calibrated to local conditions. The Pavement Deterioration Prediction models that have been developed in this research will help any pavement management agencies within DFW Metroplex area to …

This dissertation focuses on the use of telemedicine for ambulance-based care for stroke patients, including how the design of this system impacts caregivers. The initial study investigated both the usability of a telemedicine system implemented in ambulances for stroke care as well as the possibility of human error when using it. The heuristic evaluation of usability violations …

Investigation Of The Thermal Performance Of Wall Systems With Significant Thermal Mass, Nathaniel Huygen

All Dissertations

There has been an effort over the last 30 years to reduce energy consumption and increase the efficiency of nearly everything that uses power. As the building sector utilizes a sizeable portion of the overall energy usage, increasing the efficiency of homes and office buildings is key to reduce energy consumption. One aspect of increasing energy efficiency in buildings is to reduce the heat loss through the building envelope. The thermal performance of wall systems requires testing in a hot-box apparatus. This thermal performance is usually denoted by the thermal resistance, or R-value of the system. This measurement, however, does …

An Examination Of Continuous Improvement In An Educational Organization, Billy Jacques Gira, Jennifer Malanga Martinez

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Continuous improvement (CI) is used across organizations to solve problems. Since the 2010s, CI practices have gained popularity in education. When comparing business organizations’ applications of CI practices to those in education, a gap is evident. Educational organizations create strategic plans, set long-term goals, implement initiatives, and measure overall outcomes in terms of student achievement. However, when attempting to build a high-performing culture and improve customer service between district departments and school centers, frequent and routine monitoring of customer experiences must occur.

This study examines current CI practices in a large, urban school district as they relate to improving the …

Incorporating Critical Thinking: Self-Perception Of Teachers’ Ability To Promote Critical Thinking Skills In Primary Grades (K-2), Courtney Milligan

Dissertations

The ability to think critically is a fundamental life skill and is an essential part of being a productive and contributing member of society. “Research shows that elements of critical thinking need to be taught explicitly” (Haber, 2020). The practice of developing critical thinking skills while students are initially "developing as thinkers" in primary grades is essential. According to Wagner (2008), his research finds that children should begin developing critical thinking skills as soon as they “are capable of abstract thinking” (p.17). Wagner (2008) argues that students need to develop these essential skills to effectively participate in our democracy and …

Polarization-Selective Modulation Of Supercavity Resonances Originating From Bound States In The Continuum, Chan Kyaw, Riad Yahiaoui, Joshua A. Burrow, Viet Tran, Kyron Keelen, Wesley Sims, Eddie C. Red, Willie S. Rockward, Mikkel A. Thomas, Andrew M. Sarangan, Imad Agha, Thomas A. Searles

Electro-Optics and Photonics Faculty Publications

Bound states in the continuum (BICs) are widely studied for their ability to confine light, produce sharp resonances for sensing applications and serve as avenues for lasing action with topological characteristics. Primarily, the formation of BICs in periodic photonic band gap structures are driven by symmetry incompatibility; structural manipulation or variation of incidence angle from incoming light. In this work, we report two modalities for driving the formation of BICs in terahertz metasurfaces. At normal incidence, we experimentally confirm polarization driven symmetry-protected BICs by the variation of the linear polarization state of light. In addition, we demonstrate through strong coupling …

A Qualitative Study Of Differences Among Hearing Parents In Positive Experiences Raising A Deaf Child: An Emergent Model Informed By Positive Psychology​, Amy Szarkowski, Patrick J. Brice

JADARA

The current qualitative study explored the positive, internal, and growth-enhancing experiences hearing parents derived from raising a child who is deaf or hard of hearing. Based on characteristics of parents’ process and outcomes of the parenting experiences, three distinct parent patterns were identified. Reflective Positive Parents reflected deeply about their experiences, quickly and easily identified positive experiences, and were open to making adjustments to meet their child’s needs. Engaged Parents contemplated their experiences, yet decisions about how to best support their children in many remained unresolved; this group identified both positive and negative aspects of parenting and attempted to align …

The Easternmost European Palaeolithic Artists: Iconography And Graphic Features At Kapova Cave (Southern Urals, Russia), Aitor Ruiz-Redondo, Katherin Yanovskaya, Vladislav S. Zhitenev

KIP Articles

Palaeolithic rock art is one of the most distinctive cultural traits of Upper Palaeolithic societies in Europe. Traditionally restricted to South-western Europe, especially to the Franco-Cantabrian province, in recent years, the geographic distribution of this phenomenon has noticeably expanded. Several years before these discoveries, the first decorated site found beyond southern Europe was Kapova cave, in Russia. This site, at the edge of the distribution area of European Palaeolithic art and far away from other cave sanctuaries, is key to define and understand potential long-distance cultural networks during the Upper Palaeolithic. In this paper, we present the first comprehensive inventory …

Emotional Presence In Building An Online Learning Community Among Non-Traditional Graduate Students, Mei Jiang, Katie Koo

Faculty Publications

The Community of Inquiry (CoI) framework posits that a collaborative online teaching and learning process can be achieved through three interdependent dimensions of presence: cognitive presence, social presence, and teaching presence. Emotion is considered an important factor in successful online learning. This study explored non-traditional graduate students’ perceived emotional presence that emerged in participants’ online learning experiences. Based on quantitative and qualitative data from 45 non-traditional graduate students in the field of education, the study showed that participants demonstrated both positive emotional expressions (e.g., enjoyment and happiness) and negative expressions (e.g., frustration and disappointment) in their responses. Emotional presence ratings …

On The Generation, Structure, And Semantics Of Grammar Patterns In Source Code Identifiers, Christian D. Newman,, Reem S. Alsuhaibani, Michael J. Decker, Anthony Peruma, Dishant Kaushik, Mohamed Wiem Mkaouer, Emily Hill

Articles

Identifier names are the atoms of program comprehension. Weak identifier names decrease developer productivity and degrade the performance of automated approaches that leverage identifier names in source code analysis; threatening many of the advantages which stand to be gained from advances in artificial intelligence and machine learning. Therefore, it is vital to support developers in naming and renaming identifiers. In this paper, we extend our prior work, which studies the primary method through which names evolve: rename refactorings. In our prior work, we contextualize rename changes by examining commit messages and other refactorings. In this extension, we further consider data …

Taxes As Pandemic Controls, Ashley C. Craig, James R. Hines Jr.

Articles

Tax policy can play important roles in limiting the spread of communicable disease and in managing the economic fallout of a pandemic. Taxes on business activities that bring workers or customers into close contact with each other offer efficient alternatives to broad regulatory measures, such as shutdowns, that have been effective but enormously costly. Corrective taxation also helps raise the revenue required to cover elevated government expenditure during a pandemic. Moreover, the restricted consumer choice that accompanies a pandemic reduces the welfare cost of raising tax revenue from higher-income taxpayers, making it a good time for deficit closure. Current U.S. …

The Linear Combination Of Kernels In The Estimation Of Cumulative Distribution Functions, Abdel-Razzaq Mugdadi, Rugayyah Sani

Applications and Applied Mathematics: An International Journal (AAM)

The kernel distribution function estimator method is the most popular nonparametric method to estimate the cumulative distribution function F(x). In this investigation, we propose a new estimator for F(x) based on a linear combination of kernels. The mean integrated squared error, asymptotic mean integrated squared error and the asymptotically optimal bandwidth for the new estimator are derived. Also, based on the plug-in technique in density estimation, we propose a data based method to select the bandwidth for the new estimator. In addition, we evaluate the new estimator using simulations and real life data.

Multilayer Security Of Rgb Image In Discrete Hartley Domain, Umar H. Mir, Deep Singh, D. C. Mishra, Parveiz N. Lone

Applications and Applied Mathematics: An International Journal (AAM)

In this article, we present RGB image encryption and decryption using random matrix affine cipher (RMAC) associated with discrete Hartley transform (DHT) and random matrix shift cipher (RMSC). The parameters in RMAC and RMSC phases act as two series of secret keys whose arrangement is imperative in the proposed algorithm. The computer simulations with results and examples are given to analyze the efficiency of the proposed approach. Further, security analysis and comparison with the prior techniques successfully supports the robustness and validation of the proposed technique.

An Efficient Algorithm For Numerical Inversion Of System Of Generalized Abel Integral Equations, Sandeep Dixit

Applications and Applied Mathematics: An International Journal (AAM)

In this article a direct method is introduced, which is based on orthonormal Bernstein polynomials, to present an efficient and stable algorithm for numerical inversion of the system of singular integral equations of Abel type. The appropriateness of earlier numerical inversion methods was restricted to the one portion of singular integral equations of Abel type. The proposed method is absolutely accurate, and numerical illustrations are given to show the convergence and utilization of the suggested method and comparisons are made with some other existing numerical solution.

Diminishing And Preventing Homelessness: A Managerial Audit Of Santa Clara County Nonprofit Organizations Addressing Homelessness, Sergio J. Gonzalez

Master's Projects

While the problem of homelessness intensifies in the United States, the search for solutions becomes increasingly crucial. As the number of homeless people in Santa Clara County, California continues to surge, various sections of government and nonprofit organizations have intensified their search for ways to reduce the problem. There have been many proposed ideas for a solution, such as policy options and emergency measures to address local crises. For example, the city of San Jose, California, has opened a “bridged housing” community, allocating 80 tiny homes with beds, a desk, and air conditioning in two locations to serve as temporary …

Who, What, Why & How: Reimagining State Constitutional Analysis In School Finance Litigation, William Thro

BYU Education & Law Journal

Despite the Supreme Court’s recognition of the importance of public education, America’s public schools remain ravaged by “savage inequalities”which lead to failure of the public schools.Because every State, except Hawaii, partially finances local public schools through local property taxes and because there are differences in the value of real property, there are vast disparities in available funding for local school districts. While every State Constitution requires the State Legislature to establish a public school system and while the State Legislatures have enacted a variety of statutes in an attempt to meet the state constitutional obligations, virtually every State has seen …
