“We’Re, Like, The Most Unhealthy People In The Country”: Employing An Equity Lens To Reduce Barriers To Healthy Food Access In Rural Appalachia, Kathryn Cardarelli, Emily M. Dewitt, Rachel Gillespie, Heather Norman-Burgdolf, Natalie Jones, Janet Tietyen Mullins

Dietetics and Human Nutrition Faculty Publications

Introduction

Obesity disproportionately affects rural communities, and Appalachia has some of the highest obesity rates in the nation. Successful policy, systems, and environmental (PSE) interventions to reduce obesity must reflect the circumstances of the population. We used a health equity lens to identify barriers and facilitators for healthy food access in Martin County, Kentucky, to design interventions responsive to social, cultural, and historical contexts.

Methods

We conducted 5 focus groups in Martin County, Kentucky, in fall 2019 to obtain perspectives on the local food system and gauge acceptability of PSE interventions. We used grounded theory to identify perceived barriers and …

Leadership, Contexts, And Learning - Part 2. Theories Of Learning, Channels, And Curricula, Larry M. Starr, Phd

School of Continuing and Professional Studies Faculty Papers

In this second of a two-part essay (see Starr (2020a1) for part 1) a systems-informed discussion of learning leadership is presented. I review the components of a system which consist of inputs, transformation, outputs, feedback and contextual environment, and argue that from a system perspective learning leadership emerges from interactions among elements particularly contextual variables. The concept of context is expanded to include the theory of learning applied, i.e., pedagogy, andragogy or heutagogy, and the communication channel used, i.e., face-to-face, virtual/online, or hybrid/blended. Learning leadership is also influenced by environmental context variables such as threats to health and safety, financial …

Evaluation Of A Supermarket Environmental Change Intervention: Findings From A Low-Fat Milk Couponing And Educational Marketing Pilot, Allison Karpyn, Barbara Ruhs, Ginnie Sawyer-Morris, Stephanie Weiss, Sara Grajeda, Donna Levine, Punam Ohri-Vachaspati

Journal of Human Sciences and Extension

The purpose of this study was to evaluate a multifaceted, collaborative approach to supermarket environmental change that included in-store couponing and educational marketing to increase low-fat milk purchasing across a 48-store supermarket chain serving predominately Hispanic customers. Point-of-sale (POS) and process data collected during the 16-week program implementation included in-store radio advertising, in-store signage, and POS coupons. POS data were analyzed by the coupon marketing partner, and a chi-square test was conducted to test for significant differences between groups. POS data indicated that 44,050 low-fat milk coupons were issued to traditional full-fat milk purchasing customers with a redemption rate of …

An Analysis Of The Effects Of Trauma On Foster Youth Aging Out Of The Florida Foster Care System: Implications For Supportive Interventions And Practices, Kesia Vazquez

Department of Conflict Resolution Studies Theses and Dissertations

In the U.S. there are approximately 25,000 youth that leave the Child Welfare System without a stable long-term housing arrangement and are left to age out of foster care and transition into adulthood (Dion, Dworsky, Kauff, & Kleinman, 2014, p. iii). These foster youth alumni (FYA) travel through various paths yet share many traumatic events that cause long-term effects that influence coping skills. This qualitative and phenomenological study aims to investigate the various traumas experienced, before and during foster care, and the coping skills that FYA have developed. A total of 16 FYA, from the Florida Child Welfare System, were …

Outage Probability And Throughput Analyses In Full-Duplex Relaying Systems With Energy Transfer, Jiaman Li, Le Chung Tran, Farzad Safaei

Faculty of Engineering and Information Sciences - Papers: Part B

In this article, we consider a dual-hop full-duplex (FD), amplify-and-forward, orthogonal frequency division multiplexing (OFDM) relaying network, where the relay operates based on a time-switching architecture to harvest energy from radio frequency signals. We use a polarization-enabled digital self-interference cancellation (PDC) scheme to cancel the self-interference signal at the relay in order to achieve FD communications. The paper provides a comprehensive analysis of the system performances in terms of outage probability and throughput over multipath Rayleigh fading channels. Furthermore, the optimal time split between the duration of energy harvesting and signal transmission to maximize the system throughput is numerically calculated. …

An Adaptive Feed-Forward Phase Locked Loop For Grid Synchronization Of Renewable Energy Systems Under Wide Frequency Deviations, Aravind Chellachi Kathiresan, Jeyaraj Pandiarajan, Asokan Sivaprakash, Thanikanti Sudhakar Babu, Md Rabiul Islam

Faculty of Engineering and Information Sciences - Papers: Part B

Synchronization is a crucial problem in the grid-connected inverter’s control and operation. A phase-locked loop (PLL) is a typical grid synchronization strategy, which ought to have a high resistance to power system uncertainties since its sensitivity influences the generated reference signal. The traditional PLL catches the phase and frequency of the input signal via the feedback loop filter (LF). In general, to enhance the steady-state capability during distorted grid conditions generally, a filter tuned for nominal frequency is used. This PLL corrects large frequency deviations around the nominal frequency, which increases the PLL’s locking time. Therefore, this paper presents an …

Model Predictive Control For A New Magnetic Linked Multilevel Inverter To Integrate Solar Photovoltaic Systems With The Power Grids, A M. Mahfuz-Ur-Rahman, Md Rabiul Islam, Kashem M. Muttaqi, Danny Sutanto

Faculty of Engineering and Information Sciences - Papers: Part B

The multilevel inverters are becoming increasingly popular for use in the grid integration of wind and photovoltaic (PV) power plants due to their higher voltage handling capability and the better output power quality. There are several types of multilevel inverters that have been proposed in the literature; among them the active neutral point clamp (ANPC) multilevel inverters have been drawing significant attention specially for solving the problems with other multilevel inverters. However, with the increase of number of levels, the ANPC requires more electronic switches and flying capacitors, by which the complexity and the cost increases. In this paper, an …

Beam-Based Analog Self-Interference Cancellation In Full-Duplex Mimo Systems, Anh Tuyen Le, Le Chung Tran, Xiaojing Huang, Y. Jay Guo

Faculty of Engineering and Information Sciences - Papers: Part B

Self-interference (SI) cancellation for full-duplex (FD) multiple input multiple output (MIMO) systems is challenging due to both hardware and signal processing complexity. In this paper, a beam-based adaptive filter structure with analog least mean square (ALMS) loops is proposed to significantly reduce the complexity of SI cancellation for FD MIMO systems. With this structure, the number of adaptive filters required for SI cancellation scales linearly with the number of transmit beams rather than quadratically with the number of antennas. Furthermore, to avoid additional transmit chains used to upconvert the beam signals to generate reference signals for the ALMS loops, a …

The Great Turning: A Call For Systems-Thinkers, Gabriella M. Demarce

Undergraduate Theses, Professional Papers, and Capstone Artifacts

David Orr, in an article on ecological intelligence reminds us that the modern world was shaped by people who did not understand that our social and economic systems could not coexist with the rest of the biological or natural systems on Earth (Orr, 1994). My research is rooted in Orr’s argument and discovering ways to shift this degrading paradigm. With my belief in the power of education in empowering youth and my background in environmental and climate change studies, I see a future in great need of people who holistically understand the functions of all types of systems and can …

Uncertainty And Support For Extremist Governments, Dennis Estrada

Cal Poly Humboldt theses and projects

Extremist governments and regimes have risen to power throughout history and the 2016 U.S. presidential election of Donald Trump raised concerns amongst scholars and politicians that the U.S. government is trending in this direction. Arguably questionable actions conducted by the Trump administration, such as the “Muslim Ban” or the inhumane treatment of migrants at the U.S. border, can be considered extremist in nature and at minimum they mimic the actions of extremist governments. What drives a populace to support extremist governments, particularly a populace raised in democracy? Previous literature and research suggests that under conditions of uncertainty, people are motivated …

The Politics Of Decentralizing Criminal Justice Systems In Postconflict Societies: Insights From Liberia (2011-2017), Samuel Opoku-Agyakwa

Walden Dissertations and Doctoral Studies

After the end of Liberia’s brutal 14 year civil war, the process of rebuilding Liberia has focused on a number of interventions including reforming the criminal justice system. In the current study, institutional, policy, legal reform, and infrastructure development were the approaches used to decentralize Liberia’s Criminal Justice System. Thirty experts were interviewed, and their responses coded using NVivo 12.0. Seven themes and 25 subthemes emerged from the data. It was that found that a top down internationally led approach with minimal involvement of local communities and the neglect of the traditional justice system characterized the decentralization process. Results also …
