Adaptive Underfrequency Load Shedding Based On Real Time Simulation, Mosab Salah Aldeen Mohamed Zeyada

Masters Theses and Doctoral Dissertations

Conventional Underfrequency Load Shedding (UFLS) is used to balance generation and load when underfrequency conditions occur. It sheds a fixed, predetermined amount of load irrespective of disturbance location. Several adaptive UFLS schemes are proposed in the literature. Recent research discussed utilizing synchrophasor messages to implement adaptive UFLS but these studies have been using virtual PMUs. Of late, hardware implementations for adaptive UFLS scheme using actual Phasor Measurement Units (PMUs) are reported but also these studies are based on small power systems. This study presents hardware implementation of adaptive UFLS based on real time simulation of IEEE39-bus system. The simulation tool …

Determinants Of Livelihood Choices: An Empirical Analysis From Rural Bangladesh, S Rahman, S Akter

School of Geography, Earth and Environmental Sciences

The study identifies socio-economic determinants of livelihood choices of rural households in Bangladesh (4,195 households from 139 villages) by applying a multinomial logit model of occupational choice and a multivariate Tobit model that allows for jointness in decision making. Results reveal that households choose multiple livelihood options. A number of socio-economic factors and resources at the household level as well as the state of rural infrastructure significantly determine households’ livelihood choice. Overall, resource-rich and educated households engage in diversified livelihoods and rural infrastructure promotes such diversification. Female-headed households fail to participate in any of the livelihood categories and consequently earn …

On The Limitations Of Using Situational Judgement Tests To Measure Interpersonal Skills: The Moderating Influence Of Employee Anger, Jerel E. Slaughter, Michael S. Christian, Nathan P. Podsakoff, Evan F. Sinar, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Many authors have suggested that situational judgment tests (SJTs) are useful tools for assessing applicants because SJT items can be written to assess a number of job-related knowledges, skills, abilities and other characteristics (KSAOs). However, SJTs may not be appropriate for measuring certain KSAOs for some applicants. We posit that using SJTs to measure interpersonal skills may lead to invalid inferences about applicants with higher levels of angry hostility (AH), and thus, AH should moderate the relation between interpersonally oriented SJTs and job performance. Three studies, using samples of healthcare workers (n = 225), police officers (n = 54), and …

Rethinking Governance In Management Research: From The Editors, Laszlo Tihanyi, Scott Graffin, Gerard George

Research Collection Lee Kong Chian School Of Business

In the field of management, the study of governance has primarily dealt with decision-making by boards of directors, chief executives, and senior managers. The corporate governance literature has generated important insights regarding incentive alignment, risk taking, and coordination challenges. Emerging trends, highlighted in this issue, raise new questions regarding managerial roles, organizational contexts, internal and social processes, and changes in governance over time. We encourage management scholars to rethink their approach to governance research by considering stakeholder engagement, the implications of big data, social impact, global dimensions, and comparative analysis of governance. A broadened conceptualization of governance may also deal …

Impact Of Guided Inquiry On Tenth Graders’ Understanding Of Chemical Bonds, Badreya Esmaeil Abdul Raheem Al Zarooni

Theses

Students' understandings of scientific conceptions have been of considerable interest to science education researchers and science teachers in recent years. Accordingly, many scholarly studies have been conducted on the students' understandings and misunderstandings, particularly, those concerned with chemistry. For the present study, the term misconception is used to encompass both alternative responses that arise from formal intervention; such as classroom study, as well as those resulted from the students own interactions with, and observations of their surrounding environment. The main purpose of this study is to investigate the understanding of the Grade-10 students about the concepts and misconception regarding the …

Reflections On Art, Nature And Technology: The Role Of Technology, Algorithm, Nature, Psyche And Imagination In The Aspiration Of An Aesthetic Experience, P Lopreiato

School of Art, Design and Architecture

There is something frustrating in the concept of algorithm that can even worry: its limitations. An algorithm does not need the time to define itself, it possesses in its structure everything that defines it and can work exclusively in a site, such as a computer, which is itself another finite system. Whenever a particular algorithm will be executed it will always be inexorably equal to itself because the number of possible states is finite. A logical­mathematical algorithm is essentially very different from a living being that reveals its being only in the passage of time, in the relationship with the …

Rpas And Non-International Conflict - A Strategic/Legal Assessment, Michael P. Kreuzer

Cardozo Law Review

Remotely Piloted Aircraft (RPAs) have, in recent years, been among the most controversial weapons systems in the U.S. war on terrorism. Debate rages over their overall effectiveness, their legality outside of recognized war zones, such as Afghanistan, and the precedent U.S. RPAs might set for other state and non-state actors in the future. Rather than focusing on the technology of the RPA platform itself, this Article argues that the RPA enables a type of war against individuals that exposes a significant hole in both international law and conventional understanding of the boundaries of warfare. Rather than focusing on treaties to …

Efficacy Of R&D Work In Offshore Captive Centers: An Empirical Study Of Task Characteristics, Coordination Mechanisms, And Performance, Deepa Mani, Kannan Srikanth, Anandhi Bharadwaj

Research Collection Lee Kong Chian School Of Business

Seizing the latest technological advances in distributed work, an increasing number of firms have set up offshore captive centers (CCs) in emerging economies to carry out sophisticated R&D work. We analyse survey data from 132 R&D CCs established by foreign multinational companies in India to understand how firms execute distributed innovative work. Specifically, we examine the performance outcomes of projects using different technology-enabled coordination strategies to manage their interdependencies across multiple locations. We find that modularization of work across locations is largely ineffective when the underlying tasks are less routinized, less analyzable, and less familiar to the CC. Coordination based …

Managing Value In Supply Chains: Case Studies On The Sourcing Hub Concept, Anupam Agrawal, Arnoud De Meyer, Luk N. Van Wassenhove

Research Collection Lee Kong Chian School Of Business

A firm’s raw material sourcing knowledge can be a strategic resource. This article explores how firms can capture and use this knowledge. It examines the sourcing experiences of four firms in four different countries in the automotive industry and identifies the raw material sourcing knowledge-related parameters. Synthesizing the findings from these case studies, it proposes the concept of the sourcing hub—a collaborative center involving the firm, its suppliers, and raw material suppliers—which can effectively capture and deploy the raw material sourcing knowledge for managing value in upstream sourcing.

The Institution Of Green: The Interaction Of Green Strategies And Key Stakeholders, Jennifer Martinez

Electronic Theses and Dissertations Archive

By empirically connecting the legitimization process with individual stakeholder groups, this research enhances our understanding of the impact of the institutional environment on organizational efforts toward sustainability, and suggests a new approach to examining the influence of stakeholders on green strategies.This dissertation consists of two papers. In the first paper, the role of consumers and the process of legitimization of the green organization is examined. Hypotheses are tested experimentally, wherein subjects consider a range of green organizational behaviors. Analysis reveals that all green behaviors result in the organization earning some legitimacy. Further, there is no significant difference in consumers' attitudes …

High-Frequency Gradiometry, Lauren Michelle Kendall

Electronic Theses and Dissertations Archive

Part 1: Two large explosions were recorded by a dense array of strong-motion accelerometers and rotational seismometers in northeastern Taiwan. The objective of this experiment was to test the response of the experimental Eentec rotational seismometers against calculated array rotations. Computed array rotation rates are seen to have little variation across the array, but point rotation rate measurements show significant deviations with each other and with the array rotation rates in the range of 3-5 Hz. It is not likely that the differences seen in the point and array-computed rotation rates are due to nonlinear or heterogeneous site conditions under …

Characterization And Role Of Msaabcr In Biofilm Development And Virulence In Staphylococcus Aureus, Gyan Sundar Sahukhal

Dissertations

Community-acquired, methicillin-resistant Staphylococcus aureus strains often cause localized infections in immune-compromised hosts, but some strains show enhanced virulence leading to severe infections even among healthy individuals with no predisposing risk factors. The genetic basis for this enhanced virulence has yet to be determined. S. aureus possesses a wide variety of virulence factors, the expression of which is carefully coordinated by a variety of regulators. Several virulence regulators have been well characterized, but others have yet to be thoroughly investigated. Previously, the msa gene as a regulator of several virulence genes, biofilm development, and antibiotic …

Orientations Of Low-Energy Domain Walls In Perovskites With Oxygen Octahedral Tilts, Fei Xue, Yijia Gu, Linyun Liang, Yi Wang, Long-Qing Chen

Materials Science and Engineering Faculty Research & Creative Works

Many applications of ferroic materials, such as data storage and spintronics, are achieved through the control and manipulation of their domain wall (DW) orientations and configurations. Here we propose a rotational compatibility condition to identify low-energy DWs in perovskites with oxygen octahedral tilt instability. It is derived from the strong DW energy anisotropy arising from the rigidity and corner-sharing feature of the octahedral network. We analyze quantitatively the DWs in SrTiO₃ and explain successfully the unusual ferroelectric DW width and energy in BiFeO₃.

Freedom, Benefit And Understanding: Reflections On Laurence Claus’S Critique Of Authority, John Finnis

San Diego Law Review

With wide-ranging and illuminating determination, Law’s Evolution and Human Understanding offers a refutation of the illusion of authority. No one, it rightly contends, has the right to be obeyed. Still less, as it correctly says, do any persons have the right that their say so be obeyed because they said so. Given the book’s stipulative definition of “authority,” these truths entail that authority is an illusion, and provide some important premises for a plausible further conclusion or pair of conclusions: it is harmful, both in practice and in theory, to say that some person or body has authority (“the rule …

On Bias In The Estimation Of Structural Break Points, Liang Jiang, Xiaohu Wang, Jun Yu

Research Collection School Of Economics

Based on the Girsanov theorem, this paper obtains the exact Önite sample distribution of the maximum likelihood estimator of structural break points in a continuous time model. The exact Önite sample theory suggests that, in empirically realistic situations, there is a strong Önite sample bias in the estimator of structural break points. This property is shared by least squares estimator of both the absolute structural break point and the fractional structural break point in discrete time models. A simulation-based method based on the indirect estimation approach is proposed to reduce the bias both in continuous time and discrete time models. …

United We Stand: The Possibilities Of Museums, Schools, And Anti-Bullying, Ashley Scotto

Seton Hall University Dissertations and Theses (ETDs)

In 2001, the National Institute of Child Health and Human Development (NICHD) described bullying as “widespread in American schools.” The results of an extensive survey throughout the United States revealed that over 16% of school children reported that they were recently bullied. As of 2013, the Kidsbridge Tolerance Museum in Ewing, New Jersey identified that over 30% of all students are involved in bullying as the bully, victim, or both. The comparison of the NICHD study and the statistics provided by the Kidsbridge Tolerance Museum indicate that bullying in the United States has increased within the past twelve years and …

Is Postpartum Depression A Disease Of Modern Civilization?, Jennifer Hahn-Holbrook, Martie Haselton

Psychology Faculty Articles and Research

Access to calorie-dense foods, medicine, and other comforts has made modern humans healthier than our prehistoric ancestors in many respects. However, the epidemics of obesity, diabetes, and cardiovascular disease suggest that there are also drawbacks to modern living. Here, we address the question of whether the dramatic cultural changes that have occurred over the past century have inflated rates of postpartum depression, adding postpartum depression to the list of diseases of modern civilization. We review evidence from cross-cultural, epidemiological, and experimental studies documenting associations between postpartum depression and modern patterns of early weaning, diets deficient in essential fatty acids, low …

Digital Behavior Intervention Plans: Effects On General Education Teacher Fidelity Of Implementation, Christopher G. Holcomb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Students with disabilities often have behavior that interferes with classroom learning. Serious problem behaviors are identified as the most significant factor interfering with learning in the classroom. Unfortunately, chronic behaviors often lead to a student dropping out of school. Current research typically focuses on areas of intervention for these students with little attention towards teacher fidelity of implementation of these interventions. Because of this, student's behavior intervention plans may not show effectiveness (e.g., progress monitoring, data driven decisions). It is important that researchers begin to explore systematic improvements in fidelity of implementation of behavior intervention plan components for general education …

Postural Sway And Brain Hemispheric Power Spectral Density Under Different Attentional Focus Conditions, Sharon Jalene

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to determine the differences, if any, in the root mean square error (RMSE) of postural sway and hemispheric power spectral density (PSD) in the alpha and beta bands (8-12Hz and 12-25Hz) during different conditions of attentional focus (i.e., internal focus (IF), and external focus (EF) and a control condition (C)). Previous studies have shown that the adoption of IF and EF significantly alter motor performance and that EF promotes automaticity (Wulf, 2013). Sports performance and balance studies utilizing EEG spectral analyses report increased alpha oscillations during expert performance and stable balance and increased beta …

An Examination Of Implicit Values In Cornerstone Student Affairs Textbooks, Nathan Slife

UNLV Theses, Dissertations, Professional Papers, and Capstones

The field of student affairs is properly cautious about indoctrination. Indoctrination, after all, clearly contradicts the field's ethical statements and standards. These cautions have led student affairs researchers to investigate explicit values in the field to prevent explicit forms of indoctrination. However, recent investigations of implicit values in the discipline of psychology have revealed a potential new source of indoctrination not currently studied in student affairs. Specifically, psychological researchers have identified a system of implicit values called liberal individualism that has been found to be pervasive throughout the psychological discipline. Given the widely acknowledged link between student affairs and psychology, …
