The Theory Of Planned Behavior And Sleep Opportunity: An Ecological Momentary Assessment Of Intra-Individual Variability, Michael Phillip Mead

Psychology

Insufficient sleep duration is associated with poor physical and mental health outcomes, and many Americans report that they are not meeting sleep duration recommendations. Many individuals choose to restrict their own sleep, yet little is known about the source of this sleep deficit. Recent research efforts have used the Theory of Planned Behavior (TPB) to predict sleep health behavior. However, this research is limited in that it fails to measure volitional sleep behavior and focuses exclusively on between-person differences. This study addressed these limitations by using an intensive longitudinal design to test how constructs of the TPB relate to nightly …

The Application Of Active And Passive Optical Sensors In Natural Resource Decision Making, Donald Vincent Veverka

Natural Resources Management

Remote sensing is becoming a significant tool utilized to study vegetation health and abundance. Vegetation indices (VIs) generated by active and passive remote optical sensors can be implemented in natural resource and agricultural decision-making processes. One such use of vegetation indices is to predict yield and protein contents for various crops. However, the application of VIs is limited due to land use differences and the time period when remote sensing information is most accurate. A literature search was conducted on VIs paying attention to how those are used with sensors mounted on small unmanned aerial vehicles (sUAV). The search found …

Fracture Resistance Of Simulated External Cervical Resorption In Anterior Teeth Restored With And Without A Fiber Post., Michelle M. Romeo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: External cervical resorption (ECR) is a destructive type of external resorption that can be difficult to treat. ECR usually begins subgingival at the cementoenamel junction of teeth and continues apically and circumferentially. This substantial loss of tooth structure may make these teeth more prone to fracture and should be addressed when treatment planning teeth with ECR. The aim of this in vitro study was to evaluate the fracture resistance of treated and non-treated teeth with simulated ECR using two different treatment modalities.

Materials and Methods: Forty-eight extracted human permanent mandibular central incisors were selected. Teeth were randomly divided into …

Literature Review On Modeling Of Density Difference Pumping Strategy For Geothermal Applications, Lucas A. Ware

Graduate Theses, Dissertations, and Problem Reports (ETD)

The utilization of geothermal ground heat sources has been demonstrated at both large and small scales across the world. However, methods of extraction of the hot working fluids are often a source of energy inefficiency and high capital expense. Current techniques to extract geothermal fluids rely on mechanically and electrically driven down-hole components that require maintenance on a regular basis. In providing a solution, one approach that reduces complexity, decreases maintenance, and allows access to fluids at greater depth is an airlift approach. The airlift approach relies on injection of gas at a depth within a geothermal well to lift …

A Scenario-Based Parametric Analysis Of The Army Personnel-To-Assignment Matching Problem, Matthew D. Ferguson, Raymond R. Hill, Brian J. Lunday

Faculty Publications

This study aims to compare linear programming and stable marriage approaches to the personnel assignment problem under conditions of uncertainty. Robust solutions should exhibit reduced variability of solutions in the presence of one or more additional constraints or problem perturbations added to some baseline problems.
Several variations of each approach are compared with respect to solution speed, solution quality as measured by officer-to-assignment preferences and solution robustness as measured by the number of assignment changes required after inducing a set of representative perturbations or constraints to an assignment instance. These side constraints represent the realistic assignment categorical priorities and limitations …

Interpreting Intelligence Test Scores In Forensic Mental Health Assessments: Conceptual And Psychometric Considerations For “Intelligent” Testing, James R. Andretta, Ryan J. Mcgill

Archives of Assessment Psychology

The assessment and interpretation of intelligence tests and intelligence test scores are featured in many forensic mental health assessments (FMHA). Given the role these instruments play in adjudicating legal decisions for individuals (i.e., Atkins cases), it is critical that the scores possess adequate reliability and validity. Unfortunately, a growing body of empirical literature has raised significant psychometric and conceptual concerns about the integrity and clinical utility of IQ test part- and subtest-level scores. Apprehension has also been raised regarding the use of cognitive profile analysis interpretive methods such as the popular “Intelligent Testing” (IT) framework, which emphasize primary interpretation of …

Exploratory Factor Analysis Of The Repeatable Battery For The Assessment Of Neuropsychological Status (Rbans) In Adult Patients With Acquired Brain Injury And Brain Disease, Samuel T. Gontkovsky, David S. Kreiner, Joseph J. Ryan

Archives of Assessment Psychology

Research has offered limited support for the theoretically derived, five-factor structure of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). This investigation examined the structure of the RBANS using an exploratory factor analytic approach in a clinical sample of 248 adult patients with acquired brain injury/disease. Extraction using maximum likelihood method and subsequent orthogonal rotation yielded a two-factor model for the data, the first factor largely involving memory and the second factor emphasizing visual-spatial perception. Neither factor was pure, however, and both appeared to involve at least some degree of information processing speed. Consistent with many prior investigations …

Psychology Faculty Research and Scholarship

Racial discrimination contributes to stress-related health disparities among African Americans, but less is known about the acute effects of racial exclusion on the hypo-pituitary-adrenocortical response and psychological mediators. Participants were 276 Black/African American emerging-adults (54% female; Mage = 21.74, SD = 2.21) who were randomly assigned to be excluded or included by White peers via the game Cyberball. Racial exclusion (vs. inclusion) predicted: greater negative affect (F(1, 276) = 104.885, p < .0001), lower perceived control (F(1, 276) = 205.523, p < .0001), and greater cortisol release (F(1, 274) = 4.575, p= .033). Racial exclusion’s impact on cortisol release was mediated by lower perceived control …

Killing Them To Save Us’: Lessons From Politicide For Preventing And Countering Terrorism, Clark R. Mccauley

Psychology Faculty Research and Scholarship

This chapter reviews and extends the analysis of mass political murder advanced by Chirot and McCauley, then applies this analysis to understanding and countering terrorism. The justification for this application is that both politicide and terrorism target civilians in the context of asymmetric conflict. Three generalizations emerge. Politicide and terrorism cannot be understood or countered without (i) studying both sides in the conflict, (ii) separate studies of leaders, perpetrators, and mass sympathizers, and (iii) acknowledgment of the threats and grievances perceived by both sides. The chapter concludes with implications for fighting the war of ideas against jihadist and right-wing terrorists.

Distributed Strategy For Power Re-Allocation In High Performance Applications, Vaibhav Sundriyal, Masha Sosonkina

Electrical & Computer Engineering Faculty Publications

To improve the power consumption of parallel applications at the runtime, modern processors provide frequency scaling and power limiting capabilities. In this work, a runtime strategy is proposed to distribute a given power allocation among the cluster nodes assigned to the application while balancing their performance change. The strategy operates in a timeslice-based manner to estimate the current application performance and power usage per node followed by power redistribution across the nodes. Experiments, performed on four nodes (112 cores) of a modern computing platform interconnected with Infiniband showed that even a significant power budget reduction of 20% may result in …

Publications and Research

During the Fall 2017 semester, staff at the Hudson County Community College (HCCC), Library began to notice that many books listed as available in the catalog were often not being found on the shelves when patrons attempted to retrieve them. This situation puzzled library leadership because HCCC had recently conducted an inventory and removed all missing items from its holdings. To determine the cause of this discrepancy, HCCC staff decided to sample the library’s collection to determine if books were available at the expected locations. From this, the library found that a high percentage of its books were not present …

Evolving Into The Open: A Framework For Collaborative Design Of Renewable Assignments, Stacy Katz, Jennifer Van Allen

Publications and Research

Open pedagogy reconceives the notion of who creates knowledge and provides a pathway to empower students as creators. Leveraging open education resources in the classroom results in numerous benefits for students, including free access to knowledge, a participatory culture, and opportunities for innovation and creativity (Hegarty, 2015). Open pedagogical design often results in renewable course assignments, which empower students to create authentic resources that can be positioned to have greater impact through time, space, and gravity, particularly as they have longevity, reach, and value (Seraphin et al., 2018). In this chapter, we will highlight a collaborative partnership between library and …

Coronavirus, Civil Libertities, And The Courts: The Case Against Suspending Judicial Review, Lindsay Wiley

Scholarly Articles in Law Reviews & Journals

Introduction: For obvious reasons, local and state orders designed to help “flatten the curve” of novel coronavirus infections (and conserve health care capacity to treat coronavirus disease) have provoked a series of constitutional objections — and a growing number of lawsuits attempting to have those orders modified or overturned. Like the coronavirus crisis itself, much of that litigation remains ongoing as we write this Essay. But even in these early days, the emerging body of case law has rather elegantly teed up what we have previously described as “the central (and long-running) normative debate over emergency powers: Should constitutional constraints …

Social Media Platforms In International Criminal Investigations, Rebecca Hamilton

Scholarly Articles in Law Reviews & Journals

In the summer of 2017, hundreds of thousands of videos of the Syrian conflict suddenly disappeared from YouTube. The videos had been published on channels like the Aleppo Media Center, the Shaam News Agency, and the Violations Documentation Center in Syria, which are run by Syrian civil society groups that have been documenting war crimes and other human rights violations since the conflict began in 2011. In a war zone that has been extraordinarily difficult for outside investigators to access, the videos provided crucial evidence that many hoped would eventually lead to international criminal prosecutions. One can readily imagine that …
