Makara Human Behavior Studies in Asia

Presently, in Indonesia, the lack of a validated measure for obsessive–compulsive disorder (OCD) hinders diagnosis and treatment of the disease. The current study evaluated the reliability, validity, and optimal cut-off score of the Indonesian Florida Obsessive-Compulsive Inventory (FOCI) in predicting OCD presence. The participants included 384 adults: 157 with OCD, 80 case controls with anxiety or mood disorders, and 147 healthy controls. Assessments were conducted using FOCI, Obsessive-Compulsive Inventory-Revised, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7. Test–retest reliability of the FOCI was evaluated for over 2 weeks in 30 OCD patients. The internal consistency within OCD samples for the FOCI …

Jürgen Habermas Revisited Via Tim Cook's Wikipedia Biography: A Hermeneutic Approach To Critical Information Systems Research, Reilly Smethurst, Amber G. Young, Arial D. Wigdor

Information Systems Faculty Publications and Presentations

Critical Information Systems (IS) research is sometimes appreciated for the shades of gray it adds to sunny portraits of technology's emancipatory potential. In this article, we revisit a theory about Wikipedia’s putative freedom from the authority of corporate media's editors and authors. We present the curious example of Tim Cook's Wikipedia biography and its history of crowd-sourced editorial decisions, published on Wikipedia's talk pages. We use a hermeneutic method to subject the theory about Wikipedia's “rational discourse” and “emancipatory potential” to a soft, empirical test. When we examined Cook's Wikipedia biography and its editorial decisions, what we found pertained to …

Developing An Roi Assessment Model For Employee Development Programs Implemented By California Transit Agencies, Tyler Reeb, Susan Gallagher

Mineta Transportation Institute

The objective of this research is to determine the extent to which transit agencies in California are implementing Return on Investment (ROI) assessments or otherwise evaluating the value and effectiveness of the employee development programs they administer, what cost and performance data they collect and track, and what resources or support are needed to support ROI assessment efforts. Transit agencies will necessarily incur expenses in efforts to improve the recruitment, retention, and morale of employees, but will struggle to solicit adequate funding unless they are able to demonstrate the value of such efforts to a broader audience. Thus, developing and …

The Indirect Benefits Of A Transit Apprenticeship And Its Potential Value As A Flexible Postsecondary Pathway, Kathleen F. Mcconnell, Priya Raman

Mineta Transportation Institute

The transit sector has begun to embrace apprenticeships as a worthwhile training model. Apprenticeships may also address young people’s interest in career advancement opportunities, an additional benefit to the transit sector as it replaces an aging workforce and resolves other recruitment challenges. Apprenticeships that emphasize both technical and soft skills invest in career advancement by offering employees the chance to develop “cross-cutting competencies.” A highly developed model of this approach is found in the Santa Clara Valley Transportation Authority Joint Workforce Initiative (JWI), which formally recognizes skills acquisition with accredited certificates. Further development of this model would find support in …

The spanwise distance between the Ahmad body and the …

Right Turn On Red: Energy-Saving Measure Or Unsafe Maneuver?, Bruce Appleyard, Anurag Pande, Joseph Gibbons, Shams Tanvir, Megan Honey, Nell Ahangarfabrik, Mario Carbajal, Madison Swayne

Mineta Transportation Institute

There is a growing interest in prohibiting right turn on red (RTOR) policies in the name of pedestrian and bicycle safety but there is not enough research on the subject to help agencies make informed decisions. When Congress passed the Energy Policy and Conservation Act of 1975, they included a provision requiring states to permit right turns on red lights as an energy-saving measure to receive federal assistance for mandated conservation programs. Since 1980, all states have permitted right turns on red as a general rule. More research is needed to help guide state policies that can support jurisdictions in …

Mathematical Model For Helically Propagating Spatially Multiplexed Mimo Channels Inside Single Core Optical Fibers, Ibrahim Barka

Theses and Dissertations

It all started when our curiosity was sparked by observing light beams from a Multi-Channel Laser Source precisely coupled into a single-core optical fiber positioned on an optical bench in the lab. The multiplexed light beams, characterized by different spatial azimuthal angles, were guided by the fiber, tracing helical paths and producing a bright central spot with concentric rings depending on the launched angles, a phenomenon we came to call Spatial Domain Multiplexing (SDM). Conventional concepts of hybrid and LP modes couldn’t fully explain the behavior of SDM modes, leading us to the question of the types of field configurations …

Dissecting Metabolic Landscape Of Alveolar Macrophage, Sunayana Malla

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

The highly plastic nature of alveolar macrophage (AM) plays a crucial role in the defense against inhaled particulates and pathogens in the lungs. Depending on the signal, AM acquires either the classically activated M1 phenotype or the alternatively activated M2 phenotype. In this study, we investigate the metabolic shift in the activated phases of AM (M1 and M2 phases) by reconstructing context specific genome-scale metabolic (GSM) models. Metabolic pathways such as pyruvate metabolism, arachidonic acid metabolism, chondroitin/heparan sulfate biosynthesis, and heparan sulfate degradation are found to be important driving forces in the development of the M1/M2 phenotypes. Additionally, we formulated …

Challenging Myths & Addressing Intimate Partner Sexual Violence In Lgbtq+ Relationships, Nora K. Whitten

SPARK Symposium Presentations

Intimate partner violence (IPV), including intimate partner sexual violence (IPSV), is a public health crisis that disproportionately affects members of the LGBTQ+ community. This paper draws upon related, though limited, research to identify the five prevalent myths surrounding IPSV in LGBTQ+ relationships, addressing the following misconceptions: 1) IPSV can only occur in heterosexual relationships, 2) IPSV in LGBTQ+ relationships is not as severe, 3) Women cannot commit acts of sexual violence, 4) The more “masculine” partner is always the perpetrator, and 5) IPSV is a “mutual fight” among partners of the same sex. These myths perpetuate victim-blaming, minimize the severity …

Scavenging As An Accelerant In The Postmortem Interval Estimate: Refining Quantitative Regressions For Decomposition Analyses In Southeast Nebraska, Jenna L. Alexander

Department of Anthropology: Theses and Student Research

In forensic anthropology, the postmortem interval (PMI) is an estimation of the time elapsed from the moment of death to the point of discovery or examination. Contemporary approaches for estimating PMI have sought to refine broad quantitative regressions by addressing variance among intrinsic and extrinsic influences of decomposition at a regional level. Southeast Nebraska and the broader Great Plains region encompass one of the most influential agricultural ecosystems, featuring a unique climate type and a diverse spectrum of vertebrate scavengers. While there has been minimal research addressing how the biogeoclimatic conditions of Nebraska affect predicted estimates for PMI using known …

Exploring Variably Saturated Flow Formulations For Modflow: Implementing A Fully 3d Richards' Equation In Modflow 6, Sebastian Vazquez-Gasty

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

This thesis explores the implementation of a fully 3D Richards’ equation solution into MODFLOW 6 to solve for saturated/unsaturated flow. Currently, MODFLOW 6 has limited capability for solving unsaturated zone flow problems by using the Unsaturated Zone Flow (UZF) package, which neglects capillarity and assumes vertical 1-dimensional flow. Various formulations of the Richards’ equation were first evaluated for their strengths and weaknesses. Various numerical solution approaches to Richards’ equation were also studied to understand the robustness and efficiency of different approaches and to select one that would best fit into the MODFLOW 6 framework. The MODFLOW 6 framework was also …

Music And Narrative Memory, Maxwell Kayser

UNLV Theses, Dissertations, Professional Papers, and Capstones

Music can overlap with many activities, but its effects on our memory for those activities are not fully understood. The experiments here investigated the effects of calm and intense background music on both memory and narrative transportation (the feeling that one is absorbed into the events of a narrative) during reading. Participants read narratives either in silence or with background music and completed a measure of narrative transportation (Transportation Scale-Short Form; Appel et al., 2015). Participants were then tested, either in silence or with background music, on memory for explicit details and inferences from the narrative. Across both experiments, memory …

Self-Regulated Learning Through Self-Concordant Goals, Social Modeling And Sustainability Focus, Oana Mandrutiu-Iancu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research has shown that when students spend time reflecting and autonomously selecting their college goals, they show high intrinsic motivation, low extrinsic motivation and improvement in emotional and social adjustment over the first several months of college. Despite of this, it is estimated that 77% of first- and second-year students are undecided on their major and many remain undecided as they transition into their junior and senior year. Moreover, in education settings the primary emphasis is on academic success, but focusing solely on academic goals is limiting. As learning is inherently social, academic and social domains cannot be separated, while …
