Optimizing Incident Management Strategies Using Simulation, Anshuman Manori

Computer Science

Incidents, pre-programmed or random, are major sources of congestion on urban freeways. With many of urban freeways in the US operating close to capacity, the need to reduce the impact of incident-related congestion has become critical. Incident Management Strategies (IMS), when properly developed and deployed, have the potential to reduce such congestion on urban freeways. The purpose of this paper is to develop an analytic framework for the calibration and application of a -simulation model for testing the impact of alternate IMS on an urban transportation network. Initially a framework is presented in a conceptual form, and demonstrates the calibration …

Post-Coring Entrapment Of Modern Air In Some Shallow Ice Cores Collected Near The Firn-Ice Transition: Evidence From Cfc-12 Measurements In Antarctic Firn Air And Ice Cores, Murat Aydin, S. A. Montzka, M. O. Battle, M. B. Williams, Warren J. De Bruyn, J. H. Butler, K. R. Verhulst, C. Tatum, B. K. Gun, D. A. Plotkin, B. D. Hall, Eric S. Saltzman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

In this study, we report measurements of CFC-12 (CCl2F2) in firn air and in air extracted from shallow ice cores from three Antarctic sites. The firn air data are consistent with the known atmospheric history of CFC-12. In contrast, some of the ice core samples collected near the firn-ice transition exhibit anomalously high CFC-12 levels. Together, the ice core and firn air data provide evidence for the presence of modern air entrapped in the shallow ice core samples that likely contained open pores at the time of collection. We propose that this is due to closure of the open pores …

Interspecific Variation In Palatability Suggests Cospecialization Of Antipredator Defenses In Sea Hares, Kimberly K. Takagi, Nadia N. Ono, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Prey species often deploy different kinds of antipredator defenses, which can interact with each other in ways that are not yet completely understood. Much research into these interactions has utilized gastropod mollusks, usually focusing (in part) on the protective utility of the gastropod shell. This makes the evolutionary reduction of the shell in the opisthobranch gastropods (marine slugs) particularly interesting. This loss of protective function of the shell is associated with the evolution of alternative defenses. Particularly well studied are chemical defenses, especially those using secondary metabolites derived from food resources. As a first step toward understanding interspecific variation in …

Equal Bmd After Daily Or Triweekly Exercise In Growing Rats, B. D. Kayser, J. K. Godfrey, R. M. Cunningham, R. A. Pierce, S. V. Jaque, Ken D. Sumida

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The purpose of this study was to examine the efficacy of continuous resistance training (3 days/wk) compared to interrupted resistance training where 20-24 h separated an exercise bout (i.e. 6 days/wk) for enhancing bone mineral density (BMD) in growing male rats. The total volume of work performed per week between the two resistance training programs was equivalent by design. Young male rats were randomly divided into Control (Con, n = 9), 3 days/wk resistance trained group (RT3, n = 9), and 6 days/wk resistance trained group (RT6, n = 9). The RT3 and RT6 groups were conditioned to climb a …

Mine And Thine: The Territorial Foundations Of Human Property, Peter Descioli, Bart J. Wilson

ESI Working Papers

Research shows that many animal species have morphological and cognitive adaptations for fighting with others to gain resources, but it remains unclear how humans make fighting decisions. Non-human animals often adaptively calibrate fighting behavior to ecological variables such as resource quantity and whether the resource is distributed uniformly or clustered in patches. Also, many species use strategies to reduce fighting costs such as resolving disputes based on power asymmetries or conventions. Here we show that humans apply an ownership convention in response to the problem of severe fighting. We designed a virtual environment where ten participants, acting as avatars, could …

The Attack And Defense Of Weakest-Link Networks, Dan Kovenock, Brian Roberson, Roman M. Sheremeta

ESI Working Papers

This paper experimentally examines behavior in a two-player game of attack and defense of a weakest-link network of targets, in which the attacker‟s objective is to successfully attack at least one target and the defender‟s objective is diametrically opposed. We apply two benchmark contest success functions (CSFs): the auction CSF and the lottery CSF. Consistent with the theoretical prediction, under the auction CSF, attackers utilize a stochastic “guerilla warfare” strategy — in which a single random target is attacked — more than 80% of the time. Under the lottery CSF, attackers utilize the stochastic guerilla warfare strategy almost 45% of …

Prenatal Beta-Endorphin As An Early Predictor Of Postpartum Depressive Symptoms In Euthymic Women, Ilona S. Yim, Laura M. Glynn, Christine Dunkel Schetter, Calvin J. Hobel, Aleksandra Chicz-Demet, Curt A. Sandman

Psychology Faculty Articles and Research

After delivery, many women experience symptoms of postpartum depression (PPD), and early identification of women at risk is therefore important. The opioid peptide [beta]-endorphin has been implicated in non-puerperal depression but its role in the development of PPD is unknown.

Much Ado About Nothing Much: Protestant Episcopal Church In The Diocese Of Virginia V. Truro Church, Henry L. Chambers Jr.

Law Faculty Publications

Protestant Episcopal Church in the Diocese of Virginia u. Truro Church ("Truro") involves a property dispute. The core issue is who owns or controls property held in trust for an Episcopal congregation after a majority of that congregation votes to disaffiliate from the Episcopal Church of the United States of America ("TEC") and affiliate with a different church. Deciding a church property dispute is inherently difficult because courts are generally "not a constitutionally permissible forum" to resolve ecclesiastical issues. Indeed, the desire to avoid such issues can lead courts to decline to decide particular cases. However, faced with the property …

Reproduction, Distribution, And "Making Available", James Gibson

Law Faculty Publications

When an individual makes a music or movie file available for downloading by others, without the permission of the copyright owner, is that an infringing act? Or does infringement take place only when the file is actually downloaded?

This thorny copyright issue is at the heart of much of the controversy over file-sharing. It’s relatively simple for a copyright owner to prove that a file has been made available for download, but it’s much harder to prove that a download has actually occurred. So if liability attaches to the mere act of “making available,” record labels and movie studios will …

Evaluation Of Liquefaction-Induced Lateral Spreading In The Midwest, Kermit Nathanial Applegate

Masters Theses

"The Central United States is home to several seismically active regions: the Wabash Valley Seismic Zone, the South Central Illinois Seismic Zone, and the New Madrid Seismic Zone. All three of these regions are capable of inducing large ground motion throughout the Mississippi Valley and along the eastern border of Missouri. This has been supported by many paleoseismic studies conducted throughout the region, which have identified numerous instances of liquefaction phenomena. The fluvial deposition process associated with the Mississippi river valley makes it a prime location for possible liquefaction and lateral spreading effects. However, there are few studies pertaining to …

Enhanced Photorefractivity In A Polymeric Composite Photosensitized With Modified Carbon Nanotubes, Naveen Kumar Lingam

Masters Theses

"This work involves the photosensitization of photorefractive polymeric composites through the inclusion of multiwalled and singlewalled carbon nanotubes grafted to poly(N-vinyl carbazole). The photorefractive nature of the holograms gratings was established using two-beam-coupling, yielding two-beam-coupling gain coefficients approaching 80 cm⁻¹. Degenerate-four-wave-mixing experiments exhibited diffraction efficiencies as high as 60% as well as over-modulation voltages as low as ~ 40 V/µm. These notable figures of merit indicate that the grafting of the various carbon nanotubes to the poly(N-vinyl carbazole) polymer resulted in enhanced photorefractive performance. The mechanism responsible for this enhancement in photorefractive performance is investigated using a variety of experimental …

Racial /Ethnic Disparities In Hypertension In United States Residents: A Cross-Sectional Study Of Potential Explanatory Covariates, Franklin I. Opara

Walden Dissertations and Doctoral Studies

Racial/ethnic disparities persist in hypertension (HTN) prevalence in the United States, and African Americans are disproportionately affected. The incidence is more than two-folds in African Americans compared to Caucasians, and mortality is highest among African Americans. Understanding the risk factors in HTN and how these factors vary across racial/ethnic groups is essential to reducing the mortality among African Americans. This study examined the prevalence of HTN among a sample non-institutionalized U.S. residents (N = 30,852), assessed racial/ethnic disparities and determined factors associated with racial/ethnic variance in HTN. A cross-sectional design was used to address these aims, utilizing the National Health …

A Qualitative Study Of Bariatric Patients And Their Social And Emotional Experiences After Surgery, Denise Hall

Walden Dissertations and Doctoral Studies

Previous research has indicated that the majority of individuals who undergo bariatric surgery have histories of psychological disorders. Only a paucity of research has examined the social and emotional effects of bariatric surgery on patients. Using Kelly's personal construct theory as the conceptual framework, this phenomenological study was designed to gain more insight into how this life-altering bariatric surgery transforms patients socially and emotionally. Fifteen participants who had undergone bariatric surgery in the past 10 years were interviewed for the study. The interviews were transcribed and coded. Similar themes found within the interviews were identified as the primary themes of …

The Use Of Handheld Devices For Improved Phonemic Awareness In A Traditional Kindergarten Classroom, Cristy Ann Magagna-Mcbee

Walden Dissertations and Doctoral Studies

Effective teaching strategies that improve the development of phonemic awareness are important to ensure students are fluent readers by third grade. The use of handheld devices to improve phonemic awareness with kindergarten students may be such a strategy, but no research exists that evaluates the use of these devices. This study explored the effectiveness of Bee-Bot handheld devices in kindergarten classrooms to teach phonemic awareness. A 4-month sequential mixed-methods study was conducted in four classrooms: two that used Bee-Bot handheld devices in phonemic awareness lessons and two that never used the devices. The score gain (Fall 2009 to Winter 2010) …

Manual Handling Workload And Musculoskeletal Discomfort Among Warehouse Personnel, Terrance N. Knox

Walden Dissertations and Doctoral Studies

Work-related musculoskeletal disorders (WRMSD), specifically physical and muscular discomfort in the upper arm, lower arm, thigh, lower leg, wrist, shoulders, back, or neck, are among the most frequently reported workplace injuries in the United States. The dearth of knowledge about the types of workloads that may contribute to the development of WRMSD was the impetus of this research. The study aimed to identify antecedents of WRMSD among warehouse workers in order to reduce WRMSDs and increase productivity as expressed in a systems perspective on industrial health. The research questions examined the prevalence of specific WRMSDs, the relationship of high-risk tasks …

The Dissemination Of Teacher Learning: A Study Of The Similarities And Differences Between Public School Levels And Locations, Jacqueline M. Krohn

Walden Dissertations and Doctoral Studies

Teacher learning, whether in-service, continued education, or experience based, is a key component of school reform. Specific research on the use of teacher learning to improve student achievement and instructional practices in and across schools is limited. The research questions addressed in this study were: (a) the degree to which teacher learning is disseminated throughout a school organization to improve student learning and instructional practices, and (b) differences and similarities in the dissemination of teacher learning between schools. Watkins and Marsick's learning organization theory, Senge's system theory, and Dewey's constructivist learning theory were used as the theoretical framework. A variation …

Articles

To compare macronutrient intakes of Swedish children and adolescents to population goals; to identify the major sources of energy, fat, saturated fat and sucrose; and to simulate the effect adherence to current food-based dietary guidelines (FBDG) would have on saturated fat and sucrose intakes. Cross-sectional study. From 24 h recall data, food groups contributing most to energy, fat, saturated fat and sucrose were identified. Based on the prevailing consumption of foods mentioned in the FBDG, we simulated five scenarios: changes in milk and yoghurt; cheese; energy-dense, nutrient-dilute foods; soft drinks; and burger and sausage consumption. Stockholm and Örebro (Sweden) in …

Nearest Neighbor Search With Strong Location Privacy, Stavros Papadopoulos, Spiridon Bakiras, Dimitris Papadias

Publications and Research

The tremendous growth of the Internet has significantly reduced the cost of obtaining and sharing information about individuals, raising many concerns about user privacy. Spatial queries pose an additional threat to privacy because the location of a query may be sufficient to reveal sensitive information about the querier. In this paper we focus on k nearest neighbor (kNN) queries and define the notion of strong location privacy, which renders a query indistinguishable from any location in the data space. We argue that previous work fails to support this property for arbitrary kNN search. Towards this end, we introduce methods that …

Pluralism, Secularism And The European Court Of Human Rights, Zachary R. Calo

Scholarly Works

Beginning with its seminal 1993 decision in Kokkinakis v. Greece, the European Court of Human Rights has defined religious pluralism as an essential good of the liberal democratic society. Yet, in subsequent decisions traversing a range of legal issues [e.g. Sahin, Dahlab, Bayatyan, and Lautsi], the Court has rendered decisions facially at odds with the goal of advancing religious pluralism. This paper is concerned with assessing the discontinuity between the Court’s high embrace of normative religious pluralism and its failure to consistently realize this ideal in practice.The paper argues that the Court has failed to consistently render decisions in accord …
