Defining The Hemodynamic Response Of Hypertensive And Normotensive Subjects Through Serial Timed Blood Pressure Readings In The Clinic, Hunaina Shahab, Hamza Sohail Khan, Aysha Almas, Sohail Abrar Khan, Azmina Artani, Aamir Hameed

Section of Cardiology

Background: Every third patient in the clinic is misdiagnosed due to white-coat phenomenon, necessitating needless and costly treatment. We aimed to study the hemodynamic response of the physician's visit on hypertensive and normotensive patients by investigating the trend of blood pressure (BP) before, during and 15 min after the physician-patient encounter.
Methods: A descriptive, cross-sectional study was conducted over a period of 8 months in the cardiology clinics at the Aga Khan University Hospital, Karachi. Both hypertensive and normotensive patients, aged ≥18 years, were recruited. Pregnant females or those with a history of volume loss were excluded. BP readings were …

The Applications Of Grid Cells In Computer Vision, Keaton Kraiger

Maseeh Summer Undergraduate Research Experience

In this study we present a novel method for position and scale invariant object representation based on a biologically-inspired framework. Grid cells are neurons in the entorhinal cortex whose multiple firing locations form a periodic triangular array, tiling the surface of an animal’s environment. We propose a model for simple object representation that maintains position and scale invariance, in which grid maps capture the fundamental structure and features of an object. The model provides a mechanism for identifying feature locations in a Cartesian plane and vectors between object features encoded by grid cells. It is shown that key object features …

Controlled Ecological Evaluation Of An Implemented Exercise-Training Programme To Prevent Lower Limb Injuries In Sport: Population-Level Trends In Hospital-Treated Injuries, Caroline F. Finch, Shannon E. Gray, Muhammad Akram, Alex Donaldson, David G. Lloyd, Jill L. Cook

Research outputs 2014 to 2021

OBJECTIVE: Exercise-training programmes have reduced lower limb injuries in trials, but their population-level effectiveness has not been reported in implementation trials. This study aimed to demonstrate that routinely collected hospital data can be used to evaluate population-level programme effectiveness.

METHOD: A controlled ecological design was used to evaluate the effect of FootyFirst, an exercise-training programme, on the number of hospital-treated lower limb injuries sustained by males aged 16-50 years while participating in community-level Australian Football. FootyFirst was implemented with 'support' (FootyFirst+S) or 'without support' (FootyFirst+NS) in different geographic regions of Victoria, Australia: 22 clubs in region 1: FootyFirst+S in 2012/2013; …

A Program Evaluation Of The Parent Academy For One School District, Kathleen Gordon

Dissertations

ABSTRACT

This program evaluation project addresses issues relating to low-parent attendance at one district’s parent academy. The process I used to gather information from the parents, administrators, board members, and business partners included individual surveys and interviews. The results indicated the biggest problems for mediocre parent engagement centered on transportation and the lack of parent involvement in the planning process. Improving the strategic planning process of the parent academy was the dominant need I identified based on my Change Leadership Plan. Included is a policy amendment regarding parent involvement in matters related to student achievement.

An Evaluation Of The In-School Suspension Program At One High School, Monique Griffin-Gay

Dissertations

In this program evaluation, I examined the effectiveness of in school suspension (ISS) program at one high school. The literature reviewed argues although ISS is a necessity in the current climate of education, ineffective ISS programs can interrupt academic progress. Often used in isolation and as a holding area for code of conduct violations, ISS can yield results such as increased recidivism, increased hostility and decreased academic progress. The methods used within this study included surveys and interviews from key stakeholders. The results revealed some things were working well, and some things were not. In conclusion, Eminence High should incorporate …

Attendance Matters! A Policy Advocacy Document, Robert G. Hubbird

Dissertations

This three-part dissertation concentrates on student attendance. It is clear that we have a student attendance problem in our nation, particularly in urban school districts. There have been other studies, discussions, and debates on how to improve student attendance, but identifying a single policy, program, incentive, and/or intervention to positively impact absenteeism is difficult. Student absenteeism has and will continue to be a national problem. Many factors play a role in student attendance, to a certain degree, some are controllable and others are extremely difficult to affect.

This Part III of the dissertation is a Policy Advocacy for absenteeism at …

Assessment And Verification Of Commercially Available Pressure Cookers For Laboratory Sterilization, Vaille Alena Swenson

Masters Theses & Doctoral Dissertations

Microbiology laboratory experiments require careful maintenance of sterile reagents and tools as well as the sterilization of waste prior to disposal. However, steam autoclaves typically used for this purpose may not be readily accessible to everyone in the scientific community, such as K-12 teachers, researchers in the field, or students in under-funded laboratories. This work examines the use of commercial electric pressure cookers as an alternative method for the sterilization of media, instruments, and waste. Four commonly available brands of pressure cooker were tested for their ability to sterilize microbiological media, a variety of metal instruments, and high-titer microbial cultures. …

Investigating The Kinetics Of Clay-Catalyzed Conversion Of Anthracene To Prebiotically Relevant 9,10-Anthroquinone, Hope Juntunen

Masters Theses & Doctoral Dissertations

The presence polycyclic aromatic hydrocarbons (PAHs) on the primordial Earth can be attributed to carbonaceous meteorites bombarding planetary surfaces. Subsequently, the PAHs reacted with catalytic clay mineral surfaces to produce quinones that functioned as electron transporters in emergent biological systems. To address this hypothesis, we assessed the kinetics of anthracene (ANTH) conversion to 9,10-anthraquinone (ANTHQ) in the presence of montmorillonite and kaolinite clay (MONT and KAO, respectively) over the temperature range 25 to 250 oC. Apparent rates of conversion were concentration independent and displayed a sigmoidal relationship with temperature, and conversion efficiencies ranged from 0.027 to 0.066%. Conversion was not …

Housing And Mobility Toolkit For San Mateo County, Serena Alexander, Joseph Kott, Bruce Appleyard, Mark Garrett, Shannon Mcdonald, Maaza Mekuria, Udeme J. Ndon, Anurag Pande, Eric Peterson

Mineta Transportation Institute

Since the end of the Great Recession, San Mateo County has attracted new workers at a record rate without building anywhere near enough housing. This jobs-housing imbalance drives the cost of housing up and forces many moderate and lower-income employees and their families out of the County. A lack of access to quality affordable housing in the County and the entire Bay Area along with limited transportation options means that an increased number of employees drive in and out of the County every workday. The resultant congestion, gridlock, and long commutes along with other negative environmental, social, and economic impacts …

The Next Frontier For Men's Contraceptive Choice: College Men's Willingness To Pursue Male Hormonal Contraception, Laurel M. Peterson, Meriel A. T. Campbell, Zoë E. Laky

Psychology Faculty Research and Scholarship

Unplanned pregnancy is a concern for emerging adult men, but their contraceptive options are limited. With male hormonal contraception clinical trials in progress, it is important to investigate men’s attitudes toward alternative contraception. Many social factors, such as masculine norms, may hinder their interest. This study used the prototype–willingness model to investigate college men’s willingness to pursue hormonal contraception. Male college students (N = 160; Mage = 19.37, SD = 1.33; 61.9% White) read a description of male contraception clinical trials and filled out a questionnaire assessing prototype–willingness and masculinity constructs. Multinomial logistic regression revealed that men perceiving greater …

Analysis Of Operational Parameters, Reactor Kinetics, And Floc Characterization For The Removal Of Estrogens Via Electrocoagulation, Emily K. Maher, Kassidy N. O'Malley, Joe Heffron, Jingwan Huo, Brooke K. Mayer, Yin Wang, Patrick J. Mcnamara

Civil and Environmental Engineering Faculty Research and Publications

Estrogenic compounds can cause human and ecological health issues and have been detected in surface and drinking water. In this research a reactor analysis determined the impact of operational parameters, the best fit kinetic model for the removal of estrone (E1), 17β-estradiol (E2), estriol (E3), and 17α-ethynylestradiol (EE2) using a bench-top iron electrocoagulation reactor, and characterized the floc generated in-situ. The parameters investigated were current density, conductivity, stir rate, and polarity reversal. Estrogen removal correlated well with an increase in current density, while conductivity did not impact removal but did reduce potentials. High stir rates and frequent polarity reversal …

The Role Of Elites In The Diffusion Of Social Norms Of Humanitarianism, Khadijeh Salimi, Erika Frydenlund, Jose J. Padilla, Hanne Haaland, Hege Wallevik

Political Science & Geography Faculty Publications

Certain social norms evolve without punishment as conventions that do not adversely affect society. In this paper, we depart from the notion that humanitarianism is one such social norm, where peer pressure may be the only type of punishment that encourages individuals to conform. Using an agent-based modeling approach, we examine the role that networked elites have in diffusing a non-punishment-enforced norm through an artificial society. The model considers norm advocates who promote a norm of humanitarianism, elites who have wide networks to spread the new norm, and general individuals who evaluate the norm pushed from elites and adopted by …

Fool Me Once, Shame On You; Fool Me Twice, Shame On You Again: How Disparate Treatment Doctrine Perpetuates Racial Hierarchy, David Simson

Articles & Chapters

Title VII race discrimination doctrine is excessively hostile to workers of color, and many observers agree that it needs to be fixed. Yet comparatively few analyses of the doctrine weave together doctrinal and theoretical insights with systematic empirical findings from social science. This Article looks to Social Dominance Theory—a social psychology theory with a robust body of supporting empirical research—to take on this task and connect judicial interpretation of Title VII to the human tendency to create and maintain group-based hierarchies. In doing so, the Article questions the common view that Title VII race discrimination doctrine is symmetrical, protecting all …

Perturbative Generalization Of Nonparaxial Ultrashort Tightly-Focused Elegant Laguerre–Gaussian Beams, Andrew M. Vikartofsky

Department of Physics and Astronomy: Dissertations, Theses, and Student Research

An analytical method for calculating the electromagnetic fields of a nonparaxial elegant Laguerre-Gaussian (eLG) vortex beam is presented for arbitrary pulse duration, spot size, and LG mode. This perturbative approach provides a numerically tractable model for the calculation of arbitrarily high radial and azimuthal LG modes in the nonparaxial regime, without requiring integral representations of the fields. A key feature of this perturbative model is its use of a Poisson-like frequency spectrum, which allows for the proper description of pulses of arbitrarily short duration. The time-domain representation of this model is presented as a non-recursive closed-form expression to any order …

The Ecological Niche Of Echinococcus Multilocularis In North America: Understanding Biotic And Abiotic Determinants Of Parasite Distribution With New Records In New Mexico And Maryland, United States, Sebastian Botero-Cañola, Altangerel Tsogtsaikhan Dursahinhan, Sara E. Rácz, Parker V. Lowe, John E. Ubelaker, Scott Lyell Gardner

Scott L. Gardner Publications

English abstract: Understanding the factors shaping the niche of parasites and its expression over geographical space and through time continues to be a modern scientific challenge with the results of research in this area directly influencing both theoretical and applied biology. This is especially important for proactive management of zoonotic parasites such as Echinococcus multilocularis, the etiologic agent of alveolar echinococcosis. Echinococcus multilocularis has a Holarctic distribution; with its geographic range and prevalence increasing recently in areas of the western Palearctic, while its distribution dynamics are poorly understood in the Nearctic. In this paper, we use an ecological niche …
