The Reproducibility And Validity Of Using The Dmax Method To Predict Physical Working Capacity At Fatigue Threshold, Joshua Riffe

Electronic Theses and Dissertations

Although the original (ORG) physical working capacity at fatigue threshold (PWCFT) assessment has demonstrated strong reliability and sensitivity to training and/or nutritional interventions, limitations may exist regarding the method of PWCFT estimation. However, a relatively new mathematical method, called Dmax, has been shown to be objective and reliable when estimating metabolic and neuromuscular fatigue thresholds. To date, however, no study has examined whether the Dmax method for estimating the work rate at PWCFT is similar to the ORG method. PURPOSE: The purpose of this study is to evaluate the reliability and validity of the Dmax-EMG method for estimating and tracking …

Dynamical Formation Of Protoplanetesimals, Akbar Whizin

Electronic Theses and Dissertations

The seeds of planetesimals that formed in the gaseous protoplanetary disk (PPD) have many barriers to overcome in their growth from millimeter to meter-sized and larger bodies. Centimeter-sized aggregates are weakly bound and self-gravity is almost non-existent so surface forces play a critical role in holding small loosely-bound rubble-piles together. Their orbital motions and effects form disk processes impart relative velocities leading to collisions so understanding the macroscopic disk environment is also necessary. To this end we analyze the dynamics of particles in Saturn's F ring as an analogue to understanding the orbital evolution of proto-planetesimals embedded in a PPD. …

Trade-Offs Between Three Forest Ecosystem Services Across The State Of New Hampshire, Usa: Timber, Carbon, And Albedo, David A. Lutz, Elizabeth A. Burakowski, Mackenzie B. Murphy, Mark E. Borsuk

Dartmouth Scholarship

Forests are more frequently being managed to store and sequester carbon for the purposes of climate change mitigation. Generally, this practice involves long-term conservation of intact mature forests and/or reductions in the frequency and intensity of timber harvests. However, incorporating the influence of forest surface albedo often suggests that long rotation lengths may not always be optimal in mitigating climate change in forests characterized by frequent snowfall. To address this, we investigated trade-offs between three ecosystem services: carbon storage, albedo-related radiative forcing, and timber provisioning. We calculated optimal rotation length at 498 diverse Forest Inventory and Analysis forest sites in …

Impaled On Morton's Fork: Kosovo, Crimea, And The Sui Generis Circumstance, Christopher R. Rossi

Emory International Law Review

Since NATO's intervention in Kosovo, the invocation of sui generis, or unique circumstances, has been used to justify circumventing international law on the use of force and state secession. In this Article, Professor Christopher Rossi addresses lessons learned from NATO's 1999 intervention in Kosovo and adapts those teachings to Russia's 2014 annexation of Crimea. Professor Rossi exposes internal tensions within the United Nations Charter system that threaten to further weaken the system and expose it to dangerous manipulations. These weaknesses help explain why two of the most significant doctrinal developments to emerge from the midst of Kosovo'the Responsibility to Protect …

Novel Machine Learning Methods For Modeling Time-To-Event Data, Bhanukiran Vinzamuri

Wayne State University Dissertations

Predicting time-to-event from longitudinal data where different events occur at different time points is an extremely important problem in several domains such as healthcare, economics, social networks and seismology, to name a few. A unique challenge in this problem involves building predictive models from right censored data (also called as survival data). This is a phenomenon where instances whose event of interest are not yet observed within a given observation time window and are considered to be right censored. Effective models for predicting time-to-event labels from such right censored data with good accuracy can have a significant impact in these …

Social Media Adoption Among University Instructors In Saudi Arabia, Khalid Abdulaziz Alasfor

Wayne State University Dissertations

There is an orientation from the government of Saudi Arabia toward social media in general. The government of Saudi Arabia considers the significance of social media in educating the Saudi community. The Saudi Ministry of Education founded the National Center for E- Learning and Distance Learning (NCeL) because it considered the importance of e-learning and distance learning for higher education (he.moe.gov.sa). NCeL supports and rewards university instructors to integrate social media in the learning process (award.elc.edu.sa). Several studies proved the significance of social media with Saudi higher education students (Alkhalifa, 2008; Salem and Alghamdi, 2011; Almadhouni, 2011). Moreover, Saudi students …

Objective Statistics For The Measurement Of Agreement, Elizabeth Perkin Moen

Wayne State University Dissertations

The prevailing method for biomedical device interchangeability is a scatterplot of means and differences bounded by levels of agreement (Bland-Altman Plot) which results in subjective judgments made in the discernment of differences in data distribution and fit. The purpose of this study was to test four statistics - the Kolmogorov-Smirnov test, and three fit indices (NFI, GFI, & CFI) in order to identify a more objective statistic for device interchangeability. The Kolmogorov-Smirnov test proved incompatible with the data structure. The Normed Fit Index (NFI) proved most sensitive to correlation shifts where the Goodness of Fit Index (GFI) and Comparative Fit …

Student, Teacher, School, And District Determinants Of Elementary School Accountability Classification In The Detroit Metropolitan Region, Embekka Nakia Thompson

Wayne State University Dissertations

Legislators have implemented an accountability system in an effort to increase school quality for all students. Policymakers assume that rewards and sanctions, based on results from high-stakes testing, can improve student achievement. The accountability system does not consider environmental factors that impact student outcomes. This study examines student, teacher, school and district determinants and their impact on student achievement, school designation, and school ranking. Data was collected from 333 elementary (K-5) schools in 56 public school districts and 18 charter schools in three counties: Macomb, Oakland, and Wayne. Two research questions were developed for this study.The first research question examined …

Effect Of Fiber Orientation On Dynamic Compressive Properties Of An Ultra-High Performance Concrete, Andrew B. Groeneveld

Dissertations, Master's Theses and Master's Reports

Casting structural elements with ultra-high performance concrete (UHPC) tends to create preferential fiber alignment, which affects the strength and must be accounted for in design. Fiber orientation effects in tension have been studied extensively, but less work has been performed for compression. This work characterizes the fiber orientation occurring in a typical UHPC beam and how that orientation affects compressive behavior at high strain rates. Specimens (36 total) were cored from the beam and their fiber orientations were non-destructively evaluated using x-ray computed tomography (CT). Fibers showed flow-induced alignment along the length of the beam, with orientation angles in the …

A “Rule-Of-Five” Framework For Models And Modeling To Unify Mathematicians And Biologists And Improve Student Learning, Kam D. Dahlquist

Biology Faculty Works

Despite widespread calls for the incorporation of mathematical modeling into the undergraduate biology curriculum, there is lack of a common understanding around the definition of modeling, which inhibits progress. In this paper, we extend the “Rule-of-Four,” initially used in calculus reform efforts, to a “Rule-of-Five” framework for models and modeling that is inclusive of varying disciplinary definitions of each. This unifying framework allows us to both build on strengths that each discipline and its students bring, but also identify gaps in modeling activities practiced by each discipline. We also discuss benefits to student learning and interdisciplinary collaboration.

Monte Carlo Algorithm To Study Performance Parameters Of Shuttle Systems, Wolfgang Trummer, Dirk Jodin

14th IMHRC Proceedings (Karlsruhe, Germany – 2016)

Shuttle systems provide alternative solutions in storage technology. Ma-terial flow analyses of these systems are extensive due to complex interac-tion of several shuttles and lift elements. Besides classic cycle time calcu-lation, it also requires advanced analyzing methods. At the Institute of Logistics Engineering (ITL), Graz University of Technology, an innovative, software-based approach has been developed to investigate the performance of shuttle systems. This approach is based on the Monte Carlo method. The software tool takes into account a variety of different systems and operating parameters to reflect operative behavior of shuttle systems.

Publications and Research

The Bou Dahar Pb–Zn–Ba (±Sr) is hosted in the Lower and Middle Liassic carbonate platform in the oriental High Atlas of Morocco. The paragenetic sequence includes quartz–pyrite–melnicovite–sphalerite–galena– calcite–barite ± fluorite– ± celestite. Fluid-inclusion studies were conducted on sphalerite (early mineralizing stage) and barite, and celestite (late mineralizing stage). These studies reveal two end-member fluids, a hot (~143 °C) and saline fluid (~23 wt.% NaCl eq.) and a cooler (b50 °C) and diluted fluid (~5 wt.% NaCl eq.). Based on fluid-inclusion and C–O–S isotope studies, a conclusion is reached that the Bou Dahar ore deposits were formed by the mixing of …

Lifemusic: Reflection Of Life Memories By Data Sonification, Ridwan Ahmed Khan, Ram K. Avvari, Katherine Wiykovics, Pooja Ranay, Myounghoon Jeon

Department of Psychology and Human Factors Publications

Memorable life events are important to form the present selfimage. Looking back on these memories provides an opportunity to ruminate meaning of life and envision future. Integrating the life-log concept and auditory graphs, we have implemented a mobile application, "LifeMusic", which helps people reflect their memories by listening to their life event sonifcation that is synchronous to these memories. Reflecting the life events through LifeMusic can relieve users of the present and have them journey to the past moments and thus, they can keep balance of emotions in the present life. In the current paper, we describe the implementation and …

Population Health Science: A Core Element Of Health Science Education In Sub-Saharan Africa, Robert A. Hiatt, Natalie J. Engmann, Mushtaq Ahmed, Yasmin Amarsi, William Macharia, Sarah B. Macfarlane, Anthony Ngugi, F. Rabbani, Gijs Walraven, Robert Armstrong

Paediatrics and Child Health, East Africa

Sub-Saharan Africa suffers an inordinate burden of disease and does not have the numbers of suitably trained health care workers to address this challenge. New concepts in health sciences education are needed to offer alternatives to current training approaches. A perspective of integrated training in population health for undergraduate medical and nursing education is advanced, rather than continuing to take separate approaches for clinical and public health education. Population health science educates students in the social and environmental origins of disease, thus complementing disease-specific training and providing opportunities for learners to take the perspective of the community as a critical …

Cognition And Reason: Rethinking Kelsen In The Context Of Contract And Business Law, Jeffrey M. Lipshaw

Suffolk University Law School Faculty Works

This is a reconsideration of Hans Kelsen’s pure theory of law from the standpoint of a long-time business lawyer, contract theoretician, and Kant-influenced epistemologist. The essay: (a) reconsiders the pure theory in the context of contract and business law (i) in light of how legal reasoning operates (something the pure theory accurately characterizes) in contract and business law (as, for example, in the classic consideration/promissory estoppel case, Allegheny College), and (ii) with a more faithful or more satisfying account than Kelsen provided of the kind of knowledge we obtain if we are going to think of contract and business …

Nursing Faculty Reports Of Their Intention To Design Instruction To Support Student Learning In Community College Classrooms, Ann-Marie Evans

Nursing Faculty Publications

The purpose of this exploratory case study was to describe community college nursing faculty members' reports of their intention to design instruction to support learning for a broad range of students in their classrooms. Specifically, Ajzen's (1985) Theory of Planned Behavior (TPB) was the conceptual framework used to analyze nursing faculty members' reports of their attitudes, normative beliefs, and control beliefs related to the three Universal Design for Learning (CAST, 2011) principles. Ajzen theorized that individuals base their behaviors on intention and intentions are based on the individuals' attitudes toward the behavior, their perceptions of how others wanted them to …

Geochemistry Of Upper Cretaceous Sediments Of Bozeş Formation (Apuseni Mts., Romania) – Provenance Implications, Luminiţa Zaharia, Romona Bălc, Cosmin C. Stremţan, Adriana Socaciu

School of Geosciences Faculty and Staff Publications

A whole-rock geochemical study was carried out on sandstones from the Upper Cretaceous Bozeş Formation in the southeastern part of the Apuseni Mountains (Romania) in order to constrain their provenance and depositional setting. The geochemical results were compared and integrated with previously reported provenance indicators, such as framework composition and heavy mineral assemblages. The chemical composition is similar for all samples investigated, with limited ranges for both major oxides and trace elements. The sandstones are potassic (Na₂O/K₂O < 1) and can be classified mainly as arenites with a few greywackes. Their immature to relatively mature character is revealed by the SiO₂/Al₂O₃ ratios, ranging between 3.90 and 11.25, as well as their high Sr/Rb ratios. The …
