Effects Of Knee Sleeves On Knee Mechanics During Squats At Variable Depths, Alexandria A. Trypuc
Human Movement Studies & Special Education Theses & Dissertations
The squat is a functional, compound and multi-joint exercise that targets several muscles of the lower body and is widely used in both athletics and many exercise programs. This exercise has been the subject of many studies, comparing different squat variations and examining how external gear, such as squat suits and knee wraps impact the exercise. The aim of this study was to assess the effects of wearing neoprene knee sleeves on lower extremity kinematics, kinetics, and muscle activations during weighted back squats. Fifteen resistance trained men and women, aged 28±5 years, from the local fitness community and university campus …
Countervisuality As Policy Feedback: A Critical Policy Study On The Symbolic Role Of Visual Culture In Contemporary Antiracist Resistance, Lindsay N. Plott-Buckner
Countervisuality As Policy Feedback: A Critical Policy Study On The Symbolic Role Of Visual Culture In Contemporary Antiracist Resistance, Lindsay N. Plott-Buckner
School of Public Service Theses & Dissertations
This critical interpretive study explores the relationship between public policy and visual culture. Drawing from five areas of research literature on (1) policy feedback theory, (2) the spectacle, (3) art and visual culture, (4) Black feminist theory, (5) and critical philosophies of resistance, images of contemporary antiracist activism are conceptualized as a form of policy feedback. Photographs of Ieshia Evans, Bree Newsome, and a self-portrait by Nona Faustine are reverse searched through Google Images. Utilizing constructivist grounded theory, a collection of publicly available news articles, blogs, and social media content are analyzed to better understand how mass publics engage with …

A Continuum Of Care: School Librarian Interventions For New Teacher Resilience, Rita Reinsel Soulen
Teaching & Learning Theses & Dissertations
School librarians occupy a unique position to offer supports for first year teachers to build resilience, reduce burnout, and ensure retention. The researcher used the psychology theory of resilience to develop the Continuum of Care model which initiates in mentoring and moves toward a collaborative partnership. Fifteen school librarians in one urban district recruited 26 new teachers in their schools to form the treatment group. All new teachers in the district were surveyed to establish their initial level of resilience and collect demographics. A comparison group of 26 new teachers were matched by scores on a resilience scale at the …
Three Essays On Ceo Risk Preferences, And Ability, Corporate Hedging Decisions, And Investor Sentiment, Sonik Mandal
Three Essays On Ceo Risk Preferences, And Ability, Corporate Hedging Decisions, And Investor Sentiment, Sonik Mandal
Finance Theses & Dissertations
The derivative hedging research has looked at why firms and how firms hedge and if it increases value for their shareholders. In this dissertation we investigate the relation between CEO risk preferences and ability and whether if affects their hedging decisions and firm value.
In our first essay, we challenge the theory and previous empirical evidence that showed CEO risk preferences affects hedging. Using a sample of Fortune 500 firms and 5 years of panel data, and using inside debt (i.e., CEO pension and deferred compensation) and the CEO Vega and CEO Delta, as proxies of CEO risk preferences, we …

Pragmatism And Pluralism: A Moral Foundation For Stakeholder Theory In The 21st Century, Paul C. Godfrey, Ben William Lewis
Pragmatism And Pluralism: A Moral Foundation For Stakeholder Theory In The 21st Century, Paul C. Godfrey, Ben William Lewis
Faculty Publications
Donaldson and Preston (1995) defined the three pillars of stakeholder as descriptive, instrumental, and normative. Because of their close alignment between the instrumental and normative pillars and the moral philosophies of utilitarianism and deontology, the latter became the default moral foundations of stakeholder theory. In this chapter, we argue that the moral foundation of the descriptive pillar, pragmatism, provides a moral foundation for twenty-first century stakeholder theory. As we show, pragmatism and its close cousin pluralism fits a stakeholder theory concerned with the descriptive questions that characterize current work in stakeholder theory. Pragmatism and pluralism both see eudemonia, or human …

M. Zaidi, Fyezah Jehan
Department of Paediatrics and Child Health
Background: Benefits of pneumococcal conjugate vaccine programs have been linked to the vaccine’s ability to disrupt nasopharyngeal carriage and transmission. The 10-valent pneumococcal vaccine (PCV10) was included in the Expanded Program on Immunization (EPI) in Sindh, Pakistan in February 2013. This study was carried out immediately before PCV10 introduction to establish baseline pneumococcal carriage and prevalent serotypes in young children and to determine if carriage differed in urban and rural communities.
Methods: Nasopharyngeal specimens were collected from a random sample of children 3-11 and 12-59 months of age in an urban community (Karachi) and children 3-11 months of age in …

Department of Neurology Faculty Papers
BACKGROUND: Outcomes after stroke in those with diabetes are not well characterized, especially by sex and age. We sought to calculate the sex- and age-specific risk of cardiovascular outcomes after ischemic stroke among those with diabetes.
METHODS: Using population-based demographic and administrative health-care databases in Ontario, Canada, all patients with diabetes hospitalized with index ischemic stroke between April 1, 2002, and March 31, 2012, were followed for death, stroke, and myocardial infarction (MI). The Kaplan-Meier survival analysis and Fine-Gray competing risk models estimated hazards of outcomes by sex and age, unadjusted and adjusted for demographics and vascular risk factors.

Advances In The Diagnosis, Immunopathogenesis And Therapies Of Igm-Anti-Mag Antibody-Mediated Neuropathies., Marinos Dalakas
Department of Neurology Faculty Papers
Polyneuropathy with immunoglobulin M (IgM) monoclonal gammopathy is the most common paraproteinemic neuropathy, comprising a clinicopathologically and immunologically distinct entity. The clinical spectrum spans from distal paresthesias and mild gait imbalance to more severe sensory ataxia, with falls and a varying degree of distal sensorimotor deficits. In approximately 75% of patients, the monoclonal IgM immunoreacts with myelin-associated glycoprotein (MAG) and sulfoglucuronyl glycosphingolipid (SGPG), or other peripheral nerve glycolipids that serve as antigens. These antibodies are considered pathogenic because IgM and complement are deposited on the myelin sheath, splitting the myelin lamellae, while adoptive transfer of patients' IgM into susceptible host …
Ganesh Sitaraman’S Idealized American History, David B. Lyons
Ganesh Sitaraman’S Idealized American History, David B. Lyons
Faculty Scholarship
A popular theme among patriots is to celebrate America’s special virtues, which distinguish it radically from European models. Ganesh Sitaraman tells us that political constitutions have generally been designed to prevent socially destabilizing class warfare between the rich, who seek greater domination, and the poor, who would like to redistribute the former’s wealth. America’s Constitution is distinctive because it was consciously designed for a society in which the middle class is large enough to preserve social stability. That is why Sitaraman calls it a “middle-class constitution.”
Corporate Rights As Subplot, Larry Yackle
Corporate Rights As Subplot, Larry Yackle
Faculty Scholarship
Adam Winkler makes an important contribution to the great body of academic work on corporations in American life. He concentrates on a small corner of the larger topic. He traces only the development of corporate “rights,” and he describes, but does not critique, what he uncovers. There is much to learn from this fine book. I want to applaud Winkler’s primary revelation—namely, that corporate rights are a creation of the courts, especially the Supreme Court.1 Then I want to flag what Winkler (I think) would readily acknowledge: corporate rights are not the whole of the corporate story.

Turkish Journal of Earth Sciences
The obliteration of the Neo-Tethyan Ocean and collision of the microplates along the northern part of Turkey led to the development of the İzmir-Ankara-Erzincan suture zone (IAESZ). After the collision of Pontides with the Central-Anatolian Crystalline Complex (CACC) in the Paleocene, a new phase of extension and volcanism concomitantly developed along the northern (Almus; Pontides) and southern (Yıldızeli; CACC) sides and along the IAESZ during the Middle Eocene time interval. The first products of the Middle Eocene volcanism in these areas are represented by calc-alkaline to alkaline (basic-intermediate) volcanic and volcanoclastic units together with late-stage trachytic dikes, plugs, and stocks. …
Influence Of Leachate On The Oligocene-Miocene Clays Of The İstanbul Area, Turkey, Sadik Öztoprak, Davut Laçi̇n
Influence Of Leachate On The Oligocene-Miocene Clays Of The İstanbul Area, Turkey, Sadik Öztoprak, Davut Laçi̇n
Turkish Journal of Earth Sciences
Oligo-Miocene clay outcrops on the European side (west and northwest part) of İstanbul were analysed. Formerly, a landfill and sanitary landfill were built on the clay. Mineral liners of the current and extending parts of the İstanbul landfill consist of these clays, since they include a considerable amount of smectite, illite, and kaolinite. With this feature, these clays are also an important candidate for the buffer material of repositories for nuclear wastes of newly planned nuclear power plants. In this context, one Miocene and two Oligocene clay samples were subjected to leachate under low stress using an odometer device during …

Reconstructing The Sedimentary Evolution Of The Miocene Aksu Basin Based On Fan Delta Development (Eastern Mediterranean-Turkey), Serkan Üner, Erman Özsayin, Ramazan Kadi̇r Di̇ri̇k, Tahsi̇n Atti̇la Çi̇ner, Mustafa Karabiyikoğlu
Turkish Journal of Earth Sciences
The Aksu Basin in southern Turkey is dominantly represented by an alluvial fan and five fan deltas (FDs) developed along the tectonically controlled margins of the basin during the Miocene. Four alternating compressional and tensional tectonic phases have influenced the basin since its formation. Strong tectonic movements caused high sedimentation rates and progradation of large debris-flow and mass-flow dominated FDs. Here we describe two FDs (the Karadağ and Kargı FDs) in detail. The Karadağ FD began to develop under the control of a compressional regime and continued the evolution under a tensional regime. The same tensional regime caused the separation …

Heavy Minerals And Exotic Pebbles From The Eocene Flysch Deposits Of The Magura Nappe (Outer Western Carpathians, Eastern Slovakia): Their Composition And Implications On The Provenance, Katarína Bónová, Ján Bóna, Martin Kovácik, Tomás Mikus
Turkish Journal of Earth Sciences
The study aims to reconstruct the crystalline parent rock assemblages of the Eocene Strihovce Formation (Krynica Unit) and Mrazovce Member (Raca Unit) deposits, based on the heavy mineral suites, their corrosive features, geochemistry of garnet and tourmaline, zircon cathodoluminescence (CL) images, and exotic pebble composition. Both units are an integral part of the Magura Nappe belonging to the Flysch Belt (Outer Western Carpathians). Corrosion signs observable on heavy minerals point to different burial conditions and/or diverse sources. The compositions of the detrital garnets and tourmalines as well as the CL study of zircons indicate their origin in gneisses, mica schists, …

Triassic-Jurassic Arc Magmatism In The Pontides As Revealed By The U-Pb Detrital Zircon Ages In The Jurassic Sandstones Of Northeastern Turkey, Remzi̇ye Akdoğan, Aral I. Okay, István Dunkl
Turkish Journal of Earth Sciences
The Eastern Pontides were located at the southern active margin of Laurasia during Mesozoic time. Jurassic volcaniclastic sediments and volcanic rocks of the Pontides represent products of the arc magmatism above a north-dipping subduction zone. Despite the wide distribution of the Jurassic volcaniclastic/volcanic succession, the precise age of the Jurassic volcaniclastic sequence and that of the synsedimentary magmatism are poorly constrained. Here we present U-Pb detrital zircon ages from two Jurassic sandstones belonging to the Şenköy Formation of the Eastern Pontides. One sample is taken from the base of the Şenköy Formation unconformably overlying the late Carboniferous Gümüşhane granite. The …

Morphotectonic Analysis Of The East Anatolian Fault, Turkey, Abdelrahman Khalifa, Zi̇yadi̇n Çakir, Lewis Owen, Şi̇nasi̇ Kaya
Turkish Journal of Earth Sciences
The East Anatolian Fault (EAF) is a morphologically distinct and seismically active left-lateral strike-slip fault that extends for ~400 km and forms the Arabian/Anatolian plate boundary in southeastern Turkey. The EAF together with its conjugate fault, the North Anatolian Fault, help accommodate the westward escape of the Anatolian plate from the Arabian/Eurasian collision zone. Morphotectonic features along the EAF provide insights into the nature of landscape development and aid in understanding variations in tectonic activity and fault evolution. Several geomorphic indices, namely stream length-gradient index, mountain-front sinuosity, valley width to valley height ratio, basin asymmetry factor, and drainage density, and …

Cathodoluminescence, Fluid Inclusions, And Trace Element Data For The Syntaxial Quartz Cementation In The Sandstones Of The Ora Formation, Northern Iraq, Muhamed F. Omer, Henrik Friis
Turkish Journal of Earth Sciences
Quartz cements of the quartz arenitic sandstones from the Chalky Nasara and Ora sections of the (Devonian-Carboniferous) Ora Formation in northern Iraq have been studied. A combination of hot cathodoluminescence, LA-ICP-MS, and fluid inclusion microthermometry revealed three syntaxial quartz cement generations (Q1, Q2, and Q3). The early Q1 cementation has gray to slightly brown luminescences, postdated compaction, and reduced intergranular porosity associated with illite formed during eogenesis. Q2 is characterized by dark brown luminescence overgrowths and is more voluminous in the thinly bedded sandstones than in the thickly bedded sandstones filling most of the remaining pore space during mesogenesis. Q3 …

Origin Of The Pleonaste-Bearing Mafic-Ultramafic Rocks From The Armutlu Peninsula, Nw Turkey, Mutlu Özkan, Ömer Faruk Çeli̇k
Turkish Journal of Earth Sciences
Al-rich spinels were rarely reported compared to Cr-spinels, which were mostly observed in ophiolitic rocks. Pleonaste [(Mg, Fe2+)Al2O4], which is an Al-rich spinel, was observed in the ophiolitic mafic-ultramafic rocks tectonically located in the Early Cretaceous accretionary complex, at the eastern part of the Armutlu peninsula, NW Turkey. The ophiolitic mafic-ultramafic rocks have cumulate character, and most of them are represented by peridotite and pyroxenite. Pleonaste was observed in pyroxenites and gabbros of the ophiolitic rocks. Pyroxenites consist mainly of clinopyroxene + orthopyroxene + amphibole ± olivine + spinel. Gabbros are composed of clinopyroxene + orthopyroxene + amphibole + plagioclase …

Biostratigraphic Analysis Across The Eocene-Oligocene Boundary In The Southern Hellenic Thrace Basin (Lemnos Island, North Aegean Sea), Sofia Kostopoulou, Angelos Maravelis, Avraam Zelilidis
Turkish Journal of Earth Sciences
The time interval of the sedimentation in the southern Hellenic Thrace Basin (Lemnos Island, northeast Aegean Sea) was studied, based on the qualitative analysis of calcareous nannoplankton and quantitative analysis of planktonic foraminifera. The samples were collected from 4 different stratigraphic sections (Ifestia, Panagia, Kaspaka, and Kaminia). The biostratigraphic analyses on both calcareous nannoplankton and planktonic foraminifera reveal an age of Late Eocene-Early Oligocene (Priabonian-Rupelian). In particular, the Eocene-Oligocene boundary is recorded at the lower part of the turbiditic system, in the Ifestia section. The present study offers the first taxonomic analysis of planktonic foraminifera of this age in the …

Geochemistry And Source Characteristics Of Dehsard Mafic Volcanic Rocks In The Southeast Of The Sanandaj-Sirjan Zone, Iran: Implications For The Evolution Of The Neo-Tethys Ocean, Mohammadali Nazemei, Mohsen Arvin, Sara Dargahi
Turkish Journal of Earth Sciences
The Late Jurassic-Early Cretaceous Dehsard mafic volcanic rocks crop out in the southeastern Sanandaj-Sirjan Zone (SSZ), composed primarily of basalts and basaltic andesite with subordinate dolerite. They are influenced to some degree by hydrothermal alteration under zeolite-greenschist facies. Using fairly immobile trace elements, the mafic volcanic rocks show subalkaline (tholeiitic) affinities. They commonly have similar designs with somewhat strong enrichment in light rare earth elements (LREEs) and large ion lithophile elements (LILEs) and depletion in high field strength elements (HFSEs; e.g., Nb, Ta, Ti) and nearly flat heavy rare earth element (HREE) patterns. The negligible or absence of negative Eu …

Turkish Journal of Earth Sciences
Medium- and high-K calc-alkaline magmatism of the Shurab (southeast Qom city) and Garmsar (northwest Garmsar city) areas occurred within the Lower Red Formation in the Central Basin behind the Urumieh-Dokthar Magmatic Arc. In terms of whole-rock geochemical analyses and in agreement with the petrographic features, all representative samples of the Shurab area are classified into three groups: group 1 with mainly intergranular texture comprises basalt/trachybasalt, while groups 2 and 3 with trachytic and porphyritic textures, respectively, have basaltic trachyandesite composition. The overall major constituents are plagioclase with composition in the range from An49Ab23 to An75Ab47, clinopyroxene with composition in the …

The Bouguer gravity anomaly map of Turkey shows relatively high values around the Çumra region, Konya. This area has a flat topography and a thick cover of sediments despite being seated on a suture zone formed between Anatolide and Tauride Platforms after the Neo-Tethys Ocean closed. High Bouguer gravity anomalies indicate an anomalous mass excess buried under the flat topography. In the present study, the gravity anomaly is studied using several analysis and processing methods in order to understand and infer its possible sources. Spectral analysis of the anomaly showed that the mass should be buried at a depth of …
