Issues Of Social Data Analytics With A New Method For Sentiment Analysis Of Social Media Data, Zhaoxia Wang, Victor J. C. Tong, David Chan

Research Collection School of Social Sciences

Social media data consists of feedback, critiques and other comments that are posted online by internet users. Collectively, these comments may reflect sentiments that are sometimes not captured in traditional data collection methods such as administering a survey questionnaire. Thus, social media data offers a rich source of information, which can be adequately analyzed and understood. In this paper, we survey the extant research literature on sentiment analysis and discuss various limitations of the existing analytical methods. A major limitation in the large majority of existing research is the exclusive focus on social media data in the English language. There …

A Humean Account Of Testimonial Justification, Shane Ryan

Research Collection School of Social Sciences

I argue that a Humean account can make sense of the phenomenology associated with testimonial justification; the phenomenology being that in standard cases hearers regularly simply accept a testifier’s assertions as true – hearers don't engage in monitoring. The upshot is that a Humean account is in a better position dialectically than is usually supposed. I provide some background to the debate before setting out two challenges facing accounts of testimonial justification. The first challenge is to provide an account that accords with the phenomenology of testimonial reception; the second challenge is to provide an account that can make sense …

A Smart Web Crawler For A Concept Based Semantic Search Engine, Vinay Kancherla

Master's Projects

The internet is a vast collection of billions of web pages containing terabytes of information arranged in thousands of servers using HTML. The size of this collection itself is a formidable obstacle in retrieving information necessary and relevant. This made search engines an important part of our lives. Search engines strive to retrieve information as relevant as possible to the user. One of the building blocks of search engines is the Web Crawler. A web crawler is a bot that goes around the internet collecting and storing it in a database for further analysis and arrangement of the data.

Sexual Violence And Sub-Saharan Migrants In Morocco: A Community-Based Participatory Assessment Using Respondent Driven Sampling, Ines Keygnaert, Abdessamad Dialmy, Altay Manço, Jeroen Keygnaert, Nicole Vettenburg, Kristien Roelens, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: The European Union contracted Morocco to regulate migration from so-called “transit migrants” from Morocco to Europe via the European Neighbourhood Policy. Yet, international organisations signal that human, asylum and refugee rights are not upheld in Morocco and that many sub-Saharan migrants suffer from ill-health and violence. Hence, our study aimed at 1) investigating the nature of violence that sub-Saharan migrants experience around and in Morocco, 2) assessing which determinants they perceive as decisive and 3) formulating prevention recommendations.

Methods: Applying Community-Based Participatory Research, we trained twelve sub-Saharan migrants as Community Researchers to conduct in-depth interviews with peers, using Respondent …

Currie, Therese Dowswell, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Maternal mortality has declined by nearly half since 1990, but over a quarter million women still die every year of causes related to pregnancy and childbirth. Maternal-health related targets are falling short of the2015 Millennium Development Goals and a post-2015 Development Agenda is emerging. In connection with this, setting global research priorities for the next decade is now required.

Methods: We adapted the methods of the Child Health and Nutrition Research Initiative (CHNRI) to identify and set global research priorities for maternal and perinatal health for the period 2015 to 2025. Priority research questions were received from various international …

Implementation Of Evidence-Based Antenatal Care In Mozambique: A Cluster Randomized Controlled Trial: Study Protocol, Leonardo Chavane, Mario Merialdi, Ana Pilar Betrán, Jennifer Requejo-Harris, Eduardo Bergel, Alicia Aleman, Mercedes Colomar, Maria Luisa Cafferata, Alicia Carbonell, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Antenatal care (ANC) reduces maternal and perinatal morbidity and mortality directly through the detection and treatment of pregnancy-related illnesses, and indirectly through the detection of women at increased risk of delivery complications. The potential benefits of quality antenatal care services are most significant in low-resource countries where morbidity and mortality levels among women of reproductive age and neonates are higher. WHO developed an ANC model that recommended the delivery of services scientifically proven to improve maternal, perinatal and neonatal outcomes. The aim of this study is to determine the effect of an intervention designed to increase the use of …

Langmuir Probe Instrument Suite For Mesosphere Turbulence Experiment Mission, Adam Blake

Doctoral Dissertations and Master's Theses

The Langmuir probe technique is the predominant in-situ plasma diagnostic technique, and is arguably the only measurement technique that is universally own on every sounding rocket investigation. Earth's mesosphere region (80-120 km) is a host of many dynamic phenomena such as the noctilucent clouds, breaking gravity waves, inversion layers, settlement of mesospheric smoke particles, etc. As such it is critical to have a comprehensive suite of plasma diagnostics that can unambiguously measure various plasma parameters.

This thesis deals with the development and testing of three different Langmuir probe implementations suitable for investigation of the mesosphere which are to be launched …

Characterization Of Electron Number Density Of Rocket Exhaust Plumes Through Microwave Transmissions, Jorge Torres

Doctoral Dissertations and Master's Theses

Charged rocket plumes generally exceed the length of their source vehicles, and offer lightning a favorable path to ground. Rocket plumes enhance the induced transient currents in flight electronics, and increase the risk of vehicle failure. The affinity of lightning to the plume can be associated with the plume's electrical properties, which are coupled to plasma characteristics including the electron number density. However, the electron number density of rocket plumes is not well-known. In this study, the electron number density is characterized through data from static rocket firings. A model of the plume in finite difference time domain (FDTD) simulations …

Human Behavior During Spaceflight: Evidence From An Analog Environment, Kenny Mikael Arnaldi

Doctoral Dissertations and Master's Theses

Spaceflight offers a multitude of stressors to humans living and working in space, originating from the external space environment and the life-support system. Future space participants may be ordinary people with different medical and psychosocial backgrounds who may not receive the intense spaceflight preparation of astronauts. Consequently, during a mission, a space participant’s mood and behavior could differ from a trained astronaut. This study was an exploratory research project that used an artificial habitat to replicate an orbital environment and the activities performed by humans in space. The study evaluated whether the type of environment affects mood and temperament. Two …

Development Of A System Architecture For Unmanned Systems Across Multiple Domains, Charles Randall Breingan Jr.

Doctoral Dissertations and Master's Theses

In the unmanned systems industry, there is no common standard for systems components, connections and relations. Such a standard is never likely to exist. Needless to say, a system needs to have the components that are required for the application, however, it is possible to abstract the common functionality out of an individual implementation. This thesis presents a universal unmanned systems architecture that collects all of the common features of an unmanned system and presents them as a set of packages and libraries that can be used in any domain of unmanned system operation. The research and design of the …

Factors Impacting Success In Ninth Grade Algebra I For High School Students, James M. Lamie

Electronic Theses and Dissertations

The implementation of the Common Core State Standards (CCSS, 2013), No Child Left Behind Act of 2001, and the Race to the Top initiative of 2009 has placed a greater emphasis on high stakes testing. A renewed emphasis on math education for all students and their ability to succeed in high school mathematics place new challenges on today’s classroom teachers. Although the belief is that with new standards and best teaching strategies students will improve their test scores, there are multiple factors that can serve as deterrents to the success in mathematics for at-risk high school students (Balfanz, 2009). The …

Impulsivity, Venturesomeness, And Pride: Potential Moderators Of The Relationship Between Childhood Trauma, Substance Use, And Physical Aggression, Joshua P. Hatfield

Electronic Theses and Dissertations

Impulsivity, venturesomeness, and pride variables were examined as potential moderators of the associations between childhood trauma and physical aggression, alcohol use and physical aggression, and drug use and physical aggression. Participants (n = 457) were college students recruited from a university in the Southeast. It was hypothesized that childhood trauma, alcohol use, and drug use would be associated with increased scores of physical aggression. In addition, it was hypothesized that impulsivity, venturesomeness, authentic pride, and hubristic pride would moderate these relationships. Linear, multivariate hierarchical regression analyses were used to examine these variables as potential moderators. Hypotheses concerning hubristic pride as …

Collaborative Models Of Care In The Appalachian Region Of Tennessee: Examining Relationships Between Level Of Collaboration, Clinic Characteristics, And Barriers To Collaboration, Jeffrey Ellison

Electronic Theses and Dissertations

Decades of research have shown that there are significant advantages to maintaining close communicative and collaborative relationships between primary care and behavioral health providers. Fiscal, structural, and systemic barriers, however, often restrict the degree to which such interprofessional collaboration can occur. In the present study the authors examined relationships between primary care clinics in the Appalachian region’s characteristics (i.e., clinic type, rurality, and clinic size), barriers (i.e., fiscal, structural, and systemic) reported to using increased collaboration, and the level of collaboration used at a particular clinic.

For the present study 136 surveys were completed by providers working in primary care …

Cellular-Based Brain Pathology In The Anterior Cingulate Cortex Of Males With Autism Spectrum Disorder, Jessica D. Crawford

Electronic Theses and Dissertations

Autism spectrum disorder (ASD) now affects 1 in 68 children in the United States. Disorders within this spectrum share hallmark deficits in verbal and nonverbal communication, repetitive behavior, and social interaction. The cause of ASD is still unknown. Even though hundreds of genetic abnormalities have been identified in ASD, these markers account for less than 1% of all ASD cases. Researchers continue to search for pathological markers common to all or most cases of ASD. The research presented in this dissertation used a novel combination of state-of-the-art methods to investigate brain pathology in ASD. Postmortem anterior cingulate cortex (ACC) from …

Novel Insights Into The Role Of The Smoothened Cysteine Rich Domain In Hedgehog Signalling, Rajashree Rana

Theses and Dissertations (ETD)

The Hedgehog (Hh) signal transduction pathway functions as one of the key developmental pathways and deranged Hh signalling is associated with numerous cancer and tumor conditions. The Smoothened (Smo) G protein coupled receptor (GPCR) functions as the signal transducer of the Hh pathway and is the most attractive drug target of the pathway. The structure of the Smo receptor includes seven membrane spanning domains, extracellular and intracellular loops connecting the membranous domains and the extracellular cysteine rich domain (CRD). The extracellular CRD of the Smo receptor is homologous to the Frizzled (FzD) CRD. The FzD CRD interacts with the physiological …

Mrp4-Dependent Regulation Of Fibroblast Migration, Chandrima Sinha

Theses and Dissertations (ETD)

Roles of cyclic nucleotides and cyclic nucleotide-dependent signaling molecules in regulating several signaling pathways including cell migration have long been known. However, the new and revolutionary concept is that it is not just the absence or presence of cyclic nucleotides, but a highly coordinated balance between these molecules regulates cell migration. Multi-drug resistance protein 4 (MRP4), is a member of the large family of ATP binding cassette (ABC) transporter proteins, that localizes to the plasma membrane and functions as a nucleotide efflux transporter and thus plays a pivotal role in the regulation of intracellular cyclic nucleotide dynamics. In our study …

The Role Of Mcl-1 In The Heart: Gateway From Life To Death, Xi Wang

Theses and Dissertations (ETD)

MCL-1 is an essential BCL-2 family member that promotes the survival of multiple cellular lineages, but its role in cardiac muscle has remained unclear. Here, we have demonstrated that cardiac-specific ablation of Mcl-1 results in a rapidly fatal, dilated cardiomyopathy preceded by loss of myofibrils and cardiac contractility, abnormal mitochondria ultrastructure, defective mitochondrial respiration, and impaired autophagy. Genetic ablation of both pro-apoptotic effectors (Bax and Bak) could largely rescue the lethality and impaired cardiac function induced by Mcl-1 deletion. However, Mcl-1-, Bax-, and Bak-deficient hearts still revealed mitochondrial ultrastructural abnormalities and displayed deficient mitochondrial respiration, and are hypersensitive to chronic …

Genetic And Chemical Dissection Of Bloodbrain Barrier Development In Zebrafish, Robyn Anne Umans

Theses and Dissertations (ETD)

The blood-brain barrier (BBB) maintains a homeostatic environment as well as prohibits the entrance of xenobiotics into the brain. Because of these qualities, drug delivery is a fundamental challenge for the treatment of many diseases of the central nervous system (CNS). Along with limiting the access of therapeutics into the brain, the BBB is also impaired in CNS pathologies. Understanding the molecular cues that are essential for healthy BBB development and integrity may reveal targets for drug delivery leading to decreased progression or possible treatment of many detrimental CNS diseases. While the central features of the BBB have been accepted, …
