Inferring Social Media Users’ Demographics From Profile Pictures: A Face++ Analysis On Twitter Users, Soon-Gyo Jung, Jisun An, Haewoon Kwak, Joni Salminen, Bernard J. Jansen

Research Collection School Of Computing and Information Systems

In this research, we evaluate the applicability of using facial recognition of social media account profile pictures to infer the demographic attributes of gender, race, and age of the account owners leveraging a commercial and well-known image service, specifically Face++. Our goal is to determine the feasibility of this approach for actual system implementation. Using a dataset of approximately 10,000 Twitter profile pictures, we use Face++ to classify this set of images for gender, race, and age. We determine that about 30% of these profile pictures contain identifiable images of people using the current state-of-the-art automated means. We then employ …

Enterprise Social Media Use And Impact On Performance: The Role Of Workplace Integration And Positive Emotions, Murad Moqbel, Fiona Fui-Hoon Nah

Research Collection School Of Computing and Information Systems

Organizations struggle to find ways to improve employees’ performance. To date, little research has empirically examined the relationship between enterprise social media use and knowledge workers’ performance. Using social capital theory and the broaden-and-build theory of positive emotions as our theoretical framework, we investigate the relationship between enterprise social media use and knowledge workers’ performance. We tested our research model by collecting data from employees working for a large information technology firm in the Midwestern United States and analyzing the data using a structural equation modeling approach. The results suggest that enterprise social media use can increase workplace integration, which …

A Hybrid Parallel Approach To High-Performance Compression Of Big Genomic Files And In Compresso Data Processing, Sandino N. Vargas Pérez

Dissertations

Due to the rapid development of high-throughput low cost Next-Generation Sequencing, genomic file transmission and storage is now one of the many Big Data challenges in computer science. Highly specialized compression techniques have been devised to tackle this issue, but sequential data compression has become increasingly inefficient and existing parallel algorithms suffer from poor scalability. Even the best available solutions can take hours to compress gigabytes of data, making the use of these techniques for large-scale genomics prohibitively expensive in terms of time and space complexity.

This dissertation responds to the aforementioned problem by presenting a novel hybrid parallel approach …

Uncovering New Links Through Interaction Duration, Laxmi Amulya Gundala

Boise State University Theses and Dissertations

Link Prediction is the problem of inferring new relationships among nodes in a network that can occur in the near future. Classical approaches mainly consider neighborhood structure similarity when linking nodes. However, we may also want to take into account whether the two nodes we are going to link will benefit from that by having an active interaction over time. For instance, it is better to link two nodes � and � if we know that these two nodes will interact in the social network in the future, rather than suggesting �, who may never interact with �. Thus, the …

Cultivating Community Interactions In Citizen Science: Connecting People To Each Other And The Environment, Bret Allen Finley

Boise State University Theses and Dissertations

Citizen science leverages a distributed user-base which participates in crowd-sourced scientific inquiry. Geotagger is a citizen science project that allows people to collaboratively investigate the natural world around them and share their findings. Citizens are rarely compensated for their work and individual contributors can feel isolated which leads to motivation problems. This thesis focuses on engaging citizen scientists and motivating their contributions via social interaction and engagement. As a part of this work, a number of social enhancements have been developed as extensions to the existing Geotagger project. These enhancements and their effect on social engagement were evaluated using in-field …

Research-Based Stem Educator Professional Development Rubrics For The Selection Of High-Quality Professional Development: A Mixed Methods Study Of Teacher Perceptions And Outcomes, Angela Hemingway

Boise State University Theses and Dissertations

Idahoans failed to recognize approximately $240M in 2016 when over 3,800 STEM (science, technology, engineering, and math) jobs, with a median wage of $30 per hour, went unfilled. This further caused Idaho to lose $14M in state income tax receipts from these unclaimed positions (Idaho Department of Labor, 2016). To mitigate these economic losses, the Idaho STEM Action Center (STEM AC) was created to develop the STEM-skilled workforce that Idaho employers demand. High-quality, STEM-educator professional development (PD) is a critical component in ensuring students are equipped with the skills required to successfully thrive in the workforce and fill industry demands. …

Variance: Secure Two-Party Protocol For Solving Yao's Millionaires' Problem In Bitcoin, Joshua Holmes

Boise State University Theses and Dissertations

Secure multiparty protocols are useful tools for parties wishing to jointly compute a function while keeping their input data secret. The millionaires’ problem is the first secure two-party computation problem, where the goal is to securely compare two private numbers without a trusted third-party. There have been several solutions to the problem, including Yao’s protocol [Yao, 1982] and Mix and Match [Jakobsson and Juels, 2000]. However, Yao’s Protocol is not secure in the malicious model and Mix and Match unnecessarily releases theoretically breakable encryptions of information about the data that is not needed for the comparison. In addition, neither protocol …

The Use Of Visual Arts In World Language Instruction To Increase Student Motivation And Attitude, Marilena Bevilacqua Martello

Boise State University Theses and Dissertations

Because of the complexity and changeability that characterize languages, language learners face a number of various factors in their quest to acquire a new language. Nevertheless, it is the level of motivation and personal attitude toward language learning that will determine their rate of success (Dörnyei & Csizér, 1998). The purpose of this study was to find out (1) whether there was a relationship between the use of visual art in world language instruction and student motivation, and (2) whether student writing skills improved when visual art was used for Content Based Instruction.

Impacts Of Anthropogenic Noise On Litter Chemistry And Decomposition Processes In A Semi-Arid Ecosystem, Peggy Martinez

Boise State University Theses and Dissertations

Chronic anthropogenic noise in ecosystems can change avian/arthropod/plant interactions, but it is unclear how changes in herbivory pressure affects functional traits of plants. We asked how anthropogenic noise, mediated through changes in arthropod abundance, altered timing of leaf senesce, chemical composition (i.e. C/N ratios, total phenolics) and decomposition rates of leaf litter in Wyoming big sagebrush (Artemisia tridentata spp. wyo.). Additionally, we asked if changes in arthropod abundance altered secondary metabolites (i.e. monoterpenes) in foliage. We broadcasted recorded gas compressor station noise (24hrs/day) from April through October 2015 in a sagebrush steppe ecosystem of Idaho, USA. We quantified …

Optimizing Barrier Removal To Restore Connectivity In Utah’S Weber Basin, Maggi Kraft

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

River barriers, such as dams, culverts and diversions are important for water conveyance, but disrupt river ecosystems and hydrologic processes. River barrier removal is increasingly used to restore and improve river habitat and connectivity. Most past barrier removal projects prioritized individual barriers using score-and-rank techniques, neglecting the spatial structure and cumulative change from multiple barrier removals. Similarly, most water demand models satisfy human water uses or, only prioritize aquatic habitat, failing to include both human and environmental water use benefits. In this study, a dual objective optimization model identified in-stream barriers that impede quality-weighted aquatic habitat connectivity for Bonneville cutthroat …

Testing The Test: Expanding The Dialogue On Workplace Writing Assessment, Lindsay Elizabeth Tanner

Theses and Dissertations

This project is a case study of writing assessment practices in a particular workplace called "High Hits," a local search engine optimization (SEO) company. The writing tests given to new hires serve a parallel purpose to academic placement exams, in that they are a high-stress, high-risk situation that aims to evaluate writer ability rather than the quality of the completed task (Haswell 242, Elbow 83, Moss 110). However, while academic assessment measures ability with the aim to improve the students' learning, workplace assessment is driven by market forces and is seen in terms of return on investment. This case study …

Phased-Array Feed Instrumentation And Processing For Astronomical Detection, Interference Mitigation, And Transient Parameter Estimation, Richard Allen Black

Theses and Dissertations

Radio astronomy, the survey and study of naturally occurring astronomical radio signals, is a challenging field in terms of engineering requirements. The typical astronomical signal of interest is incredibly faint, resulting in very low signal-to-noise ratios (SNRs) on the order of -30 dB or lower. To detect such signals, one must have an uncommonly low and stable receiver noise temperature, high gain through large aperture reflectors, and state-of-the-art signal processing algorithms. One must also be able to mitigate the effects of interference, the presence of which, even if extremely weak, can completely mask the faint astronomical signals of interest. To …

Multiple Target Tracking In Realistic Environments Using Recursive-Ransac In A Data Fusion Framework, Jeffrey Dyke Millard

Theses and Dissertations

Reliable track continuity is an important characteristic of multiple target tracking (MTT) algorithms. In the specific case of visually tracking multiple ground targets from an aerial platform, challenges arise due to realistic operating environments such as video compression artifacts, unmodeled camera vibration, and general imperfections in the target detection algorithm. Some popular visual detection techniques include Kanade-Lucas-Tomasi (KLT)-based motion detection, difference imaging, and object feature matching. Each of these algorithmic detectors has fundamental limitations in regard to providing consistent measurements. In this thesis we present a scalable detection framework that simultaneously leverages multiple measurement sources. We present the recursive random …
