Businesses also actively monitor and manage their online reviews to build trust in their brand and make it more likely that customers will buy. Traditional approaches for assessing customer behavior, such as market research surveys and focus groups, …
Digital Discrimination In The Sharing Economy: Evidence, Policy, And Feature Analysis, Miroslav Tushev
Digital Discrimination In The Sharing Economy: Evidence, Policy, And Feature Analysis, Miroslav Tushev
LSU Doctoral Dissertations
Applications (apps) of the Digital Sharing Economy (DSE), such as Uber, Airbnb, and TaskRabbit, have become a main facilitator of economic growth and shared prosperity in modern-day societies. However, recent research has revealed that the participation of minority groups in DSE activities is often hindered by different forms of bias and discrimination. Evidence of such behavior has been documented across almost all domains of DSE, including ridesharing, lodging, and freelancing. However, little is known about the under- lying design decisions of DSE systems which allow certain demographics of the market to gain unfair advantage over others. To bridge this knowledge …

A Study On User Demographic Inference Via Ratings In Recommender Systems, Changbin Li
A Study On User Demographic Inference Via Ratings In Recommender Systems, Changbin Li
LSU Master's Theses
Everyday, millions of people interact with online services that adopt recommender systems, such as personalized movie, news and product recommendation services. Research has shown that the demographic attributes of users such as age and gender can further improve the performance of recommender systems and can be very useful for many other applications such as marketing and social studies. However, users do not always provide those details in their online profiles due to privacy concern. On the other hand, user interactions such as ratings in recommender systems may provide an alternative way to infer demographic information. Most existing approaches can infer …

The Impact Of Student Centered Learning Strategies In Middle School Earth Science, Zane Jay Whittington
LSU Master's Theses
Research continues to reinforce that student centered classrooms and interactive engagement (IE) strategies, when used effectively, can produce considerable gains compared to traditional instruction methods. In this study, IE strategies, primarily modeling instruction, were compared to traditional instruction in a middle school classroom to determine if IE strategies would have an impact in two specific areas: graphing ability and science reasoning skills. Class mean scores on tests were compared over time to show that IE strategies produced greater gains in graphing and science reasoning than traditional instruction for one group. The other group did not see significant differences in graphing …

Metacognition And Its Effect On Learning High School Calculus, Bonnie Sue Bergstresser
LSU Master's Theses
The following paper discusses the effect of metacognitive training sessions on students’ calculus retention. Students in two high school classes participated. The students in both classes were then given lessons on a chapter without metacognitive training and lessons on a subsequent chapter with training in a set of metacognitive skills. After the latter chapter students scored higher on a post-test and expressed desire to incorporate the skills they learned into their other classes.
Toward Digitizing The Human Experience : A New Resource For Natural Language Processing, Jerry Scott Weltman
Toward Digitizing The Human Experience : A New Resource For Natural Language Processing, Jerry Scott Weltman
LSU Doctoral Dissertations
A long-standing goal of Artificial Intelligence is to program computers that understand natural language. A basic obstacle is that computers lack the common sense that even small children acquire simply by experiencing life, and no one has devised a way to program this experience into a computer. This dissertation presents a methodology and proof-of-concept software system that enables non-experts, with some training, to create simple experiences. For the purposes of this dissertation, an experience is a series of time-ordered comic frames, annotated with the changing intentional and physical states of the characters and objects in each frame. Each frame represents …

Due to the destruction of the damaging hurricanes of 2005, Katrina and Rita, more effort has gone into the rebuilding and prevention of future disasters along the Louisiana coast than ever before. This research focuses on the use of wetlands, in the ten coastal parishes of Louisiana, as a mitigation effort aiding in the protection of coastal communities. Using content analysis and decision support software, a wetland ranking was created that represents how wetlands are utilized and protected within each parish. Criteria gathered from the plans include how many times wetlands were mentioned, collaboration with the state and other agencies, …
Is A Student's Conceptual Knowledge Affected By Their Vocabulary Instruction?, Daniel C. Cox
Is A Student's Conceptual Knowledge Affected By Their Vocabulary Instruction?, Daniel C. Cox
LSU Master's Theses
The following paper explores the possible relationship between the manner in which a student is taught vocabulary in a high school physics classroom and the ability of those students to correctly answer physics conceptual questions. Two high school physics classes taught by the same teacher (eight or nine students in one and seventeen in the other) received identical instruction throughout multiple units with the exception of vocabulary instruction. Differences were observed in the students’ ability to correctly answer conceptual questions in only one topic, heat. The students did not get better at answering a question concerning a phase change or …
Evaluation Of The Effectiveness Of Cooperative Learning Structures In Improving Students' Performance, Jonah Njenga
Evaluation Of The Effectiveness Of Cooperative Learning Structures In Improving Students' Performance, Jonah Njenga
LSU Master's Theses
In a desperate attempt to improve high school classroom performances, recently, schools have begun to move towards incorporating cooperative learning strategies into their classrooms. Generally, cooperative learning strategies can be described as the use of small groups to encourage learners work together and accomplish shared goals and subsequently maximize theirs and others’ potential. In an attempt to evaluate the effectiveness of this strategy on classroom learning, this study compares the gains in means of scores between a group taught using cooperative learning strategies and another group taught using non-cooperative learning strategies. Fifty-three students taking Algebra I were given a pretest …

Ontology-Based Methodology For Error Detection In Software Design, Allyson M. Hoss
LSU Doctoral Dissertations
Improving the quality of a software design with the goal of producing a high quality software product continues to grow in importance due to the costs that result from poorly designed software. It is commonly accepted that multiple design views are required in order to clearly specify the required functionality of software. There is universal agreement as to the importance of identifying inconsistencies early in the software design process, but the challenge is how to reconcile the representations of the diverse views to ensure consistency. To address the problem of inconsistencies that occur across multiple design views, this research introduces …
Atomic And Electronic Structure Of Bulk Intermetallic And Heteroepitaxially Grown Surface Alloys, Orhan Kizilkaya
Atomic And Electronic Structure Of Bulk Intermetallic And Heteroepitaxially Grown Surface Alloys, Orhan Kizilkaya
LSU Doctoral Dissertations
It has been well documented that the surfaces of solids may differ from their bulk counterpart. The symmetry that a bulk possesses is broken at the surface. Due to this broken symmetry in the reduced dimension of the surface, the energetic of the surface also differs from the bulk counterpart. Reconstruction, charge redistribution, and surface alloying are phenomena that minimize the surface free energy. Surface properties of scientifically and technologically important bimetallic systems are the main focus of this dissertation. Specifically, surfaces of bulk alloy or heteroepitaxially grown metal-on-metal systems have been investigated primarily with two indispensable surface techniques, scanning …

Ontogeny And Intervals Of Development In Five Reef-Associated Species Of Blenny From The Northern Gulf Of Mexico (Teleostei: Blenniidae), James G. Ditty
LSU Doctoral Dissertations
I examined patterns and timing of ontogeny and relative growth in five species of blenny (Teleostei: Blenniidae) from the northern Gulf of Mexico by assigning a suite of discrete character state scores to ontogenetic events (10 external traits; 218 total specimens). This is the first study to evaluate developmental patterns in reef-associated fishes relative to the timing of metamorphosis and settlement by applying scaling techniques and statistical methods to quantify, differentiate, and select criteria for defining intervals of development across taxa. Blennies settle at a common state of ontogeny and share a common pattern of body and fin/cirrus growth. Three …
Experience-Based Language Acquisition: A Computational Model Of Human Language Acquisition, Brian Edward Pangburn
Experience-Based Language Acquisition: A Computational Model Of Human Language Acquisition, Brian Edward Pangburn
LSU Doctoral Dissertations
Almost from the very beginning of the digital age, people have sought better ways to communicate with computers. This research investigates how computers might be enabled to understand natural language in a more humanlike way. Based, in part, on cognitive development in infants, we introduce an open computational framework for visual perception and grounded language acquisition called Experience-Based Language Acquisition (EBLA). EBLA can “watch” a series of short videos and acquire a simple language of nouns and verbs corresponding to the objects and object-object relations in those videos. Upon acquiring this protolanguage, EBLA can perform basic scene analysis to generate …

Predicting Electron Insert Output Factors At Nominal And Extended Source To Surface Distance, Ahmet Bulut
LSU Master's Theses
Two Varian linear accelerators were used to test the modified sector-integration method. This method can predict the electron insert factor for arbitrary inserts at different source to surface distances (SSD). The effective source distances (SSDeff) and insert factors (IF) for several accelerators are compared. The relationship of IF and SSDeff for machine type, energy, cone size, insert size and SSD is presented. The results were fed into the electron output determination module of an existing monitor unit calculator (MUCalc) which uses the modified sector integration method. Prediction and measurements were compared for various clinical inserts at several …
