Inclusive and exclusive electron scattering data analysis from Jefferson Lab experiment E12-14-012
… observations of neutrino oscillation, neutrino experiments have come a long way toward precise measurements of the neutrino oscillation parameters, but some obstacles still remain. The next generation of oscillation experiments, including the Deep Underground Neutrino Experiment (DUNE), will be …

The force of law: Effects of legislation on formal and interpersonal discrimination towards gay and lesbian job applicants
… paradigms (resume survey, field study, and lab experiment) that equalize the extent of sexual orientation disclosure with and without legal protections. Additionally, we expand the form of discrimination studied to include not only traditional formal measures but also more subtle, …

Using Gaze Tracking to Tackle Duplicate Questions on Community Based Question Answering Websites: A Case Study of Ifixit
… to post a new duplicate question. The first lab experiment where this web page was redesigned and compared to the original one was conducted on 8 participants. Results confirmed that participants were more likely to find an answer to their question on the redesigned page. A second experiment, …

Framing Norms and Beliefs: Experimental Approaches to Tax Compliance, Gender Identity, Religious Behavior, and Risk-Taking.
… thesis consists of four chapters. The first is a laboratory experiment investigating the link between tax evasion and social norms. The second chapter conducts another lab experiment examining gender preconceptions and misrepresentation in strategic contexts. In the third chapter, I use …

Can Threats and Fear Foster Security? Cognitive and Emotive Forces of Fear Appeals on Information Security Behavior
… These models were tested in a series of experimental studies to investigate how threat-based message components can drive emotion and cognition to motivate appropriate security behavior. The first study consisted of a lab experiment that manipulated each message component (threat …

Framing for creativity : the impact of framing a task for gains and losses on risk perceptions and creative performance
… 231 undergraduate students participated in a lab experiment to assess the role of taks framing on creative performance. A modified version of Antes and Mumford (2010)'s creativity in-basket was used, with either a gain or loss-framed manipulation. It was hypothesized that a mediated moderation …

Essays On The Motivating Effects Of Goals In Accounting
… as a goal by workers, affects motivation. In a lab experiment, participants exerted more effort on a task when facing short goal horizons. The shorter horizons allowed workers to achieve more goals in a given time, and this motivated them. However, as uncertainty in the task was increased, …

Understanding the influence of individual behaviour and social networks in sustainability transitions.
… from a cross-sectional online survey (N=474), a lab experiment (N=134) and an agent-based model (ABM) to explore how a change towards sustainable food purchasing may be achieved in society. The methodological approach of this thesis is quantitative confirmatory and exploratory. The online survey, …

Experiments on emotions, matching, and decision-making
… I study how matching affects confidence. In collaboration with Friederike Mengel (University of Essex and Lund University) and Mehmet Yigit Gurdal (Bogazici University), we use an experiment that allows us to identify the effect of being matched with others of either similar or dissimilar …

Isolating Confounding Abiotic and Biotic Effects on the Phenotype on Physa Acuta Snails
… smaller apertures. In a reciprocal transplant lab experiment that crossed flow regime and crayfish predator cues, I tested for the underlying mechanisms responsible for the observed phenotypic differences. I found no evidence for plasticity in relation to flow regime. However, there was a …

The iLab service broker : a software infrastructure providing common services in support of Internet accessible laboratories
Remote laboratories that are accessible via the Internet are becoming a common phenomenon in higher education institutions. This thesis describes the iLab Service Broker architecture, a software infrastructure that supports these Internet-accessible labs by providing a number of services that …

Transient thermo-fluid model of meniscus behavior and slag consumption in steel continuous casting
… cycle. First, the model is applied to a lab experiment done with a “mold simulator” to verify the transient temperature-field predictions. Next, the model is verified by matching with available literature and plant measurements of slag consumption. A reasonable agreement has been observed …

Group conflict and intergroup contact
… beneficial to both communities, and that collaboration increased voluntary intergroup contact, intergroup trust, and feelings of security for the participants and for nonparticipants living in the same villages as the participants. The second paper uses a lab experiment to test a specific …

The diet and growth of a leaf-shredding caddisfly, Pycnopsyche, in streams of contrasting disturbance histories
… (disturbed) forest at Coweeta Hydrologic Laboratory in southwestern North Carolina. The objective was to examine whether Pycnopsyche larvae grew better on fast-decaying leaf types more prevalent in the disturbed streams (e.g., black birch) because leaf-eating insects (shredders) in a …

Identity, Intergroup Relationships, and Environmental Conflict
… Through one theoretical review, two online experiments and one in-lab experiment I explore, integrate and test theoretically grounded strategies for reducing the defensive information processing that can exacerbate intergroup divisions in multi-stakeholder settings. The specific objectives …

Adaptive thermal comfort and its application in mixed mode buildings: The case of a hot-summer and cold-winter climate in China
… adaptive thermal comfort based on the availability of adaptations, in particular behavioural adaptations, which needs quantifications of individual adaptation processes and of interactions between them. The fundamental argument of this method is that exercising an adaptive behaviour leads …

Development of Potential Remote Coal Mine Fire Response Measures: Use of Multiple Passive Source Tracers and Simulation of High Expansion Foam Flow in Simulated Gob Material
… foam flow in simulated gob material with a lab experiment. The experiment was replicated in the CFD software, OpenFOAM, to validate the methods for calculation of the Darcy and Forchheimer values. The results of this study provide a tested methodology for a future full scale modeling of high …
