The Effect Of Price-Based Demand Response On Carbon Emissions In European Electricity Markets: The Importance Of Adequate Carbon Prices, Markus Fleschutz, Markus Bohlayer, Marco Braun, Gregor Henze, Michael D. Murphy

Publications

Price-based demand response (PBDR) has recently been attributed great economic but also environmental potential. However, the determination of its short-term effects on carbon emissions requires the knowledge of marginal emission factors (MEFs), which compared to grid mix emission factors (XEFs), are cumbersome to calculate due to the complex characteristics of national electricity markets. This study, therefore, proposes two merit order-based methods to approximate hourly MEFs and applies them to readily available datasets from 20 European countries for the years 2017–2019. Based on the calculated electricity prices, standardized daily load shifts were simulated which indicated that carbon emissions increased for 8 …


Estimating School-Level Effects Of Mandatory Student Grade Retention Policies Using Latent Growth Curve Modeling, Matthew Koziol Aug 2021

Estimating School-Level Effects Of Mandatory Student Grade Retention Policies Using Latent Growth Curve Modeling, Matthew Koziol

Dissertations

Mandatory grade retention for poor-performing readers has been a disputed practice for decades. Since the early-2000s, state-level mandatory grade retention policies have proliferated. In 18 states and Washington, D.C. mandatory grade retention exists for students in the third grade who fail an end-of-year standardized reading exam. These policies are based on research that suggests students who do not read by the third-grade are at much greater risk of dropping out of school prior to receiving a high-school degree. Mandatory grade retention policies use a gatekeeper mechanism at the end of the third grade to ensure that students who are not …

On The Efficacy Of Knowledge Graph Completion Methods, Accuracy Measures And Evaluation Protocols, Farahnaz Akrami

Computer Science and Engineering Dissertations - Archive

In the active research area of employing embedding models for knowledge graph completion, particularly for the task of link prediction, most prior studies used some specific benchmark datasets to evaluate such models. Most triples in those datasets belong to reverse and duplicate relations, which exhibit high data redundancy due to semantic duplication, correlation, or data incompleteness. This is a case of excessive data leakage—a model is trained using features that otherwise would not be available when the model needs to be applied for real prediction. There are also Cartesian product relations for which every triple formed by the Cartesian product …
