Monetary Policy In Good Times And In Bad: Empirical Evidence From Pakistan, Haider Ali

CBER Conference

A significant body of literature explores and establishes the impact of monetary policy on output and prices, at least in the short run. However, the subsequent question is whether this effect is symmetric concerning the various states of the economy (see, Tenreyro and Thwaites, 2016; Bernstein, 2021; Eichenbaum et al., 2022; among others). This study contributes to the literature on state-dependent (non-linear) effects of unanticipated monetary policy shocks according to two important features of the economy. The amount of slack in the economy and the amount of the public-sector footprint in the market. Evaluating state-dependent effects is crucial because assuming …

Governments possess vast repositories of both structured and unstructured data across multiple domains such as the judiciary, parliaments, and civil bureaucracy. However, these potential goldmines remain untapped due to inadequate data management capabilities and a lack of appreciation for the necessity of high-quality data. The research identifies key issues in public data …

The Energy Efficiency Price Premium Of Residential Buildings In Three Italian Regions, Elena Giarda, Demetrio Panarello

CBER Conference

The aim of this paper is to investigate whether a higher energy efficiency of residential buildings translates into higher house prices in Italy. We employ novel, and almost unexploited, data on Energy Performance Certificates of three Italian regions (EmiliaRomagna, Lombardy and Piedmont) and merge them with house prices and socioeconomic variables at various aggregation levels. The relationship between house prices and energy efficiency is estimated by means of hedonic regression models, quantile regressions and fixed effects panel data models. Our results reveal the existence of an energy-efficiency price premium in the three regions, with significant differences among them. Heterogeneity is …

Virtual Water Trade: Theory And An Empirical Application, Sultan Sat, Harun Uçak

Throughout human history, water has been a determining factor in all human actions. In fact, it is seen that the oldest civilizations were established near rivers. There have been mutual effects between civilizations and water, and lifestyles have changed due to these effects. Today, access to usable water is becoming increasingly difficult. The water problem that arises due to some qualitative and quantitative negativities in a country is spreading to other countries with a butterfly effect under the influence of increasing globalization. This situation removes the water problem from being a local problem and turns it into a global problem. …

Does Tourists’ Perception Of Social Responsibility Awareness Shape Tourists’ Environmental Behavior: A Case Study In A High Mountain Region, Amjad Ali

CBER Conference

Tourism has emerged as a crucial source of livelihood for high mountain communities in Pakistan, leading to a notable increase in tourist influx over the past few years (Ali and Shedayi, 2023). This growth has created numerous income-generating opportunities for local communities, particularly in the hotel and transport sectors, offering substantial employment to the local population. However, tourism has significant adverse environmental impacts on destinations, especially fragile mountain areas (Ali, 2021). Irresponsible tourist behavior exacerbates these adverse effects (Juvan & Dolnicar, 2017; Lee et al., 2013). Therefore, understanding tourist behavior is crucial for effective destination management and policymaking. Developing and …

Bridging The Gap: An Action Research Pilot Study On Confidence Building For Women Design Students In Higher Education, Pia Mcfindlay, Ashton Margarete Moseley, Oratile Rose Mokgatla

Journal of International Women's Studies

Women are significantly underrepresented in the design industry globally, particularly in tech-driven industries like industrial design, despite an increasing number of women design graduates. While there are various factors that influence this underrepresentation, recent studies identify a general lack of confidence among women as a major contributing aspect. Women students tend to have lower self-assessments compared to their male peers, leading to limiting behaviours and barriers to pursuing opportunities in tech-based fields, which thus perpetuates gender disparity in design fields and STEAM. To address this disparity, the Industrial Design department at the University of Johannesburg in South Africa launched the …

The Afro-American And The Constitution: Colonial Times To The Present, James L. Watson

Maine Law Review

The theme of this essay is the Afro-American and the Constitution: Colonial Times to the Present. When I was told about this theme, my first reaction was to follow the advice of the famous black philosopher, Satchel Paige, who said, "Don't look back because what is behind you might be catching up." My discipline, however, forced me to look back at the Constitution and particularly how it has affected black Americans.

An Integrative Framework For Coopetition-Based Scenarios, Marko Budler

Economic and Business Review

The interplay of cooperation and competition (“coopetition”) in supply chains is well studied. However, little is known about the established and evolving scenarios that exist among supply-chain actors in the presence of coopetition. The paper draws on the resource-based view and game-theoretic reasoning to develop an integrative framework with two aims. First, to classify coopetition-based scenarios with varying levels of complementarity and lastingness and to enhance the analysis of the scenarios. Second, as theoretically argued and demonstrated with a focus group discussion, the framework is developed to assist supply chain actors in strategically managing coopetition—by identifying a particular scenario and …

Pharmacists can play a significant role in identifying and deprescribing cognitive-impairing medications through cognitive-focused medication reviews or as part of comprehensive medication management. Multiple tools exist to help pharmacists and other practitioners identify these medications, yet a comprehensive description of these tools has not been undertaken. We searched EBSCO MEDLINE, PubMed, EMBASE, CINAHL, and PsycInfo from inception to August 4, 2023, using search terms relative to medications and cognition. Studies were included if they detailed a tool to assess the cognitive burden of a medication regimen. Abstracts …

Moderate Physical Perspectivalism, Emily Adlam

Philosophy Faculty Articles and Research

Recent developments in the foundations of physics have given rise to a class of views suggesting that physically meaningful descriptions must always be relativized to a physical perspective. In this article, I distinguish between strong physical perspectivalism, which maintains that all facts must be relativized to a perspective, and moderate physical perspectivalism, which maintains that all empirically meaningful descriptions must be relativized to a perspective. I argue that scientific evidence and philosophical considerations support moderate physical perspectivalism over strong physical perspectivalism. In particular, motivations connected to epistemic humility and the social nature of science are more compatible with the moderate …

Physical Properties Of Aqueous Imide-Based Electrolyte Solutions, Mollie Harr

Honors Capstones

In order to observe the effects that cations have on the physical properties of -TFSI [-bis(trifluoromethane sulfonyl)imide] based salts, four salts (LiTFSI, NaTFSI, Mg(TFSI)2, and Al(TFSI)3) were selected for testing. The data gathered shows that when the anion is large and bulky like -TFSI, the size of the cation does not have a large effect on the physical properties, but the oxidation state of the cation may have a significant effect. The ion-ion interactions, such as collisions, aggregation, and repulsion are more significant when the cation has a higher oxidation state due to the increased ratio of anion per molecule …

Physics-Informed Transfer Learning For Process Control, Samuel Arce Munoz

Theses and Dissertations

In the realm of process control, managing complex systems with limited prior knowledge presents significant challenges, particularly in environments where traditional mechanistic models are either unavailable or computationally prohibitive. This work explores the integration of deep transfer learning with system identification and Model Predictive Control (MPC) to develop control strategies that are both data-efficient and computationally streamlined. Initially, Long Short-Term Memory (LSTM) networks are employed to create approximate MPC controllers by leveraging transfer learning from a source system to a target system, demonstrating that transfer learning can achieve comparable performance to traditional MPC methods with reduced training data. Building upon …

Conditional Cooperation With Longer Memory, Nikoleta E. Glynatsi, Ethan Akin, Martin A. Nowak, Christian Hilbe

Mathematics and Statistics Faculty Research & Creative Works

Direct reciprocity is a wide-spread mechanism for the evolution of cooperation. In repeated interactions, players can condition their behavior on previous outcomes. A well-known approach is given by reactive strategies, which respond to the coplayer's previous move. Here, we extend reactive strategies to longer memories. A reactive-n strategy takes into account the sequence of the last n moves of the coplayer. A reactive-n counting strategy responds to how often the coplayer cooperated during the last n rounds. We derive an algorithm to identify the partner strategies within these strategy sets. Partner strategies are those that ensure mutual cooperation without exploitation. …

Coke Decomposition Kinetic Model Of Spent Hydrodesulfurization Catalysts, Aymen Zween, Zaidoon Shakor, Bashir Sherhan

Journal of Applied Sciences and Nanotechnology

Recycling residue hydrodesulfurization (HDS) catalysts is essential due to frequent deactivation. Petroleum coke's high ignition temperature and complex combustion behavior stem from its graphite-like structure and low volatile matter. This study investigates petroleum coke combustion and oxidation kinetics with metal catalysts. Data from HDS catalysts (5% Co-10% Mo/active kaolin and 5% Co-10% Mo/active bentonite) are crucial for industrial regenerator simulations. Iraqi mineral clays, treated and loaded with cobalt and molybdenum, were used in HDS reactions of Iraqi gas oil with 10200 ppm sulfur at 360°C, 12 bar, and WHSV of 2 h⁻¹. Spent catalysts, coated with coke, were analyzed, and …

Characterizing Full-Time, Non-Tenure-Track Teaching Faculty In Biology, Desiree Forsythe, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Institutions of higher education play a major role in teaching undergraduate students. Historically, most courses have been taught by tenure-track (TT) faculty who may also be responsible for research or scholarly activities. However, a recent shift from “teaching-intensive” TT faculty to “teaching-only” contingent faculty off the tenure track has highlighted the importance of understanding the experiences of contingent faculty. While there have been an increasing number of studies examining the experiences of part-time contingent faculty, few studies have directly surveyed the increasing number of full-time, non-tenure-track (NTT) teaching faculty in science, technology, engineering, and mathematics (STEM) to capture their experiences, …

Directed Evolution Of Hedgehog Protein Autoprocessing Activity: Combined Experimental & Computational Approach, Ted Kuke

Undergraduate Honors Theses

Sonic hedgehog protein is vital for embryonic development while also being linked to multiple cancers and holoprosencephaly. The native reaction of hedgehog is a sterolysis reaction whereby cholesterol binds to the HhC catalytic domain and attacks the HhN signaling domain, resulting in a covalent HhN-cholesterol signaling product. The structure of the sterol recognition region (SRR) of Sonic Hedgehog, where cholesterol binds, is currently unknown. In this thesis, I used directed evolution to select a triple mutant of Hedgehog’s catalytic HhC domain, (D46H, Q150H, A196T), which is over 5000 times more catalytically efficient at reacting with epicoprostanol (ECP), a non-native substrate …

Predicting Chaotic Systems With Quantum Echo-State Networks, Erik Connerty, Ethan N. Evans, Gerasimos Angelatos, Vignesh Narayanan

Publications

Recent advancements in artificial neural networks have enabled impressive tasks on classical computers, but they demand significant computational resources. While quantum computing offers potential beyond classical systems, the advantages of quantum neural networks (QNNs) remain largely unexplored. In this work, we present and examine a quantum circuit (QC) that implements and aims to improve upon the classical echo-state network (ESN), a type of reservoir-based recurrent neural networks (RNNs), using quantum computers. Typically, ESNs consist of an extremely large reservoir that learns high-dimensional embeddings, enabling prediction of complex system trajectories. Quantum echo-state networks (QESNs) aim to reduce this need for prohibitively …
