Department of Chemistry Faculty Publications

Nonaqueous dispersions of graphene nanoplatelets (GrNPs) can be used to prepare thin films and coatings free of surfactants, but typically involve polar organic solvents with high boiling points and low exposure limits. Here, we describe the mechanochemical exfoliation and dispersion of GrNPs in volatile aprotic solvents such as ethyl acetate (EtOAc) and acetone, which rank favorably in green solvent selection guides. GrNPs in powder form were exfoliated with a solvent on a horizontal ball mill for 48 h and then sonicated at moderate power to produce suspensions in excess of 300 μg/mL with minimum loss of dispersion stability over 7 …

Exploring Scenario-Based Assessment Of Students' Global Engineering Competency: Building Evidence Of Validity Of A China-Based Situational Judgment Test, Kirsten A. Davis, Brent Jesiek, David B. Knight

School of Engineering Education Faculty Publications

Background

Engineers operate in an increasingly global environment, making it important that engineering students develop global engineering competency to prepare them for success in the workplace. To understand this learning, we need assessment approaches that go beyond traditional self-report surveys. A previous study (Jesiek et al., Journal of Engineering Education 2020; 109(3):1–21) began this process by developing a situational judgment test (SJT) to assess global engineering competency based in the Chinese context and administering it to practicing engineers.

Purpose

We built on this previous study by administering the SJT to engineering students to explore what prior experiences related to their …

Learning In A Crisis Moment: A Randomized Controlled Trial In Emergency Bystander Intervention, Caitlin Mcgaffick, Noor Gulrajani, Nan Kong, Nicole Adams

Purdue University Libraries Open Access Publishing Fund

Background

Opioid overdose is the leading cause of injury-related death in the United States. Individuals who overdose outside of clinical settings have more positive clinical outcomes when they receive naloxone, an opioid antagonist, from a bystander as an early intervention before emergency personnel arrive. However, there is a gap in knowledge about successful instantaneous learning and intervention in a real-life stressful environment. The objective of this study is to explore the efficacy of different instructional delivery methods for bystanders in a stressful environment. We aim to evaluate which methods are most effective for instantaneous learning, successful intervention, and improved clinical …

Narratives And Expert Information In Agenda-Setting: Experimental Evidence On State Legislator Engagement With Artificial Intelligence Policy, Daniel S. Schiff, Kaylyn J. Schiff

Department of Political Science Faculty Publications

Are narratives as influential in gaining the attention of policymakers as expert information, including for complex, technical policy domains such as artificial intelligence (AI) policy? This pre-registered study uses a field experiment to evaluate legislator responsiveness to policy entrepreneur outreach. In partnership with a leading AI think tank, we send more than 7300 U.S. state legislative offices emails about AI policy containing an influence strategy (providing a narrative, expert information, or the organization's background), along with a prominent issue frame about AI (emphasizing technological competition or ethical implications). To assess engagement, we measure link clicks to further resources and webinar …

The Role Of Region And Religious Tradition In Predicting Individuals’ Expressions Of Faith In The Workplace, Jacqui Frost, Christopher P. Scheitle, Elaine Howard Ecklund, Denise Daniels

Purdue University Libraries Open Access Publishing Fund

While many variables might influence an individual’s willingness to express their faith in the workplace, the role of regional context has not been fully considered. The different geographical regions in the U.S. consist of unique demographics and cultures that could shape an individual’s expression of faith at work. Moreover, these regional effects might be moderated by an individual’s specific religious tradition. Using data from a survey of U.S. adults featuring oversamples of Jewish and Muslim individuals, we utilize two unique measures of religious expression—displaying/wearing religious items at work and talking about religion at work—to assess the roles of region and …

When Those With Privacy Concerns Show Stronger In-Group Favoritism: Using Personal Information From In-Group And Out-Group Members To Identify Terrorist Threats, Torsten Reimer, Nathanael Johnson

Purdue University Libraries Open Access Publishing Fund

Terrorist threats and attacks provide major risks and sources of public crises in the 21st century. New probabilistic computing technologies possess the capability of increasing the success of identifying terrorist threats and solving cybersecurity and encryption problems more efficiently. However, to identify terrorist threats, these technologies would require the use of a large amount of personal data, which cause potential concerns for privacy. We offer a social-identity explanation of public support for the detection of terrorist threats through the use of online personal data. A survey study (N = 1,204) revealed strong support for the provided social-identity explanation of …

Work-Life Flexibility Policies From A Boundary Control And Implementation Perspective: A Review And Research Framework, Ellen Ernst Kossek, Matthew B. Perrigino, Brenda A. Lautsch

Department of Management Faculty Publications

Although management research on work-life flexibility policies has occurred for over 40 years, it is underdeveloped with inconsistent results. We argue that this is due to theorizing that—but not measuring whether—policy use increases boundary control; a fragmented literature examining a range of policies (either individually or bundled) without comprehensive integration; and an under-examination of policy implementation effectiveness. Drawing on boundary theory, we inductively review 338 studies to organize the work–life flexibility policy literature around a boundary control and implementation framework. Our framework derives a taxonomy of types of boundary control, identifies implementation stages, considers the importance of policy bundling, and …

Employing A Transitivity Violation Detection Algorithm To Assess Best–Worst Scaling Designs, Courtney Bir, Nicole Olynk Widmar, Natalya Slipchenko, Addison Polcyn, Christopher A. Wolf

Department of Agricultural Economics Faculty Publications

When choosing a partial factorial design for best–worst scaling (BWS) or other discrete choice experiment, researchers are faced with design size choices. This work investigates differences between two case 1 (object) BWS choice experiment designs that varied in choice set size and number of questions. Using a random-parameter logit model, preference shares were determined and statistically compared between models. The number of transitivity violations occurring between the experimental designs was analyzed employing a newly developed directed graph algorithm. The relative importance consumers placed on dairy milk attributes differed between the designs studied. The design presenting fewer attributes per choice set …

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

The COVID-19 virus has caused the biggest worldwide economic crisis since the Great Depression of the 1930s and a “zero tourism” situation with catastrophic consequences. Many authors analyzed the economic impacts of the COVID-19 pandemic, but none of them have specifically examined Spain and government actions and public policies taken to fight the pandemic. Through the case study methodology, this paper presents a literature review of the most up-to-date studies on the impacts of the COVID-19 global pandemic. Secondly, we specify the different public intervention measures implemented by national, regional, and local authorities in Spain. Finally, we set out the …

Waste Treatment Facility Location For Hotel Chains, Dolores R. Santos-Peñate, Rafael R. Suárez-Vega, Carmen Florido De La Nuez

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

Tourism generates huge amounts of waste. About half of the waste generated by hotels is food and garden bio-waste. This bio-waste can be used to make compost and pellets. In turn, pellets can be used as an absorbent material in composters and as an energy source. We consider the problem of locating composting and pellet-making facilities so that the bio-waste generated by a chain of hotels can be managed at or close to the generation points. An optimization model is applied to locate the facilities and allocate the waste and products, and several scenarios are analysed. The study shows that, …

Quantifying The Impact Of Airlines Exit In Tourism Destinations. The Cases Of Monarch And Thomas Cook, Ubay Pérez-Granja, Juan Luis Eugenio-Martin

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

We analyze the impact on tourists’ arrivals after the bankruptcies of Monarch Airlines and Thomas Cook. It draws on arrivals from the UK to Canary Islands and it employs a univariate and multivariate structural time series with level interventions. More interestingly, after Monarch exit, the policymakers applied a laissez faire strategy, which resulted in a 93.04% net loss of their level of traffic in Tenerife. However, after Thomas Cook exit, the policymakers intervened in the market proposing incentives to the incumbent airlines to cover the loss. It resulted in a 34.72% net loss of Thomas Cook level of traffic. Moreover, …

Insearch Of Local Indigenous Dishes: An Analysis Of Casual Dinning Restaurants, South Africa, Sisa Ngcwangu Mr

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

This paper explores menus of casual dining restaurants in Mbombela, Mpumalanga Province, South Africa. The focus of the paper is to search for local indigenous dishes with an aim to find out if these restaurants include local cuisine in their menus. Literature has established that food is one of the primary motivators for travellers when making a decision as to which destination to travel to. Restaurants are places where most tourists will have their meals during their stay in a destination. This creates an opportunity for a region to further entrench itself in the memory of the tourist, thus increase …
