Phenylpropionic Acid Produced By Gut Microbiota Alleviates Acetaminophen-Induced Hepatotoxicity, Sungjoon Cho, Xiaotong Yang, Kyoung-Jae Won, Vanessa A. Leone, Eugene B. Chang, Grace Guzman, Hyunwoo Lee, Hyungyoung Jeong

Purdue University Libraries Open Access Publishing Fund

The gut microbiota affects hepatic drug metabolism. However, gut microbial factors modulating hepatic drug metabolism are largely unknown. In this study, using a mouse model of acetaminophen (APAP)-induced hepatotoxicity, we identified a gut bacterial metabolite that controls the hepatic expression of CYP2E1 that catalyzes the conversion of APAP to a reactive, toxic metabolite. By comparing C57BL/6 substrain mice from two different vendors, Jackson (6J) and Taconic (6N), which are genetically similar but harbor different gut microbiotas, we established that the differences in the gut microbiotas result in differential susceptibility to APAP-induced hepatotoxicity. 6J mice exhibited lower susceptibility to APAP-induced hepatotoxicity …

Factor Structure Of School Readiness Skills: Conceptual Vs. Statistical Distinctions, Robert Duncan, Kirsten L. Anderson, Jennifer Finders, David J. Purpura, Sara A. Schmitt

Purdue Center for Early Learning Faculty and Staff Publications

Introduction: School readiness skills are a broad set of abilities that children develop in early childhood that support achievement once they enter formal schooling. Three components of school readiness skills are of focus in the current study: executive function (EF), language/literacy, and mathematics. The current study examines to what extent 13 direct assessments of these skills statistically align with theoretical models for distinct construct- and timepoint-specific latent factors.

Methods: The sample included 684 children (52.34% male; 42% Black/African American; M_age = 4.80 years in the fall of prekindergarten) assessed in the fall and spring of the prekindergarten year.

Developmental Pb Exposure Increases Ad Risk Via Altered Intracellular Ca2+ Homeostasis In Hipsc-Derived Cortical Neurons, Junkai Xie, Shichen Wu, Hailey Szadowski, Sehong Min, Yang Yang, Aaron B. Bowman, Jean-Christophe Rochet, Jennifer L. Freeman, Chongli Yuan

Purdue University Libraries Open Access Publishing Fund

Exposure to environmental chemicals such as lead (Pb) during vulnerable developmental periods can result in adverse health outcomes later in life. Human cohort studies have demonstrated associations between developmental Pb exposure and Alzheimer's disease (AD) onset in later life which were further corroborated by findings from animal studies. The molecular pathway linking developmental Pb exposure and increased AD risk, however, remains elusive. In this work, we used human iPSC-derived cortical neurons as a model system to study the effects of Pb exposure on AD-like pathogenesis in human cortical neurons. We exposed neural progenitor cells derived from human iPSC to 0, …

Implementing Ipm In Crop Management Simultaneously Improves The Health Of Managed Bees And Enhances The Diversity Of Wild Pollinator Communities, Jacob R. Pecenka, Laura Ingwell, Christian H. Krupke, Ian Kaplan

Purdue University Libraries Open Access Publishing Fund

Impacts of insecticide use on the health of wild and managed pollinators have been difficult to accurately quantify in the field. Existing designs tend to focus on single crops, even though highly mobile bees routinely forage across crop boundaries. We created fields of pollinator-dependent watermelon surrounded by corn, regionally important crops in the Midwestern US. These fields were paired at multiple sites in 2017–2020 with the only difference being pest management regimes: a standard set of conventional management (CM) practices vs. an integrated pest management (IPM) system that uses scouting and pest thresholds to determine if/when insecticides are used. Between …

Exploring The Future Of Sars-Cov-2 Treatment After The First Two Years Of The Pandemic: A Comparative Study Of Alternative Therapeutics, Benjamin Ayodipupo Babalola, Oluwamayowa Samuel Akinsuyi, Elizabeth Oreoluwa Folajimi, Folakemi Olujimi, Ahmed Adebisi Otunba, Bruno Chikere, Ibitayo Ajayi Adewumagun, Tosin Emmanuel Adetobi

Purdue University Libraries Open Access Publishing Fund

One of the most pressing challenges associated with SARS-CoV-2 treatment is the emergence of new variants that may be more transmissible, cause more severe disease, or be resistant to current treatments and vaccines. The emergence of SARS-CoV-2 has led to a global pandemic, resulting in millions of deaths worldwide. Various strategies have been employed to combat the virus, including neutralizing monoclonal antibodies (mAbs), CRISPR/Cas13, and antisense oligonucleotides (ASOs). While vaccines and small molecules have proven to be an effective means of preventing severe COVID-19 and reducing transmission rates, the emergence of new virus variants poses a challenge to their …

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 …

Cardiac Output And Stroke Volume From The Pneumocardiogram: A New Mechanistic Insight And Practical Calculation, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

This paper presents a new and more complete mechanism for the genesis of the pneumocardiogram—a record of the small oscillations in airflow in the trachea and upper airways accompanying each heartbeat. This signal may be the basis of a simple, inexpensive and noninvasive measure of cardiac stroke volume; however, research into its practical use has languished because of poor understanding of its underlying cause and meaning. This paper explains the genesis of the pneumocardiogram, based upon net changes in intrathoracic blood volume during the cardiac cycle, together with low pass filtering of the volume signal by airway resistance and lung-chest …

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 …

Rapid And Efficient Computation Of Cell Trajectories During Ultrasonic Focusing, Charles F. Babbs, Mary V. Lang

Weldon School of Biomedical Engineering Faculty Working Papers

This biophysical analysis explores the first-principles physics of movement of white blood cell sized particles, suspended in an aqueous fluid and experiencing progressive or standing waves of acoustic pressure. In many current applications the cells are gradually nudged or herded toward the antinodes of the standing wave, providing a degree of acoustic focusing and concentration of the cells in layers perpendicular to the direction of sound propagation. Here the underlying biomechanics of this phenomenon are analyzed specifically for the viscous regime of water--as opposed to air--and for small diameter microscopic spheroids such as living cells--as opposed to large diameter, macroscopic …

Young Indigenous Entrepreneurs- Supporting Changemakers Through Entrepreneurship And Advocacy Of Indigenous Issues, Anita Lakra, Emily Wang, Shagufta Farheen

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

Indigenous youth are reclaiming their language, customs and land. They are at the forefront of Canada’s fastest-growing population, yet continue to face barriers in health, education and justice systems. Indigenous tourism often exploits Indigenous communities. However, self-driven Indigenous tourism is an opportunity for Indigenous communities to strengthen their culture and economy. Many Indigenous youth aspire to start businesses. Their products are often sold not just nationally, but also to international customers. Hence, a program that provides financial literacy courses and personalized business advice can support young Indigenous entrepreneurs. Based on the experience of a young Indigenous entrepreneur who sells beadwork …

Contextualizing And Integrating Practices: Reclaiming Authenticity Lost From Translating Workplace Engineering Practices Into K-12 Standards, Anne E. Leak, Lindsay M. Owens, Kelly Norris Martin, Benjamin M. Zwickl

Journal of Pre-College Engineering Education Research (J-PEER)

K-12 students need to become familiar with engineering because 21st-century careers integrate engineering practices across all science, technology, engineering, and mathematics (STEM) fields. While the Next Generation Science Standards (NGSS) emphasize learning real science and engineering practices, further work is needed to authenticate engineering for K-12 education. The NGSS are presented in a way that merges a single general practice with a core disciplinary idea and cross-cutting concept. Based on this framing and underlying epistemology, NGSS engineering practices are often implemented as overgeneralized, isolated, and largely context-neutral. Yet, in the STEM workplace, practices are rarely done in isolation from one …

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 …

Destinations’ Recovery Marketing Campaigns In Response To Pandemics, Eli Avraham

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

The Covid-19 pandemic has altered the paradigm of risk and recovery management but it is just one of many pandemics to have impacted destinations during the last two decades. This study examine how destination officials combated the image crises that followed SARS-2003, H1N1 Swine flu 2009-10, Zika 2016-17 and Covid-19. The literature dealing with combating pandemics has focused on the actual management of either a specific pandemic or regional aspects of a pandemic and less on the recovery marketing and image repair aspect. As a result, tourism academic literature has a shortage of image repair theoretical frameworks addressing multi-case health-related …

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 …

Guest Attitudes In The Covid Era: Does Socioeconomic Status Impact The Acceptance Of Hotels' Green Practices?, Faranak Memarzadeh, Priya Raman

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

As the hotel industry is one of the sectors that is heavily affected by the pandemic, it is critical to discover which characteristics of guests’ priorities have transformed due to COVID-19, including guests' mindset about hotels’ green practices.

To offer the most effective sustainable service in the pandemic era, hoteliers need a clear perception of guests’ viewpoints on hotels’ green practices. Besides the guests’ demographic information, which helps in understanding their opinion about green service in the COVID-19 time, their socioeconomic status could predict the layout of their mindset and perceptions of the service in this specific period of time.

Can Digital Marketing On Instagram Help To Promote Sustainable Travel? Abstract, Jacques Bulchand-Gidumal Professor, Armin Brysch Professor

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

The contribution of digitalization and digital platforms to tourism sustainability is a timely topic. In this research we analyze if a digital platform such as Instagram could contribute and be used as a tool to promote sustainability by destinations and by travelers. To this aim, we implement a methodology comprised of four steps: identifying the most recognized sustainable destinations in the world (i.e. Slovenia, New Zealand and Costa Rica), downloading and analyzing the last posts from the official accounts of the DMOs of these destinations, identifying the most frequently used hashtags related to sustainable tourism (#ecoturismo, #ecotourism, #sustainabletravel, #ecotravel and …

Instagram Travel Influencers Coping With Covid-19 Travel Disruption, Andrei Kirilenko, Katarzyna Emin, Karen Tavares

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

A significant portion of today’s marketing is done through social media influencers, that is, through bloggers with established online credibility in a certain area who are recognized and followed by a sizable online audience. In the travel and hospitality industry, the influencer marketing is primarily done through Instagram due to its emphasis on visual images rather than texts. Covid-19 related travel restrictions and shrinking social media advertisement in travel industry have heavily impacted travel influencers, reducing their income and forcing many out of business. We present the outcomes of a study of the top 150 online travel influencers. The analysis …

The Covid-19 And The Stock Market Behaviour Of The Tourism Sector In Spain., Isabel Carrillo-Hidalgo, Juan Ignacio Pulido-Fernández, Jose Luis Durán-Román, Jairo Casado-Montilla

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

The global pandemic caused by COVID-19, declared in March 2020, has had a dramatic impact on tourism, especially in Spain, as it was one of the first countries affected by the pandemic, as well as being one of the world’s biggest tourist destinations. Stock market values are responding to the evolution of the pandemic, especially in the case of tourist companies, so being able to quantify this relationship allows us to predict the effect of the pandemic on shares in the tourism sector, improving the response to the crisis. To this end, a model has been developed to predict the …

What Drives Satisfaction And Dissatisfaction Of Hotel Guests? An Exploratory Analysis Based On Tripadvisor, Carlos Díaz-Santamaría, Jacques Bulchand-Gidumal Professor, Santiago Melián-González

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

Understanding the drivers of hotel guest satisfaction and dissatisfaction is basic for hotel managers. In this research, we use a large database of more than 30,000 reviews that were posted on TripAdvisor to investigate this issue. We use Power BI to assign a sentiment score to each review and to extract the main phrases from them. This allows us to create two datasets of words and phrases (one derived from the reviews of satisfied guests and one derived from the reviews of dissatisfied guests) in order to compare them. In order to compare both datasets, we perform a quantitative analysis. …

Tourists’ Meaning Of Sustainability As A Tool For Segmentation. A Biosphere Reserve Case Study, Juan Ignacio Pulido-Fernández, Yaiza López-Sánchez, Isabel Carrillo-Hidalgo, Jose Luis Durán-Román

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

This paper provides empirical evidence on the potential use of the meaning of sustainability for the tourist in segmentation studies. The analysis has been applied to a nature destination, specifically, in the “Sierras de Cazorla, Segura y Las Villas” Biosphere Reserve. In the first place, this research identifies, through a cluster analysis, three segments of tourists based on what the tourist considers sustainability to be (level of knowledge and commitment, as well as its implications for the destination), analyzing for each segment their sociodemographic and socioeconomic variables and their willingness to pay to improve the sustainability of destinations.

The results …
