The Double-Edged Role Of Cognitive Reappraisal: A Moderated Mediation Model Of Manager Support And Emotional Exhaustion Among Hotel Supervisors, Han Chen, Yvette Green

Journal of Global Hospitality and Tourism

Applying the Conservation of Resources Theory and the Affective Event Theory, this study explores the interplay between perceived manager support (PMS), negative emotions, and emotional exhaustion among hotel supervisors. The study also examines the moderating role of cognitive reappraisal strategy on the above relationships. Data were collected from a sample of U.S. hotel supervisors. Results showed that negative emotions play a mediating role in the relationship between PMS and supervisors’ emotional exhaustion. Cognitive reappraisal amplified the negative effect of PMS on negative emotions, the positive relationship between negative emotions and emotional exhaustion, and the indirect effect of PMS on emotional …

Customer Food Intake: An Empirical Analysis Of Gender, Restaurant Use And Attitude Toward Fast Food Among Adolescents And Young Adults, In Nairobi, Kenya, Gerishom G. Madivoli, Rosemarie Ayuma Khayiya, Beatrice Kamau

Journal of Global Hospitality and Tourism

Fast food is the fastest- growing food category worldwide, providing young people and adolescents with a quick, cost- effective, and easily accessible alternative to home- cooked meals. There has been considerably less research into how gender, restaurant usage, and attitudes influence patterns of fast- food consumption. Moreover, the growth of the fast- food industry in every nation creates a significant environmental impetus for increasing fast food consumption and promoting unhealthy eating behaviours. If this issue is not addressed, the prevalence of lifestyle diseases such as obesity, along with the costs of managing these conditions, will escalate, particularly in Kenya. This …

Reframing Service Quality In Ai-Powered Hospitality Environments, Olena Ciftci

Journal of Global Hospitality and Tourism

The hospitality and tourism industry is experiencing a technological shift through the integration of artificial intelligence (AI), transforming both guest experiences and service operations. While AI offers hyper-personalization, efficiency, and scalability, it challenges traditional notions of service quality rooted in human interaction. This viewpoint explores the emerging concept of tech-augmented hospitality, where AI and human employees co-create guest experiences. The paper highlights key research directions for reconceptualizing service quality in the era of AI-enhanced hospitality. It argues for the development of new evaluative frameworks that encompass hybrid service models, cultural adaptability, inclusivity, and AI literacy.

Quarcs Light: Validation Of An Abbreviated Assessment Of Undergraduate Numeracy And Mathematics Affect, Isaac S. Rosenthal, Kate Follette, Vonna L. Hemmler, Catherine Sarosi, Sanlyn Buxner, Erin Galyen, Margaret Shea, Soon-Young Shimizu, Brendan Seto

Numeracy

In this study, we present evidence for the validity of a shortened form of the Quantitative Reasoning for College Science (QuaRCS) Assessment, a validated instrument assessing the numeracy and math-related affect of undergraduate students in general education/introductory science courses. Previously published analyses of QuaRCS data revealed that 1) roughly 30% of students found the assessment boring, leading to lower self-reported effort and 2) affective factors (e.g. numerical self-efficacy) were significant predictors of QuaRCS score. As a result, we reduced the length of the assessment from 25 to 15 quantitative items, and expanded the affective variable selection from three to eight …

GNSI brought together leading academics, defense experts, and international scholars for thought-provoking discussions on the strategic lessons learned from the Russia-Ukraine War, the evolving role of technology in conflict, and the impact of the war on Europe, NATO, and the rules-based international system. The war in Ukraine is not just a regional crisis; it is a harbinger of the future of warfare. In contrast to …

Gnsi Decision Brief: Building Trust In Digital Response: The Role Of Chatbots In Cybercrime Prevention Open-Source Tools For Safer Digital Reporting And Public Trust, George Burruss, Loni Hagen, Ly Dinh, Lingyao Li

GNSI Decision Briefs

Cybercrime poses a growing global threat, inflicting financial harm on individuals, businesses, and governments. In 2024 alone, the FBI's Internet Crime Complain Center (IC3) received over 800,000 complains, with reported losses exceeding $16.6 billion, a 33 percent increase from the prior year. The damage extends beyond financial loss: cybercrime undermines trust in digital systems and can cause psychological harm. Its anonymous and complex nature makes detection and prosecurtion difficult, creating low-risk, high-reward conditions for offenders.

Crisis On The Frontlines: Recruitment And Retention Challenges In Ems, Bruce J. Moeller, Michael Lozano

Florida Center for Emergency Medical Services Research Reports

Florida’s emergency medical services (EMS) and fire service agencies face an unprecedented workforce crisis. Compounded by demographic shifts, rising call volumes, and mounting mental health challenges, many EMS agencies are struggling to recruit and retain qualified personnel. Existing models of recruitment—centered on short-term bonuses or messaging emphasizing sacrifice—are failing to resonate with new generations of workers, who prioritize mental wellness, career progression, and work-life balance. Additionally, outdated training pipelines and a decline in volunteerism, especially in rural areas, have weakened the traditional workforce structure, creating gaps that threaten the stability of emergency response systems statewide.

To address these challenges, the …

Bayes In The Brain: A Review Of Everything Is Predictable: How Bayesian Statistics Explain Our World, (2024) By Tom Chivers., Michael T. Catalano

Numeracy

Tom Chivers’ Everything is Predictable: How Bayesian Statistics Explain Our World, is an interesting and wide-ranging narrative on Bayesian thinking, its history, and its applicability to both our everyday lives and the pursuit of scientific truth. Although appropriate for the non-expert, afficionados and teachers of quantitative literacy should find the plethora of examples, links to psychology as it applies to how people reason about probabilities, and even Chivers’ philosophical musings informative and thought-provoking.

Some Corrections To The Record On Lemkin’S Early Years: The Evidence From Poland, Zachary Mazur

Genocide Studies and Prevention: An International Journal

This piece addresses some misunderstandings regarding Raphael Lemkin's early years in Poland, his influences and the development of his ideas. While discussing some of the extent published information, I point out what other archival documents from Poland and the League of Nations have to say about Lemkin's past. One of the main points is that Lemkin was an unreliable narrator on his own life, and this has caused confusion.

Arts & Literature: The Destruction Of Smyrna In 1922: A Conversation With Petros Pourliakas, Author Of Salty Silk, Petros Pourliakas

Genocide Studies and Prevention: An International Journal

In 1922, the once-cosmopolitan city of Smyrna—modern-day Izmir—was engulfed in flames, marking the end of a centuries-long Hellenic presence in Asia Minor. The catastrophe, which followed the Greco-Turkish War and occurred amidst the collapse of the Ottoman Empire, resulted in the deaths of tens of thousands and the displacement of hundreds of thousands more. In his 2022 book Salty Silk, Greek author Petros Pourliakas recounts the tragedy, focusing on the humanitarian heroism that emerged in the midst of horror. I spoke with Pourliakas about his research, the moral complexities of recounting a national trauma, and the legacy of a …

Where Are The Criminologists?: The Persistent Absence Of The Field In Genocide Research, Grace Allbaugh, Susan A. Woollen, Jacqueline L. Schneider, Joanne Savage

Genocide Studies and Prevention: An International Journal

The rallying cry of “Never Again” was heard worldwide after the Nazis’ annihilation of Jews and other victims were discovered after WWII. The global community promised that the crime of genocide would be prevented and signatory parties of the United Nations Convention on the Prevention and Punishment of Genocide (December 9, 1948) would do everything in their power to prevent another Holocaust from occurring. Unfortunately the “crime of all crimes” remains an almost permanent fixture in international news while signatory parties remain reluctant to call the ongoing conditions genocide. The field of genocide studies is built upon an interdisciplinary field …

Opportunities For Growth: A Metacognitive Self-Talk Strategy That Improves Classroom Unity And Academic Attitudes, Sera Anello, Michael J. Haslip

Journal of Practitioner Research

This teacher action research study describes the development and application of the opportunities for growth teaching method to increase learner motivation, persistence, cooperation and positive self-talk among primary school students. The approach was implemented with 30 fourth graders in a Philadelphia public school classroom to foster unity, support attitudes toward academics and participation, redefine failure, and reframe challenges. Before this intervention, most of the students lacked self-regulation, self-awareness, and relationship skills needed to thrive. This study investigates how and to what effect the opportunities for growth approach shifts students’ language and mindset about academic and social challenges. Qualitative data was …

Highly Pathogenic Avian Influenza Resulted In Unprecedented Reproductive Failure And Movement Nehaviour By Northern Gannets, Noah G. Careen, Sydney M. Collins, Kyle J. N. D’Entremont, Jordan Wight, Ishraq Rahman, Kathryn E. Hargan, Andrew S. Lang, William A. Montevecchi

Marine Ornithology

In 2022, highly pathogenic avian influenza (HPAI) virus resulted in mass mortality throughout seabird colonies in the North Atlantic Ocean. While mortalities and transmission of the virus are being documented, other effects are less understood. We documented nest abandonment and unprecedented reproductive failure by Northern Gannets Morus bassanus at Cape St. Mary’s, Newfoundland and Labrador, Canada, the species’ southernmost colony. Reproductive success in 2022 was the lowest on record at 17%, which was likely a result of adults abandoning the nest and succumbing to avian influenza virus (AIV) infection. Following the AIV outbreak at Cape St. Mary’s, we also documented …

Notes On A Plover Briefly Incubating An Oystercatcher Nest In Patagonia, José O. Valdebenito

Marine Ornithology

A breeding female Two-banded Plover Charadrius falklandicus was observed incubating the eggs of a Magellanic Oystercatcher Haematopus leucopodus while the nest was unattended by the oystercatcher. The behaviour was likely triggered by the plover’s nest becoming momentarily inaccessible, and so, being in incubation mode, the bird responded by incubating the nearest nest available. This is the first report of such behaviour while the oystercatcher was nearby, and the plover nest was still active and in sight.

Effects Of A Vagrant Arctic Fox Alopex Lagopus On An Isolated Newfoundland Seabird Community, Raul Zabala Belenguer, Amy C. Wilson, Katja H. Kochvar, Sabina I. Wilhelm, Pierre-Paul Bitton

Marine Ornithology

We report predation by an Arctic Fox Alopex lagopus on two seabird species, Atlantic Puffins Fratercula arctica and Leach’s Storm Petrels Hydrobates leucorhous, nesting on Bakeapple Island, Little Fogo Islands, Newfoundland, Canada. This event took place in 2022, when a whole-island inspection revealed that fox, facilitated by over-ice invasion, killed at least 139 adult storm petrels and 8 puffin chicks. The fox also dug out 83 storm petrel and 4 puffin burrows. Breeding by seabirds on the island, which harbours some of the northernmost colonies in Newfoundland, was also largely disrupted; we documented extremely low egg and chick production values …

A Systematic Review Of Trends In Research On Seabird Behavioral Flexibility, M. Candelaria Biagiotti Barchiesi, Laura M. Biondi, German O. García

Marine Ornithology

There has been an increase in interest in the study of behavioral flexibility for its role in how organisms face disturbances and changes in their environment. However, there is not much research on this topic for seabirds, whose conservation status is affected by multiple issues related to changes in their environment. The goal of this paper was to analyze research on seabird behavioral flexibility and to identify knowledge gaps. A systematic review was conducted using academic search engines that included articles published from 1986 to 2022. In the 143 articles that were analyzed, the following were identified: publication date, family …

Medical History And Post-Release Survival Of Rehabilitated California Brown Pelicans Pelecanus Occidentalis Californicus, 2009-2019, Rebecca S. Duerr, Deborah L. Jaques, Barton G. Selby, Julie S. Skoglund, Suzanne Kosina

Marine Ornithology

California Brown Pelicans Pelecanus occidentalis californicus rehabilitated in 2009–2019 were released with metal federal and blue plastic auxiliary leg bands. Resighting data were obtained from the US Geological Survey’s Bird Banding Laboratory, International Bird Rescue’s citizen science reporting forms, and non-breeding communal roost site surveys. Medical problems and demographic data were assessed in relation to whether birds were resighted, whether they were alive at the most recent resighting, and by longevity after release. The 1418 blue-banded individuals in the study were admitted for rehabilitation and released 1 465 times, and 49.9% were resighted at least once. At the most recent …

High-Contrast Banners Designed To Deter Seabirds From Gillnets Reduce Target Fish Catch, William A. Montevecchi, Jessika Lamarre, Yann Rouxel, Marina W. Montevecchi, Robert J. Blackmore, Christina Bourne, Caleb S. Spiegel

Marine Ornithology

The incidental catch of non-target species in fishing gear (i.e., bycatch) is a global threat to sustainability and conservation in marine systems. Seabirds experience substantial bycatch mortality, with gillnets having the greatest impacts of any fishing gear. Widespread mitigation to reduce seabird bycatch in gillnet fisheries is tenuous, and information on bycatch in inshore surface-set gillnets remains a major knowledge gap. To help address these issues, we collaborated with commercial fishers to test the efficacy of high-contrast banners designed to alert seabirds. In waters of Newfoundland, Canada, banners were attached to surface-set gillnets for Atlantic Herring Clupea harengus and were …

Breeding Microhabitat Patterns Among Sympatric Tropical Larids, Antonio Garcia-Quintas, Dennis Denis, Christophe Barbraud, Sophie Lanco Bertrand

Marine Ornithology

The selection of breeding microhabitat (nesting sites) affects successful reproduction in seabirds, yet the process of nesting-site selection in sympatric tropical species remains poorly known. During the 2021 breeding season, we assessed nesting-site selection among five larid species at three cays of Cuba and quantified explanatory variables. Random forest classification models were used to assess which landscape features among eight variables best explained site selection by each species. Patterns were clear for most species, especially the highly gregarious Roseate Tern Sterna dougallii, Royal Tern Thalasseus maximus, and Sandwich Tern T. sandvicensis. Patterns were consistent among the study cays. Dominant plant …

Nocturnal Flight Activity By Northern Gannets Morus Bassanus In Response To Predator Presence, Kyle J.N. D’Entremont, William A. Montevecchi

Marine Ornithology

The Northern Gannet Morus bassanus typically flies only during the day, with minimal flight activity following civil twilight. Here we document nocturnal flight activity by Northern Gannets in response to predation risk by Eastern Coyotes Canis latrans. Eight parental gannets were fitted with GPS/time-depth recorders on 15 July 2021 at mainland nest sites at Cape St. Mary’s, Newfoundland, Canada. Previously, among 506 foraging trips in 2019 and 2020 that were investigated using biologging, only two were initiated at night, suggesting nocturnal departures for foraging are very rare at this colony. Then, however, killings of chicks by coyotes occurred within our …

A Test Of Mechanisms Of Population Differentiation In Gannets (Morus Spp.) Using Comparative Phylogeography And Morphometrics, Victoria L. Friesen, Rebecca Brunt, James A. Morris-Pocock, Drew Sauve, Allan J. Baker, Timothy P. Birt, William S. Davidson, Kyle H. Elliott, William A. Montevecchi

Marine Ornithology

The relative importance of gene flow, genetic drift, and natural selection in driving genetic divergence of local populations, as well as the factors that disrupt gene flow in natural populations, are uncertain. Comparative analyses enable us to test explicit hypotheses regarding the roles of these factors. Gannets (Morus spp.) include three morphologically and ecologically similar seabird species: the Cape Gannet M. capensis, which breeds in southern Africa; the Australasian Gannet M. serrator, which breeds in southeastern Australia and New Zealand; and the Northern Gannet M. bassanus, which breeds in the North Atlantic. We assessed the extent of differentiation in mitochondrial …

On-Land Foraging By Leach's Storm Petrels Oceanodroma Leucorhoa Coincides With Anomalous Weather Conditions, Kyle J.N. D’Entremont, Robert J. Blackmore, Sydney M. Collins, Dave Brown, Ian L. Jones, Bruce Mactavish, Sabina I. Wilhelm, William A. Montevecchi

Marine Ornithology

We describe the first known documentation of on-land foraging by Leach’s Storm Petrels Oceanodroma leucorhoa, a behaviour that has been documented only once before among members of the family Hydrobatidae. During a rain/windstorm from 15 to 17 July 2020 in eastern Newfoundland, individuals fed on coastally spawning and beach-cast capelin Mallotus villosus. This behaviour occurred in conjunction with a marine heatwave in the species’ foraging range. Examination showed that wrecked birds were emaciated with negligible stomach contents. This finding, combined with the abnormal weather and foraging behaviour, suggests that these birds were in a weakened state preceding stranding in coastal …

No Evidence Of Habitat Effect On Clutch Size, Egg Quality, And Hatching Success Of The Yellow-Legged Gull Larus Michahellis At A Micro-Spatial Scale, Sergio Delgado, Nere Zorrozua, Juan Arizaga

Marine Ornithology

In colonial seabirds, the nest substrate that is available and, in particular, the vegetation cover around the nest, are important environmental factors that drive an individual’s nesting selection process and, ultimately, reproductive performance. Using data collected during three consecutive years in a Yellow-legged Gull Larus michahellis colony from the Bay of Biscay, Spain, we tested whether clutch size, egg volume, and hatching success covaried with the proportion of vegetation cover around nests. We found no effect of vegetation cover on breeding performance. Laying date showed a positive effect on egg volume and a negative effect on hatching success and the …

Ocean Heat Wave Induces Breeding Failure At The Southern Breeding Limit Of The Northern Gannet Morus Bassanus, William A. Montevecchi, Paul M. Regular, Jean-François Rail, Kyran Power, Chris Mooney, Kyle J.N. D’Entremont, Stefan Garthe, Leanne Guzzwell, Sabina I. Wilhelm

Marine Ornithology

We document unprecedented abandonments and breeding failures by Northern Gannets in eastern Canada at Cape St. Mary’s, Bonaventure Island, and the Magdalen Islands. These events were associated with a marine heat wave during chick rearing in the late summer of 2012. The rapid onset of abandonment at Cape St. Mary’s also coincided with intense lightning and thunder during an overnight storm. Parental desertions at all colonies were transient, resolving over a period of weeks, and appeared to be food-related, resulting in the poorest breeding success on record for each of these colonies. The Northern Gannet’s primary prey during the breeding …

Spatiotemporal Characterization Of Non-Breeding Great Shearwaters Ardenna Gravis Within Their Wintering Range, Kevin D. Powers, David N. Wiley, Anna R. Robuck, Zachary H. Olson, Linda J. Welch, Michael A. Thompson, Les Kaufman

Marine Ornithology

Movements of Great Shearwaters Ardenna gravis wintering in the Northwest Atlantic showed age-based spatial and temporal flexibility, with foraging tactics linked to a defined physical preference of their primary prey. From 2013 to 2018, we tracked 58 Great Shearwaters during their wintering season using platform terminal transmitters deployed in the same area of the southwest Gulf of Maine. Utilization distributions (UDs) for individual birds were created from convex hulls, which were then combined for spatial and temporal analyses. Of the 95% kernel UDs, 55% were contained within the Gulf of Maine and the remainder extended to the Scotian Shelf off …

Behavioral Responses To A Novel Feeding Problem In The Olrog's Gull Larus Atlanticus, Melina V. Castano, Laura M. Biondi, Francisco Zumpano, Marco Favero, Germán O. García

Marine Ornithology

Behavioral innovation is considered an expression of behavioral flexibility and is a source of phenotypic plasticity in animals. In this study, we explored the main components of behavioral innovation (neophobia and exploratory behavior) with respect to social context and age in the Olrog’s Gull Larus atlanticus. Twenty consecutive experimental sessions were performed, involving presentation of a plexiglass box containing food; the box could be opened and reached by pushing or pulling different lids, each leading to a food reward. Gulls were able to decrease their neophobic response throughout the course of the experiments. Fifty-three percent of individuals who entered the …
