A Study On The Effect Of Emotional Efforts Of Academicians In Tourism Departments On Job Stress, Hasan O. Seyhanlioglu, Sevki Ulema

Journal of Mediterranean Tourism Research

The aim of this study is to examine the emotional labor and job stress levels of tourism academicians who train sector managers. The t-test and One-Way ANOVA analysis were conducted to determine whether there is a difference between the quantitative data collected from 346 individuals working as academicians in tourism departments operating in Turkey and the demographic characteristics of the variables. In addition, explanatory factor analysis was performed for the emotional labor scale. As a result, it has been observed that the stress level is high in academicians who have just started their profession.

Fighting Words: Catalonia At The Language Instruction Crossroads, Jane Tien

Duke Journal of Comparative & International Law

The schism between Spain and Catalonia obscures a struggle over the teaching language for non-linguistic subjects in Catalonia's public schools. The recent two decades decanted into Catalan society two Spanish Constitutional Court rulings mandating a Castilian-Catalan conjunctive instruction model—with Catalan as the "center of gravity"—and tasking the Catalan legislature with configuring that "center." Pleasing none and spurned by all, the Constitutional Court duology emboldened activist lower courts to bypass the Catalan legislature, while schools in Catalonia continued to teach almost exclusively in Catalan. With the Castilians alienated and the Catalans defiant, language instruction in Catalonia turned into a festering wound …

Using Naming Conventions To Facilitate Data Transfer Between Asset Management Systems And Building Information Models, John D. Foster

Theses and Dissertations

An improvement to the workflow developed by Loeh et al. (2021) is proposed using a Revit template with BUILDER SMS naming conventions when creating the Sustainable Facility Management-enhanced BIM Model. The method presented by Loeh et al. (2021) is modified by integrating BUILDER SMS parameters and naming conventions into the BIM model during, as opposed to after, the creation of the model. Four building models created in 2020-21, four from 2021-22, and one building from 2019 were used in this study. Two groups of students were used to evaluate the effect of the building-specific BIM templates. Evaluating the 2020 and …

An Ad Hoc Dispute Settlement Mechanism Or A Harmonization Mission? A Reappraisal Of Jurisprudential Fragmentation In International Investment Arbitration, Mohammad Hamdy

Duke Journal of Comparative & International Law

Contrary to the numerous accounts of fragmentation in investment arbitration case law, this Article shows that the case law depicts a high degree of cohesion. The Article argues that jurisprudence in investment arbitration is stabilized by distinct mainstream interpretations of the key provisions of bilateral investment treaties, the main legal instrument in international investment law. The Article considers the frequently cited disagreements among arbitral tribunals in light of competing commitments to either regulatory pluralism or harmonization. It demonstrates that the vast majority of tribunals interpret bilateral investment treaties in a way that circumscribes pluralism and furthers the harmonization of the …

Factors Associated With Improved Outcome Of Inhaled Corticosteroid Use In Covid-19: A Single Institutional Study, A. Manfra, Claire Chen, Kavita Batra, Kyaw Min Tun, Mutsumi Kioka

Department of Internal Medicine Faculty Research

Asthmatics seem less prone to adverse outcomes in coronavirus disease 2019 (COVID-19) and some data shows that inhaled corticosteroids (ICS) are protective. We gathered data on anecdotal ICS and outcomes of patients hospitalized with COVID-19, given there is literature supporting ICS may reduce risk of severe infection. In addition, we fill gaps in current literature evaluating Charlson Comorbidity Index (CCI) as a risk assessment tool for COVID-19. This was a single-center, retrospective study designed and conducted to identify factors associated intubation and inpatient mortality. A multivariate logistic regression model was fit to generate adjusted odds ratios (OR). Intubation was associated …

Some Reflections On The “New Law Of The Sea”, Philippe Gautier

International Law Studies

The fortieth anniversary of the opening for signature of the UN Convention on the Law of the Sea provides an opportunity to offer some reflections on the “new law of the sea”; that is, the comprehensive set of rules that was the result of an unprecedented multilateral negotiation process: the Third United Nations Conference on the Law of the Sea (1973–1982). The focus of this article is on the adjudication of sea-related disputes in the “new law of the sea.” In an international legal order where access to a judge or an arbitrator requires the consent of both parties to …

Knowledge Mobilization For Agri-Food Supply Chain Decisions, Guoqing Zhao, Shaofeng Liu, Sebastian Elgueta, Juan Pablo Manzur, Carmen Lopez, Huilan Chen

Plymouth Business School

The current world business environment is characterized by increasing uncertainties, complexities, and risks, which require agri-food supply chain (AFSC) managers to respond and act quickly in a context full of instability and unpredictability. Increasing pressure placed on AFSC managers intensifies the need to combine knowledge management (KM) and decision support that rapidly overcome knowledge boundaries. It has been recognized that the research issue related to the knowledge mobilization crossing boundaries in the AFSC needs to be addressed. This paper investigates knowledge boundaries and boundary-spanning mechanisms by collecting data from experienced AFSC practitioners. Empirical results verify that knowledge boundaries such as …

The Effect Of Pre-Event Instructions On Eyewitness Identification, Jessica Allen

The Plymouth Student Scientist

Eyewitness identification research has informed policies and procedures, but experiments on eyewitness identification often use unrealistic testing methods. Part of these unrealistic methods are pre-event instructions given before the participant is exposed to the crime. Instructions can direct attention, thus lead to better accuracy. If previous research had used pre-event instructions, results may have overestimated people’s ability to identify culprits correctly and called into question the validity of previous conclusions. This would not be an issue if usage of pre-event instructions were reported in the literature, as comparisons could be made between studies that did use them or between studies …

Analysing Association Rates Of Reef Manta Rays (Mobula Alfredi) Situated In Chagos Archipelago, Lena Pollett

The Plymouth Student Scientist

Reef manta rays (Mobula alfredi) are in rapid decline and threatened by multiple anthropogenic pressures. Conservation of this vulnerable marine species requires an understanding of the drivers of their movement patterns and group structuring. Aggregations have been presumed to be a function of resource availability. However, recent studies have suggested that association rates within these areas of aggregation may underpin social behaviour, furthering our understanding of these species' movement and social networking. Here we used acoustic telemetry technology to assess the extent that a group of 26 M. alfredi associates within Egmont Atoll, situated within the Chagos Archipelagos, over a …

Computational Fluid Dynamics Optimisation Of Grid Fin Aerodynamic Design For Reusable Launch Vehicles, Jack Orders

The Plymouth Student Scientist

Grid fins are an unconventional flight control surface utilised by SpaceX for its Falcon 9 reusable launch vehicle upon re-entry. Previous literature surrounding grid fins has used computational fluid dynamics (CFD) to investigate sensitivity factors of the design to vary drag or maximise hinge moment but often suffer from limitations (e.g., insufficient modelling of the boundary layer, or no evidence of sensitivity studies/validation).Due to the lack of literature a systematic CFD-based method is employed in which grid fin geometry is simplified to a 2D flat plate and validated against Tekure (2021) and the simulation verified using oblique shock wave theory …

Biological Recruitment On Static And Boat Hull Panels Coated With Non-Toxic Fibre Flock, Julia Hinrichs

The Plymouth Student Scientist

Marine biofouling, the settlement of aquatic organisms on submerged surfaces, creates an estimated cost of 20 billion USD annually for the shipping industry in increased fuel consumption due to overgrowth. However, the existing antifouling solutions are being restricted by international organisations due to their adverse effects on the marine environment. In recent years, the research focus has shifted to non-toxic methods highlighting the importance of settlement cues of invertebrates. Biofoulers, such as invertebrate larvae and algal spores have been shown to respond to physical cues such as surface structure. The aim of this study was to test the environmentally friendly …

The Effect Of Seagrass Components On The Associated Bacterial Diversity And Antimicrobial Activity In Zostera Marina, Caroline Millan

The Plymouth Student Scientist

Seagrasses are marine angiosperms located in intertidal and sub-tidal waters. They are important ecosystem engineers that play a crucial role in the structure of habitats, allowing them to support a comprehensive diversity of life. Through fundamental ecological processes and the generation of niches, each seagrass species has aggregated an associated microbiome that lives among the various seagrass components and exhibit symbiotic relations. There have been studies investigating the diversity of the associated bacteria and elements of the resulting microbial activity, however these have primarily focused on tropical seagrass species and have failed to examine the extent of this bioactivity. This …

Age Differences In Facial First Impressions Of Traits Associated With Trustworthiness, Gulbeyaz Altun

The Plymouth Student Scientist

Older adults are more susceptible to becoming fraud victims due to increased generalised trust in others for assistance, leading to deception. Age differences in first impressions of unfamiliar faces on traits associated with trustworthiness was explored in this study. Investigating the various interpretations of trustworthiness across age has not been previously led. Using a data-driven approach, the key traits interpreted from trustworthiness were used in a trait rating task. Older adults provided higher ratings and showed an own-age bias for the traits trustworthy, honest, reliable, and loyal compared to younger adults, but not for the trait considerate. Mean trait ratings …

Investigating The Impacts Of Heterotrophic Nutrition On Acropora Microclados, Heather O'Keefe

The Plymouth Student Scientist

The Scleractinian coral Acropora microclados is a commercially important species that functions as both an autotroph and heterotroph. In ex situ coral aquaculture, elucidating an optimal diet to improve growth and resilience is critical in improving the sustainability and success of rearing corals for trade and conservation. To investigate the impacts of diet on A. microclados, three groups of 15 nubbins were kept under three different feeding regimes for three months at the National Marine Aquarium, Plymouth, UK. One group was fed nothing, the control (CTL), one group fed Artemia salina nauplii (ART) and one group fed a mixed diet …

Public Engagement In Environmental Issues: Investigating Factors Of Disengagement From An Individual And Organisational Perspective, Anna Carne

The Plymouth Student Scientist

Anthropogenic climate change is now a major issue facing the public, government, and environmental non-governmental organisations (ENGOs) alike. In order for climate goals set out by the conference of the parties (COP) summits to be reached, the public must be involved and feel a sense of responsibility to act. Though there have been previous studies investigating the levels of engagement and the actions that individuals take, the impact of certain factors on engagement is still not well understood. A UK survey open for two weeks and shared on social media was conducted. The survey consisted of open and closed questions …

An Investigation Into The Effects Of Weekly Habitual And Targeted Caffeine Consumption On Adult Runners' Endurance, Speed, And Mood, Elise Lucas

The Plymouth Student Scientist

BACKGROUND: Caffeine is a commonly consumed recreational drug which is also highly regarded as an ergogenic aid. Generally, users partake in sporadic and habitual caffeine consumption for functional benefits such as alertness or for social purposes, but targeted consumption prior to exercise is claimed to aid endurance, increase speed, and improve mood during exercise. OBJECTIVES: This questionnaire-based study aimed to evaluate the effect of targeted and randomised caffeine consumption on endurance, speed, and perceived mood in runners of varying levels. SUBJECTS: 489 subjects from 27 different countries (predominantly United States of America and United Kingdom) participated in the study (50.7% …

Marine Mammals In The Western English Channel, A Survey From The Rame Head Peninsula, Janine Douglas

The Plymouth Student Scientist

This paper presents the first records of marine mammals in Plymouth Sound National Marine Park (NMP), and over 1000 individual animal observations were recorded. Marine mammal temporal and spatial distributions were quantified for the first time at Rame Head, a vantage point overlooking the NMP and the Western English Channel. A biodiversity hotspot, the Western English Channel supports many species of marine mammals, yet it is subject to increasing anthropogenic pressures, such as heavy shipping, which could significantly impact populations. Whilst marine mammals are well studied, their distributions and population sizes remain largely unknown; effective conservation of these animals requires …

Sovereignty In The Era Of Fragmentation – Eu Trade Agreements And The Notion Of Statehood In International Law, Harri Kalimo, Shorena Nikoleishvili

Duke Journal of Comparative & International Law

In this article, we explore the theme of sovereignty in the context of fragmented international law. We observe that the sovereignty of States may become relativized, not only by the political power of other States, but by its exposure to multiple, functionally separate fields of law. We analyze this theme by asking whether trade agreements as instruments of economic law offer a venue for discussing the sovereignty of sub-statal entities that lack standing on the more traditional international forums. Our analysis focuses first on a recent decision by the Court of Justice of the European Union, which concerned the status …

Bankruptcy Basics: What The U.S. Can Learn From The U.K. Filing Processes, Courtney Kobren

Duke Journal of Comparative & International Law

Although filing for bankruptcy is the primary form of economic relief for U.S. consumers in financial distress, pro se debtors lack access to the consumer bankruptcy system. An individual debtor faces many challenges when filing for bankruptcy without an attorney, since the debtor must rely on free access to the information provided by the U.S. Courts website. However, that information is vague and presented in complex legalese and dissuasive diction. On the other hand, U.K. debtors who need financial relief can file for bankruptcy through a clear and accessible bankruptcy filing process. U.K. debtors also have access to free consumer …

Faculty, Staff and Student Publications

For patients suffering from myofascial pain syndrome (MPS) affecting muscles of mastication, traditional trigger point therapy treatment regimens can prove inconvenient, due to the short duration of pain relief after each injection and expense of repeated visits which are often not covered by insurance. We present a case of a patient treated using an alternative technique that could develop into an additional modality for treating MPS patients who are refractory to conservative treatment. This technique involves identifying and marking the patient's trigger points and surgically cauterizing each location using a Bovie electrosurgical unit. While traditional trigger point injection therapy for …

Emulating Future Neurotechnology Using Magic, Jay A. Olson, Mariève Cyr, Despina Z. Artenie, Thomas Strandberg, Lars Hall, Matthew L. Tompkins, Amir Raz, Petter Johansson

Psychology Faculty Articles and Research

Recent developments in neuroscience and artificial intelligence have allowed machines to decode mental processes with growing accuracy. Neuroethicists have speculated that perfecting these technologies may result in reactions ranging from an invasion of privacy to an increase in self-understanding. Yet, evaluating these predictions is difficult given that people are poor at forecasting their reactions. To address this, we developed a paradigm using elements of performance magic to emulate future neurotechnologies. We led 59 participants to believe that a (sham) neurotechnological machine could infer their preferences, detect their errors, and reveal their deep-seated attitudes. The machine gave participants randomly assigned positive …

Faculty, Staff and Student Publications

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a global pandemic. Angiotensin-converting enzyme 2 (ACE2) is an entry receptor for SARS-CoV-2. The full-length membrane form of ACE2 (memACE2) undergoes ectodomain shedding to generate a shed soluble form (solACE2) that mediates SARS-CoV-2 entry via receptor-mediated endocytosis. Currently, it is not known how the physiological regulation of ACE2 shedding contributes to the etiology of COVID-19 in vivo. The present study identifies Membrane-type 1 Matrix Metalloproteinase (MT1-MMP) as a critical host protease for solACE2-mediated SARS-CoV-2 infection. SARS-CoV-2 infection leads to increased activation of MT1-MMP that is colocalized with ACE2 in human lung …

Trends And Issues Involving Disabilities In Higher Education, Jm Kauffman, D Anastasiou, M Felder, J Lopes, Ba Hallenbeck, G Hornby, B Ahrbeck

More Faculty of Arts, Humanities and Business Research

People with disabilities have often been discriminated against in higher education; however, many institutions of higher education find ways of providing access to higher education for those with most forms of disabilities. Progress has been made in providing such access but undoubtedly there is still a need for more disability awareness, anti-stigma, and anti-discrimination training. At the same time higher education requirements, by default, involve higher cognitive capabilities. Some disabilities, those involving severe limitations of cognitive functioning, face insurmountable difficulties in meeting these higher intellectual demands, even with the most reasonable accommodations. Teacher education, for example, requires special attention to …
