Authors: Fernández‐Irisarri Itsaso , Mañas Manuel 
Published: May 2023

AbstractThe Cholesky factorization of the moment matrix is considered for discrete orthogonal polynomials of hypergeometric type. We derive the Laguerre–Freud equations when the first moments of the weights are given by the 1F2, 2F2, and 3F2 generalized hypergeometric series.

Published: May 2023

AbstractDigital terrain models (DTMs) are datasets containing altitude values above or below a reference level, such as a reference ellipsoid or a tidal datum over geographic space, often in the form of a regularly gridded raster. They can be used to calculate terrain attributes that describe the shape and characteristics of topographic surfaces. Calculating these terrain attributes often requires multiple software packages that can be expensive and specialized. We have created a free, open‐source R package, MultiscaleDTM, that allows for the calculation of members from each of the five major thematic groups of terrain attributes: slope, aspect, curvature, relative position, and roughness, from a regularly gridded DTM. Furthermore, these attributes can be calculated at multiple spatial scales of analysis, a key feature that is missing from many other packages. Here, we demonstrate the functionality of the package and provide a simulation exploring the relationship between slope and roughness. When roughness measures do not account for slope, these attributes exhibit a strong positive correlation. To minimize this correlation, we propose a new roughness measure called adjusted standard deviation. In most scenarios tested, this measure produced the lowest rank correlation with slope out of all the roughness measures tested. Lastly, the simulation shows that some existing roughness measures from the literature that are supposed to be independent of slope can actually exhibit a strong inverse relationship with the slope in some cases.

AbstractFeline oral squamous cell carcinoma (FOSCC) is an aggressive cancer in domestic cats that has no effective treatment option when advanced. Preventative or early diagnostic measures are thus crucial. FOSCC is also a model for human head and neck SCC (HNSCC); strong risk factors in HNSCC include exposure to alcohol, tobacco, areca nut, and high‐risk human papillomavirus. Previous studies have identified flea collar and tobacco smoke exposure, feeding canned tuna, canned cat food and cat foods with chemical additives, living in a rural environment, and having outdoor access as risk factors for FOSCC but there was no overlap in the risk factors between studies. In our study, risks for FOSCC were evaluated in an online epidemiologic survey study in 67 cats with FOSCC and 129 control cats. Clumping clay cat litter and flea collar use were significant risk factors for FOSCC on multiple logistic regression with odds ratios of 1.66 (95% CI 1.20–2.30) and 4.48 (95% CI 1.46–13.75) respectively. Crystalline silica is a carcinogen that may be present in all clay cat litters and tetrachlorvinphos is a carcinogen that is present in the most commonly used flea collars in our study. We recommend further investigation into the association between FOSCC and clay‐based litter and/or flea collars containing tetrachlorvinphos.

Published: May 2023

Abstract
Hydraulic actuation systems have a broad range of applications covering almost all areas of manufacturing and production and also the service industry. However, it is usual for systems to have low energy efficiency. In recent decades, due to global environmental concerns, research in the field of digital hydraulics to develop more efficient hydraulic systems has increased. In this paper, an analysis of the possible combinations of chambers in a multichamber cylinder is presented. A mathematical expression is derived to verify the total number of combinations of chambers that it is possible to achieve for a cylinder with four or more chambers and that result in different constant velocities without cavitation occurring. In addition, a digital hydraulic pump is considered a supply unit and, since it has discrete output flow rates, an analytical method to combine the pump with a multichamber cylinder is developed resulting in a total number of cylinder velocities with a required resolution. For application in a positioning system, design guidelines for an actuator using a cylinder with four chambers and a digital hydraulic pump with three fixed displacement units are presented in which an optimization algorithm for the calculation of the cylinder areas and the volumetric displacement of the pumps is applied. The proposed approaches were applied to design a proof-of-concept and the experimental values presented very good accuracy when compared with the results obtained with the model. Closed-loop position control responses show that the system can achieve the required setting time with a smooth movement and steady-state error of around 1 mm.

Seamless Parametrization with Cone and Partial Loop Control
Authors: Levi Zohar 
Published: May 2023

We present a method for constructing seamless parametrization for surfaces of any genus that can handle any feasible cone configuration with any type of cones. The mapping is guaranteed to be locally injective, which is due to careful construction of a simple domain boundary polygon. The polygon’s complexity depends on the cones in the field, and it is independent of mesh geometry. The result is a small polygon that can be optimized prior to the interior mapping, which contributes to the robustness of the pipeline.
For a surface of genus >0, non-contractible loops play an important role, and their holonomies significantly affect mapping quality. We enable holonomy prescription, where local injectivity is guaranteed. Our prescription, however, is limited and cannot handle all feasible holonomies due to monotonicity constraints that keep our polygon simple. Yet this work is an important step toward fully solving the holonomy prescription problem.
Virgilian Criticism and the Intertextual Aeneid
Authors: Giusti Elena 
Published: May 2023

Abstract
This review article of Joseph Farrell’s 2021 monograph on Virgil’s Aeneid (Juno’s Aeneid: A Battle for Heroic Identity, Princeton and Oxford) takes the cue from Farrell’s analysis of Virgil’s intertextuality with the Homeric epics and provides a methodological re-assessment of intertextuality in Virgilian studies and Latin literature more broadly. It attempts to retrace the theoretical history and some of the main applications of Latin intertextual studies and suggests some possible ways for Latinists to engage more profoundly with deconstructive criticism and post-critique.

Published: May 2023

Objectives: COVID-19 vaccines are widely available, but uptake is suboptimal. To develop strategies to increase vaccination rates, we sought to (1) characterize adults initially hesitant to be vaccinated for COVID-19 who later received the vaccine and (2) identify factors associated with their vaccination decision. Methods: In January 2021, we conducted an online survey of US adults via Prolific that assessed vaccination intent, COVID-19–related knowledge and attitudes, and demographic characteristics. In May 2021, we recontacted respondents to assess vaccination status and factors influencing their vaccination decision. We used χ2 statistics and t tests to examine associations between respondents’ vaccination status and their characteristics, knowledge, and attitudes. We analyzed reasons for vaccination using thematic analysis. Results: Of 756 initially vaccine-hesitant respondents, 529 (70.0%) completed the follow-up survey. Nearly half of those initially not sure about vaccination (47.3%, 112 of 237) were vaccinated at follow-up, while 21.2% (62 of 292) of those initially planning not to be vaccinated were vaccinated at follow-up. Of those initially not sure, higher educational attainment, greater knowledge of COVID-19, and a doctor’s recommendation were associated with vaccination. Of those initially intending not to be vaccinated, male sex, Democratic political affiliation, receipt of an influenza shot within 5 years, being more worried about COVID-19, and having greater COVID-19 knowledge were associated with increased likelihood of being vaccinated. Of 167 respondents who gave reasons for vaccination, protecting oneself and others (59.9%), practical issues (29.9%), social influences (17.4%), and vaccine safety (13.8%) were the main reasons. Conclusion: Providing information on the protective value of vaccination, implementing rules that make remaining unvaccinated burdensome, making vaccination easy, and providing social support may influence vaccine-hesitant adults to accept vaccination.
Bayesian Models with Spatial Correlation Improve the Precision of EQ-5D-5L Value Sets

Published: May 2023

Background Health utilities from value sets for the EQ-5D-5L are commonly used in economic evaluations. We examined whether modeling spatial correlation among health states could improve the precision of the value sets. Methods Using data from 7 EQ-5D-5L valuation studies, we compared the predictive precision of the published linear model, a recently proposed cross-attribute level effects (CALE) model, and 2 Bayesian models with spatial correlation. Predictive precision was quantified through the root mean squared error (RMSE) for out-of-sample predictions of state-level mean utilities on omitting individual states, as well as omitting blocks of states. Results In all 7 countries, on omitting single health states, Bayesian models with spatial correlation improved upon the published linear model: the RMSEs for the originally published models, 0.050, 0.051, 0.060, 0.061, 0.039, 0.050, and 0.087 for Canada, China, Germany, Indonesia, Japan, Korea, and the Netherlands, respectively, could be reduced to 0.043, 0.042, 0.051, 0.054, 0.037, 0.037, and 0.085, respectively. On omitting blocks of health states, Bayesian models with spatial correlation led to smaller RMSEs in 3 countries, while the CALE model led to smaller RMSEs in the remaining 4 countries. Discussion: Bayesian models incorporating spatial correlation and CALE models are promising for improving the precision of value sets for the EQ-5D-5L. The differential performance of the Bayesian models on omitting single states versus blocks of states suggests that designing valuation studies to capture more health states may further improve precision. We suggest that Bayesian and CALE models be considered as candidates when creating value sets and that alternative designs be explored; this is vital as the prediction errors in value sets need to be smaller than the minimal important difference of the instrument. Highlights The accuracy of value sets of multi-attribute utility instruments is typically of the same order of magnitude as the instrument’s minimal important difference and would benefit from improvement. Bayesian models with spatial correlation have been shown to improve value set accuracy in isolated cases. We showed that Bayesian approaches with spatial correlation improved predictive precision in 7 EQ-5D-5L valuation studies. We recommend that Bayesian models incorporating spatial correlation be considered when creating value sets and have provided code for fitting them.

Published: May 2023

Background Moral resilience is the integrity and emotional strength to remain buoyant and achieve moral growth amid distressing situations. Evidence is still emerging on how to best cultivate moral resilience. Few studies have examined the predictive relationship of workplace well-being and of organizational factors with moral resilience. Research aims The aims are to examine associations of workplace well-being (i.e., compassion satisfaction, burnout, and secondary traumatic stress) and moral resilience, and to examine associations of workplace factors (i.e., authentic leadership and perceived congruence of organizational mission and behaviors) and moral resilience. Research design This study uses a cross-sectional design. Participants and research context Nurses practicing in a hospital in the United States were surveyed using validated instruments (N = 147). Individual factors were measured using demographics and the Professional Quality of Life Scale. Organizational factors were measured using the Authentic Leadership Questionnaire and a single item measuring organizational mission/behavior congruence. Moral resilience was measured using the Rushton Moral Resilience Scale. Ethical considerations The study was approved by an institutional review board. Findings Resilience was noted to have significant small correlations with burnout, secondary traumatic stress, compassion satisfaction, and organizational mission/behavior congruence. Burnout and secondary traumatic stress predicted less resilience, whereas compassion satisfaction and perceived congruence between organizational mission and behaviors predicted higher resilience. Discussion Burnout and secondary traumatic stress, increasingly experienced by nurses and other health professionals, have negative effects on moral resilience. Compassion satisfaction can increase resilience, which is especially important in nursing. Organizational practices promoting integrity and confidence can have positive effects on resilience. Conclusions Continued work to confront workplace well-being issues, especially burnout, is needed as a way of increasing moral resilience. Studies of organizational and work environment factors to bolster resilience are likewise needed to assist organizational leaders in devising the best strategies.

Published: May 2023

BACKGROUND E-cigarette products have become more popular due to the marketing campaigns on various sources but caused adverse health impacts to users, especially adolescents and youths. This paper aims to describe the situation of exposure to e-cigarette advertisements of youth and adolescents living in two cities of Hanoi and Ho Chi Minh in 2020 and identify the associated factors of e-cigarette marketing with e-cigarettes use in these groups. METHODOLOGY This was a cross-sectional study. The study participants were 1211 youth and adolescents aged 15-24 living in Hanoi and Ho Chi Minh City during the time of data collection (from January 2020 to September 2020). Two primary outcome variables included the ever e-cigarettes use and the intention to use e-cigarettes. Multivariate logistic regression models were used to assess the association between the outcome variables and e-cigarette marketing exposure. RESULTS The proportion of participants who ever use e-cigarettes was 7.4% and a proportion of 4.8% have intention to use e-cigarettes. The most popular source of exposure to e-cigarettes advertisements was social network (Facebook, Twitter, Instagram, Youtube, etc.) and this source had positive association with the odds of e-cigarette smoking among youth and adolescents (OR = 3.38, 95% CI: 1.59-7.14). In addition, referral marketers also contributed to making the participants more likely to smoke e-cigarettes (OR = 2.68, 95% CI: 1.03-6.95). Attractive color and free sample of e-cigarettes were also found to be the motivated factors associated with smoking behaviour among youth and adolescents. CONCLUSIONS New policies should be considered to oppose the impact of youth-oriented e-cigarette advertisements which include regulating and restricting e-cigarette advertisements on social media, as well as through referral marketers.

Published: May 2023

In the wake of COVID-19, the American College of Lifestyle Medicine offered its members an online 10-week multicomponent mental health and wellbeing program (The Lift Project), and extended the invitation to members from sister organizations associated with the Lifestyle Medicine Global Alliance. A total of 1785 members registered for the program, representing 39 countries. The website hosting the program recorded 9815 total visits over the 10 weeks. In a post-program questionnaire completed by 145 participants, 91% agreed or strongly agreed that the program supported their mental wellbeing, and participants reported their wellbeing as higher after the program as compared to its commencement (X2 = 80.8, P < .01). Ninety-four percent of respondents indicated they would recommend the program to a friend. Thematic analysis of open-ended responses included in the post-program evaluation indicated that the participants liked: the structure of the program and content covered; the style of the video presentations; and the practical application of the program. Some participants indicated they would have liked more time to engage with the program and would have enjoyed the provision of group meetings. In conclusion, healthcare organizations can support their members’ mental health and wellbeing by offering large-scale, evidence-based interventions.

Published: May 2023

Background/Aims This article discusses the barriers that prevent deaf people from participating in clinical trials and offers recommendations to overcome these barriers and ensure equal access to study participation. Methods Between April and May 2022, we conducted six focus groups with 20 deaf adults who use American Sign Language, all of whom had previous experience as research study participants. Focus group prompts queried community awareness of clinical trial opportunities, barriers and facilitators to deaf people’s participation in clinical trials, and recommended resources to improve clinical trial access. This qualitative focus group data is supplemented by survey data gathered from 40 principal investigators and clinical research coordinators between November 2021 and December 2021. The survey queried researchers’ prior experiences with enrolling deaf participants in clinical trials and strategies they endorse for enrollment of deaf participants in future clinical trials. Results Focus group participants unanimously agreed that, compared to the general hearing population, deaf sign language users lack equivalent access to clinical trial participation. Reported barriers included lack of awareness of clinical trial opportunities, mistrust of hearing researchers, and refusal by clinical trial staff to provide accessible communication (e.g. denial of requests for sign language interpreters). Survey data from 40 principal investigators and clinical research coordinators corroborated these barriers. For example, only 2 out of 40 survey respondents had ever enrolled a deaf person in a clinical trial. Respondents indicated that the most helpful strategies for including deaf sign language users in future clinical trials would be assistance with making recruitment information accessible to deaf sign language users and assistance in identifying qualified interpreters to hire to help facilitate the informed consent process. Conclusion The lack of communication accessibility is the most common factor preventing deaf sign language users from participating in clinical trials. This article provides recommendations for hearing researchers to improve deaf people’s access to clinical trials moving forward, drawing from mixed-methods data.
