AbstractLiterature on the air travel activities of patients supported by permanent mechanical assist devices is rare. To the best of our knowledge, no air travel guidelines or fitness prerequisites exist on whether and when ventricular assist device (VAD) patients are allowed to travel by plane after device implantation. In this study, we evaluated the topic of air travel after VAD implantation. This working group aimed to produce a report on air travel passengers supported by VADs, regarding their fitness to fly. Fifty left ventricular assist device (LVAD) patients were surveyed in a worldwide multicenter study. The single survey was performed with a multimethod design, including interviews conducted face‐to‐face, online, and on phone. Out of 50 patients, 97% described their traveling by aircraft as perfect and uneventful during the flight. Eighty‐five percent of the study participants consulted their medical practitioner before the flight. No patient reported the occurrence of a severe condition associated with flying. LVAD alarms, especially low flow alarms, did not occur in any of the devices. Thirty‐five percent of the surveyed patients, however, stated a major problem pertaining to the security check procedures at the airport. The results of this study suggest that commercial air travel is safe for stable patients on permanent VAD support and traveling can be resumed securely after VAD implantation. Conscientious preparation by packing necessary devices, fluids, medications, and careful preparation for the airport security check is recommended.

AbstractPurposeTo explore the changes over time and regional differences in the incidence of retinopathy of prematurity (ROP) in a national cohort of infants born <28 weeks' gestational age (GA).MethodsA population‐based study of infants with GA <28 weeks in Norway from 2009 to 2017. Prospectively collected data on clinical variables and outcomes were obtained from the Norwegian Neonatal Network.ResultsOf 1499 live‐born infants transferred to a neonatal intensive care unit, 1156 were discharged alive. Four‐hundred and fifty‐eight infants (39.6%) had ROP, 152 (13.1%) had severe ROP, and 110 (9.5%) were treated for ROP. Eleven hundred infants (95.2%) had complete data sets. In a model comprising region of primary care, GA [odds ratios (OR): 0.65; 95% CI: 0.55–0.77], growth velocity (OR: 1.10; 95% CI: 1.00–2.00), medically treated patent ductus arteriosus (OR: 1.80; 95% CI: 1.19–2.72), weeks of supplemental oxygen (OR: 1.07; 95% CI: 1.03 to 1.11) and region of primary care (OR: 4.95; 95% CI: 3.05–8.04 for the pair of regions with the highest estimated OR) were significantly associated with severe ROP. Additionally, institutional differences for severe ROP were found, with ORs from 0.41 (95% CI: 0.05–3.23) to 5.36 (95% CI: 3.05–9.43) using the largest institution as reference. Incidences were stable over time after adjusting for GA. A larger proportion was treated with anti‐vascular endothelial growth factor after 2011.ConclusionsThe incidence of severe ROP was stable between 2009 and 2017 in Norway. Regional and institutional differences need to be explored in future studies.

AbstractQuestionsLight availability at the forest floor affects many forest ecosystem processes, and is often quantified indirectly through easy‐to‐measure stand characteristics. We investigated how three such characteristics, basal area, canopy cover and canopy closure, were related to each other in structurally complex mixed forests. We also asked how well they can predict the light‐demand signature of the forest understorey (estimated as the mean Ellenberg indicator value for light [“EIVLIGHT”] and the proportion of “forest specialists” [“%FS”] within the plots). Furthermore, we asked whether accounting for the shade‐casting ability of individual canopy species could improve predictions of EIVLIGHT and %FS.LocationA total of 192 study plots from nineteen temperate forest regions across Europe.MethodsIn each plot, we measured stand basal area (all stems >7.5 cm diameter), canopy closure (with a densiometer) and visually estimated the percentage cover of all plant species in the herb (<1 m), shrub (1–7 m) and tree layer (>7 m). We used linear mixed‐effect models to assess the relationships between basal area, canopy cover and canopy closure. We performed model comparisons, based on R2 and the Akaike Information Criterion (AIC), to assess which stand characteristics can predict EIVLIGHT and %FS best, and to assess whether canopy shade‐casting ability can significantly improve model fit.ResultsCanopy closure and cover were weakly related to each other, but showed no relation with basal area. For both EIVLIGHT and %FS, canopy cover was the best predictor. Including the share of high‐shade‐casting species in both the basal‐area and cover models improved the model fit for EIVLIGHT, but not for %FS.ConclusionsThe typically expected relationships between basal area, canopy cover and canopy closure were weak or even absent in structurally complex mixed forests. In these forests, easy‐to‐measure structural canopy characteristics were poor predictors of the understorey light‐demand signature, but accounting for compositional characteristics could improve predictions.

AbstractThe diagnostic features of otolith morphology were provided for the clupeid fishes of the Iranian brackish and marine resources to be used as diagnostic features for the identification of clupeids diversity in these regions. Fish individuals belong to 20 species belong to 13 genera, and four families were collected from the Caspian Sea, the Persian Gulf and the Makran zone of the Oman Sea. Overall, seven otolith morphotypes were distinguished, that is lanceolated (45%), fusiform (20%), boot‐like (15%) and clamp‐like, pentagonal, elliptic and rectangular (each 5%, respectively). The univariate analysis showed that all variables except shape index [sulcus area (SS)/otolith area (OS)] and ROx (roundness) were significantly different among the clupeid species. The interspecific relationships of the otoliths were analysed based on the data of otolith morphology and otolith shape indices. Both dendrograms showed somehow an obvious separation among the studied species. However, the interspecific relationships in the dendrogram based on the otolith morphology have a better resolution. These phenotypic relationships based on otolith morphology among the studied clupeids are largely consistent with the previous hypothesis on the systematics of these fishes and emphasized that the morphological and morphometric features of the otolith, which are highlighted in this study, could be adequately used as diagnostic features for the identification of clupeids diversity.
Nonparametric cluster significance testing with reference to a unimodal null distribution
Authors: Helgeson Erika S. , Vock David M. , Bair Eric 
Published: September 2020

AbstractCluster analysis is an unsupervised learning strategy that is exceptionally useful for identifying homogeneous subgroups of observations in data sets of unknown structure. However, it is challenging to determine if the identified clusters represent truly distinct subgroups rather than noise. Existing approaches for addressing this problem tend to define clusters based on distributional assumptions, ignore the inherent correlation structure in the data, or are not suited for high‐dimension low‐sample size (HDLSS) settings. In this paper, we propose a novel method to evaluate the significance of identified clusters by comparing the explained variation due to the clustering from the original data to that produced by clustering a unimodal reference distribution that preserves the covariance structure in the data. The reference distribution is generated using kernel density estimation, and thus, does not require that the data follow a particular distribution. By utilizing sparse covariance estimation, the method is adapted for the HDLSS setting. The approach can be used to test the null hypothesis that the data cannot be partitioned into clusters and to determine the optimal number of clusters. Simulation examples, theoretical evaluations, and applications to temporomandibular disorder research and cancer microarray data illustrate the utility of the proposed method.

AbstractPatients with an ABL‐class fusion have a high risk of relapse on standard chemotherapy but are sensitive to tyrosine kinase inhibitors (TKI). In UKALL2011, we screened patients with post‐induction MRD ≥1% and positive patients (12%) received adjuvant TKI. As the intervention started during UKALL2011, not all eligible patients were screened prospectively. Retrospective screening of eligible patients allowed the outcome of equivalent ABL‐class patients who did and did not receive a TKI in first remission to be compared. ABL‐class patients who received a TKI in first remission had a reduced risk of relapse/refractory disease: 0% vs. 63% at four years (P = 0·009).

Published: September 2020

AbstractBackgroundComplex feeding difficulties requiring enteral (tube) feeding affect everyone around the child. Parents experience additional stress and are at risk of social isolation. This study investigated the strategies families develop and use to adjust and adapt to enteral feeding so they were not just surviving but thriving as a family.MethodsTwenty parents whose children had been or continued to be enterally fed were interviewed, four of them twice as their experience of enteral feeding progressed. Learning theory was used to conceptualize findings in terms of changing use of tools that mediated parents' response to feeding‐related challenges.ResultsParents encountered dilemmas relating to enteral feeding: maintaining participation in everyday activities, managing responses to the use of tubes for feeding, and doing what feels right for their child. They used four kinds of mediating tools to overcome these: memory aids and readiness tools, metaphors and narratives, repurposed everyday objects and personalized routines and materialities.ConclusionsThis novel account of tool used to resolve dilemmas provides an empirically and theoretically grounded basis for supporting parents to thrive despite the challenges of enteral feeding. Specifically, it can guide information given to help parents anticipate and cope with dilemmas arising from enteral feeding.

AbstractBackgroundLong‐term data (>10 years) concerning the survival and success rates of implants and implant‐supported prostheses are scarce.PurposeThe present investigation represents one of the first studies on dental implants covering an observational period of 25 years.Materials and methodsThis study presents the results obtained in 26 patients with 75 implants who participated over a 23‐ to 28‐year period in a supportive implant therapy (SIT) program at a private dental practice. We extracted existing data from the patients' files (pocket depths [PDs], bleeding on probing [BoP], radiographic peri‐implant bone loss, and survival rates of the implant‐supported prostheses).ResultsAfter 25 years, the SIT‐compliant patients' implants had a survival rate of 95% (prostheses: 88%). The mean peri‐implant probing depth was 3.69 mm (median: 3.33; SD: 1.06; range: 2‐8.33). The mean peri‐implant bone level was 1.84 mm (median: 1.82; SD: 1.20; range: −0.97‐5.2). Finally, the prevalence (moment of last consultation) and incidence (during the entire observational period) of peri‐implantitis were 7% and 30%, respectively.ConclusionsUnder SIT conditions, clinicians may expect survival rates for implant‐supported prostheses of >80%. Most implants (60%) did not develop signs of peri‐implantitis over a 25‐year period.
Improved fuzzy‐assisted hierarchical neural network system for design of computer‐aided English teaching system
Authors: Li Hui 
Published: September 2020

AbstractThe world has enhanced the development of education with the rapid development of information technology in modern society to facilitate the information process. Educational technology has gained experience through the advancement of digital information network technology, from modern teaching technology to computer technology and communication technology. In this paper, an English learning system has been developed based on an improved fuzzy‐assisted hierarchical neural network system (IF‐HNNS). Improving the standard of English education is particularly important in improving intelligent education, especially the efficiency of classroom teaching. The development of an interactive educational system has changed the conventional way of teaching and facilitated individual independent learning. This English teaching system is a network updating computer‐aided learning platform. The computer‐aided system has the following advantages: (i) Easy‐to‐actualize computer‐aided learning media will provide more teaching content and teach satisfaction. (ii) The interaction of computer‐aided learning will raise interest in learning. (iii) Computer helped learners are rich in educational resources and are easy to set teaching goals. (iv) It will improve the monitoring of the education and teaching cycle using a computer‐aided learning with human‐computer interaction method.
“Taking action for the Reef?”–Australians do not connect Reef conservation with individual climate‐related actions
Authors: Dean Angela J. , Gulliver Robyn E. , Wilson Kerrie A. 
Published: September 2020

AbstractClimate change is the most significant threat to the Great Barrier Reef (GBR). While Australians express appreciation and concern for the GBR, it is not clear whether they connect climate‐related action with reef conservation. An online survey of 4,285 Australians asked “…what types of actions could people like you do that would be helpful for the GBR?” Only 4.1% mentioned a specific action related to mitigating climate change; another 3.8% mentioned climate change but no specific action. The most common responses related to reducing plastic pollution (25.6%). These findings demonstrate that most Australians have poor capacity to identify individual climate‐related actions as helpful for reef protection, and that generic calls to action—such as “protect the reef”—are unlikely to elicit climate‐related actions. As such, reef conservation initiatives must explicitly promote actions—in the home and in society—that reduce emissions and support the transition to a low carbon society.

Published: September 2020

ABSTRACTBackgroundIt isn’t clear how lay people balance the various ethical interests when addressing medical issues. We explored lay people’s ethical resolution models in relation to abortion.MethodsIn a tertiary healthcare setting, 196 respondents rank‐ordered 42 opinion‐statements on abortion following a 9‐category symmetrical distribution. Statements’ scores were analyzed by averaging‐analysis and Q‐methodology.ResultsRespondents’ mean (SD) age was 34.5(10.5) years, 53% were women, 68% Muslims (31% Christians), 28% Saudis (26% Filipinos), and 38% healthcare‐related. The most‐agreeable statements were “Acceptable if health‐benefit to woman large,” “Acceptable if congenital disease risk large,” and “Woman’s right if fetus has congenital disease.” The most‐disagreeable statements were “State’s right even if woman disagrees,” “Acceptable even with no congenital disease risk,” and “Father’s right even if woman disagrees.” Q‐methodology identified several resolution models that were multi‐principled, consequentialism‐dominated, and associated with respondents’ demographics. The majority of Christian women and men identified with and supported a relatively “fetus rights plus State authority‐oriented” model. The majority of Muslim women and men identified with and supported a “conception‐oriented” model and “consequentialism plus virtue‐oriented” model, respectively. One or more of three motives‐related statements received extreme ranks on averaging‐analysis and in 33% of the models.Conclusions1) On average, consequentialism, focusing on a woman’s health‐benefit and congenital disease risk, was the predominant approach. This was followed by the rights approach, favoring a woman’s interest but taking context into account. 2) Q‐methodology identified various ethical resolution models that were multi‐principled and partially associated with respondents’ demographics. 3) Motives were important to some respondents, providing empirical evidence against adequacy of principlism.
Project‐Based Learning for Teaching Business Analytics in the Undergraduate Curriculum*
Authors: Yazici Hulya Julie 
Published: September 2020

ABSTRACTThe increasing use of massive data requires effective teaching strategies for business analytics. The discipline combines analytical skills, information technology, and business‐domain knowledge, and is challenging to teach to business students. This research demonstrates that business undergraduate students can benefit from an experiential project‐based learning approach (PjBL). By having student groups collecting data around a research question of their choosing and using descriptive and predictive analytics, we observed an increased understanding of the data‐driven decision‐making process, and improved analytical skills to approach, solve, and communicate business problems.

AbstractAimThe involvement of young people in the development, implementation and evaluation of youth mental health services, policy and research programs is essential to ensure they are appropriate and responsive to the needs of young people. Despite the increasingly central role that youth engagement and participation plays internationally, such activities are rarely described in detail. This article aims to provide a thorough description of the development and implementation of an organization‐wide, 3‐year Youth Engagement and Participation Strategy for Orygen, a national youth mental health organization in Australia.MethodsA descriptive account of the development and implementation of the Strategy, with detailed examples of programs and initiatives.ResultsThe Strategy was developed based on available evidence, focus groups with key stakeholders and best practice principles. The implementation of the Strategy resulted in a number of programs being delivered that involved a range of young people from across Australia. Despite being successful overall, a number of challenges were experienced. Ongoing considerations include ensuring diversity of partnerships, 'raising the bar' of youth participation and creating meaningful pathways.ConclusionsYouth participation and engagement within a youth mental health context is best seen as an evolving ambition that must remain flexible to the needs of all stakeholders. Despite some challenges and ongoing fine‐tuning, it is possible to successfully implement youth participation and engagement across all areas of youth mental health, including service design and delivery, research and translation, and policy.
The academic profession in North Macedonia: A never ending transition
Authors: Spasovski Ognen , Pecakovska Suzana 
Published: September 2020

AbstractThe context of Macedonian higher education has changed dramatically in the last fifteen years. A rapid increase in the number of public and private institutions and a greater diversity of higher education degrees have not been associated with improvements in quality. The research output of academic staff is modest; academics contribute little to the society's development. Academia in North Macedonia is under pressure due to chronic underfinancing of higher education and research, and an underdeveloped system of quality assurance, as well as growing expectations for relevance and internationalisation. This article presents an original empirical study on academic staff. It examines how 388 faculty at higher education institutions in North Macedonia perceived changes in the environment of the academic profession, and how changes in their working conditions potentially influence their academic identity and wellbeing. The results are compared to European data. Findings show that about half of research participants believed that the overall conditions for work and the quality of teaching, learning and research have deteriorated in recent years. This contributes to a perception of the academic profession as stressful and unattractive which results in lower levels of overall academic wellbeing which constitutes a threat to academic identity amongst the staff. Consequently, we expect further decreases in motivation, work ethic and productivity in the academic profession, as well as an increase in the desire of academics to leave Macedonia.
