Published: January 2021

AbstractOur everyday lives are increasingly pervaded by digital assistants and smart devices forming the Internet of Things (IoT). While user interfaces to directly monitor and control individual IoT devices are becoming more sophisticated and end-user friendly, applications to connect standalone IoT devices and create more complexIoT processesfor automating and assisting users with repetitive tasks still require a high level of technical expertise and programming knowledge. Related approaches for process modelling in IoT mostly suggest extensions to complex modelling languages, require high levels of abstraction and technical knowledge, and rely on unintuitive tools. We present a novel approach for end-user oriented-no-code-IoT process modelling using Mixed Reality (MR) technology:HoloFlows. Users are able to explore the IoT environment and model processes among sensors and actuators as first-class citizens by simply “drawing” virtual wires among physical IoT devices. MR technology hereby facilitates the understanding of the physical contexts and relations among the IoT devices and provides a new and more intuitive way of modelling IoT processes. The results of a user study comparing HoloFlows with classical modelling approaches show an increased user experience and decrease in required modelling knowledge and technical expertise to create IoT processes.
Quaker Business Ethics as MacIntyrean Tradition
Authors: Burton Nicholas , Sinnicks Matthew 
Published: January 2021

AbstractThis paper argues that Quaker business ethics can be understood as a MacIntyrean tradition. To do so, it draws on three key MacIntyrean concepts: community, compartmentalisation, and the critique of management. The emphasis in Quaker business ethics on finding unity, as well as the emphasis that Quaker businesses have placed on serving their local areas, accords with MacIntyre’s claim that small-scale community is essential to human flourishing. The emphasis on integrity in Quaker business ethics means practitioners are well-placed to resist the compartmentalising pressures of contemporary work. Quaker business ethics is also highly critical of the manipulative forms of management that MacIntyre regards as dominant. As such, Quaker business ethics provides evidence that more morally ameliorative forms of running business organisations is possible, even if they remain difficult to achieve.

Abstract
Background
Angiography derived FFR reveals good performance in assessing intermediate coronary stenosis. However, its performance under contemporary low X-ray frame and pulse rate settings is unknown. We aim to validate the feasibility and performance of quantitative flow ratio (QFR) and vessel fractional flow reserve (vFFR) under such angiograms.

Methods
This was an observational, retrospective, single center cohort study. 134 vessels in 102 patients, with angiograms acquired under 7.5fps and 7pps mode, were enrolled. QFR (fQFR and cQFR) and vFFR were validated with FFR as the gold standard. A conventional manual and a newly developed algorithmic exclusion method (M and A group) were both evaluated for identification of poor-quality angiograms.

Results
Good agreement between QFR/vFFR and FFR were observed in both M and A group, except for vFFR in the M group. The correlation coefficients between fQFR/cQFR/vFFR and FFR were 0.6242, 0.5888, 0.4089 in the M group, with rvFFR significantly lower than rfQFR (p = 0.0303), and 0.7055, 0.6793, 0.5664 in the A group, respectively. AUCs of detecting lesions with FFR ≤ 0.80 were 0.852 (95% CI 0.722–0.913), 0.858 (95% CI 0.778–0.917), 0.682 (95% CI 0.586–0.768), for fQFR/cQFR/vFFR in the M group, while vFFR performed poorer than fQFR (p = 0.0063) and cQFR (p = 0.0054). AUCs were 0.898 (95% CI 0.811–0.945), 0.892 (95% CI 0.803–0.949), 0.843 (95% CI 0.746–0.914) for fQFR/cQFR/vFFR in the A group. AUCvFFR was significantly higher in the A group than that in the M group (p = 0.0399).

Conclusions
QFR/vFFR assessment is feasible under 7.5fps and 7pps angiography, where cQFR showed no advantage compared to fQFR. Our newly developed algorithmic exclusion method could be a better method of selecting angiograms with adequate quality for angiography derived FFR assessment.

Published: January 2021

AbstractPolymer coatings on cellulosic fibres are widely used to enhance the natural fibre properties by improving, for example, the hydrophobicity and wet strength. Here, we investigate the effects of a terpolymer P(S-co-MABP-co-PyMA) coating on cotton linters and eucalyptus fibres to improve the resistance of cellulose fibres against wetness. Coated and uncoated fibres were characterised by using scanning electron microscopy, contact angle measurements, Raman spectroscopy and atomic force microscopy with the objective of correlating macroscopic properties such as the hydrophobicity of the fleece with microscopic properties such as the coating distribution and local nanomechanics. The scanning electron and fluorescence microscopy results revealed the distribution of the coating on the paper fleeces and fibres. Contact angle measurements proved the hydrophobic character of the coated fleece, which was also confirmed by Raman spectroscopy measurements that investigated the water uptake in single fibres. The water uptake also induced a change in the local mechanical properties, as measured by atomic force microscopy. These results verify the basic functionality of the hydrophobic coating on fibres and paper fleeces but call into question the homogeneity of the coating.Graphic abstract
Long-Term Mental Health and Quality of Life Outcomes of Neonatal Insults in Kilifi, Kenya

Published: January 2021

AbstractWe examined the mental health and quality of life (QoL) outcomes and their correlates of school-aged survivors of neonatal jaundice (NNJ), hypoxic-ischemic encephalopathy (HIE), and a comparison group. The Child Behavior Checklist and the Pediatric Quality of Life Inventory were administered to assess the mental health and QoL of 375 children (134 with NNJ, 107 with HIE, and 134 comparison group) aged 6 to 12 years [Median age 9 (interquartile range 7 to 11)]. The results showed that survivors of NNJ and HIE have mental health problems and QoL similar to the comparison group. Maternal mental health was the predominant covariate of mental health and QoL in survivors of NNJ and HIE. This result could indicate that mothers with mental health problems are more likely to have children with mental health issues, but also that caring for children with these adversities may affect mental health well-being of the caregivers. There is a need for early mental health screening and psychosocial intervention for caregivers and their children to enhance both their mental health and QoL.
A model of architecture for estimating GPU processing performance and power
Authors: Payvar Saman , Pelcat Maxime , Hämäläinen Timo D. 
Published: January 2021

AbstractEfficient usage of heterogeneous computing architectures requires distribution of the workload on available processing elements. Traditionally, the mapping is based on information acquired from application profiling and utilized in architecture exploration. To reduce the amount of manual work required, statistical application modeling and architecture modeling can be combined with exploration heuristics. While the application modeling side of the problem has been studied extensively, architecture modeling has received less attention. Linear System Level Architecture (LSLA) is a Model of Architecture that aims at separating the architectural concerns from algorithmic ones when predicting performance. This work builds on the LSLA model and introduces non-linear semantics, specifically to support GPU performance and power modeling, by modeling also the degree of parallelism. The model is evaluated with three signal processing applications with various workload distributions on a desktop GPU and mobile GPU. The measured average fidelity of the new model is 93% for performance, and 84% for power, which can fit design space exploration purposes.

AbstractThe results of field, analytical, and experimental research at a number of production facilities reflect the properties of oil-contaminated soils in 3 landscapes: the permafrost treeless Arctic ecosystem, boreal forest, and temperate-climate grassland-woodland ecotone. Laboratory studies have revealed the concentrations of petroleum hydrocarbons in soils, ranging from medium levels of 2000–3000 mg/kg to critical figures over 5000 mg/kg, being 2–25 times higher than the permissible content of oil products in soils. The experimentally applied thermal effects for the oil products desorption from the soil allowed finding an optimal regime: the treatment temperature from 25 to 250 °C reduces the concentrations to an acceptable value. The conditions are environmentally sound, given that the complete combustion point of humates is ca. 450 °C. The outcomes suggest the eco-friendly solution for soil remediation, preserving the soil fertility in fragile cold environments and in more resilient temperate climates, where revitalized brownfields are essential for food production.
The ethics of inattention: revitalising civil inattention as a privacy-protecting mechanism in public spaces
Authors: Sharon Tamar , Koops Bert-Jaap 
Published: January 2021

AbstractSocieties evolve practices that reflect social norms of appropriateness in social interaction, for example when and to what extent one should respect the boundaries of another person’s private sphere. One such practice is what the sociologist Erving Goffman called civil inattention—the social norm of showing a proper amount of indifference to others—which functions as an almost unnoticed yet highly potent privacy-preserving mechanism. These practices can be disrupted by technologies that afford new forms of intrusions. In this paper, we show how new networked technologies, such as facial recognition (FR), challenge our ability to practice civil inattention. We argue for the need to revitalise, in academic and policy debates, the role of civil inattention and related practices in regulating behaviour in public space. Our analysis highlights the relational nature of privacy and the importance of social norms in accomplishing and preserving it. While our analysis goes some way in supporting current calls to ban FR technology, we also suggest that, pending a ban and in light of the power of norms to limit what is otherwise technically possible, cultivating new practices of civil inattention may help address the challenges raised by FR and other forms of digital surveillance in public.

AbstractAdaptive time stepping methods for metastable dynamics of the Allen–Cahn and Cahn–Hilliard equations are investigated in the spatially continuous, semi-discrete setting. We analyse the performance of a number of first and second order methods, formally predicting step sizes required to satisfy specified local truncation error $$\sigma $$

during meta-stable dynamics. The formal predictions are made under stability assumptions that include the preservation of the asymptotic structure of the diffuse interface, a concept we call profile fidelity. In this setting, definite statements about the relative behaviour of time stepping methods can be made. Some methods, including all so-called energy stable methods but also some fully implicit methods, require asymptotically more time steps than others. The formal analysis is confirmed in computational studies. We observe that some provably energy stable methods popular in the literature perform worse than some more standard schemes. We show further that when Backward Euler is applied to meta-stable Allen–Cahn dynamics, the energy decay and profile fidelity properties for these discretizations are preserved for much larger time steps than previous analysis would suggest. The results are established asymptotically for general interfaces, with a rigorous proof for radial interfaces. It is shown analytically and computationally that for most reaction terms, Eyre type time stepping performs asymptotically worse due to loss of profile fidelity.

AbstractSol–gel formulations were applied to replace silicone as matrix material for phosphors in pc-LEDs. The content of organic groups was minimized in order to reduce yellowing during the operation of the elements. It was possible to evenly embed YAG:Ce particles in sol–gel binders. Further processing on LED chips resulted in operational light sources; and their performance was compared to standard silicone-based elements. Additional deposition of ALD laminates seals possible defects within the sol–gel matrix as additional protection of the phosphors and the underlying LEDs.
A simple metric of landscape fire exposure
Authors: Beverly Jennifer L. , McLoughlin Neal , Chapman Elizabeth 
Published: January 2021

AbstractContextProximity of landcover elements to each other will enable or constrain fire spread. Assessments of potential fire propagation across landscapes typically involve empirical or simulation models that estimate probabilities based on complex interactions among biotic and abiotic controls.ObjectivesWe developed a metric of landscape fire exposure based solely on a grid cell’s proximity to nearby hazardous fuel capable of transmitting fire to its location. To evaluate accuracy of this new metric, we asked:Do burned areas occur preferentially in locations with high exposure?MethodsWe mapped exposure to hazardous fuels in Alberta, Canada using a neighbourhood analysis. Correspondence between exposure and 2331 fires that burned 2,606,387 ha following our 2007 assessment was evaluated and exposure changes between 2007 and 2019 were assessed.ResultsIn all eleven ecological units analysed, burned area surpluses occurred where exposure was ≥ 60% and corresponding deficits occurred where exposure was < 40%. In seven ecological units, the majority of burned areas had pre-fire exposure ≥ 80%. Between 2007 and 2019, land area with exposure ≥ 80% increased by almost a third.ConclusionsExposure to hazardous fuels is easily quantified with a single thematic layer and aligns well with subsequent fires in Boreal, Foothills and Rocky Mountain natural regions. The resulting fire exposure metric is a numeric rating of the potential for fire transmission to a location given surrounding fuel composition and configuration, irrespective of weather or other fire controls. Exposure can be compared across geographic regions and time periods; and used in conjunction with other metrics of fire controls to inform the study of landscape fire.

Published: January 2021

AbstractContextAgricultural land use is expanding and is a major driver of the biodiversity crisis. Land use planning initiatives seeking to optimize wildlife conservation are hindered by a lack of baseline data quantifying species’ tolerance to human-modified landscapes.ObjectivesWe explored the influence of landscape characteristics on the fine-scale space-use patterns of a model generalist carnivore, the Malay civet (Viverra tangalunga), within degraded tropical forests and oil palm plantations.MethodsWe collected over 20,000 GPS locations from 21 male civets in Sabah, Malaysian Borneo to evaluate the species’ space-use patterns and habitat utilization processes. We used movement-based modeling to determine home ranges, and combined the results with high-resolution remotely sensed habitat characteristics. We developed resource utilization functions to determine individual and population-level functional responses to proximity to plantation edge, distance to water, terrain ruggedness, forest structure, and functional diversity.ResultsCivets foraged within oil palm plantations, yet all animals utilized forests. Home ranges scaled with proportion of plantation within both total and core ranges. Resource utilization functions reported individualism in the species’ responses to habitat characteristics. At the population-scale, civets consistently and more intensely used habitats closer to plantation edges and taller tree canopies.ConclusionsAlthough plantations did not pose an inhospitable matrix, oil palm agriculture is a less suitable habitat than remnant forests for civets. Proximity measures and forest structure influenced the spatial behaviors of this adaptable generalist, highlighting the importance of protected areas. We recommend land-sparing and -sharing approaches to facilitate carnivore persistence across oil palm degraded landscapes.
The design of learning spaces matters: perceived impact of the deskless school on learning and teaching
Authors: Reinius Hanna , Korhonen Tiina , Hakkarainen Kai 
Published: January 2021

AbstractThis exploratory case study examined the kinds of activity that a ‘deskless school” (i.e., flexible physical school spaces) engenders among pupils and teachers. We also considered the meaning and significance that pupils and teachers attach to various features of the school, as well as the associated action possibilities. The data were gathered in a new school in the Helsinki capital area that was architecturally designed to have flexible learning spaces (FLS) without traditional classrooms or desks for pupils in an attempt to encourage pedagogical renewal. The participants comprised 17 pupils in one second-grade class and their two teachers. The data were collected by participant observation (15 lessons over 3 weeks) and interviews with the teachers and groups of pupils. Those working in FLS engaged in collaborative learning and teaching activities. Pupils worked constantly in pairs or small groups and studied collaboratively. They also incorporated mobility into their own learning activities and developed agency by choosing how and where they would work. In particular, they appreciated being able to collaborate with their peers and freely choose where and how to study. Teachers approved of the school environment’s facilitation of collaborative learning and highlighted the importance of professional co-planning and other aspects of collaboration. Overall, the design of school environments matters at the pedagogical and professional level. With thoughtful planning, such design can support deeper collaboration among teachers and pupils, foster knowledge sharing, and even develop pupils’ agency. Although the learning space itself does not ensure change, it does enable new kinds of interaction and joint learning activities.
A ‘Life-Style Choice’ or a Philosophical Belief?: The Argument for Veganism and Vegetarianism to be a Protected Philosophical Belief and the Position in England and Wales
Authors: McKeown Paul , Dunn Rachel Ann 
Published: January 2021

AbstractThe recent judgment in Casamitjana Costa v The League Against Cruel Sports in England and Wales held that ethical veganism was a protected philosophical belief under employment law. In contrast, vegetarianism was found not to be a protected philosophical belief in Conisbee v Crossley Farms Limited and others. The authors argue that the Employment Tribunal misunderstood the notion of vegetarianism when deciding that it was a ‘life-style choice’. There are different kinds of vegans and vegetarians, each with their own way of practising the philosophy which influences how they live their life. Not all people who follow a meat-free diet should be afforded this protection, and it depends on whether their belief is one which is determined by certain factors, such as animal welfare and environmentalism, rather than for health purposes. The authors explore the arguments and analysis in the above employment cases, coming to the conclusion that the tribunals oversimplified what it means to hold values such as veganism and vegetarianism, failing to understand the differences between different classifications and sub-groups when coming to a decision. The different kinds of vegans and vegetarians and their characteristics are outlined, before determining whether this should constitute protection under employment law, protecting individuals from discrimination. The situation in the USA and Canada regarding this issue is very different, and there are parallels drawn with attempting to establish veganism or vegetarianism as a religion, and where they could benefit from the recent decision in England and Wales. Finally, this paper concludes that ethical and environmental veganism and vegetarianism should both qualify as protected philosophical beliefs, but other kinds may fall short of what is required to satisfy the requirements under law.
Illustrative Discussion of MC-Dropout in General Dataset: Uncertainty Estimation in Bitcoin
Authors: Alarab Ismail , Prakoonwit Simant , Nacer Mohamed Ikbal 
Published: January 2021

AbstractThe past few years have witnessed the resurgence of uncertainty estimation generally in neural networks. Providing uncertainty quantification besides the predictive probability is desirable to reflect the degree of belief in the model’s decision about a given input. Recently, Monte-Carlo dropout (MC-dropout) method has been introduced as a probabilistic approach based Bayesian approximation which is computationally efficient than Bayesian neural networks. MC-dropout has revealed promising results on image datasets regarding uncertainty quantification. However, this method has been subjected to criticism regarding the behaviour of MC-dropout and what type of uncertainty it actually captures. For this purpose, we aim to discuss the behaviour of MC-dropout on classification tasks using synthetic and real data. We empirically explain different cases of MC-dropout that reflects the relative merits of this method. Our main finding is that MC-dropout captures datapoints lying on the decision boundary between the opposed classes using synthetic data. On the other hand, we apply MC-dropout method on dataset derived from Bitcoin known as Elliptic data to highlight the outperformance of model with MC-dropout over standard model. A conclusion and possible future directions are proposed.
