The SARS‐CoV‐2 global pandemic will disproportionately impact countries with weak economies and vulnerable populations including people with dementia. Latin American and Caribbean countries (LACs) are burdened with unstable economic development, fragile health systems, massive economic disparities, and a high prevalence of dementia. Here, we underscore the selective impact of SARS‐CoV‐2 on dementia among LACs, the specific strain on health systems devoted to dementia, and the subsequent effect of increasing inequalities among those with dementia in the region. Implementation of best practices for mitigation and containment faces particularly steep challenges in LACs. Based upon our consideration of these issues, we urgently call for a coordinated action plan, including the development of inexpensive mass testing and multilevel regional coordination for dementia care and related actions. Brain health diplomacy should lead to a shared and escalated response across the region, coordinating leadership, and triangulation between governments and international multilateral networks.
Farm-Level Impacts of Greenhouse Gas Reductions for the Predominant Production Systems in Northern Nigeria
Authors: Ayinde Taiwo B. , Ahmed Benjamin , Nicholson Charles F.
Published: November 2020

This chapter summarizes the sources of greenhouse gas (GHG) emissions from different economic sectors in Nigeria and emphasizes those arising from agriculture and forestry. The impacts of climate change on agricultural systems in Nigeria are likely to be large, motivating the need for additional knowledge to assess current practices and formulate appropriate modifications for both mitigation and adaptation. Some current farming practices are believed to be adaptive, but further study would provide better assessments. We also analyzed the trade-offs between household income and GHG emissions at two contrasting sites in northern Nigeria. A farm optimization model maximizing the value of crop, livestock, and tree production activities in a single representative year assessed the potential impacts for GHG reductions of 10% and 25% and the maximum allowable reductions of 26% and 30% on farm activities and income. Emissions reductions of 10% reduced annual household incomes by less than 5% but required substantive changes, especially in livestock owned. Maximum possible GHG emissions reductions (while still meeting minimum household consumption needs) would require marked changes in production pattern and would lower household incomes by 22–44%. We did not assess effects over longer periods, where the role of livestock as a key asset may imply additional negative impacts. Productivity-enhancing technologies that would simultaneously reduce GHG emissions and increase incomes are needed for smallholder farms to play a larger role in climate change mitigation without the burden of reduced incomes and greater risk. This suggests the need for programmatic and policy actions both by national agricultural research systems and the Consultative Group for International Agricultural Research (CGIAR).
Greenhouse Gases Emissions in Agricultural Systems and Climate Change Effects in sub-Saharan Africa
Authors: Ntinyari Winnie , Gweyi-Onyango Joseph P.
Published: November 2020

Climate change has been viewed to result from anthropogenic human activities that have significantly altered the Nitrogen (N) cycle and carbon cycles, increasing the risks of global warming and pollution. A key cause of global warming is the increase in greenhouse gas emissions including methane, nitrous oxide, and carbon among others. The context of this chapter is based on a comprehensive desktop review on published scientific papers on climate change, greenhouse emissions, agricultural fertilizer use, modeling and projections of greenhouse gases emissions. Interestingly, sub-Saharan Africa (SSA) has the least emissions of the greenhouses gases accounting for only 7% of the total world’s emissions, implying that there is overall very little contribution yet it has the highest regional burden concerning climate change impacts. However, the values could be extremely higher than this due to lack of proper estimation and measurement tools in the region and therefore, caution needs to be taken early enough to avoid taking the trend currently experienced in developed nations. In SSA, agricultural production is the leading sector in emissions of N compound to the atmosphere followed by energy and transportation. The greatest challenge lies in the management of the two systems to ensure sufficiency in food production using more bioenergy hence less pollution. Integrating livestock and cropping systems is one strategy that can reduce methane emissions. Additionally, developing fertilizer use policy to improve management of fertilizer and organic manure have been potentially considered as effective in reducing the effects of agriculture activities on climate change and hence the main focus of the current chapter.
Surgical and embryological perspective of a big loop of internal carotid artery extending laterally beyond internal jugular vein
Authors: Nayak Satheesha B. , Shetty Surekha D.
Published: November 2020

Knowledge of variations of the internal carotid artery is significant to surgeons and radiologists. The internal carotid artery normally runs a straight course in the neck. Its anomalies can lead to its iatrogenic injuries. We report a case of a large loop of the internal carotid artery in a male cadaver aged about 75 years. The common carotid artery terminated by dividing it into the external carotid artery and internal carotid arteries at the level of the upper border of the thyroid cartilage. From the level of origin, the internal carotid artery coursed upwards, backwards and laterally, and formed a large loop behind the internal jugular vein. The variation was found on the left side of the neck and was unilateral. The uncommon looping of the internal carotid artery might result in altered blood flow to the brain and may lead to misperceptions in surgical, imaging, and invasive procedures.
Quantum-inspired learning vector quantizers for prototype-based classification
Authors: Villmann Thomas , Engelsberger Alexander , Ravichandran Jensun , Villmann Andrea , Kaden Marika
Published: November 2020

Prototype-based models like the Generalized Learning Vector Quantization (GLVQ) belong to the class of interpretable classifiers. Moreover, quantum-inspired methods get more and more into focus in machine learning due to its potential efficient computing. Further, its interesting mathematical perspectives offer new ideas for alternative learning scenarios. This paper proposes a quantum computing-inspired variant of the prototype-based GLVQ for classification learning. We start considering kernelized GLVQ with real- and complex-valued kernels and their respective feature mapping. Thereafter, we explain how quantum space ideas could be integrated into a GLVQ using quantum bit vector space in the quantum state space$${\mathcal {H}}^{n}$$Hnand show the relations to kernelized GLVQ. In particular, we explain the related feature mapping of data into the quantum state space$${\mathcal {H}}^{n}$$Hn. A key feature for this approach is that$${\mathcal {H}}^{n}$$Hnis an Hilbert space with particular inner product properties, which finally restrict the prototype adaptations to be unitary transformations. The resulting approach is denoted as Qu-GLVQ. We provide the mathematical framework and give exemplary numerical results.
Unearthing the entangled roots of urban agriculture
Authors: London Jonathan K. , Cutts Bethany B. , Schwarz Kirsten , Schmidt Li , Cadenasso Mary L.
Published: November 2020

This study examines urban agriculture (UA) in Sacramento, California (USA), the nation's self-branded “Farm-to-Fork Capital,” in order to highlight UA’s distinct yet entangled roots. The study is based on 24 interviews with a diverse array of UA leaders, conducted as part of a five-year transdisciplinary study of UA in Sacramento. In it, we unearth three primary “taproots” of UA projects, each with its own historical legacies, normative visions, and racial dynamics. In particular, we examine UA projects with “justice taproots,” “health taproots,” and “market taproots.” We use this analysis to understand how different kinds of UA projects are embedded in racial capitalism in ways that transform relationships between people, the city, and food systems. Unearthing these entangled roots helps illuminate UA’s underlying politics, showing how these roots grow in both competitive and symbiotic ways within the soil matrix of racial capitalism. We argue that these roots interact differently with racial capitalism, creating disparities in their growth trajectories. In particular, UA projects associated with the justice taproot are historically underrepresented and undervalued. However, we argue that there are some prospects for building alliances between the UA movement’s three roots, and that these are both promising and problematic.
Seismic reliability analysis of steel moment-resisting frames retrofitted by vertical link elements using combined series–parallel system approach
Authors: Mohsenian Vahid , Hajirasouliha Iman , Filizadeh Reza
Published: November 2020

The eccentric bracing system equipped with vertical links is capable of providing high levels of stiffness, strength and ductility, and therefore, can be efficiently used for seismic retrofit of existing structures. This study aims to investigate the seismic reliability of steel moment-resisting frames retrofitted by this system using a novel combined series–parallel system approach. The seismic response of 4, 8 and 12-storey steel moment-resisting frames (MRFs) are evaluated under a set of design basis earthquakes (DBE) before and after retrofitting intervention. Adopting an engineering demand parameter approach (EDP-Based) for reliability assessment and development of analytical models for the frames using systems consisting of the series–parallel elements are the major distinctions between the present study and the other similar works. To estimate the global reliability of the frames, first, the reliability of each storey is individually derived based on various probable damage levels for the lateral-load resisting members. Then, the seismic reliability of the frame is globally obtained by combining the reliability of each storey for different damage levels in the lateral load-resisting subsystems. The results indicate significant impact of this type of bracing system on improvement of the performance level and load-carrying capacity of the frames along with reduction of the lateral displacements. It is shown that application of the vertical links can reduce the maximum inter-storey drifts by at least 60%, while it leads to at most 17% increase in the base shear. All retrofitted frames exhibited a performance level higher than the Life Safety (LS) when subjected to the DBE hazard level records (earthquakes with return period of 475 years). At the same level of earthquake intensity, in the cases when the drift corresponding to the LS performance level is used as the target, the reliability of the retrofitted frames was improved by more than 90% compared to the original frames for all damage states developed in the vertical links.
How Much You See Is How You Respond: The Curvilinear Relationship Between the Frequency of Observed Unethical Behavior and The Whistleblowing Intention
Authors: Kaptein Muel
Published: November 2020

This article uses a sample of 3076 employees working in the USA to examine the relationship between the frequency of unethical behavior that employees observe in their organization and their intention to whistleblow. The results confirm the expected curvilinear relationship based on the Focus Theory of Normative Conduct. This relationship is a combination of a diminishing negative relationship between the frequency of observed unethical behavior and the intention to whistleblow internally and a linear positive relationship between the frequency of observed unethical behavior and the intention to whistleblow externally. The beliefs of employees about how supportive their management is when handling whistleblowing reports moderates the relationship between the frequency of unethical behavior employees observe and their intention to whistleblow.
Responding to COVID-19: New Trends in Social Workers’ Use of Information and Communication Technology
Authors: Mishna Faye , Milne Elizabeth , Bogo Marion , Pereira Luana F.
Published: November 2020

COVID-19 changed the context for Information and Communication Technology (ICT) use globally. With face-to-face practice restricted, almost all communication with clients shifted to ICTs. Starting in April 2019, we conducted semi-structured interviews with social workers from four agencies serving diverse populations in a large urban centre, with the aim of exploring social workers’ informal ICT use with clients. Approximately 6 weeks after the cessation of face-to-face practice in March 2020 due to COVID-19 measures, we re-interviewed social workers (n = 11) who had participated in our study. Second interviews were based on a newly developed interview guide that explored social workers’ use of ICTs with clients in the context of COVID-19. Analysis of transcribed interviews revealed that the context of COVID-19 had generated two main themes. One, a paradigm shift for social workers was characterized by (a) diverse ICT options, (b) client-driven approach, and (c) necessary creativity. The second theme entails the impact of this transition which involved (a) greater awareness of clients’ degree of access, (b) confidentiality and privacy, and (c) professional boundaries. We discuss these themes and sub-themes and present implications for practice and research in a Post-COVID-19 world.
Connexivity and the Pragmatics of Conditionals
Authors: Kapsner Andreas
Published: November 2020

In this paper, I investigate whether the intuitions that make connexive logics seem plausible might lie in pragmatic phenomena, rather than the semantics of conditional statements. I conclude that pragmatics indeed underwrites these intuitions, at least for indicative statements. Whether this has any effect on logic choice (and what that effect might be), however, heavily depends on one’s semantic theory of conditionals and on how one chooses to logically treat pragmatic failures.
Coordinating expectations through central bank projections
Authors: Mokhtarzadeh Fatemeh , Petersen Luba
Published: November 2020

Central banks are increasingly communicating their economic outlook in an effort to manage the public and financial market participants’ expectations. We provide original causal evidence that the information communicated and the assumptions underlying a central bank’s projection can matter for expectation formation and aggregate stability. Using a between-subject design, we systematically vary the central bank’s projected forecasts in an experimental macroeconomy where subjects are incentivized to forecast the output gap and inflation. Without projections, subjects exhibit a wide range of heuristics, with the modal heuristic involving a significant backward-looking component. Ex-Ante Rational dual projections of the output gap and inflation significantly reduce the number of subjects’ using backward-looking heuristics and nudge expectations in the direction of the rational expectations equilibrium. Ex-Ante Rational interest rate projections are cognitively challenging to employ and have limited effects on the distribution of heuristics. Adaptive dual projections generate unintended inflation volatility by inducing boundedly-rational forecasters to employ the projection and model-consistent forecasters to utilize the projection as a proxy for aggregate expectations. All projections reduce output gap disagreement but increase inflation disagreement. Central bank credibility is significantly diminished when the central bank makes larger forecast errors when communicating a relatively more complex projection. Our findings suggest that inflation-targeting central banks should strategically ignore agents’ irrationalities when constructing their projections and communicate easy-to-process information.
Surface bundles over surfaces: new inequalities between signature, simplicial volume and Euler characteristic
Authors: Bucher Michelle , Campagnolo Caterina
Published: November 2020

We present three new inequalities tying the signature, the simplicial volume and the Euler characteristic of surface bundles over surfaces. Two of them are true for any surface bundle, while the third holds on a specific family of surface bundles, namely the ones that arise through ramified coverings. These are among the main known examples of bundles with non-zero signature.

Published: November 2020

An interrupted time series with a parallel control group (ITS-CG) design is a powerful quasi-experimental design commonly used to evaluate the effectiveness of an intervention, on accelerating uptake of useful public health products, and can be used in the presence of regularly collected data. This paper illustrates how a segmented Poisson model that utilizes general estimating equations (GEE) can be used for the ITS-CG study design to evaluate the effectiveness of a complex social accountability intervention on the level and rate of uptake of modern contraception. The intervention was gradually rolled-out over time to targeted intervention communities in Ghana and Tanzania, with control communities receiving standard of care, as per national guidelines. Two ITS GEE segmented regression models are proposed for evaluating of the uptake. The first, a two-segmented model, fits the data collected during pre-intervention and post-intervention excluding that collected during intervention roll-out. The second, a three-segmented model, fits all data including that collected during the roll-out. A much simpler difference-in-difference (DID) GEE Poisson regression model is also illustrated. Mathematical formulation of both ITS-segmented Poisson models and that of the DID Poisson model, interpretation and significance of resulting regression parameters, and accounting for different sources of variation and lags in intervention effect are respectively discussed. Strengths and limitations of these models are highlighted. Segmented ITS modelling remains valuable for studying the effect of intervention interruptions whether gradual changes, over time, in the level or trend in uptake of public health practices are attributed by the introduced intervention.

Quantum Spacetime and the Universe at the Big Bang, Vanishing Interactions and Fading Degrees of Freedom
Authors: Doplicher Sergio , Morsella Gerardo , Pinamonti Nicola
Published: November 2020

As discussed in Bahns et al. (2015) fundamental physical principles suggests that, close to cosmological singularities, the effective Planck length diverges, hence a “quantum point” becomes infinitely extended. We argue that, as a consequence, at the origin of times spacetime might reduce effectively to a single point and interactions disappear. This conclusion is supported by converging evidences in two different approaches to interacting quantum fields on Quantum Spacetime: (1) as the Planck length diverges, the field operators evaluated at a “quantum point” converge to zero, and so do the lowest order expressions for interacting fields in the Yang Feldman approach; (2) in the same limit, we find convergence of the interacting vacuum to the free one at all perturbative orders. The latter result is obtained using the adaptation, performed in Doplicher et al. (2020), of the methods of perturbative Algebraic Quantum Field Theory to Quantum Spacetime, through a novel picture of the effective Lagrangian, which maintains the ultraviolet finiteness of the perturbation expansion and allows one to prove also the existence of the adiabatic limit. It remains an open question whether the S matrix itself converges to unity and whether the limit in which the effective Planck length diverges is a unique initial condition or an unreachable limit, and only different asymptotics matter.
Post-Stroke Working Memory Dysfunction: A Meta-Analysis and Systematic Review
Authors: Lugtmeijer Selma , Lammers Nikki A. , de Haan Edward H. F. , de Leeuw Frank-Erik , Kessels Roy P. C.
Published: November 2020

This review investigates the severity and nature of post-stroke working memory deficits with reference to the multi-component model of working memory. We conducted a systematic search in PubMed up to March 2019 with search terms for stroke and memory. Studies on adult stroke patients, that included a control group, and assessed working memory function, were selected. Effect sizes (Hedges’ g) were extracted from 50 studies (in total 3,084 stroke patients) based on the sample size, mean and standard deviation of patients and controls. Performance of stroke patients was compared to healthy controls on low-load (i.e. capacity) and high-load (executively demanding) working memory tasks, grouped by modality (verbal, non-verbal). A separate analysis compared patients in the sub-acute and the chronic stage. Longitudinal studies and effects of lesion location were systematically reviewed. Stroke patients demonstrated significant deficits in working memory with a moderate effect size for both low-load (Hedges’ g = -.58 [-.82 to -.43]) and high-load (Hedges’ g = -.59 [-.73 to -.45]) tasks. The effect sizes were comparable for verbal and non-verbal material. Systematically reviewing the literature showed that working memory deficits remain prominent in the chronic stage of stroke. Lesions in a widespread fronto-parietal network are associated with working memory deficits. Stroke patients show decrements of moderate magnitude in all subsystems of working memory. This review clearly demonstrates the global nature of the impairment in working memory post-stroke.
Photosynthesis of the Cyanidioschyzon merolae cells in blue, red, and white light
Authors: Parys Eugeniusz , Krupnik Tomasz , Kułak Ilona , Kania Kinga , Romanowska Elżbieta
Published: November 2020

Photosynthesis and respiration rates, pigment contents, CO2compensation point, and carbonic anhydrase activity inCyanidioschizon merolaecultivated in blue, red, and white light were measured. At the same light quality as during the growth, the photosynthesis of cells in blue light was significantly lowered, while under red light only slightly decreased as compared with white control. In white light, the quality of light during growth had no effect on the rate of photosynthesis at low O2and high CO2concentration, whereas their atmospheric level caused only slight decrease. Blue light reduced markedly photosynthesis rate of cells grown in white and red light, whereas the effect of red light was not so great. Only cells grown in the blue light showed increased respiration rate following the period of both the darkness and illumination. Cells grown in red light had the greatest amount of chlorophyll a, zeaxanthin, and β-carotene, while those in blue light had more phycocyanin. The dependence on O2concentration of the CO2compensation point and the rate of photosynthesis indicate that this alga possessed photorespiration. Differences in the rate of photosynthesis at different light qualities are discussed in relation to the content of pigments and transferred light energy together with the possible influence of related processes. Our data showed that blue and red light regulate photosynthesis inC. merolaefor adjusting its metabolism to unfavorable for photosynthesis light conditions.
Discrimination of POVMs with rank-one effects
Authors: Krawiec Aleksandra , Pawela Łukasz , Puchała Zbigniew
Published: November 2020

The main goal of this work is to provide an insight into the problem of discrimination of positive operator-valued measures with rank-one effects. It is our intention to study multiple-shot discrimination of such measurements, that is the case when we are able to use to unknown measurement a given number of times. Furthermore, we are interested in comparing two possible discrimination schemes: the parallel and adaptive ones. To this end, we construct a pair of symmetric informationally complete positive operator-valued measures which can be perfectly discriminated in a two-shot adaptive scheme but cannot be distinguished in the parallel scheme. On top of this, we provide an explicit algorithm which allows us to find this adaptive scheme.
Are the psychophysical laws fine-tuned?
Authors: Cavedon-Taylor Dan
Published: November 2020

Neil Sinhababu (Am Philos Q 54(1):89–98, 2017) has recently argued against the fine-tuning argument for God. They claim that the question of the universe’s fine-tuning ought not be ‘why is the universe so hospitable to life?’ but rather ‘why is the universe so hospitable to morally valuable minds?’ and that, moreover, the universe isn’t so hospitable. For it is metaphysically possible that psychophysical laws be substantially more permissive than they in fact are, allowing for the realisation of morally valuable consciousness by exceptionally simple physical states and systems, rather than the complex states of brains. I reply that Sinhababu’s argument rests upon unsupported claims and that we have reason to doubt that an omnibenevolent God would make the psychophysical laws more permissive than they in fact are.
Economic Freedom and People’s Regard for Education
Authors: Feldmann Horst
Published: November 2020

Using data on 48 countries, this paper finds that people in economically freer countries care more about education. This is probably mainly because economic freedom enables them and their children to achieve higher returns to education. The magnitude of the estimated effect is substantial. The paper combines individual-level data from the World Values Survey with country-level data on economic freedom and other relevant factors. It controls for all relevant characteristics of survey respondents as well as for potentially confounding country-level characteristics. It also addresses potential endogeneity of economic freedom.
1-Naphthols as components for multifunctional material systems (MFMS): the molecular modeling approach
Authors: Radkowska Ilona , Bragiel Piotr
Published: November 2020

Increasing research interests have been paid to developing efficient multifunctional material systems (MFMS) by using various composite materials, owing to their useful properties and good stability. Here, we systematically studied 1-naphthols, especially how the type and position of a substituent influence the reactivity and properties, using different electron-directing groups. During computations, important preparation guidelines for thiol derivatives of 1-naphthol were obtained. It is very interesting to note that some molecules could exhibit intramolecular O–H–O interactions. Careful theoretical investigation reveals that all the tested compounds are stable and the molecules with substituents in positions 4 and 8 are the least reactive. It is also worth noting that for the stability and polarizability tensor values, it is more favorable when both substituents are in the same benzene ring. Among tested 1-naphthols, the greatest values of alpha, beta, and gamma are more than 5, 60, and 110 times better respectively, than in the urea molecule; the change of electron-withdrawing group (EWG) to electron-donating group (EDG) increases NLO effects. This study provided a new scope of 1-naphthols applicability by using them as anti-corrosion materials and as very good materials for NLO devices due to the high stability of the aromatic structure coupled with polarity given by the substituents. Also, the understanding of IR vibrations for more complex organic compounds with thiol substituent has been improved.
On the Role of Mental Health Activities for Teachers’ Work and Life
Authors: Hofmann Hanna , Groß Daniel , Kohlmann Carl-Walter
Published: November 2020

Everyday behavior is getting increasingly attention, both in the prevention of mental impairment and the promotion of mental health – within and beyond the work context. The present study aimed to identify the importance of mental health activities for well-being and positive functioning of teachers, while taking affectivity into account. Teachers are confronted with various stressors, and identifying predictors of teachers’ well-being and positive functioning is important, not only for teachers’ personal health, but also for their students’ well-being and achievement. Based on the Broaden and Build (B&B) theory and Conservation of Resources (COR) theory, we assumed that (1) the practice of mental health activities is associated with well-being (i.e., positive mental health) and positive functioning (i.e., healthy and unhealthy work-related behavior and experiences), and that (2) mental health activities mediate the association between affectivity and the respective outcomes. These assumptions were tested in a sample of 326 German teachers (75% female, age: M = 44, SD = 11.85). The practice of mental health activities was associated with more positive mental health, more healthy work-related behavior and experiences, and less unhealthy work-related behavior and experiences. Moreover, mental health activities partly explained the relationship between affectivity and the respective outcomes. The present findings indicate the potential of mental health activities for mental health promotion in teachers but future studies are recommended in order to establish causal effects.
Exposure of the SH-SY5Y Human Neuroblastoma Cells to 50-Hz Magnetic Field: Comparison Between Two-Dimensional (2D) and Three-Dimensional (3D) In Vitro Cultures

Published: November 2020

We here characterize the response to the extremely low-frequency (ELF) magnetic field (MF, 50 Hz, 1 mT) of SH-SY5Y human neuroblastoma cells, cultured in a three-dimensional (3D) Alvetex® scaffold compared to conventional two-dimensional (2D) monolayers. We proved that the growing phenotype of proliferating SH-SY5Y cells is not affected by the culturing conditions, as morphology, cell cycle distribution, proliferation/differentiation gene expression of 3D-cultures overlap what reported in 2D plates. In response to 72-h exposure to 50-Hz MF, we demonstrated that no proliferation change and apoptosis activation occur in both 2D and 3D cultures. Consistently, no modulation of Ki67, MYCN, CCDN1, and Nestin, of invasiveness and neo-angiogenesis-controlling genes (HIF-1α, VEGF, and PDGF) and of microRNA epigenetic signature (miR-21-5p, miR-222-3p and miR-133b) is driven by ELF exposure. Conversely, intracellular glutathione content and SOD1 expression are exclusively impaired in 3D-culture cells in response to the MF, whereas no change of such redox modulators is observed in SH-SY5Y cells if grown on 2D monolayers. Moreover, ELF-MF synergizes with the differentiating agents to stimulate neuroblastoma differentiation into a dopaminergic (DA) phenotype in the 3D-scaffold culture only, as growth arrest and induction of p21, TH, DAT, and GAP43 are reported in ELF-exposed SH-SY5Y cells exclusively if grown on 3D scaffolds. As overall, our findings prove that 3D culture is a more reliable experimental model for studying SH-SY5Y response to ELF-MF if compared to 2D conventional monolayer, and put the bases for promoting 3D systems in future studies addressing the interaction between electromagnetic fields and biological systems.
A Systematic Review for Service Humanoid Robotics Model in Hospitality
Authors: Yang Jiaji , Chew Esyin
Published: November 2020

Nowadays, the Fourth Industrial Revolution has brought artificial intelligence to the forefront, and more and more intelligent robots begin to be used in the hospitality industry. In this study, the application of service humanoid robots in the hospitality industry is investigated based on Cardiff Metropolitan University EUREKA Robotics Lab’s robot as reported by Lab (in Eureka robotics lab, 2017, https://www.cardiffmet.ac.uk/technologies/Pages/EUREKA-Robotics-Lab.aspx). The research ontology of this study is post-positivism. The research philosophy of this research is phenomenology. Phenomenological studies have indicated that this phenomenon can only be truly understood and experienced through subjective immersive research directly involving researchers, and the interaction among researchers is an integral part of the research. In this study, the data are collated through case researches and experimental interviews. Finally, Some proposals for transforming the traditional hospitality industry into the direction of intelligence is summarized. In future research, a technical model combining artificial intelligence will be further developed.

If in addition an s-extremal Riemann surface has the maximal total number of ovals, then it shall simply be called extremal. In the main result of the paper we find all the families of extremal Riemann surfaces of even genera, depending on if one of the symmetries is fixed-point free or not.

Microstructure and mechanical properties of 3D Cf/SiBCN composites fabricated by polymer infiltration and pyrolysis
Authors: Chen Bowen , Ding Qi , Ni Dewei , Wang Hongda , Ding Yusheng , Zhang Xiangyu , Dong Shaoming
Published: November 2020

In this work, three-dimensional (3D) Cf/SiBCN composites were fabricated by polymer infiltration and pyrolysis (PIP) with poly(methylvinyl)borosilazane as SiBCN precursor. The 3D microstructure evolution process of the composites was investigated by an advanced X-ray computed tomography (XCT). The effect of dicumyl peroxide (DCP) initiator addition on the crosslinking process, microstructure evolution, and mechanical properties of the composites were uncovered. With the addition of a DCP initiator, the liquid precursor can cross-linking to solid-state at 120 °C. Moreover, DCP addition decreases the release of small molecule gas during pyrolysis, leading to an improved ceramic yield 4.67 times higher than that without DCP addition. After 7 PIP cycles, density and open porosity of the final Cf/SiBCN composite with DCP addition are 1.73 g·cm−3 and ∼10%, respectively, which are 143.0% higher and 30.3% lower compared with the composites without DCP addition. As a result, the flexural strength and elastic modulus of Cf/SiBCN composites with DCP addition (371 MPa and 31 GPa) are 1.74 and 1.60 times higher than that without DCP addition (213 MPa and 19.4 GPa), respectively.
Great War, Religious Dimensions
Authors: Wintermute Bobby
Published: November 2020

The First World War was a transformative event, affecting international culture, economics, and geopolitics. Though often presented as the moment heralding a new secular era of modernity, in actuality the war experience was grounded in religious faith and ritual for many participants. This Element examines how religion was employed by the state to solicit support and civic participation, while also being subordinated to the strategic and operational demands of the combatant armies. Even as religion was employed to express dissent, it was also used as a coercive tool to ensure compliance with the wartime demands of the state on civilians.
LGBTQ Film Festivals
Authors: Damiens Antoine
Published: November 2020

While scholars have theorized major film festivals, they have ignored smaller, ephemeral, events. In taking seriously minor European and North-American LGBT festivals which often only exist as traces within archival collections, this book revisits festival studies' methodological and theoretical apparatuses. As the first 'critique' of festival studies from within, LGBTQ Film Festivals argues that both festivals and queer film cultures are by definition ephemeral. The book is organized around two concepts: First, 'critical festival studies' examines the political project and disciplinary assumptions that structure festival research. Second, 'the festival as a method' pays attention to festivals' role as producers of knowledge: it argues that festivals are not mere objects of research but also actors already shaping academic, industrial, and popular cinematic knowledge. Drawing on my experience on the festival circuit, this book pays homage to the labour of queer organizers, critics, and scholars and opens up new avenues for festival research.
Lexicalisation of tonal downstep in Yoruba
Authors: Adeniyi Kolawole
Published: November 2020

This work challenges the assumption that tonal downstep is a juncture feature in Yoruba by providing data, both from everyday conversation and from classical Yoruba dictionaries, which prove that the phenomenon is part of the lexical composition of many Yoruba words. It is further argued that the derivational path of some of the words having downstep has already been lost. It is also reported that the Assimilated Low Tone phenomenon, which is an indication that the delinked Low tone triggering downstep is still active in the phonology, is currently being lost in many dialects, which is giving way to more classical-like downstep in the language. Cross- dialectal evidence from Oyo, Ibadan, Onko, and Ijebu dialects, as well as from pitch tracks are provided to support the arguments and it is suggested that Yoruba is developing downstep via Assimilated Low Tone, and that this process has now reached an advanced stage.
Asymmetric pulse effects on pair production in polarized electric fields
Authors: Olugh Obulkasim , Li Zi-Liang , Xie Bai-Song
Published: November 2020

Using the Dirac–Heisenberg–Wigner formalism, effects of the asymmetric pulse shape on the generation of electron-positron pairs in three typical polarized fields, i.e., linear, middle elliptical and circular fields, are investigated. Two kinds of asymmetries for the falling pulse length, short and elongated, are studied. We find that the interference effect disappears with the shorter pulse length and that the peak value of the momentum spectrum is concentrated in the center of the momentum space. In the case of the extending falling pulse length, a multiring structure without interference appears in the momentum spectrum. Research results show that the momentum spectrum is very sensitive to the asymmetry of the pulse as well as to the polarization of the fields. We also find that the number density of electron-positron pairs under different polarizations is sensitive to the asymmetry of the electric field. For the short falling pulse, the number density can be significantly enhanced by over two orders of magnitude. These results could be useful in planning high-power and/or high-intensity laser experiments.
Evaluation of the negative predictive value of methicillin-resistant Staphylococcus aureus nasal swab screening in patients with acute myeloid leukemia
Authors: Perreault Sarah K. , Binks Bailee , McManus Dayna S. , Topal Jeffrey E.
Published: November 2020

Objective:

Methicillin-resistant Staphylococcus aureus (MRSA) nasal swabs are utilized to guide the discontinuation of empiric MRSA therapy. In multiple studies, MRSA nasal swabs have been shown to have a negative predictive value (NPV) of ~99% in non-oncology patients with pneumonia and other infections. We evaluated the performance characteristics of a negative MRSA nasal swab in the acute myeloid leukemia (AML) populaion to determine its NPV.

Design:

Retrospective chart review.

Patients:

This study included adult AML patients with a suspected infection and a MRSA nasal swab collected between 2013 and 2018.

Methods:

MRSA nasal swab and culture-documented infections were identified to determine the sensitivity, specificity, NPV, and positive predictive value of the MRSA nasal swabs.

Results:

In total, 194 patients were identified, and 484 discrete encounters were analyzed. Overall, 468 (97%) encounters had a negative MRSA nasal swab upon admission with no cultured documented MRSA infection during their hospitalization. However, 3 encounters (0.6%) had a negative MRSA nasal swab with a subsequent cultured documented MRSA infection during their admission. Identified infections were bacteremia (n = 2) and confirmed pneumonia (n = 1). MRSA nasal swab had a sensitivity of 62% (95% CI, 0.24–0.91), specificity of 98% (95% CI, 0.96–0.99), positive predictive value of 38% (95% CI, 0.21–0.6), and NPV of 99% (95% CI, 0.98–1).

Conclusions:

A negative MRSA nasal swab has a 99% NPV for subsequent MRSA infections in AML patients with no prior history of MRSA colonization or infection. Based on these findings, a negative MRSA nasal swab can help guide de-escalation of empiric MRSA antibiotic therapy.
Personality traits in psychosis and psychosis risk linked to TSPO expression: a neuroimmune marker
Authors: Gerritsen Cory , Iyengar Yajur , DaSilva Tania , Koppel Alex , Rusjan Pablo , Bagby R. Michael , Mizrahi Romina
Published: November 2020

Personality has been correlated with differences in cytokine expression, an indicator of peripheral inflammation; however, the associations between personality and central markers of inflammation have never been investigated in vivo in humans. Microglia are the resident macrophages of the central nervous system, and the first responders to tissue damage and brain insult. Microglial activation is associated with elevated expression of translocator protein 18kDa (TSPO), which can be imaged with positron emission tomography (PET) to quantify immune activation in the human brain. This study aimed to investigate the association between personality and TSPO expression across the psychosis spectrum. A total of 61 high-resolution [18F]FEPPA PET scans were conducted in 28 individuals at clinical high risk (CHR) for psychosis, 19 First-Episode Psychosis (FEP), and 14 healthy volunteers (HVs), and analyzed using a two-tissue compartment model and plasma input function to obtain a total volume of distribution (VT) as an index of brain TSPO expression (controlling for the rs6971 TSPO polymorphism). Personality was assessed using the Revised NEO Personality Inventory (NEO-PI-R). We found TSPO expression to be specifically associated with neuroticism. A positive association between TSPO expression and neuroticism was found in HVs, in contrast to a nonsignificant, negative association in CHR and significant negative association in FEP. The TSPO-associated neuroticism trait indicates an unexplored connection between neuroimmune activation and personality that varies across the psychosis spectrum.

Published: November 2020

We determine the (non-)triviality of Samelson products of inclusions of factors of the mod p decomposition of $G_{(p)}$ for $(G,p)=(E_7,5),(E_7,7),(E_8,7)$. This completes the determination of the (non-)triviality of those Samelson products in p-localized exceptional Lie groups when G has p-torsion-free homology.
Access to medicines in Turkey: Evaluation of the process of medicines brought from abroad
Authors: Atikeler Enver Kağan , Leufkens H.G.M. (Bert) , Goettsch Wim
Published: November 2020

Objective

Turkey's health reforms started in 2003 with providing changes in regulatory, financing, and healthcare services. Access to health care and pharmaceuticals increased rapidly, and this resulted with an increase in public pharmaceutical expenditures. Our study aims to quantify and to evaluate the impact of a specific process within the Turkish system called “Medicines Brought From Abroad" (MBFA).

Methods

We reviewed the general reimbursement legislations of Social Security Institution (SSI), the guideline on MBFA, the SSI reimbursement list, the list of MBFA published by the Ministry of Health to describe the current supply mechanism of medicines and, in particular, the role of MBFA.

Results

Total costs of the of MBFA medicines over the period 2011–17 went up to more than $520 million, which takes 7.5 percent of total public pharmaceutical expenditure for 2017. Our results showed that MBFA provides access to many orphan drugs and in total, forty-two orphan drugs listed in MBFA accounted for 83 percent of all MBFA budget in the year 2017. Nine of the top ten MBFA medicines were orphan drugs and total costs were $408 million. The highest budget impact was for eculizumab for “paroxysmal nocturnal hemoglobinuria” (PNH), covering 31 percent of total MBFA costs and 2.3 percent of overall drug costs in 2017.

Conclusions

Turkey faced significant challenges for creating an access pathway for innovative medicines while continuing the sustainability of the public pharmaceutical budget like many other countries. Therefore, it may be argued that Turkey needs to create an independent health technology assessment organization to provide sustainable access to medicines in the future.
