Published: March 2021

There has been a drive towards increased digitalisation in healthcare. The aim was to provide a snapshot of current apps, instant messaging, and smartphone photography use in paediatric emergency care. A web-based self-report questionnaire was performed. Individual physicians working in paediatric emergency care recorded their personal practice. One hundred ninety-eight medical doctors completed the survey. Eight percent of respondents had access to institutional mobile devices to run medical apps. Eighty-six percent of respondents used medical apps on their personal mobile device, with 78% using Apple iOS devices. Forty-seven percent of respondents used formulary apps daily. Forty-nine percent of respondents had between 1–5 medical apps on their personal mobile device. Respondents who used medical apps had a total of 845 medical apps installed on their personal device, accounted for by 56 specific apps. The British National Formulary (BNF/BNFc) app was installed on the personal mobile device of 96% of respondents that use medical apps. Forty percent of respondents had patient confidentiality concerns when using medical apps. Thirty-eight percent of respondents have used consumer instant messaging services, 6% secure specialist messaging services, and 29% smartphone photography when seeking patient management advice.

Conclusion

App use on the personal mobile devices, in the absence of access to institutional devices, was widespread, especially the use of a national formulary app. Instant messaging and smartphone photography were less common. A strategic decision has to be made to either provide staff with institutional devices or use software solutions to address data governance concerns when using personal devices.

What is Known:• mHealth use by junior doctors and medical students is widespread.• Clinicians’ use of instant messaging apps such as WhatsApp is the widespread in the UK and Ireland, in the absence of alternatives.

What is New:• Personal mobile device use was widespread in the absence of alternatives, with the British National Formulary nearly universally downloaded to physicians’ personal mobile devices.• A third of respondents used instant messaging and smartphone photography on their personal mobile device when seeking patient management advice from other teams in the absence of alternatives.

Neonatal screening for congenital primary hypothyroidism (CH) may not distinguish between transient (TCH) and permanent dysfunction (PCH), causing potential overtreatment and concerns in affected families. To specify the indication for interruption of therapy, we analysed the German registry “HypoDok” for infants with CH, which oversees 1625 patients from 49 participating centres in Germany and Austria from 1997 until today. A total of 357 patients with a thyroid gland in loco typico were identified and retrospectively grouped according to cessation (TCH, n = 24) or continuation (PCH, n = 333) of l-thyroxine (l-T4) treatment at 2 years of age. The receiver operating characteristic (ROC) analysis was performed to identify cutoffs predicting TCH by screening TSH concentrations and l-T4 dosages. Gestational ages, birth weights and prevalence of associated malformations were comparable in both groups. The cutoff screening TSH concentration was 73 mU/L. The cutoff daily l-T4 dosage at 1 year was 3.1 μg/kg (90% sensitivity, 63% specificity; 36 μg/day) and at 2 years of age 2.95 μg/kg (91% sensitivity, 59% specificity; 40 μg/day). At 2 years of age, specificity (71%) increased when both of these parameters were considered together.

Conclusion: The decision to continue or cease l-T4 treatment at 2 years of age in CH patients diagnosed in neonatal screening may be based on their screening TSH concentrations and individual l-T4 dosages at 1 and 2 years of age. Thus, TCH and PCH may be distinguished; overtreatment avoided; and affected families reassured.

What is Known:• The course of congenital primary hypothyroidism may be transient, causing potential overtreatment.• The dose ofl-thyroxine at 1 or 2 years of age may predict a transient course of primary congenital hypothyroidism.

What is New:• TSH screening concentration andl-thyroxine dosages at 1 and 2 years of age represent reliable predictors for transient congenital primary hypothyroidism with higher sensitivity and specificity when considered together in order to select eligible patients who qualify for treatment withdrawal.
Self-Diffusion Coefficients, Aggregation Numbers and the Range of Existence of Spherical Micelles of Oxyethylated Alkylphenols
Authors: Arkhipov Victor P. , Kuzina Natalia A. , Filippov Andrei
Published: March 2021

Aggregation numbers were calculated based on measurements of the self-diffusion coefficients, the effective hydrodynamic radii of micelles and aggregates of oxyethylated alkylphenols in aqueous solutions. On the assumption that the radii of spherical micelles are equal to the lengths of fully extended neonol molecules, the limiting values of aggregation numbers corresponding to spherically shaped neonol micelles were calculated. The concentration and temperature ranges under which spherical micelles of neonols are formed were determined.
Gesundheitskompetenz und Notfallverhalten
Authors: Wehler Markus , Kalch Anja , Bilandzic Helena , Händl Thomas
Published: March 2021

Hintergrund

Die Anzahl an Patienten in Notaufnahmen steigt seit Jahren an. Im Besonderen wächst der Anteil an Patienten mit einem nichtdringlichen Behandlungsbedarf. Bislang ist unklar, ob dies in Deutschland auch auf eine eingeschränkte Gesundheitskompetenz zurückgeführt werden kann.

Ziel der Arbeit

Ziel der Studie war es, die Gesundheitskompetenz (GK) von Notfallpatienten mit nichtdringlichem Behandlungsbedarf zu erfassen, mit allgemeinen Bevölkerungsdaten zur GK zu vergleichen und Zusammenhänge mit der subjektiv empfundenen notfallmedizinischen Versorgung zu betrachten.

Material und Methode

Es wurde eine Querschnittsbefragung in der zentralen Notaufnahme und der angeschlossenen kassenärztlichen Bereitschaftspraxis (KVB-Praxis) des Universitätsklinikums Augsburg durchgeführt. Insgesamt wurden 448 Patienten mit nichtdringlichem Versorgungsbedarf befragt.

Ergebnisse

Es zeigt sich, dass die GK der Notfallpatienten schlechter ausfällt als die der deutschen Gesamtpopulation. Patienten mit niedriger GK nehmen eine höhere subjektive Behandlungsdringlichkeit wahr, kennen signifikant seltener alternative Anlaufstellen zur Behandlung und möchten nach hausärztlicher Versorgung häufiger in der Notaufnahme oder der KVB-Praxis eine zweite Meinung einholen.

Diskussion

Die Ergebnisse zeigen einen Handlungsbedarf für eine Verbesserung der Gesundheitskompetenz auf. Dabei sind insbesondere die aktuellen strukturellen Veränderungen der Notfallversorgung in Deutschland zu berücksichtigen.
Cervical Muscle Activation Due to an Applied Force in Response to Different Types of Acoustic Warnings
Authors: Homayounpour Mohammad , Gomez Nicholas G. , Vasavada Anita N. , Merryweather Andrew S.
Published: March 2021

Mild traumatic brain injury (mTBI) and whiplash-associated disorder are the most common head and neck injuries and result from a sudden head or body acceleration. The head and neck injury potential is correlated with the awareness, level of muscle activation, and posture changes at the time of the perturbation. Environmental acoustic stimuli or a warning system can influence muscle activation and posture during a head perturbation. In this study, different acoustic stimuli, including Non-Directional, Directional, and Startle, were provided 1000 ms before a head impact, and the amplitude and timing of cervical muscle electromyographic (EMG) data were characterized based on the type of warning. The startle warning resulted in 49% faster and 80% greater EMG amplitude compared to the Directional and Non-Directional warnings after warning and before the impact. The post-impact peak EMG amplitudes in Unwarned trials were lower by 18 and 21% in the retraction and rebound muscle groups, respectively, compared to any of the warned conditions. When there was no warning before the impact, the retraction and rebound muscle groups also reached their maximum activation 38 and 54 ms sooner, respectively, compared to the warned trials. Based on these results, the intensity and complexity of information that a warning sound carries change the muscle response before and after a head impact and has implications for injury potential.
‘Seeing with Empty Eyes’: a systems approach to understand climate change and mental health in Bangladesh
Authors: Hayward Gemma , Ayeb-Karlsson Sonja
Published: March 2021

Bangladesh’s unique climate vulnerability is well-investigated but the mental health impacts of climate change remain relatively unexplored. Three databases were searched for English primary qualitative studies published between 2000 and 2020. Out of 1202 publications, 40 met the inclusion criteria. This systematic review applies a systems approach to further understand Bangladesh’s ‘climate-wellbeing’ network. The literature indicates diverse factors linking environmental stress and mental ill-health including four key themes: (1) post-hazard mental health risks, (2) human (im)mobility, (3) social tension and conflict, and (4) livelihood loss and economic hardship. This systems analysis also revealed that people’s mental wellbeing is strongly mediated by socio-economic status and gender. The article illustrates how multiple pathways may amplify stress, anxiety, violence, and psychological damage. Greater recognition of the ‘climate-wellbeing’ connections, and incorporation of mental health in current climate action and policy frameworks, will be an effective way to achieve a more sustainable future.
Minding mathematicians’ discourses in investigations of their feedback on students’ proofs: a case study
Authors: Kontorovich Igor’
Published: March 2021

This article presents a research apparatus for investigating and making sense of stories that emerge from feedback that mathematicians provide on students’ proofs. Using the commognitive framework, the notion of didactical discourse on proof is developed as a lens for conceptualizing mathematicians’ practice of feedback provision. The notion is accompanied by a tentative organizational frame, within which didacticians and mathematicians can operate as partners. The methodological affordances of this apparatus are illustrated with a case study of a research topologist, who taught a small, graduate course in topology. The emerged characteristics of her feedback and discourse are situated in the literature and used to sketch future research avenues.
Brain cancer incidence rates and the presence of nuclear reactors in US states: a hypothesis-generating study
Authors: Williamson Mark R. , Klug Marilyn G. , Schwartz Gary G.
Published: March 2021

Background

The etiology of brain cancer is poorly understood. The only confirmed environmental risk factor is exposure to ionizing radiation. Because nuclear reactors emit ionizing radiation, we examined brain cancer incidence rates in the USA in relation to the presence of nuclear reactors per state.

Methods

Data on brain cancer incidence rates per state for Whites by sex for three age groups (all ages, 50 and older, and under 50) were obtained from cancer registries. The location, number, and type of nuclear reactor, i.e., power or research reactor, was obtained from public sources. We examined the association between these variables using multivariate linear regression and ANOVA.

Results

Brain cancer incidence rates were not associated with the number of nuclear power reactors. Conversely, incidence rates per state increased with the number of nuclear research reactors. This was significant for both sexes combined and for males in the ‘all ages’ category (β = 0.08, p = 0.0319 and β = 0.12, p = 0.0277, respectively), and for both sexes combined in the’50 and older’ category (β = 0.18, p = 0.0163). Brain cancer incidence rates for counties with research reactors were significantly higher than the corresponding rates for their states overall (p = 0.0140). These findings were not explicable by known confounders.

Conclusions

Brain cancer incidence rates are positively associated with the number of nuclear research reactors per state. These findings merit further exploration and suggest new opportunities for research in brain cancer epidemiology.
Population and Climate Change: Consensus and Dissensus among Demographers
Authors: van Dalen Hendrik P. , Henkens Kène
Published: March 2021

What role does population play in thinking about the problem of climate change and some of its solutions? In a survey conducted between February and April 2020, we asked European demographers to state their views on the relationship between climate change and population developments, and asked them to rate their concern about climate change and other socio-demographic issues. We found that climate change is at the top of the list of demographers’ concerns, but that their sense of urgency with respect to taking action to redress global warming is not matched by their belief that population policy can make a crucial difference in reducing CO2emissions: demographers are highly divided on the question whether the global population size should be reduced to lower CO2emissions, as well as on the question whether family planning is an effective policy instrument.

Authors: Aasdahl Lene , Vasseljen Ottar , Gismervik Sigmund Østgård , Johnsen Roar , Fimland Marius Steiro
Published: March 2021

PurposeThere is a lack of results on long-term effects of return to work interventions. We previously reported that an inpatient multimodal occupational rehabilitation program (I-MORE) was more effective in reducing sickness absence and facilitating return to work (RTW) at 12 months follow-up compared to an outpatient program that consisted mainly of Acceptance and Commitment Therapy (O-ACT). We now report the 2-year outcome data.MethodsA randomized clinical trial with parallel groups. Participants were 18–60 years old, sick listed with musculoskeletal, common mental or general/unspecified disorders. I-MORE lasted 3.5 weeks and consisted of ACT, physical training and work-related problem solving. O-ACT consisted mainly of 6 weekly sessions (2.5 h. each) of ACT in groups. Outcomes were cumulated number of days on medical benefits and time until sustainable RTW (1 month without medical benefits) during 2-years of follow-up, measured by registry data.ResultsFor the 166 randomized participants, the median number of days on medical benefits was 159 (IQR 59–342) for I-MORE vs 249 days (IQR 103–379; Mann–Whitney U test, p = 0.07), for O-ACT. At 2 years, 40% in I-MORE received long-term benefits (work assessment allowance) vs 51% in O-ACT. The crude hazard ratio (HR) for sustainable RTW was 1.59 (95% CI 1.04–2.42, p = 0.03) and the adjusted HR 1.77 (95% CI 1.14–2.75, p = 0.01), in favor of I-MORE.ConclusionsThe 2-year outcomes show that I-MORE had long-term positive effects on increasing work participation for individuals sick listed with musculoskeletal and mental disorders. Further follow-up and economic evaluations should be performed.
Passive and active vibration isolation under isolator-structure interaction: application to vertical excitations
Authors: Pérez-Aracil J. , Pereira E. , Díaz Iván M. , Reynolds P.
Published: March 2021

This work studies the influence of a vibration isolator on the response of a flexible base structure. Two strategies are compared: passive and active vibration isolation (PVI, AVI). Although the multiple advantages of AVI over PVI techniques are well known, their effect in the base structure has not to date been compared. This interaction has an important role in the performance of the general control system, especially when the vibration isolation system is not the only system on the base structure or when there are multiple isolators working simultaneously on it. In addition, the structural serviceability of the base structure can also be affected. The analysis of the vibration isolation problem is made from a wide perspective, including the effect that isolator has on the base structure. Hence assuming the base structure is a non-rigid system. The effect of the isolation system on the base response is studied for an extensive range of base structures, thus showing different possible scenarios. The influence is quantified by comparing the peak magnitude response of the base when both passive and active vibration isolation techniques are used. The theoretical results have been corroborated by undertaking experimental tests on a full-scale laboratory structure.
Effect of mass distribution on curving performance for a loaded wagon
Authors: Zhang Duo , Tang Yinying , Peng Qiyuan , Dong Chunjiao , Ye Yunguang
Published: March 2021

The location of wagon gravity center for a loaded wagon is underestimated in a vehicle–track coupled system. The asymmetric wheel load distribution due to loading offset significantly affects the wheel-rail contact state and seriously deteriorates the curving performance in conjunction with the height of gravity center and cant deficiency. Optimizing the location of gravity center and cruising velocity, therefore, is of interest to prevent the derailment and promote the transport capacity of railway wagons. This study aims to reveal the three-dimensional influencing mechanism of mass distribution on vehicle curving performance under different velocities. The wheel unloading ratio is regarded as the evaluation index. A simplified quasi-static model is established considering essential assumptions to highlight the influence of lateral and vertical offset on curving performance. For a more accurate description, the MBS models with various locations of wagon gravity center are built and then negotiate curves in different simulation cases. The simulation results reveal that the distribution of wheel unloading ratio determined by loading offset is like contour lines of ‘basin’. Based on the conclusions of quasi-static analysis and dynamics simulations, the regression equation is proposed and the fitting parameters are calculated for each simulation case. This paper demonstrates the necessity of optimizing the location of wagon gravity center according to the running condition and offers a novel strategy to load and transport the cargo by railway wagons.

Numerical Investigation of Successively Nucleating Bubbles During Subcooled Flow Boiling of FC-72 in Microgravity
Authors: Franz Benjamin , Sielaff Axel , Stephan Peter
Published: March 2021

For the present study numerical simulations of subcooled flow boiling of FC-72 in microgravity have been conducted to accompany boiling experiments performed in microgravity on the International Space Station (ISS). The numerical domain represents the geometry of the experimental test cell. For all simulations the open source framework OpenFOAM was employed, including extensions to the interFoam solver, which have been developed at the authors’ institute. A reference case has been defined applying intermediate values from the experimental parameter range as system parameters. This case has been examined thoroughly with regards to hydrodynamic phenomena and heat transfer during multiple, successive bubble cycles. Based on this reference case, the system parameters flow velocity, input heat flux, pre-heating time, and subcooling of the liquid bulk have been varied, and the impact of these quantities on bubble growth and movement as well as heat transfer have been studied. It was found, that an increased flow rate as well as increased subcooling lead to smaller bubbles and increased time between subsequent nucleations. A high input heat flux, an increased pre-heating time, and a decreased subcooling lead to a rapid cycle of bubble nucleation and coalescence.
“The street is ours”. A comparative analysis of street trading, Covid-19 and new street geographies in Harare, Zimbabwe and Kisumu, Kenya
Authors: Kiaka Richard , Chikulo Shiela , Slootheer Sacha , Hebinck Paul
Published: March 2021

This collaborative and comparative paper deals with the impact of Covid-19 on the use and governance of public space and street trade in particular in two major African cities. The importance of street trading for urban food security and urban-based livelihoods is beyond dispute. Trading on the streets does, however, not occur in neutral or abstract spaces, but rather in lived-in and contested spaces, governed by what is referred to as ‘street geographies’, evoking outbreaks of violence and repression. Vendors are subjected to the politics of municipalities and the state to modernize the socio-spatial ordering of the city and the urban food economy through restructuring, regulating, and restricting street vending. Street vendors are harassed, streets are swept clean, and hygiene standards imposed. We argue here that the everyday struggle for the street has intensified since and during the Covid-19 pandemic. Mobility and the use of urban space either being restricted by the city-state or being defended and opened up by street traders, is common to the situation in Harare and Kisumu. Covid-19, we pose, redefines, and creates ‘new’ street geographies. These geographies pivot on agency and creativity employed by street trade actors while navigating the lockdown measures imposed by state actors. Traders navigate the space or room for manoeuvre they create for themselves, but this space unfolds only temporarily, opens for a few only and closes for most of the street traders who become more uncertain and vulnerable than ever before, irrespective of whether they are licensed, paying rents for vending stalls to the city, or ‘illegally’ vending on the street.
$$\Gamma $$-Robust electricity market equilibrium models with transmission and generation investments
Authors: Çelebi Emre , Krebs Vanessa , Schmidt Martin
Published: March 2021

We consider uncertain robust electricity market equilibrium problems including transmission and generation investments. Electricity market equilibrium modeling has a long tradition but is, in most of the cases, applied in a deterministic setting in which all data of the model are known. Whereas there exist some literature on stochastic equilibrium problems, the field of robust equilibrium models is still in its infancy. We contribute to this new field of research by considering $$\Gamma $$
Γ
-robust electricity market equilibrium models on lossless DC networks with transmission and generation investments. We state the nominal market equilibrium problem as a mixed complementarity problem as well as its variational inequality and welfare optimization counterparts. For the latter, we then derive a $$\Gamma $$
Γ
-robust formulation and show that it is indeed the counterpart of a market equilibrium problem with robustified player problems. Finally, we present two case studies to gain insights into the general effects of robustification on electricity market models. In particular, our case studies reveal that the transmission system operator tends to act more risk-neutral in the robust setting, whereas generating firms clearly behave more risk-averse.

Goals and measures for analyzing power consumption data in manufacturing enterprises
Authors: Henning Sören , Hasselbring Wilhelm , Burmester Heinz , Möbius Armin , Wojcieszak Maik
Published: March 2021

The Internet of Things adoption in the manufacturing industry allows enterprises to monitor their electrical power consumption in real time and at machine level. In this paper, we follow up on such emerging opportunities for data acquisition and show that analyzing power consumption in manufacturing enterprises can serve a variety of purposes. In two industrial pilot cases, we discuss how analyzing power consumption data can serve the goals reporting, optimization, fault detection, and predictive maintenance. Accompanied by a literature review, we propose to implement the measures real-time data processing, multi-level monitoring, temporal aggregation, correlation, anomaly detection, forecasting, visualization, and alerting in software to tackle these goals. In a pilot implementation of a power consumption analytics platform, we show how our proposed measures can be implemented with a microservice-based architecture, stream processing techniques, and the fog computing paradigm. We provide the implementations as open source as well as a public show case allowing to reproduce and extend our research.
Structured climate financing: valuation of CDO on inhomogeneous asset pools
Authors: Packham N.
Published: March 2021

Recently, a number of structured funds have emerged as public-private partnerships with the intent of promoting investment in renewable energy in emerging markets. These funds seek to attract institutional investors by tranching the asset pool and issuing senior notes with a high credit quality. Financing of renewable energy (RE) projects is achieved via two channels: small RE projects are financed indirectly through local banks that draw loans from the fund’s assets, whereas large RE projects are directly financed from the fund. In a bottom-up Gaussian copula framework, we examine the diversification properties and RE exposure of the senior tranche. To this end, we introduce the LH++ model, which combines a homogeneous infinitely granular loan portfolio with a finite number of large loans. Using expected tranche percentage notional (which takes a similar role as the default probability of a loan), tranche prices and tranche sensitivities in RE loans, we analyse the risk profile of the senior tranche. We show how the mix of indirect and direct RE investments in the asset pool affects the sensitivity of the senior tranche to RE investments and how to balance a desired sensitivity with a target credit quality and target tranche size.
Four-quark matter—a new era of spectroscopy
Authors: Liu Zhiqing
Published: March 2021

In 1964, both Gell-Mann and Zweig proposed the famous Quark Model in particle physics, which tells us hadrons are built of three quarks (baryons) or quark anti-quark pair (mesons). However, the theory of strong interaction—QCD—allows the existing of hadrons beyond the conventional baryon and meson picture. These new hadron states are called exotic hadrons, and have been searched for over the past half century. In this review, I will introduce you the discovery of a new particle called Zc(3900), which is considered as the first convincing four-quark particle. The observation of four-quark matter gains great interest in particle physics, and triggered subsequent intensive study of exotic hadrons, which brings us to a new era of hadron spectroscopy and refreshes our knowledge about the hadronic matter in our universe.
Biology, Religion, and Philosophy
Authors: Peterson Michael , Venema Dennis
Published: March 2021

The intersection of biology and religion has spawned exciting new areas of academic research that raise issues central to understanding our own humanity and the living world. In this comprehensive and accessible survey, Michael L. Peterson and Dennis R. Venema explain the engagement between biology and religion on issues related to origins, evolution, design, suffering and evil, progress and purpose, love, humanity, morality, ecology, and the nature of religion itself. Does life have a chemical origin - or must there be a divine spark? How can religious claims about divine goodness be reconciled with widespread predation, suffering, and death in the animal kingdom? Peterson and Venema develop a philosophical discussion around such controversial questions. The book situates each topic in its historical, scientific, and theological context, making it the perfect introduction for upper-level undergraduates, graduate students, scholars, and the interested general reader.

Authors: Petrone Gianna , Brown Linda , Binder William , Naganathan Sonya , Pasichow Scott , Rybasack-Smith Heather , Duquette Cathy E. , Palka Dana R. , Musits Andrew N.
Published: March 2021

Objectives:

Coronavirus disease (COVID-19) has been identified as an acute respiratory illness leading to severe acute respiratory distress syndrome. As the disease spread, demands on health care systems increased, specifically the need to expand hospital capacity. Alternative care hospitals (ACHs) have been used to mitigate these issues; however, establishing an ACH has many challenges. The goal of this session was to perform systems testing, using a simulation-based evaluation to identify areas in need of improvement.

Methods:

Four simulation cases were designed to depict common and high acuity situations encountered in the ACH, using a high technology simulator and standardized patient. A multidisciplinary observer group was given debriefing forms listing the objectives, critical actions, and specific areas to focus their attention. These forms were compiled for data collection.

Results:

Logistical, operational, and patient safety issues were identified during the simulation and compiled into a simulation event report. Proposed solutions and protocol changes were made in response to the identified issues.

Conclusion:

Simulation was successfully used for systems testing, supporting efforts to maximize patient care and provider safety in a rapidly developed ACH. The simulation event report identified operational deficiencies and safety concerns directly resulting in equipment modifications and protocol changes.

Published: March 2021

Objective:

In this work, in order to establish a better comprehension of the association between Argentina and its neighbor countries’ capacity, and COVID-19 burden during the first 3 months, different indicators were evaluated.

Method:

We analyzed the association between GHSI, INFORM index and COVID-19 burden (number of confirmed cases and deaths), also the number of tests, lethality and the stringency of Governmental policies were evaluated.

Results:

Uruguay, Paraguay, and Bolivia started earlier different prevention measures. The number of tests differs, as Chile is the 1 that makes more. Uruguay and Paraguay register fewer positive cases and deaths from COVID-19. The GHS index is led by Brazil, followed by Argentina, and then Chile. However, the INFORM index is led by Uruguay followed by Argentina, while Chile and Paraguay are on par.

Conclusion:

The countries that took preventive measures earlier and carried out a more tests are the ones that are obtaining the best results against COVID-19.
APOCALYPTIC HOMOPHOBIA: FREEDOM OF RELIGIOUS EXPRESSION, HATE SPEECH, AND THE PENTECOSTAL DISCOURSE ON SAME-SEX RELATIONS IN AFRICA
Authors: Ukah Asonzeh
Published: March 2021

In many African societies, gender roles and sexuality are intensely scrutinized, policed, and often enforced. Frequently, this situation results in perceived deviations being characterized in very strong terms. Many Africans across religious and denominational boundaries seem united in their opposition and criticism of same-sex relationships. In the twenty-first century, criminalization of same-sex relationships has witnessed an uptick across the continent. In Nigeria, same-sex union was criminalized in 2014, an act that witnessed massive support from Protestant, especially Pentecostal, Christian communities. Prominent Pentecostal leaders spearheaded the campaign in support and defense of the anti-gay laws in the country. Reasoned opposition to a practice based on religious faith, doctrine, and scriptural prescriptions is an integral aspect of the protection for the practice of religion. However, there is a palpable tension in the debates around rights to free sexual expression as a fundamental element of legally protected human rights and the equally constitutionally embedded right to religious practice, expression, and exercise. At what point, therefore, does the respect for the free exercise of religion and religious expression come into conflict with the respect for, and protection of, minority rights such as claimed rights to sexual expression such as many LGBTQI persons are increasingly contesting? Framed differently, is the verbal and non-verbal promotion of hatred, violence, indignity, and insult or giving offence to a segment of the population based on sexual orientation a part of free religious expression? How do the Pentecostal arguments against same-sex relations in Nigeria approximate to hate speech, defined as a verbal attack on a person or group of persons based on their attributes such as gender and sexual orientation, religion, or ethnicity? To analyze these and related issues, this essay examines the arguments used by the leader of the largest Pentecostal organization in Nigeria—and by far, the most important Pentecostal voice in the country—in the wake of the legal prohibition of homosexuality in Nigeria in 2014.
A Reversal of Fortune: Problematical Deposit 50, Tikal, Guatemala
Authors: Moholy-Nagy Hattula
Published: March 2021

The contents, context, and date of Problematical Deposit 50 bear on the origin, function, and meaning of Teotihuacan stylistic traits in the Southern Maya Lowlands. Archaeological data and material culture research appear to support emulation and adaptation by local rulers and elites, while an actual presence of Teotihuacanos is asserted by epigraphy and iconography. PD 50, the partial contents of a probable Early Classic chamber burial, appears to support local emulation, but an extraordinary pottery vessel, nicknamed here the “Arrival Bowl,” implies direct contact. The chronology and archaeological context demonstrate that the appearance of Teotihuacan stylistic traits at Tikal during the later Early Classic period is functionally distinct from the goods distributed over an interregional interaction sphere of much longer duration in which both Central Mexico and the Maya area participated. Furthermore, together with other features at Tikal, PD 50 suggests that adoption of Teotihuacan ideology by Tikal's elite was eventually met with resistance that contributed to the violence at the end of the Early Classic period that is manifested in the archaeological record.
Ethnic Hatred and Universal Benevolence: Ethnicity and Loyalty in Precolonial Myanmar, and Britain
Authors: Lieberman Victor
Published: March 2021

Insisting on a radical divide between post-1750 ideologies in Europe and earlier political thought in both Europe and Asia, modernist scholars of nationalism have called attention, quite justifiably, to European nationalisms’ unique focus on popular sovereignty, legal equality, territorial fixity, and the primacy of secular over universal religious loyalties. Yet this essay argues that nationalism also shared basic developmental and expressive features with political thought in pre-1750 Europe as well as in rimland—that is to say outlying—sectors of Asia. Polities in Western Europe and rimland Asia were all protected against Inner Asian occupation, all enjoyed relatively cohesive local geographies, and all experienced economic and social pressures to integration that were not only sustained but surprisingly synchronized throughout the second millennium. In Western Europe and rimland Asia each major state came to identify with a named ethnicity, specific artifacts became badges of inclusion, and central ethnicity expanded and grew more standardized. Using Myanmar and pre-1750 England/Britain as case studies, this essay reconstructs these centuries-long similarities in process and form between “political ethnicity,” on the one hand, and modern nationalism, on the other. Finally, however, this essay explores cultural and material answers to the obvious question: if political ethnicities in Myanmar and pre-1750 England/Britain were indeed comparable, why did the latter realm alone generate recognizable expressions of nationalism? As such, this essay both strengthens and weakens claims for European exceptionalism.
Reconnecting Language and Materiality in Christian Reading: A Comparative Analysis of Two Groups of Protestant Women
Authors: Halvorson Britt , Hovland Ingie
Published: March 2021

What do Christians do when they read? How can Christian reading be understood anthropologically? Anthropologists of Christianity have offered many ethnographic descriptions of the interplay among people, words, and material objects across Christian groups, but descriptions of Christian reading have often posited an androgynous reader. In response to this we begin from the observation that while reading cannot be done without words, it also cannot be done without a body. We propose that an analytic approach of placing language and materiality (including bodies) together will help clarify that reading texts is an embodied practice, while not undermining the importance of working with words. We draw inspiration from the recent interest in bringing linguistic anthropology and materiality studies together into the same analytic frame of “language materiality.” We explore a language-materiality approach to reading by comparing how the biblical story of Mary and Martha was read by Protestant women in two historical situations: 1920s Norway and the 1950s United States. We argue that in these cases the readers’ gendered, raced, and classed bodies were central to the activity of reading texts, including their bodies’ material engagements with the world, such as carrying out women's work. We suggest that paying attention to embodied reading—that is, readers’ social entanglements with both language and materiality—yields a fuller analysis of what reading is in particular historical situations, and ultimately questions the notion of a singular Protestant semiotic ideology that works consistently toward purification.
Muslim-Jewish Sexual Liaisons Remembered and Imagined in 20th-Century Yemen
Authors: Wagner Mark S.
Published: March 2021

Despite mutual taboos against exogamy, memoirs and similar materials written by Jews from Yemen contain a number of anecdotes describing love affairs and sexual encounters between Muslims and Jews prior to the mass migration of the vast majority of Yemen's Jews to Israel in 1949–50. These stories associate these liaisons with vulnerability, poverty, and marginalization. In them, sex and conversion to Islam are intrinsically connected, yet this interreligious intimacy leads not to resolution but to ongoing identity crises that persist beyond the community's realignment with a majority-Jewish society. The staging of the anecdotes in rural areas where shariʿa norms held only nominal sway, in watering places and hostels where strangers might interact, and at dusk, when identity is difficult to discern, heightened their ambiguity.
Shelter/housing options, supports and interventions for older people experiencing homelessness

While experiences of later-life homelessness are known to vary, classification of shelter, housing and service models that meet the diverse needs of older people with experiences of homelessness (OPEH) are limited. To address this gap, a scoping review was conducted of shelter/housing options, supports and interventions for OPEH. Fourteen databases were searched for English-language peer-reviewed and/or empirical literature published between 1999 and 2019, resulting in the inclusion of 22 sources. Through a collaborative, iterative process of reading, discussing and coding, data extracted from the studies were organised into six models: (1) long-term care, (2) permanent supportive housing (PSH), including PSH delivered through Housing First, (3) supported housing, (4) transitional housing, (5) emergency shelter settings with health and social supports, and (6) case management and outreach. Programme descriptions and OPEH outcomes are described and contribute to our understanding that multiple shelter/housing options are needed to support diverse OPEH. The categorised models are considered alongside existing ‘ageing in place’ research, which largely focuses on older adults who are housed. Through extending discussions of ageing in the ‘right’ place to diverse OPEH, additional considerations are offered. Future research should explore distinct sub-populations of OPEH and how individual-level supports for ageing in place must attend to mezzo- and macro-level systems and policies.
Wireless power charging of drone using vision-based navigation
Authors: Anumula Swarnalatha , Ganesan Anitha
Published: March 2021

For more efficient aerial surveillance, charging pads are set up at corresponding distances so that an unmanned aerial vehicle (UAV) can sustain its operations without landing. Usually manual intervention is required to land a UAV for charging and so extend its mission. To enable a UAV to operate autonomously, wireless power charging using inductive coupling is proposed. Using this method, the UAV's battery is charged until it reaches the next charging station. This paper focuses on two significant aspects of the process: vision-based navigation for charging pad detection, and wireless power charging. The coils were designed, and other parameters like mutual inductance, coupling coefficient and the distance between the coils for effective power transmission were analysed, using Ansys and Maxwell software. A quadcopter was built, with battery and Lidar sensor connected to the Arduino controller for low battery voltage detection and height measurement, respectively. Whenever the battery voltage is low, the UAV is steered towards the nearest charging pad using the global position navigation system. To test the process, the quadcopter was flown over the charging pad using a vision-based algorithm pre-defined in the image processor (Raspberry Pi B+).

Control of the novel COronaVIrus Disease-2019 (COVID-19) in a hospital setting is a priority. A COVID-19-infected surgeon performed surgical activities before being tested. An exposure risk classification was applied to the identified exposed subjects and high- and medium-risk contacts underwent active symptom monitoring for 14 days at home. All healthcare professionals (HCPs) were tested for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) at the end of the quarantine and serological tests were performed. Three household contacts and 20 HCPs were identified as high- or medium-risk contacts and underwent a 14-day quarantine. Fourteen HCPs and 19 patients were instead classified as low risk. All the contacts remained asymptomatic and all HCPs tested negative for SARS-CoV-2. About 25–28 days after their last exposure, HCPs underwent serological testing and two of them had positive IgM but negative confirmatory swabs. In a low COVID-19 burden area, the in-hospital transmission of SARS-CoV-2 from an infectious doctor did not occur and, despite multiple and frequent contacts, a hospital outbreak was avoided. This may be linked to the adoption of specific recommendations and to the use of standard personal protective equipment by HCPs.

Adolescent risk for self-injurious thoughts and behaviors (STBs) involves disturbance across multiple systems (e.g., affective valence, arousal regulatory, cognitive and social processes). However, research integrating information across these systems is lacking. Utilizing a multiple-levels-of-analysis approach, this person-centered study identified psychobiological stress response profiles and linked them to cognitive processes, interpersonal behaviors, and STBs. At baseline, adolescent girls (N = 241, Mage = 14.68 years, Range = 12–17) at risk for STBs completed the Trier Social Stress Test (TSST), questionnaires, and STB interviews. Positive affect (PA), negative affect (NA), and salivary cortisol (SC) were assessed before and after the TSST. STBs were assessed again during 3, 6, and 9 month follow-up interviews. Multitrajectory modeling of girls’ PA, NA, and SC revealed four profiles, which were compared on cognitive and behavioral correlates as well as STB outcomes. Relative to normative, girls in the affective distress, hyperresponsive, and hyporesponsive subgroups were more likely to report negative cognitive style (all three groups) and excessive reassurance seeking (hyporesponsive only) at baseline, as well as nonsuicidal self-injury (all three groups) and suicidal ideation and attempt (hyporesponsive only) at follow-up. Girls’ close friendship characteristics moderated several profile–STB links. A synthesis of the findings is presented alongside implications for person-centered tailoring of intervention efforts.
A Problem of Self-Ownership for Reproductive Justice
Authors: LANPHIER ELIZABETH
Published: March 2021

This paper raises three concerns regarding self-ownership rhetoric to describe autonomy within healthcare in general and reproductive justice in specific. First, private property and the notion of “ownership” embedded in “self-ownership,” rely on and replicate historical injustices related to the initial acquisition of property. Second, not all individuals are recognized as selves with equal access to self-ownership. Third, self-ownership only justifies negative liberties. To fully protect healthcare access and reproductive care in specific, we must also be able to make claims on others to respect, protect, and fulfill our positive rights. As much as nondomination remains an urgent demand for reproductive rights, it does not go far enough to ensure reproductive justice.
