Zusammenfassung
Hintergrund
Psychische Belastungen von Anästhesisten und Intensivmedizinern sind vielfältig und komplex. Overcommitment (OC) ist durch eine übersteigerte berufliche Verausgabungsneigung gekennzeichnet, die zu psychischen Beanspruchungsfolgen wie z. B. Burnout führen kann. Die Prävalenz von Burnout bei Intensivmedizinern ist international weit gestreut. Ziel der Studie war es, Verausgabungen und Gratifikationen bei ukrainischen Ärzten der Anästhesie und Intensivmedizin während der SARS-CoV-2-Pandemie zu ermitteln und zu analysieren, wie hoch das Burnout-Risiko in dieser Berufsgruppe ist und welche Assoziationen zwischen der intrinsischen Komponente und der extrinsischen Komponente des Modells der beruflichen Gratifikationskrise und dem Burnout bestehen.

Methodik
An der Querschnittsstudie mit der konfirmatorischen Fragestellung im März 2021 nahmen 73 ukrainische intensivmedizinisch tätige Ärzte (47,9 %) und Ärztinnen (52,1 %) teil. Das mittlere Alter lag bei 39,8 ± 10,94 Jahren (Range: 23–78 Jahre). Neben soziodemografischen und berufsbezogenen Daten wurden die berufliche Gratifikation mittels Effort-reward-Imbalance-Fragebogen (ERI) einschließlich der OC-Fragen und das Maslach Burnout Inventory (MBI) erhoben. Die Teilnehmenden der Befragung wurden in Gruppen mit unterschiedlichem OC (< 16 Punkte) und (≥ 16 Punkte) eingestuft und verglichen.

Ergebnisse
In die Gruppe mit OC < 16 Punkte konnten 75 % (55) Teilnehmende eingestuft werden, 18 boten ein erhöhtes OC. Zwischen diesen beiden Gruppen fand sich eine signifikante Differenz im Effort (13,9 ± 4,1 vs. 17,2 ± 3,6 Punkte; p = 0,003) und in der ERI-Ratio (0,58 ± 0,2 vs. 0,77 ± 0,2; p = 0,006). In der Gruppe mit OC ≥ 16 waren 50 % der Teilnehmenden mit einer hohen emotionalen Erschöpfung (vs. 12,7 % bei OC < 16; p = 0,002), aber auch 61,1 % mit einer hohen Leistungsfähigkeit (61,1 % vs. 32,7 %; p = 0,005). Insgesamt konnte eine Burnout-Prävalenz von 2,7 % in der Gesamtstichprobe festgestellt werden, wobei die beiden Probanden bei der Gruppe mit OC < 16 vertreten waren. Die höhere emotionale Erschöpfung war mit einer höheren Verausgabungsneigung und Verausgabung (Effort) sowie einer geringeren Belohnung (Reward) assoziiert.

Diskussion
Die Studienergebnisse zeigten hohe emotionale Erschöpfung bei Personen mit hohem Overcommitment. Drei Viertel der Befragten zeigten Burnout-Symptome. Aus diesem Grund sollten Gesundheitsförderungsmaßnahmen und Prävention angeboten werden, um den hohen Belastungen während der Pandemie entgegenzuwirken. Diese sollten Verhältnis- und Verhaltensprävention einschließen.
Student Understanding of the Sign of Negative Definite Integrals in Mathematics and Physics

Published: January 2023

AbstractIn a study of student understanding of negative definite integrals at two institutions, we administered a written survey and follow-up clinical interviews at one institution and found that “backward integrals”, where the integral was taken from right to left on the x-axis, were the most difficult for students to interpret. We then conducted additional interviews focused on backward integrals at a second institution. Our analysis uses the concept image framework and a recent categorical framework for mathematical sense making. We found that students were most successful using the Fundamental Theorem of Calculus to determine the sign of an integral when a symbolic expression was provided. When considering a definite integral in a graphical context, students often had difficulty if they viewed the integral as a spatial area, stating that area must always be positive. Some students were able to conceptualize $$\Delta x$$

Δ
x

or $$dx$$

dx

as a difference or change and thus a signed quantity; when these students were able to view the area as a sum of smaller pieces, they were more successful in justifying a negative backward integral. Students who used amounts or similar images often had difficulty making sense of the negative sign. Even more progress was made when students either invoked or were asked explicitly about a specific physical context to be represented by the backward integral, other than spatial area. The context provided a meaning to the difference represented by $$\Delta x$$

Δ
x

or $$dx$$

dx

and thus to the sign of that difference and the definite integral.
Distance education as a tool to improve researchers’ knowledge on predatory journals in countries with limited resources: the Moroccan experience

AbstractThe emergence of predatory journals is a global threat for scientific integrity, particularly in under-resourced settings such as low- and middle-income countries (LMICs). A bilingual course on predatory publishing using a distance education approach was developed for Moroccan researchers as a response to the imperative need for training on research ethics to implement good scientific practices. A cross-sectional survey-based study was conducted to evaluate outcomes after delivering two education sessions in both French and English. Before this course, 40% of participants indicated that they don’t verify journal quality before manuscript submission and most of them consider Scopus indexing and the impact factor as the best criteria for journal publication. Approximately 50% of surveyees did not have previous information on predatory journals before the webinar. Pressure to publish by supervisors, institutions of affiliation, or funding agencies, was noticed in 43.4% of participants. After the webinar course was delivered, remarkably, the proportion of participants with knowledge on predatory publishing was meaningfully increased from 48.9% to 81%. Importantly, 83.7% of participants indicated that they are motivated to share their new knowledge on predatory publishing with their colleagues. Moreover, the majority of respondents (73.8%) reported that publishing their research in predatory journals may damage their career and professional future. Promisingly, nearly a half or more of participants recommended the use of training based on distance education, surveillance of researchers by their mentors and affiliations, and social networks to increase awareness on predatory publishing. Almost all participants were satisfied with the content of the webinar. Trainers and research institutions in LMICs should benefit from the advent of distance education using webinar platforms to increase awareness on the issue of predatory publishing in their settings.

Urban planners’ perspectives of public participation in planning in Nigeria
Authors: Echendu Adaku Jane 
Published: January 2023

AbstractPublic/community participation is globally recognized today as an integral aspect of urban planning. This is evident in various international, national, and local planning standards, regulations, and policies. This is no different in Nigeria where the various national and state level planning regulations incorporate this integral part of planning. This study investigates the extent of public participation in planning in Rivers State, Nigeria. Urban planners working in Rivers State were interviewed and academic papers on public participation in planning reviewed. This work finds that despite the mandatory legal provision for public inclusion in the planning process, it is largely not implemented in practice in the formal planning process. The lack of public participation in the planning process is a major reason for poor public support of plans which impacts successful execution. For Nigeria to achieve goals of having sustainable and vibrant urban communities, it is essential to begin implementing the planning laws which mandates public participation by meaningfully involving the public in urban planning processes. This will ensure a broader acceptance and instil a feeling of ownership of plans and processes among citizens which will enhance sustainable planning and development.
Wear Performance of a Novel Silicon Nitride Ceramic for Biomedical Applications
Authors: Correa Filho Luimar , Fu Le , Engqvist Håkan , Xia Wei , Persson Cecilia 
Published: January 2023

AbstractCeramic materials are sometimes used as bearing surfaces of joint implants due to their high wear resistance and biocompatibility. Silicon nitride (Si3N4) is one of the ceramics under investigation for such use, owing to its bacteriostatic properties and high wear resistance. Traditional Si3N4 is sintered using Al2O3 and Y2O3 as sintering aids. To improve the biocompatibility and bioactivity of Si3N4, new sintering aids (SrO, MgO, and SiO2) were used in this work. This substitution may however have substantial effects on the wear properties of the material. Hence, the aim of this study was to evaluate these effects. Multidirectional pin-on-disc wear tests against ultra-high molecular weight polyethylene pins were used to this end, running in fetal bovine serum solution at 37 °C for 2 million cycles. The surface roughness, phase composition, and surface morphology of the surfaces were investigated, together with the pH of the wear test lubricant and compared to a traditional Si3N4 composition. XRD and SEM results showed that the prepared ceramics were composed of α- and β-phase Si3N4. The surface roughness of the Si3N4 ceramic discs was in accordance with the biomedical standard, and the wear test results demonstrated that the new ceramics had a low wear factor and a comparable coefficient of friction to Si3N4 ceramics reported in previous work. However, the dissolution of the materials over time may be a concern for biotribological applications, such as long-term use or in other wear couples.

Abstract

Background:
Compared to the general population, individuals incarcerated in jails and prisons are more vulnerable to infection and mortality from communicable diseases, such as COVID-19 and influenza. However, vaccination rates among incarcerated individuals as well as staff who work in jails and prisons remain disproportionately low. Healthcare administrators working in jails have first-hand experience about barriers to vaccine provision, but their perspectives are infrequently collected and analyzed.

Methods:
We reached out to Health Services Administrators (HSAs) from all 14 Massachusetts (MA) county jails for qualitative in-depth interviews to understand how their personal and professional feelings about vaccination relate to the barriers and facilitators that surround administration of vaccines in jail.

Results:
Eight people participated in the study (8/14 = 57% response rate). Key themes emerged, including 1) HSAs expressed divergent opinions on incarceration as the correct opportunity to vaccinate individuals, 2) HSAs’ personal views on vaccines influenced their operationalization of vaccination in jail, and 3) opinions varied on whether their institutions’ vaccine protocols needed modification.

Conclusions:
Our findings highlight the critical need to leverage the feedback and influence of stakeholders such as HSAs in efforts to improve preventative healthcare delivery in carceral health systems.
Phenologies of Canada thistle (Cirsium arvense) andCirsiumspecies native to the upper Midwest: implications for the ecological host range of the biocontrol agentHadroplontus litura

Published: January 2023

AbstractNativeCirsiumspecies play an important role in landscapes across North America.Hadroplontus litura(F.) (formerlyCeutorhynchus litura), the stem-mining weevil and biological control agent of Canada thistle [Cirsium arvense(L.) Scop.] can complete its life cycle on fiveCirsiumspecies native to the upper Midwest. Although these fiveCirsiumspecies are within the fundamental host range ofH. litura, as determined by host-range tests, we wanted to explore whether phenological differences amongCirsiumspecies help define the field ecological host range ofH. litura. The objective of this study was to determine the phenology ofCirsiumspecies native to the upper Midwest in relation toC. arvenseandH. litura.Our goal was to explore whether shoots of nativeCirsiumspecies could escapeH. liturashoot oviposition in spring due to delayed shoot emergence relative toC. arvense. Soil cumulative growing degree days (GDD) were a superior predictor of shoot emergence for perennialCirsiumspecies or initiation of leaves in biennialCirsiumspecies, with a 2.4 times larger effect on time to emergence relative to air GDD. All nativeCirsiumspecies initiated new leaves or shoots beforeC. arvenseshoot emergence, even when nativeCirsiumspecies growth was delayed in the spring. In turn,C. arvenseshoots emerged approximately 1 to 3 wk before femaleH. liturabegan to lay eggs. As such, all nativeCirsiumplants had shoots available forH. lituraoviposition. There was no phenological separation between nativeCirsiumandC. arvenseshoot emergence or initiation that would render nativeCirsiumspecies safe fromH. lituraattack. Based on the phenology of shoot emergence or initiation in the spring, all testedCirsiumspecies native to the upper Midwest would be within the ecological host range ofH. litura.

Published: January 2023

AbstractThere is limited documentation of cross-tenure collaborative weed management programs, and no consistent set of metrics for evaluating their performance. In this study, 12 weed management practitioners in southeast Australia participated in a qualitative social research project to discuss and document examples of cross-tenure collaborative weed management and critically reflect on whether existing metrics are suitable for evaluating the performance of their programs. Analysis of focus group discussions, project documentation, subsequent reflections, and review of the literature reveal that weed management practitioners, in Australia and elsewhere, mostly rely on metrics that measure weed management inputs, such as herbicides, labor, and costs. Metrics used to evaluate social outcomes focus on benefits for individuals rather than social relationships or achievement of equitable outcomes. Social research on collaborative governance and social science methods more broadly, such as social network analysis and collective narratives, could be used by weed management practitioners to better evaluate and explain social–ecological outcomes over time.
Preferential attachment hypergraph with high modularity

Published: January 2023

AbstractNumerous works have been proposed to generate random graphs preserving the same properties as real-life large-scale networks. However, many real networks are better represented by hypergraphs. Few models for generating random hypergraphs exist, and also, just a few models allow to both preserve a power-law degree distribution and a high modularity indicating the presence of communities. We present a dynamic preferential attachment hypergraph model which features partition into communities. We prove that its degree distribution follows a power-law, and we give theoretical lower bounds for its modularity. We compare its characteristics with a real-life co-authorship network and show that our model achieves good performances. We believe that our hypergraph model will be an interesting tool that may be used in many research domains in order to reflect better real-life phenomena.
You were bombed and now you have to pay for it: Questioning the positive obligations in the Treaty on the Prohibition of Nuclear Weapons
Authors: Hood Anna 
Published: January 2023

AbstractOne of the central components of the Treaty on the Prohibition of Nuclear Weapons (TPNW) is its victim assistance and environmental remediation provisions (known collectively as the Treaty’s ‘positive obligations’). While there is much to celebrate about efforts to remedy the damage caused by nuclear weapons, the way the TPNW distributes responsibility for this work is troubling. Under the Treaty, the primary responsibility for fulfilling the positive obligations is placed on the states parties that have individuals under their jurisdiction who are affected by the use or testing of nuclear weapons and areas under their jurisdiction or control that have been contaminated by the use or testing of nuclear weapons (‘the affected states’) despite the fact that, often, these were not the states responsible for detonating the nuclear weapons. This article examines and critiques the reasons the Treaty’s drafters placed the main responsibility for victim assistance and environmental remediation on affected states. It argues that the rationales underpinning these provisions rest on shaky grounds, and that the Treaty’s approach has potential negative ramifications for nuclear disarmament and understanding the history of the use and testing of nuclear weapons. Further, it explores how the Treaty may play into worrying broader dynamics in public international law whereby the Global North is frequently absolved of responsibility for the harms it causes while the Global South is saddled with obligations to redress an array of harms.
Selling lowbrow art and cultural goods in times of pandemic: The case of a provincial art market
Authors: Radermecker Anne-Sophie 
Published: January 2023

AbstractThis article examines the impact of the coronavirus pandemic on a provincial art market to shed light on how gallerists, auctioneers, and antique dealers have coped with this exogenous event. Provincial intermediaries, active in the lower ends of the art market, are characterized by economic properties that differ from those of the upper-end markets. Their location at the periphery of metropolitan centers, combined with the characteristics of supply and demand, are likely to affect their ability to face a global crisis. Based on 15 semi-structured interviews with provincial intermediaries, this research reveals the unexpected performance of local auction houses and antique dealers active in the secondary art market. We attribute this performance to the use value of lowbrow cultural goods, the willingness of local auction houses to embrace the benefits of online two-sided markets, and their ability to offset a pent-up demand, especially among Generation Y. Recommendations to prompt provincial art market players to sustain the positive externalities of the crisis in the long run are provided.
On Interpretation and Appreciation. A European Human Rights Perspective on Dobbs
Authors: Buijsen Martin 
Published: January 2023

AbstractIn June 2022, the Supreme Court of the United States overturned Roe v. Wade. The European Court of Human Rights is also expected to decide on several abortion cases. In this paper, the interpretative approaches of both courts are compared. Whereas the U.S. Supreme Court in Dobbs v. Jackson Women’s Health Organization decided on an originalist approach to the Constitution, the highest European court has always regarded the European Convention on Human Rights as a living instrument. As a result, domestic laws regulating the interruption of pregnancy are seen by the Strasbourg court as interferences with a fundamental right, the right to respect for private life. Although member states of the Council of Europe enjoy a wide margin of appreciation with regard to the circumstances in which abortion will be permitted, its highest court put forward the state’s positive obligation to secure pregnant women’s right to effective respect for their physical and psychological integrity in several landmark judgments. In this way, it ensures the existence of effective mechanisms in countries with a poor record of implementing the right to a lawful abortion. Albeit at a minimum, the Strasbourg court offers protection, whereas the U.S. Supreme Court no longer does.

AbstractObjectives:Cardiac manifestations of the coronavirus disease 2019 (COVID-19) have mainly been reported in adults. Therefore, we aimed to determine the electrocardiographic abnormalities in hospitalised paediatric patients with COVID-19 and multisystemic inflammatory syndrome in children.Methods:We retrospectively evaluated hospitalised paediatric patients <18 years of age with a diagnosis of COVID-19 (n = 168) and multisystem inflammatory syndrome in children (n = 48) between March 2021 and December 2021. A daily electrocardiography was performed for the patients who had electrocardiographic abnormalities on admission or developed electrocardiographic abnormality on the follow-up. The characteristics of these patients, underlying predisposing conditions, and clinical course were also examined.Results:Two-hundred sixteen paediatric patients (55% were male) with a mean age of 10.7 ± 4.69 years were evaluated. There was an underlying disease in 84 (38.8%) patients and 51 (23.6%) required paediatric ICU admission. Electrocardiography abnormality was detected in 12 (5.5%) which were as follows: 7 (3.2%) had sinus bradycardia, 3 (1.4%) patients had transient ST elevation and concomitant T negativity, and 2 (0.9%) developed first-degree Atrioventricular (AV) block. The median time from the onset of disease symptoms to detecting electrocardiographic abnormality was 9 days. Electrocardiographic abnormalities returned to normal uneventfully 3 days later.Conclusions:The prevalence of arrhythmia in paediatric patients with COVID-19 was detected in 5.5% of the patients. While two-thirds of the electrocardiography abnormalities were sinus bradycardia, ST elevation was remarkable (1.4%). Clinicians should be aware of electrocardiographic abnormalities and consider electrocardiographic monitoring in paediatric patients with COVID-19 and multisystemic inflammatory syndrome in children.
