Published: January 2023

AbstractIn low‐income urban areas of major cities in Africa, sanitation provision derives primarily from onsite systems often comprising septic tanks and pit latrines. Such systems rely upon the ability of the surrounding soil and substratum to attenuate contaminants like nitrate and pathogenic microorganisms in wastewater. Here, we assess soil–water and solute dynamics in Quaternary aeolian sands underlying a densely populated suburb (Keur Massar) of Dakar (Senegal) using high‐frequency monitoring and vadose zone modeling (Hydrus‐1D). Observations of rainfall intensity, soil moisture content, and shallow groundwater‐level fluctuations and nitrate concentrations were carried out at an experimental site adjacent to a septic tank supplied by toilets used by a primary school. Rapid rises in soil moisture content and episodic recharge contributions observed in groundwater levels caused by heavy (>10 mm h−1) and extreme (>20 mm h−1) rainfall are well modeled (R2 = .79–.83; RMSE = 0.012–0.019) by pore‐matrix flow in the unsaturated zone by the Darcy–Richards equation. Spot sampling around the most intense rainfall of 2020 (45 mm h−1) reveals a fivefold rise and fall in the concentration of nitrate in soil moisture (∼500 to ∼2,500 mg L−1). These measurements provide new insight into the hydrological dynamics by which shallow groundwater is grossly contaminated (>500 mg L−1) by nitrate through episodic flushing by heavy rainfall of wastewater from a vast estimated network of over 250,000 septic tanks underlying this suburb of Dakar.

AbstractObjectivesInvestigate opioid usage and postoperative pain in patients undergoing head and neck free flap surgery.MethodsA retrospective review of 100 consecutive patients undergoing head and neck free flap reconstruction at two academic centers was performed. Data captured included demographics, postoperative inpatient pain, pain at postoperative visits, morphine equivalent doses (MEDs) administration, medication history, and comorbidities. Data were analyzed using regression models, χ2 tests, and student's t‐tests.ResultsSeventy‐three percent of patients were discharged with opioid medication, with over half (53.4%) continuing to take opioids at their second postoperative visit, and over one‐third (34.2%) continuing to take them around 4‐month postoperatively. One out of every five (20.3%) opioid‐naïve patients chronically took opioids postoperatively. There was a poor association between inpatient postoperative pain scores and daily MEDs administered (R2 = 0.13, 0.17, and 0.22 in postoperative Days 3, 5, and 7, respectively). Neither preoperative radiotherapy nor postoperative complications were associated with an increase in opioid usage.ConclusionsFor patients undergoing head and neck free flap operations, opioid medications are commonly used for postoperative analgesia. This practice may increase the chance an opioid‐naïve patient uses opioids chronically. We found a poor association between MEDs administered and patient‐reported pain scores, which suggests that standardized protocols aimed at optimizing analgesia while reducing opioid administration may be warranted.Level of Evidence: 3 (Retrospective cohort study).
Zarte Hände bringen Erleichterung. Thure-Brandt-Massage als Zeitdokument und Gründungshilfe für die Urologie
Authors: Mildenberger Florian G. , Moll Friedrich H. 
Published: January 2023

ZusammenfassungNaturheilkunde und Urologie berühren sich in der Gegenwart kaum, aber im viktorianischen Zeitalter war es eine Genitalmassage, die der Ärzteschaft verdeutlichte, dass eine auf die Erkrankungen des Unterleibs spezialisierte Ausbildung für Ärzte notwendig war, da ansonsten die Patientinnen Laienheilkundige aufsuchen würden und keine Kliniken. Diese Massage war von dem schwedischen Offizier Thure Brandt in den 1850er-Jahren entwickelt worden. Sie blieb bis nach dem Zweiten Weltkrieg ein Thema in deutschen Arztpraxen.

Published: January 2023

AbstractBuyang Huanwu decoction, a classic traditional Chinese prescription, has been used to prevent and treat stroke for hundreds of years. An increasing number of the laboratory research on Buyang Huanwu decoction used in treating cerebral ischemia–reperfusion injury have been published recently. However, the problem of methodological and reporting quality of some studies is lack of assessment. This study aims to evaluate the methodological and reporting quality of the research on Buyang Huanwu decoction against experimental cerebral ischemia–reperfusion injury. A comprehensive search on six databases was performed. Two researchers independently screened the literature considering the eligibility criteria. Methodological and reporting quality of the included studies were evaluated by the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) risk-of-bias tool and Animal Research: Reporting of In Vivo Experiments (ARRIVE) guideline. Forty-five studies met the inclusion criteria. No study achieved a decent overall rating in using the SYRCLE tool (percentage of items with “low risk” ≥ 50%). Of the 22 items on the SYRCLE tool, only 7 items (31.82%) were rated as “low risk” in more than 50% of the included studies. Of the 39 items of ARRIVE guideline, 14 (35.9%) items were rated as “yes” in more than 50% of the included studies. The methodological and reporting quality of Buyang Huanwu decoction for experimental cerebral ischemia–reperfusion injury was substandard, which needed to be further improved. The limitations should be addressed when planning similar studies in the future. Additionally, these findings provided evidence-based guidance for future preclinical studies evaluating the efficacy of Buyang Huanwu decoction in the treatment of cerebral ischemia–reperfusion injury.
On Approximate and Weak Correlated Equilibria in Constrained Discounted Stochastic Games

Published: January 2023

AbstractIn this paper, we consider constrained discounted stochastic games with a countably generated state space and norm continuous transition probability having a density function. We prove existence of approximate stationary equilibria and stationary weak correlated equilibria. Our results imply the existence of stationary Nash equilibrium in ARAT stochastic games.
De Finetti’s Control Problem with Competition
Authors: Ekström Erik , Lindensjö Kristoffer 
Published: January 2023

AbstractWe investigate the effects of competition in a problem of resource extraction from a common source with diffusive dynamics. In the symmetric version with identical extraction rates we provide conditions for the existence of a Nash equilibrium where the strategies are of threshold type, and we characterize the equilibrium threshold. Moreover, we show that increased competition leads to lower extraction thresholds and smaller equilibrium values. For the asymmetric version, where each agent has an individual extraction rate, we provide the existence of an equilibrium in threshold strategies, and we show that the corresponding thresholds are ordered in the same way as the extraction rates.
The VACStent trial: combined treatment of esophageal leaks by covered stent and endoscopic vacuum therapy

Abstract
Background
Endoscopic treatment of esophageal leaks, mostly by covered stents or endoscopic vacuum therapy (EVT), has largely improved the clinical outcome in the last decade. However, both techniques suffer from significant limitations. Covered stents are hampered by a high rate of migration and missing functional drainage, whereas endoluminal EVT devices are limited by obstruction of the GI tract. The new design of the VACStent makes it a fully covered stent within a polyurethane sponge cylinder, allowing EVT while stent passage is still open. Initial clinical applications have demonstrated the fundamental concept of the VACStent.

Method
A prospective multicenter open-label study was performed with the primary endpoint safe practicality, complete leak coverage, and effective suction-treatment of esophageal leaks. Secondary endpoints were prevention of septic conditions, successful leak healing, and complications, in particular stent-migration, local erosions and bleeding.

Results
Fifteen patients with different, mostly postoperative anastomotic leaks were enrolled in three centers. A total of 41 VACStents were implanted. The mean number of VACStents per patient was 2.7, with a mean duration of VACStent treatment of 15 days. The primary endpoint was met in all VACStent applications (41/41 implants), resulting in a leak healing rate of 80% (12/15 patients). Septic episodes were prevented in 93% (14/15 patients) and there was no mortality. There were no severe device-related adverse events (SADE) nor significant local bleeding or erosion. Minor stent-dislocation and migration, respectively, was observed in 7%. Oral intake of liquids or food was documented in 87% (13/15 patients). One anastomotic stenosis was seen during follow-up.

Conclusions
VACStent treatment is a safe and effective treatment in esophageal leaks which can be covered by the sponge cylinder. Its application was described as easy and resembling that of conventional GI stents, with an impressive clinical success rate comparable to EVT outcomes. The VACStent offers a new option for clinical treatment of critical situations in esophageal perforations and anastomotic sutureline failures.
Ecological regulation for healthy and sustainable food systems: responding to the global rise of ultra-processed foods
Authors: Northcott Tanita , Lawrence Mark , Parker Christine , Baker Phillip 
Published: January 2023

AbstractMany are calling for transformative food systems changes to promote population and planetary health. Yet there is a lack of research that considers whether current food policy frameworks and regulatory approaches are suited to tackle whole of food systems challenges. One such challenge is responding to the rise of ultra-processed foods (UPF) in human diets, and the related harms to population and planetary health. This paper presents a narrative review and synthesis of academic articles and international reports to critically examine whether current food policy frameworks and regulatory approaches are sufficiently equipped to drive the transformative food systems changes needed to halt the rise of UPFs, reduce consumption and minimise harm. We draw on systems science approaches to conceptualise the UPF problem as an emergent property of complex adaptive food systems shaped by capitalist values and logics. Our findings reveal that current food policy frameworks often adjust or reform isolated aspects of food systems (e.g., prices, labels, food composition), but under-emphasise the deeper paradigms, goals and structures that underlie the rise of UPFs as a systems phenomenon, and its socio-ecological implications. We propose that a ‘leverage points’ framework illuminateswhereto intervene in food systems to generate multi-level changes, while the theory of ecological regulation highlightshowto respond to complex multi-factorial problems, like the rise of UPFs, in diverse ways that respect planetary boundaries. More research is needed to better understand the transformative potential of ecological regulation to advance food systems transformation and attenuate whole of food systems challenges.
Testing time evolution of mass distribution of black hole mergers
Authors: Suyama Teruaki , Okano So 
Published: January 2023

AbstractThe detection of gravitational-wave events revealed that there are numerous populations of black hole (BH) binaries that can merge within the age of the Universe. Although several formation channels of such binaries are known, considerable theoretical uncertainties associated with each channel defeat the robust prediction of how much each channel contributes to the total merger rate density. Given that the time evolution of the merger rate density in some channels is (exactly or nearly) independent of BH masses, clarifying this feature from observational data will shed some light on the nature of BH binaries. On the basis of this motivation, we formulate a methodology to perform a statistical test of whether the mass distribution of BH mergers evolves over time by hypothesis testing. Our statistical test requires neither a priori specification of the mass distribution, which is largely uncertain, nor that of the time dependence of merger rate. We then apply it to mock data for some concrete shapes of the merger rate density and show that the proposed method rejects/(does not reject) the null hypothesis correctly for a large sample size. After this verification, the method is applied to a catalog of the gravitational-wave events obtained during the LIGO-Virgo’s third observing run. We find that the selection bias degrades the effectiveness of our method for the O3 catalog owing to the reduction in the number of and the maximum redshifts of the merger events that we can explore. Within the range where the method can be applied, there is no indication of the time evolution of the mass distribution of merger rate density. This limitation will be eased in future observations containing more events, and our hypothesis testing will help determine whether the merger rate density evolves over time independently of BH masses.
Hate in the time of the Covid-19 pandemic: dehumanisation as a side effect; re-humanisation as a remedy
Authors: Collard Melanie 
Published: January 2023

AbstractThis article is about denouncing the dehumanisation process that took place in the time of Covid-19. It recognises that governments have a vital role to play in setting national directions to tackle racist violence and that the value of having hate crime laws should not be underestimated. However, it argues that a broader approach is needed to embark upon are-humanisation initiative and effectively combat racist violence. It emphasises that, to get people truly devoted to a course of action, they must develop a greater understanding of the sources of the problem. Accordingly, this article suggests that academia has a key role to play in shedding light on the occurrence ofde-humanisation and the potential forre-humanisation.
Evaluating state-of-the-art # SAT solvers on industrial configuration spaces

Published: January 2023

AbstractProduct lines are widely used to manage families of products that share a common base of features. Typically, not every combination (configuration) of features is valid. Feature models are a de facto standard to specify valid configurations and allow standardized analyses on the variability of the underlying system. A large variety of such analyses depends on computing the number of valid configurations. To analyze feature models, they are typically translated to propositional logic. This allows to employ SAT solvers that compute the number of satisfying assignments of the propositional formula translated from a feature model. However, the SAT problem is generally assumed to be even harder than SAT and its scalability when applied to feature models has only been explored sparsely. Our main contribution is an investigation of the performance of off-the-shelf SAT solvers on computing the number of valid configurations for industrial feature models. We empirically evaluate 21 publicly available SAT solvers on 130 feature models from 15 subject systems. Our results indicate that current solvers master a majority of the evaluated systems (13/15) with the fastest solvers requiring less than one second for each successfully evaluated feature model. However, there are two complex systems for which none of the evaluated solvers scales. For the given experiment design, the solvers that consumed the least runtime are (2.5 seconds in sum for the 13 systems) and (3.5 seconds).
The potential of transformative learning for sustainability transitions: moving beyond formal learning environments
Authors: Singer-Brodowski Mandy 
Published: January 2023

AbstractTransformative learning has become one of the most prominent learning theory in regard to sustainable development. It holds enormous potential for explaining and accompanying learning processes related to processes of transformation for sustainability, especially due to its emphasis on changing meaning perspectives in discussions with others in spaces free of coercion. In addition, it inspires learners and educators to pay particular attention to emotional challenges when they engage in critical thinking. This theoretical paper explores the potential of transformative learning theory by examining informal learning environments where people do not explicitly intend to learn but learning happens en passant or incidentally. It shows the ability of transformative learning theory to explain what can happen on the level of individual learning, organizational learning, learning in multi-professional networks, and learning in transdisciplinary or transformative research cooperation processes. Based on this analysis, recommendations can be derived to stimulate, enable, and accompany transformative learning processes for sustainability.
Using Satellite-Based Terrestrial Water Storage Data: A Review
Authors: Humphrey Vincent , Rodell Matthew , Eicker Annette 
Published: January 2023

AbstractLand water storage plays a key role for the Earth’s climate, natural ecosystems, and human activities. Since the launch of the first Gravity Recovery and Climate Experiment (GRACE) mission in 2002, spaceborne observations of changes in terrestrial water storage (TWS) have provided a unique, global perspective on natural and human-induced changes in freshwater resources. Even though they have become much used within the broader Earth system science community, space-based TWS datasets still incorporate important and case-specific limitations which may not always be clear to users not familiar with the underlying processing algorithms. Here, we provide an accessible and illustrated overview of the measurement concept, of the main available data products, and of some frequently encountered technical terms and concepts. We summarize concrete recommendations on how to use TWS data in combination with other hydrological or climatological datasets, and guidance on how to avoid possible pitfalls. Finally, we provide an overview of some of the main applications of GRACE TWS data in the fields of hydrology and climate science. This review is written with the intention of supporting future research and facilitating the use of satellite-based terrestrial water storage datasets in interdisciplinary contexts.
You May Destroy This Village, But You Cannot Destroy the Power Which Created It
Authors: Dézsi Attila 
Published: January 2023

AbstractTo develop a historical archaeology of hope, post-medieval European archaeology should shift the focus beyond dark heritage to sites and events opposed to daily destruction and alienation. This case study of an antinuclear protest camp in 1980s Germany shows that cracks in capitalism formed when people protested for something; as they experimented with alternative lifeways and envisioned an alternative future. Archaeological intervention can help to reveal these fault lines in capitalism as we remember these heritage sites of hope, but intervention also reveals a cautionary tale of how these blurry pictures of an alternative future can so easily be concealed.
The Development of Generativity in Middle Adulthood and the Beginning of Late Adulthood: A Longitudinal Study from Age 42 to 61

Published: January 2023

AbstractPrevious studies have yielded mixed results regarding the development of generativity during adulthood. Longitudinal data were utilized to investigate the average development of generativity between the ages of 42 and 61 as well as individual differences in terms of its development. The study used data from the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS) (initial N = 369). The data consisted of 291 individuals whose generativity scores, measured using the Generativity Scale, were available at age 42, 50, or 61. Rasch analysis was utilized to form a generativity measure. The development of generativity between the measurements was investigated in women and men using Bland–Altman plots and the latent change score model. The results showed that, on average, generativity decreased from age 42 to 61 in women and men; however, there were individual differences in the extent and direction of the change with age. The level of generativity at age 42 predicted the change occurring between ages 42 and 50 and ages 50 and 61. Furthermore, the change between ages 42 and 50 predicted the change occurring between ages 50 and 61. The more positive the baseline value or the earlier occurring change, the more negative the subsequent change. To conclude, despite the mean-level generativity decreases during middle and late adulthood, there was variance across individuals of the same age, who were followed for nearly two decades. The study emphasizes the importance of investigating individual differences in the development of generativity in adulthood.
Effect of electrolyte and carbon material on the electrochemical performance of high-voltage aqueous symmetric supercapacitors
Authors: Gajewska Katarzyna , Moyseowicz Adam , Minta Daria , Gryglewicz Grażyna 
Published: January 2023

AbstractThe energy storage capability of the aqueous supercapacitors is mainly attributed to the relatively low operating voltage of the device, as the thermodynamic decomposition voltage of water is 1.23 V. Therefore, the extension of the working voltage of the aqueous capacitor beyond the electrolyte decomposition limit is an important subject for the development of environmentally friendly energy storage devices. In this study, a commercial activated carbon (AC) and synthesized phosphorus-doped reduced graphene oxide (P-rGO) were used to gain insight into the influence of both textural properties and the surface chemistry on the electrochemical performance of high-voltage aqueous supercapacitors. Materials on the opposite end of the spectrum (highly porous, undoped AC and heteroatom-rich phosphorus-doped reduced graphene oxide with low porosity) were compared in a symmetric cell, operating in a wide voltage window of 2.0 V in 2 M NaClO4electrolyte. Additionally, AC-based cell was tested in 1 M Na2SO4solution to assess the differences in its performance in different sodium-based electrolytes. The obtained results demonstrate that both a porous structure and high contribution of heteroatoms, which improve the hydrophilicity of the electrode, are required to achieve high specific energy density values. However, with increasing current and higher power densities, a developed porous structure is required to maintain good energy storage characteristics. Achieving high operating voltage in the aqueous symmetric full-carbon supercapacitors is a promising energy storage solution. The assembled devices show a good specific energy density of up to 13 Wh kg−1at a power density of 30 W kg−1.Graphical abstract
