AbstractA supervised field trial was conducted to evaluate the dissipation pattern and dietary risk assessment of the pesticides, Solomon (recommended dose, X (63+147 g a.i./ha) and double the recommended dose, 2X (126+294 g a.i./ha)); spirotetramat (X dose: 90 g a.i./ha and 2X dose: 180 g a.i./ha) and indaziflam (X dose: 62.5 g a.i./ha and 2X dose: 125 g a.i./ha) in citrus (mandarin) fruits and cropped soil. Solomon and spirotetramet were applied as foliar spray at the fruit development stage and indaziflam was applied directly on to the weeds. Fruit and soil samples thus collected were extracted using a quick, easy, cheap, effective, rugged, and safe analytical method for residue estimation, which was carried out using Gas Chromatography‐Electron Capture Detector for betacyfluthrin and High‐Performance Liquid Chromatography for all other analytes. Residues of betacyfluthrin reached below the determination level (0.05 mg/kg) after the 3rd and 5th day of treatment at X and 2X dosage while imidacloprid and spirotetramat residues reached below the determination level on the 5th and 7th day, respectively. Residues of indaziflam and its metabolites were not detected in any citrus and soil matrices. Dietary risk assessment calculated as hazard quotient and theoretical maximum dietary intake revealed the safety of the pesticides for human consumption after application of these pesticides on citrus.

Published: May 2023

AbstractPreparing high‐efficiency, durable and low overpotential electrocatalytic materials for oxygen evolution reaction (OER) plays a key role in water electrolysis. At present, electrochemical water separation technology has become the most promising sustainable hydrogen production process. The inherent hysteresis kinetics of oxygen evolution reaction (OER) is the key bottleneck of water electrolysis, which greatly restricts the energy conversion efficiency and practical large‐scale application. Herein, a facile method is developed to synthesize a series of trimetallic (Mo/Ni/Fe) metal‐organic frameworks (MOFs)‐derived carbon nanoparticles (CNPs) with various Fe content, and a Fe‐dependent volcano‐type plot can be drawn out for MoNiFex‐CNPs. The optimized MoNiFe0.4‐CNPs demonstrate superior electrocatalytic performance with a low overpotential of only 227 mV@10 mA cm−2 and excellent durability of 100 h. Its excellent OER performance is attributed to the synergistic effect of Fe/Ni bimetallic regulated by Mo. This work improved the catalytic performance of MOFs in the OER and proposed a new strategy for the structural design of MOFs.
Topological Obstructions
Authors: Jongeneel Wouter , Moulay Emmanuel 
Published: May 2023

AbstractGiven the previous chapters on topology and dynamical system theory, we can now provide a consistent treatment of topological obstructions to stability and stabilization. In particular, we will see how the retraction theory from Sect. 2.2 and the index results due to Bobylev, Krasnosel’skiĭ and Zabreĭko from Sect. 3.5 cover most of the existing results, conceptually. The current chapter focuses on the obstructions themselves and the next chapter highlights potential solutions.
Sterile neutrino dark matter: relativistic freeze-out
Authors: Lebedev Oleg , Toma Takashi 
Published: May 2023

Abstract
Long-lived sterile neutrinos can play the role of dark matter. We consider the possibility that such neutrinos form a thermal bath with a singlet scalar, while not being in thermal equilibrium with the Standard Model fields. Eventually, the neutrino dark matter undergoes freeze-out in the dark sector, which can occur in both non-relativistic and relativistic regimes. To account for the latter possibility, we use the full Fermi-Dirac and Bose-Einstein distribution functions with effective chemical potential in the reaction rate computation. This allows us to study the freeze-out process in detail and also obtain the necessary thermalization conditions. We find that relativistic freeze-out occurs in a relatively small part of the parameter space. In contrast to the standard weakly-interacting-massive-particle (WIMP) scenario, the allowed dark matter masses extend to 104 TeV without conflicting perturbativity.
Resolution of the LHCb ηc anomaly
Authors: Biswal Sudhansu S. , Mishra Sushree S. , Sridhar K. 
Published: May 2023

Abstract
Due to the heavy-quark symmetry of Non-Relativistic Quantum Chromodynamics (NRQCD), the cross-section for the production of ηc can be predicted. This NRQCD prediction when confronted with data from the LHCb is seen to fail miserably. We address this LHCb ηc anomaly in this paper using a new approach called modified NRQCD, an approach that has been shown to work extremely well for studying J/ψ, ψ′ and χc production at the LHC. We show, in the present paper, that the predictions for ηc production agrees very well with LHCb measurements at the three different values of energy that the experiment has presented data for. Modified NRQCD also explains the intriguing agreement of the LHCb ηc data with the colour-singlet prediction. The remarkable agreement of the theoretical predictions with the LHCb data suggests that modified NRQCD is closer to apprehending the true dynamics of quarkonium production.
Emotionalität in der COVID-19-Krisenkommunikation von Behörden und unabhängigen Expert*innen auf Twitter
Authors: Drescher Larissa S. , Roosen Jutta , Aue Katja , Dressel Kerstin , Schär Wiebke , Götz Anne 
Published: May 2023

Zusammenfassung
Hintergrund
Zu Beginn der COVID‑19-Pandemie herrschte in Deutschland große Unsicherheit in der Bevölkerung und bei den für die Krisenkommunikation Verantwortlichen. Ein wesentlicher Teil der Kommunikation von Expert*innen und zuständigen Behörden fand in den sozialen Medien statt, insbesondere auf der Plattform Twitter. Die dort mit der Krisenkommunikation transportierten positiven, negativen und neutralen Sentiments (Emotionen) sind für Deutschland bisher nicht vergleichend untersucht worden.

Ziel der Arbeit
Die Sentiments in Twitter-Meldungen von verschiedenen (Gesundheits‑)Behörden und unabhängigen Expert*innen zu COVID‑19 sollen für das erste Pandemiejahr (01.01.2020–15.01.2021) ausgewertet werden, um eine Wissensgrundlage für die Verbesserung zukünftiger Krisenkommunikation zu schaffen.

Material und Methoden
Von n = 39 Twitter-Akteur*innen (21 Behörden und 18 Expert*innen) flossen n = 8251 Tweets in die Auswertung ein. Diese erfolgte mit dem sog. Lexikonansatz, einer Methode der Social-Media-Analyse. Es wurden deskriptive Statistiken berechnet u. a. zur Bestimmung der durchschnittlichen Polarität der Sentiments und der Häufigkeiten positiv und negativ besetzter Wörter in 3 Phasen der Pandemie.

Ergebnisse und Diskussion
Die Entwicklung der Emotionalität in COVID‑19-Tweets und der Anzahl von Neuinfektionen in Deutschland verlaufen in etwa parallel. Die Analyse zeigt, dass die Polarität der Sentiments bei beiden Akteursgruppen im Durchschnitt negativ ist. Expert*innen twittern im Untersuchungszeitraum deutlich negativer über COVID‑19 als Behörden. Behörden kommunizieren in der zweiten Phase nahe der Neutralitätslinie, also weder ausgeprägt positiv noch negativ.
Bridging the gap between design and manufacturing specifications for non-rigid parts using the influence coefficient method
Authors: Maltauro Mattia , Passarotto Gianluca , Concheri Gianmaria , Meneghello Roberto 
Published: May 2023

AbstractThe manufacturing process may lead non-rigid parts to endure large deformations which could be reduced during assembly. The manufacturing specifications of the single parts should refer to their free state or “as manufactured” state; the functional specifications should instead address the “as assembled” state. Therefore, a functional geometrical inspection requires dedicated fixtures to bring the parts in “as assembled” state. In this paper, through a linearized model that considers fixturing and elastic spring-back, we aim to correlate the functional specification to the manufacturing specifications. The model suggests a hybrid approach called “restricted skin model” that allows to reduce the degrees of freedom considering the form error when relevant. Firstly, the framework is verified in a mono-dimensional test case. Subsequently, it is verified including FEM simulation and actual measurement for two simple assemblies. The results show that the model can correctly interpret the theoretical assembly behaviour for actual applications. The use of the “restricted skin model” approach shows a negligible difference when compared to full FEM simulation with differences of 2.1 · 10−7 mm for traslations and 6.0 · 10−3 deg for rotations. The comparison with actual measurement values showed an error of ±0.2 mm at the assembly features. Furthermore, the linearized model allows a possible real-time application during production that enables to adjust manufacturing specification limits in case of process drifting.

AbstractDuring the Covid-19 pandemic, health agencies worldwide have recommended frequent handwashing and sanitizing. A variety of hand gel products were made available on the market, often with fragrances added to curtail the strong smell of alcohol. Commonly used Citrus fragrances contain volatile aroma constituents and non-volatile oxygen heterocyclic compounds (OHCs), consisting mostly of polymethoxyflavones, coumarins, and furocoumarins. The latter have long been investigated for their phototoxic properties, and their safety as cosmetic product ingredients has been debated recurrently. To this concern, twelve commercial Citrus-scented products were investigated in this study. An extraction method was optimized for thirty-seven OHC compounds, obtaining absolute mean recovery values in the 73.5–116% range with only few milliliters of solvent consumption. Analysis by ultra-high-pressure liquid chromatography with tandem mass spectrometry detection evidenced that three samples did not conform to the labeling requirements for fragrance allergens (coumarin) laid down by the European Union Regulation on Cosmetic Products. The total furocoumarin (FC) content of the samples investigated was in the 0.003–3.7ppm range, with some noteworthy exceptions. Specifically, in two samples, the total FCs were quantified as 89 and 219 ppm, thus exceeding the safe limits recommended up to a factor of 15. Finally, the consistency of the volatile fingerprint attained by gas chromatography allowed drawing conclusions on the authenticity of the Citrus fragrances labeled, and several products did not conform to the information reported on the label concerning the presence of essential oils. Besides the issue of product authenticity, analytical tools and regulatory actions for widespread testing of hand hygiene products are urgent, to protect consumers’ health and safety.

Depression in brain tumor patients—early detection and screening
Authors: Finze Alida , Deleanu Laura , Weiss Christel , Ratliff Miriam , Seiz-Rosenhagen Marcel 
Published: May 2023

Abstract
Background
Depres
sion is reported in up to 90% of cancer patients but to this date, a standardized screening tool for depression specifically modified for patients diagnosed with brain tumors is lacking. Thus, this study aims to develop an adapted screening tool and identify a suitable time slot for screening.

Methods
Sixty-one patients with brain lesions were interviewed prior to neurosurgical resection. For screening purposes, established depression scores were used. A study-specific questionnaire (SSQ) was developed based on patient interviews prior to the trial. Two subgroups were analyzed: patients with benign and patients with malignant tumors (including brain metastases). As a subgroup within malignant lesions, patients with glioblastoma (GBM) were also analyzed separately.

Results
Of patients, 87.5% with GBM presented with results > 16 points on the Center for Epidemiologic Studies Depression Scale (CES-D) after surgery. A decline in patients with benign brain tumors (p = 0.0058) and an increase in patients with malignant tumors (p = 0.0491) could be shown over time for CES-D scores. In this study, we established a new prototype screening tool for depression. In patients diagnosed with GBM, the number of patients needed to screen for identification of symptoms of depression was 1.59. Best time for screening was 35 days after surgery.

Conclusions
Considering the high prevalence and low number needed to screen of depression in patients diagnosed with GBM, we strongly encourage their routine screening during follow-up appointments (35 days after surgery). We encourage a plan to further establish the questionnaire developed in this pilot study.
Die psychoanalytische Ausbildungssupervision – zwischen institutioneller Undurchsichtigkeit, analytischer Neugier und generativem Impuls
Authors: Grünewald-Zemsch G. 
Published: May 2023

ZusammenfassungDie psychoanalytische Ausbildungssupervisionsbeziehung beinhaltet neben der rationalen Erwachsenenbildungssituation eine deutlich emotionale Komponente: psychoanalytische Erfahrungsqualitäten wie projektive Aspekte, das Auftauchen, Erkennen und Bearbeiten von unbewusstem Material aufseiten von Supervisand*in und Supervisor*in, die Bewältigung von Nichtverstehen usw. Zunächst anhand einer verdichteten Fallvignette und an der Beschreibung der Konfliktpotentiale in der Ausbildungssupervision soll gezeigt werden, dass dieser eine zentrale Bedeutung in der Ausbildung zukommt und ihre Weiterentwicklung viel zur Generativität der institutionellen psychoanalytischen Ausbildung beitragen kann.
Modeling the social determinants of resilience in health professions students: impact on psychological adjustment

Published: May 2023

AbstractStressors inherent to training and stemming from the learning environment are associated with high rates of burnout, depression, and mental health problems in health professions students (HPS). There is evidence that disadvantaged or stigmatized groups are particularly affected. These problems not only impact students after graduation but may also have detrimental effects on patient outcomes. Resilience, conceptualized as the process of adapting well in the face of adversity, has inspired an increasing number of interventions aimed at addressing those problems in HPS. These interventions have mostly targeted individual students and their psychological traits while ignoring social and structural factors that may enhance or undermine individual resilience. To address this gap in the literature, the authors reviewed the evidence for psychosocial determinants of resilience and proposed a model inspired by the social determinants of health literature and the “upstream–downstream” metaphor. In this theoretical paper, the authors propose that upstream determinants such adverse childhood experiences and socioeconomic and sociodemographic markers of disadvantage have a direct effect on psychological adjustment and an indirect effect mediated by resilience. Additionally, the authors propose that the institutional downstream drivers of learning environment, social support, and sense of belonging moderate the direct and indirect effects of the upstream determinants on psychological adjustment. Future research should test these hypotheses and gather evidence that may guide the development of interventions. The authors present their model as part of a comprehensive response to recent calls to action to address diversity, equity and inclusion in health professions education.
Feed the futureland: an actor-based approach to studying food security projects
Authors: Seay-Fleming Carrie 
Published: May 2023

AbstractCritical development and food studies scholars argue that the current food security paradigm is emblematic of a ‘New Green Revolution’, characterized by agricultural intensification, increasing reliance on biotechnology, deepening global markets, and depeasantization. High-profile examples of this model are not hard to find. Less examined, however, are food-security programs that appear to work at cross-purposes with this model. Drawing on the case of Feed the Future in Guatemala, I show how USAID engages in activities that valorize ancestral crops, subsistence production, and agroecological practices. Rather than the result of macro-level planning—of either the New Green Revolution or a greener reform regime—I argue that nonconforming food security projects can be traced to individual actors and their interactions on the ground. I draw on an ‘interface approach’ (Long 1990), focusing on the lifeworlds of development workers, their interfaces with each other, and with the to-be-developed. Doing so reveals how food security projects are significantly shaped by the relationships and interests of development actors enmeshed in particular organizational and national settings. This research contributes a fresh perspective on the food security paradigm and its role within the ‘corporate food regime’.
Economic Booms and Recidivism
Authors: Eren Ozkan , Owens Emily 
Published: May 2023

Abstract
Objectives
This paper examines the impact of local economic activity on criminal behavior. We build on existing research by relaxing the identification assumptions required for causal inference, and estimate the impact of local economic activity on recidivism.

Methods
We use the fracking boom as a source of credibly exogenous variation in the economic conditions into which incarcerated people are released. We replicate and extend existing instrumental variables analyses of fracking on how many released offenders return to state prison seperately from aggregate crime and arrests.

Results
Our instrumental variables estimates imply that a ten thousand dollar increase in the value of per capita production is associated with a 2.8% reduction in the 1-year recidivism of ex-offenders at the county level. Improved labor market conditions, specifically an increase in wages for young adults, may explain a non-negligible fraction of the reduction in recidivism associated with economic booms. In contrast, we replicate existing work finding that fracking increased aggregate measures of crime and arrests.

Conclusion
Increased economic opportunity appears to have a different impact of overall crime than on recidivism. This suggests that the relationship between economic opportunity and offending may be conditioned by local social ties. Further research examining how social connections and labor markets affect individual criminal behavior is needed.
Is higher education more important for firms than research? Disentangling university spillovers
Authors: Bonaccorsi Andrea , Barin Laura , Belingheri Paola , Biagi Federico , Sanchez-Barrioluengo Mabel 
Published: May 2023

AbstractThe paper is the first attempt to integrate microdata on universities and firms across most European countries in order to disentangle the impact of knowledge spillovers from human capital (graduates) and intellectual capital (codified research output) on the performance of firms. Data cover all Higher Education Institutions (HEIs) registered in the official European Tertiary Education Register (ETER). Data on performance of firms are from ORBIS and refer to change in the 2011–2015 period in turnover, total assets, intangible assets, and employment. Firms are georeferred and the spillovers from all HEIs located at a given distance are summed and integrated. The findings suggest that, among knowledge spillovers, the creation of human capital via education of students has a larger impact than the circulation of research knowledge. Moreover, the two factors seem to be complements rather than substitutes. Spatial proximity is important for embodied knowledge spillovers (i.e. educated people), while for codified and disembodied spillovers (citations to publications) the spatial dimension is less relevant. The findings have important managerial and policy-making consequences.

AbstractIn 2019, Native youth had the highest rate of teen pregnancy of all racial/ethnic groups. “Respecting the Circle of Life” (RCL) is one of the first evidence-based teen pregnancy prevention programs for Native teens and there is interest in replicating the program across tribal communities. To inform replication, it is important to consider process data including quality, fidelity, and dosage as these may all moderate impact of the program. Participants were Native youth aged 11–19 and a trusted adult. This study includes participants randomized to the RCL program only (N = 266). Data sources include independent observations, facilitator self-assessments, attendance logs, and self-report assessments completed by enrolled youth at baseline and 3 months post assessment. Data was compiled and summed by cohort. Dosage was number of minutes participating in activities separated by theoretical constructs. Linear regression models were utilized to assess moderation of the effects of the intervention dosage on outcomes of interest. Eighteen facilitators delivered RCL. One hundred eighteen independent observations and 320 facilitator self-assessments were collected and entered. Findings indicate RCL was implemented with high fidelity and quality (4.40 to 4.82 out of a 5-point Likert scale; 96.6% of planned activities completed). Dosage was high with an average completion of 7 out of 9 lessons. There was no association between theoretical construct dosage and outcomes of interest. Overall, this study indicates RCL was delivered with high fidelity, quality, and dosage in this trial. This paper informs future replication of RCL and provides support for hiring paraprofessionals from the local community as facilitators, delivering the RCL to peer groups of the same age and sex, delivering the RCL with short duration and high frequency, and encouraging youth to attend all RCL lessons, but continue to serve youth who have missed one or more lessons.
