Gestörte Lieferketten — wie reagieren die Betriebe in Deutschland?
Authors: Kagerl Christian , Moritz Michael , Roth Duncan , Stegmaier Jens , Stepanok Ignat 
Published: February 2023

ZusammenfassungDer Ausbruch der Coronapandemie 2020 hat die Abhängigkeit der deutschen Wirtschaft von globalen Lieferketten offengelegt. Verzögerungen bei der Zulieferung oder der Ausfall von Vorprodukten infolge eingeschränkter Logistikkapazitäten, geschlossener Grenzen oder einer gestörten Produktion bei Zulieferern hat seitdem bei vielen Betrieben in Deutschland zu Problemen geführt. Mit dem Angriff Russlands auf die Ukraine im Februar 2022 wurde deutlich, dass Lieferketten auch erheblichen geopolitischen Risiken ausgesetzt sind. Die Unternehmen stehen vor der Aufgabe, ihre Zulieferketten resilienter gegen solche Risiken zu machen.
An algorithm to compute the average-of-awards rule for claims problems with an application to the allocation of CO$$_2$$ emissions

Published: February 2023

AbstractThe set of awards vectors for a claims problem coincides with the core of the associated coalitional game. We analyze the structure of this set by defining for each group of claimants a, so called, utopia game, whose core comprises the most advantageous imputations available for the group. We show that, given a claims problem, the imputation set of the associated coalitional game can be partitioned by the cores of the utopia games. A rule selects for each claims problem a unique allocation from the set of awards vectors. The average-of-awards rule associates to each claims problem the geometric center of the corresponding set of awards vectors. Based on the decomposition of the imputation set, we obtain an interpretation of the average-of-awards rule as a point of fairness between stable and utopia imputations and provide a backward recurrence algorithm to compute it. To illustrate our analysis, we present an application to the distribution of CO$$_2$$

Data-driven dependency parsing of Vedic Sanskrit
Authors: Hellwig Oliver , Nehrdich Sebastian , Sellmer Sven 
Published: February 2023

AbstractThis paper describes the first data-driven parser for Vedic Sanskrit, an ancient Indo-Aryan language in which a corpus of important religious and philosophical texts has been composed. We report and critically discuss experiments with the input feature representations, paying special attention to the performance of contextualized word embeddings and to the influence of morpho-syntactic representations on the parsing quality. In addition, we provide an in-depth discussion of the parsing errors that covers structural traits of the predicted trees as well as linguistic and extra-textual influence factors. In its optimal configuration, the proposed model achieves 87.61 unlabeled and 81.84 labeled attachment score on a held-out set of test sentences, demonstrating good performance for an under-resourced language.
Physiological and morphological responses of ‘Irukandji’ polyps to thermal and osmotic conditions: consequences for niche profiling

Published: February 2023

AbstractThe Irukandji jellyfish (Carukia barnesi) is a medically important species. While the medusa stage of this species is well known, due to its highly venomous sting, the benthic polyp has core roles in regulating both the timing and abundance of medusa making it a research priority. However, due to their small size, Carukia barnesi polyps have never been found in situ and, basic ecological knowledge surrounding this life stage is limited. In this study we adopt a lab-based approach, utilizing physiological tolerance as a functional tool, to gain new insights into the in situ location for Carukia barnesi polyps. The physiological tolerance of Carukia barnesi polyps was characterized by measuring the oxygen consumption rates of polyps exposed to different salinity/temperature combinations. A total of nine salinities and seven temperatures were investigated, ranging from 11 °C/16‰ to 34 °C/42.5‰, encompassing the spectrum of environments experienced on the Great Barrier Reef. Polyps were also monitored for morphological changes such as asexual reproduction, polyp deterioration, and mortality. Salinity did not have a significant effect on oxygen consumption rates, with Carukia barnesi polyps displaying a significant tolerance to a wide range of salinities. The effect of temperature, however, was statistically significant with oxygen °consumption rates increasing alongside water temperature. There was no statistical evidence to support an interactive effect between salinity and temperature. Based on these results, we conclude that the polyp stage of this species is likely located in an environment with stable temperatures and fluctuating salinities and, consequently, future endeavors aimed at locating this life stage should expand targeted survey areas outside stable oceanic environments, typical of medusa, and encompass dynamic environments such as estuaries and submarine freshwater upwellings.

Published: February 2023

Abstract
Purpose
The incidence of birth defects is increased in children born after assisted reproductive technologies (ART). However, changes in ART over time could influence this incidence. To investigate this issue, we present the frequency and trends of birth defects in ART and natural pregnancies in Lombardy, Northern Italy, during the period 2014–2020.

Methods
This is a population-based study using automated system of healthcare utilization (HCU) databases. ART pregnancies included only those obtained with conventional IVF or ICSI. After identifying the total number of deliveries, the rate of newborns with birth defects was compared between natural and ART pregnancies. A logistic regression model was used to calculate the adjusted odd ratio (OR). Analyses were repeated for every calendar year.

Results
Overall, 508,421 deliveries were identified, of which 14,067 (2.8%) were achieved after IVF-ICSI. A decreasing trend in birth defects over time was highlighted. The adjusted OR dropped from 1.40 (95%CI: 1.03–1.91) in 2014 to 0.92 (95%CI: 0.69–1.22) in 2020. During the study period, a significant reduction in multiple pregnancy and in the ratio of ICSI to conventional IVF was also observed, explaining at least in part the positive trend observed for birth defects.

Conclusion
The increased risk of birth defects in children born after IVF-ICSI is not steady over time. A decline of this risk emerged in our region. Policy changes in ART may explain this beneficial effect.
The Alarm Pheromone and Alarm Response of the Clonal Raider Ant
Authors: Lopes Lindsey E. , Frank Erik T. , Kárpáti Zsolt , Schmitt Thomas , Kronauer Daniel J. C. 
Published: February 2023

Abstract
Ants communicate via an arsenal of different pheromones produced in a variety of exocrine glands. For example, ants release alarm pheromones in response to danger to alert their nestmates and to trigger behavioral alarm responses. Here we characterize the alarm pheromone and the alarm response of the clonal raider ant Ooceraea biroi, a species that is amenable to laboratory studies but for which no pheromones have been identified. During an alarm response, ants quickly become unsettled, leave their nest pile, and are sometimes initially attracted to the source of alarm, but ultimately move away from it. We find that the alarm pheromone is released from the head of the ant and identify the putative alarm pheromone as a blend of two compounds found in the head, 4-methyl-3-heptanone and 4-methyl-3-heptanol. These compounds are sufficient to induce alarm behavior alone and in combination. They elicit similar, though slightly different behavioral features of the alarm response, with 4-methyl-3-heptanone being immediately repulsive and 4-methyl-3-heptanol being initially attractive before causing ants to move away. The behavioral response to these compounds in combination is dose-dependent, with ants becoming unsettled and attracted to the source of alarm pheromone at low concentrations and repulsed at high concentrations. While 4-methyl-3-heptanone and 4-methyl-3-heptanol are known alarm pheromones in other more distantly related ant species, this is the first report of the chemical identity of a pheromone in O. biroi, and the first alarm pheromone identified in the genus Ooceraea. Identification of a pheromone that triggers a robust, consistent, and conserved behavior, like the alarm pheromone, provides an avenue to dissect the behavioral and neuronal mechanisms underpinning chemical communication.

Published: February 2023

AbstractHedging at-the-money digital options near maturity, remains a challenge in quantitative finance. In the present work, we carry out a hedging strategy by means of a bull spread. We study the probability of super- and sub-hedge the digital option and minimize the probability of a sub-hedge considering the cost of hedging and illiquidity issues. We perform a wide variety of numerical experiments under different models for the underlying asset dynamics. A calibration to market data is provided and used to get the optimal composition of the bull spread satisfying the cost of hedging restriction.
A multi-sensing scheme based on nonlinear coupled micromachined resonators

Published: February 2023

AbstractA new multi-sensing scheme via nonlinear weakly coupled resonators is introduced in this paper, which can simultaneously detect two different physical stimuli by monitoring the dynamic response around the first two lowest modes. The system consists of a mechanically coupled bridge resonator and cantilever resonator. The eigenvalue problem is solved to identify the right geometry for the resonators to optimize their resonance frequencies based on mode localization in order to provide outstanding sensitivity. A nonlinear equivalent model is developed using the Euler–Bernoulli beam theory while accounting for the geometric and electrostatic nonlinearities. The sensor's dynamics are explored using a reduced-order model based on two-mode Galerkin discretization, which reveals the richness of the response. To demonstrate the proposed sensing scheme, the dynamic response of the weakly coupled resonator is investigated by tuning the stiffness and mass of the bridge and cantilever resonators, respectively. With its simple and scalable design, the proposed system shows great potential for intelligent multi-sensing detection in many applications.
Hiring family or non-family managers when non-economic (sustainability) goals matter? A multitask agency model
Authors: Kragl Jenny , Palermo Alberto , Xi Guoqian , Block Joern 
Published: February 2023

AbstractNepotism, altruism, lower managerial abilities, and a small pool of qualified family candidates may speak against family management. However, a large share of family-owned firms is run by family managers. Our study develops a theoretical model that provides an explanation for this paradox, linked to the multitasking problem of managing economic and non-economic tasks in family firms. Comparing the performance of family and non-family managers under moral hazard and imperfect performance measurement, we find that incentive pay leads to an effort distortion towards economic outcomes for both manager types, however less so for family managers. This effort distortion is less pronounced when economic and non-economic management tasks are complements. We show that family managers with excellent skills regarding non-economic goals of the owner family often outperform non-family managers even if they have poor skills in economic tasks or, what is more, if they have lower average abilities altogether. We further show that the interdependence between economic and non-economic goals in the manager’s job tends to have a moderating effect on the family manager’s relative performance. Our study contributes to the literature about family management and agency costs in family firms and has practical implications for family firms’ hiring decisions. By highlighting the importance of non-economic goals, it moreover adds to the current discussion about the compliance with firms’ sustainability goals.
Farmers’ perceptions and acceptance of crossbred guinea pigs in Mantaro Valley, Peru

AbstractThis study aimed at assessing farmers’ perceptions and acceptance of the proposed breeding strategy of Instituto Veterinario de Investigaciones Tropicales y de Altura (IVITA), located in the Central Andes of Peru. A total of 34 farmers, who had received guinea pigs from IVITA, were interviewed. The questionnaire was performed in Spanish language and covered topics about the guinea pig production, feeding, mating system, training, the main products, perception and acceptance of crossbred lines (“cuy RG”), and the farmers’ comment about the terminal crossbred animal (“cuy G”). The preferred feeding strategy was a combination of forage and supplement. All farmers implemented a controlled mating system. Most farmers had received training on feeding, reproduction, management, equipment, and facilities. The main product is animals for slaughter. The 82.40% of farmers reported that they do not purchase guinea pigs from IVITA anymore, because they are highly susceptibility to lymphadenitis, which is a highly contagious disease and causes swollen lymph nodes and affects the meat quality. Most of the respondents classified the “cuy RG” and “cuy G” as suitable for meat production and were satisfied with the performance of the animals. Therefore, 58.80% of respondents already recommended “cuy RG” to other farmers. However, 17.70% of the respondents would not recommend these animals because they are susceptible to disease, especially lymphadenitis. Therefore, IVITA should engage in more structured dialogue with farmers and regularly include their opinion in future improvement of its breeding strategies. This could help to reach higher acceptance rates by farmers.

AbstractCannabis is the fourth psychoactive substance to be legalized which are of far-reaching significance to the world. We analyzed data from the 2019 Global Burden of Disease Study (GBD) to estimate the incidence and prevalence of cannabis use disorder (CUD) and calculated the disease burden of CUD in 204 countries and territories and 21 regions over the past three decades. We reported disease burden due to CUD in terms of disability-adjusted life years (DALYs), age-standardized rate (ASR), estimated annual percentage change (EAPC), and analyzed associations between the burden of CUD and sociodemographic index (SDI) quintiles. Globally, the number of incidence cases of CUD was estimated to be increasing by 32.3% from 1990 to 2019 and males are nearly double higher than that of female. DALYs increase 38.6% from 1990. Young people aged 20–24 years old with cannabis use disorder have the highest DALYs in 2019, followed by those younger than 20 years old. India, Canada, USA, Qatar, Kenya, and high SDI quintile areas showed a high burden of disease. Nearly 200 million individuals are cannabis users worldwide, and CUD is a notable condition of GBD. The global cultivation of cannabis, rooted in different cultures, diversified access to cannabis, legalization in controversy, the promotion of medical cannabis, and many other factors promote the global cannabis industry is constantly updated and upgraded. It deserves more discussion in the future in terms of pathophysiological mechanisms, socioeconomics, law, and policy improvement.
Arbeitsanforderungen und Ressourcen der digitalen Mediennutzung bei Lehrkräften
Authors: Cramer Malte , Hosenfeld Ingmar 
Published: February 2023

Zusammenfassung
Hintergrund
Die Nutzung digitaler Medien ist für einen Teil der Lehrkräfte mit einem erhöhten Belastungserleben verbunden. Stress, der durch negative Aspekte der digitalen Mediennutzung entsteht, wird unter dem Begriff „digitaler Stress“ oder „Technostress“ v. a. in internationalen Studien untersucht. Für deutsche Lehrkräfte ist die Befundlage hingegen rar. Dem gegenüberstehend scheint ein weiterer Teil der Lehrkräfte geringere Schwierigkeiten mit der fortschreitenden Implementierung digitaler Medien in den Schulalltag zu haben und stattdessen von den Vorteilen digitaler Medien zu profitieren. Empirisch vernachlässigt wurde dabei die Frage, inwiefern sich diese Vorteile als Ressource positiv auf Stress und Wohlbefinden der Lehrkräfte auswirken können.

Ziel
Ziel der Studie ist es, eine Zusammenstellung von potenziellen Einflussfaktoren der digitalen Mediennutzung auf Stress und Wohlbefinden von Lehrkräften aus Deutschland zu erhalten, diese datengeleitet zu strukturieren und hinsichtlich ihrer Wichtigkeit zu bewerten.

Methode
Es wurde die Group-concept-mapping(GCM)-Methode mit 44 angehenden Lehrkräften der Universität Koblenz-Landau durchgeführt.

Schlussfolgerung
Die erzielte Strukturierung zeigt in Verbindung mit der bewerteten Wichtigkeit die Bedeutung positiver Auswirkungen der digitalen Mediennutzung für das Wohlbefinden von Lehrkräften sowie die Relevanz schulischer Rahmenbedingungen auf.
Dynamic Precipitation in Supersaturated Al–Zn–Mg–Cu Alloy During Warm Stretching
Authors: Robson Joseph , Jessner Peter , Taylor Mark , Ma Ziyu 
Published: February 2023

AbstractHigh-strength Al–Zn–Mg–Cu alloys such as AA7075 rely on precipitation to obtain their properties, and the evolution of these precipitates can be strongly influenced by deformation. In this study, the effect of warm stretching on precipitation in supersaturated AA7075 was investigated. A dilatometer was used to enable rapid quenching directly from the solution treatment temperature to the warm stretching temperature. The evolution of precipitates was monitored using small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM). SAXS revealed the presence of clusters only 5 seconds after quenching, and the subsequent evolution of the microstructure involved the growth and coarsening of these clusters. Deformation strongly enhanced the cluster/precipitate growth rate, which increased linearly with increasing strain. A strain rate effect was also noted, with the growth rate being faster at the higher strain rate for the same strain level. However, the acceleration of growth with increasing strain rate was not sufficient to compensate for the reduced time, so that deformation at higher strain rate led to small precipitates (at iso-strain). TEM revealed the precipitates to be homogeneously dispersed in the matrix both with and without deformation. There was no evidence for enhanced nucleation due to deformation, indeed the opposite was the case, with fewer but larger precipitates observed in the deformed microstructure. The linear increase in growth rate with strain is consistent with a dominant effect of excess vacancies in enhancing diffusion rates.

AbstractIn Bangladesh most agronomic biomass (straw, husk, dried dung) is burnt for domestic cooking use. Consequently, the soil is continuously stripped of mineral nutrients and carbon (C) substrate. Here we investigate if recycling of household ash (ash) as fertilizer can sustainably improve soil fertility as well as minimise accumulation of toxic elements (As, Cd) in rice grain. Large scale field trials across two geographic regions (Barind, Madhupur) and two seasons (wet, dry) and with application of 3 fertiliser treatments (NPKS, ash, NPKS + ash) were conducted. At the end of each season, the impact of region*season*treatment on soil microbial comunities, rice yield, and grain quality (As, Cd, nutrient elements) was assessed. When compared to conventional field application rates of NPKS (control), application of ash boosted rice yield by circa. 20% in both regions during wet and dry season, with no effect on rice grain carcinogenic inorganic arsenic (iAs), dimethylarsonic acid (DMA) or cadmium (Cd), but with potential to increase zinc (Zn). For soil microbial communities, a significant region and season effect as well as correlation with elements in rice grain was observed, amongst these Cd, Zn, iAs and DMA. This study illustrates that application of ash can reduce the requirement for expensive chemical fertiliser, whilst at the same time increasing rice yield and maintaining grain quality, making farming in Bangladesh more sustainable and productive. The study also implies that the combined impact of region, season, and soil microbes determines accumulation of elements in rice grain.

Abstract
Background
HPV vaccination has been recommended and reimbursed for girls in Germany since 2007. In June 2018 the German Standing Committee on Vaccination (STIKO) recommended the gender-neutral vaccination of adolescents aged 9 to 14 years with catch-up through age 17. Objectives of this study were to describe the uptake of vaccination in boys before and during the COVID-19 pandemic.

Methods
The study used data from a proprietary electronic medical record database and a database with information on nationally dispensed vaccine doses. The monthly number of first doses of HPV vaccinations in boys and girls aged 9–17 years in the period from 01/2018 to 12/2021 was determined. In addition, for boys the cumulative vaccination rates were calculated for initiated and completed vaccination series.

Results
Four months after the introduction of mandatory reimbursement for boys, the monthly numbers of first doses were comparable to that of girls. Compared to the same month in 2019, the number of first doses declined by up to 49% (girls) in 2020 and 71% (boys) in 2021. At the end of 2021, the vaccination rate for 15-year-old boys (2006 birth cohort) reached 44.4% for initiated and 26.4% for completed series.

Conclusion
After an initial dynamic increase in HPV vaccinations in boys, the impact of COVID-19 was particularly strong in the second year of the pandemic. At the end of 2021 vaccination rates were still low. Efforts are needed to catch-up on adolescents that missed doses during the pandemic and to increase uptake.
