Published: April 2023

AbstractEvaluation of the hydrological impact of urbanization-induced land use land cover (LULC) changes for medium to large catchments is still an important research topic due to the lack of evidence to conclude about how local changes translate to impacts across scales. This study aims to provide evidence on the effects of LULC change on the streamflow of the Akaki catchment that hosts Addis Ababa, the capital city of Ethiopia. Since the comparative performance of classification algorithms is poorly understood, we compared the performance of one parametric and five non-parametric machine learning methods for LULC mapping using Landsat imageries. To investigate the effect of LULC changes on streamflow, a semi-distributed HEC-HMS model was calibrated and validated using daily discharge data at multiple sites. Findings of this study showed that: (i) the accuracy of classification and regression tree (CART) was superior to the other classifiers, (ii) from 1990 to 2020, urban and forest cover increased at the expense of agricultural and bare land, (iii) the performance of the HEC-HMS model was acceptable at all stations during both the calibration and validation periods, and (iv) the mean annual and main rainy seasonal streamflow of the catchment experienced significant increases due to LULC change but the simulated streamflow changes highly varied with the type of LULC classifier. This study contributes to the limited evidence on how catchments, with rapidly developing cities are prone to hydrological regime changes that need to be recognized, understood and quantified, and incorporated into urban planning and development.
Kompetenzerhalt für Nicht-Routine-Situationen an hochautomatisierten Arbeitsplätzen der chemischen und pharmazeutischen Produktion
Authors: Conein Stephanie , Felkl Thomas 
Published: April 2023

ZusammenfassungMit fortschreitender Digitalisierung wurden zahlreiche Studien zur Identifizierung neuer Kompetenzanforderungen durchgeführt. Nur wenige jedoch beschäftigten sich mit bestehenden Kompetenzanforderungen, die vor allem in Nicht-Routine-Situationen (NRS) weiterhin aktuell sind. In NRS müssen Fachkräfte eine Fülle von Kenntnissen und Fähigkeiten ad hoc mobilisieren, um schnell und kompetent Entscheidungen zu treffen. Diese Kenntnisse und Fähigkeiten werden jedoch aufgrund der Automatisierung im Routinefall nur noch selten benötigt und sind daher in Gefahr, vergessen zu werden. Die Problematik wurde bereits in Hochrisikobranchen mit hohem Automatisierungsgrad erforscht, für die chemische oder pharmazeutische Produktion gibt es jedoch bisher keine empirischen Untersuchungen. Das vorliegende Forschungsprojekt möchte diese Lücke schließen.Praktische Relevanz: Wenn in Nicht-Routine-Situationen (NRS) der chemischen und pharmazeutischen Produktion nicht kompetent gehandelt wird, so kann dies zu (teilweise hohen) Kosten oder auch zur Gefährdung von Personen führen. Durch das vermehrte Arbeiten in automatisierten Arbeitsumgebungen steigt die Gefahr des Verlustes eben jener Kompetenzen, die in den NRS relevant sind. Diese Problematik genau zu erfassen (welche Kompetenzen sind betroffen etc.) und die möglichen Einflussfaktoren (Art der Arbeitsaufgabe, individuelle Dispositionen der Fachkräfte etc.) zu erkennen, ist Grundlage dafür, mögliche Maßnahmen zur Verhinderung des Kompetenzverlustes zu planen und zu implementieren.
The Impact of Job Similarity Along the Career Path on the Firm’s Promotion Strategy
Authors: Infuehr Jakob , Kronenberger Sebastian 
Published: April 2023

AbstractFirms use job promotions to incentivize hard work from low-level employees and to sort employees according to their skills. Since these two functions are often in conflict, a firm’s promotion strategy tries to balance them. Our model extends prior research by identifying job similarity between current and future job as a driver of a firm’s promotion strategy. When compensation costs are high or external hiring options poor, then higher job similarity leads to fewer internal promotions. Otherwise, higher job similarity can lead to more internal promotions. These results help to explain why firms with different structures or from different industries apply different promotion strategies.
Inflation and Valuation Practice: German Evidence
Authors: Schüler Andreas , Wünsche Sebastian 
Published: April 2023

AbstractThe objective of our paper is to analyze, how valuation practice deals with inflation especially for the terminal value, and how company value is influenced by assumptions set by practitioners. For that reason, we examine how vulnerable companies could be regarding struggles to pass on inflationary effects to their customers. We analyze the inflation rates assumed for the steady-state (terminal value) by comparing them to different estimators for the inflation rate expected at the valuation date (Survey of Professional Forecasters, inflation rates derived by comparing real and nominal rate of returns, inflation swaps). We quantify the implications of using different inflation rates for future cash flow development, terminal value and the company value at the valuation date, and compare nominal reported values with company values in a (hypothetical) world without inflation. Our sample consists of 263 valuation reports written by German auditors with valuation dates between 2000 to 2021. Most of the reports aim at determining the price per share to compensate minority shareholders during a squeeze-out. Our results question inter alia the preference for a constant company specific inflation rate of around 1% on average, and we quantify a number of value effects.
Vulnerable Women: Negotiations Among Migrant Women in the Aftermath of the Ukraine War
Authors: Boman Björn 
Published: April 2023

AbstractWomen, in the past and to different extents in the present, have typically constituted a vulnerable although heterogenous social group. After the foundation of a “new” sovereign post-Soviet Union Ukraine in 1991, large numbers of women in poverty were exposed to human trafficking, prostitution, and labor. Since Russia’s war in Ukraine in 2014, many internally displaced persons and migrants have left their places of sojourn for other cities in Ukraine or to go overseas. This situation is exacerbated after Russia’s full-scale invasion in 2022. The current situation constitutes a double-edged sword: on the one hand opportunities to seek more profitable work environments in wealthier cities and countries, but on the other hand a risk of being exploited. Others want to leave but cannot not due to constraining factors such as financial difficulties. With the aid of proculturation theory,N = 5 Ukrainian women were interviewed. Their discourses highlight a negotiation between the Ukrainian and the European in regard to familiar/unfamiliar spheres.
Exploring the Burden of Cancer in Pakistan: An Analysis of 2019 Data
Authors: Tufail Muhammad , Wu Changxin 
Published: April 2023

AbstractCancer has become a growing burden in Pakistan in recent times, posing a significant cause for concern. The World Health Organization has reported a steady increase in the incidence of cancer in Pakistan. According to the present study, breast cancer (24.1%), oral cavity (9.6%), colorectum (4.9%), esophagus (4.2%), and liver cancer (3.9%) were the five most prevalent cancers. Males were more likely to have oral cavity cancer (14.9%), colorectum cancer (6.8%), liver cancer (6.4%), prostate cancer (6.0%), and lung cancer (6.0%). In women (41.6%), breast (6.9%), oral cavity (5.5%), cervix (4.7%), and uterus cancer (4.1%) were the most common cancers. Middle-aged people (43.0%) were most likely to develop cancer, followed by seniors (30.0%) and adults (20.0%). Children and adolescents were most likely to develop cancers of the central nervous system (CNS), leukemia (18.7%), and Hodgkin (17.3%), followed by breast, oral cavity, colorectum, and prostate at other ages. Most patients were from Punjab (40.4%) and Sindh (32.2%). Approximately 30.0% of patients were diagnosed at stage III and stage IV. In terms of registered cases, breast cancer, oral cavity cancer, colon cancer, esophagus cancer, and liver cancer are among the highest. In the future, this information may prove useful for assessing the effectiveness of interventions.

Published: April 2023

Abstract
Over the past 20 years, tremendous advances in sequencing technologies and computational algorithms have spurred plant genomic research into a thriving era with hundreds of genomes decoded already, ranging from those of nonvascular plants to those of flowering plants. However, complex plant genome assembly is still challenging and remains difficult to fully resolve with conventional sequencing and assembly methods due to high heterozygosity, highly repetitive sequences, or high ploidy characteristics of complex genomes. Herein, we summarize the challenges of and advances in complex plant genome assembly, including feasible experimental strategies, upgrades to sequencing technology, existing assembly methods, and different phasing algorithms. Moreover, we list actual cases of complex genome projects for readers to refer to and draw upon to solve future problems related to complex genomes. Finally, we expect that the accurate, gapless, telomere-to-telomere, and fully phased assembly of complex plant genomes could soon become routine.
Collecting “Remembrances of these Isles”: Tracing the Post-1880 History of a Taíno Cotton Cemí in the Dominican Republic and Italy
Authors: Ostapkowicz Joanna , Pennacini Cecilia 
Published: April 2023

AbstractThis article charts the collection history of the only surviving precolumbian cotton reliquary (cemí) from the Dominican Republic, establishing its provenance from the mid-nineteenth century through a previously unpublished manuscript written by the collector, Rodolfo Domingo Cambiaso Sosa, and using archival documents in Italy. The cemí, found in a cave in the southwest of the country near the town of Petitrou (Enriquillo), was purchased in 1882 by Admiral Giuseppe Giovanni Battista Cambiaso, one of the founders of the Dominican Navy. It emerged in international publications commemorating the quadricentennial of the Spanish–Indigenous encounter in 1892 and shortly thereafter was sent to Genoa, Italy. It entered the collections of Turin's Royal Museum of Antiquities in 1928 before being passed to the newly established Museum of Anthropology and Ethnography. It was rediscovered by Dominican scholars in the 1970s and has inspired numerous investigations since, including renewed collaborative links between the Dominican Republic and Italy.

Comparing LiDAR and IMU-based SLAM approaches for 3D robotic mapping
Authors: Tiozzo Fasiolo Diego , Scalera Lorenzo , Maset Eleonora 
Published: April 2023

AbstractIn this paper, we propose a comparison of open-source LiDAR and Inertial Measurement Unit (IMU)-based Simultaneous Localization and Mapping (SLAM) approaches for 3D robotic mapping. The analyzed algorithms are often exploited in mobile robotics for autonomous navigation but have not been evaluated in terms of 3D reconstruction yet. Experimental tests are carried out using two different autonomous mobile platforms in three test cases, comprising both indoor and outdoor scenarios. The 3D models obtained with the different SLAM algorithms are then compared in terms of density, accuracy, and noise of the point clouds to analyze the performance of the evaluated approaches. The experimental results indicate the SLAM methods that are more suitable for 3D mapping in terms of the quality of the reconstruction and highlight the feasibility of mobile robotics in the field of autonomous mapping.
The Myth of “Just” Nuclear Deterrence: Time for a New Strategy to Protect Humanity from Existential Nuclear Risk
Authors: Rohlfing Joan 
Published: April 2023

AbstractNuclear weapons are different from every other type of weapons technology. Their awesome destructive potential and the unparalleled consequences of their use oblige us to think critically about the ethics of nuclear possession, planning, and use. Joe Nye has given the ethics of nuclear weapons deep consideration. He posits that we have a basic moral obligation to future generations to preserve roughly equal access to important values, including equal chances of survival, and proposes criteria for achieving conditional or “just deterrence” to minimize the risk of nuclear use and help preserve these values. While Nye's conditions are laudable, they are not achievable. They rely on flawed assumptions about the nature of nuclear weapons and the inherent risks of the nuclear deterrence system. Since the Cold War ended, the strategy and practice of nuclear deterrence has grown riskier, more urgent, more dangerous, and less stable. It is time to rethink how we manage nuclear risks. A new nuclear security system must be built on the design principle that the consequences of system failure cannot threaten to end or fundamentally disrupt civilization. We owe the future a new nuclear security strategy that can prevent an existential global nuclear event.
Ramsey upper density of infinite graphs
Authors: Lamaison Ander 
Published: April 2023

AbstractFor a fixed infinite graph$H$, we study the largest density of a monochromatic subgraph isomorphic to$H$that can be found in every two-colouring of the edges of$K_{\mathbb{N}}$. This is called the Ramsey upper density of$H$and was introduced by Erdős and Galvin in a restricted setting, and by DeBiasio and McKenney in general. Recently [4], the Ramsey upper density of the infinite path was determined. Here, we find the value of this density for all locally finite graphs$H$up to a factor of 2, answering a question of DeBiasio and McKenney. We also find the exact density for a wide class of bipartite graphs, including all locally finite forests. Our approach relates this problem to the solution of an optimisation problem for continuous functions. We show that, under certain conditions, the density depends only on the chromatic number of$H$, the number of components of$H$and the expansion ratio$|N(I)|/|I|$of the independent sets of$H$.

Published: April 2023

AbstractA 14-year-old previously healthy female presented with chest pain and dyspnoea for 2 days in the setting of a recent upper respiratory infection. She had elevated inflammatory markers and troponin, resulting in the diagnosis of acute myocarditis. Transthoracic echocardiography demonstrated mild systolic dysfunction and a moderate pericardial effusion. Additionally, her echocardiogram showed concentric left ventricular hypertrophy raising concern for hypertrophic cardiomyopathy. She was treated with intravenous immunoglobulin. Serial echocardiograms revealed rapid resolution of her ventricular hypertrophy. Cardiac magnetic resonance confirmed the diagnosis of myocarditis.

Published: April 2023

AbstractGenetic diversity is essential for the development of more efficient plant types. In the present study, 529 chickpea accessions were evaluated for their agronomic performance, genetic divergence and identification of promising accessions through the use of a simple lattice design. These accessions varied widely in all agronomic traits. The first three principal components (PCs) explained 78.35% variation. The PC1 and PC2 explained 38.05 and 24.30% of total variations. Three traits namely, branches per plant, pods per plant and seed yield per plant contributed to maximum variation. The hierarchical clustering analysis carried out on PCs grouped the accessions into eight clusters. Among 127 selection indices formulated, higher relative efficiency (422.52%) coupled with high genetic advance (34.31%) was exhibited by the combination involving six characters. Based on the index score of greater than 100, 15 genotypes were promising for improving the grain yield. The results of both PC analysis (PCA) and selection indices suggested that branches per plant, pods per plant and 100-seed test weight traits have to be considered for any genetic yield gains. Both the techniques (PCA and selection indices) identified three genotypes (GAG 0733, IC 268988 and IC 269031) as the best performers, suggesting that the two techniques are equally efficient in the identification of superior germplasm that can be used in chickpea hybridization programmes for yield improvement.

AbstractUnderstanding how droughts are characterized, propagated, and projected, particularly multivariate droughts, is necessary to explain the variability and changes in drought characteristics. This study aims to understand multimodel global drought monitoring, propagation, and projection by utilizing a multivariate standardized drought index (MSDI) during the historical (1959–2014) and future (2045–2100) periods under two socioeconomic pathways SSPs (370 and 585), derived from the bias‐corrected Coupled Model Intercomparison Project Phase 6 (CMIP6). Based on the energy metrics, the multivariate bias correction method outperformed other techniques in correcting the biases in the CMIP6 drought representation. The drought indicators demonstrate distinct categories for meteorological, hydrological, and multivariate droughts. There were significant high cross correlations between Heatwave Total Length (HWTL) and MSDI in Africa and South America for all lagged times. Europe and North America generally saw the maximum MSDI drought duration (228 months) during the historical period. For future projections, Africa recorded the maximum drought duration (197 months), while Europe witnessed the minimum drought duration for SSP 370 (171 months), and North America (149 months) for SSP 585. Furthermore, during the historical period in tropical Africa, the propagation of meteorological to hydrological drought was slower during the wet months than during the dry months. Under the SSP 370 future projection, there was a shift in the long period of meteorological‐hydrological propagation from the middle and late wet months to the beginning of the wet months in tropical Africa. Therefore, tracking and projecting drought characteristics is vital for understanding the risk of drought‐related consequences.
Tracking the Provenance of Aeolian Loess in Northeastern China by Uranium Isotopes

Published: April 2023

AbstractThe aeolian loess deposits in northeastern China have substantial potential for reconstructing the paleoclimate in the East Asian monsoon boundary zone. Identifying the source of the aeolian dust is crucial to interpret the paleo‐proxies recorded in the loess deposits in northeastern China; however, traditional geochemical tracers such as Nd and Sr isotopes cannot discriminate between the potential source areas, that is, the Otindag Sandy Land, Horqin Sandy Land, and Hulun Buir Sandy Land regions. In this study, the (234U/238U) activity ratio is used to constrain the provenance of the loess deposits in northeastern China. The (234U/238U) of the studied loess‐paleosol sequences (from 0.935 to 0.910) decreases with increasing depositional age (from 10 to ∼1,000 ka), which is consistent with predictions from uranium isotope comminution age model. A derived (234U/238U) of 0.935 ± 0.003 for the newly deposited loess (zero depositional age) is most similar to that of the Otindag Sandy Land positioned at a proximal upwind direction, suggesting that the Otindag Sandy Land is the most likely source of the aeolian dust that formed the loess deposits in northeastern China. A transportation time of 432 ± 65 ka was calculated for these deposits, indicating extensive mixing of the fine dust in the source regions, which could partially explain the relative homogeneity of loess deposits in northeastern China. The transportation time longer than several glacial‐interglacial cycles suggests that reconstructions of regional paleoclimate on orbital timescales should be viewed with caution because the potential influence of climatic changes could largely be buffered.
Spatial Changes in Gas Transport and Sediment Stiffness Influenced by Regional Stress: Observations From Piezometer Data Along Vestnesa Ridge, Eastern Fram Strait

AbstractGas transport through sediments to the seabed and seepage occurs via advection through pores, faults, and fractures, and as solubility driven gas diffusion. The pore pressure gradient is a key factor in these processes. Yet, in situ measurements for quantitative studies of fluid dynamics and sediment deformation in deep ocean environments remain scarce. In this study, we integrate piezometer data, geotechnical tests, and sediment core analyses to study the pressure regime that controls gas transport along the Vestnesa Ridge in the eastern Fram Strait. The data show a progressive westward decrease in induced pore pressure (i.e., from c. 180 to c. 50 kPa) upon piezometer penetration and undrained shear strength of the sediments, interpreted as a decrease in sediment stiffness. In addition, the data suggest that the upper c. 6 m of sediments may be mechanically damaged due to variations in gas diffusion rates and exsolution. Background pore pressures are mostly at hydrostatic conditions, but localized excess pore pressures (i.e., up to 10 kPa) exist and point toward external controls. When analyzed in conjunction with observations from geophysical data and sediment core analyses, the pore pressure data suggest a spatial change from an advection dominated to a diffusion dominated fluid flow system, influenced by the behavior of sedimentary faults. Understanding gas transport mechanisms and their effect on fine‐grained sediments of deep ocean settings is critical for constraining gas hydrate inventories, seepage phenomena and sub‐seabed sediment deformations and instabilities.
