Working-time mismatch and job satisfaction of junior academics
Authors: Frei Irina , Grund Christian 
Published: May 2022

AbstractWe examine the role of working-time mismatches (defined as the difference between actual and desired weekly working hours) in academics’ job satisfaction. In doing so, we investigate how academics’ career stage (predoc vs. postdoc) and contract status (part-time vs. full-time employment) moderate the relation between a mismatch in working hours and job-related well-being. Our results are based on longitudinal survey data among junior academics in the STEM fields indicate that mismatches in working hours are prevalent in academia and are associated with a loss of job satisfaction. In this context, overemployment (working more than desired) tends to unfold more severe consequences with respect to job satisfaction compared to underemployment. We find evidence for a similar reaction of doctoral students and postdocs with respect to job satisfaction when experiencing a working-time mismatch. Part-time employment positively moderates the link between working-time mismatch and job satisfaction for the case of underemployment.
Big bath accounting and CEO turnover: the interplay between optimal contracts and career concerns
Authors: Hensel Tim , Schöndube Jens Robert 
Published: May 2022

AbstractFollowing executive turnovers big bath accounting is often observed. We investigate a new manager’s earnings management incentives in his first year in office in a two-period model with career concerns and earnings’ lack of timeliness. We determine the optimal incentive contract and decompose the manager’s equilibrium earnings management into two components: an explicit incentive resulting from the compensation contract and an implicit incentive from career concerns. While career concerns always motivate the manager to shift earnings backwards, the optimal contract induces the manager to either shift earnings forwards or backwards. In particular, we show that with optimal contracts a "negative" big bath may result in equilibrium, i.e., the manager may inflate earnings after a CEO turnover. We demonstrate how the optimal contract and the equilibrium earnings management strategy depend on the earnings’ timeliness, the precision of the initial information about the manager’s ability and the intensity of competition for CEOs. Our results may help to explain why big bath accounting after a CEO turnover is observed in many but not in all cases.

Abstract
Cadmium (Cd) is a serious pollutant in the environment. Candesartan is an angiotensin II (Ang II) receptor antagonist with promising diverse health benefits. The current study is planned to investigate the hepatorenal protective effects of candesartan against Cd-induced hepatic and renal intoxication. Our results demonstrated that candesartan effectively attenuated Cd-induced hepatorenal intoxication, as evidenced by improving hepatic and renal function biomarkers. Besides, candesartan reversed hepatic and renal histopathological abrasions induced by Cd toxicity. Candesartan antioxidant effect was mediated by Nrf2 activation. Also, candesartan suppressed hepatorenal inflammation by modulating NF-κB/IκB. Moreover, candesartan attenuated Cd hepatorenal apoptosis by upregulating Bcl-2 and downregulating Bax and Cyt-C proteins. Interestingly, these effects are suggested to be an outcome of modulating of Ang II/Ang 1–7 signal. Overall, our findings revealed that candesartan could attenuate Cd-induced hepatorenal intoxication through modulation of Nrf2, NF-κB/IκB, Bax/Bcl-2/Cyt-c, and Ang II/Ang 1–7 signaling pathways.

Abstract
Purpose
Distal metastases are a major cause of poor prognosis in colorectal cancer patients. Approximately 95% of metastatic colorectal cancers are defined as DNA mismatch repair proficient (pMMR). Our previous study found that miR-6511b-5p was downregulated in pMMR colorectal cancer. However, the mechanism of miR-6511b-5p in pMMR colorectal cancer metastases remain unclear.

Methods
We first used quantitative real-time PCR to evaluate the role of miR-6511b-5p in colorectal cancer. Second, we conducted invasion assays and wound healing assays to investigate the role of miR-6511b-5p and CD44 in colorectal cancer cells metastases. Third, luciferase reporter assay, in situ hybridization (ISH), and immunohistochemistry assays were performed to study the relationship between miR-6511b-5p and BRG1. Finally, real-time quantitative PCR, immunohistochemistry, and chromatin immunoprecipitation (ChIP) assays were performed to analyze the relationship between BRG1 and CD44 in colorectal cancer.

Results
We found that lower expression of miR-6511b-5p appeared more often in pMMR colorectal cancer patients compared with dMMR (mismatch repair deficient) cases, and was positively correlated with metastases. In vitro, overexpression of miR-6511b-5p inhibited metastasis by decreasing CD44 expression via directly targeting BRG1 in colorectal cancer. Furthermore, BRG1 knockdown decreased the expression of CD44 by promoting CD44 methylation in colorectal cancer cells.

Conclusion
Our data suggest that miR-6511b-5p may act as a promising biomarker and treatment target for pMMR colorectal cancer, particularly in metastatic patients. Mechanistically, miR-6511b-5p suppresses invasion and migration of colorectal cancer cells through methylation of CD44 via directly targeting BRG1.
Late early to early middle Eocene climate and vegetation change at Tastakh Lake (northern Yakutia, eastern Siberia)
Authors: Bondarenko Olesya V. , Utescher Torsten 
Published: May 2022

AbstractThe late early – early middle Eocene climate and vegetation evolution in northern Yakutia (Eastern Siberia) is quantitatively studied in detail for the first time, based on a palaeobotanical record. Palaeobotanical data for this time interval were obtained from 16 palynofloras from continental sediments on the southern shore of Tastakh Lake (the left bank of Indigirka River). In this first integrative study, we applied the Coexistence Approach for quantification of palaeoclimate, the Plant Functional Type (PFT) approach and Integrated Plant Record (IPR) vegetation analysis to quantify palaeovegetation. Our investigation documents the persistence of warm temperate and, at times, nearly tropical climate conditions in the earlier part of the record and the subsequent onset of a cooling trend. Overall humid climate conditions prevailed throughout the late early – early middle Eocene. Our reconstruction indicates low temperature seasonality and relatively strong seasonality in precipitation. Vegetation data as reconstructed are in good agreement with the climate evolution. PFT diversity spectra indicate the prevalence of mixed evergreen-deciduous forests of warm temperate character. The IPR method suggests that the mixed mesophytic forest biome persisted throughout the studied sedimentary succession. The presence of mangroves in our late early Eocene records (at the base of the section) is largely in line with our climate reconstruction and possibly can be related to the Early Eocene Climatic Optimum (EECO) hyperthermal event.

Published: May 2022

AbstractDirect-powder bed selective laser processing (D-PBSLP) is a promising technique for the manufacturing of complex-shaped parts of Silicon Carbide (SiC) ceramic. In this work, a complex optimization of the process parameters was performed by numerical and experimental analysis. The numerical model was used to determine and optimize the effect of laser power, scanning speed and hatching distance at different layer thicknesses of 20, 30 and 40 µm. Regarding the experimental process parameters study, powder compaction was also studied and optimized. The optimization parameter criteria were to achieve reproducible and high relative density parts. Concerning the experimental manufacturing process, D-PBSLP of alpha-silicon carbide parts with a maximum relative density of 81% were manufactured. Moreover, the process viability can be confirmed with the manufacturing of SiC complex shapes in absence of any additives in the initial powder and without or post-treatment. The results from this study could be used as a guide for process parameters selection.
Representations of women and gender in DFID's development-security-counterterrorism nexus
Authors: Patel Sofia 
Published: May 2022

AbstractIn a post-9/11 environment, the Department for International Development (DFID) shifted its strategic focus towards an integrationist approach that aligned mainstream development programming with the national security agenda. A key part of those reforms was integrating counterterrorism – directly and indirectly – into DFID's portfolio. Using a feminist institutionalist approach, I examine how discourses about women, development, security, and counterterrorism are reproduced through a ‘development-security-counterterrorism nexus’.Within the nexus, DFID represents a key site for the production, reproduction, and evolution of gendered discursivepractices1about women. I argue that institutional evolution is possible through a process of discursive evolution where certain discourses become more or less engrained or ‘sedimented’2depending on the presence of alternative ideas and knowledges. The central research question askshow did gender-sensitive development work evolve after 9/11 and what factors influenced and shaped this evolution? The main findings were that as counterterrorism aims, objectives, and methods became more emphasised in UK development programming, a sense of institutional incoherence and poor strategic direction adversely affected how gender-sensitive programming was designed and implemented. Furthermore, I conclude that gendered development policy was largely based on assumptions rather than evidence, which negatively impacted how programmes were implemented.

Published: May 2022

AbstractTechnology-enabled approaches to conducting 24-h dietary recalls (24HR) may reduce dietary assessment bottlenecks in low-resource settings. However, few studies have assessed their performance relative to conventional pen-and-paper interview (PAPI) approaches and none have validated performance against a benchmark (e.g. weighed food record (WFR)) in a low- and middle-income country (LMIC). This study assessed relative accuracy and cost-effectiveness of INDDEX24, a technology-enabled approach to conducting 24HR, compared with a PAPI approach and against an observer WFR. Women aged 18–49 years from northern Viet Nam (n234) were randomly assigned to be interviewed using INDDEX24 or PAPI 24HR following a WFR. The two one-sidedttest approach assessed the equivalence of each recall modality to the benchmark. Difference-in-differences analysis compared the recall-benchmark results across modalities. Cost per percentage point of accuracy for INDDEX24 and PAPI was derived from accuracy results and the cost to conduct the 24HR. The PAPI and INDDEX24 24HR were statistically equivalent to the WFR for all nutrients except vitamin A. INDDEX24 diverged significantly less than PAPI from the WFR for Fe (0·9v.−1·3 mg) and PAPI diverged less for protein (–3·7v.7·9 g). At the individual level, 26 % of PAPI and 32 % of INDDEX24 respondents had energy intakes within +/– 10 % of the WFR. INDDEX24 cost $111 004 and the PAPI cost $120 483 (USD 2019), making INDDEX24 more cost-effective across most indicators. INDDEX24 was an accurate and cost-effective method for assessing dietary intake in the study context and represents a preferred alternative to PAPI 24HR in Viet Nam and other LMIC.
C'est juste une blague ! Vraiment ? Quand l'humour et la religion alimentent les stéréotypes
Authors: Choquette Emmanuel 
Published: May 2022

RésuméÀ partir d'une expérience s’étant déroulée au Québec auprès de plus de 200 personnes, cet article évalue dans quelle mesure l'humour peut alimenter les stéréotypes culturels et religieux. Si sur le plan des effets directs, les différences s'avèrent moins importantes, on remarque que le degré de participation religieuse joue un rôle significatif dans l'entretien d'une perception négative à l’égard des immigrants et de la communauté arabo-musulmane. Ce constat souligne la nécessité de considérer des facteurs modérateurs pour mesurer les impacts des diverses manifestations de la communication politique, dont l'humour, sur certaines attitudes liées à la diversité.
Spatiotemporal co-occurrence of predators and prey in a neotropical mammal community in southern Mexico

Published: May 2022

AbstractPredator-prey interactions are one of the central themes in ecology due to their importance as a key mechanism in structuring biotic communities. In the predator-prey systems, the behaviours of persecution and avoidance impact on the ecosystem dynamics as much as the trophic interactions. We aimed to analyse the spatiotemporal co-occurrences between prey and predators in a community of medium- and large-sized mammals in southern Mexico. We predict prey will avoid sites where a predator previously passed. Contrarily, we expect a search behaviour by predators and a synchronization in activity patterns among them. We found prey does not occur either in time or space where predators have passed, suggesting an avoidance behaviour. Contrary to our expectations, we did not find significant search behaviours from predators to prey. Synchronization in the daily temporal overlap between predators was higher (Δ = 0.77–0.82) than with their prey (Δ = 0.43 – 0.81). The results suggest prey perceives the risk of predation and displays avoidance behaviour both spatially and temporally, which is consistent with the fear theory. This study provides a complementary approach to understanding the behaviour mechanism between predators and prey through camera-trapping or similar data of spatiotemporal co-occurrences.
Tracking liquid savings at Pompeii: the coin hoard data
Authors: Bowes Kim 
Published: May 2022

AbstractThis article examines the newly published data on coin hoards from Pompeii, focusing on coins and other objects found on victims, and hoards from so-called savings boxes. Most of the work on savings or capital in the Roman world has focused on the size and composition of elite fortunes and the nature and extent of credit and monetization writ large. The article uses the Pompeii coin data set to examine the extent and nature of liquid savings held by a broader section of the population, including a substantial portion of non-elites. In doing so, it also makes some suggestions about the socioeconomic identity of those who failed to escape the town during the eruption.

AbstractObjectiveDignity therapy (DT) is a brief psychotherapeutic intervention with beneficial effects in the end-of-life experience. Since it provides a continuing bond between the bereaved and their loved ones, we speculated that it could be offered as a novel bereavement intervention following the patient's death. We aimed to develop, translate, and validate the Posthumous DT Schedule of Questions (p-DT-SQ), for administration with bereaved relatives or friends.MethodThe original DT-SQ was adapted for application with bereaved relatives or friends. It was translated and back-translated to European Portuguese and revised by an expert committee. Content validity was assessed by the Content Validity Coefficient (CVC). The instrument was tested in a sample of 50 individuals from a large Senior Residence in Lisbon (10 elderly people and 40 healthcare professionals), who assessed face validity.ResultsThe p-DT-SQ showed very good CVC (0.94) and face validity: it was considered clear, easy to understand, reasonable in length, and not difficult to answer. Participants felt comfortable answering the p-DT-SQ and felt it could positively affect the way themselves or others would remember their loved ones, allowing an understanding of the deceased's concerns, interests, and values.Significance of resultsWe created and validated an adapted version of the DT-SQ to be used posthumously by bereaved family and friends. The European Portuguese version of the p-DT-SQ is clear, comprehensible, and aligned with the fundamentals of DT. While our data suggest its beneficial effects for those who are bereft, future research is needed to examine the impact of p-DT-SQ for those who are grieving.
The Heterogeneous Surface of Asteroid (16) Psyche
Authors: Cambioni Saverio , de Kleer Katherine , Shepard Michael 
Published: May 2022

AbstractMain‐belt asteroid (16) Psyche is the largest M‐type asteroid, a class of object classically thought to be the metal cores of differentiated planetesimals and the parent bodies of the iron meteorites. de Kleer, Cambioni, and Shepard (2021, https://doi.org/10.3847/psj/ac01ec) presented new data from the Atacama Large Millimeter Array (ALMA), from which they derived a global best‐fit thermal inertia and dielectric constant for Psyche, proxies for regolith particle size, porosity, and/or metal content, and observed thermal anomalies that could not be explained by surface albedo variations only. Motivated by this, here we fit a model to the same ALMA data set that allows dielectric constant and thermal inertia to vary across the surface. We find that Psyche has a heterogeneous surface in both dielectric constant and thermal inertia but, intriguingly, we do not observe a direct correlation between these two properties over the surface. We explain the heterogeneity in dielectric constant as being due to variations in the relative abundance of metal and silicates. Furthermore, we observe that the lowlands of a large depression in Psyche's shape have distinctly lower thermal inertia than the surrounding highlands. We propose that the latter could be explained by a thin mantle of fine regolith, fractured bedrock, and/or implanted silicate‐rich materials covering an otherwise metal‐rich surface. All these scenarios are indicative of a collisionally evolved world.

AbstractMass wasting plays an important role in carbon cycling and sequestration by exposing fresh bedrock and delivering hillslope sediments to lowlands and fluvial systems. Chemical weathering signatures of landslide‐derived fluvial sediments can be used to understand linkages between hillslope and fluvial processes and thus to characterize spatiotemporal dynamics of sediments. However, chemical signatures of fluvial sediments derived by landslides are yet to be fully understood. Here, we compare the bulk chemistry, mineralogy, and grain size of fluvial sediments collected pre‐ and post‐Hurricane Maria in the Rio Guayanés and Rio Guayabo watersheds in southeastern Puerto Rico to help fill this knowledge gap. Comparison of the mud fraction (<63 μm) of fluvial sediments collected before Hurricane Maria with similar mud fractions collected after the storm reveals that the post‐hurricane muds exhibit a wider range and higher average weathering index values, but coarser grain size modes. We infer that small landslides triggered by Hurricane Maria transported slope materials from shallow depths, including weathered topsoil and saprolite, as opposed to previous deep‐seated landslides, which likely sampled regolith and bedrock. Variances in weathering indices observed that pre‐ and post‐hurricanes do not necessarily reflect average climate signatures, but rather reflect subtle differences in a transport mechanism, which produce significant differences in weathering indices recorded by fluvial sediments. We propose that weathering indices provide a means to understand sediment dynamics in mountainous regions, particularly for sediment transported immediately after landslides triggered by extreme events, such as precipitation and earthquakes, and also provide important data sets required for mapping potential carbon sequestration across landscapes.

AbstractGeomagnetically Induced Currents (GICs) arise from spatio‐temporal changes to Earth's magnetic field, which arise from the interaction of the solar wind with Earth's magnetosphere, and drive catastrophic destruction to our technologically dependent society. Hence, computational models to forecast GICs globally with large forecast horizon, high spatial resolution and temporal cadence are of increasing importance to perform prompt necessary mitigation. Since GIC data is proprietary, the time variability of the horizontal component of the magnetic field perturbation (dB/dt) is used as a proxy for GICs. In this work, we develop a fast, global dB/dt forecasting model, which forecasts 30 min into the future using only solar wind measurements as input. The model summarizes 2 hr of solar wind measurement using a Gated Recurrent Unit and generates forecasts of coefficients that are folded with a spherical harmonic basis to enable global forecasts. When deployed, our model produces results in under a second, and generates global forecasts for horizontal magnetic perturbation components at 1 min cadence. We evaluate our model across models in literature for two specific storms of 5 August 2011 and 17 March 2015, while having a self‐consistent benchmark model set. Our model outperforms, or has consistent performance with state‐of‐the‐practice high time cadence local and low time cadence global models, while also outperforming/having comparable performance with the benchmark models. Such quick inferences at high temporal cadence and arbitrary spatial resolutions may ultimately enable accurate forewarning of dB/dt for any place on Earth, resulting in precautionary measures to be taken in an informed manner.
