Caught between academic calling and academic pressure? Working time characteristics, time pressure and time sovereignty predict PhD students’ research engagement
Authors: van Tienoven Theun Pieter , Glorieux Anaïs , Minnen Joeri , Spruyt Bram 
Published: September 2023

AbstractPhD students come to work in academic environments that are characterized by long working hours and work done on non-standard hours due to increasing job demands and metric evaluation systems. Yet their long working hours and work at non-standard hours are often seen as a logical consequence of their intellectual quest and academic calling and may even serve as a proxy for their research engagement. Against that background, quantitative data from 514 PhD students were used to unravel the complex relationships between different aspects of time use and PhD students’ work engagement. While the results support the academia as a calling thesis to some extent, they also show that the relationships between long and non-standard working hours and research engagement are partly negated by the fact that the same working time characteristics lead to perceived time pressure and lack of time sovereignty, which in turn negatively affects their engagement. Moreover, the mechanism behind this negation varies across scientific disciplines. These subjective working time characteristics are the same alarm signals that are flagged as risk factors in academic staff for occupational stress, burnout, and work-life imbalance and thus cannot be ignored.
Attachment Security with Mothers and Fathers: A Meta-Analysis on Mean-Level Differences and Correlations of Verbal Attachment Measures
Authors: Pinquart Martin 
Published: September 2023

AbstractAs mothers and fathers remain important attachment figures beyond infancy and toddlerhood, comparisons of attachment security of older children with their mothers and fathers are relevant for family researchers and practitioners. We analyzed mean-level differences between verbal reports of attachment security with mothers and fathers, and correlations between both attachments. A systematic search in electronic databases identified 826 studies that were included in random-effects meta-analyses. Although security of attachment with fathers was, on average, lower than security of attachment with mothers, mean-level differences were small (g = −0.29). Large correlations were found between security with mothers and fathers (r = 0.53). While mean-level differences were larger in studies with questionnaires rather than interviews, the reverse was found when analyzing correlation. The size of mean-level differences increased with age, while the size of the correlation between security with mothers and fathers declined. More recent studies found smaller mean-level differences and larger correlations of security with both attachment figures. There were smaller differences between security with mothers and fathers as well as larger correlations of security with both parents if samples included more intact families. Mean level-differences were smaller and correlations were stronger if studies included more males. Finally, there were larger correlations of security with mothers and fathers in low-risk samples than in clinical/high-risk samples. We conclude that correlations and mean-level differences of self-reported attachment security are stronger than in studies with behavioral measures of observed security in younger children. Further research is recommended on factors that explain the observed correlations and mean-level differences.
Temperature alters the toxicological impacts of plant terpenoids on the polyphagous model herbivore Vanessa cardui

Published: September 2023

AbstractTerpenes are a major class of secondary metabolites present in all plants, and long hypothesized to have diversified in response to specific plant-herbivore interactions. Herbivory is a major biotic interaction that plays out across broad temporal and spatial scales that vary dramatically in temperature regimes, both due to climatic variation across geographic locations as well as the effect of seasonality. In addition, there is an emerging understanding that global climate change will continue to alter the temperature regimes of nearly every habitat on Earth over the coming centuries. Regardless of source, variation in temperature may influence herbivory, in particular via changes in the efficacy and impacts of plant defensive chemistry. This study aims to characterize temperature-driven variation in toxicological effects across several structural classes of terpenes in the model herbivore Vanessa cardui, the painted lady butterfly. We observed a general increase in monoterpene toxicity to larvae, pupa, and adults at higher temperatures, as well as an increase in development time as terpene concentration increased. Results obtained from this study yield insights into possible drivers of seasonal variation in plant terpene production as well as inform effects of rising global temperatures on plant-insect interactions. In the context of other known effects of climate change on plant-herbivore interactions like carbon fertilization and compensatory feeding, temperature-driven changes in plant chemical defense efficacy may further complicate the prediction of climate change impacts on the fundamental ecological process of herbivory.

Movement computation of an articulated body using coordinate transformation
Authors: Park Jihun 
Published: September 2023

AbstractIn this paper, we propose a new formula for calculating the motion of an articulated rigid body using images obtained with a moving camera with an autofocus ability. Each of the input image scenes consists of moving joints with their own position and orientation unknown. Based on the computed coordinate system of the previous joint, the triangulation method finds the position of the feature point, and the computed feature point establishes the coordinate system for the next adjacent joint. First, the external and internal parameters of a camera are calculated using the optimization technique using the feature points in fixed environmental objects. The first joint is defined as the joint in contact with the environment. Based on the first joint, the movements of subsequent joints are computed in order. Afterwards, we calculate the motion for the connected joint with respect to the previous joint in a tree structure. To verify the accuracy of the movement of a model, a three-dimensional reconstruction was performed by using computed joint movements. The proposed formula is verified by the result of 3D reconstruction.
Three-Dimensional Integrated Geo-Static Modeling for Prospect Identification and Reserve Estimation in the Middle Miocene Multi-Reservoirs: A Case Study from Amal Field, Southern Gulf of Suez Province

Published: September 2023

AbstractMiddle Miocene reservoirs in the southern part of the Gulf of Suez province are characterized by geometrical uncertainties due to their structural settings, lateral facies change, different lithologies, and diverse reservoir quality. Therefore, in this study, detailed 3D geo-static models were constructed by integrating multiple datasets, including 2D seismic sections and digital well-logs. The 3D models were constructed for the Belayim Formation (Hammam Faraun Member), Kareem Formation (Markha Member), and Rudies Formation (Upper Rudies Member) with detailed structuration, zonation, and layering for Amal Field in the southern Gulf of Suez province to assess the hydrocarbon potential, calculate accurate reserves, recommend development and exploration plans, and propose locations for future drilling. The resultant structural model exhibited a compartmentalized area of major and minor normal faults trending NW–SE, forming structurally high potential hydrocarbon trapping locations in the study area. The petrophysical models indicated the good potentiality of Hammam Faraun as a reservoir with porosity values of 15–23%, increasing towards the central part of the area, volume of shale (Vsh) of 21–31%, water saturation (Sw) of 34–49%, and sand thickness increasing toward the northeastern part of the area. The Markha Member was also interpreted as a good reservoir, with porosity values of 15–22%, increasing towards the southeastern part of the area, Vsh of 13–29%, Sw of 16–38%, and sandy facies accumulating in the central horst block. Upper Rudies exhibits good reservoir properties with porosity values of 16–23%, Vsh of 29–37%, Sw of 35–40%, and good sandy facies in the central horst block of the area. The study results showed hydrocarbon potential in the central horst block of the study area for the Middle Miocene multi-reservoirs.
The first negative Fourier coefficient of an Eisenstein series newform
Authors: Carrillo Santana Sebastián 
Published: September 2023

AbstractThere have been a number of papers on statistical questions concerning the sign changes of Fourier coefficients of newforms. In one such paper, Linowitz and Thompson gave a conjecture describing when, on average, the first negative sign of the Fourier coefficients of an Eisenstein series newform occurs. In this paper, we correct their conjecture and prove the corrected version.
Getting off to a good start: emerging academic fields and early-stage equity financing
Authors: Esposito Ciro D. , Szatmari Balazs , Sitruk Jonathan M. C. , Wijnberg Nachoem M. 
Published: September 2023

AbstractPrior studies show that access to academic knowledge plays a crucial role in new venture financing. We extend this research by shifting the focus from the access to academic knowledge to the developmental state of the academic field, where the academic knowledge is generated. Using natural language processing (NLP), we clustered peer-reviewed academic knowledge from Scopus into various fields. We then analyzed a sample of 341 new biotech ventures from Crunchbase to determine if increased past activity by (1) academics and (2) early-stage venture investors in a particular academic field is associated with the early-stage equity financing of new ventures associated with that field. We found that new ventures associated with academic fields for which academic activity has grown in the past receive more early-stage equity capital. However, contrary to our expectations, we also revealed that when a particular academic field shows greater early-stage venture investments in the past, the amount of early-stage equity capital received by subsequent ventures associated with the same academic field decreases. This suggests that while emerging academic fields signal the presence of business opportunities with high reward potential, past increase in the number of investments by peer early-stage investors associated with a particular academic field signals the opposite.
Extreme value modeling with errors-in-variables in detection and attribution of changes in climate extremes
Authors: Lau Yuen Tsz Abby , Wang Tianying , Yan Jun , Zhang Xuebin 
Published: September 2023

AbstractThe generalized extreme value (GEV) regression provides a framework for modeling extreme events across various fields by incorporating covariates into the location parameter of GEV distributions. When the covariates are subject to errors-in-variables (EIV) or measurement error, ignoring the EIVs leads to biased estimation and degraded inferences. This problem arises in detection and attribution analyses of changes in climate extremes because the covariates are estimated with uncertainty. It has not been studied even for the case of independent EIVs, let alone the case of dependent EIVs, due to the complex structure of GEV. Here we propose a general Monte Carlo corrected score method and extend it to address temporally correlated EIVs in GEV modeling with application to the detection and attribution analyses for climate extremes. Through extensive simulation studies, the proposed method provides an unbiased estimator and valid inference. In the application to the detection and attribution analyses of temperature extremes in central regions of China, with the proposed method, the combined anthropogenic and natural signal is detected in the change in the annual minimum of daily maximum and the annual minimum of daily minimum.

Published: September 2023

AbstractFirearm-related interpersonal violence is a leading cause of death and injury in cities across the United States, and understanding the movement of firearms from on-the-books sales to criminal end-user is critical to the formulation of gun violence prevention policy. In this study, we assemble a unique dataset that combines records for over 380,000 crime guns recovered by law enforcement in California (2010–2021), and more than 126,000 guns reported stolen, linked to in-state legal handgun transactions (1996–2021), to describe local and statewide crime gun trends and investigate several potentially important sources of guns to criminals, including privately manufactured firearms (PMFs), theft, and “dirty” dealers. We document a dramatic increase over the decade in firearms recovered shortly after purchase (7% were recovered within a year in 2010, up to 33% in 2021). This corresponds with a substantial rise in handgun purchasing over the decade, suggesting some fraction of newly and legally acquired firearms are likely diverted from the legal market for criminal use. We document the rapid growth of PMFs over the past 2–3 years and find theft plays some, though possibly diminishing, role as a crime gun source. Finally, we find evidence that some retailers contribute disproportionately to the supply of crime guns, though there appear to be fewer problematic dealers now than there were a decade ago. Overall, our study points to temporal shifts in the dynamics of criminal firearms commerce as well as significant city variation in the channels by which criminals acquire crime guns.
Next-Generation Sequencing—Optimal Sequencing of Therapies in Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL)
Authors: Simon Florian , Bohn Jan-Paul 
Published: September 2023

Abstract
Purpose of Review
This research paper aims to provide an overview of evidence-based sequencing of therapies in relapsed/refractory chronic lymphocytic leukemia (CLL) in the era of targeted drugs.

Recent Findings
In the absence of data from randomized clinical trials comparing novel agents head-to-head, growing evidence suggests that patients with late relapse (> 2 years) after fixed-duration therapies benefit from identical retreatment, whereas a class switch is favorable in those with short-lived remissions or progressive disease on continuous drug intake. Treatment of patients previously exposed to both covalent inhibitors of BTK and BCL2 remains an unmet medical need. Novel drugs, in particular noncovalent BTKI, show promising efficacy in this difficult-to-treat subgroup in early clinical trials.

Summary
The optimal sequencing of therapies in CLL requires consideration of individual patient factors and disease characteristics. Double-refractory disease continuous to pose a clinical challenge with a focus on participation in clinical trials whenever possible.

Abstract
Objective
To know the risk of endometrial cancer (EC) in a population of women with BRCA 1/2 pathogenic or likely pathogenic variants after risk-reducing salpingo-oophorectomy (RRSO).

Methods
The study cohort included data from 857 women with BRCA mutations who underwent RRSO visited four hospitals in Catalonia, Spain, from January 1, 1999 to April 30, 2019. Standardized incidence ratio (SIR) of EC was calculated in these patients using data from a regional population-based cancer registry.

Results
After RRSO, eight cases of EC were identified. Four in BRCA 1 carriers and four in BRCA2 carriers. The expected number of cases of EC was 3.67 cases, with a SIR of 2.18 and a 95% CI (0.93–3.95).

Conclusions
In our cohort, the risk of EC in BRCA1/2 carriers after RRSO is not greater than expected. Hysterectomy is not routinely recommended for these patients.

Abstract
Background
Adolescent smoking is associated with significant health and social risks. Previous research has demonstrated the effectiveness of interventions based on behavior change theories in preventing adolescent smoking uptake. However, evidence from the theory-based perspective of evaluation is limited, especially for how such complex interventions work, and how they work when implemented in different contextual settings.

Method
A comparative qualitative analysis was conducted to explore various influences on behavior change among participants taking part in two smoking prevention interventions in Northern Ireland and Bogotá. Twenty-seven focus groups were conducted in 12 schools (6 in Northern Ireland and 6 in Bogota, n = 195 pupils participated; aged 11–15 years). The Theoretical Domains Framework guided a content analysis of the data.

Results
We found similarities across settings in terms of knowledge, skills, and beliefs related to smoking or vaping behavior change, as well as differences in contextual resources and social influence. Different environmental resources included availability to purchase tobacco products in the neighborhoods and previous information about tobacco risk. Participants in both interventions perceived behavioral change outcomes related to personal skills and intention to not smoke or vape.

Conclusion
These findings have highlighted how both individual factors and contextual resources influence behavior change for smoking prevention in practice. Local contextual factors and social influences affecting pupils should be taken into account in the implementation and evaluation of health behavior change interventions. In particular, this study supports using social and contextual influence strategies in interventions to reduce the onset of adolescent smoking and vaping.
Tools for microbial single-cell genomics for obtaining uncultured microbial genomes
Authors: Hosokawa Masahito , Nishikawa Yohei 
Published: September 2023

AbstractThe advent of next-generation sequencing technologies has facilitated the acquisition of large amounts of DNA sequence data at a relatively low cost, leading to numerous breakthroughs in decoding microbial genomes. Among the various genome sequencing activities, metagenomic analysis, which entails the direct analysis of uncultured microbial DNA, has had a profound impact on microbiome research and has emerged as an indispensable technology in this field. Despite its valuable contributions, metagenomic analysis is a “bulk analysis” technique that analyzes samples containing a wide diversity of microbes, such as bacteria, yielding information that is averaged across the entire microbial population. In order to gain a deeper understanding of the heterogeneous nature of the microbial world, there is a growing need for single-cell analysis, similar to its use in human cell biology. With this paradigm shift in mind, comprehensive single-cell genomics technology has become a much-anticipated innovation that is now poised to revolutionize microbiome research. It has the potential to enable the discovery of differences at the strain level and to facilitate a more comprehensive examination of microbial ecosystems. In this review, we summarize the current state-of-the-art in microbial single-cell genomics, highlighting the potential impact of this technology on our understanding of the microbial world. The successful implementation of this technology is expected to have a profound impact in the field, leading to new discoveries and insights into the diversity and evolution of microbes.
Hydrochemistry and water quality of shallow groundwater in the Tikrit area of Salah Al Din Province, Iraq

Published: September 2023

AbstractSalah Al-Din Provence is an active agriculture and population region. One of its primary water sources is groundwater, which suffers from a lack of information regarding water quality and hydrochemistry. In order to study those missing variables, 27 samples from wells of shallow tubes were collected for analyzing the relevant physicochemical indices that help to produce the Schoeller index, Piper diagram, and Gibbs plot. Piper diagram revealed a hydrochemistry behavior of different values along with the groundwater samples. The chemistry of wells was controlled primarily by the evaporation process according to the Gibbs plot. The values of the Schoeller index of the studied samples stated that 59% of them have disequilibrium in Chloro-Alkaline due to their negative obtained values while the rest of them produced positive estimates, which indicates an exchange reaction of cation–anion basic domination. It was concluded that carbonate and silicate weathering, as well as evaporation, controlled the region’ s hydrochemistry. Using Water Quality Index, groundwater was evaluated for use as drinking water. While using Sodium Adsorption Ratio, Sodium percentage, Residual Sodium Carbonate, Magnesium Hazard, and US salinity diagram were all used for estimating the same water’ s suitability for irrigation. All of those indicators, as well as the Gibbs ratio, show that all 27 samples were unsuitable for both studied usage. In addition, those results indicate that evaporation is a major problem for groundwater in this area. Finally, using cluster analysis it was concluded that there are two types of similarities that indicate different levels of pollution in groundwater.
