AbstractMineralogy and texture of diagenetic phases in the Aptian Pre‐Salt Barra Velha Formation are described, quantified and compared by facies and structural setting to understand their spatial and temporal distribution, and to develop predictive concepts for their genesis. This study examined data from eight wells from one oil‐field in the Santos Basin. Calcite is the most abundant mineral and occurs with fibro‐radial texture as spherulites and shrubs and sparse microcrystalline mudstone. The δ18O values from calcite spherulites and shrubs suggest water of similar composition and temperature, but they have different δ13C values. Mudstones show lower δ18O, suggesting warmer lake water and/or lower evaporation, whereas δ13C values indicate a variable, but commonly strong influence of biogenic CO2. Dolomite with rhombohedral habit was the first to precipitate, followed by lamellar, saddle and anhedral varieties. Rhombohedral dolomites show a positive δ13C‐δ18O correlation and a similar range in values to spherulites and shrubs, suggesting similar lake water. The lamellar dolomite is related to biofilms, whereas anhedral dolomite is attributed to mixing of pore and meteoric waters. Lamellar and anhedral dolomites have similar isotopic values, precipitating after rhombohedral dolomite in slightly warmer and/or less evaporatively concentrated pore water. Saddle dolomite is related to hydrothermal fluids that percolated the formation during early diagenesis. Silica occurs as replacement of primary calcite and Mg‐clay, but also as a cement and more rarely as a depositional chert. Both dolomite and silica display a complex range of petrographic textures, many of which are facies dependent. This study focusses on the most important phases of the paragenetic sequence that took place pre‐burial and are (1) formation of Mg‐clay, calcite spherulites and shrubs, (2) partial dolomitisation of shrubs and spherulites and precipitation of rhombohedral and lamellar dolomites, (3) precipitation of saddle dolomite, matrix and carbonate dissolution and (4) anhedral dolomite and all textures of precipitated or substituted silica.

AbstractHomicide, suicide, or accident – elemental intoxication may be a cause in each of these types of deaths. Inductively coupled plasma mass spectrometry (ICP‐MS) has emerged as the gold standard analytical method for toxic metal analysis in both clinical and forensic settings. An ICP‐MS method was developed using a modified acidic workup for the quantitative determination of arsenic, lead, and thallium. Method validation focused on the assessment of linearity, between‐ and within‐day precisions, limits of detection (LoD) and lower limits of quantification (LLoQ), and carryover. The method was applied to analysis of postmortem peripheral blood samples from 279 forensic cases for which orders for chemical–toxicological examination had been received from the public prosecutor's office. Using six‐point and one‐point calibrations (latter for rapid screening purposes), precisions and accuracies ranged from −4.8 to 5.8% and −6.4 to 7.5%. Analytical sensitivities for As, Pb, and Tl were 0.08, 0.18, and 0.01 μg/l (LoD) and 0.23, 0.66, and 0.03 μg/l (LLoQ), respectively. Observed postmortem peripheral blood concentrations were As, 1.31 ± 3.42 μg/L; Pb, 17.4 ± 13.1 μg/L; and Tl, 0.11 ± 0.07 μg/L (mean ± standard deviation [SD]). Elemental concentrations, determined in additional quality control samples, were in good agreement to those obtained with an external ICP‐MS method based on alkaline sample processing. The current method is practicable and compatible with an ICP‐MS system used for trace element analysis in an accredited medical laboratory. It allows for implementation of low‐threshold investigations when metal intoxications are suspected in forensic routine.

AbstractThe toxicity and chemical instability shortcomings of lead halide perovskites are major concerns that continue to motivate the search for next generation alternatives. Copper halides are known to be lead‐free, earth‐abundant, low‐cost, and environmentally friendly, and affordable in optoelectronic performance due to their bright luminescence, tunable emission wavelength, and excellent stability. However, the controlled synthesis of low‐dimensional copper halide nanocrystals (NCs) with near‐unity photoluminescence quantum yield (PLQY) and high stability remains a great challenge. In this work, we report a reasonable optimization approach for the preparation of Cs3Cu2Cl5 NCs by hot‐injection colloidal synthesis technology. Specifically, the Cs3Cu2Cl5 NCs synthesized with MnC2O4 as the defect repair agent exhibited negligible self‐absorption, bright green luminosity with PL emission at about 535 nm and PLQY can be increased from 68.7 % to 100 %. The Cs3Cu2Cl5 NCs shows excellent stability and outstanding optical properties, and is expected to be used as highly efficient green light emitter in high‐efficiency X‐ray scintillator.
Global sensitivity and domain‐selective testing for functional‐valued responses: An application to climate economy models
Authors: Fontana Matteo , Tavoni Massimo , Vantini Simone 
Published: June 2024

AbstractUnderstanding the dynamics and evolution of climate change and associated uncertainties is key for designing robust policy actions. Computer models are key tools in this scientific effort, which have now reached a high level of sophistication and complexity. Model auditing is needed in order to better understand their results, and to deal with the fact that such models are increasingly opaque with respect to their inner workings. Current techniques such as Global Sensitivity Analysis (GSA) are limited to dealing either with multivariate outputs, stochastic ones, or finite‐change inputs. This limits their applicability to time‐varying variables such as future pathways of greenhouse gases. To provide additional semantics in the analysis of a model ensemble, we provide an extension of GSA methodologies tackling the case of stochastic functional outputs with finite change inputs. To deal with finite change inputs and functional outputs, we propose an extension of currently available GSA methodologies while we deal with the stochastic part by introducing a novel, domain‐selective inferential technique for sensitivity indices. Our method is explored via a simulation study that shows its robustness and efficacy in detecting sensitivity patterns. We apply it to real‐world data, where its capabilities can provide to practitioners and policymakers additional information about the time dynamics of sensitivity patterns, as well as information about robustness.

AbstractDespite a growing movement towards expanding computer science education in PreK‐12, gaps in computing opportunities along lines of race, ethnicity, class, and gender have widened. Emergent theories and practices related to culturally responsive computing show promise in addressing this gap; however, little is known about engaging Black, Latinx, and Indigenous preschoolers in computer science. In this paper, we utilized qualitative content analyses to explore how an early childhood computer science curriculum created opportunities for young Black and Latinx preschoolers to develop computational thinking skills while engaging in culturally responsive computing. Overwhelmingly, we found the curriculum, co‐developed with educators and caregivers, emphasized unplugged tools and coding activities to support computational thinking. These unplugged opportunities positioned children as innovators with technology and technosocial change agents, in developmentally‐appropriate, play‐based ways. Findings demonstrate a need to emphasize the value of unplugged tools and coding activities in order to support computational thinking and align the goals of culturally responsive computing with the unique needs of young children. We discuss implications for a theory of culturally responsive computing specifically for early childhood education.

AbstractNutritional intervention can greatly benefit people who suffer from side effects of medical treatments by improving intestinal post‐damage recovery. The recovery process is dependent on the regeneration of intestinal epithelial cells, which is driven by Lgr5+ intestinal stem cells (ISCs). Lactoferrin (LF) is a natural milk‐abundant protein with several gut health‐related functions such as antibacterial and immunoregulation activities, thus protecting intestine from damage. However, it is unclear whether LF also plays a role in the repair of the injured intestine, despite limited clues on its ability to modulate intestinal epithelial cell growth in vitro. Here, we show that LF accelerates intestinal epithelial recovery after both dextran sulfate sodium challenge on mice and TNF‐α treatment on intestinal organoids. Furthermore, we find LF gives rise to ISC‐mediated epithelial regeneration by directly activating the Lgr5+ stem cells. Finally, we identify Lrp5/Wnt signaling as the key pathway for LF‐enhancing ISC stemness and function. Overall, our study reveals the potential of LF as a nutrient that can be applied to promote intestinal healing.
Tracing the Digital Plant Humanities: Narratives of Botanical Life and Human‐Flora Relations
Authors: Arthur Paul Longley , Ryan John Charles 
Published: June 2024

AbstractIn this paper, we trace the emergence of what we term the digital plant humanities (DPH) as an evolution of burgeoning botanical interest among environmental and digital humanists. We argue that DPH coalesces the theoretical and methodological frameworks of the three research areas of plant humanities, environmental humanities, and digital humanities. After conceptualising DPH, we analyse three projects representative of the emergent field—the Native American Ethnobotany Database; Herbaria 3.0; and Microcosms: A Homage to Sacred Plants of America—while referring to a broader range of formative projects including the Plant Humanities Lab.
Exposure to thiourea during the early stages of development impedes the formation of the swim bladder in zebrafish larvae

AbstractThiourea, a widely used agrochemical, is known to inhibit the activity of thyroid peroxidase, a key enzyme in the biosynthetic pathway of thyroid hormones. Thyroid insufficiency compromises the basal metabolic rate in warm‐blooded organisms and embryonic development in vertebrates. In this study, we looked for developmental defects by exposing the zebrafish embryos to an environmentally relevant dose of thiourea (3 mg/mL). Liquid chromatography–tandem mass spectrometry (LC‐MS/MS) was performed to validate thiourea's presence in the treated zebrafish embryos. Structural anomalies like bent tail and pericardial edema were noticed in 96‐h post‐fertilization (hpf) larvae. On histological examination, underdeveloped swim bladder was noticed in 96 hpf larvae exposed to 3 mg/mL thiourea. The treated larvae also failed to follow the characteristic swimming behavior in response to stimuli due to defective swim bladder. Swim bladder being homologous to the lung of tetrapod, the role of Bmp4, a major regulator of lung development, was studied along with the associated regulatory genes. Gene expression analysis revealed that thiourea administration led to the downregulation of bmp4, shh, pcna, anxa5, acta2, and the downstream effector snail3 but the upregulation of caspase3. The protein expression showed a similar trend, wherein Bmp4, Shh, and Pcna were downregulated, but Cleaved Caspase3 showed an increased expression in the treated group. Therefore, it is prudent to presume that exposure to thiourea significantly reduces the expression of Bmp4 and other key regulators; hence, the larvae fail to develop a swim bladder, a vital organ that regulates buoyancy.
The mixed blessing of work connectivity demands: Self‐regulatory focus as a moderator
Authors: Nie Qi , Lim Vivien K. G. , Peng Jian 
Published: June 2024

SummaryDue to the rapid development of information and communication technologies, employees increasingly feel pressure to engage in work connectivity behavior after regular working hours (WCBA), giving rise to a novel form of job demand known as WCBA demands. This research examined the upside and downside of WCBA demands. Specifically, we defined WCBA demands as stressors that can be appraised by employees as challenges and/or threats. Challenge appraisals are related to job involvement, which in turn leads to job satisfaction and job performance; threat appraisals are related to job‐induced tension, which in turn leads to family dissatisfaction and family incivility. We also examine regulatory focus as a boundary condition underlying the challenge‐threat paradox of WCBA demands. To test the relationships among our hypotheses, we conducted a daily diary survey study of 176 employee‐supervisor‐spouse triads across five consecutive workdays. The findings show that employees with higher levels of promotion focus were more likely to appraise WCBA demands as challenges, which improved their work outcomes via increased job involvement. Employees with higher levels of prevention focus appraised WCBA demands as threats, which undermined their family outcomes via job‐induced tension. Since these findings assume that WCBA demands act as stressors, we conducted a supplemental qualitative study (N = 19) confirming that employees commonly perceive WCBA demands as stressors. The implications for theory and research are discussed.

ABSTRACTPrior studies suggest a multifaceted relationship between creativity and psychopathology, indicating that mild psychopathology might enhance creative behavior. Moreover, similar brain regions may be implicated in both creativity and psychosis. Although aberrant salience (AS) is often associated with psychotic disorders, it could also enhance creative capabilities. This study assesses salience alterations among healthy individuals, artists, and patients with psychosis to investigate its influence on creativity. Three groups were studied: 196 healthy controls, 50 artists from Florence Academy of Fine Arts, and 84 outpatients with a diagnosis of psychosis. They were assessed with the Aberrant Salience Inventory (ASI). We compared ASI scores among the groups using ANOVA, followed by post‐hoc t‐tests, and adjusted the scores for age, gender, and education through ANCOVA. The ANOVA revealed significant differences in ASI scores among the groups, with artists displaying notably higher ASI scores than both controls and patients. ANCOVA confirmed that group membership was a significant factor influencing ASI scores, while age, gender, and education were not. Additionally, antipsychotic treatment did not significantly impact ASI scores among patients. Rather than an unequivocal marker of pathology, AS might also be interpreted as an anthropological asset, enhancing creative faculties alongside unique perceptual experiences. Education may help individuals in channeling their AS mechanisms through art.

Abstract

Local knowledge is an essential dimension of humanity's relationship with the environment. Investigating the interdependence between humans and wild birds holds value in fostering a mutually beneficial relationship with avian populations.

Gathering bird eggs is a significant practice for Kihnu islanders in Estonia. There are very few studies of this age‐old, complex knowledge that assess the topic from the perspective of the local community. This paper investigates the reciprocity and the relationality between people and birds and the position of commons in the local community practice of bird semi‐domestication.

Several methods (interviews, participant observation and literature study) were used in data collection. We obtained information on local knowledge concerning 58 bird taxa. Locals named at least 21 bird species from which they have collected eggs. While collecting eggs is a central activity, the relationship surrounding egg collection is far more intricate. Locals take care of nesting boxes in Common Merganser which birds reside, collecting only a few eggs from every box. These nesting boxes are also constructed for passerine birds. Furthermore, caring for birds influences the soundscape of Kihnu and significantly impacts the cultural bond between local communities and the birds. Kihnu islanders are mindful of the changes occurring in the bird population.

The intimate relationship between local people and birds is challenged when traditional ways of life are restricted by stricter nature conservation norms (e.g. banning the collection of bird eggs and visiting islets). However, birdlife is very important in ensuring biocultural diversity. Therefore, this study proposes several important future perspectives in promoting the sustainable development of rural life: (1) the introduction of pluralistic nature protection, including the opinion of local communities in the management of natural resources; (2) the promotion of birds as a means of pest control; and (3) reinforcing the reciprocal coexistence of birds and humans on Kihnu. We advocate for community‐centred nature management which takes into consideration Local Ecological Knowledge and its attached expertise, shared responsibility and benefits, sustainable development trajectories and local community‐based governance systems.

Published: June 2024

AbstractPoly(lactic acid) (PLA) grafted glycidyl neodecanoate (GND) with a single epoxy group (PLA‐GND) is prepared in this paper by solid phase grafting, and the effects of different reaction conditions on the grafting percentage of PLA‐GND are investigated. Furthermore, PLA‐GND is used as a nonreactive compatibilizer to prepare PLA‐GND/PLA/poly(butylene adipate‐co‐terephthalate) (PBAT) composite by melt blending. The results show that PLA‐GND has the highest grafting percentage of 2.15% when the feed weight ratio of GND to PLA is 0.2, the feed weight ratio of triphenylphosphine to PLA is 0.02, the additive amount of xylene is 1 mL, the reaction temperature is 120°C, and the reaction time is 115 min. The GND segments of PLA‐GND and PBAT segments could form a physical entanglement microdomain because of the similar aliphatic chain of GND and PBAT, which would improve the compatibility of PLA and PBAT. PLA‐GND/PLA/PBAT composite has the highest tensile strength, elongation at break, impact strength, crystallinity, heat deformation temperature, and melt flow rate at a PLA‐GND content of 5%, which are 38.54 MPa, 118.65%, 15.83 kJ/m2, 5.71%, 65.3°C, and 36.3 g/10 min, 14.53%, 390.90%, 68.94%, 224.43%, 16.19%, and 224.40% higher than those of PLA/PBAT composite, respectively.Highlights

Published: June 2024

AbstarctPsychodynamic constructs and psychopathology are closely inter‐related, but more detailed insight is needed. We investigated these complex inter‐relations using network analysis. A Gaussian graphical model in a sample of N = 2232 psychotherapeutic inpatients was estimated. Self‐administered questionnaires to assess interpersonal relations (Inventory of Interpersonal Problems‐32), psychodynamic conflicts (Operationalized Psychodynamic Diagnosis–Conflict Questionnaire), personality functioning (Operationalized Psychodynamic Diagnosis–Structure Questionnaire‐Short Form, Inventory of Personality Organization‐Short Form), and psychopathology (Brief Symptom Inventory) were utilized. We investigated the network structure, identified the most inter‐related psychodynamic constructs and the psychodynamic constructs with the strongest inter‐relations to psychopathology, and explored the clustering of all included constructs. Active and passive conflict processing modes were negatively inter‐related in most conflicts. Passive conflict processing modes were more strongly related to psychopathology than active ones in all conflicts, apart from the care versus autarky conflict. Identity diffusion shared the strongest inter‐relations within psychodynamic constructs. The psychodynamic constructs that were most strongly related to psychopathology were impairments in self‐perception and the passive self‐worth conflict. Psychopathology and psychodynamic constructs formed distinct clusters. Our results emphasize the relevance of personality functioning within psychodynamic constructs and in relation to psychopathology.
