AbstractIn the context of bereavement, little is known about the mechanisms that differentiate normative adjustment patterns from those that may indicate potential psychopathology. This study aimed to replicate and extend previous work by (1) characterizing the trajectories of depressive symptoms from 3 to 12 months after the loss of a spouse, (2) examining whether (a) childhood maltreatment and attachment style predicted distinct depression trajectories, and (b) different depression trajectories were associated with the risk of prolonged grief at 12 months post‐loss. Recently bereaved individuals (N = 175) completed self‐report assessments at 3, 4, 6, and 12‐months post‐loss. Trajectories of depressive symptoms were estimated using group‐based trajectory modelling. Four distinct trajectories of depressive symptoms were identified: (1) resilience (minimal/no depression across time points; 45%), (2) moderate depression‐improved (alleviated to ‘mild’ by 12 months; 31%), (3) severe depression‐improved (alleviated to ‘moderate’ by 12 months; 15%), and (4) chronic depression (‘severe’ symptoms across time points; 9%). Higher childhood maltreatment predicted a greater likelihood of belonging to the ‘severe depression‐improved’ and ‘chronic depression’ groups than the ‘resilient’ and ‘moderate depression‐improved’ groups. Widow(er)s with higher attachment anxiety were more likely to belong to the ‘severe depression‐improved’ and ‘chronic depression’ groups than the ‘resilient’ group. The trajectory groups with persistent levels of depressive symptoms up until 6 months were more likely to exhibit prolonged grief at 12 months post‐loss. Changes from pre‐loss functioning cannot be estimated. Our findings provide insight into the early identification of post‐loss prolonged grief.
Hunting for talent: Firm‐driven labor market search in the United States
Authors: Black Ines , Hasan Sharique , Koning Rembrand 
Published: November 2023

AbstractResearch SummaryWe analyze firm‐driven labor market search, where firms “hunt” for talent rather than rely on workers to apply for vacancies. We leverage three approaches. We develop a model of firm‐driven search and derive equilibrium conditions under which firms use this channel. We test our model's predictions using two data sources. Data from a nationally representative survey of 10,000 workers shows that the percentage hired through recruiting has increased from 4.9% in 1991 to 14.3% in 2022. This share is larger for higher‐skilled workers and those with online profiles on LinkedIn. We complement this analysis with data on the near universe of online job postings from 2010 through 2020. Consistent with our model and worker survey evidence, we find firms that demand higher‐skilled workers or operate in labor markets with heavy LinkedIn use are more likely to “hunt for talent.”Managerial SummaryWe study the phenomenon of “hunting” for talent, where firms fill open positions by searching for workers and inviting them to a recruiting process, rather than relying on workers to apply directly. We find that the percentage of workers hired through hunting has increased from 4.9% in 1991 to 14.3% in 2022. We propose that firms that rely more on high‐skilled workers and/or operate within industries with a higher share of available candidates with online profiles are more likely to hunt for their talent. We find support for this conjecture using two data sets, documenting the worker and firm side of the labor market. Data from a nationally representative survey of 10,000 workers shows they are more likely to have been “hunted” by their employer if they work in an occupation that requires more skills, or if their industry has more candidates with online profiles. Moreover, data on US‐wide job postings over the past decade shows that firms in need of highly skilled workers are more likely to invest in outbound recruiting capabilities.
The role of information in the gender gap in the market for top managers: Evidence from a quasi‐experiment
Authors: Tsolmon Ulya 
Published: November 2023

AbstractResearch SummaryThis study examines the role of information in the gender gap in the executive labor market from the market frictions perspective. I ask whether increases in objective and reliable information about managerial quality close the gender gap in career advancements. To obtain exogenous variation in the availability of information, I exploit a natural experiment provided by the adoption of the International Financial Reporting Standards (IFRS) in 2005 by the European Union countries. I find that when reliable and objective information is more available, women executives are more likely to be hired away with promotion than men, especially from high‐performing firms. However, the gains in advancement rates are dampened in regions where societal views on women in the workplace are less favorable.Managerial SummaryBridging opportunity gaps for underrepresented groups remains a significant challenge for firms and policymakers. This research investigates the role of transparent financial disclosures by firms in closing the gender gap in executive promotions. Utilizing the adoption of the IFRS in EU countries, the study finds that women executives are more likely to be hired away with promotion than men, especially from high‐performing firms. However, less favorable societal views about working women weaken these effects. The study suggests that firms can leverage informational asymmetry in the labor market to access high‐quality managerial resources. Concurrently, firms must be cognizant of how financial regulations may affect their competitive edge in the executive talent market and adjust their internal retention policies accordingly.

AbstractResearch SummaryThe paradox of rejecting novel ideas while being motivated to select them exists in many realms. Deviating from prior research that investigated several internal levers to promote the funding of novel ideas in the sciences, we focus on an external lever by investigating how seconded employees increase the selection of novel ideas in two ways: (1) they select more novel ideas themselves, and (2) they influence permanent employees to do the same. Combining unique quantitative longitudinal data and 37 in‐depth interviews, we test our predictions in the secondment program at the National Science Foundation and find broad support for our theoretical arguments. Our findings have implications for scholars of science and innovation by proposing a relatively light‐touch intervention to facilitate the selection of novel ideas.Managerial SummaryOrganizations often face a paradox: they want to select novel ideas but tend to reject them. This study shifts focus from internal measures to an external solution, examining how seconded employees can help. Through both quantitative data and interviews at the National Science Foundation's secondment program, we found that seconded employees choose more novel ideas and influence permanent staff to do the same. This suggests a simple intervention can significantly boost the acceptance of innovative ideas, offering valuable insights for those in the science and innovation. Understanding this dynamic can empower managers to strategically leverage seconded employees, fostering a more innovative and adaptive organizational culture.

Published: November 2023

AbstractTo reduce electromagnetic interference and noise pollution within communication base stations and servers, it is necessary for electromagnetic wave absorption (EWA) materials to transition from coating to multifunctional devices. Up to now, the stable and effective integration of multiple functions into one material by a simple method has remained a large challenge. Herein, a foam‐type microwave absorption device assembled with multicomponent organic matter and graphite powder is synthesized by a universal combination process. Melamine and phenolic aldehyde amine work as the skeleton and cementing compound, respectively, in which graphite is embedded in the cementing compound interconnected into the mesoscopic 3D electric conductive and heat conductive network. Interestingly, the prepared flexible graphite/melamine foam (CMF) delivers a great EWA performance, with a great effective absorption bandwidth of 9.8 GHz, ultrathin thickness of 2.60 mm, and a strong absorption reflection loss of −41.7 dB. Moreover, the CMF possesses porosity and flexibility, endowing it with sound absorption ability. The CMF is unique in its integration of EWA, heat conduction, sound absorption, and mechanical robustness, as well as its cost‐effective and scalable manufacturing. These attributes make CMF promising as a multifunctional device widely used in communication base stations, servers, and chips protection.

AbstractHerein, a facile strategy is illustrated to develop pyrolysis‐free out‐of‐plane coordinated single atomic sites‐based M‐POP via a one‐pot Friedel Craft acylation route followed by a post‐synthetic metalation. The optimized geometry of the Co@BiPy‐POP clearly reveals the presence of out‐of‐plane Co‐single atomic sites in the porous backbone. This novel photopolymer Co@BiPy‐POP shows extensive π‐conjugations followed by impressive light harvesting ability and is utilized for photochemical CO2 fixation to value‐added chemicals. A remarkable conversion of styrene epoxide (STE) to styrene carbonate (STC) (≈98%) is obtained under optimized photocatalytic conditions in the existence of promoter tert‐butyl ammonium bromide (TBAB). Synchrotron‐based X‐ray adsorption spectroscopy (XAS) analysis reveals the single atom coordination sites along with the metal (Co) oxidation number of +2.16 in the porous network. Moreover, in situ diffuse reflectance spectroscopy (DRIFTS) and electron paramagnetic resonance (EPR) investigations provide valuable information on the evolution of key reaction intermediates. Comprehensivecomputational analysis also helps to understand the overall mechanistic pathway along with the interaction between the photocatalyst and reactants. Overall, this study presents a new concept of fabricating porous photopolymers based on a pyrolysis‐free out‐of‐plane‐coordination strategy and further explores the role of single atomic sites in carrying out feasible CO2 fixation reactions.

Published: November 2023

AbstractPorous carbon is widely used in energy storage‐conversion systems, and the question of how to explore an efficient strategy for preparation is very significant. Herein, the flame retardant capability of (NH4)2SO4/Mg(OH)2 that contains gas phase‐heat absorption‐condensate phase components is assisted to carbonize coal tar pitch in air and obtain the porous carbon. The mechanism of stepwise inflaming retarding is systematically investigated. In the carbonization process in a muffle furnace, (NH4)2SO4 decomposes releasing gases at below 400 °C to act as the role of gas phase flame retardant. Mg(OH)2 starts to decompose at ≥ 400 °C, and it has the effect of heat absorption and condensed phase flame retardation (MgSO4 and MgO). What's more, the flame retardant also serves as an N, S source and template. The obtained porous carbon possesses an ultrahigh carbon yield of 56.9 wt.%, hierarchical pore structure, and multi‐heteroatoms doping. It can still reach up to 244.7 F g−1 even loaded 20 mg of active material. In addition, the (NH4)2SO4/agar gel electrolyte is synthesized, and the fabricated flexible ammonium ion capacitor exhibits a superior energy density of 40.8 Wh kg−1. This work uncovers a new way to construct porous carbon, which is expected to synthesize more carbon materials using other carbon sources.

Published: November 2023

AbstractThe spin states of active sites have a significant impact on the adsorption/desorption ability of the reaction intermediates during the oxygen evolution reaction (OER). Sulfide spinel is not generally considered a highly efficient OER catalyst owing to the low spin state of Co3+ and the lack of unpaired electrons available for adsorption of reaction intermediates. Herein, it is proposed a novel Nd‐evoked valence electronic adjustment strategy to engineer the spin state of Co ions. The unique f‐p‐d orbital electronic coupling effect stimulates the rearrangement of Co d orbital electrons and increases the eg electron filling to achieve high‐spin state Co ions, which promotes charge transport by propagating a spin channel and generates a high number of active sites for intermediate adsorption. The optimized CuCo1.75Nd0.25S4 catalyst exhibits outstanding electrocatalytic properties with a low overpotential of 320 mV at 500 mA cm−2 and a 48 h stability at 300 mA cm−2. In situ synchrotron radiation infrared spectra confirm the quick accumulation of key *OOH and *O intermediates. This work deepens the comprehensive understanding of the relationship between OER activity and spin configurations of Co ions and offers a new design strategy for spinel compound catalysts.

Published: November 2023

AbstractNb4C3Tx MXene has shown extraordinary promise for various applications owing to its unique physicochemical properties. However, it can only be synthesized by the traditional HF‐based etching method, which uses large amounts of hazardous HF and requires a long etching time (> 96 h), thus limiting its practical application. Here, an ultra‐efficient and environmental‐friendly H2O‐assisted supercritical etching method is proposed for the preparation of Nb4C3Tx MXene. Benefiting from the synergetic effect between supercritical CO2 (SPC‐CO2) and subcritical H2O （SBC‐H2O）, the etching time for Nb4C3Tx MXene can be dramatically shortened to 1 h. The as‐synthesized Nb4C3Tx MXene possesses uniform accordion‐like morphology and large interlayer spacing. When used as anode for Li‐ion battery, the Nb4C3Tx MXene delivers a high reversible specific capacity of 430 mAh g−1 at 0.1 A g−1, which is among the highest values achieved in pure‐MXene‐based anodes. The superior lithium storage performance of the Nb4C3Tx MXene can be ascribed to its high conductivity, fast Li+ diffusion kinetics and good structural stability.

Published: November 2023

AbstractDiisononyl phthalate (DINP) and di(isononyl)cyclohexane‐1,2‐dicarboxylate (DINCH) are plasticizers introduced to replace previously used phthalate plasticizers in polymeric products. Exposure to DINP and DINCH has been shown to impact lipid metabolism. However, there are limited studies that address the mechanisms of toxicity of these two plasticizers. Here, a comparative toxicity analysis has been performed to evaluate the impacts of DINP and DINCH on 3T3‐L1 cells. The preadipocyte 3T3‐L1 cells were exposed to 1, 10, and 100 μM of DINP or DINCH for 10 days and assessed for lipid accumulation, gene expression, and protein analysis. Lipid staining showed that higher concentrations of DINP and DINCH can induce adipogenesis. The gene expression analysis demonstrated that both DINP and DINCH could alter the expression of lipid‐related genes involved in adipogenesis. DINP and DINCH upregulated Pparγ, Pparα, C/EBPα Fabp4, and Fabp5, while both compounds significantly downregulated Fasn and Gata2. Protein analysis showed that both DINP and DINCH repressed the expression of FASN. Additionally, we analyzed an independent transcriptome dataset encompassing temporal data on lipid differentiation within 3T3‐L1 cells. Subsequently, we derived a gene set that accurately portrays significant pathways involved in lipid differentiation, which we subsequently subjected to experimental validation through quantitative polymerase chain reaction. In addition, we extended our analysis to encompass a thorough assessment of the expression profiles of this identical gene set across 40 discrete transcriptome datasets that have linked to diverse pathological conditions to foreseen any potential association with DINP and DINCH exposure. Comparative analysis indicated that DINP could be more effective in regulating lipid metabolism.

Abstract6‐benzylaminopurine (6‐BA), a multifunctional plant growth regulator, which is frequently used worldwide to improve qualities of various crops, is an important ingredient in production of “toxic bean sprouts.” Although there is no direct evidence of adverse effects, its hazardous effects, as well as joint toxicity with other chemicals, have received particular attention and aroused furious debate between proponents and environmental regulators. By use of human umbilical vein endothelial cells (HUVECs), adverse effects of 6‐BA to human‐derived cells were first demonstrated in this study. A total of 25–50 mg 6‐BA/L inhibited proliferation, migration, and formation of tubular‐like structures by 50% in vitro. Results of Western blot analyses revealed that exposure to 6‐BA differentially modulated the MAPK signal transduction pathway in HUVECs. Specifically, 6‐BA decreased phosphorylation of MEK and ERK, but increased phosphorylation of JNK and P38. In addition, 6‐BA exacerbated atorvastatin‐induced cerebral hemorrhage via increasing hemorrhagic occurrence by 60% and areas by 4 times in zebrafish larvae. In summary, 6‐BA elicited toxicity to the endothelial system of HUVECs and zebrafish. This was due, at least in part, to discoordination of MAPK signaling pathway, which should pose potential risks to the cerebral vascular system.

AbstractAerobic glycolysis plays an important role in multidrug resistance of cancer cells. Here, we screened different expressed lncRNAs associated with sorafenib resistance of liver cancer cells, by intersecting the bioinformatics analyses of TCGA and GEO (the GSE62813 dataset) databases. Our results revealed that the 18 upregulated lncRNAs in the intersection are associated with and enriched in metabolism of small molecule organic acids, suggesting their potential in glycolysis. The lncRNA small nucleolar RNA host gene 1 (Snhg1) was chosen as a potential regulator of aerobic glycolysis in liver cancer cells, for its significant promotion on lactate production. Gain‐ and loss‐of‐function experiments mediated by Crispr‐Cas9 technique in HepG2 cells indicated that Snhg1 promoted cell proliferation, invasion, sorafenib resistance, and aerobic glycolysis. In the mechanism exploration, we found that Snhg1 can interact with SND1 protein, a famous RNA binding protein and recently identified “Reader” of N6‐methyladenosine (m6A). SND1 was demonstrated to be positively regulated by Snhg1 and had similar promoting effects on proliferation, invasion, sorafenib resistance, and aerobic glycolysis of HepG2 cells. SND1 bound with and promoted the expression of SLC7A11, an aerobic glycolysis regulator. Furthermore, either silencing SLC7A11 or blocking aerobic glycolysis with 2‐deoxy‐d‐glucose (2‐DG) was able to reverse the promotion of Snhg1 overexpression on malignancy, sorafenib resistance, and aerobic glycolysis of HepG2 cells. Finally, in a liver cancer xenograft mouse model, we found that formed tumors with Snhg1‐knocked‐down HepG2 cells were more sensitive to sorafenib administration. Altogether, SNHG1 contributes to sorafenib resistance of liver cancer cells by promoting SND1‐m6A‐SLC7A11‐mediated aerobic glycolysis.
