Complement Clauses and Complementation Strategies
Authors: Dixon R M W
Published: November 2023

A complement clause is a type of clause which fills an argument slot in the structure of another clause. Most languages have a restricted set of complement-taking verbs (CTVs) which may have either an NP—as in (i) and (3) from English—or a complement clause—as in (2) and (4)—corresponding to a core argument slot.
A Man Called Henri: Truth, Reconciliation, and Justice
Authors: Sachs Justice Albie
Published: November 2023

I was in my chambers when I received a message from reception that somebody calling himself ‘Henri’ had arrived to see me. I went to the security entrance with a measure of anticipation. Henri had telephoned a few days earlier to say that he was going to testify to the Truth and Reconciliation Commission about the bomb which had exploded in my car and caused the loss of my right arm. Naturally I was keen to see the person who had the courage, or the foolhardiness, or just the interest, to want to see me.

Published: November 2023

Research in human volunteers and surgical patients has shown that unconsciousness under general anesthesia can be reliably tracked using real-time electroencephalogram processing. Hence, a closed-loop anesthesia delivery (CLAD) system that maintains precisely specified levels of unconsciousness is feasible and would greatly aid intraoperative patient management. The US Federal Drug Administration has approved no CLAD system for human use due partly to a lack of testing in appropriate animal models. To address this key roadblock, we implement a nonhuman primate (NHP) CLAD system that controls the level of unconsciousness using the anesthetic propofol. The key system components are a local field potential (LFP) recording system; propofol pharmacokinetics and pharmacodynamic models; the control variable (LFP power between 20 and 30 Hz), a programmable infusion system and a linear quadratic integral controller. Our CLAD system accurately controlled the level of unconsciousness along two different 125-min dynamic target trajectories for 18 h and 45 min in nine experiments in two NHPs. System performance measures were comparable or superior to those in previous CLAD reports. We demonstrate that an NHP CLAD system can reliably and accurately control in real-time unconsciousness maintained by anesthesia. Our findings establish critical steps for CLAD systems’ design and testing prior to human testing.

Published: November 2023

Online social media foster the creation of active communities around shared narratives. Such communities may turn into incubators for conspiracy theories—some spreading violent messages that could sharpen the debate and potentially harm society. To face these phenomena, most social media platforms implemented moderation policies, ranging from posting warning labels up to deplatforming, i.e. permanently banning users. Assessing the effectiveness of content moderation is crucial for balancing societal safety while preserving the right to free speech. In this article, we compare the shift in behavior of users affected by the ban of two large communities on Reddit, GreatAwakening and FatPeopleHate, which were dedicated to spreading the QAnon conspiracy and body-shaming individuals, respectively. Following the ban, both communities partially migrated to Voat, an unmoderated Reddit clone. We estimate how many users migrate, finding that users in the conspiracy community are much more likely to leave Reddit altogether and join Voat. Then, we quantify the behavioral shift within Reddit and across Reddit and Voat by matching common users. While in general the activity of users is lower on the new platform, GreatAwakening users who decided to completely leave Reddit maintain a similar level of activity on Voat. Toxicity strongly increases on Voat in both communities. Finally, conspiracy users migrating from Reddit tend to recreate their previous social network on Voat. Our findings suggest that banning conspiracy communities hosting violent content should be carefully designed, as these communities may be more resilient to deplatforming.

Published: November 2023

Plants produce specialized metabolites with defensive properties that are often synthesized through the coordinated regulation of metabolic genes by transcription factors in various biological contexts. In this study, we investigated the regulatory function of the transcription factor PhERF1 from petunia (Petunia hybrida), which belongs to a small group of ETHYLENE RESPONSE FACTOR (ERF) family members that regulate the biosynthesis of bioactive alkaloids and terpenoids in various plant lineages. We examined the effects of transiently overexpressing PhERF1 in petunia leaves on the transcriptome and metabolome, demonstrating the production of a class of specialized steroids, petuniolides, and petuniasterones in these leaves. We also observed the activation of many metabolic genes, including those involved in sterol biosynthesis, as well as clustered genes that encode new metabolic enzymes, such as cytochrome P450 oxidoreductases, 2-oxoglutarate-dependent dioxygenases, and BAHD acyltransferases. Furthermore, we determined that PhERF1 transcriptionally induces downstream metabolic genes by recognizing specific cis-regulatory elements in their promoters. This study highlights the potential of evolutionarily conserved transcriptional regulators to induce the production of specialized products through transcriptional reprogramming.

Authors: Danişman Murat , Dursun Gökay , Koçyiğit İsmail Aykut , Yilgor Caglar , Aksoy Mehmet Cemalettin
Published: November 2023

Background:

Although Dega acetabuloplasty is widely used for the treatment of developmental dysplasia of the hip, there is a paucity of data on long-term outcomes. The purpose of the study was to evaluate the rate of residual acetabular dysplasia after Dega acetabuloplasty.

Methods:

Patients of a previously reported consecutive series of 35 patients (43 hips) operated by a single surgeon were recontacted for long-term follow-up. Of these, 25 patients (32 hips) consented, with a follow-up rate of 71% (74% of hips). The mean age at the time of surgery was 35 (18 to 65) months. The presence of residual dysplasia was noted according to the lateral center-edge angle of Wiberg, femoral head extrusion index, and Tönnis angle. The latest radiographic outcome was evaluated according to the Severin classification and patients were clinically evaluated according to the modified McKay criteria.

Results:

The mean follow-up duration of 16.5 (12 to 20) years yielded an average age of 19.2 (14 to 23) years at the time of analysis. According to lateral center-edge angle, femoral head extrusion index, and Tönnis angle, 5 (15.6%) hips were dysplastic and 2 (6.3%) hips were reoperated for resubluxation. Thus, a total of 7 hips (21.9%) were considered to have residual dysplasia. With the exception of 2 hips that underwent further osteotomies, no other hips were re-subluxated or redislocated. Overcoverage was noted in 6 (18.7%) hips. There were 26 Severin group I and II (81.3%), 4 Severin group III (12.5%), and 2 Severin group IV (6.2%) hips. According to modified McKay criteria, 20 (62.5%) hips were excellent, 7 (21.9%) hips were good, and 5 (15.6%) were fair. Severin classification and modified McKay criteria were correlated with dysplasia (P < 0.05).

Conclusions:

Seventy-eight percent of the hips treated by Dega acetabuloplasty for developmental dysplasia of the hip did not have acetabular dysplasia at a mean follow-up of 16 years. Even in well-treated asymptomatic hips, patients should be followed regularly, especially for residual dysplasia.

Level of Evidence:

Level IV.
Emergency Treatment of Acute Decompensated Severe Aortic Stenosis with Transcatheter Aortic Valve Implantation under the Coplane View Using J-Tipped Wires Fluoroscopy
Authors: Liu Xian , Wang Yingdong , Sheng Yuhe , Wang Bin , Xu Kai
Published: November 2023

Patients experiencing severe aortic stenosis with acute decompensation often face elevated surgical aortic valve replacement risks, leading to high postoperative mortality rates. However, for some patients eligible for transcatheter aortic valve implantation (TAVI), computed tomography angiography for assessing the aortic root and coronary artery might be challenging before the TAVI procedure. This case highlights a patient who underwent emergency TAVI guided by coplane view generated using J-tipped wires fluoroscopy without computed tomography evaluation before the TAVI. This approach reduces contrast usage during the TAVI procedure, significantly mitigating the risks of renal injury and heart function deterioration.
Impact of Social Disparities on 5-Year Survival Rates in Pediatric Hematologic Malignancies
Authors: Chalfant Victor , Riveros Carlos , Bechtel Allison , Bradfield Scott M. , Stec Andrew A.
Published: November 2023

Background:

Socioeconomic disparities exist in pediatric patients with hematologic malignancies, leading to suboptimal survival rates. Social determinants of health impact health outcomes, and in children, they may not only lead to worse survival outcomes but carry over into late effects in adult life. The social deprivation index (SDI) is a composite score using geographic county data to measure social determinants of health. Using the SDI, the purpose of the present study is to stratify survival outcomes in pediatric patients with hematologic malignancies based on area deprivation.

Methods:

A retrospective cohort study was performed using the national Surveillance, Epidemiology, and End Results oncology registry in the USA from 1975 to 2016 based on county-level data. Pediatric patients (≤18 y old) with a diagnosis of leukemia or lymphoma based on the International Classification for Oncology, third edition (ICD-O-3) were used for inclusion criteria. Patients were grouped by cancer subtype for leukemia into acute lymphoblastic leukemia (ALL) and acute myeloid leukemia while for lymphoma into non-Hodgkin’s lymphoma and Hodgkin’s lymphoma. SDI scores were calculated for each patient and divided into quartiles, with Q1 being the lowest area of deprivation and Q4 being the highest, respectively.

Results:

A total of 38,318 leukemia and lymphoma patients were included. Quartile data demonstrated stratification in survival based on area deprivation for ALL, with no survival differences in the other cancer subtypes. Patients with ALL from the most deprived area had a roughly 3% difference in both overall and cancer-specific morality at 5 years compared with the least deprived area.

Conclusion:

Disparities in pediatric patients with ALL represent a significant area for quality improvement. Social programs may have value in improving survival outcomes and could rely on metrics such as SDI.
Identification of a valuable gene network for the diagnosis and treatment of non-obstructive azoospermia: in-silico analyses – experimental research
Authors: Zabihi Mohammad Reza , Norouzkhani Narges , Karkhah Samad , Akhoondian Mohammad
Published: November 2023

Introduction:

Non-obstructive azoospermia (NOA) is an etiology of infertility in men. NOA may have various classifications; however, hypogonadotropic hypogonadism can be regarded as a class of NOA associated with genetic factors. Former studies have shown that noncoding RNA (ncRNA) plays an essential role in NOA incidence, but few studies have been performed on the NOA-related ncRNA interaction network. In the current study, genes, NOA-related microRNA (miRNA), and circular RNA (circRNA) were found by bioinformatics methods to offer a new perspective on NOA treatment.

Methods:

The gonadotropin-releasing hormone receptor (GnRHR)-related protein–protein interaction (PPI) network was extracted by searching in ‘string-database’. GO, KEGG, and Enrichr databases were used to identify pathways, molecular function, and biological processing. Four databases, including TargetScan, mirDIP, miRmap, and miRWalk, were used to extract miRNAs. At last, the circ2GO, circBase, and literature were used to identify circRNAs and their genes.

Results:

The current study identified the four proteins associated with the GnRHR signaling; eight shared miRNAs that affect the expression of found proteins and 25 circRNAs and their origin genes that regulate the miRNAs’ function.

Conclusion:

The two miRNAs, hsa-miR-134-3p and hsa-miR-513C-3p, the three genes, VCAN, NFATC3, and PRDM5, and their associated circRNAs can perform as a valuable gene network in the diagnosis and treatment of NOA pathogenesis.
Clinical indications and outcomes of Impella devices for severe cardiogenic shock in COVID-19 patients: a systematic review
Authors: Srichawla Bahadar S. , Kipkorir Vincent , Sekhon Manraj
Published: November 2023

Background:

Coronavirus disease 2019 (COVID-19) can present with significant cardiac dysfunction, including cardiogenic shock. Mechanical circulatory support with an Impella device may be utilized in these patients to support and offload native right ventricle (RV) and left ventricle (LV) functions. This systematic review aims to describe clinical indications, management, laboratory data, and outcomes in patients with severe cardiogenic shock from COVID-19 treated with an Impella device.

Methods:

A PRISMA-directed systematic review was performed and prospectively registered in PROSPERO. The databases accessed included PubMed/MEDLINE, Scopus, and ScienceDirect. Quality and risk of bias assessments were completed using the Joanna Briggs Institute (JBI) checklist for case reports.

Results:

A total of 16 records were included in the qualitative synthesis; 8/16 (50%) of the patients were men. The average age was 39 years (SD: 14.7). The biventricular Impella (BiPella) approach was recorded in 3/16 (18.75%) patients. A total of 4/16 (25%) individuals required renal replacement therapy (RRT). Single-device usage was observed in three cases: 2/16 Impella CP (12.5%) and 1/16 Impella RP (6.25%). Treatment of COVID-19 myocarditis included a wide range of antivirals and immunomodulators; 8/16 (50%) cases needed ECMO (extracorporeal membrane oxygenation) support. Overall, only 2/16 (11.7%) individuals died.

Conclusions:

Sixteen reported individuals have received an Impella implanted with a mortality rate of 11.7%. Concurrent use of RRT and ECMO implantation was often observed. Overall, the Impella device is an effective and safe strategy in the management of COVID-19-related cardiogenic shock. Future studies should include long-term results.
Early Discharge after Uncomplicated Elective Colectomy and Risk of Postdischarge Complication
Authors: Balas Michael , Quereshy Fayez , Bohnen Jordan , Jung James J
Published: November 2023

BACKGROUND:

This was a retrospective cohort study of adult patients undergoing uncomplicated elective colectomy using the NSQIP database from January 2012 to December 2019. A colectomy is deemed uncomplicated if there are no complications reported during the hospitalization. The objective of this study was to examine the association between discharge timing and postdischarge complications in patients who undergo uncomplicated elective colectomy.

STUDY DESIGN:

Patients were stratified into an early discharge group if their length of postoperative hospitalization was ≤3 days for laparoscopic or robotic approaches, or ≤5 days for the open approach, and otherwise into delayed discharge groups. The association between early discharge and any postdischarge complication was examined using unadjusted logistic regression after propensity score matching between early and delayed discharge groups.

RESULTS:

Of the 113,940 patients included, 77,979, 15,877, and 20,084 patients underwent uncomplicated laparoscopic, robotic, and open colectomy, respectively. After propensity score matching, the odds of a postdischarge complication were lower for the early discharge group in laparoscopic (odds ratio 0.73, 95% CI 0.68 to 0.79) and robotic (odds ratio 0.63, 95% CI 0.52 to 0.76) approaches, and not different in the open approach (odds ratio 1.02, 95% CI 0.91 to 1.15). There were no clinically meaningful differences in the risk of return to the operating room for all surgical approaches.

CONCLUSIONS:

Early discharge after uncomplicated colectomy appears to be safe and is associated with lower odds of postdischarge complications in minimally invasive approaches. Our findings suggest that surgical teams practice sound clinical judgments on selecting patients who benefit from early discharge.
Space and time on the membrane: modelling Type VI secretion system dynamics as a state-dependent random walk
Authors: Miller Jonathan , Murray Philip J.
Published: November 2023

The type six secretion system (T6SS) is a transmembrane protein complex that mediates bacterial cell killing. The T6SS comprises three main components (transmembrane, baseplate and sheath/tube complexes) that are sequentially assembled in order to enable an attacking cell to transport payloads into neighbouring cells. A T6SS attack disrupts the function of essential cellular components of target cells, typically resulting in their death. While the assembled T6SS adopts a fixed position in the cell membrane of the attacking cell, the location of the firing site varies between firing events. In
Serratia marcescens
, a post-translational regulatory network regulates the assembly and firing kinetics of the T6SS in a manner that affects the attacking cell’s ability to kill target cells. Moreover, when the ability of membrane complexes to reorient is reduced, an attacking cell’s competitiveness is also reduced. In this study, we will develop a mathematical model that describes both the spatial motion and assembly/disassembly of a firing T6SS. The model represents the motion of a T6SS on the cell membrane as a state-dependent random walk. Using the model, we will explore how both spatial and temporal effects can combine to give rise to different firing phenotypes. Using parameters inferred from the available literature, we show that variation in estimated diffusion coefficients is sufficient to give rise to either spatially local or global firers.
Insights into drivers of mobility and cultural dynamics of African hunter–gatherers over the past 120 000 years
Authors: Zonker Johannes , Padilla-Iglesias Cecilia , Djurdjevac Conrad Nataša
Published: November 2023

Humans have a unique capacity to innovate, transmit and rely on complex, cumulative culture for survival. While an important body of work has attempted to explore the role of changes in the size and interconnectedness of populations in determining the persistence, diversity and complexity of material culture, results have achieved limited success in explaining the emergence and spatial distribution of cumulative culture over our evolutionary trajectory. Here, we develop a spatio-temporally explicit agent-based model to explore the role of environmentally driven changes in the population dynamics of hunter–gatherer communities in allowing the development, transmission and accumulation of complex culture. By modelling separately demography- and mobility-driven changes in interaction networks, we can assess the extent to which cultural change is driven by different types of population dynamics. We create and validate our model using empirical data from Central Africa spanning 120 000 years. We find that populations would have been able to maintain diverse and elaborate cultural repertoires despite abrupt environmental changes and demographic collapses by preventing isolation through mobility. However, we also reveal that the function of cultural features was also an essential determinant of the effects of environmental or demographic changes on their dynamics. Our work can therefore offer important insights into the role of a foraging lifestyle on the evolution of cumulative culture.
Analysis of the energy transfer process for multiple scattering problems involving lossy media
Authors: Kalogeropoulos Andreas , Tsitsas Nikolaos L.
Published: November 2023

The energy transfer process for acoustic propagation and scattering in inhomogeneous, lossy media is rigorously investigated. Two problems are considered: an arbitrarily composed cluster of lossy scatterers, excited by a single point source and a layered, lossy medium excited by an internal point-source distribution. Energy conservation laws and optical theorems are established. The connection of active intensity with the scattering cross section and the relation between reactive intensity and Lagrangian density are determined. Furthermore, the influence of the losses of the involved media to the kinetic energy is unveiled. Reductions to lossless media and near-zero frequency values are derived.
Exact hydrodynamics and onset of phase separation for an active exclusion process
Authors: Mason James , Erignoux Clément , Jack Robert L. , Bruna Maria
Published: November 2023

We consider a lattice model of active matter with exclusion and derive its hydrodynamic description exactly. The hydrodynamic limit leads to an integro-differential equation for the density of particles with a given orientation. Volume exclusion results in nonlinear mobility dependent on spatial density. Such models of active matter can support motility-induced phase separation, which occurs despite the absence of attractive interactions. We study the onset of phase separation with linear stability analysis and numerical simulations.

Parental care is considered crucial for the enhanced survival of offspring and evolutionary success of many metazoan groups. Most bryozoans incubate their young in brood chambers or intracoelomically. Based on the drastic morphological differences in incubation chambers across members of the order Cheilostomatida (class Gymnolaemata), multiple origins of incubation were predicted in this group. This hypothesis was tested by constructing a molecular phylogeny based on mitogenome data and nuclear rRNA genes 18S and 28S with the most complete sampling of taxa with various incubation devices to date. Ancestral character estimation suggested that distinct types of brood chambers evolved at least 10 times in Cheilostomatida. In
Eucratea loricata
and
Aetea
spp. brooding evolved unambiguously from a zygote-spawning ancestral state, as it probably did in
Tendra zostericola
, Neocheilostomata, and
‘Carbasea' indivisa
. In two further instances, brooders with different incubation chamber types, skeletal and non-skeletal, formed clades (
Scruparia
spp.,
Leiosalpinx australis
) and (
Catenicula corbulifera
(
Steginoporella
spp. (
Labioporella
spp.,
Thalamoporella californica
))), each also probably evolved from a zygote-spawning ancestral state. The modular nature of bryozoans probably contributed to the evolution of such a diverse array of embryonic incubation chambers, which included complex constructions made of polymorphic heterozooids, and maternal zooidal invaginations and outgrowths.
The gender gap in names of prokaryotes honouring persons
Authors: Freese Heike M. , Giner-Pérez Lola , Oren Aharon , Göker Markus , Arahal David R.
Published: November 2023

The aim of this study is to analyse prokaryotic names which honour persons, eponyms, from a gender perspective. Data were retrieved from the List of Prokaryotic names with Standing in Nomenclature. Excluding new combinations, the etymologies of 23 315 unique names at the rank of genus, species and subspecies were analysed. A total of 2018 (8.7 %) names honour persons (eponyms), for which the development of the female share over time was further investigated. Women started to be honoured very recently (1947) compared to men (1823). Moreover, only 14.8 % of all prokaryotic eponyms refer to females. This ratio has hardly improved since 1947, although the number of women whose contributions to microbiology could have been recognized has increased over time. In contrast, about 50 % of prokaryotic names derived from mythological characters refer to females. To reduce this gender gap, we encourage authors proposing new taxon names to honour female scientists who can serve as role models for new generations.
Remarkably high repeat content in the genomes of sparrows: the importance of genome assembly completeness for transposable element discovery

Published: November 2023

Transposable elements (TE) play critical roles in shaping genome evolution. However, the highly repetitive sequence content of TEs is a major source of assembly gaps. This makes it difficult to decipher the impact of these elements on the dynamics of genome evolution. The increased capacity of long-read sequencing technologies to span highly repetitive regions of the genome should provide novel insights into patterns of TE diversity. Here we report the generation of highly contiguous reference genomes using PacBio long read and Omni-C technologies for three species of sparrows in the family Passerellidae. To assess the influence of sequencing technology on TE annotation, we compared these assemblies to three chromosome-level sparrow assemblies recently generated by the Vertebrate Genomes Project and nine other sparrow species generated using a variety of short- and long-read technologies. All long-read based assemblies were longer in length (range: 1.12-1.41 Gb) than short-read assemblies (0.91-1.08 Gb). Assembly length was strongly correlated with the amount of repeat content, with longer genomes showing much higher levels of repeat content than typically reported for the avian order Passeriformes. Repeat content for the Bell’s sparrow (31.2% of genome) was the highest level reported to date for a songbird genome assembly and was more in line with woodpecker (order Piciformes) genomes. CR1 LINE elements retained from an expansion that occurred 25-30 million years ago were the most abundant TEs in the song sparrow genome. Although the other five sparrow species also exhibit evidence for a spike in CR1 LINE activity at 25-30 million years ago, LTR elements stemming from more recent expansions were the most abundant elements in these species. LTRs were uniquely abundant in the Bell’s sparrow genome deriving from two recent peaks of activity. Higher levels of repeat content (79.2-93.7%) were found on the W chromosome relative to the Z (20.7-26.5) or autosomes (16.1-30.9%). These patterns support a dynamic model of transposable element expansion and contraction underpinning the seemingly constrained and small sized genomes of birds. Our work highlights how the resolution of difficult-to-assemble regions of the genome with new sequencing technologies promises to transform our understanding of avian genome evolution.
Factors influencing customer satisfaction with AR shopping assistant applications in e-commerce: an empirical analysis utilizing text-mining techniques
Authors: Ho Jae-Yun , Ju Gyeong , Hong Seoeui , An Jaeyoung , Lee Choong C.
Published: November 2023

Purpose

This study investigates the key factors that influence customer satisfaction when interacting with augmented reality shopping assistance applications (ARSAPs). ARSAPs grant consumers the capability to experience products in a virtually simulated user environment before product acquisition. With the development of mobile e-commerce due to breakthroughs in smartphone and augmented reality (AR) technologies, there is an increasing potential for these emergent AR mobile services, yet there is a need for further improvement.

Design/methodology/approach

This study initially explored the key satisfaction factors for ARSAPs by utilizing topic modeling of a collection of actual user reviews. These factors are subsequently revisited and complemented by existing literature, and finally verified through logistic regression analysis supported by sentiment analysis.

Findings

This study identified the key factors that influence customer satisfaction with ARSAPs, including visuality, sense of reality, credibility, format, completeness, understandability, relevance, flexibility, response time, reliability, availability, ease of use and privacy. In particular, two additional factors (i.e. visuality and sense of reality) were newly identified as important in the context of AR, despite their previous omissions in existing literature.

Originality/value

This study is the first to investigate the key factors that influence customer satisfaction with ARSAPs from users' perspectives, utilizing topic modeling of a large amount of real-world data on actual user feedback. By identifying new factors (i.e. visuality and sense of reality) that were not identified in previous literature, this study provides important academic implications for a broader understanding of AR and related technologies that are essential elements of the metaverse. This study also provides valuable insights for developers and companies in the e-commerce industry on how to optimize AR applications and develop more targeted and effective marketing strategies in this field.

The ecological footprint of industrial value added and energy consumption in Indonesia
Authors: Kurniawan Robert , Nugroho Novan Adi Adi , Fudholi Ahmad , Purwanto Agung , Sumargo Bagus , Gio Prana Ugiana , Wongsonadi Sri Kuswantono
Published: November 2023

Purpose

The purpose of this paper is to determine the effect of the industrial sector, renewable energy consumption and nonrenewable energy consumption in Indonesia on the ecological footprint from 1990 to 2020 in the short and long term.

Design/methodology/approach

This paper uses vector error correction model (VECM) analysis to examine the relationship in the short and long term. In addition, the impulse response function is used to enable future forecasts up to 2060 of the ecological footprint as a measure of environmental degradation caused by changes or shocks in industrial value-added, renewable energy consumption and nonrenewable energy consumption. Furthermore, forecast error decomposition of variance (FEVD) analysis is carried out to predict the percentage contribution of each variable’s variance to changes in a specific variable. Granger causality testing is used to enhance the analysis outcomes within the framework of VECM.

Findings

Using VECM analysis, the speed of adjustment for environmental damage is quite high in the short term, at 246%. This finding suggests that when there is a short-term imbalance in industrial value-added, renewable energy consumption and nonrenewable energy consumption, the ecological footprint experiences a very rapid adjustment, at 246%, to move towards long-term balance. Then, in the long term, the ecological footprint in Indonesia is most influenced by nonrenewable energy consumption. This is also confirmed by the Granger causality test and the results of FEVD, which show that the contribution of nonrenewable energy consumption will be 10.207% in 2060 and will be the main contributor to the ecological footprint in the coming years to achieve net-zero emissions in 2060. In the long run, renewable energy consumption has a negative effect on the ecological footprint, whereas industrial value-added and nonrenewable energy consumption have a positive effect.

Originality/value

For the first time, value added from the industrial sector is being used alongside renewable and nonrenewable energy consumption to measure Indonesia’s ecological footprint. The primary cause of Indonesia’s alarming environmental degradation is the industrial sector, which acts as the driving force behind this issue. Consequently, this contribution is expected to inform the policy implications required to achieve zero carbon emissions by 2060, aligned with the G20 countries’ Bali agreement of 2022.
Lecturers' interpersonal trust in peers, job performance, and OCBI: examining the mediating role of positive affect during the Covid-19 pandemic utilizing the PLSe2 estimator
Authors: Ghasemy Majid , Frömbling Lena
Published: November 2023

Purpose

Guided by the affective events theory (AET), the purpose of this paper was to explore the impact of interpersonal trust in peers, as an affective work event, on two affect-driven behaviors (i.e. job performance and organizational citizenship behavior toward individuals [OCBI]) via positive affect during the Covid-19 pandemic, particularly in the Asia–Pacific region.

Design/methodology/approach

This study is quantitative in approach, and longitudinal survey study in design. The authors collected data from lecturers in 2020 at the beginning, at the end and two months after the first Covid-19 lockdown in Malaysia. Then, the authors utilized the efficient partial least squares (PLSe2) estimator to investigate the relationships between the variables, while also considering gender as a control variable.

Findings

The findings show that positive affect fully mediates the relationship between interpersonal trust in peers and job performance and partially mediates the relationship between interpersonal trust in peers and OCBI. Given that gender did not demonstrate any significant relationships with interpersonal trust in peers, positive affect, job performance and OCBI, the recommended policies can be universally developed and applied, irrespective of the gender of academics.

Originality/value

This research contributes originality by integrating the widely recognized theoretical framework of AET and investigating a less explored context, specifically the Malaysian higher education sector during the challenging initial phase of the Covid-19 pandemic. Furthermore, the authors adopt a novel and robust methodological approach, utilizing the efficient partial least squares (PLSe2) estimator, to thoroughly examine and validate the longitudinal theoretical model from both explanatory and predictive perspectives.
Diligence, objectivity, quality and accuracy
Authors: Bhattacharya Rajeev R. , Gupta Mahendra R.
Published: November 2023

Purpose

The authors provide a general framework of behavior under asymmetric information and develop indices of diligence, objectivity and quality by an analyst and analyst firm about a studied firm, and relate them to the accuracy of its forecasts. The authors test the associations of these indices with time.

Design/methodology/approach

The test of Public Information versus Non-Public Information Models provides the index of diligence, which equals one minus the p-value of the Hausman Specification Test of Ordinary Least Squares (OLS) versus Two Stage Least Squares (2SLS). The test of Objectivity versus Non-Objectivity Models provides the index of objectivity, which equals the p-value of the Wald Test of zero coefficients versus non-zero coefficients in 2SLS regression of the earnings forecast residual. The exponent of the negative of the standard deviation of the residuals of the analyst forecast regression equation provides the index of analytical quality. Each index asymptotically equals the Bayesian ex post probability, by the analyst and analyst firm about the studied firm, of the relevant behavior.

Findings

The authors find that ex post accuracy is a statistically and economically significant increasing function of the product of the indices of diligence, objectivity and quality by the analyst and analyst firm about the studied firm, which asymptotically equals the Bayesian ex post joint probability of diligence, objectivity and quality. The authors find that diligence, objectivity, quality and accuracy did not improve with time.

Originality/value

There has been no previous work done on the systematic and objective characterization and joint analysis of diligence, objectivity and quality of analyst forecasts by an analyst and analyst firm for a studied firm, and their relation with accuracy. This paper puts together the frontiers of various disciplines.
Multimaterial 3D printing of auxetic jounce bumpers for automotive suspensions
Authors: Giubilini Alberto , Minetola Paolo
Published: November 2023

Purpose

The purpose of this study is to evaluate the 3D printability of a multimaterial, fully self-supporting auxetic structure. This will contribute to expanding the application of additive manufacturing (AM) to new products, such as automotive suspensions.

Design/methodology/approach

An experimental approach for sample fabrication on a multiextruder 3D printer and characterization by compression testing was conducted along with numerical simulations, which were used to support the design of different auxetic configurations for the jounce bumper.

Findings

The effect of stacking different auxetic cell modules was discussed, and the findings demonstrated that a one-piece printed structure has a better performance than one composed of multiple single modules stacked on top of each other.

Research limitations/implications

The quality of the 3D printing process affected the performance of the final components and reproducibility of the results. Therefore, researchers are encouraged to further study component fabrication optimization to achieve a more reliable process.

Practical implications

This research work can help improve the manufacturing and functionality of a critical element of automotive suspension systems, such as the jounce bumper, which can efficiently reduce noise, vibration and harshness by absorbing impact energy.

Originality/value

In previous research, auxetic structures for the application of jounce bumpers have already been suggested. However, to the best of the authors’ knowledge, in this work, an AM approach was used for the first time to fabricate multimaterial auxetic structures, not only by co-printing a flexible thermoplastic polymer with a stiffer one but also by continuously extruding multilevel structures of auxetic cell modules.
Limits of three‐dimensional target detectability of logging while drilling deep‐sensing electromagnetic measurements from numerical modelling
Authors: Jahani Nazanin , Torres‐Verdín Carlos , Hou Junsheng
Published: November 2023

Subsurface energy resources are often found in three‐dimensional and non‐spatially continuous rock formations that exhibit electrical anisotropy. Deep‐sensing tri‐axial borehole electromagnetic measurements are currently being used to detect three‐dimensional fluid‐bearing subsurface formations, but borehole environmental, geometrical and instrument‐design factors, together with measurement noise, constrain their practical range of detection and spatial resolution. By understanding the interplay of the above factors on the detectability and sensitivity of borehole deep electromagnetic measurements, one can potentially quantify the uncertainty of both target spatial location (relative to the well trajectory) and electrical resistivity contrast, thereby improving the certainty of three‐dimensional well navigation in real time. We implement a finite‐volume method to numerically solve Maxwell's equations for three‐dimensional electrically anisotropic heterogeneous rock formations in the calculation of magnetic fields measured with deep‐sensing tri‐axial borehole electromagnetic instruments. The calculated magnetic fields at measurement locations are described as the per cent difference between measurements acquired in rock formations with and without conductive or resistive three‐dimensional targets. We quantify the maximum radial distance of detection from the well trajectory and the spatial sensitivity of a commercially available deep‐sensing electromagnetic instrument with respect to environmental factors and measurement acquisition parameters by assuming that the borehole electromagnetic instrument can reliably detect offset three‐dimensional targets if the corresponding per cent measurement difference exceeds the threshold for measurement noise. Results indicate that commercially available tri‐axial deep‐sensing borehole electromagnetic instruments can achieve maximum detection distances between a quarter of and a full transmitter–receiver spacing. In addition, we show that radial detection distances vary from 0.3 to 2 skin depths depending on the geological environment, that is, target conductivity contrast with respect to the embedding background, electrical anisotropy of the background formation and targets and measurement acquisition parameters, that is, frequency and transmitter–receiver spacings. The above findings are not only important for instrument design and measurement‐acquisition planning but also for the effective implementation of real‐time inversion‐based measurement interpretation procedures.
Advancing governance indicators: Four ways forward
Authors: Anheier Helmut K.
Published: November 2023

This article goes beyond the presentation, assessment and discussion of the Berggruen Governance Index by suggesting potential next steps for governance indicators and relevant data systems more generally. Specifically, it addresses four ways to advance research on governance performance. The first two, greater cross‐validation and cross‐fertilisation and a systematic assessment of the legal‐regulatory context, address the two major challenges of current research, namely the weak connection between the theoretical understanding of governance and the current stock of indicators as well as the tenuous connection between conceptually grounded indices on the one hand and the needs of policymakers to have actionable results on the other. The other two proposals, that is the development of governance operationalisations based on network structures and the notion of planetary governance, suggest transcending the current nation‐state and variable‐based frame for governance indices towards actor‐based indicators and dashboards.
Introducing the Berggruen Governance Index II: Initial results, 2000–2019
Authors: Anheier Helmut K. , Lang Markus , Knudsen Edward L.
Published: November 2023

This article presents an overview of some of the main findings from our analysis of the Berggruen Governance Index for the 2000–2019 period. It first examines overall governance performance across world regions, singles out general trends and identifies top and bottom performers. It then briefly reviews the comparative governance performance of world powers like the United States, Brazil, China, major European countries, India and Russia as well as other selected countries in the post‐Soviet space. Finally, we address more analytic questions to show the versatility of the index for hypothesis testing and theoretical purposes.
Endometrial TGFβ signaling fosters early pregnancy development by remodeling the fetomaternal interface
Authors: Parks Sydney E. , Geng Ting , Monsivais Diana
Published: November 2023

The endometrium is a unique and highly regenerative tissue with crucial roles during the reproductive lifespan of a woman. As the first site of contact between mother and embryo, the endometrium, and its critical processes of decidualization and immune cell recruitment, play a leading role in the establishment of pregnancy, embryonic development, and reproductive capacity. These integral processes are achieved by the concerted actions of steroid hormones and a myriad of growth factor signaling pathways. This review focuses on the roles of the transforming growth factor β (TGFβ) pathway in the endometrium during the earliest stages of pregnancy through the lens of immune cell regulation and function. We discuss how key ligands in the TGFβ family signal through downstream SMAD transcription factors and ultimately remodel the endometrium into a state suitable for embryo implantation and development. We also focus on the key roles of the TGFβ signaling pathway in recruiting uterine natural killer cells and their collective remodeling of the decidua and spiral arteries. By providing key details about immune cell populations and TGFβ signaling within the endometrium, it is our goal to shed light on the intricate remodeling that is required to achieve a successful pregnancy.
