A closer look at the relationship between firm-specific return variation and stock returns
Authors: Nguyen Ha , Lan Yihui , Treepongkaruna Sirimon 
Published: July 2023

PurposePrior studies use two measures of firm-specific return variation (FSRV): idiosyncratic volatility in absolute and relative terms, the latter of which is also termed stock price nonsynchronicity. Whereas most research focuses on investigating the idiosyncratic volatility puzzle, the authors carry out comparison of these two measures and further investigate which of the two constituents of nonsynchronicity explain the association between FSRV and stock returns, emphasising the importance of assessing which component drives stock returns.Design/methodology/approachThe authors use the US individual stock returns from 1925 to 2016 and define the two measures of FRSV based on the Fama and French (1993) model. Specifically, the authors decompose the relative measure into two components: (i) absolute idiosyncratic volatility and (ii) systematic volatility. The authors conduct various tests based on high-minus-low, zero-investment quintile portfolio sorts and perform the Fama–MacBeth analysis by singling out each component.FindingsThe authors find a positive return on the portfolio sorted on relative idiosyncratic volatility or on systematic volatility, but find a negative return sorted on absolute idiosyncratic volatility. The results are robust after controlling for size, BM and other risk characteristics using a double-sorting approach. The Fama–MacBeth regression results show that a positive association between the relative measure and stock returns is driven primarily by the low-systematic-volatility anomaly across firms. The findings are robust to controlling for return residual momentum, skewness, jumps and information discreteness.Originality/valueExtant research posits the idiosyncratic volatility puzzle and the low-volatility anomaly. The authors emphasize the importance of integrating these two streams of research. This study enhances the understanding of the driving force underlying the relationship between FSRV and cross-sectional stock returns.
Quantifying the drivers of residential housing demand – an interpretable machine learning approach
Authors: Cajias Marcelo , Zeitler Joseph-Alexander 
Published: July 2023

PurposeThe paper employs a unique online user-generated housing search dataset and introduces a novel measure for housing demand, namely “contacts per listing” as explained by hedonic, geographic and socioeconomic variables. Design/methodology/approachThe authors explore housing demand by employing an extensive Internet search dataset from a German housing market platform. The authors apply state-of-the-art artificial intelligence, the eXtreme Gradient Boosting, to quantify factors that lead an apartment to be in demand.FindingsThe authors compare the results to alternative parametric models and find evidence of the superiority of the nonparametric model. The authors use eXplainable artificial intelligence (XAI) techniques to show economic meanings and inferences of the results. The results suggest that hedonic, socioeconomic and spatial aspects influence search intensity. The authors further find differences in temporal dynamics and geographical variations.Originality/valueTo the best of the authors’ knowledge, it is the first study of its kind. The statistical model of housing search draws on insights from decision theory, AI and qualitative studies on housing search. The econometric approach employed is new as it considers standard regression models and an eXtreme Gradient Boosting (XGB or XGBoost) approach followed by a model-agnostic interpretation of the underlying effects.

Authors: Goumaa Rasha , Hay Amanda , El Ayouby Lamia 
Published: July 2023

Purpose Reflecting emerging concerns about Principles of Responsible Management Education’s (PRME's) reach beyond the West, the authors provide an analysis of its contribution to responsible management development in the Middle East and North Africa (MENA) region.Design/methodology/approach Drawing on 18 PRME MENA signatories' Sharing Information on Progress Reports, the authors examine levels of engagement with PRME, as well the practices used in the region to progress its six principles. The authors examine the depth of integration based on Rusinko's (2010) typology and its success in addressing local responsible management challenges.Findings The analysis revealed modest levels of engagement with PRME in MENA. Consistent with other regions, for those actively participating, the authors identified a wide variation in PRME responses. First, the authors found wide variation in the interpretation of the six principles. Second, the authors found a diversity of practices, especially the extent to which efforts were linked to progressing local management challenges. Third, the authors also found variability relating to the depth of PRME's integration into the curricular of MENA signatories with, most displaying Ruskino's (2010) narrower approaches.Originality/value The authors address calls to understand the contribution of PRME beyond Western contexts and offer suggestions for how PRME can be strengthened to facilitate responsible management development in MENA.
Skill rather than beak kinematics affects seed handling performance in a granivorous songbird
Authors: Andries Tim , Müller Wendt , Van Wassenbergh Sam 
Published: July 2023

Abstract

In granivorous songbirds, feeding is a complex process as seeds need to be dehusked before they can be consumed, making the feeding act a biomechanically challenging endeavour. However, most previous research has focused on how beak morphology affects feeding performance, while the influences of beak kinematics remain largely unknown.

In this study, we hence investigated at the individual level how feeding performance (i.e. seed processing time and success rate) relates to both beak kinematics (i.e. beak tip speed, acceleration, frequency) and skill (i.e. seed handling tactics and cracking techniques) in the Canary Serinus canaria. To do so, high‐speed videos during feeding were recorded and subjected to automated tracking of beak tip movements.

Better skills, that is accurate positioning of the seed for being split in half, reduced total seed handling time compared to more random positioning and crushing the husk into multiple, scattering fragments. Surprisingly, individual variation in beak speed, acceleration or frequency generally did not relate to differences in performance.

Thus, our data suggest that seed positioning precision, and hence the control of coordinated beak and tongue movement, is critical to minimize feeding durations in songbirds. Further studies are needed to explore whether this develops via a positive feedback between behaviour, learning and increased efficiency or if it relates to intrinsic differences.

Deliberate disproportionate policy outcomes and regulating deforestation in Queensland, Australia
Authors: Boer Henry 
Published: July 2023

AbstractThis paper analyses the strategic interests that inform deforestation policies in Australia, and the variance in policy selections over time. A theory of deliberate policy disproportionality is used to analyse 20 years of regulatory reform in Queensland, focusing on the Vegetation Management Act (VMA) 1999. Application of the framework to this case suggests that political executives were prone to deliberately adopt (dis)proportionate policies as a strategic response to either manage or capitalise on stakeholder support or opposition to any proposed legislative change. The high variance in (dis)proportionate deforestation policies is attributed to how political executives respond to claims made by competing constituencies regarding the costs versus benefits of successive reforms. During key reform phases, policy under‐reaction was the norm, and political executives intentionally limited the scope and effectiveness of the VMA 1999 due to perceived impacts on the agricultural sector. Political executives were highly responsive to the emotional investment of rural constituents and averse to introducing policies that required difficult trade‐offs. Elections offered strategic opportunities for delivering more proportionate policies that balanced public environmental benefits with economic impacts, as evidenced by a conditional deforestation ban introduced between 2004 and 2012 and reinstated in 2018.Points for practitioners
Variance in Queensland's deforestation policy over time can be attributed to the intentional decisions by political executives to limit or expand the scope of regulations as a strategic response to stakeholder expectations.
Political executives were responsive to the costs versus environmental impacts/benefits of any deforestation reforms, but prone to policy under‐reaction when the priority was managing the emotive reactions from rural constituencies.
More proportionate regulations, such as the partial deforestation ban of 2004, aimed to balance environmental benefits with compensation for landholders but were only implemented when electorally beneficial.
Stakeholders have a significant influence on disproportionate deforestation policy design and governments will need to manage competing claims to deliver more durable policy outcomes.
A Cognitive Method for Comparing and Elaborating on Technology Frames
Authors: Ghobadi Shahla , Mathiassen Lars 
Published: July 2023

AbstractFrom employees’ varied interpretations of software efficacy to consumers’ diverse beliefs about data privacy, technology frames refer to cognitive interpretations, assumptions and expectations that people use to comprehend the essence of information technology within a particular context. These frames differ across groups with different values, interests, experiences and expertise, having critical implications for researchers, managers and organizations. Despite theoretical enthusiasm to understand technology frames, limited methodological insights exist on how to systematically explore and compare technology frames. This gap impedes researchers from exploring novel questions related to technology frames, their variations and how they can be managed effectively. This paper proposes a cognitive method for comparing and elaborating on technology frames. Building on causal mapping and empirical studies, the method formulates steps to plan, elicit, compare and elaborate on the relationships that underlie framing differences. The method offers detailed recommendations and templates for effectively organizing and communicating diverse manifestations of framing differences and their implications. The paper concludes by highlighting the method's practical implications and encouraging research to advance extant knowledge of technology frames in the rapidly changing digital world.
Suspected myocardial infarction in the emergency department: An evaluation of clinical thresholds for the Beckman Coulter Access hsTnI high‐sensitivity cardiac troponin I assay

Published: July 2023

AbstractObjectiveThe primary objective was to determine rapid rule‐out (RRO) criteria for the outcome of myocardial infarction (MI) using the Beckman Coulter Access high‐sensitivity cardiac troponin I (hs‐cTnI) assay. Secondary objectives were to explore cut‐points for rapid rule‐in (RRI) and amount of change at 3‐h (3‐h delta) indicative of MI.MethodsA retrospective study included ED patients with suspected MI between June and September 2019. hs‐cTnI levels were performed at baseline and after 3 h. The performance benchmark for RRO criteria was a negative predictive value (NPV) for MI with a lower 95% confidence limit >99%, and for RRI and 3‐h delta cut‐points was a positive predictive value (PPV) for MI >70%. Delta calculation required rising hs‐cTnI levels, with at least one above the 99th percentile of the upper reference limit. Analyses utilised receiver operating characteristic (ROC) curves and contingency tables.ResultsBaseline hs‐cTnI levels from 935 patients were available for RRO analyses. Of tested criteria, baseline hs‐cTnI <6 ng/L (females) or <11 ng/L (males) plus symptom onset >2 h met the performance benchmark (NPV: 100% [95% confidence interval 99–100]). hs‐cTnI levels were available for RRI and 3‐h delta analyses from 935 and 52 patients, respectively. A 3‐h delta cut‐point >35 ng/L met the performance benchmark (PPV: 81% [95% confidence interval 58–95]) but no RRI cut‐point did so.ConclusionsFor the Beckman Coulter Access hs‐cTnI assay, RRO criteria of baseline hs‐cTnI <6 ng/L (females) or <11 ng/L (males) plus symptom onset >2 h met our performance benchmark. A 3‐h delta cut‐point >35 ng/L met the performance benchmark, but poor precision means further adequately powered research is required.

Published: July 2023

ObjectivesPercutaneous electrical nerve field stimulation (PENFS) has documented efficacy for irritable bowel syndrome (IBS) via plausible vagal neuromodulation effects. The vagus nerve may affect gut microbiome composition via brain–gut–microbiome signaling. We aimed to investigate gut microbiome alterations by PENFS therapy in adolescent IBS patients.MethodsA prospective study of females with IBS aged 11–18 years receiving PENFS therapy for 4 weeks with pre‐ and post‐intervention stool sampling was conducted. Outcome surveys completed pre‐therapy, weekly, and post‐therapy included IBS‐Severity Scoring System (IBS‐SSS), Visceral Sensitivity Index (VSI), Functional Disability Inventory (FDI), and the global symptom response scale (SRS). Bacterial DNA was extracted from stool samples followed by 16S rRNA amplification and sequencing. QIIME 2 (version 2022.2) was used for analyses of α and β diversity and differential abundance by group.ResultsTwenty females aged 15.6 ± 1.62 years were included. IBS‐SSS, VSI, and FDI scores decreased significantly after PENFS therapy (P < 0.0001, P = 0.0003, P = 0.0004, respectively). No intra‐ or interindividual microbiome changes were noted pre‐ versus post‐therapy or between responders and non‐responders. When response was defined by 50‐point IBS‐SSS score reduction, α diversity was higher in responders compared with non‐responders at week 4 (P = 0.033). There was higher abundance of Blautia in excellent responders versus non‐responders.ConclusionsThere were no substantial microbial diversity alterations with PENFS. Subjects with excellent therapeutic response showed an enrichment of relative abundance of Blautia, which may indicate that patients with specific microbial signature have a more favorable response to PENFS.
Understanding the role of GRE3 in the erythritol biosynthesis pathway in Saccharomyces uvarum and its implication in osmoregulation and redox homeostasis
Authors: Albillos‐Arenal Sonia , Minebois Romain , Querol Amparo , Barrio Eladio 
Published: July 2023

AbstractErythritol is produced in yeasts via the reduction of erythrose into erythritol by erythrose reductases (ERs). However, the genes codifying for the ERs involved in this reaction have not been described in any Saccharomyces species yet. In our laboratory, we recently showed that, during alcoholic fermentation, erythritol is differentially produced by Saccharomyces cerevisiae and S. uvarum species, the latter being the largest producer. In this study, by using BLAST analysis and phylogenetic approaches the genes GRE3, GCY1, YPR1, ARA1 and YJR096W were identified as putative ERs in Saccharomyces cerevisiae Then, these genes were knocked out in our S. uvarum strain (BMV58) with higher erythritol biosynthesis compared to control S. cerevisiae wine strain, to evaluate their impact on erythritol synthesis and global metabolism. Among the mutants, the single deletion of GRE3 markedly impacts erythritol production, although ΔYPR1ΔGCY1ΔGRE3 was the combination that most decreased erythritol synthesis. Consistent with the increased production of fermentative by‐products involved in redox balance in the Saccharomyces uvarum strain BMV58, erythritol synthesis increases at higher sugar concentrations, hinting it might be a response to osmotic stress. However, the expression of GRE3 in the S. uvarum strain was found to peak just before the start of the stationary phase, being consistent with the observation that erythritol increases at the start of the stationary phase, when there is low sugar in the medium and nitrogen sources are depleted. This suggests that GRE3 plays its primary function to help the yeast cells to maintain the redox balance during the last phases of fermentation.
Ineficácia das formigas na proteção de duas plantas mirmecófilas simpátricas contra besouros endofíticos

Published: July 2023

ResumoAs plantas com nectários extraflorais (NEFs) atraem formigas, que podem protegê‐las contra a herbivoria e aumentar a produção de frutos. Em alguns casos, porém, as formigas são ineficazes contra os herbívoros. Tais eventos ocorrem, por exemplo, quando os herbívoros apresentam adaptações para evitar a predação pelas formigas. Assim, os resultados dessas interações dependem de fatores como a identidade da formiga, fenologia da planta e características do herbívoro. Aqui, investigamos o impacto de besouros florívoros endofíticos sobre o sucesso reprodutivo de suas plantas hospedeiras, duas espécies simpátricas de Banisteriopsis (Malpighiaceae), dependendo da ação das formigas visitantes de nectários extraflorais. Manipulamos experimentalmente a presença de formigas e herbívoros nas espécies B. malifolia e B. laevifolia durante seu período reprodutivo para testar a eficácia do mutualismo formigas‐NEFs na produção do conjunto de frutos da planta. Realizamos tratamentos onde três inflorescências similares foram selecionadas para serem (I) ramo de controle, sem manipulações, (II) ramo livre de besouros, isolado com cobertura de tecido e (III) ramo livre de formigas, isolado na base com cera atóxica. Formulamos a hipótese de que os herbívoros endofíticos têm um impacto negativo sobre o sucesso reprodutivo das plantas porque escapam da ação das formigas (defesas bióticas). Como resultado, observamos (i) que os besouros florívoros Anthonomus têm um impacto negativo no sucesso reprodutivo de Banisteriopsis; (ii) as formigas falham na proteção das plantas contra os besouros endofíticos florívoros; e (iii) a maioria dos resultados foram específicos da espécie. Nossos resultados indicam que estes sistemas apresentam resultados condicionais que dependem dos fatores intrínsecos de cada espécie de planta.
Decolonizing anthropology
Authors: Bolles A. Lynn 
Published: July 2023

AbstractThirty‐two years after the publication of Faye V. Harrison's edited volume, Decolonizing Anthropology: Moving Further toward an Anthropology of Liberation, I take stock of the book's origins and its impact on the discipline. Despite intellectual barriers and postmodernist critiques, Decolonizing Anthropology has influenced a generation of anthropologists who carry forward the book's original spirit. Focusing on the third edition, I show that Decolonizing has both reflected and incited changes in the discipline. Finally, I turn to some recent work in which scholars continue to push the boundaries of what decolonizing anthropology can mean. Throughout, I emphasize the importance of decolonization as a practice in anthropology and highlight the ongoing struggles and successes of scholars working in this tradition.
Association between levothyroxine treatment for maternal subclinical hypothyroidism with negative TPOAb and early child neurodevelopment: A prospective real‐world clinical trial

Published: July 2023

AbstractIntroductionSubclinical hypothyroidism (SCH) during pregnancy is reported to have detrimental impact on pregnancy and child development. However, its treatment indications require further investigation in different thyroid peroxidase antibody (TPOAb) status.Material and methodsThis was a secondary analysis of a Chinese prospective cohort in a real‐world setting. Pregnant women with gestational SCH were enrolled at the first antenatal visit and grouped by TPOAb positivity. Child neurodevelopment was assessed by the Gesell development diagnosis scale (GDDS) at one, three, six, 12, and 24 months of age. Subgroup analyses and sensitivity analyses were also conducted. Clinical trial registration: ClinicalTrials.gov NCT01744743.ResultsFrom January 2012 to December 2013, a total of 171 participants were enrolled, including 116 of SCH with TPOAb negative (SCH‐TPOAb [−]) and 55 of SCH with TPOAb positive (SCH‐TPOAb [+]). Compared to women in the SCH‐TPOAb (+) group, those in the SCH‐TPOAb (−) group had lower thyroid‐stimulating hormone (TSH) levels at enrollment and 12–16+6 gestational weeks, and unexpectedly higher TSH levels at 30–34+6 gestational weeks and delivery, with a correspondingly lower levothyroxine dosage throughout pregnancy (all p < 0.05). Offspring in the SCH‐TPOAb (−) group displayed lower GDDS scores at one year old than did their counterparts (adjusted p < 0.05), which was possibly related to the worse thyroid function control of maternal SCH‐TPOAb (−). No statistically significant difference was found in the GDDS assessments of children at one, three, six, and 24 months of age. These results were also confirmed in subgroup analyses stratified by maternal thyroid characteristics at enrollment, namely TSH levels, free levothyroxine (T4) levels, and anti‐thyroglobulin antibody (TgAb) status, as well as in sensitivity analyses excluding participants with no levothyroxine treatment at enrollment.ConclusionsIn the current clinical practice, infants born to mothers with SCH‐TPOAb (−) displayed slightly lower neurodevelopmental scores at one year old than did those born to mothers with SCH‐TPOAb (+) but this difference was not seen at two years.
Where next for managed retreat: Bringing in history, community and under‐researched places
Authors: Taylor Aiken Gerald , Mabon Leslie 
Published: July 2023

AbstractManaged retreat—the purposive and coordinated movement of people away from climate risks—has risen in importance, discussion and urgency in recent years. As climate threats increase in size and scope, both scholarly and policy responses are likely to take increasing interest in this deeply geographic phenomenon. This is an important juncture to take stock, and reflect on what Geography can offer both academic and policy responses to managed retreat. While managed retreat has developed a critical and useful set of tools and ideas for dealing with profound climate adaptation measures, there remain omissions. Here we point to the historical perspective, participative community‐based approaches, and diversifying from over‐researched examples that can dominate this (sub)field as aspects that can all be strengthened going forward. To end, we offer three recommendations for further thought on managed retreat.
