Stock markets volatility during crises periods: a bibliometric analysis
Authors: Goyal Priyanka , Soni Pooja 
Published: April 2024

Purpose
Given the dearth of thorough summaries in the literature, this systematic review and bibliometric analysis attempt to take a meticulous approach meant to present knowledge on the constantly developing subject of stock market volatility during crises. In outline, this study aims to map the extant literature available on stock market volatility during crisis periods.

Design/methodology/approach
The present study reviews 1,283 journal articles from the Scopus database published between 1994 and 2022, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 flow diagram. Bibliometric analysis through software like R studio and VOSviewer has been performed, that is, annual publication trend analysis, journal analysis, citation analysis, author influence analysis, analysis of affiliations, analysis of countries and regions, keyword analysis, thematic mapping, co-occurrence analysis, bibliographic coupling, co-citation analysis, Bradford’s law and Lotka’s law, to map the existing literature and identify the gaps.

Findings
The literature on the effects of crises on volatility in financial markets has grown in recent years. It was discovered that volatility intensified during crises. This increased volatility can be linked to COVID-19 and the global financial crisis of 2008, as both had massive effects on the world economy. Moreover, we identify specific patterns and factors contributing to increased volatility, providing valuable insights for further research and decision-making.

Research limitations/implications
The present study is confined to the areas of economics, econometrics and finance, business, management and accounting and social sciences. Future studies could be conducted considering a broader perspective.

Originality/value
Most of the available literature has focused on the impact of some particular crises on the volatility of financial markets. The present study is not limited to some specific crises, and the suggested research directions will serve as a guide for future research.

Published: April 2024

AbstractThe in situ acoustic measurement of seafloor sediment is an important technical means to obtain the acoustic parameters of seafloor. The time‐of‐flight method is commonly used to calculate the sound speed in seafloor sediment. Accurate identification of signal feature points is essential for determining travel time or travel time difference of acoustic signals. However, the precise identification of feature points, such as the take‐off point of the first wave of a sound wave signal, is challenging. The conventional manual identification method is inefficient and prone to errors. The development of a feature point auto‐identification method is imperative for accurately calculating the travel time of acoustic signals. In this study, we employed the cross‐correlation method, the level threshold method and the short window‐long window energy ratio method to extract the acoustic travel time differences and calculate the sound speeds in seawater and in seafloor sediment. We then analysed the effectiveness of these calculated results. The sound speeds in seawater obtained through the aforementioned methods were compared with the sound speeds measured using a sound velocity profiler. The comparison revealed that these processing methods exhibit a high level of accuracy. The sound speed results in sediments show that the programme‐based auto‐identification methods significantly reduce the standard deviation compared to the manual identification method. This study successfully assessed the processing accuracy of different methods and expanded the processing methods for in situ acoustic signals of seafloor sediments.
Silent suasions: interpersonal mediation in Thai meditation
Authors: Cassaniti Julia 
Published: April 2024

AbstractDiscourse is the typical modus operandi for persuasive practices, but silence also has an important role to play in many religious contexts. In this essay, I examine how silence works as a mechanism of persuasion in Thailand, where Buddhist logics of meditation permeate social life. Through a close analysis of a meditative retreat at Wat Pradhatu Sri Chom Thong Voravihan in Northern Thailand, I suggest three ways that silence comes to create its persuasive effects: it works in contrastive relation to speech; it is symbolic of moral personhood; and it points to interpersonal corporeal attunement. Attention to the corporeal aspect of silence is especially significant, I argue, because it is through the body that the practice in Thailand acts to alter intersubjective space. Such an approach to silence as disciplinary practice, rather than attention just to its supposed effects, allows us to see how religious forms of silent persuasion can be seen as a particularly powerful force for personal and political change.

Published: April 2024

AbstractObjectiveTo examine the uptake of postnatal contraception (PNC) and experiences of PNC care across a geographical region of England.DesignCross‐sectional online survey.SettingThe North East and North Cumbria Integrated Care System (ICS).PopulationWomen who had completed a pregnancy in the previous 3 years.MethodsThe uptake of PNC by accessed method(s) and the availability of preferred method(s) is described, and adjusted odds ratios are reported for group differences in uptake by characteristics of interest.Main outcome measuresUptake of medically prescribed/administered contraception and uptake of long‐acting reversible contraception (LARC) during the postnatal period, and access to preferred PNC methods.ResultsAlthough almost half of respondents (47.1%; n = 1178) reinitiated some form of sexual activity during the postnatal period, only 38.7% (n = 969) of respondents accessed a medically prescribed/administered contraceptive method postnatally, and only 15.5% (n = 389) of respondents accessed a LARC. It is a matter of concern that 18.8% (n = 451) of respondents indicated that they were unable to access their preferred PNC. In multivariate analysis, younger age, lower household income, higher multiparity, operative delivery, unplanned pregnancy and not breastfeeding were significant predictors of higher PNC uptake.ConclusionsThe uptake of PNC in this cohort was low, with almost a fifth of women unable to access their preferred method. However, there was some evidence that women belonging to groups perceived to be at risk of rapid repeat pregnancy were more likely to access reliable PNC methods.
Can bioplastics always offer a truly sustainable alternative to fossil‐based plastics?
Authors: Serrano‐Aguirre Lara , Prieto M. Auxiliadora 
Published: April 2024

AbstractBioplastics, comprised of bio‐based and/or biodegradable polymers, have the potential to play a crucial role in the transition towards a sustainable circular economy. The use of biodegradable polymers not only leads to reduced greenhouse gas emissions but also might address the problem of plastic waste persisting in the environment, especially when removal is challenging. Nevertheless, biodegradable plastics should not be considered as substitutes for proper waste management practices, given that their biodegradability strongly depends on environmental conditions. Among the challenges hindering the sustainable implementation of bioplastics in the market, the development of effective downstream recycling routes is imperative, given the increasing production volumes of these materials. Here, we discuss about the most advisable end‐of‐life scenarios for bioplastics. Various recycling strategies, including mechanical, chemical or biological (both enzymatic and microbial) approaches, should be considered. Employing enzymes as biocatalysts emerges as a more selective and environmentally friendly alternative to chemical recycling, allowing the production of new bioplastics and added value and high‐quality products. Other pending concerns for industrial implementation of bioplastics include misinformation among end users, the lack of a standardised bioplastic labelling, unclear life cycle assessment guidelines and the need for higher financial investments. Although further research and development efforts are essential to foster the sustainable and widespread application of bioplastics, significant strides have already been made in this direction.

AbstractThe origin of flight and laryngeal echolocation in bats is likely to have been accompanied by evolutionary changes in other aspects of their sensory biology. Of all sensory modalities in bats, olfaction is perhaps the least well understood. Olfactory receptors (ORs) function in recognizing odour molecules, with crucial roles in evaluating food, as well as in processing social information. Here we compare OR repertoire sizes across taxa and apply a new pipeline that integrates comparative genome data with protein structure modelling and then we employ molecular docking techniques with small molecules to analyse OR functionality based on binding energies. Our results suggest a sharp contraction in odorant recognition of the functional OR repertoire during the origin of bats, consistent with a reduced dependence on olfaction. We also compared bat lineages with contrasting different ecological characteristics and found evidence of differences in OR gene expansion and contraction, and in the composition of ORs with different tuning breadths. The strongest binding energies of ORs in non‐echolocating fruit‐eating bats were seen to correspond to ester odorants, although we did not detect a quantitative advantage of functional OR repertoires in these bats compared with echolocating insectivorous species. Overall, our findings based on molecular modelling and computational docking suggest that bats have undergone olfactory evolution linked to dietary adaptation. Our results from extant and ancestral bats help to lay the groundwork for targeted experimental functional tests in the future.
Malignant hyperthermia safety – A nationwide survey of publicly funded Swedish healthcare

Published: April 2024

AbstractBackgroundMalignant hyperthermia (MH) is a rare pharmacogenetic disorder that can lead to a life‐threatening reaction during general anaesthesia with triggering agents. Prompt life‐saving treatment includes the immediate administration of the antidote dantrolene. This study investigated Swedish healthcare providers' awareness and adherence to guidelines and recommendations with respect to MH and whether adherence to safe MH‐praxis varies with hospital care‐complexity level and private versus public management form.MethodAgreements and procurement specifications between all 21 Swedish County Councils and privately run surgical care providers were reviewed alongside with questionnaire‐aided collection of information from 62 publicly funded health care providers (both privately and publicly run).ResultsNo procurement requirement specification or contract contained requirements on anaesthesia or aspects of MH. All publicly run hospitals stocked dantrolene and 28 out of 52 (54%) stocked the recommended amount. Seven out of nine (78%) of the privately run institutions stocked dantrolene, and one stocked the recommended amount. Publicly run hospitals adhered to recommendations to a greater extent than privately run institutions, both with respect to stocking of dantrolene (p = .02) and to stocking the recommended amount (p = .03).ConclusionsContracts between Swedish county councils and private surgical care subcontractors rarely outline expectations of standards for the safe practice of anaesthesia such as preparedness to handle a life‐threatening MH reaction. Among Swedish publicly funded anaesthesia providers there is room for improvement in adherence to the EMHG guideline on dantrolene availability. Publicly run hospitals seem to have better compliance with these recommendations than privately run institutions. Raising awareness about current guidelines is important to improve safety for known and unknown MH‐susceptible individuals.
Methylation entropy landscape of Chinese long‐lived individuals reveals lower epigenetic noise related to human healthy aging

AbstractThe transition from ordered to noisy is a significant epigenetic signature of aging and age‐related disease. As a paradigm of healthy human aging and longevity, long‐lived individuals (LLI, >90 years old) may possess characteristic strategies in coping with the disordered epigenetic regulation. In this study, we constructed high‐resolution blood epigenetic noise landscapes for this cohort by a methylation entropy (ME) method using whole genome bisulfite sequencing (WGBS). Although a universal increase in global ME occurred with chronological age in general control samples, this trend was suppressed in LLIs. Importantly, we identified 38,923 genomic regions with LLI‐specific lower ME (LLI‐specific lower entropy regions, for short, LLI‐specific LERs). These regions were overrepresented in promoters, which likely function in transcriptional noise suppression. Genes associated with LLI‐specific LERs have a considerable impact on SNP‐based heritability of some aging‐related disorders (e.g., asthma and stroke). Furthermore, neutrophil was identified as the primary cell type sustaining LLI‐specific LERs. Our results highlight the stability of epigenetic order in promoters of genes involved with aging and age‐related disorders within LLI epigenomes. This unique epigenetic feature reveals a previously unknown role of epigenetic order maintenance in specific genomic regions of LLIs, which helps open a new avenue on the epigenetic regulation mechanism in human healthy aging and longevity.
Political accountability under moral hazard
Authors: Acharya Avidit , Lipnowski Elliot , Ramos João 
Published: April 2024

AbstractViewing the relationship between politicians and voters as a principal–agent interaction afflicted by moral hazard, we examine how political careers are shaped by the incentives that voters provide incumbents to work in the public interest. When moral hazard binds, the optimal way for voters to hold politicians accountable is to provide re‐election incentives that evolve dynamically over their careers in office. Under these incentives, first‐term politicians are among the most electorally vulnerable and the hardest‐working; politician effort rises with electoral vulnerability; electoral security increases following good performance and decreases following bad performance; and both effort and electoral vulnerability tend to decline with tenure. In extensions, we study limited voter commitment, voluntary retirement from politics, and adverse selection.

AbstractIntroductionThe debate about observing total versus free serum valproate levels for therapeutic drug monitoring (TDM) has been unresolved for decades. This study was planned to assess the agreement between the total versus free valproate levels and the advantage of one method over the other in TDM.MethodsThe present cross‐sectional study was done on 93 patients with bipolar disorder. The intraclass correlation coefficient, Bland Altman analysis, and Lin's concordance analysis were done to assess the agreement between the total and free valproate concentrations. Linear and polynomial models were constructed to evaluate the relation between the two measurements. Receiver operating characteristics analysis was done to compare the accuracy for differentiating remission from non‐remission on Young's mania rating scale (YMRS).ResultsThe intraclass correlation coefficient and Lin's concordance correlation coefficient were 0.491 (p = .002) and 0.055 (95% CI:0.037, 0.073), respectively. Bland Altman's analysis showed proportional bias. A polynomial model of second order was found to be the best fit for the prediction of free valproate from the data for total valproate, and 81.4% of the variability in free valproate could be explained when adjusted for albumin levels. The area under the curve for total valproate was 0.60 when compared to free valproate 0.56 for differentiating between remission and non‐remission, but the comparison between the two ROC analyses was not statistically significant.ConclusionFree valproate does not provide any added advantage over the total valproate levels; hence, total valproate levels may continue to be used as the marker for drug monitoring.

ObjectiveTo identify the size and distribution of the horse population in the Northern Rivers Region of NSW, including changes from 2007 to 2021, to better understand populations at risk of Hendra virus transmission.MethodsCensus data from the 2007 Equine Influenza (EI) outbreak were compared with data collected annually by New South Wales Local Land Services (LLS) (2011–2021), and with field observations via road line transects (2021).ResultsThe horse populations reported to LLS in 2011 (3000 horses; 0.77 horses/km2) was 145% larger than that reported during the EI outbreak in 2007 (1225 horses; 0.32 horses/km2). This was inconsistent with the 6% increase in horses recorded from 2011 to 2020 within the longitudinal LLS dataset. Linear modelling suggested the true horse population of this region in 2007 was at least double that reported at the time. Distance sampling in 2021 estimated the region's population at 10,185 horses (3.89 per km2; 95% CI = 4854–21,372). Field sampling and modelling identified higher horse densities in rural cropland, with the percentage of conservation land, modified grazing, and rural residential land identified as the best predictors of horse densities.ConclusionsData from the 2007 EI outbreak no longer correlates to the current horse population in size or distribution and was likely not a true representation at the time. Current LLS data also likely underestimates horse populations. Ongoing efforts to further quantify and map horse populations in Australia are important for estimating and managing the risk of equine zoonoses.

High‐definition turns timing‐dependent: Different behavioural consequences during and following cathodal high‐definition transcranial direct current stimulation (HD tDCS) in a magnitude classification task

Published: April 2024

AbstractNeuromodulation with transcranial direct current stimulation (tDCS) can transiently alter neural activity, but its spatial precision is low. High‐definition (HD) tDCS was introduced to increase spatial precision by placing additional electrodes over the scalp. Initial evaluations of HD tDCS indicated polarity‐specific neurophysiological effects—similar to conventional tDCS albeit with greater spatial precision. Here, we compared the effects of cathodal tDCS or HD tDCS in a 4 × 1 configuration over prefrontal cortex (PFC) regions on behavioural outcomes in a magnitude classification task. We report results on overall performance, on the numerical distance effect as a measure of numerical processing, and on the spatial‐numerical associations of response codes (SNARC) effect, which was previously affected by prefrontal tDCS. Healthy volunteers (n = 68) received sham or cathodal HD tDCS at 1 mA over the left dorsolateral prefrontal cortex (DLPFC) or the left inferior frontal gyrus (IFG). Results were compared to an identical protocol with conventional cathodal tDCS to the left PFC versus sham (n = 64). Mixed effects models showed performance gains relative to sham tDCS in all conditions after tDCS (i.e. ‘offline’), whereas montages over PFC and DLPFC already showed performance gains during tDCS (i.e. ‘online’). In contrast to conventional tDCS, HD tDCS did not reduce the SNARC effect. Neither condition affected numerical processing, as expected. The results suggest that HD tDCS with cathodal polarity might require further adjustments (i.e. regarding tDCS intensity) for effective modulations of cognitive‐behavioural performance, which could be achieved by individualised current density in electric field modelling.
