Investor behavior in crisis: a comparative study of fear-driven downtrends and confidence-led recoveries
Authors: García-Monleón Fernando , González-Rodrigo Elena , Bordonado-Bermejo María-Julia 
Published: October 2024

PurposeThe purpose of this research is to investigate the differences between financial crises of fear and confidence and the differential behavior between downtrends and recovery.Design/methodology/approachFive national stock markets have been analyzed – the USA (SP500), China (Hang Seng), Spain (IBEX 35), Japan (Nikkei) and Germany (DAX) – through the evolution of three world economic crises: the mortgage bubble crisis of 2007 in the first place, with special attention to the bankruptcy of Lehman Brothers, which will be treated as an independent crisis process, and the crisis caused by COVID-19. The behavioral finance theory, with the support of the complexity theory in the field of risk management, will establish the different behavioral biases that explain the differences between the two types of crises, fear and confidence, when confronted with risk.FindingsEconomic crises resulting from a shocking event, addressed as crises of fear in this research, such as Lehman Brothers or COVID-19, are fast-moving; all the economies analyzed show a common pattern of evolution. The difference is found in the recovery periods in which the previous parallelism does not continue. Crisis events that arise from a social context, addressed as crises of trust in this research, follow similar patterns in their evolution; nonetheless, the start date presents higher variations than those originated by a shock. These crises also lack parallelism between fall and recovery.Practical implicationsUnderstanding crisis process patterns may help to prevent them and alleviate their effects when they occur.Originality/valueUnderstanding crisis process patterns may help to prevent them and alleviate their effects when they occur. This constitutes an original field of research.
Towards a responsible gaming ecosystem: a call to action
Authors: Yap Sheau Fen (Crystal) 
Published: October 2024

Purpose
Drawing from transformative service research (TSR) and service ecosystem perspectives, the author seeks to provide multi-level insights into gaming service systems and call to action how this knowledge can contribute to cultivating socially responsible gaming by addressing the following research questions: What insights from service ecosystem and TSR literature can help optimise value co-creation and cultivate socially responsible practices in digital gaming services? What future research directions could advance the understanding of digital gaming services and their potential to develop a responsible gaming ecosystem that balances social well-being with commercial success?

Design/methodology/approach
Adopting a conceptual approach of theory synthesis and adaptation, the author discusses four overarching themes alongside key research gaps and directions crucial for understanding the dynamics of gaming ecosystem.

Findings
The central themes – “Exploring individuals as game service consumers”, “Gaming service exchange dynamics among meso-level stakeholders”, “A macro lens to gaming service ecosystem” and “The complexities of multi-actor dynamics and interdependencies” – shed light on how responsible services can be fostered.

Research limitations/implications
Given the absence of a well-defined scope for understanding responsible gaming, future research should develop a typology to capture its multifaceted aspects. Expanding beyond micro-level analysis, conducting consultation interviews with industry practitioners and policymakers can contribute insights into promoting responsible gaming services.

Social implications
The author offers insights for the game players, designers and developers, service providers and policymakers to promote a healthy gaming culture.

Originality/value
Through this research, the author advances the understanding of gaming as a service by illuminating value co-creation and co-destruction within an interconnected gaming service ecosystem through the lens of TSR. Such understanding empowers businesses to prioritise consumer welfare in their decision-making and practices.

Published: October 2024

PurposeThis paper analyses the efficiency and productivity of Brazilian football clubs in the post-world cup 2014 period (2014–2022) using a network dynamic DEA-Malmquist model.Design/methodology/approachFinancial and sporting efficiency and productivity in Brazilian football clubs.FindingsThe financial division’s average efficiency is higher than that of the sporting division and overall efficiency from 2014 to 2022. Fourteen clubs exhibited increased productivity during this period. Regression models revealed a statistically significant positive relationship between the debt ratio and DEA dependent variable models at a 1% significance level and a significant negative relationship with the three Malmquist dependent variable models. Additionally, the models identified a statistically significant relationship with the “Covid” (2020 years) variable across all models.Practical implicationsOur findings suggest that increased expenditures can lead to higher liabilities, reducing the ability to afford high-quality players and thus diminishing overall club value. Additionally, the inefficiencies observed among some of the largest football clubs reveal room for improvement in both financial and sportive aspects.Originality/valueThis is the first study to investigate efficiency and productivity in two dimensions for Brazilian football clubs, incorporating an analysis of productivity over an extended period and examining the impact of debt and other determinants on club performance.
Crossing boundaries: developing preservice teachers' professional identity through hybrid school–university partnerships
Authors: Buelow Stephanie 
Published: October 2024

PurposeSchool–university partnerships are the core of effective teacher preparation programs, and central to this model are the classroom teachers who mentor preservice teachers into the profession. This article describes an innovative collaboration that transcends institutional boundaries, operating in a hybrid space, aimed at supporting preservice teachers' development as educators, expanding their professional networks and fostering their sense of belonging and professional identity within a broader community of teacher leaders.Design/methodology/approachThis article describes a hybrid partnership model that provides preservice teachers with innovative mentoring experiences. Research on hybrid partnership models and boundary-spanning frames the discussion. The article provides a brief overview of two iterations of a collaboration between elementary preservice teachers and a cohort of teacher leaders in a fellowship program. The paper concludes by discussing lessons learned and directions for future research on the topic.FindingsPreservice teachers benefit from opportunities to engage with a variety of mentors throughout their program. While the classroom teacher serving as a mentor is central to teacher preparation, there is a space for hybrid partnership models that provide preservice teachers additional mentors to support their development and connections to a professional learning community of teacher leaders. Through innovative hybrid collaborations, preservice teachers engage with diverse mentors, expanding their professional networks and preparing them to navigate the complexities of the educational landscape with a sense of belonging and identity.Originality/valueThis article contributes to the literature on hybrid partnership models, aimed at empowering preservice teachers by integrating them into a professional community of teacher leaders, fostering their sense of belonging, identity and preparedness to navigate the complexities of the profession.

Published: October 2024

AbstractPrevious reports have demonstrated that alcohol consumption significantly reduces the abundance of Lactobacillus in the gut. In this study, we selected five species of the genus Lactobacillus, commonly found in fermented foods, and acknowledged them as safe, edible, and effective in preventing or treating certain diseases, to evaluate their effects on alcoholic liver disease (ALD). By comparing the liver damage indices in each group, we found that the type strain of Lactobacillus helveticus (LH, ATCC 15009) had the most marked alleviating effect on ALD‐induced liver injury. Furthermore, experiments combining microbiomics and metabolomics were conducted to explore the mechanisms underlying the hepatoprotective effects of LH. Finally, we discovered that LH mitigated ethanol‐induced liver steatosis and inflammation in ALD mice by altering the structure and function of the gut microbiome, increasing intestinal levels of short‐chain fatty acids (SCFAs), and enhancing gut barrier integrity. These findings suggest a potential strategy for the clinical management of patients with ALD.
A keep‐it‐simple embolisation approach to treat pelvic congestion syndrome without compromising clinical effectiveness
Authors: Liang Eisen , Wong Wai Yan Timothy , Parvez Razeen , Chan Michael , Brown Bevan 
Published: October 2024

AbstractIntroductionThere are two approaches to treating pelvic congestion syndrome (PCS): (i) the keep‐it‐simple (KIS) approach, which involves embolising only the refluxing vein(s), typically the left ovarian vein (LOV) unless the right ovarian vein (ROV) or left/right internal iliac vein (IIV) tributaries are also refluxing; and (ii) the extensive (EXT) approach, which empirically embolises almost all of the LOV, ROV, and left and right IIV tributaries. The aim of this study is to determine whether the KIS approach can effectively treat PCS while minimising the number of treated veins and coils used, without the need for injecting sclerosing agents into pelvic veins or the use of occlusion balloons.MethodsThis is a single‐institution retrospective cohort study. Our records identified 154 women who underwent venograms for possible PCS, with the intent to proceed with embolisation. Refluxing veins were treated using the KIS approach, deploying minimal number of coils, ‘sandwiching’ sclerosing foam. Short‐term follow‐up was conducted at 6 weeks; long‐term follow‐ups (between 12 and 60 months) were conducted via an electronic survey consisting of 19 questions assessing pelvic pain/pressure, leg and back pain, fatigue, and bladder and menstrual symptoms.ResultsFifteen women had negative venogram; 139 women had one or more refluxing veins on venogram. Most women (73%) required unilateral ovarian vein (OV) embolisation, 14% required bilateral OV embolisation, and 12% underwent pelvic vein embolisation. Most cases required only four pushable coils. Clinical success was 89% at 6 weeks and 84% at 1–5 years. A visual analogue scale reduction of 5.2 points (from 7.8 to 2.7) was achieved. There were no instances of coil dislodgement or other complications.ConclusionThe keep‐it‐simple approach, embolising only the refluxing ovarian and/or iliac veins, can achieve a successful clinical outcome for pelvic congestion syndrome. The extensive approach of empirically embolising all ovarian veins and internal iliac veins may not be necessary. This carries implications for potential savings in procedure time, cost and radiation dose.
Diagnostic reasoning and cognitive error in emergency medicine: Implications for teaching and learning
Authors: Pelaccia Thierry , Sherbino Jonathan , Wyer Peter , Norman Geoff 
Published: October 2024

AbstractBackgroundAccurate diagnosis in emergency medicine (EM) is high stakes and challenging. Research into physicians’ clinical reasoning has been ongoing since the late 1970s. The dual‐process theory has established itself as a valid model, including in EM. It is based on the distinction between two information‐processing systems. System 1 rapidly generates one or more diagnostic hypotheses almost instantaneously, driven by experiential knowledge, while System 2 proceeds more slowly and analytically, applying formal rules to arrive at a final diagnosis.MethodsWe reviewed the literature on dual‐process theory in the fields of cognitive science, medical education and emergency medicine.Results and ConclusionThe literature reflects two prominent interpretations regarding the relationship between the fast and slow phases and these interpretations carry very different implications for the training of clinical learners. One interpretation, prominent in the EM community, presents it as a “check‐and‐balance” framework in which most diagnostic error is caused by cognitive biases originating within System 1. As a result, EM residents are frequently advised to deploy analytical (System 2) strategies to correct such biases. However, such teaching approaches are not supported by research into the nature of diagnostic reasoning. An alternative interpretation assumes a harmonious relationship between Systems 1 and 2 in which both fast and slow processes are driven by underlying knowledge that conditions performance and the occurrence of errors. Educational strategies corresponding to this alternative have not been explored in the EM literature. In this paper, we offer proposals for improving the teaching and learning of diagnostic reasoning by EM residents.

Published: October 2024

BackgroundWomen with substance use disorders (SUD) use less contraception, and experience higher rates of unintended pregnancy, compared to women without SUD. Contraception is discussed at the six‐week postnatal appointment, which many women with SUD do not attend. Therefore, it is important women have the opportunity to formulate contraception plans before discharge from the birth admission.AimsTo assess postpartum contraception plans, including initiation and method of interest, among women with SUD and compare these to women without SUD.Materials and MethodsAll births from January 2011 to September 2019 from one New South Wales local health district were analysed. Data included maternal demographics, SUD, and contraception plans. Chi‐squared statistics and multivariate multinomial regression analyses were used to compare outcomes for women with and without SUD.ResultsOf 59 195 mothers, 429 (0.7%) had a SUD. There were 50.1% of women with SUD and 56.2% without SUD (P = 0.03) who had no documented plan for contraception. There were 37.3% of women with SUD and 42.4% without SUD (P = 0.06) who had a prescription for contraception or a referral to discuss contraception. There were 12.5% of women with SUD and 1.4% without SUD (P < 0.001) who initiated contraception in hospital.ConclusionsAlthough postpartum contraception initiation was higher among women with SUD, half of all women (with or without SUD) were discharged without a plan for contraception initiation. Embedding provision of postpartum contraception into maternity care, or investigating other opportunities, may improve access for all women, including those with SUD.

Published: October 2024

AbstractBackgroundNon‐tuberculous mycobacteria (NTM) are rare causes of bone and joint infection (BJI) and there is limited evidence on which to base management decisions. This study describes 1 year of experience from a multi‐disciplinary BJI team which collects data on all cases reviewed at a tertiary referral centre in Queensland, Australia.MethodsThe database was interrogated for all cases in which NTM were recovered from operative samples. Individual chart review was performed to collect the details of each case.ResultsA total of seven cases were managed between 1st February 2021 and 28th February 2022, comprising one patient with chronic osteomyelitis, three with fracture‐related infections, two with prosthetic joint infections, and one with infection of a synthetic ligament graft. In contrast to pulmonary NTM infections, most patients were clinically well and immunocompetent, and most infections were propagated by direct inoculation. Time to diagnosis was unknown in three patients, with 1, 2, 2, and 5 months for the remaining four. Rapid growing NTM were diagnosed on routine cultures and specific mycobacterial cultures were confirmatory. Management was characterized by multiple stage surgical procedures and prolonged antimicrobial regimens.ConclusionsAntimicrobial complications were common; however, all patients were infection free at their latest follow up. Despite the inherent limitations, these results suggest that routinely ordering mycobacterial culture is of low yield. There is potential for shorter‐term oral antimicrobial treatments. Prospective research is required to optimize treatment regimens and durations.
Vitamin D intake and status in children and adolescents: Comparing vegetarian, vegan, and omnivorous diets
Authors: Devulapalli Chandra Sekhar 
Published: October 2024

AbstractAimThis study aimed to evaluate papers analysing dietary intake, 25‐hydroxyvitamin D (25(OH)D) concentrations and anthropometry in children on vegetarian, vegan and omnivorous diets, as research indicates all diets generally fall below recommended vitamin D intake.MethodsThis mini review examined the vitamin D status of children aged 1–18 years by systematically searching PubMed, Google Scholar and Scopus databases from January 1, 2000, to December 31, 2023.ResultsThe review included nine studies published between 2000 and 2023. Four studies reported lower vitamin D intake in children on vegetarian and vegan diets compared to omnivores. Three studies reported lower 25(OH)D concentrations in children on vegetarian and vegan diets. Specifically, one study found lower concentrations in vegans compared to omnivores, another found lower concentrations in vegetarians and vegans not taking supplements and a third reported lower 25(OH)D concentrations in Asian children aged 3–4.5 years compared to Caucasian children. Three studies found no significant differences in 25(OH)D between diet groups. Three studies assessing anthropometry showed that vegetarians have similar body weight and height as omnivores.ConclusionChildren across all dietary groups may have low vitamin D intakes; supplementation should be considered for those with inadequate sun exposure, especially those avoiding animal products.

SummaryThe optimal treatment strategy for adult Langerhans cell histiocytosis (LCH) remains unclear. Our previous study demonstrated the remarkable efficacy of combined methotrexate and cytarabine (Ara‐C) [MA] therapy in patients newly diagnosed with LCH, with a median follow‐up of 2 years. The present article reports long‐term follow‐up data spanning a median of 78 months (6.5 years) from a single‐arm, single‐centre, prospective phase 2 clinical trial (NCT 02389400) conducted between January 2014 and December 2020. Ninety‐five adults with newly diagnosed LCH exhibiting multisystem disease or multifocal single‐system involvement underwent MA therapy every 35 days for six cycles. Methotrexate (1 g/m2) was administered by 24 h infusion on day 1 and AraC (0.1 g/m2) by 24 h infusion for 5 days. The primary end‐point was event‐free survival (EFS). The median patient age was 32 years (range 18–65 years). The overall response rate was 89.5%. Seven patients in this cohort died, and 38 experienced disease reactivation. No degenerative central nervous system diseases were observed. The estimated 6‐year overall survival (OS) and EFS rates were 93.2% and 55.2% respectively. Multivariate analysis revealed that risk organ (RO) involvement at baseline (hazard ratio [HR] 6.135 [95% confidence interval (CI) 1.185–32.259]; p = 0.031) and age >40 years at diagnosis (HR 7.299 [95% CI 1.056–21.277]; p = 0.042) were associated with inferior OS. RO (HR 2.604 [95% CI 1.418–4.762]; p = 0.002) and skin (HR 2.232 [95% CI 1.171–4.255]; p = 0.015) involvement at baseline were poor prognostic factors for EFS. Regarding adverse events, four patients developed a second primary malignancy. In conclusion, the MA regimen was a valid and safe therapeutic approach for adult patients newly diagnosed with LCH.
The role of the Messinian evaporites in the identification of potential gas storage sites: A review of the Adriatic foreland basin system (Italy)

Published: October 2024

AbstractFocusing on the late Miocene stratigraphic successions including the evaporite deposits from the Messinian salinity crisis (MSC) of the Adriatic foreland basin, a revision of available boreholes and seismic data allowed us to recognize the presence of reservoirs and seals systems that can be considered of potential interest for the storage of natural and synthetic gas. Potentially good reservoir sites can be found where porous rocks referable to siliciclastic turbiditites (Marnoso‐arenacea and Laga Fms) or shallow‐water carbonates (Bolognano Fm) preferentially involved in anticlinal structures and covered by thick MSC evaporites, which may represent effective reservoir seals. The integrated reconstruction of porous rocks distribution and facies, thickness, and lateral continuity of the overlying evaporites, allows the identification and zonation of geological settings in the Adriatic foredeep, backbulge and foreland with peculiar stratigraphy and deformations, only partially considered before, that may deserve consideration in the research of potential gas storage sites.
