Tribo-mechanical characterization of Cu-Cr-Zr ternary alloy aimed at fin-tube resistance welding electrode material
Authors: Sirsath Kiran G. , Bachchhav Bhanudas D. 
Published: August 2023

PurposeLow performance life and increased machine downtime due to wear of resistance welding copper electrode is of major concern in fin–tube resistance welding in waste heat recovery boilers. The purpose of this study is to investigate an alternative material with good wear resistance to replace the currently utilized C11000 electrolytic tough pitch (ETP) copper electrode.Design/methodology/approachIn this study, a Cu-Cr-Zr ternary alloy was developed for fin-to-tube welding electrode by melting commercial grade electrolytic copper (99.9% purity) plates, chips of chromium, powder of zirconium at 1100°–1300°C, followed by hot forging and precipitation hardening at 450°–550°C to attain appropriate grain flow. Microstructures of Cu-Cr-Zr alloys were analysed using scanning electron microscopy coupled with energy-dispersive backscatter electron spectrometry.FindingsWear performance of Cu-Cr-Zr and C11000 ETP Cu was evaluated using pin-on-disc set-up with Taguchi’s L8orthogonal array. Ranking of the parameters was done, and it was observed that the material and temperature play a very significant role in controlling the wear of an electrode.Practical implicationsRate of fin–tube resistance welding was increased by 26% with Cu-Cr-Zr alloy. Further investigation on effect of plasma on the metallurgical characteristics of Cu-Cr-Zr is recommended.Originality/valueTribo-mechanical performance of newly developed Cu-Cr-Zr ternary alloy was compared with C11000 ETP copper.Peer reviewThe peer review history for this article is available at:https://publons.com/publon/10.1108/ILT-04-2023-0092/
Dynamic capabilities and SMEs competitiveness: the moderating effect of market turbulence
Authors: Al Dhaheri Mariam , Ahmad Syed Zamberi , Abu Bakar Abdul Rahim , Papastathopoulos Avraam 
Published: August 2023

Purpose
This study aims to examine the effectiveness of individual dynamic capabilities (DC) constructs and whether they had comparable effects on a company’s competitiveness in market turbulence (MT). This study used quantitative methods to determine how the DC elements, sensing, learning, integrating and coordinating, influenced competitiveness, with the moderating role of MT during a real-time crisis.

Design/methodology/approach
Survey data was gathered from 426 tourism small and medium-sized enterprises (TSMEs) in the United Arab Emirates and analyzed quantitatively.

Findings
The study found that not all DC constructs were equally important in promoting competitiveness. TSMEs’ survival depended more on sensing and integrating capabilities than learning and coordinating capabilities, and on how these capabilities were used by managers or owners of TSMEs. The study found no moderation effect of MT.

Research limitations/implications
The generalizability of the results was hindered by the study’s focus on TSMEs in a single geographic location. The reasons for lack of proper mobilization of DCs constructs were not explored, but the data on the relative efficacy of DC constructs during a crisis significantly contributed to the literature.

Originality/value
This study emphasized ways that companies could improve firm competitiveness during a crisis by deploying DCs to optimize operations. The implications for research, practical aspects and limitations are presented and discussed.

Authors: Lee Angie , Fiore Ann Marie 
Published: August 2023

PurposeThe purpose of this study was to understand factors affecting market mavens' use of social media for fashion-related information provision. The study examined market mavens' motivations to share fashion-related information. Specifically, this study investigates the impact of their motivations (i.e. pleasure from helping, a sense of obligation) and technology acceptance model variables (i.e. beliefs about and attitude toward using social media) on intention to use social media for sharing fashion-related information.Design/methodology/approachAn online survey yielded 862 responses from US female respondents. A subset (N = 307) representing those high in market mavenism was used for the study. Structural equation modeling was employed for the analysis.FindingsThe results confirmed that market mavens were driven by pleasure from helping and a sense of obligation to share fashion-related information. These motivations and attitude toward using social media to disseminate fashion-related information positively influenced market mavens' intention to use it to disseminate fashion-related information. Furthermore, belief variables (i.e. perceived usefulness, ease of use and enjoyment associated with social media) indirectly impacted this intention.Originality/valueThe study adds to the scant research examining market mavens' motivations for sharing fashion-related information with others and their intention to use social media. It provides valuable insights for fashion retailers looking to enhance the impact of social media marketing through the deployment of market mavens – very knowledgeable, motivated and trusted consumers.

Excess cash or excess headache? Demonetisation and bank behaviour in India
Authors: Majumdar Saumen , Agarwal Swati , Ghosh Saibal 
Published: August 2023

Purpose
Sudden and unannounced policy changes by the government that provide banks with windfall deposits creates a challenge in terms of resource deployment. In the process, there is an impact on their risk and returns. Using data on domestic Indian commercial banks, this study aims to examine the impact of such an announcement – the 2016 demonetisation episode – on bank behaviour.

Design/methodology/approach
Using data on domestic Indian commercial banks during 2010–2020, the paper investigates the effect of a sudden and unannounced policy change on their risk and returns. Using the demonetisation undertaken in November 2016 as a natural experiment, the paper applies the difference-in-differences methodology to tease out the causal impact.

Findings
The findings reveal a decline in risk and an increase in returns of state-owned banks, consistent with a flight-to-safety. The response differed in terms of market and accounting measures and across state-owned banks with differing levels of capital and asset quality.

Originality/value
Although several aspects of the demonetisation episode have been well analysed, its impact on banks – the main conduits of the exercise – and in particular on their risk and returns, is an unaddressed area of research. Viewed from this standpoint, this is one of the early studies to undertake a comprehensive empirical analysis on this aspect.
Supervisors’ experiences of doctoral supervision in times of change
Authors: Löfström Erika , Tikkanen Lotta , Anttila Henrika , Pyhältö Kirsi 
Published: August 2023

Purpose
Empirical evidence on how supervisors have perceived the changes and the implications of the COVID-19 pandemic on their supervision is scarce. This paper aims to examine how the changing landscape of doctoral education has affected supervision from the supervisors’ perspective.

Design/methodology/approach
This survey addressed change, challenges and impact in supervisory responsibilities due to COVID-19 pandemic. The survey was completed by 561 doctoral supervisors from a large multi-field research-intensive university in Finland.

Findings
Results show that supervisors estimated that their supervision had been negatively affected by the pandemic, but to a lesser extent than their doctoral candidates’ progress and well-being. In the changed landscape of supervision, the supervisors grappled with challenges related to recognising doctoral candidates’ need of help. Supervisors’ experiences of the challenges and the impact of changed circumstances varied depending on the field and the position of the supervisor, whether they supervised part- or full-time candidates, and the organisation of supervision.

Practical implications
The slowed-down progression and diminishing well-being of doctoral candidates reported by supervisors is likely to influence supervision in a delayed way. Supervisors may be anticipating some issues with stalled studying and stress, but the question is the extent to which they are prepared to handle these as they emerge in supervision encounters. The fact that the experiences varied across field, position, organisation of supervision and the type of candidates (full or part time) suggests that support provided for supervisors to overcome challenges needs to be tailored and engineered.

Originality/value
This study contributes to the literature on doctoral supervision by exploring the impact of transitioning to online supervision and the rapid changes in doctoral supervision as a consequence of the recent global pandemic.
Should the World Economic Forum’s global tourism competitiveness index be improved?
Authors: Epoh Hervé Honoré , Ewondo Mbebi Olivier , Nzepang Fabrice 
Published: August 2023

Purpose
This research paper aim at providing a new approach of calculating the destinations competitiveness index. How can these variables been aggregated in other to reflect the realities of very distinct productive environments? We assume that: The weighting of variables provides a better measure of destinations competitiveness. Base on the Neo-Technological theory, after a life cycle differentiation, we used a panel data approach to calculate the weight of each variable as the spearman correlation coefficient of its contribution to tourism inflows growth. After integrating these weights, we came to the point that by applying an appropriate weight to its components, we end up having a competitiveness index that significantly improve the correlation between competitiveness and tourism inflows growth.
A case of herpetiform pemphigus mimicking bullous pemphigoid after using secukinumab and successfully treated with sulfasalazine
Authors: Wang Rui , Wang Mingyue 
Published: August 2023

AbstractInterleukin 17A (IL‐17A) inhibitors, such as secukinumab, have been widely used as the mainstream treatment for chronic plaque psoriasis; however, cutaneous adverse events have been reported. Here, we report a 43‐year‐old Chinese man who developed herpetiform pemphigus (HP) during secukinumab treatment for his psoriasis. He presented with (1) clinical features of HP, which resembled bullous pemphigoid; histopathological features of intraepidermal blisters, eosinophilic/neutrophilic spongiosis, and liquefactive degeneration of the basal cell layer; (3) positive anti‐desmoglein 1 antibody by enzyme‐linked immunosorbent assay and cell surface IgG reactivity within the epidermis by indirect immunofluorescence assay; and (4) a satisfactory response to salicylazosulfapyridine (sulfasalazine). To the best of our knowledge, this is the first report of the development of HP after the use of secukinumab for psoriasis.
Short‐ and long‐run impacts of gasoline price and macroeconomic factors on road traffic safety in Nigeria
Authors: Akinyemi Yingigba C. 
Published: August 2023

AbstractThis paper examined the short‐ and long‐run impacts of gasoline price, macroeconomic factors and road length on road traffic crashes, injuries and fatalities in Nigeria. Annual data from 1995 to 2019 and autoregressive distributed lag approach were employed. Results suggest that gasoline price, per capita income, road length and population density significantly influence road safety outcomes. Gasoline price has a positive short‐run impact on crashes, injuries, and fatalities contrary to findings in developed countries. Road crashes tend to decrease when income increases in the short term. Population density leads to improvement in road safety outcomes while road length exacerbates it. Government's policy on gasoline price increase could worsen road safety outcomes unless it is accompanied by improvement in road infrastructure, safe public transport and economic growth,
Behavioural normative economics: foundations, approaches and trends
Authors: Dold Malte 
Published: August 2023

AbstractThis article summarises the theoretical foundations, main approaches and current trends in the field of behavioural normative economics. It identifies bounded rationality and bounded willpower as the two core concepts that have motivated the field. Since the concepts allow for individual preferences to be context‐dependent and time‐inconsistent, they pose an intricate problem for standard welfare analysis. The article discusses the ways in which two prominent approaches – the preference purification approach and the opportunity approach – have tackled the problem. It argues that shortcomings in each of these approaches motivate an agency‐centric perspective. The article presents two concrete policy proposals of the agency‐centric approach. While this approach is promising, the article argues for pluralism in normative economics since an exclusive focus on agency can likely not do justice to the multifarious concerns that citizens hold.
Do remittances align with energy transition in Africa? An approach with the level of income of countries
Authors: Abba Yadou Barnabe , Ntang Philemon Bonaventure , Tchio Tchieutsouah Raisa , Abba Abam‐Nde Valery 
Published: August 2023

AbstractThe main objective of this paper was to highlight the nexus between migrant remittances and energy transition in a panel of 45 African countries from 2000 to 2020. The study utilized several estimation techniques ranging from fixed and random effects to two‐stage least square. The empirical findings suggest that remittances reduce energy transition in African countries. However, the growth of remittances reverses this relationship. There is therefore an U‐shaped relationship between remittances and energy transition in Africa. Furthermore, when disaggregating countries by income level, the results reveal that in low‐income countries, remittances reduce energy transition, but this effect is reversed in low‐ and middle‐income countries. Remittances are therefore a determinant in the choice of households for the process of energy transition. Thus, in order to take advantage of this relationship, African countries need to emphasize policies that can increase the flow of remittances by improving their financial system. In addition, migrant remittances contribute to improving access to modern, reliable, and affordable energy services through income growth of remittance‐receiving households.

AbstractIntroductionPlasma exchange (PE) is widely used in many immune‐based neurological diseases. Our aim is to analyze characteristics of PE in neurological patients at the Clinical Center of Montenegro.MethodsOur study involved neurological patients treated with PE between January 2020 and April 2022.ResultsIn total, 246 PEs were performed in 43 patients. We divided patients into 4 groups according to indications. In 8/9 multiple sclerosis (MS) patients a decrease of Expanded Dysability Status Scale at least 0.5 was verified. In 14/20 Guillain Barre syndrome patients reduction of Hughes was observed. Four patients with myasthenia gravis (MG) were treated with PE. The most heterogeneous group (4) consisted of patients in whom the mechanism of disease development is assumed to be immune system dysregulation. Fourteen patients had any adverse event.ConclusionOur results show that PE is widely used and safe in the treatment of neurological diseases.
Macroinvertebrate conservation in river ecosystems: Challenges, restoration strategies, and integrated management approaches
Authors: Lim Sung‐ho , Do Yuno 
Published: August 2023

AbstractRiver ecosystems face growing threats from human‐induced stressors, resulting in habitat degradation and biodiversity loss. Crucial to these ecosystems, macroinvertebrates maintain river health and functioning. In this review, we examine the challenges confronting macroinvertebrates, explore restoration strategies and management approaches, and shed light on knowledge gaps and future research directions. Habitat degradation, water pollution, climate change, and invasive species are discussed as key challenges. Various restoration strategies, such as in‐stream habitat restoration, flow regime restoration, riparian zone restoration, and connectivity restoration, are evaluated for macroinvertebrate conservation. Integrated catchment management, adaptive management, community‐based management, monitoring, and policy integration are highlighted as essential management approaches, and knowledge gaps in long‐term monitoring, innovative restoration techniques, climate change resilience, and policy incorporation are identified as areas calling for further research. Ultimately, a proactive, adaptable, and cooperative approach to river management will ensure macroinvertebrate conservation and sustainable river ecosystems.
Flood mitigation: Regulatory and hydrologic effectiveness of multicomponent runoff detention at a Southwest Florida site
Authors: Duke L. Donald , Mullen Madison N. , Unger Kallie E. , Rotz Rachel , Thomas Serge 
Published: August 2023

AbstractThis research investigates the capability of hydrological site design to mitigate inland flooding. Empirical data for a target watershed characterize interaction among three hydrologic components: stormwater detention ponds; seasonal wetlands; and soils/groundwater. Findings are (a) stormwater ponds' elevation change in response to precipitation events of a given magnitude varies sharply among storms, such that ponds' pre‐event elevation and forecast precipitation are not reliable to predict ponds' ability to detain runoff sufficiently to avoid downstream flooding; (b) water table elevation is governed partly by long‐term seasonal variation but also responds quickly to specific events, and powerfully affects the system's capacity to detain runoff; (c) water table elevation during wet weather periods common to Southwest Florida can be high enough to breach the soil surface for extended periods, severely reducing the capacity of the system to detain runoff; (d) in the target watershed of the Florida Gulf Coast University campus, depressed surface storage in seasonal wetlands compensates for reduced wet season capacity of ponds and soil storage. That mechanism explains why the campus has successfully mitigated flooding including from high‐precipitation events most prone to produce flooding (intense rate, late wet season events), while some downstream communities with components designed to meet the regulatory minimum have experienced inundation.
Efficacy of osimertinib for lung squamous cell carcinoma with de novo EGFR T790M‐positive: Case report and literature review
Authors: Maeda Chihiro , Shinada Kanako , Murakami Shuji , Saito Haruhiro 
Published: August 2023

AbstractAmong epidermal growth factor receptor (EGFR) mutation‐positive non‐small cell lung cancers, squamous cell carcinoma is less common and shows lower responsiveness to first‐generation EGFR tyrosine kinase inhibitors (TKIs) compared to adenocarcinoma. However, the efficacy of osimertinib for squamous cell carcinoma with EGFR mutations is not well known. This study reports the case of a 57‐year‐old male diagnosed as having stage IIIC squamous cell lung cancer. Oncomine Dx Target Test identified EGFR exon19 deletion and de novo EGFR T790M mutation with variant allele frequencies (VAF) of 21.6% and 25.2%, respectively. The patient was treated with osimertinib after progression on chemoradiotherapy followed by durvalumab, and a partial response was maintained for more than 20 months. To predict EGFR‐TKI efficacy, confirmation of gene mutations and VAF using next‐generation sequencing is helpful.

Published: August 2023

AbstractBackgroundRegional anaesthesia has the benefit of reducing the need for systemic analgesia and therefore, potentially reducing undesired side effects. With the end of the sensory nerve block however, many patients report severe pain that requires therapy with opioids and often compromise the initial opioid sparing effect. This study aimed to characterise the postoperative pain profile and the phenomenon of rebound pain after axillary brachial plexus anaesthesia (RA) compared to general anaesthesia (GA).DesignSingle‐centre observational, stratified cohort study.SettingThe study was conducted at University Hospital Marburg from May 2020 until September 2022.ParticipantsOne hundred thirty‐two patients receiving elective hand and forearm surgery were enrolled in this study.InterventionsGroup RA received ultrasound‐guided brachial plexus anaesthesia via the axillary approach with 30 mL of prilocaine 1% and 10 mL ropivacaine 0.2%. Group GA received balanced or total intravenous general anaesthesia.Main Outcome MeasuresPrimary endpoint were integrated pain scores (IPS) within 24 h postoperatively. Secondary endpoints were pain scores (NRS 0–10), morphine equivalents, patient satisfaction, quality of recovery and opioid‐related side effects.ResultsOne hundred thirty‐two patients were analysed of which 66 patients received brachial plexus block and 66 patients received general anaesthesia. Following RA significantly lower IPS were seen directly after surgery (p < .001) and during the post‐anaesthesia care unit interval (p < .001) but equalised after 3 h at the ward. No overshoot in pain scores or increased opioid consumption could be detected. Patient satisfaction and postoperative recovery were comparable between both groups.ConclusionThe IPS and NRS was initially lower in the RA group, increased with fading of the block until equal to the GA group and equal thereafter. Although various definitions of rebound pain were met during this phase, the opioid sparing effect of regional anaesthesia was not counteracted by it. The incidence of episodes with uncontrolled, severe pain did not differ between groups. We found no clinical implications of rebound pain in this setting, since the RA group did not show higher pain scores than the GA group at any time point.Trial Registration: German Clinical Trials Register (DRKS00021764).
