Service system resilience under resource scarcity: from vulnerability to balanced centricity
Authors: Leino Henna M. , Davey Janet , Johns Raechel 
Published: November 2023

Purpose
Disruptive shocks significantly compromise service contexts, challenging multidimensional value (co)creation. Recent focus has been on consumers experiencing vulnerability in service contexts. However, the susceptibility of service firms, employees and other actors to the impacts of disruptive shocks has received little attention. Since resource scarcity from disruptive shocks heightens tensions around balancing different needs in the service system, this paper aims to propose a framework of balanced centricity and service system resilience for service sustainability.

Design/methodology/approach
Adopting a conceptual model process, the paper integrates resilience and balanced centricity (method theories) with customer/consumer vulnerability (domain theory) resulting in a definition of multiactor vulnerability and related theoretical propositions.

Findings
Depleted, unavailable, or competed over resources among multiple actors constrain resource integration. Disruptive shocks nevertheless have upside potential. The interdependencies of actors in the service system call for deeper examination of multiple parties’ susceptibility to disruptive resource scarcity. The conceptual framework integrates multiactor vulnerability (when multiactor susceptibility to resource scarcity challenges value exchange) with processes of service system resilience, developing three research propositions. Emerging research questions and strategies for balanced centricity provide a research agenda.

Research limitations/implications
A multiactor, balanced centricity perspective extends understanding of value cocreation, service resilience and service sustainability. Strategies for anticipating, coping with and adapting to disruptions in service systems are suggested by using the balanced centricity perspective, offering the potential to maintain (or enhance) the six types of value.

Originality/value
This research defines multiactor vulnerability, extending work on experienced vulnerabilities; describes the multilevel and multiactor perspective on experienced vulnerability in service relationships; and conceptualizes how balanced centricity can decrease multiactor vulnerability and increase service system resilience when mega disruptions occur.
Impact of indirect taxes on CO2 emissions in the presence of institutional quality: evidence from a global panel data analysis
Authors: Ebaidalla Ebaidalla M. 
Published: November 2023

PurposeDespite the importance of tax policy in reducing energy consumption and carbon emissions, there is a dearth of research on the environmental impact of indirect taxes. This paper examines the impact of indirect taxes on carbon dioxide (CO2) emissions, with an emphasis on institutional quality.Design/methodology/approachThe study uses the Government Revenue Dataset (2021), comprising 143 countries, dividing into 114 developing and 29 developed countries, during the period between 1996 and 2019. The author adopts panel data techniques, with Driscoll–Kraay standard errors to account for the issue of cross-sectional dependence (CSD).FindingsThe results indicate that indirect tax revenues have a negative and significant impact on CO2 emissions for the total sample. The subsample analysis revealed that while indirect taxes reduce carbon emissions in developing countries, opposed results are reported for developed countries. This finding implies that most of the advanced countries have already reached a high level of taxes, at which carbon emissions increase as indirect tax increases further. Interestingly, the results revealed that institutional quality enhances the role of indirect taxes in mitigating carbon emissions for both developing and developed countries.Originality/valueTo the best of the authors' knowledge, this is the sole study using the newly developed tax data by the United Nations University, World Institute for Development Research (UNU-WIDER) to investigate the impact of indirect taxes on carbon emissions, with an emphasis on institutional quality. The existing literature focuses on specific taxes, like carbon taxes, with no comprehensive research on the link between indirect taxes and carbon emissions.
Synthesis and adsorption performance of temperature-sensitive imprinted composite poly (vinylidene fluoride) resin membranes with chitosan modification for selective separation of ReO4−
Authors: Xu Wan , Liu Xinsheng , Zhang Huijuan , Huo Ting , Chen Zhenbin , Sun Yuan 
Published: November 2023

Purpose
This study aims to prepare an imprinted composite membrane with grafted temperature-sensitive blocks for the efficient adsorption and separation of rhenium(Re) from aqueous solutions.

Design/methodology/approach
PVDF resin membrane was used as the substrate, dopamine and chitosan (CS) were used to modify the membrane surface and temperature-sensitive block PDEA was grafted on the membrane surface. Then acrylic acid (AA) and N-methylol acrylamide (N-MAM) were used as the functional monomers, ethyleneglycol dimethacrylate (EGDMA) as the cross-linker and ascorbic acid-hydrogen peroxide (Vc-H2O2) as the initiator to obtain the temperature-sensitive ReO4− imprinted composite membranes.

Findings
The effect of the preparation process on the performance of CS–Re–TIICM was investigated in detail, and the optimal preparation conditions were as follows: the molar ratios of AA–NH4ReO4, N-MAM and EGDMA were 0.13, 0.60 and 1.00, respectively. The optimal temperature and time of the reaction were 40 °C and 24 h. The maximum adsorption capacity of CS–Re–TIICM prepared under optimal conditions was 0.1071 mmol/g, and the separation was 3.90 when MnO4− was used as the interfering ion. The quasi first-order kinetics model and Langmuir model were more suitable to describe the adsorption process.

Practical implications
With the increasing demand for Re, the recovery of Re from Re-containing secondary resources becomes important. This study demonstrated a new material that could be separated and recovered Re in a complex environment, which could effectively alleviate the conflict between the supply and demand of Re.

Originality/value
This contribution provided a new material for the selective separation and purification of ReO4−, and the adsorption capacity and separation of CS–Re–TIICM were increased with 1.673 times and 1.219 time compared with other Re adsorbents, respectively. In addition, when it was used for the purification of NH4ReO4 crude, the purity was increased from 91.950% to 99.999%.
Study on the mechanism and performance of 3D-printed PLA/epoxy composite for stab resistance
Authors: Du Zhe , Chen Changjie , Wang Xinhou 
Published: November 2023

Purpose
Stab-resistant body armor (SRBA) is used to protect the body from sharp knives. However, most SRBA materials currently have the disadvantages of large weight and thickness. This paper aims to prepare lightweight and high-performance SRBA by 3D printing truss structure and resin-filling method.

Design/methodology/approach
The stab resistance truss structure was prepared by the fused deposition modeling method, and the composite structure was formed after filling with resin for dynamic and quasi-static stab tests. The optimized structural plate can meet the standard GA68-2019. Digital image correlation technology was used to analyze the local strain changes during puncture. The puncture failure mode was summarized by the final failure morphologies. The explicit dynamics module in ANSYS Workbench was used to analyze the design of the overlapped structure stab resistance process in this paper.

Findings
The stab resistance performance of the 3D-printed structural plate is affected by the internal filling pattern. The stab resistance performance of 3D-printed structural parts was significantly improved after resin filling. The 50%-diamond-PLA-epoxy, with a thickness of only 5 mm was able to meet the stab resistance standard. Resins are used to increase the strength and hardness of the material but also to increase crack propagation and reduce the toughness of the material. The overlapping semicircular structure was inspired by the exoskeleton structure of the demon iron beetle, which improved the stab resistance between gaps. The truss structure can effectively disperse stress for toughening. The filled resin was reinforced by absorbing impact energy.

Originality/value
The 3D-printed resin-filled truss structure can be used to prepare high-performance stab resistance structural plates, which balance the toughness and strength of the overall structure and ultimately reduce the thickness and weight of the SRBA.

Authors: Vega Chica Mayra Liuviana , Valle Lituma Luis Ángel 
Published: November 2023

Purpose
This study aims to explore the mediating role of the motivation for learning in knowledge acquisition and knowledge transfer in students of higher education programs in business and management.

Design/methodology/approach
Quantitative correlational design. Data was collected from a sample of 366 students studying and working in the business and entrepreneurial sector in Ecuador. The instrument used was a Likert scale questionnaire. Correlation analyses were used to specify the relationships between variables. Multiple regression analysis was used to test the hypotheses.

Findings
The results evidenced the mediating effect of the motivation for learning on the relationship between knowledge acquisition and knowledge transfer of undergraduate and graduate students in higher education programs in the area of business and entrepreneurship.

Research limitations/implications
The model investigated is a contribution to the literature since the variables have been little studied by the students as transfer channels, and there is a need to explore these relationships between variables in other productive sectors.

Practical implications
Organizations will be able to identify relevant factors in knowledge transfer, the motivation for learning for the context of working, create ideal conditions for knowledge flow and maintain a commitment to take advantage of this cooperation.

Social implications
The results contribute to the three agents involved in knowledge transfer: students, educational institutions and organizations. Students can have a greater understanding of the skills they need to improve their learning and application of knowledge. Educational institutions will have a better understanding of and approach to developing competencies in their students.

Originality/value
This simple regression model enriches the current literature on the mediating effect of the motivation for learning on the relationship between knowledge acquisition and knowledge transfer in higher education institutions in Latin American countries.
Common home hazards among healthy older aged adults and potential modifications required for age‐friendly housing
Authors: Aclan Roslyn , George Stacey , Laver Kate 
Published: November 2023

AbstractIntroductionThe creation of age‐friendly home environments enables middle‐aged and older aged people to live independently at home while adapting to age‐related changes. Little is currently known about existing home hazards that may potentially hinder healthy older people as they age.MethodsProspective cohort study of healthy adults who received an age‐friendly home environment assessment conducted by an occupational therapist. Adults aged 60 and over, without significant disability, living in homes within metropolitan Adelaide, South Australia were recruited through community advertising.ResultsSixty age‐friendly home environment assessments were conducted. Common areas where potential hazards were identified, and modifications recommended were bathrooms, toilets and backyards. Gardens were commonly identified as potentially requiring modifications in the future. Participants were more likely to consider moving to new housing if additional modifications were needed to their homes.ConclusionAffordable and accessible age‐friendly housing is required to support an ageing population. Education on age‐friendly housing for healthy middle and older aged people is required enabling proactive planning rather than awaiting health crises.
Impartiality in Public Broadcasting
Authors: Sambrook Richard , Cushion Stephen 
Published: November 2023

AbstractImpartiality has been a core principle of public service broadcasting (PSB) in the UK for 100 years. However, it is under growing pressure as audiences increasingly rely on more opinion led content on television and especially online. The hostility towards PSB has been fuelled by politicians and commercial media undermining the value of regulation in the twenty‐first century. The UK regulator, Ofcom, has offered a flexible approach to oversight which the authors argue may have contributed to further confusion over what impartiality is, and its value in a competitive media environment. Greater independence, accountability and transparency—for both broadcasters and regulator—are suggested to be vital to maintaining the value of impartiality in PSB.

AbstractCoastal bottlenose dolphin populations are highly vulnerable due to their small population sizes and proximity to human activities. Long‐term studies in the UK have monitored populations protected within Special Areas of Conservation (SACs) since the 1990s, but a small community of bottlenose dolphins inhabiting the coastal waters of southern England has received much less attention. The English Channel is one of the most heavily impacted marine ecosystems worldwide and increasing anthropogenic pressures pose a severe threat to the long‐term viability of this population. Conservation measures to protect these animals have been hindered by a lack of knowledge of population size, distribution and ranging behaviour. This study aimed to fill these knowledge gaps. A citizen science sighting network yielded 7458 sighting reports of bottlenose dolphins between 2000 and 2020. Resightings of identified individuals were used to estimate abundance, distribution, and ranging behaviour. Social structure analysis revealed a discrete interconnected group of animals in shallow coastal waters, which did not appear to mix with conspecifics identified further offshore. A Bayesian multi‐site mark–recapture analysis estimated that this population comprises around 48 animals (CV = 0.18, 95% HPDI = 38–66). These dolphins ranged between North Cornwall and Sussex, with an average individual range of 530 km (68–760 km). Areas of high‐modelled habitat suitability were found to overlap with high levels of anthropogenic pressure, with pollution and boat traffic identified as the most pervasive threats. Although adult survival rates indicated that the population was relatively stable from 2008 to 2019 (0.945 (0.017 ± SE)), the small population size implies a significant risk to their long‐term viability and resilience to environmental change. By highlighting the most deleterious anthropogenic activities and regions of conservation significance, our results will be useful for developing management policies for threat mitigation and population conservation, to protect this vulnerable group of dolphins.
A de novo variant in RERE causes autistic behavior by disrupting related genes and signaling pathway

Published: November 2023

AbstractAutism spectrum disorder (ASD) is a highly variable neurodevelopmental disorder that typically manifests childhood, characterized by a triad of symptoms: impaired social interaction, communication difficulties, and restricted interests with repetitive behaviors. De novo variants in related genes can cause ASD. We present the case of a 6‐year‐old Chinese boy with autistic behavior, including language communication impairments, intellectual disabilities, stunted development, and irritability in social interactions. Using Sanger sequencing, we confirmed a pathogenic in the RERE gene (NM_012102.4) (c.3732delC, p.Tyr1245Thrfs*12; EX21; Het). Subsequently, we generated an RERE point mutation cell line (ReMut) using CRISPR/Cas9 Targeted Genome Editing. Immunofluorescence was conducted to determine the location of the mutant RERE. RNA‐sequencing and mass spectrometry analyses were performed to elucidate the ASD‐related genes and signaling pathways disrupted by this variant in RERE. We identified 3790 differentially expressed genes and 684 differentially expressed proteins. The SHH signaling pathway was found to be downregulated, and the Hippo pathway was upregulated in ReMut. Genes implicated in autism, such as CNTNAP2, STX1A, FARP2, and GPC1, were significantly downregulated. Simultaneously, we noted alterations in HDAC1 and HDAC2, which are members of the WHHERE complex, suggesting their role in the pathogenesis of this patient. In conclusion, we report a de novo variant in RERE associated with autistic behavior. The finding that ASD is associated with RERE variants underscore the role of genetic factors in ASD and provides insights regarding the mechanisms underlying RERE variants in disease onset.
Trends in alcohol‐related harm among Swedish youth: Do in‐patient care registry data match drinking trends?
Authors: Stafström Martin , Raninen Jonas 
Published: November 2023

AbstractIntroductionYouth drinking has been declining in Sweden since the year 2000. There is a paucity of studies examining trends in alcohol‐related harm during this period. The overall aim of the present study is to examine how trends in alcohol‐related harm match trends in drinking among Swedish youths during 2000–2021.MethodsMeasures of alcohol use were obtained from national school surveys. Prevalence rates of any alcohol use and heavy episodic drinking were used. Alcohol‐related harm indicators were obtained from registry information from the National Board of Health and Welfare. Annual trends in harm indicators were tested with linear regression models and correlations between alcohol use and alcohol‐related harm indicators were assessed using Pearson's correlation on annual data.ResultsStatistically significant negative trends were observed for all alcohol‐related harm indicators for the period 2000–2021. Significant correlations were found for both measures of alcohol use and all alcohol‐related harm indicators.Discussion and ConclusionsThe levels of alcohol‐related harm have declined among youths in Sweden during the period 2000–2021. The trends in harm seem to reflect the decline in youth drinking that has occurred during the same period.
Migratory redhorse suckers provide subsidies of nitrogen but not phosphorus to a spawning stream
Authors: Hudson Ryan R. , Wheeler Kit , White Mack , Murdock Justin N. 
Published: November 2023

AbstractSpawning migrations of fishes are common case studies for examining the magnitude of resource subsidies; however, no studies have evaluated this phenomenon in iteroparous migrations of the Catostomid (i.e. suckers) genus Moxostoma (i.e. redhorses). Fish resource subsidies are usually represented as nitrogen (N) and phosphorus (P), and migratory redhorses can deliver these nutrients via excretion and eggs. We evaluated whether redhorses deliver N and P subsidies to Brasstown Creek—a fourth‐order stream in the Southeastern US—during their spawning migrations. We measured individual‐level nutrient contributions from excretion and eggs and extrapolated those values to estimate nutrient contributions based on daily abundances of migratory redhorses. We compared daily nutrient inputs to daily nutrient exports to determine the potential for resource subsidies. We estimated 71.6 kg of N and 4.4 kg of P were delivered to Brasstown Creek over a 98‐day migration period. N input exceeded N export on 15 of the 98 days, but phosphorus input never exceeded P export. Eggs accounted for the majority of N and P input at 51% and 100% respectively. Redhorse N inputs peaked in the spring during a period of low N exports, suggesting that redhorse subsidies were delivered during times of elevated nutrient demand and relatively low nutrient availability. Suckers receive little management attention, and several species of redhorses are imperilled. Given our conclusion that redhorses provide a temporally critical N subsidy that is likely available to multiple consumers in freshwater food webs, this study provides compelling motivation for increased conservation of these species and their migrations.

Published: November 2023

AbstractHydroxyurea reduces the frequency of vaso‐occlusive complications, increases hemoglobin, and decreases mortality in sickle cell disease (SCD). Although current guidelines recommend escalation to maximum tolerated dose (MTD), the use of fixed low‐dose hydroxyurea is common in low‐resource countries. We conducted a systematic review and meta‐analysis to evaluate the efficacy of escalated doses versus fixed low‐dose of hydroxyurea in adults with SCD. Nine studies were included in the quantitative synthesis, four evaluating fixed low‐dose and five evaluating escalated doses of hydroxyurea. Average daily doses of hydroxyurea in the fixed low‐dose and escalated dose studies were ~10 and 22 mg/kg, respectively. There was no difference in the estimate of vaso‐occlusive crisis rate between escalated and fixed low‐dose studies (p = .73). The mean difference in hemoglobin from baseline to follow‐up was greater for fixed low‐dose than escalated dose studies (1.07 g/dL vs. 0.54 g/dL, p = .01). No difference was seen in the mean estimate of fetal hemoglobin. Despite limited eligible studies and substantial heterogeneity of effect between the studies for several outcomes, there appears to be clinical equipoise regarding the most appropriate hydroxyurea dosing regimen in adults with SCD. Controlled studies of hydroxyurea at MTD versus fixed low‐dose in adults with SCD are required.
