Published: September 2024

Purpose
This study aims to explore the impact of different contextual factors and their interactions on university students' entrepreneurship, specifically start-up activities.

Design/methodology/approach
The paper used a multilevel hierarchical model with four contextual factors: i) industry and technological, ii) institutional and policy, iii) organizational-university; and iv) cultural. Each of these factors might influence university students’ start-up activities differently. To address this exploratory direction, the study used a sample of 34,200 nascent entrepreneurs from 34 countries included in the Global University Entrepreneurial Spirit students’ Survey, along with data from the World Economic Forum’s Global Competitiveness Index, Global Entrepreneurship Index and Global Leadership and Organizational Behavior Effectiveness Index.

Findings
The results show that, in general terms, contextual elements impact university students’ start-up activities. Nevertheless, when these factors are combined, their effect increases strongly with the performance-based culture but decreases with a high level of a socially supportive culture.

Originality/value
Regarding the study of university students’ start-up activities, most scientific evidence has an individual-level approach without considering the influence of the context. The paper adopts a multilevel approach for such analysis to reflect the multilevel and context-dependent nature of the topic under study.

Published: September 2024

Purpose
The purpose of this study is to improve the mechanical properties, thermal insulation properties and flame retardant properties of polyethylene terephthalate (PET), the organic montmorillonite (OMMT)/SiO2 aerogel/PET composites and fibers were prepared, and the effects of the OMMT/SiO2 aerogel on the structure, thermal conductivity and flame retardance of the OMMT/SiO2 aerogel/PET composites and their fibers were systematically investigated.

Design/methodology/approach
The OMMT/SiO2 aerogel/PET composites and fibers were prepared by in-situ polymerization and melt spinning using SiO2 aerogel as thermal insulation filler and OMMT (DK2) as comodified filler.

Findings
The experimental results showed that OMMT improved the crystallization properties of PET. Compared with the crystallinity of SiO2 aerogel/PET composites (34.8%), SiO2 aerogel/PET composites and their fibers reached 45.1% and 49.2%, respectively. The breaking strength of the OMMT/SiO2 aerogel/PET composite fibers were gradually increased with the OMMT content. When the content of OMMT was 0.8 wt.%, the fracture strength of the composite fibers reached 4.40 cN/dtex, which was 54% higher than that of the SiO2 aerogel/PET fiber. In addition, the thermal insulation properties of the composites and their fibers were improved by addition of fillers, and at the same time reached the flame retardant level. The thermal conductivity of the 0.8 wt.% OMMT/SiO2 aerogel/PET composites was 101.78 mW/(m·K), which was 49.3% and 58.8% lower than that of the SiO2 aerogel/PET composites and the pure PET, respectively. The thermal conductivity of the fiber fabrics woven from the 0.8 wt.% OMMT/SiO2 aerogel/PET composites was 28.18 mW/(m·K), which was 29.0% and 44.6% lower than that of the SiO2 aerogel/PET composite fiber fabrics and PET fiber fabrics. The flame retardancy of the composites was improved, with an limiting oxygen index value of 29.2% for the 0.8 wt.% OMMT/SiO2 aerogel/PET composites, which was 4.1% higher compared to the SiO2 aerogel/PET composites, and achieved the flame retardant level.

Research limitations/implications
The SiO2 aerogel/PET composites and their fibers have good mechanical properties, flame retardant properties and thermal insulation properties, exhibited good potential for application in the field of thermal insulation, such as warm clothing. Nowadays, as the energy crisis is becoming more and more serious, it is very important to improve the thermal insulation properties of PET to reduce energy losses and mitigate the energy crisis.

Originality/value
In this study, PET based composites and their fibers with excellent mechanical properties, thermal insulation properties and flame retardant property were obtained by using three-dimensional network porous silica aerogel with low density and low thermal conductivity as the thermal insulation functional filler and two-dimensional layered OMMT as the synergetic modified filler.

Published: September 2024

PurposeOnline brand communities (OBCs) and their role in determining consumer behavior is gathering interest of theorists and practitioners. This study examines the role of OBCs in influencing the level of involvement leading to perceived sport team brand equity (STBE) of sports fans from a social exchange theory perspective. The role of self-congruity as a moderator is examined to determine the differences in the level of involvement and attachment of fans in OBCs.Design/methodology/approachBased on quantitative research and convenience sampling, data for the study were collected from 394 football fans who were existing members of OBCs. The research model is tested using partial least square structural equation modeling.FindingsThe results show a direct and significant impact of brand involvement on brand attachment. Consumer brand engagement (CBE) mediates the relationship between brand attachment and STBE. While self-congruence does moderate the effects between brand involvement and brand attachment.Originality/valueThe study reveals the role of community related factors on sports fans’ perceived STBE. The study also provided a novel approach to examine sport fan behavior in social media through the lens of social exchange theory. Finally, it is providing a novel approach in examining role of OBCs in influencing behavior of sports team fans towards the team and brand.
The protective power of hope and belonging in the workplace
Authors: Smith Brad 
Published: September 2024

Purpose
In today’s turbulent and demanding work environment, the negative effects of workplace stress and strain on employee health and organizational productivity have been well-documented. Positive organizational scholarship has increasingly highlighted the importance of fostering psychological resources that can help buffer against such strains and facilitate employee thriving, resilience and performance. Hope and belonging are two key workplace resources that the mental health and retention effects of which have not been fully explored. The purpose of this paper is to highlight the potential value of both hope and belonging as critical workplace psychological resources that may help employees optimize mental well-being and employers improve retention and productivity.

Design/methodology/approach
The authors collected responses to an online questionnaire distributed in January 2024 to employees drawn from meQuilibrium customers. The final sample consisted of 5,989 employed adults ages 18 and over.

Findings
Among participants, intrinsic hope was more commonly reported than hope derived from extrinsic sources. These data show that high levels of internal or intrinsic hope correlate with reduced anxiety and depression risks. Internal hope also significantly lowers quiet quitting and turnover intent. Among participants, a strong sense of belonging correlates with lower risks of anxiety and depression.

Originality/value
To the best of the author’s knowledge, this paper is the first to investigate the value of hope for employee well-being, retention and performance and adds to the literature on belonging at work.

Published: September 2024

AbstractSponge microbiomes are often highly diverse making it difficult to determine which lineages are important for maintaining host health and homeostasis. Characterising genomic traits associated with symbiosis can improve our knowledge of which lineages have adapted to their host and what functions they might provide. Here we examined five microbial families associated with sponges that have previously shown evidence of cophylogeny, including Endozoicomonadaceae, Nitrosopumilaceae, Spirochaetaceae, Microtrichaceae and Thermoanaerobaculaceae, to better understand the mechanisms behind their symbiosis. We compared sponge‐associated genomes to genomes found in other environments and found that sponge‐specific clades were enriched in genes encoding many known mechanisms for symbiont survival, such as avoiding phagocytosis and defence against foreign genetic elements. We expand on previous knowledge to show that glycosyl hydrolases with sulfatases and sulfotransferases likely form multienzyme degradation pathways to break and remodel sulfated polysaccharides and reveal an enrichment in superoxide dismutase that may prevent damage from free oxygen radicals produced by the host. Finally, we identified novel traits in sponge‐associated symbionts, such as urea metabolism in Spirochaetaceae which was previously shown to be rare in the phylum Spirochaetota. These results identify putative mechanisms by which symbionts have adapted to living in association with sponges.
Pre‐hospital ‘dirty adrenaline’: A descriptive case series of patients receiving peripheral dilute adrenaline infusions in Central Australian remote nurse‐led clinics prior to aeromedical retrieval
Authors: Braham David , Adams Daniel W S , Johnson Richard 
Published: September 2024

AbstractObjectives‘Dirty adrenaline’ is the informal term used for a rapidly made peripheral dilute adrenaline infusion in the emergency treatment of shock, most commonly 1 mg adrenaline in 1 L 0.9% NaCl. It has long been part of the remote clinician's arsenal despite no supporting scientific literature. Remote clinics in Central Australia can be hours away from critical care support. The region's high prevalence of renal and cardiac disease means that access to early vasopressors and inotropes is a necessity for treating shock. To tackle this, remote clinicians often use ‘dirty adrenaline’. We present a review of ‘dirty adrenaline’ use in this region.MethodsCentral Australian Retrieval Service's database was screened to identify cases in which a peripheral dilute adrenaline infusion was administered in a remote clinic prior to patient aeromedical retrieval. A retrospective chart review collected: patient demographics; clinical characteristics; infusion details; adverse events; hospital lengths of stay; and mortality outcomes.ResultsFifty‐seven cases were identified. Median patient age was 50 (range: 2–96). Septic shock was the most common clinical indication (40/57). Median infusion duration was 155 min. Median systolic BP from commencement until retrieval increased from 75.5 to 91 mmHg. Survival to hospital discharge was 86% (49/57). No significant adverse events associated with ‘dirty adrenaline’ were recorded.Conclusion‘Dirty adrenaline’ is safe to administer and appears to considerably improve survival when used to treat fluid‐resistant shock in remote nurse‐led clinics guided by an off‐site critical care physician.

Published: September 2024

AbstractOlive anthracnose induced by different Colletotrichum species causes dramatic losses of fruit yield and oil quality. The increasing incidence of Colletotrichum fioriniae (Colletotrichum acutatum species complex) as causal agent of olive anthracnose in Italy, is endorsing new studies on its biology, ecology, and environmental factors such as temperature. Five isolates from different sampling sites in Lazio region (Central Italy) were studied under controlled laboratory conditions aiming to better understand the differences of thermal development among the isolates and to lay the foundations of a future mathematical model able to describe the key aspects of the pathogen's life cycle. The mycelial growth rate and the conidial germination rate were assessed at seven different constant temperatures (5, 10, 15, 20, 25, 30, and 35°C) and fixed relative humidity (100% RH). The obtained dataset was analysed to estimate the parameters of mathematical functions that connect the mycelial growth rate and the spore germination with the environmental temperature. The parameters set provided as the result of this study constitute a key step forward in the biological knowledge of the species and the basis for future formulations of mathematical models that might be the core of decision support systems in an integrated pest management framework.

Authors: Andreacchi Alessandra T. , Hobin Erin , Siddiqi Arjumand , Smith Brendan T. 
Published: September 2024

AbstractBackground and AimsHeavy episodic drinking (HED) trends have not been comprehensively examined in Canada. We measured age, period and birth cohort trends in HED in Canada by sex/gender and socioeconomic position.Design and setting.We analyzed repeat cross‐sectional data from the 10 provinces in the Canadian Community Health Surveys from 2000 to 2021 using hierarchical cross‐classified random effects logistic regression.Participants1 167 831 respondents aged 12+ .MeasurementsHED was defined as 4+ standard drinks for women or 5+ for men at least monthly in the past 12 months. Socioeconomic position was measured using household income and education.FindingsWe observed steeper HED decreases in young adult men (aged 18–29) than women (by 14.4% and 8.7%, respectively, from 2015 to 2021) and HED increases in middle adult women (ages 50–64) (by 8.0% from 2000 to 2014). Sex/gender‐specific age‐period‐cohort models revealed strong age and birth cohort effects. In women and men, respectively, HED peaked in young adulthood (18.2% and 33.8%) and decreased with age, and HED was greatest in the 1980–1989 cohort (20.7% and 35.8%) and decreased in the most recent cohort born in 1990–2009 (15.6% and 19.8%), particularly in men. Higher household incomes had greater HED across age, periods and cohorts, while trends varied by education. Compared with lower education groups, people with a bachelor's degree or above had the lowest HED in middle adulthood. People with a bachelor's degree or above had low HED in earlier cohorts, which converged with other education groups in recent cohorts due to a pronounced HED increase, particularly in women.ConclusionThe sex/gender gap in heavy episodic drinking (HED) appears to be converging in Canada: current young adult men are reducing HED, while high‐risk cohorts of women are aging into middle adulthood with greater HED. Recent birth cohorts with a bachelor's degree or above experienced pronounced HED increases, which among women suggests greater educational attainment contributes to the converging gender gap in HED.

SummaryBackground and AimsThe prognostic impact of previous‐HBV‐infection (pHBV) in non‐HBV‐related hepatocellular carcinoma (non‐HBV‐related‐HCC) and the prevalence, characteristics and significance of recently developed high‐sensitivity HBs antigen positivity (hHBsAg+) in these patients remain unclear. We aimed to close these gaps.MethodsWe retrospectively screened patients with newly diagnosed non‐HBV‐related‐HCC (standard HBsAg‐test negative) at Hokkaido University. Patients with complete clinical information and preserved serum for hHBsAg+ were included. We evaluated the prevalence, characteristics and prognostic impact of pHBV and hHBsAg+ in non‐HBV‐related‐HCC.ResultsA total of 401 non‐HBV‐related‐HCC patients were included (288 with pHBV/113 without pHBV). In non‐HBV‐related‐HCC, pHBV did not affect overall survival (OS). Among non‐HBV‐related‐HCC patients with pHBV, 11.8% (34/288) were hHBsAg+ and had more advanced stages of HCC, higher AFP levels, higher vascular invasion rates, and significantly shorter OS than others (OS: 19.3 vs. 61.4 months, p = 0.012). Comparison of OS among non‐HBV‐related‐HCC patients without pHBV (group 1), those with pHBV and without hHBsAg+ (group 2), and those with pHBV and hHBsAg+ (group 3) revealed significantly shorter OS in group 3 (19.3, 56.6 and 66.4 months in groups 1, 2 and 3, respectively; p = 0.036). Multivariate Cox regression indicated that compared with group 1, only group 3 was significantly and independently associated with shorter OS (HR: 2.044, p = 0.011). Subgroup analysis revealed that this association was particularly evident in non‐HBV‐related‐HCC patients with non‐B‐non‐C aetiology and advanced HCC.ConclusionsIn non‐HBV‐related‐HCC patients, hHBsAg+, not pHBV, is significantly and independently associated with poor prognosis.
Slow violence on the Yarmouk River: Encounters from the river‐border environments
Authors: Dajani Muna 
Published: September 2024

AbstractThis paper aims to disrupt hegemonic ideas in transboundary water governance literature about rivers and borders being fixed and rigid. I argue that rivers are sites of uneven experiences not only in terms of access and use, but also in the way they are experienced as ‘borders’ by different communities, reflecting wider settler colonial dynamics and legacies. On the Yarmouk Tributary of the Jordan River, the river environments are borderised and territorialised in very unequal ways by nation‐states and through bilateral river basin agreements. Through paying attention to how river‐border environments have been transformed and how they function, this paper explores how the border is experienced and navigated in three border environments on the Yarmouk. This paper complicates the river‐as‐border scholarship by attending to how river borders are environments which are experienced differently by communities living in them through different forms of infrastructural and slow violence. Centring slow violence in this analysis offers a window into unexamined social worlds and experiences, showing how infrastructures on the border become environments and not just banal assemblages of pipes and pumps separate from people and land. It also presents an original contribution to examine transboundary river politics in the Jordan River Basin from the vantage points of the communities that continue to re‐configure ways to forge and mend relations with the river and border environments.

Background and purposeAtherosclerosis is the basis of cardiovascular disease. Ferroptosis is a form of programmed cell death characterized by lipid peroxidation, which contributes to atherogenesis. The plant extract PNS (Panax notoginseng saponins), containing the main active ingredients of Panax notoginseng, exhibits anti‐atherogenic properties. Herein, we determined whether PNS and its major components could attenuate atherosclerosis by suppressing ferroptosis and revealed the underlying mechanism(s).Experimental approachThe anti‐atherogenic effects of PNS and their association with inhibition of ferroptosis was determined in apoE−/− mice. In vitro, the anti‐ferroptotic effect and mechanism(s) of PNS components were demonstrated in the presence of ferroptosis inducers. Expression of ferroptosis markers and the ubiquitination of Keap1 were evaluated in USP2−/− macrophages. Finally, the anti‐atherogenic effect of USP2 knockout was determined by using USP2−/− mice treated with high‐fat diet (HFD) and AAV‐PCSK9.Key resultsPNS inhibited ferroptosis and atherosclerosis in vivo. PNS suppressed ferroptosis and ferroptosis‐aggravated foam cell formation and inflammation in vitro. Mechanistically, PNS and its components activated Nrf2 by antagonizing Keap1, which was attributed to the inhibition of USP2 expression. USP2 knockout antagonized ferroptosis and ferroptosis‐aggravated foam cell formation and inflammation, thus mitigating atherosclerosis. USP2 knockout abolished inhibitory effects of PNS on foam cell formation and inflammation in vitro.Conclusion and implicationsPNS reduced USP2‐mediated Keap1 de‐ubiquitination and promoted Keap1 degradation, thereby activating Nrf2, improving iron metabolism and reducing lipid peroxidation, thus contributing to an anti‐atherosclerotic outcome. Our study revealed the mechanism(s) underlying inhibition of ferroptosis and atherosclerosis by PNS.
