Authors: Zhang Aixin , Deng Wenli , Li Qiuyang , Song Zilong , Ke Guizhen 
Published: August 2024

Purpose
This paper aims to demonstrate that, in line with the emerging trend of multifunctional yarn development, cotton yarn can effectively harness renewable solar energy to achieve photothermal conversion and thermochromism. This innovation not only maintains the comfort associated with natural fiber cotton yarn but also enhances its ultraviolet (UV) light resistance.

Design/methodology/approach
In this work, 4% zirconium carbide (ZrC) and thermochromic powder were adhered to cotton yarn through polyurethane (PU) by sizing coating method. After sizing, the two cotton yarns are twisted by ring spinning to obtain composite yarns with photothermal conversion and thermochromic functions.

Findings
The yarn obtained by cotton/6%PU/8% thermochromic dye single yarn and cotton/6%PU/4% ZrC single yarn composite is the best match. After 5 min of infrared light, the temperature of the composite yarn rose to the maximum, increasing by 36.1°C. The ΔE* value before and after irradiation of infrared lamp is 26.565, which proves that the thermochromic function is good. The yarn dryness unevenness was significantly reduced by 27.2%. The composite yarn has a UPF value of up to 89.22, and its performance characteristics remain stable after 100 minutes of washing.

Originality/value
The composite yarn’s photothermal conversion and thermochromism functions are mutually reinforcing. Using sunlight can simultaneously achieve heating and discoloration effects without consuming additional energy. The cotton yarn used in this application is versatile, and suitable for a wide range of uses including clothing, temperature visualization detection and other scenarios.
Beyond formality: a bricolage model to navigate between the conflicting considerations in social impact assessments
Authors: Helleputte Coralie , Périlleux Anaïs 
Published: August 2024

Purpose
Social enterprises (SEs) are increasingly expected to rely on formal methodologies to assess their social impact. These structured methodologies, which produce objective and evidence-based measures of impact, are sometimes opposed to bricolage approaches that “make do” with what is at hand. This paper aims to question this distinction by identifying the conflicting considerations that arise in the process of implementing a formal methodology, which might lead SEs to rely on bricolage mechanisms. The authors propose a model of “formally-driven” bricolage with core principles to navigate between those considerations.

Design/methodology/approach
Adopting an inductive approach, the authors draw on the in-depth case study of a work integration SE engaged in a formal social impact assessment (SIA) through collaborative research.

Findings
First, the authors identify five types of considerations (feasibility, efficiency, ethics, legitimacy and aim) that come into tension with the primary considerations of formality in formal methodologies, leading SEs to still rely on bricolage mechanisms. Second, the authors identify five principles (multidimensional, participative, cultural, mixed-method and adaptive) that permit navigation between those conflicting considerations. Based on the findings, the authors develop a model of “formally-driven” bricolage.

Originality/value
The contribution is methodological, theoretical and practical. The authors bridge the gap between theory and practice through long-term immersion in an SE. The authors contribute to the understanding of the use of bricolage in SIA by investigating why and how bricolage is still at play in formal assessments. The proposed model of “formally-driven” bricolage can help researchers and practitioners to better grasp the ins and outs of the SIA process.
The many socials: how a social enterprise uses social media to communicate social capital-based social value. A case study
Authors: Wang Qian , Hallin Anette , Lång Stefan , Barner-Rasmussen Wilhelm 
Published: August 2024

Purpose
This study responds to the need in social entrepreneurship research for more empirical studies to clarify the meaning of social value. Specially, it aims to explore the meaning of social value communicated on social media (SoMe) within the local context of a social enterprise (SE).

Design/methodology/approach
A multimodal social semiotic approach was applied to several hundred Facebook posts of a Finnish SE providing elderly care solutions, complemented by secondary data from high-quality press sources.

Findings
Building on Young’s (2006) dimensions of social value and Hidalgo et al.’s (2021) theorisation of social capital in social entrepreneurship, the authors find that an SE draws on multiple levels of social capital on SoMe to express the meaning of the social value it creates.

Research limitations/implications
Although limited to one case, this study provides a deep contextual understanding of how SEs can give meaning to social value and leverage social capital on SoMe to do so.

Practical implications
The authors offer a contextually embedded framework for SEs to communicate social value through media. This approach enables SEs to engage stakeholders more effectively and improve the quality of support for local initiatives.

Social implications
Improvements in SEs’ ability to communicate social value will increase their legitimacy, thus enhancing their prospects to survive and create sustained social value.

Originality/value
The authors strengthen the theoretical underpinnings of social value by being among the first to empirically describe its connection to social capital in an SE, thereby deepening previous studies on subjective social value. Methodologically, this study is the first, to the best of the authors’ knowledge, to apply social semiotics to research on SEs.
Tourism-led growth hypothesis (TLGH) in Africa: does institutional quality matter?
Authors: Chiriko Amare Yaekob , Alemu Sintayehu Hailu , Kim Seongseop (Sam) 
Published: August 2024

Purpose
While the tourism–growth nexus is one of the better researched themes in both tourism and economics literature, there is limited evidence on how institutional quality affects this link, especially in the context of the developing world. To address this gap, this study aims to investigate the tourism-led growth hypothesis (TLGH) through the lens of institutional quality, drawing on evidence from African economies.

Design/methodology/approach
This study adopts a longitudinal design, involving panel data on 43 countries over an 18-year period, and the data were analyzed using the difference generalized method of moments model.

Findings
Results indicated that international tourism earnings contributed to economic growth in the selected economies. However, institutional quality negatively moderated the tourism–growth relationship on the continent, particularly in low-income economies, while reinforcing this link in middle-income countries.

Originality/value
This study provides new insights into how the TLGH varies across different levels of institutional quality and development.
Leaf functional traits predict timing of nutrient resorption and carbon depletion in deciduous subarctic plants

Published: August 2024

Abstract

Resorption of key elements promotes their conservation in plants in nutrient‐poor ecosystems. In seasonal environments, the timing of resorption is expected to influence resorption efficiency and plant fitness due to the trade‐off between maximizing photosynthetic carbon gain by late resorption and minimizing frost risks and nutrient loss by early resorption. Here, we hypothesize that (1) these alternative strategies with respect to the timing of element resorption both occur among summergreen species; (2) deciduous woody plants favour delayed resorption while herbaceous species benefit from gradual, early onset resorption; (3) this pattern is part of a more general relationship in which species with conservative resource economic traits have more delayed resorption.

We measured nitrogen (N), phosphorus (P) and carbon (C) contents of mature, senescing and senesced leaves of 22 predominant plant species across four types of ecosystems in a subarctic region. We then calculated timing of resorption as the Julian calendar day of 50% of element resorption (T50), and examined its relationship with plant functional types and leaf resource economic traits (leaf mass per area [LMA], leaf C, N and P contents).

The timing of N resorption in subarctic plants ranged from day 213 to 254, while the timing of P resorption ranged from day 211 to 261 and of C from day 214 to 260 across species. On average, the resorption of N and P and depletion of C were 13, 12 and 19 days respectively earlier in herbaceous plants than in woody ones. For all the three elements, T50 of plants decreased significantly with increasing acquisitive economic traits.

Synthesis: As hypothesized, we found that (1) both “steady‐and‐slow” and “late‐and‐fast” strategies of resorption timing co‐occurred in a subarctic flora; consistent with these two strategies, herbaceous plants resorbed nutrients and carbon earlier than deciduous woody species; (2) relevant functional traits representing resource conservation were positively and linearly related to the timing of nutrient resorption and carbon depletion. These findings for element resorption timing have important implications for functional changes in the vegetation composition of seasonal regions in response to temperature fluctuations in a changing climate.

AbstractStudents with impairment whether physical, sensory or intellectual face challenges in their quest to have inclusive education predisposing them to various stressors. Yet, studies have rarely explored this important psychological construct. This cross‐sectional study assessed the prevalence of psychological distress and how perceived social support and academic resilience predict distress in this population. A total of 101 students with hearing, visual and physical impairments were purposively sampled and administered questionnaires that measured psychological distress, social support and academic resilience. Results revealed the prevalence of psychological distress was 75.5%. Also, perceived social support (β = −0.25, p < 0.01) and academic resilience (β = −0.34, p < 0.001) significantly predicted psychological distress with perseverance (β = −0.51, p < 0.001) being the only dimension of academic resilience that predicted psychological distress. This study concludes that students with impairments have a high prevalence of psychological distress, which can be reduced through social support and resilience building interventions at both individual and group levels. We recommend that these counselling interventions be provided for students with impairment to help them deal with the challenges or stressors they encounter.
Effect of cruciferous vegetable intake on cancer: An umbrella review of meta‐analysis

Published: August 2024

AbstractPrevious systematic evaluations and meta‐analyses of the relationship between cruciferous vegetable (CV) intake and cancer risk have yielded inconsistent results. Herein, we summarize and evaluate the existing data and examine the relationship between CV intake and cancer risk. We searched four databases for cancer risk as a key outcome indicator. AMSTAR‐2 was used to evaluate the methodological quality of the included systematic reviews, PRISMA 2020 was used to evaluate the report quality, and corrected coverage area analysis was used to evaluate the duplication rate of the original documents. Overall, 22 meta‐analyses involving 175 independent cancer studies were included. Evidence on lung, gastric, prostate, breast, endometrial, and ovarian cancer, as well as renal cell carcinoma, suggests a potential association between cancer and CV intake, which influences the risk of various cancers. Future research should focus on improving methods and techniques, controlling influencing factors, elucidating underlying mechanisms, and improving evidence quality to demonstrate the association between CV intake and cancer. The potential role of dietary CVs in cancer control has implications for public health policies.

AbstractNeuronal cells are highly specialized cells and have a specific metabolic profile to support their function. It has been demonstrated that the metabolic profiles of different cells/tissues undergo significant reprogramming with advancing age, which has often been considered a contributing factor towards aging‐related diseases including Alzheimer's (AD) and Parkinson's (PD) diseases. However, it is unclear if the metabolic changes associated with normal aging predispose neurons to disease conditions or a distinct set of metabolic alterations happen in neurons in AD or PD which might contribute to disease pathologies. To decipher the changes in neuronal metabolism with age, in AD, or in PD, we performed high‐throughput steady‐state metabolite profiling on heads in wildtype Drosophila and in Drosophila models relevant to AD and PD. Intriguingly, we found that the spectrum of affected metabolic pathways is dramatically different between normal aging, Tau, or Synuclein overexpressing neurons. Genetic targeting of the purine and glutamate metabolism pathways, which were dysregulated in both old age and disease conditions partially rescued the neurodegenerative phenotype associated with the overexpression of wildtype and mutant tau. Our findings support a “two‐hit model” to explain the pathological manifestations associated with AD where both aging‐ and Tau/Synuclein‐ driven metabolic reprogramming events cooperate with each other, and targeting both could be a potent therapeutic strategy.

AbstractWhite adipose tissue (WAT) is a robust energy storage and endocrine organ critical for maintaining metabolic health as we age. Our aim was to identify cell‐specific transcriptional aberrations that occur in WAT with aging. We leveraged full‐length snRNA‐Seq and histology to characterize the cellular landscape of human abdominal subcutaneous WAT in a prospective cohort of 10 younger (≤30 years) and 10 older individuals (≥65 years) balanced for sex and body mass index (BMI). The older group had greater cholesterol, very‐low‐density lipoprotein, triglycerides, thyroid stimulating hormone, and aspartate transaminase compared to the younger group (p < 0.05). We highlight that aging WAT is associated with adipocyte hypertrophy, increased proportions of lipid‐associated macrophages and mast cells, an upregulation of immune responses linked to fibrosis in pre‐adipocyte, adipocyte, and vascular populations, and highlight CXCL14 as a biomarker of these processes. We show that older WAT has elevated levels of senescence marker p16 in adipocytes and identify the adipocyte subpopulation driving this senescence profile. We confirm that these transcriptional and phenotypical changes occur without overt fibrosis and in older individuals that have comparable WAT insulin sensitivity to the younger individuals.

Published: August 2024

AbstractIntroductionThe aim of this systematic review is to assess the functional magnetic resonance imaging (fMRI) studies of bipolar disorder (BD) patients that characterize differences in terms of structural, functional, and effective connectivity between the patients with BD, patients with other psychiatric disorders and healthy controls as possible biomarkers for diagnosing the disorder using neuroimaging.MethodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA), guidelines a systematic search for recent (since 2015) original studies on connectivity in bipolar disorder was conducted in PUBMED and SCOPUS.ResultsA total of 60 studies were included in this systematic review: 20 of the structural connectivity, 33 of the functional connectivity, and only 7 of the studies focused on effective connectivity complied with the inclusion and exclusion criteria.DiscussionDespite the great heterogeneity in the findings, there are several trends that emerge. In structural connectivity studies, the main abnormalities in bipolar disorder patients were in the frontal gyrus, anterior, as well as posterior cingulate cortex and differences in emotion and reward‐related networks. Cerebellum (vermis) to cerebrum functional connectivity was found to be the most common finding in BD. Moreover, prefrontal cortex and amygdala connectivity as part of the rich‐club hubs were often reported to be disrupted. The most common findings based on effective connectivity were alterations in salience network, default mode network and executive control network.Although more studies with larger sample sizes are needed to ascertain altered brain connectivity as diagnostic biomarker, there is a perspective that the method could be used as a single marker of diagnosis in the future, and the process of adoption could be accelerated by using approaches such as semiunsupervised machine learning.

AbstractThis study aimed to evaluate the antibiofilm activity of different concentrations of silver nanoparticles (AgNPs) in combination with calcium hydroxide [Ca(OH)2] against Enterococcus faecalis biofilm. On an E. faecalis biofilm on dentin discs, the following medicaments were applied for 7 days (n = 13/group): 0.005% AgNPs+Ca(OH)2, 0.01% AgNPs+Ca(OH)2, 0.02% AgNPs + Ca(OH)2, Ca(OH)2 and saline/control. Specimens were stained with LIVE/DEAD® BacLight™ dye and analysed with confocal laser scanning microscopy. Proportion of dead bacteria was calculated and analysed. There was a significant reduction in E. faecalis biofilm in all medicament groups (43.5%, 49.1%, 69.1%, 48.7%) respectively, compared with control group (2.54%) (p < 0.001). The 0.02% AgNPs + Ca(OH)2 group demonstrated the most significantly superior antibiofilm effect, with no significant difference between remaining groups. In conclusion, combining 0.02% AgNPs enhanced the antibiofilm effect of Ca(OH)2 on E. faecalis biofilm compared with lower AgNPs concentrations.

Published: August 2024

AbstractBackgroundThere is a long‐standing debate if finasteride, a medication used to treat benign prostatic hyperplasia (BPH) and androgenetic alopecia (AGA), can cause psychiatric side effects.ObjectiveThe goal of this large‐scale population‐based study was to determine whether finasteride therapy for BPH and AGA is associated with the emergence of mental health conditions.MethodsThis observational case–control study compared the data from patients with BPH who received finasteride 5 mg daily and patients with AGA who received finasteride 1 mg daily with age‐ and gender‐matched controls. The incidence of psychological health outcomes such as depression, anxiety, neuroses, bipolar disorder, schizophrenia, psychoses and alcohol abuse within 2 years of the initiation of finasteride therapy has been evaluated and compared between the finasteride groups and controls.ResultsThe BPH group included 307 men with a mean age of 61.5 (±17.4) years and 1218 controls. Mental health outcomes recorded in 2.3% of the patients, with no significant increase in rate when compared to controls. The AGA group consisted of 23,227 men with a mean age of 31.4 (±10.3) years and 39,444 controls. One percent of AGA patients developed psychiatric disorders. In comparison to controls, patients with AGA had higher rates of anxiety and depression (0.6% vs. 0.4%, p = 0.04, and 0.5% vs. 0.4%, p = 0.007, respectively). In multivariate regression models, finasteride was found as one of the risk factors for anxiety (OR 1.449, p = 0.002) and depression (OR 1.439, p = 0.003) when stratified to age, sector, socioeconomic status and comorbidities.ConclusionsAccording to our research, finasteride users had a very low rate of adverse mental health effects, with no increase in psychological sequelae in BPH patients and a slight increase in anxiety and depression in AGA patients.
