Material extrusion of TPU: thermal characterization and effects of infill and extrusion temperature on voids, tensile strength and compressive properties
Authors: Sardinha Manuel , Ferreira Luís , Diogo Hermínio , Ramos Tânia R.P. , Reis Luís , Vaz M. Fátima 
Published: January 2025

Purpose
This study aims to investigate the tensile strength and compressive behaviour of two thermoplastic polyurethane (TPU) filaments produced via material extrusion (ME): TPU 95A and Reciflex (recycled).

Design/methodology/approach
Tensile strength and compressive behaviour are assessed. The influence of extrusion temperature and infill pattern on these properties is examined, supported by thermal characterization, surface morphology analyses and a comprehensive comparison with existing literature. An analytical method is presented for estimating the solid ratio of ME parts, using an ellipse model to describe the material bead geometry.

Findings
Reciflex is generally stiffer than TPU 95A in both tensile and compressive tests. Specimens loaded orthogonally in compression tests exhibited stiffer behaviour than those loaded parallelly, and higher tensile properties were typically observed when material beads were deposited parallel to the load direction. Unlike TPU 95A, Reciflex is sensitive to extrusion temperature variations.

Social implications
By comparing recycled and virgin TPU filaments, this research addresses waste management concerns and advocates for environmentally sustainable production practices in the broadly used filament/based ME technique.

Originality/value
This study provides an extensive comparison of computed values with existing literature, offering insights into how different materials may behave under similar processing conditions. Given ongoing challenges in controlling melt flow during extrusion, these results may offer insights for optimizing the production of ME parts made with thermoplastic elastomers.

Authors: Xu Cong , Loo Sandie 
Published: January 2025

PurposeThe purpose of this review is to examine the current state-of-the-art in artificial intelligence (AI) implementations within library settings across Southeast Asia.Design/methodology/approachThe study uses the AI Library Services Innovative Conceptual Framework (AI-LSICF) to evaluate the AI initiatives in Southeast Asian libraries. Sources include relevant libraries and association’s websites, mainstream newspapers across Southeast Asia, together with academic papers published between 2019 and 2024, with a focus solely on English-language literature.FindingsMost of the Southeast Asian libraries are in the decision and implementation stages in utilising AI technologies into library operations. It is evident that most of the libraries have made the decision to embrace AI techniques in the workplace and have started to implement the AI-enabled applications. Nevertheless, those implementations are not yet comprehensive and most of the projects are still in the trial stage. This suggests a unanimous decision concerning the use of AI in the libraries across the region has not been reached. Librarians may still face challenges and concerns in adopting AI, including resource constraints, application maintenance, staff reluctance, staff training, data security concerns and more.Research limitations/implicationsA limitation of this study is its focus on completed and published projects, due to limited access to ongoing or unpublished initiatives. Non-English publications were excluded which may have omitted relevant studies and insights from non-English-speaking countries.Practical implicationsThis paper seeks to address the gap by conducting a review of the current landscape of AI applications within libraries across Southeast Asia. Its aim to provide valuable insights for Southeast Asian libraries which seek to leverage AI advancements, ultimately supporting more user-centric and technologically adept library services.Originality/valueThe originality of this paper lies in its unique perspectives on library settings in Southeast Asia, showcasing successful projects while also pinpointing areas and countries in need of further development.
Unveiling the nexus between ESG performance, climate policy uncertainty and corporate innovation: evidence from textual analysis
Authors: Sahu Asis Kumar , Debata Byomakesh , Khanna Garima 
Published: January 2025

Purpose
This paper aims to examine the relationship between environmental, social and governance (ESG) performance and text-based corporate innovation based on a sample of India’s ESG-disclosed companies from financial year 2011–2012 to 2021–2022. Further, it endeavors to investigate the moderating role of heightened climate policy uncertainty (CPU) in this relationship.

Design/methodology/approach
To verify these hypotheses, the authors first construct a corporate innovation index for India using a sophisticated natural language processing model on each firm-year’s management discussion and analysis reports. Next, the authors use a panel fixed effects model to examine how ESG performance impacts corporate innovation and its moderating and mediating components.

Findings
Empirical evidence suggests higher ESG performance bolsters text-based corporate innovation. After addressing endogeneity issues with the system GMM estimator and two-stage least square IV, incorporating additional control variables and using alternative innovation measurement, the baseline results remain unchanged. Next, the authors find this link is mediated by reducing information asymmetry, financial constraints and managerial myopia. The authors also observe that increased CPU favorably moderates the ESG-innovation nexus. Additionally, the heterogeneity research shows that ESG only positively impacts innovation in specific industries and firms in their growth and mature life cycle phases.

Practical implications
The results demonstrate that sustainable and ethical business practices can foster corporate innovation. Thus, this study may provide valuable insight for investors, managers and policymakers.

Originality/value
To the best of the authors’ knowledge, this is the first study to examine the relationship between ESG performance and text-based corporate innovation using a machine learning model.

Published: January 2025

AbstractIntroductionMild cognitive impairment (MCI) and Alzheimer's disease (AD) lead to decline in performance in activities of daily living (ADLs). Multiple questionnaires assess this construct among older adults. The objective of this study was to review existing literature studying psychometric properties of questionnaires assessing performance in ADLs of older adults living with MCI and AD specifically.MethodsA systematic review was conducted across Medline, CINAHL and PsychINFO using a combination of keywords related to ADLs, psychometrics, MCI and AD. Studies were included if they met the following criteria: assessments of performance of ADLs for older adults living with AD or MCI, reporting a minimum of one measurement property (e.g. internal consistency), primary research articles, published before June 2023 in English or French. Data extraction and analysis were conducted by two researchers. The methodological quality of psychometric properties was assessed using the COSMIN checklist.Consumer and Community InvolvementNo consumer or community involvement occurred.ResultsA total of 2539 articles were screened and filtered down to 50 articles including 24 questionnaires respecting inclusion criteria. Of these questionnaires, the three most validated were the Amsterdam Instrumental activities of daily living, the disability assessment for dementia (DAD), and the Bayer ADL scale. Overall, for these three questionnaires, internal consistency, reliability and structural validity were the most studied psychometric properties while criterion validity and hypothesis testing were the least.ConclusionThis study reveals the Amsterdam IADLs as the most validated questionnaire across psychometric properties and the DAD as the most validated across languages. Considering the increasing prevalence of older adults with MCI or AD, questionnaires established on strong measurement properties are valuable tools to evaluate decline in ADL performance and plan suitable interventions. This review provides evidence for clinicians and researchers for the selection of questionnaires to evaluate this population.PLAIN LANGUAGE SUMMARYCognitive impairment affects memory and thinking. It makes tasks like dressing, bathing and eating harder. Health‐care workers use questionnaires to find out where someone struggles. This helps them plan better care. We reviewed questionnaires for older adults with memory and thinking problems. We found good ones that give important information. Using these questionnaires helps health‐care workers support people with daily tasks. This study suggests testing the questionnaires more to improve them.

ABSTRACTSterol composition plays a crucial role in determining the ability of yeast cells to withstand high temperatures, an essential trait in biotechnology. Using a targeted evolution strategy involving fluconazole (FCNZ), an inhibitor of the sterol biosynthesis pathway, and the immunosuppressant FK506, we aimed to enhance thermotolerance in an industrial baker's yeast population by modifying their sterol composition. This approach yielded six isolates capable of proliferating in liquid YPD with μmax values ranging from 0.072 to 0.236 h−1 at 41.5°C, a temperature that completely inhibits the growth of the parental strain. The clones were categorised into two groups based on their respiratory competence or deficiency, the latter associated with mtDNA loss, an event seemingly linked to FCNZ and heat tolerance. Genome sequencing and ploidy‐level analysis of all strains revealed aneuploidies, copy number variations (CNVs), and single nucleotide polymorphisms (SNPs). Notably, all evolved clones exhibited specific point mutations in MPM1 (P50S) and PDR1 (F749S). CRISPR‐Cas9 experiments confirmed the role of the pdr1F749S mutation in the FCNZ‐tolerance phenotype and demonstrated that Mpm1 is required for growth at high temperatures. However, no apparent heat tolerance benefit was observed from single or combined mutations in these genes, supporting the hypothesis that thermotolerance is mediated by multiple interacting mechanisms. In this context, all evolved clones exhibited altered sterol profiles, with differences observed between respiratory‐competent and ‐deficient strains. In conclusion, our experimental evolution generated thermotolerant and fully competent strains and identified factors that could influence fluconazole and heat growth.

Published: January 2025

ABSTRACTUnderstanding is limited regarding strategies for addressing missing value when developing and validating models to predict cardiovascular disease (CVD) in type 2 diabetes mellitus (T2DM). This study aimed to investigate the presence of and approaches to missing data in these prediction models. The MEDLINE electronic database was systematically searched for English‐language studies from inception to June 30, 2024. The percentages of missing values, missingness mechanisms, and missing data handling strategies in the included studies were extracted and summarized. This study included 51 articles published between 2001 and 2024, involving 19 studies that focused solely on prediction model development, and 16 and 16 studies that incorporated internal and external validation, respectively. Most articles reported missing data in the development (n = 40/51) and external validation (n = 12/16) stages. Furthermore, the missing data were addressed in 74.5% of development studies and 68.8% of validation studies. Imputation emerged as the predominant method employed for both development (27/40) and validation (7/12) purposes, followed by deletion (17/40 and 4/12, respectively). During the model development phase, the number of studies reported missing data increased from 9 out of 15 before 2016 to 31 out of 36 in 2016 and subsequent years. Although missing values have received much attention in CVD risk prediction models in patients with T2DM, most studies lack adequate reporting on the methodologies used for addressing the missing data. Enhancing the quality assurance of prediction models necessitates heightened clarity and the utilization of suitable methodologies to handle missing data effectively.
What matters to mothers: A qualitative exploration of pain and recovery after cesarean section
Authors: Duch Patricia , Ekelund Kim , Nedergaard Helene Korvenius 
Published: January 2025

AbstractBackgroundFast recovery after cesarean section is vital since the mother not only has to take care of herself but also the newborn. Recovery scores are useful tools to measure and compare recovery; however, standardized questionnaires may miss in‐depth patient experiences. What is important to women in the postoperative period after cesarean section can vary in different populations, making it crucial to understand the specific needs of one's own population. This study aims to explore what matters most to Danish mothers during the early phase of recovery following elective cesarean section.MethodsQualitative design: Adult, Danish‐speaking women undergoing elective cesarean section under spinal anesthesia were included in three Danish hospitals. Semi‐structured interviews focusing on women's experiences of recovery, pain, and mobilization both in hospital and after discharge were conducted for 4–7 days following their cesarean section. Baseline characteristics and maternal outcomes were collected from patient files. The interviews were recorded, transcribed verbatim, and analyzed using manifest content analysis.ResultsIn total, 25 women were interviewed a median of 6 days post cesarean section (IQR 5–8). Three themes emerged: “Experience of being a cesarean section patient,” “I'm doing good – and better than expected,” and “Challenges when going home.” The cesarean section itself was described as a disturbing experience. The initial days post‐cesarean section were described as very painful, but hereafter, many patients expressed surprise at their rapid recovery. None used opioids after discharge. Post‐discharge, having a partner's support, especially with other children to care for, was helpful, and moving from lying to sitting position and getting out of bed were noted as particularly painful. Many women requested more information and specific rehabilitation programs.ConclusionsIn this qualitative study of Danish women 4–7 days after elective cesarean sections, the women described the initial days as very painful but felt that they recovered rather quickly thereafter. The study indicated a need for enhanced communication, especially regarding the experience of surgery, pain after cesarean section, and physical rehabilitation plans.Editorial CommentIn this qualitative, explorative study, participants were interviewed by telephone 4–7 days following their elective cesarean section. The focus was the women's experience of recovery, pain, and mobilization, both in hospital and when going home. The findings identified a need for more information about the perioperative course, as most participants were surprised and unprepared both for the pain from other areas than the scar and for the surgery experience being unpleasant, and many requested physical rehabilitation plans.

Published: January 2025

AbstractThe nematode C. elegans has long served as a gold‐standard model organism in aging research, particularly since the discovery of long‐lived mutants in conserved aging pathways including daf‐2 (IGF1) and age‐1 (PI3K). Its short lifespan and small size make it highly suitable for high‐throughput experiments. While numerous molecules have been tested for their effects on C. elegans lifespan, consensus is still lacking regarding the most effective and reproducible compounds. Confounding effects, especially those related to drug‐bacteria interactions, remain a contentious issue in the literature. In this study, we evaluated 16 of the most frequently reported lifespan‐extending molecules in C. elegans, examining their effects on lifespan with two different diets (live and UV‐killed OP50). In addition, we assessed the compounds' impact on bacterial growth, their effects on various nematode strains, and the impact of the starting age of treatment. Our findings first confirmed robust lifespan extension by many, but not all, of the 16 tested compounds from the literature, and revealed that some of them could be combined to obtain additive effects. Additionally, we showed that some of these compounds also extend lifespan in the fly D. melanogaster, demonstrating a conserved effect across species. Finally, by expanding our screen to a broader pool of molecules, we identified novel lifespan‐extending compounds in C. elegans.
Is a creative leader always helpful? A dependency perspective on the relationship between leader creativity and follower creativity
Authors: Zhao Kai , Lin Yuying , Yang Baiyin 
Published: January 2025

AbstractPrior studies draw on social learning theory to argue a positive relationship between leader creativity and follower creativity, lending support to the directing approach of leading for creativity. However, our study aims to provide a more comprehensive understanding for this approach by also exploring the negative effects of leader creativity on follower creativity, particularly from a dependency perspective. We investigated the mechanisms and boundary conditions by examining the roles of dependency on the leader, creative effort, and team power distance. With a sample of 136 leaders and 691 followers across four firms in China, we tested our hypotheses using multilevel path analyses. Our findings indicated that leader creativity was positively associated with followers' dependency on leader, and that dependency on leader had a negative indirect relationship with follower creativity via reducing follower creative effort. Overall, leader creativity had a negative indirect relationship with follower creativity through the pathways of increased dependency and decreased creative effort. Furthermore, the negative serial indirect relationship was more pronounced in teams with higher power distance. The theoretical and practical implications were discussed as well.

Published: January 2025

AbstractBackgroundThe purported reciprocity between motivation and academic achievement in education has largely been supported by correlational data.AimsOur first aim was to determine experimentally whether motivation and achievement are reciprocally related. The second objective was to investigate a potential behavioural mediation pathway between motivation and achievement by measuring the objective effort expended on learning. Finally, we studied the causality of these relations by analysing the dynamics between motivation and achievement (rather than examining them as individual constructs) when perceived achievement was experimentally manipulated.Sample(s)The study employed a short‐timeframe experiment in which 309 Dutch undergraduate students (Mage = 19.89, SD = 2.08) learned new English vocabulary.MethodsTheir motivation, effort, and achievement were measured at multiple time points within one hour. Midway through the experiment, participants received manipulated feedback indicating an achievement decline, which was expected to influence their subsequent motivation, effort, and actual achievement. A random‐intercept cross‐lagged panel framework was employed to model how one construct influenced another over time.ResultsWe found a unilateral effect of achievement on motivation (i.e., no reciprocity), which remained stable across the time points. Our experimental manipulation partially supported a causal interpretation of the unilateral achievement→motivation pathway. Additionally, no mediation effect of effort was identified: motivation was not associated with effort, nor was effort linked to achievement.ConclusionsOur findings underscore the importance of further exploration of behavioural mediation pathways, a broad operationalization of motivation, and the application of appropriate modelling strategies to investigate the motivation‐achievement reciprocity.
Metabolism‐lipid droplet‐nucleic acid crosstalk to regulate lipid storage and other cellular processes in oleaginous Rhodococcus bacteria
Authors: Alvarez Héctor M. , Lanfranconi Mariana P. , Hernández Martín A. 
Published: January 2025

AbstractActinobacteria belonging to Mycobacterium and Rhodococcus genera are able to synthesize and intracellularly accumulate variable amounts of triacylglycerols (TAG) in the form of lipid droplets (LDs). The lipid storage capacity of LDs in cells is controlled by the balance between lipogenesis and lipolysis. The growth of LDs in bacterial cells may be directly promoted by TAG biosynthesis, whereas TAG degradation might result in the reduction of LD sizes and lipid storage capacity. Therefore, LD formation and turnover have to be precisely regulated to maintain a balanced lipid distribution, coupling gene regulation with the metabolic state of the cell. In eukaryotic cells, LDs have emerged as critical mediators of diverse cellular responses, including fatty acid trafficking and modulation of transcriptional programs. Recent studies performed in mycobacteria and rhodococci suggested the existence of similar crosstalk mechanisms between lipid metabolism, LDs, and gene expression regulation in cells. This review connects and organizes results of different studies in a comprehensive framework for providing evidence of “lipid metabolism‐LDs‐genomic DNA” crosstalk occurring in TAG‐accumulating actinobacteria. We provide examples indicating that bacterial cells evolved sensing mechanisms that detect lipid metabolites changes as indicators of metabolic states, and adapt their transcriptional profiles through epigenetic‐like mechanisms mediated by LD‐associated proteins. Here, we describe the molecular interconnections of this coupling system and the main role of each component that integrates the information about the cellular metabolic state into the regulation of lipogenesis, LD formation and transcription in oleaginous bacteria.
