Dynamics modeling and simulation analysis of wet clutch considering spline pair
Authors: Niu Yinkai , Bao Heyun , Huang Wei , Tan Wuzhong , Zhu Rupeng 
Published: August 2023

Purpose
During the operation of a wet clutch, there are fluctuations in speed and torque, which have an impact on the stability of the clutch and the strength of the friction plate and the spline pair of the dual steel plate. The purpose of this study is to investigate the vibration characteristics of the wet clutch and the dynamic load characteristics of the spline pairs.

Design/methodology/approach
The spline pair model is established by the piecewise linear function method, and on this basis, dynamic equations considering the spline pair of dual steel plates and friction plates are established. Considering that the wet clutch has multiple spline pairs, an equivalent model of the number of teeth and the equivalent model of the tooth width were proposed, and the Runge-Kutta numerical method was used for the wet clutch for these two models.

Findings
The research results show that the equal tooth number model has greater meshing stiffness and smaller fluctuation than the constant tooth width model, which shows that increasing the meshing stiffness of the system is beneficial to reduce system fluctuation and improve system stability.

Research limitations/implications
The friction plate has the system that multiple splines are independent of each other, which is relatively complicated. Therefore, an equivalent calculation is performed on multiple pairs of steel plates (friction plates) to simplify the calculation of the spline pairs.

Social implications
This paper provides a theoretical basis for further dynamic characteristics analysis of wet clutch and reducing fluctuation of speed and torque.

Originality/value
Dynamic equation considering the spline pair of the dual steel plates and the friction plates is established to study the vibration characteristics of the wet clutch and the dynamic load characteristics of the spline pair, etc.

Are returns from adoption of soil conservation practices heterogeneous? Evidence from Indian agriculture
Authors: Akber Nusrat , Paltasingh Kirtti Ranjan 
Published: August 2023

PurposeThis paper finds the returns from soil conservation practices and examines whether the welfare implications of adopting the conservation practices are heterogeneous across the farming groups in Indian agriculture.Design/methodology/approachThe study uses an endogenous switching regression (ESR) method on the data collected from the 77th round of National Sample Survey (2019–21) to quantify the returns from adopting soil conservation practices.FindingsIt finds that farmers adopting soil health conservation practices would have reduced their crop yield by 13% if they did not implement them. Similarly, smallholders who have not adopted soil health management practices would have increased crop yield by 16% if they had adopted the practices. The authors also observed that the returns from adopting soil health management practices vary across farming groups, where marginal and large farms tend to gain higher yields. Finally, the authors find that regardless of farm size, smallholders who did not adopt soil health management practices would benefit from adopting these with increased crop yields of 29%–31%.Research limitations/implicationsMore data could have been better for drawing policy implications, since the number of soil card users are relatively less.Originality/valueThis research work uses nationally representative data, which is first in nature on this very aspect.

Authors: Rodriguez Anita G. , Madadi Rozbeh , Blaugrund Erin Baca , Acharya Ram N. , Idowu O. John , Zúñiga Miguel Ángel , Torres Ivonne M. 
Published: August 2023

Purpose
The purpose of this study is to investigate genetically modified food labeling effects on dietary restrained consumers’ perception and purchase intention based upon various labels and food type – whole versus processed.

Design/methodology/approach
A 2 (food type: whole vs processed) × 2 (product label: genetically modified organism [GMO] vs nongenetically modified organism [non-GMO]) research design was used in two steps. In the first step, the authors distributed 1,000 surveys, of which 858 surveys were used, and in the second step, the authors distributed 1,000 surveys and were able to use 891 surveys.

Findings
Results show that respondents with higher levels of dietary restraint have higher levels of perceived healthfulness. In addition, respondents with higher perceived healthfulness levels have a higher level of purchase intention for whole/GMO products, whole/non-GMO products, processed/GMO products and processed/non-GMO products. Moreover, the results show that individuals have higher purchase intention for whole/non-GMO than the whole/GMO products, whole/GMO than the processed/non-GMO products and processed/non-GMO than the processed/GMO products.

Research limitations/implications
A future longitudinal study with assigned tracking numbers is suggested. Given that four different blocks were randomized, comparing data among individual participants would be interesting, as the ability to compare responses would be feasible among the four separate blocks.

Originality/value
The results of this study may assist the government in policy development, food manufacturers in labeling techniques used and consumers by increasing transparency and information availability.
Green product consumption behaviour, green economic growth and sustainable development: unveiling the main determinants
Authors: Armutcu Barış , Zuferi Rasim , Tan Ahmet 
Published: August 2023

Purpose
The purpose of the current study is to help remove the obstacles to sustainable production and consumption by revealing the determinants of green consumption behaviour, which is one of the precursors of sustainable economic growth. This study aims to expand the theory of planned behaviour (TPB) model and contribute to the relevant literature by investigating the factors of social media usage, social media marketing and digital marketing interactions that have not been investigated before in relation to green product purchasing behaviour.

Design/methodology/approach
This study examines the effect of the extended TPB model on consumers’ intention to buy green products in Turkey, which has a Middle Eastern culture and is a developing economy. In the study, data collected from 409 participants with the questionnaire method were analysed using SmartPLS 4.0 and IBM SPSS 26 statistical programs.

Findings
The study findings revealed that all the structural elements of TPB (attitude, subjective norms, personal behaviour controls) and social media marketing and digital marketing interactions contribute to consumers’ green product purchasing behaviour. The study findings also demonstrated that the use of social media is not effective in the purchasing of green products.

Originality/value
Understanding consumers’ perspective on purchasing green products is crucial for policymakers, businesses and marketers, as it helps formulate appropriate strategies to support sustainable economic growth. In this respect, this study has important implications for sustainable consumption and production. In addition, to the best of the authors’ knowledge, the study is the first to examine consumers’ green product purchasing behaviour in the context of sustainable economy.
Entrepreneurial opportunities and difficulties under COVID-19 for women entrepreneurs in Asia and Europe
Authors: Sörensson Anna , Ghannad Navid 
Published: August 2023

Purpose
The purpose of this study is to explore and gain a greater understanding of women's entrepreneurship during the COVID-19 pandemic. How have women entrepreneurs changed their entrepreneurship during the COVID-19 pandemic? What dimensions are highlighted by women entrepreneurs for a sustainable entrepreneurship during the COVID-19 pandemic?

Design/methodology/approach
This study was conducted with a qualitative design where multiple case studies were conducted with 30 women. Data were collected through qualitative interviews with the women entrepreneurs in Asia and Europe.

Findings
The results from this study show that women entrepreneurs have mainly focused on financial resources. Economic sustainability is required for companies to survive a crisis in the form of a pandemic. This study has shown what lessons women have from the pandemic where the four D’s model constitute a first step to a theoretical contribution. For women, it is about dollars (e g economic sustainability), demand from customers, the role that digitization has played and distribution both to customers and from suppliers.

Practical implications
Practical implications from this study are that women entrepreneurs need to be prepared for economic crises to a larger extent. The economic sustainability plays a key role in sustainable businesses for women entrepreneurs in any kind of context.

Social implications
Women's entrepreneurship looks different, and more knowledge is needed about their conditions. It contributes to increased social sustainability.

Originality/value
This study contributes to an increased understanding of how women's entrepreneurship has been affected during a global crisis.
Responsibilization during uncontrollable events: understanding how consumers assign and accept responsibility for service employee welfare
Authors: Moran Nora , Shepherd Steven , Alvarado Janice 
Published: August 2023

Purpose
The purpose of this paper is to study how individuals assess responsibility during an uncontrollable event requiring collective action, using crises affecting service workers as contexts. Specifically, the authors examine what parties consumers hold responsible for ensuring service worker welfare following an uncontrollable event and determine what factors make customers more open to accepting responsibility for ensuring worker welfare themselves.

Design/methodology/approach
The authors surveyed a nationally representative sample of US consumers regarding their attitudes toward protecting service workers during COVID-19 and used regression analysis to identify factors that predict attributions of responsibility to customers. The authors also conducted an experiment (using a new crisis context) to determine whether certain key factors impact customer perceptions of their own responsibility for helping employees during an uncontrollable event.

Findings
The survey results show US consumers hold firms most responsible for worker welfare, followed by customers and, finally, government. When examining factors that drive attributions of responsibility for customers, perceptions of how sincere firms are in their efforts to help employees predict higher responsibility attributions, and experimental results confirm that higher perceived firm sincerity increases consumers’ own sense of responsibility toward workers.

Social implications
This research identifies factors that affect consumer support for efforts to help service employees and collective action problems more generally.

Originality/value
This research highlights an under-studied crisis context – uncontrollable events that require collective action – and shows how consumers make assessments about their own responsibility (in addition to the responsibility of the service firm) in these contexts.
Breviscapine reverses doxorubicin resistance in breast cancer and its related mechanisms
Authors: Fu Weijiang , Song Jie , Li Haiying 
Published: August 2023

AbstractBackgroundBased on the effect of breviscapine (BRE) on reversing drug resistance of human breast cancer cell line MCF‐7/doxorubicin (Dox), the mechanism was preliminarily explored.MethodsThe methyl thiazolyl tetrazolium (MTT) method was introduced to detect inhibitory effect of Dox alone or in combination with BRE on MCF‐7 (M) and MCF‐7/Dox (MD) cells, and the inhibitory concentration (IC50) was obtained. Cell apoptosis and Dox concentration was assessed by flow cytometry. The drug resistance multiple and reversal fold were calculated. Western blot was performed to evaluate the expression of Bcl‐2, Bax, EGFR, p‐EGFR, P‐gp, caspase‐3, and cleaved‐caspase‐3 protein in cells. The efflux of Rho‐123 was measured by flow cytometry and fluorescence microscopy.ResultsThe IC50 of Dox on MD and M cells was 16.67 and 0.71 μg/mL, respectively, with a drug resistance ratio of 23.48 times. The IC50 of Dox combined with BRE on MD cells was 5.62 μg/mL, with a reversal ratio of 2.97 times. BRE greatly enhanced Dox‐induced apoptosis of MD cells. Bax and cleaved‐caspase‐3 (proapoptotic protein) expression were obviously increased, while Bcl‐2 (antiapoptotic protein) expression was significantly decreased after BRE treatment. BRE inhibited EGFR activation and P‐gp expression. BRE increased the intracellular accumulation of Dox in MD cells by P‐gp.ConclusionBRE could increase the MD sensitivity to Dox via increasing Bax and cleaved‐caspase‐3 expression and inhibiting Bcl‐2 expression, thereby promoting cell apoptosis. BRE reversed Dox resistance of MD cells by increasing Dox intracellular accumulation through inhibiting P‐gp expression via EGFR.
The importance of audit partners' risk tolerance to audit quality
Authors: Pittman Jeffrey , Stein Sarah E. , Valentine Delia F. 
Published: August 2023

AbstractRelying on their history of legal infractions to measure individuals' risk tolerance, we examine the association between engagement partners' risk appetites and audit quality in the United States. Criminology and economics research links infraction activity with enduring personality traits that capture an individual's risk tolerance. Our evidence supports the prediction that partners known to engage in risky off‐the‐job behaviors conduct lower quality audits. Specifically, we find that clients of partners with prior legal infractions exhibit a higher likelihood of material misstatements revealed through subsequent restatements, greater propensity to misstate based on the F‐score, more instances of “missed” material weaknesses, and less timely loss recognition, while also paying lower audit fees. In cross‐sectional results consistent with expectations, we generally find that the impact of partners' risk tolerance on audit quality is more heavily concentrated in clients of non–Big 4 firms and offices without industry expertise. Collectively, our analysis contributes to emerging research on the role that individual partner characteristics play in shaping audit outcomes.
Care coordination for children with a disability or developmental difficulty: Empowers families and reduces the burden on staff supporting them
Authors: Myers Sarah , Collins Bethan , Maguire Sabine 
Published: August 2023

AbstractBackgroundAlmost half of all children and young people with a disability or developmental difficulty (DDD) have complex disability and are likely to require multidisciplinary care. Care coordination (CC) aims to provide a single point of contact and a coordinated service, thereby improving care experiences, meeting unmet needs and empowering families. The impact of CC for children with DDD was evaluated.MethodBetween May and August 2020, an in‐depth evaluation of CC in Gwent, South Wales was conducted. Of 284 families who accessed CC, 38 were approached, as well as 177 health and social care professionals based at Serennu, Nevill Hall and Caerphilly Children's Centres. Nine families and 14 professionals completed semi‐structured interviews. Interview transcripts were analysed using thematic analysis.ResultsThis evaluation found perceived improvements in families' abilities to navigate, organize and understand care and increased parental engagement. Professionals observed fewer missed appointments, and both professionals and families described CC as a source of holistic support, including practical advice regarding housing, finances and emotional support. Professionals commented on CC easing pressure on their service. Potential limitations included restricted staff capacity and the role not being defined clearly for families and professionals.ConclusionsAt a time of increased stress for families of children with DDD, and scarce resources to support them, care coordinators play a vital role in assisting families to engage with health services, while feeling supported and empowered. CC reduces the burden on professionals, while enhancing relationships with families.

Published: August 2023

AbstractInterim analysis of the National Skin Centre Singapore Psoriasis Biologics Registry (SINGPSOR) from August 2017 to May 2021, in which 58 patients were analysed, showing that those receiving biologic treatment had significantly more severe psoriasis based on PASI (Psoriasis Area and Severity Index), BSA (body surface area) and PGA (Physician Global Assessment) measures at baseline, demonstrated a statistically non‐significant trend towards greater improvement with treatment, and had a lower percentage of adverse events compared to those receiving conventional systemic therapy. Future analyses of SINGPSOR, with larger sample size and longer follow‐up, will be invaluable to further characterize these patients and their treatment outcomes.
Forever young: Relative age effects in Belgian political selection
Authors: Al Yussef Alan , Heyndels Bruno , Le Boulaire Pauline 
Published: August 2023

AbstractPolitical selection is crucial for the functioning of democracy. However, the practice—in education and sports contexts—of artificially dividing school‐age children into different age groups leads to a considerable bias in this selection. The probability of becoming a (successful) politician depends on individuals' relative age. Being born shortly after the cut‐off date significantly increases the probability that an individual will be politically successful later in life. Using a regression discontinuity design, we find strong evidence of such relative age effect (RAE) among a large sample of Belgian federal parliamentarians over the period 1950–2019 (N = 4032), but not among municipal councillors (N = 7387), nor among municipal candidates (N = 36,740) in the 2018 election. The estimated overrepresentation of federal members of the parliament (MPs) born immediately after the cut‐off date is up to 90% compared to politicians born just before the cut‐off date. The overrepresentation is observed over the whole period and thus seems to be deeply rooted in the political system. We find the RAE to have a gendered dimension: The effect is driven by early‐born male politicians' overrepresentation. No significant RAE was found among female politicians.
Linking stress to the emergence of relational turbulence in marriage
Authors: Brisini Kellie St. Cyr , Solomon Denise Haunani , Brinberg Miriam 
Published: August 2023

AbstractThe assumption that stress negatively impacts marital relationships is widely accepted; however, the majority of research has focused on marital satisfaction as the outcome of interest. Relational turbulence is a quality of romantic associations on par with—but distinct from—satisfaction, in which partners conceptualize their relationship as chaotic or tumultuous. This paper draws on relational turbulence theory (RTT) and stress spillover research to propose that day‐to‐day stress corresponds with perceptions of relational uncertainty and interdependence, which contributes to increases in relational turbulence. We evaluated these assumptions using data from 64 heterosexual married partners who experienced work‐related disruptions due to the COVID‐19 pandemic. Spouses completed a pre‐test survey, 10 weekly surveys, and a post‐test survey over 12 weeks from June to August 2020. Results from longitudinal actor‐partner interdependence models indicated that (a) wives' weekly stress corresponded positively with their own partner uncertainty, relationship uncertainty, and perceptions of partner interference, and (b) the magnitude of wives' stress spillover and husbands' change in relational turbulence were positively associated. Implications for RTT and research on stress spillover are discussed.

Published: August 2023

Abstract
This research presents a detailed transient experimental and computational study of heat transfer and airflow in a scaled room linked with a double-duct vertical roof solar chimney (SC). The analysis was made in the coupled system, varying the heat flux supplied to the roof SC absorber during the day. Experimental temperature profiles were obtained at six different depths and heights, the empirical heat transfer coefficient was computed for the SC absorber, and the variation of air changes per hour was determined. A good agreement between experimental and numerical temperature profiles and average Nusselt number (Nut) is shown in the latter of average difference of 3.41%. The validated computational model was used to analyze the effect of the transient heating of the SC on temperature fields and flow patterns in the thermal system. Almost symmetrical temperature and y-velocity profiles are formed in the ducts at different hours of the day, with thermal boundary layers of about 4 mm. Correlations of the Nusselt number and air changes per hour (ACH) are provided as a function of the modified Rayleigh number.
Effect of Dehydroxylation on Tribological Performances of Synthetic Magnesium Silicate Hydroxide as Lubricant Additive
Authors: Zhang Hao , Zhang Chenhui 
Published: August 2023

Abstract
The heat-treated nanoparticle heat-treated magnesium silicate hydroxide (MSHH) was obtained based on the synthesis of lamellar nanoparticle magnesium silicate hydroxide (MSH) and analysis of thermal stability, and the morphology, phase composition, and chemical groups of nanoparticles were subsequently characterized. The heat treatment process induces partial dehydroxylation of MSHH, while preserving the layered structure. Compared with MSH, the tribological performances of MSHH as a lubricant additive have been greatly improved. The mechanical properties of MSH and MSHH are analyzed by calculation of elastic constants using density functional theory (DFT). The interactions among dispersant oleic acid (OA), nanoparticles (MSH and MSHH), and Fe tribopairs were investigated by simulations of classical molecular dynamics (CMD) from the views of adsorption energy and confined shear. The tribological mechanism of MSHH as a lubricant additive is proposed based on the decreased shear strength and weakened agglomeration.
