Published: November 2023

ABSTRACTThe metabolic networks of microorganisms are remarkably robust to genetic and environmental perturbations. This robustness stems from redundancies such as gene duplications, isoenzymes, alternative metabolic pathways, and also from non-enzymatic reactions. In the oxidative branch of the pentose-phosphate pathway (oxPPP), 6-phosphogluconolactone hydrolysis into 6-phosphogluconate is catalysed by 6-phosphogluconolactonase (Pgl) but in the absence of the latter, the oxPPP flux is thought to be maintained by spontaneous hydrolysis. However, in Δpgl Escherichia coli, an extracellular pathway can also contribute to pentose-phosphate synthesis. This raises question as to whether the intracellular non-enzymatic reaction can compensate for the absence of 6-phosphogluconolactonase and, ultimately, on the role of 6-phosphogluconolactonase in central metabolism. Our results validate that the bypass pathway is active in the absence of Pgl, specifically involving the extracellular spontaneous hydrolysis of gluconolactones to gluconate. Under these conditions, metabolic flux analysis reveals that this bypass pathway accounts for the entire flux into the oxPPP. This alternative metabolic route - partially extracellular - sustains the flux through the oxPPP necessary for cell growth, albeit at a reduced rate in the absence of Pgl. Importantly, these findings imply that intracellular non-enzymatic hydrolysis of 6-phosphogluconolactone does not compensate for the absence of Pgl. This underscores the crucial role of Pgl in ensuring the efficient functioning of the oxPPP.
Prediction of hot corrosion behavior of Inconel 617 via machine learning
Authors: Rezaei Amir 
Published: November 2023

Purpose
This paper aims to study the feasibility of using machine learning in hot corrosion prediction of Inconel 617 alloy.

Design/methodology/approach
By examination of the experimental studies on hot corrosion of Inconel 617, a data set was built for machine learning models. Apart from the alloy composition, this paper included the condition of hot corrosion like time and temperature, and the composition of the saline medium as independent features, while the specific mass change is set as the target feature. In this paper, linear regression, random forest and XGBoost are used to predict the specific mass gain of Inconel 617.

Findings
XGBoost yields the coefficient of determination (R2) of 0.98, which was highest among models. Also, this model recorded the lowest value of mean absolute error (0.20). XGBoost had the best performance in predicting specific mass gain of the alloy in different times at temperature of 900°C. In sum, XGBoost shows highest accuracy in predicting specific mass gain for Inconel 617.

Originality/value
Using machine learning to predict hot corrosion in Inconel 617 marks a substantial progress in this domain and holds promise for simplifying the development and evaluation of novel materials featuring enhanced hot corrosion resilience.

Published: November 2023

PurposeThe current study investigates the role of consumer ethnocentrism (CE) in the context of locally produced organic food. This research work further extends the extended theory of planned behavior (TPB) model by examining the mediating effect of extended TPB variables (ATT, SN, PBC, PV) between CE and PI for locally produced organic food.Design/methodology/approachData were obtained from the visitors of two shopping malls situated in a large, heavily populated city of India using survey method. Further, two-step approach was applied to analyze the hypothesized model.FindingsFindings indicate that CE is a substantial determinant of PI for locally produced organic food. Moreover, extended TPB mediates the relation between CE and PI for locally produced organic food.Practical implicationsPost Covid-19, market size of organic food is rapidly growing in India. In this regard, this study presents useful implications for the marketers of organic food for gaining better consumer insights to further develop appropriate marketing strategies.Originality/valueCE has been found to be a useful predictor of their food attitudes. However, studies, investigating the role of CE in the context of sustainable food consumption, are scant. Moreover, studies exploring the mediating effect of extended TPB variables are also very limited.
Does openness of articles get higher attention in altmetric? An investigation of medical discipline
Authors: Mukherjee Simly , Nath Amit , Mazumder Jhantu , Jana Sibsankar 
Published: November 2023

Purpose
This paper aimed to explore the presence of altmetric data across the sub-categories of the medical science discipline and also explore whether the openness of articles results in (dis)advantage for altmetrics mentions.

Design/methodology/approach
The research implies data carpentry methods for gathering bibliographic data related to narrow fields of medical science discipline from the Scopus database with at least one Indian author affiliation during 2012–2021. The corresponding data were also collected from three different sources: Altmetric.com, Mendeley.com and Unpaywall.org, using OpenRefine and REST/API calls. Further, the authors observed open access altmetric advantages (OAAA) and categorical OAAA (COAAA) across seven altmetric platforms for all articles as well as discipline-wise.

Findings
The result shows that the overall coverage of altmetric events is still low, but it shows an increasing trend from the past. Mendeley has the largest coverage; almost 97.12% of publications are covered. The health policy discipline has extensive coverage across altmetric platforms (nearly 57.40% of publications in altmetrics and 99.23% in Mendeley), whereas the drug guides has the lowest (almost 0.92% in Altmetrics and 77.05% in Mendeley). Moreover, the OA articles have been highly covered in altmetrics than those of non-OA articles, and bronze OA articles covered mostly compared to others. News registered with the significant OA altmetric advantages across disciplines. Categorically, bronze and hybrid OA have the largest altmetric advantages.

Originality/value
This research is a unique attempt to apply OAAA and COAAA to explore OA altmetric advantages of narrow subject categories of medical science disciplines.
The status of women’s empowerment in the aquaculture sector in Kenya
Authors: Adam Rahma Isaack , Sufian Farha Deba , Njogu Lucy 
Published: November 2023

Purpose
Women’s empowerment remains a key development challenge in Kenya. The purpose of this study is to attempt to understand the status of women’s empowerment and the key contributors to their disempowerment in Kenya’s aquaculture sector.

Design/methodology/approach
A cross-sectional survey was conducted on 534 male and female fish farmers from 300 households drawn from six counties in Kenya (Kakamega, Kisumu, Kisii, Kiambu, Meru and Nyeri). The Abbreviated Women’s Empowerment in Agriculture Index (A-WEAI) was adapted to Abbreviated Women’s Empowerment in Fisheries and Aquaculture Index (A-WEFI) to suit the aquaculture and fisheries sub-sector. The adapted A-WEFI was then used to estimate and the status of women’s and men’s using five domains of empowerment (5DE) and a gender parity index (GPI). Data were analysed using descriptive statistics, Cramer’s V and sensitivity analysis as test statistics.

Findings
About 86% of the men and 80% of the women were classified as empowered. The mean score of the 5DE was 0.93 and 0.95 for women and men, respectively. In addition, 82% of the households achieved gender parity, suggesting that for such households, empowerment of men was no greater than that of women. Overall, the results suggest no major differences between the empowerment of women and men. Findings suggest areas of improvement in empowerment: when observed separately, women report lack of agency in production, resource, time-use and allocation and leadership.

Originality/value
This paper adapts the A-WEAI to the fisheries and aquaculture context, in bid to bridge the gap in standard women’s empowerment measurement methods in this area. Also, there are limited empirical studies on the multifaceted empowerment of women in aquaculture in Kenya. The findings are meant to serve as a point of reference for policymakers, as they develop gender-responsive intervention programmes, and in implementing gender mainstreaming in Kenya.
Climate change adaptation and mitigation at individual level: knowledge and attitudes among school teachers in Kalutara district
Authors: Rupasinghe Chintha Suranjalee , De Silva Weliange Shreenika 
Published: November 2023

Purpose
Climate change is the biggest global health threat of the 21st century. Its impacts scatter through every stratum of society placing the marginalized clusters at the highest vulnerability and calling for action at all levels. Adaptation enhances resilience, whereas mitigation minimizes the anthropogenic forces of climate change; these are crucial initiatives for climate-resilient sustainable development. The aim of this study was to determine the knowledge and attitudes on climate change adaptation and mitigation at individual level and assess related factors.

Design/methodology/approach
A descriptive study is done to assess the knowledge and attitudes of school teachers in three educational zones of the Kalutara district using random cluster sampling. A self-administered questionnaire including 25 equally weighted questions to assess knowledge and 10 statements to assess attitudes was used.

Findings
The response rate was 98.8% [n = 618] and 23% of the study population had poor knowledge of climate change adaptation and mitigation at the individual level. Favorable attitudes were observed among more than 65% of participants for all the statements on climate change adaptation and mitigation. Average family income, working duration, involvement in school environmental societies and highest education qualification showed a significant positive association, whereas age and current grade had a significant negative association with good knowledge. The level of knowledge had no significant variation among male and female teachers.

Originality/value
Overall knowledge was poor among more than 20% of the teachers highlighting the need for school and community-based awareness programs to be implemented to address the issue.

Authors: Braaten Claire Nolasco , Tsai Lily Chi-Fang 
Published: November 2023

Purpose
This study aims to analyze corporate mail and wire fraud penalties, using bounded rationality in decision-making and assessing internal and external influences on prosecutorial choices.

Design/methodology/approach
The study analyzed 467 cases from 1992 to 2019, using data from the Corporate Prosecution Registry of the University of Virginia School of Law and Duke University School of Law. It examined corporations facing mail and wire fraud charges and other fraud crimes. Multiple regression linked predictor variables to the dependent variable, total payment.

Findings
The study found that corporate penalties tend to be lower for financial institutions or corporations in countries with US free trade agreements. Conversely, penalties are higher when the company is a U.S. public company or filed in districts with more pending criminal cases.

Originality/value
This study’s originality lies in applying the bounded rationality model to assess corporate prosecutorial decisions, unveiling external factors’ influence on corporate penalties.
Critical examination of academic marketing and service research’s philosophical foundation
Authors: Tronvoll Bård , Edvardsson Bo 
Published: November 2023

Purpose
The philosophical foundations determine how an academic discipline identifies, understands and analyzes phenomena. The choice of philosophical perspective is vital for both marketing and service research. This paper aims to propose a social and systemic perspective that addresses current challenges in service and marketing research by revisiting the philosophy of science debate.

Design/methodology/approach
The paper revisits the philosophy of science debate to address the implications of an emergent, complex and adaptive view of marketing and service research. It draws on critical realism by combining structuration and systemic perspectives.

Findings
A recursive perspective, drawing on structures and action, is suggested as it includes multiple actors’ intentions and captures underlying drivers of market exchange as a basis for developing marketing and service strategies in practice. This is aligned with other scholars arguing for a more systemic, adaptive and complex view of markets in light of emerging streams in academic marketing and service research, ranging from value cocreation, effectuation, emergence and open source to empirical phenomena such as digitalization, robotization and the growth of international networks.

Research limitations/implications
The reciprocal dynamic between individuals and the overarching system provides a reflexivity approach intrinsic to the service ecosystem. This creates new avenues for research on marketing and service phenomena.

Originality/value
This paper discusses critics, conflicts and conceptualization in service research. It suggests a possible approach for service research and marketing scholars capable of responding to current complexities and turbulence in economic and societal contexts.
Impact of animal origin of milk, processing technology, type of product, and price on the Boursin cheese choice process: Insights of a discrete choice experiment and eye tracking

Published: November 2023

AbstractBoursin is a versatile semisoft cheese that can be made with different types of milk. While widely distributed in the European and North American markets, Boursin is produced to a limited extent in Brazil despite its commercial potential. This scenario encourages consumer‐oriented product development studies by facilitating data collection with less bias and fewer product preconceptions, thus favoring the investigation of technological aspects of commercial interest. This study evaluates Brazilians’ perceptions regarding different versions of Boursin cheese, with the aim of gaining a better understanding of the factors related to choosing cheese. Four attributes related to cheese production were evaluated at three different levels using two discrete choice experiments: one with eye tracking (n = 20) and another without (n = 312). These attributes included “type of processing” (evaluating pasteurization, ohmic heating, and preparation with raw milk), “animal origin of milk” (cow, goat, or buffalo milk), “type of product” (traditional, light, and lactose‐free versions), and “price” (10.99, 13.99, and 16.99 BRL). Information regarding processing with ohmic heating did not affect the probability of Boursin being chosen, suggesting that consumers are open to using this emerging technology in Boursin cheese. However, information on being made with goat, buffalo, and raw milk negatively impacted the probability of choice, along with the price of 16.99 BRL. The frequency of cheese consumption and the level of health concerns also affected the probability of choosing the product.Practical ApplicationIdentifying the relationship between extrinsic attributes presented on the Boursin cheese label and the consumer's choice process can aid the communication process with the target audience and reveal how some technological issues of interest to manufacturers are perceived. This study indicates how information regarding the animal origin of the milk (cow, goat, and buffalo), the type of processing (pasteurization, ohmic heating, and raw milk), the version of the product (traditional, light, and lactose‐free), and the price affect the consumer choice process. The results provide insights that can be applied to product processing and designing labels.

Published: November 2023

AbstractSeveral gut microbial species within the Faecalibacterium genus have emerged as promising next‐generation probiotics (NGP) due to their multifunctional protective effects against gastrointestinal and systemic disorders. To enable clinical studies and further applications, improved methods for cultivating Faecalibacterium must be developed in compliance with current Good Manufacturing Practice regulations, which is complicated by its oxygen sensitivity and complex nutritional requirements. Different yeast‐based nutrients (YBNs), including yeast extracts (YEs) and yeast peptones (YPs), are ubiquitously used when cultivating microbes to supply a broad range of macro‐ and micronutrients. In this study, we evaluated six experimental YBNs, namely three YEs, two YPs and a yeast cell wall product (YCW), and eight B‐vitamins in the cultivation of Faecalibacterium duncaniae A2‐165, former Faecalibacterium prausnitzii, using growth assays in microtitre plates, dose‐effect studies in Hungate tube fermentations and fully controlled bioreactor experiments. We demonstrated that YEs promote F. duncaniae A2‐165 growth in a nutritionally limited medium, while YPs and YCW lacked essential growth factors for enabling cell propagation. High cell density was obtained in controlled bioreactors using a medium containing 2–4% of a selected YE and 1% casein peptone (3.4 ± 1.7 × 109–5.1 ± 1.3 × 109 cells mL−1). Among all tested B‐vitamins, we identified B5 as a strong growth promoter. Replacing casein peptone with YP and supplementing with vitamin B5 further increased biomass by approximately 50% (6.8 ± 1.7 × 109 cells mL−1). Hence, empirical selection of YE, YP and B5 allowed formulation of a high‐yielding animal allergen‐free nutritive medium to produce F. duncaniae A2‐165. Selecting nutritionally suitable YBNs and combining these with other key nutrients are important steps for optimizing production of NGP with high yields and lower cost.
Low human sperm motility coexists with sperm nuclear DNA damage and oxidative stress in semen
Authors: Gill Kamil , Machałowski Tomasz , Harasny Patryk , Grabowska Marta , Duchnik Ewa , Piasecka Małgorzata 
Published: November 2023

AbstractBackgroundLow sperm motility, one of the common causes of male infertility, is associated with abnormal sperm quality. Currently, important sperm/semen biomarkers are sperm chromatin status and oxidation‒reduction potential (ORP) in semen. Because the association between sperm motility and these biomarkers is still not fully clarified, our study was designed to verify the distribution and risk of sperm DNA fragmentation (SDF) and oxidative stress in semen in asthenozoospermic men.Materials and methodsThis study was carried out on discharged sperm cells of asthenozoospermic men (isolated asthenozoospermia or coexisted with reduced sperm number and/or morphology), nonasthenozoospermic men (reduced total sperm count and/or sperm morphology) (experimental groups) and normozoospermic men (proven and presumed fertility) (control group). Basic semen analysis was evaluated according to the 6th edition of the World Health Organization manual guidelines. SDF was assessed using the sperm chromatin dispersion test, while static(s) ORP in semen was measured by means of a MiOXSYS analyser.ResultsThe men from the asthenozoospermic group had lower basic semen parameters than those from the control and nonasthenozoospermic groups. In men with poor sperm motility SDF and sORP, prevalence and risk for > 20% SDF (high level of DNA damage) and for > 1.37 sORP (oxidative stress) were significantly higher than those of control and nonasthenozoospermic subjects. The risk for sperm DNA damage and oxidative stress in asthenozoospermic men was over 10‐fold higher and almost 6‐fold higher than those in control subjects and almost or over 3‐fold higher than those in nonasthenozoospermic men.Conclusions and discussionPoor human sperm motility coexisted with low basic sperm quality. Sperm DNA damage and oxidative stress in semen were much more frequent in asthenozoospermia. These abnormalities can decrease the sperm fertilizing capability under both natural and medically assisted reproduction conditions. Thus, in asthenozoospermia, the evaluation of sperm chromatin status and oxidation–reduction potential in semen is justified and inevitable, and the appropriate antioxidant therapy can be suggested.
Collective bargaining and power: Wage premium of collective agreements in Europe 2002–2018
Authors: Zwysen Wouter , Drahokoupil Jan 
Published: November 2023

AbstractThis article uses the European Structure of Earnings Survey to describe the evolution of collective bargaining coverage in European countries during 2002–2018 and how this affected the pay premium associated with being covered. Pay premia are an outcome of negotiations, reflecting the bargaining power on behalf of employees as well as the system of coverage, separately for the public and private sector. Descriptively, we show a decline in collective bargaining coverage linked to a general reduction in the pay differences. This hides much variation though. In a multivariate analysis of changes over time, we show that centrally bargained agreements are associated with larger pay premia if more people are covered and in countries and sectors with stronger trade unions. As this power declines over time, so do wage premia. At higher rates of coverage, there can be a spillover effect where wages for all workers increase, thereby reducing the premia.
Explaining and exploring the dynamics of parent–child interactions and children's causal reasoning at a children's museum exhibit

Published: November 2023

AbstractThis study examines how parents' and children's explanatory talk and exploratory behaviors support children's causal reasoning at a museum in San Jose, CA in 2017. One‐hundred‐nine parent–child dyads (3–6 years; 56 girls, 53 boys; 32 White, 9 Latino/Hispanic, 17 Asian‐American, 17 South Asian, 1 Pacific Islander, 26 mixed ethnicity, 7 unreported) played at an air flow exhibit with a nonobvious causal mechanism. Children's causal reasoning was probed afterward. The timing of parents' explanatory talk and exploratory behaviors was related to children's systematic exploration during play. Children's exploratory behavior, and parents' goal setting during play, were related to children's subsequent causal reasoning. These findings support the hypothesis that children's exploration is related to both internal learning processes and external social scaffolding.
