Comparative genomic analysis ofPlanctomycetotapotential towards complex polysaccharide degradation identifies phylogenetically distinct groups of biotechnologically relevant microbes
Authors: Klimek Dominika , Herold Malte , Calusinska Magdalena 
Published: January 2024

ABSTRACTThe outstanding hydrolytic potential of thePlanctomycetotaphylum for complex polysaccharide degradation has recently been acknowledged based on the numerous carbohydrate-active enzymes (CAZymes) encoded in their genomes. However, mainly members of thePlanctomycetiaclass have been characterised up to now, and little is known about the degrading capacities of the otherPlanctomycetota. Our in-depth characterisation of the available planctomycetotal genomic resources increased our knowledge of the carbohydrolytic capacities ofPlanctomycetota. We showed that this single phylum encompasses a wide variety of the currently known CAZyme diversity assigned to glycoside hydrolase families, and that many members are characterised by a high versatility towards complex carbohydrate degradation, including lignocellulose. We also highlighted members of theIsosphaerales, Pirellulales, SedimentisphaeralesandTepidisphaeralesorders as having the highest encoded hydrolytic potential of thePlanctomycetota. Furthermore, members of a yet uncultivated group affiliated toPhycisphaeraleswere identified as an interesting source of novel, lytic polysaccharide monooxygenases that could boost lignocellulose degradation. Surprisingly, manyPlanctomycetotafrom anaerobic digestion reactors were shown to encode CAZymes targeting algal polysaccharides – this opens new perspectives for algal biomass valorisation in biogas processes. Our study provides a new perspective on planctomycetotal carbohydrolytic potential, highlighting distinct phylogenetic groups which could provide a wealth of diverse, potentially novel CAZymes of industrial interest.
Optoacoustic Cooling of Traveling Hypersound Waves
Authors: Blázquez Martínez Laura , Wiedemann Philipp , Zhu Changlong , Geilen Andreas , Stiller Birgit 
Published: January 2024

We experimentally demonstrate optoacoustic cooling via stimulated Brillouin-Mandelstam scattering in a 50 cm long tapered photonic crystal fiber. For a 7.38 GHz acoustic mode, a cooling rate of 219 K from room temperature has been achieved. As anti-Stokes and Stokes Brillouin processes naturally break the symmetry of phonon cooling and heating, resolved sideband schemes are not necessary. The experiments pave the way to explore the classical to quantum transition for macroscopic objects and could enable new quantum technologies in terms of storage and repeater schemes.

Device-dependent click-through rate estimation in Google organic search results based on clicks and impressions data
Authors: Strzelecki Artur , Miklosik Andrej 
Published: January 2024

PurposeThe landscape of search engine usage has evolved since the last known data were used to calculate click-through rate (CTR) values. The objective was to provide a replicable method for accessing data from the Google search engine using programmatic access and calculating CTR values from the retrieved data to show how the CTRs have changed since the last studies were published.Design/methodology/approachIn this study, the authors present the estimated CTR values in organic search results based on actual clicks and impressions data, and establish a protocol for collecting this data using Google programmatic access. For this study, the authors collected data on 416,386 clicks, 31,648,226 impressions and 8,861,416 daily queries.FindingsThe results show that CTRs have decreased from previously reported values in both academic research and industry benchmarks. The estimates indicate that the top-ranked result in Google's organic search results features a CTR of 9.28%, followed by 5.82 and 3.11% for positions two and three, respectively. The authors also demonstrate that CTRs vary across various types of devices. On desktop devices, the CTR decreases steadily with each lower ranking position. On smartphones, the CTR starts high but decreases rapidly, with an unprecedented increase from position 13 onwards. Tablets have the lowest and most variable CTR values.Practical implicationsThe theoretical implications include the generation of a current dataset on search engine results and user behavior, made available to the research community, creation of a unique methodology for generating new datasets and presenting the updated information on CTR trends. The managerial implications include the establishment of the need for businesses to focus on optimizing other forms of Google search results in addition to organic text results, and the possibility of application of this study's methodology to determine CTRs for their own websites.Originality/valueThis study provides a novel method to access real CTR data and estimates current CTRs for top organic Google search results, categorized by device.

Published: January 2024

Purpose The purpose of this paper is to analyze the impact of different information source on consumer attitudes toward genetically modified food.Design/methodology/approach The data used in this study are obtained from a large-scale nationwide consumers' survey in urban China conducted by the China Center for Agricultural Policy, Peking University, in 2020. A descriptive analysis between information sources and consumer attitudes toward GM food was conducted. Based on the collected data, an econometric model on the determinants of consumer attitudes was constructed and used for analysis.Findings This study shows that the impact of new media is currently no different than that of traditional media, indicating that the media campaign successfully reduced the spread of rumors and misinformation regarding GM food. Moreover, this study also shows that consumers whose main information source regarding GM foods is school hold more positive feelings toward such food.Originality/value This study contributes to the existing literature by examining the impact of information source on consumer attitudes toward GM food. To reverse consumers' negative attitudes, China has launched a widespread media campaign since the first decade of the 2000s. Results of this study show that authorities' efforts to manage and surveil new media have yielded the desired outcome.

Authors: Teunissen Lauranna , Van Royen Kathleen , Goemans Iris , Verhaegen Joke , Pabian Sara , De Backer Charlotte , Vandebosch Heidi , Matthys Christophe 
Published: January 2024

PurposeExplore what popular food influencers among Flemish emerging adults portray in their Instagram recipe posts in terms of (1) references to food literacy, (2) nutritional value, (3) rational and emotional appeals and (4) the relation between the nutritional value and rational/emotional appeals.Design/methodology/approachA content and nutritional analysis of Instagram recipe posts from seven food influencers (N = 166).FindingsFindings reveal that food influencers rarely embed references to food literacy in their recipe posts, especially regarding meal planning, food selection, meal consumption and evaluating food-related information. Only in 28.9% of the posts information was given on how to prepare a recipe. Second, 220 recipes were included in the 166 recipe posts, of which the majority (65%) were main course meals that met at least six of the 11 nutrient criteria for a healthy main meal (67.2%). Finally, food influencers promote their recipe posts as positive narratives, focusing on the tastiness (66%) and convenience (40.9%) of meals.Originality/valueThis is the first study to evaluate what food influencers post nutritionally in their Instagram recipes, as well as how they promote these recipes. Health promotors should note the influential role of food influencers and seek ways to collaborate to provide information on how food literacy cues can be embedded in influencers' communications and provide insights into how influencers' recipes can be optimised.
“I’m not white”: counter-stories from “mixed race” women navigating PhDs
Authors: Garrett Rhianna 
Published: January 2024

PurposeThis paper critiques institutional whiteness and racial categorisation in UK higher education. This is done through the representation of the complex narratives of “mixed race” women navigating their PhD experiences in predominantly white institutions, when their identities have proximity to whiteness.Design/methodology/approachThis study introduces five vignettes of “mixed race” women, gathered from a wider study of 27 PhDs and early career researchers in UK higher education. The paper employs Yuval-Davis’ framework of belonging and bell hooks' approach to chosen versus forced marginality to create a conceptual framework based on fluid agency and empowerment, recognising belonging as an ongoing process.FindingsThe findings reveal how “mixed race” women can occupy a liminal space between belonging to and rejecting racial categorisation, as they attempted to situate their self-identifications within the boundaries of institutional whiteness.Research limitations/implicationsThe study only utilises a small sample size of five counter-stories from a larger study on PhD career trajectories, limiting its empirical claims. It also only engages with “mixed race” women who have proximity to whiteness, encouraging research on different “mixed race” intersections.Practical implicationsThis paper encourages more discussion around “mixed race” experiences of UK higher education and critical engagement with higher education’s reliance on statistical data to understand racialised communities.Originality/valueThis paper contributes new empirical insights into how whiteness is experienced when “mixed race” women negotiate their relation to it in UK higher education. It also provides theoretical advancements into understanding of institutional whiteness and critically engages with racial categorisation.

Authors: Vilkaite - Vaitone Neringa , Kirse Sigita , Adomaviciute - Sakalauske Karina , Dikcius Vytautas , Zimaitis Ignas 
Published: January 2024

PurposeThis study aims to explore the use of gamification elements by micro and small e-tailers to enhance customer loyalty. Additionally, this research seeks to identify the most promising gamification elements that can be utilised for this purpose.Design/methodology/approachThe authors adopt a qualitative approach to examine the impact of gamification on online customer loyalty to micro and small e-tailers. Data were gathered using a combination of two types of expert interviews. Semi-structured interviews were held with micro and small e-tailers while large e-tailers served as the control group. Structured interviews based on multi-criteria decision analysis (MCDA) models were conducted to determine the most promising gamification elements.FindingsThe content analysis reveals that gamification has significant potential for fostering customer loyalty and offering various other benefits. However, small e-tailers often refrain from implementing gamification solutions due to the resource requirements in terms of finances, time, information technology and human capital. By assigning weights as an essential step in MCDA models, the authors determined that badges, medals, quests, avatars and competitions are the most promising gamification options for small e-tailers’ efforts to enhance customer loyalty.Originality/valueThe study makes a unique contribution to the understanding of the usefulness of gamification in augmenting customer loyalty and identifying essential gamification elements for micro and small e-tailers.

Authors: Oh Sein , Mon Lorri 
Published: January 2024

Purpose
By examining types of literacies taught by public libraries and the modes through which these programs were offered, this study aims to explore how public libraries might integrate data literacy training for the general public into existing library educational programs.

Design/methodology/approach
This study examined programs offered in 30 US public libraries during 2019 and 2020 to better understand types of literacy education announced to the public through library website listings and Facebook Events pages.

Findings
While public libraries offered educational programs in literacy areas ranging from basic reading and writing to technology, vocational skills, health literacy and more, data literacy training was not widely offered. However, this study identified many already-existing programs highly compatible for integrating with data literacy training.

Originality/value
This study offered new insights into both the literacies taught in public library programs as well as ways for public libraries to integrate data literacy training into existing educational programming, in order to better provide data literacy education for the general public.

Authors: Ebrahimi Maryam , Daneshvar Amir , Valmohammadi Changiz 
Published: January 2024

PurposeTo gain and differentiate competitive advantage, the sustainable service quality is a determining factor that railway companies can use. The purpose of this study is to identify both the importance and performance of rail transportation service quality factors in a case study as well as determine the most influential quality features.Design/methodology/approachA comprehensive approach namely importance–performance analysis (IPA) technique and decision-making trail and evaluation laboratory (DEMATEL), and interpretive structural modeling (ISM) and Matriced’ Impacts Croisés Multiplication Appliquée á un Classement (MICMAC) techniques was utilized.FindingsThe relative position of each attribute is specified on the IPA matrix proposing four strategies of concentrate here, keep up the good work, low priority and possible overkill. This study reveals that attributes of “the company cares about having a good society” are the most influential factor, and “having good business relations with shareholders” is the most permeable factor. Actually, consumers pay attention to how companies act toward society and maintain communication with shareholders. Through ISM technique and by summing the row and column of the consistency matrix, the attributes were partitioned into four levels. Also, MICMAC analysis identified the four clusters of linkage, independent, autonomous and dependent status of the attributes in terms of the driving power and dependence power.Research limitations/implicationsDue to the nature of single case study methodology, caution should be taken into consideration regarding the generazability of the obtained results.Originality/valueThe hybrid DEMATEL-ISM technique is used to analyze service quality factors in Iran’s transportation industry, which can be utilized in other industries as well as other countries.

Authors: Khan Shanza Maryam , Akhtar Shahzad 
Published: January 2024

PurposeThe study investigates the impact of competition and concentration on bank risk-taking behavior and stability in the South Asian Association for Regional Cooperation (SAARC) region.Design/methodology/approachData from 100 banks from 2013 to 2021 was analyzed using dynamic and static measures by using dynamic system GMM.FindingsResults showed that higher competition reduces stability, while concentration in the banking sector produces stability and reduces risk-taking behavior. The findings suggest that regulatory agencies should take different actions based on the degree of banking market concentration to enhance banking sector stability in the SAARC area.Practical implicationsThe research helps regulators and decision-makers establish capital requirements at levels that would prevent banks from increasing their risk-taking in order to boost profits and, therefore, reduces hazardous practices that might increase the risk.Originality/valueThe research helps establish capital requirements to prevent banks from increasing risk-taking to boost profits and avoid hazardous practices that could increase nonperforming loans and bank failure risks.
“If you want peace avoid interpersonal conflict”: a moderating role of organizational climate
Authors: Singh Anurag , Waldia Neelam 
Published: January 2024

PurposeThis study examines the impact of interpersonal conflict on workplace aggression. Moreover, the moderating role in the association between interpersonal conflict and workplace aggression has been examined.Design/methodology/approachThe research is grounded on the cognitive appraisal theory, which posits that interpersonal conflict contributes to aggression in the workplace. A sample of n = 250 employees from the steel industry in India was selected in two waves. The authors utilized Hayes' PROCESS macro v4.1 for path analysis.FindingsThe research reveals that interpersonal conflict is positively and significantly related to workplace aggression. Moreover, organizational climate is negatively associated with workplace aggression. The moderation analysis has revealed that organizational climate negatively moderates the relationship between interpersonal conflict and workplace aggression.Practical implicationsThis study suggests that recognizing the significance of the organizational climate, companies can proactively curtail the progression of disputes into hostile behaviors. Nurturing a positive workplace climate becomes paramount, as it acts as a buffer against conflict escalation. Educating both staff and managers about the diverse forms of aggression and implementing appropriate protocols to address such behaviors are crucial steps toward fostering a positive climate.Originality/valueThis study provides new insights into the existing literature on workplace aggression, interpersonal conflict and organizational climate for future research.
Effect of banks’ ownership structure on financial performance: evidence from banks in an emerging market
Authors: Kirimi Peter Njagi 
Published: January 2024

Purpose
This study aims to examine the effect of ownership structure on financial performance of commercial banks in Kenya.

Design/methodology/approach
The data were collected from audited financial statements of 39 commercial banks in Kenya for the period 2009–2020.

Findings
Regression results found evidence of ownership structure explaining commercial banks’ financial performance. The results found a negative association between state ownership and net interest margin, a negative association between management ownership and net interest margin and a negative association between institutional ownership and return on assets.

Practical implications
Based on the findings, commercial bank management should therefore devise ownership structure policies that are geared toward boosting their financial performance both in the short run and the long run. Second, this study recommends a minority shareholding of the state in commercial banks to deter political interference, protect investors’ wealth from erosion and allow the majority shareholders to adopt a strong corporate governance mechanism for higher financial performance. Banks with a high percentage of state ownership should consider partial privatization to improve corporate governance practices. Third, banks should adopt a managerial ownership policy limiting the proportion of equity stock held by executives to limit their powers in strategic decision-making. Fourth, this study proposes a percentage limit on the equity stock of an institutional investor to eliminate bureaucracy in strategic decision-making and protect investors’ wealth.

Originality/value
The study finding is meant to inform regulation and operation policies in the banking sector and contribute to the literature on ownership structure, especially in the banking sector.
Corporate cash holdings and financial performance: moderating effect of corporate governance and family ownership
Authors: Ahmed Jameel , Tahir Muhammad 
Published: January 2024

PurposeThis study aims to examine the effect of corporate cash holdings on financial performance. Additionally, it investigates the moderating effect of corporate governance and family ownership on the link between corporate cash holdings and financial performance.Design/methodology/approachThis study uses secondary data regarding the sample of 81 firms listed in the Karachi Stock Exchange (KSE) 100 index from 2011 to 2020. The present study applies the system generalized method of moments (GMM) to estimate the dynamic financial performance models.FindingsThe findings reveal that corporate cash holding is significantly positively linked with financial performance. Further, the findings indicate that the board size and chief executive officer (CEO) duality strengthen the association between cash holdings and financial performance, whereas CEO gender and family ownership weaken the positive effect of cash holdings on financial performance. Furthermore, the findings suggest that Covid-19 significantly negatively affected the financial performance of Pakistani firms.Practical implicationsThe findings have several policy implications. First, policymakers need to increase the board of directors' role in observing the firms' cash-holding behaviour. Policymakers may also formulate policies providing stronger protection for minority shareholders from majority shareholders.Originality/valueTo the best of the authors' knowledge, this study is the first to examine how corporate governance and family ownership influence the link between corporate cash holdings and financial performance in the context of Pakistan.
