Published: January 2023

AbstractAccumulating evidence suggests mitochondria as key modulators of normal and premature aging, yet whether primary deficiency of oxidative phosphorylation (OXPHOS) can cause progeroid disease remains unclear. Here, we show that mice with severe isolated respiratory complex III (CIII) deficiency display nuclear DNA damage, cell cycle arrest, aberrant mitoses, cellular senescence, and laminopathy-like nuclei in the affected organs such as liver and kidney, and a systemic phenotype strikingly resembling juvenile-onset laminopathic and DNA repair-deficient progeroid syndromes. Mechanistically, CIII deficiency triggered presymptomatic cancer-like c-MYC upregulation followed by excessive anabolic metabolism and illicit cell proliferation against lack of energy and biosynthetic precursors. CIII-independent coenzyme Q oxidation dampened mitochondrial integrated stress response and the c-MYC induction, suppressed the illicit proliferation, and prevented juvenile lethality despite that canonical OXPHOS-linked functions remained uncorrected. Inhibition of c-MYC by expression of a dominant-negative Omomyc protein relieved the DNA damage in CIII-deficient hepatocytesin vivo. Our results unequivocally connect primary OXPHOS deficiency to genomic instability and progeroid disease and suggest that targeting c-MYC and aberrant cell proliferation may provide novel therapeutic strategies in mitochondrial diseases.

AbstractInter-species comparisons are key to deriving an understanding of the behavioral and neural correlates of human cognition from animal models. We perform a detailed comparison of macaque monkey and human strategies on an analogue of the Wisconsin Card Sort Test, a widely studied and applied multi-attribute measure of cognitive function, wherein performance requires the inference of a changing rule given ambiguous feedback. We found that well-trained monkeys rapidly infer rules but are three times slower than humans. Model fits to their choices revealed hidden states akin to feature-based attention in both species, and decision processes that resembled a Win-stay lose-shift strategy with key differences. Monkeys and humans test multiple rule hypotheses over a series of rule-search trials and perform inference-like computations to exclude candidates. An attention-set based learning stage categorization revealed that perseveration, random exploration and poor sensitivity to negative feedback explain the under-performance in monkeys.
Travel vlogs influencing tourist decisions: information preferences and gender differences
Authors: Cheng Wenyi , Tian Ruwen , Chiu Dickson K.W. 
Published: January 2023

PurposeAs independent travel has become increasingly popular in recent years, factors influencing users’ attitudes and behaviors should be explored. Besides, the rise of video platforms like YouTube, Bilibili and TikTok has led to the flourishing of user generated content (UGC), among which travel vlogs have become convenient and essential references for tourists before and while they travel on their own.Design/methodology/approachThis research used quantitative analysis through a survey designed for young people, as most vlog viewers are in those age groups, to explore the attitudes and perceptions of vlog preference, attitudes and cognizance of travel vlogs among different gender, guided by the decision-making theory and preference theory with 455 participants.FindingsSurvey results showed that both genders have common choices regarding travel vlog preference, attitudes, sharing and cognizance. Yet, gender differences appear in some cognition of travel vlogs and specific preferences, such as information searching habits, trusty travel and information sources.Originality/valueExisting studies focus on the influence of platforms on users, but scant studies focus on user perceptions of vlogs as a new information carrier for young people in East Asia, especially regarding gender differences, which is crucial in media-based marketing. This research provides practical suggestions to marketers and vloggers to attract and engage different genders of young people and theoretical implications on decision and preference theories.
Corporate social responsibility commitment of women directors through audit committees: evidence from international firms
Authors: Pucheta-Martínez María Consuelo , Bel-Oms Inmaculada , Gallego-Álvarez Isabel 
Published: January 2023

PurposeThis paper explores the impact of some audit committees' characteristics (executive and independent directors and directors' attendance at audit committee meetings) on CSR reporting. Moreover, it also aims to test the moderating effect of women directors on boards on the association between audit committees' characteristics and CSR disclosure.Design/methodology/approachThis study uses an international sample comprising 13,264 firm-year observations of non-financial firms from 2007 to 2018.FindingsThe results show that executive and independent directors on audit committees have a negative impact on CSR reporting, while the directors' attendance at audit committees meetings is positively associated with CSR disclosure. This study’s results also provide convincing evidence that female directors on corporate boards positively moderate the negative association between executive and independent directors on audit committees and CSR disclosure. Finally, the findings also show that female directors on corporate boards do not moderate the positive impact of directors' attendance at audit committees' meetings on CSR information.Research limitations/implicationsThis study is focused on attributes of audit committees based on a sample of international listed non-financial firms.Originality/valueThis is the first study analyzing the moderating role of female directors on boards on the relations between both executive directors on audit committees and CSR reporting and the average attendance of directors at audit committees' meetings and CSR disclosure.
A novel improved teaching and learning-based-optimization algorithm and its application in a large-scale inventory control system
Authors: Chen Zhixiang 
Published: January 2023

PurposeThe purpose of this paper is to propose a novel improved teaching and learning-based algorithm (TLBO) to enhance its convergence ability and solution accuracy, making it more suitable for solving large-scale optimization issues.Design/methodology/approachUtilizing multiple cooperation mechanisms in teaching and learning processes, an improved TBLO named CTLBO (collectivism teaching-learning-based optimization) is developed. This algorithm introduces a new preparation phase before the teaching and learning phases and applies multiple teacher–learner cooperation strategies in teaching and learning processes. Applying modularization idea, based on the configuration structure of operators of CTLBO, six variants of CTLBO are constructed. For identifying the best configuration, 30 general benchmark functions are tested. Then, three experiments using CEC2020 (2020 IEEE Conference on Evolutionary Computation)-constrained optimization problems are conducted to compare CTLBO with other algorithms. At last, a large-scale industrial engineering problem is taken as the application case.FindingsExperiment with 30 general unconstrained benchmark functions indicates that CTLBO-c is the best configuration of all variants of CTLBO. Three experiments using CEC2020-constrained optimization problems show that CTLBO is one powerful algorithm for solving large-scale constrained optimization problems. The application case of industrial engineering problem shows that CTLBO and its variant CTLBO-c can effectively solve the large-scale real problem, while the accuracies of TLBO and other meta-heuristic algorithm are far lower than CLTBO and CTLBO-c, revealing that CTLBO and its variants can far outperform other algorithms. CTLBO is an excellent algorithm for solving large-scale complex optimization issues.Originality/valueThe innovation of this paper lies in the improvement strategies in changing the original TLBO with two-phase teaching–learning mechanism to a new algorithm CTLBO with three-phase multiple cooperation teaching–learning mechanism, self-learning mechanism in teaching and group teaching mechanism. CTLBO has important application value in solving large-scale optimization problems.
The future of leadership: new digital skills or old analog virtues?
Authors: Gilli Katharina , Lettner Nicole , Guettel Wolfgang 
Published: January 2023

PurposeBusiness leaders are facing a change of role as digitalization continues to intensify in organizations. As technological change is bringing back supposedly old virtues of leadership, this study aims to explain the impact digital transformation has on leadership due to organizational size.Design/methodology/approachCross-border study with experts from multinational enterprises (MNEs) in Austria and small and medium companies (SMEs) in Italy.FindingsWith increasing digitalization, leadership is becoming more important. In times of social distance, it is essential that leaders actively foster the management of relationships with their employees, manage social processes in their teams and shape change processes. This requires a bundle of skills consisting of effective leadership skills, strong change management skills and conceptual digitization skills.Practical implicationsDigital transformation is not mainly about implementing new technologies; it is about developing an appropriate strategy in which people are key. Organizations regardless of size need to recognize that digital transformation requires not less, but even more active shaping of the relationships between leaders and their team members. Consequently, they need active leaders who drive, communicate and implement technological change. As leadership and change require time, resources and, above all, attention, executive selection and qualification are critical for the broad integration of digitalization ideas into an organization.Originality/valuePeople, not technology, drive digital transformation, and organizations require leaders, not necessarily technological specialists, to manage the complex changes that comprise an organization’s digital transformation. Technical and methodological skills can be substituted with the use of new technologies, but leaders’ interactional, social, strategic and conceptual skills are gaining in importance.
Dynamic association of economic policy uncertainty with oil, stock and gold: a wavelet-based approach
Authors: Soni Rajat Kumar , Nandan Tanuj , Chatnani Niti Nandini 
Published: January 2023

PurposeThis research unfolds a holistic association between economic policy uncertainty (EPU) and three important markets (oil, stock and gold) in the Indian context. To do same, the current study uses the monthly dataset of each variable spanning from November 2005 to March 2022.Design/methodology/approachThe authors have portrayed the wavelet-based coherence, correlation and covariance plots to explore the interaction between EPU and markets' behavior. Then, a wavelet-based quantile on quantile regression model and wavelet-based Granger causality has been applied to examine the cause-and-effect relation and causality between the EPU and markets.FindingsThe authors’ findings report that the Indian crude oil buyers do not need to consider Indian EPU while negotiating the oil deals in the short term and medium term. However, in case of the long-term persistence of uncertainty, it becomes difficult for a buyer to negotiate oil deals at cheap rates. EPU causes unfavorable fluctuation in the stock market because macroeconomic decisions have a substantial impact on it. The authors have also found that gold is a gauge for economic imbalances and an accurate observer of inflation resulting from uncertainty, showing a safe haven attribute.Originality/valueThe authors’ work is original in two aspects. First, their study solely focused on the Indian economy to investigate the impact and causal power of Indian EPU on three major components of the Indian economy: oil, stock and gold. Second, they will provide their findings after analyzing data at a very microlevel using a wavelet-based quantile on quantile and wavelet-based Granger causality.
Green libraries: barriers to concept development
Authors: Fedorowicz-Kruszewska Małgorzata 
Published: January 2023

PurposeThe library community is considerably active in environmental issues, but the body of scientific and professional literature in the library and information science (LIS) related to environmental issues is growing slowly. The author attempts to indicate the reasons for the still-low interest in the issue of green libraries on a global scale by pointing to barriers in the development of the green libraries concept in both theoretical and practical dimensions.Design/methodology/approachThe desk research method was used in this study.FindingsBarriers to the development of the green libraries concept include an ambiguous definition of green libraries, a lack of guidelines for green libraries, a lack of criteria for evaluating green libraries, insufficient dissemination of the essence and goals of environmental education, a lack of developed tools for monitoring progress towards Sustainable Development Goals (SDGs) in an environmental aspect at a national level and insufficient integration of environmental topics in LIS curricula at the higher-education level.Originality/valueAlthough, since the 1990s, the body of literature on sustainable development from an environmental perspective has been growing, LIS researchers' activities do not reflect the importance of this issue. The originality of the article lies in the indication of the reasons for the still-low interest in environmental issues in LIS literature. To date, this issue has not been discussed in the literature.

Published: January 2023

PurposeOpen access repository is an essential element of an organization's strategy for enhancing the visibility and accessibility of its intellectual output to a global audience. Owing to its importance, the study aims to explore the current status of open access repositories in India and China by analyzing the different characteristic features of repositories.Design/methodology/approachThe data for the study is collected from OpenDoar which is labeled as a quality assured repository directory across the globe. The country-wise contribution of Asian repositories is extracted from OpenDoar using various filtration options available in the repository. Further, the URL of every Indian and Chinese repository was manually accessed to gather the following metadata: Repository Type, Software Usage, Repository Interface Language, Year of Development, Subject Coverage, Content Coverage, and the utilization of Web 2.0 tools by repositories. FindingsThe findings of the study highlights that among the Asian countries, India is at 4th rank while China is at 5th rank in terms of repository count. The study depicts that India has shown more promising growth than China. However, both the countries mainly focused on institutional repositories while disciplinary, aggregated, and governmental repositories are very few in number, therefore building such repositories is the need of an hour. Dspace as the preferred software and English as a dominant interface language occupy the prominent places in the repositories of both countries. Moreover, the repositories of both countries have embraced web 2.0 tools like RSS 1.0, RSS 2.0 and Atom with little presence of social media tools.Research limitations/implicationsThe study has limitations, and results should be interpreted with caution. The comparison between the two countries is based on only one data source, i.e. OpenDoar. However, there is a possibility that future studies can take various repository directories as a data source that will give a clear picture of comparison.Originality/valueThe study can be beneficial to the policymakers and the administrators of these two regions as it will provide them a vivid picture of the diffrent characteristic features of their repositories so that they can formulate better policies that will be helpful to foster green open access.
Fostering strategic entrepreneurship of SMEs: the role of organisational change forces
Authors: Luu Tien Dung 
Published: January 2023

PurposeStrategic entrepreneurship (SE) exemplifies the interconnection of strategic management and entrepreneurship, inferring that organisations could yield tremendous wealth by synchronously pursuing advantage- and opportunity-seeking behaviour. This study examines how small and medium-sized enterprises (SMEs) thrive SE by leveraging organisational change forces.Design/methodology/approachThis study uses a covariance-based structural equation model (CB-SEM) based on 477 key role employees in 95 import and export SMEs in Vietnam.FindingsSE in SMEs requires organisational change forces, namely leadership, employee engagement and buffering foundation of adaptive culture (AC). In particular, transformational leadership (TL) is beneficial and significantly influences SE behaviour via the mediating role of organisational change commitment. In addition, the adaptable culture of SMEs can serve as a buffer, allowing TL concepts to permeate and transfer to administrative bodies, thereby encouraging SE.Practical implicationsThis paper describes why and how SME leaders can make decisions and manage SE to generate a comparative edge. Leaders must understand and assess organisational change forces that play a crucial role in thriving SE, which must pay considerable attention to employees' commitment to change and create an AC.Originality/valueThe findings indicate that achieving SE in SMEs requires a blend of core organisational change forces, such as leadership, cohesive employees and an environment that facilitates adaptation.

Authors: Yadav Supriya , Singh Kulwant , Gupta Anmol , Kumar Mahesh , Sharma Niti Nipun , Akhtar Jamil 
Published: January 2023

Purpose
The purpose of this paper is to predict a suitable paper substrate which has high capillary pressure with the tendency of subsequent fluid wrenching in onward direction for the fabrication of microfluidics device application.

Design/methodology/approach
The experiment has been done on the WhatmanTM grade 1, WhatmanTM chromatography and nitrocellulose paper samples which are made by GE Healthcare Life Sciences. The structural characterization of paper samples for surface properties has been done by scanning electron microscope and ImageJ software. Identification of functional groups on the surface of samples has been done by Fourier transform infrared analysis. A finite elemental analysis has also been performed by using the “Multiphase Flow in Porous Media” module of the COMSOL Multiphysics tool which combines Darcy’s law and Phase Transport in Porous Media interface.

Findings
Experimentally, it has been concluded that the paper substrate for flexible microfluidic device application must have large number of internal (intra- and interfiber) pores with fewer void spaces (external pores) that have high capillary pressure to propel the fluid in onward direction with narrow paper fiber channel.

Originality/value
Surface structure has a dynamic impact in paper substrate utilization in multiple applications such as paper manufacturing, printing process and microfluidics applications.
