AbstractDifferent forms of life are known to express RNA ligases that catalyse the condensation of a 3’-hydroxy group and a 5’-terminal phosphate of RNA. No such RNA ligases have yet been identified in vertebrates. Here, we report that the hitherto uncharacterised human protein chromosome 12 open reading frame 29 (C12orf29), which we identified by a chemical proteomics approach, is a 5’-3’ RNA ligase. C12orf29 catalyses RNA ligation via auto-AMPylation of a critical lysine residue by using ATP as a cosubstrate and subsequent AMP transfer to the 5’-phosphate of an RNA substrate followed by phosphodiester bond formation. Studies at the cellular level reveal the involvement of C12orf29 in maintaining RNA integrity upon cellular stress induced by reactive oxygen species. These findings highlight the importance of RNA ligation for cellular fitness.
Gyrator-capacitor based modelling and simulation of forward converter
Authors: Koseni Hakan , Yildiz Ali Bekir 
Published: July 2022

Purpose
This paper aims to propose an efficient model for analysis of power electronic circuits with integrated magnetic components.

Design/methodology/approach
The inductance modeling technique is used as the traditional method for analyzing magnetic components. This model is simple and enough to generate for individual components, that is, an inductor and a transformer. However, it becomes difficult to realize this model for the integrated magnetic structures. This paper shows an appropriate model for individual magnetic components as well as integrated magnetic components and its application to magnetically coupled DC–DC converters. Gyrator–capacitor (G–C) modeling offers a unified, reasonable way of understanding the magnetic components commonly met with in power electronics and the other disciplines.

Findings
G–C model allows any electrical and magnetic circuit to be simultaneously simulated with circuit simulators. In this regard, this paper gives a complete simulation model and analysis as an illustrative example. There is no limitation of this paper or future works. The proposed G–C model can be applied to all power electronic circuits having integrated magnetic components.

Originality/value
In the proposed model, the magnetic circuit is converted to a pure electric circuit with capacitors and controlled sources; every winding is replaced with a pair of current controlled voltage sources, namely, a gyrator.
Approaching the field of addictions through the lens of the gender perspective: emerging issues
Authors: Lainas Sotiris , Kouimtsidis Christos 
Published: July 2022

Purpose
Evidence suggests that the percentage of men seeking treatment for substance use disorders and other addictive behaviours is significantly higher than that of women. This fact raises several crucial questions concerning the field of addictions. This paper aims to emphasize to the study of addiction in the light of gender studies and especially in the light of theories of dominant/hegemonic masculinity.

Design/methodology/approach
The perspective of dominant/hegemonic masculinity in the field of addictions raises a number of questions: Can the dominant/hegemonic masculinity perspective contribute to the understanding of the phenomenon of addiction? What are the implications of male-dominated and male-centred treatment services on meeting the needs of other populations? Are androcentric approaches ultimately helpful for heteronormative men? This paper investigates the emerging questions through a critical review of the literature including the disciplines of psychology, sociology and anthropology.

Findings
The perspective of hegemonic masculinity can make an important contribution to the understanding of addiction as it sheds light on a dimension that is not well researched and used in the field of addictions. The influences of the androcentric approach to addiction treatment are significant and pose problems both in accessing and serving the needs of other populations. The androcentric approach to treatment is not helpful for heteronormative men either as there is a risk of not addressing the toxic dimensions of dominant/hegemonic masculinity that are directly linked to the problem of addiction.

Research limitations/implications
This paper poses interesting research questions for further research in the field.

Practical implications
This paper raises important issues for practitioners in the field and at the same time suggests alternative perspectives on the interpretation and treatment of addiction.

Social implications
The gender perspective that should further enrich psychosocial interventions is crucial for the equal access of all people with an addiction problem to appropriate support structures.

Originality/value
Gender studies can make an important contribution to further understanding of addiction problems and to the development of effective practices for dealing with it. The fact that in substance abuse treatment programmes the vast majority of participants are heteronormative men raises a number of concerns. These concerns relate to the extent to which structures are directed at meeting the needs of these men and whether because of this orientation the needs of other populations such as heteronormative women and those who do not meet the norms of heteronormativity are left uncovered. These concerns are linked to broader considerations of the role that dominant/hegemonic masculinity plays in the aetiology of addiction and in creating barriers to help-seeking for heteronormative men themselves.

Authors: Kaupa Stewart 
Published: July 2022

Purpose
This study examines the impact of organizational learning culture as a strategic tool for gaining sustainable competitive advantage in the public sector.

Design/methodology/approach
The study adopted a qualitative research approach whereby data were collected from 150 public sector employees through focus groups and interviews. The study was conducted in Namibia. The data were analyzed through thematic analysis and content analysis techniques.

Findings
The study found that organizational learning culture has a significant contribution toward organizational performance. Through organizational learning employees learn the values and norms of the organization and the industry and align their behaviors to the desired levels. By so doing employees become more motivated and enthusiastic about the organization resulting in higher productivity.

Originality/value
Few studies have been done to uncover the key forces and factors that drive performance in the public sector. Hence the findings from this study will contribute to the literature and assist organizational leaders, management and practitioners in the public sector to put emphasis on creating an organizational learning culture that would motivate employees and lead to the mindset change of public servants.

Employee’s intention to share knowledge: the impacts of learning organization culture and learning goal orientation
Authors: Yoon Seung Won , Park Jong Gyu 
Published: July 2022

PurposeThe purpose of this study is to examine employees' perceived influence of the learning organization culture and learning goal orientation on their knowledge sharing attitude and intention across multiple industries. In connecting these concepts, the researchers incorporated theories of the knowledge-based firm, goal orientation and reasoned action.Design/methodology/approachA survey was used to collect data from a total of 323 responses from eight South Korean organizations to examine the influence of organizational and individual learning factors on employees' knowledge sharing. Structural equation modeling showed that the proposed research model was supported by item internal consistency and model-fits.FindingsResults indicated that employees' learning goal orientation, knowledge sharing attitude and learning organization culture positively influence employees' knowledge sharing intention. This study highlights that those employees are more likely to share knowledge when employees with high learning goal orientation form a positive attitude toward knowledge sharing in a learning supportive culture and structure.Originality/valueThis study added to the literature of learning organizations by identifying a strong positive connection between the learning organization culture and employees' knowledge sharing. The theoretical contribution of this study lies in which the important roles were extended that the learning goal orientation exerts on employee behaviors when they perceive the organization valuing learning.
Does the stock liquidity drive the trade credit of publicly listed firms in Saudi Arabia?
Authors: Bajaher Mohammed , Shawtari Fekri Ali 
Published: July 2022

PurposeThis study aims to examine the influence of stock liquidity on the trade credit of publicly listed companies in Saudi Arabia.Design/methodology/approachIn this study various econometric models were used to test the data of 900 firms listed in Saudi Arabia during the period of 2010–2019.FindingsThe robust results of the various econometric models indicate that firms are more willing to offer trade credit to customers when stock liquidity is greater; however, they are less likely to rely on obtaining more payables from suppliers. The findings further indicate that payables and receivables are indeed related, but not exclusively, in the sense that more payables lead to more receivables. The study also reveals a pattern of persistence in payables and receivables during the period of study.Research limitations/implicationsThe sample of the present study is only made up of Saudi listed companies. Future research could extend the sample of this study taking into account listed firms in the Middle East and North Africa (MENA) region as a whole so as to gain more insights from the entire region including oil-producing and non–oil-producing countries. More studies are needed to further examine the impact of alternative options for credit access and their linkage to stock liquidity. Finally the difference in difference (DiD) method of analysis as quasi experimental method can be another extension of this research.Practical implicationsThe findings would provide implications for managers and investors by recognizing the potential role of stock liquidity in affecting trade credit and understanding the association between the stock liquidity and trade credit. Management of the firms should look for the ways to enhance the stock liquidity of the firms so as to help in reducing the extreme debts usage and therefore, alternative source of funds can be available accordingly. Once the advantage of stock market is identified, firms' managers should search for chances and policies that can promote stock liquidity and hence make use of the advantages of being liquid.Originality/valueThis paper provides new evidence from the emerging market, particularly the Saudi Arabia. The attempt is one of the first in the region to broaden the knowledge about the effects of stock liquidity on trade credit. It provides market participants with insights on the role of stock liquidity in financial flexibility.
Are emerging economies’ credit cycles synchronized? Fresh evidence from time–frequency analysis
Authors: Saini Seema , Kumar Utkarsh , Ahmad Wasim 
Published: July 2022

PurposeTo the best of our knowledge, no study has examined credit cycle synchronizations in the context of emerging economies. Studying the credit cycles synchronization across BRICS (Brazil, Russia, India, China and South Africa) countries is crucial given the magnitude of trade and financial integration among member counties. The enormity of the trade and financial linkages among BRICS countries and growth spillovers from emerging economies to advanced and low-income countries provide the rationale and motivation to study the synchronization of credit cycles across BRICS.Design/methodology/approachThe study investigates the credit cycles coherence across BRICS economies from 1996Q2 to 2020Q4. The synchronization analysis is done using the noval wavelet approach. The analysis examines not only the coherence but also the extent of credit cycle synchronization that varies across frequencies and over time among different pairs of nations.FindingsThe authors find heterogeneity in the credit cycles' synchronization among the member nations. China and India are very much in sync with the other BRICS countries. China's high-frequency credit cycle mostly leads the other countries' credit cycles before the global financial crisis and shows a mix of lead/lag relationships post-financial crisis. Interestingly, most of the time, India's low-frequency credit cycles lead the member countries' credit cycles, and Brazil's low frequency credit cycle lag behind the other BRICS countries' credit cycles, except for Russia. The results are crucial from the macroprudential policymaker's perspective.Research limitations/implicationsThe empirical design is applicable to a similar set of countries and may not directly fit each emerging economy.Practical implicationsThe findings will help understand the marked deepening of trade, technology, investment and financial interdependence across the world. BRICS acronym requires no introduction, but such analysis may help understand the interaction at the monetary policy level.Originality/valueThis is the first study that highlights the need to understand the credit variable interactions for BRICS nations.
Young children’s interest-driven information practices
Authors: Barriage Sarah 
Published: July 2022

PurposeThis study aims to explore young children’s information practices within the context of their individual interests, examining children’s interest-related information activities, challenges encountered and enablers received.Design/methodology/approachParticipants included 18 children between five and seven years of age and their parents. Data were collected using a multi-stage participatory approach. Children shared their experiences via a book discussion, poster activity, participant-generated photography and a photo-elicitation interview. Parents provided information about family demographics and their perceptions of their children’s individual interests, information practices and digital media use via questionnaires. Data were analyzed using the constant comparative method.FindingsYoung children seek information via print and digital objects, other people and experiences, and use information by applying it to their activities and sharing information with others. Challenges to information activities include children’s own capabilities and skills, constraints of information sources and parental restrictions on their activities. Enablers include affordances of technology and parental support.Originality/valueThis study takes a holistic approach to understanding young children’s perspectives of their information activities, examining information use and sharing activities in addition to information seeking.
Home-based workouts in the era of COVID-19 pandemic: the influence of Fitness YouTubers' attributes on intentions to exercise
Authors: Kim Hyung-Min , Kim Minseong , Cho Inje 
Published: July 2022

PurposeHome-based workouts via fitness YouTube channels have become more popular during the pandemic era. However, few studies have examined the role of social media personae related to intention to exercise. The purpose of this study was to investigate the structural relationships between fitness YouTuber attributes: perceived physical attractiveness (PPA), perceived social attractiveness (PSA), perceived similarity (PS), parasocial relationships (PSRs), wishful identification (WI), physical outcome expectations (POEs), and continuous intention to work out with fitness YouTubers (CIWFY).Design/methodology/approachThis study considered fitness YouTube channel viewers as the unit of analysis. An online survey was conducted to empirically develop and test the research model using structural equation modeling (SEM).FindingsThe SEM empirical findings revealed that the PSRs were significantly influenced by PSA, PPA, and PS. Also, WI was significantly affected by PPA and PS. Furthermore, POEs were significantly impacted by PPA and PSRs. POEs affected the CIWFY. Lastly, PSRs and POEs mediated the influence of PSA and PPA on the CIWFY.Originality/valueThe psychological impacts of exercising to online fitness videos in the era of COVID-19, with its untact (no contact) social norms is timely. The study model demonstrated the fitness YouTube viewers' cognitive path from perceptions toward fitness YouTubers' attributes to behavioral intention. To be specific, the current study demonstrated how three attribution types (i.e. PPA, PSA, and PS) of fitness YouTubers affect viewers' PSRs and WI with fitness YouTubers, along with POEs and CIWFY. Along with health practitioners, fitness YouTubers who want to captivate viewers on their channels might need to consider self-attributes from their viewers' standpoint and should build psychological bonding with viewers.
The determinants of unemployment rate in developing economies: does banking system credit matter?
Authors: Azolibe Chukwuebuka Bernard , Dimnwobi Stephen Kelechi , Uzochukwu-Obi Chidiebube Peace 
Published: July 2022

PurposeIn developing countries, banks play a major role by acting as a conduit for the effective mobilization of funds from the surplus sectors of an economy for onward lending to the deficit sectors for productive investments that will in turn increase the level of employment and economic growth. There has being a rising trend in unemployment rate in Nigeria and South Africa and hence, the need for the study to assess the effectiveness of banking system credit in curbing unemployment rate by making a comparative analysis of Nigeria and South Africa covering the period of 1991–2018.Design/methodology/approachThe study employed the unit root test, Johansen cointegration test, vector error correction model and VAR impulse response function in determining the relationship between the variables.FindingsThe major findings revealed that banking system credit matters in curbing unemployment rate in South Africa than in Nigeria. Also, other macroeconomic factors such as lending rate, inflation rate, Government expenditure and population growth were significant enough in influencing unemployment rate in South Africa than in Nigeria. Foreign direct investment was a significant factor in reducing unemployment rate in Nigeria than in South Africa. The cointegration test showed a long-term relationship between the variables in both countries while the speed of adjustment coefficient of the vector error correction model is faster in South Africa than in Nigeria.Originality/valuePrevious empirical studies on the relationship between banking system credit and unemployment rate have focused much on other regions such as Asia and Europe. Thus, the study is unique as it focused on the African region and also made a comparative analysis by testing the Keynesian theory of employment, interest and money on two emerging African economies which are Nigeria and South Africa.
Rewards and knowledge sharing in the CoPS development context: the moderating role of transformational leadership
Authors: Zhao Ruxiang , Feng Nanping , Wei Fenfen , Wang Youying 
Published: July 2022

Purpose
Knowledge sharing (KS) among employees is critical to successfully developing complex products and systems (CoPS) but is often hampered by employees’ low motivations. The purpose of this study is to investigate how extrinsic and intrinsic rewards influence employees’ explicit knowledge sharing (EKS) and tacit knowledge sharing (TKS) in the CoPS development context. This study also examines the moderating effects of transformational leadership on the relationships between two types of rewards and two types of KS.

Design/methodology/approach
This study builds a research model based on expectancy value theory and Maslow’s hierarchy of needs. To test hypotheses, the authors surveyed 257 employees in CoPS projects and analyzed data with the partial least squares structural equation modeling and hierarchical linear modeling.

Findings
The results of this study demonstrate that extrinsic rewards exert no effect on EKS but negatively affect TKS, while intrinsic rewards significantly promote both EKS and TKS. Moreover, transformational leadership positively moderates the abovementioned relationships.

Originality/value
This study extends the research scenario of KS motivations and responds to the call for shedding light on contextual factors influencing KS. This study also offers a comprehensive theoretical perspective to understand KS motivations. Practically, this study provides managers with suggestions about how to use different rewards to encourage different KS practices.
