Abstract
Purpose
Multiple infectious control measures, e.g. social distancing, city lockdown and mask-wearing, have been implemented since the coronavirus disease 2019 (COVID-19) outbreak. Given the bidirectional relationship between foundational movement skills (FoMS) and physical activity (PA), and inadequate PA in Chinese children and adolescents, FoMS tends to decrease during and after the COVID-19 pandemic. Therefore, the purpose of this paper is to systematically review the literature about the impact of the COVID-19 pandemic on FoMS of individuals aged 5–17 years in Chinese societies.
Design/methodology/approach
Preferred Reporting Items for Systematic Reviews and Meta-Analyses was followed. Peer-reviewed articles on four electronic databases (Scopus, Web of Science, EBSCOhost and PubMed) were searched on 8 May 2024. The quality of each study was evaluated by the Mixed Methods Appraisal Tool (MMAT) version 2018. Two independent reviewers were involved in all study selection and appraising procedures.
Findings
Among 18,450 records identified, 10 quantitative studies analysing student participants were included. The overall quality of these studies was high, with an average score of 86% in MMAT. The variations among these studies led to inconclusive evaluations. So as to advance the quality of future research and assessments, investigating more aspects of FoMS, standardising physical test protocols and report styles and adopting multiple research designs should be achieved.
Originality/value
To the best of the authors’ knowledge, this is the first review synthesising evidence about FoMS for Chinese children and adolescents. A definitive conclusion cannot be provided due to certain methodological issues. The current situation of FoMS and future research directions were illustrated.

Abstract
Purpose
As the companion paper of Part I, this paper aims to get more insight into the essence of lambda and to reveal its nature and role in the transition of lubrication states. Mixed lubrication (ML) model with micro-asperities contacts has been discussed in details in Part I.
Design/methodology/approach
Mimetic algorithm is used to get numerical solutions. Relationships between film thickness ratios and lubrication states transition with different external loads, rotating speeds, radial clearances, elastic modulus, surface hardness and roughness parameters are obtained.
Findings
The characteristic parameters of transitions from boundary lubrication (BL) to ML and ML to hydrodynamic lubrication (HL) are studied to determine how these parameters change with above factors. Finally, the essence and major influencing factors of lambda are summarized for such bearings.
Originality/value
In Part II, the authors believe that the paper presents for the first time: further insight into the essence of the lambda ratio, and its role in the lubrication states transition are given; the determinations of the characteristic parameters of transition from BL to ML and ML to HL are investigated for the first time; the characteristic parameters of transitions from BL to ML and ML to HL are also studied to determine how parameters (external load, rotating speed, radial clearance, elastic modulus, surface hardness and roughness parameter) change with above factors; a summary of the essence and major influencing factors of lambda for such bearings is given.

Abstract
Purpose
This paper aims to provide efficient methods to calculate the friction coefficients and film thickness ratios in mixed lubrication (ML) regime for water lubricated bearings. Mathematical models consider influence of micro-asperities contacts which is based on the Gauss random distribution.
Design/methodology/approach
Effects of external loads, rotating speeds and radial clearances are obtained. Algorithm shown here is applied to a class of common industrial problems. Calculated Stribeck values are given and evaluated. The calculated and experimental results agree well which proves the correctness of the model.
Findings
In Part I, the authors believe that the paper presents the following for the first time: universal methods are developed for the calculation of friction coefficients and film thickness ratios (lambda) in ML regime; effects of different external loads, rotating speeds and radial clearances on friction coefficients and film thickness ratios are presented in detail; comparisons are made between the results predicted by the model and experimental results, and they agree rather well which proves the correctness of the model.
Originality/value
Present work successfully develops universal methods for predicting the friction coefficients and film thickness ratios.

Abstract
Purpose
This study aims to examine the underlying mechanisms through which entrepreneurial marketing (EM) promotes the development of a favorable brand image and enhances sales growth and market share in new ventures (NVs).
Design/methodology/approach
The authors tested the theoretical model using a multi-informant design in which survey data were collected from NV entrepreneurs and marketing managers. Hypotheses were tested using linear regression and PROCESS analysis.
Findings
The authors demonstrate the significance of EM as comprising two NV capabilities – first, the level of complementarity between entrepreneurial orientation (EO) and market orientation (MO) as a dynamic capability, and second, brand management capabilities (BMCs) as an operational capability – in shaping a favorable NV brand image and promoting market performance.
Research limitations/implications
The authors offer a novel perspective by demonstrating that EO and MO yield complementarities in driving NVs’ BMCs, which, in turn, drive brand image development and market performance for NVs. In doing so, the authors demonstrate novel theoretical implications for the relevance of EM to NV branding, which, to date, has received scant attention in the literature.
Practical implications
The authors identify a potential avenue for entrepreneurs and NV managers to mitigate the potential failure rates by simultaneously pursuing a higher level of EO and MO and investing in brand-building activities. Such efforts can help enhance brand image, drive sales growth and foster long-term success.
Originality/value
To the best of the authors’ knowledge, this study is the first to include brand capabilities as an element of EM, examine EM in NV brand image development and identify the role of EM capabilities relevant to NV brand building and market performance simultaneously.

Abstract
Purpose
The purpose of this paper is to examine the factors associated with user satisfaction in the social network sites (SNSs), and to explore the moderating effects of gender on user satisfaction.
Design/methodology/approach
A research model was built upon the expectation disconfirmation model (EDM) with a focus on SNSs specific motivations (i.e. relationship maintenance and entertainment). The model was tested empirically with 221 experienced Facebook users using an online survey.
Findings
The research model explained 40.5 percent of the variance in user satisfaction. In addition, the results showed that entertainment plays a more important role in determining user satisfaction with SNSs for male users, while relationship maintenance is more important in determining user satisfaction with SNSs for female users.
Research limitations/implications
The current study enriched the theoretical understanding of user satisfaction in the context of SNSs. Particularly, perceptions and disconfirmations about the use of SNSs were identified and empirically tested. Furthermore, gender differences in terms of SNSs usage were empirically demonstrated.
Originality/value
The present study is one of the first few studies that attempts to explain user satisfaction with SNSs as well as examine the role of gender with a theoretical foundation. It complements the empirical research in the IS literature that addresses new social communication technologies.

Abstract
Purpose
The Reinforced Concrete(RC) elements are known to perform well during exposure to elevated temperatures. Hence, RC elements are widely used to resist the extreme heat developing from accidental fires and other industrial processes. In both of the scenarios, the RC element is exposed to elevated temperatures. However, the primary differences between the fire and processed temperatures are the rate of temperature increase, mode of exposure and exposure durations. In order to determine the effect of two heating modalities, RC beams were exposed to processed temperatures with slow heating rates and fire with fast heating rates.
Design/methodology/approach
In the present study, RC beam specimens were exposed to 200 °C, to 800 °C temperature at 200 °C intervals for 2 h' duration by adopting two heating modes; Fire and processed temperatures. An electrical furnace with low-temperature increment and a fire furnace with standard time-temperature increment is adapted to expose the RC elements to elevated temperatures.
Findings
It is observed from test results that, the reduction in load-carrying capacity, first crack load, and thermal crack widths of RC beams exposed to 200 °C, and 600 °C temperature at fire is significantly high from the RC beams exposed to the processed temperature having the same maximum temperature. As the exposure temperature increases to 800 °C, the performance of RC beams at all heating modes becomes approximately equal.
Originality/value
In this work, residual performance, and failure modes of RC beams exposed to elevated temperatures were achieved through two different heating modes are presented.

Abstract
Myth is a story of archetypical personas who behave in ways and with motives that we recognize in ourselves. We use myth as a way of reminding ourselves of the relationship between motives, actions, and consequences. Myths can serve either as inspirational or cautionary tales, and sometimes as both. But “myth” can also mean a fabricated story intended to create a false impression, and to achieve storytellers’ ends when they have decided the truth will not suffice. We apply the myth of Cassandra to the millennium-long recorded history of giant tsunamis in Japan. After each of these catastrophes, survivors sought to warn future generations of their recurrences. But, each time, their progeny eventually lost the memory of these lessons, and lost their lives when the next monster wave overwhelmed them. Only when they kept the lessons as living knowledge in everyday life, could they manage to escape from monster tsunamis. In this chapter, we use the myth of Cassandra in conjunction with the myth of Prometheus, the bringer of fire to humankind, as a metaphor for Japan’s growing reliance on nuclear power. Government and utility companies built powerful but inherently dangerous cauldrons in the nation’s disaster-prone landscapes, assuring the public they could control the fire’s fury and defend it against nature’s. As images of atomic bomb victims were still vivid and widely shared in Japan, they had to overcome the public fear of radioactivity by fabricating a “myth of safety.” The nuclear disaster made the public distrust the government and utility companies, which lingers in the process of reconstruction from the disaster. Myths can either reveal hidden truths or mask hidden lies. The Japanese people must now learn to distinguish one from the other.

Abstract
Purpose
The objective of this systematic literature review (SLR) is to explore the current state of research in the field of household finance (HF). This study aims to summarize the existing research to highlight the importance of household finance in a nation’s economy. By exploring all conceptual and applied implications of HF, this study projects directions for future research to develop a comprehensive understanding of the subject.
Design/methodology/approach
This SLR is based on 112 articles published in peer-reviewed journals between 2006 and 2020 (Table 3). The methodology comprises five steps, namely, formulation of research questions, identification of studies, their selection and evaluation, analyses and syntheses and presentation of results.
Findings
The findings of this study show that studies on HF are gradually increasing worldwide with the USA registering the highest number of published research on the topic during the period under scrutiny. Notwithstanding the increasing attention and research on HF, empirical research in emerging economies is lagging. Additionally, this study finds that HF structure presents a perfect setting to understand how households compose their financial portfolio, make financial decisions and what factors influence their decisions.
Research limitations/implications
This study is an SLR – an accurate and accepted method of reviewing available literature on a selected subject. However, the selection of inclusion and exclusion criteria depends on the researchers’ rationale which might lead to research bias. This should be considered an inherent limitation of SLR.
Practical implications
By synthesizing the contents of extant literature, this study presents important insights into HF. This study underlines the most discussed topics in the domain and identifies potential investigation areas. This study gives the knowledge of leading articles, authors and journals and informs scholars and academicians about the areas that need further investigation by portraying the complete picture of the subject in a systematic manner. Further, this study highlights that households make suboptimal financial decisions that affect their financial well-being. To reduce the adverse impacts of these decisions, policymakers and financial institutions must take steps to improve households’ use of formal financial markets. Household decisions can be reformed by enhancing consumers’ knowledge about financial products and services. Furthermore, households can be served better by offering customization in traditional financial products.
Originality/value
This study synthesizes the main findings of selected literature on HF. The expansion of studies on HF has generated the need to review the existing literature in a systematic manner. To the researchers’ best knowledge, this SLR is the first thorough study of available articles in the HF domain. This study presents the scope of future research by highlighting numerous aspects and functions of HF.

Abstract
Purpose
The purpose of this paper is to investigate the influence of employees’ trait rumination on the variability of their state rumination and the continuing influence on their negative affect at home.
Design/methodology/approach
A time-lagged experience sampling method was used for the data collection from full-time employees in the hotel industry. The hypotheses were tested with multilevel modeling using a random coefficient modeling approach.
Findings
Hotel employees who are high in trait rumination generally show high levels of state rumination and greater within-person variability in state rumination over time. Additionally, the negative effects of workplace state rumination can last until employees come home and the next day before going to work. Furthermore, employees who are high in trait rumination are more likely to be influenced by state rumination, as they experience more negative affect after arriving home.
Practical implications
Rumination has been shown to decrease hotel employee overall well-being. The findings of this study provide suggestions for remedial measures that can be taken by hotel organizations to help employees address ruminative thinking.
Originality/value
Drawing on response styles and work/family border theories, this study contributes to the rumination literature by considering both trait rumination and state rumination in a broader context. For a comprehensive understanding of the dynamic temporal characteristics of state rumination, this study considers the net intraindividual variability of state rumination as the outcome of trait rumination.
