Abstract
Purpose
This paper investigates how (1) a work environment designed to sustain creativity (i.e. through flexible arrangements and elements of the social-organizational work environment) and (2) the amount of enacted work interactions among employees, interpreted as facilitators of new idea generation (i.e. outdegree centrality in instrumental networks), differently impact creativity and work–life balance.
Design/methodology/approach
The authors conducted a quantitative study in a knowledge-intensive multinational company and collected data through a survey on a sample of 207 workers.
Findings
Findings highlight that flexible work arrangements are positively related to increased work–life balance but not to creativity, whereas having access to a social-organizational work environment designed to foster creativity is associated to an increased level of idea generation, but to a reduction in work–life balance. In addition, centrality in instrumental social networks is also associated to a reduction of work–life balance. Findings thus point to a potential trade-off between structures aimed at increasing creativity and initiatives aimed at engendering work–life balance.
Originality/value
The research contributes to the current debate on new organizational practices for innovation and creativity, highlighting their unexpected implications for workers. The research also contributes to the literature on work–life balance by unraveling previously unexplored antecedents, i.e. social networks and the social-organizational work environment designed for creativity.

Abstract
Validation of the Teachers' Sense of Efficacy Scale (TSES) for use with teachers in Macao (SAR) was undertaken to determine its usefulness as a measure of teacher self-efficacy for inclusive education. This paper discusses the results found by analyzing various versions of the TSES and TSES-C in a Chinese format with 200 pre-service teachers in Macao (SAR). Psychometric analyses were undertaken to investigate the validity of the existing scales and the three and two factor solutions. The results indicated a preferred 9-item version that produced improved factor loadings and reliabilities. The use of a relatively quick and short scale to measure such a complex phenomenon as teacher self-efficacy is discussed. Issues are raised regarding generalizability of scales and the impact of culture, demographics, and edifying issues that may impact on the usefulness of such scales.

Abstract
In our studies of daily newspapers and news websites in small and medium-sized cities in Brazil, we view these enterprises as firms endowed with specific strengths and weaknesses reflecting the characteristics of the localities in which they operate. In addition, we use references from urban geography and the industrial economy to investigate their structure, conduct, and performance. This chapter presents our observations about the structure of these firms and the journalistic business in non-metropolitan cities of the State of Rio de Janeiro. The results point to greater consolidation of newspapers, despite their traditional way of operating; the low performance of news websites and their restricted source of revenue; and the existence of a potential regional market little explored by these media.

Abstract
Purpose
This study aims to examine the impact of founder or descendant chief executive officers (CEOs) on the relationship between tax avoidance and firms' future risk. This issue is important because of an ongoing debate about founder and descendant CEOs' impacts, contributions and implications for firms.
Design/methodology/approach
This study uses a sample of publicly listed nonfinancial Indonesian firms in 2012–2019, most of which are family firms and adhere to a two-tier governance system that was understudied in previous studies. The authors use panel-random effect data regression for the statistical analysis.
Findings
The results demonstrate that founder or descendant CEOs do not affect the positive relationship between tax avoidance and firms' future risks.
Research limitations/implications
This research supports the upper-echelon theory, arguing that top management teams affect firms' strategic policies and outcomes.
Practical implications
CEOs play weaker roles in countries with a two-tier governance system than in a one-tier one. Additionally, in relation to Hofstede's cultural dimensions, Indonesia has collective and feminist characteristics that emphasize elements of togetherness and group so that firms reflect the firms' top management teams and not only CEOs.
Originality/value
This research fills a research gap on the role of founder and descendant CEOs in the relationship between tax avoidance and firms' future risks by analyzing firms in Indonesia, a country with a two-tier governance system and collective and feminine cultural characteristics.

Abstract
Purpose
Because of the importance of having enough sleep in life and health, this study aims to determine the effect of vitamin D supplementation on sleep quality and pregnancy symptoms (primary outcomes) and side effects (secondary outcome).
Design/methodology/approach
In this triple-blind randomized controlled clinical trial, 88 pregnant women with gestational age of 8–10 weeks and serum vitamin D concentration less than 30 ng/ml were allocated into vitamin D (n = 44) and control (n = 44) groups by blocked randomization method. The vitamin D group received a 4,000 IU vitamin D pill, and the control group received a placebo pill daily for 18 weeks. Independent t-, Mann–Whitney U and ANCOVA tests were used to analyze the data.
Findings
The post-intervention mean (SD: standard deviation) of total sleep quality score in the vitamin D and placebo group were 1.94 (2.1) and 4.62 (1.71), respectively. According to the Mann–Whitney U test, this difference between the two groups was statistically significant (p < 0.001). The mean (SD) of pregnancy symptoms in the vitamin D and placebo groups was 23.95 (16.07) and 26.62 (13.84), respectively, and there was no significant difference between the two groups based on ANCOVA test (p = 0.56). Considerable side effects were not observed in any groups.
Originality/value
This study was conducted due to the contradictory results of the effect of vitamin D on sleep quality and the high prevalence of sleep disorders and pregnancy symptoms.

Abstract
Purpose
The COVID-19 pandemic has prompted the fast growth of online music festivals. This paper explores how festivalgoers' experience affects their satisfaction and drives their loyalty to re-attend online music festivals in China.
Design/methodology/approach
Based on an understanding of the music festival experience and the characteristics of live-streamed performances, this paper investigates five factors that affect festivalgoers' satisfaction and loyalty, namely the music experience, ambience experience, separation experience, social experience and novelty experience. The relationships between festivalgoers' experience, satisfaction and loyalty are also explored using structural equation modelling techniques.
Findings
The empirical results suggest that four of the above-mentioned five factors of the online music festival experience directly affect festivalgoers' satisfaction and loyalty. The online mode is a rapid adaptation of and preferred alternative to offline music festivals, whilst the creation of the experience, along with satisfaction with and loyalty to the online music festival, are determined by different factors compared to offline modes. Overall festival satisfaction positively enhances the relationship between festivalgoers' experience and loyalty to online music festivals.
Practical implications
This study offers a range of practical and managerial implications for organisers of online music festival, similar activities such as live-streaming concerts and stage performances and hybrid events.
Originality/value
This study explores a phenomenon that has evolved quickly since COVID-19 and will, potentially, have an ongoing and enduring impact on the music festival sector. It differentiates the understanding of festivalgoers' experience in online and offline modes, which is a new addition to the literature. It also enriches the theoretical understanding of the experience of, satisfaction with and loyalty to online music festivals.

This study aims to assess the association of Healthy Eating Index (HEI) with levels of fasting blood sugar (FBS) and lipid profile in normoglycemic and elevated FBS patients.
Abstract
Purpose
This study aims to assess the association of Healthy Eating Index (HEI) with levels of fasting blood sugar (FBS) and lipid profile in normoglycemic and elevated FBS patients.
Design/methodology/approach
This case-control study was conducted on 144 participants, namely, 72 normoglycemic subjects (FBS < 100 mg/dl) and 72 high-glycemic patients (FBS ≥ 100 mg/dl) aged 20–60 years of age, who were selected from the nutrition and diet clinics in Tehran city. The dietary intake was collected by using a validated food frequency questionnaire to determine the HEI score.
Findings
The mean±SD age and body mass index of participants were 47.1 ± 12.7 years and 29.6 ± 6.0 kg/m2, respectively. The median (interquartile range) of HEI scores in the normoglycemic group and the high-glycemia group were 19.34 (15.24–24.31) and 16.53 (13.35–24.07), respectively. In the overall population, the findings of the multi-variable linear regression model indicated a positive association between the HEI score and high-density lipoprotein-cholesterol (HDL-C) (ß = 0.34; 95%CI: 0.05–0.64, P = 0.01). However, there is no significant association between HEI and HDL-C in normoglycemic (ß = 0.19; 95%CI: −0.31, 0.69, P = 0.45) and hyperglycemic subjects (ß = 0.28; 95%CI: −0.10–0.66, P = 0.15). Furthermore, the association of HEI with levels of FBS, triglycerides (TGs) and low-density lipoprotein-cholesterol (LDL-C) was not significant in any of the analyzed groups, including the total population, normoglycemic individuals and hyperglycemic subjects.
Originality/value
This study was the first study to assess the role of HEI and its components with levels of FBS and lipid profile in normoglycemic and hyperglycemic individuals in Iran. The findings suggested that higher adherence to HEI may be associated with an increase in the HDL-C level. However, HEI could not predict FBS, TGs and LDL-C levels in the adult population.
