Background: For asymptomatic individuals with a singleton pregnancy and a short cervix, vaginal progesterone significantly decreases the risk of PTB and improves perinatal outcomes. Cervical pessary is another option that has been evaluated with inconclusive results. There is, however, a lack of head-to-head comparisons between pessary and vaginal progesterone in this high risk population., Objective: This randomized controlled trial (RCT) aims to compare the effectiveness of pessary and vaginal progesterone for the prevention of PTB in individuals with a singleton pregnancy and a CL ≤25 mm., Study Design: We conducted an open-label, multi-center, RCT (NCT04300322) at 3 hospitals in Vietnam. Asymptomatic individuals with a singleton pregnancy and a CL ≤25 mm (at 16-22 weeks) were randomized (1:1 ratio) to receive either an Arabin cervical pessary or 200-mg vaginal progesterone daily. Primary outcome was PTB <37 weeks of any cause. Secondary outcomes were maternal and neonatal complications. We planned to recruit 804 women to assess a 10% absolute risk reduction in PTB <37 weeks (alpha-error 0.05, power 80%, 5% lost to follow-up). In view of the potential harm of pessary on perinatal mortality and PTB <28 weeks reported recently in 2 recent trials, our study was halted on June 2023. Analysis was by intention-to-treat., Results: Between May 2020 and May 2023, we randomized 301 participants to pessary (N=150) or vaginal progesterone (N=151). Seven participants withdrew consent and 13 were lost to follow-up, resulting in 281 participants available for analysis (pessary group N=139; vaginal progesterone group N=142). The primary outcome, any PTB <37 weeks rate, occurred in 15.1% in the pessary group vs 14.1% in the vaginal progesterone group (RR 1.07; 95% CI, 0.61-1.9). PTB <28 weeks and perinatal death rates were higher in the pessary group, although these differences did not reach statistical significance (7.9% vs 4.2%, RR 1.87; 95% CI, 0.71%-4.9% and 4.3% vs 2.8%, RR 1.5; 95% CI, 0.34-9.2; respectively). Vaginal discharge was significantly more frequent in the pessary group., Conclusion: In this prematurely halted RCT involving individuals with a singleton pregnancy and a CL ≤25 mm, the use of cervical pessary was not found to be superior to vaginal progesterone in preventing preterm birth before 37 weeks. However, vaginal progesterone was associated with nonsignificantly lower rates of PTB <34, <28 weeks, and perinatal death. Our findings, along with other curent evidence, suggest that vaginal progesterone should be preferred over pessary for PTB prevention in individuals with a singleton pregnancy and a short cervix., (Copyright © 2024 Elsevier Inc.

Drawing on the social practice theory, theory of planned behavior, social contagion theory, and social exchange theory, this study focused on tourist behaviors affecting tourism social sustainability and their drivers. Besides its unique contribution to distinguishing positive behaviors from negative ones, this study is the first exploring tourism social sustainability in remote communities in Vietnam, an emerging country and focusing on domestic tourists. The study reveals that tourists' knowledge about tourism social sustainability is not only the safeguard against conducting improper behaviors. Behaviors negatively impacting tourism social sustainability can be instigated by crowd, pampering of one's convenience, and superiority feeling. Furthermore, inappropriate behaviors can be nurtured by the community and service providers. This study also indicates a mixed finding regarding the role of tour operators and tour guides in enforcing the code of conduct and regulations; however, both leader and members of the community can play a critical role in promoting socially sustainable tourist behaviors., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2023 Published by Elsevier Ltd.)

Whistleblowers have significantly shaped the state of contemporary society; in this context, this research sheds light on a persistently neglected research area: what are the key determinants of whistleblowing within government agencies? Taking a unique methodological approach, we combine evidence from two pieces of fieldwork, conducted using both primary and secondary data from the US and Indonesia. In Study 1, we use a large-scale survey conducted by the US Merit Systems Protection Board (MSPB). Additional tests are conducted in Study 1, making comparisons between those who have and those who do not have whistleblowing experience. In Study 2, we replicate the survey conducted by the MSPB, using empirical data collected in Indonesia. We find a mixture of corroboration of previous results and unexpected findings between the two samples (US and Indonesia). The most relevant result is that perceived organizational protection has a significant positive effect on whistleblowing intention in the US sample, but a similar result was not found in the Indonesian sample. We argue that this difference is potentially due to the weakness of whistleblowing protection in Indonesia, which opens avenues for further understanding the role of societal cultures in protecting whistleblowers around the globe., Supplementary Information: The online version contains supplementary material available at 10.1007/s10551-022-05089-y., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© The Author(s) 2022, corrected publication 2022.)

This research aims to understand the link between perceived innovativeness and customer satisfaction in the fine-dining catering segment. By employing a mixed-method approach, this paper proposes a multidimensional framework for measuring the perceived innovativeness of restaurants throughout the entire customer journey. Customer satisfaction was measured by considering online customer-generated data from TripAdvisor. The study not only finds a strong correlation between perceived innovativeness and customer satisfaction but also presents how fine-dining restaurants can employ user-generated data to co-innovate entire customer journeys and restaurant experiences. The results highlight menu-, service-, and customer experience-related innovativeness as the three most important criteria for fine-dining restaurant customers. Additionally, the results of the qualitative study indicate that in the context of fine-dining catering, the quality of the dishes, the service, and the customers' experience with the service staff and chefs are the main elements of satisfaction that restaurants should consider in promoting innovation., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Employees in the hotel industry are among the most vulnerable groups that have been severely affected by the COVID-19 pandemic. Anchored on the general strain theory, transactional theory of stress and coping, and theory of justice, this study investigates the mechanism through which hotel employees' perceived job insecurity affects their deviant work behavior during the COVID-19 pandemic. A survey method was used to collect three-wave sample data from 988 hotel employees in popular tourist destinations in Vietnam. Multivariate data analysis reveals a positive relationship between perceived job insecurity and deviant work behavior, and this relationship is mediated by psychological distress. Furthermore, abusive supervision positively moderates the association between psychological distress-deviant work behavior and the indirect influence of perceived job insecurity on deviant work behavior through psychological distress. These findings are useful for hotel managers seeking to manage and develop employees in a global health crisis such as COVID-19., Competing Interests: None., (© 2022 Elsevier Ltd.

While insight into consumer brand engagement, experience, and identification is rapidly developing, little remains known regarding the association of these, and related, concepts, as therefore explored in this article. Drawing on social identity theory and service-dominant-logic, this study develops and tests a model that explores the effect of customers' brand credibility, -value congruence, and -experience on their brand identification, and its subsequent effect on their brand advocacy, -attachment, and -loyalty. We also examine the potentially moderating role of consumers' engagement in affecting these relationships. To explore these issues, we collected tourist-based survey data. To analyze the data, we used confirmatory factor analysis, followed by structural equation modeling. The findings reveal that brand value congruence, credibility, and experience exercise significant positive effects on customers' brand identification, which, in turn, impact their brand advocacy, attachment, and loyalty. Further, brand engagement is shown to moderate the association of these factors. We conclude by outlining key theoretical/practical implications that arise from this research., Competing Interests: There is no conflict of interest., (© 2022 John Wiley & Sons Ltd.)

The COVID-19 pandemic clearly has various detrimental psychological effects on people's mental health, emphasizing the importance of mindfulness in overcoming such repercussions. This is in line with the growing number of studies that have been conducted to assess the effects of mindfulness in diverse settings. However, the role of mindfulness in reducing mental health issues among university students has received little attention. Therefore, the current work seeks to investigate how mindfulness could reduce the anxiety, depression, and stress of university students and how self-compassion and psychological well-being could mediate the links between mindfulness and these mental health disorders. To that end, an explanatory sequential mixed-method design was adopted. Quantitative data collected, through a two-wave survey, from 560 Vietnamese students having an average age of 18.7 years were used to test the hypotheses. To measure the six variables in the research models, we opted for the Five Facet Mindfulness Questionnaire (FFMQ), Self-Compassion Scale (SCS-26), Depression Anxiety Stress Scale (DASS-21-7 items for each subscale), and World Health Organization-Five Well-Being Index (WHO-5). Additionally, qualitative data from 19 in-depth interviews were utilized to explain the quantitative findings and explore students' experiences in practicing mindfulness and self-compassion to decrease stress, depression, and anxiety. The results elucidated that self-compassion and psychological well-being serially mediated the relationships between mindfulness (as a predictor) and anxiety, stress, and depression (as outcome variables). The findings demonstrated the key role of mindfulness in increasing students' self-compassion and psychological well-being as well as reducing anxiety, depression, and stress. This research holds substantial contributions by providing universities and psychotherapists with recommendations to deal with negative psychological consequences caused by COVID-19., Competing Interests: Conflict of InterestThe authors have no competing interests to declare that are relevant to the content of this article., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022.)

How do organizations and employees react to the COVID-19 pandemic? Can workplace safety management practices (WSPs) maintain employees' organizational citizenship behavior (OCB) in this time of global health crisis? Can employees' perceptions of the risk associated with COVID-19 and job insecurity mediate the WSPs-OCB relationship? Drawing upon social exchange and protection motivation theories, this research aims to answer such questions. Analyzing the survey data from 501 Vietnamese employees using SmartPLS software, we find that WSPs positively influence the OCB and negatively influence the perceived job insecurity. Furthermore, the perceived risk associated with COVID-19 positively affects perceived job insecurity and OCB. Unexpectedly, in the context of Vietnam, a developing country with a collectivist culture, WSPs increase the employees' perceived risk associated with COVID-19 instead of reducing their fear. Also, employees' perceptions of job insecurity are not statistically correlated with OCB. In addition, we reveal a partial mediating role of the perceived risk associated with COVID-19 in the WSPs-OCB relationship. This research highlights the power of WSPs as well as measures to psychologically reassure employees during the pandemics., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2021 Elsevier Ltd.

Objectives: Theory and prior research suggest that improving self-esteem is a promising way to improve students' academic performance and mental health. This study empirically examines the mediating effect of psychological well-being and positive emotion in the relationships between self-compassion, mindfulness, stress, and self-esteem., Methods: An explanatory sequential mixed-method design was employed. Quantitative data collected through a two-wave survey from 654 Vietnamese students were analyzed to test the hypotheses using SPSS 22.0 and AMOS 24.0. Data from 19 in-depth interviews were used to explain the quantitative findings and explore students' experiences in practicing mindfulness and self-compassion., Results: Findings revealed that psychological well-being and positive emotion fully mediated the relationships between self-compassion, mindfulness, stress, and self-esteem., Conclusions: Results of this study highlight the importance of psychological well-being and positive emotion in the self-compassion, mindfulness, stress, and self-esteem relationship, as well as explain a possible process by which factors help university students achieve and sustain a sense of high self-esteem. Ultimately, this study has identified several potential targets for intervention strategies in mental health, such as mindfulness and self-compassion among university students., Competing Interests: Conflict of InterestThe authors declare no competing interests., (© The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2022, Springer Nature or its licensor holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Ecotourism in national parks of developing countries is increasingly recognised as a promising option to achieve sustainable development goals, regardless, might imply various paradoxical managerial challenges. This paper, therefore, seeks to contribute a methodological framework utilising ES-based social landscape metrics (SLM) to address the potential barriers in managing ecotourism-integrated multi-functional national parks. We present a mixed-method case study in Vietnam's Tram Chim National Park (TCNP), conducted via semi-structural interviews and PGIS with tourists and locals. Multiple key informants, i.e. TCNP's authorities were also interviewed to provide their managerial insights and assist in verifying the PGIS results obtained from the tourists and locals. Via the quantified and mapped SLMs, the study reveals the differences between tourists and locals in terms of how and where they perceive and appreciate the intangible values of TCNP. Through spatial statistics, we reported important spatial correlations (i) between different categories of Ecosystem Services (ES) and (ii) between ES richness and diversity on different TCNP's land covers. As a contribution to the decision-making outlook, we remarked potential areas to expand of ecotourism activities based on the spatial hot and cold spots. This study concludes by highlighting opportunities for future research in expanding on socio-geographical assessments of ES, especially in the fields of ecotourism., (Copyright © 2021 Elsevier Ltd.

This paper presents the dataset of a survey on workplace health and safety training, employees' risk perceptions, behavioral safety compliance, and perceived job insecurity in Vietnam during COVID-19 pandemic. The data were collected through an online questionnaire completed by Vietnamese full-time employees between April and June 2020. Using E-mail, LinkedIn, and Facebook, the online questionnaire was sent to respondents who filled it out voluntarily. A two-wave survey was conducted in order to lessen the common method bias. Totally, we received complete matched data for 732 full-time employees. All data were processed through SPSS 22.0, AMOS 23.0 and Smart PLS 3.0. Besides descriptive statistics, the results of the explanatory factor analysis and the confirmation factor analysis were included in this paper, which may serve as a good reference for future studies., Competing Interests: The research team did not receive financial support from any institutions.

Although environmental training program has become a vital solution to minimize environmental challenges, the existing literature has paid little attention to (1) the connection between environmental training and employee in-role green performance (EIGP), (2) the mediating role of employee environmental commitment in this environmental training-EIGP connection, and (3) the cultural perspective (Western and Local) influences on interrelationships between environmental training, EIGP, and employee environmental commitment. Drawing on the social exchange theory and cultural perspective, a quantitative study based on survey data collected from 301 respondents at hotels in Vietnam was employed to fill these research gaps. Findings reveal that environmental training program is as an important tool to drive EIGP directly, and this environmental training-EIGP relationship is significantly mediated by employee environmental commitment. Interestingly, the study indicates support for our prediction that the mediating role of employee environmental commitment on the environmental training-EIGP link is stronger at hotels managed by Western hospitality companies. However, unexpectedly, cultural influence does not moderate the effect of environmental training on EIGP. Other than theoretical contributions, our study carries important practical implications that can help organizations reduce their carbon footprint. Limitations and further research directions have also been discussed., Competing Interests: Declaration of competing interest None., (Copyright © 2020 Elsevier Ltd. All rights reserved.)
