To better understand executive communication on social media, the purpose of this paper is to examine the pattern of messages posted by chief executive officers (CEOs) on Twitter and their retweetability (rate of reposting by other users).

The study data comprises 1,068 original tweets randomly selected from all Fortune 1000 CEOs’ tweets in 2014. The impact of the contextual factors (industry background, activeness, and Twitter age) and content factors (content types, supplementary information, and linguistic features) on retweetability was examined through regression analyses.

CEOs tweet to share information and insights, to promote their companies or products, to update work or life status, and to interact with the public. Original insights, promotional messages, and seasonal greetings were most likely to be retweeted. CEOs’ backgrounds, usage of hashtags, and certainty of language were also positively associated with retweetability.

CEOs may enhance their online social influence through demonstrating leadership by sharing insights about their organization or industry and posting topical messages (e.g. season’s greetings). Furthermore, CEOs could use hashtags strategically to initiate or participate in discussions and promote their personal visibility.

This study is one of the first to evaluate how leaders of the largest companies in the USA communicate on Twitter. It contributes to a theoretical understanding of the factors underlying online influence – the influence of the status of the online communicator vs the message content on information forwarding.

This study examines the direct and indirect impact of environmental belief, nature-based destination image and time perspective on tourist attitude towards ecotourism.

Data was collected through a structured questionnaire survey conducted in Vietnam. The dataset consists of 479 valid responses by Vietnamese tourists. Correlation analysis and structural equation modeling (SEM) were used to test the causal relationships among time perspective, environmental belief, nature-based destination and ecotourism attitude. Confirmatory factor analysis (CFA) is conducted to verify the reliability and validity of each latent construct, and to evaluate the discriminant validity, convergent validity, composition reliability and average variance extracted (AVE) for the latent constructs.

This study finds statistically significant and positive effects of time perspective, environmental belief and nature-based destination image on ecotourism attitude. The results also indicate that environmental belief is found to have statistically significant effects both direct and indirect on ecotourism attitude; its indirect effect is transmitted through nature-based destination image. Our findings demonstrate empirically that tourists are mainly attracted by natural environment sites and that tourists having environmental beliefs are likely to engage in ecotourism than other types of tourism by first influencing their attitude.

One limitation is associated with our measurement method, which relies on respondents’ self-ratings of their activities. Second, our study is based on internal consistency assessments for establishing construct reliability and validity, which might be the problem of measurement misspecification in tourism research and hinder us to adequately capture the dynamic nature of the variables and the underlying relationships. Third, the survey is conducted in one specific ecotourism nation like Vietnam, and thus, the findings must also be explained in this case.

Policymakers need to pay careful attention to the planning and conservation of local resources, as well as infrastructure, for ecotourism development. Moreover, the management of eco-site needs to maintain ecology properly, provide an authentic ecotourism experience to improve ecotourism destination. Otherwise, ecotourism operators should focus on marketing strategies to increase traditional and natural values and promote eco-friendly social standards for fostering demand.

This study examines an integrated model analyzing the impact of time perspective, environmental belief and nature-based destination on tourist attitude towards ecotourism. This study reveals the understanding of how individuals’ view towards belief in environment and location image, influences their attitude to engage in ecotourism. The study provides several implications for practice.

The purpose of this paper is to contribute to the extant literature about the co-evolvement of Business Process Management (BPM) and the Internet of Things (IoT) by proposing the IoT-enabled Context-aware BPM (IoT-CaBPM) framework to bridge from the IoT infrastructure to context-aware business processes.

Motivated by the “Three Waves” of BPM research, IoT-enabled context-awareness is, therefore, expected to be achieved for enhancing the business process design, which pilots a new wave of BPR (Business Process Redesign/Reengineering) to enable the business process coevolve with IoT and analytics. This paper reports an illustrative case study of BPR in a Chinese bulk port, one of the hub seaports that widely adopted IoT technologies over the last few years.

The IoT implementation and data analytics has increased the efficiency and improve the monitoring effectively. The proposed IoT-CaBPM framework availably helps to identify and match nodes of IoT devices, business decisions and analytic models in order to redesign a business process towards context-aware variability. As IoT is rapidly becoming the new dominant IT paradigm is moving towards mature implementation in various industries, the corresponding BPR must be planned and executed strategically for achieving better benefits.

Despite some research extend BPM standard by integrating IoT devices as a sort of resources or report generically that the ports operations are affected by IoT, there is still a lack of layers from the IoT infrastructure to context-aware business processes. An industrial BPR case with business models in detail is also a lack for presenting the specific implications and effectiveness of the adoption of such technologies. This paper fills in this gap.

The goal of this research is to investigate the association between transformational leadership style, psychological capital and job attitude (job satisfaction and organization commitment). Transformational leadership's effects on these job attitudes were also analysed in terms of the mediating effects of psychological capital.

The authors received 296 authentic questionnaires from the para-medical staff working in different public and private healthcare institutes in Jammu and Kashmir, India, and these were then analysed by using SEM with SPSS 25.0 and AMOS 19.

Results implied that transformational leadership increased the levels of employees' job attitudes. The results further displayed that transformational leadership and psychological capital in the workplace are positively associated. The results also showed that psychological capital was positively linked with job attitudes. Moreover, psychological capital serves as a mediating construct between transformational leadership and job attitudes.

The outcomes of this research will help in comprehending the significance of transformational leadership and psychological capital. Further, these research findings affirm the effectiveness of transformational leadership and psychological capital in forecasting positive job attitudes in the Indian work context. The administrators and policymakers in the healthcare sector can implement these concepts to reduce negative job outcomes.

This study expanded on Deci et al.’s (2017) existing self-determination theory model by incorporating leadership style and psychological capital as workplace context and autonomous intrinsic factors, respectively, into the self-determination theory model to study work behaviours of job satisfaction and commitment. This study contributes to existing self-determination theory knowledge by proposing and testing psychological capital as a mechanism for determining the effect of transformational leadership on job attitudes (job satisfaction and organizational commitment).

This paper aims to explore the impact of team psychological safety and team learning on the creation of team knowledge. When teams engage in learning, their interactions contribute to improved performance. Very little research evaluates whether the learning also creates new knowledge related to the task or the team itself.

The proposed model is evaluated through a mixed method research design around a team problem-solving experiment. Task- and team-related team mental models are elicited using concept mapping and questionnaires and are measured before and after the experiment. The model is evaluated in engineering teams from the USA and France.

The findings confirm the proposed model; team psychological safety and team learning positively impact team knowledge creation for both task- and team-related knowledge.

This research has theoretical, methodological and practical implications. The team psychological safety model is expanded, team learning is evaluated from the team interactions instead of members’ self-assessments and team knowledge is measured dynamically. Developing team psychological safety and creating team learning opportunities positively impacts the team’s knowledge.

In this chapter, Mousumi De presents the principles and implications of CRT in the context of Asian and Asian American experiences including the perspective, features, strategies, and new directions on how to facilitate the preparation of teacher candidates and work with all teachers to understand the complexity of the Asian and Asian American identity, their racialized experiences, and their sociohistorical, transnational contexts that continue to influence their lived experiences. This chapter highlights the important issues and challenges facing Asians and Asian Americans that have been camouflaged by their stereotypical treatment as model minorities. It also shares the work of many scholars on approaches for promoting diversity and inclusion, such as implementing anti-racist, anti-oppressive, and inclusive history curricula, cultural citizenship education, teaching for social justice, and culturally responsive and culturally sustaining teaching for addressing the marginalization of Asians and Asian Americans.

The purpose of this study is to explore the relationship between leadership styles, psychological capital and job engagement.

Data were collected among knowledge workers working no less than 1 year in three high-tech enterprises in Henan Province, China. The investigation was conducted with the cooperation from the human resource departments of the selected enterprises from August to October 2014. To minimize potential common method bias, the authors adopted a cross-lagged design with a time gap of four months. The statistical methods included descriptive statistics, structural equation modeling (SEM) and bootstrap analysis.

The results showed: leadership styles significantly influenced employees’ psychological capital and work engagement; specifically, transformational and transactional leadership positively predicted employees’ psychological capital and work engagement; compared with transactional leadership, transformational leadership had stronger predictive power to employees’ psychological capital and work engagement; employees’ psychological capital positively predicted their work engagement; and employees’ psychological capital acts as partial mediator between leadership styles and employees’ work engagement.

Although a body of studies have shown that leadership is an important factor influencing employees’ work attitude and outcomes, it is only in recent years that the effect mechanism of leadership becomes a hot subject in organizational behavior and management fields. As for leadership styles, in general, most research concerned transformational leadership, rather than transactional leadership and only a little of research compared the effects of transformational leadership and transactional leadership on employees’ work outcomes. In terms of outcomes of leadership, as noted earlier, the previous research mainly explored job performance, job satisfaction, innovation behavior, job burnout and so on. Regarding the effect of leadership styles on employees’ work engagement, in spite of more and more supportive evidence of the link between transformational leadership and work engagement, few studies examined the relationship between transactional leadership and work engagement. What’s more, to the best of our knowledge, till now, no empirical research has explored the internal mechanism of this effect from the perspective of psychological capital. Therefore, the present study is a breakthrough for the direct model of leadership styles and employees’ engagement, theoretically bridges the research gap and contributes to the existing literature by presenting a new picture of leadership behavior effect mechanism.

This review aims to give a critical view of the wheel/rail high frequency vibration-induced vibration fatigue in railway bogie.

Vibration fatigue of railway bogie arising from the wheel/rail high frequency vibration has become the main concern of railway operators. Previous reviews usually focused on the formation mechanism of wheel/rail high frequency vibration. This paper thus gives a critical review of the vibration fatigue of railway bogie owing to the short-pitch irregularities-induced high frequency vibration, including a brief introduction of short-pitch irregularities, associated high frequency vibration in railway bogie, typical vibration fatigue failure cases of railway bogie and methodologies used for the assessment of vibration fatigue and research gaps.

The results showed that the resulting excitation frequencies of short-pitch irregularity vary substantially due to different track types and formation mechanisms. The axle box-mounted components are much more vulnerable to vibration fatigue compared with other components. The wheel polygonal wear and rail corrugation-induced high frequency vibration is the main driving force of fatigue failure, and the fatigue crack usually initiates from the defect of the weld seam. Vibration spectrum for attachments of railway bogie defined in the standard underestimates the vibration level arising from the short-pitch irregularities. The current investigations on vibration fatigue mainly focus on the methods to improve the accuracy of fatigue damage assessment, and a systematical design method for vibration fatigue remains a huge gap to improve the survival probability when the rail vehicle is subjected to vibration fatigue.

The research can facilitate the development of a new methodology to improve the fatigue life of railway vehicles when subjected to wheel/rail high frequency vibration.

Transformational, charismatic, and related leadership theories play an important role in understanding how leaders motivate better performance. However, these approaches have paid surprisingly little attention to the management of error in organizations. In fact, current studies in transformational leadership tend to define the management of error as one of the negative features of leadership. Preventing error and learning from error is a high profile leadership role in a wide variety of global industries, and therefore, it is important that leadership theories encompass this critical task. We draw on different streams of research to provide a more integrated and positive approach to leadership and the management error. Studies of error management culture provide insights into the organizational systems that are important for responding and learning from error. We discuss how error learning culture can inform the leadership behaviors that will enhance learning from error. We also draw on regulatory focus theory to show how managing error can be differentiated from other leadership activities. The integration of these ideas with current leadership theory provides a more comprehensive framework for understanding the role of leadership when error management is critical. We present this integrated framework and discuss how cultural factors are likely to shape the role of error management in a variety of global contexts.
