The purpose of this paper is to describe how emerging open standards are replacing traditional industrial networks. Current industrial Ethernet networks are not interoperable; thus, limiting the potential capabilities for the Industrial Internet of Things (IIoT). There is no forthcoming new generation fieldbus standard to integrate into the IIoT and Industry 4.0 revolution. The open platform communications unified architecture (OPC UA) time-sensitive networking (TSN) is a potential vendor-independent successor technology for the factory network. The OPC UA is a data exchange standard for industrial communication, and TSN is an Institute of Electrical and Electronics Engineers standard for Ethernet that supports real-time behaviour. The merging of these open standard solutions can facilitate cross-vendor interoperability for Industry 4.0 and IIoT products.

A brief review of the history of the fieldbus standards is presented, which highlights the shortcomings for current industrial systems in meeting converged traffic solutions. An experimental system for the OPC UA TSN is described to demonstrate an approach to developing a three-layer factory network system with an emphasis on the field layer.

From the multitude of existing industrial network schemes, there is a convergence pathway in solutions based on TSN Ethernet and OPC UA. At the field level, basic timing measurements in this paper show that the OPC UA TSN can meet the basic critical timing requirements for a fieldbus network.

This paper uniquely focuses on the specific fieldbus standards elements of industrial networks evolution and traces the developments from the early history to the current developing integration in IIoT context.

The recent financial crisis has brought business ethics issues to the forefront. While most colleges have formal training in business ethics, a person’s ethical standards have often developed before college age. This application brief proposes using digital popular media to teach servant-leadership principles to public school adolescents. The purpose is to illustrate the advantage of using secular content from the television series Merlin (Wilkie, 2008) to demonstrate an ethics-based leadership perspective through a medium that is accessible to the virtual/video generation.

This paper investigates if investors consider legal insider trading data while making investment decisions. If any investment decision is based on insider transactions, then it will result in abnormal stock characteristics. The purpose of this paper is to investigate if insider trading affects stock characteristics like price, return and volume. The paper further investigates the effect on stock characteristics after the trade of different types of insiders and the relationship between abnormal return and abnormal volume.

The study uses the event study method to measure the abnormal price, return and volume. Two-stage least square regression is used to investigate the relationship between abnormal return and abnormal volume.

The insider trades affect price, return and volume. The results are identical for both buy and sell transactions. The trades of different types of insiders have diverse effects on stock characteristics. The trades of substantial shareholders give rise to the highest abnormal price and return, whereas the promoters' trades result in the highest abnormal volume. No relationship is detected between abnormal return and volume.

A novel method to calculate the abnormal price is proposed. The effect of trading of all types of insiders on stock characteristics is analyzed. The relationship between abnormal return and abnormal volume, after an insider trade, is investigated.

Social media is becoming more prevalent in the higher education classroom. As part of an ongoing study, the Department of Agricultural Leadership, Education, and Communications at Texas A&M University surveyed leadership students about their perceptions of their level of comfort and frequency of use of social media tools and the advantages and disadvantages that these students perceived when social media was used in the leadership classroom. A total of 79 students were surveyed in two upper level leadership courses. Facebook was the social media tool students were most comfortable with and used most frequently. Advantages included social media helping increase quality and efficiency of communication between students and the instructor, social media as a technological norm, access to class information, ease of collaboration, and stronger social connections between classmates. Disadvantages revolved around issues of use of and access to social media.

Providing leadership education for young men growing up without their father, through a structured curriculum and mentoring program, should enhance their development. To examine this, the authors interviewed adult alumni who participated as adolescents in a cohort-based, sixmonth leadership program. Interviews outlined several key themes: once served by others the young men desired to serve their community, choosing an authentic leadership educator matters, program mentors inspired positive life changes, and the learned leadership lessons transcended the setting and the curriculum. This qualitative project examined the efficacy of a youth leadership development program by interviewing past participants. This research outlined how service to others can inspire more service and that leadership education has the potential to alter lives, and in this case, even save lives.

Qualitative, case study methods were used to examine students’ expectations of and experiences with studying women and leadership. Participants were 48 undergraduate students enrolled in an elective course titled Women and Leadership offered in the Leadership Studies minor curriculum at a liberal arts institution. Students perceived women and leadership as a sensitive subject fraught with potential struggles for learners, but were willing to engage in the subject in pursuit of both meaningful learning and their own utilitarian-oriented leadership development. Their experiences show the potential for transformative learning if the course content, structure, and learning environment are purposefully crafted to enable students to deal with anticipated or experienced struggles and engage in rather than resist the learning experience. The findings have implications for leadership curriculum design, course design, and pedagogy. Although this study focused on undergraduate learners in a traditional college classroom, the implications may also be relevant to a range of leadership educators and learners in various educational contexts both within and outside of academe.

The aim of this study is to investigate the impact of local political uncertainty on the asymmetric cost behavior (i.e. cost stickiness) for listed firms in China.

In this study, the authors manually collect the turnover data of prefecture-city officials as a measure of exogenous fluctuations in political uncertainty and obtain firm-level financial information from the China Stock Market Accounting Research (CSMAR) database. To perform the analysis, the authors augment the traditional cost stickiness model by including the interaction terms of the prefecture-city official turnover, and firm-level and prefecture-city level control variables.

The authors find that political turnover leads to a higher degree of cost stickiness, implying that firms retain slack resources when political uncertainty is high. Moreover, the effect of political turnover on cost stickiness is more pronounced for firms residing in regions with weaker institutional environments, and firms that are privately owned and with smaller size. The authors further provide evidence that policy uncertainty and the threat of losing political connection are two underlying channels. Overall, this study documents that the local political process is an important channel that influences corporate operational decisions.

This study provides the first piece of evidence on the relation between political uncertainty and cost stickiness at the local government level. Moreover, the authors propose and demonstrate two underlying channels through which political uncertainty affects firms' asymmetric cost behavior.

The increase in ownership and use of mobile-based devices among college students creates unique opportunities for faculty to develop highly engaging learning environments. With many educational institutions offering campus-wide Wi-Fi, students have the ability to use their mobile devices, including cell phones, tablets, and laptops for engaging with curriculum, specifically with leadership concepts. One method of engaging students is through the use of mobile-based polling, as an audience response system (ARS). Although most studies on the use of ARS in educational settings include traditional response system methods (e.g., clickers), emerging technologies have fueled interest in mobile-based polling. The purpose of this study was to examine the effects that mobile-based polling has among students of leadership when used as an audience response system. A survey regarding perceptions of mobile-based polling was administered to students enrolled in undergraduate leadership courses with the purpose of understanding its importance on various aspects of student engagement. Results regarding their polling experiences indicated that students became highly engaged on three levels— behaviorally, emotionally, and cognitively. Additionally, survey responses suggested that students viewed mobile-based polling as viable for purposes outside of the classroom. Suggestions for using mobile-based polling for learning leadership concepts are also presented. The authors of this study not only present mobile-based polling as an emerging technology with advantages over traditional clickers, but as a pedagogical approach for increasing student engagement and as a tool for enhancing leadership skills.

Academic advisors are an invaluable and steadfast component of leadership students’ higher education experience (Hunter & White, 2004; Mann, 2020; Museus, 2021; Spratley, 2020). Yet, given the myriad student paths and preferences, advising calls for flexibility, commitment, and personalization. Applying growth mindset and design thinking to the academic advising process in leadership education may help advisors meet the diverse needs of their students, integrating theory and practice. Notably, growth mindset and design thinking are linked to overall motivation, confidence, and problem-solving (Dweck, 2015; Hochanadel & Finamore, 2015; Mann, 2020), allowing students to take ownership over and actively engage with their academic advising experience. Therefore, two advising manuals (i.e., a student manual and a faculty manual) were generated to incorporate growth mindset and design thinking-based approaches to the advising experience within leadership education. The manuals were implemented into various advising situations for data collection and feedback. Findings revealed an overall favorable opinion of the manual and guidance for further implementation within the advising process. The two manuals presented in the current paper provide leadership education students, academic advisors, and departments with various tools to enhance and guide their undergraduate student experience.

This paper aims to examine a two-way interaction between social influencers’ number of followers (micro vs meso) and argument quality (weak vs strong) on consumers’ self-reported and brain responses to advertising posts on Instagram. Further, drawing upon source credibility theory and contemporary theories of persuasion, the Instagram users’ perceptions of the influencer’s credibility are predicted to mediate the hypothesized effects.

Through an online (N = 192) and a lab study (N = 112), the authors examined Instagram users’ responses to an advertising post from Instagram influencers in terms of perceived source credibility and electronic word-of-mouth intention, using validated multi-item scales from existing literatures and electroencephalogram (EEG) measures. The hypotheses were tested with a 2 (type of influencer: micro vs meso) × 2 (argument quality: weak vs strong) between-subject design using mediated moderated linear regression analysis.

The results highlight that meso-influencers are perceived as a credible source of information only when their product-related post provides strong argument quality. Moreover, this process involves an increase in users’ cognitive work (measured with EEG), with possible implications on marketing communication strategies and online message design.

The limitations of the work can serve as ideas for future research. First, this study did not account for the influencer’s relevance and resonance. Second, the authors studied consumer responses to online communication produced by Instagram influencers within a single product category. Another important product type distinction that requires further attention is between hedonic and utilitarian products. Finally, the two studies only used positive review content. Further research should study how consumers evaluate the source credibility of a micro- vs meso-influencer when they are exposed to negative reviews containing weak vs strong arguments.

The results suggest that marketers should carefully consider Instagram influencers based on the trade-offs between credibility and reach. Specifically, micro-influencers are perceived as more credible sources of information than meso-influencers, which means that they have greater potential to affect Instagram users’ behavior. Moreover, the results suggest that meso-influencers should leverage argument quality to enhance their credibility and draw greater positive outcomes for the products and brands they endorse.

To the best of the authors’ knowledge, this study is the first to investigate how the interaction between the type of social media influencer and the argument quality affects consumers’ self-reported and brain responses to advertising posts on Instagram. Moreover, using neuroscience, this study aims to shed light on the neurophysiological processes that drive consumer responses to product-related communication posted by different influencer types.
