Published: November 2024

Purpose
Corrosion of steel in marine environments poses a significant economic and environmental challenge because of its detrimental effects on marine structures and equipment. Traditional chemical inhibitors that mitigate corrosion often introduce harmful substances into the environment. As a result, there is a growing interest in exploring eco-friendly alternatives, such as plant-derived inhibitors, to reduce the environmental impact of corrosion protection strategies. The purpose of this study is to investigate the effectiveness of Phyllanthus urinaria extract as a green anti-corrosion additive for rebar steel in marine conditions.

Design/methodology/approach
Phyllanthus urinaria extract was prepared in the ethanol solution with the assistance of a sonicator. The steel’s surface upon addition of the extract was characterized using SEM, EDX and FTIR analysis. The electrochemical corrosion characteristics, including potentiodynamic polarization and electrochemical impedance spectroscopy, were used to evaluate the inhibitory performance of the extract on steel under simulated marine conditions (3.5% NaCl solutions).

Findings
The results of this study showed that with Phyllanthus urinaria extract’s content of 0.02% in NaCl solution of 3.5%, the corrosion rate decreased to about 30% compared to the controlled sample. Measurements of the inhibitory mechanism analysis study for all solutions from 0 mg/L to 1.114 mg/L of polyphenol from Phyllanthus urinaria extract showed a significant reduction in rebar corrosion rate, especially with 0.2228 mg/L polyphenol. Reinforcement can increase corrosion inhibition by up to 30% compared to the control sample.

Originality/value
To the best of the authors’ knowledge, this is the first study of using Phyllanthus urinaria extract as green inhibitor for protection of steel from the corrosion in the simulated marine solution. The protective mechanism for steel using Phyllanthus urinaria extract was investigated using the FTIR, SEM, EDX and electrochemical analysis. The results indicated that the polyphenols in the extract showed inhibition that could minimize the corrosion of reinforcement in marine environments.
How far can I trust you? Understanding the social identity perspective of trust development in global virtual teams
Authors: Mumtaz Sana , Nadeem Sadia 
Published: November 2024

PurposeNew technologies, digitalization tools, and the changing world of work have created a virtual, multicultural, and crossborder environment within organizations. Consequently, a growing body of international business literature is focusing on global virtual teams. However, the research so far has focused more on work-based challenges and outcomes of global virtual teams, with limited attention to long-term trust development between members in these teams. This gap is the key focus of the present research.Design/methodology/approachIn this study, data were collected from 19 interviewees of various nationalities who were part of global virtual teams to understand trust development and identity changes. Afterwards, the NVivo software was used, and findings were generated using the “thematic analysis approach.”FindingsThe findings suggested that individuals working in global virtual teams perceived that such a work arrangement had a positive effect on their work performance; however, it had several negative consequences for their social and nonwork lives. Further, while many team members were able to develop swift and cognitive trust with their global virtual team members, the development of affective trust was less common. Also, exposure to multicultural team members, albeit remotely, resulted in most of the individuals embracing (perceived positive) changes in their behaviors and attitudes, thus reflecting a gradual move toward globalization of the workforce values, yet simultaneously creating greater uncertainty and complexity in their identity and work values.Originality/valueUsing the findings, a novel process model, i.e. “the social identity perspective of trust development in global virtual teams” has been proposed, which offers a step-wise guidance regarding how affect-based trust may be developed in global virtual teams in various stages.
Evaluation for digital transformation capability of construction enterprises: a case study in China

Published: November 2024

PurposeWith the development of a new generation of digital technologies, digital transformation (DT) has become an inevitable trend for enterprises to achieve development in various industries. Nevertheless, the contradiction between the “fragmented” use of digital technologies and the “systematic” transformation of the industry leads to the underperformance of DT in the construction industry. Whilst previous studies have examined why DT is needed and how separate digital technologies can be used in construction projects, they failed to specify effective tools that can help enterprises identify key resources that facilitate DT from the organisational perspective.Design/methodology/approachThis study established an objective assessment framework for evaluating the digital transformation capability (DTC) of construction enterprises in identifying limitations in their transformation efforts. This study also established a management entropy quantitative model and a comprehensive capability evaluation model of DT to analyse the DT performance of construction enterprises from the internal and external perspectives. Data were collected from 95 listed enterprises in China’s construction industry in 2020 as a case study.FindingsThis study concluded that enterprise profitability provides a strong endogenous driving force for DT. Research and development capabilities and DT proficiency of enterprises are the most critical factors in facilitating DT. In addition, China’s construction enterprises' DT was characterised by uneven development and low orderliness. The lack of a unified digital integration platform is key to cracking the dilemma.Originality/valueThis paper systematically identified key DTC in construction enterprises and proposed an objective framework for measuring DTC to enhance the DT performance of these enterprises.

Published: November 2024

PurposeInspired by the neoclassical economic theory and endogenous growth theories, where former studies suggest that the economic growth of a country can be observed through the combination of three factors. Those three factors include capital, the number of labour forces (human capital) and technology. This research was initiated to study the impact of technical and vocational education and training (TVET) sector on the socioeconomic and employment growth of TVET trainers in Pakistan, which is also supporting the Sustainable Development Goals (SDGs).Design/methodology/approachIn this study, quantitative research methods and survey research design have been used. Data were collected using an adapted survey questionnaire from 520 participants. The participants of this study were TVET trainers from different skill-based organizations. Whereas, the collected data was analysed using SPSS 27.0, and the Spearman correlation was used to analyse the relationship and strength of association between the constructs.FindingsFindings of this study indicate that the skill-based education through the TVET sector has a highly positive impact on TVET trainers’ employment, socioeconomic growth of vocational trainers and quality standards of living of the TVET trainers. Whereas, the findings also revealed that this skill-based education has a relatively weak relationship with the traditional content-based education as compared to other targeted variables in the skill development sector which influence the socioeconomic growth of the TVET trainers in Pakistan and similar contexts.Practical implicationsThis study highlights that the TVET has a significant impact on the socioeconomic growth and development of TVET trainers in the context of Pakistan. From the results, international agencies, economists, politicians and policymakers in Pakistan will get some valuable insights to develop policies accordingly which will promote TVET in the country and make a significant contribution to the socioeconomic growth of TVET trainers in particular and the country in general.Social implicationsThis study also promotes the economical sustainability and value creation among vocational education trainers in TVET and skill-based organizations to further strengthen their professional development and growth in Pakistan.Originality/valueThis is one of the few studies which specifies the impact of the skilled-based education and training sector on the socioeconomic growth and development of TVET trainers in Pakistan, particularly in rural contexts or less privileged areas.

Published: November 2024

Purpose We empirically investigate the impact of fintech innovation on dividend payout (DP) decisions. In addition, we also examine the mediated and moderated role of intellectual capital (IC) and board characteristics (BC) respectively in the fintech innovation-DP relationship.Design/methodology/approach Using a sample of 9,441 firm-year observations over the period 2014–2022, we develop a structural model that encompasses fintech innovation, IC, BC and DP decisions. We utilize fixed effects regression to empirically test the model. A battery of tests such as the two-step Generalized Method of Moment, Heckman’s two-stage selection correction and Difference-in-Difference regression are used to check the robustness and sensitivity of the estimates.Findings Our results suggest that fintech innovation significantly and positively impacts DP decisions and IC partially mediates the fintech innovation–DP relationship. In addition, BC such as independence, age and gender diversity are found to moderate this relationship.Originality/value This study’s originality lies in its micro-level analysis of the impact of fintech innovation on DP decisions, considering a novel firm-level innovation metric derived from patent applications. To our knowledge, no previous work has empirically examined the mediating role of IC and the moderating influence of BC in the fintech innovation–DP relationship, offering a unique perspective on the complex interactions shaping dividend policies in the digital era.

The compensatory protective effects of organizational and supervisor support for nurses’ morale in sickness presenteeism: a three-way moderated mediation model
Authors: Wu Hsin-Pei , Lu Luo 
Published: November 2024

PurposeThe present study explored sickness presenteeism as a linchpin connecting prolonged working hours to elevated turnover intention among hospital nurses (mediation). In addition, we examined the joint moderating effects of organizational health care support and supervisor support on the second stage of the “long working hours-presenteeism-turnover” process (three-way moderated mediation).Design/methodology/approachWe conducted a two-wave survey to collect data over a four-month period from hospital nurses in Taiwan. The final sample for analysis had 294 nurses.FindingsWe found that presenteeism partially mediated the elevated turnover intention after working long hours four months later. We also found a significant three-way moderation effect of organizational health care support and supervisor support on the positive relationship between presenteeism and turnover intention. Specifically, nurses reported the lowest turnover intention with high levels of both organizational healthcare and supervisor support, the highest turnover intention with both support being low, and the intermediate level of turnover intention when any one of the support was high.Practical implicationsOrganizations should build a positive work environment through organizational health care support and supervisor support to retain talents.Originality/valueOur findings suggested that support resources of different origins (organization-level vs line supervisor) can compensate for one another to protect the employees in demanding work conditions. Our moderated mediation model exploring the psychosocial context of presenteeism has theoretical contributions pivoting on the interplay of resources at different levels in the organization as well as practical implications for presenteeism management.
Can you develop self-awareness? Only if you are willing
Authors: Rhee Kenneth , Sigler Tracey 
Published: November 2024

PurposeWe examine how leaders can become more self-aware in one graduate program that helped students develop their leadership competencies and become more accurate in their self-assessment of those competencies.Design/methodology/approachThe Master of Science in Executive Leadership and Organizational Change program was created in response to the challenge of developing and accessing leaders in emotional and social intelligence competencies.FindingsThe analysis of student self-assessments and assessments by others at the beginning and end of the program provided the data for our research, showing empirical evidence of leadership development and improvement.Research limitations/implicationsThe study examined students in one program at one university so the generalizability of results is not clear. We have no way to rule out other experiences students had during the two-year period. We chose a single approach to measuring accuracy of self-assessment, future research may compare the results from a variety of approaches to this measurement issue.Practical implicationsWe describe the program that helped students develop leadership competencies, develop the self-awareness necessary to take action as a leader and calibrate a more accurate self-assessment of leadership competencies over a two-year period.Originality/valueWe demonstrate how one leadership development program can help all students become more accurate in their self-assessments. We do not need different development programs to help one group of leaders gain confidence and another for leaders who are overly confident. An educational curriculum can foster transformational learning that enables ongoing leader development (Petriglieri, Wood, & Petriglieri, 2011). Academic programs can create experiences that help students develop and increase their self-awareness so that they are confident enough to put their learning into action. Like effective leadership development programs (Van Velsor, McCauley, Ruderman, & Ruderman, 2010), management education programs can incorporate assessment, feedback and support so that students become the effective and outstanding leaders the world needs.
On the estimation of the switching moment of utility functions in cooperative differential games
Authors: Ye Peichen , Tur Anna , Wu Yilun 
Published: November 2024

PurposeThe purpose of this paper is to emphasize that it is necessary to consider possible “switches” when constructing dynamic models. We consider a class of differential games with switching utility functions.Design/methodology/approachWe assume that the players do not have exact information about the switching moments. The problem is to compute the optimal estimate of the unknown such moment that minimizes the players’ losses in the worst case. Two scenarios are considered: (1) the players have the same estimate and (2) the players have different estimates of the switching moment. An example of an investment problem is given, and optimal controls and trajectories are calculated analytically using Pontryagin’s maximum principle.FindingsThe analysis provides a simple rule for choosing the optimal estimate. It is shown that the players’ optimal estimates are identical in both scenarios.Originality/valueTo date, no research has addressed the optimal estimation of uncertainty switching moments in a two-player differential game involving utility function switching. Our study offers detailed estimates of switching moments in the cooperative case. This allows players to thoroughly evaluate the performance of various estimated switching times and make well-informed conclusions.
Stable isotope analysis indicates partial mycoheterotrophy in arbuscular mycorrhizal woody seedlings in tropical forests
Authors: Zahn Franziska E. , Contreras Blexein , Engelbrecht Bettina M. J. , Gebauer Gerhard 
Published: November 2024

Abstract

Chlorophyllous plants exhibiting partial mycoheterotrophy obtain carbon through mycorrhizal interactions in addition to photosynthesis. In arbuscular mycorrhizal (AM) plants, the Paris‐morphotype (i.e. hyphal coils) is considered essential for mycoheterotrophic carbon gains. Numerous tree species in tropical lowland forests form this morphotype, and under light‐ and nutrient‐limitation, additional carbon gain would be beneficial. However, if seedlings of woody species in the understory of tropical lowland forests exhibit partial mycoheterotrophy remains unexplored.

Here we (a) examined the AM morphotype (Paris‐ or Arum‐type) in seedlings of 41 tropical woody species, and (b) to determine if any of the target Paris‐type species are partially mycoheterotrophic, we compared their multi‐element stable isotope natural abundance (13C, 2H, 18O, 15N) with neighbouring autotrophic non‐Paris‐type reference seedlings.

About 50% of the investigated species (and 80% of the genera) exhibited the Paris‐type, expanding the number of tropical plant genera with Paris‐type AM. Enrichment in 13C, but not in 18O in target compared with neighbouring reference plants indicated partial mycoheterotrophy in seedlings of 6 of the 21 investigated Paris‐type AM species.

Our results indicate for the first time that carbon gain through mycoheterotrophy occurs in seedlings of AM tropical tree species. In tropical forests, partial mycoheterotrophy during seedling establishment may confer so far unrecognised ecological advantages influencing seedling recruitment and ecosystem dynamics.

Citizen science observations shed light on how anthropogenic food sources influence wildlife disease
Authors: Sauer Erin L. 
Published: November 2024

AbstractResearch Highlight: Knutie, S., Bahouth, R., Bertone, M., Webb, C., Mehta, M., Nahom, M., Barta, R., Ghai, S., Love, A., Horan, S., Soldo, A., Cochrane, E., Bartholomew, J., Cowan, E., Bjerke, H., Balenger, S., Butler, M., Cornell, A., Kennedy, A., Rolland, V., Schultz, E., Stanback, M., Taff, C., Albery, G. (2024). Understanding spatiotemporal effects of food supplementation on host–parasite interactions using community‐based science. Journal of Animal Ecology. https://doi.org/10.1111/1365‐2656.14155. Wildlife have become increasingly dependent on anthropogenic food supplementation, resulting in altered nutritional intake and inter‐ and intraspecific interactions. Subsequently, supplemental feeding can affect both the immunological function of individuals and transmission dynamics among individuals and species. The magnitude of the effect supplemental feeding has on disease is likely to vary across time and space with the nutritional demands of hosts. However, the broad temporal or spatial scale effects of supplementation are poorly understood. Recently, Knutie et al. (2024) introduced their citizen science program, the Nest Parasite Community Project, a broadscale coordinated effort by scientists and the public to monitor box nesting wild birds and their ectoparasites across the eastern United States. The authors amassed an impressive 4‐year data set with hundreds of nests spanning the entire US breeding range of Eastern bluebirds (Sialia sialis). In the first study to come from the project, the authors demonstrate that the effects of food supplementation on host–parasite interactions vary across time and space and do not consistently influence host–parasite outcomes, highlighting that host–parasite interactions are often context dependent and influenced by many environmental factors (e.g. weather and habitat quality). The authors also found that supplemental feeding increases host fitness, regardless of parasitism. The study provides strong evidence that citizen science projects can help broaden our understanding of how human food sources influence wildlife disease in various environmental contexts.
