“…Seminal research by Zhu et al (2019) highlighted that transformational leadership could reduce silence behavior among project teams. However, the unfavorable effects of team member's silence on PS, especially in mega construction projects remains largely unknown (Ardakani and Nik-Bakht, 2021;Ma and Fu, 2020;Zaman, 2020;Zettna, 2021;Zhu et al, 2019). Importantly, when transformational leadership is nonexistent and mega construction projects are largely controlled by toxic leaders (who display traits such as abusive supervision, authoritarian leadership, self-promotion, narcissism and unpredictability), the project team member's silence (PTMS) becomes easily rooted and reinforced (Ardakani and Nik-Bakht, 2021;Coakley, 2021;Negash and Hassan, 2020;Zhu et al, 2019).…”

PurposeFailures in both followership and leadership become inevitable as mega construction projects are directed and controlled by toxic leaders. Consequently, team member's desire for knowledge hoarding silence is triggered and goal alignment between the leader and team members suddenly fades away to realize success in mega projects. Considering the growing importance of these rarely examined constructs and fragmented literature on toxic leadership (TL), team silence and mega project success (PS) in the global construction industry, the present study aimed to examine the effects of TL and project team member's silence (PTMS) on the success of mega construction projects. Moreover, the mediating influence of PTMS to link TL and mega construction PS has also been explored.Design/methodology/approachDrawing on survey data of 326 project professionals directly associated with mega construction projects worth US$62bn under the China–Pakistan Economic Corridor (CPEC), the conceptual model was tested with covariance-based structural equation modeling (CB-SEM) using Mplus program. Scales were adapted from previous research to measure TL (with its five-dimensions including abusive supervision, authoritarian leadership, self-promotion, narcissism and unpredictability), PS (with its three-dimensions including project management success, project ownership success and project investment success) and project team members' silence. Reflective–formative second order assessments were specifically applied to measure the multi-dimensional nature of TL and PS, respectively.FindingsMplus estimations revealed that TL negatively influences PS, besides forcing a culture of silence among project team members. Interestingly, the relationship between TL and PS is also negatively mediated by the PTMS.Research limitations/implicationsThe present study's findings are derived from data of project professionals (N = 326) to examine success in megaprojects under the CPEC. Hence, these findings may be re-validated through future studies on similar megaprojects (e.g. China's Belt and Road Initiative (BRI) worth US$8tn) that may also be predicated by TL tendencies, silent cultures and high-stakes involved to seize PS.Practical implicationsPolicymakers, construction practitioners and other key stakeholders (e.g. departmental heads/supervisors) can take advantage of this new evidence to better interpret the success paradox in mega projects, and to reduce the spread and long-term damage of TL on team members and eventually create opportunities for PS.Originality/valueThe present study's novelty is manifested within this first empirical evidence on TL that breeds team silence in underperforming mega projects. Notably, present study offers alarming evidence on mega projects that can be easily derailed from success, as they continue to suffer from team silence and TL.

“…Ardakani and Nik-Bakht (2021) employ the Social Network Analysis tool to compare the effectiveness of three procurement methods for megaprojects, namely, unit rate, lump sum and EPC and to evaluate their functional performance. The main objective was to enhance the decision-making selection for the most suitable procurement method for their respective megaproject type to avoid delays and cost overruns.…”

PurposeThis paper aims to present a structured and comprehensive review of relevant works, collected through a systematic methodology and clustered into nine meaningful categories on megaproject management systems and the current requirements for improved industrial megaprojects.Design/methodology/approachThe methodology employed in this paper retrieves relevant works from available online citation indexes that are published in peer-reviewed journals and other reliable sources from 2000 to 2021.FindingsIt has been observed that the literature on megaproject management is still premature and requires further research to understand better the main gaps and effects of large-scale and typically complex megaprojects. Significant improvements are needed towards covering gaps to address the project management system holistically over the entire project life cycle. There are no clear guidelines for achieving a complete and conclusive project management system and enhancing future megaprojects' management capabilities.Originality/valueThis paper provides a clear picture of the existing literature on megaproject management systems, contributing insights for successful megaproject projects. Additionally, the holistic analysis identifies gaps in the body of knowledge, revealing avenues for future research.

“…In studying rural settlements in semi-urbanized areas, factors such as radiation and diffusion of large cities, industrial out-migration from urban areas, population suburbanization, and new town construction as external factors influencing the spatial development of rural settlements have been considered. In contrast, agricultural industrialization, rural nonagriculturalization, rural tourism, and new rural construction are internal factors promoting the spatial evolution of rural settlements [11]. is study investigated the degree of rural-urban integation along with the village land-use patterns.On the other hand, the study in [12] considered political, social, economical, and physical geographic factors to study the evolution of urbanization in Pearl River Delta's urban fringe areas and proposed the planning countermeasures.…”

In bygone days, the way to deal with traditional villages in developing new cities in China was often to overturn them and replace the original environment with the built-up urban environment, causing constructive destruction to the traditions and cultures. According to the new village transformation requirements, the planning and construction of villages must be shaped with their own cultural and humanistic characteristics of the habitat requirements. It does not favor demolishing large constructions by implementing a different environment. A traditional village is an essential spatial framework to retain the “mark” of the local characteristics of the new city. It can be an essential element in shaping the individual characteristics of the village by realizing the diversity of spatial forms and regional cultural connotations of the new village. Therefore, this paper proposes a new village transformation model based on traditional villages’ social, economic, and spatial patterns, combined with a new particle swarm optimization (PSO) algorithm named multi-objective particle swarm optimization (MOPSO). The model transforms the village based on the required optimum resource allocation with the global solution. The experiment shows that the proposed model suits village renovation and modernization. The work is a step toward the advancements and betterment of rural development.
