“…The further integration of the artificial intelligence methods to the adopted methodology for investigation of centrality and coordination association is an ongoing study of the authors. The findings of this study are in line with the findings of Freeman, et al (1979/80); Hossain et al (2006) and Hossain (2009) that network centrality position has an effect on coordination. These findings also support the power of social networks in affecting design and construction project actors' coordinative interactions.…”

“…These findings also support the power of social networks in affecting design and construction project actors' coordinative interactions. This study extended the work of Hossain et al (2006) and Hossain (2009) with empirical evidence to show that out-centrality measures define coordination process better than in-centrality measures. Consequently, the study supports that centrally positioned actors in design and construction projects demonstrate greater coordination performance than other project actors within the network.…”

“…Recently, hybrid approaches suggested connecting social network theory with building information modeling (BIM) practice (Taylor and Bernstein, 2009). Centrality and coordination correlation widely discussed in social, math and physics studies (Freeman, et al, 1979/80;Latora and Marchiori, 2007); however the construction domain lacks such discussion apart from primary works of Hossain et al, (2006), andHossain (2009). This study further tests the centrality and coordination association in design and construction projects.…”

“…Malone and Crowston (1994) characterize four different kinds of dependencies and identify the coordination processes that can be used to manage them. Although coordination is abstract and difficult to quantify, Hossain et al (2006) and Hossain (2009) measured coordination depending on the effectiveness of key coordination processes defined by Malone and Crowston (1994). Measurements are taken as (1) the actor's ability to effectively coordinate scarce resources and to maximize their impact, (2) the actor's ability to manage the producer/consumer relationships via transfer of information between other actors of the network, (3) the actor's ability to manage simultaneity constraints setting up task synchronization between actors, (4) the actor's ability to manage tasks/subtasks effectively for achieving higher-level objectives.…”

Coordination is integral to operational efficiency of construction projects. Coordination process relies on managing dependent activities and the structural centrality in social networks is strategic to project actor's management activity. This study aims to explore the effects of network centrality on coordination performance. Network centrality concepts and coordination theory are examined via e-mail communication data of İstanbul Sabiha Gökçen International Airport's (ISGIA) New Terminal Building Wayfinding and Signage Design Project (WSDP) actors. E-mail data mining for identifying different coordination dependencies is derived from the constructs of Malone's (1988) coordination theory and used to measure the actors' coordination scores. Social network matrix of information exchange network is constructed to calculate degree, betweenness and closeness centrality measures. ISGIA data analysis suggests a significant relationship between out-degree, outcloseness centrality and coordination. Findings highlight that out-network centralities support the ability of an actor to coordinate the dependent actions of other project actors; and the design and construction practices rely on the central position in a network in mapping effective coordination processes. INTRODUCTIONBuilding design and construction represent a collective effort from project participants. A construction project involves diverse participants essentially collaborating closely. They are usually geographically separated when making interdependent decisions. This requires coordination to maintain compatibility. Coordination refers to specific protocols and procedures in conjunction with smooth flow of communication in all directions to achieve project objectives (Chitkara, 1998). Technical interdependency and organizational independency of construction projects demand improvement of coordination process to facilitate the efficient information flow and thus product quality (Saram and Ahmed, 2001;Mokhtar et al., 1998). Research that was made on critical success factors identified the efficiency of information exchange as a key factor in delivering high-performance projects (Chan, et. al., 2004). Project performance depends mainly on the effectiveness of coordination process results in communication networks rather than traditional benchmarks for the common factors of time, cost, and quality (Chinowsky, et al.,

Evaluation of coordination performance in a project network requires reliable measures and monitoring methods for effective management. Recent literature includes studies addressing the relationship between coordinative activity and the configuration of communication networks. In these works, the role of network centrality is investigated through the basic standard centrality measures of degree, betweenness and closeness. Current social network analysis research emphasizes new formulations of centrality measures for robust structural analysis of project networks. This paper presents a novel approach for measuring network centrality using the concept of information centrality. It is based on the idea that all paths carry information. The significance of information centrality values for the actors in a wayfinding signage project at Istanbul Sabiha Gokcen International Airport is investigated. A centrality index is defined for each firm based on the average of the four measures of centrality. Findings suggest the existence of a high correlation between coordination scores and the centrality indices. A centrality index augmented by information centrality measure has potentials for assessing the coordination performance in construction management research, and it is promising for the structural analysis of project communication networks.

Introduction: Effective teamwork in paediatric cardiacsurgery is known to improve team performance and surgical outcomes. However, teamwork in low-and middle-income countries (LMICs), including Mongolia, is understudied.We examined multiple dimensions of teamwork to inform a team-based training programme to strengthen paediatric cardiac surgical care in Mongolia.Methods: We used a mixed-methods approach, combining social network analysis and in-depth interviews with medical staff, to explore the structure, process, quality, and context of teamwork at a single medical centre. We conceptualised the team's structure based on communication frequency among the members (n = 24) and explored the process, quality, and context of teamwork via in-depth interviews with select medical staff (n = 9).Results: The team structure was highly dense and decentralised, but the intensive care unit nurses showed high betweenness-centrality. In the quality and process domain of teamwork, we did not find a regular joint decision-making
