The effect of leader emotional intelligence on leader-follower chemistry: A study of construction project managers

Extending Nicolini’s (2002) notion of project ‘chemistry’, this paper proposes the development of a ‘leader-follower chemistry’ model associated with the quality of dyadic interpersonal communication in construction projects. The paper focuses on the project manager as leader and attempts to deepen understanding of the effect of a project manager’s Emotional Intelligence (EI) on the quality of interpersonal communication with their followers- being other members of the project team. While a project manager’s EI, with its associated emotional competencies, is often seen as critical in achieving good relationships with members of the project team, it remains a largely understudied concept, particularly in construction projects. Primary data collected using a series of analytical surveys and live observations of site-based projects meetings were used to examine the relationship between a project manager’s emotional competencies, particularly sensitivity and expressiveness, and leader-follower chemistry. Overall, 68 construction professionals participated in the study. The findings suggest that a project manager’s emotional sensitivity and expressiveness (particularly head gestures) may explain variance in the quality of leader-follower chemistry. Based on the empirical evidence in the context of team communication, a leader-follower chemistry model is introduced, which emphasises the importance of leaders’ emotional sensitivity and expressiveness in a leader-follower communication dyad. The model may be particularly salient in complex project networks with a large number of prominent actors

Collective Action for Territorial Identity in Tourism: The Case Study of Two UNESCO Sites

An innovative approach not developed in management and valorisation of tourist destinations yet considers tourism heritage and related territorial identity as a common and brings attention to the implication of the logics of self-organised and self-governed collective action of the common theory applied to territorial governance. The analysis of two case studies of two UNESCO sites is developed: the Cilento, Vallo of Diano and Alburni National Park and the city of Venice. The first represents a case of territorial domain identity characterised by collaborative governance and the second is characterised by uncooperative governance. The theory of commons and self-governed collective action applied to the two cases contributes to the definition of new research pathways and suggests innovative management strategies

A Study of Phytochemistry, Genoprotective Activity, and Antitumor Effects of Extracts of the Selected Lamiaceae Species

This study was designed to evaluate the genoprotective, antigenotoxic, as well as antitumor potential of methanolic, ethanolic, and aqueous extracts of Melissa officinalis, Mentha x piperita, Ocimum basilicum, Rosmarinus officinalis, Salvia officinalis, and Satureja montana (Lamiaceae), in different model systems. The polyphenols in these extracts were quantified both spectrophotometrically and using HPLC-DAD technique, while DPPH assay was used to assess the antioxidant activity. The genoprotective potential was tested on pUC19 Escherichia coli XL1-blue, and the antigenotoxicity on Salmonella typhimurium TA1535/pSK1002 and human lung fibroblasts, while the antitumor activity was assessed on colorectal cancer cells. Rosmarinic acid, quercetin, rutin, and luteolin-7-O-glucoside were among the identified compounds. Methanolic extracts had the best DPPH-scavenging and SOS-inducing activities, while ethanolic extracts exhibited the highest antigenotoxicity. Additionally, all extracts exhibited genoprotective potential on plasmid DNA. The antitumor effect was mediated by modulation of reactive oxygen species (ROS), nitric oxide (NO) production, and exhibition of genotoxic effects on tumor cells, especially with O. basilicum ethanolic extract. Generally, the investigated extracts were able to provide antioxidant protection for the acellular, prokaryotic, and normal human DNA, while also modulating the production of ROS and NO in tumor cells, leading to genotoxicity toward these cells and their decrease in proliferation
