CORPORATE VENTURE CAPITAL SYNDICATION STRATEGIES: A DYNAMIC NETWORK PERSPECTIVE

2018

Corporate Venture Capital (CVC) syndication is embraced by over 80% of corporates which co-investing the same startups with other corporates create a CVC syndication network. In this paper, we aim at exploring the evolutionary dynamics of the CVC syndication network. Specifically, we address this topic adopting two different perspectives. First, we investigate the architectural evolution of the CVC syndication network examining five dimensions that characterize the evolution of the network structure (i.e. degree distribution, connectivity, clustering, density and degree assortativity). In addition, we study how three network strategies (i.e. prominence, entrepreneurial and relational) evolv…

Manufacturing Cellulosic Fibres for Making Paper: A Historical Perspective

2018

The manufacture of pulp and paper is an important branch of industry worldwide and is based on complex and multidisciplinary technology. The production and modification of cellulosic fibre, which created the foundation for this industrial sector, has had a rich and colourful history. It has gone through many eras and its development has been closely integrated with the growth of our fundamental knowledge of chemistry and other natural sciences. During the last two decades, modern pulp and paper technologies have undergone some significant developments, especially ones involving the creation of a wide range of new options for different feedstock materials. Nevertheless, the fundamental conce…

Architetture dell'industria del cinema in Sicilia

2022

L'interesse del popolo siciliano per il cinema e l'arte cinematografica si manifesta alla fine del XIX secolo quando, nel capoluogo siciliano viene presentato il Kinetoscopio Edison. Una macchina che permetteva di vedere una figura in movimento accostando l'occhio sulla lente di un meccanismo all'interno del quale girava la pellicola. L'anno successivo, il primo spettacolo di Kinefotografo segna l'inizio delle proiezioni di immagini in movimento su uno schermo. L'evento è seguito dall'arrivo del Cinematografo Lumière che sostituisce le proiezioni itineranti allestite nelle piazze, dando impulso alla nascita di sale di proiezione e, successivamente, a impianti architettonici adeguati ad un p…

Palermo. Una città, una visione

2019

The city of Palermo is open towards South West. It is from that directions that all the connections to Europe arrive. Yet the importance of that area has been rarely acknowledged. Marcello Panzarella, architect and professor of architecture has carefully studied that area. Students'work and his own research work span more than a decade. Its outcome is contained in the book, which is also a real urban project for Palermo

Architectural Representation: a Tool for Urban Regeneration : the Colour Plan of Egadi Islands

2018

The Egadi Islands, at the western end of Sicily, preserve a peculiar architectural and environmental heritage. The work of people – related to tuna fishing, stone extraction and agriculture – has created, over time, an exceptional landscape. The nature, colour and texture of the local stone have given shape to a traditional architecture that, today, risks to disappear and to be replaced by new anonymous buildings. Furthermore, the pressure of tourism threatens to damage this delicate balance established, over centuries, between people and environment. Therefore, the Local Administration decided to adopt a Colour Plan to manage the inevitable processes of territorial transformations. The Arc…

Conjectural reconstruction from archive drawings: methodological aspects

2018

The digital reconstruction of architectural projects starting from archive sources is a well established disciplinary application useful for the study and analysis of architecture and its relations with the historical context as well as for the representation of volumes and spaces not visible in the original documents. Given the importance recognized to these operations which inevitably involve processes of hermeneusi we propose methodological guidelines for the drafting a protocol limiting arbitrariness as much as possible. The analysis was carried out on three projects by Giuseppe Damiani Almeyda (Capua 1834 - Palermo 1911), Ernesto Basile (Palermo 1857-1932) and Salvatore Benfratello (Pa…

Covering the Gap for an Effective Energy and Environmental Design of Green Roofs: Contributions from Experimental and Modelling Researches

2021

AbstractGreen roofs are components of the building envelope that have become increasingly popular in urban contexts because other than providing numerous environmental benefits they are also capable of reducing building energy consumption, especially in summer. However, despite all these advantages, green roofs are still affected by some limitations. Specifically, there are some gaps affecting the energy modelling consisting in the absence of a proper database, information (growth stage, leaf area index, and coverage ratio) relative to the different green roof plant species, which technicians could use in case of lack of actual field data to perform energy analysis of buildings equipped wit…

Definition and Assessment of a BAC Factor for Estimating Electrical Consumption of Outdoor Lighting

2018

The BAC factors method was introduced by the international Standard EN 15232 for a rough evaluation of energy savings in buildings obtained thanks to automation. The above standard considers the building's services such as heating, cooling, ventilation and lighting and takes into account automation on the basis of assumed usage profile for the related technical installations. However, the standard does not refer specifically to the automation of outdoor lighting systems such as those serving gardens, entrance walkways and passages around the building and supplied by it. In this paper, the authors propose a method for evaluation an outdoor BAC factor for lighting system considering various s…

Smart city and public lighting

2015

The smart city is increasingly becoming a concept of reference for what concerns the planning and the spatial development of cities. The concept of smart city cannot be easily standardized. It is based on a multi-service and multi-sectorial planning regarding various urban functions (energy, mobility, waste, etc.) and places them under a common denominator: the use of advanced technologies for minimizing resources consumption and simultaneously increase the quality of life of the citizens. This paper aims to give an overview on the concept of smart city and outline what, at present, are the main intervention areas considered at European level. Then the paper focuses on the public lighting t…
