Indagini multidisciplinari e ricostruzione virtuale: il caso di studio del Teatro Nord di Hierapolis di Frigia (Turchia)

2018

The contribution concerns the multidisciplinary research conducted on the North Theatre of Hierapolis in Phrygia (south-western Turkey), built in the 2nd cent. AD and collapsed because of an earthquake in the third quarter of the 4th cent. AD. A systematic analysis and topographical survey of the remains of the Theatre were performed, and plan of the building was integrated into the digital archaeological map of the city. These data were combined with those from the geological study of the site (characterized by landslides) and from the geophysical prospecting (magnetometry and GPR) carried out in the area of the scaena and in the space between the Theatre and the North Agora. The integrati…

An improved Smoothed Particle ElectroMagnetics method in 3D time domain simulations

2012

In this paper, an enhanced variant of the meshless smoothed particle electromagnetics (SPEM) method is performed in order to solve PDEs in time domain describing 3D transient electromagnetic phenomena. The method appears to be very efficient in approximating spatial derivatives in the numerical treatment of Maxwell's curl equations. In many cases, very often, accuracy degradation, due to a lack of particle consistency, severely limits the usefulness of this approach. A numerical corrective strategy, which allows to restore the SPEM consistency, without any modification of the smoothing kernel function and its derivatives, is presented. The method allows to restore the same order of consiste…

The Sylos Postulate reconsidered

2016

This chapter makes a textual comparison between the 1957 2nd Italian edition and the 1962 1st American edition of Oligopoly and Technical Progress, showing that Sylos Labini added to the later edition some fresh sections concerning new firms’ entry and incumbents’ reaction which partially contradict Modigliani’s 1958 presentation of the Sylos Postulate. The theoretical differences between Sylos Labini and Modigliani with regard to the assumption of constant output are traced back to their different modelling strategies on how to tackle the issue of external firms’ conjectures in determining the long-run oligopoly equilibrium price.

Conceptualizing Innovative Business Planning Frameworks to Improving New Venture Strategy Communication and Performance. A Preliminary Analysis of th…

2017

Business planning is a fundamental activity that start-up entrepreneurs are called to carry out in order to attract new investors, business angels, and venture capitalists, to subsidize a new business idea. The key-tool universally used to communicate a new venture strategy to these players, as well as to other stakeholders, is the business plan, i.e. a framework including the business idea description, the product(s), the market sector(s), the core-assets, the budget, the business sustainability and profitability, and so on. As such, a major success factor for drawing up a business plan is the capability to clearly and synthetically communicate the business strategy. Among the others, one …

Analyzing Business Dynamics of Ride-Hailing Services: A DPM Approach Applied to Uber Inc.

2018

Purpose – The purpose of this paper is to explore business dynamics of a rising ride-hailing service industry through case study and foster understanding of hypothetical feedback effects within the broader system. Design/methodology/approach – The research adopts the dynamic performance management framework with simulation-based methodology for developing a dynamic case interpretation of specific type of business complexity. Findings – Scenario analysis shows that changes in the commission percentage for drivers, and cutting prices for customers (car hailers) by competitors have significant impacts on the car hailing industry. Research limitations – The findings of our analysis are limited …

Generalising Theories Explaining the Different Modes of SME Development and the Associated Growth Trajectories

2010

Previous research has identified two forms of “abnormal” growth – styled as business dwarfism and gigantism - which can both lead to missed opportunities for owners/entrepreneurs and local economies, and even to business crisis and collapse. It has also shown that stunted and inflated growth phenomena, rather than being characterised by completely different rules and rationales, are closely related and that certain fundamental structures and processes underpin both those forms of ab-normal company growth behaviour. This paper reports an examination of a further SME phenomenon – what we have chosen to call "micro-giants". These are companies that would be categorised as rela-tively small fir…

A Physiological Approach to Analysing SME Growth Patterns and to Understanding the Distinctions and Similarities between Normal and Abnormal Growth

2010

Building on earlier work on abnormal SME growth trajectories, this paper investigates to what extent the analysis can be extended to the study of an unusual but “normal” growth pattern. The detailed case histories of two firms which might be called micro-giants are presented. These are companies that would be categorised as small firms but are actually competing, and competing successfully, in non-niche markets with much larger firms, or even multinational giants. The resource based view and modelling approaches developed in the earlier non-normal growth situations is then applied to these cases. It is argued that by viewing the management of strategic assets as part of the normal business …

Supporting Multi-Sided Platform firms to maintain rapid growth (and to avoid failure) over time through a Dynamic Business Modelling approach

2020

Over the last few decades, the diffusion of the sharing economy has nurtured continuous changes in business model opportunities with multi-sided platforms (MSPs) in many industries. MSPs are digital exchange platforms aiming at connecting unmatched demand- and supply- side participants through the use of internet technology. In many cases, such start-up initiatives have led to the creation of scale-up or high-growth firms (HGFs). However, in spite of the significant contribution to both economic development and employment, current studies seem to investigate primarily in an isolated perspective HGFs, MSPs and their business model innovation (BMI). The existing literature on HGFs focuses on …
