Traffic Management of Video on Demand: An Analysis of Investments for Improving the End User's Quality of Experience:
The current escalation in user demand for web contents, particularly Video on Demand (VoD), is causing a continu‐ ing increase in both the types of web traffic and the volumes of data transmitted. The greater demand arises from the new means of communication employed by individuals and companies, as well as the development of readily usable applications distributed by 'app stores'. In this paper, we suggest that the stakeholders of a VoD frame‐ work, the Content Providers (CPs) and the Internet Service Providers (telcos/ISPs), should guarantee a solid Quality of Experience (QoE) to the end user through two potential investments: either in ultra-broadband (UBB) or in the technologies for the acceleration of web content, known as the Content Delivery Network (CDN) and Transparent Internet Caching (TIC). The aim of the paper is to analyse these investments in terms of providers' profits. The base hypothesis is that the investments are subsidized by the CPs, which, in recent years, have indeed been directing a large part of their revenues towards investments in network infrastructure
Competiveness and Innovation in High-tech Companies: an Application to the Italian Biotech and Aerospace Industries
Innovation activities are a critical factor in national and regional development. The innovative behaviour of companies is one of the main sources of competitiveness, business survival, economic growth and employment in a territory. It is therefore important to identify and understand the factors that determine innovation behaviour among enterprises. In line with this, the aim of this study is to analyse the relations between innovation‐related variables and the impact that they have on company performance. The research model proposed is applied to two high‐tech sectors of the Italian region of Lazio to verify its validity. The examination concerns the aerospace and biotech sectors, which are characterized by strong innovative activity
A New Approach for Assessing Dealership Performance: An Application for the Automotive Industry
The competitive nature of the contemporary business scenario requires productivity‐driven organizations to be aware of the efficiency level of their dealers. The recent economic and financial crisis has highlighted the need for effective evaluation methods going beyond the limits of traditional performance assessment methodologies in the retail industry. The automotive industry is no exception to this logic. In this sector, traditional methods are often based only on market share performances, ignoring the key role of input‐output ratios on the overall productivity of the parent company. Following this lead, in this paper we propose a method to evaluate the performance of dealerships taking into account both their market share performances and their efficiency. In order to assess dealership efficiency we use the DEA technique, and apply the proposed methodology to a multinational automotive company considering its Italian dealer network
Environmental performance versus economic-financial performance: evidence from Italian firms
The aim of the study is to evaluate the economic-financial performance of a sample of 236 Italian companies in relation to their environmental performance, measured in terms of CO2 emissions normalized by company turnover. In addition to the company’s economic management, the analysis also considers the equity structure and company liquidity, over a period of 6 years (2008-2013). The analysis involves the creation of four maps of positioning, serving to represent the companies of the sample in relation to their different attitudes: (i) Green efficiency, (ii) operational efficiency, (iii) company profitability, (iv) financial viability, (v) company liquidity. The examination of positioning maps also serves in identifying extreme cases, meaning the totally inefficient and the “virtuous” companies, and for conducting sectoral analyses to evaluate potential relations between company performances and the characteristics of their industrial sector
The Effects of Online Brand Communities on Brand Equity in the Luxury Fashion Industry
Quoting the fashion genius Coco Chanel: “Fashion is not something that exists in dresses only. Fashion is in the sky, in the street, fashion has to do with ideas, the way we live, what is happening.” This is even more true today than it was back then. Indeed, Web 2.0 technologies have made luxury fashion more accessible to everyone. Nowadays, consumers can instantly access a wide variety of fashion goods on the Internet and share brand experiences with other consumers. In this scenario, Online Brand Communities (OBCs) allow fashion customers to communicate with each other without any restrictions of time and place. For this reason, OBCs are viewed by fashion marketers as powerful instruments to influence customers’ purchasing behaviour. The aim of the current study is to analyse the effects of OBC dynamics on brand equity. The proposed research model is applied to eight spontaneous OBCs of the luxury fashion industry
Understanding How the Strategic Similarities between Energy Companies Influence the Post-mergers and Acquisitions Performances
The energy sector has experienced rapid evolution in recent years, following the liberalization of the electricity and natural gas markets, driven by the European Union. These developments have led to a certain level of dynamism in Italy, particularly as concerns mergers and acquisitions (M&As) within the sector. This article examines the influence of strategic similarities between the target and bidder companies on their post-M&A performances. The model used involves a hierarchical regression relating the indexes of similarity between the merging companies, regarding their economic-financial management. The results reveal the influence of the strategic similarities and differences on the post-M&A performances of the companies, showing how the positive or negative effect depends on certain characteristics, such as their structure of share capital, business segments and size. The study evidences the strategic variables that should be considered in choosing the optimal target companies.
Keywords: Liberalization of energy sectors, M&As, Company performance evaluation, Strategic similarity index, Target company's characteristics.

Regulatory Response to Self-production of Energy: A Risk for the Development of Renewable Sources and Combined Heat and Power
The high price for electrical energy increasingly leads companies to engage in self-production, so as to reduce costs, increase their own energy efficiency, and achieve market competitiveness. In general such self-production solutions have positive environmental impacts, since they involve exploitation of renewable sources and high-yield cogeneration plants, as well as avoiding inefficiencies due to network losses. However, the resulting reduction in the network exchange of electrical energy does not lead to proportional reductions in the network costs, and finding adequate coverage for these remains a necessity. Given this context, the role of the regulator becomes fundamental. The regulator must implement strategies for purposes of meeting national needs in regards to costs, but without excessively penalizing the companies and their international competitiveness, and without holding back development of environmentally favourable and sustainable solutions. The current article analyzes the possible regulatory interventions, their technical and organizational difficulties, and the impacts of these strategies in the national context.

Severe asthma features in children: a case-control online survey
BACKGROUND:
Very few studies have explored the distinguishing features of severe asthma in childhood in Europe, and only one study was conducted in Southern Europe. The aim of this study was to provide a detailed characterization of children with severe asthma treated in specialized pediatric asthma centers across Italy.
METHODS:
We conducted a web-based data collection of family, environmental, clinical and laboratory characteristics of 41 patients aged 6-17 years with severe asthma, defined according to the recent guidelines of the European Respiratory Society and the American Thoracic Society, and 78 age-matched peers with non-severe persistent asthma. The patients have been enrolled from 16 hospital-based pediatric pulmonology and allergy centers in Northern, Central, and Southern Italy. Logistic regression analysis assessed the relationship between patients' characteristics and severe asthma or non-severe persistent asthma.
RESULTS:
Features independently and significantly associated with severe asthma included lifetime sensitization to food allergens [Odds ratio (OR), 4.73; 95 % Confidence Interval (CI), 1.21-18.53; p = 0.03], lifetime hospitalization for asthma (OR, 3.71; 95 % CI, 1.11-12.33; p = 0.03), emergency-department visits for asthma during the past year (OR = 11.98; 95 % CI, 2.70-53.11; p = 0.001), and symptoms triggered by physical activity (OR = 12.78; 95 % CI, 2.66-61.40; p = 0.001). Quality-of-life score was worse in patients with severe asthma than in subjects with non-severe persistent asthma (5.9 versus 6.6, p = 0.005). Self-perception of wellbeing was compromised in more than 40 % of patients in both groups. Children with severe asthma had lower spirometric z scores than non-severe asthmatic peers (all p < 0.001), although 56 % of them had a normal forced expiratory volume in 1 s. No differences were found between the two groups for parental education, home environment, patients' comorbidities, adherence to therapy, exhaled nitric oxide values, and serum eosinophils and IgE .
CONCLUSIONS:
As expected, children with severe asthma had more severe clinical course and worse lung function than peers with non-severe persistent asthma. Unlike previous reports, we found greater sensitization to food allergens and similar environmental and personal characteristics in patients with severe asthma compared to those with non-severe persistent asthma. Psychological aspects are compromised in a large number of cases and deserve further investigation
