Trimmed fuzzy clustering for interval-valued data

Abstract: In this paper, following a partitioning around medoids approach, a fuzzy clustering model for interval-valued data, ie, FCMd-ID, is introduced Successively, for avoiding the disruptive effects of possible outlier interval-valued data in the clustering process, a robust fuzzy clustering model with a trimming rule, called Trimmed Fuzzy $$C$$ C -medoids for interval-valued data (TrFCMd-ID), is proposed In order to show the good performances of the robust clustering model, a simulation study and two applications are provided

Podemos and the Five-star Movement: populist, nationalist or what?

Abstract: The resounding electoral successes of the Italian Movimento Cinque Stelle (Five-star Movement, M5S) and the Spanish Podemos (We can) in recent years, have attracted the attention of many political scientists. The two parties can be considered a new kind of anti-establishment party with values incompatible with those of the radical-right parties. From a normative standpoint, two main allegations have been made against the two parties: both have been considered ‘populist’ and, in some ways, ‘nationalist’. Still, the academic literature so far lacks a detailed analysis of the nature of their alleged populism and nationalism. In this article, I argue that both parties share a populist stance, while the label ‘sovereigntists’ rather than ‘nationalists’ is more appropriate in both cases.

On Information Distortions in Online Ratings

Abstract: Consumer reviews and ratings of products and services have become ubiquitous on the Internet. This paper analyzes, given the sequential nature of reviews and the limited feedback of such past reviews, the information content they communicate to future customers. We consider a model with heterogeneous customers who buy a product of unknown quality and we focus on two different informational settings. In the first setting, customers observe the whole history of past reviews. In the second one they only observe the sample mean of past reviews. We examine under which conditions, in each setting, customers can recover the true quality of the product based on the feedback they observe. In the case of total monitoring, if consumers adopt a fully rational Bayesian updating paradigm, then they asymptotically learn the unknown quality. With access to only the sample mean of past reviews, inference becomes intricate for customers and it is not clear if, when, and how social learning can take place. We first analyze ...

Inequality and marginalisation: social innovation, social entrepreneurship and business model innovation: The common thread of the DRUID Summer Conference 2015

Abstract: Nowadays societies face many societal challenges, among which increasing inequality and marginalisation. This paper uses this key to read the discussion undertaken during the DRUID Conference 2015 ‘Relevance of Innovation’, held at LUISS Business School (Rome, IT). We focus on the speeches, sessions, and debates that were hosted at the conference. We expand them and build on them to advance scholarly discussion on how social innovation, social entrepreneurship and business model innovation can be used to face inequality and marginalisation. The main idea we place at the centre of the discussion is empowerment of marginalised individuals by social innovation initiatives and social entrepreneurial ventures. Business model innovation is seen as instrumental to this, being a crucial tool to foster hybrid organisations and institutions able to merge the social and economic dimensions.
