Extreme voting under proportional representation: the multidimensional case

We study the strategic behavior of voters in a spatial model of proportional representation, in which the policy space is multidimensional. Our main finding is that in large electorate, under some assumptions on voters’ preferences, voters essentially vote, in any equilibrium, only for the extreme parties.     

“Isn't it ironic…!?!” Mobility researchers go sedentary: A group auto-ethnography on collective coping and care in pandemic times

We moved places and places moved us, until force majeure detained us on the spot. Signed-up to be hyper-mobile Ph.D.-candidates, we became hyper-reflective pandemic intimates. We moved together into a space that felt safe, OUR safe space. Suspended. Did the pandemic open this door, or had this space always existed, even back in the old days? Probably the latter, although we were not sensitive enough to perceive it, too busy to push the door, too lonesome to CARE. Not attentive to its possibilities, not imaginative of its POWER, too confident to be capable of succeeding alone. Even if we might have secretly wished for this space to exist. The present piece of work, and JOY, might be described by others as a “side-step,” a “hobby project,” a “shadow activity.” For us, it is a recollection of shocks and wonders, a sentience of precious, ephemeral instances that last. We are a group of eight early career researchers who study global mobility and labor migration from a variety of disciplinary perspectives. With prior international mobility experience, we left our previous countries of residence in 2018 to join an EU-funded research project, whilst being located in different European cities. One could classify us, for example, as highly qualified, privileged migrants. The present paper is the outcome of a collaborative, auto-ethnographic study, conducted in 2020, in the midst of the Covid-19 pandemic, when we suddenly were forced not to travel anymore. We got together online every week to “refaire le monde,” and we conducted virtual, dialogical self-interrogations and group reflections. Based on an emic approach, in line with Chang et al. (2013), we applied an iterative process of data collection and analysis. Our weekly conversations naturally emerged as a safe space for exchange and understanding, as we were facing similar situations, despite staying at different places. Suddenly, as the privilege of “always being on the move,” “always socializing and networking” disappeared due to closed borders and pandemic threats, we experienced anxieties and isolation and had to re-evaluate our perceptions on life, work, and international mobility. The very purpose and meaning of our broader research endeavors and employment perspectives suddenly faded away. We realized more than ever before, what it means to us to be allowed to move, to travel freely across continents.     

The Role and Implications of Values-based Leadership

This paper aims at analysing conceptually spiritual leadership in the organizational field. First, we identify if a relation between spirituality and leadership can exist and then if and how this influences employer/employees reciprocal behaviour. In the early years, the focus has changed, trying to deepen the differences between religion and spirituality and emphasizing the last one as a source of success for leaders. We focused on the understanding of the effects that spirituality has on the system of values and the role of values and emotions in determining a successful leader. Finally, we emphasize the role of values-based leadership capabilities within strategic management, aiming at highlighting the importance of a shared system of values in leading employees.     

Living in the Now: Decision-Making and Delay Discounting in Adolescent Gamblers

Several studies examining the relationship of affective decision-making and delay discounting in disordered gambling demonstrated that adult pathological gamblers differ from healthy controls on both reward-related decision tasks. To date no study analyzed the relative contribution of these variables in adolescent gambling. This study was designed to compare affective decision-making and delay discounting in gamblers and nongamblers Italian adolescents, controlling for alcohol consumption. A total of 138 adolescents took part in the research. Two equal-number groups, defined according to the scoring rules for the South Oaks Gambling Screen-Revised for Adolescents, were administered the Iowa Gambling Task (IGT), the Monetary Choice Questionnaire (MCQ), and the Alcohol Use Disorders Identification Test (AUDIT). Zero-order correlations among all variables revealed a moderate negative association between IGT and MCQ scores only in nongamblers group. Results of mixed-model ANOVAs indicated that, compared with nongamblers, adolescent gamblers performed worse on the IGT, showed steeper delay discounting, and scored significantly higher on the AUDIT. Results of logistic regression analysis indicated that IGT, MCQ, and AUDIT scores are all significant predictors of gambling status. This novel finding provides the first evidence of an association among problematic gambling, maladaptive decision-making, and steep delay discounting among adolescents, as already observed in adults.     

A comparative study on Italian new communities abroad: the cases of Tunisia and South Africa1

This paper presents two case studies about Italian new communities abroad: one Tunisian and one South African. These case studies were conducted – in a larger international research project on 14 countries – with different types of interview: focus interviews, in-depth interviews, focus groups, etc. The mixed interview modes brought to light how – with a different research strategy (methodological triangulation): quantitative and qualitative data – our complex social experience can be inquired into, in particular migration processes. The authors decided to utilise semi-standardised and non-standardised techniques. This paper discusses how the mixed research logic – utilised in both of these cases – is very productive in terms of knowledge. It seems that focus group interviewing techniques (and others) have been used progressively more and more over the past years as both a self-contained method for conducting qualitative research and in combination with other research methods. In the authors’ opinion, mixed-methods research (or multiple research strategies) represents a smaller corpus of literature that is getting increased attention. The essays in our paper are grouped along four themes: (a) economic development and globalisation; (b) perceptions and discourses; (c) the new migration phenomenon; and (d) fragmentation of identity. The authors believe that rebuilding a morceau de vie of Italian emigration helps to better analyse the role of the communities of immigrants in the construction of national processes. As a result of this, their survey introduces reflections on theoretical—methodological logic and concurs with placing such aspects in a global and social structural dimension. However, the universal and social structural dimension can be extended to the specific case. Its contribution in the first part investigates a variety of linkages of migration with broader processes of social–economic development and social globalisation. That global patterns of migration and the processes of globalisation are linked in various ways has long been recognised. The second part of the paper stresses the meaning of perceptions and discourses linked with the migration phenomenon and underlines the importance of an accurate methodological approach in order to provide new sociological points of view and appropriate research strategies.     

On large enterprises: new findings from a European comparison

The recent evolution of Italian capitalism shows the increasing relevance of large enterprises at three levels: the economic and institutional environment, the ownership structure, and the financing policy. A comparison of the financial structure of Italian large enterprises with those of other European countries (France, Germany, and Spain), using Bank for the Accounts of Companies Harmonised data, shows their financial fragility, where the prevalence of debt over equity justifies the still strong and close relationship between ownership control and management in their strategies and the prevalence of obsolete bank–firm relationships based on short-term external finance and multiple business lendings. These factors slow down firms’ expansion and consequently the need for companies to grow so as to face the new global market. Finance is confirmed as a determinant of growth both in size and in organisation. We conclude that a pivotal role for the growth of Italian firms lies in a “revised” relationship between size, governance, and the firms’ financial structure.     

Density-based Silhouette diagnostics for clustering methods

Silhouette information evaluates the quality of the partition detected by a clustering technique. Since it is based on a measure of distance between the clustered observations, its standard formulation is not adequate when a density-based clustering technique is used. In this work we propose a suitable modification of the Silhouette information aimed at evaluating the quality of clusters in a density-based framework. It is based on the estimation of the data posterior probabilities of belonging to the clusters and may be used to measure our confidence about data allocation to the clusters as well as to choose the best partition among different ones.
