Multilayer Network Analysis: The Identification of Key Actors in a Sicilian Mafia Operation

2021

Recently, Social Network Analysis studies have led to an improvement and to a generalization of existing tools to networks with multiple subsystems and layers of connectivity. These kind of networks are usually called multilayer networks. Multilayer networks in which each layer shares at least one node with some other layer in the network are called multiplex networks. Being a multiplex network does not require all nodes to exist on every layer. In this paper, we built a criminal multiplex network which concerns an anti-mafia operation called “Montagna” and it is based on the examination of a pre-trial detention order issued on March 14, 2007 by the judge for preliminary investigations of t…

Brain, Sociobiology, and Evolution in Primates

1981

Socialization in primates can be understood essentially as a function of the information processing ability of the CNS, which can be roughly measured in terms of relative brain size in closely related species groups. Both the cephalization constant (Hemmer 1971, 1974) and the extra neuron number (Jerison 1964, 1973) may be used for relevant quantification, as there is a highly significant correlation of both parameters in primates (7 ape species: r = 0.97, 20 Old World monkey species: r = 0.99; Hemmer 1978). The author has shown in a previous paper (Hemmer 1979) close negative correlations of relative brain size and the social organization as expressed in troop size (r = −0.92) and of relat…

Do Individual Reactions Predict Group Reactions?

1987

Summary.-Group reactions of three-man groups included in 71 junior ice hockey players were measured using a homeostat. Individual reaction times (simple reaction time, choice reaction time) did not predict group performance. In social psychology many studies have compared the effectiveness of an individual and a group (Kelley & Thibaut. 1969). Less research has been done to predict group performance by individuals' performance. In this study group performance was measured by a homeostat developed in the USSR (Medvedev, 1967). Ic consists of three microammeters connected in the same electric network. When the Examiner rotates the electric resistance, the subjects ought to restore the equilib…

Does the platform matter? Social media and COVID-19 conspiracy theory beliefs in 17 countries

2021

While the role of social media in the spread of conspiracy theories has received much attention, a key deficit in previous research is the lack of distinction between different types of platforms. This study places the role of social media affordances in facilitating the spread of conspiracy beliefs at the center of its enquiry. We examine the relationship between platform use and conspiracy theory beliefs related to the COVID-19 pandemic. Relying on the concept of technological affordances, we theorize that variation across key features make some platforms more fertile places for conspiracy beliefs than others. Using data from a crossnational dataset based on a two-wave online survey cond…

Professionals' Views on the Comparatively Low Prevalence of Intimate Partner Violence Against Women in Spain.

2021

The aim of this study was to understand the reasons why Spain has one of the lowest prevalence rates of intimate partner violence against women (IPVAW) in the European Union. Using a qualitative and inductive research approach, a total of five focus groups ( n = 19) and 10 unstructured interviews with key informants were conducted. Three main categories were identified as possible explanations of the relatively low prevalence of IPVAW in Spain: law and policy, social awareness, and cultural patterns. Lessons learned and implications to improve future macrolevel intervention and prevention strategies are discussed.

Measuring Tourist Satisfaction Through a Dual Approach: The 4Q Methodology

2018

Tourist satisfaction is one of the key factors in determining the success of a tourist destination, since it affects behavioural intentions, such as the willingness to revisit and recommend the destination. Therefore, much research has addressed the measuring of tourist satisfaction, either eliciting positive or negative evaluations of a holiday or destination. The spread between expected positive and negative characteristics can trigger a tourist experience. And the gap between expectations and perceptions will produce a feeling of satisfaction or dissatisfaction (Expectancy-Disconfirmation Paradigm, EDP). Under these conditions, this paper adopts a dual approach, considering tourist satis…

Being an athlete and being a young person: Technologies of the self in managing an athletic career in youth ice hockey in Finland

2018

Engaging in youth sports is a major investment, and it requires choosing and balancing between an athlete’s life and other practices and ways of life important to adolescents. In this Foucauldian year-long ethnographic study on Finnish 18–20-year-old elite male ice hockey players I consider an athletic career as a moral question and examine what aspects of their behaviour are affected when these players submit to the external and internal control they encounter when advancing themselves and their careers, and how they problematize the codes that govern their actions. The players expressed six modes of subjection altogether that were important to cultivation of the self: exercising, nutriti…

First data on the taxonomic diversity of the Portulaca oleracea aggregate (Portulacaceae) in Iran

2017

The review of specimens from Iran belonging to the Portulaca oleracea L. aggregate resulted in the recognition of six microspecies: P. cypria Danin, P. granulatostellulata (Poelln.) Ricceri & Arrigoni, P. nitida (Danin & H.G.Baker) Ricceri & Arrigoni, P. rausii Danin, P. socotrana Domina & Raimondo, and P. trituberculata Danin, Domina & Raimondo, all reported for the first time for the flora of Iran. The identification was based on the microscopic study of seeds. It is noted that P. oleracea is not confirmed for Iran. Distribution data and an identification key for Portulaca microspecies in Iran are presented.
