Using Agent-Based Modelling in Studying Labour–Education Market System

2015

We’re now ready for a discussion on how exactly one could build an agent-based model of labour–education market system (LEMS). This discussion will necessarily be quite abstract, because particular mechanisms built into the model (agents, their behaviour, interactions, other structures) depend heavily on the purpose of the model. I’ll focus on general approaches and mechanisms that you may find useful when building agent-based models of LEMS.

Reti mafiose. Cosa nostra e camorra: organizzazioni criminali a confronto

2011

Nella vastissima produzione editoriale sul fenomeno mafioso i gruppi criminali sono stati spesso rappresentati come organizzazioni verticistiche, fortemente centralizzate e gerarchizzate. Si è fatto spesso ricorso alla metafora della piramide, della burocrazia o dell'azienda, evidenziando, in tal modo, la presenza di una netta articolazione interna e di una precisa suddivisione dei ruoli e delle funzioni tra i singoli associati. Pur riconoscendo l'efficacia e la persistente attualità di una simile rappresentazione, questo volume guarda alle organizzazioni criminali da un punto di vista differente, adoperando una prospettiva di analisi di tipo relazionale. Le singole cosche possono essere, i…

Marketing communication metrics for social media

2011

The objective of this paper is to develop a conceptual framework for measuring the effectiveness of social media marketing communications. Specifically, we study whether the existing marketing communications performance metrics are still valid in the changing digitalised communications landscape, or whether it is time to rethink them, or even to devise entirely new metrics. Recent advances in information technology and marketing bring a need to re-examine measurement models. We combine two important research topics and set directions for potential future research. Metrics to measure marketing communications performance have developed towards a customer orientation. There is no broadly accep…

Uncertain outcome presentations bias decisions: experimental evidence from Finland and Italy

2016

Even in their everyday lives people are expected to make difficult decisions objectively and rationally, no matter how complex or uncertain the situation. In this research, we study how the format of presentation and the amount of presented information concerning risky events influence the decision-making process, and the propensity to take risk in decision makers. The results of an exploratory survey conducted in Finland and in Italy suggest that decision-making behavior changes according to the way the information is presented. We provide experimental evidence that different representations of expected outcomes create distinct cognitive biases and as a result affect the decisions made. Th…

Découverte des relations dans les réseaux sociaux

2011

In recent years, social network sites exploded in popularity and become an important part of the online activities on the web. This success is related to the various services/functionalities provided by each site (ranging from media sharing, tagging, blogging, and mainly to online social networking) pushing users to subscribe to several sites and consequently to create several social networks for different purposes and contexts (professional, private, etc.). Nevertheless, current tools and sites provide limited functionalities to organize and identify relationship types within and across social networks which is required in several scenarios such as enforcing users’ privacy, and enhancing t…

Nethnography and Social Network Analysis for Studying Online Social Space

2022

Author's accepted manuscript This chapter contributes to the current methodological debate on digital, internet-based studies in social research. Based upon an introductive analysis of the research's perspectives, trajectories, and stages that have brought the online social spaces into social research, the chapter focuses on the advantages of combining quanti-quali approaches for approaching online complexity. In particular, the authors offer a deep discussion concerning the value, the methodological, and ethical challenges of netnography and social network analysis (SNA) methods for inquiring online social research by proposing a possible emerging methodological framework guiding further e…

Scientific networks and research groups development: educational Psychology case in Spain during the five-year periods 2004-2008 and 2009-2013

2017

El objetivo de este estudio ha sido identificar y conocer los cambios experimentados en los grupos de la comunidad científica de auto- res que trabajan en instituciones españolas y que publican artículos en las revistas científicas incluidas en la categoría "Psychology Educational" en la Web of Science durante el período 2004 hasta el 2013 y su pertenencia y perma- nencia en los diferentes grupos de investigación. Se realizó un estudio com- parativo de los grupos y su composición a lo largo de los quinquenios 2004- 2008 y 2009-2013.

Electronic surveillance in the couple: The role of self-efficacy and commitment

2021

Abstract Researchers have shown a significant effect of using social networking sites (SNSs) on romantic relationships. Surveillance is one of the motives for social network use. Social networking surveillance is related to controlling a romantic partner's online behaviours. The purpose of the study was to search for antecedents of electronic surveillance (Study 1) and to examine their role in behaviours related to electronic surveillance among romantic couples (Study 2). Following the uses and gratification theory and technology acceptance model of using SNSs, antecedents of electronic surveillance in adult Facebook users were examined. In Study 1, the relationship between electronic surve…

Marginal contribution, reciprocity and equity in segregated groups: Bounded rationality and selforganization in social networks

2007

We study the formation of social networks that are based on local interaction and simple rule following. Agents evaluate the profitability of link formation on the basis of the Myerson-Shapley principle that payoffs come from the marginal contribution they make to coalitions. The NP-hard problem associated with the Myerson-Shapley value is replaced by a boundedly rational 'spatially' myopic process. Agents consider payoffs from direct links with their neighbours (level 1), which can include indirect payoffs from neighbours' neighbours (level 2) and up to M-levels that are far from global. Agents dynamically break away from the neighbour to whom they make the least marginal contribution. Com…
