Mafia Methods, Extortion Dynamics and Social Responses

2016

This chapter is devoted to exploring both the empirical results and the policy proposals produced by the GLODERS project. Based on 631 cases of extortions, the Sicily and Calabria extortion database represents a relevant achievement in the field of the research on extortion racket and it is one of the main results of the GLODERS project. Gathering a great amount of information, our empirical analysis revealed the existence of several differences in the extortive conducts carried on within these two regions, which are presented. Moreover, the chapter introduces the legislation related to the crime of extortion. Social and legal responses to the phenomenon are then discussed.

Probabilistic cross-validation estimators for Gaussian process regression

2018

Gaussian Processes (GPs) are state-of-the-art tools for regression. Inference of GP hyperparameters is typically done by maximizing the marginal log-likelihood (ML). If the data truly follows the GP model, using the ML approach is optimal and computationally efficient. Unfortunately very often this is not case and suboptimal results are obtained in terms of prediction error. Alternative procedures such as cross-validation (CV) schemes are often employed instead, but they usually incur in high computational costs. We propose a probabilistic version of CV (PCV) based on two different model pieces in order to reduce the dependence on a specific model choice. PCV presents the benefits from both…

Smart Pedagogy for Technology-Enhanced Learning

2018

The progress of technology has raised challenges to the educational environment, so it is necessary to search for answers to the questions: How can one teach better? How can one scaffold the student in the learning process? What kind of competencies should be developed? What competencies do teachers need? What kind of technology should be used or not be used? This chapter analyses the role of pedagogy for education and outlines the risks for cognitive development that may result from the introduction of technology without an understanding of pedagogical principles. These risks are defined as a centrifugal effect that can be mitigated by integrating technology into the educational process us…

Social interaction in management group meetings: a case study of Finnish hospital.

2016

Purpose – The purpose of this paper is to understand the role of management group meetings (MGMs) in hospital organization by examining the social interaction in these meetings. Design/methodology/approach – This case study approaches social interaction from a structuration point of view. Social network analysis and qualitative content analysis are applied. Findings – The findings show that MGMs are mainly forums for information sharing. Meetings are not held for problem solving or decision making, and operational coordinating is limited. Meeting interaction is very much focused on the chair, and most of the discussion takes place between the chair and one other member, not between members…

Nonlinear femtosecond pulse propagation in an all-solid photonic bandgap fiber

2009

Nonlinear femtosecond pulse propagation in an all-solid photonic bandgap fiber is experimentally and numerically investigated. Guiding light in such fiber occurs via two mechanisms: photonic bandgap in the central silica core or total internal reflection in the germanium doped inclusions. By properly combining spectral filtering, dispersion tailoring and pump coupling into the fiber modes, we experimentally demonstrate efficient supercontinuum generation with controllable spectral bandwidth.

Quine’s Fluted Fragment is Non-elementary

2016

We study the fluted fragment, a decidable fragment of first-order logic with an unbounded number of variables, originally identified by W.V. Quine. We show that the satisfiability problem for this fragment has non-elementary complexity, thus refuting an earlier published claim by W.C. Purdy that it is in NExpTime. More precisely, we consider, for all m greater than 1, the intersectionof the fluted fragment and the m-variable fragment of first-order logic. We show that this subfragment forces (m/2)-tuply exponentially large models, and that its satisfiability problem is (m/2)-NExpTime-hard. We round off by using a corrected version of Purdy’s construction to show that the m-variable fluted f…

Writing as a Learning Tool: An Introduction

2001

This introductory chapter begins with a brief historical account of the writing-to-learn movement, emphasising especially the significance of the cognitive revolution for the development of both teaming research and writing research. The next section considers those theories of the writing process which have had the most profound impact on writing-to-learn, theories of writing as problem solving. Further on, theories and views of learning are discussed as essential determinants of approaches to writing as a learning tool. it is emphasised that current constructivist and social constructivist views imply the use of writing activities requiring transformations of knowledge, social interaction…

Erazm Rykaczewski’s A Complete Dictionary English and Polish… (1849): Uncovering the Compilation Process

2015

This paper looks at Erazm Rykaczewski’s A Complete Dictionary English and Polish... (1849), one of the milestones in the history of English-Polish / Polish-English lexicography. Despite its significance for the bilingual user in Poland and English-speaking countries with large Polish diasporas, where it came to be reprinted over the next century, it has attracted little scholarly attention so far. Based on a comparative analysis of the bilingual dictionary and its assumed sources, the paper sheds some light on the methodology of compilation in which borrowing, adaptation, and translation turn out to have been the lexicographer’s main working practice. The findings are presented in a framewo…

Deriving Enhanced Universal Dependencies from a Hybrid Dependency-Constituency Treebank

2018

The treebanks provided by the Universal Dependencies (UD) initiative are a state-of-the-art resource for cross-lingual and monolingual syntax-based linguistic studies, as well as for multilingual dependency parsing. Creating a UD treebank for a language helps further the UD initiative by providing an important dataset for research and natural language processing in that language. In this paper, we describe how we created a UD treebank for Latvian, and how we obtained both the basic and enhanced UD representations from the data in Latvian Treebank which is annotated according to a hybrid dependency-constituency grammar model. The hybrid model was inspired by Lucien Tesniere’s dependency gram…
