Curvelet-based method for orientation estimation of particles
2013
A method based on the curvelet transform is introduced for estimating from two-dimensional images the orientation distribution of small anisotropic particles. Orientation of fibers in paper is considered as a particular application of the method. Theoretical aspects of the suitability of this method are discussed and its efficiency is demonstrated with simulated and real images of fibrous systems. Comparison is made with two traditionally used methods of orientation analysis, and the new curvelet-based method is shown to perform clearly better than these traditional methods.
Curvelet-based method for orientation estimation of particles from optical images

Diversity begets diversity: A global perspective on gender equality in scientific society leadership.
2018
Research shows that gender inequality is still a major issue in academic science, yet academic societies may serve as underappreciated and effective avenues for promoting female leadership. That is, society membership is often self-selective, and board positions are elected (with a high turnover compared to institutions)—these characteristics, among others, may thus create an environment conducive to gender equality. We therefore investigate this potential using an information-theoretic approach to quantify gender equality (male:female ratios) in zoology society boards around the world. We compare alternative models to analyze how society characteristics might predict or correlate with the …
Phantom/liminal fat and feminist theories of the body
2017
This article brings together two concepts, ‘phantom fat’ and ‘liminal fat’, which both aim to grasp how fat in contemporary culture becomes a kind of material immateriality, corporeality in suspension. Comparing the spheres of representation and experience, we examine the challenges and usefulness of these concepts, and feminist fat studies perspectives more broadly, to feminist scholarship on the body. We ask what connects and disconnects fat corporeality and fat studies from ways of theorising other embodied differences, like gender, ‘race’, disability, class and sexuality, especially when thinking through their perceived mutability or removability, and assumptions about their relevance …
Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia
2018
The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…
Le regole per impugnare
2018
Il contributo analizza la disciplina concernente le regole per impugnare. Dopo un inquadramento sistematico delle impugnazioni penali, ci si sofferma sui principi, con particolare riguardo alla tassatività, all'interesse a impugnare alla legittimazione e alla unicità dell'impugnazione. Quindi vengono analizzati gli aspetti formali dell'atto di impugnazione: forma termini luogo e modo di presentazione. Viene prestata particolare attenzione alle novità introdotte dalla c.d. Riforma Orlando in tema di forma dell'impugnazione e specificità dei motivi, con riflessioni critiche. Ancora vengono analizzati i profili attinenti alla inammissibilità e agli effetti delle impugnazioni. Da ultimo ci si s…
Influence of the learning environment on the representational strategies of middle school music students: an intervention-based study
2015
The purpose of this study was to examine the effects of a hypermedia learning environment on middle school students' meta-representational competence (MRC) in the domain of music. Particularly, we aimed at determining whether an educational intervention influenced the accuracy with which middle school students matched sounds (sonic fragments) to symbols (graphic representations). The students were randomly allocated to the experimental condition. An intervention was set up so that the experimental group students (E) were provided with scaffolding aimed at enhancing their use of constructive resources to generate representations and their critical capabilities to judge them. On the other han…
La construcción del territorio a través del ciberespacio: una mirada latinoamericana de la percepción de los jóvenes frente al espacio virtual
2018
El trabajo parte del problema de comprender la sensación de movilidad espacial y la ruptura de un espacio vivido como algo físico e inmediato que genera nuevos desafíos en el aprendizaje, tanto de los jóvenes colombianos, como de otros lugares de América Latina y el mundo. Éllos se abren a una sociedad global sin capacidad de analizar su funcionamiento, exponiéndose al arbitrio de decisiones emanadas de lugares lejanos y que le afectan en su comprensión del mundo vivido. De aquí que se quiera preguntar por ¿Cómo se pueden comprender las nuevas formas de representación del territorio en el ciberespacio desde la visión de los jóvenes de colegios públicos y privados en Villavicencio – Colombia…
Subventionsheuschrecke oder Weltmarktführer? : Nokia-Repräsentation in den Kommentaren der Frankfurter Allgemeinen Zeitung nach der Veröffentlichung…
2010
Tammikuussa 2008 Nokia päätti lopettaa Saksassa toimivan Bochumin tehtaansa toiminnan ja irtisanoa tehtaan 2 300 työntekijää. Tämä päätös johti uutistulvaan saksalaisessa lehdistössä. Ilmiöstä kehittyi poliittisesti arkaluontoinen, kun saksalaiset poliitikot ottivat oman jyrkän kantansa tapahtumalle ja julistivat boikotin Nokiaa vastaan. Tämän työn tarkoituksena on tarkastella, miten Nokiaa kuvattiin Bochumin tehtaan tapahtumien aikana saksalaisessa Frankfurter Allgemeine Zeitung -sanomalehdessä. Analyysissä tutkitaan kriittisen diskurssianalyysin keinoin lehden Kommentar -kirjoitusten nimeämisiä sekä diskursseja, jotka liittyvät Nokiaan ja Bochumin tehtaan sulkemiseen. Nimeämisten ja disku…
Näkyvä lapsuus : lapsuuskuva havainnointipäiväkirjassa ja television mainoskuvissa
2017
This research addresses images of childhood in the context of media and children´s everyday lives. Images of childhood reproduced by young children themselves and by their parents and day-care personnel, and in television advertising were investigated. Representations are studied as social, cultural and historical entities that are formed in the course of everyday life. The question is asked, what kind of childhood is (re)produced in children's everyday lives and in the media context, and how are the representations created using visual and textual materials connected with the cultural imagery of childhood? To collect child observations and descriptions of daily lives as provided by adults …
