Le politiche pubbliche e la violenza come “rischio” nella Sicilia occidentale
2014
4. Il saggio prende le mosse dal rifiuto di Franca Viola di sottostare al matrimonio come atto “riparatorio" alla violenza subita, che aveva il potere di derubricare giuridicamente lo stupro perpetrato dal carnefice ma, soprattutto, di riammettere la vittima, in un contesto sociale, pronto, in caso contrario, ad escluderla e stigmatizzarla. Ne descrive i passaggi con cui la Regione Sicilia perviene, circa quaranta anni dopo, all'approvazione della Legge n.3 sulla violenza di genere. Fa il punto sulle associazioni di terzo settore impegnate nel contrasto al fenomeno nella Sicilia occidentale, gli sportelli antiviolenza istituiti e servizi che vengono forniti alle donne vittime di violenza di…
Valoración educativa de un software para el adiestramiento y evaluación de la entonación en instrumentos musicales de cuerda frotada
2021
Aprender a entonar con la viola y el violín es una tarea que requiere tiempo y supervisión. Sin embargo, en los primeros estadios del aprendizaje, los estudiantes iniciados pueden no disponer de las facultades necesarias que les permitan por sí solos supervisar su propia práctica rutinaria en casa. En ese escenario, la tecnología computacional puede tener un papel relevante. Los avances han permitido el desarrollo de herramientas digitales como Cantus Instrumental, que pretende apoyar el proceso de aprendizaje-enseñanza de la entonación con instrumentos musicales ofreciendo varios tipos de retroalimentación, entre otras cualidades. Considerando que la motivación es un constitutivo del apren…
Against all odds : Problem-solving as a skill critical to virtual exchange
2021
Virtual Exchange (VE) brings together groups of learners from different geographical locations and cultural backgrounds to engage them in online intercultural collaboration and interaction. Although VE projects are designed and implemented by educators as part of the students’ educational programmes, they often go beyond the setting of traditional courses offered by higher education institutions. Because of their innovative nature, VEs require the students to leave their comfort zone and think outside the box to develop new creative strategies of communication and collaboration in order to find solutions to problems that crop up in this new learning environment. This presentation showcases …
Anonymiteetin haasteet Bitcoinin käytössä
2019
Tutkielman tavoitteena on selvittää, tarjoaako viimeisen vuosikymmenen aika- na suosioon noussut kryptovaluutta Bitcoin käyttäjilleen anonymiteettiä. Kryptovaluuttojen anonymiteetin tarkasteluun eivät perinteiseen tiedonsiirtoon liitetyt anonymiteetin teoreemat täysin sovellu ja tästä johtuen on muodostettu kryptovaluuttoja koskeva uusi anonymiteetin määritelmä. Tämän uuden määritelmän mukaisesti anonymiteettia tarkastellessa on selvää, että Bitcoin ei oletusarvoisesti tarjoa käyttäjilleen anonymiteettia. Myös vaihtoehtoisia kryptovaluuttoja on Bitcoinin suosion myötä luotu ja useita Bitcoinin sisällä toimivia palveluja on kehitetty anonymiteettiä silmällä pitäen. Tutkielmassa tarkastellaan…
On Creation of a Stablecoin Based on the Morini's Scheme of Inv&Sav Wallets and Antimoney
2021
Decentralized Finance (DeFi) is a popular topic in the blockchain and cryptocurrency industry in the early 2020s. Still, cryptocurrencies have not yet become Decentralized Payment Systems (DPS) because of the high volatility of bitcoin and many of the altcoins. We investigated a proposed method to form a non-collateralized stablecoin called the Morini's Scheme of Inv&Sav wallets. We figured out two equations for the rebasement for the Inv wallet balances and then compared the results. We found the second rebasement method to be fairer to the agents, but we found the issue of negative balances with both methods. We proposed novel solutions to overcome these issues. One of the proposed soluti…
Bitcoin elektronisessa liiketoiminnassa : haasteet ja mahdollisuudet
2016
Digitaalinen raha ja maksujärjestelmä Bitcoin on herättänyt paljon huomiota viime vuosina. Elektronisen liiketoiminnan toimijat ovat kuitenkin olleet hitaita hyväksymään Bitcoinin maksuvälineenä. Syynä tähän on sen kyseenalainen maine ja riskit. Tämän kandidaatintutkielman tarkoituksena oli selvittää Bitcoinin hyödyt ja haitat elektronisessa liiketoiminnassa. Toisena tavoitteena oli selvittää, miten Bitcoinia on ehdotettu kehitettäväksi, jotta siitä tulisi varteenotettavampi maksuväline. Tutkimusmenetelmänä käytettiin kirjallisuuskatsausta. Bitcoinin tärkeimmiksi hyödyiksi havaittiin muun muassa alhaiset transaktiokustannukset etenkin mikromaksumarkkinoilla ja sen pohjalla olevan teknologia…
Behavioral Activation through Virtual Reality for Depression: A Single Case Experimental Design with Multiple Baselines
2022
Behavioral activation (BA) is a structured psychotherapeutic approach for the treatment of major depressive disorder (MDD), which aims at increasing the engagement in activities that might bring enjoyment and meaning to patients’ lives. Although a growing body of evidence supports the effectiveness of BA, enhancing the motivation and activity level of depressed patients is often challenging. In the present study, we explored the effectiveness of a brief BA treatment supported by virtual reality (VR) to facilitate the visualization and anticipation of four pleasurable activities that we tried to re-introduce in the patients’ daily routine. To do so, we conducted a single-case experimental de…
Participation of the young ones in virtual worlds : A look at experiences and motivations
2011
Virtual worlds have become very popular and there have been some attempts to find the motivations and experiences of using them. The aim of this paper is to analyze the motivations and experiences of young ones to utilize virtual worlds. The paper identifies the activities that children perform in virtual worlds, features they use as well as the reasons for abandoning these virtual worlds. The paper presents results of a qualitative field study. The results indicate that features that are liked in the virtual worlds are similar to games. The most liked features for virtual worlds were developing characters and doing things in groups. The activities that were liked the most in virtual worlds…
IVyF: Validez de un Instrumento de Medida de las Fortalezas del Carácter de la Clasificación de Peterson y Seligman (2004)
2015
El IVyF (Strength of Character Inventory, en inglés) es un instrumento de medición de las 24 fortalezas del carácter de la clasificación de Peterson y Seligman (2004). A diferencia de otros cuestionarios homólogos para medir las fortalezas de esa clasificación que están compuestos por decenas de ítems, el IVyF es un instrumento de medición de 24 ítems. Este estudio se enfocó en la validez del IVyF. En primer lugar, el IVyF estuvo asociado a medidas de variables conceptualmente relevantes como satisfacción con la vida, los factores de personalidad del modelo de los Cinco Grandes, y deseabilidad social. En segundo lugar, se hallaron asociaciones con tamaños del efecto mayores a mediano entre …
