The term structure of volatility predictability
2020
Volatility forecasting is crucial for portfolio management, risk management, and pricing of derivative securities. Still, little is known about the accuracy of volatility forecasts and the horizon of volatility predictability. This paper aims to fill these gaps in the literature. We begin this paper by introducing the notions of the spot and forward predicted volatilities and propose to describe the term structure of volatility predictability by the spot and forward forecast accuracy curves. Then we perform a comprehensive study on the term structure of volatility predictability in the stock and foreign exchange markets. Our results quantify the volatility forecast accuracy across horizons …
Practitioners’ Experiences of Social Media in Career Services
2015
A growing number of career practitioners and career centers are reaching out to individuals and community members in new ways by integrating various social media tools, such as Facebook, Twitter, and LinkedIn, into their professional practices (e.g., Dyson, 2012; Osborn & LoFrisco, 2012). To many, social media are simply online tools to share information and to communicate and socialize with one another. In the broader sense, social media is defined as a process whereby individuals and groups build a common understanding and meaning with contents, communities, and Web 2.0 technology (e.g., Ahlqvist, Back, Heinonen, & Halonen, 2010; Kangas, Toivonen, & Back, 2007).An extensive body of litera…
Competenze docimologiche degli insegnanti di scuola primaria e dell’infanzia
2008
Nel contributo si mette in luce come, attraverso il modo di valutare, sia possibile orientare e dare autonomia al processo di apprendimento, il che significa: rilevare l’interesse e la motivazione dello studente verso particolari argomenti; responsabilizzarlo nel suo processo di apprendimento; orientarlo nelle scelte formative; valorizzare i suoi processi metacognitivi; promuovere la motivazione intrinseca allo studio. Le competenze preludono al diritto all’apprendimento e alla formazione in termini di lunga durata; richiamano processi di pensiero complessi in cui, attraverso idee, concetti e paradigmi, si promuove la personalizzazione delle esperienze conoscitive. Preludono, altresì, ad un…
El Portfolio Europeo de las Lenguas (PEL): herramienta de evaluación de la composición escrita en español como lengua extranjera
2013
Introducción Esta tesis pretende dar respuesta a uno de los desafíos que enfrentan los profesores de lenguas segundas (L2): mejorar la calidad de la evaluación de la expresión escrita. Partimos de la base del Marco Común Europeo de Referencia para las Lenguas (MCER), publicado por el Consejo de Europa con la intención de orientar la enseñanza y evaluación de lenguas, y del Portfolio Europeo de las Lenguas (PEL), cuyo propósito es aplicar en el aula los principios del MCER. Nos preguntamos si el PEL, que ha sido ampliamente experimentado en Educación Primaria y Secundaria, puede ser también útil como herramienta de evaluación de la composición escrita en niveles universitarios con estudiante…

Nello specifico si descriverà brevemente in che modo sia stato possibile realizzare e utilizzare uno strumento ad alto impatto, che ha il potenziale per generare esperienze di apprendim…

Do Investors Care About Noise Trader Risk?
2011
International audience; The link between investor sentiment and asset valuation is at the center of a long-running debate in behavioral finance. Using a new composite sentiment indicator, we show that the conventional risk does not explain the abnormal returns of portfolios most sensitive to the sentiment factor. Our result supports the existence of a sentiment risk valued by financial markets. We also find that the firms more impacted by the sentiment risk correspond to difficult-to-arbitrage and hard-to-value stocks, e.g. small stocks, growth stocks, young stocks, unprofitable stocks, lower dividend-paying stocks, intangible stocks and high volatility stocks.

STUDY REGARDING THE MARKOWITZ MODEL OF PORTFOLIO SELECTION
2015
The Markowitz model was introduced through the work of Harry Markowitz (1952) and analyzes the risk and the rentability of a diversified portfolio of securities. In our research, we want to use the Markowitz model in order to identify the structure of the optimal portfolio of risky assets, in other words the efficient portofolio. The study, conducted on three romanian companies from the construction sector, listed on the Bucharest Stock Exchange, leads to the conclusion that the portfolio is illegitimate, so it is necessary to sell the securities of the companies in the absence, procedure known as short sell.
