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…
Deletion and insertion mutants of HBsAg particles
1992
We have found previously that hybrid 22-nm HBsAg particles can be created by insertion of short antigenic sequences into the HBV major envelope protein [1]. We have now performed a detailed deletion mutagenesis of the S gene of HBV encoding HBsAg. Deletion of the 51 C-terminal amino acids including most of the third and all of the fourth hydrophobic domain of the S protein did not affect particle assembly and secretion. However, secretion of 22-nm particles was abolished by minor deletions in the N-terminal region. Insertion and deletion/substitution mutants carrying a poliovirus epitope at the N-terminus and the preSl region at the C-terminus have been characterized.
Halloysite nanotubes as polyolefin fillers
2015
Artykuł stanowi przegląd najnowszej literatury dotyczącej nanokompozytów poliolefinowych napełnianych nanorurkami haloizytowymi (HNT). Omówiono wpływ dodatku HNT na osnowę poliolefinową, ze szczególnym uwzględnieniem morfologii oraz właściwości mechanicznych nanokompozytów poliolefina/HNT. Modyfikowane HNT wykazywały wysoki stopień rozproszenia w osnowie poliolefinowej, dzięki czemu powodowały poprawę właściwości mechanicznych poliolefinowych nanokompozytów napełnianych nanorurkami haloizytowymi. Połączenie korzystnych właściwości poliolefin, ekonomicznych metod ich przetwórstwa oraz unikatowych w³aoeciwooeci HNT pozwoli na szersze rozpowszechnienie nanokompozytów wytworzonych z ich udziałe…
I GESTI MOTORI NELLE SCOLIOSI MINORI
2008
Per scoliosi s'intende una deviazione laterale permanente della colonna vertebrale, che si accompagna ad alterazioni anatomiche delle vertebre e delle altre strutture di sostegno del tronco. La Scoliosis Research Society definisce la scoliosi come una curva (> 10 gradi Cobb) sul piano frontale che si manifesta con un'inclinazione laterale, che comporta l'allontanamento di un certo numero di vertebre dalla linea mediana; questa modificazione dà origine ad una curva laterale, caratterizzata da un apice, essendo la vertebra apice la più scostata dall’ asse mediano, e da vertebre neutre o vertebre limite, alle estremità della curva, dove le articolazioni intervertebrali ritornano verso la linea…
Application of various physiotherapeutic methods in a conservative treatment of neurogenic scoliosis in a comatose patient - a case report
2017
Wstęp: Leczenie zachowawcze skolioz jest trudne i nie zawsze prowadzi do uzyskania poprawy. Korekcja skoliozy u pacjenta przebywającego w śpiączce jest dużym wyzwaniem, ponieważ brak kontaktu z pacjentem oraz związany z tym brak współpracy podczas terapii i niemożność wykonywania ruchów czynnych w dużym stopniu utrudnia leczenie i ogranicza możliwość stosowania w pełni wielu metod terapeutycznych. Ze względu na złożoność problemu praktykowanie jednej metody nie jest skuteczne. Łączne stosowanie kilku metod terapeutycznych może dać pozytywne rezultaty. Cel pracy: Celem pracy jest przedstawienie metod i wyników terapii skoliozy neurogennej u ośmioletniej pacjentki będącej w śpiączce. Opis prz…
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…
Variabilità dell’olio essenziale di finocchio (Foeniculum vulgare Mill.) per effetto di trattamenti agronomici
2009
Il Finocchio da seme (Foeniculum vulgare Mill.), è una specie erbacea annuale o biennale della famiglia delle Apiaceae (ex Ombrellifere), spontanea e largamente diffusa all’interno del bacino del mediterraneo, di cui si utilizzano i frutti (comunemente detti “semi”) come aromatizzanti in numerosi preparati tradizionali e come base per la preparazione di diversi composti di interesse farmaceutico ed alimentare. Il presente lavoro illustra i risultati ottenuti a seguito di un’indagine sulla composizione dell’olio essenziale di finocchio, eseguita utilizzando materiale proveniente da un triennio (2004-2006) di prove agronomiche di controllo delle infestanti svolte in ambiente mediterraneo (Cam…
Scenario modeling for the management of international bond portfolios
1998
We address the problem of portfolio management in the international bond markets. Interest rate risk in the local market, exchange rate volatility across markets, and decisions for hedging currency risk are integral parts of this problem. The paper develops a stochastic programming optimization model for integrating these decisions in a common framework. Monte Carlo simulation procedures, calibrated using historical observations of volatility and correlation data, generate jointly scenarios of interest and exchange rates. The decision maker's risk tolerance is incorporated through a utility function, and additional views on market outlook can also be incorporated in the form of user specifi…
