Trandix: herramienta proactiva para la búsqueda terminológica del traductor y su evaluación
2014
This paper analyses current trends in the terminography field and translators’ needs regarding terminology resources. In this context, the Trandix tool is presented as a novel software application that pursues efficiency in terminological searches conducted by translators. This tool is based on Tarp’s Function Theory of Lexicography (2008a) and Spohr’s proposal concerning electronic multifunctional dictionaries (2009). A further goal of this paper is to serve as an example for future research in terminological resources aiming to meet translators’ requirements and expectations when carrying out terminology searches
An Introduction: "to train and to be trained"
2020
The chapter describes the training model of "Experts in proximity violence and its two main features: 1. the identification of training goals capable of providing specific tools, methods and skills; 2. the creation of a training-course prototype capable of integrating the proposed objectives and the relevant contents in terms of professional spendability.
Ensemble Feature Selection Based on the Contextual Merit
2001
Recent research has proved the benefits of using ensembles of classifiers for classification problems. Ensembles constructed by machine learning methods manipulating the training set are used to create diverse sets of accurate classifiers. Different feature selection techniques based on applying different heuristics for generating base classifiers can be adjusted to specific domain characteristics. In this paper we consider and experiment with the contextual feature merit measure as a feature selection heuristic. We use the diversity of an ensemble as evaluation function in our new algorithm with a refinement cycle. We have evaluated our algorithm on seven data sets from UCI. The experiment…
The Best Hedging Strategy in the Presence of Transaction Costs
2009
Considerable theoretical work has been devoted to the problem of option pricing and hedging with transaction costs. A variety of methods have been suggested and are currently being used for dynamic hedging of options in the presence of transaction costs. However, very little was done on the subject of an empirical comparison of different methods for option hedging with transaction costs. In a few existing studies the different methods are compared by studying their empirical performances in hedging only a plain-vanilla short call option. The reader is tempted to assume that the ranking of the different methods for hedging any kind of option remains the same as that for a vanilla call. The …
Option Pricing and Hedging in the Presence of Transaction Costs and Nonlinear Partial Differential Equations
2008
In the presence of transaction costs the perfect option replication is impossible which invalidates the celebrated Black and Scholes (1973) model. In this chapter we consider some approaches to option pricing and hedging in the presence of transaction costs. The distinguishing feature of all these approaches is that the solution for the option price and hedging strategy is given by a nonlinear partial differential equation (PDE). We start with a review of the Leland (1985) approach which yields a nonlinear parabolic PDE for the option price, one of the first such in finance. Since the Leland's approach to option pricing has been criticized on different grounds, we present a justification of…
European Option Pricing with Transaction Costs and Stochastic Volatility: an Asymptotic Analysis
2015
In this paper the valuation problem of a European call option in presence of both stochastic volatility and transaction costs is considered. In the limit of small transaction costs and fast mean reversion, an asymptotic expression for the option price is obtained. While the dominant term in the expansion it is shown to be the classical Black and Scholes solution, the correction terms appear at $O(\varepsilon^{1/2})$ and $O(\varepsilon)$. The optimal hedging strategy is then explicitly obtained for the Scott's model.
When a virus (Covid-19) attacks human rights: The situation of asylum seekers in the medico-legal setting
2020
The Covid-19 pandemic is a global health emergency that requires immediate, effective action by governments to protect the health and basic human rights of everyone’s life. Refugees and migrants are potentially at increased risk because they typically live in overcrowded conditions often without access to basic sanitation. Since the beginning of the official lockdown for Covid-19, the medico-legal assessment of physical violence related to obtaining status or other forms of human protection has been frozen.
The value of time and transport policies in a parallel road network
2007
Abstract One of the key questions in the evaluation of transport policies and investment decisions is the valuation of the time savings or losses arising from such decisions. This paper uses the stated preference method to determine the value of time in a given traffic context characterised by a road parallel network. The values obtained are higher than usual in Spanish project evaluation which, among other things, points out the need for specific studies of all transport projects whenever possible. Finally, two cases are described which illustrate the relevance of the value of time. The first evaluates time savings related to the pricing policies of a motorway competing with a trunk road. …
First mass measurement at JYFLTRAP
2004
The first mass measurements at JYFLTRAP facility are reviewed. Those are also first ever direct mass measurements of the heaviest Zr-isotopes. Results are compared to atomic mass evaluation data and the recent calculations. The first TOF-resonances from high-precision trap and an implication to high-precision mass measurements are discussed.
