Optimization of net power density in Reverse Electrodialysis

2019

Abstract Reverse Electrodialysis (RED) extracts electrical energy from the salinity difference between two solutions using selective ion exchange membranes. In RED, conditions yielding a large net power density (NPD) are generally desired, due to the still large cost of the membranes. NPD depends on a large number of physical and geometric parameters. Some of these, for example the inlet concentrations of concentrate and diluate, can be regarded as “scenario” variables, imposed by external constraints (e.g., availability) or chosen by different criteria than NPD maximization. Others, namely the thicknesses HCONC, HDIL and the velocities UCONC, UDIL in the concentrate and diluate channels, c…

Block bootstrap methods and the choice of stocks for the long run

2013

Financial advisors commonly recommend that the investment horizon should be rather long in order to benefit from the ‘time diversification’. In this case, in order to choose the optimal portfolio, it is necessary to estimate the risk and reward of several alternative portfolios over a long-run given a sample of observations over a short-run. Two interrelated obstacles in these estimations are lack of sufficient data and the uncertainty in the nature of the return generating process. To overcome these obstacles researchers rely heavily on block bootstrap methods. In this paper we demonstrate that the estimates provided by a block bootstrap method are generally biased and we propose two metho…

The Impact of Bank Concentration on Financial Distress: The Case of the European Banking System

2009

This paper examines the impact of bank concentrationon bank financial distress using a balanced panel of commercial banks in the EU‐25 over a sample period running from 2003 to 2007. Financial distress is proxied by the observations falling below a given threshold of the empirical distribution of a risk‐adjusted indicator of bank performance: the Shareholder Value Ratio. We employ a panel probit regression estimated by GMM in order to obtain consistent and efficient estimates, following the suggestion made by Bertschek and Lechner (1998). After controlling for a number of environment variables, we conclude that our findings suggest a positive effect of bank concentration on financial distre…

The International Legal Framework on Human Trafficking

2020

Approaching the issue of human trafficking, especially when referring to exploitation for sexual purposes, means dissecting concepts and ‘placing’ ourselves within the current binary scholar debate on exploitation and sex work. This chapter presents a chronological excursus on the several international treaties on the issue of human trafficking, with a particular focus on the concept of sexual exploitation. The author delimitates the concept in order to present a precise definition and exclude potential misconceptions that could mislead the reader, especially when vague concepts are included such as vulnerability and consent. Based on an analysis of the current academic debate, as well as t…

The Italian legal clinics movement: Data and prospects

2015

<p>It is not more than 5 years since legal clinics were founded in Italian Universities: a very recent history indeed and similar to that of other Western European countries. I will try to explain this through some data collected by an inquiry that I ran in order to have a more detailed map of this phenomena and to conjecture its future evolution.</p><p>In the following paragraphs I will present the data inquiry and I will try to explain the process of establishing the Italian movement for legal education, its options and challenges.</p><p>It is worth pointing out why I use the term “movement”. What is going on in Italy, and I think elsewhere, is not simply the…

Sustainable Innovation as Competitive Advantage in the Era of Sustainability

2018

The challenges that sustainability raises in front of companies are nowadays bigger than ever, as their actions and performances are increasingly scrutinized and evaluated (by a plethora of different stakeholders) against a variety of sustainability-related expectations and standards. The paper aims to explore the universe of the most sustainable corporations—based on an analysis that corroborates these companies’ engagements towards sustainability (as declared on their websites) with their sustainability-related performances (as reflected in their scores—based on relevant KPIs—according to Corporate Knights’ Global 100 Most Sustainable Corporations)—in order to find relevant insights on th…

The more the ‘Merrier’: A multi-sourced model of addiction

2012

Very few contemporary approaches on addiction specifically aim to address the question of why people who are well-aware of harmful consequences continue to perform addictive behaviours. The aim of this article is to introduce a model of addiction which addresses this question. This model integrates the existing theoretical approaches on addiction in one framework by arguing that the majority of contemporary accounts of addiction are not mutually exclusive in the sense that the occurrence or prominence of one process does not preclude the occurrence of another. Moreover, the suggestion is that the majority of these accounts are in effect supportive of and cooperate with each other in order t…

Toward a More Sustainable Pre-service Teacher Education: A Study in Progress

2015

In this chapter, Toward a more sustainable pre- service teacher education: a study in progress, Claire Vaugelade Berg, Barbro Grevholm, Ase Haraldstad, Bente Velle Hellang, Annbjorg Haoy, Aslaug Kristiansen and Gro-Renee Rambo argue that: “A sustainable teacher education includes developing pre-service teachers’ awareness of the advantages and consequences of adopting a critical stance: a stance where one looks critically and self-critically at everyday-teaching practice, and aim at improving it in order to achieve pupils’ meaningful understanding of the subject matter.” The aim is to supply teachers with relevant skills that make them become well-qualified teachers. The role of developing …

Quantifying Preferential Trading in the e-MID Interbank Market

2013

Interbank markets allow credit institutions to exchange capital for purposes of liquidity management. These markets are among the most liquid markets in the financial system. However, liquidity of interbank markets dropped during the 2007-2008 financial crisis, and such a lack of liquidity influenced the entire economic system. In this paper, we analyze transaction data from the e-MID market which is the only electronic interbank market in the Euro Area and US, over a period of eleven years (1999-2009). We adapt a method developed to detect statistically validated links in a network, in order to reveal preferential trading in a directed network. Preferential trading between banks is detecte…
