A New Perspective on the Relationship between Trading Variables and Volatility in Futures Markets

2017

In this paper, we study the relationship between trading-related variables and volatility in futures markets, from a new unifying perspective, which is based on the separation of open and closed positions. Volatility in stock index futures markets (Standard & Poor’s 500, DAX 30 and Nikkei 225) is related to the flow of contracts entered into the markets and the flow of contracts that are closed out. In general, the daily changes in the number of open and closed positions are both positively correlated with volatility. Additionally, there is a stronger positive relationship between the number of open (respectively, closed) positions and contemporaneous volatility on those days when t…

Double copies of blaKPC-3::Tn4401a on an IncX3 plasmid in Klebsiella pneumoniae successful clone ST512 from Italy

2015

ABSTRACT A carbapenem-resistant sequence type 512 (ST512) Klebsiella pneumoniae carbapenemase 3 (KPC-3)-producing K. pneumoniae strain showing a novel variant plasmid content was isolated in Palermo, Italy, in 2014. ST512 is a worldwide successful clone associated with the spread of bla KPC genes located on the IncFIIk pKpQIL plasmid. In our ST512 strain, the bla KPC-3 gene was unusually located on an IncX3 plasmid, whose complete sequence was determined. Two copies of bla KPC-3 ::Tn 4401a caused by intramolecular transposition events were detected in the plasmid.

Capturing situational interest in the past : the salience of children’s experiences in open-air museums 

2019

Open-air museums are immersive learning environments disseminating ideas about the lifestyle and material culture of pre-modern times. Considering their significance and prevalence in Northern and Eastern Europe, little is known about how contemporary children perceive these cultural heritage spaces. This study scrutinizes how primary school pupils from Sweden and Belarus encountered visits to Skansen (Sweden) and the Belarusian State Museum of Folk Architecture and Rural Lifestyle (Belarus) and expressed experiences about their visits in drawings and in follow-up interpretations. To record the patterns in children’s experiences, a mixed method was employed, including participant observatio…

International Assessment Surveys of Educational Achievement in Developing Countries : Why Education Economists Should Care

2015

International audience; This paper reviews the most known international assessment studies that are conducted in the context of poor countries and highlights the lack of empirical evidence on the degree to which the contents of the tests really match countries' curricula. To illustrate, the paper evaluates the sensitivity of an international testing instrument by comparing the responses of students in two consecutive grades on the same battery of tests. Using propensity score matching to control for student and teacher characteristics, the results show that the tests are not grade sensitive, which raises the question of the validity of many empirical works that are based on similar instrume…

Tensions and challenges concerning ethics on video research with young children : experiences from an international collaboration among seven countri…

2018

This article and the four videos linked to this article are a result of the earliest experiences in establishing an international research collaboration among seven countries in the Project Social and emotional experiences in transition through the early years. We draw attention to the complex issues surrounding the many processes, beliefs and attitudes about infants in research that permeated our processes of gaining ethical approval for the international study and which posed many challenges for our project. Through a process of reflective analysis, we have identified a range of ethical tensions and issues which the different countries involved in this international study faced in gaining…

Platelet cut-off for anticoagulant therapy in thrombocytopenic patients with blood cancer and venous thromboembolism: an expert consensus

2019

Background. Management of venous thromboembolism (VTE) in patients with haematologic malignancies and thrombocytopenia is clinically challenging due to the related risks. No prospective studies or clinical trials have been carried out and, therefore, no solid evidence on this compelling issue is available. Methods. Given this, an expert panel endorsed by the Gruppo Italiano Malattie Ematologiche dell'Adulto Working Party on Thrombosis and Haemostasis was set up to produce a formal consensus, according to the RAND method, in order to issue clinical recommendations about the platelet (PLT) cut-off for safe administration of low molecular weight heparin (LMWH) in thrombocytopenic (PLT <100×…

Reliable Outer Bounds for the Dual Simplex Algorithm with Interval Right-hand Side

2013

International audience; In this article, we describe the reliable computation of outer bounds for linear programming problems occuring in linear relaxations derived from the Bernstein polynomials. The computation uses interval arithmetic for the Gauss-Jordan pivot steps on a simplex tableau. The resulting errors are stored as interval right hand sides. Additionally, we show how to generate a start basis for the linear programs of this type. We give details of the implementation using OpenMP and comment on numerical experiments.

Internationalization, networks and industry related factors : the case of Finnish digital game industry

2016

Tässä työssä tutkittiin pienten ja keskisuurten (PK) yritysten kansainvälistymistä, myyntiä ja verkostoja pienen ja avoimen talouden kontekstissa. Tutkimusaukko perustui tarpeeseen tutkia miten PK -yritykset ja International New Venture (INV) -yritykset kansainvälistyvät, miten verkostoja käytetään tässä prosessissa ja miten toimialan erityispiirteet vaikuttavat käyttäytymiseen. Teoreettinen viitekehys muodostui stage -malleista (Uppsala -malli), INV -teoriasta ja kansainvälistymisen verkostomallista yhdistettynä taloudellisesti kasvavan ja menestyvän digitaalisen pelialan kontekstiin. Tämän kvalitatiivisen tapaustutkimuksen empiirinen data koostui kymmenestä (10) suomalaisten peliyritysten…
