Russian speakers’ media engagement and acculturation in Finland and Latvia

2022

AbstractThis comparative study looks into Russian speakers’ acculturation in Finland and Latvia by contrasting their cultural involvement and cultural preference Carlson and Güler (J Int Migr Integr 19:625–647, 2018. 10.1007/s12134-018-0554-4) with their self-reported news media use. Drawing on survey data collected from both countries (N = 224), the findings show that participants in both countries scored closer to biculturalism than monoculturalism. Majority of the respondents report predominantly engaging with non-Russian news media sources. However, regardless of the societal context, respondents who were more engaged with Russian news media sources also scored higher on cultural prefer…

On the tensor degree of finite groups

2013

We study the number of elements $x$ and $y$ of a finite group $G$ such that $x \otimes y= 1_{_{G \otimes G}}$ in the nonabelian tensor square $G \otimes G$ of $G$. This number, divided by $|G|^2$, is called the tensor degree of $G$ and has connection with the exterior degree, introduced few years ago in [P. Niroomand and R. Rezaei, On the exterior degree of finite groups, Comm. Algebra 39 (2011), 335--343]. The analysis of upper and lower bounds of the tensor degree allows us to find interesting structural restrictions for the whole group.

Le score de propension : un guide méthodologique pour les recherches expérimentales et quasi expérimentales en éducation

2016

La méthode du score de propension devient de plus en plus populaire pour estimer les effets causaux d’un programme d’intervention. Si les applications empiriques de cette méthode sont encore rares dans les recherches en éducation, des exemples de son utilisation se trouvent aisément dans d’autres disciplines. Cependant, sa mise en place soulève plusieurs questions. L’objectif de cet article est de fournir des éléments de réponses guidant le chercheur et l’évaluateur du domaine de l’éducation pour l’estimation et l’utilisation du score de propension. Les différentes étapes de son application sont présentées pas à pas : évaluation du biais de sélection, construction du score de propension et …

Theory and regulation of liquidity risk management in banking

2016

Liquidity risk is now more important than it used to be in the past. The financial crisis has emphasised the importance of liquidity risk to the functioning of banking and financial system. The paper presents a theoretical and regulatory investigation of two types of liquidity risk: funding liquidity risk and market liquidity risk. The paper analyses the different approaches to measure the impact of funding and market liquidity risk in the economics and management of banks. The paper provides also an analysis of the organisational implications of the asset and liability management perspective of liquidity risk. Liquidity risk does not need to be covered by equity but by an adequate volume o…

On the accuracy of three statistical softwares

2005

In this paper we compare the accuracy of three packages that are commonly used for statistical calculations: Excel of Microsoft, version XP Edition 2003, Statistica of Statsoft, version 6, and R, an open-source free software, available on the web, version 1.9.0. To assess the accuracy of each software in different statistical areas, we are going to use benchmarks expressly developed for this aim. The obtained results show a superiority of R in comparison with the other two softwares.

Characterization of a neutron–beta counting system with beta-delayed neutron emitters

2016

A new detection system for the measurement of beta-delayed neutron emission probabilities has been characterized using fission products with well known β-delayed neutron emission properties. The setup consists of BELEN-20, a 4π neutron counter with twenty 3He proportional tubes arranged inside a large polyethylene neutron moderator, a thin Si detector for β counting and a selftriggering digital data acquisition system. The use of delayed-neutron precursors with different neutron emission windows allowed the study of the effect of energy dependency on neutron, β and β-neutron rates. The observed effect is well reproduced by Monte Carlo simulations. The impact of this dependency on the accura…

New insights into the diversity dynamics of Triassic conodonts

2013

International audience; In this paper, we examine the diversity trends and the evolutionary patterns of Triassic conodonts through a newly powered large-scale data-set compiled directly from the primary literature. Paleodiversity dynamics analyses have been undertaken by working at the species level and using a system of time units based on biozone subdivisions for a fine temporal level resolution. The role of heterogeneous duration of taxa in diversity estimates has been evaluated through the probabilistic profiles. Results reveal three different stages in the diversity behaviour of Triassic conodonts from standing metrics delimited by two inflections at the mid-Anisian and mid-Carnian. Su…

Essays on Employment and Unemployment Transitions

2015

The Great Recession has led to important adjustments in the labour market of most developed countries and has dramatically affected the labour market in Spain. According to the Labour Force Survey, the Spanish unemployment rate has increased drastically from 8.5% in 2006 to 25% in 2012 (see the figure). In order to understand the unemployment rate it is important to consider both entry into and exit out of unemployment. This thesis addresses relevant questions for policymakers in line with the objectives of the Europe 2020 strategy. How does the Great Recession affect the patterns and determinants of durations of unemployment and new job matches? How did gender differences in labour market …
