Public opinion on useful languages in Europe

This article analyses the results of five Eurobarometer surveys (of 1995, 1997, 1998, 2000 and 2005) designed to measure which languages Europeans consider most useful to know. Most Europeans are of the opinion that English is the most useful, followed by French and German. During the last decade the popularity of French and German as useful languages has been decreasing significantly, while English has remained universally favoured as the most useful language. French and German have lost their popularity especially among those who do not speak them as a foreign language. On the other hand, Spanish, Russian and other languages (often these include languages of neighbouring countries, minority languages or a second official language of the country in question) have kept and even increased their former level of popularity. Opinions about useful languages vary according to a respondent’s knowledge of languages, education and profession. This article analyses these differences and discusses their impact on the study of foreign languages and the future of the practice of foreign languages in Europe.

Measurement of the ttbar production cross section with an in situ calibration of b-jet identification efficiency

A measurement of the top-quark pair-production cross section in ppbar collisions at sqrt{s}=1.96 TeV using data corresponding to an integrated luminosity of 1.12/fb collected with the Collider Detector at Fermilab is presented. Decays of top-quark pairs into the final states e nu + jets and mu nu + jets are selected, and the cross section and the b-jet identification efficiency are determined using a new measurement technique which requires that the measured cross sections with exactly one and multiple identified b-quarks from the top-quark decays agree. Assuming a top-quark mass of 175 GeV/c^2, a cross section of 8.5+/-0.6(stat.)+/-0.7(syst.) pb is measured.

Maahanmuuttajien yhteiskunnallisen osallistumisen tukeminen julkishallinnossa ja puolueissa

I denna utredning har det kartlagts de åtgärder som de finska regionala och lokala förvaltningsmyndigheterna och riksdagspartierna har vidtagit för att stöda invandrares samhälleliga och politiska deltagande. Dessutom har man betraktat undervisningen om och behandlingen av teman som gäller samhälleligt och politiskt deltagande på integrationskurser. Materialet som utnyttjas vid kartläggningen har samlats in genom förfrågningar, som har sänts till ELYcentralerna, de största kommunerna, riksdagspartierna och de läroanstalter som ordnar integrationskurser. Utredningen hör till projektet Likabehandling på första plats 3 (YES 3, på finska Yhdenvertaisuus etusijalle). YESprojektet är en nationell kampanj mot diskriminering vars mål är att öka medvetenheten om och beredskapen för likabehandling och ickediskriminering och att främja godkännandet av pluralism i samhället. Projektet finansieras av EUkommissionens PROGRESSprogram (20072013) samt av de organisationer som deltagit i projektet. Justitieministeriet har deltagit i YES 3projektet med ett eget delprojekt, vars mål är att öka invandrarnas samhälleliga delaktighet, deras kanaler för deltagande och deras kunskaper om de grundläggande rättigheterna.

Central Diffraction at ALICE

The ALICE experiment is shown to be well suited for studies of exclusive final states from central diffractive reactions. The gluon-rich environment ofthe central system allows detailed QCD studies and searches for exotic mesonstates, such as glueballs, hybrids and new charmonium-like states. It wouldalso provide a good testing ground for detailed studies of heavy quarkonia. Dueto its central barrel performance, ALICE can accurately measure the low-masscentral systems with good purity. The efficiency of the Forward MultiplicityDetector (FMD) and the Forward Shower Counter (FSC) system for detectingrapidity gaps is shown to be adequate for the proposed studies. With thisdetector arrangement, valuable new data can be obtained by tagging centraldiffractive processes.

Association between molecular variation in the phosphoglucose isomerase (Pgi) locus and migration propensity in the Glanville fritillary butterfly

Habitat fragmentation produces patches of suitable habitat surrounded by unfavourable matrix habitat. A species may persist in such a fragmented landscape in an equilibrium between the extinctions and recolonizations of local populations, thus forming a metapopulation. Migration between local populations is necessary for the long-term persistence of a metapopulation. The Glanville fritillary butterfly (Melitaea cinxia) forms a metapopulation in the Åland islands in Finland. There is migration between the populations, the extent of which is affected by several environmental factors and variation in the phenotype of individual butterflies. Different allelic forms of the glycolytic enzyme phosphoglucose isomerase (Pgi) has been identified as a possible genetic factor influencing flight performance and migration rate in this species. The frequency of a certain Pgi allele, Pgi-f, follows the same pattern in relation to population age and connectivity as migration propensity. Furthermore, variation in flight metabolic performance, which is likely to affect migration propensity, has been linked to genetic variation in Pgi or a closely linked locus. The aim of this study was to investigate the association between Pgi genotype and the migration propensity in the Glanville fritillary both at the individual and population levels using a statistical modelling approach. A mark-release-recapture (MRR) study was conducted in a habitat patch network of M. cinxia in Åland to collect data on the movements of individual butterflies. Larval samples from the study area were also collected for population level examinations. Each butterfly and larva was genotyped at the Pgi locus. The MRR data was parameterised with two mathematical models of migration: the Virtual Migration Model (VM) and the spatially explicit diffusion model. VM model predicted and observed numbers of emigrants from populations with high and low frequencies of Pgi-f were compared. Posterior predictive data sets were simulated based on the parameters of the diffusion model. Lack-of-fit of observed values to the model predicted values of several descriptors of movements were detected, and the effect of Pgi genotype on the deviations was assessed by randomizations including the genotype information. This study revealed a possible difference in the effect of Pgi genotype on migration propensity between the two sexes in the Glanville fritillary. The females with and males without the Pgi-f allele moved more between habitat patches, which is probably related to differences in the function of flight in the two sexes. Females may use their high flight capacity to migrate between habitat patches to find suitable oviposition sites, whereas males may use it to acquire mates by keeping a territory and fighting off other intruding males, possibly causing them to emigrate. The results were consistent across different movement descriptors and at the individual and population levels. The effect of Pgi is likely to be dependent on the structure of the landscape and the prevailing environmental conditions.

Anger is associated with subclinical atherosclerosis in low SES but not in higher SES men and women

We investigated the associations of anger and cynicism with carotid artery intima-media thickness (IMT) and whether these associations were moderated by childhood or adulthood socioeconomic status (SES). The participants were 647 men and 893 women derived from the population-based Cardiovascular Risk in Young Finns Study. Childhood SES was measured in 1980 when the participants were aged 3-18. In 2001, adulthood SES, anger, cynicism, and IMT were measured. There were no associations between anger or cynicism and IMT in the entire population, but anger was associated with thicker IMT in participants who had experienced low SES in childhood. This association persisted after adjustment for a host of cardiovascular risk factors. It is concluded that the ill health-effects of psychological factors such as anger may be more pronounced in individuals who have been exposed to adverse socioeconomic circumstances early in life.

Credit Default Swaps and Insurance: Against the Potts Opinion

Little attention has been given to the possibility that CDS transactions might be construed as insurance contracts in English law. This article challenges the widespread “Potts opinion”, which states that CDSs are not insurance, because they do not require the protection buyer to sustain a loss or to have an insurable interest in the subject matter. CDSs often do provide protection against loss that the buyer is exposed to; loss indemnity is not a necessary characterisation of an insurance contract; insurable interest does not form part of the definition of insurance, but is an additional requirement of valid insurance; and what matters is the substance not the form of the contract. The situation in the US and Australia is also briefly considered.
