Monetary and Fiscal Policies in Bulgaria: Lessons from the Historical Record
No full textThere are two aspects through which an economic policy can influence the economic situation – monetary and fiscal. Monetary and fiscal policies have different and sometimes controversial goals to achieve by means of specific instruments. While the mission of central banks is generally price stability, governments usually set their goals in the realm of economic growth and employment. Fiscal institutions , however, often use inflation in order to derive revenues (seigniorage) and finance budget deficits. Hence, inflation is viewed as a public finance phenomenon (Barro, 1979; Mankiw, 1987; Grilli, 1989). The purpose of this paper is to present a historical perspective on the behaviour of the monetary and fiscal policies pursued in Bulgaria from 1879, when the Bulgarian National Bank was established (soon after the liberation from the Ottoman Empire). Furthermore, historical time series of monetary and fiscal indicators give us the chance to study the link between government budget problems, fluctuations of monetary variables and inflation dynamics in different monetary episodes.monetary and fiscal policy, inflation, exchange rate

Multiple Social Identities in Relation to Self-Esteem of Adolescents in Post-communist Albania, Bulgaria, the Czech Republic, Kosovo, and Romania
No full textWe test a model linking ethnic, familial, and religious identity to self-esteem among youth in Albania, Bulgaria, the Czech Republic, Kosovo, and Romania. All countries are post-communist nations in Europe, offering novel and underexplored settings to study identity. Participants were 880 adolescents (mean age, 15.93 years; SD, 1.40) with Albanian (n = 209), Bulgarian (n = 146), Czech (n = 306), Kosovan (n = 116), and Romanian (n = 103) background who filled in an Ethnic Identity Scale (Dimitrova et al., 2016), familial and religious identity scales adapted from the Utrecht Management of Identity Commitment Scales [U-MICS; Crocetti et al. Child and Youth Care Forum, 40, 7–23 (2011); Crocetti et al. Assessment, 1, 2–16 (2015)], and the Rosenberg’s Self-Esteem Scale [Rosenberg, Conceiving the self. Basic Books, New York (1979)]. A multigroup path model showed that ethnic, familial, and religious identities were significantly positively related to a single underlying construct of social identities. In all countries, youth with a stronger multiple identities reported higher self-esteem. These results are particularly valuable in addressing the scope of the proposed book by providing new knowledge on multiple social identities among under investigated samples from post-communist countries in Europe faced with dynamic societal changes. They also mirror increasing attention on multiple, inclusive, and intersectional identities as psychological assets for young generations
What a Difference Context Makes: Comparing Communication Strategies of Migration NGOs in Two Neighboring Countries
No full textThis research study compared non-governmental organizations (NGOs) working in the area of migration in two neighboring countries – Bulgaria and Turkey. Utilizing in-depth interviews with 39 NGO professionals in both countries, the analysis identified critical differences in public opinion dynamics, organizational structures and interdependencies, and government relationships. Further analysis unveiled how the local socio-economic and political context had impacted NGO communication strategies as well as the specific communication channels, public engagement activities, and social media campaigns in each country. Implications for communication scholarship during times of increasing migration flows and globalization are discussed.This article is published as Dimitrova, D., Ozdora-Aksak, E., What a Difference Context Makes: Comparing Communication Strategies of Migration NGOs in Two Neighboring Countries.

Prompt charm production in pp collisions at √<span style="text-decoration:overline">s</span>=7 TeV
No full textCharm production at the LHC in pp collisions at s√=7 TeV is studied with the LHCb detector. The decays D0→K−π+, D+→K−π+π+, D⁎+→D0(K−π+)π+, D+s→ϕ(K−K+)π+, Λ+c→pK−π+, and their charge conjugates are analysed in a data set corresponding to an integrated luminosity of 15 nb−1. Differential cross-sections dσ/dpT are measured for prompt production of the five charmed hadron species in bins of transverse momentum and rapidity in the region 0<pT<8 GeV/c and 2.0<y<4.5. Theoretical predictions are compared to the measured differential cross-sections. The integrated cross-sections of the charm hadrons are computed in the above pT-y range, and their ratios are reported. A combination of the five integrated cross-section measurements gives

where the uncertainties are statistical, systematic, and due to the fragmentation functions
Measurements of the absolute branching fractions for D-s(+) -> eta e(+)nu(e) and D-s(+) -> eta ' e(+)nu(e)
No full textBy analyzing 482 pb(-1) of e(+)e(-) collision data collected at root s = 4.009 GeV with the BESIII detector at the BEPCII collider, we measure the absolute branching fractions for the semileptonic decays D-s(+) -> eta e(+)nu(e) and D-s(+) -> eta ' e(+)nu(e) to be B(D-s(+) -> eta e(+)nu(e)) = (2.30 +/- 0.31 +/- 0.08)% and B(D-s(+) -> eta ' e(+)nu(e)) = (0.93 +/- 0.30 +/- 0.05)%, respectively, and their ratio B(D-s(+) -> eta ' e(+)nu(e)) / B(D-s(+) -> eta ' e(+)nu(e)) = 0.40 +/- 0.14 +/- 0.02, where the first uncertainties are statistical and the second ones are systematic. The results are in good agreement with previous measurements within uncertainties; they can be used to determine the eta-eta' mixing angle and improve upon the D-s(+) semileptonic branching ratio precision
Towards automated knowledge-based mapping between individual conceptualisations to empower personalisation of Geospatial Semantic Web
No full textGeospatial domain is characterised by vagueness, especially in the semantic disambiguation of the concepts in the domain, which makes defining universally accepted geo- ontology an onerous task. This is compounded by the lack of appropriate methods and techniques where the individual semantic conceptualisations can be captured and compared to each other. With multiple user conceptualisations, efforts towards a reliable Geospatial Semantic Web, therefore, require personalisation where user diversity can be incorporated. The work presented in this paper is part of our ongoing research on applying commonsense reasoning to elicit and maintain models that represent users' conceptualisations. Such user models will enable taking into account the users' perspective of the real world and will empower personalisation algorithms for the Semantic Web. Intelligent information processing over the Semantic Web can be achieved if different conceptualisations can be integrated in a semantic environment and mismatches between different conceptualisations can be outlined. In this paper, a formal approach for detecting mismatches between a user's and an expert's conceptual model is outlined. The formalisation is used as the basis to develop algorithms to compare models defined in OWL. The algorithms are illustrated in a geographical domain using concepts from the SPACE ontology developed as part of the SWEET suite of ontologies for the Semantic Web by NASA, and are evaluated by comparing test cases of possible user misconceptions

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
