The Transitional Justice and Foreign Policy Nexus: The Inefficient Causation of State Ontological Security-Seeking

How does an approach towards transitional justice produce preconditions for a country’s international action, enabling certain policies and practices in the immediate neighborhood and international society at large? This article unpacks ontological security-seeking as a generic social mechanism in international politics which allows to productively conceptualize the connection between a state’s transitional justice and foreign policies. Going beyond the dichotomy of transitional justice compliance and non-compliance by gauging the role of states’ subjective sense of self in driving their behavior, I develop an analytical framework to explain how state ontological security-seeking relates to major transitions and consequent state identity disjuncture, the ensuing politics of truth and justice-seeking, and its international resonance in framing and executing particular foreign policies. I offer a typology of the international consequences of states’ transitional justice politics, distinguishing between reflective and mnemonical security-oriented approaches, spawning cooperative and conflictual foreign policy behavior, respectively. The empirical purchase of the purported nexus is illustrated with the example of post-Soviet Russia’s limited politics of accountability towards the repressions of its antecedent regime and its increasingly self-assertive and confrontational stance in contemporary international politics

Study of the doubly charmed tetraquark T+cc

Quantum chromodynamics, the theory of the strong force, describes interactions of coloured quarks and gluons and the formation of hadronic matter. Conventional hadronic matter consists of baryons and mesons made of three quarks and quark-antiquark pairs, respectively. Particles with an alternative quark content are known as exotic states. Here a study is reported of an exotic narrow state in the D0D0π+ mass spectrum just below the D*+D0 mass threshold produced in proton-proton collisions collected with the LHCb detector at the Large Hadron Collider. The state is consistent with the ground isoscalar T+cc tetraquark with a quark content of ccu⎯⎯⎯d⎯⎯⎯ and spin-parity quantum numbers JP = 1+. Study of the DD mass spectra disfavours interpretation of the resonance as the isovector state. The decay structure via intermediate off-shell D*+ mesons is consistent with the observed D0π+ mass distribution. To analyse the mass of the resonance and its coupling to the D*D system, a dedicated model is developed under the assumption of an isoscalar axial-vector T+cc state decaying to the D*D channel. Using this model, resonance parameters including the pole position, scattering length, effective range and compositeness are determined to reveal important information about the nature of the T+cc state. In addition, an unexpected dependence of the production rate on track multiplicity is observed

NAPHTHALINE AND DIPHENYLBUTADIENE COMPLEXES OF RARE-EARTH ELEMENTS. SYNTHESIS, STRUCTURE, PROPERTIES

The aim is to investigate the interaction of halogenides of the rare-earth elements with anion-radicals of the naphthaline and diphenylbutadiene, to study the structure and properties of the forming products and also their catalytic activity in the stereospecific polymerization of the isoprene. The high-reaction-able naphthaline complexes for the whole series of the lanthanides have been created. The new synthesis method of the cyclopentadienides processing from nasthaline complexes has been proposed. The new type of the catalystes capable to polymerize stereoregularly the isoprene with high rate without co-catalyst has been proposed. The reduction of the azobenzene with naphthaline samarium complex has been studied. The tetranuclear complex of the samarium with azobenzene and phenylnitre ligands has been made firstly and characterized structurally. The representatives of the new class lanthanide complexes - bis-diphenylbutadiene ate-complex of lutetium and bi-nuclear complex of gadolinium with bridge diphenylbutadiene have been synthesized firstly and characterized structurally. The conclusion about ion nature of these complexes has been made with attachment of the magnetic and designed data.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

THE MECHANICAL PHENOMENA IN THE PROCESSES OF SOLIDIFICATION

Used have been 10 epoxide systems. The purpose of the work: to establish the laws of the shrinkage defect-formation with the solidification under the restrained conditions, near to the isochoric ones. The phenomenon of the shrinkage defect-formation with the isothermal solidification under the restrained conditions has been detected, the new methods of investigation of the shrinkage defect-formation have been developed, the new laws of this phenomenon have been established. The connection with the relaxation transitions in the course of solidification has been shown; the theoretical models of the shrinkage defect-formation (including those in the polymer compostites) have been developed. The recommendations on optimization of the mode of solidification have been given.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
