    Жінка у стереотипному вікторіанському дискурсі (A woman in the victorian female discourse)

    У статті запропоновано підхід до вивчення форми і змісту комунікативного принципу ввічливості у стереотипній мовленнєвій поведінці вікторіанської жінки, якою її уявляли чоловіки-драматурги. Аналіз базується на поняттях стереотипу та увічливості, що уможливлює реконструювання стереотипу жіночої комунікативної поведінки. Встановлено, що позитивна ввічливість домінує в ситуаціях виявлення почуттів, світської бесіди і флірту; в інших ситуаціях варіативність за ситуативним критерієм нейтралізується і залежить від моногендерного чи кросгендерного контексту спілкування. (The article offers an approach to studying the form and content of the communicative politeness principle in the stereotypic communicative behaviour of the Victorian woman as seen by male playwrights. The Victorian woman is a representative of middle/upper classes, the mouthpiece of Victorian mentality, social and cultural norms, the exponent of the language standard of the age. Stereotypic communicative behaviour of the Victorian woman is realised in her discourse dominated by the principle of politeness: positive politeness prevails, and the strategy of raising common ground is given priority to; among negative politeness strategies the strategy of questioning/hedging is the one used most frequently. In the stereotype of her communicative behaviour, the gender parameter has relative importance: positive politeness prevails in the situations of feelings outpouring, small talk, and small talk; in the rest of the situations, politeness strategies variation is neutralised by the situational criterion, it depends on the mono-gender or cross-gender contexts of communication

    Symmetry adapted ro-vibrational basis functions for variational nuclear motion calculations: TROVE approach

    We present a general, numerically motivated approach to the construction of symmetry adapted basis functions for solving ro-vibrational Schr\"{o}dinger equations. The approach is based on the property of the Hamiltonian operator to commute with the complete set of symmetry operators and hence to reflect the symmetry of the system. The symmetry adapted ro-vibrational basis set is constructed numerically by solving a set of reduced vibrational eigenvalue problems. In order to assign the irreducible representations associated with these eigenfunctions, their symmetry properties are probed on a grid of molecular geometries with the corresponding symmetry operations. The transformation matrices are re-constructed by solving over-determined systems of linear equations related to the transformation properties of the corresponding wavefunctions on the grid. Our method is implemented in the variational approach TROVE and has been successfully applied to a number of problems covering the most important molecular symmetry groups. Several examples are used to illustrate the procedure, which can be easily applied to different types of coordinates, basis sets, and molecular systems
