Language attitudes and religion: Kurdish Alevis in the UK

In this article I report on results of a Matched Guise Tests (MGT) study investigating attitudes towards Bohtan (BHKr) and Maraş Kurmanji (MRKr) spoken among the UK diaspora. I focus on BHKr, which I use to refer to the Kurmanji that is identified as “good Kurmanji”, also referred to as “academic”/ “proper”, and MRKr to refer to the Kurmanji that is referred to as “bad Kurmanji” by Kurmanji speakers in the UK (Author 2018). The MGT, and questions pertaining to perceptual dialectology such as respondents’ perceptions of region, religion, gender and class in this study, show that attitudes towards what is perceived as BHKr and MRKr differ significantly. By concentrating on language attitudes towards Kurmanji which have never been studied in the UK context before, this paper investigates negative and positive evaluations of both BHKr and MRKr in relation to religious affiliation

Multi-Nucleon Exchange in Quasi-Fission Reactions

Nucleon exchange mechanism is investigated in the central collisions of ${}^{40}$Ca + ${}^{238}$U and ${}^{48}$Ca + ${}^{238}$U systems near the quasi-fission regime in the framework of the Stochastic Mean-Field (SMF) approach. Sufficiently below the fusion barrier, di-nuclear structure in the collisions is maintained to a large extend. Consequently, it is possible to describe nucleon exchange as a diffusion process familiar from deep-inelastic collisions. Diffusion coefficients for proton and neutron exchange are determined from the microscopic basis of the SMF approach in the semi-classical framework. Calculations show that after a fast charge equilibration the system drifts toward symmetry over a very long interaction time. Large dispersions of proton and neutron distributions of the produced fragments indicate that diffusion mechanism may help to populate heavy trans-uranium elements near the quasi-fission regime in these collisions

Nucleon exchange in heavy-ion collisions within stochastic mean-field approach

Nucleon exchange mechanism is investigated in deep-inelastic symmetric heavy-ion collisions in the basis of the Stochastic Mean-Field approach. By extending the previous work to off-central collisions, analytical expression is deduced for diffusion coefficient of nucleon exchange mechanism. Numerical calculations are carried out for ${}^{40}$Ca + ${}^{40}$Ca and ${}^{90}$Zr + ${}^{90}$Zr systems and the results are compared with the phenomenological nucleon exchange model. Also, calculations are compared with the available experimental results of deep-inelastic collisions between calcium nuclei.Comment: 8 pages, 7 figure

Computation of option greeks under hybrid stochastic volatility models via Malliavin calculus

This study introduces computation of option sensitivities (Greeks) using the Malliavin calculus under the assumption that the underlying asset and interest rate both evolve from a stochastic volatility model and a stochastic interest rate model, respectively. Therefore, it integrates the recent developments in the Malliavin calculus for the computation of Greeks: Delta, Vega, and Rho and it extends the method slightly. The main results show that Malliavin calculus allows a running Monte Carlo (MC) algorithm to present numerical implementations and to illustrate its effectiveness. The main advantage of this method is that once the algorithms are constructed, they can be used for numerous types of option, even if their payoff functions are not differentiable.Comment: Published at https://doi.org/10.15559/18-VMSTA100 in the Modern Stochastics: Theory and Applications (https://www.i-journals.org/vtxpp/VMSTA) by VTeX (http://www.vtex.lt/
