We review recent work clarifying the sense in which the Jahn-Teller effect can exist in a molecular complex in liquid solution. We review the molecular dynamics methods for modeling such liquid systems using the cupric ion in aqueous solution as an example. We review the experimental evidence for the Jahn-Teller effect in liquids, emphasizing the importance of taking the time scale of the measurement into account. Finally we discuss the role of quantum coherence and the Berry phase in the Jahn-Teller effect.

Zeno and anti-Zeno effects in the evolution of the multi-photonic dissociation dynamics of the diatomic molecule HBr[Formula: see text] owing to repeated measurements demand if the system in the initial state have been studied. The effects have been calculated numerically for the case of vibrational population transfer and dissociation dynamics of HBr[Formula: see text] taking it as a model. We use time-dependent Fourier grid Hamiltonian (TDFGH) method as a mathematical tool in presence of intense radiation field as perturbation. The effects have been explored through a probable mechanism of population transfer from the ground vibrational state to the different upper vibrational states which ultimately go to the dissociation continuum. The results show significant differences in the mechanism of population transfer and the significant role of time interval of measurement ([Formula: see text] in Zeno and anti-Zeno effects. In case of survival probability of ground vibrational states, there is Zeno effect when the frequency of the laser to which the molecule is submitted is near the vibrational [Formula: see text] to [Formula: see text] resonance, while there is anti-Zeno effect if it is far from this resonance.

AbstractThis article traces intersections between Turkey's relations with the League of Nations and violent homogenization in Anatolia in the two decades following World War I. It advances the argument that the strife for creating a homogenous population—a core element of Turkish nation building—was embedded in the international order. This is explained on two levels. First, the article stresses the role of international asymmetries on the mental horizon of the Turkish nation builders. The League's involvement in the allied plans to partition Turkey had the organization wrapped up in a mélange of humanitarian concerns, civilizing doctrine, and imperialist interests. Turkish nationalists wanted to avoid those imperialist pitfalls and overcome international minority protection by means of Turkification. They saw international humanitarianism as an obstacle to their nationalist line. Second, the article highlights the ways in which the League itself supported the Kemalists’ drive for Turkification, either directly, especially in the case of the “population transfer” between Greece and Turkey, or indirectly through prioritizing Turkey's sovereignty over minority concerns.

The purpose of this essay is to discuss a number of aspects relating to the client and captive labour force in the Bida emirate in the immediate pre-colonial period. Using data collected in surveys of 1611 captive and client villages in the 1930s, it has been possible to estimate the origins of a large part of this force and to establish the different periods of its recruitment. Comments are made regarding the role of this labour force in the pre-colonial economy of Nupe, on the position of slaves and clients in the society of the emirate, and on the effects of the extensive population transfer on the ethnic demography of Nupeland. It is hoped that this essay will contribute to the contemporary discussion regarding indigenous slavery in Africa, and will lead to an accelerated abandonment of simplistic notions concerning the nature of African economy and society in the late nineteenth century.
