Hundreds of scientific works are devoted to the study of the Tauric Chersonesus, but the problem of chronology and periodization of its ancient history is not sufficiently developed in historiography. Analysis of scientific literature and a number of sources concerning this subject allows to define the chronological framework and to reveal 10 stages of the history of ancient Chersonesos (as a preliminary definition). The early stage, the Foundation and formation of the Polis, is defined from the middle/last third of the VI century (or the first half of the V century BC) to the end of the V century BC. The end of the late-Antique − early-Byzantine (transitional) time in Chersonesos can be attributed to the second half of the VI – first third of the VII centuries ad).

Lateral Variations

The audiofrequency magnetotelluric (AMT) method has been used to study permafrost thickness near Tuktoyaktuk, N.W.T. in the Mackenzie Delta. In the frequency range of 10 Hz–10 kHz the permafrost behaves as a simple resistive layer over a conductive layer. This simple two-layer model can be inverted by asymptotic models to give a unique value for the thickness of the highly resistive frozen layer. In areas of simple layering, these results correlate well with drilling. In areas of sharp lateral variations in resistivity, depths tend to be underestimated. Unlike other electrical methods, AMT is not hampered by the presence of a surface melt layer in the summer if the conductivity–thickness product of this 'active layer' is less than about 0.03 mho (0.03 S).

A suddenly applied electric current is passed through the earth by means of spaced electrodes. The form of the potential transient as it appears outside the current electrodes is studied. The potential transient is extremely rapid and refined methods of recording are necessary. Means for measuring the relative times of the transient potentials received from different points are discussed. A survey taken over a known deep salt dome is shown; anomalous times of the transients are found to exist over the dome. No correlation is seen between the times of the transients and the resistivity as found by ordinary electrical methods.

Currently, much attention is paid to the political aims and influence of Chinese outward investment, especially in developing Africa. This paper attempts to fill the knowledge-gap of international entrepreneurship literature by analyzing the entrepreneurial behavior of Chinese firms under the background of south-south economic cooperation. Through the case studies, we analyze the distinctive entrepreneurial behaviors and characters of different types of Chinese firms with high entrepreneurial spirits in Africa during the transitional time. After comparing the various entrepreneurial behaviors between Chinese and West investors, this paper sheds light on the potential positive roles of the entrepreneurial spirit, high risk-behavior and adaptability to foreign environment, which are necessary to successfully seek new, overseas entrepreneurial opportunities from an emerging market. Applications for firms' managers and policy makers are also offered.
