The Relationship

The bridging of the Hellespont by Xerxes was a unique achievement. How was it done? The Chorus of Elders in Aeschylus' Persians expressed their wonder at ‘the flax-bound raft’, and Herodotus described the construction of the two bridges, each with warships as pontoons, with cables well over a kilometre long, and with a roadway capable of carrying a huge army. Classical scholars have generally found these accounts inadequate and even inexplicable, especially in regard to the relationship between the pontoons and the cables. The Hellespont has strong currents which vary in their direction, turbulent and often stormy waters, and exposure to violent winds, blowing sometimes from the Black Sea and sometimes from the Mediterranean. How were the warships moored in order to face the currents and withstand the gales? Did the warships form a continuous platform, or was each ship free to move in response to weather conditions? What was the function of the enormous cables? How and where were they made? Did they bind the pontoons together? Did they carry the roadway? How were they fixed at the landward ends? This article attempts an answer to these questions through the collaboration of a classical scholar and a mechanical engineer.

Release Processes

This article considers the relationship between law, diplomacy, and identity in delineating slavery and freedom in the Black Sea imperial milieu. Examining the release processes for captives which followed each of the many wars between the Ottoman and Russian empires in the eighteenth century, I argue that these matters were increasingly handled according to written and unwritten legal understandings, rather than through ransoms or threats. The two empires agreed that the Ottoman state would set free enslaved Russian subjects, even those in private hands, but also that the Russians would not demand the release of others. This discussion, therefore, offers a window on the legalization of international relations, and on the growing importance of individuals’ relationship with central states. Moreover, these understandings endured, consciously or unconsciously, into the nineteenth century, arguably shaping Russo-Ottoman and Ottoman-European relations on issues of intervention and the slave trade.

The Relationship

Abstract:This study examines the price level and volatility interaction between international staple food and cash crop futures price indices. Understanding the relationship between these commodities bears significant implications for low-income food deficit countries that depend on cash crops to finance food import bills. We use a wavelet analysis to decompose the price indices and then apply a BEKK-MGARCH (Baba, Engle, Kraft and Kroner–multivariate generalized autoregressive conditional heteroskedasticity) approach to analyze the relationship across timescales. Results indicate the level of correlation and volatility linkages are strongest at lower frequencies (longer run) than at higher timescales (short run), with information running from staple food to cash crop markets.

A combined multinomial pricing model is proposed for pricing mining concession in which the annualized volatility of the price of mineral products follows a multinomial distribution. First, a combined multinomial pricing model is proposed which consists of binomial pricing models calculated according to different volatility values. Second, a method is provided to calculate the annualized volatility and the distribution. Third, the value of convenience yields is calculated based on the relationship between the futures price and the spot price. The notion of convenience yields is used to adjust our model as well. Based on an empirical study of a Chinese copper mine concession, we verify that our model is easy to use and better than the model with constant volatility when considering the changing annualized volatility of the price of the mineral product.

Otolith Size

Relations between fish size and otolith size of stargazer (Uranoscopus scaber) were studied in this study. A total of 268 samples were obtained from the coastal shelf of Ordu Province (south-eastern Black Sea) by commercial trawling and gillnetting operations. It was found that there were high correlations between fish size and otolith size. It was concluded that all measurable body sizes could be effectively used to estimate otolith length, width and weight. Similarly, estimation of the age of fish from otolith length and weight was also possible with high significance. The results of this research will be useful for others working on this fish, being a first study in the field. The ages of stargazer were determined between 0+ and 4+. Relationships were determined as OW = 0.001 × OWi2.76, OW = 0.35 × 10−3 × OL2.54 with high correlation coefficients of r = 0.965 and r = 0.949, respectively.

The Relationship

The main purpose of this article is to study the relationship between the spot and future price of European emissionallowances in order to test market efficiency hypothesis and determine which price leads the price discovery process.The work consists of several parts: presentation of theoretical background of model cost of carry; validation of cost of carrymodel assumptions; analysis of price development and conclusion.The cost of carry and cointegration theory is provided as well as overview of the related literature and existing research.The empirical examination reveals structural breaks in data and evidence that spot and futures prices are linked by the cost-ofcarryapproach in the second half of the analysed period. The examination of price development in the market indicated futures price leadership.Conclusion summarized the main results of the performed research.
