This paper empirically investigates the importance of financial and political variables in determining debt rescheduling probabilities in Turkey for 1955–2000. The problem of sovereign debt default and rescheduling has been the subject of substantial academic research during the last two decades. There has been criticism of models of developing countries’ indebtedness and rescheduling that rely solely on some economic or financial predictors related to country debt, the foreign exchange sector or the domestic economic situation. Using probit analysis, this paper indicates that financial variables are important determinants of rescheduling probabilities. However, political variables are not significant in our models. 相似文献

By way of an evolutionary game model we show that mediation in international conflicts might be harmful to the conflicting parties. In fact, under anarchy both parties can be better off than under an international regime if mediation reduces the parties’ reactive capacities (i.e. their abilites to respond to an aggression). This result is applied to issues currently discussed in the literature on international relations such as the role of the United Nations as a mediator of international conflicts. 相似文献

This article presents the results of an empirical survey of Slovenian defence enterprises focusing on three segmented geographic market outlets: the domestic market, the other European Union (EU-26) markets and the global markets. In the enterprise surveys are included around two-thirds of the domestic defence enterprises of different sizes and activities. The Slovenian defence enterprises by production, supply-in-return, subcontracting, middleman and trader activities in the defence marketing chains are mostly specializing towards the businesses on the domestic market. Rare enterprises are specialized exclusively for activities on the EU-26 markets and the global markets. 相似文献

Knowledge of early Dublin gunmakers is limited, mainly due to the destruction of records during the Civil War of the 1920s. This article focuses on an early pair of rifled turn-off pistols by Thomas Fitzpatrick and presents new research recently carried out by the author on this little-known gunmaker. 相似文献

A 2‐dimensional rectangular k‐within‐consecutive‐(r, s)‐out‐of‐(m, n):F system consists of m × n components, and fails if and only if k or more components fail in an r × s submatrix. This system can be treated as a reliability model for TFT liquid crystal displays, wireless communication networks, etc. Although an effective method has been developed for evaluating the exact system reliability of small or medium‐sized systems, that method needs extremely high computing time and memory capacity when applied to larger systems. Therefore, developing upper and lower bounds and accurate approximations for system reliability is useful for large systems. In this paper, first, we propose new upper and lower bounds for the reliability of a 2‐dimensional rectangular k‐within‐consecutive‐(r, s)‐out‐of‐(m, n):F system. Secondly, we propose two limit theorems for that system. With these theorems we can obtain accurate approximations for system reliabilities when the system is large and component reliabilities are close to one. © 2005 Wiley Periodicals, Inc.

用常规探头对22SiMn2TiB装甲钢与TWE312异种钢焊接接头进行缺陷检测,杂波和伪缺陷波导致灵敏度、信噪比不高。用扫描电镜观察到这种异种钢焊接接头主要为奥氏体+铁素体组织,其中奥氏体是主体组织。根据焊缝的组织特点,设计出了2.5P13×13K1.5型专用探头。在预制缺陷的焊接接头上进行了验证试验,结果表明2.5P13×13K1.5探头对接头内部的缺陷具有较高的检出率。 相似文献

In this article, we study reliability properties of m‐consecutive‐k‐out‐of‐n: F systems with exchangeable components. We deduce exact formulae and recurrence relations for the signature of the system. Closed form expressions for the survival function and the lifetime distribution as a mixture of the distribution of order statistics are established as well. These representations facilitate the computation of several reliability characteristics of the system for a given exchangeable joint distribution or survival function. Finally, we provide signature‐based stochastic ordering results for the system's lifetime and investigate the IFR preservation property under the formulation of m‐consecutive‐k‐out‐of‐n: F systems. © 2011 Wiley Periodicals, Inc.
