关于设置《中国屯垦经济史》课程的分析

在中国经济史课程中，屯垦经济史一直是作为农业经济的一个组成部分而占有较小的份量。作为有着屯垦戍边传统地区的高校，尤其需要在中国屯垦经济史教学和研究领域加大力度，特别是建立独立的中国屯垦经济史课程进行教学，这不仅可以使学生了解在两千年来的西北边疆屯垦和戍边史上屯垦经济所发挥的重要作用，而且可以进一步加深其对在国家战略西向中兵团经济发展所具有的重要意义的理解，并且，在课程建设和完善的基础上，逐步突出该课程的地域特色和学习价值，并进一步将其建设成国家的精品课程。     

机构运动弹性动力学普遍方程的研究

本文首次采用等参有限单元,建立了一个为一般机构广泛适用的运动弹性动力学普遍方程。在不附加任何“运动学”假设的情况下,作为自然的结果,方程的质量阵是正定、协调的常数阵;方程中不存在两类时变的非对称系数项,即所谓的“陀螺阻尼”项和“离心动刚度”项。因此,该方程无论在形式上还是在生成及求解方面,都要较其它同类型方程简单。此外,基于一维等参梁单元,本文还具体导出了具有杆状构件的平面连杆机构的弹性动力学模型,并给出了一个铰链四杆机构的算例。     

Socioeconomic impact of conflict: state of emergency ruling in Turkey

Uprising tensions during 2010 in eastern and southeastern regions of Turkey provoked arguments about the necessity for a State of Emergency (SOE; ‘Ola?anüstü Hal’ in Turkish) declaration in those regions, with a belief of enduring political sustainability. The discussion is inflamed by a speech of the Nationalist Movement Party’s leader about the suggestion to announce a SOE ruling after the death of 24 Turkish soldiers in Hakkari (a city in the southeast of Turkey) in an attack of the PKK (Kurdistan Workers’ Party) on the 19 October 2011. Although a new announcement of SOE did not take place, the discussion itself induced the idea behind this paper which is to provide a quantitative analysis of the SOE in Turkey. In fact, the SOE ruling is not a new concept for Turkey and it has been implemented in 13 cities in the eastern and southeastern regions from 1987 to 2002. Although there have been many discussions about the costs of these 15 years of the SOE ruling in terms of military expenditure and, thus, on the national budget, there is a lack of quantitative analytical examination of the economic and social costs of it. Difference-in-differences analysis reveals negative spillover impacts of the SOE, especially on the forced migration, unemployment, and educational investments. The results also show that SOE ruling is an important factor for the underdevelopment of the eastern and southeastern regions in Turkey and, thus, a new SOE will bring enormous inequalities, both economically and socially, and an intensification of the ethnic tensions in Turkey.

The timing of contests

We develop a simple model to analyze the timing of contests. When the odds of winning a contest are exogenously given – we show that if either the players discount the future or if the total cost of contest is smaller in the future – there exist subgame perfect equilibria where both players settle, anticipating a contest in the future. With endogenous efforts, the aggregate efforts expanded in a contest are smaller if the contest occurs in the future when the relative effort productivities remain constant or diverge over time, thus creating scope for delay in contests. When the effort productivities converge over time, the total efforts may be greater under a future contest. As a consequence, players either settle over the two periods, or else they initiate a contest immediately.

Coping with traps of vulnerability: a review of the impact of post-colonial issues on the independence of South Sudan

In a world virtually free of slavery and colonialism and one mainly driven by the sovereign state rationale, allusion to manifestations or the existence of some form of these phenomena within a state is often received with dumbfounding indifference or denial. However, a form of rule that had continued in South Sudan long after the departure of the British in 1956 was colonial both in its quintessence and flair in that it disenfranchised its citizens and denied them the most basic freedoms, services and development. Under this establishment, resistance against the coercive vision of the state was brutally suppressed for many decades. This state of affairs finally ended in July 2011. Nonetheless, there is a miscellany of unresolved post-colonial issues between the two countries that warrant attention. These include security and the demarcation of borders, the issue of ludicrous transit fees for South Sudan's oil exportation through Sudan, citizenship, external debt repayment, etc. These issues are part of traps inherited from the anti-colonial struggle, which have now supplanted the old ensemble of North–South conflict paroxysm. As a matter of urgency, the two countries will have to wrap up the incomplete process of negotiation on these substantive issues. The talks should be approached with a new mindset based on the new reality of two sovereign states. To the extent that it is widely established that South Sudan and Sudan must coexist peacefully in order to develop into viable entities, such mutual dependency must be based on equality and respect.     

Intelligence reform and the transformation of the state: the end of a French exception

ABSTRACT

This article argues that the intelligence sector is a privileged vantage point to observe and analyse a transformation of the State in France, as this transformation deeply affects the heart of the executive power and the French intelligence and security apparatus. Traditionally, intelligence was not conceived in France as a functional tool in the hands of the decision-maker but was rather defined as a ‘regalian power’. Intelligence activities were derived from a very specific conception of the State, and especially the particular notion of ‘reason of State’ (raison d’État). The current intelligence reform prompts speculation as to whether it represents more than a ‘simple’ functional reorganisation or in fact could signify that intelligence is now recognised as a tool in the hands of a ‘État de droit’ (‘liberal state’). The idea of a French ‘exceptionalism’ is addressed through a theoretical approach of the way France redefines intelligence and surveillance in relation with a major evolution of the notion of ‘reason of State’ itself. Then the article illustrates the assumption of a ‘lost tradition’ of reason of State through an analysis of the current reform of the intelligence sector in France. This reform is based on processes of rationalisation, centralization, modernisation and normalisation of both intelligence activities and intelligence services in France. As a conclusion, the article addresses the reactions to the January and November 2015 terrorist attacks in Paris, and asks whether resilience towards terrorism requires to accelerate the pace of the transformation of the French intelligence sector.
