Hub Location Problem with Allowed Routing between Nonhub Nodes

In this study, we relax one of the general assumptions in the hub location literature by allowing routed flows between nonhub nodes. In hub networks, different flows are consolidated and routed via collection, interhub, and distribution arcs. Due to consolidation, some flows travel long paths despite closeness of their origin and destination. In this study, we allow direct flows by penalizing by a scalar factor of original cost of transshipment between these arcs. We present mathematical models for median, center, and set covering versions of the problem for single‐ and multi‐allocation cases. We test the models with the CAB and TR data sets. We discuss the properties of established direct connections for different models by using another mathematical model where the number of direct flows is bounded and interpret the effect of changes in problem parameters.     

The Rise of the Safavids According to their Old Veterans: Amini Haravi's Futuhat-e Shahi

This article studies an early Safavid chronicle, Futuhat-e Shahi by Amini Haravi. In 1521, the founder of the Safavid state, Shah Isma‘il, provided Haravi with a number of veterans from the early days of the Safavid uprising as informants. Their narrative presents an alternative view on the early career of the shah that differs from the dominant version current in modern scholarship. From the perspective of the Futuhat, the rise of the Safavids did not occur as a wild apocalyptic explosion, but was a carefully planned and cautious campaign run by experienced commanders who kept a tight rein on the teenage Shah Isma‘il.     

Grave‐goods from the long chamber tomb “Dibba 76/1” (Fujairah,UAE): a first inventory

The aim of this paper is to present the rich set of finds collected inside the grave Dibba 76/1, in the Emirate of Fujairah, during a season of rescue excavation conducted under the direction of S. Ali Hassan in 1994. The recovered grave‐goods include pottery, soft‐stone vessels, metal finds, personal ornaments, coins, and other items. Although comparable with other corpuses of material excavated in south‐eastern Arabia, the material of Dibba 76/1 stands out for the inner variety of the different artefacts’ classes and their remarkable chronological heterogeneity. The study of the grave‐goods suggests that Dibba 76/1 was reused over several centuries, showing a strong continuity in the funerary destination of this specific place from the end of the Wadi Suq period (2000–1600 BC) to the first phases of the late pre‐Islamic period (250 BC–AD 400), and the full integration of the area of Dibba in the succession of the various cultural facies known during this long time span.     

When leadership traits meet historic success: Hassan Rouhani and the nuclear deal of 2015

This study aims to show how dispositional characters of political leaders are affected by situational developments during the time‐in‐office. Although newly emerging literature of leadership traits demonstrate that significant events alter leaders’ traits, they mainly focus on the measurement of shocking events on dispositional features, leaving the effect of achievements underexplored. The Iranian nuclear deal of 2015 is one of the most significant successes in the last decade of world politics. Gambling his political career on nuclear talks by promising the Iranian people to solve Iran's decades‐long isolation, President Hassan Rouhani played a momentous role in negotiating the deal. The Joint Comprehensive Plan of Action (JCPOA) was globally recognized as a success of Rouhani's leadership. Using the Leadership Trait Analysis (LTA), this article will show the role of Rouhani's personality in the realization of the historic nuclear deal and measure the effect of such a success on Rouhani's leadership traits.     

The Euro-Arab Dialogue 1973–1978: Britain Reinsurance Policy In The Middle East Conflict

The Euro-Arab Dialogue (EAD) was launched in the aftermath the Arab Israeli Yom Kippur War of 1973 by Nine European countries and the Arabs. The main objective was to create a stable, long-term relationship between the two regions. Despite its political intent, the framework of the Dialogue was restricted to multilateral economic co-operation in selected areas for reciprocal benefits. Due to inevitable obstacles, after almost five years of engagements, the Dialogue seemed to be progressing slowly with the development of only a few practical projects. Nevertheless, the British remained committed to the initiative, which they viewed as supplementary to their successful existing bilateral relationships, as well as an inexpensive but effective way to maintain their political and economic interests in the Arab world. Through historical analysis, this paper examines the British attitude and perspective towards the Dialogue from 1973 to 1978, mainly using archival documents available at the National Archive in England.

Migration and the built environment: a spatial analysis of resettlement in Çeşme,Turkey

At the beginning of the twentieth century, the retreat of the Ottoman Empire caused a massive scale migration in the Aegean regions. This process was furthered by the Treaty of Lausanne (1923) between the Turkish Republic and Greece. Gradually, more than one million people were formally exchanged under the control of the respective national authorities. This study shows that the predictions made by political authorities regarding the expected adaptation and homogenization based on religious affiliations failed to materialize; instead, the process of migration generated its own unique and autonomous processes derived primarily from cultural aspects and social origins. This research examines the materialization of the migrants’ adaptation practices and the spatial transformations in the built environment at both urban and domestic level, in order to indentify spatial and related social conflicts that arose as a result of socio-cultural mixing through a case study of the Çe?me Peninsula, Turkey. The study concludes that the relationship between social space and the physical environment is intertwined, with spatial transformations based on residents’ home of origin, professions and economic prosperity positioned in a clearly defined hierarchy of meaning.
