Yaḥyā Dawlatābādī’s Contribution to Persian Poetic Modernity

In 1912, Ya?yā Dawlatābādī composed two poems, the form of which diverged greatly from the canonical rules of tradition. Both poems were based on syllabic meters. Critics and historians of modern Persian literature have given these poems little consideration, and discussed them merely from the point of view of metrics. When compared to the great modernist endeavors in the poetry of the time, these pieces were judged severely, or altogether disavowed. This paper aims to show that, beyond mere metrical audacity, Ya?yā Dawlatābādī’s syllabic poems were in fact innovative. As the article argues, they were born out of the same quest for fresh poetic forms that induced contemporaneous modernists to create new, individualized poetic patterns.     

Consequences of Displacement after the Gulf Crisis: A Study of the Responses of 207 Displaced Palestinian and Jordanian Workers

Throughout the war period and immediately thereafter, punitive measures were instituted against Jordanian nationals working in the Gulf; hundreds of thousands were dismissed from their jobs without compensation, and many more were expelled from the Gulf, leaving behind personal belongings, as well as bitter memories. The purpose of this study is to: (1) investigate the effects of the Gulf Crisis on the amount of annual contributions to Jordan's economy by Gulf workers; (2) measure the amount of property loss incurred by Gulf workers as a result of the displacement; (3) examine the duration of unemployment caused among the displaced workers; and (4) measure attitudinal changes among the displaced workers regarding their economic future and the future of Jordan's economy.     

A Theory of Reduplication: Eightfold Meters in Classical Persian Poetry

It is a known fact that classical Persian poets were partial to poetic meters composed of eight feet, known as muthamman. On this topic, however, two issues remain unsolved: How did the Persian poets devise these meters in the first place? Despite their flagrant predilection for eightfold meters, why did the Persians never use such meters as sarī? and qarīb in this form? This paper argues that the Persians, influenced by the structure of the Arabic eightfold base meters, crafted their muthamman meters after a specific process of reduplication. This theory also accounts for the lack of eightfold sarī? and qarīb meters, their structure being incompatible with the reduplication process.     

Obsidian sources in highland Yemen and their relevance to archaeological research in the Red Sea region

The Red Sea and surrounding area formed through dynamic uplift and rifting of Afro-Arabia, and associated volcanism (both oceanic and continental in character). As a result, volcanic landforms and products are widespread and play a vital role in the natural and cultural landscapes of humans occupying the highlands and lowlands on both sides of the Red Sea. Archaeologists have suggested for some time that Afro-Arabian trade in obsidian had its roots in the prehistoric period and that the region was very likely the source of an abundance of obsidian artefacts found as far afield as Egypt, the Persian Gulf and Mesopotamia, and which do not match the well-known Anatolian, Transcaucasian or Mediterranean sources. Nonetheless, the southern Red Sea is one of the few obsidian-rich regions exploited in antiquity that has been barely investigated. In this paper, we highlight new geochemical analyses (carried out by LA-ICP-MS) of obsidian sources in Southern Arabia and beyond, that enhance our knowledge of obsidian exploitation from as early as the Neolithic period, and which enable us to evaluate the role that highland Yemen obsidian sources played in prehistoric long-distance trade. In addition, we present new evidence for explosive volcanic eruptions that likely affected the highland populations of Yemen in the 4th millennium BC.     

On-line Model Updating in Hybrid Simulation Tests

Hybrid simulation has emerged as a relatively accurate and efficient tool for the evaluation of structural response under earthquake loading. In conventional hybrid simulation the response of a few critical components is obtained by testing while the numerical module is assumed to follow an analytical idealization. Where there is a much larger number of analytical components compared to the experimental parts, the overall response may be dominated by the idealized parts hence the value of hybrid simulation is diminished. It is proposed to modify the material constitutive relationship of the numerical model during the test, based on the data obtained from the physically tested component. An approach based on genetic algorithms is utilized as an optimization tool to identify the constitutive relationship parameters used in updating the numerical model. The proposed model updating approach is verified through two analytical examples of steel and reinforced concrete frames. The results show the effectiveness of the updating process in minimizing the errors, compared to the assumed exact solution.
