  • The Socioeconomics of State Formation in Medieval Afghanistan
    The Socioeconomics of State Formation in Medieval Afghanistan George Fiske Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2012 © 2012 George Fiske All rights reserved ABSTRACT The Socioeconomics of State Formation in Medieval Afghanistan George Fiske This study examines the socioeconomics of state formation in medieval Afghanistan in historical and historiographic terms. It outlines the thousand year history of Ghaznavid historiography by treating primary and secondary sources as a continuum of perspectives, demonstrating the persistent problems of dynastic and political thinking across periods and cultures. It conceptualizes the geography of Ghaznavid origins by framing their rise within specific landscapes and histories of state formation, favoring time over space as much as possible and reintegrating their experience with the general histories of Iran, Central Asia, and India. Once the grand narrative is illustrated, the scope narrows to the dual process of monetization and urbanization in Samanid territory in order to approach Ghaznavid obstacles to state formation. The socioeconomic narrative then shifts to political and military specifics to demythologize the rise of the Ghaznavids in terms of the framing contexts described in the previous chapters. Finally, the study specifies the exact combination of culture and history which the Ghaznavids exemplified to show their particular and universal character and suggest future paths for research.

This work; encompassing several papers and various chapters of my book are attached behind this essay. The research question, examines the effect of Western support to warlords on political legitimacy in the post 9/11 Afghan war. I contextualise the research question in terms of my critical engagement with the literature of strategists in Afghanistan during this time. Subsequently, I draw out themes in relation to the available literature on warlords, politics and security in Afghanistan. I highlight the value of thinking about these questions conceptually in terms of legitimacy. I then introduce the published work, summarising the focus of each paper or book chapter. Later, a ‘findings’ section addresses how the policy of supporting warlords has affected legitimacy through its impact on security and stability, the political settlement and ultimately whether Afghans choose to accept the Western-backed project in Afghanistan, or not.

In view of the sampling techniques employed in the present investigations, elect rical conductivity and temperature are found to be the best fie! d parameters for a quick estimate of mixing path length. However, the stable isotopes of the water molecule, due to their greater sensitivity and measuring accuracy, provide a better scenario of the mixing characteristics as compared to the physico-chemical parameters.

The origin of my study extends beyond the moment I had to pick a research topic for completion of my doctoral dissertation in the Department of Anthropology, Indiana University. This study grapples with some questions that have occupied my mind since a young age when my parents decided to migrate from Kabul to Los Angeles because of the Soviet-Afghan War of 1980s. I undertook sections of this topic while finishing my Senior Project at UC Santa Barbara and my Master’s thesis at California State University, Fullerton. I can only hope that the questions and analysis offered here reflects my intellectual progress.

  • Investigation of Isotopes and Hydrological Processes in Indus River System, Pakistan
    PINSTECH- 215 INVESTIGATION OF ISOTOPES AND HYDROLOGICAL PROCESSES IN INDUS RIVER SYSTEM, PAKISTAN Manzoor Ahmad Zahid Latif Jamil Ahmad Tariq Waheed Akram Muhammad Rafique . Isotope Application Division Directorate of Technology Pakistan Institute of Nuclear Science and Technology P.O. Nilore, Islamabad, Pakistan November, 2009 ABSTRACT Indus River, one of the longest rivers in the World, has five major eastern tributaries viz. Bias, Sutlej, Ravi, Chenab and Jhelum) while many small rivers join it from the right side among which Kabul River is the biggest with its main tributaries, the Swat, Panjkora and Kunar. All these main rivers are perennial and originate from the mountains. Basic sources of these rivers are snowmelt, rainfall and under certain conditions seepage from the formations. Different water sources are labeled with different isotope signatures which are used as fingerprints for identifying source and movement of water, geochemical and/or hydrological processes, and dynamics (age of water). Monitoring of isotopes in rivers can also enhance understanding of the water cycle of large river basins and to assess impacts of environmental and climatic changes on the water cycle. Therefore, a national network of suitable stations was established for isotopic monitoring of river waters in Indus Basin with specific objectives to study temporal variations of isotopes (2H, 18O and 3H), understand water cycles and hydrological processes in the catchments of these rivers, and to develop comprehensive database to support future isotope-based groundwater studies in the basin on recharge mechanism, water balance and monitoring of ongoing environmental changes. Water samples were collected during 2002-2006 on monthly basis from more than 20 stations at the major rivers and analyzed for 18O, 2H and 3H isotopes.
