BETWEEN TWO FIRES: THE ORIGINS OF SETTLER COLONIALISM IN THE UNITED STATES AND FRENCH ALGERIA By Ashley Sanders A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of History – Doctor of Philosophy 2015 ! ABSTRACT' ! BETWEEN TWO FIRES: THE ORIGINS OF SETTLER COLONIALISM IN THE UNITED STATES AND FRENCH ALGERIA By Ashley Sanders This dissertation is a comparative study of the establishment of settler colonies in the American Midwest (1778-1795) and French colonial Algeria (1830-1848). It examines how interactions between the Indigenous populations, colonists, colonial administrators, the military, and the métropole shaped their development and advances the theory of settler colonialism. This study centers on the first fifteen to twenty years of conquest/occupation in the American Midwest, focusing specifically on southern Illinois and Indiana, and the province of Constantine, Algeria. Despite differences in geography, relative size of the military presence and Indigenous demographics, the process of establishing settler colonies in both locations followed similar trajectories.

Q fever is a zoonotic disease caused by the rickettsia-like Coxiella burnetii and leads to abortions and decreased reproductive performances in domestic ruminants. A serological survey, using ELISA test, was conducted to assess the prevalence of this infection in 226 ewes belonging to 39 flocks localized in Constantine (North-eastern Algeria).

  • Algeria: Fear of Islamic Terrorist Groups
    Country Policy and Information Note Algeria: Fear of Islamic terrorist groups Version 1.0 August 2017 Preface This note provides country of origin information (COI) and policy guidance to Home Office decision makers on handling particular types of protection and human rights claims. This includes whether claims are likely to justify the granting of asylum, humanitarian protection or discretionary leave and whether – in the event of a claim being refused – it is likely to be certifiable as ‘clearly unfounded’ under s94 of the Nationality, Immigration and Asylum Act 2002. Decision makers must consider claims on an individual basis, taking into account the case specific facts and all relevant evidence, including: the policy guidance contained with this note; the available COI; any applicable caselaw; and the Home Office casework guidance in relation to relevant policies. Country information COI in this note has been researched in accordance with principles set out in the Common EU [European Union] Guidelines for Processing Country of Origin Information (COI) and the European Asylum Support Office’s research guidelines, Country of Origin Information report methodology, namely taking into account its relevance, reliability, accuracy, objectivity, currency, transparency and traceability. All information is carefully selected from generally reliable, publicly accessible sources or is information that can be made publicly available. Full publication details of supporting documentation are provided in footnotes. Multiple sourcing is normally used to ensure that the information is accurate, balanced and corroborated, and that a comprehensive and up-to-date picture at the time of publication is provided. Information is compared and contrasted, whenever possible, to provide a range of views and opinions.

  • Identifying Geospatial Signatures of Al-Qaeda in the Maghreb Abstract Introduction
    Gerby Marks Penn State Final Project Independent Study GEOG 596i Fall 2010 IDENTIFYING GEOSPATIAL SIGNATURES OF AL-QAEDA IN THE MAGHREB ABSTRACT On September 11, 2006, Al-Qaeda lieutenant Al-Zawahiri released a statement officially aligning Algeria’s Islamist militants, the Salafist Group for Preaching and Combat (GSPC) with Al-Qaeda and publicly transformed the GSPC’s identity into Al-Qaeda in the Islamic Maghreb (AQIM). What new agenda of action did the GSPC’s repositioning on Al-Qaeda’s ideological and political terrain and international gaze produce? Two time periods will be addressed: the GSPC’s era of Al-Qaeda allegiance (2003-September 11, 2006) and the AQIM period (September 11, 2006 to present). This analysis will apply geospatial predictive modeling techniques to open source documentation of GSPC and AQIM events in Algeria to inductively discover spatial patterns about the GSPC’s convergence with Al-Qaeda. INTRODUCTION GENERAL ANALYTIC QUESTION What patterns engender the GSPC’s political realignment as a new Al-Qaeda affiliate (AQIM) and their theater of operations after September 11, 2006? As a complementary line of analysis, Maghrebi and COIN analysts suggests that in accordance with the GSPC’s allegiance to Al-Qaeda from 2003 to the time of the official 2006 merger, the group’s network of associations, ideology, and tactics bore the marks of Al-Qaeda (Knight 2009 and Black 2007, 2008). Accordingly, geospatial signatures of attacks committed by AQIM proper and by the GSPC during its years of informal Al-Qaeda influence shall be evaluated and compared in order to consider the extent to which the formal announcement of the new insurgency entity AQIM altered the tactical theater.
