The aim of this study is to analyze the Islamic Republic of Iran (IRI)'s policy toward and involvement in the African continent as a case study of the IRI's global policy and reach. The aspiration of the IRI's leadership for international standing and support coupled with a desire to export its revolutionary model and extend its influence beyond its borders have shaped its activity on many continents, including Africa. Africa's strategic location, past colonial experience, political position, rich resources, large Muslim population, and economic attractiveness have all contributed to shaping the IRI's activity within it. This study analyzes IRI's foreign policy in general and its implementation in Africa in particular, identifying the different historical phases of its activity in Africa, distinguishing between the various African regions, the main Iranian organizations involved therein, the means of and channels for Iranian involvement in Africa, and the reasons for IRI's gains and losses on that continent. The study shows how the Islamic regime has managed, during its 40 years of rule, through pragmatism and resilience, to gain influence and support, has endeavored to balance its losses, and has adapted to new circumstances in the African continent.  相似文献

Decolonial theorists pose a new challenge to liberation theology: Does its formulation of the option for the poor address the coloniality that distinguishes the modern context? This article argues that an option for the poor within theology, as a decolonial option, has to retrieve and deepen two central concerns of liberation theologians’ early articulation of the option for the poor: (1) the commitment to the poor and the way the divine is manifested historically, and (2) the affirmation of the need for social analysis and the need for this analysis to impact the commitment to God. The article draws on Teología India and womanist theology to indicate how these two interrelated commitments within the option for the poor can strengthen the option for the poor as a decolonial option.  相似文献

River basins are an extremely important source of freshwater for Africa and the impact of climate change on these communities constitutes an important question worth studying. Among these basins, the Niger River Basin is an ideal candidate for meso-level theory testing of climate change-induced political violence because of its importance as one of the largest sources of freshwater in Africa, its high vulnerability to climate change, and its location in a politically unstable region. This paper utilizes the benefits of GIS to test whether effects of water insecurity on the various incidences of political violence are conditional on economic, geographic, and social means of connectivity. Our analysis uses the density of secondary road networks, the geographic distance to the Niger River, and a shared co-ethnicity with one's head-of-state to evaluate the impact of hydrological stress and its subsequent risk for political violence across nine West African countries from 1997 to 2012. Using climatological data and an econometric de-trending method, we measure the separate, substantive impact that individualized changes in precipitation trend and precipitation variability have for the incidence of ACLED's political violence events, conditional on local economic, geographic, and social factors. Our results reveal a complicated web of circumstances under which certain forms of political violence are more/less likely to be observed. The implications of this analysis serve as a call for a closer inspection of the micro-channels by which climate stress impacts heterogeneous communities in the developing world.  相似文献

The aim of this paper is to investigate whether the ceramics from the Goguryeo fortified sites of the Han River region in central Korea were manufactured and consumed locally during the southern expansion of the Goguryeo State (475–551 ce ). For this research, 88 ceramic samples from seven contemporary sites in the southern territories of Goguryeo were sampled and analysed by ceramic thin‐section petrography and neutron activation analysis (NAA). In addition, to establish a possible chemical fingerprint at Hongryeonbong Fort 2, five clay specimens were also gathered and analysed from the pottery firing structure. The results of this analytical study indicate that the majority of the ceramics from the Goguryeo fortified sites of central Korea were produced and circulated within this newly acquired region. In addition, it is highly probable that Hongryeonbong Fort, which contains the remains of what may be ceramic firing architecture, is the place of production for the ceramics.  相似文献

This article explores the levels of fragmentation and fracture patterns in archaeofaunal assemblages from the lower basin of the Colorado River (Argentina) following Outram's methodology. Remains of ungulates (guanaco) have suffered, in these assemblages, a high degree of fragmentation probably caused during the processing of the carcasses. The presence of helical debris and shaft fragments indicates that fragmentation would respond to processing tasks for the consumption of marrow and possibly bone grease. The results of the application of this methodology that were obtained from the analysis of three late Holocene sites (La Primavera, Loma Ruiz 1 and El Tigre) are presented. These results provide new evidence not only for patterns of marrow and bone grease consumption but also for dealing with the subsistence model proposed for the study area. In this sense, the intensification processes already proposed during the final late Holocene (1000–250 bp ) are discussed. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

From AD 1274 Chinese emperor Kublai Khan dispatched fleets of ships in a series of attempts to expand the empire's hegemony and extend his rule into East Asia (Japan) and Southeast Asia (Vietnam, Champa and Java). Archaeological remains associated with the fleets and battles have been found at Takashima Island, Japan and on the B?ch Ð?ng River, Vietnam. This paper develops a thematic approach to these sites within a framework of naval battlefield archaeology. It compares the similarities and differences in environmental conditions and archaeological contexts of the two sites in Japan and Vietnam. It also outlines recent archaeological research conducted between 2008 and 2010 on the physical remains at the B?ch Ð?ng River battlefield site.  相似文献

Traditional scholarly opinion has regarded Kalha?a's Rājatara?gi?ī, the twelfth‐century Sanskrit chronicle of Kashmiri kings, as a work of history. This essay proposes a reinvestigation of the nature of the iconic text from outside the shadow of that label. It first closely critiques the positivist “history hypothesis,” exposing its internal contradictions over questions of chronology, causality, and objectivity as attributed to the text. It then argues that more than an empiricist historical account that modern historians like to believe it is—in the process bracketing out integral rhetorical, mythic, and didactic parts of the text—the Rājatara?gi?ī should be viewed in totality for the kāvya (epic poem) that it is, which is to say, as representing a specific language practice that sought to produce meaning and articulated the poet's vision of the land and its lineages. The essay thus urges momentarily reclaiming the text from the hegemonic but troubled understanding of it as history—only to restore it ultimately to a more cohesive notion of historicality that is consistent with its contents. Toward this end, it highlights the concrete claim to epistemic authority that is asserted both by the genre of Sanskrit kāvya generally and by the Rājatara?gi?ī in particular, and their conception of the poetic “production” of the past that bears a striking resonance with constructivist historiography. It then traces the intensely intertextual and value‐laden nature of the epistemology that frames the Rājatara?gi?ī into a narrative discourse on power and ethical governance. It is in its narrativity and discursivity—its meaningful representation of what constitutes “true” knowledge of time and human action—that the salience of the Rājatara?gi?ī may lie.  相似文献

Several researchers have suggested use of watercraft during the Early Paleoindian period 11,500 and 10,800 rcybp (13,400–12,700 cal B.P.), but none have brought empirical data to bear on this possibility. This paper addresses the potential for fluted point-making groups to have made and used boats circa 11,000 rcybp (13,000–12,800 cal B.P.). Fluted point data from a large region of the upper and central Mississippi River valley strongly suggest that the Mississippi River was a barrier to movement and that Early Paleoindians in the midcontinent did not routinely use watercraft.  相似文献

The Poema de Fernán González is usually regarded as a hybrid text—while its subject matter is deemed epic, its expression, intentionality, and ideology are considered clerical. This article studies several elements shared by Fernán González and the other poems of the mester de clerecía school: the same stanza (the cuaderna vía) and poetic rules; similar modes of composition, transmission, and reception; and common structural, thematic, and verbal patterns. The article concludes that the Poema de Fernán González fully participates in the common artistry of the mester de clerecía and therefore can be regarded as the attempt to produce epic poetry by this learned clerical school.  相似文献
