Is clicking ‘Like’ on Facebook a legitimate form of political participation? Is changing your profile picture or sharing an online article politically meaningful? It is undeniable that such actions can be politically-themed, but whether they amount to what we term ‘political participation’ remains contentious. This article explores the legitimacy of clicktivism as a political act, arguing that legitimacy be understood as multifaceted. To this end, the paper develops a series of lenses by which to explore the theoretical boundaries of these emerging actions. These are: the adherence of the action to tradition avenues; the acceptance of the action, and belief in that action; and, the intentionality of the action, and the context in which it is situated. 相似文献

Ostrich eggshell (OES) beads are an important kind of human ornaments, because their production reflects the development of modern human behavior, thinking ability, and cognitive level. Although the manufacture procedure of OES beads has been reconstructed in some Later Stone Age sites and early Neolithic sites, little information is known about detailed drilling technologies. In this study, synchrotron radiation micro-CT (SR-μCT) was firstly used to scan OES beads to understand microstructure, drilling marks, and perforation shape in a non-destructive mode. In contrast to other method to research drilling technologies, SR-μCT has a unique advantage that it could eliminate the influence of the adhering soils in a perforation in case that they are not easily removed. The results indicate that (1) SR-μCT could differentiate the eggshell species between Struthio camelus and Struthio anderssoni in terms of pore distribution. Compared to other destructive methods, including the anatomical method, DNA and protein analysis, the species identification through SR-μCT is non-destructive and faster; (2) the outer and inner surface of OES could be non-destructively judged according to OES microstructure, which would help infer the drilling direction; and (3) the perforation shape and drilling marks are distinct between the discontinuous twisting drilling and the multi-rotary drilling methods on the basis of replication experiments. According to these criteria, SR-μCT was applied to examine OES beads found in Locality 12 of the Shuidonggou (SDG) site in China, which were probably discarded in 1.1 k yr BP. The results show that most of ancient beads were firstly drilled from inside. According to the perforation shape and drilling marks, both the twisting drilling and the multi-rotary drilling method with different kinds of drill bits were used in working beads. Therefore, the people in SDG site mastered a few drilling technologies in the early Holocene, and the use of the multi-rotary drilling method reflects the technical development of ancient people. Up to our knowledge, it is the earliest known evidence of the application of the multi-rotary drilling method in China. Furthermore, this study will provide a new approach and important reference to understand drilling technologies of much older OES beads in the Later Stone Age or Upper Paleolithic Age. 相似文献

An analysis of terms, and keywords that have appeared over the last 50 years in the Anthropological Index (now AIO) challenges anthropology's purported universal coverage of regions and topics. Anthropological article production published in specialized periodicals leaves many areas uncovered, some topics marginalized, or absent. The article takes the presence or absence of keywords in articles in anthropological literature from all world regions to ask what may have generated these gaps. We argue that keyword use can reveal the role that geographical positioning, languages spoken, and national histories may have had in anthropological production. Shamanism and cognate concepts such as animism and spirit possession are taken to guide an analysis of the anthropological production in different languages through the use of keywords that appear in the coverage of AIO. The research demonstrates how far keywords use is shaped by contingent adjustments to predicaments and theoretical concerns with complex historical roots. 相似文献

Guy Weadick was the American founder of the Calgary Stampede in 1912. By 1930, due to Weadick's vision and promotional genius, the Calgary Exhibition and Stampede (two events having merged by then) was internationally recognized as the premier event of its type in the world. Then, with dramatic suddenness, Weadick was fired in 1932. This article suggests that the mutual bitterness and resentment that accompanied this termination resulted in “a lapse of historical memory” and to Weadick's relative under-recognition by the organization for which he did so much. 相似文献

Pretto, F.A., Schultz, C.L., Langer, M.C. 4.02.2015. New dinosaur remains from the Late Triassic of southern Brazil (Candelária Sequence, Hyperodapedon Assemblage Zone). Alcheringa 39, xxx–xxx. ISSN 0311-5518The oldest unequivocal dinosaurian records come from Upper Triassic strata, mostly from Argentina and Brazil. Recent fieldwork in the Brazilian deposits of Ischigualastian age (late Carnian–earliest Norian) have resulted in the collection of a new specimen (UFRGS-PV-1240-T) identified as dinosaurian by the presence of a concave emargination on the ventral surface of the femoral head and a well-developed deltopectoral crest on the humerus, which extends for ca 40% of its estimated proximodistal length. Although fragmentary, the material increases the dinosaurian record from the Late Triassic of Brazil, which is still modest when compared with coeval Argentine strata. Additionally, UFRGS-PV-1240-T augments the dinosaurian diversity at the ‘Sítio Janner’ site, which was until now restricted to the sauropodomorph Pampadromaeus barberenai. The new specimen is larger than most early dinosaurians (except for herrerasaurids), implying that members of the group were already occupying niches otherwise explored by other larger-bodied taxa in the ‘Sítio Janner’ palaeofauna, and Late Triassic palaeoenvironments in general.Flávio A.

Archaeobotanical analysis of moat sediments from the Neolithic site of Chengtoushan, Hunan, China, provides evidence of the
land-use change for rice and foxtail millet cultivation around the site. Rice constantly appeared through the three phases
of Daxi culture with high percentages, while accompanying wetland species of paddy field weeds gradually decreased. In contrast,
foxtail millet increased together with upland field and ruderal weeds through the time. These changes suggest that foxtail
millet cultivation was established with the expansion of dry farming in region of the site, while rice cultivation was continuously
practiced on the alluvial plain surrounding the site. This diversification of land-use through the addition of foxtail millet
cultivation may be attributed to population increase or as a buffer to natural disasters such as flooding. In addition, gathering
of wild nuts and fruits continued alongside cultivation. These multiple strategies for food procurement provided sustainable
food supply for the population of Chengtoushan for 1,800 years. 相似文献
