This article examines the portrayal of non-North Koreans in North Korean textbooks to assess the influences on the formation of North Korean identity, and how such identity formation is important in Kim Jeong-il's retention of power. This study not only looks closely at textual representations; it also examines how political and ideological changes in North Korea had a critical influence on these texts. The study encompasses both lexico-grammatical analysis and the analysis of textual and visual images, based on an examination of six North Korean language textbooks published from 1954 to 2000. It demonstrates that North Korean identity is defined through the portrayal of non-North Koreans, particularly enemy others. The portrayal of non-North Koreans facilitates the formation of a solid North Korean identity – an identity that entails serving their political leaders, remaining vigilant against threats to their country, and liberating South Koreans from poverty and oppression by America and its puppet states.  相似文献

In the investigation of the dispersal of maize (Zea mays ssp. mays) from south-central Mexico to the northern and southern limits of agriculture in the Western Hemisphere archaeologists and paleoethnobotanists are increasingly turning to the microbotanical record. Recent analysis of phytolith assemblages from charred cooking residues on pottery sherds in central New York recovered using 209 rondel phytolith variables has identified maize as early as 2270 ± 35 B.P. In this article we use discriminant analysis to re-classify these rondel phytolith assemblages resulting in only seven variables. The results are consistent with those achieved earlier using many more variables and a less formal statistical approach in terms of classification and in similarity of the original and reduced data matrix as seen by the Mantel test and cluster analyses.  相似文献

The initial Late Paleolithic, said to appear between 40 and 30 kya in eastern Asia, is defined by the appearance of many innovations. These archaeological indicators include the appearance of more refined stone tool making techniques (e.g., include the appearance of blade and microblade technology), complex hearth construction, use of pigments and personal ornamentation, as well as worked faunal implements such as bone and antler tools. We report here new findings from a multidisciplinary research project conducted at the Shuidonggou (Choei-tong-keou) site complex in northern China, a series of localities that date from the initial Late Paleolithic to the Neolithic.  相似文献

20世纪60年代中期,为摆脱传统殖民主义和南部非洲种族主义的束缚,坦桑尼亚和赞比亚两国提出了修建铁路的计划,并得到中国政府的支持和大力援助。当时,中美处于冷战对抗最为尖锐的时期,美国担心中国借援建铁路获得政治利益,担心中国借机向非洲输出革命,更担心共产主义在非洲扩大影响。为此,美国政府先后使用"拖延"和以大北公路"替代"坦赞铁路的策略,企图阻止中国援建坦赞铁路,以实现将中国阻隔于南部非洲之外的目的。  相似文献

山东青州邢氏原是务农的家族,在邢玠科举成功为官之后,转型为官宦之家,成为地方望族。从万历时的邢玠开始,到崇祯时的邢彤庭,邢氏从事宗族建设,制定并实践各种宗族制度,宗族乡约化、组织化。邢氏受到宋代程颐、程灏的宗会思想很大影响,通过"宗会"复兴"宗法"。这是宋以后宗族组织化的一种重要模式,以往的宗族研究重视不够。邢氏也编修了族谱,有家庙或者家堂,将御赐的祭田作为族田,还设置了宗学、义仓,族长实际上就是宗正。邢玠受到苏洵苏氏谱法以及睦族主张的影响较大,邢氏族谱着眼于睦族,收录大量宗族制度的文献,内容非常丰富,面貌大为改观,成为重要的民间文献。晚明不仅再造宗族,也再造了族谱,完成了中国近世宗族与族谱的基本形式。  相似文献

Situated along the southern fringe of the North Sea basin, northwest Belgium holds great potential for understanding hunter–gatherer responses to environmental change at the Pleistocene–Holocene transition. Recent intensive fieldwork has yielded valuable data on the palaeoenvironment, chronology, and hunter–gatherer mobility and land use in this region. At the Late Glacial/Early Holocene transition this region was comprised of a landscape of coversand ridges and lakes that flanked the northern part of the Scheldt river basin. This landscape was highly productive for hunter–gatherer populations. As the landscape developed in response to the increasing water table caused by the inundation of the North Sea populations responded by changing their forms of mobility and land use. These changes are indicated by the reduction in the number and density of sites, as well as their geographical settings, from the Late Glacial (Federmesser) and Early Mesolithic to the Middle-Final Mesolithic. Late Glacial/Early Mesolithic sites indicate much higher mobility comprised of rapid displacements of camps and re-occupation of the same coversand ridges over long time-spans. Middle/Late Mesolithic sites indicate a reduction in mobility, increasing focus on prolonged riverside settlement, and a more rigid organization of residential sites.  相似文献

Distance and direction to source data were compiled on the main toolstones employed at 83 Paleoindian sites with concave-based points (ca. 11,000–10,000 B.P.) from across the recently deglaciated Great Lake-Northeastern area of North America. These data were used in order to more rigorously evaluate several much debated ideas about annual range mobility scale and land use patterns and how they changed over time as these groups colonized and settled into the area. Movements are significantly biased to north–south axes, strongly suggesting these represent mainly seasonal moves and procurement of toolstones during regular travels rather than by specialized task groups. Means of comparing the scale of range mobility to ethnographic norms are explored and the results clearly show that these groups, especially the earliest occupants, had large annual range mobility scales and distinctive patterns of land use that are rarely seen or approached historically. They had to have been intensively targeting widely spaced but relatively abundant resources on the landscape. The only ethnographic groups who come close to such patterns historically were all caribou hunters, a perspective consistent with the idea these groups regularly exploited that resource. As long suggested, these land use patterns are probably related to the colonization of new lands in which there were little or no existing populations.  相似文献

Central western Argentina is the southern boundary of prehispanic maize in the archaeological record. This paper explores the stable isotope information from human bone (δ13C, from collagen and δ13C from apatite) and tooth (δ13C from enamel) samples in order to characterize the temporal and spatial trends of these isotopes and to understand them in terms of human diet. We analyzed 104 human individuals from the last 6000 years. Using the Kellner and Schoeninger (2007) model the results shows a high variation in human diet with few human individuals with a notably high significance of C4 plants (probably maize) as an energy source and these samples have a chronology around ca. 1000 years BP. On the other hand a high variation in an individual’s dietary life history is shown by differences between δ13C collagen, apatite and enamel.  相似文献

2011年3~4月,安徽省文物考古研究所对安徽泗县刘圩遗址进行了抢救性发掘,揭示一批汉至唐宋遗迹。其中,唐宋汴河北堤的发现,在隋唐大运河泗县段尚属首次;宋代踩踏面及相关遗迹的发现反映了汴河漕运的繁华;北宋末至南宋初土坑墓的发现印证了相关文献记载的汴河废弃时代。  相似文献
