ABSTRACT

We integrate functional weed ecology with crop stable carbon and nitrogen isotope analysis to assess their combined potential for inferring arable land management practices in (semi-)arid regions from archaeobotanical assemblages. Weed and GIS survey of 60 cereal and pulse fields in Morocco are combined with crop sampling for stable isotope analysis to frame assessment of agricultural labour intensity in terms of manuring, irrigation, tillage and hand-weeding. Under low management intensity weed variation primarily reflects geographical differences, whereas under high management intensity fields in disparate regions have similar weed flora. Manured and irrigated oasis barley fields are clearly discriminated from less intensively manured rain-fed barley terraces in southern Morocco; when fields in northern and southern Morocco are considered together, climatic differences are superimposed on the agronomic intensity gradient. Barley δ13C and δ15N values clearly distinguish among the Moroccan regimes. An integrated approach combines crop isotope values with weed ecological discrimination of low- and high-intensity regimes across multiple studies (in southern Morocco and southern Europe). Analysis of archaeobotanical samples from EBA Tell Brak, Syria suggests that this early city was sustained through extensive (low-intensity, large-scale) cereal farming.  相似文献

This article investigates the determinants of political cleavages composing the structure of political attitudes in Jordan, Tunisia, and Yemen following the Arab Spring. Further, it tests whether political cleavages carry predictive weight on ordinary citizens’ electoral choices in general elections. Using the Sixth Wave of the World Values Survey, discriminant analysis was conducted to generate the dimensionality, type, and structure of political attitudes in the three nations. Findings suggest that the structure of political attitudes in Jordan, Tunisia, and Yemen is multidimensional: the Islamic‐Secular division, a conflict along economic policy visions and an emerging divisive dimension concerning political reform. Evidence indicates that political cleavages do not possess significant predictive power in determining voters’ choice at elections booths. This research also points to the significance of social transformation processes such as modernization and globalization in causing a shift in values among ordinary citizens in the Arab World. This research argues that in countries where the effects of modernization and globalization are higher, a weakening of the Islamic‐Secular division is witnessed. This research is important since it paves the way for further empirical analysis on political ideology in the Middle East. It shatters conjectures concluding that Arab polities are only divided by a single hierarchical dimension: Islamic‐Secular. It contributes to comparative research on the dimensionality of political ideology by showing that the Arab World is similar to the industrialized world in the dimensionality, nature, and structuration of political ideology.  相似文献

To fully appreciate Walker Connor's contribution to the foundation of the contemporary study of nationalism, two main factors must be taken into account. First, the context of positivist behavioural political science within which in the late 1960s and throughout the 1970s, he articulated his critique of the concept of nation‐building. In this context, Connor emerged as a critic of the limitations and the naivité of positivist modernization theory. His dissenting voice called for critical rethinking and revision of the central concepts of the theory of political development, some of which enjoyed almost doctrinal status. Second, despite his criticism of modernization theory, Connor retained a strong conviction that nations and national sentiment were the products of modernity; indeed, in his judgement, they formed the primary content of modernity. This too was a critical stance within the rising tide of nationalism studies since 1989–1990, when ideology and wishful thinking influenced to a considerable extent the interpretation of nationalism. Walker Connor's intellectual legacy should thus be understood as a heritage of critical thought that is informed by a noteworthy awareness of the moral responsibilities of scholarly analysis.  相似文献

Current issues in Chinese Neolithic archaeology   总被引:7,自引:0,他引:7  
Every year archaeologists in China discover numerous rich sites demonstrating significant regional variability in Neolithic cultures, primarily from about 6500 B.C. to 1900 B.C. This paper discusses a topic not covered in detail in current or forthcoming publications, the origins and development of agricultural systems. Recent fieldwork in both northern and southern China suggests that initial steps toward settled agricultural villages began circa 11,000 B.P. I review evidence for the cultivation of millet, rice, and other plants as well as animal husbandry in different regions of China. There are several later Neolithic sites in northern China with evidence for rice cultivation. I suggest how future research projects can investigate regional variation and change over time in subsistence and settlement during the Neolithic Period.  相似文献

Hunter-gatherers in eastern North America utilized gourds at least 7000 years ago, operating at the early end of a sequence that ended with maize-based agriculture across most of the area. Various subregions differed from each other in timing and degree of participation in premaize crop production. A Midwestern record of native seed plant domestication preceding the adoption of maize is documented, and the significance of this phenomenon is now recognized. Recent archaeobotanical information highlights the amount of geographic variability, limiting the utility of earlier broad-scale interpretations. This paper includes a comparison of sequences in selected subregions: the Midwest/Midsouth, the Southeast, the Lower Mississippi Valley, the Trans-Mississippi South, and the Northeast.  相似文献

Chinese historiography of modern China in the 1980s and 1990s underwent a paradigmatic transition: in place of the traditional revolutionary historiography that bases its analyses on Marxist methodologies and highlights rebellions and revolutions as the overarching themes in modern Chinese history, the emerging modernization paradigm builds its conceptual framework on borrowed modernization theory and foregrounds top‐down, incremental reforms as the main force propelling China's evolution to modernity. This article scrutinizes the origins of the new paradigm in the context of a burgeoning modernization discourse in reform‐era China. It further examines the fundamental divides between the two types of historiography in their respective constructions of master narratives and their different approaches to representing historical events in modern China. Behind the prevalence of the modernization paradigm in Chinese historiography is Chinese historians' unchanged commitment to serving present political needs by interpreting the past.  相似文献

关于民国乡村建设运动的几个问题   总被引:1,自引:0,他引:1  
上世纪二三十年代兴起的乡村建设运动是一场社会改良运动,即在维护现存社会制度和秩序的前提下,采用和平的方法,通过兴办教育、改良农业、流通金融、提倡合作、公共卫生和移风易俗等措施,以复兴日趋衰落的农村经济,实现所谓“民族再造”或“民族自救”。这种改良性质并不意味着乡村建设运动就无意义可言,首先,乡村建设运动的兴办教育、改良农业、流通金融、提倡合作、公共卫生和移风易俗等内容,对于解决农民尤其是自耕农的生产生活困难、推动社会进步起过一定的积极作用;其次,一些实验区在兴办教育、改良农业、流通金融、提倡合作、公共卫生和移风易俗的过程中所创造出的一些经验和方法,对于今天相关的农村工作有其借鉴的意义;第三、当时有成百上千的知识分子抛弃城市的优厚待遇和舒适的生活环境,“深入民间”,把他们所学到的知识文化和科学技术传授给农民,帮助他们扫除文盲和脱贫致富。对此,应予充分肯定。  相似文献
