The processes that led to the transition from small mobile groups of hunter-gatherers in the Late Pleistocene to sedentary communities of the Early Holocene in north China are poorly understood. The Donghulin site in Beijing was occupied at the onset of the Holocene, and excavations have revealed a rich archaeological record for investigating the changing subsistence strategies during this transitional period. A functional study of two grinding stones (a slab and a handstone) near a burial dated to 9220–8750 cal BC at Donghulin investigated the range of plants exploited during this early occupation period. Starch residues indicate that the grinding stones were used for processing plants, and confirm processing of acorns, which is consistent with the incidence of oak in the pollen record. The usewear, with only rare patches of developed polish, suggests that plant parts of low silica content were processed, although usewear on the handstone suggests processing of two or more plant taxa. The results suggest that the use of grinding stones to process plant foodstuffs, particularly acorns, may have played a major role in the subsistence strategy during the transitional period to sedentism and agriculture in some parts of north China. 相似文献

This article uses a single, critical case to assess the plausibility of hypotheses that emerge from the literature on civic environmentalism. In particular, scholars have argued that local, collaborative environmental decision making is likely to yield solutions that are both more durable and environmentally superior to those generated by more conventional policymahing processes. The analysis suggests, however, that such outcomes are unlikely in the absence of stringent regulatory requirements established at the federal or state level. This is because local officials face fiscal constraints that exacerbate the already substantial disparity in political resources between citizens and development interests. 相似文献

ABSTRACTPolynesian Rotuma was blessed by its large coconuts and became an early focus for foreigners seeking trade in coconut oil and copra. Once the island became part of British Fiji in 1881, Rotumans voiced their concerns about increased shipping costs when going via Fiji as the port of entry. From the early 20th century they had visions of owning their own ship and thus greater control over prices for exported copra and imported goods. This article seeks to examine their constant efforts to make traders deal more fairly while seeking to manage their own shipping. Though they had some success, particularly when they formed a cooperative after World War Two, their goal largely proved unattainable but the vision and the voices have endured. 相似文献

ABSTRACTFor more than two decades, theories on regional clusters have inspired economic and structural policies at the European, national and regional levels. Based on the assumption that clusters generate innovation, policy-makers at all levels of governance have adopted instruments and mechanisms to stimulate, resource and sustain clusters. Despite the considerable attention paid to the clustering phenomenon, empirical evidence on to what extent firms’ innovation activities benefit from operating in clusters is scarce and inconclusive. This paper contributes to the micro-foundation of clustering effects by examining the characteristics and activities of cluster firms in relation to their innovativeness. Bridging innovation, management and cluster theories, it is argued that structural and relational embeddedness, relational capital and absorptive capacity influence clustered firms' innovativeness. Partial least-squares structural equation modelling of data from 104 firms in two software and information technology service sector clusters reveals that firms’ structural embeddedness (i.e. frequency of interactions) in clusters and external networks facilitates innovation cooperation. Firms’ absorptive capacity reinforces this positive effect of cluster-internal interactions on innovation cooperation. Results also suggest a substitution effect of trust as relational control mechanisms for formal control mechanisms within the cluster. However, the study finds no significant impact of firms’ innovation cooperation within the cluster (i.e. relational embeddedness) on their innovation success. 相似文献

AbstractThis article aims at distinguishing recurrent population movements within the territory of the Russian Federation between urban localities of different sizes and rural areas in connection to the processes of urbanization, suburbanization, and de-urbanization. Incomplete urbanization and the strong polarization of socio-economic space in Russia have resulted in two powerful contradictory population flows: centrifugal seasonal sub- and de-urbanization and centripetal labor migration from rural and small towns to large urban centers. The article discusses three forms of recurrent population mobility in Russia: (1) daily commuting of urban and rural inhabitants within metropolitan areas; (2) commuting to large cities and their suburbs for long-term employment intervals (weekly, monthly, etc.), (3) second-home commuting to countryside dachas. Unfinished urbanization in Russia not only attracts rural and small towns’ population to major cities but also keeps it within the latter. It slows down the real de-urbanization and induces specific dachas (second-home) suburbanization/de-urbanization, with these processes being closely interrelated. An opportunity to earn money in cities together with the impossibility of moving to major centers due to expensive housing encourages households to remain in small towns and rural areas. Meanwhile, inhabited rural localities (even ones distant from cities) attract seasonal population (dachniks). 相似文献
