Through ethnographic and historical analysis of the Negev region of Israel, this article examines competitive planting as a common tool in land conflicts. In a context of disputed land ownership, some Bedouin Arab residents plant crops in defiance of government policy. Government enforcers of land‐use regulations destroy many of these crops and engage in counterinsurgent tree‐planting. I suggest that planting is such a potent tactic because it draws on “environmental idioms” of agricultural labor, the rootedness of trees, and a fundamental Jewish‐Arab opposition that have been central to the development of both Israeli and Palestinian nationalisms. For Bedouin Arabs, whose relationship to both nationalisms has long been contested, the multivalent symbolism of planting makes it a particularly promising tactic for asserting land claims. Further, I contend that these plantings demonstrate both the power of environmental idioms to structure land claims along ethnic lines and the creative potential of participants to challenge dominant environmental discourses by adding new connotations. 相似文献

Soil was modelled with linearly elastic three-dimensional finite elements. Lateral spring stiffness was calculated from FE results. Spring stiffness is shown varying linearly with shaft diameter. It is also found that spring stiffness is inversely proportional to powers (less than unity) of pile flexural rigidity. Scaling factors for shaft diameter and pile flexural rigidity are introduced. Basic stiffness of lateral spring is studied considering both full vertical slippage and zero slippage between the soil and the pile. Relevant relationships for stiffness are proposed. Some applications are suggested. 相似文献

This paper considers the epistemic career of visual media in ethology in the mid-20th century. Above all, ethologists claimed close contact with research animals and drew scientific evidence from these human-animal communities, particularly in public relations. However, if we look into the toolboxes of comparative behavioral biologists, it becomes evident that scientifically valid research results were primarily obtained by experimenting with model images. These visual specimens tell a technical story of the methodological requirements in behavioral science necessary to bridge everyday observations between the laboratory and the field. By neutralizing individual traces of animal bodies as well as their observers, they prompted the abstraction of ethological hypotheses. The case study of East-German biologist Günter Tembrock (1918–2011), who maintained his own collection of newspaper clippings, drawings, photographs, and films, offers a new perspective on the methodological development of this field. Furthermore, this article contributes to a scholarly discussion geared toward expanding the spaces of ethological research. My analysis of the image collections of the Forschungsstätte für Tierpsychologie presents the archive as a relevant site of study in the history of ethology. 相似文献

Ongoing excavations at Tell Abraq (Emirate of Umm al-Quwain, U.A.E.) are revealing new aspects of this multiperiod site, which was occupied from c. 2500 BC to 300 AD. Together with substantial architecture dated to the 2nd and 1st millennia BC, relevant assemblages of archaeological materials are being collected and dated to different phases of the site’s life. Among this material, exceptional is the discovery of two jars bearing the impression of two different cylinder seals, which will be presented here. Seal impressions on any media are extremely rare in the whole of south-eastern Arabia and strongly indicate a foreign provenance for the jars. Their iconographic study, the fabric and morphological parallels for the jars, and probable chronology will be discussed, as this can highlight transmarine connections during the late 2nd-first half of the 1st millennium BC, as well as provide new data to address chronological issues in south-eastern Iran itself. 相似文献

Soft‐stone vessels are a prominent feature of ancient culture throughout south‐east Arabia and the Gulf. Chlorite and steatite occur naturally in the al‐Hajar Mountains of the United Arab Emirates (UAE) and Oman; but until now, apart from the discovery of a few unfinished pieces, ancient production of soft‐stone vessels had yet to be documented in Arabia. This paper reports the discovery and preliminary analysis of soft‐stone vessel production at the site of Aqir al‐Shamoos. At this small and secluded mountain village, a range of soft‐stone vessels that are well known in the south‐east Arabian Iron Age were produced on a scale far beyond what was needed for local consumption. 相似文献
