Trees as technology: planting shelterbelts on the Great Plains

The turbulent climate of the Great Plains made windbreaks necessary for the protection of settlers and their livestock and crops. At first individual farmers tried to plant their own shelterbelts but with little success. The US Forest Service, with the establishment of the Bessey tree nursery, in 1902, and the field planting of the Nebraska National Forest, developed the expertise to carry out farm forestry on the plains. In 1934 the Forest Service undertook the Prairie States Forestry Project, an eight‐year program to plant shelterbelts from Canada to Texas, in response to the Dust Bowl and the Great Depression. These shelterbelts were a technological solution to environmental and social problems. As they grew, successful shelterbelts developed forest characteristics and served as habitat for birds and wildlife. As systems that were both technical and ecological, shelterbelts embodied a confluence of culture and nature in the technology that farmers and foresters used to engineer a more suitable environment for American society on the Plains.     

Six seasons of wild pea harvest in Israel: bearing on Near Eastern plant domestication

Harvest experiments of wild crop relatives are essential for our understanding of the biology of wild plants embodied in the economy of ancient forager communities. Most of the previous experimental harvest reports spanned a single season and therefore are unable to address questions concerning long-term yield potential. Herein we report on six consecutive harvest seasons taking place at four sites in Israel that harbour wild pea populations: three typical Pisum fulvum sites and one typical Pisum elatius site. Three out of the four sites showed no indication of a decline in grain yield as a result of repeated harvest and the removal of a considerable portion of mature seeds. Site-specific factors seem to have a strong influence on the grain yield as no seasonal yield similarity was observed between adjacent and ecologically similar sites harbouring the same wild pea taxon. The erratic year-to-year wild pea yield we observed calls for a reassessment of the presumed role of grain legume species in Near Eastern hunter–gatherers' diet. Combined with published data on cultivation of wild pea, our results are inconsistent with models suggesting protracted domestication of Near Eastern grain legumes or with the preliminary attempts to apply Niche Construction Theory to the study of plant domestication in the Near East.     

Unpacking the discursive Irish woman immigrant in eighteenth- and nineteenth-century Newfoundland

From the late 1600s to the early 1800s, Irish migrants journeyed to Newfoundland to take advantage of opportunities in the lucrative Newfoundland cod fishery. Focusing on the eighteenth and nineteenth centuries, this essay explores constructions of Irish-Newfoundland womanhood as articulated by local British officials, the Catholic Church, and male-centred family history narratives. These discourses located women at the margins of early settlement experiences or rendered them invisible altogether. Yet Irish-Newfoundland women were able to negotiate their own subjectivities within this discursive terrain, finding spaces for identity construction in the disjuncture between rhetoric and lived experiences. Some resided more immediately under the hegemonic gaze and struggled to break free from dominant narratives. But most became essential workers in household fishing production outside the capital of St John's, and their vital contribution as shore crews gave them considerable power and authority both in their households and in the broader community. Performing demanding physical work on stages and flakes (elevated wooden structures) or in gardens and fields, carrying out various economic activities in their own right, they were hardly the unproductive, unruly bodies of British official discourse or the passive flowers of civilisation narrated from Catholic pulpits. And far from being absent from the migration story, they were central players in community formation and the economic life of the island. In this historical context, proximity to/distance from hegemonic knowledge production created variations in identity construction within a group often represented in the literature as homogeneous and powerless.     

Legalism as an Executive Ideology: Foundations of Barack Obama's Leadership Style

Abstract

The purpose of this commentary is to explore the sources of decision-making by President Obama. Specifically, the article notes his strong foundation in legal education, law journal editing, and early occupational activities related to law practice. It is observed that a legalist cast of mind rather than broad statements about race, class, and nation define the Obama early period in office. These considerations are often at the center of presidential options chosen, especially in areas of foreign policy and global challenges. The article claims that “legalism” serves to place serious limits on initiatives and independent actions, but also serves to put a brake on tendencies to impose a new imperial presidency. Such ideological checks and balances show unique dimensions to this president, but also continuity with past limits to extremism.     

Fragments of Boats from the Canale Anfora of Aquileia,Italy, and Comparison of Sewn‐Plank Ships in the Roman Era

Fragments of Roman sewn‐plank boats have been found, during rescue excavations, in the Canale Anfora, an artificial channel used by Roman ships to enter the Roman city of Aquileia. Remains were found in both 1988 and 2005 at the same site. Elements of what were probably two boats are analysed and compared to other finds of Roman sewn boats found along the coast of the Veneto and Friuli Venezia Giulia regions. They are evidence of the use of this technique, instead of the more widespread mortise‐and‐tenon system, in the quite limited area of the Northern Adriatic. These boats were used both for inland and for maritime navigation.     

Implementation of Sustainable Urban Drainage Systems to Preserve Cultural Heritage — Pilot Motte Montferland

The shallow subsurface in historic cities often contains extensive archaeological remains, also known as cultural deposits. Preservation conditions for naturally degradable archaeological remains are strongly dependent on the presence or absence of groundwater. One of the main goals at such heritage sites is to establish a stable hydrological environment. Green infrastructural solutions such as Sustainable Urban Drainage Systems (SUDS) can support preservation of cultural deposits. Several cases show that implementation of SUDS can be cost effective at preservation of cultural deposits. These include Motte of Montferland, City mound of Vlaardingen, Weiwerd in Delfzijl, and the Leidse Rijn area. In all cases, the amount of underground infrastructure is minimised to prevent damaging cultural layers. SUDS have been implemented to preserve cultural heritage. The first monitoring results and evaluation of the processes give valuable lessons learned, transnational knowledge exchange is an important element to bring the experiences across boundaries.     

分裂与延续:六朝士族文化与中华文明传承

In the Six dynasties, the clans of the scholar-official stratum not only occupied a dominant place in social and cultural life but also played an important role in maintaining Chinese civilization. As a succession of northern minorities entered the Central Plains, foreign culture became widespread and the Chinese people and culture experienced an unprecedented crisis. Thanks to the scholar-official clans who shouldered the burden of preserving Chinese culture, Chinese civilization was able to persist through the ages to become an “unbroken” civilization. These clans can be categorized in three groups according to their territorial origin: “Clans of the Wu Area” which developed in Jiangnan after the Han dynasty; “Immigrant Clans” which moved to Jiangnan from the north during the Jin dynasty and the ensuing dynasties, these being referred to jointly as “the Southern Clans”; and “the Northern Clans,” being those clans that remained in their homelands (Shandong and the Central Shaanxi Plain) during the period of ethno-national amalgamation in the north of China. Though these clans had various cultural characteristics due to different historical roots, cultural traditions and ancestry, their clan learning had a common core, i.e., the study and practice of Confucian rites as established in the Han dynasty. This formed the basis for the integration of Han with other cultures, making a sound foundation for the further development of the Chinese civilization.
