The United States Department of Agriculture Forest Service traditionally has been dominated by white, male for esters, particularly in its professional and leadership ranks. Beginning in the mid-1970s, however, civil rights legislation, lawsuits, and statutes that mandated interdisciplinary planning collectively impelled the agency to begin diversifying by race, gender, and profession. This study attempts to quantify the progress the agency has made in workforce diversification since the early 1980s by grouping Forest Service job series into categories and tracking changes in these categories over time. The study reveals that the numbers of employees in “nontraditional” Forest Service fields (e.g., the social and biological sciences) increased markedly, but that these employees remain vastly outnumbered by employees in traditional fields such as forestry. The number of women in the agency also increased greatly, but women made much greater gains in administrative support positions than in jobs that put them in the pipeline for leadership positions. They remain vastly overrepresented in clerical and administrative positions and highly under rep resented in professional and technical positions. People of color made gains in nearly all job categories, but, like women, remain significantly overrepresented in jobs that will not lead to leadership positions. Thus, while aggregate numbers show greater diversity in the Forest Service workforce, a more detailed analysis reveals that the leadership ranks are still the domain of white, male foresters.  相似文献

Current views of Cyprus during the Middle Bronze Age (or Middle Cypriot period) depict an island largely isolated from the wider eastern Mediterranean world and comprised largely if not exclusively of “egalitarian,” agropastoral communities. In this respect, its economy stands at odds with those of polities in other, nearby regions such as the Levant, or Crete in the Aegean. The publication of new excavations and new readings of legacy data necessitate modification of earlier views about Cyprus’s political economy during the Middle Bronze Age, prompting this review. We discuss at some length the island’s settlement and mortuary records, materials related to internal production, external exchange and connectivities, and the earliest of the much discussed but still enigmatic fortifications. We suggest that Middle Bronze Age communities are likely to have been significantly more complex, mobile, and interconnected than once envisaged and that the changes that mark the closing years of this period and the transition to the internationalism of Late Bronze Age Cyprus represent the culmination of an evolving series of internal developments and external interactions.

This paper summarizes phytolith analyses from four pre-Columbian agricultural raised-field sites of the coastal savannahs of French Guiana—Savane Grand Macoua, Piliwa, Bois Diable and K-VIII—and carbon isotope analyses from the first-named site. The combined phytolith and 13C isotope analyses evidence the transformation of the landscape from a relatively homogeneous wetland vegetation comprised of a mixture of C4 and C3 plants (the latter including Cyperaceae and other herbaceous monocots such as Marantaceae and Heliconia, Oryzoideae grasses, and other plants typical of frequently flooded areas) to the construction of raised fields that were dominated by C4 plants (maize and other Panicoideae grasses). Our analysis proves the utility of phytoliths for tracing the agricultural history of landscapes, showing that, as in other parts of the Central and South American lowlands, maize (Zea mays) was one important crop cultivated in raised fields. We also estimated the productivity of raised-field agriculture, showing that in combination with other subsistence activities, it certainly had the capacity to sustain sizeable populations.  相似文献

A pile-dwelling settlement, dated to the final Bronze–early Iron Age (XII–XI century BC), was excavated at Stagno, near Leghorn (Tuscany, Italy). The site presented a well-preserved portion of the wooden foundation structure buried by sediments rich in plant remains: both wood and plant remains were subjected to archaeobotanical investigation. The ultimate goal was to improve our knowledge on agricultural economy and wood usage in Tuscany during the prehistoric ages. The results pointed to a farming system based on Triticum spp. (wheat), Hordeum spp. (barley) and Leguminosae cultivation in addition to the gathering of wild fruits, such as Corylus avellana, Cornus mas, Prunus spp., Vitis spp. Many of these plant remains are associated to a wetland context. Mesohygrophilous trees, such as deciduous Quercus, Ulmus minor, Fraxinus cf. excelsior, and Sorbus were used for the construction of the pile-dwelling structures; the choice of these plants indicates a good knowledge of the technological characteristics of timber.  相似文献
