COVID-19 has caused enormous economic and social disruptions that may have lasting effects on employment, income, and working conditions. Critically, these disruptions often have a negative impact on mental health. While significant research has examined the relationship between COVID-19 and mental health, most of these studies focus on urban centres. This paper presents results from a pilot study conducted in two rural counties in Ontario, Canada on the experiences of residents from small and rural communities related to COVID-19. Based on 3496 survey results, this study quantifies the negative impact of COVID-19 on overall mental health and the confounding role of gender, income, and age. Results must be used to expand the dialogue around rural mental health and to ensure appropriate programs and policies are developed. 相似文献

The Emerald site, also known as the Emerald Acropolis, was an early Mississippian pilgrimage center key to Cahokia’s development. This paper presents the hitherto unpublished results of two archaeological projects conducted at the site, one led by Howard Winters and Stuart Struever in 1961 and the other by Robert Hall in 1964. These investigations produced the most comprehensive information on Emerald’s Moorehead phase (1200–1300 CE) occupation, during which two of its mounds were capped, a secondary mound was constructed on the central mound, and a mound-top structure was erected on this secondary mound. Similar activities took place throughout the region during the thirteenth century, a time marked by dramatic social, political, and religious change in Greater Cahokia. Based on these data, we argue that people returned to Emerald to memorialize or draw on the powers inherent there and thus reincorporate this place into the newly imagined thirteenth century Cahokian world. 相似文献

Transitions from terminal Pleistocene Upper Paleolithic foraging to Holocene Neolithic farming and pastoralist economic orientations in the northern Tibetan Plateau are examined from the perspective of Epipaleolithic sites located near Qinghai Lake, Qinghai Province, western China. Jiangxigou 2 is an artifact-rich, multicomponent midden site with the main period of occupation dating ca. 9000–5000 cal yr BP, containing abundant flaked stone artifacts including a substantial proportion of microlithic tools, abundant faunal remains including gazelle, deer, and sheep, and a small number of ceramics, including the oldest known on the Tibetan Plateau. Heimahe 3, on the other hand, is a brief hunter's camp dating ca. 8450 cal yr BP, with evident affinities to late Upper Paleolithic camps in the same region that date several thousand years older. The two distinctively different sites are probably nodes within a single Epipaleolithic foraging system that developed on the margins of the high Tibetan Plateau during the early Holocene, and that served as a basis for colonization of the high-altitude Plateau at that time. Jiangxigou 2 appears to be connected to early Neolithic agricultural settlements along the upper Yellow River (Huang He) drainage during the middle Holocene, and may provide insights into forager–agriculturalist interactions that lead to the development of pastoralist systems in the region. 相似文献
