Foraging Decision

AbstractSignaling theory has much to offer anthropology and archaeology, which is in part why there is an increasing number of applications and healthy debates surrounding how best to apply it. One of those debates surrounds whether big game hunting is a costly signal or simply an aspect of efficient foraging. Grimstead (2010) contributed to this debate by showing that long-distance big-game hunting (greater than 100 km roundtrip) produces higher caloric return rates than does local small-game hunting, despite increased costs of travel and transport for the former. Whittaker and Carpenter (this issue) present a model that also suggests long-distance big-game hunting produces higher economic returns than local foraging but only up to about 50 km. This paper provides further details on the tenets of the Grimstead (2010) paper in response to criticisms by Whittaker and Carpenter (this issue), and then uses a previously published central place foraging model (Cannon 2003) to show that another model also shows long-distance big-game hunting over a distance greater than 100 kilometers roundtrip produces higher returns than local foraging.

Park Service

A significant role of the National Park Service in the United States is the preservation of pristine landscapes. The natural landscape offers the visitor the opportunity to enjoy the wonders of nature and its processes to create beautiful vistas, soaring mountains, and the interplay of vegetation communities. The visitor to the park can be a passive recreationist and observe the landscape or be an active recreationist and experience the landscape through hiking, biking, mountain climbing and a range of other activities. The key linkage between the active and passive recreationist is the landscape that they are experiencing, in one perspective or the other. Any disruption of that natural landscape diminishes the experience. Unfortunately, the perception of the disruption varies with each individual. The trail to get to a scenic vista can be overlooked by some observers, while others believe it is an example of the devastation of human impact.

AbstractThis paper argues that abductive reasoning has a central place in theorizing Health Professions Education. At the root of abduction lies a fundamental debate: How do we connect practice, which is always singular and unique, with theory, which describes the world in terms of rules, generalizations, and universals? While abduction was initially seen as the ‘poor cousin’ of deduction and induction, ultimately it has something important to tell us about the role of imagination and humility in theorizing Health Professions Education. It is that which makes theory possible, because it allows us to ask what might be the case and calls attention to the role of creative leaps in theory. Becoming aware of the abductive reasoning we already perform in our research allows us to take the role of imagination—something rarely associated with theory—seriously.

Abstract Millions of wetland basins, embedded in croplands and grasslands, are biodiversity hotspots in North America’s Prairie Pothole Region, but prairie wetlands continue to be degraded and drained, primarily for agricultural activities. Aerial insectivorous swallows are known to forage over water, but it is unclear whether swallows exhibit greater selection for wetlands relative to other habitats in croplands and grasslands. Central-place foraging theory suggests that habitat selectivity should increase with traveling distance from a central place, such that foragers compensate for traveling costs by selecting more profitable foraging habitat. Using global positioning system (GPS) tags, we evaluated habitat selection by female Tree Swallows (Tachycineta bicolor) at 4 sites containing wetlands and where terrestrial land cover was dominated by grasslands (grass, herbaceous cover) and/or cultivated cropland. We also used sweep-net transects to assess the abundance and biomass of flying insects in different habitats available to swallows (wetland pond margins, grassy field margins, and representative uplands). As expected for a central-place forager, GPS-tagged swallows selected more for wetland ponds (disproportionate to availability), and appeared to increasingly select for wetlands with increasing distance from their nests. On cropland-dominated sites, insect abundance and biomass tended to be higher in pond margins or grassy field margins compared to cropped uplands, while abundance and biomass were more uniform among sampled habitats at sites dominated by grass and herbaceous cover. Swallow habitat selection was not clearly explained by the distribution of sampled insects among habitats; however, traditional terrestrial sampling methods may not adequately reflect prey distribution and availability to aerially foraging swallows. Overall, our results underscore the importance of protecting and enhancing prairie wetlands and other non-crop habitats in agricultural landscapes, given their disproportionate use and capacity to support breeding swallow and insect populations.

В статье рассматриваются советские и постсоветские традиции празднования Дня Победы, анализируется его роль в современном социокультурном пространстве России. Источниками для работы послужили материалы по Омскому региону - результаты опросов и личных наблюдений автора, данные средств массовой информации и официальных источников. Делается вывод о центральном месте Дня Победы в современном праздничном календаре и его важной роли в объединении российской нации на основе мемориализации общего исторического прошлого. Автор объясняет значимость праздника для населения страны сохранением традиционных ценностей и смыслов, а региональные особенности празднования и процессов коммеморации - различными факторами исторического, экономического, политического, социокультурного порядка. Празднование 70-летнего и 75-летнего юбилеев Победы отразило позитивное изменение общественного сознания в постсоветской России, что проявилось в увеличении интереса к историческому наследию, усилении чувства благодарности ветеранам и гордости за их подвиг, осознании причастности каждого к историческим событиям славного прошлого страны. День Победы, выполняя главные функции праздника, поддерживает преемственность традиций, объединяет различные социальные группы, воспитывает уважение к историко-культурному наследию и патриотизм. This article examines the Soviet and post-Soviet tradition of Victory Day celebrations and analyzes their role in modern Russian socio-cultural space. It is based on materials from the Omsk Region, including the results of surveys, data from the mass media and official sources, as well as the author’s personal observations. The author describes the central place of Victory Day in the modern holiday calendar and its important role in uniting the Russian nation by memorializing a common historical past. The author considers the role of the holiday in preserving traditional values and meanings, and describes the regional features of the celebration and the processes of commemoration as shaped by various historical, economic, political, and socio-cultural factors. The celebration of the 70 th and 75 th post-Soviet anniversaries of the victory reflected a positive change in public consciousness that was manifested in greater interest in the historical heritage, an increased sense of gratitude toward veterans and pride in their accomplishment, and an awareness of everyone’s involvement in the historical events of the country’s glorious past. Victory Day, performing the main functions of a holiday, supports the continuity of tradition, unites various social groups, and promotes patriotism and respect for the historical and cultural heritage
