Gastrointestinal parasites in ancient South American camelid feces from the Atacama Desert (Pampa del Tamarugal,Tarapacá, northern Chile)

Faunal remains from archeological sites worldwide, especially feces and regurgitated pellets, are usually subjected to paleoparasitological examination, allowing the identification of past animal parasites. In this study, we analyzed 10 samples of South American camelid dung, which played an important role for the ancient human groups in the South-Central Andes, dated between 341 and 1635 calCE, from the Iluga Túmulos site (Pampa del Tamarugal, Tarapacá region, Atacama Desert, Chile). Microscopy examination revealed parasite remains in seven samples, in which oocysts of Eimeria macusaniensis and eggs of Lamanema chavezi/Nematodirus lamae, Trichuris sp., Moniezia sp., capillariids, strongylids, and unidentified nematodes were found. Although some of these species pose a potential health risk to camelids, most are not considered to be of major zoonotic importance, which could explain the absence of these parasites on human coprolites from this site analyzed previously. This first paleoparasitological study on camelid fecal remains from northern Chile sheds light on the occurrence of gastrointestinal parasites and its relationship with Andean ancient human populations and the environment.

明代年例银制度形成探论

明代年例银制度是经过长期演变逐渐形成的一项军事供给制度。宣德十年(1435)首先出现京运银,历经景泰、天顺时期,京运银两中有一笔银两开始向"岁例"发生制度性转变的趋势;成化、弘治之际,"常数"、"岁运"、"岁例"、"年例"、"年例银"等名称的出现是这笔京运银两制度化发展的结果,标志着明代年例银制度的初步形成;嘉靖十六年(1537)年例银一年一发的规定以及年例银会计预算制的出现,意味着明代年例银制度的完全确立。年例银制度的形成和确立,改变了明代国家的军事供给体制,是明代军事财政史上的一个重大变革。     

City branding in polycentric urban regions: identification,profiling and transformation in the Randstad and Rhine-Ruhr

In polycentric urban regions several distinct cities, none of which is dominant, cooperate and compete with each other to attract inhabitants and firms. In such settings city branding strategies do not solely affect one city, but the entire region. We examined how city branding in the face of ecological modernization, that is, delivering higher added economic value, while lowering environmental impacts, is playing out in the Dutch Randstad and the German Rhine-Ruhr. Our findings show that regional identity formation occurs at the sub-polycentric urban region level, coinciding more with (historical) economic profiles than with planning imaginaries. The Dutch cities profile themselves more along the lines of ecological modernization than their German counterparts. Differences between subregions within each polycentric urban region are also noticeable, where more industrialized regions, such as the Ruhr or southern Randstad focus on ‘green’, ‘liveable’ and ‘knowledge-oriented’, while cities with stronger knowledge-intensive sectors portray themselves as ‘smart’ or ‘sustainable’. Cities generally substantiate their profiles through projects, but a significant gap persists between reality and aspirations for improved environmental conditions. This is especially true for the Dutch cities, where many claims, but little visible action can be observed.     

清代垦殖政策与陕北长城外的生态环境

陕北长城外地区位于蒙陕农牧交错带,属于典型的脆弱生境地带。清代中央和地方两级政府针对当地汉民承租蒙民土地从事农牧业生产这一环节,在不同时期制定了不同的垦殖政策,经历了封禁、招垦、禁垦、拓垦四个阶段,这既是清政府对陕北长城外地区逐步认识和开发的过程,同时也是该地区生态环境变化的过程。在政策—人—环境相互作用的关系过程中,制度、政策与权力的结合对区域环境变化的影响具有根本性的驱动作用。     

Washing urban water: diplomacy in environmental art in the Bronx,New York City

Lillian Ball's art project WATERWASH creates a new ecological imaginary in the South Bronx. Building on a tradition of ‘maintenance art’, the work exhibits the power of soil, plants and microorganisms to clean water – in effect maintaining urban water. An overarching goal of WATERWASH is to educate local people about the metabolism of urban water, causes of river pollution, and to familiarize them with the capacity of soil and plants to respond to that problem. As part of its creation, the project provided diverse groups of people with opportunities to participate, including a group of Bronx youth who assisted in planting the wetland. Several of these apprentices will be involved in future monitoring of the effectiveness of the wetland in mitigating parking lot runoff. I use Isabelle Stengers' notion of ‘diplomacy’ to interrogate the efforts of the artist in negotiating and creating an occasion in which people with divergent interests can both recognize and maintain the relationships of care that sustain them. In effect, this effort extends the feminist discourse of maintenance work to include that undertaken by the ‘other-than-human’.     

历史时期的"黄河清"现象初探

古人对黄河清有“祥瑞之兆”和“不祥之征”两种观点。黄河澄清是一种自然现象,却又不可能出现在正常条件下,它有其内在的规律。只有当流域内大范围出现异常情况,如持续干旱少雨、冬季过于寒冷、地震等时,才会导致黄河河水变异,出现黄河澄清的现象。黄河清是干旱和黄河断流的前兆。同时,黄河清还与社会政治、化和生活交织在一起,成为奇异的化与社会现象。     

PRACTICING THE CULTURAL GREEN ECONOMY: WHERE NOW FOR ENVIRONMENTAL SOCIAL SCIENCE?

Debates concerning the development of the green economy necessarily focus on “upstream” issues that underpin the re‐structuring of national and regional economies through the lenses of financial, institutional and regulatory change. However, the growing interest in the cultural green economy requires a re‐scaling of debates surrounding the links that occur in complex socio‐technical systems, notably between individual consumers, social units and the architectures of the developing green economy. This necessitates a research and policy agenda that is attentive to both the complexities of such interactions (between structures, processes and practices) and the imperative to foster change in practices within wider society. This article explores the ways in which environmental social scientists have examined and evidenced these issues, arguing that two major barriers still exist for creating adequate understandings and opportunities for change. First, the overt focus on the individual consumer as a unit of measurement and political attention has stifled debate concerning the ways in which environmentally related social practices have developed in association with wider economic contexts. In this way, environmental social scientists have often failed to make the connections between individuals, practices and the economic system. Second, in adopting a largely individualistic perspective, environmental social scientists have tended to focus their attention on incrementalist and narrowly defined views of what ecological citizenship might look like and constitute in the green economy. The article therefore argues that environmental social scientists need to constructively engage in a new inter‐disciplinary dialogue about the role, purpose and ethics of citizen participation in developing and sustaining the green economy in an age of climate change and potential resource scarcity.
