ANTHROPOCENE TIME

Beginning with the question of how a sense of geological time remains strangely withdrawn in contemporary discussions of the Anthropocene in the human sciences and yields place to the more human‐centered time of world history, this article proceeds to discuss the differences between human‐historical time and the time of geology as they relate to the concept of the Anthropocene. The article discusses the difficulty of developing a mode of thinking about the present that would attempt to hold together these two rather different senses of time and ends with a ground‐clearing exercise that might enable the development of such thought.     

Viewing obesogenic advertising in children's neighbourhoods using Google Street View

The advertising of unhealthy food and beverages forms an important component of obesogenic environments. Such marketing to children is a key health determinant because of its impact on dietary preference and food purchasing behaviour. The location of outdoor advertising is important in exploring obesogenic environments and children's neighbourhoods. The aim of this study is to explore issues involved in the use of Google Street View to examine outdoor food and beverage advertising. The implications for using Google Street View in the context of neighbourhood built environment research and grass‐roots advocacy are discussed. The study was conducted within walkable distances from 19 primary and intermediate schools in Auckland, New Zealand, where “walkable” was defined as limited by 800 m road network boundaries, which are equivalent to school buffer boundaries. Google Street View allows for centrality of data collection, coding, and storage. However, challenges exist with the method because 727 (29.4%) of a total of 2,474 outdoor advertisements that were identified were not able to be categorised because images were unclear, not in English, blocked, or at angles where detail cannot be deciphered. Specific to outdoor advertising for food and beverages, the results presented here show that children are exposed to a significantly greater number of unhealthy advertising than other advertising, P=0.001, eta‐squared statistic (0.45) indicates a large effect size. Overall, the results show promise for the use of Google Street View in the study of obesogenic environments.

Drawing the line with Google Earth: the place of digital mapping outside of geography

The Te Kawa a Māui Atlas project explores how mapping activities support undergraduate student engagement and learning in Māori studies. This article describes two specific assignments, which used online mapping allowing students to engage with the work of their peers. By analysing student evaluations of these activities, we identify four aspects that benefit student engagement: mapping diversifies the learning experience; mapping promotes acquisition of a different skill set; online mapping allowed more open sharing of work and; mapping promotes place-based learning. Some students were ambivalent about the assignments, so mapping should only be used to support other learning objectives.     

Using GIS in an Earth Sciences field course for quantitative exploration,data management and digital mapping

Field courses are essential for subjects like Earth Sciences, Geography and Ecology. In these topics, GIS is used to manage and analyse spatial data, and offers quantitative methods that are beneficial for fieldwork. This paper presents changes made to a first-year Earth Sciences field course in the French Alps, where new GIS methods were introduced. Students use GIS in preparation to explore their research area using an elevation model and satellite images, formulate hypotheses and plan the fieldwork. During the fieldwork, a pilot group managed their field-observations using GIS and made digital maps. Students praise the use of quantitative digital maps in the preparation. Students made use of the available techniques during the fieldwork, although this could be further intensified. Some students were extra motivated due to the technical nature as well as the additional analytical possibilities. The use of GIS was experienced as a steep learning curve by students, and not all staff members are confident in supervising students using GIS, which calls for a sufficient preparation and training of both students and staff. The use of GIS adds abstract analyses and quantitative assessment, which is a complementary learning style to fieldwork that mostly focuses on practical skills.     

An Informational Right to the City? Code,Content, Control,and the Urbanization of Information

Henri Lefebvre talked of the “right to the city” alongside a right to information. As the urban environment becomes increasingly layered by abstract digital representation, Lefebvre's broader theory warrants application to the digital age. Through considering what is entailed by the urbanization of information, this paper examines the problems and implications of any “informational right to the city”. In directing Tony Benn's five questions of power towards Google, arguably the world's most powerful mediator of information, this paper exposes processes that occur when geographic information is mediated by powerful digital monopolies. We argue that Google currently occupies a dominant share of any informational right to the city. In the spirit of Benn's final question—“How do we get rid of you?”—the paper seeks to apply post‐political theory in exploring a path to the possibility of more just information geographies.     

于阗的地神图像及其流变

于阗是著名的西域古国,汉唐时期佛教及其艺术在其地兴盛一时。本文主要围绕一百余年来在新疆和田地区发现的多件地神图像,结合文献,探讨了此类图像的外在形式、文献依据及其所反映的思想内涵。作者认为,于阗佛寺的地神图像是据《金光明经·坚牢地神品》绘制,它影响了龟兹和敦煌佛教绘画的王族供养人画像,反映了出身为世俗人的王族供养人试图藉此神化自我,宣扬王权天授的思想。     

Google Earth, GIS and stone-walled structures in southern Gauteng, South Africa

In South Africa, air photos were used in the 1960s and 1970s to plot distribution maps of pre-colonial stone-walled structures in order to study the peopling of this landscape. Different architectural styles of stone-walled structures were attributed to different cultures, who shared a mixed agricultural and pastoralist economic base and a cattle centered world-view. New technologies such as Google Earth satellite imagery as well as Geographic Information System software justify revisiting these structures as they facilitate more complex analyses of larger databases. The spatial analysis of remotely sensed settlement data from the Suikerbosrand Nature Reserve near Johannesburg shows significant changes in settlement patterns from dispersed homesteads to nucleated towns during the last two or three centuries before colonial times. These changes echo similar patterns reported in the neighboring North West Province, where they have been interpreted as a sequence of evolution in social, political and economic complexity. In the Suikerbosrand reserve climate change, conflict and other factors may have helped bring about the observed changes in settlement patterns.     

苏南土墩墓的初步研究

一、前言 长江下游地区的江苏南部,无论是丘陵、山地还是平原地区,常能见到象馒头状凸出地面的大小土墩,且这些土墩又常成群连片地集中出现。这些土墩大多数是人工堆筑而成的古代墓葬,也就是目前人们通常所说的“土墩墓”①。这类土墩墓可以分为两种类型：一种是用石块垒砌墓室的土墩墓,称之为“石室土墩”②,主要分布在环太湖地区的山巅及浙江北部太湖之滨;另一种是无石室结构的土墩墓,称之为“土墩墓”,遍布于苏南地区。本文所要讨论的是无石室结构的土墩墓,其年代约当中原地区西周前期到春秋战国之际③。这些土墩墓是商周时期…     

THE ANTHROPOCENE AND THE PLANET

Dipesh Chakrabarty's The Climate of History in a Planetary Age is, in three respects, far more than a synthesis of over a decade of pioneering conceptual work aimed at making sense of the Anthropocene/planetary predicament and its implications for historical understanding. First, the book makes visible an intellectual trajectory in which Chakrabarty's conceptual struggles with the Anthropocene gradually move from the centrality of the notion of the Anthropocene toward the centrality of the notion of the planet. Second, it highlights the relational complexities with which one needs to grapple when trying to make sense of the current predicament. Third, and finally, the book showcases a series of often overlapping conceptual distinctions that Chakrabarty has developed while navigating these complexities. Through a discussion of the above key aspects, this review essay highlights the achievements of The Climate of History in a Planetary Age and critically engages with its central themes. In dialogue with the book, it pays special attention to exploring the respective benefits and drawbacks of the notions of the Anthropocene and the planet, and to the character and role of human agency in the Anthropocene/planetary predicament. Finally, the essay concludes with a few thoughts concerning the question of what kind of a reinvention of historical understanding might be triggered, respectively, by the notions of the Anthropocene and the planet.
