Subjectivity,Power, and the IRB

A substantial literature in social sciences, including law and society, examines the intersections of research ethics and institutional review board (IRB) frameworks. Although geographers have engaged this literature, we argue that further involvement in ethical and regulatory discussions will advance opportunities for better understanding and negotiating the complex subjectivities produced in the IRB structure. Drawing on illustrative experiences of researchers, we focus specifically on the institutions convening IRBs, the researchers, and the human “subjects” produced in the IRB process. We conclude with a call for greater open discussion of the power dynamics, subjectivities, and challenges of formal ethical research structures.     

Material use,economic growth,and the environment

The three broad categories of commodity inputs to the economy are food, fuel, and material, defined as everything else not used for the first two purposes. Material provides physical structure, houses, cars, and packaging; is an important constitutent of modern agriculture in the form of fertilizer and insecticides; and supports the service sector through telecommunications and equipment and paper for our copying machines. The efficient flow of this material is an important factor in the U.S. economy.Correspondence should be directed to Earle B.

Diatom,pollen, and geochemical evidence for the palaeosalinity of Medicine Lake,S. Dakota,during the late-Wisconsin and early Holocene

Medicine Lake is a highly saline meromictic lake in eastern South Dakota. A lithostratigraphic and biostratigraphic study of the late-glacial and early post-glacial sediments shows that it was a relatively deep dilute freshwater lake during the period of the Picea pollen zone. When spruce forest changed to a Betula and then to a Quercus/Ulmus woodland in the early post-glacial period, the lake water became more concentrated but remained fresh. However, during the subsequent rapid transition to prairie in the early Holocene, when Gramineae, Ambrosia, and Artemisia dominated dry-land vegetation, the freshwater diatom flora was progressively replaced by a saline assemblage characterized by Cyclotella quillensis, Chaetoceros, and eventually Cyclotella caspia. The lake became permanently saline at about 9000 yr BP. A comparison of the fossil diatom assemblages with surface-sediment samples from a range of lakes in the Dakotas indicates that the change involved an increase in conductivity from about 500 S cm^–1 in the late-glacial period to > 10 000 S cm^–1 in the early Holocene. This rapid change is also marked by an abrupt increase in sulphate concentration in the sediment, the first appearance of bands of gypsum crystals, and the beginning of a well-laminated core sequence that continues through the remaining sediment record. Conditions of high salinity have prevailed to the present day.Contribution 299, Limnological Research Center.     

Looting, collecting, and the destruction of archaeological resources

Archaeological sites, the material remnants of our human past, are finite and nonrenewable cultural resources that are under constant threat from environmental forces, development activities, warfare, vandalism, and looting. Site looting is the destructive removal of archaeological objects to supply the art market. Looting is part of an economic system, the antiquities market, that works to supply the demand of collectors for archaeological objects. The destruction of archaeological resources by looters is an international crisis and threatens to obliterate the world’s cultural heritage and our ability to understand past cultures. The scale and intensity of the looting problem can be estimated by studying the extent of site destruction in countries of origin and by investigating the sources of antiquities held by collectors. Finding a solution to the problem of looting will require a focus on the demand side of the market (i.e., collectors) instead of the traditional focus on the supply side (looters, dealers)     

Policy Boosterism,Policy Mobilities,and the Extrospective City

Abstract

This study develops the notion of “policy boosterism,” a subset of traditional branding and marketing activities that involves the active promotion of locally developed and/or locally successful policies, programs, or practices across wider geographical fields as well as to broader communities of interested peers. It is argued that policy boosterism is (1) an important element of how urban policy actors engage with global communities of professional peers and with local residents, and (2) a useful concept with which to interrogate and understand how policies and policy knowledge are mobilized among cities. A conceptualization of policy boosterism and its role in global-urban policymaking is developed by combining insights from the burgeoning “policy mobilities” literature with those of the longstanding literature on entrepreneurial city marketing. It is supported by illustrative examples of policy boosterism in Vancouver: the city's Greenest City and Green Capital initiatives, the use of the term “Vancouverism” among the city's urban design community, and demonstrations of new urban technologies during the 2010 Winter Olympics that were used to market a particular vision of the city's governance to people from elsewhere, but also—crucially—to local audiences. The article concludes by highlighting four foci that might frame future work at the intersections of policy boosterism and policy mobilities.     

The city,the (Member) state,and the European Union

This contribution to a Debate on “The Nation-State and the city” foregrounds the recently adopted Urban Agenda for the European Union. It discusses the new role of cities in the European policy making process and its relevance for relations between State and City in the light of EU membership.     

Tessellons,topography, and glaciations on the Qinghai-Tibet Plateau

The Qinghai-Tibet Plateau has developed into a vast fortress-like structure that has recently presented a barrier limiting the egress of moisture-bearing air masses. Lower sea levels also affected the climate. This paper examines their effects on the current evidence for the timing of past glaciations, and the development and evolution of permafrost. There are two theories regarding glaciation on the Qinghai-Tibet Plateau(QTP). Kuhle suggested that there was a major, unified ice-cap during the Last Glacial Maximum(LGM), whereas major Chinese glaciologists and others have not found or verified reliable evidence for this per se. There have been limited glaciations during the last 1.1 Ma B.P. but with increasing dominance of permafrost including both primary and secondary tessellons infilled with rock, sand or loess. The East Asia Monsoon was absent in this area during the main LGM, starting at 30 ka B.P. on the plateau, with sufficient precipitation reappearing about 19 ka B.P. to produce ice-wedges. A weak Megathermal event took place between 8.5 and 6.0 ka B.P., followed by Neoglacial events exhibiting peak cold at 5.3–4.7 ka, 3.1–1.5 ka, and the Little Ice Age(LIA) after 0.7 ka. Subsequently,mean annual air temperature has increased by 4 °C.     

Invisible homelessness: anonymity,exposure, and the right to the city

The city of Denver, Colorado recently outlawed camping in all open space. Part of a broad effort to accelerate the profit potential of prime urban land through real estate speculation and commerce, the camping ban has dislocated homeless people from the city’s marginal spaces. Based on ethnographic fieldwork and archival research in Denver, this article develops a tripartite approach to public space—prime, everyday, and marginal—to analyze challenging ways in which people who are homeless in Denver must now manage their exposure to others in everyday public spaces. In addition to eliminating places of hard-won safety and security, this singular new code disrupts hygiene, mobility, and sociability routines, thus throwing already precarious lives into further disarray by rendering housing status visible. To demonstrate how everyday social justice springs from interaction between different people co-present in public space, we foreground the voices of Denver’s homeless people, those most impacted by quality of life laws. Evicting individuals from marginal spaces and rendering them visibly homeless in everyday and prime spaces, the ban deprives them of a fundamental right to the city: anonymity.     

Soy,Cotton, and the Final Atlantic Forest Frontier

From 1945 to 2000, the extent of Paraguay's Atlantic Forest was reduced from 73,000 to 12,000 square kilometers. Deforestation rates were exceptionally high from the late 1960s through to the end of the century. During this period, dual agricultural frontiers pushed into the region from both east and west, resulting in a production landscape defined by two principal commodities: soybeans and cotton. This article considers the expansion and contraction of these industries and addresses their impacts on the region's forest cover. Findings suggest that the role of cotton and smallholder agriculture has been greatly diminished as a driver of land cover change in the region since 1990. High rates of forest loss were sustained, however, partly as a result of continued pressure for agricultural expansion for soy production.     

Response and recovery of the Eel River, California, and its tributaries to floods in 1955, 1964, and 1997

Northwestern California is prone to regional, high magnitude winter rainstorms, which repeatedly produce catastrophic floods in the basins of the northern Coast Ranges. Major floods on the Eel River in 1955 and 1964 resulted in substantial geomorphic changes to the channel, adjacent terraces, and tributaries. This study evaluated the changes and the effects of a moderate flood in 1997 through field observations and examination of aerial photographs that spanned from 1954 to 1996. The purpose was to document the nature and magnitude of geomorphic responses to these three floods and assess the rates and controls on the recovery of the Eel River and its tributaries. Channel widening from extensive bank erosion was the dominant geomorphic change along the lower Eel River during major floods. As a result of the 1964 flood, the largest amount of widening was 195 m and represented an 80% change in channel width. Channel narrowing characterized the periods after the 1955 and 1964 floods. More than 30 years after the 1964 flood, however, the river had not returned to pre-flood width, which suggests that channel recovery required decades to complete. A long recovery time is unusual given that the Eel River is located in an area with a “superhumid” climate and has an exceptionally high sediment yield. This long recovery time may reflect highly seasonal precipitation and runoff, which are concentrated in 3–5 months each winter. In contrast to the main stem of the Eel River, the dominant effects of floods on the tributaries of the Eel River were rapid aggradation of channel bed and valley floor followed by immediate downcutting. Dendrogeomorphic data, aerial photographs, and field observations indicate that thick wedges of gravel, derived largely from hillslope failures in upper reaches of the tributaries, are deposited at and immediately upstream of the mouths of tributaries as the stage of the Eel River exceeded that of the tributaries during major floods. In the waning stages of the flood, the tributaries cut through the gravel at a rate equal to the lowering of the Eel and generated unpaired terraces and nickpoints. The complete process of deposition and incision can occur within a few days of peak discharge. Although reworking of some sediment on the valley floor may continue for years after large floods, channel morphology in the tributaries appears to be a product of infrequent, high magnitude events. The morphology of the tributary channel also appears to be greatly influenced by the frequency and magnitude of mass wasting in headwater areas of small basins.
