Family photography is now more popular than ever thanks to technological advances which allow the storing and sharing of vast numbers of pictures. Here, case study material drawn from the UK offers a ...deeper understanding of both domestic family photographs and their public display. Recent work in material culture studies, geography, and anthropology is used to approach photographs as objects embedded in social practices, which produce specific social positions, relations and effects.
► We examine the impacts of climate change on soybean and spring wheat using a crop model. ► Climate model uncertainty is represented by 14 different climate models. ► Impact varies by crop, ...location, climate model and with adaptation.
Crop production is inherently sensitive to fluctuations in weather and climate and is expected to be impacted by climate change. To understand how this impact may vary across the globe many studies have been conducted to determine the change in yield of several crops to expected changes in climate. Changes in climate are typically derived from a single to no more than a few General Circulation Models (GCMs). This study examines the uncertainty introduced to a crop impact assessment when 14 GCMs are used to determine future climate. The General Large Area Model for annual crops (GLAM) was applied over a global domain to simulate the productivity of soybean and spring wheat under baseline climate conditions and under climate conditions consistent with the 2050s under the A1B SRES emissions scenario as simulated by 14 GCMs.
Baseline yield simulations were evaluated against global country-level yield statistics to determine the model's ability to capture observed variability in production. The impact of climate change varied between crops, regions, and by GCM. The spread in yield projections due to GCM varied between no change and a reduction of 50%. Without adaptation yield response was linearly related to the magnitude of local temperature change. Therefore, impacts were greatest for countries at northernmost latitudes where warming is predicted to be greatest. However, these countries also exhibited the greatest potential for adaptation to offset yield losses by shifting the crop growing season to a cooler part of the year and/or switching crop variety to take advantage of an extended growing season. The relative magnitude of impacts as simulated by each GCM was not consistent across countries and between crops. It is important, therefore, for crop impact assessments to fully account for GCM uncertainty in estimating future climates and to be explicit about assumptions regarding adaptation.
This paper addresses how geographers conceptualize cultural artifacts. Many geographical studies of cultural objects continue to depend heavily on an approach developed as part of the ‘new cultural ...geography’ in the 1980s. That approach examined the cultural politics of representations of place, space and landscape by undertaking close readings of specific cultural objects. Over three decades on, the cultural field (certainly in the Global North) has changed fundamentally, as digital technologies for the creation and dissemination of meaning have become extraordinarily pervasive and diverse. Yet geographical studies of cultural objects have thus far neglected to consider the conceptual and methodological implications of this shift. This paper argues that such studies must begin to map the complexities of digitally-mediated cultural production, circulation and interpretation. It will argue that, to do this, it is necessary to move away from the attentive gaze on stable cultural objects as formulated by some of the new cultural geography, and instead focus on mapping the dynamics of the production, circulation and modification of meaning at digital interfaces and across frictional networks.
Accounts by geographers of the ways in which urban spaces are digitally mediated have proliferated in the last few years. This significant body of work pays particular attention to the production of ...urban space by software and digital hardware, and geographers have drawn on various kinds of posthumanist philosophies to theorize the agency of the technological nonhuman. The agency of the human, however, has been left undertheorized in this work, often appearing in the form of excessive resistance to the agency granted to the digital. This article contributes to understanding the digital mediation of cities by theorizing a specifically posthuman agency; that is, a human agency both mediated through technics and diverse. Drawing on the philosophy of Stiegler as well as a range of feminist digital scholarship, the article conceptualizes posthuman agency as always already coconstituted with technologies. Posthumans are simultaneously individuated and exteriorized in that coconstitution, and this permits agency understood as reinvention. The article also insists that such sociotechnical agency is differentiated, particularly in terms of the spatialities and temporalities through which it is organized. It concludes by arguing that geographers must reconfigure their understanding of digitally mediated cities and acknowledge the inventiveness and diversity of urban posthuman agency.
OBJECTIVE: To understand the efficacy of vaginal dilators in the management of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. DESIGN: Retrospective sequential study. SETTING: Hospital. PATIENT(S): ...245 women. INTERVENTION(S): Vaginal dilators. MAIN OUTCOME MEASURE(S): Functional vaginal length and sexual satisfaction. RESULT(S): Of the patients who completed the program, 232 (94.9%) achieved a successful vaginal length (defined as greater than 6 cm in length and maximum width throughout the vagina and especially at the apex) and sexual function. When the program was completed by all patients, 100% of patients were successful. CONCLUSION(S): Vaginal dilator therapy is the treatment of first choice for creation of the vagina in MRKH syndrome, and the success rates suggest that surgery is rarely, if ever, required.
Global surface temperature is projected to warm over the coming decades, with regional differences expected in temperature change, rainfall and the frequency of extreme events. Temperature is a major ...determinant of crop growth and development, affecting planting date, growing season length and yield. We investigated the effects of increments of mean global temperature warming from 0.5 °C to 4 °C on soybean and maize development and yield, both globally and for the main producing countries, and simulated adaptation through changing planting date and variety. Increasing temperature resulted in reduced growing season lengths and ultimately reduced yields for both crops. The global yield for maize decreased as temperature increased, although the severity of the decrease was dependent on geographic region. Small temperature increases of 0.5 °C had no effect on soybean yield, although yield decreased as temperature increased. These negative effects, however, were partly compensated for by the implementation of adaptation strategies including planting earlier in the season and changing variety. The degree of compensation was dependent on geographical area and crop, with maize adaptation delaying the negative effects of temperature on yield, compared to soybean adaptation which increased yield in China, India and Korea DPR as well as delaying the effects in the remaining countries. The results of this paper indicate the degree to which farmer-controlled adaptation strategies can alleviate the negative impacts of increasing temperature on two major crop species.
One of the most striking developments across the social sciences in the past decade has been the growth of research methods using visual materials. It is often suggested that this growth is somehow ...related to the increasing importance of visual images in contemporary social and cultural practice. However, the form of the relationship between ‘visual research methods’ and ‘contemporary visual culture’ has not yet been interrogated. This paper conducts such an interrogation, exploring the relation between ‘visual research methods’ – as they are constituted in quite particular ways by a growing number of handbooks, reviews, conference and journals – and contemporary visual culture – as characterized by discussions of ‘convergence culture’. The paper adopts a performative approach to ‘visual research methods’. It suggests that when they are used, ‘visual research methods’ create neither a ‘social’ articulated through culturally mediated images, nor a ‘research participant’ competency in using such images. Instead, the paper argues that the intersection of visual culture and ‘visual research methods’ should be located in their shared way of using images, since in both, images tend to be deployed much more as communicational tools than as representational texts. The paper concludes by placing this argument in the context of recent discussions about the production of sociological knowledge in the wider social field.
Insight into the evolution of Philippine Sea‐South China Sea (SCS) plate motions helps reveal the driving mechanisms of the long‐term tectonic complexity in Southeast Asia. Here, based on the ...integration of the most recent geological and seismic data, we present a new plate reconstruction model for this region characterized by back‐arc extension and subduction since the Eocene. We suggest that the western boundary of the Philippine Sea Plate was a constant sinistral strike‐slip fault at 55–22 Ma with a clockwise self‐rotation. The connection between the SCS and Shikoku Ridges possibly initiates at 30 Ma, when their spreading times overlapped indicating an affinitive origin and magma source. Regional‐scale geodynamic simulations interfaced with our reconstructed plate motion indicate that the seismic high‐velocity body under the SCS is likely to be the leading edge of the Pacific Slab.
Plain Language Summary
Since 55 million years ago, East Asia has been going through a complex plate recombination. Several quantitative plate motion models have been published, but there remain several irrationalities, for example, a footwall plate was moving away from the trench. We established a new model for the Philippine Sea‐South China Sea (SCS) region as an improvement. Our model provides a smooth movement of the Philippine Sea Plate (PSP) from the equatorial zone to its present position, with a clockwise rotation. Based on it, we deduce: (a) the western boundary of the PSP was a sinistral strike‐slip fault; (b) the spreading ridges in SCS and Shikoku Basin were connected at 30 Ma; (c) the stagnant slab under the SCS is a part of the subducting Pacific Slab.
