A Road to Conflict: Stakeholder’s and Social Network Analysis of the Media Portrayals of a Social-Environmental Conflict in Bolivia

Society’s understanding of a conflict is mediated by information provided in mass media, for which researchers stress the importance of analyzing media portrays of stakeholders in a conflict. We analyze information from the Bolivian press regarding the construction of a road crossing the Isiboro-Sécure Indigenous Territory and National Park (TIPNIS). Using stakeholder’s and social network analyses, we explore stakeholder’s positions and alliances as represented in the media and contrast it with previous scholarly work. We found that some actors cited as central in scholar analyses of the conflict are largely absent in the media (e.g., private investors, conservationist sector) and that the media tend to present stakeholders as having more homogeneous positions than the academic literature does while also neglecting some important alliances in their account. The media also suggests that Indigenous communities are forging stronger alliances with urban sectors and civil society, alliances not stressed by researchers.     

“We Don’t Equal Even Just One Man”: Gender and Social Control in Conservation Adoption

Women own or co-own approximately half of the farmland in Iowa, United States, yet researchers are only beginning to study these landowners’ social relationships in relation to their land. This study analyzes qualitative data collected in Iowa through a series of meetings hosted by the Women, Food and Agriculture Network (WFAN). I find that social control through exclusion constrains women landowners’ access to information about and implementation of conservation. Specifically, I identify how women landowners experience the social processes of boundary maintenance and othering in land management. These processes create barriers to conservation adoption and maintain gendered agricultural landscapes. The women who participated in WFAN’s conservation programs express their experience of and resistance to dominant narratives as they attempt to create landscape change. These findings highlight the importance of further study of inequality processes and their relation to control of farmland if conservation goals are to be met.     

Constructing the Klamath: Nature,Culture, and the Management of a Western River

Despite decades of scientific research, stakeholder negotiations, and policy proposals, management of the Klamath River in southern Oregon and northern California remains hotly contested. This research examines the sociocultural dimensions of proposed removal of four Klamath River dams. Using a social constructivist approach to analyze the discourse of public comments regarding dam removal, I find commenters rely on diverse ideas of nature and divergent problem framings, contest the role of science, and draw on embedded and meaningful sociocultural narratives to legitimize their management preferences. These discourses shape the terrain upon which management actions are perceived, valued, and contested, and make management actions meaningful beyond their immediate spatial and temporal context. Dam removal on the Klamath River is far more than an ecological problem amenable to a scientific or technical approach; instead, it is a complex project shot through with the sociocultural identities, visions, and narratives of all involved.     

Gatekeepers,Shareholders, and Evangelists: Expanding Communication Networks of African American Forest Landowners in North Carolina

The Sustainable Forestry and African American Land Retention Program (SFLR) was launched in 2012 to increase adoption of sustainable forestry practices among African American landowners in the southeastern United States to prevent land loss, increase forest health, and build economic assets. One of its main goals was to build communication networks through which African American landowners could obtain and share information about forestry practices and landowner assistance programs independent of public agencies. To measure and examine the growth of these communication networks over a three-year period (2014-2017), we conducted 87 interviews with landowners (24 of whom were interviewed multiple times), SFLR personnel, and Federal and State staff members in North Carolina. We used complementary methods of data gathering and analysis, including social network analysis and qualitative analysis. Our results showed expanding communication networks will be sustained independently of the program over time, although there is still a heavy reliance on program personnel.     

国外乡村空间研究的进展与启示

任何空间都是社会的产物。在工业化、城镇化、信息化和政策的驱动下,中国乡村空间正在发生剧烈重构。乡村空间研究作为国外乡村地理学研究的核心内容之一,具有多学科、多视角、多维度、多方法的特点,形成了一个丰富的研究图景。为了更全面地把握国外乡村空间研究的进展,论文对国外近40 a的乡村空间研究文献进行了梳理。研究发现,国外学者从物质、想象和实践等层面诠释了乡村空间的内涵,并通过建立“乡村空间的三重模型”,强调了日常生活实践的重要性,引入了生活空间,构建了较为系统的乡村空间研究架构。在理论视角上,国外乡村空间研究经历了功能主义、政治经济学和社会建构主义3个阶段;在时间的演进上,实现了由生产主义空间研究到后生产主义空间研究的转换;在空间维度上,实现了聚落空间、经济空间、社会空间和文化空间的多重叠加。国外乡村空间研究实现了从物质层面到社会表征、从客体性空间到主体性空间、从静态单维空间到动态多维空间的转变,启示我们对乡村空间进行跨学科研究以及“社会-文化”研究的重要性。中国乡村空间建设要重视农民的主体性地位、强调乡村空间的多功能性、尊重乡村空间的“地域性”和“差异性”、恢复乡村空间的意义生产功能。

Integration of nighttime light remote sensing images and taxi GPS tracking data for population surface enhancement

The population distribution grid at fine scales better reflects the distribution of residents and plays an important role in investigating urban systems. The recent years have witnessed a growing trend of applying the nighttime light data to the estimation of population at micro levels. However, using the nighttime light data alone to estimate population may cause the overestimation problem due to excessively high light radiance in specific types of areas such as commercial zones and transportation hubs. In dealing with this issue, this study used taxi trajectory data that delineate people’s movements, and explored the utility of integrating the nighttime light and taxi trajectory data in the estimation of population in Shanghai at the spatial resolution of 500 m. First, the initial population distribution grid was generated based on the NPP-VIIRS nighttime light data. Then, a calibration grid was created with taxi trajectory data, whereby the initial population grid was optimized. The accuracy of the resultant population grid was assessed by comparing it with the refined survey data. The result indicates that the final population distribution grid performed better than the initial population grid, which reflects the effectiveness of the proposed calibration process.     

Building a model-based personalised recommendation approach for tourist attractions from geotagged social media data

When travelling, people are accustomed to taking and uploading photos on social media websites, which has led to the accumulation of huge numbers of geotagged photos. Combined with multisource information (e.g. weather, transportation, or textual information), these geotagged photos could help us in constructing user preference profiles at a high level of detail. Therefore, using these geotagged photos, we built a personalised recommendation system to provide attraction recommendations that match a user's preferences. Specifically, we retrieved a geotagged photo collection from the public API for Flickr (Flickr.com) and fetched a large amount of other contextual information to rebuild a user's travel history. We then created a model-based recommendation method with a two-stage architecture that consists of candidate generation (the matching process) and candidate ranking. In the matching process, we used a support vector machine model that was modified for multiclass classification to generate the candidate list. In addition, we used a gradient boosting regression tree to score each candidate and rerank the list. Finally, we evaluated our recommendation results with respect to accuracy and ranking ability. Compared with widely used memory-based methods, our proposed method performs significantly better in the cold-start situation and when mining ‘long-tail’ data.     

Method for evaluating the degrees of land use sustainability of mountainous county and its application in Yunnan Province,China

The evaluation of sustainable land use is the key issue in the field of studying the sustainable land utilization. In general analysis, the sustainable land use is evaluated respectively from its ecological sustainability, economic sustainability and social sustainability in China and other countries in recent years. Although this evaluation is an important work, it seems insufficient and hard to comprehensively reflect the whole degree of land use sustainability. Thus, to make up this deficiency, this paper brings forward the evaluation indexes, which make it possible to quantitatively reflect the whole degree of land use sustainability, namely, the concept of ＂degrees of overall land use sustainability＂ （Dos）, and research and measurement development of the method of and calculation in Dos. Taking the evaluation of the degree of land use sustainability in county regions of Yunnan Province as the actual example for analysis, results are basically as follows：
1） The degree of land use sustainability （Dos） is the ration index to organically and systematically integrate the degree of ecological friendliness （DeF）, the degree of economic viability （Dev） and the degree of social acceptability （Dsa）, able to comprehensively reflect the whole sustainability degree of regional land use
2） Based on the value of Dos, the grading system and standard for the sustainability of land use may be established and totally divided into five grades, namely, the high-degree sustainability, middle-degree sustainability, low-degree sustainability, conditional sustainability and non-sustainability. Meanwhile, the standard for distinguishing sustainability grades has also been confirmed so as to determine the nature of sustainability degrees in different grades. This makes the possibility for the combination of nature determination with ration in research result and provides with the scientific guideline and decision-making gist for better implementation of sustainable land use strategy.
3） The pract
