Geographies of Algorithmic Violence: Redlining the Smart City

City governments are embracing data-driven and algorithmic planning to tackle urban problems. Data-driven analytics have an unprecedented capacity to call urban futures into being. At the same time, they can depoliticize planning decisions. I argue that this shift calls urban studies scholars to investigate geographies of algorithmic violence—a repetitive and standardized form of violence that contributes to the racialization of space and spatialization of poverty. This article examines this broader phenomenon through the case of a proprietary market value assessment that is being used to guide development in cities across the United States. The assessment employs an algorithm that helps city officials make critical decisions about which neighborhoods to target for investment, disinvestment and public service upgrades or disconnections. I argue that the racial, infrastructural, and epistemological violence associated with this evaluation can potentially lead to a new kind of municipal redlining. The article brings insights from critical race theory into conversation with critical scholarship on algorithms by analyzing how algorithmic violence works through data-driven planning technologies to depoliticize and leverage power while further entrenching racism and inequality.     

Tent City: Patterns of Informality and the Partitioning of Sacramento

Unsanctioned tent cities are increasing in number in cities throughout the western United States. Scholars explain the phenomenon as homeless people asserting their ‘right to the city’ or as ‘managed marginality’. These explanations capture much of the socio-political relationship between local government and homeless populations, but do not explain the long-term persistence of tent cities and the fluctuating nature of their visibility. A spatial history of informal encampments in Sacramento at three key moments—the founding of the city, the Great Depression and the Great Recession—reveals a long-term ebb and flow of tent cities occupying close-to-the-center, urban vacancies. Urban vacancies arise from the partitioning of the city into specific purposes, places and people, a taken-for-granted perception of how cities should be. The visibility of tent cities disrupts this aesthetic notion of stability and growth as homeless people use the tent to protest their isolation and exclusion.

Accounting and Finance: authorship and citation trends

Accounting and Finance (A&F ) has experienced a surge in published research in the last decade. The analysis here reveals a marked increase in the number of published articles in A&F since 2003, a distinct trend for published papers to have a larger number of authors, a significant and stable contribution by the top 5 Australian accounting/finance departments, as well as a notable increase in contribution from non‐US foreign universities, particularly those located in the UK, Canada, Hong Kong, Singapore and Spain. An analysis of citations indicates the increasing impact of A&F in recent years.     

How does attachment style influence the brand attachment – brand trust and brand loyalty chain in adolescents?

This study contributes to the growing body of literature investigating how and why consumers form connections to brands by applying an attachment theoretical framework. According to the attachment theory, children develop internal working models of the reliability of others in the interaction with the primary caregiver(s). It can be assumed that this attachment style, which is conceptualized along two dimensions (secure–anxious and dependent–independent), not only influences intimate relationships in the long run, but may also play an important role in customer relationships. The author investigates the influence of attachment style along the brand attachment – brand trust and brand loyalty chain. The sample consists of 216 adolescents. The results derived from structural equation modeling (SEM) by proposing a non-recursive model show that the dependent–independent dimension of parental attachment style positively influences the corresponding dimension of brand attachment predisposition and is important for all of the constructs along the brand attachment – brand trust and brand loyalty chain. However, this is not the case with the secure–anxious dimension of parental attachment style. The secure–anxious dimension of brand attachment predisposition does, on the other hand, have a significant impact at least on brand trust. The results are discussed from an attachment theoretical point of view and corroborate the suppositions of Rindfleisch, Burroughs, and Wong (2009 Rindfleisch, Aric, James E. Burroughs, and Nancy Wong. 2009. The safety of objects: Materialism, existential insecurity, and brand connection. Journal of Consumer Research 36 (1): 1–16.[Crossref], [Web of Science ®] , [Google Scholar]), who grounded their findings on terror management theory. Several possible implications of these results for the theory and practice of brand management and advertising, especially in the light of the gamification of advertising, are discussed.     

一种基于Edline线特征的车道线识别算法

为了提升车道线检测的准确性和实时性,改良车道偏离预警系统的性能,提出了一种新的车道线识别算法。首先应用投影法对采集到的图像设立感兴趣区域,以此来减少图像中存在的干扰信息;其次应用一种改进后的自适应高斯滤波算法对采集所得图像进行平滑处理,减少图像中不必要的细节;最后采用边缘绘制算法进行边缘检测,在此基础上,提出一种线段检测算法——Edline算法提取边缘线,对检测到的直线段进行筛选和聚类。利用引用计数法对车道线进行跟踪和预测。结果表明,新算法的平均处理时间为17.1 ms,准确率为96.19%,将其应用在车道偏离预警系统中可以有效地提高预警效率,提升预警的准确性和响应速度。研究结果丰富了车道线识别理论,可为车道偏离预警系统的应用及基础研究提供参考。     

上部覆盖层下伏页岩一类潜在滑坡演化变形机制分析

为研究上部覆盖层下伏页岩这一类型的滑坡失稳变形,需要确定其变形的潜在影响因素,从定量角度上分析这一类型滑坡灾害的变形演化问题。以容县六王镇西流河潜在滑坡为研究对象,借助钻孔勘探、室内试验和地质调绘,详细分析了西流河滑坡的工程地质概况,并推测其可能的变形演化机制,然后利用Geostudio数值软件建立西流河滑坡的渗流模型,模拟其在不同降雨工况下的渗流规律。研究发现:西流河滑坡在持续降雨过程中稳定性系数从1.224逐步降低至1.09,稳定性系数不断下降,滑坡体内由垂直入渗逐步转化沿滑动带稳定渗流;当遭遇极端暴雨情况(50年重现期)时,滑坡体内稳定渗流场显著增厚,饱和滑带土增多,滑坡安全储备达到极限。由此可以得出:上部覆盖层下伏页岩一类滑坡变形演化过程主要分滑坡体上部覆盖层堆积阶段,垂直入渗至页岩富水软化阶段和稳定渗流至潜在滑动带软化蠕变这3个阶段;其中上部覆盖层的高渗透性和下伏页岩的隔水特征是导致页岩风化带软化蠕变和稳定渗流场形成的关键因素。研究结果为上部覆盖层下伏页岩这一类滑坡影响因素的研究提供了一些证据,对研究滑坡演化变形机制具有借鉴意义。

政府规制与中国稀土产品出口增长的二元边际——对2001—2012年微观贸易数据的实证分析

采用HS?6位数级微观贸易数据,计算2001—2012年中国稀土产品出口增长的二元边际,并进一步分析相对出口规制程度、相对产量与出口增长二元边际之间的相互影响,结果表明：中国稀土产品出口规制政策对稀土产品出口增长的集约边际和扩展边际都有促进作用,其中对集约边际的影响更大;而相对产量对二元边际有负面影响。在中国经济新常态下,随着稀土产品出口规制政策的逐步弱化,应加强对稀土产业的生产规制,提高产品附加值,实现从规模速度型粗放增长向质量效率型集约增长的转变;并积极开拓新的出口市场,促进稀土产业的良性扩张。
