利用北京社会调查、法律文书、兴趣点、路网、定位数据,发现盗窃及暴力犯罪密度对犯罪恐惧感并无显著关联或影响偏弱,犯罪活动与犯罪恐惧感存在“匹配且具高安全性”“匹配且具高危险性”“不匹配且比主观感知更危险”“不匹配且比主观感知更安全”等类型。脆弱人群更易高估安全风险;防卫空间及街道眼理论分别适用于解释客观犯罪和主观感知,高密度、混合型、密路网的可渗透环境容易产生比主观感知更危险的情形;物理与社会失序、居住不稳定性会产生比主观感知更安全的情形;高人员流动性及高地位社区的居民则易低估安全风险;出入管控和环境维护能起到减犯罪、降恐惧的双重作用。 相似文献

Summary This paper argues that the study of crime and the fear of crime in rural areas reveals much about the geography of crime, policing and rural society. Drawing upon a crime and safety survey conducted with residents of a rural parish in Worcestershire it establishes a link between fear of crime and 'cultural threats' to residents' dominant constructions of rurality. It concludes by considering the 1998 Crime and Disorder Act and its implications for rural policing and society. 相似文献

Borrowing methods from epidemiology, studies of spatiotemporal regularities of crime have been booming in various industrialized countries. However, few such attempts are empirical studies using crime data in developing countries due to a lack of data availability. Utilizing a recent burglary dataset in Wuhan, the fourth largest city in China, current research applied the sequential kernel density estimation and the space–time K-function methods to analyze the spatiotemporal changes of hotspots of residential burglaries. The results show that, both spatial and spatiotemporal clustering exists. The hotspots were relatively stable over time. The space–time clustering, however, shows significant concentrations both in space and over time. In addition, analytic results show significant effects of distance decay in terms of occurrences of burglary incidents along the spatial and temporal dimensions. Moreover, findings from the research provide critical information on the space–time rhythm of crime, and therefore can be utilized in crime prevention practice. Finally, the implications of the findings and limitations are discussed. 相似文献

This paper examines the spatial and social distribution of the fear of crime and the relationships of such fear with aspects of the environment. Through an analysis of a questionnaire survey conducted in a variety of areas in Stoke-on-Trent in the English Midlands, it considers both the causes of the fear of crime and the associations that have been identified with other dimensions shaping vulnerability. It concludes by offering some guidance on how to address the differences between those populations who fear crime most and those who are most vulnerable. 相似文献

Summary The recent British Crime Surveys have confirmed that there are significant spatial variations in the distribution of crime risk. However, it is notoriously difficult to represent the spatial patterns in Britain convincingly, owing to the statistical inadequacy of the official crime data. This paper discusses the use of home contents insurance data as a proxy measure of crime risk, and examines the changing spatial distribution of crime risk in the two Northern conurbations of Merseyside and Greater Manchester. The analysis provides an explicit urban focus in order to establish links between the spatial distribution of crime risk and other patterns of deprivation or inequality in the urban environment. Since insurance data is used as a proxy measure of crime risk in the Department of the Environment's Index of Local Conditions, this analysis serves as an interesting basis for both academic and policy discussion. 相似文献

毒品犯罪是全球共同关注的犯罪问题,许多学者从不同的专业领域开展了大量研究。已有文献对毒品犯罪的成因进行分析,由于数据的局限性,较少从微观尺度对毒品犯罪热点的时空分布进行研究。论文以SZ市NH、DM街道内社区为例,基于毒品犯罪案件数据,利用探索性数据分析和时空扫描识别毒品犯罪时空热点分布,结合用地类型、动态人流量等数据定量分析毒品犯罪案件的时空分布影响因素。研究结果如下：① 毒品犯罪主要分布在商业发达地区和城中村地区,且城中村的毒品犯罪时空热点分布的起始时间较商业发达地区更早,影响范围也更大;② 毒品犯罪在不同用地类型分布是不均匀的,其中“住宿旅游娱乐”“商业百货批发零售”“餐饮经营服务品牌”3类用地类型与毒品犯罪具有高度相关性;③ 人流量高热区的面积占比与毒品犯罪的发生有一定的相关性,高热区面积占比大于5%或为0时,能够抑制毒品犯罪的发生;高热区面积占比在0~5%之间,能够促进毒品犯罪的发生。 相似文献

A range of spatial analyses are used in the field of crime mapping, such as kernel density estimation, Ripley's K-function, and spatial autocorrelation, but there is limited use of Voronoi diagrams (VDs). The goal of this article is to contribute to the spatial analysis of crime through the use of VDs. We use four years of commercial robbery data from Campinas, Brazil, and employ several VD techniques: (1) We analyze crime concentrations through the properties of VDs—area and number of vertices—and coverage curve; (2) we introduce a new crime geovisualization with VD in three dimensions; and (3) we apply a network VD technique to crime analysis. The results demonstrate associations between these VD techniques and the ability of the researcher to recognize crime patterns associated with crime concentration, crime along pathways, and the highly regularized distribution of crime in limited areas spatially. 相似文献

警用视频监控的犯罪防控效果及空间差异 ——以苏州市姑苏区为例 总被引：3，自引：2，他引：1
采用双重差分法,对苏州市姑苏区2014~2016年的警情数据进行分析,评估警用治安视频监控的犯罪防控效果。结果表明,视频监控对犯罪具有明显的抑制性作用。在案件类型上,视频监控对盗窃类案件的防控效果较好,但对盗窃电动自行车、盗窃电动车电瓶的防控效果较小。在时间维度上,与节假日相比,对工作日犯罪的抑制效果更好;与晚上相比,对白天犯罪的抑制效果更好。针对通过局部空间自相关分析所获取的重点区域,与警务人员访谈和实地调研后发现,视频监控的犯罪防控效果与周边地理环境、人流密集程度、警务情况等密切相关。 相似文献

街头抢劫者前犯罪经历对其后作案地选择的影响 总被引：1，自引：0，他引：1
作案地选择是犯罪地理学的研究主题。已有的重复作案地选择的研究表明,犯罪者“前案件”作案地选择对他们“后案件”作案地选择具有影响,但以往研究关注的是先前的犯罪时间和地点对其后续作案地选择的影响,仍未检验犯罪者在“前案件”中犯罪经历的具体作用。因此,论文以中国东南沿海ZG市为例,利用街头抢劫者的抓捕数据和混合Logit模型,聚焦探析街头抢劫者先前的个体犯罪经历对他们随后的作案地选择的影响。研究发现：街头抢劫者在“前案件”中的犯罪间隔、犯罪出行和当场被捕等个体犯罪经历对其“后案件”作案地选择具有强烈的影响,即“前后案件”的犯罪间隔越临近、“前案件”犯罪出行距离越短,以及“前案件”未当场被捕,则大大增加了街头抢劫者返回到先前抢劫区域再次犯罪的可能性。并通过警察访谈和结合理论分析,发现“前案件”未当场被捕是由犯罪者当场被捕的恐惧感、警察特殊的干预方式,以及社会凝聚力和犯罪防控的相互作用而形成。研究结论可为警务部门的“事前防控”与“主动处置”提供一定的参考。 相似文献

This article uses an alternative measure of the population at risk, the ambient population (provided by Oak Ridge National Laboratory), in crime rate calculations. It is shown through a variety of statistical analyses at two different scales of aggregation that this alternatively calculated crime rate is not always related to the conventionally calculated crime rate. The implications of this finding are that past theoretical testing and policy formation might have been based on spurious results, showing the importance of remaining current with the developments of geographic information science technologies and data availability when undertaking a spatial analysis of crime. 相似文献

Crime is both a factual and perceptual component of the urban landscape, seemingly both a societal pathology and the consequence of economic disparity between social groups. Crime has a spatial structure that can be revealed by mapping. Urban crime has a spatial multiplier effect that changes the values and perceptions of how people see urban space, and which jeopardizes the quality of life of a city's inhabitants. In this research we examine the question of whether the geography of actual criminal acts is echoed by peoples' perceptions of crime, what might be termed their “spaces of fear”. We ask how the fear of crime is associated with reported urban crime. Urban crime incidents have been increasing in Viçosa, Minas Gerais, Brazil. We assembled crime information about Viçosa from two sources: first, crime as reported to the police and second, crime as perceived by city residents and measured by surveys and interviews. Reported criminal acts reveal a clustered geography, focusing particularly on the Downtown area, where there is a concentration of urban wealth and potential victims are more numerous. Offenses against property were focused on Downtown, while offenses against the person were located mostly in peripheral areas. The widespread feeling of insecurity in the city's neighborhoods, reflecting the fear of becoming a victim of violence and crime, was common throughout the city. Results confirmed the conclusion of past studies showing that the fear of violence and crime are not directly related to increasing numbers of criminal reports. Sites with higher incidence of crimes are not places with higher levels of fear. Rather than being geographically explainable “spaces of fear”, the spatial distribution of the fear of violence and crime appears to be unrelated in Viçosa, and neither is clustered or dispersed in any measurable way. 相似文献

Crime in Urban Post-Disaster Environments: A Methodological Framework from New Orleans 总被引：1，自引：1，他引：0
《Urban geography》2013,34(4):488-510
This paper considers the interrelationship between residential occupancy status, blight, and crime. An analytical frame is provided for a fine-scale analysis that is sufficiently flexible to capture both spatial and temporal dynamism in field-collected data. Unlike other works linking crime to evidence of disorder within neighborhoods, this paper considers this relationship in terms of neighborhoods affected by an external event (natural disaster), which results in more dynamic spatial and temporal patterns as the neighborhood is in a state of flux. As a result, new means of data collection and analysis are required, as any fine-scale relationship is longitudinal as well as cross sectional. The focus here is on the interrelationship of post-disaster residential occupancy, building conditions, and crime incidence for the Holy Cross neighborhood of New Orleans as it recovers from Hurricane Katrina. Results suggest that crime is inversely related to the amount of activity on a recovering street. 相似文献

The fear of crime can significantly reduce the quality of life of individuals, yet little is known about what neighbourhood‐level factors drive feelings of vulnerability in New Zealand. Even less is known about the impact that recorded crime has on individuals' fear in the country. In this study, we examined the neighbourhood‐level factors related to fear of crime in Christchurch, focusing specifically on whether recorded crime in neighbourhoods influences fear. The fear of crime in Christchurch was found to be the greatest in more affluent, ethnically homogenous and residentially stable neighbourhoods, while recorded crime levels were found to be relatively lower in these neighbourhoods. 相似文献

This research analyzes changes in crime rates by city size and determines the extent to which these changes can be explained by socioeconomic variables. More particularly it addresses rates of change in mean crime rates for violent and property crime between 1976–1984 and 1985–1994 for all U. S. cities, then compares results to Ohio cities. It provides a detailed analysis of changing crime rates in 111 Ohio cities with populations between 10,000 and 99,999 inhabitants and attempts to account for crime differentials between these cities employing linear regression and factor analysis. Results indicate that crime is significantly related to poverty and its associated conditions and processes. 相似文献

Neighborhood variations in crime incidence rates are most commonly interpreted through the lens of social disorganization theory, or a "communities and crime" perspective. This approach typically articulates explanation for crime by focusing on the characteristics of communities—a unitary scale most commonly equated with neighborhoods. We argue that this perspective fails to recognize the importance of broader urban geographic contexts, and offer an extension that sees geographically contingent processes functioning at multiple scales simultaneously. We develop this perspective applied to the "spread effects" of public housing on violent crime in surrounding neighborhoods: these spread effects are conditioned by the nature of the urban contexts through which they operate. Specifically, deeply divided and racialized patterns of residential segregation at least partially define the contexts that condition public housing's effect on crime. We examine our perspective using early 1990s block group data for the City of Atlanta and find substantial evidence in support of our perspective. In particular, we find that Techwood Homes, the nation's first federally constructed public housing project, exerted different geographic spread effects in predominantly White than in predominantly Black portions of the city. By failing to recognize the complexity and contingency of public housing's geographic effect on crime in surrounding neighborhoods, previous approaches substantially overestimate crime in White areas, and underestimate crime in Black areas. 相似文献
