Colliding intervention in the spatial management of street-based injecting and drug-related litter within settings of public convenience (UK)

This paper considers the structural production and amplification of tensions surrounding the issue of street-based injecting drug use and drug-related litter (injecting paraphernalia) discarded in public settings. These tensions, it is argued, is a consequence of colliding intervention (policy and practice) brought about by conflicting connections between national/local drug strategy and micro-level forms of governance regarding the spatial management of public space. These colliding interventions have negative consequences upon harm reduction and the formation of enabling environments. The paper draws upon data obtained from a five-year (multi-site) ethnographic study of street-based injecting conducted throughout the south of England during 2006–2011.

时间价格指数和空间价格指数的比较与协调

价格指数在经济政策尤其是价格政策制定中发挥着重要作用。从时空维度上看,价格指数一般可分为时间价格指数和空间价格指数,二者都属于价格统计的范畴,在编制要素、编制流程、组织管理模式、加权处理方式、质量调整方法等方面具有一致性。但是,时间价格指数和空间价格指数也存在显著的差异性,主要体现在理论内涵、指数性质、测度目标、计算公式、规格品价格调查范围、权重数据来源、规格品选择方案和对数据的要求等方面。推动时间价格指数与空间价格指数的协调,有助于建立一致、统一的价格统计体系,形成反映地区价格水平及变动的完整图谱。为此,实践上应积极探索ICP与CPI统计体系的整合,增加二者在居民消费品基本支出分类上的直接匹配度。     

Spatial analysis of violent crimes in Metro Manila,Philippines

Spatial patterns of murder and physical injury in Metro Manila, Philippines were visualised through conditional choropleth maps. Relationship of both crime rates with some demographic variables were investigated while accounting for possible spatial autocorrelation using spatial lag models. Results show that both crime rates tend to cluster in the northern cities of Metro Manila. Furthermore, significant spatial lag coefficients were found only for physical injury rates, with values ranging from 0.49 to 0.62, signifying a positive city-level spatial dependence of physical injury rates in Metro Manila. Moreover, some demographic covariates, such as population density, percentage of young males, education, marriage, and immigration were found to be associated with both crime rates. These results could serve as useful indicators of crime incidence; thus it is recommended that crime monitoring systems include them to aid in resource allocation and program planning for better crime prevention and security management.     

Crime-Reduction Effects of Open-street CCTV: Conditionality Considerations

This study addresses the conditional nature of the effectiveness of open-street CCTV (closed circuit television) by examining the differences in the effects (1) between daytime and nighttime crime, (2) between weekday and weekend crime, (3) across specific-crime offenses, and (4) depending on CCTV site characteristics, including location type (e.g. downtown, business district, school/university, or residential area) and the site’s base rate of crime. This study used HLM (hierarchical linear modeling) with 84 repeated measures across 34 camera locations in Cincinnati, Ohio, while also accounting for overlapping camera areas. Overall, the findings provided minimal evidence of the effectiveness of CCTV in reducing crime, though some types of crime were reduced in residential areas especially, and effectiveness was clearly interdependent with an area’s base rate of crime. Finally, WDQ analyses showed that diffusion of benefits occurred much more often than displacement in cases where there was a crime reduction, post-CCTV.     

Global Energy Governance: Trade,Infrastructure, and the Diffusion of International Organizations

Why do states choose to join and form international governmental organizations (IGOs) that regulate energy policy? In this article we make three specific contributions to the literature on international cooperation and diffusion. First, we show that countries form and join energy IGOs in response to memberships previously gained by direct competitors among oil and gas producers and consumers. Moreover, we demonstrate that energy IGOs diffuse among countries that share oil and gas pipelines. Finally, we provide evidence that the institutional design of established energy IGOs impacts the development of their membership network. To test these hypotheses, we rely on original data on oil and gas pipelines and the design of energy IGOs as well as on a newly compiled dataset that includes 152 countries and covers 38 years (1970–2007). We employ both network analysis and spatial econometrics.     

TARGET CHOICE DURING EXTREME EVENTS: A DISCRETE SPATIAL CHOICE MODEL OF THE 2011 LONDON RIOTS

Riots are extreme events, and much of the early research on rioting suggested that the decision making of rioters was far from rational and could only be understood from the perspective of a collective mind. In the current study, we derive and test a set of expectations regarding rioter spatial decision making developed from theories originally intended to explain patterns of urban crime when law and order prevail—crime pattern and social disorganization theory—and consider theories of collective behavior and contagion. To do this, we use data for all riot‐related incidents that occurred in London in August 2011 that were detected by the police. Unlike most studies of victimization, we use a random utility model to examine simultaneously how the features of the destinations selected by rioters, the origins of their journeys, and the characteristics of the offenders influence offender spatial decision making. The results demonstrate that rioter target choices were far from random and provide support for all three types of theory, but for crime pattern theory in particular. For example, rioters were more likely to engage in the disorder close to their home location and to select areas that contained routine activity nodes and transport hubs, and they were less likely to cross the Thames River. In terms of contagion, rioters were found to be more likely to target areas that had experienced rioting in the previous 24 hours. From a policy perspective, the findings provide insight into the types of areas that may be most vulnerable during riots and why this is the case, and when particular areas are likely to be at an elevated risk of this type of disorder.     

EGOHOODS AS WAVES WASHING ACROSS THE CITY: A NEW MEASURE OF “NEIGHBORHOODS”

Defining “neighborhoods” is a bedeviling challenge faced by all studies of neighborhood effects and ecological models of social processes. Although scholars frequently lament the inadequacies of the various existing definitions of “neighborhood,” we argue that previous strategies relying on nonoverlapping boundaries such as block groups and tracts are fundamentally flawed. The approach taken here instead builds on insights of the mental mapping literature, the social networks literature, the daily activities pattern literature, and the travel to crime literature to propose a new definition of neighborhoods: egohoods. These egohoods are conceptualized as waves washing across the surface of cities, as opposed to independent units with nonoverlapping boundaries. This approach is illustrated using crime data from nine cities: Buffalo, Chicago, Cincinnati, Cleveland, Dallas, Los Angeles, Sacramento, St. Louis, and Tucson. The results show that measures aggregated to our egohoods explain more of the variation in crime across the social environment than do models with measures aggregated to block groups or tracts. The results also suggest that measuring inequality in egohoods provides dramatically stronger positive effects on crime rates than when using the nonoverlapping boundary approach, highlighting the important new insights that can be obtained by using our egohood approach.     

Mapping Urban Revitalization: Using GIS Spatial Analysis to Evaluate a New Housing Policy

This longitudinal, multimethod study uses geographical information system (GIS) software to evaluate the community-wide impact of a neighborhood revitalization project. Unsystematic visual examination and analysis of GIS maps are offered as a complementary tool to quantitative analysis and one that is much more compelling, meaningful, and effective in presentation to community and nonscientific professional audiences. The centerpiece of the intervention was the development of a new, middle-class housing subdivision in an area that was declining physically and economically. This represents three major urban/housing policy directions: (1) the emphasis on home ownership for working-class families, (2) the deconcentration of poverty through development of mixed-income neighborhoods, and (3) the clean up and redevelopment of contaminated, former industrial brownfields. Resident survey responses, objective environmental assessment observations, and building permit data were collected, geocoded at the address level, and aggregated to the block level on 60 street blocks in the older neighborhoods surrounding the new housing in two waves: during site clearing and housing construction (Time 1: 1993–95) and three years post-completion (Time 2: 1998–99). Variables mapped include (a) Time 1–2 change in self-reported home repairs and improvements, (b) change in the assessed physical condition of yards and exteriors of 925 individual residential properties, (c) change in residents' home pride, and (d) a city archive of building permits at Time 2. Physical conditions improved overall in the neighborhood, but spatial analysis of the maps suggest that the spillover effects, if any, of the new housing were geographically limited and included unintended negative psychological consequences. Results argue for greater use of GIS and the street block level in community research and of psychological and behavioral variables in planning research and decisions.     

Integrating Policies,Plans and Programmes in Local Government: An Exploration from a Spatial Planning Perspective

Local government bodies are increasingly attempting to integrate different functions and departments in the production of policies, plans and programmes. Despite this interest, a general lack of conceptualisation around integration currently exists, presenting difficulties for local government practitioners to pursue such integration. This article reports findings of an ESRC PhD case study into integration in local government, and presents a conceptualisation which seeks to resolve these outstanding issues surrounding integration. These findings are particularly apt given the ongoing changes to local government in England.
