合理行使紧追权 维护中国海洋权益

紧追权是国际法赋予沿海国有效行使管辖权的一项重要权利。正确、合理行使紧追权等国际法权利,对于强化和规范海上执法、维护中国海洋权益、妥善解决海洋执法纠纷,具有重要的现实意义。从如何行使紧追权入手,由点到面,探讨国际法在中国海洋执法过程中的应用问题以及中国海洋执法队伍的建设问题。     

Could Innovations in Policing have Contributed to the New York City Crime Drop even in a Period of Declining Police Strength?: The Case of Stop,Question and Frisk as a Hot Spots Policing Strategy

Available data make it impossible to reach strong conclusions about the role of policing in the New York crime decline. Instead, we examine whether innovations implemented in New York fit with what is known about effective policing strategies. Our main analysis focuses on how the New York City Police Department (NYPD) could have continued to contribute to the crime drop over the last decade when the number of police declined significantly. We examine geographic data on crime and stop, question and frisks (SQFs) to show that SQFs are concentrated at crime hot spots. We also show that the NYPD increased these specific hot spots policing strategies despite declining numbers. In our discussion, we speculate on whether this “doing more with less” could be an explanation for the continued crime drop in New York, noting the limitations of drawing conclusions from existing data. We also raise concerns about possible backfire effects of SQF hot spots approaches.     

Location,location, location: Interdistrict and intercircuit variation in sentencing outcomes for federal drug-trafficking offenses

Research on sentencing has made clear that factors beyond case and offenders' attributes influence court decisions. Environmental and procedural characteristics also significantly affect the sentences of criminal courts. Yet, while state-level studies regularly control for such factors, most research on modern federal determinate sentencing has neglected jurisdictional attributes and variation as sources of extralegal sentence disparity. Using the organizational context and social worlds theoretical perspectives with a multilevel analytical approach, this study assessed how district and circuit of adjudication affect case-level lengths of sentences for federal drug-trafficking offenses, finding that both significantly affect sentencing outcomes and their predictors.

Spatio-Temporal Interaction of Urban Crime

Over the past decade, a renewed interest in the analysis of crime hot-spots has emerged in the social and behavioral sciences. Spurred by improvements in computing power, data visualization and geographic information systems, numerous innovative approaches have materialized for identifying areas of elevated crime in urban environments. Unfortunately, many hot-spot analysis techniques treat the spatial and temporal aspects of crime as distinct entities, thus ignoring the necessary interaction of space and time to produce criminal opportunities. The purpose of this paper is to explore the utility of statistical measures for identifying and comparing the spatio-temporal footprints of robbery, burglary and assault. Functional and visual comparisons for spatio-temporal clusters are analyzed across a range of space–time values using a comprehensive database of crime events for Cincinnati, Ohio. Empirical results suggest that robbery, burglary and assault have dramatically different spatio-temporal signatures.

南海打击海盗的国际合作法律机制研究

维护南海尤其是马六甲海峡的海上航道安全,对全球国际贸易运输具有十分重要的意义,中国的贸易和石油安全很大程度上取决于南海航道的安全。南海航道并不太平,海盗袭击在南海航道上时有发生,海上恐怖主义也有可能将其触手伸向马六甲海峡上行驶的过往船舶,如何维护南海航道的安全对周边国家和世界贸易具有特殊的意义。在打击海盗等破坏航运安全犯罪活动中,国际法律机制还存在诸多不足,海盗罪在联合国海洋法公约中规定的范围过于狭窄,一些周边国家还没有签署《制止危及海上航行安全非法行为公约》,《亚洲地区反海盗及武装劫船合作协定》的合作机制也有进一步深化的必要。在未来的法律机制创建中,有必要进一步扩大海盗罪的范围,破除联合护航中的法律障碍,方便各国行使紧追权,并加强船舶追回的合作,以维护中国和周边国家的航运安全。     

Explaining Dosage Diffusion During Hot Spot Patrols: An Application of Optimal Foraging Theory to Police Officer Behavior

Drawing from the concepts of optimal foraging theory, this paper presents and tests the assumptions of a foraging theory of police behavior during hot spots patrols. The theory explains why, over time, officers involved in hot spots policing interventions would leave the hot spots they are assigned to police and begin working within other locations. We test what factors influence the amounts of activity that officers undertake outside of their assigned hot spots and at nearby streets using data gathered as part of the Philadelphia Foot Patrol Experiment. Officers performed more activity outside of their beats as the experiment progressed. Several theoretically relevant variables predict the level of activity that officers perform outside their beats, including the size of the target area and the amounts of crime occurring within and outside of the target area. “Dosage diffusion” might be one reason why hot spot interventions have diminishing effects over time. From an optimal foraging theory perspective, hot spots requiring police officers to constrain their actions to pre-defined areas can be perceived as counter-intuitive by the officers, especially over extended periods of time. The results of this study support the suggestion that hot spots patrols should be short-term and randomly rotated across hot spots.

Houston Enhanced Action Patrol: Examining the Effects of Differential Deployment Lengths with a Switched Replication Design

Studies have tested variations of concentrated patrol combined with intense field interrogations, broken windows enforcement, Compstat accountability, and problem-oriented approaches. Although a majority of findings support the efficacy of concentrated patrol, a substantial number do not. Questions remain regarding six variables: dimension, dosage, duration, displacement, diffusion, and denouement. This study tested differential deployment lengths of geographically concentrated, proactive patrol for an additional 80?h per week in 13 high crime beats in Houston, TX. The original purpose was to identify optimal lengths of deployment periods. The study used a switched replication design with repeated treatments over deployment periods ranging from 4 to 12 weeks. Meaningful reductions in suppressible street crime occurred in only 2 of the 13 beats. The two beats were among the smallest, had among the highest crime rates, and received the highest dosage of concentrated patrol.
