本文以地区而不是传统上占主导地位的国际体系作为理解和解释国际政治与国家行为的概念基础,构建起一个地区与国家相互塑造的分析框架。透过这个框架,可以解释:地区对国家的地位与权力、认同与观念、政策与行为的塑造;与此同时,国家的相对权力及其变化、观念和政策及其转变还对地区体系和制度秩序的形成产生一定影响。从动态的角度来看,地区与融入其中的国家处于相互塑造的过程中。彼此从对方那里吸取不同的元素,并以不同的方式相互进行重塑和改造。地区与国家之间存在基于过程选择的互动关系,它为理解改革开放以来中国外交政策的调整以及与亚太周边地区变化中的新关系提供了理论视角。 相似文献

作为地区研究层次的两个变量,地区主义与地区秩序之间有着不可分割的内在联系。地区主义的产生与发展,很大程度上源于国家的自愿选择与共识,这种运行方式维护了地区所有成员的利益,从本质上保证了地区秩序的有效性、合法性和持久性。从地区发展的实践来看,构建地区秩序的模式主要有外源强制型、内源强制型、外源合作型和内源合作型四种。地区主义的发展改变了地区各政治实体之间的互动关系,通过价值观念与地区认同、地区制度以及地区主义的政治经济影响等因素促使地区秩序逐步从外源强制型向内源合作型演进。 相似文献

Since the 2016 Brexit referendum a series of crises has gripped Northern Ireland's politics. This has had a destabilising effect across society, which has arguably been felt most acutely by political unionism. The Belfast/Good Friday Agreement (B/GFA) of 1998 created a series of institutions to deal with political conflict in Northern Ireland, manage cross-border cooperation and normalise relations between the UK and Ireland. However, many aspects of it have been sparingly and ineffectually deployed, most notably the second and third strands dealing with north/south and east/west relations respectively. In this article, the authors argue that regular use of the institutional arrangements created by the Agreement would help to deal with the challenges currently facing Northern Ireland and help address unionist anxieties over the Protocol. Use of the North-South Ministerial Council (NSMC), the British Irish Council (BIC) and the British-Irish Intergovernmental Conference (BIIGC) should be prioritised. The unresolved issues arising from Brexit require a recommitment to the intergovernmental logic at the heart of the 1998 Agreement, despite the obstacles. 相似文献

Carbon‐based materials are often used as matrices for matrix‐assisted laser desorption/ionization mass spectrometry (MALDI‐MS) and its imaging (MALDI‐MSI). However, researchers have refrained from using carbon‐based fingerprint powder (CFP) as a matrix due to high background and contamination. In this work, the compatibility of CFP is reevaluated with MALDI‐MSI using a high‐resolution mass spectrometer (HRMS) and compared to traditional organic matrices. Relevant fingerprint compounds were easily distinguished from carbon cluster peaks when using HRMS. For fair comparison, half of a fingerprint was dusted with CFP while the other half was dusted with traditional organic matrices. All compounds studied had comparable, or higher, signal‐to‐noise (S/N) ratios when CFP was used as the matrix. Additionally, chemical image qualities closely followed the trend of S/N ratios. CFP proved to be an effective one‐step development and matrix application technique for MALDI‐MSI of latent fingerprints, when carbon cluster peaks are well separated by a HRMS. 相似文献

In several medico‐legal cases, bone samples analysis may provide the only source of toxicological information. This case study reports the analysis of a human bone specimen, belonging to a 46‐year‐old man, found 3 months after his death due to cervical–thoracic injuries in a motorcycle accident. Bone specimen was the only available material for toxicological analysis, among few skull hair and rotten skin. Analysis was performed by a newly developed and validated ultra‐high‐pressure liquid chromatography–mass spectrometry/mass spectrometry (UHPLC‐MS/MS) method, following simple and efficient sample pretreatment. The results were in accordance with the man's medical record: Alprazolam and zolpidem were found at 2.2 and 5.4 ng/g of bone, respectively. Both these drugs were prescribed to the deceased. 相似文献

We test structural hypotheses regarding police-caused homicides of minorities. Past research has tested minority threat and community violence hypotheses. The former maintains that relatively large minority populations are subjectively perceived as threats and experience a higher incidence of police-caused homicide than whites do, the latter that higher rates of violent crime among minorities create objective threats that explain these disparities. That research has largely ignored some important issues, including: alternative specifications of the minority threat hypothesis; the place hypothesis, which maintains highly segregated minority populations are perceived as especially threatening by police; and police-caused homicide in the Hispanic population. Using data for large U.S. cities, we conducted total-incidence and group-specific analyses to address these issues. A curvilinear minority threat hypothesis was supported by the Hispanic group-specific findings, whereas the place hypothesis found strong support in both total and group-specific analyses. These results provide new insights into patterns of police-caused homicide. 相似文献

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. 相似文献

The present study aimed at providing data to assess the secondary transfer of organic gunshot residues (OGSR). Three scenarios were evaluated in controlled conditions, namely displacing a firearm from point A to point B, a simple handshake and an arrest involving handcuffing on the ground. Specimens were collected from the firearm, the hands of the shooter and the non-shooter undergoing the secondary transfer in order to compare the amounts detected.Secondary transfer was observed for the three scenarios, but to a different extent. It was found that displacing a firearm resulted in secondary transfer in <50% of the experiments. The firearm also had an influence, as contrary to the pistol, no secondary OGSR were detected using the revolver. Shaking the hand of the shooter also transferred OGSR to the non-shooter's hand. In that case, the amount of OGSR was generally higher on the shooter than on the non-shooter. Finally, the largest secondary transfer was observed after the arrest with handcuffing with positive results in all cases using the pistol. In that scenario, the amounts on the shooter and the non-shooter were in the same range.This study highlights that the secondary transfer must be taken into account in the interpretation of OGSR. Indeed, an individual's hands might be contaminated by handling a firearm or having physical contact with a shooter. 相似文献

STREET NETWORK STRUCTURE AND CRIME RISK: AN AGENT‐BASED INVESTIGATION OF THE ENCOUNTER AND ENCLOSURE HYPOTHESES

Street networks shape day‐to‐day activities in complex ways, dictating where, when, and in what contexts potential victims, offenders, and crime preventers interact with one another. Identifying generalizable principles of such influence offers considerable utility to theorists, policy makers, and practitioners. Unfortunately, key difficulties associated with the observation of these interactions, and control of the settings within which they take place, limit traditional empirical approaches that aim to uncover mechanisms linking street network structure with crime risk. By drawing on parallel advances in the formal analyses of street networks and the computational modeling of crime events interactions, we present a theoretically informed and empirically validated agent‐based model of residential burglary that permits investigation of the relationship between street network structure and crime commission and prevention through guardianship. Through the use of this model, we explore the validity of competing theoretical accounts of street network permeability and crime risk—the encounter (eyes on the street) and enclosure (defensible space) hypotheses. The results of our analyses provide support for both hypotheses, but in doing so, they reveal that the relationship between street network permeability and crime is likely nonlinear. We discuss the ramifications of these findings for both criminological theory and crime prevention practice. 相似文献
