社会治安情报监控浅析

社会治安情报监控是开放性社会环境下，公安机关全面、准确、及时掌握社会动态和治安状况，预防、发现、精确打击违法犯罪活动，维护社会治安稳定的重要手段。它通过收集和分析有关重点人员、重要场所等方面的情报信息，实现对监控对象自动发现、自动预警、轨迹跟踪、动态管控的目标。其工作流程，既是对监控对象实施“排查-监视-处置”的过程，也是情报信息“规划-收集-研判-反馈”的循环过程。吸毒人员动态管控是社会治安情报监控的具体实例，做好吸毒人员信息的采集、审核、维护及应用，是吸毒人员动态管控机制正常运行的根本保障。     

Separation and Detection of Smokeless Powder Additives by Ultra Performance Liquid Chromatography with Tandem Mass Spectrometry (UPLC/MS/MS),

A reversed phase gradient ultra performance liquid chromatography tandem mass spectrometry (UPLC/MS/MS) method has been developed for the analysis of smokeless powders. A total of 20 different components were separated by UPLC and detected by MS/MS in multiple reaction monitoring (MRM) mode. These compounds included diphenylamines, centralites, nitrotoluenes, nitroglycerin, and various phthalates. Simultaneous positive and negative electrospray ionization (ESI) was used along with negative atmospheric pressure chemical ionization (APCI) to detect all compounds in a single analysis. Analysis times were under 8 min with a gradient of 10–73% organic at a flow rate of 0.500 mL/min. With this method, ultraviolet and MRM limits of detection ranging from 0.08 to 2.6 ng and 0.4–64 ng injected were achieved. Commercially available smokeless powders were also extracted with methylene chloride and characterized using the developed UPLC/MS/MS method. The procedure permits the determination of compositional differences between different brands as well as lot‐to‐lot variations.     

我国监听制度立法不足及其完善

监听作为技术侦查手段之一,为弥补传统侦查手段不足,有效打击犯罪发挥了巨大的作用。但由于监听本身固有的隐密性、强制性,加之我国有关监听的专门法律规范几近空白,使得这一有力武器在打击犯罪的同时又极易造成相对人合法权益的侵犯。因此,我国应当借鉴国外立法及经验,对监听进行立法,使之有效运转,以达到保障公民权利和打击犯罪两种价值的平衡。     

Parenting by Cell Phone: Parental Monitoring of Adolescents and Family Relations

Cellular phones provide a means for parents to monitor and request information about whereabouts, associates, and current activities from adolescents. Simultaneously, adolescents can communicate with parents to inform them of activities and to solicit support or they can also choose to nondisclose. The frequency, duration, and nature of calls may relate to parents’ and to adolescents’ perceptions of truthfulness and family relationships. 196 dyads (13% father–son, 11% father–daughter, 30% mother–son, and 46% mother–daughter) completed a questionnaire indicating cell phone use, their truthfulness of activities, the nature of their calls to one another, and family relationships. The parents were, on average, 45.38 years old (SD = 6.35) and were 83% Euroamerican, 9% Asian American, 3% Latino, 3% African American, 2% Mixed ethnicity, and 1% American Indian. The adolescents were, on average, 16.25 years old (SD = 1.17) and were 77% Euroamerican, 9% Asian American, 4% Latino, 3% African American, 8% Mixed ethnicity, and .5% American Indian. Correlational analyses revealed that parents who called more frequently reported less truthfulness when speaking to their adolescents via cell phone. Greater frequency in parental calls also was associated with less adolescent-reported truthfulness. From multiple regression analyses, for parents, calls when upset were associated with less parental knowledge and poorer family relations. For adolescents, the same was true; however, adolescents who made calls seeking social support and to ask and confer with parents reported greater perceived parental knowledge and better family relationships.

The (im)plausibility of racism in Europe: policy frameworks on discrimination and integration

ABSTRACT

Rodríguez Maeso and Araújo analyse the reproduction of a dominant understanding of racism in policy discourses of integration and discrimination used by monitoring agencies in Portuguese and European Union (EU) institutional contexts. More specifically, they question the political concern over racism and discrimination vis-à-vis the idea of Europe ‘becoming increasingly diverse’ and the need to gather ‘evidence’ of discrimination. To that end, they examine periodic reports issued by EU monitoring agencies since the 1990s—paying specific attention to reporting on school segregation of Roma pupils in Portugal—and national integration policies and initiatives that, since the 2000s, have targeted mainly Roma and black families and youth. They argue that the dominant discourse of integration and cultural diversity conceives of racism as external to European political culture, and as a ‘factor’ of the ‘conflictive nature’ of social interactions in ethnoracially heterogeneous settings. This paves the way for calls for the ‘strengthening of social cohesion’—on the assumption that policy initiatives need to act on the ‘characteristics’ of so-called ‘vulnerable’ populations—whereas institutional arrangements and everyday practices remain unchallenged.     

Α Simple Method for the Determination of Lacosamide in Blood by GC-MS

Lacosamide is a functionalized amino acid with antiepileptic function. Therapeutic drug monitoring (TDM) in patients for lacosamide is critical as it allows clinicians to control epileptic seizures. A single liquid–liquid extraction step was applied for the extraction of lacosamide from whole blood samples which were thereafter analyzed by GC-MS. Optimum extraction conditions were selected on the basis of experiments with various solvents at different pHs, indicating ethyl acetate at pH 12 as the most efficient parameters for the extraction of lacosamide. Method exhibited linearity from 2 to 100 μg/mL with R² = 0.998. Accuracy and precision were evaluated at three concentrations and found to be within acceptable limits. LOD and LOQ were determined at 0.1 and 0.5 μg/mL, respectively. Lacosamide was found to be stable at storage conditions. The developed method was applied successfully in clinical samples and postmortem blood sample from an overdose case.

Victimization and Relational Aggression in Adolescent Romantic Relationships: The Influence of Parental and Peer Behaviors, and Individual Adjustment

Consistent with the view that adolescent relationships are established in the context of important characteristics of their social networks, we examined the effects of adolescents’ experiences of parenting (psychological control and positive monitoring) and of peer aggression and victimization, on their self reports of dating victimization and aggression. We also examined the effects of individual differences in emotional and behavioral problems. We used questionnaire data from a population-based sample of youth 12–18 years old who were in dating relationships (n = 149). Parental monitoring emerged as a protective factor in reducing both dating victimization and relational aggression. Our findings also point to a significant transfer of aggression in peer relationships to relational aggression in dating relationships.

论我国沿边开放城市的区域职能缺失

我国的沿边开放城市(镇),面临着加入WTO、区域经济一体化、西部大开发和东北老工业基地振兴的新形势,表现出以增长极职能和跨国影响职能为主要内容的区域职能缺失。沿边开放城市增长极职能缺失的主要原因是:规模过小、城市体系发育不良、产业链短、交通基础设施不完善;国际影响职能缺失的原因在于:城市在跨境城市体系中能级较低、经济结构单一、支持腹地缺乏、区域经济一体化程度低。为此,策略性调整势在必行,要完成从沿边开放城市到边境地区中心城市的转变,需要实现边境城市的规模扩张、功能发展和城市体系布局合理化。
