A flow‐injection analysis tandem mass spectrometry (FIA MSMS) method was developed for rapid quantitative analysis of 10 different inorganic and organic explosives. Performance is optimized by tailoring the ionization method (APCI/ESI), de‐clustering potentials, and collision energies for each specific analyte. In doing so, a single instrument can be used to detect urea nitrate, potassium chlorate, 2,4,6‐trinitrotoluene, 2,4,6‐trinitrophenylmethylnitramine, triacetone triperoxide, hexamethylene triperoxide diamine, pentaerythritol tetranitrate, 1,3,5‐trinitroperhydro‐1,3,5‐triazine, nitroglycerin, and octohy‐dro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine with sensitivities all in the picogram per milliliter range. In conclusion, FIA APCI/ESI MSMS is a fast (<1 min/sample), sensitive (~pg/mL LOQ), and precise (intraday RSD < 10%) method for trace explosive detection that can play an important role in criminal and attributional forensics, counterterrorism, and environmental protection areas, and has the potential to augment or replace several of the existing explosive detection methods. 相似文献

Create an overview of characteristics of patients in long-term forensic psychiatric care (LFPC) with a higher length of stay (LOS) care compared to patients in regular forensic psychiatric care (RFPC) with a shorter LOS. Data were collected from 139 patient records. This study examined whether patients in LFPC differ from patients in RFPC on sociodemographic data, legal data and clinical data and whether those characteristics are able to predict LOS. Patients in LFPC were more often born in a Dutch Caribbean country, less often had a substance abuse disorder, were more often emotionally neglected during childhood, had a higher HCR-20 risk item score, a higher security needs score, a higher (less successful) recovery score, were more often recidivist and had absconded more often than RFPC patients. Certain characteristics were able to distinguish the longer LOS group which might be useful to establish sequel services and enhance treatment efficiency. 相似文献

Modelling the relationship between counter‐knowledge and open‐mindedness for policy development 下载免费PDF全文
Pedro‐José Martínez‐Ortiz Sandra Moffett Juan‐Gabriel Cegarra‐Navarro Fernando A. López Hernández 《Journal of Public Affairs (14723891)》2017,17(3)
Counter‐knowledge refers to flaws in citizens' mental models arising from utilization of rumours, inappropriate knowledge structures, outdated routines or procedures. When counter‐knowledge is applied to civil servants, it may result in problems of efficiency, equity and motivation. This paper examines the relationship between counter‐knowledge and open‐mindedness to model a framework for improving city marketing and policy development. This study tested two measurement models. While the theoretical model represents the effect of counter‐knowledge on city marketing and that the latter has a negative effect on open‐mindedness, the alternative model involves that counter‐knowledge has a positive indirect impact on open‐mindedness. These relationships are examined through an empirical investigation of 203 Spanish city halls. The results show a potential positive indirect effect of counter‐knowledge on open‐mindedness through city marketing programmes. This paper clarifies the existing literature, which tries to contribute to the discussion of city marketing, and helps us to obtain meaning out of the relationship between counter‐knowledge, city marketing and open‐mindedness.

This study examined adolescents' ideas about girls' and boys' use and experience of physical and psychological abuse in heterosexual dating relationships. Canadian high school students who were enrolled in Grades 9 and 11 took part in single-gender focus groups. Eight themes emerged from the analysis. The themes highlight the importance teenagers place on context for defining specific behaviors as abusive. They also underscore gender differences in the criteria adolescents use to make these judgments, in the forms of abusive behavior teenagers typically use in a dating relationship, and in the reasons for youths' declining use of physical abuse and increasing use of psychological abuse. These views have important implications for future research and for programs targeting adolescent dating violence. 相似文献

This article critically examines an HIV/AIDS development and research project in Mwanza, Tanzania. A group of women produce a type of probiotic yoghurt that has provided evidence of lowering the incidence of HIV infection. The yoghurt is consumed by the women, their family members, and local citizens living with HIV/AIDS; surplus is sold within the community. While the project's multi-partner, multi-disciplinary composition allows for varied expertise and insights, it also requires open and collaborative dialogue. This article discusses the project's challenges, positive outcomes, and some of the socio-cultural issues that need to be addressed if it expands in size and/or scope. 相似文献
