In forensic toxicology, opioids are frequently associated with drug abuse or drug-related death cases. An optimal method for use in the identification and quantification of opioids in a complex blood matrix is of paramount importance. Along with the ability to identify and quantitate opioids, this method should be accurate, sensitive, and selective. The application of sample pre-treatment and solid-phase extraction are common to purify and concentrate the target analytes before analyzing with liquid chromatography-tandem mass spectrometry. The purpose of this study was to compare the performance of two standard operating procedures, adopted by the Massachusetts State Police Crime Laboratory Toxicology and the Biomedical Forensic Sciences– Toxicology Laboratory at Boston University School of Medicine, for detecting opioids in blood. A total of eight drugs were analyzed: 6-monoacetylmorphine, codeine, fentanyl, hydrocodone, morphine, norhydrocodone, oxycodone, and oxymorphone. Comparison was performed using the parameters studied as part of method validation, including calibration model, bias, precision, carryover, interferences, ionization suppression/enhancement, and recovery. The results indicated that the method from Massachusetts State Police provided a better performance with between-run precision, interferences from matrix and other commonly encountered drugs, matrix effect at high concentration (250 ng/mL) and matrix recovery. Meanwhile, the method from Biomedical Forensic Sciences showed less bias, within-run precision, and matrix effect at low concentrations. Carryover and internal standard interference were comparable in both standard operating procedures. The calibration models were adjusted by altering the selection of regression model for improved quantification method performance. The volume of solvents, sample matrix, as well as time, were taken into consideration in accessing the overall performance of identification and quantitation. Both procedures were comparable yet the one from Massachusetts State Police was more beneficial in identifying the target analytes with greater sensitivity and selectivity and the one from Biomedical Forensic Sciences was more economical and efficient.

Syftet med studien var att studera polisers uppfattningar kring förhållningssätt till våld i nära relation samt till hur brottstypen hanteras av poliser. I studien genomfördes semistrukturerade intervjuer med sex poliser som i sitt arbete påträffade och hanterade brottstypen. Det huvudsakliga resultatet visade uppfattningar om att det är viktigt att polisen lägger fokus på brottstypen våld i nära relation men också att många poliser har negativa förhållningssätt till brottstypen. Anledningen till de negativa förhållningssätten var att brottstypen ansågs jobbig och mindre spännande eller ”oball” att hantera jämfört med andra brottstyper. Det tycktes även finnas en oförståelse för målsäganden. Majoriteten av intervjudeltagarnas uppfattningar var att poliser hellre tycktes vilja utgå från erfarenhet och rutiner än metodstöd vid hantering av brottstypen. Samtidigt var många av uppfattningen det förhållningssätt poliser har kan inverka på hur de hanterade brottstypen. / The purpose of the study was to examine police perceptions of approaches to family violence and how the type of crime is handled among the police. The study conducted semi-structured interviews with six police officers who in their work encountered and managed the type of crime. The main outcome of the study was that perceptions about the importance of the police focusing on family violence but also opposite perceptions about existing negative attitudes towards the type of crime among police officers. The negative attitudes were explained to depend on that family violence was considered difficult to deal with, less exciting or less “cool” compared with other types of crimes, and that it seemed to be an insufficient understanding for the victim. The majority of the respondents’ perceptions were that policemen seemed more willing to use experience and routines while dealing with family violence than to use some kind of method support. Simultaneously, many perceived that that the attitude of police officers may affect how they handle the crime.

MPD is an entity within the SANDF responsible for maintaining law and order, prevent and combat crime, investigates criminal cases or alleged within the DoD. The role of the MPs has changed drastically over the past years especially after the integration of the non-statutory and statutory forces with all changes in crime growth increased in South Africa and affected the DoD. This led to the MPD shifting from disciplinary crime prevention issues to criminal crime prevention, as the basic mission of the police is to prevent crime and disorder. MPs form part of the police agencies that are within South Africa, the uniqueness of the MPs they operating within the SANDF but they cannot be isolated from the complicated growing crime phenomenon that affects the whole South African community. As crime prevention is the catchphrase for all the police agencies and government departments, it is imperative for the MPs to align its crime prevention to the modern policing. This study gives a comprehensive explanation of what crime prevention is, from the literature reviewed relevant to the study, with the aim to critically analyse the role of the MPs in crime prevention within the military proclaimed environment. The researcher collected data in the form of unstructured interviews, documents and literature. Collected data was transcribed; larger text was broken into smaller segments, coded and then selected into themes. Participants had different views of the understanding of the meaning of crime prevention and different comprehension of the MPs crime prevention guideline and procedures. This analysis was done in order to determine the level of understanding of the role of the MPs, in crime prevention within the military proclaimed environment and how MPs can be effective and efficient within this environment. / Police Practice / M.

In dem Bericht werden die Daten der ersten Erhebungswelle der Panelstudie zur Wahrnehmung von Kriminalität und Straftäter:innen (PaWaKS) analyisert. Dazu wurde eine deutschlandweite repräsentative Stichprobe von 5000 erwachsenen Personen befragt. Die Ergebnisse in Kürze: Diejenigen Befragten, die Kontakt zu Polizei und Justiz bzw. zu Straftäter:innen hatten, beschrieben diesen Kontakt als überwiegend positiv. Junge Menschen sowie Menschen mit Migrationshintergrund bewerteten den Kontakt mit Justiz/Polizei etwas weniger positiv als Menschen aus anderen Altersgruppen bzw. ohne Migrationshintergrund. Wie von der Kontakthypothese angenommen, ging positiver Kontakt zu Polizei und Justiz mit positiven Einstellungen gegenüber Polizei und Justiz einher, ebenso mit höherem Vertrauen in diese Institutionen. Gleichzeitig zeigte sich aber ein leicht negativer Zusammenhang zu Einstellungen gegenüber Straftäter:innen. Positiver Kontakt mit Straftäter:innen hing mit positiveren Einstellungen gegenüber Straftäter:innen zusammen, aber nicht mit Einstellungen zu und Vertrauen in Polizei und Justiz. Dieser Befund spricht gegen negative Nebeneffekte von Kontakt mit Straftäter:innen. Positive Kontakterfahrungen können zur Verbesserung der Beziehungen zu und Wahrnehmung von Polizei und Justiz sowie Straftäter:innen beitragen und so größeres Vertrauen in die Institutionen und eine verbesserte Reintegration von Straftäter:innen in die Gesellschaft ermöglichen.:Inhaltsverzeichnis Das Wichtigste in Kürze 4 1 Einleitung 5 1.1 Intergruppenkontakt 6 1.2 Intergruppenkontakt mit Polizei und Justiz 7 1.3 Intergruppenkontakt mit Straftäter:innen 8 2 Methode 9 2.1 Vorgehensweise 9 2.2 Erhebungsinstrumente 9 2.3 Beschreibung der Stichprobe 10 3 Interindividuelle Unterschiede 11 3.1 Kontakt mit Vertreter:innen des Justizsystems 11 3.2 Kontakt mit Straftäter:innen 16 4 Zusammenhangsanalysen 20 4.1 Einstellungen gegenüber Polizei, Justiz und Straftäter:innen 21 4.2 Kriminalitätsfurcht 22 4.3 Vertrauen in Polizei und Justiz 23 4.4 Attribution von Kriminalität und Punitivität 23 5 Fazit 25 Glossar 27 Literaturverzeichnis 29 Impressum 34
