Einleitung: Berufsbildungs‐ und Hochschulpolitik in der Schweiz, Österreich und Deutschland

Politikwissenschaftliche Bildungsforschung hat bislang vier Schwerpunkte: Vergleichende Policy‐Analyse, Prozesse der Internationalisierung und Europäisierung, Arbeiten der vergleichenden politischen Ökonomie sowie Studien zu den Effekten von Bildungsinstitutionen und ‐politiken. Auf der Grundlage einer dichten Analyse der gegenwärtigen Transformation und Reform von Bildungs‐ und Ausbildungssystemen in der Schweiz, Österreich und Deutschland ergänzen die Artikel‐ und Forumsbeiträge dieses Sonderheftes diese Perspektiven um drei spezifische Punkte, die in der zukünftigen Forschung zum Wandel von Bildungssystemen vertieft werden sollten: erstens die Untersuchung der Wechselwirkungen zwischen Bildungspolitik und der föderalen Entscheidungsarena, zweitens die Analyse des Einflusses von Machtverteilung und der Dynamik politischer Koalitionen auf Reformen und drittens die Unterscheidung zwischen Reformpolitik und Prozessen des institutionellen Wandels.     

推动习近平新时代中国特色社会主义思想“往心里走”的成效、问题与对策——基于两次问卷调查的数据分析

当前推动习近平新时代中国特色社会主义思想“往心里走”的举措具有整体性、全面性的特点。基于项目组开展的一系列调研,从基本认知、情感认同、行为考察等三个层面得出目前“往心里走”取得一定成效。但同时,在教育培训、自主学习、主动践行、社会宣传和评价体系等方面也面临诸多问题。应以体制机制创新推动教、学、用、宣的联动和集成;发挥领导干部、行业精英、教师群体等关键人群的带动、示范、引导作用;进一步发挥党校(行政学院)、社会主义学院、干部学院等主阵地在基层教育培训中的重要作用;坚持以引导性原则、实用性原则、层次性原则构建“往心里走”的评价体系。     

Background levels of body fluids and DNA on the shaft of the penis and associated underpants in the absence of sexual activity

This study examines the background of blood, saliva, semen and autosomal DNA on penile swabs and underpants from males in the absence of recent sexual activity. Based on the data collected by the AFSP Body Fluid Forum, the results of this study show that; there is a very low expectation of detecting blood on penile swabs and male underpants; a low expectation of detecting saliva on penile swabs and male underpants; and spermatozoa would be expected in less than a quarter of penile swabs and three quarters of male underpants. As none of the samples had detectable levels of DNA which were suitable for meaningful comparison that did not match the donor or their partner, the expectation of detecting a DNA profile from the cellular background on penile swabs or underpants from a male who has not been involved in recent sexual intercourse is very low. The results of this study are extremely informative when evaluating the significance of blood, saliva, semen and DNA detected on the penile swabs and underpants of males in cases of alleged sexual assault.     

Illuminating the benefits and limitations of forensic light sources

Forensic light sources, such as a Crime-lite, are used in forensic laboratories and by police staff in the examination for, and detection of, biological material. Whilst the benefits of using forensic light sources are relatively well understood, their limitations are less-so. This report details the outcome of studies, validation and review by three forensic laboratories, as well as three case examples, to highlight both the strengths and weaknesses of the tested forensic light sources and to demonstrate that, whilst a useful preliminary screening tool, they should not be used in isolation without subsequent presumptive chemical testing. False positives and negatives are common, and the background substrate and specific biological material present can have a significant effect on the outcome of examination when using a forensic light source.     

Assessing the background levels of body fluids on hands

Forensic scientists are often asked to assist the court by evaluating the significance of finding body fluids on the hands of an individual; however, there is an absence of published data regarding the background levels of body fluids on hands. Whilst the scientist can use casework experience to inform the courts on the significance of the results, it would be advantageous to have data which could assist with this interpretation. This study was designed to ascertain the background levels of blood, semen, saliva, hairs/fibres and staining/debris on hands in the general population by sampling from delegates attending a scientific conference.The findings suggest that approximately one third of the population would be expected to have hairs or fibres on their hands and that females are more likely to have visible staining on their hands than males. Presumptive tests for blood and semen yielded negative results in all samples; however, almost 2 % of the samples were found to contain a very low number of sperm heads. In contrast, the majority of samples tested positive for the presence of saliva using the presumptive Phadebas® amylase test. The data supports the caution applied by forensic practitioners when evaluating the presence of saliva detected using the presumptive Phadebas® amylase test based on the lack of specificity and indicates that the RSID™-Saliva test would be more suitable to use.     

Examining the transfer of male DNA onto female underwear in simulated non sexual social interaction versus digital penetration to assist in the evaluation of results in casework scenarios

Experiments have been carried out by the UK and Ireland Association of Forensic Science Providers Body Fluid Forum (AFSP BFF) to determine the levels of male DNA, detected during Y-STR analysis, that may be expected on female underwear from non-sexual social interaction and digital penetration, versus non-sexual social interaction only. The data obtained strongly supports the existing assumptions made: whilst low levels of DNA may be inadvertently transferred to the inside surface of a female’s underwear during social interaction with a male, there is a low expectation of detecting a matching Y-STR profile to that male, which is suitable for statistical evaluation, unless he is a co-habitant of that female.
