Endemic violence in south africa: An od solution applied to two educational settings

This article discusses the endemic nature of violence in South Africa. The authors hypothesize that the culture in South Africa is autocratic in nature. They compare the socialization that occurs between democratic and autocratic families and the relationship this has to later problem-solving and conflict resolution behavior. People raised in an authoritarian culture need to develop skills that will enable them to learn an alternative to violence in conflict and problem-solving situations. The authors describe two educational interventions that followed this model. Available results are presented.

Both historically and today, violence in South Africa is endemic. Examples of South Africans committing violent acts because they feel justified fill today's media. Despite hopes and visions for a new South Africa and examples of goodwill and peaceful common ground between the different political positions, these violent acts emanate from all points of the political compass. Historically, we find examples such as the black tribal wars -- the African/Zulu wars, the Zulu/British wars, and the Anglo/Boer Wars.^(1),(2)

Although some positive processes of change occur in the country, a violent approach to problem-solving still remains. It is evident, both through research and perception, that all major population clusters (including whites, Africans, and other populations in South Africa) are predominantly authoritarian by virtue of their origin, their education, and their creed. This authoritarian culture may contribute toward the resistance against democratic processes and possibly heighten the opportunity for violence. The birth of liberation amplifies this dynamic situation. For all parties involved, liberation heightens the “fear for loss”⁽³⁾ and creates a non-productive power struggle. In this paper, we first explore why we believe that violence is endemic in this country, showing how an authoritarian culture may contribute to this problem. Second, we will describe two OD interventions presented in separate educational settings that were designed to reduce violence.     

欧洲货币联盟、财政危机和民主问责失效

在欧洲货币联盟,一些最重要的宏观经济管理工具已经让渡到了货币联盟的层面,各成员国难以用本国尚存的政策工具来应对宏观经济失衡.因此,尽管国际金融危机并非发源自欧洲,但货币联盟却大大增加了其成员国在面对危机时的脆弱性,并有可能使经济危机转变成一场民主合法性的危机.本文回顾了民主合法性和宏观经济管理之间的关系,简述了凯恩斯主义和货币主义政策模型的基本要素及其特定的政治影响,并揭示出欧洲货币联盟的创立如何改变了现有的国家制度,以及欧洲货币政策中的不稳定力量又是如何将某些成员国置于危险境地,使其在国际金融危机面前不堪一击.在结论部分,笔者分析了试图拯救欧元并改革货币联盟机制的方案会带来哪些可能的政治经济影响.     

Die Evaluation öffentlicher Politiken mit föderalistischen Vollzugsarrangements. Eine konzeptionelle Erweiterung des Stufenmodells und eine praktische Anwendung

Der vorliegende Artikel leistet einen Beitrag zur Konzipierung von Wirkungsmodellen für die Evaluation von öffentlichen Politiken mit föderalistischen Vollzugsarrangements. Das Phasenmodell des Policy‐Zyklus erfasst die Prinzipal‐Agent‐Probleme des Vollzugsföderalismus nur unzureichend. Es ist aus diesem Grund sinnvoll, in der Genesephase eine Zusatzschlaufe vorzusehen, die dem Umstand Rechnung trägt, dass in der Schweiz die Kantone beim Vollzug von Bundesgesetzen nicht nur Umsetzungs‐, sondern auch Programmierungskompetenzen haben. Diese Zusatzschlaufe impliziert allerdings beim häufig verwendeten Stufenmodell von Knoepfel und Bussmann (1997) für die Evaluierung öffentlicher Politik das Problem, dass es zu einer Vermischung der Evaluationsgegenstände auf Bundes‐ und Kantonsebene kommt. Diesem Umstand begegnen wir mit der Erweiterung des Stufenmodells, indem wir die beiden föderalen Ebenen getrennt betrachten und die Evaluationsgegenstände nicht generell, sondern entsprechend der Staatsebene definieren. Das Modell wird mit einer Anwendung aus der Evaluation des Krankenversicherungsgesetzes illustriert.     

A sudden death with lung embolism after inadvertent infusion of zinc oxide shake lotion

A 74-year old woman in postoperative treatment after a colonic surgery died immediately after perfusion of about 1.5 mL of a white emulsion which was believed to contain 1% propofol via cardiac catheter into the right atrium. It was strongly suspected that a syringe with a zinc oxide shake lotion (consisting of 20% ZnO, 20% talc, 25% glycerol and 35% water) which was intended for external treatment had been mistaken for the propofol syringe. During autopsy, an anatomic cause of death could not be found. In order to exclude an intoxication and to determine the significance of the perfusion fluid in this context, toxicological and histological investigations were performed. Propofol and other drugs applied to the patient were found in therapeutic or sub-therapeutic range. However, in comparison to a control case, the zinc concentrations determined by AAS were about 200 times higher in lung tissue, 10 times higher in heart blood and 3–4 times higher in kidney and liver tissue. No increase was seen in venous blood. Histology showed a strong embolism of the lung tissue with birefingent sharp-edged crystals, which were identified as the talcum, and an amorphous component (ZnO). The same embolism was seen to a medium extent also in the brain sections and to a low extent in heart, liver, pancreas and kidney. Pulmonary embolism by talcum and zinc oxide was established as the cause of death which occurred by syringe swap due to insufficient security precautions in the drug administration. The results are discussed in context of pulmonary microembolism cases frequently described for drug addicts after injection of crashed talcum containing tablets.     

Interpretation problems in a forensic case of abstinence determination using alcohol markers in hair

In a child custody case a mother with a longstanding history of alcohol misuse had to show absolute abstinence for one year. She entered a residential rehabilitation for six months and was tested two months later by way of a hair test for ethyl glucuronide (EtG) with the result of 22 pg/mg in the proximal 0-1cm segment and the segments 1-2 cm and 2-3 cm being negative. This was interpreted as a minimum alcohol intake of 20-50 units per week in the month before sampling. Since the mother denied any alcohol intake a second hair sample was collected seven weeks after the first and analyzed for fatty acid ethyl esters (FAEEs) by a second laboratory. A low concentration of 0.03 ng/mg was measured within the 0-6 cm segment of recently bleached hair and was interpreted as showing no evidence of alcohol use during the last six months. Three further hair samples were analyzed during the next nine months with low EtG values (<2.4-3.3 pg/mg, 0-3 cm segment) and low FAEE values (0.27-0.53 ng/mg, 0-6 cm segment). These findings were summarized as indicating continued low alcohol consumption over the past one year period. As a consequence of the conflicting results, the case was dealt with in a hearing before the Family Division of the High Court of London. It was concluded in the judgment that the evidence did not indicate that the mother had consumed alcohol in the period tested by the hair samples. It was stated that the evidence in this case highlighted the need for the exercise of considerable caution when hair tests for alcohol are being interpreted and relied upon, both generally and particularly in isolation, and that this case is a proper reminder of the need for expert evidence to be given in a manner according to the Practice Direction.     

General unknown screening in hair by liquid chromatography-hybrid quadrupole time-of-flight mass spectrometry (LC-QTOF-MS)

The retrospective investigation of the exposure to toxic substances by general unknown screening of hair is still a difficult task because of the large number of possible poisons, the low sample amount and the difficult sample matrix. In this study the use of liquid chromatography-hybrid quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) was tested as a promising technique for this purpose. In the optimized procedure, 20mg hair were decontaminated with water and acetone and two times extracted by 18h incubation with 0.5ml of a mixture of methanol/acetonitrile/H(2)O/ammonium formate at 37°C. A mixture of deuterated standards from different drug groups was added for quantification and method control. The united extracts were evaporated to a residue of 0.5ml and 5μl were injected without clean-up for LC-QTOF-MS measurement (instrument Agilent 6530) with positive electrospray ionization and in data dependent acquisition mode. For peak identification the accurate mass data base and spectral library of the authors was used which contains accurate mass CID spectra of more than 2500 and theoretically calculated accurate mass data of more than 7500 toxicologically relevant substances. Validation at the example of 24 illegal drugs, their metabolites and benzodiazepines resulted in limits of detection of 0.003-0.015ng/mg, and limits of quantification of 0.006-0.021ng/mg with good accuracy and intra- and interday reproducibility. The matrix effect by ion suppression/enhancement was 72-107% for basic drugs and 42-75% for benzodiazepines. Yields of the hair extraction above 90% were determined for 59 drugs or metabolites. The method was applied to hair samples from 30 drug fatalities and from 60 death cases with known therapeutic drug intake at life time. Altogether 212 substances were identified with a frequency per drug of 1-40 (mean 4.2) and per case of 2-33 (mean 10.2), between them 35 illegal drug related substances and 154 therapeutic drugs. Comparison with the data known from case histories and from the analysis of blood, urine and gastric content showed only a low agreement, with many unexpected drugs detected and many reported drugs not detected in hair. Basic drugs and metabolites such as opioides, cocaine, amphetamines, several groups of antidepressants, neuroleptics, beta-blockers or the metamizole metabolite noramidopyrine were found with high frequency whereas acidic and several neutral drugs such as cannabinoids, salicylic acid, furosemide, barbiturates, phenprocoumone or cardiac glycosides could not be detected with sufficient sensitivity, mainly because of the low ion yield of positive ESI for these compounds. The advantage of a comprehensive acquisition of all substances is paid by a lower sensitivity in comparison to targeted screening LC-MS/MS procedures. In conclusion, the procedure of sample preparation and LC-QTOF-MS analysis proved to be a robust and sensitive routine method in which the qualitative screening for a wide variety of toxic substances in hair is combined with the quantitative determination of selected illegal drugs.     

A New Approach to the Investigation of Sexual Offenses—Cytoskeleton Analysis Reveals the Origin of Cells Found on Forensic Swabs*

Abstract: There are forensic inquiries in which an identification of epithelial cell types would provide important probative evidence. In cancer diagnosis, this information is yielded by histological examination of cytokeratin (Ck). Therefore, we tested 19 antibodies against different Cks (Ck1, Ck2e, Ck4, Ck5‐6, Ck7, Ck8, Ck9, CK10, Ck13, Ck14, Ck15, Ck16, Ck17, Ck18, Ck19, Ck20, Ck903, PanCkAE1_3, and CAM5‐2) on histological sections of epidermis, buccal mucosa, vaginal mucosa, penis, urogenital tract, and rectum and could identify two antigens unique to buccal‐cell and vaginal‐cell (Ck4) and skin epithelial‐cell (Ck10) cytokeratin. Subsequently, we developed an immunocytological technique for distinguishing swabbed skin and mucosal cells up to at least 1 year after sampling. By the detection of the Ck4 and Ck10 mRNAs in biopsy and laser capture microdissection collected samples via quantitative real‐time polymerase chain reaction, we were able to confirm our immunological findings. Hence, this study offers techniques to discriminate between skin and mucosal cells (buccal and vaginal) in forensic casework.     

Die argumentative Logik der Tabakmandate des Alten Bern: Eine historische Policy‐Analyse

Zusammenfassung: Die Analyse dynamischer sozialer Phänomene stellt sowohl für die Sozial‐ als auch die Geisteswissenschaften eine Herausforderung dar. Ziel dieses Artikels ist es, einen auf Dunn (2004) aufbauenden Analyseraster auf seine Durchführbarkeit anhand einer Analyse von Policy‐Argumenten in historischen Dokumenten zu testen. Ein Längsschnittvergleich von Struktur und Form der Policy‐Argumente in den Tabakmandaten der Stadt Bern von 1659 bis 1723 zeigt einen Wandel der Tabakpolitik des Alten Berns in der Ortung der gesellschaftlichen Probleme, ihrer Ursachen, den damit festgelegten Massnahmen und derer Legitimation auf. Insgesamt impliziert dieses Resultat, dass unsere Methode für die Analyse historischer Policy‐Argumente geeignet ist.
