Invalid Voting in German Constituencies

This article studies invalid voting, which has received very little attention so far, given the broad interest and substantial relevance of voting behaviour research. Existing evidence is mostly limited to rather specific and hardly representative countries. Yet, the extent of invalid ballots is not negligible. Despite undemanding electoral rules, more invalid votes are cast in German general elections than votes for niche parties. Against this backdrop, the article describes prevalence of invalid voting in the mixed electoral system of Germany and tests explanations of its variation between constituencies. Analysing data from the most recent Bundestag Election, results give clear support to politico-institutional explanations: voters are more willing to waste their vote if second-order elections are held concurrently. Specifically under the plurality rule, more (first) votes are wasted if there are large shares for parties without direct candidates and many competing candidates.     

Age assessment of ivory by analysis of 14C and 90Sr to determine whether there is an antique on hand

This report describes the histological changes observed in the heart a young methamphetamine abuser who died of heart failure. Most of the microscopic changes in the heart have previously been described in experimental animals, but never clearly illustrated in man. Gross examination of the heart revealed concentric myocardial hypertrophy (heart weight 470 g versus median predicted weight of 312 g). Areas of old myocardial infarction were also evident, along with enzymatic evidence indicating that a new infarct had occurred. Myocardial remodeling was extensive with perivascular and interstitial fibrosis, cellular vacuolization, and ongoing myocyte destruction with proliferation of fibromyocytes in the intestitum. Of note were the widespread, bizarre looking, distorted, cell nuclei. They were reminiscent of those seen in viral-induced dilated congestive cardiomyopathy. Clinical chemical measurements also showed unequivocal evidence of both evolving infarction and profound heart failure, with a BNP > 5000. This pattern has not previously been reported in humans, probably because forensic pathologists rarely examine the hearts of methamphetamine abusers microscopically. If the pattern observed here is typical for methamphetamine-induced cardiotoxicity, it could well explain increasing reports of heart failure in methamphetamine abusers. It might also be diagnostic for the disorder.     

Cardiac Changes Due to Electronic Control Devices? A Computer‐Based Analysis of Electrical Effects at the Human Heart Caused by an ECD Pulse Applied to the Body's Exterior

Electronic control devices (ECDs) deliver high‐voltage, low‐current energy pulses temporarily paralyzing a person. For the ECD–human interaction, we have developed a computer model using the SEMCAD program within which to simulate the electrical effects throughout the body resulting from the imposition of an ECD pulse at a particular point on the body surface. Our human body models were based on cross‐sectional MRIs and CT scans, with the dielectric properties of the various tissues assigned based on previously published values. We simulated the application of a single ECD pulse and calculated the resulting electric field strength and current and charge densities at different body locations. The results were compared with corresponding values obtained by other researchers in similar simulations. Furthermore, we simulated an application of a pulse of 20‐millisecond duration equal to the European household current of 50 Hz and to the ventricular fibrillation threshold. The resulting current level indicated at the heart muscle was 1/5 the level considered the threshold for triggering ventricular fibrillation.     

公务员惩戒制度——中德公务员法的比较分析

针对公务员惩戒制度,中国《公务员法》进行了一定范围的法律规范。但与德国《联邦惩戒法》、《联邦公务员法》中的相应制度安排相比,中国目前的规定较为抽象并缺乏可操作性。尤其是针对公务员在惩戒程序中的部分基本权利,例如查看档案权、参与调查权、委托律师权等,《公务员法》均未作出规定。从整体上看,中国制度下的公务员在程序中的角色过于被动,几乎无机会主动参与调查环节。为了确保被惩戒公务员合法权利的保障并提高整体程序的客观性,可考虑将德国法律中部分具体权利保障制度纳入到《公务员法》今后的修订范围当中。     

Laminated safety glass as an intermediate target: a wound ballistic study

Various 9‐mm ammunitions (A1, A4, A5, ST, GS, GSb, P.E.P., SeCa, HP, PTP/s, VM, McVG, DM41, PTP, SX2, PT, and MEN frangible) were tested regarding their velocity, energy, angle of impact, and potential wound channel after penetrating a car window at 30° and 90°. Test materials were gelatine, soap, and pig cadavers. The velocities of the projectiles were between c. 288 and 430 m/ses, the energy spread between 394 and 564 J. Handgun bullets fired through vehicular side window glass lose substantial energy reducing the effectiveness of the ammunition. This effect is greater when fired at an angle of 30° compared to 90°. At a shooting angle of 90°, none of the different projectiles showed remarkable differences considering its wound ballistic features. Accuracy is maintained at a 90° angle but seriously impaired at 30°. None of the examined ammunition complied with the demanded wound channel effectiveness of 30–60 J/cm.     

Determination of the mineral content and the transparency of the root dentine of human teeth

One hundred and fifty-six teeth were extracted from corpses aged between 15 and 79 years. Of these, 101 teeth were selected for measurement of the mineral content of the root by photon beam absorption. Six or seven cross-sections were measured in each root, and the mean values calculated for the apical, medial, and coronal part within each decade. Further, 20 selected teeth were embedded in methacrylate and the length of the zone of transparency determined in longitudinal sections. There was no significant age dependency of the root's mineral content. There was no correlation between the extent of transparency and the mineral content.     

Cytochemical detection of ABH antigens in human body fluids

The use of the peroxidase-anti-peroxidase (PAP) technique has been described previously for the detection of cellular antigens and in particular ABO antigens from tissue samples (Pedal and Hülle 1984; Pedal and Baedeker 1985; Pedal et al. 1985). In this survey, the PAP method has been employed to study the detection of ABO antigens in cells from body fluids of particular interest to forensic science, namely buccal cells and vaginal cells. Also tested, but in a limited number, were mixtures of body fluids and semen samples. No false reactions were obtained from buccal cells, all samples corresponding to the ABO blood type of the donor. Preliminary results from vaginal cells, vaginal/buccal cell mixtures, and semen were encouraging but must be treated with caution due to the limited number tested. Vaginal smears contaminated with semen showed varying degrees of nonspecificity.     

Forensic medicine and toxicologic aspects of 2-propanol poisoning

Two cases of poisoning with 2-propanol (isopropylalcohol) are reported. In one case, nail polish remover was drunk by a 2-year-old child. The concentration of 2-propanol and its metabolite acetone in the blood could be observed over a period of approximately 50 h. The highest concentration of 2-propanol determined was 4.22 g/l. Acetone reached a maximum value of 2.27 g/l 12 h after ingestion. The child survived without any observable after-effects. In the second case, a 35-year-old man drank ethanol in addition to 2-propanol. The poisoning was lethal. The possible time of intake before death is discussed in relation to the estimated levels of ethanol, 2-propanol and acetone found in the blood and urine. The histomorphological findings are often important as well with regard to time of intake.
