Reverse engineering--rapid prototyping of the skull in forensic trauma analysis

Rapid prototyping (RP) comprises a variety of automated manufacturing techniques such as selective laser sintering (SLS), stereolithography, and three-dimensional printing (3DP), which use virtual 3D data sets to fabricate solid forms in a layer-by-layer technique. Despite a growing demand for (virtual) reconstruction models in daily forensic casework, maceration of the skull is frequently assigned to ensure haptic evidence presentation in the courtroom. Owing to the progress in the field of forensic radiology, 3D data sets of relevant cases are usually available to the forensic expert. Here, we present a first application of RP in forensic medicine using computed tomography scans for the fabrication of an SLS skull model in a case of fatal hammer impacts to the head. The report is intended to show that this method fully respects the dignity of the deceased and is consistent with medical ethics but nevertheless provides an excellent 3D impression of anatomical structures and injuries.     

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.     

“He did everything he possibly could for me”: medical malpractice claimants’ experiences of lawyer–client relations

Lawyers are obliged to act in the interests of their clients, however, it is not clear how lawyers should do this in practice. Should lawyers follow their clients' instructions without deviation, should they actively manage their clients' expectations, or as many studies suggest, do lawyers place their own interests first? This paper examines how lawyers interact with medical malpractice claimants. It reveals that lawyers take a client-aligned approach, where lawyers acknowledge their client's goals, but do not necessarily do what the client says. We argue that this approach is made necessary by legal and organisational constraints which limit the ability of lawyers to produce the types of outcomes that their clients want.     

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。     

The Impact of Exchange Rate on the Growth of Nigerian Economy From 1960 to 2010

This paper examined the impact of exchange rate on the growth of Nigerian economy using time series data from 1960 to 2010. The paper utilized secondary data and explored various econometrics and/or statistical analytical （E-view 7.0） method to examine the relationship between exchange rate and economic growth. The paper tested the stationarity--through unit root test （ADF）, Vector Autoregressive Estimates （VARs）, cointegration test, Granger-Causality test of Nigeria＇s time series data, and used an error correction model through over-parameterization and parsimonious model to determine the long-run relationship among the variables examined. It was discovered from the findings that the growth rate of national income was directly related to domestic investment and economic growth. The paper recommended based on the econometric results among others that the government should ensure that prevailing economic situation in Nigeria is tolerable in order to reap the full benefit/advantage of exchange rate policy, encourage domestic production of goods and services to enable the domestic economy to benefit from the exchange rate policy, ensure the stability of macroeconomics variables, and ensure the exchange rate policy which is to encourage exports and discourage imports in order to avoid cash drain （or flight） in the economy.     

The Evolving “Nature” of Environmental Risk: A Responsible Approach for Residential and Commercial Real Estate

Environmental losses suffered by commercial and residential real estate owners are becoming more frequent and severe due to evolving regulatory regimes and the changing global climate. This article reviews the nature of environmental risk, specifically within the context of a changing climate, and proposes the large-scale installation of green infrastructure as both a business opportunity for insurers and a responsible approach.     

Driving under the influence of amphetamine-like drugs

Scientific opinions differ whether the use of stimulants causes deterioration in driving skills. In 1857 of 8709 cases of driving under the influence of drugs, amphetamine-like drugs (amphetamine, methamphetamine, and methylendioxyamphetamine) were present either alone or together with other licit or illicit drugs. In 338 cases, amphetamines were the only psychoactive substance group in plasma at mean, median, and highest concentrations of 0.18, 0.12, and 1.05 mg/L, respectively. A widespread opinion is that after the consumption of amphetamines, centrally stimulating effects with corresponding consequences on safe driving are expected. In contrast, many cases were observed that rather suggested an influence of centrally sedating substances when considering the psycho-physical conditions. Relations between concentration and effect could not be established. The apparent sedation is probably the consequence of sleep deprivation during an amphetamine binge and the after-effects of the drug.     

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.
