随意伪装笔迹及其检验

随意伪装笔迹是故意伪装笔迹的一种，具有故意伪装笔迹的共性特征，但由于它是书写人凭自己主观意识，不借助任何特殊手段，不追求某种固定形式，任意改变自己的笔迹。随意伪装笔迹具有伪装意识的不确定性、盲目性和伪装结果的欺骗性的基本特点，决定了该笔迹伪装类型较多。检验时首先要注意区分是否为伪装，然后再进行下一步的检验。     

EU VAT frauds

The paper analyzes the VAT frauds issues in the European Union after the abolition of the internal customs. All the suggested solutions based on the origin principle create distortions in the “one market” and have a doubtful efficiency. The reverse-charge regime for all business to business transactions joint with VAT at the last stage also creates heavy discriminations. The current system based on the destination principle joint with ad hoc measures—such as specific reverse-charge, rebate and margin regime under evidence that VAT due has been paid, joint/several liability…—and a consistent information-exchange-system may provide a less distorting solution.     

Modeling and testing the diffusion of expectations: An EITM approach

This paper uses the empirical implications of theoretical models (EITM) framework to examine the consequences of the asymmetric diffusion of expectations. In the spirit of the traditional two-step flow model of communication, less-informed agents learn the expectations of more-informed agents. We find that when there is misinterpretation in the information acquisition process, a boomerang effect exists. In this equilibrium the less-informed agents’ forecasts confound those of more-informed agents. We apply the EITM approach to a key economic variable known to have a relation to economic fluctuations – inflation expectations. Using surveyed inflation expectations data for the period, 1978–2000, we find the boomerang effect exists. One implication of this finding pertains to economic policy and economic volatility: because policymakers have more information than the public, the boomerang effect can lead policymakers to make inaccurate forecasts of economic conditions and conduct erroneous policies which contribute to economic instability.     

Fatal splenic rupture following Heimlich maneuver: case report and literature review

The most effective resuscitative procedure in choking by foreign bodies is the Heimlich maneuver, described for the first time by Henry Heimlich (1974) and recognized by the US Surgeon General (1985) as the "only method that should be used for the treatment of choking from foreign body airway obstruction." If performed correctly, this lifesaving maneuver is associated with rare complications, of which the most frequent are rib fractures and gastric or esophagus perforations. Other rare traumatic injuries such as pneumomediastinum, aortic valve cusp rupture, diaphragmatic herniation, jejunum perforation, hepatic rupture, or mesenteric laceration have been described.However, we are unaware of previous reports of splenic rupture after Heimlich maneuver. We present an interesting case of fatal hemoperitoneum due to a hilar laceration of the spleen following a correctly performed Heimlich maneuver.     

"We are also normal humans, you know?" Views and attitudes of juvenile delinquents on antisocial behavior, neurobiology and prevention

This paper presents and discusses the views and attitudes of juvenile delinquents regarding the implications of genomics and neurobiology research findings for the prevention and treatment of antisocial behavior. Scientific developments in these disciplines are considered to be of increasing importance for understanding the causes and the course of antisocial behavior and related mental disorders. High expectations exist with regard to the development of more effective prevention and intervention. Whether this is a desirable development does not only depend on science, but also on the ethical and social implications of potential applications of current and future research findings. As this pilot study points out, juvenile delinquents themselves have rather mixed views on the goals and means of early identification, prevention and treatment. Some welcome the potential support and help that could arise from biologically informed preventive and therapeutic measures. Others, however, reject the very goals of prevention and treatment and express worries concerning the risk of labeling and stigmatization and the possibility of false positives. Furthermore, interventions could aim at equalizing people and taking away socially disapproved capacities they themselves value. Moreover, most juvenile delinquents are hardly convinced that their crime could have been caused by some features of their brain or that a mental disorder has played a role. Instead, they provide social explanations such as living in a deprived neighborhood or having antisocial friends. We suggest that the hopes and expectations as well as the concerns and worries of juvenile delinquents are relevant not only for genomics and neurobiology of antisocial behavior, but also for prevention and intervention measures informed by social scientific and psychological research. The range of patterns of thought of juvenile delinquents is of great heuristic value and may lead to subsequent research that could further enhance our understanding of these patterns.     

“Tampering to Death”: A Fatal Codeine Intoxication Due to a Homemade Purification of a Medical Formulation

Many homemade tamper processes of medical codeine formulations are available on selected “forums” on the Internet, where recreational codeine users claim to be able to purify codeine by removing additives, such as acetaminophen, to avoid or limit adverse effects. In this work, it is reported and discussed a fatal case of codeine intoxication. The findings of objects such as jars, filters, and tablets, and amounts of unknown liquid material at the death scene investigation suggested a fatal codeine intoxication after the tampering procedure called “cold water extraction.” Toxicological results obtained from the analysis of both the nonbiological material and the body fluids of the decedent integrated with the information collected at the death scene investigation confirmed the above‐mentioned hypothesis. This report underlines the importance of a tight interconnection between criminalistics and legal medicine to strengthen the identification of the cause of death and the reconstruction of the event.     

Ecological Crisis, Poverty and Urban Development in Latin America

This article deals with the social and ecological crisis in the urban regions in Latin America. To analyse the social and environmental conditions of Latin-American urban regions it is necessary to take into account two main factors: the high population and territorial growth of Latin American cities during the second half of the 20th century and the lack of an integral development which would have improved the urban quality of life. The imported market economy in Latin America, as a bad copy of the growth economy in the North, has generated a highly unequal development. The acceleration of the economic growth has gone hand in hand with the deceleration of development. Whereas the macro-economic rates improve, the indicators that measure qualitative evolution among sectors, territories and people have deteriorated. So, to explain the ecological crisis in Latin America, it is important to consider not only the different forms of environmental impact, but also the socio-economic factors and the availability of infrastructures. Therefore, this article describes the general social and economic development process in Latin America, and then examines the relationships between industrialisation and urbanisation in connection to the social and ecological conditions in urban areas.     

Fatal outcome of Ecstasy overdose

Consumption of amphetamine derivatives has considerably increased in Germany since the early nineties. Again and again intoxications with lethal outcome have also been reported, especially after physical activities such as intensive dancing. The authors present a case of an obviously suicidal intoxication of a 21-year-old man who was found dead with marked cuts on the right forearm. Toxicological tests showed in particular 3, 4-methylene-dioxymethamphetamine (MDMA). The results of the hair analysis revealed chronic consumption, but no cellular liver damage could be demonstrated. When examining the body fluids and organs, the highest concentrations by far were measured in the lungs (36.6 mg/kg), the liver (29.7 mg/kg) and the brain (29.1 mg/kg). The concentration in heart blood amounted to 10.8 mg/kg and was thus markedly higher than in peripheral blood (7.2 mg/kg). In the muscles concentrations ranged between 14.3 mg/kg and 20.2 mg/kg. On the basis of these concentrations and the available pharmacokinetic data the amount of MDMA probably consumed is assessed. It is demonstrated that for this assessment the concentrations in the muscular system are of special importance, as redistribution of highly lipophilic substances from the surrounding tissue is possible also in peripheral blood.
