Why not Africa? – Growth and Welfare Effects of Secure Property Rights

This paper presents the long-run equilibrium and developmentdynamics in the neoclassical growth model and a simple modelof endogenous growth when property rights are absent. Theresults are compared to the outcome in a corresponding modelwith secure property rights. The main findings are that thereexists a considerable gain in level and growth of consumptionfrom establishing secure property rights, that economicperformance without property rights worsens with an increasingnumber of competing social groups, and that the existence orabsence of property rights explains conditional convergence.     

Semen analysis using methods of molecular genetics--a case report

The presented case report describes the exclusion of the suspect of a sexual offence by means of methods of molecular genetics. Pretests for prostate-specific antigen performed at the beginning of the investigation and cytological sperm tests were negative. Nevertheless, by combining the methods of differential lysis and DNA quantification a small number of spermatozoa could be demonstrated in the trace evidence. Subsequently, the profile of the woman's boyfriend, with whom she had had unprotected vaginal intercourse two days before the incident, could be detected in the fraction of the hard lysis.     

Intramuscular bleeding in deaths from an internal cause: forensically significant differential diagnosis between external trauma and hemorrhages occurring during agony

Five cases of death from an internal cause are described in which bleeding into the muscles of the neck, the region of the shoulder girdle, the back of the thorax and partly the arms occurred during agony. As the cause of death was unclear at first and a violent crime could not be ruled out, a forensic autopsy was ordered in the course of which hemorrhages were detected which raised the differential diagnostic question whether extravasation might have been caused by an impact of blunt force. However, thorough investigation of the macroscopic and especially the microscopic structure of the lesions provided clear evidence that all the hemorrhages were due to internal causes. The pattern of these muscular lesions suggests intensified breathing with dyspnea leading to ruptures of the accessory respiratory muscles. Intramuscular bleedings of this type are a well-known phenomenon in legal medicine in connection with death by drowning, but have not been described in the medicolegal literature in cases of natural death from an internal cause so far.     

A distributional theory of government growth

This article presents a closed form solution for time-consistent taxation and public spending in a dynamic game between government and median voter. Extending Meltzer and Richard’s static analysis of government size the article offers a theory of growth of government. At low stages of economic development the median voter, identified as a relatively poor worker, prefers to have no or only small redistributive taxation in order to foster savings. Through this channel he expects improvements of his labor productivity and wage. At higher stages of development, however, when capital is relatively abundant and prospects of further labor productivity gains through capital accumulation are smaller, the incentive to tax and redistribute income rises. Yet, in line with previous work on growth and infrastructure spending the median voter prefers a constant share of productive public spending at all times. Hence, government growth is solely driven by an expanding welfare state.     

Experimental tests for the validation of active numerical human models

The development of numerical human models is a topic of current interdisciplinary research. In the field of automotive safety these models can be applied for the optimization of protection systems. In forensic research human models can be used for the investigation of injury mechanisms and for the prediction and reproduction of injury patterns. However, up to now human models have been validated on the basis of PMHS tests without considering the effects of muscle activity. This paper shows two experimental volunteer test set-ups for the generation of experimental validation data. In a pendulum set-up the influence of muscle activity on the human kinematics was investigated. A drop test set-up was developed for the analysis of the effects of muscle activity on impact response characteristics of muscle tissue. Experimental results, presented in this paper, can be used for the validation and optimization of active numerical human models.
