Weapon identification using antemortem computed tomography with virtual 3D and rapid prototype modeling-A report in a case of blunt force head injury

This research shows the exfoliation of the anterior dentition has significant potential to aid in establishing the minimum length of the post-mortem interval. Accumulated degree days (ADD) were used to quantify the decomposition of the periodontal ligament, represented by post-mortem exfoliation of the incisors. After subjects were removed subsequent to disturbance by scavengers and time limitations on the study, the final sample size was 36 incisors from the maxillae and mandibles of seven pigs (Sus scrofa). Average daily temperature was calculated using hourly temperature data recorded using DS1921G thermochrons for the duration of the project (June 14-December 17, 2008). During this period, six teeth (16.7%) were exfoliated. ADD for these six teeth ranged from 1539.7 °C to 2006.7 °C. The average ADD required for exfoliation was 1788.0 °C (SD=198.1 °C). No differences in ADD required for exfoliation were observed between the maxillary and mandibular teeth (t=2.085; p=0.128).     

Insect succession and carrion decomposition in selected forests of Central Europe. Part 1: Pattern and rate of decomposition

Pig carrion decomposition and insect succession were monitored in different seasons and forests of Central Europe. Pattern of decomposition as well as onset, duration and rate of decompositional processes were measured. Pattern of decomposition was the same in almost all cases with putrefaction, active and advanced decay. In the majority of carcasses active decay was driven by larvae of Calliphoridae with a clear seasonal shift in dominant taxa. However, in some spring, alder forest cases active decay was driven by larvae of Necrodes littoralis (Coleoptera: Silphidae). As a rule the mosaic decomposition was observed. In spring a significant delay in onset of all decompositional processes was found. Season significantly affected rate of active decay due to a much higher rate in summer. Decomposition in alder forest proceeded faster than in pine-oak forest and hornbeam-oak forest. Differences between the latter two forests were practically negligible. Implications for forensic entomology are discussed.     

Punitive Attitudes in Poland – The Development in the Last Years

Research results show that Poland’s population considers sentencing policies of courts to be too lenient, and represents often even extremely punitive attitudes. This punitiveness may have increased in recent years. For instance, results of surveys on attitudes towards the death penalty show widespread support for that kind of sanction, in recent years higher than under the communist regime. On the other hand, answers to the ICVS item regarding punitivity (asked in Poland five times) do not necessarily show Poles being extremely punitive against the background of other countries. With respect to those proposing imprisonment, Poland is among average countries, although duration of this imprisonment is above the average, especially for Europe. All this may indicate that attitudes towards punishment of offenders constitute a complicated issue. This is confirmed by the results of recent research confirming that there is a gap between abstract declarations about support for the death penalty and punishment proposed in more concrete cases. This research confirmed that there is a substantial majority of those supporting the death penalty in abstract terms. However, only in one sweep (out of three) and in one of five homicide cases respondents were confronted with, there was a majority supporting actual imposition of the death penalty. The fact that Poles are not necessarily always unusually punitive may be also confirmed by a rather broad support for mediation and restitution as a way of reacting to offences.
