The burial of a body can affect plant communities through mechanical disturbance and nutrient balance alteration. We performed an experimental trial using five swine carcasses buried in an open site in Italy. Vegetation dynamics was monitored recording monthly every plant individual on a regular sampling grid during 1 year on the graves, on an empty control grave, and on an undisturbed plot. Plant species composition and cover were significantly different between the disturbed and the undisturbed plots. Disturbed plots showed the increase in ruderal species and the reduction in stress-tolerant ones. Graves and the control grave could not be distinguished from each other. Disturbance was the main factor affecting plant cover, while the presence of a buried body did not affect vegetation dynamics. However, disturbance could be easily detected; the functional approach seems promising for the identification of dynamic patterns to be used in different biogeographic and ecological contexts. 相似文献

We performed an experimental investigation to assess whether the “restricted auction” mechanism proposed by Berkovitch, Israel
and Zender in 1997 works effectively as an optimal bankruptcy law or not. An optimal bankruptcy law is a commitment device
that implements efficient choices both before (ex ante) and after (ex post) financial distress, even if moral hazard is binding.
We designed an experiment focused on ex ante efficiency and we found that the restricted auction mechanism was able to direct
an optimal amount of effort toward entrepreneurial activities. This result confirms the theoretical predictions. Nonetheless,
we found that under a plain unrestricted auction mechanism our experimental subjects chose to allocate into their firms a
larger amount of effort than that predicted by theory. Although difficult to justify on theoretical grounds, this experimental
evidence is robust. Our behavioral interpretation is that this result is due to “moral sentiments”, such as the natural propensity
of subjects toward socially desirable behaviors. In fact, we show that it vanishes once these motives are removed. 相似文献

The radiological search for GSR is crucial in burnt material although it has been rarely tested. In this study, thirty‐one bovine ribs were shot at near‐contact range and burnt to calcination in an oven simulating a real combustion. Computed tomography (CT) and magnetic resonance (MR) were performed before and after carbonization and compared with former analyses with DR (digital radiography); thus comparing the assistance, the radiological methods can provide in the search for GSR in fresh and burnt bone. DR demonstrated the greatest ability in the detection of metallic residues, CT showed lower abilities, while MR showed a high sensitivity only in soft tissues. Thus, DR can be considered as the most sensitive method in the detection of GSR in charred bones, whereas CT and MR demonstrated much less reliability. Nonetheless, the MR ameliorates the analysis of gunshot wounds in other types of remains with large quantities of soft tissues. 相似文献

This paper will mainly focus on the EU approach to net neutrality, notably the adequacy of existing and future EU rules to tackle the issue and the ongoing policy debate. It will also consider whether the market has effectively worked around the regulatory lacunae by looking into the relationships between the telecoms industry, as a regulated sector, and the over-the-top (OTT) players. In this regard, it will explore to what extent there is a real battle between telcos and OTTs or if both parties are already finding their own ways to overcome their (apparent) disputes. 相似文献

The discovery of mummified bodies in domestic settings is not unusual in the medico‐legal context. It is often a marker of social isolation, even in our urban modern society, and usually occurs among elderly people living alone or in precarious conditions. However, bereaved subjects can sometimes be found managing their grief by deliberately keeping the corpses of their loved ones at home. Investigation of these atypical cases can be challenging and often requires a multidisciplinary effort by different forensic specialists. We report two cases of people who lived for several months with the mummified remains of a relative. In both cases, the judge ordered a forensic psychiatry assessment of the survivors’ competency and the reasons for this peculiar behavior, which is regarded as abnormal in our society. Case 1 describes a shared psychosis, which developed out of a condition of extreme seclusion of the entire family. Case 2 shows that even a mild personality disorder on which a series of traumatic events operates can trigger psychotic decompensation, causing extreme denial of the reality of death. The analysis of these cases contributes to our knowledge of the scantly studied phenomenon of “Living with the Dead” and raises questions about the psychopathology behind it. It is useful to identify subjects who are more prone to developing this “deviant” behavior, in order to distinguish people with mental illness from those who merely want to profit from the death of a loved one. 相似文献

马来西亚是除中国大陆、台湾、港澳地区以外唯一保留华文教育体系的国家并且华文教育体系完备,具有鲜明的国别特点。对2000年以来马来西亚华文教育的相关文献进行梳理和归纳,主要是整体状况、学校、教材、课程、师资与学习动机六个主题。新世纪马来西亚华文教育总体呈现以下五个特点:华文教育的推广和国家建设之间的博弈;各层次华文学校皆在夹缝中生存;华文教材和课程体系不完善且水平参差不齐;华文师资紧缺且教师专业素质不高;华文学习动机体现了深层次的语言意识形态。马来西亚华文教育在华人的努力和奋斗下,整体上既有困境和挑战也有光明的未来,发展道路并不平坦,但由于各种国际和国内因素的交织,尚有较大的发展空间。 相似文献

Skull and Encephalic Injuries Caused by Beach Umbrellas: Case Reports and Review of Literature 下载免费PDF全文

This study reports two unusual cases of skull‐encephalic injuries in bathers that were caused by violent impacts with beach umbrellas. The first case concerned a 36‐year‐old man who, while lying on a sun bed, was struck on his left temple by a beach umbrella, which had been blown away by a gust of wind. The second case concerned a six‐year‐old child who was struck on the right temporal region while he was playing on the sand. Both subjects died. A review of the literature was carried out. Various skull and brain injuries caused by several objects were found, but no injuries caused by beach umbrellas were detected. There were only cases of injuries caused by normal umbrellas. These cases showed that several objects can be responsible for traumas causing skull and brain injuries, therefore forensic investigation must be supplemented by circumstantial data. 相似文献

One Hundred and One Cases of Plastic Bag Suffocation in the Milan Area Between 1993 and 2013—Correlations,Circumstances, Pathological and Forensic Evidences and Literature Review 下载免费PDF全文
Graziano Domenico Luigi Crudele M.D. Domenico Di Candia B.Sc. Guendalina Gentile B.Sc. Matteo Marchesi M.D. Alessandra Rancati M.D. Riccardo Zoja M.D. Ph.D. 《Journal of forensic sciences》2016,61(2):361-366
Plastic Bag Suffocation is a rare cause of death in developed countries and almost unknown in the rest of the world. This study aims to retrospectively evaluate cases of PBS _asphyxia in Milan's Department of Legal Medicine from 1993 to 2013. Cases were selected from the database of 21,472 autopsies performed in the considered timeframe. One hundred and one cases were considered to be cases of Plastic Bag Suffocation, comprised of 100 suicides, no accidental events and 1 homicide. The most relevant elements pertaining to this type of death were evaluated for both the corpses and the crime scenes. From this study the typical PBS victim is an adult male, aged 52.3 years on average, depressed or afflicted by chronic or terminal diseases, and found at home. In 42.6% of cases, the victims were found with the plastic bag still positioned over their head, fastened by tying. Also common among these cases are drugs, alcohol and chemical abuses. According to the collected data, it is impossible to outline a pathognomonic detrimental background that leads to this cause of death. Crime scene investigation is, therefore, the one and only technical resource for evaluating these cases. 相似文献
