亨利·列斐伏尔的社会空间理论

社会空间是一种社会性的产品,空间产品相对过剩会产生经济危机。空间实践、空间表述、表述空间构成社会空间的三元辩证组合或者三元辩证法,第三项不是前两项的简单叠加,而是对它们所假定的完整性进行拆解和重构之后,形成的一种开放的选择项。社会空间包含着复杂的符号体系,空间三元组合类似于符号学的能指、所指、意指三项组合。身体是社会空间的生产主体,社会空间的生产从身体开始,处于异化状态的身体受权力、符号、知识三位一体控制。只有生产出社会主义差异空间,身体才能获得完全解放。当前全球经济危机的实质是城市化危机,中国正处于城市化危机的起始阶段。     

论社会资本的社会性——布迪厄社会资本理论的再澄清与再阐释

社会资本研究沿着关系效用的逻辑发展,只关注其经济性,而遮蔽其社会性,这违背了布迪厄提出资本理论以破解结构与能动二元对立的初衷。资本是结构和能动视角的双重蓄能,社会资本不仅仅是人与人的关系问题,更是人与群的互动问题,社会资本不能仅仅被理解为个体层次的关系资本,而是源于占据了一个熟识关系制度化的社会网络,其网络身份让个人可以借用集体共有的资本和信用。社会网络的社会性即在于网络整体的不可化约性,网络整合人,人也同时占据网络。徐福敦另立门户的例子具体阐释了社会资本如何在道德化、制度化和总体化的过程中进行积累即再生产的。     

Fatal Intoxication with Methoxetamine

Methoxetamine (MXE) is a new synthetic drug of abuse structurally related to ketamine and phencyclidine. A case of a 29-year-old male with acute toxicity related to the analytically confirmed use of MXE is reported. The man was found dead at his residence. Biological material was analyzed using liquid chromatography–tandem mass spectrometry. The concentration of MXE in urine of the deceased was 85 μg/mL. Despite the vial containing the blood sample being destroyed during transportation and the blood leaking out into the cardboard packaging, the blood level of MXE was estimated. After determination of the cardboard grammage (approx. 400 g/m³) and the mean mass of the blood obtained after drying (0.1785 ± 0.0173 g per 1 mL), the estimated blood concentration of MXE was found to be 5.8 μg/mL. The high concentration of MXE in blood and urine and the circumstances of the case indicate an unintentional, fatal intoxication with this substance.     

Animal Scavenging and Scattering and the Implications for Documenting the Deaths of Undocumented Border Crossers in the Sonoran Desert,

Since 1998, over 5500 people have died while attempting to cross the U.S.–Mexico border without authorization. These deaths have primarily occured in the Arizona desert. Despite the high volume of deaths, little experimental work has been conducted on Sonoran Desert taphonomy. In this study, pig carcasses were used as proxies for human remains and placed in different depositional contexts (i.e., direct sunlight and shade) that replicate typical sites of migrant death. Decomposition was documented through daily site visits, motion-sensitive cameras and GIS mapping, while skeletal preservation was investigated through the collection of the remains and subsequent faunal analysis. Our results suggest that vultures and domestic dogs are underappreciated members of the Sonoran scavenging guild and may disperse skeletal remains and migrant possessions over 25 m from the site of death. The impact of scavengers and the desert environment on the decomposition process has significant implications for estimating death rates and identifying human remains along the Arizona/Mexico border.     

Comparing Electronic News Media Reports of Potential Bioterrorism-Related Incidents Involving Unknown White Powder to Reports Received by the United States Centers for Disease Control and Prevention and the Federal Bureau of Investigation: U.S.A., 2009–2011

There have been periodic electronic news media reports of potential bioterrorism-related incidents involving unknown substances (often referred to as “white powder”) since the 2001 intentional dissemination of Bacillus anthracis through the U.S. Postal System. This study reviewed the number of unknown “white powder” incidents reported online by the electronic news media and compared them with unknown “white powder” incidents reported to the U.S. Centers for Disease Control and Prevention (CDC) and the U.S. Federal Bureau of Investigation (FBI) during a 2-year period from June 1, 2009 and May 31, 2011. Results identified 297 electronic news media reports, 538 CDC reports, and 384 FBI reports of unknown “white powder.” This study showed different unknown “white powder” incidents captured by each of the three sources. However, the authors could not determine the public health implications of this discordance.     

Radiographic Identification Using Midline Medical Sternotomy Wires,

Forensic anthropologists are regularly asked to assist with the identification of unknown individuals using comparative medical radiography. This study addressed the use of midline medical sternotomy wires as a means for personal identification. Antemortem and postmortem radiographic comparisons were completed by 46 professional forensic anthropologists and anthropology graduate students familiar with comparative medical radiography as a technique for assessing identification. Participants were asked to make five radiographic matches from a pool of 20 radiographs. Participants also completed an anonymous survey detailing their education level and experience making radiographic comparisons. Participants were 99.5% accurate in matching the radiographs. Sensitivity was 98.7%, and specificity was 99.7%. Logistic regression analysis found no statistically significant differences in the participants' ability to make a correct match. As the high accuracy rates indicate, the shape, size, and various characteristics of the sternotomy wires are individualizing and can confidently be used when assisting with personal identification cases.     

Identification of a Buried Cadaver Based on Finger Ridge Characteristics of a Hand Protected by a Latex Glove

This paper presents the case of a cadaver buried in a pine grove, in loamy soil at a depth of about 1.8 m. The case is quite interesting due to the fact that one hand of the victim was bare and the other one was clad in a latex glove. In the laboratory, the severed hands were gently washed with water. The left palm exhibited signs of advanced decomposition. The ridges were visible only on the thumb. The gloved hand was found to be in much better condition. There were signs of saponification on the palm. Ridges on both the palm and all fingers were visible. The fingers of the right hand, palm prints, and the thumb of the left hand were successfully matched against a ten-print card. The match provided the police with a positive identification of the missing person.     

Effects of Homeopathic Mother Tinctures on Breath Alcohol Testing

In some countries, it is illegal to drive with any detectable amount of alcohol in blood; in others, the legal limit is 0.5 g/L or lower. Recently, some defendants charged with driving under the influence of alcohol and have claimed that positive breath alcohol test results were due to the ingestion of homeopathic mother tinctures. These preparations are obtained by maceration, digestion, infusion, or decoction of herbal material in hydroalcoholic solvent. A series of tests were conducted to evaluate the alcoholic content of three homeopathic mother tinctures and their ability to produce inaccurate breath alcohol results. Nine of 30 subjects gave positive results (0.11–0.82 g/L) when tests were taken within 1 min after drinking mother tincture. All tests taken at least 15 min after the mother tincture consumption and resulted in alcohol-free readings. An observation period of 15–20 min prior to breath alcohol testing eliminates the possibility of false-positive results.     

Differences in Handwritings of Schizophrenia Patients and Examination of the Change after Treatment

The aim of this study was to analyze the differences between the handwritings of schizophrenia patients and healthy subjects in addition to the changes that occurred in schizophrenia patients' handwriting in response to the treatment. The test subjects were 29 schizophrenia patients and 29 healthy individuals with the same age, gender, and dominant hand. The changes in the handwritings were examined according to 14 different parameters. On the day of admittance, the percentage of extra letters was 16.7%, and after 7–10 days of hospitalization, it rose to 33.3%. The percentage of skipped words decreased from 29.2% to 16.7% after 7–10 days of hospitalization, and to 10% after 3 weeks. The letters written by schizophrenia patients are significantly larger in height and width compared to the control group. The schizophrenia patients showed a higher incidence of crossed-out letters, adding extra words, missing punctuation as well as missing words.     

Sudden Death Due To Acute Cocaine Toxicity—Excited Delirium in a Body Packer

Excited delirium denotes a life-threatening medical condition characterized by the acute onset of agitated and violent behavior that often results in a sudden and unexplained death. Cocaine-induced excited delirium refers to fatal cocaine intoxication with the following symptoms occurring sequentially: hyperthermia, delirium with agitation, respiratory arrest, and death. We present a case of cocaine-induced excited delirium in a cocaine “body packer” or a “mule”, specifically an individual who attempts to smuggle cocaine within the body. Investigators at the scene initially suspected homicide due to the victim's sharp and blunt force injuries. Three rubber packets containing cocaine were removed from the victim's rectum. Blood toxicological analysis revealed an alcohol concentration of 0.016 g/100 and cocaine >1 mg/L. The forensic pathologist should consider cocaine-induced excited delirium when an individual exhibits aggressive behavior, unexpected strength, and resistance to pain who dies suddenly. Further analysis should be performed during the scene investigation and autopsy for evidence of body packing.
