Handling of inspired vaporized ethanol in the airways and lungs (with comments on forensic aspects)

Collections of expired air and chemical determinations of ethanol concentrations in inspired and expired air showed that during prolonged inspiration of ethanol (vapour)-containing air about 55% was absorbed by adult human subjects. The fractional absorption was not detectably affected by variations in tidal volume (0.7-2.1 liters), nor was it significantly reduced in experiments where, due to preceding oral intake, the ethanol concentration of systemic blood was up to 50 times higher than that of inspired air. In these experiments the difference between the rates of change in blood alcohol concentration (beta 60) during and before ethanol inhalation agreed well with values calculated from measured respiratory absorptions. Mass spectrometric recordings of ethanol concentration in expired air vs. expired volume, taken in a state of steady uptake, also gave absorption fractions of about 0.55, and showed that the concentration in end-expiratory air did not fall below some 30% of that of the inspired air. These and other findings show that a large part of ethanol being inspired is deposited in the airway linings to be released again to ethanol-free alveolar air expired through the airways. It is concluded that inspired ethanol deserves consideration as a source of elevations of blood alcohol concentrations.     

国际航空运输领域侵权行为法律适用问题研究

航空法是一个复杂的法律部门,既包括公法又包括私法,既包括国际法又包括国内法。航空器高速飞行和跨界运输的特点,加之各国航空运输领域民事责任立法之间的歧异,不免引发国际航空运输有关法律关系的法律冲突。华沙公约体系也只是在有限的范围内仅仅调整航空运输责任问题,而大量案件的处理需要由冲突规范来指引。受海商法的影响,航空法中的国旗国法原则逐渐被各国实践及公约所接受,但是,与船舶主要航行在无主权存在的海域航行不同,飞机主要在主权国家的上空,所以航空运输侵权行为能在多大范围内适用国旗国法原则是一个亟待解决的问题。本文主要从国际私法角度对航空运输侵权行为法律适用规则中的国旗国法原则及例外作初步探讨。     

Why Do Housing Mobility Programs Fail in Moving Households to Better Neighborhoods?

This article conceptualizes the relationship between housing instability, residential mobility, and neighborhood quality. We summarize the existing literature about residential mobility and housing instability and examine their potential interactions along three dimensions: (a) the reasons for a move, including a variety of push and pull factors; (b) mobility outcomes in terms of whether moves result in residing in a better or worse neighborhood than that of the prior residence; and, especially important for low-income households, (c) the degree to which the current move and past experiences of moving have been discretionary or forced. Housing instability is a cumulative concept, with involuntary moves at its center. This synthetic model of housing instability's impact on mobility outcomes suggests that the more instability a household has experienced, the less likely mobility moves are to occur, or, if they do occur, to be long lasting. Policy implementation may underestimate the interaction between cumulative housing instability and residential mobility in housing mobility policies. Thus, these interactions have implications for mobility policies, pointing toward a path for future research that inform policies to move low-income households toward both greater housing stability and better neighborhood outcomes.     

Death from Barotrauma Due to Compressed Air: A Medico‐legal Analysis

Lesions of the digestive tract due to barotrauma resulting from compressed air application are not common, are rarely lethal, and largely affect the sigmoid and descending colon. Moreover, their pathogenic mechanism is a topic of discussion because these lesions have multiple characteristics. Here, the authors describe an autoptic case of death from lesions of the ascending and transverse segments, with perforations and bleeding suffusions as well as ischemic areas covered the colonic wall that was extremely thinned, congested, and hemorrhagic, with considerable flattening leading to disappearance of the mucosal folds and with numerous petechial hemorrhages. The pathological framework of lung congestion made it possible to identify the mechanism responsible for this death as depletion of the heart's pumping function, which contributed significantly to the acute respiratory failure due to respiratory distress as well as to reduced mobility of the diaphragm due to intestinal distension. Acute heart failure played an important role in this death.     

Border work: surveillant assemblages,virtual fences,and tactical counter-media

The new technologies of bio-informatic border security and remote surveillance that have emerged as key infrastructures of reconfigured mobility regimes depend on various kinds of labor to produce the effect of bordering. The current retrofitting and technological remediation of borders suggests their transformation away from static demarcators of hard territorial boundaries toward much more sophisticated, flexible, and mobile devices of tracking, filtration, and exclusion. Borders require the labor of software developers, designers, engineers, infrastructure builders, border guards, systems experts, and many others who produce the “smart border”; but they also depend on the labor of “data-ready” travelers who produce themselves at the border, as well as the underground labor of those who traffic in informal and illegalized economies across such borders. Bordering increasingly relies on technological forms of mediation that are embedded within hi-tech, military and private corporate logics, but are also resisted by electronic and physical “hacks” or bypassing of informational and infrastructural architectures. In this paper we consider three socio-technological assemblages of the border, and the labor which makes and unmakes them: (1) the interlocking “cyber-mobilities” of contemporary airports including visual technologies for baggage, cargo, and passenger inspection, as well as information technologies for passenger dataveillance, air traffic control, and human resource systems; (2) the development of the Schengen Information System database of the EU, and its implications for wider migrant rights and internal mobility within the EU, as well as radical border media that have attempted to intervene in that border space; and (3) elements of the US–Mexico “smart border” regime known as the Secure Border Initiative Network (2006–2011), and those who have tried to tactically evade, disrupt, or undermine the working of this border.     

Korean elites: Social networks and power

During the period of rapid industrialisation, Korean business elites sought to establish a ruling alliance of state officials, politicians, business owners, and professional managers that formed a social coalition to influence the state and society as a whole, reinforced through extensive social and political networks with various ruling groups. The elite community has generated a high degree of self-recruitment and social closure through school, marriage and kinship networks. In this way, the leading sector of the Korean business elite has formed complex, often contingent, relations with the state elite, and acts as an integral part of the upper class in society.     

Posttraumatic Stress Disorder: Protective and Risk Factors in 18 Survivors of a Plane Crash

The aim of this study is to identify protective and risk factors related to the development of posttraumatic stress disorder (PTSD) on a sample of survivors from a single plane crash. Eighteen survivors were examined 6 months following the event. The subjects all underwent psychiatric interviews, Clinician‐Administered PTSD Scale structured interviews, personality and cognitive tests. Only 38.9% of them presented with all of the symptoms of PTSD; 22.2% showed no symptoms for PTSD; remaining survivors exhibited emotional/affective symptoms related to the event. In addition to the severity of the traumatic event itself, other risk factors identified were the loss of a relative, the manifestation of depressive symptoms, and the severity of physical injuries sustained. Low levels of hostility and high levels of self‐efficacy represented protective factors against developing PTSD.     

Suicidal Nitrogen Inhalation by use of Scuba Full‐Face Diving Mask

A 29‐year‐old man was found dead lying on the bed in a hotel room in a famous Slovak mountain resort. He had a full‐face diving mask on his face, connected through a diving breath regulator to a valve of an industrial (nondiving) high‐pressure tank containing pure 100% nitrogen. The breath regulator (open‐circuit type) used allowed inhalation of nitrogen without addition of open air, and the full‐face diving mask assured aspiration of the gas even during the time of unconsciousness. At autopsy, we found the typical signs of suffocation. Toxicological analysis revealed 94.7% content of nitrogen in alveolar air. Following the completion of the police investigation, the manner of death was classified as a suicide. Within the medico‐legal literature, there has been only one similar case of suicidal nitrogen inhalation described (1).
