Death following crude oil aspiration

This is a report on three deaths following oil aspiration by workers in petrol tankers. Lung aspiration was demonstrated by the presence of a yellowish-brown material in the alveolar spaces, which was difficult to identify by optic microscopy. Volatile hydrocarbons from petroleum were identified in lung samples by gas chromatography/mass spectrometry.     

Comment on "Voter Turnout and the National Election Studies"

A recent article by Barry Burden in Political Analysis alertsus to a steadily increasing gap during presidential electionyears between self-reported turnout in the NES (National ElectionStudies) and "official turnout" figures based on the voting-agepopulation (VAP), and points to declining response rates asa culprit. Changing the baseline from the VAP to the VEP (voting-eligiblepopulation) significantly changes these conclusions, and pointto panel effects as a culprit. The rise in the gap was not linear,but it does emerge rather suddenly in 1996. Gaps between NESself-reported turnout and VEP estimates are higher in presidentialelection years than in off-years, and self-reported turnoutis higher among long-term panel participants than among cross-sectionrespondents in multielection panels.     

Solid phase micro extraction coupled with on-column GC/ECD for the post-blast analysis of organic explosives

Gas chromatographic analysis with electron capture detection is very sensitive to post-blast residues and useful for the determination of organic explosive molecules. But many compounds extracted from the matrices may interfere with the explosives. Using SPME, most interfering compounds are eliminated so the identification is easier. Another advantage of the technique is a low limit of detection. In this study, four different SPME fibers were tested to analyze the most common encountered organic explosives including nitro aromatics, nitramines and nitro-esters. Different parameters were tested (desorption time, agitation, ...) and a special device has been created to optimize the agitation. Direct desorption effect of the SPME fiber on the column compared to normal split-splitless injection is shown. In this way, the degradation of the most sensitive molecules is decreased. An application to a real case is also described in this paper.     

The Structure of Political Competition: Dimensions of Candidate and Group Evaluation Revisited

In this paper, we take a fresh look at the structure of sociopolitical conflict through confirmatory factor analyses of survey data gathered in Florida during the presidential campaign of 1996. Our analysis shows both stability and change in the electorate. In line with prior research, a single bipolar partisan dimension underlies the mass public's evaluations of political leaders, though national figures fit more comfortably on this continuum than do those at the state level. Citizens' evaluations of key sociopolitical groups reflect orthogonal cultural disputes, class divisions, and conflicts relating to issues of social control. While all three of these dimensions impinge to some degree on voters' conceptions of party and ideology, our findings point to the leading role that cultural issues now play in shaping ideological images and identities.

The False Narrative On Basic Rights

正The U.S. has made human rights a central component of its foreign policy since the Jimmy Carter administration(1977-81). Carter, seeking to improve the international image of the U.S. in the aftermath of the Viet Nam War, criticized human rights abuses and the lack of political freedoms in various U.S.-allied dictatorships, including Chile and Nicaragua. Such criticisms were designed not only to enhance the reputation of the U.S. internationally but also to buttress and give credibility to its ongoing ideological warfare against the socialist world.     

Gunshot residue testing in suicides: Part II: Analysis by inductive coupled plasma-atomic emission spectrometry

Several different methods can be employed to test for gunshot residue (GSR) on a decedent's hands, including scanning electron microscopy with energy dispersive x-ray (SEM/EDX) and inductive coupled plasma-atomic emission spectrometry (ICP-AES). In part I of this 2-part series, GSR results performed by SEM/EDX in undisputed cases of suicidal handgun wounds were studied. In part II, the same population was studied, deceased persons with undisputed suicidal handgun wounds, but GSR testing was performed using ICP-AES. A total of 102 cases were studied and analyzed for caliber of weapon, proximity of wound, and the results of the GSR testing. This study found that 50% of cases where the deceased was known to have fired a handgun immediately prior to death had positive GSR results by ICP/AES, which did not differ from the results of GSR testing by SEM/EDX. Since only 50% of cases where the person is known to have fired a weapon were positive for GSR by either method, this test should not be relied upon to determine whether someone has discharged a firearm and is not useful as a determining factor of whether or not a wound is self-inflicted or non-self-inflicted. While a positive GSR result may be of use, a negative result is not helpful in the medical examiner setting as a negative result indicates that either a person fired a weapon prior to death or a person did not fire a weapon prior to death.     

Succession pattern of carrion-feeding insects in Paramo, Colombia

The minimum postmortem interval can be estimated based on knowledge of the pattern of insect succession on a corpse. To use this approach requires that we take into account the rates of insect development associated with particular climatological conditions of the region. This study is the first to look at insect succession on decomposing carcasses in the high altitude plains (Paramo) in Colombia, at 3035 m above sea level. Five stages of decomposition were designated with indicator species identified for each stage: Callíphora nigribasis at the fresh stage; Compsomyiops verena at the bloated stage; Compsomyiops boliviana during active decay; Stearibia nigriceps and Hydrotaea sp. during advanced decay and Leptocera sp. for dry remains. A succession table is presented for carrion-associated species of the region, which can be used for estimating time since death in similar areas. Compsomyiops boliviana is reported for the first time in Colombia.
