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.     

The rise of the Global South,the IMF and the future of Law and Development

Following the onset of the Asian Financial Crisis the world has witnessed a re-accommodation of the global financial system. In the particular case of middle-income countries they have disentangled themselves from the conditionality of the IMF and grown into more assertive actors in international forums, proposing new alternative mechanisms to become more financially independent and for the provision of development assistance. This article critically reviews the new reality by assessing the strategies deployed by developing countries to reduce the IMF’s influence, and explores the potential consequences of the rise of middle-income nations for Law and Development.     

International Co‐Authorship and Research Team Performance in Colombia

This article examines the ways in which International Scientific Collaboration, as observed by the co‐authorship of journal articles written by local scientists and partners located overseas, affects the ability of research teams to produce bibliographic outputs and to contribute to local knowledge. A sample of 672 teams was randomly selected for the analyses. In addition, 20 interviews with experts and team members were administered to discuss models and results. Results show that co‐authoring with partners located overseas increases team output by nearly 40% and by between three and five bibliographic products. It also shows that a team's odds of involving Colombia in its research process are 2.2 times larger for those co‐authoring with a partner located overseas than for those that do not. Theoretical and policy implications are discussed.     

Two concepts of desert

In the first section I briefly consider some stituations in which standard desert-claims would be disputed, with the aim of revealing why and by whom they are asserted or denied. Having attained some understanding of the point of different desert-statements, I propose an accound of their content that entails the thesis that statements of positive desert (deserving something desirable) sharply differ in meaning from statements of negative desert (deserving something undesirable), even when expressed in the same form. In the second section I use this ambiguity thesis to argue against an appealing way of defending Hegel's claim that a wrongdoer has a right to be punished and against Kant's defense of the view that there is a duty to punish those who deserve it. I also show how an understanding of negative desert that recognizes the ambiguity thesis enables us to defend the ordinary view of mercy against Kantian criticisms and to reject the popular misconception that mercy is necessarily at odds with justice. In the third section I use the ambiguity thesis to rebut the common claim (found in Mill and Aristotle, among others) that it is unjust for a person to have or be given mone benefits than she deserves. I conclude by showing how an understanding of positive desert that recognizes the ambiguity thesis leads to a rejection both of certain complaints against traditional systems of private property and also of certain moralistic scruples that might give pause to those who acknowledge the moral duty to assist the needy.     

Recent changes in the Mexican industrial labor force

"We study...some of the repercussions of the crisis and economic restructuring on the manufacturing labour force in the main urban areas of Mexico. Using the data of the National Survey of Urban Employment for the period 1986-1992, we set, first of all, the evolution of female and male presence in the manufacture of the country's main industrial cities. Further, some of the characteristics of the manufacturing labour force in different types of cities are examined. For this purpose, we are considering several issues: the condition of wage earner and non-wage earner workers, the size of the establishment, some sociodemographic aspects (gender, age, schooling level, and condition of the head of household), as well as different aspects related to labour conditions (length of workday, job benefits, and salary levels)."

Testing a Novel 3D Printed Radiographic Imaging Device for Use in Forensic Odontology

There are specific challenges related to forensic dental radiology and difficulties in aligning X‐ray equipment to teeth of interest. Researchers used 3D printing to create a new device, the combined holding and aiming device (CHAD), to address the positioning limitations of current dental X‐ray devices. Participants (N = 24) used the CHAD, soft dental wax, and a modified external aiming device (MEAD) to determine device preference, radiographer's efficiency, and technique errors. Each participant exposed six X‐rays per device for a total of 432 X‐rays scored. A significant difference was found at the 0.05 level between the three devices (p = 0.0015), with the MEAD having the least amount of total errors and soft dental wax taking the least amount of time. Total errors were highest when participants used soft dental wax—both the MEAD and the CHAD performed best overall. Further research in forensic dental radiology and use of holding devices is needed.     

Determining ease of access to arms methodology and coding

This paper aims to establish an initial determination of what the primary indicators of the ease of access to small arms and light weapons are. Guns are so abundant and ubiquitous in most parts of the world that the right question to ask is not how many guns are out there but what are the conditions, or lack thereof, that promote the ease of access. This paper also aims to offer researchers with initial tools for coding indicators for the ease of access in future investigations on this important topic. At the outset, I introduce three sets of indicators: legal, ‘black market feeder indicators’, and socialeconomic indicators.
