Discourses of empire: the US ‘empire’, globalisation and international relations

The contemporary normalisation of discussing United States foreign policy in terms of imperialism and empire is of great interest to all scholars of international relations, and the purpose of the present article is to analyse this trend in terms of the broader context of the role of empire in international relations theorising. There is a deeper logic to the recognition of a truly imperial republic than just contemporary foreign policy, as the US as empire seems to convey a richer understanding and a deeper resonance of America's contemporary role. What is also striking are the ties between empire and globalisation, which are increasingly being recognised. The use of imperial language as a more general discourse questions the dominant assumptions in international relations concerning the state of anarchy in the international system, without abandoning the dynamics of power and coercion that are part and parcel of imperial relationships, which can help to convey a richer sense of the dynamics of the international realm.     

Sources of Leader Support and Interstate Rivalry

Since segments of the selectorate differently experience costs and benefits from rivalry, the foreign policy choices of leaders reflect these domestic preferences. As a result, shifts in the composition of the domestic coalition of support backing the leader provide a fundamental determinant of rivalry termination. While previous research sought to explore the relationship between domestic political turnover and rivalry termination using regime transitions as a proxy for turnover of the state’s domestic ruling group, in practice this measure exhibits significant disconnection with the quantity of interest. Further, there are alternative pathways through which regime transitions may lead to rivalry termination. I test the relationship using new data from the CHISOLS project, finding that when rivals undergo a change in the source of support that maintains the leader in office, the probability of rivalry termination rises dramatically. I further find that regime transitions have an effect on the probability of rivalry termination that is independent of the effect of ruling coalition turnover. This study thus both asserts the relationship between domestic political turnover and rivalry termination and clarifies the mechanism by which the relationship operates.     

Using social network analysis to target criminal networks

Using social network analysis (SNA), we propose a model for targeting criminal networks. The model we present here is a revised version of our existing model (Schwartz and Rouselle in IALEIA Journal, 18(1):18–14, 2008), which itself builds on Steve Borgatti’s SNA-based key player approach. Whereas Borgatti’s approach focuses solely on actors’ network positions, our model also incorporates the relative strength or potency of actors, as well as the strength of the relationships binding network actors.

The Effect of Skin Debris on Gunshot Residue Sampling and Detection

These experiments were designed to determine whether skin debris (desquamated epithelial cells and apparent skin oils) affects gunshot residue (GSR) particle detection on the sticky tape lift samples prepared for scanning electron microscopy (SEM). A dabbing experiment showed that GSR particles accumulate not only on the adhesive surface of the sampler, but also on the epithelial cell surfaces. Samplers were loaded with target GSR followed by dabbing 30 times on the back of a hand. Backscatter electron images were taken at 20 kV and for some at 30 kV of the same areas. The samplers were then treated with a sodium/calcium hypochlorite solution (bleach) to remove skin debris and again imaged in the SEM. Comparison of these images shows more GSR particles will likely be revealed at 30 kV than 20 kV and more particles revealed by the bleach treatment in an automated SEM system.     

Recovery of DNA and fingerprints from touched documents

This study investigated the various factors affecting DNA profiling from DNA recovered from fingerprints deposited on paper before and after fingerprint enhancement treatments. The DNeasy^® plant mini kit (QIAGEN^®) was found to improve DNA recovery from paper by over 150% compared with the QIAamp^® mini kit. A significant decrease in the amount of DNA recovered was observed following treatment with DFO and/or Ninhydrin. This decrease in yield did not have a comparably significant effect on the quality of the SGM Plus™ profiles. Furthermore, this study found that whilst certain paper types, such as newspaper, magazine and filter paper allowed for the good recovery of DNA, common office paper and white card, strongly interfered with the recovery of DNA resulting in poor quality profiles.
