Where are we coming from? Are there any useful lessons from our administrative history?

Abstract: This article challenges the notion that contemporary conditions are so new that there are no useful lessons to be learned from administrative history. Beginning with the observation that many recent innovations in public organizations were foreshadowed under the United Canadas, 1841–1867, it asks why they were gradually abandoned over the first century of Confederation, only to be revived recently. For reasons of efficiency and democratic governance, the department became the keystone organization of Canadian public administration, and bureaucracy the key decision‐making technology. Changes in economic conditions, technology, élite ideology and political culture led to the introduction of public management as an alternative to bureaucracy. Neither form has met all the needs of politicians, public servants and citizens. One lesson of the past is that other values, like representativeness, will assert themselves with the result that the system will continue to evolve. Sommaire: Cet article conteste la notion voulant que les conditions contemporaines sont si nouvelles qu'il n'y a pas de leçon utile à chercher dans I'histoire administrative. Partant de I'observation que plusieurs innovations récentes en organisation publique avaient leur pendant sous les Canadas Unis, 1841–1867, I'article cherche à comprendre pourquoi celles‐ci furent graduellement abandonnées pendant le premier siècle de la Confédération puis redécouvertes récemment. Pour des raisons d'efficience et de gouveme démocratique, le ministère devint I'organisation de préférence au sein de I'administration publique canadienne, tandis que la bureaucratie devint le mode décisionnel préféré. Des changements aux conditions économiques, à la technologie, à I'idélogie des élites et à la culture politique ont menéà I'introdudion du management public comme alternative à la bureaucratie. Aucun de ces changements n'a satisfait tous les besoins des politiciens, des fonctionnaires et des citoyens. Le passé suggère que d'autres valeurs, telle la représentativité, vont s'imposer, poussant le système àévoluer encore.     

Results of the 2018 Rapid DNA Maturity Assessment

Three commercially available integrated rapid DNA instruments were tested as a part of a rapid DNA maturity assessment in July of 2018. The assessment was conducted with sets of blinded single-source reference samples provided to participants for testing on the individual rapid platforms within their laboratories. The data were returned to the National Institute of Standards and Technology (NIST) for review and analysis. Both FBI-defined automated review (Rapid DNA Analysis) and manual review (Modified Rapid DNA Analysis) of the datasets were conducted to assess the success of genotyping the 20 Combined DNA Index System (CODIS) core STR loci and full profiles generated by the instruments. Genotype results from the multiple platforms, participating laboratories, and STR typing chemistries were combined into a single analysis. The Rapid DNA Analysis resulted in a success rate of 80% for full profiles (85% for the 20 CODIS core loci) with automated analysis. Modified Rapid DNA Analysis resulted in a success rate of 90% for both the CODIS 20 core loci and full profiles (all attempted loci per chemistry). An analysis of the peak height ratios demonstrated that 95% of all heterozygous alleles were above 59% heterozygote balance. For base-pair sizing precision, the precision was below the standard 0.5 bp deviation for both the ANDE 6C System and the RapidHIT 200.     

Unusual Elevator-Related Deaths: A Report of Two Cases

We present two cases of elevator-related deaths that occurred in two different elevators, and deaths were caused by a similar, but unusual, mechanism. An elevator is a platform or compartment housed in a shaft for raising and lowering people or things to different levels. Elevator-related deaths and injuries are rarely reported in the literature. In most of these cases, cause of death was attributed to falls. It seems that most of the elevator accidents may be attributed to factors related to device maintenance inadequacies or even to device malfunctioning. In our cases, both elevator cars were not equipped with full-length inner doors, thus allowing both accidents to occur. Since 2014, the European Union adopted a relative directive, which imposes the need to equip all elevators with such full-length doors. The enforcement of the above-mentioned EU Directive is crucial, in order to prevent similar accidents in the future.     

Differentiation of Antemortem and Postmortem Appendicular Fractures Using Magnetic Resonance Imaging Signal Intensity Changes in Bone and Soft Tissues,

Intraosseous T1-weighted (T1W) and short-tau inversion recovery (STIR) magnetic resonance imaging (MRI) signal intensity changes—so-called bone marrow edema—may be able to differentiate antemortem and postmortem fractures in human forensic imaging. The primary objective of this study was to investigate this hypothesis using an animal model. Three juvenile Landrace pigs were anesthetized and underwent MRI of both tibiae and both radii using a 1.5 T magnet. T1W, T2-weighted (T2W), STIR, and T2* sequences were included. Antemortem fractures were induced in both tibiae and postmortem fractures in both radii, and MRI was repeated. Two board-certified radiologists blinded to fracture group jointly evaluated the images for intraosseous and soft tissue signal intensity changes. Sensitivity (Se) and specificity (Sp) in identifying antemortem fractures were calculated based on intraosseous, soft tissue, and combined intraosseous and soft tissue signal intensity changes. Intraosseous and soft tissue signal intensity changes, when present, were hyperintense in all sequences. Intraosseous hyperintensity in T1W and T2W sequences yielded Sp of 100% for antemortem fractures. Regardless of sequence, soft tissue hyperintensity was comparatively more sensitive than intraosseous hyperintensity. Sensitivity for each sequence could be maximized by assessment of soft tissue and intraosseous hyperintense signals together; for the T1W sequence, such assessment optimized diagnostic utility yielding a Se of 100% and Sp of 83%. In summary, MRI—particularly the T1W sequence—can differentiate antemortem and postmortem fractures and may be a useful adjunct to the forensic analyses of fractures.     

Decentralization and citizen trust: An empirical study of policing in more and less developed countries

Decentralization is argued to enhance citizen–government relationships and, thus, to lead to higher levels of citizen trust. General purpose policing encompasses various services that might be assigned to different levels of governments. The literature lacks generalizable studies of the effects of the structural arrangements of police systems on police performance. This study is a cross‐national exploration of the relationship between the varying degrees of police decentralization and police performance as measured by citizen trust in the police. It uses a measure of decentralization of police systems based on the tiers of government with some control over police. Results show that, in the 72 sample countries, the relationship between citizen trust in police and decentralized police systems is not statistically significant. However, when the countries are categorized by the Human Development Index, decentralized police systems tend to be positively related to citizen trust in the more developed countries but inversely in the less developed countries.     

Why did the United States Invade Iraq in 2003?

Why did the United States invade Iraq in 2003? Most scholars cite the nonproliferation of weapons of mass destruction (WMD), a neoconservative desire to spread democracy, or the placating of domestic interest groups as the Bush administration’s objectives, but I suggest these arguments are flawed. Instead, I proffer the “performative war” thesis resting on the concepts of status, reputation, and hierarchy to explain the Iraq war. Hegemons desire generalized deterrence, such that others do not challenge their territory, preferences, or rule. However, the challenging of a hegemon’s authority—as occurred on 9/11—generates a need to assert hegemony and demonstrate strength to a global audience. Only fighting a war can demonstrate such strength; no peaceful bargain, even a lopsided one, can achieve the same effect. Consistent with this framework, the United States fought Iraq mainly for its demonstration effect—defeating the recalcitrant Saddam would lead other states to fear the United States and submit to its authority and global order.
