Make or buy on the Russian railway? Coase,Williamson, and Tsar Nicholas II

There is a growing consensus among economists that the most procompetitive strategy for restructuring public utility enterprises includes complete vertical separation of the network or grid portion of a sector from other parts of the sector where competition is to be created. Although exceptions to this rule are readily granted, it is generally considered that any alternative strategy may pay a high cost in terms of discriminatory access to the grid by non-integrated entrants into the new competitive sector. This consensus is somewhat surprising in light of the simultaneous growth of transactions cost economics, with its emphasis on the benefits of close vertical relationships—including vertical integration—in the face of complexity, unforeseeable contingencies, and problems with contract law enforcement. These issues are considered in the context of a Russian railways restructuring plan which may, or may not, involve complete vertical separation.

COMPETITION IN FREIGHT RAILWAYS: "ABOVE-THE-RAIL" OPERATORS IN CENTRAL EUROPE AND RUSSIA

The railways of Russia and the Central and Eastern Europeancountries are in the process of restructuring. In most cases,the "vertical separation" reform model is being pursued, andreformers are seeking to introduce competition among freighttrain operators through the provision of "open access" to themonopoly infrastructure. This paper shows that, in two countries,Poland and Romania, a good deal of competition has been createdby the entry of new freight operators, many of them either largeshippers integrating upstream or former freight forwarders.However, in other countries, the incumbent freight operatorsretain virtually 100 percent of the market. In particular, Russiahas taken only the very first steps toward creating competitionin this sector, and new freight train operators face significantbarriers to competing with the incumbent.     

Validation of an LC–MS Method for the Detection and Quantification of BZP and TFMPP and their Hydroxylated Metabolites in Human Plasma and its Application to the Pharmacokinetic Study of TFMPP in Humans*

Abstract: An LC–MS method was developed for benzylpiperazine (BZP) and trifluoromethylphenylpiperazine (TFMPP), constituents of “party pills” or “legal herbal highs,” and their metabolites in human blood plasma. Compounds were resolved using a mixture of ammonium formate (pH 4.5, 0.01 M) and acetonitrile (flow rate of 1.0 mL/min) with a C18 column. Calibration curves were linear from 1 to 50 ng/mL (R² > 0.99); the lower limit of quantification (LLOQ) was 5 ng/mL; the accuracy was >90%; the intra‐ and interday relative standard deviations (R.S.D) were <5% and <10%, respectively. Human plasma concentrations of TFMPP were measured in blood samples taken from healthy adults (n = 6) over 24 h following a 60‐mg oral dose of TFMPP: these peaked at 24.10 ng/mL (±1.8 ng/mL) (C_max) after 90 min (T_max). Plasma concentrations of 1‐(3‐trifluoromethyl‐4‐hydroxyphenyl) piperazine peaked at 20.2 ng/mL (±4.6 ng/mL) after 90 min. TFMPP had two disposition phases (t_½ = 2.04 h (±0.19 h) and 5.95 h (±1.63 h). Apparent clearance (Cl/F) was 384 L/h (±45 L/h).     

The effect of mark enhancement techniques on the presumptive and confirmatory tests for blood

An investigation into the effects of physical and chemical enhancement on subsequent presumptive and confirmatory tests for human blood is presented. Human blood was deposited onto porous (white 80 gsm paper and brown envelope) and non-porous (tile and linoleum) substrates in a depletion series (30 depletions on non-porous and 20 on porous) and subjected to three ageing periods; 1, 7 and 28?days. A number of enhancement techniques were tested [fluorescence, black magnetic powder (BMP), iron-oxide black powder suspension (PS), cyanoacrylate (CA) fuming, acid violet 17 (AV17), acid yellow 7 (AY7), ninhydrin, DFO and Bluestar Forensic Magnum (BFM) luminol] to evaluate their potential effects on subsequent presumptive and confirmatory tests. AV17 and Bluestar provided the best enhancement and fully enhanced all depletions in the series. The sensitivity of the Kastle-Meyer (KM) (presumptive), Takayama and RSID-Blood tests (confirmatory) was initially investigated to determine the range of detectable depletions. The KM test detected all depletions, whereas the Takayama test detected up to depletion 6 and RSID-Blood detected up to depletion 20 (paper), 10 (envelope), 15 (tile) and 9 (lino). The abilities of these tests to detect blood after enhancement were then observed.A number of techniques resulted in little to no effect on any of the blood tests, whereas adverse effects were observed for others. Ninhydrin and CA fuming caused weak but instantaneous positive KM results whereas methanol-based AV17 and AY7 delayed the reaction by as much as 1?min. The Takayama test was not very sensitive, therefore, its performance was easily affected by enhancement and negative results were often observed. RSID-Blood tests were largely unaffected by chemical enhancement although a drop in positive results was observed for some of the techniques when compared to positive controls.Using a standard procedure for DNA extraction, all the tested blood samples (before and after enhancement) gave a detectable quantity of DNA and were successfully profiled. Out of the 45 samples processed for DNA profiling, 41 gave full profiles, while the remaining showed allele drop out in one or two loci.     

Identifying the origins of welsh local government reform

Although those within Welsh local government circles were aware that the Welsh Office was considering restructuring local government as early as December 1990, the first the general population knew of the proposed changes was in June 1991. It was in that month that the Welsh Secretary produced a consultation paper entitled The Structure of Local Government in Wales. ¹ This advocated the introduction of unitary authorities throughout Wales. The publication of this consultation paper was at the same time as those for Scotland² and England.³ This gave the impression that Wales was merely following events in England and Scotland. Such an assumption remains widespread. In the first part of his article ‘Legislating for Wales ‐ Local Government (Wales) Act 1994’ Paul Griffiths indicated that the local government changes in Wales were unplanned and perhaps unintended and a reaction to changes occurring in England.⁴ This article aims to shed more light on the background behind Welsh local government reform. It indicates that the changes in Welsh local government were more a matter of coincidence than merely a mirror of those happening elsewhere. It also argues that the changes in Wales have their own unique Welsh origins, and that the changes may well have occurred, regardless of what happened in the rest of the United Kingdom.     

American security policy and NATO's future

NATO remains the United States’ principal instrument for shaping the security environment in Europe. It acts as a long‐run hedge against a possible resurrected Russian threat to the continent and to dampen the prospects for the renationalization of military and security policies in Europe. The United States faces formidable challenges to ensure the viability of NATO after the Cold War. Washington must be prepared to engage in a grand balancing act on several fronts to perpetuate the Alliance. It must support NATO enlargement to move the Alliance's geopolitical center eastward, but not to territory that would practically indefensible in the event of a resurgent Russia. Out‐of‐area operations will preoccupy Alliance attention in the near‐future, but too great an appetite for undertaking peacekeeping missions might over time substantially erode the Alliance's ability to deter or withstand the political and military pressure from a resurgent Russia or major power or coalition on the outlying areas of the Eurasian landmass.     

The Spatial Distribution of Postblast RDX Residue: Forensic Implications

Locating exactly where trace explosive residue samples should be sought during sample collection at bomb scenes is not specified in the published literature or guidelines; in this area, it is generally acknowledged that forensic practices are based on tradition rather than evidence. This study investigated patterns in the spatial distribution of postblast 1,3,5‐trinitro‐1,3,5‐triazocyclohexane residue from a series of unconfined detonations, over a range of sampling sites, and at two different detonation heights. The amount of residue recovered from the sites decreased as a function of distance from the center of the explosion. [Correction added after online publication 27 December 2012: In the preceding sentence, “increased” was corrected to “decreased” to agree with the conclusion of the article.] As the height of the detonations increased, more residues were found from all sampling sites. The findings of this empirical study have a number of important practical implications including determining where residue samples are best sought at crime scenes.     

A New Method of Assessing Judicial Workload in Juvenile Dependency Cases

This article describes a new method for calculating judicial workload in dependency or child abuse and neglect cases. In contrast to traditional judicial workload methods, the method described herein produces estimates of judicial workload that take into account the complex role of the juvenile dependency court judge—a role that includes both on‐ and off‐the‐bench activities. The method provides workload estimates that give guidance to courts not only about the minimally sufficient judicial resources needed to accommodate current caseload needs, but also what level of judicial resources would be required to hold substantive dependency court hearings that comport with nationally recognized practice recommendations. The article reviews commonly used judicial workload methods, outlines the new method, and uses a pilot of the method as an example of how the method works in practice. Broader implications of this workload method are also discussed.
