Russia Resurgent,Russophobia in Decline? Polish Perceptions of Relations with the Russian Federation 2004–2012

How accurate is it to speak of a Polish russophobia today? The historic view of Poland as the easternmost bulwark of Western Christianity has involved an ‘othering’ of Russia that may be less salient following Poland's membership in the European Union. Elite and citizen attitudes towards Russia since 2004 are analysed and, in particular, the impact of the nationalistic policies of the Kaczyńskis promoted between 2005 and 2007 is assessed. Data indicate that Poles' attitudes have shifted from a fear of foreigners, including Russians, in part because of an increased sense of collective security, in part because of newfound economic confidence. The 2010 Smolensk air disaster that resulted in the deaths of many Polish leaders has been a valence issue in Polish domestic politics, but has generally advantaged politicians opposed to fanning fears of Russia. Since 2007, the two Tusk-led governments have registered Poles' mixed attitudes towards Russia more faithfully than the Kaczyńskis' leadership did. This has served as the basis for engaging in more cooperative foreign relations with Russia.     

Is there still collusion in the Dutch waste collection market?

Concentration indexes based on regional markets show that the Dutch market for refuse collection is highly concentrated in 2002 and 2010. Similar to earlier work in 2007, the results indicate some evidence that high concentration increases costs and therefore (partly) offsets the advantage of contracting out. In 2002, results with respect to concentration are somewhat less robust. In 2010, the cost-advantage effect of private provision becomes smaller. However, for this year, we have a stronger indication that the cost advantage of private provision depends negatively on regional concentration measured by the Hirschman–Herfindahl Index.     

Responsibility Attribution for Collective Decision Makers

We argue that individuals use responsibility attribution heuristics that apply to collective decisions made, for example, by families, teams within firms, boards in international organizations, or coalition governments. We conduct laboratory and online experiments to tease out the heuristics subjects use in their responsibility attribution for collective decision makers. The lab experiments comprise a collective dictator game in which decision makers have weighted votes and recipients can punish individual decision makers. Our results show that recipients punish unfair allocations and mainly target the decision maker with proposal power and with the largest vote share. We find weak evidence that decision makers with veto power are targeted or that recipients punish proportional to vote share. The online experiment demonstrates that subjects indeed believe that the decision maker with proposal power has the most influence on the collective decision outcome. We discuss the implications of our findings for theories of vote choice.     

Applying Insights from Transaction Cost Economics to Improve Cost Estimates for Public Sector Purchases: The Case of U.S. Military Acquisition

ABSTRACT

This article uses Transaction Cost Economics (TCE) to help characterize, explain, and ultimately reduce the cost growth that plagues many of today's major investments in military capabilities. There is mounting evidence of a systematic bias in initial cost estimates of new weapon systems purchased by the U.S. military. Unrealistically low cost estimates result in cost overruns. Fixing cost overruns can substantially impact public budgets and military readiness. Cost estimates serve a dual function: first, as an integral part of the decision-making process to evaluate military purchases/investments, and second, as a baseline for future defense budgets. In the first case, underestimating costs can result in too many new weapon program starts and excessive investments in those systems. In the second case, unrealistically low cost estimates result in overly optimistic budgets. Budgets planned on the basis of optimistic cost estimates create the illusion of more resources available than actually exist. Two factors are often blamed for unrealistically low cost estimates: bad incentives (psychological and political-economic explanations), and bad forecasts (methodological explanations). While briefly exploring the former, the focus of this study is on cost estimating methodology. Conventional public cost estimating techniques focus on the production costs of public purchases (input costs, learning curves, economies of scale and scope, etc.). The goal of this article is to improve cost estimates by expanding conventional cost estimating methodology to include TCE considerations. The primary insight of TCE is that correctly forecasting economic production costs of government purchases or acquisitions is necessary, but not sufficient. TCE emphasizes another set of costs—coordination and motivation costs (search and information costs; decision, contracting, and incentive costs; measurement, monitoring, and enforcement costs, etc.). This study encourages public officials and cost analysts to capture these costs and to understand key characteristics of public-private transactions (uncertainty, complexity, frequency, asset specificity, and market contestability) to generate more complete and reliable cost estimates and improve public sector purchases.     

Differentiation of blue ballpoint pen inks by laser desorption ionization mass spectrometry and high-performance thin-layer chromatography

The differentiation of inks on a questioned document can highlight a fraudulent insertion and is usually carried out by optical comparison and thin-layer chromatography (TLC). Laser desorption ionization mass spectrometry (LDI-MS) may also be used for the analysis of dyes from ink. This analytical technique was compared with a standard method of high-performance TLC (HPTLC) according to their capacity to differentiate blue ballpoint inks. Ink entries on paper from 31 blue ballpoint pens have been analyzed and their dye ink formulations compared. The pens were classified into 26 classes by LDI-MS against 18 for HPTLC. LDI-MS proved to be a more powerful method for differentiating ink formulations because it provides information about dye structures (molecular weights) and relative quantification of dye classes (peak areas). Sample preparation was minimal and analysis time was short in contrast to the more complex extraction, application, and development steps of the HPTLC method. However, only basic dyes and pigments were identified using positive mode LDI-MS, while HPTLC did yield additional information about acid dyes.     

Can the direct cardiac effects of the electric pulses generated by the TASER X26 cause immediate or delayed sudden cardiac arrest in normal adults?

There is only a small amount of experimental data about whether the TASER X26, a nonlethal weapon that delivers a series of brief electrical pulses to cause involuntary muscular contraction to temporarily incapacitate an individual, can initiate ventricular fibrillation to cause sudden cardiac arrest either immediately or sometime after its use. Therefore, this paper uses the fundamental law of electrostimulation and experimental data from the literature to estimate the likelihood of such events. Because of the short duration of the TASER pulses, the large duration of the cardiac cell membrane time constant, the small fraction of current from electrodes on the body surface that passes through the heart, and the resultant high pacing threshold from the body surface, the fundamental law of electrostimulation predicts that the TASER pulses will not stimulate an ectopic beat in the large majority of normal adults. Since the immediate initiation of ventricular fibrillation in a normal heart requires a very premature stimulated ectopic beat and the threshold for such premature beats is higher than less premature beats, it is unlikely that TASER pulses can immediately initiate ventricular fibrillation in such individuals through the direct effect of the electric field generated through the heart by the TASER. In the absence of preexisting heart disease, the delayed development of ventricular fibrillation requires the electrical stimuli to cause electroporation or myocardial necrosis. However, the electrical thresholds for electroporation and necrosis are many times higher than that required to stimulate an ectopic beat. Therefore, it is highly unlikely that the TASER X26 can cause ventricular fibrillation minutes to hours after its use through direct cardiac effects of the electric field generated by the TASER.
