Piercing the surface: A mechanical analysis of stabbing with household tools

Estimating the applied power during a stabbing incident, or estimating the minimal force necessary to penetrate the body with a certain weapon is a challenging task in forensic practice. A thorough forensic evaluation of stabbing forces needs objective numerical experimental data. Stabbing tests of 12 different weapons – including knives, a pair of scissors, a fork, screwdrivers, a rasp, a corkscrew, and a utility knife blade – were performed with a Mecmesin MultiTest-dV material tester on pork loin and ballistic gel to estimate the stabbing forces and dynamics. Penetration force (F_p) and maximal force (F_max) were recorded, and the registered force curves were analyzed. F_max was 159.8–212.07 Newton (N), 30.56–30.58 N, 168.9–185.48 N for various knives; 171.39–190.43 N for the pair of scissors, 233.6 N for the fork; 532.65–562.65 N, 370.31–367.19 N and 314.51–432.89 N for various screwdrivers, 44.14–56.62 N for utility knife during pork loin stabbing. The butter knife, corkscrew and rasp were not able to penetrate the pork loin, and the curved fork bent during stabbing. The results prove that weapon characteristics greatly influence the force necessary for penetration. Maximal stabbing force depends mostly on tip sharpness, and the force sharply decreases after penetration occurs, which indicates that edge sharpness is not as important as tip characteristics during stabbing perpendicular to skin surface. The penetration force during stabbing with a pair of scissors is comparable to the penetration force of knives. Stabbing with screwdrivers generally needs larger force than average knives but depends greatly on screwdriver size.     

Is anyone listening? Mass and elite opinion cueing in the EU

The paper analyses the connections between elite and mass opinion in the European Union. It considers both the ways in which mass publics use heuristics supplied by political elites to form their EU opinions, and the ways in which political elites respond to the opinions of the mass publics they represent. The paper employs data from simultaneously-conducted elite and mass surveys carried out in sixteen European countries in 2007. The results show that masses and elites in Europe do appear to take cues from one another in forming their EU opinions. Political elites base their individual-level opinions on the average position taken by their respective (national) party supporters. Mass respondents base their opinions on the average position taken by elite members of the (national) party with which they identify.     

Collateral times

Abstract

Today’s financial system essentially relies on the pledge of collateral. A closer look at this uniquely cross-disciplinary instrument not only reveals a remarkable absence in the modern disciplines but also a close relationship with money. This connection is brought into theoretical perspective by analysing the role of pledge in three historical configurations. In ancient Greece, symbola and horoi stones emerge as two distinct devices to secure contract that become entwined in seventeenth–eighteenth century pledge-theories of money as witness and object of exchange. Together these throw new light on the contemporary form of shadow money as a distinct marriage of security and safety.     

Responsiveness without Representation: Evidence from Minimum Wage Laws in U.S. States

How well does public policy represent mass preferences in U.S. states? Current approaches provide an incomplete account of statehouse democracy because they fail to compare preferences and policies on meaningful scales. Here, we overcome this problem by generating estimates of Americans' preferences on the minimum wage and compare them to observed policies both within and across states. Because we measure both preferences and policies on the same scale (U.S. dollars), we can quantify both the association of policy outcomes with preferences across states (responsiveness) and their deviation within states (bias). We demonstrate that while minimum wages respond to corresponding preferences across states, policy outcomes are more conservative than preferences in each state, with the average policy bias amounting to about two dollars. We also show that policy bias is substantially smaller in states with access to direct democratic institutions.     

Seeing the unseen: The Chernobyl imprint on the Hungarian public sphere

This research article analyzes the influence of the “Chernobyl factor” on the nuclear power discourse in Hungary. Despite its temporal distance, the geographical proximity of the Chernobyl disaster has significantly influenced the lives and perceptions of current Hungarian generations. The research examines two layers of public communication regarding the Chernobyl disaster—political discourse and Hungarian online news media—and matches these with the online representation of the catastrophe. This study finds that despite Chernobyl's significant impact on the cultural memory of Hungarian society, it is considered an event of the past with limited relevance for the future. The contemporary representation of Chernobyl reflects the aspirations and expectations of current society, manifests highly mediatized content, nurtures elements of infotainment, symbolizes danger and negligence, and socially reconstructs meaning through alienation from its original connotation. The Chernobyl factor does not appear significantly in current nuclear discourse in Hungary.     

Unpacking LogM: Toward a More General Theory of Party System Density

The standard model of political party system density combines two traditions to explain why some countries have more political parties than others, one tradition that emphasizes social cleavages and another that emphasizes electoral institutions, especially district magnitude. Despite its considerable success, there are several reasons to be less than fully satisfied with the standard model. We examine two of these problems associated with the scope of strategic voting and the functional form of the specification used to test the model. In doing so, we contrast the standard interpretation with an organizational ecology model that accounts for what the standard model did so well, but also accounts for important anomalies it ignores. We reexamine some of the key analyses that have been used to test the standard model to assess the severity of its limitations and the utility of the rival organizational ecology account.
