Target Hardening and Terrorist Signaling: The Case of Aviation Security

In this article, we examine the relationship between hardening a target and the value that a terrorist group derives from attacking it. We use a simple expected value framework to compare how the expected value of attacking a hardened target varies between a violence-based approach, where terrorists are presumed to be maximizing the physical damage done to the target, and a signaling-based approach, where terrorists are presumed to be maximizing the symbolic value of their attack. We argue that, if it is proper to understand terrorist attacks as costly signals of terrorist strength or determination, hardening a target actually increases the expected value of attacking a target (relative to its value before hardening), even if the attack fails. We go on to examine the evolution of aviation security, and trace how al-Qaeda's views of airplanes and airports as targets have changed since 9/11. As aviation targets were hardened with increasingly onerous security measures, al-Qaeda began to see even attacks that did not result in detonation as successes, in large part because of what they signaled about al-Qaeda's abilities, and the ability of al-Qaeda to impose costs on the U.S. and other countries even in the absence of explosions.     

The bounds of smart decline: a foundational theory for planning shrinking cities

Economic decline has led to a new wave of population decline throughout the US, meaning more and more cities are shrinking. Growing interest in using smart decline principles to respond to shrinkage has been met with controversy in cities such as Detroit and Cleveland. This paper advances a foundational theory of smart decline that takes as its starting point discussions of ethics, equity, and social justice in the planning and political theory literature, but is well grounded in observations of successful smart decline practice.     

International Comparison of Public and Private Employees’ Work Motives,Attitudes, and Perceived Rewards

This article presents a conceptual perspective on the distinctive characteristics of public organizations and their personnel. This perspective leads to hypotheses that public organizations deliver distinctive goods and services that influence the motives and rewards for their employees. These hypotheses are tested with evidence from the International Social Survey Programme in order to compare public and private employees in 30 nations. Public employees in 28 of the 30 nations expressed higher levels of public‐service‐oriented motives. In all of the countries, public employees were more likely to say they receive rewards in the form of perceived social impact. In most of the countries, public employees placed less importance on high income as a reward and expressed higher levels of organizational commitment.

Practitioner Points

• The findings presented here add to previous evidence that public employees seek and attain more altruistic and public‐service‐oriented rewards than private sector employees. In particular, we add evidence that these differences hold in many different nations and cultural contexts.
• Compensation and incentive system reforms in many governments have often concentrated on financial incentives and streamlining procedures for discipline and removal. Such matters are important but should not drive out concerns with showing public employees the impact of their work on the well‐being of others and on the community and society. Leaders and managers should invest in incentive systems that emphasize such motives and rewards.
• Leaders and managers should invest in the use of altruistic and socially beneficial motives and rewards in recruiting systems.

     

Shared Race/Ethnicity,Court Procedural Justice,and Self‐Regulating Beliefs: A Study of Female Offenders

Using survey data from a sample of white, black, and Hispanic incarcerated females (N = 554), we examine if the theoretically hypothesized and empirically demonstrated relationship between procedural justice and obligation to obey the law is substantiated among a sample of offenders and explore the impact that sharing the race/ethnicity of the defense attorney and prosecutor in their most recent conviction has on female inmates' perceptions of court procedural justice and their perceived obligation to obey the law. The findings reveal that female offenders who perceive the courts as more procedurally just report a significantly greater obligation to obey the law. In addition, white female inmates who had a white prosecutor were significantly more likely to perceive the courts as procedurally just. Non‐whites, though, perceive the courts as more fair if they encountered a minority prosecutor regardless of whether the prosecutor was black or Hispanic.     

Evaluating Simulant Materials for Understanding Cranial Backspatter from a Ballistic Projectile

In cranial wounds resulting from a gunshot, the study of backspatter patterns can provide information about the actual incidents by linking material to surrounding objects. This study investigates the physics of backspatter from a high‐speed projectile impact and evaluates a range of simulant materials using impact tests. Next, we evaluate a mesh‐free method called smoothed particle hydrodynamics (SPH) to model the splashing mechanism during backspatter. The study has shown that a projectile impact causes fragmentation at the impact site, while transferring momentum to fragmented particles. The particles travel along the path of least resistance, leading to partial material movement in the reverse direction of the projectile motion causing backspatter. Medium‐density fiberboard is a better simulant for a human skull than polycarbonate, and lorica leather is a better simulant for a human skin than natural rubber. SPH is an effective numerical method for modeling the high‐speed impact fracture and fragmentations.     

Back in Style

In recent years Duncan Kennedy has turned to the question, what is Contemporary Legal Thought? For the most part, his answers have focused on the modes of legal argument he believes are indigenous to Contemporary Legal Thought in the United States, and possibly, at a transnational or global level as well. In this article, I bracket the question of content and ask instead, if we are interested in exploring the category of a legal ‘contemporary’, how do we do so? What historiographic methods are well-suited to the task of constituting ‘Contemporary Legal Thought’? My focus here is entirely on legal structuralism, the historical method I associate with Kennedy’s work beginning in the 1970s. By the mid-1980s, legal structuralism was under assault and quickly fading from the repertoire of available styles of doing history on the left. By the turn of the century, legal structuralism appeared to have vanished. I think that this was regrettable and unnecessary, and in this article I argue for a return to structuralist historiography. I do not pretend, however, that this return entails a second coming of the totalizing, originary center. Rather, I encourage thinking about legal structuralism in the way that I understand Roland Barthes, Hayden White, and to a large extent Duncan Kennedy himself to have thought about it: as a style. And as a style, legal structuralism is worth reawakening, a style back in style once more.
