Abstract: System trespassing, or unlawfully gaining access to a computer system, is a growing concern worldwide. Viewing system trespassing through a criminological lens, this study analyzes the effect of the presence of other users on the system on the trespassing incident. Drawing on principles of Situational Crime Prevention (SCP), Routine Activities Theory (RAT), and restrictive deterrence, this research examines the potential restrictive deterrent effects of natural and place manager surveillance. Data were collected from a randomized control trial of target computers deployed on the network of a large U.S. university. Using ANOVA and pairwise means comparisons, this study examines whether the number and type (administrative or non-administrative) of users present on a system reduces the number of times a system trespasser returns to the system and the average duration of the system trespassing events. Results indicate that the type of user (administrative) produced a restrictive deterrent effect by significantly reducing the number of times a trespasser returned to the system.

Abstract: Can computing environments deter system trespassers and increase intruders’ likelihood to cover their tracks during the progression of a system trespassing event? We suspect that with the incorporation ofthat incorporating social dimensions into the computer environment, and particularly surveillance and sanction threats, can answer this question affirmatively. the answer to this question could be affirmative. To generate sufficient empirical evidence to answer this questiontest our suspicions, we conducted a series of randomized field trials in the U.S. and China, using a large set of target computers built for the sole purpose of being infiltrated. We configured these computers to present varying levels of ambiguity regarding the presence of surveillance in the system, and investigated how this ambiguity influenced system trespassers’ likelihood to issue “clean tracks” commands. Findings indicate that the presence of unambiguous signs of surveillance increases the probability of clean tracksthese commands being entered on the system. Nevertheless, even when they are given clear signs of detection, we find that intruders are less likely to use clean tracks commands in the absence of subsequent presentations of sanction threats.

Abstract: Research on collective action shows that identity, shared grievances, and group efficacy motivate social protest. Although insightful, this work often overlooks the inhibiting—and potentially facilitating—effects of ideology on collective action support. We address these oversights by taking a system justification theory perspective and arguing that collective action support is ultimately based in ideology. Accordingly, we use nationally representative data to show that system justification motivation has a negative indirect effect on system-challenging collective action via reductions in group identification, perceptions of injustice, and resultant group- and system-based anger for a low-status group (N = 2,328), but positive indirect effects via the same mechanisms for a high-status group (N = 13,819). Conversely, system justification motivation is positively associated with system-supporting collective action for both groups. These results provide the first integration of ideology into models of collective action to explain when ideology will—and will not—promote social change.

Abstract: For a long time, electoral reforms in established democracies were rare, except in France. Since the early 1990s, however, they have been more frequent. Most of the time, these reforms were radical, making it difficult to analyze the effects of some main components of the electoral system, such as electoral formula, ballot structure, district magnitude, size of legislature and number of candidates/ parties.

From this angle, the 2004 French European electoral reform constitutes an exception since it changed only one main component by removing the single nationwide constituency and dividing the country into eight multi-seats constituencies, whereas the other main electoral elements still were identical. It is a perfect ‘before-and-after’ case-study, monitoring the impact of an electoral reform over successive elections within a particular country.

This paper points out mechanical effects of a decrease in the average district magnitude on the representation. At the national level, this change led to an increase in the nationwide deviation from proportionality, to a decrease in the effective number of parliamentary parties and to a rise of the break-even point. At the local level, that of the constituency, variations in district magnitude impacted the seats votes equation and the exclusion threshold. In 2004, larger parties have been advantaged by the electoral reform. So, the district magnitude is really the decisive factor. French electoral reform has undoubtedly exerted some mechanical effects but also psychological ones: at the local level, the effective number of electoral parties decreased as the district magnitude decreased. In other words, variations in district magnitude influenced the voters and modified their vote. This reminds us that there is a strategic vote in PR, like in first-past-the-post, even if the former situation is still less studied.
