Collegial Influence and Judicial Voting Change: The Effect of Membership Change on U.S. Supreme Court Justices

Understanding the source of voting changes by appellate judges provides an important window into the factors that shape the votes of the judges more generally. We argue that membership changes, by altering the collegial context in which judges make their choices, affect the information environment, long-term collegial considerations, and short-term strategic calculations. As a result, membership change should lead to greater uncertainty and more frequent voting changes among continuing justices in the term following a replacement. We test this proposition by looking at vote change by justices of the U.S. Supreme Court in two separate analyses: justices' votes on search-and-seizure cases since Mapp v. Ohio (1961) and on the progeny of Miranda v. Arizona (1966) . Our results support the argument that the collegial context helps explain changes in voting choices. Our analysis suggests that collegial considerations are an important component of judges' behavior and merit further evaluation in a cross-national context.     

The tension between empathy and assertiveness

This article explores two central dimensions of negotiation behavior: empathy and assertiveness. Empathy refers to the process by which negotiators demonstrate an understanding of their counterpart. Assertiveness refers to the process by which a negotiator articulates and advocates her interests. Although many people experience empathy to be incompatible with assertion and vice-versa, the authors suggest that the most effective negotiators develop expertise along both dimensions. Robert H.

The Process-Outcome Connection in Foreign Policy Decision Making: A Quantitative Study Building on Groupthink

This article investigates whether certain factors pertaining to the process of foreign policy decision making have a measurable, qualitative effect on foreign policy outcomes . The research is grounded in the groupthink literature but incorporates different dimensions of similar underlying notions from other international relations areas as well. Three different types of process factors are investigated: situational factors, such as stress and time constraints; factors associated with the structure of the group; and information processing factors. We test the influence of these factors on two types of outcomes—a decision's effect on national interests and its effect on the level of international conflict. We investigate this link in 31 cases of decision from 1975 through 1993. Scores for the outcome variables are based on survey responses from 21 foreign policy experts. For the process variables, we develop sets of operational definitions and then code each case based on extensive reading of case-study materials. OLS regression models are used to assess the hypotheses. We find that situation variables matter very little in terms of affecting outcomes and quality of information processing. On the other hand, both group structural factors and information processing are significantly related to outcomes in terms of national interests and level of international conflict.     

On the Role of Process Forensics in the Characterization of Fugitive Gasoline

The need to determine the source(s) of fugitive gasoline in the environment is common when multiple candidate sources co-exist nearby to the discovery or when gasoline is discovered subsequent to a property transfer. Process forensics is the component of environmental forensics that relies upon a detailed understanding of the current and historic refining and engineering practices and how these practices would predictably have affected the chemical composition of the automotive gasoline manufactured at different refineries at different times. Since not all gasoline is ‘created equal’, when the detailed “chemical fingerprint” of a fugitive gasoline in the environment is interpreted in light of process forensics, a more thorough understanding of the production practices used to refine the fugitive gasoline can emerge. In some circumstances this knowledge can help to implicate a particular source(s) of the gasoline.     

Gun violence and police problem solving: A research note examining alternative data sources

This article uses gun seizure data from the gun lab of the St. Louis Police Department to examine a problem-solving approach to seizing illegal firearms. Further, it explores narrative data from the police reports to understand the context surrounding 113 firearms seizure. The most important findings are that most illegal firearms are seized by the police department in the course of routine patrol, and that many seemingly nonviolent technical law violations (e.g., the unlawful carrying, use, or concealment of a firearm) often occur under violent circumstances. Given the paucity of gun research, future studies should use multiple data sources to further explain the gun/crime relationship. These findings are discussed in the context of routine policing.
