The American West’s longest large mammal migration: clarifying and securing the common interest

Over the last 10 years, conflict has grown over a 170-mile pronghorn antelope (Antilocapra americana) migration between Grand Teton National Park and the Upper Green River Basin in western Wyoming. Resolving conflict in the common interest is proving difficult. This movement is the longest mammal migration in the lower 48 states, spanning the jurisdiction of three federal agencies, three Wyoming counties, and over 40 private landowners. In addition, there are over ten non-governmental conservation organizations, two major state agencies, Wyoming’s executive office, and many citizens involved in the issue. There are three major problem definitions serving the beliefs of participants: the ecological-scientific (conservation biologists, environmentalists), local rights (local control, property rights), and cultural value (historic, western heritage) definitions. These definitions challenge the social and decision making processes of regional communities and government agencies. Underlying the problem of securing the common interest is the highly fragmented patterns of authority and control, misorganized arena(s), and parochial perspectives of many participants. Options promoted by participants can be loosely classified as top-down (government, expert driven) versus bottom-up (local, practice-based) approaches and reflect preferences for the distribution and uses of power and other values. Given the social and decision making context of this case, the bottom-up, practiced-based approach would likely best secure a common interest outcome.

Supplying Disadvantaged Schools with Effective Teachers: Experimental Evidence on Secondary Math Teachers from Teach For America

Teach For America (TFA) is an important but controversial source of teachers for hard‐to‐staff subjects in high‐poverty U.S. schools. We present findings from the first large‐scale experimental study of secondary math teachers from TFA. We find that TFA teachers are more effective than other math teachers in the same schools, increasing student math achievement by 0.07 standard deviations over one school year. Addressing concerns about the fact that TFA requires only a two‐year commitment, we find that TFA teachers in their first two years of teaching are more effective than more experienced non‐TFA teachers in the same schools.     

Extension of the portfolio allocation model to surplus majority governments: a fuzzy approach

Scholars have long studied the conditions under which the cabinet making process will result in minority, surplus majority, or minimum-winning governing coalitions in parliamentary systems. Since Riker, a good number of these attempts have been based on rational choice assumptions. Among formal approaches in this vein, Laver and Shepsle’s (Making and breaking governments: Cabinets and legislatures in parliamentary governments, 1996) portfolio allocation model argues that parties centrally located in policy space have a greater potential for being part of any governing coalition and that parties located at the issue-by-issue median have a high likelihood of forming a minority government. However, the model predicts that surplus majority coalitions will only form when the number of salient policy dimensions in the political system is greater than two. We incorporate fuzzy set theory in the portfolio allocation model, permitting us to model ambiguity in parties’ policy preferences. The reformulated model accounts for the formation of surplus majority coalitions in two-dimensional policy space. We illustrate the model’s conclusions with a case study of the 1996 surplus majority coalition in the Lithuanian Seimas.

AIDS prevention: legislative options

This article reviews legislative options to prevent the transmission of HIV infection. It distinguishes between pre-exposure measures designed to prevent initial exposure, and post-exposure measures aimed at preventing infected individuals from exposing others. Part I identifies education as the key component of a comprehensive prevention program, and reviews options for pre-exposure education programs designed to avoid or minimize exposure. Part II reviews post-exposure prevention measures, focusing on reporting and contact tracing provisions. Mandatory reporting by name of individuals testing HIV positive and mandatory contact tracing are opposed as counterproductive prevention measures; voluntary partner notification is supported. Part III examines various prevention efforts for settings where there may be either a real or perceived risk of transmission of HIV infection. Part IV sets out conclusions.
