Cuba: From “Dollarization” to “Euroization” or “Peso Reconsolidation”?

Since its “depenalization” in 1993, the U.S. dollar has become possibly a more significant component of Cuba's money supply than the old peso. What are the alternatives? The euro seems inappropriate, given the inevitability of eventual normalization of relations with the United States. More advantageous would be to restore the Cuban peso, though this would involve unifying the bifurcated economic structure and the dual monetary and exchange rate systems. The Cuban government has yet to announce its plans. This study argues that an appropriate mix of exchange rate, monetary, fiscal, and income or wage and salary policies should support a rehabilitation of the Cuban peso.     

The distribution of shotgun pellets after ricochet from an intermediate target surface

This paper presents a geometrical model for the ricochet of shotgun pellets from an intermediate target surface. The model predicts that after ricochet the shotgun pellet pattern will be elongated in the direction parallel to the intermediate target surface, as has been found in empirical studies. This paper also shows that the angle of impact theta of a mass of shotgun pellets with a target surface can be calculated without significant error from the width W and the length L of the pellet pattern using the formula: sin theta= W/L.     

Labor Standards and Labor Market Flexibility in the Middle East: Free Trade and Freer Unions?

This paper examines how two, potentially opposing trends—pressure to adhere to international labor standards and movement toward greater labor market flexibility—have affected labor market characteristics in the Middle East. Focusing on 13 countries, the paper presents indices of de jure and de facto labor flexibility and standards in the region. The paper makes two main contributions. First, it develops a typology of post-independence Middle Eastern political economies based on oil dependence and political regime type (including oil monarchies, low-income republics, and low-income monarchies) to explain widely divergent sub-regional trends in labor flexibility and standards. Second, it argues that different actors have spurred changes in labor flexibility and standards in distinct sub-regional political economy groupings. In the low-income countries, the state and domestic business were most instrumental in driving increased flexibility, although unions were able to win concessions in countries where the political system permitted some voice for labor. In the oil monarchies, international pressure, particularly through negotiations over trade agreements with the USA, spurred a trend toward increased labor standards, while domestic programs to indigenize the workforce account for a trend toward decreased flexibility.     

Developmental Trajectories of Aggressive and Non-Aggressive Conduct Problems

Modeling the heterogeneous trajectories along which antisocial behaviordevelops in childhood and adolescence may contribute in important waysto understanding antecedents of offending in adult life. This paperexamines the development of aggressive and non-aggressive conduct problemsin the Great Smoky Mountains Study of Youth, a longitudinal study in thesoutheastern United States. Aggressive and non-aggressive conduct problemsof clinical severity, police contact and arrest, and family andenvironmental correlates were assessed in four annual interviews for789 boys and 630 girls aged 9–13 at first interview. The bestfitting latent class model identified three developmental trajectories:stable low problem levels, stable high problem levels, and declining levelsof conduct problems, for both aggressive and non-aggressive behaviors. Boyswere over-represented in the stable high trajectory class on the aggressivetrajectory, but sex differences in non-aggressive trajectories were lessmarked. The overlap between aggressive and non-aggressive trajectory classeswas quite limited. Both classifications showed strong associations withrisks of police contact and arrest in early adolescence, and with measuresof family adversity. The results are discussed in relation to developmentalmodels of conduct disorder and delinquency.     

Micropolitics and Collective Liberation: Mind/Body Practice and Left Social Movements

This article explores the growing use of mind/body practices such as meditation and yoga in Left social movements. The analysis is rooted in interviews with activists participating in the transformative movement-building current: the growing number of organizations integrating subjective and social transformation practices. William Connolly’s work on micropolitics is put into conversation with the transformative movement-building current. The epistemological assumption undergirding this article is that textual political theory, and the knowledge being produced by activists, can benefit from dynamic exchange. My argument is that Connolly’s post-Nietzschean political theory offers a powerful justification for the political importance of mind/body practices, one that adds to activist justifications. I also argue that transformative movement-building contributes to recent theoretical debates by concretely demonstrating the integral importance of micropolitics for successful macromovements.
