Affective Development from Middle Childhood to Late Adolescence: Trajectories of Mean-Level Change in Negative and Positive Affect

Journal of Youth and Adolescence - Adolescence has long been purported to be a period of emotional upheaval, yet relatively little is known regarding normative patterns of change in youth positive...     

Rational benevolence in small committees

We consider a game in which three committee members must divide up a benefit among themselves. In response to the large literature on sequential procedures in this type of game, we propose an institution that is inspired by auction theory. The (sealed) bids of the players are proposals for a distribution of the benefit and are given simultaneously. If any of the bids is preferred to all others in a pairwise comparison (i.e., a Condorcet winner exists) then this proposal is implemented. If such a bid does not exist then an equal split of the benefit is assumed. An equilibrium of this game is for each player to suggest that one of the opponents should receive the lion’s share of the benefit, even though each player cares only about his own share. We call this phenomenon “rational benevolence”. Although the end that is desired by the players is purely egoistic, the means of achieving it may be perceived as benevolent. Several applications of the game are suggested.     

Locating Supreme Court Opinions in Doctrine Space

We develop a scaling model to estimate U.S. Supreme Court opinion locations and justice ideal points along a common spatial dimension using data derived from the citations between opinions. Citations from new opinions to precedent opinions usually apply and endorse the doctrine of the precedent opinion; however, sometimes they implicitly or explicitly dispute the precedent opinion. We collect original datasets classifying citations from search and seizure and freedom of religion opinions written between 1953 and 2006 into these different types and develop a model relating the similarity of the doctrine embodied in the citing and cited opinions to the relative probability of these different types of citations. The resulting spatial estimates of opinion location are used to evaluate theories of Supreme Court bargaining and opinion writing. We find empirical support for theoretical models that predict the majority opinion will fall at the ideal point of the median member of the majority coalition. Given the centrality of theories of judicial policymaking to various substantive problems in political science, the method of scaling opinions developed in this article can facilitate a range of future research.     

The role of committee systems in post-communist legislatures: a case study of the Lithuanian Seimas

European parliamentary committee systems play an important role in organising the work of legislatures so as to assure the parliamentary leadership of its agenda. At the same time, the strategic positioning of committees in the legislative process provides opportunities for chairs to potentially undo the will of the leadership. We consider the degree to which committees in the Lithuanian legislature serve the private interests of legislators or those of the parliamentary leadership. We argue that while committees most often assist the leadership in obtaining preferred legislative outcomes, chairs on occasion have been able to change proposals or even frustrate the parliamentary leadership of governing coalitions.     

Multiple deaths resulting from shipboard exposure to trichlorotrifluoroethane

During the course of dockside ship maintenance, a compartment was partially flooded with tricholotrifluoroethane gas. One sailor entered the compartment, collapsed, and was then rescued by two other men. All three victims then climbed a 11-m (36-ft) ladder and collapsed. They all experienced a rapid development of cardiac arrest. We report on the pathologic, toxicologic, and pathophysiologic aspects of the incident.     

Risky Inference: Unobserved Treatment Effects in Conflict Studies

This article illustrates the importance of testing empirical models in samples appropriate to the theories the models are intended to test. While social science appears to mandate that we prefer general theories to limited ones, the generality of a theory rests in its logical application to a set of observations, not solely to its statistical survival in a large data set. Theories in international relations, especially those linking domestic turmoil and international conflict, are advancing, but are sometimes applied to samples larger than the related theories indicate. This paper examines the statistical consequences of estimation in overexpansive samples with unmodeled treatment effects; we argue that samples containing cases that cannot experience the causal phenomenon in question produce unmodeled treatment effects, and we reexamine three published articles whose samples are perhaps broader than their theories suggest they should be. The empirical analyses demonstrate that overexpansive samples can produce somewhat misleading results: the new models produce interesting findings that emerge as treatment effects are identified.
