A spatial analysis of candidate competition in dual member districts: The 1989 Chilean senatorial elections

This study uses empirical spatial theory to evaluate candidate and voter behavior in senate elections contested during the 1989 Chilean general election. The study evaluates whether senatorial candidates competing in dual member districts under Chilean d'Hondt locate near the periphery or interior of the electoral space. Spatial analyses demonstrate the Chilean senatorial electoral system is characterized by centrifugal forces. In particular, candidates of the right locate on the periphery of the space and face few incentives to pursue moderate electoral strategies. The study also characterizes bases of party and candidate support and the underlying dimensions of political competition. Spatial analysis reveals both change and continuity in the pre- and post-authoritarian electoral universes.     

Directional and proximity models of voter choice in recent US presidential elections

This note evaluates relative ability of the proximity and recently proposed directional variants of the spatial model of voter choice to account for candidate evaluations in US presidential elections contested between 1980 and 1992. I do this by estimating a statistical model that represents voter preference for a candidate as a weighted average of proximity and directional components. The analysis corroborates previous studies supporting the directional model, but illustrate that these results are sensitive to statistical specification. Alternative methodological specifications favor a mixed directional-proximity model and the traditional distance representation.     

Gender Differences in Political Knowledge: Distinguishing Characteristics-Based and Returns-Based Differences

This study assesses whether gender-based differences in political knowledge primarily result from differences in observable attributes or from differences in returns for otherwise equivalent characteristics. It applies a statistical decomposition methodology to data obtained from the 1992–2004 American National Election Studies. There is a consistent 10-point gender gap in measured political knowledge, of which approximately one-third is due to gender-based differences in the characteristics that predict political knowledge, with the remaining two-thirds due to male–female differences in the returns to these characteristics. The methodology identifies the relative contribution of the predictors of political knowledge to each portion of the gap, and then uses this information to elucidate the underlying sources of the political knowledge gender gap and its prognosis. Education is the characteristic that most clearly enlarges the gap, with men receiving significantly larger returns to political knowledge from education than women. Group membership reduces the gap as women obtain gains in political knowledge from belonging to organizations that do not accrue to men. However, these gains are not sufficient to significantly reduce the gap.

Does democracy “suffer” from diversity? Issue representation and diversity in senate elections

Several recent studies examine the degree to which congressional behavior affects candidates’ electoral fortunes (e.g., Carson, 2005). Research examining electoral competitiveness (Bond, Campbell, & Cottrill, 2001; Koetzle, 1998) and roll call voting (Bailey & Brady, 1998; Jones, 2003) finds that diversity in the electorate mediates the impact of numerous variables upon election outcomes and representation. However, the influence of diversity on other modes of representation – such as the policy positions taken by Senate candidates–remains unexplored. We investigate the link between representation and Senate candidates’ policy positions and thereby examine the degree to which voter diversity affects candidates’ policy responsiveness. We find that diversity significantly influences responsiveness, both directly and indirectly – candidates in homogenous states are more responsive to constituents than are candidates in heterogeneous states.     

Voter Choice in the 1995 French Presidential Election

This study estimates a model of voter choice for the first and second ballots of the 1995 French Presidential election. Its objective is to characterize the relative importance of traditional bases of French voter choice such as social class relative to campaign issues and voter evaluations of the economy. The study also seeks to identify candidate-specific bases of voter choice. Multinomial logit analysis of voter choice among the four leading candidates reveals a stronger role for campaign issues than previous studies suggest. Voter-candidate ideological proximity is the strongest predictor of first and second ballot choice, followed by voter perceptions of candidate ability to address unemployment and political corruption. Demographic variables have limited explanatory power in both the first and second ballot models. The parameter estimates demonstrate considerable differences in the bases of voter choice across candidates, with the bases of voter choice for National Front leader Jean-Marie le Pen most distinct from those of the remaining candidates.     

The Ongoing Reforms to China's Government and State Sector: The case of the energy industry

Though the reforms announced by the Chinese government in the spring of 1998 appear to be substantial and wide ranging, by themselves they may have little impact either on the effectiveness of government or on the performance of the state industries. Two outstanding problems are the structure and allocation of responsibilities within the government, and the excessive power of the state companies. The tasks of regulation and policy formulation in the energy sector should be clearly allocated in a simple administrative structure which specifically excludes any role for the state companies. The present structure of the state-owned energy industries is such that these companies have a great deal of power, not only in the market but also with respect to the government.     

Complex Congenital Heart Malformation Including Transposition of the Great Vessels,Presenting as Sudden Unexplained Infant Death

Transposition of the great vessels (TGV) is a common congenital heart defect that is difficult to diagnose before birth. Antenatal diagnosis is associated with increased survival. Unusual features such as anomalous pulmonary artery origin may delay cyanosis, decreasing clinical suspicion. A three‐week old female infant who had never been cyanotic presented for forensic autopsy due to onset of unresponsiveness at home. History included risk factors for TGV and signs of heart enlargement that were not recognized during life. Cardiac pathology consultation identified D‐type TGV with additional rare anomalies. TGV may present as sudden unexplained infant death (SUID) for forensic autopsy if variant features prevent development of cyanosis. Cardiac pathology consultation is helpful in clarifying these features.
