Policy adoption in dynamic international environments: Evidence from national AIDS programs

The policy adoption is often seen as a function of internal determinants, external determinants, or a combination of the two. In the years since the start of the HIV/AIDS epidemic nearly every country in the world has adopted of some nature a program to combat the epidemic. This article demonstrates the mixed mechanisms influencing the adoption of AIDS programs, in a quantitative study of 90 countries. Prior studies have claimed that multilateral organizations were vital to global action against the HIV/AIDS epidemic. This study provides empirical evidence showing the actions taken by the multilateral organizations have both helped and hindered efforts to combat the HIV/AIDS epidemic.

The Political Significance of Social Media Activity and Social Networks

This paper examines panel data from two waves of the Youth Participatory Politics Survey, a nationally representative sample of young people in the United States. It employs a cross-lagged design to investigate the extent to which common forms of online activity create pathways to online and offline forms of political activity. Specifically, we examine the influence of Friendship-Driven (FD) and Interest-Driven (ID) online activity on online participatory politics and on offline forms of political action. Our findings reveal that FD and ID activity relate to political engagement, but in different ways. In addition, we find that the size of young people’s social networks interacts with both FD and ID online activity to promote political activity. This indicates that having exposure to “weak-ties” (resulting from large social networks) promote higher levels of political engagement. These findings demonstrate the need to specify the kinds of online activities in which youth are engaged and, more broadly, the political significance of social media and social networks     

Effect of Victimization on Impulse Control and Binge Drinking among Serious Juvenile Offenders from Adolescence to Young Adulthood

A vast literature has found longitudinal effects of early life stress on substance use and self-regulatory processes. These associations may vary by period-specific development among youth involved in the juvenile justice system. The current study used an accelerated longitudinal design and auto-regressive latent trajectory with structure residuals (ALT-SR) model to examine the within-person cross-lagged associations between binge drinking, impulse control, and victimization from 15 to 25 years of age. A large sample (N?=?1100) of justice-involved youth were followed longitudinally for 7 years (M _{age baseline} ?=?15.8, M _{age conclusion} ?=?22.8). In general, the sample was ethnically diverse (41% Black, 34% Hispanic, 21% White, 4.3% Other) and primarily male (87.2%). Participants reported on their frequency of binge drinking, impulse control, and frequency of victimization at each time point. The results indicated that, during adolescence, victimization and binge drinking attenuated impulse control, which resulted in more binge drinking and victimization during young adulthood. The current study highlights the importance of assessing developmental processes and period-specific transitions among at risk youth, especially for youth experiencing early life stress.     

Ideological congruence over government mandates under majoritarian and proportional representation electoral systems

The existing literature on ideological congruence has typically looked at congruence immediately after elections when governments are formed. This article goes beyond that comparative static approach by examining changes in citizen-government ideological congruence between two fixed points in time, namely at the beginning and end of government mandates. Building on a veto player approach and dynamics of party competition under majoritarian and proportional representation (PR) electoral systems, the results indicate, first, that government positions are more stable in between elections, as the number of parties and their ideological distance increase in cabinet. Second, it appears that single-party and homogeneous coalition governments decrease ideological congruence between elections under low levels of polarisation, while they increase congruence under very high levels of polarisation. Third, it was found that governments under majoritarian systems slightly decrease congruence between elections while congruence stays stable on average under PR systems. The different levels of party system polarisation across majoritarian and PR electoral systems mostly explain this difference.     

Economic Interests and Threat Assessment in the US Congress, 1890–1914

Why do some domestic actors see the international environment as a threatening place populated by untrustworthy powers, when others find opportunities for peaceful cooperation in the same conditions? Because these actors confront the same international environment, the reasons for their divergent evaluations must rest on differences in their own beliefs and interests. In this article, we consider the impact of societal interests in trade and trade protection on elite assessments of the international environment. We examine evaluations of the international environment in speeches given in the US Congress during naval appropriations debates between 1890 and 1914. The manufacturing sector’s interest in trade protection led political leaders who represented manufacturing regions to offer more negative assessments of the international environment, while those representing export-oriented agricultural areas of the country gave more positive evaluations. These effects were roughly comparable to those associated with party, as well as individual-level characteristics, such as having served as a military officer.     

The Contextual Causes of Issue and Party Voting in American Presidential Elections

This paper analyzes the influence of the two most commonly examined causes of presidential vote choice, policy preferences and party identification. The focus is on change across elections in order to assess how the effects of issues and partisanship respond to the larger political context in which voters make their decisions. In contrast to party centric views of politics, I find little direct responsiveness to party issue contrast and substantial influence of candidate issue contrast. Further, I find that leading hypotheses for the “resurgence in partisanship” are not consistent with some important facts suggesting that the explanation remains elusive.     

Reactions of potential jurors to a hypothetical malpractice suit: alleging failure to perform a prostate-specific antigen test

We conducted focus groups with 47 potential jurors who were presented with different scenarios in a hypothetical malpractice case involving failure to order a PSA test. Better documentation that a patient made an informed decision to decline a PSA test appeared to provide more medical-legal protection for physicians, especially with the use of a decision aid.     

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.
