The Role of Leaders in Intra-Alliance Bargaining

This article develops a theory about the role of leaders in long-term international bargaining, specifically in the context of negotiations within existing military alliances. The international relations literature suggests that domestic opposition (to cooperation on a particular issue) increases a state’s bargaining power vis-á-vis its negotiating partner. This study confirms that domestic opposition to cooperation generally increases a state’s bargaining power at the international level, but it suggests that domestic opposition to the state’s leader – which affects the leader’s vulnerability – does not have a uniform effect on the country’s bargaining power. It demonstrates the central role a state leader plays in international bargaining and explains the dynamics of alliance negotiations left unexplained in the literature. In order to examine the argument, this study uses “structured, focused comparison” of the U.S. alliances with Japan and Spain.

When Should We Use Unit Fixed Effects Regression Models for Causal Inference with Longitudinal Data?

Many researchers use unit fixed effects regression models as their default methods for causal inference with longitudinal data. We show that the ability of these models to adjust for unobserved time‐invariant confounders comes at the expense of dynamic causal relationships, which are permitted under an alternative selection‐on‐observables approach. Using the nonparametric directed acyclic graph, we highlight two key causal identification assumptions of unit fixed effects models: Past treatments do not directly influence current outcome, and past outcomes do not affect current treatment. Furthermore, we introduce a new nonparametric matching framework that elucidates how various unit fixed effects models implicitly compare treated and control observations to draw causal inference. By establishing the equivalence between matching and weighted unit fixed effects estimators, this framework enables a diverse set of identification strategies to adjust for unobservables in the absence of dynamic causal relationships between treatment and outcome variables. We illustrate the proposed methodology through its application to the estimation of GATT membership effects on dyadic trade volume.     

Uneven institutional configurations and sectoral variation in China's socialist market economy: a comparative study of three pillar industries

By comparing three Chinese pillar industries, automobile, petroleum, and machinery, this paper analyzes how the development of uneven institutional configurations bred sectoral variation in transitional China. In 1994, at the dawn of the Chinese socialist market economy, the State Council issued guidelines for national industrial policy and proposed the enactment of similar growth-promoting policies for all pillar industries. The level of policy enactment and the resulting outcomes, however, vary significantly across the industries. Previous literature on China's rapid industrialization has sought to build a single model encompassing China as a whole, and has emphasized either the state's institutional capacity or China's unique governance mechanisms. This study investigates China's industrialization by taking account of the uneven development of institutional capacity amid macro institutional reforms. Every idea and institution evolved at a different pace in these reforms, and the incremental nature of the reforms further deepened the gaps between sectors. This paper argues that, due to this uneven development, the Chinese state was not strong enough to be considered a developmental state until at least the early 2000s.     

How Does Race Affect Perceptions of Police Trustworthiness?

While race is often discussed in relation to police, there is still little empirical evidence on the role of race in shaping citizens’ evaluations of government performance. Using an experimental design, this study examines how different levels of police performance affect perceptions of police trustworthiness and to which degree observed effects vary by individual race and across communities with different racial makeups. Specifically, we study the effect of different levels of performance on perceived trustworthiness in two communities—one predominantly African American and one predominantly White—and replicate across two samples: a sample consisting of primarily White participants and another consisting of only African American participants. Results indicate that the interaction between the racial composition of a community and individual race plays a critical role in shaping the effects of performance among White participants, who appeared more sensitive to community context than African American participants. Implications for research and practice are discussed.     

Assessing the effectiveness of mental health courts: A quantitative review

Purpose

The purpose of this review is to quantitatively review the accumulating MHC studies that have been conducted of both peer-reviewed and non-peer-reviewed studies. The primary objective of the current study is to provide a clearer picture as to whether MHCs are an empirically efficacious intervention for a significant health and criminological problem.

Methods

This study used meta-analytic techniques to assess the effectiveness of MHCs. A systematic search of the literature and electronic databases through July 2009, as well as an e-mail survey of mental health court program directors, generated 18 studies.

Results

Aggregate effects for recidivism outcomes revealed a mean effect size of -0.54 and -0.55 among quasi-experimental studies analyzed separately. There was a positive improvement among a limited number of clinical outcomes.

Conclusions

Our findings suggest that MHCs are an effective intervention but this assertion is not definitive. Methodologically, many of the studies are not as strong as would be ideal thus limiting our conclusions.     

Tissue distribution of tetramethylthiuram disulfide in warm-blooded animals

The objective of the present work was to study the distribution of tetramethylthiuram disulfide (TMTD) in the body of warm-blooded animals as exemplified by white rats. TMTD was administered intragastrically and detected in the unaltered form in other internal organs. It was found to accumulate in the largest amounts in the gastric contents, kidneys, and urine.     

Rapid direct PCR for ABO blood typing

Many different molecular typing methods have been reported to complement routine serological ABO blood typing in forensics. However, these ABO genotyping methods are often time-consuming and call for an initial DNA isolation step that requires the use of expensive kits or reagents. We report here a rapid direct ABO genotyping method that eliminates the need for DNA extraction from fresh blood, hair, and body fluid stains before PCR. Using a fast PCR instrument and an optimized polymerase, the genotyping method-which employs a multiplex allele-specific primer set for the simultaneous detection of three single-nucleotide polymorphism (SNP) sites (nucleotides 261, 526, and 803)-identifies A, B, O01/O02, O03, and cis-AB01 alleles in around 70 min from sample collection to electropherogram. Not only will this ABO genotyping method be efficiently used in forensic practice for rapid screening of samples before full-blown multilocus short tandem repeat profiling, but it will also demonstrate an example of rapid direct genotyping of SNPs that offers the advantages of time- and cost-efficiency, convenience, and reduced contamination during DNA analysis.     

A fast preparation of skeletal materials using enzyme maceration

The current study investigates the removal of soft tissues from mice and rats by the use of three different proteases and one lipase from Novozymes A/S. The results demonstrate the enzyme maceration to be remarkably fast (1-3 h) compared to the traditional warm-water procedure, which requires up to several days. In addition, the enzyme maceration eliminates the odor problem associated with the traditional procedure. It is shown that stirring of the enzyme maceration bath is the main factor which determines the speed of the maceration. For mice, the time required for enzyme maceration can vary from 1 to 8 h depending on the stirring speed. The method investigated here allows preparation of skeletal material in an essentially odorless way within a matter of hours, making the method useful in particular for forensic science, private conservation workshops, and educational purposes.
