The Limits of Ecological Inference: The Case of Split-Ticket Voting

We examine the limits of ecological inference methods by focusing on the case of split-ticket voting. Burden and Kimball (1998) report that, by using the King estimation procedure for inferring individual-level behavior from aggregate data, they are the first to produce accurate estimates of split-ticket voting rates in congressional districts. However, a closer examination of their data reveals that a satisfactory analysis of this problem is more complex than may initially appear. We show that the estimation technique is highly suspect in general and especially unhelpful with their particular data.     

British Imperialism in Fiji: A Model for the Semiotics of Cultural Identity

The history and effects of British imperialism in Fiji created a model for analyzing the semiotics of cultural identity. Following the acquisition of land in Fiji, the British recruited impoverished people from India and relocated them as indentured servants to do work on sugar cane plantations that natives refused to do. When Fiji became independent nearly 100?years later, the island nation had nearly equal populations of native Fijians and people of Indian decent. Fiji experienced three military coupes between 1987 and 2000 while the two ethnic and culturally distinct groups competed for jobs and political power. As a small, island nation, identity-based communication in Fiji represents a microcosm of other more complex multicultural societies. This study examines the semiotics of cultural identity among the people of Fiji.     

The study of legislative committees*

ABSTRACT

Proving that legislative committees really matter is not simple. The assembled papers aim to demonstrate fruitful paths to analysing when committees influence policy, what they can and should do, and how to detect their importance to the political process.     

Experimental Estimation of Heterogeneous Treatment Effects Related to Self‐Selection

Social scientists widely regard the random‐assignment experiment as the gold standard for making causal inferences about the world. We argue that it can be improved. For situations in which self‐selection and heterogeneity of treatment effects exist, an alternative experimental design that retains random assignment to treatment or control and supplements it with some self‐selection of condition offers a clear advantage. It reveals the average treatment effect while also allowing estimation of the distinct effects of the treatment on those apt and inapt to experience the treatment outside the experimental context.     

More on Measuring Two-Party Competition: A Response to Dunleavy

Gaines and Taagepera [(2013) How to operationalize two-partyness. Journal of Elections Public Opinion and Parties, 23(4), pp. 387–404] propose two indices of two-party competition for district-level data, both of which are alleged to be flawed. The case against them rests mainly on whether or not elections with one dominant party should be regarded as exhibiting one- or two-way competition. For those inclined to see 90–10% and 50–50% outcomes are different in kind, our indices can provide better measures than the popular effective number of parties or the “gap”. We agree that assessment of a set of outcomes, in a given election or over time, requires careful attention to the important distinction between micro-level data and aggregate measures.     

Institutional constraints,annexation and municipal efficiency in the 1960s

A sample of cities from 43 states is used to analyze how changes in institutions influence municipal expenditures and employment. Per capita costs and municipal employment are not found to be significantly influenced by a shift from restrictive to non-restrictive annexation laws. Municipalities operating under municipal-determination annexation laws are not found to experience significantly different growth rates in costs and employment per resident from that of cities operating under annexation laws which imposed a greater number of barriers to annexation.     

Reduced volume PCR amplification reactions using the AmpFlSTR Profiler Plus kit

The forensic community continues to seek improvements in DNA typing methods on aspects such as sensitivity and efficacy. Reducing the volume of the AmpFlSTR Profiler Plus reagents offered greater sensitivity and improved the chance of obtaining useful results for samples with very low quantities of DNA and multiple source samples. On the downside, amplifications initiated with less than 0.4 ng of DNA exhibited a twofold increase in the standard deviation of peak ratios. This research suggested a twofold approach to analyzing samples. For samples with greater than 0.25 ng of DNA, a 25 microL reaction is appropriate. Samples that did not demonstrate quantifiable results, or that have less than 0.25 ng, can be amplified by drying the sample directly in the PCR tube and amplifying in a 5 microL reaction. The analyst can expect at least limited results with as little as 0.03 ng of DNA in the 5 microL reaction.     

Job stress in police work: An exploratory analysis into structural causes

Police stress has received intermittent coverage in the literature for the last decade, and it remains a constant source of discussion today. One of the reoccurring problems with stress studies is that they attempt to examine the phenomenon globally. This almost always leads to generalized findings which may be representative of the overall problem, but certainly fail to adequately micro-examine the intracies of the issue. This article examines perceptions of stress relative to the demographic and assignment characteristics of police officers in a medium sized city. It identifies three specific patterns and suggests directions for additional research.
