Reexamining the Relationship Between Fiscal Stress and Outsourcing

The determinants of outsourcing in local government are widely studied from a variety of frameworks. One concept consistently used to explain local government outsourcing is fiscal condition, with many noting that outsourcing is more likely when a local government’s fiscal condition declines into fiscal stress. Despite the ubiquity of this expectation in the outsourcing literature, several articles reviewed suggest that the findings for this relationship remain uncertain. As a result, the research presented in this article sought to examine and extend what is known about the relationship between fiscal stress and outsourcing in U.S. municipalities. The research includes previous measures of fiscal stress and adds new measures. In addition, it tries to overcome the limited theoretical testing of the relationship between fiscal stress and outsourcing by examining both direct and indirect effects of fiscal stress on outsourcing. It finds that municipalities in the United States that are experiencing fiscal stress are more likely to engage in outsourcing, particularly municipalities that are experiencing fiscal stress and have a positive evaluation of the external market to provide services.     

The Role of Theory in Experimental Design: Experiments Without Randomization

Some who have written about the logic of experimentation arguethat random assignment of subjects to treatment conditions isan essential attribute of an experiment. Others disagree. Ratherthan treating this as a matter of dueling definitions, we considerexperiments without randomization from a theoretical perspective.Our central contention here is that, for some research questions,theory dictates systematic (not random) assignment of respondentsto experimental conditions. Two such areas of inquiry are researchon political tolerance and on institutional legitimacy. Thisarticle gives cursory attention to the former body of work anddetailed attention to the latter, based on an experiment conductedin a survey in 2001 on the consequences of the American presidentialelection for institutional legitimacy. Because in both instancestheory requires nonrandom assignment, the problem becomes oneof identifying the costs of nonrandomization (threats to internalvalidity) and specifying analytical techniques that might amelioratethose costs. Consequently, we present results from a statisticalapproach that addresses the problem of nonrandomization. Themost important claim of this article is that theory ought tospecify research design, including experimental designs, andthat dogmatic attachment to one definition of experiment willnot serve the discipline of political science.     

Stressful life events and adolescent drug use: Moderating influences of the MAOA gene

Purpose

Though stressful life events appear to impact the likelihood and frequency of substance use among adolescents, these effects are often varied and inconsistent. We suggest that the polymorphic MAOA gene may be partially responsible for variable susceptibility to environmental pressures and substance use. More specifically, we hypothesize that adolescents possessing low activity alleles for the MAOA genotype are more likely to respond to stressful life experiences by initiating substance use.

Methods

The genetic subsample of the National Longitudinal Study of Adolescent Health was analyzed (2,574 adolescents) using logistic regression models for each gender. Respondents’ self-reports of eight key stressors were used to create a composite life stress scale which was allowed to interact with a variable that represented the number of low activity MAOA alleles.

Results

For males, a significant interaction emerged between stressful life experiences and the MAOA gene for alcohol (p = .029) and marijuana (p = .039) initiation. For females, the interaction was not significant in each model.

Conclusions

MAOA interacts with life stress to increase the likelihood of substance use initiation for males. Those with a low activity MAOA allele are more likely to initiate substance use than those with a high activity allele when exposed to stressful experiences.
