Considering Mixed Mode Surveys for Questions in Political Behavior: Using the Internet and Mail to Get Quality Data at Reasonable Costs

Telephone surveys have been a principle means of learning about the attitudes and behaviors of citizens and voters. The single mode telephone survey, however, is increasingly threatened by rising costs, the declining use of landline telephones, and declining participation rates. One solution to these problems has been the introduction of mixed-mode surveys. However, such designs are relatively new and questions about their representativeness and the intricacies of the methodology remain. We report on the representativeness of a post election mixed-mode (Internet and mail) survey design of 2006 general election voters. We compare sample respondent means to sample frame means on key demographic characteristics and examine how mail and Internet respondents differed in terms of attitudes, behaviors and demographics. We find that overall the Internet respondents were representative of the population and that respondent choice of mode did not influence item response. We conclude that mixed-mode designs may allow researchers to ask important questions about political behavior from their desktops.     

Utilizing FDI to Stay Ahead: The Case of Singapore

A country of 5 million people in 710?km², Singapore has built itself into an integral part of global markets with living standards that are among the highest in the world. The purpose of this article is to apply a capabilities-based approach to understand how a small, resource-scarce country dependent on global markets has done so well. The core of Singapore??s success has been the continuous updating and expanding of domestic social capabilities to meet the needs of foreign companies. Government policies were hypersensitive to providing conditions for foreign firms to be successful. Foreign firms investing in Singapore by now have helped close the income gap with advanced economies and are on the way to closing the innovation gap. Singapore demonstrates that with deliberate attention to building skills, institutions and infrastructure, it is possible for a small country to upgrade skills and to move up the production-value chain with primary reliance on foreign direct investment (FDI). Cultivation of private Singaporean firms has been secondary but may be the next step needed to sustain progress, both to respond to increased competition from China and others, and to build a knowledge-based economy.     

Characterization and differentiation of aluminum powders used in improvised explosive devices – Part 1: Proof of concept of the utility of particle micromorphometry

Aluminum (Al) powders are commonly used in improvised explosive devices as metallic fuels, a component of explosive mixtures. These powders can be obtained readily from industrial‐scale and consumer products, and produced using unsophisticated “kitchen chemistry” techniques. This research demonstrates the potential of automated particle micromorphometry for comparisons between known source and questioned Al powders recovered from IEDs, as well as for insight into the method of Al powder manufacture. Al powder samples were obtained from legitimate manufacturers, and 56 samples were produced “in‐house” from Al‐containing spray paints and ball‐milled Al foils. Transmitted light microscope images of Al powder particles were acquired using an automated stage with automated z‐focus; 17 size and shape parameters were measured for all particles. Approximately 37,000–2,500,000 particles/sample were analyzed using an open‐source statistical package with customized code. Dimensionality reduction was required for processing the large datasets: eight of the 17 measured variables were selected based on inspection of the correlation matrix. Data from four subsamples from each of the 56 samples produced using “in‐house” methods were analyzed using ANOVA to assess the within‐ and between‐sample variation. High within‐sample variation was noted; however, ANOVA and post‐hoc Tukey's honestly significant difference (HSD) tests demonstrated that the between‐sample variation was substantially larger than the within‐sample variation. Each sample could be differentiated from all other samples in the test set. Future experiments will focus on ways to reduce the within‐sample variation, and additional statistical and microanalytical methods to classify sources and confidently constrain the method of Al powder manufacture.     

Cognitive-behavioral treatment of men who batter: The short-term effects of group therapy

A cognitive-behavioral approach for the treatment of wife abuse was evaluated using a pre-post design and multiple outcome measures. The treatment approach consisted of assertiveness training, relaxation training, and cognitive restructuring. Treatment also focused on increasing the client's acceptance of sex-role changes. Data were available on 92 men who completed 12 sessions of a skills group and eight sessions of a supplemental process group. There were significant changes in the desired direction in anger level, jealousy, depression, and attitudes about women's roles. These changes were maintained after adjusting scores for social desirability response bias. The importance of adjusting scores for response bias or obtaining spouse's reports of the man's behavior is discussed.     

A discriminant function analysis of deciduous teeth to determine sex

Studies of deciduous teeth have concluded that crown size differences in these teeth between males and females are not reliable sex discriminators, in contrast to such differences in permanent teeth. This study measured the mesiodistal and faciolingual crown diameters of all deciduous teeth, as well as those of the permanent first molars, of 162 children from the Burlington Orthodontic Growth Study, conducted earlier in Burlington, Ontario, Canada. All 40 deciduous tooth diameters (20 mesiolingual and 20 faciolingual) were significantly different between the sexes, as were the permanent tooth diameters. Using three to five measurements of deciduous teeth, discriminant analyses of several samplings of these children produced discriminant functions in which 76 to 90% of the holdout samples were correctly classified by sex. Combinations of deciduous and permanent measurements were used to classify 83 to 85% of the holdout samples correctly. When compared with published data on other sample populations, the Burlington group is the most dimorphic for deciduous teeth and is within the range of permanent tooth dimorphisms of other populations. The level of classification accuracy, when using discriminant analysis of the deciduous teeth, can approach the accuracy levels of analysis using the permanent teeth.     

Government Borrowing in Australia

This article examines the Australian experience with coordinatedgovernment borrowing from federation to the present day. Itreveals significant changes in the purposes for which the borrowingarrangements were originally designed and are now used. Largelyfor this reason, the outward form of the arrangements no longerresembles their actual operation, causing severe accountabilityproblems. Whatever the advantages of coordinated governmentborrowing for economic management in a federal system, the Australianexperience shows that it may have economic disadvantages aswell. The time has come, therefore, for the borrowing arrangementsto be rethought and revised.
