Although GSS researchers recognize the importance of communication within the group in determining the final group output, little attention has been given to the information that the individual group members possess prior to the group activity as a basis for this communication. -I'he purpose of this study was twofold: (1) to characterize the pre-group, task-related information that individuals ...

The authors reported the results of field survey and family follow-up on acatalasemia and hypocatalasemia during the year of 1965. No hypocatalasemic case was seen in the tests of 2,897 individuals at two places of Japan Proper. And a hypocatalasemic boy was found out among 10,083 children of Miyako Is., Ryukyu. In 1965, ten acatalasemias of six families at various parts in the world were added...

Extreme and non-extreme response styles (RSs) are prevalent in survey research using Likert-type scales. Their effects on measurement invariance (MI) in the context of confirmatory factor analysis are systematically investigated here via a Monte Carlo simulation study. Using the parameter estimates obtained from analyzing a 2007 Trends in International Mathematics and Science Study data set, a ...

Evidence provided by Weir and Smith, particularly the findings from the National Health and Nutrition Examination Survey (NHANES), leads us to conclude that an increase in arthritis prevalence during the 1990s in the United States is probable, but the trend is likely overstated in the Health and Retirement Study (HRS). We show that a mistake in our earlier method does not change substantively o...

An important parameter that defines the effectiveness and efficiency of any optical or infrared sky survey is the atmospheric characteristics of the observing site. Of prime importance is the sky spectral brightness, which determines the sensitivities and the observing time required to complete a particular survey. This paper presents observations of the near-infrared sky spectral brightness me...

IC ER SPTIVES On contentious issues such as gun control, where advocacy groups on both sides claim to have the weight of public opinion behind them, polling can help clarify what Americans really think. Three decades of polling have painted a clear picture of public opinion about gun control. These polls show that public support for the regulation of firearms is strong, deep, and widespread. La...

This paper studies completed parity distributions for all the industrialized and developing countries that participated in the World Fertility Survey. This is done by means of a table based on parity calculated for all ever-married women above age 40 by educational and residential subcategories. The information is also used to compare mean family and mean sibship sizes and to study changes in...

Usability testing, commonly conducted for commercial software to ensure that it meets the needs of the end user, is likewise vital to creating effective training software employing VR technologies. However, developers often limit software testing to expert evaluation (by other developers or subject matter experts [SMEs]) to identify potential problems that might impede the usability or acceptab...
