Quality of Post-1965 Asian Immigrants

The reliance on an overall average approach to the labor market quality of immigrants could generate misleading information and biased policy recommendations. Focusing on Asian immigrants, this article demonstrates that much insight into immigrant quality can be gained via a diversity approach. Using the 5% PUMS data of the 1990 U.S. census, this paper shows that a common perception that the quality of post-1965 immigrants is lower than natives and earlier immigrants is invalid for post-1965 Asian immigrants. Unlike their Latin American counterparts, post-1965 Asian immigrants are generally more educated and skilled than natives. The educational level of post-1965 Asian immigrants surpasses that of their pre-1965 counterparts, despite their disadvantage in occupational attainment due to their shorter time of adaptation. Diversity also characterizes educational and occupational attainment across major post-1965 Asian immigrant groups and within each Asian immigrant group before and after 1965. Gender does not alter the advantage of post-1965 Asian immigrants over natives and their pre-1965 parallels in education, but it does complicate their occupational status. Policy implications of the findings are considered.     

MANAGING ACADEMIC INTERDISCIPLINARY RESEARCH PROJECTS*

This field study provides variables that can be used by practitioners as action levers and by future researchers as the basis for theoretical development. Conclusions from relevant literature and findings from interviews with interdisciplinary research management identified forty variables that were viewed as important to interdisciplinary research project success. After adjusting the data for reliability attenuation, these variables were further analyzed to identify the best prediction equation. The findings suggested that project age or the longevity of the project and open discussion of disagreements were the best predictors of performance.     

An Experimental Test of the Effects of Fictional Framing on Attitudes*

Objectives. Most studies of media effects in political communication focus on news media. A smaller body of work extends theories of news media effects to fictional entertainment media. Just as news media engage in priming and agenda setting, these studies suggest that fictional media do as well. In this study, we deal with fictional media's framing of issues. No research has sought to test the effects of framing in explicitly fictional media on political opinions. We develop the outlines of a theory we call “fictional framing” and test it in an experiment. Methods. Participants in our treatment group watched the film Cider House Rules. The movie frames the issue of abortion in the case of incest in a pro‐choice way, and frames morality in terms of following one's own conscience. Results. The film influenced opinions in ways consistent with the framing of these issues. Conclusions. Since abortion opinions and moral values tend to be entrenched, we consider this a strong first test of the effects of fictional framing.     

Religious affiliation and Hispanic health in Utah

Two research hypotheses are addressed in this study. (1) Do health trajectories of Hispanics in Utah differ from what has been documented in states with longstanding large Hispanic populations? (2) Do non-Mormon groups in Utah have less favorable health status than Mormons in Utah? This study employs three health outcome measures: activity limitations caused by emotional problems, activity limitations caused by physical problems, and self-rated health status using the 2001 Utah Health Status Survey. Comparisons of Hispanics in their traditional settings within the U.S. generally show more favorable health status for Hispanics than for whites. We find little difference in health status between Hispanics in Utah and their Anglo counterparts. Hispanics were more likely than Anglos to have “a little” activity limitation due to physical problems, but were not more likely to report “a little” or “considerable” activity limitations due to emotional or physical problems. Hispanics and Anglos were statistically equal in probability of self-reported fair to poor health. Important in relation to studies outside of Utah, we find little support for the epidemiologic paradox, the usual finding of more favorable health for Hispanics than for whites. As with ethnicity, we find little difference between non-Mormon and Mormons with respect to health. The most notable exception is that Mormon Hispanics are at a significantly greater risk of emotional problems than Catholic Hispanics in Utah.     

On trends and constants in periodic autoregressions

Periodic autoregressions are characterised by autoregressive structures that vary with the season. If a time series is periodically integrated, one needs a seasonally varying differencing filter to remove the stochastic trend. When the periodic regression model contains constants and trends with unrestricted parameters, the data can show diverging seasonal deterministic trends. In this paper we derive explicit expressions for parameter restrictions that result in common deterministic trends under periodic trend stationarity and periodic integration.     

Assessing robustness of crossover designsto subjects dropping out

In some crossover experiments, particularly in medical applications, subjects may fail to complete their sequences of treatments for reasons unconnected with the treatments received. A method is described of assessing the robustness of a planned crossover design, with more than two periods, to subjects leaving the study prematurely. The method involves computing measures of efficiency for every possible design that can result, and is therefore very computationally intensive. Summaries of these measures are used to choose between competing designs. The computational problem is reduced to a manageable size by a software implementation of Polya theory. The method is applied to comparing designs for crossover studies involving four treatments and four periods. Designs are identified that are more robust to subjects dropping out in the final period than those currently favoured in medical and clinical trials.     

A vector of quarters representation for bivariate time series

In this paper it is shown that several models for a bivariate nonstationary quarterly time series are nested in a vector autoregression with cointegration restrictions for the eight annual series of quarterly observations. Or, the Granger Representation Theorem is extended to incorporate, e.g., seasonal and periodic cointegration.     

Trimmed and Outer Means and Their Variances

Some properties of trimmed and outer means for the normal situation are considered; in particular, the mean of the outer half of the sample has the same variance as the mean of the inner half. An inequality involving variances of unbiased estimators of location and their complements is derived and some of its consequences are examined.
