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.     

Effects of Group Practice of the Transcendental Meditation Program on Preventing Violent Crime in Washington,D.C.: Results of the National Demonstration Project,June--July 1993

This paper reports the results of a prospective experiment in which a group of approximately 4,000 participants in the Transcendental Meditation and TM-Sidhi programs of Maharishi Mahesh Yogi assembled in Washington, D.C., from June 7 to July 30, 1993. It was hypothesized that levels of violent crime in the District of Columbia would fall substantially during the Demonstration Project, as a result of the group's effect of increasing coherence and reducing stress in the collective consciousness of the District. A 27-member Project Review Board comprising independent scientists and leading citizens approved the research protocol and monitored the research process. Weekly crime data was derived from database records provided by the District of Columbia Metropolitan Police Department (DCMPD), which are used in the FBI Uniform Crime Reports. Statistical analysis considered the effect of weather variables, daylight, historical crime trends and annual patterns in the District of Columbia, as well as trends in neighboring cities. Consistent with previous research, levels of homicides, rapes and assaults (HRA crimes) correlated with average weekly temperature. Robberies approximately followed an annually recurring cycle. Time series analysis of 1993 data, controlling for temperature, showed that HRA crimes dropped significantly during the Demonstration Project, corresponding with increases in the size of the group; the maximum decrease was 23.3% (p < 2 × 10–9) [24.6% using a longer baseline, with 1988--1993 data (p < 3 × 10–5)], coincident with the peak number of participants in the group during the final week of the assembly. When the same period in each of the five previous years was examined, no significant decreases in HRA crimes were found. Robberies did not decrease significantly. However, a model that jointly estimated the effect of the Demonstration Project on both HRA crimes and robberies showed a significant reduction in violent crimes overall of 15.6% (p = 0.0008). Further analysis showed that the effect of the coherence-creating group on reducing HRA crimes could not be accounted for by additional police staffing. The time series analysis for HRA crimes gave results that are highly robust to alternative model specifications, and showed that the effect of the group size was cumulative and persisted after the Demonstration Project ended. Also, calculation of the steady state gain based on the time series model predicted that a permanent group of 4,000 coherence-creating experts in the District would have a long-term effect of reducing HRA crimes by 48%.

Estimating chance reproducibility in Guttman Scaling

A definition of reproducibility in Guttman Scaling and two chance measures of reproducibility are suggested. The first measure assumes that the items are independent. The second method assumes nonindependent items and fits respondent and item margins by an iterative method used in fitting log-linear models. Chance reproducibility is conceptualized in terms of assumptions about respondent variability.     

ON THE DESIGN OF HIERARCHICAL PRODUCTION PLANNING SYSTEMS

To provide effective managerial support for decisions related to production planning and scheduling processes, it is useful to partition the set of decisions into a hierarchical framework. In the resulting system, higher level decisions impose constraints on lower level actions, and lower level decisions provide the necessary feed-back to reevaluate higher level actions. The purpose of this paper is to suggest optimum procedures to deal with the resulting subproblems and to analyze the interaction mechanisms among the different hierarchical levels. Computational results are given.     

A COMPUTER SIMULATION APPROACH TO THE TEACHING OF MAIL SURVEY STRATEGY ALTERNATIVES AND CHOICE

The author uses a computer simulation of mail questionnaire response rates to acquaint students with trade-offs in terms of survey cost, accuracy, and time. In the absence of a theoretical base in the literature, the approach familiarizes students with current issues and problems, and helps to develop a decision-making framework for this survey method. A step-by-step procedure emphasizing student involvement is described.
