Active control system trends

The active control concepts which achieve the benefit of improved mission performance and lower cost and generate system trends towards improved dynamic performance, more integration, and digital fly by wire mechanization are described. Analytical issues and implementation requirements and tools and approaches developed to address the analytical and implementation issues are briefly discussed

The Changing Labor Market Position of Canadian Immigrants

This paper uses pooled 1971, 1981, and 1986 Canadian census data to evaluate the extent to which (1) the earnings of Canadian immigrants at the time of immigration fall short of the earnings of comparable Canadian-born individuals, and (2) immigrants' earnings grow more rapidly over time than those of the Canadian-born. Variations in the labor market assimilation of immigrants according to their gender and country of origin are also analyzed. The results suggest that recent immigrant cohorts have had more difficulty being assimilated into the Canadian labor market than earlier ones, an apparent consequence of recent changes in Canadian immigration policy, labor market discrimination against visible minorities, and the prolonged recession of the early 1980s.

Deconstructing therapy outcome measurement with Rasch analysis of a measure of general clinical distress: the Symptom Checklist-90-Revised

Rasch analysis was used to illustrate the usefulness of item-level analyses for evaluating a common therapy outcome measure of general clinical distress, the Symptom Checklist-90-Revised (SCL-90-R; Derogatis, 1994). Using complementary therapy research samples, the instrument's 5-point rating scale was found to exceed clients' ability to make reliable discriminations and could be improved by collapsing it into a 3-point version (combining scale points 1 with 2 and 3 with 4). This revision, in addition to removing 3 misfitting items, increased person separation from 4.90 to 5.07 and item separation from 7.76 to 8.52 (resulting in alphas of .96 and .99, respectively). Some SCL-90-R subscales had low internal consistency reliabilities; SCL-90-R items can be used to define one factor of general clinical distress that is generally stable across both samples, with two small residual factors

Determining the Future for Louisiana Sugar Cane Products, Inc.: A Case Study Analyzing Vertical Coordination Options

Deciding how to coordinate activities can be a challenge posed in any marketing chain. This case involves an agricultural cooperative that has focused entirely on marketing raw sugar cane for additional refinement. Recent dramatic shifts in the sector have caused the members of the cooperative to consider building a facility that will process the raw sugar cane. In so doing, the cooperative can consider using the spot market, using contracts, vertically coordinating, or vertically integrating. This case study of Louisiana Sugar Cane Products, Inc. is a unique, real-life case that can be widely used in marketing and cooperatives courses.Agribusiness, Crop Production/Industries,

Construction Superintendent Skill Sets

This is the first of a series of articles reviewing the results of an ongoing qualitative research project designed to document construction superintendent skill sets and develop postsecondary curricula to support superintendent education. Varying views of the role of the superintendent and an historical perspective are presented in a review of literature. The research methodology for the entire project, as well as this first phase, is presented. Data have been coded and analyzed from the interviews with seven superintendents to date and the results of these analyses are provided. Themes that emerged in these interviews include people skills, understanding the work and sequencing, organizational and managerial skills, scheduling, estimating, cost control/awareness, work ethic, and learning from other people. Insights into how the role of the superintendent has changed and the preparation needed for future superintendents also are provided from these interviews. These preliminary results indicate there is a role for colleges and universities in developing these skill sets, and that construction superintendents now are doing tasks formerly thought to be the responsibility of project managers. The Technology Age coupled with our litigious society is forcing the construction superintendent into a new role
