The impact of regional difference in unionism on employment

A study of whether changes in unionism affect the aggregate level of employment in the economy and, in particular, whether an individual who lives in an SMSA where unions are weak is more likely to be employed than an individual who lives in an area where unions are strong.Labor unions ; Employment (Economic theory) ; Labor supply ; Regional economics

Cyclical versus Secular Movements in Employment Creation and Destruction

This paper offers an analysis of cyclical and secular patterns in job turnover using establishment-level data. We provide evidence from multiple data sets that show that the job turnover process is markedly different over time and across regions. Over time, we find that employment fluctuations are associated primarily with job destruction. Across regions, employment differences are associated more with job creation. Differences were found between the cyclical (within) and secular (across state) responses in job creation and destruction to output shocks. Movements in job creation and destruction were also found to be related to the types of human capital externalities or technological spillovers used to explain long-run differences in regional or national growth rates.

Employment creation and destruction: an analytical review

A presentation of some new evidence on differences in the causes of high- and low-frequency movements in employment, focusing on whether the components of cyclical and secular (regional) variations in job growth follow similar patterns.Employment (Economic theory) ; Regional economics

The Impact of 4 X 4 Block Scheduling at an Urban High School

The primary purpose of this study was to examine whether attendance, academic achievement, school climate, student stress, and teacher burnout improved in an inner city, predominantly African American high school after the implementation of a 4 x 4 block schedule. Data concerning student academic achievement and absenteeism in 14 classrooms were gathered from the school\u27s Annual Scholastic Reports. Data concerning the instructional practices of eight teachers were gathered through the teacher version of the Instructional Practices Survey and compared to a student version of the Instructional Practices Survey to determine whether student perception of instructional practices coincided with the teachers\u27 perceptions. Classroom climate was examined by administering the Classroom Environment Survey to seven teachers and 130 of their students. Student stress levels were examined from the results of the School Situation Survey returned by 106 students. The Maslach Burnout Inventory was used to gather data concerning the burnout levels of 13 teachers. This study found that increases in grade point average and decreases in absenteeism were not achieved after three years of block scheduling. Instructional practices of the teachers involved in this study did not change significantly. School climate, student stress levels, and teacher burnout were found to be in the average range

SELECTING FUNCTIONAL FORM IN PRODUCTION FUNCTION ANALYSIS

Functional form selection is a sometimes neglected aspect of applied research in production analysis. To provide an improved and uniform basis for form selection, a number of traditional and popular functional forms are catalogued with respect to intrinsic properties. Guidelines for the conduct of form selection are also discussed.Production Economics, Research Methods/ Statistical Methods,

Initial assessments of life support technology evolution and advanced sensor requirements, volume 2, appendix A

The primary issues studied were how the transition from a physical/chemical (P/C) to hybrid to a Closed Ecological Life Support System (CELSS) could be achieved, what sensors and monitors are needed for a P/C -CELSS hybrid system, and how a CELSS could be automated and what controls would be needed to do so

Pattern in Regional Labor Market Adjustment: The United States vs. Japan

In this paper I examine regional labor market behavior in the United States and Japan. In contrast with the picture at the aggregate level, Japanese labor markets at the prefectural (regional) level appear to exhibit substantially more persistence than state level labor markets in the United States. The distribution (and positions of regions within the distribution) of wages, unemployment, employment growth, and migration remain remarkably constant in Japan for periods of up to 15 years. Although wages, unemployment, and migration appear to be driven by similar factors in both countries, wages appear to be slightly more sensitive while unemployment is less sensitive to demand shifts in Japan than in the U.S.

Dynamically-compacted cement stabilised soil blocks for low-cost walling

This document contains the detailed results and conclusions of work carried out during a PhD to investigate the processing, production and performance of dynamically compacted cement-stabilised soil blocks suitable for sustainable low-cost building. An earlier project carried out by the author demonstrated that full-size blocks could be manufactured by dynamic compaction. It was hoped that this technique could be applied to the self-evident need for low-cost housing in the humid tropics. The apparent advantages of this process, over quasi-static compression (slow steady squeezing), have led to further investigation into the critical factors influencing the production of such building units. Initial tests on small cylindrical samples produced by both quasi-static compression and dynamic compaction provided a means of comparison and helped to develop relationships between dominant variables. These tests showed that the moisture content of the compact was a critical variable, influencing its consolidation and its final cured strength. Optimisation studies were undertaken to determine acceptable parameters for impactor mass, drop height and number of applied blows. These chosen parameters were then extrapolated to full-size block production with the necessary adjustments for practicality and cost. Full-size block production using the Test Rig indicated similar relationships as those discovered at the smaller scale, including the more effective consolidation offered by dynamic compaction. From this experience a production prototype was designed and disseminated to a collaborator in India for further trials and feasibility studies. These trials demonstrated that dynamic compaction could produce blocks with a 7-day wet compressive strength of between 3-5MPa with only 5% cement, (typical building regulations require block strength greater than 3.5MPa after 28-days). Feasibility studies there indicate dynamic compaction offers potential savings of 40% compared with local high-tech CSSB manufacture
