The scheduling techniques of ESP2

The Mission Analysis Division of the Systems Analysis and Integration Laboratory at the Marshall Space Flight Center has developed a robust automatic scheduler which can produce detailed schedules for the multi-step activities required for payload operations on the Space Station. This scheduler, a part of the Expert Scheduling Program (ESP2), has five components: the bookkeeper, checker, loader, selector, and explainer. The bookkeeper maintains the usage profiles for nondepletable resources, consumables, equipment, crew, and the times of all the steps for the payload activities for several different schedules simultaneously. The checker searches the data maintained by the bookkeeper and finds times when the constraints of each step of an activity are satisfied. The loader is an expert system that uses the techniques of forward chaining, depth-first searching, and backtracking to manage the workings of the checker so that activities are placed in the schedule without violating constraints (such as crew, resources, and orbit opportunities). The checker searches the data maintained by the bookkeeper and finds times when the constraints of each step of an activity are satisfied. The loader is an expert system which uses the techniques of forward chaining, depth-first searching, and backtracking to manage the workings of the checker so that activities are placed in the schedule without violating the constraints. The selector has several methods of choosing the next activity for the loader to schedule. The explainer shows the user why an activity was or was not scheduled at a certain time; it offers a unique graphical explanation of how the expert system (the loader) works

Evaluation of a Program to Reduce Bullying in an Elementary School

Bullying is one of the most pervasive challenges in schools across the world. This investigation is an evaluation of a school’s attempt to address the large number of incidents of bullying. Materials from the Bully Free Classroom (BFC) by Allan Beane (2009) served as the intervention curriculum for 21, fifth grade students and six teachers. A 14-week (with the exception of school breaks), six lesson intervention was implemented with three groups of students: two groups identified as perpetrators and one group of victims. Teachers received training on bullying knowledge and how to appropriately report bullying-related incidents. Pre and post measures of bullying knowledge, frequency ratings of bullying and prosocial behaviors observed, and discipline referrals for bullying served as the dependent measures for the student participants. Results support the use of the intervention as the mean number of discipline referrals for participants of bully status significantly decreased, student ratings for negative behaviors significantly decreased, student knowledge of bullying significantly increased, and teacher’s ratings of the frequency of bullying decreased while school climate ratings became more positive. Moderate to large effect sizes are interpreted to provide strong support for a recommendation for school-wide adoption of the program. The scope and nature of the intervention plan is discussed in relation to recommended features of bully prevention and intervention programs and recommendations are made for implementation of this intervention

Local Labor Market Conditions and the Jobless Poor: How Much Does Local Job Growth Help in Rural Areas?

The employment outcomes of a group of jobless poor Oregonians are tracked in order to analyze the relative importance of local labor market conditions on their employment outcomes. Local job growth increases the probability that a jobless poor adult will get a job and shortens the length of time until she finds a job. After accounting for both the effects of personal demographic characteristics and local job growth, there is little evidence that the probability of employment or the duration of joblessness differs in rural compared with urban areas.employment, local labor markets, rural labor markets, rural poverty, unemployment, welfare reform, Labor and Human Capital,

EMPLOYMENT AND EARNINGS OF THE WORKING POOR IN RURAL AND URBAN LABOR MARKETS

We use a unique administrative database to analyze the impact of labor market conditions on the employment outcomes of working poor adults in Oregon. Stronger labor demand conditions are associated with better employment outcomes. Lower earnings and less steady employment in rural areas are largely explained by higher unemployment rates.Labor and Human Capital,

EMPLOYMENT GROWTH AND COMMUTING PATTERNS IN RURAL LABOR MARKETS

We estimate a county-level labor market model for Minnesota in order to decompose employment growth into labor force, commuting, and unemployment changes. Preliminary results suggest that 1990-2000 employment growth was accommodated by increased in-commuting and labor force growth, with in-commuting more important in metro than rural counties.Labor and Human Capital,

THE IMPACT OF THE 1990s ECONOMIC BOOM ON LESS-EDUCATED WORKERS IN RURAL AMERICA

This article uses National Longitudinal Survey of Youth (NLSY79) data to investigate the impact of local labor market conditions on the employment and earnings of rural non-college-educated workers. The results suggest that local economic conditions in the late 1990s did have a positive impact on wages, and the effect is larger for workers with no more than a high school degree compared to their college-educated counterparts. Further, there is evidence of a difference between rural and urban labor markets, suggesting that the 1990s boom helped urban less-educated workers but not those in rural areas. The rural/urban difference is most apparent for male workers.employment, local labor markets, NLSY79, rural, unemployment, wages, wage curve, Labor and Human Capital,
