In the early 2000s, the Montgomery County (Maryland) Public School system implemented district-wide changes to funding, curriculum, staffing, and technology. Using data from 1995 to 2014, we employ a difference-in-differences strategy to show that the reforms significantly increased the percentage of students in Montgomery County who scored advanced on third- and fifth-grade math and reading tests. Using an event study strategy, we find that the positive impacts extended through the end of the panel. Our results contribute to the literature on school reform by finding positive impacts of school reform in a district that was high performing prior to reforms.  相似文献

Estimates suggest that 10 000 farms in the UK offer bed and breakfast (B and B) serviced accommodation. A thorough review of the existing literature indicates over 50% of Devon and Cornwall's farmhouse B and B sector operate without participating in any form of quality assurance inspection scheme. This research executes a stratified postal survey to gain a comprehensive understanding of Devon's farmhouse B and B product, with particular interest in extracting providers' attitudes towards quality assurance inspection schemes. The very representative results suggest a divergence of attitudes towards the notion of quality inspections for all farmhouse B and B providers. Copyright © 2002 John Wiley & Sons, Ltd.  相似文献

This paper describes a field experiment with a self-leadership training aimed at helping human service professionals to improve their detached concern and proactivity. Whereas detached concern refers to a state in which human service professionals blend compassion with emotional distance in their interaction with clients, proactivity refers to self-starting and change-oriented behaviour to enhance personal or organizational effectiveness. Based on self-leadership theory, we hypothesized that self-leadership training can enhance detached concern and proactivity. Moreover, based on behavioural plasticity theory, we hypothesized that training participants who are low in occupational self-efficacy are more susceptible to the external influence of self-leadership training, than individuals with higher levels of occupational self-efficacy. We conducted a field experiment with a sample of 223 human service professionals who were either assigned to a training group (n = 94), or a wait-list control group (n = 129). In a 3-month follow-up study, we found that self-leadership training had a positive effect on detached concern and that the intervention was especially effective for participants with low to medium initial levels of pretraining occupational self-efficacy. However, the intervention did not affect participants' level of proactivity. This study adds to the literature on workplace learning by demonstrating the potential of a self-leadership training for the transfer maintenance of newly developed soft skills (i.e., detached concern and proactive behaviour) to the workplace and by pinpointing occupational self-efficacy as an individual predisposition that influences training success.  相似文献
