This study analyzes the influence of local labor market conditions on the year-to-year persistence and attainment decisions
of a sample of traditional-aged students who attended community colleges during the 1990s. The findings suggest that the enrollment
and attainment decisions of these first-time community college students were not made purely as a response to changes in tuition
costs, but rather the result of a more interconnected process whereby changes in tuition, local labor market conditions, and
the relative change in both are considered. For those who are sensitive to these relative costs, the likelihood of dropping
out is increased. Of those who remained enrolled, the evidence suggests that an increase in tuition appears to provide an
incentive or extra motivation to finish a degree, especially an associate’s degree. This finding does not support the raising
of in-state tuition to improve student outcomes; rather it draws attention to the complexity involved in student persistence
and attainment decision-making. 相似文献

We study the production of knowledge when many researchers or inventors are involved, in a setting where tensions can arise between individual public and private contributions. We first show that, without some kind of coordination, production of the public knowledge good (science or research software or database) is sub-optimal. Then we demonstrate that if ‘lead’ researchers are able to establish a norm of contribution to the public good, a better outcome can be achieved, and we show that the general public license (GPL) used in the provision of open source software is one such mechanism. Our results are then applied to the specific setting where the knowledge being produced is software or a database that will be used by academic researchers and possibly by private firms, using as an example a product familiar to economists, econometric software. We conclude by discussing some of the ways in which pricing can ameliorate the problem of providing these products to academic researchers. 相似文献

By using the PatVal-EU dataset we find that the most important determinant of patent licensing is firm size. Patent breadth, value, protection, and other factors suggested by the literature also have an impact, but not as important. In addition, most of these factors affect the willingness to license, but not whether a license actually takes place. We discuss why this suggests that there are transaction costs in the markets for technology. The issue is important because many potential licenses are not licensed suggesting that the markets for technology can be larger, with implied economic benefits. 相似文献

The interpretation of cognitive test scores often leads to decisions concerning the diagnosis, educational placement, and types of interventions used for children. Therefore, it is important that practitioners administer and score cognitive tests without error. This study assesses the frequency and types of examiner errors that occur during the administration and scoring of the Woodcock‐Johnson III Tests of Cognitive Abilities (WJ III COG). Data from 36 graduate students across 108 test records revealed a total of 500 errors across all records. Further analyses indicated three frequently occurring errors, including the use of incorrect ceilings, failure to record errors, and failure to encircle the correct row for the total number correct. The results of this study may be used to inform training programs so that appropriate steps can be taken to decrease the number of examiner errors on the WJ III COG and similar cognitive test batteries. © 2009 Wiley Periodicals, Inc. 相似文献

This study examines the influence of forgiveness and gratitude on life satisfaction and subjective well-being among Filipino adolescents. Two hundred and ten (210) Filipino college students were recruited as respondents for the empirical inquiry. Results indicated that gratitude served as the most robust determinant of well-being after controlling demographic characteristics and forgiveness dimensions. Most importantly, gratitude and forgiveness of self, which is a dimension of forgiveness, predicted subjective well-being beyond the influence of the Big Five personality factors. These findings strengthened the empirical evidence that moral traits would have unique contributions on subjective well-being, even after controlling the impact of Big Five personality factors. Implications of the results are discussed in the context of counseling. 相似文献

The present study examined the psychometric relationship between two new rating scales, the Behavior Assessment System for Children (BASC; Reynolds & Kamphaus, 1992) and the Social Skills Rating System (SSRS; Gresham & Elliott, 1990), for a sample (N = 53) of minority kindergarten children using both parent and teacher ratings. The similarities and differences between these instruments were investigated through correlational and content analyses. In general, the results provide preliminary convergent validity evidence for the BASC and SSRS. In regard to the Social Skills subscale of the BASC, convergent validity evidence was demonstrated for the parent form of this instrument, but not the teacher form, when the SSRS Social Skills scale was used as the criterion. In addition, the correlations between the various scales of the BASC and SSRS were in the expected direction. That is, the correlation between the BASC Adaptive Skills Composite and the SSRS Social Skills scale was moderate in the teacher group (r = .44) and high in the parent group (r = .54). Similarly, correlations between the BASC Hyperactivity, Aggression, and Externalizing scales and the SSRS Problem Behaviors scale ranged from .50 to .60 and .50 to .56 in the teacher and parent groups, respectively. Implications regarding the practical utility of the BASC and SSRS for assessing social skills functioning, in particular, were presented. © 1996 John Wiley & Sons, Inc. 相似文献

Objectives: To investigate the effects that high-velocity, low-load (HVLL) and low-velocity, high-load (LVHL) resistance exercise, performed once or twice-weekly, have on indices of functional performance (primary outcome), maximal strength, and body composition (secondary outcomes) in older adults.Methods: In a randomised, controlled, multi-armed, parallel design, 54 moderately-highly active, but resistance exercise naïve older adults (aged 60–79 years), attended baseline and post-10-week intervention assessment sessions. Physical and functional assessments were completed, and predicted one-repetition maximums (1-RM) were obtained for eight exercises. Participants were then randomised into one of five conditions: HVLL once-weekly (HVLL1: n?=?11) or twice-weekly (HVLL2: n?=?11), LVHL once-weekly (LVHL1: n?=?10) or twice-weekly (LVHL2: n?=?11), no-exercise control condition (CON: n?=?11). The HVLL conditions completed 3 sets of 14 repetitions at 40% 1-RM and the LVHL conditions, 3 sets of 7 repetitions at 80% 1-RM. In total, 50 participants completed all testing and were included in analyses.Results: Only LVHL2 improved 30-sec chair stand performance (p?=?.035; g?=?0.89), arm curls (p?=?.011; g?=?1.65) and grip-strength (p?=?.015; g?=?0.34) compared to CON. LVHL2 improved maximal strength compared to CON for 7/8 exercises (p?p?Conclusion: Possibly due to the lower intensity nature of the HVLL conditions, LVHL, twice-weekly was most beneficial for improving functional performance and strength in moderately-highly active older adults. Therefore, we recommend that exercise professionals ensure resistance exercise sessions have sufficient intensity of effort and volume, in order to maximise functional performance and strength gains in older adults. 相似文献
