Fluctuations in the financial welfare of institutions of higher education have long been tied to our country’s economic well-being. For many institutions the most recent financial downturns have led to historic revenue and enrollment difficulties that have necessitated the use of cost containment strategies to conserve dwindling resources. Included in these tactics are resource allotment decisions that reflect administrative favor towards some academic departments, leading to the development of a prestige-based stratification system and competition driven funding. A case study of a non-research based institution is used to take a preliminary look at the impact of institutional resource conservation on intra-departmental competition for resources and disparate funding allocations across disciplines in this setting. Special attention is given to the trends in enrollment and the selection of particular academic majors that have occurred across time and in response to the institution’s continued fiscal difficulties. 相似文献

Programming is an essential skill that many computing students are expected to master. However, programming can be difficult to learn. Successfully interpreting compiler error messages (CEMs) is crucial for correcting errors and progressing toward success in programming. Yet these messages are often difficult to understand and pose a barrier to progress for many novices, with struggling students often exhibiting high frequencies of errors, particularly repeated errors. This paper presents a control/intervention study on the effectiveness of enhancing Java CEMs. Results show that the intervention group experienced reductions in the number of overall errors, errors per student, and several repeated error metrics. These results are important as the effectiveness of CEM enhancement has been recently debated. Further, generalizing these results should be possible at least in part, as the control group is shown to be comparable to those in several studies using Java and other languages. 相似文献

Unhealthy diets, lack of fitness, and obesity are serious problems in the United
States. The Centers for Disease Control, Surgeon General, and Department of
Health and Human Services are calling for action to address these problems.
Scientists and educators at Baylor College of Medicine and the National Space
Biomedical Research Institute teamed to produce an instructional unit,
“Food and Fitness,” and evaluated it with students in grades
3–7 in Houston, Texas. A field-test group (447 students) completed all
unit activities under the guidance of their teachers. This group and a
comparison group (343 students) completed pre and postassessments measuring
knowledge of concepts covered in the unit. Outcomes indicate that the unit
significantly increased students'' knowledge and awareness of science
concepts related to energy in living systems, metabolism, nutrients, and diet.
Pre-assessment results suggest that most students understand concepts related to
calories in food, exercise and energy use, and matching food intake to energy
use. Students'' prior knowledge was found to be much lower on topics related
to healthy portion sizes, foods that supply the most energy, essential
nutrients, what “diet” actually means, and the relationship between
body size and basal metabolic rate. 相似文献

Organizations are facing increased pressure from various stakeholders to address issues of sustainability, resulting in a growing demand for sustainability education and training. Procurement groups remain the key drivers of many sustainability‐related strategies, placing pressure on universities to integrate sustainability concepts into the business curriculum. This article describes a replicable educational model that allows students to learn about sustainable procurement while concurrently promoting sustainability within the university community. 相似文献

While 10% of the general population is left-handed, 27% of professional baseball pitchers are left-handed. Biomechanical differences between left- and right-handed college pitchers have been previously reported, but these differences have yet to be examined at the professional level. Therefore, the purpose of this study was to compare pitching biomechanics between left- and right-handed professional pitchers. It was hypothesised that there would be significant kinematic and kinetic differences between these two groups. Pitching biomechanics were collected on 96 left-handed pitchers and a group of 96 right-handed pitchers matched for age, height, mass and ball velocity. Student t-tests were used to identify kinematic and kinetic differences (p < 0.05). Of the 31 variables tested, only four were found to be significantly different between the groups. Landing position of the stride foot, trunk separation at foot contact, maximum shoulder external rotation and trunk forward tilt at ball release were all significantly greater in right-handed pitchers. The magnitude of the statistical differences found were small and not consistent with differences in the two previous, smaller studies. Thus, the differences found may be of minimal practical significance and mechanics can be taught the same to all pitchers, regardless of throwing hand. 相似文献
