Tools to manage this complexity under dynamic conditions are needed. The dynamic optimization integrated to operator and engineer decision support has a high p...

Transportation impact analysis performed to comply with environmental impact laws (i.e., the California Environmental Quality Act or the National Environmental Policy Act) often focuses on only one perspective about potential impacts. That perspective reflects how automobile drivers view the world because of general traffic engineering practices and how traffic operations are measured using lev...

Abstract Academics worry grade inflation lowers standards; whereas, employers are concerned grades may not distinguish students’ abilities. These concerns dismissed if higher reflect improved academic achievement and inflation. Potential is examined using data from 17,696 classes between 1985 2019 in the College of Agriculture Life Sciences at Texas A&M University. Evidence systemic increas...

AIMS A pilot study was undertaken with the aim of documenting acute skin reactions and 2-year late adverse effects of a five-fraction course of adjuvant whole breast radiotherapy delivered over 15 days after local tumour excision of early breast cancer. MATERIALS AND METHODS Thirty women with early invasive breast cancer aged>or=50 years with a pathological tumour size<3 cm, complete microsco...

BACKGROUND Barrett's esophagus is a premalignant condition that is a risk factor for the development of esophageal adenocarcinoma, a disease whose incidence is rapidly increasing. Because aspirin and other nonsteroidal anti-inflammatory drugs, such as celecoxib, may decrease the risk of developing esophageal cancer, we investigated the effect of long-term administration of celecoxib in patients...

The purpose of the present study was to investigate the word problem solving skills of 47 secondgrade students by examining how they performed on combine, change and compare word problems. The results of the repeated measures ANOVA showed that students scored significantly lower on compare problems than on combine and change word problems. Based on the results of this study, we disproved the hy...

BACKGROUND There is no standard method of measuring change in chronic pain severity. Clinical trials commonly use serial assessment scales, completed at two points in time, to estimate change in pain severity, while clinicians usually ask patients to make a retrospective assessment of change. How the two methods compare is not known. AIM To assess different methods of measuring change in chro...

This study reports the impacts of the Scientific Concept Construction and Reconstruction (SCCR) digital learning system on eighth grade students’ concept construction, conceptual change, and scientific reasoning involving the topic of “atoms”. A two-factorial experimental design was carried out to investigate the effects of the approach of instruction and students’ level of scientific reasoning...
