While there is a considerable body of literature that presents the results of citation analysis studies, most researchers do not provide enough detail in their methodology to reproduce the study, nor do they provide rationale for methodological decisions. In this paper, we review the methodologies used in 34 recent articles that present a " user study "(More)
We investigated whether early hematoma or edema volumes could explain the adverse association between APOE epsilon4 and survival in intracerebral hemorrhage. Among 102 patients, epsilon4 carriers had a higher mortality rate than non-epsilon4 carriers (38 versus 24%, p = 0.05). Nonsurvivors had larger hematoma (75.5 cm3 versus 27.1 cm3, p<0.001) and edema(More)
OBJECTIVE To determine the relationship between the apolipoprotein E (APOE) epsilon4 allele and in-hospital mortality from intracerebral haemorrhage (ICH). MATERIAL AND METHODS Patients admitted to two acute stroke units with ICH were prospectively evaluated and APOE genotyped. In-hospital survival was recorded in 176 patients. RESULTS There were 85 men(More)
Few studies have assessed the frequency of familial clustering in intracerebral hemorrhage (ICH). Of 144 patients with ICH prospectively assessed, 14 (9.8%) had a positive family history of ICH (FH+). Four pedigrees had more than two affected family members. Comparisons between FH+ and FH- probands demonstrated no significant differences in race, age, sex,(More)
Loss of memory and cholinergic transmission are associated with both Alzheimer's disease (AD) and marijuana use. The human brain muscarinic acetylcholine receptor (mAChR), which is involved in memory function and is inhibited by arachidonic acid, is also inhibited by anandamides. Two agonists of the cannabinoid receptor derived from arachidonic acid,(More)
In this study we examined key individual differences variables within a narrative centered learning environment (NLE) called CRYSTAL ISLAND. CRYSTAL ISLAND features a science mystery set on a recently discovered volcanic island where the task is to determine the cause of disease that is spreading among the inhabitants. Eighth graders were tested for(More)
Formative, content-level feedback on student writing has been shown to have positive impacts on both writing and learning outcomes. However, many teachers struggle to provide this type of feedback to large classrooms of students. This paper takes an initial step towards supporting teacher-facilitated feedback through the use of automated and user-directed(More)
