OBJECTIVES To create a virtual laboratory system in which experimental science students could learn required skills and competencies while overcoming such challenges as time limitations, high cost of resources, and lack of feedback often encountered in a traditional laboratory setting. DESIGN A blended learning experience that combines traditional(More)
This paper focuses on the validation of the Spanish form of the Eating Attitudes Test (EAT-26; Garner, Olmsted, Bohr & Garfinkel, 1982) across two studies. Participants in Study 1 were 778 females recruited from community settings (aged 12-21). Study 2 included 86 females recruited from clinical and 86 females from community settings (aged 12-35).

The authors derive a general equation to compute multiple cut-offs on a total test score in order to classify individuals into more than two ordinal categories. The equation is derived from the multinomial logistic regression (MLR) model, which is an extension of the binary logistic regression (BLR) model to accommodate polytomous outcome variables.

For m > n > 0, a map f between pointed spaces is said to be a weak n;m]-equivalence if f induces isomorphisms of the homotopy groups k for n 6 k 6 m. Associated with this notion we give two diierent closed model category structures to the category of pointed spaces. Both structures have the same class of weak equivalences but diierent classes of brations(More)
The Eating Attitudes Test-40 (EAT-40; Garner & Garfinkel, 1979) is one of the most widely used measures in the field of eating disorders (ED). The factor structure of the EAT-40, as well as the optimal cut-off score to identify subjects with ED, are subjects of debate. Both controversial issues are addressed in the present study. Participants were 95(More)
A challenging objective in monumental stone restoration is to synthesize crack-free silica materials for application as consolidants. Hydrophobicity is also a valuable property for such products; it is important to prevent the penetration of water because water is the main vehicle by which the agents of decay enter the pore structure of the stone. We report(More)
