AbstractThe Mystery Room is an educational escape room based on information literacy and applied to multiple audiences, including first-year students and library student employees. In this article, we explain how we developed the game, its theoretical underpinnings, and why it’s a flexible workshop for a variety of audiences. 相似文献

Self‐efficacy pertains to individuals’ belief about their capability to accomplish a task; consequently, school counselors’ positive self‐efficacy is a theoretically based prerequisite for their facilitation of school‐based interventions. In addition, school counselor‐led interventions and comprehensive, developmenta l guidance programs benefit students’ personal social, academic, and career development. Therefore, this investigation examined the contribution of practicing school counselors’ (N = 693) self‐efficacy in relation to the frequency of their programmatic service delivery. The findings indicate that participants’ self‐efficacy scores contributed to the frequency of their programmatic service delivery (48% of the variance explained). Implications for school counselors, supervisors, and educational researchers are discussed. 相似文献

Comparison of oil and egg tempera paint systems using time-of-flight secondary ion mass spectrometry
Zachary E. Voras Kristin deGhetaldi Brian Baade Eric Gordon Glenn Gates Thomas P. Beebe 《文物保护研究》2016,61(4):222-235
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is quickly becoming a critical tool in the field of art conservation. This technique provides high-resolution spatial maps of both inorganic and organic components located within cross-sectional samples collected from works of art. With recent advances in surface analysis, ToF-SIMS can now be used to identify specific amino acids present in protein-containing materials as well as fatty acids in drying oils. For example, the detection of the ion fragment associated with the amino acid hydroxyproline can be used to confirm the use of animal glue in a paint sample. As an analytical technique, ToF-SIMS avoids the need for derivatization/silylation reagents, with no interference by the presence of pigments. Furthermore, the layered systems that are often encountered in historical paint samples remain intact throughout the analytical procedure. This allows for the co-localization of organic and inorganic species in specific layers (e.g. egg yolk paint atop a glue ground). Because of this ability to localize the analytical signal to approximately 6?µm or less, the mass spectral information can be used to produce mass-resolved and spatially-resolve images which can be correlated to previous studies of the same samples. In this study, ToF-SIMS was used to analyze a paint cross section obtained from a painting attributed to Raphael, and another from a painting by the Sienese artist Matteo di Giovanni. 相似文献

When 1,000 words is worth a picture (or story) Every dog has his day.And evidently, so does every minuscule detail of modern society, including the cliché.Not to beat around the bush about it; we’ll just come right out and tell you that, as hard as this fact may be to swallow, today is National Cliché Day. 相似文献
