ABSTRACT This article presents historical and scientific analysis, as well as the conservation treatment of a newly rediscovered Roman wall painting fragment, now in the collection of the Harvard Art Museums. Although the piece has not previously been published, it was among a group of fragments removed from a Roman villa near Boscotrecase in southern Italy, an area that has been key to the study of Roman wall painting and other decoration. Technical imaging confirms the use of painting techniques consistent with other high-quality paintings in the area. Materials analysis revealed a palette consistent with published findings of Roman wall paintings, including abundant use of Egyptian blue and green earth. Of interest was the use of Egyptian blue as an optical brightener in select white passages. Despite the high quality of the painting, no cinnabar was present, and all red passages were achieved using hematite. Multiple different white minerals were identified including calcite, aragonite, and gypsum. The widespread presence of gypsum is unusual and may point to alteration. 相似文献

This article describes a current project by Liverpool organisations Open Eye Gallery (Liverpool), Whitby High School (Ellesmere Port), recent partners Liverpool Hope University and Curious Minds. The school is in an area of high socio‐economic deprivation and low level of cultural engagement. The project seeks to support students’ photographic and digital skills, using co‐authored approaches to learning to raise young people’s overall aspiration levels. This article addresses conflicts / ethics of photography, social media and the digital in creative education today but ultimately seeks to champion photography as a tool for increased visual literacy when co‐authored between both school and cultural organisation. 相似文献

Mission statements have been a staple of higher education institutions for decades, but little is known of how they are used as a tool for institutional decision-making. Using three distinct data sources, this study relies on framing theory to analyse the perceptions of university presidents in the United States on the role of mission statements in deciding when and how to communicate. Further, we compare the espoused values of university mission statements to the statements university presidents made following the 2016 US presidential election. Findings indicate presidents view mission statements as central to their decision to communicate and our analysis reveals some congruence between mission statements and public statements. 相似文献

Research suggests body image is related to sexual behaviors, which can impact sexual health across the lifespan. This paper aims to explain the necessity for including body image content in sexuality education to improve outcomes among girls. Our recommendations, supported by theory and empirical research include (a) an assessment of existing curricula; (b) designing new, theoretically-informed curricula; (c) using innovative technology in sex education; (d) rigorous evaluation of existing and new curricula; and (e) revising the National Sexuality Education Standards. These recommendations are discussed after providing the necessary background and rationale. 相似文献

Development of new methods for anatomy teaching is increasingly important as we look to modernize and supplement traditional teaching methods. In this study, a life-sized equine model, “Geoff,” was painted with surface and deep anatomical structures with the aim of improving students’ ability to convert theoretical knowledge into improved topographical anatomy knowledge on the live horse. Third and fourth year veterinary medicine students (n = 45) were randomly allocated into experimental (used “Geoff”) and control (used textbook) groups. The efficacy of the model was evaluated through a structured oral exam using a live horse. Questionnaires gathered information on student confidence and enjoyment of the task. There was no significant difference in the performance of experimental and control groups either immediately (44±20% vs. 40±21%; P = 0.504) or 9 weeks after the learning intervention (55±17% vs. 55±20%; P = 0.980). There were however specific questions on which the experimental group performed better than controls, and for which gender effects were apparent. The students using “Geoff” showed a transient gain in confidence following the session (Likert scale 2.7 to 3.6) however the initial increase was no longer present at the second test. There was a significant influence of gender on confidence with greater confidence gains in females in the Experimental group. The students found the model to be extremely useful and both groups found the sessions enjoyable. The model will be of benefit as a complementary learning tool for students. 相似文献

Although it remains rare in the United States, planned home birth has drawn increasing attention and criticism in the mainstream media and has come under attack from organized medicine. Yet, recent peer-reviewed studies contribute to the evidence base supporting home birth as a safe option for low-risk women attended by skilled midwives. The author of this editorial argues that home birth is an important cultural touchstone in the landscape of American maternity care. 相似文献

OBJECTIVE: Although maternal internalizing symptoms and parenting dimensions have been linked to reports and perceptions of children's behavior, it remains relatively unknown whether these characteristics relate to expectations or the accuracy of expectations for toddlers' responses to novel situations. DESIGN: A community sample of 117 mother-toddler dyads participated in a laboratory visit and questionnaire completion. At the laboratory, mothers were interviewed about their expectations for their toddlers' behaviors in a variety of novel tasks; toddlers then participated in these activities, and trained coders scored their behaviors. Mothers completed questionnaires assessing demographics, depressive and worry symptoms, and parenting dimensions. RESULTS: Mothers who reported more worry expected their toddlers to display more fearful behavior during the laboratory tasks, but worry did not moderate how accurately maternal expectations predicted toddlers' observed behavior. When also reporting a low level of authoritative-responsive parenting, maternal depressive symptoms moderated the association between maternal expectations and observed toddler behavior, such that, as depressive symptoms increased, maternal expectations related less strongly to toddler behavior. CONCLUSIONS: When mothers were asked about their expectations for their toddlers' behavior in the same novel situations from which experimenters observe this behavior, symptoms and parenting had minimal effect on the accuracy of mothers' expectations. When in the context of low authoritative-responsive parenting, however, depressive symptoms related to less accurate predictions of their toddlers' fearful behavior. 相似文献

This paper discusses how expert guidance can be best provided in work intensive clinical settings. The adequacy for supporting
learning in the clinical practicum for health care disciplines is often complicated by the intensive work practices in healthcare
settings. Often, clinicians’ work is so intense that the scope for providing close guidance for students is quite restricted.
The case advanced here draws on a range of empirical work to propose how clinician-student interactions might be optimized
through the provision of a clinical supervisor to assist clinicians develop collegial relationships and acquire skills in
guided learning such as demonstrating and role-modeling. These roles can contribute in essential ways to the development of
learning environments where clinicians have the opportunity to facilitate the learning of others as part of their workload,
and without being burdened by the requirements of teaching and assessment processes. It differs from other approaches because
although clinicians partner students and provide feedback to them, clinicians are not expected to formally assess or award
a grade for student performance. Assessment and remedial action, when required, is undertaken by the role of a designated
clinical supervisor qualified to perform such activities. 相似文献
