A re-united pair: The conservation,technical study,and ethical decisions involved in exhibiting two terracotta orante statues from Canosa     

Susan D. Costello 《文物保护研究》2014,59(6):377-390

The collection of the Worcester Art Museum includes two rare Magna Graecia terracotta funerary statues from Canosa, Italy dating to the third century BCE. Each depicts a female figure in prayer or lament known as an orante. The orantes were purchased by the museum in 1927, but shortly thereafter were separated. One was left in storage for nearly seven decades and the other was sold, and ultimately entered a private collection halfway around the world. The orantes were recently reunited under serendipitous circumstances and, after more than 80 years, will finally be placed on display at the Museum. As part of a comprehensive treatment, a technical study was carried out to identify the materials and methods used in their manufacture and in previous restoration campaigns. Materials were characterized by cross-section analysis, spot tests, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), neutron activation analysis (NAA), thermogravimetric analysis (TGA), thermoluminescence (TL) dating, and reflectance transformation imaging (RTI). The analytical findings helped inform the conservation treatments, which included structural work, surface cleaning using a Nd:YAG laser, and esthetic reintegration.  相似文献   

The Roles of Engagement at The Ohio State University Libraries: Thoughts from an Early Adopter     

José O. Díaz 《The Reference Librarian》2014,55(3):224-233

Changes in information and technology continue to test how librarians interact with and support patrons. Now, engaged librarians have the opportunity to immerse themselves in their user’s workflows and become partners in the research enterprise. Engagement represents a model of librarianship in which librarians are challenged to move from the traditional collection-centered model to an engaged-focused one. It requires new roles and tasks, as well as a deeper understanding of the academic setting. This article discusses working in a large research institution and articulates the engagement model.  相似文献   

Effects of manipulating relative and absolute motion information during observational learning of an aiming task.

In the visual perception perspective of observational learning, the manipulation of relative and absolute motion information in visual demonstrations optimally directs learners' search towards appropriate task solutions. We assessed the effect of emphasizing transformational information and removal of structural information using point-light kinematic displays in approximating the model's relative motion patterns. Participants viewed computer-simulated point-light demonstrations or normal video demonstrations before and intermittently throughout 100 acquisition trials with knowledge of results on an underarm modified-dart aiming task. On the next day, all participants performed 20 retention trials without demonstrations. The kinematics of spatial and temporal coordination and control variables were examined relative to the model's action, as well as performance scores. The results indicated that approximation of the model's spatial and temporal coordination and control patterns was achieved after observation of either type of demonstrations. No differences were found in movement outcomes. In a second experiment, the effects of manipulating absolute motion information by slow-motion demonstrations were examined relative to real-time demonstrations. Real-time demonstrations led to a closer approximation to the model's spatial and temporal coordination patterns and better outcome scores, contradicting predictions that slow-motion displays convey intact relative motion information. We speculate that the effect of visual demonstration speed on action perception and reproduction is a function of task constraints--that is, novelty or familiarity of relative motion of demonstrated activities.  相似文献   

The Reading–Spelling Connection: Developing and Evaluating a Beginning Spelling Intervention for Children at Risk of Reading Disability     

Lana Edwards Santoro  Michael D. Coyne  Deborah C. Simmons 《Learning disabilities research & practice》2006,21(2):122-133

Abstract In this article, we describe the development and evaluation of a beginning spelling intervention for young children at risk of reading disability. We first summarize the literature that supports beginning spelling as an ideal method for strategically integrating the beginning reading big ideas of phonemic awareness and alphabetic understanding. We then summarize the literature on effective instructional principles for students at risk of reading disability. Next, we describe how instructional design was applied to the development of an intervention for young children at risk of reading disability, then summarize the findings of an experimental study supporting the effectiveness of this intervention. Finally, we provide selected examples from the spelling intervention to illustrate the findings' translation into instructional practice.  相似文献

Examining the specificity of practice hypothesis: is learning modality specific?     

J Coull  L Tremblay  D Elliott 《Research quarterly for exercise and sport》2001,72(4):345-354

The specificity of practice hypothesis was examined using a tracking task. In Experiment 1, visual or auditory feedback about performance was provided. Vision was more useful than audition early in acquisition. Performance gains found in acquisition were maintained during retention, but learning was specific only if the acquisition modality was visual. Specificity did not increase with the amount of practice. In Experiment 2, visual and auditory information were combined. Again, the specificity of practice hypothesis was supported. Also, instructing participants to attend to one information source allowed us to demonstrate that information can be explicitly or implicitly processed. Further, specificity effects may occur because of different rates of development for error detection and correction processes.  相似文献

A simultaneous model of nonprofit symphony orchestra behavior     

William A. Luksetich  Mark D. Lange 《Journal of Cultural Economics》1995,19(1):49-68

In this paper, we test a six equation simultaneous model of nonprofit symphony orchestra behavior. The model is based on Hansmann's theory of nonprofit behavior in the performing arts. The results show that the most prestigious of the orchestras practise a pricing policy that encourages patrons to make a tax deductible contribution. In this manner, they achieve a pattern of price discrimination that, instead of increasing revenues, reduces revenues. Following conditions suggested by Hansmann, we are also able to draw conclusions about the objectives of nonprofit symphony orchestras.  相似文献
