Bringing the Author Back Into the Audience Research: A Hermeneutical Perspective on the Audience's Understanding of the Author     

Tereza Pavlíčková 《The Communication Review》2013,16(1-2):31-39

In the current media environment the texts available to media audiences are from very diverse sources. This paper deals with a theoretical question of how the audiences' understanding of author co-determines the reader's interpretation of the particular text. Drawing on the tradition of philosophical hermeneutics, a concept of the imagined author is introduced: a result of the text-reader encounter, where the notion of the author suggested by the text is realized by the reader through their prior knowledge and expectations of an author. A multidimensional model of the author is therefore proposed to appreciate different characteristics and values potentially associated by audiences with varying forms of authorial presence. Distinguishing various dimensions of the author allows a matrix of authorial characteristics to be built that positions the author brought into the encounter by the text as a paratextual feature that co-determines the meaning of the text.  相似文献   

Why Do Historical Beeswax Seals Become Brittle Over Time?

ABSTRACT

Mechanical properties of aged beeswax were studied by an indirect measurement, using hydrogenated beeswax as a model material. The adequacy of the model was evaluated by comparison of its chemical composition and thermal properties with those of samples of historical beeswax. It was found that the gradual decrease in content of unsaturated compounds in beeswax contributes significantly to changes of its mechanical properties. As a consequence, beeswax artefacts become increasingly prone to mechanical damage during natural ageing. Understanding the difference between mechanical properties of recent and historical beeswax is primarily important from the point of view of safe handling and storage of such artefacts. Besides, this knowledge could help conservation scientists, e. g. when preparing model samples for testing new conservation methods.  相似文献   

Dubious Early Medieval Jewels from Matzhausen (Bavaria): New Material and Technological Investigations     

Jan Hasil  Estelle Ottenwelter  Ludmila Barčáková 《文物保护研究》2020,65(6):333-345

ABSTRACT

A controversial set of elite jewels assumed to be of early medieval period, recovered in 1937–1938 from a burial site in Matzhausen (northeastern Bavaria) was investigated to determine their technological coherency as well as their authenticity. The discovery of these jewels was exploited by German nationalists to argue that the material culture observed in Bohemia and Moravia in the ninth century had Germanic roots. The circumstances of their discovery, however, remain unclear. Research in archives demonstrated the involvement of the SS Ahnenerbe organisation in the recovery of the jewels. Are these jewels authentic or are they forgeries manufactured or modified by a modern craftsman to serve German expansionist nationalism? Three jewels recovered in the grave – a gombik (hollow spherical pendant), an earring with chainlet, and a zoomorphic figurine – were investigated using scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDX), X-radiography, and stereomicroscopy. The investigation revealed a very heterogeneous set of objects with respect to technology and state of preservation. It also uncovered repairs and past invasive interventions involving modern metal and solder. Comparison with similar types of jewels from Bohemia and Moravia points to important differences in construction and technology, which confirms the uniqueness of this set of objects and casts suspicion on their authenticity.  相似文献   

When Glass and Metal Corrode Together,V: Sodium Copper Formate     

Andrea Fischer  Gerhard Eggert  Robert Dinnebier  Tomče Runčevski 《文物保护研究》2018,63(6):342-355

A sodium copper formate, first described in 2002, can also form on copper alloys with sodium originating from soda glass hydrolysis. The frequent occurrence (50% of 250 cases of glass-induced metal corrosion) is due to the presence of formaldehyde emissions in storage and its direct reaction to formate in the alkaline surface films. The compound can be produced without the presence of acetate when chalconatronite or metal coupons immersed in soda solution are exposed to formaldehyde vapours. The crystal structure, derived from X-ray powder diffraction, yielded the sum formula Cu₄Na₄O(HCOO)₈(OH)₂·4H₂O. Except for the absence of acetate in the structure, this is in good agreement with the 2002 publication. To assess which kind of combined glass/metal objects are affected, a number of large museum collections were surveyed. Sodium copper formate was detected as a corrosion product using mainly micro-Raman spectroscopy, for instance, on 18 painted Limoges enamels, eight glass vessels with metal mountings, glass beads on metal wire from 11 bridal crowns, nine Christmas tree balls with wire decoration, 40 pieces of jewellery with glass gems, three daguerreotypes, and one miniature with cover glasses.  相似文献

Challenges for teachers’ professional learning for inclusive education in Central and Eastern Europe and the Commonwealth of Independent States     

Lani Florian  Majda Becirevic 《Prospects》2011,41(3):371-384

Efforts to prepare teachers and other professionals for inclusive education in the Central and Eastern Europe and the Commonwealth of Independent States (CIS/CEE) region are heavily influenced by the legacy of Soviet defectology (the study of children with disabilities) and Soviet traditions of teacher education. The authors identify some challenges facing those concerned with preparing teachers for inclusive education and provide examples of current projects in the region that address the complex problems associated with providing inclusive education for children identified as having disabilities. The changing role of defectologists in inclusion policy and practice is also discussed. Case examples from Armenia, Latvia, the Czech Republic, Azerbaijan, and Serbia reflect current innovations in teacher education and professional development in the region.  相似文献   

A novel way of liver preservation improves rat liver viability upon reperfusion   总被引：4，自引：0，他引：4  

Kebis A  Kukan M  Grancic P  Jakubovský J 《Journal of Zhejiang University. Science. B》2007,8(5):289-295

Background/aim： Currently, the liver is cold-preserved at 0-4 ℃ for experimental and clinical purposes. Here, we investigated whether milder hypothermia during the initial phase of the preservation period was beneficial for liver viability upon reperfusion. Methods： In the first set of experiments, rat livers were preserved either conventionally in clinically used histidine-trypthopan-ketoglutarate （HTK） solution （Group A： 45 min and Group B： 24 h） or by slow cooling HTK solution （from 13 ℃ to 3 ℃） during the initial 45 min of preservation （Group C： 24 h）. In the second set of experiments, additional groups of livers were evaluated： Group BB-preservation according to Group B and Group CC-preservation according to Group C. Further, some livers were preserved at 13 ℃ for 24 h. Livers were then reperfused using a blood-free perfusion model. Results： Bile production was approximately 2-fold greater in Group C compared to Group B. Alanine transaminase （ALT） and aspartate transaminase （AST） release into perfusate were 2-3-fold higher in Group B compared to Group C. No significant differences were found in ALT and AST release between Group C and Group A. Livers in Group CC compared to Group BB exhibited significantly lower portal resistance, greater oxygen consumption and bromosulfophthalein excretion into bile and lower lactate dehydrogenase （LDH） release into perfusate. Histological evaluation of tissue sections in Group BB showed parenchymal dystrophy of hepatocytes, while dystrophy ofhepatocytes was absent in Group CC. Livers preserved at 13 ℃ for 24 h exhibited severe ischemic injury Conclusion： These results suggest that the conventional way of liver preservation is not suitable at least for rat livers and that slow cooling of HTK solution during the initial phase of cold storage can improve liver viability during reperfusion.  相似文献   

Learning habits of students with special needs in short‐term vocational education programmes     

Majda Schmidt  Helena Čreslovnik 《Educational studies》2010,36(4):415-430

This research examined some characteristics of the learning habits of students with special needs and those without them in programmes of short‐term vocational education in five areas: motivation, learning and learning techniques, emotional, social and the area of self‐evaluation. The research sample consisted of 140 students from different secondary schools. The Questionnaire on the Learning Habits of Adolescents was used for the purpose of the study. The differences between the means from individual learning habit scales, between the students with special needs or without them, were discovered by one‐way analysis of variance. Basic findings of empirical research emphasise that there exist statistically significant differences between the students with special needs and the students without special needs in four areas of learning habits. Among the findings causing concern in connection with learning habits, we would like to underscore the fact that students with special needs are perceived as less efficient at and less competent in coping with learning and work tasks. These students are not familiar with effective methods and strategies for successful learning, which leads to the feelings of frustration and helplessness in case of failure. In order to cultivate an effective and supportive educational environment for students with special needs, short‐term vocational schools should develop learning/teaching models that provide a potentially powerful alternative to traditionally directed teaching approaches.  相似文献
