Since the late 1980s, education systems have increasingly moved to allocating funding for general education by means of a per-student formula. The trend started with developed economies and moved to transition and developing economies, where the World Bank has promoted the adoption of per-student funding (PSF). But promoting a particular reform, such as PSF, by including it in a package of sector-specific development projects funded by World Bank grants or loans, and employing local and international specialist staff do not guarantee successful implementation. This paper examines experience with implementing PSF to school level in transition countries, comparing varying degrees of success to date (2013) in Bulgaria, Moldova and Kosovo. The paper considers the dilemmas inherent in designing PSF formulae for schools, how this played out in each of the countries and the reasons for varying success in implementation. 相似文献

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

ABSTRACTMechanical 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

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

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
