There are many restrictions placed on researchers studying Paleolithic Cave art due to the constraints of conservation that
limit direct contact with the original works. This paper discusses how recent advances in technology have revolutionized the
study and interpretation of Paleolithic cave art. The interpretation of Paleolithic symbolic systems is a complex process
and hypotheses must be applied to cave art with the greatest of precision. A detailed analysis of the painted or engraved
surfaces leads to a greater understanding of both the techniques employed and the actual sequence in which parietal compositions
were executed. By unlocking the creative process followed by Upper Paleolithic artists we are able to glimpse the artist’s
motivations and to understand a portion of the art’s hidden meaning.

The so‐called global financial safety net provides backstop insurance during financial crises. The three elements of the global safety net — the IMF, regional financial arrangements (RFAs) and bilateral swap agreements — underwent substantial changes after the global financial crisis. How have these changes influenced their use? What role do RFAs have in the safety net? This contribution addresses these questions by examining the timeliness, volume and policy conditionality of liquidity provision of each of the three elements, using a data set of 50 RFA member countries from the period 1976–2015. The article presents case studies of the Arab Monetary Fund (AMF) and the Eurasian Fund for Stabilization and Development (EFSD) to create a deeper institutional understanding of the governance mechanisms of regional funds. The authors find that today's global financial safety net produces inequalities in emergency liquidity provision. In terms of volume, RFAs improve the safety net only for small member countries — about one‐third of the countries in the sample can access sufficient liquidity regionally. The experiences of AMF and EFSD demonstrate that intra‐regional asymmetries of RFAs play a contradictory role: while the participation of large economies leverages liquidity provision, it simultaneously creates difficulties for the governance of the regional body. 相似文献

The article deals with an aspect of the famous German chemist Robert Bunsen which has not been of much notice so far: his journeys. During his stay in Heidelberg (from 1852 on) Bunsen journeyed up to four months a year. Up to the age of seventy-eight, he travelled twice almost every year either in spring or autumn when there were no lectures at the university. He made his journeys for reasons of pleasure and in need of rest from teaching and research. In the 19th century such frequency of travelling was quite unusual even for a bachelor like Bunsen. Beeing an enthusiastic wayfarer Bunsen also travelled far away often, so for example to Italy twelve times (even to Sicily), four times to Scotland and England, and twice to Mallorca. - Bunsen's first nine week journey to Italy in 1843 disappointed him as to its scientific outcome. This journey was a turning-point since he had travelled before for scientific purposes only, beginning with the postdoctoral trip which Bunsen took 1831/32 (sponsored by his sovereign, the king of Hannover) to Berlin, Paris and Vienna for education and information matters. The article sets this journey as well as subsequent travels focusing on science (information, professional communication, experimental team-work) in the framework of continuing academic training. In the end of the 18th and in the 19th century such journeys for further academic education were mainly done at public expense by chemists and geologists as well as by mining and steel scientists to prepare and qualify themselves as either university professors or administrators for mining metallurgical industry. All these various forms of travelling (postdoctoral educational travels at public expense, scientific journeys, meetings for experimental team-work, expeditions, and recreational trips) served the communication within the scientific community. No one who wanted to belong to this community was able to escape such form of communication. 相似文献
