A TREASURE TROVE OF CHRONOLOGICAL LEARNING

The recent facsimile edition of Henricus Glareanus's Chronology of Livy, prepared by Anthony T. Grafton and Urs B. Leu, provides access to a primary source that is unique from the point of view of the history of science and scholarship and of the book and reading. The basis of the edition, a copy of Chronologia annotated by Glareanus's disciple Gabriel Hummelberg II, now preserved at the Princeton University Library, serves scholars both as a point of departure for outlining hypotheses on the teaching methods of early modern humanists as well as the role of chronology in the humanist curriculum. My reading of their edition is based on three points. First, I put the primary source of their choice in a context that includes provincial early modern educational centers as I believe that their enterprise could clear the way for future narratives on forgotten scholars who dealt with the issues of technical chronology. Second, I show the importance of Grafton and Leu's thesis on the procedures of transmission of teachers’ commentary, which, according to them, is documented by the Princeton copy of Chronologia. Third, I argue that the seemingly conservative decision to publish a paper edition of an annotated volume at the moment when state‐of‐the‐art digital tools for such editions are being tailored through the alliance of scholars and IT specialists should open a discussion among historians of the book and reading, science, and education that would lead to the determination of standards for scholarly editions of libri annotati.     

Clusters versus Cluster Initiatives,with Focus on the ICT Sector in Poland

The article focuses on the topic of clustering, which has become a popular concept, both from the academic and political perspective, and as an efficient business model. The distinction between clusters, understood as geographical concentrations of specific industries, and cluster initiatives, understood as more formalized actions undertaken by regional actors, is proposed. The primary objective of this study is to verify if these two types of structures are overlapping each other. This problem arises because the motivation for forming some cluster initiatives may be different economic policy instruments rather than existing market potential of a specific regional economy. The study finds that not all of Information and Communication Technologies (ICT) cluster initiatives in Poland represent real concentration of ICT-related divisions included in statistical classification of economic activities in the European community Rev. 2 classification, as measured by location quotients (LQs) for indicators on employment, firms' incomes and number of enterprises. However, there is a visible pattern that the LQs are higher in smaller geographic areas (NUTS 4 (Nomenclature of units for territorial statistics)), which usually represent big cities, being the cores of cluster initiatives. The study also discusses the phenomenon of the internationalization of clusters and the value added to that process from forming formalized cluster initiatives, which create favourable institutional framework for transborder cooperation.     

Guy D’Arezzo et « Notre Notation Musicale Moderne »

In his Sociology of music, Max Weber stressed the importance of the invention of notation on lines by Guido of Arezzo (c. 990–1035). This article traces the beginnings of musical notation. Although Guido of Arezzo proposed a system of lines in which each note is always in the same place, he also placed the neumes invented before him on these lines. The first annotators sought to note with precision the rhythmic nuances and ornaments of the melodies; but those subtle indications disappeared little by little from the notation, betraying an inflexibility of the tradition, which contributed to the orientation of western music towards paths which did not know other music of oral tradition.     

Climate change adaptation of the tourism sector in the Bolivian Andes

Over the last 40 years, warmer temperatures have caused a considerable decrease in snow cover on glaciers and high rates of glacial melt, particularly in tropical mountains. In the Bolivian Andes, the Chacaltaya glacier (5400 masl) had been a tourist destination known as the highest ski slope in the world since 1939. As a result of climate change, skiing has not been possible after 1987 and the glacier definitely disappeared in 2009. However, since 2005, the place has become a new attraction for tourists. Travel agencies in La Paz now offer day trips to the Chacaltaya site. In order to understand the present attraction of the site and its potential for reproduction elsewhere, 25 semi-structured interviews were conducted with various categories of stakeholders involved in the tourism industry in La Paz, and archives and images were analysed. Our results show that the multifunctional character of this tourist site, including easy access to a summit, beautiful views, acclimatisation to altitude and opportunity to experience snow, are key factors in its renewed attraction for visitors, together with, to a lesser extent, the incentive of being able to watch a famous and evident full disappearance of a glacier and former ski slope. The stakeholders' groups share general views and perceptions about environmental changes and about the qualities of the site, but they also differ in terms of projects and evaluation of potential attractiveness. In particular, the development of the visibility of climate change impacts on mountain environment is valued by experts or by members of the Andean Club, but not by travel agencies. The example of Chacaltaya shows that multifunctional tourist sites may still be attractive in the future.     

Strontium isotopic characterization of the Palmottu hydrosystem (Finland): water–rock interaction and geochemistry of groundwaters

The Palmottu hydrosystem is located in a granitic host rock in southern Finland. Along well‐defined pathways in the fractured crystalline rock, strontium isotopes are used to trace the degree of water–rock interaction (WRI) and mixing processes in groundwaters. The ⁸⁷Sr/⁸⁶Sr ratios range between 0.716910 and 0.735606 in the surface waters and between 0.719991 and 0.750787 in the groundwaters, but are between 0.720 and 0.735 in most of the samples. Moreover, the results show a lack of correlation between the water chemistries determining the classification into different water‐types (Na–Cl, Na–SO₄, etc.) and the results of the strontium (Sr) contents and Sr isotopic ratios. From a WRI standpoint, this implies that the Sr behaviour is independent of the water chemistry; the occurrence of large ⁸⁷Sr/⁸⁶Sr variations is site specific and mainly dependent on the lithology. A model to determine the ⁸⁷Sr/⁸⁶Sr ratio of water after interaction with granite was developed. This model is based on the assumption that Sr was derived from three minerals: plagioclase, K‐feldspar and biotite. The results of the calculation indicate that around half of the water analysed within the Palmottu hydrosystem can be explained by the weathering of the granites. However, clearly lower ⁸⁷Sr/⁸⁶Sr are observed in waters when compared to the calculated ⁸⁷Sr/⁸⁶Sr and other sources of Sr, with low ⁸⁷Sr/⁸⁶Sr, rather than the calculated granite–water interaction, which may be suspected. When comparing the ⁸⁷Sr/⁸⁶Sr and ion ratios (Ca/Na, Mg/Na, Sr/Na, Cl/Na), the scattering of the data can be explained by the presence of four end‐members: a brine component (low ⁸⁷Sr/⁸⁶Sr and Ca/Na ratios…), a deep granitic component (high ⁸⁷Sr/⁸⁶Sr ratios and low Ca/Na ratios…), a subsurface component (intermediate ⁸⁷Sr/⁸⁶Sr ratios associated with high Ca/Na ratios…) and a surface end‐member:snow and river drainage (low ⁸⁷Sr/⁸⁶Sr and low Ca/Na ratios…). These extreme end‐members define a series of WRI‐mixing line within a rather complex hydrosystem.
