Adaptations and Dispersals of Anatomically Modern Humans in the Changing Environments of North Africa: the Contribution of Microvertebrates

There is limited available data on the environmental context of the arrival of the first anatomically modern humans (AMH) in North Africa, and subsequent Paleolithic and Neolithic occupations within this region. Microvertebrates such as rodents, shrews, amphibians, and squamates are known to be good indicators of climate and landscape changes. They also represent continental paleoecological records that can be directly related to human occupations. Moreover, faunas and humans have been subjected to several dispersal waves through similar routes, and some rodents may present anthropophilous behavior. Therefore, by understanding the dispersal pattern and pathways of these microvertebrates, it is possible to propose scenarios for human dispersal events. In this study we took the rich microfaunal assemblages from the Témara region, Atlantic Morocco (El Harhoura 2 and El Mnasra Caves), and placed them within a broader synthesis, in order to highlight the role of microvertebrates in providing a better understanding of the human-environment relationship during the Late Quaternary in North Africa.     

The Pleistocene of Rabat (Morocco): Mollusks,Coastal Environments and Human Behavior

The Rabat-Témara region of the Moroccan Atlantic coast reveals a succession of Quaternary palaeobeaches. This coastal area is dotted with numerous prehistoric caves. The study of the Upper Pleistocene coastal landscape associated with these caves is of paramount importance in the knowledge of human population subsistence. During the Upper Pleistocene, the ocean level changes drastically influenced the coastal geomorphology as well as the fauna assemblages. The chrono-lithostratographical analysis of the coastal sedimentary formations allows the distinction of three sequences rich in marine fauna. These sequences date from MIS 11 to MIS 5. The identification of malacofauna species from these deposits revealed 39 species, along with Bryozoans, Crustaceans, and Echinoids. These assemblages show a constant fauna cortege highlighted by the dominance of the amphi-Atlantic species Stramonita haemastoma. This species shows an increase in the number of specimens in the uppermost part of marine deposits, probably in relation with a climate warming in the MIS 5. This fauna of both intertidal rocky substrates and sandy substratum indicates environmental conditions close to the present-day Rabat-Témara coastline. As in other coastal locations of Africa from MIS 5, the Middle Stone Age Homo sapiens population benefitted from a littoral environment rich in coastal resources. Comparison between thanatocenoses and archaeological records allows us to identify both species available for Middle Stone Age population and those preferred for human use.     

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.     

The reflection of human activity in the sediments of Iwankowskie Lake from Subatlantic Phase (Polish Outer Carpathians)

The paper presents the analysis of organic and mineral sediments filling the depression, which developed over the landslide located at the slope (767–773 m a.s.l.) of Lubań ridge decscending to the Ochotnica river valley in the Polish Flysch Carpathians. The landslide formed in an early stage of the Subatlantic Phase (2490 ± 35 BP). The top of peat is dated at 1360 ± 50 years BP and is covered by 72 cm of clayey silts with some sandy intercalations, which indicate slopewash after deforestation. The pollen of ruderal plants and Cerealia (undiff.) reflect agricultural activity in the surroundings. The fragments of charcoal indicate the age of the forest clearance to the first half of the 17^th century. The late forest clearance at the elevated north exposed slopes followed 200–300 years later in relation to the foundation of the village at the valley floor.     

Einstein et «Zweistein»

As the sobriquet «Zweistein» suggests, within the theoretical physics community Wolfgang Pauli came to be regarded as second in eminence only to Albert Einstein. Over a period of thirty-five years, they interacted both intellectually and personally. This paper focuses on four interrelated topics of their discussions. 1) The theory of relativity: at the age of twenty, Pauli prepared the definitive survey of relativity, a survey which he revised near the end of his life and which remains invaluable to physicists and historians of physics. 2) Unified field theories: although initially sympathetic to Einstein's search for a unified theory of electromagnetism and gravitation, and having made important contributions to the subject, Pauli came to regard such efforts as fruitless. 3) Foundations of quantum mechanics: Pauli's negative evaluation of Einstein's program grew out of their sharply differing evaluations of the role that quantum mechanics would play in the future, development of theoretical physics. 4) Quantum gravity: Pauli recognized that, until the achievement of a successful reconciliation of quantum mechanics and general relativity — an achievement that still eludes us — Einstein's challenge to quantum mechanics could not be laid to rest.     

The Archaeology of Regions: From Discrete Analytical Toolkit to Ubiquitous Spatial Perspective

In the 1970s and 1980s, regional analysis was an influential part of archaeological research, providing a discrete set of geographical tools inspired by a processual epistemological and interpretive perspective. With the advent of new technologies, new methods, and new paradigms, archaeological research on regional space has undergone significant changes. This article reviews the state of regional archaeology, beginning with a consideration of its history and a discussion of the fundamental issues facing regional investigations before focusing on developments over the last several years. On one hand, the diversification of archaeological theory has created new paradigms for thinking about human relationships with one another and with the physical environment across regional space; in this regard, historical ecology, landscape archaeology, and evolutionary theory have been particularly influential in recent years. This has led to a corresponding diversification of the traditional methods of regional analysis. Most notably, the advent of powerful digital technologies has introduced new tools, especially those from the geographic information sciences, that build on the quantitative methods of past approaches. The investigation of regional data is no longer based on a discrete toolkit of simple mathematical and graphical procedures for representing spatial relationships. Instead, regional archaeology has matured into a diversity of multiscalar spatial and geostatistical techniques that inform many areas of archaeological inquiry.
