SHAFT‐HOLE AXES FROM SLOVENIA AND NORTH‐WESTERN CROATIA: A FIRST ARCHAEOMETRIC STUDY ON ARTEFACTS MANUFACTURED FROM META‐DOLERITES*

A group of Copper Age shaft‐hole axes from Caput Adriae (northeastern Italy, western Slovenia and northwestern Croatia) manufactured using meta‐dolerite have been analysed for major and trace elements. All the samples show magmatic textures and well recognizable relicts of primary mineralogical phases. Petrographic observations suggest an ophiolitic provenance of the protolithic source(s) while geochemical data indicate that the original magmas originated in a fore arc or pre arc tectonic setting. Strong similarity has been found with several lithotypes from the Banija Ophiolite Complex (Croatia), here indicated as the most probable source area. Considering the available archaeometric data about shaft‐hole axes found in northern Italy and Caput Adriae in comparison to those of axe blades discovered in the same area, it emerges that there is a utilization of different rock types, the source of which appears to be quite close to the discovery sites. In the investigated area the shaft‐hole axes are largely made from ophiolitic‐related rocks which are associated with copper deposits. Consequently there may have been a relation between the localization of the geological sources of shaft‐hole axes and the development of metallurgical activities.     

MANGANESE STAINING OF ARCHAEOLOGICAL GLASS: THE CHARACTERIZATION OF Mn‐RICH INCLUSIONS IN LEACHED LAYERS AND A HYPOTHESIS OF ITS FORMATION

During the study of a large number of archaeological glass fragments, manganese‐rich inclusions in leached layers were observed in a limited number of cases. This phenomenon occurs only in black‐coloured leached layers. Since the formation mechanism of such manganese‐rich inclusions is still unclear, a combination of several analytical techniques was used in order to investigate this phenomenon and, more specifically, to obtain more information on (a) the composition and morphology of the inclusions, (b) the chemical state of Mn and (c) the 3D morphology of the inclusions. A mechanism that might explain the formation of these inclusions is proposed.     

TESTING ANALOGICAL TAPHONOMIC SIGNATURES IN BONE BREAKING: A COMPARISON BETWEEN HAMMERSTONE‐BROKEN EQUID AND BOVID BONES

Current analogical data used to infer prehistoric human bone breakage rely on a plethora of experimental hammerstone‐broken bovid bone sets. Several criteria have been argued to be diagnostic of bone breakage by humans, among which the most important are: a specific range of broken specimens bearing percussion marks, a specific distribution of different percussion mark types, metric properties of notches, differential notch type distribution, and the angle of oblique breakage planes. The present work shows that those properties derived from the breakage of bovid bones cannot be universally applied to all types of animals. As an example, here it is experimentally demonstrated that hammerstone‐broken equid bones (with different thickness and structural properties compared to bovid bones) show different values in all these variables and some of them overlap with criteria documented in bones broken by static loading. This suggests that the agents of equid bone breakage are more difficult to identify, and that the number of variables that can be successfully used to that end is smaller than in bovid bones.     

Protecting aquatic ecosystems in heavily allocated river systems: the case of the Oldman River Basin,Alberta

Initiatives aimed at protecting aquatic ecosystems often prove difficult to implement—particularly in water‐stressed, semi‐arid regions where the demand for water for human consumption is high. This article reports on an investigation of the factors that shaped the development and implementation of policies for aquatic ecosystem protection in the Oldman River Basin (ORB), a crucial watershed in semi‐arid southern Alberta. The analysis reveals critical cultural and historical considerations that confront those attempting to protect and restore aquatic ecosystems in the ORB and highlights specific factors that influence implementation of measures to protect it. In addition to the most basic consideration—demand for water exceeds supplies—eight specific factors that influenced aquatic ecosystem protection in this region are identified and evaluated. These include (1) clarity of actors’ roles/ jurisdictional responsibilities; (2) communication; (3) definition of key terms; (4) funding and organizational capacity; (5) leadership; (6) legal standing; (7) data and monitoring; and (8) public education. We argue that while these factors are important, critical cultural and historical considerations that influence water policy in the province also must be addressed in any efforts to protect aquatic ecosystems in southern Alberta.     

PHILOSOPHY OF HISTORY AFTER 1945: A BIBLIOMETRIC STUDY

Much has been said about what philosophy of history should be. This bibliometric assessment of research in the philosophy of history examines what scholars in this field have actually produced. The study covers a dataset—a subsection of the bibliography of the International Network for Theory of History—of 13,953 books, articles, book chapters, dissertations, and other scholarly publications, encompassing materials written in seven different languages published between 1945 and 2014. This material was classified according to a multilayered system of taxonomy consisting of keywords representative of themes discussed in the field. Separate quantitative analyses were made to elucidate characteristics about the publication outputs in the field in the different language groups. Changes in paradigm, often referred to as “turns” or “trends,” have been mapped in this study, according to a quantitative analysis of the most recurrent keywords within a five‐year interval, which give an indication of the most debated themes in each period. ?Religion/theology/secularization? is the most frequent keyword during the period 1945 to 1969, followed by ?Marxism/historical‐materialism?¹ from 1970 to 1984, in what can be considered a second period of the field. Although many of the key publications of the linguistic turn were written within this second period, our dataset shows that it is not until the third period (1985–2014) that their writing goes on to influence other authors in the field.     

A decade of African Peace and Security Architecture

This article examines how the African Union (AU) has handled Africa's peace and security challenges since 2002, defines what has been successful and what remains aspirational. It does so by examining how the AU has responded, from using sanctions against coups, to deploying peacekeeping missions and mediating in conflicts. An African Peace and Security Architecture (APSA) has developed since 2002, including a Peace and Security Council, an African Standby Force, a Continental Early Warning System and a Panel of the Wise. This sounds impressive, but the operationalization record is patchy: AU‐deployed missions have been fully dependent on external donors; harmonization is a major problem; serious questions remain over AU capacity; and some of the Regional Economic Communities (RECs) are developing at a quicker pace than the AU. Given these circumstances and its internal capacity deficit, the AU will likely struggle to exercise oversight of regional processes, including the development of regional standby force arrangements. APSA is clearly based on a liberal peace model, yet democratic systems, respect for human rights and good governance aren't always in place in African countries, and the self‐interest of elites continues to be a constraint on APSA and its success. Over the last decade the AU has found a voice and, despite some setbacks, it has shown through AMISOM in Somalia that it is capable of conducting a successful peacemaking operation. Its biggest challenge is not making the decision to intervene or deploy forces, but the capacity of most African states to deploy effectively. APSA's dependence on external partners needs to diminish over the next decade if better African solutions are to be found to peace and security challenges in the continent. Yet, the internationalized nature of crises such as the one in Mali in 2012–13 requires international partnerships. Not all of Africa's security problems can be solved by Africa alone, but APSA does provide a vision framework for African and external partnership.     

COMPLEMENTARY COMPOSITIONAL ANALYSIS OF FORMATIVE PERIOD CERAMICS FROM THE TEOTIHUACAN VALLEY

During the Classic Period, Teotihuacan was an economic centre of central Mexico, but little is known about the development of this system. This paper presents a pilot study in multi‐method analysis of Formative Period (1500/1400 bc –ad 150) ceramics from the Teotihuacan Valley. Pottery was characterized by instrumental neutron activation analysis, laser ablation inductively coupled plasma mass spectrometry, thermal ionization mass spectrometry and petrography. It appears that most pottery was made from local raw materials that differ from later Postclassic materials. Some inter‐village interaction is suggested by stylistic choices, and one settlement had a group of ceramics made from unequivocally distinct raw materials. The study demonstrates how complementary methods can be used to draw greater anthropological meaning from compositional differences.     

SHAFT‐HOLE AXES FROM CAPUT ADRIAE MADE FROM AMPHIBOLE‐RICH METABASITES: EVIDENCE OF CONNECTIONS BETWEEN NORTHEASTERN ITALY AND CENTRAL EUROPE DURING THE FIFTH MILLENNIUM BC

Here we show the results of a study concerning a small group of shaft‐hole axes found in northeastern Italy, made from amphibole‐rich metabasites, fine‐grained and free of phenoblasts. The main mineral phases are amphibole, ranging from actinolite to hornblende, and plagioclase (An_10–15 and An_70–77). The amphiboles generally show a needle shape and are often radially arranged. Quartz is present in thin veinlets, while ilmenite is widespread in small patches. The petrographic and geochemical features suggest that the axes originate from the southern thermal aureole of Tanvald granite in northern Bohemia. In accordance with this provenance, the typology of the tools shows similarities with the perforated shoe‐last axes spread across Central Europe during the fifth millennium bc and made from similar raw material. For the first time, these axes give evidence of long‐distance (about 800 km) contacts between northeastern Italy and Central Europe during the Neolithic.     

Quaternary Organic Deposit from Newton Creek Valley,Western Tasmania

Pollen and macrofossils from an organic deposit probably 44 ka BP in age record subalpine heath with abundant local Athrotaxis cupressoides. This was succeeded by subalpine heath that included Casuarina, Phyllocladus and Eucalyptus. The pollen/vegetation assemblages are comparable with present subalpine vegetation located between 850–1050 m, though the site is at 550 m and potentially below the limit of temperate rainforest (620 m). It is inferred that the vegetation altered from upper to lower subalpine heath and that the climate became warmer and wetter. The mean temperature is estimated to have been at least 3.2°C to 1.7°C colder than today. The trend of vegetation and climate change compares closely with Late Glacial changes but does not compare with changes recorded from sites of Middle Last Glacial age in the West Coast Ranges. A radiocarbon date of 34 ka BP and a trend towards warming suggests that the deposit may represent the onset of an interstadial during the Early Last Glacial Stage.
