Tanzania's endangered heritage: A call for a protection program

There is no doubt that heritage resource loss in Tanzania is proceeding at an alarming rate. Natural and human agencies, adverse storage infrastructures and techniques, and lack of trained conservators and curators and of a proper protection program are the major threats that endanger the heritage resources of Tanzania. As our natural and cultural environments bring irreparable damage to the resources that document our human history, we need to preserve and protect them before they vanish. A preservation and protection program for Tanzania should include public education, the establishment of heritage preservation laws, more progress in the inventory and protection of in situ heritage resources, research into preservation and conservation methods, training of staff, and improvements in the curation of collected heritage resources and records. Preservation and protection of heritage resources are collaborative exercises. The scientific and world community need to support and engage in this proposed program both technically and financially, if the preservation and protection of heritage resources in Tanzania are to succeed.

Résumé Il ne fait pas de doute que la perte des ressources du patrimoine historique se poursuit à un rythme alarmant en Tanzanie. Les agents naturels et humains, des techniques et des locaux de conservation inadaptés, el manque de conservateurs bien formés et d'un programme de sauvegarde adéquat sont les principales menaces qui pèsent sur les biens historiques et culturels en Tanzanie. Comme notre environnement naturel et culturel provoque des dommages irréparables aux sources historiques, nous devons les préserver et les protéger avant qu'elles ne disparaissent. Un programme de préservation et de protection pour la Tanzanie devrait inclure l'éducation du public, l'adoption de lois relatives à la sauvegarde du patrimoine, de nouveaux progrès dans l'inventaire et la protection in situdes vestiges, des recherches sur les méthodes de préservation et de conservation, la formation des responsables et l'amélioration des conditions de conservation et de récolte des objets et de la documentation. La préservation et la protection des vestiges du patrimoine impliquent une large collaboration. Pour arriver à la préservation et à la protection des ressources du patrimoine tanzanien, el faut que la communauté scientifique et mondiale s'implique et soutienne ce projet à la fois techniquement et financièrement.

     

Characterization and textural analysis of Middle Bronze Age Transdanubian inlaid wares of the Encrusted Pottery Culture,Hungary: a preliminary study

Inlaid ceramics belonging to the Encrusted Pottery Culture and dated to the Middle Bronze Age (2000–1500 BC) are highly distinctive vessels with complex decorative motifs found in large numbers in the Transdanubia region of Hungary. Despite this considerable corpus of material there has been little systematic investigation of the composition of the inlays. Micro-analysis of Transdanubian inlaid wares by X-ray diffraction (XRD), micro-Fourier transform infrared microscopy (FT-IR), and scanning electron microscopy (SEM) provides new compositional, structural and textural information on the inlays. In contrast to common statements in the literature regarding the materials used to make inlays, these new data show that the majority of inlays are composed of hydroxyapatite (bone) that was previously ashed, although some of the inlays are composed of calcium carbonate. Additional compositional and textural variation in the bone inlays suggests that bone material from different skeletal elements and/or of different age may have been used, and that contrasting recipes for inlay preparation were employed during fabrication. These results suggest that the production of inlaid vessels of the Encrusted Pottery Culture was more complex than has hitherto been thought.     

Historic landscape management: a validation of quantitative soil thin-section analyses

The archaeological interpretation of past land management practices can be greatly enhanced through examination of soil thin sections. Features relating to manuring practice are among those key to interpreting agricultural practices. The sources and the processes leading to the distribution of these manure materials may further improve knowledge of the past landscape utilisation. The use of quantitative analyses to examine soil thin sections opens the possibility of considering these relationships between manured areas in greater detail and to extract more subtle spatial and temporal changes in past management. In this study the validation of this methodology has been tested with quantitative image analysis methods used to examine manure inputs to a well-documented historical landscape of Papa Stour, Shetland, where intensive manuring has been practised until the 1960s. By using both historic and ethnographic evidence to validate the image analysis protocol, differences in spatial and temporal distribution are examined for the practices of manuring with both fuel residues and with turf. The validation of the hypotheses expected from ethnographic and historical data that quantitative soils-based evidence allows the definition of variations in manuring strategies and provides a more secure basis from which to interpret manuring management strategies in archaeological landscapes.     

Identifying sword marks on bone: criteria for distinguishing between cut marks made by different classes of bladed weapons

Swords have been one of the major weapons used in violent conflicts for much of human history. Certain archaeological situations, especially those dealing with the recovery and analysis of battle casualties, may raise questions about what type(s) of bladed weapon was used in a particular conflict (e.g., the battle of Kamakura, Japan, AD 1333; the battle of Wisby, Sweden, AD 1361; the battle of Towton, England, AD 1461). Little work has been done, however, on developing criteria to differentiate sword cut marks from other types of cut marks, or to distinguish between marks created by different sword types. To develop such criteria, bovine tibiae (n = 7) were struck using six different types of bladed weapon and the resulting marks (n = 92) were analyzed. Eight traits describing the morphology of the cut mark – such as shape, the presence and unilateral/bilateral state of flaking and feathering, the presence of bone shards, associated breaks, etc. – are defined and related to blade type used. Sword marks were found to be easily distinguishable from knife marks. The variation in marks made by different sword types is significantly correlated with differences in blade weight (p < 0.0001), grip (p < 0.0113), and sharpness (p ≤ 0.0179). The criteria and analyses developed and implemented in this study will be of use to researchers in forensics and osteoarchaeology who want to infer bladed weapon type from marks on bones.     

Social reform through parks: the American Civic Association's program for a better America

The American Civic Association, an urban, elite organization based in Harrisburg, Pennsylvania, and Washington DC, provided a major impetus to the creation of the National Park Service in 1916. The association had actively involved itself with national parks for nearly a decade before 1916 despite the fact that most members lived far from the national parks in the West. This article argues that the concern of the American Civic Association for national parks sprang from its conviction that parks comprised vehicles for reforming society. They dismissed the differences in scale between national and urban parks as irrelevant to the ability of parks to affect society. All properly organized parks offered means to improve America. They characterized the reformed society that would follow on the heels of a national park system as healthy, wealthy, equal and patriotic, the same qualities that they attributed to a post-urban park society. The significance of the national parks for the American Civic Association, therefore, came from the presumed ability of these parks, like all parks, to foster a better America.     

Thousand years of vegetation history revealed by pollen in a sandy soil,central Netherlands

Abstract

Within the scope of an interdisciplinary research project to determine the genesis and age of small clusters of oak trees, three soil sections in and three outside oak clusters in an ancient woodland/heath on the Veluwe, central Netherlands, were sampled for palynological analysis. The sections within the clusters show an undisturbed development from the Medieval period onwards, the sections outside the clusters are missing ca. 15 cm because of sod cutting associated with plaggen soil formation. The rate of downward movement of pollen was established, using known dates from the near surroundings.     

Identifying past agricultural activity through soil phytolith analysis: a case study from the Hawaiian islands

Soil samples from documented archaeological sites and adjacent fields were analyzed for phytolith assemblage in an effort to identify and reconstruct prehistoric and early historic agricultural systems on the Island of Hawaii. The removal of indigenous tree and shrub vegetation, subsequent agricultural activity, and eventual abandonment of the fields can be identified in the areas tested. The applicability of phytolith analysis to archaeological problems is advanced and areas of strength and weakness identified.     

Western Australia's Royalties for Regions program: a policy response to growth,regional neglect,and perceived disempowerment

Under the right conditions, compounding socio‐political and economic change can dramatically alter government policy. From 2000, Western Australia, a resource‐rich jurisdiction, experienced significant change owing to a once‐in‐a‐generation resources boom, which forced a break with earlier development approaches. In 2008, regional interventionism returned to the State via the State Government's Royalties for Regions program. Departing from the neo‐liberal tradition, the program allocated 25 per cent of the State's royalty income to non‐metropolitan regions, over and above existing regional allocations, and its success remains disputed. While it is easy to question the program retrospectively, the socio‐economic and political circumstances from 2000 to 2008 reveal a “perfect storm” of conditions enabling the transition from neo‐liberalism to interventionism in regional development. This paper sets out to understand the multi‐faceted conditions that enabled the dramatic paradigm shift embodied by the program. To this end, it examines the State's rural–urban settlement dichotomy, its staples economy, and the policy context leading up to the program. Following that, the paper proposes a causal framework mapping out the factors driving and rationalising the program. These factors are then examined in detail and include perceived rural voter disenchantment, ineffectual regional development policy, the State's mining boom, inadequate regional development funding, the contrasting fortunes of two regions (illustrative of the impact of growth, and the lack thereof), and the political manoeuvring during the 2008 election. Finally, the paper concludes by considering how the conversion of these conditions resulted in the State's most significant regional policy redirection in decades.     

Evaluating soil resilience in long-term cultivation: a study of pre-Columbian terraces from the Paca Valley, Peru

This study evaluated the soil properties of pre-Hispanic stone-walled terraces by comparing soil quality along terraced catenas in the Paca Valley, a tributary of the Mantaro Valley, Peru. Micromorphological and bulk analyses of terrace soils revealed that despite terracing soil horizonation largely followed the catena. Upland terraced fields had deeper A-horizons with higher biotic activity than uncultivated controls, but less fine material and greater carbonate accumulation. Midslope fields were highly variable in depth and soil properties reflecting considerable substrate and anthropogenic variations in this growing zone. Silts and clay accumulated in valley bottom terraces where pedofeatures indicate an ongoing downhill movement of fine material. The distribution of soil separates down Paca hillsides demonstrates that terraces help moderate, rather than control, the erosion of key soil fractions required for long-term agricultural productivity. This study illustrates how the loss of fine material is partly mitigated by soil consolidation in dense topsoil peds, microaggregates and saprolite. These aggregates are retained by terraces and contribute to deep soil profiles. Nevertheless, many fields show signs of degradation, especially from insufficient organic matter amendment. In addition to farming itself, buried soils and associated artefacts in valley bottom fields indicate mass soil movement, a likely result of disruption caused by Inca road and terrace construction. The poor soil quality of many upland terraces also confirms that stone-walled terraces were constructed on mediocre substrates for farming, indicating a high labour investment for marginal agricultural returns in these areas. Overall, Paca Valley terraces improve topsoil retention and promote deep soil profiles. However, these fields present quite varied growing substrates. It is also apparent that over the last millennium, soil depletion from cultivation has compromised soil quality through loss of fine material and organic matter. Shifts in farming practice away from pre-Hispanic practices such as long-fallow and middening appear to exacerbate this trend.     

The risk of harm to archaeological artefacts in soil from dynamic subsurface pressures generated by agricultural operations: experimental studies

An investigation was made of the fracture risk to buried ceramic pots and bones from the subsurface pressures generated by agricultural operations. A method for generating subsurface pressures at 0.25 m depth in a soil bin was developed and used to explore fracture failure of modern replicates of ceramic pots corresponding to different archaeological periods and aged medieval human bone. Application of conductive traces to the objects’ surfaces allowed detection of fracturing in real‐time without excavation. Predictive models relating fracture of objects to subsurface pressure application were developed by relating the probability of fracture to observed survival statistics at increasing subsurface pressures. Subsurface pressures of above 100 kPa were sufficient to fracture the more fragile pots at a probability level of 90%. The lowest subsurface pressure causing bone fracture was 280 kPa; however, no relationship was observed between subsurface pressure and bone fracture, probably due to variation in bone material. The subsurface pressures generated and applied are within the range reported from field measurements during typical agricultural operations. They indicate that measures to control the generation of subsurface pressures would be necessary to mitigate risk of harm from agriculture to buried archaeology; for example, via low‐pressure tyres, tracks and appropriate tillage.     

Rapid,in-stride soil phosphate measurement in archaeological survey: a new method tested in Loudoun County,Virginia

We report the development and field test of a modified method for soil phosphate analysis for survey archaeology. Consideration of relative, rather than absolute, phosphate levels permits the abbreviation of standard extraction techniques, while two-color spectral monitoring provides reliable values without the need for the typical 40–60 min development period. Using this technique, a soil sample may be fully analyzed for phosphate in as little as 6 min. The technique was used in the field simultaneously with a standard woodland shovel-testing survey in an effort to locate a now lost historic farmstead in northwest Loudoun County, Virginia.     

Neolithic occupation and mid-Holocene soil formation at Encosta de Sant'Ana (Lisbon,Portugal): a geoarchaeological approach

Excavations at the archaeological site of Encosta de Sant'Ana (Lisbon, Portugal) uncovered a mid-Holocene buried alluvial soil associated with early Neolithic occupation layers. Routine laboratory analyses and micromorphological observations were undertaken on the soil material. Humic acids from its Ab horizon, as well as Neolithic ecofacts, were radiocarbon dated. The dates obtained indicate that soil was formed between c. 8.0 and 6.0 cal ka BP and that the pedological evidence fits the record of the North Atlantic Holocene IRD events (“Bond events”) and the so-called “Holocene climate optimum”. The geoarchaeological record reveals that Neolithic inhabitants settled upon a stable surface, still affected by soil formation that was suddenly interrupted by slope wasting, probably in correspondence to Bond event 4, at c. 6.0 cal ka BP.     

Determination of the influence of soil parameters and sample density on ground-penetrating radar: a case study of a Roman picket in Lower Bavaria

Ground-penetrating radar (GPR) surveys are very much influenced by the site-specific physical properties, soil parameters and the sample density of the radar pulses. According to the electromagnetic theory, the transmission and reflection of electromagnetic waves is dominated by the conductivity, dielectric permittivity and the soil moisture. Therefore, it is advisable to measure these parameters in advance of a GPR survey. Commonly, this is not possible directly with the standard common-offset GPR arrays. To overcome this problem, we adapted and applied a direct method called time-domain reflectometry to a selected case study of the Roman picket Hienheim at the Raetischer Limes in Lower Bavaria. Furthermore, we present some important results relating to the profile spacing and orientation of GPR surveys and the site-specific soil parameters. The location and the identification of the archaeological features were successful by all geophysical methods. However, the application of all these geophysical methods like magnetometry, resistivity and GPR in addition with aerial photography and Airborne Laserscanning exemplifies the advantages of an integrated survey to achieve a comprehensive result of an archaeological site. The Roman picket of Hienheim shows up differently in all results, as each one traces the archaeological remains according to a specific physical parameter. Resistivity and radar are best to resolve buried stone structures like the walls of the picket or stone-filled ditches. In contrary, magnetometry benefits of the magnetic contrast between the limestone walls and the surrounding soil.     

Research-based learning for undergraduate students in soil and water sciences: a case study of hydropedology in an arid-zone environment

This article reports the efficacy of a research-based learning (RBL) exercise on hydropedology of arid zones, with guided and open research projects (OPR) carried out by teams of undergraduate students in Oman. A range of activities and assessments was used to support student learning during the three-month course. Assessment included monitoring of field trip and lab activities, attendance recording, scrutiny by a panel of written reports and open oral presentations. Students’ feedback through teaching evaluation is compared with other courses in the Department-College, illustrating high level of students’ satisfaction. OPR best fit the scaffold of RBL.     

Resurrection: a tale of two anthems sung by Serbs

ABSTRACT. This paper presents a comparative study of two key contenders for Serbian anthem‐hood, the royalist song ‘God of Justice’ and the pan‐Slavic hymn, ‘Hey Slavs’. Drawing on the theorising of nation and representation, as developed by Benedict Anderson, Michael Billig and others, the purpose of the study is to compare the self‐images these songs present to those they enjoin in unison, and to consider the role of those images and the identities they suggest in national/ist ideologies. Neither of the songs discussed in this paper was originally intended to be a national song. Both are in this sense ‘accidental anthems’. The paper will discuss the history of the accidents which have at various times given, and deprived, these songs of anthem status, in Serbia. ‘God of Justice’, originally a song in a patriotic stage play of the 1870s (commissioned to legitimise a young prince's accession to the Serbian throne), was the national song and later the official national anthem of the Principality of (later Kingdom of) Serbia from 1872 to 1919 and then, in a changed form, part of the national anthem of the Kingdom of Yugoslavia from 1919 till 1941. It was resurrected in 2006, in a changed – republican – form to become the national anthem of the Republic of Serbia. The pan‐Slavic ‘Hey Slavs’, written in 1842, emerged, a century later, first as a national song of the Communist‐led resistance movement in Yugoslavia in 1942 and then became an unofficial national anthem of the Communist‐ruled Yugoslav federation; it survived the violent disintegration of that federation in 1991 to serve (once again unofficially) as an anthem of the rump Yugoslavia from 1992 to 2006. Why have these particular songs been chosen for the purpose of representing the Serbian nation to itself and to the world? How has each succeeded and failed in that task? The essay concludes with some speculation on these questions.     

Forcing atmospheric oscillations by long-period seismic oscillations: a case study

Using synchronous measurements made by microbarograph and a seismograph with a vertical pendulum, the sign of the vertical direction of the wave energy flux in the atmosphere at the ground has been derived for oscillations in the ∼0.5–4 h period range and which occur simultaneously in the Earth and atmosphere. The seismic oscillations shown could generate atmospheric oscillations by the ‘piston’ mechanism. A change of sign of the flux direction is also observed.
