External Knowledge,Territorial Inertia and Local Development: An Exploratory Case Study

This study examines the relationship between an entrepreneur's absorptive capacity, the spiral of knowledge and local development. Although a great number of theoretical and empirical studies have pointed out the importance of local networking and informal contacts when spreading knowledge locally, very few of them have provided robust evidence on the role of the entrepreneur's absorptive capacity and external knowledge in local development. This paper tries to explain the reasons why this problem can no longer be ignored and provides a preliminary examination, through an exploratory case study, of the role that the entrepreneur's absorptive capacity and external knowledge play in overcoming territorial inertia and enhancing local development.     

Roman double-layered crucibles from Autun/France: a petrological and geochemical approach

Eighteen double-layered crucible fragments found in an archaeological excavation site of the Lycée militaire (Autun/France), which dates to the Gallo-Roman period, were analysed with a series of classical mineralogical techniques in order to obtain knowledge about the raw materials of the individual layers. This work focuses on the usage of the crucibles as well as technical aspects of their production. The crucible fragments were studied by using petrographical (optical microscopy), elemental (SEM-EDS, EMPA, XRF-WDS) and mineralogical (XRD) techniques.     

A new miniSTR heptaplex system for genetic fingerprinting of ancient DNA from archaeological human bone

The analysis of short tandem repeats (STRs) is a useful tool in various contexts of ancient DNA research. Main applications are the reconstruction of kinship, identification, and authentication. Here we describe a short amplicon autosomal short tandem repeat (miniSTR) heptaplex system for the amplification of D13S317, D21S11, D18S51, TH01, D5S818, FGA and Amelogenin from highly degraded DNA as an inexpensive alternative to commercially available kits. All primers were newly designed and the amplicon length of all systems is less than 200 bp, with the exception of some rare alleles in the FGA and D21S11 systems. To validate the suitability of this system for typing STRs from human specimens with low DNA preservation we systematically tested it on 20 skeletal samples from four archaeological sites representing different burial environments and time spans since death. Finally, to test the sensitivity of the heptaplex system, we analyzed serial dilutions of control DNA and ancient DNA extracts. Using the system we were able to reproducibly obtain full STR profiles, down to a concentration of 0.06 ng DNA. Even with 0.004 ng DNA partial profiles could be amplified. The accumulated power of discrimination for the six selected STR loci is 0.99999984, plus the option of genetic sex determination through Amelogenin. The tests conducted prove that the system presented is efficient and especially suited for cases where STRs have to be typed and sex has to be assessed from human specimens with highly degraded DNA.     

Pre-Roman glass from Mozia (Sicily-Italy): the first archaeometrical data

This study present the results of an archaeometrical investigation performed on a series of opaque pre-Roman glass (vessels and ornaments) dated from the 6th to 4th century BC coming from Sicily. Sixteen core formed vessels, twelve beads, three pendants and one spindle-whorl recovered in the Phoenician-Punic sites of Mozia and Birgi were analysed thought a micro destructive approach. The complete chemical analyses and X-Ray diffraction analyses were performed on small fragments of glass. The aims of this work are: 1) to obtain a chemical characterization of these samples in order to understand the raw materials employed for their production; 2) to obtain information regarding the opacifying phases dispersed in the glass; 3) to make a comparison with the results recently obtained on coeval and similar finds recovered in other cultural context, in particular in Northern Italian Etruscan contexts in order to understand whether they could belong to the same Greek-Eastern production.     

Systems thinking within the scope of education for sustainable development (ESD) – a heuristic competence model as a basis for (science) teacher education

Systems thinking is regarded as a key competence in the field of education for sustainable development (ESD), because it helps students to understand the complexity and dynamics of natural, social and economic systems. In our research group, we developed a competence model that distinguishes four dimensions of systems thinking in ESD. Based on this model, we designed different university courses in biology and geography teacher education and measured their effects on student teachers’ systems thinking and the pedagogical content knowledge for teaching systems thinking with two different tests. Both variables could be effectively promoted depending on the course.     

The last ‘never again’? Srebrenica and the making of a memory imperative

Abstract

Controversy overshadowed preparations for the twentieth anniversary of the Srebrenica genocide, as conflict arose over the adoption of a number of commemorative resolutions: while motions in the Parliament of Bosnia-Herzegovina and the United Nations Security Council were blocked, the US House of Representatives and the European Parliament did adopt declarations. The article outlines how the memory of Srebrenica was de-contextualized from particular interpretations of the past and re-contextualized in favour of universal frames of interpretation. Starting from the interpretations pertaining to Srebrenica from the early 1990s, processes of dealing with the massacre in reports have made it possible to process the lessons learnt from the experience as a narration of progress. In parallel with efforts to establish legal accountability and a local memorial for the massacre’s victims, there has been a series of resolutions commemorating Srebrenica contributing to the formation of a Srebrenica memory regime. That regime mirrors the Holocaust-based global cultural memory imperative, a set of norms and rules of behaviour that was re-actualized and expanded on by Srebrenica as a symbol for the unfulfilled hope of a final ‘never again’. The commemoration of Srebrenica has become a universal ethical imperative that has spread far beyond the actors involved in the 1995 events. The 2015 controversy has to be understood as a (local) act of resistance against the recognition of Srebrenica as genocide and against the selective character of the Srebrenica memory regime.     

Early Maya Ritual Practices and Craft Production: Late Middle Preclassic Ritual Deposits Containing Obsidian Artifacts at Ceibal,Guatemala

This article examines Preclassic Maya ritual practices and craft production by means of a study of ritual deposits containing obsidian artifacts dated mostly to the late Middle Preclassic period (700–350 b.c.) at Ceibal, Guatemala. New ritual practices developed at Ceibal during this period, possibly through political interactions and negotiation involving emerging elites and other diverse community members. Common objects in ritual deposits in the public plaza shifted from greenstone celt caches to other artifacts, including those made of obsidian. The inhabitants of Ceibal engaged in various kinds of craft production, including the manufacture of obsidian prismatic blades. They also conducted public rituals in the Central Plaza, depositing exhausted polyhedral obsidian cores and other artifacts with symbolic significance in caches and as offerings in incipient elite burials and interments of sacrificed individuals. These cores clearly demonstrate the use of a sophisticated blade technology. Like greenstone objects, exhausted polyhedral obsidian cores deposited in cruciform arrangements along the east–west axis of the central E-Group plaza were used as symbols and markers of the center and four cardinal directions within the Maya cosmos. Public rituals were important for creating collective identities and for processes of political negotiation within the community. Emerging elites likely came to play an increasingly important role in public rituals as principal performers and organizers, setting the stage for later public events centered on rulers.
