The Middle Neolithic of Morocco’s North-Western Atlantic Strip: New Evidence from the El-Khil Caves (Tangier)

The period comprising the end of the Early Neolithic and the Middle Neolithic, dated broadly within the fifth millennium cal BC, corresponds to an interval that remains largely unknown in the extreme north-western tip of Africa. This situation contrasts with that of the Early Neolithic, a period characterised by the earliest evidence of the diffusion of a productive economy, cultivated plants and domestic animals. The paucity of data for these later phases can be explained in part by the lack of secure contexts and sequences based on radiocarbon datings of short-lived samples. The current study presents the results of the excavations of El-Khil Caves B and C that yield materials allowing re-evaluation of the chronology of a type of ceramic known as Ashakar ware. The study also identifies two traditions in the northern Moroccan Middle Neolithic. The first is heir to the so-called Impressa Mediterranean ware and rooted in the Cardial Neolithic, while the second is characterised by roulette cord impressions, red slip and tunnel lugs and probably rooted in the region of the Sahara, and has no technological precedents in the study area.     

TO CATCH THE ECHO: RETHINKING ACTS OF WITNESSING TO THE SHOAH

In light of recent revelations about global ignorance and disbelief regarding the Holocaust, first‐hand testimonies acquire fresh significance. Two disparate books frame this discussion of how writings by survivors serve to deepen our understanding of the Shoah. Otto Dov Kulka's memoir, Landscapes of the Metropolis of Death, is a carefully crafted account by a professional historian who survived as a child in Auschwitz. Thomas Trezise's work, Witnessing Witnessing, is an analytical inquiry into the literary and epistemic issues that frame different genres of testimony ranging from video to poetry. Kulka's slender account is situated in the context of other works by survivors, including Saul Friedländer's When Memory Comes, Charlotte Delbo's Auschwitz and After, and a more recent work by Joseph Polak, After the Holocaust the Bells Still Ring. The emphasis in this discussion is upon the challenges that survivors face in articulating horror, especially to readers in the twenty‐first century. Trezise's more voluminous work is based upon the literary and philosophical theories of Adorno, Levinas, and Freud, among others. The question raised in this essay focuses upon which of these narrative strategies might work better to convey the complex meanings of the Shoah after the generation of survivors has departed from the historical scene. In the end, the halting words of those who went through the death camps is all we have to counter the ignorance and disbelief spreading around the world. Kulka's book, combining memories, dreams, and art works, fosters an imaginative encounter with inconceivable historical realities. Trezise's theoretical engagement with indexicality and with the phatic function of language helps us to understand the impact of testimonies within the scholarly literature. It does not, however, point a clear path toward conveying the importance of the Holocaust to the public at large. For this purpose, we need books such as Kulka's that enable the generation after the Holocaust to listen to silences embedded in survivor narratives. These silences must be carried forward in time, along with the ethical mandate not to forget the atrocities of the Shoah. If we can embrace this mission, we may be able to diminish the reign of hate running amuck today.     

Chemical and mineralogical characterization of Aguada Portezuelo pottery from Catamarca,north-western Argentina: PIXE,XRD and SEM-EDS studies applied to surface pre- and post-firing paints,slips and pastes

Particle-induced X-ray emission (PIXE), X-ray diffraction (XRD), electron microprobe analysis (EDS) and scanning electron microscopy (SEM) analytical techniques were used to characterize surface paints in pre- and post-fired Aguada Portezuelo decorated pottery. Surface paintings in black, white, red, brown, burgundy and ochre were analysed. Major, minor and trace elements were detected by PIXE, whereas XRD and SEM-EDS gave information on the main mineral phases and the characteristic morphology for each analysed pigment. The results obtained indicate that the main colour groups can be easily discriminated by PIXE, and they are characterized by only one pigment for each colour: hematite (red) and manganese mineral oxides (black), respectively, whereas white pigments are characterized by calcite, ghelenite and gypsum.     

Does specific demographic education change young people’s opinions about reproduction? The case of Serbia

Population education is one of the strategic measures to encourage giving birth in low-fertility Serbia. The expected result is that such education may have an effect on reproductive intentions and overall people behavior. This study explores the thoughts about reproduction of three different student groups from the University of Belgrade, whereas their specific knowledge about demography ranges from basic to very good. The intention was to clarify whether awareness and knowledge about demographic problems change attitudes on reproduction of future highly educated people. The study was performed via a survey that was conducted among: Demography students, who have studied demographic phenomena for at least 3 years, students who have taken only one course in demography during their studies and students who have not acquainted themselves with demographics throughout their studies. It is based on the students’ views of ideal, desired and expected family size, on an evaluation of factors that affect reproduction, on identifying other beliefs relevant for future reproduction, as well as on a discussion with Demography students. Demographic education did not show to be an essential factor of differentiating reproductive norms of students. “Collective rationality” and a reflection of the economic crisis on reproductive intentions are dominant student responses.     

Engaging Local Knowledge in Biodiversity Research: Experiences from Large Inter- and Transdisciplinary Projects

Abstract

The management of biodiversity represents a research topic that needs to involve not only several (sub-) disciplines from the natural sciences but, in particular, also the social sciences and humanities. Furthermore, over the last couple of years, the need for the integration of other kinds of knowledge (experience based or indigenous knowledge) is increasingly acknowledged. For instance, the incorporation of such knowledge is indispensable for place-based approaches to sustainable land management, which require that the specific ecological and social context is addressed. However, desirable as it may be, such an engagement of the holders of tacit knowledge is not easy to achieve. It demands reconciling well-established scientific procedural standards with the implicit or explicit criteria of relevance that apply in civil society — a process that typically causes severe tensions and comes up against both habitual as well as institutional constraints. The difficulty of managing such tensions is amplified particularly in large integrated projects and represents a major challenge to project management. At the Helmholtz Centre for Environmental Research — UFZ, several integrated research projects have been conducted over the past years in which experience has been gained with these specific challenges. This paper presents some of the lessons learned from large integrated projects, with an emphasis on project design and management structure. At the centre of the present contribution are experiences gained in the coordination and management of LEGATO (LEGATO stands for Land-use intensity and Ecological EnGineering — Assessment Tools for risks and Opportunities in irrigated rice based production systems, see www.legato-project.net), an ongoing, large-scale, inter- and transdisciplinary research project dealing with the management of irrigated rice landscapes in Southeast Asia. In this project, local expertise on traditional production systems is absolutely crucial but needs to be integrated with natural and social science research to identify future-proof land management systems.     

Trace-element evidence for foreigners at a Maya port in Northern Yucatan

The present paper explores the potentials of trace elements in human dental enamel to indicate mobility and to detect the presence of individuals who had migrated into a community after childhood. Three Pre-Hispanic samples of infants from the Yucatán peninsula were chosen, one from the northern coast (Xcambó), one from the coast of the Gulf of Mexico (Campeche) and the last one from the tropical inland rain forest (Calakmul). Infants’ first permanent molars are the term of reference because infants were very likely born in the same place where they died and therefore are supposed to represent the local geo-chemical environment. Their chemical signature was then compared to the one of the adults from the site of Xcambó. The elemental composition was recorded by means of laser ablation-time of flight-ICP-MS. Sr and Ba (and secondly Mg and I) discriminate well the three infant samples. All the Early Classic adults from Xcambó fall within the range of variation of the site’s infants, while 25% of the Late Classic adults fall outside the range in agreement with archaeological, bioarcheological, and isotopic evidence. LA-ICP-Ms analyses of trace elements in archaeological samples can be an important analytical tool to detect foreigners in local populations. The selection of infants as reference values helps reduce the limits faced by trace element analyses in past human populations studies.     

Deletion/Substitution/Addition (DSA) model selection algorithm applied to the study of archaeological settlement patterning

This paper introduces GIS-based statistical methods for the study of settlement patterning in an archaeological context. The main aspect is an improvement over suboptimal stepwise statistical model selection procedures, with the introduction of a Deletion/Substitution/Addition (DSA) algorithm, a systematic model selection algorithm that provides an optimal model choice. The paper also introduces the combined use of Receiving Operator Characteristic (ROC) curves, and variable ranking as key tools aimed at an understanding of settlement patterning causation. An illustrative case study is provided whereby both a purely environmental and a mixed environmental/historical model (based on settlement hierarchy considerations) are investigated.     

‘Russian merchant’ legacies in post-Soviet trade with China: Moral economy,economic success and business innovation in Yiwu

ABSTRACT

This article focuses on Russian traders operating in China, particularly in Yiwu, the major commercial hub for the ‘small commodity’ trade, and explores the idea of the ‘Russian merchant’ prevalent in Russia today. Rather than examining the new commercial culture from the perspective of global neoliberalism, it deals with Russia’s pre-Soviet merchant estate (soslovie) and its present-day political-ideological evocations. While there is no direct cultural-professional continuity between pre-Soviet and post-Soviet merchants, some similarities have come to the fore and have been encouraged by the state and the Church. This is due to the promotion of a particular moral economy wherein the ‘Russian merchant’ figures as a positive category. Using a case study of a Russian trader in Yiwu, the article illustrates the new ways in which mistrust as well as ‘traditional’ merchant attributes such as patriotism and patriarchal authority, have been harnessed to create a successful Russian transnational business.
