X‐ray Diffraction and SEM Investigation of Wall Paintings Found in the Roman Temple Complex at Horvat Omrit,Israel

In the present study, the fragments of wall painting found in the Roman Temple Complex at Horvat Omrit were analysed for the first time using the non‐destructive techniques of X‐ray diffraction (XRD) and scanning electron microscopy (ESEM) equipped with energy‐dispersive X‐ray spectroscopy (EDS). The application of these methods enabled unambiguous identifications of the pigments and plaster components of the samples. Quantitative information on mineral composition, crystallite size and elemental composition of each studied paint layer and plaster was collected. Based on the results of the XRD and EDS analyses, the green pigment was identified as celadonite. It was revealed that the Egyptian blue pigment does not contain impurities of tin and lead, and this excludes the use of bronze scrap in its synthesis. Comparison of the mineral composition of the paint layers indicates that a wider palette of colours was obtained by mixing the available mineral pigments. The study of cross‐sections of painted specimens revealed the usage of slaked lime for plastering. The obtained results give a new insight into the wall painting technique employed by ancient artists at Horvat Omrit, in northern Israel.     

Evidence of Metallic Plating on Archaeological Artefacts by Voltammetry of Microparticles

Voltammetry of microparticles using a paraffin‐impregnated graphite electrode (VMP/PIGE) was applied as a very local and non‐invasive analytical technique in order to investigate the presence of remains of metallic plating on two ferrous and one cuprous artefact from the medieval period. The analyses have been performed locally and selectively on regions presenting particular features, such as texture, cohesion and colour differences. The results confirm local differences in chemical composition, leading to conclusions about the presence of metallic plating on these artefacts.     

Image‐Based Modelling from Unmanned Aerial Vehicle (UAV) Photogrammetry: An Effective,Low‐Cost Tool for Archaeological Applications

The recording and 3D modelling of complex archaeological sites is usually associated with high capital and logistical costs, because the data acquisition must be performed by specialists using expensive surveying sensors (i.e., terrestrial laser scanners, robotic total stations and/or ground‐penetrating radar). This paper presents a novel, low‐cost, user‐friendly photogrammetric tool for generating high‐resolution and scaled 3D models of complex sites. The results obtained with unmanned aerial vehicle (UAV) photogrammetry of an archaeological site indicate that this approach is semi‐automatic, inexpensive and effective, and that it guarantees quality.     

Electron Microprobe Analysis of 9th–12th Century Islamic Glass from Córdoba,Spain

Twenty‐six samples from domestic assemblages of 9th–12th century Córdoba were subjected to electron microprobe analysis. The results reveal two main compositional types. The first, encountered in 13 of the samples, seems to result from the combination of plant ashes with high‐impurity sand, and has some contemporary parallels from Syria and Egypt. The second type is a lead–soda–silica glass, encountered in a relatively high proportion of the glasses (11 of the 26 sampled), possibly formed by the addition of lead metal to existing glasses and with very few known parallels. These are among a very small number of results available to date on the chemical composition of glasses from medieval Spain, and the presence of a high proportion of lead–soda–silica glasses is particularly interesting, possibly indicating a technological practice unique to, or originating in, the western Muslim world.     

Reframing Bi‐nationalism in Palestine‐Israel as a Process of Settler Decolonisation

This paper examines some of the emerging critical civil society debates in relation to the one‐state solution being the most appropriate geo‐political arrangement for the articulation of freedom, justice and equality in Palestine‐Israel. This is done with reference to the Israeli Committee Against House Demolitions’ 2012 statement in support of a bi‐national state and the ensuing critiques it attracted from Palestinian supporters of the one‐state position. Drawing on these debates which have largely revolved around Jewish Israeli rights to political self‐determination in Palestine‐Israel, this paper proposes that alternative versions of self‐determination as cultural rights for the established Hebrew‐speaking national community represent a more inclusive form of self‐determination in the eventuality of decolonisation.     

Avoiding Blame—A Comprehensive Framework and the Australian Home Insulation Program Fiasco

It is widely acknowledged in the literature that the study of blame avoidance behavior (BAB) exhibited by public officials is scattered and unconcentrated, and that, for the most part, it neglects both contextual factors and comparative research. These deficits inhibit the production of the kind of generalized findings necessary to better understand potential consequences for the policy process and the workings of political systems. We address these deficits by developing a framework that takes stock of blame avoidance research, clarifies the explanatory potential of contextual factors, and allows for a systematic context‐sensitive cross‐case analysis. For illustrative purposes, the framework is applied to the Home Insulation Program in Australia as a critical case. This case reveals the explanatory potential of contextual factors for the understanding of BAB and the consequences thereof. We conclude by stating the advantages of our framework and explain how it can be used for comparative research.     

Beyond “unwinding”: Constitutional review strategies in consociations

This article contributes to the emerging literature on the role of constitutional courts in consociational democracies. While most works have approached the topic from the perspective of regime dynamics, this analysis focuses on how courts relate to the constitutions they are mandated to enforce. Beyond addressing the empirical question of what choices courts make in their balancing between universal values and stability, this article also investigates how courts do this balancing. Through the analysis of seven cases from two consociations, Bosnia and Herzegovina and Northern Ireland, I argue that courts embrace specific interpretive approaches (proportionality analysis, purposive interpretation, and the political question doctrine) to reconcile the ideas of constitutional supremacy and respect for political agreements. The analysis also demonstrates how—by their nature political—framework agreements establishing consociational settlements become primary reference points for interpreting constitutional documents.     

About time: age,period, and cohort effects on support for Quebec sovereignty

Can age, period and cohort effects help explain support for Quebec sovereignty? Previous work on this question has focused mostly on the effects of age and cohort. We contribute to this debate by adding a period perspective. As such, our study is the first to investigate the impact of age, cohort and period effects in a single study of opinion towards sovereignty in Quebec. We take advantage of an original dataset that includes survey data collected between 1985 and 2012. We use these data to examine the impact of age, birth year and survey year on support for this constitutional option among francophone Quebeckers. Our results are in line with previous work: we show that younger Quebeckers are more likely to support sovereignty, and that some cohorts – namely, respondents born between 1945 and 1959 – are also more likely to favour this option. Perhaps more surprisingly, we find that specific events are comparatively the most important factor to explain fluctuations in Quebeckers' attitudes towards sovereignty.     

Contemporary conflicts,cross‐border military operations,and the declining role of the UN: The case of Turkey and Saudi Arabia

This article examines an emerging trend of cross‐border conflicts between states and non‐state actors. It looks at the narratives fronted by Turkey and Saudi Arabia to justify their operations in northern Syria and Yemen, respectively. The authors argue that the increased inaction and lack of influence by the UN in response to such operations reaffirm states as the core actors in international politics and that national security and interests continue to shape the behavior of actors at the international level. The article concludes that the UN needs to adjust to the new forms of conflicts, actors, and behavior being experienced at the international level if it is to retain its relevance as an anchor of peace and international security.
