In this article, the authors examine how teachers in four troubled societies – Israel, Cyprus, Northern Ireland and South Africa – understand and implement reconciliation in light of the increasing diversity of these societies. The authors particularly pay attention to a dialogical encounter between reconciliation and inclusion, as they look for ways to contemplate how each might be of mutual benefit in educational theory and practice. In the first part of the article, the authors give an overview of current thinking on reconciliation and its role in education, and suggest that the notion of inclusiveness can enrich it. The context of the research is then provided by looking briefly at the socio-political and educational settings in which the study was conducted, followed by a discussion of the research methodology. The findings from the study are then presented with the main themes identified as arising across the four research locations. These themes concern understandings of reconciliation and inclusion, student diversity, teachers’ challenges, helping students deal with conflict, and teachers’ development. Finally, whilst acknowledging the exploratory nature of these findings, the authors discuss what policy makers, school leaders and teachers might change about policies and practices for reconciliation education in the four settings studied and, by implication, other comparable settings.

The notion of accountability that is propagated in transitional justice often appears limited to demands for the prosecution and imprisonment of those who have been involved in serious human rights violations. Amnesties, widely understood as the absence of punishment for wrongdoing, are in turn considered by many scholars and activists as an example par excellence of the kind of Faustian pacts which are made in the name of political expediency in transitions from conflict. Drawing from a range of interdisciplinary literature, as well as research completed by the authors in a number of societies with a violent past, this paper uses amnesties as a case-study to argue for a more rounded interrogation of the notion of accountability in transitional justice. The paper charts the various forms of intersecting accountability which both shape and delimit amnesties at key ‘moments’ concerning their remit, introduction and operation. The paper concludes that the legalistic view of amnesties as equating to impunity and retribution as accountability is inaccurate and misleading. It argues that a broader perspective of accountability speaks directly to the capacity for amnesties to play a more constructive role in post conflict justice and peacemaking.

The 1980s saw a wave of African films that aimed to represent, on both local and international screens, a sophisticated pre-colonial Africa, thus debunking notions of the continent as primitive. Toward this aim the films inscribed the conventions of oral performance within their visual styles, denying spectator identification with the protagonists and emphasising the presence of the narrator. However, some critics argued that these films exoticised Africa, while their use of oral performance’s distancing effect echoed the ‘scientific’ distance structured by the ethnographic film, in which African societies were represented as ‘the other’. Souleymane Cissé’s Yeelen exemplifies this tension, transposing into cinematic form oral storytelling techniques in the depiction of a power struggle within the covert cult of the komo, a Bambara initiation society unfamiliar to most non-Bambara viewers. This paper demonstrates how the film negotiates this tension via music, which interpellates the international spectator by eliciting a greater identification with the protagonists than that determined at a visual level, while encoding a verisimilitude to rituals that may otherwise be read as the superstitious practices of ‘the other’. In this way, music and image in Yeelen operate as parallel, though often overlapping, discourses, bridging the gap between the film’s culturally specific narrative and formal components, and its international spectators.

Chitons are often referred to as “living fossils” in part because they are proposed as one of the earliest-diverging groups of living molluscs, but also because the gross morphology of the polyplacophoran shell has been conserved for hundreds of millions of years. As such, the analysis of evolution and radiation within polyplacophorans is of considerable interest not only for resolving the shape of pan-molluscan phylogeny but also as model organisms for the study of character evolution. This study presents a new, rigorous cladistic analysis of the morphological characters used in taxonomic descriptions for chitons in the living suborder Lepidopleurina Thiele, 1910 (the earliest-derived living group of chitons). Shell-based characters alone entirely fail to recover any recognized subdivisions within the group, which may raise serious questions about the application of fossil data (from isolated shell valves). New analysis including characters from girdle armature and gill arrangements recovers some genera within the group but also points to the lack of monophyly within the main genus Leptochiton Gray, 1847. Additional characters from molecular data and soft anatomy, used in combination, are clearly needed to resolve questions of chiton relationships. However, the data sets currently available already provide interesting insights into the analytical power of traditional morphology as well as some knowledge about the early evolution and radiation of this group.

Chronic myeloid leukemia (CML) is treated effectively with tyrosine kinase inhibitors (TKIs); however, 2 key problems remain-the insensitivity of CML stem and progenitor cells to TKIs and the emergence of TKI-resistant BCR-ABL mutations. BCR-ABL activity is associated with increased proteasome activity and proteasome inhibitors (PIs) are cytotoxic against CML cell lines. We demonstrate that bortezomib is antiproliferative and induces apoptosis in chronic phase (CP) CD34(+) CML cells at clinically achievable concentrations. We also show that bortezomib targets primitive CML cells, with effects on CD34(+)38(-), long-term culture-initiating (LTC-IC) and nonobese diabetic/severe combined immunodeficient (NOD/SCID) repopulating cells. Bortezomib is not selective for CML cells and induces apoptosis in normal CD34(+)38(-) cells. The effects against CML cells are seen when bortezomib is used alone and in combination with dasatinib. Bortezomib causes proteasome but not BCR-ABL inhibition and is also effective in inhibiting proteasome activity and inducing apoptosis in cell lines expressing BCR-ABL mutations, including T315I. By targeting both TKI-insensitive stem and progenitor cells and TKI-resistant BCR-ABL mutations, we believe that bortezomib offers a potential therapeutic option in CML. Because of known toxicities, including myelosuppression, the likely initial clinical application of bortezomib in CML would be in resistant and advanced disease. (Blood. 2010;115:2241-2250)

This paper aimed to investigate in what ways teachers’ developing understandings of citizenship education in a divided society reflect discourses around national citizenship and controversial issues. Based on thematic analysis of semi-structured interviews with 13 post-primary teachers in Northern Ireland undertaking an in-service programme in citizenship, findings indicate that the controversial nature of past conflict maintains its sensitivity in the educational context though other categories of potential exclusion, such as race and sexuality, compete for space in educational discourse and teaching. Few teachers used controversial issues identified as challenging hegemonic beliefs as an opportunity for role modelling citizenship. However, teachers rarely explored the complex interlinkages between traditional and alternative categories of exclusion. It is argued that this may render teachers’ understandings of citizenship and societal conflict disconnected, which in turn may hinder the potential for citizenship education to address societal divisions and to promote active peace in the long-term.
