In April 1989, ninety-six men, women and children, supporters of Liverpool Football Club, died in a severe crush at an FA Cup semi-final at Hillsborough Stadium, Sheffield. Hundreds were injured and thousands traumatised. Within hours, the causes and circumstances of the disaster were contested. While a judicial inquiry found serious institutional failures in the policing and management of the capacity crowd, no criminal prosecutions resulted, and the inquests returned ‘accidental death’ verdicts. Immediately, the authorities claimed that drunken, violent fans had caused the fatal crush. Denied legitimacy, survivors’ accounts revealed a different story criticising the parlous state of the stadium, inadequate stewarding, negligent policing, failures in the emergency response and flawed processes of inquiry and investigation. Reflecting on two decades of research and contemporaneous interviews with bereaved families and survivors, this article contrasts the official discourse with those alternative accounts – the ‘view from below’. It demonstrates the influence of powerful institutional interests on the inquiries and investigations. It maps the breakthrough to full documentary disclosure following the appointment of the Hillsborough Independent Panel, its research and key findings published in September 2012. The campaigns by families and survivors were vindicated and the fans, including those who died, were exonerated. The process is discussed as an alternative method for liberating truth, securing acknowledgement and pursuing justice.

Purpose This chapter explores the ideas of Alasdair MacIntyre and Vaclav Havel and what these two thinkers can contribute to green political theory. Design/methodology/approach This chapter includes examination of some of the key works of Havel and MacIntyre and analysis of these works from the point of view of green political theory. Findings The section ‘Havel and the Imperative to “Live in Truth”: Dissent and Green Politics’ explores Havel’s thought with a particular emphasis on his ethicised notion of political action and critique (‘living in truth’) and his focus on the centrality of dissent (both intellectually and in practice) as central to political critique and action. The section ‘MacIntyre as a Green Thinker: Vulnerability in Political and Moral Theory’ offers an overview of MacIntyre interpreted as a putative green thinker, with a particular emphasis on his ideas of dependence and vulnerability. The Conclusion attempts to draw some common themes together from both thinkers in terms of what they have to offer contemporary green political thought. Research limitations/implications What is presented here is introductory, ground clearing and therefore necessarily suggestive (as well as under-developed). That is, it is the start of a new area of exploration rather than an analysis based on any exhaustive and comprehensive knowledge of both thinkers. Practical implications This chapter offers some initial lines of exploration for scholars interested in the overlap between green thinking and the work of Havel and MacIntyre. Originality/value This is the first exploration of the connections between the works of Havel and MacIntyre and green political theory.

We present the probable ground-based detection of the secondary eclipse of the transiting exoplanet WASP-19b. The observations were made in the Sloan z'-band using the ULTRACAM triple-beam CCD camera mounted on the NTT. The measurement shows a 1±0.2mmag eclipse depth, consistent with a dayside temperature of 2900K, matching previous predictions based on H- and K-band measurements. However, since this is based on a single observation, the eclipse depth - at the moment - is not particularly well constrained, and would benefit from additional observations at similar wavelengths. Our technique for the data reduction and analysis is described, along with our approach to dealing with systematic errors associated with ground-based secondary eclipse observations.

Organisms respond to cyclical environmental conditions by entraining their endogenous biological rhythms. Such physiological responses are expected to be substantial for species inhabiting arid environments which incur large variations in daily and seasonal ambient temperature (T). We measured core body temperature (T) daily rhythms of Cape ground squirrels Xerus inauris inhabiting an area of Kalahari grassland for six months from the Austral winter through to the summer. Squirrels inhabited two different areas: an exposed flood plain and a nearby wooded, shady area, and occurred in different social group sizes, defined by the number of individuals that shared a sleeping burrow. Of a suite of environmental variables measured, maximal daily T provided the greatest explanatory power for mean T whereas sunrise had greatest power for T acrophase. There were significant changes in mean T and T acrophase over time with mean T increasing and T acrophase becoming earlier as the season progressed. Squirrels also emerged from their burrows earlier and returned to them later over the measurement period. Greater increases in T, sometimes in excess of 5°C, were noted during the first hour post emergence, after which T remained relatively constant. This is consistent with observations that squirrels entered their burrows during the day to 'offload' heat. In addition, greater T amplitude values were noted in individuals inhabiting the flood plain compared with the woodland suggesting that squirrels dealt with increased environmental variability by attempting to reduce their T-T gradient. Finally, there were significant effects of age and group size on T with a lower and less variable T in younger individuals and those from larger group sizes. These data indicate that Cape ground squirrels have a labile T which is sensitive to a number of abiotic and biotic factors and which enables them to be active in a harsh and variable environment.

Soil conditioning consists of mixing and remolding the natural material during the mechanical excavation of tunnels, generally at low depth, with additives, in order to obtain suitable properties of plasticity and consistency for the excavated material, so becoming able to apply a counterpressure against natural earth pressure and groundwater flow towards the excavation chamber. The assessment and the control of the soil parameters and of machine performance are fundamental for a regular and safe excavation, also with regards to surface stability. This paper mainly focus on testing approach aimed to the proper soil conditioning with EPB shields, whose results have been validated at real scale. The influence of the water content and the amount of conditioning foam has been studied by the Authors. A proper definition of conditioning parameters can allow to extend the application field of Earth Pressure Balance (EPB) tunnel machines to various grain soil distribution, even in weak rock formations (e.g. siltstone or flysch). Importance of conditioning is reflected also on the possibility of a proper spoil disposal or better for its reuse.

This book investigates why some societies defer the solution of transitional justice issues, such as the disappeared/missing, even after successful democratic consolidation. It also explains why the same societies finally decide to deal with these human rights issues. In short, it considers the interesting and understudied phenomenon of post-transitional justice. The prolonged silences in Spain, Cyprus and Greece contradict the experience of other countries -- such as South Africa, Bosnia, and Guatemala -- where truth recovery for disappeared/missing persons was a central element of the transition to peace and democracy. Despite democratization, the exhumation of mass graves containing the victims from the violence in Cyprus (1963-1974) and the Spanish civil war (1936-1939) was delayed until the early 2000s, when both countries suddenly decided to revisit the past. Cyprus and Spain are not alone: this is an increasing trend among countries trying to come to terms with past violence. Interestingly, despite similar background conditions, Greece is resisting the trend, challenging both theory and regional experience. Truth Recovery and Transitional Justice considers three interrelated issues. First, what factors can explain prolonged silence on the issue of missing persons in some transitional settings? Second, which processes can address the occasional yet puzzling transformation of victims’ groups from opponents of truth recovery to vocal pro-reconciliation pressure groups? Third, under which conditions is it better to tie victims’ rights to an overall political settlement? The book looks at Spain and Cyprus to show how they have attempted to bring closure to deep trauma by exhuming and identifying their missing, albeit under considerably different conditions. It then probes the generalizability of the conclusions on Spain and Cyprus by looking at the Greek experience; oddly, despite similar background conditions, Greece remains resistant to post-transitional justice norms. Interestingly, each case study takes a different approach to transitional justice.

The fate of missing persons is a central issue in post-conflict societies facing truth recovery and human rights dilemmas. Despite widespread public sympathy towards relatives, societies emerging from conflict often defer the recovery of missing for decades. More paradoxically, in post-1974 Cyprus, the official authorities delayed unilateral exhumations of victims buried within cemeteries in their own jurisdiction. Analysis of official post-1974 discourse reveals a Greek-Cypriot consensus to emphasise the issue as one of Turkish aggression, thus downplaying in-group responsibilities and the legacy of intra-communal violence. We compare the experience of Cyprus with other post-conflict societies such as Spain, Northern Ireland, and Mozambique and explore the linkages between institutions and beliefs about transitional justice. We argue that elite consensus initiates and facilitates the transition to democracy but often leads to the institutionalization of groups opposing truth recovery even for in-group members.

Contrary to the experience of other countries with memories of clandestine violence and “missing persons”, where the mobilisation of the (civil) society towards “truth recovery” was immediate and pivotal, the societies of Cyprus and Spain remained silent for a remarkably long period of time. This article aspires to explain the reasons why both Cypriot communities and the Spanish society did not manage, until recently, to comprehensively address—not to mention resolve—the problem of “missing persons”. The recent emergence of the “politics of exhumations” in these two countries, which highlight issues related to truth recovery and collective memory, renders the attempt to respond to the question of why these processes are taking place only today even more stimulating
