Performing 'The Tragedy of Mariam' and Constructing Stage History

Since the rediscovery of Elizabeth Cary’s drama, The Tragedy of Mariam, the play and its author have generated a veritable critical industry. Yet little has been written about performance, a lacuna explained by a reluctance to think about Mariam as a theatrical creation. This article challenges the current consensus by arguing for the play’s theatrical imprint and by analysing two 2013 performances – a site-specific production at Cary’s birthplace, and a production by the Lazarus Theatre Company. Throughout, Mariam is engaged with in terms of casting, costume, lighting, set and movement, issues that have mostly been bypassed in Cary studies.

Constructing random matrices to represent real ecosystems

Models of complex systems with n components typically have order n² parameters because each component can potentially interact with every other. When it is impractical to measure these parameters, one may choose random parameter values and study the emergent statistical properties at the system level. Many influential results in theoretical ecology have been derived from two key assumptions: that species interact with random partners at random intensities and that intraspecific competition is comparable between species. Under these assumptions, community dynamics can be described by a community matrix that is often amenable to mathematical analysis. We combine empirical data with mathematical theory to show that both of these assumptions lead to results that must be interpreted with caution. We examine 21 empirically derived community matrices constructed using three established, independent methods. The empirically derived systems are more stable by orders of magnitude than results from random matrices. This consistent disparity is not explained by existing results on predator-prey interactions. We investigate the key properties of empirical community matrices that distinguish them from random matrices. We show that network topology is less important than the relationship between a species’ trophic position within the food web and its interaction strengths. We identify key features of empirical networks that must be preserved if random matrix models are to capture the features of real ecosystems.

Reva Siegel and the Role of Religion in Constructing the Meaning of ‘Human Dignity

The “religious understanding” of dignity is a topic of considerable complexity and is the subject of extensive scholarship. In this paper, I consider understandings of dignity that are currently under discussion in Roman Catholic circles, not least because Catholic discussions of dignity are often seen as influential in public policy and legal interpretation, directly and indirectly. I shall focus on one relatively neglected issue in legal scholarship: how scholars go about the task of identifying what a particular religion’s understanding of human dignity involves.
To illustrate the methodological problems that such an enterprise raises, I shall take one attempt by a scholar writing in the field of secular legal scholarship to describe Catholic understandings of dignity in the context of abortion and same-sex marriage. The discussion is that of Reva Siegel, an academic lawyer at Yale University; her recent analysis of differing understandings of dignity illustrates some of the issues that arise when the secular scholarly community addresses religious understandings of dignity.
