Monuments, mobility and Medieval perceptions of designed landscapes: The Pleasance, Kenilworth

The Pleasance was a ’virandarium’ or pleasure garden, constructed by Henry V in the grounds of his castle at Kenilworth. Despite its high academic profile and the survival of well-preserved earthwork remains, the Pleasance has never previously been subjected to a programme of detailed archaeological survey and investigation. This article discusses the results of a new analytical earthwork survey undertaken by staff from English Heritage in 2012. It considers the contribution that these new findings make to the wider debate on medieval designed landscapes, with a particular focus on mobility and its role in unlocking the meaning and symbolism embedded in elite landscapes.

Bifurcations and bistability in cavity-assisted photoassociation of Bose-Einstein-condensed molecules

We study the photoassociation of Bose-Einstein condensed atoms into molecules using an optical cavity field. The driven cavity field introduces a dynamical degree of freedom into the photoassociation process, whose role in determining the stationary behavior has not previously been considered. The semiclassical stationary solutions for the atom and molecules as well as the intracavity field are found and their stability and scaling properties are determined in terms of experimentally controllable parameters including driving amplitude of the cavity and the nonlinear interactions between atoms and molecules. For weak cavity driving, we find a bifurcation in the atom and molecule number occurs that signals a transition from a stable steady state to nonlinear Rabi oscillations. For a strongly driven cavity, there exists bistability in the atom and molecule number.

Quantum control of electromagnetically induced transparency dispersion via atomic tunneling in a double-well Bose-Einstein condensate

Electromagnetically induced transparency (EIT) is an important tool for controlling light propagation and nonlinear wave mixing in atomic gases with potential applications ranging from quantum computing to table top tests of general relativity. Here we consider EIT in an atomic Bose-Einstein condensate (BEC) trapped in a double-well potential. A weak probe laser propagates through one of the wells and interacts with atoms in a three-level Lambda configuration. The well through which the probe propagates is dressed by a strong control laser with Rabi frequency Omega(mu), as in standard EIT systems. Tunneling between the wells at the frequency g provides a coherent coupling between identical electronic states in the two wells, which leads to the formation of interwell dressed states. The macroscopic interwell coherence of the BEC wave function results in the formation of two ultranarrow absorption resonances for the probe field that are inside of the ordinary EIT transparency window. We show that these new resonances can be interpreted in terms of the interwell dressed states and the formation of a type of dark state involving the control laser and the interwell tunneling. To either side of these ultranarrow resonances there is normal dispersion with very large slope controlled by g. We discuss prospects for observing these ultranarrow resonances and the corresponding regions of high dispersion experimentally.

Monitoring the safe use of Clozapine : a consensus view from Victoria, Australia

Clozapine is an important antipsychotic agent that has a unique profile of clinical benefits, but that has also been associated with several serious and potentially life-threatening safety concerns. In order to minimise the impact of haematological adverse events, health professionals treating patients with clozapine are currently required to register their patients on a centrally administered data network and to conform to strict protocols. The consensus statement documented in this article extends existing protocols by recommending monitoring of patients treated with clozapine for additional adverse effects during treatment. This consensus statement reflects the current practice at five major public psychiatric hospitals in Victoria, Australia, for the monitoring and management of clozapine-related adverse events, and has been implemented at these sites because of emerging safety concerns associating clozapine with cardiovascular and metabolic adverse effects.

The role of psychotherapy in bipolar disorder

• Adjunctive psychosocial interventions for bipolar disorder target many of the issues that are not addressed by medication alone, including non-adherence, efficacy–effectiveness gap and functionality.

• Psychosocial interventions have been found to reduce relapse, particularly for the depressive pole, and improve functionality.

• Approaches such as psychoeducation, cognitive behaviour therapy, interpersonal and social rhythm therapy, and family therapy have shown benefits as adjunctive treatments.

• Each of the various psychosocial interventions has a unique emphasis, but they share common elements. These include: providing information and education; developing a personal understanding of the illness, such as triggers and early warning signs; having prepared strategies in place for early intervention, should symptoms of illness develop; and promoting a collaborative approach.

• Evidence to date supports the use of adjunctive psychosocial interventions in the management of bipolar disorder.

Children's literature in a global age : transnational and local identities

This essay explores the concept of transnationalism, defi ning this term in relation both to the lived experience of transnational subjects, and to transnational texts for children. It argues that rhetorics of globalization have over-emphasized the impact and signifi cance of global cultural and economic fl ows, although the production of children’s books is to some extent shaped by the internationalization of publishing houses and markets. The concept of transnationalism provides a way of thinking about how children’s texts address and are informed by diverse, complex infl uences, sometimes from a variety of cultures and languages. Transnationalism is not a new phenomenon but is visible in colonial texts which are shaped both by the particular, local ideologies of colonial nations, and also by the common concerns and interests of such nations. The essay draws on two contemporary texts to illustrate the workings of transnationalism: the fi lm Howl’s Moving Castle, and Shaun Tan’s picture book The Arrival. It concludes by considering the concept of transnational literacy as a way of approaching scholarship and teaching in children’s literature.
