Interview with Susan Longley by Andrea L’Hommedieu

Biographical NoteSusan Walsh Longley was born in December, 1955, in Lewiston, Maine, to James B. and Helen Longley. Her father, a successful insurance businessman, ran for governor in 1974 and won election during her senior year in high school. She attended Mt. Holyoke College, graduating in the class of 1978. In 1984-1985, she worked on Senator Mitchell’s Senate staff as a legislative correspondent. She established her own law practice in 1989 and later served as a Maine state senator representing Waldo County. SummaryInterview includes discussion of: family and educational background; her father, former Maine governor Jim Longley and his election as an independent; 1974 Maine gubernatorial campaign; anecdote about being hired by Senator Mitchell; U.S. Senate staff relationships: Gayle Cory, Mary McAleney, Anita Jensen; Topsham overpass issue; working on Mitchell’s Senate staff 1984-85; and environmental correspondence

Derek Mahon's Seascapes Mediated through Greece: Antiquity in Modernity, Nature in Abstraction.

The article investigates various approaches to seascape in selected poems of the contemporary Irish poet, Derek Mahon, set against the background of references to Michael Longley, Seamus Heaney or Odysseus Elytis. The sea provides a perspective that cannot be overestimated in trying to get an insight into the communication and the clash between the culture of the South and the North. The two nations have often glimpsed at their reflection in the mirror of the surrounding seas, their history and mentality determined by their geographical position and largely insular experience. Elements such as the isolation from the mainland; the perception of the sea as a personification of the force ruling over life and death, as a threat and a promise; or the focus on some characteristic natural phenomena such as light or surface dominate the seascape imagery both in Greek and Irish literature. The sea often constitutes a border of antagonistic and complementary worlds: dream and reality, light and darkness, male and female, the real world and the underworld – and the vantage point of the poet changes accordingly. Some poems under discussion also explore a series of myths linked with the sea, the best known of which, the Odyssey, has remained a frame of reference for numerous contemporary Greek and Irish poets. Elytis's Cyclades or Longley's Mayo provide us with examples of 'private homelands'. As Longley once observed, “his part of Mayo” reminds him of Ithaca (sandy and remote) and of Greece in general: “I’ve often thought that that part of Ireland . . . looks like Greece. Or Greece looks like a dust-bowl version of Ireland,” which triggers further deliberations on seascape as the common ground for the two countries. Just as Elytis's Cyclades or Longley's Mayo, Mahon’s Cyclades provide us with examples of 'private homelands'. The focus of this article is Derek Mahon’s seascapes: purely Greek (‘Aphrodite’s Pool’), Irish seen through the prism of the Greek ones (‘Achill’) and purely Irish (‘Recalling Aran’). The level of abstraction in the last category is compared with Odysseus Elytis’s imagery of the Cyclades, while the first poem demystifies a practice which I termed as ‘myth trading’, one of consumerist tourism techniques

Representing Population Dynamics from Administrative and Consumer Registers

This research attempts to derive representative metrics of household dynamics and migration by analysing changes between two annual composite registers of the UK population. Through appropriate data cleaning and linkage techniques, it is possible to match addresses and record changes in their size and composition over a two year period. The paper also demonstrates that it is feasible to approximate migration trends by filtering and matching records of household units and individuals whom are not recorded at the same address in both datasets

Using Big Data to Measure the Demographic Changes in a Gentrifying Neighbourhood

This paper presents the use of a micro-level population dataset constructed from linked administrative and consumer data to model the local demographic changes that have occurred in a given area. The constituents of this database derive from 20 years of linked electoral registers and consumer datasets which when amalgamated represent the vast majority of the adult population. While the component data inputs only include dates, names and addresses, this paper shall demonstrate that a range of novel data linkage exercises can reveal local population trends that were otherwise unavailable from traditional data sources

Calculation of the Phase Behavior of Lipids

The self-assembly of monoacyl lipids in solution is studied employing a model in which the lipid's hydrocarbon tail is described within the Rotational Isomeric State framework and is attached to a simple hydrophilic head. Mean-field theory is employed, and the necessary partition function of a single lipid is obtained via a partial enumeration over a large sample of molecular conformations. The influence of the lipid architecture on the transition between the lamellar and inverted-hexagonal phases is calculated, and qualitative agreement with experiment is found.Comment: to appear in Phys.Rev.
