The RNA sequences and structures that link the two RNA molecules vary, and these differences provide clues as to the role of this feature in the viral lifecycles. This review draws upon examples from different retroviral families. Differences and similarities in both secondary and tertiary structure are discussed. The implication of varying roles for the dimer linkage in related viruses is considered

Seasonality and early modern towns: the timing of baptisms, marriages and burials in England, 1560-1750, with particular reference to towns
The thesis examines the seasonality of baptisms, marriages and burials in early modern towns, and demonstrates that seasonality (which measures how the frequency of vital events varied through the year) is a useful method of examining aspects of social history.
Chapter 1 looks at the background to the use of the demographic tool of seasonality and suggests how seasonality may be able to address some of the concerns of urban historians.
Chapters 2 to 4 discuss the sources and methodology of the study, and the results are summarised in Chapter 5. The baptismal, burial and marriage seasonality patterns are described, and urban patterns are compared and contrasted with rural patterns.
The results are discussed in Chapter 6, which seeks to explain the seasonality patterns, and the similarities and differences between urban and rural patterns, by looking at the context in which they arise, principally living conditions and the prevalence of diseases, and working and leisure patterns. Chapter 7 looks more closely at the transition between urban and rural seasonality patterns.
Plague and intestinal disease, due to overcrowded and insanitary living conditions, created a divergent burial pattern in towns up to 1700. Otherwise, the urban and rural seasonality patterns of all events were basically similar in shape. The crucial distinction between urban and rural seasonality was in the much `flatter' patterns in towns, due largely to the more even and varied routines of urban occupations compared to farming, which was inherently seasonal in its labour demands. It is argued that population size was the significant factor in the development of urban seasonality, with small towns being transitional between the high seasonality of rural parishes and the low seasonality of larger towns
Excavations on St Anne's Hill: A Middle/Late Iron Age site and Anglo-Saxon cemetery at St Anne’s Road, Eastbourne, East Sussex
Archaeological investigations, undertaken in 1997 and 1998, revealed further evidence of an important multi-period site located on the crest and south-east-facing slope of St Anne’s Hill, Eastbourne, East Sussex Around 100 Middle/Late Iron Age storage pits were uncovered: many more than any other non-hillfort site in Sussex and with evidence that grain processing as well as storage may have been carried out at the site. Almost certainly connected are secondary religious offerings deposited within the pits, which were probably perceived as influencing the success or failure of the agricultural cycle. Many of the artefacts – including coins, agricultural tools and querns– were apparently deliberately placed, and even domestic waste like broken pottery and animal bone appears to have been subject to a highly structured pattern of deposition. Soon after the Roman conquest there was a major reorganisation of the landscape with a new field-system and trackway, perhaps as a result of the foundation of villa estates in the area. In the 5th century an Early Anglo-Saxon cemetery was established on the hill, with 193 graves and 11 urned cremations recorded during these excavations. These ranged in date from the 5th and 6th centuries to the 7th century and the accompanying grave goods suggest a community mixed in character; whilst there are examples of richly furnished burials, generally these were people without extremes of material wealth
The Development of the Role of the Actor-Musician in Britain by British Directors Since the 1960s
This thesis will investigate the creation and development by two British
directors, Glen Walford and Bob Carlton, of the use of the actor-musician in
small-scale touring, popular theatre community and subsidised repertory with a
strong community base performance practices from 1960 to 2000. It will argue
that the actor-musician had been established in touring community theatre
companies, where distinctive working methodologies had evolved. Using
previously unpublished archive material and new interviews; this is the first
dedicated academic study to identify the work of these directors as a distinctive
and innovative practice, which has one key strand of musical theatre
performance in Britain since the 1960s. It locates this new body of practice in a
diverse tradition of socially engaged and politically informed theatre that
evolved through times of financial stringency, it will argue nonetheless that the
work of these two directors has primarily creative or artistic validity which was
driven and underpinned by social and political concern.
The thesis will demonstrate that the two directors investigated represent the key
line of continuity in the field of actor-musician practice. Each of these directors
has worked and continued to work in very distinct styles and contexts and
utilised the actor-musician in differing ways. The thesis will employ case studies
in order to demonstrate ways in which the potential and range of the actormusician
was developed in: classic plays, including Shakespeare reworked and
extant musicals; new work that has been specifically conceived and created for
actor-musicians. In conclusion it will evaluate the continuing significance of this
practice within British musical theatre
Against all odds: Embedding new knowledge for event continuity and community well-being.
Ashbourne Royal Shrovetide Football (ARSF) is a sporting event that occurs yearly on Shrove Tuesday and Ash Wednesday in the market town of Ashbourne, in Derbyshire. Sometimes referred to as "mob football," Shrovetide can arguably be perceived as the quintessential sensorial and fully immersive event, being played out across town and involving the entire community. The event is also a unique tourism spectacle and a tool for tourism destination positioning. This article presents some of the results of a larger study that looks at challenges in the matter of events safety and the impacts that this has on event survival and the sustainable development of local communities. Findings highlight the need to support communities to learn from events in order to preserve them as they are essential for the maintenance of a unique and inimitable community identity.N/
