Devotional Culture in Late Medieval England and Europe: Diverse Imaginations of Christ’s Life

Christ’s life, as related through the Gospel narratives and early Apocrypha, was subject to a riot of literary-devotional adaptation in the medieval period. This collection provides a series of groundbreaking studies centring on the devotional and cultural significance of Christianity’s pivotal story during the Middle Ages.

The collection represents an important milestone in terms of mapping the meditative modes of piety that characterize a number of Christological traditions, including the Meditationes vitae Christi and the numerous versions it spawned in both Latin and the vernacular. A number of chapters in the volume track how and why meditative piety grew in popularity to become a mode of spiritual activity advised not only to recluses and cenobites as in the writings of Aelred of Rievaulx, but also reached out to diverse lay audiences through the pastoral regimens prescribed by devotional authors such as the Carthusian prior Nicholas Love in England and the Parisian theologian and chancellor of the University of Paris, Jean Gerson.

Through exploring these texts from a variety of perspectives — theoretical, codicological, theological — and through tracing their complex lines of dissemination in ideological and material terms, this collection promises to be invaluable to students and scholars of medieval religious and literary culture.

BELFAST nonagenarians; Nature or Nurture? Immunological, cardiovascular and genetic factors

Nonagenarians are the fastest growing sector of populations across Western European and the developed world. They are some of the oldest members of our societies and survivors of their generation and may help us understand how to age not only longer, but better.The Belfast Longevity Group enlisted the help of 500 community-living, mobile, mentally competent, 'elite' nonagenarians, as part of an ongoing study of ageing. We assessed some immunological, cardiovascular, nutritional and genetic factors and some aspects of their interaction in this group of 'oldest old'.Here we present some of the evidence related to genetic and nutritional factors which seem to be important for good quality ageing in nonagenarians from the Belfast Elderly Longitudinal Free-living Ageing STudy (BELFAST).

Chemoenzymatic Synthesis of Carbasugars (+)-Pericosines A-C from Diverse Aromatic cis-Dihydrodiol Precursors

cis-Dihydrocatechols, derived from biological cis-dihydroxylation of methyl benzoate, iodobenzene and benzonitrile, using the microorganism Pseudomonas putida UV4, were converted into pericosines A, C, and B, respectively. This approach constitutes the shortest syntheses, to date, of these important natural products with densely packed functionalities.

Is the pinning of ordinary dislocations in γ-TiAl intrinsic or extrinsic in nature? A combined atomistic and kinetic Monte Carlo approach

We address the question of the observed pinning of 1/2

Age-specific reproductive investment in female burying beetles: independent effects of state and risk of death

1.How much should an individual invest in reproduction as it grows older? Answering this question involves determining whether individuals measure their age as the time left for future reproduction or as the rate of deterioration in their state. Theory suggests that in the former case individuals should increase their allocation of resources to reproduction as opportunities for future breeding dwindle, and terminally invest when they breed for the last time. In the latter case they should reduce their investment in reproduction with age, either through adaptive reproductive restraint or as a passive by-product of senescence.
2.Here we present the results of experiments on female burying beetles, Nicrophorus vespilloides, in which we independently manipulated the perceived risk of death (by activating the immune system) and the extent of deterioration in state (by changing age of first reproduction and/or prior investment in reproduction).
3.We found that the risk of death and state each independently influenced the extent of reproductive investment. Specifically, we found a state-dependent decline in reproductive investment as females grew older that could be attributed to both adaptive reproductive restraint and senescence. A perceived increase in the risk of death, induced by activation of the immune system, caused females to switch from a strategy of reproductive restraint to terminal investment. Nevertheless, absolute reproductive investment was lower in older females, indicating constraints of senescence.
4.Our results show that a decline in reproductive investment with age does not necessarily constitute evidence of reproductive senescence but can also result from adaptive reproductive restraint.
5.Our results further suggest that the extent of reproductive investment is dependent on several different intrinsic cues and that the particular blend of cues available at any given age can yield very different patterns of investment. Perhaps this explains why age-related reproductive investment patterns seen in nature are so diverse.

The response of small mammals to natural and human-altered edges associated with Afromontane forests of South Africa

An increase in edge area reduces the effective size of habitat fragments and thus the area available for habitat-interior specialists. However, it is unclear how edge effects compare at different ecotones in the same system. We investigated the response of a small mammal community associated with Afromontane forests to edge effects at three different habitat transitions: natural forest to grassland (natural edge, structurally different vegetation types), natural forest to mature plantation (human-altered edge, structurally similar vegetation types) and natural forest to harvested plantation (human-altered edge, structurally different vegetation types). We predicted that edge effects should be less severe at natural ecotones and at similarly structured contiguous vegetation types than human-altered ecotones and differently structured contiguous vegetation types, respectively. We found that forest species seemed to avoid all habitat edges in our study area. Surprisingly, natural edges supported a less diverse small mammal community than human-altered forest edges. However, edge effects were observed deeper into native forests surrounded by mature alien plantations (and more so at harvested plantations) than into native forests surrounded by native grasslands. The net effect of mature plantations was therefore to reduce the functional size of the natural forest by creating a larger edge. We suggest that when plantations are established a buffer zone of natural vegetation be left between natural forests and newly established plantations to mitigate the negative effects of plantation forestry.

Valuing the recreational benefits from the creation of nature reserves in Irish forests

Data from a large-scale contingent valuation study are used to investigate the effects of forest attributes on willingness to pay for forest recreation in Ireland. In particular, the presence of a nature reserve in the forest is found to significantly increase the visitors' willingness to pay. A random utility model is used to estimate the welfare change associated with the creation of nature reserves in all the Irish forests currently without one. The yearly impact on visitors' economic welfare of new nature reserves approaches half a million pounds per annum, exclusive of non-recreational values. (C) 2000 Elsevier Science B.V.

The extent and nature of family alcohol and drug use: Findings from the Belfast Youth Development Study

Using data from an ongoing longitudinal study of adolescent drug use, this study examines the proportion of teenagers living with parents who are problem alcohol or drug users. Around two percent of parents report high levels of problem drinking and one per cent report problem drug use. If a broader definition of hazardous drinking is used, the proportion of teenagers exposed increases to over 15 per cent. When substance use is examined at a family level (taking account of alcohol and drug use amongst dependent children in addition to that of parents), the proportion of families experiencing some form of substance use is considerable. These findings add further support to the call for increased recognition of the needs of dependent children within adult treatment services when working with parents. Likewise, the reduction of harm to children as a result of parent substance use should be an increasingly important priority for family support services. This is likely to be achieved through the closer integration of addiction and family services.
