Overlay journals, repositories and the evolution of scholarly communication

This paper examines the part overlay journals can play in developing new roles for repositories in the scholarly communication process. This requires that we answer some outstanding questions about the overlay journal model: · How are overlay journals distinct from other overlay services and other journals? · What business models are applicable? · What opportunities do overlay journals offer to repositories? And, perhaps most importantly: · What value can an overlay journal bring to the process of scholarly communication? As a result of the answer to the first of these questions, this paper gives a definition of an overlay journal as an entity that performs all the activities of a scholarly journal and relies on structural links with one or more archives or repositories to perform its activities. It finds that the overlay journals that already exist use a variety of business models, which means that repositories can engage with overlay journals in many different ways. Research and practice show that overlay journals offer new possibilities for publishers, repositories, authors and readers alike, and as such have a great deal to offer to scholarly communication

Researching girls and violence: facing the dilemmas of fieldwork

This paper explores key methodological and analytical issues encountered in an exploratory study of teenage girls' views and experiences of violence, carried out in Scotland. Researching the ways in which girls conceptualize, experience and use violence raises a number of dilemmas due in part to the sensitive nature of the research topic, and the age and gender of those taking part. Drawing on feminist debates about objectivity, the role of the researcher, power relationships in the production of knowledge, and representation, this article highlights the difficulties of adapting such principles to the day-to-day practicalities of conducting empirical research on girls and violence. It shows how the research itself has been enhanced by having to engage with and work through this complexity

Leprosy and childhood

A CAJM article on leprosy and childhood in 1950's Africa.Disabilities in young people stir the emotions easily. There is an immediate response to children who cannot see or who have been crippled by accident or disease. Expressions such as “stricken,” “handicapped for life” and “unable to join in the games of other children” are a measure of the sympathy that is awakened —a feeling, however, that does not necessarily follow them as easily as they get older, when the consequences of their limitations may be greater. It is, therefore, not difficult to regard disease in children as essentially different from that in adults. Certain conditions one expects to see predominantly in children just as others appear only in the more elderly. When considering those diseases that are common to all ages we ought to be certain that our emotional regard for the child is not causing us to put into separate houses what really belong to the same room

Production of light pseudoscalars in external electromagnetic fields by the Schwinger mechanism

We generalize the Schwinger mechanism and calculate the probability of the decay of intense electromagnetic fields to pseudoscalar particles. We also point out that our estimate for axion emission in a previous paper was incorrect.Comment: 25 pages including 9 figures. Version that matches published versio

Habitat Modeling of Alien Plant Species at Varying Levels of Occupancy

Distribution models of invasive plants are very useful tools for conservation management. There are challenges in modeling expanding populations, especially in a dynamic environment, and when data are limited. In this paper, predictive habitat models were assessed for three invasive plant species, at differing levels of occurrence, using two different habitat modeling techniques: logistic regression and maximum entropy. The influence of disturbance, spatial and temporal heterogeneity, and other landscape characteristics is assessed by creating regional level models based on occurrence records from the USDA Forest Service’s Forest Inventory and Analysis database. Logistic regression and maximum entropy models were assessed independently. Ensemble models were developed to combine the predictions of the two analysis approaches to obtain a more robust prediction estimate. All species had strong models with Area Under the receiver operator Curve (AUC) of >0.75. The species with the highest occurrence, Ligustrum spp., had the greatest agreement between the models (93%). Lolium arundinaceum had the most disagreement between models at 33% and the lowest AUC values. Overall, the strength of integrative modeling in assessing and understanding habitat modeling was demonstrated

Symmetries, Horizons, and Black Hole Entropy

Black holes behave as thermodynamic systems, and a central task of any quantum theory of gravity is to explain these thermal properties. A statistical mechanical description of black hole entropy once seemed remote, but today we suffer an embarrassment of riches: despite counting very different states, many inequivalent approaches to quantum gravity obtain identical results. Such ``universality'' may reflect an underlying two-dimensional conformal symmetry near the horizon, which can be powerful enough to control the thermal characteristics independent of other details of the theory. This picture suggests an elegant description of the relevant degrees of freedom as Goldstone-boson-like excitations arising from symmetry breaking by the conformal anomaly.Comment: 6 pages; first prize essay, 2007 Gravity Research Foundation essay contes
