Baseline nitrate concentration in groundwater of the Chalk in south Dorset, UK

Determining the degree of nitrate pollution in Chalk groundwater is difficult without a clear understanding of concentrations naturally present. In the UK, a general shortage of long-term records of nitrate concentrations in Chalk groundwater prevents a full quantification of baseline concentrations. This paper presents late nineteenth and early twentieth century data on nitrate concentrations in Chalk groundwater in south Dorset, UK and compares them with corresponding data for the last 25 years. The nitrate record is instructive in (1) providing an insight into the baseline nitrate concentration of groundwater; (2) defining the level of nitrate pollution in potable supplies from the Chalk aquifer; and (3) identifying the long-term variations in local nitrate concentrations. Over a period exceeding 100 years mean nitrate concentrations increased from 1.04 mg NO3-N l(-1) to 6.37 mg NO3-N l(-1). Anthropogenic modification of the local groundwater composition is not evident in the early nitrate record. Nitrate data throughout this early period reflect natural background concentrations of approximately I mg NO3-N l(-1) Intensified fertilser use and increased livestock numbers are suggested as the fundamental cause of the rise in nitrate concentrations. The implications of the nitrate record for regional hydrogeological processes are discussed. (C) 2003 Elsevier Science B.V. All rights reserved.

A baseline appraisal of water-dependant ecosystem services, the roles they play within desakota livelihood systems and their potential sensitivity to climate change

This report forms part of a larger research programme on 'Reinterpreting the Urban-Rural Continuum', which conceptualises and investigates current knowledge and research gaps concerning 'the role that ecosystems services play in the livelihoods of the poor in regions undergoing rapid change'. The report aims to conduct a baseline appraisal of water-dependant ecosystem services, the roles they play within desakota livelihood systems and their potential sensitivity to climate change. The appraisal is conducted at three spatial scales: global, regional (four consortia areas), and meso scale (case studies within the four regions). At all three scales of analysis water resources form the interweaving theme because water provides a vital provisioning service for people, supports all other ecosystem processes and because water resources are forecast to be severely affected under climate change scenarios. This report, combined with an Endnote library of over 1100 scientific papers, provides an annotated bibliography of water-dependant ecosystem services, the roles they play within desakota livelihood systems and their potential sensitivity to climate change. After an introductory, section, Section 2 of the report defines water-related ecosystem services and how these are affected by human activities. Current knowledge and research gaps are then explored in relation to global scale climate and related hydrological changes (e.g. floods, droughts, flow regimes) (section 3). The report then discusses the impacts of climate changes on the ESPA regions, emphasising potential responses of biomes to the combined effects of climate change and human activities (particularly land use and management), and how these effects coupled with water store and flow regime manipulation by humans may affect the functioning of catchments and their ecosystem services (section 4). Finally, at the meso-scale, case studies are presented from within the ESPA regions to illustrate the close coupling of human activities and catchment performance in the context of environmental change (section 5). At the end of each section, research needs are identified and justified. These research needs are then amalgamated in section 6.

Difference in competence for in vitro proliferation and ex vitro growth of genetically identical mature and juvenile clones of apomictic Malus species

The apomictic system in Malus wits Used Is a model to examine rejuvenation by generating genetically identical tissue culture lines that had two entirely different developmental origins: either embryo-derived tissues (juvenile clones) or somatic tissue from the adult/mature tree (mature clones). These two lines were then subsequently used to examine in vitro difference between mature (M) and juvenile (J) tissues in potential for shoot, root proliferation and ex vitro (glasshouse) growth. The M clones of M. hupehensis and M. toringoides in vitro had significantly fewer total shoots and shoot more than 2 cm in length per proliferating explant than the J clones and also rooted less efficiently. Ex vitro (glasshouse) juvenile clones had shorter internodes, a greater number of leaves and more dry weight compared to their mature counterparts.

Seasonal variations in the developmental competence of bovine oocytes matured in vitro

Ovaries were collected over a period of two years from heifers slaughtered at under 30 months of age and used to harvest 1757 oocytes. After in vitro maturation, fertilisation and culture, the proportions of oocytes and cleaved embryos that developed to blastocysts were significantly higher (P < 0.01) in the autumn, from September to November, than in the spring, from March to May. In contrast, embryo development, as assessed by oocytes that developed to eight or more cells and blastocysts, was lowest (P < 0.01) in the spring. These results were consistent during the two-year study, indicating a seasonal fluctuation in oocyte competence.

Doctoral supervision of colleagues: peeling off the veneer of satisfaction and competence

The nexus of teaching, administration and research activities engaged in by academic staff in higher education means that each individual plays a multitude of roles in relation to colleagues, producing inevitable tensions. One role relationship that epitomizes this extraordinary juggling task is that of doctoral supervisor/supervisee, when both are academic staff in the same institution. The last 10 years has seen an upsurge of research interest in doctoral research students, and government and funding bodies have imposed ever more stringent requirements on supervisors. However, staff pairings have been ignored in this literature and research. This article reports on an exploration that seeks to redress this omission by giving voice to the participants (colleague supervisor or research student), allowing them to articulate constructs about what may be unique in the interaction, thus highlighting factors that support or impede success in the enterprise.

Uneven playing field or falling standards? Chinese students' competence in English.

This paper explores student and teacher perspectives of challenges relating to the levels of competence in English of Chinese students studying overseas from the perspective of critical pedagogy. It draws on two complementary studies undertaken by colleagues at the University of Reading. The first—a research seminar attended by representatives from a wide range of UK universities—presents the views of teachers and administrators; the second draws on four case studies of the language learning of Chinese postgraduate students during their first year of study in the UK, and offers the student voice. Interview and focus group data highlight the limitations of current tests of English used as part of the requirements for university admission. In particular, university teachers expressed uncertainty about whether the acceptance of levels of written English which fall far short of native-speaker competence is an ill-advised lowering of standards or a necessary and pragmatic response to the realities of an otherwise uneven playing field. In spite of this ambivalence, there is evidence of a growing willingness on the part of university teachers and support staff to find solutions to the language issues facing Chinese students, some of which require a more strategic institutional approach, while others rely on greater flexibility on the part of individuals. Although the studies reported in this paper were based on British universities, the findings will also be of interest to those involved in tertiary education in other English-speaking countries which are currently attracting large numbers of Chinese students.

Effects of presenting the baseline risk when communicating absolute and relative risk reductions

This study compares relative and absolute forms of presenting risk information about influenza and the need for vaccination. It investigates whether differences in people's risk estimates and their evaluations of risk information, as a result of the different presentation formats, are still apparent when they are provided with information about the baseline level of risk. The results showed that, in the absence of baseline information, the relative risk format resulted in higher ratings of satisfaction, perceived effectiveness of vaccination, and likelihood of being vaccinated. However, these differences were not apparent when baseline information was presented. Overall, provision of baseline information resulted in more accurate risk estimates and more positive evaluations of the risk messages. It is recommended that, in order to facilitate shared and fully informed decision making, information about baseline level of risk should be included in all health communications specifying risk reductions, irrespective of the particular format adopted.
