- Background: The dynamics of phosphorus (P) in the environment is important for regulating nutrient cycles in natural and managed ecosystems and an integral part in assessing biological resilience against environmental change. Organic P (P-o) compounds play key roles in biological and ecosystems function in the terrestrial environment being critical to cell function, growth and reproduction.Scope: We asked a group of experts to consider the global issues associated with P-o in the terrestrial environment, methodological strengths and weaknesses, benefits to be gained from understanding the P-o cycle, and to set priorities for P-o research.Conclusions: We identified seven key opportunities for P-o research including: the need for integrated, quality controlled and functionally based methodologies; assessment of stoichiometry with other elements in organic matter; understanding the dynamics of P-o in natural and managed systems; the role of microorganisms in controlling P-o cycles; the implications of nanoparticles in the environment and the need for better modelling and communication of the research. Each priority is discussed and a statement of intent for the P-o research community is made that highlights there are key contributions to be made toward understanding biogeochemical cycles, dynamics and function of natural ecosystems and the management of agricultural systems.

- Aims. We present the spectra of 36 supernovae (SNe) of various types, obtained by the European Supernova Collaboration. Because of the spectral classification and the phase determination at their discovery the SNe did not warrant further study, and the spectra we present are the only ones available for the respective objects. In this paper we present and discuss this material using a new software for the automated classification of SNe spectra. Methods. As a validation of the software, we verify the classification and phase estimate reported for these objects in their discovery/classification circulars. For the comparison, the software uses the library of template spectra of Padova-Asiago Supernova Archive (ASA). Results. For each spectrum of our sample we present a brief, individual discussion, highlighting the main characteristics and possible peculiarities. The comparison with ASA spectra confirms the previous classification of all objects and refines the age estimates. For our software, we determine numerical limits of ""safe"" spectral classification and the uncertainties of the phase determination.

- Objective: To examine the experiences of communication between older people and health and social care providers in six European countries. Methods: Focus groups were carried out with groups of older people (91 focus groups, 391 participants), and health and social care professionals (85 focus groups, 424 participants), in order to gain insights into concepts of good communications. Data collection and analysis continued concurrently according to the method of constant comparison. Results: Different styles of communication between professionals and older people were found to be capable of enhancing or jeopardising dignity. The use of appropriate forms of address, listening, giving people choice, including them, respecting their need for privacy and politeness, and making them feel valued emerged as significant ways to maintain older peoples' sense of self-worth and dignity. Despite being aware of good communication practices, health and social care professionals often failed to implement them. Lack of time, staff, resource scarcity, regulation and bureaucracy were cited as barriers, as was a lack of awareness and effort. Conclusions and practice implications: The findings have important implications for health and social care professionals when they engage with older people. © 2005 Elsevier Ireland Ltd.
