Dialogue and science: Innovation in policy-making and the discourse of public engagement in the UK
This paper examines the way in which innovation in science policy in the UK over the last 25 years has been built around a discourse of changing preferences for modes of communication with citizens. The discussion, framed in debates and developments that deal with deliberative democracy and public engagement, draws on discourse analysis of key policy documents, statements made by members of the science policy network, and on interviews with public engagement practitioners. The relationship between science and society emerges as a 25-year old project of crisis management organised into three distinct models: public understanding of science,public engagement, and public dialogue. The analysis questions the existing narrative of progress and evolution constructed around key switch points, highlights the overwhelming influence\ud
of public understanding of science approaches, and attends to the question of the viability of public dialogue as the mainstream activity in science communication and policy-making
A liquid profession: An ecological approach to the theory and knowledge that underpin the practice of public relations
This is a conceptual essay that explores the concept of knowledge as it relates to PR. It suggests an ecological knowledge architecture as a lens through which to understand the theories and concepts that support practice. It does so by drawing on the work of Zygmunt Bauman and his reflections on liquid modernity to inform and shape thinking and uses it as a thread to help synthesise scholarship from PR literature, knowledge and career scholarship and debates around professionalisation. It argues that by sub-dividing knowledge into explanatory, interventionist and practice principles greater clarity can be given to the know-how (functional skills) and know-that (theoretical knowledge) of PR. Additionally, by overlaying a postmodernist and liquid concept to this tripartite division of knowledge PR can be well placed to take advantage of the change in careers and capabilities necessary for work in the twenty-first century
Limitations of Fe^(2+) and Mn^(2+) site occupancy in tourmaline: Evidence from Fe^(2+)- and Mn^(2+)-rich tourmaline
Fe^(2+)- and Mn^(2+)-rich tourmalines were used to test whether Fe^(2+) and Mn^(2+) substitute on the Z site of tourmaline to a detectable degree. Fe-rich tourmaline from a pegmatite from Lower Austria was characterized by crystal-structure refinement, chemical analyses, and Mössbauer and optical spectroscopy. The sample has large amounts of Fe^(2+) (~2.3 apfu), and substantial amounts of Fe^(3+) (~1.0 apfu). On basis of the collected data, the structural refinement and the spectroscopic data, an initial formula was determined by assigning the entire amount of Fe^(3+) (no delocalized electrons) and Ti^(4+) to the Z site and the amount of Fe^(2+) and Fe^(3+) from delocalized electrons to the Y-Z ED doublet (delocalized electrons between Y-Z and Y-Y): X(Na_(0.9)Ca_(0.1)) ^Y(Fe^(2+)_(2.0)Al_(0.4)Mn^(2+)_(0.3)Fe^(3+)_(0.2)) ^Z(Al_(4.8)Fe^(3+)_(0.8)Fe^(2+)_(0.2)Ti^(4+)_(0.1)) ^T(Si_(5.9)Al_(0.1))O_(18) (BO_3)_3^V(OH)_3 ^W[O_(0.5)F_(0.3)(OH)_(0.2)] with α = 16.039(1) and c = 7.254(1) Å. This formula is consistent with lack of Fe^(2+) at the Z site, apart from that occupancy connected with delocalization of a hopping electron.
The formula was further modified by considering two ED doublets to yield: ^X(Na_(0.9)Ca_(0.1)) ^Y(Fe^(2+)_(1.8)Al_(0.5)Mn^(2+)_(0.3)Fe^(3+)_(0.3)) ^Z(Al_(4.8)Fe^(3+)_(0.7)Fe^(2+)_(0.4)Ti^(4+)_(0.1)) ^T(Si_(5.9_Al_(0.1))O_(18) (BO_3)_3 ^V(OH)_3 ^W[O_(0.5)F_(0.3)(OH)_(0.2)]. This formula requires some Fe^(2+) (~0.3 apfu) at the Z site, apart from that connected with delocalization of a hopping electron. Optical spectra were recorded from this sample as well as from two other Fe^(2+)-rich tourmalines to determine if there is any evidence for Fe^(2+) at Y and Z sites. If Fe^(2+) were to occupy two different 6-coordinated sites in significant amounts and if these polyhedra have different geometries or metal-oxygen distances, bands from each site should be observed. However, even in high-quality spectra we see no evidence for such a doubling of the bands. We conclude that there is no ultimate proof for Fe^(2+) at the Z site, apart from that occupancy connected with delocalization of hopping electrons involving Fe cations at the Y and Z sites.
A very Mn-rich tourmaline from a pegmatite on Elba Island, Italy, was characterized by crystal-structure determination, chemical analyses, and optical spectroscopy. The optimized structural formula is ^X(Na_(0.6)□_(0.4)) ^Y(Mn^(2+)_(1.3)Al_(1.2)Li_(0.5)) ^ZAl_6 ^TSi_6O_(18) (BO_3)_3 ^V(OH)_3 ^W[F_(0.5)O_(0.5)], with α = 15.951(2) and c = 7.138(1) Å. Within a 3σ error there is no evidence for Mn occupancy at the Z site by refinement of Al ↔ Mn, and, thus, no final proof for Mn^(2+) at the Z site, either.
Oxidation of these tourmalines at 700–750 °C and 1 bar for 10–72 h converted Fe^(2+) to Fe^(3+) and Mn^(2+) to Mn^(3+) with concomitant exchange with Al of the Z site. The refined ^ZFe content in the Fe-rich tourmaline increased by ~40% relative to its initial occupancy. The refined YFe content was smaller and the distance was significantly reduced relative to the unoxidized sample. A similar effect was observed for the oxidized Mn^(2+)-rich tourmaline. Simultaneously, H and F were expelled from both samples as indicated by structural refinements, and H expulsion was indicated by infrared spectroscopy. The final species after oxidizing the Fe^(2+)-rich tourmaline is buergerite. Its color had changed from blackish to brown-red. After oxidizing the Mn^(2+)-rich tourmaline, the previously dark yellow sample was very dark brown-red, as expected for the oxidation of Mn^(2+) to Mn^(3+). The unit-cell parameter α decreased during oxidation whereas the c parameter showed a slight increase
Professionalizing corporate professions: Professionalization as identity project
Professional bodies have traditionally played a core role in professionalization, setting the ideals for professional identity, knowledge and practice. However, the emergence of corporate professions has problematized the role of the professional body in contemporary professionalization. This article examines the role of the professional body and its ability to resonate with practitioners’ professional identity construction through empirical analysis of public relations. The article introduces the concept of professionalization as identity project as another means by which to understand attempts at social closure in emergent corporate professions. For professionalization as identity project to be fully realized, the research suggests the blending of traditional discourses of professionalism with emergent discourses of entrepreneurialism is required. Consequently, the study highlights that corporate professionalization as identity project reflects the contemporary tensions and contradictions between the lived reality and orthodox ideology of ‘being a professional’
The worldwide C3S CORDEX grand ensemble: A major contribution to assess regional climate change in the IPCC AR6 Atlas
peer reviewedAbstract
The collaboration between the Coordinated Regional Climate Downscaling Experiment (CORDEX) and the Earth System Grid Federation (ESGF) provides open access to an unprecedented ensemble of Regional Climate Model (RCM) simulations, across the 14 CORDEX continental-scale domains, with global coverage. These simulations have been used as a new line of evidence to assess regional climate projections in the latest contribution of the Working Group I (WGI) to the IPCC Sixth Assessment Report (AR6), particularly in the regional chapters and the Atlas.
Here, we present the work done in the framework of the Copernicus Climate Change Service (C3S) to assemble a consistent worldwide CORDEX grand ensemble, aligned with the deadlines and activities of IPCC AR6. This work addressed the uneven and heterogeneous availability of CORDEX ESGF data by supporting publication in CORDEX domains with few archived simulations and performing quality control. It also addressed the lack of comprehensive documentation by compiling information from all contributing regional models, allowing for an informed use of data. In addition to presenting the worldwide CORDEX dataset, we assess here its consistency for precipitation and temperature by comparing climate change signals in regions with overlapping CORDEX domains, obtaining overall coincident regional climate change signals. The C3S CORDEX dataset has been used for the assessment of regional climate change in the IPCC AR6 (and for the interactive Atlas) and is available through the Copernicus Climate Data Store (CDS)
Understanding Learning in Senior Public Relations Practices: from boundary spanning to boundary dwelling
Purpose Over the last 50 years the social legitimacy of public relations has improved by standardising and monitoring the education and training of its practitioners. While successful in developing a professional development trajectory from novice to competent practitioner, the profession has struggled to fully understand the development trajectory of its senior public relations practitioners. The diversity of occupational contexts in which public relations is practised, the condition of professional seniority and the knowledges and tools required for working at occupational boundaries is challenging for senior public relations practitioners. It is also a challenge therefore, for the profession to develop and support the learning required for senior practice beyond competency frameworks. Design/methodology/approach This article employs socio-cultural learning theory and supporting empirical evidence gained in semi-structured interviews with senior practitioners in the field to explore what senior practice entails and how senior professionals learn. Findings Communities of practice is useful for understanding novice practitioner learning but has insufficient explanatory power for understanding senior practitioner learning. There is an urgent need for support for senior public relations learning that moves beyond reified competency frameworks and enables senior practitioners to function autonomously outside the core community of practice. Seniority requires its learners to embrace uncertainty and confront the challenge of creating new knowledges and practices in the everyday of their professional lives. Originality/value ‘Communities of practice’ has been influential in the fields of management and organisations (Bolisani and Scarso, 2014). This article employs the idea of a learning process that takes place in ‘constellations of practices’ (Wenger, 1998) to offer a view of senior practice as boundary dwelling (Engestrom, 2009) rather than boundary spanning and learning as situated (Lave and Wenger, 1991) in the liminal spaces those boundaries provide
