Harnessing social capital : an exploratory investigation of stakeholder disposition in boundary spanning networks

This thesis confronts existing bilateral models of stakeholder management. It is based upon the premise that existing models place insufficient value upon the mediating power of individuals and small groups imbued with social capital within an organisational stakeholder environment. Initially, this study explores and maps the complex theoretical relations between organisations, stakeholders and social capital to construct an argument for addressing stakeholder management from a more plural and holistic perspective. The thesis suggests that rapid advances in social media and social interconnection now enables the sentiment of individual stakeholders to aggregate and rapidly form issue-specific interest groups that harness social capital to influence or act upon organisations. The thesis then continues to suggest that such social aggregation produces boundary spanners who in turn act as attractors for continued group aggregation, leading action against organisations. This is an important re-conceptualisation because organisations will need to recognise and manage this growing phenomenon. The thesis then explores the James Hardie asbestos compensation issue as a revelatory and purposeful case study of this emerging phenomenon. This case illustrates that dissonance may arise between an organisation and its stakeholders where an expectation gap develops between an organisation\u27s activities and community standards - dissonance that may grow within a community, instigating group action that may have a significant impact upon an organisation. Having conceptualised and illustrated this emerging phenomenon, the thesis then moves on to describe the results of a limited pilot field study that explores the first stages of this conceptual development; the development of individual community sentiment about organisational action. The James Hardie case is used as the basis of this investigation. The investigation is based on a historical quasi-longitudinal stakeholder survey of stakeholder perceptions about, and community disposition towards, the James Hardie case through quantitative and qualitative data. Structurally, the research utilises Carroll\u27s (1979) Corporate Social Performance Model as a framework to explore the development of social capital within the stakeholder environment, examining stakeholder perceptions on four levels of organisational activity: economic, legal, ethical and discretionary. The study examines and provides evidence of the first stage of the development of the stakeholder-organisation expectation gap and the growth of community sentiment, a pre-requisite for the subsequent formation of issue-specific interest groups and boundary-spanner action against an organisation. This thesis makes a contribution to current understanding of stakeholder management by arguing for and proposing an extended plural model of stakeholder management - a model that incorporates the emerging reality of social media enabling the aggregation of individual sentiment into social capital, and subsequent community activity. In addition the thesis shows how the existing theory of Carroll provides a framework to investigate how stakeholder sentiment initially develops. In doing so it paves the way for subsequent research to further explore the proposed extension to theory; how social aggregation around issues of sentiment develops and how boundary spanners aggregate that sentiment and convert it into action. In terms of organisational practice, the study concludes by asserting that organisations should engineer a more strategic approach to managing stakeholder relations in order to harness the embedded social capital of community stakeholder groups. The ongoing saga of the James Hardie case illustrates what may happen if organisations do not take such action

Energy input is primary controller of methane bubbling in subarctic lakes

Emission of methane (CH4) from surface waters is often dominated by ebullition (bubbling), a transport mode with high‐spatiotemporal variability. Based on new and extensive CH4 ebullition data, we demonstrate striking correlations (r2 between 0.92 and 0.997) when comparing seasonal bubble CH4 flux from three shallow subarctic lakes to four readily measurable proxies of incoming energy flux and daily flux magnitudes to surface sediment temperature (r2 between 0.86 and 0.94). Our results after continuous multiyear sampling suggest that CH4 ebullition is a predictable process, and that heat flux into the lakes is the dominant driver of gas production and release. Future changes in the energy received by lakes and ponds due to shorter ice‐covered seasons will predictably alter the ebullitive CH4 flux from freshwater systems across northern landscapes. This finding is critical for our understanding of the dynamics of radiatively important trace gas sources and associated climate feedback

Roche tomography of cataclysmic variables - II. Images of the secondary stars in AM Her, QQ Vul, IP Peg and HU Aqr

We present a set of Roche tomography reconstructions of the secondary stars in the cataclysmic variables AM Her, QQ Vul, IP Peg and HU Aqr. The image reconstructions show distinct asymmetries in the irradiation pattern for all four systems that can be attributed to shielding of the secondary star by the accretion stream/column in AM Her, QQ Vul and HU Aqr, and increased irradiation by the bright-spot in IP Peg. We use the entropy landscape technique to derive accurate system parameters (M1, M2, i and γ) for the four binaries. In principle, this technique should provide the most reliable mass determinations available, since the intensity distribution across the secondary star is known. We also find that the intensity distribution can systematically affect the value of γ derived from circular orbit fits to radial velocity variations

Grasping Ideas with the Motor System: Semantic Somatotopy in Idiom Comprehension

Single words and sentences referring to bodily actions activate the motor cortex. However, this semantic grounding of concrete language does not address the critical question whether the sensory–motor system contributes to the processing of abstract meaning and thought. We examined functional magnetic resonance imaging activation to idioms and literal sentences including arm- and leg-related action words. A common left fronto-temporal network was engaged in sentence reading, with idioms yielding relatively stronger activity in (pre)frontal and middle temporal cortex. Crucially, somatotopic activation along the motor strip, in central and precentral cortex, was elicited by idiomatic and literal sentences, reflecting the body part reference of the words embedded in the sentences. Semantic somatotopy was most pronounced after sentence ending, thus reflecting sentence-level processing rather than that of single words. These results indicate that semantic representations grounded in the sensory–motor system play a role in the composition of sentence-level meaning, even in the case of idioms

Engaging "seldom heard" groups in research and intervention development: Offender mental health.

BACKGROUND: People subject to the criminal justice system often have substantially different life-experiences from the general population. Patient and public involvement (PPI) of "seldom heard" groups provides valuable experiential knowledge, enhancing research. OBJECTIVE: To share our jointly developed techniques to ensure the meaningful engagement and contribution of people with lived experience of the criminal justice system (PWLECJS) in research, trial science, intervention theory development and dissemination. METHODS: Commitment to adequate financial resources, appropriate staff skills and adequate time were combined with previous learning. PWLECJS were approached through local community organizations. A group was established and met fortnightly for ten months in an unthreatening environment and had a rolling membership. Ongoing engagement was promoted by the group taking responsibility for the rules, interactive and accessible activities, feeding back tangible impacts, ongoing contact, building a work ethic, joint celebrations, sessions with individual academic researchers and pro-actively managed endings. RESULTS: The Peer Researchers contributed to study documents, training academic researchers, research data collection and analysis, intervention delivery and theory development and trial science. The Peer Researchers gained in confidence and an improved sense of self-worth. The Academic Researchers gained skills, knowledge and an increased openness to being challenged. DISCUSSION AND CONCLUSIONS: PWLECJS can be meaningful included in health research and intervention development. The key elements required are listed. Challenges included differences in priorities for timescales and dissemination, resource limitations and the use of Peer Researchers' names. Further research is required to understand what might be of relevance for other "seldom heard" groups

First faint dual-field phase-referenced observations on the Keck interferometer

Ground-based long baseline interferometers have long been limited in sensitivity by the short integration periods imposed by atmospheric turbulence. The first observation fainter than this limit was performed on January 22, 2011 when the Keck Interferometer observed a K=11.5 target, about one magnitude fainter than its K=10.3 limit. This observation was made possible by the Dual Field Phase Referencing instrument of the ASTRA project: simultaneously measuring the real-time effects of the atmosphere on a nearby bright guide star, and correcting for it on the faint target, integration time longer than the turbulence time scale are made possible. As a prelude to this demonstration, we first present the implementation of Dual Field Phase Referencing on the interferometer. We then detail its on-sky performance focusing on the accuracy of the turbulence correction, and on the resulting fringe contrast stability. We conclude with a presentation of early results obtained with Laser Guide Star AO and the interferometer.Comment: 10 pages, 12 figures, Proc. SPIE 201

ReseArch with Patient and Public invOlvement: a RealisT evaluation - the RAPPORT study

Background Patient and public involvement (PPI) is a prerequisite for many funding bodies and NHS research ethics approval. PPI in research is defined as research carried out with or by the public rather than to, about or for them. While the benefits of PPI have been widely discussed, there is a lack of evidence on the impact and outcomes of PPI in research. Objectives To determine the types of PPI in funded research, describe key processes, analyse the contextual and temporal dynamics of PPI and explore the experience of PPI in research for all those involved. Mechanisms contributing to the routine incorporation of PPI in the research process were assessed, the impact of PPI on research processes and outcomes evaluated, and barriers and enablers to effective PPI identified. Design A three-staged realist evaluation drawing on Normalisation Process Theory to understand how far PPI was embedded within health-care research in six areas: diabetes mellitus, arthritis, cystic fibrosis, dementia, public health and learning disabilities. The first two stages comprised a scoping exercise and online survey to chief investigators to assess current PPI activity. The third stage consisted of case studies tracked over 18 months through interviews and document analysis. The research was conducted in four regions of England. Participants Non-commercial studies currently running or completed within the previous 2 years eligible for adoption on the UK Clinical Research Network portfolio. A total of 129 case study participants included researchers and PPI representatives from 22 research studies, and representatives from funding bodies and PPI networks
