The professionalization of festival organizations : A relational approach to knowledge management

In this article we examine the emergence of knowledge management (KM) within the professionalisation of festivals and events. The growing complexity of festival management places pressure on organisations to effectively manage ‘knowledge’ in order to succeed. Knowledge is commonly conceptualised as information that can be stored or itemised through checklists. We offer an alternative conceptualisation of KM as a relational construction shaped by the organisational culture and structure. We develop this relational approach through a case study of the Queensland Music Festival (QMF) to examine the construction of KM roles and responsibilities. Our ethnographic research and qualitative analysis identifies how QMF implicitly utilises chief knowledge officer, knowledge broker, and knowledge worker roles. These roles were successfully performed over a short duration and yet they were not defined or explicitly stated. We discuss how the culture and spatial organisation of work teams contributed to a collective understanding of the value of sharing and creating knowledge. With growing professionalisation we argue that festival organisations will increasingly develop a more self-conscious awareness of the significance of KM language and practice. The findings will enable festival managers to better understand how KM processes are embedded within an organisational culture and contribute to organisational learning.Peer reviewedFinal Accepted Versio

Molecular Fullerides

The closed shell structures of certain all-carbon fragments originally observed in mass spectroscopy experiments leads to the enhanced stability of these species, known as fullerenes, which have excited sufficient interest amongst chemists and physicists over the last decade to warrant the award of the 1996 Nobel Prize for Chemistry to their discoverers. ¶ Studies of the stability, symmetry, and consequent remarkable properties of fullerenes began in earnest in 1991 with the development of a technique enabling the production and purification of macroscopic quantities of material. The best known and most widely studied fullerene is the truncated icosahedral C60 molecule, which forms the basis of the present work

Tomography of atomic number and density of materials using dual-energy imaging and the Alvarez and Macovski attenuation model

Dual-energy computed tomography and the Alvarez and Macovski [Phys. Med. Biol. 21, 733 (1976)] transmitted intensity (AMTI) model were used in this study to estimate the maps of density (ρ) and atomic number (Z) of mineralogical samples. In this method, the attenuation coefficients are represented [Alvarez and Macovski, Phys. Med. Biol. 21, 733 (1976)] in the form of the two most important interactions of X-rays with atoms that is, photoelectric absorption (PE) and Compton scattering (CS). This enables material discrimination as PE and CS are, respectively, dependent on the atomic number (Z) and density (ρ) of materials [Alvarez and Macovski, Phys. Med. Biol. 21, 733 (1976)]. Dual-energy imaging is able to identify sample materials even if the materials have similar attenuation coefficients at single-energy spectrum. We use the full model rather than applying one of several applied simplified forms [Alvarez and Macovski, Phys. Med. Biol. 21, 733 (1976); Siddiqui et al., SPE Annual Technical Conference and Exhibition (Society of Petroleum Engineers, 2004); Derzhi, U.S. patent application 13/527,660 (2012); Heismann et al., J. Appl. Phys. 94, 2073–2079 (2003); Park and Kim, J. Korean Phys. Soc. 59, 2709 (2011); Abudurexiti et al., Radiol. Phys. Technol. 3, 127–135 (2010); and Kaewkhao et al., J. Quant. Spectrosc. Radiat. Transfer 109, 1260–1265 (2008)]. This paper describes the tomographic reconstruction of ρ and Z maps of mineralogical samples using the AMTI model. The full model requires precise knowledge of the X-ray energy spectra and calibration of PE and CS constants and exponents of atomic number and energy that were estimated based on fits to simulations and calibration measurements. The estimated ρ and Z images of the samples used in this paper yield average relative errors of 2.62% and 1.19% and maximum relative errors of 2.64% and 7.85%, respectively. Furthermore, we demonstrate that the method accounts for the beam hardening effect in density (ρ) and atomic number (Z) reconstructions to a significant extent.S.J.L., G.R.M., and A.M.K. acknowledge funding through the DigiCore consortium and the support of a linkage grant (LP150101040) from the Australian Research Council and FEI Company

Critical moments of (un)doing doctoral supervision: : Collaborative writing as rhizomatic practice

This document is the Accepted Manuscript version of the following article: Simone Fullagar, Adele Pavlidis, and Raphaela Stadler, ‘Critical moments of (un)doing doctoral supervision: collaborative writing as rhizomatic practice’, Knowledge Cultures, August 2015. The Version of Record is available online at doi: https://doi.org/10.22381/KC5420173. Published by Addleton Academic Publishers, New York.Despite the proliferation of doctoral training courses within universities, little attention is paid to the complexity of supervision as a process of becoming for both students and supervisors. As post-qualitative researchers we explore how collaborative writing can be mobilised as a rhizomatic practice to open up engagements with supervision that counter hierarchical master/apprentice models of knowledge transmission. Researching-writing through our own knowledge practices and affective investments we reflexively engage with supervision as multiplicity. We created a more democratic learning alliance through an electronic writing forum. These collaborative e-writing practices generated insights into the critical moments that disrupted the doctoral experience (writers block, self-doubt, misunderstanding). We theorise collaborative writing as a rhizomatic practice that refuses ontological assumptions of linearity, causality and rationality, instead following the embodied lines of thought, affective intensities and problematics that haunt the supervision relationship. We recast supervision as an improvisation through which academic dilemmas/possibilities are negotiated and performed anew.Peer reviewe

Appreciating Formal and Informal Knowledge Transfer Practices within Creative Festival Organizations

This document is the Accepted Manuscript version of the following article: Raphaela Stadler, and Simone Fullagar, "Appreciating formal and informal knowledge transfer practices within creative festival organizations", Journal of Knowledge Management, Vol. 20 (1): 146-161, January 2016, DOI: https://doi.org/10.1108/JKM-11-2014-0484.Purpose – Problem-solving approaches to research have dominated the not-for-profit festival management field. Little attention has been paid to how festival organizations successfully create cultures where knowledge transfer is practised within the high intensity of a festival lifecycle. Drawing upon insights from Social Practice Theory and Appreciative Inquiry (AI), our purpose in this article is to offer a different conceptual approach to understanding how knowledge transfer ‘works’ as an organizational practice to produce a collaborative festival culture. Design/methodology/approach - This article draws upon an ethnographic case study with the highly acclaimed Queensland Music Festival organization in Australia. The research questions and methods were framed around an appreciative approach that identified formal and informal practices that ‘worked’ rather than a conventional problem focused analysis. Findings – Our research focused on appreciating the cultural context that shaped the interrelationships between formal and informal knowledge transfer practices that enabled trust and collaboration. We identified a range of knowledge transfer practices that contributed to the creation of a shared festival ethos and the on-going sustainability of the festival vision. Practical implications - The not-for-profit sector brings numerous challenges for festival organizations and there is a need to appreciate how collaborative and creative knowledge transfer can occur formally and informally. Festival organizers can benefit from understanding the relational and practice dimensions of knowledge management as they are performed within specific organisational contexts. Originality/value – An appreciative understanding of knowledge transfer practices has not yet been applied to not-for-profit festival organizations where problem-solving approaches dominate the field.

An ethnographic exploration of knowledge practices within the Queensland Music Festival

Purpose – The purpose of this paper is to examine the utilisation and application of reflexive ethnography as an interpretative methodology for researching knowledge practices within festival organisations. Design/methodology/approach – The ethnographic approach incorporates two methods of data collection in the research design; participant observation and in-depth interviews. Findings – The research identified that knowledge management practices and processes are often invisible to festival staff when they are embeddedwithin a cohesive organisational culture. Ethnography enables the researcher to make explicit the tacit and normalised ways of working that contribute to the success (and failure) of festival organisations to manage knowledge. The immersion of the researcher in the ethnographic process provided a rich understanding of the relational dimension of knowledge management that would be difficult to elicit from in-depth interviews alone. Research limitations/implications – New fields of study require a range of research methodologies to inform theoretical and practice-based knowledge related to event participation and management. This article contributes to the growing event management literature through a unique focus on ethnography as a research method that offers a deeper understanding of knowledge practices within festival organisations. Originality/value – Limited research has applied an ethnographic approach to festival and event management. This article builds upon early adopters and provides critical insight into the benefits and constraints of ethnographic research.Peer reviewe

Radio tomography and borehole radar delineation of the McConnell nickel sulfide deposit, Sudbury, Ontario, Canada

In an effort to reduce costs and increase revenues at mines, there is a strong incentive to develop high-resolution techniques both for near-mine exploration and for delineation of known orebodies To investigate the potential of high-frequency EM techniques for exploration and delineation of massive sulfide orebodies, radio frequency electromagnetic (RFEM) and ground-penetrating radar (GPR) surveys were conducted in boreholes through the McConnell massive nickel-copper sulfide body near Sudbury, Ontario, from 1993-1996. Crosshole RFEM data were acquired with a JW-4 electric dipole system between two boreholes on section 2720W. Ten frequencies between 0.5 and 5.0 MHz were recorded. Radio signals propagated through the Sudbury Breccia over ranges of at least 150 m at all frequencies. The resulting radio absorption tomogram clearly imaged the McConnell deposit over 110 m downdip. Signal was extinguished when either antenna entered the sulfide body. However, the expected radio shadow did not eventuate when transmitter and receiver were on opposite sides of the deposit. Two-dimensional modeling suggested that diffraction around the edges of the sulfide body could not account for the observed held amplitudes. It was concluded at the time that the sulfide body is discontinuous; according to modeling, a gap as small as 5 m could have explained the observations. Subsequent investigations by INCO established that pick-up in the metal-cored downhole cables was actually responsible for the elevated signal levels. Both single-hole reflection profiles and crosshole measurements were acquired using RAMAC borehole radar systems, operating at 60 MHz. Detection of radar reflections from the sulfide contact was problematic. One coherent reflection was observed from the hanging-wall contact in single-hole reflection mode. This reflection could be traced about 25 m uphole from the contact. In addition to unfavorable survey geometry, factors which may have suppressed reflections included host rock heterogeneity, disseminated sulfides, and contact irregularity. Velocity and absorption tomograms were generated in the Sudbury Breccia host rock from the crosshole radar. Radar velocity was variable, averaging 125 m/mus, while absorption was typically 0.8 dB/m at 60 MHz. Kirchhoff-style 2-D migration of later arrivals in the crosshole radargrams defined reflective zones that roughly parallel the inferred edge of the sulfide body. The McConnell high-frequency EM surveys established that radio tomography and simple radio shadowing are potentially valuable for near- and in-mine exploration and orebody delineation in the Sudbury Breccia. The effectiveness of borehole radar in this particular environment is less certain

Apollo 14: Some geochemical aspects

Chemical analyses were obtained for five samples of Apollo 14 regolith fines, three 14230 core samples, soil clod 14049, breccias 14305 and 14319, 14310 basalt, and some separated phases. The chemical uniformity of these Apollo 14 samples indicates thorough mixing and/or uniform source rocks. Basalt 14310 can be matched well in composition by a four to one mixture of soil and plagioclase. The Eu(2+)/Eu(3+) ratios calculated for 14310 pigeonite and plagioclase are similar to those for Apollo 12 and 15 mare-type basalt phases; this indicates similar redox conditions. Apollo 14 samples are chemically similar to Apollo 12 and 15 KREEP as distinct from Apollo 11, 12, and 15 and Luna 16 mare-type basalts

Conductivity tomography at two frequencies

We present a new approach for crosshole radio tomography. Conductivity images of the investigated area are reconstructed from the ratio of the electric field intensities measured at two similar frequencies. The method largely avoids assumptions about the radiation pattern and in-situ intensity of the transmitting antenna, which introduce errors in conventional single-frequency crosshole electromagnetic-absorption tomography. Application of the method to field data achieved an improvement in resolution of anomalies over traditional single-frequency absorption tomography. The dual-frequency method is not a universal approach; it is suitable for moderately conductive media (>0.01 S/m) over the approximate frequency range 1-100 MHz
