Idea Networking: Constructing a Pragmatic Conceptual Frame for Action Research Interventions

Action research interventions require use of some form of conceptual frame to guide and evaluate the intervention. Pragmatism offers an explanation of ideas that enables this conceptual frame to be constructed inductively from diverse participants’ ideas. They define ideas as experienced patterns of activity. The purpose of this paper is to explain why and how this pragmatic explanation of ideas can be used to induce an action research conceptual frame. As a demonstration, the paper inducts (emerges) a conceptual frame using idea networking for service providers in an emerging cultural accommodation industry. 50 h of interviews and site visits provided 117 individual idea statements which were networked. The conceptual frame that emerged had five elements: sufficient-legitimation, selected-market, inclusive-boomi, appropriately-financial, and collaboratively-empowered. This provides a coordinated, multi-part, way of evaluating any possible future changes.     

A luminous quasar at a redshift of z = 7.085

The intergalactic medium was not completely reionized until approximately a billion years after the Big Bang, as revealed by observations of quasars with redshifts of less than 6.5. It has been difficult to probe to higher redshifts, however, because quasars have historically been identified in optical surveys, which are insensitive to sources at redshifts exceeding 6.5. Here we report observations of a quasar (ULAS?J112001.48+064124.3) at a redshift of 7.085, which is 0.77 billion years after the Big Bang. ULAS?J1120+0641 has a luminosity of 6.3 × 10(13)L(⊙) and hosts a black hole with a mass of 2 × 10(9)M(⊙) (where L(⊙) and M(⊙) are the luminosity and mass of the Sun). The measured radius of the ionized near zone around ULAS?J1120+0641 is 1.9?megaparsecs, a factor of three smaller than is typical for quasars at redshifts between 6.0 and 6.4. The near-zone transmission profile is consistent with a Lyα damping wing, suggesting that the neutral fraction of the intergalactic medium in front of ULAS?J1120+0641 exceeded 0.1.

Methanotrophy below pH 1 by a new Verrucomicrobia species

Mud volcanoes, mudpots and fumaroles are remarkable geological features characterized by the emission of gas, water and/or semi-liquid mud matrices with significant methane fluxes to the atmosphere (10(-1) to 10(3) t y(-1)). Environmental conditions in these areas vary from ambient temperature and neutral pH to high temperatures and low pH. Although there are strong indications for biological methane consumption in mud volcanoes, no methanotrophic bacteria are known that would thrive in the hostile conditions of fumaroles (temperatures up to 70 degrees C and pH down to 1.8). The first step in aerobic methane oxidation is performed by a soluble or membrane-bound methane mono-oxygenase. Here we report that pmoA (encoding the beta-subunit of membrane-bound methane mono-oxygenase) clone libraries, made by using DNA extracted from the Solfatara volcano mudpot and surrounding bare soil near the fumaroles, showed clusters of novel and distant pmoA genes. After methanotrophic enrichment at 50 degrees C and pH 2.0 the most distant cluster, sharing less than 50% identity with any other described pmoA gene, was represented in the culture. Finally we isolated an acidiphilic methanotrophic bacterium Acidimethylosilex fumarolicum SolV belonging to the Planctomycetes/Verrucomicrobia/Chlamydiae superphylum, 'outside' the subphyla of the Alpha- and Gammaproteobacteria containing the established methanotrophs. This bacterium grows under oxygen limitation on methane as the sole source of energy, down to pH 0.8--far below the pH optimum of any previously described methanotroph. A. fumarolicum SolV has three different pmoA genes, with two that are very similar to sequences retrieved from the mudpot. Highly homologous environmental 16S rRNA gene sequences from Yellowstone Park show that this new type of methanotrophic bacteria may be a common inhabitant of extreme environments. This is the first time that a representative of the widely distributed Verrucomicrobia phylum, of which most members remain uncultivated, is coupled to a geochemically relevant reaction.     

The Continuous Improvement Grid: An Empirical Investigation into the Effectiveness of a Systems,and Action Research,Based Continuous Improvement Intervention,for ‘New’ Organisation Development

This paper is a rare example of a large scale (n = 1310), positivist, evaluation of an action research program. It documents how the Royal Navy used the principles of scholarly consulting and pragmatic science to develop, apply and review a systems based tool, and associated ‘new organisation development’ intervention, to help staff explore and share perceptions of working practices, in order to expand their awareness of their current work situation and so uncover opportunities for improvement. Survey results suggest that the majority of individuals found the interventions valuable and participants in the events enjoyed significantly higher levels of understanding of the organisation, and greater collective, and individual, benefit from it. Findings also provide empirical evidence of the importance of involvement to making successful change, especially when dealing with the change averse. Overall the experience, of which the action research based study and associated positivist survey were part, reinforce the importance of what is described as ‘normative realigning pedagogy’—helping people change by facilitating their generation of new forms of understanding.     

Abundance and condition indices of coyotes on Hart Mountain National Antelope Refuge, Oregon

U.S. Fish and Wildlife Service staff at Hart Mountain National Antelope Refuge (HMNAR), southeastern Oregon, documented high pronghorn ( Antilocapra americana ) fawn mortality, subsequent low fawn recruitment, and declining pronghorn numbers from 1996 to 1999. Coyote ( Canis latrans ) predation was the primary cause, accounting for 60-85% of fawn mortalities each year, and fawns were not physiologically predisposed to predation. Therefore, we investigated certain coyote population parameters (age structure, survival, density, physiology) to evaluate how or if these factors influence coyote predation rates on pronghorn fawns. We captured 11 coyotes (5 male and 6 female) in December 1998. Age of captured animals ranged from 1.7 to 10.7 yrs (￣x = 5.0 years), and all coyotes appeared healthy upon capture. There were no known mortalities through December 1999. We estimated pre-whelping (December through February 1997-1999) density from howling surveys conducted within HMNAR to be 0.40-0.53 km -2 . Compared to other published studies, we found significant ( P ≤ 0.05) differences in selected blood parameters (e.g., blood urea nitrogen, total protein, white blood cell counts), indicating coyote nutrition may be marginal to deficient during winter at HMNAR. A high percentage of coyotes (91%) tested positive for serum-neutralizing antibodies to canine parvovirus. We judged that parasite ( Toxascaris spp., Alaria spp., Sarcocystis spp., and Isospora spp.) prevalence and intensity were not high enough to influence coyote condition. Based on our data, the coyote population at HMNAR is old aged, at a relatively high density, and stable, but their nutrition may be marginal to deficient during winter. Presently, we are unable to draw direct conclusions relating the parameters we sampled with predation rates by this unexploited coyote population.     

GLOBAL MANUFACTURING VIRTUAL NETWORK （GMVN）：A REVISITING OF THE CONCEPT AFTER THREE YEARS FIELDWORK

The idea of the global manufacturing virtual network (GMVN) was introduced in 2000 in order to highlight an emerging as well as an alternative manufacturing system which will have strong impacts on industry and implications to management theory. During the last three years, more than thirty companies - based in the electronics, bio-pharmaceuticals, garment, and home electronics appliance industries - have been studied in the UK and China. The research project addresses the emergence of the collaborative manufacturing phenomenon at three levels - sector, system and enabling technology. This paper summarises preliminary research findings from fieldwork conducted over the last three years. It seeks to clarify the characteristics and functionality of GMVN through the case studies and to contrast it to other types of business model, such as the multinational corporations (MNC) and international strategic alliances (ISAs). It also raises some new research questions and themes for further research into GMVN.
