It's all action, it's all learning: Action learning in SMEs

Purpose - The purpose of this paper is to argue that action learning (AL) may provide a means of successfully developing small to medium-sized enterprises (SMEs). Design/methodology/approach - The literature around SME learning suggests a number of processes are important for SME learning which similarity, it is argued, are encompassed in AL. AL may therefore offer a means of developing SME. This argument is then supported through the results of a longitudinal qualitative evaluation study conducted in the north-west of England, which involved the use of AL in 100 SMEs. Findings - The paper finds that the discursive and critical reflection aspects of the set environment appeared to be of great utility and importance to the SMEs. Sets also had an optimum level of which helped them find "common ground". Once common ground was established set members often continued to network and form alliances outside of the set environment. SME owner-managers could discuss both personal and business. Finally, AL offered the opportunity to take time out of the business and "disengage" with the operational allowing them to become more strategic. Practical implications - In this paper both the literature review and the results of the evaluation suggest AL may offer a means of engaging SMEs in training, which is relevant and useful to them. AL offers a way for policy makers and support agencies to get involved with SME management development while retaining context and naturalistic conditions. Originality/value - This paper attempts to move beyond other articles which assess SME response to government initiatives, through examining the literature around SME learning and constructing a rationale which proposes that AL encompasses many of the learning processes suggested in the literature as effective for SME development. © Emerald Group Publishing Limited

Proprietary Reasons and Joint Action

Some of the reasons one acts on in joint action are shared with fellow participants. But others are proprietary: reasons of one’s own that have no direct practical significance for other participants. The compatibility of joint action with proprietary reasons serves to distinguish the former from other forms of collective agency; moreover, it is arguably a desirable feature of joint action. Advocates of “team reasoning” link the special collective intention individual participants have when acting together with a distinctive form of practical reasoning that purports to put individuals in touch with group or collective reasons. Such views entail the surprising conclusion that one cannot engage in joint action for proprietary reasons. Suppose we understand the contrast between minimal and robust forms of joint action in terms of the extent to which participants act on proprietary reasons as opposed to shared reasons. Then, if the team reasoning view of joint intention and action is correct, it makes no sense to talk of minimal joint action. As soon as the reason for which one participates is proprietary, then one is not, on this view, genuinely engaged in joint action

To Act and Learn: A Bakhtinian Exploration of Action Learning

This paper considers the work of the Russian social philosopher and cultural theorist, Mikhail Mikhailovich Bakhtin as a source of understanding for those involved in action learning. Drawing upon data gathered over two years during the evaluation of 20 action learning sets in the north of England, we will seek to work with the ideas of Bakhtin to consider their value for those involved in action learning. We consider key Bakhtin features such as Making Meaning, Participative Thinking, Theoreticism and Presence, Others and Outsideness, Voices and Carnival to highlight how Bakhtin's can enhance our understanding of the nature of action and learning

'Country life'? Rurality, folk music and 'Show of Hands'

This paper examines the contribution of folk music to understanding the dynamic, fluid and multi-experiential nature of the countryside. Drawing from literature on the geographies of music, it examines the work of 'Show of Hands', a contemporary folk band from Devon in England. Three areas are studied. First, the paper examines the musical style of Show of Hands in order to explore how hybridised, yet distinctive, styles of music emerge in particular places. Second, it demonstrates how Show of Hands' hybrid musical style has become closely associated with the Southwest of England. Finally, within these spatial and hybrid contexts, attention is given to the ways in which their music represents the 'everyday lives of the rural'. Taken together these themes assess the relevance of music in the understanding of rurality as hybrid space. © 2008 Elsevier Ltd. All rights reserved

Gliese 581g as a scaled-up version of Earth: atmospheric circulation simulations

We use three-dimensional simulations to study the atmospheric circulation on the first Earth-sized exoplanet discovered in the habitable zone of an M star. We treat Gliese 581g as a scaled-up version of Earth by considering increased values for the exoplanetary radius and surface gravity, while retaining terrestrial values for parameters which are unconstrained by current observations. We examine the long-term, global temperature and wind maps near the surface of the exoplanet --- the climate. The specific locations for habitability on Gliese 581g depend on whether the exoplanet is tidally-locked and how fast radiative cooling occurs on a global scale. Independent of whether the existence of Gliese 581g is confirmed, our study highlights the use of general circulation models to quantify the atmospheric circulation on potentially habitable, Earth-sized exoplanets, which will be the prime targets of exoplanet discovery and characterization campaigns in the next decade.Comment: Accepted by MNRAS. 15 pages, 13 figures.

The Effects of Carbohydrates, in Isolation and Combined with Caffeine, on Cognitive Performance and Mood - Current Evidence and Future Directions

This review examines the effects of carbohydrates, delivered individually and in combination with caffeine, on a range of cognitive domains and subjective mood. There is evidence for beneficial effects of glucose at a dose of 25 g on episodic memory, but exploration of dose effects has not been systematic and the effects on other cognitive domains is not known. Factors contributing to the differential sensitivity to glucose facilitation include age, task difficulty/demand, task domain, and glucoregulatory control. There is modest evidence to suggest modulating glycemic response may impact cognitive function. The evidence presented in this review identifies dose ranges of glucose and caffeine which improve cognition, but fails to find convincing consistent synergistic effects of combining caffeine and glucose. Whilst combining glucose and caffeine has been shown to facilitate cognitive performance and mood compared to placebo or glucose alone, the relative contribution of caffeine and glucose to the observed effects is difficult to ascertain, due to the paucity of studies that have appropriately compared the effects of these ingredients combined and in isolation. This review identifies a number of methodological challenges which need to be considered in the design of future hypothesis driven research in this area

The Development of a Serum-Free Medium for Use in the Culture of Normal and Malignant Human Melanocytes

This project was initiated to study the use of serum-free medium in the culture of human malignant melanoma cell lines and normal human melanocytes. The development of a. suitable serum-free medium was carried out in two stages using the two melanoma cell lines. Firstly, various supplements were tested for their ability to improve cell growth in the basic culture medium (Ham's F-10) devoid of serum. From this work we established a group of five supplements which we termed the standard supplements and these were added at optimal concentrations to all serum-free media examined by us. This group consisted of human transferrin, bovine serum albumin, Intralipid, insulin and B-mercaptoethanol. Various other supplements also proved stimulatory to melanoma cell growth under serum-free conditions, however even in combination with the standard supplements the level of cell growth achieved was only a fraction of that achieved in medium supplemented with serum. Thus we decided to switch to a richer basic medium and found that our requirements were met by medium MCDB104, a modification of Ham's F-10. The standard supplements were re-optimised in this medium and again various potential supplements were tested. Although cell growth, under serum-free contiitions, was improved it still did not approach the level achieved in serum-containing medium. Thus it was decided that to improve cell growth under serum-free conditions the basic medium would have to bo optimised to suit our requirements. Thus, the second stage in the serum-free medium development was to re-optimise various components of the MCDB104 medium for the two melanoma cell lines. A batch of MCDB104 deficient in 15 components was prepared. Each of the omitted items was then tested over a concentration range and the optimum concentration for each determined for both cell lines. Using the determined concentrations a "new" MCDB104 medium was prepared for each cell line. Again the standard additives were added. Although this optimisation improved cell growth, the level achieved was still lower than that obtained with serum supplementation. To achieve a comparable level of cell growth it was felt that all components of the basic growth medium would require to be optimised for each cell line under study. The development of the serum-free medium was carried out using the two human melanoma cell lines, however it was hoped that any such medium would be useful in the culture of normal human melanocytes. We found that melanocytes would not grow in any of our serum-free media even when supplemented with the routine requirements for melanocyte growth. We also looked at the possibility of improving upon the two methods we elected to use for the culture of melanocytes. This was done by looking at ways in which the problem of fibroblast contamination and overgrowth could be dealt with and also by looking at factors as potential melanocyte stimulants . We found that calmodulin enhanced melanocyte numbers it used in conjunction with the phorbol ester and cholera toxin required routinely for melanocyte growth. Fibroblast contamination was not eliminated by any of our methods. Despite this however we were able to culture normal human melanocytes for periods of up to 6 months

Innovative interstellar explorer

An interstellar "precursor" mission has been under discussion in the scientific community for at least 30 years. Fundamental scientific questions about the interaction of the Sun with the interstellar medium can only be answered with in situ measurements that such a mission can provide. The Innovative Interstellar Explorer (IIE) and its use of Radioisotope Electric Propulsion (REP) is being studied under a NASA "Vision Mission" grant. Speed is provided by a combination of a high-energy launch, using current launch vehicle technology, a Jupiter gravity assist, and long-term, low-thrust, continuous acceleration provided by an ion thruster running off electricity provided by advanced radioisotope electric generators. A payload of ten instruments with an aggregate mass of ~35 kg and requiring ~30 W has been carefully chosen to address the compelling science questions. The nominal 20-day launch window opens on 22 October 2014 followed by a Jupiter gravity assist on 5 February 2016. The REP system accelerates the spacecraft to a "burnout" speed of 7.8 AU per year at 104 AU on 13 October 2032 (Voyager 1's current speed is ~3.6 AU/yr). The spacecraft will return at least 500 bits per second from at least 200 AU ~30 years after launch. Additional (backup) launch opportunities occur every 13 months to early 2018. In addition to addressing basic heliospheric science, the mission will ensure continued information on the far-heliospheric galactic cosmic ray population after the Voyagers have fallen silent and as the era of human Mars exploration begins

Team reasoning and intentional cooperation for mutual benefit

This paper proposes a concept of intentional cooperation for mutual benefit. This concept uses a form of team reasoning in which team members aim to achieve common interests, rather than maximising a common utility function, and in which team reasoners can coordinate their behaviour by following pre-existing practices. I argue that a market transaction can express intentions for mutually beneficial cooperation even if, extensionally, participation in the transaction promotes each party’s self-interest
