    Inter-organisational knowledge transfer is very important for SMEs. However, compared to knowledge transfer within an organisation, its ‘boundary paradox’ makes its process more complicated and difficult to understand. In order to solve the ‘paradox’, inter-organisational knowledge transfer strategies need to be developed for SMEs. Through a review of the literature on knowledge transfer, this paper proposes an inter-organisational knowledge transfer process model that contains four stages (initiation, selection, interaction and conversion). It classifies three situations in which an SME exchanges knowledge with a customer (whether a larger company or an SME). It then applies a coordinating mechanism to analyse knowledge transfer strategies for the SME when it is a knowledgegiving firm and knowledge-receiving firm respectively, in the different stages of each situation

    We review the history of the discovery of field subgiant stars and their importance in the age dating of the Galactic disk. We use the cataloged data from the Hipparcos satellite in this latter capacity. Based on Hipparcos parallaxes accurate to 10% or better, the absolute magnitude of the lower envelope of the nearly horizontal subgiant sequence for field stars in the H-R diagram for B-V colors between 0.85 and 1.05 is measured to be M_V = 4.03 +/- 0.06. The age of the field stars in the solar neighborhood is found to be 7.9 +/- 0.7 Gyr by fitting the theoretical isochrones for [Fe/H] = +0.37 to the lower envelope of the Hipparcos subgiants. The same grid of isochrones yields ages, in turn, of 4.0 +/- 0.2 Gyr, 6.2 +/- 0.5 Gyr, and 7.5 to 10 Gyr for the old Galactic clusters M67, NGC188, and NGC6791. The ages of both the Galactic disk in the solar neighborhood and of NGC6791 are, nevertheless, likely between 3 and 5 Gyr younger than the oldest halo globular clusters, which have ages of 13.5 Gyr. The most significant results are (1) the supermetallicity of the oldest local disk stars, and (2) the large age difference between the most metal-poor component of the halo and the thick and thin disk in the solar neighborhood. These facts are undoubtedly related and pose again the problem of the proper scenario for the timing of events in the formation of the halo and the Galactic disk in the solar neighborhood.

    Integrating group Delphi, fuzzy logic and expert systems for marketing strategy development:the hybridisation and its effectiveness

    Get PDF
    A hybrid approach for integrating group Delphi, fuzzy logic and expert systems for developing marketing strategies is proposed in this paper. Within this approach, the group Delphi method is employed to help groups of managers undertake SWOT analysis. Fuzzy logic is applied to fuzzify the results of SWOT analysis. Expert systems are utilised to formulate marketing strategies based upon the fuzzified strategic inputs. In addition, guidelines are also provided to help users link the hybrid approach with managerial judgement and intuition. The effectiveness of the hybrid approach has been validated with MBA and MA marketing students. It is concluded that the hybrid approach is more effective in terms of decision confidence, group consensus, helping to understand strategic factors, helping strategic thinking, and coupling analysis with judgement, etc

    Synthetic Nanoparticles for Vaccines and Immunotherapy

    The immune system plays a critical role in our health. No other component of human physiology plays a decisive role in as diverse an array of maladies, from deadly diseases with which we are all familiar to equally terrible esoteric conditions: HIV, malaria, pneumococcal and influenza infections; cancer; atherosclerosis; autoimmune diseases such as lupus, diabetes, and multiple sclerosis. The importance of understanding the function of the immune system and learning how to modulate immunity to protect against or treat disease thus cannot be overstated. Fortunately, we are entering an exciting era where the science of immunology is defining pathways for the rational manipulation of the immune system at the cellular and molecular level, and this understanding is leading to dramatic advances in the clinic that are transforming the future of medicine.1,2 These initial advances are being made primarily through biologic drugs– recombinant proteins (especially antibodies) or patient-derived cell therapies– but exciting data from preclinical studies suggest that a marriage of approaches based in biotechnology with the materials science and chemistry of nanomaterials, especially nanoparticles, could enable more effective and safer immune engineering strategies. This review will examine these nanoparticle-based strategies to immune modulation in detail, and discuss the promise and outstanding challenges facing the field of immune engineering from a chemical biology/materials engineering perspectiveNational Institutes of Health (U.S.) (Grants AI111860, CA174795, CA172164, AI091693, and AI095109)United States.

    Oxygen and nitrogen abundances in nearby galaxies. Correlations between oxygen abundance and macroscopic properties

    Full text link
    We performed a compilation of more than 1000 published spectra of HII regions in spiral galaxies. The oxygen and nitrogen abundances in each HII region were recomputed in a homogeneous way, using the P-method. The radial distributions of oxygen and nitrogen abundances were derived. The correlations between oxygen abundance and macroscopic properties are examined. There is a significant difference between the L-Z relationship obtained here and that based on the oxygen abundances determined through the R_23-calibrations. The oxygen abundance of NGC 5457 recently determined using direct measurements of Te (Kennicutt, Bresolin & Garnett 2003) agrees with the L-Z relationship derived here, but is in conflict with the L-Z relationship derived with the R_23-based oxygen abundances. The obtained L-Z relation for spirals is compared to that for irregulars. Our sample of galaxies shows evidence that the slope of the O/H-M_B relationship for spirals is slightly more shallow than that for irregulars. The effective oxygen yields were estimated for spiral and irregular galaxies. The effective oxygen yield increases with increasing luminosity from M_B=-11 to M_B=-18 (or with increasing rotation velocity from Vrot=10 km/s to Vrot=100 km/s) and then remains approximately constant. Irregular galaxies from our sample have effective oxygen yields lowered by a factor of 3 at maximum, i.e. irregular galaxies usually keep at least 1/3 of the oxygen they manufactured during their evolution.Comment: Accepted for publication in Astronomy and Astrophysics (Figures 2-5, Tables 2,6 and Appendix will only be published in the electronic version of the Journal

    The role of motivation to learn in management education

    No full text
    Employee counselling todayAs they seek to develop a culture of “lifelong learning”, many UK companies are providing “in-house” education and training for their employees. Some programmes make use of the techniques of “work-based” learning to achieve greater synergy between work roles and an academic curriculum. This paper examines the possibility that the main motivational factors for manager participants to undertake and complete one such programme are not necessarily conducive to the most effective forms of learning. It reviews some of the literature focusing upon the motivation and learning styles of mature students, and uses this as a basis for examination of data from questionnaires and semi-structured interviews with participants administered as part of a longitudinal research programme. Questions are raised about the suitability of the workplace as a site for successful academic learning and the value of such programmes to assist companies to become “learning organisations”

    An in-house business studies degree program for managers in the British automotive industry had 18 initial participants. Although achievement was high, there were concerns that participants did not recognize the value of work-based learning for fostering independent judgment and critical self-awareness

    'What's that got to do with making motor cars?' : the influence of corporate culture on 'in-company' degree programmes

    No full text
    Interest in the development of the 'learning' organisation and 'lifelong learning' has paralleled renewed concern in what, where and how industrial managers learn. 'In-company' delivery is becoming more common, as is the use of overtly vocational delivery techniques using 'work-based' learning. Delivery of education in-company, using workbased exemplars, whilst offering many benefits, has concomitant risks. Particularly in hierarchical manufacturing organisations with traditional approaches to problem solving, a powerful culture may act to inhibit the educational process, and limit the development of those very capabilities needed in the learning organisation. The recent experience of in-company education of a group of managers from a major UK motor manufacturer is discussed. The difficulties participants faced as students are examined in the light of the prevailing corporate culture, and ways are suggested for minimising these difficulties

    The well‐being of the UK Academy, 1998–2004.

    This paper compares the findings of two studies, conducted in 1998 and 2004, of academic staff in British universities. It examines the stability over time of working hours, specific work stressors and levels of psychological distress. Comparisons are also made between the levels of psychological distress currently reported by academic staff and those reported by other professional groups and the general population in the UK. Finally, the paper assesses the extent to which UK universities are meeting minimum health and safety at work standards for the management of job stressors. The findings indicate that: there has been little change in the levels of most stressors experienced over the six year period; the high levels of psychological distress found in the 1998 study are undiminished and exceed those of other professional groups and the population generally; the majority of the health and safety at work standards are not met. Possible implications of these findings for the quality of UK higher education are discussed
