Examining green production and its role within the competitive strategy of manufacturers
No full textPurpose: This paper reviews current literature and contributes a set of findings that capture the current state-of-the-art of the topic of green production.
Design/methodology/approach: A literature review to capture, classify and summarize the main body of knowledge on green production and, translate this into a form that is readily accessible to researchers and practitioners in the more mainstream operations management community.
Findings: The existing knowledge base is somewhat fragmented. This is a relatively unexplored topic within mainstream operations management research and one which could provide rich opportunities for further exploration.
Originality/value: This paper sets out to review current literature, from a more conventional production operations perspective, and contributes a set of findings that capture the current state-of-the-art of this topic
The variation of large-magnitude volcanic ash cloud formation with source latitude
No full textVery large magnitudes of explosive volcanic eruptions can produce giant ash clouds with diameters of hundreds to thousands of kilometers. These ash clouds are controlled by gravity and rotational forces, leading to a more radially constrained shape than clouds produced by smaller eruptions. Here we develop a dynamic model of the formation of large ash clouds that are produced by eruptions of constant intensity and finite duration, incorporating source latitude, eruption type, magnitude, and intensity. The cloud grows as a stratified intrusion in the stratosphere to an equilibrium shape that approximates an ellipsoid of revolution, rotating anticyclonically as a solid body, at sufficient large distances from the equator. More generally, the structure of the cloud is determined by the source latitude ? s and the parameter Y s = y s(?/Nd 0)1/2, wherein y s is the distance of the source from the equator, ? is the north-south gradient of the Coriolis frequency, N is the buoyancy frequency of the stratosphere, and d 0 is the maximum cloud thickness. A steady solution for an equilibrium cloud exists if Y s lies above a boundary that ranges from ?/2 at the equator to 0 at the pole. These clouds move westward at an increasing rate with decreasing latitude. Below this boundary steady solutions appear not to exist and the nature of the breakdown of the solution at the boundary suggests that the cloud, or part of it, moves toward and across the equator. The above parameters may be expressed in terms of latitude and cloud volume, which enables the model to be applied to the ash clouds of past large-magnitude eruptions. The results suggest that the behavior of clouds formed from plinian phases with eruption magnitudes M < 6.5 (M = log10 m ? 7, wherein m is the erupted mass in kilograms) depends on source latitude and eruption intensity, whereas for M > 6.5 they could achieve interhemispheric transport from most latitudes. For clouds from co-ignimbrite sources, for M < 7.5, cross-equatorial transport is only possible for sources in the tropics, but for M > 8, it is possible from most latitudes
Identifying (territorial) tensions in the servitized value chain
No full textPurpose: To understand the tensions that servitization activities create between actors within networks.Design/methodology/approach: Interviews were conducted with manufacturers, intermediaries and customers across a range of industrial sectors.Findings: Tensions relating to two key sets of capabilities are identified: in developing or acquiring (i) operant technical expertise and (ii) operand service infrastructure. The former tension concerns whom knowledge is co-created with and where expertise resides. The latter involves a territorial investment component; firms developing strategies to acquire greater access to, or ownership of, infrastructures closer to customers. Developing and acquiring these capabilities is a strategic decision on the part of managers of servitizing firms, in order to gain recognized power and control in a particular territory. Originality/value: This paper explores how firms’ servitization activities involve value appropriation (from the rest of the network), contrasting with the narrative norm for servitization: that it creates additional value. There is a need to understand the tensions that servitization activities create within networks. Some firms may be able to improve servitization performance through co-operation rather than competition, generating co-opetitive relationships. Others may need to become much more aggressive, if they are to take a greater share of the ‘value’ from the value chain
Increased peripheral blood pro-inflammatory/cytotoxic lymphocytes in children with bronchiectasis
No full textObjective: Bronchiectasis (BE) in children is common in some communities including Indigenous children in Australia. Relatively little is known about the nature of systemic inflammation in these children, especially the contribution of specific pro-inflammatory and cytotoxic lymphocyte subsets: T-cells, natural killer (NK) cells and NKT-like cells. We have shown that these cells produce increased cytotoxic (granzyme b and perforin) and inflammatory (IFNγ and TNFα) mediators in several adult chronic lung diseases and hypothesised that similar changes would be evident in children with BE. Methods: Intracellular cytotoxic mediators perforin and granzyme b and pro-inflammatory cytokines were measured in T cell subsets, NKT-like and NK cells from blood and bronchoalveolar samples from 12 children with BE and 10 aged-matched control children using flow cytometry. Results: There was a significant increase in the percentage of CD8+ T cells and T and NKT-like subsets expressing perforin/granzyme and IFNγ and TNFα in blood in BE compared with controls. There was a further increase in the percentage of pro-inflammatory cytotoxic T cells in Indigenous compared with non-Indigenous children. There was no change in any of these mediators in BAL. Conclusions: Childhood bronchiectasis is associated with increased systemic pro-inflammatory/cytotoxic lymphocytes in the peripheral blood. Future studies need to examine the extent to which elevated levels of pro-inflammatory cytotoxic cells predict future co-morbidities.G. Hodge, J.W. Upham, A. B. Chang, K. J. Baines, S. T.
