Knowledge integration played a major and centre role in the process of organizations knowledge innovation. Study on the knowledge integration contents and process in organization has important significance. There are four contents of knowledge integration in organization knowledge innovation: knowledge integration between different knowledge main bodies; different knowledge levels; the new and original knowledge system; personal study, team study and organization study. The paper discussed the process of knowledge integration toward organization knowledge innovation based on lify-cycle theory and divided the process into four stages: embryonic stage, development stage, mature stage and diffusion stage. The paper analyzed the knowledge value in different life cycle stages and the result indicates that the knowledge in mature stage is the most valuable.

Altered Gravity

The gravitropism of a mature stage IV Phycomyces sporangiophore has a shorter and more uniform latency if the sporangiophore is exposed horizontally to gravity during its earlier development (stage II and stage III). This early exposure to an altered gravitational orientation causes the sporangiophore to develop a gravireceptor as it matures to stage IV and resumes elongation. A technique has been developed to observe the spatial relationship between the vacuole and the protoplasm of a living sporangiophore and to show the reorganization caused by this exposure to altered gravity. Possible gravireceptor mechanisms are discussed.

Main Challenge

<p>Polar lows (PLs) are important mesoscale (horizontal diameter up to 1000 km) maritime weather systems at high latitudes, forming pole ward from the polar front. We consider the possible prognostic criteria of PLs, in particular, the kinematic helicity as a quadratic characteristic related to the integral vortex formations and the kinematic vorticity number (KVN). To calculate such characteristics we use reanalysis data and the results of numerical simulation with the WRF-ARW model (Version 4.1.) for the PLs over the Nordic (Norwegian and Barents) seas. For comparison, experimental data are used.</p><p>Our estimate of helicity is based on the connection of an integral helicity (IH) in the Ekman layer with the geostrophic wind velocity, due to the good correlation between IH and half the sum of the wind velocity squared. We have chosen IH averaged over preselected area covering the locality of PLs genesis. This area was moving along with the centre of PL during the numerical simulation.</p><p>The genesis of PLs can be divided into three stages: (i) an initial development stage, in which a number of small vortices appear in a shear zone; (ii) a late development stage, characterized by the merger of vortices; (iii) a mature stage, in which only a single PL is present. Approximately one day before PL formation, a significant increase in helicity was observed. The average helicity bulk density of large-scale motions has values of 0.3 – 0.4 ms<sup>-2</sup>. The local changes in helicity are adjacent to the front side of the PLs. The IH criterion described facilitates the identification of the PLs genesis area. For a more detailed analysis of the PL genesis, it is recommended to apply KVN, which is the additional indicator of PL size and intensity. At the moment of maximum intensity of PLs KVN can reach values of 12 – 14 units. The advantage of using KVN is also in its clear change directly in the centre of the emerging PLs, which allows to precisely indicates the limits of the most intense part of PLs.</p><p>The main challenge is to make the operational forecast of PLs possible through the selection of the prognostic integral characteristics of PLs, sufficient for PLs identification and for analysis of their size and intensity in a convenient, usable and understandable way. The criteria associated with vorticity and helicity are reflected in the PLs genesis and development quite clearly. At this time, such a claim is only a hypothesis, which must be tested using a larger set of cases. Future work will need to extend these analyses to other active PL basins. Also, it would be interesting to compare the representation of PLs by using any other criteria. It is intended to use our combined criteria as a precursor to machine learning-based PLs identification procedure where satellite image analysis and capture of particular cloud patterns are currently applied in most of the cases. It would eliminate the time consuming first stage of collecting data sets.</p><p>This work was supported by the Russian Science Foundation (project No. 19-17-00248).</p>

Distributed Technologies

Purpose This paper aims to focus on distributed technologies with the aim of highlighting their economic-organizational dimensions. In particular, the contribution first presents a deeper understanding of the nature and the dynamics of the economies and diseconomies that arise from the adoption and diffusion of distributed technologies. Second, it aims to shed light on the increasing tension between the hierarchy-based model of production and peer-to-peer (p2p) production, which involves the pervasive diffusion of distributed technologies. Design/methodology/approach Adopting an economic-organizational perspective, which is deeply rooted in the related extant literature, an analytically consistent model is developed to simultaneously take into account the following variables: adoption density independent variable) and economies of knowledge integration and organizational diseconomies (the costs of a loss of control and the costs of organizational decoupling and recoupling) as dependent variables. Findings Distributed technologies allow access to a large quantity and a wide variety of cognitive slacks that have not been possible until now. In doing so, they are leading the transition towards p2p. This is an emerging production paradigm that is characterized – with respect to mass production – by a shift in the relative importance of cognitive slack in comparison with tangible slack. Nevertheless, the unrestrainable diffusion of distributed technologies is not neutral for organizations. On the one hand, these technologies allow for the integration of economies of knowledge, and on the other hand, they involve organizational diseconomies that should not be ignored by managers and researchers. Originality/value This paper fills a gap in the literature by developing a consistent analytical framework that simultaneously takes into account the economies of knowledge integration and potential organizational diseconomies (the costs of coordination and the loss of control) that arise from the adoption and diffusion of distributed technologies.

Organizational Lifecycle

Purpose This study aims to examine the relationship between organizational lifecycle stages, the adoption of strategic management accounting (SMA) practices and the performance consequences of SMA adoption. Design/methodology/approach The analysis is based on survey data from 377 firms operating in German speaking countries. Findings The author finds that the firms’ adoption rates of SMA increase from the birth to the revival lifecycle stages and drop at the decline stage. Firms that deviate from the optimal SMA profile have lower performance compared to the firms that do not deviate. The negative performance effect, however, is only significant for firms that have too little SMA practices and is not significant for firms that adopt too much SMA practices. Research limitations/implications These results suggest that firms that fail to implement a sufficient level of SMA suitable for their development stage will not develop as fast as their competitors. This study is subject to general limitations of survey research, particularly with respect to the operationalization of the variables, the number of contextual variables in the empirical model and sample coverage. Practical implications The implication for managerial practice is that greater efforts should be directed toward eliminating underfit than overfit regarding the implementation of management control systems. Originality/value This is the first analysis of the adoption of SMA at different life cycle stages and the consequences of misfitted adoption.

Abstract A polar mesocyclone (PMC) observed over the Japan Sea on 30 December 2010 was studied using a nonhydrostatic mesoscale numerical model with a horizontal resolution of 2 km. The numerical simulation successfully reproduced the observed life cycle of the PMC. The results of the numerical simulation suggest that the life cycle of the PMC may be divided into three stages: an early development stage, in which a number of small vortices appear in a shear zone; a late development stage, which is characterized by the merger of vortices and the formation of a few larger vortices; and a mature stage, in which only a single PMC is present. During the early development stage, vortices are generated in the shear zones of strong updrafts in discrete cumulus convection cells. In contrast, during the late development stage, the vortices develop as a result of barotropic instability in the shear zone. A cloud-free eye and spiral cloud bands accompany the mature stage of a simulated PMC. A warm core structure also forms at the center of the PMC on account of adiabatic warming associated with downdrafts. The structures in the PMC during the mature stage resemble those of a tropical cyclone. Sensitivity experiments, in which sensible and latent heat fluxes from the sea surface and condensational heating were switched on/off, demonstrate that condensational heating is critical to the development of the PMC at all stages, and that sensible and latent heat fluxes play secondary roles.

Abstract The total quasigeostrophic (QG) vertical motion field is partitioned into transverse and shearwise couplets oriented parallel to, and along, the geostrophic vertical shear, respectively. The physical role played by each of these components of vertical motion in the midlatitude cyclone life cycle is then illustrated by examination of the life cycles of two recently observed cyclones. The analysis suggests that the origin and subsequent intensification of the lower-tropospheric cyclone responds predominantly to column stretching associated with the updraft portion of the shearwise QG vertical motion, which displays a single, dominant, middle-tropospheric couplet at all stages of the cyclone life cycle. The transverse QG omega, associated with the cyclones’ frontal zones, appears only after those frontal zones have been established. The absence of transverse ascent maxima and associated column stretching in the vicinity of the surface cyclone center suggests that the transverse ω plays little role in the initial development stage of the storms examined here. Near the end of the mature stage of the life cycle, however, in what appears to be a characteristic distribution, a transverse ascent maximum along the western edge of the warm frontal zone becomes superimposed with the shearwise ascent maximum that fuels continued cyclogenesis. It is suggested that use of the shearwise/transverse diagnostic approach may provide new and/or supporting insight regarding a number of synoptic processes including the development of upper-level jet/front systems and the nature of the physical distinction between type A and type B cyclogenesis events.

This paper aims to provide an insight to later researchers on the application of axiomatic design in the area of design for end-of-life (EOL) management. Among all life cycle stages of a product, design and development stage is the one that influences the later stages the most in terms of environmental impacts. In order to achieve sustainable product development, one of the considerations to be taken during the design stage is EOL management. EOL management process can be enhanced by utilizing a robust design method as well as an effective method for evaluating product design. Recent researches show that application of axiomatic design in the field of eco-design (especially design for EOL management) is still in a premature stage despite having a vast application area that covers the aspect of product design, manufacturing and supply chain management. Nonetheless, a case study published recently on eco-design using axiomatic approach has shown adequate feasibility and effectiveness. Therefore, design for sustainable EOL using axiomatic approach is worth further exploration.

Abstract. Using observations from the GPM Tropical Cyclone Overpass Dataset and Himawari-8, this study statistically analyses the tropical cyclones (above Typhoon categories) in the Northwest Pacific during the tropical cyclone (TC) frequent period (from May to October) of 2014–2018. Moreover, a case (Super Typhoon “Mangkhut”) was analysed in detail. This study uses a semi-manual method to identify three life cycle stages of tropical cyclones: developing stage, mature stage, and dissipating stage. The statistical results show that the distribution of precipitation and latent heat varies with positions and the tropical cyclone has the maximum precipitation (11.62 mm/h) at the mature stage along with the maximum convection ratio (22.97%) at the developing stage. It is most obvious that the release of latent heat in the upper cloud at developing stage and in the lower cloud at mature stage. The latent heat profile of convective precipitation presents a “bottom-heavy” structural, and the stratiform precipitation has a “top-heavy” latent heat profile. The proportion of stratiform precipitation to total precipitation (74.31%) is the largest, but the average precipitation of the stratiform (4.12 mm/h) is lower than the average precipitation of convective clouds (10.55 mm/h). The average particle radius of the stratiform precipitation is 1.13 mm, while the average precipitation particle radius of the convective cloud precipitation is 1.79 mm. Based on these statistical results, this paper briefly analyses the characteristics of cloud precipitation microphysical mechanisms in three life cycle stages. Besides, the latent heating profile distribution found in this study are related to the vertical variation of precipitation rate, which are different in terms of the type of precipitation cloud.

The major aim of this paper is to compare the explanatory power of risk measures versus performance measures in different life-cycle stages. To test the hypotheses, first, sample firms were classified into three life-cycle stages (Growth, Mature and Decline). Then, using regression models and Vuong's Z-statistic, the hypotheses were investigated. In this study, financial information of 75 firms which were accepted at Tehran’s Stock Exchange (TSE) from 2003 to 2008 (450 firm-years) was examined. The results of this study show that in growth and decline stages, the explanatory power of risk measures is significantly higher than performance measures and in mature stage, the opposite is true.
