A network consisting of two populations of phase oscillators with heterogeneous intra- and inter-population couplings is known to be the simplest model for a chimera state. In this work, we ...generalize this chimera model by adding the indirect interaction through an external environment in the coupling scheme. The dynamical external environment is driven by the contributions from all oscillators in both populations and then it acts as a controller on the two-population chimera system. We show that a variety of symmetry-broken states including the chimera could emerge as a unique attractor due to the indirect interaction via an environment. Moreover, different states, ranging from the incoherence to the uniform drift, non-uniform drift, chimera and coherent states, can effectively be switched by adjusting the indirect coupling strength. We report on exotic behaviors such as the so-called inclined coherence, which corresponds to an intermediate state between the coherent and π-coherent states, as well as the cluster-coherent and alternating drift states as new types of symmetry breakings. To explain the mechanisms under these phase transitions between different collective behaviors, we reduce our model in the continuum limit to a low-dimensional system by applying the Ott–Antonsen approach and present stability diagrams on the basis of analyzing the reduced system. It is demonstrated numerically that the self-emerging chimera states persist for the small-size systems as well.
•Two-population chimera model is generalized by adding an indirect interaction.•Different symmetry-broken states could emerge as a unique attractor.•Inclined coherent, cluster-coherent and alternating drift states are newly reported.
Modern business conditions are determined by uncertainty, rapid change and business in a dynamic and turbulent business environment. It is clear that the environment has an impact on the business of ...the enterprise, but the enterprise also has some influence on the environment. In this context, it is very important to conduct a strategic analysis of the environment that we divide into internal and external. External environment analysis refers to the analysis of opportunities and threats, while the internal analysis focuses on the analysis of the strengths and weaknesses of the company. In this paper the emphasis is placed on the most significant methods for strategic analysis of the businesses most commonly used in practice. By applying these methods, businesses come up with important environmental information that they need when formulating a business strategy. Adequate strategic analysis of the environment is the basis for successful business and survival of a company in the market
The Greek fishing sector faces various challenges which can threaten its long-term sustainability. The PESTLE analysis is used to assess the impact of the external environment on the Greek fishing ...sector. According to our analysis, appropriate strategic planning should emphasize promoting the integration of innovation and technology transfer from the laboratory to the fisheries sector to address the challenges and capitalize on the opportunities. Future research can be conducted on the prioritization of external factors by sector experts and the coupling with other strategic planning tools.
Knowledge transfer, assimilation, transformation and exploitation significantly impact performing business activities, developing innovations and moving forward to new business models such as ...transferring to a circular economy. However, organizations’ decisions or willingness to transition to a circular economy are very often also influenced by the external environment. The study aims to determine the influence of the external environment on the transfer from a linear to a circular economy while mediating knowledge assimilation. The quantitative research involved 159 Nordic capital companies operating in Estonia and Lithuania. The survey has been performed by means of the CATI method. The analysis has been done also by applying structural equation modelling (SEM). In order to perform mediation analysis, IBM SPSS and a special PROCESS macro have been used. The study showed that knowledge assimilation partially mediates the relationship between the external environment and the transfer to the circular economy. Hence, the external environment’s direct effect is much more significant than the indirect. The added value of the study also consists in extending the concept of circular economy by including some aspects of absorptive capacity and the external environment.
Microplot experiments were conducted to evaluate the effects of cover crops on population reduction of a major soybean pest, soybean cyst nematode (SCN;
Ichinohe) in 2016 and 2017. Ten crop species, ...including annual ryegrass (
L.), Austrian winter pea (
L. subsp.
), carinata (
A. Braun), faba bean (
Roth), foxtail millet (
(L.) P. Beauvois), daikon radish (
L.), red clover (
L.), sweetclover (
L.), turnip (
subsp.
L.), and winter rye (
L.), were planted along with susceptible soybean (
(L.) Merr. 'Barnes') in soil naturally infested with each of two SCN populations (SCN103 and SCN2W) from two North Dakota soybean fields. Crops were grown in large plastic pots for 75 days in an outdoor environment (microplot). Soil samples were collected from each pot for nematode extraction and SCN eggs were counted to determine the final SCN egg density. The population reduction was determined for each crop and nonplanted natural soil (fallow). All of the tested crops and nonplanted natural soil had significantly (
< 0.0001) lower final population densities compared with susceptible soybean (Barnes). Also, a significant difference (
< 0.0001) was observed between the SCN population suppressions caused by cover crops versus the fallow treatment. All cover crops except Austrian winter pea, carinata, faba bean, and foxtail millet had consistently lower SCN egg numbers than in fallow in both years of the experiments. The average population reductions of SCN by the cover crops ranged from 44 to 67% in comparison with the initial population density, while the fallow had natural reductions from 4 to 24%. Annual ryegrass and daikon radish reduced SCN egg numbers to a greater extent than the other cover crops, with an average of 65 and 67% reduction of initial population density, respectively, from 2 years. The results suggested that cover crops reduced the SCN populations in external microplot conditions, and their use has great potential for improving SCN management in infested fields.
