Many methods must be applied in the same research project or research model.Originality/value – The paper illustrates what critical innovation factors hinder/promote innovation activity in the individual company.

Analytical approximate solution of a SIR epidemic model with constant vaccination strategy by homotopy perturbation method

Abstract: Purpose – The purpose of this paper is to introduce an efficient method for solving susceptible‐infected‐removed (SIR) epidemic model. A SIR model that monitors the temporal dynamics of a childhood disease in the presence of preventive vaccine. The qualitative analysis reveals the vaccination reproductive number for disease control and eradication. It introduces homotopy perturbation method (HPM) to overcome these problems.Design/methodology/approach – The paper considers HPM to solve differential system which describes SIR epidemic model. The essential idea of this method is to introduce a homotopy parameter, say p, which takes values from 0 to 1. When p=0, the system of equations usually reduces to a sufficiently simplified form, which normally admits a rather simple solution. As p is gradually increased to 1, the system goes through a sequence of deformations, the solution for each of which is close to that at the previous stage of deformation. One of the most remarkable features of the HPM is that usu...

Migrating personality theories Part 2: towards a theory of the balanced personality?

Abstract: Purpose – Some personality schemas are seen to compete with others, but are they really complementary? The purpose of this paper is to show that two trait approaches, Myers‐Briggs Type Indicator (MBTI) and Mindscape theory, which are normally considered to be competitive, shall be migrated into a more complex modeling space using knowledge cybernetics, when they are shown to have a complementary potential.Design/methodology/approach – The paper uses the meta‐framework of knowledge cybernetics (KC) part of the relevantial universe identified by Maruyama, to migrate different theoretical approaches and relate them. A consequence is the possible development of a more sophisticated trait theory that is capable of providing more complex information about personality.Findings – The findings indicate that current type theories are not necessarily stand‐alone, but may be seen as complementary within a broader conceptual framework.Research limitations/implications – This paper is limited to the investigation of MB...

Weak signal detection method based on Duffing oscillator

Abstract: Purpose – The purpose of this paper is to detect the periodic signal under strong noise background, and estimate its amplitude/phase.Design/methodology/approach – Melnikov method is adopted as calculating the threshold value when chaos occurs, and the detected signal is taken as a system parameter. The system's output state is changed if the parameter has a slight change near the threshold. Meantime, the phase of system's output is recognized to judge whether the output state changes, and the signal parameter is estimated according to the necessary condition.Findings – A small periodic signal in noise can be detected by Duffing oscillator via a transition from chaotic motion to periodic motion.Research limitations/implications – The paper shows how to calculate the amplitude/phase in low signal‐to‐noise ratios.Practical implications – The Duffing system is sensitive to the weak periodic signal and has definite immunity to noise, so it is easy to construct a system composed of many oscillators that could p...

Migrating personality theories Part 1: creating agentic trait psychology?

Abstract: Purpose – Pluralities of personality schemas reside across different Maruyama universes suggesting incommensurability and isolation. Schemas may migrate across Maruyama universes given appropriate means. As illustration, the Myers Briggs Type Indicator (MBTI) schema for personality temperament is migrated into a sociocognitive schema through the intermediary of knowledge cybernetics (KC). MBTI is a type approach that operates with polar opposites; however, conceptually there is no reason for it not to be associated with a trait space. Supposing that MBTI has traits at some horizon of meaning, then since traits are responsible for the creation of enduring states, sociocognitive explanations should be able to explain the stable states consistent with a variation of the McCrae and Costa proposition. As a result this paper aims to formulate for the first time a link between the MBTI type schema, a trait space, and a capacity for sociocultural descriptions.Design/methodology/approach – The paper uses the meta‐...

Toward a holistical perception of the content of business ethics

Abstract: Purpose – The purpose of this paper is to offer a new requisitely holistic definition of business ethics (BE) as a crucial component of business cybernetics and practice. The present contribution considers a basic problem: how humans use BE to influence their business processes. Therefore, business is/should be investigated from the viewpoint of ethics. Requisite holism of understanding and consideration of BE in business reality is unavoidable; it can (and must) result from findings and considerations of the interdependence between business practice, ethics, and BE.Design/methodology/approach – In this paper, qualitative analysis is applied on the basis of the cybernetics (e.g. especially business cybernetics), dialectical systems theory, and ethics theory.Findings – Ethics is a crucial emotional part of human attributes. They can be viewed as the subjective part of the starting points of any human acting/behavior process, including business. Thus, ethics (may) have/has a crucial role in business cyberne...

Success factors and competencies in organisational evolution

Abstract: Purpose – The purpose of this paper is to investigate organisational evolution and change forces that influence the adaptation process. Despite significant research interest in this topic, the knowledge is still incomplete.Design/methodology/approach – The paper examines the importance of organisational evolution and introduces two frameworks, five change forces and success factors and competencies, in the process of transformation from the new economy to the innovative economy.Findings – The paper finds that organisational capacity for transformation in response to the economic change forces has become the critical success factor in the ever‐changing business environment where more competition means more intense selection. As organisations fight to remain on the market, unadaptive and consequently unsuccessful rivals fail to capture an adequate market share and have to exit.Research limitations/implications – It would be particularly interesting to conduct studies in different countries to see whether th...

China's population projections based on GM(1,1) metabolic model

Abstract: Purpose – The purpose of this paper is to apply grey system theory to population system and project China's population.Design/methodology/approach – The paper applies the GM(1,1) model to China's population projections. Two key aspects of the method are crucial for obtaining best accuracy of prediction. They are the choice of the length for the original data to be used in the model and the adoption of the GM(1,1) metabolic model in prediction. The former determines what initial data to be used while the latter describes an iteration process on how to proceed to predict.Findings – The results show that in 2015 China's population will reach 1.37 billion and in 2050 it will be between 1.42 and 1.48 billion, which is in accordance with the latest projections from the UN. The findings show the GM(1,1) metabolic model is an effective mathematical means in population projections.Research limitations/implications – The paper suggests that GM(1,1) metabolic model can provide an effective simulation model for compl...
