“…The highly random flight mechanism allows individuals to explore the entire solution space as much as possible, so the population exhibits good diversity, but it also leads to poor local exploitation ability and slow convergence speed of the algorithm. Furthermore, when dealing with complex optimization problems, CS algorithm, like other evolutionary computation methods 7 , 8 , also has the problem of low search efficiency. Therefore, many scholars have conducted extensive research to enhance the convergence performance of the algorithm.…”

Cuckoo search algorithm is an efficient random search method for numerical optimization. However, it is very sensitive to the setting of the step size factor. To address this issue, a new cuckoo search algorithm based on cloud model is developed to dynamically configure the step size factor. More specifically, the idea of giving consideration to both fuzziness and randomness of cloud model is innovatively introduced into cuckoo search algorithm, and the appropriate step size factor can be determined according to the membership degree and an exponential function, so as to realize the adaptive adjustment of the control parameter. After that, simulation experiments are conducted on 25 benchmark functions with different dimensions and two chaotic time series prediction problems to comprehensively evaluate the superiority of the proposed algorithm. Numerical results demonstrate that the developed method is more competitive than the other five CS and several non-CS algorithms.

“…Recent research on IT outsourcing highlights that contractors face critical situations in their relationship with suppliers, including factors such as: process integration and information sharing (Navarro-Paule et al, 2023), business ideas and innovation from their suppliers (Effah and Adam, 2022), vendor legitimacy (Hsu et al, 2022), control the schedule risks (Lu et al, 2022), information security (Bhatti et al, 2021) and knowledge transfer in the relationship (Deng et al, 2021). Nevertheless, it is still unclear which characteristics of IT managers can be fundamental to impact Relational Governance (RG) in IT outsourcing positively.…”

“…In addition to IT resources, the human resources involved in the management of activities, whether production, provision of services, or the use of IT products, need to be strategically managed, and this evidence the support of information systems oriented towards human resources as a factor critical success to increase the competitive power of companies (L' Ecuyer et al, 2019). High-performance work systems directly affect organizational performance, confirming that investment in practices aimed at improving human resources, in terms of fostering and sustaining a climate conducive to creativity, is a measure for which this benefit over performance is noticed (Heffernan et al, 2016).…”

PurposeResearchers in the field recognize the importance of the relationship between contractor and contractee in the process of information technology (IT) outsourcing. However, little is known about the impact of the manager's profile in this process. Thus, the objective of this research was to analyze the impact of the perception of competence, autonomy and relationship of public managers on relational governance (RG), as well as, to identify the effect of perceived control in this relationship.Design/methodology/approachThis study uses a quantitative approach to investigate the impact of the behavioral characteristics of IT managers from the self-determination theory (SDT). The data were collected in Brazilian public institutions active in the areas of education, finance, statistics and technology, and the hypotheses were identified and evaluated using the technique of partial least squares structural equation modeling (PLS-SEM).FindingsThe results identified that managers' self-determination is related to the perception of control, which, consequently, impacts the RG by providing feelings of competence and autonomy capable of building a beneficial relationship with the IT provider.Practical implicationsThis study promotes the understanding that upper management needs to support the autonomy of managers to increase their levels of intrinsic motivation when managing supplier deliveries.Originality/valueThe application of SDT to the IT outsourcing context provides new insights into the mediation of perceived control by explaining the relationship between managers' expectations and motivations as an important driver for RG.
