TL;DR: This study investigates innovation diffusion speed, in each network topology and demonstrates that diffusion of innovative products accelerates when innovators of a virtual economic system are placed according to a random network and when amount of innovators and imitators in the economic system increases.
Abstract: Simulation modelling has gained ground over the years since it can provide various scenarios applied to any scientific area. In this study, a stochastic cellular automata model is proposed, in which agents fall into three distinct categories (adopters, non-adopters and denials). Based on Hofstede’s cultural dimension individualism, we characterize three major international markets, as perfectly clustered (collective) to perfectly random (individualistic). We investigate innovation diffusion speed, in each network topology. At each time step, the decision of non-adopters to purchase innovative products, is affected by their immediate neighborhood (von Neumman). The speed of diffusion is evaluated using time at which sales reach 50% of market. Effects of simulation parameters on speed of diffusion, are assessed using a log-normal accelerated failure time model. Results demonstrate that diffusion of innovative products accelerates when innovators of a virtual economic system are placed according to a random network and when amount of innovators and imitators in the economic system increases. Slower innovative products’ diffusion process is a result of a large amount of denials and of how imitators are placed in the in the virtual economic system. Diffusion in small-world virtual economic systems lead to small time inflexion points very close to those of a random networked market.

TL;DR: In this article, training on scaling up of water productivity in agriculture was organized and evaluated at all the stages of the Knowledge, Attitude, and Skill and Aspiration (KASA) model, where change in knowledge, attitude, skill and aspiration leads to modification in practices for creating desired changes in water management in agriculture.
Abstract: Extension functionaries play a catalytic role in adoption of agricultural innovations where water management is no exception. Training plays a pivotal role for enhancing the competence of extension functionaries’ through diffusion of innovations at actual workplace. In this stride, training on scaling up of water productivity in agriculture was organized and evaluated at all the stages of the Knowledge, Attitude, and Skill and Aspiration (KASA) model. The model assumes that change in knowledge, attitude, skill and aspiration leads to modification in practices for creating desired changes in water management in agriculture. Significant change in acquiring knowledge, developing participatory skills, changing attitudes and fulfilling aspirations towards scaling-up of water productivity in agriculture was observed. Hence, the enhanced learning will be effectively diffused among the farmers at the actual workplace for effective water management.

TL;DR: In this paper, the authors examine the process of diffusion and adoption and its associated constructs affecting athletics coaches' decision-making process surrounding the learning about and subsequent use of sport psychology.
Abstract: Since the 1980s, commonly referred to as the ‘golden era’ of sport psychology (Biddle 1989), there has been a consistent stream of evidence surrounding the usefulness and positive impact of sport psychology upon athletic performance (Zakrajsek et al 2013). However, the process and factors which impact upon the transference of such knowledge into the coaching environment has been limited. Thus, while sport psychology as an academic field is well established, its use in the applied setting is reported to be sporadic but with little understanding as to why. This thesis examines the use of Rogers’ Theory of Diffusion of Innovations within the athletics domain. Specifically, the focus is to examine the process of diffusion and adoption and its associated constructs affecting athletics coaches’ decision-making process surrounding the learning about and subsequent use of sport psychology. Consequently, the aim of the study was to critically analyse and explore the diffusion process, and factors which influence the adoption of sport psychology, thus providing a synthesis of research in the form of a conceptual framework. To achieve this, from the post-positivist standpoint, a mixed-methods multi-strand design was implemented to guide the methodological process. Phase 1 involved the undertaking of semi-structured interviews in order to establish initial insights into the understanding of coaches and the subjective reality of sport psychology in athletics coaching. Results from the representative sample of licensed athletics coaches authenticated the use of the Theory of Diffusion of Innovations as a mechanism for evaluating coaches’ decision-making surrounding the use of sport psychology. Information gathered informed the development of Phase 2 which incorporated the concurrent collection of quantitative data (strand A) and qualitative data (strand B) thus providing deeper insights into the process of diffusion and the driving forces that influence the adoption decision. 160 UK licensed athlete coaches completed the quantitative survey which was divided into five sections pertaining to each stage of the Innovation-Decision Process and additional information surrounding the driving forces affecting the process. Qualitative semi-structured interviews were undertaken with 24 participants representing the varying roles within the athletic social system. The results showed there to be two component parts to the diffusion and adoption of sport psychology. The cognitive aspect incorporated knowledge, understanding and perception development and led to a decision for or against the use of sport psychology. The behavioural aspects included implementation and confirmation of previously made decisions regarding the use of sport psychology. Each stage of the Innovation-Decision Process was found to be affected by intra and inter personal and structural barriers. Those experiences were dependent on coaches’ classification as a participation or performance coach along with their level of educational background in sport. However, barriers could be overcome by facilitating factors. The study raises both theoretical and practical implications and recommendations for facilitating an improved diffusion and adoption process.
