The Bass model is widely used in the literature to capture the diffusion of innovations and shows excellent predictive power in the context of durable goods. However, the model's efficacy fades when services are the target of analysis. Services that users adopt and subsequently utilize regularly are regarded as a continuous process that entails the possibility of dis-adoption and re-adoption. These aspects are not accounted for in the traditional Bass model. Thus, this study extends the Bass model to information system (IS)-based services by taking into account the unique nature of service adoption: the possibility of dis-adoption and re-adoption.

The proposed hypotheses were empirically tested using a longitudinal study of mobile service usage over 18 months. The longitudinal design provides a stronger position than the typical cross-sectional survey to understand the dynamics and infer causality.

Results show that the inclusion of the dis-adoption and re-adoption rates in the Bass model significantly improves the explanatory power over the traditional Bass model.

Consumption of services delivered through IS has exponentially increased. However, understanding on the diffusion pattern of IS-based services is limited. Our study is the first to examine the effect of dis-adoption and re-adoption together in the innovation diffusion process. The study offers significant implications for researchers and practitioners. The extended Bass model can help service firms develop an accurate prediction about the number of adopters at different periods of time.

New agricultural technologies are continuously generated and promoted for adoption by farmers with the expectation that they bring about higher benefits than older technologies. Yet, depending on the perceived benefits, the user of the technology may choose to stop using it. This paper aims to analyze what drives farmers to dis-adopt climate smart sorghum varieties in Tanzania.

The study uses cross-sectional farm household level data collected in Tanzania from a sample of 767 households. The determinants of dis-adoption are explored using a bivariate probit with sample selection model.

The authors find that while farmers switch between different sorghum varieties, most farmers actually quit sorghum production. Older farmers and those facing biotic stresses such attacks by birds are more likely to dis-adopt sorghum.

These findings suggest that there is scope for improving and sustaining the adoption of sorghum varieties in Tanzania once extension services are strengthened. The findings also point to a well-founded theory on the role of markets in enhancing the overall sustainability of food systems.

The study findings have broader implications for understanding the sustainability of improved technology adoption

Dis-adoption is also positively associated with the lack of access to markets underscoring the role of markets in enhancing the overall sustainability of technology adoption and food systems.

This paper aims to explore pathways in which adaptation challenges may occur. Focus is on the barriers to adaptation, challenges to adaptation and maladaptation with reference to smallholder farmers in the Southern African Development Community region.

Bibliometric analysis techniques were used to track the literature on smallholder farmers’ adaptation challenges. Web of Science was the main data source. A total of 41 articles were retained for analysis and exported into Visualization of Similarities Viewer Software where the development of research on the subject, co-occurrence of keywords analysis, top publishers, citations and total link strength was done.

Results indicate that research on smallholder farmers’ adaptation challenges is not new but has gained more consideration post-2020. The main adaptation challenges emanate from perception barriers and constraints based on determinants of adoption, limitations for resilience building and achieving sustainable adaptation as well as contestations around Climate Smart Agriculture technologies.

Effective design of adaptation policies should center on prioritizing the needs of the local people. This would reduce the occurrences of smallholder farmers’ adaptation challenges, promote resilience building and contribute toward achieving sustainable adaptation.

It is equally important to document adaptation challenges. However, adaptation challenges are rarely shared with the same enthusiasm as its successes. This work focuses on the matter with the intention of conscientizing smallholder farmers to reduce the risk of repeating the same adaptation mistakes.

Medical disruptive innovation is essential for deepening the reform of health-care system. The theory of general disruptive innovation assumes that innovations can diffuse by benefiting and attracting consumers through observed and objective relative advantages. Yet decision-makers for adoption in health-care settings are safety-sensitive professionals whose cognitions barriers about underperformance in focal attributes will impede further evaluation of innovation's ancillary performance. Existing studies do not answer the question of how such innovations can overcome safety barriers, find early adopters and grow to the early majority. The purpose of this study is to investigate the process, mechanism, and path of early diffusion of medical disruptive innovation.

The authors conduct a longitudinal case study of the diffusion of Enhanced Recovery After Surgery (ERAS) in China during 2011–2018.

The authors find that the diffusion process of medical disruptive innovations can be viewed as a cognitive evolutionary process that sequentially establishes conformity, differentiation and normalization. Cognition reframing of expert, meaning and benefit for professionals is its implicit mechanism. When adoption may trigger cognitive concerns, actors’ very early (dis)adoption is driven by a combination of structural position, innovation attributes and performance perceptions; central actors then play amplifier roles in the development from early adopters to the early majority.

This study proposes a process theoretical framework for the early diffusion of disruptive innovation. By dissecting the key processes and mechanisms from a cognitive perspective, the study offers theoretical contributions and practical insights into the diffusion of disruptive innovation in professional settings.

This paper aims to develop a diffusion model that can be used to understand and forecast the market growth of service products in a competitive environment. Despite the fast growth of the service sector, the existing literature has dedicated little effort to modeling the market growth of service products.

The authors propose a choice-type diffusion model that links the issues of service product utility, customers’ choice preference, customer switching behavior and the market growth of service products. The authors use the market data of one online product and assess the performance of the proposed model using this case.

The results demonstrate the model’s good fitting and forecasting performance. Specifically, the proposed model has better performance than the benchmarks the authors choose from the existing literature.

This study shows that market growth of service products can have different diffusion patterns with that of durable goods, which is evidence of the needs for specific models for service diffusion. Further, this study demonstrates the important role of customer switching in service diffusion. Also for marketing practitioners, this study provides an explanation and forecasting tool for the market growth of service products, which can be used for marketing planning in the service industry.

Through the application of traditional and contemporary feminist theories in gender mainstreaming, the purpose of this paper is to contribute to emergent debate on gender dimensions in climate-smart agriculture (CSA) adoption by smallholder farmers in disaster-prone regions. This is important to ensure that CSA strategies are tailored to farmer-specific gender equality goals.

An exploratory-sequential mixed methods research design which is qualitatively biased was applied. Key informant interviews and farmer focus group discussions in two study sites formed initial qualitative phase whose findings were explored in a quantitative cross-sectional household survey.

Findings shared in this paper indicate the predominant application of traditional gender mainstreaming approaches in CSA focusing on parochial gender dichotomy. Qualitative findings highlight perceptions that western gender approaches are not fully applicable to local contexts and realities, with gender mainstreaming in CSA seemingly to fulfil donor requirements, and ignorant of the heterogeneous nature of social groups. Quantitative findings establish that married men are majority adopters and non-adopters of CSA, while dis-adopters are predominantly de jure female household heads. The latter are more likely to adopt CSA than married women whose main role in CSA is implementers of spouse’s decisions. Access to education, intra-household power relations, productive asset and land ownership are socio-cultural dynamics shaping farmer profiles.

By incorporating African feminisms and intersectionality in CSA, value of this study lies in recommending gender policy reforms incorporating local gender contexts within the African socio-cultural milieu. This paper accentuates potential benefits of innovative blend of both contemporary and classic gender mainstreaming approaches in CSA research, practice and technology development in disaster-prone regions.

Introduction: As internet and communication technologies are getting developed, the commercial transaction is becoming more electronic. This change also brings new approaches to new payment mechanisms like emergence of crypto currencies. They are virtual and digital currencies which can only be used in electronic environment but they are increasingly treated as a new payment and investment tool. Nevertheless, their use has not spread into the general public, yet. At this point, it will better to take the complex nature of the crypto currencies into consideration because it may still lead to some risks for people and the type of the risks perceived by consumers may influence their attitudes toward and intention to use crypto currencies.

Aim: Accordingly, this study attempts to examine the interaction between perceived risk, attitudes toward and intention to use crypto currencies within the context of Bitcoin, as the first crypto currency.

Method: This study was designed as a causal research. The sample of the study was reached by using convenience sampling method and data were collected with survey. The compiled data were tested with Structural Equation Model.

Findings: A statistically significant and negative relationship was found between perceived financial, time and psychological risk and attitudes toward the use of Bitcoin, and a statistically significant and positive relationship was found between attitudes toward and intention to use Bitcoin. The findings of the study are expected to contribute to both relevant literature and practice by explaining the financial behavior of the individuals within the context of perceived risk theory.

The purpose of this paper is to analyze the social institutions of trust, accountability and corporate shared value in creating an enabling environment for private sector investment in African agricultural and food systems.

This paper uses mixed methods. A value chain framework models interactions among stakeholders in the agriculture, agribusiness and food sectors. The social institutions of accountability and trust are introduced into the model, followed by a Rwanda premium coffee value chain case study.

The conceptual and case study results show that best practices can increase smallholder farmer, agricultural service provider, financial intermediary, and food processor investments in and benefits from the agriculture sector.

Further research is needed on the economic foundations of development cooperation based on trust, accountability and shared values, best practices and the link with desired societal outcomes, such as the sustainable development goals.

Mutual accountability processes, as they are maturing in Africa, are at the cutting edge of creating processes where multiple stakeholders, including agribusiness, can come together to make joint commitments to a shared development agenda, and where stakeholders hold themselves and others accountable for meeting these commitments.

This is the first paper to bring together cutting-edge advances in corporate shared values, trust and accountability in the context of African agricultural and agribusiness development.

To examine the key factors that can engender initial trust in mobile money and to also determine whether initial trust can contribute to the perceived value of mobile money, use and recommendation intentions. More specifically, this paper, based on initial trust building model, aims to identify the institutional, cognitive and socially related factors enhancing initial trust in mobile money and its relationship with perceived value, use and recommendation intentions.

A self-administered questionnaire was used to collect data from 781 research participants. Variance-based structural equation modelling was used to examine the proposed research model.

This research shows the importance of the institutional factor of structural assurance, in conjunction with perceived firm reputation and communicability, in engendering initial trust in mobile money and, in turn, enhancing perceived value, use and recommendation intentions. The research further confirms the mediating influence of perceived value in the relationships between initial trust, use and recommendation intentions.

The originality of this work lies in the development and empirical confirmation of the research model and which together contributes to an increase understanding of initial trust building in mobile money acceptance. Value-wise, this work has the potential to inform managerial and public policy interventions by helping mobile money operators and policymakers’ rollout essential and even sophisticated financial services like borrowing using the mobile phone for the financially under-served in developing and trust-deficit settings.
