This study examines technological capability accumulation and the Brazilian rice industry's technological trajectory. Multiple case design was chosen, with an analysis of seven firms involved in the Brazilian rice industry. The results indicate three factors: The first was the identification of technological landmarks for firms in this sector (peeling and polishing, electronic grain selection, electronic packaging, use of forklifts and palletizers, and Industry 4.0). The second is related to the fact that different firms implemented innovative activities and technologies at different speeds, originating from the sector's different technological trajectories. The third is associated with identifying activities within the Brazilian rice industry that can be generalized to other food industries. These results have implications for formulating public policies in the sector, such as creating producer support mechanisms (research and technology transfer institutions), qualification of professionals, and encouragement for economic efficiency and competition. 相似文献

The paper examines the relationship between gamification – the use of game elements in non-gaming contexts – and innovation teams’ outcomes. It builds on psychological and teamwork theories, arguing that gamification overcomes collaboration issues and generates multiple positive outcomes, particularly in coordination, alignment, engagement, and teams’ motivation. The research follows a qualitative theory-driven using a case study of an innovation project. The conceptual model built through the findings offers valuable insights about applying gamification in innovation teams, namely: i) surprising teams with such a new and playful approach reduces stress among team members; ii) rules and time constraints play a crucial role in teams’ coordination by avoiding dispersion and enhancing focused efforts. The paper provides a set of testable theoretical propositions derived from the conceptualization of gamification in the context of innovation teams. It supports innovation managers interested in measuring gamification outcomes in teams. 相似文献

Abstract This paper is organized into two main sections. The first section examines extension as an engine for innovation and reviews the numerous priorities confronting extension systems. Section two highlights the current knowledge imperative and the critical connection of extension to post-secondary higher education and training, organizational inservice training, and vocationally oriented self-directed learning. Final comments address ‘The Continuing Role of the Public Sector’, and the prospect of its role in balancing societal interests and promoting extension as an aspect of a knowledge economy. The conclusion proposes what may be agricultural extension's challenges ahead. 相似文献

Abstract Purpose: The fields of competence development and capacity development remain isolated in the scholarship of learning and innovation despite the contemporary focus on innovation systems thinking in agricultural and rural development. This article aims to address whether and how crossing the conventional boundaries of these two fields provide new directions for developing learning and innovation competence in international development. Design/methodology/approach: Using mixed methods research, this article assesses work environments for experiential learning and innovation, and investigates effective ways of enhancing core competence in agricultural research, education, extension and entrepreneurship. Findings: Findings suggest that while the focus on input and output indicators are relevant for technological innovation competence development, outcome indicators, such as measures of changes in cognitive, affective and psychomotor domains of learning and innovation, would better serve the purpose of developing organisational and institutional learning and innovation competence. Practical implications: This research concludes that crossing the conventional boundaries of competence development and capacity development serves as a way to renew the role of education within the innovation systems thinking. However, such an attempt to enhance human capabilities and functionings through education should integrate theory-based, competence-based and experiential learning components as a coherent whole. Originality/value: This article demonstrates the value of crossing the conventional boundaries of the two seemingly unrelated fields—competence development through education and capacity development through extension—to provide new directions to operationalise innovation systems thinking in agricultural education and extension. 相似文献

Role of Brokerage in Evolving Innovation Systems: A Case of the Fodder Innovation Project in Nigeria
Elias Madzudzo 《The Journal of Agricultural Education and Extension》2013,19(2):195-210
Abstract This paper looks at brokerage functions in a project on building innovation capacity through improved networking. Innovation capacity influences how actors respond to changes in their environments. In such dynamic environments well connected sets of actors are at an advantage in that they can combine skills to address the emerging opportunities and challenges. However, policy and cultural barriers especially in African innovation systems raise the transaction costs of networking leading to weak connectivity among actors thus poor innovation capacity. This paper uses case studies from West Africa to illustrate that actors that play brokerage functions are critical in navigating around or dismantling the barriers and thus enhance innovation capacity. This paper assumes that innovation capacity rather than innovations per se is lacking in African agriculture. The paper is a product of an action research based study of Key Partner Organizations and the coalitions of stakeholders they formed around fodder innovation themes in Nigeria. We show that brokerage negotiates innovation barriers and improve networking. The paper concludes that brokerage roles are context-specific; policies that facilitate eclectic brokerage functions are critical. This paper is shedding light on the broadened scope for actors playing boundary roles, e.g. extension organizations under more relaxed organizational and policy contexts. There are few studies on brokerage and boundary work particularly in African agriculture. This study is a grounded discussion on the brokering functions in African rural development. It uses data from similar programmes to qualify observations and conclusions from the Fodder Innovation Project (FIP) case study. 相似文献

Abstract The process of innovation-development to scaling is varied and complex. Various actors are involved in every stage of the process. In scaling the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT)-led integrated watershed management projects in India and South Asia, three drivers were identified—islanding approach, multi-layered partnership, and innovative means of knowledge sharing. Through a consortium mode of partnership, ICRISAT established ‘islands’ or models for showcasing soil and water conservation interventions and integrated these with other concerns of the farming system (crops and livestock) and socio-economic dimension (capacity building). Activities on the islands were planned and implemented by the locals and replicated in satellite watersheds. Partnerships forged through the consortium approach provided a dearth of resources such as social capital. Projects built on trust and good relationships can be sustained even when direct financial support ceases. Innovative means of knowledge sharing like the Virtual Academy for the Semi-Arid Tropics (VASAT)—ICRISAT's innovation in capacity building and information management—provided the link between rural farm households and researchers. Credible intermediaries and markets were linked to farmers by information communication technology channels and markets through an interface of information and open/distance learning methods. VASAT's multi-dimensional strategy has been an important resource for a south–south partnership. 相似文献
