Purpose: This paper reflects upon the practice of Argentine rural extensionists working in the extension public system through the process of identifying different rural extensionists' types of mindsets and comparing them with transfer of technology extension approach, dialogical processes of horizontal knowledge exchange, participatory perspectives and innovation system approach.

Design/Methodology/approach: A quali-quantitative investigation was conducted. Surveys containing closed and open questions were sent via email to rural extensionists. This allowed the researcher to identify their beliefs about different issues connected to extension practice. The sample was incidental (n = 219; 143 men, 76 women). Qualitative data was categorized and quantified. Finally, a two-steps cluster analysis was implemented.

Findings: Two types of rural extensionists' mindsets were identified, one of which relates to the transfer of technology approach and other to the dialogical/horizontal model, yet neither of them fitting the ideal of the most important extension institution of the country, which supports an innovation system approach.

Practical implications: Extensionists' practices and institutional ideals do not coincide. Reflexive training processes are required to make beliefs about rural extension explicit in order to build a contextually suitable extension proposal. Originality/Value: Through a quali-quantitative approach to the issue of rural extensionists' mindsets, this paper contributes to a better understanding of Argentine rural extensionists' practices.  相似文献

The essay explores the ways that the North American Soccer Leagues (NASL) attempted to frame footballing stars in terms that North American fans would understand and embrace. The impetus for this approach was economic and influenced by the success of Pelé. However, the essay argues that the approach was deeply flawed and missed the obvious challenge of replacing Pelé – that he was irreplaceable. Nevertheless, the NASL and its boosters sought to position several stars as the natural successors to Pelé, including Franz Beckenbauer, George Best and Johan Curyff. The essay thus explores how these NASL stars were framed and how these frames would ultimately become limited.  相似文献

In order to read fluently, children have to form orthographic representations. Despite numerous investigations, there is no clear answer to the question of the number of times they need to read a word to form an orthographic representation. We used length effect on reading times as a measure, because there are large differences between long and short words for unknown words, differences that disappear when reading frequent words. Two lists of new words (half short and half long) were presented to 102 second‐grade to sixth‐grade Spanish children, to be read aloud six times. One of the lists was presented as part of a story and the other in isolation. Comparison of the length effect at the first and sixth exposure showed large differences between short and long words in the first presentation and small differences at the sixth presentation, indicating that Spanish children develop representations of words after just a few repetitions.  相似文献

Battles for technological dominance: an integrative framework   总被引:3,自引:0,他引:3  
This paper proposes an integrative framework for understanding the process by which a technology achieves dominance when “battling” against other technological designs. We focus on describing the different stages of a dominance battle and propose five battle milestones that in turn define five key phases in the process. We review the literature from several disciplines to identify the key firm- and environment-level factors that affect the outcome of a technology battle and posit that the relative importance of each factor will vary depending on the phase considered. Our framework complements and extends existing literature and has implications both for theory and for management practice.  相似文献

Recent empirical findings have questioned the use of patent citations as a measure. This points to the need of validation of patent citations methodologies, which we address by testing a recent methodology for studying technological evolution, namely connectivity analysis of citation networks. We find connectivity analysis to be a valid tool to identify the reliable knowledge which opens the way to further technological evolution of a surgical prosthesis, the artificial spinal disc. We also illustrate how connectivity analysis represents how this reliable knowledge differs depending on the stage of technological evolution. The corroborated validity of connectivity analysis of patent citations may trigger a renaissance in the use of this kind of patent data.  相似文献

The core of the Senate Bill 2042 (1998) was designed to provide the guidelines needed to prepare teachers who can meet the needs of a diverse K-12 student population in California. Following the guidelines marked by this bill, faculty working in Teacher Credential Programs across California are designing activities to prepare candidates with a deep understanding of effective pedagogies applicable to a full range of students. A key component in this preparation is to provide teacher candidates with opportunities to critically read and reflect on theory and research. Understanding the importance of this component, I designed an assignment, Quadruple Entry Journals (QEJ), which asks teacher candidates to first, critically read texts on theory; secondly, to reflect and analyze those texts; thirdly, to reflect on the reflections of their classmates; and, finally, to connect these theoretical reflections with practice. In this article, I explain the pedagogy followed when implementing QEJ with teacher candidates. Their feedback showed that when theory and research are cooperatively analyzed by teacher candidates, they better understand the connection between theory and practice, thus creating a deep understanding of what to teach and how to teach.  相似文献
