ABSTRACT

Purpose: In this paper, the knowledge dynamics of the farmer–rural extensionist’ interface were explored from extensionists’ perspective with the aim of understanding the matchmaking processes between supply and demand of extension services at the micro-level. Design/methodology/approach: Forty semi-structured interviews were conducted with extensionists whom work in the North-Eastern, Argentine provinces. Findings: Two different, general types of knowledge dynamics were identified: one moderately diffusionist, based on a hierarchical relationship and the prioritisation of experts’ knowledge, and the other constructivist, based on horizontal processes of co-construction. Interestingly, some extensionists support beliefs pertaining to both approaches. They also highlight the importance of unceremonious trainings, interpersonal trust and making recommendations that take into account farmers’ rationale. Practical implications: Results show the persistence of diffusionist rural extension and that extensionists have different, even contradictory, extension approaches, which renders inappropriate any attempt to generalise their perspectives. Theoretical implications: This study suggests that farmers’ demand is the result of a constructive, interactive process, and thus is not prior to the interaction between the demand side (farmers) and the supply side (extensionists). Consequently, the knowledge and power dynamics that take place within the farmer–extensionist interface should be considered the nucleus of demand construction and the matchmaking process. Originality/value: This paper addresses the dynamic matchmaking process between supply and demand of extension services at the micro-level, suggesting it is a constructive process and showing the core role played by power dynamics.  相似文献

This research presents the way in which children from a Nahua indigenous community build representations of the Earth’s shape, as well as the process that causes day and night. Concepts from school and local culture were studied. For the first case, a questionnaire was applied to 331 children, out of which 38 children were then interviewed on the topics from the questionnaire. For the cultural ideas, three teachers from the region and 30 children from the sample were interviewed. The results show that the representations depend on the form of questioning and the existence of three models: a flat structure with a celestial dome and mechanisms that hide or remove the Sun or the Moon in order to create day and night; a spherical structure with a surrounding sky, where the Sun and Moon rise and set; and a transitional model with a hollow sphere, flat surface and celestial dome. Cultural ideas do not appear to have any influence over these models, probably due to a loss of the community’s cosmogonic knowledge and the age of the children.  相似文献

Although counselor educators may be called on to justify publication venues, authorship order, and types of articles for purposes of promotion and tenure, there are few sources of data regarding norms for publication in counselor education. The current study examined peer‐reviewed publication venues, article types, and authorship order of 317 faculty members who were employed by 49 doctoral programs in counselor education accredited by the Council for Accreditation of Counseling and Related Educational Programs. The study reviewed 1,547 articles published between January 1997 and December 2006. Results are presented, and implications for counselor education are discussed.  相似文献

Abstract

The aim of this article is to contribute to a better conceptual and practical delimitation of inclusive education. A pedagogy that reacts to the need to face the dilemmas of difference. An interpretive and critical methodology with a documentary basis and a normative-pedagogical perspective is used. The results show a tension between theoretical approaches and the practical achievements of inclusive education. The article concludes by considering the position that if the most basic definition of education is essentially inherently inclusive, as it aims to foster the maximum development of everyone, then for the same reason it must also essentially be differentiating. This is precisely because the limits of inclusive education are in recognising and promoting excellence in difference, while the limits of differentiated education lie in recognising and promoting inclusion.  相似文献

Resumen

En este artículo se estudia el concepto de egocentrismo espacial en una muestra de 47 niños entre 4 y 13 años, a través de un diseño transversal. Los resultados demuestran que los niños tienen capacidad de ponerse en el punto de vista del observador desde el período preescolar. Por otra parte, la capacidad de construir otras perspectivas con varios objetos, teniendo en cuenta las relaciones entre ellos, comienza a desarrollarse a partir de los 6 años en estrecha relación con la edad y el nivel de desarrollo.  相似文献

College-bound recipients of DACA—a 2012?US administrative policy officially titled Consideration for Deferred Action for Childhood Arrivals—face a series of administrative and financial barriers in pursuing postsecondary education. These barriers often include a complicated process for in-state tuition consideration, as well as exclusion from the majority of educational subsidies. This research sheds new light on DACA students’ own understanding of their financial exclusions and the often ingenious methods they use to finance higher education. The research employs critical race theory/LatCrit frameworks to examine the structural systems of exclusion within educational policies and the corresponding measures taken by DACA recipient students in Ohio to overcome them. Participants’ testimonios highlight their own resilience in the face of multiple obstacles, dispel notions of meritocracy in higher education, and educate institutional agents about funding inequities in an effort to rectify them. This work finds, in response to the barriers they face, many DACA recipients in Ohio find a variety of unconventional ways to navigate a complex admissions process and secure a means of paying entirely out of pocket for their tuition. Participants in this longitudinal, qualitative research refer to these navigational strategies as participating in “the scheme game.” The scheme game consists of 3 overlapping practices: “grindin’,” “hustlin’,” and “schemin’.” Rooted in hip-hop, these terms originally refer to the ways Black, Brown, and immigrant communities navigate the barriers of a formal economy and participate in an informal economy to financially sustain themselves. Additionally, the research introduces the scheme game as a new epistemological perspective from which to understand the measures some DACA students take to afford a higher education.  相似文献

This article concerns the study of the impact of media consumption on happiness in Spain using data from the fourth wave of the European Social Survey, distinguishing between watching TV, listening to the radio, reading newspapers, and using the Internet. A negative effect of TV watching was found on individual happiness, mainly among women; those with higher incomes; and those with paying jobs—that is, among those with a higher opportunity cost of time. However, this negative effect on happiness does not appear for radio listening, newspaper reading, or Internet usage.  相似文献

The non-Newtonian properties of blood are of great importance since they are closely related with incident cardiovascular diseases. A good understanding of the hemodynamics through the main vessels of the human circulatory system is thus fundamental in the detection and especially in the treatment of these diseases. Very often such studies take place in vitro for convenience and better flow control and these generally require blood analogue solutions that not only adequately mimic the viscoelastic properties of blood but also minimize undesirable optical distortions arising from vessel curvature that could interfere in flow visualizations or particle image velocimetry measurements. In this work, we present the viscoelastic moduli of whole human blood obtained by means of passive microrheology experiments. These results and existing shear and extensional rheological data for whole human blood in the literature enabled us to develop solutions with rheological behavior analogous to real whole blood and with a refractive index suited for PDMS (polydymethylsiloxane) micro- and milli-channels. In addition, these blood analogues can be modified in order to obtain a larger range of refractive indices from 1.38 to 1.43 to match the refractive index of several materials other than PDMS.  相似文献
