Purpose: Considering current debates on ecosystem services’ effectiveness and the AIS/AKIS functioning, in this study we suggest a new, systemic way to evaluate extension systems (ESs). Using this model, we compared the effectiveness of ESs in three countries with essential differences but also characteristic similarities in their agricultural sectors: Greece, Italy and Slovenia.
Design/methodology/approach: Initially, we defined ‘extension system’ as a wide range of actors integrating resources with the aim of co-producing value (not for but with) farmers. To capture the value flow within this constellation of actors we distinguished between the notion of ‘value in production’ – i.e. the value embodied in service offerings – and the value emanating when service content is used in real settings or ‘value in use.’
Findings: Our approach revealed that, despite their structural and organizational differences, the ES in the three countries share common problems arising from a limited focus on the issue of value in use.
Practical implications: The application of a systemic approach – seeing farmers as co-creators and not as end-users of extension services – in the evaluation of ESs contributes to better understand the complexity of value flow within the system and can strengthen extension systems’ effectiveness.
Theoretical implications: The present study, by reconsidering traditional evaluation approaches and by focusing on value co-production, offers an alternative value-centric framework for the conceptualization of extension services and points out to the need for refining the evaluation criteria of ESs.
Originality/value: Our work, by emphasizing the reciprocal creation of value within ESs, and by adding the concept of value in use, offers a new systems approach worth considering when evaluating ESs within different organizational and sociocultural contexts. 相似文献
Most model fit analyses in cognitive diagnosis assume that a Q matrix is correct after it has been constructed, without verifying its appropriateness. Consequently, any model misfit attributable to the Q matrix cannot be addressed and remedied. To address this concern, this paper proposes an empirically based method of validating a Q matrix used in conjunction with the DINA model. The proposed method can be implemented with other considerations such as substantive information about the items, or expert knowledge about the domain, to produce a more integrative framework of Q‐matrix validation. The paper presents the theoretical foundation for the proposed method, develops an algorithm for its practical implementation, and provides real and simulated data applications to examine its viability. Relevant issues regarding the implementation of the method are discussed. 相似文献
In response to rising consumption effects on the environment, green advertisers have employed different tactics to advertise their unique products. Limited research has explored the impact of culturally congruent appeals in green advertising. A total of 118 (N) adults participated online to assess the influence of these appeals in a cross-cultural context. Findings indicate that collectivistic appeals worked best among Indian consumers while individualistic appeals were more effective for Americans. Ad novelty and environmental concern were important covariates. Implications for advertisers are discussed. 相似文献
An important issue in the development and implementation of technology education curricula in Victoria is the extent to which
environmental and societal issues related to technology are being addressed in the teaching of technology studies. This paper
reports on the preliminary phases of a study which is intended to evaluate these aspects of technology education and describes
the development of an instrument for use with practising year 11 and 12 technology studies teachers. The instrument sets out
to measure teachers' attitudes towards (1) environmental and societal issues and (2) whether such issues should be taught
within technology studies, as well as to investigate the extent to which such issues are actually taught in practice. In order
to develop the initial version of the instrument, twenty practising technology studies teachers in Victoria were interviewed
in order to ascertain their ideas about environmental and societal issues as well as to gather some initial data on the major
questions. 相似文献
While think tanks are a global phenomenon, their role in shaping US policy offers an instructive example of think tank influence on policymaking due to the immensity of resources directed towards those ends, with education policy serving as a prime example. Focusing on a distinct set of “incentivist” education policies, this analysis describes the think tank-philanthropy linkage in US education policymaking. We offer examples of how philanthropists provide financial, empirical and political resources to advance think tanks’ policy ideas through advocacy networks; describe the multiple functions performed through advocacy networks of intermediary organisations, noting the diffusion of form and function around tasks such as knowledge production, political and media support; and we highlight the ways in which US venture philanthropists and think tanks connect around “idea orchestration” in order to advance ideas in policy processes. We suggest that, especially in the realm of incentivist policies, think tanks do not appear to produce or incubate but rather promote ideas, and actually often only a single idea. The concluding discussion considers advantages evident in idea orchestration and the implications of private control of public policymaking. 相似文献
