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

This article examines the practice of studying texts in secondary school English lessons as a particular type of reading experience. Through a critical stylistic analysis of a popular edition of John Steinbeck’s Of Mice and Men, the article explores how reading the text is framed by educational editions, and how this might present the purpose of studying fiction to students. The article draws on two cognitive linguistic concepts – figure/ground configuration and narrative schemas – in order to explore how ‘discourse about a text’ can potentially influence how students read and engage with a text. Building on a previous article, the notion of pre-figuring is developed to offer an account of how a reader’s attention can be directed to particular elements of a text, thus privileging some interpretations and downplaying others. The article then reflects more widely on the perceived purposes of studying fiction with young people, exploring in particular the recent rise of support within the profession in England for Hirsch’s ‘cultural literacy’ model, which sees knowledge about texts as more valuable than authentic reading and personal response. 相似文献

Keith Haring painted large outdoor murals in Melbourne, Australia, in 1984 (the Collingwood Mural) and at Pisa in Italy in 1989 (Tuttomondo). Recently, both murals have been analyzed and conserved by similar teams of conservators and scientists. The original appearance of the Collingwood Mural was severely compromised, and the original materials much degraded. Tuttomondo was somewhat altered visually but with less physical damage. There were initial suggestions to repaint Tuttomondo but these were dissipated by good communication of the analytical findings. In Melbourne, there was a high-profile and emotive campaign to have the Collingwood Mural repainted. Conservators and government were heavily criticized for supposedly ignoring the artist's wishes. However, detailed research into Haring's published statements revealed that conservation does respect his artistic aims. For the Collingwood Mural, conservators had to consider whether to reduce the visual disturbances which obscured the works. Practices documented by conservation theorists and routinely undertaken by conservators guided the decision to apply mechanically reversible re-integration. This made Haring's unique ‘line’ visible and accessible again, and pleased the public. The controversies showed how conservators must communicate clearly and tactfully; appreciate the feelings of the public and involve communities in conservation, without compromising rigorous scientific and curatorial research. 相似文献

We have performed a study on the thermo-formation process of plastic shells of boots for winter sports. The aim of the work has been to determine how the process parameters can improve the ergonomic and thermal comfort for athletes and winter sports participants. We have found that the initial deformation and memory effect are strongly influenced by the type of thermoplastic material used, heating time and cooling procedure. We have also found that the ovens currently used for this process are not correctly designed to obtain an efficient heat transfer and, therefore, a heating time of at least 12 min is necessary to achieve an average deformation of more than 2 mm. The measure of the boot flexural stiffness has shown that there are no changes in the load–deflection behavior after the thermo-formation process of a ski boot made of thermoplastic polyurethane. We have also found that the thermo-formation process decreases the pressure on skier’s feet of more than five times and, therefore, improves the comfort of the skier. 相似文献

This article explores reading in the English classroom through a cognitive linguistic lens. In particular, we consider how students' ability to engage with a text, which we term authentic reading, can be facilitated or restricted. We draw on two case studies featuring Year 7 students working with the novel Holes (Sachar 2000), and the short story ‘The man who shouted Teresa' (Calvino 1996) respectively, and argue for the benefits of using cognitive linguistics as a tool for teachers and researchers to ‘think with’ when considering reading in the classroom. 相似文献

AbstractPurpose: The aim of the paper is to analyse the attitude of Italian farms in gaining access to agricultural extension services (AES).Design/methodology/approach: The ways Italian farms use AES are described through the AKAP (Awareness, Knowledge, Adoption, Product) sequence. This article investigated the AKAP sequence by submitting a questionnaire to a sample of Italian farms, providing questions on each step of the sequence.Findings: The results confirm the validity of the model and the necessity to evaluate AES in each phase of the sequence, through an in-depth analysis of the possible motivation for not adopting them.Practical implications: The functional repositioning of agriculture redefines the role of the farm, by introducing new possibilities of production and by fostering multifunctional activities. In this context, new tasks for AES emerge, aiming at sustaining farm development along either sectorial or territorial paths. Difficulties in adopting AES call for both fostering higher levels of access to services on behalf of farms and the adequate supply of services to farms' new needs.Originality/value: AKAP models have been prevailingly used in developing countries to evaluate the efficacy of extension in increasing agricultural productivity. This article demonstrates how this model could be of help in developed agriculture too in performing new lines of development rooted in the new models of multifunctional agriculture. 相似文献

Neil Gaiman’s The Graveyard Book (2009) charts the story of Nobody Owens, a boy who is adopted by supernatural entities in the local graveyard after his family is murdered. This article draws on the notion of the “construed reader,” and combines two cognitive stylistic frameworks to analyse the opening section of the novel. In doing so, the article explores the representation and significance of the family home in relation to what follows in the narrative. The analysis largely draws on Text World Theory (Werth, 1999; Gavins, 2007), but also integrates some aspects of Cognitive Grammar (Langacker, 2008), which allows for a more nuanced discussion of textual features. The article pays particular attention to the way Gaiman frames his narrative and positions his reader to view the fictional events from a distinctive vantage point and subsequently demonstrates that a stylistic analysis of children’s literature can lay bare how such writing is designed with a young readership in mind. 相似文献

Brain–computer interfacing technologies are used as assistive technologies for patients as well as healthy subjects to control devices solely by brain activity. Yet the risks associated with the misuse of these technologies remain largely unexplored. Recent findings have shown that BCIs are potentially vulnerable to cybercriminality. This opens the prospect of “neurocrime”: extending the range of computer-crime to neural devices. This paper explores a type of neurocrime that we call brain-hacking as it aims at the illicit access to and manipulation of neural information and computation. As neural computation underlies cognition, behavior and our self-determination as persons, a careful analysis of the emerging risks of malicious brain-hacking is paramount, and ethical safeguards against these risks should be considered early in design and regulation. This contribution is aimed at raising awareness of the emerging risk of malicious brain-hacking and takes a first step in developing an ethical and legal reflection on those risks. 相似文献

Precision and reliability of timescales are of importance in many situations, in particular in satellite navigation systems (i.e., Galileo system). Motivated by the necessity to improve the precision and the reliability of such clock signals, we have explored the possibility to exploit control theory in clock steering methods. First of all we provide a more robust theoretical framework for the analysis of the process. Two novel control algorithms are here proposed aiming to meet metrological specifications. Numerical simulations have been performed in order to evaluate the performances of the new control systems. 相似文献

Karate is a martial art that partly depends on subjective scoring of complex movements. Principal component analysis (PCA)-based methods can identify the fundamental synergies (principal movements) of motor system, providing a quantitative global analysis of technique. In this study, we aimed at describing the fundamental multi-joint synergies of a karate performance, under the hypothesis that the latter are skilldependent; estimate karateka’s experience level, expressed as years of practice. A motion capture system recorded traditional karate techniques of 10 professional and amateur karateka. At any time point, the 3D-coordinates of body markers produced posture vectors that were normalised, concatenated from all karateka and submitted to a first PCA. Five principal movements described both gross movement synergies and individual differences. A second PCA followed by linear regression estimated the years of practice using principal movements (eigenpostures and weighting curves) and centre of mass kinematics (error: 3.71 years; R2 = 0.91, P ? 0.001). Principal movements and eigenpostures varied among different karateka and as functions of experience. This approach provides a framework to develop visual tools for the analysis of motor synergies in karate, allowing to detect the multi-joint motor patterns that should be restored after an injury, or to be specifically trained to increase performance. 相似文献
