Abstract

Purpose: Scholars agree that evaluation of participatory action research is inherently valuable; however there have been few attempts at evaluating across methods and across interventions because the perceived success of a method is affected by context, researcher skills and the aims of the participants. This paper describes the systematic evaluation of participatory action research with 17 European networks (LINSA) as part of a research project titled SOLINSA: Support of Learning and Innovation Networks for Sustainable Agriculture.

Methodology: Participatory action research was carried out over three years in collaboration with the 17 LINSA using a learning-oriented evaluation that was adapted to SOLINSA. The collaboration was evaluated using a structured evaluation instrument that was developed in the project.

Findings: The primary achievements of the interactions were based around enabling LINSA to reflect on their state and their practices. Joint reflection; facilitated by a member of the research team and in collaboration with the LINSA, stimulated internal engagement, enabled rethinking of the network's positioning, contributed to strategy development, and enabled creation of concrete outputs. Participation in the reflection process served to encourage commitment to the LINSA by individuals while improving relationships within the LINSA. Researchers and participants expressed that collaborative action research can be considered successful when both parties give and gain benefits, such as new knowledge or improved practical solutions.

Practical implications: Comparison of self-evaluation of different networks using a single tool enabled the identification of common factors that contribute to successful collaboration. Included in these common factors was the need to identify and build a working relationship with key partners based on mutual trust and commitment, and to gain a balance between guidance and listening, interactions and freedom, and positive and critical reflection: a fragile equilibrium that is difficult and time consuming to establish.

Originality: The adaptation of learning-oriented evaluation, by including a structure to allow comparison between the wide range of contexts, provides a useful instrument for evaluating participatory action research processes.  相似文献

Embalming fixatives such as formaldehyde and phenol have been associated with occupational health hazards. While anatomists aim at replacing these chemicals, this seems presently unfeasible in particular for formaldehyde. Furthermore, fixation protocols usually require well-equipped facilities with highly experienced staff to achieve good fixation results in spite of only a minimal use of formaldehyde. Combining these aspects, a technique robust enough to be carried out by morticians is presented, resulting in durable tissues with minimal formaldehyde use. An embalming protocol involving phenoxyethanol was established, using concentrations of 7 and 1.5 Vol% of phenoxyethanol in the fixative and the conservation fluid, respectively. Visual, haptic, histological, and biomechanical properties and their perceived potential to positively influence student learning outcomes were compared to standard embalming techniques. The phenoxyethanol technique provides esthetic, durable, and odorless tissues. Bleaching is less pronounced compared to ethanol- or formaldehyde-based protocols. The tissues remain pliable following the phenoxyethanol-based embalming and can be used for biomechanical experiments to some extent. Phenoxyethanol-fixed tissues are well suited for undergraduate teaching with perceived positive learning outcomes and partly for postgraduate training. Phenoxyethanol tissues provide the option to obtain well-preserved histology samples, similar to those derived from formaldehyde. The provided protocol helps replace the use of phenol and formaldehyde for conservation purposes and minimizes the use of formaldehyde for the initial injection fixation. Phenoxyethanol-based embalming forms an effective alternative to standard embalming techniques for human cadavers. It is simple to use, allowing fixation procedures to be carried out in less sophisticated facilities with non-anatomy staff.  相似文献

In this article, we examine how models working on Chaturbate, one of the world’s most popular adult webcam platforms, negotiate and make sense of the dynamic ways in which this platform configures their competitive environment. By combining different perspectives from the field of economic sociology, we demonstrate how competition on Chaturbate is shaped by various market devices whose strategic negotiation informs – and is informed by – the moral economy articulated on web forums where models gather to discuss their work experiences and market strategies. We first introduce Chaturbate and the ways in which it organizes market competition, surveying the environment models have to negotiate. We then zoom in on two controversial strategies for beating the competition, each of which upset the moral economy of Chaturbate’s model community. Subsequently, we turn to what models term ‘the hustle,’ which encompasses a number of competitive strategies and criteria judged to be fair and thus legitimate. The final part of our analysis considers the limitations of the hustle, as well as the meritocratic and entrepreneurial discourse that surround it, in light of what we identify as Chaturbate’s ‘manufactured uncertainty.’  相似文献

Anatomical fixation and conservation are required to prevent specimens from undergoing autolysis and decomposition. While fixation is the primary arrest of the structures responsible for autolysis and decomposition, conservation preserves the state of fixation. Although commonly used, formaldehyde has been classified as carcinogenic to humans. For this reason, an adequate substitute was developed. Ethanol-glycerin fixation and thymol conservation are described and compared with formaldehyde and phenol in this technical report. The setup, tissue qualities, financial aspects, and health concerns of this method are discussed. Ethanol-glycerin fixation and thymol conservation provide outstanding haptic and optic tissue qualities. Typical formaldehyde and phenol effects, such as skin, airway, and eye irritation, as well as carcinogenic effects, can be circumvented by using ethanol-glycerin and thymol instead. Ethanol-glycerin fixation is more expensive than formaldehyde and requires an explosion-proof facility. However, the absence of health effects and its convincing tissue qualities balance these higher costs. Therefore, ethanol-glycerin fixation and thymol conservation provide a potential alternative and complement established fixation techniques. The use of carcinogenic formaldehyde and toxic phenol can be effectively restricted through the use of the described method.  相似文献

The Danish e-commerce strategy is a highly ambitious effort to become the world's leading IT nation. Instead of a production-led approach aimed at stimulating domestic hardware and software production, Denmark has pursued a demand-oriented approach focused on promoting the widespread adoption of e-commerce in the Danish society. The Danish government has developed a number of e-commerce initiatives via public-private sector partnerships--an approach we refer to as "governance." So far, it appears that Denmark has been successful in promoting business-to-business (B2B) e-commerce, with a number of Danish companies being global leaders in the use of B2B applications. On the other hand, Denmark has had less success in achieving widespread use of business-to-consumer (B2C) e-commerce. This article analyzes the Danish national environment for e-commerce, discusses four sets of governance initiatives aimed at the development of e-commerce, and analyzes the reasons for its success in B2B and relative failure in B2C adoption.  相似文献

Over the past 10–15?years, state-funded schools have begun to require parents to assume an undefined and infinite personal responsibility. In this article, we investigate how schools organize responsibility games to respond to this challenge and how these games affect the concept of responsibility. We point to a dislocation in the way parents are assigned responsibility, because the definition of responsibility is not only a question of formulating rules or providing advice. We argue that what emerges is a kind of playful hyper responsibility that identifies responsibility as the participation in a process of public exploration by parents of the definition of their specific responsibilities. This has several consequences, one of which is that it becomes difficult to have a political discussion about what can reasonably be expected of parents.  相似文献

This study investigates the effects of a competency‐oriented course and the effects of feedback training on students’ reflection skills. Thirty‐one nursing students enrolled in a conventional course with lectures and assignments following a traditional test. Subsequently, they enrolled in a competency‐oriented course, which included more performance‐oriented tasks based on competencies and a performance‐based assessment. In both courses, half of the students received feedback on their assignments from tutors who were trained in feedback skills (experimental group), while the other half of the students received feedback from non‐trained tutors (control group). After each course, all students wrote a reflection report. Results show that students’ reflection reports after the competency‐oriented course were of a higher quality than the reports after the conventional course. Contrary to our expectations, the quality of the reflection reports of the control group (students supervised by non‐trained tutors) was significantly higher than the quality of reflection reports of the experimental group (students supervised by trained tutors). This study shows that a competency‐oriented design of courses enhances students’ reflection skills, but that the training in feedback skills needs to be reconsidered.  相似文献
