Purpose: This study explores the use of advisory services by farm managers and its linkages with the economic, environmental and social performance of farms.
Design/methodology/approach: Using cluster analysis we determined groups of farms according to their sustainability performance and explored the correlations between contacts with advisory services and a set of farm-level sustainability indicators.
Findings: There exist significant differences in the number of farmers’ contacts with advisory services across countries, type of farms, farmers’ degree of agricultural education, utilized agricultural area, legal type of farm ownership and economic size of the farms. We identified three groups of farms that have different sustainability performance, are different in farm characteristics and relate differently to advisory services. The number of contacts with advisory services is positively related to the adoption of innovations, the number of information sources utilized and the adoption of farm risk management measures. We find no clear linear relationship between advisory services and environmental sustainability.
Theoretical implications: This study derives hypotheses to analyze causalities between indicators of farm-level sustainability and advisory services.
Practical implications: Results suggest the importance of taking into account the heterogeneity of farming systems for the design, targeting and evaluation of advisory services. In addition, results confirm the importance of selection of indicators that can be used in multiple sites.
Originality/value: We used a harmonized indicator of advisory services and a harmonized set of farm-level sustainability indicators in nine different EU countries that could be used to evaluate the role of advisory services in the achievement of multiple objectives in different groups of farms in multiple sites. 相似文献
The aims of the present study were to assess the association of environmental perception with objective and self-reported physical activity (PA) and the relation between environmental perception and meeting PA recommendations on children and adolescents. A sample of 1520 youth (770 boys) aged 8–18 years (12.1 ± 2.5 years) from the UP&;DOWN study were included in the data analyses. Environmental perception was assessed with the short adapted version of the ALPHA environmental questionnaire. PA was objectively (accelerometers) and self-reported measured (PA Questionnaire for Children, Patient-centered Assessment and Counseling for Exercise Questionnaire and Finnish PA Index). Linear regression models were used to assess the association of environmental perception with PA. Bivariate logistic regression models were used to assess differences between environmental perception and meeting PA recommendations. Environmental perception was positively associated with both objective and self-reported PA. Some differences were found in the association of environmental perception and PA between sex- and age-specific groups. Youth who perceived a more favourable environment were more likely to meet PA recommendations (at least 60 min · day?1 of moderate to vigorous PA (MVPA)). Results suggest that environmental perceptions of children and adolescents may play an important role in achieving higher levels of PA. 相似文献
An African Grey parrot, previously taught to discriminate more than 40 objects by means of vocal labels, has now acquired a limited understanding of abstract class concepts. The subject, Alex, can routinely decode and successfully reply vocally to queries concerning either coloror shape for exemplars which simultaneously incorporate both variables (e.g., colored and shaped keys, wood, and rawhide). 相似文献
The purpose of this study was to explore the similarities and differences in student behavior in or uses of four academic libraries in the greater New York City area. Using on-site observations and semistructured interviews, the authors collected data about resources and tools used by students as well as their academic and nonacademic activities and contributing factors. Across all four libraries, the study identified that students were actively engaged in academic pursuits utilizing multiple library resources while working with print and digital tools. Students were also observed resting, eating, and engaging in other nonacademic activities. The variations in student behaviors across the four libraries can be explained by contextual variables that influence students' behavior in a library, including student demographics, academic requirements, work habits, and disciplinary affiliations. 相似文献

This study aims to examine the impacts of the inquiry learning strategies employed in a ‘Plastic Education Project’ on primary students' knowledge, beliefs and intended behaviour in Hong Kong. Student questionnaires and a test on plastic types were adopted for data collection. Results reveal that the inquiry learning strategies significantly improved students' knowledge of the types of plastic wastes and their corresponding beliefs. However, the strategies seemed not to change students' intended behaviour regarding plastic waste classification and management. The implications of the study for further learning and teaching in environmental education are discussed. 相似文献
This article describes the metacognitive processes in which good readers engage before, during, and after reading and the
strategies instruction that fosters these processes. Benchmark School, a school in Media, PA for struggling readers, is provided
as an example of how a grades 1–8, across-the-curriculum strategies program was developed based on the research of the late
1980s and early 1990s and continues to evolve in the 21st century as an evidence-based program. Examples of present-day, across-the-curriculum
strategies instruction are provided. 相似文献

Most journals have editorial boards. Their composition, what the individual members do, and how they operate will vary, but they are generally recognized as having certain central roles. What makes a good editor? How can potential editors be identified and then persuaded to join an editorial board? Once on the board, what can be done to keep them happy, committed, and working productively for the journal? What sorts of problems can arise, and how can they be avoided? These are some of the questions dealt with in this article. 相似文献
