Early Histories of School‐Aged Children With Attention‐Deficit/ Hyperactivity Disorder

In a prospective study of developmental outcomes in relation to early‐life otitis media, behavioral, cognitive, and language measures were administered to a large, diverse sample of children at 2, 3, 4, 6, and 9–11 years of age (N = 741). At 9–11 years of age, 9% of the children were categorized as having attention‐deficit/hyperactivity disorder (ADHD) based on parent report. Compared to the non‐ADHD group, the ADHD group had higher (i.e., less favorable) scores on parent and teacher versions of the Child Behavior Checklist at all ages. Children in the ADHD group also had lower scores on cognitive and receptive language measures in preschool. The findings support the concept that ADHD is a cognitive as well as a behavioral disorder.     

Advisory services and farm-level sustainability profiles: an exploration in nine European countries

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.     

Perceived environment in relation to objective and self-reported physical activity in Spanish youth. The UP&DOWN study

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.     

Cognition in the African Grey parrot: Preliminary evidence for auditory/vocal comprehension of the class concept

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).     

How students use their libraries: A case study of four academic libraries

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.

Learning about the types of plastic wastes: effectiveness of inquiry learning strategies

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.
