‘Nature’ and the ‘environment’ in Jamaica’s primary school curriculum guides

In cases where environmental education is institutionalised within schools, the curriculum can affect what and how students learn about ‘nature’ and the ‘environment’. In Jamaica, schools are considered important settings for environmental education; the curriculum therefore includes environmental issues. Using content analysis, representations of ‘nature’ and the ‘environment’ in the nation’s primary level Curriculum Guides were examined. Findings indicate that although many units emphasise an anthropocentric view of nature, this is tempered by depictions of nature’s fragility and, in some instances, nature’s ‘divine’ dimensions. Several curricular units also facilitate student’s creative engagement with nature, allowing for multiple views of the natural world.

Modeling and validation of autoinducer-mediated bacterial gene expression in microfluidic environments

Biosensors exploiting communication within genetically engineered bacteria are becoming increasingly important for monitoring environmental changes. Currently, there are a variety of mathematical models for understanding and predicting how genetically engineered bacteria respond to molecular stimuli in these environments, but as sensors have miniaturized towards microfluidics and are subjected to complex time-varying inputs, the shortcomings of these models have become apparent. The effects of microfluidic environments such as low oxygen concentration, increased biofilm encapsulation, diffusion limited molecular distribution, and higher population densities strongly affect rate constants for gene expression not accounted for in previous models. We report a mathematical model that accurately predicts the biological response of the autoinducer N-acyl homoserine lactone-mediated green fluorescent protein expression in reporter bacteria in microfluidic environments by accommodating these rate constants. This generalized mass action model considers a chain of biomolecular events from input autoinducer chemical to fluorescent protein expression through a series of six chemical species. We have validated this model against experimental data from our own apparatus as well as prior published experimental results. Results indicate accurate prediction of dynamics (e.g., 14% peak time error from a pulse input) and with reduced mean-squared error with pulse or step inputs for a range of concentrations (10 μM–30 μM). This model can help advance the design of genetically engineered bacteria sensors and molecular communication devices.     

Specific and general information sharing among competing academic researchers

We examine information sharing among academics during the research process and show it is context dependent because of differences in trade-offs. When researchers respond to specific requests for information or materials, potential future reciprocity is weighed against the current loss of competitiveness, while general sharing intermediate results in an open forum is driven by the need for feedback versus potential misappropriation. We formally model these trade-offs and empirically test for differences using a survey of German and UK bio-scientists. Increased competition has a negative impact on sharing in both contexts. But career stage has an effect only on specific sharing with untenured faculty less likely to share. Further, scientists in larger teams are more likely to share specifically, but less likely to share generally. The importance of patents for one's reputation reduces sharing in both contexts, but the effect is greater for general information sharing.     

The IFLA Trend Report: Looking Beyond the Walls in Library Planning

Strategic planning requires us to stop and take a closer look at our organizations and consider the impact that changes in the profession are causing, influenced by the society around us. These considerations lead us past our library walls, past our institutional walls and into a more speculative world of changes in the technological society. Scholars and pundits have provided us with many scenarios for the future, including a world of solely electronic resources and hyper-connected users. But how closely does this match reality and what are the trends in our larger society that will affect how we work in the future. This article provides an overview of several reports on the students and technologies that we work with and closely explores the IFLA Trend Report. The report was developed after discussions with individuals representing many non-academic, non-library organizations and provides us with a view of the larger trends forecast for the information society. The report is envisioned as a living document that invites further comment and wider distribution to the library world and beyond.     

Communicating aims and learning goals in physical education: part of a subject for learning?

Based on a socio-cultural perspective on learning, the aim of this article is to examine how aims and learning goals are communicated in physical education (PE) practice. A special focus is on scrutinising how teaching practices are framed in terms of whether and how the aims and learning goals are made explicit or not to students. The aim is also to relate these kinds of communications to different movement cultures. The result shows that many of the students taking part in the study do not understand what they are supposed to learn in PE. However, if the goals are well articulated by teachers, the students are more likely to both understand and be aware of the learning outcomes and what to learn in PE. The opposite is also true. If the goals and objectives are not clarified, students find it difficult to state the learning objectives and know what they are supposed to learn.     

Defining Peer-to-peer Learning – from an Old ‘Art of Practice’ to a New Mode of Forest Owner Extension?

Purpose: This paper explores the concept of peer-to-peer learning (P2PL) in the context of North-European small-scale forest owners. The aim is to develop a framework for initiating new and evaluating already existing forest owners' P2PL communities.

Design: Previous studies of peer-learning are used to determine and justify eight dimensions for forest owners' P2PL. To demonstrate and test the operability of the dimensions, two potential forest owners' peer-learning cases are described. The Finnish case focuses on forest owner clubs based on group interview data and the coordinator's interview, and in the Swedish case an ongoing study circle was observed and its participants interviewed.

Findings: The eight P2PL dimensions defined are: initiation, reinforcement, content profile, participant profile, schedule, role of professionals, responsibility and role continuity. Of the described cases, Finnish forest owner clubs rely heavily on the expertise of the invited forest professionals, while owners themselves have a stronger role in Swedish study circles.

Practical Implications: The two studied cases and the fictional example demonstrate how the framework defined can be used when assessing real life cases. The framework allows describing consistently P2PL, when designing new practices or implementing step-by-step changes to modify existing P2PL practices.

Value: The framework gives new insights into the research of forest owner extension, which has had an increasing interest towards P2PL approach, but where its conceptualisation has remained vague. However, since the domain of the study is novel, further research with various case examples is needed to develop both the theoretical framework and real life practices.     

Outcomes of structured teaching for children on the autism spectrum: does the research evidence neglect the bigger picture?

The adoption of ‘structured teaching’ is evident in educational settings worldwide and has fast become one of the key ‘tools’ in autism education. As calls for evidence‐based practice have increased, research evidence has grown to interrogate the effectiveness of structured teaching components. Previous systematic literature reviews of the research evidence suggest that structured teaching has positive effects upon problem behaviours and also increases engagement and independent task organisation. This literature review builds upon previous reviews in order to explore the effects of structured teaching upon behaviour and learning, asking what the research evidence actually measures in relation to these two concepts. Gaps in the research evidence are identified, and discussion focuses upon the need for research which investigates the role of structured teaching components in meaningful learning, the need for greater attention to evaluate social validity of the approach which takes into account those who implement and indeed those who receive the intervention and finally the need for research to analyse the effects of structured teaching upon alternative outcomes of ‘well‐being’ and ‘quality of life’.     

Taking Stock of Two Decades of Attachment Transmission Gap: Broadening the Assessment of Maternal Behavior

This report aimed to investigate the capacity of maternal behaviors tailored to children's attachment and exploration systems to jointly explain the well‐known mother–child transmission of attachment. Four home visits were conducted between ages 7 months and 2 years with 130 mother–child dyads to assess maternal attachment state of mind, sensitivity, autonomy support, and mother–child attachment security. Results showed that together, maternal sensitivity and autonomy support fully accounted for the relation between maternal and child attachment, that they each accounted for a unique portion of this relation, and that the magnitude of these mediated pathways was equivalent. These results suggest that the attachment transmission gap can be narrowed by the use of a theory‐driven multidimensional approach to maternal behavior.     

Local Observed‐Score Kernel Equating

Three local observed‐score kernel equating methods that integrate methods from the local equating and kernel equating frameworks are proposed. The new methods were compared with their earlier counterparts with respect to such measures as bias—as defined by Lord's criterion of equity—and percent relative error. The local kernel item response theory observed‐score equating method, which can be used for any of the common equating designs, had a small amount of bias, a low percent relative error, and a relatively low kernel standard error of equating, even when the accuracy of the test was reduced. The local kernel equating methods for the nonequivalent groups with anchor test generally had low bias and were quite stable against changes in the accuracy or length of the anchor test. Although all proposed methods showed small percent relative errors, the local kernel equating methods for the nonequivalent groups with anchor test design had somewhat larger standard error of equating than their kernel method counterparts.
