Learners’ perceptions of being identified as very able: insights from Modern Foreign Languages and Physical Education

While learners’ attitudes to Modern Foreign Languages (MFL) and to Physical Education (PE) in the UK have been widely investigated in previous research, an under-explored area is learners’ feelings about being highly able in these subjects. The present study explored this issue, among 78 learners (aged 12-13) from two schools in England, a Specialist Language College, and a Specialist Sports College. Learners completed a questionnaire exploring their feelings about the prospect of being identified as gifted/talented in these subjects, and their perceptions of the characteristics of highly able learners in MFL and PE. Questionnaires were chosen as the data collection method to encourage more open responses from these young learners than might have been elicited in an interview. While learners were enthusiastic about the idea of being highly able in both subjects, this enthusiasm was more muted for MFL. School specialism was related to learners’ enthusiasm only in the Sports College. Learners expressed fairly stereotypical views of the characteristics of the highly able in MFL and PE. The relevance of these findings for motivation and curriculum design within both subjects is discussed.

Are normative properties descriptive properties?

Some philosophers think that normative properties are identical to descriptive properties. In this paper, I argue that this entails that it is possible to say which descriptive properties normative properties are identical to. I argue that Frank Jackson’s argument to show that this is possible fails, and that the objections to this argument show that it is impossible to say which descriptive properties normative properties are identical to. I conclude that normative properties are not identical to descriptive properties. I then show that if we combine this conclusion with the conclusion of a different argument that Jackson has given to show that there are no irreducibly normative properties, it follows that there are no normative properties at all.

‘Everyone now is concentrating on the mining’: drivers and implications of rural economic transition in the Eastern Region of Ghana

Artisanal and small-scale mining (ASM) is replacing smallholder farming as the principal income source in parts of rural Ghana. Structural adjustment policies have removed support for the country’s smallholders, devalued their produce substantially and stiffened competition with large-scale counterparts. Over one million people nationwide are now engaged in ASM. Findings from qualitative research in Ghana’s Eastern Region are drawn upon to improve understanding of the factors driving this pattern of rural livelihood diversification. The ASM sector and farming are shown to be complementary, contrary to common depictions in policy and academic literature.

Parallel induction of modular classification rules

The Distributed Rule Induction (DRI) project at the University of Portsmouth is concerned with distributed data mining algorithms for automatically generating rules of all kinds. In this paper we present a system architecture and its implementation for inducing modular classification rules in parallel in a local area network using a distributed blackboard system. We present initial results of a prototype implementation based on the Prism algorithm.

Modulation of hTREK-1 by carbon monoxide

TREK-1 is a background K channel important in the regulation of neuronal excitability. Here, we demonstrate that recombinant human TREK-1 is activated by low concentrations of carbon monoxide (CO) and nitric oxide (NO), applied via their respective donor molecules. Related channels hTASK-1 and hTASK-3 were unaffected by CO. Effects of both CO and NO were prevented by preincubation of cells with the protein kinase G inhibitor, Rp-8-Br-PET-cGMPS. The effects of CO were independent of NO formation. At higher concentrations, both NO and CO were inhibitory. As both NO and CO are important neuronal gasotransmitters and TREK is crucial in regulating neuronal excitability, our results provide a novel means by which these gases may modulate neuronal activity.

Atlantic meridional heat transports in two ocean reanalyes evaluated against the RAPID array

The Atlantic meridional overturning circulation in two versions of the NEMO ¼° global ocean model has been compared with the RAPID transport array at 26oN. Both model versions reproduce the mean MOC strength well although the Florida Straits flows differ because the pathway of the Gulf Stream is not strongly constrained at this resolution. Both models however have a mean meridional heat transport of 1.07PW, much lower than the 1.35PW from RAPID observations in Apr04-Oct07. Much of the heat transport discrepancy is due to lower transports in summer across the MidOcean (Bahamas-Africa) section, due to stronger southward geostrophic flows in the top 100m where the water is warmest. Seasonal thermocline changes increase temperature differences across the basin driving stronger geostrophic shear, but this effect is much weaker in the top 100m of the RAPID velocity data. The effect accounts for a reduction of 1.1Sv in MOC and 0.1PW in heat transports. The rest of the discrepancy comes from lower Ekman transports from using ERAInterim winds instead of QuikSCAT, a smaller zonally-varying “Eddy” heat transport component, estimated from repeat XBT sections in the observations, and the southward throughflow in the model. Other differences in depth structure of the model MOC and RAPID observations are described but have much less impact on heat transports.

Some numerical experiments on the effect of the variation of static stability in two-layer quasi-geostrophic models

A method to solve a quasi-geostrophic two-layer model including the variation of static stability is presented. The divergent part of the wind is incorporated by means of an iterative procedure. The procedure is rather fast and the time of computation is only 60–70% longer than for the usual two-layer model. The method of solution is justified by the conservation of the difference between the gross static stability and the kinetic energy. To eliminate the side-boundary conditions the experiments have been performed on a zonal channel model. The investigation falls mainly into three parts: The first part (section 5) contains a discussion of the significance of some physically inconsistent approximations. It is shown that physical inconsistencies are rather serious and for these inconsistent models which were studied the total kinetic energy increased faster than the gross static stability. In the next part (section 6) we are studying the effect of a Jacobian difference operator which conserves the total kinetic energy. The use of this operator in two-layer models will give a slight improvement but probably does not have any practical use in short periodic forecasts. It is also shown that the energy-conservative operator will change the wave-speed in an erroneous way if the wave-number or the grid-length is large in the meridional direction. In the final part (section 7) we investigate the behaviour of baroclinic waves for some different initial states and for two energy-consistent models, one with constant and one with variable static stability. According to the linear theory the waves adjust rather rapidly in such a way that the temperature wave will lag behind the pressure wave independent of the initial configuration. Thus, both models give rise to a baroclinic development even if the initial state is quasi-barotropic. The effect of the variation of static stability is very small, qualitative differences in the development are only observed during the first 12 hours. For an amplifying wave we will get a stabilization over the troughs and an instabilization over the ridges.

The abandoned mandatory OFR: a lost opportunity for SER?

Purpose – An important outcome of the UK Company Law Review (CLR) involved draft regulations for a mandatory operating and financial review (OFR). The unprecedented abandonment of this mandatory OFR in November 2005 threw debate about the genuine motivations underlying the CLR into disarray. This paper seeks to reinterpret the abandonment of a mandatory OFR using interview research. Design/methodology/approach – The authors conducted a series of 24 interviews with companies from the FTSE100 between May and August 2004, prior to the abandonment. Findings – The interviews showed that the OFR was perceived as an appropriate vehicle for social and environmental reporting (SER). The interviewees considered that a mandatory OFR would provide a means of forcing SER into the mainstream and making it mandatory at a basic level. The interviews revealed that processes for the identification of material SER differ widely between organisations, ranging from embryonic to highly structured. Further, interviewees believed that directors had the final veto on inclusion of information. Despite directors' inclination to hide behind materiality as a means of avoiding SER, interviewees did not view the proposed mandatory OFR as “greenwash” but as a vehicle that would increase stakeholder confidence, as processes underlying the proposed OFR would be audited. Practical implications – The research implies that abandoning the mandatory OFR represented a lost opportunity for SER. Originality/value – The paper provides new evidence on the processes of materiality decision making in the SER area as well as strong endorsement of the mandatory OFR, contrary to the government turn-around.

Model simulations and aircraft measurements of vertical, seasonal and latitudinal O3 and CO distributions over Europe

During a series of 8 measurement campaigns within the SPURT project (2001-2003), vertical profiles of CO and O3 have been obtained at subtropical, middle and high latitudes over western Europe, covering the troposphere and lowermost stratosphere up to ~14 km altitude during all seasons. The seasonal and latitudinal variation of the measured trace gas profiles are compared to simulations with the chemical transport model MATCH. In the troposphere reasonable agreement between observations and model predictions is achieved for CO and O3, in particular at subtropical and mid-latitudes, while the model overestimates (underestimates) CO (O3 in the lowermost stratosphere particularly at high latitudes, indicating too strong simulated bi-directional exchange across the tropopause. By the use of tagged tracers in the model, long-range transport of Asian air masses is identified as the dominant source of CO pollution over Europe in the free troposphere.

Implicit learning and imperceptible influence: Syncretic literacy of multilingual Chinese children.

This article reports on an ethnographic study involving the literacy practices of two multilingual Chinese children from two similar yet different cultural and linguistic contexts: Montreal and Singapore. Using syncretism as a theoretical tool, this inquiry examines how family environment and support facilitate children’s process of becoming literate in multiple languages. Informed by sociocultural theory, the inquiry looks in particular at the role of grandparents in the syncretic literacy practices of children. Through comparative analysis, the study reveals similarities and differences that, when considered together, contribute to our understanding of multilingual children’s creative forms of learning with regard to their rich literacy resources in multiple languages, the imperceptible influences of mediators, various learning styles and syncretic literacy practices.

The level of compliance with the International Code of marketing of breast-milk substitutes: does it matter to stock markets?

The present paper explores, theoretically, and empirically, whether compliance with the International Code of marketing of breast-milk substitutes impacts on financial performance measured by stock markets. The empirical analysis, which considers a 20-year period, shows that stock markets are indifferent to the level of compliance by manufacturers with the International Code. Two important issues emerge from this result. Based on our finding that financial performance as measured by stock markets cannot explain the level of compliance, the first issue refers to what alternative types of mechanisms drive manufacturers who comply the least with voluntary codes such as the International Code. Conversely, from our finding that stock markets do not reward the most compliant, the second issue raised is an inherent weakness of stock markets to fully incorporate social and environmental values.

Understanding and representing atmospheric convection across scales: recommendations from the meeting held at Dartington Hall, Devon, UK, 28–30 January 2013

As weather and climate models move toward higher resolution, there is growing excitement about potential future improvements in the understanding and prediction of atmospheric convection and its interaction with larger-scale phenomena. A meeting in January 2013 in Dartington, Devon was convened to address the best way to maximise these improvements, specifically in a UK context but with international relevance. Specific recommendations included increased convective-scale observations, high-resolution virtual laboratories, and a system of parameterization test beds with a range of complexities. The main recommendation was to facilitate the development of physically based convective parameterizations that are scale-aware, non-local, non-equilibrium, and stochastic.
