Young children learning in Gaelic: Investigating children's learning experiences in Gaelic-medium pre-school. Research Briefing 6E. Stirling

Gaelic-medium (GM) education is an important part of current efforts to re-vitalise the language in Scotland. Beginning Gaelic-medium education in preschool is seen as a crucial entry point, enhancing the numbers entering GM primary education and facilitating transition to the school learning environment. However, it is essential that GM preschool is of high quality. Government-funded provision is expected to offer children the same learning opportunities as their peers who attend English-medium settings. Meeting these expectations is challenging because most children enter Gaelic-medium preschool from English-speaking homes so that the nursery or playgroup is their only exposure to Gaelic. Our earlier study mapped the range and extent of Gaelic-medium early education and childcare provision but in the research reported here our focus was on what happens within settings, the children’s activities in the playroom and the ways in which practitioners help them to learn Gaelic, as well as ensuring that national expectations about curriculum and learning outcomes are met

Is foreign-currency indexed debt a commitment technology? Some evidence from Brazil and Mexico

We examine the effects of foreign currency-indexed debt upon inflationary expectations in Brazil and Mexico. Conjecturing that markets will view increasing overhangs of foreign currency-indexed debt as a commitment technology that fiscally punishes devaluation, we test whether increasing such overhangs will attenuate the effect of monetary growth upon inflationary expectations. We find some econometric confirmation of these conjectures in both the Brazilian and Mexican cases. Finding that the results are consistent with the notion that increasing the share of dollar indexed debt may also permit some temporary monetary independence even under pegged exchange rate regimes, we present some evidence of independent policy behavior during periods when are model results would suggest it. ; Economic Research Working Paper 9913Money ; Brazil ; Debt ; Financial crises - Latin America ; Indexation (Economics) ; Inflation (Finance) ; Mexico

The openness-inflation puzzle revisited

Dynamic panel estimates show the negative relation between trade openness and inflation found by Romer (1993) but questioned by Terra (1998) became more robust in the 1990s, both among high income OECD and developing countries. Also during the 1990s, openness was associated with less variable inflation and had a stronger disinflation effect in economies with floating exchange rates.Trade

The influence of ship motion of manual control skills

The effects of ship motion on a range of typical manual control skills were examined on the Warren Spring ship motion simulator driven in heave, pitch, and roll by signals taken from the frigate HMS Avenger at 13 m/s (25 knots) into a force 4 wind. The motion produced a vertical r.m.s. acceleration of 0.024g, mostly between 0.1 and 0.3 Hz, with comparatively little pitch or roll. A task involving unsupported arm movements was seriously affected by the motion; a pursuit tracking task showed a reliable decrement although it was still performed reasonably well (pressure and free moving tracking controls were affected equally by the motion); a digit keying task requiring ballistic hand movements was unaffected. There was no evidence that these effects were caused by sea sickness. The differing response to motion of the different tasks, from virtual destruction to no effect, suggests that a major benefit could come from an attempt to design the man/control interface onboard ship around motion resistant tasks

Synthesis of improved phenolic resins

Twenty seven addition cured phenolic resin compositions were prepared and tested for their ability to give char residues comparable to state-of-the-art phenolic resins. Cyanate, epoxy, allyl, acrylate, methacrylate and ethynyl derivatized phenolic oligomers were investigated. The novolac-cyanate and propargyl-novolac resins provided anaerobic char yields at 800 C of 58 percent. A 59 percent char yield was obtained from modified epoxy novolacs. A phosphonitrilic derivative was found to be effective as an additive for increasing char yields. The novolac-cyanate, epoxy-novolac and methacrylate-epoxy-novolac systems were investigated as composite matrices with Thornel 300 graphite fiber. All three resins showed good potential as composite matrices. The free radical cured methacrylate-epoxy-novolac graphite composite provided short beam shear strengths at room temperature of 93.3 MPa (13.5 ksi). The novolac-cyanate graphite composite produced a short beam shear strength of 74 MPa (10.7 ksi) and flexural strength of 1302 MPa (189 ksi) at 177 C. Air heat aging of the novolac-cyanate and epoxy novolac based composites for 12 weeks at 204 C showed good property retention

One-year follow-up of family versus child CBT for anxiety disorders: Exploring the roles of child age and parental intrusiveness.

ObjectiveTo compare the relative long-term benefit of family-focused cognitive behavioral therapy (FCBT) and child-focused cognitive behavioral therapy (CCBT) for child anxiety disorders at a 1-year follow-up.MethodThirty-five children (6-13 years old) randomly assigned to 12-16 sessions of family-focused CBT (FCBT) or child-focused CBT (CCBT) participated in a 1-year follow-up assessment. Independent evaluators, parents, and children rated anxiety and parental intrusiveness. All were blind to treatment condition and study hypotheses.ResultsChildren assigned to FCBT had lower anxiety scores than children assigned to CCBT on follow-up diagnostician- and parent-report scores, but not child-report scores. Exploratory analyses suggested the advantage of FCBT over CCBT may have been evident more for early adolescents than for younger children and that reductions in parental intrusiveness may have mediated the treatment effect.ConclusionFCBT may yield a stronger treatment effect than CCBT that lasts for at least 1 year, although the lack of consistency across informants necessitates a circumspect view of the findings. The potential moderating and mediating effects considered in this study offer interesting avenues for further study

Argumentation in biology : exploration and analysis through a gene expression use case

Argumentation theory conceptualises the human practice of debating. Implemented as computational argumentation it enables a computer to perform a virtual debate. Using existing knowledge from research into argumentation theory, this thesis investigates the potential of computational argumentation within biology. As a form of non-monotonic reasoning, argumentation can be used to tackle inconsistent and incomplete information - two common problems for the users of biological data. Exploration of argumentation shall be conducted by examining these issues within one biological subdomain: in situ gene expression information for the developmental mouse. Due to the complex and often contradictory nature of biology, occasionally it is not apparent whether or not a particular gene is involved in the development of a particular tissue. Expert biological knowledge is recorded, and used to generate arguments relating to this matter. These arguments are presented to the user in order to help him/her decide whether or not the gene is expressed. In order to do this, the notion of argumentation schemes has been borrowed from philosophy, and combined with ideas and technologies from arti cial intelligence. The resulting conceptualisation is implemented and evaluated in order to understand the issues related to applying computational argumentation within biology. Ultimately, this work concludes with a discussion of Argudas - a real world tool developed for the biological community, and based on the knowledge gained during this work
