Interventions for educating children who have attended the emergency room for asthma (Review)

Background: Asthma is one of the most common reasons for paediatric admissions to hospital, with substantial cost to the community. There is some evidence to suggest that many hospital admissions could be prevented with effective education about asthma and its management.
Objectives: To conduct a systematic review of the literature in order to identify whether asthma education leads to improved health outcomes in children who have attended the emergency department for asthma.
Search strategy: We searched the Cochrane Airways Group trials register, including MEDLINE, EMBASE, and CINAHL databases, and reference lists of trials and review articles.
Selection criteria: Randomised controlled trials or controlled clinical trials of asthma education for children who had attended the emergency department for asthma, with or without hospitalisation, within the previous 12 months. Data collection and analysis:Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information.
Main results: Eight trials involving 1407 patients were included, in all the education was provided by nurses or researchers. Compared to control (usual care or lower intensity education) education did not reduce subsequent emergency department (ED) visits [4 trials; relative risk (RR)= 0.87, 95% confidence interval (CI) 0.37 to 2.08], hospital admissions [5 trials; RR=0.74, 95% CI 0.38 to 1.46] and unscheduled doctor visits [5 trials; RR= 0.74, 95% CI 0.49 to 1.12). Each analysis showed evidence of heterogeneity among the studies (P<0.01). Subgroup analyses by the overall difference in scale of intervention between treatment and control groups (comprehensive programme versus information only) or the timing of the intervention/recruitment (early versus delayed) gave similar results to the main analysis and still revealed significant heterogeneity between trials. Authors' conclusions: On the basis of the published trials, there is no firm evidence to support the use of asthma education for children who have attended the emergency department for asthma as a means of reducing subsequent ED visits, hospital admissions or unscheduled doctor visits. Some trials appeared to show clear evidence of benefit, but reasons for differences between these and the negative studies is not clear. More research is required.

Review of applications of the Cutting Angle methods

The theory of abstract convexity provides us with the necessary tools for building accurate one-sided approximations of functions. Cutting angle methods have recently emerged as a tool for global optimization of families of abstract convex functions. Their applicability have been subsequently extended to other problems, such as scattered data interpolation. This paper reviews three different applications of cutting angle methods, namely global optimization, generation of nonuniform random variates and multivatiate interpolation.

States, markets and communities : is there room for educational leadership?

This paper attempts a comparative analysis of classification and framing relationships as they are exemplified in the four papers presented in this Special Issue. In particular, it interrogates Bernstein's assertion that education is simply a relay for power relations external to it and examines approaches to educational leadership and administration that follow from such analysis. It is concluded that in different times and places power relationships external to education are often complex and contested, producing a variety of relays and attempts at classification and framing that serve differing interests and are articulated through policies containing significant internal contradictions. In such circumstances contingency and immediate local influence may affect the practice of educational leadership as well as offering scope for subversion, resistance, simulated consent and collective action. The possibility of a public pedagogy through which such complexities could be articulated is raised and its importance to the practice of educational leadership affirmed.

Extended cutting angle method of global optimization

Methods of Lipschitz optimization allow one to find and confirm the global minimum of multivariate Lipschitz functions using a finite number of function evaluations. This paper extends the Cutting Angle method, in which the optimization problem is solved by building a sequence of piecewise linear underestimates of the objective function. We use a more flexible set of support functions, which yields a better underestimate of a Lipschitz objective function. An efficient algorithm for enumeration of all local minima of the underestimate is presented, along with the results of numerical experiments. One dimensional Pijavski-Shubert method arises as a special case of the proposed approach.

Engagement and learning through social software in finance : the trading room experience

The introduction of a social software blog space called “The Trading Room” in an undergraduate Finance unit for an assessment task generated a great deal of activity to support student learning. A subsequent evaluation of this pilot demonstrated that students perceived high value in the opportunity it provided for them to reaffirm theories, obtain individualized feedback and benchmark their work against others. Whilst assessment is generally seen as both the carrot and the stick of learning, and certification; students in the study reported that they would still participate in reading and posting to the “Trading Room” blog even if there was no assessment requirement! Additionally they did not see any value in the environment as a purely social space, reporting that they saw it primarily as a professional educational community. It would appear that just as there are different communities in the real world social space, there are also different types of communities in the online space. Context, structure and activity design, perhaps are the most important facets of online interaction for learning.

Reforms in the Bangladesh agriculture input sector : room for complacency?

Market-based reforms implemented in the agricultural input management system are often claimed to be one of the success stories in Bangladesh. Based on the findings of 154 surveys and 16 in-depth interviews with the stakeholders during 2003-2004, the paper found that although there have been some notable achievements, the reforms have not achieved their expected outcomes and more importantly, in cases where they have been achieved, their sustainability is in question. The paper discusses the underlying reasons for the success and the problems of the reforms and also offers some policy recommendations to resolve the gap between the expected and the achieved outcomes. In the context of increasing donor pressure for adopting market-based reforms, the findings are likely to have important implications for both the donors and other countries in South Asia.

The room that was

Wood, sensor, found office chair, DVD player and screen, spy-hole, carpet 1.9x2.5x7m. The ghost of a mad astormonk inhabits the space the viewer sits in. The Room That Was creates a new learning space for the improvement of the unco-operative body – a mobile mnemonia room. It is a place where the subject’s memory can be rendered to suit other points of view. The subject can be indoctrinated anytime, anywhere, and by any method inside the The Room That Was – especially designed for the dimensions of the average sized human body (astromonk – an incipient being). It is a mobile asylum for the European consciousness (much like Australia).

Deformation mechanisms in mg alloys and the challenge of extending room-temperature Plasticity

Magnesium alloys show promise for application in formed components where weight saving is an advantage. In most instances forming is carried out at elevated temperatures. However, there are considerable gains to be had if forming can be carried out under ambient conditions. The present article outlines some of the difficulties that lie in the way of achieving this objective. The underlying metallurgical characteristics of the issues are considered and means for overcoming them are discussed. It is concluded that a combination of microstructure and texture control remains a promising strategy.
