Approaches to the embedding of sustainability into the engineering curriculum - where are we now, and how do our graduates become global engineers?

This paper presents a resume of how the topic of sustainability can become fully-integrated into the engineering curriculum in the UK, and how this needs to evolve toward consideration of how graduates could be better developed as global engineers. The paper begins by providing a justification as to why sustainability is an important feature of the already overcrowded engineering curriculum, and briefly reports, through illustrative examples, on alternative approaches which currently embed sustainability into the engineering curriculum. The paper makes the case that it is timely now to re-address the learning outcomes in order to enhance the students’ experience beyond just the inclusion of new curriculum content It does this by consideration of the identified drivers that range from the accrediting bodies and from the aspirations of employers, through revised approaches to embed sustainability, to the consideration of students’ own perceptions of sustainability and ultimately to their becoming employed as global engineers. The paper therefore discusses both the current and planned work toward supporting the development of engineering graduates into global citizens, with a greater emphasis upon their responsibility to ensure a sustainable future world, moving beyond sustainability awareness towards informed application of sustainability thinking

An introduction to sustainable development in the Engineering curriculum

The guide looks at why and how EngSD is included in the engineering curriculum and considers embedded versus discrete approaches. It discusses approaches to teaching and learning for EngSD, including examples of EngSD within the curriculum and a ‘what next?’ section, which points the reader towards further areas of study and practice. As an introduction to EngSD within engineering programmes, this guide does not seek to prescribe courses of action but rather aims to outline the main opportunities, sources of guidance and educational resources which may enable informed debate and decision making. Both personal action and leadership are required in equal measure if graduate engineers are to meet the needs of society, even when society itself may not be taking action (Blincoe, 2009). Readers of this guide should, therefore, feel empowered toward personal action and leadership in the encouragement of their future graduates in becoming effective global engineers

Giant Pulses from the Millisecond Pulsar B1821-24

We have carried out a survey for `giant pulses' in 5 millisecond pulsars. We detect individual pulses from the high Edot pulsar PSR B1821-24 with energies exceeding 50x the mean pulse energy. These giant pulses are concentrated in a narrow phase window coincident with the power-law non-thermal pulse seen in hard X-rays. This is the third example of the giant pulse phenomenon. It supports the idea that large B fields in the outer magnetosphere are critical to the formation of such pulses and further suggests a direct connection between giant pulses and high energy emission.Comment: 6pp, 3 figures.

"Dispersion management" for solitons in a Korteweg-de Vries system

The existence of ``dispersion-managed solitons'', i.e., stable pulsating solitary-wave solutions to the nonlinear Schr\"{o}dinger equation with periodically modulated and sign-variable dispersion is now well known in nonlinear optics. Our purpose here is to investigate whether similar structures exist for other well-known nonlinear wave models. Hence, here we consider as a basic model the variable-coefficient Korteweg-de Vries equation; this has the form of a Korteweg-de Vries equation with a periodically varying third-order dispersion coefficient, that can take both positive and negative values. More generally, this model may be extended to include fifth-order dispersion. Such models may describe, for instance, periodically modulated waveguides for long gravity-capillary waves. We develop an analytical approximation for solitary waves in the weakly nonlinear case, from which it is possible to obtain a reduction to a relatively simple integral equation, which is readily solved numerically. Then, we describe some systematic direct simulations of the full equation, which use the soliton shape produced by the integral equation as an initial condition. These simulations reveal regions of stable and unstable pulsating solitary waves in the corresponding parametric space. Finally, we consider the effects of fifth-order dispersion.Comment: 19 pages, 7 figure

Optimal statistical inference in the presence of systematic uncertainties using neural network optimization based on binned Poisson likelihoods with nuisance parameters

Data analysis in science, e.g., high-energy particle physics, is often subject to an intractable likelihood if the observables and observations span a high-dimensional input space. Typically the problem is solved by reducing the dimensionality using feature engineering and histograms, whereby the latter technique allows to build the likelihood using Poisson statistics. However, in the presence of systematic uncertainties represented by nuisance parameters in the likelihood, the optimal dimensionality reduction with a minimal loss of information about the parameters of interest is not known. This work presents a novel strategy to construct the dimensionality reduction with neural networks for feature engineering and a differential formulation of histograms so that the full workflow can be optimized with the result of the statistical inference, e.g., the variance of a parameter of interest, as objective. We discuss how this approach results in an estimate of the parameters of interest that is close to optimal and the applicability of the technique is demonstrated with a simple example based on pseudo-experiments and a more complex example from high-energy particle physics

Design issues for VREs: can richer records of meetings enhance collaboration?

Technologies for collaboration have advanced significantly in the past ten years. Through tools such as the Access Grid (AG), it is now possible to conduct multi-site meetings involving large numbers of participants interacting using high quality and video and sharing data. Virtual Venues within the AG toolkit store data, documents, applications and services which can be accessed across multiple sites. These documents might include records of the meetings themselves. We discuss ways in which such records can be made navigable and re-usable so that collaborators can achieve a shared understanding of meetings’ work

Investigating the structure of the autism-spectrum quotient using Mokken scaling

Traits similar to those shown in autism spectrum condition (ASC) are apparent in relatives of individuals with ASC, and in the general population without necessarily meeting diagnostic criteria for an ASC. We assess whether the Autism-Spectrum Quotient (AQ), a self-report measure, has hierarchical properties using Mokken scaling. Hierarchical scales allow the presence of a latent trait to be identified by discovering whether and how many specific items form an ordered array along it. Data were collected from 2 groups: (1) people with ASC (n = 449: 240 males, 209 females, M age 35.4 years, SD = 12.8) and (2) university students (n = 943: 465 males, 475 females, M age = 23.0 years, SD = 8.4). A single Mokken scale was obtained in the data from university students and 3 scales were obtained in the data from people with ASC. The scales all showed moderate Mokken scaling properties with the single scale obtained from university students showing weak invariant item ordering and 2 of the scales from people with ASC showing weak invariant item ordering. The AQ formed reliable Mokken scales. There was a large overlap between the scale from the university student sample and the sample with ASC, with the first scale, relating to social interaction, being almost identical. The present study confirms the utility of the AQ as a single instrument that can dimensionalize autistic traits in both university student and clinical samples of ASC, and confirms that items of the AQ are consistently ordered relative to one another

The placement, fate and effectiveness of granular nematicides in potato beds infested with the potato cyst nematode <i>Globodera pallida</i> (stone)

The chemical control of the potato cyst nematode (PCN) by granular nematicides when applied and incorporated into potato seed beds was investigated to assess problems connected with incorporation using bed cultivation machinery. Fluorescent tracer granule work using a range of granular nematicide incorporation methods suggested that differences exist between the incorporation methods in terms of placement of the fluorescent granules in the planted potato bed. Incorporation of tracer initially by a bed tiller followed by a second incorporation by a stone and clod separator produced a distribution of tracer greater than 40cm deep in the planted bed. Incorporation of tracer by a stone and clod separator with application of tracer halfway up the first web produced concentrated bands of tracer in the sides of the planted bed. No visible differences in tracer distribution occurred between other treatments. The differences observed between incorporation techniques during the fluorescent tracer granule work were shown not to be important in terms of PCN control or yield in the first year's field experiments. The second year of field experimentsa ssessedth e incorporation of the granular nematicide Vydate (10G) before, during or after stone and clod separation of potato beds. These field experiments suggested that timing of nematicide incorporation in relation to stone and clod separation had no effect on potato yield or control of PCN. As in the first year's experiments, significant differences occurred between plots treated or not treated with a granular nematicide, but not between incorporation methods. Work describing the field concentration of oxamyl immediately after planting showed similarities to the distribution of tracer granules observed in the soil hall studies. The subsequent distribution of oxamyl 3 weeks after planting showed no redistribution of the nematicide in the potato bed. The depth of potato planting is thought to be responsible for the uniformity of PCN control and crop response to nematicide treatment regardless of incorporation method as seed was planted below the nematicide treated layer. Evaluation of a diagnostic kit used for detecting oxamyl in soil showed that the kit was well suited for this purpose and its use is discussed in the light of the findings of this study

Being at home abroad: Londoners ‘ong continong’ (on the continent) in the 19th-century comics of Marie Duval.

Marie Duval is one of the great unsung cartoonists of the 19th century. Her work for the journal Judy between 1869-1885 took comic strips into new and unexpected areas. One of her interests was travel, and in particular the way in which working class and lower middle class people were starting to go on holiday abroad. This phenomenon was a continuation of the notion of the ‘tour’, an upper class pursuit aimed at improving one’s cultural capital though seeing the (usually classical) sights. However, the new cheap package tours of the late 19th century allowed a ‘lower sort’ to participate – with obvious comedic possibilities for the cartoonist. This paper will explore Duval’s take on the clash of manners when ordinary British people came into contact with ‘funny foreigners’ (in particular the French, the Swiss, and the Germans), while at the same time indicating her very knowing references to cartooning traditions (Busch, Rowlandson, etc.) and her ‘other’ career as a popular actress. The paper is part of a bigger project about Duval, funded by the Arts and Humanities Research Council, and will be presented jointly by the project’s three leads
