The SEFI Maths Working Group: current offerings and future tasks

In this discussion paper we firstly summarise the current offering of the SEFI Mathematics Working Group with regard to orientation for those who are interested in the mathematical education of engineers. Based on this summary we identify directions for further work. Finally, we present some ideas of how progress might be made in these directions

A framework for mathematics curricula in engineering education: a report of the mathematics working group.

This document adapts the competence concept to the mathematical education of engineers and explains and illustrates it by giving examples. It also provides information for specifying the extent to which a competency should be acquired. It does not prescribe a particular level of progress for competence acquisition in engineering education. There are many different engineering branches and many different job profiles with various needs for mathematical competencies; consequently it is not appropriate to specify a fixed profile. The competence framework serves as an analytical framework for thinking about the current state in one’s own institution and also as a design framework for specifying the intended profile. A sketch of an example profile for a practice-oriented study course in mechanical engineering is given in the document. This document retains the list of content-related learning outcomes (slightly modified) that formed the ‘kernel’ of the previous curriculum document. These are still important because lecturers teaching application subjects want to be sure that students have at least an ‘initial familiarity’ with certain mathematical concepts and procedures which they need in their application modelling. In order to offer helpful orientation for designing teaching processes, teaching and learning environments and approaches are outlined which help students to obtain the competencies to an adequate degree. It is clear that such competencies cannot be obtained by simply listening to lectures, so adequate forms of active involvement of students need to be included. Moreover, in a competence-based approach the mathematical education must be integrated in the surrounding engineering study course to really achieve the ability to use mathematics in engineering contexts. The document presents several forms of how this integration can be realized. This integration is essential to the development of competencies and will require close co-operation between mathematics academics and their engineering counterparts. Finally, since assessment procedures determine to a great extent the behaviour of students, it is extremely important to address competency acquisition in assessment schemes. Ideas for doing this are also outlined in the document. The main purpose of this document is to provide orientation for those who set up concrete mathematics curricula for their specific engineering programme, and for lecturers who think about learning and assessment arrangements for achieving the intended level of competence acquisition. It also serves as a framework for the group’s future work and discussions

Revision history aware repositories of computational models of biological systems

<p>Abstract</p> <p>Background</p> <p>Building repositories of computational models of biological systems ensures that published models are available for both education and further research, and can provide a source of smaller, previously verified models to integrate into a larger model.</p> <p>One problem with earlier repositories has been the limitations in facilities to record the revision history of models. Often, these facilities are limited to a linear series of versions which were deposited in the repository. This is problematic for several reasons. Firstly, there are many instances in the history of biological systems modelling where an 'ancestral' model is modified by different groups to create many different models. With a linear series of versions, if the changes made to one model are merged into another model, the merge appears as a single item in the history. This hides useful revision history information, and also makes further merges much more difficult, as there is no record of which changes have or have not already been merged. In addition, a long series of individual changes made outside of the repository are also all merged into a single revision when they are put back into the repository, making it difficult to separate out individual changes. Furthermore, many earlier repositories only retain the revision history of individual files, rather than of a group of files. This is an important limitation to overcome, because some types of models, such as CellML 1.1 models, can be developed as a collection of modules, each in a separate file.</p> <p>The need for revision history is widely recognised for computer software, and a lot of work has gone into developing version control systems and distributed version control systems (DVCSs) for tracking the revision history. However, to date, there has been no published research on how DVCSs can be applied to repositories of computational models of biological systems.</p> <p>Results</p> <p>We have extended the Physiome Model Repository software to be fully revision history aware, by building it on top of Mercurial, an existing DVCS. We have demonstrated the utility of this approach, when used in conjunction with the model composition facilities in CellML, to build and understand more complex models. We have also demonstrated the ability of the repository software to present version history to casual users over the web, and to highlight specific versions which are likely to be useful to users.</p> <p>Conclusions</p> <p>Providing facilities for maintaining and using revision history information is an important part of building a useful repository of computational models, as this information is useful both for understanding the source of and justification for parts of a model, and to facilitate automated processes such as merges. The availability of fully revision history aware repositories, and associated tools, will therefore be of significant benefit to the community.</p

CellML metadata standards, associated tools and repositories

The development of standards for encoding mathematical models is an important component of model building and model sharing among scientists interested in understanding multi-scale physiological processes. CellML provides such a standard, particularly for models based on biophysical mechanisms, and a substantial number of models are now available in the CellML Model Repository. However, there is an urgent need to extend the current CellML metadata standard to provide biological and biophysical annotation of the models in order to facilitate model sharing, automated model reduction and connection to biological databases. This paper gives a broad overview of a number of new developments on CellML metadata and provides links to further methodological details available from the CellML website

Informal leadership: A study of the impact of leadership on patient satisfaction in hospitals

The following non-experimental quantitative study was conducted in the context of an acute care hospital, surveying almost 4,000 registered nurses across 14 hospitals. The study had two primary objectives: the first utilized a two-sample t-test to determine if there was a statistically significant difference in job satisfaction and years of professional experience for those identified as informal leaders and those not identified as informal leaders. In both cases the study found a statistically significant relationship. Second, the study performed regression analysis to assess the relationship between registered nurses that were as informal leaders and patient satisfaction. Additionally, the study further assessed the impact of leadership style of the informal leader, specifically studying the impact of transactional, transformational, and passive-avoidant leadership tendencies on patient satisfaction. In this case, the study was unable to identify a statistically significant relationship between informal leadership and patient satisfaction. Similarly, the study was unable to identify a statistically significant relationship between transactional, transformational, and passive-avoidant leadership tendencies of the informal leaders and patient satisfaction. The study found that informal leaders tend to have more experience and a higher job satisfaction than their peers who were not identified as informal leaders. While failing to demonstrate a relationship between informal leadership and patient satisfaction, the study opens the door for future studies that can further assess the impact of the informal leader as a means of accomplishing important organizational outcomes. Key words: informal, emergent, leadership, transformational, transactional, passive-avoidant, nursing, patient satisfaction, outcom
