Experimenting with Realism in Software Engineering Team Projects: An Experience Report

Over Several years, we observed that our students were sceptical of Software Engineering practices, because we did not convey the experience and demands of production quality software development. Assessment focused on features delivered, rather than imposing responsibility for longer term `technical debt'. Academics acting as 'uncertain' customers were rejected as malevolent and implausible. Student teams composed of novices lacked the benefits of leadership provided by more experienced engineers. To address these shortcomings, real customers were introduced, exposing students to real requirements uncertainty. Flipped classroom teaching was adopted, giving teams one day each week to work on their project in a redesigned laboratory. Software process and quality were emphasised in the course assessment, imposing technical debt. Finally, we introduced a leadership course for senior students, who acted as mentors to the project team students. This paper reports on the experience of these changes, from the perspective of different stakeholders

Formalising responsibility modelling for automatic analysis

Modelling the structure of social-technical systems as a basis for informing software system design is a difficult compromise. Formal methods struggle to capture the scale and complexity of the heterogeneous organisations that use technical systems. Conversely, informal approaches lack the rigour needed to inform the software design and construction process or enable automated analysis. We revisit the concept of responsibility modelling, which models social technical systems as a collection of actors who discharge their responsibilities, whilst using and producing resources in the process. Responsibility modelling is formalised as a structured approach for socio-technical system requirements specification and modelling, with well-defined semantics and support for automated structure and validity analysis. The effectiveness of the approach is demonstrated by two case studies of software engineering methodologies

Luminescence investigations at Quendale (Broo Peninsula, Shetland)

This report is concerned with optically stimulated luminescence (OSL) investigations of sediment samples collected from ongoing University of Southern Maine archaeological excavations at the Links of Quendale, southern Shetland, investigating the early-modern township of Broo. 11 sediment samples were submitted to the luminescence laboratory at SUERC for OSL dating by Ian Simpson. This report summaries the protocols, and laboratory analysis, employed in quartz single aliquot regenerative (SAR) OSL dating, as used to construct an OSL chronology for wind-blown sands in proximity to the Broo excavations, in association with archaeological structures (5 samples), and for sands in the coastal and inland dune systems (6 samples). The chronology established for the inland sands, in contexts associated with the Broo 2 building and enclosure, spans from AD1540 ± 40 (SUTL2441) through to AD1810 ± 25 (SUTL2519), encompassing the archaeological period of interest. The dates obtained for sands within the enclosed and unenclosed areas to the immediate east and southwest of the excavated Broo site, are AD1760 ± 30 - AD1760 ± 25, and AD1810 ± 25 (SUTL2517-2518 and 2519, respectively), are consistent with the expectation that the clean sands which infill these structures, post-date the period in which the Broo township was abandoned. The coastal sand accumulations, as so far dated, yielded luminescence ages of 2380 ± 230 BC (SUTL2526), 1510 ± 270 BC (SUTL2527), AD 1030 ± 80 (SUTL2528), AD 1690 ± 50 (SUTL2529), AD 1720 ± 20 (SUTL2530) and a mixed-age sample with youngest component at AD 1955 ± 15 (SUTL2531), implying periods of sand mobilisation, synchronous with sand deposition in Orkney and northern Scotland, in the late Neolithic, the Early Bronze Age, the Norse period, the early-modern, and modern periods. This work suggests that the present-day physio-geographical setting of the Quendale Links, comprised of the coastal sand barrier, and the inland dune fields, is a product of a prolonged history of sand mobilisation, erosion and deposition from the Neolithic to the present day. Furthermore, the emerging temporal framework, coupled with the spatial distribution of dune forms across the Links, raises questions as to whether Little Ice Age storms were responsible for deposition, or erosive destruction of older dune-forms, and the re-mobilisation of this sediment. To test these ideas, profiling methods, both field- and laboratory- based, could be employed to obtain a more complete temporal and spatial characterisation of the dune systems and excavated sequences. Further OSL sampling and dating would be needed to define the vertical and lateral chronostratigraphies of the environmental features in the landscape and their relationships to archaeological structures

The Institutional Repository route to Open Access: implications for its evolution

Open access to peer reviewed journal articles is one of the key messages of the current global movement that is changing the paradigm of scholarly communication. Creating open access journals is one such route and creating institutional repositories containing author generated electronic text is another complementary alternative. In the UK, the FAIR (Focus on Access to Institutional Resources) programme of research is based on the vision of open access. Experiments in setting up an institutional repository for academic research output at the University of Southampton have emphasized that the institutional repository agenda is broader and that academic needs may dictate a more expanded database model than the pioneering discipline based e-Prints archive known as ‘arXiv’. The institution is represented by a broad range of publication types including, but not exclusively, peer reviewed journal articles and the different disciplines have evolved different recording practices. Full text deposits may provide the opportunity for added value elements – e.g. enhanced diagrams, additional data or presentations – if the database provides the capability. The repository may provide the building blocks for effective management of collaborative e-research. Academic institutions that impose research reporting in an institutional repository require full recording of publications including those where obtaining full text is difficult or inappropriate. A practical route is, therefore, to develop an institutional repository which is ’hybrid’ – containing both records and full text where achievable. In this scenario, the technical and management issues eg authentication and quality assurance of the metadata generation may become more complex. However, the full text element can grow as the practice becomes more natural within the recording process and as copyright restrictions ease. In the UK, several factors including the Research Assessment Exercise and citation impact measures based on increasing open access could also help encourage this change. The goal of providing open access to peer reviewed research items may, therefore, come about by a more circuitous but, in the end, more effective route. The ‘hybrid’ library will have evolved to the digital library of the ideal

‘Missing the Target’ – A Critical Examination of Policy Frameworks for Aboriginal and Torres Strait Islander Inclusion into the Allied Health Professions

Objective This paper focuses on critically examining the inclusion of Aboriginal and Torres Strait Islander people in policy frameworks by regulatory health peak bodies against the backdrop of the Government’s response to the Closing the Gap (2020) report. Method Websites of ten allied health professional bodies were searched and analysed as policy as text. Results Of the ten professions examined, the search strategy identified 9 professions were signatories or co-signatories on Reconciliation Action Plans (RAP) and three professions made mention of Aboriginal and Torres Strait Islander equity strategies to enter the profession as part of accreditation standards. Conclusions Professional bodies were found to use discourses of recognition in the inclusion of Aboriginal and Torres Strait Islander students with reference to the development of measurable accountabilities in the future. Implications The contested value of setting targets to generate meaningful action by policy players is likely to restrict momentum in this space

Third-party verifiable voting systems: addressing motivation and incentives in e-voting

Voter-verifiable voting systems place significant demands of both effort and knowledge onto ordinary voters who have only limited incentives to participate. We suggest the use of third-party verifiable voting systems, harnessing the very strong incentives for candidates and observers to verify that votes are correctly counted. A generic modification enabling this via the use of pre-filled ballots and secure depositing is outlined and we demonstrate this modification by applying it to two major voter-verifiable voting systems. Additionally, potential vulnerabilities of this approach are discussed

Beware the painful nerve palsy; neurostenalgia, a diagnosis not to be missed

We present a case of painful radial nerve palsy following application of a humeral lengthening frame. At re-operation, the radial nerve was found to be compressed against a distal pin. This was re-sited providing immediate pain relief and a gradual resolution of the radial nerve palsy. Pain in association with a nerve palsy should alert the clinician to the possibility of nerve compression that may benefit from urgent decompression

Geochronologies from the Kathmandu Valley UNESCO World Heritage Site: Optically Stimulated Luminescence measurement of monument foundation sediments and radiocarbon measurement of timbers

Nepal was struck by two major earthquakes on the 25th April and the 12th May 2015, which devastated large areas of the county, with substantial loss of life and livelihoods, and destroying both rural and urban infrastructure and property. The earthquakes and associated aftershocks damaged and destroyed much of Nepal’s unique cultural heritage, including monuments within the Kathmandu Valley’s UNESCO World Heritage Site of Universal Outstanding Value. These damaged monuments are currently subject to a major program of consultation, reconstruction and conservation. As part of this, geoarchaeological investigations are underway on the foundation sediments of the collapsed monuments within the damaged Durbar Squares of Hanuman Dhoka and Bhaktapur and the temple complex of Pashupati. This report summaries: a) the OSL investigations on foundation sediments to the Changu Narayan and Vatsala Temples (Bhaktapur) and Jaisideval, Kathamandap, Pashupati and Trailokya Mohan Temples (Kathmandu; Table 1).; b) the radiocarbon measurements from timbers salvanged from the Kasthsmandap monument

Using Poultry Manure From Layers as a Supplemental Nitrogen Source for Corn

The objectives of this study were to try to find an effective inorganic nitrogen (N) fertilizer rate to apply to a corn crop when poultry manure has been used on the field and to see if an N soil test at sidedress time could help predict the amount of N needed

Residents Informing the Planning Process: Pleasant Valley and Its Natural Resources

As a society, we are slowly learning the importance of the interaction between the natural and built environments. We need a new model for planning and development that gives more weight to natural resource considerations than has traditionally occurred in the development process. An opportunity exists in Pleasant Valley to bring focus to natural resources in future planning efforts by tapping into the local knowledge of residents who know and love the land. Because the area will begin to urbanize in the near future, it is necessary to learn about the area before development occurs or people move away. The purpose of this project was to gather the local knowledge of natural resources and distill it into key findings to guide future plans
