Have a question? Just ask it: using an anonymous mobile discussion platform for student engagement and peer interaction to support large group teaching

This article analyses the pilot of an anonymous question and answer mobile appli-cation with a large cohort of undergraduate students (460) enrolled on an Opera-tions Strategy Management module. The mobile application allowed students to pose anonymous questions to both peers and staff, create replies and vote on ques-tions posted by other users. The aim of the pilot was to evaluate how this applica-tion could be used to enhance communication, engagement and student learning both inside and outside of class time to overcome some of the challenges presented by large cohort teaching. An initial evaluation was undertaken exploring both the analytics attached to the platform and a thematic analysis of the posts. The initial findings of the pilot were positive, with the majority of students installing and reg-ularly accessing the application with use increasing over time. The questions posed demonstrated engagement beyond surface-level memorisation of module content, and there were indications that the application could be beneficial in supporting student community awareness and interaction within large cohorts

Diffusion of process improvement methods in European SMEs

Purpose: The purpose of this paper is to evaluate the European Regions for Innovative Productivity project that established Innovative Productivity Centres (IPCs) to assist SMEs in the North Sea Region of Europe to develop a process improvement capability. A conceptual framework explains how a process improvement methodology developed for large firms was adapted and shaped to meet the needs of SMEs. Design/methodology/approach: A comparative case study of 23 SMEs within six European countries. A protocol was developed to collect financial and operational data. This was supplemented by observations, secondary data and field notes. An established research model was used to evaluate the effectiveness and impact of the process improvement interventions. Findings: The intervention context and structure of the IPCs varied by country which shaped process improvement interventions at two levels: the country and the firm. During diffusion three process improvement variants emerged that were tailored to fit the local context. Developing a process improvement capability depended upon the availability of company resources, establishing KPIs and change agent support. Originality/value: The research contributes to knowledge and theory on diffusion and institutionalization by examining how SMEs responded to institutional pressures by implementing process improvement practices in different ways. Heterogeneity of both the IPCs and the external change agents were the drivers in shaping the improvement practices

Mitigation of atmospheric perturbations and solid Earth movements in a TerraSAR-X time-series

The TerraSAR-X (TSX) synthetic aperture radar (SAR) marks the recent emergence of a new generation of spaceborne radar sensors that can for the first time lay claim to localization accuracies in the sub-meter range. The TSX platform's extremely high orbital stability and the sensor's hardware timing accuracy combine to enable direct measurements of atmospheric refraction and solid Earth movements. By modeling these effects for individual TSX acquisitions, absolute pixel geolocation accuracy on the order of several centimeters can be achieved without need for even a single tiepoint. A 16-month time series of images was obtained over a fixed test site, making it possible to validate both an atmospheric refraction and a solid Earth tide model, while at the same time establishing the instrument's long-term stability. These related goals were achieved by placing trihedral corner reflectors (CRs) at the test site and estimating their phase centers with centimeter-level accuracy using differential GPS (DGPS). Oriented in pairs toward a given satellite track, the CRs could be seen as bright "points” in the images, providing a geometric reference set. SAR images from the high-resolution spotlight (HS) mode were obtained in alternating ascending and descending orbit configurations. The highest-resolution products were selected for their small sample dimensions, as positions can be more precisely determined. Based on the delivered product annotations, the CR image positions were predicted, and these predictions were compared with their measured image positions both before and after compensation for atmospheric refraction and systematic solid Earth deviations. It was possible to show that when the atmospheric distortion and Earth tides are taken into account, the TSX HS products have geolocation accuracies far exceeding the specified requirements. Furthermore, this accuracy was maintained for the duration of the 16-month test period. It could be demonstrated that with a correctly calibrated sensor, and after accounting for atmospheric and tidal effects, tiepoint-free geolocation is possible with TSX with an absolute product accuracy of about 5c

‘Are they out to get us?’ Power and the ‘recognition’ of the subject through a ‘lean’ work regime

Critical studies of ‘lean’ work regimes have tended to focus on the factory shop floor or public and healthcare sectors, despite its recent revival and wider deployment in neoliberal service economies. This paper investigates the politics of the workplace in a United Kingdom automotive dealership group subject to an intervention inspired by lean methods. We develop Foucauldian studies of governmentality by addressing lean as a technology of power deployed to act on the conduct of workers, examining how they debunk, distance themselves from and enact its imperatives. Our findings support critiques of lean work regimes that raise concerns about work intensification and poor worker health. Discourses of professional autonomy allow workers to distance themselves from lean prescriptions, yet they are reaffirmed in their actions. More significantly, we illustrate the exercise of a more encompassing form of power, showing how lean harnesses the inherently exploitable desire for recognition among hitherto marginalised workers, and its role as a form of ‘human capital’. The paper contributes to critical studies of lean by illustrating its subtle, deleterious and persistent effects within the analytical frame of neoliberal governmentality. We also demonstrate how studies of governmentality can be advanced through the analysis of contested social relations on the ground, highlighting the ethico-political potential of Foucauldian work

A framework for promoting learning in IS design and implementation

Purpose The purpose of this paper is to set out an argument for a way to design, implement and manage IS with an emphasis on first, the learning that can be created through undertaking the approach, and second, the learning that may be created through using the IS that was implemented. The paper proposes joining two areas of research namely, technology management with soft systems methodology (SSM). The framework was developed through undertaking a customer concern management project within a manufacturing organisation. Design/methodology/approach Reviewing the literature on information systems management, the learning organisation, and systems theory a proposed synergy is found. The outcome of this synergy allows a number of methodologies to be identified that are argued as suitable for IS design. From these information system development (ISD) methodologies, SSM is expanded to incorporate the principles of the learning organisation and systems theory. The expanded SSM framework is applied in practice through a process of participatory action research. Findings The outcome of the practical work argues for a complete framework that joins the areas of research (SSM and technology management) and emphasises other thinking from the areas of systems theory and the “learning organisation”. Research limitations/implications The paper concludes with a discussion on the advantages of joining soft systems with technology management but also the limitations created. Such limitations have been identified as moving from the soft, tacit issues of the design phases to the harder more structured aspects of technology implementation and management. A change in philosophy may restrict other issues from being explored. This issue needs to be focussed on in future research. Practical implications A framework has been developed that draws on the work of soft systems methodology (SSM) and a technology management process framework (TMPF) used in the area of technology management. By expanding the SSM model and joining it with the TMPF an attempt to give individuals and teams a practical tool to help design, implement, and manage IS with an emphasis on learning the framework promotes. Originality/value The framework provides advantages for academics, consultants and other practitioners and gives a central focus on what issues need to be accomplished more explicitly in order to undertake an ISD project

Investigating the risks of Covid-19 vaccine supply chain

The development of the Covid-19 vaccines is promising to end the pandemic. However, having a safe and efficacy vaccine is one thing, ensuring them get delivered is quite another. The ‘Great Lockdown’ has not only largely restricted the movement of people and goods, but also caused significant impacts on the delivery of PPEs and other healthcare products. This study aims to understand how supply chains can mirror the demand for Covid-19 vaccinations. It employs the Protection Motiving Theory to investigate the relationships between participants’ information on vaccine availability and their decisions on vaccine uptake

In-depth verification of Sentinel-1 and TerraSAR-X geolocation accuracy using the Australian Corner Reflector Array

This article shows how the array of corner reflectors (CRs) in Queensland, Australia, together with highly accurate geodetic synthetic aperture radar (SAR) techniques—also called imaging geodesy—can be used to measure the absolute and relative geometric fidelity of SAR missions. We describe, in detail, the end-to-end methodology and apply it to TerraSAR-X Stripmap (SM) and ScanSAR (SC) data and to Sentinel-1interferometric wide swath (IW) data. Geometric distortions within images that are caused by commonly used SAR processor approximations are explained, and we show how to correct them during postprocessing. Our results, supported by the analysis of 140 images across the different SAR modes and using the 40 reflectors of the array, confirm our methodology and achieve the limits predicted by theory for both Sentinel-1 and TerraSAR-X. After our corrections, the Sentinel-1 residual errors are 6 cm in range and 26 cm in azimuth, including all error sources. The findings are confirmed by the mutual independent processing carried out at University of Zurich (UZH) and German Aerospace Center (DLR). This represents an improve�ment of the geolocation accuracy by approximately a factor of four in range and a factor of two in azimuth compared with the standard Sentinel-1 products. The TerraSAR-X results are even better. The achieved geolocation accuracy now approaches that of the global navigation satellite system (GNSS)-based survey of the CRs positions, which highlights the potential of the end-to-end SAR methodology for imaging geodesy

Spaceborne SAR product geolocation accuracy: A Sentinel-1 update

Sentinel-1A (S1A), launched by the European Space Agency (ESA) on April 3, 2014, is a state-of-the-art spaceborne Synthetic Aperture Radar (SAR) Earth observation platform. S1A products are expected to provide high and consistent geolocation accuracy. As of the end of May, 2014, the satellite has not yet reached its reference orbit. However, estimation of product geolocation accuracy is ongoing, and improvements are continually being made. The results reported here represent the early situation, with continued progress expected

Biodiversity conservation and utilisation in the Maltese Islands

The Maltese archipelago which occupies an area of c.316km2 consists of the inhabited islands of Malta, Gozo and Comino and several other uninhabited islets and rocks. In spite of their restricted area, the limited number of habitats, and the intense human pressure, the Maltese Islands support a very diverse terrestrial and freshwater biota, with some 2000 species of plants and fungi known, more than 4000 species of insects, several hundred species of other invertebrates, and more than 200 terrestrial or freshwater vertebrates; of these c.80 taxa are considered as endemic. The most characteristic terrestrial ecosystems are those represented by the Mediterranean scrubland, of which the maquis, garigue and steppe are the main types present - evergreen woodlands are all but extinct and only four relict patches occur. Minor terrestrial ecosystems include rupestral, freshwater and coastal communities including sand dunes, saline marshlands and rocky coasts. Marine communities include those characteristic of both hard and mobile substrata. Human impact is significant, and human influence is a key feature of the islands' ecology. In fact, the population density is the highest in Europe and built-up areas have increased from 5 to 16% in the past 30 years. Some 38% is agricultural land and 46% of the area is undeveloped, but even so, no wilderness areas remain in the Maltese Islands. The management practices of the islands include mainly those concerned with agriculture, animal husbandry and herding, and the use of fire, which all proved to be detrimental to the local biota, mainly through habitat destruction, the removal of competing species and the introduction of alien ones, particularly goats, rabbits and sheep. All these human activities have put great stress on the Maltese biodiversity, with a consequent impoverishment of the flora and fauna. Flora and fauna which are directly or indirectly exploited in the Maltese Islands are reviewed. Work on biodiversity carried out by national institutions, government departments, agencies and non-governmental organisations is also outlined. Legislation safeguarding biodiversity is relatively new to Malta. Prior to the Environment Protection Act [EPA] (1991), and the Development Planning Act [DPA] (1992), legislation mainly protected species due to their associated economic importance. Both the EPA and DPA have permitted the creation of protected areas. The EPA also protects some of the flora and fauna, including some 10% of the endemics. The DPA, on the other hand incorporates the Structure Plan for the Maltese Islands which is a strategic plan meant to harmonise development with conservation. On the international level, Malta is party to the Washington Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) which is implemented locally by means of regulations controlling trade in species of flora and fauna (1992). Malta is also party to the Ramsar Convention, the Berne Convention, the Barcelona Convention, the Convention on Biological Diversity, and the Law of the Sea Convention.peer-reviewe

SHRiMP: Accurate Mapping of Short Color-space Reads

The development of Next Generation Sequencing technologies, capable of sequencing hundreds of millions of short reads (25–70 bp each) in a single run, is opening the door to population genomic studies of non-model species. In this paper we present SHRiMP - the SHort Read Mapping Package: a set of algorithms and methods to map short reads to a genome, even in the presence of a large amount of polymorphism. Our method is based upon a fast read mapping technique, separate thorough alignment methods for regular letter-space as well as AB SOLiD (color-space) reads, and a statistical model for false positive hits. We use SHRiMP to map reads from a newly sequenced Ciona savignyi individual to the reference genome. We demonstrate that SHRiMP can accurately map reads to this highly polymorphic genome, while confirming high heterozygosity of C. savignyi in this second individual.
