A new low profile antenna with improved performance for satellite on-the-move communications

A novel design solution for a low-profile fullduplex Satellite-On-The-Move Communications hybrid scanned phased array antenna for low elevation angle coverage (down to 10°) is described. The antenna is operated at Ku-Band. The unique louvered array element geometry in combination with a spatial filter/ “ray bending” lens facilitates the shaping of the element pattern to increase gain at low elevation angles. Preliminary modelling results using simple ray-tracing and 3D E simulation indicate that the desired low angle coverage can be achieved

Towards "a good enough justice" : Gillian Rose, interpretive systemology, and the mandatory introduction of British values in schools

Interpretive systemology is a systems approach asking researchers to explore different interpretations of a given social phenomenon or policy problem. While most systems approaches seek to support systemic intervention for social change, interpretive systemologists are mostly sceptical of interventions because they involve finding accommodations between stakeholders with different perspectives. It is these accommodations that allow people to define mutually-acceptable ways forward for organisations, communities or wider society, but this generally involves closing off critique so action can be taken. Instead of accommodation, interpretive systemologists value critique, and they see accommodation and critique as logically opposed.This thesis acknowledges that, in the context of social policy, accommodation and critique are necessarily in tension, but it challenges the idea that they are logically opposed. Therefore, the thesis reconstructs some of the theory underpinning interpretive systemology so that it becomes meaningful to relate accommodation and critique together in research projects.This reconstruction is achieved by drawing on the sociology of Gillian Rose, who examines what happens when a methodology prioritises critique over all other principles. She explains that this compromises any possibility of a positive normativity (a set of values or a pathway for action that people can commit to) because only negative normativity (overthrowing existing commitments through critique) is valorised. Rose also argues that we can work with concepts in tension (like accommodation and critique, or ethics and law) by acknowledging a ‘broken middle’ between them. The task of social policy is to continually work in the broken middle, knowing that it can never be mended, just navigated in practice when the two concepts in tension present decision makers with difficult dilemmas. This idea allows us to recalibrate the relationship between accommodation and critique in interpretive systemology, and the thesis argues that this recalibration is especially useful for analysing processes of marginalisation and conflict during policy interventions.The reconstructed methodology of interpretive systemology is then applied to a study of the UK Government’s 2014 policy that all schools must teach and uphold Fundamental British Values (FBVs). The existing literature on the FBVs reveals a diversity of perspectives, each grounded in different (mostly undeclared) assumptions about wider society. The methodology supports an explicit examination of the broader societal and institutional contexts that made the 2014 policy meaningful in different ways to various stakeholders: specifically, it enables the exploration of different understandings of how the FBVs generate or undermine the institutional preconditions for practical discourse in a manner that accommodates moral diversity within a liberal institutional framework. Three interpretations are provided: two competing liberal perspectives (realism and multiculturalism) and a somewhat-marginalized religious perspective, drawing on elements of Christian and Islamic theology. Although all three interpretations have some shortcomings in terms of their implications for social policy, the thesis argues that aspects of the theological interpretation offer the best prospect of working in the broken middle between accommodation and critique. This is because it embraces a reflexive notion of transformative accommodation, which signals the need for an emergent accommodation responding to critiques of the bi-partisan liberal mainstream and their explicit or implicit emphasis on transformative constitutionalism. Essentially, the idea of transformative accommodation requires critique as much as accommodation.The insights from the use of the reconstructed interpretive systemology are compared back to the insights in the prior literature on the FBVs to demonstrate the added value that the methodology offers to social policy analysis

A low profile radiating element with nearly hemispheric coverage for satellite communications on-the-move hybrid array antenna

A novel design solution of a dual-linearly polarised Ku-band low-profile radiating element for low elevation angle coverage (down to 10° above horizon) is presented. Such an element is suitable for full-duplex Satellite Communications On-The-Move (SCOTM) hybrid scanned phased array antenna applications. Standard designed radiating elements for array applications with low profile physical structure suffer poor low elevation angle coverage as the element pattern reduces by sine of the elevation angle. The element design demonstrated in this paper features unique louvered array element geometry incorporating a spatial “ray bending” lens facilitates the shaping of the element pattern to increase gain at low elevation angles. Preliminary modelling results using ray tracing analysis shows that the desired low angle coverage can be achieved. Currently in progress full 3D electromagnetic simulations which include the interaction between the basic radiator and the spatial lens indicates that using an ideal tilted element with novel louvered reflector in addition with proposed lens, low angular coverage can potentially be realised in a low profile structure

Current knowledge and recent advances in understanding metabolism of the model cyanobacterium Synechocystis sp. PCC 6803

Cyanobacteria are key organisms in the global ecosystem, useful models for studying metabolic and physiological processes conserved in photosynthetic organisms, and potential renewable platforms for production of chemicals. Characterising cyanobacterial metabolism and physiology is key to understanding their role in the environment and unlocking their potential for biotechnology applications. Many aspects of cyanobacterial biology differ from heterotrophic bacteria. For example, most cyanobacteria incorporate a series of internal thylakoid membranes where both oxygenic photosynthesis and respiration occur, while CO2 fixation takes place in specialised compartments termed carboxysomes. In this review, we provide a comprehensive summary of our knowledge on cyanobacterial physiology and the pathways in Synechocystis sp. PCC 6803 (Synechocystis) involved in biosynthesis of sugar-based metabolites, amino acids, nucleotides, lipids, cofactors, vitamins, isoprenoids, pigments and cell wall components, in addition to the proteins involved in metabolite transport. While some pathways are conserved between model cyanobacteria, such as Synechocystis, and model heterotrophic bacteria like Escherichia coli, many enzymes and/or pathways involved in the biosynthesis of key metabolites in cyanobacteria have not been completely characterised. These include pathways required for biosynthesis of chorismate and membrane lipids, nucleotides, several amino acids, vitamins and cofactors, and isoprenoids such as plastoquinone, carotenoids, and tocopherols. Moreover, our understanding of photorespiration, lipopolysaccharide assembly and transport, and degradation of lipids, sucrose, most vitamins and amino acids, and heme, is incomplete. We discuss tools that may aid characterisation of cyanobacterial metabolism, notably CyanoSource, a barcoded library of targeted Synechocystis mutants, which will significantly accelerate characterisation of individual proteins

mSpace: improving information access to multimedia domains with multimodal exploratory search

Overview of mSpace interaction approach for presenting exploratory search particularly in the audio domain by using slices, preview cues, and user-determined organization of information from high-dimensional space

mSpace Mobile: Exploring Support for Mobile Tasks

In the following paper we compare two Web application interfaces, mSpace Mobile and Google Local in supporting location discovery tasks on mobile devices while stationary and while on the move. While mSpace Mobile performed well in both stationary and mobile conditions, performance in Google Local dropped significantly. We postulate that mSpace Mobile performed so well because it breaks the paradigm of the page for delivering Web content, thereby enabling new and more powerful interfaces to be used to support mobility

mSpace Mobile: a UI Gestalt to Support On-the-Go Info-Interaction

mSpace Mobile Interaction presents a UI gestalt of 7 techniques for mobile/on-the-move information retrieval and assessment that enables multiple views of the information within a persistent focus+context viewer. It uses the web but breaks the web page paradigm to support effective rapid triage

THE ROLE OF ECTOMYCORRHIZAL FUNGI ON FERTILIZED AND UNFERTILIZED NURSERY GROWN WHITE SPRUCE

Nursery grown seedlings are an essential part of the forestry industry. These seedlings are grown under high nutrient conditions caused by fertilization. Though grown in a controlled environment, symbionts such as ectomycorrhizal fungi (EcMF) are often found in these conditions. To examine the effects of EcMF in these conditions, colonized Picea glauca seedlings were collected from Toumey Nursery in Watersmeet, MI. After collection, the EcMF present were morphotyped, and seedlings with different morphotypes were divided equally into two treatment types- fertilized and unfertilized. Seedlings received treatment for one growing season. After that time, seedlings were collected, ectomycorrhizas identified using morphotyping and DNA sequencing, and seedlings were analyzed for differences in leaf nutrient concentration, content, root to shoot ratio, total biomass, and EcMF community structure. DNA sequencing identified 5 unique species groups- Amphinema sp. 1, Amphinema sp. 5, Thelephora terrestris, Sphaerosporella brunnea, and Boletus variipes. In the unfertilized treatment it was found that Amphinema sp. 1 strongly negatively impacted foliar N concentration. In fertilized seedlings, Thelephora terrestris had a strong negative impact on foliar phosphorus concentration, while Amphinema sp. 1 positively impacted foliar boron, magnesium, manganese, and phosphorus concentration. In terms of content, Amphinema sp. 1 led to significantly higher content of manganese and boron in fertilized treatments, as well as elevated phosphorus in unfertilized seedlings. Amphinema sp. 5 had a significant negative effect on phosphorus content. When examining root to shoot ratio and biomass, those seedlings with more non-mycorrhizal tips had a higher root to shoot ratio. Findings from the study shed light on the interactions of the species. Amphinema sp. 5 shows very different functionality than Amphinema sp. 1. Amphinema sp. 1 appears to have the highest positive effect on seedling nutrition when in both fertilized and unfertilized environments. Amphinema sp. 5 and T. terrestris appear to behave parasitically in both fertilized and unfertilized conditions

An experience of modularity through design

We aim to utilise the experiences of a marine industry-based design team to determine the need for research into a modular design methodology in an industrial environment. In order to achieve this we couple the outcome of a current design project with the findings of a recent literature survey with the objectives of firstly, clarifying why a methodology is required and, secondly, defining the key elements which the methodology would have to realise or address. The potential benefits of modularity have long been recognised in the shipbuilding industry. Many shipbuilders adopt a 'module' approach to ship construction whereby the ship structure is separated into a number of large structural 'blocks' to ease manufacture and manoeuvrability during construction. However, as understanding of the capabilities of modularity as a design tool develops there is increased interest in capitalising on the differing life phase benefits of modularity such as reduced design costs and time, increased ease of maintenance, upgrade, re-use, redesign and standardisation across individual products and product families. This is especially pertinent in naval shipbuilding where the maintenance of a class of ship requires that all previously designed ships in that class must be of similar outfitting and must be able to interface with the new ship, in terms of propulsion, weapons, communications and electronics, and thus often require some form of retrofit. Therefore, many shipbuilders are moving from viewing modularity as a purely 'manufacturing' principle to a design centred principle. However, as noted by Chang and Ward 'none of the design theories or tools in the mechanical world serves as an articulate procedure for designers to follow in practising modular design'. Thus, despite the identification of a need to introduce modular principles at an earlier stage than detail design and construction, there is little aid in the form of tools, techniques and methodologies for designers in practice

The moral space in entrepreneurship: an exploration of ethical imperatives and the moral legitimacy of being enterprising.

This paper explores the morality associated with entrepreneurship. It has been argued that there is no moral space in entrepreneurship, but such instrumental views may miss out much of the nature of enterprise and how it is understood. Consequently we propose that a socially-constructed perspective, based upon the meanings of entrepreneurship, may help to understand the morality of entrepreneurship. By applying such a lens, we find that the narratives and discourses of the meanings of entrepreneurship are ideological and clearly present a moral space. This space lies between the individual and society and is normatively articulated in entrepreneurial discourses. We develop a tentative framework which links values and outcomes that shows how 'authenticated' entrepreneurship, that is to say that which resonates with a socially approved moral dimension, is legitimized by comparisons with the socially constructed view. The empirical part of the paper comprises of two case stories. The first is a local garage owner who has a reputation as a decent man; the second is a notorious, but entrepreneurial London gangster. Our analysis shows that to be judged 'entrepreneurial', it is not enough to act entrepreneurially; the social constructs of public perceptions entail examining both moral means and moral ends. We conclude that there is a moral imperative in entrepreneurship
