High Rate Discharge Studies of LI/SO2 Batteries

A battery composed of twelve lithium/sulfur dioxide D size cells in series is forced discharged at 21 amperes. This current is established by the proposed use of the battery and represented a discharge condition which might produce venting. Discharge of the battery into voltage reversal results not only in cells venting but also in the violent rupture of at least one cell

Double Exponential Instability of Triangular Arbitrage Systems

If financial markets displayed the informational efficiency postulated in the efficient markets hypothesis (EMH), arbitrage operations would be self-extinguishing. The present paper considers arbitrage sequences in foreign exchange (FX) markets, in which trading platforms and information are fragmented. In Kozyakin et al. (2010) and Cross et al. (2012) it was shown that sequences of triangular arbitrage operations in FX markets containing 4 currencies and trader-arbitrageurs tend to display periodicity or grow exponentially rather than being self-extinguishing. This paper extends the analysis to 5 or higher-order currency worlds. The key findings are that in a 5-currency world arbitrage sequences may also follow an exponential law as well as display periodicity, but that in higher-order currency worlds a double exponential law may additionally apply. There is an "inheritance of instability" in the higher-order currency worlds. Profitable arbitrage operations are thus endemic rather that displaying the self-extinguishing properties implied by the EMH.Comment: 22 pages, 22 bibliography references, expanded Introduction and Conclusion, added bibliohraphy reference

Determining the influence and effects of manufacturing variables on sulfur dioxide cells

A survey of the Li/SO2 manufacturing community was conducted to determine where variability exists in processing. The upper and lower limits of these processing variables might, by themselves or by interacting with other variables, influence safety, performance, and reliability. A number of important variables were identified and a comprehensive design experiment is being proposed to make the proper determinations

Let me entertain you: the ambivalent role of university lecturers as educators and performers

In England, higher education is more marketised than ever before as the difference between students and consumers is increasingly blurred, propelled by the rise in tuition fees. With students demanding more for their money, the role of university lecturers continues to change. This study explores the ways in which lecturers re-evaluate and reconstruct their roles and responsibilities in light of heightened student expectations. We draw on 30 in-depth interviews with lecturers from the social sciences, across two post-1992 universities in England, where tuition fees have tripled since 2012. We focus on lecturers’ views and experiences of student expectations, as well as the support available to students as we shift towards a more consumerist approach in higher education. We find examples of tension between academic values and consumeristic student expectations as lecturers discuss their precarious positions as an educator as well as an entertainer. We believe that the expanding role of lecturers merits an urgent review at the institutional and national level, to promote and ensure clarity of the boundaries and expectations of teaching staff

Furthering alternative cultures of valuation in higher education research

The value of higher education is often implicit or assumed in educational research. The underlying and antecedent premises that shape and influence debates about value remain unchallenged which perpetuates the dominant, but limiting, terms of the debate and fosters reductionism. I proceed on the premise that analyses of value are not self–supporting or self-referential but are embedded within prevailing cultures of valuation. I contend that challenging, and providing alternatives to, dominant narratives of higher education requires an appreciation of those cultures. I therefore highlight some of the existing cultures of valuation and their influence. I then propose Sayer’s concept of lay normativity as a culture of valuation and discuss how it translates into the practices of research into higher education, specifically the practice of analysis. I animate the discussion by detecting the presence of lay normativity in the evaluative space of the capability approach

Engaging with childhood: student placements and the employability agenda.

Employability is a particular organising narrative within the global, neoliberal economic discourse, with increasing relevance across different educational contexts. For universities in the UK, student employability, that is the readiness of students to gain and maintain employment and contribute to the economy, is a significant feature of accountability with employability outcomes increasingly used by students in making their decision of which university to attend. Yet little attention is paid to the organizing power of the employability agenda and to university students’ participation in that agenda apart from focussing on knowledge and skills relevant to gain employment. This is particularly concerning in university programmes that develop professionals who work with children. Placement, gaining knowledge, skills and experience in the places where children and young people are found, is a common aspect of employability being embedded within programme curricula. This article explores the organising power of the employability agenda for children and young people in a context of university placements. Focused on student experiences on placement in primary school settings in the north of England analysis considers students’ engagement with their own learning and the children who are essential to that learning

An assessment of the business impacts of the UK's Enterprise Capital Funds

Recent European studies present persistently critical views of the under performance of government backed venture capital (GVC) schemes when compared to their private sector counterparts. However, they assess the performance of outmoded funding models and fail to contextualise the economic development role of these schemes. This paper provides a contemporary assessment of the business impacts of the UK government’s flagship Enterprise Capital Funds (ECFs) VC scheme in addressing the sub-£2m equity finance gap facing young potential high growth businesses requiring investments. Supply and demand-side evidence is presented from interviews with ECF fund managers, alternative private VCs, industry experts and surveys of successful and unsuccessful scheme applicants. We find that, despite the limitations of mid-scheme evaluation, ECFs are addressing the UK equity gap and delivering business employment, revenue and innovation impacts. However, further progress is required in order to achieve optimal business exits and sustainable early stage private VC system impacts

Managerial Hubris, Trade-Associations, and Regulatory Knowledge in Micro-Firms

To avoid breaking the law for regulatory non-compliance, it is essential that micro-firm owner-managers are aware of deficiencies in their knowledge, so that they can seek improvement and avoid over-confidence (i.e. hubris) in their knowledge levels. Using newly collected survey data from micro-firms in the English accommodation sector and multivariate techniques, the authors explore the possibility of hubris by making a novel distinction between the Perceived-Knowledge and Actual-Knowledge of regulation held by micro-firm owner-managers. Both Perceived-Knowledge (from self-assessment) and Actual-Knowledge (from a simple test) over four core areas of regulation are found to be different, generally poor and suggestive of hubris. The relationship between these knowledge levels is further explored by considering the role of trade association membership (since they support members) and attitude (since it effects learning). Attitude is found to be positively associated with both forms of knowledge, while trade association memberships are also found to be associated with enhanced Perceived-Knowledge, but not Actual-Knowledge. In light of the results, the authors suggest several priority areas for improving Actual-Knowledge and self-assessment skills, and areas for future research.</p

Establishing a new UK finance escalator for innovative SMEs: the roles of the Enterprise Capital Funds and Angel Co-investment Fund

This paper examines UK public policy addressing the seed and early stage equity finance gap since the Global Financial Crisis (GFC). Drawing on lessons learned from recent studies of UK and international government equity schemes, two contemporary models of government backed equity finance are examined. The focus is on the Enterprise Capital Funds (ECFs) and the Angel Co-investment Fund (ACF), the UK government’s main schemes operating in the sub-£2m equity finance gap to address the capital requirements for developing the UK’s young, potential high growth businesses. The paper highlights the shortcomings of traditional interim fund performance analysis and presents current demand and supply side evidence that establishes that these schemes are making attributable impacts on their portfolio businesses and the wider UK economy. It also demonstrates that they are playing important roles in the establishment of a new post GFC UK finance escalator. However, whilst these schemes were found to be currently complementary and effective, their future roles within the UK’s evolving post GFC seed and early stage equity markets are also considered.

The potential of trading activity income to fund third sector organisations operating in deprived areas

In the United Kingdom, as in other countries, Third Sector Organisations (TSOs) have been drawn towards income sources associated with trading activities (Teasdale, 2010), but many remain reliant on grant funding to support such activities (Chell, 2007). Using a multivariate analysis approach and data from the National Survey of Charities and Social Enterprises (NSCSE), it is found that trading activities are used relatively commonly in deprived areas. These organisations are also more likely to attempt to access public sector funds. This suggests policy-makers need to consider the impact of funding cuts on TSOs in the most deprived areas as TSOs are unlikely achieve their objectives without continuing support
