Uniformization of affine dependence programs for parallel embedded system design

This paper is concerned with the uniformization of a system of afine recurrence equations. This transformation is used in the design (or compilation) of highly parallel embedded systems (VLSI systolic arrays, signal processing filters, etc.). In this paper, we present and implement an automatic system to achieve uniformization of systems of afine recurrence equations. We unify the results from many earlier papers, develop some theoretical extensions, and then propose effective uniformization algorithms. Our results can be used in any high level synthesis tool based on polyhedral representation of nested loop computations.

Making the least active pay: a simulation of rewards and penalties under Demand Side Participation programs

The orthodox approach for incentivising Demand Side Participation (DSP) programs is that utility losses from capital, installation and planning costs should be recovered under financial incentive mechanisms which aim to ensure that utilities have the right incentives to implement DSP activities. The recent national smart metering roll-out in the UK implies that this approach needs to be reassessed since utilities will recover the capital costs associated with DSP technology through bills. This paper introduces a reward and penalty mechanism focusing on residential users. DSP planning costs are recovered through payments from those consumers who do not react to peak signals. Those consumers who do react are rewarded by paying lower bills. Because real-time incentives to residential consumers tend to fail due to the negligible amounts associated with net gains (and losses) or individual users, in the proposed mechanism the regulator determines benchmarks which are matched against responses to signals and caps the level of rewards/penalties to avoid market distortions. The paper presents an overview of existing financial incentive mechanisms for DSP; introduces the reward/penalty mechanism aimed at fostering DSP under the hypothesis of smart metering roll-out; considers the costs faced by utilities for DSP programs; assesses linear rate effects and value changes; introduces compensatory weights for those consumers who have physical or financial impediments; and shows findings based on simulation runs on three discrete levels of elasticity.

Venues on the verges: London's theater government between 1594 and 1614

In 1594, major decisions were made by the governors of London and the country about plays and playing. We need to learn what lay behind these events, such as what led James Burbage to build his Blackfriars theater in 1596. That initial fiasco might tell us much about what lay behind Shakespeare’s decision to join the new Chamberlain’s Men in 1594 and his subsequent commitment to them as a full-time playwright. When the Globe burned down in 1613, a majority of the shareholders decided to rebuild it at great cost, but Shakespeare withdrew. The rebuilding was old-fashioned thinking, reverting to the company’s desire, asserted in 1594, to play indoors in winter, which helps to clarify their decisions and Shakespeare’s own—to write plays rather than more long poems. The few surviving papers of the Privy Council and the London mayoralty from the time suggest that one of the two new companies of 1594 preferred to play indoors during the winter instead of at their allocated open playhouses in the suburbs. They tried to renew this traditional practice, first in 1594 and again in 1596 when James Burbage built the indoor Blackfriars playhouse for them. The renewal of the Globe in 1614 was part of the same thinking, although Shakespeare evidently opted out of the decision.

Do IMF and World Bank programs induce government crises? an empirical analysis

We examine whether and under what circumstances World Bank and International Monetary Fund (IMF) programs affect the likelihood of major government crises. We find that crises are, on average, more likely as a consequence of World Bank programs. We also find that governments face an increasing risk of entering a crisis when they remain under an IMF or World Bank arrangement once the economy's performance improves. The international financial institution's (IFI) scapegoat function thus seems to lose its value when the need for financial support is less urgent. While the probability of a crisis increases when a government turns to the IFIs, programs inherited by preceding governments do not affect the probability of a crisis. This is in line with two interpretations. First, the conclusion of IFI programs can signal the government's incompetence, and second, governments that inherit programs might be less likely to implement program conditions agreed to by their predecessors.

Globalisation and MA TESOL programs in the UK

This article reports the results of a mixed-methods approach to investigating the association between globalisation and MATESOL in UK universities. Qualitative and quantitative data collected from academic staff through eight emails, four interviews and 41 questionnaires indicate that the globalised context of higher education have affected these programmes in a number of ways including an increasing interest in recruiting more international students and a growing awareness about the need for curriculum and content modifications. The analysis of the data suggests that although change has been an inherent characteristic of these MAs over the past decade, it has been implemented gradually and conservatively, often relying on a dialectic relationship between academic staff and universities’ policies. The results imply that factors other than globalisation have also been at work. Many of the participants contend that globalisation has not lowered the quality of these MAs or standards of good practice.

Samuel Beckett, the Gate Theatre Dublin, and the contemporary Irish independent theater sector: fragments of performance history

From 1991, when the Dublin Gate Theatre launched their Samuel Beckett Festival featuring nineteen of Beckett’s stage plays, to more recent years, the Gate dominated Irish productions of Beckett’s theater. The Gate Beckett Festival was remounted in 1996 at the Lincoln Center, New York, and at the Barbican Centre, London, in 1999, and individual or grouped productions have toured regularly since then in Ireland and internationally. However, since the Irish premiere of Waiting of Godot at the Pike Theatre in 1955, in addition to several Beckett plays mounted by the National Theatre, many independent Irish theater companies, such as Focus Theatre, Druid Theatre, and more recently Pan Pan Theatre, Blue Raincoat Theatre, The Corn Exchange, and Company SJ (under director Sarah Jane Scaife), have produced Beckett’s drama. While acknowledging earlier Irish productions, this essay will consider the role of the Dublin Gate Beckett Festival and the Beckett Centenary celebrations in Dublin in 2006 in greatly enhancing the marketability of Beckett’s work, and will discuss the proliferation of productions of Beckett’s stage plays (as opposed to stage adaptations of the prose work, which is a topic for another essay) in the independent theater sector in the Republic of Ireland since 2006. In addition to giving an overview of these recent productions, the essay will consider some issues at stake in creating or constructing performance histories

Precise analysis of array usage in scientific programs

The automatic transformation of sequential programs for efficient execution on parallel computers involves a number of analyses and restructurings of the input. Some of these analyses are based on computing array sections, a compact description of a range of array elements. Array sections describe the set of array elements that are either read or written by program statements. These sections can be compactly represented using shape descriptors such as regular sections, simple sections, or generalized convex regions. However, binary operations such as Union performed on these representations do not satisfy a straightforward closure property, e.g., if the operands to Union are convex, the result may be nonconvex. Approximations are resorted to in order to satisfy this closure property. These approximations introduce imprecision in the analyses and, furthermore, the imprecisions resulting from successive operations have a cumulative effect. Delayed merging is a technique suggested and used in some of the existing analyses to minimize the effects of approximation. However, this technique does not guarantee an exact solution in a general setting. This article presents a generalized technique to precisely compute Union which can overcome these imprecisions.

Queering Philip Roth: homosocial discourse in 'An actor’s life for me', 'Letting go', 'Sabbath’s theater' and the 'American trilogy'

Much has been written on Roth’s representation of masculinity, but this critical discourse has tended to be situated within a heteronormative frame of reference, perhaps because of Roth’s popular reputation as an aggressively heterosexual, libidinous, masculinist, in some versions sexist or even misogynist author. In this essay I argue that Roth’s representation of male sexuality is more complex, ambiguous, and ambivalent than has been generally recognized. Tracing a strong thread of what I call homosocial discourse running through Roth’s oeuvre, I suggest that the series of intimate relationships with other men that many of Roth’s protagonists form are conspicuously couched in this discourse and that a recognition of this ought to reconfigure our sense of the sexual politics of Roth’s career, demonstrating in particular that masculinity in his work is too fluid and dynamic to be accommodated by the conventional binaries of heterosexual and homosexual, feminized Jew and hyper-masculine Gentile, the “ordinary sexual man” and the transgressively desiring male subject.

Aligning IS programs with industry: linking business analysis curricula design with the professional body

Aligning information systems (IS) solutions with business goals and needs are crucial for IS activities. IS professionals who are able to work closely with both the business and technical staff are key enablers of business and IT alignment. IS programs in higher education (HE) institutions have a long tradition of enabling graduates to develop the appropriate skills needed for their future careers. Yet, organizations are still having difficulty finding graduates who possess both the knowledge and skills that are best suited to their specific requirements. Prior studies suggest that IS curricula are often ill-matched with industry/business needs. This study reports on the business analysis curricula (re) design which was undertaken to align it with a key professional body for the IS industry. This study presents the approaches taken in the (re) design of the module, and provides a discussion of the wider implications for IS curricula design. The results show a positive outcome for the HE and professional body partnership.
