AbstractWe give a survey on the Stokes structure of a good meromorphic flat bundle. We also show that a meromorphic flat bundle has the good formal structure if and only if it has a good lattice.

The epitaxial growth of III-V semiconductors on Si for integrated optoelectronic applications is currently of great interest. GaP, with a lattice constant close to that of Si, is an attractive buffer between Si and, for example, GaAsP. In spite of the good lattice match, the growth of device quality GaP on Si is not without difficulty. The formation of antiphase domains, the difficulty in cleaning the Si substrates prior to growth, and the poor layer morphology are some of the problems encountered. In this work, the structural perfection of GaP layers was investigated as a function of several process variables including growth rate and temperature, and Si substrate orientation. The GaP layers were grown in an atmospheric pressure metal organic chemical vapour deposition (MOCVD) system using trimethylgallium and phosphine in H2. The Si substrates orientations used were (100), 2° off (100) towards (110), (111) and (211).

Walter Pater's late-nineteenth-century literary genre of the imaginary portrait has received relatively little critical attention. Conceived of as something of a continuum between his role as an art critic and his fictional pursuits, this essay probes the liminal space of the imaginary portraits, focusing on the role of the parergon, or frame, in his portraits. Guided by Pater's reading of Kant, who distinguishes between the work (ergon) and that which lies outside of the work (the parergon), between inside and outside, and contextualised alongside the analysis of Derrida, who shows how such distinctions have always already deconstructed themselves, I demonstrate a similar operation at work in the portraits. By closely analysing the parerga of two of Pater's portraits, ‘Duke Carl of Rosenmold’ (1887) and ‘Apollo in Picardy’ (1893), focusing on his partial quotation of Goethe in the former, and his playful autocitation and impersonation of Heine in the latter, I argue that Pater's parerga seek to destabilise the relationship between text and context so that the parerga do not lie outside the text but are implicated throughout in their reading, changing the portraits constitutively. As such, the formal structure of the parergon in Pater's portraits is also a theoretical fulcrum in his aesthetic criticism and marks that space where the limits of, and distinctions between, art and life become blurred.

The economic crisis showed the weaknesses of the institutional system of the European Union, raising questions about its shape. The article aims to determine whether internal structures of the EU institutions and their modes of operation are chances or barriers for effective treaty implementation and the ability of institutions to face unexpected, difficult situations. The article focuses both on the formal structure of the institutions and their human resources. The article aims to conclude if the crisis may give impetus to a significant improvement in the EU institutional system.

Abstract Application of a formal Failure Analysis metaprocess to a stubborn yield loss problem provided a framework that ultimately facilitated a solution. Absence of results from conventional failure analysis techniques such as PEM (Photon Emission Microscopy) and liquid crystal microthermography frustrated early attempts to analyze this low-level supply leakage failure mode. Subsequently, a reorganized analysis team attacked the problem using a specific toplevel metaprocess.(1,a) Using the metaprocess, analysts generated a specific unique step-by-step analysis process in real time. Along the way, this approach encouraged the creative identification of secondary failure effects that provided repeated breakthroughs in the analysis flow. Analysis proceeded steadily toward the failure cause in spite of its character as a three-way interaction among factors in the IC design, mask generation, and wafer manufacturing processes. The metaprocess also provided the formal structure that, at the conclusion of the analysis, permitted a one-sheet summary of the failure's cause-effect relationships and the analysis flow leading to discovery of the anomaly. As with every application of this metaprocess, the resulting analysis flow simply represented an effective version of good failure analysis. The formal and flexible codification of the analysis decision-making process, however, provided several specific benefits, not least of which was the ability to proceed with high confidence that the problem could and would be solved. This paper describes the application of the metaprocess, and also the key measurements and causeeffect relationships in the analysis.

Most arguments of Applied Ethics (e.g.slippery slope argument, argument of double effect) are well analyzed. An exception is the argument 'I do not do this because it is not my duty'. It makes sense to call the argument the 'argument of supererogation' (ASE): Since J. Urmson's essay Saints and Heroes of 1958, those actions are called 'supererogations' which (despite of their moral value) are not supposed to be duties. The argument is widely used not only in Applied Ethics, but also in ordinary moral everyday life. Nevertheless, there is a need of investigation because it has an indecency-problem. The argument is convincing if an actor does not want to risk his life. It seems indecent, however, if an actor refuses a simple favor or a service of friendship with the 'argument of super-erogation', although they both constitute no duties. This paper reconstructs the 'argument of supererogation' as a syllogism. It analyzes its formal structure by benefitting from current Anglo-American literature on supererogation. The overall aim of this paper is to solve the problem of indecency.

Michael Heinrich, one of the leading Marx scholars, provides a general introduction into Das Kapital with emphasis on the latest interpretations of it. The circumstances surrounding its writing and publication are shown to have interfered with an adequate appreciation of it. The formal structure and organization of the first volume are obstacles to readers and demand much from their education and intellect. The article summarizes the basic trajectories of Marx’s criticisms of political economy, including the critique of naturalizing social forms arising under capitalism and Marx’s original monetary theory of value. The author disentangles Marx’s Das Kapital from views mistakenly ascribed to it, such as the idea that value is determined solely by labor and the prediction of pauperization of the masses. First, Marx’s theory of value goes well beyond explaining prices under capitalism. Second, his main prophecy concerned the inevitable growth of inequality between the masters of capital and the employed classes and did not forecast impoverishment. The paper also points out that the sequence of publication of different volumes of Das Kapital caused lacunae in interpreting Marx’s oeuvre. For instance Engels’ efforts made the third volume more accessible to readers but also obscured the overall pattern of Marx’s thinking. the article shows that Das Kapital was a dynamic and fluctuating project to such an extent that Marx himself several times revisited his views of the causes of economic crises and falling profits and also intended to deal extensively with ecological issues. Reaching an adequate understanding of the theory contained in Das Kapital cannot depend on the manuscripts of those volumes alone. Marx’s notebooks, which have only recently published, are an indispensable aid to understanding it.

This chapter examines the law governing the availability of claims to traceable proceeds. It argues that the language used in the case law—which uses the terminology of property rights and of fiduciary relationships—cannot fully explain the law, since such claims are often available in the absence of fiduciary duties and are not available to holders of many types of property right. It argues that such claims instead presuppose a relationship of ‘control of assets’: where the defendant has a legal power to deal with some asset, correlating to a vulnerability to a loss of rights in that asset on the part of the claimant, and coupled with a duty not to exercise the power. It argues that relationships that have this formal structure also share normative characteristics that justify the subordination of defendant autonomy that has been shown to be at the heart of the tracing concept.

The concepts of random error and reliability of measurements that are familiar in traditional theories based on the notions of “true values” and “errors” can be represented by a probability model having a simpler formal structure and fewer special assumptions about random sampling and independence of measurements. In this model formulas that relate observable events are derived from probability axioms and from primitive terms that refer to observable events, without an intermediate structure containing variances and correlations of “true” and “error” components of scores. While more economical in language and formalism, the model at the same time is more general than classical theories and applies to stochastic processes in which joint distributions of many dependent random variables are of interest. In addition, it clarifies some long-standing problems concerning “experimental independence” of measurements and the relation of sampling of individuals to sampling of measurements.

AbstractHow are listeners able to follow and enjoy complex pieces of music? Several theoretical frameworks suggest links between the process of listening and the formal structure of music, involving a division of the musical surface into structural units at multiple hierarchical levels. Whether boundaries between structural units are perceivable to listeners unfamiliar with the style, and are identified congruently between naïve listeners and experts, remains unclear. Here, we focused on the case of Indian music, and asked 65 Western listeners (of mixed levels of musical training; most unfamiliar with Indian music) to intuitively segment into phrases a recording of sitar ālāp of two different rāga-modes. Each recording was also segmented by two experts, who identified boundary regions at section and phrase levels. Participant- and region-wise scores were computed on the basis of "clicks" inside or outside boundary regions (hits/false alarms), inserted earlier or later within those regions (high/low "promptness"). We found substantial agreement—expressed as hit rates and click densities—among participants, and between participants' and experts' segmentations. The agreement and promptness scores differed between participants, levels, and recordings. We found no effect of musical training, but detected real-time awareness of grouping completion and boundary hierarchy. The findings may potentially be explained by underlying general bottom-up processes, implicit learning of structural relationships, cross-cultural musical similarities, or universal cognitive capacities.
