Para uma história de uma ordem secreta de filiação monárquica : Sociedade Secreta de São Miguel da Ala (1848-1859)

De óbvias inspirações maçónico-Carbonárias, “mas com intenções absolutamente contrárias”, a Ordem de São Miguel da Ala era uma associação secreta, militante e política, sobretudo “revolucionária e anti-dinástica”, tendo D. Miguel de Bragança como força centrífuga/centrípeta. Em outras palavras, “a sociedade era Católica, Apostólica, Romana e Miguelista e, no entanto, absolutamente secreta,exigindo o juramento inviolável sobre pessoas e coisas”.

On the spectra and pseudospectra of a class of non-self-adjoint random matrices and operators

In this paper we develop and apply methods for the spectral analysis of non-selfadjoint tridiagonal infinite and finite random matrices, and for the spectral analysis of analogous deterministic matrices which are pseudo-ergodic in the sense of E. B. Davies (Commun. Math. Phys. 216 (2001), 687–704). As a major application to illustrate our methods we focus on the “hopping sign model” introduced by J. Feinberg and A. Zee (Phys. Rev. E 59 (1999), 6433–6443), in which the main objects of study are random tridiagonal matrices which have zeros on the main diagonal and random ±1’s as the other entries. We explore the relationship between spectral sets in the finite and infinite matrix cases, and between the semi-infinite and bi-infinite matrix cases, for example showing that the numerical range and p-norm ε - pseudospectra (ε > 0, p ∈ [1,∞] ) of the random finite matrices converge almost surely to their infinite matrix counterparts, and that the finite matrix spectra are contained in the infinite matrix spectrum Σ. We also propose a sequence of inclusion sets for Σ which we show is convergent to Σ, with the nth element of the sequence computable by calculating smallest singular values of (large numbers of) n×n matrices. We propose similar convergent approximations for the 2-norm ε -pseudospectra of the infinite random matrices, these approximations sandwiching the infinite matrix pseudospectra from above and below.

The three faces of bounded reliability: Alfred Chandler and the micro-foundations of management theory

Alfred Chandler, the celebrated business historian, provided detailed descriptions of the reasons for failed human commitments and the managerial tools needed to prevent/remediate such failings in the context of large business firms. Chandler's historical narrative identifies three distinct “faces” of bounded reliability—opportunism, benevolent preference reversal, and identity-based discordance—as the main drivers of commitment failure. Adopting bounded reliability (BRel) as a micro-foundation in management studies will raise the quality and relevance of scholarly recommendations to improve managerial decision making and action, because analysis of BRel challenges closely mirrors the real-world problems facing practicing managers.

Inspired by the past, driven by the passion: music in state-supported education in New South Wales and Victoria 1848-1920

This investigation considers the development of class music teaching in New South Wales and Victoria during the first seventy-two years of state-supported primary education. The first chapter describes the English background including music teaching methods (resulting from the mid-nineteenth century English choral singing movement) and the subsequent development of music teaching in English elementary schools. The promotion of school music is then considered on a broadly chronological basis in the two states and several themes are identified in relation to school music policy and practice. These include the status of music (core curriculum or extra-curricular subject), who should teach music (generalist or specialist teachers), what teaching methods and music notation should be used (staff or Tonic Sol-fa), musical training for generalist teachers, and curriculum content in relation to the aims and objectives of school music. Comparisons are made between developments in both states and between both states and English school music. The final chapter demonstrates the relevance of many of the historical themes identified for music education today. The thesis concludes by identifying a recurring problem from the past. namely the lack of co-ordination between various aspects of school music policy, as the most serious problem to be overcome in the future.
