University press publishing consortium for Africa : lessons from academic libraries

This paper presents the results of a case study of the policies and practices of six African university presses. Based on the findings, it posits the formation of a consortium of African university presses. It borrows heavily from consortium formation in the library world

Teorias sobre fasores dinâmicos obtidas a partir de transformadas integrais

The Classical Phasor Theory goes back to the pioneer work of Charles Proteus Steinmetz in the study of alternating current electrical circuits. According to Steinmetz, a classical or static phasor is a complex number that represents a sinusoidal function whose amplitude, phase and angular frequency are constants and it transforms ordinary differential equations with constant coefficients, which are models for alternating current electrical circuits, in linear systems with complex coefficients. When either amplitude, phase or angular frequency is no longer constant, the phasor theory must be adapted in such a way to preserve the classical results. In this new theory, which deals with a large class of functions rather than only sinusoidal functions, the phasor is called dynamic or timevariable phasor. Following this line, the main objective of this work is to present three new theories about dynamic phasors built from integral transforms, namely, the short-term Fourier transform, the generalized Laplace transform and the Hilbert transform. More precisely, the dynamic phasors arise through injective linear operators between suitable vector spaces and they have similar properties to those of the dynamic phasors usually found in the literature.Agência 1A Teoria Fasorial Clássica remonta ao trabalho pioneiro de Charles Proteus Steinmetz no estudo de circuitos elétricos de corrente alternada. Segundo Steinmetz, um fasor clássico ou estático é um número complexo que representa uma função senoidal cuja amplitude, fase e frequência angular são constantes e transforma equações diferenciais ordinárias com coeficientes constantes, que por sua vez são modelos para circuitos elétricos de corrente alternada, em sistemas lineares com coeficientes complexos. Quando a amplitude, a fase ou a frequência angular não é mais constante, a teoria sobre os fasores deve ser adaptada de modo a preservar os resultados clássicos. Nesta nova teoria, que lida com uma grande classe de funções, e não apenas as funções senoidais, o fasor é denominado dinâmico ou fasor variável no tempo. Seguindo esta linha, o principal objetivo deste trabalho é apresentar três novas teorias sobre fasores dinâmicos construídas a partir de transformadas integrais, a saber, a transformada de Fourier de curto termo, a transformada generalizada de Laplace e a transformada de Hilbert. Mais precisamente, os fasores dinâmicos surgem através de operadores lineares injetores entre espaços vetoriais adequados e têm propriedades semelhantes às dos fasores dinâmicos usualmente encontrados na literatura

Phénoménologie et psychanalyse, une problématique "parenté"?

International audienceIl s'agira de faire état, en amont de la question d’un dialogue possible, de ce qui a été jusqu’à maintenant peu évoqué dans les divers articles de cet ouvrage, à savoir de ce qui sépare ces deux champs théoriques : la phénoménologie et la psychanalyse. Non pas dans le but de réfuter la possibilité de tout dialogue entre ces deux discours (l’altérité n’a jamais rendu impossible le dialogue puisque celui-ci naît d’un écart). Mais dans le but de mettre en question la « parenté » de l’une avec l’autre. C’est en effet par ce terme que Merleau-Ponty désignait le rapport de la phénoménologie et de la psychanalyse, souhaitant même, disait-il, « aggraver » cette parenté. Dans sa Préface à Hesnard de 1961 , il affirme à cet égard qu’elles « se dirigent toutes deux vers la même latence », soutenant par là que la quête de l’une et de l’autre à défaut d’adopter une méthode semblable comportent un même horizon. On ne s’étonne pas assez de ce rapprochement qu’opère Merleau-Ponty entre ce que la phénoménologie a nommé le pré-réflexif et la psychanalyse l’inconscient. Aussi s’agira-t-il premièrement de faire entendre l’originalité d’une telle affirmation dans le contexte phénoménologico-psychanalytique. Puis d’ouvrir des pistes pour envisager les difficultés qui demeurent à supposer une telle parenté si l’on souhaite conserver son tranchant à l’invention freudienne

“A World Not Dependent on Sales: Sustainable, OA Monograph Publishing”--P2L3 Summary and Next Steps: P2L3 Meeting June 14, 2019, Detroit, MI

Table of Contents P2L3 Meeting Planning Committee 3 Land Acknowledgment 3 Participants 3 Introduction 5 Presentations 7 Opening Plenary: Generous Thinking Lightning Rounds Promising New Models: MIT and University of Michigan MIT University of Michigan Highlights from Roundtable Discussions 11 Digital Scholarship and Digital Humanities Flipping the Financial Model for Monographs Engaging with Library Communications and Development Next Steps for P2L 13 Endnotes 14 In choosing as its theme a “world not dependent on sales,” the P2L3 Meeting Planning Committee situated P2L in the context of a long-running Andrew W. Mellon Foundation–funded research and innovation agenda on monographs in the digital age.1 Most recently, Ithaka S+R in 2019 laid out the trend lines for university press publishing and library expenditure, which found that while library spending for university press titles is relatively steady, e-book purchases are increasing and print book purchases are decreasing. With e-books nearly twice the cost of print, on average, this steady state amounts to a decline in titles purchased. The report concluded: As predicted by others in the industry, only a fifth of library book expenditures are for university press titles. The academic library really is not the university press’s sole or even top customer, but the nearly 20 percent fall in spending for university press titles over the four-year period [2014–2017] doesn’t bode well for the health of these presses, especially if they continue to rely on onetime print book sales as their main source of revenue.2 P2L is one of two active partnerships between the Association of Research Libraries (ARL) and the Association of University Presses (AUPresses). The other is Toward an Open Monograph Ecosystem (TOME), a joint pilot initiative of ARL, AUPresses, and the Association of American Universities. TOME is one of several active experiments aiming to flip the financial model of the press whereby the institution pays upfront for the cost of publication, rather than relying on its sales. In preparing for a post-sales-dependent environment, the planning committee considered the unique strength of the P2L community with its organizational and operational alignment between the library and the press

Open access in Australia: an odyssey of sorts?

Scholarly communication change and open access (OA) initiatives in Australia have followed an Odyssean path in the last decade. The stop-start nature of early initiatives demonstrates that institutional leadership is essential for the successful deposit of academic content in an institutional repository. Similarly, OA policies from the two Australian Research Councils were delayed for nearly a decade, partly due to publisher pressure and bureaucratic conservatism. More successful has been the development of full, or hybrid, open access university e-presses. These presses, usually embedded in the scholarly infrastructure of the university, provide monographic models for wider global consideration. Australian universities are now reflecting, partly through recent Research Council edicts and monitoring global OA developments, greater awareness of the need for action in scholarly communication change Journal: Insights 26.3 (2013): 282-28

The critical events for motor-sensory temporal recalibration

Determining if we, or another agent, were responsible for a sensory event can require an accurate sense of timing. Our sense of appropriate timing relationships must, however, be malleable as there is a variable delay between the physical timing of an event and when sensory signals concerning that event are encoded in the brain. One dramatic demonstration of such malleability involves having people repeatedly press a button thereby causing a beep. If a delay is inserted between button presses and beeps, when it is subsequently taken away beeps can seem to precede the button presses that caused them. For this to occur it is important that people feel they were responsible for instigating the beeps. In terms of their timing, as yet it is not clear what combination of events is important for motor-sensory temporal recalibration. Here, by introducing ballistic reaches of short or longer extent before a button press, we varied the delay between the intention to act and the sensory consequence of that action. This manipulation failed to modulate recalibration magnitude. By contrast, introducing a similarly lengthened delay between button presses and consequent beeps eliminated recalibration. Thus it would seem that the critical timing relationship for motor-sensory temporal recalibration is between tactile signals relating to the completion of an action and the subsequent auditory percept

Eye gaze position before, during and after percept switching of bistable visual stimului

A bistable visual stimulus, such as the Necker Cube or Rubin’s Vase, can be perceived in two different ways which compete against each other and alternate spontaneously. Percept switch rates have been recorded in past psychophysical experiments, but few experiments have measured percept switches while tracking eye movements in human participants. In our study, we use the Eyelink II system to track eye gaze position during spontaneous percept switches of a bistable, structure-from-motion (SFM) cylinder that can be perceived to be rotating clockwise (CW) or counterclockwise (CCW). Participants reported the perceived direction of rotation of the SFM cylinder using key presses. Reliability of participants’ reports was ensured by including unambiguous rotations. Unambiguous rotation was generated by assigning depth using binocular disparity. Gaze positions were measured 50 – 2000 ms before and after key presses. Our pilot data show that during ambiguous cylinder presentation, gaze positions for CW reports clustered to the left half of the cylinder and gaze positions for CCW reports clustered to the right half of the cylinder between 1000ms before and 1500ms after key presses, but no such correlation was found beyond that timeframe. These results suggest that percept switches can be correlated with prior gaze positions for ambiguous stimuli. Our results further suggest that the mechanism underlying percept initiation may be influenced by the visual hemifield where the ambiguous stimulus is located.Published versio
