Commentary 1 on Reflections on Theories of Learning by Paul Ernest

2009

Paul Ernest is an internationally recognised authority on the philosophy of social-constructivism particularly in the context of mathematics education. He has published widely on the issue, perhaps his two best known and widely cited works are ‘The Philosophy of Mathematics Education’ (Ernest 1991), and ‘Social Constructivism as a Philosophy of Mathematics’ (Ernest 1998). As one engages with this short paper it is evident that one is in the company of a ‘master’ of the topic. It is quite remarkable how within the space of about 4000 words he manages to produce an erudite and informative account of 4 related theories of learning, and outline some of their implications for teaching.

Interpersonal Recognition and Responsiveness to Relevant Differences

2006

Abstract This essay defends a three‐dimensional response‐model theory of recognition of persons, and discusses the related phenomenon of recognition of reasons, values and principles. The theory is three‐dimensional in endorsing recognition of the equality of persons and two kinds of relevant differences: merits and special relationships. It defends a ‘response‐model’ which holds that adequacy of recognition of persons is a matter of adequate responsiveness to situation‐specific reasons and requirements. This three‐dimensional response‐model is compared to Peter Jones’s view, which draws the distinction between status and merit recognition, and mediated and unmediated recognition. The essay…

Charge reconstruction in large-area photomultipliers

2018

Large-area PhotoMultiplier Tubes (PMT) allow to efficiently instrument Liquid Scintillator (LS) neutrino detectors, where large target masses are pivotal to compensate for neutrinos' extremely elusive nature. Depending on the detector light yield, several scintillation photons stemming from the same neutrino interaction are likely to hit a single PMT in a few tens/hundreds of nanoseconds, resulting in several photoelectrons (PEs) to pile-up at the PMT anode. In such scenario, the signal generated by each PE is entangled to the others, and an accurate PMT charge reconstruction becomes challenging. This manuscript describes an experimental method able to address the PMT charge reconstruction …

Time imaging reconstruction for the PANDA Barrel DIRC

2020

The innovative Barrel DIRC (Detection of Internally Reflected Cherenkov light) counter will provide hadronic particle identification (PID) in the central region of the PANDA experiment at the new Facility for Antiproton and Ion Research (FAIR), Darmstadt, Germany. This detector is designed to separate charged pions and kaons with at least 3 standard deviations for momenta up to 3.5 GeV/c, covering the polar angle range of 22$^{\circ}$-140$^{\circ}$. An array of microchannel plate photomultiplier tubes is used to detect the location and arrival time of the Cherenkov photons with a position resolution of 2 mm and time precision of about 100 ps. The time imaging reconstruction has been develop…

Inclusion of Inter Crystal Scatter data in PET

2012

In PET, as the spatial resolution of the measurement system is increased, multiple interactions of a single photon may be separately measured and such events are often removed from the data used in image reconstruction. While for some PET imaging tasks this effect is unimportant, for primate, brain and high-spatial-resolution imaging where sensitivity is important, such Inter Crystal Scattering (ICS) events may constitute a large fraction of the measured data. On-the-fly list-mode image reconstruction is generally required in order to use all the information provided by ICS. Simulated One-Pass List-mode image reconstruction is used in this investigation to study the inclusion of ICS informa…

Sensitivity recovery for the AX-PET prototype using inter-crystal scattering events

2014

The development of novel detection devices and systems such as the AX-positron emission tomography (PET) demonstrator often introduce or increase the measurement of atypical coincidence events such as inter-crystal scattering (ICS). In more standard systems, ICS events often go undetected and the small measured fraction may be ignored. As the measured quantity of such events in the data increases, so too does the importance of considering them during image reconstruction. Generally, treatment of ICS events will attempt to determine which of the possible candidate lines of response (LoRs) correctly determine the annihilation photon trajectory. However, methods of assessment often have low su…

Domain-specific intensifying constructions and/in weather-related proverbs. A case study based on Dutch dialects in Flanders.

2021

International audience; [Introduction] There are few things so rigorously present in human consciousness and communication as the subject of the weather. Nevertheless, both in formal (weather forecasts) and informal contexts (daily conversations), this “weather discourse” remains understudied within linguistics (Liégeois 2019). This kind of discourse (Koch & Oesterreicher 1985), however, appears very interesting to different constructionist approaches (Gautier 2018), such as frame semantics and (cognitive) construction grammar. [Research question] In this context, this proposal looks from a constructionist perspective into what could be called “weather sayings” in the dialects of Flanders; …

Le continuum lexique-grammaire en genre spécialisé à partir de corpus maison

2017

International audience; [Problématique et objectifs] La proposition, qui s’inscrit dans l’axe 5 de l’appel « Corpus, études contrastives et traduction » vise à interroger l’apport des corpus spécialisés maison (Loock 2016a, b) pour la mise au jour, pour la traduction professionnelle et la formation de traducteurs, des patrons lexico-grammaticaux inhérents à des moules textuels (Gautier 2009) hautement contraints, en langue(s) traduite(s). On discutera en particulier, à la suite de Kübler/Gledhill (2016 : 75), l’idée selon laquelle l’interrogation systématique de corpus homogènes permet d’aboutir à une représentation holistique vérifiée des interactions entre lexique et grammaire, surtout qu…
