A proposal for a study of motive processing
No full textThis was a contribution to the Cognition and Affect project that led to the Ph.D. thesis of the first author (Luc P. Beaudoin). This paper was mostly written by the first author, although it is based on and develops ideas of the second author. The nursemaid scenario was first described by the second author (Sloman, 1986). The first author was in the process of implementing the model described in the paper.Thanks to Aluizio Arujo, Peter Greenfield, Inman Harvey, Tim Read, Edmund Shing, Sharon Wood, and Shiu Yuen for reading and commenting on drafts.

A test of the somnolent mentation theory and the cognitive shuffle insomnia treatment
No full textInsomnia affects about 33% of Americans according to Harvey & Tang (2003) who called for new cognitive treatments.
We will report preliminary results from a test of (a) the Somnolent Mentation theory (SMT) of sleep onset (SO) and (b)
a new cognitive treatment for insomnia, the cognitive shuffle (CS), derived from the SMT (Beaudoin, 2013, 2014). According
to SMT, incoherent mentation characteristic of SO is not merely a side-effect of the SO period but promotes it, meaning it
is somnolent. The SMT identifies several types of insomnolent mentation, which involve sense making (e.g., problem solving).
SMT postulates counter-insomnolent mentation, thought patterns that interfere with insomnolent mentation. The CS is
predicted to be both somnolent and counter-insomnolent (super-somnolent). Participants either engage in constructive worry
Carney & Waters (2006) or in the CS using SomnoTest an iOS app developed by CogSci Apps Corp. (led by Beaudoin) based
on mySleepButton

No full textThis catalogue accompanies an exhibition by three artists whose practices question abstract painting. In his formal and pictorial analysis of the works, author Lussier underlines how the term “abstract paintings” (in the plural) is more appropriate for describing the genre today. Beaudoin adopts the viewer’s perspective and claims that painting remains relevant and innovative despite the rise of new media practices. Texts in French and English.

Tagging of Biomedical Articles on CiteULike: A Comparison of User, Author and Professional Indexing
No full textThis paper examines the context of online indexing from the viewpoint of three different groups: users, authors, and professional indexers. User tags, author keywords and descriptors were collected from academic journal articles, which were both indexed in Pubmed and tagged on CiteULike, and analysed. Descriptive statistics, informetric measures, and thesaural term comparison shows that there are important differences in the use of keywords between the three groups in addition to similarities which can be used to enhance support for search and browse. While tags and author keywords were found that matched descriptors exactly, other terms which did not match but provided important expansion to the indexing lexicon were found. These additional terms could be used to enhance support for searching and browsing in article databases as well as to provide invaluable data for entry vocabulary and emergent terminology for regular updates to indexing systems. Additionally, the study suggests that tags support organisation by association to task, projects and subject while making important connections to traditional systems which classify into subject categories
CASTING Contradictive LANDSCAPES: a thesis by sarah catherine beaudoin
No full textThis thesis aims to bring functionally obsolescent architectural elements to the forefront of design analysis, in the pursuit of architectural character over typology. The analysis is not of buildings, but rather how their recognizable ordinary elements can adopt alternate personalities, identities, and attitudes to the landscapes in which they inhabit.
Here, the understanding of what it means to be “ordinary” is critical. The ordinary is always leftover, comedown, fallen. In this, it is seen that we do not remember ordinary typologies, but rather the everyday features and characters that make up their compositions. This thesis seeks to draw on this idea of legibility through the use of projective character.
In this Thesis Prep analysis the author argues for characters with the contradictory qualities, claiming obsolescence is merely a call for the employment of character mis-calibrations.With this in mind, the research focuses on the chimney: a globally recognized architectural element on the verge of functional obsolescence. Here the research aims to propose a fictional landscape composed of projective characters, arguing that the formal and didactic qualities of the architectural chimney promote new and contradictory narratives, with the power to assert their familiar image across novel visual landscapes. Thus, the overarching goal of this thesis is to create a new conversation in what it means to preserve or reframe a visual architectural landscape of obsolescence

COLOUR. Yellow or reddish brown metasternum, antennal club in part darker; often prothorax and elytra with dark stripes or oblique bands; in male, elytra with long erect setae on margins and on suture but not on base of interstria 4. HEAD. Strongly punctate, punctuation partly confluent towards frontal fovea; forehead in male with prominent carinae against eyes and depressed between them, in female with low or obsolescent carina and not depressed; rostrum in male as long as prothorax, in female 1.2–1.4 × longer, cylindrical, 5-carinate in basal ¾, median carina widening near antennal insertion, apical ¼ smooth and punctate, underside in male lacking erect hairs and postmental tubercle; antennae yellowish or reddish brown, insertion on rostrum median in male, antemedian in female; scape slightly curved, gradually thickening toward apex, first segment of funicle elongate, in male as long as segments 2–4, in females longer than segments 2–4, segment 2 longer than wide, 3 isodiametric, 4–7 transverse, gradually widening to width of club. PROTHORAX. Sub-trapezoidal (w/l ratio: 1.46), converging in a straight or nearly straight line, deeply bisinuous at base, concavely curved at apex; apical collar at base with a transverse row of black dots; disc in lateral view nearly flat, with four impressions anteriorly, and a pair of large, deep foveae on either side of middle; integument with double punctuation, glabrous in appearance, with a very short pubescence mainly on sides at basal half; carina in lateral view obsolete or obsolescent towards base, weakly sinuous near apex, sharply carinate on collar. ELYTRA. Widest near middle (w/l ratio: 0.70), in male not tectiform, base of interstriae 3–5 raised to a tumour or swelling, apical ¾ of suture darker, slightly raised with a row of erect setae, interstria 10 in male swollen, somewhat inflated bearing long upwardly curved erect setae, interstria 9 in female costate in basal ¾; striae as wide as width of interstriae or slightly narrower, gradually fading apicad; stria 9 absent basally, starting from near height of fore coxae; dark stripe on elytra generally present on interstria 6 in basal half and between middle of interstriae 3 or 4 to 8 before declivity. LEGS. Integument pale yellow, mostly glabrous, with whitish suberect hairs in apical ¾ of tibiae and on tarsus; tibiae bisinuate on ventral side, with a small mucro apically; tarsi with first segment elongate, 0.7 as long as segments 2+3; segment 3 deeply bilobate; segment 4 elongate, slightly shorter than 1+2+3; claws free, not apendiculate. ABDOMEN. Tergite 7 with about 14 plectral granules; ventrites with short suberect, scattered whitish hairs; in male ventrites 1 and 2 impressed in middle, without specific pilosity on margin on impression. GENITALIA. Penis as long as last three ventrites; body 1.7 × longer than apodemes, symmetrical, more than 2 × longer than wide (w/l ratio: 0.40), parallel-sided, blunt at apex (Fig. 4E), with a pair of small median sclerites. Life history All the specimens collected recently were found on inflorescences of the oil palm, Elaeis guineensis (Arecaceae) (JH pers. obs.). Distribution Benin (Cotonou); Cameroon (Bota); Ghana (Aburi); Nigeria (Ife); Senegal (Malika-Dakar). Remarks Elaeidobius pilimargo sp. nov. is characterised by its elytral margins bearing long erect setae and presence of a swelling on base of interstria 4 without erect setae in males (Fig. 5 J–K). The likely females examined are not part of the type series because their identity cannot be guaranteed based on morphology. Elaeidobius pilimargo sp. nov. is morphologically close to E. singularis. Both species show a genetic distance of 2.01% on COII (JHAR00409_0201, Senegal / JHAR00283_0101, Ghana). The sequencing of the COI gene for specimens of E. singularis failed repetitively, probably due to polymorphism in the primer sequences. Within the E. plagiatus species group, the COI sequence of E. pilimargo sp. nov. showed a genetic distance of 2.88% with E. piliventris sp. nov. (JHAR02182_0101).Published as part of Haran, Julien M., Beaudoin-Ollivier, Laurence, Benoit, Laure & Kuschel, Guillermo, 2020, Revision of the palm-pollinating weevil genus Elaeidobius Kuschel, 1952 (Curculionidae, Curculioninae, Derelomini) with descriptions of two new species, pp. 1-32 in European Journal of Taxonomy 684 on pages 14-17, DOI: 10.5852/ejt.2020.684, http://zenodo.org/record/395911
La réforme des institutions centrales. Quelques jalons
No full text« In this article the author envisages and studies the reform of the Senate, of the House of Commons and of the Supreme Court of Canada ; the function of the Governor General is also considered. A suggestion is made for introducing a system of mitigated proportional representation in the House of Commons, as proposed by the Pepin-Robarts report of January 1979. The authors analyses the advantages and disadvantages of an elected Senate, of a Senate whose members are appointed by the federal government or by the federal and provincial governments, of a second House which would constitute a House of the Provinces ; the author is aganist an equal representation of the provinces in the Senate. Professor Beaudoin favours a specialized constitutional Court of Canada, although he considers that such a reform is very unlikely to happen ; however, he adds that in any case, the Supreme Court is de facto a constitutional court to a certain extent. He recommends that the principle of dualism be more visible. Finally, the author describes how the function of Governor General has evolved since 1926, and outlines the role that the Governor General may play in normal and anormal times.
