Bone loss around narrow implants versus standard diameter implants: Retrospective 2-years case-control study
2019
Background The objectives were to evaluate the bone loss (BL) around narrow diameter implants (3.3 mm) 2 years after implant loading and compare with the bone loss around conventional-diameter implants (4.1 mm), as well as with clinical and anatomical variables. 2-years follow-up. Material and Methods Cases: 20 patients either gender-age, narrow implants (Straumann TM-SLA, diameter 3.3 mm); Control: 20 patients matching for gender-age, conventional implants (Straumann TM-SLA, diameter 4.1). Total 82 implants (31 narrow implants and 51 conventional implants) in 40 patients. To avoid statistical bias, a cluster of one implant per patient was randomly selected (20 narrow implants and 20 conven…
An Interactive Framework for Offline Data-Driven Multiobjective Optimization
2020
We propose a framework for solving offline data-driven multiobjective optimization problems in an interactive manner. No new data becomes available when solving offline problems. We fit surrogate models to the data to enable optimization, which introduces uncertainty. The framework incorporates preference information from a decision maker in two aspects to direct the solution process. Firstly, the decision maker can guide the optimization by providing preferences for objectives. Secondly, the framework features a novel technique for the decision maker to also express preferences related to maximum acceptable uncertainty in the solutions as preferred ranges of uncertainty. In this way, the d…
The Semiotics of Test Design: Conceptual Framework on Optimal Item Features in Educational Assessment Across Cultural Groups, Countries, and Languages
2021
This paper offers a conceptual framework on test design from the perspective of social semiotics. Items are defined as arrangements of features intended to represent information, convey meaning, and capture information on the examinees’ knowledge or skills on a given content. The conceptual framework offers a typology of semiotic resources used to create items and discusses item representational complexity—the multiple ways in which the semiotic resources of an item are related to each other—and item semiotic alignment—the extent to which examinees share cultural experience encoded by items. Since the ability to make sense of items is shaped by the examinees’ level of familiarity with the s…
Cognitive Overload and Orthographic Errors: When Cognitive Overload Enhances Subject–Verb Agreement Errors. A Study in French Written Language
1994
Three experiments were carried out to test the hypothesis that cognitive overload enhances the occurrence of subject-verb agreement errors in French. Highly educated adults were presented orally with sentences they were required to write down. The sentences were of the types “N1 de N2 V” (Noun 1 of Noun 2 Verb: Le chien des voisins arrive/The neighbours’ dog is arriving) versus “Prl Pr2 V” (Pronoun 1 Pronoun 2 Verb: Il les aime/He likes them). In these sentences, N1 (Pr1) and N2 (Pr2) matched or mismatched in number. In the three experiments, the sentences had to be recalled either in an isolated condition (i.e. every presented sentence had to be immediately recalled) or with a concurrent …
Prevalence and determinants of secondary posttraumatic growth following trauma work among medical personnel: a cross sectional study.
2021
ABSTRACT Background: People helping trauma victims as a part of their work may experience positive results, known as Secondary Posttraumatic Growth (SPTG). Aim: The present study aimed to determine the prevalence and determinants of SPTG among medical personnel, considering occupational load, job satisfaction, social support, and cognitive processing of trauma, understood as cognitive coping strategies. Methods: Subjects comprised 419 representatives of the medical profession, including paramedics and nurses. The age of the subjects varied from 19 to 65 (M = 39.60; SD = 11.03). Four standard measurement tools were utilized: the Secondary Posttraumatic Growth Inventory, the Job Satisfaction …
Money, morality and magistrates: prosecuting and judging in the Republic of Benin

Since 2012, Beninese magistrates have gone on multiple strikes. Most of them complain about their substantial workload, low pay, and poor working conditions. They also highlight the discrepancies b...
How is the Driver's Workload Influenced by the Road Environment?
2017
Abstract This paper focuses on the study of the driver's workload while driving on a rural two-lane road with different traffic flows. The aim of the research is to examine a parameter that could be representative of the driving effort, quite sensible to the external factors that cause disturbance to the regular driving activity. To solve this problem, the authors used a specific instrumented vehicle for monitoring some physiological parameters of the driver (as the eye movements and the Galvanic Skin Resistance), referring their values to the road context. The results are very interesting and confirm that knowing the workload is useful to improve the road safety only if it is related to th…

Novel functionalized cispentacin derivatives. Synthesis of 1,2,3-triazole-substituted 2-aminocyclopentanecarboxylate stereoisomers
2008
Four 1,2,3-triazole-substituted ethyl 2-amino-3-hydroxycyclopentanecarboxylate diastereomers (3,4-disubstituted cispentacins) with a cyclopentane skeleton were prepared in enantiomerically pure form from racemic β-lactam 7 via enzymatic ring opening, epoxidation and selective ring opening of the oxirane ring with sodium azide. The formation of the 1,2,3-triazole ring system involved click chemistry: 1,3-dipolar cycloaddition of the corresponding 4-substituted azidocarboxylates with diethyl acetylenedicarboxylate.
Synthesis of Isoxazole and 1,2,3-Triazole Isoindole Derivatives via Silver- and Copper-Catalyzed 1,3-Dipolar Cycloaddition Reaction.
2016
International audience; The CuI-or Ag 2 CO 3-catalyzed [3+2] cycloaddition of propargyl-substituted dihydroisoindolin-1-one (3) with arylnitrile oxides 1a-d (Ar = Ph, p-MeC 6 H 4 , p-MeOC 6 H 4 , p-ClC 6 H 4) produces in good yields novel 3,5-disubstituted isoxazoles 4 of the ethyl-2-benzyl-3-oxo-1-((3-arylisoxazol-5yl)methyl)-2,3-dihydro-1H-isoindole-1-carboxylate type. With aryl azides 2a-d (Ar = Ph, p-MeC 6 H 4 , p-OMeC 6 H 4 , p-ClC 6 H 4), a series of 1,4-disubstituted 1,2,3-triazoles 6 (ethyl-2-benzyl-3-oxo-1-((1-aryl-1H-1,2,3-triazol-4-yl)methyl)-2,3-dihydro-1H-isoindole-1-carboxylates) was obtained. The reactions proceed in a regioselective manner affording exclusively racemic adduc…
