Synthesis, characterization, and catalytic activity of functionalized metal Bis(thiosemicarbazones).
Bis-(thiosemicarbazones) are a class of ligands that have found a wide range of uses from electrocatalysts to medicinal and diagnostic reagents. These ligands contain a diimine backbone, N2S2 chelating core, and pendent amines. In order to further explore this class of ligands, the previously underreported transamination reaction, which exchanges one pendent amine group for another, was utilized to create several derivatives using aliphatic and aromatic amines. The transamination reaction is appealing alternative to making the desired thiosemicarbazide. Further appeals come from the fact that it is a one-pot reaction that gives highly pure products in good yields. Product yields were improved as varying reaction conditions and solvents. One of these newly transaminated species that contained hindered amine bases were then treated with nickel(II) and copper(II) salts resulting in the corresponding metal complexes. These complexes were then alkylated to create charged pendent frameworks. Subsequently, both the charged and free base metal complexes were tested for homogeneous HER activity. It was observed that the free base complexes were the most active due to a proposed proton relay mechanism involving the pendent amine groups. The charged species did display an anodic shift in the onset potentials, however they were found to be less active as HER catalysts. Heterogeneous studies were conducted with NiATSM on p-Si electrode surfaces. Initial films were form by drop casting an acetonitrile solution of NiATSM followed by evaporation. The films were found to peel off after a short period of time during HER studies in 0.5 M H2SO4 as the acid source. To stabilize the film, a Nafion solution (5% w/v) was drop casted over the NIATSM film and evaporated in an oven for 15 minutes prior to use in HER studies. With this, there was no drop off in activity of the catalytic film. The photo indued HER studies for NiATSM indicated that it was a viable material with low onset potential needed
Letter from Calvary Morris to James B. Finley
Calvary Morris, U.S. Representative from Ohio, writes about his involvement in the M.E. society in Washington City. When not at the Capitol, Morris\u27 primary associations are with members of the society. A group of members from Congress meet every Saturday night for a prayer meeting.

The Promise of Character Education in Middle School: A Meta-Analysis
Early adolescence is a developmental stage characterized by changes in reasoning, social cognition, and desire for autonomy in youth aged 11-14 (or grades 6-8). This period is also associated with heightened impulsivity and risk-taking that has been linked to school-related challenges such as antisocial behaviors and declining grades. Character education, a particular brand of social-emotional practice, has been promulgated as a developmentally responsive program that can promote prosocial behavior and academic success by building upon existing developmental strengths. However, research findings to date are primarily informed by elementary school program outcomes. Due to this limitation, a meta-analytic review of recent research on middle school character education programs and interventions was completed. Findings demonstrate positive associations between character education and academic and behavioral success, as well as social and internal perceptions
Des Styles pour une Personnalisation de l'Interaction Homme-Robot
Les robots compagnons sont des robots personnels qui ont pour objectif dâaccompagner lâutilisateur dans ses activiteÌs de la vie quotidienne. Nous nous inteÌressons pour notre part aux enfants, accompagneÌs par un robot dans diffeÌrentes situations : travail scolaire, reÌconfort, jeu, protection,...LâacceptabiliteÌ de ces robots compagnons dans le quotidien est questionneÌe dans de nombreux travaux ; elle est lieÌe aÌ son apparence physique, son utiliteÌ, sa faciliteÌ dâutilisation mais aussi aÌ dâautres criteÌres quâil reste aÌ eÌtudier. Un des deÌfis dans la conception de tels robots est de les doter de reÌelles compeÌtences sociales de perception, de raisonnement et dâaction lors de leurs interactions avec lâutilisateur. La recherche dans le domaine de lâinteraction humain- robot se tourne ainsi de plus en plus vers les travaux en Informatique Affective (Affective Computing) pour concevoir des robots personnels plus sociaux, lâeÌmotion eÌtant une dimension centrale dans les interactions.Dâautres dimensions comme la confiance, la leÌgitimiteÌ ou encore la creÌdibiliteÌ du compagnon sont importantes pour leur acceptabiliteÌ. Des travaux ont proposĂ© lâideÌe dâun compagnon âpolyvalentâ capable dâendosser de multiples roÌles et de sâadapter en fonction des besoins de lâutilisateur et en fonction du contexte de la situation. La TheÌorie du Compagnon preÌsenteÌe souleÌve la question des diffeÌrences entre individus influençant la qualiteÌ de lâinteraction et la construction dâune relation entre le compagnon et lâutilisateur. Ce travail sur la personnalisation des robots a pour but de creÌer de la valeur, en particulier pour des parents souhaitant un robot compagnon pour leur enfant, en accord avec leurs propres attentes
Plasticité des Interfaces par Perception de l'Interaction Homme-Machine : illustration en oculométrie
International audienceAujourd'hui, les efforts en plasticité des IHM ont principalement porté sur les méthodes de conception. Or, l'utilisation en ligne d'informations sur les perceptions de l'utilisateur est une source d'informations intéressantes pour la plasticité : elle permettrait une adaptation à la volée de l'IHM pour mieux l'ajuster à l'humain. Pour montrer la pertinence et la faisabilité de l'approche, nous avons réalisé un démonstrateur d'une IHM plastique s'adaptant, en ligne, en fonction des interactions (actions et perceptions) de l'utilisateur
Towards a framework for adaptive web applications
We have developed a framework to support adaptive elements in Web pages. In particular we focus on adaptive menus. Developers are able to define rules for menu adaptation according to the features of the device and browser in use. This paper briefly describes the selected adaptation patterns and their implementation.This work is funded by ERDF - European Regional Development

Persuasion technologique et Energie : revue critique de lâĂ©tat de lâart
International audienceThis paper presents a state of the art and an analysis of existing works dedicated to persuasive technologies for energy consumption. Thanks to a systematic analysis, a set of concepts of persuasion has been identified and organized into a six dimensional design space. In particular, the concept of persuasion function is identified and defined. Six persuasion functions are identified: Mirror, Explain, Recommend, What-if, What-for, Suggest-and-Adjust. This design space is used to characterize the works considered in this state of the art.Cet article dresse un Ă©tat de lâart et une analyse critique des travaux menĂ©s sur la persuasion technologique dans le cadre de la consommation Ă©nergĂ©tique. De cette analyse systĂ©matique est extrait un panel des concepts de persuasion ensuite organisĂ© au sein dâun espace de classification comportant six dimensions dont le concept de fonction de persuasion. En particulier, six fonctions de persuasion sont identifiĂ©es et caractĂ©risĂ©es : Mirror, Explain, Recommend, What-if, What-for, Suggest- and-Adjust. Cet espace de classification permet de caractĂ©riser les travaux de lâart
