The three wives problem and Shapley value
2015
We examine the Talmudic three wives problem, which is a generalization of the Talmudic contested garment problem solved by Aumann and Maschler (1985) using coalitional procedure. This problem has many practical applications. In an attempt to unify all Talmudic methods, Guiasu (2010, 2011) asserts that it can be explained in terms of “run-to-the-bank”, that is, of Shapley value in a “cumulative game”. It can be challenged because the coalitional procedure yields the same result as the nucleolus, which corresponds to a “dual game”. As Guiasu's solution is paradoxical (it has all the appearances of truth), my contribution consists in explaining the concepts, particularly truncation, that play …
“I feel many contradictory emotions” : Finnish mothers' discursive struggles with motherhood
2022
Objective The aim of the study was to facilitate the understanding and interpretation of multiple aspects of working with mothers by examining Finnish mothers' mothering discourses and the interplay among these discourses. Background According to relational dialectics theory, discourses are systems of meaning that are coproduced in interaction. Although discursive research on motherhood has identified various discourses, research on the interplay among competing motherhood discourses is in its infancy. Method Qualitative questionnaire data from 479 Finnish mothers of infants were analyzed using contrapuntal analysis. Mothers' responses to three open-ended questions were analyzed inductively…
“Kun pääsee irti pulpetista, niin kummasti asiat menevät paremmin perille”: teachers' perspectives of effective teaching strategies for students with…
2015
Inklusiivinen opetus on yleistymässä suomalaisissa kouluissa myös vieraan kielen tunneilla. Oppilaiden hyvin erilaiset taitotasot luovat opettajalle haasteen toteuttaa kaikille sopivaa opetusta samassa tilassa. Lisäksi erilaiset oppimisvaikeudet tulisi ottaa huomioon opetusta suunniteltaessa ja toteuttaessa. Tämän tutkimuksen tarkoituksena oli selvittää laadullisen kyselytutkimuksen avulla suomalaisten vieraan kielen opettajien käyttämiä sekä tehokkaaksi kokemia opetusmenetelmiä. Tutkimuksen aineisto koostuu kyselytutkimuksen vastauksista. Kyselyyn vastasi 32 vieraan kielen opettajaa eri puolilta Suomea. Tuloksia verrattiin muutamaan tutkimuskirjallisuudessa yleisesti tehokkaaksi todettuun …
Consistency tendency and the theory of planned behavior : a randomized controlled crossover trial in a physical activity context
2020
Objective: This study examined the effects of consistency tendency on the predictive power of the theory of planned behavior (TPB) in relation to physical activity behavior. Methods: In this randomized controlled cross-over trial, we recruited 770 undergraduate students from Indonesia who were randomly assigned into two groups. Participants completed physical activity versions of TPB measures at T1 (baseline) and T2 (post 1 week), and the International Physical Activity Questionnaire at T3 (post 1 month). At T1 and T2, the TPB questions were either presented in ensemble-order (i.e., consistency tendency supressed) or alternate-order (i.e., consistency tendency facilitated). Results: The par…
Digital and Interactive Learning and Teaching Methods in Descriptive Geometry
2013
Abstract During the course of “Fundamentals and applications of Science of Representation - Geometric drawing” (held at the Faculty of Engineering at the University of Palermo) we successfully tested the adoption of informatics tools to enhance the comprehension and the critical analysis of complex figures in the geometrical space. The peculiarity in the teaching methodology was the adoption of interactive software products (Cabri Geometre and GeoGebra concerning dynamic and geometrical constructions; the well-known Rhinoceros plug-in, Grasshopper, about generating algorithms; Linceo regarding implementing the graphic display of complex solids in augmented reality). According to our experie…
Assortment, but not knowledge of assortment, affects cooperation and individual success in human groups
2017
The success or failure of human collective action often depends on the cooperation tendencies of individuals in groups, and on the information that individuals have about each other's cooperativeness. However, it is unclear whether these two factors have an interactive effect on cooperation dynamics. Using a decision-making experiment, we confirm that groups comprising individuals with higher cooperation tendencies cooperate at a higher level than groups comprising individuals with low cooperation tendencies. Moreover, assorting individuals with similar cooperation tendency together affected behaviour so that the most cooperative individuals tended to cooperate more and the least cooperativ…
Estimation of the mechanical properties of the eye through the study of its vibrational modes.
2017
Measuring the eye's mechanical properties in vivo and with minimally invasive techniques can be the key for individualized solutions to a number of eye pathologies. The development of such techniques largely relies on a computational modelling of the eyeball and, it optimally requires the synergic interplay between experimentation and numerical simulation. In Astrophysics and Geophysics the remote measurement of structural properties of the systems of their realm is performed on the basis of (helio-)seismic techniques. As a biomechanical system, the eyeball possesses normal vibrational modes encompassing rich information about its structure and mechanical properties. However, the integral a…
A cross-cultural study using Napping (R): Do Korean and French consumers perceive various green tea products differently?
2013
http://www.elsevier.com/locate/foodres ; WOS:000323239400065; International audience; With the increasing demands of global trading, interests in cross-cultural comparisons have increased to gain understanding in the differences of sensory perception and consumer acceptability. The objective of this study was to compare the differences in perception by Korean and French consumers of green tea produced in Korea, China, and Japan, using Napping (R) followed by ultra flash profile. In addition, overall acceptability was examined in both countries. The results of Napping (R) showed that the Korean consumers were able to discriminate the green teas according to their origins and processing metho…
