SOCIAL GENDER ROLES IN PERCEPTION OF FEMALE AND MALE POLISH STUDENTS

2019

The aim of the study was to reveal social gender roles in the perception of male and female Polish students. The social gender roles have been examined in the context of cultural consensus.
 The Cultural Models Scenario has been used with 223 participants. The research method is based on series of brief scenarios that were created with an anthropological methodology. After in-depth interviews in Polish society, basic social roles were described in scenarios. In the first phase the group of respondents (N = 104) evaluated the gender social norms in the scenarios. In the second phase the following group with similar socioeconomical characteristic (N = 119) answered the questions while th…

Exploring the Affordances of SimReal for Learning Mathematics in Teacher Education: A Socio-Cultural Perspective

2020

SimReal is an innovative technology that emerged the last few years in mathematics education. It provides new potentialities for mathematical learning by means of dynamic and interactive visualizations of mathematical concepts. This paper uses SimReal in the context of teacher education to explore the affordances and constraints of the tool for the learning of mathematics. It presents a framework that combines Vygotsky’s socio-cultural theory, the role of mediation, and the notion of affordance at a technological, pedagogical, and socio-cultural level. The aim of the article is to explore the extent to which SimReal as a mediating artifact affords students’ mathematical learning in teacher …

Archaeometric analysis of Roman bronze coins from the Magna Mater temple using solid-state voltammetry and electrochemical impedance spectroscopy

2017

Voltammetry of microparticles (VMP) and electrochemical impedance spectroscopy (EIS) techniques, complemented by SEM-EDX and Raman spectroscopy, were applied to a set of 15 Roman bronze coins and one Tessera from the temple of Magna Mater (Rome, Italy). The archaeological site, dated back between the second half and the end of the 4th century A.D., presented a complicated stratigraphic context. Characteristic voltammetric patterns for cuprite and tenorite for sub-microsamples of the corrosion layers of the coins deposited onto graphite electrodes in contact with 0.10 M HClO4 aqueous solution yielded a grouping of the coins into three main groups. This grouping was confirmed and refined usin…

Observation of Kuznetsov-Ma soliton dynamics in optical fibre

2012

International audience; The nonlinear Schro¨dinger equation (NLSE) is a central model of nonlinear science, applying to hydrodynamics, plasma physics, molecular biology and optics. The NLSE admits only few elementary analytic solutions, but one in particular describing a localized soliton on a finite background is of intense current interest in the context of understanding the physics of extreme waves. However, although the first solution of this type was the Kuznetzov-Ma (KM) soliton derived in 1977, there have in fact been no quantitative experiments confirming its validity. We report here novel experiments in optical fibre that confirm the KM soliton theory, completing an important serie…

On real-time algorithms for the location search of discontinuous conductivities with one measurement

2008

We discuss, and compare, two simple methods that provide coordinates of a point in the vicinity of one inclusion within some object with homogeneous electrical properties. In the context of nondestructive testing such an inclusion may correspond to a material defect, whereas in medicine this may correspond to a lesion in the brain, to name only two possible applications. Both methods use only one pair of voltage/current measurements on the entire boundary of the object to determine a single pair of coordinates that is considered to be close to the center of the inclusion. The first method has been proposed previously by Kwon, Seo and Yoon; the second method, called here the effective dipole…

Ausencias relevantes en la teoria del curriculum.

2020

Se señalan en el artículo algunas ausencias significativas sobre el modo en que la teoría se ha venido enfrentando al currículum, con especial énfasis sobre lo ocurrido en el contexto español. La historia política del currículum, la mirada desde estudios culturales, la producción de los regímenes de verdad en el currículum, la falta de problematización de las narrativas modernas que inspiran e impregnan la producción curricular o la oportunidad de considerar la ciudad como currículum son algunos de los aspectos que se comentan. Some significant absences are pointed out in the article about the way in which the theory has been confronting the curriculum, with special emphasis on what happene…

Conceptualizing engagement in the mobile context

2016

This conceptual study answers how engagement is defined and conceptualized in the mobile service/technology context. A systematic literature review was conducted in the fields of business and human-computer interactions to achieve this objective. The 22 studies included in the final analysis are classified into two categories that distinguish the main perspectives of mobile engagement. This study demonstrates that prior research has either conceptualized mobile engagement as a behavioral activity (i.e., using or interacting with mobile service/technology) or has perceived it holistically as customer engagement that occurs in a mobile environment. Based on the analysis, it is proposed that c…

Customer Experience Formation in Online Shopping : Investigating the Causes of Positive and Negative Emotions During a Visit to an Online Store

2020

This study explores customer experience formation in an online shopping context by investigating the causes of customers’ positive and negative emotions during their visit to an online store. Survey data collected from 1786 Finnish online customers was used to identify individuals who experienced strong positive (N = 138) or negative emotions (N = 215) during their visit. The causes of negative and positive emotions were studied by analyzing customers’ open-ended, written explanations attributed to their emotions. Attribution theory is utilized to explain how individuals make sense of their emotions. The findings show that customers offer various explanations for the emotions evoked during …
