Domain walls in supersymmetric QCD: The taming of the zoo

2000

We provide a unified picture of the domain wall spectrum in supersymmetric QCD with Nc colors and Nf flavors of quarks in the (anti-) fundamental representation. Within the framework of the Veneziano-Yankielowicz-Taylor effective Lagrangian, we consider domain walls connecting chiral symmetry breaking vacua, and we take the quark masses to be degenerate. For Nf/Ncm** there is no domain wall. We numerically determine m* and m** as a function of Nf/Nc, and we find that m** approaches a constant value in the limit that this ratio goes to one.

Aspects of values in human-technology interaction design : a content-based view to values

Mental contents in interacting with a multiobjective optimization program

2008

User psychology aims at understanding human-machine interaction from a psychological point of view. Its ultimate goal is to provide knowledge about human psychological properties for interaction designers. In this article, we are particularly interested in applying the theoretical concepts of mental contents (i.e., the information contents of users’ mental representations), in studying interaction with professional software. The immediate motivation for adopting such an approach arises from problems met in designing interaction processes in multiobjective optimization software. These types of software are meant to support complex thought and decision-making processes and this is why interac…

The morpheme gender effect.

2008

In three experiments we explored the mental representation of morphologically complex words in French. Subjects were asked to perform a gender decision task on morphologically complex words that were of the same gender as their base or not. We found that gender decisions were made more slowly for morphologically complex words made from a base with an opposite gender compared to words for which the gender of the base matches that of the derived noun. Similar results were obtained for words that are pseudo-morphologically complex while no effect was observed for non-morphological embedded words. Our results suggest that during gender identification of derived and pseudo-derived words, morphem…

Mental Images and School Learning: A Longitudinal Study on Children

2019

Recent literature have underlined the connections between children’s reading skills and capacity to create and use mental representations or mental images; furthermore data highlighted the involvement of visuospatial abilities both during math learning and during subsequent developmental phases in performing math tasks. The present research adopted a longitudinal design to assess whether the processes of mental imagery in preschoolers (ages 4–5 years) are predictive of mathematics skills, writing and reading, in the early years of primary school (ages 6–7 years). The research lasted for two school years; in the first phase, the general group of participants consisted of 100 children, and al…

Improvement of motor performance by observational training in elderly people.

2010

Action observation influences action execution; this strong coupling is underlined by an overlap of cortical areas activated during observation and execution of action, and is dependent of specific motor experience. The goal of the present study was to verify if action observation can be used for rehabilitation of elderly people. We tested this question with a protocol of observational practice of 2 frequently used movements: walking and sit-to-stand/back-to-sit. Both tasks were performed at normal and maximal speed before and after training, by 8 elderly subjects. Observational practice led to an increase in walking velocity via an increase in step frequency, but without modification of st…

The content validity of the adult attachment interview. An empirical investigation using text analysis

2011

The aim of this study was to conduct a preliminary investigation of the content validity of the Adult Attachment Interview (AAI). Content validity is a series of hypothesis control methods relating to the communication of facts and it can be tested using several procedures of analytical decomposition (Rositi, 1988). In order to evaluate the content validity of a text, Sireci (1998), Sireci and Geisinger (1992, 1995), and Ding (2005) suggested the integration within this technique of multidimensional scaling and cluster analysis. The aim of this study was to conduct a preliminary investigation of the content validity of the AAI, as proposed in the literature. We hypothesized that participant…

Processing and learning from multiple sources: A comparative case study of students with dyslexia working in a multiple source multimedia context

2019

This study investigated how four 10th-grade students with dyslexia processed and integrated information across web pages and representations when learning in a multiple source multimedia context. Eye movement data showed that participants’ processing of the materials varied with respect to their initial exploration of the web pages, their overall processing time, and the linearity of their processing patterns, with post-learning interviews indicating the deliberate, strategic considerations underlying each participant’s processing pattern. Eye movement data in terms of fixation duration and percentage of regressions also corroborated the findings of formal, diagnostic assessments. Finally, …

Initial state azimuthal anisotropies in small collision systems

2015

Strong multiparticle azimuthal correlations have recently been observed in high energy proton-nucleus collisions. While final state collective effects can be responsible for many of the observations, the domain structure in the classical color field of a high energy nucleus also naturally leads to such correlations. We describe recent calculations of the momentum space 2-particle cumulant azimuthal anisotropy coefficients v_n{2}, n=2,3,4 from fundamental representation Wilson line distributions describing the high energy nucleus. We find significant differences between Wilson lines from the MV model and from JIMWLK evolution. We also discuss the relation of this calculation to earlier work …

Investigating consumers' representations of beers through a free association task: A comparison between packaging and blind conditions

2013

International audience; Food behavior has been shown to be influenced by top-down processes such as expectations generated from the mental representations of product. Investigating how a product is represented in consumers' mind is therefore essential to a better understanding of food behavior. As traditional and typical products are particularly prone to expectation effects, these products are well suited to explore consumer's mental representations. Among traditional products, beers are certainly of interest for both product development and marketing. A free association task was conducted in two evaluation conditions. Participants were asked to state what came to their mind while evaluati…
