As an economical and feasible intervention, reflection demands learners using critical thinking to examine presented information, questioning its validity, and drawing conclusions based on the resulting ideas during a learning process. The aim of this study is to gain insight into the effects of practicing short, frequent and structured reflective breaks that are interspersed with the reading process of a learning material. It tries to reveal whether physiological signals can be used as appropriate indicators to reveal the actual changes of cognitive states while introducing different reflective breaks during learning. The recorded physiological signals include skin temperature, blood volume pulse, pulse volume amplitude, and pulse rate. The results show that while these embedded “reflection rituals” did not affect learners’ performance they had significantly impact on time on task, perceived learning and those learners' physiological (cognitive) states. Physiological data returned significant differences between the reading and reflection activity. Measurements of temperature and pulse rate are lower when covering the course equipped with additional reflection affordances while blood volume pulse and pulse volume amplitude are higher. In addition, applying statistics analysis to the physiological data exhumes significant differences between different types of reflection activities for those measurements including skin temperature, pulse volume amplitude and pulse.

Measuring reliable feet trajectories is needed in many applications. This paper provides the principles used in GAIMS, which is a non-intrusive system that measures feet trajectories based on multiple range laser scanners. We present the technical challenges that we had to address, as well as an overview of the implemented processing pipeline of GAIMS. [less ▲]

This study specifically addresses the question of how associative networks contribute to brand image perception measurement to segment the market more effectively, as well as to demonstrate brand image impairment. Carried out using surveys and experimental designs, this dissertation is positioned as part of the research stream on the use of associative networks in marketing, and particularly consumer mapping. Firstly, this study provides clear arguments for using brand concept maps (BCM) as highly suitable method to capture the complete brand image and segment the market based on brand perception. Secondly, thanks to BCM, the present research provide empirical evidences on the likelihood of brand image confusion, namely the dilution of attributes and the creation of unattractive associations, as a result of the introduction of a new brand. Thirdly, BCM captures the effect of exposure to negative user-generated content on the likelihood of doppelganger brand image, namely the appearance, or reinforcement, of negative associations at the brand reputation level. This work reveals that BCM is a superior approach to measure brand image and brand reputation, compared to dyadic methods. In addition, it broadens the applications of associative networks in marketing. Moreover this research shows how consumers and competitors may influence the brand image. Besides this scientific output, this research aims in providing brand mangers with an effective method to monitor and capture brand image and brand reputation. [less ▲]

The scarcity of internal loss databases tends to hinder the use of the advanced approaches for operational risk measurement (Advanced Measurement Approaches (AMA)) in financial institutions. As there is a greater variety in credit risk modelling, this article explores the applicability of a modified version of CreditRisk+ to operational loss data. Our adapted model, OpRisk+, works out very satisfying Values-at-Risk (VaR) at 95% level as compared with estimates drawn from sophisticated AMA models. OpRisk+ proves to be especially worthy in the case of small samples, where more complex methods cannot be applied. OpRisk+ could therefore be used to fit the body of the distribution of operational losses up to the 95%-percentile, while Extreme Value Theory (EVT), external databases or scenario analysis should be used beyond this quantile.

With the emergence of positive psychology, research interest in workers positive responses to work conditions has gained ground fast. In the beginning of the 21st century, our unit developed the PNOSI, a new tool for measuring Positive and Negative Occupational Stress. Negative occupational stress was defined as the response of workers facing demands they feel they have to manage but for which they doubt necessary resources are available. Positive occupational stress was defined as the response of workers facing demands they feel they have to manage and for which they perceive necessary resources are available. Exploratory analyses (Barbier & Hansez, 2008) have identified a two-factor structure, one measuring Positive Occupational Stress (POSI) and the other measuring Negative Occupational Stress (NOSI). The following research has two goals: establishing PNOSI intern structure through a cross-validation strategy using calibration and validation samples (goal 1), and testing its convergent and discriminant validity (goal 2). As regards to goal 1, structural equation modelling using Lisrel 8.80 was performed on 2,713 data collected in a Belgian electricity company. Results show that the two-factor solution suits data best than an alternative one “wellbeing” factor solution. Moreover, eliminating two items leads to better fit. We then fitted this reduced two-factor structure on more than 15,000 data collected in six companies. Results show that the reduced two-factor solution should be preferred to the alternative one in all six samples. PNOSI intern structure is thus replicated. As regards to goal 2, we calculated correlations between NOSI and POSI scales, and constructs of burnout, engagement, workaholism and commitment. Data were collected in a Belgian public institution (N = 954). NOSI was moderately correlated to our burnout measure, and can thus be considered as a different, even if related, construct. POSI was highly correlated to our measure of engagement, challenging our hypothesis that the two are different constructs. Finally, NOSI was moderately and negatively correlated to commitment and positively correlated to workaholism, whereas the reverse was true for POSI. It seems thus that NOSI is distinct from burnout, workaholism and commitment, whereas POSI is distinct from workaholism and commitment. To conclude, we can say that PNOSI two-factor structure is established. NOSI shows convergent validity with the similar construct of burnout, but is distinct from it. Results are less clear concerning POSI and engagement. Finally, NOSI and POSI are differently related to constructs of commitment and workaholism; their discriminant validity is thus established.

This article reports on the validation of the Positive and Negative Occupational States Inventory (PNOSI), a new tool for measuring positive and negative occupational states. Three goals were defined: testing the structural validity of the PNOSI, testing its stability, and testing its convergent and discriminant validity with engagement, burnout, commitment, and workaholism. Data were collected in seven different companies (more than 16,000 participants). The factorial validity of the PNOSI was demonstrated using covariance structure analyses. A two-factor model with a negative occupational state factor and a positive occupational state factor fitted the data better than an alternative one-factor model. The two corresponding scales demonstrated good internal consistency. The results confirmed that positive and negative occupational states are distinct constructs and should be measured with different items. Convergent and discriminant validity with related constructs, such as engagement, burnout, commitment, and workaholism, were also demonstrated. The conclusion is that the PNOSI has good psychometric properties. [less ▲]
