Regulating the blink: Cognitive reappraisal modulates attention
2014
Our brain is unable to fully process all the sensory signals we encounter. Attention is the process that helps selecting input from all available information for detailed processing and it is largely influenced by the affective value of the stimuli. This study examined if attentional bias towards emotional stimuli can be modulated by cognitively changing their emotional value. Participants were presented with negative and neutral images from four different scene-categories depicting humans (‘Reading’, ‘Working’, ‘Crying’ and ’Violence’). Using cognitive reappraisal subjects decreased and increased the negativity of one negative (e.g., ‘Crying’) and one neutral (e.g., ‘Reading’) category res…
Do Children Cooperate Conditionally?:Adapting the Strategy Method for First-Graders
2020
We develop a public goods game (PGG) to measure cooperation and conditional cooperation in young children. Our design addresses several obstacles in adapting simultaneous and sequential PGGs to children who are not yet able to read or write, do not possess advanced abilities to calculate payoffs, and only have a very limited attention span. It features the combination of haptic offline explanation, fully standardized audiovisual instructions, computerized choices based on touchscreens, and a suitable incentive scheme. Applying our experimental protocol to 129 German first-graders, we find that already 6-year-olds cooperate conditionally and that the relative frequency of different cooperati…
Ethics of Beliefs
2017
This paper deals with the concept of positive learning (PL). The main goal is to provide a working definition of PL on which further refinements and extensions can be based. First, I formulate a list of desiderata for a definition of PL: I argue that a working definition of PL should (i) make the involved epistemic norms explicit, (ii) be flexible, and (iii) be empirically tractable. After that, I argue that a working definition of PL should focus on three basic epistemic norms (which I call Evidentialism, Degrees of Plausibility, and Non-Arbitrary Updates). Drawing on work on the ethics of belief and Bayesian inference, I highlight theoretical and empirical challenges that already follow f…
A sequence motif enriched in regions bound by the Drosophila dosage compensation complex
2010
Abstract Background In Drosophila melanogaster, dosage compensation is mediated by the action of the dosage compensation complex (DCC). How the DCC recognizes the fly X chromosome is still poorly understood. Characteristic sequence signatures at all DCC binding sites have not hitherto been found. Results In this study, we compare the known binding sites of the DCC with oligonucleotide profiles that measure the specificity of the sequences of the D. melanogaster X chromosome. We show that the X chromosome regions bound by the DCC are enriched for a particular type of short, repetitive sequences. Their distribution suggests that these sequences contribute to chromosome recognition, the genera…
Economic Returns to Education in France: OLS and Instrumental Variable Estimations
2013
En ligne sur : http://121.52.153.179/JOURNAL/LJE%20VOL%2018-2/Bhatti,%20Bourdon%20and%20Aslam.pdf; International audience; This article estimates the economic returns to schooling as well as analyzing other explanatory factors for the French labor market. It addresses the issue of endogeneity bias and proposes two new instruments for use in the instrumental variable two-stage least squares technique. Our results show that the proposed instruments are relevant and adequate, based on evidence from the available literature. After using the proposed instruments, we find that the OLS coefficients for schooling are biased downwards. Finally, we choose between the two proposed instruments.
Urban drinking and driving:comparison of electric scooter and bicycle related accidents in facial fracture patients
2022
In recent years, electric scooters (e-scooter) have emerged as an alternative mode of urban transport due to their availability and effortless use. However, e-scooter-related trauma and injuries, especially to the head, have received wide media coverage and raised public concern about their safety. We aim to determine and compare clinically relevant variables, incidence, and severity between bicycle and e-scooter-related facial fractures and potential protective measures for injury prevention. This retrospective study comprised all patients admitted to a tertiary trauma center with bicycle or e-scooter-related facial fractures between January 2019 and October 2020. Patient- and injury-relat…
Le score de propension : un guide méthodologique pour les recherches expérimentales et quasi expérimentales en éducation
2016
La méthode du score de propension devient de plus en plus populaire pour estimer les effets causaux d’un programme d’intervention. Si les applications empiriques de cette méthode sont encore rares dans les recherches en éducation, des exemples de son utilisation se trouvent aisément dans d’autres disciplines. Cependant, sa mise en place soulève plusieurs questions. L’objectif de cet article est de fournir des éléments de réponses guidant le chercheur et l’évaluateur du domaine de l’éducation pour l’estimation et l’utilisation du score de propension. Les différentes étapes de son application sont présentées pas à pas : évaluation du biais de sélection, construction du score de propension et …
Dimensions of the Relationship between the Individual and Her Unique Worldview Construction
2021
Each individual constructs his own private worldview using elements from established worldview traditions. The biographical character of this formation makes this the individual’s “Unique Worldview Construction” (UWC). The purpose of this theoretical study is to analyse the dynamic relationship between the individual and her own UWC. It describes more how than what he believes in or denies. The variation is exceedingly complex. To make it accessible, the complexity is crystallized into seven dimensions: (1) The authority structure deals with the individual’s perception of herself as being superordinate/subordinate to her own UWC. (2) The importance dimension analyses the span from indiffere…
Kako budući stručnjaci u sportu, tjelovježbi i tjelesnome odgoju percipiraju tjelesni izgled pretile djece
2010
Anti-fat bias has been previously identified amongst practising obesity health care specialists, physical education (PE) teachers and students of exercise science and PE in samples in the USA and New Zealand. The present research investigated the perceptions of the physical self of ‘fat’ versus ‘normal-weight’ children held by 167 students studying sport exercise and PE related programmes in higher education in England. Onesample t-tests identified that the sample held negative perceptions towards ‘fat’ children (identified by subscale mean scores that were significantly different from the subscale mean of 2.5 that would identify equivocal perception between ‘fat’ and ‘normal-weight’ childr…
CORPORATE GOVERNANCE AND BEHAVIORAL FINANCE: FROM MANAGERIAL BIASES TO IRRATIONAL INVESTORS
2014
Corporate governance is concerned about the ways in which investors assure themselves of getting a return on their investment, on one hand, and is focus on motivating managers to increase the company profit, on the other hand (the agency theory). Corporate governance emerges from the interaction between managers and investors. Managers are often more likely to invest the extra cash-flow or profit than to return it to shareholders. But, both managers and investors are lees then fully rational. Sometimes their behavior is based on cognitive psychology. In this context, we are dealing with two problems: managerial biases and irrational investors. Managerial biases focus on the illusion of opti…
