The Reason of Imagination. The Blazing Worlds of Margaret Cavendish and Siri Hustvedt
2020
One of the peculiarities of 17th and 18th centuries literature is the link between knowledge and imagination, a relationship in which narration sometimes accompanies science, sometimes goes beyond it. The idea of imagination as a true means of knowledge is the subject of Margaret Cavendish’s best known work, The Blazing World (1666), where her alter ego is free to built a whole social and philosophical system based on corporality and subjectivity. From the same conception of imagination starts Siri Hustvedt when in 2014 rewrites The Blazing World: the story of an artist who still in the twentieth century tries to face the overwhelming misogyny with the performance of the body and the theory…
Dy159 Electron-Capture: A New Candidate for Neutrino Mass Determination
2021
International audience; The ground state to ground state electron-capture Q value of Dy159 (3/2-) has been measured directly using the double Penning trap mass spectrometer JYFLTRAP. A value of 364.73(19) keV was obtained from a measurement of the cyclotron frequency ratio of the decay parent Dy159 and the decay daughter Tb159 ions using the novel phase-imaging ion-cyclotron resonance technique. The Q values for allowed Gamow-Teller transition to 5/2- and the third-forbidden unique transition to 11/2+ state with excitation energies of 363.5449(14) keV and 362.050(40) keV in Tb159 were determined to be 1.18(19) keV and 2.68(19) keV, respectively. The high-precision Q value of transition 3/2-…
A meta-analysis of the relation between RAN and mathematics.
2017
Several studies have shown that rapid automatized naming (RAN) is a significant predictor of mathematics, but the nature of their relationship remains elusive. Thus, the purpose of this meta-analysis was to estimate the size of their relationship and determine the conditions under which they correlate. We used a random-effects model analysis of data from 38 studies (33 unique samples, 151 correlations, 7,135 participants) to examine the size of the RAN–mathematics relationship and the role of different moderators (i.e., math measure and variable, type of RAN task, math age, study design, and sample characteristics). The results showed a significant correlation between RAN and mathematics (r…
Effect of Stacking Sequence and Sodium Bicarbonate Treatment on Quasi-Static and Dynamic Mechanical Properties of Flax/Jute Epoxy-Based Composites
2019
The present paper deals with the investigation of quasi-static and dynamic mechanical response of epoxy-based composites reinforced with flax and/or jute plain weave fabrics. In order to evaluate the influence of the stacking sequence, two monolithic laminates reinforced with flax or jute fibers and two hybrid flax/jute laminates were manufactured through the vacuum infusion technique. Furthermore, an eco-friendly and cost-effective surface treatment based on fiber soaking in a sodium bicarbonate solution was employed to improve the fiber-matrix adhesion. The mechanical characterization (by means of quasi-static flexural, dynamic mechanical thermal analysis and Charpy impact tests) allowed …
Best Friends Forever? Modeling the Mechanisms of Friendship Network Formation
2020
The formation of friendships and alliances is a ubiquitous feature of human life, and likely a crucial component of the cooperative hunting and child-rearing practices that helped our early hominin ancestors survive. Research on contemporary human beings typically finds that strong-tie social networks are fairly small, and reveals a high degree of physical (e.g., age) and social-structural (e.g., educational attainment) homophily. Yet, existing work all too often underestimates, or even ignores, the importance of abstract, symbolic homophily (such as shared identities or worldviews) as a driver of friendship formation. Here we employ agent-based modeling to identify the optimal variable wei…
Experiencing anger in a social interaction: The role of personality
2018
Abstract Although prior research has shown a relationship between the Big Five personality factors and trait anger, evidence that links these personality traits to the experience of state anger is rare. The current study investigated the effect of the Big Five personality traits on the state anger experience after a provocation in a staged social interaction and how status differences moderate these personality effects in an academic sample. In the equal status condition (N = 131, 56% female, aged 18 to 37) participants were provoked by a confederate; in the low status condition (N = 125, 55% female, aged 18 to 51) anger was instead provoked by the experimenter. In both conditions, individu…
Cultural Interpretations of Global Information? Hindsight Bias after Reading Wikipedia Articles across Cultures
2017
Summary: Hindsight bias is the mistaken belief that an outcome could have been foreseen once it is known. But what happens after learning about an event? Can reading biased media amplify hindsight distortions? And do people from different cultural backgrounds — with different cognitive thinking styles — draw equal conclusions from equal media reports? We report two studies with Wikipedia articles and samples from different cultures (Study 1: Germany, Singapore, USA, Vietnam, Japan, Sweden, N = 446; Study 2: USA, Vietnam, N = 144). Participants read one of two article versions (foresight and hindsight) about the Fukushima Nuclear Plant and estimated the likelihood, inevitability, and foresee…
Debiasing media articles–reducing hindsight bias in the production of written work.
2021
Written work such as Wikipedia articles can contain hindsight bias. Since reading biased texts can, in turn, increase recipients’ individual hindsight bias, it is an important agenda to examine effective debiasing strategies. In the present study (N = 164), we tested whether providing authors with debiasing strategies can effectively reduce hindsight bias in their content. Specifically, participants wrote an article based on several newspaper articles about a dam and we manipulated whether they received event knowledge (i.e., dam collapse) and a debiasing intervention. Ten blind coders rated the extent to which the produced articles were suggestive of the disaster. Debiasing was successful …
Spanish versión of the Short Depression-Happiness Scale (SDHS): A Reliability and Validity study in a simple of Spanish elderly people
2018
The psychometric properties of the Short Depression-Happiness Scale (SDHS) were analyzed in a sample of 216 Spanish elderly people with an average age of 73.89 (SD = 6.49). An exploratory factor analysis and confirmatory factor analysis were developed in order to identify the factorial solution and the best model fit. Just on factor was identified. Regarding reliability and validity, internal consistency index was .757 and the correlation between the Short Depression-Happiness Scale (SDHS) and measures of others construct, General Health Questionnaire (GHQ) and Center for Epidemiological Studies Depression Scale (CESD) (CESD), were significance. The practical implications of the scale and…
Impact of text availability and question format on reading comprehension processes
2017
Abstract We conducted two experiments to analyze how text availability and question format affect readers’ processes and performance on measures of expository text reading comprehension. Junior high school students read expository texts and answered both multiple choice and open-ended questions on a computer that recorded reading times and readers’ actions with Read&Answer software. The results showed that readers reread prior text segments during initial reading of the text more often when they knew that the text would be unavailable when answering questions than when they knew that the text would be available. In addition, readers made more search decisions in the text- available conditio…
