Impact of question-answering tasks on search processes and reading comprehension

This study examined the effect of (a) high- and low-level questions and (b) reading the text before the questions asked on performance, delayed text recall, and deep text comprehension, as well as on specific text-inspection patterns. Participants were 37 undergraduate students who answered either high- or low-level questions using the software Read&Answer to read and answer questions on the computer screen. Additionally, half of the sample read first a text and then answered the questions (reading-first condition), whereas the other half answered the questions without having read the text in advance (no-reading-first condition). All participants had the text available to search for the answer. Results indicated that high-level questions facilitated deep comprehension but not immediate performance or delayed recall of text, independently of the reading condition, and that high- and low-level questions differentially affected text-inspection patterns.     

Gender Verifications in Sport: From an East/West Antagonism to a North/South Antagonism

This paper aims to analyze gender verifications in sport from a socio-historical approach. These medical controls intended to keep men from competing in women's international competitions. Some female athletes are put through a masculinization trial, because of morphologies and performances judged as too masculine. Facing these athletes who disrupt the representation of a binary construction between the male sex and the female sex, sports institutions attempt to maintain a sexual bi-categorization. More precisely, this paper will present the ‘symbolic’ suppression of tests since 2000. Thereafter, authorities only rely on an aesthetic and visual assessment of female bodies and no longer use tests in a systematic and obligatory fashion. This reveals the moving boundary subjectively plotted between the masculine and the feminine, which become all the more blurred when the ‘race and class markers’ interfere with the ‘sex markers’.     

User experience of government documents: A framework for informing design decisions

People still use documents in many everyday government processes. From tax payments to passport requests, citizens have to interact with low-interactivity information artifacts such as reports, maps and datasets, among many others. Despite efforts to improve information delivery in the public sector, effective information usage remains a critical topic of action and research. The user experience of government documents has rarely been assessed, despite them being regularly published and frequently used. Considering this, the two following research questions arise: 1) How can government documents be classified (or grouped) in terms of user experience? 2) How can the user experience of government documents be monitored over time in order to inform design decisions? Working with a public agency in Chile, we develop and test a classification and monitoring framework based on two online surveys (N?=?338 and N?=?298). We then propose a framework for understanding user experience of government documents in these three dimensions: interaction goal, volume of information and ease of understanding. Using a graphical representation to classify user experience provides greater visibility of the current status of information produced by a public organization. Furthermore, by monitoring the user experience of a government document at different times, organizations can understand the effect of their design decisions and improve their service quality by implementing user-centered processes.     

Red pigment production by Penicillium purpurogenum GH2 is influenced by pH and temperature

The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture of Penicillium purpurogenum GH2, using Czapek-Dox media with d-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demonstrates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L).     

Suprasegmental Phonology Development and Reading Acquisition: A Longitudinal Study

Previous studies implicate suprasegmental phonology in reading acquisition. However, little is known about how suprasegmental sensitivity develops or how it contributes to reading. Here, 130 Spanish primary-school children participated in this 2-year longitudinal study. Nonlinguistic rhythm, lexical-stress sensitivity and metrical-stress sensitivity, along with phonological awareness, vocabulary, nonverbal intelligence, and reading aloud, were assessed on five occasions. Results suggest that prosody abilities have different developmental trajectories and that prosody explains unique variance in reading beyond that explained by other factors. There was some evidence that the contribution of each prosody skill occurred at different phases in reading development. Nonlinguistic rhythm, lexical-stress sensitivity, and metrical-stress sensitivity assessed at the end of kindergarten, the start of Grade 1, and the end of Grade 1, respectively, predicted reading performance 6 months later. Nevertheless, sample size and reliability temper the conclusions that can be made. The implications of prosody skills for literacy development are discussed.     

Los Sentimientos,Luchas, y Esperanzas de Cinco Familias Mexicana: The Sentiments,Struggles, and Hopes of Five Mexican Families

Within the everyday space of their modest trailer homes, I observed compelling environments in the households of 5 Mexican families. In their homes, there existed los padres con sus hijos (parents with their children) who intuitively expressed cariño, or love, for one another, conversed in multiple languages, practiced cultural traditions, and inculcated hope in their children’s minds and hearts. As I listened to their steadfast voices and felt their innermost emotions, a clearer understanding came to mind about ways in which educators and families might construct new alliances for the benefit of children’s future in America.
