This article aims to assess whether differences in teacher characteristics vary with differences in socioeconomic compositions of schools. We conducted correlation analyses on administrative data from the French-speaking education system in Belgium. This database regroups more than 20,000 teachers in 1,630 elementary schools. We selected indicators to measure the link between schools’ socioeconomic composition and a set of dimensions of teachers’ profile such as experience, job security, and stability. The results confirm that some of these dimensions are linked to the school composition. The findings highlight the relevance of considering segmentation of the school market when studying the topic. 相似文献

If You're Happy and You Know It: Positive Moods Reduce Age‐Related Differences in False Memory 下载免费PDF全文
When tested in the Deese–Roediger–McDermott paradigm, children typically exhibit fewer false memories than do adolescents or adults. Here, participants’ moods and the valence of word lists were manipulated to explore the mechanism responsible for this developmental reversal in memory performance. Children (7‐ to 8‐year‐olds), adolescents (11‐ to 12‐year‐olds), and young adults (18‐ to 22‐year‐olds; N = 270) were assigned to one of three induced mood conditions and were presented with emotional word lists. In negative moods, adolescents and adults falsely recalled more negative information than did children, showing the typical developmental reversal effect. This effect, however, was eliminated when participants were in positive moods. The findings provide support for associative‐activation theory and have important implications for our understanding of the development of emotional false memories. 相似文献

Time-lapse videos of growing biofilms were analyzed using a background subtraction method, which removed camouflaging effects from the heterogeneous field of view to reveal evidence of streamer formation from optically dense biofilm segments. In addition, quantitative measurements of biofilm velocity and optical density, combined with mathematical modeling, demonstrated that streamer formation occurred from mature, high-viscosity biofilms. We propose a streamer formation mechanism by sudden partial detachment, as opposed to continuous elongation as observed in other microfluidic studies. Additionally, streamer formation occurred in straight microchannels, as opposed to serpentine or pseudo-porous channels, as previously reported. 相似文献

This study investigated the effects of combined sleep deprivation and strenuous exercise on cognitive and neurobehavioral performance among long-distance runners completing one of the most difficult ultramarathons in the world. Seventeen runners participated. Each had a wrist-worn actigraph throughout the race to record their sleep time. In addition, each individual’s performance in 10-min response-time tests before and after the race was recorded and a questionnaire enabled participants to report any difficulties they experienced during the competition. During race completion times of 27 to 44 h, combined acute lack of sleep (12 ± 17 min of rest during the race) and strenuous exercise (168.0 km) had marked adverse effects on cognitive performances ranging from mere lengthening of response time to serious symptoms such as visual hallucinations. This study suggests that regardless of rest duration and time in race, cognitive performances of ultramarathoners are adversely affected. 相似文献

Latin presence in the Middle East came to an end with the fall of Acre in 690/1291. Among the last prisoners, Roger of Stanegrave, who gave testimony of his captivity in Cairo, was released around 715/1315. Therefore, how can we explain that Egyptian chroniclers kept on telling the life and tribulations of “Frankish captives” (asārā min al-Afranj) in Cairo as late as the last decades of the fourteenth century? This article looks first at the conditions of the Latin prisoners in Mamlūk Cairo and at their forced labour on the building sites of the city. It investigates afterwards the astonishing life and business of their descendants, trading wine and dealing with entertainment and prostitution in the city centre of Cairo, before being confronted with repression by Mamlūk authorities and being scattered over the most disreputable areas of the city. The history of Cairo and its urban fabric gives a unique opportunity to bring to light the life of people still referred to as “Frankish captives”, one century after the end of the crusader wars, and to understand how they finally became indigenous. 相似文献

This article is an ethnographic report of the dialectic tension management practices of a community-building organization called the Nehemiah Group. 1 This group unites local churches to serve the community. This three-year participant-observation study documents how group members manage two primary and intertwined dialectic tensions: noncooperation-cooperation and unity-division. Members use multiple practices to manage these tensions and other intertwined tensions: They construct narratives to voice moral issues, to alternate between tension poles to address pragmatic obstacles, to frame tensions as complementary through segmentation, and rely on prayer rituals to reframe tensions. From this analysis, three implications follow: (a) moral narratives serve to construct framing options, (b) a larger discursive history is utilized to create counternarratives, and (c) metadiscursive practices rely on rituals to manage tensions. 相似文献

This study examines how high school students' information literacy (IL) skills prepare them for academic work in the digital age. The project included: (a) an audit of university IL practices; and (b) the administration of the James Madison University (JMU) Information Literacy Test (ILT) to 103 twelfth grade students in Alberta, Canada. Due to the low stakes of the test, there was concern about the reliability of the results. Rapid guessing, response time effort, and motivation filters were applied to confirm the reliability of the results. Results indicate a gap between expectations of high school students and their skills. Using a standardized test, potential incoming undergraduate IL proficiency was identified, including student strengths and weaknesses. The audit identified IL policies and practices at the university, indicating discrepancies in the IL instruction students may receive. Findings indicate that students lack the IL proficiency required to succeed in the post-secondary educational environment, and the libraries are not prepared to effectively address this gap. 相似文献

Increasing attention to affective issues is evident in human information behavior work in library and information science (LIS) as well as in a wide range of other disciplines. However, it is questionable whether the LIS systems-oriented literature reflects any serious interest in affective issues such as emotion or confidence, as these affect information behavior. This study analyzes systems work in LIS to determine the relative interest in affective issues being shown. Content analysis of articles published between 1999 and 2003 indicates that systems work in LIS pays little attention to affective variables. In addition, insufficient intellectual access to affective issues is provided by the primary indexing services. 相似文献
