To tell a story,to write it: developmental patterns of narrative skills from preschool to first grade

In this 1-year longitudinal study, the authors explored the development of narrative skills between the oral and written form. The authors aimed to assess the predictive power of textual narrative competence on early narrative text writing skills taking into account the impact of spelling ability. Eighty children (M age?=?5.3 years, age range?=?4.9–5.7 years; SD?=?0.29) were followed longitudinally until entering the first grade of primary school. During kindergarten, they were tested with an oral story production task and in first grade with a written story production task. Narratives were evaluated in terms of structure, cohesion and consistency. In the first grade, children were also submitted to a dictation task to evaluate their spelling competence. Repeated measures ANOVAs were performed in order to examine narrative competence development, also considering gender differences, and regression analyses were implemented to evaluate the predictive capability of textual abilities expressed by oral narratives on textual abilities expressed by writing. The results showed some significant differences when scores in kindergarten were compared to scores in primary school. Moreover, the ability to tell well-structured, cohesive and consistent stories predicts the ability to write stories with the same qualities in the sample of participants without spelling difficulty. Instead, the predictive link is not apparent considering those children with difficulties in orthographic ability. This research allows us to reflect about how the medium of writing might interfere, on the basis of the level of mastery, with the opportunity to express narrative skills in the transition from the oral to written code. The central role of writing instrument functionality opens the way to practical implications.     

After conflict comes education? Reflections on the representations of emergencies in ‘Education in Emergencies’

Over the last decade, education has been advanced as a new and legitimate core of the humanitarian crisis response. ‘Education in Emergencies’ (EiE) developed into an institutionalised field of humanitarian practice, advocacy, and scholarly work. Identifying how emergency discourses have been critiqued to operate as ‘social imaginaries’, in this paper the ‘emergency imaginary’ as it develops in the particular discursive context of EiE is analysed. We scrutinise how emergencies are represented in this EiE-discourse by pointing to the socio-ideological and economic drivers of conflict, how the interconnections between education and these drivers are pictured, and the educational changes subsequently advocated for. We conclude that, while EiE has been called a ‘new field of academic and policy research’, the discourse might reiterate prevailing power relations, leading to an adverse portrayal of crisis-affected communities and a legitimation of a global status-quo.     

NARST: a lived history

In this Forum, we construct a history of the National Association for Research in Science Education (NARST) through the analysis of documents and through the personal perspectives of individuals. The history of NARST is inseparable from the biography of the individuals through whose lives it was produced and reproduced. The history of NARST is a living history that both shapes and was shaped by the biographies of its members.

Predictor variables of written picture naming in the deaf

Studies conducted in recent years on oral andwritten language production show that the ageat which words are learned is the main variablethat influences lexical access in both hearingpeople and people who have suffered brainlesions. No studies have been done with deafpeople and, since they use sign language inaddition to oral language, differencesregarding hearing people might be found intheir lexical organization. The aim of thisstudy was to test which variables determine thelexical production of deaf people. For thispurpose, 40 deaf people between the ages of 13and 58 years were asked to write individuallythe names of 100 pictures. The regressionanalyses performed on a total of 4000 responsesshow that the main predictor variable ofperformance was also age of acquisition. It isconcluded that the organization of the lexicalsystem in deaf people is similar to that of hearing people, although the phonologicalrepresentations of deaf people may be moreinaccurate.     

Employers’ skill preferences across Europe: between cognitive and non-cognitive skills

This article analyses online job advertisements to identify skills that are demanded in selected low- and medium-skilled occupations. We explore data from the publicly administered cross-European EURES job search portal and quantify the different cognitive and non-cognitive skills requested by employers in small European economies. While we find that the service sector demands non-cognitive skills more than other types of occupation, the skill-mix demanded is very diverse across countries, implying that other domestic factors shape how demand is formulated. Our work shows that online portals can become a useful source for studying employers’ demand at the micro-level to inform employment, education and training policies.     

Bridging memory-based collaborative filtering and text retrieval

When speaking of information retrieval, we often mean text retrieval. But there exist many other forms of information retrieval applications. A typical example is collaborative filtering that suggests interesting items to a user by taking into account other users’ preferences or tastes. Due to the uniqueness of the problem, it has been modeled and studied differently in the past, mainly drawing from the preference prediction and machine learning view point. A few attempts have yet been made to bring back collaborative filtering to information (text) retrieval modeling and subsequently new interesting collaborative filtering techniques have been thus derived. In this paper, we show that from the algorithmic view point, there is an even closer relationship between collaborative filtering and text retrieval. Specifically, major collaborative filtering algorithms, such as the memory-based, essentially calculate the dot product between the user vector (as the query vector in text retrieval) and the item rating vector (as the document vector in text retrieval). Thus, if we properly structure user preference data and employ the target user’s ratings as query input, major text retrieval algorithms and systems can be directly used without any modification. In this regard, we propose a unified formulation under a common notational framework for memory-based collaborative filtering, and a technique to use any text retrieval weighting function with collaborative filtering preference data. Besides confirming the rationale of the framework, our preliminary experimental results have also demonstrated the effectiveness of the approach in using text retrieval models and systems to perform item ranking tasks in collaborative filtering.     

The Librarian's Role in Linking Patients to Their Personal Health Data and Contextual Information

The objective of this project was to make an institution's patients aware of a new patient portal with contextual links to MedlinePlus. Through partnerships with information technology personnel and LSU Health Shreveport clinics, the Health Sciences Library created and distributed promotional and educational materials and instructed patients on how to use MyChart and access reliable consumer health information via MedlinePlus Connect. Although most patients were not interested in coming to the library for demonstrations, many of them expressed interest in using MyChart. The contextual information in MedlinePlus Connect worked well for most topics. The institutional team leader for MyChart expressed gratitude for librarian involvement.     

Validating chemical and structural changes in painting materials by principal component analysis of spectroscopic data using internal mineral standards

This work shows the capability of principal component analysis (PCA) to detect molecular, chemical and mineralogical changes in historic painting materials subjected to a thermal ageing test (< 250 °C). To simulate the heat-induced alterations an ageing accelerated process was performed on two sets of samples containing two mineral phases (hydroxyapatite and quartz) and two organic compounds (collagen and albumin). The chosen minerals behaved as internal standards during the tests since they are stable and chemically inert at the tested temperatures. Raman microscopy (RM) was applied to characterise one set of samples made of bone, containing ca. 70% hydroxyapatite and 30% collagen. Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy was used to study the other set of samples made of four different quartz/albumin mixtures with quartz contents of 30%, 50%, 70% and 90% (w/w). The aim was to identify the ideal proportion of internal standard to be validated by ATR-FTIR and PCA, determined to be 70%. PCA analyses detected changes in the molecular structures of the organic components while the internal mineral standard remained stable. Moreover, the internal standard IR/Raman bands were constant during the tests and confirmed that the results of PCA analyses were independent of instrumental and technical factors, as well as sample collecting and handling. This demonstrates the potential benefits of our approach to study historical painting materials, which have suffered any type of heat-induced alteration.     

An Eye-Tracking Study of Learning From Science Text With Concrete and Abstract Illustrations

This study investigated the online process of reading and the offline learning from an illustrated science text. The authors examined the effects of using a concrete or abstract picture to illustrate a text and adopted eye-tracking methodology to trace text and picture processing. They randomly assigned 59 eleventh-grade students to 3 reading conditions: (a) text only; (b) text with a concrete illustration; and (c) text with an abstract illustration in a pretest, immediate, and delayed posttest design. Results showed that the text illustrated by either the concrete or the abstract picture led to better learning than did the text alone. Eye-fixation data revealed that the abstract illustration promoted more efficient processing of the text. Analyses of the gaze shifts between the 2 types of external representation indicated that the readers of the text with the abstract illustration made a greater effort to integrate verbal and pictorial information. Furthermore, relations between online and offline measures emerged.     

Epigenetic Vestiges of Early Developmental Adversity: Childhood Stress Exposure and DNA Methylation in Adolescence

Fifteen‐year‐old adolescents (N = 109) in a longitudinal study of child development were recruited to examine differences in DNA methylation in relation to parent reports of adversity during the adolescents’ infancy and preschool periods. Microarray technology applied to 28,000 cytosine–guanine dinucleotide sites within DNA derived from buccal epithelial cells showed differential methylation among adolescents whose parents reported high levels of stress during their children’s early lives. Maternal stressors in infancy and paternal stressors in the preschool years were most strongly predictive of differential methylation, and the patterning of such epigenetic marks varied by children’s gender. To the authors’ knowledge, this is the first report of prospective associations between adversities in early childhood and the epigenetic conformation of adolescents’ genomic DNA.
