Mothers' use of cognitive state verbs in picture-book reading and the development of children's understanding of mind: a longitudinal study

Mothers read stories to their children (N=41) aged between 3.3 years and 5.11 years old, and children then completed two false-belief tasks. One year later, mothers read a story to 37 of those children who were also given four tasks to assess their advanced understanding of mental states. Mothers' early use of cognitive verbs in picture-book reading correlated with their children's later understanding of mental states. Some pragmatic aspects of maternal input correlated with children's later outcomes. Two different factors in mothers' cognitive discourse were identified, suggesting a zone of proximal development in children's understanding of mental states.

Unveiling the Colours of Cellulose Nitrate Black and White Film-based Negatives in Colonial Photography

ABSTRACT

Aiming at contributing to the preservation of black and white (B&W) film-based negatives held by Portuguese archives, four photographic collections from the first half of the twentieth century were selected for study. During the macro assessment of the collections the preservation condition and hues found in photographic negatives from the Elmano Cunha e Costa (ECC) were noticed, distinguishing this collection from the remaining ones. Additional attention was given considering that the ECC collection was formed in a colonial context in the 1930s, while the others were formed on the Portugal mainland. The ECC collection results from an ethnographic survey of Angolan tribes recorded with B&W film-based negatives. In this collection, sets of negatives with pink, lemon yellow, greenish, orange brownish, and red brownish hues were found. To identify the origin of such hues, the image layer was analysed by microscale energy-dispersive X-ray fluorescence (μ EDXRF) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX). Additionally, to assess the base decay and its effect on the formation of hues, the plastic supports were characterized by Fourier transform infrared microscopy (μ FTIR). To complement the assessment of the film-base decay, pH was measured by using combined microelectrodes. The identification of mercury, iodine, chromium, and iron by μ EDXRF allowed correlation of the hues found in the negatives with chemical corrective treatments performed to improve the image quality. SEM-EDX confirmed those results and proved that the elements found were in the photographic emulsion layer. The results obtained are relevant since the hues identified may now be used as markers to indicate the technical work performed on colonial photography. Additionally, the visual and molecular assessment of the negatives’ supports (good to fair condition) allow proposing that the original storage conditions may have had a beneficial contribution to their present condition.     

Insights into user engagement on social media. Case study of a higher education institution

ABSTRACT

The interactions of users in social networks have been analyzed in the literature as sources of information on their ability to generate engagement among stakeholders in higher education institutes, which make more tactical than strategic use of social networks. This study helps identify which variables generate greater participation in Instagram users, providing strategic proposals for digital marketing. From the codification of all the publications published by a university in a social network site during the period of one year, a comparative analysis was carried out through a multivariate model. The results provide important and timely implications for both universities and higher education professionals. Our findings suggest that higher education marketing specialists should develop stronger and more consistent communication strategies to establish more valuable relationships with stakeholders. The administrators of the social networks of higher education institutions can find patterns in those publications that generate a greater participation in this study.

Coping with Complexity and Instability in the UK Vocational Training System1

Vocational training systems that take the needs of the word of work seriously and maintain strong and dynamic connections with it are faced to growing complexity and instability. Some countries try to cope with this through creating new mediation mechanisms between the systems of training and work that allow higher level complexity while maintaining appropriate social control over the linkages between these systems. The training policy of the United Kingdom offers an interesting example for this. The key message of this article is that increasing complexity and high level instability may seriously impede the engagement of employers for training and human resource development but reducing it have to be made in a cautious way, so that it does not harm the achievement of the strategic goals of making training more demand-led, making it more responsive to the changing skills needs of companies and letting employers have a decisive role in determining the content of training and the way it is delivered. The skills policy of the United Kingdom is used as an example to illustrate the growing social complexity that characterise modern social systems, including vocational training, and one specific way of devising public policies based on new innovative forms of steering and regulating that enhance coping with complexity and instability.     

Educational decentralization: a review of popular discourse on Chinese–English bilingual education

Educational decentralization is a worldwide phenomenon, which takes different forms and leads to different outcomes in different socio-economic contexts. Taking Chinese–English bilingual education in Mainland China as an exemplar, this study examines how the decentralization of education has worked in China in the past two decades, and what consequences decentralization has brought about in the country. The analysis reveals that decentralization has created a favourable overall socio-economic and political context for bilingual education to develop, from a local endeavour into a nation-wide undertaking. The analysis also reveals that decentralization has allowed the diversified operation of bilingual programmes at the regional level. However, there has been a visible inconsistency and incoherence between the theoretical underpinnings of the programmes and the practice in schools and classrooms. Such an inconsistency and incoherence may have resulted from a newly reconfigured relation between the central government and local governments, as well as a lack of human or intellectual resources at the regional level, leading to some unintended educational and socio-political outcomes.     

Specific Learning Disabilities and the Portuguese Educational System

Although the Portuguese educational system advocates the accommodation of all students in regular schools, it has not adopted a coherent discourse that would contribute to meeting effectively the needs of students with specific learning disabilities (SLD). As such, the successive reorganizations of special education have resulted in uninformed decisions that have caused the education of students with SLD in Portugal to be, in many instances, detrimental to their academic and social growth. We describe the reality of SLD in Portugal, considering four main topics: (1) the establishment of the SLD concept, (2) the birth of a Portuguese definition of SLD, (3) the context of educational policy, and (4) the provision for students with SLD.
