Scientific evidence by fluorescence spectrometry for safflower red on ancient Japanese textiles stored in the Shosoin Treasure House repository

Shosoin textiles, handed down from the eighth century in Nara, Japan, have entranced many people with their beautiful colors made from natural dyes. Dye analysis of the Shosoin textiles, including the red carpet laid inside the workshop hall at the Todaiji Temple in Nara, used for the inauguration of the statue of the Great Buddha in the temple in 752 AD; a red undergarment and a gown with a tie-dyed design worn by craftsmen in the Todaiji Temple; and embroidered shoes belonging to Empress Komyo (701–760 AD), were conducted by excitation–emission matrix fluorescence spectrometry equipped with a fiber optics probe. Comparison of the spectra to references identified safflower red (Carthamus tinctorius L.) in the red or orange areas on these original textiles. The spectrometry of the gown and the shoes offered the identification not only of safflower red but also of amur cork tree. This study finds these examples to be the oldest scientifically confirmed presence of safflower red on historic textiles at present.     

An Overview of Systematic-Functional Grammar

The key notions in Halliday’s Systematic Grammar and Functional Grammar are first summarized, and then contrasted with Chomsky’s Transformational-Generative Grammar. Results show that Systematic-Functional Grammar could be viewed as complementa ry to Transformational-Generative Grammar. They combine to reveal the whole picture of language.     

All in a knot of one another's labours: self-determination,network organising and learning

This essay is about how to learn to organise to tackle the intractable and most difficult problems of organisations and societies. It opens with a discussion of the nature of such problems, which are the spur for Revans' action learning and the focus of some recent thinking on leadership. Action learning works on the basis of peer relationships and self-determination lends itself naturally to attempts to organise in networks rather than in hierarchies. Taking cancer care as an example of an intractable problem, the centre point of the essay is a case study of an NHS Cancer Network which shows the complex dependencies and connections of this way of working. Although the recent history of organising has been summed up as a trajectory ‘from hierarchies to networks’, I argue that our capabilities with the intractable and wicked problems are limited by our dependence upon hierarchical models of organising and also by management practices that are best suited to ‘tame’ problems and a management education tradition that produces ‘subalterns’ rather than self-determining actors. These points are made via an excursion through three philosophies of freedom: post-colonialism, anarchism and Quakerism. These ideas reveal the cultural legacies to be overcome in the quest to learn how to organise with free actors. The triple practices of action learning, distributed leadership and network organising are offered as being part of the solution.     

Motherhood as Contested Ideological Terrain: Essentialist and Queer Discourses of Motherhood at Play in Female–female Co-mothers' Talk

Framed by relational dialectics theory (Baxter), this investigation considered the meaning(s) of motherhood in female–female co-motherhood. Analysis identified two competing discourses: (1) discourse of essential motherhood (DEM) and (2) discourse of queer motherhood (DQM). Speakers' invocation of the DEM reinscribes the mainstream US cultural discourse that children can have only one authentic (i.e., biological) mother, whereas invocation of the DQM denaturalizes the DEM's presumptions of authentic motherhood as biological, interrupts monomaternalism, destabilizes the patriarch, and troubles the equation of biological with moral motherhood. Whereas interpenetrations of the DEM and DQM were typically sites of adversarial discursive struggle, in a few instances, the DEM and DQM rose above their antagonistic relationship, combining to create new meanings of motherhood.     

The first steps for adapting an artificial intelligence emotion expression recognition software for emotional management in the educational context

To test the suitability of an automatic system for emotional management in the classroom following the control-value theory of achievement emotions (CVT) framework, the performance of an emotional expression recognition software of our creation is evaluated in an online synchronous context. Sixty students from the Faculty of Education at the University of Alicante participated in 16 educational activities recording close-ups of their faces and completing the AEQ emotional self-report, as well as detailed reports from the subsequent review of their videos. In addition, they completed the VCQ-36 test to measure their volitional competencies and relate their influence on their emotional response. The results indicate a high coherence between the emotional expressions detected by the automatic system and the detailed emotional self-reports, but insufficient precision to meet the CVT requirements. On the other hand, both the AEQ test results and the emotion expression recognition software suggest students' preference for participative activities as opposed to passive ones. Meanwhile, statistical analysis results indicate that volitional competencies seem to influence the emotional response of students in the educational context, although the AI system does not show sufficient sensitivity in this field. Implications and limitations of this study for future work are discussed.

Practitioner notes

What is already known about this topic

• Student motivation and involvement in the learning process are highly related to appropriate emotional regulation, which can be associated with particular educational activities, strategies and methodologies.
• Deep learning technology based on convolutional neural networks feeds automatic systems focused on facial expression recognition from image analysis.

What this paper adds

• There is high coherence between the emotional expressions detected by the AI system and the students' emotional self-reports, but the AI system provides just emotional valences, insufficient to meet the CVT framework.
• Both emotional self-reports and the emotion recognition software suggest students' preference for active educational activities as opposed to passive ones.
• Volitional competencies seem to influence the emotional response of students in the educational context.

Implications for practice and/or policy

• It is possible to use automatic systems to effectively monitor the emotional response of students in the learning process.
• Only if sensitivity improved, a real-time, easy-to-interpret emotional expression recognition software interface could be implemented to assist teachers with the emotional management of their classes within the CVT framework, maximizing their motivation and engagement.
