Expressivist theories of law focus not only on what legal arrangements do but also what they communicate. The expressivist view has gained special currency in the context of religious establishment. Even when governmental involvement with religion is not coercive or does not materially violate anyone’s rights, it may nevertheless be undesirable by virtue of expressing a preference for a certain religion or a privileged status for certain religious groups over others. The existing literature, however, lacks an equivalent expressivist analysis of the related but distinct domain of free exercise of religion. What is expressed when a religious individual or group is granted special relief from the legal requirements that would otherwise apply to them? I argue that just like religious establishments, religious exemptions not only implicate rights and material interests but also have important expressive dimensions that both help account for their value and impose limits on their desirability.

Micromelalopha troglodyta (Graeser) is an important pest of poplar in China, and glutathione S-transferase (GST) is an important detoxifying enzyme in M. troglodyta. In this paper, three full-length GST genes from M. troglodyta were cloned and identified. These GST genes all belonged to the epsilon class (MtGSTe1, MtGSTe2, and MtGSTe3). Furthermore, the expression of these three MtGSTe genes in different tissues, including midguts and fat bodies, and the MtGSTe expression in association with different concentrations of tannic acid, including 0.001, 0.01, 0.1, 1, and 10 mg ml−1, were analysed in detail. The results showed that the expression levels of MtGSTe1, MtGSTe2, and MtGSTe3 were all the highest in the fourth instar larvae; the expression levels of MtGSTe1 and MtGSTe3 were the highest in fat bodies, while the expression level of MtGSTe2 was the highest in midguts. Furthermore, the expression of MtGSTe mRNA was induced by tannic acid in M. troglodyta. These studies were helpful to clarify the interaction between plant secondary substances and herbivorous insects at a deep level and provided a theoretical foundation for controlling M. troglodyta.

During the Civil War, many Americans were prepared for censorship if free speech undermined preserving the Union. Journalists were unable to obtain timely accurate information on the military campaigns either for fear of helping the enemy or depressing morale at home. Self-censorship was far more important than official suppression of free speech, as spontaneous popular pressure curtailed freedom of expression at the beginning of the war and later on the army performed a similar function. For Federals, commitment to preserving the Union required treating Confederates as ubiquitous seditious conspirators. Combatting this internal enemy, in turn, especially in the Border States, required extensive suppression of free speech. Later in the conflict and right across the Union, the critical and urgent need to fill the ranks led to official censorship of any words that might discourage volunteering, and this conflicted with freedom of religion as well as speech and the press.

Intuitively, a speaker who uses slurs to refer to people is doing something morally objectionable even if no one is measurably affected by their speech. Perhaps they are only talking to themselves, or they are speaking with bigots who are already as vicious as they can be. This paper distinguishes between slurring as an expressive act and slurring as the act of causing a psychological effect. It then develops an expression-focused ethical account in order to explain the intuition that slurring involves an effect-independent moral wrong. The core idea is that the act of expressing a morally defective attitude is itself pro tanto morally objectionable. Unlike theories that focus only on problematic effects, this view is able to shift the moral burden of proof away from victims of slurring acts and onto speakers. It also offers moral guidance with respect to metalinguistic and pedagogical utterances of slurs.

In this article, I discuss two approaches to the phenomenon of gesture, constituted by the existential dimension of embodiment, intersubjectivity, affectivity, and language: while Martin Heidegger states that human bodily movement as a whole should be understood as gesture in contrast to the spatial movement of things, Vilém Flusser integrates under this notion a multitude of human practices and activities that common sense hesitates to call gestures. The dilemma of the phenomenology of gesture consists in this tension between the plural concreteness of gestural appearances and the irrepressible temptation to identify a unitary layer that would allow them to hold together.

Darwin's book on expressions of emotion was one of the first publications to include photographs (Darwin, The expression of the emotions in Man and animals, 1872). The inclusion of expression photographs meant that readers could form their own opinions and could, like Darwin, survey others for their interpretations. As such, the images provided an evidence base and an ‘open source’. Since Darwin, increases in the representativeness and realism of emotional expressions have come from the use of composite images, colour, multiple views and dynamic displays. Research on understanding emotional expressions has been aided by the use of computer graphics to interpolate parametrically between different expressions and to extrapolate exaggerations. This review tracks the developments in how emotions are illustrated and studied and considers where to go next.

The sequence of musical development is revisited. The origins of the underlying and evolving theory are considered, along with organisation and classification of the data of children’s compositions. The cumulative and recursive nature of the spiral is re-emphasised, and the dynamic relationship between the left and right side is clarified. The essential qualitative nature of the study is asserted and some possibilities for the future are considered, along with a two-dimensional model for curriculum and student evaluation based on spiral-related outcomes and the musical activities that promote and sustain them.

June Boyce-Tillman and Keith Swanwick’s article on musical development is the second most widely cited paper in the history of the British Journal of Music Education. It appears in many discussions of musical development. A selection of the diverse domains where the paper is cited includes: instrumental teaching, Special Education Needs, primary school teaching, the development of learning for professional musicians, secondary school teaching, musicians’ skill development, adult music teaching and jazz improvisation. However, the background to this work, which was conceived for June Boyce-Tillman’s PhD thesis, is not always so well known. This article presents a research interview with June Boyce-Tillman conducted in August 2017. It explores her musical background and music education experiences, and seeks to enable further discussion of the characteristics which were described in the spiral model. The interview focuses on the concepts of Materials, vernacular, and musical Values, in particular, and the implications of these modes of understanding for classroom practices, including curriculum design.

The study was undertaken to examine the relative abundance (RA) of the major developmental important candidate genes in different grades of immature oocytes (A-grade, B-grade, C-grade and D-grade) and various stages of in vitro-produced embryos (2-cell, 4-cell, 8–16-cell, morula, and blastocyst) of buffalo using RT-qPCR. Results showed that the RA of GLUT1, CX43, HSP70.1 and GDF9 was significantly higher (P < 0.05) in the A-grade of oocytes than the C-grade and D-grade but did not differ significantly from the B-grade of oocytes. Similarly, RA of BMP15 and Survivin were significantly higher (P < 0.05) in A-grade than the other grades of oocytes, however, poly(A) polymerase expression was not significantly different (P > 0.05) among the immature oocytes. The expression of GLUT1 was significantly higher (P < 0.05) in the blastocysts, but the expression of CX43 (P < 0.05; P > 0.05), HSP70.1 (P < 0.05; P > 0.05) and GDF9 (P > 0.05) was higher at the 2-cell stage than the other stages of embryos. Interestingly, the expression levels of poly(A) polymerase (P < 0.05), BMP15 (P < 0.05; P > 0.05) and Survivin (P > 0.05) were higher at the 8–16-cell stage than the other stages of embryos. It is concluded that A-grade of immature oocytes has shown more mRNA abundance for the major developmental important genes; therefore A-grade oocytes may be considered as the most developmentally competent and suitable for handmade cloning research in buffalo.
