In 2015 the Naprstek Museum, in cooperation with the National Library of the Czech Republic, carried out a conservation survey of two rare folios from the Gulshan Album of the Mughal emperor Jahāngīr which form part of the Naprstek Museum’s Indian collection. During the survey an unknown signature by the painter Āqā Rezā was discovered in the border of one of them. The new finding was the impetus for this study, looking at the folio in more detail. In addition to the introductory part, which looks at the form and function of illustrated albums in the Mughal Empire, the study describes in detail both a miniature on one side of the folio and the calligraphy and border with human figures on the other side, and explains the relationship between them.

AbstractThe information to be obtained from thorough life-history studies is an extremely useful tool, perhaps especially so when ecology is being emphasized, as it is to-day, by the life-table and other mathematical approaches to the study of population processes. This information is desired by workers in many fields of entomology – by the biological and chemical control experts, the biomathematicians, the theorists and even the taxonomists. However, much of the knowledge that these workers require, for instance the fine distinctions of behaviour and environment, has been overlooked in most life-history studies, and I strongly suspect that one of the weaknesses of studies of this nature has been the failure to analyse the mode of living of an insect (or, in the case of Lepidoptera, of the immature forms) in relation to the anatomy on one hand and environmental circumstances on the other. To look for these relationships, I believe that one requires (a) the ability and perseverance to perceive detail as minute as that required for a taxonomic study, and (b) a considerable knowledge of the taxonomic detail that is to be obtained from basic morphological studies. Therefore, in this paper, attention is drawn to pertinent structural characters of lepidopterous larvae and their probable connection with the behaviour and microhabitats of the larvae, in the hope that some guidance may be offered to future students of life-histories, at least in Lepidoptera.

STM is one of the most promising techniques available for visualizing the fine details of biomolecular structure. It has been used to map the surface topography of inorganic materials in atomic dimensions, and thus has the resolving power not only to determine the conformation of small molecules but to distinguish site-specific features within a molecule. That level of detail is of critical importance in understanding the relationship between form and function in biological systems. The size, shape, and accessibility of molecular structures can be determined much more accurately by STM than by electron microscopy since no staining, shadowing or labeling with heavy metals is required, and there is no exposure to damaging radiation by electrons. Crystallography and most other physical techniques do not give information about individual molecules.We have obtained striking images of DNA and RNA, using calf thymus DNA and two synthetic polynucleotides, poly(dG-me5dC)·poly(dG-me5dC) and poly(rA)·poly(rU).

ABSTRACTMolluscs biomineralize structures that vary in composition, form, and function, prompting questions about the genetic mechanisms responsible for their production and the evolution of these mechanisms. Chitons (Mollusca, Polyplacophora) are a promising system for studies of biomineralization because they build a range of calcified structures including shell plates and spine- or scale-like sclerites. Chitons also harden the calcified teeth of their rasp-like radula with a coat of iron (as magnetite). Here we present the genome of the West Indian fuzzy chiton Acanthopleura granulata, the first from any aculiferan mollusc. The A. granulata genome contains homologs of many biomineralization genes identified previously in conchiferan molluscs. We expected chitons to lack genes previously identified from pathways conchiferans use to make biominerals like calcite and nacre because chitons do not use these materials in their shells. Surprisingly, the A. granulata genome has homologs of many of these genes, suggesting that the ancestral mollusc had a more diverse biomineralization toolkit than expected. The A. granulata genome has features that may be specialized for iron biomineralization, including a higher proportion of genes regulated directly by iron than other molluscs. A. granulata also produces two isoforms of soma-like ferritin: one is regulated by iron and similar in sequence to the soma-like ferritins of other molluscs, and the other is constitutively translated and is not found in other molluscs. The A. granulata genome is a resource for future studies of molluscan evolution and biomineralization.SIGNIFICANCE STATEMENTChitons are molluscs that make shell plates, spine- or scale-like sclerites, and iron-coated teeth. Currently, all molluscs with sequenced genomes lie within one major clade (Conchifera). Sequencing the genome of a representative from the other major clade (Aculifera) helps us learn about the origins and evolution of molluscan traits. The genome of the West Indian Fuzzy Chiton, Acanthopleura granulata, reveals chitons have homologs of many genes other molluscs use to make shells, suggesting all molluscs share some shell-making pathways. The genome of A. granulata has more genes that may be regulated directly by iron than other molluscs, and chitons produce a unique isoform of a major iron-transport protein (ferritin), suggesting that chitons have genomic specializations that contribute to their production of iron-coated teeth.

The Relationship

In the realm of muscle atrophy research, many studies address minute details of molecular function but few examine the effects of atrophy in terms of mobility, strength, endurance, and performance of activities of daily living. The relationship between impairment and functional limitation is the focus of this research review. A wide array of studies constitute this area of inquiry, including investigations as diverse and widely disparate as molecular chemistry and space travel and populations as different as rats, healthy young men, and elderly women. Thirty-four studies were selected based on their fit with the Enabling-Disabling Model. Three paradigms of atrophy and function emerged. Adaptation reflects the plastic nature of muscle when placed under certain conditions, ranging from disuse to high-resistance exercise. Injury/loss describes damage to muscle tissue from ischemia, medications, or reloading or reperfusion trauma. Also in this category is the loss of muscle that is seen with aging. Integrity relates to the muscle’s tendency to protect itself and maintain structural adjacencies and cellular proportions. Based on the 3 muscle research paradigms, the relationship of muscle atrophy to function is portrayed as a bidirectional interaction wherein form and function have an influence on each other by way of physical changes, including those of adaptation, injury/loss, or integrity. A conceptual model is constructed to reflect this relationship.

This paper analyses constraints on inflectional syncretism and inflectional allomorphy using frequency information. Syncretism arises where one form is associated with more than one function, whereas inflectional allomorphy occurs where there is more than one inflectional class, and a single function is associated with two or more forms. If high frequency is associated with more differentiation on both sides, we expect, on the one hand, that a frequent function will have a high number of forms and, on the other, that a frequent form will have a high number of functions. Our study focuses on Russian nominals, in particular nouns, which exhibit both syncretism and inflectional allomorphy. We find that there is a relationship between frequency and differentiation, but that it is not exceptionless, and that the exceptions can be understood in terms of the use of referrals as default rules.

This article discusses a recent art project created by the Wiradjuri and Kamilaroi artist Jonathon Jones, which was commissioned to commemorate the opening of the revitalized Hyde Park Barracks in Sydney in early 2020. Jones’ work involves a dramatic installation of red and white crushed stones laid throughout the grounds of the barracks, merging the image of the emu footprint with that of the English broad convict arrow to ‘consider Australia’s layered history and contemporary cultural relations’. This work was accompanied by a ‘specially-curated programme’ of performances, workshops, storytelling and Artist Talks. Together, these elements were designed to unpack how certain ‘stories determine the ways we came together as a nation’. As one of the speakers of the Artist Talk’s programme, I had a unique opportunity to experiment with what colleagues and I have been calling ‘Creative histories’ in reference to the way some artists and historians are choosing to communicate their research about the past in ways that experiment with form and function and push disciplinary or generic boundaries. This article reflects upon how these two distinct creative history projects – one visual art, the other performative – renegotiate the complex and contested pasts of the Hyde Park Barracks. I suggest that both examples speak to the role of memory and creativity in shaping cultural responses to Australia’s colonial past, while Jones' programme illustrates how Indigenous artists and academics are making a profound intervention into contemporary understandings of how history is ‘done’ in Australia.

The Relationship

This paper deals with the complex interaction between form and function in the verb morphosyntax of four Indo-European languages (French, Italian, Ancient Greek and Sanskrit). Beyond the difference in form, auxiliation patterns in French and Italian, and verb inflections in Ancient Greek and Sanskrit correlate, thanks to the agreement for number and person, to the expression of the relationship with the Subject. The different auxiliation patterns (sum and habeo) and the different inflections (middle and active) correlate to different properties of the Subject. In particular, these forms depend on the syntactic opposition between middle and non-middle. The ways of this dependency are regulated and systematic, although they appear fuzzy and chaotic, not only if the four languages are compared to each other, but also if different morphosyntactic combinations, inside the same language, are concerned.

The study of language contact has been traditionally carried out from a structural perspective (synchronic or diachronic), from a sociolinguistic perspective and/or from a rather psychological perspective, centered on the linguistic and communicative competence of the multilingual individual. However, a great number of linguistic and sociolinguistic topics that appear in language contact situations may be productively tackled from a pragmatic viewpoint. This pragmatic perspective takes into account linguistic use in communication contexts and raises, at a different level, questions that deal with the structures and the evolution of the codes in contact. The main aim of this presentation is the analysis of some of the specific problems that arise in given language contact situations from a pragmatic perspective, considering the adaptation processes of the speakers, their particular interactive strategies and the social meaning generated. Understanding pragmatics in its original sense, i.e. as the study of the relationship between linguistic signs and speakers (users of certain resources), these phenomena should be understood as the result of speakers’ adaptation to changing sociocultural circumstances. This adaptation creates a new distribution of the verbal resources (or linguistic economy) of the community and, consequently, modifies its varieties as far as form and function are concerned.

ABSTRACTIn this paper I wish to respond to the article published in ET94 by Saraceni while at the same time providing some clarifications concerning the concept of English as a Lingua Franca (henceforth ELF). In his article Saraceni raises three main questions (and a number of related debatable comments which I will quickly deal with in my final remarks) regarding: 1) the nature of ELF and its speakers, 2) the relationship between ELF and the World Englishes (henceforth WE) paradigm, and 3) the distinction between form and function. I will address each of these questions, and in so doing consider a number of notions concerning the ELF research field.
