Organic-walled microfossils of the mid-Neoproterozoic Alinya Formation, Officer Basin, Australia
Authors: Riedman Leigh Anne , Porter Susannah 
Published: September 2016

AbstractEstimates of Precambrian eukaryotic diversity and disparity indicate broad trends of increase in the Mesoproterozoic Era, leading to a peak and then rapid decline by ca. 750 Ma. The organic-walled microfossil assemblage presented here is representative of that mid-Neoproterozoic height of eukaryotic species richness. Organic-rich shales and siltstones of the mid-Neoproterozoic upper Alinya Formation, eastern Officer Basin, Australia, preserve an abundant and diverse assemblage of organic-walled microfossils deposited in a low-latitude, shallow marine setting. Use of scanning electron microscopy (SEM) revealed an unexpected level of morphological detail not visible in transmitted light microscopy. This led to the recognition of new species as well as establishment of degradational sequences, which aid in fossil recognition. In total, 26 taxa are described here; these include 21 previously named forms, four newly described species (Caelatimurus foveolatus, Culcitulisphaera revelata,Karenagare alinyaensis, andMorgensternia officerensis), and one new combination (Vidalopalla verrucata).
ON REALS WITH -BOUNDED COMPLEXITY AND COMPRESSIVE POWER
Authors: HERBERT IAN 
Published: September 2016

AbstractThe (prefix-free) Kolmogorov complexity of a finite binary string is the length of the shortest description of the string. This gives rise to some ‘standard’ lowness notions for reals: A isK-trivial if its initial segments have the lowest possible complexity and A is low forKif using A as an oracle does not decrease the complexity of strings by more than a constant factor. We weaken these notions by requiring the defining inequalities to hold only up to all${\rm{\Delta }}_2^0$orders, and call the new notions${\rm{\Delta }}_2^0$-bounded K-trivialand${\rm{\Delta }}_2^0$-bounded low for K. Several of the ‘nice’ properties ofK-triviality are lost with this weakening. For instance, the new weaker definitions both give uncountable set of reals. In this paper we show that the weaker definitions are no longer equivalent, and that the${\rm{\Delta }}_2^0$-boundedK-trivials are cofinal in the Turing degrees. We then compare them to other previously studied weakenings, namelyinfinitely-often K-trivialityandweak lowness for K(in each, the defining inequality must hold up to a constant, but only for infinitely many inputs). We show that${\rm{\Delta }}_2^0$-boundedK-trivial implies infinitely-oftenK-trivial, but no implication holds between${\rm{\Delta }}_2^0$-bounded low forKand weakly low forK.
REDUCTS OF STRUCTURES AND MAXIMAL-CLOSED PERMUTATION GROUPS
Authors: BODIRSKY MANUEL , MACPHERSON DUGALD 
Published: September 2016

AbstractAnswering a question of Junker and Ziegler, we construct a countable first order structure which is not ω-categorical, but does not have any proper nontrivial reducts, in either of two senses (model-theoretic, and group-theoretic). We also construct a strongly minimal set which is not ω-categorical but has no proper nontrivial reducts in the model-theoretic sense.
DEFINABILITY OF SATISFACTION IN OUTER MODELS
Authors: FRIEDMAN SY-DAVID , HONZIK RADEK 
Published: September 2016

AbstractLet M be a transitive model of ZFC. We say that a transitive model of ZFC, N, is an outer model of M if M ⊆ N and ORD ∩ M = ORD ∩ N. The outer model theory of M is the collection of all formulas with parameters from M which hold in all outer models of M (which exist in a universe in which M is countable; this is independent of the choice of such a universe). Satisfaction defined with respect to outer models can be seen as a useful strengthening of first-order logic. Starting from an inaccessible cardinal κ, we show that it is consistent to have a transitive model M of ZFC of size κ in which the outer model theory is lightface definable, and moreover M satisfies V = HOD. The proof combines the infinitary logic L∞,ω, Barwise’s results on admissible sets, and a new forcing iteration of length strictly less than κ+ which manipulates the continuum function on certain regular cardinals below κ. In the appendix, we review some unpublished results of Mack Stanley which are directly related to our topic.
Notes from Libya
Authors: Bennett Paul 
Published: September 2016

Abstract‘Notes from Libya’ is a new regular feature of Libyan Studies and follows the reports of the Society's Head of Mission. These reports were previously concerned with the organisation of fieldwork and administrative matters connected to obtaining permissions, visas, and so on, and were recorded in the minutes of the Council meetings. However, they have recently taken on a new form, outlining the alarming developments in Libya, largely focusing on its heritage but also on the political and economic situation, which impacts on the management of Libya's ancient monuments and artefacts. The importance and historical interest of these reports now, however, merit a wider audience and a more formal record, so these accounts are now published in Libyan Studies.
Let the people sing? Irish rebel songs, sectarianism, and Scotland's Offensive Behaviour Act
Authors: Millar Stephen R. 
Published: September 2016

AbstractIrish rebel songs afford Scotland's Irish diaspora a means to assert, experience and perform their alterity free from the complexities of the Irish language. Yet this benign intent can be offset by how the music is perceived by elements of Scotland's majority Protestant population. The Scottish Government's Offensive Behaviour Act (2012) has been used to prosecute those singing Irish rebel songs and there is continuing debate as to how this alleged offence should be dealt with. This article explores the social function and cultural perception of Irish rebel songs in the west coast of Scotland, examining what qualities lead to a song being perceived as ‘sectarian’, by focusing on song lyrics, performance context and extra-musical discourse. The article explores the practice of lyrical ‘add-ins’ that inflect the meaning of key songs, and argues that the sectarianism of a song resides, at least in part, in the perception of the listener.
Language ideology and kadongo kamu flow
Authors: Pier David 
Published: September 2016

AbstractKadongo kamu is a Ugandan guitar-based genre recognisable by its dense storytelling lyrics in Luganda language. This article offers a close analysis of kadongo kamu musical style, focusing on the interface between speech rhythm and musical rhythm. The style's poetic-musical ‘flow’ to be structurally analysed is interpreted with reference to a historically evolved language ideology which construes Luganda to be exceptionally ‘rich’ and ‘deep’. I show how specific musical techniques are used to foreground aspects of Luganda that speakers prize as elegant and learned. This musical artistry enhances listeners’ impressions of the proverb-rich ‘deep Luganda’ poetry for which kadongo kamu singers are famous.
The mobilising of the German 1848 protest song tradition in the context of international twentieth-century folk revivals
Authors: Robb David 
Published: September 2016

AbstractThe rediscovery of democratic traditions of folk song in Germany after the Second World War was not just the counter-reaction of singers and academics to the misuse of German folk song by the Nazis. Such a shift to a more ‘progressive’ interpretation and promotion of folk tradition at that time was not distinct to Germany and had already taken place in other parts of the Western world. After firstly examining the relationship between folk song and national ideologies in the nineteenth century, this article will focus on the democratic ideological basis on which the 1848 revolutionary song tradition was reconstructed after the Third Reich. It will look at how the New Social Movements of West Germany and the folk scene of the GDR functioned in providing channels of transmission for this, and how in this process a collective cultural memory was created whereby lost songs – such as those of the 1848 Revolution – could be awakened from extinction. These processes will be illustrated by textual and musical adaptations of key 1848 songs such as ‘Badisches Wiegenlied’ (Baden Lullaby), ‘Das Blutgericht’ (The Blood Court) and ‘Trotz alledem’ (For all that) within the context of the West German folk movement and its counterpart in the GDR.
Behind the magical mystery door: history, mythology and the aura of Abbey Road Studios
Authors: Bennett Samantha 
Published: September 2016

AbstractIn rock historiography, Abbey Road Studios is depicted as the rock canon's ultimate recording house; home to the Beatles, Pink Floyd and a generation of classic rock album production. In recent years, the studio has struggled to maintain itself as an operational recording house, yet effectively exploits its past to secure its future. This article considers issues of heritage, pilgrimage and tourism before elucidating brand ‘Abbey Road’ as a conflation of geographical location, zebra crossing, graffiti wall, recording house and aura. In separating the tangible aspects of Abbey Road's heritage – the zebra crossing, graffiti wall and the Beatles Abbey Road album – out from its intangibles – its ‘magic’, legacy and studio ‘vibe’ – Abbey Road's studio aura is exposed as a commodity in its own right.
TREATMENT SWITCHING: STATISTICAL AND DECISION-MAKING CHALLENGES AND APPROACHES
Authors: Latimer Nicholas R. , Henshall Chris , Siebert Uwe , Bell Helen 
Published: September 2016

Objectives: Treatment switching refers to the situation in a randomized controlled trial where patients switch from their randomly assigned treatment onto an alternative. Often, switching is from the control group onto the experimental treatment. In this instance, a standard intention-to-treat analysis does not identify the true comparative effectiveness of the treatments under investigation. We aim to describe statistical methods for adjusting for treatment switching in a comprehensible way for nonstatisticians, and to summarize views on these methods expressed by stakeholders at the 2014 Adelaide International Workshop on Treatment Switching in Clinical Trials.Methods: We describe three statistical methods used to adjust for treatment switching: marginal structural models, two-stage adjustment, and rank preserving structural failure time models. We draw upon discussion heard at the Adelaide International Workshop to explore the views of stakeholders on the acceptability of these methods.Results: Stakeholders noted that adjustment methods are based on assumptions, the validity of which may often be questionable. There was disagreement on the acceptability of adjustment methods, but consensus that when these are used, they should be justified rigorously. The utility of adjustment methods depends upon the decision being made and the processes used by the decision-maker.Conclusions: Treatment switching makes estimating the true comparative effect of a new treatment challenging. However, many decision-makers have reservations with adjustment methods. These, and how they affect the utility of adjustment methods, require further exploration. Further technical work is required to develop adjustment methods to meet real world needs, to enhance their acceptability to decision-makers.
Ferries in the Firthlands: Communications, Society and Culture along a Northern Scottish Rural Coast, c. 1600 to c. 1809
Authors: WORTHINGTON DAVID 
Published: September 2016

Abstract:This article identifies the social and cultural history of the early modern tidal water ferry, its skippers and passengers, by way of evidence from a northern Scottish rural coast. Evidence from the region's ‘firthlands’ reveals an amphibious communications network which transformed gradually prior to the early nineteenth century. The article argues that the defining local topography of coastal adjacency both influenced, and was influenced by, the people who lived their lives within and around the littoral. A system of short range communications over and between the estuaries and firths is highlighted from a Coastal History perspective, leading to the examination of a ‘pluriactive’ microhistorical space, linking south-east Sutherland, the eastern edges of Easter Ross and the Black Isle and the Nairnshire seaboard. The article thereby opens up possibilities for comparison with other peoples, places and periods, in which being ‘alongshore’ was integral to rural community construction, coalescence, dynamism and friction.
Effects of photoperiod on population performance and sexually dimorphic responses in two major arbovirus mosquito vectors, Aedes albopictus and Aedes aegypti (Diptera: Culicidae)

Published: September 2016

AbstractThe Asian tiger mosquito,Aedes albopictus(Skuse) and the yellow fever mosquito,Aedes aegypti(Linnaeus) are medically important species that vector several arboviruses. Globally, populations of both species experience (and are sensitive to) photoperiodic variations. The present study aims to test if photoperiod regimes affect the population performance ofAe. albopictusandAe. aegypti. Since mosquitoes have sex-specific strategies to maximize fitness, we also tested the hypothesis thatAe. albopictusandAe. aegyptiwould exhibit differences in the male and female response (sexually dimorphic response) to various photoperiod treatments. We reared cohorts of first instar larvae to adulthood in three photoperiod treatments: short day (10 h light), control (12 h light) and long day (14 h light). We measured and compared survival to adulthood, population growth, development time of males and females, and wing length across treatments. Although we detected no effects of photoperiod on the population performance of both species, we found evidence of a sexual dimorphic response to photoperiod inAe. albopictus, but not inAe. aegypti, withAe. albopictusfemales being more sensitive to variations in photoperiod. The observed differences between sexes ofAe. albopictusare consistent with sex-specific developmental constraints. The absence of a sexually dimorphic response to photoperiod inAe. aegyptican be attributed to different strategies evolved in this species to prepare for unfavourable conditions associated with shorter day length. We discuss the ecological and medical implications of our findings.

AbstractBackground/Objectives:Phenylketonuria (PKU) is an autosomal recessive disease caused by deficient activity of phenylalanine hydroxylase. A low phenylalanine (Phe) diet is used to treat PKU. The diet is very restrictive, and dietary adherence tends to decrease as patients get older. Methods to improve dietary adherence and blood Phe control are continuously under investigation.Subjects/Methods:A new formula Phe-neutral amino acid (PheLNAA) has been tested in this study with the purpose of improving the compliance and lowering blood phenylalanine. The formula has been tested for nitrogen balance, and it is nutritionally complete. It is fortified with more nutritional additives that can be deficient in the PKU diet, such as B12, Biotin, DHA, Lutein and increased levels of large neutral amino acids to help lower blood Phe. The new formula has been tested on 12 patients with a loading test of 4 weeks.Results:Fifty-eight percent of patients had a significant decline in blood Phe concentration from baseline throughout the study. The PheLNAA was well tolerated with excellent compliance and without illnesses during the study.Conclusions:In conclusion, the new formula is suitable for life-long treatment of PKU, and it offers the PKU clinic a new choice for treatment.
Neurons in the primate dorsal striatum signal the uncertainty of object–reward associations
Authors: White J. Kael , Monosov Ilya E. 
Published: September 2016

AbstractTo learn, obtain reward and survive, humans and other animals must monitor, approach and act on objects that are associated with variable or unknown rewards. However, the neuronal mechanisms that mediate behaviours aimed at uncertain objects are poorly understood. Here we demonstrate that a set of neurons in an internal-capsule bordering regions of the primate dorsal striatum, within the putamen and caudate nucleus, signal the uncertainty of object–reward associations. Their uncertainty responses depend on the presence of objects associated with reward uncertainty and evolve rapidly as monkeys learn novel object–reward associations. Therefore, beyond its established role in mediating actions aimed at known or certain rewards, the dorsal striatum also participates in behaviours aimed at reward-uncertain objects.

AbstractReorientation of cucumber seedlings induces re-localization of CsPIN1 auxin efflux carriers in endodermal cells of the transition zone between hypocotyl and roots. This study examined whether the re-localization of CsPIN1 was due to the graviresponse. Immunohistochemical analysis indicated that, when cucumber seedlings were grown entirely under microgravity conditions in space, CsPIN1 in endodermal cells was mainly localized to the cell side parallel to the minor axis of the elliptic cross-section of the transition zone. However, when cucumber seeds were germinated in microgravity for 24 h and then exposed to 1g centrifugation in a direction crosswise to the seedling axis for 2 h in space, CsPIN1 was re-localized to the bottom of endodermal cells of the transition zone. These results reveal that the localization of CsPIN1 in endodermal cells changes in response to gravity. Furthermore, our results suggest that the endodermal cell layer becomes a canal by which auxin is laterally transported from the upper to the lower flank in response to gravity. The graviresponse-regulated re-localization of CsPIN1 could be responsible for the decrease in auxin level, and thus for the suppression of peg formation, on the upper side of the transition zone in horizontally placed seedlings of cucumber.
Generation of self-clusters of galectin-1 in the farnesyl-bound form

Published: September 2016

AbstractRas protein is involved in a signal transduction cascade in cell growth, and cluster formation of H-Ras and human galectin-1 (Gal-1) complex is considered to be crucial to achieve its physiological roles. It is considered that the complex is formed through interactions between Gal-1 and the farnesyl group (farnesyl-dependent model), post-translationally modified to the C-terminal Cys, of H-Ras. We investigated the role of farnesyl-bound Gal-1 in the cluster formation by analyzing the structure and properties of Gal-1 bound to farnesyl thiosalicylic acid (FTS), a competitive inhibitor of the binding of H-Ras to Gal-1. Gal-1 exhibited self-cluster formation upon interaction with FTS, and small- and large-size clusters were formed depending on FTS concentration. The galactoside-binding pocket of Gal-1 in the FTS-bound form was found to play an important role in small-size cluster formation. Large-size clusters were likely formed by the interaction among the hydrophobic sites of Gal-1 in the FTS-bound form. The present results indicate that Gal-1 in the FTS-bound form has the ability to form self-clusters as well as intrinsic lectin activity. Relevance of the self-clustering of FTS-bound Gal-1 to the cluster formation of the H-Ras–Gal-1complex was discussed by taking account of the farnesyl-dependent model and another (Raf-dependent) model.

Published: September 2016

AbstractCholestasis is a clinically significant symptom and widely associated with liver diseases, however, there are very few effective therapies for cholestasis. Danning tablet (DNT, a Chinese patent medicine preparation) has been clinically used to treat human liver and gallbladder diseases for more than 20 years in China. However, which ingredients of DNT contributed to this beneficial effect and their mechanistic underpinnings have been largely unknown. In the present study, we discovered that DNT not only demonstrated greater benefits for cholecystitis patients after cholecystectomy surgery in clinic but also showed protective effect against alpha-naphthylisothiocyanate (ANIT)-induced cholestasis model in rodent. Curcumin, one major compound derived from DNT, exerted the protective effect against cholestasis through farnesoid X receptor (FXR), which has been focused as potential therapeutic targets for treating cholestasis. The underlying mechanism of curcumin against cholestasis was restoring bile acid homeostasis and antagonizing inflammatory responses in a FXR-dependent manner and in turn contributed to overall cholestasis attenuation. Collectively, curcumin can be served as a potential treatment option for liver injury with cholestasis.

Published: September 2016

AbstractAnimals foraging in their natural environments need to be proficient at recognizing and responding to changes in food targets that affect accessibility or pose a risk. Wild bearded capuchin monkeys (Sapajus libidinosus) use stone tools to access a variety of nut species, including otherwise inaccessible foods. This study tests whether wild capuchins from Serra da Capivara National Park in Brazil adjust their tool selection when processing cashew (Anacardium spp.) nuts. During the ripening process of cashew nuts, the amount of caustic defensive substance in the nut mesocarp decreases. We conducted field experiments to test whether capuchins adapt their stone hammer selection to changing properties of the target nut, using stones of different weights and two maturation stages of cashew nuts. The results show that although fresh nuts are easier to crack, capuchin monkeys used larger stone tools to open them, which may help the monkeys avoid contact with the caustic hazard in fresh nuts. We demonstrate that capuchin monkeys are actively able to distinguish between the maturation stages within one nut species, and to adapt their foraging behaviour accordingly.
