Authors: Granato Daniel , Margraf Tiago , Brotzakis Ioannis , Capuano Edoardo , van Ruth Saskia M. 
Published: December 2014

AbstractThe objectives of this study were to characterize organic, biodynamic, and conventional purple grape juices (n = 31) produced in Europe based on instrumental taste profile, antioxidant activity, and some chemical markers and to propose a multivariate statistical model to analyze their quality and try to classify the samples from the 3 different crop systems. Results were subjected to ANOVA, correlation, and regression analysis, principal component analysis (PCA), hierarchical cluster analysis (HCA), soft independent modeling of class analogy (SIMCA), and partial least‐squares discriminant analysis (PLSDA). No statistical significant differences (P > 0.05) were observed among juices from the 3 crop systems. Using PCA and HCA, no clear separation among crop systems was observed, corroborating the ANOVA data. However, PCA showed that the producing region highly affects the chemical composition, electronic tongue parameters, and bioactivity of grape juices. In this sense, when organic and biodynamic were grouped as “nonconventional” juices, SIMCA model was able to discriminate 12 out of 13 organic/biodynamic juices and 17 out of 18 conventional juices, presenting an efficiency of 93.5%, while 11 out of 13 non‐conventional and 100% conventional grape juices were correctly classified using PLSDA. The use of electronic tongue and the determination of antioxidant properties and major phenolic compounds have shown to be a quick and accurate analytical approach to assess the quality of grape juices.

Published: December 2014

SummarySome isolates of the Bacillus subtilis/amyloliquefaciens species are known for their plant protective activity against fungal phytopathogens. It is notably due to their genetic potential to form an impressive array of antibiotics including non‐ribosomal lipopeptides (LPs). In the work presented here, we wanted to gain further insights into the relative role of these LPs in the global antifungal activity of B. subtilis/amyloliquefaciens. To that end, a comparative study was conducted involving multiple strains that were tested against four different phytopathogens. We combined various approaches to further exemplify that secretion of those LPs is a crucial trait in direct pathogen ward off and this can actually be generalized to all members of these species. Our data illustrate that for each LP family, the fungitoxic activity varies in function of the target species and that the production of iturins and fengycins is modulated by the presence of pathogens. Our data on the relative involvement of these LPs in the biocontrol activity and modulation of their production are discussed in the context of natural conditions in the rhizosphere.

AbstractAimTo assess patient satisfaction with the rheumatology telemedicine service provided to a rural town in northern Australia.MethodsA prospective, questionnaire‐based exploratory study of patients seen at the Mount Isa (rural town) rheumatology telemedicine clinics during 2012 was undertaken. Control groups included patients travelling over 3 h to be seen face‐to‐face in Townsville (tertiary referral centre), and patients seen at the infrequent face‐to‐face clinic in Mount Isa. A 5‐point Likert scale was used to explore themes of communication, confidentiality, physical examination, rapport, medication safety and access.ResultsThis study evaluated 107 rheumatology outpatients (49 telemedicine, 46 face‐to‐face Townsville, 12 face‐to‐face Mount Isa). Patients seen in Mount Isa travelled a median of < 10 km for either the telemedicine or local face‐to‐face appointments. The patients attending the Townsville face‐to‐face clinic travelled a median of 354 km. New patients comprised 14% of consultations. Satisfaction with themes related to quality‐of‐care was high with over 90% selecting ‘agree’ or ‘strongly agree’ to these questions. Comparing models of care, there were no statistically significant differences in the rates of those selecting ‘strongly agree’ across questions, apart from a single question related to rapport which favored the Mount Isa face‐to‐face model (P = 0.018). When asked whether they would rather travel to Townsville than participate in a telemedicine consultation, 63% of patients selected ‘disagree’ (17%) or ‘strongly disagree’ (46%).ConclusionsThese results suggest that patients are satisfied with a rheumatology telemedicine service, and may prefer this to extensive travelling. Evaluation in other settings is recommended before generalizing this finding.

AbstractAimTo detect subclinical peripheral arthritis and disease activity in axial seronegative spondyloarthritis (SpA) patients using bone scintigraphy.MethodsSeronegative SpA patients with an established diagnosis and no clinically evident arthritis at the time of the study were included. After excluding symptomatic cases, 20 patients were recruited; 18 with ankylosing spondylitis (AS) and another two with psoriatic arthritis (PsA). Conventional bone scintigraphy was performed to detect the distribution of increased uptake, blood vascular pool (vascularity) and activity.ResultsThe peripheral joints in all the patients were asymptomatic with no signs of arthritis on clinical examination. Disease activity was higher in those with hypervascularity and activity (75%) detected by scintigraphy. Scintigraphic activity of the sacroiliac joints was found in 10 patients (50%) with a mean sacroiliac joint index of 2.4 ± 0.6. Subclinical involvement of the hips, knees, shoulders, ankles, small joints of the hands, ankles and sternoclavicular joints, as well as the small joints of the feet were detected with descending frequencies (25%, 25%, 20%, 20%, 15%, 10% and 10%, respectively). Dorsal spine increased uptake was found in 35% and hypervascularity of the skull in two cases. Avascular necrosis of the hip was present in one case with hypovascularity.ConclusionThe spectrum of joint involvement in seronegative SpAs should not be limited to sacroiliitis. Bone scintigraphy provides a cost‐effective method for detecting the extent of involvement in this group of autoimmune systemic diseases (axial SpA) without clinical evidence of peripheral arthritis.

AbstractAimTo determine the prevalence of joint hypermobility (JH) among young Kuwaiti adults.MethodsThis was a cross‐sectional study of 390 randomly selected healthy undergraduate university students, aged 18–29 years from the Health Sciences Centre, Kuwait University, Safat, Kuwait. Beighton score at four peripheral sites bilaterally (knees, elbows, thumbs and fifth fingers) and forward flexion of the trunk were used to evaluate joint hypermobility. Any student who met four out of the nine criteria was considered hypermobile. Joint pain was documented in all subjects through personal interview.ResultsA total of 390 subjects (male : female ratio 1.0 : 0.9) were assessed. Of those, 87 (22.3%) were found to have JH: 60 (29.4%) males and 27 (14.5%) females, showing a significantly higher male predominance (P < 0.001). Beighton score was inversely correlated with age (ρ = −0.15, P = 0.003). A higher incidence of finger signs was noted in comparison to elbow‐knee hyperextension and hands‐to‐floor. Knee joint, back, neck and shoulder pains, in descending order, were the commonest type of joint complaints, although not statistically significant (P > 0.05) in subjects with and without joint hypermobility. It was also observed that the left side, at all the sites, was slightly more hypermobile in comparison to the right side in hypermobile subjects.ConclusionsThe prevalence of joint hypermobility is not uncommon among young Kuwaiti adults, and was comparable to the data published in other Asian‐Pacific regions. General practitioners should therefore be familiar with the condition and its clinical associations, while assessing musculoskeletal complaints.
Cultural discernment as an ethics framework: An Indigenous Fijian approach
Authors: Meo‐Sewabu Litea 
Published: December 2014

AbstractThe praxis of an Indigenous Fijian researcher who is both an insider/outsider offers some valuable lessons for ethnographic work. This paper introduces ‘cultural discernment’ as a concept used to ensure that the research process is culturally ethical within the research setting. An insider will always require a sense of cultural discernment, recognising that actions taken have implications that are critical and remain with the researcher for life. The paper contextualises the concept of cultural discernment in relation to Fijian epistemology. Although there are risks within any research project with regard to ethics processes and the conduct of research, this paper will illustrate how Western paradigms associated with ‘expert knowledge’ and the ‘lay knowledges’ of an Indigenous population group produce competing understandings about ethical practice. The paper draws on a doctoral research project exploring the cultural conceptualisation of health and well‐being, conducted in Fiji and New Zealand. The research process and steps carried out in this study ensured those actions were culturally appropriate and ethically sound from an Indigenous Fijian perspective.
Changing market culture in the Pacific: Assembling a conceptual framework from diverse knowledge and experiences

Published: December 2014

AbstractAddressing the multiple dimensions of gender inequality requires commitments by policy‐makers, practitioners and scholars to transformative practices. One challenge is to assemble a coherent conceptual framework from diverse knowledges and experiences. In this paper, we present a framework that emerged from our involvement in changing market culture in the Pacific, which we name a radical empowerment of women approach. We draw on detailed narratives from women market vendors and women‐led new initiatives in marketplaces to explain this approach. We argue that the primary focus of recently developed projects for marketplaces in the Pacific is technical and infrastructural, which is insufficient for addressing gendered political and economic causes of poor market management and oppressive conditions for women vendors. By exploring the complex array of motives and effects of the desire to transform or improve marketplaces in the Pacific, we caution against simplistic technical or infrastructural solutions. This paper also introduces the practice of working as a cooperative, hybrid research collaboration. The knowledges and analyses that we bring to this issue demonstrate that substantive analysis generated from diverse and shifting ‘locations’ and roles, but underpinned by a shared vision of, and commitment to, gender justice, can provide distinctive policy and research insights.
Practical critique: Bridging the gap between critical and practice‐oriented REDD+ research communities

AbstractReducing Emissions from Deforestation and Forest Degradation (REDD+) is an ambitious global programme oriented towards improving forest carbon management. It aims to attract new sources of ‘green’ capital to fund emissions reductions from avoided deforestation and sustainable forest management. REDD+ is transforming forest conservation, as a diverse array of new stakeholders become involved. Not surprisingly, REDD+ has proved divisive, as critics concern themselves with issues of power, justice, and commodification, while practice‐oriented researchers tackle similar issues from different perspectives, focusing on benefit sharing, safeguards, additionality, measuring and verification. In this paper we explore the different roles of critical and practical research, and argue that there is a need for greater sharing of knowledge across current divides. We draw on our own experiences of conducting a research project on REDD+ in Indonesia that involved critical and practice‐oriented researchers. We argue that critical research disconnected from practical matters can have perverse outcomes for practitioners who are ultimately working towards similar goals; while uncritical practice‐oriented research has the potential to lead to a dilution of core values of environmental justice and conservation. In contrast, forms of practical critique provide ways of researching REDD+ that have practical value while maintaining critical insights.
‘Governed freedom’ in Oceania: AusAID, subjectivation and the practice of critique in studies of governmentality
Authors: Hodge Paul 
Published: December 2014

AbstractDrawing predominantly on the work of Butler, Rose and Walters, this paper examines the governing rationalities and technologies that characterise one particular site of aid relations. Focusing on key policy documents, economic surveys and performance reports, the paper traces the fashioning of particular subjectivities as constitutive of AusAID's development objectives and the function of problematisation and responsibilisation as central to these practices of subjectivation. While I argue the freedom on offer as part of AusAID's development objectives is a highly governed one – where the ‘free’ economic‐rational subject adopts certain ‘civilised sensibilities’ (Rose, 1999: 78), I show how this process of subjectivation encompasses both ‘a power exerted on a subject’ and ‘a power assumed by the subject’ (Butler, 1997: 11). What becomes apparent through this analysis is the productive and tenuous characteristics of these practices of subject formation. This paper also foregrounds the practice of critique itself, and the very act of research; concepts adopted and explanations made, as far from innocent in their performativity in enacting some worlds and not others.
Evolution of angiosperm seed disperser mutualisms: the timing of origins and their consequences for coevolutionary interactions between angiosperms and frugivores
Authors: Eriksson Ove 
Published: December 2014

ABSTRACTThe origins of interactions between angiosperms and fruit‐eating seed dispersers have attracted much attention following a seminal paper on this topic by Tiffney (1984). This review synthesizes evidence pertaining to key events during the evolution of angiosperm–frugivore interactions and suggests some implications of this evidence for interpretations of angiosperm–frugivore coevolution. The most important conclusions are: (i) the diversification of angiosperm seed size and fleshy fruits commenced around 80 million years ago (Mya). The diversity of seed sizes, fruit sizes and fruit types peaked in the Eocene around 55 to 50 Mya. During this first phase of the interaction, angiosperms and animals evolving frugivory expanded into niche space not previously utilized by these groups, as frugivores and previously not existing fruit traits appeared. From the Eocene until the present, angiosperm–frugivore interactions have occurred within a broad frame of existing niche space, as defined by fruit traits and frugivory, motivating a separation of the angiosperm–frugivore interactions into two phases, before and after the peak in the early Eocene. (ii) The extinct multituberculates were probably the most important frugivores during the early radiation phase of angiosperm seeds and fleshy fruits. Primates and rodents are likely to have been important in the latter part of this first phase. (iii) Flying frugivores, birds and bats, evolved during the second phase, mainly during the Oligocene and Miocene, thus exploiting an existing diversity of fleshy fruits. (iv) A drastic climate shift around the Eocene–Oligocene boundary (around 34 Mya) resulted in more semi‐open woodland vegetation, creating patchily occurring food resources for frugivores. This promoted evolution of a ‘flying frugivore niche’ exploited by birds and bats. In particular, passerines became a dominant frugivore group worldwide. (v) Fleshy fruits evolved at numerous occasions in many angiosperm families, and many of the originations of fleshy fruits occurred well after the peak in the early Eocene. (vi) During periods associated with environmental change altering coevolutionary networks and opening of niche space, reciprocal coevolution may result in strong directional selection formative for both fruit and frugivore evolution. Further evidence is needed to test this hypothesis. Based on the abundance of plant lineages with various forms of fleshy fruits, and the diversity of frugivores, it is suggested that periods of rapid coevolution in angiosperms and frugivores occurred numerous times during the 80 million years of angiosperm–frugivore evolution.
Evolutionary perspectives on human height variation
Authors: Stulp Gert , Barrett Louise 
Published: December 2014

ABSTRACTHuman height is a highly variable trait, both within and between populations, has a high heritability, and influences the manner in which people behave and are treated in society. Although we know much about human height, this information has rarely been brought together in a comprehensive, systematic fashion. Here, we present a synthetic review of the literature on human height from an explicit evolutionary perspective, addressing its phylogenetic history, development, and environmental and genetic influences on growth and stature. In addition to presenting evidence to suggest the past action of natural selection on human height, we also assess the evidence that natural and sexual selection continues to act on height in contemporary populations. Although there is clear evidence to suggest that selection acts on height, mainly through life‐history processes but perhaps also directly, it is also apparent that methodological factors reduce the confidence with which such inferences can be drawn, and there remain surprising gaps in our knowledge. The inability to draw firm conclusions about the adaptiveness of such a highly visible and easily measured trait suggests we should show an appropriate degree of caution when dealing with other human traits in evolutionary perspective.
Children infer affiliative and status relations from watching others imitate
Authors: Over Harriet , Carpenter Malinda 
Published: December 2014

AbstractWe investigated whether young children are able to infer affiliative relations and relative status from observing others' imitative interactions. Children watched videos showing one individual imitating another and were asked about the relationship between those individuals. Experiment 1 showed that 5‐year‐olds assume that individuals imitate people they like. Experiment 2 showed that children of the same age assume that an individual who imitates is relatively lower in status. Thus, although there are many advantages to imitating others, there may also be reputational costs. Younger children, 4‐year‐olds, did not reliably make either inference. Taken together, these experiments demonstrate that imitation conveys valuable information about third party relationships and that, at least by the age of 5, children are able to use this information in order to infer who is allied with whom and who is dominant over whom. In doing so, they add a new dimension to our understanding of the role of imitation in human social life.
Inexperienced newborn chicks use geometry to spontaneously reorient to an artificial social partner

Published: December 2014

AbstractA fundamental process underlying navigation behaviour, shown to occur in every species tested, uses geometric properties of the environment for location memory and orientation. Here we employ a new method to ask whether this basic geometric orientation ability is innately predisposed in the brain or depends on specific experiences navigating in a geometrically rich environment. Using the newborn domestic chick as a model system, we present a working memory task testing reorientation towards a filial imprinting object under rigorous controlled rearing conditions. In the absence of any previous exposure to a geometrically rich environment, newly hatched chicks spontaneously recovered their bearings by making use of distances and directional relations to reorient themselves to an artificial social partner. These findings provide evidence for an innate capacity to navigate by the geometric structure of the environment.
Constraints on statistical computations at 10 months of age: the use of phonological features
Authors: Gonzalez‐Gomez Nayeli , Nazzi Thierry 
Published: December 2014

AbstractRecently, several studies have argued that infants capitalize on the statistical properties of natural languages to acquire the linguistic structure of their native language, but the kinds of constraints which apply to statistical computations remain largely unknown. Here we explored French‐learning infants' perceptual preference for labial‐coronal (LC) words over coronal‐labial words (CL) words (e.g. preferringbatovertab) to determine whether this phonotactic preference is based on the acquisition of the statistical properties of the input based on a single phonological feature (i.e. place of articulation), multiple features (i.e. place and manner of articulation), or individual consonant pairs. Results from four experiments revealed that infants had a labial‐coronal bias for nasal sequences (Experiment 1) and for all plosive sequences (Experiments 2 and 4) but a coronal‐labial bias for all fricative sequences (Experiments 3 and 4), independently of the frequencies of individual consonant pairs. These results establish for the first time that constellations of multiple phonological features, defining broad consonant classes, constrain the early acquisition of phonotactic regularities of the native language.
