Published: July 2017

Purpose:

The aim of the current study was to replicate findings in adults indicating that higher sensitivity to stressful events is predictive of both onset and persistence of psychopathological symptoms in a sample of adolescents and young adults. In addition, we tested the hypothesis that sensitivity to mild stressors in particular is predictive of the developmental course of psychopathology.

Methods:

We analyzed experience sampling and questionnaire data collected at baseline and one-year follow-up of 445 adolescent and young adult twins and non-twin siblings (age range: 15–34). Linear multilevel regression was used for the replication analyses. To test if affective sensitivity to mild stressors in particular was associated with follow-up symptoms, we used a categorical approach adding variables on affective sensitivity to mild, moderate and severe daily stressors to the model.

Results:

Linear analyses showed that emotional stress reactivity was not associated with onset (ß = .02; P = .56) or persistence (ß = -.01; P = .78) of symptoms. There was a significant effect of baseline symptom score (ß = .53; P < .001) and average negative affect (NA: ß = .19; P < .001) on follow-up symptoms. Using the categorical approach, we found that affective sensitivity to mild (ß = .25; P < .001), but not moderate (ß = -.03; P = .65) or severe (ß = -.06; P = .42), stressors was associated with symptom persistence one year later.

Discussion:

We were unable to replicate previous findings relating stress sensitivity linearly to symptom onset or persistence in a younger sample. Whereas sensitivity to more severe stressors may reflect adaptive coping, high sensitivity to the mildest of daily stressors may indicate an increased risk for psychopathology.

Published: July 2017

Cognitive behavioural therapy (CBT) is beneficial in depression. Symptom scores can be translated into Clinical Global Impression (CGI) scale scores to indicate clinical relevance. We aimed to assess the clinical relevance of findings of randomised controlled trials (RCTs) of CBT in depression. We identified RCTs of CBT that used the Hamilton Rating Scale for Depression (HAMD). HAMD scores were translated into Clinical Global Impression – Change scale (CGI-I) scores to measure clinical relevance. One hundred and seventy datasets from 82 studies were included. The mean percentage HAMD change for treatment arms was 53.66%, and 29.81% for control arms, a statistically significant difference. Combined active therapies showed the biggest improvement on CGI-I score, followed by CBT alone. All active treatments had better than expected HAMD percentage reduction and CGI-I scores. CBT has a clinically relevant effect in depression, with a notional CGI-I score of 2.2, indicating a significant clinical response. The non-specific or placebo effect of being in a psychotherapy trial was a 29% reduction of HAMD.
Anxiety and depression symptoms among sub-fertile women, women pregnant after infertility treatment, and naturally pregnant women
Authors: Salih Joelsson L. , Tydén T. , Wanggren K. , Georgakis M.K. , Stern J. , Berglund A. , Skalkidou A.
Published: July 2017

Background:

Infertility has been associated with psychological distress, but whether these symptoms persist after achieving pregnancy via assisted reproductive technology (ART) remains unclear. We compared the prevalence of anxiety and depressive symptoms between women seeking for infertility treatment and women who conceived after ART or naturally.

Methods:

Four hundred and sixty-eight sub-fertile non-pregnant women, 2972 naturally pregnant women and 143 women pregnant after ART completed a questionnaire in this cross-sectional study. The Anxiety subscale of the Hospital Anxiety and Depression Scale (HADS-A≥8) and Edinburgh Postnatal Depression Scale (EPDS≥12) were used for assessing anxiety and depressive symptoms, respectively. Multivariate Poisson regression models with robust variance were applied to explore associations with anxiety and depressive symptoms.

Results:

The prevalence of anxiety and depressive symptoms among sub-fertile, non-pregnant women (57.6% and 15.7%, respectively) were significantly higher compared to women pregnant after ART (21.1% and 8.5%, respectively) and naturally pregnant women (18.8% and 10.3%, respectively). History of psychiatric diagnosis was identified as an independent risk factor for both anxiety and depressive symptoms. The presence of at least one unhealthy lifestyle behavior (daily tobacco smoking, weekly alcohol consumption, BMI≥25, and regular physical exercise < 2 h/week) was also associated with anxiety (Prevalence Ratio, PR: 1.24; 95%CI: 1.09–1.40) and depressive symptoms (PR: 1.25; 95%CI: 1.04–1.49).

Conclusions:

Women pregnant after ART showed no difference in anxiety and depressive symptoms compared to naturally pregnant women. However, early psychological counseling and management of unhealthy lifestyle behaviors for sub-fertile women may be advisable, particularly for women with a previous history of psychiatric diagnosis.
Crafting a third space: Integrative strategies for implementing critical citizenship education in a standards-based classroom
Authors: Cho Hyunhee
Published: July 2017

In the transformative era of globalization, traditional conceptions of citizenship are challenged by a new idea of citizenship education in which students are empowered to get involved in civic actions designed to promote social justice. This single case study extends scholarship on critical citizenship education by illuminating the experience of a South Korean elementary teacher who effectively implemented the teaching of critical consciousness and social action skills in the standards-based social studies classroom by responding creatively to the mandated standards. The findings highlight three instructional strategies that the teacher created to deal with dilemmas recognized in the practice of critical citizenship education. Practical implications are provided to help teachers, teacher educators, and school leaders craft better opportunities for children to be engaged in critical citizens.
Comparison of patients diagnosed with “complex pain” and “somatoform pain”
Authors: Cour Peter la
Published: July 2017

Background and aim

Chronic pain conditions can be diagnosed and treated in both somatic and psychiatric settings. It is still a discussed and unanswered question whether the two groups of patients differ. The purpose of this short article is to inform further reflections concerning the classifications of somatoform pain and complex pain.

Method

Sociodemographic and questionnaire data concerning anxiety and depression, perceived injustice, well-being, and levels of psycho-physiological functioning were compared for patients diagnosed with complex pain (somatic diagnosis) at a pain clinic and somatoform pain (psychiatric diagnosis) at a Liaison-psychiatric clinic.

Results

Very little differences were found between patients with complex pain (N = 162) and somatoform conditions (N = 89). Both patient groups were seriously impaired both physically and mentally.

Conclusion

These comparisons lend support to the viewpoint of non-segregation of somatoform and complex pain.

Implications

Pain treatment might be better-managed in common multidisciplinary centers with specialists in both pain treatment and psychiatric aid.
Prehospital Emergency Medicine at the Beach: What Is the Effect of Fins and Rescue Tubes in Lifesaving and Cardiopulmonary Resuscitation After Rescue?
Authors: Abelairas-Gómez Cristian , Barcala-Furelos Roberto , Mecías-Calvo Marcos , Rey-Eiras Ezequiel , López-García Sergio , Costas-Veiga Javier , Bores-Cerezal Antonio , Palacios-Aguilar Jose
Published: July 2017

Objective

To analyze the influence of fins and rescue tube use in a water rescue, assessed by time and distance to salvage position, physiological parameters, and cardiopulmonary resuscitation (CPR).

Methods

Twenty professional lifeguards (10 men, 10 women) conducted 3 tests: a baseline test of 5 minutes of CPR and 2 water rescues, 1 without rescue equipment (NRE), and the other with fins and rescue tube (FRT). They also had to perform 5 minutes of CPR after each rescue. Time and distance of the rescues, physiological parameters (blood lactate concentration and heart rate), and quality of CPR were analyzed.

Results

CPR quality worsened by 26 to 28% ( P < .001) after rescue. However, there were no differences using FRT. The use of rescue equipment reduced the time (FRT: 216±57 seconds; NRE: 319±127 seconds; P < .001) and distance covered (FRT: 265±52 m; NRE: 326±41 m; P < .001). No differences were found in lactate levels between FRT and NRE just after the rescues, but there were some after 5 minutes of subsequent CPR (FRT: 10.7±2.2 mmol/L; NRE: 12.6±1.8 mmol/L; P < .001). Comparing women with men, we found significant differences in lactate concentrations only in FRT (women: 9.6±1.4 mmol/L; men: 8.1±1.2 mmol/L; P = .031).

Conclusions

The use of fins and rescue tube provides a comprehensive benefit in an aquatic emergency. However, FRT did not have any effect on the quality of the postrescue CPR.
Descriptive Epidemiology, Medical Evaluation, and Outcomes of Rock Climbing Injuries
Authors: McDonald James W. , Henrie A. Michael , Teramoto Masaru , Medina Edward , Willick Stuart E.
Published: July 2017

Objective

To gather epidemiologic data on injury type, treatment, and recovery from rock climbing injuries.

Methods

Design: retrospective cross-sectional study. Setting: web-based survey. Participants: rock climbers who sustained a climbing-related injury during the prior 24 months. Criteria for inclusion: aged ≥18 years; participation in rock climbing at least 4 times per year in the United States. Interventions: none. Main outcome measures: percentage of injured climbers seeking medical care, providers seen, subspecialty referral, development of chronic problems, factors affecting return to climbing, injuries by climbing type, body region, and injury type.

Results

Data were collected over a 60-day period using the Research Electronic Data Capture (REDCap) survey system. Seven hundred and eight surveys were collected from 553 male and 155 female climbers. Thirteen hundred ninety seven injuries were reported, and 975 injuries were suitable for analysis. The most common provider initially seen was a primary care provider. Subspecialty referral was commonly obtained. Injury patterns differed by climbing type. The percentage of respondents that returned to climbing before their injury was fully healed was 51.1%, and 44.9% of respondents developed chronic problems related to their climbing injury. Twenty-eight percent of respondents were unable to return to their previous level of climbing performance. Several factors were associated with delayed recovery from climbing injury.

Conclusions

A significant number of climbers sought healthcare after injury. A majority of climbers who sought treatment were referred to subspecialist providers. About one-half of climbers were symptomatic when they returned to climbing and developed chronic problems after injury. Factors associated with slower return to climbing included increasing age, smoking, fractures, and surgery.
Time and Environmental Law
Authors: Richardson Benjamin J.
Published: July 2017

Disciplined by industrial clock time, modern life distances people from nature's biorhythms such as its ecological, evolutionary, and climatic processes. The law is complicit in numerous ways. It compresses time through 'fast-track' legislation and accelerated resource exploitation. It suffers from temporal inertia, such as 'grandfathering' existing activities that limits the law's responsiveness to changing circumstances. Insouciance about past ecological damage, and neglect of its restoration, are equally serious temporal flaws: we cannot live sustainably while Earth remains degraded and unrepaired. Applying international and interdisciplinary perspectives on these issues, Time and Environmental Law explores how to align law with the ecological 'timescape' and enable humankind to 'tell nature's time'. Lending insight into environmental behaviour and impacts, this book pioneers a new understanding of environmental law for all societies, and makes recommendations for its reform. Minding nature, not the clock, requires regenerating Earth, adapting to its changes, and living more slowly.
Muhammad's Heirs
Authors: Brockopp Jonathan E.
Published: July 2017

Muslim scholars are a vital part of Islam, and are sometimes considered 'heirs to the prophets', continuing Muhammad's work of establishing Islam in the centuries after his death. But this was not always the case: indeed, Muslims survived the turmoil of their first century largely without the help of scholars. In this book, Jonathan Brockopp seeks to determine the nature of Muslim scholarly communities and to account for their emergence from the very beginning of the Muslim story until the mid-tenth century. By analysing coins, papyri and Arabic literary manuscripts from the ancient mosque-library of Kairouan, Tunisia, Brockopp offers a new interpretation of Muslim scholars' rise to positions of power and influence, serving as moral guides and the chief arbiters of Muslim tradition. This book will be of great benefit to scholars of comparative religion and advanced students in Middle Eastern history, Islamic Studies, Islamic Law and early Islamic literature.
The Matter of History
Authors: LeCain Timothy J.
Published: July 2017

New insights into the microbiome, epigenetics, and cognition are radically challenging our very idea of what it means to be 'human', while an explosion of neo-materialist thinking in the humanities has fostered a renewed appreciation of the formative powers of a dynamic material environment. The Matter of History brings these scientific and humanistic ideas together to develop a bold, new post-anthropocentric understanding of the past, one that reveals how powerful organisms and things help to create humans in all their dimensions, biological, social, and cultural. Timothy J. LeCain combines cutting-edge theory and detailed empirical analysis to explain the extraordinary late-nineteenth century convergence between the United States and Japan at the pivotal moment when both were emerging as global superpowers. Illustrating the power of a deeply material social and cultural history, The Matter of History argues that three powerful things - cattle, silkworms, and copper - helped to drive these previously diverse nations towards a global 'Great Convergence'.
Astral Sciences in Early Imperial China
Authors: Morgan Daniel Patrick
Published: July 2017

Challenging monolithic modern narratives about 'Chinese science', Daniel Patrick Morgan examines the astral sciences in China c.221 BCE–750 CE as a study in the disunities of scientific cultures and the narratives by which ancients and moderns alike have fought to instil them with a sense of unity. The book focuses on four unifying 'legends' recounted by contemporary subjects: the first two, redolent of antiquity, are the 'observing of signs' and 'granting of seasons' by ancient sage kings; and the other two, redolent of modernity, involve the pursuit of 'accuracy' and historical 'accumulation' to this end. Juxtaposing legend with the messy realities of practice, Morgan reveals how such narratives were told, imagined, and re-imagined in response to evolving tensions. He argues that, whether or not 'empiricism' and 'progress' are real, we must consider the real effects of such narratives as believed in and acted upon in the history of astronomy in China.
Disability and Community Living Policies
Authors: Rimmerman Arie
Published: July 2017

This book provides a comprehensive analysis of the roots of institutionalization, deinstitutionalization legislation and policies of the twentieth century, and twenty-first-century efforts to promote community living policies domestically and internationally, particularly through the role of the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD), a landmark treaty adopted on 13 December 2006. Rimmerman shows that deinstitutionalization and community living cannot be examined only in terms of the number of institutions closed but also through the substantial change in values, legislation, and policies supporting personalization, as well as the social participation of people with disabilities. The book includes a significant exploration of United States legislation and important Supreme Court decisions compared with European policies toward community living. Finally it discusses the importance of Articles 12 and 19 of the convention and demonstrates the case of Israel that has used the convention as a road map for proposing a new community living policy.
Reconstructing Alliterative Verse
Authors: Cornelius Ian
Published: July 2017

The poetry we call 'alliterative' is recorded in English from the seventh century until the sixteenth, and includes Caedmon's 'Hymn', Beowulf, Sir Gawain and the Green Knight, and Piers Plowman. These are some of the most admired works of medieval English literature, and also among the most enigmatic. The formal practice of alliterative poets exceeded the conceptual grasp of medieval literary theory; theorists are still playing catch-up today. This book explains the distinctive nature of alliterative meter, explores its differences from subsequent accentual-syllabic forms, and advances a reformed understanding of medieval English literary history. The startling formal variety of Piers Plowman and other Middle English alliterative poems comes into sharper focus when viewed in diachronic perspective: the meter was in transition; to understand it, we need to know where it came from and where it was headed at the moment it died out.
Hope and Christian Ethics
Authors: Elliot David
Published: July 2017

The theological virtue of hope has long been neglected in Christian ethics. However, as social, civic and global anxieties mount, the need to overcome despair has become urgent. This book proposes the theological virtue of hope as a promising source of rejuvenation. Theological hope sustains us from the sloth, presumption and despair that threaten amid injustice, tragedy and dying; it provides an ultimate meaning and transcendent purpose to our lives; and it rejoices and refreshes us 'on the way' with the prospect of eternal beatitude. Rather than degrading this life and world, hope ordains earthly goods to our eschatological end, forming us to pursue social justice with a resilience and vitality that transcend the cynicism and disillusionment so widespread at present. Drawing on Thomas Aquinas and virtue ethics, the book shows how the virtue of hope contributes to human happiness in this life and not just the next.
John Rawls: Reticent Socialist
Authors: Edmundson William A.
Published: July 2017

This book is the first detailed reconstruction of the late work of John Rawls, who was perhaps the most influential philosopher of the twentieth century. Rawls's 1971 treatise, A Theory of Justice, stimulated an outpouring of commentary on 'justice-as-fairness,' his conception of justice for an ideal, self-contained, modern political society. Most of that commentary took Rawls to be defending welfare-state capitalism as found in Western Europe and the United States. Far less attention has been given to Rawls's 2001 book, Justice as Fairness: A Restatement. In the Restatement, Rawls not only substantially reformulates the 'original position' argument for the two principles of justice-as-fairness but also repudiates capitalist regimes as possible embodiments. Edmundson further develops Rawls's non-ideal theory, which guides us when we find ourselves in a society that falls well short of justice.
Marking the Jews in Renaissance Italy
Authors: Cassen Flora
Published: July 2017

It is a little known fact that as early as the thirteenth century, Europe's political and religious powers tried to physically mark and distinguish the Jews from the rest of society. During the Renaissance, Italian Jews first had to wear a yellow round badge on their chest, and then later, a yellow beret. The discriminatory marks were a widespread phenomenon with serious consequences for Jewish communities and their relations with Christians. Beginning with a sartorial study - how the Jews were marked on their clothing and what these marks meant - the book offers an in-depth analysis of anti-Jewish discrimination across three Italian city-states: Milan, Genoa, and Piedmont. Moving beyond Italy, it also examines the place of Jews and Jewry law in the increasingly interconnected world of Early Modern European politics.
Nationwide survey on current management strategies of toddler’s fractures
Authors: Seguin Jade , Brody Daniel , Li Patricia
Published: July 2017

Background

Tibial fractures are common in children less than 3 years old. The traditional management involves immobilization in an above knee cast for both confirmed (positive x-ray) and presumed (normal x-ray) toddler’s fractures. This carries health care implications and causes unnecessary burden for patients and their families. There is a paucity of literature describing the ideal immobilization strategy for this injury.

Objectives

To determine: 1) the variation between Canadian emergency departments in management of toddler’s fractures; 2) the variation in management between confirmed and presumed toddler’s fractures; 3) the association between demographic variables and immobilization strategies.

Methods

This was an email survey of all members of the Pediatric Emergency Research Canada network. The survey consisted of 2 clinical vignettes followed by multiple-choice questions.

Results

Survey response rate was 73% (153/211). For confirmed toddler’s fractures, 39% of physicians chose to immobilize with above knee circumferential cast, 27% with below knee circumferential cast and 20% with below knee splint. For presumed toddler’s fractures, 44% of respondents chose to manage without casting, 22% with below knee splint and 14% with above knee circumferential cast. There was significant practice variation between Canadian pediatric emergency departments for both types of fractures and between the management of confirmed and presumed toddler’s fractures.

Conclusions

Our study is the first to identify nationwide variation in the management of toddler’s fractures. This variation highlights the need for future research to compare the different management strategies to determine families’ preferences and functional outcomes in children with these injuries.

Published: July 2017

OBJECTIVE

To evaluate antimicrobial utilization and prescription practices in a neonatal intensive care unit (NICU) after implementation of an antimicrobial stewardship program (ASP).

DESIGN

Quasi-experimental, interrupted time-series study.

SETTING

A 54-bed, level IV NICU in a regional academic and tertiary referral center.

PATIENTS AND PARTICIPANTS

All neonates prescribed antimicrobials from January 1, 2011, to June 30, 2016, were eligible for inclusion.

INTERVENTION

Implementation of a NICU-specific ASP beginning July 2012.

METHODS

We convened a multidisciplinary team and developed guidelines for common infections, with a focus on prescriber audit and feedback. We conducted an interrupted time-series analysis to evaluate the effects of our ASP. Our primary outcome measure was days of antibiotic therapy (DOT) per 1,000 patient days for all and for select antimicrobials. Secondary outcomes included provider-specific antimicrobial prescription events for suspected late-onset sepsis (blood or cerebrospinal fluid infection at >72 hours of life) and guideline compliance.

RESULTS

Antibiotic utilization decreased by 14.7 DOT per 1,000 patient days during the stewardship period, although this decrease was not statistically significant (P=.669). Use of ampicillin, the most commonly antimicrobial prescribed in our NICU, decreased significantly, declining by 22.5 DOT per 1,000 patient days (P=.037). Late-onset sepsis evaluation and prescription events per 100 NICU days of clinical service decreased significantly (P<.0001), with an average reduction of 2.65 evaluations per year per provider. Clinical guidelines were adhered to 98.75% of the time.

CONCLUSIONS

Implementation of a NICU-specific antimicrobial stewardship program is feasible and can improve antibiotic prescribing practices.

Ice velocity changes on Penny Ice Cap, Baffin Island, since the 1950s
Authors: SCHAFFER NICOLE , COPLAND LUKE , ZDANOWICZ CHRISTIAN
Published: July 2017

Predicting the velocity response of glaciers to increased surface melt is a major topic of ongoing research with significant implications for accurate sea-level rise forecasting. In this study we use optical and radar satellite imagery as well as comparisons with historical ground measurements to produce a multi-decadal record of ice velocity variations on Penny Ice Cap, Baffin Island. Over the period 1985–2011, the six largest outlet glaciers on the ice cap decelerated by an average rate of 21 m a−1 over the 26 year period (0.81 m a−2), or 12% per decade. The change was not monotonic, however, as most glaciers accelerated until the 1990s, then decelerated. A comparison of recent imagery with historical velocity measurements on Highway Glacier, on the southern part of Penny Ice Cap, shows that this glacier decelerated by 71% between 1953 and 2009–11, from 57 to 17 m a−1. The recent slowdown of outlet glaciers has coincided with increases in mass loss, terminus retreat and an inferred reduction in basal sliding. Measured decelerations are greater than the total short-term variability measured from both seasonal and interannual fluctuations, and support the hypothesis that glacier thinning and/or increased meltwater production promotes a long-term reduction in ice motion.
Serum and tissue 25-OH vitamin D3 concentrations do not predict bone abnormalities and molecular markers of vitamin D metabolism in the hypovitaminosis D kyphotic pig model
Authors: Amundson Laura A. , Hernandez Laura L. , Crenshaw Thomas D.
Published: July 2017

The hypovitaminosis D kyphotic pig provides a model to study maternal vitamin D (D) carryover on gross and molecular characteristics of bone abnormalities in offspring. Excess maternal D is proposed to protect offspring under nutritional challenges from developing bone abnormalities. Relationships between D sufficiency parameters and bone abnormalities were characterised. Sows (n 37) were fed diets with 0 (−D), 8·125 (+D) or 43·750 (++D) µg D3/kg throughout gestation and lactation. At weaning (3 weeks) pigs were fed diets with 0 (−D) or 7·0 (+D) µg D3/kg, each with 75 and 95 % (LCaP) or 150 and 120 % (HCaP) of the Ca and P requirements. Pigs were euthanised before colostrum consumption at birth (n 27), 3 weeks (n 27) or after the nursery period (7 weeks, n 71) for tissue analysis. At 7 weeks, differences due to maternal D were detected (P≤0·05) in pig growth, serum parameters and mRNA expression regardless of nursery diet. Prevalence of kyphosis in pigs at 13 weeks was affected by maternal D, but not prevented by only HCaP or +D nursery diets. Increased (P≤0·05) serum 25-OH-D3 concentrations in sows fed +D or ++D diets were not reflected by similar magnitudes of 25-OH-D3 in colostrum, 18-d milk, or serum and tissue concentrations in pigs. The mode of action by which maternal dietary D influences development of skeletal abnormalities warrants further investigation.
Disturbance induced dynamics of a tritrophic novel ecosystem
Authors: Lakatos K.T. , László Z. , Tóthmérész B.
Published: July 2017

Novel ecosystems formed by invasive plants provide a good opportunity to get insight into early dynamics and pattern formation of these ecosystems. The invasive black locust as host plant, Bruchophagus robiniae as host-specific seed predator and its parasitoids were the components of the studied tritrophic system. To investigate disturbance-driven dynamics of this system we created seed-vacated host plant patches in a field experiment. We removed all pods from selected patches of black locust resulting in an induced local extinction of seed predators and their parasitoids. We hypothesized that disturbance enhances top-down control by parasitoids; this enhanced top-down control decreases seed predation, facilitating the host plant's spread. We found that disturbance modified only parasitism after controlling with year effect: in vacated patches median parasitism was higher than in control patches. Seed predation exceeded its initial level in vacated patches in the third year after the disturbance, but in the fourth year it dropped again presumably due to the strong top-down control. Our findings also suggested that the seed predator was also affected by the bottom-up control of its host plant's density. We found that in the studied new ecosystem the top-down control was strengthened by the disturbance. Since the host plant of the tritrophic system is an invasive species, partial habitat disturbance of such species may increase the severity of parasitoid top-down control, which may reduce seed predation by the herbivores.
‘NONSENSE’ IN COMIC SCHOLIA
Authors: Kidd Stephen E.
Published: July 2017

In 1968 E.K. Borthwick, with a brilliant conjecture, cleared up a passage from Aristophanes’Peacethat had been considered ‘nonsense’ since antiquity. ‘Bell goldfinch’ (κώδων ἀκαλανθίς) the line seemed to be saying: a jumbled idea at best, gibberish at worst (1078). The scholium reads ad loc.: ταῦτα δὲ πάντα ἐπίτηδες ἀδιανοήτως ἔφρασεν, ‘all this is said as deliberate nonsense’, and later scholars generally follow suit (W.W. Merry, for example, in his 1900 edition ofPeacerefers to the line as ‘magnificent nonsense’). But Borthwick showed that this was not the case: ‘even nonsense expressions in Aristophanes’, he writes, ‘are not haphazard collocations of incongruous words signifying nothing’. What, then, to do with the ancient scholar (and those later ones) who failed to understand the passage, claiming it instead to be ‘nonsense’?
SINGING HEAVEN ON EARTH: COPTIC COUNTERPUBLICS AND POPULAR SONG AT EGYPTIANMŪLIDFESTIVALS
Authors: Ramzy Carolyn M.
Published: July 2017

This article explores the performative politics of devotional soundscapes at Coptic Christianmūlidfestivals. Echoing the state's reformist efforts in the 1990s to transform Muslim saint festivals into utilitarian spaces and their goers into “modern” Egyptian citizens, today the Coptic Church works to refashion these popular festivals from places of debauchery into morally productive spaces. Aided by affluent Cairene-based volunteers, church choirs travel from Cairo's poshest neighborhoods to these festivals to actively sing, disseminate, and teach popular religious songs (taratīl) in an effort to develop poorer Christian pilgrims into modern, pious, and more audible “citizens of heaven.” Through the analysis of one church choir'staratīlministry at themūlid, I illustrate how middle-class spiritual volunteers disrupt and, at times, reinscribe the Coptic Church's disciplinary efforts on the festival's poorer pilgrims, particularly as they look to modernize popular festivity into grounds of Christian ethical transformation.
THE SOCIAL LIFE OF ACADEMIC DISCOURSE: REFLECTIONS ON THE ANALYSIS OF PIETY POLITICS
Authors: Cakir Dunya D.
Published: July 2017

Examining the writings of prominent Islamist women intellectuals in Turkey, including Fatma Barbarosoğlu, Cihan Aktaş, Yıldız Ramazanoğlu, and Nazife Şişman, this article explores the repercussions of their intellectual activism for how scholars understand and study piety politics. These Islamist women intellectuals, whose discourse and subjectivities have been translated into analytical categories by scholars of piety politics, contest the terms of their encounters with academics and, more broadly, the conversion of Muslim women into objects of research. Their writings shed light on the complex interpretative interplay between academic and lay discourse when the objects of scholarly study speak back to social scientists. I argue that these kinds of critical engagements between Islamist women intellectuals and social scientific discourses attest to the mobility and circularity of social scientific categories, which have infused and reconstituted Islamist debates in Turkey. Rather than uncritically endorse or dispute these intellectuals’ interpretations of social scientific accounts, I leverage their claims to underscore the social life of academic discourse and to promote an enriched vision of piety politics and reflexive methodology.
CLEANSING THE NATION OF THE “DOGS OF HELL”: ʿALI JUMʿA'S NATIONALIST LEGAL REASONING IN SUPPORT OF THE 2013 EGYPTIAN COUP AND ITS BLOODY AFTERMATH
Authors: Warren David H.
Published: July 2017

This article contributes to an emerging scholarly debate over the support displayed by key Azhari ʿulamaʾ for the 3 July 2013 coup in Egypt and the subsequent massacres of anticoup protesters. I focus on the Islamic legal justifications articulated by the former grand mufti of Egypt ʿAli Jumʿa, which academics have contextualized primarily in relation to quietist precedents from late medieval Islamic political thought or his Sufi background. By contrast, I consider Jumʿa's justifications as representative of a nationalist discourse that has its historical origins in the protonationalism of Rifaʿa al-Tahtawi (d. 1873). My argument has wider implications for our conceptualization of the contemporary Islamic tradition. If, as scholars have argued, the Islamic tradition is a framework for inquiry rather than a set of doctrines, then in the 19th century a concern for the nation and its future became a key part of that framework. I contend that these additions came to redefine the worldview and politics of the ʿulamaʾ in terms of national progress and its horizon of expectations.
Interpreting the Oil Kingdom: Opportunities and Hazards
Authors: Samin Nadav
Published: July 2017

It is telling that Cambridge University Press commissioned two anthropologists to write its histories of modern Yemen and Saudi Arabia. Having escaped the experience of direct colonial rule, these countries do not fit comfortably into the dominant model of modern Middle Eastern history. It follows that the template for modern Saudi statehood cannot be retrieved from the colonial archives, or the postcolonial corporate ones, for that matter. Instead, it must be cobbled out of disparate parts, some Arabian, some Islamic, and some imported. Few modern states defy the reigning scholarly consensuses of economics, politics, history, and anthropology like Saudi Arabia, a place that on account of oil wealth has been transformed almost beyond recognition in the span of two or three generations.

Background

Body image disturbance (BID) is a core symptom of anorexia nervosa (AN), but as yet distinctive features of BID are unknown. The present study aimed at disentangling perceptual and attitudinal components of BID in AN.

Methods

We investigated n = 24 women with AN and n = 24 controls. Based on a three-dimensional (3D) body scan, we created realistic virtual 3D bodies (avatars) for each participant that were varied through a range of ±20% of the participants’ weights. Avatars were presented in a virtual reality mirror scenario. Using different psychophysical tasks, participants identified and adjusted their actual and their desired body weight. To test for general perceptual biases in estimating body weight, a second experiment investigated perception of weight and shape matched avatars with another identity.

Results

Women with AN and controls underestimated their weight, with a trend that women with AN underestimated more. The average desired body of controls had normal weight while the average desired weight of women with AN corresponded to extreme AN (DSM-5). Correlation analyses revealed that desired body weight, but not accuracy of weight estimation, was associated with eating disorder symptoms. In the second experiment, both groups estimated accurately while the most attractive body was similar to Experiment 1.

Conclusions

Our results contradict the widespread assumption that patients with AN overestimate their body weight due to visual distortions. Rather, they illustrate that BID might be driven by distorted attitudes with regard to the desired body. Clinical interventions should aim at helping patients with AN to change their desired weight.

Published: July 2017

Background

Autism spectrum disorders (ASD) are characterized by substantial clinical, etiological and neurobiological heterogeneity. Despite this heterogeneity, previous imaging studies have highlighted the role of specific cortical and subcortical structures in ASD and have forwarded the notion of an ASD specific neuroanatomy in which abnormalities in brain structures are present that can be used for diagnostic classification approaches.

Method

A large (N = 859, 6–27 years, IQ 70–130) multi-center structural magnetic resonance imaging dataset was examined to specifically test ASD diagnostic effects regarding (sub)cortical volumes.

Results

Despite the large sample size, we found virtually no main effects of ASD diagnosis. Yet, several significant two- and three-way interaction effects of diagnosis by age by gender were found.

Conclusion

The neuroanatomy of ASD does not exist, but is highly age and gender dependent. Implications for approaches of stratification of ASD into more homogeneous subtypes are discussed.
On the unique predual problem for Lipschitz spaces
Authors: WEAVER NIK

For any metric space X, the predual of Lip(X) is unique. If X has finite diameter or is complete and convex—in particular, if it is a Banach space—then the predual of Lip0(X) is unique.
Formation and suppression of acoustic memories during human sleep
Authors: Andrillon Thomas , Pressnitzer Daniel , Léger Damien , Kouider Sid
Published: July 2017

Sleep and memory are deeply related, but the nature of the neuroplastic processes induced by sleep remains unclear. Here, we report that memory traces can be both formed or suppressed during sleep, depending on sleep phase. We played samples of acoustic noise to sleeping human listeners. Repeated exposure to a novel noise during Rapid Eye Movements (REM) or light non-REM (NREM) sleep leads to improvements in behavioral performance upon awakening. Strikingly, the same exposure during deep NREM sleep leads to impaired performance upon awakening. Electroencephalographic markers of learning extracted during sleep confirm a dissociation between sleep facilitating memory formation (light NREM and REM sleep) and sleep suppressing learning (deep NREM sleep). We can trace these neural changes back to transient sleep events, such as spindles for memory facilitation and slow waves for suppression. Thus, highly selective memory processes are active during human sleep, with intertwined episodes of facilitative and suppressive plasticity.
Compositionally-distinct ultra-low velocity zones on Earth’s core-mantle boundary

Published: July 2017

The Earth’s lowermost mantle large low velocity provinces are accompanied by small-scale ultralow velocity zones in localized regions on the core-mantle boundary. Large low velocity provinces are hypothesized to be caused by large-scale compositional heterogeneity (i.e., thermochemical piles). The origin of ultralow velocity zones, however, remains elusive. Here we perform three-dimensional geodynamical calculations to show that the current locations and shapes of ultralow velocity zones are related to their cause. We find that the hottest lowermost mantle regions are commonly located well within the interiors of thermochemical piles. In contrast, accumulations of ultradense compositionally distinct material occur as discontinuous patches along the margins of thermochemical piles and have asymmetrical cross-sectional shape. Furthermore, the lateral morphology of these patches provides insight into mantle flow directions and long-term stability. The global distribution and large variations of morphology of ultralow velocity zones validate a compositionally distinct origin for most ultralow velocity zones.

Published: July 2017

The complex antiferromagnetic orders observed in the honeycomb iridates are a double-edged sword in the search for a quantum spin-liquid: both attesting that the magnetic interactions provide many of the necessary ingredients, while simultaneously impeding access. Focus has naturally been drawn to the unusual magnetic orders that hint at the underlying spin correlations. However, the study of any particular broken symmetry state generally provides little clue about the possibility of other nearby ground states. Here we use magnetic fields approaching 100 Tesla to reveal the extent of the spin correlations in γ-lithium iridate. We find that a small component of field along the magnetic easy-axis melts long-range order, revealing a bistable, strongly correlated spin state. Far from the usual destruction of antiferromagnetism via spin polarization, the high-field state possesses only a small fraction of the total iridium moment, without evidence for long-range order up to the highest attainable magnetic fields.
A highly attenuating and frequency tailorable annular hole phononic crystal for surface acoustic waves

Published: July 2017

Surface acoustic wave (SAW) devices are widely used for signal processing, sensing and increasingly for lab-on-a-chip applications. Phononic crystals can control the propagation of SAW, analogous to photonic crystals, enabling components such as waveguides and cavities. Here we present an approach for the realisation of robust, tailorable SAW phononic crystals, based on annular holes patterned in a SAW substrate. Using simulations and experiments, we show that this geometry supports local resonances which create highly attenuating phononic bandgaps at frequencies with negligible coupling of SAWs into other modes, even for relatively shallow features. The enormous bandgap attenuation is up to an order-of-magnitude larger than that achieved with a pillar phononic crystal of the same size, enabling effective phononic crystals to be made up of smaller numbers of elements. This work transforms the ability to exploit phononic crystals for developing novel SAW device concepts, mirroring contemporary progress in photonic crystals.
Semaphorin 4C Plexin-B2 signaling in peripheral sensory neurons is pronociceptive in a model of inflammatory pain

Published: July 2017

Semaphorins and their transmembrane receptors, Plexins, are key regulators of axon guidance and development of neuronal connectivity. B-type Plexins respond to Class IV semaphorins and mediate a variety of developmental functions. Here we report that the expression of Plexin-B2 and its high-affinity ligand, Sema4C, persists in peripheral sensory neurons in adult life and is markedly increased in states of persistent pain in mice. Genetic deletion of Sema4C as well as adult-onset loss of Plexin-B2 leads to impairment of the development and duration of inflammatory hypersensitivity. Remarkably, unlike the neurodevelopmental functions of Plexin-B2 that solely rely on Ras signaling, we obtained genetic and pharmacological evidence for a requirement of RhoA-ROCK-dependent mechanisms as well as TRPA1 sensitization in pronociceptive functions of Sema4C-Plexin-B2 signaling in adult life. These results suggest important roles for Plexin-B2 signaling in sensory function that may be of therapeutic relevance in pathological pain.

Published: July 2017

Maximum entropy estimation is of broad interest for inferring properties of systems across many disciplines. Using a recently introduced technique for estimating the maximum entropy of a set of random discrete variables when conditioning on bivariate mutual informations and univariate entropies, we show how this can be used to estimate the direct network connectivity between interacting units from observed activity. As a generic example, we consider phase oscillators and show that our approach is typically superior to simply using the mutual information. In addition, we propose a nonparametric formulation of connected informations, used to test the explanatory power of a network description in general. We give an illustrative example showing how this agrees with the existing parametric formulation, and demonstrate its applicability and advantages for resting-state human brain networks, for which we also discuss its direct effective connectivity. Finally, we generalize to continuous random variables and vastly expand the types of information-theoretic quantities one can condition on. This allows us to establish significant advantages of this approach over existing ones. Not only does our method perform favorably in the undersampled regime, where existing methods fail, but it also can be dramatically less computationally expensive as the cardinality of the variables increases.

Bioprinting is an emerging technique for the fabrication of living tissues that allows cells to be arranged in predetermined three-dimensional (3D) architectures. However, to date, there are limited examples of bioprinted constructs containing multiple cell types patterned at high-resolution. Here we present a low-cost process that employs 3D printing of aqueous droplets containing mammalian cells to produce robust, patterned constructs in oil, which were reproducibly transferred to culture medium. Human embryonic kidney (HEK) cells and ovine mesenchymal stem cells (oMSCs) were printed at tissue-relevant densities (107 cells mL−1) and a high droplet resolution of 1 nL. High-resolution 3D geometries were printed with features of ≤200 μm; these included an arborised cell junction, a diagonal-plane junction and an osteochondral interface. The printed cells showed high viability (90% on average) and HEK cells within the printed structures were shown to proliferate under culture conditions. Significantly, a five-week tissue engineering study demonstrated that printed oMSCs could be differentiated down the chondrogenic lineage to generate cartilage-like structures containing type II collagen.
