Published: April 2017

The present paper provides a combined application of X‐ray diffraction (XRD) and X‐ray fluorescence (XRF) methods in process control for the analysis of aluminum baths of different compositions. Developed approaches to the combined calibration XRD and XRF methods, independent calibration XRF techniques and to the full‐profile automated Rietveld analysis of a bath composition are described.We established that combined XRD–XRF calibration techniques provide an accurate stable analysis of technological parameters in a wide range of traditional and low‐melting compositions due to an accurate quantification of CaF2, MgF2 and KF additives. The developed XRF techniques provide quantitative analysis of both cryolite ratio and alumina with the accuracy of 0.03 and 0.25% wt. respectively, which is comparable with the technologically required accuracy.The evolutionary approach that automates full profile quantitative XRD analysis of bath composition and uses XRF data on Ca and Mg provides a better accuracy of measuring cryolite ratio compared to an accuracy of non‐automated analysis by Rietveld method.Combined application of the two X‐ray methods eliminates gross analytical errors and stabilizes overall performance of a smelter's process control system.

Published: April 2017

AbstractObjectiveIn 2011, Canada had a foreign-born population of approximately 6,775,800. They represented 20.6% of the total population. Immigrants possess characteristics that reduce the use of primary care. This is thought to be, in part, due to a lower education level, employment, and better health status. Our objective was to assess whether, in an immigrant population without a primary care physician, similar socioeconomic factors would also reduce the likelihood of using the emergency department compared to a non-immigrant population without primary care.MethodsData regarding individuals ≥ 12 years of age from the Canadian Community Health Survey from 2007 to 2008 were analysed (n=134,073; response rate 93%). Our study population comprised 15,554 individuals identified without a primary care physician who had a regular place for medical care. The primary outcome was emergency department as a regular care access point. Socioeconomic variables included employment, health status, and education. Covariates included chronic health conditions, mobility, gender, age, and mental health. Weighted logistic regression models were constructed to evaluate the importance of individual risk factors.ResultsThe sample of 15,554 (immigrants n=1,767) consisted of 57.3% male and 42.7% female respondents from across Canada. Immigrants were less likely than Canadian-born respondents to use the emergency department as a regular access point for health care (odds ratio=0.48 [95% CI 0.40 – 0.57]). Adjusting for health, education, or employment had no effect on this reduced tendency (odds ratio=0.47 [95% CI 0.38 – 0.58]).ConclusionIn a Canadian population without a primary care physician, immigrants are less likely to use the emergency department as a primary access point for care than Canadian-born respondents. However, this effect is independent of previously reported social and economic factors that impact use of primary care. Immigration status is an important but complex component of racial and ethnic disparity in the use of health care in Canada.

ObjectiveBipolar disorder (BD) patients have recently been shown to exhibit increased proinflammatory cytokine levels indicating the role of inflammation in this disease. As inflammatory responses often include complement level alterations and complement production is influenced by cytokines, we aimed to find out whether complement system is activated in BD in a time-dependent manner and complement factors are involved in BD pathogenesis.MethodsSerum C4, factor B, sC5b-9 and neuron-specific enolase levels were measured by enzyme-linked immunosorbent assay, whereas peripheral blood mononuclear cell messenger RNA (mRNA) expression levels of C1q, C4, factor B and CD55 were measured by real-time polymerase chain reaction in chronic BD patients (n=22), first episode BD patients (n=24) and healthy controls (n=19).ResultsSerum complement levels were significantly reduced in chronic BD patients as compared with first episode BD patients and healthy controls. Serum levels of complement factors showed significant inverse correlation with disease duration, severity of manic symptoms and serum neuron-specific enolase levels. In chronic BD patients, peripheral blood mononuclear cell mRNA expression levels of C1q, C4 and factor B were significantly elevated, whereas the mRNA expression level of the complement inhibitor CD55 was significantly reduced.ConclusionsOur results suggest that complement factor levels are reduced in BD presumably due to overconsumption of the complement system and complement production is increased at mRNA level possibly as a compensation measure. Complement factors might potentially be used as indicators of disease severity, neuronal loss and cognitive dysfunction.

AbstractPoaching is cryptically but rapidly driving many species towards extinction. Knowledge of population trends of exploited species and incentives for poaching is necessary to inform appropriate conservation measures. We estimated the abundance of four ungulate species in Golestan National Park, Iran, the country's oldest protected area, where poaching of ungulates is widespread. We used line transect surveys (186 km), camera trapping (2,777 camera-nights), point counts (64 scans) and dung counts (along 38 km), and compared population estimates with those from earlier records. We also investigated the incentives for poaching, using a semi-structured interview survey. Population estimates for 2011–2014 indicated a 66–89% decline in three ungulate species (bezoar goatCapra aegagrus, red deerCervus elaphusand urialOvis vignei) compared to 1970–1978. Only wild boarSus scrofashowed a population increase (of 58%) during the same period, possibly facilitated by religious restrictions regarding the consumption of this species. The incentives for poaching were categorized (in a non-ordinal manner) as subsistence, pleasure, tradition, trade of wild meat, and conflict with conservation regulations and bodies. The decline in hunted ungulates in this Park appears to be the result of rampant poaching, and a similar trend is evident in other protected areas in the country. We suggest the adoption of participatory conservation strategies, improvement of law enforcement practices and cooperation with international experts to reduce poaching in these protected areas. Taking into account the incentives for poaching, a combination of economic and non-economic strategies should be considered.
Why Rawls Can't Support Liberal Neutrality: The Case of Special Treatment for Religion
Authors: Koppelman Andrew 
Published: April 2017

AbstractSome arguments against the law’s special treatment of religion are adapted from Rawls. These overlook the ways in which the abstract rights agreed to in the original position are given specific institutional form at the constitutional stage. Because the rights established in the original position are vaguely specified, liberty of conscience can’t be implemented without reliance on contestable values such as religion. Public reason, when refracted through the four-stage sequence (where it becomes less constraining at each stage of the sequence), is far less constraining than the proponents of liberal neutrality hope. Fulfilling the commitments made in the original position, for people in the world here and now, requires taking account of the values that those people hold. A Rawlsian position thus can support the American regime of religious accommodation.

AbstractThe present report used data from the Minnesota Longitudinal Study of Risk and Adaptation to investigate the factor structure and childhood abuse and/or neglect related antecedents of adults’ attachment states of mind in a high-risk sample. Adult Attachment Interviews (AAIs) were collected when participants were age 26 years (N= 164) and Current Relationship Interviews (CRIs) were collected from participants (N= 116) and their romantic partners when target participants were between ages 20 and 28 years (M= 25.3 years). For both the AAI and the CRI, exploratory factor analyses revealed that (a) attachment state of mind scales loaded on two weakly correlated dimensions reflecting dismissing and preoccupied states of mind and (b) ratings of unresolved discourse loaded on the same factor as indicators of preoccupied states of mind. Experiencing any subtype of abuse and/or neglect, especially during multiple developmental periods, and experiencing multiple subtypes of abuse and/or neglect during childhood were associated with risk for preoccupied (but not dismissing) AAI states of mind regarding childhood relationships with caregivers. Analyses focused on the particular subtypes, and perpetrators indicated that the predictive significance of childhood abuse/neglect for adult's AAI preoccupied states of mind was specific to experiences of abuse (but not neglect) perpetrated by primary caregivers. In addition, experiencing chronic or multiple subtypes of childhood abuse and/or neglect increased risk for dismissing (but not preoccupied) CRI states of mind regarding adult romantic partners.

AbstractThis study examined whether the association between age and amygdala–medial prefrontal cortex (mPFC) connectivity in typically developing 6- to 10-year-old children is correlated with parental care. Resting-state functional magnetic resonance imaging scans were acquired from 124 children of the Generation R Study who at 4 years old had been observed interacting with their parents to assess maternal and paternal sensitivity. Amygdala functional connectivity was assessed using a general linear model with the amygdalae time series as explanatory variables. Higher level analyses assessing Sensitivity × Age as well as exploratory Sensitivity × Age × Gender interaction effects were performed restricted to voxels in the mPFC. We found significant Sensitivity × Age interaction effects on amygdala–mPFC connectivity. Age was related to stronger amygdala–mPFC connectivity in children with a lower combined parental sensitivity score (b= 0.11,p= .004,b= 0.06,p= .06, right and left amygdala, respectively), but not in children with a higher parental sensitivity score, (b= –0.07,p= .12,b= –0.06,p= .12, right and left amygdala, respectively). A similar effect was found for maternal sensitivity, with stronger amygdala–mPFC connectivity in children with less sensitive mothers. Exploratory (parental, maternal, paternal) Sensitivity × Age × Gender interaction analyses suggested that this effect was especially pronounced in girls. Amygdala-mPFC resting-state functional connectivity has been shown to increase from age 10.5 years onward, implying that the positive association between age and amygdala–mPFC connectivity in 6- to 10-year-old children of less sensitive parents represents accelerated development of the amygdala–mPFC circuit.

Published: April 2017

AbstractAlthough evidence shows that attachment insecurity and disorganization increase risk for the development of psychopathology (Fearon, Bakermans-Kranenburg, van IJzendoorn, Lapsley, & Roisman, 2010; Groh, Roisman, van IJzendoorn, Bakermans-Kranenburg, & Fearon, 2012), implementation challenges have precluded dissemination of attachment interventions on the broad scale at which they are needed. The Circle of Security–Parenting Intervention (COS-P; Cooper, Hoffman, & Powell, 2009), designed with broad implementation in mind, addresses this gap by training community service providers to use a manualized, video-based program to help caregivers provide a secure base and a safe haven for their children. The present study is a randomized controlled trial of COS-P in a low-income sample of Head Start enrolled children and their mothers. Mothers (N= 141; 75 intervention, 66 waitlist control) completed a baseline assessment and returned with their children after the 10-week intervention for the outcome assessment, which included the Strange Situation. Intent to treat analyses revealed a main effect for maternal response to child distress, with mothers assigned to COS-P reporting fewer unsupportive (but not more supportive) responses to distress than control group mothers, and a main effect for one dimension of child executive functioning (inhibitory control but not cognitive flexibility when maternal age and marital status were controlled), with intervention group children showing greater control. There were, however, no main effects of intervention for child attachment or behavior problems. Exploratory follow-up analyses suggested intervention effects were moderated by maternal attachment style or depressive symptoms, with moderated intervention effects emerging for child attachment security and disorganization, but not avoidance; for inhibitory control but not cognitive flexibility; and for child internalizing but not externalizing behavior problems. This initial randomized controlled trial of the efficacy of COS-P sets the stage for further exploration of “what works for whom” in attachment intervention.

AbstractThe design and synthesis of new stimuli-responsive hydrogen-bonding monomers that display a diversity of self-assembly pathways is of central importance in supramolecular chemistry. Here we describe the aggregation properties of a simple, intrinsically C2-symmetric enantiopure bicyclic cavity compound bearing a terminally unsubstituted ureidopyrimidinone fragment fused with a pyrrole moiety in different solvents and in the absence and presence of C60 and C70 guests. The tetrameric cyclic aggregate is selectively obtained in chlorinated solvents, where only part of the available hydrogen bonding sites are utilized, whereas in toluene or upon addition of C70 guests, further aggregation into tubular supramolecular polymers is achieved. The open-end cyclic assemblies rearrange into a closed-shell capsule upon introduction of C60 with an accompanied symmetry breaking of the monomer. Our study demonstrates that a C60 switch can be used to simultaneously control the topology and occupancy of tubular assemblies resulting from the aggregation of small monomers.

AbstractLettuce (Lactuca sativa) is a major crop and a member of the large, highly successful Compositae family of flowering plants. Here we present a reference assembly for the species and family. This was generated using whole-genome shotgun Illumina reads plusin vitroproximity ligation data to create large superscaffolds; it was validated genetically and superscaffolds were oriented in genetic bins ordered along nine chromosomal pseudomolecules. We identify several genomic features that may have contributed to the success of the family, including genes encodingCycloidea-like transcription factors, kinases, enzymes involved in rubber biosynthesis and disease resistance proteins that are expanded in the genome. We characterize 21 novel microRNAs, one of which may trigger phasiRNAs from numerous kinase transcripts. We provide evidence for a whole-genome triplication event specific but basal to the Compositae. We detect 26% of the genome in triplicated regions containing 30% of all genes that are enriched for regulatory sequences and depleted for genes involved in defence.

AbstractCarbon-based three-dimensional aerographite networks, built from interconnected hollow tubular tetrapods of multilayer graphene, are ultra-lightweight materials recently discovered and ideal for advanced multifunctional applications. In order to predict the bulk mechanical behaviour of networks it is very important to understand the mechanics of their individual building blocks. Here we characterize the mechanical response of single aerographite tetrapods via in situ scanning electron and atomic force microscopy measurements. To understand the acquired results, which show that the overall behaviour of the tetrapod is governed by the buckling of the central joint, a mechanical nonlinear model was developed, introducing the concept of the buckling hinge. Finite element method simulations elucidate the governing buckling phenomena. The results are then generalized for tetrapods of different size-scales and shapes. These basic findings will permit better understanding of the mechanical response of the related networks and the design of similar aerogels based on graphene and other two-dimensional materials.

AbstractThe Josephson effect is a fundamental quantum phenomenon where a dissipationless supercurrent is introduced in a weak link between two superconducting electrodes by Andreev reflections. The physical details and topology of the junction drastically modify the properties of the supercurrent and a strong enhancement of the critical supercurrent is expected to occur when the topology of the junction allows an emergence of Majorana bound states. Here we report charge transport measurements in mesoscopic Josephson junctions formed by InAs nanowires and Ti/Al superconducting leads. Our main observation is a colossal enhancement of the critical supercurrent induced by an external magnetic field applied perpendicular to the substrate. This striking and anomalous supercurrent enhancement cannot be described by any known conventional phenomenon of Josephson junctions. We consider these results in the context of topological superconductivity, and show that the observed critical supercurrent enhancement is compatible with a magnetic field-induced topological transition.
On the discrepancy between observed and CMIP5 multi-model simulated Barents Sea winter sea ice decline
Authors: Li Dawei , Zhang Rong , Knutson Thomas R. 
Published: April 2017

AbstractThis study aims to understand the relative roles of external forcing versus internal climate variability in causing the observed Barents Sea winter sea ice extent (SIE) decline since 1979. We identify major discrepancies in the spatial patterns of winter Northern Hemisphere sea ice concentration trends over the satellite period between observations and CMIP5 multi-model mean externally forced response. The CMIP5 externally forced decline in Barents Sea winter SIE is much weaker than that observed. Across CMIP5 ensemble members, March Barents Sea SIE trends have little correlation with global mean surface air temperature trends, but are strongly anti-correlated with trends in Atlantic heat transport across the Barents Sea Opening (BSO). Further comparison with control simulations from coupled climate models suggests that enhanced Atlantic heat transport across the BSO associated with regional internal variability may have played a leading role in the observed decline in winter Barents Sea SIE since 1979.
