Background

There is limited data on the beneficial effects of probiotics on the gingival health of patients undergoing treatment with fixed orthodontic appliances. This study aims to compare the effect of probiotic tablets combined with regular oral hygiene versus regular oral hygiene alone on gingival status in these patients. The effect of probiotic intake on plaque formation and salivary microbiome composition will be also assessed.

Methods and analysis

This is a 3 month single-centre, single blind (clinical and laboratory examiners), parallel group randomised controlled two arm superiority trial. Fifty paediatric patients attending the Postgraduate Orthodontic Clinic at the Hamdan Bin Mohammed College of Dental Medicine (HBMCDM), Mohammed Bin Rashid University of Medicine and Health Sciences (MBRU), Dubai, United Arab Emirates, who meet the eligibility criteria will be recruited. Block randomisation with 1:1 allocation and concealment of allocation will be carried out. The treatment group will receive probiotic tablets containingStreptococcus salivariusM18 andLactobacillus acidophilustogether with regular oral hygiene versus the control group on regular oral hygiene alone. Clinical examination and collection of saliva for microbiome assay will be carried out at baseline and end of study. Self-reporting by patients will be used to document acceptability and adverse effects. Statistically significant decrease in gingival bleeding on probing in the treatment group will be classified as primary outcome of treatment success. Statistically significant reduction in Plaque Index, Gingival Index and shift in the composition of the oral microbiome in favour of beneficial bacteria are secondary outcomes indicative of efficacy of probiotic intake.

Ethics and dissemination

Ethical approval for the study has been granted by the HBMCDM, MBRU, Institutional Review Board (Reference #: MBRU-IRB-2018–015). Study findings will be disseminated via publication in peer-reviewed journal.

The Chaplygin gas as a model for modified teleparallel gravity?
Authors: Sahlu Shambel , Ntahompagaze Joseph , Elmardi Maye , Abebe Amare
Published: September 2019

This paper explores the possibility of treating the exotic Chaplygin-gas (CG) fluid model as some manifestation of an f(T) gravitation. To this end, we use the different cosmological CG equations of state, compare them with the equation of state for the modified teleparallel gravity and reconstruct the corresponding Lagrangian densities. We then explicitly derive the equation of state parameter of the torsion fluid $$w_T$$wT and study its evolution for vacuum-torsion, radiation-torsion, dust-torsion, stiff fluid-torsion and radiation-dust-torsion multi-fluid systems. The obtained Lagrangians have, in general, matter dependence due to the matter-torsion coupling appearing in the energy density and pressure terms of the modified teleparallel gravity theory. For the simplest CG models, however, it is possibly to reconstruct f(T) Lagrangians that depend explicitly on the torsion scalar T only. The preliminary results show that, in addition to providing Chaplygin-gas-like solutions to the modified teleparallel gravitation, which naturally behave like dark matter and dark energy at early and late times respectively, the technique can be used to overcome some of the challenges attributed to the CG cosmological alternative.

Authors: Haskovec Jan , Markowich Peter , Pilli Giulia
Published: September 2019

We demonstrate the validity of Murray’s law, which represents a scaling relation for branch conductivities in a transportation network, for discrete and continuum models of biological networks. We first consider discrete networks with general metabolic coefficient and multiple branching nodes and derive a generalization of the classical 3/4-law. Next we prove an analogue of the discrete Murray’s law for the continuum system obtained in the continuum limit of the discrete model on a rectangular mesh. Finally, we consider a continuum model derived from phenomenological considerations and show the validity of the Murray’s law for its linearly stable steady states.

The possibility for the existence of the exotic [Formula: see text] states is explored with the objective of calculating the [Formula: see text] momentum distribution inside such nuclei. Even though the latter is an essential ingredient for the analysis of the experimental data on the [Formula: see text], [Formula: see text] and [Formula: see text] reactions aimed at finding an [Formula: see text]-mesic 3He, the data analysis is usually performed by approximating the [Formula: see text] momentum distribution by that of a nucleon. Here, we present calculations performed by solving the three-body Faddeev equations to obtain the momentum distribution of the [Formula: see text] inside possible ([Formula: see text])[Formula: see text], ([Formula: see text])[Formula: see text] and ([Formula: see text])[Formula: see text]-[Formula: see text] states. The [Formula: see text] momentum distributions are found to be much narrower than those of the nucleons and influence the data selection criteria.

Authors: Hossienkhani H. , Azimi N. , Zarei Z.
Published: September 2019

Recent observers have shown that an anisotropy cosmic expansion may exist. In this work, we study the effects of low anisotropy with Bianchi type I model using the current observational data, which includes the supernova Legacy Survey (SNLS) sample of 238 SN events ([Formula: see text]) and 1048 Pantheon sample confirmed type Ia supernova (SNIa) covering the redshift range [Formula: see text]. Assuming an anisotropic universe, we use the two parametrizations of the dark energy equation-of-state, such as the [Formula: see text] (PA) and [Formula: see text] (PB), and then we fit the SNIa light-curve parameters and free cosmological parameters, simultaneously employing maximum likelihood estimation method. When combining the Baryon Acoustic Oscillations (BAO) and the observational Hubble data (OHD) measurements with the SNLS SN sample, we find [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] for the PA model and [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] for the PB model. When combining also Pantheon data, we obtain [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] for the PA model and [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] for the PB model. The analysis shows that by considering the anisotropy effects, it leads to more best-fit parameters in [Formula: see text]CDM model with the current observational data.
Heteroleptic palladium(II) complexes of dipyrrin-1,9-dione supported by intramolecular hydrogen bonding
Authors: Curtis Clayton J. , Tomat Elisa
Published: September 2019

The dipyrrin-1,9-dione framework, which is characteristic of the propentdyopent pigments deriving from heme metabolism, coordinates metal ions as monoanionic bidentate donors. The resulting analogs of dipyrrinato complexes undergo reversible ligand-based reductions, thus showcasing the ability of the dipyrrindione scaffold to act as an electron reservoir. Herein we report the synthesis and characterization of three heteroleptic palladium complexes of the redox-active dipyrrindione ligand. Primary amines were chosen as additional ligands so as to assemble complexes of planar geometries with complementary interligand hydrogen-bonding. Full chemical characterization confirms the hydrogen bonding interactions between the primary amine ligands and the acceptor carbonyl groups on the dipyrrolic ligand. The resulting heteroleptic compounds display reversible one-electron reduction events that are centered on the dipyrrindione ligand as revealed by voltammetry and spectroelectrochemistry data. Within these planar Pd(II) complexes, the propentdyopent motif therefore combines reversible ligand-based redox chemistry with interligand hydrogen bonding in the primary coordination sphere of the metal center.
Meso-1,4-phenylene bridged nickel norcorrole dimer
Authors: Shin Ji-Young
Published: September 2019

Nickel norcorrole dimer 3 linked with a phenylene bridge was prepared by a nickel-mediated homolytic cross-coupling of meso-phenylene bisdipyrrin nickel(II) dimer 2b. The structures of 2b and 3 were elucidated by X-ray diffraction analysis. Each nickel norcorrole fraction of the nickel norcorrole dimer 3 exposed a bowl-like structure, which conserved anti-conformation. Structural distinctions between the monomeric and dimeric nickel norcorroles were established by vibrational spectroscopic analysis and assessed with density functional theory calculations. Enhanced flexibility of the norcorrole planes in solution states of monomeric nickel norcorrole was compromised to that of bowl-shaped norcorroles in the solid states of nickel norcorrole dimer 3, where C[Formula: see text] was the formulated conformation. The deformation of the planarity derived from the objection of laser pulses effectuated vibration shifts of specific Raman-active motions toward a higher-frequency region, as associating with a paratropic nature of the [Formula: see text]-electron delocalization circuit of norcorrole. Computational simulation exposed a reliable drift of the Raman frequencies.
Alkylation, metalation and ring contraction of tropiporphyrin
Authors: Lash Timothy D. , Rooney John M.
Published: September 2019

Tropiporphyrins are an intriguing class of carbaporphyrinoids that incorporate a cycloheptatriene subunit. Previous investigations have shown that this system acts as a trianionic ligand that can form stable silver(III) complexes. In this work, tropiporphyrin was reacted with excess methyl iodide and potassium carbonate in refluxing acetone to give an internally alkylated derivative. The reaction occurred regioselectively to introduce a methyl group onto the 24-position. Reaction with palladium(II) acetate afforded a palladium(II) complex that retained the [Formula: see text]-methyl substituent. In contrast, reaction of [Formula: see text]-unsubstituted tropiporphyrin with palladium(II) acetate gave two palladium(II) benziporphyrins, one of which possessed a formyl substituent. Although these organometallic derivatives were obtained in relatively low yields, the observation of unexpected ring contraction products demonstrates that the reactivity of the tropiporphyrin system deserves to be further investigated.
Sparse recovery with general frame via general-dual-based analysis Dantzig selector

Published: September 2019

This paper considers recovery of signals that are sparse or approximately sparse in terms of a general frame from undersampled data corrupted with additive noise. We show that the properly constrained [Formula: see text]-analysis, called general-dual-based analysis Dantzig selector, stably recovers a signal which is nearly sparse in terms of a general dual frame provided that the measurement matrix satisfies a restricted isometry property adapted to the general frame. As a special case, we consider the Gaussian noise.
Improving Adaptive Video Streaming through Session Classification

Published: September 2019

With internet video gaining increasing popularity and soaring to dominate network traffic, extensive studies are being carried out on how to achieve higher Quality of Experience (QoE) with the delivery of video content. Associated with the chunk-based streaming protocol, Adaptive Bitrate (ABR) algorithms have recently emerged to cope with the diverse and fluctuating network conditions by dynamically adjusting bitrates for future chunks. This inevitably involves predicting the future throughput of a video session. Some of the session features like Internet Service Provider (ISP), geographical location, and so on, could affect network conditions and contain helpful information for this throughput prediction. In this article, we consider how our knowledge about the session features can be utilized to improve ABR quality via customized parameter settings. We present our ABR-independent, QoE-driven, feature-based partition method to classify the logged video sessions so that different parameter settings could be adopted in different situations to reach better quality. A
variation
of Decision Tree is developed for the classification and has been applied to a sample ABR for evaluation. The experiment shows that our approach can improve the average bitrate of the sample ABR by 36.1% without causing the increase of the rebuffering ratio where 99% of the sessions can get improvement. It can also improve the rebuffering ratio by 87.7% without causing the decrease of the average bitrate, where, among those sessions involved in rebuffering, 82% receives improvement and 18% remains the same.

Authors: Owaida Muhsen , Kulkarni Amit , Alonso Gustavo
Published: September 2019

Given the growth in data inputs and application complexity, it is often the case that a single hardware accelerator is not enough to solve a given problem. In particular, the computational demands and I/O of many tasks in machine learning often require a cluster of accelerators to make a relevant difference in performance. In this article, we explore the efficient construction of FPGA clusters using inference over Decision Tree Ensembles as the target application. The article explores several levels of the problem: (1) a lightweight inter-FPGA communication protocol and routing layer to facilitate the communication between the different FPGAs, (2) the data partitioning and distribution strategies maximizing performance, (3) and an in depth analysis on how applications can be efficiently distributed over such a cluster. The experimental analysis shows that the resulting system can support inference over decision tree ensembles at a significantly higher throughput than that achieved by existing systems.
Stable Specification Search in Structural Equation Models with Latent Variables
Authors: Rahmadi Ridho , Groot Perry , Heskes Tom
Published: September 2019

In our previous study, we introduced stable specification search for cross-sectional data (S3C). It is an exploratory causal method that combines the concept of stability selection and multi-objective optimization to search for stable and parsimonious causal structures across the entire range of model complexities. S3C, however, is designed to model causal relations among observed variables. In this study, we extended S3C to S3C-Latent, to model linear causal relations between latent variables that are measured through observed proxies. We evaluated S3C-Latent on simulated data and compared the results to those of PC-MIMBuild, an extension of the PC algorithm, the state-of-the-art causal discovery method. The comparison shows that S3C-Latent achieved better performance. We also applied S3C-Latent to real-world data of children with attention deficit/hyperactivity disorder and data about measuring mental abilities among pupils. The results are consistent with those of previous studies.
ThumbStroke
Authors: Lai Jianwei , Zhang Dongsong , Wang Sen , Kilic Isil Doga Yakut , Zhou Lina
Published: September 2019

The QWERTY keyboard on mobile devices usually requires users’ full visual attention and both hands, which is not always possible. We propose a thumb-stroke-based keyboard, ThumbStroke, to support both sight-free and one-handed text entry. Text entry via ThumbStroke completely relies on the directions of thumb strokes at any place on the screen of a mobile device. It does not require physical press on any specific keys, thus eliminating the need for visual attention and reducing errors due to tiny key size, fat thumbs, limited thumb reachability, and visual occlusion. We empirically evaluated ThumbStroke through a 20-session longitudinal controlled lab experiment. ThumbStroke shows advantages in typing accuracy and user perceptions in comparison to the Escape and QWERTY keyboards and results in faster typing speed than QWERTY in sight-free and one-handed text entry. This study provides novel research contributions to mobile HCI, advancing the design of soft keyboards for one-handed interaction with mobile devices and mobile accessibility.
Cut Optimization for Redundant Via Insertion in Self-Aligned Double Patterning
Authors: Song Youngsoo , Hyun Daijoon , Lee Jingon , Jung Jinwook , Shin Youngsoo
Published: September 2019

Redundant via (RV) insertion helps prevent via defects and hence leads to yield enhancement. However, RV insertion in self-aligned double patterning (SADP) processes is challenging since cut optimization has to be considered together. In SADP, parallel one-dimensional metal lines are divided into signal wires and dummy wires by line-end cuts. If an RV is inserted, signal wires need to be extended to connect to the RV. To this end, an additional cut, which we call RV cut, is introduced to make a space for the extension. Since RV cuts and line-end cuts are manufactured with the same mask set, design rules between those cuts have to be honored, which incurs proper distribution and mask assignment to individual cuts. In this article, we address a problem of integrated RV insertion and cut optimization. We show that the problem can be formulated as an integer linear programming (ILP). We also propose a heuristic algorithm is presented for practical application, in which potential locations of RVs are first identified and used to properly insert as many RVs as possible while minimizing the conflict between RV cuts. Our experimental results demonstrate that 75% of vias receive RVs with 8% increase in total wire length, which is only slightly worse than the optimal result obtained by ILP.
MHC Class I Molecules Exacerbate Viral Infection by Disrupting Type I Interferon Signaling
Authors: Xia Simo , Tao Yijie , Cui Likun , Yu Yizhi , Xu Sheng
Published: September 2019

MHC class I molecules are key in the presentation of antigen and initiation of adaptive CD8+ T cell responses. In addition to its classical activity, MHC I may possess nonclassical functions. We have previously identified a regulatory role of MHC I in TLR signaling and antibacterial immunity. However, its role in innate antiviral immunity remains unknown. In this study, we found a reduced viral load in MHC I-deficient macrophages that was independent of type I IFN production. Mechanically, MHC I mediated viral suppression by inhibiting the type I IFN signaling pathway, which depends on SHP2. Cross-linking MHC I at the membrane increased SHP2 activation and further suppressed STAT1 phosphorylation. Therefore, our data revealed an inhibitory role of MHC I in type I IFN response to viral infection and expanded our understanding of MHC I and antigen presentation.
Nanoscale Structures and Hydrogen Storage Capacity of Fe-C-H Produced by Milling Graphite with Steel Balls in a Hydrogen Atmosphere
Authors: Wakayama Hiroaki
Published: September 2019

To elucidate the influence of Fe on the interaction between carbon and hydrogen in graphite nanocrystals, graphite nanocrystals were mechanically milled with steel balls in a hydrogen atmosphere, and the potential of the material produced to store hydrogen was evaluated. X-ray diffraction and Raman spectra revealed that milling reduced the graphene size and increased the average distance between graphene layers. Elemental analysis showed that milling increased both the H/C and Fe/C ratios in the material. After being milled in a hydrogen atmosphere, samples released hydrogen at a lower temperature than before milling. Thermal decomposition occurred in two stages—235 to 475°C and 692 to 749°C—and yielded a total of 1.0 wt% hydrogen. It is hypothesized that these two stages corresponded to hydrogen released from Fe3C structures and from the Fe-catalyzed graphitization reaction, respectively. Before milling, samples slowly released a total of 0.5 wt% hydrogen over a temperature range from about 300 to over 900°C. Fe-C-H materials are attractive for hydrogen storage because they are composed of carbon and iron, which are inexpensive and abundant elements on Earth, and they have a high hydrogen weight density of 11 wt%.

Authors: Laliotis Nikolaos , Chrysanthou Chrysanthos , Konstantinidis Panagiotis , Papadopoulou Lizeta
Published: September 2019

We present a case series of four children, younger than 3 years old, with osteoid osteoma of the lower limb. Pain and limping were the main symptoms. With careful clinical examination, we could localize the affected area. Radiological evaluation revealed cortical thickening in 3 children. On MRI examination, we found extensive edema, with normal bony cortices. The central nidus was found in 3 children. CT scan was the most accurate examination which revealed the central nidus with surrounding sclerosis. Bone scans had positive uptake in the affected area. Our patients were treated with an intralesional excision biopsy, with simultaneous radiofrequency ablation in those affected in the femur. Pathological specimens confirmed the diagnosis of osteoid osteoma. There was uneventful recovery of our patients. This case series contributes to the limited description of osteoid osteoma diagnosed and treated in very young children.
A Comparative Life Cycle Assessment (LCA) of Warm Mix Asphalt (WMA) and Hot Mix Asphalt (HMA) Pavement: A Case Study in China
Authors: Ma Hui , Zhang Zhigang , Zhao Xia , Wu Shuang
Published: September 2019

Generally, the warm mix asphalt (WMA) technology can reduce the mixing and paving temperature effectively as compared with that of hot mix asphalt (HMA), which is considered more environment‐friendly. In this study, the environmental impacts and resource consumptions of WMA and HMA pavements were analyzed comparatively using the life cycle assessment (LCA) method. A LCA model of pavement was built; meanwhile, the relevant life cycle inventory (LCI) of WMA and HMA pavements was also collected and analyzed. The midpoint impact categories including Global Warming Potential (GWP), Chinese Abiotic Depletion Potential (CADP), and Particulate Matter Formation (PMF) were assessed for five cases. The assessment results showed that the resource consumptions of both WMA and HMA pavements in entire life were almost at the same level, while the environmental impacts of WMA pavement related to greenhouse gases and PM2.5 emissions were significantly less than that of HMA pavement, except for the case where the long‐term performance of WMA pavement is much worse than that of HMA pavement. In final, it could be concluded that WMA pavement is more environment‐friendly compared with HMA pavement although they have the same‐level resource consumptions.
Tattooist-Associated Tattoo Complications: “Overworked Tattoo,” “Pigment Overload” and Infections Producing Early and Late Adverse Events
Authors: Hutton Carlsen Katrina , Sepehri Mitra , Serup Jørgen
Published: September 2019

Background: Tattooist-related technical failures of tattooing were hitherto unstudied and related to clinical complications. Tattooing requires talent, training and experience. Amateurism is a challenge in popular tattoo industry with no formal education and certification of the tattooists. Objective: To study technical tattoo failures causing disease in a consecutive hospital material of tattoo complications. Material: 574 patients with 702 tattoo complications referred to the “Tattoo Clinic” (a subspecialised dermatological clinic) were enrolled. Patients were examined clinically and classified with respect to the cause of complication. Results: 147 (21%) tattooist and tattoo studio-related complications were recorded, i.e. excessive pigment installed in the dermis with “pigment overload” in 64 (9%), tattoo “needle trauma” with “overworked tattoos” in 43 (6%), contaminated ink causing infection in 20 (3%), and other sources of infections related to tattooing in 20 (3%). Pain and discomfort were particularly common as well as long-term complications including scarring induced by “needle trauma.” “Pigment overload” with black pigment carried a special risk of granulomatous inflammation and sarcoid granuloma and was observed in 12/35 (34%) of punch biopsies taken from tattoos with “pigment overload.” Keratoacanthoma associated with trauma was observed in 1 case. 82% of complications were related to professional tattooists working in a tattoo studio and 18% to amateurs. Conclusion: Technical failures of tattooing are associated with medical tattoo complications. “Needle trauma” with major skin damage, e.g. “overworked tattoo,” and installation of excessive pigment, e.g. “pigment overload,” and (re)use of contaminated tattoo ink bottles are identified failures calling for preventive intervention.

Published: September 2019

Este artigo contribui para a literatura de desigualdades de oportunidades educacionais ao separar os determinantes do aprendizado entre circunstâncias e esforços, com foco na capacidade de atuação dos gestores das redes e das escolas. Os resultados mostram que entre 10% e 15% da desigualdade de notas está sob controle dos órgãos centrais, mas fogem ao controle dos diretores escolares. A metodologia também permite estimar em que medida as circunstâncias afetam a desigualdade de notas via interação com os esforços dos gestores. Os resultados mostram que entre 10% e 23% da desigualdade atribuída ao perfil dos alunos pode ser influenciada por políticas educacionais. Estes resultados sugerem que os esforços dos gestores podem amenizar os efeitos das circunstâncias sobre a desigualdade.

The Indian net-casting spider name Deinopis goalparaensis Tikader & Malhotra is a nomen dubium (Araneae: Deinopidae)
Authors: CALEB JOHN T.D.
Published: September 2019

The genus Deinopis was established by MacLeay (1839) with D. lamia MacLeay, 1839 as its type species. It is the most speciose deinopid genus presently comprising 51 described species, of which two are known from India (World Spider Catalog 2019). The genus was first recorded from India with the description of the species, Deinopis goalparaensis Tikader and Malhotra, 1978 from Assam, which was described based on the females only (Tikader & Malhotra 1978) and the male still remains unknown. Thirty-six years later another species, Deinopis scrubjunglei Caleb & Mathai, 2014 was described from Chennai, Tamil Nadu based on both sexes (Caleb & Mathai 2014). Apart from these taxonomic accounts, Satam et al. (2015) provided notes on the microhabitat utilization of juvenile Deinopis spiders from Mumbai. With no other supportive studies and additional data on these spiders, Indian deinopids remain obscure and inadequately known. The goal of the present communication is to provide clarification on the taxonomic status of the poorly known Indian species D. goalparaensis, supported with illustrations.
Mesenchymal Sufu Regulates Development of Mandibular Molars via Shh Signaling
Authors: Li J. , Xu J. , Cui Y. , Wang L. , Wang B. , Wang Q. , Zhang X. , Qiu M. , Zhang Z.
Published: September 2019

Sonic hedgehog ( Shh) in dental epithelium regulates tooth morphogenesis by epithelial-mesenchymal signaling transduction. However, the action of Shh signaling regulation in this process is not well understood. Here we find that mesenchymal Suppressor of Fused ( Sufu), a major negative regulator of Shh signaling, plays an important role in modulating the tooth germ morphogenesis during the bud-to-cap stage transition. Deletion of Sufu in dental mesenchyme by Dermo1-Cre mice leads to delayed development of mandibular molar into cap stage with defect of primary enamel knot (EK) formation. We show the disruption of cell proliferation and programmed cell death in dental epithelium and mesenchyme in Sufu mutants. Epithelial-specific adhesion molecule E-cadherin is evidently reduced in the bilateral basal cells of tooth germ at E14.5. The cells in the presumptive EK, predominantly expressing P-cadherin, appear stratified but fail to condense. Moreover, the transcripts of primary EK marker genes, including Shh, Fgf4, and p21, are significantly decreased compared to controls. In contrast, we find that deficiency of Sufu results in elevation of Shh signaling in mesenchyme, indicated by the significant upregulation of Gli1 and Ptch1. Meanwhile, the expression of Bmp4 and Fgf3, the critical factors of mesenchymal-epithelial induction, is significantly inhibited in dental mesenchyme. Furthermore, the expression of Runx2 experiences a transient decrease at the bud stage. Taken together, these data suggest that mesenchymal Sufu is necessary for tuning the Shh signaling, which may act as an upstream modulator of Bmp4 and Fgf3 to coordinate the interplay between the dental mesenchyme and epithelium of tooth germ.
Against the Script With edTPA: Preservice Teachers Utilize Performance Assessment to Teach Outside Scripted Curriculum
Authors: Ahmed Kathryn Struthers
Published: September 2019

This article reports on how the policy context shaped the development of two elementary preservice teachers’ (PSTs) literacy instructional practice. While student teaching emergent bilingual students in urban, high-poverty classrooms that utilized mandated scripted literacy curriculum, PSTs completed edTPA, a Teacher Performance Assessment, for their credential. Participants’ edTPA lessons represented the only time PSTs taught literacy outside the mandated curriculum’s script and in ways that were more aligned with their—and their teacher education program’s—ideals. Findings from this study show that it might be possible for PSTs and teacher educators to appropriate edTPA for their own purposes.
Urbanisation processes and new towns in contemporary China: A critical understanding from a decentred view
Authors: Governa Francesca , Sampieri Angelo
Published: September 2019

The article discusses the results of research on Chinese new towns focusing on three places: Tongzhou New Town, located in the eastern suburban expansion of Beijing; Zhaoqing New Area, currently being built approximately 20 km from the old city of Zhaoqing (Guandong Province); and Zhengdong New District, located near Zhengzhou (inland Henan Province). Tongzhou, Zhaoqing and Zhengdong have absolutely nothing in common: location, size, spaces, economies, inhabitants, or when and how they were built. However, studying these places allowed us to identify two issues that still seem to be in need of investigation both empirically and theoretically: the spatial features and regional scaling-up of the Chinese urbanisation processes. While presenting these issues, on the one hand, the article emphasises their specificity in the investigated contexts and, on the other, it transcends these specific cases in order to question urban studies beyond the (alleged) exceptionality of Chinese urbanisation. By adopting this approach, Chinese new towns become an object of study as well as a specific viewpoint from which to examine contemporary urbanisation and radically re-discuss old categories, conceptualisations and even the epistemology of the urban.
Local environmental governance and policy implementation: Variegated environmental education in three districts in Tianjin, China
Authors: Luova Outi
Published: September 2019

Variation in the implementation of environmental policies in urban China has received widespread scholarly attention, but the extensive heterogeneity in local governance frameworks has remained under-studied. Leaning on the abundant, new institutionalism theory, this article suggests that the concept of institutional configuration can bring structure to the analysis of local complex governance frameworks and help identify factors that create different approaches to environmental policies. This study analyses the construction of approaches to new environmental education policies in three urban districts in Tianjin to illustrate how the suggested conceptual framework applies to centrally administered Chinese cities. The findings show that different combinations of formal and socio-cultural factors emerge as decisive in the institutional configuration of each district. This study also reveals new interesting nuances in the motivations behind environmental policy implementation.
Situation model updating in young and older adults
Authors: Hoeben Mannaert Lara , Dijkstra Katinka
Published: September 2019

Over the past decade or so, developments in language comprehension research in the domain of cognitive aging have converged on support for resilience in older adults with regard to situation model updating when reading texts. Several studies have shown that even though age-related declines in language comprehension appear at the level of the surface form and text base of the text, these age differences do not apply to the creation and updating of situation models. In fact, older adults seem more sensitive to certain manipulations of situation model updating. This article presents a review of theories on situation model updating as well how they match with research on situation model updating in younger and older adults. Factors that may be responsible for the resilience of language comprehension in older age will be discussed as well as avenues for future research.
Cross-cultural comparison of maternal mind-mindedness among Australian and Chinese mothers
Authors: Dai Qian , McMahon Catherine , Lim Ai Keow
Published: September 2019

Evidence suggests that parental mind-mindedness is important for children’s social-emotional development; however, almost all research exploring mind-mindedness has been conducted with families from Western backgrounds. The current study explored cross-cultural differences in mind-mindedness based on observed real-time interactions between urban Australian ( N = 50, M age = 30.34 years, SD = 3.14) and urban mainland Chinese ( N = 50, M age = 29.18 years, SD = 4.14) mothers and their toddlers (Australian: M age = 18.98 months, SD = 0.87; Chinese: M age = 18.50 months, SD = 2.25). Controlling for education, the Australian mothers used a higher proportion of appropriate mind-related comments and were less likely to use non-attuned mind-related comments than their Chinese counterparts, adjusting for total number of comments. Transcript analysis showed that the Australian mothers used more mental state terms referring to desires and preferences than Chinese mothers. Findings are discussed in relation to cultural influences in child-rearing goals, beliefs, and values and the need for cross-cultural validation of the mind-mindedness construct.
Consuming Indigeneity: Baba Ramdev, Patanjali Ayurveda and the Swadeshi Project of Development
Authors: Tripathy Jyotirmaya
Published: September 2019

How does the discourse of indigeneity converse with the imperatives of economic and cultural globalization in a postcolonial state like India? The complexity of the question and the possibility of multi-layered responses become all the more intriguing when such a discourse is promoted by Ramdev, a yoga guru turned entrepreneur. Responding to the question, the article focuses on the role of tradition in normative development thought and its mainstreaming in a culture-conscious India, the postcolonial desire for Swadeshi (exemplified in Patanjali Ayurveda) and the possibility of a consumption pattern that goes beyond individual gratification. To begin with, the article draws from a recent controversy which brought into popular discussion the attitude of foreign companies vis-à-vis cultural sentiments. It addresses the question of tradition in Western development theory and how that theorization is interrogated in contemporary development practices. Then it traces the evolution of Swadeshi as an attempt at epistemic and economic autonomy and how such thinking is co-opted by Ramdev in advancing the fortunes of Patanjali. This deployment of Swadeshi vocabulary is then combined with the practice of consumption that is loaded with associations of indigeneity and nationalism. In the process, the article offers a template for reworking some of the common sensical assumptions about tradition, development and consumption.

Guidelines are fundamental in addressing everyday clinical indications and in reporting the current evidence-based data of related scientific investigations. At the same time, a spatial and temporal issue can limit their value. Indeed, variability in the recommendations can be found both among the same nation different scientific societies and among different nations/continents. On the other side, Garcia already published in 2014 data showing how, after three years in average, one out of five recommendations gets outdated (Martinez Garcia LM, Sanabria AJ, Garcia Alvarez E, et al. The validity of recommendations from clinical guidelines: a survival analysis. CMAJ 2014;186(16):1211–1219). The present document reports a narrative literature revision on the major international recommendations in lower limb venous and lymphatic disease management, focusing on the different countries’ guidelines, trends and controversies from all the continents, while identifying new evidence-based data potentially influencing future guidelines. World renowned experts’ opinions are also provided. The document has been written following the recorded round tables scientific discussions held at the vWINter international meeting (22–26 January 2019; Cortina d’Ampezzo, Italy) and the pre- and post-meeting literature search performed by the leading experts.

Objective:

To evaluate the frequency of neoadjuvant therapy (NT) in women with stage I–III breast cancer in Italy and whether it is influenced by biological characteristics, screening history, and geographic area.

Methods:

Data from the High Resolution Study conducted in 7 Italian cancer registries were used; they are a representative sample of incident cancers in the study period (2009–2013). Included were 3546 women aged <85 years (groups <50, 50–69, 70–64, and 75+) with stage I–III breast cancer at diagnosis who underwent surgery. Women were classified as receiving NT if they received chemotherapy, target therapy, and/or hormone therapy before the first surgical treatment. Logistic models were built to test the association with biological and contextual variables.

Results:

Only 8.2% of women (290 cases) underwent NT; the treatment decreases with increasing age (14.5% in age <50 and 2.2% in age 75+), is more frequent in women with negative receptors (14.8%), HER2-positive (15.7%), and triple-negative (15.6%). The multivariable analysis showed the probability of receiving NT is higher in stage III (odds ratio [OR] 3.83; 95% confidence interval [CI] 2.83–5.18), luminal B (OR 1.87; 95% CI 1.27–2.76), triple-negatives (OR 1.88; 95% CI 1.15–3.08), and in symptomatic cancers (OR 1.98; 95% CI 1.13–3.48). Use of NT varied among geographic areas: Reggio Emilia had the highest rates (OR 2.29; 95% CI 1.37–3.82) while Palermo had the lowest (OR 0.41; 95% CI 0.24–0.68).

Conclusions:

The use of NT in Italy is limited and variable. There are no signs of greater use in hospitals with more advanced care.
Pharmacist-Delivered Patient Care in an Interdisciplinary Team-Based Institutional Palliative Care Clinic, 2012 to 2018
Authors: Dayer Lindsey E. , McDade Elizabeth R. , Harrington Sarah
Published: September 2019

Palliative care services offered in the United States have grown substantially since the year 2000. These types of services have been shown to improve a patient’s quality of life when presented with a serious or life-threatening disease or illness. An important characteristic of a quality palliative care service is the presence of an interdisciplinary team to utilize different areas of expertise to address multiple aspects of patient care. An important member of this team is the pharmacist. The services presented in this interprofessional education and practice guide describe pharmacist-delivered palliative care services offered in an institutional ambulatory palliative care setting from 2012 to 2018.
Women’s Perceptions of Safety After Domestic Violence: Exploring Experiences of a Safety Contact Program
Authors: Westwood Tania , Wendt Sarah , Seymour Kate
Published: September 2019

This article explores women’s experiences of the women’s safety services associated with a South Australian integrated program for male perpetrators of domestic and family violence. As small scale and exploratory, the study aimed to understand impact of such services on women’s perceptions of safety. Interviews were conducted by telephone, using a semi-structured format, with 14 women whose partners or ex-partners had been referred to a perpetrator intervention program. Informed by a feminist standpoint perspective, thematic analysis was used to explore each woman’s experience and perception of safety. The findings of the study suggest that integrated domestic and family violence programs can improve women’s feelings of safety through the application of practical safety planning, timely intervention, emotional support, and trauma-focused practice. Importantly, while the behaviors and actions of perpetrators were clearly relevant to women’s perceived safety, it was apparent that focusing on women’s strengths and capacity for recovery can significantly impact on their continued sense of safety and well-being. This article also reiterates the importance of women’s perspectives in evaluating the effectiveness of perpetrator interventions.
Constructing Spiritual Motherhood in the Democratic Republic of Congo
Authors: Clevenger Casey
Published: September 2019

Drawing on an ethnographic study of Roman Catholic sisters in the Democratic Republic of Congo, I show how women in the Global South draw on religious imagery to redefine cultural ideals of womanhood and family responsibility. By taking the religious vows of chastity, poverty, and obedience, the Congolese sisters I interviewed seemingly betray local expectations regarding women’s responsibility to reproduce and repair the clan. Although sisters’ vows subject them to social ridicule for violating cultural expectations to bear children and support kin, they devise new strategies to negotiate the connection between womanhood and the maternal role of caregiver and nurturer outside of marriage and fertility. In social ministries that affirm their communal, moral, and spiritual ties to others, the sisters realize these cultural ideals through a “spiritual motherhood” that transforms their traditional heteronormative obligations. Framing their decision to live outside accepted kinship structures in religious terms mutes the radicalness of this lifestyle and provides religious legitimation for what would otherwise be considered a selfish choice for a woman acting independent of family well-being. In this context, I demonstrate how doing religion is inseparable from doing gender as Catholic sisters embody alternative ways of being a woman in post-colonial Congolese society through their religious practices.
