Making Memories: Time and Responsibility in Intermedial Metatheatre
Authors: Gasoi Lowell 
Published: November 2019

That performance can be captured and replayed may be a given, but much less well-understood is the relationship between that stored performance, the memory of a performed act, and the live event. The practice of intermedial theatre offers a unique way to probe that relationship, and the awareness of metatheatre further exposes the links between memory, technology, and performance. This paper argues that intermedial metatheatre, and my own work as a director, video-maker, and video performer for a 2014 production of Daniel MacIvor’s play Never Swim Alone, provides a valuable model for research-creation that can shed light on these questions in an embodied and experiential manner. Engaging with Sarah Kember and Joanna Zylisnka’s notion of performative media, as well as the concept of memory work from Annette Kuhn, I offer thoughts on materiality, time, and mediated memory, captured through technologies like camera and sound recording equipment, and in constructed spaces like studios and rehearsal rooms, represented by projection mapping software and digital projectors in the theatre space. All these are integrated into the network of actors and techniques that make up current practices in intermedial theatrical creation. Can this research begin to unravel ideas of authenticity and liveness when reactivating memories in relation to live actors, and before an audience? And what of our responsibility to the digital representation and the live performer when bringing these memories and moments together? How does the network of technologies and practitioners in intermedial theatre creation and presentation, understand and respect the “lifeness” of a mediated memory?

Authors: Zhou Siming , Tao Zhengbo , Zhu Yue , Tao Lin 
Published: November 2019

Background
This study aimed to draw a series of scientific maps to quantitatively and qualitatively evaluate hot spots and trends in postmenopausal osteoporosis research using bibliometric analysis.

Methods
Scientific papers published on postmenopausal osteoporosis were extracted from the Web of Science Core Collection and PubMed database. Extracted information was analyzed quantitatively with bibliometric analysis by CiteSpace, the Online Analysis Platform of Literature Metrology and Bibliographic Item Co-Occurrence Matrix Builder (BICOMB). To explore the hot spots in this field, co-word biclustering analysis was conducted by gCLUTO based on the major MeSH terms/MeSH subheading terms-source literatures matrix.

Results
We identified that a total of 5,247 publications related to postmenopausal osteoporosis were published between 2013 and 2017. The overall trend decreased from 1,071 literatures in 2013 to 1,048 literatures in 2017. Osteoporosis International is the leading journal in the field of postmenopausal osteoporosis research, both in terms of impact factor score (3.819) and H-index value (157). The United States has retained a top position and has exerted a pivotal influence in this field. The University of California, San Francisco was identified as a leading institution for research collaboration, and Professors Reginster and Kanis have made great achievements in this area. Eight research hot spots were identified.

Conclusions
Our study found that in the past few years, the etiology and drug treatment of postmenopausal osteoporosis have been research hot spots. They provide a basis for the study of the pathogenesis of osteoporosis and guidelines for the drug treatment of osteoporosis.

Type 1 DM remained the commonest type of DM. Most of the patients were of the middle social class (social class III). Challenges to management included high cost of investigations and drugs, high rate of loss to follow up.
Conclusion: Pubertal disorders, type 1 Diabetes mellitus, thyroid disorders, calcium and phosphate metabolism and bone disorders and obesity were the commonest cases in our review. Most investigations were available in private laboratories with high cost of investigation leading to loss to follow up and continuation of care.
Robust Working Mechanism of Water Droplet‐Driven Triboelectric Nanogenerator: Triboelectric Output versus Dynamic Motion of Water Droplet
Authors: Yang Lei , Wang Yunfei , Guo Yanjie , Zhang Weiqiang , Zhao Zhibin 
Published: November 2019

AbstractHarvesting energy from water flow based on liquid–solid contact electrification has been receiving intensive attention recently. However, due to the high deformability of water, challenges remain on exploring the dynamic motion of water in relation to the electrical output characteristic of water‐based triboelectric nanogenerator (TENG). Herein, by measuring the electrical output of a water droplet‐driven TENG (Wd‐TENG) along with observing the dynamics of the droplets by a high‐speed camera, a robust working mechanism of the Wd‐TENG is proposed, considering droplet spread, rebound, slide, and coalescence on the solid surface during the triboelectric cycle. It is demonstrated that the spread–rebound motion of droplet upon impact on the triboelectric layer surface results in one positive–negative current peak and the detachment of the droplet from the surface leads to another negative current peak. Droplet coalescence is also observed and found to cause larger negative peak when the merged droplet leaves the surface. The proposed mechanism is sufficiently proved by the results under different droplet dripping rates, sizes, surface wetting properties, and types of liquid. These findings provide an extended understanding of the liquid–solid contact electrification, which is significant in both fundamental and applied science of liquid–solid TENG.

AbstractThe vast majority of conjugated‐polymer‐based light emitting field‐effect transistors (LEFETs) are characterized by low charge‐carrier mobilities typically in the 10−5 to 10−3 cm2 V−1 s−1 range. Fast carrier transport is a highly desirable characteristic for high‐frequency LEFET operation and, potentially, for use in electrically pumped lasers. Unfortunately, high‐mobility organic semiconductors are often characterized by strong intermolecular π–π interactions that reduce luminescence. Development of new materials and/or device concepts that overcome this hurdle are therefore required. Single organic semiconductor layer based LEFETs that combine high hole mobilities with encouraging light emission characteristics are reported. This is achieved in a single polymer layer LEFET, which is further enhanced through the use of a small‐molecule/conjugated polymer blend system that possesses a film microstructure which supports enhanced charge‐carrier mobility (3.2 cm2 V−1 s−1) and promising light‐emission characteristics (1600 cd m−2) as compared to polymer‐only based LEFETs. This simple approach represents an attractive strategy to further advance the performance of solution‐processed LEFETs.
Japanese beef trade impact from BSE using a time‐varying Armington model
Authors: Soon Byung Min , Thompson Wyatt 
Published: November 2019

AbstractThis study examines the persistent impacts of the bovine spongiform encephalopathy (BSE) outbreak in the United States on Japanese beef demands. An Armington model with time‐varying parameters allows us to separate BSE effects from other factors. A counter‐factual case estimates that, if the BSE outbreak had not occurred, demand for Australian beef would have been lower and demand for U.S. beef would have been higher, with domestic beef demand only modestly affected. The BSE outbreak affected imported frozen beef demands more than imported chilled beef demands. Our estimation method is relevant for researchers studying the impacts of disease‐related or other trade disruptions, as well as to traders and policy makers with interest in Japanese beef markets.

Published: November 2019

AbstractRecently, emerging functions utilizing phenolic molecules, such as surface functionalizing agents or bioadhesives, have attracted significant interest. However, the most important role of phenolic compounds is to produce carbonized plant matter called “coal”, which is widely used as an energy source in nearly all countries. Coalification is a long‐term, high‐temperature process in which phenols are converted into conducting carbonized matter. This study focuses on mimicking coalification processes to create conducting sealants from non‐conducting phenolic compounds by heat treatment. We demonstrate that a phenolic adhesive, tri‐hydroxybenzene (known as pyrogallol), and polyethylenimine mixture initially acts as an adhesive sealant that can be converted to a conducting carbon sealing material. The conductivity of the phenolic sealant is about 850 Ω−1 cm−1, which is an approximately two‐fold enhancement of the performance of carbon matter. Applications of the biomimetic adhesives described herein include conducting defect sealants in carbon nanomaterials and conducting binders for metal/carbon or ceramic/carbon composites.

ObjectiveIncreased protein phosphatase magnesium‐dependent 1A (PPM1A) levels in patients with ankylosing spondylitis regulate osteoblast differentiation in bony ankylosis; however, the potential mechanisms that regulate osteoclast differentiation in relation to abnormal bone formation remain unclear. This study was undertaken to investigate the relationship of PPM1A to osteoclast differentiation by generating conditional gene‐knockout (PPM1Afl/fl;LysM‐Cre) mice and evaluating their bone phenotype.MethodsThe bone phenotypes of LysM‐Cre mice (n = 6) and PPM1Afl/fl;LysM‐Cre mice (n = 6) were assessed by micro–computed tomography. Osteoclast differentiation was induced by culturing bone marrow–derived macrophages in the presence of RANKL and macrophage colony‐stimulating factor (M‐CSF), and was evaluated by counting tartrate‐resistant acid phosphatase–positive multinucleated cells. Levels of messenger RNA for PPM1A, RANK, and osteoclast‐specific genes were examined by real‐time quantitative polymerase chain reaction, and protein levels were determined by Western blotting. Surface RANK expression was analyzed by fluorescence flow cytometry.ResultsThe PPM1Afl/fl;LysM‐Cre mice displayed reduced bone mass (P < 0.001) and increased osteoclast differentiation (P < 0.001) and osteoclast‐specific gene expression (P < 0.05) compared with their LysM‐Cre littermates. Mechanistically, reduced PPM1A function in osteoclast precursors in PPM1Afl/fl;LysM‐Cre mice induced osteoclast lineage commitment by up‐regulating RANK expression (P < 0.01) via p38 MAPK activation in response to M‐CSF. PPM1A expression in macrophages was decreased by Toll‐like receptor 4 activation (P < 0.05). The Ankylosing Spondylitis Disease Activity Score was negatively correlated with the expression of PPM1A in peripheral blood mononuclear cells from patients with axial spondyloarthritis (SpA) (γ = −0.7072, P < 0.0001).ConclusionThe loss of PPM1A function in osteoclast precursors driven by inflammatory signals contributes to osteoclast lineage commitment and differentiation by elevating RANK expression, reflecting a potential role of PPM1A in dynamic bone metabolism in axial SpA.
An exploration of the experiences that counsellors have of taking care of their own mental, emotional and spiritual well‐being
Authors: Barton Heather 
Published: November 2019

AbstractIntroductionThe purpose of this study was to explore the experiences of therapists in taking care of their own mental, emotional and spiritual well‐being. This is an under‐researched area that is of vital importance, not only for the well‐being of the therapists themselves, but also for their clients.AimThis qualitative study examined the experiences that counsellors have in taking care of their own mental, emotional and spiritual well‐being.MethodSemi‐structured qualitative interviews were conducted with five experienced therapists who had all been qualified for eight years or more. Data were thematically analysed within the overall principles of Interpretative Phenomenological Analysis.ResultsFour superordinate themes were identified. These concerned: (a) the demands and challenges that therapists face in their work, particularly when dealing with difficult clients and client issues; (b) the perception that the therapists have that their own preparation and training for taking care of themselves was inadequate; (c) growth for the therapists personally and in self‐awareness, learning their own limitations, building resilience and realising the necessity of prioritising self‐care; (d) therapists becoming more compassionate towards themselves, and finding ways of managing their own self‐care.DiscussionResults revealed that the process of managing good self‐care is a journey that begins with little or no knowledge of the importance of self‐care, to arriving at a point of realising its importance and making it a priority.Conclusion/ImplicationsGaps in training were highlighted along with a need to support broader understanding and recognition of the value of therapist self‐care.

AbstractThe recent advancement on the tailored synthesis of hypercrosslinked microporous polymer (HMP‐2) has assembled significant concentration by the virtue of its adjustable porosity, operative design and absolutely ordering structure. This perfectly structured Ag NPs supported carbocatalyst (Ag‐HMP‐2) has been synthesized by Friedel‐Crafts alkylation between 4,4′‐Bis(bromomethyl)‐1,1′‐biphenyl and carbazole over anhydrous iron(III)chloride catalysis followed by the appending of the silver nanoparticles (Ag NPs) onto the material. The silver nanoparticle was decorated over the HMP‐2 to prepare the corresponding catalyst (Ag‐HMP‐2). The characterization of the newly produced material has been conducted by N2 adsorption/desorption studies, XPS, FE‐SEM, transmission electron microscopy (TEM) and Powder X‐ray diffraction (PXRD) methods. This microporous catalyst has spectacular activities for the production of tetramic acids from various types of propargylic amine derivatives at 60 °C under atmospheric carbon dioxide pressure. Parallel attempt on fixation of CO2 was executed over terminal alkynes to synthesize propiolic acids under 1 atm pressure. The catalyst (Ag‐HMP‐2) exhibited sufficient recycling ability for the generation of tetramic acids and propiolic acids up to five catalytic runs without reduction in its catalytic activity.
Artificial Reactor with Alterable Tandem Channeling for the Formation of Self‐Screened Catalytic Ability

Published: November 2019

AbstractInspired by the polymeric “soft” properties and divisional isolation of tandem processes in natural systems, an artificial reactor with self‐screened catalytic ability was fabricated with a polymeric tri‐layer architecture. The non‐responsive middle layer encapsulated catalytic metal nanoparticles, while the two outer layers consisted of a negatively and a positively thermosensitive imprinted polymer. The inverse responsiveness of the outer layers induced switchable shapes, which led to alterable tandem channeling to the reactive middle layer and, as a result, the divisional admission of different substrates. This way, the reactor led to the formation of self‐screened catalytic ability. The design for this artificial reactor offers promising prospects for struggling tandem catalysts, suggesting opportunities to develop schedulable tandem processes.
Revealing the Effect of Nanopores in Biomass‐Derived Carbon on its Sodium‐Ion Storage Behavior
Authors: Wang Caiwei , Huang Jianfeng , Li Jiayin , Cao Liyun , Chen Qian , Qian Cheng , Chen Shaoyi 
Published: November 2019

AbstractThe sodium storage mechanism in biomass‐derived carbon is composed of absorption/desorption from defects, insertion/extraction between layers in pseudographitic domains, and nanopores filling. Nanopores are produced to provide spaces for sodium‐ion storage and diffusion, which attracts more attention. However, roles of nanopores in biomass‐derived carbon microstructure and their influences on electrochemical behavior of sodium‐ion batteries still need to be further explored. Therefore, we control nanopore size of biomass carbon by three different methods. Results show the size and distribution of nanopores have effect on uniformity of interlayer spacing in pseudographitic domains around pores. After cycling, the stability of nanopore structure plays an important role on sodium storage behavior. Without nanopores as buffer spaces, the diffusion resistance of sodium ions increases because of decreased interlayer spacing from outside to inside. When more micropores are formed with uniform interlayer spacing distribution, the structure of electrode is well‐maintained and higher specific capacity is achieved after sodium‐ion inserting/extracting. The formation of mesopores accompanies with nonuniform interlayer spacing. Mesopore structure tends to be destroyed easily by large amount of sodium ions inserting/extracting. Cracked parts provide unstable buffer space for sodium ions. The interlayer spacing in meso‐porous carbon tube increases rapidly after cycling, which leads to capacity loss.
Group 13 Precursor Structures and Their Effect on Oxide Nanocrystal Formation
Authors: Sommer Sanna , Gjerlevsen Nielsen Ida , Brummerstedt Iversen Bo 
Published: November 2019

AbstractPrecursor structures (PSs) in solution are expected to influence both nanocrystal formation mechanisms, as well as crystallization of specific polymorphs. Herein, Group 13 PS structures determined by pair distribution function and extended X‐ray absorption fine structure analysis are reported. Corner‐sharing octahedral dimers form from the metal nitrates dissolved in either water, isopropanol, or ethanol at room temperature contradicting previous studies that suggested monomers or larger Keggin clusters. Because all crystalline indium oxides have octahedral coordination, crystals can easily nucleate from the observed PSs. Similarly, MOOH (M=Al and Ga) with octahedral M coordination is expected to form readily from the PSs, whereas formation of γ‐M2O3 requires a partial conversion to tetrahedral M coordination. This explains the long‐standing observation of initial AlOOH formation as a bottleneck for γ‐Al2O3 synthesis. Different indium polymorphs crystallize from the various solvents, and thus there is no obvious link between the PSs and observed polymorphism.
