AbstractObjectivesTo develop computerized adaptive testing (CAT) and short forms of self‐report oral health measures that are predictive of both the children's oral health status index (COHSI) and the children's oral health referral recommendation (COHRR) scales, for children and adolescents, ages 8–17.Material and methodsUsing final item calibration parameters (discrimination and difficulty parameters) from the item response theory analysis, we performed post hoc CAT simulation. Items most frequently administered in the simulation were incorporated for possible inclusion in final oral health assessment toolkits, to select the best performing eight items for COHSI and COHRR.ResultsTwo previously identified unidimensional sets of self‐report items consisting of 19 items for the COHSI and 22 items for the COHRR were administered through CAT resulting in eight‐item short forms for both the COHSI and COHRR. Correlations between the simulated CAT scores and the full item bank representing the latent trait arer= .94 for COHSI andr= .96 for COHRR, respectively, which demonstrated high reliability of the CAT and short form.ConclusionsUsing established rigorous measurement development standards, the CAT and corresponding eight‐item short form items for COHSI and COHRR were developed to assess the oral health status of children and adolescents, ages 8–17. These measures demonstrated good psychometric properties and can have clinical utility in oral health screening and evaluation and clinical referral recommendations.

Authors: Da Giau Alessandro , Foss Nicolai J. , Furlan Andrea , Vinelli Andrea 
Published: December 2019

AbstractWe used the dynamic capabilities approach to study environmental sustainability and development in the fashion industry. To achieve green transformation, companies need to develop effective dynamic capabilities, which entails changing their current organizational design by realigning their activities, partnerships, and routines with the changed external environment. By means of three case studies, we identified the components of dynamic capabilities that can be instrumental in companies' innovation and adaptability toward sustainability goals. In particular, we examined how companies sensed market opportunities and threats, seized such opportunities, and reconfigured their internal assets. We also investigated how structural changes in these firms reflected their strategies for supporting sustainability development.

Published: December 2019

AbstractMetal‐free and totally organic based batteries were fabricated from functional polyethers. Aliphatic polyethers, in which 2,2,6,6‐tetramethylpiperidin‐1‐oxyl and viologen were introduced with high density, were used as the cathode and anode active materials, respectively. By stacking nanosheets of the polymers and an imidazolium‐substituted polyether as the electrolyte, a solid‐state cell only 2 μm thick was made. The anion‐type rocking‐chair cell showed reversible charge/discharge even at a high rate of 5 C without adding any solvents or plasticizers. Although the unsealed cell was measured under ambient conditions, no significant side reactions (including self‐discharging and capacity decay) occurred, whereas conventional electrodes are sensitive to air and water in the charged state. The intrinsic plasticity of the polyethers is also compatible with making free‐form, 3D‐printable batteries.

Published: December 2019

AbstractA novel method for the preparation of iron‐ and nitrogen‐codoped carbon nanotubes (Fe‐N‐CNTs) is proposed, based on the catalytic pyrolysis of waste plastics. First, carbon nanotubes are produced from pyrolysis of plastic waste over Fe‐Al2O3; then, Fe‐CNTs and melamine are heated together in an inert atmosphere. Different co‐pyrolysis temperatures are tested to optimize the electrocatalyst production. A high doping temperature improves the degree of graphite formation and promotes the conversion of nitrogen into a more stable form. Compared with commercial Pt/C, the electrocatalyst obtained from pyrolysis at 850 °C shows remarkable properties, with an onset potential of 0.943 V versus RHE and a half‐wave potential of 0.811 V versus RHE, and even better stability and anti‐poisoning properties. In addition, zinc–air battery tests are performed, and the optimized catalyst exhibits a high maximum power density.

Published: December 2019

AbstractThe diverse nature of organic precursors offers a versatile platform for precisely tailoring the electronic properties of semiconducting polymers. In this study, three fully conjugated sp2carbon‐linked polymers have been designed and synthesized for photocatalytic hydrogen evolution under visible‐light illumination, by copolymerizing differentC3‐symmetric aromatic aldehydes as knots with the 1,4‐phenylene diacetonitrile (PDAN) linker through a C=C condensation reaction. The hydrogen evolution (HER) is achieved at a maximum rate of 30.2 mmol g−1 h−1over a polymer based on 2,4,6‐triphenyl‐1,3,5‐triazine units linked by cyano‐substituted phenylene, with an apparent quantum yield (AQY) of 7.20 % at 420 nm. Increasing the degree of conjugation and planarity not only extends visible‐light absorption, but also stabilizes the fully conjugated sp2‐carbon‐linked donor–acceptor (D–A) polymer. Incorporating additional electron‐withdrawing triazine units into the D–A polymer to form multiple electron donors and acceptors can greatly promote exciton separation and charge transfer, thus significantly enhancing the photocatalytic activity.
Influence of the inverse sheath on divertor plasma performance in tokamak edge plasma simulations
Authors: Masline Rebecca , Smirnov Roman D. , Krasheninnikov Sergei I. 
Published: December 2019

AbstractRecently, it was shown that strong electron thermionic emission from material walls could result in the formation of an “inverse sheath,” which prevents the flow of cold ions to the wall.[1–3] Such regimes look very favourably from the point of view of plasma–material interactions at the edge of magnetic fusion devices, where the problem of the erosion of plasma‐facing components under ion irradiation is one of the key issues for the development of future magnetic fusion reactors. However, it is not clear whether such regimes are compatible with edge plasma parameters and heat removal requirements in fusion reactors. To address the issue of practicality of the “inverse sheath” regime for edge tokamak plasma conditions, we perform a set of numerical simulations with 2D edge plasma transport code UEDGE[4] for a DIII‐D‐like geometry and magnetic configuration. To describe both “standard” and “inverse sheath” conditions within the framework of the UEDGE code (which does not consider the sheath region per se), at the material surfaces, we apply effective boundary conditions that emulate both “standard” and “inverse sheath” regimes. We demonstrate that, for the same input parameters, spatial distributions of edge plasma parameters corresponding to detached divertor and “inverse sheath” regimes are similar, with only a few minor differences. We discuss the compatibility of “inverse sheath” regimes with core plasma parameters.

Published: December 2019

SummarySystem on a chip (SoC) creates massive design challenges for SoC‐based designers. The design challenges start from functional, architectural verification complexity and finally meeting performance constraints. In addition, heterogeneity of components and tools introduces long design cycles. The Software‐Defined System‐on‐Chip (SDSoC) developed by Xilinx is used to create custom SoC on a heterogeneous FPGA‐CPU platform. The SDSoC tool provides fast, flexible, and short design cycle to develop heterogeneous FPGA‐CPU platform. The objective of this paper is to introduce a new automated design technique to build a SoC on a heterogeneous FPGA‐CPU platform that meets design requirements using SDSoC tool. In this paper, the typical SDSoC design flow is introduced. In addition, a new automated SDSoC design technique is developed to design SoC on a heterogeneous FPGA‐CPU platform on the basis of performance metrics such as area, power, and latency. Design of physical downlink shared channel (PDSCH) in long‐term evolution (LTE) is presented as a case study. This paper provides the implementation of the transmitter and the receiver of the PDSCH in LTE using SDSoC tool and selects a platform that meets performance metrics constraints.

Published: December 2019

AbstractBackgroundPituicytoma is a rare tumor of the sella and suprasellar region. It is common for these tumors to be misdiagnosed radiographically as pituitary adenomas, meningiomas, and craniopharyngiomas. Histologically, pituicytomas are also known to show variable morphology. These factors often complicate intraoperative consultation, especially when tissue is limited.MethodsA database search (January 1990‐June 2019) identified 13 surgically resected pituicytomas that were sent for intraoperative consultation. The intraoperative cytology was reviewed by two pathologists, and both squash preparations/smears and touch preparations were included.ResultsThe cytological features of pituicytomas were variable. The cytoplasm ranged from fibrillary to fine and wispy. The nuclei were round to ovoid with occasional tumors showing spindled morphology. Small nucleoli were seen in all tumors, and chromatin was fine to vesicular. While squash preparations were cellular and revealed cohesive groups of tumor cells, touch preparations were often paucicellular with the exception of one tumor. The cytological features of pituicytomas are compared to those of other tumors with similar radiographic appearances.ConclusionsOur findings illustrate the range of cytological features of these rare tumors and highlight the difficulty in making a definitive intraoperative diagnosis. Pituicytomas should be considered in the differential of a sellar/suprasellar lesion with glial and meningioma‐like cytological features.
Payments for ecosystem services and conditional cash transfers in a policy mix: Microlevel interactions in Selva Lacandona, Mexico
Authors: Izquierdo‐Tort Santiago 
Published: December 2019

AbstractPayments for ecosystem services (PES) programs have been increasingly studied with a policy mix perspective. So far, the focus has been on PES' interplay with other conservation instruments and resulting environmental outcomes at meso‐ and macrolevels. Though PES often operate among “poor” forest‐dwelling communities in the Global South, our knowledge on PES' interactions with poverty alleviation policies is scarce, especially at the microlevel. This article examines PES' interactions—in terms of joint coverage, management, and spending of revenues, and socioeconomic effects of participation—with a conditional cash transfer (CCT) program in a case study of six communities in Selva Lacandona, Chiapas, Mexico. The article builds a dual framework combining policy mix analysis with an actor‐oriented approach focused on participants' microagency, and is based on in‐depth, qualitative research. Results reveal widespread joint PES and CCT coverage, and patterns of specialization between different household members regarding the management and spending of program revenues. Results also show positive, multilevel policy interactions as participants combine resources to pursue individual and collective socioeconomic strategies. The article highlights the creative ways in which local stakeholders integrate individual policies within their broader livelihoods, and how coordination failures among policy‐implementing institutions and deficient public services limit participants' ability to achieve sustained livelihood improvements. The article also highlights how a focus on microlevel policy interactions complements meso‐ and macrolevel analyses for a better understanding of PES' role in a policy mix and concludes by providing some recommendations for building implementation synergies and improving program design.
Compliance with European Union environmental law: An analysis of digitalization effects on institutional capacities
Authors: Bürgin Alexander 
Published: December 2019

AbstractThis article presents evidence for the positive effects of digitalization on the institutional capacity of key stakeholders, which is a necessary precondition for narrowing the existing implementation gap in European Union environmental law. Based on document analysis and semistructured interviews with actors involved in the implementation process, four main factors are considered. First, the Commission's institutional capacity benefits from a change of focus of the reporting system from textual information to data and indicators and by the development of new data harvesting methods. Second, subnational actors have improved their institutional capacity through knowledge transfers and strategic planning, facilitated by better information and communication technology and statistical data. Third, inspection networks benefitted from technical advances, such as the access to satellite images, presenting new opportunities for the detection of environmental crimes, and new software programs facilitating risk‐based inspections. Finally, citizens' and nongovernmental organizations' improved access to data and to justice in environmental matters strengthened their monitoring capacities.
Spillover of authenticity from work to home: The mediating role of affect
Authors: Zhang Hong , Chen Changkai , Schlegel Rebecca , Chen Kaiyuan 
Published: December 2019

AbstractA growing area of research is beginning to examine the state‐like nature of authenticity. The current study builds on this research by examining the (dis)continuity in state authenticity across two different social contexts: work and home. We surveyed 154 full‐time employees twice a day for five consecutive workdays. Results showed that state authenticity at work and at home shared a relatively strong positive relationship that appeared to be mediated by the spillover of affect from one context to the next. This is consistent with prior work showing that affect tends to “spillover” from one context to the next and work that suggests a causal impact of affect on authenticity judgments. Implications for the study of state authenticity as well as work–home interaction are discussed.
Bringing together humanistic and intergroup perspectives to build a model of internalisation of normative social harmdoing
Authors: Amiot Catherine E. , Lizzio‐Wilson Morgana , Thomas Emma F. , Louis Winnifred R. 
Published: December 2019

AbstractThis article introduces a model of the internalisation of normative social harmdoing: the MINSOH. This model seeks to explain how group members internalise harmful social norms such that they personally endorse their groups' normative actions. To this aim, the MINSOH integrates two divergent yet complementary theoretical perspectives: self‐determination theory and the social identity approach. These perspectives differ in their basic assumptions about the possibility for harm to become internalised, yet when integrated, they provide a powerful account of how harmdoing can become internalised. The MINSOH proposes specific conditions under which harmful normative actions become accepted by group members. This article outlines multiple self‐determined motivations for harmdoing and discrete group processes that enable harmdoing to be internalised and autonomously enacted, and reviews factors that facilitate (i.e., strong/unique/comparative social identification; endorsement of ideological justifications) and block the internalisation process (presence of multiple identities/diverging norms; inclusive superordinate identity). Directions for future research are then discussed.
Impact of high mobility III‐V compound material of a short channel thin‐film SiGe double gate junctionless MOSFET as a source
Authors: Rout Soumendra P. , Dutta Pradipta 
Published: December 2019

AbstractIn recent years, technology has embraced the use of Junctionless Double Gate Metal‐Oxide‐Semiconductor Field‐Effect Transistors (JL DGMOSFET) to reduce Short Channel Effects (SCEs). This research presents a novel JL DGMOSFET based on a highly doped N‐type SiGe in which an III‐V compound material is used at source regime. The III‐V compound material GaSb with higher mobility and higher injection velocity is used as source material, whereas SiGe is considered for both channel and drain materials to produce a higher output current and low leakage current for the N channel JL DGMOSFET. In addition, high‐k dielectric material HfO2 is employed to improve the controllability of the gate at 20 nm channel length. Different parameters, such as Id, SS, gm, TGF, Ion/Ioff ratio, Cgs, and fT of a Symmetric JL DGMOSFET are studied and compared to existing works. The comparison shows that the proposed JL DGMOSFET outperforms the existing state of knowledge. The analysis is also being extended by including the trap charge for the symmetric JL DGMOSFET. Parametrically, the asymmetrical structure is finally studied. The proposed structure yields a higher Id of 40 mA, SS of 60.25 mV/decade, gm of 0.148 A/V, TGF of 3.69 V‐1, Ion/Ioff ratio of 3.41 × 1013, Cgs of 3.78 × 10−16 F and fT of 1.19 × 1013 Hz, hence indicating an improved RF and DC analysis.
Sustainable refined products supply chain: A reliability assessment for demand‐side management in primary distribution processes
Authors: Wang Bohong , Zhang Haoran , Yuan Meng , Guo Zhiling , Liang Yongtu 
Published: December 2019

AbstractThe reliable operation of the primary distribution of refined products supply chains is crucial in guaranteeing the demand for retail markets. The uncertainties such as demand, production, and inventory will affect the supply chain operation. However, there lacks literature that studies the reliability of demand‐side management of refined products supply chains. This reliability assessment can help define the weak points and boost the performance of the supply chain. And it can help decision‐makers to improve the satisfaction of retail markets. In this paper, a systematic method for comprehensively assessing the reliability of refined products supply chains is proposed. At first, a mathematical programming model is developed to get the distribution plan of refined products. Then, several scenarios such as increasing demand, decreasing production, refineries disruption, and pipeline interruption relevant to the real situations of refined products supply chains are defined. Besides, indices including satisfaction rate, number of dissatisfied retail markets, refined products shortage, shortage of a single retail market, and average shortage duration are proposed to evaluate the reliability of the demand‐side management in primary distribution processes. At last, the Monte Carlo simulation is adopted for a comprehensive analysis combining all the scenarios. This analysis shows a clear picture of the influence of uncertainties. This method is applied to assess the reliability of demand‐side management of a real refined products supply chain. After analyzing different scenarios, the average probability of dissatisfaction under the reference scenario came as 1.93 × 10−4/day that means one day in around 14.2 years could have refined products shortage. This method can also help decision‐makers to assess other primary distribution of refined products supply chains.

Published: December 2019

AbstractAn annular powder‐liquid mixer is a new type of jet pump used to mix powder. This mixer is mainly used to mix fracturing fluids in oil and natural gas exploitation processes. Free from powder pellets, the mixer has characteristics, such as high mixing efficiency and great suction. The structural parameters, such as hose diameter, exit section diameter, falloff angle, divergence angle, hose length‐diameter ratio, and annular nozzle diameter, may influence this new type of mixer. By using an orthogonal experiment to optimize the structure of an annular ring‐type powder mixer and performing a comparative analysis of the results of numerical simulations, this paper finally determines the mixer's structure. According to experiments, the mixer's negative suction can reach 0.09 MPa, there are no powder pellets during the mixing process, and the mixing effect is very good.
