description: This paper develops a polyhedral approach to the design, analysis, and computation of dynamic allocation indices for scheduling binary-action (engage/rest) Markovian stochastic projects which can change state when rested (restless bandits (RBs)), based on partial conservation laws (PCLs). This extends previous work by the author [J. Niño-Mora. Restless bandits, partial conservation laws and indexability. Adv. Appl. Probab., vol. 33, 76-98, 2001], where PCLs were shown to imply optimality of index policies with a postulated structure under admissible linear objectives, and they were deployed to obtain sufficient conditions for the existence of Whittle's index and an adaptive-greedy index algorithm. The contributions include: (i) we develop the polyhedral foundation of the PCL framework, based on structural and algorithmic properties of a polytope associated with an accessible set system ($\mathcal{F}$-extended polymatroid); (ii) we present new indices for RBs, motivated by an admission control model, which extend Whittle's and have a significantly increased scope; (iii) we deploy PCLs to obtain both sufficient conditions for the existence of the new indices (PCL-indexability) and a reformulated adaptive-greedy index algorithm; (iv) we interpret PCL-indexability in terms of the economic law of diminishing marginal returns and characterize the index as an optimal marginal cost rate; (v) we carry out a PCL-indexability analysis of the motivating admission control model, which gives, under mild conditions, a new index characterization of optimal threshold policies; and (vi) we apply the latter to present new heuristic index policies for two hard queueing control problems: admission control and routing to parallel queues; and scheduling a multiclass make-to-stock queue with lost sales, both under state-dependent holding cost rates and birth-death dynamics.

description: Background: Fluorescence optical imaging (FOI) enables visualisation of inflammation in both hands in rheumatoid arthritis (RA). Objective: To investigate the usefulness of FOI in treatment monitoring under anti-TNF alpha therapy with certolizumab pegol (CZP) in patients with RA in comparison to clinical and laboratory outcome parameters. Methods: CZP-naive patients with RA were eligible for this open-label study with an observational period of 52 weeks. Disease activity was monitored by the clinical score DAS28, tender/swollen joint count (TJC-28/SJC-28) and laboratory outcomes for systemic inflammation (CRP and ESR). FOI results were analysed in three different phases (P1-3) and PrimaVistaMode (PVM) by the FOI activity score (FOIAS). Results: Twenty-eight RA patients (median age 52.5 years, 26 females, thirteen with a history of other biologic therapy) were included. DAS28 (CRP) decreased from moderate disease activity at baseline (median 4.6, IQR 1.8) to low disease activity at week (w)52 (median 2.7, IQR 2.1; p < 0.001). Statistically significant decreases could also be demonstrated for SJC-28 and TJC-28. CRP/ESR were reduced numerically from baseline to w52. FOIAS in P1 (early phase) showed a continuous decrease of enhancement during the course of treatment period: from baseline (median 1.5, IQR 9.3) over w6 (median 1.0, IQR 3.0; p= 0.069), w12 (median 0.5, IQR 3.0; p = 0.171), w24 (n = 27 , median 0.0, IQR 3.0; p = 0.004), until w52 (n= 18, median 0.0, IQR 2.8; p = 0.091), which could not be presented for FOIAS in P2, P3 and PVM. Conclusion: FOI in P1 appears to be a valuable tool for fast and easy monitoring of treatment response to certolizumab in a clinical setting.

description: Information propagation in social media depends not only on the static follower structure but also on the topic-specific user behavior. Hence novel models incorporating dynamic user behavior are needed. To this end, we propose a model for individual social media users, termed a genotype. The genotype is a per-topic summary of a user's interest, activity and susceptibility to adopt new information. We demonstrate that user genotypes remain invariant within a topic by adopting them for classification of new information spread in large-scale real networks. Furthermore, we extract topic-specific influence backbone structures based on information adoption and show that they differ significantly from the static follower network. When employed for influence prediction of new content spread, our genotype model and influence backbones enable more than $20% improvement, compared to purely structural features. We also demonstrate that knowledge of user genotypes and influence backbones allow for the design of effective strategies for latency minimization of topic-specific information spread.

description: We investigate an extended version of the Bragg reflection waveguide (BRW) with air gaps as one of the layers. This design has the potential of drastically simplifying the epitaxial structure for integrated nonlinear optical elements at the expense of more complicated structuring. This approach would afford much more flexibility for designing and varying BRW structures. Here, we discuss an extension of the established theory for BRW slabs and report our results of applying Marcatili's method for rectangular waveguides to the BRW case. With this analytic approach we can estimate the effective index of the modes orders of magnitudes faster than with full numerical techniques such as finite-difference time-domain (FDTD) or finite elements. Initial results are mixed; while phase-matched designs have been found, they currently have no significant advantage over other schemes.

description: Background: There is no international consensus on an optimal ultrasound score for monitoring of rheumatoid arthritis (RA) on patient-level yet. Our aim was to reassess the US7 score for the identification of the most frequently pathologic and responsive joint/tendon regions, to optimize it and contribute to an international consensus. Furthermore, we aimed to evaluate the impact of disease duration on the performance of the score. Methods: RA patients were assessed at baseline and after 3 and 6 months of starting/changing DMARD therapy by the US7 score in greyscale (GS) and power Doppler (PD). The frequency of pathologic joint/tendon regions and their responsiveness to therapy were analyzed by Friedman test and Cochrane-Q test respectively, including the comparison of palmar vs. dorsal regions (chi-square test). The responsiveness of different reduced scores and the amount of information retained from the original US7 score were assessed by standardized response means (SRM)/linear regression. Analyses were also performed separately for early and established RA. Results: A total of 435 patients (N = 138 early RA) were included (56.5 (SD 13.1) years old, 8.2 (9.1) years disease duration, 80% female). The dorsal wrist, palmar MCP2, extensor digitorum communis (EDC) and carpi ulnaris (ECU) tendons were most frequently affected by GS/PD synovitis/tenosynovitis (wrist: 45%/43%; MCP2: 35%/28%; EDC: 30%/11% and ECU: 25%/11%) and significantly changed within 6 months of therapy (all p <= 0.003 by GS/PD). The dorsal vs. palmar side of the wrist by GS/PD (p < 0.001) and the palmar side of the finger joints by PD (p < 0.001) were more frequently pathologic. The reduced US7 score (GS/PD: palmar MCP2, dorsal wrist, EDC and ECU, only PD: dorsal MCP2) showed therapy response (SRM 0.433) after 6 months and retained 76% of the full US7 score's information. No major differences between the groups of early and established RA could be detected. Conclusions: The wrist, MCP2, EDC, and ECU tendons were most frequently pathologic and responsive to therapy in both early and established RA and should therefore be included in a comprehensive score for monitoring RA patients on patient-level.

description: A supramolecular redox responsive nanogel (NG) with the ability to sense cancer cells and loaded with a releasing therapeutic agent was synthesized using hostguest interactions between polyethylene glycol-grafted-β-cyclodextrin and ferrocene boronic acid. Cyclic voltammetry matched with other spectroscopy and microscopy methods provided strong indications regarding host-guest interactions and formation of the NG. Moreover, the biological properties of the NG were evaluated using fluorescence silencing, confocal laser scanning microscopy, and cell toxicity assays. Nanogel with spherical core-shell architecture and 100–200 nm sized nanoparticles showed high encapsulation efficiency for doxorubicin (DOX) and luminol (LU) as therapeutic and sensing agents. High therapeutic and sensing efficiencies were manifested by complete release of DOX and dramatic quenching of LU fluorescence triggered by 0.05 mM H2O2 (as an ROS component). The NGs showed high ROS sensitivity. Taking advantage of a high loading capacity, redox sensitivity, and biocompatibility, the NGs can be used as strong theranostic systems in inflammation-associated diseases.

description: Pharmacokinetic–pharmacodynamic (PKPD) models, which describe how drug concentrations change over time and how that affects pathogen growth, have proven highly valuable in designing optimal drug treatments aimed at bacterial eradication. However, the fast rise of antimicrobial resistance calls for increased focus on an additional treatment optimization criterion: avoidance of resistance evolution. We demonstrate here how coupling PKPD and population genetics models can be used to determine treatment regimens that minimize the potential for antimicrobial resistance evolution. Importantly, the resulting modelling framework enables the assessment of resistance evolution in response to dynamic selection pressures, including changes in antimicrobial concentration and the emergence of adaptive phenotypes. Using antibiotics and antimicrobial peptides as an example, we discuss the empirical evidence and intuition behind individual model parameters. We further suggest several extensions of this framework that allow a more comprehensive and realistic prediction of bacterial escape from antimicrobials through various phenotypic and genetic mechanisms.

description: Several projects around the planet aim at building a new generation of superconducting magnets for particle accelerators, relying on Nb3Sn conductor, with peak fields in the range of 10-15 T. In this paper we give an overview of the main challenges for protecting this new generation of magnets. The cases of isolated short magnets, in which the energy can be extracted on an external dump resistor, and chain of long magnets, which have to absorb their stored energy and have to rely on quench heaters, are discussed. We show that this new generation of magnets can pose special challenges, related to both the large current density and to the energy densities.

Towards Formative Assessment: Exploring English Teachers’ Conceptions And Practices Of Assessment In Indonesia

Year: 2020
Subjects: Uncategorized

description: Formative assessment has been considered a substantial element of curriculum reform across the world, and this is the case through the implementation of the new 2013 curriculum (K13) in Indonesia. This interpretivist mixed-methods study was developed to understand more about the key developments in teachers’ conceptions and practices of assessment; how teachers construe the influence of the K13 assessment policy on their assessment thinking and practices; the ranges of influence that teachers consider important for shaping their assessment practices and thinking; and the embedding of Assessment for Learning (AfL) strategies in classroom. Sociocultural theory and Normalisation Process Theory were employed to analyse and interpret the data.Teacher assessment conceptions embrace values, purposes, and understanding, and are marked strongly by improvement and accountability orientations, and an implicit, less-developed conceptual and practical understanding of assessment. These conceptions were reflected in teachers’ assessment practices, which encompassed learning, grading, and promotion of learner agency, but the former two were more frequently emphasized. Attempts to integrate the K13 reforms had been initiated, but often lacked substantive features. Internal influences associated with students, teachers, and school resources/support affected teachers’ selection of assessment practices. The lack of assessment literacy, motivation and teaching commitment made the reform implementation difficult to carry out, within the inadequate learning resources. Externally, the government and parents lacked on-going monitoring and support.The findings revealed some powerful influences on teachers’ conceptions, understanding and practices, suggesting that the integration of innovations should start from improving teachers’ understanding, and then move on to inform and adjust teachers’ perceptions about the reforms. This highlights the need for accountable professional development to improve teachers’ pedagogy and assessment literacy and the importance of a clear vision, on the part of designers and implementers, how the reforms are designed, implemented and evaluated to ensure effective embedding.

description: An Autographed Letter Signed (ALS) by “W.P. Frith”, to Tom Taylor, identifying characters in his series “The Race for Wealth”, and discussing Taylor’s recent pamphlet. Tom Taylor (1817-1880), was a critic, dramatist and editor of Punch. William Powell Frith (1819-1909) was a painter of historical and genre works, including large canvases such as Derby Day (1858). “The Race for Wealth” comprises five paintings, all based around a fictional central character, a corrupt financier called The Spider, and all dealing with the theme of reckless financial speculation. Inspired by characters found in the novels of Charles Dickens and Anthony Trollope, The Spider persuades his victims to invest in dubious schemes. Often compared with Hogarth’s “The Rake’s Progress,” “The Race for Wealth” portrays The Spider’s initial success, his unmasking, his trial, and ends with his imprisonment.

Both interface corrugation and periodical change in the optical conductivity are considered. Explicit expressions for reflection, transmission, absorption and transformation coefficients in arbitrary diffraction orders are presented. The dispersion relation and decay rates for graphene plasmons of the grating are found. Simple analytical expressions for the value of the band gap in the vicinity of the first Brillouin zone edge is derived. The optimal amplitude and wavelength, guaranteeing the best matching of the incident light with graphene plasmons are found for the conductivity grating. The analytical results are in a good agreement with first-principle numeric simulations.

description: We present methods that can provide an exponential savings in the resources required to perform dynamic parameter estimation using quantum systems. The key idea is to merge classical compressive sensing techniques with quantum control methods to efficiently estimate time-dependent parameters in the system Hamiltonian. We show that incoherent measurement bases and, more generally, suitable random measurement matrices can be created by performing simple control sequences on the quantum system. Since random measurement matrices satisfying the restricted isometry property can be used to reconstruct any sparse signal in an efficient manner, and many physical processes are approximately sparse in some basis, these methods can potentially be useful in a variety of applications such as quantum sensing and magnetometry. We illustrate the theoretical results throughout the presentation with various practically relevant numerical examples.

description: Background: Since establishing the first poison control centers (PCCs), there is a still ongoing debate regarding their relevance and financing. The present study aims to analyze whether a regional PCC can reduce the economic burden associated with utilization of health care structures due to low-risk poison exposures on the German health care system. Methods: A decision-tree based cost-benefit analysis comparing a situation utilizing PCC consultation versus a hypothetical situation without PCC consultation for low-risk poison exposures from the German health care system's perspective was conducted. The model inputs were obtained by a representative telephone survey of lay callers supplemented by empirical PCC and literature data. A probabilistic and deterministic sensitivity analysis with varying input variables was performed to prove the robustness of the findings. Results: In the underlying telephone survey, data of 378 lay callers could be considered and included in the decision tree model. As a result, the mean costs for handling one low-risk poison exposure case were euro 41.99 utilizing PCC consultation compared to euro 145.92 without PCC consultation, indicating a cost-benefit ratio of 3.48 for the existence of the PCC. The sensitivity analysis proved that the outcome of the decision analysis does not change significantly with varying inputs. Conclusion: The existence of PCCs relieve the burden on other health care providers and reduce health care costs to a relevant extent. Therefore, PCCs should be considered as an important supporting structure of the German health care system.

They served as oil or scent containers, like aryballoi and alabastra. This paper presents an unusual piece which throws some light on the origin and the significance of the type. The design on his back depicts the carapace of a scarab-beetle. The origin of this hybrid figure must be sought in Egyptian art, where the images of scarabs and dwarfs can blend. Was the type was just "meant to be amusing" or did it inherit the apotropaic qualities of Egyptian models?

description: A many-server heavy-traffic FCLT is proved for the $G_t/M/s_t+\mathit {GI}$ queueing model, having time-varying arrival rate and staffing, a general arrival process satisfying a FCLT, exponential service times and customer abandonment according to a general probability distribution. The FCLT provides theoretical support for the approximating deterministic fluid model the authors analyzed in a previous paper and a refined Gaussian process approximation, using variance formulas given here. The model is assumed to alternate between underloaded and overloaded intervals, with critical loading only at the isolated switching points. The proof is based on a recursive analysis of the system over these successive intervals, drawing heavily on previous results for infinite-server models. The FCLT requires careful treatment of the initial conditions for each interval.

A significant increase of HAI was reported by US hospitals when comparing incidence rates from 2019 and 2020. The objective of this study was to investigate the development of the most relevant device-associated HAI in German ICUs during the year 2020 as compared to 2019. Methods: We utilized the data of the ICU component of the German National Reference Center for Surveillance of Nosocomial Infections (KISS = Krankenhaus-Infektions-Surveillance-System) for the period 2019-2020. We focused on central line-associated bloodstream infections (CLABSI), catheter-associated urinary tract infections (CAUTI), ventilator-associated lower respiratory infections (VALRTI) and bloodstream infections associated with the use of Extracorporeal-Life-Support-Systems (ECLSABSI). Device use was defined as the number device days per 100 patient days; device-associated infection rates as the number of device-associated infections per 1000 device days. To compare the pooled means between the years and quarters we calculated rate ratios of device-associated infection rates with 95% confidence intervals by Poisson regression models. Results: The number of participating ICUs in the surveillance system decreased from 982 in 2019 to 921 in 2020 (6.2%). Device utilization rates increased significantly for central lines and ventilator use. VALRTI rates and CAUTI rates decreased in 2020 compared with 2019, however, no increase was shown for CLABSI or ECLSABSI. This result was also confirmed when the corresponding quarters per year were analyzed. Conclusions: The lack of an increase in device-associated healthcare associated infections (HAI) in German ICUs may be due to the lower overall incidence of COVID-19 cases in Germany in 2020 compared with US, to a very high availability of ICU beds per 100,000 inhabitants compared with many other countries, and a change in the ICU patient mix due to numerous elective procedures that were postponed during the first two waves. The primary reason seems to be that only 7% of all ICU patients in Germany in 2020 were COVID-19 patients.
title: He’s like, “My Nan loves that naan bread” quotative be+like and mimetic performance among migrants to St. John’s NL

description: This thesis examines quotative verb use and mimetic performance among migrants to St. Johns, Newfoundland. The first part examines the variation and distribution of quotative verbs among this community, implements variable rule analysis and delves into which grammatical and social constraints condition the choice of quotative verbs by these speakers. The second part investigates the properties of mimetic speech and explores how these individuals create voices using the acoustic properties of vowels. These topics are examined through the lens of social network theory (Milroy 1987) and performance speech. I propose a framework of sociolinguistic comfort that incorporates these concepts to account for the patterns of quotative and mimetic performance. As our world grows ever more global, understanding the ways migrant speakers learn to perform identity, incorporate highly regionalized features, and yet remain connected to their adopted community is essential.

description: Background: Rational use of antibiotics (AB) and infection prevention and control (IPC) are key measures for reducing antimicrobial resistance (AMR) in healthcare. Nonetheless, transferring evidence into clinical practice in emergency medicine has proven difficult. The extent to which structural requirements for implementing AMR control exist in German emergency departments (ED) was determined in a survey. Methods: Aspects of antimicrobial stewardship (AMS) and IPC implementation were surveyed within the German Association for Emergency Medicine (Deutsche Gesellschaft interdisziplinare Notfall- und Akutmedizin e.V, DGINA) in 2018. Data were collected using an anonymous online questionnaire on ED characteristics, ED-based-link personnel for IPC and AMS, education and training, process monitoring and specific requirements for AMS and IPC as availability of AMR data and alcohol-based hand rub (AHR) consumption data. Data were analysed descriptively. Results: 66 EDs with in median [interquartile range (IQR)] of 30,900 [23,000; 40,000] patient visits participated in the survey. EDs' healthcare worker (HCW) received regular training on hand hygiene (HH) in 67% and on AMS in 20% of EDs. Surveillance of AHR consumption was performed by 73% EDs, surveillance of AB consumption by 64%. Regular audits on HH were performed in 39%. Training and audit activities, showed no significant variations according to EDs' organizational characteristics. HCWs received immediate feedback of HH performance in 29%, in 23% a regular structured feedback of HH was provided. ED-based physicians with (1) specific IPC responsibilities and training were available in 61%, with (2) AMS training and responsibility in 15%. 83% had ED based IPC link nurses with precise ICP responsibilities in place. Essentially resistance data existed at the hospital level (74%) rather than at ED- or regional level (15% and 14% respectively). Conclusions: Management of AMR varies in German EDs, especially in accordance to hospital size and level of emergency care. IPC seems to receive more attention than AMS. Our data indicate the need for more implementation of regular IPC and AMS training in connection with monitoring and feedback in German EDs.

description: In this paper we prove the following topological classification result for flows on real projective space induced by linear flows on Euclidean space: Two flows on the projective space P(V) of a finite-dimensional real vector space V, induced by endomorphisms A and B of V, are topologically conjugate if and only if the Jordan structures of A and B coincide except for the real parts of the eigenvalues whose values may differ but whose order and multiplicities must agree. Our proof is mainly based on ideas of Kuiper who considered the discrete-time analogue of this classification problem. We also correct a mistake in Kuiper's proof.

description: The tides are a major driver of global oceanic mixing. While global tidal elevations are very well observed by satellite altimetry, the global tidal transports are much less well known. For twenty years, magnetic signals induced by the ocean tides have been detectable in satellite magnetometer observations, such as Swarm or CHAMP. Here, we demonstrate how satellite magnetometer observations can be used to directly derive global ocean tidal transports. As an advantage over other tidal transport estimates, our tidal estimates base on very few and very loose constraints from numerical forward models.

description: Contemporary security interventions in Africa are characterized by an increasing pluralization of external actors, bringing with them new security rationalities, practices, and technologies, sometimes with profound influences on local security dynamics. While studies have focused empirically on East and South Africa, this article explores the roles of the United Arab Emirates (UAE) and Turkey in the Sahel region of West Africa. To make sense of their engagement, we develop the notion of ‘transnational security entanglements’ by bringing the literature on (in)security assemblages into productive dialogue with scholarship on transnational entanglements in the fields of global history and law. Both literatures depart from relational ontologies, eschew methodological nationalism, and emphasize the interplay between the human and the non-human in the making of the social world. At the same time, we argue, the focus on entanglements adds a specific analytic of South–South connections and transregional circulations to extant scholarship on (in)security assemblages. To illustrate the importance of these transregional connections beyond the North Atlantic, we draw on interviews and media reports about the myriad ways in which connections between the UAE and Turkey with various actors in the Sahel shape current transformations of political orders in the region.

description: The LHAASO (Large High Altitude Air Shower Observatory) experiment is proposed for very high energy gamma ray source survey, in which the WCDA (Water Cherenkov Detector Array) is the one of the major components. In the WCDA, a total of 3600 PMTs are placed under water in four ponds, each with a size of 150 m x 150 m. Precise time and charge measurement is required for the PMT signals, over a large signal amplitude range from single P.E. (photo electron) to 4000 P.E. To fulfill the high requirement of signal measurement in so many front end nodes scattered in a large area, special techniques are developed, such as multiple gain readout, hybrid transmission of clocks, commands, and data, precise clock phase alignment, and new trigger electronics. We present the readout electronics architecture for the WCDA and several prototype modules, which are now under test in the laboratory.

description: As accelerator magnets see the increase of their magnetic field and stored energy, quench protection becomes a critical part of the magnet design. Due to the complexity of the quench phenomenon interweaving magnetic, electrical and thermal analysis, the use of numerical codes is a key component of the process. In that respect, we propose here a review of several tools commonly used in the magnet design community.

description: Section 1: Literature ReviewLiterature on antisocial attitudes and violence in young people in a forensic setting was reviewed. Seven studies were reviewed, five of which supported the view that violent young people are more likely to hold antisocial attitudes compared to their non-violent peers. Homogeneous and heterogeneous attitudes are explored. A critique of the review is provided including limitations, implications and suggestions for future research.Section 2: Research ReportComparisons of the experience of emotions using the Strengths and Difficulties Questionnaire (SDQ) and antisocial cognitions using the How I Think Questionnaire (HIT) between violent (n = 74) and non-violent (n = 22) young people within a secure training centre were explored. Quantitative analyses indicated that the violent group did not experience significantly more emotions or cognitive distortions than the non-violent group. Results are discussed in relation to previous research. Clinical implications are considered, as well as possibilities for future research in light of the research limitations.Section 3: Service EvaluationAn evaluation of the effectiveness of the Forward Thinking® ‘What Got Me Here?’ group intervention at a secure training centre for young people with a sample of N = 18. Non-parametric analysis of pre and post intervention outcome changes on the University Rhode Island Change Assessment Scale (URICA), and the What Got Me Here Facilitator Assessment of Participant indicated significant improvements on overall readiness to change, contemplation and action indices on the URICA, and on all indices in the facilitator assessment. Recommendations, future opportunities as well as a critique of the study is provided.Section 4: Critical AppraisalA critique of the research methodology and limitations, and setting and role challenges, is discussed. A reflection of personal and professional learning is explored.
