Learning of assessment in teacher education: the role of epistemic beliefs

ABSTRACT Objective Being skilled in the development and use of assessments is crucial if teachers are to know whether their students are meeting learning objectives. Unfortunately, many preservice teachers hold beliefs at odds with views that are adaptive for the promotion of learning. The purpose of this mixed-methods study was to explore the relationships between epistemic beliefs and preservice teachers’ understanding of foundational concepts of assessment. Method Participants were 282 undergraduate students enrolled in an educational psychology course. Multiple regression was used to examine these relationships followed by a deductive analysis of field journal entries. Results Results revealed a relationship between epistemic beliefs and understanding of assessment. Those with beliefs in knowledge as more fluid and evolving made more connections between the course and their field experience and demonstrated greater understanding of foundational concepts. Conclusions Our findings suggest that teacher education programs should be structured in ways to promote these beliefs. Such beliefs may result in more effective teaching and assessment practices more congruent with the promotion of meaningful learning amongst the next generation of students. KEY POINTS What is already known about this topic: (1) Epistemic beliefs play a role in what is learned. (2) Epistemic beliefs are associated with metacognitive strategy use, reasoning skills, critical thinking skills, creativity, and motivation. (3) Assessment practices can shape students’ beliefs about the nature of knowledge. What this study adds: (1) A mixed-methods examination of epistemic beliefs in teacher education. (2) Quantitative results reveal epistemic beliefs significantly contribute to the variance in preservice teachers learning of foundation concepts of assessment. (3) Qualitative results reveal students with more epistemic beliefs are more likely to make connections between coursework and field experiences.
Depth-Bounded Inference for Nonterminating Prologs

In this paper, we study the completeness of the depth-bounded resolution, which is an SLD-resolution that prunes infinite derivations using the depth-bound. We introduce a class of definite programs with local variables, called linearly covering programs, and prove the completeness of the depth-bounded resolution for the class with respect to the CWA of Reiter.
RG flow of transport quantities

The RG flow equation of various transport quantities are studied in arbitrary space–time dimensions, in the fixed as well as fluctuating background geometry both for the Maxwellian and DBI type of actions. The regularity condition on the flow equation of the conductivity at the horizon for the DBI action reproduces naturally the leading order result of Hartnoll et al. [J. High Energy Phys. 04, 120 (2010)]. Motivated by the result of van der Marel et al. [Science 425, 271 (2003], we studied, analytically, the conductivity versus frequency plane by dividing it into three distinct parts: ω T and ω ≫ T. In order to compare, we choose (3+1)-dimensional bulk space–time for the computation of the conductivity. In the ω T range and staying away from the horizon, for the DBI action with unit dynamical exponent, nonzero magnetic field and charge density, the conductivity goes as ω-2/3, whereas the phase of the conductivity, goes as, arctan(Im σxx/Re σxx) = π/6 and arctan(Im σxy/Re σxy) = -π/3. There exists a universal quantity at the horizon that is the phase angle of conductivity, which either vanishes or an integral multiple of π. Furthermore, we calculate the temperature dependence to the thermoelectric and the thermal conductivity at the horizon. The charge diffusion constant for the DBI action is studied.
Modeling semiflexible polymer networks

This is an overview of theoretical approaches to semiflexible polymers and their networks. Such semiflexible polymers have large bending rigidities that can compete with the entropic tendency of a chain to crumple up into a random coil. Many studies on semiflexible polymers and their assemblies have been motivated by their importance in biology. Indeed, cross-linked networks of semiflexible polymers form a major structural component of tissue and living cells. Reconstituted networks of such biopolymers have emerged as a new class of biological soft matter systems with remarkable material properties, which have spurred many of the theoretical developments discussed here. Starting from the mechanics and dynamics of individual semiflexible polymers, the physics of semiflexible bundles, entangled solutions, and disordered cross-linked networks are reviewed. Finally, recent developments on marginally stable fibrous networks, which exhibit critical behavior similar to other marginal systems such as jammed soft matter, are discussed.
Result of a year-long animal survey in a state-owned forest farm in Beijing, China

Abstract Background Artificial forest can have great potential in serving as habitat to wildlife, depending on different management methods. As the state-owned forest farms now play a new role in ecological conservation in China, the biological richness of this kind of land-use type is understudied. Once owned by a mining company, a largest state-owned forest farm, Jingxi Forest Farm, has been reformed to be a state-owned forest farm with the purpose of conservation since 2017. Although this 116.4 km2 forest farm holds a near-healthy montaine ecosystem very representative in North China, a large proportion of artificial coniferous forest in the forest farm has been proven to hold less biodiversity than natural vegetation. This situation, however, provides a great opportunity for ecological restoration and biodiversity conservation. Therefore, from November 2019 to December 2020, we conducted a set of biodiversity surveys, whose results will serve as a baseline for further restoration and conservation. New information Here, we report the result of a multi-taxa fauna diversity survey conducted in Jingxi Forest Farm mainly in year 2020 with explicit spatial information. It is the first survey of its kind conducted in this area, revealing a total of 19 species of mammals, 86 birds, four reptiles, two amphibians and one fish species, as well as 101 species of insects. Four species of mammals are identified as data-poor species as they have less than 100 occurrence records with coordination in the GBIF database. One species of insect, representing one new provincial record genus of Beijing, is reported.
An Online Condition Monitoring Method for IGBT Gate Oxide Degradation Based on the Gate Current in Miller Plateau

The reliability of power converters is one of the important issues due to the widespread applications of power electronics in many industrial fields. Accordingly, condition monitoring (CM) methods for the assessment of the health of the converter components are considered a practical topic for researchers and experts in the field. This article aims to propose a CM method for insulated gate bipolar transistor (IGBT) gate oxide degradation. The proposed CM is based on the gate–emitter current during the turning-on process. It is shown that in the degradation process, the gate current peak value majorly increases. The proposed CM method captures this peak value and uses it as a degradation indicator. The proposed method is simple and analogous and can be used easily for online health assessment of the IGBTs under operation. It can be integrated into the driver module to assess the gate oxide degradation of the device. The functionality of the proposed method is evaluated using experimental prototyping. The target devices are a 1200-V, 40-A trench-gate field-stop IGBT and a 600-V and 60-A planner gate punch-through discrete IGBT. The achieved results show the validity and acceptable performance of the proposed CM for detecting the gate oxide degradation of the device.
QUANTIZATION OF DISSIPATIVE SYSTEMS WITH SECOND-ORDER LAGRANGIAN

This paper examined dissipative systems with second order Lagrangian in the framework of the Hamilton-Jacobi method. The principal function is determined using the method of separation of variables in the same manner as for regular time-independent Lagrangian. The equations of motions are obtained from the action function. By finding the action function, the wave function can be constructed and the quantization has been carried out using the WKB approximation. One example is given to illustrate our formalism.
New representations for the conditional approach to multivariate extremes

The conditional approach to multivariate extremes concerns the characterization of the limiting distribution of appropriately normalized random vectors given that at least one of their components is large. The statistical methods for the conditional approach are based on a parametric family of location and scale norming functions proposed by Heffernan and Tawn (2004). Recently, inverted max-stable processes have been proposed as an important new class for spatial extremes covering asymptotic independence in contrast to max-stable processes which are asymptotically dependent. We study a broad range of inverted maxstable processes and present examples where the normalizations required for non-degenerate conditional limit laws do not belong to the parametric family identified by Heffernan and Tawn. Despite such differences at an asymptotic level, we show that at practical levels, the model of Heffernan and Tawn approximates well the true conditional distributions.
Statistical study of emerging flux regions and the response of the upper atmosphere

We statistically study the properties of emerging flux regions (EFRs) and response of the upper solar atmosphere to the flux emergence using data from the Helioseismic and Magnetic Imager and the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory. Parameters including total emerged flux, flux growth rate, maximum area, duration of the emergence and separation speed of the opposite polarities are adopted to delineate the properties of EFRs. The response of the upper atmosphere is addressed by the response of the atmosphere at different wavelengths (and thus at different temperatures). According to our results, the total emerged fluxes are in the range of (0.44−11.2)×1019 Mx while the maximum area ranges from 17 to 182 arcsec2. The durations of the emergence are between 1 and 12 h, which are positively correlated to both the total emerged flux and the maximum area. The maximum distances between the opposite polarities are 7–25 arcsec and are also positively correlated to the duration. The separation speeds are from 0.05 to 1.08 km s−1, negatively correlated to the duration. The derived flux growth rates are (0.1−1.3)×1019 Mx h−1, which are positively correlated to the total emerging flux. The upper atmosphere first responds to the flux emergence in the 1600Å chromospheric line, and then tens to hundreds of seconds later, in coronal lines, such as the 171Å (T = 105.8 K) and 211Å (T = 106.3 K) lines almost simultaneously, suggesting the successive heating of the atmosphere from the chromosphere to the corona.
Millennial‐scale oscillations and an environmental regime shift around the Middle to Late Holocene transition in the North Atlantic region based on a multiproxy record from Isfjorden, West Spitsbergen

Palynological and sedimentological analyses were performed on the sediment core HH16‐1205‐GC retrieved from the central Isfjorden, West Spitsbergen. The sequence, which spans the last 7000 years, revealed an overall cooling trend with an important climate shift between 4.4 and 3.8 cal. ka BP, in addition to millennial‐scale oscillations. Sea‐surface reconstruction from dinocyst assemblages indicates a decrease in summer sea‐surface temperature, from 2.5 to 1.5 °C, and primary productivity, from 750 to 650 gC m−2 a−1 over the last 7000 years. From around 6.8 to 5.8 cal. ka BP, the sedimentological and palynological data suggest a predominant sediment supply from the inner part of the fjord, ice rafting, dense sea ice cover, strongly stratified water masses and high primary productivity. The interval from 4.4 to 3.8 cal. ka BP is marked by a layer of coarser material and a significant decrease in the grain‐size mode. Our geochemical data show large‐amplitude fluctuations after 2.0 cal. ka BP, while an increase in the dinocysts Impagidinium pallidum and Spiniferites elongatus from 2.0 to 1.2 cal. ka BP suggests enhanced Atlantic Water inflow. The dinocyst‐based reconstructions also reveal large‐amplitude millennial fluctuations in sea ice cover, summer sea‐surface temperature and salinity. Wavelet analysis and cross‐wavelet analysis on K/Ti ratio coupled with sea‐ice estimates confirm a strong signal with a periodicity of 1200–1500 years.
A survey of ECH microwave technology

A survey is presented of the microwave transmission system and antenna technology that has been developed for electron cyclotron heating (ECH) experiments using gyrotron and FEL sources. The development of these sources make the bulk heating of a fusion reactor a realistic possibility. Utilization of these sources, with their high unit output power and higher order output modes, has required the development of novel transmission and launching systems. Many examples of such systems applied to tokamaks are given.
On the Fourier-Laplace representation of analytic functions in tube domains

Let $C$ denote an acute convex open cone in $\mathbb{R}^n$ with an apex at the origin and let $T(C) = \mathbb{R}^n + iC$ be the corresponding tube in $\mathbb{C}^n$. We define a space of holomorphic functions $f(z)$ of exponential type in $T(C)$ which have boundary values $f_0(x)$, as $y\rightarrow 0, y\in C$, satisfying some inequality. We obtain Fourier- Laplace integral representation of these functions. As a consequence a weighted version of the edge of the wedge theorem and Fourier-Laplace representation of entire functions of exponential type (with more general growth characteristics than in [2]) are obtained.
The importance of raising the intercultural sensitivity of university students

This paper describes the theoretical background of the planning and implementation process for an intercultural sensitivity training programme targeting foreign students based on the experience of a previous intercultural projects (Furcsa, 2009; Szaszkó, 2018). At Eszterházy Károly University (EKU) (Eger, Hungary), foreign students come from different countries to study in various fields and participate in a programme tailored toward raising intercultural awareness each semester. The authors of the present article actively contributed to the design and implementation of this special training programme developed for the incoming students at EKU. The main objectives of this intercultural sensitivity-raising programme are to gain a deeper knowledge and understanding of various cultures, focus on the issues of biases, stereotypes, discrimination, acculturation, problem-solving, skills development, and team building, all aspects that comprise focal points of this paper.
The Clebsch System

The Clebsch system is one of the few classical examples of rigid bodies whose equations of motion are known to be integrable in the sense of Liouville. The explicit solution of its equations of motion, however, is particularly hard, and it has defeated many attempts in the past. In this paper we present a novel and rather detailed study of these equations of motion. Our approach is based on an improved version of the method originally used, in 1889, by Sophia Kowalewski to solve the equations of motion of the top bearing her name. We improve her method in two important points, and we clarify that it concerns a class of dynamical systems which is wider than the class of Hamiltonian systems which are integrable in the sense of Liouville. We use the improved version of the method by Kowalewski to prove two results. First, without using the Hamiltonian structure of the Clebsch system, we show that the integration of the equations of motion may be achieved by computing four Abelian integrals. Next, taking into account its Hamiltonian structure, we show that two quadratures are sufficient to compute a complete integral of its Hamilton-Jacobi equation. In this way, the process of solution of the equations of motion of the Clebsch system is clarified both from the standpoint of Abel and from the standpoint of Jacobi.
Hybrid CNN-Transformer Features for Visual Place Recognition

Visual place recognition is a challenging problem in robotics and autonomous systems because the scene undergoes appearance and viewpoint changes in a changing world. Existing state-of-the-art methods heavily rely on CNN-based architectures. However, CNN cannot effectively model image spatial structure information due to the inherent locality. To address this issue, this paper proposes a novel Transformer-based place recognition method to combine local details, spatial context, and semantic information for image feature embedding. Firstly, to overcome the inherent locality of the convolutional neural network (CNN), a hybrid CNN-Transformer feature extraction network is introduced. The network utilizes the feature pyramid based on CNN to obtain the detailed visual understanding, while using the vision Transformer to model image contextual information and aggregate task-related features dynamically. Specifically, the multi-level output tokens from the Transformer are fed into a single Transformer encoder block to fuse multi-scale spatial information. Secondly, to acquire the multi-scale semantic information, a global semantic NetVLAD aggregation strategy is constructed. This strategy employs semantic enhanced NetVLAD, imposing prior knowledge on the terms of the Vector of Locally Aggregated Descriptors (VLAD), to aggregate multi-level token maps, and further concatenates the multi-level semantic features globally. Finally, to alleviate the disadvantage that the fixed margin of triplet loss leads to the suboptimal convergence, an adaptive triplet loss with dynamic margin is proposed. Extensive experiments on public datasets show that the learned features are robust to appearance and viewpoint changes and achieve promising performance compared to state-of-the-arts.
Decoupling Theorems

Decoupling theorems have proven useful in various applications in the area of quantum information theory. This thesis builds upon preceding work by Frédéric Dupuis [5], where a general decoupling theorem is obtained and its implications for quantum coding theory are studied. At first we generalize this theorem to the case where the average is taken over an approximate unitary 2-design. The second part of this thesis tackles the question whether or not it is possible to decorrelate CQ-states with classical operations. We obtain results similar to the pivotal Leftover Hash Lemma. Finally we analyze the decoupling power of permutation operators in a fully quantum context and show a general procedure that yields decoupling theorems with permutations.
A study of the relationship between online movie reviews and the intention to watch the movie

Abstract Aim/purpose – This study explores how the content feature and source of eWOM affect people’s intentions and further analyses the effectiveness of eWOM on people’s intention to watch movies. Design/methodology/approach – The study considers two dimensions of movie reviews, including the source (anonymous or acquaintance) and the content feature (concrete or abstract), adopts a 2x2 between-subject design, and then analyzes online questionnaires (N = 313) via statistics analysis methods. Findings – The findings showed that if the source is from an acquaintance and the content feature is concrete, then people will have the highest intention to watch the movie. In addition, the acting skills of the cast and the love of the movie genre also enhance the positive influence on the viewer’s experience. Research implications/limitations – The respondents were selected only in Taiwan so this paper do not explain any differences among different countries. For example, cultural differences exist between the West and the East in the content feature of eWOM. Originality/value/contribution – If a type of genre is greatly accepted by the audience and generates huge box-office revenue, then producers and movie companies might keep making movies in these kinds of genre to secure profits. Therefore, box-office movies will usually fall into these certain types of genres, and there will be an abundance of them released in the near future.
A Single-Loop Third-Order 10-MHz BW Source-Follower-Integrator Based Discrete-Time Delta-Sigma ADC

This brief presents a single-loop third-order discrete-time delta-sigma (<inline-formula> <tex-math notation="LaTeX">$ {\Delta } {\Sigma }$ </tex-math></inline-formula>) analog-to-digital converter (ADC). The proposed <inline-formula> <tex-math notation="LaTeX">$ {\Delta } {\Sigma }$ </tex-math></inline-formula> ADC employs source-follower (SF)-based open-loop switched-capacitor (SC) integrators to achieve high-speed operation with efficient power consumption. A modified feed-forward topology is proposed to improve the linearity of the modulator using the SF-based integrators. An interpolating 4-bit flash quantizer with an embedded data weighted averaging (DWA) function is employed to address the nonlinearity of the feedback digital-to-analog converter (DAC) for high speed operation. The prototype ADC implemented in a 65nm CMOS technology achieves 75.4-dB dynamic range (DR) and 73.3-dB peak signal-to-noise-and-distortion ratio (SNDR) over 10-MHz bandwidth with an oversampling ratio (OSR) of 16. The power consumption of the modulator is 13.3-mW from a 1.1-V supply, resulting in the Walden and Schreier figure-of-merits (FoMW and FoMS) of 174-fJ/conversion-step and 164-dB, respectively.
Renormalization group analysis of thermal transport in the disordered Fermi liquid

We present a detailed study of thermal transport in the disordered Fermi liquid with short-range interactions. At temperatures smaller than the impurity scattering rate, i.e., in the diffusive regime, thermal conductivity acquires nonanalytic quantum corrections. When these quantum corrections become large at low temperatures, the calculation of thermal conductivity demands a theoretical approach that treats disorder and interactions on an equal footing. In this paper, we develop such an approach by merging Luttinger's idea of using gravitational potentials for the analysis of thermal phenomena with a renormalization group calculation based on the Keldysh nonlinear sigma model. The gravitational potentials are introduced in the action as auxiliary sources that couple to the heat density. These sources are a convenient tool for generating expressions for the heat density and its correlation function from the partition function. Already in the absence of the gravitational potentials, the nonlinear sigma model contains several temperature-dependent renormalization group charges. When the gravitational potentials are introduced into the model, they acquire an independent renormalization group flow. We show that this flow preserves the phenomenological form of the correlation function, reflecting its relation to the specific heat and the constraints imposed by energy conservation. The main result of our analysis is that the Wiedemann-Franz law holds down to the lowest temperatures even in the presence of disorder and interactions and despite the quantum corrections that arise for both the electric and thermal conductivities.
