How are fashion merchandising curricula designed in the digital age? – Cross-cultural case study from the TPACK perspective

ABSTRACT This study investigated what and how the curricula in fashion merchandising are being offered in the United States and China in the context of digital transformation and possible differences in curricula development due to cultural and educational policy differences. The study was grounded in technological pedagogical and content knowledge (TPACK) and cultural dimension theories. Two academic programmes and eight courses were reviewed using the qualitative research method of the case study. The data were coded, classified, and analysed using MAXQDA, incorporating quantitative and qualitative data interpretations. The results revealed diverse ways for the instructors to incorporate TPACK-based curricula design approaches and highlighted the differences in curricula development between the U.S. and China programmes. The study findings offered in-depth views of the significance of TPACK on curricula development strategies and the potential challenges that educators face in meeting the industry's needs.

Trace anomalies and the graviton-dilaton amplitude

Abstract We consider 3+1 dimensional Quantum Field Theories (QFTs) coupled to the dilaton and the graviton. We show that the graviton-dilaton scattering amplitude receives a universal contribution which is helicity flipping and is proportional to ∆c − ∆a along any RG flow, where ∆c and ∆a are the differences of the UV and IR c- and a-trace anomalies respectively. This allows us to relate ∆c − ∆a to spinning massive states in the spectrum of the QFT. We test our predictions in two simple examples: in the theory of a massive free scalar and in the theory of a massive Dirac fermion (a more complicated example is provided in a companion paper [1]). We discuss possible applications.

The Characterization of Female Protagonists from the Perspective of Hofstede’s Cultural Dimension Theory: A Case Study of the Hunger Games Series

The female protagonist Katniss portrayed in the "Hunger Games" film series breaks free from the constraints of mainstream films on female protagonist images. Such a young woman can make brave choices as the protagonist in a tyrannical and chaotic world full of oppression and slaughter, not relying on those men and igniting a revolutionary wave. This is extremely rare in mainstream commercial films. In this paper, text analysis and comparative analysis will be used as the main research methods. First of all, with the help of Hofstede’s theory of cultural dimensions, the Hunger Games series of films is carefully analyzed, the construction process of Katniss’s image and his personality characteristics are deeply explored, and an attempt is made to bring a new interpretation to the audience. The purposes of this study are to draw attention to how important Katniss’s role has been in subverting conventional gender norms in movies and to provide some references for future studies.

3d Carrollian Chern-Simons theory & 2d Yang-Mills

Abstract With the goal of building a concrete co-dimension one holographically dual field theory for four dimensional asymptotically flat spacetimes (4d AFS) as a limit of AdS4/CFT3, we begin an investigation of 3d Chern-Simons matter (CSM) theories in the Carroll regime. We perform a Carroll (speed of light c → 0) expansion of the relativistic Chern-Simons action coupled to a massless scalar and obtain Carrollian CSM theories, which we show are invariant under the infinite dimensional 3d conformal Carroll or 4d Bondi-van der Burg-Metzner-Sachs (BMS4) symmetries, thus making them putative duals for 4d AFS. Concentrating on the leading-order electric Carroll CSM theory, we perform a null reduction of the 3d theory. Null reduction is a procedure to obtain non-relativistic theories from a higher dimensional relativistic theory. Curiously, null reduction of a Carrollian theory yields a relativistic lower-dimensional theory. We work with SU(N) × SU(M) CS theory coupled to bi-fundamental matter and show that when N = M, we obtain (rather surprisingly) a 2d Euclidean Yang-Mills theory after null reduction. We also comment on the reduction when N ≠ M and possible connections of the null-reduced Carroll theory to a candidate 2d Celestial CFT.

Some lower dimensional quantum field theories reduced from Chern-Simons gauge theories

We study symmetry reductions in the context of Euclidean Chern-Simons gauge theories to obtain lower dimensional field theories. Symmetry reduction in certain gauge theories is a common tool for obtaining explicit soliton solutions. Although pure Chern-Simons theories do not admit solitonic solutions, symmetry reduction still leads to interesting results. We establish relations at the semiclassical regime between pure Chern-Simons theories on S3 and the reduced quantum field theories, based on actions obtained by the symmetry reduction of the Chern-Simons action, spherical symmetry being the prominent one. We also discuss symmetry reductions of Chern-Simons theories on the disk, yielding a topological theory in two dimensions, which signals a curious relationship between symmetry reductions and the boundary conformal field theories. Finally, we study the Chern-Simons-Higgs instantons and show that under certain circumstances, the reduced action can formally be viewed as the action of a supersymmetric quantum mechanical model. We discuss the extent to which the reduced actions have a fermionic nature at the level of the partition function. Published by the American Physical Society 2024

Entanglement in ( 1+1 )-dimensional free scalar field theory: Tiptoeing between continuum and discrete formulations

We review some classic works on ground state entanglement entropy in (1+1)-dimensional free scalar field theory. We point out identifications between the methods for the calculation of entanglement entropy and we show how the formalism developed for the discretized theory can be utilized in order to obtain results in the continuous theory. We specify the entanglement spectrum and we calculate the entanglement entropy for the theory defined on an interval of finite length L. Finally, we derive the modular Hamiltonian directly, without using the modular flow, via the continuum limit of the expressions obtained in the discretized theory. In a specific coordinate system, the modular Hamiltonian assumes the form of a free field Hamiltonian on the Rindler wedge. Published by the American Physical Society 2024

Off-shell pion properties: Electromagnetic form factors and light-front wave functions

The off-shell pion electromagnetic form factors are explored with corresponding off-shell light-front wave functions modeled by constituent quark and antiquark. We apply the Mandelstam approach for the microscopic computation of the form factors relating the model parameters with the pion decay constant and charge radius. Analyzing the existing data on the cross sections for the Sullivan process, H1(e,e′,π+)n [H. P. Blok (Jefferson Lab Fπ Collaboration), Charged pion form factor between Q2=0.60, and 2.45 GeV2. I. Measurements of the cross section for the H1(e,e′π+)n reaction, .], we extract the off-shell pion form factor using the relation derived from the generalized Ward-Takahashi identity for the pion electromagnetic current. They are compared with our previous results [H.-M. Choi , Pion off-shell electromagnetic form factors: Data extraction and model analysis, .] from exactly solvable manifestly covariant model of a (3+1)-dimensional fermion field theory. We find that the adopted constituent quark model reproduces the extracted off-shell form factor F1(Q2,t) from the experimental data within a few percent difference and matches well with our previous theoretical simulation which exhibits a variation of about 10% for the extracted off-shell pion form factor g(Q2,t). We also identify the pion valence parton distribution function (PDF) and transverse momentum distribution (TMD) in terms of the light-front wave function and discuss their off-shell properties.

Study on the Impact of Cultural Differences on Sino-US Business Negotiations under the Guidance of Cultural Dimensions Theory

The tide of economic globalization has led to an increase in the frequency of business negotiations between China and the United States, where cultural differences have emerged as a pivotal factor affecting the success or failure of negotiations. Hofstede's cultural dimensions theory provides an effective analytical framework for understanding and analyzing cultural differences. Guided by Hofstede’s cultural dimensions theory, this paper delves into the impact of cultural differences on the objectives, language, risk-taking, and decision-making in Sino-US business negotiations. The aim is to uncover the intrinsic mechanisms of cultural differences and their multidimensional effects on negotiations, thereby offering strategic recommendations to facilitate the successful Sino-US business negotiations.

Handling missing data in variational autoencoder based item response theory.

Recently Variational Autoencoders (VAEs) have been proposed as a method to estimate high dimensional Item Response Theory (IRT) models on large datasets. Although these improve the efficiency of estimation drastically compared to traditional methods, they have no natural way to deal with missing values. In this paper, we adapt three existing methods from the VAE literature to the IRT setting and propose one new method. We compare the performance of the different VAE-based methods to each other and to marginal maximum likelihood estimation for increasing levels of missing data in a simulation study for both three- and ten-dimensional IRT models. Additionally, we demonstrate the use of the VAE-based models on an existing algebra test dataset. Results confirm that VAE-based methods are a time-efficient alternative to marginal maximum likelihood, but that a larger number of importance-weighted samples are needed when the proportion of missing values is large.

Flow-based nonperturbative simulation of first-order phase transitions

We present a flow-based method for simulating and calculating nucleation rates of first-order phase transitions in scalar field theory on a lattice. Motivated by recent advancements in machine learning tools, particularly normalizing flows for lattice field theory, we propose the “partitioning flow-based Markov chain Monte Carlo (PFMCMC) sampling” method to address two challenges encountered in normalizing flow applications for lattice field theory: the “mode-collapse” and “rare-event sampling” problems. Using a (2+1)-dimensional real scalar model as an example, we demonstrate the effectiveness of our PFMCMC method in modeling highly hierarchical order parameter probability distributions and simulating critical bubble configurations. These simulations are then used to facilitate the calculation of nucleation rates. We anticipate the application of this method to (3+1)-dimensional theories for studying realistic cosmological phase transitions.

The double‐edged sword effect of reading self‐concept on math achievement: Additional insights for making dimensional comparisons

AbstractA common belief underlying the dimensional comparison theory is that reading self‐concept has a positive relation to reading achievement but a negative relation to math achievement. However, this belief is incomplete and potentially misleading as supporting evidence is usually derived from studies without simultaneously considering the mediated effect of reading self‐concept through reading achievement. The current study examined the direct and indirect effects of reading self‐concept on math achievement through reading achievement, using PISA 2018 data from 501,766 students across 74 countries/territories. Multilevel structural equation modeling was performed to control for confounding variances from the school level and above. The results showed that reading self‐concept had a direct and negative effect on math achievement, while also exerting a positive indirect effect on math achievement through reading achievement. Overall, the indirect effect outperformed the negative direct effect on math achievement. We concluded that reading self‐concept exerted a double‐edged effect on math achievement. These results should be able to shed new light on the contrasting comparison effect of self‐concept on academic achievement.

A TIPIFICAÇÃO PENAL DOS CRIMES CIBERNÉTICOS NO DIREITO BRASILEIRO

This article, a descriptive and qualitative bibliographic research, based on authors such as Delgado (2017), Prado (2019), Souza and Ramalho (2022) among others, aims to discuss the way in which the Brazilian legal system has acted in the prevention and classification of cyber crimes. The work was structured in topics which correspond to its specific objectives as follows: bringing concepts of crime and criminal offenses and the way in which they are configured in Brazilian law; elucidate what would be a cyber crime and what are the requirements for its configuration; argue about the three dimensional theory of law (fact, value and norm) to justify governmental actions that lead to the classification of cyber crime. The conclusion reached was that Brazilian Criminal Law has been adapting to new situations and social facts that give rise to a legal response in defense of society.

Selection Rules of Linear and Nonlinear Polarization-Selective Absorption in Optically Dressed Matter

Dynamical symmetries of laser-dressed matter determine the selection rules that influence its absorption spectrum. We explore selection rules for polarization-sensitive absorption in Floquet matter, using Floquet group theory in synthetic dimensions. We present comprehensive tables of selection rules that polarization-structured light impose on Floquet dark states and Floquet dark bands. Notably, our tables encompass nonlinear absorption for all nonlinear orders, revealing that different nonlinear orders follow distinct polarization selection rules, potentially leading to polarization-tunable optical filters.

Covariant phase space formalism for fluctuating boundaries

We reconsider formulating D dimensional gauge theories, with the focus on the case of gravity theories, in spacetimes with boundaries. We extend covariant phase space formalism to the cases in which boundaries are allowed to fluctuate. We analyze the symplectic form, the freedoms (ambiguities), and its conservation for this case. We show that boundary fluctuations render all the surface charges integrable. We study the algebra of charges and its central extensions, charge conservation, and fluxes. We briefly comment on memory effects and questions regarding semiclassical aspects of black holes in the fluctuating boundary setup.

Entanglement in Lifshitz fermion theories

We study the static entanglement structure in (1+1)-dimensional free Dirac-fermion theory with Lifshitz symmetry and arbitrary integer dynamical critical exponent. This model is different from the one introduced in [Hartmann et al., SciPost Phys.11 (2021) 031] due to a proper treatment of the square Laplace operator. Dirac fermion Lifshitz theory is local as opposed to its scalar counterpart which strongly affects its entanglement structure. We show that there is quantum entanglement across arbitrary subregions in various pure (including the vacuum) and mixed states of this theory for arbitrary integer values of the dynamical critical exponent. Our numerical investigations show that quantum entanglement in this theory is tightly bounded from above. Such a bound and other physical properties of quantum entanglement are carefully explained from the correlation structure in these theories. A generalization to (2+1)-dimensions where the entanglement structure is seriously different is addressed.

Study on the Application of Intercultural Communication in Apparel Cross-Border E-commerce Livestreaming

With the rapid growth of global cross-border e-commerce, the apparel industry, as a key sector, has broken traditional marketing boundaries through e-commerce livestreaming and gradually entered the international market. However, due to significant differences in consumer needs and preferences across different cultural backgrounds, intercultural communication skills are crucial in cross-border e-commerce livestreaming. Based on Hofstede's cultural dimensions theory, this paper explores the application of intercultural communication in apparel cross-border e-commerce livestreaming. It analyzes how six cultural dimensions-high-context vs. low-context communication, power distance, individualism vs. collectivism, uncertainty avoidance, masculinity vs. femininity, indulgence vs. restraint-impact livestream communication and provides strategic suggestions for e-commerce livestream hosts to enhance communication in a cross-cultural context.

Anomaly inflow for dipole symmetry and higher form foliated field theories

In accordance with recent progress of fracton topological phases, unusual topological phases of matter hosting fractionalized quasiparticle excitations with mobility constraints, new type of symmetry is studied — multipole symmetry, associated with conservation of multipoles. Based on algebraic relation between dipole and global charges, we introduce a series of (d + 1)-dimensional BF theories with p-form gauge fields, which admit dipole of spatially extended excitations, and study their physical properties. We elucidate that gauge invariant loops have unusual form, containing linear function of the spatial coordinate, which leads to the position dependent braiding statistics and unusual ground state degeneracy dependence on the system size. We also show that the theories exhibit a mixed ’t Hooft anomaly between p-form and (d − p)-form dipole symmetries, which is canceled by an invertible theory defined in one dimensional higher via anomaly inflow mechanism.

Extending speech emotion recognition systems to non-prototypical emotions using mixed-emotion model

In the conventional approach to speech emotion recognition (SER), the classifier is usually trained on acted emotional speech data to predict individual basic emotions. In this work, we extend the SER systems with the realistic assumption of the coexistence of multiple basic emotions in an utterance. We utilize the MSP-Podcast database for developing the SER system, which contains spontaneous speech utterances. From the primary and secondary emotion annotations of this database, we organize six prototypical and seven non-prototypical emotions. We then propose the mixed-emotion model and express the non-prototypical emotions as a linear combination of prototypical emotions. The combination weights of the mixed-emotion model are computed using a normalized dominance scale based algorithm inspired by the integration of basic emotion theory and dimensional emotion theory in human psychology. We first train a prototypical SER model using the ECAPA-TDNN architecture. The softmax predictions from this model serve as emotion profile inputs to the mixed-emotion model, which then predicts the non-prototypical emotions. Assuming the coexistence of multiple emotions, we only apply the utterances with uniform emotion profiles to the mixed-emotion model. The developed system continues with the conventional SER model if the emotion profile tends to delta function owing to the probable occurrence of a single prototypical emotion. We develop the proposed mixed-emotion model based SER framework using MFCC and wav2vec 2.0 extracted features. Further, we show that due to human perception variations, there exist prominent annotation variations in the non-prototypical emotion ground truths. To address that, we extend the supervised evaluation protocols in four different formulations that capture the subjective variability at different levels. The proposed system shows a best-case performance improvement of 7.10% and 8.39% over the conventional prototypical SER model for the MFCC and wav2vec 2.0 features, respectively.
