The mediating role of positive body image between friendship qualities, well-being strategies and identity development among adolescents

This study aimed to explore the mediating role of body image in the association between The utilization of strategies aimed at enhancing subjective well-being, friendship qualities, and identity development. The participants consisted of 270 early adolescents, comprising 157 girls (58.15%) and 113 boys (41.85%). Data were collected using several scales, including the “Body Appreciation Scale,” “Subjective Well-Being Increasing Strategies Scale for Adolescents,” “Friendship Qualities Scale,” and “The Dimensions of Identity Development Scale.” Two-stage structural equation modeling was employed to analyze the gathered data. The findings indicated a positive model of identity development in adolescents, highlighting that subjective well-being increasing strategies contribute positively to identity development, and this relationship is mediated by positive body image. Furthermore, the study found that positive body image also mediates the association between adolescents’ identity development and the establishment of quality friendships.

Work-Life Balance of Faculty in Professional Physical Therapist Education: A Mixed-Methods Study.

The purpose of this mixed-methods study was to explore perceptions of work-life balance (WLB) of full-time faculty in professional physical therapist (PT) education programs. Studies show that faculty are at risk of diminution of WLB and subsequent burnout due to job expectations and changing educational landscapes. Limited evidence exists to describe perceived WLB of faculty in professional PT education. Full-time faculty in professional PT education programs (n = 239) responded to an online survey and 16 participated in focus group discussions. The Work/Nonwork Interference and Enhancement Survey (W/NW Scale), faculty characteristic prompts, and open-ended questions were disseminated electronically to all accredited professional PT education programs within the United States. Focus groups were conducted to further explore nuances of WLB. Frequencies and percentages were calculated for survey categorical variables with means and standard deviations for continuous variables. Differences in W/NW Scale and faculty characteristics were analyzed using independent-samples Mann-Whitney U tests. Open coding and an iterative process of thematic analysis was used to analyze the qualitative data. Medians for all W/NW Scale dimensions were between 2 and 3 out of 5. W/NW Scale dimension scores differed significantly in each of the faculty characteristics of gender, defined workload, and faculty job searching (Z = -2.399 to -3.517, P ≤ .016). Qualitative data yielded 3 main themes: 1) implicit and explicit job duties; 2) leadership; and 3) individual boundaries. Ebb and flow of WLB emerged as an overarching theme. This study offers a portrayal of the lived experience of faculty regarding WLB. Results offer useful information about faculty demographics, work-related factors, and personal responsibilities. One limitation was that cultural, community, and religious demands were not explored. Findings may facilitate improved understanding of faculty WLB perceptions and can guide leadership to optimize the balance between faculty's paid work and personal life.

The impact of childhood trauma on Adolescent Depressive Symptoms: the Chain Mediating role of borderline personality traits and self-control

BackgroundThe adolescent depression associated with childhood trauma has been confirmed, but the underlying mechanisms remain unclear. This study aims to explore the chain-mediated role of borderline personality traits and self-control in the relationship between childhood trauma and adolescent depression.MethodsA cross-sectional study was conducted on 2,664 students from a senior high school through online questionnaires from October to December 2022 in Henan, China. Childhood Trauma Questionnaire-Short Form, Borderline Personality Dimension of Personality Diagnostic Questionnaire-4, Self-Control Scale, and Children’s Depression Inventory were used to measure childhood trauma, borderline personality traits, and self-control.ResultsThe prevalence of depression in adolescents was 21.17%, while the prevalence of borderline personality was 12.00%. childhood trauma (r = 0.50, p < 0.001) and borderline personality traits (r = 0.60, p < 0.001) were positively correlated with adolescent depressive symptoms, while self-control was negatively correlated with depressive symptoms (r = − 0.50, p < 0.001). Borderline personality traits and Self-control both play a mediating role in childhood trauma and depressive symptoms, and the mediating effect values are 0.116 (95%CI = [0.098, 0.137]), and 0.022 (95%CI = [0.012, 0.032]) respectively. The chain mediating effect of borderline personality traits and self-control on the relationship between childhood trauma and depressive symptoms was significant (effect value: 0.034, 95%CI = [0.028, 0.042]).ConclusionsChildhood trauma can predict depressive symptoms in adolescents due to the formation of borderline personality traits and the reduction of self-control. These findings are important for understanding the formation of personality traits, self-control abilities and coping strategies shaped by traumatic experiences in adolescents.

Interval prediction of crude oil spot price volatility: An improved hybrid model integrating decomposition strategy, IESN and ARIMA

Crude oil price volatility prediction are important for energy policymaking and investment risk avoidance, and have attracted a great deal of global attention. In recent years, although some studies have proposed methods for prediction crude oil price volatility, most of them are point prediction, which are difficult to provide richer reference information for managers. Therefore, an improved hybrid interval prediction model is proposed. The hybrid model combines data feature extraction and quantification techniques, fuzzy information granulation(FIG), improved echo state network (IESN), and autoregressive integrated moving average model (ARIMA). The hybrid model is able to accurately portray the different features present in the volatility of crude oil spot price. The features are quantified in order to merge similar feature components and improve the prediction effect. On this basis, IESN, which possesses strong nonlinear learning ability, is used to predict high-frequency sequences, and ARIMA, which has strong linear carving ability, is used to predict low-frequency sequences and residual terms. By “divide and conquer”, excellent prediction intervals are obtained. West Texas intermediate (WTI) crude oil spot and Brent crude oil spot are selected for analysis, and consider the influence of futures on interval construction. The effect of volatility intervals is validated from the pricing benchmark and time scale dimensions, respectively. The experimental results show that the proposed model has optimal performance in all scenarios. Take the performance of WTI on the daily scale as an example, its PICWC value is 0.8205. Compared with other benchmark models, it improves by 137.4504, 3.1118, 1.0506, and 0.4875, respectively. The proposed model provides a reliable new idea for crude oil spot volatility interval prediction.

Quantum Monte Carlo simulation of the 3D Ising transition on the fuzzy sphere

We present a numerical quantum Monte Carlo (QMC) method for simulating the 3D phase transition on the recently proposed fuzzy sphere [Phys. Rev. X 13, 021009 (2023)]. By introducing an additional SU(2) layer degree of freedom, we reformulate the model into a form suitable for sign-problem-free QMC simulation. From the finite-size-scaling, we show that this QMC-friendly model undergoes a quantum phase transition belonging to the 3D Ising universality class, and at the critical point we compute the scaling dimensions from the state-operator correspondence, which largely agrees with the prediction from the conformal field theory. These results pave the way to construct sign-problem-free models for QMC simulations on the fuzzy sphere, which could advance the future study on more sophisticated criticalities.

Entanglement asymmetry in CFT and its relation to non-topological defects

The entanglement asymmetry is an information based observable that quantifies the degree of symmetry breaking in a region of an extended quantum system. We investigate this measure in the ground state of one dimensional critical systems described by a CFT. Employing the correspondence between global symmetries and defects, the analysis of the entanglement asymmetry can be formulated in terms of partition functions on Riemann surfaces with multiple non-topological defect lines inserted at their branch cuts. For large subsystems, these partition functions are determined by the scaling dimension of the defects. This leads to our first main observation: at criticality, the entanglement asymmetry acquires a subleading contribution scaling as log ℓ/ℓ for large subsystem length ℓ. Then, as an illustrative example, we consider the XY spin chain, which has a critical line described by the massless Majorana fermion theory and explicitly breaks the U(1) symmetry associated with rotations about the z-axis. In this situation the corresponding defect is marginal. Leveraging conformal invariance, we relate the scaling dimension of these defects to the ground state energy of the massless Majorana fermion on a circle with equally-spaced point defects. We exploit this mapping to derive our second main result: the exact expression for the scaling dimension associated with n defects of arbitrary strengths. Our result generalizes a known formula for the n = 1 case derived in several previous works. We then use this exact scaling dimension to derive our third main result: the exact prefactor of the log ℓ/ℓ term in the asymmetry of the critical XY chain.

Controlling the broadband enhanced light chirality with L-shaped dielectric metamaterials

The inherently weak chiroptical responses of natural materials limit their usage for controlling and enhancing chiral light-matter interactions. Recently, several nanostructures with subwavelength scale dimensions were demonstrated, mainly due to the advent of nanofabrication technologies, as a potential alternative to efficiently enhance chirality. However, the intrinsic lossy nature of metals and the inherent narrowband response of dielectric planar thin films or metasurface structures pose severe limitations toward the practical realization of broadband and tailorable chiral systems. Here, we tackle these problems by designing all-dielectric silicon-based L-shaped optical metamaterials based on tilted nanopillars that exhibit broadband and enhanced chiroptical response in transmission operation. We use an emerging bottom-up fabrication approach, named glancing angle deposition, to assemble these dielectric metamaterials on a wafer scale. The reported strong chirality and optical anisotropic properties are controllable in terms of both amplitude and operating frequency by simply varying the shape and dimensions of the nanopillars. The presented nanostructures can be used in a plethora of emerging nanophotonic applications, such as chiral sensors, polarization filters, and spin-locked nanowaveguides.

Emergent symmetries at criticality in multi field RFT/DP

We study multifield extensions of Reggeon Field Theory (also equivalent to Directed Percolation model) at criticality in the perturbative ϵ-expansion below the upper critical dimension Dc = 4 at one loop, for the special case when all fields have the same scale (anomalous) dimensions. Analyzing all the fixed points of the renormalization group flow for N = 2 flavors and some for N = 3, we find scale invariant solutions which are characterized by specific emergent global symmetries of the interacting potential. We also study two infinite families as a function of N having ℤN and SN+1 symmetries.

Development of the imagination-creativity process scale in design

In this study, the undergraduate students’ Imagination–Creativity Process Scale (ICPS) in design was developed with reference to the Imagination–Creativity Process in design (Wang & Ho, 2021), and the scale reliability and validity were tested. Two samples of undergraduate students participated in test development, one for item revision and the other for validation. Sample 1 and 2 consisted of 285 and 488 students, respectively. Five to ten items were created for each scale dimension, resulting in a total of 31 items scored using a five-point Likert scale. A multidimensional Rasch partial-credit model was employed to verify the content and structural validity, generalizability, substantive validity, interpretive validity, and external validity of the scale. 30 items were retained for the final version of ICPS in design. The person separation reliabilities were 0.84, 0.83, 0.86, and 0.83, respectively for the four dimensions of the scale: (1) ideation and analysis, (2) generation and revision, (3) implementation and evaluation, and (4) communication and optimization. The results indicated that the ICPS had good model–data fit and was suitable for measuring undergraduate students’ Imagination–Creativity Process in design. Recommendations for future studies were proposed regarding the development and application of the ICPS in design.

Interpretasi Material Pada Rancang Bak Ukur Skala Laboratorium Dengan Pendekatan Konfigurasi Wenner, Wenner – Schlumberger dan Dipole-dipole

Geoelectric measurements have been carried out using multichannel ResistivityMeter (Geores) tools with Wenner, Wenner-Schlumberger, and Dipole-dipole Configuration approaches on the influence of materials arranged in a laboratory-scale measuring tub design with dimensions of 194x184x80 cm. The measured method is the variation in resistivity value against each trajectory of the material. The method used is the variation of resistivity values for each path of the material that has been arranged in a laboratory scale measuring design. Geoelectric measurements were carried out on 7 lines (5 line in the West-East direction and 2 line in the North-South direction). The spacing between the electrodes of each line is 10 cm with 16 electrodes in one line so that each line has a length of 160 cm or 1.6 m which corresponds to the length and width dimensions of a laboratory scale measuring design. The electrode arrangement parameters are constant with respect to changes in the configuration selected from the geores parameters during geoelectric measurements. The measurement results showed that the identified depth reached 31.2 cm. The low resistivity value category has an interval of 374-4,397 ohm.meters at a depth of 0-12.5 cm, which is the influence of building sand material containing water and soil, while the depth interval is 12.5 - 31.2 cm ohm.meters (material category that is influenced by 2 iron rods, tin tailings sand, granite, gravel) with resistivity values ranging from 12,378–67,498 ohm.meters. From experiments on the influence of the resistivity values of the three Wenner, Wenner-Schlumberger, and Dipole-dipole configurations, it was obtained that the smallest absolute error resistivity value in the Wenner configuration was 5.01% against the overall average absolute error resistivity value of 10.16%.

Thermal entanglement in conformal junctions

We consider a quantum junction described by a 1+1-dimensional boundary conformal field theory (BCFT). Our analysis focuses on correlations emerging at finite temperature, achieved through the computation of entanglement measures. Our approach relies on characterizing correlation functions of twist fields using BCFT techniques. We provide non-perturbative predictions for the crossover between low and high temperatures. An intriguing interplay between bulk and boundary effects, associated with the bulk/boundary scaling dimensions of the fields above, is found. In particular, the entanglement entropy is primarily influenced by bulk thermal fluctuations, exhibiting extensiveness for large system sizes with a prefactor independent of the scattering properties of the defect. In contrast, negativity is governed by fluctuations across the entangling points only, adhering to an area law; its value depends non-trivially on the defect, and it diverges logarithmically as the temperature is decreased. To validate our predictions, we numerically check them for free fermions on the lattice, finding good agreement.

Solving conformal defects in 3D conformal field theory using fuzzy sphere regularization

Defects in conformal field theory (CFT) are of significant theoretical and experimental importance. The presence of defects theoretically enriches the structure of the CFT, but at the same time, it makes it more challenging to study, especially in dimensions higher than two. Here, we demonstrate that the recently-developed theoretical scheme, fuzzy (non-commutative) sphere regularization, provides a powerful lens through which one can dissect the defect of 3D CFTs in a transparent way. As a notable example, we study the magnetic line defect of 3D Ising CFT and clearly demonstrate that it flows to a conformal defect fixed point. We have identified 6 low-lying defect primary operators, including the displacement operator, and accurately extract their scaling dimensions through the state-operator correspondence. Moreover, we also compute one-point bulk correlators and two-point bulk-defect correlators, which show great agreement with predictions of defect conformal symmetry, and from which we extract various bulk-defect operator product expansion coefficients. Our work demonstrates that the fuzzy sphere offers a powerful tool for exploring the rich physics in 3D defect CFTs.

Budżety partycypacyjne na uczelniach w Polsce jako narzędzie edukacji młodych obywateli

In addition to enabling students to acquire the knowledge and competencies necessary for their professions, higher education institutions should also support the formation of broad civic attitudes among students. University participatory budgets (PB) are an example of a tool for reaching this goal. The purpose of the presented research was to analyse the degree and scope of their use by public universities in Poland, with particular focus on the context in which PBs educate young citizens. The aim of the study was to fill the research gap regarding the lack of knowledge about the scale, importance and potential educational dimensions of PB implemented at public universities, by means of analysing the use of PBs at all 92 public universities. To this end, the budget regulations, orders, informational material and other documents available on the universities’ websites regarding participatory budgets were studied, which enabled the identification of 19 universities that implement processes meeting PB criteria, and 17 of including students in the process. Analysis of the data showed significant variation in terms of the scale, scope and stakeholders involved in BP processes, and although it should be noted that the educational goals are not directly indicated by universities, a number of activities were identified in the research that could ensure the achievement of differentiated educational outcomes at different stages of the PB process.

Navigating Through the Digital Workplace: Measuring Leader Digital Competence

AbstractIn a modern digital workplace, leaders must have the necessary skills to lead employees virtually. Despite its high practical and theoretical relevance, a consensus on crucial digital competencies for virtual leaders is lacking, hindering a systematic exploration of the leader’s role in facilitating technology use. In the present article, we propose a new concept and instrument to assess leader digital competence (LDC). After reviewing the literature, we establish three dimensions of LDC, centering around the leader’s ability and inclination to select, promote, and enable technology and digital media among their employees. We provide support for the scale's convergent, discriminant, criterion-related, and incremental validity using four independent samples (N1 = 156, N2 = 309, N3 = 201, N4 employee = 452, N4 leader = 93). Furthermore, results support the reliability and factor structure with the three proposed dimensions of the 10-item LDC scale. The findings demonstrate that the scale represents a psychometrically sound instrument, useful for further examining conditions for effectiveness in the virtual environment. Future research should aim to advance the understanding of antecedents and situational factors that influence the relevance of LDC and its impact on employee, team, and organizational outcomes.

Experimental Observation of the Yang-Lee Quantum Criticality in Open Quantum Systems.

The Yang-Lee edge singularity was originally studied from the standpoint of mathematical foundations of phase transitions. However, direct observation of anomalous scaling with the negative scaling dimension has remained elusive due to an imaginary magnetic field required for the nonunitary criticality. We experimentally implement an imaginary magnetic field with an open quantum system of heralded single photons, directly measure the partition function, and demonstrate the Yang-Lee edge singularity via the quantum-classical correspondence. We also demonstrate unconventional scaling laws for finite-temperature quantum dynamics.

Self-care practice in young adults with type 2 diabetes mellitus

Introduction: self-care in young adults is recognized as a crucial strategy for addressing Type II Diabetes Mellitus and improving patients' quality of life. It is essential to demonstrate the proper development of these practices to ensure their effectiveness.Objective: to determine the self-care capability in young adults with Type II Diabetes Mellitus. Methodology: a descriptive and cross-sectional study was conducted on 152 young adult residents of a community in the Sierra region of the state of Guerrero. Data collection was carried out using the Self-Care Agency Assessment Scale and a data form. Data analysis was developed using the SPSS v22 statistical package. Results: females predominated with 54,6 %, and the majority were married (46,7 %). The average age was 29 years, and 42,7 % had established diabetes for 1-5 years, the predominant range in the self-care timeframe (47,4 %). According to the scale used, patients showed moderately adequate self-care knowledge. Regarding the scale's dimensions, most demonstrated moderately adequate capabilities, except in the nutrition dimension, where a low self-care capability of 77,6 % was observed. Conclusion: although current habits and behaviors reflect a moderately adequate style, except in relation to nutrition, it is recommended to inquire more deeply as this could be related to other elements. The role of health personnel is fundamental, and it is suggested to implement educational strategies to promote self-care

Pursuing travel calculated hedonism: scale development and validation

ABSTRACT This research investigates travel calculated hedonism (TCH) in diverse tourism contexts. An extant literature review, five focus groups and two expert panels conceptualised TCH. Field studies operationalised TCH in drinking (N = 355), eating (N = 351), wellness (N = 330) and shopping (N = 337) contexts. Findings identified four TCH scale dimensions – delaying rewards, planned impulsiveness, planned financial compulsiveness and planned time/physical compulsiveness. Theoretical definitions of TCH set the groundwork for rationalised binging that is cognitive- and affect-driven. The methodology presents an approach for a rigorous TCH measure. The TCH scale offers a tool for practitioners to design activities that instigate rationalised binging and responsible behaviour.

Emotional regulation and self-perceived quality of life in high-performance mountain sports athletes.

Emotional regulation is an indispensable capacity for human beings, so that alterations in it can lead to the appearance of psychological, social and/or cognitive disorders. Therefore, possessing adequate emotional strategies is intimately related to the quality of life that a person presents. In this sense, high-level athletes suffer constant setbacks and frustrations due to the performance of their sporting activity, in addition to continuous modifications of their daily life activities. Thus, the objective of this research is to explore the emotional regulation and self-perceived quality of life of high-level athletes in mountain sports, analyzing the possible influences of gender, demographic location, body mass index and age. Fifty-four athletes belonging to the High Performance Technification Center of Cáceres (Extremadura, Spain) completed a sociodemographic questionnaire, as well as the Cognitive Emotion Regulation Questionnaire and the WHOQOL-BREF. The Shapiro-Wilkins test was used to analyze the normality of the variables collected and nonparametric statistics were used since the assumption was not met. Both gender and demographic location showed significant differences in the dimensions of the two questionnaires. Likewise, age was associated with the dimensions of both scales, but not body mass index, which was only associated with self-perceived quality of life. In addition, the stepwise linear regression model predicted self-perceived quality of life with a value of 60% across self-culpability, gender body mass index and planning. Therefore, it appears that gender, demographic location, age and body mass index could exert modifications on the levels of emotional regulation and self-perceived quality of life of high-level mountain athletes.

Investigation of the scalar unparticle and anomalous couplings at muon colliders in final states with multiple photons in the Randall–Sundrum model

The influence of the scalar unparticle and anomalous couplings at muon colliders in final states with multiple photons in the Randall–Sundrum model is evaluated in detail. The results indicate that with fixed collision energies, the total cross-sections for the production of multiple photons depend strongly on the polarization of the muon beams, the parameters of unparticle physics (the scaling dimension [Formula: see text], operator [Formula: see text], the energy scale [Formula: see text]) and also the strength of anomalous couplings. Numerical evaluation shows that the cross-sections for the production of four photons in finale states with the contribution of scalar anomalous couplings are much larger than that of the unparticle under the same conditions. In the Higgs–radion mixing, the cross-sections achieve the maximum value at the radion-dominated state, [Formula: see text][Formula: see text]GeV, in which the cross-section is much enhanced and can be measurable in current experiments.
