Spread complexity in saddle-dominated scrambling

Recently, the concept of spread complexity, Krylov complexity for states, has been introduced as a measure of the complexity and chaoticity of quantum systems. In this paper, we study the spread complexity of the thermofield double state within integrable systems that exhibit saddle-dominated scrambling. Specifically, we focus on the Lipkin-Meshkov-Glick model and the inverted harmonic oscillator as representative examples of quantum mechanical systems featuring saddle-dominated scrambling. Applying the Lanczos algorithm, our numerical investigation reveals that the spread complexity in these systems exhibits features reminiscent of chaotic systems, displaying a distinctive ramp-peak-slope-plateau pattern. Our results indicate that, although spread complexity serves as a valuable probe, accurately diagnosing true quantum chaos generally necessitates additional physical input. We also explore the relationship between spread complexity, the spectral form factor, and the transition probability within the Krylov space. We provide analytical confirmation of our numerical results, validating the Ehrenfest theorem of complexity and identifying a distinct quadratic behavior in the early-time regime of spread complexity.

‘My multiple cultural backgrounds are pulling me in all directions with my identity’: Asian and Latino Canadian youth experiences of cultural identity

ABSTRACT Identity, diversity, and inclusion are constantly being reshaped in the face of global migration and resettlement. New research is needed that examines youth identities. In this article, we analyse Asian and Latino youth’s understandings and experiences of how their cultural identity has been influenced by exclusion, inequitable access and racism on the part of their host society. We report on a qualitative study; focus groups (2) and individual interviews were conducted with 15 youth participants. Analysis process included code-driven guided by grounded theory. Youth narratives resisted oversimplified representations by inserting their gendered, minority, and youth identity within mainstream multicultural narratives to make visible immigrant youth experiences. Interwoven in youth’s narratives were experiences of racial discrimination, gender inequality, and indeterminate belonging. Cultural identity is a complex and changing concept. We analyse how youth living in multicultural view their need to negotiate their identities to adapt to their challenging multicultural context where they live.

Local economic development strategies in a medium-sized city on the European periphery: a path to become an economic center of Eastern Central Europe importance

Large cities are becoming increasingly valuable in the spatial structure of globalized economies. Although these centers vary significantly regarding population, economic structure, and income conditions, they—compared to their surroundings—generally show a higher productivity level, a higher rate of employment, higher education, and higher innovation performance. However, this metropolization and concentration of the economy in large cities made the development of cities regarded as medium-sized on an international scale an issue of competitiveness in Europe, characterized by dense town networks, a small number of metropolises, and a significant weight of medium- and small-sized towns. However, one of the main preconditions for achieving success in this competition is to form a comprehensive and complex concept with a significant emphasis on economic development. Therefore, the aim of our study is to analyze the local economic development strategies for the last three decades, as elaborated in Debrecen. In the framework of our empirical analysis, we examined how different mainstream concepts appear in local development strategies and which development objectives are determined by the local strategies. Furthermore, we also aimed to identify possible changes in ideas about city roles by referring to the organization of economic space.

Believing in the power of belief: a study on the formation mechanism of innovative behavior from the perspectives of intrinsic and extrinsic spiritual inspiration

PurposeThis study reveals the trigger of innovative behavior from the perspective of intrinsic and extrinsic spiritual inspiration and provides a new research idea for the formation mechanism of innovative behavior. The purpose of this study is to provide certain guidance and implications for enterprises to cultivate and enhance employees’ innovative behavior.Design/methodology/approachWe conducted three studies, collected multi-source data (N = 1,175) from different countries longitudinally, as well as used hierarchical regression analysis and fuzzy-set quantitative comparative analysis to verify the theoretical model.FindingsAccording to the findings, both spiritual leadership and career calling have a positive impact on employees’ innovative behavior through the mediating effect of autonomous motivation and the moderating effect of person-vocation fit.Originality/valueInnovative behavior is the positive professional pursuit of employees, which is difficult to form without the motivation of spiritual factors. Spirituality is a complex concept that contains intrinsic and extrinsic spiritual factors, both of which could stimulate employees’ innovative behavior. Although many discussions have been held on this topic in recent years, little attention has been paid simultaneously to the motivating effects of the two perspectives. Drawn from self-determination theory, this study explores the mechanisms of two spiritual motivation paths (i.e. the intrinsic and extrinsic spiritual motivation paths) in the improvement of employees’ innovative behavior.

A Hybrid Escape Room to Foster Motivation and Programming Education for Pre-Service Teachers

Educational escape rooms aims to motivate students, to strengthen knowledge and evaluate learning. Pre-service teachers enrolled in “Computer Science and Digital Competency” course shows lack of motivation and difficulties to realise its usefulness in everyday practice, becoming an ideal context to apply this strategy. 157 students belonging to a European university participated in the experience as case study. The educational escape room was conducted following a hybrid model, mixing a physical organization of props with a virtual organization of the narrative, tests and achievements. The experiment was designed to answer two hypotheses, first if applying escape room as an educational strategy fosters pre-primary and primary students' motivation, since this method address complex concepts in a practical way, and second, if the application of this strategy as teaching strategy makes students perceive the learning process as a game.

Medical eponyms versus acronyms: what medical terminology is most beneficial to learn? A question of goals.

Appropriate use of medical terminology is one of the core conditions for successful communication in monolingual and multilingual healthcare communities. The modern scientific language is based on the descriptive terminology. However, it is often the case that the advantages of descriptive terminology are at odds with the ability to express complex concepts in just a few words. To solve this practicality problem it is customary to coin abbreviations and acronyms preferred to traditional eponyms. Today eponyms are considered ambiguous and non-descriptive, linked to the terminology of the past. The overview of this study demonstrates that the current habit of using acronyms can increase the scientific descriptive capacity compared to eponyms. On the other hand, acronyms remain ambiguous and more ephemeral than eponyms. Furthermore, eponyms are not as descriptive as acronyms, but they still carry important information for a medical student. If you truly believe in the importance of Medical Humanities in the medical curriculum, two aspects cannot be overlooked. First, eponyms bring students closer in an almost subliminal way to the history of medicine and the non-strictly technical-scientific field of medicine. Second, medicine is a complex science applied to humans and must strive to keep the patient at the center of its interests. Patients and their families preferably ask us to use eponyms. Which terminology to choose for medical students? The teachers have the last word.

Cinemeducation to teach patient safety: an experience in medical students

From early in medical school, students need to learn about patient safety, and how to prevent and reduce risks, errors and harm that occur to patients during health care provision. Cinemeducation is a teaching methodology that uses fragments of feature films or TV series in medical education. We hypothesized that cinemeducation could help simplify the comprehension of complex situations for students, aiding in the learning of patient safety and the understanding of human behaviors that impact it. This concept stands as an integral component within a comprehensive medical humanities approach. The study population was the 70 medical students of the second course of a six-year undergraduate program. In a 2-h class, after learning objectives were established, students watched a fragment from TV series The Resident centered on adverse events, and discussed them afterward. To measure learning achievements, we administered a 10-question multiple-choice pre and post-test and a 2-question open-essay post-test. Given the complexity of the concepts related to patient safety, we used a mixed quali-quantitative approach. An exploratory descriptive and content analysis was performed. Sixty-eight students participated and completed the questionnaires. Despite high pre-intervention scores, post-intervention scores improved (mean difference 0.779, 95% CI: 0.475–1.083, p < 0.001). The open-essay questions provided more information about the learning points, mostly related to the understanding of system error and preventive measures against adverse events. Classical teaching methods may be insufficient for learning how to deal with complex situations in hospital contexts. Our results show that cinemeducation may significantly improve learning on patient safety. Cinemeducation methodology can be effective in teaching some complex concepts in medical education. The integration of cinemeducation within medical education, through the lens of medical humanities, offers a dynamic approach to teaching patient safety. By using cinematic narratives to explore intricate medical scenarios, students engage with real-world complexities and the influence of human factor, enhancing their understanding.

Project-based learning approach on content mastery and cognitive skills: a pedagogical model for senior high school biology students

The principal objective of this study was to determine the effectiveness of a project-based learning approach on the performance level and engagement experience of Senior High School Biology students. Quasi-experimental, specifically the One-Group-Pretest-Posttest Design was employed using mean percentage score and t-test as statistical tools in the treatment of data. The findings revealed that the mean percentage score of students across content areas and cognitive skills did not meet the expectations and were interpreted as being at the beginning level. Nevertheless, there is a significant difference between the pretest and posttest results covering content areas, namely: cells, biological molecules, and energy transformation. Likewise, a significant difference was revealed between the pretest and posttest scores throughout cognitive skills, such as comprehension, analysis, and application. The results suggest that the study can be very helpful to teachers of 21st-century learners so that they can have meaningful engagement in the class by exposing them to project tasks that develop their creativity, critical thinking skills, collaboration, ownership, and self-reflection. In addition, teachers should reinforce basic concepts, employ visual aids, foster active learning, stimulate critical thinking, and adopt an inquiry-based approach. They must also facilitate collaborative learning, ensure inclusivity, enhance project-based learning using models, cultivate metacognitive skills, and simplify complex concepts through scaffolding.

Semiotic Functions of Indexicality

By exploring how indexical signals interact with other semiotic components, as well as how social context affects their interpretation, this study fills a research gap and examines the complex function that these signs play in influencing meaning-making within communication. The present study employed theme analysis to look at public speeches, social media posts, and ads that promoted environmental awareness and community involvement. Themes about social action and environmental responsibility evolved, along with the identification of indexical signals. A comparative examination showed that although basic themes were shared across societies, how particular indications were interpreted differed according to social and cultural situations. Indexical signals interact with other semiotic components to create meaning, as demonstrated by semiotic analysis. This study underscores the significance of indexicality in communicating complex concepts and the necessity of employing culturally sensitive communication techniques. These results might be useful in developing messages that effectively encourage global community involvement and environmental awareness.

Dynamic Model Interpretation-Guided Online Active Learning Scheme for Real-Time Safety Assessment.

Chunk-level real-time safety assessment of dynamic systems is a critical component of industrial processes, which is essential to prevent hazards and reduce the risk of injury or damage to equipment and facilities, especially in nonstationary environments. In this context, multiple real and complex concept drifts are inevitable in industrial settings, making it crucial to understand their detection and adaptation processes. The incremental learning scheme should also be well considered. However, existing methods have certain limitations in dealing with such issues. In this article, a dynamic model interpretation-guided online active learning scheme, termed a dynamic model interpretation-guided learning scheme (DMI-LS), is proposed. Specifically, the model update strategy with chunk data is designed based on the implementation of the broad learning system. A novel query strategy is then investigated to consider the ranking preference difference, which relies on the interpretation generated by the explainable artificial intelligence method. Several experiments based on the JiaoLong deep-sea manned submersible data are conducted to verify the effects of the proposed DMI-LS. The results show that it outperforms the other advanced existing approaches with different settings in most scenarios.

Measuring empathy in youth and young adults with mild intellectual disabilities or borderline intelligence in residential care - The validation of an adapted basic empathy scale: The BES-MID

Youths with mild intellectual disability (MID) are assumed to show impaired cognitive and affective empathy. However, the use of linguistic and conceptual complex empathy measures set limits to the valid and reliable assessment of empathy in youth with MID or borderline intelligence (BI). The objective of the present study was to evaluate the validity and reliability of the adapted BES-MID as an instrument for assessing cognitive and affective empathy in youth and young adults (12–24years) with MID/BI. The current study was conducted in a sample of N = 146 youth and young adults with MID or BI Results from Confirmatory Factor Analyses confirm the two-factor structure of affective and cognitive empathy for the BES-MID. While the original BES cannot be used to assess empathy in youth and young adults with MID or borderline intelligence, the BES-MID showed satisfactory validity and reliability in youth and young adults with MID or borderline intelligence. Despite some limitations and the need for further research, the current study has resulted in a valid and reliable empathy scale (BES-MID) for assessing cognitive and empathic abilities in youth and young adults with MID or borderline intelligence, which is important for future empathy research in youth and young adults with MID or borderline intelligence.

SIXTH GRADE STUDENTS' MISCONCEPTIONS ON DECIMAL NUMBERS THROUGH ROUTINE EXERCISE QUESTIONS

Mathematics is an important subject in elementary school because it is the basis for understanding more complex mathematical concepts in the future. One of them is that students need to study number material in basic mathematical concepts because it is very important to master and understand, for example it can be used in commerce, measurement and technology. However, in the field, elementary school students are still found to have misconceptions about understanding the concept of comparing, ordering or calculating decimal numbers. This research uses a qualitative approach with a case study method. The subjects of this research were 4 class VI students at an elementary school in Banyuresmi sub-district, Garut. Data was collected through observation, interviews, and providing routine practice question sheets. The findings in this research are, 1) Some students have difficulty understanding decimal numbers and ordering them as well as performing addition calculation operations, 2) Some students consider decimal numbers with more digits after the comma as larger numbers, 3) There are also students who make mistakes. Storing numbers after commas can cause errors in calculations. So the alternative solution that can be given is that teachers can identify the source of student misconceptions by providing diagnostic tests, using more interactive learning methods, providing case examples from everyday life, providing more and varied exercises, providing continuous feedback. and be constructive towards student answers, and facilitate discussions that focus on problem solving. This will help students understand the concept of decimal numbers more effectively and efficiently.
