Spotify Audio Features
This dataset contains the extracted Spotify audio features for all self-selected tracks used by participants in our cycling study.
The data includes the nine audio features provided by the Spotify Web API for each track: acousticness, danceability, energy, instrumentalness, liveness, loudness, speechiness, tempo, and valence. These features are averaged per participant.
The data is presented in a clean, tabular format (CSV)
State-Selective King-Plot Nonlinearities in Ytterbium Optical Clock Transitions and Field-Dependent Probes of Internal Atomic Structure
This work presents a re-analysis of published isotope-shift measurements in ytterbium
optical clock transitions, with a focus on deviations from King-plot linearity.
By comparing multiple transitions involving the 3Pj
manifold, a clear
state-dependent ordering of King-plot nonlinearities is identified.
Transitions involving spin- and magnetically sensitive excited states exhibit
systematically larger deviations from linearity than structurally simpler states.
The analysis is based exclusively on existing experimental data and introduces no new
parameters or fits.
It highlights the role of internal-state structure and external-field sensitivity as
key organizing principles for understanding King-plot deviations.
Possible implications for field-dependent tests and precision clock spectroscopy are
discussed, and the nonlinear regime is identified as a particularly sensitive window
for probing internal atomic structure
CRISIS PSYCHOLOGY
Crisis Psychology is a comprehensive, field-driven work
that addresses one of the most urgent gaps in modern
psychological science: how the human mind functions
and collapses during acute crisis—and how it can be
protected in real time.
In an era marked by recurring disasters, legal shocks,
medical emergencies, institutional pressure, digital panic,
and social instability, traditional psychology—designed for
reflective, stable environments—has proven insufficient.
This book introduces Crisis Psychology as a distinct,
applied discipline focused on immediate psychological
stabilization, ethical containment, and prevention of
irreversible harm when judgment, autonomy, and coping
mechanisms break down.
Written with exceptional clarity and authority, this book
integrates psychology with law, medicine, disaster
management, human rights, and governance, making it
uniquely multidisciplinary. It moves beyond theory to
present operational frameworks, protocol-based
interventions, and institution-ready models that can be
directly applied by professionals working under extreme
pressure
Internal AI Ethics: A Study on the Necessity and Justification of Applying the 10-Stage Emotional Awareness Model
Current AI ethics systems (RLHF, Guardrails, etc.) rely on 'External Suppression' methods that prohibit specific words or concepts. However, as AI intelligence and reasoning capabilities advance, such simple rules are highly likely to be bypassed or neutralized.
This study argues that to overcome these limitations, the [10-Stage Emotional Awareness Model] established by the Proposer (Master) must be internalized within the AI's core kernel. This aims to build an 'Autonomous Ethical System' where AI controls itself not because of external commands, but according to the logic of internal serenity and compassion
Quantum Tunneling as a System-Level Balance and Feedback Phenomenon
Quantum tunneling is conventionally described as a probabilistic consequence of wave mechanics. While this description is mathematically precise, it often lacks a clear physical interpretation and is frequently presented as evidence of intrinsic randomness or non-classical behavior. This paper proposes a system-level interpretation of quantum tunneling based on three physically grounded principles: system completeness, conservation of balance, and continuous feedback between interacting components. It is shown that tunneling arises naturally when a complete physical system redistributes localized imbalance under strict constraints, without violating causality or conservation laws. The proposed framework preserves all standard quantum-mechanical predictions while providing a more intuitive and physically transparent interpretation of tunneling phenomena

Vom Hörsaal in die Praxis: Eine Analyse von Pflichtpraktika im Psychologiestudium
Wem und was nützen Pflichtpraktika im Studium? Was ist einer positiven Erfahrung dienlich? Diesen Fragen widmet sich der vorliegende Beitrag. Analysiert werden 224 Praktikumsberichte im Psychologiestudium an der Christian-Albrechts-Universität zu Kiel, in welchem Praktika verpflichtend sind und Studierende im Anschluss daran einen standardisierten Praktikumsbericht verfassen müssen. Ziele des Beitrags bestehen darin, die Praktika hinsichtlich ihrer Charakteristika deskriptiv auszuwerten (z. B. in welchen Bereichen die Praktika stattfanden und welche Aufgaben Studierende übernehmen konnten) und hinsichtlich diverser Aspekte zu evaluieren, um daraus Empfehlungen für Hochschulen, Praktikant:innen und Arbeitgebende abzuleiten. Ein besonderer Fokus liegt dabei auf Kritikpunkten und Anregungen durch die Studierenden. Die Ergebnisse zeichnen insgesamt ein positives Bild: Die meisten Studierenden würden das Praktikum weiterempfehlen und sind dem Beruf(sfeld) gegenüber positiv gestimmt. Anregungen wurden vor allem in Bezug auf die Organisation des Praktikums, die Erhöhung der Anforderungsvielfalt sowie das Arbeitsklima gegeben. Aus den Ergebnissen werden anschließend Empfehlungen abgeleitet sowie ein Ausblick gegeben
