Mathematical Foundations of the Higher-Dimensional Information Field (Part 5): Rigorous Formulation of Projection Kernels and Nonlinear Dynamics
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper presents the mathematical and theoretical foundations of a higher-dimensional information field as Part 5 of the Entropy-Induced Collapse (EIC) Model Series (2025). It rigorously formulates how an information field, Φ(x,t), emerges as a non-equilibrium fifth force mediated by entropy gradients and projected onto 3+1 spacetime. Extending previous works, this paper introduces a consistent framework for projection kernels, activation functions, and fractal stochastic dynamics underlying the information field.

 

Key contributions of this work include:

 1. Formal derivation of projection kernels and activation functions that selectively project the higher-dimensional information field Φ_H(y) based on local entropy gradients.

 2. Mathematical formulation of the Lagrangian and field equations for Φ(x,t), where entropy gradients serve as a dynamic source of “information energy.”

 3. Integration of fractal stochastic differential equations to model non-Markovian and long-memory effects in entropy dynamics.

 4. Comparative analysis with existing fifth-force theories, highlighting how this model uniquely avoids Equivalence Principle violations by coupling to entropy gradients rather than mass.

 5. Experimental prospects for verifying the model through short-, mid-, and long-term tests, including MEMS sensors, Casimir effect, and cosmological observations.

 6. Ethical statement emphasizing that all aspects of this research are solely intended for peaceful scientific development and must never be used for military or harmful purposes.

 

This work establishes a novel theoretical and mathematical foundation for a fundamentally new type of interaction, potentially bridging quantum measurement, gravity, and non-equilibrium physics through the lens of information dynamics.

'As good as it gets': young Victorians' experiences in flexible learning environments
Creators: name: Randall, Linda
Publisher: name: Swinburne
Year: 2024

description: This thesis makes a contribution to knowledge about the role of education in shaping the life chances of young people through an exploration of young Victorians' experiences in flexible learning environments. The findings presented here are based on qualitative interviews with nineteen young people completing year 10 and 11 qualifications through community organisations and TAFEs. They demonstrate that, despite having experienced difficulties in the mainstream education system, young people re-engage enthusiastically with learning once they find environments that cater appropriately to their needs. Although there were many factors that contributed to this, a central consideration was giving young people the opportunity to take ownership of their own learning and, by implication, their own lives. As a result this thesis challenges the current Governmental position on flexible learning environments as a ‘last chance’ at learning. Through an approach that acknowledged young people as the experts when it comes to their own lives, it found support for the idea that these programs should be repositioned as a real opportunity. It also found that young people not only want to have a say when it comes to policy decisions that affect their lives, they have valuable ideas to contribute.

description: A current trend in HPC systems is the utilization of architectures with SIMD or vector extensions to exploit data parallelism. There are several ways to take advantage of such modern vector architectures, each with a different impact on the code and its portability. For example, the use of intrinsics, guided vectorization via pragmas, or compiler autovectorization. Our objectives are to maximize vectorization efficiency and minimize code specialization. To achieve these objectives, we rely on compiler autovectorization. We leverage a set of hardware and software tools that allow us to analyze in detail where autovectorization is suboptimal. Thus, we apply an iterative methodology that allows us to incrementally improve the efficient use of the underlying hardware. In this paper, we apply this methodology to a CFD production code. We evaluate the performance on an innovative configurable platform powered by a RISC-V core coupled with a wide vector unit capable of operating with up to 256 double precision elements. Following the vectorization process, we demonstrate a single-core speedup of 7.6$\times$ compared to its scalar implementation. Furthermore, we show that code portability is not compromised, as our solution continues to exhibit performance benefits, or at the very least, no drawbacks, on other HPC architectures such as Intel x86 and NEC SX-Aurora.

title: Protein synthesis in the liver and small intestine of the rat
Creators: name: McNurlan, MA
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 1980

description: This thesis, presented in four sections, is concerned with the regulation of protein metabolism in the liver and small intestine of the rat. Section 1. A method was developed which allows for the measurement of rates of protein synthesis in tissues such as liver and intestine which synthesise and degrade protein very rapidly. The method employed a flooding amount of (14C)leucine (100umoles per 100g body weight) injected intravenously with measurement of the rate of incorporation of labelled leucine into protein over the following 10 minutes. Several experiments were performed to show that protein synthesis, per se, was unaltered by the flooding amount of leucine. Section 2. Employing the method described in Section 1, protein synthesis was measured in the liver and the individual components of the gastro-intestinal tract and in the whole animal. These measurements demonstrated the importance of these rapidly turning over tissues to overall protein metabolism in the whole animal. Section 3. Nutritional and hormonal perturbations leading to the loss of body protein were investigated. Rates of protein synthesis in the liver and small intestine have been examined under three conditions; namely, starvation, dietary protein-deprivation and diabetes. Each of these conditions caused a loss of protein from the liver and a lowered rate of synthesis but by different Intracellular mechanisms. In the intestine the synthesis of protein was depressed by starvation and protein-deprivation but maintained in diabetes. Section 4. The role of leucine as a regulator of protein synthesis was examined. Protein synthesis was measured using a flooding amount of (-H)phenylalanine in the presence and absence of l00umoles of unlabelled leucine. The impact of leucine on protein synthesis in liver, intestine and muscle of fed, starved and protein-deprived animals appeared to be negligible in vivo, inspite of many reports that leucine stimulated protein synthesis in vitro.
Experimental Proposals and Standard Model Extensions of the Information Field: Applications of the EIC Model (Part 6)
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper is part of the Entropy-Induced Collapse (EIC) Model Series (2025). It proposes a novel extension of the EIC model by introducing an information field, denoted as Φ(x,t), which is driven by local entropy gradients and mediates a non-equilibrium fifth force. Unlike previous collapse models such as CSL and GRW, this approach incorporates a higher-dimensional informational field that interacts with Standard Model particles under non-equilibrium conditions, while remaining hidden in equilibrium states.

 

The paper formulates detailed interaction terms between Φ(x,t) and Standard Model fields (Higgs, fermions, gauge fields), derives projected kernels with fractal structures, and proposes concrete experimental setups including MEMS sensors, superconducting qubits, Casimir effect modifications, and gravitational tests. It also offers a reinterpretation of existing experimental anomalies, such as the Muon g−2 and Atomki X17 anomalies, within this novel framework.

 

Furthermore, this work suggests a possible unification of gravity and information dynamics via modified Einstein field equations incorporating Φ(x,t), providing new perspectives on dark matter, dark energy, and black hole thermodynamics.

 

This research reflects a broader commitment to democratizing science through AI-assisted research and interdisciplinary collaboration. It is part of a comprehensive theoretical effort aiming to bridge fundamental physics, quantum mechanics, and information theory.
Dark Matter and Dark Energy from the Perspective of the Higher-Dimensional Information Field: A Novel Hypothesis within the Entropy-Induced Collapse (EIC) Framework
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper is part of the Entropy-Induced Collapse (EIC) Model Series (2025). It proposes a novel extension of the EIC framework by introducing a higher-dimensional information field \Phi(x,t) that becomes physically relevant under local or global entropy gradients. This field, projected from a higher-dimensional informational substrate, offers a unified explanation for dark matter and dark energy.

 

In this hypothesis, localized condensations of \Phi(x,t) produce gravitational effects that mimic dark matter, while global activations account for the accelerated expansion of the universe. The model naturally integrates into modified Einstein field equations and provides a new interpretation of cosmological observations such as galactic rotation curves, Type Ia supernovae, and the CMB polarization spectrum.

 

The paper derives the Lagrangian for the information field, constructs the corresponding energy-momentum tensor, and formulates experimental proposals involving MEMS gravimeters, superconducting qubits, and gravitational wave detectors. These experiments aim to detect gravitational signatures of entropy-driven information field activation.

 

This research builds on prior work in the EIC model series, which integrates non-equilibrium thermodynamics, quantum collapse, and quantum information theory. It reflects a broader vision of unifying gravity, quantum mechanics, and information through experimentally testable models.

description: Polarizer miter bends are used to alter the polarization in overmoded waveguides. For future space debris observation with broadband high power W-band radar sensors these are important transmission line components. A polarizer miter bend uses a grooved mirror as phase grid for polarization. The present paper addresses a suitable design of such a phase grid for broadband high power radar applications within the frequency range from 90GHz to 100GHz. An appropriate parameter combination is found by a parametric study. For reduction of the required amount of calculation a plane wave approximation and unit cell simulations are used. With a suitable parameter combination a cross polarization of Xpol B −26 dB can be achieved within the considered frequency range. This corresponds to a suitable value for radar applications.

description: The main objective of this paper is to present a general mathematical model and an associated numerical algorithm applicable to an arbitrary fixed-wing fixed-mass aircraft undergoing an arbitrary maneuver, based on the 3D nonlinear coupled differential-algebraic equations of motion, including force, moment, kinematic and constraint equations. The model is formulated to address the inverse simulation problem where a target maneuver is prescribed and the corresponding time dependent patterns of the control variables are solved for to meet this maneuver. The model utilizes two different moving frames of references, namely the body axes and the wind axes. The numerical algorithm features sequential solution of equations in a fully explicit manner. It is straightforward to use the model in a reverse mode, namely the direct simulation problem. The inverse problem may be summarized as follows: Inputs: Time history of desired-trajectory rectangular coordinates relative to the ground-fixed axes. A constraint should be specified, which we arbitrarily chose it to be the bank angle. Also, certain geometric and aerodynamic aircraft data are needed. Outputs: Time history of the control variables (thrust magnitude, elevator angle, rudder angle, ailerons angle), which will satisfy the aimed trajectory. The paper finally applies the presented numerical algorithm to a roll maneuver for the Mirage-III fighter.

• Enhanced Experimental Proposals: Predictions for MEMS, Casimir, and CMB measurements are refined, including expected force magnitudes.

• Expanded Appendix: Mathematical derivations, simulation details, and GitHub link for reproducibility are newly included.

• Ethical Commitment Statement: An explicit section is added to emphasize peaceful and ethical applications of the theory.

 

This update is intended to be a cornerstone for future work in Information Field Theory, and we encourage readers to engage with the full EIC Model Series to appreciate its unified vision.
Seahorses (Hippocampus spp.) and the CITES Review of Significant Trade
Creators: name: Foster, Sarah J.
Publisher: name: The University of British Columbia
Year: 2017

description: The international trade in wildlife is vast, and if allowed to carry on unchecked can pose a significant threat to the world’s biodiversity. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) is a multilateral environmental agreement (MEA) that aims to regulate international trade of animals and plants, in order to ensure that trade does not threaten survival of wild populations. It is unique among MEAs, in that it has legal mechanisms in place to promote compliance with agreed restrictions on exports. One of these mechanisms is known as the Review of Significant Trade (RST, Res. Conf.12.8 (Rev. CoP13)). The RST identifies any challenges member States (Parties) are facing in implementing certain requirements of the Convention for species for which trade is allowed, but must be regulated, and makes recommendations to assist Parties in overcoming these challenges. As a final resort, this process can lead to trade suspensions. This report provides a detailed factual account of the seahorse (Hippocampus spp.) experience through the RST process. Seahorses are among the taxa for which trade is allowed but must be regulated for sustainability. Seahorses are unique in their own right, as the first fully marine fishes to go through the RST process since the Convention came into force more than 40 years ago. This report presents the methods and results of a detailed analysis of the movement of eight seahorse species through the RST process. The report underpins a policy document presented to the 17th meeting of the CITES Conference of the Parties (CoP17, September 2016) to support decision making with respect to proposed revisions to the RST process (CoP17 Inf. Doc. 53). The policy document used seahorses as a case study to draw out observations that should inform best practices in support of species conservation, and is in the process of being turned into a primary manuscript.
Entropy-Induced Collapse (EIC): Quantum State Reduction Driven by Environmental Entropy and its Implications for the Arrow of Time
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper presents a rigorous formulation of the Entropy-Induced Collapse (EIC) model, a novel framework proposing that quantum wavefunction collapse is triggered when the environmental entropy surpasses a dynamically evolving threshold. By integrating non-Markovian noise modeled via fractional Brownian motion and accounting for the effects of quantum error correction (QEC), the model offers a thermodynamically grounded mechanism for state reduction. The approach introduces a nonlinear Lindblad master equation linking entropy gradients to collapse dynamics, providing a physically testable pathway to explain the quantum-to-classical transition. Experimental protocols using superconducting qubits, trapped ion systems, and precision force measurements are proposed. As Part A of the EIC Model Series, this work focuses strictly on physical principles and testable predictions, setting aside philosophical or cognitive interpretations for future studies.

Year: 2025

description: Entropy-Induced Collapse (EIC) Model – Part B: Mathematical Foundations of Quantum Collapse Threshold and Non-Markovian Dynamics

 

Part B of the Entropy-Induced Collapse (EIC) Model series rigorously develops the mathematical foundation of the hypothesis introduced in Part A—that quantum wavefunction collapse is triggered by environmental entropy surpassing a dynamically evolving critical threshold S_{\mathrm{crit}}(t). We explicitly formalize the threshold, decomposing it into three physically motivated components: a baseline entropy S_0, a quantum error correction (QEC)-induced shift \delta(d), and entropy fluctuations modeled via fractional Brownian motion (fBm) to realistically represent non-Markovian environmental noise. Furthermore, we derive and analyze the associated nonlinear Lindblad equation describing entropy-driven collapse dynamics, ensuring compliance with fundamental constraints such as trace preservation, positivity, and no-signaling conditions.

 

This theoretical framework provides clear mathematical definitions, parameter ranges, and predictive equations, establishing a robust platform for numerical simulations (Part C) and experimental validations (Part D). Ultimately, the EIC model aims to offer a physically grounded, experimentally accessible mechanism bridging quantum measurement, thermodynamics, and the emergence of classical irreversibility.

STRUCTURAL CHANGE TOWARDS SERVICES
Creators: name: Hoelzl, Werner
Publisher: name: Zenodo
Year: 2020
Subjects: structural change, service share, manufacturing share

description: This paper examines broad patterns of structural change for a large number of countries on a global scale and for a smaller set of advanced industrialised countries over time. The findings show that structural change over the past decades followed the three-sector hypothesis. The past decades was characterised by the rise of the service sector, driven especially by business services and non-market services. But there is also substantial heterogeneity in the patterns of structural change. Together with the observation of substantial differences in productivity growth across sectors, this suggests that the direction of structural change affects growth potentials. Manufacturing sectors are declining in economic development but also the sectors with the highest productivity contributions. An analysis of determinants of structural change confirms that country competencies related to institutional quality, knowledge generation and industrial application of the new knowledge are an important driving force of structural changes towards services, but that they impact subsectors in manufacturing in a heterogeneous way. Especially the high technology manufacturing share seems not to be characterized by a tendency to decline with the development of country competencies.
Entropy-Induced Collapse (EIC) Model – Part (2) Refining the Entropy-Induced Collapse (EIC) Model for Quantum Computing: Large-Scale Quantum Error Correction, Non-Markovian Noise, and Experimental Validation
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper presents Part (2) of the Entropy-Induced Collapse (EIC) Model series, significantly refining the theoretical framework introduced in Part (1). The EIC model is a deterministic-stochastic theory describing quantum wavefunction collapse as triggered when the environmental entropy S_{\mathrm{env}}(t) surpasses a dynamically evolving critical threshold S_{\mathrm{crit}}(t). In this work, we explicitly integrate large-scale Quantum Error Correction (QEC), realistic non-Markovian fractional Brownian motion (fBm) noise, and detailed numerical validations via high-performance computing (HPC) simulations.

 

We rigorously derive and empirically validate an analytical expression for the critical entropy threshold shift \delta(d), showing a logarithmic dependence on the QEC code distance d:

 

\delta(d) = A_{\mathrm{QEC}}\ln d + B_{\mathrm{QEC}},

 

with parameters precisely determined from extensive simulations: A_{\mathrm{QEC}} = 0.232 \pm 0.052\,k_B and B_{\mathrm{QEC}} = -0.175 \pm 0.10\,k_B. Our refined model accurately predicts coherence extensions of up to approximately 80\,\mu s at code distances d \leq 11, aligning closely with experimental data from state-of-the-art superconducting quantum processors.

 

Moreover, we quantify the detrimental impact of non-Markovian fBm noise on Quantum Key Distribution (QKD) protocols, demonstrating that increasing the Hurst exponent H from 0.5 (white noise) to 0.7 (correlated noise) elevates the Quantum Bit Error Rate (QBER) by approximately 15% and reduces the secure key generation rate by 10–12%, in excellent agreement with experimental results from ID Quantique and the Micius satellite.

 

All numerical data, simulation codes, and detailed parameters are available upon request via our dedicated GitHub repository, ensuring reproducibility and facilitating future experimental validation and advancement in quantum information technologies.

Entropy-Induced Collapse (EIC) Model – Part 4: Entropy Gradients and Information-Field Mediated Interactions
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper presents Part 4 of the Entropy-Induced Collapse (EIC) model series, a rigorous theoretical framework describing quantum wavefunction collapse as a thermodynamically driven phenomenon arising from irreversible increases in environmental entropy. By employing fractional Brownian motion (fBm) to accurately model realistic, non-Markovian environmental noise, and incorporating quantum error correction (QEC), this model precisely defines conditions for collapse in terms of measurable entropy thresholds. We further introduce a novel thermodynamic scalar information field activated by local entropy gradients, exploring its interactions within standard quantum field theories and offering concrete experimental proposals utilizing MEMS gravimeters, superconducting qubit processors, and cryogenic torsion balances. The EIC framework not only provides a coherent explanation of quantum state reduction and the emergence of time’s arrow, but also opens avenues for empirical testing in laboratory conditions. All theoretical developments and experimental suggestions contained herein are explicitly intended for peaceful, non-military applications and are committed to promoting the advancement of fundamental physics and quantum technologies for the benefit of humanity.

Die Wohnsituation von Sozialhilfebeziehenden: Anspruch, Wirklichkeit und Handlungsbedarf
Creators: name: Hasler, Alina
Publisher: name: Zenodo
Year: 2020

description: Von den Klient*innen der Sozialhilfe wird erwartet, dass sie in einem günstigen Wohnraum leben. Jedoch stellt sich der Zugang zu bezahlbarem Wohnraum besonders für einkommensschwache und armutsbetroffene Personen häufig als schwierig dar. Dieser Umstand führt für Sozialarbeitende in der Sozialhilfe zu einem Spannungsverhältnis. Beim Wohnen handelt es sich um ein Grundbedürfnis und ein fundamentales Menschenrecht. Zudem ist ein adäquates Wohnen Voraussetzung für eine gesunde Entwicklung, gelingende Integration in den Arbeitsmarkt und eine gesellschaftliche Teilhabe. Da sich die Sozialhilfe zentral an armutsbetroffene Personen richtet, gewinnt die Wohnungsfrage in der Sozialen Arbeit zunehmend an Bedeutung. Entsprechend ist eine rechtlich-ethische Auseinandersetzung mit der Thematik von Interesse. In der vorliegenden Master-Thesis steht die Frage im Zentrum, was für Handlungsmöglichkeiten Sozialarbeitende hinsichtlich der Problematik Wohnen haben, mit denen sie ihren berufsethischen Auftrag wahrnehmen können. Anhand von durchgeführten Expert*inneninterviews in den sieben grössten Deutschschweizer Städten wird untersucht, ob in der Praxis eine Diskrepanz zwischen den herrschenden Rahmenbedingungen auf dem Wohnungsmarkt, den Erwartungen an die Klient*innen sowie dem berufsethischen Verständnis der Sozialen Arbeit wahrgenommen wird. Mittels den Erfragungen von bisherigen Handlungsstrategien aus der Praxis und der Erschliessung von theoretischem Fachwissen werden mögliche Handlungsmethoden und Umgangsformen für Sozialarbeitende in der direkten Klient*innenarbeit erfasst und ausgearbeitet. Wichtige Erkenntnisse sind, dass besonders Grossstädte eine starke Anspannung auf dem Wohnungsmarkt aufweisen und es für Klient*innen der Sozialhilfe häufig eine Herausforderung ist, an günstigen Wohnraum zu gelangen. Aufgrund der aktuellen Rahmenbedingungen auf dem Wohnungsmarkt und der knappen Ressourcen, sind Sozialarbeitende in der Unterstützung der Klient*innen und in ihren Handlungsmöglichkeiten jedoch eingeschränkt. Neben den bereits bestehenden Handlungsansätzen konnten mit den gewonnen Erkenntnissen weitere Handlungsmöglichkeiten für Sozialarbeitende ausgearbeitet werden, welche für die Praxis der Sozialen Arbeit nützlich sein könnten.

description: Investment Analysis is a cornerstone of the Financial Services industry. The rapid integration of advanced machine learning techniques, particularly Large Language Models (LLMs), offers opportunities to enhance the equity rating process. This paper explores the application of LLMs to generate multi-horizon stock ratings by ingesting diverse datasets. Traditional stock rating methods rely heavily on the expertise of financial analysts, and face several challenges such as data overload, inconsistencies in filings, and delayed reactions to market events. Our study addresses these issues by leveraging LLMs to improve the accuracy and consistency of stock ratings. Additionally, we assess the efficacy of using different data modalities with LLMs for the financial domain.
 We utilize varied datasets comprising fundamental financial, market, and news data from January 2022 to June 2024, along with GPT-4-32k (v0613) (with a training cutoff in Sep. 2021 to prevent information leakage). Our results show that our benchmark method outperforms traditional stock rating methods when assessed by forward returns, specially when incorporating financial fundamentals. While integrating news data improves short-term performance, substituting detailed news summaries with sentiment scores reduces token use without loss of performance. In many cases, omitting news data entirely enhances performance by reducing bias.
 Our research shows that LLMs can be leveraged to effectively utilize large amounts of multimodal financial data, as showcased by their effectiveness at the stock rating prediction task. Our work provides a reproducible and efficient framework for generating accurate stock ratings, serving as a cost-effective alternative to traditional methods. Future work will extend to longer timeframes, incorporate diverse data, and utilize newer models for enhanced insights.

Part 9: Entropy-Induced Collapse and the Emergence of Temporal Directionality: A Quantum-Informational Approach
Creators: name: Takao Koizumi
Publisher: name: Zenodo
Year: 2025

description: This paper (Part 9 of the Entropy-Induced Collapse (EIC) Model series) introduces a theoretical framework connecting entropy-driven quantum wavefunction collapse to the emergence of the arrow of time and subjective temporal experience. By proposing that stochastic quantum state reductions triggered by irreversible environmental entropy increases establish a sequence of discrete conscious moments, the paper quantitatively explains how macroscopic time asymmetry emerges from fundamentally time-symmetric quantum laws. The formalism integrates nonlinear Lindblad dynamics, quantum Fisher information, and a higher-dimensional information field, providing a novel interdisciplinary link between physics, information theory, and consciousness studies. The manuscript also outlines experimental strategies combining quantum technologies and neurophysiological methods for empirical verification, highlighting significant implications for theoretical physics, cognitive science, and philosophy of time.
Rat in the ranks: David Hicks and the representations of justice and threat in the 'War on Terror'
Creators: name: Bossio, Diana
Publisher: name: Swinburne
Year: 2024

description: In December 2001, the Australian 'Taliban fighter' David Hicks was captured by the Northern Alliance in Afghanistan. Hicks was subsequently transferred to Guantanamo Bay by the US military, where he has remained for five years awaiting a military commission trial that has been roundly condemned for its partisan approach to justice. David Hicks' imprisonment as an alleged 'terrorist' saw him branded by both government officials and the media as a 'rat in the ranks': a traitor to Australia's role in the Coalition of the Willing and the embodiment of Australia's 'new' insecurity about the threat in 'our own backyards'. Indeed, governmental response to Hicks' imprisonment has focussed on themes of 'otherness', where the allegations of Hicks' terrorist actions have served as legitimation for the apparent circumvention of his legal and civil rights. Nonetheless, subsequent media reportage has become increasingly ambivalent towards both US and Australian approaches to justice, allowing more discursive space for dissenting viewpoints in the public arena. By analysing various representations of Hicks by Australian governmental authorities and newspaper media, this paper examines the discourse of the 'terrorist threat' in an age of insecurity and how this discourse manipulates traditional understandings of citizenship and justice.
Enhancing the clinical reflective capacities of nursing students
Creators: name: Andersen, Elizabeth
Publisher: name: The University of British Columbia
Year: 2017

description: The purpose of clinical practicums is to help nursing students learn from real clinical experiences. In clinical settings, nursing instructors set-aside time at the end of each clinical day for reflective, debriefing discussions that are designed to draw the students’ attention to relevant information and help them understand their beliefs and experiences. The students’ competence and decision-making skills are enhanced when they are able to reflect on critical incidents or everyday practice events. It is sometimes difficult, however, for instructors to engage students meaningfully in discussions and promote reflection when students are fatigued. In this article, I argue that it is possible to refresh, support, and inspire undergraduate nursing students by engaging them in an activity designed to distract them and occupy their conscious attention, so that their more divergent and less accessible ideas are allowed to surface. Less accessible ideas are associated with the default network; regions in the brain that are most active when the brain is allowed to rest and wander. Congruent with the middle range theory of comfort, a distracting activity will provide comfort to students who are fatigued and/or distressed, and at the same time, will enhance their reflective capacities. A distracting activity that is enjoyable, not too demanding, and can be sustained for more than just a few minutes works best for idea generation and reflection.

description: The coil-to-globule transition of poly(N-isopropylacrylamide) (PNIPAM) microgel particles suspended in water has been investigated in situ as a function of heating and cooling rate with four optical process analytical technologies (PAT), sensitive to structural changes of the polymer. Photon Density Wave (PDW) spectroscopy, Focused Beam Reflectance Measurements (FBRM), turbidity measurements, and Particle Vision Microscope (PVM) measurements are found to be powerful tools for the monitoring of the temperature-dependent transition of such thermo-responsive polymers. These in-line technologies allow for monitoring of either the reduced scattering coefficient and the absorption coefficient, the chord length distribution, the reflected intensities, or the relative backscatter index via in-process imaging, respectively. Varying heating and cooling rates result in rate-dependent lower critical solution temperatures (LCST), with different impact of cooling and heating. Particularly, the data obtained by PDW spectroscopy can be used to estimate the thermodynamic transition temperature of PNIPAM for infinitesimal heating or cooling rates. In addition, an inverse hysteresis and a reversible building of micrometer-sized agglomerates are observed for the PNIPAM transition process.

description: An efficient electrocatalytic biosensor for sulfite detection was developed by co-immobilizing sulfite oxidase and cytochrome c with polyaniline sulfonic acid in a layer-by-layer assembly. QCM, UV-Vis spectroscopy and cyclic voltammetry revealed increasing loading of electrochemically active protein with the formation of multilayers. The sensor operates reagentless at low working potential. A catalytic oxidation current was detected in the presence of sulfite at the modified gold electrode, polarized at +0.1 V ( vs. Ag/AgCl 1 M KCl). The stability of the biosensor performance was characterized and optimized. A 17-bilayer electrode has a linear range between 1 and 60 mu M sulfite with a sensitivity of 2.19 mA M-1 sulfite and a response time of 2 min. The electrode retained a stable response for 3 days with a serial reproducibility of 3.8% and lost 20% of sensitivity after 5 days of operation. It is possible to store the sensor in a dry state for more than 2 months. The multilayer electrode was used for determination of sulfite in unspiked and spiked samples of red and white wine. The recovery and the specificity of the signals were evaluated for each sample.

description: Objective: This study evaluated the 15 Chinese renal nutrition handouts developed at Providence Health Care (PHC) by using the Suitability Assessment of Material (SAM) tool. Methods: A quantitative, non-experimental survey design was used to assess overall suitability, content, literacy demand, graphics, layout and typography, learning stimulation/motivation, and cultural appropriateness of the handouts. The evaluation was done using the SAM tool. Results: Eight of the 15 handouts were found to be superior and seven adequate in overall suitability. Subscale scores identified three areas of relative weakness – lack of inclusion of summary or review, high reading grade level, and the lack of use of interactive learning stimulation. Conclusions and Implications: This systematic evaluation found that all of the 15 handouts were suitable overall. A few relative weaknesses were identified and they will be addressed at the next revision. This study also confirmed that the SAM is a feasible tool to evaluate patient education materials.

description: Background Medium- to large-scale expression profiling using quantitative polymerase chain reaction (qPCR) assays are becoming increasingly important in genomics research. A major bottleneck in experiment preparation is the design of specific primer pairs, where researchers have to make several informed choices, often outside their area of expertise. Using currently available primer design tools, several interactive decisions have to be made, resulting in lengthy design processes with varying qualities of the assays. Results Here we present QuantPrime, an intuitive and user-friendly, fully automated tool for primer pair design in small- to large-scale qPCR analyses. QuantPrime can be used online through the internet http://www.quantprime.de/ or on a local computer after download; it offers design and specificity checking with highly customizable parameters and is ready to use with many publicly available transcriptomes of important higher eukaryotic model organisms and plant crops (currently 295 species in total), while benefiting from exon-intron border and alternative splice variant information in available genome annotations. Experimental results with the model plant Arabidopsis thaliana, the crop Hordeum vulgare and the model green alga Chlamydomonas reinhardtii show success rates of designed primer pairs exceeding 96%. Conclusion QuantPrime constitutes a flexible, fully automated web application for reliable primer design for use in larger qPCR experiments, as proven by experimental data. The flexible framework is also open for simple use in other quantification applications, such as hydrolyzation probe design for qPCR and oligonucleotide probe design for quantitative in situ hybridization. Future suggestions made by users can be easily implemented, thus allowing QuantPrime to be developed into a broad-range platform for the design of RNA expression assays.
