description: We suggest a method to generate coherent short pulses by generating a frequency comb using lasing without inversion in the transient regime. We use a universal method to study the propagation of a pulse in various spectral regions through an active medium that is strongly driven on a low-frequency transition on a time scale shorter than the decoherence time. The results show gain on the sidebands at different modes can be produced even if there is no initial population inversion prepared. Besides the production of ultra-short pulse this frequency comb may have applications towards making short-wavelength or Tera-hertz lasers.
title: Psychomotorische Gesundheitsförderung und Stressbewältigung im Erwachsenenalter

Year: 2023

description: Das körperliche und geistige Wohlbefinden spielt besonders im Erwachsenenalter eine bedeutsame Rolle. Alltägliche Anforderungen führen oftmals zur Überforderung und bewirken das Gefühl von Stress, das über einen längeren Zeitraum ein gesundheitliches Risiko darstellen kann. Die vorliegende Arbeit beschäftigt sich mit den negativen Auswirkungen von Stress auf die Gesundheit. Die Begrifflichkeit der Gesundheit wird geklärt sowie die Bedeutsamkeit des Wechselspiels von psychischen und physischen Faktoren. Die verschiedenen Theorien des Gesundheitsverhaltens zeigen auf, wie das eigene Verhalten den Prozess der Gesundheit, als auch den der Krankheit beeinflussen kann. Es wird dargestellt, wodurch Stress verursacht werden kann, wie sich Stress äußert und welche Stresstheorien es gibt. Des Weiteren werden die Möglichkeiten der Stressbewältigung dargestellt, die in engem Zusammenhang mit den wesentlichen Faktoren der Psychomotorik stehen. Um ein Bewusstsein für die Psychomotorik schaffen zu können, werden sowohl die Inhalte und Ziele als auch die zentralen Begriffe der Psychomotorik erklärt. Darauf folgend wird das psychomotorische Konzept als eine Strategie zur Stressbewältigung dargestellt. Im Anschluss werden die zentralen Aspekte der psychomotorischen Gesundheitsförderung im Erwachsenenalter aufgezeigt, um in weiterer Folge die Methode der Stressbewältigung durch Psychomotorik zu klären. Dabei werden die methodischen Prinzipien der psychomotorischen Begleitung von Erwachsenen herausgearbeitet. Die Zusammenhänge der theoretischen Konstrukte lassen darauf schließen, dass Psychomotorik als eine Strategie der Stressbewältigung im Erwachsenenalter eingesetzt werden kann.
The evolution of carrying capacity in constrained and expanding tumour cell populations

Subjects: subject: Populations and Evolution (q-bio.PE)

description: Cancer cells are known to modify their micro-environment such that it can sustain a larger population, or, in ecological terms, they construct a niche which increases the carrying capacity of the population. It has however been argued that niche construction, which benefits all cells in the tumour, would be selected against since cheaters could reap the benefits without paying the cost. We have investigated the impact of niche specificity on tumour evolution using an individual based model of breast tumour growth, in which the carrying capacity of each cell consists of two components: an intrinsic, subclone-specific part and a contribution from all neighbouring cells. Analysis of the model shows that the ability of a mutant to invade a resident population depends strongly on the specificity. When specificity is low selection is mostly on growth rate, while high specificity shifts selection towards increased carrying capacity. Further, we show that the long-term evolution of the system can be predicted using adaptive dynamics. By comparing the results from a spatially structured vs.\ well-mixed population we show that spatial structure restores selection for carrying capacity even at zero specificity, which a poses solution to the niche construction dilemma. Lastly, we show that an expanding population exhibits spatially variable selection pressure, where cells at the leading edge exhibit higher growth rate and lower carrying capacity than those at the centre of the tumour.
description: Major revisions compared to previous version. The paper is now aimed at tumour modelling. We now start out with an agent-based model for which we derive a mean-field ODE-model. The ODE-model is further analysed using the theory of adaptive dynamics
Safety first portfolio choice based on financial and sustainability returns

description: This paper lays the mathematical foundations of the notion of an investment's sustainability return and investigates three different models of portfolio selection with probabilistic constraints for safety first investors caring about the financial and the sustainability consequences of their investments. The discussion of these chance-constrained programming problems for stochastic and deterministic sustainability returns includes theoretical results especially on the existence of a unique solution under certain conditions, an illustrating example, and a computational time analysis. Furthermore, we conclude that a simple convex combination of financial and sustainability returns - yielding a new univariate decision variable - is not sufficiently general.

description: In a recent publication [Phys. Rev. Lett. 111, 143602] we have shown using a QED approach that, in the presence of a magnetic field, the quantum vacuum coupled to a chiral molecule provides a kinetic momentum directed along the magnetic field. Here we explain the physical mechanisms which operate in the transfer of momentum from the vacuum to the molecule. We show that the variation of the molecular kinetic energy originates from the magnetic energy associated with the vacuum correction to the magnetization of the molecule. We carry out a semiclassical calculation of the vacuum momentum and compare the result with the QED calculation.

description: We introduce and study a novel tensor approach for fast and accurate assembled summation of a large number of lattice-allocated potentials represented on 3D $N\times N \times N$ grid with the computational requirements only \emph{weakly dependent} on the number of summed potentials. It is based on the assembled low-rank canonical tensor representations of the collected potentials using pointwise sums of shifted canonical vectors representing the single generating function, say the Newton kernel. For a sum of electrostatic potentials over $L\times L \times L$ lattice embedded in a box the required storage scales linearly in the 1D grid-size, $O(N )$, while the numerical cost is estimated by $O(N L)$. For periodic boundary conditions, the storage demand remains proportional to the 1D grid-size of a unit cell, $n=N/L$, while the numerical cost reduces to $O(N)$, that outperforms the FFT-based Ewald-type summation algorithms of complexity $O(N^3 \log N)$. The complexity in the grid parameter $N$ can be reduced even to the logarithmic scale $O(\log N)$ by using data-sparse representation of canonical $N$-vectors via the quantics tensor approximation. For justification, we prove an upper bound on the quantics ranks for the canonical vectors in the overall lattice sum. The presented approach is beneficial in applications which require further functional calculus with the lattice potential, say, scalar product with a function, integration or differentiation, which can be performed easily in tensor arithmetics on large 3D grids with 1D cost. Numerical tests illustrate the performance of the tensor summation method and confirm the estimated bounds on the tensor ranks.

description: The new definition of the energy dependence for the level density parameter including collective effects depends strongly on the semi-classical approach. For this method, defining an accurate single-particle potential is of great importance. The effect of the single-particle potential terms, which are central, spin-orbit, harmonic oscillator, Woods-Saxon and Coulomb potential, both for spherical and deformed cases, on the level density parameter was investigated by examining the local success of the global parameterizations of eight different combinations of these terms. Among these combinations, the sum of the central, spin-orbit, harmonic oscillator and Coulomb potentials, gives the most accurate predictions compared with experimental data. The local selections of the global parameterizations show that the single-particle models, which are based on Woods-Saxon potential as the main term, are more suitable candidates than the models based on harmonic oscillator potential to extrapolate away far from stability. Also it can be concluded that the contribution of the Coulomb interaction, both around the closed and open shells is not neglectable.

Navigating Trauma: Impacts on Memory and Cognitive Resilience

Year: 2024
Subjects: Trauma, Memory, Cognitive Functioning, Therapeutic Interventions, Neuropsychological Tests & PTSD

description: This study investigates the impact of trauma on memory and cognitive functioning, with a focus on the implications for therapeutic interventions. Using a mixed-methods design, the research was conducted in clinical settings involving a sample of 50 individuals who have experienced trauma and 50 who have not, out of a total population of 100 participants. Quantitative data were collected through standardized neuropsychological tests, while qualitative insights were obtained from semi-structured interviews. The results indicate that there is no significant difference in memory performance between individuals who have experienced trauma and those who have not (r = -0.21, p = 0.08), suggesting a weak negative correlation that is not statistically significant. Similarly, the study found no significant relationship between the severity of trauma experienced and cognitive functioning (r = 0.03, p = 0.78), indicating that trauma severity does not appear to influence cognitive functioning in the sample. However, the study did find a significant positive correlation between therapeutic interventions and improved memory and cognitive functioning (r = 0.52, p < 0.001). This suggests that therapeutic interventions designed to address trauma are associated with enhanced cognitive outcomes, highlighting their efficacy in improving memory and cognitive functioning among affected individuals. These findings underscore the importance of therapeutic interventions in supporting trauma survivors, facilitating adaptive cognitive restructuring and promoting psychological well-being

description: We show that the use of momentum-space optical interferometry, which avoids any spatial overlap between two parts of a macroscopic quantum state, presents a unique way to study coherence phenomena in polariton condensates. In this way, we address the longstanding question in quantum mechanics: "\emph{Do two components of a condensate, which have never seen each other, possess a definitive phase?}" [P. W. Anderson, \emph{Basic Notions of Condensed Matter Physics} (Benjamin, 1984)]. A positive answer to this question is experimentally obtained here for light-matter condensates, created under precise symmetry conditions, in semiconductor microcavities taking advantage of the direct relation between the angle of emission and the in-plane momentum of polaritons.

description: An experiment was conducted to assess sleep and circadian regulation in an orbiting spacecraft. In orbit the weakened influence of 24-h zeitgebers could result in delayed circadian phases with the possibility of a transition to free-running circadian rhythms. This and the specific stressors of a space mission may lead to changes in ultradian sleep regulation and in reduced sleep quantity and quality. During the mission sleep was recorded polygraphically on tape, as was body temperature. Daytime alertness was rated subjectively by a mood questionnaire. For comparison the same parameters were measured during a baseline period preceding the space mission. The circadian rhythms of body temperature and alertness were found to be delayed in space compared to baseline. This may mark a phase shift or the transition to a circadian state of free-run. Sleep was shorter and more disturbed. The structure of sleep was significantly altered. In space REM latency was shorter, there was less REM sleep in the second non-REM/REM cycle, and slow-wave sleep was redistributed from the first to the second cycle. The self-assessed mood resembled sleep disturbances and adaptation to the space environment. Reduced sleep quality and quantity are likely to result in fatigue and lower daytime performance. Countermeasures should be adopted to improve sleep of astronauts.

description: The ability to compare complex systems can provide new insight into the fundamental nature of the processes captured in ways that are otherwise inaccessible to observation. Here, we introduce the $n$-tangle method to directly compare two networks for structural similarity, based on the distribution of edge density in network subgraphs. We demonstrate that this method can efficiently introduce comparative analysis into network science and opens the road for many new applications. For example, we show how the construction of a phylogenetic tree across animal taxa according to their social structure can reveal commonalities in the behavioral ecology of the populations, or how students create similar networks according to the University size. Our method can be expanded to study a multitude of additional properties, such as network classification, changes during time evolution, convergence of growth models, and detection of structural changes during damage.

description: Absence of information on the health effects of the intake of a mixture of methylated spirit and carbonated cola drink affects decisions on its use. The campaign for the disuse of the substances recently being abused by young people across Nigeria shall be baseless without empirical evidence to validate such clamours. This study is an attempt to provide primary data on how some of these novel mixtures impact the body. It aims to determine the effects of a mixture of methylated spirit and a carbonated cola drink on the lipid profile of male wistar rats as a means of assessing its health impact. Male wistar rats were obtained from the animal house of the Department of Biochemistry, University of Benin, Edo state, Nigeria. Methylated spirit and carbonated cola drinks were purchased from Otuoke Pharmacy, Otuoke, Bayelsa state and used for the research. Methylated spirit (50ml) was added to 50ml of cola drink in a beaker to obtain 100ml of the mixture. The animals were grouped into 3: A, B and C with seven animals in each group. A single dose of 0.1ml of the mixture were orally administered to those in group A and 0.2ml to those in group B using plastic oral intubation and gavage tube. Those in group C where orally administered 1 ml of distilled water and served as the control. The concentrations of total cholesterol, high density lipoprotein, low density lipoprotein, triglyceride and very low density lipoprotein were analyzed using semi-automated biochemistry analyzer with standard reagent kits. The result of the investigation reveals that intake of the mixture increased the mean levels of total cholesterol (3.774± 0.82𝑚𝑚𝑜𝑙/ 𝐿), triglyceride (2.026± 0.42𝑚𝑚𝑜𝑙/𝐿), high density lipoprotein (1.468± 0.25𝑚𝑚𝑜𝑙/𝐿), low density lipoprotein (1.385± 0.38𝑚𝑚𝑜𝑙/𝐿), very low density lipoprotein (0.9205± 0.19𝑚𝑚𝑜𝑙/𝐿) for group A and total cholesterol (2.782± 0.03𝑚𝑚𝑜𝑙/ 𝐿), triglyceride (1.450± 0.68𝑚𝑚𝑜𝑙/𝐿), high density lipoprotein (1.043± 0.17𝑚𝑚𝑜𝑙/𝐿), low density lipoprotein (1.080± 0.16𝑚𝑚𝑜𝑙/𝐿), very low density lipoprotein (0.659± 0.31𝑚𝑚𝑜𝑙/ 𝐿) for group B when compared to the control total cholesterol (4.671± 0.13𝑚𝑚𝑜𝑙/ 𝐿), triglyceride (0.6160± 0.10𝑚𝑚𝑜𝑙/𝐿), high density lipoprotein (1.084± 0.01𝑚𝑚𝑜𝑙/𝐿), low density lipoprotein (3.321± 0.05𝑚𝑚𝑜𝑙/𝐿), very low density lipoprotein

(0.2910± 0.03𝑚𝑚𝑜𝑙/𝐿). The observed altered the lipid profiles in the experimental subjects may initiate further metabolic changes as high lipid levels have been associated with weight gain, obesity and atherosclerosis. Although alcohol is a substance of complex physiological effects that vary according to gender, age, race, body weight and consumption patterns, methanol as used in the mixture is not advisable, because its continual consumption will result in the development of cardiovascular diseases in abusers

description: Most deep learning models for computational imaging regress a single reconstructed image. In practice, however, ill-posedness, nonlinearity, model mismatch, and noise often conspire to make such point estimates misleading or insufficient. The Bayesian approach models images and (noisy) measurements as jointly distributed random vectors and aims to approximate the posterior distribution of unknowns. Recent variational inference methods based on conditional normalizing flows are a promising alternative to traditional MCMC methods, but they come with drawbacks: excessive memory and compute demands for moderate to high resolution images and underwhelming performance on hard nonlinear problems. In this work, we propose C-Trumpets -- conditional injective flows specifically designed for imaging problems, which greatly diminish these challenges. Injectivity reduces memory footprint and training time while low-dimensional latent space together with architectural innovations like fixed-volume-change layers and skip-connection revnet layers, C-Trumpets outperform regular conditional flow models on a variety of imaging and image restoration tasks, including limited-view CT and nonlinear inverse scattering, with a lower compute and memory budget. C-Trumpets enable fast approximation of point estimates like MMSE or MAP as well as physically-meaningful uncertainty quantification.

description: This working paper was prepared as a report for the German Federal Ministry of Food and Agriculture. The content of the paper is to present the current state of affairs and development trends of the regulations on prices in the supply relationships for milk-producing farms and the first receiving hand, i.e. the dairies. The aim is to identify possible levers that could help to shape pricing more in the interest of milk producers. The question of how, against this background, examples of rules for an application of Article 148 (4) of the CMO in conformity with EU law could look was not addressed for the time being. This working paper is essentially divided into three parts. The first part describes the initial situation in the form of a classification of the current situation of supplier relations and possible requirements for action from a scientific point of view. The second part presents the methodology, the concept and the results of the interviews with experts of the dairy industry. In the third part, the findings from the more theoretical approach of the first part are combined with the results of the interviews of the second part and conclusions for possible recommendations for action are derived. The background information and the interviews conducted provide an initial overview of the supply relationships between milk producers and dairies in Germany. Furthermore, the results show differences and overlaps between the supply relationships of private and cooperative dairies with their milk producers. In order to be able to better classify the results for the entire dairy sector and to include the individual opinions, ideas and suggestions in the discussion, further interviews should be conducted with other groups of experts. These include associations, representatives of the German retail trade and milk producers of different sizes.

description: We introduce a rate formalism to treat classically forbidden electron transport through a quantum dot (cotunneling) in the presence of a coupled measurement device. We demonstrate this formalism for a toy model case of cotunneling through a single-level dot while being coupled to a strongly pinched-off quantum point contact (QPC). We find that the detector generates three types of back-action: the measurement collapses the coherent transport through the virtual state, but at the same time allows for QPC-assisted incoherent transport, and widens the dot level. Last, we obtain the measured cotunneling time from the cross correlation between dot and QPC currents.

description: The electronic transition energies of the Mx[Pt²⁺(CN)₄]•mH₂O compounds, crystallizing in columnar structures, depend strongly on the Pt-Pt distance R in the direction of the columns. R can be varied by substituting M and/or by application of high pressure. Using three different compounds {Na₂[Pt(CN)₄]•3H₂O, Ca[Pt(CN)₄]•5H₂O, Mg[Pt(CN)₄]•7H₂O} and applying hydrostatic pressures up to 38 kbar it is possible to adjust the emission energy continously from 3.3 to about 1.35 eV. The pressure-induced energy shift is unusually large with values between -320 and -140 cm⁻¹/kbar.

description: Le présent article examine l'interaction entre les principes de la corporate gouvernance et la performance des entreprises cotées en bourse. La corporate gouvernance est un vaste domaine qui englobe un ensemble de structures, de politiques et de processus conçus pour régir le fonctionnement et la supervision des organisations. Ces principes visent à établir un cadre de gestion qui favorise la responsabilité, la transparence, l'éthique et l'intégrité au sein de l'entreprise. Cet article repose sur une analyse approfondie de la littérature existante portant sur le lien entre la corporate gouvernance et la performance des entreprises cotées en bourse. Des recherches précédentes ont déjà avancé que la mise en place d'une bonne corporate gouvernance et de ses principes peut favoriser la création de valeur et l'amélioration des performances des entreprises. L'objectif de cet article est de présenter un cadre conceptuel global qui intègre les concepts de corporate gouvernance et de performance. Il offre également une revue de la littérature et propose un modèle conceptuel de recherche explorant la relation entre les principes de corporate gouvernance et la performance des entreprises cotées en bourse.

description: It is now well acknowledged that napping constitutes an inherent component of the human circadian system. To date, however, few studies have examined the effects of spontaneous napping on human free-running rhythms. This study investigated the free-running circadian periods of rest/activity and body core temperature in a group of young subjects who were permitted to nap during their time in isolation. Based on the frequency of self-reported sleep bouts, subjects were classified as Nappers or Nonnappers. Nappers exhibited free-running rhythms in both rest/activity and body core temperature that were not significantly different from 24 hours. Nappers showed a tendency for shorter free-running periods in both variables, when compared with Nonnappers. These findings emphasize the need for careful reassessment of data obtained from traditional free-run protocols.

description: The CMB anisotropy at $\ell\lsim 60$ seems to have some special features which include (i) a dipole modulation and (ii) a decrease in power. It is known that both of these effects can be generated if a curvaton-type field has a super-horizon perturbation. It is also known that this will generate non-gaussianity $\fnl$ in the same range of $\ell$, whose magnitude has a lower bound coming from the magnitude of the observed CMB quadrupole. I revisit that bound in the present paper, and point out that it may or may not be compatible with current data which should therefore be re-analysed.

description: The main objective of this study is to identify the Challenges and Opportunities of Implementing various Electronic-Payment Projects in the Commercial Bank of Ethiopia: taking Point of Sale (POS) Terminal as a case study. Mixed research design was employed and primary data was collected through questionnaires and semi-structured interviews from employees and customers of the bank and analyzed using quantitative (statistical) and qualitative methods. The finding of this study reveals that the most challenging factor to the implementation of POS terminal is network failure. Organizational factors such as lack of employees' knowledge to answer customers' questions related to POS terminal, low support and follow up, lack of coordination and cooperation between different units of the bank viz. branches, districts, and E-payment process are considered as challenges in implementing POS terminal system. Moreover, payment mode factors such as double debit of accounts for single transaction due to connectivity failures, deduction of customers account for failed transactions are amongst the challenges identified by the study. Despite the aforementioned and other challenges, the study showed that Growing acceptance of POS terminal, the Business growth of the bank, NBE's policy direction that enforce banks to adopt technological innovation, change in the society life style i.e. the ongoing digital and technology revolution are some of the major opportunities identified by the study.
title: Haftung von Diensteanbieter:innen
Creators: name: Raffaseder, Franz

description: Bereits das bestehende Haftungsregime der §§ 13 ff ECG bietet in seiner Ausgestaltung durch die Rsp durchaus weitreichende Möglichkeiten, gegen Diensteanbieter:innen vorzugehen. Zwar können infolge der auf Grundlage der EC-RL normierten Haftungsbeschränkungen nicht sämtliche Rechtsverletzungen jedweder Art schadenersatzrechtlich geahndet werden, allerdings besteht ein weitergehender Rechtsschutz durch Unterlassungsansprüche. Im Hinblick auf das Kollisions- und Verfahrensrecht bestehen sowohl im Unionsrecht als auch im innerstaatlichen Recht vielfältige Anknüpfungspunkte, um Ansprüche vor österreichischen Gerichten geltend zu machen und Haftungsfragen nach österreichischem Recht zu beurteilen. Durch die Erweiterung des Marktortprinzips im DSA sollte es in Hinkunft allerdings noch einfacher sein, ausländische Diensteanbieter:innen für Rechtsverletzungen zur Verantwortung zu ziehen. Dass die Haftungsbeschränkungen der EC-RL über 20 Jahre später inhaltlich quasi unverändert in den DSA übernommen wurden, ist in Anbetracht der Schnelligkeit, mit der es gegenwärtig auf europäischer Ebene in unterschiedlichster Rechtsgebieten zu – mitunter weitreichenden – Novellierungen kommt, als überaus bemerkenswert zu bezeichnen. Bedenkt man weiters den rasanten technischen Fortschritt seit In-Kraft-Treten der EC-RL und die gegensätzlichen Interessen, die in den Gesetzgebungsprozess auf europäischer Ebene einfließen – jene der Verbraucher:innen einerseits und jene der Diensteanieter:innen andererseits –, zeigt sich, dass sich es sich bei den Haftungsbeschränkungen von EC-RL/DSA um durchaus ausgewogene Regelungen handelt, die den Herausforderungen der Praxis offenbar gerecht werden. Damit stehen die Aussichten gut, dass diese Bestimmungen auch die nächsten Jahrzehnte überdauern und das mit dem DSA verfolgte Ziel zu erreichen helfen werden, das Online-Umfeld auch in Hinkunft möglichst „sicher, berechenbar und vertrauenswürdig“ zu machen.
Local boundary conditions for NMR-relaxation in digitized porous media

description: We narrow the gap between simulations of nuclear magnetic resonance dynamics on digital domains (such as CT-images) and measurements in D-dimensional porous media. We point out with two basic domains, the ball and the cube in D dimensions, that due to a digital uncertainty in representing the real pore surfaces of dimension D-1, there is a systematic error in simulated dynamics. We then reduce this error by introducing local Robin boundary conditions.

description: A robust worldwide air-transportation network (WAN) is one that minimizes the number of stranded passengers under a sequence of airport closures. Building on top of this realistic example, here we address how spatial network robustness can profit from cooperation between local actors. We swap a series of links within a certain distance, a cooperation range, while following typical constraints of spatially embedded networks. We find that the network robustness is only improved above a critical cooperation range. Such improvement can be described in the framework of a continuum transition, where the critical exponents depend on the spatial correlation of connected nodes. For the WAN we show that, except for Australia, all continental networks fall into the same universality class. Practical implications of this result are also discussed.
Forced splitting of human sleep in free-running rhythms

description: The assumption of polyphasic sleep/wake regulation is based on the occurrence of nap-sleep at specific phase positions in the circadian cycle. Further support would be the split of the normal long major sleep episode into shorter components. Evidence for this hypothesis comes from the discovery of bimodal distribution in sleep duration. An experimental approach to test this hypothesis has been carried out by restricting sleep duration in free-running rhythms. The outcome was a biphasic distribution of sleep within a circadian cycle with sections of dissociation and synchronization of the two sleep blocks. The results show similarities with 'splitting', a phenomenon which has been found in animal studies. The relatively short duration of the different sections as well as the asymmetric distribution of the two sleep blocks in the circadian cycle leads to the assumption of a splitting of the major sleep episode and not of the circadian rhythm. Sleep split into two, relatively short sleep episodes of comparable duration contrasts with napping, which is characterized by an extra sleep episode in addition to the long major sleep.
Micromechanical study of the dilatational response of porous solids with pressure-insensitive matrix displaying tension-compression asymmetry

description: In this paper, the dilatational response of porous solids with pressure-insensitive matrix displaying strength differential (SD) effects is investigated. To this end, micromechanical finite-element analyses of three-dimensional unit cells are carried out. The matrix behavior is governed by the isotropic form of Cazacu et al. (2006) criterion that accounts for SD effects through a parameter k. Simulation results are presented for axisymmetric tensile loadings corresponding to fixed values of the stress triaxiality for the two possible values of the Lode parameter, LP. For moderate and high stress triaxialities, it is shown that for materials for which the matrix tensile strength is larger than its compressive strength (k > 0), under tensile loadings corresponding at LP=1 the void growth rate is much faster than in the case of tensile loadings at LP=-1. The opposite holds true for materials with matrix tensile strength lower than its compressive strength (k< 0). This drastic difference in porosity evolution is explained by the distribution of the local plastic strain and stresses, which are markedly different than in a von Mises material (i.e. no SD effects of the matrix).

description: In the face of a homelessness crisis in the state of Victoria, the Legislative Council Legal and Social Issues Committee of the Parliament of Victoria recommended in March 2021 that the State include a right to housing within the Charter of Human Rights and Responsibilities Act (2006) (Vic). But what should such a right to housing look like, and what will it protect within its scope? This article analyses three examples of a right to housing that Victoria might take as inspiration: the International Covenant on Economic, Social and Cultural Rights; the European Social Charter (Revised); and the Constitution of the Republic of South Africa Act 1996 (South Africa). It turns specific attention to the scope of the right; the interplay of its normative content and state obligations; and its interpretation. I argue that it is crucial to appreciate the interpretation of the right in each of these jurisdictions, in order to understand the potential consequences entailed in adopting a specific model for a right to housing. The article assesses the strengths, weaknesses and suitability of each potential right, to inform a robust discussion over the shape a right to housing could take in Victoria, and by extension, Australia.
