title: A Holistic Approach: Personalizing Large Semi-Public Displays for Intercultural Groups
Creators: name: Stojko, Laura
Publisher: name: Gesellschaft für Informatik e.V.
Year: 2024

description: Personalizing user interfaces increases usability and user experience. Focusing on large-semi public displays as technology that shares its user interface with diverse people raises the question of whether and how personalization can occur and what kind of user involvement can be expected. Considering cultural design preferences for personalization is especially interesting, as it has been shown to increase usability within single-user applications. Therefore, this paper summarizes and clarifies the potential of personalization and user involvement in combination with large semi-public displays, which should be used by several users, considering cultural design preferences, and describes the challenges in this process. As a result, 15 culturally relevant user interface aspects were identified and assigned to personalization paradigms for a holistic analysis of their potential. This result provides a general basis for cultural adaptations and discussions about user involvement in the design process of large semi-public displays.

description: Between 2015 and 2020 we participated in a joint research project to explore technological interventions fostering participation of older adults in urban spaces. UrbanLife+ involved multi-year qualitative and quantitative empirical work on obstacles faced by people aged 65 and up living in cities. This brief retrospective does not recap the previously published results of the project, but summarizes methodological and organizational insights as well as pragmatic experiences gathered during its runtime that have not yet been discussed publicly. We focus on aspects relevant for future urban technology projects aiming for accessibility and inclusivity. These include issues navigating interdisciplinary design teams, conducting questionnaire studies with older adults, maintaining participatory design principles with geographically distributed teams, and conducting empirical evaluations during the COVID-19 pandemic.

However, individualized consciousness can serve as a useful metaphor for designing human-computer interaction.
Competitiveness of the Indian Manufacturing Sector: An Inter-Industry Perspective
Creators: name: Sahoo, Pradipta Kumar
Publisher: name: Swinburne
Year: 2024

description: Competitiveness is a concept commonly used in economics, ranging from the analysis of firms to the analysis of countries. This study examines the competitiveness of the Indian manufacturing sector using the composite index approach. The result reveals that capital-intensive industries are more competitive than labor-intensive industries and foreign-owned firms are more competitive than domestic firms. The determinants of competitiveness derived from the FGLS model indicate that the firms’ external factors such as ICT and infrastructure positively affect firms’ competitiveness. Finally, the empirical analysis of the study supports the “learning by exporting” hypothesis from export to competitiveness in the Indian manufacturing sector.

description: Il mito della Frontiera americana nasce tra il diciottesimo e il diciannovesimo secolo. Prima di essere un ideale e una teoria politica, la Frontiera è un genere letterario, che si sviluppa dalla scrittura dei pionieri di origine europea sulla terra dell’Ovest americano. Se il mito della Frontiera sopravvive alla frontiera fisica, così non è per il genere letterario ad esso associato; terminata la stagione delle grandi esplorazioni, con Mark Twain si chiude la stagione epica del racconto di derivazione orale e si apre un nuova età per la narrativa americana.

The Missing Measure of Loneliness: A Case for Including Neededness in Loneliness Scales

description: Prominent tools used to measure loneliness such as the UCLA Scale and DJGS include no items related to being needed, i.e., neededness. More recent scales such as the DLS and SELSA do include items on neededness, but only within their romantic loneliness subscales. This paper proposes that new iterations of loneliness scales should include in all subscales two items on neededness: (a) whether a person feels important to someone else and (b) whether that person has good ways to serve others’ well-being. The paper surveys cognate studies that do not rely on loneliness scales but establish a link between neededness and feelings of social connection. It then highlights ways in which neededness items would improve the ability of loneliness scales to specify the risk profile, to delineate variations in the emotional tone and quality of loneliness, and to propose suitable interventions. The paper outlines a theoretical argument—drawing on moral philosophy—that prosociality and being needed are non-contingent, morally urgent human needs, postulating that the protective benefits of neededness vary according to at least four factors: the significance, persistence, non-instrumentality, and non-fungibility of the ways in which a person is needed. Finally, the paper considers implications for the design of appropriate remedies for loneliness.

description: We investigate the nonequilibrium dynamics of periodically driven Tomonaga-Luttinger liquids (TLLs) coupled to a thermal bath using a Floquet-Lindblad approach. When the coupling to the bath satisfies detailed balance, we obtain a condition for parametric instabilities to be suppressed, symmetrically for both chiralities. Remarkably, by designing a purely chiral coupling to the bath, instead of instability suppression, we uncover a driven-dissipative phase transition between the former symmetric parametric instability and a new chiral parametric instability. In the latter, a single chirality of bosonic quasiparticles gets exponentially amplified, leading to a dynamical chiral imbalance within the TLL, reminiscent of the non-Hermitian skin effect.

description: Objective: To examine the degree to which neighborhood socioeconomic deprivation influences youth assault injury risk. Study design: Population-based retrospective study of youth aged 10 to 24 years seeking emergency medical care between 2012 and 2019 at 14 hospitals in Vancouver, Canada. Neighborhood material and social deprivation were examined as independent predictors of assault injury, accounting for spatial autocorrelation and controlling for neighborhood drinking establishment density. Results: Our data included 4,166 assault injuries among 3,817 youth. Male sex, substance use and mental health disorders were common among victims of assault. Relative to the least deprived quintile of neighborhoods, assault injury risk was two-fold higher in the most materially deprived quintile of neighborhoods (incidence rate ratio [IRR] per quintile increase, 1.17; 95%CI, 1.06-1.30; p <0.05), and risk in the most socially deprived quintile was over three-fold greater than in the least deprived quintile (IRR per quintile increase, 1.35; 95%CI, 1.21,1.50; p <0.001). Assault risk was 147-fold higher between 2AM and 3AM on Saturday relative to the safest hours of the week. Conclusions: Neighborhood socioeconomic deprivation substantially increases the risk of youth assault injury. Youth violence prevention efforts should target socioeconomically deprived neighborhoods.

Publisher: name: Swinburne
Year: 2024

description: As per the Australian Bureau of Statistics, 2019 manufacturing contributed $100 billion to GDP annually. Manufacturing is multidisciplinary, comprised of convoluted and complex operations with inefficiencies, making Australia less competitive globally. The main related reasonings were reworks, rejigging, lack of controls, miscommunications, lack of decisions, customer individual product demands and inventory costs. The research developed a novel SM framework providing distinct benefits over traditional manufacturing validated with textile manufacturing. The SM framework used artificial intelligence to harness: i) efficiency gains of over 31%, and ii) enhanced decisions saving 18% of costs and iii) unique agility for low-volume personalised product manufacturing.
Criminalizing the School:  An Investigation of How Current School Safety and Disciplinary Policies Contribute to the Overrepresentation of Traditionally Marginalized Students within the Criminal Justice System
Creators: name: Clark, Dia
Publisher: name: Georgia State University
Year: 2019

description: This study focuses on the nature of school discipline policies and their impact on student sentiments about how they are viewed by school staff. The study follows the research to illustrate a connection between unremitting surveillance and discipline and corresponding higher levels of violence, drop-out rates, and student, as well as teacher, dissatisfaction. The study concludes that while violence must be met with consequences, too often the perception of potential student violence or criminal behaviors is influenced by racial bias. I contend that hostile school environments in which trust is lacking between school staff and students develops poor student self-perceptions and cause over-active disciplinary measures which can increase the presence of students from traditionally marginalized groups in the criminal justice system.

description: Zahlentheorie ist ein Gebiet der Mathematik, das sich mit der Lösung von algebraischen Gleichungen mit ganzzahligen Koeffizienten beschäftigt. Sie befasst sich mit einer großen Anzahl von Problemen, die meist scheinbar einfach und elementar sind, aber manchmal sehr schwierig zu lösen.
description: The Birch and Swinnerton-Dyer conjecture (BSD), proposed in the 1960s, is one of the fundamental open questions in pure Mathematics. It establishes a connection between the algebraic properties of the rational points of an elliptic curve and the analytic features of its associated L-function. This article provides an informal and relatively elementary introduction to the circle of ideas surrounding BSD. It does so by first introducing the much older problem of congruent numbers, which dates back to antiquity. This problem, which is to date still open, can be reformulated as a question about the rational points of a certain class of elliptic curves. The validity of BSD would lead to a positive answer to the congruent number problem. In turn, this problem is used in the text as a convenient testing ground for the state of our knowledge on BSD.
The article ends by recalling the fundamental role played by elliptic curves in the proof by Wiles and Taylor in the 1990’s of the famous Fermat’s Last Theorem. This proof relies on the deep and unexpected connection between elliptic curves and modular forms, which also implies the analytic continuation of the L-functions of elliptic
curves.

description: Buildings are geometric objects of a combinatorial nature. They are built from smaller elements called chambers and apartments. The article provides an introduction to this fascinating theory and explains the use of everyday language in mathematics. It starts out from the Heawood graph in Figure 1 and describes the algebraic model needed to analyze it. The author also comments on historical developments. Starting from Felix Klein’s Erlangen programme, the interaction and the unification of algebra and geometry have become a driving force in modern mathematics. The theory of buildings was initiated by Abel Prize laureate Jacques Tits. It is part of this fascinating story. A particularly important class of buildings was introduced by Jacques Tits and François Bruhat.
As an easy example, the article discusses the Bruhat-Tits tree shown in Figure 4. It also explains the connection with reflection groups via triangulated planes. At the end of the article the author briefly describes in which way buildings are relevant for his research. This concerns questions from number theory related to the Langlands programme.

description: Moduli spaces of Higgs bundles have appeared for different reasons in mathematical physics, topology and number theory. Recently, Marc de Cataldo, Tamas Hausel and Luca Migliorini observed a hitherto unexplained identity between invariants related to singularitiesof the integrable system defined by these spaces and arithmetic invariants of a closely related, non-singular space. They conjecture that this identity is a general phenomenon. In the article we survey the origins of this conjecture and show how they have connected very different areas of mathematics. In the process we indicate some of the unexpected applications that resulted from this passage between the different fields.

description: Mathematiker*innen beschäftigen sich gern mit Gleichungen, die zu kompliziert sind, als dass man sie mit herkömmlichen Methoden lösen könnte. Ein möglicher Zugang zu solchen Problemen besteht darin, nach Symmetrien zu suchen, die die Lösung vereinfachen.
description: Solutions of nonlinear differential equations tend to have singularities. At singular points, such solutions may not be smooth enough to solve the equation in a classical sense. Allowing singularities may be an important part of a mathematical model. The interplay between the differential equations of the model and the possible singularities is an important topic to understand when interpreting the solutions. For critically nonlinear differential equations, the study of singularities is also interesting with regard to symmetries. The symmetries of the solution may not be the same as those of the equation, and possible symmetries of singularities may be responsible for such a phenomenon. A discrepancy between symmetries can thus complicate the understanding of solutions to an equation. Meanwhile, symmetries can also be useful for finding solutions by reduction to a simpler problem. The article discusses such aspects of the theory and explains the phenomena in a rather simple geometric model. While it is used for illustration only, the models we are actually concerned with are taken from differential geometry and physics.

A Leaky Blood–Brain Barrier to Fibrinogen Contributes to Oxidative Damage in Alzheimer’s Disease
Creators: name: McLarnon, James G.
Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2022

description: The intactness of blood–brain barrier (BBB) is compromised in Alzheimer’s disease (AD). Importantly, evidence suggests that the perturbation and abnormalities appearing in BBB can manifest early in the progression of the disease. The disruption of BBB allows extravasation of the plasma protein, fibrinogen, to enter brain parenchyma, eliciting immune reactivity and response. The presence of amyloid-β (Aβ) peptide leads to the formation of abnormal aggregates of fibrin resistant to degradation. Furthermore, Aβ deposits act on the contact system of blood coagulation, altering levels of thrombin, fibrin clots and neuroinflammation. The neurovascular unit (NVU) comprises an ensemble of brain cells which interact with infiltrating fibrinogen. In particular, interaction of resident immune cell microglia with fibrinogen, fibrin and Aβ results in the production of reactive oxygen species (ROS), a neurotoxic effector in AD brain. Overall, fibrinogen infiltration through a leaky BBB in AD animal models and in human AD tissue is associated with manifold abnormalities including persistent fibrin aggregation and clots, microglial-mediated production of ROS and diminished viability of neurons and synaptic connectivity. An objective of this review is to better understand how processes associated with BBB leakiness to fibrinogen link vascular pathology with neuronal and synaptic damage in AD.

description: More often than not, laws are meant to regulate human behavior. However, human beings’ reactions to such regulations are to a large degree uncertain and one can only try to predict them. In that regard, the neighboring field of behavioral economics might provide relevant and necessary insights for effective regulation. However, the Court of Justice of the European Union might, should, or ought to rely on such findings when interpreting European Union (EU) secondary law, to give such rules the most effective meaning by limiting possible infringements on individuals’ fundamental rights. Built on an assessment of the Market in Financial Instruments Directive II (MiFID II), as part of European capital markets law, and with references to consumer protection law, the Taxonomy Regulation, and other European legal acts, this paper, first of all, demonstrates that not only the European legislator but also the Court can, in most situations, rely on behavioral economic findings. Although human behavior as well as results stemming from experimental research are to a certain degree uncertain, concepts developed in behavioral economics describe human behavior better than concepts implying (fully) rational behavior. In addition, obstacles – stemming from both the field of behavioral economics and legal methodology – that arise when applying these experimental findings to interpreting EU secondary law will be summarized and ideas to counter those obstacles are presented. The overall objective of this paper is to further a discussion on how to best incorporate findings from the field of behavioral economics into legal methodology. For this, the paper references, among others, European capital markets law but strives to abstract and generalize key aspects to facilitate a broader reception and discussion.

description: Der Fluss zur Totalvariation wird für viele Algorithmen aus der modernen Bildverarbeitung verwendet. Vor Kurzem ist nun die Herleitung eines Existenzresultates für das Hindernisproblem zu diesem Fluss gelungen, unter Verwendung von klassischen Konzepten aus der geometrischen Maßtheorie, die über 40 Jahre alt sind.
description: We describe a new result on the existence of solutions for an obstacle problem associated to the total variation flow. The total variation flow is famous for its applications in image reconstruction. The treatment of the obstacle problem, with possibly thin obstacles, requires utilization of concepts that were developed by the ingenious mathematician Ennio De Giorgi more than 40 years ago. We briefly describe these concepts and explain wow they can be applied to the above-mentioned obstacle problem for the total variation flow. In fact, the usual formulation of this problem might not have a solution if the prescribed obstacle contains “thin” parts of lower dimension. The strategy is to replace the original formulation of the obstacle problem with a relaxed version, using the concept of the De Giorgi measure. Together with his co-authors Prof. Dr. Verena Bögelein from Salzburg and Prof. Dr. Frank Duzaar from Erlangen, the author was able to derive an existence result for this relaxed problem by combining modern techniques for time-dependent partial differential equations with ideas from classical mathematical theory.

description: In subtropical plantations in southern China, how soil microbial communities respond to climate change-induced drought is poorly understood. A field experiment was conducted in a subtropical Eucalyptus plantation to determine the impacts of 50% of throughfall reduction (TR) on soil microbial community composition, function, and soil physicochemical properties. Results showed that TR reduced soil water content (SWC) and soil available phosphorus (AP) content. TR significantly altered 196 bacterial operational taxonomic units (OTUs), most of them belonging to Acidobacteria, Actinobacteria, and Proteobacteria, while there were fewer changes in fungal OTUs. At the phylum level, TR increased the relative abundance of Acidobacteria at 0–20 cm soil depth by 37.18%, but failed to influence the relative abundance of the fungal phylum. Notably, TR did not alter the alpha diversity of the bacterial and fungal communities. The redundancy analysis showed that the bacterial communities were significantly correlated with SWC, and fungal communities were significantly correlated with AP content. According to predictions of bacterial and fungal community functions using PICRUSt2 and FUNGuild platforms, TR had different effects on both bacterial and fungal communities. Overall, SWC and AP decreased during TR, resulting in greater changes in soil bacterial community structure, but did not dramatically change soil fungal community structure.

description: Modern variational methods in mathematical imaging formulate the task of denoising, deblurring, or reconstructing images – photographic or medical – as an optimization problem in which the goal is to find the “optimal” image that minimizes a weighted sum of a discrepancy term, which measures the distance of a candidate image to the given data, and a regularization term, which measures the abstract “goodness” of the candidate image. For the latter, the total variation has turned out to be especially suitable for images, since it allows jumps in the minimizer (corresponding to sharp edges in the image) while still imposing sufficient regularity otherwise to remove noise. However, this term is not differentiable, and hence efficient nonsmooth optimization methods are needed. For convex functions such as the total variation, techniques of convex analysis make it possible to characterize minimizers as fixed points that can be computed either through fixed-point iteration – leading to proximal point and splitting methods – or through iterative linearization – leading to semismooth Newton methods. Current research focuses on generalizing these approaches to nonconvex functions.

Das betrifft etwa den minimalen Energieverbrauch bei der Herstellung eines Produkts, die kürzeste Zeit, um von einem Punkt zu einem anderen zu gelangen oder die Gewinnmaximierung in einem Unternehmen. Bei vielen dieser Optimierungsaufgaben spielt Mathematik eine große Rolle.
description: Optimization is part of our daily lives. We aim to minimize the time it takes to reach a desired location or maximize a company’s profit. The number of optimization variables is quite high in many applications – it may range from several hundreds to billions. However, here we only discuss settings with two variables. Optimality conditions are used to compute critical points, some of which may be saddle points or have no meaning at all. This is not a problem – we can check additional conditions to reject these points. However, if we lose a minimizer, the optimal point is lost forever. Two simple examples illustrate the loss of solutions of two standard optimization methods (elimination and Lagrange). This knowledge is important for applications, as there are several classes of optimization problems (including Stackelberg games, optimization problems governed by variational inequalities) that generically possess such undesired properties.

description: This paper investigates the integration of generative AI tools within the User-Centered Design (UCD) framework, focusing on a case study involving design students from the University of Applied Sciences in Mainz. The study evaluates the benefits and limitations of AI tools in supporting the design process. The students developed an interactive solution using various AI tools throughout the UCD stages, including problem definition, ideation, prototyping, and user feedback. Findings indicate that while AI tools can aid in data analysis and idea generation, they often explore problems at a superficial level, making it challenging to achieve a deep understanding of the problem-solution interplay. Furthermore, the linear interaction mode of the AI tools used in this course and their limited collaborative capabilities were a major drawback.. The study highlights the importance of balancing AI use with human intuition and creativity to achieve more nuanced and effective design outcomes. Future research should focus on enhancing AI's collaborative features and context awareness to better integrate into the design process.

description: Entscheidungen begleiten uns im Alltag. Wenn Sie zum Beispiel eine Ware im Laden kaufen, entscheiden Sie sich für eine Marke. Wenn Sie das Haus verlassen, entscheiden Sie darüber, was Sie anziehen sollen. Oft treffen die Leute Entscheidungen anhand der unvollständigen oder unsicheren Information (zum Beispiel anhand der Information auf Etiketten oder der Wettervorhersage). Was ist eine optimale Entscheidung unter diesen Umständen? Wie soll man handeln um diese optimale Entscheidung zu treffen? All diese Fragen beantwortet die mathematische Entscheidungstheorie.
description: Decision problems are part of our everyday life. For example, if we want to buy a product in the store, we choose a brand. Before leaving the house, we decide what to wear. Often, people make decisions based on incomplete or uncertain information (for example etiquette or the weather forecast). What is an optimal decision under these circumstances? How should we act in order to make this optimal decision? These questions are answered using mathematical decision theory. An important class of decision problems are those that are time-dependent (dynamic) and irreversible. Such problems are quite natural, as every real decision must take into account the time-related changes the decision-maker has to adjust to. These types of decision problems can be extremely complex, involving changes in preferences, technologies, and resources. To solve a dynamic decision problem, we must make assumptions about how the decision-maker evaluates alternative strategies. The standard assumption is that the decision-maker maximizes the expected benefit. Furthermore, in order to calculate the best decision for today, the decision-maker must make the optimal decision for the future too, i.e. for any future scenarios. The search for the optimal decision should therefore not be made chronologically, but in reverse order, i.e. backwards in time, because the present optimum depends on the future optimum. This fundamental consideration forms the basis of the principle of dynamic programming developed by R. Bellman. The complexity of dynamic programming results primarily from the exponential growth in the number of possible scenarios with the increase in the number of possible values for the state variables, decision variables and/or the number of time periods. This exponential growth becomes a major challenge in dynamic programming applications. In this article I describe different strategies for dealing with this problem.

description: Our demo describes the development and interaction of our first prototype of GRACE, an embodied voice assistant. GRACE was designed to provide voice-based cognitive interventions to its users, and was first piloted with healthy adults in its current version. The body of GRACE, which was 3D printed, encases the internal components such as the Raspberry Pi, reSpeaker microphone, an AMOLED screen, and a bluetooth speaker. We utilized an open-source robotics platform and their simulation software for executing the script and commands for the voice interactions. A text-to-speech voice from ElevenLabs was used as the voice for GRACE. We were able to develop and design four activities, including two cognitive interactions based on cognitive stimulation therapy. The interaction consisted of an introductory warm-up activity, two cognitive interventions, and a concluding activity.
Bioactive ceramic coatings with antimicrobial properties to increase orthopaedic implant longevity
Creators: name: Pham, Duy Quang
Publisher: name: Swinburne

description: The short lifespan of orthopaedic implants is a major clinical problem, where failure occurs within a few months because of infection, or within 10 -15 years due to loosening. Most orthopaedic implants use titanium alloys (Ti-6Al-4V), which often cannot achieve sufficient integration with bone, and currently used hydroxyapatite coatings are prone to delamination and fragmentation. This thesis developed patented calcium silicate bioceramics for use as novel implant coatings that featured osteogenic and antimicrobial properties coupled with high bonding strength to prevent premature implant failure. This will reduce the costs associated with revision surgery and improve recipients' long-term quality of life.

description: Since Charles Darwin’s seminal book on the origin of species, biologists and mathematicians have been studying the complex interaction between natural selection, mutation and recombination. The article explains these driving forces in evolution and illustrates with examples motivated from evolutionary biology how mathematical theory is developed from applied problems. We first explain with adaptive dynamics an example of a model which uses averaging principles for forces acting on separated time scales. Adaptive dynamics models the accumulation of beneficial mutations and the emergence of new species. We then consider RNA viruses which evolve so fast that the epidemiological and evolutionary time scales become the same. We describe different shapes of family trees (so called phylogenies) and explain that a good notion for
capturing phylogenies is 0-hyperbolic metric spaces. We also discuss certain tree statistics that can be used to establish a notion of convergence of phylogenies. Finally, we explain with altruistic behaviour an example of cooperative selection and answer why altruistic behaviour may persist in natural populations.

description: In working and learning settings, collaborative work on shared documents, synchronously and asynchronously, is common and even necessary. Supporting tools are currently based on web applications such as GoogleDocs, Microsoft Word or Overleaf. These tools offer special functions to make collaborative editing of documents effective and efficient, but not for all user groups. There are already studies that examine such tools technically for their accessibility, but few studies examine the process of collaborative working on documents by people with and without disabilities, the real-world challenges and established practices. The question requires a socio-technical perspective to consider the impact on all stakeholders and to create sustainable solutions for accessible collaboration. The aim of this workshop is to shed light on this perspective from various angles, to discuss it and to provide new impetus for future developments in this area.
