• Beyond Trial and Error: Strategic Assessment of Decentralized Identity in US Healthcare. Göppinger, Sophia Maite Magdalena; Meier, Alexander; Elshan, Edona; Malekan, Omid; Leimeister, Jan Marco (2024).

  The US healthcare system relies on trustworthy and effective data exchange. Yet its data flows are impaired by pervasive conflicting interests and incentives and the lack of authentic data, leading to persistent inefficiencies. By ensuring authentic data, decentralized identity (ID) presents a potential solution. However, information systems (ISs) have historically shown high rates of unsuccessful deployment in healthcare. Since formative use case evaluation frameworks can enhance deployment success rates, this paper conducted a participatory action research study to develop and test an evidence-based, theory-informed, and practical framework for assessing healthcare use cases' amenability to decentralized ID. The framework serves healthcare organizations as a decision-support tool in choosing suitable use cases for decentralized ID and planning corresponding initiatives. For researchers, the socio-technical factors that determine use cases's amenability to decentralized ID enhance their understanding of this novel IS and the socio-technical change it brings about.

  Technological advances in generative artificial intelligence (GAI) have increased the relevance of pedagogical conversational agents (PCAs) like chatbots to support students. Despite their potential for learning as a service, PCAs are rarely used by educational institutions. They often neglect the benefits of group learning, like collaborative problem- solving, and insufficiently address learners’ motivational challenges in digital environments. To tackle these issues, we designed and evaluated a gamified PCA for information systems (IS) education with collaborative and competitive group learning capabilities. We investigated the effects of collaborative and competitive elements in PCA design using a 2x2 experiment (n = 120). Our findings show that collaborative game elements foster learners’ motivation and highlight the PCA’s role as a group learning moderator. This study contributes new knowledge on GAI in IS education, meaningful gamification in the PCA context, and computer-supported collaborative learning.

  Wenn es um Politik geht, dann gibt es eine grundlegende Regel: Diskussionen sollen möglichst sachlich und rational geführt werden und jegliche Emotionalität ist fehl am Platz. Die Neurowissenschaftlerin und Bestsellerautorin Maren Urner zeigt in ihrem neuen Buch, warum diese Abwertung von Gefühlen ein grundlegender Fehler ist und wir die Trennung von Emotionen und Verstand überwinden müssen, um als Gesellschaft zukunftsfähig zu sein. Auf wissenschaftlich gesicherter Basis macht Urner deutlich, dass wir als Menschen nur in der Anerkennung unserer radikalen Emotionalität als Individuen gut leben und als Spezies überleben können. So zeigt sie nicht zuletzt einen Weg auf, wie Gefühle politische Debatten und gesellschaftliche Diskurse bereichern können.
• Viktor Agartz oder: Ein Leben für und wider die Wirtschaftsdemokratie Jünke, Christoph in Biographische Miniaturen (2024). (1. Auflage ) Dietz, Berlin.

  Für Wolfgang Abendroth war er der beste ökonomische Kopf, über den die westdeutschen Arbeiterinnen und Arbeiter in der Nachkriegszeit verfügten, andere sahen in ihm den Leo Trotzki der westdeutschen Gewerkschaftsbewegung oder verglichen ihn mit Rosa Luxemburg. Vor allem jedoch war Viktor Agartz (1897–1964) einer der Gründerväter der Bundesrepublik und als gewerkschaftlicher und sozialdemokratischer Vordenker der 1940er- und 1950er-Jahre der wichtigste Programmatiker einer damals breit propagierten »neuen Wirtschaftsdemokratie«. 1955 wurde er gestürzt und aus der sozialdemokratischen Gewerkschaftsbewegung verdrängt. Als heimatlos gewordener Linkssozialist mischte sich Agartz weiterhin ein und formulierte unter anderem eine der wohl schärfsten Selbstkritiken wirtschaftsdemokratischer Mitbestimmungsideen. Gerade aus dieser konzeptionellen Spannung heraus lässt sich auch für heutige Debatten über Fragen der Demokratisierung der Wirtschaft noch einiges lernen.

• Pullout test in steel fiber reinforced concrete. Sérgio, Felipe (2024).

  Use of steel fibers in cement-based composites has become popular due to possibility of using that material as total or partial replacement of conventional reinforcement, as in floor slabs or tunnel cover. This reinforcement aims to improve composites properties with regard, mainly, to cracks propagation. It’s known that concrete has high compressive strength and durability, but its toughness is low, being considered a fragile material. The performance of the fiber as stress bridge depends on several factors, among them bond strength between fiber and matrix. Interfacial Transition Zone (ITZ) is one in which first cracks that lead to material failure appear. Some researches with mineral additives, such as rice husk ash (RHA), are aimed at ITZ densification. RHA has a high content of amorphous silica, which gives it high potential for its pozzolanic activity. That RHA characteristic is able to potentiate new hydration products formation, especially C-S-H, giving a higher density to cement matrix and pores and voids reduction. Research’s objective was to evaluate the effect of cement substitution by RHA, aiming to densify cement matrix to point where the adhesion stress with steel fiber was higher than in conventional mixture. For this, control specimens were produced and 15% of the cement replaced by RHA. Through the single fiber pullout test it was possible to measure the adhesion stress between steel fiber and cement matrix. Results indicate an increase in the adhesion strength with a long curing time, which confirms that the RHA hydration occurs late in relation to cement.
• Intelligent Efficient Routing and Localization in the Underwater Wireless Sensor Network to Improve Network Lifetime S, Vinayprasad M; N, Jayaram M (N. Meghanathan, ed.) (2024). (Vol. 16)

  The inefficiency of the localization process mostly causes delays and operational difficulties in wireless sensor network (WSN) topologies. When localization is suboptimal, the time required for path creation significantly increases, leading to reduced network lifetime and diminished routing efficiency. To address these critical issues, our research focuses on developing a novel procedure that optimizes routing and localization. In this context, localization is the initial step for reaching sensor terminals, followed by activating the routing mechanism. To tackle these issues in Underwater Wireless Sensor Networks (UWSN), the proposed work presents the Elman Bat-based Hello Routing (EBbHR). The primary objective of our research is to locate wireless sensor nodes within the designed UWSN effectively. The process is initiated to achieve this by creating the necessary wireless sensor hubs within the MATLAB Simulink environment. Subsequently, the novel EBbHR function is activated to facilitate the precise localization of all sensor hubs, thereby enhancing the overall data transmission. The success of the designed EBbHR is assessed by considering UWSN factors, and a comparison with current approaches is carried out to show the advancements made by the model.

• Injury-dependent wound care behavior in the desert ant <i>Cataglyphis nodus</i>. Beydizada, Narmin I.; Abels, Antonia; Schultheiss, Patrick; Frank, Erik T. (2024). 78(97)

  Ants often face injuries during foraging, or interspecific competition, elevating infection risk and mortality among the wounded. To avoid this, ants engage in wound care on injured nestmates as a form of social immunity. In this study, we show that Cataglyphis nodus desert ants perform differentiated wound care behavior, depending on wound location and state. Leg-injured ants received significantly more wound care than antenna-injured ants. However, leg wounds with induced infections received barely any wound care from nestmates, leading to similar levels of mortality in isolation and inside the nest. Instead, such leg-infected ants were mainly found outside of the nest. Infections of antennal wounds showed no change in the level of wound care, nor increased mortality. Our results suggest that the level of wound care in ants can be flexibly adjusted to the perceived mortality risk of injuries. Leg injuries pose a greater risk of infection and mortality compared to antennal injuries, likely because of the larger wound area and increased vascular circulation, necessitating intensive prophylactic care to prevent infection. This study is the first to show wound care in Cataglyphis ants, despite their short lifespan, and offers significant insights into social immunity mechanisms.

• Active Learning Entropy Sampling based Clustering Optimization Method for Electricity Data Qingnan, Wang; Zhaogong, Zhang (2022). (Vol. 14) Pellegrini Editore.

  Clustering is a crucial part in the field of data mining, and common clustering methods include divisionbased methods, hierarchy-based methods, density-based methods, and grid-based methods. In order to improve the accuracy of clustering, an optimization study is made mainly for the division-based method FCM clustering, and an FCM clustering method that integrates active learning and principal component analysis (PCA) is proposed. The method first uses principal component analysis to reduce the dimensionality of the data to reduce the computation of electricity data, then trains the sample model by active learning, and introduces the entropy (Entropy) method in the uncertainty sampling method, the larger the entropy means the greater the uncertainty of the sample, and the smaller the entropy means the smaller the uncertainty of the sample, so as to filter the electricity data, and finally the electricity data are clustered by FCM clustering The power data is finally categorized by FCM clustering, and with the proliferation of power data, the power data can be more accurately categorized using this method to achieve the stability of the power grid as well as the utilization rate. Experimental results on three datasets show that this method improves the accuracy of power data clustering by up to 2 percentage points compared to the traditional clustering method without active learning, and achieves good results in each dataset compared to other methods.

  The Bayesian approach to data analysis provides a powerful way to handle uncertainty in all observations, model parameters, and model structure using probability theory. Probabilistic programming languages make it easier to specify and fit Bayesian models, but this still leaves us with many options regarding constructing, evaluating, and using these models, along with many remaining challenges in computation. Using Bayesian inference to solve real-world problems requires not only statistical skills, subject matter knowledge, and programming, but also awareness of the decisions made in the process of data analysis. All of these aspects can be understood as part of a tangled workflow of applied Bayesian statistics. Beyond inference, the workflow also includes iterative model building, model checking, validation and troubleshooting of computational problems, model understanding, and model comparison. We review all these aspects of workflow in the context of several examples, keeping in mind that in practice we will be fitting many models for any given problem, even if only a subset of them will ultimately be relevant for our conclusions.

• Estimates of introgression as a function of pairwise distances. Pfeifer, Bastian; Kapan, Durrell D. (2019). 20(1) 207.

  Research over the last 10 years highlights the increasing importance of hybridization between species as a major force structuring the evolution of genomes and potentially providing raw material for adaptation by natural and/or sexual selection. Fueled by research in a few model systems where phenotypic hybrids are easily identified, research into hybridization and introgression (the flow of genes between species) has exploded with the advent of whole-genome sequencing and emerging methods to detect the signature of hybridization at the whole-genome or chromosome level. Amongst these are a general class of methods that utilize patterns of single-nucleotide polymorphisms (SNPs) across a tree as markers of hybridization. These methods have been applied to a variety of genomic systems ranging from butterflies to Neanderthals to detect introgression, however, when employed at a fine genomic scale these methods do not perform well to quantify introgression in small sample windows.
