To tackle this challenge, on the one hand, modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight design offers various possibilities. Multi-Material Design (MMD) involves designing car\r\nbodies that combine different materials that require joining. Given the variety of materials, mechanical joining\r\nprocesses are preferred. Especially the current development of the Giga/Mega-casting process concerning\r\naluminium casting and the subsequent mechanical joining illustrates the challenges of this material group. In car\r\nproduction, aluminium castings are mainly made from aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient ductility leads to crack initiation during mechanical joining. Cast parts are therefore often\r\nused in areas of the car body that are exposed to high-pressure loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure through tailored solidification rates and a developed heat-treatment chain strategy adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical, and joining properties are used to develop a\r\nsolidification-joining correlation for the SPR process across a range of Si contents and solidification rates. The\r\npurpose is to develop the ability to produce suitable aluminium castings with sufficient joinability, thereby\r\nimproving versatility." article_type: original author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Pia Katharina full_name: Kaimann, Pia Katharina id: '44935' last_name: Kaimann - first_name: Ina full_name: Stratmann, Ina last_name: Stratmann - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Johann Moritz Benedikt full_name: Klöckner, Johann Moritz Benedikt last_name: Klöckner - first_name: Moritz full_name: Mann, Moritz last_name: Mann - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Neuser M, Kaimann PK, Stratmann I, et al.

Self-pierce riveting has become a prevalent technique for sheet metal assembly, especially in automotive applications. Achieving proper joint geometry and adequate load-bearing capacity depends on appropriate tool selection and precise process control. Material properties and condition also play a significant role in process performance. To accommodate the inevitable variations in component characteristics during production, a robust and stable joining process is essential. The study focuses on investigating the influence of preformed joining partners on the joining process and the joint's load capacity. An EN AW-6014 in T4 condition, as well as an HCT590X, are used as materials for this study. For this purpose, an exemplary process chain consisting of the steps of performing, joining, and shear load testing is studied. Each process step is implemented using an FE model to predict the outcome of subsequent steps. For analysis of the influence of pre-strain, an optimisation software is used to plan and execute variations of the process. These variations are used to create a meta-model that can describe the relationships between pre-forming and characteristic parameters of subsequent process steps. The resulting model is validated by comparing simulation and experimental data. Finally, in a novel approach, the robustness of the presented process chain is analyzed in terms of a tolerable performance level for the joining partners. article_number: '100391' author: - first_name: Jean-Patrick full_name: Ludwig, Jean-Patrick id: '76631' last_name: Ludwig - first_name: Emil full_name: Tolke, Emil last_name: Tolke - first_name: Malte Christian full_name: Schlichter, Malte Christian id: '61977' last_name: Schlichter - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 citation: ama: Ludwig J-P, Tolke E, Schlichter MC, Bobbert M, Meschut G.

Ziel des vorliegenden Beitrags ist es, empirisch zu untersuchen, welche Bedeutung festen Zeitfenstern für die Lehrkräftekooperation im Klassenteam, im Jahrgangsteam und im Fachteam für die Arbeitszufriedenheit zukommt. Weiterhin soll überprüft werden, ob Teile der Zusammenhänge über die Zufriedenheit mit der Kooperationshäufigkeit und die kollektive Selbstwirksamkeitsüberzeugung der Lehrkräfte erklärt werden können. Dazu werden Daten aus dem BMBF-geförderten Projekt BiFoKi mit N=194 Lehrkräften und N=28 Schulleitungen analy­siert.

In inclusive schools, regular school teachers and special needs teachers must co­operate in order to ensure that all pupils receive the best possible support. To do this, however, they need time slots that many teachers say are not sufficient. The aim of this article is to em­pirically investigate the importance of fixed time slots for teacher cooperation in the class team, the year team and the expert team for job satisfaction. Furthermore, it will be examined whether parts of the correlations can be explained by satisfaction with the frequency of cooperation and the teachers' collective self-efficacy expectations. To this end, data from the BMBF-funded BiFoKi project with N=194 teachers and N=28 head teachers will be analyzed. The results show that fixed time slots for cooperation in the different teams are associated with increased job satisfaction and are mediated in part by collective self-efficacy expectations. alternative_title: - Time for job satisfaction?

Multi-material design and the increasing trend towards producing large structural components using the megacasting process pose considerable challenges, particularly in the mechanical joining of aluminium-silicon (AlSi) castings. These castings typically exhibit low ductility and are prone to cracking when mechanically joined. Based on the excellent castability of hypoeutectic AlSi alloys, these are applied in sand casting and die casting as well as in megacasting. With a silicon content between 7 wt% and 12 wt%, these AlSi-alloys have a plate-like silicon phase that initiates cracks during mechanical joining. To enhance the joinability of castings, the research hypothesis is that improved solidification conditions enable a significant modification in the microstructure and therefore, increase the mechanical properties. During the manufacture of the castings using the sand casting process, the solidification conditions within the structural elements are varied to modify the microstructure to obtain castings with graded microstructure. The castings are evaluated using mechanical, microstructural and joining testing methods and finally, a microstructure-joinability correlation is established. article_number: '01081' article_type: original author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Malte Christian full_name: Schlichter, Malte Christian id: '61977' last_name: Schlichter - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: Neuser M, Schlichter MC, Hoyer K-P, Bobbert M, Meschut G, Schaper M.

The scale spanning heterogeneity of their material structure and its influence on the material behavior, however, presents significant challenges for most joining technologies, such as self-piercing riveting (SPR). During mechanical joining, the material structure is significantly altered within and around the joining zone, heavily influencing the material behavior. A comprehensive understanding of the underlying phenomena of material alteration during the SPR process is essential as basis for validating numerical simulations. This study examines the material structure at ten stages of a step-setting test of SPR with two FRTP sheets with glass-fiber reinforcement. Utilizing X-ray computed tomography (CT), the damage phenomena within different areas of the setting test are analyzed three-dimensionally and key parameters are quantified. Dominating phenomena during the penetration of the rivet into the laminate are fiber failure (FF), interfiber failure (IFF) and fiber bending, while delamination, fiber kinking and roving splitting are also observed. At the final stages, the bottom layers of the second sheet collapse and form a bulge into the cavity of the die. author: - first_name: Alrik full_name: Dargel, Alrik id: '114764' last_name: Dargel - first_name: Benjamin full_name: Gröger, Benjamin last_name: Gröger - first_name: Malte Christian full_name: Schlichter, Malte Christian id: '61977' last_name: Schlichter - first_name: Johannes full_name: Gerritzen, Johannes id: '105344' last_name: Gerritzen orcid: 0000-0002-0169-8602 - first_name: Daniel full_name: Köhler, Daniel id: '83408' last_name: Köhler - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Maik full_name: Gude, Maik last_name: Gude - first_name: Robert full_name: Kupfer, Robert last_name: Kupfer citation: ama: 'Dargel A, Gröger B, Schlichter MC, et al.

In particular, the car body offers several opportunities for weight reduction. Multi-material designs are increasingly being applied to select the most suitable material for the respective load and ultimately achieve synergy effects. For example, aluminium castings are used at the nodes of a spaceframe body. Subsequently, these are joined with profiles to form the bodyshell. To join different materials mechanical joining techniques, such as semi-tubular self-piercing riveting, are deployed. According to the current state of the art, cracks occur in the aluminium castings during the mechanical joining process as a result of the high degree of deformation. Although the aluminium casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent castability. In particular, the ability to cast thin structural parts is enabled by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis study addresses the mechanical joining properties of the near eutectic aluminium casting alloy AlSi12, depending on different microstructures. These are achieved by annealing processes and modifying agents. Through an adapted heat treatment, the previously lamellar morphology can be transformed into a globular morphology, which leads to increased ductility and prevents the formation of cracks during the self-piercing riveting (SPR). The joinability is investigated using different die geometries, whereas the joint formation is analysed regarding crack initiation. To evaluate the increased ductility, microstructural and mechanical tests are performed and finally, a microstructure-joinability correlation is established." article_type: original author: - first_name: Moritz full_name: Neuser, Moritz id: '32340' last_name: Neuser - first_name: Pia Katharina full_name: Holtkamp, Pia Katharina id: '44935' last_name: Holtkamp - first_name: Kay-Peter full_name: Hoyer, Kay-Peter id: '48411' last_name: Hoyer - first_name: Fabian full_name: Kappe, Fabian id: '66459' last_name: Kappe - first_name: Safak full_name: Yildiz, Safak last_name: Yildiz - first_name: Mathias full_name: Bobbert, Mathias id: '7850' last_name: Bobbert - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Mirko full_name: Schaper, Mirko id: '43720' last_name: Schaper citation: ama: 'Neuser M, Holtkamp PK, Hoyer K-P, et al.

These can include operating vehicles that differ regarding their characteristics and application profile from privately owned cars in motorized individual transport. Studies on life cycle assessment and life cycle engineering of vehicle lightweight structures are mainly limited to these privately owned cars and the impact category of climate change. In this paper, a method for life cycle assessment-based engineering of lightweight structures in vehicles for various mobility system applications, including on-demand mobility services, is developed. The method enables the holistic life cycle assessment of lightweight structures in different mobility system applications considering parameter changes at the upstream products, component, subsystem, vehicle and mobility system levels, as well as the integration of results into engineering activities. A case study is used to show that the vehicle and mobility system application of lightweight structures can significantly influence their environmental impacts and the selection of ecologically preferable product designs. The application in vehicles for on-demand mobility services can lead to an increase in absolute use stage energy demand and environmental impacts compared to applications in privately owned vehicles for motorized individual transport. However, normalized to the transport performance provided, the lifecycle environmental impacts of structural components in vehicles for on-demand mobility services can be lower than in vehicles for motorized individual transport. The paper contributes methodically and with quantitative results to improved decision making in life cycle engineering activities for lightweight structures in mobility system applications. article_number: '101058' article_type: original author: - first_name: Moritz full_name: Ostermann, Moritz id: '44763' last_name: Ostermann orcid: https://orcid.org/0000-0003-1146-0443 - first_name: Eric full_name: Dierkes, Eric last_name: Dierkes - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten orcid: 0009-0001-6433-7839 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Ostermann M, Dierkes E, Marten T, Tröster T.

Companies try to tackle challenges regarding their differentiation and profitability using digital services. One specific type of digital services are smart services, which are digital services built on data from smart products. Introducing these kinds of offerings into the portfolio of manufacturing companies is not trivial. Moreover, they require conscious action to align all relevant capabilities to realize the respective business goals. However, what capabilities are generally relevant for smart services remains opaque. We conducted a systematic literature review to identify them and extended the results through an interview study. Our analysis results in 78 capabilities clustered among 12 principles and six dimensions. These results provide significant support for the smart service transformation of manufacturing companies and for structuring the research field of smart services. author: - first_name: Christian full_name: Koldewey, Christian id: '43136' last_name: Koldewey orcid: https://orcid.org/0000-0001-7992-6399 - first_name: Timm full_name: Fichtler, Timm id: '66731' last_name: Fichtler orcid: https://orcid.org/0000-0001-6034-4399 - first_name: Michel full_name: Scholtysik, Michel id: '50562' last_name: Scholtysik - first_name: Jan full_name: Biehler, Jan last_name: Biehler - first_name: Nick full_name: Schreiner, Nick last_name: Schreiner - first_name: Franziska full_name: Sommer, Franziska last_name: Sommer - first_name: Maximilian full_name: Schacht, Maximilian last_name: Schacht - first_name: Jonas full_name: Kaufmann, Jonas last_name: Kaufmann - first_name: Martin full_name: Rabe, Martin last_name: Rabe - first_name: Joachim full_name: Sedlmeier, Joachim last_name: Sedlmeier - first_name: Roman full_name: Dumitrescu, Roman id: '16190' last_name: Dumitrescu citation: ama: 'Koldewey C, Fichtler T, Scholtysik M, et al.

Existing approaches often utilize impedance measurements over a range of frequencies or velocity measurements and require additional equipment or sensors, such as a laser Doppler vibrometer. Furthermore, the non-negligible effects of varying operating conditions are often unconsidered. To minimize the need for additional sensors while maintaining the dependability of piezoelectric bending actuators irrespective of varying operating conditions, an online diagnostics approach is proposed. To this end, time- and frequency-domain features are extracted from monitored current signals to reflect hairline crack development in bending actuators. For validation of applicability, the presented analysis method was evaluated on piezoelectric bending actuators subjected to accelerated lifetime tests at varying voltage amplitudes and under external damping conditions. In the presence of a crack and due to a diminished stiffness, the resonance frequency decreases and the root-mean-square amplitude of the current signal simultaneously abruptly drops during the lifetime tests. Furthermore, the piezoelectric crack surfaces clapping is reflected in higher harmonics of the current signal. Thus, time-domain features and harmonics of the current signals are sufficient to diagnose hairline cracks in the actuators. article_number: '521' article_type: original author: - first_name: Osarenren Kennedy full_name: Aimiyekagbon, Osarenren Kennedy id: '9557' last_name: Aimiyekagbon - first_name: Amelie full_name: Bender, Amelie id: '54290' last_name: Bender - first_name: Tobias full_name: Hemsel, Tobias id: '210' last_name: Hemsel - first_name: Walter full_name: Sextro, Walter id: '21220' last_name: Sextro citation: ama: Aimiyekagbon OK, Bender A, Hemsel T, Sextro W.

For example, property damage to shared accommodations imposes burdens on both sharing platforms and hosts, especially if misbehaving guests purposefully, not coincidentally conceal, or fail to report damages. Such misbehavior might be facilitated by remote listing management and the lack of face-to-face interactions between hosts and guests. Therefore, this study investigated the effects of host–guest interaction modes (face-to-face, online-only) and frequency on guests’ misbehavior concealment intentions. Social identification and irritation emerged as bright- and dark side mediators, respectively. Guests who interacted face-to-face (vs. online-only) with hosts exhibited weaker intentions to conceal their misbehavior due to increased social identification. Platforms can elicit social identification by engaging guests in virtual communities. However, when face-to-face interactions become excessive, guests experience irritation and are more likely to conceal their misbehavior. These insights offer practical implications for both peer-to-peer sharing platforms and hosts. article_number: '114582' article_type: original author: - first_name: Edna full_name: Ozuna, Edna id: '103813' last_name: Ozuna - first_name: Lena full_name: Steinhoff, Lena id: '4336' last_name: Steinhoff citation: ama: 'Ozuna E, Steinhoff L. “Look me in the eye, customer”: How do face-to-face interactions in peer-to-peer sharing economy services affect customers’ misbehavior concealment intentions?

These challenges can critically impact assets in the distribution grid—e.g., switchgears—intensifying the need to plan, conduct, and manage the maintenance of such assets. Predictive maintenance strategies that analyze assets' current and historical condition data have been discussed as promising approaches toward that end. However, the extant research focuses on designing and improving analytical algorithms or information technology (IT) artifacts while not considering how a maintenance service is cocreated by companies with IT. This research article posits that IT and service must be aligned closely, presenting an ensemble artifact comprising a digital industrial platform and a smart service system for predictive maintenance on the distribution grid. The artifact is evaluated by conducting a willingness-to-pay analysis with asset operators, documenting their demand for condition monitoring and predictive maintenance as an integrated solution, although they still struggle with even getting the condition data of their assets. Building on these results, we formalize the knowledge in the form of design principles and implications for managing the maintenance of critical assets in the distribution grid. article_type: original author: - first_name: Philipp full_name: zur Heiden, Philipp id: '64394' last_name: zur Heiden - first_name: Jennifer full_name: Priefer, Jennifer id: '82872' last_name: Priefer - first_name: Daniel full_name: Beverungen, Daniel id: '59677' last_name: Beverungen citation: ama: zur Heiden P, Priefer J, Beverungen D.

This creates new challenges for organizations trying to consistently deliver high-quality customer experiences. In this paper we conduct an empirical analysis of customers’ preferences and their willingness-to-pay for different degrees of process transparency, using the example of digitally-enabled business-to-customer delivery services. Applying conjoint analysis, we quantify customers’ preferences and willingness-to-pay for different service attributes and levels. Our contributions are two-fold: For research, we provide empirical measurements of customers’ preferences and their willingness-to-pay for process transparency, suggesting that more is not always better. Additionally, we provide a blueprint of how conjoint analysis can be applied to study design decisions regarding changing an organization’s digital line of visibility. For practice, our findings enable service managers to make decisions about process transparency and establishing different levels of service quality.\r\n" author: - first_name: Katharina full_name: Brennig, Katharina id: '51905' last_name: Brennig - first_name: Oliver full_name: Müller, Oliver id: '72849' last_name: Müller citation: ama: 'Brennig K, Müller O.

Agency is understood as a multifaceted construct describing the idea that human beings make choices, act on these choices, and thereby exercise influence on their own lives as well as their environment. We argue that the concept is discussed from three different perspectives in the literature—transformational, dispositional, and relational—that are each related to learning and development in work contexts. These perspectives do not reflect incompatible positions but rather different aspects of the same phenomena. The chapter also offers an avenue of insight into empirical studies that employ agency as a central concept as well as discussions about concepts that closely overlap with ideas of human beings as agents of power and influence. author: - first_name: Michael full_name: Goller, Michael id: '30984' last_name: Goller orcid: 0000-0002-2820-9178 - first_name: Susanna full_name: Paloniemi, Susanna last_name: Paloniemi citation: ama: 'Goller M, Paloniemi S.

This discovery can be achieved with continuous experimentation, testing different software variants with distinct user groups, and deploying the superior variant for all users. However, existing approaches do not focus on explicit modeling of variants and experiments, which offers advantages such as traceability of decisions and combinability of experiments. Therefore, our vision is the provision of model-driven continuous experimentation, which provides the developer with a framework for structuring the experimentation process. For that, we introduce the overall concept, apply it to the experimentation on component-based software architectures and point out future research questions. In particular, we show the applicability by combining feature models for modeling the software variants, users, and experiments (i.e., model-driven) with MAPE-K for the adaptation (i.e., continuous experimentation) and implementing the concept based on the component-based Angular framework. author: - first_name: Sebastian full_name: Gottschalk, Sebastian id: '47208' last_name: Gottschalk - first_name: Enes full_name: Yigitbas, Enes id: '8447' last_name: Yigitbas orcid: 0000-0002-5967-833X - first_name: Gregor full_name: Engels, Gregor id: '107' last_name: Engels citation: ama: 'Gottschalk S, Yigitbas E, Engels G.

The educational knowledge, competence self-assessments and their development as well as the assessment of the goals achieved by students in the internship are considered, taking into account the orientation of the teacher education course towards a school type. In order to contextualize the results of the measurement of educational knowledge and those of the survey of competence self-assessments (N = 304), ideas are shown how the relationship between knowledge and ability is constituted and findings on the type of school-specific professionalization are summarized. Subsequently, hypotheses are derived, the design of the study, the method and the test instruments are described, the results are presented and discussed. Contrary to expectations, the results show that neither the educational science knowledge, the competence self-assessments and their development nor the assessment of the goals achieved in the internship by pros- pective teachers differ depending on the type of school. The discussion relates to on the structure of the teacher training courses, the mental figures for the development of skills and the conception of the measuring instruments.\r\n" alternative_title: - Ergebnisse der Messung pädagogischer Kompetenzen Studierender in Deutschland author: - first_name: Carina full_name: Caruso, Carina id: '23123' last_name: Caruso - first_name: Andreas full_name: Seifert, Andreas last_name: Seifert citation: ama: Caruso C, Seifert A.

Dabei werden sowohl das bildungswissenschaftliche Wissen als auch die Entwicklung der Kompe­tenzselbsteinschätzungen in den Bereichen Unterrichten, Erziehen, Beurteilen und Innovieren unter Berücksichtigung individueller Voraussetzungen (Alter, Geschlecht, Abiturnote, Bachelornote, Konfession) betrachtet. Um die Ergeb­nisse hinsichtlich ihrer Bedeutung für die Professionalisierung angehender Lehrkräfte diskutieren zu können, wird, den empirischen Erkenntnissen voranstehend, die Bedeutung von Wissen für berufliches Können herausgearbeitet. Daran anschließend werden Hypothesen hergeleitet, die Anlage der Studie sowie die Testinstrumente vorgestellt, die Ergebnisse präsentiert und diskutiert. Die Ergebnisse zeigen, dass die Abitur- und Bachelornote die Varianz hinsichtlich des pädagogischen Wissens aufklären, sich eine signifikante Entwicklung der Kompetenzselbsteinschätzungen angehender Lehrkräfte feststellen lässt, aber sich angehende Religionslehrkräfte kaum von anderen Studierenden unterscheiden. Die Diskussion nimmt u. a. Rückbezug auf die Denkfiguren zur Entwicklung berufli­chen Könnens und benennt Limitationen, die mit der Studie und Kompetenzmessungen verbunden sind.

Der Beitrag zielt insbesondere darauf, repräsentative Ergebnisse der Kompetenzmessung zu präsentieren und dabei potenzielle Einflussfaktoren auf die studentische Kompetenzent­wicklung zu beleuchten.

In doing so, both the knowledge of the educational sciences and the development of competence self-assessments in the fields of teaching, education, assessment andinnovating are taken into account. The study makes use of the following individual requirements: age, sex, Abitur grade, Bachelor grade, Confession. In order to be able to discuss the re-sults regarding their importance for the professionalization of prospective teachers, the importance of knowledge for professional skills is highlighted, preceded by empirical findings. Subsequently, hypotheses are derived, the plan of the study as well as the test instruments are presented, the results presented and discussed. The results show that the Abitur and Bachelor grades clarify the variance in pedagogical knowledge, that there is a significant development in the competence self-assessments of prospective teachers, and that prospective religious teachers are not different from other students. The discussion takes into account, among other things, the ideas for the devel-opment of professional skills and identifies limitations associated with the study. This is followed by the formula-tion of an outlook. The main aim of the paper is to present representative results of the competence measurement and to examine potential influencing factors on student competence development. A conglomerate of resilient knowledge enriched by this aims to be used in the long term to derive teacher training didactic considerations that support student professionalization.' author: - first_name: Carina full_name: Caruso, Carina id: '23123' last_name: Caruso - first_name: Andreas full_name: Seifert, Andreas last_name: Seifert citation: ama: Caruso C, Seifert A.
