QUANTUM COMBINATORIAL DESIGN
Authors: Gopsill James , Johns Guy , Hicks Ben
Published: August 2021

Combinatorial Design such as configuration design, design optioneering, component selection, and generative design, is common across engineering. Generating solutions for a combinatorial design task often involves the application of classical computing solvers that can either map or navigate design spaces. However, it has been observed that classical computing resource power-law scales with many design space models. This observation suggests classical computing may not be capable of modelling our future design space needs.

To meet future design space modelling needs, this paper examines quantum computing and the characteristics that enables its resources to scale polynomially with design space size. The paper then continues to present a combinatorial design problem that is subsequently represented, constrained and solved by quantum computing. The results of which are the derivation of an initial set of circuits that represent design space constraints. The study shows the game-changing possibilities of quantum computing as an engineering design tool and is the start of an exciting new journey for design research.
REPRESENTATION AND APPLICATION OF DIGITAL STANDARDS USING KNOWLEDGE GRAPHS
Authors: Luttmer Janosch , Ehring Dominik , Pluhnau Robin , Nagarajah Arun
Published: August 2021

Standards are an important source of knowledge in product development. Due to the increasing digitization of the product development process, standard development organizations aim to develop machine-actionable standards that automatically enforce operations in output devices. However, the current representation format in PDF or XML does not meet the requirements of machine-actionable standards. This paper examines existing approaches towards the representation of XML data in knowledge graphs and their transferability towards the domain of digital standards. Based on these approaches, the paper aims to develop and validate a concept for transferring standard content from XML format to a graph-based representation, using the example of formulas. For this purpose, a concept for the automatic identification, extraction and modeling of formulas will be presented. Afterwards, the concept is validated using the example of DIN ISO 281 whereas a chatbot application serves as conversational user interface. It is proven, that knowledge graphs are suitable for the representation of machine-actionable standard content. Future work will investigate the abstraction towards a general approach as well as further information objects of standards.
SEEING FROM THE USERS' EYES: AN OUTLOOK TO VIRTUAL-REALITY BASED EMPATHIC DESIGN RESEARCH
Authors: Hu Xinhui , Nanjappan Vijayakumar , Georgiev Georgi V.
Published: August 2021

The extent to which designers can understand users often determines the quality of design outcomes. A deep understanding of users allows the designers to focus on the right problem and make optimal design decisions, which encouraged designers to empathize with users. However, the current imagination-based empathizing strategy appears to be too susceptible to their previous experience and knowledge, which has been questioned concerning effectiveness and accuracy. On the other hand, Virtual Reality (VR) technology provides an opportunity for designers to gain experience-driven empathy by immersing them in a virtual environment that mimics the users' surroundings as if they are seeing the world from users' eyes. While abundant studies covered empathy VR and empathy for design, limited attention has been paid to the chance of bringing VR, empathy, and design research together. Addressing this gap, this study explored literature across domains, identified major concerns about this approach, synthesized the evidence, and discussed the feasibility and validity of the VR-based empathic design research approach.
APPROACH FOR THE DEVELOPMENT AND APPLICATION OF TARGET PROCESS MODULE SETS
Authors: Albers Albert , Wilmsen Miriam , Gericke Kilian
Published: August 2021

The implementation of agile frameworks, such as SAFe, in large companies causes conflicts between the overall product development process with a rigid linkage to the calendar cycles and the continuous agile project planning. To resolve these conflicts, adaptive processes can be used to support the creation of realistic target-processes, i.e. project plans, while stabilizing process quality and simplifying process management. This enables the usage of standardisation methods and module sets for design processes.

The objective of this contribution is to support project managers to create realistic target-processes through the usage of target-process module sets. These target-process module sets also aim to stabilize process quality and to simplify process management. This contribution provides an approach for the development and application of target-process module sets, in accordance to previously gathered requirements and evaluates the approach within a case study with project managers at AUDI AG (N=21) and an interview study with process authors (N=4) from three different companies.
STRATEGIC DESIGN OPPORTUNITIES TO INCREASE SUSTAINABLE FASHION AWARENESS AND BEHAVIOUR
Authors: Das Marie , Herweyers Laure , Moons Ingrid , Du Bois Els
Published: August 2021

Fast fashion, with its focus on cheap clothing and everchanging trends, has an enormous negative environmental and social impact. Despite rising consumer awareness and slow fashion as an emerging trend, many consumers often still rely on fast fashion. This research aims to create insights into why customers keep returning to fast fashion and what is holding them back from buying sustainable fashion. This is done through a quantitative survey (n=521) and qualitative semi-structured interviews (n=9). Based on the findings, opportunities are defined for designers on how, where, and when to intervene, and on which target group to focus. The main obstacles that counter slow fashion are (i) a lack of understandable and clear information, (ii) the price or available budget, and (iii) the importance of social influence. Strategic design interventions should focus on educating eco-conscious and social-conscious customers based on their personal definition of sustainable fashion. By providing in-store information during time of purchase, designers can create new shopping experiences, educate customers using a positive note and build customer relations with the retailer. Further research should extend these insights with retailers' perspectives.
STUDENT PARTICIPANTS IN EMPIRICAL STUDIES IN ENGINEERING DESIGN - A COLLECTION OF REFLECTIONS TO IMPROVE YOUR STUDY QUALITY
Authors: Üreten Selin , Sankowski Olga , Krause Dieter
Published: August 2021

Engineering design has a broad variety of approaches, methods and methodologies to conduct, evaluate and validate research. This contribution focuses on empirical studies and divides existing approaches and classifies them according to a scheme with criteria and boundary conditions, such as participants (students, researchers), the length of the study, the incorporation of the study into the curriculum etc. There are certain ideas, challenges and recommended practices associated with each environment and scenario. Knowing them will help design method developers in engineering design who want to conduct empirical studies but have little or no experience with student participants. Therefore, conducted studies from the research institute are mapped onto the classification scheme and synthesized challenges and recommended practices associated with laboratory conditions and student participants will be presented.
AUTOMATED FUNCTIONAL ANALYSIS OF PATENTS FOR PRODUCING DESIGN INSIGHT
Authors: Jiang Pingfei , Atherton Mark , Sorce Salvatore
Published: August 2021

Patent analysis is a popular topic of research. However, designers do not engage with patents in the early design stage, as patents are time-consuming to read and understand due to their intricate structure and the legal terminologies used. Manually produced graphical representations of patent working principles for improving designers’ awareness of prior art have been demonstrated in previous research. In this paper, an automated approach is presented, utilising Natural Language Processing (NLP) techniques to identify the invention working principle from the patent independent claims and produce a visualisation. The outcomes of this automated approach are compared with previous manually produced examples. The results indicate over 40% match between the automatic and manual approach, which is a good basis for further development. The comparison suggests that the automated approach works well for features and relationships that are expressed explicitly and consistently but begin to lose accuracy when applied to complex sentences. The comparison also suggests that the accuracy of the proposed automated approach can be improved by using a trained part-of-speech (POS) tagger, improved parsing grammar and an ontology.
SUPPORTING EARLY STAGES OF DESIGN METHOD VALIDATION - AN APPROACH TO ASSESS APPLICABILITY
Authors: Eisenmann Matthias , Grauberger Patric , Matthiesen Sven
Published: August 2021

Design method validation is an important research activity in method development. But the design method's applicability is often left out in validation, although it is a necessary step and it enables further validation steps. Currently, there is a lack of support for the assessment of design method applicability. We present an approach to provide support for iterative studies on three aspects of design method applicability. We evaluate the approach in a single case study. In the study, we investigate the applicability of a method for model building in analysis, in three iterative steps of the approach. Application of the approach produced valuable insights on the method applicability. The results show how aspects of applicability can be assessed using the presented approach. Therefore, the approach can contribute to the standardisation of design method validation, especially for early stages of validation, which is currently discussed in the community.
THE IMPORTANCE OF GENDER-AWARE DESIGN IN DIGITAL HEALTH WEARABLES: A CO-DESIGN STUDY FOSTERING SUN PROTECTION BEHAVIOUR IN YOUNG MEN
Authors: Khayamian Esfahani Bahar
Published: August 2021

The rise in the number of people living with long-term conditions is precipitating a shift towards the development of wearable technologies that can monitor our health remotely. This shift makes it possible to rethink the healthcare structure towards awareness and proactive prevention instead of treatment through empowering users, e.g. patients for self-management of their health. In a sector towards individual specialization and relying on personal healthcare management, design has a key role in user participation and engagement. This paper reports a co-design study that empowered the participants as designers to design human-centred interventions that foster sun protection behaviour in young men. The findings from this study show the following: 1) sun protection concepts to enhance young men's engagement in sun protection behaviour, 2) the integration of gender-aware design in digital health wearables contributes towards better user engagement in wearable technologies of the future.
TO SUPPORT IOT COLLABORATIVE EXPRESSIVENESS ON THE SHOP FLOOR
Authors: Aranda Muñoz Álvaro , Eriksson Yvonne , Yamamoto Yuji , Florin Ulrika , Sandström Kristian
Published: August 2021

The availability of new research for IoT support and the human-centric perspective of industry 4.0 opens a gap to support operators in unleashing their creativity so they can provide improvements opportunities with IoT technology. This paper presents a case-study carried out in four Swedish manufacturing companies, where four different workshops were facilitated to support operators in the conceptualization of manufacturing improvements with IoT technologies. The empirical material gathered during these workshops has been analyzed in five different reflective sessions and discussed in light of previous research from industry 4.0, operators, and IoT support. Results indicate that operators can collaboratively create conceptual IoT solutions and that expressiveness in communicating their ideas and needs using IoT technology is more relevant than technical aspects and details of their proposed IoT solutions. This technological expressiveness is identified as a necessary skill to be cultivated on the shop floor and can potentially contribute to making a more effective and socially sustainable industrial landscape in the future.

Published: August 2021

Prototyping is an essential activity in the early stages of product development. This activity can provide insight into the learning process that takes place during the implementation of an idea. It can also help to improve the design of a product. This information and the process are useful in design education as they can be used to enhance students' ability to prototype their ideas and develop creative solutions. To observe the activity of prototype development, we conducted a study on students participating in a 7-week course: Principles of Digital Fabrication. During the course, eight teams made prototypes and shared their weekly developments via internet blog posts. The posts contained prototype pictures, descriptions of their ideas, and reflections on activities. The blog documentation of the prototypes developed by the students was done without the researchers' intervention, providing essential data or research. Based on a review of other methods of capturing the prototype development process, we compare existing documentation tools with the method used in the case study and outline the practices and tools related to the effective documentation of prototyping activity.
TOWARDS A PEOPLE-FIRST ENGINEERING DESIGN APPROACH. A COMPREHENSIVE ONTOLOGY FOR DESIGNING INCLUSIVE ENVIRONMENTS
Authors: Fernandez Claudia , Zallio Matteo , Berry Damon , McGrory John
Published: August 2021

The world is ageing, and this change will strongly impact the design of products, services and environments. Notwithstanding the proliferation of research initiatives, guidelines, policies and regulations, there is still a significant gap and lack of a uniformed strategy to guide engineers, designers, and architects to design inclusive environments. This article explores and summarizes through a review of international regulations and standards, the requirements that design practitioners need to consider when designing accessible, inclusive, smart, age-friendly environments. With this explorative study, we reviewed documentation and developed a comprehensive ontology comprised of people and design related criteria aiming to support the design of inclusive, smart and accessible buildings. The ontology was created by interpreting the criteria through semantics used in peoplecentered design approaches, where people's needs and design requirements are two fundamental phases for designing inclusively.

The results are intended to enable researchers and practitioners to better identify clusters of accessibility and inclusion criteria to facilitate the study and the design of accessible, inclusive, smart, age-friendly environments.
TOWARDS FUNCTIONAL ARCHITECTURAL DECOMPOSITION OF CONSTRAINED LAYER INFLATABLE SYSTEMS
Authors: Benli Koray , Luntz Jonathan , Brei Diann , Kim Wonhee , Alexander Paul , Johnson Nancy
Published: August 2021

Pneumatically activated systems enable myriad types of highly functional inflatables employing a wide range of architectural approaches affecting their form and function, making systematic conceptual design difficult. A new architectural class of pneumatically activated systems, constrained layer inflatable systems, consists of hierarchically architected flat layers of thin airtight bladders that are internally and/or externally constrained to generate a variety of functionalities. The highly hierarchical architectural structure of constrained layer inflatable systems coincides with the hierarchy of produced functions, providing an opportunity for the development of a functional architectural decomposition, capturing the inherent relationship between architectural and functional hierarchies. The basis of the approach is conveyed through the design of an example constrained layer inflatable system. This approach empowers the systematic understanding of the interrelated architectural and functional breakdown of constrained layer inflatable systems, enabling designers to iteratively analyze, synthesize, and re-synthesize the components of the system improving existing designs and exploring new concepts.
UNDERSTANDING THE EMBEDDED CARBON CHALLENGES OF BUILDING SERVICE SYSTEMS
Authors: Hein Maria , Jones Darren Anthony , Eckert Claudia Margot
Published: August 2021

Energy consumed in buildings is a main contributor to CO2 emissions, there is therefore a need to improve the energy performance of buildings, particularly commercial buildings whereby building service systems are often substantially over-designed due to the application of excess margins during the design process.

The cooling system of an NHS Hospital was studied and modelled in order to identify if the system was overdesigned, and to quantify the oversizing impact on the system operational and embodied carbon footprints. Looking at the operational energy use and environmental performance of the current system as well as an alternative optimised system through appropriate modelling and calculation, the case study results indicate significant environmental impacts are caused by the oversizing of cooling system.

The study also established that it is currently more difficult to obtain an estimate of the embodied carbon footprint of building service systems. It is therefore the responsibility of the machine builders to provide information and data relating to the embodied carbon of their products, which in the longer term, this is likely to become a standard industry requirement.
UNDERSTANDING USERS AND PRODUCTS IN PRODUCT DEVELOPMENT: THE APPLICATION OF PRODUCT USAGE INFORMATION AND ITS CHALLENGES
Authors: Deng Quan , Wellsandt Stefan , Hribernik Karl , Thoben Klaus-Dieter
Published: August 2021

The need to understand users and products is one of the cores for product success. There are many ways to reach this understanding,such as,interviews and consumer cocreation. This study put a focus on the application of product usage information (PUI). Although amount of product-related information is available in the middle of a product's life, producers have not realized the full potential of these data in product development. The academic literature describes various use cases that outline how PUI supports this kind of understanding, and eventually benefits product development. Each of them provides fragmented information from certain perspectives. This diversity and the lack of systematic overview facilitates a fragmentation in the research of PUI usage in product development. To have an initial and unified overview of PUI's value on the understanding of users and products, this paper conducted a combination of systematic and descriptive review to form a sample with 12 papers. The result indicates that PUI increases producer's understanding about the product, its users and the context of usage. However, producers need to address several challenges if they want to apply PUI in product development successfully.
USER NEED-ORIENTED CONCEPT DEVELOPMENT OF AUTONOMOUS VEHICLES
Authors: Schockenhoff Ferdinand , König Adrian , Zähringer Maximilian , Lienkamp Markus
Published: August 2021

Vehicle concept development is a domain that has applied and detailed its process over decades. The megatrends of the 21st century of “automation” and “sharing” influence the vehicle concept in such a manner that this well-running process needs an update. The vehicle itself and the customer of the vehicle are changing and therefore the components of the vehicle and the input variables of the useroriented design of the vehicle concept must be changed as well. We present a development process for autonomous vehicle concepts to address these challenges. We are therefore analyzing the current definition of a vehicle concept and its development process. Based on a literature review of a selection of common design methodologies, we update this definition for autonomous vehicle concepts and present a development process that presents design concepts of autonomous vehicle in a user need oriented way. This includes the sharing of models since user needs could be fulfilled by more than one vehicle concept. We believe that the presented process can be a starting point for vehicle concept development of the 21st century.
CARDINAL WTRL: TECHNOLOGY MATURITY, SCHEDULE SLIPPAGE AND TREND FORECASTING.
Authors: Behdinan Kamran , Mishra Soumya Ranjan
Published: August 2021

Maturity assessments of technology is a crucial process to identify and acquire compatible technologies for a system’s development. However, being a complex and highly subjective process, the Government Accountability Office (GAO) has reported cost overruns and schedule slippages through the years. This study provides a unique Weighted Technology Readiness Level (WTRL) framework which utilizes cardinal factors to ascertain the maturity, schedule and trend of NASA’s 7 Technologies based on their maturity time. The framework utilizes MCDM methods to determine the cardinal complexity of each TRL. It allows the assimilation of other cardinal factors using a simple, open structure to track the overall technology maturity and readiness. Furthermore, this study highlights the importance of tailored TRL frameworks to determine the accurate cardinal coefficient of the said technology and the inferences derived otherwise. It eliminates several limitations of previous frameworks and compares against their performance using a verified statistical representation of processed data.
CHINESE PRODUCT-SERVICE SYSTEM INNOVATIONS ENABLED VIA GOVERNMENTAL POLICIES: THE E-SCOOTER CASE
Authors: Yan Zhang , Larsson Tobias , Larsson Andreas
Published: August 2021

Together with increasingly saturated and commoditized global markets companies are driven to shift their business focus, adopting a strategy where customer perceived value is in the spotlight, and where products are bundled with services to offer Product-Service Systems (PSS).

In this research we study the emergence of PSS solutions in the Chinese market via a selected case study on e-scooters, based on the governmental decision to ban fossil-fuel scooters in the late 90s and how this has spurred both a fossil-to-electric transformation and a product-to-function transformation.

As seen in this research PSS is also an approach that is working well in the Eastern society and especially in China, based on governmental policies. It is gradually being adopted and applied in local industries significantly by China's leading internet companies (Didi, Alibaba etc). The PSS concept represented by e-bike cases in China has gradually penetrated into different industries. With governmental decisions as the key turn-point, it can be seen in practice and development that China's related service industry is using e-bike PSS to carry out the new business model from selling e-bikes to providing service-oriented solutions.
CLASSIFICATION OF TRANSFORMABLE PRODUCTS BASED ON CHANGES IN PRODUCT FORM AND FUNCTION
Authors: Lee Haebin , Tufail Muhammad , Kim KwanMyung
Published: August 2021

The sentence “form follows function” is the best expression of the relationship between form and function of a product in modern product design. This implies that the form is essential to implement the function while it should be optimized and minimized for the function. Unlike general products, transformable products are designed with the intention to change the function and form of the product according to the situation. This paper presents the types and characteristics of transformable products determined by Phase Model we introduced. We collected 147 transformable product cases and analyzed them according to the change of functions and forms in each product. As a result, we classified the transformable products into four types: partial transformable product, multi-form product, multi-function product and full transformable product. We found that each type has unique characteristics with potential to drive innovation in product design field.
A DATA-DRIVEN APPROACH TO USER-EXPERIENCE-FOCUSED MODEL-BASED ROADMAPPING FOR NEW PRODUCT PLANNING

Published: August 2021

User experience (UX) focused business needs to survive and plan its new product development (NPD) activities in a highly turbulent environment. The latter is a function of volatile UX and technology trends, competition, unpredictable events, and user needs uncertainty. To address this problem, the concept of design roadmapping has been proposed in the literature. It was argued that tools built on the idea of design roadmapping have to be very flexible and data-driven (i.e., be able to receive feedback from users in an iterative manner). At the same time, a model-based approach to roadmapping has emerged, promising to achieve such flexibility. In this work, we propose to incorporate design roadmapping to model-based roadmapping and integrate it with various user testing approaches into a single tool to support a flexible data-driven NPD planning process.
CONCEPTUAL DESIGN FOR ASSEMBLY IN AEROSPACE INDUSTRY: SENSITIVITY ANALYSIS OF MATHEMATICAL FRAMEWORK AND DESIGN PARAMETERS
Authors: Formentini Giovanni , Favi Claudio , Cuiller Claude , Dereux Pierre-Eric , Bouissiere Francois , Jurbert Cédric
Published: August 2021

One of the most challenging activity in the engineering design process is the definition of a framework (model and parameters) for the characterization of specific processes such as installation and assembly. Aircraft system architectures are complex structures used to understand relation among elements (modules) inside an aircraft and its evaluation is one of the first activity since the conceptual design. The assessment of aircraft architectures, from the assembly perspective, requires parameter identification as well as the definition of the overall analysis framework (i.e., mathematical models, equations).

The paper aims at the analysis of a mathematical framework (structure, equations and parameters) developed to assess the fit for assembly performances of aircraft system architectures by the mean of sensitivity analysis (One-Factor-At-Time method). The sensitivity analysis was performed on a complex engineering framework, i.e. the Conceptual Design for Assembly (CDfA) methodology, which is characterized by level, domains and attributes (parameters). A commercial aircraft cabin system was used as a case study to understand the use of different mathematical operators as well as the way to cluster attributes.

Published: August 2021

Process models are among the principal artefacts used for managing design projects. However, the selection of effective modelling approaches can be difficult for design project managers, given that a plethora of tools exists for various modelling purposes. In addition to date no systematic approach for the assessment and selection of process modelling approaches is available to practitioners. This paper presents the development of criteria for benchmarking and selecting different process modelling tools. The results are based on three elements. (1) In a four-hour workshop undertaken by the Design Process SIG of the Design Society, bringing together around 20 international researchers and practitioners in design process modelling, an initial set of 58 criteria were brainstormed and consolidated during the workshop and in follow-up meetings. (2) The consolidated criteria were then compared with literature. The finalised criteria list was then validated by external experts in industry (3). The resulting list of 12 criteria provides a sound basis for practitioners to support a systematic selection of process modelling approaches. Further, it lays the foundation of a benchmarking tool, which is subject to future work.
DATA-DRIVEN CREATIVITY: COMPUTATIONAL PROBLEM-EXPLORING IN ENGINEERING DESIGN
Authors: Obieke Chijioke C. , Milisavljevic-Syed Jelena , Han Ji
Published: August 2021

Creativity is required in engineering design. It is required in the aspects of problem-solving - conceptualizing a new solution to a problem, and problem-exploring - conceptualizing a new problem. Studies show that, in both aspects, creativity is a difficult task in practice. The aim of this study is to support the engineering design community by easing the difficulty in the problem-exploring practice. To achieve this, a computational problem-exploring (CPE) model is developed to mimic how design engineers identify a valid design problem. Consequently, a CPE tool - Pro-Explora V1 is developed based on the CPE model. The CPE model consists of a synergy of emergent computational technologies including data retrieval and machine learning. A Markovian model is employed in the CPE model to enable a data-driven random process for exploring design problems. In pilot test, Pro-Explora V1 generated some engineering design-related problems which are meaningful, unique, and could not be distinguished from naturally generated ones. It provides support to design engineers in problem-exploring at the early stage in engineering design. This study contributes to the global effort towards data-driven processes in the fourth industrial revolution.
DERIVATION OF CRITERIA FOR ASSESSING SOLUTION PRINCIPLES CONFORMAL FOR ADDITIVE MANUFACTURING
Authors: Tüzün Gregory-Jamie , Garrelts Enno , Roth Daniel , Binz Hansgeorg
Published: August 2021

Additively manufactured final products and components are not always tailored to the additive manufacturing (AM) process, but they need to be in order to exploit the many advantages and potentials that AM provides. Therefore, an appropriate AM design should be targeted, which reduces the necessary iterations in the developing process of AM products. Although there is a large number of existing literature on the Design for Additive Manufacturing (DfAM), designers usually lack criteria in order to assess AM-conformity in conceptual design. In this paper, we provide a basis for the assessment of solution principles regarding their conformity for additive manufacturing.

First, existing literature on DfAM and AM products is reviewed comprehensively to derive criteria for the AM-conformity of solution principles. Subsequently, the correlations between these criteria are identified including the interdependencies to be considered when assessing AM-conformity. A basis for assessment is created, which offers designers early support in the development of AM-conformal designs.
DESIGN FOR CONTINUOUS USE OF PRODUCT-SERVICE SYSTEMS: A CONCEPTUAL FRAMEWORK
Authors: Nemoto Yutaro , Dhiman Hitesh , Röcker Carsten
Published: August 2021

Product-service systems (PSSs) have attracted researchers in engineering design for the past decades. Recent advances in digital technologies have expanded the potential functionalities that PSSs could deliver and designers' repertoire of tools and techniques to make new value propositions. The key to the success of new value propositions is to achieve customer acceptance and continuous use. However, little is known about the precise routes by which customers accept and use PSSs over time and its dynamics. This conceptual study aims to provide an enhanced view of customer acceptance and continuous use of PSSs by integrating multiple theories and literature streams. In this paper, we suggest three propositions based on the key concepts found in our literature review—well-being, trust and control—, and illustrate a conceptual framework that represents the dynamics of customer acceptance and continuous use of PSSs. Based on the proposed framework, we outline further research questions that could advance our knowledge about design for continuous use of PSSs.
DESIGN FOR FUTURE VARIETY TO ENABLE LONG-TERM BENEFITS OF MODULAR PRODUCT FAMILIES
Authors: Greve Erik , Fuchs Christoph , Hamraz Bahram , Windheim Marc , Krause Dieter
Published: August 2021

By developing and using modular product families, large savings can be achieved through reuse and combinability along the entire value chain of a company. Since these potentials often have a very long-term character, the lifetime of a modular product family should be as long as possible. Change drivers, such as changing customer and production requirements, however, result in changes having to be made to the initially developed modular product family, which not only causes a great effort but also prevents the long-term benefits from being fully exploited. With the Change Allocation Model, we introduce a tool that makes it possible to align the essential future changes to the product architecture and to identify and redesign the change-critical components taking into account the existing component variety of the product family. This enables future changes in variety to be considered in the product architecture and a future robust modular product family to be developed. The new visualization is illustrated using the example of a product family of pressure regulating valves and is finally discussed with regard to further potentials and challenges.
The Politicization of Immigration and Integration at the Subnational Level: Electoral Campaigns in Ontario and Quebec
Authors: Gagnon Audrey , Larios Lindsay
Published: August 2021

Open political debate on immigration and integration policies (IIP) among Canadian political parties has been relatively limited. As Canada's immigration and integration systems become more decentralized, what about political debates about IIP in Canadian provinces? This article examines how IIP evolved across time by focusing on political parties’ claims, frames and pledges in party platforms and newspapers, using the cases of Ontario and Quebec. In Ontario, IIP were primarily framed as an economic and social resource. However, following the event of 9/11, new frames began to be introduced, contributing to a heightened salience and polarization. In contrast to Quebec, however, this politicization was not sustained. In Quebec, IIP were only marginally a matter of debate until the mid-2000s. This changed following the Hérouxville event, as these topics became salient, and dominant frames of immigration as economic and social resources were challenged by those of immigration as economic and cultural threats.
African Population History: Contributions of Moral Demography
Authors: Walters Sarah
Published: August 2021

Improving knowledge about African historical demography is essential to addressing current population trends and achieving deeper understanding of social, economic, and political change in the past and present. I use census and parish register data from Tanganyika to address the origins of twentieth-century population growth, to describe how major changes in fertility and child mortality began in the 1940s, and to emphasise the significance of the large rise in fertility between the 1940s and 1970s. Through this work and my wider survey of parish registers in Malawi, Uganda, Tanzania, and Zambia, I consider the relationships between power, evidence, and meaning in these data sources. Alongside the macro gaps in Africa's population history are significant microsilences — lacunae in the sources and data which reflect the hegemonic structures within which they were produced. I suggest a moral demography approach to their analysis, borrowing from the reflexive and dialectic method found in studies of moral economy.

Published: August 2021

This study aimed to determine the requirements of standardized ileal digestible (SID) methionine (Met) + cysteine (Cys) of 15–30 kg barrows, maintaining or increasing the 1:1 ratio between SID Met and SID Cys. Seventy crossbred barrows averaging 15.2 ± 0.54 kg of live weight were allotted in a randomized block design 2 × 3 + 1 factorial scheme, with five replicates and two animals per pen. Treatments consisted of maintaining or increasing the 1:1 ratio between SID Met and SID Cys, three levels of SID Met + Cys (5.8, 6.4 and 7.0 g/kg) and a basal diet containing the lowest SID Met + Cys level (5.2 g/kg), formulated to provide a 1:1 ratio of SID Met (2.6 g/kg) and SID Cys (2.6 g/kg). Performance, blood parameters, longissimus dorsi muscle depth, backfat thickness and S–S linkages in the bristles were evaluated. The best average daily gain was estimated at 6.61 g/kg of SID Met + Cys, without maintaining the 1:1 ratio between sulphur amino acids (SAA). The daily intake of SID Met + Cys increased due to dietary SID Met + Cys levels, maintaining or increasing the same ratio between SAA. Plasma glucose increased and total cholesterol decreased according to SID Met + Cys levels, without maintaining the same ratio between the SAA. The requirement of SID Met + Cys for 15–30 kg barrows was 6.61 g/kg (7.88 g/day) for an optimum average daily gain, with no need to maintain the same ratio between the SAA.

Abstract. Introduction: The COVID-19 pandemic has impacted individuals, communities, and whole populations. Experts across many different fields contributed their time and efforts in different ways to respond to the pandemic. Psychologists working in healthcare provided support and led many initiatives, both regionally and nationally. However, it is unknown how this has differed across Europe and its full range of activities and contributions. Aim: The current study is a survey of European member associations of EFPA, carried out to understand the current contributions and the impact those psychology contributions have had on the COVID-19 pandemic response, to share lessons learned, and to propose a roadmap for the future. Results: Overall, our study highlights how psychological expertise was integrated into many countries’ policy/decision-making, action-planning, caregiving, and the promotion of health and well-being to health professionals and the general public. Even in places where psychologists were not directly integrated into governmental systems, they played an important role in responding to this pandemic by providing their services and empirical knowledge. Discussion: Many psychologists possess the skills and tools to adapt their practice to the digital provision of services and to provide a continuity of care during the pandemic. Research carried out by psychologists has contributed important and new knowledge on pandemic effects, consequences, and interventions; yet, more research financial support is needed. We make recommendations for augmenting psychologists’ contributions in the future. In a global health crisis, where the main possible treatment is a preventive approach concentrated on sustainable behavior change, psychologists should be included every step of the way – they can make a difference.

Abstract. Background: Under the new psychotherapy law in Germany, standardized patients (SPs) are to become a standard component in psychotherapy training, even though little is known about their authenticity. Objective: The present pilot study explored whether, following an exhaustive two-day SP training, psychotherapy trainees can distinguish SPs from real patients. Methods: Twenty-eight psychotherapy trainees ( M = 28.54 years of age, SD = 3.19) participated as blind raters. They evaluated six video-recorded therapy segments of trained SPs and real patients using the Authenticity of Patient Demonstrations Scale. Results: The authenticity scores of real patients and SPs did not differ ( p = .43). The descriptive results indicated that the highest score of authenticity was given to an SP. Further, the real patients did not differ significantly from the SPs concerning perceived impairment ( p = .33) and the likelihood of being a real patient ( p = .52). Conclusions: The current results suggest that psychotherapy trainees were unable to distinguish the SPs from real patients. We therefore strongly recommend incorporating training SPs before application. Limitations and future research directions are discussed.
Forschungsethische Standards im Kontext der Optimierung pädagogischer Praxis durch Forschung

Zusammenfassung. Der Beitrag setzt sich mit der Frage auseinander, was Optimierung im Kontext der frühpädagogischen Forschung bedeutet und woran sie in der Forschungspraxis zu erkennen ist. Konkret geht es um die Eruierung der (ergänzenden) forschungsethischen Standards als Qualitätsmerkmal „optimaler“ empirischer Sozialforschung im Rahmen von Forschungsprojekten in Kitas. Die Ergebnisse des Projekts „Forschung trifft Kita“ werden dazu genutzt, das Optimierungsproblem anhand der kritischen Einschätzungen von pädagogischen Fach- und Leitungskräften in der deutschlandweiten Online-Befragung ( N = 1.200) zur Forschung in Kitas zu identifizieren und zu beschreiben.

Abstract. Individuals differ in the extent to which they perceive threat imposed by out-groups like migrants. An established distinction in intergroup threat research is between symbolic and realistic threat. While symbolic threats concern a perceived menace against societal values, realistic threats jeopardize in-group members’ well-being more directly. Typically applied realistic threat conceptions explicitly include the aspect of physical integrity, but most empirical research captures only realistic economic threats, arguably also due to a lack of appropriate measures. Therefore, we have developed the Perceived Realistic Physical Threat scale (PRPT) with samples from Germany and the UK (total N = 1,391). Moreover, we conducted follow-up analyses with data from a subsample ( N = 473) of the initial UK sample. Factor analyses indicated an 8-item one-factorial solution for the PRPT scale. We further identified measurement invariance across samples and over time and stability across 21 months. We found convincing evidence for its convergent and divergent validity and for its predictive and, importantly, incremental validity, above and beyond the prediction of relevant criteria by other threat types. The PRPT scale appears to be a distinct, comprehensive, and psychometrically sound measure of perceived realistic physical threat, complementing the existing body of available measures.

Abstract. In the context of the COVID-19 pandemic, motherwork has increased. Mothers, including in Guatemala, have taken on expanded responsibilities of virtual schooling and keeping the family safe and healthy, in addition to prepandemic familial and professional contributions. Twelve Guatemalan mothers of children under age 7 were interviewed about how they negotiated the pandemic; data were coded using thematic analysis and consensual qualitative research frameworks. Analysis revealed six themes: daily stressors, fostering children's development, implementing coping strategies, utilizing technology, establishing closer relationships, and achieving personal and occupational growth. Guatemalan mothers tapped into existing ideologies of motherhood, relied on traditional values of Guatemalan culture – faith, family, and gratitude – prioritized their children's well-being, and found unexpected benefits. Social policies that specifically address women's conditions, agency, and strengths could forward achievement of Sustainable Development Goal 5, Gender Equality, in Guatemala.

Abstract. Modern slavery is a significant global human rights crisis that disproportionately affects women and girls, and research indicates that the COVID-19 pandemic has exacerbated existing vulnerabilities to exploitation. Early evidence suggests that the pandemic has disproportionately affected women and girls, including an increase in lack of access to family planning and adequate sexual and reproductive care and an increase in maternal mortality rates. Additionally, the pandemic has instigated a reduction in economic opportunities and access to education for women and girls and increased violence against women. For this study, regression analysis was used to examine country-level data from 197 UN member countries. Predictor variables included indicators reflecting key areas addressed by UN Sustainable Development Goal 5 (SDG-5): gender inequality, educational and economic opportunities for females, women's leadership, gendered violence, and women's health. SDG-5 calls for gender equality and empowerment of women and girls. The criterion variable was the estimated prevalence of modern slavery across UN countries. Regression analysis revealed significant results across all models. Literacy rates and expected years of schooling for females, femicide, lifetime prevalence of violence, and several indicators of women's health were found to be strongly and significantly related to increased estimated prevalence of modern slavery. Furthermore, we propose that the pandemic has increased vulnerability to exploitation for women and girls by regressing progress across all areas addressed by SDG-5.
