ANALYSIS OF THE CORRELATION BETWEEN AGILE TEAM MATURITY AND STANDARDISED KEY PERFORMANCE INDICATORS IN AUTOMOTIVE DEVELOPMENT
Authors: Scharold Franziska , Schrof Julian , Paetzold-Byhain Kristin 
Published: June 2023

AbstractThe application of agile development methods in response to increasing market dynamics and product complexity is a key lever in the automotive industry. Agile methods originally come from the software industry and enable fast, flexible and customer-oriented product development. These methods are also increasingly being used in hardware development. However, the evaluation of the benefits of agile methods in the context of automotive development has been primarily subjective. The publication aims to present a first data-based approach to objectify the benefits of agile methods in automotive development by highlighting the effects in the quality of collaboration within teams. A standardised procedure is therefore designed and presented. On the one hand, a model for measuring the agile maturity of teams is described. On the other hand, the quality of collaboration within a team is examined in different aspects using standardised key performance indicators. Based on the proposed procedure, a strong positive correlation was found between the considered key performance indicators of the quality of collaboration and the agile maturity of the development teams within the investigated organisation.
BARRIERS LEADING TO BUILDING SERVICES OVERDESIGN
Authors: Jones Darren Anthony , Eckert Claudia Margot 
Published: June 2023

AbstractThe research of this paper provides a useful insight into the many barriers leading to building services overdesign, within the context of NHS hospitals. The issue of overdesign in building services is a systemic problem, whereby numerous contributing factors manifest into an issue that inevitably leads to poor system performance and excess costs. A key factor leading to oversizing is the excessive and uncoordinated application of design margins across the various stages of a building services project. Poor communication between project stakeholders is another significant barrier that inhibits the distribution of information between design groups; unknown requirements, system redundancy and poor system specifications further add to the problem. There are many complex interrelationships associated with the building service design process in hospitals, with external stakeholders adding to the complexity. This points to the importance of effective communication between stakeholders and clear contractual terms between NHS Trusts and external private sector organisations. Many of the barriers identified within this paper are by no means limited to building service systems but also impact on a range of other engineering disciplines.
BRIDGING DESIGNER-USER GAP WITH A VIRTUAL REALITY-BASED EMPATHIC DESIGN APPROACH: CONTEXTUAL INFORMATION DETAILS
Authors: Hu Xinhui , Casakin Hernan , Georgiev Georgi V. 
Published: June 2023

AbstractWithout shared experiences, empathy gaps between designers and users are difficult to bridge. Advancing Virtual Reality (VR) has shed new light on this regard by enabling designers to simulate and experience their users' living scenarios in a virtual environment (VE). However, implementing VR-based empathetic design approach requires dealing with critical design questions, such as: (1) whether VR operators can develop empathy for unfamiliar user groups solely based on objective experience and (2) whether VR operators can utilize task-irrelevant contextual information in the VEs. To explore these issues, we designed an experiment based on two VEs with varying levels of detail that simulated the scenes viewed by people with red-green color vision deficiency (CVD). Participants were randomly assigned to either detail-rich or detail-simple VEs to complete neutral item-searching tasks. Results indicate that objective and neutral experience alone cannot elicit empathy towards users, and VR operating designers will utilize task-irrelevant contextual information.
A CRITICAL APPRAISAL OF MIXED REALITY PROTOTYPING TO SUPPORT STUDIO DESIGN EDUCATION
Authors: Ranscombe Charlie , Zhang Wendy , Snider Chris , Hicks Ben 
Published: June 2023

AbstractMixed Reality (MR) technologies are widely available and applied in a variety of design and engineering applications. MR prototypes capture the respective benefits of physical and digital prototypes by merging these domains saving the time and resources required to create them. This advantage is compelling in the context of design education where tight time and resource constraints exist. However, it is known that new digital prototyping tools can cause problems for students applying appropriate prototyping tools during practice-based studio design projects. Our paper contributes a systematic appraisal of MR prototyping's proposed dimensions value against constraints and issues in design studio education. This highlights MR Visualisation and Knowledge Management dimensions as most readily realised in education. Recommendations are then reflected on via an illustrative case study into the implementation of MR prototyping via these dimensions. Reflections corroborate the value proposition, but also highlight a need for further research exploring activities to scaffold MR prototyping to further support reflective design thinking.

Published: June 2023

AbstractProduct-service systems (PSS) are one of the business models that can promote circular economy and sustainability; however, to design this kind of solution, holistic approaches must be used, integrating different areas of knowledge. Thus, this study proposes a conceptual solution based on the PSS business model to the problem of reverse logistics of coffee capsules, through the application of the Requirements Engineering method for Sustainable PSS design, with a focus on the initial phase. With an emphasis on the business model and value proposition, a conceptual solution was developed to promote the circularity of the capsule chain based on the analysis of the main stakeholders' needs. The value proposition of the PSS solution for the issue of coffee capsules was described as the “cocreation of sustainable value to stakeholders to foster the circularity of the chain”, considering consumer involvement through education and rewards in product disposal processes. The results reinforce the need to integrate critical stakeholders to add the desired value in creating a sustainable PSS solution and the need to pivot the business model during the solution development process.
CIRCULARITY OF PLASTICS THROUGH ECODESIGN: THE CASE OF FRENCH WEEE
Authors: Nève Nicolas , Charbuillet Carole , Pompidou Stéphane , Perry Nicolas 
Published: June 2023

AbstractWhile innovation in waste treatment processes continue to advance, plastics are still often put aside in comparison to other materials. It is especially the case for WEEE-plastics: as they are included in complex equipment, their recovery is disregarded, in aid of critical metals and rare earths. The recycling of plastics is hindered by the low re-integration rate of these materials, due to concerns around their quality and their availability. Ecodesign of EEE thus seems to be a robust solution. This paper details two approaches to assess product design, by respectively evaluating the product recyclability and the implementation of predefined ecodesign guidelines. Based on these methods, the construction of a quality standard for recycled plastics in France is presented. The definition of the quality includes mechanical properties, but chemical, logistics, and regulatory aspects are also at stake. Eventually, ecodesign indexes and indicators are selected, and a method for their formal construction is proposed. The goal of this study is to provide ways to assess the overall quality and usability of recycled plastics, along with design for circularity methods to integrate them in new manufactured products.

Abstract
Plastics pollute all environmental compartments because of human activities and mismanagement. Public perceptions and knowledge about plastic pollution differ among individuals and across different jurisdictions. Targeted survey-based research tools can help measure consumer awareness about the impacts of mismanaged plastics and help identify trends and solutions to reduce plastic use and plastic pollution. This review primarily focused on survey-based research from presenters at the scientific track session TS-2.15 Plastic Pulse of the Public at the 7th International Marine Debris Conference (www.7imdc.org) and supplemented by contemporary literature. Survey-based research helps provide new insights about public opinions related to the pervasiveness of plastic pollution. This review includes results about consumer use and perceptions of plastic pollution impacts from diverse studies from nine countries including Ghana, Kenya, Bangladesh, Pakistan, United States, Canada, Norway, Germany, and United Kingdom. Overwhelmingly, public perceptions and consumer awareness of the negative impacts of plastic pollution were extremely high, regardless of geographic location. Awareness about the environmental impacts of plastic waste and plastic pollution was highest within younger, white, female, and well-educated demographic groups. However, differences were observed in public attitudes toward willingness to pay for sustainable alternatives, end-of-life plastic uses, unintended consequences, recycling, and mismanagement.
UPPER BOUNDS ON THE SEMITOTAL FORCING NUMBER OF GRAPHS

Published: June 2023

AbstractLet G be a graph with no isolated vertex. A semitotal forcing set of G is a (zero) forcing set S such that every vertex in S is within distance 2 of another vertex of S. The semitotal forcing number
$F_{t2}(G)$
is the minimum cardinality of a semitotal forcing set in G. In this paper, we prove that it is NP-complete to determine the semitotal forcing number of a graph. We also prove that if
$G\neq K_n$
is a connected graph of order
$n\geq 4$
with maximum degree
$\Delta \geq 2$
, then
$F_{t2}(G)\leq (\Delta-1)n/\Delta$
, with equality if and only if either
$G=C_{4}$
or
$G=P_{4}$
or
$G=K_{\Delta ,\Delta }$

Decolonizing Research on the Carceral in Canadian Political Science
Authors: Mussell Linda 
Published: June 2023

AbstractIn Canada, there is renewed attention to the violence experienced by Indigenous peoples in residential schools, by police, through hyper-imprisonment and child removal, in hospitals, and in the contemporary education system. All of these issues are interlinked and outcomes of the carceral state—defined as the policing, monitoring, surveillance, criminalization and imprisonment of people, especially Indigenous and other racialized peoples. In this article, I define and illustrate what the carceral state looks like in Canada. I articulate the current approach to studying the carceral in political science, note the paucity of research in the Canadian context and show where attention has been cast previously. I describe an improved approach to studying the carceral, arguing that a decolonized approach to studying the carceral must be relational and abolitionist, seeking to reduce and eliminate the use of carceral interventions.
Frankfurt Cases and Alternate Deontic Categories
Authors: Kahn Samuel 
Published: June 2023

AbstractIn Harry Frankfurt’s seminal “Alternate Possibilities and Moral Responsibility,” he advances an argument against the Principle of Alternate Possibilities: if an agent is responsible for performing some action, then she is able to do otherwise. However, almost all of the Frankfurt cases in this literature involve impermissible actions. In this article, I argue that the failure to consider other deontic categories exposes a deep problem, one that threatens either to upend much current moral theorizing or to upend the relevance of Frankfurt cases.
A note on virtual duality and automorphism groups of right-angled Artin groups
Authors: Wade Richard D. , Brück Benjamin 
Published: June 2023

AbstractA theorem of Brady and Meier states that a right-angled Artin group is a duality group if and only if the flag complex of the defining graph is Cohen–Macaulay. We use this to give an example of a RAAG with the property that its outer automorphism group is not a virtual duality group. This gives a partial answer to a question of Vogtmann. In an appendix, Brück describes how he used a computer-assisted search to find further examples.
Increased plane identification precision with stereo identification
Authors: Ji Junjie , Zhao Jing-Shan 
Published: June 2023

AbstractStereo vision allows machines to perceive their surroundings, with plane identification serving as a crucial aspect of perception. The accuracy of identification constrains the applicability of stereo systems. Some stereo vision cameras are cost-effective, compact, and user-friendly, resulting in widespread use in engineering applications. However, identification errors limit their effectiveness in quantitative scenarios. While certain calibration methods enhance identification accuracy using camera distortion models, they rely on specific models tailored to a camera’s unique structure. This article presents a calibration method that is not dependent on any particular distortion model, capable of correcting plane position and orientation identified by any algorithm, provided that the identification error is biased. A high-precision mechanical calibration platform is designed to acquire accurate calibration data while using the same detected material in real measurement scenarios. Experimental comparisons confirm the efficacy of plane pose correction on PCL-RANSAC, with the average relative error of distance reduced by 5.4 times and the average absolute error of angle decreasing by 41.2%.
Experience of financial challenges, retirement concerns, and planning: evidence from representative samples of workers in 16 countries
Authors: Innocenti Stefania , Clark Gordon L. , McGill Sarah 
Published: June 2023

AbstractWe examine whether an individual's inability to save in the last 12 months affects the extent to which they are concerned about their future financial security and their propensity to plan for retirement. We use an original survey based upon representative samples of working individuals in 16 countries. We show that individuals who were unable to save over the 12-month period prior to the survey are less likely to consider well-being in retirement as their major financial concern. They are also less likely to invest in supplementary pension funds than those who were able to accumulate savings. We provide evidence that these findings are robust under several specifications and are mediated by respondents' perceived income prospects and assessment of their current financial situations.
Psychedelic medicines for end-of-life care: Pipeline clinical trial review 2022
Authors: Jing Xuepeng , Hoeh Nicholas R. , Menkes David B. 
Published: June 2023

AbstractObjectivesPeople with terminal illnesses often experience psychological distress and associated disability. Recent clinical trial evidence has stimulated interest in the therapeutic use of psychedelics at end of life. Much uncertainty remains, however, mainly due to methodological difficulties that beset existing trials. We conducted a scoping review of pipeline clinical trials of psychedelic treatment for depression, anxiety, and existential distress at end of life.MethodsProposed, registered, and ongoing trials were identified from 2 electronic databases (ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform). Recent reviews and both commercial and non-profit organization websites were used to identify additional unregistered trials.ResultsIn total, 25 studies were eligible, including 13 randomized controlled trials and 12 open-label trials. Three trials made attempts beyond randomization to assess expectancy and blinding effectiveness. Investigational drugs included ketamine (n = 11), psilocybin (n = 10), 3,4-methylenedioxymethamphetamine (n = 2), and lysergic acid diethylamide (n = 2). Three trials involved microdosing, and fifteen trials incorporated psychotherapy.Significance of resultsA variety of onging or upcoming clinical trials are expected to usefully extend evidence regarding psychedelic-assisted group therapy and microdosing in the end-of-life setting. Still needed are head-to-head comparisons of different psychedelics to identify those best suited to specific indications and clinical populations. More extensive and rigorous studies are also necessary to better control expectancy, confirm therapeutic findings and establish safety data to guide the clinical application of these novel therapies.
Gender differences in cancer spousal caregiving: A systematic review
Authors: Ng Janet H.Y. , Luk Bronya H.K. , Lee Natalie P.M. 
Published: June 2023

AbstractObjectivesCancer does affect not only the lives of the patients but also that of their spouses. The aims of this systematic review are to (i) explore the gender differences in the impact of caregiving for cancer on spousal caregivers, (ii) facilitate the conceptual understanding of gender differences in caregiving, and (iii) identify directions for future research and clinical practice targeting spousal caregivers.MethodsA comprehensive search was conducted of the electronic databases of MEDLINE, PsycINFO, EBSCO, and CINAHL Plus for papers published in English between 2000 and 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to identify, select, appraise, and synthesize the studies.ResultsA total of 20 studies from seven countries were reviewed. Findings of the studies were presented using the biopsychosocial model. Spousal caregivers of cancer patients suffered from physical, psychological, and socioeconomic morbidities, with female spousal caregivers reporting a higher level of distress. The gendered positioning of spousal caregivers in the societal context had further brought about over-responsibility and self-sacrifice among women.Significance of resultsThe gendered positions of cancer spousal caregivers further illustrated the gender differences in the caregiving experiences and consequences. Health-care professionals in routine clinical practice should be proactive in identifying physical, mental, and social morbidities among cancer spousal caregivers, particularly female ones, and providing timely interventions. Health-care professionals should recognize the pressing need for empirical research, political engagement, and action plans to address the health status and health-related behaviors of patients’ spouses along the cancer trajectory.
The Cumulative and Damaging Effects of Discrimination
Authors: Spencer Breauna Marie 
Published: June 2023

AbstractThis study examines the racialized and gendered experiences of Black men (N = 20) from elementary school through graduate school. The Black men featured in this article are current STEM doctoral students and were asked to reflect on their K-12 and undergraduate STEM experiences as well as their current experiences as graduate students. Findings conclude that Black men, as children and teens, experienced gendered racism in their STEM courses, which included a severe lack of racial representation of Black scientists, leading them to believe that they could not become scientists in their respective disciplines. At the undergraduate level, Black men encountered racial stereotyping and were self-conscious of their gender and race due to being underrepresented in their STEM courses. And at the doctoral level, Black men deal with psychological health issues due to the racism-related stressors they experience on campus, along with feeling compelled to be the spokesperson for Black students at their respective college campuses.
Energy Justice and the Principles of Article 194(1) TFEU Governing EU Energy Policy
Authors: Kaschny Laura 
Published: June 2023

AbstractRecent geopolitical and environmental events have created a new urgency for a just energy transition and a socially inclusive modernization of the energy sector. This article critically evaluates the extent to which Article 194(1) of the Treaty on the Functioning of the European Union (TFEU), as the competence provision of EU energy law, is congruent with the energy justice framework emerging from social sciences. It establishes the substantive scope and justiciability of Article 194(1) TFEU, including the legal principles and so-called ‘guiding principles’ of the provision relating to the internal market, environmental protection, and energy solidarity. The article analyzes the potential and shortcomings of Article 194(1) TFEU in contributing to more equitable decision-making processes in EU energy law. It concludes by evaluating the provision as a regulatory instrument that facilitates the (re)balancing of competing interests of the energy sector. This research further concludes that social considerations of energy justice cannot be sufficiently addressed through Article 194(1) TFEU.
Adaptation of a Thermorheological Lava Flow Model for Venus Conditions

Published: June 2023

AbstractActive volcanism was (and potentially still is) an important process that shapes the Venus surface and its detection is a primary goal for the planned VERITAS and EnVision missions. Therefore, understanding lava flow emplacement and timing on Venus is important. We adapt the terrestrial PyFLOWGO thermorheological model to Venus conditions to assess the effects on channelized lava flow propagation. We first initiate the model with terrestrial basaltic parameters and progressively adapt it to Venusian conditions in five steps: (a) gravity, (b) ambient atmospheric temperature, (c) specific heat capacity and wind speed, (d) atmospheric density, and (e) coupled convective and radiative heat flux. Compared to Earth, the slightly lower gravity on Venus resulted in a lower flow velocity, a higher crust coverage, and a very minor increase in flow length (0.1%). Increasing the ambient atmospheric temperature reduced heat loss and produced a (77%) longer flow; whereas next accounting for the atmospheric specific heat capacity and wind speed increased the flow length slightly more (81%). However, increasing the atmospheric density resulted in a shorter lava flow (13%) due to more efficient cooling. Finally, accounting for coupled convective and radiative heat loss due to the strong CO2 infrared absorption resulted in an increase of the flow length (∼75%). Although the model applies only to channelized, cooling‐limited flows, these results reveal that for the same effective effusion rate and topography, a Venusian lava flow travels a longer distance than the equivalent flow on Earth and its cooling should be detectable by future orbital instruments.
