Academic Integrity Through a SoTL Lens and 4M Framework: An Institutional Self-Study
Authors: Kenny Natasha , Eaton Sarah Elaine 
Published: March 2022

AbstractInstitutions are placing increased emphasis on the importance of academic integrity. Suffusing a culture of integrity is complex work. Influencing academic cultures (including the shared norms, values, behaviours and assumptions we hold) requires impact across multiple organization levels, stakeholders, structures and systems. These dimensions can be influenced by working with individual instructors, learners and staff (micro), across departments, faculties, networks and working groups (meso), through to the institution (macro), and disciplinary, national and international levels (mega). Akin to nurturing strong teaching and learning cultures communities and practices, institutions tend to support change at the institutional (vision, policies, structures) and individual levels (targeted programs to develop expertise). Less focus has been placed on how we establish strong networks of support and knowledge-sharing to influence decision-making, action, and change at the meso and mega levels. In this chapter we offer an institutional self-study of academic integrity through a scholarship of teaching and learning (SoTL) lens. Informed by the 4M (micro, meso, macro, mega) framework, we examine how integrity is upheld and enacted at each level. We examine both formal and informal approaches to academic integrity, looking at how a systematic, multi-stakeholder networked approach has helped to establish a culture of integrity at our institution, and make recommendations for others, wishing to do the same.
Academic Misconduct in Higher Education: Beyond Student Cheating
Authors: Christensen Hughes Julia , Eaton Sarah Elaine 
Published: March 2022

AbstractWhen people hear the term “academic misconduct”, student cheating often comes to mind. In this chapter we provide a broader perspective, presenting formal definitions of the terms academic integrity and academic misconduct, arguing that such concepts should apply to all members of the academy. Unfortunately, research conducted in the UK and the US suggests that faculty and administrators engage in misconduct and unethical practice, in research as well as other domains. Here we review policy changes in Canada’s approach to dealing with research misconduct, with the aim of strengthening “Canada’s research integrity system” (HAL in Innov Policy Econ, 2009, i). We also present public accounts of academic transgressions by Canadian faculty and administrators, with a primary focus on research misconduct. A query ofRetraction Watchfound 321 retractions involving academics working in Canadian higher education institutions during the years 2010–2020. Articles in the press are then used to further highlight incidents of academic fraud and plagiarism, as well as questionable practices in student supervision, hiring practices, international student recruitment, and inappropriate interpersonal relationships. We conclude by calling for a comprehensive study of academic misconduct by faculty and administrators at Canadian higher education institutions as well as an assessment of how well the changes to Canada’s policies on research misconduct are working, particularly with respect to public disclosure.
The tadpole conjecture at large complex-structure
Authors: Plauschinn Erik 
Published: March 2022

Abstract
The tadpole conjecture by Bena, Blåbäck, Graña and Lüst effectively states that for string-theory compactifications with a large number of complex-structure moduli, not all of these moduli can be stabilized by fluxes. In this note we study this conjecture in the large complex-structure regime using statistical data obtained by Demirtas, Long, McAllister and Stillman for the Kreuzer-Skarke list. We estimate a lower bound on the flux number in type IIB Calabi-Yau orientifold compactifications at large complex-structure and for large h2,1, and our results support the tadpole conjecture in this regime.
Scalar and fermion two-component SIMP dark matter with an accidental ℤ4 symmetry
Authors: Ho Shu-Yu , Ko Pyungwon , Lu Chih-Ting 
Published: March 2022

Abstract
In this paper, we construct for the first time a two-component strongly interacting massive particles (SIMP) dark matter (DM) model, where a complex scalar and a vector-like fermion play the role of the SIMP DM candidates. These two particles are stable due to an accidental ℤ4 symmetry after the breaking of a U(1)D gauge symmetry. By introducing one extra complex scalar as a mediator between the SIMP particles, this model can have 3 → 2 processes that determine the DM relic density. On the other hand, the SIMP DM particles can maintain kinetic equilibrium with the thermal bath until the DM freeze-out temperature via the U(1)D gauge couplings. Most importantly, we find an unavoidable two-loop induced 2 → 2 process tightly connecting to the 3 → 2 process that would redistribute the SIMP DM number densities after the chemical freeze-out of DM. Moreover, this redistribution would significantly modify the predictions of the self-interacting cross section of DM compared with other SIMP models. It is crucial to include the two-loop induced 2 → 2 annihilations to obtain the correct DM phenomenology.

Authors: Schieffer Lisa , Latzko Lukas , Ulmer Hanno , Schenz-Spisic Natalie , Lepperdinger Ulrike , Paulus Magdalena , Crismani Adriano G. 
Published: March 2022

Abstract
Purpose
To assess the validity, reliability, reproducibility, and objectivity of measurements on stone casts of patients with mixed dentitions compared to measurements on three-dimensional (3D) digital models derived from surface scans of the stone casts.

Methods
Pairs of stone casts of 30 young patients in their mixed dentition stage were included and processed into 3D digital models using an intraoral scanner (iTero Element 2; Align Technology, San Jose, CA, USA). Then an experienced and an inexperienced examiner independently performed measurements of five defined parameters, each in triplicate, both on the digital models with analysis software (OnyxCeph3™; Image Instruments, Chemnitz, Germany) and on the original casts with a vernier calliper. Paired t-tests were used for validity and interexaminer objectivity, Pearson correlation coefficients for intermethod reliability, and intraclass correlation coefficients (ICCs) for reproducibility testing.

Results
Significant (p < 0.05) intermethod differences were identified for four parameters, but only the differences for overbite and intermolar distance exceeded the threshold of clinical relevance (≥ 0.5 mm). Intermethod reliability was high and method error invariably lower for the digital measurements and for the experienced examiner. Both examiners achieved ICCs > 0.907 with both methods. Interexaminer variation involved significant differences for all parameters but one (intermolar distance) on the stone casts and for three parameters on the digital models.

Conclusion
Measurements performed on digital models of mixed dentitions can yield clinically acceptable outcomes with OnyxCeph3™ software. Both the digital and the analogue measurements were highly reproducible and reliable. Objectivity of the measurements could not be confirmed, as operator experience did make a difference.
A coupled multiphase Lagrangian-Eulerian fluid-dynamics framework for numerical simulation of Laser Metal Deposition process
Authors: Murer Mauro , Formica Giovanni , Milicchio Franco , Morganti Simone , Auricchio Ferdinando 
Published: March 2022

AbstractWe present a Computational Fluid Dynamics (CFD) framework for the numerical simulation of the Laser Metal Deposition (LMD) process in 3D printing. Such a framework, comprehensive of both numerical formulations and solvers, aims at providing a sufficiently exhaustive scenario of the process, where the carrier gas, modeled as an Eulerian incompressible fluid, transports metal powders, tracked as Lagrangian discrete particles, within the 3D printing chamber. On the basis of heat sources coming from the laser beam and the heated substrate, the particle model is developed to interact with the carrier gas also by heat transfer and to evolve in a melted phase according to a growth law of the particle liquid mass fraction. Enhanced numerical solvers, characterized by a modified Newton-Raphson scheme and a parallel algorithm for tracking particles, are employed to obtain both efficiency and accuracy of the numerical strategy. In the perspective of investigating optimal design of the whole LMD process, we propose a sensitivity analysis specifically addressed to assess the influence of inflow rates, laser beams intensity, and nozzle channel geometry. Such a numerical campaign is performed with an in-house code developed with the open source Finite Element library, and publicly available online.
Energy-based nonlinear dynamical modeling of dielectric elastomer transducer systems suspended by elastic structures
Authors: Masoud Abd Elkarim , Maas Jürgen 
Published: March 2022

AbstractThis paper presents the Hamilton principle approach to model, design and control mechatronic systems using dielectric elastomer transducers (DET) suspended with elastic structures. An overall dynamical modeling approach for dielectric elastomer-based actuators is presented, taking into account the dynamical effects, e.g., electrical input quantities, inertia, viscous effects, and the nonlinear behavior of DETs and elastic structures. Energy-based techniques are used to obtain a coherent modeling of the electrical and mechanical domains. Based on the variational principle and using the Rayleigh–Ritz method to approximate the field variable, a nonlinear state space model is derived considering various geometric deformations and boundary conditions. The presented approach leads to a set of ordinary differential equations that can be used for control and engineering applications. The proposed method is finally applied to a multilayer DET coupled with a nonlinear buckled beam structure and analyzed based on analytical considerations and numerical simulations.

Published: March 2022

AbstractThe Stanford Biodesign program was first introduced in Japan in 2015 at three national universities to develop medical technology innovation and its talent. This study aimed to (1) show the outcomes of leadership talent development, (2) indicate the educational results of the program, and (3) objectively analyze the ways in which the program executed in Japan, effectively promoted entrepreneurship orientation and the origination of new businesses. The latter is especially relevant as Japan has low entrepreneurial awareness and new business entry rates compared to the United States and Europe. Herein, fellows were subjected to questionnaires, interviews, and a survey based on academic papers, extant literature, and treatises issued by the Nihon Biodesign Gakkai (Academic Society of Japan Biodesign). Overall program performance showed notable results, despite indicating a need to improve business-related programs and team learning which is greatly influenced by Japanese culture. An externship program, planned and developed in Japan, was most inspiring and served to expose participants to role models. Comparing Japan Biodesign education elements to factors of general entrepreneurship promotion in Japan, sampled and organized from relevant White Papers, proved its educational effectiveness in entrepreneurship promotion from an objective viewpoint. Within the 4-year timeframe, the results indicated that leadership talent was indeed developed. Medical device innovation should progress through the stages of establishing new ventures, followed by contriving medical devices with novel, impactful value. This study revealed that Japan Biodesign education provides a platform for achieving these goals, despite the challenging Japanese new business environment.
A simple projection photolithography method for low-cost rapid prototyping of microfluidic chips
Authors: Ostmann Stefan , Kähler Christian J. 
Published: March 2022

AbstractPresented herein is a masking method for SU8 based soft lithography which utilizes a simple optical setup using transparencies printed with a commercial standard office printer. The relatively low printing quality of the printer is partly overcome by imaging of the mask with negative magnification that utilizes relatively cheap and easily available parts. The imaging quality as well as the quality of the resulting SU8 master is assessed by means of microscopic imaging.
Norwegian School Children’s Perceptions of the Child Protection Services
Authors: Vis Svein Arild , Berger Tonje , Lauritzen Camilla 
Published: March 2022

Abstract
Purpose
Schools can be an arena for age appropriate and objective information about the support families can get from the child protection services (CPS). There is reason to believe that many children have misconceptions about the CPS and are afraid to talk to the social workers who investigates if there is reason to be concerned about a child’s well-being. The aim of the study was to investigate the prevalence of misconceptions about child protection services (CPS) among school children in Norway.

Method
A questionnaire containing 10 statements that measure children’s misconceptions and attitudes about the CPS was developed and distributed to 215 children aged 11–15 years old (M = 12.2 years).

Results
The results showed that 10.7% of the sample have a misconception about children being removed from their homes by CPS and that 17% of the sample had a negative perception of the CPS in general.

Discussion
The child might wrongfully get the impression that it is at risk of being removed from the parents. Participation in assessment and planning may be challenging for a child under such conditions. Therefore, it is important that adults who work with children are aware that these misconceptions are quite common, also among youth.

Implications
The prevalence of misconceptions about CPS among children in the general population as well as those in contact with CPS indicate a need for age-appropriate information. If such misconceptions are prevented it might be easier for children to reach out for help if they or somebody they know, are subject to abuse or neglect.
Longitudinal Associations Between Parenting and Child Behaviour Problems and the Moderating Effect of Child Callous Unemotional Traits in Foster and Biological Families

Published: March 2022

AbstractThe goals of the current study were to examine (i) differences in parenting between foster and biological parents, (ii) the longitudinal associations with children’s internalising and externalising problems and iii) the potential moderation of these by children’s callous-unemotional traits (CU traits). Data from 86 foster children (M = 4.44 years, male = 48%) and 148 biological children (M = 3.69 years, male = 49%) with their families were analysed in a longitudinal study with three measurement times. Parenting behaviour did not significantly differ between the foster and biological family groups. Significant longitudinal cross-lagged effects were found for parental warmth and support and children’s externalising problems. CU traits moderated the relationship between warmth and support and externalising problems of children. Findings suggest that parenting behaviours and child psychopathology do influence each other over time reciprocally and to a similar extent in both groups. However, there was also evidence for greater temporal stability of psychopathological symptoms and reduced responsivity to parental warmth in children with higher CU traits.
Child Execution in Iran: Furthering Our Understanding of Child Execution as a Form of Structural Violence
Authors: Aghtaie Nadia , Staines Jo 
Published: March 2022

AbstractThis article explores how the concepts of strucutral violence and cultural violence can explain the institutionalization and normalization of violence in children’s lives in Iran, including the use of the death penalty, thereby providing a mechanism through which such violence can be challenged. The paper reflects on how an alternative to execution, the payment of blood money, diyah, mitigates but does not eradicate harms caused to child offenders convicted of Qesas offenses and how diyah is used by Iranian authorities to avoid fulfilling their legal obligations to children who offend. The article argues that eradicating child execution and the payment of blood money is dependent on challenging the structural violence that is embedded within Iran’s legal structures and it reflects on recent improvements in the legal system.
Delandtsheer–Doyen parameters for block-transitive point-imprimitive 2-designs
Authors: Amarra Carmen , Devillers Alice , Praeger Cheryl E. 
Published: March 2022

AbstractDelandtsheer and Doyen bounded, in terms of the block size, the number of points of a point-imprimitive, block-transitive 2-design. To do this they introduced two integer parameters m, n, now called Delandtsheer–Doyen parameters, linking the block size with the parameters of an associated imprimitivity system on points. We show that the Delandtsheer–Doyen parameters provide upper bounds on the permutation ranks of the groups induced on the imprimitivity system and on a class of the system. We explore extreme cases where these bounds are attained, give a new construction for a family of designs achieving these bounds, and pose several open questions concerning the Delandtsheer–Doyen parameters.
Relationships between computational thinking and the quality of computer programs
Authors: Boom Kay-Dennis , Bower Matt , Siemon Jens , Arguel Amaël 
Published: March 2022

AbstractComputational thinking – the ability to reformulate and solve problems in ways that can be undertaken by computers – has been heralded as a foundational capability for the 21st Century. However, there are potentially different ways to conceptualise and measure computational thinking, for instance, as generalized problem solving capabilities or as applied practice during computer programming tasks, and there is little evidence to substantiate whether higher computational thinking capabilities using either of these measures result in better quality computer programs. This study examines the relationship between different forms of computational thinking and two different measures of programming quality for a group of 37 pairs of pre-service teachers. General computational thinking capabilities were measured using Bebras tests, while applied computational thinking processes were measured using a Computational Thinking Behavioural Scheme. The quality of computer programs was measured using a qualitative rubric, and programs were also assessed using the Dr Scratch auto-grading platform. The Test of Nonverbal Intelligence (3rd edition, TONI-3) was used to test for confounding effects. While significant correlations between both measures of computational thinking and program quality were detected, regression analysis revealed that only applied computational thinking processes significantly predicted program quality (general computational thinking capability and non-verbal intelligence were not significant predictors). The results highlight the importance of students developing applied computational thinking procedural capabilities more than generalized computational thinking capabilities in order to improve the quality of their computer programs.
Can you be Mindful? The Effectiveness of Mindfulness-Driven Interventions in Enhancing the Digital Resilience to Fake News on COVID-19

Published: March 2022

AbstractThis study explores the factors that influence the dissemination process of and public susceptibility to fake news amidst COVID-19. By adopting a qualitative approach that draws on 21 interviews with social media users from the standpoint of source credibility and construal level theories, our findings highlight motives of news sharers, platform features, and source credibility/relatedness as major factors influencing the dissemination of and public susceptibility to fake news. The paper further argues that public susceptibility to fake news can be mitigated by building an integrated approach that combines a tripartite strategy from an individual, institutional and platform level. For example, educating the public on digital resilience and enhancing awareness around source credibility can help individuals and institutions reflect on news authenticity and report fake news where possible. This study contributes to fake news literature by integrating concepts from information management, consumer behaviour, influencer marketing and mindfulness to propose a model to help authorities identify and understand the key factors that influence susceptibility to fake news during a public crisis such as COVID-19.

Authors: Holmberg Bergman T. , Renhorn E. , Berg B. , Lappalainen P. , Ghaderi A. , Hirvikoski T. 
Published: March 2022

AbstractParents of children with autism spectrum disorder and other disabilities report high levels of distress, but systematically evaluated interventions are few. This study aimed to evaluate the feasibility of a novel, manualized Acceptance and Commitment Therapy group intervention (Navigator ACT) in a sample of 94 parents of children with disabilities. Feasibility was measured by treatment completion, credibility, and satisfaction, and preliminary outcomes by using self-rating scales administered at the baseline, post-intervention, and follow-up. The results imply the intervention is feasible in the context of Swedish outpatient habilitation services. A preliminary analysis of the outcome measures suggests that parents experienced significant improvements in well-being. The results indicate that the treatment is feasible and should be evaluated in a randomized controlled trial.

Published: March 2022

Abstract47Sc can be produced from different three neutron induced nuclear reactions as 47Ti(n,p)47Sc, 50V(n,α)47Sc and 46Ca(n,γ)47Ca, 47Ca(β−)47Sc using the Egyptian Second Research Reactor. The measured neutron cross-sections (σ) are 62.12 ± 1.93, 4.51 ± 1.27 and 69.36 ± 2.01 mb from the natural targets of TiO2, V2O3 and CaO respectively. The carrier-free 47Sc from 47Ti(n,p), was purified using a composite of Alginate–Carboxymethyl cellulose/di-2-ethylhexyl phosphoric acid. The radiochemical separation of 47Sc with a recovery yield of 90 ± 1.2% was obtained. The eluted 47Sc passed quality control tests (chemical, radionuclide, and radiochemical purities) and was found to be suitable for nuclear medicine applications.
