Creating hospitable service systems for refugees during a pandemic: leveraging resources for service inclusion

Purpose: The overarching goal of this paper is to increase awareness among researchers and practitioners that refugees are disproportionally impacted by COVID-19, which increases their suffering. Second, it extends a recently introduced transformative refugee service experience framework by integrating and conceptualizing refugees' resource and service inclusion during a pandemic. Third, it explores lessons learned and implications from the COVID-19 pandemic for the future of service research and practice. Design/methodology/approach: This study synthesizes approaches on refugees, resources and transformative service research to develop an extended framework for addressing one of society's pressing issues during and after pandemics. Findings: Recognizing refugees as providing resources rather than just needing or depleting resources can enable more inclusion. It facilitates refugees' integration into society by drawing on their skills and knowledge. This requires hospitable refugee service systems that enable service inclusion and opportunities for refugee resource integration. Research limitations/implications: This article focuses on one vulnerable group in society. However, the extended framework presented warrants broader application to other contexts, such as subsistence marketplaces. Practical implications: Managers of service businesses and public policymakers should create more inclusive and hospitable service systems for refugees. This may result in redesigning services, changing consumer behavior and reformulating public policy. Social implications: Better inclusion and integration of refugees and their resources should increase their individual well-being, reduce social issues in society, increase overall societal well-being and productivity. Originality/value: This article presents a novel extended framework for service scholars and service providers to increase resource and service inclusion of refugees in a disaster context

Research Methodologies for Participants Experiencing Vulnerability: A Transformative Service Research Perspective

Understanding vulnerable consumers when conducting Transformative Service Research (TSR) is essential but these consumers and their contexts are often complex and difficult to research. Despite a movement towards TSR research methodologies suitable for studying vulnerable participants and their contexts, a comprehensive framework that can guide service researchers is lacking. The purpose of this paper is to investigate appropriate methods, procedures, and protocols that permit researching a wide range of vulnerable groups and exposures to vulnerable situations in TSR. This is undertaken via a review of the literature and the authors’ reflections of their experience researching vulnerability in various configurations (e.g., disasters, refugees, healthcare, disability, and older people). Through an iterative process of personal case reflections and group discussions blended with extant literature, patterns and insights regarding appropriate research protocols, techniques, processes, and sampling are identified. These insights contribute to the development of a comprehensive TSR framework in five research method areas including 1) consideration of the context, researcher, support persons and participants, 2) recruitment considerations relating to sampling, 3) recruitment considerations in terms of ethics and set-up, 4) data collection considerations relating to research protocol and set-up, and 5) data collection considerations. The framework can guide both academics and practitioners to enhance research outcomes for both participants and researchers

Towards co-created food wellbeing: Culinary consumption, braggart word-of-mouth, and the role of participative co-design, service provider support, and C2C interactions

Purpose: This study aims to investigate whether the antecedents of co-creation influence braggart word-of-mouth (WoM) in a participative leisure context, theorising the concept of co-created food well-being and highlighting implications for interactive experience co-design. Design/methodology/approach: A sequential mixed-method approach was used to test a theoretical model; 25 in-depth interviews with cooking class participants were conducted, followed by a post-experience survey (n = 575). Findings: Qualitative results suggest braggart WoM is rooted in active consumer participation in co-designing leisure experiences. The structural model confirms that participation in value co-creating activities (i.e. co-design, customer-to-customer (C2C) interaction), alongside perceived support from service providers, increases consumer perceptions of co-creation and stimulates braggart WoM. Degree of co-creation and support from peers mediate some relationships. Research limitations/implications: Limited by cross-sectional data from one experiential consumption format, the results nevertheless demonstrate the role of active participation in co-design and C2C interactions during value co-creation. This implies that co-created and co-designed leisure experiences can intensify post-consumption behaviours and potentially enhance food well-being. Practical implications: The results highlight that integrating customer participation into service design, while also developing opportunities for peer support on-site, can stimulate braggart WoM. Originality/value: Extends burgeoning literature on co-creation and co-design in leisure services. By encouraging active customer participation while providing support and facilitating C2C interactions, service providers can enhance value co-creation, influencing customer experiences and food well-being. Accordingly, the concept of co-created food well-being is introduced

Test Case Prioritization for Acceptance Testing of Cyber Physical Systems: A Multi-Objective Search-Based Approach

Acceptance testing validates that a system meets its requirements and determines whether it can be sufficiently trusted and put into operation. For cyber physical systems (CPS), acceptance testing is a hardware-in-the-loop process conducted in a (near-)operational environment. Acceptance testing of a CPS often necessitates that the test cases be prioritized, as there are usually too many scenarios to consider given time constraints. CPS acceptance testing is further complicated by the uncertainty in the environment and the impact of testing on hardware. We propose an automated test case prioritization approach for CPS acceptance testing, accounting for time budget constraints, uncertainty, and hardware damage risks. Our approach is based on multi-objective search, combined with a test case minimization algorithm that eliminates redundant operations from an ordered sequence of test cases. We evaluate our approach on a representative case study from the satellite domain. The results indicate that, compared to test cases that are prioritized manually by satellite engineers, our automated approach more than doubles the number of test cases that fit into a given time frame, while reducing to less than one third the number of operations that entail the risk of damage to key hardware components

Dogs as carriers of virulent and resistant genotypes of Clostridioides difficile

Abstract While previous research on zoonotic transmission of community-acquired Clostridioides difficile infection (CA-CDI) focused on food-producing animals, the present study aimed to investigate whether dogs are carriers of resistant and/or virulent C. difficile strains. Rectal swabs were collected from 323 dogs and 38 C. difficile isolates (11.8%) were obtained. Isolates were characterized by antimicrobial susceptibility testing, whole-genome sequencing (WGS) and a DNA hybridization assay. Multilocus sequence typing (MLST), core genome MLST (cgMLST) and screening for virulence and antimicrobial resistance genes were performed based on WGS. Minimum inhibitory concentrations for erythromycin, clindamycin, tetracycline, vancomycin and metronidazole were determined by E-test. Out of 38 C. difficile isolates, 28 (73.7%) carried genes for toxins. The majority of isolates belonged to MLST sequence types (STs) of clade I and one to clade V. Several isolates belonged to STs previously associated with human CA-CDI. However, cgMLST showed low genetic relatedness between the isolates of this study and C. difficile strains isolated from humans in Austria for which genome sequences were publicly available. Four isolates (10.5%) displayed resistance to three of the tested antimicrobial agents. Isolates exhibited resistance to erythromycin, clindamycin, tetracycline and metronidazole. These phenotypic resistances were supported by the presence of the resistance genes erm(B), cfr(C) and tet(M). All isolates were susceptible to vancomycin. Our results indicate that dogs may carry virulent and antimicrobial-resistant C. difficile strains.1 Introduction 2 Methods 2.1 Sampling and ethics 2.2 Isolation and identification of Clostridioides difficile 2.3 Antimicrobial susceptibility testing 2.4 Whole-genome sequencing and comparative genomic analysis 2.5 Statistical analysis 3 Results 3.1 Prevalence of Clostridioides difficile and risk factors for shedding 3.2 Antimicrobial susceptibility testing and detection of antimicrobial resistance determinants 3.3 Genomic characterization of canine Clostridioides difficile 3.4 Genome annotation and comparison 4 Discussio

An integrative transformative service framework to improve engagement in a social service ecosystem: The case of He Waka Tapu

Purpose: This study aims to attempt to understand the engagement between an indigenous social service provider and marginalised clients deemed “hard-to-reach” to gain an insight into how to improve the client’s engagement and well-being through transformative value co-creation. Design/methodology/approach: The exploratory study’s findings draw on primary data employing a qualitative research approach through document analysis and in-depth interviews with clients, social workers and stakeholders of the focal social service provider in New Zealand. Findings: The findings indicate that there are inhibitors and enablers of value or well-being co-creation. The lack of client resources and a mismatch between client and social worker are primary barriers. Other actors as well as cultural practices are identified as enablers of well-being improvement. Research limitations/implications: This research reports on a single social service provider and its clients. These findings may not be readily transferrable to other contexts. Practical implications: Findings indicate that social service providers require a heightened awareness of the inhibitors and enablers of social service co-creation. Social implications: Both the integrative framework and the findings provide a sound critique of the prevailing policy discourse surrounding the stigmatisation of members of society deemed “hard-to-reach” and the usefulness of such an approach when aiming at resolving social issues. Originality/value: This is the first exploratory study that reports on the engagement between a social service provider and its clients in a dedicated Maori (indigenous) context by employing an integrative research approach combining transformative service research, activity theory and engagement theory

Autocalibration with the Minimum Number of Cameras with Known Pixel Shape

In 3D reconstruction, the recovery of the calibration parameters of the cameras is paramount since it provides metric information about the observed scene, e.g., measures of angles and ratios of distances. Autocalibration enables the estimation of the camera parameters without using a calibration device, but by enforcing simple constraints on the camera parameters. In the absence of information about the internal camera parameters such as the focal length and the principal point, the knowledge of the camera pixel shape is usually the only available constraint. Given a projective reconstruction of a rigid scene, we address the problem of the autocalibration of a minimal set of cameras with known pixel shape and otherwise arbitrarily varying intrinsic and extrinsic parameters. We propose an algorithm that only requires 5 cameras (the theoretical minimum), thus halving the number of cameras required by previous algorithms based on the same constraint. To this purpose, we introduce as our basic geometric tool the six-line conic variety (SLCV), consisting in the set of planes intersecting six given lines of 3D space in points of a conic. We show that the set of solutions of the Euclidean upgrading problem for three cameras with known pixel shape can be parameterized in a computationally efficient way. This parameterization is then used to solve autocalibration from five or more cameras, reducing the three-dimensional search space to a two-dimensional one. We provide experiments with real images showing the good performance of the technique.Comment: 19 pages, 14 figures, 7 tables, J. Math. Imaging Vi

Dynamics of Wellbeing Co-Creation: A Psychological Ownership Perspective

Purpose: People are responsible for their wellbeing, yet whether they take ownership of their own or even others' wellbeing might vary from actor to actor. Such psychological ownership (PO) influences the dynamics of how wellbeing is co-created, particularly amongst actors, and ultimately determines actors' subjective wellbeing. The paper's research objective pertains to explicating the concept of the co-creation of wellbeing and conceptualizing the dynamics inherent to the co-creation of wellbeing with consideration of the influences of all involved actors from a PO perspective. Design/methodology/approach: To provide a new conceptualization and framework for the dynamics of wellbeing co-creation, this research synthesizes wellbeing, PO and value co-creation literature. Four healthcare cases serve to illustrate the effects of engaged actors' PO on the co-creation of wellbeing. Findings: The derived conceptual framework of dynamic co-creation of wellbeing suggests four main propositions: (1) the focal actor's wellbeing state is the intangible target of the focal actor's and other engaged actors' PO, transformed throughout the process of wellbeing co-creation, (2) PO over the focal actor's wellbeing state is subject to the three interrelated routes of exercising control, investing in the target, and intimately knowing the target, which determine the instigation of wellbeing co-creation, (3) the level of PO over the focal actor's wellbeing state can vary, influence and be influenced by the extent of wellbeing co-creation, (4) the co-creation of wellbeing, evoked by PO, is founded on resource integration, which influences the resources–challenges equilibrium of focal actor and of all other engaged actors, affecting individual subjective wellbeing. Originality/value: This article provides a novel conceptual framework that can shed new light on the co-creation of wellbeing in service research. Through the introduction of PO the transformation of lives and wellbeing can be better understood
