Employee perspectives on value realization from data within data-driven business models
Authors: Förster Matthias , Bansemir Bastian , Roth Angela 
Published: March 2022

AbstractFirms are innovating data-driven business models (DDBMs) to realize value from data. Yet, making DDBMs work is challenging, and DDBMs often fall short of expected value realization. One reason for this shortfall is that firms do not know how employees, who decisively influence a DDBM’s value realization, view this complex and multi-facetted topic. We think it is necessary to understand the employees’ perspectives, the dimensions that build these perspectives and the characteristics employees are particularly interested in regarding value realization from data. We address this research gap by applying the Q-methodology to examine the perspectives among 70 employees across twelve DDBMs at a German automotive manufacturer. This yields eight perspectives, e.g., data advocacy, data caution or data practical. By exploring these perspectives, we provide a first groundwork on how employees view and appraise value realization from data which adds to the strive for mastering value realization from data within DDBMs.
Uniqueness of martingale solutions for the stochastic nonlinear Schrödinger equation on 3d compact manifolds
Authors: Brzeźniak Zdzisław , Hornung Fabian , Weis Lutz 
Published: March 2022

AbstractWe prove the pathwise uniqueness of solutions of the nonlinear Schrödinger equation with conservative multiplicative noise on compact 3D manifolds. In particular, we generalize the result by Burq, Gérard and Tzvetkov, [7], to the stochastic setting. The proof is based on the deterministic and new stochastic spectrally localized Strichartz estimates and the Littlewood-Paley decomposition.
A Case for Openness – Book Publishing and the Role of Amazon
Authors: Kreutzmann-Gallasch Antje , Schroff Simone 
Published: March 2022

AbstractThe presence of Amazon is ubiquitous, especially in the online bookstore and e-book market. The introduction of the “Kindle” further cemented Amazon’s dominant position and business model in the market, having negative implications for authors, publishers and consumers. Publishers have less control over setting the price to have access to Amazon’s customer base. This will affect the authors’ remuneration and attribution. On the other hand, Kindle users are locked-in consumers, limited to Amazon’s e-book offering. This not only affects consumer choice but also reinforces Amazon’s market power due to the significant network effects. The European Commission attempted to increase competition in the e-book market by banning most-favourite-nation clauses, but this has seemingly failed. This article advocates for enforcing the Kindle’s interoperability with the e-book formats of other e-book providers. The proposed approach is beneficial for publishers as well as consumers. It safeguards copyright aims while alleviating the contractual constraints imposed by Amazon. Furthermore, consumers would benefit from broader flexibility when using their Kindle, allowing them to store and read e-books from the provider of their choice.

Abstract
Purpose
Girls affected with Turner syndrome (TS) present with low bone mineral density (BMD) and osteopenia/osteoporosis. Thus, they have an increased risk to develop fractures compared to normal population. The aim of this study was to deepen the pathophysiology of skeletal fragility in TS subjects by evaluating the serum levels of Dickkopf-1 (DKK-1) and sclerostin, main regulators of bone mass, as well as the percentage of circulating osteoblast precursors (OCPs).

Methods
Thirty-four TS girls and 24 controls were recruited. All subjects underwent anthropometric measures (height, weight, body mass index-BMI). A peripheral venous blood sample was collected to determine serum levels of active intact parathyroid hormone (PTH), 25-OH vitamin D, calcium, phosphorus, bone alkaline phosphatase (bALP), osteocalcin, sclerostin, DKK-1, RANKL and OPG. OCPs were detected by flow cytometry. In TS subjects bone mineralization was measured at lumbar spine by dual energy X-ray absorptiometry (DXA).

Results
bALP, 25-OH Vitamin D, and osteocalcin levels were significant lower in TS subjects than in the controls. Statistically significant higher levels of sclerostin, DKK-1 and RANKL were measured in patients compared with the controls. The percentage of OCPs did not show significant differences between patients and controls. Sclerostin and DKK-1 levels were related with anthropometric parameters, bone metabolism markers, HRT, rhGH therapy, RANKL and lumbar BMAD-Z-score.

Conclusion
TS patients showed higher levels of sclerostin and DKK-1 than controls which can be related to HRT, and to reduced bone formation markers as well as the increased bone resorption activity.
Top R&D investors, structural change and the R&D growth performance of young and old firms
Authors: Moncada-Paternò-Castello Pietro 
Published: March 2022

AbstractThis paper investigates the structural change of the major economies through the lens of the leading global corporate R&D investors. Moreover, we explore the relationship between R&D intensity, capital intensity and profitability and R&D investment growth for young and old firms. Contrary to common understanding, our results show that in the EU the R&D distribution between sectors has changed – similar to the USA; however, the USA has experienced a very strong shift towards ICT-related sectors, which makes its change more visible. Both the EU and the USA have experienced a slower pace of structural change than emerging economies. Our results also indicate that capital and R&D intensity may have a complementary effect on long-term R&D performance, which can vary according to a firm’s age. The specific nature of the sample allows us to link our results to the Schumpeterian waves of innovation and the changes of techno-economic paradigms rather than alternative interpretation of management literature. Policy implications are discussed accordingly.
An Efficient Solution to Ray Tracing Problems in Multimedia Photogrammetry for Flat Refractive Interfaces
Authors: Rofallski Robin , Luhmann Thomas 
Published: March 2022

AbstractUnderstanding and considering refraction effects are important parts of the demanding task of multimedia photogrammetry, especially with planar interfaces, so-called ”flat ports”. Yet, it remains challenging to determine reliable calibration results that are both quickly acquired and physically interpretable. In this contribution, a novel object-based optimization algorithm, relying on ray tracing methods, is introduced. It enables calibrating physical parameters of all involved refractive properties with reduced computational effort, compared to other standard algorithms in ray tracing. We show that this solution produces equally accurate results as other ray tracing approaches while improving processing speed by a factor of approximately ten and providing a statistical metric in object space. Furthermore, we show in a laboratory investigation that explicit calibration of refractive properties is crucial even with orthogonally aligned bundle-invariant interfaces for highest accuracy, as accuracy in object space is decreased by about 10% with implicit calibration. With deviation from orthogonality by about ten degrees this decreases even further to almost no useful results and accuracy loss of more than 50% compared to explicit calibration results.

Published: March 2022

AbstractSince none of the existing systematic reviews of the literature related to smart cities have focused on smart cities applications using context-aware features, this study aims to provide a comprehensive view of (1) the characteristics of context-aware applications supported by smart cities’ infrastructures, (2) the characteristics of the context-aware technologies being used, and (3) the maturity level of the identified applications. An electronic search was conducted on Scopus, Web of Science, and IEEE Xplore databases, combining relevant keywords. After the studies’ selection, 27 studies were included. The results show the interest in using context-aware features to develop smart cities’ applications targeting public health, tourism experience, urban mobility, active citizenship, shopping experience, management of urban infrastructures, public alerts, recommenders, and smart environments. Moreover, the applications reported by the included studies do not allow the execution of actions without the explicit consent of the users, and they integrate personal sensors, sensors deployed in the city and crowdsourcing mechanisms to acquire primary context attributes (i.e., location, activity, and environment) and secondary context attributes (i.e., speed, physical activity, points of interest, stress, and tourists’ emotions). In addition, the included studies present scarce details about context reasoning, data privacy, integrity, and confidentiality, data aggregation and accuracy, and data interoperability. Finally, the results also indicate low maturity level of the developed applications, which is evidenced by the lack of user-centred evaluations, as well as by the difficulty in integrating important technologies being developed for smart cities.
Government Formation and the Radical Right: A Swedish Exception?
Authors: Backlund Anders 
Published: March 2022

AbstractThis article tests the claim that government cooperation between mainstream parties and radical right parties can be explained by coalition theory. It does so by analysing three Swedish cases of coalition formation where the radical right Sweden Democrats (SD) have remained excluded despite holding a pivotal position in the parliament. It argues that, with the right analytical tools, this exclusion can be explained by coalition theory: cooperation with the SD has been unattractive in terms of policy, and unnecessary because the mainstream parties have been able to form viable minority governments. This argument requires three things: first, that we consider the two-dimensional nature of Swedish politics; second, that we shift the focus from majority government to viable government; and third, that we acknowledge strategic time horizons that extend well into the future. The findings contribute to our understanding of coalition formation and of how mainstream parties respond strategically to the radical right.

Abstract

Objective:
To assess the validity of Antigen rapid diagnostic tests (Ag-RDT) for SARS-CoV-2 as decision support tool in various hospital-based clinical settings.

Design:
Retrospective cohort study among symptomatic and asymptomatic patients and Healthcare workers (HCW).

Setting:
A large tertiary teaching medical center serving as a major COVID-19 hospitalizing facility.

Participants and Methods:
Ag-RDTs’ performance was assessed in three clinical settings: 1. Symptomatic patients and HCW presenting at the Emergency Departments 2. Asymptomatic patients screened upon hospitalization 3. HCW of all sectors tested at the HCW clinic following exposure.

Results:
We obtained 5172 samples from 4595 individuals, who had both Ag-RDT and quantitative real-time PCR (qRT-PCR) results available. Of these, 485 samples were positive by qRT-PCR. The positive percent agreement (PPA) of Ag-RDT was greater for lower cycle threshold (Ct) values, reaching 93% in cases where Ct-value was <25 and 85% where Ct-value was <30. PPA was similar between symptomatic and asymptomatic individuals. We observed a significant correlation between Ct-value and time from infection onset (p<0.001).

Conclusions:
Ag-RDT are highly sensitive to the infectious stage of COVID-19 manifested by either high viral load (lower Ct) or proximity to infection, whether patient is symptomatic or asymptomatic. Thus, this simple-to-use and inexpensive detection method can be used as a decision support tool in various in-hospital clinical settings, assisting patient flow and maintaining sufficient hospital staffing.

AbstractSevere acute respiratory coronavirus virus 2 (SARS-CoV-2) transmissions among healthcare workers and hospitalized patients are challenging to confirm. Investigation of infected persons often reveals multiple potential risk factors for viral acquisition. We combined exposure investigation with genomic analysis confirming 2 hospital-based clusters. Prolonged close contact with unmasked, unrecognized infectious, individuals was a common risk.
New trematode species Lecithostaphylus halongi n. sp. (Zoogonidae, Microphalloidea) and Gymnotergestia strongyluri n. sp. (Fellodistomidae, Gymnophalloidea) from beloniform fishes in Vietnam

Abstract
In this study we described two new trematode species, Lecithostaphylus halongi n. sp. (Zoogonidae, Lecithostaphylinae) and Gymnotergestia strongyluri n. sp. (Fellodistomidae, Tergestiinae), on the basis of morphological and molecular data. Adult worms of these two species were collected from, respectively, Hemiramphus spp. (Hemiramphidae) and Strongylura strongylura (Belonidae) caught in the coastal waters of Vietnam. Adult worms of L. halongi n. sp. are morphologically close to Lecithostaphylus gibsoni Cribb, Bray & Barker, 1992 ex Abudefduf whitleyi from Heron Island and Lecithostaphylus depauperati Yamaguti, 1970 ex Hemiramphus depauperatus from Hawaii, but differ from these species in having a larger cirrus sac and a different arrangement of vitelline fields. They also differ from Lecithostaphylus brayi Cabañas-Granillo, Solórzano-García, Mendoza-Garfias & Pérez-Ponce de León, 2020 in the 28S ribosomal DNA (rDNA) sequence data at the interspecific level. Adult worms of G. strongyluri n. sp. ex S. strongylura are morphologically similar to Gymnotergestia chaetodipteri, the only previously known species of this genus, described from Chaetodipterus faber in Jamaica. The new species differs from G. chaetodipteri in body shape, testicular arrangement and the size of the pharynx and eggs. The 28S rDNA-based phylogenetic analysis indicates that G. strongyluri n. sp. is closely related to Tergestia spp., rendering Tergestia paraphyletic. Genetic divergence values between G. strongyluri n. sp. and Tergestia spp. are similar to those among species in the genera Tergestia, Steringophorus and Proctoeces. Our molecular results indicate that G. strongyluri n. sp. and Tergestia spp. may belong the same genus, but additional molecular data are needed for the final conclusion.

Published: March 2022

AbstractWhile debate on how best to pay for social care in England continues, information about public attitudes on this issue is limited. We asked representative samples of the public whether care costs for older people should be met by the state, met by the service user or shared between state and user. We used an online survey of people aged 18–75 (n = 3,000) and interview survey of people aged 65 and over (n = 466). Respondents were given four vignettes (two home care, two residential care) and asked who should pay at different levels of user resources; and how much users should contribute when costs were shared. Fewer than one-fifth of the online sample and one-quarter of the interview sample considered that the state should meet the full costs whatever users’ resources; considerably lower proportions believed that users should meet the full costs in all cases. Two-thirds of the online sample and half the interview sample thought costs should be shared. The proportion of costs that users should contribute was relatively low (20–50 per cent, varying by user resources). The study illustrates that public views elicited through vignettes can provide evidence to inform policy on social care funding.

Abstract
Seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgG antibodies, using dried blood spots, was determined in October–November 2020, among residents and staff randomly selected from 20 nursing homes (NH) geographically distributed in Flanders, Belgium. Sociodemographic and medical data [including coronavirus disease 2019 (COVID-19) symptoms and results of RT-PCR tests] were retrieved using questionnaires. The overall seroprevalence was 17.1% [95% confidence interval (CI) 14.9–19.5], with 18.9% (95% CI 15.9–22.2) of the residents and 14.9% (95% CI 11.9–18.4) of the staff having antibodies, which was higher than the seroprevalence in blood donors. The seroprevalence in the 20 NH varied between 0.0% and 45.0%. Fourteen per cent of the staff with antibodies, reported no typical COVID-19 symptoms, while in residents, 51.0% of those with antibodies had no symptoms. The generalised mixed effect model showed a positive association between COVID-19 symptoms and positive serology, but this relation was weaker in residents compared to staff. This study shows that NH are more affected by SARS-CoV-2 than the general population. The large variation between NH, suggests that some risk factors for the spread among residents and staff may be related to the NH. Further, the results suggest that infected people, without the typical COVID-19 symptoms, might play a role in outbreaks.
Timing of pulmonary valve replacement: can we use the same volumetric thresholds in repaired tetralogy of Fallot and pulmonary stenosis?

Published: March 2022

AbstractThe timing of pulmonary valve replacement in patients with pulmonary regurgitation following treatment of pulmonary stenosis is undefined. Although cardiac magnetic resonance-based right ventricular volumes in tetralogy of Fallot patients have been used as a guide in pulmonary stenosis patients, anatomic differences between tetralogy of Fallot and pulmonary stenosis patients complicate their application to pulmonary stenosis patients and could result in late referral for pulmonary valve replacement. We sought to determine if pulmonary stenosis patients referred for pulmonary valve replacement were at greater risk for morbidity or need for tricuspid valve intervention at the time of pulmonary valve replacement. A retrospective cohort study was performed on all adult patients with a diagnosis of pulmonary stenosis or tetralogy of Fallot followed at our centre. Clinical and imaging-based exposures were collected. Pre-specified endpoints included need for concomitant tricuspid valve repair or replacement and pre- and post-pulmonary valve replacement cardiac magnetic resonance-based volumetric measurements. Between 1/1999 and 1/2020, 235 patients underwent pulmonary valve replacement for pulmonary regurgitation (52 with pulmonary stenosis, 183 with tetralogy of Fallot). Pulmonary stenosis patients were more likely to have at least moderate tricuspid regurgitation (p = 0.010), undergo concomitant tricuspid valve intervention (p = 0.003), and require tricuspid valve repair or replacement secondary to annular dilation (p = 0.027) compared to tetralogy of Fallot patients. There was no difference in pre-pulmonary valve replacement right ventricular size between pulmonary stenosis and tetralogy of Fallot patients. These findings suggest that referral for pulmonary valve replacement may be occurring later in the disease course for pulmonary stenosis patients.
Supporting Volunteer Firefighter Well-Being: Lessons from the Australian “Black Summer” Bushfires

Published: March 2022

AbstractIntroduction:The 2019-2020 “Black Summer” bushfires in Australia focused the attention of the nation on the critical role that volunteer firefighters play in the response to such a disaster, spurring a national conversation about how to best support those on the frontline. The objective of this research was to explore the impact of the Black Summer bushfires on volunteer firefighter well-being and to investigate how to deliver effective well-being support.Methods:An explorative qualitative design underpinned by a phenomenological approach was applied. Participant recruitment followed a multi-modal sampling strategy and data were collected through semi-structured, in-depth interviews.Results:Qualitative data were collected from 58 participants aged from 23 to 61-years-of-age (average age of 46 years). All self-reported as volunteer firefighters who had responded to the Black Summer bushfires in Australia. Just over 80% of participants were male and the majority lived in the Australian states of New South Wales (65%) and Victoria (32%). All participants reported impact on their well-being, resulting from cumulative trauma exposure, responding to fires in local communities, intense work demands, minimal intervals between deployments, and disruption to primary employment. In regard to supporting well-being, four key themes emerged from data analysis: (1) Well-being support needs to be both proactive and reactive and empower local leaders to “reach in” while encouraging responders to “reach out;” (2) Employee Assistance Programs (EAPs) should not be the only well-being support option available; (3) The sharing of lived experience is important; and (4) Support programs need to address self-stigmatization.Conclusion:Participants in this research identified that effective well-being support needs to be both proactive and reactive and holistic in approach.
