Abstract
Aim
Asians are the second largest and fastest growing non-European population in New Zealand but are under-researched in terms of their COVID-19 pandemic response. The paper aims to illustrates Asians’ risk perceptions and knowledge of COVID-19, and self-protection practices to avoid infection and prevent community transmission.

Subject and methods
An online survey was used to collect data and received 402 valid responses. Data analyses included: 1) a descriptive analysis by using Chi-square tests and a Kruskal-Wallis rank sum tests to explore associations between responses and the four demographic variables (i.e. age, gender, country of origin/ethnicity, and region); and 2) a correlation analysis between different survey objectives.

Results
The descriptive analysis of the survey found that while ethnicity (within the Asian category) was the most influential variable that resulted in varying responses to many questions, gender and age were other two important variables in influencing the answering patterns. The correlation analysis found a positive correlation between the perceived ‘dangerousness’ of COVID-19 and respondents’ overall compliance behaviour to New Zealand authorities’ recommendations to prevent spread of COVID-19.

Conclusion
The majority of the respondents provided correct answers to the questions about the vulnerable populations, symptoms, asymptomatic transmission and potential sequelae of COVID-19; however, their understanding of the availability of a cure for, and the incubation period of COVID-19 was not consistent with the official information. The research also found that the higher perceived dangerousness of COVID-19, the better compliance to self-protection practices among the surveyed population.
Websites’ data: a new asset for enhancing credit risk modeling
Authors: Crosato Lisa , Domenech Josep , Liberati Caterina 
Published: May 2023

AbstractRecent literature shows an increasing interest in considering alternative sources of information for predicting Small and Medium Enterprises default. The usage of accounting indicators does not allow to completely overcome the information opacity that is one of the main barriers preventing these firms from accessing to credit. This complicates matters both for private lenders and for public institutions supporting policies. In this paper we propose corporate websites as an additional source of information, ready to be exploited in real-time. We also explore the joint use of online and offline data for enhancing correct prediction of default through a Kernel Discriminant Analysis, keeping the Logistic Regression and the Random Forests as benchmark. The obtained results shed light on the potentiality of these new data when accounting indicators lead to a wrong prediction.

AbstractA priori Direct Numerical Simulation (DNS) assessment of mean reaction rate closures for reaction progress variable in the context of Reynolds Averaged Navier–Stokes (RANS) simulations has been conducted for MILD combustion of homogeneous (i.e., constant equivalence ratio), methane-air mixtures. The reaction rate predictions according to statistical (e.g., presumed probability density function), phenomenological (e.g., eddy-break up (EBU), eddy dissipation concept (EDC) and the scalar dissipation rate (SDR) based approaches), and flame surface description (e.g., Flame Surface Density) based closures are compared. The performance of the various reaction rate closures has been assessed by comparing the models’ predictions to the corresponding quantities extracted from DNS data. It has been found that the usual presumed probability density function (PDF) approach using the beta-function predicts the PDF of the reaction progress variable in homogenous mixture MILD combustion throughout the flame brush for all cases considered here provided that the scalar variance is accurately predicted. The accurate estimation of scalar variance requires the solution of a modelled transport equation, which depends on the closure of Favre-averaged SDR. A linear relaxation based algebraic closure for the Favre-averaged SDR has been found to capture the behaviour of the Favre-averaged SDR in the current homogenous mixture MILD combustion setup. It has been found that the EBU, SDR and FSD-based mean reaction rate closures do not adequately predict the mean reaction rate of the reaction progress variable for the parameter range considered here. However, a variant of the EDC closure, with model coefficients expressed as functions of micro-scale Damköhler and turbulent Reynolds numbers, has been found to be more successful in predicting the mean reaction rate of reaction progress variable compared to other modelling methodologies for the range of turbulence intensities and dilution levels considered here.

AbstractProlonged high-intensity endurance exercise has been reported to have adverse effects on the heart, which are further correlated with exercise dose. However, its effect on the right ventricle (RV) of amateur runners is unknown. This study aimed was to evaluate the early right ventricular structure and systolic function of amateur marathon runners by three-dimensional speckle tracking echocardiography (3D-STE), and to further analyze the correlation between relevant parameters and the amount of training. A total of 30 amateur marathon runners (marathon group) and 27 healthy volunteers (control group) were enrolled. Conventional echocardiography combined with 3D-STE was performed in all subjects, and the marathon group was screened by echocardiography a week before a marathon (V1), within 1 h post-marathon (V2), and 4 days post-marathon (V3). RV global longitudinal strain (GLS) and RV end-diastolic volume (EDV) increased significantly in the marathon group compared to the control group (P < 0.05). RV GLS was significantly decreased in the marathon group within 1 h post-marathon (V1: − 26.2 ± 2.5% vs V2: − 23.0 ± 1.6% vs V3: − 25.6 ± 2.6%, P < 0.001). However, there was no significant difference in RV ejection fraction (RVEF) (P > 0.05). The results of the correlation analysis showed that RV EDV and RV end-systolic volume (ESV) were positively correlated with the average training volume (P < 0.001). Multivariate linear regression analysis showed that average training volume was an independent predictor of RV EDV in amateur marathoners (β = 0.642, P < 0.001). The systolic function of the RV was enhanced in amateur marathon runners in the early stage, manifested by an increase in RV EDV. After a long period of high-intensity endurance exercise, RV systolic function will temporarily be reduced. 3D-STE can identify this subclinical change with high sensitivity and provide valuable information to assess the structure and function of RV in amateur marathon runners.
Sparse conic reformulation of structured QCQPs based on copositive optimization with applications in stochastic optimization
Authors: Gabl Markus 
Published: May 2023

AbstractRecently, Bomze et al. introduced a sparse conic relaxation of the scenario problem of a two stage stochastic version of the standard quadratic optimization problem. When compared numerically to Burer’s classical reformulation, the authors showed that there seems to be almost no difference in terms of solution quality, whereas the solution time can differ by orders of magnitudes. While the authors did find a very limited special case, for which Burer’s reformulation and their relaxation are equivalent, no satisfying explanation for the high quality of their bound was given. This article aims at shedding more light on this phenomenon and give a more thorough theoretical account of its inner workings. We argue that the quality of the outer approximation cannot be explained by traditional results on sparse conic relaxations based on positive semidenifnite or completely positive matrix completion, which require certain sparsity patterns characterized by chordal and block clique graphs respectively, and put certain restrictions on the type of conic constraint they seek to sparsify. In an effort to develop an alternative approach, we will provide a new type of convex reformulation of a large class of stochastic quadratically constrained quadratic optimization problems that is similar to Burer’s reformulation, but lifts the variables into a comparatively lower dimensional space. The reformulation rests on a generalization of the set-completely positive matrix cone. This cone can then be approximated via inner and outer approximations in order to obtain upper and lower bounds, which potentially close the optimality gap, and hence can give a certificate of exactness for these sparse reformulations outside of traditional, known sufficient conditions. Finally, we provide some numerical experiments, where we asses the quality of the inner and outer approximations, thereby showing that the approximations may indeed close the optimality gap in interesting cases.
Gradient Robust Mixed Methods for Nearly Incompressible Elasticity
Authors: Basava Seshadri R. , Wollner Winnifried 
Published: May 2023

AbstractWithin the last years pressure robust methods for the discretization of incompressible fluids have been developed. These methods allow the use of standard finite elements for the solution of the problem while simultaneously removing a spurious pressure influence in the approximation error of the velocity of the fluid, or the displacement of an incompressible solid. To this end, reconstruction operators are utilized mapping discretely divergence free functions to divergence free functions. This work shows that the modifications proposed for Stokes equation by Linke (Comput Methods Appl Mech Eng 268:782–800, 2014) also yield gradient robust methods for nearly incompressible elastic materials without the need to resort to discontinuous finite elements methods as proposed in Fu et al. (J Sci Comput 86(3):39–30, 2021).

Published: May 2023

AbstractYouth of immigrant origin vary across their families’ migration history (e.g., country of heritage, reasons for migration, etc.) and in the communities in which they reside. As such, these youth are often faced with different cultural and immigrant stressors. Although prior research documented the detrimental impact of cultural and immigrant stressors, variable-centered approaches fail to account for the fact that these stressors often co-occur. Addressing this gap, the current study identified typologies of cultural stressors in Hispanic/Latino adolescents using latent profile analysis. Cultural stress profiles were derived using socio-political stress, language brokering, in-group identity threats, and within-group discrimination as indicators. The study was conducted in two sites (Los Angeles and Miami; total N = 306) during Spring and Summer 2020. A four-profile solution was identified: Low Cultural Stress (n = 94, 30.7%), Sociopolitical and Language Brokering Stress (n = 147, 48%), Sociopolitical and In-group Identity Threat Stress (n = 48, 15.7%), and Higher Stress (n = 17, 5.6%). Results indicate that profiles with stress were characterized by worse mental health symptoms, reporting higher means of depression, stress, and lower self-esteem, as well as by higher heritage cultural orientation compared to the low stress profile. Interventions designed to mitigate the deleterious effects of cultural stressors would benefit from adopting an individualized, tailored approach that addresses youth’s stress profile membership.
The vertebrate muscle superlattice: discovery, consequences, and link to geometric frustration
Authors: Millane Rick P. , Luther Pradeep K. 
Published: May 2023

AbstractEarly x-ray diffraction studies of muscle revealed spacings larger than the basic thick filament lattice spacing and led to a number of speculations on the mutual rotations of the filaments in the myosin lattice. The nature of the arrangements of the filaments was resolved by John Squire and Pradeep Luther using careful electron microscopy and image analysis. The intriguing disorder in the rotations, that they termed the myosin superlattice, remained a curiosity, until work with Rick Millane and colleagues showed a connection to “geometric frustration,” a well-known phenomenon in statistical and condensed matter physics. In this review, we describe how this connection gives a satisfying physical basis for the myosin superlattice, and how recent work has shown relationships to muscle mechanical behaviour.
Adaptation and illness severity: the significance of suffering
Authors: Jølstad Borgar 
Published: May 2023

AbstractAdaptation to illness, and its relevance for distribution in health care, has been the subject of vigorous debate. In this paper I examine an aspect of this discussion that seems so far to have been overlooked: that some illnesses are difficult, or even impossible, to adapt to. This matters because adaptation reduces suffering. Illness severity is a priority setting criterion in several countries. When considering severity, we are interested in the extent to which an illness makes a person worse-off. I argue that no plausible theory of well-being can disregard suffering when determining to what extent someone is worse-off in terms of health. We should accept, all else equal, that adapting to an illness makes the illness less severe by reducing suffering. Accepting a pluralist theory of well-being allows us to accept my argument, while still making room for the possibility that adaptation is sometimes, all things considered, bad. Finally, I argue that we should conceptualize adaptability as a feature of illness, and thereby account for adaptation on a group level for the purposes of priority setting.
The Timing of Technology Adoption in Network Industries
Authors: Wang Leonard F. S. , Buccella Domenico 
Published: May 2023

AbstractThis paper analyzes the effect of network externalities on firms’ timing of new technology adoption in a network industry. In a pre-commitment game under Cournot competition, network effects tend to accelerate the timing of the leader and the follower regarding their adoption dates: under the rational expectations hypothesis and also under the firms’ output commitment. However, while an increase in network effects tends to reduce the discrepancy between the optimal social timing of the new technology adoption and the market-driven time of adoption in the rational expectations model, the opposite occurs under the output commitment game.
Paradoxes of accelerator programs and new venture performance: Do varieties of experiences make a difference?
Authors: Chowdhury Farzana , Audretsch David B. 
Published: May 2023

Abstract
Incubators and accelerators have proliferated, but their impact on new ventures’ performance remains unclear. This article explores whether all ventures benefit equally from participating in accelerator programs. We propose that the entrepreneurs’ human capital resources influence the benefits extracted from accelerator program participation. Using application data from the accelerator programs across developed and developing countries, we find participation in accelerator programs positively impacts the ventures’ innovation performance but has a mixed impact on social performance. Founders with high education benefit from participating in accelerator programs for innovation and social performance. However, entrepreneurial experience and vast industry experience do not significantly influence ventures’ social and innovation-related performance from accelerator participation. The result is consistent for both solo and team founders.
Let’s Talk About Single Men: A Qualitative Investigation of Never Married Men’s Experiences of Singlehood
Authors: Mrozowicz-Wrońska Marta , Janowicz Kamil , Soroko Emilia , Adamczyk Katarzyna 
Published: May 2023

AbstractExisting research on singlehood has largely focused on the experiences of single women, and little is known about singlehood among men. The current investigation examined the experience of long-term singlehood through individual, semi-structured interviews with 22 never-married single men living in Poland who were aged 22–43 years. Thematic analysis revealed five key themes: (1) the sense of being deficient—is there something wrong with me?; (2) navigating outside the dominant discourse of traditional masculinity, marriage and family; (3) the benefits and downsides of singlehood; (4) adaptation to singlehood; and (5) the dilemma between waiting and actively searching for a romantic partner. An analysis of single men’s narratives revealed that men experience their single status in the context of their various needs and hopes and as a status that determines their adult life course. This study contributes to the singlehood literature, highlighting the complexity of singlehood for men and the importance of traditional masculinity norms in experiencing long-term singlehood.These findings challenge stereotypical and unrealistic views of singlehood among men and have practical implications for psychotherapists, counsellors and educators working with single men.

AbstractMany of the more than 27 million refugees in the world today are highly educated professionals, but resolving their displacement via skilled migration pathways is typically not possible. At the request of employers facing severe skill shortages and the coordination of Talent Beyond Boundaries (TBB)–a non-profit organisation–the Australian government introduced in 2018 a pilot program enabling employers to sponsor refugees through an employment contract meeting existing skilled visa requirements. The pilot effectively added immigration places to refugees, as employer-sponsored visa are uncapped in Australia. We highlight some insights collected from TBB’s 2018 and subsequent pilots.
A Systems Thinking Approach for Community Health and Wellbeing

AbstractUnder national or state-based legislation, local governments are commonly required to prepare municipal health and wellbeing plans. Yet, the issues these plans aim to address are often complex, and programmatic planning approaches traditionally used by practitioners struggle to engage with such complexity as they assume these issues can be ‘solved’ in isolation. Systems thinking is increasingly being used as an approach to deal with those struggles more effectively, yet little is known about whether local governments and other stakeholders think systems approaches are feasible and acceptable in practice. This study tested a systems thinking approach to gauge if it could better address complex place-based health and wellbeing issues, such as to reduce noncommunicable diseases. Guided by a systems change framework, the approach comprised a facilitated systemic inquiry and rich picture process involving diverse stakeholders in a remote municipality in the Australian state of Tasmania. Among the participants there was broad support for the systems approach tested and they thought it was effective for increasing systems thinking capacity, collaboratively revealing systemic issues, and identifying opportunities to address those issues. They valued the rich picture because it created shared understandings of local issues. The findings suggest more is needed from macro-level policy to support place-based stakeholders to undertake systems approaches in practice, which could result in more sustainable and effective systems change required to improve health and wellbeing outcomes. The findings have implications for theory, research, and practice across interdisciplinary fields concerned with placed-based systems change, especially in rural and remote municipalities.
Advice as a Form of Structural Coupling: Intersystem Organizations and Scientific Communication in the Japanese Response to COVID-19
Authors: Sakai Kosuke 
Published: May 2023

AbstractA critical issue in the study of scientific communication from a systems theoretical perspective is its role in multiple intersystem relationships. During COVID-19, politics has adopted scientific findings to inform political decisions. However, science has in response actively coordinated its operations for providing desired stimuli to politics. Luhmann identified advice as a form of structural coupling that links political and scientific systems. Advice is not a monolithic intervention by which one side acts on the other but is rather an interface that enables the two systems to relate through distancing. In this article, I empirically illustrate how the structural coupling of the political system and scientific system through advice manifests itself in an examination of the roles that various organizations (expert meeting and cluster task forces) have played in Japan’s response to COVID-19. Through this analysis, I provide a theoretical insight regarding these organizations and a more detailed case analysis of the transformation of certain organizations to re-describe the system theoretical insights of advice in the form of scientific communication between politics and science.
Agamemnon at Aulis: On the Right and Wrong Sorts of Imaginative Identification
Authors: Chappell Sophie-Grace 
Published: May 2023

AbstractWilliams’ discussion of dilemmas in his classic paper “Ethical consistency” famously focuses on an example that has not bothered commentators on and respondents to Williams as much as it should have bothered them: the example of Agamemnon in Aeschylus’ play. In this paper I try to pick apart what Williams wants to say from what is really going on in the text that he unfortunately chooses for his example. I compare with Williams’ discussion of Agamemnon four other commentators on this crucial passage in Aeschylus’ play: Plato, Socrates, Aristotle—and Bernard Williams’ Greats tutor Eduard Fraenkel, whose epochal Corpus Christi seminars on the play Williams attended (along with Iris Murdoch, Hugh Lloyd Jones, and other rising stars of the time). I shall argue that these commentators led Williams astray. They are surprisingly prone to the same flaws of rationalism, impersonality, and moralism in making sense of Aeschylus’ extraordinarily subtle and brilliant depiction of Agamemnon; and Williams’ discussion inherits these flaws. This is an obviously ironic fact, especially given that a very fruitful reading of the passage—one that I think makes much better sense of what Aeschylus actually says—points a deeply Williamsian moral. It takes Agamemnon at Aulis as a study of a key step in the corruption of a character, a study that gets its power and its horror from its ability to show us how that process looks from Agamemnon’s own viewpoint.
