Published: April 2022

AbstractMany core marketing concepts (e.g., markets, relationships, customer experience, brand meaning, value) concern phenomena that are difficult to understand using linear and dyadic approaches, because they are emergent. That is, they arise, often unpredictably, from interactions within complex and dynamic contexts. This paper contributes to the marketing discipline through an explication of the concept of emergence as it applies to marketing theory. We accomplish this by first drawing on the existing literature on emergence in philosophy, sociology, and the theory of complex adaptive systems, and then link and extend this understanding to marketing using the theoretical framework ofservice-dominant (S-D) logic,particularly as enhanced by its service-ecosystems and institutionalization perspectives. Our work recognizes both emergence and institutionalization as integral or interrelated processes in the creation, maintenance, and disruption of markets and marketing phenomena. We conclude by discussing implications for marketing research and practice.

Published: April 2022

AbstractThe recognition of pavement cracks is crucial in road engineering and airport maintains. In order to successfully apply image processing technique for automatic crack detection, the first and hardest task is to recognize crack images in a huge number of pavement images. To do this, the image processing technique and Fracture mechanics are combined first time in this area, the studied method includes four steps: (1) The pavement crack image shrinking is carried out by a proposed multi-scale analysis algorithm, which is more effective for both preserving weak valley edges and reducing computing cost; (2) Then, a so called valley edge detection algorithm based on Fractional differential for finding local dark line/curve is studied for tracing crack segments, it considers template size, weighted average gray level value in each line in four different directions, the output can be a gradient magnitude image or a binary image; (3) In the binary image, the crack segments are refined based on a number of post processing functions to remove noise and fill segment gaps; and (4) After that, to quickly judge if the image has cracks, Fracture mechanics is applied to calculate the judgment parameter T, which is directly proportion to the image edge density, and the ratio between the average gradient magnitude value and the average gray level value in the candidate crack segment. In experiments, more than 400 pavement images (the resolution is 4096 × 2048 pixels) are tested, and the crack identification accuracy is up to 97%.

AbstractWorldwide, quality registries for cardiovascular diseases enable the use of real-world data to monitor and improve the quality of cardiac care. In the Netherlands Heart Registration (NHR), cardiologists and cardiothoracic surgeons register baseline, procedural and outcome data across all invasive cardiac interventional, electrophysiological and surgical procedures. This paper provides insight into the governance and processes as organised by the NHR in collaboration with the hospitals. To clarify the processes, examples are given from the percutaneous coronary intervention and coronary artery bypass grafting registries. Physicians who are mandated by their hospital to instruct the NHR to process their data are united in registration committees. The committees determine standard sets of variables and periodically discuss the completeness and quality of data and patient-relevant outcomes. In the case of significant variation in outcomes, processes of healthcare delivery are discussed and good practices are shared in a non-competitive and safe setting. To create new insights for further improvement in patient-relevant outcomes, quality projects are initiated on, for example, multivessel disease treatment, cardiogenic shock and diagnostic intracoronary procedures. Moreover, possibilities are explored to expand the quality registries through additional relevant indicators, such as resource use before and after the procedure, by enriching NHR data with other existing data resources.
De realiteit van overleven

SamenvattingWelvaart en gezondheid hangen onlosmakelijk met elkaar samen. Beleid om gezondheidsverschillen te verkleinen heeft zich lang gericht op individuele levensstijl, maar de laatste jaren neemt de aandacht voor de invloed van inkomenszekerheid, huisvesting, en de sociale en fysieke leefomgeving op gezondheid weer toe. In dit artikel staan we stil bij de relatie tussen bestaansonzekerheid, gezondheid én de manier waarop de overheid hieraan bijdraagt. De onderzoeksvraag wordt beantwoord door het analyseren van vijftien biografische interviews met mensen in bestaansonzekerheid in drie verschillende levensfasen: jong (18–30 jaar), midden (30–50 jaar), oud (50–70 jaar). De interviews geven een veelzijdig beeld van bestaansonzekerheid. De dynamiek die inherent is aan bestaansonzekerheid zorgt voor onduidelijke grenzen en onduidelijkheid in causale relaties, vooral waar het gezondheid betreft. Als gevolg van bestaansonzekerheid komen mensen in een ‘overlevingsmodus’ terecht. Hulp vanuit de overheid is vaak slecht toegankelijk vanuit de ervaring van de respondenten. Dit is zorgelijk, omdat juist de overlevingsmodus op de langere termijn meer risico’s op gezondheidsproblemen met zich meebrengt. De resultaten van ons onderzoek geven aanleiding tot drie bespiegelingen. Ten eerste is er de noodzaak om breder te denken over gezondheid en preventie. Daarnaast vergt de aanpak van gezondheidsachterstanden meer proactieve hulp. Tot slot moeten we meer onderscheid durven maken als het gaat om de hulp die wordt aangeboden.
„Shut up and dribble“ – zur Legende des „mündigen Athleten“
Authors: Stiller Timo 
Published: April 2022

ZusammenfassungWird die unspezifische Idee des „mündigen Athleten“ allseits zur Legitimation des Spitzensports und dessen Förderung bemüht, führt die konkrete Personifizierung der Mündigkeit nicht nur den Athleten selbst, sondern den Spitzensport an sich in ein Spannungsfeld. Ausgehend von einer hermeneutischen Analyse der Mündigkeit wird dargelegt, dass der Druck dieses Spannungsfelds umso größer ist, je zweckrationaler die Systemlogik des Spitzensports ausschließlich auf den Erfolg reduziert wird und mündige Athleten im Gegensatz zu erfolgreichen Athleten für den Spitzensport allenfalls wünschenswert, aber in keiner Weise notwendig sind. Konsequenterweise werden für die Zukunft des Spitzensports dann zwei Optionen zur Diskussion gestellt, von denen allein eine den Spitzensport und dessen Förderung in einer Zivilgesellschaft wie der Bundesrepublik Deutschland legitimiert. Dies setzt jedoch eine Ausweitung der Zielebene des Spitzensports voraus, in der die Idee der Mündigkeit dahingehend konkretisiert wird, weniger den Erfolg als vielmehr die Leistung einer reflexiven Auseinandersetzung mit dem eigenen spitzensportlichen Streben ins Zentrum zu rücken. Derartige Persönlichkeiten dürften dann tatsächlich als würdige Repräsentanten einer zivilgesellschaftlichen Leistungselite gelten und dann natürlich auch entsprechend gefördert werden.
A digital career choice: rural students’ perceptions of the value of digital media learning based on their career aspirations
Authors: Turner Krystle 
Published: April 2022

AbstractDigital media skills are becoming more important in contemporary Australia. As the digital economy gains momentum, the 2020 Australian Digital Inclusion Index reports a continued gap between rural Australians and urban Australian, indicating the continued existence of the digital divide. However, almost half of all Year 10 Australian students did not have sufficient information and communication technology (ICT) skills in 2014. Thus, understanding how rural students who are interested in digital media careers learn and develop digital media skills is important for improving digital media education for isolated student groups. This research draws on 25 interviews with rural Queensland students contemplating careers both within and outside digital media industries. The findings show different forms of cultural capital students draw on to further their digital media skills, including extracurricular opportunities and self-learning. This research highlights the interviewed students’ perceptions of the value of digital media learning based on their career aspirations.
Teachers’ representations of genders and sexualities in primary school: the power of curriculum and an institutional ideological code
Authors: van Leent Lisa , Spina Nerida 
Published: April 2022

AbstractTexts such as curriculum and policy documents work in complex ways to coordinate teachers’ work and approaches to diverse genders and sexualities. Although it might be assumed that official, mandated curricula determine teachers’ curriculum choices, little is known about the extent of textual influences on how teachers represent genders and sexualities in primary schooling. This institutional ethnographic study investigated how the Australian national curriculum coordinated teachers’ curriculum decisions in one Australian primary school. Drawing on the work of Dorothy E. Smith, we found that teachers and school leaders use multiple institutional texts to guide curriculum choices. Although diverse genders and sexualities are visible in the Australian Curriculum (minimally so), we found curriculum and related policy texts were shaped by an ideological code that conceals diverse sexualities and genders. We argue that dominant hetero-cis-normative practices embedded in chains of texts remain powerful, shaping representations of genders and sexualities in primary schooling.

AbstractObjectiveBlack and Latinx/Hispanic people were more than twice as likely to die from COVID-19 than White people, but because of legacies of discrimination and maltreatment in health care, were less likely to participate in some public health responses to COVID-19, including contact tracing. This study aimed to test three communication campaign concepts to engage Black and Latinx/Hispanic people in contact tracing efforts.MethodsTwelve focus group discussions with 5 to 10 participants each were conducted online among participants from Black and Latinx/Hispanic urban populations in Philadelphia and New York state. Participants provided sociodemographic information and were presented with potential campaign concepts and prompted to rate the concepts and engage in open-ended discussion. For rating and sociodemographic data, chi-square tests were performed. For open-ended discussion data, a thematic analysis approach was used.ResultsAcross groups, the campaign concept that was rated most likely to encourage cooperation with contact tracing efforts was “Be the One,” with 45% of total first-place votes. Participants expressed that the campaign caught their attention (79%), motivated them to engage with contact tracers (71%) and to talk to others about contact tracing (77%). Discussions also elucidated: the importance of community engagement; the need for clearer explanations of contact tracing; the preference for already trusted, community-based contact tracers; the need to reassure people about confidentiality; and for contact tracing to be culturally competent and empathetic.ConclusionsThis study highlights how strategic, culturally sensitive communication can buttress current and future contact tracing efforts, especially among Black and Latinx/Hispanic people.

AbstractHaloxylon ammodendron is an excellent windproof and sand-fixing species whose shrubs are widely cultivated in arid desert areas of northwest China but are now at risk of degradation and shrinkage. Using the chlorophyll fluorescence image analysis technique, the response of photosystem II (PSII) photochemical efficiency and non-photochemical quenching capacity to sediment-carrying wind and sand-free wind (both 12 m s−1) lasting for 10, 20, and 40 min were studied with seedlings in a wind tunnel. The results indicated that the sand-free wind had little influence on the maximum quantum efficiency of PSII photochemistry, Fv/Fm, which was approximately 0.80 on average; however, the Fv/Fm decreased over exposure time in the sediment-carrying wind group, with values smaller than those in the wind-only group. The non-photochemical quenching was sensitive to wind erosion, and sediment-carrying wind could aggravate the reduction in non-photochemical quenching (NPQ). Except for the 10 min duration, the maximum quantum efficiency of PSII photochemistry after dark recovery for 15 min, Fvr/Fmr, was lower in seedlings exposed to sediment-carrying wind than in those in the wind-only group. Compared to wind-only, wind-blown sand led to a water imbalance and withering in seedlings, causing the concentration of photosynthetic pigments (when based on the fresh mass of green branches) to not decrease. With a longer exposure time to sediment-carrying wind, both the probability and extent of lignified spots occurring increased in green assimilative branches. Our results demonstrated that sediment-carrying wind at 12 m s−1 lasting for 20 min or more could cause irreversible damage to the photosynthetic apparatus of H. ammodendron seedlings. Therefore, frequent and strong sandstorms are the main disturbance factors leading to shrinkage of shrubs and limiting their self-renewal.
Localized Mixing Zone for Muskat Bubbles and Turned Interfaces
Authors: Castro Á. , Faraco D. , Mengual F. 
Published: April 2022

AbstractWe construct mixing solutions to the incompressible porous media equation starting from Muskat type data in the partially unstable regime. In particular, we consider bubble and turned type interfaces with Sobolev regularity. As a by-product, we prove the continuation of the evolution of IPM after the Rayleigh–Taylor and smoothness breakdown exhibited in (Castro et al. in Arch Ration Mech Anal 208(3):805–909, 2013, Castro et al. in Ann Math. (2) 175(2):909–948, 2012). At each time slice the space is split into three evolving domains: two non-mixing zones and a mixing zone which is localized in a neighborhood of the unstable region. In this way, we show the compatibility between the classical Muskat problem and the convex integration method.
On the growth impact of different eco-innovation business strategies
Authors: Caravella Serenella , Crespi Francesco 
Published: April 2022

AbstractThe paper investigates whether standard innovation and different types of eco-innovation activities have different effects on firm employment growth. Heterogeneity in terms of growth effects is analyzed by considering how the influence of different innovation strategies varies across firms grouped by their pace of growth. Relying on a sample of 3000 Italian manufacturing firms observed between 2012 and 2016, we find that innovative companies tend to grow faster than their non-innovative counterparts. However, when distinct paces of growth are taken into account, the employment growth impact of innovation will depend on the specific types of innovation strategies pursued by companies. In particular, more complex eco-innovation activities have no impact on employment growth for high-growth firms. This finding suggests that, on average, high-growth firms tend to be too small and too young to be able to expand through more complex EI strategies which, to be handled, require a wide range of cognitive, technological, and financial capabilities.

AbstractAdditive manufacturing and especially the laser-based powder bed fusion (LPBF) with full melting of the powder offers tremendous potential and versatility for manufacturing high quality, complex, precision metal parts. However, for novel powder compositions the LPBF process development is very time consuming and cost intensive due to the layer wise melting and the powder prices. This research work investigates the manufacturing of single and layered multi-material structures in a novel modular lab-scaled LPBF machining system through individual process and material development. The developed system allows the use of different laser sources, optical arrangements, individual sensor and actuator integration. In addition, the modular LPBF system enables the manufacturing of specimens with a minimum amount of powder, individual mixed powder compositions or layered multi-material parts. In an application example, a multi-material specimen made out of stainless steel 316L and Bronze 90/10 was manufactured in alternating layers. For this approach, a parameter study was performed for each material to investigate the influence of the volumetric energy density (VED) on the specimen density, surface flatness and reduced mixing zone formation. Afterwards, optimized parameters were used to demonstrate the feasibility of the system to produce a multi-material layered 316L-Bronze part.
Time Trends and Persistence in US Sea Level Data: An Investigation Using Fractional Integration Methods

Published: April 2022

AbstractThis paper analyses US sea level data using long memory and fractional integration methods. Specifically, monthly data for 41 US stations covering the period from January 1950 to December 2018 are examined. Fractional integration methods suggest that all series exhibit orders of integration in the interval (0, 1), which implies long-range dependence with positive values of the differencing parameter; further, significant positive time trends are found in the case of 29 stations located on the East Coast and the Gulf of Mexico, and negative ones in the case of four stations on the North West Coast, but none for the remaining 8 on the West Coast. The highest degree of persistence is found for the West Coast stations and the lowest for the East Coast ones. Thus, in the event of shocks, more decisive action is required in the case of West Coast stations for the series to revert to their original trend.
Neither Threat of Shock nor Acute Psychosocial Stress Affects Ambiguity Attitudes

Published: April 2022

AbstractDecisions under uncertainty can be differentiated into two classes: risky, which has known probabilistic outcomes, and ambiguous, which has unknown probabilistic outcomes. Across a variety of types of decisions, people find ambiguity extremely aversive, subjectively more aversive than risk. It has been shown that the transient sympathetic arousal response to a choice predicts decisions under ambiguity but not risk, and that lifetime stress uniquely predicts attitudes toward ambiguity. Building on these findings, this study explored whether we could bias ambiguity and risk preferences with an arousal or acute stress manipulation that is incidental to the choice in two independent experiments. One experiment induced sympathetic arousal with an anticipatory threat paradigm, and the other manipulated incidental acute stress via a psychosocial stressor. The efficacy of the manipulations was confirmed via pupil dilation and salivary cortisol, respectively. Participants made choices between a guaranteed $5 option and a lottery with either a known (risky) or unknown (ambiguous) probabilistic outcome. Consistent with previous findings, participants were more averse to a given level of ambiguity than to a numerically equal level of risk. However, in contrast to our hypothesis, we found no evidence that transient arousal or acute stress that is incidental to the choice biases ambiguity preferences.
Asymmetrical Effects of Sleep and Emotions in Daily Life

Published: April 2022

AbstractSleep is an important process that can influence and be influenced by daily events and emotions. We examined the bidirectional relationships between sleep, daily events, and emotions with a daily diary method completed by 181 mothers (Mage = 41.91, SD = 5.06). They answered morning and evening questionnaires for 1 week at three different points in time separated by nine months each, 21 days in total. Measures of sleep quality and emotional experiences each morning were assessed, and they reported on their best and worst experience of the day, peak emotional responses to these events, and affect in the evening. Sleep behavior, including total sleep time and sleep efficiency, was objectively quantified using wrist actigraphy. Multilevel modeling analyses showed that longer sleep duration and better subjective quality predicted greater positive emotions and lower negative emotions upon waking, and lower levels of peak perceived stressfulness, but not peak positivity ratings. Daily experiences did not predict sleep duration. Conversely, negative affect in the evening and greater peak perceived stressfulness during the day predicted worse sleep quality that night, whereas positive affect and positive events were not related to sleep. Although correlational, these findings suggest that good sleep can improve waking affect and help mitigate the impact of stressful experiences but does not amplify responses to the positive events of the day. In turn, daily perceived stress reactivity impairs sleep quality. These novel findings show stronger bidirectional relationships between sleep with daily stress, than sleep with daily positivity.
