Absorptive capacity and NPD: salient issues in bipolar entrepreneurial SMEs
Authors: Popaitoon Sujinda , Yanpiboon Tanyanart , Tapjarern Chutikarn 
Published: July 2021

PurposeThe purpose of this study is to explore knowledge absorptive capacity (ACAP) (both potential and realized) and new product development (NPD) in bipolar entrepreneurial small- and medium-sized enterprises (SMEs).Design/methodology/approachIn response to recent calls for research on knowledge ACAP and NPD in entrepreneurial SMEs, particularly in different contexts, this research aims to answer a specific question: What are the characteristics of ACAP (both potential and realized) and the salient issues concerning working complementarily between both types of ACAP to foster NPD in bipolar entrepreneurial SMEs (in this case, three new low-tech and three established high-tech cases)? The authors conduct case study research based on cross-case and within case analyses to answer the question.FindingsThe findings show that, in the established high-tech cases, realized ACAP plays an outsized role in developing new products and prior-related knowledge acts as a precondition for capturing useful knowledge from external sources (potential ACAP). On the contrary, in the new low-tech cases, potential ACAP is the key driver of NPD, so external knowledge from network ties becomes a crucial source of acquiring new knowledge, along with entrepreneurs’ level of skill at applying useful knowledge (realized ACAP) to achieve NPD.Research limitations/implicationsOn the basis of the bipolar entrepreneurial SMEs (i.e. established high-tech and new low-tech ventures), the characteristics of entrepreneurial SMEs (i.e. firm’s age, size and level of technology) affect the different roles of realized and potential ACAP in driving NPD successes. Realized ACAP plays a critical role for NPD in established high-tech SMEs, whereas potential ACAP is the main driver of NPD in new low-tech SMEs. This research has some limitations that future research should conduct quantitative research in other industries’ context as well as in other countries.Practical implicationsFor new ventures, they should be aware that to strengthen their network ties with customers and suppliers can be an important tool for not only overcoming their limitations of existing knowledge but also acquiring tacit knowledge from the external sources. For established high-tech ventures, they should focus not only on the short-term NPD (the achievement of current NPD) but also the long-term NPD (e.g. series of new products and new strategic alliances) that can help avoid a not-invented-here syndrome situation.Social implicationsThe government should customize the policy to suit each targeted SME. Policymakers should play a crucial role of a linking pin among key external sources (e.g. R&D national and international institutions, SME banks and marketing agents) in different stages of the business cycle.Originality/valueThis research contributes to the literature of knowledge ACAP in SMEs to the understanding of the distinction roles of potential and realized ACAP as a mechanism in the different natures of entrepreneurial SMEs.
On the complexities of studying sensitive communities online as a researcher–participant
Authors: Hård af Segerstad Ylva 
Published: July 2021

Purpose
This study aims to explore the complexities of methodological, ethical and emotional challenges of studying sensitive and vulnerable communities online from the perspective of simultaneously being a researcher and a research subject. The point of departure for these explorations consists of the author’s past and ongoing studies of the role and use of a closed grief support group on Facebook for bereaved parents – a community of which the author is a member. The aim is not to provide ready solutions for “how to do ethics,” but rather to contribute to the collective and ongoing work initiated by the Association of Internet Researchers (AoIR), among others, and to recognize the necessity of ethical pluralism, cross-cultural awareness and an interdisciplinary approach.

Design/methodology/approach
This is an explorative study, drawing on an (auto)ethnographic case study. The case serves as a point of departure for discussing the complexities of methodological, ethical and emotional challenges of studying sensitive and vulnerable communities online from the perspective of simultaneously being a researcher and a research subject.

Findings
Being a researcher and a research subject rolled into one, as it were, presents both opportunities and challenges. To conduct responsible research from both these perspectives pose high demands on the researchers’ ethical as well as emotional capacities and responsibilities. Hopes and expectancies of the community under study might put the researcher into a dilemma, ethical aspects of anonymity and informed consent might have to be reconsidered as well as emotional challenges of engaging in and with sensitive research, all of which makes for a complex balancing act. Ethics and methods are inextricably intertwined, so are the emotional challenges of conducting sensitive research intermingled. Studying vulnerable individuals and closed communities online highlights the necessity for case and context sensitive research and for flexibility, adaptivity and mindfulness of the researcher. It also highlights the importance of discussing and questioning theoretical, methodological and ethical developments for studying everyday life practices online.

Originality/value
The challenges encountered in this case study contribute to the experientially grounded approach to research ethics emphasized in AoIR’s ethics guidelines. This case offers an opportunity to explore and discuss complex issues arising from the researcher’s insider position in a closed group devoted to the sensitive topic of supporting bereaved parents. Further, it highlights the necessity for research to be case and context sensitive as well as for the researcher and the research design to be flexible and adaptive. Research on vulnerable communities also heightens the demands of ethical responsibility of the researcher and the research process.
Investors' reactions to COVID-19 related announcements: evidence from the cargo shipping industry
Authors: Marobhe Mutaju Isaack 
Published: July 2021

PurposeThe purpose of this study is to examine the impact of the corona virus (COVID-19) pandemic on stock returns of listed cargo shipping companies.Design/methodology/approachThe author employs the events study methodology to examine this phenomenon. A sample of 49 listed cargo shipping companies in the container, dry bulk and tanker sub-sectors from Asia, North America, and Europe was selected and their daily closing stock prices from 1st January 2020 to 31st December 2020 were utilized.FindingsThe results reveal that there was an overall negative overreaction to the announcement by World Health Organization (WHO) that declared COVID-19 a pandemic. The approvals of USD 857 billion stimulus package by the European Union (EU) and Pfizer vaccine by Food and Drug Administration (FDA) in USA received slight positive reactions. The Greek, Singaporean and Taiwanese shipping stocks were the least affected stocks as their respective shipping industries remained resilient during 2020.Research limitations/implicationsThis study provides evidence to confirm the fact that COVID-19 has affected stock markets; however the impact is un parallel among cargo shipping stocks of different countries.Originality/valueThe majority of studies have conducted country level analyses of the COVID-19 and stock market performance phenomenon. However, there have been sectoral disparities in terms of their susceptibility to economic shocks from COVID-19. This study's focal point is on the cargo shipping sector which synonymous with other sectors has not been immune to the current pandemic. The study also extends the timeline of events to incorporate those from June to December 2020.
Global value chain linkages and domestic value-added content: Empirical evidence
Authors: Jangam Bhushan Praveen , Rath Badri Narayan 
Published: July 2021

Purpose
This paper aims to examine the relationship between global value chains (GVCs) and domestic value-added content (DVA) in a panel of 58 countries for the period 2005–2015.

Design/methodology/approach
First, the authors quantify the refined measures of GVC linkages by using the Borin and Mancini (2019) decomposition technique. Second, the authors apply the feasible generalised least squares method to test the relationship between GVCs and DVA empirically.

Findings
First, the authors find that GVC links are crucial to the enhancement of DVA. Second, a study at the sectoral level reveals that GVC links in the primary sector raise DVA whilst reducing DVA in the services sector. Third, the authors find that only upstream activities enhance value-added content. Fourth, the authors note the augmenting role played by national policies in mediating the gains associated with GVCs. Finally, the authors note that the outcomes associated with GVCs are consistent when the sample of countries is divided into groups based on income.

Practical implications
The results lead us to urge policymakers to promote greater integration of business activities into GVCs to reap their benefits.

Originality/value
This paper contributes to the research on the impact of GVCs on DVA by emphasising the significance of the types of GVC activities and policies that improve DVA.

SummaryThe physical and biological dynamics that influence phytoplankton communities in the oligotrophic ocean are complex, changing across broad temporal and spatial scales. Eukaryotic phytoplankton (e.g., diatoms), despite their relatively low abundance in oligotrophic waters, are responsible for a large component of the organic matter flux to the ocean interior. Mesoscale eddies can impact both microbial community structure and function, enhancing primary production and carbon export, but the mechanisms that underpin these dynamics are still poorly understood. Here, mesoscale eddy influences on the taxonomic diversity and expressed functional profiles of surface communities of microeukaryotes and particle‐associated heterotrophic bacteria from the North Pacific Subtropical Gyre were assessed over 2 years (spring 2016 and summer 2017). The taxonomic diversity of the microeukaryotes significantly differed by eddy polarity (cyclonic versus anticyclonic) and between sampling seasons/years and was significantly correlated with the taxonomic diversity of particle‐associated heterotrophic bacteria. The expressed functional profile of these taxonomically distinct microeukaryotes varied consistently as a function of eddy polarity, with cyclones having a different expression pattern than anticyclones, and between sampling seasons/years. These data suggest that mesoscale forcing, and associated changes in biogeochemistry, could drive specific physiological responses in the resident microeukaryote community, independent of species composition.

SummaryExposure to a diverse microbial environment during pregnancy and early postnatal period is important in determining predisposition towards allergy. However, the effect of environmental microbiota exposure during preconception, pregnancy and postnatal life on development of allergy in the child has not been investigated so far. In the S‐PRESTO (Singapore PREconception Study of long Term maternal and child Outcomes) cohort, we collected house dust during all three critical window periods and analysed microbial composition using 16S rRNA gene sequencing. At 6 and 18 months, the child was assessed for eczema by clinicians. In the eczema group, household environmental microbiota was characterized by presence of human‐associated bacteria Actinomyces, Anaerococcus, Finegoldia, Micrococcus, Prevotella and Propionibacterium at all time points, suggesting their possible contributions to regulating host immunity and increasing the susceptibility to eczema. In the home environment of the control group, putative protective effect of an environmental microbe Planomicrobium (Planococcaceae family) was observed to be significantly higher than that in the eczema group. Network correlation analysis demonstrated inverse relationships between beneficial Planomicrobium and human‐associated bacteria (Actinomyces, Anaerococcus, Finegoldia, Micrococcus, Prevotella and Propionibacterium). Exposure to natural environmental microbiota may be beneficial to modulate shed human‐associated microbiota in an indoor environment.
Depressive symptoms and perception of risk during the first wave of the COVID‐19 pandemic: A web‐based cross‐country comparative survey
Authors: Terraneo Marco , Lombi Linda , Bradby Hannah 
Published: July 2021

AbstractEvidence is accumulating of the negative impact of the COVID‐19 pandemic and related public health measures on mental health. In this emergent field, there has been little research into the role of risk perception on depressive symptoms and the contribution of health‐care resources to model risk perception and mental health. The aim of this paper is to describe the relationship between individual‐level perception of risk and depression, controlling for a set of confounders and for country‐level heterogeneity. A cross‐sectional and observational online survey was conducted using a non‐probability snowball sampling technique. We use data on 11,340 respondents, living in six European countries (Italy, Sweden, United Kingdom, France, Poland, Czech Republic) who completed survey questionnaires during the first months of the pandemic. We used a fixed‐effect approach, which included individual and macro‐level variables. The findings suggest that a high proportion of people suffering from depression and heightened risk perception is positively associated with reporting depressive symptoms, even if this relationship varies significantly between countries. Moreover, the association is moderated by contextual factors including health‐care expenditure as a percentage of Gross Domestic Product, hospital beds for acute care, and number of medical specialists per head of population. Investment in health care offers a concrete means of protecting the mental health of a population living under pandemic restrictions.
Shotgun slug wads as a marker of range of fire: A case report and novel firearm testing data

Published: July 2021

AbstractAssessment of wound characteristics and the identification of various constituents of firearm discharge at autopsy play a key role in the determination of range of fire. In relation to wounds caused by shotguns, identification of the wad within the wound track, or of injury caused by the wad, is typically thought to suggest a fairly close range of fire. We present a case of a fatality due to a shotgun slug wound where the presence of the wad within the decedent's body was proposed by defense at criminal trial to favor accidental close range discharge during a struggle for the weapon—as opposed to the prosecution's contention of intentional firing of the weapon from a greater range and through an intermediate target. We undertook test firing of a shotgun of similar design to that which was fired during the interaction (a 12‐gauge pump‐action shotgun) using shotshells consistent with the slug that was recovered from the body (Winchester Super X brand), which demonstrated that the non‐attached fiber wad present in this shotshell design can accompany the slug over distances of at least up to 22 feet (6.7 m) and even after transit through intermediate targets such as a vehicle headrest. These novel data provide assistance with estimation of range of fire in instances of injuries caused by shotgun slugs.

AbstractSodium saccharin is a common artificial sweetener. However, due to its possible carcinogenic effects and causing metabolic disorders, many countries have strictly regulated its use in food. In the study, we prepared a specific monoclonal antibody (mAb 2H11) using the new hapten (6‐carboxylsaccharin) and developed a direct competitive enzyme‐linked immunosorbent assay (dcELISA) for the screening of sodium saccharin residue in food. The half‐maximum inhibition concentration (IC50) and working range (IC20–IC80, the concentrations causing 20% and 80% inhibition by sodium saccharin) were 32.5 and 6.47 to 164 ng/mL, which was 6.5 times more sensitive than the previously reported immunoassay. The average recoveries of sodium saccharin in spiked food samples detected by dcELISA ranged from 82.1% to 117%. Among 70 food samples bought in the physical stores and online, sodium saccharin residues were only detected in four samples purchased online (one canned pineapple, two winter jujube, and one kimchi). The content measured by dcELISA agreed well with those determined by ultra‐performance liquid chromatography‐tandem mass spectrometry (UPLC‐MS/MS). The developed dcELISA was proved to be a sensitive and accurate method for determining sodium saccharin in food.Practical ApplicationQuantitation of sodium saccharin residue in food is very necessary and important for consumers and regulatory agencies.
Inter‐Model Comparison of Delft3D‐FM and 2D HEC‐RAS for Total Water Level Prediction in Coastal to Inland Transition Zones

Published: July 2021

AbstractHydrodynamic models play a key role in simulating total water level (TWL), that is, a combination of river flow, tide, surge, wind and wave‐induced water level, and representing flood inundation dynamics in coastal areas. An appropriate selection of two‐dimensional (2D) models that integrate riverine and estuarine interactions with ocean dynamics is crucial to generate accurate TWL predictions and assist stakeholders and federal agencies in decision making and flood emergency responses. In this study, we compare the performance of two widely used hydrodynamic models (e.g., 2D HEC‐RAS and Delft3D‐Flexible Mesh [FM]) with respect to their ability of predicting TWL in Delaware Bay, United States. Based on a previously established model configuration, we simulate Hurricane Sandy and Isabel that affected the Bay and led to considerable damages and economic losses. We then evaluate model capabilities with tidal analysis, compare observed vs. simulated TWL and analyze spatiotemporal variations of TWL through scenario‐based simulations. Our results suggest that atmospheric forcing input in Delft3D‐FM significantly improves TWL predictions as compared to those of 2D HEC‐RAS. Furthermore, model simulations with Delft3D‐FM can be faster than 2D HEC‐RAS by a factor of 6–10. Despite these advantages, 2D HEC‐RAS (version 5.07) is a noncommercial software easier to implement and can be a simpler alternative for modeling extreme events when atmospheric forcing is not relevant in the model domain.

AbstractDisturbed oxygenation is foremost the leading clinical presentation in COVID‐19 patients. However, a small proportion also develop carbon dioxide removal problems. The Advanced Organ Support (ADVOS) therapy (ADVITOS GmbH, Munich, Germany) uses a less invasive approach by combining extracorporeal CO2‐removal and multiple organ support for the liver and the kidneys in a single hemodialysis device. The aim of our study is to evaluate the ADVOS system as treatment option in‐COVID‐19 patients with multi‐organ failure and carbon dioxide removal problems. COVID‐19 patients suffering from severe respiratory insufficiency, receiving at least two treatments with the ADVOS multi system (ADVITOS GmbH, Munich, Germany), were eligible for study inclusion. Briefly, these included patients with acute kidney injury (AKI) according to KDIGO guidelines, and moderate or severe ARDS according to the Berlin definition, who were on invasive mechanical ventilation for more than 72 hours. In total, nine COVID‐19 patients (137 ADVOS treatment sessions with a median of 10 treatments per patient) with moderate to severe ARDS and carbon dioxide removal problems were analyzed. During the ADVOS treatments, a rapid correction of acid‐base balance and a continuous CO2 removal could be observed. We observed a median continuous CO2 removal of 49.2 mL/min (IQR: 26.9‐72.3 mL/min) with some treatments achieving up to 160 mL/min. The CO2 removal significantly correlated with blood flow (Pearson 0.421; P < .001), PaCO2 (0.341, P < .001) and levels (0.568, P < .001) at the start of the treatment. The continuous treatment led to a significant reduction in PaCO2 from baseline to the last ADVOS treatment. In conclusion, it was feasible to remove CO2 using the ADVOS system in our cohort of COVID‐19 patients with acute respiratory distress syndrome and multiorgan failure. This efficient removal of CO2 was achieved at blood flows up to 300 mL/min using a conventional hemodialysis catheter and without a membrane lung or a gas phase.

AbstractAimThe aim of the study was to describe age‐ and sex‐specific prevalence of serious bacterial infections (SBI: urinary tract infection, bacteraemia, meningitis) among febrile infants ≤60 days in Sweden.MethodsThis is a retrospective study in 4 Pediatric Emergency Departments from 2014 to 2017, in previously healthy, full‐term infants ≤60 days with fever without a source.ResultsOf the 1,701 included infants, 214 (12.6%; 95% CI, 11.1–14.3) had an SBI. Urinary tract infection (UTI) was diagnosed in 196 (11.5%; 95% CI, 10.0–13.1) patients. In the ≤28 and 29–60 days age‐groups, meningitis prevalence was 0.9% (95% CI, 0.3–2.0) and 0.3% (95% CI, 0.1–0.8), whereas bacteraemia prevalence was 3.2% (95% CI, 1.9–4.9) and 0.6% (95% CI, 0.2–1.3). The SBI prevalence was higher in boys 16.0% (95% CI, 13.8–18.5) than girls 8.0% (95% CI, 6.2–10.2; p<0.001), due to 2‐fold higher UTI risk. The prevalence of meningitis in boys was 0.3% (95% CI, 0.1– 0.9) vs. 0.7% (95% CI, 0.2–1.6) in girls and of bacteraemia 1.8% (95% CI, 1.0–2.8) vs. 1.0% (95% CI, 0.4–2.0), respectively.ConclusionsThe total SBI prevalence was 12.6%, and UTI represented the vast majority. The prevalence of bacteraemia and meningitis was low, particularly in the 29–60 days age group, without significant difference between boys and girls.
