•Insights into the impact of COVID-19 outbreak on automobile and airline supply chain is provided.•Integrated time-to-recovery and financial impact analysis, empirical survey and semi-structured ...interviews were used.•Localized supply sources and industry 4.0 technologies identified as significant strategies by automobile industry.•Business continuity by defining operations at the airport and flights perceived significant strategy by airline industry.•Real-time information sharing and cooperation among supply chain stakeholders is critical.
There has been an increased interest among scholars to investigate supply chain resilience (SCRes) in manufacturing and service operations during emerging situations. Grounded in the SCRes theory, this study provides insights into the impact of the COVID-19 outbreak on the automobile and airline supply chain. Both the short and long-term response strategies adopted by the two supply chains are assessed, using a combination of qualitative and quantitative techniques in three distinct phases. In phase one, we use a sequential mixed-method for resilience evaluation, integrating Time-to-Recovery (TTR) and Financial Impact (FI) analysis. In phase two, we conduct an empirical survey involving 145 firms to evaluate the short-term SCRes response strategies. In the third phase, we conduct semi-structured interviews with supply chain executives both from the automobile and airline industries to understand the long-term SCRes response strategies. Our findings indicate that: (i) the automobile industry perceived that the best strategies to mitigate risks related to COVID-19, were to develop localized supply sources and use advanced industry 4.0 (I4.0) technologies. (ii) The airline industry on the other hand, perceived that the immediate need was to get ready for business continuity challenges posed by COVID-19, by defining their operations both at the airports and within the flights. (iii) Importantly, both the sectors perceived Big Data Analytics (BDA) to play a significant role by providing real-time information on various supply chain activities to overcome the challenges posed by COVID-19. (iv) Cooperation among supply chain stakeholders is perceived, as needed to overcome the challenges of the pandemic, and to accelerate the use of digital technologies.

PurposeDrawing on institutional theory, this study investigates the role of individual cultural values on the adoption of socially sustainable supply chain management (socially SSCM) for Chinese ...suppliers facing the normative institutional pressures of guanxi (interpersonal relationships).Design/methodology/approachUsing empirical data collected in three waves from 205 Chinese manufacturers supplying international markets, the proposed theoretical model is tested through partial least squares structural equation modeling (PLS-SEM).FindingsThe results indicate that guanxi has a positive impact on socially SSCM, and this positive effect is strengthened when the individual cultural values of the supplier's representative embody high collectivism and low uncertainty avoidance.Research limitations/implicationsThis study highlights the leading role of guanxi in improving socially SSCM practices due to its normative institutional force. In addition, the findings suggest that future studies should consider individual differences in supply chain partners, which may lead to distinct reactions when facing normative institutional pressures.Practical implicationsThis study suggests international buyers should adopt guanxi management with their Chinese suppliers to encourage them to adopt socially SSCM. In addition, managers should note that the guanxi strategy is more effective when the supplier's representative collectivism is high and uncertainty avoidance is low.Originality/valueThis study contributes to socially SSCM research in emerging economies by unveiling the role of guanxi as a key driver of socially SSCM in the Chinese market and providing empirical evidence of the moderating effect of individual culture on the guanxi normative institutionalization process.
Following the COVID-19 outbreak, a wide range of scholars and practitioners have come to recognize the potential of Additive Manufacturing (AM) technology in building supply chain resilience and ...efficiency. However, it remains unclear how AM technology might be able to simultaneously build supply chain efficiency and resilience, given the often conflicting nature of these qualities. This paper employs an ambidextrous perspective on dynamic capability theory to investigate the potential of AM technology to solve this resilience-efficiency dilemma at the supply chain level. The research design involves a hybrid approach, combining focus groups and multiple case studies, with particular attention paid to the African supply chain context. The findings indicate that AM technology presents the potential to develop ambidextrous dynamic capabilities, leading to the reconciliation of resilience and efficiency at the supply chain level. Some determinants, such as data-driven systems, supply chain collaboration, innovation agility and knowledge are found to be critical to enable the development of those capabilities around AM-enabled manufacturing systems. The study contributes to the preparation of the global supply chain for the post-COVID era, where digital technologies such as AM will be fundamental for both building resilience and efficiency simultaneously. Practitioners in emerging economies may benefit directly from the outcomes of this study. Furthermore, managers and policy-makers in developed countries may be made aware of the significance of using AM technology in emerging countries to enhance the performance of the global supply chain.

The study aims to propose a decision-making framework for prioritising solutions to overcome barriers to omnichannel adoption in logistics. An empirical case study has been carried out to assess the ...practicality and validity of this framework in the actual environment. The decision-making framework embraces an integrated approach comprising of fuzzy Delphi Method (FDM), fuzzy Analytic Hierarchy Process (FAHP) and fuzzy VlseKriterijumska Optimizacija I Kompromisno Resenje (FVIKOR) for capturing human thinking and subjectivity for doing evaluation and prioritisation of solutions. The proposed framework has been evaluated in an Indian apparel firm. The results suggest that the proposed framework can identify and prioritise the solutions of omnichannel adoption in logistics to overcome its barriers. The proposed framework relies on the well-structured knowledge and personal experience of potential experts to consider various fuzzy regions in the decision making. The present framework offers guidelines to practitioners for the successful adoption of omnichannel retailing regarding the identification and prioritisation of solutions to overcome the barriers of omnichannel adoption.

Summary Background Emotional stress is associated with increased risk of cardiovascular disease. We imaged the amygdala, a brain region involved in stress, to determine whether its resting metabolic ...activity predicts risk of subsequent cardiovascular events. Methods Individuals aged 30 years or older without known cardiovascular disease or active cancer disorders, who underwent18 F-fluorodexoyglucose PET/CT at Massachusetts General Hospital (Boston, MA, USA) between Jan 1, 2005, and Dec 31, 2008, were studied longitudinally. Amygdalar activity, bone-marrow activity, and arterial inflammation were assessed with validated methods. In a separate cross-sectional study we analysed the relation between perceived stress, amygdalar activity, arterial inflammation, and C-reactive protein. Image analyses and cardiovascular disease event adjudication were done by mutually blinded researchers. Relations between amygdalar activity and cardiovascular disease events were assessed with Cox models, log-rank tests, and mediation (path) analyses. Findings 293 patients (median age 55 years IQR 45·0–65·5) were included in the longitudinal study, 22 of whom had a cardiovascular disease event during median follow-up of 3·7 years (IQR 2·7–4·8). Amygdalar activity was associated with increased bone-marrow activity ( r =0·47; p<0·0001), arterial inflammation ( r =0·49; p<0·0001), and risk of cardiovascular disease events (standardised hazard ratio 1·59, 95% CI 1·27–1·98; p<0·0001), a finding that remained significant after multivariate adjustments. The association between amygdalar activity and cardiovascular disease events seemed to be mediated by increased bone-marrow activity and arterial inflammation in series. In the separate cross-sectional study of patients who underwent psychometric analysis (n=13), amygdalar activity was significantly associated with arterial inflammation ( r =0·70; p=0·0083). Perceived stress was associated with amygdalar activity ( r =0·56; p=0·0485), arterial inflammation ( r =0·59; p=0·0345), and C-reactive protein ( r =0·83; p=0·0210). Interpretation In this first study to link regional brain activity to subsequent cardiovascular disease, amygdalar activity independently and robustly predicted cardiovascular disease events. Amygdalar activity is involved partly via a path that includes increased bone-marrow activity and arterial inflammation. These findings provide novel insights into the mechanism through which emotional stressors can lead to cardiovascular disease in human beings. Funding None.

This paper aims to evaluate the relationship between academic optimism and sustainability of higher education. The intervening role of extra role behavior and internal branding is also examined. The ...data was collected from higher education institutions via randomly selected sample. A confirmatory factor analysis was carried out to evaluate the model fit and reliability, validity and internal consistency of the measures were evaluated. Further, hierarchical regression analysis was used to test the direct and indirect relationship among the hypothesised constructs. The regression analysis results supported a positive relationship between academic optimism and sustainability of higher education through internal branding and extra role behavior. Internal branding and extra role behavior positively mediated the linkage between academic optimism and sustainability in higher education. The study contributes to the practice as it helps academicians, practitioners, and professionals working in higher education institutions in their decision making.

Psoriasis increases the risk of cardiovascular (CV) disease. Secukinumab, a fully human monoclonal antibody against IL-17A, shows significant efficacy in psoriasis, but effects on CV markers are ...unknown. CARIMA (Evaluation of Cardiovascular Risk Markers in Psoriasis Patients Treated with Secukinumab) was a 52-week, randomized, double-blind, placebo-controlled, exploratory trial in patients with moderate to severe plaque psoriasis without clinical CV disease. Patients were randomly assigned to receive 300 mg or 150 mg secukinumab until week 52 or to receive placebo until week 12 and then 300 mg or 150 mg secukinumab until week 52. The primary outcome was endothelial function measured by flow-mediated dilation (FMD). Baseline FMD was significantly lower in psoriasis patients than healthy volunteers (4.4 ± 3.9% vs. 6.1 ± 3.3%, P = 0.01). At week 12, baseline-adjusted mean FMD was numerically higher in patients receiving secukinumab versus those receiving placebo, but this difference (300-mg group, +1.2%; 150-mg group, +0.76%; P = 0.223 and P = 0.403 by analysis of covariance) did not reach significance. At week 52, FMD increased across groups. FMD was significantly higher than baseline in patients receiving the label dose of 300 mg secukinumab for 52 weeks (+2.1%, 95% confidence interval = 0.8–3.3; P = 0.0022). Other relevant CV markers were unchanged. CARIMA indicates that secukinumab might have a beneficial effect on CV risk by improving the endothelial function of patients with plaque psoriasis.

PurposeAgriculture value chains (AVCs) have experienced unprecedented disruption during the COVID-19 pandemic, with lockdowns and stringent social distancing restrictions making buying and selling ...behaviours complex and uncertain. This study aims provide a theoretical framework describing the stakeholder behaviours that arise in severely disrupted value chains, which give rise to inter-organisational initiatives that impact industry sustainability.Design/methodology/approachA mixed-methods approach is adopted, in which uncertainty theory and relational governance theory and structured interviews with 15 AVC stakeholders underpin the initial conceptual model. The framework is empirically validated via partial least squares structural equation modelling using data from an online survey of 185 AVC stakeholders based in India.FindingsThe findings reveal that buyer and supplier uncertainty created by the COVID-19 lockdowns gives rise to behaviours that encourage stakeholders to engage in relational governance initiatives. Progressive farmers and other AVC stakeholders welcome this improved information sharing, which encourages self-reliance that positively impacts agricultural productivity and sustainability.Practical implicationsThe new framework offers farmers and other stakeholders in developing nations possibilities to sustain their AVCs even in dire circumstances. In India, this also requires an enabling ecosystem to enhance smallholders' marketing power and help them take advantage of recent agricultural reforms.Originality/valueResearch is scarce into the impact of buyer and seller behaviour during extreme supply chain disruptions. This study applies relational governance and uncertainty theories, leading to a proposed risk aversion theory.
Intestinal derived endotoxin and the subsequent endotoxemia can be considered major predisposing factors for diseases such as atherosclerosis, sepsis, obesity and diabetes. Dietary fat has been shown ...to increase postprandial endotoxemia. Therefore, the aim of this study was to assess the effects of different dietary oils on intestinal endotoxin transport and postprandial endotoxemia using swine as a model. We hypothesized that oils rich in saturated fatty acids (SFA) would augment, while oils rich in n-3 polyunsaturated fatty acids (PUFA) would attenuate intestinal endotoxin transport and circulating concentrations.
Postprandial endotoxemia was measured in twenty four pigs following a porridge meal made with either water (Control), fish oil (FO), vegetable oil (VO) or coconut oil (CO). Blood was collected at 0, 1, 2, 3 and 5 hours postprandial and measured for endotoxin. Furthermore, ex vivo ileum endotoxin transport was assessed using modified Ussing chambers and intestines were treated with either no oil or 12.5% (v/v) VO, FO, cod liver oil (CLO), CO or olive oil (OO). Ex vivo mucosal to serosal endotoxin transport permeability (Papp) was then measured by the addition of fluorescent labeled-lipopolysaccharide.
Postprandial serum endotoxin concentrations were increased after a meal rich in saturated fatty acids and decreased with higher n-3 PUFA intake. Compared to the no oil control, fish oil and CLO which are rich in n-3 fatty acids reduced ex vivo endotoxin Papp by 50% (P < 0.05). Contrarily, saturated fatty acids increased the Papp by 60% (P = 0.008). Olive and vegetable oils did not alter intestinal endotoxin Papp.
Overall, these results indicate that saturated and n-3 PUFA differentially regulate intestinal epithelial endotoxin transport. This may be associated with fatty acid regulation of intestinal membrane lipid raft mediated permeability.
