Authors: Pattnaik Subash Chandra , Sahoo Rashmita 
Published: May 2021

PurposeThis study aims to examine the relationship between transformational leadership, organizational citizenship behaviour (OCB), job autonomy and supportive management with job autonomy and supportive management as mediating variables.Design/methodology/approachPrimary data was collected through a survey of employees from business organizations in India. Data from 422 valid responses were analysed using structural equation modelling. Confirmatory factor analysis was run for assessment of the measurement model. Then the mediation effects of job autonomy and supportive management were tested for the hypothesized model.FindingsFindings of the analyses indicate that transformational leadership directly and positively influences OCB, job autonomy and supportive management. Job autonomy and supportive management directly and positively influence OCB and mediate the relationship between transformational leadership and OCB partially.Originality/valueContribution of the study comes from advancement of literature by supporting the mediating effects of job autonomy and supportive management in the relationship between transformational leadership and OCB. Thus, the study provides a basis for the mechanism of how transformational leadership is related to OCB.
The geopolitics of COVID-19: US-China rivalry and the imminent Kindleberger trap
Authors: Bahi Riham 
Published: May 2021

Purpose
The spread of COVID-19 is not just a health crisis. The pandemic has taken a geopolitical dimension. The health crisis amplified the competitive dynamics between the USA and China, affected the provision of global public goods and injected instability into the global order. In line with the geopolitical zero-sum thinking, both the USA and China have sought to capitalize on the crisis to boost their international profile. Instead of working together to mitigate the health and economic impacts of COVID-19, the two powers fear that the other will exploit the current situation to accrue political, economic or military gains that will give it an edge after the pandemic subsides. The spread of COVID-19 has set off a “battle of narratives,” in which China and the USA are accusing each other of failing to rise to the challenge. The world seems to be falling into a “Kindleberger Trap,” in which the established power is unable to lead while the rising power is unwilling to assume responsibility. The COVID-19 crisis is occurring amid the collapse of global cooperation. The USA, the traditional leader of international collective efforts in times of crisis, has abandoned its role entirely. The lack of leadership at the global level during an international crisis may cause the breakdown of the international order.

Design/methodology/approach
This paper examines the US-China competitive dynamics through the lens of the work of Charles Kindleberger, which both liberals and realists regard as foundational when examining the dynamics of global crisis management. This paper also uses the meta-geopolitics framework to determine the ability of both China and the USA to respond to the current COVID-19 crisis and its implications for their power and standing in the international system.

Findings
This paper concludes that the only way to escape the Kindleberger trap is “to embed Sino-American relations in multilateralism.”

Originality/value
As rivals, both the USA and China are seeking to capitalize on the crisis to boost their international profile. This paper probes how China and the USA navigated the ongoing COVID-19 crisis to determine whether or not they are currently in a “Kindleberger Trap,” using elements of the meta-geopolitics framework of analysis, namely, health issues, domestic politics, economics, science and international diplomacy. Using the meta-geopolitics framework will help us determine the ability of both China and the USA to respond to the current COVID-19 crisis and the implications of that on their power and standing in the international system.
Who cares? Supply chain managers’ perceptions regarding cyber supply chain risk management in the digital transformation era
Authors: Creazza Alessandro , Colicchia Claudia , Spiezia Salvatore , Dallari Fabrizio 
Published: May 2021

Purpose
The purpose of this paper is to explore the perceptions of supply chain managers regarding the elements that make up cyber supply chain risk management (CSCRM) and the related level of alignment, to understand how organizations can deploy a CSCRM strategy that goes beyond the technical, internal functioning of single companies and moves beyond the dyad, to create a better alignment that can ultimately lead to improved cyber supply chain resilience.

Design/methodology/approach
An exploratory survey in the fast-moving consumer goods (FMCG) industry involving over 100 organizations in Italy was conducted. Results were analysed through one-way analysis of variance, to appraise the differences in the perceptions of the various actors of the FMCG supply chain (Manufacturers, Logistics Service Providers, Retailers).

Findings
While a certain degree of alignment of the perceptions across the FMCG supply chain exists, the study found that Logistics Service Providers can play a crucial role as orchestrators of the CSCRM process towards a more “supply chain-oriented” response to cyber threats and risk events. The research also highlights the necessity to see people as key elements for improving cyber resilience in the supply chain.

Research limitations/implications
Through a vertical analysis of a supply chain, the study extends the existing theory on CSCRM, which contains isolated case studies. It also contributes to extending the current theory with the proposal of the paradigm of Logistics Service Providers as orchestrators of the CSCRM process. The study combines different classifications of CSCRM initiatives and embraces theories external to the supply chain literature.

Practical implications
Through the empirical analysis, this study helps practitioners in streamlining the design of cyber security strategies and actions that span across the supply chain for better alignment. This could mean more coordination of efforts and more targeted/accurate investments in CSCRM initiatives. The study invites practitioners to ponder the perceived relevance of the human factor as a source of risk and the perceived importance of countermeasures aimed at mitigating risk events stemming from that source.

Originality/value
By focusing on an entire supply chain, this is one of the first studies on CSCRM that goes beyond the dyad. Its originality also lies in its use of the investigations of perceptions along the supply chain as pillars for the alignment of CSCRM strategies and mitigation initiatives. This original perspective allows for discovering the role of Logistics Service Providers in driving the alignment of the efforts towards better outcomes of the CSCRM process.
Combined effect of temperature and water stress on seed germination of four Leptocereus spp. (Cactaceae) from Cuban dry forests

Published: May 2021

AbstractCactus seeds have developed adaptations to survive with high temperatures and low soil moisture in their habitats. We studied the effect of the combination of four water potentials (0, −0.2, −0.4 and −0.6 MPa) and two temperatures (25°C and 35°C) on germination and seedling mass of four endemic Leptocereus species from Cuba. There were two semi‐arid coast species (L. arboreus and L. santamarinae) and two species inhabiting dry inland karstic hills (L. ekmanii and L. scopulophilus). We hypothesized that: (a) a decrease in water potential and an increase in temperature would result in low and slow germination, as well as in low seedling mass, and (b) ungerminated cactus seeds after exposure to combined water and temperature stress would have a high recovery capacity. The minimum time required for the seeds to start germination (Tmin), mean germination time (MGT) and germinability were evaluated. In addition, seed mass, the recovery after treatments of non‐germinated seeds, and the seedling fresh mass obtained under different treatments were compared between species. In general, germination was only obtained at 25°C and germinability and seedling mass were drastically affected by the reduction from 0 MPa to −0.2 MPa. Seeds showed thermoinhibition at 35°C at all water potentials. There was a tendency to increase the MGT with decreasing water potential in three species. Low seed recovery occurred at all combined treatments for three species. If the predictions of increased temperature and decreased rainfall for the Caribbean region occur, a reduction in the germination of the Leptocereus species studied is expected.
The role of hopanoids in fortifying rhizobia against a changing climate

Published: May 2021

SummaryBacteria are a globally sustainable source of fixed nitrogen, which is essential for life and crucial for modern agriculture. Many nitrogen‐fixing bacteria are agriculturally important, including bacteria known as rhizobia that participate in growth‐promoting symbioses with legume plants throughout the world. To be effective symbionts, rhizobia must overcome multiple environmental challenges: from surviving in the soil, to transitioning to the plant environment, to maintaining high metabolic activity within root nodules. Climate change threatens to exacerbate these challenges, especially through fluctuations in soil water potential. Understanding how rhizobia cope with environmental stress is crucial for maintaining agricultural yields in the coming century. The bacterial outer membrane is the first line of defence against physical and chemical environmental stresses, and lipids play a crucial role in determining the robustness of the outer membrane. In particular, structural remodelling of lipid A and sterol‐analogues known as hopanoids are instrumental in stress acclimation. Here, we discuss how the unique outer membrane lipid composition of rhizobia may underpin their resilience in the face of increasing osmotic stress expected due to climate change, illustrating the importance of studying microbial membranes and highlighting potential avenues towards more sustainable soil additives.

SummaryRice sheath blight caused by Rhizoctonia solani is the major disease of rice that seriously threatens food security worldwide. Efficient and eco‐friendly biological approaches are urgently needed since no resistant cultivars are available. In this study, fallow and paddy soils were initially subjected to microbiome analyses, and the results showed that Talaromyces spp. were significantly more abundant in the paddy soil, while Trichoderma spp. were more abundant in the fallow soil, suggesting that Talaromyces spp. could live and survive better in the paddy soil. Five Talaromyces isolates, namely, TF‐04, TF‐03, TF‐02, TF‐01 and TA‐02, were isolated from the paddy soil using sclerotia of R. solani as baits and were further evaluated for their activity against rice sheath blight. These isolates efficiently parasitized the hyphae and rotted the sclerotia even at higher water contents in the sterilized sand and the soil. Isolate TF‐04 significantly promoted rice growth, reduced the severity of rice sheath blight and increased the rice yield under outdoor conditions. Defence‐related genes were upregulated and enzyme activities were enhanced in rice treated with isolate TF‐04. Our research supplies a microbiome‐guided approach to screen biological control agents and provides Talaromyces isolates to biologically control rice sheath blight.
Who knows best? Health risks and digital media engagement in Discourses relating to human papillomavirus vaccination
Authors: Nordtug Maja 
Published: May 2021

AbstractIn Denmark, parents have needed to deal with inconsistent presentations of risk regarding the human papillomavirus (HPV) vaccination. This has complicated the parents' task of making a decision about having their daughters vaccinated. In this article, I analyse how Danish parents engage with digital media when making this decision. The results are based on interviews with 18 Danish parents of girls aged 10–13 years old. In my analysis of the interviews, I found that parents align with one of two Discourses when engaging with digital media in relation to HPV vaccination: one centralised and one decentralised. In the centralised Discourse, parents leave it up to other actors such as health authorities to manage the risks of vaccination, thus limiting the experienced need to engage with digital media; in the decentralised Discourse, however, parents themselves assess potential risks, thereby increasing the need to engage with digital media. As a result, I discuss why some parents can consider it necessary to struggle to engage in literacies when making decisions about complex health topics, even when there are clear government recommendations.
Blending mindfulness practices and character strengths increases employee well‐being: A second‐order meta‐analysis and a follow‐up field experiment

Published: May 2021

AbstractThis study summarises the existing literature on Mindfulness‐Based Interventions (MBIs) and their effect on employee well‐being criteria and extends it by testing MBIs against a Mindfulness‐Strengths‐Based Intervention (MSBI). Given that extant MBIs focus on restoring well‐being, our first hypothesis was that MBIs would perform better on reducing negative emotional states than on promoting well‐being. To test our first hypothesis, we conducted a second‐order meta‐analysis, which summarised 13 first‐order meta‐analyses (k = 311). MBIs had stronger effects on reducing negative emotions (g = −0.74) than on increasing well‐being (g = 0.58). Then, we conducted a follow‐up field experiment, comparing how an MSBI performed against an MBI on employee well‐being criteria. An MSBI combines mindful meditation, mindful living and Character‐Strengths‐Based Interventions. Our second hypothesis was that an MSBI would outperform an MBI on increasing employee well‐being criteria. During an MSBI, participants (a) attain a conscious state of mindful awareness, and (b) direct their attention towards the discovery and habitual exercise of their character strengths. To test our second hypothesis, we randomly assigned employees of a small Spanish healthcare organisation to either an MSBI or an MBI intervention group. We measured employee well‐being, before and after the intervention, using two well‐established measures of hedonic and eudaimonic well‐being. Our results show that both interventions were successful and had a large effect on both well‐being criteria. Further, as predicted, the MSBI group reported higher absolute scores of well‐being than the MBI group. Implications for theory and practice are discussed, and detailed appendices for practitioners are provided.

Authors: Testori Alberto , Ferraroli Giorgio , De Carlo Camilla , Bossi Paola , Alloisio Marco , Mangiameli Giuseppe 
Published: May 2021

AbstractSmall cell lung cancer (SCLC) is an aggressive malignancy with a poor prognosis that accounts for 10% of all cases of clinical lung cancer. Due to its high growth fraction and rapid doubling time it is usually diagnosed as extensive local or metastatic disease in 60%–70% of cases. Combined small cell lung cancer (C‐SCLC) is a relatively rare subtype of SCLC and is defined as SCLC combined with any elements of non‐small cell lung cancer (NSCLC). Clinical presentation of SCLC as an isolated pedunculated endotracheal lesion is an especially rare occurrence. Here, we report for the first time the occurrence of a C‐SCLC as a polypoid tumor of the trachea diagnosed in an 80‐year‐old woman admitted to the emergency department with a principal complaint of cough and wheezing.

AbstractBackgroundIt has recently been suggested that concomitant medication may affect the clinical outcome of patients treated with immune checkpoint inhibitors (ICIs). However, only a few studies on the impact of concomitant medication on immune‐related adverse events (irAEs) have previously been reported. Here, we aimed to determine the impact of concomitant medication on the efficacy and safety of ICIs.MethodsWe retrospectively analyzed the data of 300 patients treated with nivolumab or pembrolizumab for advanced non‐small cell lung cancer (NSCLC) between January 2016 and July 2018. Multivariate logistic regression analysis was used to assess the effect of concomitant medication on treatment response or irAEs. A multivariate Cox proportional hazards model was used to evaluate concomitant medication‐related factors associated with time‐to‐treatment failure or overall survival (OS).ResultsA total of 70 patients responded to treatment and 137 experienced irAEs. The response rate and incidence of irAEs in patients treated with ICIs were not significantly associated with concomitant medication. Multivariate analysis showed that the use of opioids was an independent factor (time‐to‐treatment failure: hazard ratio 1.39, p = 0.021, OS: hazard ratio 1.54, p = 0.007).ConclusionsThe efficacy and safety of nivolumab or pembrolizumab in the treatment of patients with advanced NSCLC were not significantly influenced by concomitant medication. However, opioid usage might be associated with shorter OS in patients treated with these ICIs. Further mechanistic investigations should explore whether these associations are purely prognostic or contribute to ICI resistance.

Abstract

Many organisms live in environments in which temperatures differ substantially from those measured by standard weather stations. The last decade has witnessed a paradigm shift in efforts to quantify these differences and to understand their ecological, functional and evolutionary implications. This renewed interest in microclimate ecology has been accompanied by the development of various compact temperature sensors and radiation shields. However, it is clear that there are many pitfalls when measuring temperature using these devices.

Here we address the problem of measuring temperatures in these microenvironments accurately. We first discuss the theory of measuring surface, ground and air temperatures with reference to energy fluxes and how these are modified by material, reflective properties and size of the device. We highlight the particular difficulties associated with measuring air temperature. We then report on the results of a series of experiments in which air temperatures recorded by various commonly used microclimate temperature loggers are compared to those obtained using research‐grade instruments and synoptic weather stations.

While accurate measurements of surface and ground temperatures and air temperatures at night and in shaded environments can be relatively easily obtained, we show substantial errors are to be expected when measuring air temperatures in environments exposed to sunlight. Most standard sensors yield large errors, which can reach 25°C due to radiative fluxes operating on the thermometer. This problem cannot be wholly overcome by shielding the thermometer from sunlight, as the shield itself will influence both the temperatures being measured and the accuracy of measurement.

We demonstrate that reasonably accurate estimates of air temperature can be obtained with low‐cost and unshielded ultrafine‐wire thermocouples that possess low thermal emissivity and a highly reflective surface. As the processes that create microclimatic temperature variation are the same as those that cause errors, other logger types should be used with care, and generally avoided in environments exposed to sunlight and close to the ground where wind speeds are lower. We urge researchers interested in microclimates and their effects to pay greater heed to the physics of heat exchange when attempting to measure microclimate temperatures and to understand the trade‐offs that exist in doing so.

Abstract

Quantitative evaluations to optimize complexity have become standard for avoiding overfitting of ecological niche models (ENMs) that estimate species’ potential geographic distributions. ENMeval was the first R package to make such evaluations (often termed model tuning) widely accessible for the Maxent algorithm. It also provided multiple methods for partitioning occurrence data and reported various performance metrics.

Requests by users, recent developments in the field, and needs for software compatibility led to a major redesign and expansion. We additionally conducted a literature review to investigate trends in ENMeval use (2015–2019).

ENMeval 2.0 has a new object‐oriented structure for adding other algorithms, enables customizing algorithmic settings and performance metrics, generates extensive metadata, implements a null‐model approach to quantify significance and effect sizes, and includes features to increase the breadth of analyses and visualizations. In our literature review, we found insufficient reporting of model performance and parameterization, heavy reliance on model selection with AICc and low utilization of spatial cross‐validation; we explain how ENMeval 2.0 can help address these issues.

This redesigned and expanded version can promote progress in the field and improve the information available for decision‐making.
