Authors: Izumi Takako , Sukhwani Vibhas , Surjan Akhilesh , Shaw Rajib 
Published: July 2020

Purpose
The purpose of this paper is to understand the key challenges, approaches and lessons of the higher educational institutions (HEIs) in the context of COVID-19.

Design/methodology/approach
A survey was conducted to understand the key challenges being faced by the HEIs around the world during the ongoing COVID-19 pandemic. A total of 150 responses were collected from 65 universities, located in 29 countries.

Findings
The results show that 47% of respondents with defined universities believe their institutions lacked a permanent or dedicated emergency management office, and 41% said their HEIs lacked a general business continuity plan for an emergency. In universities with BCPs, 33% of the plans do not cover biological hazards and pandemic risk management, and 60% of the plans did not include conducting any advanced simulation exercises. More than 70% the responded said their instruction, information sharing and decision-making process were timely and open. The major challenges identified were a lack of adequate preparedness for pandemic and of pandemic-specific advanced simulation exercises. The next major challenges were the change in the mode of teaching to online lectures and working from home. Based on these challenges, a set of short- and long-term recommendations were proposed.

Originality/value
This was the first survey in academic institutions in post COVID-19 context. The findings will be useful for preparing for biological and other related hazards.
Towards a framework on the factors conditioning the role of logistics service providers in the provision of inventory financing
Authors: Chakuu Sumeer , Masi Donato , Godsell Janet 
Published: July 2020

PurposeThis paper explores the conditions in which logistics service providers (LSPs) can compete or collaborate with banks in offering inventory financing as a supply chain finance (SCF) service.Design/methodology/approachA multiple case study research methodology was adopted. The case study involved six LSPs across Europe. Data were collected through semi-structured interviews.FindingsThe results highlighted that an attractive credit demand for LSPs consists in suppliers with high amounts of inventory or borrowing needs that go beyond their borrowing capacity from the perspective of a bank. LSPs can respond to this demand when they have three specific capabilities as follows: risk assessment, risk monitoring and organizational capabilities. The offer of inventory financing can be controlled by the LSPs or by the banks. When the LSPs control the offer, they offer different conditions compared to the banks in terms of credit rationing, transaction costs, payment flexibility, tax rate advantage and financial risk management. When the banks control the offer, the LSPs influence the nature of the SCF services only in terms of credit rationing and transaction costs. The LSPs seem to easily develop risk assessment and risk mitigation capabilities, while the organisational capabilities appear to be the most challenging to build, and when absent they create a barrier to the provision of inventory financing.Originality/valueThe value of the paper is twofold. First, the paper provides a comprehensive taxonomy of the factors conditioning the role of the LSPs in the provision of inventory financing as a SCF service. Second, the paper clarifies the link between the factors and the different roles played by the LSPs.
Green service production in healthcare and role of value chain flexibility
Authors: Kumar Pradeep 
Published: July 2020

PurposeThis paper aims to understand the specific role of value chain flexibility (VCF) in the strategies of green service production (GSP) in healthcare. The study explores the key dimensions of VCF and their linkages with the current GSP strategies in healthcare firms.Design/methodology/approachThe study uses an exploratory case study with three representative national-level healthcare firms in India. A multiple case study methodology was utilized to explore the relationships between GSP and VCF.FindingsThe findings of the study suggest that several strategies for GSP require the support of multiple dimensions of VCF. More importantly, the role of each dimension of VCF depends upon the innovativeness of green service design, green procurement and green service practices.Research limitations/implicationsThe study was conducted in the emerging healthcare market of India. Thus, the generalizability of the framework needs to be tested in another context. The study reports the employee's perception, and the patients’ (customers) views were not included.Originality/valueThe study is a first step to understand the theoretical perspectives of the relationships between GSP and VCF by exploring the underlying concepts. Furthermore, the study explicates the dynamics of their interplay in a systematic way and contributes to a framework of GSP and VCF in the healthcare context.

Published: July 2020

Purpose
This study sought to assess the process of initiating a sustainable recycling program at the University of Jordan. It illustrates the potentials of recycling, perceived awareness of recycling by the students and staff, as well as challenges to a sustainable waste recycling program. This study aims to identify the barriers and challenges that face a sustainable waste recycling program at the University of Jordan.

Design/methodology/approach
The study consisted of investigating waste recycling potential on campus, inspecting general environmental awareness toward recycling and running an experimental recycling study on part of the campus. A waste characterization study was conducted to assess the current waste status and recycling extent. A questionnaire survey was carried out to obtain information on the students’ and staffs’ awareness of waste recycling and management on campus. In the experimental recycling study, seventy units of waste segregation bins were distributed on campus. The recycling efficiency was evaluated at two schools; the School of Engineering and the School of Medicine. The administrative support and collaboration while running the recycling program were also observed.

Findings
Overall, waste recycling at the University of Jordan has an appreciable opportunity and potential. A substantial amount of waste can be diverted from going to the landfill. Data showed general positive recycling rates except for plastic. Also, the recycling rates show great potential for enhancing. The recycling at the University of Jordan faces several barriers and obstacles. The greatest barrier was identified as the lack of cooperation of the administrative system on campus. The administrative support for the recycling program was strong only at the initiation of the recycling program. Administrative support has a vital influence on the recycling program. It has the potential of boosting it or bringing it to halt. Future studies should focus on investigating recycling efficiency for the entire campus and focus more on increasing pro-environmental behavior among students and staff in higher education institutions.

Originality/value
The value of this research lies in it being conducted in a large campus university in a developing country. Also, the study used a diagnostic approach that is based on evaluating an environmental sustainability program as it evolves inside a higher education institution. The study illustrates the challenges that face universities in developing countries while adopting green campus initiatives.

A machine learning approach to predict the success of crowdfunding fintech project
Authors: Yeh Jen-Yin , Chen Chi-Hua 
Published: July 2020

PurposeThe crowdfunding market has experienced rapid growth in recent years. However, not all projects are successfully financed because of information asymmetries between the founder and the providers of external finance. This shortfall in funding has made factors that lead to successful fundraising, a great interest to researchers. This study draws on the social capital theory, human capital theory and level of processing (LOP) theory to predict the success of crowdfunding projects.Design/methodology/approachA feature set is extracted and correlations between project success and features are utilized to order the features. The artificial neural network (ANN) is popularly applied to analyze the dependencies of the input variables to improve the accuracy of prediction. However, the problem of overfitting may exist in such neural networks. This study proposes a neural network method based on ensemble machine learning and dropout methods to generate several neural networks for preventing the problem of overfitting. Four machine learning techniques are applied and compared for prediction performance.FindingsThis study shows that the success of crowdfunding projects can be predicted by measuring and analyzing big data of social media activity, human capital of funders and online project presentation. The ensemble neural network method achieves highest accuracy. The investments rose from early projects and another platform by the funder serve as credible indicators for later investors.Practical implicationsThe managerial implication of this study is that the project founders and investors can apply the proposed model to predict the success of crowdfunding projects. This study also identifies the most influential features that affect fundraising outcomes. The project funders can use these features to increase the successful opportunities of crowdfunding project.Originality/valueThis study contributes to apply a new machine learning modeling method to extract features from activity data of crowdfunding platforms and predict crowdfunding project success. In addition, it contributes to the research on the deployment of social capital, human capital and online presentation strategies in a crowdfunding context as well as offers practical implications for project funders and investors.
Why busy leaders may have exhausted followers: a multilevel perspective on supportive leadership
Authors: Stein Maie , Vincent-Höper Sylvie , Gregersen Sabine 
Published: July 2020

PurposeThis study of leaders and followers working in day-care centers aims to use a multilevel perspective on supportive leadership to examine its role in linking workload at the leader level and emotional exhaustion at the follower level. Integrating theoretical work on social support with conservation of resources (COR) theory, leaders' workload is proposed to be positively related to followers' feelings of emotional exhaustion through constraining the enactment of supportive leadership.Design/methodology/approachMultisource survey data from 442 followers and their leaders from 68 teams were collected to test the hypotheses.FindingsMultilevel analyses showed that leader workload was negatively related to followers' perception of supportive leadership, which, in turn, was positively related to followers' levels of emotional exhaustion. Leader workload was indirectly and positively related to follower emotional exhaustion via supportive leadership.Research limitations/implicationsThis study provides initial support for the idea that work contextual factors at the leader level create boundaries for the extent to which leaders may provide support to their followers and draws attention to the accountability of leaders' work contextual factors for followers' well-being.Practical implicationsThe findings suggest that organizations must not focus narrowly on training leaders on how to benefit followers but should also aim to optimize leaders' levels of workload to enable them to act in a supportive manner.Originality/valueBy considering both the receivers (i.e. followers) and providers (i.e. leaders) of support simultaneously, we take a crossover approach to COR theory and acknowledge that work contextual factors at higher organizational levels may spread to employee well-being at lower levels of the organization.
Logistics service quality: where we are and where we go in the context of airline industry
Authors: Thongkruer Peeraya , Wanarat Sawat 
Published: July 2020

Purpose
In practice and in literature, logistics service quality is one of the key concepts in any service industry, including airlines. However, the breadth of content and the inconsistent accounts make comprehensive understanding of service quality elusive, thereby necessitating the conduct of a systematic review of the literature on service quality in the context of airlines. In doing so, this study aims to provide a clear, consistent and current overview of the literature, enabling the advancement of theory and research in service quality.

Design/methodology/approach
In particular, this study presents several aspects of logistics service quality based on the 52 articles reviewed published between 1993 and 2019. Content analysis was used to analyze the data in terms of key attributes of service quality from the selected articles.

Findings
Following an analysis, this study summarizes the antecedents and consequences, along with mediators and moderators, and develops a review framework of service quality.

Research limitations/implications
This study provides a starting point for understanding logistics service quality in a context of airline where choice of perspective (at three different perspectives) and framing of context (where logistics interfaces with marketing function, thereby ensuring a well-functiong synthesis of marketing and service activities in the value chain) are of decisive importance. It also expands an understanding of service quality in marketing field with an integration of logistics function as well as challenging some of the conventional knowledge of the applying logistics in service-based business like the airlines. However, this paper is restricted by several limitations that must be taken into account when applying its findings such as context-specific results,cross-sectional data and recall variables.

Originality/value
This paper provides a clear and consistent concept, as well as a current overview of the literature, which enables advancement in theory and research. It also reveals theoretical underpinnings of the research stream and outlines future research directions. Additionally, it challenges some of the conventional knowledge of the applying logistics on service-based business such as airline which broadens the scope of our thinking and provides a foundation for future study.

Published: July 2020

PurposeThis study aims to examine the impact of balanced agile project management (balanced APM) on firm performance through the mediating role of market orientation and strategic agility of medium and large telecommunication technology providers in Indonesia.Design/methodology/approachResearch data was collected from the executive management of telecommunication technology providers in Indonesia via a questionnaire survey to obtain 150 valid questionnaires for analysis. This study analyzed the overall model fit through confirmatory factor analysis and causal relationships through structural equation modeling.FindingsThe results indicate that market orientation mediates the link between balanced APM and strategic agility and that strategic agility mediates the link between market orientation and firm performance.Research limitations/implicationsThe choice of single telecommunication industry in a single country, Indonesia, provides a limitation on external validity. It is, therefore, suggested to extend the research efforts to other industry sectors in multi-country environments.Originality/valueThis study extends the knowledge about agile project management by embracing balancing control enforcement and tests it empirically. This study also re-conceptualizes strategic agility to embrace business partner switching capability and market orientation to embrace the inter-partner coordination dimension. Finally, the results highlight that agile project management needs to be framed by market orientation to create higher value for customers. However, market orientation alone is not enough and that the organization requires strategic agility to achieve firm performance.
Fungal volatiles influence plant defence against above‐ground and below‐ground herbivory
Authors: Moisan Kay , Aragón Marcela , Gort Gerrit , Dicke Marcel , Cordovez Viviane , Raaijmakers Jos M. , Lucas‐Barbosa Dani 
Published: July 2020

Abstract

Plants have evolved resistance traits that negatively affect attackers, and tolerance traits that sustain plant growth despite herbivore damage. These mechanisms often co‐occur in a mixed‐defence strategy, balancing resistance and tolerance. These plant defences can be enhanced upon interaction with soil micro‐organisms.

Here we investigated the effects of volatiles emitted by soil‐borne fungi on plant defence to insect herbivory, and on plant phenology.

We exposed roots of Brassica rapa plants to volatiles emitted by four soil‐borne fungi. As a proxy of plant resistance, we assessed the performance of Pieris brassicae, a caterpillar feeding on leaves and inflorescences, and of Delia radicum, an insect root herbivore. As a proxy of plant tolerance, we compared growth of volatile‐exposed plants challenged with or without insects. Additionally, we assessed the effects on plant phenology by recording bolting time and by counting the number of buds and flowers.

Plant exposure to fungal volatiles differentially affected plant resistance to above‐ and below‐ground herbivory. Performance of P. brassicae caterpillars differed between the fungal volatile‐exposed plants but was variable between experimental batches. In contrast, the effects of fungal volatiles on D. radicum performance were predominantly negative, indicating an increased plant resistance. Despite root consumption by D. radicum, root dry weight remained unchanged in infested plants compared with uninfested ones, irrespectively of the volatile exposure, suggesting compensation for the tissue loss, sometimes at the cost of undamaged above‐ground tissues. When B. rapa plants were attacked by P. brassicae caterpillars, only exposure to volatiles of some fungi led to compensation for the loss of above‐ground tissues consumed by the caterpillars, which differed between leaves and inflorescences. Furthermore, bolting was accelerated in response to volatiles of some fungi, resulting in more buds and flowers, which suggests a potential enhancement of plant fitness.

Our data show that fungal volatiles can modulate the mixed‐defence strategies of B. rapa plants, balancing plant resistance and tolerance to above‐ and below‐ground herbivory. These effects may be variable and were fungus specific. Ultimately, plant fitness may be enhanced upon root exposure to fungal volatiles.

SummaryPolycyclic aromatic hydrocarbons (PAHs) are among the most persistent xenobiotic compounds, with high toxicity effects. Mycoremediation with halophilic Aspergillus sydowii was used for their removal from a hypersaline medium (1 M NaCl). A. sydowii metabolized PAHs as sole carbon sources, resulting in the removal of up to 90% for both PAHs [benzo [a] pyrene (BaP) and phenanthrene (Phe)] after 10 days. Elimination of Phe and BaP was almost exclusively due to biotransformation and not adsorption by dead mycelium and did not correlate with the activity of lignin modifying enzymes (LME). Transcriptomes of A. sydowii grown on PAHs, or on glucose as control, both at hypersaline conditions, revealed 170 upregulated and 76 downregulated genes. Upregulated genes were related to starvation, cell wall remodelling, degradation and metabolism of xenobiotics, DNA/RNA metabolism, energy generation, signalling and general stress responses. Changes of LME expression levels were not detected, while the chloroperoxidase gene, possibly related to detoxification processes in fungi, was strongly upregulated. We propose that two parallel metabolic pathways (mitochondrial and cytosolic) are involved in degradation and detoxification of PAHs in A. sydowii resulting in intracellular oxidation of PAHs. To the best of our knowledge, this is the most comprehensive transcriptomic analysis on fungal degradation of PAHs.
