Published: November 2021

Insect juvenile hormones (JHs) are a family of sesquiterpenoid molecules that are secreted into the haemolymph. JHs have multiple roles in insect development, metamorphosis and sexual maturation. A number of pesticides work by chemically mimicking JHs, thus preventing insects from developing and reproducing normally. The haemolymph levels of JH are governed by the rates of its biosynthesis and degradation. One enzyme involved in JH catabolism is JH diol kinase (JHDK), which uses ATP (or GTP) to phosphorylate JH diol to JH diol phosphate, which can be excreted. The X-ray structure of JHDK from the silkworm Bombyx mori has been determined at a resolution of 2.0 Å with an R factor of 19.0% and an R
free of 24.8%. The structure possesses three EF-hand motifs which are occupied by calcium ions. This is in contrast to the recently reported structure of the JHDK-like-2 protein from B. mori (PDB entry 6kth), which possessed only one calcium ion. Since JHDK is known to be inhibited by calcium ions, it is likely that our structure represents the calcium-inhibited form of the enzyme. The electrostatic surface of the protein suggests a binding site for the triphosphate of ATP close to the N-terminal end of the molecule in a cavity between the N- and C-terminal domains. Superposition with a number of calcium-activated photoproteins suggests that there may be parallels between the binding of JH diol to JHDK and the binding of luciferin to aequorin.

Published: November 2021

Purpose
Autism spectrum disorder (ASD) refers to a group of complex neurodevelopmental disorders characterized by repetitive and characteristic patterns of behavior and difficulties with social communication and interaction. Puberty is an important period for teenagers with ASD. The purpose of this study was to investigate the effect of educational program on increasing social skills (SS) and sexual knowledge (SK) in adolescent boys with high-functioning autism (HFA) disorder.

Design/methodology/approach
This study was conducted using a single-subject design. Participants were three boys diagnosed with HFA disorder, selected using purposive sampling. The social skills improvement system scale and the sexual knowledge questionnaire were used to measure SS and SK. The training program consisted of 49 sessions.

Findings
Results showed that, given the comparison of scores before and after the intervention, the training program was effective in improving SS and SK.

Originality/value
With regard to the importance of puberty, training programs for parents and adolescents play an effective role in increasing SS and SK of adolescents with HFA disorder.
Reviewing the place of migrants in disasters: a personal perspective
Authors: Torres Anna M.S. 
Published: November 2021

PurposeThe paper aims to call attention to issues that may be missing or taken for granted in discourses on migrants and disasters by applying the author’s viewpoint to reflect on gaps and potentials for disaster risk reduction.Design/methodology/approachThe author discusses key issues based on reflective engagement with selected secondary documentation in the form of grey and scholarly literature. Personal perspectives are engaged to develop arguments on intersections that are relevant to the migrant situation in different frameworks in disaster studies.FindingsWhile migrants are considered significant stakeholders in key global agreements on disaster and migration, encounters with disaster literature from a more localised level reveal how references to the migrant sector can be omitted or racialised. This gap can be filled by searching for documentation of migrant strengths and vulnerabilities. However, further reflection demonstrates how adopting broader perspectives can reveal these strengths and vulnerabilities as part of more appropriate and sustainable disaster risk reduction strategies. The paper also shows how such reflections can be led by insights from migrants themselves, not as subjects to be managed but as agents of their own change.Originality/valueThe paper is distinctive because it shows aspects of migrant strengths and disadvantages from a personal viewpoint. It amplifies less-heard perspectives on a conceptual level as well as in actual practice.
South African Airways – born again?
Authors: Ward Michael 
Published: November 2021

Case overview
This case focuses on the business rescue of South African Airlines. SAA, four times rated the best airline in Africa (SAA, 2019), was already insolvent when in early 2020 COVID-19 decimated the world. The state-owned airline, which had last made profits in 2011, continued to lose millions of passengers to competitors over the next decade and, despite bailouts of more than R40bn, entered Business Rescue in December 2019, still owing creditors more than R26bn. To the surprise of many, Public Enterprises minister Pravin Gordhan was determined to rescue the airline. In May 2021, the business rescue practitioners handed SAA back to the interim board and Thomas Kgokolo (CA) (MBA) was appointed interim CEO. In June 2021, Gordhan announced a “born again” SAA, “almost ready to take off” and promised no more bailouts. But, with several billion rand outstanding to complete the rescue plan, a grounded fleet, unresolved labour problems, an critical but unnamed “strategic-equity partner” and a largely unvaccinated country entering its third COVID wave – what were the chances?

Expected learning outcomes
Within the framework of a country desperately in need of jobs and short of capital, the case raises questions about ethics, accountability, responsibility, management, economics and strategy. Should retrenched workers in airlines feel the consequences of their unfortunate career choices? Ought government’s bail-out already failed industries? Should governments run airlines? What sources of funds are available? Have all the necessary requirements for “restructuring” to succeed been satisfied?

Authors: Nishan Fathmath , Mohamed Ahmed 
Published: November 2021

PurposeThe purpose of this study is to explore educational policy directions in the Maldives to continue learning in public schools during the coronavirus disease 2019 (COVID-19) pandemic and identify policy changes that could improve the preparedness of the schools for future pandemics.Design/methodology/approachThis qualitative study is descriptive in nature with an analytical methodology of document and interview data analysis. The purposively selected participants for the interviews included senior officials of the Ministry of Education, school leaders and teachers of public schools in the Maldives.FindingsThis study identified significant policy changes for public schools in the Maldives during the COVID-19 pandemic. These were early response and timely policy directions to continue education during the COVID-19 pandemic. Another finding was the effective change communication of the educational policies for its implementation. Following the policy changes, the teachers were trained for online teaching, hence increasing their competency in information and communications technology. As a result, this led to resilient teachers who were determined to provide education through the challenging times of the pandemic. Hence, it is evident that the school system of the Maldives will emerge stronger beyond COVID-19.Originality/valueThe education policy changes for public schools in the Maldives during the global COVID-19 pandemic have merits for education practices beyond the pandemic.

Dual images in reversible data hiding with adaptive color space variation using wavelet transforms
Authors: Upendra Raju K. , Amutha Prabha N. 
Published: November 2021

PurposeSteganography is a data hiding technique used in the data security. while transmission of data through channel, no guarantee that the data is transmitted safely or not. Variety of data security techniques exists such as patch work, low bit rate data hiding, lossy compression etc. This paper aims to increase the security and robustness.Design/methodology/approachThis paper describes, an approach for multiple images steganography that is oriented on the combination of lifting wavelet transform (LWT) and discrete cosine transform (DCT). Here, we have one cover image and two secret images. The cover image is applied with one of the different noises like Gaussian, Salt & Pepper, Poisson, and speckle noises and converted into different color spaces of YCbCr, HSV, and Lab.FindingsDue to the vast development of Internet access and multimedia technology, it becomes very simple to hack and trace secret information. Using this steganography process in reversible data hiding (RDH) helps to prevent secret information.Originality/valueWe can divide the color space converted image into four sub-bands of images by using lifting wavelet transform. By selecting lower bands, the discrete cosine transform is computed for hiding two secret images into the cover image and again one of the transformed secret images is converted by using Arnold transform to get the encrypted/embedded/encoded image. To extract the Stego image, we can apply the revertible operation. For comparing the results, we can calculate PSNR, SSIM, and MSE values by applying the same process for all color spaces of YCbCr, HSV, and Lab. The experimental results give better performance when compared to all other spaces.
How does bank liquidity creation affect non-performing loans in the MENA region?
Authors: Alaoui Mdaghri Anas 
Published: November 2021

PurposeThe study aims to empirically examine the effect of bank liquidity creation on non-performing loans (NPLs) in the Middle East and North Africa (MENA) region.Design/methodology/approachBerger and Bouwman's (2009) three-step methodology was employed to calculate the level of liquidity creation of a selected sample of 111 commercial banks in ten MENA countries from 2010–2017. Next, the two-step system generalized method of moments (GMM) estimator was used to investigate the linkage between bank liquidity creation and NPLs.FindingsThe results demonstrated a significant negative effect of bank liquidity creation on NPLs in the short and long term, implying that liquidity creation through both on- and off-balance sheet activities decreases NPLs. These findings accord with the “economic-enhancing” view. Furthermore, regression analysis investigated whether this relationship remained similar for Islamic and conventional banks. The results showed that liquidity creation diminishes Islamic and conventional bank NPLs.Research limitations/implicationsThe empirical findings raise several significant policy implications. Bank liquidity creation may decrease rather than increase NPLs, although the process of liquidity creation is viewed as risky by rendering banks more illiquid. Therefore, policy-makers should encourage bank liquidity creation to stimulate the economy. In a robust economy, borrowers are more likely to repay their debts, consequently diminishing banks' NPLs.Originality/valueTo the best of the author's knowledge, the current study is the first to provide empirical evidence on the effect of bank liquidity creation on NPLs in MENA countries.
Sustainable orientation and purchasing: what about a remanufactured component?
Authors: Tondolo Vilmar Antonio Gonçalves , Paiva Ely Laureano , Tondolo Rosana da Rosa Portella , Santos Juliana Bonomi 
Published: November 2021

PurposeThis paper aims to investigate how the sustainable orientation (SO) of companies and the strategic importance of components strategic importance may affect the decision to purchase remanufactured items.Design/methodology/approachThis study employed a 2 × 2 full-factorial (combining between and within-subjects), scenario-based, role-playing experiment. Subjects in the study were US managers familiar with purchasing/supply chain topics. The hypotheses were tested using linear regression models.FindingsThe findings suggest that before becoming aware of any social benefits, a company's SO directly affects purchasing decisions, especially when the component is strategic. Perceptional aspects also play a significant role.Research limitations/implicationsThis study may help managers develop strategies for adopting the use of remanufactured components. New studies can benefit from the findings by focusing on how awareness of social benefits may increase the likelihood of using remanufactured components.Originality/valueThe findings suggest that before becoming aware of any social benefits, a company's SO directly affects purchasing decisions, especially when the component is strategic. Perceptional aspects also play a significant role.
Lessons from the fastest Brazilian unicorn
Authors: Damasceno André Luiz Tavares , Morini Cristiano , Pannellini Gean Lucas 
Published: November 2021

PurposeThe purpose of this paper is to analyze the process of why a Brazilian digital startup company reached unicorn status the fastest.Design/methodology/approachAfter the literature review, the authors conducted the questionnaire containing 13 questions used in 18 in-depth interviews conducted in the case study. Saturation point combined with the independent and in-depth analysis of the researchers is used to achieve internal and external validity. The primary data collected underwent an analytical approach, followed by a resource-based view (RBV). RBV does not deal with time. There is a gap in the literature and an opportunity here: to analyze the fastest company to become a unicorn under the RBV lens.FindingsThe case reveals that value can be found in traditional sectors, as is the case of the real estate sector. This is a case of a company in the direct home-buying space.Practical implicationsThe contribution of this paper is both practical, with the seven lessons, and theoretical. Resources allocated to a specific context in a specific geographic region shift the attention away from the absolute value of resources to the timing of aggregating them. Thus, the contribution accounting for time is new to the RBV.Originality/valueThe originality lies in the analysis of the dynamics of digital businesses with exponential growth.
Drivers of integration of green into supplier selections: a systematic literature review
Authors: Ograh Tonny , Ayarkwa Joshua , Osei-Asibey Dickson , Acheampong Alex , Amoah Peter 
Published: November 2021

PurposeThis paper aims to provide a systematic review of extant literature on supplier selection by identifying drivers of integration of Environmental Sustainability (ES) into supplier selection, with the aim of classifying them under broad categories for the development of a framework showing the interrelationships among them.Design/methodology/approachA search was ran for selected keyword themes using three powerful and rigorous search engines: Scopus, Google Scholar and Science Direct, to identify relevant articles from 12 peer-reviewed journals. These were desk reviewed through manual filtering to select drivers of integration of ES into supplier selection.FindingsThirty-one drivers identified from 41 relevant articles as propelling integration of ES into supplier selection were then classified into five categories: strong policy direction, high level of commitment, desire for high reputation, robust technology and availability of green products. This yielded a framework showing the interconnectedness among the drivers.Research limitations/implicationsThe study contributes to the body of knowledge by developing a classification of drivers of integration of ES into supplier selection. The interconnectedness brought to the fore a more subtle appreciation of the drivers of green integration, which could help expand current knowledge outside the narrow scope of isolated drivers. This study provides detailed analyses of drivers of green integration into supplier selection.Originality/valueThis paper provides a comprehensive review of drivers of integrating green into supplier selection, which is lacking in the body of knowledge on ES.
Scientific literacy, librarians and information literacy in the post-truth era
Authors: Frederick Donna Ellen 
Published: November 2021

Purpose
The purpose of this paper is to challenge librarians to reconceptualize their professional self-image and practice so that it more closely aligns with the information science discipline that is part of the Masters of Library and Information Science degree.

Design/methodology/approach
This column is primarily theoretical and philosophical but also draws on the author’s observations of trends and patterns in both librarianship and changes in information needs in recent years.

Findings
Urgent, high-cost information needs created by COVID-19 and climate change coexist in a reality where technological change has made traditional librarian roles and functions less critical. By developing their information science skills and strengthening their professional identity as information scientists, librarians have the opportunity to address the urgent information needs of the day while remaining highly relevant professionals.

Practical implications
Librarians will need to strengthen their science-related skills and knowledge and begin to promote themselves as information scientists.

Social implications
Librarians are in a position to make a meaningful contribution to two of the most pressing challenges of the day, climate change and dealing with the COVID-19 pandemic.

Originality/value
This paper is relevant to all librarians at any stage of their career. It will help them to reflect on both their skillset and career path and to make any needed adjustments so that they can remain relevant in a volatile and demanding information environment.
Optimising truck arrival management and number of service gates at container terminals
Authors: Minh Chu Cong , Noi Nguyen Van 
Published: November 2021

PurposeTruck appointment systems have been applied in critical container ports in the United States due to their potential to improve handling operations. This paper aims to develop a truck appointment system to optimise the total cost experiencing at the entrance of container terminals by managing truck arrivals and the number of service gates satisfying a given level of service.Design/methodology/approachThe approximation of Mt/G/nt queuing model is applied and integrated into a cost optimisation model to identify (1) the number of arrival trucks allowed at each time slot and (2) the number of service gates operating at each time slot that ensure the average waiting time is less than a designated time threshold. The optimisation model is solved by the Genetic Algorithm and tested with a case study. Its effectiveness is identified by comparing the model's outcomes with observed data and other recent studies.FindingsThe results indicate that the developed truck appointment system can provide more than threefold and twofold reductions of the total cost experiencing at the terminal entrance compared to the actual data and results from previous research, respectively.Originality/valueThe proposed approach provides applicably coordinated truck plans and operating service gates efficiently to decrease congestion, emission and expenses.
The role of organizational and social factors for information security in a nuclear power industry
Authors: Gyllensten Kristina , Torner Marianne 
Published: November 2021

PurposeThe aim of this study was to explore the organizational and social prerequisites for employees' participative and rule-compliant information security behaviour in Swedish nuclear power production and its related industry. These industries are high-risk activities that must be meticulously secured. Protecting the information security in the related organizations is an essential aspect of this.Design/methodology/approachIndividual in-depth interviews were conducted with 24 employees in two organizations within the nuclear power industry in Sweden.FindingsWe found that prerequisites for employees' participative and rule-compliant information security behaviour could be categorized into structural, social and individual aspects. Structural aspects included well-adapted rules, knowledge support and resources. Social aspects included a supportive organizational culture, collaboration and adequate resources, and individual aspects included individual responsibility.Originality/valueThe qualitative approach of the study provided comprehensive descriptions of the identified preconditions. The results may thus enable organizations to better promote conditions important for information security in a high-risk industry.
