Evolving a bi-objective optimization model for an after sales supply chain in presence of information asymmetry and service level requirement
Authors: Goswami Mohit , Daultani Yash , Tripathi Atul 
Published: April 2021

PurposeOptimization of resources related to man, money, manpower and those related to organization is critical in context of after-sales supply chains. Many times, organizational objectives in terms of resource optimization and providing superior customer experience might be conflicting, however.Design/methodology/approachOne such instance is when customers expect near 100% service level in which case the organizational costs to meet such high service level goes up significantly. To this end, in this research a novel bi-objective optimization model has been evolved for a typical after-sales service supply chain network constituted of the manufacturer, the retailer and the customer. The first objective function pertains to maximization of the manufacturer's and the retailer's profit. The second objective function is related to the minimization of tardiness of order fulfilment (by the retailer) for the customer.FindingsEmploying a small problem instance, the authors generate a number of findings related to service level and information asymmetry. In particular, the authors observe that achieving best possible manufacturer-retailer profit and at the same time 100% service level is a mathematical impossibility. Furthermore, reducing information asymmetry between the customer and the retailer (as opposed to reducing information asymmetry between the retailer and the manufacturer) actually yields higher profits for the manufacturer-retailer pair.Originality/valueThis research describes the mathematical structure of a three-tier after-sales supply chain wherein information quality and service level requirements are key constraints. Furthermore, the study evolves the bi-objective optimization model as a formulation that can drive the operational decisions of manufacturers and retailers who are part of such after-sales service supply chains.
A proposal of recommendation function for element fill-in-Blank problems in java programming learning assistant system
Authors: Wint Su Sandy , Funabiki Nobuo 
Published: April 2021

PurposeTo advance Java programming educations, the authors have developed a Web-based Java programming learning assistant system (JPLAS). It offers the element fill-in-blank problem (EFP) for novice students to study Java grammar and basic programming skills by filling in the missing elements in a source code. An EFP instance can be generated by selecting an appropriate code, and applying the blank element selection algorithm. As it is expected to cover broad grammar topics, a number of EFP instances have been generated. This paper aims to propose a recommendation function to guide a student solving the proper EFP instances among them.Design/methodology/approachThis function considers the difficulty level of the EFP instance and the grammar topics that have been correctly answered by the student, and is implemented at the offline answering function of JPLAS using JavaScript so that students can use it even without the Internet connections.FindingsTo evaluate the effectiveness of the proposal, 85 EFP instances are prepared to cover various grammar topics, and are assigned to a total of 92 students in two universities in Myanmar and Indonesia to solve them using the recommendation function. Their solution results confirmed the effectiveness of the proposal.Originality/valueThe concept of the difficulty level for an EFP instance is newly defined for the proper recommendation, and the accuracy in terms of the average numbers of answer submission times among the students is verified.
The nexus between financial literacy and entrepreneurial success among young entrepreneurs from a low-income community in Cape Town: a mixed-method analysis
Authors: Munyuki Tinashe , Jonah Coretta Maame Panyin 
Published: April 2021

PurposeThis paper aims to explore the association between financial literacy and entrepreneurial success among young entrepreneurs within an economically disadvantaged community in Cape Town, South Africa.Design/methodology/approachThe mixed-method approach was adopted for the study. In-depth interviews were used in collecting the qualitative data while structured interviews using questionnaires were administered in collecting the quantitative data. The participants for the study were strictly young entrepreneurs.FindingsThe study found that entrepreneurs understood the concept of financial literacy and this was corroborated by their financial literacy average score of 59.03, which is above the national financial literacy average score of 54.00. The study further revealed that a positive association exists between financial literacy and entrepreneurial success. Hence, high levels of financial literacy result in increased business success.Research limitations/implicationsThe sample size of the study was relatively small, for which reason, a mixed-method approach was adopted to strengthen the research findings. The research also considered only one disadvantaged community in South Africa (Khayelitsha).Originality/valueTo the best of the knowledge, the influences of financial literacy on the success of small and medium enterprises (SMEs) among young entrepreneurs have not been well-explored in economically disadvantaged areas within the South African context. As a result, this study sheds light by assessing the level of financial literacy among young entrepreneurs in economically disadvantaged communities and by determining the relationship between financial literacy and entrepreneurial success. The study further provides recommendations on policy-making to ensure that through successful entrepreneurship, developmental challenges such as unemployment can be reduced.
Multi-criteria decision-making framework for selecting sustainable private partners for housing projects
Authors: Abdullah Abdullah Khalid , Alshibani Adel 
Published: April 2021

Purpose
This paper aims to develop a framework for the selection of private partners in the housing industry of Saudi Arabia under the scheme of the partnership between the public and private sectors.

Design/methodology/approach
By investigating criteria from a comprehensive literature review and experts input through surveys, developing further surveys incorporating decision-making methods: analytic hierarchy process (AHP) and multi-attribute utility theory (MAUT) to construct a framework for selection based on weightages and utilities.

Findings
The results identified criteria categorized under four categories: financial (C1), technical (C2), managerial (C3) and safety/environment (C4) and their sub-criteria. The study found that the main criteria were relatively close to each other in importance based on the subjective input of the experts with the technical and safety/environment criteria tying equally with 27% followed by the managerial with 24% and trailed by the financial with 22%.

Research limitations/implications
The study and surveys were conducted for the Saudi market and the experts were within the country.

Originality/value
The study contributes to the Saudi housing initiative which is a part of the 2030 Vision and provides insight to international investors who would be willing to invest in the Saudi market; and to the literature as there is a notable lack of study on public-private partnership in housing in Saudi Arabia.
Formalism in online education
Authors: Serdyukov Peter 
Published: April 2021

PurposeWith the rapid transition of education from the traditional, classroom- or campus-based to the online format, there grows a need for not only taking advantage of online technology but also assessing actual and potential effects it can make on the learners, learning, education, and society. One of the risks inherent in online learning is its growing formalization both in the organization of the learning and in its process, which may gravely affect students’ learning, health, cognition, behavior and quality of the learning outcomes. It can also produce serious implications for the society. This article investigates the origins of formalization, its forms and stages, and discusses asynchronous, precision, and automated learning formats from this perspective. Among many issues, the impact of formalization on the learner's development and socialization is considered. The author offers a pragmatic solution for deformalization of online learning.Design/methodology/approachQualitative analysis of contemporary research literature, educational trends and practices.FindingsIt was found that formalism permeates online education in many ways. It is present in asynchronous, precise and automated learning and may produce significant impact on students, their learning, and society.Research limitations/implicationsThis is a qualitative research based on the analysis of current research literature and teaching practices.Practical implicationsWhile formalism in education is an unavoidable evil, its impact must be diminished. Critical analysis and practical recommendations offered may help improve online teaching and learning.Social implicationsFormalism affects both students' socialization in the online learning environment, and patterns of socialization in the society. It also impacts students’ cognition and behaviors. So, counteracting formalism may benefit the society's well-being.Originality/valueThe authors could not find any publications on this topic. So this is an original material which may contribute to improving online teaching and learning.
Fair trade coffee and inclusive globalization: a metamorphosis of institutional entrepreneurship
Authors: Zhu Rong , Sun Sunny Li , Huang Ying 
Published: April 2021

PurposeInitiated by non-governmental organizations (NGOs) over half a century ago, fair trade has successfully evolved from a regional business discourse to a global social movement within international trade. In the matter of fair trade coffee, this global social movement has transformed the traditional coffee trade structure of inequality and unfairness into a conglomerate of international institutions that embrace equity and inclusivity – a metamorphosis that can be attributed to NGOs’ institutional entrepreneurship.Design/methodology/approachIn this exploratory study, the authors examine the fair trade coffee industry and trace the actions of NGOs along with other stakeholders at the organizational field level, in moving toward an inclusive model of globalization.FindingsDeparting from exploitative globalization, fair trade practices advocate inclusive growth through the promotion and establishment of greater equity for all as well as higher environmental standards in global value chains.Research limitations/implicationsThis study contributes to nascent research on inclusive growth by analyzing how fair trade promotes inclusive growth and trade in GVCs. This study also contributes to research on institutional entrepreneurship by examining two enabling conditions – the shift in institutional logics and the peripheral social position of NGOs – that enabled NGOs to serve as institutional entrepreneurs in the initiation phase of institutional entrepreneurship.Practical implicationsPolicymakers may encourage collaboration between profit organizations and nonprofit organizations to provide entrepreneurial opportunities for trials, errors, and revisions. The evolution of fair trade coffee provides such an example.Social implicationsThe coevolution of NGOs and MNEs has made the globalization of fair trade practices possible. The collaboration between NGOs as institutional entrepreneurs (operating on the community logic) and MNEs as institutional followers (operating on the financial logic) support inclusive globalization and sustain fair trade practices.Originality/valueDrawing on the process model of institutional entrepreneurship, the authors seek to understand the role of NGOs as institutional entrepreneurs in the dynamics of initiating, diffusing and sustaining fair trade coffee practices.
Leaning online education during COVID-19 pandemic – attitudes and perceptions of non-traditional adult learners
Authors: Singh Jitendra , Matthees Barbara , Odetunde AnaLisa 
Published: April 2021

Purpose
The purpose of this paper is two-fold: to describe how Lean methodology can be used, during the COVID-19 pandemic, to enhance the learning experience for non-traditional adult learners (NALs) and to explore attitudes and perceptions of students toward the integration of Lean methodology in online classes.

Design/methodology/approach
Qualitative semi-structured interviews were used to collect data for the study. NALs were invited to participate in 60–75 min semi-structured interviews. These interviews allowed researchers to gain an in-depth understanding of a participant’s experience. A six-step thematic analysis framework was used to conduct the data analysis.

Findings
This paper presents a Lean model that can be implemented in an online medium of instruction. The core concepts of Lean methodology: jidoka, just-in-time, customer-centered approach, team involvement and standardization and how these can be used in online learning have been described in-depth. In total, 40 students participated in the semi-structured interviews. Four themes emerged from the data analysis: work-life balance; lack of standardization; learning online classes and connection to the workplace.

Practical implications
These findings could help academic institutions, instructors and course designers as they work on implementing new teaching and learning strategies for NALs.

Originality/value
There is extremely limited evidence on the usage of Lean methods for NALs in a public health crisis. As academic institutions move to the online medium of instruction to contain public health problems, this project can provide important practical tips to instructors.
Study on efficacy of moringa stenopetala seed oil extract for antimicrobial activities on textile materials
Authors: Gebino Gemeda , Ketema Gezu , Fenta Adina , Rotich Gideon Kipchirchir , Debebe Ayalew 
Published: April 2021

Purpose
The purpose of this study was to evaluate the extract of Moringa stenopetala seed oil, by organic solvents (methanol and hexane), for its efficacy against microbial activity on cotton fabrics. The selected microbes for the study were two types of bacteria which are Gram-positive (S. aureus) and Gram-negative (E. coli).

Design/methodology/approach
Two types of bacteria, Gram-positive (S. aureus) and Gram-negative (E. coli) were used. The extract was applied on fabrics at a concentration of 5, 10 and 15 g/L using the pad-dry-cure method and antibacterial activities verified by the bacterial-growth reduction method. The treated fabrics were evaluated for antimicrobial activity against the bacteria before and after 15 washing cycles. The extract was examined for molecular structural change using fourier transform infrared spectroscopy (FTIR) and physical properties of the fabric; tensile strength, elongation, air permeability, stiffness and wettability were evaluated.

Findings
Results showed treated fabrics reduces the growth of Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria from 77.6%–100% before wash and 45.8%–85.2% after wash for both extract concentrations. Comparing extracts, hexane extract reduces all bacteria growth than methanol extract for both extract concentrations while S. aureus was more susceptible to antimicrobial agents than E. coli at a lower concentration. As result, the tensile strength and air permeability were relatively lower than untreated ones without affecting the comfort properties of the fabric.

Originality/value
This study indicates that the Moringa stenopetala seed oil extract has a strong antimicrobial activity.
Can overtourism be managed? Destination management factors affecting residents’ irritation and quality of life
Authors: Mihalic Tanja , Kuščer Kir 
Published: April 2021

Purpose
This paper aims to present a model to survey if effective destination management can manage (unsustainable) overtourism from the perspective of residents’ quality of life (QOL).

Design/methodology/approach
A constructivist approach, based on factors taken from conceptual overtourism model (Mihalic, 2020), was used to propose an overtourism QOL management model. Relationships among the factors were analysed with a path analyses model with two second-order latent factors. The model was tested in a real setting, the city of Ljubljana.

Findings
The proposed theoretical model is comprised of five factors: positive tourism impacts, negative tourism impacts, irritation with overtourism, residents’ QOL and destination management. Empirical tests confirmed the model. Positive tourism impacts positively affected residents’ QOL via destination management. Negative tourism impacts created overtourism-based resident irritation and negatively impacted their QOL.

Research limitations/implications
The model was limited to one group of sustainable tourism stakeholders: residents of a destination. The sustainability performance of tourism was only assessed based on residents’ QOL.

Practical implications
The proposed model adds to the conceptual knowledge of tourism and may be useful for (sustainable) destination managers to monitor the existence and causes of overtourism and may help to focus efforts to manage the causes of overtourism irritation and improve residents’ QOL.

Originality/value
Overtourism is a concern for residents of tourism destinations who become irritated by unsustainable tourism impacts on community resources and their QOL. The suggested model is the first to address destination management’s ability to manage unsustainable overtourism.
On recyclability of thermoplastic ABS polymer as fused filament for FDM technique of additive manufacturing
Authors: Chawla Kapil , Singh Rupinder , Singh Jaspreet 
Published: April 2021

Purpose
The thermoplastic polymers do not decompose easily due to the presence of long-chain stable polymeric structure, and thus, causes serious effects on the environment. Recycling of these polymer wastes becomes the only solution to minimize their adverse effects on the environment. The purpose of this study was to explore the feasibility of using recycled thermoplastic material as filament for fused deposition modeling technique.

Design/methodology/approach
In this study, the researchers fabricated fused filaments (in-house) for fused deposition modeling (FDM) technique of additive manufacturing from secondary recycled acrylonitrile butadiene styrene (ABS) by using a twin-screw extruder. After measuring the melt flow index of the secondary recycled ABS, the twin-screw extrusion parameters (rpm/speed of the screw, extrusion temperature and load) were varied to predict their influence on the various properties (rheological/mechanical/thermal) of the fabricated filaments. Experimental work was executed as per Taguchi’s L9 orthogonal array.

Findings
Thermal analysis performed to estimate the heat carrying capacity of recycled ABS highlighted that the heat capacity of ABS increases significantly from 0.28 J/g to 3.94 J/g during the heating cycle. The maximum value of peak strength and percentage break elongation for the fused filaments was investigated at 12.5 kg load, 2,250 C extrusion temperature and 70 rpm speed.

Originality/value
The filaments fabricated by recycling the polymeric waste has been successfully used in the FDM machine for the preparation of the three-dimensional printed tensile specimen.
Variation in seed dormancy and germination among populations of Silybum marianum (Asteraceae)

Published: April 2021

AbstractMilk thistle (Silybum marianum) is a medicinal plant; however, lack of consistency in past dormancy studies has hindered propagation of this species from seeds. We tested the germination responses of freshly harvested and after‐ripened (stored for 2 and 7 months; 25°C at 50% relative humidity) seeds from three populations (P1, P2 and P3) in Iran at varying constant or alternating temperatures, with or without GA3 and in light and continuous darkness. No germination occurred in freshly harvested seeds incubated at any condition without GA3 application, indicating that all the seeds were dormant. Seeds from P1 and P2, which developed under relatively dry, warm conditions, germinated over a wider range of temperatures after 2 months of dry storage, indicating type 6 of non‐deep physiological dormancy (PD). Seeds from P3, which developed under relatively wet, cool conditions, incubated at constant temperatures (especially on GA3), exhibited an increase in maximum temperature for germination, indicating type 1 of non‐deep PD. Light improved germination of after‐ripened seeds, and GA3 application substituted for the light requirement for germination. This is the first report that environmental conditions during seed development may be correlated with differences in the type of non‐deep PD. We conclude that milk thistle seeds are positively photoblastic and photodormant and the germination responses of after‐ripened seeds from different populations are different under darkness. Therefore, the impacts of genetic differences and maternal effects on the induction of dormancy during seed development should be considered in attempts to domesticate this medicinal plant.
A fungal sirtuin modulates development and virulence in the insect pathogen, Beauveria bassiana
Authors: Cai Qing , Tian Li , Xie Jia‐Tao , Huang Qiu‐Ying , Feng Ming‐Guang , Keyhani Nemat O. 
Published: April 2021

SummaryChromatin transitions are mediated in part by acetylation/deacetylation post‐translational modifications of histones. Histone deacetylases, e.g. sirtuins (Sir‐proteins), repress transcription via promotion of heterochromatin formation. Here, we characterize the Sir2 class III histone deacetylase (BbSir2) in the environmentally and economically important fungal insect pathogen, Beauveria bassiana. BbSir2 is shown to contribute to the deacetylation of lysine residues on H3 and H4 histones. Targeted gene knockout of BbSir2 resulted in impaired asexual development, reduced abilities to utilize various carbon/nitrogen sources, reduced tolerance to oxidative, heat, and UV stress, and attenuated virulence. ΔBbSir2 cells showed disrupted cell cycle development and abnormal hyphal septation patterns. Proteomic protein acetylation analyses of wild type and ΔBbSir2 cells revealed the differential abundance of 462 proteins and altered (hyper‐ or hypo‐) acetylation of 436 lysine residues on 350 proteins. Bioinformatic analyses revealed enrichment in pathways involved in carbon/nitrogen metabolism, cell cycle control and cell rescue, defence and mitochondrial functioning. Critical targets involved in virulence included LysM effector proteins and a benzoquinone oxidoreductase implicated in detoxification of cuticular compounds. These data indicate broad effects of BbSir2 on fungal development and stress response, with identification of discrete targets that can account for the observed (decreased) virulence phenotype.
