Published: September 2021

We report the effect of controlled particle size (obtained by using 80, 100, 120, 140 and 200 mesh) of the source materials on the synthesis of a well-known biomaterial, hydroxyapatite (Hap). In addition to this, we have also mapped the consequence of applied temperature (700°C, 800°C and 900°C) on the crystallographic properties and phase composition of the obtained Hap. Nevertheless, although with Hap, in each case, β-tricalcium phosphate (β-TCP) was registered as the secondary phase the ANOVA test revealed that the results of the crystallographic parameters are significantly different for the applied sintering temperature 700°C and 800°C (
p
< 0.05), while the data obtained for calcination temperature 800°C are not significantly different from that acquired at 900°C (
p
> 0.05). Fourier transform infrared spectrophotometer data ensured that, irrespective of mesh size and calcination temperature, the synthesized Hap samples were of carbonated apatite with B-type substitution. Interestingly, for all cases, the % of carbonate content was below the maximum limit (8%) of the

Published: September 2021

AbstractEstablishing an effective way to propagate a wide range of arbuscular mycorrhizal (AM) fungi species is desirable for mycorrhizal research and agricultural applications. Although the success of mycorrhizal formation is required for spore production of AM fungi, the critical factors for its construction in the in vitro monoxenic culture protocol remain to be identified. In this study, we evaluated the growth of hairy roots from carrot, flax, and chicory, and investigated the effects of the phosphorus (P) concentration in the mother plate, as well as the levels of P, sucrose, and macronutrients in a cocultivation plate with a hairy root, amount of medium of the cocultivation plate, and location of spore inoculation, by utilizing the Bayesian information criterion model selection with greater than 800 units of data. We found that the flax hairy root was suitable for in vitro monoxenic culture, and that the concentration of P in the cocultivation plate was a critical factor for mycorrhizal formation. We showed that an extremely low concentration of P (3 μM) significantly improved mycorrhizal formation for AM fungi belonging to the Glomerales order, while a high concentration of P (30 μM) was suitable for Diversisporales fungi. Therefore, we anticipate that the refining the P concentration will contribute to future culture collections of a wide range of AM fungi.

Published: September 2021

Purpose
This paper aims to present an investigation on flight quality analysis and design of tilt-rotor aircraft combined with corresponding flight quality specifications.

Design/methodology/approach
From the perspective of modal characteristics of tilt-rotor aircraft, it focuses on the analysis of the change rules of the longitudinal short-term motion mode, lateral roll convergence mode, spiral mode and Dutch roll mode. Then, the flight quality design research is carried out using the explicit model tracking control method. The quantitative relationship between flight quality requirements and explicit model is established. Accordingly, the closed-loop flight quality of XV-15 tilt-rotor aircraft is evaluated.

Findings
The stability of spiral mode is the result of the interaction of various aerodynamic derivatives and spiral instability occurs in helicopter mode. The other motion modes are stable in full flight mode and meet the requirements of level 1 specified in ADS-33E-PRF and MIL-F-8785C flight quality specifications. There is a quantitative relationship between flight quality requirements and explicit model, and the flight quality of tilt-rotor aircraft is improved through the explicit model tracking control method.

Practical implications
The presented analysis results showed the influence of motion modes and flight quality and the effectiveness of explicit model tracking control method in flight quality improvement, which could be considered as new information for further flight quality design of tilt-rotor aircraft.

Originality/value
The originality of the paper lies in the proposed design and analysis method of the flight quality of tilt-rotor aircraft from the direction of the influence of its aerodynamic derivatives and motion modes.

Authors: Magnini Vincent P. , Quendler Erika , Uysal Muzaffer 
Published: September 2021

PurposeUsing the context of a farm holiday venue, the purpose of this study is to empirically test whether textual references can have significant influences on potential consumers' affective responses and interest in advertisements.Design/methodology/approachIn a between-subjects experiment, a reference to sunshine (the underlined phrase in the following narrative) was inserted into a Facebook advertisement for a farm holiday venue: “Relax and Rejuvenate for a couple of days on our farm. Great food, fun, and sunshine … See More”.FindingsResults indicate that a reference to sunshine significantly improves consumers' affective responses to the advertisement and significantly increases their interest (propensity to click “see more”). This study also examines the potential influence of a textual reference to fresh air as well as fresh air in combination with sunshine. No statistically significant results are found with the fresh air reference.Originality/valueWhile a number of studies have examined text-based sensory details in marketing stimuli (Magnini and Gaskins, 2010; Torto, 2016), the notion of inserting textual references to fresh air and/or sunshine in advertising has not been empirically examined in the body of the existing literature.

Published: September 2021

PurposeThis study investigates the impact of agri-food supply chains (AFSCs) characteristics on the antecedents of horizontal logistics collaboration (HLC). Specifically, the study compares the relationship between collaboration activities and outcomes for companies in and outside AFSCs.Design/methodology/approachFirst, a survey was used to collect data from different industries. Second, confirmatory factor analysis and structural equation modeling were applied to compare the measurement and structural models from different industry categories.FindingsThe results support the premise that collaboration improves trust and commitment in the relationship, which in turn enhance satisfaction. The results also show the existence of a minor influence of AFSCs characteristics on HLC antecedents, in the form of an indirect impact of dedicated investments on commitment.Practical implicationsThe factors having a significant influence on the collaboration outcomes and their respective effects are generally similar across food and nonfood supply chains, providing opportunities for interdisciplinary and collaboration experiences.Originality/valueThis research contributes to the body of knowledge on interfirm collaboration by considering the specificities of HLC. It also highlights the importance of conducting contingency research on collaborative experiences, as firms from different industry contexts operate under distinct operational conditions.

Authors: Manurung Adler Haymans , Kurniawan Randy 
Published: September 2021

PurposeThis study aims to examine the joint impact of networking capability and agile project management on organizational agility of telecommunication technology providers' in Indonesia. The study also examines the moderating role of market orientation as a predominant strategic orientation on the relationship between agile project management and organizational agility.Design/methodology/approachResearch data were collected via a questionnaire survey from the executive management of telecommunication technology providers in Indonesia to obtain 150 valid questionnaires for analysis. This study analyzed the overall model fit and causal relationship using confirmatory factor analysis and structural equation modeling.FindingsThe results indicate that networking capability positively affects organizational agility. However, agile project management's significant effect on organizational agility occurs only when the relationship is moderated by market orientation. The results of the study also demonstrate that organizational agility positively affects organizational performance.Research limitations/implicationsThis study is based on a cross-sectional nature and might fail to capture the studied variables' dynamic over an extended period.Originality/valueThe study enriches the previous literature in organizational agility by presenting the collective impact of networking capability and agile project management and the moderating role of market orientation. However, dissimilar with major prior studies, the results indicate that agile project management's direct effect on organizational agility is not significant. Agile project management needs to be moderated by market orientation to create exceptional customer values and overcome the competition for the organization to achieve organizational agility, responsiveness and adaptability to address customers' needs and requirements. Furthermore, the study's result corroborates the importance of organizational agility to achieve organizational performance in the highly dynamic telecommunication industry.

Authors: Herro Danielle , Quigley Cassie , Abimbade Oluwadara 
Published: September 2021

PurposeThe purpose of this study is to identify and assess collaborative problem solving (CPS) behaviors in elementary students in science, technology, engineering, arts/humanities and mathematics (STEAM)-related making and to garner students perspectives. We offer a valid way for researchers to understand collaborative processes and for educators to create opportunities for collaboration. Additionally, the feedback from the assessment offers students a way to reflect on their CPS skills.Design/methodology/approachThis qualitative study evaluated 52 elementary students’ CPS skills using co-measure, a validated rubric assessing students’ CPS when working in STEAM-related makerspace activities. Students worked in collaborative groups to “make” artifacts when solving a problem posed by their teacher. They were assessed using co-measure’s four dimensions: peer interactions, positive communication, inquiry rich/multiple paths and transdisciplinary approaches and scored via each dimension’s associated attributes. Student interviews provided their perspectives on CPS.FindingsA majority of students scored in the acceptable or proficient range in the social dimensions of peer interactions and positive communication. Students scored slightly lower on the cognitive dimensions of inquiry rich/multiple paths and markedly lower on transdisciplinary approaches when collaborating. Findings suggest to increase CPS skills, teachers might develop “making” activities fostering greater inquiry and model ways to strategize and verify information, approach the problem drawing on student interest and prior knowledge and collaboratively use tools, materials and methods that mimic the real world when problem-solving.Originality/valueMuch of the current research on assessing CPS during making is in the early stages of considering appropriate assessment approaches, especially in schools. To expand this literature the study includes elementary students between the ages of 6-10, the focus is on assessing their collaboration using an observational rubric. The authors use preliminary findings from young children’s perspectives on making to position the future work.

Published: September 2021

PurposeThe purpose of the research is to assess the risk of the financial market in the digital economy through the quantitative analysis model in the big data era. It is a big challenge for the government to carry out financial market risk management in the big data era.Design/methodology/approachIn this study, a generalized autoregressive conditional heteroskedasticity-vector autoregression (GARCH-VaR) model is constructed to analyze the big data financial market in the digital economy. Additionally, the correlation test and stationarity test are carried out to construct the best fit model and get the corresponding VaR value.FindingsOwing to the conditional heteroscedasticity, the index return series shows the leptokurtic and fat tail phenomenon. According to the AIC (Akaike information criterion), the fitting degree of the GARCH model is measured. The AIC value difference of the models under the three distributions is not obvious, and the differences between them can be ignored.Originality/valueUsing the GARCH-VaR model can better measure and predict the risk of the big data finance market and provide a reliable and quantitative basis for the current technology-driven regulation in the digital economy.

Authors: Vendrell-Herrero Ferran , Gomes Emanuel , Opazo-Basaez Marco , Bustinza Oscar F. 
Published: September 2021

PurposeThe purpose of this paper is to distinguish clearly between industry (ILC) and product lifecycle (PLC) models and to elucidate their different ramifications for organizational learning and knowledge.Design/methodology/approachThe authors examine existing knowledge on ILCs and PLCs to highlight the differences and similarities and develop a framework with implications for learning and innovation in digital manufacturing industries.FindingsThe authors identify and associate one dominant type of learning with each phase of the ILC: learning-by-participating in the introduction phase, learning-by-feedback in the growth phase, vicarious learning in the maturity phase and learning-by-memory in the decline phase. The study also provides insight into how different types of learning influence PLC in digital innovation. From this perspective, learning-by-feedback is crucial to co-creation, co-production and open innovation. Similarly, learning-by-doing and learning-by-memory are essential to production and usage stages, respectively.Research limitations/implicationsThe conceptual development in this paper follows a somewhat critical but ultimately elucidative analysis that highlights important research avenues in the interplay of PLC/ILC, organizational learning and digital innovation.Originality/valueThis paper clarifies a perennial theoretical problem by differentiating two concepts often conflated in the literature. More importantly, it contributes to the knowledge management literature by shedding light on the connection of ILC and PLC theories to different types of organizational learning.
Knowledge creation in patent ecosystems: insights from Singapore
Authors: Schillaci Carmela Elita , Marku Elona , Castriotta Manuel , Di Guardo Maria Chiara 
Published: September 2021

PurposeThis paper aims to better understand how codified knowledge that originates in organizations contributes to the generation of idiosyncratic knowledge embedded at a more expansive level, such as that of an ecosystem. In doing so, the authors introduce the concept of patent ecosystems – conceived as configurations of codified knowledge advancements protected via patents.Design/methodology/approachUsing a patent co-classification method and introducing a novel validated software, the authors map and visualize the patent ecosystem of Singapore and examine 173,597 patents published from 1995 to 2020.FindingsResults reveal the prominent growth of Singapore’s patenting activities, capturing a patent ecosystem shift, from a more diverse knowledge configuration to a more specialized one. The codified knowledge mainly generated deals with pharmaceuticals and high-tech knowledge domains; further, newly emerging technologies such as blockchain are also noted.Research limitations/implicationsThe research investigates Singapore’s context, a country in which research directions and focus areas are influenced by government interventions and leadership. Thus, future studies might examine other patent ecosystems to draw comparisons with more laissez-faire policies or ecosystems with more pronounced organic development.Originality/valueThe novelty of this research is the introduction of the concept of a patent ecosystem for advancing a more fine-grained understanding of the aggregated knowledge generated at the ecosystem level and its specific features, composition and development. The authors consider patents as “carriers” of different codified pieces of knowledge and patent ecosystems represent the configuration that emerges from connections of these elements. The novel approach can aid both researchers, practitioners and policymakers with future examinations in the field.
Exploring workplace dignity from managerial lens
Authors: Tiwari Anjali , Sharma Tanuja , Sharma Radha R. 
Published: September 2021

PurposeUnderstanding managers’ experiences of workplace dignity (WPD) is critical to working with others in an organization. However, there is limited research available on this subject. This study aims to expand the knowledge of WPD by exploring managers’ understanding of WPD and their experiences of both affirmation and denial of dignity at work.Design/methodology/approachCritical incident technique (CIT) has been used to explore the themes related to managers’ perceptions of WPD through their lived experiences. Affective event theory supports the use of CIT in the current study context.FindingsFindings unfolded many new aspects of WPD, which have not been explored in the past. An exploration and analysis of the three research questions related to managers’ understanding, affirmation and denial experiences of WPD have added new insights to the existing literature. These have been further segregated under the following four main factors: internal, external, process and feelings. Finally, the authors conclude that external factors that arrive during exchange relationships play an important role in managers’ understanding and experiences of WPD in India.Originality/valueTo the best of the knowledge, this is a seminal study to have explored managers’ understanding of WPD in India. It aims to add to the literature by enriching the construct of WPD. Practical implications include a deeper managerial understanding of the affirmational practices and factors which will positively impact WPD.
Orange-derived and lemon-derived adsorbents with controlled grain for an efficient elimination of some cationic and anionic dyes
Authors: Pascual Gemma , García-Raurich Josep , Canal José M. , Riba-Moliner Marta 
Published: September 2021

Purpose
This study aims to demonstrate that orange-derived and lemon-derived systems can be used in continuous processes as efficient adsorbents to the entrapment of some anionic and cationic dyes in the textile dyeing wastewater effluents.

Design/methodology/approach
Physically and chemically modified orange and lemon mesocarps are used as natural adsorbents for the cationic dyes Basic Blue 3, Basic Yellow 21, Basic Red 18 and Basic Green 4 and the anionic dyes Acid Blue 264, Acid Yellow 49 and Acid Red 337, all commonly used in the textile dyeing industry. Adsorption capacities of the orange-derived and lemon-derived adsorbents on the dyes are studied simulating a batch and continuous industrial processes.

Findings
Results demonstrate that treated orange mesocarp (orange-derived adsorbent) can adsorb up to 97% of cationic Basic Green 4 in 30 min, whereas the lemon mesocarp (lemon-derived adsorbent) can retain up to 88% within the same time. In the case of anionic, 91% Acid Blue 264 is adsorbed by the orange mesocarp in 15 min, whereas 92% is adsorbed by the lemon homologue within the same time.

Originality/value
As far as the authors know, physically and chemically modified orange and lemon mesocarps have not been used on the removal of cationic (Basic Blue 3, Basic Yellow 21, Basic Red 18 and Basic Green 4) and anioinic (Acid Blue 264, Acid Yellow 49 and Acid Red 337) dyes of textile dyeing wastewater industry. It is a costless and efficient treatment that supposes, on the one hand, an eco-friendly and feasible process for discolouration of wastewater and, on the other, a valorisation (upcycling) of orange and lemon peels, which are not currently used.

Published: September 2021

Purpose
The purpose of this paper is to examine the effect of internal pores on the tensile properties of a Co–Cr–Mo alloy fabricated by selective laser melting (SLM).

Design/methodology/approach
The size and volume fraction of pores were controlled through high temperature annealing (HTA) and hot isostatic pressing (HIP).

Findings
After HTA, the size and fraction of pores decreased compared with the as-built SLM sample, and no pores were observed after HIP. Tensile tests of the HTA and HIP samples showed nearly similar tensile deformation behavior. From the results, the authors found that the size of the internal pores formed in the SLM process had little effect on the tensile properties. The as-built SLM sample had less elongation than the HTA and HIP samples, which would not the effect of porosity, but rather the effect of the residual stress and the retained ε phase after the SLM process.

Originality/value
Although pores are a main factor that influence the mechanical properties, the effect of pores on the tensile properties of Co–Cr–Mo alloys fabricated by SLM has not been studied. Therefore, in this study, the effect of pores on the tensile properties of a Co–Cr–Mo alloy fabricated by SLM was studied.
