Understanding individuals' engagement and continuance intention of MOOCs: the effect of interactivity and the role of gender
Authors: Shao Zhen , Chen Kuanchin 
Published: December 2020

PurposeThis study aims to examine how three perceived interactivity attributes of massive open online courses (MOOCs), namely, perceived active control, perceived synchronicity and perceived two-way communication, impact individuals' engagement and continuance intention of MOOCs through the stimulus-organism-response (S-O-R) lens and how that effect differs between male and female users.Design/methodology/approachDrawing upon S-O-R as an overarching theoretical framework, this study conducted an empirical study in China and collected 294 valid questionnaires from online learners. Structural equation modeling approach was used to examine the proposed research model.FindingsEmpirical results suggest that perceived active control, perceived synchronicity and perceived two-way communication are significant stimuli of individuals' continuance intention of MOOCs, and the influences of perceived active control and perceived synchronicity are partially or fully mediated by engagement on the platform. Multi-group analysis results further indicate that perceived synchronicity has a stronger influence on engagement on the platform for males, while perceived active control and perceived two-way communication are more salient in stimulating engagement on the platform for females.Practical implicationsResearch findings from the present study can serve as the foundation to guide MOOCs’ administrators to respond to the needs of participants through interactivity designed into the platform and shed light on possible key solutions of high dropout rates in MOOCs.Originality/valueThis study uncovers the mediating mechanism of affective engagement between interactivity and continuance intention in the emerging context of the latest online learning platform MOOCs and reveals the behavioral differences between females and males regarding their affective reactions to the three interactivity attributes.
Linking supplier selection and management strategies with mass customization capability
Authors: Ullah Inayat , Narain Rakesh 
Published: December 2020

Purpose
Owing to the paucity of literature, in the specific context of mass customization (MC), that explains what factors need to be considered while selecting suppliers and what strategies need to be implemented for effective management of suppliers, this paper aims to explore the effective supplier selection and management strategies and also investigate their impact on the development of mass customization capability (MCC).

Design/methodology/approach
Through an extensive review of literature, a total of 18 factors for supplier selection and management have been identified. Further, using multiple regression analysis, the linkages between these factors and MCCs have been examined based on the data set from the survey of Indian manufacturing organizations.

Findings
The results indicate that while concentrating on the responsive and reconfiguration capability, all the five measures of supplier selection and the four measures of supplier management have shown a significant influence. However, in the case of relational capability, only two of the supplier selection strategies and three of the supplier management strategies have shown a notable impact.

Practical implications
The study provides help to the firms in deciding whom to select and how to manage the suppliers in the course of improving their MCCs. The study has shown the possibility that different types of MCCs might require different approaches to both the supplier selection and management.

Originality/value
To the best of the authors’ knowledge, this study happens to be the first of its kind that investigates the interconnectedness among the supplier selection and management strategies and MCCs.

Authors: Basilio Marcio Pereira , Pereira Valdecy , Oliveira Max William Coelho de , Costa Neto Antonio Fernandes da 
Published: December 2020

Purpose
The purpose of this study is modelling of a problem of policing strategy order using a multicriteria method.

Design/methodology/approach
For the construction of the impact matrix strategies under the reduction of crime rates, considering a portfolio of crimes, a questionnaire applied to specialists was used. In a second moment, defined the criteria and strategies to be ordered, the multicriteria PROMETHEE II method was used, which with the help of the Visual PROMETHEE software, emulated the systematised data in the impact matrix and produced the final ordering of the most efficient strategies, in the fight against crime, in the perception of decision makers.

Findings
As a result, this research revealed that radio patrol, when used in a non-randomised manner, is the most effective policing strategy in reducing the 18 criminal demands studied in the perception of decision makers after data emulation with the PROMETHEE II method.

Research limitations/implications
As research implications, it can be inferred that the use of multicriteria methods in the modelling of problems in public security area can contribute to the rationalisation of use of the available means in the fight against crime in large cities. This research showed that it is possible to use customised policing strategies to absolute reality.

Practical implications
The practical impact of this research lies in optimising the resources available to law enforcement agencies in the fight against crime in general.

Social implications
It can be inferred that by choosing appropriate strategies to combat local crime, there is a direct implication in optimising the resources that the government makes available to police agencies. This optimisation allows pressure reduction under the public budget for more features. The model for choosing more effective strategies contributes to local crimes decrease, increasing the sense of the population security.

Originality/value
The originality lies in filling a gap in the literature with the elaboration of the impact matrix of policing strategies in reducing criminal indices and in their associated use in ordering strategies through a multicriteria method. This study contributed to applied police intelligence.
Assessment of employees’ attitudes toward ongoing organizational transformations
Authors: Heim Irina , Sardar-Drenda Nibedita 
Published: December 2020

PurposeGlobal companies in the digital service industry are experiencing a pressing urgency for ongoing transformations caused by external factors driven by the need to change business models. This study aims to evaluate the willingness and ability to change as constructs of employee attitude toward change, assess their predictors and develop an approach to analyzing willingness and ability to change.Design/methodology/approachThis study uses an abductive approach, building on the refinement of existing theories. The authors conducted 306 employees' surveys and nine interviews to collect primary data.FindingsThe result of this study suggests that the employees are willing to change when they have a sense of perceived control based on collaboration with management. Factors that have an impact on the willingness and ability to change include job function, age, years of job experience, knowledge of values, company background, understanding the current challenges, understating the urgency for change, positive attitude toward past changes and trust in leadership.Research limitations/implicationsThis is research is focused on one organization, and research in other industries or firms in the digital service industry would be beneficial.Practical implicationsThis research contributes to the practice on the conduct of diagnostic investigation in an organization's readiness and risk for a planned change. The authors add to the existing literature the new dimensions related to the prior experience with change and understanding the need and urgency for change -specific factors that are relevant to individual ability to change. Managers can use findings in this study to learn how to plan and manage organizational change in the fast-paced business environment of digital service industries.Social implicationsThis research will help to understand work attitudes, emotions and behaviors and therefore will improve the well-being in the organizations experiencing transformation.Originality/valueIndividual readiness as a stand-alone concept was not enough explored in the literature, thus creating an opportunity for this study to fill the research gap. The lessons learned from this study are the following: ongoing change initiatives require longer time with a need to extend the organizational restructuring to behavioral and mindset change. This research suggests a practical approach to the assessment of change readiness in organizations. A simple model explaining factors affecting employees' willingness and ability to change has been suggested.
Transforming the role of frontline service employees for cross-selling
Authors: Yen HsiuJu Rebecca , Hu Paul Jen-Hwa , Liao Yi-Chun 
Published: December 2020

PurposeThis study aims to examine how a manager’s learning goal orientation (LGO) influences frontline service employees’ (FSEs’) engagement in cross-selling activities. Such engagements must exist before they can achieve service–sales ambidexterity. Drawing on achievement goal theory and the meaning-making perspective, this study predicts that learning-oriented managers encourage and foster FSEs’ cross-selling behaviors by facilitating their ability to derive positive meaning from the cross-selling initiative. They do so by conveying high-quality information about the initiative and related changes to individual employees, as well as by encouraging the formation of a collective perception of open communications within the work unit.Design/methodology/approachHierarchical (nested) data from 39 managers and 357 FSEs of a major logistic service company are used to test the hypotheses.FindingsAs predicted, a manager’s LGO relates positively to FSEs’ cross-selling activities, through sequential mediations of the hypothesized communication mechanisms and employees’ benefits-finding.Originality/valueA manager’s LGO is an important antecedent of FSEs’ cross-selling behaviors. This study establishes this influence and clarifies the processes by which it occurs. This study also extends previous research by specifying the important role of employees’ meaning-making, which prompts them to adopt cross-selling, as a mediator of the multilevel communication influences that result from their managers’ LGO.

Authors: Azmi Nur Farhana , Ali Azlan Shah , Ahmad Faizah 
Published: December 2020

Purpose
Built heritage constitutes the uniqueness and identity of a place. While being overlooked in existing research, built heritage in small towns is increasingly threatened by dilapidation, exhaustion and disappearance. Therefore, this study aims to examine the challenges in protecting the unique features and identity of small towns with regard to building regulations, guidelines and policies.

Design/methodology/approach
A semi-structured interview was conducted amongst a purposive sample of nine stakeholders from different organizations involved in heritage matters in Malaysia to investigate the issues and challenges facing the protection of small towns’ identity with regard to existing protection mechanisms impacting development of the towns. The data were then analyzed using the qualitative software package NVivo 8.0. The summary models imported from NVivo were created to visualize the connections between various dimensions of constructs, concepts and categories identified in the interviews.

Findings
The study found that the current issues of built heritage protection at the local level can be classified into five emergent themes: legislative, institutional, economic, social and technical issues. While absence of specific guideline for identifying local cultural places has been identified as the most fundamental issues facing the protection of unique and distinct resources in small Malaysia towns, the paper concludes with a framework of measures that can then be used for identification and protection of small town identity.

Originality/value
This study is the first of many fruitful contributions that examine heritage identification and protection mechanisms at the local level.

Authors: Joglekar-Athavale Amruta , Shankarling Ganapati , Dubey Satishchandra , Deshpande Vinita , Jaiswal Bikashkumar , Nayak Arun 
Published: December 2020

Purpose
The spectrally selective solar absorption paint is prepared from spinel-based mixed metal oxides with inorganic binder as a key component. Inorganic binder (furnace cement) is blended with mixed metal oxide pigment during synthesis. High temperature stability upto 1,100ºC is achieved by the use of this modified coating system. The purpose of this paper is to work on solar selective coating synthesis, and application of a coating as a water-borne paint is the additive key feature that helps in reduction of solvent use.

Design/methodology/approach
The paint was formulated using water-based system, and the main component of colorant was made by mixed metal oxide–based spinel pigment and highly temperature stable inorganic binder.

Findings
The paint formed shows excellent absorptive power with low emittance even at high temperature. Optical and thermal properties were determined along with adhesion, abrasion and other properties. The solar absorptance for these samples were as = 0.93–0.95 with corresponding thermal emittance of eT = 0.096 (at room temperature) and 0.2–0.22 (at elevated temperature 100°C).

Originality/value
The paint formed shows excellent absorptive power with low emittance even at high temperature. The paint can be applied in solar absorptive tower system. The obtained results indicated excellent thermal stability of prepared paint coatings. As inorganic binder was used, the paint has reduction in solvent use, and being water as a base, it is environment friendly, easy to apply and durable at high temperatures, as the binder itself is stable up to 1,500ºC.

Published: December 2020

PurposeThis study aims to evaluate and compare the macroscopic properties of commercial acrylonitrile-butadiene-styrene (ABS) processed by two different types of additive manufacturing (AM) machines. The focus is also on the effect of multiple closed-loop recycling of ABS.Design/methodology/approachA conventional direct-drive, Cartesian-type machine and a Bowden, Delta-type machine with an infrared radiant heating system are used to manufacture test specimens molded in ABS. Afterward, multiple closed-loop recycling cycles are conducted, involving consecutive AM (four times) and recycling (three times). The rheological, mechanical, morphological and physicochemical properties are investigated.FindingsThe type of machine affects the quality of the produced parts. The machine containing an infrared radiant system in a temperature-controlled chamber produces parts showing higher mechanical properties and filling fraction, although it increases the yellowing. Closed-loop recycling of ABS for AM is applicable for at least two cycles, inducing a slight increase in tensile modulus (ca. 5%) and in tensile strength (ca. 13%) and a decrease in the impact strength (ca. 14%) and melt viscosity. An increase in the filling fraction of the AM parts promotes an increase in tensile strength and tensile modulus, although it does not influence the impact strength. Furthermore, multiple closed-loop recycling does not affect the overall chemical structure of ABS.Practical implicationsControlling the environmental temperature and using infrared radiant heating during AM of ABS improves the quality of the produced parts. Closed-loop recycling of ABS used in AM is feasible up to at least two recycling steps, supporting the implementation of a circular economy for polymer-based AM.Originality/valueThis study shows original results regarding the assessment of the effect of different types of AM machines on the main end-use properties of ABS parts and the influence of multiple closed-loop recycling on the characteristics of ABS fabricated by the most suited AM machine with an infrared radiant heating system and a temperature-controlled environment.

Authors: Kong Fanlei , Wang Chengen , Li Yunfang , Li Xiaoguang 
Published: December 2020

AbstractPercutaneous thermal ablation is an important treatment for lung cancer and is widely used in hospitals. Puncture biopsy is generally required for pathological diagnosis before or after thermal ablation. Pathological diagnosis provides both evidence of benign and malignant lesions for ablation therapy and is of important significance for the next step in disease management. Furthermore, the sequence of ablation and biopsy affects the accuracy of pathological diagnosis, the complete ablation rate of thermal ablation, and incidence of surgery‐related complications. Ultimately, it may affect the patient's benefit from local treatment. This article reviews the research progress of traditional asynchronous biopsy followed by ablation, the emerging methods of synchronous biopsy followed by ablation, and synchronous ablation followed by biopsy in the last decade.Key pointsThe sequence of ablation and biopsy affects the accuracy of pathological diagnosis, the complete ablation rate of thermal ablation, and the incidence of surgical‐related complications.This article reviewed the recent 10 years' literature on the surgical sequence of biopsy and ablation for lung tumors, the advantages, disadvantages and indications of different orders were analyzed.
Association of hOGG1‐Cys variants with occurrence of p53 and EGFR deletion mutations in non‐small cell lung cancer
Authors: Chen Ming‐Jenn , Shen Ching‐Ju , Wang Lee , Chen Po‐Ming , Chen Chih‐Yi , Lee Huei 
Published: December 2020

AbstractBackgroundThe human 8‐oxoguanine DNA glycosylase 1 (hOGG1) gene encodes a DNA glycosylase that removes 8‐hydroxy‐2‐deoxyguanine (8‐OH‐dG) DNA damage to protect against gene mutations. The association of hOGG1 Ser326Cys polymorphism with lung cancer risk has predicted that hOGG1‐Cys variants are less effective at removing 8‐OH‐dG damage from DNA; therefore, these variants might show an increased occurrence of tumor suppressor gene and oncogene mutations. However, no evidence has yet supported this hypothesis.MethodsDirect sequencing was performed to examine the mutations of p53 and EGFR genes in lung tumors from patients with non‐small cell lung cancer (NSCLC). Polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP) was used to examine hOGG1 Ser326Cys polymorphism in this study population.ResultsA total of 99 p53‐mutated and 99 EGFR‐mutated patients with NSCLC were selected to explore the possible associations of these mutations with hOGG1 Ser326Cys polymorphism. The p53‐mutated and EGFR‐mutated patients were divided into nondeletion and deletion subgroups. P53 deletion mutations were more commonly observed in male than in female patients (P = 0.030). However, EGFR exon 19 deletion mutations were more prevalent in female and adenocarcinoma patients than in male and squamous cell carcinoma patients (P = 0.028 for genders, P = 0.017 for tumor histology). Interestingly, p53 and EGFR exon 19 deletion mutations were more frequent in patients with hOGG1 Ser/Cys + Cys/Cys hOGG1‐Cys variants than with the hOGG1 Ser/Ser genotype (P = 0.010 for p53, P = 0.032 for EGFR).ConclusionsWe suggest that the association of hOGG1 Ser326Cys polymorphism with lung cancer risk could be partially explained by increases in p53 and EGFR deletion mutations.Key pointsSignificant findings of the study
NSCLC patients with hOGG1‐Cys variants may have a higher risk of p53 and EGFR deletion mutations than with hOGG1 Ser/Ser genotype.
What this study adds
NSCLC patients with hOGG1‐Cys variants might be helpful to predict patients having higher risk of EGFR exon 19 deletion mutations and these patients who were treated with gefitinib or erlotinib could be a higher risk to occur EGFR T790M mutation.

Published: December 2020

AbstractBackgroundAccumulating evidence shows that microRNAs are aberrantly expressed and exert essential roles in the tumorigenesis and tumor progression of non‐small cell lung cancer (NSCLC).MethodsThe plasma miRNAs from five healthy donors and four NSCLC patients were profiled by miRNA microarray. The differentially expressed miRNAs from 154 primary NSCLC patients and 146 healthy donors were subjected to RNA isolation and verified by quantitative PCR (qPCR).ResultsThe miRNA microarray analysis revealed that 40 differential miRNAs between NSCLC patients and healthy donors were selected. We found that the plasma miR‐1247‐5p, miR‐301b‐3p and miR‐105‐5p levels of patients were significantly higher than those of healthy controls. The receiver operating characteristic curve (ROC) analyses revealed higher area under the ROC curve (AUC) values and higher sensitivity/specificity of carcinoembryonic antigen (CEA) in combination with miR‐1247‐5p, miR‐301b‐3p, or miR‐105‐5p were superior to that of CEA alone.ConclusionsHigh miR‐1247‐5p, miR‐301b‐3p and miR‐105‐5p expression have been demonstrated to accelerate tumorigenesis, and these three miRNAs in plasma act as novel biomarkers for the early diagnosis of NSCLC patients.Key pointsPlasma miR‐1247‐5p, miR‐301b‐3p and miR‐105‐5p act as novel biomarkers for early NSCLC and NSCLC.
