Published: June 2021

PurposeBanking industry has no option but to remain observant and redraft the contagion playbook as per the situation evolves owing to COVID-19. Therefore, this study aims to develop a model to examine empirically how effectively complaints are handled to control customer retaliation and negative e-word of mouth (eWOM) in such a pandemic situation, where banking institutions are using social media as a key platform.Design/methodology/approachA self-administered questionnaire was distributed among 309 participants who had encountered service failure and experienced complaint handling on Facebook. This study draws upon prevailing literature to test a series of hypotheses through structural equation modeling.FindingsThe findings show that effective complaint handling has a negative influence on customer retaliation in the social media environment. As a result, customer retaliation was found to have a positive association with negative eWOM. Therefore, this study has revealed that effective complaint handling will lead to decrease in customer retaliation and negative eWOM.Practical implicationsThis study carries an understanding of effective complaint handling efforts by leading banks in the social media environment during the COVID-19 pandemic. This study recommends that customized and effective efforts by the banks can influence customer retaliation and negative e-WOM.Originality/valueThe study is conducted during COVID-19 pandemic considering the impact of COVID-19 on banking sector, which is a new phenomenon. This study has highlighted how banks have modified their working methodology during pandemic situation by using Facebook as a prominent platform to redress customers’ issues and complaints.
How to build a quality management climate in a small to medium enterprise: an action research project
Authors: Bishop Desmond , Reeves Kingsley 
Published: June 2021

PurposeThe purpose of this paper is to share the successful lean implementation experience of a small to medium enterprise (SME) and the resultant performance improvement including the development of a quality management climate.Design/methodology/approachAn action research (AR) approach was used with two successive rounds of interventions.FindingsThe results from this project show that the organization was indeed able to build a quality climate as measured by the total defect count. Results include a measurable reduction in non-conformances.Research limitations/implicationsThe study took place in a single organization and, as such, it is difficult to generalize the results of the research. However, the benefit of studying one organization is the depth at which the organization may be studied. The major takeaway is that any organization of any size or any industry can increase the quality climate of the organization by intensely focusing on a minimal number of high-impact factors.Originality/valueThe research fills a gap identified in the literature regarding the critical success factors for lean implementation in SMEs and practitioner/academic collaboration in research activities. Moreover, there are very few research studies in the lean literature that provide the practical insights that may be garnered from an AR approach. Thus, both the context and methodological approach contribute to the literature.

Authors: Konkyana Lalitha Bhavani , Alapati Sudhakar 
Published: June 2021

Purpose
This paper aims to state the configuration of the proposed antenna which is competent to many networks such as LTE and X band applications. The experimental study encountered the significance of the proposed antenna.

Design/methodology/approach
A novel compact Kuznets curve with parabola-shaped quad-band notched antenna is demonstrated in this paper. The presented prototype is ascertained on a composite material composed of woven fiberglass cloth with an epoxy resin binder. The resulting ultra-wideband antenna ranges 3.1–3.54 GHz, 5.17–5.51 GHz, 5.74–6.43 GHz and 6.79–7.60 GHz. To avoid the frequency bands which cause UWB interference,the projected antenna has been incorporated with slotted patch. The proposed antenna design is attained in four steps. The simple circular patch antenna model with defected ground plane is subjected to stepwise progression by including parabola-shaped slot and U shaped slot on the patch to attain four notched bands.

Findings
This projected antenna possesses an optimal bond among simulated and measured outcomes,which is more suitable for the quad notched band applications. Substrate analysis is done by varying substrate material, and notch behavior is presented. The proposed method’s optimum performance in metrics such as return loss, voltage standing wave ratio and radiation pattern varies its frequency range from 2.56 to 7.6 GHz.

Originality/value
The antenna adaptation of the defected ground plane has achieved through the quad notched band with operating frequency ranges 2.56 to 7.6 GHz and with eliminated frequency ranges 3.55–5.16 GHz, 5.52–5.73 GHz, 6.44–6.78 GHz and 7.66–10.6 GHz.

Authors: Chapala Venkatesh , Bojja Polaiah 
Published: June 2021

Purpose
Detecting cancer from the computed tomography (CT)images of lung nodules is very challenging for radiologists. Early detection of cancer helps to provide better treatment in advance and to enhance the recovery rate. Although a lot of research is being carried out to process clinical images, it still requires improvement to attain high reliability and accuracy. The main purpose of this paper is to achieve high accuracy in detecting and classifying the lung cancer and assisting the radiologists to detect cancer by using CT images. The CT images are collected from health-care centres and remote places through Internet of Things (IoT)-enabled platform and the image processing is carried out in the cloud servers.

Design/methodology/approach
IoT-based lung cancer detection is proposed to access the lung CT images from any remote place and to provide high accuracy in image processing. Here, the exact separation of lung nodule is performed by Otsu thresholding segmentation with the help of optimal characteristics and cuckoo search algorithm. The important features of the lung nodules are extracted by local binary pattern. From the extracted features, support vector machine (SVM) classifier is trained to recognize whether the lung nodule is malicious or non-malicious.

Findings
The proposed framework achieves 99.59% in accuracy, 99.31% in sensitivity and 71% in peak signal to noise ratio. The outcomes show that the proposed method has achieved high accuracy than other conventional methods in early detection of lung cancer.

Practical implications
The proposed algorithm is implemented and tested by using more than 500 images which are collected from public and private databases. The proposed research framework can be used to implement contextual diagnostic analysis.

Originality/value
The cancer nodules in CT images are precisely segmented by integrating the algorithms of cuckoo search and Otsu thresholding in order to classify malicious and non-malicious nodules.

Published: June 2021

Purpose
Cloud computing plays a significant role in the initialization of secure communication between users. The advanced technology directs to offer several services, such as platform, resources, and accessing the network. Furthermore, cloud computing is a broader technology of communication convergence. In cloud computing architecture, data security and authentication are the main significant concerns.

Design/methodology/approach
The purpose of this study is to design and develop authentication and data security model in cloud computing. This method includes six various units, such as cloud server, data owner, cloud user, inspection authority, attribute authority, and central certified authority. The developed privacy preservation method includes several stages, namely setup phase, key generation phase, authentication phase and data sharing phase. Initially, the setup phase is performed through the owner, where the input is security attributes, whereas the system master key and the public parameter are produced in the key generation stage. After that, the authentication process is performed to identify the security controls of the information system. Finally, the data is decrypted in the data sharing phase for sharing data and for achieving data privacy for confidential data. Additionally, dynamic splicing is utilized, and the security functions, such as hashing, Elliptic Curve Cryptography (ECC), Data Encryption Standard-3 (3DES), interpolation, polynomial kernel, and XOR are employed for providing security to sensitive data.

Findings
The effectiveness of the developed privacy preservation method is estimated based on other approaches and displayed efficient outcomes with better privacy factor and detection rate of 0.83 and 0.65, and time is highly reduced by 2815ms using the Cleveland dataset.

Originality/value
This paper presents the privacy preservation technique for initiating authenticated encrypted access in clouds, which is designed for mutual authentication of requester and data owner in the system.
4W of user-generated content: why who we are and where we post influence what we post
Authors: Soylemez Kemal Cem 
Published: June 2021

PurposeIn continuation of Soylemez (2021), this study utilized equity theory and investigated how personal factors (personality traits) and community factors (ownership) influence relative generation of brand-oriented and community-oriented content.Design/methodology/approachA study of A/B testing was conducted with 104 online brand community (OBC) participants who had been active in an OBC in the last 30 days.FindingsMembers with a high level of conscientiousness, extroversion and neuroticism generate more brand-oriented content than community-oriented content. Openness to experience, agreeableness and community ownership have been found to have no significant effects.Practical implicationsThis research helps marketing practitioners on whether they should build their own online brand communities. The study also suggests that brands should adjust their community strategies based on the personality traits of community members and expectations from the community.Originality/valueThis is the first study that investigates how personality traits and community ownership influence the generation of different types of user-generated content (UGC).
The role of construal fit in threat appeal to persuade young drivers not to text while driving
Authors: Lim Dongjae (Jay) , Lin Jhih-Syuan , Chung Un Chae , Ko Youngjee 
Published: June 2021

Purpose
This paper aims to investigate the effect of matching social distance and the concrete/abstract visual presentation of the threats of distracted driving in campaign design.

Design/methodology/approach
This study conducts a series of 2 (social distance frame: close vs distant) × 2 (visual rhetoric style: literal vs metaphorical) online experiments on the perspective of the construal level theory.

Findings
This study identified that a fit between social distance and visual rhetoric style of the threat enhances the effect of a social marketing campaign targeting young adults. A message framed in terms of socially proximal entities shows a favorable impact on young drivers’ threat perception and behavioral intention when the visual rhetoric depicts the threats of texting while driving more concrete. On the other hand, more distant social entities in the message show a better impact when the threats are visualized in metaphor.

Originality/value
This paper enhances the understanding of a threat appeal message design by adding empirical evidence of matching visual rhetoric style and social distance. The findings provide theoretical and practical implications for social marketing campaigns, regarding the strategic tailoring of messages, particularly in public service announcements that discourage texting while driving on young adults.
Demoralizing: integrating J.D. Peters’ communication “chasm” with Niklas Luhmann’s (1989) ecological communication to analyze climate change mitigation inaction
Authors: Miller Jacob A. 
Published: June 2021

PurposeThe purpose of this paper is to explain the US society’s insignificant mitigation of climate change using Niklas Luhmann’s (1989) autopoietic social systems theory in ecological communication. Specifically, the author’s analysis falls within the context of Luhmann re-moralized while focusing on particular function systems’ binary codes and their repellence of substantive US climate change mitigation policy across systems.Design/methodology/approachThe author achieves this purpose by resituating Luhmann’s conception of evolution to forgo systems teleology and better contextualize the spatial-temporal scale of climate change; reinforcing complexity reduction and differentiation by integrating communication and media scholar John D. Peters’s (1999) “communication chasm” concept as one mechanism through which codes sustain over time; and applying these integrated concepts to prominent the US climate change mitigation attempts.FindingsThe author concludes that climate change mitigation efforts are the amalgamation of the systems’ moral communications. Mitigation efforts have relegated themselves to subsystems of the ten major systems given the polarizing nature of their predominant care/harm moral binary. Communication chasms persist because these moral communications cannot both adhere to the systems’ binary codes and communicate the climate crisis’s urgency. The more time that passes, the more codes force mitigation organizations, activist efforts and their moral communications to adapt and sacrifice their actions to align with the encircling systems’ code.Social implicationsIn addition to the conceptual contribution, the social implication is that by identifying how and why climate change mitigation efforts are subsumed by the larger systems and their codes, climate change activists and practitioners can better tool their tactics to change the codes at the heart of the systems if serious and substantive climate change mitigation is to prevail.Originality/valueTo the author’s knowledge, there has not been an integration of a historical communication concept into, and sociological application of, ecological communication in the context of climate change mitigation.
Fighting the virus, “hunting the witches” – moralizing in public discourses during the coronavirus pandemic in Croatia
Authors: Žažar Krešimir 
Published: June 2021

PurposeThe purpose of the paper is to discuss particular features of the public debate around the COVID-19 pandemic and its mitigation strategies in Croatian media from the beginning of 2020 to mid-September of the same year.Design/methodology/approachThe discussion is theoretically grounded on Luhmann’s concept of moral communication combined with the key assumption of critical discourse analysis that language reflects a position of power of social actors. Based on these premises, the analysis of a sample of articles in a chosen online media was conducted to uncover the moral codes in the public debate concerning the corona outbreak and connect them with specific moral discourses of particular social actors.FindingsThe findings clearly indicate that the communication about the pandemic is considerably imbued with moralization and that moral coding is profoundly used to generate preferred types of behaviour of citizens and their compliance with the imposed epidemiologic measures. In conclusion, Luhmann’s claim of moralization as a contentious form of communication is confirmed as the examined public discussion fosters confrontations and generates disruptions rather than contributing to a productive dialogue among diverse social actors.Originality/valueThe novelty of the approach lies in the combination of Luhman’s conceiving of moral communication with critical discourse analysis that, taken together, entails a pertinent research tool for analysing relevant attributes of the ongoing vibrant debate on the coronavirus outbreak.
The future of work: how HR drives digital transformation in the new normal
Authors: Chandrasekaran Ramkumar 
Published: June 2021

Purpose
The purpose of this paper is to shed light on how organisations can leverage digital transformation by discussing the importance of having a zero-trust approach when it comes to security. This is something that is imperative, and so this paper aims to provide advice on how organisations can keep their networks and systems safe from cyberattacks and opportunistic cybercriminals.

Design/methodology/approach
This paper is a thought leadership piece and draws on Tata Consultancy Services (TCS’) COVID-19 Business Impact Survey, which surveys nearly 300 executives on how they are planning and managing the near and long-term impacts of the coronavirus pandemic. Those surveyed represented mostly large companies across 11 countries in North America, Europe and Asia-Pacific. Moreover, 63% of these companies had an annual revenue of over $5bn.

Findings
The findings from the survey revealed that most organisations lack digital capabilities, and the coronavirus pandemic is exposing these weaknesses. It found that companies with essential digital capabilities (“leaders”) have held up better during the pandemic than those without (“followers). Moreover, the survey demonstrated that there is a significant lack of clarity on how to strategically move on multiple digital fronts cost-effectively.

Originality/value
As TCS is a global leader in information technology services, consulting and business solutions, this paper provides value to senior business and technology leaders in organisations that hold influence over the company’s security strategies. By focussing on zero trust, this paper recommends how such leaders can rethink and reassess their business strategy to thrive in a post-pandemic world.

Published: June 2021

AbstractThe endoplasmic reticulum (ER) is responsible for protein synthesis and calcium storage. ER stress, reflected by protein unfolding and calcium handling abnormalities, has been studied as a pathogenic factor in cardiovascular diseases. The aim of this study is to examine the effects of ER stress on mechanical and electrophysiological functions in the heart and explore the underlying molecular mechanisms. A total of 30 rats were randomly divided into control, ER stress inducer (tunicamycin[TN]) and ER stress inhibitor (tunicamycin+4‐phenylbutyric acid [4‐PBA]) groups. ER stress induction led to significantly systolic and diastolic dysfunction as reflected by maximal increasing/decreasing rate of left intraventricular pressure (±dp/dt), left ventricular peaksystolic pressure(LVSP) and LV end‐diastolic pressure(LVEDP). Epicardial mapping performed in vivo revealed reduced conduction velocity and increased conduction heterogeneity associated with the development of spontaneous ventricular tachycardia. Masson’s trichrome staining revealed marked fibrosis in the myocardial interstitial and sub‐pericardial regions, and thickened epicardium. Western blot analysis revealed increased pro‐fibrotic factor transforming growth factor‐β1 (TGF‐β1), decreased mitochondrial biogenesis protein peroxlsome proliferator‐activated receptor‐γ coactlvator‐1α （PGC‐1a）, and decreased mitochondrial fusion protein mitofusin‐2 (MFN2). These changes were associated with mitochondria dysfunction and connexin 43(CX43)translocation to mitochondria. These abnormalities can be partially prevented by the ER stress inhibitor 4‐PBA. Our study shows that ER stress induction can produce cardiac electrical and mechanism dysfunction as well as structural remodelling. Mitochondrial function alterations are contributed by CX43 transposition to mitochondria. These abnormalities can be partially prevented by the ER stress inhibitor 4‐PBA.
