Abstract
Purpose
The demand for higher bandwidth has resulted in the development of mm-wave phased array systems. This paper aims to explore a technique that could be used to feed the individual antennas in a mm-wave phased array system with the appropriate phase shifted signal to achieve the required directivity. It presents differential Colpitts oscillators at 5 and 60 GHz that can provide differential output signals to the quadrature signal generators in the proposed phase shifter system.
Design/methodology/approach
The phase shifter system comprises a differential Colpitts voltage controlled oscillator (VCO) and utilizes the vector-sum technique to generate the phase shifted signal. The differential VCO is connected in the common-collector configuration for the 5-GHz VCO, and is extended using a cascode transistor for the 60-GHz VCO for better stability at mm-wave. The vector sum is achieved using a variable gain amplifier (VGA) that combines the in-phase and quadrature phase signal, generated from oscillator output using hybrid Lange couplers. The devices were fabricated using IBM 130-nm SiGe BiCMOS process, and simulations were performed with a process design kit provided by the foundry.
Findings
The measured results of the 5-GHz and 60-GHz VCOs indicate that differential Colpitts VCO could generate oscillator output with good phase noise performance. The simulation results of the phase shifter system indicate that the generation of signals with phases from 0° to 360° in steps of 22.5° was achieved using the proposed approach. A Gilbert mixer topology was used for the VGA and the linearity was improved by a pre-distortion circuit implemented using an inverse tanh cell.
Originality/value
The measurement results indicate that differential Colpitts oscillator in common-collector configuration could be used to generate differential VCO signals for the vector-sum phase shifter. The simulation results of the proposed phase shifter system at mm-wave show that the phase shift could be realised at a total power consumption of 200 mW.

Abstract
Purpose
All touristic cities have their unique attributes to showcase and differentiate themselves from others. This distinctive attribute is the unique selling product or tourism product of a particular city. It could be an art form, culture, regional climate, food and festival. Literature indicates that the identity of the entire city would be affected by such tourism products. The purpose of this study is to analyse the influence of the ‘image’ of an Art-event to city branding. The study also examines the mediating role of ‘city attachment’ in the relationship between event image and city brand equity.
Design/methodology/approach
In all, 432 samples have been collected from visitors to one of the biggest contemporary art events in India – the “Kochi-Muziris Biennale – 2018,” conducted in the city of Cochin, situated in Kerala, the southernmost state of India.
Findings
Results show that the direct relationship between event image and city brand equity is stronger than the hypothesised path through the mediating role of city attachment.
Research limitations/implications
This study provides a better understanding of the event image and its importance in creating the host city’s brand equity. It contributes to both the practitioners and tourism researchers.
Originality/value
This study looks at the event image through functional and affective aspects and its influence on city attachment and city brand equity.

Abstract
Purpose
This study aims to expand the emerging body of literature on employer branding from the current employee perspective. It proposes that effective integrated communication helps an organization fulfill its employer value proposition or employment value proposition (EVP). A firm that fulfills its brand promise in terms of EVP will derive employee-based brand equity (EBBE) benefits. Integrated communication is effective when employees experience coordination and consistency in brand communication. This influences their perception of psychological contract fulfillment (in terms of EVP attributes), which results in positive employee behavior in the form of EBBE benefits.
Design/methodology/approach
The study draws insights from the signaling theory and psychological contract literature which is based on the social exchange theory. The literature on integrated communication, employer branding and internal branding was reviewed to propose the relationships between the variables of interest. Data was collected using a questionnaire survey on 520 employees from the information technology (IT)-business process management industry in India, which is a customer-oriented industry known for its exemplary employer practices.
Findings
The findings suggest that integrated communication effectiveness impacts the perceived fulfillment of EVP attributes and EBBE. Again, the fulfillment of the relational value dimension of EVP attributes partially mediates the relationship between integrated communication effectiveness and EBBE.
Originality/value
This study is one of the first to explore employees’ perception of integrated communication effectiveness and fulfillment in terms of EVP attributes as antecedents to EBBE.

Abstract
Purpose: Industry 5.0 is a revolution building on the fourth industrial revolution, adopting human-centred production. It aims for a future that enables people to live with high welfare power by combining the power of the technologies it supports and uses with human creativity and skill. The study explores how Industry 5.0 differs from the industrial revolutions that preceded it, highlighting the challenges, benefits, and possible future trends of Industry 5.0 systems.
Need for the study: Industry 5.0 differs from Industry 4.0 – it represents a human-centred and sustainable approach along with the innovations it brings. Examination of the still emerging concept of Industry 5.0 and to investigate the driving forces behind the emergence is needed.
Methodology: The characteristics that distinguish the Industry 5.0 system from the fourth industrial revolution are explored in detail. The areas in which the technologies used in Industry 5.0 provide benefits and the challenges in implementing the system are analysed. The measures to be taken to overcome these difficulties and the deficiencies were investigated.
Findings: The most important principle of Industry 5.0 is human-centred production and technology. In addition, sustainability, personalised production, new business opportunities, more environmentally friendly and renewable energy use, and bioeconomy are shown as innovations brought by Industry 5.0.
Practical implications: The adoption of Industry 5.0 appears to be a mandatory change. In addition, the study emphasises the measures that businesses should take in terms of sustainability, sustainable economy, the importance of the use of renewable energy sources, and much more environmentally friendly and waste-free production.

Abstract
Purpose
In the recent years, the industries show interest in natural and synthetic fibre-reinforced hybrid composites due to weight reduction and environmental reasons. The purpose of this experimental study is to investigate the properties of the hybrid composites fabricated by using carbon, untreated and alkaline-treated hemp fibres.
Design/methodology/approach
The composites were tested for strengths under tensile, flexural, impact and shear loadings, and the water absorption characteristics were also observed. The finite element analysis (FEA) was carried out to analyse the elastic behaviour of the composites and predict the strength by using ANSYS 15.0.
Findings
From the experimental results, it is observed that the hybrid composites can withstand the maximum tensile strength of 61.4 MPa, flexural strength of 122.4 MPa, impact strength of 4.2 J/mm2 and shear strength of 25.5 MPa. From the FEA results, it is found that the maximum stress during tensile, flexural and impact loading is 47.5, 2.1 and 1.03 MPa, respectively.
Originality/value
The results of the untreated and alkaline-treated hemp-carbon fibre composites were compared and found that the alkaline-treated composites perform better in terms of mechanical properties. Then, the ANSYS-predicted values were compared with the experimental results, and it was found that there is a high correlation occurs between the untreated and alkali-treated hemp-carbon fibre composites. The internal structure of the broken surfaces of the composite samples was analysed using a scanning electron microscopy (SEM) analysis.

Abstract
Purpose
We aimed to determine how remote management support (MS) practices and staff diversity influenced employee performance (EP) within the digital workplace (DW) during the COVID-19 pandemic. The article highlights the challenges managers face in achieving EP in the DW compared to traditional work environments.
Design/methodology/approach
We developed a theoretical model (MS→DW→EP) and tested it based on the computer-assisted web interview (CAWI) conducted in mid-2022. Factors of primary, secondary and organizational diversity moderated the relationship between the variables. We purposely selected a sample of 1,000 respondents with remote working experience.
Findings
The results show that the DW partially mediates the relationship between MS and EP. The greater the uncertainty in managing people, the more flexibility, trust and job satisfaction required in the DW to achieve EP. Organizational diversity influenced the model more (i.e. teamwork vs individual work) than the primary and secondary diversity (i.e. gender and education).
Research limitations/implications
Although the sample size was large, we cannot consider it statistically representative.
Practical implications
Zoomers and Millennials reflect full mediation in the model that supports EP.
Social implications
Broader work autonomy, smaller organizations and teams as well as hybrid work arrangements, reduce the necessity for in-person meetings with superiors.
Originality/value
Supervisors had to reduce control over the DW while expanding organizational citizenship behavior (OCB) to enhance job satisfaction and thus ensure the expected EP during the pandemic. We may consider allowing an employee to postpone work as a new managerial activity within MS.

Abstract
Purpose
The purpose of the study is twofold. First, it aims to analyse the impact of green human resource management (GHRM) on green employee creativity. Second, it further explores the mediating role of personal moral norms between GHRM and green employee creativity.
Design/methodology/approach
Through multi-source and multi-level analysis, data was collected from 46 managers and 315 employees to investigate the role of personal moral norms in GHRM and green employee creativity. For data analysis, multi-level structural equation modelling was applied using Mplus software version 8.6.
Findings
Positive and significant effects were observed between GHRM, personal moral norms and green employee creativity. However, personal moral norms partially mediated the relationship between GHRM and green employee creativity.
Originality/value
The study is first in itself to explore the interplay between the variables in a multi-level manner. The present study aims at addressing the urgent call by the United Nations regarding Sustainable Development Goals (SDGs) for three key SDGs, focussing on decent work and economic growth (SDG 8), boosting industry, innovation and infrastructure (SDG 9) and supporting climate action (SDG 12).

Abstract
Purpose
Based on attribute research in marketing, importance-performance analysis (IPA) provides a useful analogy to examine employer branding concepts. The purpose of this paper is to use IPA to evaluate employees’ perceptions of important employer value proposition (EVP) attributes and their corresponding psychological contract fulfillment scores. IPA is applied to 40 EVP attributes and their corresponding EVP dimensions – “Economic Value”, “Development Value”, “Social Value”, “Work Value” and “Employer Reputation.” Further, the paper examines the difference between highly engaged and less engaged employees in their relationship to importance and fulfillment of the five EVP dimensions.
Design/methodology/approach
Data were drawn from information technology-business process management employees (n=520) in India through a questionnaire survey. The IPA matrix was used to plot the importance and fulfillment scores. Independent samples t-test was used to assess the difference between high and low engagement scores.
Findings
The results indicate that several EVP attributes fall within the “Concentrate Here” quadrant that requires more focus. With respect to EVP dimensions, social value needs focus; economic value received “Low Priority”; and work value and employer reputation are identified as “Potential Overkill.” The findings also suggest that, organizations should engage employees across all dimensions, by both prioritizing and fulfilling their obligations promptly.
Practical implications
The study highlights the need for HR practitioners and academicians to draw insights from attribute research in marketing to effectively devise the employer branding strategy of individual organizations.
Originality/value
This paper is the first of its kind to apply IPA to EVP attributes, which contributes to the growing literature on employer branding.
