Abstract

Purpose

This paper aims to present an approach for calibrating the numerical models of dynamical systems that have spatially localized nonlinear components. The approach implements the extended constitutive relation error (ECRE) method using multi-harmonic coefficients and is conceived to separate the errors in the representation of the global, linear and local, nonlinear components of the dynamical system through a two-step process.

Design/methodology/approach

The first step focuses on the system’s predominantly linear dynamic response under a low magnitude periodic excitation. In this step, the discrepancy between measured and predicted multi-harmonic coefficients is calculated in terms of residual energy. This residual energy is in turn used to spatially locate errors in the model, through which one can identify the erroneous model inputs which govern the linear behavior that need to be calibrated. The second step involves measuring the system’s nonlinear dynamic response under a high magnitude periodic excitation. In this step, the response measurements under both low and high magnitude excitation are used to iteratively calibrate the identified linear and nonlinear input parameters.

Findings

When model error is present in both linear and nonlinear components, the proposed iterative combined multi-harmonic balance method (MHB)-ECRE calibration approach has shown superiority to the conventional MHB-ECRE method, while providing more reliable calibration results of the nonlinear parameter with less dependency on a priori knowledge of the associated linear system.

Originality/value

This two-step process is advantageous as it reduces the confounding effects of the uncertain model parameters associated with the linear and locally nonlinear components of the system.

Abstract

Purpose

This paper aims to focus on the assessment of the ability of computer models with imperfect functional forms and uncertain input parameters to represent reality.

Design/methodology/approach

In this assessment, both the agreement between a model’s predictions and available experiments and the robustness of this agreement to uncertainty have been evaluated. The concept of satisfying boundaries to represent input parameter sets that yield model predictions with acceptable fidelity to observed experiments has been introduced.

Findings

Satisfying boundaries provide several useful indicators for model assessment, and when calculated for varying fidelity thresholds and input parameter uncertainties, reveal the trade-off between the robustness to uncertainty in model parameters, the threshold for satisfactory fidelity and the probability of satisfying the given fidelity threshold. Using a controlled case-study example, important modeling decisions such as acceptable level of uncertainty, fidelity requirements and resource allocation for additional experiments are shown.

Originality/value

Traditional methods of model assessment are solely based on fidelity to experiments, leading to a single parameter set that is considered fidelity-optimal, which essentially represents the values which yield the optimal compensation between various sources of errors and uncertainties. Rather than maximizing fidelity, this study advocates for basing model assessment on the model’s ability to satisfy a required fidelity (or error tolerance). Evaluating the trade-off between error tolerance, parameter uncertainty and probability of satisfying this predefined error threshold provides us with a powerful tool for model assessment and resource allocation.

Abstract

Purpose

This paper aims to recommend an approach which can help ensure the fast-track career progression of employees.

Design/methodology/approach

The paper uses data from a larger study on leadership development practices in the context of rapid growth organizations. This was based on semi-structured interviews with 43 senior managers from medium-sized organizations in the Indian software services industry.

Findings

The study suggests that many respondents, who were from a pool of fast-track employees, had experienced some kind of success early on in their careers or particular roles. This was due to various reasons such as exciting opportunities, proximity to top management, a supportive boss, or challenging assignments.

Originality/value

The paper can be of immense help to organizations by helping them to plan their induction and onboarding activities more effectively, so as to provide new recruits with early success experience of some sort, which in turn will help them to fast-track their career growth.

Abstract

Purpose

This paper highlights the role of an individual’s early life experiences (formative years’ experiences) in the learning and development (L&D) journey of their careers. Hence, it is useful for the individual managers as well as organizations to better understand and improve the effectiveness of their L&D processes.

Design/methodology/approach

The paper draws insights from a small subset of the data collected as a part of a larger study on leadership development processes in the context of medium-sized rapid growth organizations in the Indian software services industry.

Findings

The respondents, i.e. senior managers in the software services firms, shared some of their experiences in their formative years (family/school/university/career) which they felt had a huge impact on the way their careers had shaped up. These stories spanned across diverse experiences like values instilled in childhood by parents/grandparents, influence of schoolteachers, friends and peers during growth years, academic performance during college/university days, and successful or positive experiences during early career years.

Originality/value

The paper can be useful to managers in their career development, as well as to organizations in making their L&D processes more effective. It provides a more nuanced understanding of how the experiences in formative years can help improve one’s development and performance in organizations; while the organizations allow, and create, conducive environment for the managers to harness these experiences gained early in life.

Abstract

Purpose

The purpose of the study is to examine how operating efficiencies from incentive alignment compensate for rent extraction in family firms. The author asks whether ownership (1) improves operating efficiencies to increase firm value, (2) positively affects related-party transactions (RPTs), or (3) destroys firm value. Finally, the author assesses whether the incentive effect dominates the entrenchment effect.

Design/methodology/approach

This study employs a panel of 333 listed family firms (and 185 nonfamily firms) and handles endogeneity using a dynamic panel system GMM and panel VAR.

Findings

Ownership decreases discretionary expenses and increases asset utilization to add firm value. The efficiency gains generate more value in family firms, especially majority-held ones, than in nonmajority ones. However, ownership is also related to increased RPTs (especially dubious loans/guarantees), reducing firm value. RPTs destroy value more severely in the family (or group) firms than in nonfamily (nongroup) firms. It could be why ownership's positive impact on value is lower in family firms than in nonfamily firms. Overall, the incentive effect dominates the entrenchment effect and is robust to controlling private benefits of control in the dynamic ownership-value model.

Research limitations/implications

(1) A family firm's ownership may not be optimal. (2) The firm's long-term commitment as a dynasty limits the scale of expropriation yet sustains impetus for long-term value creation. The paradox partly explains why large family holdings and firm-specific investments endure over generations. (3) This way, large ownership substitutes weak investor protection in India despite tunneling as skin in the game provides necessary investor confidence. (4) Future studies can examine whether extraction varies with family generations and how family characteristics affect the incentive effects.

Practical implications

(1) Concentrated ownership may not be a wrong policy choice in emerging markets to draw firm-specific investments. (2) Investors, auditors, or creditors must pay closer attention to loans/guarantees. (3) More vigorous enforcement, auditor scrutiny, and board oversight are needed.

Social implications

Family firms are not necessarily a bad organization type that destroys investor wealth. They can be valuably efficient due to their ownership and wealth concentration, and frugality. They matter in the economic growth of a developing market like India.

Originality/value

(1) Extends ownership-performance research to family firms and shows that although ownership facilitates tunneling, the incentive effect dominates; (2) family ownership is not impacted by firm value; (3) family ownership levels reduce discretionary expenses and increase asset utilization to create added value, especially in majority-held family firms; (4) RPTs and loans/guarantees increase with ownership; (5) value erosion from RPTs is higher in family (group) firms than in other firms.

Abstract

Purpose: Progression is an unpreventable reality of presence, and banking is no exclusion. Cash transformers and moneylenders from times gone past are great agents today. Cash held in trust became store taking, and money advancing became credit making; over an extended time, banks transformed into a need, and the occupation of banks, transformed into a critical piece of monetary reality. Banks’ turn of events and headway has been mind-boggling, with the latest frenzy being intuitive media banking. The chapter additionally framed the amazing open doors and dangers for banks because of the presentation of innovations and how banks are making the most of the open doors and endeavouring to cure the risks. The financial area in India is a lifesaver for the country. Indian banks could become the fifth most prominent on earth by 2020 and the third most prominent by 2025.

Methodology: This study has given auxiliary information. Furthermore, it’s gathered from the holding bank of India concerning utilisation by various banks. Which utilised graphic review including mean mode middle.

Finding: After the review, we find that sight, sound, and green banking have become fantastic assets for the baking area. During COVID-19, the utilisation of mixed media expanded in contrast to a year ago.

Significance: The review featured sight and sound and green banking sealed spine in COVID -19 and is utilised expanded after this pandemic.

Abstract

Purpose

The purpose of this study is to explore how past and future temporal focus of CEOs in the hospitality industry influence their intention to invest in metaverse technology and the underlying mechanism under boundary conditions of perceived competitive pressure.

Design/methodology/approach

This multi-informant study collected data over three waves from a sample of 235 CEOs and their subordinates in India’s hospitality industry. A PLS-SEM was applied to the study data. Further, the study also used phenomenological interviews to capture CEOs’ perspectives on the study’s conceptual model.

Findings

Findings suggest that the past temporal focus of CEOs decreases technology orientation, and future temporal focus increases the technology orientation of firms, consequently impacting the intention to invest in the metaverse. CEOs’ perceived competitive pressure moderates the mediating relationship, such that the negative impact of past temporal focus on technology orientation is decreased and that of future temporal focus on the CEO is increased.

Research limitations/implications

By exploring the role of a CEO’s past and future temporal focus on influencing technology orientation and, hence, adoption of new technology, the study extends upper-echelon theory to the field of metaverse adoption in the hospitality industry and responds to scholars’ calls to explore the industry’s technology adoption from the lens of the upper echelon.

Practical implications

The study has significant implications for the success of the adoption of metaverse technology in the hospitality industry. Findings imply that the board members should encourage CEOs to have future temporal focus.

Originality/value

The study provides novel insights into the adoption of metaverse technology by the hospitality industry, where CEO attributes such as their temporal focus influence intention to invest in metaverse.

Abstract

Purpose

The dynamics of the competitive performance of the small medium firms is an evolving field of research in the developing countries like India. The influence of the innovation on the competitive performance of the firms is still an evolving area in India. This paper aims to explore the influence of the innovation on the competitive performance. The study is based upon the agro-food processing industry of the Jammu and Kashmir state of India.

Design/methodology/approach

The paper is based upon the exploratory design. It uses quantitative as well as qualitative method for the firm level analysis of competitiveness. The aggregate index method has been used to construct the innovation competence and total competitive performance index. The regression analysis is used for describing the model based upon the primary data.

Findings

The results of the study provide for a significant relationship between the innovation competence and firm level competitiveness. It describes the position of the agro-food processing firms under study with respect to the innovation competence index score and total competitiveness performance index.

Research limitations/implications

The paper provides for the managerial implications of strategically incubating the innovation-based competence for the firms in specific geographical areas. The policy implications in terms of developing specific clusters and incubators for incremental and radical innovations can be derived, in regional economies.

Originality/value

The paper discusses the issue of interaction of innovation competence and firm level competitiveness of the agro-food processing industry, which is dynamic, specifically in the developing states. The paper discussed unique methodology of using aggregate index method for defining the innovation competence and competitiveness for the firms where the consistency of data is a major issue for such a complex phenomenon.

Abstract

Purpose

The purpose of this study is to explore how institutional trust, frugality and materialism motivate consumers’ unethical behavior.

Design/methodology/approach

The authors conducted the study in two phases – qualitative and quantitative. In the qualitative phase through a content analysis of semi-structured interviews, a list of unethical activities was obtained. In the quantitative phase, a questionnaire was developed, which had questions related to the unethical activities. Data collection for the quantitative phase was achieved through mall intercept surveys. The collected data were subjected to exploratory factor analysis, confirmatory factor analysis and multivariate regression analysis.

Findings

Poor institutional environment, frugal attitude and materialistic values motivate consumers from an emerging economy to indulge in unethical acts some of which were not explored before such as booking a cab but not boarding or stealing electricity.

Originality/value

Research evidence on unethical consumer behavior is lacking from emerging markets. Furthermore, extant studies have used mainly national culture models to explore unethical behavior, and finally, the role of institutional trust and frugality has not been explored in previous studies. The present study tries to fill these gaps by considering these elements as the cornerstone of this study.
