Abstract
Purpose
This study aims to investigate the shopping behaviour of consumers, mainly in fashion apparels, and intends to understand consumer buying patterns in Indian context. The study was designed to determine the level of consumer's sense of belonging towards apparel shopping by applying the concept of self-congruence.
Design/methodology/approach
The study used variance-based partial least squares structural equational modelling (PLS-SEM) on a cross-sectional study conducted on 569 consumers. The study was conducted by using questionnaire to collect the responses from the central zone of India. The results support most of the projected hypotheses.
Findings
The study focused on the shopping behaviour of consumer such as self-congruence, impulse buying, hedonic values and consumer satisfaction. The results of the study highlight the association of constructs and analysed the mediation relation of hedonic and impulse buying constructs. The results revealed a positive association among the constructs and also found a partial mediation effect in their relation with constructs.
Research limitations/implications
The findings are outcomes of an empirical study conducted in the fashion apparel industry of India based on the sample set of urban consumers. The study is restricted to the direct and indirect relationship of constructs. Further, research can examine by using moderating constructs like demographic factors (gender, age, income, etc.) and other shopping behaviours (like brand loyalty, brand love, brand attachment) for more clarity in results. Moreover, the study limited is with fashion apparel, whereas there are many categories in the fashion industry like accessories, perfumes, cosmetic products, footwear and also other products industry.
Practical implications
The study provided valuable inputs to the literature of marketing where self-congruence affects consumer shopping behaviour such as impulse buying, hedonic values and consumer satisfaction. The study proposes a practical approach that can help the marketing professionals and product developers to have a deep understanding about consumer shopping behaviour for facilitating consumer-oriented goods in the Indian fashion industry.
Originality/value
This is one of the first studies in the fashion industry to test the association of self-congruence with hedonic value and consumer satisfaction. This relation is not tested in context of fashion apparel. Additionally, this study also examined the mediating effect of hedonic value and impulse buying in relation with self-congruence and consumer satisfaction in the Indian context.

Abstract
Purpose
This study aims to verify the significance of Andersen (2008) corporate risk management (CRM) framework in Asian emerging markets (AEMs) to control firm risk and improve firm performance.
Design/methodology/approach
The cross-sectional analyses are performed on a sample of 4,609 firms across nine Asian emerging countries using 2SLS estimation technique.
Findings
The empirical findings show that the adoption of CRM not only enhances firm performance by increasing the firm ability to capitalize on the market opportunity but also plays a significant role in reducing firm risk. The findings of this study assert that by institutionalizing risk management practices into an integrated CRM framework, the firm can reap multiple benefits by maintaining better contractual agreements and strategic partnerships with key stakeholders.
Originality/value
The study shifts the focus of CRM away from Western countries toward AEMs, which has been afflicted by high risks and uncertainties. The effectiveness of CRM against firm risk is established by dividing firm risk into firm-specific risk and systematic risk. Furthermore, this study also establishes that CRM not only leads to high returns but also reduces firm operational and production costs. Overall, the study provides a compelling argument to implement CRM for improving organizational performance and managing risks in a strategic and integrated manner. The findings are also relevant to risk management practitioners, as well as to academicians interested in the broader fields of corporate finance and strategy.

This study aims to extend Bowman's risk–return paradox to Asian emerging markets and explain its causes under the prospect theory.
Abstract
Purpose
This study aims to extend Bowman's risk–return paradox to Asian emerging markets and explain its causes under the prospect theory.
Design/methodology/approach
The study is conducted on a cross-sectional sample of 4,609 firms across nine Asian emerging countries. The two stage least squares (2SLS) estimation technique is used to evaluate the three objectives of the study, i.e. Bowman's risk–return paradox, significance of firm-specific risk and prospect theory explanation of Bowman's paradox.
Findings
The authors challenge the two basic financial economics arguments that higher risk is rewarded with higher return, and firm-specific risk is diversifiable. The empirical findings confirm the negative impact of firm-specific and systematic risk on firm return, thus, corroborates the Bowman's explanation of risk–return trade-off. However, the authors did not find empirical evidence to support prospect theory's explanations of Bowman’s paradox in Asian emerging markets.
Originality/value
A holistic approach is adopted to analyze the various aspects of Bowman's paradox and its causes for the same time period, variables and sample. The authors also rectified several methodological limitations observed in previous studies, i.e. the use of same proxies for firm return and risk, endogeneity and survivorship issues. Furthermore, the findings of this study will enable managers to formulate critical viewpoint on firm-specific risk and systematic risk and take informed strategic decisions regarding optimum utilization of their firm's key resources in Asian emerging markets.

Abstract
Purpose
Most of the total quality management (TQM) programmes implemented in the printing industry fail to produce the intended benefit, because of the view that quality achievement is workers responsibility. The purpose of this paper is to examine the role management plays in the implementation of TQM programme in the Ghanaian printing firms.
Design/methodology/approach
The study employed mixed method in gathering relevant data. A cross-sectional survey questionnaire was given to 145 managers of registered members of Ghana Printers and Paper Converters Association, Southern Sector to assess the role management plays in TQM programme. Key informant interview was conducted among ten randomly selected production managers of printing firms to complement the survey data.
Findings
The study finds out that organizational performance (OP) is not significantly influenced by the level of commitment of top management in a printing organization. Rather OP is greatly influenced and determined by leadership styles of management and the quality policy which guides printing operations.
Practical implications
The Ghanaian printing industry can ensure better OP by considering the kind of leadership style exhibited in the firm and develop quality policy to guides printing operations and activities. No matter the level of commitment of organizational resources, if it is not back by a good leadership style and a quality policy, TQM initiative will not yield the intended result.
Originality/value
The study presents managerial issues and practices critical for successful TQM programme in the Ghanaian printing industry.

Abstract
Purpose
The purpose of this study is to explore the effects of aerospike and hemispherical aerodisks on flow characteristics and drag reduction in supersonic flow over a blunt body. Specifically, the study aims to analyze the impact of varying the length of the cylindrical rod in the aerospike (ranging from 0.5 to 2.0 times the diameter of the blunt body) and the diameter of the hemispherical disk (ranging from 0.25 to 0.75 times the blunt body diameter). CFD simulations were conducted at a supersonic Mach number of 2 and a Reynolds number of 2.79 × 106.
Design/methodology/approach
ICEM CFD and ANSYS CFX solver were used to generate the three-dimensional flow along with its structures. The flow structure and drag coefficient were computed using Reynolds-averaged Navier–Stokes equation model. The drag reduction mechanism was also explained using the idea of dividing streamline and density contour. The performance of the aero spike length and the effect of aero disk size on the drag are investigated.
Findings
The separating shock is located in front of the blunt body, forming an effective conical shape that reduces the pressure drag acting on the blunt body. It was observed that extending the length of the spike beyond a specific critical point did not impact the flow field characteristics and had no further influence on the enhanced performance. The optimal combination of disk and spike length was determined, resulting in a substantial reduction in drag through the introduction of the aerospike and disk.
Research limitations/implications
To predict the accurate results of drag and to reduce the simulation time, a hexa grid with finer mesh structure was adopted in the simulation.
Practical implications
The blunt nose structures are primarily employed in the design of rockets, missiles, and re-entry capsules to withstand higher aerodynamic loads and aerodynamic heating.
Originality/value
For the optimized size of the aero spike, aero disk is also optimized to use the benefits of both.

Abstract
Purpose
The purpose of this paper is to initiate researches in the direction of integrating knowledge management (KM) principles with ISO 9001:2008 Supported Quality System and motivate the practitioners to implement such integrated system in real-time practice.
Design/methodology/approach
The principles of KM were integrated with the five major clauses of ISO 9001:2000 standard. After designing this integrated system, it was subjected to peripheral implementation study in a government-managed company situated in India. The knowledge portal required for maintaining this integrated system was also developed.
Findings
ISO 9001:2008 and ISO 9001:2000 standards rest on the same process-based quality system model which is comprised of five major clauses. Hence, the integrated system proposed in this paper can be utilized by the contemporary organizations to infuse KM principles in ISO 9001:2008 based quality system.
Research limitations/implications
Though the integrated system designed in this research could not be implemented in a full-fledged manner, the experiences gained have been useful to indicate the future direction of research and practice for integrating KM principles with ISO 9001:2008 Supported Quality System.
Practical implications
A roadmap has been evolved to guide the practitioners to implement Knowledge Managed ISO 9001:2008 Supported Quality System.
Originality value
No researcher or practitioner has so far contributed a model integrating the process-based quality system incorporated in ISO 9001:2000 and ISO 9001:2008 standards with KM principles. As this gap is filled in this paper, the contributions of this paper are valuable to both researchers and practitioners.

Abstract
Purpose
An experimental investigation of hemispherical forebody interaction effects on the drag coefficient of a D-shaped model is carried out for three-dimensional flow in the subcritical range of Reynolds number 1 × 105 ≤ Re ≤ 1.8 × 105. To study the interaction effect, hemispherical shapes of various sizes are attached to the upriver of the D-shaped bluff body model. The diameter of the hemisphere (b1) varied from 0.25 to 0.75 times the diameter of the D-shaped model (b2) and its gap from the D-shaped model (g/b2) ranged from 0.25 to 1.75 b2.
Design/methodology/approach
The experiments were carried out in a low-speed open-circuit closed jet wind tunnel with test section dimensions of 1.2 × 0.9 × 1.8 m (W × H × L) capable of generating maximum velocity up to 45 m/s. The wind tunnel is equipped with a driving unit which has a 175-hp motor with three propellers controlled by a 160-kW inverter drive. Drag force is measured with an internal six-component balance with the help of the Spider 3013 E-pro data acquisition system.
Findings
The wind tunnel results show that the hemispherical forebody has a diameter ratio of 0.75 with a gap ratio of 0.25, resulting in a maximum drag reduction of 67%.
Research limitations/implications
The turbulence intensity of the wind tunnel is about 5.6% at a velocity of 18 m/s. The uncertainty in the velocity and the drag coefficient measurement are about ±1.5 and ±2.83 %, respectively. The maximum error in the geometric model is about ±1.33 %.
ractical implications
The results from the research work are helpful in choosing the optimum spacing of road vehicles, especially truck–trailer and launch vehicle applications.
Social implications
Drag reduction of road vehicle resulting less fuel consumption as well as less pollution to the environment. For instance, tractor trailer experiencing approximately 45% of aerodynamics drag is due to front part of the vehicle. The other contributors are 30% due to trailer base and 25% is due to under body flow. Nearly 65% of energy was spent to overcome the aerodynamic drag, when the vehicle is traveling at the average of 70 kmph (Seifert 2008 and Doyle 2008).
Originality/value
The benefits of placing the forebody in front of the main body will have a strong influence on reducing fuel consumption.
