Abstract
Purpose
This paper aims to develop a real-time pothole detection system to improve mapping, localization and path planning, reducing vehicle instability and accident risks. Efficient mapping, accurate localization and optimal path planning stand as prerequisites to realizing accident-free navigation. Despite their significance, existing literature often overlooks the real-time detection of potholes, which poses a considerable risk, particularly during nighttime operations. Potholes contribute to vehicle imbalance, trajectory tracking errors, abrupt braking, wheel skidding, jerking and steering overshoot, all of which can lead to accidents.
Design/methodology/approach
Unmanned vehicles constitute a critical domain within robotics research, necessitating reliable autonomous navigation for their optimal functioning. This research paper addresses the gap in current methodologies by leveraging a Convolutional Neural Network (CNN)-based approach to detect potholes, facilitating the generation of an efficient environmental map. Furthermore, a hybrid solution is proposed, integrating an improved Ant Colony Optimization (ACO) algorithm with modified Bezier techniques, complementing the CNN approach for accident-free and time-efficient unmanned vehicle navigation. The conventional Bezier technique is enhanced by incorporating new control points near sharp turns, mitigating rapid trajectory convergence and ensuring collision-free paths.
Findings
The hybrid solution, combining CNN with path smoothing techniques, is rigorously tested in various real-time scenarios. Experimental results demonstrate that the proposed technique achieves a 100% reduction in collisions in favorable conditions, a 4.5% decrease in path length, a 100% reduction in sharp turns and a significant 23.31% reduction in total time lag compared to state-of-the-art techniques such as conventional ACO, ACO+ Bezier and ACO+ midpoint Bezier, Improved ACO, hybrid ACO+ A*.
Originality/value
The proposed technique provides a proficient solution in the field of unmanned vehicles for accident-free time efficient navigation in an unstructured environment.

Case overview/synopsis
In the competitive world of India’s quick-service restaurants industry, Shilpa Bhatt Bahuguna, the young entrepreneur behind “Pizza Italia,” aimed to secure the top spot in Uttarakhand. Despite facing setbacks by closing six out of the eight outlets during the COVID-19 pandemic, Bahuguna’s focus on product quality and localization had garnered word-of-mouth publicity for her brand. Now, with a limited budget for promotions, Bahuguna sought below-the-line strategies to ensure profitability and success for new outlets. Her determination to establish Pizza Italia as an indigenous brand and her plans for global expansion through franchising reflected her vision for growth and impact in the market. With her entrepreneurial spirit, Bahuguna remained poised to achieve even greater success in the future. Bahuguna aimed to leverage her product quality and word-of-mouth promotion to capture the market. She planned to expand her brand globally and open new outlets in Uttarakhand and London. However, Bahuguna was challenged to promote her brand on a limited budget, favoring “below-the-line” strategies.

Abstract
Purpose
The purpose of the study is to investigate the long-run and short-run dynamic relationship between crude oil prices and the movement of Sensex for the period of 2000–2018.
Design/methodology/approach
The study uses the augmented Dickey–Fuller test for the presence of unit root, Johansen cointegration test for estimating the cointegration among the variables. Further, in the case of no cointegration found, the study employed the vector autoregression (VAR) model to estimate the long-run relationship and the Granger causality/Wald test for short-run relationship. The study also conducted tests for the prerequisites of the model: serial correlation, heteroskedasticity and normality of data.
Findings
The study found that both the variables, crude oil prices and Sensex are integrated of order 1, that is, I (1), and there is no cointegration between them. Further, the results proliferated from the VAR model unfold the marked effect of previous month crude oil prices (lag 1) on the movement of Indian stock market represented by Sensex considered as the benchmark index. Furthermore, VAR–Granger causality/block exogeneity Wald tests results indicated that there is a causal relationship between the crude oil prices and Sensex under the VAR environment. The model does not have any serial correlation and heteroskedasticity indicating toward the unbiased and robust estimates.
Research limitations/implications
The study is conducted till the year 2018, and data for the present period (post-2018) is excluded due to ongoing trade issues between the USA and oil-exporting countries such as Iran. The current COVID-19 outbreak has also put serious issues. Due to limited time and availability of standardized data, researchers have considered Sensex as equity index only, but for more generalized research outcome few other equity indexes could have been taken for study.
Originality/value
The study is completely original in nature and is an extensive study of the relationship between the crude oil price and Indian stock market with reference to causality between the variables.

Abstract
Purpose
The Internet of Things (IoT), as one of the new digital technologies, has created wide applications in various industries, and one of the most influential industries of this technology is the transportation industry. By integrating the IoT with the transportation industry, there will be dramatic changes in the industry, and it will provide many entrepreneurial opportunities for entrepreneurs to develop new businesses. Opportunity identification is at the heart of the entrepreneurial process, and entrepreneurs identify innovative goods or services to enter a new market by identifying, evaluating, and exploiting opportunities. Despite the desire of transportation managers to invest in the IoT and the increase in research in this area, limited research has focused on IoT-based entrepreneurial opportunities in the transportation industry. Therefore, the present study aims to identify IoT-based entrepreneurial opportunities in the transportation industry and examine their importance.
Design/methodology/approach
To achieve the research objective, the authors applied a mixed approach. First, adapting the lens of the industry value chain theory, a comprehensive literature review, besides a qualitative approach including semi-structured interviews with experts and thematic analysis, was conducted to identify the entrepreneurial opportunities. The identified opportunities were confirmed in the second stage using a quantitative survey method, including the Student t-test and factor analysis. Finally, the identified opportunities were weighted and ranked using the best worst method (BWM).
Findings
Entrepreneurial opportunities are classified into five main categories, including “smart vehicles”, “business partners/smart transportation supply side”, “supporting services”, “infrastructures”, and “smart transport management and control”. The infrastructures group of opportunities ranked the highest amongst the identified groups.
Originality/value
This study adds to the digital entrepreneurship opportunity recognition literature by addressing opportunities in a smart industry propelled by digital technologies, including developing new products or new applications of the available technologies. Additionally, inspired by the industry value chain theory, this article develops a framework including various digital entrepreneurial opportunity networks which are necessary to add value to any industry and, thus, could be applied by entrepreneurs to recognize opportunities for new intermediaries to enter other digital-based industries. Finally, the present study identifies the IoT-based entrepreneurial opportunities in the smart transportation industry and prioritizes them, providing practical insights regarding the creation of entrepreneurial ecosystems in the field of smart transportation for entrepreneurs and policymakers.

Abstract
Purpose
This research investigates the barriers for Complementary and Alternative Medicine (CAM) adoption among the patients in India. Despite the established role of CAM in the Indian healthcare system for several years, the WHO (WHO) reports limited adoption of these therapies among Indian patients. This study investigates the key barriers toward wider CAM use within the Indian context.
Design/methodology/approach
This study used a combined interpretive structural modeling (ISM)-MICMAC approach to identify barriers to CAM usage. In the first phase, a comprehensive literature review was conducted to understand the barriers. Subsequently, experts in the Indian healthcare system were identified and interviewed to capture the contextual intricacies of these barriers within the Indian context.
Findings
The study identified ten key barriers to CAM adoption through ISM. A hierarchical model was developed to understand the relationships and interactions among these barriers, revealing their linkages. A MICMAC chart was created to determine the driving and dependent power of the barriers, categorizing them as dependent barriers, linkage barriers or independent barriers. The House of CAM framework was then derived from the ISM-MICMAC analysis, providing a structured, sequential approach for CAM adoption.
Practical implications
The awareness of the potential benefits and usage of CAM is significantly low among Indian patients. There is a pressing need to investigate and systematically conceptualize the barriers to CAM adoption. This research provides valuable insights for policymakers, insurers, practitioners of alternative and complementary medicine, multi-specialty hospitals offering CAM services and regulatory bodies. Understanding these barriers will enable these stakeholders to develop and implement strategies that effectively address these issues.
Originality/value
This research makes substantial contributions to the understanding of barriers to the adoption of CAM. Through a comprehensive investigation, the study introduces the House of CAM framework developed using ISM-MICMAC analysis, providing a strategic approach for targeted intervention against identified barriers.
