Abstract
Purpose
This paper aims to propose a system to acquire images automatically for digital reconstruction of heritage artifacts using a six-degree of freedom industrial manipulator.
Design/methodology/approach
A virtual environment is created using Robot Studio® software to integrate the trajectory and differential motion of the robot manipulator and the motion of camera while acquiring images. A new area similarity matrix method is proposed to reduce the number of images required for digital reconstruction using Autodesk Recap® software. Real-time experiments have been performed using objects such as minion, ultimaker robot and cube. Evaluation of the digital reconstruction is conducted using the contour area matching method.
Findings
The number of images required for reconstruction based on area similarity matrix method is reduced to 63 per cent when compared with the random selection method. Quality parameters such as surface area, volume, number of defect holes, vertices and faces are enhanced for the proposed method.
Research limitations/implications
Digital reconstruction of large-sized heritage artifacts cannot be performed in this setup. But this can be overcome by fixing the manipulator on a mobile platform or overhead crane. This paper does not discuss the reconstruction of partially damaged heritage artifacts, which could be accomplished based on deep learning techniques.
Practical implications
Using this approach, off-the-shelf heritage artifacts and large-scale objects can be reconstructed digitally with a minimum number of images and without compromising the quality of original models.
Originality/value
To the best of the authors’ knowledge, area similarity-based approach in 3D digital reconstruction by coupling the kinematics of an industrial manipulator and camera is proposed for the first time. A fully automated digital reconstruction technology to preserve valuable heritage artifacts has been developed. It also highlights the space constraints of the industrial manipulator in digital reconstruction.

Abstract
Purpose
The purpose of this paper is to review the key literature pertaining to consumption during the colonial period in India, broadly covering the time period from the early nineteenth century to the middle of the twentieth century. The review shows the prominent themes and patterns that help us understand colonial Indian consumers’ encounter with Western products and institutions.
Design/methodology/approach
The paper is a review of historical research papers and papers pertaining to the colonial period in India.
Findings
British colonialism introduced new products, institutions and ways of living into India, which were negotiated with and contested by Indian consumers and intellectuals. These new products and practices were not seamlessly adopted into the Indian context. Rather, they were appropriated into existing social structures determined by caste, gender and religion. The tensions produced by such negotiations and contestations fed Indian resistance to colonialism, culminating in British withdrawal from India.
Originality/value
Historical research pertaining to marketing in the Indian context is scarce. Moreover, there are few reviews which outline the important consumption practices and changes pertaining to the colonial period. The findings of this review will be of use to researchers and students of history, marketing and cultural studies.

Abstract
Purpose
This paper explores the different open science policy effects on the knowledge generation process of researchers in basic sciences: biology, chemistry and physics.
Design/methodology/approach
This paper uses a qualitative methodology with a content analysis approach. It uses seventeen semi-directed interviews.
Findings
The main perceived effect of open science is access to research inputs, with open access, open research data and code reuse as primary sources. Another issue is the increase of collaboration with other colleagues in terms of the ability to collaborate faster and encouraging the exchange of ideas. However, this benefit does not translate to the division of labor in large transnational teams. Time spent on tasks like cleaning up data and code, scooping and other ethical issues are unfavorable aspects noted.
Practical implications
Policymakers could use this study to enhance current open science policies in the countries.
Originality/value
This study analyzes the perspectives of basic sciences researchers from two countries about open science policies. The main conclusion is the fact that open science policies should focus on the research process itself – rather than research outputs – in order to effectively tackle inequalities in science.
