Abstract

Purpose

This paper aims to describe the control software of a novel manufacturing system called plasma-assisted bio-extrusion system (PABS), designed to produce complex multi-material and functionally graded scaffolds for tissue engineering applications. This fabrication system combines multiple pressure-assisted and screw-assisted printing heads and plasma jets. Control software allows the users to create single or multi-material constructs with uniform pore size or pore size gradients by changing the operation parameters, such as geometric parameters, lay-down pattern, filament distance, feed rate and layer thickness, and to produce functional graded scaffolds with different layer-by-layer coating/surface modification strategies by using the plasma modification system.

Design/methodology/approach

MATLAB GUI is used to develop the software, including the design of the user interface and the implementation of all mathematical programing for both multi-extrusion and plasma modification systems.

Findings

Based on the user definition, G programing codes are generated, enabling full integration and synchronization with the hardware of PABS. Single, multi-material and functionally graded scaffolds can be obtained by manipulating different materials, scaffold designs and processing parameters. The software is easy to use, allowing the efficient control of the PABS even for the fabrication of complex scaffolds.

Originality/value

This paper introduces a novel additive manufacturing system for tissue engineering applications describing in detail the software developed to control the system. This new fabrication system represents a step forward regarding the current state-of-the-art technology in the field of biomanufacturing, enabling the design and fabrication of more effective scaffolds matching the mechanical and surface characteristics of the surrounding tissue and enabling the incorporation of high number of cells uniformly distributed and the introduction of multiple cell types with positional specificity.

Abstract

Asserts that foreign multinational corporations (MNCs) investing in or expanding business operations in China, South and Southeast Asia often find themselves sparring with local business groups. Draws on research and experiences with firms in the region in order to enhance understandings of competitive dealings with two business networks that dominate the Southeast Asian economies ‐ the Overseas Chinese and the Overseas Indians, collectively referred to as “the Networks”. Measures the sparring rings in Asia through the historical conditions that contributed to the Networks’ fighting stances and to Asian business environments. Proceeds to place the two Asian competitors under the spotlight by highlighting cultural differences between the Networks. Predicts the Networks’ movements by elaborating on their unique management and strategic decision‐making styles and discusses, finally, the implications of the Networks’ business practices for MNCs’ strategies and organizational restructuring in the Asian arena.

Abstract

Purpose

This paper aims to examine the traditional business communities and family businesses of India, their emergence and sustained growth.

Design/methodology/approach

The authors analyze the role of business communities in family businesses of India and identify business communities that have still sustained and marked a global presence.

Findings

Business communities such as Marwaris have the knack for business activities and are leaders of family businesses in India today, who have sustained their past success and continue to create new histories. Other traditional business communities such as Parsis, Sindhis, Chettiars and Gujarati banias have not been able to sustain much. Possible reasons were switching to white-collar jobs, taking up diplomacy and other professions, inter caste marriages, international migration in search of business and Indian government policies.

Research limitations/implications

This study provides a useful source of information for academics, policy-makers and economists.

Practical implications

Traditional business communities populate the list of family businesses that have marked their global presence. This paper identifies various factors that are responsible for the growth and sustainability of these business communities.

Social implications

The study clarifies the role of business communities in domestic economic development.

Originality/value

The paper explored traditional business communities of India and assessed their role in family businesses of India that currently mark a global presence.
