Abstract

Purpose

Altmetrics is a complementary method in scientometrics for evaluating the performance of individuals, organizations, institutions and countries in social media. Due to the large volume of data related to the interactions in science, technology and innovation, there is no choice but to develop and implement accurate models for analysis and decision making. The Quadruple Helix Model examines the scientific outcomes in four spaces of innovation, knowledge, consensus and government with a distinctive attention to the “innovation space”. In other words, it aims to find the connection between the academic space and other sectors of a society (public, media and government) to see if scientific outputs respond appropriately to their needs.

Design/methodology/approach

The present paper studied the impact of health-related researches in D8 countries) including Iran, Turkey, Pakistan, Bangladesh, Indonesia, Malaysia, Egypt and Nigeria) using the Altmetrics scores of their indexed journal in the Web of Science (WOS). The results demonstrated distribution of interactions of the mentioned four spaces in health science researches in terms of social media, geographical distribution and theme for D8 countries. This was conducted using content analysis, scientometric and altmetric indicators in the WOS and Altmetrics.com databases.

Findings

In D8 countries, more interaction has taken place in the knowledge and innovation spaces; however, there exist Quadruple imbalances in these countries. Moreover, some interactions have been observed in all social networks, displaying that users consider health topics in D8 countries, and clinical sciences has gotten more interaction in all the four spaces.

Originality/value

The application of this model using altmetrics data with current approach has been conducted for the first time.

Abstract

Purpose

In mature global business-to-business (B2B) product markets, management of external sales channels, governed by contractual relationships, is a key determinant of business performance. However, existing sales channel management literature lacks focus on contractual governance and reseller management success. The purpose of the study is to systematically review different governance theories in relation to sales channel management and to show which factors are the most influential in making or keeping external sales channels effective.

Design/methodology/approach

A case study on a large B2B information and communication technology (ICT) company is used to reflect on the way the different theoretical governance perspectives explain sales channel management success. Interviews and mini-questionnaires were used to collect data.

Findings

Expressions of interdependence and equality alongside persevered personal relationships are important in managing daily business activities and in avoiding bad will at the reseller’s grass-root level. Future-oriented planning, long-term-oriented support and jointly set incentive systems are important for reseller management. Degree of professional management sets resellers apart through shifts in power balance.

Research limitations/implications

A multi-theory governance perspective offers a holistic view over reseller management and provides a comprehensive view over different sales channel management issues and their relative importance.

Practical implications

The findings highlight the importance of long-term orientation and cooperation in setting up a reseller management system to gain and nurture distributors’ trust and commitment towards the manufacturer.

Originality/value

The study is the first to comprehensively use governance perspective in studying reseller management.

Abstract

Purpose

The ratio of the energy liberated during a flight to the revenue work done (ETRW) of an airplane can be employed as a key indicator to assess its environmental impact. It remains constant during the life cycle of the aircraft and is fixed by its designers. The goal of an environmentally optimum airplane is to minimize the ETRW. This paper seeks to address these issues.

Design/methodology/approach

For an existing airplane, there are two major parameters that can greatly affect the ETRW, which are the ratio of actual payload to maximum possible payload “c” and the flight range R. The goal of this paper is to study the effect of c and R on ETRW and minimize it by using a genetic algorithm (GA). The study is performed on a Boeing 737‐800 and a Boeing 747‐400 aircraft as well as recently proposed aircraft designs, namely the Boeing second generation Blended‐Wing‐Body (BWB) and MIT Double‐Bubble D8.2.

Findings

It turns out that the maximum possible values of payload and range do not necessarily lead to a flight with minimal environmental impact. For new aircraft designs, the minimization of ETRW should account for advances in materials, alternative fuels, structures, aerodynamics and propulsion technologies which can be taken into consideration at the design stage.

Research limitations/implications

It should be noted that other factors which also affect the emissions, namely the aircraft operations and air traffic management, are not included in the ETRW.

Originality/value

The optimization study is valuable in determining the payload and range of an existing aircraft or a new aircraft configuration for minimal environmental impact.

Abstract

Online feminist activism has opened a different path for ordinary Iranians who are not necessarily versed in post-revolutionary discourses on feminism and political activism, nor are familiar with the names and past achievements of Iranian women’s activist pioneers since the birth of the Islamic Republic in 1979. Social media has helped to tease apart government statecraft that continually touts and reemphasizes Islamic values, at the same time providing a platform for a feminist consciousness that more recently has passionately supported individual rights, especially the right to privacy. This chapter delves into this move toward a more individualized form of dissent, surveying the generational, ideological, and technological divides that have emerged among Iranian women’s activists following popular uprisings that have been happening domestically since 2009.

Abstract

Purpose

To introduce a research carried out in a real world for implementing a dust control system (DCS) for controlling the indoor air quality (IAP) on the production floor of one of the major electronics company in Malaysia.

Design/methodology/approach

The paper is arranged as follows, a brief description of the significant of DCS in electronic industry and brief introduction to the electronic company as a case study company for introducing the DCS. The discussion on the characteristics management and planning tools (MPTs) that have been adopted as the analysing tools for assisting in the decision‐making process in identifying the problems and improvement strategies. It follows by the detail analysis phase regarding the implementation process that it as backbone for introducing the DCS. Finally a discussion about the result obtained from the MPT analysis on the techniques for identifying the root causes of the dust pollution problem as well as the best improvement strategies that can be adopted by the case study company.

Findings

Three analysis techniques from MPT have been used; there are relation diagram, tree diagram and prioritization matrices analyses. These techniques are very powerful for analysing the specific problem using verbal data. The outputs (results) from these techniques have been used as the solutions to the dust pollution problem. As a result, the implementations of DCS successfully reduce the dust level and stabilise the dust distribution on the production floor.

Practical implications

This paper offer a systematic way in identifying and controlling the IAP in industry.

Originality/value

This paper introduces very useful methods in decision making for identifying the solutions for environmental problem and implementation of DCS in a real world environment.

Abstract

WITH the coming of high speed flight it becomes increasingly necessary to define clearly what is meant by the thrust of a propulsive unit, or if an arbitrary definition is made, a clear idea of the full implications of such a definition is necessary. The latter case is the present day state of affairs, and to cover the inadequacies of our definition of thrust, corrections are necessary under certain conditions. These corrections are usually accepted as an additional burden by the aerodynamicist under the varied titles of ‘spillage drag’, ‘incremental scoop drag’, ‘additive drag’ and ‘pre‐entry drag’ (these terms, while being in the same category, do not in fact all refer to the same thing). These concepts and their relative importance are discussed below.
