Abstract

Purpose

This paper aims to provide an insight into recent biomimetic sensor developments.

Design/methodology/approach

Following a brief introduction, this paper considers a number of specific sensor R&D activities which involve the use of differing biomimetic concepts, including the fabrication of artificial sensing organs, emulating human senses, novel uses of biological structures and systems exploiting biologically‐inspired behaviour.

Findings

This paper shows that a range of different biomimetic design concepts are being applied to sensors that respond to a range of physical, gaseous and chemical variables. Robust, multi‐sensor systems are being developed which emulate biologically‐inspired behaviour.

Originality/value

This paper provides an up to date technical review of a range of differing biomimetic sensor designs and concepts.

Abstract

This paper investigates the effect of three different treatments, namely (i) sunlight exposures, (ii) bleaching and (iii) perming on the damage of the keratin fibres (with the use of human hair). Scanning electron microscopy was applied to examine the surface morphology of the samples. Hair samples appeared to be rougher and their scales diminished after the treatments. The degree of colour change of samples was measured using a diffuse reflectance spectrophotometer. All three different treatments caused a certain degree of colour change on the samples. Urea bisulphite solubility test was also employed to investigate the alkaline damage of samples.

The results illustrated that the urea bisulphite solubility of samples conformably decreased when they were subject to these three types of treatments. With respect to the tensile strength property, the results indicate that the breaking load of treated samples decreased dramatically after undergoing three different types of treatments. On evaluating the test results, it was concluded that the bleaching process imparted the most severe damages to hair. The results of the different test methods were evaluated and discussed.

Abstract

Purpose

This paper aims to present a state-of-the-art review in various fields of interest, leading to a new concept of bio-inspired control of small aircraft. The main goal is to improve controllability and safety in flying at low speeds.

Design/methodology/approach

The review part of the paper gives an overview of artificial and natural flow sensors and haptic feedback actuators and applications. This background leads to a discussion part where the topics are synthesized and the trend in control of small aircraft is estimated.

Findings

The gap in recent aircraft control is identified in the pilot–aircraft interaction. A pilot’s sensory load is discussed and several recommendations for improved control system architecture are laid out in the paper.

Practical implications

The paper points out an opportunity for a following research of suggested bio-inspired aircraft control. The control is based on the artificial feeling of aerodynamic forces acting on a wing by means of haptic feedback.

Originality/value

The paper merges two research fields – aircraft control and human–machine interaction. This combination reveals new possibilities of aircraft control.

Abstract

Purpose

The purpose of this paper is to design and fabricate a three-dimensional (3D) bionic airflow sensing array made of two multi-electrode piezoelectric metal-core fibers (MPMFs), inspired by the structure of a cricket’s highly sensitive airflow receptor (consisting of two cerci).

Design/methodology/approach

A metal core was positioned at the center of an MPMF and surrounded by a hollow piezoceramic cylinder. Four thin metal films were spray-coated symmetrically on the surface of the fiber that could be used as two pairs of sensor electrodes.

Findings

In 3D space, four output signals of the two MPMFs arrays can form three “8”-shaped spheres. Similarly, the sensing signals for the same airflow are located on a spherical surface.

Originality/value

Two MPMF arrays are sufficient to detect the speed and direction of airflow in all three dimensions.

Abstract

This case features an entrepreneur striving to rapidly grow a successful chain of hair salons that serve women with afro hair. After doubling from 13 to 26 salons across Brazil in 2014, the founders' expansion plan called for 120 Beleza Natural salons and R$1 billion in sales by 2018. CEO and cofounder Leila Velez is considering various fundamental marketing strategies to catalyze growth: Should Beleza launch a new mass-media campaign, increase promotional discounts, expand its target market to serve men, broaden its service offerings, streamline processes to reduce wait times, expand distribution channels, or franchise? Students assume the role of Velez and are asked to recommend which growth strategy would be their top priority. In doing so, they are required to evaluate how these strategies pertain to the company's business model and value proposition. They are also challenged to consider what a brand is and what makes a strong service brand in order to verify if their strategies are consistent with Beleza's brand. The teaching note outlines a framework for developing or evaluating a business model as well as developing strategies for managing growth. The case is accompanied by a series of video interviews with Velez that support case preparation, in-class discussion, and key learning points.

Abstract

Purpose

The article aims to provide a discussion of societal norms concerning “attractiveness,” the existence of appearance discrimination in employment, the presence of “preferring the pretty”, and then the authors examine important civil rights laws that relate to such forms of discrimination. Finally, the authors apply ethical theories to determine whether such discrimination can be seen as moral or immoral.

Design/methodology/approach

It is a legal paper which covers all the laws related to discrimination based on look. Court cases and Americans laws related to this concept are reviewed and critically discussed.

Findings

The paper finds that appearance‐based discrimination is not illegal in the USA so long as it does not violate civil rights laws.

Research limitations/implications

This research is limited to Federal and State laws in the USA and may not be relevant in other countries as the local laws might vary.

Practical implications

Managers and employees can protect themselves in the workplace from illegal discriminatory practices.

Social implications

Employees know their rights and enhance their understanding of laws related to appearance, attractiveness, and why companies look to hire those who are considered “handsome”, “pretty” and “beautiful”.

Originality/value

This is an original and comprehensive paper by the authors.

Abstract

Purpose

The aim of this paper is to analyse the role of creative re-appropriation of goods, symbols, and other manifestations of the dominant material culture in the Emo subculture identity construction process.

Design/methodology/approach

The authors conducted an ethnographic study on a purposive sample of social networks, blogs, discussion forums and online platforms for images sharing. Verbatim and visual texts as photos, drawings and moodboards were qualitatively content analysed in order to understand the network of meanings underlying the ambiguous amalgam of signs composing the Emo style.

Findings

Consistent with the literature, the qualitative content analysis of texts, images, videos, drawings and other forms of fan art typical of this micro culture revealed four key areas of semantic value: the aestheticization of inner pain, the sense of alienation and isolation from socio-cultural mainstream, the search for authenticity, and the need for emotional connection.

Research limitations/implications

The research followed a quite new research method, the netnographic approach, originally developed to analyse brand communities.

Practical implications

Emo creative practices of re-appropriation of goods, symbols and icons of the dominant culture reveal a subtle message of protest against the consumer society and the commodification of everyday life.

Originality/value

The paper presents the deconstruction of Emo Lifestyle and Aesthetics analysing the system of meanings underneath the rituals Emos share through the Web.

Abstract

Purpose

While the current anti-globalisation wave is considered as a regional and cyclical relapse among Western countries, the new era of globalisation has shifted away from stagnant developed economies towards the rising prosperity of emerging Asia, where it is attracting substantial global inward foreign direct investment (FDI). Focussing on Vietnam, the country that is seen as Asia’s next economic tiger, the question of how important intellectual properties (IP) protection is in the international competition for FDI inflows is still unsettled, especially on the under-researched topic of trademarks.

Design/methodology/approach

This paper takes on the business history approach, which allows rich evidence from the dynamic and evolving natures of multinational enterprises (MNEs) to drive the research process, so that international business scholars can test models rigorously. The evidence provided in this paper is essentially qualitative and combines trademark registrations data, with trade and FDI statistics between 1986 and 2016, also draws on companies’ archives, industry reports and related newspaper articles.

Findings

This paper provides the chronology of intellectual property right (IPR) legal landscapes and the dynamic co-evolution of trademarks and FDI inflows in Vietnam. Three trademark protection strategies for MNEs and their patterns here are addressed. The paper also argues that trademarks bring new insights and IP protection strategy for pharmaceutical MNEs for the case of Vietnam is as important in trademarks as it is in patents. In emerging markets with strong incentives for FDI such as Vietnam, MNEs are not necessarily put off by weak IPR, but rather create alternative strategies for dealing with the lack of IP protection in these emerging market settings.

Originality/value

This study challenges the stream of thoughts that view trademarks as a “neglected intangible asset” among different IPRs, while in fact, trademarks advance MNEs’ knowledge by ensuring competitiveness and long-run survival in emerging markets. This paper is among the first few attempts to look at pharmaceutical industry through the lens of trademarks, moving away from the traditional patent-focussed approach. It extends the understanding of OLI paradigm and highlights that MNEs need to possess Oa and Op advantages not only at the beginning of internationalisation process but rather evolving through the time to cope with imitation risks in the host country.

Abstract

Purpose

The purpose of this paper is to study the innovative design of prosthetic hands now in production from a Scottish spin‐off company.

Design/methodology/approach

The novel features are described, followed by the details of the mechanical construction and the available grip patterns. The benefits of the modular design are explained, and the function and construction of a skin‐like covering are explored. The clinical network supporting the prosthesis is briefly outlined.

Findings

The design allows patients to achieve many functional and natural‐looking hand configurations from simple “open” and “close” signals. Miniature motors and gearboxes allow independent movement of each digit, and an integral microprocessor translates electric signals from the forearm to control the movements of the hand. Stall detection ensures that no finger exerts excessive force or wastes power. Artificial skin can be very realistic, with imitation fingernails, hairs and pores. The lifelike prosthesis helps the patient emotionally, socially and at work.

Originality/value

The paper shows how advances in motors, gearboxes, batteries and electronics have enabled a breakthrough in prosthetic design.
