This study has three main purposes: (1) to investigate the association between social media news use and misperceptions about COVID-19; (2) to explore the mediating role of homogeneous online discussion; (3) and to understand whether the extent to which one perceives themselves as media-literate could moderate the relationship.

The authors conducted an online survey and collected data through Amazon Mechanical Turk. A total of 797 participants aged 18 and above completed the survey. The average age of the respondents is 38.40 years (SD = 12.31), and 41.2% were female. In terms of party identification, 30.8% were reported leaning toward Republicans; 53.7% leaned toward Democrats, and 15.4% were reported neutral.

Results from a moderated mediation model show that social media news use is positively associated with misperceptions about the COVID-19. Moreover, homogeneous online discussion was a significant mediator of the relationship between social media news use and misperceptions about COVID-19. Further, self-perceived media literacy (SPML) significantly moderated the main and indirect effects between social media news use and COVID-19 misperceptions, such that the associations became weaker among those with higher SPML.

Findings provide insights into the significance of online information sources, discussion network heterogeneity and media literacy education. Although there have been many studies on misinformation, prior research has not examined these relationships, which may help provide solutions to cope with misinformation.

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

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.

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.

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

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.

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.

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.

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.

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

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.

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).

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.

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.

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

The purpose of this paper is to provide an overview of the wide range of biomimetic sensor technology and innovations.

The reader is introduced to biomimetic sensors, their types, their advantages and how they are different from traditional sensors. Background information is also provided regarding sensor design, inspiration and innovation.

There are two approaches to sensor design, which lead to diverse advantages and innovations. Classification of biomimetic sensors indicated which natural senses are underutilized by sensor designers and researchers.

The paper provides information of value for those seeking innovative sensor designs and research information for those who want to research in this area.

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.

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.

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.

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

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.

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

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”.

This is an original and comprehensive paper by the authors.

Appearance is part of a person's non-verbal communication, and looks are often associated with the perceived ‘attractiveness’ of individuals for hiring practices in the workplace. As such, physical attractiveness can be a ‘prized possession’ when it comes to leaving a positive impression on managers who are interviewing candidates. In the twenty-first century environment, our society seems to be more obsessed with physical appearance than ever before because society has conditioned us to associate beauty with other favourable characteristics. Of course, such appearance norms, regarding attractiveness, ‘good looks’ and beauty are linked to years of socialisation in culture, cultural norms and materialistic personality standards.

In a business context, managers and employers often make hiring decisions based on the appearance and attractiveness of the job applicants since outward appearance seems to play a significant role in which candidates eventually might get the job. Physically attractive job applicants and candidates tend to benefit from the unearned privilege, which often comes at a cost to others who are equally qualified. Preferring employees who are deemed to be attractive, and consequently discriminating against those who are perceived as unattractive, can present legal and ethical challenges for employers and managers. In this chapter, we provide a discussion and reflection of appearance-based hiring practices in the United States with relevant legal, ethical and practical implications for employers, human resources professionals and managers. We focus on ‘lookism’ or appearance discrimination, which is discrimination in favour of people who are physically attractive. As such, we examine federal, state and local laws regarding appearance discrimination in the American workplace. We also offer sustainable policy recommendations for employers, HR professionals and managers on how they can be fair to all candidates in order to hire, promote and retain the most qualified professionals in their departments and organisations.

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.

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.

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.

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

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.

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