Abstract
Research methodology
For the design of this case study, the authors used primary sources of information from the shops visited by them in preparation of the case and website of Fred Perry and secondary sources of information from both academic and journalistic publications.
Case overview/synopsis
Fred Perry is a premium clothing brand, well-known for its polo shirts. It was created by Mr Fred Perry, a British tennis player. The brand’s stated values are integrity, personality and individuality. Throughout its history, the brand has been adopted by different British subcultures but recently it has faced a challenge because of the brand appropriation by the Proud Boys, a US far-right white supremacy group and other extremist groups as Antifa and hooligans. The nature and actions of the group mean that Fred Perry runs the risk of losing control over its brand equity. This brand hijack means that Fred Perry risks alienating some of its customers by openly opposing the group but also by embracing this subculture’s appropriation. Practically, the brand opposed the appropriation in a press release and by putting an end to the sale of the black and yellow polo shirts in the USA and Canada. Fred Perry has also made a lot of efforts to reposition the brand away from extremist groups while maintaining its strong historical and cultural roots. Through this case study, students will have the opportunity to discuss this topic and explore solutions for brands that face this type of dilemma.
Complexity academic level
This case is designed to be used in a marketing management, brand strategy or consumer behavior/culture course, especially in the subfield of market segmentation in the telecommunications sector. Specifically, this case is designed for college seniors or master students with basic strategic marketing training. This case will help students understand the difference between the brand identity that the brand owners intend and the brand image that consumers actually perceive. It provides the basis of discussions on the topics of brand management, consumer culture, consumers-brands relationships, brand architecture, brand equity, brand appropriation and repositioning strategy.

Abstract
Purpose
The paper discusses how the management of a sports and fashion company, which we refer to as NULMA, successfully applied the neo/normative control technology “karma organisation” and gained employee engagement. Whereas other studies have documented employee resistance to organisational cultures when used for managerial control, our case demonstrates resistance to management practices that employees find inconsistent with the dominant karma culture.
Design/methodology/approach
The study is based on a six-year longitudinal organisational at-home ethnography conducted by one of the authors using methods of both participant and non-participant observation, semi-structured interviews and collaborative production of secondary data in the case organisation.
Findings
While our research shows that management can successfully apply neo/normative control which employees accept and support, we further show that employees mobilise the same values to resist management when it fails to deliver on the commitments and promises of the organisational culture.
Originality/value
The study contributes to the literature on organisational culture and, in particular, neo/normative control by theorising employee resistance as being by “accident”, by which we mean an inherent negative potentiality co-invented and released by managers establishing a “karma organisation”. Our theorising culminates in a discussion of the study’s implications for research and practice.

Abstract
Purpose
This study aims to investigate the morphing concepts able to manipulate the dynamics of the downstream unsteadiness in the separated shear layers and, in the wake, be able to modify the upstream shock–boundary layer interaction (SBLI) around an A320 morphing prototype to control these instabilities, with emphasis to the attenuation or even suppression of the transonic buffet. The modification of the aerodynamic performances according to a large parametric study carried out at Reynolds number of 4.5 × 106, Mach number of 0.78 and various angles of attack in the range of (0, 2.4)° according to two morphing concepts (travelling waves and trailing edge vibration) are discussed, and the final benefits in aerodynamic performance increase are evaluated.
Design/methodology/approach
This article examines through high fidelity (Hi-Fi) numerical simulation the effects of the trailing edge (TE) actuation and of travelling waves along a specific area of the suction side starting from practically the most downstream position of the shock wave motion according to the buffet and extending up to nearly the TE. The present paper studies through spectral analysis the coherent structures development in the near wake and the comparison of the aerodynamic forces to the non-actuated case. Thus, the physical mechanisms of the morphing leading to the increase of the lift-to-drag ratio and the drag and noise sources reduction are identified.
Findings
This study investigates the influence of shear-layer and near-wake vortices on the SBLI around an A320 aerofoil and attenuation of the related instabilities thanks to novel morphing: travelling waves generated along the suction side and trailing-edge vibration. A drag reduction of 14% and a lift-to-drag increase in the order of 8% are obtained. The morphing has shown a lift increase in the range of (1.8, 2.5)% for angle of attack of 1.8° and 2.4°, where a significant lift increase of 7.7% is obtained for the angle of incidence of 0° with a drag reduction of 3.66% yielding an aerodynamic efficiency of 11.8%.
Originality/value
This paper presents results of morphing A320 aerofoil, with a chord of 70cm and subjected to two actuation kinds, original in the state of the art at M = 0.78 and Re = 4.5 million. These Hi-Fi simulations are rather rare; a majority of existing ones concern smaller dimensions. This study showed for the first time a modified buffet mode, displaying periodic high-lift “plateaus” interspersed by shorter lift-decrease intervals. Through trailing-edge vibration, this pattern is modified towards a sinusoidal-like buffet, with a considerable amplitude decrease. Lock-in of buffet frequency to the actuation is obtained, leading to this amplitude reduction and a drastic aerodynamic performance increase.

Abstract
Purpose
The qualitative approach was applied the discover the optimum answers to the research objectives, which are (1) to understand the cultural and hedonistic characteristics of the (Lanna) Songkran festival; and (2) to examine the dilemma between cultural rituals and hedonistic activity for tourism.
Design/methodology/approach
This study used a case study of the Songkran festival in Chiang Mai to examine the dilemma between cultural rituals and hedonism for tourism, which brings lost or misperceived cultural values and identities. The semi-structured interview (SSI) with senior locals and participant observation during the festival was conducted in Chiang Mai, Thailand, to obtain the in-depth phenomena of the existing celebration pattern at the festival.
Findings
The study findings show three crucial phenomena that explain characteristics of unsynchronized cultural rituals and hedonistic activities for tourism: (1) the parallel phenomenon between cultural values and celebration practice, (2) the movement of local culture and(3) the hedonistic characteristics of the festival.
Practical implications
The study extends the knowledge on the interplay phenomena between cultural festivals and tourism; also, the involved stakeholders, such as local communities, public sectors and private sectors, can use the study findings in creating policies for using cultural festivals to promote a destination and urban economic development that will minimise cultural values distort while increase tourism economic values.
Originality/value
This study was conducted qualitatively, including SSIs and participant observation at the Songkran festival in Chiang Mai. The study findings were analysed, based on the empirical data, into significant themes representing the characteristics of dilemma phenomena within the festival.

Abstract
Purpose
Breast cancer is the most diagnosed type of cancer in the world, and mastectomies to remove tumors are still common. An external breast prosthesis (EBP) can be used to minimize the asymmetry, due to the ablation. Some governments do not cover costs of that assistive technology, and women end up using socks and fabric pockets filled with seeds, to simulate the volume lost in the surgery. This study aims to offer to those women a decent solution, ergonomic, but still affordable.
Design/methodology/approach
The authors interviewed 20 mastectomized Brazilian women, listened to their relate and 3D scanned them, to give rise to personalized external lightweight breast prostheses. The authors used free software for computer-aided design and computer-aided manufacturing, and low-cost 3D printers. From the strategy of bespoke products, this study generalized the method, to conceive mass customized prostheses, in a compromise solution that reduces personalization, conserving the best features of design.
Findings
This study achieved a method to manufacture ergonomic, bespoke external breast prostheses, using low-cost technology. Previous literature made them using expensive scanners, software and printers.
Research limitations/implications
The authors validated this method during pandemic, which restricted the number of patients the authors could have access to. This impacted authors’ possibility to work on matching the color of the final product and real skin. The authors understood, though, that precision of color, in the final product, is challenging, because of the peculiar aspects of human skin.
Originality/value
Using the method the authors proposed, personalized external breast prostheses can be manufactured using low-cost resources, democratizing better quality of life for more breast cancer survivors.

Known for its motto “All Ages, All Races, All Genders,” MAC cosmetics reflects the brand’s commitment to inclusivity and diversity. It has been at the forefront of promoting a wide range of skin tones, ethnicities and gender identities in the beauty industry. If you have ever wondered about the secret behind the success of this mega-brand in the beauty industry, this case study aims to provide a comprehensive overview of the company’s history from its early days to the present and discusses the factors that might build or ruin a brand. Moreover, players in the industry will need to adapt to changing consumer preferences, focus on sustainability and leverage digital technologies to remain relevant and capture market opportunities. Therefore, would it be wise for MAC cosmetics to take forward their expansion plans in India, and what is the motivation behind the expansion? Alternatively, would the implementation of a proactive strategy for product innovation, combined with a stronger presence, result in a more viable and sustainable proposition?
Design/methodology/approach
This study relies on online resources for data collection. The data was collected from the secondary sources in the month of November and December 2022. Moreover, the information provided in the case study was validated and supplemented via using different websites, including the company’s website and social media profiles.
Findings
The commitment shown and the roles played will have a lasting impact on the society. Additionally, student will be able to learn when and how to seize opportunities, as well as how to manage obstacles that will arise in their entrepreneurial journey. Through this case study, they will be able to learn a variety of business strategies that can be implemented in emerging markets. The conclusion of the study provides the obstacles and hurdles faced by the industry in expanding in the Indian market. The potential solutions were made through providing information for the students, academicians, entrepreneurs and others to compete in the Indian market situation.
Originality/value
This is a real-world case that provides the audience with first-hand experience to comprehend the event and apply their knowledge to form a conclusion and is also effective for decision-making in the dynamic environment of the present day. However, the authors provide a comprehensive overview of the company’s history from its early days to the present and discuss the factors that might build or ruin a brand.

Abstract
Purpose
This study aims to add to the understanding of the significance of football in cities, where most major football clubs are located. Specifically, this study offers a distinctive perspective on what might be regarded as “football cities” by the study's mobilisation of theories of the urban mosaic, the calculable city and identity. This study contributes to the emergent field of popular culture (Jeacle, 2012) and, within this field of popular culture, the significance of soccer. The particular setting of this study is the city. This paper is a contribution to the established accounting literature on city studies but within the neglected study of football in cities.
Design/methodology/approach
This paper's focus is on the significance of football clubs in one city. The theoretical approach adopted is a blending of studies of the urban mosaic (Timms, 1975), the calculable city (Lapsley et al., 2010) and the established trend of identification studies in accounting. This investigation was undertaken in the city of Edinburgh by observation of football in city life. This research is a form of participant observation in which the author lived in the city in this study. The researcher undertook interviews with key actors in both football clubs and city management, made use of local media and scrutinised publicly available documents on both the clubs and the city administrations.
Findings
This research reveals the importance of the city mosaic in explaining the limited significance of football in this city. This approach underlines the merits of contextual studies. However, the evidence presented also reveals the presence of strong identity relationships between football clubs and the clubs' fans. These results reveal an internal perspective on city management and the activities of football clubs and the clubs' host city. The presence of multiple football clubs in a single city offers more diffuse identity relationships, with football clubs fostering stronger identification with the club than with the city. There is also evidence of single, dual and multiple identity relationships in this study which contrasts with the single identity perspectives of prior accounting research.
Research limitations/implications
The focus of this paper is on the research question posed in the Call for Papers - Is there a Soccer Society? The findings of this study offer only limited evidence of a soccer society.
Practical implications
There is a need to study other cities with football clubs to determine those which are mosaics and those which are dominated by football.
Social implications
This a study which embraces the importance of social context in finding meaning in accounting research. This paper introduces the novel concept of the city mosaic which is a novel way of understanding different city contexts.
Originality/value
Prior research on football has examined fans' behaviour, financial crises at football clubs and governance structures. This paper extends these earlier analyses by addressing the social context of football clubs in the city. Whilst most accounting research revealed rapid changes in identity during reforms, this study reveals a more complex relationship which aims to build continuity and commitment of fans' identity with the bigger football clubs in this city.
