In this chapter, the authors present a theoretical framework to not only better understand the wicked nature of the Airbnb phenomenon but also, using case examples from around the world, to illustrate how governments have attempted to mitigate Airbnb’s negative impacts.

Analysing the sharing economy, specifically the Airbnb platform, through the lens of Karl Polanyi’s Double Movement Theory, brings growing tension between markets and society into sharp relief. In the ensuing sections of this chapter, the authors will then adopt a ‘wicked problem’ perspective to provide some analytical insights into how governments across the world have attempted to respond to this wicked policy problem and explore different policy responses and regulatory frameworks in greater depth. Through the review of exemplary cases from around the world, considerable variation in governance and policy responses could be identified.

The Purpose of this study is to prove the possibility of developing low cost mechanical anti – lock braking system (ABS) for the passenger’s safety.

The design methodology of the proposed newer mechanical ABS comprises of two units, namely, the braking unit and wheel lock prevention unit. The braking unit actuates the wheel stopping as and when the driver applies the brake, whereas the wheel lock prevention unit initiates wheel release to prevent locking and subsequent slip/skidding. The brake pedal with master cylinder assembly and double-arm cylinder forms the braking unit, brake pad cylinder, movable brake pad, solenoid valve and dynamo forms the wheel lock prevention unit. The dynamo coupled with the rotor energises/de-energises the solenoid values to direct airflow for applying brake and release it, which makes the system less energy-dependent.

The braking unit aids in vehicle stops, by locking the disc with the brake pad actuated by a double-arm cylinder. The dynamo energises the solenoid valve to activate the brake pad cylinder piston for applying the brake on the disc. Instantaneously, on applying the brake the dynamo de-energises the solenoid to divert the pneumatic flow for retracting the brake pad thereby minimizing the braking torque. The baking torque reduction revives the wheel rotating and prevents slip/skidding.

Mechanical ABS preventing wheel lock by torque reduction principle is a novel method that has not been evolved so far. The system was designed with repair/replacement of the parts and subcomponents to support higher affordability on safety grounds.

The present numerical investigation examines the magnetohydrodynamic (MHD) double diffusion natural convection of power-law non-Newtonian nano-encapsulated phase change materials (NEPCMs) in a trapezoidal cavity.

The governing Navier-Stokes, energy and concentration equations based on the Cartesian curvilinear coordinates are solved using the collocated grid arrangement’s finite volume method. The in-house FORTRAN code is validated with the different benchmark problems. The NEPCM nanoparticles consist of a core-shell structure with Phase Change Material (PCM) at the core. The enclosure, shaped as a trapezoidal hollow, features a warmed (T_h) left wall and a cold (T_c) right wall. Various parameters are considered, including the power law index (0.6 ≤ n ≤ 1.4), Hartmann number (0 ≤ Ha ≤ 30), Rayleigh number (10⁴ ≤ Ra ≤ 10⁵) and fixed variables such as buoyancy ratio (Br = 0.8), Prandtl number (Pr = 6.2), Lewis number (Le = 5), fusion temperature (Θ_f = 0.5) and volume fraction (ϕ = 0.04).

The findings indicate a decrease in local Nusselt (Nu) and Sherwood (Sh) numbers with increasing Hartmann numbers (Ha). Additionally, for a shear-thinning fluid (n = 0.6) results in the maximum local Nu and Sh values. As the Rayleigh number (Ra) increases from 10⁴ to 10⁵, the structured vortex in the streamline pattern is disturbed. Furthermore, for different Ra values, an increase in n from 0.6 to 1.4 leads to a 67.43% to 76.88% decrease in average Nu and a 70% to 77% decrease in average Sh.

This research is for two-dimensioal laminar flow only.

PCMs represent a class of practical substances that behave as a function of temperature and have the innate ability to absorb, release and store heated energy in the form of hidden fusion enthalpy, or heat. They are valuable in these systems as they can store significant energy at a relatively constant temperature through their latent heat phase change.

As per the literature review and the authors’ understanding, an examination has never been conducted on MHD double diffusion natural convection of power-law non-Newtonian NEPCMs within a trapezoidal enclosure. The current work is innovative since it combines NEPCMs with the effect of magnetic field Double diffusion Natural Convection of power-law non-Newtonian NEPCMs in a Trapezoidal enclosure. This outcome can be used to improve thermal management in energy storage systems, increasing safety and effectiveness.

The Albanian migration has always reflected a family character, be that before 1945 when Albania was not yet completely isolated, as well as after 1990 when borders were reopened. This feature characterized all types of movement, internal or international, permanent or seasonal migration, return migration or transnational movements and remigration. The purpose of this study is to investigate the role of the family as a very important factor in making decisions regarding migration and answering questions from why to how to migrate, from when to where, whom to ask for help or how to invest remittances.

Based on the case study of a rural area in Northern Albania, the Administrative Unit of Dajç, this paper explores in detail the roles of family and kinship on decisions regarding return migration, the re-adjustment process, remigration or transnational life.

By exploring the role of the family context in remigration and vice-versa, the paper reflects that the family biography – including the lifestyle, plans for the future or expectations – has changed due to previous migration experiences or challenges and difficulties when returning to the home country.

It demonstrates how individual decisions to migrate or to “return home” are negotiated and supported within families making transnational life a family project. The paper adopts a new approach in the Albanian Migration Studies, which may be implied on broader areas for further research in the future.

Research indicates a long historical connection between racism and nationalist ideologies. This connection has been highlighted in the resurgence of exclusionary nationalism in recent years, across many multicultural societies. This chapter discusses the notions of race, ethnicity and nation, and critically examines how racism shapes contemporary manifestations of nationalist discourse across the world. It explores the historical role of settler-colonialism, imperial expansions and the capitalist development in shaping the racial/ethnic aspect of nationalist development. Moreover, it provides an analysis of the interconnections between the racialisation of minorities, exclusionary ideologies and the consolidation of ethno-nationalist tropes. This chapter further considers the impact of demographic changes in reinforcing anti-migrant exclusionary sentiments. This is examined in connection with emerging nativist discourse, exploring how xenophobic racism has shaped and is shaped by nostalgic nationalism based on the sanitisation of the legacies of Empire and colonialism.

This section begins with the story of Raul, a young homeless man who dwells in the streets of Buenos Aires city. Raul is 25 years old and has four children who live with his former wife. Divorced because of a problem with drinking, he sleeps here, there, and everywhere but prefers bus stations or tourist destinations. In this way, he not only feels safer but also lives on the charity of foreign tourists. Hotels or bus stations offer safe shelter in case of rain or the ruthless winter. Because of the currency exchange gap between pesos and dollars, tourist destinations are targeted by many homeless men in Buenos Aires City. Having said this, he works as “reciclador urbano – urban recycling” a new nomenclature associated with persons who sort trash to collect recyclables. Known as cartoneros (litter-pickers) as well, these persons started to become a part of Buenos Aires city. At first glimpse, many cartoneros never come back to their homes, located in Provincia de Buenos Aires they sleep and live roaming Buenos Aires traversing from one to another point of the city. The opposite is equally true, like Raul, Buenos Aires airport has turned into an unofficial homeless shelter receiving more than 50 persons each night.

This paper aims to investigate how and when visual referents in brand visual aesthetics (i.e. colours, shapes, patterns and materials) serve as design applications that enable consumer diasporic identity.

This paper uses an innovative methodology that triangulates 58 in-depth interviews with diasporic consumers, 9 interviews with brand managers and designers and a visual analysis of brands (food retailer, spices and nuts, skincare, hair and cosmetics, ice cream and wine) to provide a view of the phenomenon from multiple perspectives.

This study illustrates how and when particular applications and compositions of product and design referents support diasporic identity for Middle Eastern consumers living outside the Middle East. Specifically, it illustrates how the design applications of harmonising (applying separate ancestral homeland and culture of living product and design referents simultaneously), homaging (departing from the culture of living product and design referents with a subtle tribute to ancestral homeland culture) and heritaging (departing from the ancestral homeland culture product and design referents with slight updates to a culture of living style) can enable diasporic identity in particular social situations.

Although applied to the Middle Eastern diaspora, this research opens up interesting avenues for future research that assesses diasporic consumers’ responses to brands seeking to use visual design to engage with this market. Moreover, future research should explore these design applications in relation to issues of cultural appreciation and appropriation.

The hybrid design compositions identified in this study can provide brand managers with practical tools for navigating the design process when targeting a diasporic segment. The design applications and their consequences are discussed while visually demonstrating how they can be crafted.

While previous research mainly focused on how consumption from the ancestral homeland occurred, to the best of the authors’ knowledge, this study is the first to examine how hybrid design compositions that combine a diaspora’s ancestral homeland culture and their culture of living simultaneously and to varying degrees resonate with diasporic consumers.

It is widely agreed that transformation processes that are triggered by crisis events can challenge conventional behavioural norms and stimulate new ideas and innovations that can assist in the preparations for future challenges. This impetus for transformation processes not only applies to the COVID-19 pandemic, but has also been seen in many other instances, such as the Global Financial Crisis in 2008 or the 2011 Fukushima nuclear disaster, which have sparked significant socio-political change processes often with a global reach. The multitude of wicked tourism policy problems discussed in our book often occur in parallel, are of growing complexities, are often not well understood and indistinguishable from one another and exert pressure on the resilience of vulnerable political, economic and community-based systems. These circumstances often present as tipping points which can trigger necessary long-term transformations. However, this process of long-term change must be well planned and strategically implemented. Thus, future transformative destination management should be built on a holistic approach, underpinned by adaptive political leadership in which tourism is not only seen as a driver for economic growth and employment, but as a strategy which successfully integrates social, cultural and ecological goals.
