In search of opportunities for development of microinsurance by drawing on the experience of previous generations
Authors: Sułkowska Wanda
Published: January 2022

Motivation: Notwithstanding the 30 years of the market economy, the Polish insurance market still reveals an exceptionally low level of penetration rates and insurance density. Attempts should be made to reduce the protection gap by introducing and popularising microinsurance products.

Aim: The research aims to establish whether there exists a need for microinsurance products in Poland and whether there are conditions for its development, which groups it should target and what methods and institutions can reduce the protection gap.

Results: Data analysis demonstrated that in Poland the lowest use of insurance coverage to manage risk occurs in the lowest income households, comprising groups of people with relatively low education: disability pensioners, farmers and workers. This results in lack of or limited access to insurance. Looking for a way to counteract this phenomenon, I suggest introducing and popularising microinsurance products targeting towards the above-mentioned groups. However, the use of remote microinsurance distribution channels may prove highly ineffective. Considering the above and the lack of trust in entities operating in the insurance market, it is recommended to create a legal environment enabling the inclusion of institutions and organisations acceptable to and enjoying the trust of these circles in processes involving marketing, distribution and, partially, the servicing of microinsurance. These players should consist of civic organisations, such as volunteer fire brigades, rural housewives’ clubs, activist organisations from religious communities, as well as those set up for mutual protection, e.g., relief and loan funds and savings and loan funds. A separate group targeted by microinsurance should consist of people who are young, open to new trends and interested in obtaining insurance coverage for a limited time, e.g., for the short period when they use a means of personal transport or other rented equipment, for which coverage can be obtained and paid for quickly and without undue formalities.
Polish National Cittaslow Network: assessment of cities’ membership in the network
Authors: Wierzbicka Wioletta
Published: January 2022

Motivation: The Polish National Cittaslow Network associates 31 members and is the second most biggest national network of slow cities in the world. The network is developing very dynamically. Therefore, it is important to observe this relatively new and not fully recognized process of implementing the slow city model in Polish cities, and to assess the effects of cities’ membership in this network.

Aim: The aim of the study was to evaluate effects of the membership of cities in the Polish National Cittaslow Network. The effects were assessed on the basis of a comparative analysis of the results of certification carried out before a city accessed the network with the results of recertification, carried out 5 years into its membership. A diagnostic survey method was also used in the study.

Results: The research shows that already in the first five years of the membership in the network, the cities have undertaken many activities to enhance their appeal as a tourist destination, promote local products and protect the historic and cultural heritage. The cities have completed many revitalisation projects. New tourist trails, bicycle paths and recreational areas have been created. Undoubted, the membership in the Cittaslow network has generated many benefits to the cities. This is reflected by the higher degree of the fulfilment of the certification criteria by all cities. This is also confirmed by the results of a diagnostic survey conducted among the mayors of member cities.

How Is Mobile User Behavior Different? A Hidden Markov Model of Cross-Mobile Application Usage Dynamics
Authors: Wu Shaohui , Tan Yong , Chen Yubo , Liang Yitian (Sky)
Published: January 2022

Driven by the ubiquity and strong context dependence of mobile app use, Internet companies are in a race of cross-industry expansion to build a seamless ecosystem incorporating various contexts. This paper offers several insights on improving app use in the era of mobile Internet. In contrast to PC Internet, in addition to hedonic and utilitarian states, we uncover a novel social state that is prevalent but transient, indicating mobile users have a fundamental need for frequent light-social activities. Thus, one strategy to increase use is to enrich an app’s social components, specifically on light-social functionalities. In addition, our results show that app use interdependence is the strongest under the hedonic state. This indicates the strategic value of boosting current app use is the highest in the hedonic state, providing guidance to companies on better spending of their limited marketing resources. Furthermore, we show that these internal states are interdependent of each other and their dynamic is affected by contextual factors that are distinct in the mobile context. Thus, companies should put more weight on tailoring their engagement strategies under different contexts in the ear of mobile Internet than the traditional PC context.

A New Family of Valid-Inequalities for Dantzig-Wolfe Reformulation of Mixed Integer Linear Programs

In “Consistency Cuts for Dantzig-Wolfe Reformulation,” Jens Vinther Clausen, Richard Lusby, and Stefan Ropke present a new family of valid inequalities to be applied to Dantzig-Wolfe reformulations with binary linking variables. They show that, for Dantzig-Wolfe reformulations of mixed integer linear programs that satisfy certain properties, it is enough to solve the linear programming relaxation of the Dantzig-Wolfe reformulation with all consistency cuts to obtain integer solutions. An example of this is the temporal knapsack problem; the effectiveness of the cuts is tested on a set of 200 instances of this problem, and the results are state-of-the-art solution times. For problems that do not satisfy these conditions, the cuts can still be used in a branch-and-cut-and-price framework. In order to show this, the cuts are applied to a set of generic mixed linear integer programs from the online library MIPLIB. These tests show the applicability of the cuts in general.

Authors: Booth Michaela , Harriott Paula
Published: January 2022

This chapter highlights the pains of women's imprisonment, looking at the contemporaneous and longitudinal impact on their health and wellbeing, their family life, their mothering identity, stigma, and relationships. It explores the lived experience of two women who went to prison and were researched, covering researcher–participant relationships, power, purpose, ownership, and ethics. It also delves into concerns that women's collective and personal experiences of pain are subjected to being used, manipulated, and repackaged. The chapter talks about the marginal benefit and minimal impact of experiences on the actual lives of the criminalised women. It analyzes the truthful and in-depth recollection of involvement in research as criminalised women subjects.
South Asian and BME migrant women’s experiences of culturally tailored, women-only physical activity programme for improving participation, social isolation and wellbeing
Authors: Darko Natalie
Published: January 2022

The chapter discusses the delivery and evaluation of a women-only physical activity and yoga programme designed to improve physical activity, social isolation and well-being amongst South Asian and Black and Minority Ethnic (BME) migrant women living in areas of high economic deprivation. The chapter provides an accessible insight into the aims, objectives, methods and findings of the study. It provides important recommendations on how researchers and service providers can deliver culturally tailored community-based health interventions It will be demonstrated that social support such as childcare provision, child-friendly sessions and social media forums, determined by the target population can mitigate misconceptions about South-Asian and BME migrant women as being difficult to engage in health interventions.
Experiences of health and wellbeing during periods of fragile and uncertain citizenship among African-Caribbean migrant groups
Authors: Darko Natalie
Published: January 2022

The UK African- Caribbean population includes migrants originating from various Caribbean islands. However, many have experienced differentiated experiences in health and well-being since their migration. They have and continue to be impacted by experiences of racism, marginalisation, and uncertain residency status that has impacted on their health and wellbeing and that of their family members.
This chapter explores the impact of migration on the health and well-being of African- Caribbean people who moved to the UK at any time from the 1940s to the present day, or whose immediate family did so. It outlines how participants of African-Caribbean heritage have experienced their health and healthcare access since their arrival to the UK and during periods of fragile and/or uncertain citizenship. Life storytelling methods are utilised to produce bibliographic accounts of the participants lives. Methods for developing and building sustained partnerships between migrants and researchers are also discussed. Specifically, the chapter draws attention to the ways in which future research can be delivered in collaboration with BME migrants to understand their migration journeys.
Between Publics and Platforms
Authors: Carrigan Mark , Fatsis Lambros
Published: January 2022

This chapter analyzes the negotiation between the desire to be public and the limits and possibilities of social media, exploring the relationship between publics and platforms that plays out on a very unstable ground. It highlights the constraints that the architecture of online platforms imposes on its users' ability to exploit them for one's purposes. It also addresses the question of how or whether social media users can exercise agency independently of the restrictive design of such platforms. The chapter discusses the desire to vie for the eyes and ears of followers online, losing sight of how much time is spent feeding an attention economy that can easily turn utopian expectations about networked activism into dystopian fears of subjugation and submission to surveillance capitalism. It features utopian ambitions that defined the internet as it grew and revolved heavily around virtuality, noting the possibility of escape from the mundane constraints of the physical world and the promise of a better world.
Sociology and its Platforms
Authors: Carrigan Mark , Fatsis Lambros
Published: January 2022

This chapter disconnects from the online world to explore the relationship between sociology and its platforms. It approaches platforms as positions from which to communicate that are facilitated by technological infrastructures in digital or analogue. It also rethinks the relationship between sociology and its platforms to remind that sociology did not wait for the arrival of the internet to communicate its insights, but has always relied on other, earlier media technologies to do so. The chapter mentions print and broadcast media that predate the emergence of digital technology. It contextualizes the radical transformations that social media brought about as they became an institutionalized feature of academic life as dissemination engines and tools for generating publicity.
Making Sociology Public
Authors: Carrigan Mark , Fatsis Lambros
Published: January 2022

This chapter explores ways of practising sociology online in ways that benefit rather than alienate the discipline from itself, its practitioners, and its audiences. It discusses multiple challenges that sneak up slyly, including the ability to translate sociological research into social media content and the allure of narcissistic self-promotion or institutional pressure to ply scholarly wares online as enterprising brand ambassadors. It also sketches out a plan for engaging with social media in ways that do not compromise sociological rigour or academic solidarity. The chapter explains how existing categories obscure a diffuse publicness that characterizes the use of social media by sociologists, even when no explicit attempt is being made to pursue this. It refers to the decentring of outputs, expertise, and knowledge that requires a firmer grounding in the institutional conditions in which sociologists work.
Imitations of Celebrity
Authors: Merck Mandy
Published: January 2022

One of the most abiding anxieties about contemporary celebrity culture is that it encourages the emulation of impossible or unsuitable role models.  While moralists on the right and left denounce the inculcation of false values, absurd ambition and political misjudgement supposedly caused by celebrity imitation, film scholars have defended the creativity in fans’ mimetic responses to the stars they admire.  As Fannie Hurst’s 1933 novel Imitation of Life and its 1934 and 1959 film adaptations suggest, both the ontological and the ethical status of ‘imitation’ vary, putting into question any simple condemnation of the ‘imitation of life’.
Faking Spirit Possession: Creating ‘Epistemic Murk’ in Bahian Candomblé
Authors: Port Mattijs van de
Published: January 2022

In the Afro-Brazilian candomblé religion, faking spirit-possession is a well documented phenomenon. The practice is associated with young male homosexuals, and has often been understood as a kind of gender bending: dressed in the attire of female spirits, the imposters dance in front of an appreciative audience. This chapter seeks to complicate the analysis of the phenomenon by highlighting the multiple interpretative frames that come together in Candomblé ceremonies. In their co-presence these frames produce an overall uncertainty about the real of things, a blurring of clear-cut boundaries between fiction, fact, performance, imagination, reality. This ‘epistemic murk’, as Michael Taussig once called it, contributes to an awareness of the mysteries that are at the core of Candomblé’s religious practices. It signals that the human capacity to grasp the world is limited, and that there is a beyond to our knowing.
Postscript: Thinking with Imposters – What Were They Thinking?
Authors: Agnes Forrest Carter , Bean Civet Coffee , Cuckoo Iansá , Oxum Sarah Jane , Meegeren Han van , Rosenhahn David , Stapel Diederik , Suárez Jorge Enrique Briceño
Published: January 2022

The authorship of the postscript is unclear. It is, allegedly, written by a roster of Imposters that feature in the previous chapters of the volume. Yet, it also contains the transcript of a conversation between Harold Garfinkel, Erving Goffman and Alan Sokal. And, in a twist, the editors of the volume themselves appear as part of this exchange. Hence, the ambiguous identity of the authorial ‘we’, underscoring the indeterminancy characteristic of the imposter phenomenon.
Despite the lack of a clear provenance, the postscript provides a bookend to a volume teeming with examples of the significance of the imposter for rethinking social theory. The postscript additionally suggests that the figure of the imposter offers a challenge to the very idea of social theory. The figure of the imposter requires us to think and see social and cultural forms differently.
Introduction
Authors: Lee Micky , Chung Peichi
Published: January 2022

The introductory chapter uses esports in Asia as an example to problematise the premises of the book: the blurred boundary between work and play; the uneven technology development and adaptation in Japan and the two Koreas; the presumed cultural differences between Asian and western cultures. The chapter then lays out the two aims of the book: the first aim of the book is to use three approaches—political economy, cultural studies, and science and technology studies—to examine the complexity of media technologies. The second aim is to discuss how media technologies in Asia illustrate the peculiar geopolitical relations between Japan, South Korea, and North Korea. The chapter then examines the four pairs of pull and push factors that shaped 20th century geopolitics in the Northeast Asian region: colonisation and independence, war and reconstruction, westernisation and indigenisation, as well as state-led development and globalisation. It then reviews current literature on media technologies in Northeast Asia by arguing that there is a lack of conversation between those who work on technological development at the macro level and those who work on technology use at the micro level. It the summarizes the key arguments of the ten collected essays.
‘For Japan Only?’ Crossing and Re-inscribing Boundaries in the Circulation of Adult Computer Games
Authors: Galbraith Patrick W.
Published: January 2022

This chapter considers how and why 'Japan' comes to matter in the circulation of games in a globalised world by examining the consumption of adult video games inside and outside Japan. Despite the export of Japanese video games abroad, adult computer games are often seen to be distinctively 'Japanese.' This chapter argues that adult video games are a niche genre; producers and players form a close-knitted community that is suspicious of non-Japanese out of the fear that the Western media will widely report such games. Western reports about such games have led the international community to put pressure on the Japanese government to stamp out such genre. While some in the adult game community believe that it'd be the best if the game would only be played by Japanese inside the country, others are keen to expand the community outside Japan. The chapter concludes by suggesting the need to go beyond national and nationalising discourse to see the nuance of interactions within national borders and exceeding them.
Hyperreal Peninsula: North Korea’s Nuclear Cinema and South Korea’s Digital Revolution
Authors: Shim Elizabeth
Published: January 2022

Drawing from the televisual simulacra of North Korea weapons provocations and projections of regime power, this chapter examines the emergence of a video-mediated nuclear North Korea in the new millennium within the broader frame of networked digital technologies that have facilitated South Korea media flows into the country. Military display and the more recent emergence of the leadership’s nuclear diplomacy can be evaluated as simulation, and is interrogated in the explicit context of a cultural moment when the people of the territorialised and retrenched nation-state of 21st-century North Korea are receptive to South Korean popular culture and neoliberal productions. This chapter highlights the opportunities and constraints of global media and information flows for the newly emerging society of 'transnational Korea' being built on capitalist imperatives and shaping hierarchical relations. Within this configuration, military display simulates state power at a historical moment when South Korea televisual media is the driving force behind prohibited North Korea leisure time. Mediated technologies then, and their capacity to meticulously steer the social, illustrate the uneasy relationship between work and play, state sovereignty and global flow.
Representations of Play: Pachinko in Popular Media
Authors: Amano Keiji , Rockwell Geoffrey
Published: January 2022

This chapter argues that there are at least three phases of the pachinko industry in Japan; popular media such as films and novels reflect how filmmakers and novelists saw the game differently in these three phases. The first phase commenced after the end of WWII, at that time pachinko was a family; the game was seen as idle pursuits, contrasting the work ethics expected for adults to rebuild the country. The second phase took place during the economic boom from the 1970s to the 1980s, at that time the industry became more organised but opaque. Many believe that pachinko owners are gangsters or Koreans who were sympathetic of the North Korean government. During this period, pachinko parlours serve as the glamourous backdrops of films. The third phase coincided with the post-economic bubble era, pachinko was transformed from a mechanical technology to a digital one. The players’ skills are no longer relevant, the game became one of chance. The transformation of the technology serves as a metaphor for life’s randomness; those who lose in this random game is like populations who were left behind in the post-bubble economy.
Social Media and the Automatic Production of Memory
Authors: Jacobsen Ben , Beer David
Published: January 2022

Social media platforms hold vast amounts of biographical data about our lives. They repackage our past content as ‘memories’ and deliver them back to us. But how does that change the way we remember? Drawing on original qualitative research as well as industry documents and reports, this book critically explores the process behind this new form of memory making. In asking how social media are beginning to change the way we remember, it will be essential reading for scholars and students who are interested in understanding the algorithmically defined spaces of our lives.

Experimental Demonstration of Polarization Entanglement from a Spatiotemporally Incoherent Source
Authors: Li Cheng , Braverman Boris , Kulkarni Girish , Boyd Robert W.
Published: January 2022

Spontaneous parametric down conversion (SPDC)-based sources of photonic entangled states are usually generated using coherent pump fields. For temporal, spatial, and polarization degree of freedom, the down-converted light entanglement is limited by the coherence of the pump in the same degree of freedom. However, the effect of pump coherence on the entanglement in a different degree of freedom remains largely unexplored. Here we experimentally demonstrate the generation of polarization entanglement from SPDC pumped by a light emitting diode (LED), a spatiotemporally incoherent pump. The two-photon state is found to have a concurrence of 0.562 and purity of 0.647.
