In this paper, we use the case of the vinyl record to show that iconic objects become meaningful via a dual process. First, they offer immersive engagements which structure user interpretations through various material experiences of handling, use, and extension. Second, they always work via entanglements with related material ecologies such as turntables, speakers, mixers, and rituals of object care. Additionally, these engagements are complimented by a mediation process which emplaces the vinyl historically, culturally, spatially, and also politically, especially in the context of digitalization. This relational process means that both the material affordances and entanglements of vinyl allow us to feel, handle, experience, project, and share its iconicity. The materially mediated meanings of vinyl enabled it to retain currency in independent and collector’s markets and thus resist the planned obsolescence and eventually attain the status of celebrity commodity with totemic power in music communities. This performative aspect of vinyl markets also means that consumers read closely the signals and symbols regarding vinyl’s status, as its various user groups and champions try to interpret its future, protect, or challenge its current position. Vinyl’s future, and the larger expansion of pressing plants and innovative turntable production around it, largely depend on processes of cultural and status mobility. In the current phase of market expansion, vinyl’s status might be challenged by its own success. Neither a fashion cycle phenomenon, nor simple market conditions explain vinyl’s longevity. Rather, cultural contextualization of vinyl as thing and commodity is crucial for avoiding symbolic pollution and retaining sacred aura.  相似文献

This study presents a model of how consumers respond to an attachment trauma for which they feel a substantial degree of personal responsibility. The model is derived from an analysis of the lived experiences, stories, and observations of divorced single mothers, who have experienced an attachment trauma as a consequence of a marriage break down. The trauma involves a dramatic loss of normalcy and certainty, accompanied by negative emotions, such as fear and uncertainty, stress and grief, self‐castigation, guilt and shame, and rumination and depression. In an effort to recover from the trauma and return to healthier emotional states, consumers adopt amelioration strategies characterized by self‐compassion, self‐care, and the (re)building of self‐capabilities. Consumption practices—restorative and transformative in nature—facilitate each strategy, as consumers strive to regain the confidence, sense of control, and equilibrium destroyed by the trauma. The model arguably provides a useful lens to understand other kinds of traumatic events where a sense of heightened personal responsibility prevails.  相似文献

This research presents a qualitative exploration of food-related nostalgia experienced by individuals from Russia and the former Soviet Union in the context of diasporic waves. By varying time and space dimensions associated with nostalgia, the analysis is conceptualized around three “locations”: (1) Russia and the Commonwealth of Independent States, (2) Brighton Beach, New York, and (3) cyberspace. Weblogs, demonstrated here to be objects of inquiry, are analyzed according to their nostalgia content, social connections, and community interaction. Nostalgic evocation through traditional cuisine is evident in all three settings. Personal, interpersonal, and cultural nostalgia are apparent in web content, demonstrating a technological role in the creation, sharing, and dissemination of nostalgia. Implications of the study relate to the sociology of food and interdisciplinary food studies, culinary tourism, online and offline marketing, and product distribution into ethnic and international markets.  相似文献

Several recent studies and initiatives have emphasized the importance of a strong ethical organizational DNA (ODNA) to create and promote an effective corporate governance culture of trust, integrity and intellectual honesty. This paper highlights the drawbacks of an excessively heavy reliance on rules-based approaches that increase the cost of doing business, overshadow essential elements of good corporate governance, create a culture of dependency, and can result in legal absolutism. The paper makes the case that the way forward for effective corporate governance is to strike an optimal balance between rules-based and principles-based approaches. The recent corporate scandals have demonstrated that the ethical ODNA is critical to the driving force and basis of legal and regulatory requirements. Effective governance means adhering to ethical principles, not merely complying with rules, and is a crucial guardian of a firm’s reputation and integrity. It is through an effective corporate governance program (that is, one that optimally captures and integrates the appropriate aspects of rules-based and principles-based approaches, and identifies and assesses the related risks) that an organization can reconfigure its ODNA for improved performance. Focusing on the ethical ODNA as the basis of new governance measures provides an opportunity to develop a competitive advantage as it represents a potential source of differentiation, strengthens the relationship with all stakeholders of the organization by building a culture of trust and integrity, and re-instills investor confidence. This paper employs dialectical reasoning that links the ODNA through principles-driven rules in developing a risks-based approach. A comparison from a risk assessment perspective between rules-based and principles-based approaches is presented. Although there have been few applications employing dialectical reasoning in business research, this methodology can be extremely useful in isolating ethical issues and integrating them into the business process. The risks-based approach captures the benefits of both rules-based and principles-based approaches, and incorporates trust-based principles such␣as solidarity, subsidiarity and covenantal relationships.Sundera Arjoon is a Senior Lecturer in Ethics at the Department of Management Studies, The University of the West Indies, Trinidad, He has served as Head of Department (2002–2005) and as Deputy Dean of the Faculty of Social Sciences (1996–2002).

Abstract

The purpose of this paper is to develop detailed insight into loyalty among football fans of Hibernian FC, moving beyond typologies to a more socially grounded approach. Issues explored include patterns of consumption, distinctions between fan groups, and antecedents of loyalty. The origins and development of the club are evaluated, and consumer fanaticism, football fan loyalty, consumption behaviour, and the sociological impact of fan communities are discussed. Data were collected using a variety of methods, including participant observation, in-depth interviews, and analysis of websites and fan forums. Key findings relate to the impact of family and community influences on loyalty, initial experiences of developing associations with the club, through to the impact of socialisation, and the lived experience of being a supporter. A supporter matrix is constructed as a portrayal of the loyalty found at the club. A range of theoretical implications is considered, and the matrix promoted as a tool for understanding loyalty in clubs with similar social structures and community connections.  相似文献

The return of xenophobic and racist movements in many countries known for their multiculturalism and tolerance signifies the resurgence of nationalism, marked by hostility to outsiders and cultural apartheid. The nation has been portrayed as an imagined community, and the terms nation and nationality have been acknowledged to be difficult to define. Despite its abstract nature, nationalism still commands profound political and emotional legitimacy in modern society and remains the most cruel and powerful force in politics. It is associated with the perception of national superiority, an orientation toward dominance, a collective grievance against foreigners, and a downward comparison of other nations. It shows an evaluative negative bias and prejudice against other countries and a need for national power, bolstered by a hostility toward others. Against the backdrop of the violence, racism, and religious fanaticism of the contemporary world, this paper aims to enhance our understanding and add to the literature on the consumption and marketing of intercultural and interfaith understanding, human rights, diversity, and nationalism and explores implications therein for nonprofit organizations in this area, with an ethnographic study of one of the world’s largest Nichiren Buddhist organizations and of the ideology of Asia’s first Nobel-Laureate, poet, author, and philosopher, Rabindranath Tagore.  相似文献
