How can I Be as attractive as a Fitness YouTuber in the era of COVID-19? The impact of digital attributes on flow experience,satisfaction, and behavioral intention

In the past decade, the social media platform has dramatically changed individuals’ daily activities in real life and on the Internet, including shopping, socialization, entertainment, study, and even health and fitness. In the era of COVID-19, particularly, consumers tend to rely more on digital attributes of social media platforms for their decision-making process by reducing the physical touchpoint. Responding to this ongoing trend, this study investigates how fitness YouTube channel attributes and fitness YouTuber attributes influence flow experience, satisfaction, and behavioral intention of YouTubers who work out at home via a fitness YouTube channel during the COVID-19 pandemic. Based on the social media literature and the cognitive appraisal theory, this research formulates a research model that specifies the influence of three dimensions of fitness YouTube channel attributes (i.e., social interaction, information quality, and visual content) and three dimensions of fitness YouTuber attributes (i.e., social attractiveness, physical attractiveness, and attitude homophily) on flow experience, YouTube channel satisfaction, and behavioral intention in the context of YouTube. This study recruited participants in the United States who currently work out via a fitness YouTube channel through three waves of data collection during the COVID-19 era. The empirical results revealed that flow experience was significantly affected by information quality, visual content, and physical attractiveness. Also, YouTube channel satisfaction was significantly affected by social interaction, information quality, and visual content. Lastly, behavioral intention was significantly affected by flow experience and YouTube channel satisfaction. Based on the findings, this study proposes meaningful implications for the extant literature and social media industry during the COVID-19 pandemic.

Vinyl record: a cultural icon

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.     

Striking a Balance Between Rules and Principles-based Approaches for Effective Governance: A Risks-based Approach

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).

From Brighton beach to blogs: exploring food-related nostalgia in the Russian diaspora

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.     

How the Netherlands became a bicycle nation: Users,firms and intermediaries, 1860–1940

In 1925, the Netherlands was a country of cyclists and cycle producers, as all classes cycled and almost all cycles were produced domestically. The bicycle was not a Dutch invention and the country had an open economy, and this raises the question ‘how did the Netherlands become a bicycle nation?’ This article investigates the interactions of users, firms and intermediaries from 1860 to 1940 and how these impacted the bicycle, its production and its use. Furthermore, it analyses knowledge flows and the roles of intermediaries. It illustrates changes in activities and the relevance of interactions between users, firms and intermediaries, and the effects of World War I. It shows how user organisations created an infrastructure and culture which made cycling Dutch. Firms created a cartel which produced bicycles that were wanted and used by all Dutch, as they were made in the Netherlands.     

An emotional economy of mundane objects

This article illuminates the affective potentialities of objects. We examine the circulation of Kurdish music cassettes in Turkey during the restrictive and strife-laden period of the 1970s, 1980s, and 1990s. We find that the practices comprising circulation – recording, hiding, playing, and exchanging cassettes – constituted tactical resistance and generated communal imaginaries. We illuminate the “emotional economy” that is animated by a mundane object: the cassette, through its circulation, becomes saturated with emotions, establishes shared emotional repertoires, and habituates individuals and collectives into common emotional dispositions. Cassettes thus play a part in shaping and reinforcing an emotional habitus that accompanies the emergence of a sense of “us,” the delineation of the “other,” and the relationship between the two. We thus demonstrate the entwinement of materiality and emotions, and examine how this entwinement generates emotional structures that shape and perpetuate the imagining of community as well as the enactment of resistance.     

Service Quality Expectations: Exploring the Importance of SERVQUAL Dimensions from Different Nonprofit Constituent Groups

Given the multiplicity of “customers” in the nonprofit sector, the need for nonprofits to ensure that quality service delivery matches customer expectations is difficult yet paramount. Nonprofit organizations serve several constituent groups: the service recipient, donor, volunteer, and general public at large. While each constituent group may not be perceived as a customer in the general sense, each group is making quality assessments that may affect performance evaluations, donations, volunteerism, and brand equity decisions. Hypothesis support was found, distinguishing between the importance of the different SERVQUAL dimensions and the perspective roles played within the nonprofit scenarios. Respondents playing the role of volunteer rated Empathy and Assurance highest and Tangibles lowest. Respondents playing the role of donor rated Reliability and Tangibles highest and Empathy lowest. Respondents playing the role of recipients rated Empathy and Responsiveness highest and Tangibles lowest. Finally, respondents playing the role of volunteer rated Assurance and Reliability highest and Tangibles lowest.
