Occupational Diversity and Stratification in Platform Work: A Longitudinal Study of Online Freelancers

We focus on occupational diversity in platform-mediated work to advance conceptual and empirical insight into the occupationally embedded nature of platform labor. We pursue this focus in response to a prevailing tendency to treat platform workers as a homogeneous group, overlooking the unique demands, constraints, and practices rooted in specific professions. Such generalizations hinder both understanding of platform work and the development of sociotechnical systems that support differentiated occupational realities. To address this gap, we present a longitudinal analysis of 108 online freelancers spanning five occupational categories. We show that occupational context structures workers' capacity to interpret and navigate platformic management, shaping distinct experiences across four dimensions of platform work: self-presentation, flexibility, skilling, and platform work sustainability. To articulate how digital labor platforms' managerial control interacts with occupational embeddedness, we introduce the concept of platformic occupational stratification and discuss four mechanisms that explain its logic and implications for platform-mediated work. These insights contribute to CSCW by informing occupation-sensitive research and design approaches that directly engage with the specific opportunities and challenges rooted in workers' situated occupational agency in platform-mediated work.

Gender and Careers in Platform-Mediated Work: A Longitudinal Study of Online Freelancers

We advance gender-inclusive research within the CSCW field by investigating the long-term gendered experiences of online freelancers on digital labor platforms. The prevalence of gender-based inequalities has attracted significant attention within the CSCW community. Yet, insights remain limited on how these inequalities shape workers' long-term experiences on digital labor platforms. Through a five-year longitudinal study of 105 freelancers on Upwork, we reveal persistent gender disparities that influence workers' long-term work and career trajectories, raising concerns about the sustainability of platform-mediated work. We advance the ongoing dialogue on gender inclusivity in the community by introducing the concepts of career disempowerment and platform-mediated motherhood penalty and by offering research and design implications for CSCW to foster more sustainable, equitable platform work environments for all genders.

Decoding the Meaning of Success on Digital Labor Platforms: Worker-Centered Perspectives

What does work and career success mean for those who secure their work using digital labor platforms? Traditional research on success predominantly relies on organizationally-centric benchmarks, such as promotions and income. These measures provide limited insights into the evolving nature of work and careers shaped at the intersection of digital labor platform technologies and workers' evolving perspectives. Drawing on data from a longitudinal study of 108 digital labor platform workers on Upwork, we (1) identify seven dimensions of success indicators that reflect workers' definitions of success in platform-mediated work and careers, (2) delineate three dimensions of digital labor platforms mediating workers' experiences of success and (3) examine the shifting perspectives of these workers relative to success. Based on these findings, we discuss the implications of platform-mediated success in workers' labor experiences, marked by platformic management, standardization, precarity and ongoing evolution. Our discussion intertwines CSCW scholarship with career studies, advancing a more nuanced understanding of the evolving perspectives on success in platform-mediated work and careers.

Generative Artificial Intelligence in Healthcare: Ethical Considerations and Assessment Checklist

The widespread use of ChatGPT and other emerging technology powered by generative artificial intelligence (GenAI) has drawn much attention to potential ethical issues, especially in high-stakes applications such as healthcare, but ethical discussions are yet to translate into operationalisable solutions. Furthermore, ongoing ethical discussions often neglect other types of GenAI that have been used to synthesise data (e.g., images) for research and practical purposes, which resolved some ethical issues and exposed others. We conduct a scoping review of ethical discussions on GenAI in healthcare to comprehensively analyse gaps in the current research, and further propose to reduce the gaps by developing a checklist for comprehensive assessment and transparent documentation of ethical discussions in GenAI research. The checklist can be readily integrated into the current peer review and publication system to enhance GenAI research, and may be used for ethics-related disclosures for GenAI-powered products, healthcare applications of such products and beyond.

Platformization of Inequality: Gender and Race in Digital Labor Platforms

We contribute empirical and conceptual insights regarding the roles of digital labor platforms in online freelancing, focusing attention to social identities such as gender, race, ethnicity, and occupation. Findings highlight how digital labor platforms reinforce and exacerbate identity-based stereotypes, bias and expectations in online freelance work. We focus on online freelancing as this form of working arrangement is becoming more prevalent. Online freelancing also relies on the market-making power of digital platforms to create an online labor market. Many see this as one likely future of work with less bias. Others worry that labor platforms' market power allows them to embed known biases into new working arrangements: a platformization of inequality. Drawing on data from 108 online freelancers, we discuss six findings: 1) female freelance work is undervalued; 2) gendered occupational expectations; 3) gendered treatment; 4) shared expectations of differential values; 5) racial stereotypes and expectations; and 6) race and ethnicity as an asset. We discuss the role of design in the platformization and visibility of social identity dimensions and the implications of the reinforced identity perceptions and marginalization in digital labor platforms.
