The work connects classic theories of selfing to the COVID-19 pandemic to make fresh connections between pandemic-induced trauma to the self and digital resources. This research introduces the concept of the “traumatized self” emerging from the COVID-19 pandemic in relation to digital disadvantage and digital hyperconnectivity. From Cooley’s original “looking glass self” to Wellman’s “hyperconnected” individualist self, social theories of identity work, and production of the self have a long and interdisciplinary history. In documenting this history, the discussion outlines key foci in the theorizing of the digital self by mapping how digital selfing and identity work have been treated from the inception of the internet to the epoch of the pandemic. The work charts the evolution of the digital selfing project from key theoretical perspectives, including postmodernism, symbolic interactionism, and dramaturgy. Putting these approaches in dialogue with the traumatized self, this research makes a novel contribution by introducing the concept of digitally differentiated trauma, which scholars can employ to better understand selfing processes in such circumstances and times.

This chapter explores the development of social science visualizations as cultural objects within art worlds. The research examines artworks as social science visualizations to show the importance of conducting analysis within distinctive social, institutional, and cultural environments. To make these arguments, the chapter outlines some of the key features of art worlds as they have been analyzed by cultural sociologists and anthropologists. We point out how cultures of reception and institutional intermediaries, such as museums, have historically shaped the construction of artworks, which are never produced or interpreted in a vacuum. The chapter closes with a call to expand both the application of social science visualizations and our understanding of such visualizations as subject to similar art world dynamics. Such visualizations, it is argued, constitute key components of social research practice increasingly oriented toward a digitally connected public hungry for visual interpretations of contemporary social developments.

While the literature on twice exceptionality is growing, it often focuses on twice exceptionality generally, overlooking within group differences that may create unique experiences for students. As such, there is a need to explicitly detail these differences to push the knowledge base forward. This chapter focuses on the unique needs and experiences of twice exceptional (2E) Black boys as they navigate K-12 schools. Further, this chapter details the ways in which school counselors may respond to their needs through comprehensive, antiracist school counseling practices. Finally, implications for policy and research are discussed.

This article addresses recent calls in the literature for advancing our understanding of public affairs consultants and their role conceptions. By testing and further exploring self-perceptions of public affairs consultants the study aims to offer new insight into how consultants define and view their occupational role.

The study draws on a nationwide survey with public affairs consultants in Sweden.

Four main role conceptions were identified (advocate, do-gooder, expert and intermediary). Further, the study tests how personal and professional characteristics correlate with different role conceptions, by viewing professional experience and consultants' selection of clients. Data also suggest that consultants' background in politics does not promote any specific role perception. Finally, the findings also show that how consultants choose clients is a divider in the industry, where some act as passive intermediaries while other take a more active role in their choice of clients.

The findings enhance our understanding of public affairs as a field, and specifically about the modelling of professional roles amongst consultants. The empirical results in this study show how contemporary role typologies needs to be extended to better capture the specificities of consultants' roles in public affairs. By addressing the issue of how consultants choose clients the study engages with the complex debate of whether consultants ought to act as objective or subjective agents and hence join the conversation on ethics in public affairs.

The curved and tribologically highly stressed surfaces of bearing components pose a major challenge for steel alloys or tribological resistant coatings like tetrahedral amorphous carbon (ta-C) coatings which in particular have an increased risk of delamination due to the significantly increased residual stresses. A possibility to prevent coating failure is the use of dopants while maintaining or even increasing tribological properties. This study aims to compare the tribological behavior of several doped diamond-like-carbon coatings with an undoped ta-C coating under varying slip conditions and Hertzian pressure up to 1800 MPa.

For this purpose, the tribological behavior was studied using of a ball-on-disc tribometer and a two-disc test rig under mixed/boundary conditions. The tests were conducted with coated specimens against uncoated 100Cr6 steel. Additionally, the influence of lubrication additives was studied due to the use of two fully formulated PAO-based oils, one without and one with molybdenum containing additives. The friction was measured in situ, and the wear was analyzed trough laser scanning microscopy and tactile measurement.

It was shown that the use of doped ta-C coatings exhibited a tendency for a more favorable tribological behavior compared to undoped ta-C coatings, with no general dependence on the lubricants used. The use of the most suitable coatings reduced the wear of the steel counter-body considerably.

To the best of the authors’ knowledge, this is the first approach of testing the tribological behavior of these doped ta-C coatings, developed for friction efficiency, in dependency on lubrication additives under the given load collective. The approach is relevant to determine whether the friction reduction and the wear inhibition of these coatings are suitable for higher contact pressures and load cycles.
