Embeddedness in social networks is increasingly seen as a root cause of human achievement, social stratification, and actor behavior. In this article, we review sociological research that examines the processes through which dyadic ties form, persist, and dissolve. Three sociological mechanisms are overviewed: assortative mechanisms that draw attention to the role of actors' attributes, relational mechanisms that emphasize the influence of existing relationships and network positions, and proximity mechanisms that focus on the social organization of interaction.

We develop the concept of the distant future as a new way of seeing the future in collective efforts. While a near future is represented in practical terms and concerned with forming expectations and goals under conditions of uncertainty, a distant future is represented in stylized terms and concerned with imagining possibilities under conditions of ambiguity. Management research on future-oriented action has developed around problems of the near future. To explore distant futures, we analyze the case of geoengineering, a set of planetary-scale technologies that have been proposed as solutions to the threat of climate change. Geoengineering has increasingly been treated as if it were a reality, despite continued controversy and in the absence of any implementation. We find that societal-level imaginaries that were built on deeply-held moral bases and cosmologies underpinned the conception of geoengineering, and that a dialectic process of discursive attempts to reconcile oppositional imaginaries increased the concreteness and credibility of geoengineering so that it increasingly has been treated as an 'as-if' reality. We suggest that distant futures orient collective efforts in distinctive ways, not as concrete guides for action but by expressing critiques and alternatives, that can become treated as 'as-if' realities. Imagine a new world where a vast wall of mirrors is erected in outer space to protect the earth from the heat of the sun. Imagine using US Navy warships to blast trillions of tiny particles high up into the sky or deploying a fleet of modern 'steam' ships into the seven seas to spray salt water into the air 24 hours a day to create better clouds. Or how about covering vast stretches of desert with sheets of white plastic to reflect light back to the sun? What about dumping billions of tons of iron filings into the sea or building millions of chemically coated plastic trees to suck up carbon dioxide from the air? … This may all sound like preposterous science fiction-yet the debate about 'geo-engineering' a way out of catastrophic levels of climate change seems to be gaining grip in several parts of the world.

We advance interactionist perspectives on how organizational structures emerge in new issue domains. Our study is grounded in field data collected over 18 months at a large biomedical company that sought to become more sustainable. Over that period, some sustainability-related issues became firmly embedded in formal structures and procedures, while others faltered. We identify the quality of situational interactions among organizational members as the engine behind the structuring of organizational sustainability efforts. Successful interactions generated traces of attention, motivation, knowledge, relationships, and resources that linked fleeting interactions to emergent organizational structures. Our findings point to the importance of internal advocates and distributed processes at middle and lower levels for developing organizational structures, and we show that advocates’ interests, commitments, and identities are altered in the course of repeated interactions, as are the political resources available to them. Paying attention to situation-level interactions thus results in a more dynamic view of the emergence of formal structures through political processes. We develop a process model that informs structuration perspectives on organizational change by showing how social interaction dynamics can account for divergent levels of structuring within the same domain. The model also advances political perspectives on organizational change by unpacking the situational underpinnings of advocacy efforts and collective mobilization around issues.

The rise and institutionalization of corporate social responsibility (CSR) in sport is captured in a growing body of work in sport management. This literature suggests professional teams should be strategic in their approaches-matching internal resources with external needs-but we lack an understanding of the processes and mechanisms in the evolution to more strategic CSR, as well as specific practices that characterize these approaches. Further, by focusing on broad trends in how and why teams are adopting CSR, we miss the opportunity to learn from teams with innovative and authentic CSR approaches. To address these gaps, this article uses a qualitative case-study approach to examine how one professional team in the U.S.-the Detroit Lions-evolved their CSR to a more strategic and authentic partnership-focused model. Our findings point to key process steps and mechanisms in the decision making around, and implementation of, this approach, including the role of organizational structure, leadership, and community partnerships. We draw out themes around these central partnerships and highlight best practices. In offering a more nuanced understanding of professional sport CSR process and practice, we contribute to the literature on CSR in sport, sport-community partnerships, and sport and city revitalization.

Sorption and desorption equilibria of phenanthrene with respect to three different types of geosorbents were measured, as were the rates of desorption and biological mineralization of this representative hydrophobic organic contaminant. The chemical nature of the organic matter associated with each geosorbent was characterized using solid state 13C‐NMR spectrometry. The results of these studies reveal that both the desorption behavior and the microbial bioavailability of the sorbed contaminant are influenced by the physicochemical character of the organic matter. The more reduced and condensed the organic matter, the greater the extent of sorption‐desorption hysteresis, the slower the desorption rate, and the less readily bioavailable the sorbed contaminant. These observations are consistent with projections predicated on a dual reactive domain model introduced earlier to describe the sorptive reactivities of different types of soil/sediment organic matter with hydrophobic organic contaminants.
