The social and political conditions actuated by 9/11 have been a major catalyst for new literature, television and film about South Asians and Muslims in America. Stemming from a 2001 speech by then president George W. Bush, the concept of the “War on Terror” has served to rationalize the domestic regulation of Muslims, while also validating the need for US imperialist and capitalist expansion. Where US government discourse highlights first-person narratives that figure America as a benevolent global protector of freedom and democracy, South Asian American fictional and non-fictional narratives posit critiques of Islamophobia and the US security state. Spanning a breadth of genres and styles, including the paradigmatic 9/11 novel, the bildungsroman, comedic satire, dramatic monologue, magic realism, documentary film, and urban fiction, South Asian American literature and media highlight narratives of interfaith and cross-racial solidarity. The imaginary worlds of these texts confront the injustices of US imperialism and the global War on Terror for Muslim communities both in the United States and abroad. At the same, South Asian American representation engaged with the impacts of post-9/11 politics and society has enriched understanding of the complex lived experiences of Pakistani and Bangladeshi Americans, as well as those of Indian Americans who are Muslim or trace their ancestry to the Sikh-majority state of Punjab. By centering the perspectives of those communities most affected by detention, xenophobia, and surveillance, post-9/11 South Asian American literature and media reveal how the exigencies of history produce new forms of narrative and cultural practice.
Rioting in the United States since 1800 has adhered to three basic traditions: regulating communal morality, defending community from outside threats, and protesting government abuse of power. Typically, crowds have had the shared interests of class, group affiliation, geography, or a common enemy. Since American popular disorder has frequently served as communal policing, the state—especially municipal police—has had an important role in facilitating, constraining, or motivating unrest.
Rioting in the United States retained strong legitimacy and popular resonance from 1800 to the 1960s. In the decades after the founding, Americans adapted English traditions of restrained mobbing to more diverse, urban conditions. During the 19th century, however, rioting became more violent and ambitious as Americans—especially white men—asserted their right to use violence to police heterogeneous public space. In the 1840s and 1850s, whites combined the lynch mob with the disorderly crowd to create a lethal and effective instrument of white settler sovereignty both in the western territories and in the states. From the 1860s to the 1930s, white communities across the country, particularly in the South, used racial killings and pogroms to seize political power and establish and enforce Jim Crow segregation. Between the 1910s and the 1970s, African Americans and Latinos, increasingly living in cities, rioted to defend their communities against civilian and police violence. The frequency of rioting declined after the urban rebellions of the 1960s, partly due to the militarization of local police. Yet the continued use of aggressive police tactics against racial minorities has contributed to a surge in rioting in US cities in the early 21st century.

Cities themselves function as media of communication. They are places where messages are created, carried, and exchanged by structures, infrastructures, and people. Urbanity is an age-old phenomenon undergoing radical transformation as developing means of communication redefine traditional notions of place and space. Urban communication meshes population density, technology and social interaction. Urban communication, like urban studies, is an interdisciplinary field that provides a fresh perspective from which to view the city and its transformation. The communication lens offers valuable perspectives and methodologies for the examination of urban and suburban life. It conceptualizes the city as a complex environment of interpersonal interaction, a landscape of spaces and places that shape human behavior, and an intricate technological environment.
The development of urban communication research and activities is traceable from the early works a diverse group of urbanists to more current research programs conducted by communication scholars. Urban communication foregrounds communication in the study of the urban landscape. The unique patterns and needs of urban dwellers and communities are examined in an age where cities are layered with media technologies. An increasing number of technologies enable information from the digital world to be layered onto the physical world through augmented realities, thereby altering the person–environment relationship by creating spaces in which users interact with their physical surroundings through digital media. The future of cities is increasingly influenced by media technology. Cities are global, connected, inclusive, livable, green, sustainable, mega, and smart. Cities have been identified as communicative cities. There are many ways of looking at communication and cities and the history and broad parameters of the growing area of urban communication.
The transformation of post-industrial American life in the late 20th and early 21st centuries includes several economically robust metropolitan centers that stand as new models of urban and economic life, featuring well-educated populations that engage in professional practices in education, medical care, design and legal services, and artistic and cultural production. By the early 21st century, these cities dominated the nation’s consciousness economically and culturally, standing in for the most dynamic and progressive sectors of the economy, driven by collections of technical and creative spark. The origins of these academic and knowledge centers are rooted in the political economy, including investments shaped by federal policy and philanthropic ambition. Education and health care communities were and remain frequently economically robust but also rife with racial, economic, and social inequality, and riddled with resulting political tensions over development. These information communities fundamentally incubated and directed the proceeds of the new economy, but also constrained who accessed this new mode of wealth in the knowledge economy.
(East and Southeast) Asian Canadian literature has consistently been preoccupied with the transpacific: from its lived spaces, its imagined ones, and its hybrid literary constructions. This body of literature includes narratives of arrival, autobiographical texts, historiographic novels, magical realist fiction, and experimental poetry. While these texts have usually been read through historical frameworks, thinking through them spatially enables us to understand and trace the alternate geographies of mobility, belonging, and cultural change beyond the project of the Canadian nation. These texts are predicated on transnational spaces of commerce and labor, trauma and resistance, refuge and liminality, and mobility and materiality. They reflect and produce the complex and overlapping trajectories of communities and individuals from East and Southeast Asia. From fictions of Chinatown to testimonies of racist dispersal and exclusion, refugee narratives to speculative decolonial futures, Asian Canadian literature has shaped both rural and urban Canadian spaces and their transnational and local textures. Thinking through the transpacific spaces in the literature points to the ways in which racist and exclusionary policies have shaped the landscapes and social spaces of the nation whether through immigration laws or forcible dispossession and internment. Yet, it also gives rise to the possibilities of new collectivities and communities within and beyond the nation-state. In the face of unequal globalization and movements of labor and capital, this mode of analysis points to possible indigenous and diasporic solidarities and place-making. Contemporary texts from Asian Canadian writers also evince a consciousness of Canadian bioregions and the confrontation of extraction economics that allows for a discussion of intersectionality in the context of environmental humanities and ecocriticism.

The University of Wisconsin-Madison has been a prominent producer of doctorates in African history since 1963. As of 2017 the institution had granted more than 110 degrees. Philip D. Curtin and Jan Vansina, both pioneers in launching the field, led the program until 1975 and were joined in 1969 by Steven Feierman. Together, they supervised an initial cohort of graduates, several of whom became leaders of the then still-formative field, particularly in its methodological infrastructure, as well as in economic and demographic history, slavery in Africa and the Atlantic slave trade, and medical history. The distinguishing features qualifying a diverse array of individual intellectual trajectories as a coherent “school” include a focus on epistemologically historical approaches anchored in the intellectual perspectives of Africans as historical actors and often also as they engaged broader commercial Atlantic and Indian Ocean and world contexts; smaller numbers of more recent doctorates had subsequently sustained these orientations.
Former graduates of the program, William W. Brown, David Henige, and Thomas T. Spear, returned after 1975 to update this framework by bringing social theory and cultural history to bear on the African historical actors at the program’s core. Since 2005, a third generation of faculty members, Neil Kodesh, James Sweet, and Emily Colacci (all students of Wisconsin PhDs teaching at other institutions), have added contemporary approaches to the Wisconsin school’s continuing commitment to Africans’ distinctive epistemologies as they engaged the flows of modern global history. Professionally, Madison graduates have, accordingly, led the ongoing effort to bring Africa in from its initial marginality—as the continent seen as uniquely without a history—into the historical discipline’s core. An aphoristic summary of the Wisconsin legacy might be “Africans’ worlds and Africans in the world.”

The only youth-led national civil rights organization in the 1960s in the United States, the Student Nonviolent Coordinating Committee (SNCC), grew out of sit-ins, with the base of its early membership coming from Black colleges. It became one of the most militant civil rights groups, pushing older organizations to become more aggressive. Under the tutelage of the experienced activist Ella Baker, it emphasized developing leadership in “ordinary” people. Its early years were dominated by direct action campaigns against White supremacy in the urban and Upper South, while internally, SNCC strove to actualize the Beloved Community. Later it specialized in grassroots community organizing and voter registration in dangerous areas of the Deep South. Its Freedom Summer campaign played a significant role in radicalizing young activists. SNCC, in general, acted as a training ground and model for other forms of youth activism. Notwithstanding its own issues with chauvinism, SNCC was open to leadership from women in a way that few social change organizations of the time were.
Theoretical Perspectives on Age Differences in Brain Activation: HAROLD, PASA, CRUNCH—How Do They STAC Up?
Sara B. Festini, Laura Zahodne, and Patricia A. Reuter-Lorenz
Cognitive neuroimaging studies often report that older adults display more activation of neural networks relative to younger adults, referred to as overactivation. Greater or more widespread activity frequently involves bilateral recruitment of both cerebral hemispheres, especially the frontal cortex. In many reports, overactivation has been associated with superior cognitive performance, suggesting that this activity may reflect compensatory processes that offset age-related decline and maintain behavior. Several theories have been proposed to account for age differences in brain activation, including the Hemispheric Asymmetry Reduction in Older Adults (HAROLD) model, the Posterior-Anterior Shift in Aging (PASA) theory, the Compensation-Related Utilization of Neural Circuits Hypothesis (CRUNCH), and the Scaffolding Theory of Aging and Cognition (STAC and STAC-r). Each model has a different explanatory scope with regard to compensatory processes, and each has been highly influential in the field. HAROLD contrasts the general pattern of bilateral prefrontal activation in older adults with that of more unilateral activation in younger adults. PASA describes both anterior (e.g., frontal) overactivation and posterior (e.g., occipital) underactivation in older adults relative to younger adults. CRUNCH emphasizes that the level or extent of brain activity can change in response to the level of task demand at any age. Finally, STAC and STAC-r take the broadest perspective to incorporate individual differences in brain structure, the capacity to implement functional scaffolding, and life-course neural enrichment and depletion factors to predict cognition and cognitive change across the lifespan. Extant empirical work has documented that compensatory overactivation can be observed in regions beyond the prefrontal cortex, that variations in task difficulty influence the degree of brain activation, and that younger adults can show compensatory overactivation under high mental demands. Additional research utilizing experimental designs (e.g., transcranial magnetic stimulation), longitudinal assessments, greater regional precision, both verbal and nonverbal material, and measures of individual difference factors will continue to refine our understanding of age-related activation differences and adjudicate among these various accounts of neurocognitive aging.

The Internet and social media increasingly are becoming sources about the African past and present in ways that will influence to some extent how history will be learnt and the form that methods of historical research will take. Social media have increasingly dislodged print journalism as “the first rough draft of history” and tended to democratize and hasten information sharing and communication. Historians are working through difficult debates about the Internet as a source archive, the usability of websites, and related matters. The debate over online resources and their use in historical and other studies on one level remains unresolved. Nevertheless, online sources add another rich layer to narratives, stories, and perspectives that are already being recorded or told, and in this regard they will add to the storehouse of empirical data to be crunched by future historians.

Space weather is a collective term for different solar or space phenomena that can detrimentally affect technology. However, current understanding of space weather hazards is still relatively embryonic in comparison to terrestrial natural hazards such as hurricanes, earthquakes, or tsunamis. Indeed, certain types of space weather such as large Coronal Mass Ejections (CMEs) are an archetypal example of a low-probability, high-severity hazard. Few major events, short time-series data, and the lack of consensus regarding the potential impacts on critical infrastructure have hampered the economic impact assessment of space weather. Yet, space weather has the potential to disrupt a wide range of Critical National Infrastructure (CNI) systems including electricity transmission, satellite communications and positioning, aviation, and rail transportation.
In the early 21st century, there has been growing interest in these potential economic and societal impacts. Estimates range from millions of dollars of equipment damage from the Quebec 1989 event, to some analysts asserting that losses will be in the billions of dollars in the wider economy from potential future disaster scenarios. Hence, the origin and development of the socioeconomic evaluation of space weather is tracked, from 1989 to 2017, and future research directions for the field are articulated. Since 1989, many economic analyzes of space weather hazards have often completely overlooked the physical impacts on infrastructure assets and the topology of different infrastructure networks. Moreover, too many studies have relied on qualitative assumptions about the vulnerability of CNI. By modeling both the vulnerability of critical infrastructure and the socioeconomic impacts of failure, the total potential impacts of space weather can be estimated, providing vital information for decision makers in government and industry.
Efforts on this subject have historically been relatively piecemeal, which has led to little exploration of model sensitivities, particularly in relation to different assumption sets about infrastructure failure and restoration. Improvements may be expedited in this research area by open-sourcing model code, increasing the existing level of data sharing, and improving multidisciplinary research collaborations between scientists, engineers, and economists.
