Extensively ignored by the literature on the subject, recent interest in the fate of academic freedom in Africa is linked with shared concerns about the exploding nature of its societal crises. The collapse of political integration and social cohesion; the decline of the civil society and the implosion of conflicts; the rise of authoritarian, non-developmental populist regimes amid extreme poverty; and the worsening material conditions of the populations are major indications of such crises. Nowhere are these crises worse illustrated than in the universities where constrained funding, infrastructural collapse, massive brain drains and strained relations with the state inhibit the production of knowledge. This article reflects on the trajectory of the universities in postcolonial Africa. It draws on the national public universities in Nigeria and accounts for the changes and continuities underlying their performance against the backdrop of hostile material conditions and uncongenial political control, which not only remain disruptive but continue to undermine institutional autonomy and the integrity of scholarship in the universities across Africa.

We present analysis of the evolution of subsurface flows in and around active regions with peculiar magnetic configurations and compare their characteristics with the normal active regions. We also study the zonal and meridional components of subsurface flows separately in different polarity regions separately to better understand their role in flux migration. We use the techniques of local correlation tracking and ring diagrams for computing surface and subsurface flows, respectively. Our study manifests an evidence that the meridional component of the flows near anti-Hale active regions is predominantly equatorward which disagrees with the poleward flow pattern seen in pro-Hale active regions. We also find clockwise or anti-clockwise flows surrounding the anti-Joy active regions depending on their locations in the Southern or Northern hemispheres, respectively.

The Tiwanaku civilization (around AD 500–1100) originated in the Bolivian altiplano of the south-central Andes and established agrarian colonies (AD 600–1100) in the Peruvian coastal valleys. Current dietary investigations at Tiwanaku colonial sites focus on maize, a coastal valley cultivar with ritual and political significance. Here, we examine Tiwanaku provincial foodways and ask to what degree the Tiwanaku settlers maintained their culinary and agrarian traditions as they migrated into the lower-altitude coastal valleys to farm the land. We analyze archaeobotanical remains from the Tiwanaku site of Cerro San Antonio (600 m asl) in the Locumba Valley and compare them to data from the Tiwanaku site in the altiplano and the Rio Muerto site in the Moquegua Valley during the period of state expansion. Our findings show high proportions of wild, weedy, and domesticated Amaranthaceae cultivars, suggesting that Tiwanaku colonists grew traditional high-valley (2,000–3,000 m asl) and altiplano (3,000–4,000 m asl) foods on the lowland frontier because of their established cultural dietary preferences and Amaranthaceae's ability to adapt to various agroclimatic and edaphic conditions.

This article opens up new perspectives on gendered experiences of the Nazi era by exploring three individual women as case studies for subjective interpretations of German nationalism and modernity in the late 1930s and early 1940s. It focuses on Liselotte Purper, Ilse Steinhoff, and Margret Boveri, all of them journalists and photographers from Germany who sought adventure abroad and published books and articles about their trips back home. They were independent, hardworking, and pro-Nazi regime, though their professional and political principles played out differently. In tracing how these three women navigated and narrated their international journeys, I highlight that their quest for adventure, like those of others with a similar propensity for travel, involved primarily the pursuit of independence, individuality, and historical relevance. The range of their experiences and interpretations further draws attention to the complex relationship between collective identity and individual subjectivity under Nazism.

This article aims to explore the concept of patched/versioned musical works as creative ecologies. It identifies how the internet’s involvement in music creation and dissemination influences choices related to the release of such works. Throughout this writing, the author looks at the increasingly volatile structures surrounding recorded music in the early twenty-first century as a result of streaming platforms such as Spotify and video-based social media sites such as TikTok becoming the primary means for music consumption. It explores this volatility as a method for approaching the release of new music within dynamic musical ecosystems and looks at the growing art scene focusing on this way of working, drawing parallels between artistry and subscription-based services where content continually evolves over time.

The radiative mode of AGN feedback, operated through outflows, plays an essential role in the evolution of galaxies. Quasar outflows are detected as blue-shifted broad absorption lines in the UV/optical spectra of quasars. Thanks to the Sloan digital sky survey, 100,000 broad absorption line quasars are available now for ensemble statistical studies. This rich dataset has also enabled us to identify some peculiar cases of these sources. By quantifying the BAL fraction in radio-loud BAL quasars, our studies demonstrate a clear trend of increasing BAL fraction as the viewing angle approaches an edge-on orientation, favoring the orientation model of BAL quasars. Also, by contrasting the properties of BAL quasars with appearing and disappearing BAL troughs, our analysis suggests that the extreme variations in BAL troughs are driven by ionization changes.

This article examines how and why renowned Republican-era Chinese firms raised debt capital to finance their businesses by accepting savings deposits from ordinary people instead of borrowing from financial institutions. The article argues that in the absence of a powerful unitary state and centralized financial institutions, Chinese firms innovated sophisticated, decentralized financial instruments capable of amassing large quantities of capital from a broad host of depositors without the involvement of financial intermediaries. Savings deposits not only provided these firms with a cheaper and more flexible source of debt capital than that on offer from banks but also they fueled the Chinese economy by creating a sizable credit supply, a phenomenon that Chinese business and financial history scholarship focusing on the role of indigenous and modern banks has hitherto largely neglected.

Este artigo analisa a internacionalização de música moçambicana no âmbito da categoria de mercado “World Music”, durante o período de transição de um sistema de partido único e socialista, para um sistema multipartidário e liberal (1987-1994), enquadrado no processo de “construção da nação”. A análise comparativa de três casos – Orquestra Marrabenta Star de Moçambique, a canção “Baila Maria” do Grupo RM (Amoya), e os discos de Eyuphuro e Ghorwane (Real World Records) – confirma o recurso à World Music enquanto alternativa à letargia da indústria fonográfica do país e como veículo para promover internacionalmente a política musical de Moçambique durante a guerra civil.

Assuming responsibility and developing the tools needed for self- and political construction are hallmarks of the liberal imagination. A newly emerging subfield of performance studies—call it “performance capital studies”—teaches us what those tools are and how they may be put to use. “Performance” now comes to be seen as an exchange of cultural, legal, and identity capital retailing different forms of knowledge and power in the constitution and regulation of governance.

We show that, contrary to simple predictions, most AGNs show at best only a small increase of lags with increasing wavelength in the J, H, K, and L bands. We suggest that a possible cause of this near simultaneity from the near-IR to the mid-IR is that the hot dust is in a hollow bi-conical outflow of which we preferentially see the near side. In the proposed model sublimation or re-creation of dust (with some delay relative luminosity variations) along our line of sight in the hollow cone as the flux varies could be a factor in explaining the AGN changing-look phenomenon (CL). Variations in the dust obscuration can help explain changes in relationship of Hβ time delay on Luv variability. The relative wavelength independence of IR lags simplifies the use of IR lags for estimating cosmological parameters.

Political debate regarding trans youth’s access to gender-affirming care (GAC) has pushed many to advocate for GAC by pointing to tragic, pathological outcomes of non-treatment, namely suicide. However, these pathologized arguments are a harmful ethical “shortcut” which should be replaced by a meaningful engagement with the ethics of providing GAC to youth.
