- Description: These proverbs from the Yorùbá of southwestern Nigeria and the Bemba of Zambia are a few examples that can be found in many Africa languages. While these proverbs are rich in philosophical sayings and muses, many are being forgotten because fewer and fewer people possess deep knowledge of languages, and in the arts, Africans tend to look to the Global North for theoretical frameworks to examine their art and other cultural properties. The title of this piece is therefore an identification with the potency of the proverbs because of the trends of collaboration that I have noticed in the last few years in African Art Studies. It could also be said to be a call to look into what could be shared within Global Souths in terms of an available knowledge base that could be used to forge ahead rather than subjecting thoughts and knowledge to the Global North.

An experimental test of the allotonic frequency hypothesis to isolate the effects of light pollution on bat prey selection:

- Description: Artificial lights may be altering interactions between bats and moth prey. According to the allotonic frequency hypothesis (AFH), eared moths are generally unavailable as prey for syntonic bats (i.e., bats that use echolocation frequencies between 20 and 50 kHz within the hearing range of eared moths) due to the moths’ ability to detect syntonic bat echolocation. Syntonic bats therefore feed mainly on beetles, flies, true bugs, and non-eared moths. The AFH is expected to be violated around lights where eared moths are susceptible to exploitation by syntonic bats because moths’ evasive strategies become less effective. The hypothesis has been tested to date almost exclusively in areas with permanent lighting, where the effects of lights on bat diets are confounded with other aspects of human habitat alteration. We undertook diet analysis in areas with short-term, localized artificial lighting to isolate the effects of artificial lighting and determine if syntonic and allotonic bats (i.e., bats that use echolocation frequencies outside the hearing range of eared moths) consumed more moths under conditions of artificial lights than in natural darkness.

Chinese engagement of Zimbabwe and the limits of elite agency:

- Description: This article contends that Zimbabwe’s agency in its engagement with China has been limited and at best circumscribed. This owes to factors such as indifference by state authorities to cooperation with civil society actors in negotiating with Chinese actors, the desperation of the The Zimbabwe African National Union – Patriotic Front regime in the face of isolation by erstwhile partners as well as the opacity and secrecy that characterizes significant areas of the Zimbabwe–China relationship. The pressing need for critical institutions such as parliament to play independent oversight roles as well as the creation of space for civil society watchdog functions are highlighted as key enablers if Zimbabwean agency is to generate positive gains from the country’s engagement with China.

- Description: Following on from the African Arts dialogue, “Zimbabwe Mobilizes: ICAC's Shift from Coup de Grăce to Cultural Coup” (Simbao et al. 2017) this dialogue considers another important event in the visual arts that recently took place on the African continent. Like the International Conference on African Cultures (ICAC) that was held in Harare in 2017, this event in Dakar contributes in important ways towards a shift of the center of gravity of the global academy, particularly the study of art history in and of Africa.

Masked in metaphors: counter narratives in the works of Nigerian cartoonist Mike Asukwo

- Description: At the time of independence, most African countries were poised to take charge of their own affairs. However, postcolonial realities characterized by political upheavals, coups and counter-coups, civil wars, and economic downturn, among other setbacks, created a sense of ambivalence in terms of political and economic freedom. In Nigeria, satirical expressions became the tool used against oppressive regimes. In post-independence Nigeria, from the military dictatorial era to the present civilian dispensations,1 sociopolitical issues have been lampooned in different forms of expression such as music, performance, cartoons, and memes. Within this environment, political cartoons began to thrive, as they became a relatively safe way to comment on the political issues of the day (Akande 2002: 2). This was achieved largely by concealing the main subject matter behind the “masks” of metaphoric imagery, which enabled cartoonists to develop narratives that counter the dominant narratives, often opposing governmental policies and practices.

- Description: The quest for novel sources of antibacterial compounds have necessitated the inclusion of ericoid mycorrhizal fungi (ERM) commonly found within the root of ericaceous plants. Agar-well diffusion method was used to detect antibacterial activity and was followed by the microbroth diffusion method [minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)].

- Description: The seasonal activity of adults of eight forensically important blow fly species [Calliphora croceipalpis (Diptera: Calliphoridae), Jaennicke, Lucilia sericata (Meigen) (Diptera: Calliphoridae), L. cuprina (Wiedemann) (Diptera: Calliphoridae), Chrysomya chloropyga (Wiedemann) (Diptera: Calliphoridae), Ch. albiceps (Wiedemann) (Diptera: Calliphoridae), Ch. marginalis (Wiedemann) (Diptera: Calliphoridae), Ch. putoria (Wiedemann) (Diptera: Calliphoridae), Ch. megacephala (Fabricius) (Diptera: Calliphoridae)] was quantified from collections in Makhanda, South Africa. Flies were collected in traps baited with chicken liver and placed in the field at eight locations for four consecutive days each fortnight for 14 mo. The seasonal distribution of each species compared well to published seasonal distributions of these blow flies elsewhere in South Africa, with evidence of year-to-year variation within seasons that might be explained by weather. This information is important for determining when and where certain species are likely to occur and will be of use in forensic investigations and myiasis management plans.

Synthesis of N-Substituted phosphoramidic acid esters as “reverse” fosmidomycin analogues

- Description: An efficient synthetic pathway to a series of novel “reverse” fosmidomycin analogues has been developed, commencing from substituted benzylamines. In these analogues, the fosmidomycin hydroxamate moiety is reversed and the tetrahedral methylene carbon adjacent to the phosphonate moiety is replaced by a nitrogen atom bearing different benzyl groups. The resulting phosphonate esters were designed as potential antimalarial “pro-drugs”.
