The African Continental Free Trade Area (AfCFTA) expands Zimbabwe’s market opportunities, but access does not automatically translate into effective use. This article examines the domestic and regional factors that shape Zimbabwean firms’ ability to convert AfCFTA benefits into higher production, exports, investment, employment, and overall welfare. It draws on a larger mixed-methods study that includes a survey of 62 large firms and small and medium-sized enterprises (SMEs) conducted from May t...

Natural radioactivity in rocks and building materials is a major contributor to outdoor gamma radiation exposure. This study determined the activity concentrations of ²³⁸U (estimated via ²²⁶Ra assuming secular equilibrium), ²³²Th and ⁴⁰K and assessed radiological hazard indices in 30 purposively sampled rocks from Mbeere South, Embu County, Kenya using high-resolution HPGe gamma-ray spectrometry. Mean activity concentrations were 19.02 ± 14.00 Bq？kg...

Background: Acute diffuse hair shedding in women is a diagnostically challenging presentation because telogen effluvium (TE), female pattern hair loss (FPHL), combined TE/FPHL, and diffuse forms of alopecia areata may present with overlapping clinical features. Trichoscopy, histopathology, and immunohistochemistry (IHC) may provide complementary diagnostic information, but their relative contributions in acute diffuse hair shedding remain incompletely characterized, particularly in Africa...

This study aims to investigate the effects of emotional valence and word concreteness on L2 lexical processing among Chinese English learners. A lexical decision task was employed under a 2 (concreteness: concrete vs. abstract) × 3 (emotional valence: positive vs. neutral vs. negative) within-subjects design. Reaction times and accuracy rates were recorded from 50 Chinese non-English major university students. The results reveal that: 1) emotional words (both positive and negative) are processed...

Introduction: In the Democratic Republic of Congo, particularly in remote areas such as the Sankuru health zones, malnutrition in children aged 0 to 5 years is a significant public health issue. It stems from a combination of factors (dietary, health-related, biological, socioeconomic, and environmental). Methods: A cross-sectional analytical study was conducted on 614 children aged 0 to 5 years, from May to October 2025. Multivariate logistic regression facilitated data analysis, leading to the...

In the domain of research on foreign language acquisition, the impact of one’s native language on learning a second language is a critical area of inquiry pursued by numerous academics. While prior studies predominantly examine the negative transfer effects of the native language, the positive aspects of this transfer receive considerably less attention in both local and international contexts. These studies are often narrowly focused on specific linguistic subsystems like lexicon and synt...

This paper reviews how young children’s comprehension develops from an integrated theoretical perspective. Focusing on children aged three to six, it defines comprehension primarily as oral-language and narrative meaning-making, while recognising contributions from visual, social, and experiential cues. The review examines five complementary perspectives: Piagetian constructivism, language-acquisition theory, sociocultural theory, schema theory, and information-processing theory. Construct...

Artificial intelligence (AI) is reshaping how firms sense, interpret, and act upon financial information, yet the mechanisms through which AI adoption translates into superior corporate financial decision-making remain theoretically under-specified and empirically contested. Drawing on the resource-based view, dynamic capability theory, and organizational information processing theory, this study advances and tests an integrated model in which financial analytics capability and organizational ag...

The chemical profiles of methanolic extract from the leaves, trunk, and roots of Nauclea diderrichii were determined by liquid chromatography coupled with mass spectrometry (LC-MS). Total polyphenol content was determined using the Folin-Ciocalteu reagent method, and total flavonoid content using the aluminum trichloride method. Antioxidant potential was evaluated via DPPH free radical scavenging, ferric reducing antioxidant power (FRAP), and HPTLC bioautography. Extraction yields were hi...

With social development, economic trade and cultural exchanges between China and other countries have become more frequent. In this context, to enhance the competitiveness of domestic industries and cultural influence, it is necessary to base international communication on a sound understanding of the differences between Chinese and Western cultures and to carry out corresponding communication and promotional work with care. Notably, the umbrella term “Western tea culture” covers hig...
