We present the confusion-limited 1.28 GHz MeerKAT DEEP2 image covering one \\(\\approx 68'\\) FWHM primary beam area with \\(7.6''\\) FWHM resolution and \\(0.55 \\pm 0.01\\) \\(\\mu\\)Jy/beam rms noise. Its J2000 center position \\(\\alpha=04^h 13^m 26.4^s\\), \\(\\delta=-80^\\circ 00' 00''\\) was selected to minimize artifacts caused by bright sources. We introduce the new 64-element MeerKAT array and describe commissioning observations to measure the primary beam attenuation pattern, estimate telescope pointing errors, and pinpoint \\((u,v)\\) coordinate errors caused by offsets in frequency or time. We constructed a 1.4 GHz differential source count by combining a power-law count fit to the DEEP2 confusion \\(P(D)\\) distribution from \\(0.25\\) to \\(10\\) \\(\\mu\\)Jy with counts of individual DEEP2 sources between \\(10\\) \\(\\mu\\)Jy and \\(2.5\\) mJy. Most sources fainter than \\(S \\sim 100\\) \\(\\mu\\)Jy are distant star-forming galaxies obeying the FIR/radio correlation, and sources stronger than \\(0.25\\) \\(\\mu\\)Jy account for \\(\\sim93\\%\\) of the radio background produced by star-forming galaxies. For the first time, the DEEP2 source count has reached the depth needed to reveal the majority of the star formation history of the universe. A pure luminosity evolution of the 1.4 GHz local luminosity function consistent with the Madau & Dickinson (2014) model for the evolution of star-forming galaxies based on UV and infrared data underpredicts our 1.4 GHz source count in the range \\(-5 \\lesssim \\log[S(\\mathrm{Jy})] \\lesssim -4\\).

New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622-4950 indicate that the magnetar, in a quiescent state since at least early 2015, reactivated between 2017 March 19 and April 5. The radio flux density, while variable, is approximately 100x larger than during its dormant state. The X-ray flux one month after reactivation was at least 800x larger than during quiescence, and has been decaying exponentially on a 111+/-19 day timescale. This high-flux state, together with a radio-derived rotational ephemeris, enabled for the first time the detection of X-ray pulsations for this magnetar. At 5%, the 0.3-6 keV pulsed fraction is comparable to the smallest observed for magnetars. The overall pulsar geometry inferred from polarized radio emission appears to be broadly consistent with that determined 6-8 years earlier. However, rotating vector model fits suggest that we are now seeing radio emission from a different location in the magnetosphere than previously. This indicates a novel way in which radio emission from magnetars can differ from that of ordinary pulsars. The torque on the neutron star is varying rapidly and unsteadily, as is common for magnetars following outburst, having changed by a factor of 7 within six months of reactivation.

This article calls for a fundamental reconstitution of the South African university curriculum through a contrapuntal lens that centres epistemic justice. Drawing on Edward Said’s concepts of worldliness and contrapuntal reading, it argues that dominant knowledge systems must be brought into critical and sustained dialogue with the subjugated epistemologies they have historically excluded. Rather than conceiving the curriculum as a neutral repository of inherited content, the article positions it as a site of ongoing epistemic contestation and structural exclusion. It revisits the Mafeje, Makgoba, and Mamdani affairs as key historical flashpoints that exposed the university’s deep-seated resistance to African and Global South intellectual traditions, often under the guise of safeguarding academic preparedness and institutional standards. The analysis then turns to the post-apartheid shift towards skills-based and managerialist curriculum models. While framed as inclusive and pragmatic, these models have narrowed the curriculum’s scope, sidelining historical critique, ethical reflection, and epistemic diversity in favour of throughput, market readiness, and technical proficiency. In response, the article then explores the marginalised intellectual and cultural contributions of enslaved and indigenous communities at the Cape. Their vernacular literacies, oral traditions, and relational knowledge practices are presented as generative resources for curriculum renewal. The article concludes by proposing five guiding principles: epistemic redistribution, plural reasoning, relational pedagogy, problem-centred learning, and assessment for justice. Together, these offer a framework for reimagining the university as a democratic and socially responsive space of inclusive knowledge making.ContributionThe article advances a contrapuntal curriculum framework that reconstitutes South African university knowledge structures through historical critique and epistemic justice.

Background: Vaping has become an increasingly common mode of administration for both nicotine and cannabis, with overlap among users, devices, as well as nicotine and cannabis companies. There is a need to understand patterns of use among youth, including the way nicotine and cannabis are administered. Methods: Data are from Wave 2 of the ITC Youth Tobacco and Vaping survey, an online survey conducted in 2018 among 16–19 year-olds recruited from commercial panels in Canada (n = 3757), England (n = 3819), and the U.S. (n = 3961). The prevalence of past 30-day vaping nicotine, non-nicotine and cannabis substances, as well as cannabis modes of use was examined. Logistic regression models examined between country differences in prevalence. Results: Past 30-day cannabis use was highest among Canadian youth (16.6%), followed by youth in the U.S. (13.8%) and England (9.0%). Vaping e-cigarettes was substantially more prevalent than vaping cannabis in all three countries. All forms of cannabis use were higher among Canadian and U.S. youth compared to England (p < 0.001 for all). Past 30-day cannabis users in the U.S. were more likely to report vaping cannabis oil (30.1%), and consuming solid concentrates such as wax and shatter (30.2%), compared to cannabis users in Canada (18.6% and 22.9%) and England (14.3% and 11.0%; p < 0.001 for all). Conclusions: Youth are administering cannabis and nicotine using a wide diversity of modes. Cannabis users in the U.S.—where an increasing number of states have legalized medical and non-medical cannabis—reported notably higher use of more potent cannabis products, including cannabis oils and extracts.

This article discusses Research Capacity Development (RCD), in a Faculty of Education at a South African university. It employs the notions of performativity and performance to argue that specific local sites at universities have complex stories to tell about their responsiveness to research output imperatives. The article emphasizes that there is a formative relationship between the specific RCD discursive text of this Faculty and the performance- based activities of its management and academics. The career of RCD in the Faculty is established in the light of specific activities against the background of a small Faculty environment. The article specifically considers the basis for its relative success in the area of doctoral completion by its academic staff and its diminishing article writing output. It draws the conclusion that efforts to secure a vigorous RCD platform depend on the ability to establish a nurturing institutional environment in which a scholarly culture can be encouraged and protected.

The article attempts to show how one person worked out his subjective responsiveness to unfolding events in the contingent fields of politics, popular culture and social justice-orientated activism. Understanding how Muslim discourse is complicit in unjust practices is a crucial motivation for my engagement with Islamic Studies literature.3 My engagement with the literature is based on a 'non-disciplined' reading guided by a commitment to social justice causes. In other words, the legitimacy of a nondisciplined reading lies in the domain of public discourse, taking account of the judgments of social movement peers, popular media interaction, and content circulation via social media and digital technology. In this dialogue a person participates wholly and throughout life: with his eyes, lips, hands, soul, spirit, with his whole body and deeds\".9 Humans engage in dialogue in multiple ways and this dialogical engagement manifests what it means to be human.10 In other words, dialogue is central to what Bakhtin describes as the ethical agent's ideological being and becoming in an open-ended search for authentic human life.

Summary In non-specific abdominal pain, cross-sectional imaging, often valued more than clinical examination in today's technologically advanced age, may reveal a large incidentaloma, posing questions regarding its relation to symptoms and the need for surgical removal. This is a situation that highlights the potential for early detection and treatment yet raises the question as to whether surgery is indeed indicated. This report relates the case of a 79-year-old male, with a longstanding history of abdominal pain, who had a giant loose peritoneal body removed. We discuss the reasons for removal and its pathogenesis.
