Use of the nested polymerase chain reaction for detection of Toxoplasma gondii in slaughterhouse workers in Thika District, Kenya

Background. The widely used methods of diagnosis of Toxoplasma gondii are serological. Current reports indicate a high seroprevalence of T. gondii in humans in Kenya. There is a need for more sensitive diagnostic tests, especially when the specific antibody titres are below detectable threshold levels. Use of the polymerase chain reaction (PCR) targeting the repetitive 529 base pair loci has been reported to be sensitive and specific.Objective. To detect T. gondii in a high-risk group of public health workers in Thika District, Kenya.Methods. In total, 87 human blood samples were collected from male slaughterhouse workers between 1 March 2013 and 25 June 2013. The DNA extracted was amplified by the nested PCR.Results. T. gondii was detected in 39.1% (34/87) of the workers. In the cow-sheep-goat slaughterhouses the prevalence ranged between 20% and 60%, while all the chicken slaughterhouse workers (6/6, 100%) tested positive. The difference in T. gondii positivity between the workers in the chicken slaughterhouse and those in the cattle-sheep-goat slaughterhouses was statistically significant (p=0.003).Conclusion. This study shows the presence of T. gondii in an asymptomatic high-risk group in Thika District, indicating the need for enhancement of public health awareness

Nonhuman humanitarianism: when ‘AI for good’ can be harmful

Artificial intelligence (AI) applications have been introduced in humanitarian operations in order to help with the significant challenges the sector is facing. This article focuses on chatbots which have been proposed as an efficient method to improve communication with, and accountability to affected communities. Chatbots, together with other humanitarian AI applications such as biometrics, satellite imaging, predictive modelling and data visualisations, are often understood as part of the wider phenomenon of ‘AI for social good’. The article develops a decolonial critique of humanitarianism and critical algorithm studies which focuses on the power asymmetries underpinning both humanitarianism and AI. The article asks whether chatbots, as exemplars of ‘AI for good’, reproduce inequalities in the global context. Drawing on a mixed methods study that includes interviews with seven groups of stakeholders, the analysis observes that humanitarian chatbots do not fulfil claims such as ‘intelligence’. Yet AI applications still have powerful consequences. Apart from the risks associated with misinformation and data safeguarding, chatbots reduce communication to its barest instrumental forms which creates disconnects between affected communities and aid agencies. This disconnect is compounded by the extraction of value from data and experimentation with untested technologies. By reflecting the values of their designers and by asserting Eurocentric values in their programmed interactions, chatbots reproduce the coloniality of power. The article concludes that ‘AI for good’ is an ‘enchantment of technology’ that reworks the colonial legacies of humanitarianism whilst also occluding the power dynamics at play

Education for Sustainable Development and retention: unravelling a research agenda

This paper considers the question of what education for sustainable development (ESD) research might signify when linked to the concept of “retention”, and how this relation (ESD and retention) might be researched. It considers two different perspectives on retention, as revealed through educational research trajectories, drawing on existing research and case studies. Firstly, it discusses an ESD research agenda that documents retention by focusing on the issue of keeping children in schools. This research agenda is typical of the existing discourses surrounding Education for All (EFA). It then discusses a related ESD research agenda that focuses more on the pedagogical and curricular aspects of retention, as this provides for a deeper understanding of how ESD can contribute to improving the quality of teaching and learning within a wider EFA retention agenda

Bye-bye Barack: dislocating afropolitanism, spectral marxism and dialectical disillusionment in two Obama-era novels

In contextually specific and formally distinctive ways, Chimamanda Ngozi Adichie’s Americanah and Imbolo Mbue’s Behold the Dreamers are fictional interrogations of Obama’s presidential pledge to resuscitate the American dream on the wake of the global financial crash. This paper explores how they supplement and challenge familiar tropes associated with African and American, rather than African-American, diaspora writing. Given broader debates within transnational literary studies about flows and exchanges (of people, finance, cultural production, dissemination, consumption et al.) linking the global South and North, I consider how these texts grapple with the complexities and complicities of contemporary neoliberalism through the lens of renascent African Marxisms. While my chosen writers could not be described as Marxist, I engage with more materially oriented scholarship, such as Krishnan’s Writing Spatiality in West Africa and Ngugi’s The Rise of the African Novel, to consider how Americanah and Behold the Dreamers circulate in a global literary marketplace where certain texts, not to mention authors, are seen as symptomatic of an African and/or Afropolitan and/or ‘Africapitalist’ renaissance. By grappling with Marxist-inflected scholarship, this paper interrogates the politics, as well as poetics, of the oft-conspicuous airbrushing of those socio-economic, specifically class concerns at the heart of these entangled debates

Open educational resources: Education for the world?

Education is widely seen as an important means of addressing both national and international problems, such as political or religious extremism, poverty, and hunger. However, if developing countries are to become societies that can compete properly with Western industrialized countries, not only is a fundamental shift in thinking with regard to the value of education and more/better provision of teaching required, but strong support from other countries is needed as well. This article explores questions such as whether Western policymakers can avoid a repetition of some of the failures of the past few decades in terms of providing foreign aid; how educators and providers of educational scenarios and learning contents can foster and manage the creation of a worldwide knowledge society; and in particular, if the provision of open educational resources (OER) can realistically overcome the educational gap and foster educational justice

Post-imperialism, postcolonialism and beyond: towards a periodisation of cultural discourse about colonial legacies

Taking German history and culture as a starting point, this essay suggests a historical approach to reconceptualising different forms of literary engagement with colonial discourse, colonial legacies and (post-) colonial memory in the context of Comparative Postcolonial Studies. The deliberate blending of a historical, a conceptual and a political understanding of the ‘postcolonial’ in postcolonial scholarship raises problems of periodisation and historical terminology when, for example, anti-colonial discourse from the colonial period or colonialist discourse in Weimar Germany are labelled ‘postcolonial’. The colonial revisionism of Germany’s interwar period is more usefully classed as post-imperial, as are particular strands of retrospective engagement with colonial history and legacy in British, French and other European literatures and cultures after 1945. At the same time, some recent developments in Francophone, Anglophone and German literature, e.g. Afropolitan writing, move beyond defining features of postcolonial discourse and raise the question of the post-postcolonial

From Feminist Anarchy to Decolonization: Understanding abortion health activism before and after the Repeal of the 8th Amendment

This article analyses abortion health activism (AHA) in the Irish context. AHA is a form of activism focused on enabling abortion access where it is restricted. Historically, AHA has involved facilitating the movement of abortion seekers along ‘abortion trails’ (Rossiter, 2009). Organisations operate transnationally, enabling access to abortion care across borders. Such AHA is a form of feminist anarchism, resisting prohibitions on abortion through direct action. However, AHA work has changed over time. Existing scholarship relates this to advancements in medical technology, particularly the emergence of telemedicine and the increased use of early medical abortion. This article goes beyond those explanations to explore how else AHA has changed by comparing the work of AHA before and after the Republic of Ireland’s referendum on abortion in May 2018. Based on this, I argue that there is a visible shift in the politics of AHA. Drawing on qualitative data from research on AHA organisations along the Liverpool–Ireland Abortion Corridor, specifically those based outside Ireland, the article argues that in the aftermath of the referendum, Irish AHA has increasingly moved towards decolonising feminist activism, thus drawing attention to the relationship between abortion health activists (AHAs) and broader political discourses entangled with abortion law reform
