- Description: It is an honour and a pleasure to report on the activities of the Academy of Pharmaceutical Sciences since the PSSA AGM in 2016. The Academy of Pharmaceutical Sciences of the Pharmaceutical Society of South Africa (APSSA) held their 37th Annual Conference and 38th Annual General Meeting at the All African Congress on Pharmacology and Pharmacy. The conference was jointly organised by the Academy of Pharmaceutical Sciences of South Africa (APSSA), the South African Society for Basic and Clinical Pharmacology (SASBCP) on behalf of Pharmacology for Africa (Pharfa) and the Toxicology Society of South Africa (ToxSA). The annual APSSA conference was hosted by the Department of Pharmaceutical Sciences, Tshwane University of Technology under the leadership of Dr Ilze Vermaak and was held from 5-8 October 2016 at Misty Hills Conference Centre, situated close to the Cradle of Humankind.

- Description: The feature level, unlike the match score level, lacks multi-modal fusion guidelines. This work demonstrates a new approach for improved image-based biometric feature-fusion. The approach extracts and combines the face, fingerprint and palmprint at the feature level for improved human identification accuracy. Feature-fusion guidelines, proposed in our recent work, are extended by adding a new face segmentation method and the support vector machine classifier. The new face segmentation method improves the face identification equal error rate (EER) by 10%. The support vector machine classifier combined with the new feature selection approach, proposed in our recent work, outperforms other classifiers when using a single training sample. Feature-fusion guidelines take the form of strengths and weaknesses as observed in the applied feature processing modules during preliminary experiments. The guidelines are used to implement an effective biometric fusion system at the feature level, using a novel feature-fusion methodology, reducing the EER of two groups of three datasets namely: SDUMLA face, SDUMLA fingerprint and IITD palmprint; MUCT Face, MCYT Fingerprint and CASIA Palmprint.

- Description: South African government has been promulgating pieces of legislation aimed at ensuring racial integration, especially in higher education, and indirectly enforcing acculturation in historically white universities. Studies have proven that institutional cultures in historically white universities alienate and exclude black students' identities. These students' sense of social identity, which includes culture, heritage, language and traditions, and consequently self-esteem and self-concept, is altered in these institutions. Research has been scant regarding the shape and form that black students' identity assumes when they get to these spaces. Using Tajfel and Turner's (1979) social identity theory and Berry's (2005) theory of acculturation, this article explores the experiences of black students in negotiating their social identities in historically white universities. Evoking Steve Biko's analysis of 'artificial integration' (1986), we hope to illustrate how the 'integration'.

The contradictory conceptions of research in historically black universities

- Description: Research is conceptualised in multiple and contradictory ways within and across Historically Black Universities (HBUs) with consequences for knowledge production. Under the apartheid regime, research was deliberately underdeveloped in such institutions and this continues to have an impact. We argue that if HBUs are to move from the constraints of the past into the possibilities of the future, there is a need for a thorough understanding both of how research is currently conceptualised, and of the consequences of such conceptions for research output. We used a critical discourse analysis of interviews, documents and survey data from seven HBUs to identify the dominant discourses about the purposes of research. The findings are four dominant conceptions of research that sometimes contradict each other across and within the HBUs. These are research as integral to academic identity; research for social justice; research as an economic driver and research as an instrumentalist requirement for job security, promotion and incentives. These conceptions seemed to emerge in part because of the history of the institutions and create both constraining and enabling effects on research production.

- Description: African tulip tree, Spathodea campanulata Beauv. (Bignoniaceae), is a large tree of secondary forests, forest edges and savannas that is indigenous to Central and West Africa (Bidgood 1994). It has been widely utilised as an ornamental plant due to its beautiful flowers, fast growth and relative ease of cultivation, as a shade tree in parks and coffee plantations, and as a living fencepost (Francis 1990). Naturalisation has often followed cultivation of the plant, which is now established outside of the native range in Africa (Hedberg et al. 2006), the Caribbean (Francis 1990; Labrada and Medina 2009) and many Pacific islands (Meyer 2004), including Hawaii, Papua New Guinea, Fiji, Samoa, Tonga,Vanuatu and Tahiti (Lowe et al. 2000; Dovey et al. 2004; Labrada and Medina 2009). On some of these islands it has become a destructive weed, invading indigenous forests and having a severe impact on agricultural production (Labrada and Medina 2009; Larrue et al. 2014). This has resulted in African tulip tree being recognised as one of the 100 worst alien invasive species worldwide, along with only 30 other terrestrial plants (Lowe et al. 2000).
