- Description: Although many studies have examined the contributions of non-timber forest products (NTFPs) to rural livelihoods, relatively few consider the context in which income shares are shaped. A core one is the local agro-ecological potential because it moulds possible land use options and the potential balance between agricultural and NTFP activities. Using income surveys of 1200 households, this paper examined the absolute and relative contribution of NTFP income at six sites each paired across a gradient of differing agro-ecological potential.

- Description: Sowa, January 3, 1994 (AIA/Caitlin Davies) — Mercy Manakedi Theetso is 29 and has four children. She breast-fed her first child for 18 months, her second for eight months, and she didn’t breast-feed her third child at all. “I was working and the baby stayed with my mother so we used a bottle for the first four months, then we used a cup,” explains Theetso. “Myself, I like to breast-feed but I don’t have the time.” In the 1960s Botswana’s medical practitioners began giving new-born babies the bottle. Now, 30 years later, there is a concerted effort by the Botswana government to promote a return to breast-feeding. But as women have gone out of the home to work, reversing the trend is not an easy task. However, breast-feeding does remain popular in Botswana. “It’s a culturally acceptable norm,” says Virkloti Morewane of UNICEF, and boys and girls are fed for the same amount of time.

- Description: Writing, and the thinking, reading and analytical process that writers engage with to make writing possible, is transformative, and doctoral students in the social sciences especially tend to write themselves into their new identities as ‘doctors’ and recognised researchers. Much has been written in recent years about doctoral writing, including many advice books on how to write a ‘big-book’ or similar doctoral thesis into being. While some of the journal articles and books are helpful, and provide useful accounts of the complex challenges of writing a doctoral thesis, many of the advice books in particular focus more on the text itself, with the writer oddly under-accounted for. Recent research on, for example, doctoral writing groups and doctoral identity speaks into this gap helpfully, but much of it is written in contexts other than South Africa, and much of it is written for rather than by students going through or having recently completed a PhD process. This chapter contributes to a growing body of research and reflection on the role of writing itself in the process of becoming a ‘doctor’. Building on relevant blog posts and critical reflection through a research journal on my own transformative doctoral writing process at a South African university, this chapter will reflect on how challenging yet also potentially thrilling the writing process can be during a PhD. Readers will hopefully find in this chapter useful insights into their own process of becoming a doctor, and ideas for making their own ‘writing and becoming’ process more engaging and rewarding.

“It’s like uprooting trees”: responsive treatment for a case of complex post-traumatic stress disorder following multiple rapes

- Description: This systematic case study documents 27 sessions of assessment and treatment with cognitive therapy of Bongi (23)who presented with major depression, posttraumatic stress disorder and borderline traits. Bongi had been raised in a punitive environment, had been raped three times, the first time at age 9, and had been in a series of abusive relationships. The treatment illustrates the importance of therapist responsiveness in addressing this kind of complex presentation, the importance of drawing on case formulation to guide the course of treatment and the range of different interventions that need to be incorporated into an integrative treatment of a complex case. Self-report measures of depression, anxiety and posttraumatic stress indicators provided evidence that the therapy contributed to positive changes and the qualitative therapy narrative gives details of the nature of some of those changes. Although treatment was not complete when Bongi moved away, Bongi herself judged that the therapy had been a valuable experience which had resulted in her feeling more alive, more confident, and better able to take care of herself.

- Description: In the last 50 years, the human impact on ecosystems has been greater than during any other time period in human history (Millennium Ecosystem Assessment 2003). Large carnivores face anthropogenic threats worldwide, specifically persecution, habitat degradation, and habitat fragmentation (Everatt et al. 2014; Groom et al. 2014; Ripple et al. 2014; Wolfe et al. 2015). Because large carnivores often occupy high trophic levels, their presence influences species at lower levels through trophic cascades (Ripple et al. 2014). Natural experiments, taking advantage of large carnivore management, have shown that large predators provide fundamental ecosystem and economic services that help maintain healthy and diverse ecosystems (Ripple et al. 2014). Additionally, carnivores play an important role in other ecosystem processes, for example, scavenging carnivores may provide regulatory services, such as waste removal, nutrient cycling, and disease regulation. Such services add stability to ecosystems and ensure energy flow through multiple trophic levels (DeVault et al. 2003; Wilson and Wolkovich 2011).

- Description: The manufacturing economy of the Free State reflects both historical dependence on locally available raw materials and high-levels of state intervention, in terms of support for import substitution and Homeland development. In the contemporary era, deindustrialization, the uncertain future of the clothing / textile industries and limited growth over the last ten years, suggests that, in terms of manufacturing, the Free State is a 'lagging' region. While there has been significant expansion in the number of small firms, this is not matched by employment growth and does not compensate for the loss of many large firms and economic downscaling in the Goldfields. Key sectors such as petro-chemicals and gold jewellery present certain opportunities for future growth.

Large pollen loads of a South African asclepiad do not interfere with the foraging behaviour or efficiency of pollinating honey bees

- Description: The pollen of asclepiads (Asclepiadoideae, Apocynaceae) and most orchids (Orchidaceae) are packaged as large aggregations known as pollinaria that are removed as entire units by pollinators. In some instances, individual pollinators may accumulate large loads of these pollinaria. We found that the primary pollinator of Cynanchum ellipticum (Apocynaceae-Asclepiadoideae), the honey bee Apis mellifera, accumulate very large agglomerations of pollinaria on their mouthparts when foraging on this species. We tested whether large pollinarium loads negatively affected the foraging behaviour and foraging efficiency of honey bees by slowing foraging speeds or causing honey bees to visit fewer flowers, and found no evidence to suggest that large pollinarium loads altered foraging behaviour. C. ellipticum displayed consistently high levels of pollination success and pollen transfer efficiency (PTE). This may be a consequence of efficiently loading large numbers of pollinaria onto pollinators even when primary points of attachment on pollinators are already occupied and doing so in a manner that does not impact the foraging behaviour of pollinating insects.

I've come to really dislike the term Born Frees and particularly the way it is used by the media and the politicians. By calling young people Born Frees, society is using apartheid as a reference point to identify a post-apartheid generation. This reference point (the transition to a 'free' society) unfortunately does not resonate with many of the young people that I've encountered in my research and many feel insulted by the implications of this term, which does not apply to them in any way. Should South African society really be using the transition from apartheid to define its young people and how does it relate to the lives of real young people in South Africa today? Are they really Born Free, free from what, free to do what, free individuals or free as a collective? I will look at some of the stereotypes being used in the mainstream media of Born Frees, and then look at the reaction to this term by some real young South Africans.

- Description: The activity of a 0.1% amcinonide cream was compared with those of selected proprietary topical corticosteroid formulations of potencies differing according to the United Kingdom (U.K.) MIMS classification (very potent, potent and moderately potent) using a standard six hour vasoconstrictor assay with multiple reading times. Statistical analysis indicated that 0.1% amcinonide cream feU within the category of a very potent preparation. Three 0.1% amcinonide formulations (cream, combination cream and combination ointment, the last two containing anti-infective agents) were equipotent in the skin-blanching test.

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 58 , Bothus swio is described based on one adult male specimen collected off the coast of Mozambique. Males of this species appear to differ from all known congeners because of their narrow interobital region. Other characters useful for its identification are lack of ocular appendages, relative positions of the anterior margins of the eyes, number of lateral-line scales, length and colour pattern of the ocular-side pectoral fin, lack of orbital spines, dorsal- and anal-fin ray counts, and lack of colour pattern on the blind side. Bothus swio most closely resembles B. pantherinus and B. tricirrhitus.
