- Description: Publisher version , Introduction: The River goby, Glossogobius callidus (Smith 1937), occurs naturally in rivers and the upper reaches of estuaries along the eastern seaboard of southern Africa (Whitfield, 1998; James et al., 2007; Wasserman, Strydom & Wooldridge, 2010). This fish species is among the most abundant of fishes in many river systems of the region and is considered an important predator in these habitats, feeding on invertebrates and small fish (Whitfield, 1998; Strydom & Neira, 2006; Wasserman, 2012; Wasserman et al., 2014). Despite this, ecological information on this goby is sparse and to date, no published records on the biology of the species exist. The urgent need for such information was recently highlighted in a study that identified G. callidus as a potentially invasive species, given its ability to rapidly establish in novel environments (Woodford et al., 2013). The present study therefore endeavoured to determine the reproductive guild to which G. callidus belong and describe aspects of their spawning. This was performed by closely observing wild caught, mature G. callidus in aquaria over a 25-day period.

- Description: publisher version , It’s said that behind every powerful language is an army and money. Consider the case of English. In South Africa, as in its other colonies, the British arrived with the Bible in one hand and the breech-loader in the other. Behind them was the English language, military might and money. British missionaries wanted to convert Africa’s indigenous “heathens” to Christianity; to clone little English people on the continent through the medium of English. Next came the Afrikaners, descended from the Dutch. Their slaves created a “kitchen” language out of Dutch and called it Afrikaans. White Afrikaners appropriated it as their own and it became the language of apartheid. One of the tipping points of white rule was the 1976 Soweto uprising – a furious, powerful response to the news that Afrikaans would become a compulsory medium of instruction. Now there is a new potential coloniser on South Africa’s linguistic block. From 2016, Mandarin will be taught in the country’s schools as a Second Additional Language. This new government policy will see African languages bumped even further down the educational pecking order.

It traces the judiciary’s stance on the separation of powers in the different stages of the litigation - before, during and after the conclusion of the legislative process. It does so against the background of South African precedent on the doctrine and in the light of a perceived power imbalance between the branches of government. Ultimately, it questions the appropriateness of the current understanding of the doctrine of separation of powers in the context of a dominant-party democracy.

- Description: Publisher version , Although most knowledge on the biology of Sousa plumbea has primarily come from South African waters, a number of research gaps remain on the natural history and status of the species in the region. Research on two populations in South African waters for which some historical data exist may aid in highlighting long-term changes in the biology and natural history of this little known coastal delphinid. Recent studies on the age, growth and reproduction of animals incidentally caught in shark nets in Richards Bay, KwaZulu-Natal, yielded a lower maximum age estimate of 24 (previously 46) growth-layer-groups (GLGs), sexual maturity of 7.5 and 8 GLGs in males and females (previously 12–13 and 10 GLGs, respectively), an ovulation rate of 0.2 and a 5-year calving interval (previously 0.3 and 3-year calving interval) than previously reported. These differences may be due to a difference in the interpretation of GLGs between observers or a predominance of young males being caught in the shark nets. Stomach content analysis revealed a change in the relative proportions of the main prey items over the past 25 years, but no difference in species richness or diversity was found between the sexes. No change in trophic level was recorded between 1972 and 2009. Field studies in Algoa Bay, Eastern Cape, conducted 16 years apart indicated a decline in the mean group size (from 7 to 3 animals), a decline in the maximum group size (from 24 to 13 animals), an increase in solitary individuals (15.4–36%), and a change in behaviour from predominantly foraging (64–18%) to mainly travelling (24–49%). The observed changes are suggestive of a change in food availability, resulting in a range shift or a potential decline in numbers. These studies indicate the importance of long-term studies to monitor population changes and their possible causes. A number of threats, such as shark nets, pollution (noise and chemical), and coastal development and disturbance, to the humpback dolphin populations in South Africa have been identified. Urgent action is required to ensure continued existence of the species in South African waters.

- Description: publisher version , International scholars who rely on the Personal Wellbeing Index (PWI) to compare cross-cultural quality of life have often been confronted with the problems of nuances getting ‘lost in translation’. This qualitative study explored the meaning of the isiXhosa version of the PWI in focus group discussions with native speakers. Participants in the study discussed how they understood and rated their lives on each item in the index. The discourse conveyed the different shades of meaning associated with the PWI items of life satisfaction and eight domains of life. The study found that PWI items related to material well-being, living standards, achievements in life and future (financial) security were best understood. The PWI items referring to personal relationships and community connectedness were seen as nearly identical in meaning. Both translation and cultural factors may be responsible for the conflation of these two items. Noteworthy is that the PWI item on religion and spirituality was seen to embrace both Christian and traditional African beliefs and practice, without prejudice. A new item on daily activities was piloted with good results. The focus group study also showcased the manner in which discussants worked with the rating scale and drew on social comparisons when evaluating global and domain satisfactions. It is concluded that cognitive testing of PWI items in different translations will serve not only to appraise the validity of PWI ratings across cultures, but importantly also opens a window on what makes for a life of quality in a particular social setting.

- Description: publisher version , In recent years there have been calls both for building the knowledge base of academic development (AD) and for systematic induction of newcomers to the field if AD is to advance as a professional and an academic field. Despite the importance and complexity of AD, induction of novice academic developers remains mostly informal and predominantly focuses on the practices of the field. We argue that more-experienced academic developers have an obligation to provide formal and systematic routes into the field and its knowledge base than is currently the case. One way of doing this is through offering a formal course for growing the next generation of academic developers. Such a course could equip newcomers with a more solid and shared knowledge base, thus contributing to shaping the epistemic spine of AD. In this paper, using Maton's Legitimation Code Theory, we offer an analysis of an existing course aimed at equipping novices with the theoretical and practical knowledge to enable them to solve some of the problems in higher education. From this analysis have emerged general principles that could inform the selection, sequencing and pacing of knowledge in a formal course for academic developers.

- Description: The Recognition of Customary Marriages Act 1998 (the Act) regulates all matters in relation to customary marriages in South Africa. The Act was specifically enacted to recognize customary marriages as valid, but was also passed to address gender inequality by regulating various customary marriage aspects, the most important being registration and proprietary consequences. This article reflects on the findings of a qualitative study on the registration and proprietary consequences of customary marriages conducted in two rural sites in the Eastern Cape (the former Ciskei and Transkei) and one urban site in the Western Cape (Khayelitsha). These findings show two important issues. First, that access to resources upon death of a spouse or divorce is often premised on successful registration of the marriage, which seldom occurs. Secondly, that the continued patriarchal nature of customary marriages stands in the way of realizing gender equality, particularly in relation to the proprietary consequences of a marriage. As a result, we make possible recommendations of how the Act’s objectives can be met.

- Description: Publisher version , Temporal changes in fatty acid composition and δ15N, δ13C stable isotope values of the phytobenthos growing on artificial clay substrates under natural conditions over a 28-day period at an upstream and a downstream site in the Kowie River near Grahamstown were investigated in 2012. High concentrations of diatom markers 16:1ω7 and 20:5ω3 fatty acids were recorded, especially at the downstream site, reflecting the importance of diatoms in contributing to the phytobenthos communities at that station. After day 7 at the downstream site the average δ15N value of the phytobenthos was lighter, gradually increasing by ∼2‰ and ∼5‰ overall to heavier values on day 28. At the upstream site there were no significant changes (<1‰ increase) in δ15N values of the phytobenthos over time. Stable nitrogen (δ15N) and carbon (δ13C) signatures in the phytobenthos communities were significantly different between sites (one-way ANOVA; p < 0.001). The stable isotope values and fatty acid concentrations of phytobenthos at the downstream site were different to those of the phytobenthos at the upstream site, and they changed concurrently with changes in the phytobenthos community structure. At the downstream site there was a strong correlation of the δ15N of phytobenthos with nitrates (R = 0.56) and time (weeks; R = 0.81). However, the fatty acids were not specific enough to characterise the composition of phytobenthos communities. Other biomarker methods, such as stable isotopes and microscopic examination of the communities, were found to be useful. The results from this relatively small-scale tile experiment indicate the complexity of changes in fatty acid composition and δ15N, δ13C stable isotope values of a phytobenthos community. Stable isotope and fatty acid composition can be successfully used to map changes in phytobenthos composition and carbon and nitrogen flow patterns along a river continuum.

- Description: Publisher version , Temporal changes in fatty acid composition and δ15N, δ13C stable isotope values of the phytobenthos growing on artificial clay substrates under natural conditions over a 28-day period at an upstream and a downstream site in the Kowie River near Grahamstown were investigated in 2012. High concentrations of diatom markers 16:1ω7 and 20:5ω3 fatty acids were recorded, especially at the downstream site, reflecting the importance of diatoms in contributing to the phytobenthos communities at that station. After day 7 at the downstream site the average δ15N value of the phytobenthos was lighter, gradually increasing by ∼2‰ and ∼5‰ overall to heavier values on day 28. At the upstream site there were no significant changes (<1‰ increase) in δ15N values of the phytobenthos over time. Stable nitrogen (δ15N) and carbon (δ13C) signatures in the phytobenthos communities were significantly different between sites (one-way ANOVA; p < 0.001). The stable isotope values and fatty acid concentrations of phytobenthos at the downstream site were different to those of the phytobenthos at the upstream site, and they changed concurrently with changes in the phytobenthos community structure. At the downstream site there was a strong correlation of the δ15N of phytobenthos with nitrates (R = 0.56) and time (weeks; R = 0.81).

- Description: This article considers whether public servants should be exempt from South Africa’s equality provisions and anti-discrimination legislation in solemnizing same-sex marriages. In order to deal with this question, the article analyses the treatment of freedom of conscience and conscientious objection by comparing the solemnization of same-sex marriage by public servants, with another public service: that of terminations of pregnancy. While each situation will inevitably turn on the particular circumstances of the case, I argue that there should be a content-neutral guiding principle (as well as consistency) in dealing with these situations. The issue in each situation is narrowed to whether a civil servant’s personal convictions can override the state’s secular obligations in providing a service, and whether there is room for a qualified right to conscientious objection. By analysing the matter in this way, it is clear that the unqualified statutory exemption clause in South Africa’s Civil Union Act is constitutionally objectionable.

- Description: Publisher version , Sensitivity to chemical cues associated with predation threat has been well observed in many freshwater zooplankters, yet few studies have highlighted such sensitivity in eury- and stenohaline metazoans. We aimed to assess sensitivity to conspecific chemical alarm cues in the estuarine copepod, Paracartia longipatella. Alarm cues associated with predation have been shown to have population level effects on certain zooplanktonic species. As such, we assessed the occurrence of such effects on population dynamics of P.longipatella over a 12 day period. Using experimental in situ mesocosms, we compared P.longipatella adult, copepodite and nauplii numbers between three treatments; one inoculated with conspecific alarm cues, one containing direct predation pressure (zooplanktivorous fish), and a control treatment containing no predation threat. Trends in population abundances were similar between the direct predation and alarm cue treatments for the six days of the experiment, decreasing in abundance. During the latter half of the study, however, P.longipatella abundances in the alarm cue treatment increased, while those in the presence of direct predation continued to decrease. In the treatment absent of any predation threat, P.longipatella abundances increased consistently over time for the duration of the study. We suggest that P.longipatella are indeed sensitive to conspecific alarm cues associated with predation threat. Furthermore, we propose that prolonged exposure to conspecific alarm cues in the absence of any real threat results in a reduction in sensitive to these cues.

- Description: Publisher version , This paper examines dependence on environmental resources and impacts on household welfare among the indigenous San and Mier rural communities neighbouring Kgalagadi Transfrontier Park in South Africa. Data on the various household income types, including environmental income, were collected through a structured survey of 200 households. Environmental income constituted 20% of the total income. The poorest income quintile showed the highest relative dependence on environmental income (31%), though absolute environmental income increased with total income. Poverty analyses showed that poverty incidence and poverty gap would increase by 13 and 7 percentage points respectively without environmental income. Gini-coefficient analyses revealed that income inequality would increase by 6 percentage points for all households if environmental income was excluded. The results generally suggest that environmental income is important for both the poor and the well-off, and wealth accumulation might be tied to resource use. There is a case for promoting sound environmental management, and sustainable and fair resource use in the Kalahari drylands in order to help pull more households out of poverty. Our findings also point to issues of heterogeneity in resource access even among indigenous communities previously thought to be homogenous. These should be key considerations for conservation interventions.

- Description: Publisher version , A common global perception of group work in the higher education context is that it has the potential to act as a platform which can enable student learning by means of interactions, shared diverse experiences, deep engagement with subject concepts and the achievement of tasks collaboratively. Indeed, in different socio-economic, historical and institutional contexts, group work activities have become levers by which deeper learning could be achieved. Drawing on perceptions and experiences of group work among environmental science students at a South African university, we investigate the ways in which group work could be more expansively viewed as 'terrains of learning' for students. The results in general indicate that students have positive perceptions and experiences of group work, though problematic elements are evident. This particular case study points to the attention that should be paid to understanding issues of background, ethnicity and various student personalities which could hinder or enable the desired student learning. Such an understanding could contribute to debates regarding the achievement of higher quality learning, given issues of diversity and transformation in the South African higher education context.

In contrast, domain-specific national pride is characterized as 'not overtly nationalistic, imperialistic, nor chauvinistic' and is expressed as positive feelings towards national accomplishments in a range of domains including arts, science and sport. Most scholars who take an interest in the impact of sport mega-events acknowledge that national pride is related to concepts such as patriotism and nationalism whose meanings are difficult to disentangle. The South African Social Attitudes Survey (SASAS), which has tracked the attitudes of South African adults around the 2010 World Cup, has confirmed this idea. The longitudinal SASAS study found that subsequent to the event, there was an enormous upswing in the belief that the World Cup had a positive impact on social cohesion.

- Description: Publisher version , Although predation has been identified as an important community driver, the role of predator diversity in structuring estuarine zooplankton has not been assessed. As such, we investigated the effects of two different zooplanktivorous fish species on the estuarine zooplankton community during a 12-day mesocosm study. Three experimental treatments were established, whereby natural zooplankton communities were subject to either (1) no predatory pressure, (2) predation by a pelagic predator (Monodactylus falciformis) or (3) predation by a hyper-benthic predator (Glossogobius callidus). The pelagic feeding M. falciformis fed largely on the numerically dominant mid-water copepod species, Paracartia longipatella. In contrast, the hyper-benthic fish had a greater predatory impact on the less numerically dominant copepod, Pseudodiaptomus hessei, which demonstrates strong diel vertical migration. Variations in prey-population regulation are ascribed to the distinct behavioural differences of the predators, and mediated by the differences in behaviour of the copepod species.

- Description: publisher version , There is no defined route to becoming an academic developer. The research on pathways into the field (e.g. Kensington-Miller, Brailsford, and Gossman, 2012; McDonald, 2010; McDonald and Stockley, 2008) shows that in most cases ‘serendipity and chance played a role’ (McDonald, 2010, p. 40). Moreover, induction into academic development (AD) is often ad hoc, haphazard, and informal. Due to the changing higher education (HE) context, the field has grown exponentially and in many countries now plays a central role in institutions. This has generated increased demand for knowledgeable and competent developers that are able to contribute towards solving some vexing problems in contemporary HE. Current recruitment and induction processes of new developers do not necessarily meet this demand. In light of the above, we pose the question: given the changing context of HE and the field of AD, is it not time for us to induct newcomers into the field more systematically? As Kensington-Miller et al. (2012) suggest, we should not leave the induction of the next generation of developers to chance. We suggest that one way of ensuring appropriate induction is through a formal course for developers. Difficulties for newcomers to the field are illustrated by Kensington-Miller et al. (2012) when they report seeking ‘top tips’ at a HERDSA conference. We do not dismiss informal learning at conferences or the role of mentoring, coaching, apprenticeship, and so on, in inducting developers, nor do we minimise the benefits of relatively structured processes such as fellowship programmes, workshops, and postgraduate qualifications in related fields. However, these ways of induction may not offer novices the structured and systematic developmental opportunities needed to become developers able to fulfil varied, complex, and sometimes contradictory roles.

- Description: Publisher version , We apply John R. Commons’s negotiational psychology, specifically his principle of sovereignty, to the development of a discordant regulatory culture and its likely impact on the economic potential of recreational fishing. Using South African environmental judicial precedents and other documentation, we formulate six plausible hypotheses. We argue that regulatory incoherence, entitlement insecurity, corporate-dominated social valuation, strategic power coalitions, lack of procedural fairness, and the extent of judicial enforcement of environmental rights help explain the economic potential and isolation of the freshwater recreational fisheries sector. We find a consistent pattern of extraction and monopolization of sovereign power by the Department of Mineral Resources from propertied parties. Thus, regulatory domination is a major mechanism affecting the economic potential of recreational fisheries in the Trout Triangle. While Commons postulated that private property is a sufficient condition for participation in the determination and use of sovereign power, we argue that private/public property is only a necessary condition. The conjunctive sufficient condition is the existence of both regulatory coherence between spheres of government and property.
