- Description: Ocean warming ‘hotspots’ are regions characterized by above-average temperature increases over recent years, for which there are significant consequences for both living marine resources and the societies that depend on them. As such, they represent early warning systems for understanding the impacts of marine climate change, and test-beds for developing adaptation options for coping with those impacts. Here, we examine five hotspots off the coasts of eastern Australia, South Africa, Madagascar, India and Brazil. These particular hotspots have underpinned a large international partnership that is working towards improving community adaptation by characterizing, assessing and projecting the likely future of coastal-marine food resources through the provision and sharing of knowledge. To inform this effort, we employ a high-resolution global ocean model forced by Representative Concentration Pathway 8.5 and simulated to year 2099. In addition to the sea surface temperature, we analyse projected stratification, nutrient supply, primary production, anthropogenic CO2-driven ocean acidification, deoxygenation and ocean circulation. Our simulation finds that the temperature-defined hotspots studied here will continue to experience warming but, with the exception of eastern Australia, may not remain the fastest warming ocean areas over the next century as the strongest warming is projected to occur in the subpolar and polar areas of the Northern Hemisphere. Additionally, we find that recent rapid change in SST is not necessarily an indicator that these areas are also hotspots of the other climatic stressors examined. However, a consistent facet of the hotspots studied here is that they are all strongly influenced by ocean circulation, which has already shown changes in the recent past and is projected to undergo further strong change into the future. In addition to the fast warming, change in local ocean circulation represents a distinct feature of present and future climate change impacting marine ecosystems in these areas.

- Description: This article seeks to understand what South African universities are doing by making use of language as a tool or as an enabling voice towards Africanisation and transformation with particular reference to Rhodes University, which serves as a case study. Although many universities now have language policies in place and are part of an enabling policy environment, when it comes to using language as part of transformation and asserting an African voice, there are still policy implementation challenges. It is argued in this article that implementation of policy, including university language policies, is now a key indicator for two levels of transformation; namely the more superficially visible or visual representation transformation, as well as deeper curriculum transformation through appropriate language usage. It is the latter form of transformation that largely eludes the contemporary South African university, whether these are historically black universities (HBUs) or historically white universities (HWUs). With the exception of a few best practices that are highlighted in this article, it is argued that transformation of the curriculum remains a long-term process, in the same way that language policy implementation is an ongoing process and requires commitment at all levels of university managerial and academic culture. The African voice in higher education remains an elusive one; though it is gaining ground, as evidenced by the recent removal of the Cecil John Rhodes Statue at the University of Cape Town. Furthermore, there is evidence of selected ongoing curriculum and pedagogic transformation, as presented in this article.

- Description: The ever-widening scope and range of global change and interconnected systemic risks arising from people–environment relationships (social‐ecological risks) appears to be increasing concern among, and involvement of, citizens in an increasingly diversified number of citizen science projects responding to these risks. We examined the relationship between epistemic cultures in citizen science projects and learning potential related to matters of concern. We then developed a typology of purposes and a citizen science epistemic‐cultures heuristic and mapped 56 projects in southern Africa using this framework. The purpose typology represents the range of knowledge‐production purposes, ranging from laboratory science to social learning, whereas the epistemic‐cultures typology is a relational representation of scientist and citizen participation and their approach to knowledge production. Results showed an iterative relationship between matters of fact and matters of concern across the projects; the nexus of citizens’ engagement in knowledge‐production activities varied. The knowledge‐production purposes informed and shaped the epistemic cultures of all the sampled citizen science projects, which in turn influenced the potential for learning within each project. Through a historical review of 3 phases in a long‐term river health‐monitoring project, we found that it is possible to evolve the learning curve of citizen science projects. This evolution involved the development of scientific water monitoring tools, the parallel development of pedagogic practices supporting monitoring activities, and situated engagement around matters of concern within social activism leading to learning‐led change. We conclude that such evolutionary processes serve to increase potential for learning and are necessary if citizen science is to contribute to wider restructuring of the epistemic culture of science under conditions of expanding social-ecological risk.

Modelling transport of inshore and deep-spawned chokka squid (Loligo reynaudi) paralarvae off South Africa: the potential contribution of deep spawning to recruitment

- Description: The South African chokka squid, Loligo reynaudi, spawns both inshore (≤70 m) and on the mid-shelf (71–130 m) of the Eastern Agulhas Bank. The fate of these deep-spawned hatchlings and their potential contribution to recruitment is as yet unknown. Lagrangian ROMS-IBM (Regional Ocean Modelling System-Individual-Based Model) simulations confirm westward transport of inshore and deep-spawned hatchlings, but also indicate that the potential exists for paralarvae hatched on the Eastern Agulhas Bank deep spawning grounds to be removed from the shelf ecosystem. Using a ROMS-IBM, this study determined the transport and recruitment success of deepspawned hatchlings relative to inshore-hatched paralarvae. A total of 12 release sites were incorporated into the model, six inshore and six deep-spawning sites. Paralarval survival was estimated based on timely transport to nursery grounds, adequate retention within the nursery grounds and retention on the Agulhas Bank shelf. Paralarval transport and survival were dependent on both spawning location and time of hatching. Results suggest the importance of the south coast as a nursery area for inshore-hatched paralarvae, and similarly the cold ridge nursery grounds for deep-hatched paralarvae. Possible relationships between periods of highest recruitment success and spawning peaks were identified for both spawning habitats. Based on the likely autumn increase in deep spawning off the Tsitsikamma coast, and the beneficial currents during this period (as indicated by the model results) it can be concluded that deep spawning may at times contribute significantly to recruitment.

- Description: Publisher version , Ecologists are interested in the factors that control, and the variability in, the contributions of different sources to mixed organic materials travelling through lotic systems. We hypothesized that the source matter fuelling mixed organic pools in a river–estuary continuum varies over space and time. Samples of the mixed organic pools were collected along a small temperate river (Kowie River) in southern Africa during early and late spring, summer and winter. The C:N ratios of suspended particulate matter (SPM) collected during summer and winter indicated that the lower reaches of the system had similar organic matter contributions. Stable isotope analysis in R revealed that aquatic macrophytes were significant contributors to SPM in the upper reaches. Bulk detritus had large allochthonous matter components in the lower reaches, and contributions of aquatic macrophytes and benthic algae were high (>50%) in the upper to middle reaches. The evaluation of organic matter contributions to SPM and detritus along the river–estuary continuum provided a baseline assessment of the nature and sources of potential food for consumers inhabiting different locations during different seasons. Incorporating SPM and detritus spatio-temporal variations in food web studies will improve our understanding of carbon flow in aquatic systems.

- Description: Peer tutors in higher education are frequently given vital teaching and learning work to do, but the training or professional development and support opportunities they are offered vary, and more often than not peer tutors are under-supported. In order to create and sustain teaching and learning environments that are better able to facilitate students’ engagement with knowledge and learning, the role of peer tutors needs to be recognised differently, as that of learning and teaching partners to both lecturers and students. Tutors then need to be offered opportunities for more in-depth professional academic development in order to fully realise this role. This paper explores a tutor development programme within a South African writing centre that aimed at offering tutors such ongoing and cumulative opportunities for learning and growth using a balanced approach, which included scholarly research and practice-based training. Using narrative data tutors provided in reflective written reports, the paper explores the kinds of development in tutors’ thinking and action that are possible when training and development is theoretically informed, coherent, and oriented towards improving practice.

- Description: Many coastal communities rely on living marine resources for livelihoods and food security. These resources are commonly under stress from overfishing, pollution, coastal development and habitat degradation. Climate change is an additional stressor beginning to impact coastal systems and communities, but may also lead to opportunities for some species and the people they sustain. We describe the research approach for a multi-country project, focused on the southern hemisphere, designed to contribute to improving fishing community adaptation efforts by characterizing, assessing and predicting the future of coastal-marine food resources, and codeveloping adaptation options through the provision and sharing of knowledge across fast-warming marine regions (i.e. marine ‘hotspots’). These hotspots represent natural laboratories for observing change and concomitant human adaptive responses, and for developing adaptation options and management strategies. Focusing on adaptation options and strategies for enhancing coastal resilience at the local level will contribute to capacity building and local empowerment in order to minimise negative outcomes and take advantage of opportunities arising from climate change. However, developing comparative approaches across regions that differ in political institutions, socio-economic community demographics, resource dependency and research capacity is challenging. Here, we describe physical, biological, social and governance tools to allow hotspot comparisons, and several methods to evaluate and enhance interactions within a multi-nation research team. Strong partnerships within and between the focal regions are critical to scientific and political support for development of effective approaches to reduce future vulnerability. Comparing these hotspot regions will enhance local adaptation responses and generate outcomes applicable to other regions.

- Description: In this article, I argue that Samuel Beckett’s The Unnamable evinces the kind of aesthetic ambivalence that Theodor Adorno, in Aesthetic Theory, ascribes to the artwork’s location both in and outside of society. By tracing the metaphors used in the narrator’s depiction of the act of narration, I demonstrate that this novel self-reflexively articulates and meditates on its ambivalent position in society. Thereafter, I relate the work’s suspicion of its medium, and therefore its estrangement from itself, to its critique of community’s norms of recognition, which are embedded in language. Finally, I reflect on the potential effect of the text’s aesthetic ambivalence on the reader.

- Description: To begin a review of the purpose(s) of ESD research, we must first ask the basic question of the purpose of research generally. Definitions of research normally centre on it comprising sys-tematic investigation which contributes to knowledge or under-standing of phenomena or a problem. A distinction is common-ly drawn between pure or basic research which focuses on understanding phenomena and issues, and applied research where the primary emphasis is on research which contributes to the solution of problems or some systemic improvement ra-ther than knowledge for its own sake. Some commentators see action research as a third category as it is predicated on the researcher being part of the research process which itself is committed to personal or social change. ESD research as an area of interest is perhaps unusual because it accommodates and crosses these categories. It also engages in philosophic research regarding cultural, worldview and ethical dimensions of sustainability education – critically important dimensions of ESD research, but not within the scope of this chapter. Re-search on – say – the relative effect of different pedagogies, or how a learning environ-ment affects learning, may be thought of as basic research, but at another level, ESD research is often purposeful beyond the accumulation of understanding about educational processes.

- Description: Publisher version , Globally, cultural values of natural resources are increasingly recognised as important for local natural resource management and conservation in and beyond parks. The tendency has been to focus on the direct-use rather than the cultural values and importance of natural resources. The cultural values underlying natural resources (directly or indirectly used) and various natural resource-based activities, and the implications for conservation, remain little explored. Drawing from household surveys, in-depth qualitative interviews, observations and secondary data, we explore the cultural significance of natural resources and different land-use practices among the San people bordering Kgalagadi Transfrontier Park in South Africa. Our findings illustrate that though cultural values are inextricably linked to resource use, they are not recognised by all community members. Further, cultural values arise from a diverse and sometimes conflicting array of values that punctuate individuals' lifestyles. A better understanding of context-specific cultural settings and the linkages between the cultural and material dimensions of resource use can lead to the development of interventions that can ensure effective conservation of both natural resources and culture.

- Description: Much as the Internet is beneficial to our daily activities, with each passing day it also brings along with it information security concerns for the users be they at company or national level. Each year the number of Internet users keeps growing, particularly in Africa, and this means only one thing, more cyber-attacks. Governments have become a focal point of this data leakage problem making this a matter of national security. Looking at the current state of affairs, cyber-based incidents are more likely to increase in Africa, mainly due to the increased prevalence and affordability of broadband connectivity which is coupled with lack of online security awareness. A drop in the cost of broadband connection means more people will be able to afford Internet connectivity. With open Source Intelligence (OSINT), this paper aims to perform a vulnerability analysis for states in Eastern Africa building from prior research by Swart et al. which showed that there are vulnerabilities in the information systems, using the case of South Africa as an example. States in East Africa are to be considered as candidates, with the final decision being determined by access to suitable resources, and availability of information. A comparative analysis to assess the factors that affect the degree of security susceptibilities in various states will also be made and information security measures used by various governments to ascertain the extent of their contribution to this vulnerability will be assessed. This pilot study will be extended to other Southern and Eastern African states like Botswana, Kenya, Uganda and Namibia in future work.

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.

- Description: This paper reports on the classroom languaging practices of a group of science teachers in rural and township schools in South Africa where the majority of learners learn through the medium of English, despite the fact that it is the home language of only a small minority; and learners’ poor English proficiency frequently restricts their access to the curriculum. The purpose of the study was to explore how these science teachers utilised the linguistic resources of the classroom – the learners’ home language and English – and if their practices might improve learners’ opportunity to learn science. A series of lessons for each teacher was videotaped and the teachers were interviewed on their language attitudes and practices.

- Description: This study outlines the development of linguistically based, language-specific measures of phonological awareness in isiXhosa and presents some preliminary findings. Hitherto, the study of phonological awareness has predominantly focussed on English, and to date phonological awareness in Bantu languages has not been adequately addressed. This study explicitly discusses the decisions made when developing a phonological awareness test for isiXhosa, which can easily be adapted for other Bantu languages. Our results show how participants perform better in syllable awareness tasks and how this is conditioned by the language-specific structures of isiXhosa. We demonstrate the need for micro-linguistic and language-specific considerations in the development of phonological awareness tests.

- Description: This article considers the application of the doctrine of separation of powers by the South African judiciary in a series of judgments flowing from applications and appeals concerning the disbanding of a specialised crime-fighting unit, the Directorate of Special Operations (‘DSO’, colloquially known as ‘the Scorpions’) and the establishment of another unit, the Directorate of Priority Crimes (‘DCPI’, colloquially known as ‘the Hawks’) through legislative enactment. 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: Pregnancy and mothering are enduring and central concerns of feminism. DiQuinzo (1999) sums this up in stating that “mothering is both an important site at which the central concepts of feminist theory are elaborated and a site at which these concepts are challenged and reworked.” Stephens (2004) argues, ‘…reproduction and mothering are central to theories of patriarchy and women’s unequal position in Western society…Childbirth can paradoxically be seen as both a cause of women’s subordinate position in society and a means of empowerment.’ Yet, despite the pivotal nature of pregnancy and mothering in feminist literature, there has been surprisingly little direct engagement by feminists in the area of ‘adolescent pregnancy.’ The engagement that there has been is a whisper in relation to the plethora of public health, medical, and psychological writings on ‘adolescent pregnancy.’ The feminists who have engaged with ‘adolescent pregnancy’ have, from their initial engagement and to varying degrees, tried to undermine simple interpretations of ‘adolescent pregnancy’ as a social problem and to link micro- and macro-level gender relations to occurrence of, and responses to, ‘adolescent pregnancy.’ Thus, for example, in the 1980s, Chilman (1985) asserted, ‘Sexism particularly afflicts programs and policies for these young people [unmarried teenage parents] as well as the behaviors that lead up to their becoming unmarried parents.’ In the 1990s, Pillow (1997), using a combination of feminist and postmodern theory, argued that ‘teen research and policy interventions can be understood as entrenched in the dilemmas of modernism, resulting often in normative assumptions that reflect our paradoxical attitudes and practices concerning female sexuality.’ More recently, Wilson and Huntington (2005) observed ‘adolescent pregnancy’ at a time when rates of fertility among young women are decreasing in ‘Western’ societies is ‘underpinned by changing social and political imperatives regarding the role of women in these countries.’

Understanding the constraints and identifying enabling aspects may help women academics to overcome obstacles in their career development and be more represented in academia and ultimately in society. This research was a case study undertaken at one higher education institution (HEI), Rhodes University (RU). The data was collected from institutional documents; questionnaire data from women academics at the HEI; and in-depth interviews with six women academics. The data indicate that mentoring is a strategy to enhance levels of self-esteem and research productivity and ultimately improve the representation of women in leadership and senior positions.
