- Description: As much as people benefit from the ecosystem services provided by nature, ecosystem disservices also impact daily lives. This is especially true for many urban communities in the Global South due to (1) the often greater diversity of ecosystem disservices and (2) higher vulnerabilities, which together can lead to greater impacts of ecosystem disservices in many Global South settings. This chapter provides an overview of the current understandings of urban ecosystem disservices and their assessment and management with an emphasis on the Global South, albeit with reference to the Global North where useful. This overview reveals a lack of detailed and systematic empirical research on urban ecosystem disservices generally, but even more so in the Global South, despite the greater diversity and vulnerability in Global South settings. This needs to be acknowledged in urban ecology framings of urban dynamics in the Global South and translated into better integration of both ecosystem services and disservices within common research, policy or management frameworks. It is only through such integration that appropriate context-relevant policy directions and management options can be identified, thereby promoting the wellbeing of urban citizens in the Global South.

- Description: Heat shock protein 90 (HSP90) is an evolutionarily conserved chaperone protein that controls the function and stability of a wide range of cellular client proteins. Fibronectin (FN) is an extracellular client protein of HSP90, and exogenous HSP90 or inhibitors of HSP90 alter the morphology of the extracellular matrix. Here, we further characterized the HSP90 and FN interaction. FN bound to the M domain of HSP90 and interacted with both the open and closed HSP90 conformations; and the interaction was reduced in the presence of sodium molybdate. HSP90 interacted with the N-terminal regions of FN, which are known to be important for matrix assembly.

- Description: Combating malaria is almost a never-ending battle, as Plasmodium parasites develop resistance to the drugs used against them, as observed recently in artemisinin-based combination therapies. The main concern now is if the resistant parasite strains spread from Southeast Asia to Africa, the continent hosting most malaria cases. To prevent catastrophic results, we need to find non-conventional approaches. Allosteric drug targeting sites and modulators might be a new hope for malarial treatments. Heat shock proteins (HSPs) are potential malarial drug targets and have complex allosteric control mechanisms. Yet, studies on designing allosteric modulators against them are limited. Here, we identified allosteric modulators (SANC190 and SANC651) against P. falciparum Hsp70-1 and Hsp70-x, affecting the conformational dynamics of the proteins, delicately balanced by the endogenous ligands. Previously, we established a pipeline to identify allosteric sites and modulators. This study also further investigated alternative approaches to speed up the process by comparing all atom molecular dynamics simulations and dynamic residue network analysis with the coarse-grained (CG) versions of the calculations. Betweenness centrality (BC) profiles for PfHsp70-1 and PfHsp70-x derived from CG simulations not only revealed similar trends but also pointed to the same functional regions and specific residues corresponding to BC profile peaks.

- Description: This chapter introduces ideas from the Legitimation Code Theory dimension of ‘Semantics’ that have been influential in shaping research into academic discourse and theory in systemic functional linguistics (SFL). The concepts of ‘semantic gravity’ and ‘semantic density’ explore the context-dependence and complexity of meanings. These concepts have been used widely by applied systemic linguists in research into education and beyond. They have also helped spur theoretical development in the framework of SFL – specifically Martin’s meta-concepts of ‘mass’ and ‘presence’. This chapter is an introduction to the concepts and illustration of how they are being used in research into accessing academic discourse. It begins by briefly highlighting how LCT concepts attend to two key obstacles to supporting knowledge-building: knowledge-blindness and shallow theorizing. Second, the key concepts are defined. Third, the chapter demonstrates how these LCT concepts are being used to explore education, drawing on studies of student assessments and teaching practice. These analyses suggest that ‘semantic waves’, where knowledge is transformed between relatively decontextualized, condensed meanings and context-dependent, simplified meanings, are the key to student achievement and enabling knowledge-building in teaching practice. How these concepts are being widely used to explore organizing principles of diverse practices in education beyond classrooms, including research and curriculum, is discussed, revealing the widespread, complex and suggestive nature of ‘semantic waves’ and their implications for understanding how to promote access to academic discourse.

Infecting the city: site-situational performance and ambulatory hermeneutics

- Description: This article proposes the term ‘site-situational’ art or performance as a meaningful shift beyond ‘site-specificity’ and as a way to develop forward-moving and relational understandings of place. While place falls prey to Western, modernist stereotypes of closed, territorial geographic systems, site-situational readings, radical forms of ‘recognition’ and ambulatory hermeneutics enable an understanding of place as a wandering signifier, a trickster figure, and an in-the-moment conversation between environments and living beings. Through an analysis of the 2009 Infecting the City performing arts festival in South Africa, the article links site-situational performance to situational understandings of identification in the context of migration and xenophobia. It connects the participatory creative resistance aspired to by the Situationists that transforms situations rather than just recognises them, to the potential mutuality that can be experienced when one recognises oneself in the face of a ‘foreigner’ as well as the potential culpability that accompanies pro-active recognition-on-the-run.

- 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.

Conscientious objection to performing same-sex marriage in South Africa

- 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 , Drawing on the case of a small South African university which espouses a social justice approach to transformation, this chapter considers the possibilities and challenges created for student feedback within an institutional context that gives the individual lecturer a large degree of autonomy in evaluation. The chapter looks at some of the dominant perceptions of student feedback in addition to how it is collected and utilised, by referring to the institution’s policies and guideline documents; institutional research conducted with course coordinators; responses elicited from 40 lecturers on the issues outlined in this chapter; the author’s own reflections as a staff developer in the institution; and specific examples of good practice from lecturers situated within social science disciplines. The emerging concerns which structured this discussion are: the impact of student feedback on improving quality; enabling student voice; increasing student ownership; and the educational value of evaluation processes.

- Description: What is the role of the judge in the conduct of a trial? Can he or she engage counsel in legal argument and ask questions on legal issues without breaking the brittle bond of justice or be said to have 'descended into the arena'? Assuming that these actions are permissible, at what point will the judge's dialogue with counsel or line of questioning go beyond permissible limits? These are the questions with which this article grapples. Based on an analysis of the Constitutional Court decisions in State v Basson (2) 2007 (1) SACR 566 (CC) and Bernert v ABSA Bank Ltd 2011 (3) SA 92 (CC), and several Supreme Court of Appeal and other Commonwealth decisions, the article explores the circumstances in which the recusal of judges has been sought, or judicial decisions have been challenged on appeal on the basis of an allegation that there have been violations of the principle of fair hearing as enshrined in the Constitution. The article draws on the 'apprehension of bias' jurisprudence to establish the utility of the presumption of impartiality and the hybrid test of double-reasonableness in contexts where a judge's conduct is in question. The article concludes that the dialogue between the bench and bar is a useful component of adjudication in our adversarial system and should be limited by the rules of impartiality only in very exceptional circumstances.

Newspaper literacy and communication for democracy: is there a crisis in South African journalism?

- Description: Media theorists such as Barnett (2002), Buckingham (1997 & 2000) and Sampson (1999) describe a perceived crisis hindering the media’s ability to inform citizens for participation in democracy. One of the symptoms and causes of this crisis, they argue, is that the media use language that many citizens cannot understand. This article draws on theories and methodologies from linguistics to investigate whether this claim holds true for South African newspapers. The concept of the crisis in journalism is deconstructed in the light of Street’s (1984) ideological model of literacy. In a pilot study, multiple readability tests were conducted on one article from each of three newspapers, Business Day, The Herald and Daily Sun. The findings of these tests, and a systemic functional grammar analysis of cohesion and lexical density in the three articles, show that all three newspapers tailor their language to fit their target markets. This, triangulated with the rapid growth in readership of the Daily Sun and the more modest growth of The Herald, suggests that many South Africans are better informed for participation in democracy than in the past, although newspapers can do more to help readers learn a plurality of literacy practices.

- Description: We the Trade Union representatives here present firmly commit ourselves to a unified democratic South Africa, free of oppression and economic exploitation. We believe that this could only be achieved under the leadership of a united working class. Our history has taught us that to achieve this goal we will have to carry out the following tasks : Organise the unorganised and build effective trade unions based on the democratic organisation of workers in the factories, mines, shops, farms and other workplaces. Organise national industrial trade unions, financed and controlled by their worker members through democratically committees. Unify these industrial unions into a national worker controlled federation. Combat the divisions amongst the workers of South Africa and unite them into a strong and confident working class. Encourage democratic worker organisation and leadership in all spheres of our society together with other progressive sectors of the community. Reinforce and encourage progressive international worker contact and solidarity so as to assist one another in our struggle. We call on all those who identify with this commitment to join us and the workers whom we represent, as comrades in the struggle ahead. We call on all trade unions to strive to unite their members in their ranks without discrimination and prejudice, and therefore resolve that this federation shall determinedly seek to further and protect the interests of all workers and that its guiding motto shall be the universal slogan of working class solidarity: "An injury to one is an injury to all".

- Description: Privatisation is when government hands over the management or assets of government services to private interests. Privatised services don't provide well for the poor, who can't pay, because private interests must make profits. Government says it will ensure the poor get good services through contracts and regulations - but it doesn't have capacity to enforce them. Privatisation makes it harder to maintain cross subsidies. Cross subsidies mean rich communities or industry pay more, so that poor households can pay less. Getting rid of cross-subsidies tends to make the prices for services for the poor go up. Privatised companies don't take the broader economic needs of the country into account, for instance by buying goods locally as a way to create jobs, and providing affordable services in remote regions.

Numerically the union has grown from 26 000 signed up members to over 40 000 in the period under review. But it is not only in numbers that TGWU has grown. The period has been one in which new structures of the union have been built, and where new organisational direction has been sought in all sectors. The period has been one during which for the first time in four years, the union has not had to divert its attention to putting into effect complex mergers and transfers of membership. It has also of course been a period charged by major national political developments - from the passing of the Labour Relations Amendment Act in September 1988, to the release of seven ANC leaders from Robben Island in October of this year.

- Description: Jane G, first appeared as a series in Solidarity, the mouthpiece of the Cape Action League. The series was read by activists in community, student, youth and worker organisations. At the request of readers, the Cape Action League decided to publish the series as a booklet. The book is written in easy English in order for it to be used by workers and their allies as an instrument for active struggle against all forms of oppression and exploitation. The story of Jane G has its roots in the daily experiences of an ordinary black working mother living in South Africa/Azania. She is the mother you meet at the bus stop, meet in the taxi, talk to at the corner shop or prayer meeting. In this series, Jane G’s struggle is typical of the millions of workers suffering a similar fate in our country. Jane speaks of the hardship she faces under the exploitative cycle of earning low wages and paying high rents. The burden of working long hours and paying high prices for basic food in order to look after her family. She finds relief by joining the Clothing Workers’ Union which organises workers at the Rex-Tex factory where she works.
