- Description: The purpose of this paper is to, survey the farm labour conditions in the Eastern Cape over approximately two decades and to note some of the conditions of service and the attitudes of employers, and the changes which have occurred in employment and wages paid. The main source for the latter period, and in particular 1973, is a farm labour survey conducted in conjunction with E.A. Thomson in the Eastern Cape. The survey relied entirely on the willingness of members of farm study groups and Farmers' Associations as well as interested individuals for its completion. Of the approximately 1020 pre-coded questionnaires which were posted to farmers throughout the Eastern Cape in June 1973, 303 were returned of which 299 were suitable for analysis.

- Description: In recent years there has been a growing literature that advocates various forms of participatory development. This is illustrated by the promotion of approaches/tools such as participatory rural appraisal (PRA), participatory technology development (PTD), and participatory process projects 1 These "new" approaches are fast taking on the form of a new generalised orthodoxy for solving development problems. It would seem from the perspective of some of the promoters of this orthodoxy that the problem of development is no longer one of not having the right approaches and methods, but one of getting recalcitrant policy makers, bureaucrats, academics to appreciate and adopt these new methods and techniques. My concerns with this new advocacy are that: i It does not relate to experience; ii It does not address issues of power structure and control over information and other resources in multiple and complex arenas of science and technology (S&T); iii By placing major emphasis on management approaches and tools, the new orthodoxy is cutting itself off from a critical reflective understanding of the deeper determinants of technical and social change. Unfortunately, I suspect that if this new orthodoxy does not develop a more critical reflective view of itself then, like previous dominant orthodoxies, it will soon have to develop a range of "escape hatches" to explain why these participatory approaches are not giving the results that their advocates promise. , AVOCADO series; v 06/95

- Description: Despite a multitude of international institutions on the African continent, worldwide Africa's multilateralism has generally received little attention. Yet, with the emergence of the African Union (AU) and its institutions, questions arise about its character. Will rhetoric and state symbolism take the place of substance or will the space opened up for democracy and civil society participation allow for greater democratically informed sustainability? With this in mind, the article addresses the issue to what extent the character of African multilateralism continues to display features of disconnectedness as opposed to those of transformation, where its institutions address issues of uneven development in concert with civil society concerns.

- Description: Publisher version , This study investigates how group size of Indo‐Pacific bottlenose dolphins (Tursiops aduncus) changes temporally, spatially, and/or with predominant behavior at two discreet sites along the Eastern Cape coastline of South Africa: Algoa Bay and the Wild Coast. The mean group size of bottlenose dolphins was large with an average of 52 animals. Significantly larger groups were observed in Algoa Bay ( = 60, range = 1–600) than off the Wild Coast ( = 32.9, range = 1–250). In Algoa Bay, the mean group size increased significantly over the study period, from an average 18 animals in 2008 to 76 animals in 2016. Additionally, the largest average and maximum group sizes ever reported both in South Africa and worldwide, were recorded in Algoa Bay (maximum group size = 600). Neither season nor behavior had a significant effect on mean group size at both sites. Similarly environmental variables such as the depth and substrate type also had no influence on group size. It remains unclear which ecological drivers, such as predation risk and food availability, are leading to the large groups observed in this area, and further research on abundance and distribution of both predators and prey is necessary.

- Description: publisher version , The concept of biocultural diversity, originally used to describe indigenous people and their ways of using and managing natural resources, has more recently been applied within the urban context to understand the variability of interactions between humans and nature. Significant progress has been made internationally in acknowledging the need to preserve and maintain green spaces in urban environments. Current efforts to address the need for greening urban areas in South Africa primarily focus on the establishment and maintenance of botanical gardens and parks as well as various green belts within the urban landscape. South Africa's urban areas are overwhelmingly shaped by the historical segregation of space and stark disparities in wealth. The distribution, quality, and extent of urban green spaces reflect this. Many township dwellers do not have access to these amenities and their interactions with nature are thus usually constrained to access to municipal commonages. This article explores how areas of natural vegetation in municipal commonages on the outskirts of urban centers in South Africa continue to offer places of cultural, spiritual, and restorative importance to Xhosa-speaking township dwellers. A case study from Grahamstown, an urban center in the Eastern Cape with a population of around 80,000, illustrates how ability to access and move through such places contributes to people's well-being, identity formation, and shared heritage. A case is made for adopting a biocultural diversity approach to spatial planning and urban development within the South African context.

- Description: Concerns about ecological degradation and social inequalities have prompted increasing calls for stewardship in the social–ecological systems and sustainability science literature. However, how can the ideals of stewardship be realised in practice? The links between the theory and practice of stewardship are under-developed, and research to support place-based stewardship practice is limited. We therefore bring together complementary perspectives to guide research on place-based stewardship practice in the context of multifunctional landscapes. We unpack and synthesise literature on stewardship, landscapes, and collaboration for natural resource management, and highlight the ways in which the pathways approach can deepen research on collaboration and stewardship practice. We propose landscapes as a suitable level of analysis and action for stewardship. Since all landscapes are multifunctional, we argue that collaboration among multiple stakeholders is a necessary focus of such research. Our analysis reveals that existing theory on collaboration could be deepened by further research into the agency of individual human actors, the complex social–relational dynamics among actors, and the situatedness of actors within the social–ecological context. These factors mediate collaborative processes, and a better understanding of them is needed to support place-based stewardship practice. To this end, the pathways approach offers a waymark to advance research on collaboration, particularly in the complex, contested social–ecological systems that tend to characterize multifunctional landscapes.

- Description: Six indicators were investigated for South African sardine Sardinops sagax and anchovy Engraulis encrasicolus: mean length of catch, length-at-50% maturity, total mortality, exploitation rate, ratio of bycatch, and centre of gravity of commercial catches. Sardine length-at-50% maturity is the most promising as a descriptive indicator because it is positively correlated with population size for an extensive time period (1953–2005). The remaining indicators were limited by shorter data-series (1984–2005). However, mean length of catch, ratio of bycatch and exploitation rate were found to be useful when considered in conjunction with other indicators. The centre of gravity of commercial sardine catches has shown a significant eastward shift from the West Coast, whereas that of anchovy has remained off that coast. Ratio of bycatch indicates that school composition is a reliable descriptive indicator of relative abundance in the two species. Fewer indicators for anchovy were useful, which is attributed to this species’ flexible life-history pattern.

- Description: In this paper, first results from a national Global Positioning System (GPS) based total electron content (TEC) prediction model over South Africa are presented. Data for 10 GPS receiver stations distributed through out the country were used to train a feed forward neural network (NN) over an interval of at most five years. In the NN training, validating and testing processes, five factors which are well known to influence TEC variability namely diurnal variation, seasonal variation, magnetic activity, solar activity and the geographic position of the GPS receivers were included in the NN model. The database consisted of 1-min data and therefore the NN model developed can be used to forecast TEC values 1 min in advance. Results from the NN national model (NM) were compared with hourly TEC values generated by the earlier developed NN single station models (SSMs) at Sutherland (32.38°S, 20.81°E) and Springbok (29.67°S, 17.88°E), to predict TEC variations over the Cape Town (33.95°S, 18.47°E) and Upington (28.41°S, 21.26°E) stations, respectively, during equinoxes and solstices. This revealed that, on average, the NM led to an improvement in TEC prediction accuracy compared to the SSMs for the considered testing periods.

- Description: The Messum complex of NW Namibia, a part of the Paraná–Etendeka volcanic province, consists of a dominantly felsic central core, surrounded by older gabbros. The igneous rocks of the core can be divided, in order of decreasing age, into (1) a sub-alkaline suite, (2) an outer quartz syenite suite, and (3) an inner silica-undersaturated suite dominated by nepheline syenite. Compositional differences within the quartz syenite suite can be explained by fractional crystallization, but Sr- and O-isotope data indicate that these rocks contain a significant crustal component.

- Description: The development of automated servers to predict the three-dimensional structure of proteins has seen much progress over the years. These servers make calculations simpler, but largely exclude users from the process. In this study, we present the PRotein Interactive MOdeling (PRIMO) pipeline for homology modeling of protein monomers. The pipeline eases the multi-step modeling process, and reduces the workload required by the user, while still allowing engagement from the user during every step. Default parameters are given for each step, which can either be modified or supplemented with additional external input. PRIMO has been designed for users of varying levels of experience with homology modeling. The pipeline incorporates a user-friendly interface that makes it easy to alter parameters used during modeling.

- Description: Studies of projected agro-climatic variability on the productivity of smallholding farming livelihoods have been evaluated by indirect methods using simulation models on country or regional basis but few have been done at the community level. This study explores direct observation of the impact of soil and climate factors on crop and livestock livelihood systems in the three major agro-ecological zones of the Eastern Cape Province of South Africa. It also analyzed their influence on small farmers’ choices of agrarian livelihood activities and the lessons learned for the suitability of agro-ecologically integrated agriculture as part of agrarian and food security reforms needed among small farming households in rural communities of South Africa. The impact of soil and rainfall on the crop and livestock livelihood choices of smallholders in the three major agro-ecological zones were explored. A cross-sectional survey was carried out among 223 smallholding farming households during the harvesting period of rain-fed farming season. Data on household livelihood activities were processed in monetary terms and subjected to gross margin and cost/benefit analysis. Geographic information system (GIS) mapping and statistical analysis were used to determine the association of smallholder maize revenue with agro-climatic variation. The results indicated that crop-based activities performed better in the Grassland zone, while livestock activities performed better in the Savanna zone. Small farms in the Karoo can only productively engage in livestock production. The results also showed that farming activities that combined more vegetable crops yielded greater profits than other field crops. Furthermore, the results indicate that the mixed cropping method remains one of the strategies for breaking-even and risk-bearing effort used by the smallholder farmers considering its cost-sharing benefits. Geographical information system (GIS) mapping further indicates that smallholders’ farming activity was not only affected by soilclimatic factors but by their management skills as well. We recommend agroecologically adapted policies and incentives for agriculture-based livelihood activities and intensified mixing of cropping systems among the smallholder farming households in the study area.

Mortgage bonds and the right of access to adequate housing in South Africa: Gundwana v Stoke Development and Others 2011 (3) SA 608 (CC)

- Description: This article offers a critique of Gundwana v Stoke Development and Others 2011 (3) SA 608 (CC), a case in which the Constitutional Court of South Africa found it to be unconstitutional for the registrar of a high court to declare immovable properties specially executable when ordering a default judgement, to the extent that such an order "permitted the sale and execution of a home of a person". The Court interpreted the property clause in section 25, access to right to housing in section 26 of the Constitution, as mandating "further judicial oversight" in all cases where execution is levied against residential property. The article raises some of the shortcomings of this interpretive scheme and suggests that constitutional values, when used to curtail or enlarge obligations of parties to a mortgage bond, must take into account the general rights and duties which the parties assumed at the signing of the agreement; the circumstances of each of the parties at the time of execution and ascertained through a careful evaluation based on a clearly articulated set of principles, and the nature of constitutional rights themselves. The article argues that, whereas there may be circumstances in which a debtor may need protection, rather than impose a blanket abrogation of procedures allowing for expedient disposal of uncontested claims, the court should instead have considered the establishment of further procedural safeguards.

- Description: publisher version , The origins of the intellectualisation of written isiXhosa literature are often attributed to the missionaries John Ross and John Bennie. They set up a printing press in the Tyhume Valley which later became known as Lovedale Press. They introduced written isiXhosa in 1823 and for this they are acknowledged as the first to write and publish in isiXhosa. This article attempts to trace this intellectualisation process of isiXhosa literature, concentrating on a critique and assessment of the life-long work of Professor Jeff Opland, who has contributed enormously to the present understanding of both oral and written isiXhosa literature. It is argued in this article that his corpus of books and academic articles require some contextualisation within the broader debate of the continued intellectualisation of isiXhosa language and literature. Reference is also made to the Opland isiXhosa literature archive and its contribution to the further intellectualisation of isiXhosa literature. It is suggested in this article that Opland is one of the greatest contributors to academic debates concerning isiXhosa literature and history. Izibongo or oral poems written by, and about Jeff Opland are analysed to further enhance the context of his contribution.

- Description: The growing interest and access to massively multiplayer online role-playing games (MMORPG) has opened up significant new scope for educational methodologies, from standard language teaching options through to formalising the skills that a ‘player’ develops through their quests and other activities. This scope is extensive and has created numerous opportunities for innovation both within education and the world of work. This is evidenced by the increasing presence of educational establishments in the virtual world, with Second Life being the most popular for conventional educational purposes. In Second Life and many other realms participants are earning some income and in some cases enjoying a reasonable living from online activities, while developing their skills base. These MMORPGs may open opportunities for promoting language acquisition provided this is located within a suitably attractive realm; ‘players’ would then engage in activities that would contribute to their abilities to use the indigenous languages in everyday life. This article explores how such a system could be developed and the likely contribution it could make to promote a multilingual environment at school and post school levels. Further, it will identify the implications for the future of teaching and learning through the harnessing of MMORPGs.

Disjunctions in the Diptera (Insecta) fauna of the Mediterranean Province and southern Africa and a discussion of biogeographical considerations : ecological overview article

- Description: This paper explores disjunctions in the Diptera fauna of the Mediterranean Province and southern Africa, drawing from eight families of Diptera, the more ancient Psychodidae and Vermileonidae, and the more recent Acroceridae, Asilidae, Bombyliidae, Dolichopodidae, Pipunculidae and Sciomyzidae. Information from recent published revisions is geo-referenced and plotted onto maps using GIS software. These distribution patterns are interpreted and probable means and routes of dispersal between the two regions are discussed. The concept of an Afrotropical sub-Saharan boundary is outlined and it is argued that although the vast, arid and virtually abiotic Sahara acts as a barrier to dispersal today, relict floral and faunal populations of Mediterranean provincial origin still occur on the Hoggar and Tibesti Mountains of the central Sahara, indicating that the aridification of the Sahara is a very recent event. The presence of extensive palaeolakes formerly covering ca 10% of the present-day Sahara is regarded as evidence in support of this hypothesis. These lakes and their associated catchments, situated in basins between the central Saharan mountains, could clearly have acted as a humid route of dispersal as recently as 4000 BP, when these lakes began to recede, and this route is here regarded as a "central high Africa corridor"; a filter-bridge between the Mediterranean Province and southern Africa. Examples of Mediterranean provincial species of Ephydridae and the muscid genus Lispe Latreille, 1796, occurring as far south as the AÏr Massif in northern Niger are cited as examples of relict montane Diptera of Mediterranean provincial origin in the southern Hoggar Mountains; these groups being associated with the margins of standing water. Balinsky's (1962) concept of an "arid corridor" is also re-examined, using examples from the larger, less mobile Diptera, and it is concluded that such a pattern may not be the result of aridity, but represent an "eastern high Africa corridor", broadly corresponding to the "African Supers well". Other perceived distribution pathways between the Holarctic and Afrotropical Regions are mapped. Anemochore dispersal is considered, and the extent of the Afrotropical Region is discussed. Mediterranean tectonic evolution on both a globe of constant size and on a smaller Jurassic globe is also considered. It is concluded that if all the transitional zones between the zoogeographical regions are to be given more-or-less equivalent treatment, we must avoid setting boundaries based on earlier faunal distributions. For this reason the current boundary between the Palaearctic and Afrotropical Regions, arbitrary as it is, should be retained, despite evidence suggesting recent continuity between sub-Saharan Africa, North Africa and the Arabian Peninsula, corresponding broadly to the African and Arabian lithospheric plates.

- Description: This paper sets out to reflect that contemporary schools of thought are unable to explain the great recession of 2008. The Great Recession 2007-2009 and the long, slow recovery from it serve as reminders of the difficulty of explaining business cycles. Macroeconomists of all varieties have been humbled by these events and by our inability to predict or to design policies that moderate the effects. Paul Krugman (2009) and John Cochrane (2010) are examples of how two schools of thought have struggled with the issue. Many theories of business cycles exist, without any being comprehensive; none are able to account for all important characteristics. Macroeconomic theory continues to explore stylised facts for explanatory power. The whole sub-discipline of “macroeconomics” is premised on the belief that the standard microeconomic tools are not of much use in understanding the dynamics of growth and business cycles. Even with the rational expectations revolution purporting to set macroeconomics back on microfoundations, the language of aggregate supply and demand, over-simplified versions of the Quantity Theory of Money, and the aggregative analytics of the Keynesian cross and simple models of functional finance still fill the textbooks and inform most policy debates. The neglect of capital theory in particular has removed the important elements of time and money from Macroeconomics. The main approaches to Macroeconomics are compared and their lack of a firm micro foundation exposed. The dissatisfaction with macroeconomics can be resolved by taking a more capitalbased approach. This will allow for macro elements such as time and money while reintroducing the entrepreneur into macroeconomic theory. Relative prices, especially intertemporal prices can then again take their rightful place in explaining the business cycle.

- Description: publisher version , Bernstein’s concept of classification and framing links notions of knowledge, democracy and social justice, providing a perspective from which to address critical questions of what knowledge is produced, who has access to it, and how knowledge is distributed. Bernstein’s conceptual framework is used to inform an analysis of national policies steering knowledge production and knowledge transfer in the UK, and the changing practices and values associated with knowledge production and knowledge transfer in two UK institutional case study universities. The analysis reveals how reputational and financial consequences of the formal assessment of research quality interacts with the institutional and disciplinary contexts of research units to differently shape what knowledge is valued and produced, and with whom it is shared. Five discursive areas, each involving a complex set of classifications (power) and framings (control) are identified, namely: the national research assessment framework; the economic value of research; discourses of social and academic values; academic freedoms; and mixed-discipline research and the interdisciplinary nature of real world problems. Though competing and sometimes contradictory values seem to underlie academics’ knowledge work, it seems that the strong framing for knowledge production and knowledge exchange provided by national policies steers staff efforts towards economised codes of knowledge. The conclusion suggests that such a strong steer does not value social transformation in all its diverse non-economistic dimensions and limits universities’ potential to transform societies to further social justice.
