- 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.

In search of optimal stocking regimes in semi-arid grazing lands : one size does not fit all

We argue that ‘one size does not fit all’ and that different stocking regimes are appropriate under different conditions. This paper is an attempt to move beyond polarization of the current debate towards a more integrative and flexible approach to grazing management. We propose five different conditions as major influences on grazing regimes: environmental variability and predictability; degradation and thresholds; property right regimes; discount rates; and market stability and prices. We suggest a lack of connection between the micro-economics literature and natural science and social-anthropological literature. It is timely to achieve greater integration around some key questions and hypotheses, and recognize that policy prescriptions at national or even regional levels are likely to have limited value due to context specificity.

- Description: The objective of this study was to compare the energy demands of manual harvesting tasks with the associated energy intake of the workers’. Fifty eight workers (29 Chainsaw Operators and 29 Stackers) were assessed in South Africa prior to, and during a ‘normal’ working shift. Habitual dietary analyses showed that the workers were eating less than 56% of the recommended daily allowance and were thus arriving at work with reduced energy stores. Heart rate responses were measured continuously during work and energy expenditure was predicted from the heart rate/oxygen uptake relationship obtained at a post-work progressive step up test completed by each worker. The data indicated that the tasks placed ‘moderate-to-heavy’ demands on the workers resulting in a significant imbalance between the energy demands of the tasks and the associated energy intake of the workers. Energy deficits were in excess of 8 000 kJ and workers lost, on average, 2.8% body mass during work while felling and cross-cutting, and 3.6% during stacking.

- 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: An estimated 27 million South Africans use indigenous medicines (Mander, 1997, Medicinal plant marketing and strategies for sustaining the plant supply in the Bushbuckridge area and Mpumalanga Province. Institute for Natural Resources, University of Natal, Pietermaritzburg, South Africa). Although herbal remedies are freely available in amayeza stores, or Xhosa chemists, for self-medication, little is known about the motivations of consumers. According to African belief systems, good health is holistic and extends to the person's social environment. The paper makes a distinction between traditional medicines which are used to enhance personal well-being generally and for cultural purposes, on the one hand, and medicines used to treat physical conditions only, on the other. Drawing on an eight-month study of Xhosa chemists in Eastern Cape Province, South Africa, in 1996, the paper identifies 90 medicines in stock which are used to enhance personal well-being. Just under one-third of all purchases were of medicines to enhance well-being. Remedies particularly popular included medicines believed to ward off evil spirits and bring good luck. The protection of infants with medicines which repel evil spirits is a common practice. Consumer behaviours indicate that the range of medicines available is increased by indigenisation of manufactured traditional medicines and cross-cultural borrowing. Case studies confirm that self- and infant medication with indigenous remedies augmented by indigenised medicines plays an important role in primary health care by allaying the fears and anxieties of everyday life within the Xhosa belief system, thereby promoting personal well-being.

- 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.

Using systematic case studies to investigate therapist responsiveness : examples from a case series of PTSD treatments

- Description: This article highlights the emerging literature on therapist responsiveness in psychotherapy and examines several concepts used to identify dimensions of responsiveness. Some methodological obstacles are identified to studying responsiveness in a systematic manner, and several examples of existing responsiveness research are reviewed. It is argued that meaningful theory on responsiveness has emerged from research methods that are qualitative and interpretive and that the writing of systematic case studies can be of particular importance since only the presentation of a case unfolding over time can disclose some of the more complex aspects of therapist responsiveness. Examination of a series of systematic case studies of the treatment of post traumatic case disorder in South Africa was used to derive a model for guiding therapist responsiveness with respect with what to focus on at a particular phase of the therapy within a particular session. Material from the cases is used to illustrate aspects of the model related to building social support for the client and promoting emotional processing of trauma memories. , Acknowledgements: This research was supported by grants from the National Research Foundation and the Joint Research Committee of Rhodes University. An earlier version of this paper was presented at the Conference of the Society for Psychotherapy Research in Barcelona in 2008 (Edwards, 2008).

- Description: This article highlights the emerging literature on therapist responsiveness in psychotherapy and examines several concepts used to identify dimensions of responsiveness. Some methodological obstacles are identified to studying responsiveness in a systematic manner, and several examples of existing responsiveness research are reviewed. It is argued that meaningful theory on responsiveness has emerged from research methods that are qualitative and interpretive and that the writing of systematic case studies can be of particular importance since only the presentation of a case unfolding over time can disclose some of the more complex aspects of therapist responsiveness. Examination of a series of systematic case studies of the treatment of post traumatic case disorder in South Africa was used to derive a model for guiding therapist responsiveness with respect with what to focus on at a particular phase of the therapy within a particular session. Material from the cases is used to illustrate aspects of the model related to building social support for the client and promoting emotional processing of trauma memories. , Acknowledgements: This research was supported by grants from the National Research Foundation and the Joint Research Committee of Rhodes University. An earlier version of this paper was presented at the Conference of the Society for Psychotherapy Research in Barcelona in 2008 (Edwards, 2008).

- Description: Douglas Livingstone's poem "Thirteen Ways of Looking at a Black Snake" is an artwork which addresses precisely these questions, seeking a manner of portraying the snake which is neither grossly appropriative nor wholly detached, neither ethically empty nor preachy. In its multi-angled structure, Livingstone attempts aesthetically "to establish and embellish ... a contact zone with the nonhuman animals who share our world with us, but accepting also that there exist considerable venues on either side of this contact zone that are, on the one hand, only human, and on the other hand, only nonhuman". Even in his more formally scientific work, Livingstone argues for the inevitability of such limits to knowledge, and for the value of the imagination in addressing them.

- 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: Software programs designed to calculate the tax liability of individuals and other types of tax entity are being designed and used with increasing frequency. Research done in the United States of America appears to indicate that these programs do not achieve any saving in time and, in fact, may take longer to use than to complete a tax return by hand. As the South African revenue collection system appears to be moving closer to a self-assessment system, where the calculation of tax owing will be the responsibility of the taxpayer, the research essay sets out to determine whether there is a saving in time when calculating a tax liability using a tax software program, instead of calculating it by hand. In addition, the research aims to determine how much time, on average, is saved or lost, using such a program, and whether there is any correlation between the time taken to perform a calculation by hand and that using the software program. It does so by comparing the average estimated time it would take to complete tax calculations for individuals by hand with the average time taken to complete the same tax calculations using a tax software program. The average time taken to do the calculations by hand is based on the time allocation given for questions by the authors of a published question bank for university students. The time taken using software is determined by using a stop-watch to time each question being processed. The results, subject to assumptions made in carrying out the research, show that there is a substantial saving in time using the software program. Based on the data, however, the results indicate a weak correlation between the estimated time taken to do a calculation by hand and the estimated time using the software program. Possible reasons for the weak correlation are discussed. A recommendation is also made for the standardization and certification of existing tax calculation software.

- 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.
