- Description: This paper employs a psychosocial framework to analyse the everyday lived experiences of a child and youth care worker in semi-rural South Africa. The aim is to provide a new perspective of care work by drawing on narrative analysis alongside a psychoanalytic approach to qualitative research. With an emphasis on the socially constructed nature of reality, the researcher aims to elucidate the rich unconscious depths of being a care worker and the dynamics of the intersubjective reality of care work. Employing a free association narrative interview technique allows the researcher to gain understanding of the narratives that the care worker draws on in the construction of his identity as a care worker. The use of a psychosocial approach enables the researcher to pay attention to both the social context that influences the narratives that he draws on, but also the psychological ‘pay offs’ of these constructions. Most notably, the study highlights how the care worker’s identity is mediated by a defended subjectivity and argues that his failures in mentalization might stem from the way he is treated as a care worker by other professionals as a result of their mindblindness. This maintains his narrative of invisibility, and the pervasive feeling of being misunderstood as a professional in his own right. The findings are discussed in terms of their contribution to understanding some of the challenges that CYCC care workers face. , Research Article (MA) -- Faculty of Humanities, Psychology, 2022

- Description: Retraction Watch maintains a "running list" of retracted papers on Covid-19 related research. By the end of September 2020, thirty-three retracted Covid-19 papers were listed. We analysed these retracted papers, focusing specifically on how they have been cited by review papers, and subsequently how they have penetrated and potentially distorted public discourse and legitimate research on Covid-19. The study demonstrates the need for more in-depth studies that focus on the phenomenon of citation pollution. We show that the "Covid-19 publication race", amplified by a pressure-to-publish research culture, distorted published science on Covid-19. We highlight the urgency to engage popular media and critical decision makers on how to distinguish between questionable and legitimate science. We also emphasise the importance of dealing with illegitimate research in a timely manner, both from a scholarly communications and research quality perspective. , Retraction Watch maintient une "liste courante" des articles rétractés sur les recherches liées au Covid-19. Fin septembre 2020, trente-trois articles rétractés sur le Covid-19 étaient répertoriés. Nous avons analysé ces articles rétractés, en nous concentrant spécifiquement sur la façon dont ils ont été cités par d'autres articles, et ensuite sur la façon dont ils ont pénétré et potentiellement faussé le discours public et la recherche légitime sur le Covid-19. L'étude démontre le besoin d'études plus approfondies qui se concentrent sur le phénomène de la pollution des citations. Nous montrons que la "course à la publication sur le Covid-19", amplifiée par une culture de la pression à la publication de la recherche, a déformé l'information scientifique publiée sur le Covid-19. Nous soulignons l'urgence d'engager les médias populaires et les décideurs critiques sur la manière de distinguer la science douteuse de la science légitime. Nous soulignons également l'importance de traiter rapidement les recherches illégitimes, tant du point de vue de la communication scientifique que de la qualité de la recherche. , Retraction Watch houdt een "lopende lijst" bij van ingetrokken papieren over Covid-19-gerelateerd onderzoek. Eind september 2020 waren drieëndertig ingetrokken Covid-19 papieren op de lijst geplaatst. We hebben deze ingetrokken papieren geanalyseerd, waarbij we ons specifiek hebben gericht op de manier waarop ze zijn geciteerd door review papers, en vervolgens op de manier waarop ze zijn doorgedrongen en mogelijk vervormd in het publieke discours en het legitieme onderzoek naar Covid-19. De studie toont aan dat er behoefte is aan meer diepgaande studies die zich richten op het fenomeen van de citatievervuiling. We tonen aan dat de "Covid-19-publicatierace", versterkt door een druk om te publiceren onderzoekscultuur, de gepubliceerde wetenschap over Covid-19 vertekend heeft. We benadrukken de urgentie om de populaire media en kritische besluitvormers te betrekken bij het maken van een onderscheid tussen twijfelachtige en legitieme wetenschap. We benadrukken ook het belang van het tijdig aanpakken van onrechtmatig onderzoek, zowel vanuit het oogpunt van wetenschappelijke communicatie als vanuit het oogpunt van de kwaliteit van het onderzoek.

- Description: Online appendix to the authors’ paper published in Social Indicators Research under the title: ‘The Best and Worst Times of Life for South Africans: Evidence of universal reference standards in evaluations of personal well‐being using Bernheim’s ACSA’. From the introduction: The Anamnestic Comparative Self‐Assessment (Bernheim’s ACSA), a measure of personal well‐being, was applied in the 10th annual round of the nationally representative South African Social Attitudes Survey (SASAS), a research infrastructure that has been administered by the Human Sciences Research Council (HSRC) since 2003. The target population for the survey was individuals aged 16 and over who live in South Africa. The multi‐stage sampling frame used by SASAS is based on census enumerator areas and data is weighted to the South African population using Statistics South Africa’s mid‐year population estimates as a benchmark. A total of 2’521 persons were interviewed in October and November 2012 by trained fieldworkers in their homes. Each interview was conducted in the respondent’s home language. ACSA was translated into the eleven official national languages. The SASAS 2012 study of ACSA follows on two earlier South African studies conducted in the Eastern Cape Province: a small pilot study conducted in 2005/6, followed by a larger representative community survey with some 1’000 respondents in 2007. ACSA uses a self‐anchoring scale. SASAS 2012 survey respondents were asked to think, first of their best period in life, and then of their worst period in life. These two periods represent the anchors of an 11‐ point scale running from ‐5 over a mid‐point (0), to +5. Text placed above the negative ‐5 anchor of the scale read: ‘As bad as the WORST period in my life’; text above the positive +5 anchor read: ‘As good as the BEST period in my life’. The respondents were asked to rate their present well‐being relative to these two periods on the scale. Their descriptions of these two extreme periods were recorded verbatim at the time of the interview. Later they were classified by domain in life based on the guidelines for the standard multiple‐choice format provided for recording ACSA anchors. This classification system is recommended by the ACSA scales’ initiator, Jan Bernheim and his colleagues. This online appendix to our Social Indicators Research article (‘The best and worst times of life for South Africans: Evidence of universal reference standards in evaluations of personal well‐being using Bernheim’s ACSA’) reports in greater detail the substantive contents of the survey responses to the ACSA anchoring process. The anchors of the ACSA scale serve as the reference standards for evaluating one’s life. Importantly, our 2012 SASAS survey respondents were invited to make explicit their choice of reference standards when reviewing their lives. This data offers a unique opportunity to gain rich insights into what matters for South Africans when they think about their quality of life and personal well‐being.

- Description: Africa is a latecomer to the Social Indicators Movement. The first social indicators for Third World countries were developed by outsiders and covered almost exclusively topics related to basic needs and development. In response to Kenneth Land's and Alex Michalos' historical assessment and their agenda for future 'social indicators/quality of life/well-being' research, the commentary traces how South Africa and sub-Saharan countries-with a little help from many friends who are pioneers in the movement-have succeeded in developing their own home-grown social indicators movement. Addressing some of the themes outlined in the agenda that Land and Michalos set for future research, the commentary discusses the importance of monitoring social change occurring in African society in a 'post-industrialized and much more globalized, and digitized-computerizedroboticized' era: How will new values and nom1s impact on the quality of life of future generations of African people?

The emergence of the South African farm crime novel : socio-historical crimes, personal crimes, and the figure of the dog

- Description: Crime fiction is an established and popular literary genre in South Africa that has gained international recognition and acclaim. The genre continues to expand and develop in terms of thematic concerns and experiments in form. One such notable development is the farm crime novel, which extends the tradition of the South African plaasroman. Recent texts, such as Elaine Proctor’s The Savage Hour and Karin Brynard’s Weeping Waters, quite deliberately set their respective murder mysteries on remote farms, and both novels particularise details of farm life. This article argues that the main concerns of the farm crime novel are, on one level, socio-historical – that is, the crimes perpetrated are the result of relationships to the land, land claims and land re-distribution, and the complex, evolving relationship between landowner and labourer. On another level, true to the conventions of crime fiction, the farm crime novel also explores interpersonal or intimate relationships that result in crimes of passion. Of particular interest is the observation that common to both thematic levels is a profound rendering of the link between human-animal relations and human-human relations. Drawing on Karla Armbruster’s work on the cultural significance of narratives about dogs and the need for more just and ethical relationships with animals, the article then demonstrates how this rendering occurs, often, through the figure of the dog. To conclude, some comments are offered on the position of the farm crime novel in a post-apartheid literary landscape

A discourse of disconnect : young people from the Eastern Cape talk about the failure of adult communications to provide habitable sexual subject positions

- Description: Face-to-face adult communication with young people about sexuality is, for the most part, assigned to two main groups of people: educators tasked with teaching schoolbased sexuality education that is provided as part of the compulsory Life Orientation (LO) learning area, and parents. In this paper, we report on a study conducted with Further Education and Training College students in an Eastern Cape town. Using a discursive psychology lens, we analysed data from, first, a written question on what participants remember being taught about sexuality in LO classes and, second, focus group discussions held with mixed and same-sex groups. Discussions were structured around the sexualities of high school learners and the LO sexuality education that participants received at high school. We highlight participants’ common deployment of a ‘discourse of disconnect’ in their talk. In this discourse, the messages of ‘risk’ and ‘responsibility’ contained in adult face-to-face communications, by both parents and LO teachers, are depicted as being delivered through inadequate or nonrelational styles of communication, and as largely irrelevant to participants’ lives. Neither of these sources of communication was seen as understanding the realities of youth sexualities or as creating habitable or performable sexual subject positions. The dominance of this ‘discourse of disconnect’ has implications for how sexuality education and parent communication interventions are conducted.

In this discourse, the messages of ‘risk’ and ‘responsibility’ contained in adult face-to-face communications, by both parents and LO teachers, are depicted as being delivered through inadequate or nonrelational styles of communication, and as largely irrelevant to participants’ lives. Neither of these sources of communication was seen as understanding the realities of youth sexualities or as creating habitable or performable sexual subject positions. The dominance of this ‘discourse of disconnect’ has implications for how sexuality education and parent communication interventions are conducted.

- Description: This study examined the use of Social Media/Web 2.0 for research support and it is guided by three objectives namely: a) to ascertain the uses of social media in academic institutions; b) to identify the challenges associated with social media use for research purposes and c) to provide experiences of social media application in selected African academic institutions. The study makes use of literature analysis in combination with personal and professional work experiences on the use of social media from librarians in four different countries. Institutional experiences of the four librarians showed that it is only Rhodes University Library that uses social media in its library, which is as a result of a formal social media strategy. For the other three universities, University of Education, Winneba Library in Ghana, Makerere University Library in Uganda and the University of Nigeria Library, the use of social media is not encouraging. They use it mostly for communication and interaction with colleagues. It was also discovered that there is no social media strategy available in these university libraries. Based on these findings, the study recommended the implementation of a social media strategy, appointment of social media librarians in these libraries, and continuing professional development of librarians to keep abreast with current trends. Web 2.0/Social Media is a new technology offering new options for African academic librarians in their research support role

Life orientation sexuality education in South Africa: gendered norms, justice and transformation

- Description: [From introduction] Research on sexual practices among young South Africans has proliferated in light of the national imperatives to challenge the spread of HIV/AIDS, gender-based violence and unwanted early pregnancies. It has been widely acknowledged that, in order to respond to these social problems, we need to understand the enmeshment of gender, class, age and other forms of social inequality, and how these are played out in ‘normal’ heterosexual relationships. Life Orientation (LO) sexuality education programmes have been viewed as key locations for incorporating education to challenge negative assumptions in respect of HIV/AIDS, gender-based violence and unwanted pregnancy and to promote safer, equitable and non-violent sexual practices. There is a paucity of work that interrogates the LO sexuality education programme in terms of gender norms, gender justice and gender transformation. In the handful of studies conducted on school-based sexuality education in South Africa, researchers have foregrounded a number of challenges, including the dominance of a guiding metaphor of danger and disease in the sexuality education component of LO manuals (Macleod, 2009); educators using a transmission mode of teaching to the exclusion of participation and experiential modes of learning (Rooth, 2005); educators understanding sexuality education as chiefly addressing the provision of information concerning, and prevention of, HIV/AIDS (Francis, 2011); teachers’ preference for abstinence-only education taught by means of a series of moral injunctions (Francis, 2011); and the avoidance of discussions of sexual diversity, and the endorsement of compulsory heterosexuality when same-sex relationships are mentioned (Francis, 2012). Recent research has also highlighted the variation in how teachers approach sexuality education. Francis and DePalma (2014) indicate that, while teachers may promote abstinence as the only appropriate choice for young people, they also recognise the value of teaching relationships and safe sex (aspects associated with comprehensive sexuality education). In their study, Helleve et al. (2009) report that Grades 8 and 9 LO teachers felt confident in teaching HIV and sexuality. This special issue of Perspectives in Education builds on this research by drawing together several papers that examine how LO or Life Skills sexuality programmes challenge and/or reproduce normative constructions of gender and gendered power relations. All the papers use qualitative research to locate these programmes within the complex contexts of their enactment, drawing attention to the multiple possibilities and limitations of such programmes. In the next section, we summarise the key problematics addressed in each of the papers. What curiosities drove the studies conducted by these researchers interested in gender dynamics in schools and LO or Life Skills sexuality education? Why are these curiosities important? We then highlight the key findings that emerged from these curiosities and the nuanced data collected. Finally, and most importantly in terms of the aims of this special issue, we address the ways in which a critical gender lens that facilitates gender transformation and gender justice could possibly be incorporated into LO or Life Skills sexuality programmes.

Sexual socialisation in Life Orientation manuals versus popular music: responsibilisation versus pleasure, tension and complexity

- Description: This paper compares two forms of sexual socialisation to which learners are exposed: the sexuality education components of the Life Orientation (LO) manuals and the lyrical content and videos of popular songs. We performed a textual analysis of the sexual subject positions made available in, first, the LO manuals used in Grade 10 classes and, second, the two songs voted most popular by the Grade 10 learners of two diverse schools in the Eastern Cape. Of interest in this paper is whether and how these two forms of sexual socialisation – one representing state-sanctioned sexual socialisation and the other learners’ chosen cultural expression that represents informal sexual socialisation – dovetail or diverge. Against a backdrop of heterosexuality and an assumption of the ‘adolescent-in-transition’ discourse, the main sexual subject positions featured in the LO manuals are the responsible sexual subject and the sexual victim. A number of sexualised subject positions are portrayed in the songs, with these subject positions depicting sex as a site of pleasure, tension and complexity. Although these two modes of sexual socialisation use different genres of communication, we argue that learners’ choice of songs that depict fluid sexual subject positions can help to inform LO sexuality education in ways that takes learners’ preferred cultural expression seriously and that moves away from the imperative of responsibilisation.

- Description: People who are voluntarily childless, or ‘‘childfree,’’ face considerable stigma. Researchers have begun to explore how these individuals respond to stigma, usually focusing on interpersonal stigma management strategies. We explored participants’ responses to stigma in a way that is cognisant of broader social norms and gender power relations. Using a feminist discursive psychology framework, we analysed women’s and men’s computer-assisted communication about their childfree status. Our analysis draws attention to ‘‘identity work’’ in the context of stigma. We show how the strategic use of ‘‘choice’’ rhetoric allowed participants to avoid stigmatised identities and was used in two contradictory ways. On the one hand, participants drew on a ‘‘childfree-by-choice script,’’ which enabled them to hold a positive identity of themselves as autonomous, rational, and responsible decision makers. On the other hand, they mobilised a ‘‘disavowal of choice script’’ that allowed a person who is unable to choose childlessness (for various reasons) to hold a blameless identity regarding deviation from the norm of parenthood. We demonstrate how choice rhetoric allowed participants to resist stigma and challenge pronatalism to some extent; we discuss the political potential of these scripts for reproductive freedom.

- Description: The need for monitoring the biological impacts of instream sediments has long been recognised, yet robust and scientifically defensible tools for doing so are still in the early stages of development because of the difficulties experienced by researchers in characterising the complicated mechanisms of biological effect elicited by sediment particles. Biological monitoring is one such tool, and this paper reports on the initial stages of a study to determine the most applicable approach for measuring the effects of instream sediments on aquatic macroinvertebrates in the South African context. In this first instance, the suitability of the rapid macroinvertebrate biomonitoring tool (the South African Scoring System) was investigated by determining the extent of the correlation between concurrently measured SASS metrics and turbidity data collected for the South African River Health Programme. All three SASS metrics – SASS score, number of taxa (NOT), and average score per taxon (ASPT) – were found to be significantly negatively correlated with turbidity, although variation in the data was high. Turbidity was found to be the major driver of change in ASPT. In contrast, electrical conductivity was the major driver of SASS scores and NOT, with turbidity a close second. When combined, electrical conductivity and turbidity accounted for 80 percent (SASS score) and 75 percent (NOT) of the variation in the regression model. Consequently, SASS metrics are a crude, but reliable, indicator of the negative biological implications of excessive instream sedimentation as measured by turbidity. A number of other potential biomonitoring approaches for detecting the impacts of fine sediment exposure are identified for further investigation: spatial analyses of macroinvertebrate assemblages; and the use of structural and functional metrics.

Second, we turn to Sarah McGrath’s account, which focuses on the use of imagery as a means to morally persuade. McGrath discusses 4 objections to the use of imagery, and outlines responses that may be used to legitimate the use of imagery in moral arguments. Assuming that we accept her account and that the invocation of affect has authority in the moral domain, we, using McGrath’s responses, examine whether the use of foetal imagery in anti-abortion campaigns is a legitimate instance of this practice.

‘… a huge monster that should be feared and not done’: lessons learned in sexuality education classes in South Africa

- Description: Research has foregrounded the way in which heterosexual practices for many young people are not infrequently bound up with violence and unequal transactional power relations. The Life Orientation sexuality education curriculum in South African schools has been viewed as a potentially valuable space to work with young people on issues of reproductive health, gender and sexual norms and relations. Yet, research has illustrated that such work may not only be failing to impact on more equitable sexual practices between young men and women, but may also serve to reproduce the very discourses and practices that the work aims to challenge. Cultures of violence in youth sexuality are closely connected to prevailing gender norms and practices which, for example, render women as passive victims who are incapable of exercising sexual agency and men as inherently sexually predatory. This paper analyses the talk of Grade 10 learners in nine diverse schools in two South African provinces, the Eastern Cape and the Western Cape, to highlight what ‘lessons’ these young people seem to be learning about sexuality in Life Orientation classes. We find that these lessons foreground cautionary, negative and punitive messages, which reinforce, rather than challenge, normative gender roles. ‘Scare’ messages of danger, damage and disease give rise to presumptions of gendered responsibility for risk and the requirement of female restraint in the face of the assertion of masculine desire and predation. We conclude that the role which sexuality education could play in enabling young women in particular to more successfully negotiate their sexual relationships to serve their own needs, reproductive health and safety, is undermined by regulatory messages directed at controlling young people, and young women in particular – and that instead, young people’s sexual agency has to be acknowledged in any processes of change aimed at gender equality, anti-violence, health and well-being.

- Description: Invertebrate macrofaunal biodiversity within intertidal seagrass meadows was investigated over a salinity gradient of <5–35 in the Knysna estuarine system (Garden Route National Park, South Africa). Rather than the classic gradual decline in species richness with distance from the mouth there were zones of considerable faunal stability separated by relatively sharp discontinuities. At the point upstream at which salinity regularly falls below 30, the rich, diverse and highly spatially variable downstream faunal assemblage changed to a less rich, less diverse and more uniform one that dominated the upstream stretch without any further upstream reduction in richness. Nevertheless, without loss of overall richness, assemblage composition changed, again rapidly, in the upper region of the upstream stretch to a zone dominated by the microgastropod Hydrobia, which otherwise occurs in the Knysna system only in highly sheltered regions of the downstream stretch where it is also dominant. The upstream faunal assemblage was a subset of that in the marine-influenced downstream region not a different replacing one. Position along the estuarine gradient accounted for 29% of total assemblage variation. Overall faunal abundance declined with distance upstream until the Hydrobia zone where it rose sharply, but there was no evidence of increase in density of those species remaining on putative release from competition.

- Description: Invertebrate macrofaunal biodiversity within intertidal seagrass meadows was investigated over a salinity gradient of <5–35 in the Knysna estuarine system (Garden Route National Park, South Africa). Rather than the classic gradual decline in species richness with distance from the mouth there were zones of considerable faunal stability separated by relatively sharp discontinuities. At the point upstream at which salinity regularly falls below 30, the rich, diverse and highly spatially variable downstream faunal assemblage changed to a less rich, less diverse and more uniform one that dominated the upstream stretch without any further upstream reduction in richness. Nevertheless, without loss of overall richness, assemblage composition changed, again rapidly, in the upper region of the upstream stretch to a zone dominated by the microgastropod Hydrobia, which otherwise occurs in the Knysna system only in highly sheltered regions of the downstream stretch where it is also dominant.

- Description: The net effect of pollen production on fecundity in plants can range from negative – when self-pollen interferes with fecundity due to incompatibility mechanisms, to positive – when pollen availability is associated with increased pollinator visitation and fecundity due to its utilization as a reward. We investigated the responses of bees to pollen and nectar rewards, and the effects of these rewards on pollen deposition and fecundity in the hermaphroditic succulent shrub Aloe tenuior. Self-pollinated plants failed to set fruit, but their ovules were regularly penetrated by self-pollen tubes, which uniformly failed to develop into seeds as expected from ovarian self-incompatibility (or strong early inbreeding depression). Bees consistently foraged for pollen during the morning and early afternoon, but switched to nectar in the late afternoon. As a consequence of this differential foraging, we were able to test the relative contribution to fecundity of pollen- versus nectar-collecting flower visitors. We exposed emasculated and intact flowers in either the morning or late afternoon to foraging bees and showed that emasculation reduced pollen deposition by insects in the morning, but had little effect in the afternoon. Despite the potential for self-pollination to result in ovule discounting due to late-acting self-sterility, fecundity was severely reduced in artificially emasculated plants. Although there were temporal fluctuations in reward preference, most bee visits were for pollen rewards. Therefore the benefit of providing pollen that is accessible to bee foragers outweighs any potential costs to fitness in terms of gender interference in this species.
