- Description: Discursive constructions of abortion are embedded in the social and gendered power relations of a particular socio-historical space. As part of research on public discourses concerning abortion in South Africa where there has been a radical liberalisation of abortion legislation, we collected data from male group discussions about a vignette concerning abortion, and newspaper articles written by men about abortion. Our analysis revealed how discourses of equality, support and rights may be used by men to subtly undermine women's reproductive right to ‘choose’ an abortion. Within an Equal Partnership discourse, abortion, paired with the assumption of foetal personhood, was equated with violating an equal heterosexual partnership and a man's patriarchal duty to protect a child. A New Man discourse, which positions men as supportive of women, was paired with the assumption of men as rational and women as irrational in decision-making, to allow for the possibility of men dissuading women from terminating a pregnancy. A Rights discourse was invoked to suggest that abortion violates men's paternal rights.

- Description: In 1962 John moved south to Johannesburg, but that bustling city held few attractions for him and he moved further south, to the cathedral city of Grahamstown. Grahamstown, with its nineteenth century Gothic cathedral, elegant Georgian buildings, and distinctive grandeur of Rhodes University, St Andrew's College and other buildings designed by Herbert Baker and his colleagues, suited John. He particularly enjoyed the academic, social, artistic and dramatic life of the community, where many older members of society were distinguished old-Africa hands. John thoroughly enjoyed Grahamstown where, in the partnership of Hoskins and English, he made his mark in the restoration and extension of many significant buildings. His addition to the Anglican chapel at Hog's Back is a masterpiece, as is his incorporation of the old fayade into the rebuilding and extension of the Magistrates' Court.

Observables in a lattice Universe : the cosmological fitting problem

- Description: We explore observables in a lattice Universe described by a recently found solution to Einstein field equations. This solution models a regular lattice of evenly distributed objects of equal masses. This inhomogeneous solution is perturbative, and, up to second order in a small parameter, it expands at a rate exactly equal to the one expected in a dust dominated Friedmann-Lema^itre-Robertson-Walker (FLRW) model with the equivalent, smoothed, energy density. Therefore, the kinematics of both cosmologies are identical up to the order of perturbation studied. Looking at the behaviour of the redshift and angular distance, we find a condition on the compactness of the objects at the centre of each cell under which corrections to the FLRW observables remain small, i.e. of order of a few percents at most. Nevertheless, we show that, if this condition is violated, i.e. if the objects are too compact, our perturbative scheme breaks down as far as the calculations of observables are concerned, even though the kinematics of the lattice remains identical to its FLRW counter-part (at the perturbative order considered). This may be an indication of an actual fitting problem, i.e. a situation in which the FLRW model obtained from lightcone observables does not correspond to the FLRW model obtained by smoothing the spatial distribution of matter. Fully non-perturbative treatments of the observables will be necessary to answer that question.

Plasmodium falciparum Hsp70-x : a heat shock protein at the host-parasite interface

- Description: Plasmodium falciparum 70 kDa heat shock proteins (PfHsp70s) are expressed at all stages of the pathogenic erythrocytic phase of the malaria parasite lifecycle. There are six PfHsp70s,all of which have orthologues in other plasmodial species, except for PfHsp70-x which is unique to P. falciparum. This paper highlights a number of original results obtained by a detailed bioinformatics analysis of the protein. Large scale sequence analysis indicated the presence of an extended transit peptide sequence of PfHsp70-x which potentially directs it to the endoplasmic reticulum (ER). Further analysis showed that PfHsp70-x does not have an ER-retention sequence, suggesting that the protein transits through the ER and is secreted into the parasitophorous vacuole (PV) or beyond into the erythrocyte cytosol. These results are consistent with experimental findings. Next, possible interactions between PfHsp70-x and exported P. falciparum Hsp40s or host erythrocyte DnaJs were interrogated by modeling and docking. Docking results indicated that interaction between PfHsp70-x and each of the Hsp40s, regardless of biological feasibility, seems equally likely. This suggests that J domain might not provide the specificity in the formation of unique Hsp70-Hsp40 complexes, but that the specificity might be provided by other domains of Hsp40s. By studying different structural conformations of PfHsp70-x, it was shown that Hsp40s can only bind when PfHsp70-x is in a certain conformation. Additionally, this work highlighted the possible dependence of the substrate binding domain residues on the orientation of the α-helical lid for formation of the substrate binding pocket.

Reflecting on South African psychology: published research, ‘relevance’ and social issues

- Description: As South Africa prepared to host the 30th International Congress of Psychology in 2012, a call was made to reflect on the strengths of and challenges facing contemporary South African Psychology. This paper presents our response to our brief to focus on social issues by presenting the results of a situational analysis of South African Psychology over the last five years and comparing this corpus of data to a similar analysis reported in Macleod (2004). Articles appearing in the South African Journal of Psychology (SAJP) and abstracts in PsycINFO with the keyword ‘South Africa’ over a 5½ year period were analysed. The content of 243 SAJP articles and 1986 PsycINFO abstracts were analysed using the codes developed by Macleod (2004). Results indicate: an increase in the number of articles, a reduction in the percentage of articles using quantitative methodologies and ‘hard’ science theoretical frameworks (particularly in the SAJP), and an increase in qualitative, theoretical, and methodological papers, and papers using systems-oriented theory (particularly in the SAJP). Traditional topics of assessment, stress and psychopathology continue to dominate, with social issues such as housing, land reform, development programmes, water resources and socio-economic inequities being largely ignored. Most research continues to be conducted in Gauteng, KwaZulu/Natal and the Western Cape, predominantly with adult, urban-based, middle-class participants, sourced mainly from universities, hospitals or clinics and schools. Collaborations or comparisons with other African, Asian, South American and Middle East countries have decreased. While the analysis presented in this paper is limited by its exclusion of books, theses, research reports and monographs, it shows that in published research there are some positive trends and some disappointments. The limited number of social issues featuring in published research, the under-representation of certain sectors of the population as participants, and the decrease in collaboration with, or comparison to, countries from the global ‘South’ represent challenges that require systematic attention.

Responsive integrative treatment of PTSD and trauma related disorders : an expanded evidence-based model

- Description: In this article a practitioner oriented review of the literature on the treatment of post-traumatic stress disorder is used to construct a phase-based model that can serve as a basis for case formulation and treatment planning. Treatments shown to be efficacious in randomized controlled trials are listed and two discourses about them are contrasted. One calls for therapists to implement treatments scrupulously according to the manual, the other calls for flexibility and responsiveness to contextual understanding of the situation and personality of individual clients. Evidence for the centrality of the principles of this latter discourse for professional practice is summarized from work on case formulation, standards for therapist competence, and the concept of evidence-based practice. This provides the foundation for a model for treatment of PTSD, both simple and complex, that has five levels which represent increasing degrees of depth of clinical work. In accordance with the phased approach, conditions at one level need to be satisfied before proceeding to work on a deeper level. At each level specific areas of clinical focus are highlighted including risk management (at level 1), building the therapeutic alliance (at level 2) and trauma-focused work (at level 3). The model serves as a broad structured summary of accumulated clinical knowledge about PTSD and its treatment that provides an evidence-based foundation for assessment and treatment planning.

- Description: Eucalyptus grandis is a medicinal plant which has been indicated by Zulu traditional healer in the treatment of respira- tory tract infections, bronchial infections, asthma and cough. The investigation of the essential oil of this plant could help to verify the rationale behind the use of the plant as a cure for these illnesses. Essential oil was hydro-distilled from the fresh leaves and characterised for the chemical constituents and bioactivity. The main constituents of the oil of the E. grandis are α-Pinene (29.69%), p-Cymene (19.89%), 1,8-cineole (12.80%), α-Terpineol (6.48%), Borneol (3.48%) and D-Limonene (3.14%). The essential oil of E. grandis showed high scavenging of DPPH and ABTS radicals, and was active against 13 of the 16 organisms tested with the MIC ranging from 0.625 mg - 5.0 mg/ml; the MBC value ranged from 2.5 mg - 10 mg/ml. The essential oil also inhibited the growth of 7 of the 8 antibiotic resistant bacteria tested, with MIC ranging from 5 mg/ml - 10 mg/ml. The DNA extracted from the affected microorganisms did not show any dam- age however, there was an increase of released cytosolic LDH activity. We conclude that the antibacterial activity of the essential oil was exhibited through cell membrane damage rather than the damage of the DNA. It is apparent that the bioactivity of the essential oil of E. grandis plays an important role in the plants’ use in folk medicine for the treatment of respiratory tract illnesses.

The Evil of sluits : a re-assessment of soil erosion in the Karoo of South Africa as portrayed in century-old sources

- Description: Deep, linear gullies are a common feature of the present landscape of the Karoo of South Africa, where they were known locally in the early twentieth century as ‘sluits’. Recent research has shown that many of these features are now stable and are no longer significant sediment sources, although they are efficient connectors in the landscape. Because most of the gully networks predate the first aerial photographs, little is known in the scientific literature about the timing of their formation. One secondary source, however, throws interesting light on the origin of these features, and the early response by landowners to their rehabilitation. The Agricultural Journal of the Cape of Good Hope at the turn of the Twentieth Century carried a number of articles by farmers and agricultural officers concerning the "evil of sluits". The authors gave accounts of widespread incision of valley bottoms by deep, wide gullies. Many of these gullies had been in existence for some thirty years but apparently had formed within living memory. A number of attempts to prevent further erosion had been put in place at the time of writing. This paper presents a review of land degradation, specifically gully erosion, and rehabilitation recommendations as given by authors writing in this journal. It reflects on the findings in the context of assessing land degradation processes through the local knowledge portrayed in the journal.

- Description: From introduction: The Eastern Cape Gambling and Betting Board advertised a tender for research assessing and auditing the status of traditional horse racing in the Eastern Cape. The term ‘traditional horse racing’ (THR) is used for convenience but covers a range of horse racing events, not all of which are ‘traditional’. The term, within the research and this report, is used to denote all horse racing in the Eastern Cape which lies outside of the formal gambling horse racing industry which is localised to Port Elizabeth.

Towards an exceptional Undergraduate Personal Learning Experience: the Personal Librarian Programme, a pilot project at Rhodes University Library

- Description: This paper is a record of a unique intervention for enhancing the undergraduate learning experience at Rhodes University. It focuses on the establishment of the project, the experiences encountered and lessons learned thus far. In April 2013, a team of 13 librarians embarked on a Personal Librarian Pilot Project at the Rhodes University Library. The Personal Librarian Programme is primarily directed at undergraduate students at Rhodes University. In an attempt to bridge the information literacy skills gap that exists between Senior School and University in South Africa, the idea behind this programme is that each incoming first year student is assigned a Personal Librarian who will remain that individual’s contact in the library throughout his/her academic career at Rhodes University. The project came about as a result of research exploring the perceptions of both students and lecturers in the Commerce Faculty at Rhodes University with regard to Information Literacy practices and needs (Gontshi, 2011). The study revealed and recorded a shortcoming in the Information Literacy ability of students between Senior School Level and University Level. It became clear that new University students were not aware of the important link between their academic studies and the Library which in turn suggested the need to make Rhodes University librarians and the role that they play in the academic world more obvious to these new students (Gontshi, 2011). The Personal Librarian Programme was devised to fill this need. The Librarians involved in this programme include staff from all sections of the Library: circulation, faculty liaison and bibliographic/technical services. The training needs of staff who did not work directly with students were identified and the relevant training provided. The staff from circulation and bibliographic/technical services sections identified a need to advance their knowledge in the use of the library from a users’ perspective. The training focused on the following: “Brainstorming a research topic with a student”; “Identifying relevant databases to conduct a research topic” and “Conducting a search on relevant databases for the research topic” – this included different ways of devising an effective search technique. The training ensured a good foundation for these librarians to develop their confidence to work with users. The project, modeled on a similar programme at the Yale University Library in the United States of America, was also a direct result of Rhodes University Library’s involvement in the Carnegie Research Libraries Consortium (2009 – 2011) and the author’s ten-week internship in the United States, seven weeks of which were spent at Yale University.

- Description: Background: Drug-facilitated sexual assault (DFSA) has emerged as a distinct category of sexual victimization and precipitates posttraumatic stress disorder (PTSD). Few studies have examined the distinct psychological aspects of PTSD caused by DFSA. Gauntlett-Gilbert, Keegan and Petrak (2004) represent a notable exception and draw on cases, from their clinical experience, treated using Ehlers and Clarks’ (2000) cognitive therapy (CT). Aims: This paper aims to further develop and refine clinical knowledge on CT for PTSD arising from DFSA and advance the findings of Gauntlett-Gilbert et al. (2004). Method: Systematic case based research was used to investigate the applicability of CT for PTSD related to DFSA. Three survivors were treated with CT within the South African context. Results: The case series corroborated existing findings but also documented the presence of somatic and visual intrusions among survivors with partial or complete amnesia for rape and illustrated the utility of imagery interventions in targeting intrusions. The study highlighted the role of physical paralysis in DFSA in compounding helplessness/powerlessness and the necessity of enhancing physical agency and building social support. Conclusion: Distinctive aspects of PTSD related to DFSA can be effectively treated by adapting CT to suit this population group.

- Description: From Introduction: Drug facilitated sexual assault (DFSA) -- on victims who are too intoxicated to be aware of their surroundings or exercise any control of the situation -- has emerged as a distinct category of sexual victimisation. DFSA has been identified as a significant public health concern, particularly among college students, with the majority of victims being women (McCauley, Ruggiero, Resnick, & Kilpatrick, 2010; Zinzow, Resnick, McCauley, Amstadter, Ruggiero, & Kilpatrick, 2010). Exact rates remain uncertain due to significant under-reporting (Du Mont, Macdonald, Rotbard, Asslanni, & Bainbridge, 2010; Lawyer, Resnick, Bakanic, Burkett, & Kilpatrick, 2010). Opportunistic DFSA, also called incapacitated rape (Lawyer et al., 2010; Zinzow at al., 2010), is the most common form and refers to assaults on women who have voluntarily consumed an excessive amount of alcohol (Lovett & Horvath, 2009). In proactive DFSA (called drug facilitated rape by Lawyer et al., 2010 and drug-alcohol facilitated rape by Zinzow et al., 2010), perpetrators deliberately incapacitate victims by plying them with alcohol or covertly administering an incapacitating drug such as Flunitrazepam (Rohypnol) or Gamma-hydroxybutyrate (GHB) to victims with the intention of sexually assaulting them (Hall & Moore, 2008).

- Description: Few clinical studies have examined victimisation in the lives of lesbian women in South Africa and whether there are distinct implications for psychological treatment. This paper presents the assessment and treatment of a lesbian-identified South African survivor of childhood sexual abuse who, as an adult, was raped and later gang raped. Her victimisation in adulthood represented ‘corrective rape’ motivated by the prejudiced assumption that the sexuality of lesbian women is pathological and should be ‘corrected’ through rape. This paper lends insights into the role of heterosexism in shaping vulnerability to victimisation and the process of recovery. It provides recommendations for work with sexual minority clients and highlights the implications when there is an absence of safety and support in the external environment.

When veiled silences speak: reflexivity, trouble and repair as methodological tools for interpreting the unspoken in discourse-based data

- Description: Researchers who have attempted to make sense of silence in data have generally considered literal silences or such things as laughter. We consider the analysis of veiled silences where participants speak, but their speaking serves as ‘noise’ that ‘veils’, or masks, their inability or unwillingness to talk about a (potentially sensitive) topic. Extending Lisa Mazzei’s ‘problematic of silence’ by using our performativity-performance analytical method, we propose the purposeful use of ‘unusual conversational moves’, the deployment of researcher reflexivity, and the analysis of trouble and repair as methods to expose taken-for-granted normative frameworks in veiled silences. We illustrate the potential of these research practices through reference to our study on men’s involvement in reproductive decision-making, in which participants demonstrated an inability to engage with the topic. The veiled silence that this produced, together with what was said, pointed to the operation of procreative heteronormativity.

- Description: South Africa does not have a particularly proud history. Marred by the politics of separate but (un)equal treatment of its people, the country's past political system has had a damaging effect in all spheres, but specifically on that of the family. In the context of relationships, it is fair to say that the apartheid system was replicated in family law, with the Western 'white' monogamous marriage receiving the state's stamp of approval - leaving other relationships (customary, Muslim, homosexual, cohabiting etc) largely out in the cold.

“It’s like uprooting trees”: responsive treatment for a case of complex post-traumatic stress disorder following multiple rapes

- Description: This systematic case study documents 27 sessions of assessment and treatment with cognitive therapy of Bongi (23)who presented with major depression, posttraumatic stress disorder and borderline traits. Bongi had been raised in a punitive environment, had been raped three times, the first time at age 9, and had been in a series of abusive relationships. The treatment illustrates the importance of therapist responsiveness in addressing this kind of complex presentation, the importance of drawing on case formulation to guide the course of treatment and the range of different interventions that need to be incorporated into an integrative treatment of a complex case. Self-report measures of depression, anxiety and posttraumatic stress indicators provided evidence that the therapy contributed to positive changes and the qualitative therapy narrative gives details of the nature of some of those changes. Although treatment was not complete when Bongi moved away, Bongi herself judged that the therapy had been a valuable experience which had resulted in her feeling more alive, more confident, and better able to take care of herself.
