A selected history of South African inflation perceptions: The question matters

This paper provides a selected historical overview of inflation perception surveys undertaken in South Africa between 2006 and 2010 with a view to assessing the nature of the link between inflation perceptions and inflation expectations in the latest 2012 survey. These surveys are undertaken to assess the perceptions of respondents on the degree in which historic inflation figures reflect perceptions of actual inflation, and to find some link to inflation expectations. All the earlier pilot studies on inflation perceptions and the representative samples undertaken between 2006 and 2010 (in total six pilot studies, three representative samples and one survey among central bank employees) failed to show any link between inflation perceptions and inflation expectations. These findings cast some doubt on the premise that a policy of inflation targeting anchors inflation expectations in the current rate of inflation and therefore in the announced inflation target policy rate. In response to the earlier survey results, the question on inflation perceptions was put in different ways to respondents in the most-recent (2012) inflation perception survey to retest the hypothesis that inflation perceptions and inflation expectations are linked. The findings of this survey are analysed in this paper. These findings show a possible link to inflation expectations, and will be the subject of further research. The conclusion on the assessment of inflation perceptions is that the question matters.KIM201

Inflation perceptions and inflation expectation in South Africa: trends, determinants and comparisons (2006–2010)

This paper reports the results of a multinomial analysis of inflation perceptions and inflation expectations in South Africa. Inflation perceptions surveys among South African individuals have been undertaken since 2006. The introduction of these surveys followed on domestic inflation expectation surveys conducted in 2000, and the use of inflation perceptions surveys internationally. Domestic inflation perceptions surveys among individuals are a private initiative undertaken biennially, while domestic inflation expectation surveys among individuals are funded by the South African Reserve Bank and are undertaken quarterly. By comparing the results of domestic inflation perceptions surveys and inflation expectation surveys undertaken since 2006, this paper establishes common characteristics that impact on the formulation of inflation perceptions and inflation expectations. It supplements earlier research that focused only on the results of the 2006 and 2008 perceptions survey results. With the completion of the third biennial inflation perceptions survey in 2010, more data sets are available for the purposes of comparison. Furthermore, the questions on inflation perceptions were expanded in the third survey. Although this provides for a broader basis of analysis between inflation perceptions surveys and inflation expectation surveys, further periodic inflation perceptions survey data will be required to test whether current inflation figures determine and anchor inflation expectations.Key words: inflation, inflation perceptions, inflation expectations, inflation perceptions, inflation surveys, multinomial analysi

The effect of a 6-month cardiac rehabilitation programme on serum lipoproteins and apoproteins A1 and B and lipoprotein a

One hundred and forty-two cardiac rehabilitation patients were followed up over a p.eriod of 6 months and the percentage change over time was recorded for various lipid fractions including apoprotein AI (apo AI), apoprotein B (apo B) and lipoprotein a (Lp(a)). Data were analysed to see if improvement in peak oxygen consumption (V2) or changes in body weight were related to any of the above. A significant percentage change was found for peak Vo2, ventilatory threshold, highdensity lipoprotein cholesterol (HDLC) and triglyceride levels, total cholesterol (TC)/HDL ratio, apo AI, apo A/apo B ratio and Lp(a). Multiple regression analysis showed that alterations in the lipid fractions were not related to changes in physical fitness except in the case of TC levels which dropped independently of other measures. On multivariate analysis, Lp(a) correlated positively with both the Broca index and the use of drugs ofthe fibrate series.S Afr Med J1993; 83: 315-31

The areca nut chewing habit and oral squamous cell carcinoma in South African Indians

A retrospective study (1983 - 1989) of oral squamous carcinomas and concomitant oral habits was undertaken in South African Indians from Natal. Information came from hospital records and interviews with patients, famlilies and friends. There were 143 oral squamous carcinomas; these occurred in a ratio of 1:1,6 for men and women respectively. Squamous carcinomas of the cheek (buccal mucosa, alveolar sulcus and gingiva) occurred most frequently, especially in women (57/89 - 64%), while in men tongue cancer predominated (22/54 - 41-%). Ninety-three per cent of women (83/87) and 17% of men (9/54) habitually chewed the areca nut. Thirty-nine of 57 women (68%) with cheek cancer and 21/25 (84%) with tongue cancer only chewed the nut (no tobacco, snuff or smoking). Analyses confinned an association between nut chewing and cheek cancer. The odds ratio (OR) for oral cancer in women 25 years and older who only chewed the nut was 43,9 and the attributable risk (AR) 0,89 (89%). With tobacco the OR increases to 47,42 and the AR to 0,91 (91%). The data showed that the areca nut habit with or without tobacco use is important in the development of oral squamous carcinoma. Elimination of this habit can reduce the risk in these women substantially (89 - 91%) if all other factors remain the same

Learning to belong: Navigating liminal spaces between disciplinary and teaching identities

The continuous professional learning of academics as university teachers is a national imperative in South Africa. At our university, a Postgraduate Diploma in Education (Higher Education) was introduced in 2015 with the aim to professionalise university teaching through a formal qualification. Students (i.e., candidates) must transition in two ways: firstly, from being disciplinary specialists to being students again; and secondly, into the community of scholarly teaching in higher education. This article examines the liminality experienced by candidates as they navigate the programme and learn to belong to a new scholarly teaching community. Drawing on empirical data collected from graduates and programme coordinators, the authors track candidates’ shifting identities and showcase how, though initially turbulent and unsettling, the process of learning to belong to a new teaching identity can be rewarding and enriching. The authors conclude by discussing the conditions required to enable candidates to acquire a strong university-teacher identity

From pandemic disruption to post-pandemic transformation: New possibilities for teaching in South African higher education

The COVID-19 pandemic has had previously unimaginable and far-reaching effects on higher education globally (Baker et al. 2022; Cranfield et al. 2021; Kara 2021; Le Grange 2020). On top of the widespread loss felt by students and teachers across the world, we have had to make rapid changes to previously taken-for-granted ways of doing, being, learning and teaching (Baker et al. 2022; Cranfield et al. 2021). Emergency Remote Teaching and Learning (ERTL) brought constraints and opportunities, challenges and innovations. This article gives form to the statement: “there is an opportunity in the moment for genuine equity-focused innovation in policy-making, provision and pedagogy” (Czerniewicz et al. 2020). We use a theoretical framework of structure, culture and agency through which to view possibilities for transformation of pedagogy, and a form of semi-autoethnography as methodology. Two lecturers, one in the Humanities (Education) and one in the Life Sciences, wrote extended narratives of their experiences of ERTL and the other authors then posed a series of questions to the story authors, which elicited a set of analytic descriptions and explanations. Through iterations of this analysis, we identified two important themes: attending to students’ socio-emotional needs and developing students’ engagement, self-regulation and reflexivity. The analysis identifies key opportunities and challenges that these required and how they were addressed by the lecturers concerned. Based on the analysis and drawing on Case’s (2015b) argument for an expanded sense of agency for students, we argue that the lecture is a key structural and cultural element of the university space that was disrupted during the pandemic and can be transformed going forward. We thus argue for decentering the lecture. Furthermore, we argue that care and concern for students has not been a primary cultural element of teaching and learning in higher education, for structural reasons, and that it should be an integral part of pedagogies going forward

A dedicated vascular access clinic for children on haemodialysis: Two years' experience

BACKGROUND: Arteriovenous fistula (AVF) formation for long-term haemodialysis in children is a niche discipline with little data for guidance. We developed a dedicated Vascular Access Clinic that is run jointly by a transplant surgeon, paediatric nephrologist, dialysis nurse and a clinical vascular scientist specialised in vascular sonography for the assessment and surveillance of AVFs. We report the experience and 2-year outcomes of this clinic. METHODS: Twelve new AVFs were formed and 11 existing AVFs were followed up for 2 years. All children were assessed by clinical and ultrasound examination. RESULTS: During the study period 12 brachiocephalic, nine basilic vein transpositions and two radiocephalic AVFs were followed up. The median age (interquartile range) and weight of those children undergoing new AVF creation were 9.4 (interquartile 3-17) years and 26.9 (14-67) kg, respectively. Pre-operative ultrasound vascular mapping showed maximum median vein and artery diameters of 3.0 (2-5) and 2.7 (2.0-5.3) mm, respectively. Maturation scans 6 weeks after AVF formation showed a median flow of 1277 (432-2880) ml/min. Primary maturation rate was 83 % (10/12). Assisted maturation was 100 %, with two patients requiring a single angioplasty. For the 11 children with an existing AVF the maximum median vein diameter was 14.0 (8.0-26.0) mm, and the median flow rate was 1781 (800-2971) ml/min at a median of 153 weeks after AVF formation. Twenty-two AVFs were used successfully for dialysis, a median kt/V of 1.97 (1.8-2.9), and urea reduction ratio of 80.7 % (79.3-86 %) was observed. One child was transplanted before the AVF was used. CONCLUSIONS: A multidisciplinary vascular clinic incorporating ultrasound assessment is key to maintaining young children on chronic haemodialysis via an AVF

The Johannesburg cardiac rehabilitation programme

Cardiac rehabilitation has become a generally accepted mode of treatment for patients suffering from coronary artery disease. The Johannesburg cardiac rehabilitation programme has started in 1982 and has rapidly grown to become one of the largest programmes in southern Africa. This paper describes the 387 patients admitted to the unit l;Ietween June 1986 and July 1988 and evaluates the effects of a combined exercise training and lifestyle modification programme. The mean age on admission was 55 years for males and 58 years for females. Most patients were from social classes I and 11. Myocardial infarction, coronary artery bypass graft and a combination of both were the most common reasons for admission (35,4%. 23% and 21,2% respectively). On admission 72,9% of patients were smokers, 26,3% had hypertension and 34,3% had hypercholesterolaemia. A 50% drop-out rate within 12 months of starting the programme was noted. An increase in peak oxygen uptake, weight and skinfold thickness reduction, and improvement in the lipogram were seen after 6 months in patients who complied well with the programme. Cardiac rehabilitation is a secondary preventive strategy that can complement traditional medical and surgical therapies

Smartphone-based remote monitoring for chronic heart failure: mixed methods analysis of user experience from patient and nurse perspectives

BACKGROUND: Community-based management by heart failure specialist nurses (HFSNs) is key to improving self-care in heart failure with reduced ejection fraction. Remote monitoring (RM) can aid nurse-led management, but in the literature, user feedback evaluation is skewed in favor of the patient rather than nursing user experience. Furthermore, the ways in which different groups use the same RM platform at the same time are rarely directly compared in the literature. We present a balanced semantic analysis of user feedback from patient and nurse perspectives of Luscii, a smartphone-based RM strategy combining self-measurement of vital signs, instant messaging, and e-learning. OBJECTIVE: This study aims to (1) evaluate how patients and nurses use this type of RM (usage type), (2) evaluate patients' and nurses' user feedback on this type of RM (user experience), and (3) directly compare the usage type and user experience of patients and nurses using the same type of RM platform at the same time. METHODS: We performed a retrospective usage type and user experience evaluation of the RM platform from the perspective of both patients with heart failure with reduced ejection fraction and the HFSNs using the platform to manage them. We conducted semantic analysis of written patient feedback provided via the platform and a focus group of 6 HFSNs. Additionally, as an indirect measure of tablet adherence, self-measured vital signs (blood pressure, heart rate, and body mass) were extracted from the RM platform at onboarding and 3 months later. Paired 2-tailed t tests were used to evaluate differences between mean scores across the 2 timepoints. RESULTS: A total of 79 patients (mean age 62 years; 35%, 28/79 female) were included. Semantic analysis of usage type revealed extensive, bidirectional information exchange between patients and HFSNs using the platform. Semantic analysis of user experience demonstrates a range of positive and negative perspectives. Positive impacts included increased patient engagement, convenience for both user groups, and continuity of care. Negative impacts included information overload for patients and increased workload for nurses. After the patients used the platform for 3 months, they showed significant reductions in heart rate (P=.004) and blood pressure (P=.008) but not body mass (P=.97) compared with onboarding. CONCLUSIONS: Smartphone-based RM with messaging and e-learning facilitates bilateral information sharing between patients and nurses on a range of topics. Patient and nurse user experience is largely positive and symmetrical, but there are possible negative impacts on patient attention and nurse workload. We recommend RM providers involve patient and nurse users in platform development, including recognition of RM usage in nursing job plans
