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

Utilising the Healy and Jenkin’s Research Teaching and Curriculum Design Nexus to transform undergraduate nursing research communities of practice

In science, research is known to be a diligent systematic inquiry into nature and society or both. It assists in validating and refining existing knowledge and generating new knowledge. Lecturers and scholars have embraced the integration of evidence-based practice into the nursing education curriculum in numerous ways. Although the learning competencies necessary for research competencies amongst undergraduate nurses include an understanding of the basic concepts and processes of research methods, it does not adequately support student preparedness for the attainment of postgraduate research competencies. The design of this study adopted a qualitative, exploratory and descriptive course of enquiry that explored current pedagogical research practices amongst lecturers and supervisors. A case study approach utilising, specifically, a cross-case analysis helped provide a clear picture of institutional pedagogical practices related to the topic of inquiry and its implementation thereof. The cases from approved local, national and international higher education institutions formed the setting for the study. Lecturers facilitating and supervising undergraduate and postgraduate research studies comprised the target population of a purposive sampling selection. In this study, the authors utilised the Healey and Jenkins Teaching Nexus to show that the research engagement of students and nursing research communities of practice can be strengthened if embraced by sound pedagogical practices. The Nexus outlines four concepts that guide the pedagogical practice of the research module that promotes undergraduate students as researchers. The authors of this article concluded that it was necessary to engage students as producers and not merely as consumers of knowledge. In this study, the researchers also utilised the Nexus to show students’ engagement in fostering different teaching approaches to research knowledge acquisition

Gastro-oesophageal reflux - an overview

Gastro-oesophageal reflux disease (GORD) presents with patients experiencing discomfort due to acid-containing stomach contents persistently being refluxed into the oesophagus. This condition can lead to serious complications if left untreated. The two chief complaints of GORD are heartburn and regurgitation. The management of GORD is wide and varied and includes antacids, H2-antagonists, alginates, pro-kinetics, or proton pump inhibitors. GORD is known to cause economic and social burdens, thus appropriate management is vital to improving a patient’s quality of life.http://www.sapj.co.za/index.php/sapjam2023Pharmacolog

Perceptions and knowledge about the acquired immunodeficiency syndrome among students in university residences

Using an anonymous questionnaire to obtain baseline data on sexual behaviour and knowledge of the acquired immunodeficiency syndrome (AIDS) among students in university residences, the following information was obtained: Knowledge of AIDS was found to be high, although misconceptions regarding transmission of the virus were prevalent. Mosquito bites (15%) and the donating of blood (31%) were incorrectly identified as methods of transmission of the virus. Deep kissing was recognised by only 27% of the students as a possible method of transmission while 22% and 13% of the students, respectively, failed to identify the sharing of razor blades and blood transfusions as possible means of contracting HIV infection. The students' knowledge had not greatly affected sexual behaviour. Two-thirds of the respondents had previously had sexual contact; 38% .were sexually active at the time of the study, and of these 74% had engaged in unprotected intercourse with casual partners in the previous 6 months. There was a negative attitude towards condom use and over 80% of sexually active students did not perceive themselves to be at risk of contracting AIDS. Campus Health (82%), State health services (51%), and public advertisements (60%) were preferred sources of AIDS information. Newspapers/ magazines (80%) and leaflets (69%) were identified as the preferred media. In reality, significantly fewer students obtained their information from Campus Health (15%; P < 0,05), State health services (19%; P < 0,05) and leaflets (44%; P < 0,05). It can be concluded that education programmes should be developed by credible organisations to ensure that an awareness of AIDS results in appropriate sexual behaviour

Revival of the magnetar PSR J1622-4950: observations with MeerKAT, Parkes, XMM-Newton, Swift, Chandra, and NuSTAR

New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622-4950 indicate that the magnetar, in a quiescent state since at least early 2015, reactivated between 2017 March 19 and April 5. The radio flux density, while variable, is approximately 100x larger than during its dormant state. The X-ray flux one month after reactivation was at least 800x larger than during quiescence, and has been decaying exponentially on a 111+/-19 day timescale. This high-flux state, together with a radio-derived rotational ephemeris, enabled for the first time the detection of X-ray pulsations for this magnetar. At 5%, the 0.3-6 keV pulsed fraction is comparable to the smallest observed for magnetars. The overall pulsar geometry inferred from polarized radio emission appears to be broadly consistent with that determined 6-8 years earlier. However, rotating vector model fits suggest that we are now seeing radio emission from a different location in the magnetosphere than previously. This indicates a novel way in which radio emission from magnetars can differ from that of ordinary pulsars. The torque on the neutron star is varying rapidly and unsteadily, as is common for magnetars following outburst, having changed by a factor of 7 within six months of reactivation.Comment: Published in ApJ (2018 April 5); 13 pages, 4 figure

Age of Child, More than HPV Type, Is Associated with Clinical Course in Recurrent Respiratory Papillomatosis

Background: RRP is a devastating disease in which papillomas in the airway cause hoarseness and breathing difficulty. The disease is caused by human papillomavirus (HPV), 6 or 11 and is very variable. Patients undergo multiple surgeries to maintain a patent airway and in order to communicate vocally. Several small studies have been published in which most have noted that HPV 11 is associated with a more aggressive course. Methodology/Principal Findings: Papilloma biopsies were taken from patients undergoing surgical treatment of RRP and were subjected to HPV typing. 118 patients with juvenile-onset RRP with a least 1 year of clinical data and infected with a single HPV type were analyzed. HPV 11 was encountered in 40% of the patients. By our definition, most of the patients in the sample (81%) had run an aggressive course. The odds of a patient with HPV 11 running an aggressive course were 3.9 times higher that that of patients with HPV 6 (Fisher's exact p=0.017). However, clinical course was more closely associated with age of the patient (at diagnosis and at the time of the current surgery) than with HPV type. Patients with HPV 11 were diagnosed at a younger age (2.4y) than were those with HPV 6 (3.4y) (p=0.014). Both by multiple linear regression and by multiple logistics regression HPV type was only weakly associated with metrics of disease course when simultaneously accounting for age. Conclusions/Significance Abstract: The course of RRP is variable and a quarter of the variability can be accounted for by the age of the patient. HPV 11 is more closely associated with a younger age at diagnosis than it is associated with an aggressive clinical course. These data suggest that there are factors other than HPV type and age of the patient that determine disease course. © 2008 Buchinsky et al

Glandular Odontogenic Cyst: Report of Two Cases and Review of Literature

Glandular odontogenic cyst (GOC) is an uncommon jaw bone cyst of odontogenic origin described in 1987 by Gardner et al. It is a cyst having an unpredictable and potentially aggressive behaviour. It also has the propensity to grow to a large size and tendency to recur with only 111 cases having been reported thus far. The first case occurred in a 42-year-old female and presented as a localized swelling extending from 19 to 29 regions. There was a history of traumatic injury at the site. There was evidence of bicortical expansion and radiographs revealed a multilocular radiolucency. The second case occurred in a 21-year-old male, as a large swelling in the mandible and radiograph revealed radiolucency in the region. On histopathological examination, these lesions were diagnosed as GOC. It was concluded that, two cases submitted by us correlate with the existing literature that GOC’s affect more commonly in the middle age group, having predilection for mandible and that trauma could be a precipitating factor for its occurrence. The increased recurrence rates can be due to its intrinsic biological behavior, multilocularity of the cyst, and incomplete removal of the lining following conservative treatment
