Perceived Motivating Factors towards a Positive Working Environment in Rural Hospital at Vhembe District in the Limpopo Province

One of the Millennium Development Goals (MDGs) is to improve maternal health with the target of reducing maternal mortality by three-quarters between 1990–2015. The rendering of quality patient care requires the whole healthcare system to be functional with well-trained, motivated staff, adequate services, equipment and skilled competent leadership. However, work environment in rural hospitals is poorly resourced, thus leading to many nurses becoming de-motivated. This paper describes the factors that the nurses would like to see in their working environment which could improve quality patient care in rural hospitals. An appreciative inquiry qualitative, exploratory, descriptive research design was used. Data were collected through focus group interviews whereby thirty six participants were interviewed. The researcher used the open coding technique to analyse data. The findings revealed that nurses are motivated by both extrinsic and intrinsic factors in their working environment.Department of HE and Training approved lis

Genetics knowledge of advanced midwifery learners : educators' perceptions

Healthcare professionals require adequate knowledge of genetics to be able to assess, diagnose, manage and prevent in good time genetic-related diseases. Healthcare professionals empowered in this field are able to differentiate at an early stage between genetic and genomic components of diseases. Advanced midwifery learners are trained to provide specialist holistic care that includes genetics upon course completion. Their genetic knowledge is crucial for them to provide genetic services in clinical- and in primary health care (PHC) settings. This study explores perceptions of advanced midwifery educators regarding genetics knowledge of their learners. A qualitative, explorative and descriptive design was employed. A total of 19 participants took part in this study. Data were collected through focus group discussions, individual face-to-face and telephone interviews. Thematic analysis was used for data analysis. Genetic knowledge emerged as a major theme under which genetic concepts, genetic history taking, common genetic disorders, genetic counselling, identification and management of genetic disorders were identified as sub-themes. At present, genetics education is addressed at the discretion of the individual advanced midwifery educators during training. This random kind of teaching is attributed to the lack of a curriculum framework that standardises genetics education at nursing education institutions (NEIs) in South Africa. The importance of genetics education is underrated in advanced midwifery courses, contributing to learners lacking adequate knowledge of genetics. Advanced midwifery learners need a sufficient knowledge of genetics to provide holistic care in clinical and PHC settings upon course completion.UNEDSAhttp://www.ajol.info/journal_index.php?jid=153&ab=ajpherd2016-10-31hb201

Reflections on the concomitants of the restrictive visitation policy during the COVID-19 pandemic : an ubuntu perspective

Caregiving is a prominent concept in the Ubuntu philosophy, and caring and visitation of the sick is regarded as an example of Ubuntu. The restrictive visitation policy adopted in the hospitals during the coronavirus disease 2019 (COVID-19) pandemic affected the exhibition of this concept among patients, nurses, and families. The narrative inquiry was used to explore the reflections of the participants on the impact caused by the nonvisitation policy experienced during the first and second waves of the COVID-19 pandemic in South Africa. The narrative inquiry approach allowed the participants to tell their story as it is unique to them. The study used purposive sampling technique to select five participants for the webinar. Three themes emerged from the narrated stories which are 1) moral anguish of the caregivers; 2) mental health instability, and 3) erosion of trust in health care practitioners (HCPs). The non-visitation hospital policy was intended to reduce the danger of spreading COVID-19 within and outside the hospital; however, the care provided was devoid of the values of Ubuntu such as mutual respect, relational, responsibility, reciprocity, and interconnectedness. In retrospect, a case-by-case application of the policy would reduce the non-desirable effect of the policy on the patients, nurses, and patients’ family members.https://www.frontiersin.org/journals/sociologydm2022Nursing Scienc

Haulout site selection by southern elephant seals at Marion Island

Using data from an ongoing mark-resight programme at Marion Island, we tested empirically whether southern elephant seals prefer certain terrestrial sites to others during the breeding, moulting and winter haulouts, and whether the pattern of site use is the same for different age and sex groups. Southern elephant seals preferred some sites, while discriminating against other sites, with different age and sex classes using different sites for certain haulout events. Wintering young animals did not show strong site selection. Some popular sites were used for all haulouts by all age and sex groups, and apparently have all the requirements of a good site for terrestrial haulout by southern elephant seals. Site selection becomes more apparent with age, suggesting the role of haulout experience in site selection

Rapid compact jet quenching in the Galactic black hole candidate X-ray binary MAXI J1535-571

We present results from six epochs of quasi-simultaneous radio, (sub-)millimetre, infrared, optical, and X-ray observations of the black hole X-ray binary MAXI J1535-571. These observations show that as the source transitioned through the hard-intermediate X-ray state towards the soft-intermediate X-ray state, the jet underwent dramatic and rapid changes. We observed the frequency of the jet spectral break, which corresponds to the most compact region in the jet where particle acceleration begins (higher frequencies indicate closer to the black hole), evolves from the infrared band into the radio band (decreasing by approximate to 3 orders of magnitude) in less than a day. During one observational epoch, we found evidence of the jet spectral break evolving in frequency through the radio band. Estimating the magnetic field and size of the particle acceleration region shows that the rapid fading of the high-energy jet emission was not consistent with radiative cooling; instead, the particle acceleration region seems to be moving away from the black hole on approximately dynamical time-scales. This result suggests that the compact jet quenching is not caused by local changes to the particle acceleration, rather we are observing the acceleration region of the jet travelling away from the black hole with the jet flow. Spectral analysis of the X-ray emission shows a gradual softening in the few days before the dramatic jet changes, followed by a more rapid softening similar to 1-2 d after the onset of the jet quenching

Ordered magnetic fields around the 3C 84 central black hole

Context. 3C 84 is a nearby radio source with a complex total intensity structure, showing linear polarisation and spectral patterns. A detailed investigation of the central engine region necessitates the use of very-long-baseline interferometry (VLBI) above the hitherto available maximum frequency of 86 GHz.Aims. Using ultrahigh resolution VLBI observations at the currently highest available frequency of 228 GHz, we aim to perform a direct detection of compact structures and understand the physical conditions in the compact region of 3C 84.Methods. We used Event Horizon Telescope (EHT) 228 GHz observations and, given the limited (u; v)-coverage, applied geometric model fitting to the data. Furthermore, we employed quasi-simultaneously observed, ancillary multi-frequency VLBI data for the source in order to carry out a comprehensive analysis of the core structure.Results. We report the detection of a highly ordered, strong magnetic field around the central, supermassive black hole of 3C 84. The brightness temperature analysis suggests that the system is in equipartition. We also determined a turnover frequency of gamma(m) = (113 +/- 4) GHz, a corresponding synchrotron self-absorbed magnetic field of B-SSA = (2.9 +/- 1.6) G, and an equipartition magnetic field of B-eq = (5.2 +/- 0.6) G. Three components are resolved with the highest fractional polarisation detected for this object (m(net) = (17.0 +/- 3.9)%). The positions of the components are compatible with those seen in low-frequency VLBI observations since 2017-2018. We report a steeply negative slope of the spectrum at 228 GHz. We used these findings to test existing models of jet formation, propagation, and Faraday rotation in 3C 84.Conclusions. The findings of our investigation into di fferent flow geometries and black hole spins support an advection-dominated accretion flow in a magnetically arrested state around a rapidly rotating supermassive black hole as a model of the jet-launching system in the core of 3C 84. However, systematic uncertainties due to the limited (u, v)-coverage, however, cannot be ignored. Our upcoming work using new EHT data, which offer full imaging capabilities, will shed more light on the compact region of 3C 84

First M87 Event Horizon Telescope Results. IX. Detection of Near-horizon Circular Polarization

Event Horizon Telescope (EHT) observations have revealed a bright ring of emission around the supermassive black hole at the center of the M87 galaxy. EHT images in linear polarization have further identified a coherent spiral pattern around the black hole, produced from ordered magnetic fields threading the emitting plasma. Here we present the first analysis of circular polarization using EHT data, acquired in 2017, which can potentially provide additional insights into the magnetic fields and plasma composition near the black hole. Interferometric closure quantities provide convincing evidence for the presence of circularly polarized emission on event-horizon scales. We produce images of the circular polarization using both traditional and newly developed methods. All methods find a moderate level of resolved circular polarization across the image (〈∣v∣〉 < 3.7%), consistent with the low image-integrated circular polarization fraction measured by the Atacama Large Millimeter/submillimeter Array (∣v int∣ < 1%). Despite this broad agreement, the methods show substantial variation in the morphology of the circularly polarized emission, indicating that our conclusions are strongly dependent on the imaging assumptions because of the limited baseline coverage, uncertain telescope gain calibration, and weakly polarized signal. We include this upper limit in an updated comparison to general relativistic magnetohydrodynamic simulation models. This analysis reinforces the previously reported preference for magnetically arrested accretion flow models. We find that most simulations naturally produce a low level of circular polarization consistent with our upper limit and that Faraday conversion is likely the dominant production mechanism for circular polarization at 230 GHz in M87*
