Health seeking behaviour and challenges in utilising health facilities in Wakiso district, Uganda

Background: The health seeking behaviour of a community determines how they use health services. Utilisation of health facilities can be influenced by the cost of services, distance to health facilities, cultural beliefs, level of education and health facility inadequacies such as stock-out of drugs.Objectives: To assess the health seeking practices and challenges in utilising health facilities in a rural community in Wakiso district, Uganda.Methods: The study was a cross sectional survey that used a structured questionnaire to collect quantitative data among 234 participants. The sample size was obtained using the formula by Leslie Kish.Results: While 89% of the participants were aware that mobile clinics existed in their community, only 28% had received such services in the past month. The majority of participants (84%) did not know whether community health workers existed in their community. The participants’ health seeking behaviour the last time they were sick was associated with age (p = 0.028) and occupation (p = 0.009). The most significant challenges in utilising health services were regular stock-out of drugs, high cost of services and long distance to health facilities.Conclusions: There is potential to increase access to health care in rural areas by increasing the frequency of mobile clinic services and strengthening the community health worker strategy.Key words: Health seeking behaviour, Rural community, Health facilities, Challenges, Ugand

Reducing child undernutrition through dietary diversification, reduced aflatoxin exposure, and improved hygiene practices: the immediate impacts in central Tanzania

Open Access Article; Published online: 28 Nov 2019The study aimed to quantify the immediate effects of dietary diversification, food safety, and hygiene interventions on child undernutrition in four rural villages in Kongwa district of central Tanzania. One hundred mothers with their children of less than 24 months old were recruited for this study. The difference-in-difference (DID) method was used to assess the effects of intensive intervention through a learning-by-doing process on the topic of aflatoxin free diversified food utilization and improved hygiene practices. Periodic anthropometric measurements were conducted on the 0th, 7th, 14th, and 21st days, and DID estimator showed the significant and positive average marginal effects of the intervention on Z-Scores being 0.459, 0.252, and 0.493 for wasting, stunting, and underweight, respectively. Notably, at the end of the study, the mean aflatoxin M1 level in urine samples decreased by 64% in the intervention group, while it decreased by 11% in the control group. The study provides quantitative evidence on intensive 21-day training for mothers incorporating integrated technologies yielded positive impacts on their children’s nutritional outcomes

Magnetic flux plays an important role during a BHXRB outburst in radiative 2T GRMHD simulations

Black hole (BH) X-ray binaries cycle through different spectral states of accretion over the course of months to years. Although fluctuations in the BH mass accretion rate are generally recognized as the most important component of state transitions, it is becoming increasingly evident that magnetic fields play a similarly important role. In this article, we present the first radiative two-temperature (2T) general relativistic magnetohydrodynamics (GRMHD) simulations in which an accretion disk transitions from a quiescent state at an accretion rate of $\dot{M} \sim 10^{-10} \dot{M}_{\rm Edd}$ to a hard-intermediate state at an accretion rate of $\dot{M} \sim 10^{-2} \dot{M}_{\rm Edd}$. This huge parameter space in mass accretion rate is bridged by artificially rescaling the gas density scale of the simulations. We present two jetted BH models with varying degrees of magnetic flux saturation. We demonstrate that in `Standard and Normal Evolution' models, which are unsaturated with magnetic flux, the hot torus collapses into a thin and cold accretion disk when $\dot{M} \gtrsim 5\times 10^{-3} \dot{M}_{\rm Edd}$. On the other hand, in `Magnetically Arrested Disk' models, which are fully saturated with vertical magnetic flux, the plasma remains mostly hot with substructures that condense into cold clumps of gas when $\dot{M} \gtrsim 1 \times 10^{-2} \dot{M}_{\rm Edd}$. This suggests that the spectral signatures observed during state transitions are closely tied to the level of magnetic flux saturation.Comment: 8 pages, 5 figures, accompanying animations included in YouTube playlist: https://www.youtube.com/playlist?list=PLDO1oeU33Gwm1Thyw0iHC14BbvBWaG5c

Constraints on black-hole charges with the 2017 EHT observations of M87*

Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M87* shadow size to infer constraints on the physical charges of a large variety of nonrotating or rotating black holes. For example, we show that the quality of the measurements is already sufficient to rule out that M87* is a highly charged dilaton black hole. Similarly, when considering black holes with two physical and independent charges, we are able to exclude considerable regions of the space of parameters for the doubly-charged dilaton and the Sen black holes

A search for pulsars around Sgr A* in the first Event Horizon Telescope data set

In 2017 the Event Horizon Telescope (EHT) observed the supermassive black hole at the center of the Milky Way, Sagittarius A* (Sgr A*), at a frequency of 228.1 GHz (λ = 1.3 mm). The fundamental physics tests that even a single pulsar orbiting Sgr A* would enable motivate searching for pulsars in EHT data sets. The high observing frequency means that pulsars—which typically exhibit steep emission spectra—are expected to be very faint. However, it also negates pulse scattering, an effect that could hinder pulsar detections in the Galactic center. Additionally, magnetars or a secondary inverse Compton emission could be stronger at millimeter wavelengths than at lower frequencies. We present a search for pulsars close to Sgr A* using the data from the three most sensitive stations in the EHT 2017 campaign: the Atacama Large Millimeter/submillimeter Array, the Large Millimeter Telescope, and the IRAM 30 m Telescope. We apply three detection methods based on Fourier-domain analysis, the fast folding algorithm, and single-pulse searches targeting both pulsars and burst-like transient emission. We use the simultaneity of the observations to confirm potential candidates. No new pulsars or significant bursts were found. Being the first pulsar search ever carried out at such high radio frequencies, we detail our analysis methods and give a detailed estimation of the sensitivity of the search. We conclude that the EHT 2017 observations are only sensitive to a small fraction (≲2.2 of the pulsars that may exist close to Sgr A*, motivating further searches for fainter pulsars in the region

EXPLORING BIOGRAPHIES: THE EDUCATIONAL JOURNEY TOWARDS BECOMING INCLUSIVE EDUCATORS OF CHILDREN WITH DISABILITIES

The current study explored the formative processes of twelve student teachers constructing role understandings in the context of their experiences and interactions with people with disabilities. In particular, it examined the participants’ changing notions of self-as-teacher and their unfolding perceptions of an inclusive educator’s role in teaching children with disabilities. The research aimed to investigate personal and professional forms of knowledge linked with the prior subjective life experiences of the student teachers and those arising from their interactions in situated learning experiences in community settings. The contextual framework of the study focused on the development of the student teachers’ unique understandings and awareness of people with disabilities through processes of biographical situated learning. The investigation examined participants’ voluntary out-ofcourse experiences with people with disabilities across three community settings for the ways in which these experiences facilitated the participants’ emerging role understandings. These settings included respite experiences in families’ homes of young children with disabilities receiving early intervention, an after-school recreational program for primary and secondary aged children and adolescents with disabilities, and an independent living centre providing post-school options and activities for adults with disabilities. ii Two groups participated in the current study, each consisted of six student teachers in the Bachelor of Education Course at the Bathurst campus of Charles Sturt University. Group One participants were in the second year compulsory inclusive education subject and Group Two participants were in the third year elective early intervention subject. The investigation examines the nature of reflexive and reflective processes of the student teachers from subjective, conflict realities in an attempt to link community experiences with real-life issues affecting inclusive educational practices. The voluntary community experiences engaged the research participants in multi-faceted interactions with people with disabilities, providing thought-provoking contexts for their reflections on observations, responses and reactions to situations, such as critical incidents. The participants engaged in reflexive and reflective processes in records made in learning journals and in semi-structured interviews conducted throughout the investigation. Results were analysed from a constructivist research paradigm to investigate their emerging role understandings. Prior to this study there had been few practical components in the compulsory undergraduate inclusive education subject which meant that previously student teachers gained theoretical knowledge without the opportunity to apply their learning. Many student teachers had expressed their feelings of anxiety and uneasiness about what they should do and say to a person with a disability. Thus, the community experiences were selected in order to give a specific context for student teachers’ learning and to provide participants with expanded opportunities to consider their professional identity, social awareness and acceptance of people with disabilities. iii An analysis of the data demonstrated the centrality of reflection within a situated teaching and learning framework. Understandings of prior experiences and motivation were shown to interact with the outcomes of the community experiences through an on-going process of reflection and reflexivity. This reconstructing process encouraged learners to reflect on past, present and projected future experiences and reframe actions from multiple perspectives as a way of exploring alternatives within broader contexts. The data reveal the participants’ engagement in the community experiences facilitated their awareness of wider socio-cultural educational issues, while focusing their attention on more appropriate inclusive teaching and learning strategies. The reflective inquiry process of identifying diverse issues led participants to consider other possible alternatives to current community practices for better ways to support their changing perspectives on ideal inclusive classroom practices. The dialogic nature of participants’ on-going deliberations contributed to the construction of their deeper understandings of an inclusive educator’s role. The findings of the study identified external environmental and internal personal factors as contributing biographical influences which shaped the student teachers’ emerging role understandings. The results emphasised the value of contextual influences in promoting desirable personal and professional qualities in student teachers. Importantly, situated learning enhanced participants’ unique interpretations of their prospective roles. As a result of analysing their insights from interactions in community contexts, the student teachers had increased their personal and professional understandings of individuals with disabilities and broadened their perceptions of their roles as inclusive educators. Thus, the study found that encouraging a biographical reflexive and reflective orientation in participants was conducive iv to facilitating changes in their understandings. Overall, the outcomes had benefits for student teachers and teacher educators in finding innovative ways for integrating biographical perspectives into situated teaching and learning approaches. The study showed that contextual influences facilitated deeper understanding of role identity and produced new ideas about the nature of reflexivity and reflection in guiding student teachers’ learning.

Enhancing performance and sustainability of community health worker programs in Uganda: lessons and experiences from stakeholders

Background: Community health worker (CHW) programs in Uganda have contributed to improved health outcomes in recent years. However, opportunities for engaging the various stakeholders supporting CHW programs have been limited. This article presents workshop findings where several stakeholders shared their lessons and experiences that can enhance performance and sustainability of CHW programs in Uganda. Methods: We collected qualitative data from stakeholders from government, private, and community organizations, as well as CHWs, involved in CHW programs in Uganda during a 1-day workshop. The workshop involved plenary presentations and group discussions on critical aspects of CHW programs. All proceedings from the workshop were audio-recorded, transcribed, and analyzed by thematic content analysis. Results: Four major themes emerged from the workshop: lessons learned in implementing CHW programs, challenges affecting CHW programs, performance of CHWs, and ensuring sustainability of CHW programs. Key lessons learned related to 3 main subthemes: capacity building and use of technology, supervision and motivation, and stakeholder engagement and collaboration. Challenges affecting CHW programs identified included poor coordination, fragmented data collection systems, high program expectations, inadequate support mechanisms, and high dropout rates. Mechanisms for improving the performance of CHWs emphasized the need to: strengthen recruitment, training, and retention strategies; improve motivation; streamline coordination mechanisms; and develop and strengthen community health policies. The sustainability of CHW programs requires institutionalization; sustainable funding; economic empowerment of CHWs; local ownership; and a strengthened research agenda. Conclusion: To improve the performance and sustainability of CHWs programs, stakeholders such as policy makers and implementing partners need to consider CHW needs, existing structures and policies, as well as local support
