The readiness of schools in Zimbabwe for the implementation of early childhood education
This qualitative study focuses on primary schoolsâ state of readiness for the introduction of early childhood education. Adopting a multiple case study design, the article explores, through semi-structured interviews and documentation, school heads, teachers-in-charge and classroom teachersâ perceptions of their respective schoolsâ state of readiness for the installation and implementation of early childhood education. The study established that, while classroom teachers were adequately qualified to implement early childhood education, teachers-in-charge were not. Secondly, school heads received limited induction for the introduction and implementation of early childhood education. Additionally, inadequate teaching-learning resources and lack of on-going teacher support contributed to schoolsâ lack of readiness for the introduction of early childhood education. The study recommends interventions that curriculum planners and implementers can utilise in order to create conditions that enable primary schools to be ready for introducing and implementing early childhood education.Keywords: early childhood education; implementation; primary school; school readines
The Control of Nuisance Aquatic Vegetation with Black Polyethylene Plastic
Large sheets of black polyethylene plastic were to control nuisance aquatic vegetation in small farm ponds and lakes. The plastic was floated over vegetation beds and left unattended for a predetermined number of days. Adequate control of all species of Potomageton was achieved in 10 to 18 days. Ceratophyllum demersum was eliminated in the control plots in 18 to 28 days. Control was unsuccessful for Chara vulgaris and Saggattarius latifolia. All control plots were revegetated with filamentous algae within 30 days after the covering was removed
COVID-19 in rural Malawi: Perceived risks and economic impacts
Malawi reported its first case of COVID-19 in April and declared a national emergency. Schools, bars and restaurants were closed, international flights suspended, and the economy faced considerable disruptions: quarterly growth projections from July were cut by more than 60% (Saldarriaga Noel et al. 2020). While still concerning, compared to other countries and other parts of the world, the spread of this disease in Malawi has been relatively modest with 5,951 confirmed cases and 184 COVID-19 linked deaths as of November 8, 2020. After accelerating rates of infection in June and July, the rates have decreased over the last two months. In response, there has been a partial return to normalcy, marked by easing COVID-19 restrictions and the reopening of schools at the beginning of September, even while the future trajectory of the disease remains unknown
COVID-19 in rural Malawi: Perceived risks and economic impacts round 2
This note summarizes perceptions of COVID-19 impacts and risks from a panel phone survey of rural households in eight districts in rural Malawi. While the results from the first round conducted in August 2020 were reported in a previous brief, this note will focus on the evolution of indicators from round 1 to round 2, conducted in November 2020. The sample comprises 833 households interviewed in both survey rounds. Two additional follow-up survey rounds are planned for 2021. The survey was originally designed to measure the seasonality of labor activities but was adjusted to assess COVID-19 impacts and perceptions in rural Malawi. Though initial concern of the impact of COVID-19 on Malawi was high at the start of the global pandemic, case numbers stayed relatively low through the end of 2020. Seven-day averages of 50-100 cases during the first survey round had dropped to under 5 in the fourth quarter of the year. Our analysis will examine how peopleâs perceptions evolved during this period of low infections
Rationality as the Rule of Reason
The demands of rationality are linked both to our subjective normative perspective (given that rationality is a person-level concept) and to objective reasons or favoring relations (given that rationality is non-contingently authoritative for us). In this paper, I propose a new way of reconciling the tension between these two aspects: roughly, what rationality requires of us is having the attitudes that correspond to our take on reasons in the light of our evidence, but only if it is competent. I show how this view can account for structural rationality on the assumption that intentions and beliefs as such involve competent perceptions of downstream reasons, and explore various implications of the account
Complications among colorectal cancer survivors: SF-6D preference-weighted quality of life scores
Background
Societal preference-weighted health-related quality of life (HRQOL) scores enable comparing multi-dimensional health states across diseases and treatments for research and policy.
Objective
To assess the effects of living with a permanent intestinal stoma, compared to a major bowel resection, among colorectal cancer (CRC) survivors.
Research Design
Cross-sectional multivariate linear regression analysis to explain preference-weighted HRQOL scores.
Subjects
Six-hundred-forty CRC survivors (â„5 years) from three group-model HMOs; ostomates and non-ostomates with colorectal resections for CRC were matched on gender, age (±5 years), time since diagnosis, and tumor site (rectum vs. colon).
Measures
SF-6D scoring system applied to Medical Outcomes Study Short Form-36 version 2 (SF-36v2); City of Hope Quality of Life-Ostomy (mCOH-QOL-O); Charlson-Deyo comorbidity index.
Methods
Survey of CRC survivors linked to respondentsâ clinical data extracted from HMO files.
Results
Response rate was 52%. Ostomates and non-ostomates had similar sociodemographic characteristics. Mean SF-6D score was 0.69 for ostomates, compared to 0.73 for non-ostomates (p <.001), but other factors explained this difference. Complications of initial cancer surgery, and prior-year comorbidity burden and hospital use were negatively associated with SF-6D scores, while household income was positively associated.
Conclusions
CRC survivorsâ SF-6D scores were not associated with living with a permanent ostomy after other factors were taken into account. Surgical complications, comorbidities, and metastatic disease lowered the preference-weighted HRQOL of CRC survivors with and without ostomies. Further research to understand and reduce late complications from CRC surgeries as well as associated depression is warranted
The Role of Microbial Exopolymers in Determining the Fate of Oil and Chemical Dispersants in the Ocean
The production of extracellular polymeric substances (EPS) by planktonic microbes can influence the fate of oil and chemical dispersants in the ocean through emulsification, degradation, dispersion, aggregation, and/or sedimentation. In turn, microbial community structure and function, including the production and character of EPS, is influenced by the concentration and chemical composition of oil and chemical dispersants. For example, the production of marine oil snow and its sedimentation and flocculent accumulation to the seafloor were observed on an expansive scale after the Deepwater Horizon oil spill in the Northern Gulf of Mexico in 2010, but little is known about the underlying control of these processes. Here, we review what we do know about microbially produced EPS, how oil and chemical dispersant can influence the production rate and chemical and physical properties of EPS, and ultimately the fate of oil in the water column. To improve our response to future oil spills, we need a better understanding of the biological and physiochemical controls of EPS production by microbes under a range of environmental conditions, and in this paper, we provide the key knowledge gaps that need to be filled to do so
