Adoption of the New Primary School Curriculum in Zimbabwe: Implications for Staff Development and Quality Education

This is a qualitative case inquiry that sought to interrogate the adoption of the new primary school curriculum in Zimbabwe; with the broader goal of determining its implications for staff development and the delivery of quality education. The study is predominantly an extract of a PhD in Educational Management thesis that was submitted to Zimbabwe Open University in 2019; with the thesis aiming at appraising the effectiveness of primary school staff development programmes in Hwange District of Matabeleland North Province in Zimbabwe; in pursuit for quality education. In undertaking the current study, the author was conjointly assisted in the collection of data by the co-author of this article. For the purpose of attainability, the study was delimited to only five schools in the area under study. The target population of the study were primary school educators and the sample comprised of 30 educators (N=30), made up of 25 classroom practitioners (5 per school) and the head teacher from each of the 5 study sites. Purposive sampling was used to identify participants; while Focus Group Discussions (FGDs) and Interviews were used to generate data. Consistent with phenomenological inquiries, data were analysed through interpretive phenomenological analysis (IPA); while findings were presented in summarised prose form. The key findings of the study were that the adoption of the updated curriculum had necessitated the need for teachers‟ professional development in order to equip them with the necessary knowledge and pedagogic skills which they generally lacked considering that the teachers did not study new learning areas of the curriculum during their initial teacher training. In addition, there was lack of knowledgeable and competent facilitators in the new learning areas of the updated curriculum, hence, the inevitable need for staff development. The researchers concluded that the adoption of the updated primary school curriculum had been a major spur for staff development for teachers; hence, brought a new trajectory where teachers‟ continuous professional development is a necessity rather than an option if quality education is to be realised. The researchers, therefore, recommend that the Ministry of Primary and Secondary Education (MoPSE) should sustain its support for the continual staff development of primary school teachers considering that the adoption of the new curriculum in Zimbabwe has important ramifications for the delivery of quality education.
Effect of applying formic acid, heterolactic bacteria or homolactic and heterolactic bacteria on the fermentation of bi-crops of peas and wheat†

This work aimed to compare the effectiveness of bacterial inoculants or a chemical additive for preserving whole-crop silages made from wheat, two pea varieties (cv Magnus or Setchey) or intercrops of wheat and both pea varieties. The forages were harvested when the wheat and peas were at the late milk and yellow wrinkled stages respectively, and conserved in five replicate mini silos without treatment (control) or after treatment with 2.5 g kg−1 of formic acid (FA) or 1 × 106 cfu g−1 fresh forage of either of two bacterial inoculants (WholeCrop Gold (WCG) or WholeCrop Legume (WCL), Biotal Ltd, Cardiff, UK). WCG contained Lactobacillus buchneri, while WCL contained L buchneri, L plantarum and Pediococcus pentosaceus. Chemical composition, fermentation characteristics and in vitro digestibility were measured after 65 days of ensiling. Additive-treated bi-crops had lower (P < 0.05) concentrations of soluble N, ammonia N and lactic acid than the controls. Inoculant-treated bi-crops had higher (P < 0.001) acetic acid and lower (P < 0.001) residual water-soluble carbohydrate (WSC) concentrations than FA-treated bi-crops. WCL-treated bi-crops had similar residual WSC concentrations to and higher (P < 0.05) starch concentrations than WCG-treated bi-crops. Unlike Magnus pea bi-crops, Setchey pea bi-crops treated with WCL had lower concentrations of ammonia N (P < 0.01) and acetic acid (P < 0.001) and higher concentrations of starch (P < 0.001) and lactic acid (P < 0.05) than those treated with WCG. For both bi-crops, FA-treated bi-crops were more stable (P < 0.05) than inoculant-treated or untreated silages, and the stability of inoculant-treated and untreated silages was similar. Formic acid treatment was also the most effective at reducing WSC losses in the bi-crop and pea silages. Inoculant treatment reduced proteolysis in these forages but did not prevent spoilage in the bi-crops. Additive treatment reduced yeast counts but did not improve the fermentation in wheat silages.

Diagnosis of Dieback Disease of the Nutmeg Tree in Aceh Selatan, Indonesia

Effective control disease measures require a great deal of knowledge about the pathogen, which is also applied to dieback disease of the nutmeg tree in Aceh Selatan District, Province of Aceh, Indonesia. The objectives of this study were to identify the causal agent of dieback disease on a nutmeg plantation and to assess the effect of drought stress on the development of dieback disease. Pathogen identification was carried out by observing the symptoms of infected plants, morphological characters of the isolated pathogens, Koch’s postulates, and molecular analysis and pure pathogen cultures. The samples were taken from an infected part of the nutmeg plant (twigs, stems, and roots) in 6 subdistricts at the center of the nutmeg plantation in Aceh Selatan. Koch's postulates were performed by using the mycelia of pathogens on 1-year-old nutmeg seedlings. Drought stress was simulated everyday, and then once every 2 weeks, to study the effect of drought stress on dieback. The results showed that there were 4 genera of fungal pathogens (Botryodiplodia theobromae, Fusarium solani, Graphium euwallaceae, and Rigidoporus microporus) out of 6 fungi associated with dieback disease. However, B. theobromae Pat. turned out to be the dominant fungi associated with dieback on the nutmeg tree in Aceh Selatan. Drought stress was proven to be a predisposing factor for explaining this problem epidemic in Aceh Selatan.
Monitoring colour and fading: fluorescent pigments in works of art

Fluorescent pigments were first produced on a commercial scale in the mid 1940s, [ 1 ] and are now used in a variety of applications. Almost all fluorescent colours available are highly conjugated and unsaturated organic dyes dispersed in organic thermoplastic or thermosetting resins. Their bright appearance is caused by their ability to convert incident light into light of similar wavelength to the reflected light, resulting in an apparent reflectance greater than 100%. [ 2 ] Modem artists like Howard Arkley (1951-1999) have used fluorescent paints (Fig. 1) in order to produce optically vivid paintings. Problems with conventional colour measurement and identification using methods such as Raman [ 3 ] or UV-VIS spectroscopy were encountered: The use of three-dimensional fluorescence spectroscopy (3DF) is currently being examined as an alternative technique.

Smart “All Acrylate” ABA Triblock Copolymer Bearing Reactive Functionality via Atom Transfer Radical Polymerization (ATRP): Demonstration of a “Click Reaction” in Thermoreversible Property

Tailor-made ABA triblock copolymers (poly(furfuryl methacrylate)-b-poly(2-ethylhexyl acrylate)-b-poly(furfuryl methacrylate) (FEF)) bearing a reactive pendant furfuryl group were successfully synthesized by atom transfer radical polymerization. The chemical compositions were calculated by 1H NMR, and molecular weights and molecular weight distributions were determined by gel permeation chromatography analysis. The tensile properties of the triblock copolymers such as tensile strength, elongation at break, and tension set were studied. Differential scanning calorimetry (DSC) analysis and dynamic mechanical analysis (DMA) show the existence of two glass transition temperatures (Tg) and thereby the presence of well-defined soft and hard phase. Thermoreversible self-healing material was successfully prepared by using Diels−Alder reaction between this reactive furfuryl group (diene) of the ABA triblock copolymer and a bismaleimide (dienophile). Thermoreversible property of the polymer was confirmed by FTIR and.

As many as 80% of total stroke cases are ischemic strokes.1 Ischemic stroke occurs when the blood supply to the brain is disrupted due to occlusion that can be caused by thrombus or embolism or both.2 The hypoperfusion will be altered the function of the brain, resulting in neurological deficits and disability.13 This phenomenon causes limitations in patients to perform necessary activities of daily living (ADL). 4 The stroke patients experience changes in living their lives, such as changes in daily activities, social relationships, communication, and psychological conditions, both inpatients and in their families.4,5 These aspects are an indicator that shows an alteration in the quality of life of stroke patients.35
Review of Methods for Automatic Segmention of Brain Tumor in MRI Images

Efficient early detection of Brain tumors enable effective therapy thereby increasing survival rates. Even with growing progress in medical technology, brain tumor detection is an extremely complex task. The segmentation, detection, and extraction of infected tumor area manually from magnetic resonance (MR) images are effective but is a tedious and time taking task performed by radiologiest, which is based on their experience in the field. There are numerous automatic techniques which help in detection of brain tumor with higher degree of accuracy. However, the process of automatic detection and classification varies from technique to technique. Currently there is no particular reliable method widely accepted for tumor detection therefore automatic and reliable methods for tumor detection are of great need and interest. This review paper provides an overview of different methodologies practiced and the best technique adopted for higher accuracy in detecting tumors.

Two-dimensional modelling of uniformly doped silicene with aluminium and its electronic properties

Silicene is a two-dimensional (2D) derivative of silicon (Si) arranged in honeycomb lattice. It is predicted to be compatible with the present fabrication technology. However, its gapless properties (neglecting the spin-orbiting effect) hinders its application as digital switching devices. Thus, a suitable band gap engineering technique is required. In the present work, the band structure and density of states of uniformly doped silicene are obtained using the nearest neighbour tight-binding (NNTB) model. The results show that uniform substitutional doping using aluminium (Al) has successfully induced band gap in silicene. The band structures of the presented model are in good agreement with published results in terms of the valence band and conduction band. The band gap values extracted from the presented models are 0.39 eV and 0.78 eV for uniformly doped silicene with Al at the doping concentration of 12.5% and 25% respectively. The results show that the engineered band gap values are within the range for electronic switching applications. The conclusions of this study envisage that the uniformly doped silicene with Al can be further explored and applied in the future nanoelectronic devices.

Synthesis, Structure, Antioxidant, and Antiviral Studies on N2H5[Ln(edta)(H2O)3].5H2O (Ln = Pr, Nd, and Sm)

Single crystals of N2H5[Ln(edta)(H2O)3]. 5H2O (Ln = Pr, Nd and Sm) have been prepared and the molecular structures of these crystals were determined by X-ray single crystal study. The X-ray powder diffraction patterns of the three complexes reveal that they are isomorphous. These complexes are nine coordinated with a hexadentate edta4− ion and three coordinated water molecules. However, the remaining five more water molecules present as lattice water. Hydrazinium cation, though capable of coordination with the metal ion, in the present case present outside the coordination sphere as primary valency. The Ln(III)N2O4O′3 parts in the complex anions have the same structures in all the three complexes. The crystals of Pr(III), Nd(III), and Sm(III) complexes belong to the orthorhombic crystal system and Fdd2 space group. The crystal data are as follows: Pr(III): a = 19.6712(5) Å, b = 35.6939(9) Å, c = 12.3079(4) Å, α = β = γ = 90°, V = 8641.9(4) Å3, R = 0.0255, and Rw = 0.0728 for I>2σ (I) and 10119 reflections. Nd(III): a = 19.6414(3) Å, b = 35.6177(5) Å, c = 12.3212(2) Å, α = β = γ = 90°, V = 8619.7(2) Å3, R = 0.0251, and Rw = 0.0693 for I > 2σ (I) and 7378 reflections. Sm(III): a = 19.5814(3) Å, b = 35.4617(7) Å, c = 12.2931(2) Å, α = β = γ = 90°, V = 8536.2(3) Å3, R = 0.0233, and Rw = 0.0641 for I > 2σ (I) and 6766 reflections. These complexes show promising antioxidant activity as expected for lanthanide(III) ions with unpaired electrons. The antiviral screening also shows enhanced activities of these complexes than the respective non-hydrazinium and ammonium chelates. The crystals of the complexes in purest form were powdered and subjected to constant temperature degradation at 600°C to yield pure fine powders of the respective oxides. The microstructures of the oxides were studied by scanning electron microscope photographs.
Effects of Bias Voltage on the Structure and Mechanical Properties of Thick CrN Coatings Deposited by Mid-Frequency Magnetron Sputtering

Thick CrN coatings were deposited on Si (111) substrates by electron source assisted mid-frequency magnetron sputtering working at 40 kHz. The deposition rate, structure, and microhardness of the coatings were strongly influenced by the negative bias voltage (Vb). The deposition rate reached 8.96 μm/h at a Vb of −150 V. X-ray diffraction measurement revealed strong CrN (200) orientation for films prepared at low bias voltages. At a high bias voltage of Vb less than −25 V both CrN (200) and (111) were observed. Large and homogeneous grains were observed by both atomic force microscopy and scanning electron microscopy in samples prepared under optimal conditions. The samples exhibited a fibrous microstructure for a low bias voltage and a columnar structure for Vb less than –150 V.
Impact of Antarctic Meltwater Forcing on East Asian Climate Under Greenhouse Warming

In recent decades, Antarctic ice sheet/shelf melting has been accelerated, releasing freshwater into the Southern Ocean. It has been suggested that the meltwater flux could lead to cooling in the Southern Hemisphere, which would retard global warming and further induce a northward shift of the Intertropical Convergence Zone (ITCZ). In this study, we use experimental ensemble climate simulations to show that Antarctic meltwater forcing has distinct regional climate impacts over the globe, leading in particular to regional warming in East Asia, which offsets the global cooling effect by the meltwater forcing. It is suggested that Antarctic meltwater forcing leads to a negative precipitation anomaly in the Western North Pacific (WNP) via cooling in the tropics and the northward shift of the ITCZ. This suppressed convection in WNP induces an anticyclonic flow over the North Pacific, which leads to regional warming in East Asia. This hypothesis is supported by analyses of interensemble spread and long‐term control simulations.

Brand communication on Instagram during the COVID-19 pandemic: perceptions of users and brands

Social media, based on user-generated content, connectivity, and participation, have become a new environment for brands to capture attention and build lasting relationships with customers and fans. Participating in these platforms demanded a paradigmatic shift in branding and brand communication, who became more focused on listening to consumers and fans, interacting and collaborating with them, and nurturing mutually beneficial relationships. Digital influencers act as mediators between brands and their followers and play a pivotal role in Instagram marketing strategies. The COVID-19 pandemic, and the resulting confinement of the population and emergency status adopted in many countries, is having a profound impact on brands. Many of them, unable to produce and market their products or offering their services, are focusing on their communication, on remaining relevant or becoming more relevant for their fans and customers. Brand communication on Instagram has changed during this short period, and our exploratory study sets out to map the main changes and to understand how both brands, influencers and users perceive them. This article presents results from an online survey to a purposive sample of 160 Instagrammers, addressing their perceptions about the impact of these changes on their relationship with brands and influencers. We complement the perspective of users with interviews to 25 other relevant agents, namely Instagram influencers, marketing agencies and brands with relevant presence on Instagram.
