The rationale for this study was to analyse the mathematics teacher education curriculum by reflecting on lecturers', students and in-service teachers' perceptions. Mixed methods design particularly the convergent parallel design was used. Questionnaires were distributed to former university students who were teaching mathematics in Lusaka and Kitwe district of Zambia as well as final year student teachers who were on the programme and had done their school teaching experience. In addition, some teachers, lecturers of mathematics content and mathematics teaching methods were interviewed. The researcher used description and thematic analysis in analysing qualitative data and quantitative data was analysed through the use of the statistical package for social sciences version 20 where means and independent samples t-tests were used. The study key findings reviewed that the way teachers of mathematics were prepared for their professional classroom job was inappropriate as the curriculum they were exposed to during their teacher education programme was loosely linked to what the student teachers were expected to teach upon graduation in Zambian schools. This affected the way mathematics was taught in secondary schools. Besides, the mismatch in the two curricula led to teachers of mathematics with diplomas to divert to other teaching subjects when upgrading their studies to a degree level. Hence, it was recommended that the higher institutions of learning needed to consider the ministerial directive by reviewing the mathematics teacher education curriculum after thoroughly conducting a job analysis. It was also recommended that the Ministry of Education needed to reinforce the already existing continuous professional development to bridge the gap between the two curricula.

Of vital importance in the upholding of curriculum relevance in any society is the insurance that it is well contextualised or localised. When the curriculum is not contextualised and its implementation process not localised, the education system risk producing learners in a vacuum who may not eventually play a significant role in solving various societal glitches. If a country is to achieve rapid economic growth however, its education should be related to productivity (Bishop, 1985). Some of the solutions to problems currently encountered in African societies and communities Zambia inclusive, must proceed from understanding the dynamics with the local context. It is from this background that this study was undertaken to explore perspectives on practical measures and policies in enhancing the implementation of the localised curriculum in Mwansabombwe district of Zambia.

Despite this significant presence, national schooling systems have ignored, minimized, or ridiculed their histories pre-and post-Western contact, as well as their cultural contributions towards social and environmental sustainability. This in most cases has led to the education systems offered in most nations less relevant and unproductive for the masses. The sole purpose of any education system is to have a curriculum that offers relevant education to its learners. The aim of this paper therefore was to explore literature for the potentials of indigenising the school curriculum as a way of ensuring that curriculum relevance is upheld. For this to be successful, curriculum developers and policy makers should ensure that indigenous education must continuously re-invent itself so that it honours the basic cultural tenets of the ethnic groups it serves, recognizes the hybrid nature of many indigenous practices, and uses learning as a catalyst to foster social and environmental integrity. This paper therefore, concludes that there is a lot that can be learnt from indigenous education if its best practices are well synchronised with the formal curriculum thereby linking theory to practice for an effective curriculum.

Medicare Part D prescriber and prescription information for the most recent available year, 2017, was accessed via a publicly available database offered by the Centers for Medicare and Medicaid. Number of total prescriptions, number of opioid prescriptions, and the total days' supply of opioids prescribed were analyzed for each of 19,219 orthopaedic surgeons. Demographics and board certification status were also recorded. Orthopaedic surgeons who wrote the most opioid prescriptions (>400 per year) also wrote the longest prescription durations (14.1 days/prescription, P < .05 for all comparisons). Surgeons with more than 30 years of experience wrote the longest prescriptions (11.8 days/prescription; P < .001). Male surgeons wrote more opioid prescriptions than female surgeons (151 vs 95, respectively; P < .001). However, female surgeons wrote longer prescriptions than male surgeons (7.5 days/prescription vs 6.1 days/prescription, respectively; P = .01). Surgeons from southern states wrote the most opioid prescriptions (1,386,897) and the longest prescriptions, with an average of 13.0 days per prescription, whereas western states wrote the shortest prescriptions at 10.4 days per prescription (P = .004). There are demographic correlations between orthopaedic surgeons and opioid prescribing patterns. In particular, male, older southern surgeons prescribe the highest volumes of opioids. This provides an opportunity for targeted education versus overarching, general policies. Potential directions for future investigation can focus on assessing recent trends in opioid prescriptions among orthopaedic providers. Level III, retrospective cohort study.

While distal bicep tendon repair to the radial tuberosity has been demonstrated to restore function and strength, there is a lack of consensus on the optimal technique. The purpose of this Technical Note and video is to provide our preferred method of repair using an open, onlay-tissue fixation with all-suture anchors (FiberTak; Arthrex) and anatomic positioning of the biceps tendon on the radial tuberosity.

Utilization of wearable technology to monitor the pitching motion has several potential applications for injury prevention and postinjury rehabilitation. However, the device must be properly applied to collect meaningful data. Erratic or inconsistent measurements can be caused by inadequate battery charge, incorrect sensor placement, and inadvertent motion capture of fielding maneuvers or other nonpitching throws. These problems can be overcome with a protocol that includes collecting biomechanical data in real time and routinely checking the sensor position throughout the duration of the throwing session. In this article, we outline our protocol for collecting biomechanical data and troubleshooting suboptimal device function during pitching sessions.

Twenty DESIS images were used from three widely separated forested study sites representing deciduous and conifer forests. Gross primary production (GPP) values from eddy covariance flux towers at the sites were matched with DESIS spectral reflectances collected on the same days. Multiple algorithms were successful relating spectral reflectance with GPP, including: spectral vegetation indices (SVI) sensitive to chlorophyll content, SVI used in a photosynthetic light-use efficiency model framework, spectral shape characteristics through spectral derivatives and absorption feature analysis, and statistical models leading to multiband hyperspectral indices from partial least squares regression. Successful algorithms were able to achieve R 2 better than 0.7 using a diverse set of observations combining data from different sites from multiple years and at multiple times during the year. The demonstrated robustness of the algorithms provides some confidence in using DESIS imagery to map spatial patterns of GPP.

Among other subjects that the 2013 education curriculum framework brought on board was Computer Studies as a compulsory subject in both primary and junior secondary schools. Researchers in this study sought to analyse the availability of teaching and learning resources in the implementation of Computer Studies curriculum in selected public primary schools in Ndola district of Zambia given that this was a new subject that had not existed in the curriculum before. Qualitative research approach was used where the researchers employed the descriptive design. 54 primary schools which were clustered into 9 zones were targeted and the study sample comprised of 9 schools one from each of the 9 zones. A total of 72 respondents made up of 9 Head teachers, 18 teachers of Computer Studies and 45 learners ...
