Availability and accessibility to affordable health products are critical indicators towards achieving universal health coverage. Routine supportive supervision, performance monitoring, recognition of efforts and client feedback are vital activities toward health supply chain system strengthening. This is a descriptive paper that describes a model of integrated commodity supportive supervision, and mentorship and its impact on various outcomes of health commodity management. Data were abstracted from the standardized scored checklists used during integrated commodity supportive supervision and supply chain audit in public health facilities in Vihiga County. Scores for the period 2020 to 2022 were analyzed on the eight key areas of interest. The analysis was done using Statistical Package for Social Sciences (SPSS version 26). Results are interpreted at 95% Confidence interval. This paper also shares findings from both quantitative and qualitative data from client exit and facility managers’ interviews. Six complete rounds of supervisions, three clients and service providers’ interviews, and three annual award events have been conducted. We observed trends across six data collections points and compared the results at first point or baseline (January-June 2020) to the results at the last point or end line (April-June 2022). Findings show significant improvements on the eight parameters in terms of mean scores as follows: resolution of issues from previous visits by 35.06% (46.75% - 81.81%);storage of HPTs by 17.41% (68.72% - 86.13%);inventory management by 28.16% (42.67% - 70.83%);availability and use of commodity data management information systems (MIS) tools by 22.39% (74.40% - 96.79%);verification of commodity data by 25.61% (65.56% - 91.17%);availability of guidelines and job aids for commodity management by 46.28% (36.65% - 82.93%). There was an improvement on the mean score on accountability by 20.22% (58.58% - 83.51%). The composite (final) score improved by 28.33% (56.19% - 84.52%). There was progressive narrowing of the standard deviations on all the indicators across the study period. This demonstrates that there is standardization of practices and positive competition among all the public health facilities. There were significant improvements on all the eight indicators. Routine integrated commodity supportive supervision has proven to be an effective high impact intervention in improving management of health products and technologies in Vihiga County, Kenya.展开更多

It shares symptoms with other respiratory illnesses such as pneumonia and influenza, making rapid and accurate diagnosis essential to treat individuals and halt further transmission. X-ray imaging of the lungs is one of the most reliable diagnostic tools. Utilizing deep learning, we can train models to recognize the signs of infection, thus aiding in the identification of COVID-19 cases. For our project, we developed a deep learning model utilizing the ResNet50 architecture, pre-trained with ImageNet and CheXNet datasets. We tackled the challenge of an imbalanced dataset, the CoronaHack Chest X-Ray dataset provided by Kaggle, through both binary and multi-class classification approaches. Additionally, we evaluated the performance impact of using Focal loss versus Cross-entropy loss in our model.展开更多

The present paper compares the performance of two recurrent neural networks for rainfall-runoff modeling in the Zou River basin at Atchérigbé outlet. To this end, we used daily precipitation data over the period 1988-2010 as input of the models, such as the Long Short-Term Memory (LSTM) and Recurrent Gate Networks (GRU) to simulate river discharge in the study area. The investigated models give good results in calibration (R2 = 0.888, NSE = 0.886, and RMSE = 0.42 for LSTM;R2 = 0.9, NSE = 0.9 and RMSE = 0.397 for GRU) and in validation (R2 = 0.865, NSE = 0.851, and RMSE = 0.329 for LSTM;R2 = 0.9, NSE = 0.865 and RMSE = 0.301 for GRU). This good performance of LSTM and GRU models confirms the importance of models based on machine learning in modeling hydrological phenomena for better decision-making.展开更多

It can enhance the classification accuracy of decentralized SCN algorithms while effectively protecting user privacy. To this end, we propose a decentralized semi-supervised learning algorithm for SCN, called DMT-SCN, which introduces teacher and student models by combining the idea of consistency regularization to improve the response speed of model iterations. In order to reduce the possible negative impact of unsupervised data on the model, we purposely change the way of adding noise to the unlabeled data. Simulation results show that the algorithm can effectively utilize unlabeled data to improve the classification accuracy of SCN training and is robust under different ground simulation environments.展开更多

However, the acquisition of the psychomotor skills required for successful practice and learning can only be acquired if student midwives are supported and guided by clinical supervisors in their learning environments. Main Objective: The main objective of the study was to determine factors influencing clinical supervision of Student Midwives in Lusaka Urban District. Methodology: A cross-sectional study design that employed both quantitative and qualitative methods was used. The study population comprised 124 Nurses and Midwives working in Lusaka urban District. Self-administered questionnaires were used to collect data from the Nurses and midwives and a focus group discussion guide was used to guide discussions with the student midwives at Lusaka College of Nursing and Midwifery and a total of three focus group discussions were conducted. Quantitative data were entered into by Statistical Package Social Sciences (SPSS) version 22 for windows. Chi-square test was used to test associations among variables. The confidence interval was set at 95% with a significance level of 0.05. Qualitative data were analysed using content analysis to classify words into themes and categories by looking for repeated ideas or patterns of thoughts. Results: The findings showed that a high percentage of the clinical supervisors (89.5%) had not been trained in clinical supervision and most respondents had moderate knowledge on clinical supervision of students. Majority of the respondents (63%) exhibited inadequate supervision skills. The attitudes of all the supervisors towards supervision were positive. A large percentage of respondents (73%) were competent in clinical supervision. However the learning environment considered to be poor by most respondents (61%). The study revealed a significant association between clinical supervision and the respondents’ knowledge on clinical supervision (p-value of 0.00). Conclusion: The current study showed that clinical supervision was untrained and had inadequate supervision skills and the learning environment was poor. There is need therefore to train clinical supervisors and improve the students’ learning environment in order to enhance teaching and learning. The study offers a valuable insight into the factors influencing students’ midwives learning in clinical learning environment.展开更多

Access to resources is required for the development of a professional identity, which includes gaining technical knowledge and receiving feedback, guidance as well as social and emotional support from clinical supervisors. The aim of this study was to evaluate BSN students’ views of professional development after clinical supervision (CS) during their undergraduate education. An additional aim was to illuminate how competence development was related to the WHO Patient Safety Educational Model. A cross-sectional study was conducted, in which CS was measured as part of a survey completed by a sample of nursing students after their clinical placement at two time-points, namely 2012 and 2013. Statistical descriptive and inferential analyses were used and differences in the responses between Time 1 and Time 2 compared. The benefit of CS for nursing students’ competence development revealed a positive significant relationship between students’ Interpersonal skills and the factor Improved care/skills. There were differences in terms of variables related to the Importance value of CS and Professional skills. The results can be used to inform undergraduate nursing education leaders, teachers and practice partners on individual, group and organisational level in order to enhance patient safety and highlight the importance of CS for BSN students’ professional development.展开更多

Reputation mechanism is introduced and Bayesian approach is based on, in which government supervision as well as consumer purchasing behavior is taken as crucial factors to impact on the food quality security. As to the proposed quantitative indicators, government supervision includes exposure rate, fine and etc.;at the same time, consumer purchasing behavior includes consumer’s WTP for security food and consumer expectations to food safety. Taking China’s dairy industry as an example, it makes simulation by Netlog. The results show that consumer purchasing behavior alone has little effect on the dairy companies’ decision-making to be honest or counterfeiting enterprises. However, combination government supervision with purchasing behavior has great impact, and plays very good effects on food safety.展开更多

文摘The aim of this paper is to broaden the application of Stochastic Configuration Network (SCN) in the semi-supervised domain by utilizing common unlabeled data in daily life. It can enhance the classification accuracy of decentralized SCN algorithms while effectively protecting user privacy. To this end, we propose a decentralized semi-supervised learning algorithm for SCN, called DMT-SCN, which introduces teacher and student models by combining the idea of consistency regularization to improve the response speed of model iterations. In order to reduce the possible negative impact of unsupervised data on the model, we purposely change the way of adding noise to the unlabeled data. Simulation results show that the algorithm can effectively utilize unlabeled data to improve the classification accuracy of SCN training and is robust under different ground simulation environments.
文摘Characteristics of road landscaping were analyzed,as a kind of "linear" landscaping,it could be classified into urban street landscaping,urban ring road and expressway landscaping.Differences between road landscaping projects and other garden landscaping projects or construction projects were analyzed.Landscaping project for the South 3rd Ring Road of Xi'an City(in Yanta District)was taken for an example to summarize construction experience,discuss present conditions and features of garden landscaping supervision in China.The artistic and physiological properties of garden landscaping,as well as the supervision during maintenance period were stressed,but it was also pointed out that garden landscaping supervision in China was actually not given sufficient attention.On this basis,key points in the supervision of road landscaping project were proposed:understanding design ideas,selection of landscape plants,quality control of concealed works,prevention and control of diseases and insects,construction safety management and overall image;only by effectively implementing these key points,a high-quality road landscaping project could be realized to improve the image of a city and beautify its environment.

文摘Introduction: Clinical supervision plays a significant role in the acquisition of psychomotor skills by student midwives during training leading to the provision of high quality midwifery care. However, the acquisition of the psychomotor skills required for successful practice and learning can only be acquired if student midwives are supported and guided by clinical supervisors in their learning environments. Main Objective: The main objective of the study was to determine factors influencing clinical supervision of Student Midwives in Lusaka Urban District. Methodology: A cross-sectional study design that employed both quantitative and qualitative methods was used. The study population comprised 124 Nurses and Midwives working in Lusaka urban District. Self-administered questionnaires were used to collect data from the Nurses and midwives and a focus group discussion guide was used to guide discussions with the student midwives at Lusaka College of Nursing and Midwifery and a total of three focus group discussions were conducted. Quantitative data were entered into by Statistical Package Social Sciences (SPSS) version 22 for windows. Chi-square test was used to test associations among variables. The confidence interval was set at 95% with a significance level of 0.05. Qualitative data were analysed using content analysis to classify words into themes and categories by looking for repeated ideas or patterns of thoughts. Results: The findings showed that a high percentage of the clinical supervisors (89.5%) had not been trained in clinical supervision and most respondents had moderate knowledge on clinical supervision of students. Majority of the respondents (63%) exhibited inadequate supervision skills. The attitudes of all the supervisors towards supervision were positive. A large percentage of respondents (73%) were competent in clinical supervision. However the learning environment considered to be poor by most respondents (61%). The study revealed a significant association between clinical supervision and the respondents’ knowledge on clinical supervision (p-value of 0.00). Conclusion: The current study showed that clinical supervision was untrained and had inadequate supervision skills and the learning environment was poor. There is need therefore to train clinical supervisors and improve the students’ learning environment in order to enhance teaching and learning. The study offers a valuable insight into the factors influencing students’ midwives learning in clinical learning environment.
文摘Bachelor of Science Nursing (BSN) students’ education comprises both theories and practical aspects. Access to resources is required for the development of a professional identity, which includes gaining technical knowledge and receiving feedback, guidance as well as social and emotional support from clinical supervisors. The aim of this study was to evaluate BSN students’ views of professional development after clinical supervision (CS) during their undergraduate education. An additional aim was to illuminate how competence development was related to the WHO Patient Safety Educational Model. A cross-sectional study was conducted, in which CS was measured as part of a survey completed by a sample of nursing students after their clinical placement at two time-points, namely 2012 and 2013. Statistical descriptive and inferential analyses were used and differences in the responses between Time 1 and Time 2 compared. The benefit of CS for nursing students’ competence development revealed a positive significant relationship between students’ Interpersonal skills and the factor Improved care/skills. There were differences in terms of variables related to the Importance value of CS and Professional skills. The results can be used to inform undergraduate nursing education leaders, teachers and practice partners on individual, group and organisational level in order to enhance patient safety and highlight the importance of CS for BSN students’ professional development.
文摘This paper aims at the theoretical analysis to the impact of government supervision and consumer purchasing behavior on food quality security, so as to look for safety strategies and measures to strengthen and improve the level of food safety in China. Reputation mechanism is introduced and Bayesian approach is based on, in which government supervision as well as consumer purchasing behavior is taken as crucial factors to impact on the food quality security. As to the proposed quantitative indicators, government supervision includes exposure rate, fine and etc.;at the same time, consumer purchasing behavior includes consumer’s WTP for security food and consumer expectations to food safety. Taking China’s dairy industry as an example, it makes simulation by Netlog. The results show that consumer purchasing behavior alone has little effect on the dairy companies’ decision-making to be honest or counterfeiting enterprises. However, combination government supervision with purchasing behavior has great impact, and plays very good effects on food safety.
