A survey methodology was employed using a random sample of 25 Farmer Field School (FFS) members and 5 non=FFS members from each of the five locations of Marigat Division. In total, 100 FFS members and 25 non-FFS members participated in the study; addi- tional supplementary data were collected from the Kenya Forestry Research Institute (KEFRI), a major facilitator and trainer of the identified FFS activities and practices in the study area since 2004. More than 80% of the local community never undertook any form of prosopis management practice; however, this changed after FFS training, indicating an acquisition and retention of knowledge which probably diffused to the non-FFS counterparts, through either formal or informal ways. Harvesting was the most preferred (100%) and stump burning the least preferred (46%) practice of managing the spread of prosopis. The success and preference of any prosopis management practice was attributed to wood and non-wood benefits derived from prosopis and growing of animal fodder and food crops on rehabilitated land. More than 80% of respondents attributed ineffectiveness of any prosopis management practice to coppicing and viable seed banks of the tree, while 50% highlighted a lack of consistency and integration in carrying out manage- ment practices. The reported negative attitude towards prosopis changed after training with none of the view to eradicate it. Labor intensity and frequent regeneration of seedlings were identified as the major challenges faced during the implementation of proso- pis management practices. In conclusion, the study shows that harvesting, uprooting, stump burning, pruning and thinning realized through consistent holistic integration contribute to containing the spread of prosopis trees in Baringo, Kenya.展开更多

It is common among school children as they are easily injured during different school activities. Objective: The aim of this study was to assess the level of knowledge and attitude regarding first aid management of epistaxis among school teachers in Al-Ahsa, Saudi Arabia. Method: A cross sectional study was conducted in November 2017 among Saudi school teachers in AlAhssa region, Kingdom of Saudi Arabia. The data were collected by a well-structured online questionnaire which was designed including questions about the biographical data of the teacher, questions about the past knowledge of the emergency management of epistaxis and questions assessing the awareness of the method applied as a management of epistaxis. Result: We received 485 valid responses. 76% of teachers were female, 93% worked in public and 40% were in primary schools. 54% of participants had received information about first aid to stop nose bleeding or hemorrhage. 67% said that their students experienced epistaxis before. Interestingly, 15% said they would not try to stop the bleeding, and only 25% said they would press on the cartilaginous part of nose. However, a higher percentage (57%) knew that they should tilt the head forward.展开更多

This work took place over a period of 6 months from January 2019 to June 2019. The objective of this study was to study menstrual hygiene management in school?setting for girls aged 16 to 18 in two secondary schools in Bamako. It was a transversal and qualitative description. The study population consists of girls aged 16 to 18 years enrolled in one of the selected secondary schools.?At the end of this study, we arrived at the following results:?*50% of the girls in our study have poor knowledge about menstruation;?*10% of girls miss school at least one day a month during menstruation;?*90% of girls use hygienic cotton to absorb menstrual blood;?*90% of the sources of supply for hygienic products are?mothers.?The unsanitary conditions of the toilets, lack of light and the non-separation of the toilets according to gender guidelines were found in 99% of the cases: *99% of girls say that the poor state of health infrastructures was one of the causes of genital infections linked to poor management of menstrual hygiene;?*lack of water in the toilets (99%). Through these results, we conclude that,?in our context,?menstruation remains a taboo and shameful subject for girls. In addition, some of their menstrual hygiene practices are a real danger to their health.展开更多

One particular persisting challenge, which can be addressed by AI, is school dropouts whereby hundreds of thousands of children drop annually in Africa. This article presents a data-driven approach to proactively predict likelihood of dropping from schools and enable effective management of dropouts. The approach is guided by a carefully crafted conceptual framework and new concepts of average absenteeism, current cumulative absenteeism and dropout risk appetite. In this study, a typical scenario of missing quality data is considered and for which synthetic data is generated to enable development of a functioning prediction model using neural network. The results show that, using the proposed approach, the levels of risk of dropping out of schools can be practically determined using data that is largely available in schools. Potentially, the study will inspire further research, encourage deployment of the technologies in real life, and inform processes of formulating or improving policies.</span> </div>展开更多

The study involved interviews with school principals and analysis of their schools' financial statements. The aim of this project is to gain a current understanding of the issues and challenges facing primary schools in a defined region (Waikato) to see whether the trends identified in national research studies, confirms the problem that schools are underfunded. The results of the current study identified the issues experienced by the Waikato schools and in most cases supported previous research findings. The findings of the current study also suggest that schools share the dilemmas associated with limited government funding and rely significantly on local funding sources to achieve their basic objectives. Although schools may be effective in the management of their school objectives, there is more government funding required to relieve the pressures and challenges.展开更多

文摘The installation of small cells in a 5G network extends the maximum coverage and provides high availability.However,this approach increases the handover overhead in the Core Network(CN)due to frequent handoffs.The variation of user density and movement inside a region of small cells also increases the handover overhead in CN.However,the present 5G system cannot reduce the handover overhead in CN under such circumstances because it relies on a traditionally rigid and complex hierarchical sequence for a handover procedure.Recently,Not Only Stack(NO Stack)architecture has been introduced for Radio Access Network(RAN)to reduce the signaling during handover.This paper proposes a system based on NO Stack architecture and solves the aforementioned problem by adding a dedicated local mobility controller to the edge cloud for each cluster.The dedicated cluster controller manages the user mobility locally inside a cluster and also maintains the forwarding data of a mobile user locally.To reduce the latency for X2-based handover requests,an edge cloud infrastructure has been also developed to provide high-computing for dedicated controllers at the edge of a cellular network.The proposed system is also compared with the traditional 3GPP architecture and other works in the context of overhead and delay caused by X2-based handover requests during user mobility.Simulated results show that the inclusion of a dedicated local controller for small clusters together with the implementation of NO Stack framework reduces the significant amount of overhead of X2-based handover requests at CN.
文摘This study evaluates the extent to which primary schools in a region of New Zealand are challenged by limited funds to enable the effective management and performance of their school. The study involved interviews with school principals and analysis of their schools' financial statements. The aim of this project is to gain a current understanding of the issues and challenges facing primary schools in a defined region (Waikato) to see whether the trends identified in national research studies, confirms the problem that schools are underfunded. The results of the current study identified the issues experienced by the Waikato schools and in most cases supported previous research findings. The findings of the current study also suggest that schools share the dilemmas associated with limited government funding and rely significantly on local funding sources to achieve their basic objectives. Although schools may be effective in the management of their school objectives, there is more government funding required to relieve the pressures and challenges.
文摘In order to realize the high-quality and balanced development of the obligation education,school of collectivization has become an important measure.It promotes the fairness of education by expanding the coverage of high-quality education resources and sharing experience of education management.Its essence is the process of combining multiple individual schools in the region to form an organic organization of education group.In this process,school managers are faced with many problems such as remote management,increased difficulty in management,and increased cost of management.How to improve their leadership under collectivization has become a key issue of research.This study takes Jing'an District of Shanghai as an example,pays attention to the leadership of school managers under collectivization,in order to provide targeted suggestions for improving the leadership of school managers.This study analyzes the concept of school management leadership,and investigates the performance of three education groups and eight school managers in the aspects of structural leadership,teaching leadership,curriculum leadership and cultural value leadership.The study finds that school managers think that the main challenge after collectivization is the increase of management difficulty,followed by the expansion of school scale,insufficient policy support and insufficient resource allocation.In a word,these problems greatly affect the leadership level of school managers under collectivization.It thinks that school managers should optimize the organizational structure,build a modern school system,improve the professional level,promote the common development of teachers,build school culture and create a good organizational atmosphere to continuously improve their leadership.
