This study analysed the socio-economic contributions of N-Power programme amongst the beneficiaries of the scheme in Benue State.Prior to the introduction of N-Power programme,successive administrations in Nigeria have made concerted efforts towards improving the standard of living of the citizenry through the execution of various welfare or social intervention programmes,but not much successes were recorded.Learning from the mistakes of the past regimes,and by way of deliberate state policy,the Buhari’s government initiated a multi-pronged social investment policy,one of which is the N-power programme that came onboard in 2016,which also doubles as the subject of this study.To achieve the goal of this study,a combination of desktop research and survey design was employed.Questionnaires were administered to 390 respondents through a combination of stratified and random sampling techniques.The results of the survey were matched with that of the secondary data obtained through online websites and other related sources.The result indicated that N-Power made positive contributions to the socio-economic life of the beneficiaries in Benue State:specifically,the scheme contributed in poverty eradication,employment generation,skills acquisitions and capacity building.However,some aspect of our findings revealed that the programme has a number of challenges such as:inadequate cash support,delay in monthly cash transfer to beneficiaries,distance participants had to move to their work stations,absence of posting in N-Teach scheme,and lack of adequate working tools amongst others.To salvage this problem the paper recommended the following solutions:expansion of the scheme to cover N-Teach and other aspects,increment in the monthly cash transfer to cushion the high rate of inflation,support for the participants/beneficiaries in transportation and logistics,enrolment of more youth into the various schemes,proper monitoring and evaluation of the implementation of the schemes amongst others. 展开更多

Background Youth suicide has been a pressing public mental health concern in China,yet there is a lack of gatekeeper intervention programmes developed locally to prevent suicide among Chinese adolescents.Aims The current Delphi study was the first step in the systematic development of the Life Gatekeeper programme,the first gatekeeper programme to be developed locally in China that aims to equip teachers and parents with the knowledge,skills and ability to identify and intervene with students at high risk of suicide.Methods The Delphi method was used to elicit a consensus of experts who were invited to evaluate the importance of training content,the feasibility of the training delivery method,the possibility of achieving the training goals and,finally,the appropriateness of the training materials.Two Delphi rounds were conducted among local experts with diversified professional backgrounds in suicide research and practice.Statements were accepted for inclusion in the adjusted training programme if they were endorsed by at least 80%of the panel.Results Consensus was achieved on 201 out of 207 statements for inclusion into the adapted guidelines for the gatekeeper programme,with 151 from the original questionnaire and 50 generated from comments of the panel members.These endorsed statements were synthesised to develop the content of the Life Gatekeeper training programme.Conclusions This Delphi study provided an evidence base for developing the first gatekeeper training programme systematically and locally in China.We hope that the current study can pave the way for more evidence-based suicide prevention programmes in China.Further study is warranted to evaluate the effectiveness of the Life Gatekeeper training programme. 展开更多

Learning programming and using programming languages are the essential aspects of computer science education.Students use programming languages to write their programs.These computer programs(students or practitioners written)make computers artificially intelligent and perform the tasks needed by the users.Without these programs,the computer may be visioned as a pointless machine.As the premise of writing programs is situated with specific programming languages,enormous efforts have been made to develop and create programming languages.However,each program-ming language is domain-specific and has its nuances,syntax and seman-tics,with specific pros and cons.These language-specific details,including syntax and semantics,are significant hurdles for novice programmers.Also,the instructors of introductory programming courses find these language specificities as the biggest hurdle in students learning,where more focus is on syntax than logic development and actual implementation of the program.Considering the conceptual difficulty of programming languages and novice students’struggles with the language syntax,this paper describes the design and development of a Context-Free Grammar(CFG)of a programming language for the novice,newcomers and students who do not have computer science as their major.Due to its syntax proximity to daily conversations,this paper hypothesizes that this language will be easy to use and understand by novice programmers.This paper systematically designed the language by identifying themes from various existing programming languages(e.g.,C,Python).Additionally,this paper surveyed computer science experts from industry and academia,where experts self-reported their satisfaction with the newly designed language.The results indicate that 93%of the experts reported satisfaction with the NewBee for novice,newcomer and non-Computer Sci-ence(CS)major students. 展开更多

BACKGROUND Gastroparesis is a common digestive disorder characterized by delayed gastric emptying,which can lead to symptoms such as nausea,vomiting,abdominal pain,and poor appetite.Traditional Chinese medicine(TCM)has been used for centuries to treat gastrointestinal disorders,including gastroparesis.TCM theory suggests that spleen and stomach qi deficiency syndrome is one of the main pathogenic factors in gastroparesis.Nursing care plays an important role in the treatment of gastroparesis,and TCM nursing interventions have shown promising results in improving patient outcomes.However,there is limited research on the clinical effectiveness of TCM nursing interventions for gastroparesis with spleen stomach deficiency syndrome.This study aimed to evaluate the clinical effect of TCM nursing intervention in the treatment of gastroparesis with spleen stomach deficiency syndrome and to compare it with routine nursing interventions.AIM To analyze the clinical effect of traditional Chinese medicine nursing intervention in the treatment of gastric paraplegia with spleen stomach deficiency syndrome.METHODS From January 2020 to July 2021,80 patients with gastroparesis of spleen stomach qi deficiency type diagnosed in our hospital were selected for the study.The 80 patients were randomly divided into a control group and an experimental group,with 40 cases in each group.During the treatment period,the control group received routine nursing interventions,while the experimental group received traditional Chinese medicine nursing procedures.Compare the nursing effects of the two groups and observe the changes in traditional Chinese medicine symptom scores,pain levels,and sleep quality before and after treatment.RESULTS After treatment,comparing the treatment effects of the two groups,the total effective rate of the experimental group was significantly higher than that of the control group,with statistical significance(P<0.05).There was no statistically significant difference in the TCM symptom score,visual analogue scale(VAS)score,and Pittsburgh sleep quality index(PSQI)score between the two groups before treatment(P>0.05).However,after treatment,the TCM syndrome scores,VAS scores,and PSQI scores of the experimental group were significantly lower than those of the control group,with a statistically significant difference(P<0.05).CONCLUSION In the clinical nursing intervention of patients with mild gastroparesis due to spleen and stomach qi deficiency,the traditional Chinese medicine nursing plan has good clinical application value and nursing effect,and has a good effect on improving patients’pain and sleep quality. 展开更多
