The troubles...Global warming and climate change have made food production through conventional agriculture inefficient, and their effects on livestock and crop cultivation are leading to disruptions in the food supply. The troubles are severe in regions suffering from improper land management and unsustainable practices. The Bio-CircularGreen(BCG) economic model, designed to reduce and recycle resources by using environmentally friendly procedures, has been developed. The Azolla plant represents an interesting model for BCG and for enhancing community networks in Southeast Asia(SEA) because it provides multipurpose materials. Azolla can be used for various applications in agriculture such as biofertilizer and animal feed. However, our understanding and utilization of Azolla are limited. Moreover, collaboration among farmers is insufficient to maximize the benefits of Azolla. In this study, we provide a comprehensive review of the role of Azolla in agriculture. We review the main properties of Azolla as biofertilizers, especially regarding rice production and the interaction with cyanobacteria. For livestock, we discuss procedures to use Azolla in animal feed and evaluate the ingredients of the meal. In addition, we discuss product qualities from livestock treated with Azolla in the diet. This review also describes Azolla-based farming, which is designed for efficient land use and promotes nutrient cycling.Hence, we show that the Azolla plant is one of the key factors for farm-based agroecosystem services which can drive sustainable bioresource management in SEA. Moreover, we also propose the potential development of Azolla to improve its properties as a biofertilizer, a functional feed for animals and humans, and a feedstock for bio-oil production.展开更多

One of the sectors that recorded poor performance as a result of the slow growth of tourism is the hotel business. Despite this slack, stakeholders in Kenya have not tried to assess the extent to which the quality of this sector may impact on destination preference. The ultimate purpose of this research was to establish the quality gap between the expected and the perceived hotel product/service quality from both the perspective of the tourists and the hotel operators in Kenya. It was motivated by the need to create parameters that can elavate the competitiveness of Kenya＇s tourism using the hotel product/service quality offer. Descriptive quantitative research design was used to establish the secondary objectives and to assess two propositions set for the study. A sample of 211 tourists and 19 hotel operators in two major tourist provinces of Kenya was used to obtain information regarding normative and perceptive hotel product/service quality. Kenya＇s only destination marketing organisation, Kenya Tourist Board （KTB） marketers were also surveyed to provide insight on Kenya＇s destination position with regard to the motivation of tourists to visit Kenya. The study established that although the attractions which make tourists come to Kenya are the unique wildlife safari, beach tourism and the natural scenery, hotel product quality and hospitality plays a vital role in motivating tourists to choose Kenya as the destination to visit. However, this study found out that while the tourists and hotel operators agree on the normative hotel product quality level, there is a significant gap between the normative quality and the perceptual quality registered by tourists who used hotel services. The study established that hotel operators only recognize quality regulatory institutions with statutory and legal authority to incriminate facilities that do not comply with laid down operational requirements such as Hotels and Restaurants Authority and the Local Authority Public Health Department. The study has proposed an integrated framework that may be utilized to build a superior national hotel product/service quality so that the economic potential of tourism is maximized in Kenya.展开更多

Methods： From July 2004 to May 2006, 5 243 students from 14 universities in Shanghai took part in our survey. Topics covered the demands of reproductive health-care services, attitudes towards and experience with sex, exposure to pornographic material, and knowledge on sexual health and sexually transmitted infections （STIs）/AIDS. Results： Of the 5 067 students who provided valid answer sheets, 50.05% were female and 49.95% were male, 14.86% were medical students, and 85.14% had non-medical backgrounds. A total of 38.4% of respondents had received reproductive health education previously. The majority of students supported school-based reproductive health education, and also acquired information about sex predominantly from books, schoolmates, and the Internet. Premarital sexual behavior was opposed by 17.7% of survey participants, and 37.5% could identify all the three types of STIs listed in the questionnaire. Although 83.7% knew how HIV is transmitted, only 55.7% knew when to use a condom and 57.8% knew that the use of condoms could reduce the risk of HIV infection. Conclusion： The reproductive health service is lagging behind current attitudes and demands of university students. Although students＇ attitudes towards sexual matters are liberal, their knowledge about reproductive health and STIs/AIDS is still limited. It is therefore necessary to provide effective and confidential reproductive health services to young people.展开更多

文摘Mobile service robots(MSRs)in hospital environments require precise and robust trajectory tracking to ensure reliable operation under dynamic conditions,including model uncertainties and external disturbances.This study presents a cognitive control strategy that integrates a Numerical Feedforward Inverse Dynamic Controller(NFIDC)with a Feedback Radial Basis Function Neural Network(FRBFNN).The robot’s mechanical structure was designed in SolidWorks 2022 SP2.0 and validated under operational loads using finite element analysis in ANSYS 2022 R1.The NFIDC-FRBFNN framework merges proactive inverse dynamic compensation with adaptive neural learning to achieve smooth torque responses and accurate motion control.A two-stage simulation evaluation was conducted.In the first stage,the controller was tested in a simulated hospital environment under both ideal and non-ideal conditions.In the second,it was benchmarked against four established controllers-Neural Network Model Reference Adaptive(NNMRA),Z-number Fuzzy Logic(Z-FL),Adaptive Dynamic Controller(ADC),and Fuzzy Logic-PID(FL-PID)—using circular and lemniscate trajectories.Across ten runs,the proposed controller achieved the lowest tracking errors under all conditions.Under ideal conditions,it achieved average improvements of 55.24%,75.75%,and 55.20%in integral absolute error(IAE),integral squared error(ISE),and mean absolute error(MAE),respectively,with coefficient of variation(CV)reductions above 55%.Under non-ideal conditions,average improvements exceeded 64%in IAE,77%in ISE,and 66%in MAE,while maintaining CV reductions above 57%.These results confirm that the NFIDC-FRBFNN controller offers superior accuracy,robustness,and consistency for real-time path tracking in healthcare robotics.

文摘Global warming and climate change have made food production through conventional agriculture inefficient, and their effects on livestock and crop cultivation are leading to disruptions in the food supply. The troubles are severe in regions suffering from improper land management and unsustainable practices. The Bio-CircularGreen(BCG) economic model, designed to reduce and recycle resources by using environmentally friendly procedures, has been developed. The Azolla plant represents an interesting model for BCG and for enhancing community networks in Southeast Asia(SEA) because it provides multipurpose materials. Azolla can be used for various applications in agriculture such as biofertilizer and animal feed. However, our understanding and utilization of Azolla are limited. Moreover, collaboration among farmers is insufficient to maximize the benefits of Azolla. In this study, we provide a comprehensive review of the role of Azolla in agriculture. We review the main properties of Azolla as biofertilizers, especially regarding rice production and the interaction with cyanobacteria. For livestock, we discuss procedures to use Azolla in animal feed and evaluate the ingredients of the meal. In addition, we discuss product qualities from livestock treated with Azolla in the diet. This review also describes Azolla-based farming, which is designed for efficient land use and promotes nutrient cycling.Hence, we show that the Azolla plant is one of the key factors for farm-based agroecosystem services which can drive sustainable bioresource management in SEA. Moreover, we also propose the potential development of Azolla to improve its properties as a biofertilizer, a functional feed for animals and humans, and a feedstock for bio-oil production.

文摘The interplay between human and ecological systems has evolved from traditional conservation approaches to integrated socio-ecological frameworks that emphasise the co-production of ecosystem services.This paper aims to inspire new research pathways to advance the Nature's Contributions to People(NCP)perspective by focusing on terraced agroecosystems as emblematic landscapes that exemplify this co-production.Informed by recent studies in sustainability science,and drawing on our experience in Mediterranean environments,we explore the transformative potential of these frameworks for understanding and managing terraced landscapes.Addressing their multifunctionality,the challenges they face,and their socio-cultural and ecological significance,we highlight the importance of bridging scientific insights with local knowledge and participatory practices.We examine the use of advanced biophysical assessments,mapping tools,and stakeholder-driven approaches to enhance field assessment,monitoring capabilities and tackle management challenges under changing socio-economic conditions.We stress the urgent need for education and capacity-building initiatives to counteract indigenous knowledge loss and sustain traditional practices.Looking to the future,we propose potential avenues for research and practice that integrate ecological,cultural,and governance dimensions,contributing to the long-term sustainability of terraced landscapes and informing broader efforts for sustainable land management in an era of rapid environmental change.

文摘The theory of new quality productive forces provides a foundational framework for cultivating pre-service English teachers.There is a high degree of consistency between the development of new quality productive forces and the cultivation of pre-service English teachers.The development of new quality productive forces has put forward new requirements for the cultivation of pre-service English teachers,while the cultivation of pre-service English teachers will also promote the development of new quality productive forces and provide talent support for it.Currently,the cultivation of pre-service English teachers faces numerous challenges,which requires strengthening top-level program design,reconstructing the curriculum system,expanding cultivation fields for pre-service English teachers,improving the digital literacy of pre-service English teachers,deepening international exchanges and cooperation,and building an evidence-based evaluation system as a guarantee to achieve new breakthroughs in the cultivation of pre-service English teachers and promote the development of new quality productive forces.
文摘Kenya＇s tourism business stagnated from 1991 to 2003 and only registered small but steady grew from 2004. One of the sectors that recorded poor performance as a result of the slow growth of tourism is the hotel business. Despite this slack, stakeholders in Kenya have not tried to assess the extent to which the quality of this sector may impact on destination preference. The ultimate purpose of this research was to establish the quality gap between the expected and the perceived hotel product/service quality from both the perspective of the tourists and the hotel operators in Kenya. It was motivated by the need to create parameters that can elavate the competitiveness of Kenya＇s tourism using the hotel product/service quality offer. Descriptive quantitative research design was used to establish the secondary objectives and to assess two propositions set for the study. A sample of 211 tourists and 19 hotel operators in two major tourist provinces of Kenya was used to obtain information regarding normative and perceptive hotel product/service quality. Kenya＇s only destination marketing organisation, Kenya Tourist Board （KTB） marketers were also surveyed to provide insight on Kenya＇s destination position with regard to the motivation of tourists to visit Kenya. The study established that although the attractions which make tourists come to Kenya are the unique wildlife safari, beach tourism and the natural scenery, hotel product quality and hospitality plays a vital role in motivating tourists to choose Kenya as the destination to visit. However, this study found out that while the tourists and hotel operators agree on the normative hotel product quality level, there is a significant gap between the normative quality and the perceptual quality registered by tourists who used hotel services. The study established that hotel operators only recognize quality regulatory institutions with statutory and legal authority to incriminate facilities that do not comply with laid down operational requirements such as Hotels and Restaurants Authority and the Local Authority Public Health Department. The study has proposed an integrated framework that may be utilized to build a superior national hotel product/service quality so that the economic potential of tourism is maximized in Kenya.
文摘Aim： To promote the provision of reproductive health services to young people by exploring the attitudes and perceptions of university students in Shanghai, China, toward reproductive health. Methods： From July 2004 to May 2006, 5 243 students from 14 universities in Shanghai took part in our survey. Topics covered the demands of reproductive health-care services, attitudes towards and experience with sex, exposure to pornographic material, and knowledge on sexual health and sexually transmitted infections （STIs）/AIDS. Results： Of the 5 067 students who provided valid answer sheets, 50.05% were female and 49.95% were male, 14.86% were medical students, and 85.14% had non-medical backgrounds. A total of 38.4% of respondents had received reproductive health education previously. The majority of students supported school-based reproductive health education, and also acquired information about sex predominantly from books, schoolmates, and the Internet. Premarital sexual behavior was opposed by 17.7% of survey participants, and 37.5% could identify all the three types of STIs listed in the questionnaire. Although 83.7% knew how HIV is transmitted, only 55.7% knew when to use a condom and 57.8% knew that the use of condoms could reduce the risk of HIV infection. Conclusion： The reproductive health service is lagging behind current attitudes and demands of university students. Although students＇ attitudes towards sexual matters are liberal, their knowledge about reproductive health and STIs/AIDS is still limited. It is therefore necessary to provide effective and confidential reproductive health services to young people.

文摘The National Health Service(NHS)is a term used to describe the publicly funded healthcare delivery system providing quality healthcare services in the United Kingdom.There are several challenges militating against the effective laboratory service delivery in the NHS in England.Biomedical scientists work in healthcare to diagnose disease and evaluate the effectiveness of treatment through the analysis of body fluids and tissue samples from patients.They provide the"engine room"of modern medicine with 70%of diagnosis based on the laboratory results generated by them.This review involved the search of literature for information on working condition of biomedical scientist in the NHS in England.Laboratory service delivery in the NHS in England faces numerous daunting challenges;staffing levels in the last few years have become dangerously low,less remunerated,relatively less experienced and predominantly band 5's,multidisciplinary rather than specialty based,associated with working more unsocial hours without adequate recovery time,de-banding of staff,high staff turnaround,profit and cost driven rather than quality.These factors has resulted in burn out,low morale,high sickness absences,increased error rate,poor team spirit,diminished productivity and suboptimal laboratory service delivery.There is the urgent need to retract our steps on unpopular policies to ensure that patient care is not compromised by ensuring adequate staffing level and mix,ensuring adequate remuneralion of laboratory staff,implementing evidenced-based specialty oriented service,determining the root cause/s for the high staff turnover and implementing corrective action,identifying other potential sources of waste in the system rather than pruning the already dangerously low staffing levels and promoting a quality delivery side by side cost effectiveness.
