Two independent types of log-normal particle size distributions were selected in the B-TEMOM model scheme, comprising large and small particles to represent background (i.e., the surrounding environment) and vehicle exhaust particles, respectively. Concentration distributions of exhaust and background particles derived using this model scheme were verified against results from a moving secti onal method and the bimodal quadrature method of moments, showing excellent agreement. The effects of vehicle tailpipe ex 让 cond 让 ions (e.g., exhaust particle concentrations and velocity), sulfurcontent, and relative humidity on the evoluti on of particles were investigated numerically. Both two-dimensional and three-dimensional numerical simulations showed that tailpipe exit velocity and relative humid让y did not greatly affect the steady-state concentrations or the diameters of particles in urban atmospheres. Although an increase in sulfur content had little effect on the particle concentration, it led to background particles with larger geometric average diameter entering the environment. This coupled CFD-B-TEMOM numerical model provides a simple but accurate and efficient method for studying bimodal aerosol dynamics.展开更多

Methods Quantitative and qualitative studies were conducted. The multi-stage and cluster sampling approach was adopted for the quantitative part of the study. A questionnaire was designed and 996 children and their keepers were interviewed. Principals, doctors or teachers of the primary schools, directors and child care nurses of kindergarten, and staff of immunization agencies were invited to take part in 12 focus group discussions; meanwhile, face-to-face individual in-depth interviews with 16 officials of the Health, Education and Governmental Departments at various levels were conducted. Results The total number of subjects was 996. 16.7% of the children in the study completed all the procedures of the National Immunization Programme. 34.3% of them had immunization certificates while the remainder 44.7% registered in immunization agencies. Factors, including the migrant children, doubt about vaccine efficiency, mother’s occupation and educational background, knowledge of the National Immunization Programme on targeted vaccines, played an important role in obtaining or not immunization certificates. 95% of the keepers interviewed thought the immunization certificates were useful; 94.8% of them considered the check was critical while only 3.6% of them thought it unnecessary. The first reason from those who found it unnecessary was that they feared that repeated immunization might affect their children’s health. The second reason was the cost of immunization, which some of them could not afford to pay. However, the Health Department expressed a favorable attitude to the checking scheme. Though the Education Department agreed that the scheme was essential, they worried that it would affect the enrollment rate.Conclusion In spite of the difficulty in administering immunization certificate check, the effort would be rewarding for raising the immunization coverage rate among the children in Guizhou Province.展开更多

Currently, university library generally put a strong emphasis on collection of academic literature, but has less attention on literature collections which reflect the situation of university location, or even worse, simply don' t launch business in this field. For the university library, it is a great loss of literature information resources, as well as a great regret of library work. First, what is the local literature? It is literature data which document a region' s past and present issues like politics, economy, culture, education, history, geography and other aspects like important characters and events, customs, folklore etc.展开更多

This recognition makes educational data mining a new growing research community. One way to achieve the highest level of quality in a higher education system is by discovering knowledge from educational data such as students’ enrollment data. Many mining tools that aim to discover exciting correlations, frequent patterns, associations, or casual structures among sets of items in educational data sets have been proposed. One of the widely used tools is association rules. In this paper, the Apriori algorithm is used to generate association rules to discover the importance and correlation between factors that influence student’s decision to enroll in higher education institutions in Sudan. The algorithm is applied using a student’s enrollment data set that was created using a questionnaire and 800 students enrolled in governmental and private sector universities as a sample. This paper classifies factors that influence enrollment into: student’s demographic factors and four categories of enrollment related factors (Student and Society, Educational Institution, Admission, and Employment related factors), and determines the most influential factors in determining student’s decision to enroll in Sudanese universities. The analysis result shows that the Educational Institution related factors (50%) and Admission related factors (40%) are strongly influencing students’ enrollment decision, while the Employment related factors (10%) and Student and Society related factors (0%) have weak influence. The factors out of the 14 Educational Institution related factors that have a high impact are: reputation, diversity of study, quality of education, education facilities, and feasibility.展开更多

Three research questions guided the study while three hypotheses were formulated and tested at 0.05 level of significance. The study was carried out in South East, Nigeria. Population for the study was 1340. Sample for the study was 753 obtained through proportionate (30%) stratified random sampling technique. A 38 item questionnaire was developed and used to collect data. Data obtained were analyzed using mean and standard deviation to answer research questions while t-test statistic was used to test hypotheses at probability of 0.05 level. It was found out by the study that 38 mobilization initiatives could be used to enhance students’ enrolment into Vocational and Technical Education Programs in Nigerian Universities. It was therefore recommended that the identified mobilization initiatives be implemented by relevant stakeholders to enhance secondary school students’ enrollment into VTE programs in Nigerian Universities.展开更多

Recruitment and retention models are beginning to be analyzed worldwide in an effort to assess how to conduct studies more efficiently, all the while, allowing researchers to provide sound and ethical data to help advance medicine through clinical studies. Sponsors and sites have recognized that clinical trial enrollment must become more diverse and inclusive. In this review, we address the important topics of recruitment and retention in clinical trials. Specifically, the obstacles in regard to recruiting vulnerable populations. Methodologies to improve both the understanding of the study population and community engagement are outlined. In particular, newer strategies such as use of social media and more reliable strategies such as trust and relationship building are described in detail. A strong focus on recruitment is becoming widely recognized as being of such importance that consideration is given to this key component even during initial protocol development. Attention to recruitment and retention in the strategic planning process of clinical trials can mitigate enrollment issues that clinical researchers are experiencing.展开更多

The 3 + 4 Pilot Program (three-year secondary vocational education and four-year undergraduate education) has been under experiment since 2014. It has attracted more and more academically good junior middle school graduates to secondary vocational schools with the national and local favorable policies and laws. Except the three-year’s hand-on practice, what appeals most to the junior middle school graduates is the academic transfer under the Program, a breakthrough in history of vocation education in China. However, only initiating a new program is not enough. Shanghai government should map out a long-term plan to set up promotion to increase the public awareness to change the long prevailing outdated ideology in order to add more to its appeal of the Program. There is still much work to be done before expanding the scope of the Program.展开更多

文摘Objective To study the feasibility of enforcing immunization certificate check before children enroll in primary schools or kindergartens in Guizhou Province. Methods Quantitative and qualitative studies were conducted. The multi-stage and cluster sampling approach was adopted for the quantitative part of the study. A questionnaire was designed and 996 children and their keepers were interviewed. Principals, doctors or teachers of the primary schools, directors and child care nurses of kindergarten, and staff of immunization agencies were invited to take part in 12 focus group discussions; meanwhile, face-to-face individual in-depth interviews with 16 officials of the Health, Education and Governmental Departments at various levels were conducted. Results The total number of subjects was 996. 16.7% of the children in the study completed all the procedures of the National Immunization Programme. 34.3% of them had immunization certificates while the remainder 44.7% registered in immunization agencies. Factors, including the migrant children, doubt about vaccine efficiency, mother’s occupation and educational background, knowledge of the National Immunization Programme on targeted vaccines, played an important role in obtaining or not immunization certificates. 95% of the keepers interviewed thought the immunization certificates were useful; 94.8% of them considered the check was critical while only 3.6% of them thought it unnecessary. The first reason from those who found it unnecessary was that they feared that repeated immunization might affect their children’s health. The second reason was the cost of immunization, which some of them could not afford to pay. However, the Health Department expressed a favorable attitude to the checking scheme. Though the Education Department agreed that the scheme was essential, they worried that it would affect the enrollment rate.Conclusion In spite of the difficulty in administering immunization certificate check, the effort would be rewarding for raising the immunization coverage rate among the children in Guizhou Province.

Recruitment and retention models are beginning to be analyzed worldwide in an effort to assess how to conduct studies more efficiently, all the while, allowing researchers to provide sound and ethical data to help advance medicine through clinical studies. Sponsors and sites have recognized that clinical trial enrollment must become more diverse and inclusive. In this review, we address the important topics of recruitment and retention in clinical trials. Specifically, the obstacles in regard to recruiting vulnerable populations. Methodologies to improve both the understanding of the study population and community engagement are outlined. In particular, newer strategies such as use of social media and more reliable strategies such as trust and relationship building are described in detail. A strong focus on recruitment is becoming widely recognized as being of such importance that consideration is given to this key component even during initial protocol development. Attention to recruitment and retention in the strategic planning process of clinical trials can mitigate enrollment issues that clinical researchers are experiencing.

文摘BACKGROUND There is an acute need to raise awareness of non-alcoholic fatty liver disease/nonalcoholic steatohepatitis(NAFLD/NASH)among primary care physicians,endocrinologists and diabetologists to improve patient identification and address the current difficulties in NASH clinical trial enrollment.We examined the extent of knowledge and practice regarding NASH diagnosis and management guidelines.A randomized online convenience survey of 12869 physicians drawn from a national physician database of primary care physicians(PCPs),and gastroenterology and endocrinology specialists were queried via online survey.Our results,based on a cohort of 185 respondents,showed gaps in knowledge and practice between these three groups of practitioners,with primary care providers having the lowest adherence to published guidelines for diagnosis of NASH.Without clear knowledge and patient identification at the point of presentation-which is often in primary care or with specialties other than hepatology–many patients with NAFLD and NASH will remain undiagnosed and untreated,and clinical studies will continue to struggle with patient recruitment,hindering clinical development and optimal patient care.AIM To determine knowledge base concerning NASH diagnosis amongst gastroenterologists,endocrinologists and primary care physicians to improve referrals into clinical trials.METHODS A randomized online convenience survey of 12869 physicians drawn from a national physician database of PCPs,and gastroenterology and endocrinology specialists was conducted yielding a sample of 185 respondents.RESULTS The survey revealed that many physicians are either unaware of testing options other than biopsy,or do not use them in practice.Only 46%of endocrinologists and 42%of primary care physicians indicated they would refer a patient for specialist workup if they suspected NASH.Risk(25%)and inconvenience to patients(18%)are given as reasons for not referring those with suspected NASH for biopsy.For standard diagnostic algorithms such as Fibrosis-4 score,18%of PCPs,30%of endocrinologists and 65%gastroenterologists reported using these tests in clinical practice.CONCLUSION Substantial gaps in knowledge of the differences between NAFLD and NASH exist between these physician groups,with knowledge being particularly low among primary care doctors and endocrinologists.The use of a simple noninvasive screening algorithm may help to identify the right patients for clinical trials,which in turn will be vital to the development of effective and welltolerated treatments for this increasingly ubiquitous condition.
文摘Secondary vocational education in Shanghai continues to experiment in an attempt to find ways to solve the decline of student enrollment and adjust to rapidly changing social and economic environments. The 3 + 4 Pilot Program (three-year secondary vocational education and four-year undergraduate education) has been under experiment since 2014. It has attracted more and more academically good junior middle school graduates to secondary vocational schools with the national and local favorable policies and laws. Except the three-year’s hand-on practice, what appeals most to the junior middle school graduates is the academic transfer under the Program, a breakthrough in history of vocation education in China. However, only initiating a new program is not enough. Shanghai government should map out a long-term plan to set up promotion to increase the public awareness to change the long prevailing outdated ideology in order to add more to its appeal of the Program. There is still much work to be done before expanding the scope of the Program.
文摘Cancer trials often start investigational therapy at diagnosis or after a selected number of relapses.These are the usual core inclusion criteria in clinical trials.Hence it is helpful when planning a trial to know the likely percentages of patients receiving standard therapy at clinics and hospitals who meet this key inclusion criteria of being newly diagnosed during a period or having just had their first,second or third relapse during an anticipated enrollment time frame.Often regulatory agencies will have approvals tied to the use of a therapy in a relapsed context or in a newly diagnosed context.We provide details on calculations to help those in clinical trial operations make realistic assessments on the number of sites and likely enrollment at clinical trial sites,and the enrollment time frames that might be needed to complete planned total patient enrollment.The estimates complement site feasibility questionnaires which are often sent to gauge patient availability and site interest.
文摘In this study,we are discussing the rationale behind informed consent in clinical trials in developing countries.It elaborates how informed consent has remained an ethical and practical issue.Poverty,endemic diseases,and a lack of investment in healthcare systems influence the ease of conducting and selecting trials that can benefit the people of developing countries.Differences in cultural perspectives,religious beliefs,a lack of formal training for clinical staff,children,time zone difference,literacy,vulnerable population,and language barriers for subject enrollment,protection,and informed are also challenges.This report doesn’t only highlight the right the wrongs of the past or reiterate cases where clinical trials have hurt subjects in developing countries.The current study investigates the conditions of human research in developing countries to make them more ethically sound.The extends proposals to investigators,scientists,governments,sponsors,and other groups who are interested where appropriate.
