Distribution of primary school based on spatial network comprehensive model in low-income mountainous cities： a case study in Wanyuan, China

Focusing on the peculiarities of urban construction resulting from specific mountain terrains, the purpose of this study is to find out a suitable method based on a Spatial Network Comprehensive Model(SNCM) to reasonably plan and distribute primary schools in low-income mountain cities. The construction principles and advantages of the SNCM method are proposed and the method tested in Wanyuan city of Qinba Mountain area(Southwest China) to verify its feasibility and optimization. Taking account of the mountain terrain and its influence on user behavior, we used the SNCM method to build a comprehensive model which integrates the road slope and the walking speed of pupils into the basic spatial model. The model is used to calculate a reasonable layout of the primary schools and to validate the rationale. The results show that the SNCM method can be effectively applied in low-income mountainous cities. It can not only improve the accessibility and service efficiency of primary schools using as little capital-investment as possible, but also help the city grow in an intensive and efficient way.

Optimization Model for School Transportation Based on Supply-Demand Analyses

This paper presents a new conception model of school transportation supply-demand ratio (STSDR) in order to define the number of school buses needed in a limited area and to describe the conditions of school transport system. For this purpose, a mathematical equation was elaborated to simulate the real system based on the school transport conditions and on the estimated results of STSDR from 15 zones of Cuenca city in Ecuador. The data used in our model was collected from several diverse sources (i.e. administrative data and survey data). The estimated results have shown that our equation has described efficiently the school transport system by reaching an accuracy of 96%. Therefore, our model is suitable for statistical estimation given adequate data and will be useful in school transport planning policy. Given that, it is a support model for making decisions which seek efficiency in supply and demand balance.

Peer Pressure and Family Smoking Habits Influence Smoking Uptake in Teenage Boys Attending School: Multilevel Modeling of Survey Data

Introduction: Among young teens, about one in five smokes worldwide. Adolescents spend a considerable amount of their time in school, and the school environment is therefore important for child health practices and outcomes. Objectives: We aimed to investigate the impact on smoking behavior of the school environment and the personal characteristics of male teenage students attending schools in Pakistan, taking into account the survey sampling structure. Methods: A two-stage cluster sampling with stratification was employed, and we interviewed 772 male secondary school students. We adopted random effect and generalizing estimating equation models. Results: Peer pressure in particular had a strong influence on adolescents smoking;those whose friends smoked were up to 6 times more likely to smoke. Family smoking was also significantly associated with adolescents smoking, but those students whose mother was educated were 50% less likely to smoke. The fitted random effect model indicated that the between school variability was significant (p-value < 0.01), indicating differences in smoking habits between schools. A random coefficient model showed that variability among schools was not significantly different for public and private schools. Conclusion: Public health campaigns for smoking cessation should target not only the individual but also the families of adolescents attending schools.

The Application of the Trial-Discovery Model to English Grammar Teaching in Senior High Schools

In senior high schools, great importance and attention are required to be attached to grammar teaching and learning. However, a majority of teachers either apply the traditional method or neglect grammar teaching and learning, both of which go against the ideas of the new curriculum of the high school. To solve the problem, based on the constructionist theory, Halliday＇s theory of register, and the trial-discovery model, the trial-discovery English grammar teaching model was constructed. To find out whether this teaching model is more effective than the traditional grammar teaching, an experimental study of the trial-discovery model in senior English grammar teaching is carried out. This study deals with the problem how we can improve the efficiency of grammar teaching, that is by increasing the students＇ learning interest and improving the accuracy in English writing. After the analysis of qualitative and quantitative data collected through questionnaires, interviews, and writing tests, the study reveals that the trial-discovery grammar teaching is more effective to stimulate the students＇ interest in learning grammar, and is more helpful to improve the accuracy and complexity in English writing than the traditional grammar teaching

Prediction and Backtracking Models of Life Cycle Cost Based on School Facility Conditions in South Korea

After the introduction of BTL （Build-Transfer-Lease） projects in 2005, most construction projects of school facilities have been implemented in BTL system. However, concern about whether the school facilities can be managed appropriately during the 20 year as operation and management period is increasing. Therefore, the necessity of reference for evaluation standard on operating costs and the establishment of LCC （life cycle costing） prediction models is coming to the fore. In this respect, the goal of this study was to extract the variables for LCC-related models and conduct analyses of the correlations of the variables using statistical analysis tool, in order to establish LCC prediction and backtracking model based on BTL project cases of school facilities. The prediction and backtracking model of LCC will be a key for budget equalization or optimum range as one way of estimating method using LCC by year and school type. In the future, it would provide the accurate reference for analyzing and managing the actual input costs against the plan and evaluating the practical cost for long-term facility management plan as the predictive management.

The Curriculum Problem Is the Basis of Model School Construction

This thesis makes vocational school demonstration project as a starting point. It is a combination of the last ten years of literature on model school building. From the perspective of the audience, it is combing the characteristics of the project due to the inherent requirements of the decision-making level, which is leading to its subordinate business operating space that has very limited level and then free the needs of the audience. It believes that if it relaxes contemplation perspective, consolidates construction of the curriculum, or it is a prime choice related to project management.

Reform of the Teaching Model of Korean Intensive Reading Courses in Vocational High Schools in the Era of All-Media

The use of multimedia technology in the teaching process is the current mainstream trend in teaching development.The arrival of the all-media era is not only a huge challenge to the traditional teaching model,but also a huge opportunity for the reform of the teaching model.Combining traditional education models with modern scientific and technological means,and learning from each other’s strengths can stimulate students’subjective initiative in learning.On the other hand,it is also an important way for teachers to improve their teaching abilities.This article analyzes the opportunities brought by the all-media era to the reform of education models based on the teaching status and teaching difficulties of Korean intensive reading courses in vocational high schools,and proposes a teaching model reform strategy for Korean intensive reading courses in vocational high schools in the all-media era.

Exploration of the Role-Playing Model in Primary School Class Activities Under the Background of“Class Activity Month”

Education in the new era advocates taking students as the main body and improving students’core literacy on this basis.Subjectivity has also become one of the keys to quality education.Primary school is not only the initial stage of life,but also the key period to develop students’subjectivity.At present,there are many problems in class activities,such as the weak concept of taking students as the main body,the lack of subject consciousness among students,the flawed construction system of class activities,the unreasonable evaluation system of class activities,and so on.By establishing the role-playing model under the background of“class activity month,”students can play different roles in class activities and participate in various links,such as theme selection,scheme design,organization,implementation,summary,and evaluation of class activities.Through this process,it does not only improve the quality of class activities,but also cultivate students’subject consciousness and ability in a certain subject,thus highlighting their subject status in class activities.

Parental Psychological Control and Internet Gaming Disorder Tendency:A Moderated Mediation Model of Core Self-Evaluation and Intentional Self-Regulation

Internet gaming disorder(IGD)among junior high school students is an increasingly prominent mental health concern.It is important to look for influences behind internet gaming disorder tendency(IGDT)in the junior high school student population.The present study aimed to reveal the explanatory mechanisms underlying the association between parental psychological control(PPC)and internet gaming disorder tendency among junior high school students by testing the mediating role of core self-evaluation(CSE)and the moderating role of intentional self-regulation(ISR).Participants in present study were 735 Chinese junior high school students who completed offline self-report questionnaires on parental psychological control,core self-evaluation,intentional self-regulation,and Internet gaming disorder tendency.Analyses were conducted via mediation and moderated mediation.The results showed that:(1)Parental psychological control was positively related to junior high school students’Internet gaming disorder tendency.Core self-evaluation,and intentional self-regulation were negatively related to junior high school students’Internet gaming disorder tendency,respectively.(2)Core self-evaluation partially mediated the relationship between parental psychological control and junior high school students’Internet gaming disorder tendency.(3)Intentional self-regulation moderated the association between parental psychological control and Internet gaming disorder tendency,as well as the relationships between parental psychological control and core self-evaluation and core self-evaluation and Internet gaming disorder tendency in the mediated model.Based on these findings,we believe that there is a need to weaken parental psychological control,strengthen junior high school students’core self-evaluation and intentional self-regulation,and to recognize the important role of parents as well as their children’s personal positive traits in the healthy development of junior high school students.

Towards a New Model of Teacher Training in Europe

The current situation of European educational systems leads to the lack of historical precedents,considering that it implies the end of educational systems based on exclusion,configuring a new conception of educational systems that we are still not able to appreciate at their true value,because we were educated by and in the previous educational system.Lacking other references,we inevitably tend to compare current problems with previous situations,without understanding that the generalization of education to 100%of the population implies a qualitative change that modifies the objectives,forms of work,and the very essence of the educational system.This stage change,marked by the acceleration of social changes,including the pandemic situation,explains why,despite the best educational system so far,teachers with the best levels of training and a financial and material endowment unimaginable until recently,try a sense of crisis and a general feeling of confusion is manifested among the teachers and parents of the children,seeing that education is no longer what it used to be(Esteve,1998).The key to defuse this apparent paradox is in the tendency to judge the new education system by the mentality and standards of the former selective education,in which most of the adults present were educated.Thus,although we continue to apply to the new general education situation the parameters of the previous situation,in which the selective system excluded every year the students who had behavior problems in the class or had difficulties regarding the mastery of certain educational subjects(Esteve,1998).In this way,we are currently criticizing the school failure of a percentage of our students,without realizing that their schooling itself is a success,because,although their level is low,they had no level before.One speaks of a low educational level,when,in reality,the educational level is increasing—the general level of the people and the individual level of the best students(Baudelot&Establet,1990).Indeed,it is true that in our education systems there are students with a very low educational level,although even so,it is a success that they have some education because they used to be on the streets;and,in any case,the current education system produces a higher percentage of students with higher levels than the best students of the 90s.The main element of change,the most substantial transformation,is the elimination of exclusion,today having access to secondary education,alongside students with an excellent level.Thousands of children who were previously expelled from it,thus comply with the European measures of access to education for all children and young people.The previous educational system can be compared to a hospital from which the sickest were kicked out,and those who created behavioral problems were eliminated through the selective mechanisms of the system.However,teaching today is qualitatively different from what it was 20-30 years ago.First of all,because working with a homogeneous group of children as a result of the selection or dealing with all the children in a country,with social and personal problems,is not the same thing.That is why many general education teachers are social workers rather than teachers;and the new configuration of our educational systems requires secondary teachers to assume diverse educational roles rather than the traditional one of intellectual training.History cannot go backwards;to have better quality educational systems,the solution is not to return to the exclusionary system.Society asks teachers to make an effort to integrate;but,during this time,our society must support and revalue the activity of teachers in order not to put them in front of impossible tasks.The transition from a selective to a general education was based on the increase/amplification of compulsory schooling.For the first time in history,European educational systems have assumed the role of declaring secondary education compulsory.This decision implies a new stage,a definitive break from the previous reality in which secondary education was reserved for those who later attend a university.

Modeling Spatial Opportunity Structures and Youths’ Transitions from School to Training

This paper examines the significance of spatial externalities for youths’ school-to-training transitions in Germany. For this purpose, it is necessary to address the methodological question of how an individual’s spatial context has to be operationalized with respect to both its extent and the problem of spatial autocorrelation. Our analyses show that the “zone of influence” comprises of the whole of Germany, not only close-by districts, and that these effects differ between structurally weak and strong regions. Consequently, assuming that only close proximity affects individual outcomes may disregard relevant contextual influences, and for spatial models that require an a priori definition of the weights for spatial units, it may be erroneous to make a decision based on this assumption. Concerning spatial autocorrelation, we found that neglecting local spatial autocorrelation at the context level causes considerable bias to the estimates, especially for districts that are close to the home district.

Thrust and Torque Characteristics Based on a New cutter-head Load Model

Full face rock tunnel boring machine（TBM） has been widely used in hard rock tunnels, however, there are few published theory about cutter-head design, and the design criteria of cutter-head under complex geological is not clear yet. To deal with the complex relationship among geological parameters, cutter parameters, and operating parameters during tunneling processes, a cutter-head load model is established by using CSM（Colorado school of mines） prediction model. Force distribution on cutter-head under a certain geology is calculated with the new established load model, and result shows that inner cutters bear more force than outer cutters, combining with disc cutters abrasion; a general principle of disc cutters＇ layout design is proposed. Within the model, the relationship among rock uniaxial compressive strength（UCS）, penetration and thrust on cutter-head are analyzed, and the results shows that with increasing penetration, cutter thrust increases, but the growth rate slows and higher penetration makes lower special energy（SE）. Finally, a fitting mathematical model of ZT（ratio of cutter-head torque and thrust） and penetration is established, and verified by TB880 E, which can be used to direct how to set thrust and torque on cutter-head. When penetration is small, the cutter-head thrust is the main limiting factor in tunneling; when the penetration is large, cutter-head torque is the major limiting factor in tunneling. Based on the new cutter-head load model, thrust and torque characteristics of TBM further are researched and a new way for cutter-head layout design and TBM tunneling operations is proposed.

Relationship between Contraceptive Knowledge,Cognition and Behaviors among Vocational High School Students

Objective To study the relationship between contraceptive knowledge, cognition and behaviors among vocational high school students. Methods A cross-sectional survey was anonymously self-administrated by way of computer to all the 1st graders＇ among three vocational high schools in a district of Shanghai. Four cognition indicators, including perceived benefits, perceived barriers, perceived risks and self eJficacy were applied according to Health Belief Model. Results The percentage of respondents who reported ever sexual practices and contraceptives use at first sex was 7.01% and 56.64% respectively. Condom （58. 70%） and oral contraceptive pills （27.78%） were used by the majority. Main reasons for non-use were ＂shy to buy it＂ （26.53%） and ＂partner don＇t want to use any＂ （18.37%）. Proportion of respondents who ever had sex regarded withdrawal and rhythm as effective were 68.35% and 68.42% respectively. Proportion of respondents having sex knew ＂If a person was infected with STDs, he/she might not have noticeable symptoms＂ were 22.86%. Proportion of respondents who reported non-use of contraceptives at first sex considered that ＂infrequent intercourse could not cause a girl pregnant even she had experienced her menstruation＂ were 40.63%. Proportion of respondents who had ever used condom got full score of knowledge on ＂how to correctly use condom＂ were 23,26%. Perceived risks were poorest among four cognition indicators. High level of contraceptive knowledge was connected with high rate of contraceptives use at first sex, whereas high level contraceptive cognition was connected with high rate of contraceptive use both at first and recent sex. Conclusions It is important to provide youth-friendly services as well as message on contraceptives among vocational school students.

Application of the p-Median Problem in School Allocation

This paper focus on solving the problem of optimizing students’ orientation. After four years spent in secondary school, pupils take exams and are assigned to the high school. The main difficulty of Education Department Inspection (EDI) of Dakar lies in the allocation of pupils in the suburbs. In this paper we propose an allocation model using the p-median problem. The model takes into account the distance of the standards imposed by international organizations between pupil’s home and school. The p-median problem is a location-allocation problem that takes into account the average (total) distance between demand points (pupil’s home) and facility (pupil’s school). The p-median problem is used to determine the best location to place a limited number of schools. The model has been enhanced and applied to a wide range of school location problems in suburbs. After collecting necessary numerical data to each EDI, a formulation is presented and computational results are carried out.

AN SIRS EPIDEMIC MODEL

This paper considers an SIRS epidemic model that incorporates constant immigrati on rate, a general population size dependent contact rate and proportional tran sfer rate from the infective class to susceptible class.A threshold parameter σ is identified. If σ≤1, the disease free equilibrium is globally stab le. If σ>1, a unique endemic equilibrium is locally asymptotically stable. For two important special cases of mass action incidence and standard incidence, global stability of the endemic equilibrium is proved provided the threshold is larger than unity. Some previous results are extended and improved.
