Transportation Accessibility

With the development of society, an increasing number of educational institutions have adopted field environmental education activities rather than classroom education. Field education can not only enhance students' environmental awareness but also enable them to fully understand environmental protection knowledge. Ecological protection areas are important bases for educational institutions to organize students to implement field environmental education. Focusing on Zhuhai City, this study explored spatial relationships between educational institutions and ecological protection zones using Kernel density estimation, the two-step floating catchment area method, and Thiessen polygons. Specific actions included measuring transportation accessibility and dividing the service scopes of ecological protection zones to provide field environmental education for educational institutions. These actions provided a helpful reference for educational institutions to conduct field environmental education activities effectively. The results showed the following: (1) Schools in Zhuhai City were mainly located in subdistricts and presented a spatial layout of “one primary and two secondary.” Students were mainly concentrated in villages and towns and presented a spatial layout of “one core and two centers.” Ecological protection zones were scattered in the township area; their spatial relationships with educational institutions were scattered. Meanwhile, their spatial relationship with the number of students was relatively concentrated. (2) In terms of the accessibility of educational institutions to ecological protection zones, the educational institutions in the northeast of Xiangzhou District and the middle of Doumen District had higher accessibility, while the educational institutions in the middle and south of Zhuhai City had lower accessibility, and the educational institutions in the middle of Xiangzhou District had the lowest accessibility. (3) Based on accessibility, the service scopes of field environmental education activities in ecological protection zones were divided into 15 blocks. Here, the educational institutions located in Xiangzhou District, the western part of Jinwan District, and western, middle, and eastern parts of Doumen District had relatively strong spatial dispersions with the ecological protection zones within their blocks, while the educational institutions located in the central and eastern parts of Jinwan District and northern and southern parts of Doumen District had relatively weak spatial dispersions with the ecological protection zones within their blocks.

Chinese characters are constructed by basic strokes based on structural rules. In handwritten characters, the shapes of the strokes may vary to some extent, but the spatial relations and geometric configurations of the strokes are usually maintained. Therefore these spatial relations and configurations could be regarded as invariant features and could be used in the recognition of handwritten Chinese characters. In this paper, we investigate the structural knowledge in Chinese characters and propose the stroke spatial relationship representation (SSRR) to describe Chinese characters. An On-Line Chinese Character Recognition (OLCCR) method using the SSRR is also presented. With SSRR, each character is processed and is represented by an attribute graph. The process of character recognition is thereby transformed into a graph matching problem. After careful analysis, the basic spatial relationship between strokes can be characterized into five classes. A bitwise representation is adopted in the design of the data structure to reduce storage requirements and to speed up character matching. The strategy of hierarchical search in the preclassification improves the recognition speed. Basically, the attribute graph model is a generalized character representation that provides a useful and convenient representation for newly added characters in an OLCCR system with automatic learning capability. The significance of the structural approach of character recognition using spatial relationships is analyzed and is proved by experiments. Realistic testing is provided to show the effectiveness of the proposed method.

Descriptive Method

The aim of this study was to measure the attitudes of students and secondary students in Aqla falcon towards environmental problems. And whether there are statistically significant differences in trends towards environmental problems due to gender variable (student, student). To achieve the objective of the study, the researcher used the descriptive method. A questionnaire (25) was designed to measure trends towards environmental problems. Was applied to a sample of (126) students. After data collection and processing, the results showed that the attitudes of students and students are positive. The results of the study revealed no statistically significant differences in trends towards all environmental problems according to gender variable (student, student). The results also showed no statistically significant differences in the attitudes of male and female students towards all environmental problems according to the educational level of the father and the educational level of the mother. In light of the results, the researcher presented a number of recommendations, most notably: the need to maintain environmental awareness among students to include environmental education in the curriculum at all stages of public education, and the preparation of scientific programs calling for protecting the environment from all sources of pollutants and conservation.

Students Attitudes

Pollution is shown as the environmental challenge, which has the greatest impact on global climate change. Faced with this situation, numerous environmental summits agree on the fact that Environmental Education needs to be implemented within the different disciplines and educational institutions. Therefore, Further Education must foster the research and management of environmental education with the aim of developing responsible citizens with sustainable attitudes. Based on this idea, this paper aimed to analyse the attitudes in Further Education students towards different situations and habits linked to pollution, as well as some of its varied typologies (chemical pollution, acoustic pollution and management of solid urban waste and rubbish). To achieve this, a sample of 307 students from different degrees of Preschool and Primary Education was included, using a questionnaire as a measuring instrument. The methodology of the study was both descriptive, through the analysis of its measures, and inferential, with the preparation of a confirmatory conceptual model through the structural equation model (SEM). Results revealed that students are highly concerned about the different situations proposed, and that the predictive model forges strong correlations between the four variables of the study. Hence, the study focused on the idea of trying to enhance environmental awareness in the groups of students from different educational phases, to subsequently foster the implementation of specific actions aimed at preserving and conserving natural resources, and to guide society towards sustainable development.

Spatial Relationships

Much of the human cortical surface is obscured from view by the complex pattern of folds, making the spatial relationship between different surface locations hard to interpret. Methods for viewing large portions of the brain's surface in a single flattened representation are described. The flattened representation preserves several key spatial relationships between regions on the cortical surface. The principles used in the implementations and evaluations of these implementations using artificial test surfaces are provided. Results of applying the methods to structural magnetic resonance measurements of the human brain are also shown. The implementation details are available in the source code, which is freely available on the Internet.

AbstractReading-related responses in the lateral ventral temporal cortex (VTC) show a consistent spatial layout across individuals, which is puzzling, since reading skills are acquired during childhood. Here, we tested the hypothesis that white matter fascicles and gray matter microstructure predict the location of reading-related responses in lateral VTC. We obtained functional (fMRI), diffusion (dMRI), and quantitative (qMRI) magnetic resonance imaging data in 30 adults. fMRI was used to map reading-related responses by contrasting responses in a reading task with those in adding and color tasks; dMRI was used to identify the brain’s fascicles and to map their endpoints density in lateral VTC; qMRI was used to measure proton relaxation time (T1), which depends on cortical tissue microstructure. We fit linear models that predict reading-related responses in lateral VTC from endpoint density and T1 and used leave-one-subject-out cross-validation to assess prediction accuracy. Using a subset of our participants (N=10, feature selection set), we find that i) endpoint density of the arcuate fasciculus (AF), inferior longitudinal fasciculus (ILF), and vertical occipital fasciculus (VOF) are significant predictors of reading-related responses, and ii) cortical T1 of lateral VTC further improves the predictions of the fascicle model. Next, in the remaining 20 participants (validation set), we showed that a linear model that includes T1, AF, ILF and VOF significantly predicts i) the map of reading-related responses across lateral VTC and ii) the location of the visual word form area, a region critical for reading. Overall, our data-driven approach reveals that the AF, ILF, VOF and cortical microstructure have a consistent spatial relationship with an individual’s reading-related responses in lateral VTC.HighlightsThe ILF, AF, and VOF predict the spatial layout of reading-related responses in VTCGray matter microstructure improves the prediction of reading-related responsesFascicles and gray matter structure together predict the location of the VWFA
